With some methods, one can achieve a position-precise or relatively precise fastening of the areas of the flat materials that are to be connected to one another for the roller exchange, using the beginning, or connection location, of the roller that is positioned as the successor roller, with the precision-accurate, or precision-precise fastening or relatively precise fastening, or joining, of the respective portions being done by use of a clamp rail which, in turn, is fastened outside of the supply unit and/or outside of the connecting station provided there for the roller exchange, under use of a gradation gauge, or the like caliper means, that is provided for the commencement portion of the flat material of the connection roller, or exchange roller.
This signifies that the clamp rail that is provided at the commencement region of the flat material of the exchange roller must or should be transported, together with this exchange roller, to the connecting station and must or should then be fastened there to the element that is configured to position, which action may require and/or desire, at least, significant and/or a relatively luxurious handling, and is not often practicable in the case of a cramped work space.
OBJECT OR OBJECTSAn object, or task, of the present application is to simplify the provision of an exchange roller for replacing a depleted roller by a replenishing roller, or exchange roller.
SUMMARYFor the solution of this task, a procedure is disclosed as is substantially taught as a procedure providing the realization of a roller exchange, at a supply unit which serves for supplying of a sheet, or strand, and the like level material, to a packaging machine, or such like processing machine, from a stock of such flat material that is wound in roller form, or that is wound into rollers, or is in roller form, and, in each case, for the roller exchange, in a connection station, or connecting station, the level material of the roller that is located in use is connected to a leading, or connection, area of an at-ready connection roller. This connection area, or extent of the material, being precisely or generally positioned at an element configured to position, and upon connecting of the level material, is severed from the roller used up to the time of the roller exchange. For the exact or general positioning of the respective connection area of the flat, level material of the connection roller in the connection station, or welding and/or severing connecting station, is fastened, by clamping, to the element configured to position that is provided in the station. A supply unit, or roller supply unit, for the realization of this procedure is indicated, or disclosed, or taught, by a supply unit for supplying of a level material to a packaging machine, or such like processing machine, with at least two roller-receiving structures, that are configured, in each case, for the carrying of a level material-stock, in form of a roller, in which at least one roller forms the roller located so as to be in use, from which the level material is drawn off during the operation of the packaging machine, or such like processing machine. At least one further roller provides the function of a connection roller being ready for the roller exchange; with a connecting station through which is passed the level material of the roller that is in use and a connection area, of the level material of the connection roller, at a connecting position, for the purpose of a transition-correct connection, is precisely or generally positioned at a holding and connection element. The holding element and/or the element configured to position, is a clamp roller that is configured to be turned by hand, around its respective axis.
In accordance with the present application, the connection is made by joining the level material of the roller that is to be provided, directly to the element configured to position of the connecting station, joining being achieved by a clamping, i.e., this element configured to position is configured as a clamp element or clamp roller. Then, after the clamping connection has been established, the position-precise or relatively precise and/or connection-precise or relatively precise alignment of the level material of the connection roller, occurs through turning, for instance, by manually turning of the clamp roller, during the roller exchange.

Further embodiments of the present application are disclosed according to at least one possible embodiment according to the present application. The present application is explained in the following with reference to the drawing figures which are showing the arrangement of one embodiment of the present application. There is shown in:
In the figures reference numeral 1 designates a supply unit that serves for supplying a level material, and in the shown execution form, in one possible embodiment for supplying of a weld-able plastic, or packaging foil 2 that is brought to the packaging machine, not shown. The supply unit 1 has, for this stage of supplying of a weld-able plastic, or packaging foil 2, in a machine frame 3, among other things, two mandrels, or cores, of cylindrical rollers, or the like substantially cylindrically configured structures, which extend with their axes in horizontal direction and parallel or virtually parallel with respect to one another; which rollers 4 and 5 serve in each case for the holding of a roller 6 or 7 (foil roller) of the plastic, or packaging foil 2; and one of these rollers is the roller that is in use for supplying the packaging foil 2, with the packaging machine being in the running condition, and from this roller the foil 2 is drawn off in the direction indicated by the arrow A, and is supplied to the packaging machine; while other roller is serving as an exchange roller, or connection roller, that is held ready for a roller exchange.
The beverage filling machine 105 shown is of a revolving or rotary design, with a rotor 105′, which revolves around a central, vertical machine axis. The rotor 105′ is designed to receive and hold the bottles 130 for filling at a plurality of filling positions 113 located about the periphery of the rotor 105′. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume or amount of liquid beverage into the interior of the bottles 130 to a predetermined or desired level.
The filling arrangements 114 receive the liquid beverage material from a toroidal or annular vessel 117, in which a supply of liquid beverage material is stored under pressure by a gas. The toroidal vessel 117 is a component, for example, of the revolving rotor 105′. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation. The toroidal vessel 117 is also connected to at least one external reservoir or supply of liquid beverage material by a conduit or supply line. In the embodiment shown in
As well as the more typical filling machines having one toroidal vessel, it is possible that in at least one possible embodiment there could be a second toroidal or annular vessel which contains a second product. In this case, each filling arrangement 114 could be connected by separate connections to each of the two toroidal vessels and have two individually-controllable fluid or control valves, so that in each bottle 130, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.
Downstream of the beverage filling machine 105, in the direction of travel of the bottles 130, there can be a beverage bottle closing arrangement or closing station 106 which closes or caps the bottles 130. The beverage bottle closing arrangement or closing station 106 can be connected by a third conveyor arrangement 107 to a beverage bottle labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of starwheels, or may also include a linear conveyor device.
In the illustrated embodiment, the beverage bottle labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to bottles 130. In the embodiment shown, the labeling arrangement 108 has three output conveyor arrangement: a first output conveyor arrangement 109, a second output conveyor arrangement 110, and a third output conveyor arrangement 111, all of which convey filled, closed, and labeled bottles 130 to different locations.
The first output conveyor arrangement 109, in the embodiment shown, is designed to convey bottles 130 that are filled with a first type of liquid beverage supplied by, for example, the supply reservoir 123. The second output conveyor arrangement 110, in the embodiment shown, is designed to convey bottles 130 that are filled with a second type of liquid beverage supplied by, for example, the supply reservoir 124. The third output conveyor arrangement 111, in the embodiment shown, is designed to convey incorrectly labeled bottles 130. To further explain, the labeling arrangement 108 can comprise at least one beverage bottle inspection or monitoring device that inspects or monitors the location of labels on the bottles 130 to determine if the labels have been correctly placed or aligned on the bottles 130. The third output conveyor arrangement 111 removes any bottles 130 which have been incorrectly labeled as determined by the inspecting device.
The beverage bottling plant can be controlled by a central control arrangement 112, which could be, for example, computerized control system that monitors and controls the operation of the various stations and mechanisms of the beverage bottling plant.
In general, the turn roller 8 is assigned to the mandrel 4, and the turn roller 9 is assigned to the mandrel 5. The two turn rollers 10 form, together with another roller 13, an assembly or equipment structure 14, that is in one possible embodiment configured for the controlled change, or substantially alleviation, or substantially elimination of the tension acting upon the foil during the roller exchange. For this, this foil 2 is passed over three rollers 10 and 13. The roller 13 is at its two ends in each case attached to a swing, or swivel arm, or crank structure, that is generally identified by reference numeral 13.1, and upon this crank structure 13.1, there acts an actuator arrangement and/or a piston-cylinder arrangement, 13.2, so as to effect a controlled swinging of the swivel arm 13.1, and, with it, of the roller 13. The roller 13 is used in conjunction with the foil clamp equipment for the foil [2], and also for the accurate positioning of an image imprinted on the foil.
Another component of the welding station 12 is a clamp roller 15; this clamp roller 15 being configured in such a way that it can be journaled with its respective ends within the frame 11, and the clamp roller 15 is, furthermore, configured to provide a clamp slit 16, namely, in the shown execution embodiment, thereby that the clamp roller 15 is configured in two parts, at least for the extent of its length that is desired for the functioning of welding of the welding station 12, with the two parts being disposed on the respective sides of the clamp slit to 16, the two parts being generally identified by reference numerals 15.1 and 15.2, which are moveable, for clamping, in each case, of a foil beginning, or leading portion, mutually with respect to one another. The turning of the clamp roller 15 and, if desired, also the opening and fastenings of the clamp fissure 16 occurs, in the shown execution form, by hand with a turn crank; and/or switch crank 17 which is provided at one end of the clamp roller 15.
Components of the station 12 that is providing a weld, are, furthermore, two heat-able welding rails 18 which, firstly, lie with their longitudinal extent substantially parallel to the axis of rotation of the clamp roller 15; secondly, are disposed in offset manner at an angle somewhat smaller than one hundred eighty degrees with respect to this axis of rotation; as well as, thirdly, are moveable by actuator elements (e.g., pneumatic piston-cylinder arrangements) in controlled manner in the direction toward the clamp roller 15, and in the direction away from the clamp roller 15.
For a roller exchange, for instance, of the roller 7 by the roller 6, in the
The connecting of the foil beginning to the clamp roller 15 occurs, furthermore, in such a way that during the roller exchange, the connection of the foils is substantially such that the sides match. For this, in the shown embodiment form, i.e., the clamp roller 15 is turned in such a way that upon fastening of the foils with the shown execution form, on fastening the foil beginning, that the direction of rotation that is indicated by the arrow B, is opposed, at the circumferential area of the clamp roller 15, which area is adneighboring the foil that is being used, to the direction of movement, indicated by the direction of the arrow A, of the used foil.
In order so as to essentially ensure or promote a transition-correct and/or print format-correct connecting of the foil during the roller exchange, an alignment rail, or alignment arrangement 19 is provided which is oriented with its longitudinal extent, parallel or virtually parallel to the central axis of the clamp roller 15, and the alignment rail has a length which applies along, or is in conformity with, the entire foil width. At this alignment rail 19, the foil 2 that is held in the condition of being ready for a roller exchange, of roller 6, is precisely aligned or generally aligned with respect to marks provided at the foil, for instance, pressure brands, or pressure regions 2.1.
The alignment of the foil at the alignment rail occurs in such a way that the mark applied on the foil (pressure mark, or pressure point, or region), is aligned at the alignment rail [19]. This occurs, for instance, by hand through the operator; and whereby he moves this foil portion into the clamp fissure of the clamp roller in forward movement and/or backward movement.
Alignment of the wrapping material (foil, shrink wrap, polyethylene, or other wrapping materials) may be aligned by aligning at least one indicum on material extending from each of the supply rollers. The at least one indicum may be a pattern or a portion of a pattern, indicia, or a magnetic, optical, electrostatic, or other indicum that may be sensed by a sensor. The alignment of the wrapping material may occur, for instance, automatically through a controller; and whereby the controller receives signals from sensors and relays a signal to a servo motor, for example, to rotate the clamp roller and move the wrapping material in the clamp roller in forward movement and/or backward movement. The wrapping material may be moved forward and/or backward an extend necessary to substantially align the at least one indicum on the wrapping material extending from each supply roller.
Upon clamping of the beginning of the foil in the clamp fissure 16, the position-correct and/or connection-correct adjustment occurs for the welding process by way of a rotation, through substantially 360 degrees, of the clamp roller [15] against the direction of movement, or rotation, of the foil roller [7] that is positioned so as to be in use.
Afterwards, the clamp roller 15 is secured in a suitable way against turning, or other undesired movements.
In order that this alignment rail can be used, firstly, while providing a roller onto the mandrel 4; as well as, secondly, while providing a roller onto the mandrel 5, and in order to improve, in one possible embodiment, also the accessibility of the clamp roller 15, the alignment rail 19 is configured so as to be tilt-able.
Upon completion of the steps of alignment and/or clamping of the foil, it can be desired for achievement of a sufficient foil tension, between the roller 6 and the clamp roller 15, to turn the at-ready roller 6 somewhat in the direction corresponding to an increase of the tension of the foil 2, i.e. corresponding to a raising of the tension of the foil.
By way of sensors indicated schematically by reference numeral 20 in
When a computer 21 of the packaging machine, or arrangement, that is linked to the sensor 20 notes the impending depletion of the material on the respective of the roller 6, 7 presently in use, the computer 21 initiates the exchange process of the pertaining rollers.
For this event, firstly, the processing speed of the packaging machine is brought to a stand-still, and, therefore, the removal speed of the foil 2 from the roller 7 is slowed down.
In the end, the full stop of the slower moving foil 2 occurs in response, for example, through the action of the sensor 20, or by another sensor 22, which sensor monitors or senses the presence of available marks on the foil 2, for instance, of the pressure brands or markings 2.1.
Now the foil between the respective spent roller 6, 7 and the packaging machine is clamped, and this clamping action is performed by the clamp rail 14.1. In one possible embodiment of the present application, by an automatic actuation of the actuator arrangement configured to actuate the clamp beams, or rails, and/or piston-cylinder arrangement, this actuator being designated by reference numeral 13.2, and, accordingly, the associated swinging-movement of swing or swivel arm 13.1 and at this disposed turn roller 13, until the mark (pressure brand) of the foil 2 is detected by means of another sensor 20. This is the position in which at the associated welding rail or beam, there is essentially ensured or promoted a transition-correct and/or print format-accurate connecting of the foil 2 of the new foil roller 6 to the foil 2 used until then.
Subsequently there occurs, in controlled manner, by means of the control computer 21, a moving or actuation of the weld rail, beam, and/or dividing rail 18, from the respective commencement position into the welding position, in which by a dividing, or severing, and/or welding process, the connecting of the foil 2 of the foil roller 6, to the foil that is being brought to the packaging machine, is achieved, as well as a severing of the connection, generated by this weld process, from the remainder of the foil of roller 7 occurs.
In order so as to achieve a substantially perfect weld, weld seam, or weld bead, in one possible embodiment, a weld that is also free of tension during the roller exchange, the initially substantially permanent preliminary tension, or pre-tension, of the foil 2 is reduced or eliminated, or substantially alleviated, due to the controlled swinging of the roller 13, in conformity with the actuation of the pneumatic cylinder 13.2, and this swinging movement occurs at least in the area of the weld to be provided.
Upon conclusion of the procedure comprising the steps of severing and welding, there is performed operation of the actuator arrangement 13.2, and/or piston-cylinder arrangement 13.2 for the swing or swivel arm 13.1, together with the turn roller 13, so that the excess of foil material that had been wound about clamp roller 15, that extends between the clamp equipment 14 and the foil roller 6, is rendered taught; and afterwards the clamp equipment 14 is opened. This approach restricts or minimizes a jerky tension, or pressure, upon the fresh weld upon re-starting of the machine.
Completion of the dividing and/or welding, i.e. after an occurred roller exchange, the packaging machine, controlled by the control computer 21, is brought to the operational condition, i.e. running condition, whereby the foil 2 is drawn off now from the roller 6. The roller 7 is taken by hand from the supply unit. Also taken from the supply unit is the remainder of foil that is present at the clamp roller 15, this being achieved by opening of the clamp fissure 16. For the next roller exchange, a new roller 7 is placed upon the mandrel 5, and the beginning of this roller is fastened, by clamping, in the clamp slit 16 in the clamp roller 15 in a manner that is position-precise or relatively precise and connection-precise or relatively precise, and the clamp roller, with the help of the crank 17, is so turned that the foil 2, that is initially placed from above into the clamp slit 16, again surrounds the clamp roller on a majority portion of the roller circumference, at least, however, the circumferential portion that is facing the used foil 2 of the used roller 6, which means that there will be present at least a one-ply of foil 2 surrounding the pertaining circumferential region of the clamp roller [15]; and in addition the foil 2 that is in the at-ready condition is precisely or relatively precisely aligned for transition-correct and/or print format-accurate connecting. The desired foil tension is set, again by turning of the clamp roller 15, if desired, in conjunction with a turning back of the roller 7 that is positioned on the mandrel 5, between this roller and the clamp roller 15.
Upon depletion of the material of the roller 6 disposed on the mandrel 4, a roller exchange occurs in analogous way once more.
For the roller exchange it is also desired, furthermore, that the rollers 6 and 7 are already precisely aligned or relatively precisely aligned on the respective mandrels 4 and 5. This alignment adjustment occurs in such a way that the center lines of the foils are pulled, or drawn, from the rollers 7 or 6, in such a way that the center lines lie in a common plane and vertically with respect to the axes of the mandrels 4 or 5; and, besides, preferentially are also disposed coincidentally with respect to the center line of the product group, or arrangement.
Any one or more of the above described steps for performing a roller exchange may be automated. For example, each of the steps may be automated to provide a completely automated roller exchange process. In another example, the wrapping material extending from each roller is automatically aligned, welded, and cut, Automation of the process may be achieved with one or more controllers, sensors, servos, robots, and other devices as are known in the art, to automatically effectuate a roller exchange.
