CONTROL DEVICE FOR INJECTION MOLDING MACHINE
Provided is a control device for an injection molding machine, capable of reducing the load on a user, in relation to display image selection. The control device for the injection molding machine comprises: a display unit that displays display images including information relating to molding conditions for the injection molding machine; display image selection buttons that directly summon display images and display the display images on the display unit; and a storage unit that stores a plurality of desired display image selection buttons, as customizable menu display items.
The present invention relates to a control device for an injection molding machine, and particularly, to display of a screen included in a control device.
BACKGROUND ARTAn injection molding machine includes a plurality of devices such as a mold clamping device, an injection device, or a molded part discharging device, as components, and when the injection molding machine is operated, operation conditions should be set by a control device with respect to each of the plurality of devices. In general, in the injection molding machine, a setting screen or an execution value display screen is provided on the control device in each of the plurality of devices or in each of the related devices. Accordingly, in the setting screen of the control device, switching and input between many control screens should be diversely performed.
In general, a display button is provided on each screen, in which a list is displayed on a menu screen, corresponding to each setting screen or each execution value display screen, a screen desired for displaying is selected from menu buttons, and the screen is displayed.
However, the selection of the menu screen is hierarchically logical, the selection of the menu button needs to be repeated a number of times corresponding to the hierarchy in order to reach the desired image, and operability is impaired.
For example, in addition, when a previous display image, which has been displayed before being switched to the setting screen displayed at the present time, is redisplayed, it is necessary to hierarchically select the display image from the menu screen. Particularly, the hierarchical configuration may cause the user to forget which hierarchy at which the desired image has been displayed. Accordingly, even when the desired image is not an image which has been displayed long before, if each hierarchy is not searched for in a trial and error method, an operation time until reaching the desired image lengthens. Accordingly, stress on a user increases, the operation of the injection molding machine is delayed, and productivity decreases.
In order to solve the above-described problems, it has been suggested that a plurality of desired setting screens are displayed to be simultaneously arranged on a display area and are displayed on each screen so as to be scrollable to improve operability (for example, PTLs 1 and 2).

[PTL 2] Japanese Unexamined Patent Application Publication No. 2006-97671
SUMMARY OF INVENTION Technical ProblemAccording to PTLs 1 and 2, the operability is improved by displaying a plurality of setting images on one display screen. However, since it is assumed that selection of an image is hierarchically performed, there is still room for improvement of the operability.
Accordingly, an object of the present invention is to provide a control device for an injection molding machine capable of reducing a load on a user with respect to selection of a display image.
Solution to ProblemA control device for an injection molding machine according to the present invention including: a display unit which displays a display image including information relating to molding conditions of an injection molding machine; a display image selection button which directly summons the display image and displays the display image on the display unit; a storage unit which stores a plurality of desired display image selection buttons as customizable menu display items; and a control unit which controls the display of the display image and the display of the customizable menu on the display unit.
In the control device of the present invention, the plurality of desired display image selection buttons are stored in the storage unit as customizable menu display items. Accordingly, when a user searches for a desired display image selection button from menu screens including display image selection buttons which have low use frequency or do not match the user's operation skill or operation procedure, since the user can select a desired display image without performing an unnecessary operation, it is possible to increase operation efficiency with respect to the display image selection and reduce a load on the user.
Preferably, the storage unit further stores one user ID or a plurality of user IDs assigned to each user, and one customized menu display item or a plurality of customized menu display items associated with the one or the plurality of customized menu display items. In this case, when one user ID among the plurality of user IDs is input, the control unit can read the customized menu display item associated with one user ID from the storage unit and can display the display image including the customized menu display item on the display unit.
In addition, the control unit learns which of a plurality of the display images have high use frequency with respect to the user for each user ID, and can store the plurality of display images by learning in the storage unit as the customized menu display item.
Preferably, a procedure in displays including the customized menu display item, a display layout, and a display hierarchy causes the user to selectively operate the desired display image and associate the display image with the user ID and hence to be stored in the storage unit. In this case, since the display image, in which the set item considered to be important by the user is included, can be manually registered as the customizable menu display item according to the user's intention regardless of the use frequency and can be displayed as a menu, it is possible to increase operation efficiency.
Moreover, the storage unit can store the plurality of user IDs assigned to each user, a group ID being shared with the plurality of user IDs, and a customized menu display item which is associated with and shared with the customized menu display item. In this case, when one user ID among the plurality of user IDs is input or the group ID is input, the control unit can display the shared customized menu display item.
Moreover, the storage unit may further store the plurality of user IDs assigned to each user and a security level of each user ID while associating the security level of each user ID with the customized menu display item. In this case, when one user ID among the plurality of user IDs is input, the control unit can display the customized menu display item according to the security level.
In addition, preferably, the storage unit further stores a plurality of mold IDs assigned to each mold, and a plurality of preset important parameter display items among the molding conditions associated with the plurality of mold IDs. In this case, when one mold ID among the plurality of mold IDs is input, the control unit can read the molding conditions and important parameter display items associated with one mold ID, and can preferentially display the display image including the important parameter display item on the display unit.
Moreover, the control unit may learn which of the plurality of display images have high use frequency with respect to the user for each mold ID, and may automatically store the plurality of display images by learning in the storage unit as the customized menu display item. In addition, similarly to the above-described case, preferably, the customizable menu display item can be manually registered for each mold ID.
Moreover, preferably, the storage unit further stores a plurality of management numbers assigned to each molded part, and a plurality of preset important parameter display items among the molding conditions associated with the plurality of management numbers. In this case, when one management number among the plurality of management numbers is input, the control unit can read the molding conditions and important parameter display items associated with one management number, and can preferentially display the display image including the important parameter display item on the display unit.
Advantageous Effects of InventionAccording to the present invention, a plurality of desired display image selection buttons are stored in a storage unit as the customizable menu display item. Accordingly, since a user can select a desired display image from menu display items, it is possible to reduce a load on the user with respect to selection of the display image.
A right drawing of
Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.
An injection molding machine 1 of the present embodiment includes a molding machine main body 10, and a control device 20 which controls operations of the molding machine main body 10. An injection molding machine 1 has characteristics with respect to a method for performing display on a display unit 29 included in the control device 20. In addition, the present embodiment is described with reference to the injection molding machine which is driven by a hydraulic actuator (hydraulic mechanism). However, instead of a hydraulic actuator, an electric actuator which is driven by an electric motor such as a servo motor, an inverter motor, or an interior permanent magnet motor may be applied to the injection molding machine 1.
The molding machine main body 10 includes a mold clamping unit 11 and a plasticizing unit 15.
The mold clamping unit 11 includes a stationary platen 12 to which a fixed mold (not shown) is attached, and a movable platen 13 to which a movable mold (not shown) is attached. The mold clamping unit 11 includes a hydraulic mechanism which moves the movable platen 13 toward the stationary platen 12, and before injection molding is performed, the mold clamping unit 11 moves the movable platen 13 and causes the movable mold to come into contact with the fixed mold. In addition, after pressure of hydraulic oil of the hydraulic mechanism increases, the movable mold and the fixed mold are clamped to each other to perform mold clamping, a molten resin is injected from the plasticizing unit 15 to a cavity formed between the movable mold and the fixed mold, and a molded part is obtained.
The plasticizing unit 15 includes a heating cylinder 16 in which a discharging nozzle is formed on a front side which is the mold clamping unit 11 side, and a screw (not shown) which is provided in the inner portion of the heating cylinder 16. The plasticizing unit 15 also includes components such as a drive source (not shown) which moves the screw forward and rearward, a drive source (not shown) which rotates the screw normally or reversely, or a fuel hopper (not shown) for supplying a resin fuel into the inner portion of the heating cylinder 16.
In the plasticizing unit 15, when the screw rotates, for example, a pellet-shaped thermoplastic resin supplied from the fuel hopper is transported to the front side of the heating cylinder 16. In the transport process, the resin pellets are gradually heated and melted, and accumulate at the front side of the screw. The screw receives pressure of the resin generated by the accumulation, and measures a predetermined amount of molten resin at the front side of the screw while moving toward the fuel hopper side. Thereafter, a predetermined measured amount of molten resin is injected from the discharging nozzle into the cavity formed between the fixed mold and the movable mold of the mold clamping unit 11.
In order to obtain the molded part using the injection molding machine 1 including the above-described elements, the following processes are performed in order. That is, the molded part is obtained via a mold clamping process of closing the movable mold and the fixed mold and performing mold clamping at high pressure, a plasticization process of heating, melting, and plasticizing the resin pellets in the inner portion of the heating cylinder 16, an injection process of injecting the plasticized molten resin into the cavity formed between the movable mold and the fixed mold and filling the cavity with the resin, a cooling process of cooling the molten resin filling the cavity until the molten resin is solidified, a mold opening process of opening the mold, and an extraction process of extracting the molded part cooled and solidified in the cavity.
The molding machine main body 10 includes various sensors in the mold clamping unit 11 and the plasticizing unit 15, and sensing information SR which is obtained by the sensors while the above-described processes are performed is sent to the control device 20. For example, as the sensing information, there is a molding clamping pressure, an injection pressure, or the like.
The control device 20 generates operation command information OC using the sensing information SR sent from the molding machine main body 10 or using information prepared by the control device 20 in advance so that the molding machine main body 10 performs operations required for the processes such as the mold clamping process, the plasticization process, or the injection process, and sends the operation command information OC to each driving unit of the molding machine main body 10. Each driving unit of the molding machine main body 10 performs operations required for performing the injection molding, based on the received operation command information OC.
The control device 20 includes a processing unit 20a and a storage unit 20b (control unit), and the processing unit 20a reads various information stored in the storage unit 20b according to instruction and selection from a user and displays the information on the display unit 29.
The operation command information OC is generated in the control device 20 based on various set values, selection of an operation, selection of a display image, or the like which is input to the control device 20 by the user operating the injection molding machine 1. Here, the “input” includes an action which selects specific information from a menu.
The control device 20 includes a man-machine interface 21, and a worker inputs various information to the control device 20 via the man-machine interface 21. The man-machine interface 21 includes various switch buttons 23, a soft and hard key input unit 25, and a touch panel 27.
As the switch button 23, there are various switches such as a switch for turning on and off a power source of the control device 20, a switch for turning on and off a power source of the molding machine main body 10, a tiltable switch for selecting movement and a movement direction of a device, or a switch in which a lamp is lit, made to flicker, or extinguished by turning on and off a switch.
In addition, the switch buttons 23 may be provided so as to correspond to various operations of the molding machine main body 10. For example, a switch button 23 corresponding to the molding clamping process, a switch button 23 corresponding to the injection processing, or the like may be provided. In this case, the switch button 23 may be configured to include a menu button.
The key input unit 25 allows selection of the above-described processes, input of a set value required for performing the selected process, or selection of information displayed on the display unit 29. A keyboard of a computer device including keys corresponding to an alphabet and numeric keypads corresponding to numbers of 0 to 9 may be used as the key input unit 25, and a keyboard which is developed on a touch panel may be also used as the key input unit 25. Information input from the key input unit 25 is sent to the control device 20.
The touch panel 27 includes a touch information detection unit 28 (hereinafter, referred to as a detection unit 28) and a display unit 29, and is a device in which the detection unit 28 specifies a position of a touched area when the surface of the display unit 29 is pressed (touched), and which can perform operations corresponding to the touched area and has both a function of a display device and a function for allowing input.
As shown in
In the display unit 29, in order to select the display image, as shown in
In addition, as shown in the lowest layer of
In addition, preferably, the menu buttons in which the display selection buttons of the operation screens of each mold or each target molded part are collected is stored, and the menu buttons are summoned so as to be displayed. In general, operation parameters of the molding machine greatly influencing high quality molding are different from each other in each mold or each molded part. Accordingly, the menu buttons are customized to the setting screens including parameters greatly influencing each mold or each molded part, the selection time of the user on the display screen is reduced by decreasing the number of menu display items of the select screen, and it is possible to effectively increase the operating efficiency.
In addition, preferably, a plurality of menu buttons are stored in the same ID. In this case, when the control device 20 identifies the ID of the user after the control device 20 reads the molding conditions of a predetermined mold or molded part, the control device 20 collates the ID of the user with the mold or the management number of the molded part, and the user reads the menu list of the operation screen in which the user has been mainly used with respect to the mold or the molded part from the storage unit 20b and prepares the menu list so as to display the menu list on the display unit 29. In addition, this is similarly applied to a case where the control device 20 reads the molding conditions of a predetermined mold or molded part after the control device 20 identifies the ID of the user. In a case where operation screens having increased operating efficiency for each user are different from each other when the molded parts are different from each other, each user easily selects the molding conditions independently. In addition, it is possible to always summon the menu buttons of the operation screen, which is considered to be preferable for each target molded part by the user, from the storage unit 20, and it is possible to increase workability.
Moreover, preferably, after the menu buttons of each ID of the operation screen registered on the storage unit 20b in advance, or the menu buttons of each management number of the mold or a product is read, the menu buttons are edited, the edited menu buttons may be stored in the storage unit 20b so as to be updated. In this case, when the menu buttons are improved so that the user more easily uses the menu buttons, the menu buttons of the latest operation screen can always be summoned, and it is possible to effectively increase workability.
Moreover, the storage unit 20b of the customized menu buttons may be provided on the control device 20 of the injection molding machine 1, and may be provided on a centralized management device (not shown) which manages a plurality of injection molding machines in a centralized manner. In the case where the storage unit 20 is provided on the centralized management device, irrespective of which injection molding machine which is managed by the centralized management device, a user can use the their own customized menu buttons. Accordingly, it is not necessary to customize the menu button for each injection molding machine so as to be stored in the storage unit, and it is possible to increase the operating efficiency.
In addition, even when the storage unit 20b of the customized menu button are provided on the control device of the injection molding machine 1, a plurality of control devices for injection molding machines are connected to each other by communication, and the customized menu buttons may be summoned from the mutual storage devices so as to be shared. Specifically, a control device for an injection molding machine (referred to as a control device A) identifying the ID of the user searches to find another control device for an injection molding machine (referred to as a control device B) which stores the menu buttons customized by the user. The control device A receives the menu buttons with respect to the ID of the user via communication from the control device B, and may display the menu buttons on the display device of the control device A.
Moreover, the customized menu buttons may be copied or moved so as to be stored in well-known arbitrary external storage media (external hard disk, USB memory, SD card, or the like) from the storage unit 20b, and may be used so as to be stored in storage units such as another injection molding machine or centralized management device, or a stand-alone computer or printer.
The display unit 29 displays the image corresponding to the input (selection) from the menu buttons, the key input unit 25, or the like which is displayed on the display unit 29. The information related to the display image is held in the storage unit 20b (hereinafter, may be referred to as a data storage unit 20b) of the control device 20, and is read from the data storage unit 20b according to the selection of the user so as to be displayed on the display unit 29. For example, in
When two display images are displayed, in the display unit 29, the display image required to be displayed first is displayed on the first display area 31, and the display image required to be displayed thereafter is displayed on the second display area 32. That is, in the present embodiment, the display image having an older position in the display history is displayed on the first display area 31 positioned on the upper side, and the display images having a newer position in the display history are displayed on the second display area 32 positioned on the lower side. However, the positions of these areas may be exchanged between the upper side and the lower side. For example, in a step in which the setting image of only the injection process is not read, the first display area 31 may be a blank screen. In addition, a default image may be set in advance, and the default image may be automatically displayed on the first display area 31 and the second display area 32 of the display unit 29 as an initial screen after power sources input power. Here, for simple description, the case where the first display area 31 is a blank screen as the initial screen is described. However, for example, when the setting image of the plasticization process is read, the setting image of the injection process is displayed on the blank first display area 31, and the setting image of the plasticization process is displayed on the second display area 32. Alternatively, in a step in which the setting image of only the injection process is not read, the setting image of the injection process may be displayed on the first display area 31, and the second display area 32 may be a blank screen. In this case, for example, when the setting image of the plasticization process is read, the setting image of the plasticization process is displayed on the blank second display area 32 in the state where the setting image of the injection process is displayed on the first display area 31.
The setting images of the injection process are hierarchized, the setting image displayed on the first display area 31 of
The display unit 29 of the present embodiment includes the standard display mode in which each of display images different from each other is displayed on each of the first display area 31 and the second display area 32. However, in a state where a relative positional relationship between image information (hereinafter, may be referred to as a first display image P1) displayed on the first display area 31 and image information (hereinafter, may be referred to as a second display image P2) displayed on the second display area 32 is maintained, it is possible to synchronously scroll the first display image P1 and the second display image P2. Hereinafter, with reference to
[Synchronous Scroll Function (
In the standard display mode as shown in
For example, when an instruction for scrolling the displayed image is input to the key input unit 25, as shown in
For easy understanding, in
According to the present embodiment, when the scroll instruction is applied to the first display image displayed on the first display area 31 and the second display image displayed on the second display area 32, two display images vertically adjacent to each other can be vertically scrolled and displayed in the state where two display images are synchronized and connected to each other. Therefore, according to the present embodiment, when the display image (previously displayed image) which is not displayed at the present time is required to be redisplayed, it is possible to display the previously displayed image by simply performing the scroll instruction. Accordingly, in the present embodiment, since work such as in a case where a user must remember the name of the previously displayed image while depending on the user's memory or the user selects the previously displayed image from the menu screen again is not required, it is possible to reduce a load on the user.
Moreover, in the present embodiment, since the setting images can be scrolled and displayed in the order as in the operation history and the screen selection history, if an user has displayed the image, even when the user's memory is unreliable and the user does not remember the hierarchy, it is possible to display the image which is not displayed at the present time by simply performing the scrolling. Therefore, it is possible to reduce the operation time and increase productivity.
In addition, since the display unit 29 is divided into the first display area 31 and the second display area and the first display image and the second display image are simultaneously displayed, the setting screens of other processes are not displayed in a reduced form or are not partially displayed, the setting screens are displayed on the entire screen, and the user can input conditions while checking all setting values on the screen.
Accordingly, it is possible to input and change the setting values while reviewing the setting values closely related to each other in a series of mechanical operations even if the mechanical operations are different from each other. Accordingly, unlike a method in which one display image is displayed on one display area, labor in which the user switches the display images one by one and checks the display images, or labor in which the user identifies small characters which are difficult to see due to the reduction of the image, or labor in which the user switches the image to other portions of the same screen to display the image is removed, and it is possible to prevent input errors due to confusion in the user's memory or the user's misunderstanding.
In addition, since the display images are displayed on the first display area 31 and the second display area 32 according to the selected order, when the user sets the operation conditions of a machine, in a case where the user has a setting procedure according to the user's own know-how, it is possible to realize the disposition of the setting image according to the effective setting procedure set by the user. Therefore, according to the present embodiment, it is also possible to customize the display procedure with respect to the operation manner of each user. In this case, preferably, the ID is assigned to each user in advance, a storage area of the control device is allocated to each ID, and the connection procedure and the layout of the operation screens are stored for each ID of the user and are summoned so as to be displayed. In addition, preferably, the connection procedure and the layout of the operation screens are stored for each mold or each target molded part, and are summoned so as to be displayed. In addition, preferably, if the connection procedures and the layouts of a plurality of operation screens can be stored in the same ID, when the preferable layout having high operating efficiency for setting screens is changed depending on the target molded part or the like, the connection procedure and the layout of the preferable operation screen of each target molded part can always be summoned from the storage unit 20b.
Moreover, customization processing of the layout may be performed by an operation of the user of storing the setting image, which is actually displayed when the user selects the molding conditions, and the display history in the storage unit 20b, or may be performed by an operation of providing a dedicated customization processing screen, allowing the user to select the setting screen on the dedicated screen, to set the layout, and to perform the customization, and storing the customization in the storage unit 20b. Alternatively, the setting images which are frequently used by the user and the display procedures are learned by the control device 20, and the control device 20 automatically set the layout of each ID, and store the layout in the storage unit 20b.
Moreover, preferably, after the connection procedure and the layout of the operation screen registered in the storage unit 20b in advance are read and edited, the connection procedure and the layout of the edited operation screen are updated and stored in the storage unit 20b. In this case, when the connection procedure and the layout are improved so that the user easily uses the connection procedure and the layout, since the connection procedure and the layout of the latest operation screen can always be summoned, it is possible to effectively increase workability. In addition, it is needless to say that the menu buttons of each ID of the operation screen registered in the storage unit 20b in advance, or each management number of the mold or the product is read and edited, and may be stored as a menu different from the read menu.
In addition, according to the user's memory such as “has displayed before . . . ”, since the display procedure of the screen can be intuitively reflected in an operation, the operation can be performed according to the image of the user, and it is possible to reduce stress on the user during the operation. In addition, in order to rapidly display a desired image which has been displayed before a plurality of pages, the scroll amount may be specified by a number such as the number of pages, and the image may be switched by jumping to a desired image. Moreover, the scroll speed may be set so as to be switched in a plurality of steps in advance, and the scroll speed is switched to a desired scroll speed by directly selecting the desired scroll speed or the scroll speed may be automatically switched to the desired scroll speed by a predetermined touch action. In addition, a text search function or a code search function is provided in the control device 20 in advance, and when a keyword of a desired screen or the cord is searched for, the desired screen can be displayed.
The scroll may be performed by pressing soft switches or hard switches such as sheet keys on the touch panel, and may be performed by a touch action operation of moving the image in the scroll direction while touching the touch panel, that is, a so-called swipe operation. Alternatively, the scroll instruction may be performed using a method by which the instruction in the scroll direction is acoustically recognized according to voice of the user.
In addition, switching between a method of displaying a new setting image by inserting the new setting image from above the display unit 29 and scrolling the image downward and a method of displaying the new setting image by inserting the new setting image from below the display unit 29 and scrolling the image upward can be selectively set according to the user's own convenience. Accordingly, since the scroll direction matching the image of the user can be selected, that is, the display switching can be tailored for a user using an image which is viewed by scrolling down a new image from the history, or a user using an image which is viewed by scrolling up a new image from the history, it is possible to remove inconvenience such as misunderstanding or discomfort.
[Switching Between Standard Display and Extension Display (
As described above, the present embodiment includes the standard display mode and the extension display mode. However, hereinafter, with reference to
In
In the trend data, the operation data of a molding cycle of the past is listed as the history of each molding cycle, and if many molding cycles overlap each other, the data which cannot be completely received in the first display area 31 by the standard display mode occurs, and the data is hidden in
In a display image group having the hierarchical configuration in which there is a lower display image with respect to an upper display image, the upper image is displayed on the first display area 31 or the second display area 32. In this case, when there is an instruction of the user to display the extension display mode on the upper display image, a pair of display images in which the upper display image is disposed in the first display area 31 and the lower display image is disposed in the second display area 32 may be display of a hierarchical configuration.
In addition, conversely, when the lower display image is displayed in the first display area 31 or the second display area 32, in a case where there is an instruction of the user to display the extension display mode on the lower display image, a pair of display images in which the upper display image is disposed in the first display area 31 and the lower display image is disposed in the second display area 32 may be display of a hierarchical configuration.
The switching from the standard display mode to the extension display mode and the return (switching) from the extension display mode to the standard display mode are performed according to the instruction of the user. This instruction may be any instruction. For example, it may be assumed that the instruction is input from the key input unit 25 in which the area (in the present embodiment, the first display area 31 in which the trend data is displayed) in which the image required to be set to the extension display mode is displayed is touched by the user.
Moreover, in order to prevent incorrect display of the display image, the display images in which the extension display mode can be used may be limited to images of only the data list such as a trend data list or a control signal list.
[Automatic Insertion and Scroll Function of New Selection Image Information (
Next, automatic insertion and a scroll function of new selection image information which are other characteristic display methods of the present embodiment will be described.
For example, as shown in
As shown in
When the user ends the conditions input required for the sub-setting image and redisplays the setting image of the initial injection process and the initial main setting image, both images are synchronized so as to be scrolled downward by the instruction of the user and are displayed on the first display area 31 and the second display area 32 as shown in
In addition, in this case, when the user want to perform the setting operation according to the new setting images while viewing the main setting image of the plasticization in the state in which the sub-setting image is made to disappear downward, for example, when the user selects the setting image of the molding clamping process and displays the setting image, the main setting image is displayed as the first display image P1 displayed on the upper side of the display unit 29, and the setting image of the mold clamping process is displayed as the second display image P2. In this case, in the display history stored in the storage unit 20b, the setting image of the mold clamping process is inserted between the main setting image and the sub-setting image. Accordingly, if the user performs the upward scroll operation in the state where the main setting image is displayed as the first display image P1 and the setting image of the molding clamping process is displayed as the second display image P2, the first display image P1 is displayed on the setting screen of the mold clamping process, and the sub-setting image is displayed as the second display image P2.
According to the insertion method of the new selection image of the present embodiment, the setting image newly selected at an arbitrary position in the display history is displayed so as to be adjacent to the setting image positioned at a position above an arbitrary position, and the old setting image in the display history can be automatically removed from the display unit 29. Accordingly, the images which are required to be certainly displayed by the user at the present time are simultaneously displayed without performing the operation in which the user instructs the scrolling, and it is possible to rapidly perform the setting operation of the conditions. Therefore, it is possible to reduce an operation load on the user.
The insertion method of the new selection image of the present embodiment may be also applied to a case in which the new display image is required to be displayed when the old display image in the display history is displayed in the extension display mode. Accordingly, the new display image is displayed in the extension display mode, and it is possible to interrupt the display of the old display image (extension display mode) in the display history.
In addition, when the display images having the older positions in the display history are displayed in the extension display mode, if there is a request for displaying the new display image, the display images having the older positions in the display history are redisplayed in the standard display mode, the new display image is displayed in the standard display mode, and the new display image may be displayed above or below the display image having the older position in the display history according to an anteroposterior relationship in the display history.
In addition, the display images having the older positions in the display history are displayed in the standard display mode, when it is required to display the new display image in which a default display mode is the extension display mode, the display images having the older positions in the display history displayed in the standard display mode slides upward or downward, and the new display images may be displayed in the extension display mode.
[Scroll Lock Function of Display Image (
In the present embodiment, in principle, the image displayed on the first display area 31 and the image displayed on the second display area 32 are synchronized and scrolled. However, there is also an exception. The exception is a scroll lock function of the display image. As described below, this function is effective in a case where the conditions of the process which is effective in other high quality molding are set and input while referring to the operation setting of the process which becomes a center as the molding conditions by which different high quality molding is performed according to the trend list or the molded part.
For example, the trend list image, the setting image of the injection process, and the setting image of the plasticization process are previously selected, and as shown in
In the state in which the trend list image is locked, even when the user performs the operation of instructing the scrolling, as shown in
Moreover, when the first display image is displayed on the first display area, the second display image is displayed on the second display area, and one of the first display image and the second display image is locked, in a case in which the user performs locking of the other display image, the lock of the one display image which has been locked until now may be released. Specifically, for example, when locking of the second display image is performed in the state where the first display image is locked, the second display image is locked, and simultaneously, the lock state of the first display image may be released.
In addition, both the first display image and the second display image may be locked so as not to be scrollable. In this case, for example, it is possible to prevent the screen from being switched due to a portion of a body of the user or a portion of a member held by the user coming into contact with a scroll operation portion due to a mistake or the like of the user and an unintentional scroll operation being performed. Moreover, the scroll lock may be limited to being released by a specific user with a preset ID.
As described above, since the present embodiment includes the lock function of the scrolling, it is possible to set the conditions of two processes of the injection process and the plasticization process while always directly referring to the trend list, and it is possible to reduce the load of the setting operation of the user. In addition, the image to which the lock of the scrolling can be applied is not limited to the trend list, the lock can be applied to an arbitrary image laid out at an arbitrary position in other display histories, and other scrollable images in the state where one of arbitrary images is locked are not limited to the injection process and the plasticization process, and an arbitrary image can be scrolled.
[Name Display Function of Front and Rear Image Information (
Next, a function of displaying names of front and rear information which is not displayed on the display unit 29 will be described with reference to
For example, as shown in
Even when a short time elapses after the user inputs the conditions with respect to the setting image of the injection process while referring to the trend list image, the user may forget the history. Accordingly, in the present embodiment, information capable of specifying the image information having the older position in the display history and the image information having the newer position in the display history which are not displayed at the present time, for example, names are displayed. In this example, a name such as a “mold opening and closing” is displayed on the first display area 31 as the image information having the older position in the display history, and a name such as “plasticization” is displayed on the second display area 32 as the image information of the new display history. The image information having the older position in the display history having the displayed name is older by one generation than the trend list image displayed on the first display area 31. In addition, the image information of the new display history having the displayed name is newer by one generation than the setting image of the injection process displayed on the second display area 32. Moreover, in the present embodiment, the names of the displayed images are the name of the image which is older by only one generation and the name of the image which is newer by only one generation. However, the names of the images which are older or newer by a plurality of generations, that is, one or more generations, for example, two generations, three generations, or the like may be displayed so as to be listed so that sequence of a display history can be understood. In this case, all the names of the images in a plurality of predetermined generations may be displayed from the beginning. However, in order to effectively use the limited display area such as displaying the setting input units of the operation conditions, preferably, initially, the name of the image which is older by only one generation is displayed, and the image names are displayed according to a multi-step type switching so that the image names of the plurality of predetermined generations are displayed by a predetermined operation.
As described above, according to the control device 20 including the name display function of the front and rear image information, with respect to an arbitrary image laid out at an arbitrary position in the display history, it is possible to recognize the image displayed before or after the image displayed at the present time, specifically, in the present embodiment, the setting image of the “plasticization” or the setting image of the “mold opening and closing”. Therefore, according to the present embodiment, even when memory of the user is unreliable, it is possible to easily scroll and redisplay images according to unreliable memory of the user.
[History Erasure Function of Display Image (
The control device 20 of the present embodiment stores the selected display images in a history. However, if a number of display histories increases, the load on the user may increase. Accordingly, the control device 20 can have a function of erasing an arbitrary display image, which is laid out at an arbitrary position in the display history, from the display history.
For example, as shown in
For example, in some cases, the user ends the input of the conditions required for the sub-setting image A, and thereafter, the user may determine that it is not necessary to display the sub-setting image A. In addition, with respect to the plasticization process, when another sub-setting image B exists, if the sub-setting image B is newly selected and appears in the display history, thereafter, unnecessary sub-setting images A are displayed one by one, and the operation efficiency of the scrolling of the user may deteriorate. Accordingly, if unnecessary sub-setting images A exist, it is not possible to display the sub-setting image B so as to be adjacent to the setting image of the plasticization process positioned in the upper hierarchy. Accordingly, the control device 20 includes the function of erasing the unnecessary display images from display histories stored in the storage unit 20b according to the instruction of the user. That is, if instructions for erasure from the display history such as touching on an erasure switch or performing touch action for erasing are given to the sub-setting image shown in
As described above, since the control device 20 including the history erasure function of the display image can display only the necessary image information, the user does not feel stress due to unnecessary images being displayed, and the injection molding machine 1 having high operability is provided.
[Exchange Function Between First Area and Second Area (
The control device 20 of the present embodiment is operated according to the rule in which the image information having the older position in the display history is displayed on the first display area 31 and the image information having the new display history is displayed on the second display area 32. However, for example, the user operating the injection molding machine may habitually display the setting image of the injection process on the first display area 31 and the setting image of the plasticization process on the second display area 32. However, the user may erroneously set the procedure of the selection, and the user may display the setting image of the plasticization process on the first display area 31 and the setting image of the injection process on the second display area 32 (the right drawing of
In order to change the disposition of the images set according to habit of the user, after the display histories of the setting image of the plasticization process and the setting image of the injection process are erased, the setting image of the injection process and the setting image of the plasticization process may be selected again in this order. However, since this causes a load on the user, the control device 20 includes a function of exchanging an arbitrary image laid out so as to be adjacent to the image displayed on the first display area 31 and the display history displayed on the second display area 32. The left drawing of
The operation of performing the exchange function of the images may be performed according to any method. For example, a button for instructing the exchange may be provided on the display unit 29, a command for instructing the exchange function may be assigned to a specific key of the key input unit 25, and the exchange operation of the screen may be performed by a predetermined touch action.
[Horizontal Scroll Function (
In the control device 20 of the present embodiment, in principle, the scrolling is performed in the vertical direction. However, scrolling in the horizontal direction may be required or may be effective to increase the efficiency of the setting operation of the user. Accordingly, as described below, the control device 20 allows an arbitrary image laid out at an arbitrary position in the display history to the scrolling in the horizontal direction.
For example, as shown in
When the user ends the input for the control constants required with respect to the constant setting image of the first page displayed on the second display area 32, in order to input the control constants required with respect to the constant setting image of the next and second page, the user instructs the scrolling in the horizontal direction X. Accordingly, as shown in
In addition, the right position and the left position of the constant setting images of the first to third pages may be conversely disposed. Moreover, switching between the right and left positions and switching between the scroll directions may be performed by a touching operation of one touch type or a switch operation.
In this case, the method of instructing the scrolling may be performed by any method. For example, a swipe operation in which the surface of the second display area 32 is traced in the horizontal direction X may be applied, or a key assigned to the key input unit 25 may be operated. In addition, as shown in
In addition, both display images displayed on the first display area 31 and the second display area 32 may be scrolled in the horizontal direction X independently or synchronously.
In the present embodiment, the constant setting images of the three pages are arranged in the horizontal direction X in advance. However, a method for realizing the arrangement may be performed by any method. For example, the constant setting images of the three pages may be stored in the control device 20 as one determined piece of information, and when the constant setting image is selected from the menu, after the constant setting image are developed on three pages, the constant setting images are arranged in the horizontal direction X. In addition, the information of the constant setting images of three pages are stored in the control device 20 for each page, and if some pieces of the image information of one page are selected, the other image information of two pages is simultaneously selected and can be arranged in the horizontal direction X. In the method of the latter, the portions between the image information of three pages are linked to each other.
In addition, the images arranged in the horizontal direction X are not limited to the constant setting image. For example, setting images or data list images of a plurality of processes closely related to each other may be associated with each other, and may be stored in the storage unit 20b. In addition, when some images are selected and displayed, the image associated with the image, to which the scroll instruction is given in the horizontal direction X, may be scrolled and displayed in the horizontal direction X. For example, a sub-setting screen may be associated with a main-setting screen of the plasticization process, and when the scroll instruction in the horizontal direction X is performed in the state where the main setting image is displayed, the sub-setting screen may be displayed. In addition, a large number of data lists such as trend data lists or control signal lists displayed in the extension display mode may be scrolled and displayed in the horizontal direction X in the state where the extension display image is maintained. Moreover, in a case where the display modes obtained by switching to the extension display mode are a pair of display images configured of an upper display image and a lower display image having a hierarchical configuration, when the plurality of lower sub-setting image groups are associated with the upper main setting image, the main setting image is not scrolled and displayed in the horizontal direction X, and only the lower sub-setting image groups can be scrolled in the horizontal direction X.
As described above, in the control device 20 having the horizontal scroll function, since it is possible to input the required control constants while referring to the setting image of the plasticization process by simply scrolling the constant setting images of three pages, workability increases. In addition, according to the present embodiment, since the constant setting images of three pages can be arranged in the horizontal direction X without selecting the constant setting image of each page individually from the menu screen, it is possible to simplify the menu screen.
Hereinbefore, the present invention is described with reference to the embodiment. However, the configurations described in the embodiment may be selected and be appropriately modified so as to be other configurations without departing from the gist of the present invention.
For example, the display unit 29 has the vertically long display area. However, the display method of the present invention may be also applied to display means including a horizontally long display area. In this case, synchronization of the scrolling is performed along the horizontal direction X.
Moreover, the present invention includes the standard display mode and the extension display mode. However, the present invention may include other display modes. For example, if necessary, the present invention may include a display method of dividing the display area into four. In addition, the display image may be displayed so as to be locally enlarged.
Moreover, in the present embodiment, according to the standard display mode, the display area is divided into two equal parts. However, the display area of the first display area 31 and the display area of the second display area 32 may be different from each other. For example, the division may be performed so that a ratio between the display area of the first display area 31 and the display area of the second display area 32 becomes 6:4, and it is possible to change the ratio between the display areas of the first display area 31 and the second display area 32 based on the instruction from the user while adopting bisection as the default.
Moreover, the display history stored in the storage unit 20b and the user ID may be read by the control device 20 again according to operations of the molding conditions input or the like by the user, or the display history may be initialized by a reset operation of the display history, and the connection procedure or the layout of the operation screen may be stored in the storage unit 20b associated with the ID of the user may be read again and may be displayed on the display unit 29.
In addition, the display image which has been displayed before two generations in the display history, for example, the setting image of the injection process may not be scrolled and redisplayed, and the setting image of the injection process may be newly selected again from the menu and may be displayed. In this case, preferably, the display history of the setting image of the injection process before two generations in the display history is erased.
Moreover, when the power source of the control device 20 is turned off, the display history may be reset, or when the display history is stored in the storage unit 20b immediately before the power source is turned off and the control device 20 turns on the power source again, the display history stored in the storage unit 20b immediately before the power source is turned off may be read and may be displayed on the display unit 29.
