No. 4,280,290, for example, which comprises a lower iron on which the laundry is mounted and an upper iron for depressing the upper surface of the lower iron to press finish the laundry.

Conventionally, in this type of prior art device, when a long-sized laundry such as sheets was to be press finished, it was necessary to repeat such operations as one in which at first a part of the sheets was pressed with the upper iron and then the position of the sheets was displaced and set again and after this work, the upper iron was lowered again to press against the sheets.

Accordingly, in the case that this type of laundry was to be press finished with the prior art pressing machine, there occurred some problems that it required a tremendous amount of labor and time.

Additionally, as described above, since it was necessary to lift up or lower the upper iron several times, there could easily occur some troubles that an operator's head or hands were held by accident with the upper iron and got scaled in touch with the upper iron.

In addition, the prior art pressing machine showed a poor working efficiency and also a poor convenience in use when a pressing work for the sheets was started because the operator usually could not move away from the machine and could not perform other works.

Further, this type of prior art pressing machine frequently showed a case in which the upper iron was installed near a position where the operator stood for setting the laundry at the lower iron. Accordingly, the prior art machine sometimes showed a dangerous state in which the operator's head or the like got scaled with the upper iron when the operator set the laundry on the lower iron.

SUMMARY OF INVENTION

In view of some circumstances as found in the prior art pressing machine, this invention has been invented.

In order to resolve the aforesaid problems, this invention provides such technical means as follows.

That is, as shown in FIG. 1 and the like, this invention comprises the lower iron for use in mounting the laundry and the upper iron for depressing an upper surface of the lower iron to press finish the laundry, in which the aforementioned lower iron is formed into a belt conveyor shape with an iron main body for accepting a press pressure of the upper iron, an annular moving cover covering the outer peripheral surface of the iron main body, endless transmittance members integrally formed with the moving cover and formed into an annular shape and transmittance wheels over which the endless transmittance members are applied and wherein there is provided a driving means for rotating the transmittance wheels only by a predetermined length in response to a control signal got from a controller every time the aforementioned upper iron is opened after the pressing operation to transfer the cover in a rearward direction, the laundry is sent by this driving device in a rearward direction together with the moving cover and press finished with the upper iron.

In this invention, although the driving device is usually constituted by a rotating force generating machine such as an electric motor and the like, it may also be applicable that this driving device is constituted under a combination of a cylinder and a device for changing a linear motion of a rod in the cylinder into a rotating motion. The transmittance member is constituted by a belt or a chain, for example and the controller is constituted by a microcomputer and a sequencer. The predetermined length defined in this case is meant practically to be the same one as a width of the iron surface of the upper iron in a forward or rearward direction or a length slightly shorter than that. This value is set for preventing a part not to be pressed in the laundry from being generated when the laundry is sent intermittently and pressed with the upper iron.

Additionally, although the transmittance wheels in this invention are arranged at the front and rear positions of the lower iron, it may also be applicable that they may be provided with a tension wheel, for example. In addition, this invention may also be applicable in such a way as that it is combined with a device for supplying the laundry to the upper surface of the lower iron or the lower iron is formed into a vertical elongated shape as seen from its side surface to cause the laundry to be sucked to the moving cover, for example, then the laundry to be sent from below toward the upper surface of the lower iron and the laundry to be press finished with the upper iron.

In addition, as shown in FIG. 4, in the case of this preferred embodiment, a rear side transmittance wheel 24 of a pair of front and rear transmittance wheels 24 is formed like a gear at both sides of a shaft 241. In addition, the front side transmittance wheel 24 is formed like a roller at both sides of a shaft 242.

Further, as shown in FIGS. 1 and 5 or the like, the moving cover 22 is supported with a plate 4.

Further this invention, as shown in FIG. 1, is provided with the driving device 6 for rotating the transmittance wheels 24 just for the length which is shorter than a width of the iron surface 31 of the upper iron 3 in a forward or rearward direction in this embodiment, in response to a control signal got from the controller 5 every time the aforementioned upper iron 3 is opened after pressing operation and sending the moving cover 22 rearward.

In the case of this embodiment, the controller 5 is formed microcomputer and the driving device 6 is formed motor.

The controller 5 is electrically connected to a sensor 7 (refer to FIG. 4) for use in detecting the number of rotation of the transmittance wheel 24. Then, the controller 5 is constituted in such a way that when the number of rotation of the transmittance wheel 24 reaches up to a set value, it may output a stop signal to the driving device 6. The set value is set to three times of rotation in this preferred embodiment.

Additionally, in the case of this preferred embodiment, the inner side of the lower iron 2 is evacuated with a suction device 8 (refer to FIGS. 1 and 2 or the like) and it is formed in such a way that the laundry 1 can be sucked and adhered to the moving cover 22. This suction device 8 is formed such that its turned-on or turned-off state can be controlled with a foot switch 81 (refer to FIG. 1).

In addition, in FIG. 1, reference numeral 9 denotes a feeder device for receiving the laundry 1 dropped from the rear side of the lower iron 2 and sending it to its recovering location. This feeder device 9 is formed into a belt-conveyor shape with a motor 91 and an endless transferring belt 92 and arranged below the lower iron 2. Further, reference numeral 10 denotes a case for use in collecting the laundry 1. The laundry 1 is sent to the front side of the device with the feeder device 9 and recovered at this case 10.

In addition, the upper iron 3 in this preferred embodiment is formed in such a way that it can be freely lifted up or lowered. As shown in FIGS. 1 and 7 and the like, when a cylinder 11 for the upper iron 3 receives a signal from the controller 5, its rod extends or retracts to lift up or move down the upper iron 3. Additionally, as shown in FIG. 8, the upper iron 3 is formed such that its rear side can be pushed down and turned around a lateral shaft 12 extending in a lateral direction as viewed from the front side of the device. In this figure, reference numeral 13 denotes a cylinder for use in pushing down the rear side of the upper iron 3. As the rod of this cylinder 13 extends, the rear side of the upper iron 3 is pushed down and in turn as the rod is retracted, the rear side is pulled up to cause the upper iron 3 to be arranged in a horizontal state.

Additionally, as shown in FIG. 1 and FIG. 8 and the like, the upper iron 3 has its rear side to which a drain pipe 14 for use in flowing water generated from steam supplied into the upper iron 3 is connected. Steam supplied from a steam supplying pipe 15 (refer to FIGS. 2 and 3) into the upper iron 3 is heat exchanged to cause its temperature to be reduced and its part is changed into cold water. In this invention, this water is drained through the drain pipe 14 by an operation in which the rod in the cylinder 13 extends to cause the rear side of the upper iron 3 to be pushed down.

Subsequently, an action of this invention of the preferred embodiment will be described as follows.

At first, as shown in FIG. 1 and the like, the operator sets one end of the laundry 1 such as the sheets or the like on the upper surface of the lower iron 2 facing to the operator and turns on a switch 16 of the driving device 6 (refer to FIG. 2). In this case, the laundry 1 is sucked against the moving cover 22 by the sucking device 8. When the switch 16 of the driving device 6 is turned on, the motor is driven to cause the laundry 1 to be sent together with the moving cover 22.

Then, when the transmittance wheels 24 rotate by three times, the controller 5 outputs a stopping signal to the motor acting as the driving device 6 and then the motor stops. With this arrangement, the laundry 1 is sent to the rear side only by an amount slightly shorter than a width of the iron surface 31 of the upper iron 3 in this preferred embodiment in its forward or rearward direction.

Subsequently, the rod in the cylinder 11 for the upper iron 3 extends in reference to the signal got from the controller 5. With this arrangement, the laundry 1 is pressed with the upper iron 3 only for a set time. Then, as the set time elapses, a signal is outputted from the controller 5 to a solenoid valve (not shown) and the solenoid valve changes over a flow path of the air. Under this operation, the rod in the cylinder 11 for the upper iron 3 retracts and the upper iron 3 is lifted by 50 mm in this preferred embodiment and moved away from the upper surface of the lower iron 2.

Next, the controller 5 receives the signal indicating a retraction of the rod in the cylinder 11 for the upper iron 3 and outputs a driving signal to the driving device 6. With this operation, the motor acting as the driving device 6 is driven to cause the laundry 1 to be sent together with the moving cover 22.

Then, as the transmittance wheels 24 are rotated by three times, the motor acting as the driving device 6 stops with a signal got from the controller 5 and subsequently the rod in the cylinder 11 for the upper iron 3 extends.

With this operation, the laundry 1 is pressed with the upper iron 3 by a set time only. Then, as the set time elapses, the rod in the cylinder 11 for the upper iron 3 retracts and the upper iron 3 is opened.

This invention in this preferred embodiment causes the laundry 1 to be sent intermittently in a rearward direction only by a little shorter length than a width of the iron surface 31 of the upper iron 3 together with the moving cover 22 and pressed with the upper iron 3 to finish the laundry 1.

As to the above, this invention is preferable to form: a controller 5 being provided with a control part 5a (refer to FIG. 1) outputting to the driving device 6 a signal for rotating the transmittance wheels 24 in a reverse direction to return the laundry 1 forward together with the moving cover 22 when a press finishing is completed and the upper iron 3 is opened. By the above, laundry 1 such as handkerchieves and like, is sent to rearward and pressed by the upper iron 3, and then to be returned to the front side for easy recovery.

Additionally this invention is preferable that the feeder device 9 is formed into a slide-shape inclined down toward the front side.

In addition, in the case of the aforesaid example, although the laundry 1 is sucked against the moving cover 22 with the suction device 8, this invention is not restricted by this arrangement. That is, it may also realized in this invention that the moving cover 22 is formed with a cloth having several needle-like bristles, for example, or the plane fastener is arranged at the moving cover to cause a contact friction between the moving cover 22 and the laundry 1 to be increased.

Additionally, in the case of this invention, it is of course apparent that the upper iron 3 may be formed in such a way that it can be turned in a forward and rearward direction of the device.

At first, as shown in FIG. 15, an operator sets the laundry 1 such as a handkerchief or the like on the upper surface of the lower iron 2 facing to the operator and turns on the switch 16 of the driving device 6. Then, the motor acting as the driving device 6 rotates in a normal direction and the transmittance wheels 24 rotate in a normal direction, resulting in that the laundry 1 is once transmitted onto the iron main body 21 together with the moving cover 22.

Then, as the laundry 1 is press finished with the upper iron 3 and the upper iron 3 is opened, the motor acting as the driving device 6 is rotated in a reverse direction under application of a signal got from the control circuit 17. As a result, the transmittance wheels 24 are rotated in a reverse direction and the laundry 1 is returned back in a forward direction together with the moving cover 22. Its returning position may be a set position or it may be a position where the laundry 1 is dropped from the front end of the lower iron 2 and returned back to be recovered.

In addition, this invention may also be made such that, as shown in FIGS. 17 to 21, a set work auxiliary device 18 for expanding the laundry 1 in a lateral direction and setting it on the moving cover 22 is installed above the lower iron 2 and the front side position of the upper iron 3. In this case, as the laundry 1, there is provided

such the laundry as one in which an operator hardly sets it with both hands of the operator being expanded, for example, a wide laundry such as the sheets and the like.

The set work auxiliary device 18 is formed to be provided with a pair of right and left clampers 18a and a sliding mechanism 18b for sliding the clampers 18a in such a direction as one in which they are moved away from each other.

The clampers 18a are formed in such away that when a photoelectric sensor 18a2, for example, detects an entering of the end part of the laundry 1 between the upper and lower holding pieces 18a1, the rod in the cylinder 18a3 is extended to hold the laundry 1.

Additionally, the sliding mechanism 18b is formed to be provided with a horizontal guide member 18b1 arranged along a lateral direction for guiding the clampers 18a, and a pair of cylinder devices 18b2 arranged horizontally along the lateral direction in the same manner as that of the guide member 18b1. The rod in each of the cylinder devices 18b2 is arranged in opposition to each other and the clampers 18a are connected to the extremity end of each of the rods through a fixing member 19 in such a way that they can be turned around a vertical shaft 20.

The guide member 18b1 and the cylinder devices 18b2 are arranged at a front side supporting frame 41, and there limit switches 32 turned on through an inward rotation of the clampers 18a around the vertical shaft 20 are arranged at the proper positions of right and left ends of the supporting frame 41.

Further, the set work auxiliary device 18 may be one which is formed in such a way that it can be retracted together with the supporting frame 41 under its non-use state by forming the supporting frame 41 in such a way that it can be turned in a rear side upward direction.

Subsequently, an action of this set work auxiliary device 18 will be described as follows.

An operator inserts the right and left ends of the laundry 1, the sheets for example, into a point between the holding pieces 18a1 of each of the clampers 18a under a condition in which the clampers 18a are approached to each other. Then, the optical path of the photoelectric sensors 18a2 is shut off, the rod in the cylinder 18a3 is extended with a signal got from each of the photoelectric sensors 18a2 and the right and left ends of the laundry 1 are held.

Then, a signal got from the cylinder 18a3 is received and the rod in each of the cylinder devices 18b2 is extended. As a result, the clampers 18a are guided by the guide member 18b1 and moved to the side, respectively, so as to expand the laundry 1 in a lateral direction and keep it in tension. Then, as the rod is further extended, the clampers 18a are turned inwardly around the vertical shaft 20 through a resistance force of the tensioned laundry 1 and the limit switches 32 are operated.

With this operation, the driving operation of each of the cylinder devices 18b2 is terminated and simultaneously the rod in the cylinder 18a3 is retracted and fixing of the right and left ends of the laundry 1 is released. As a result, the laundry 1 drops onto the lower iron 2 and is arranged with its right and left portions being expanded.

Further, when the laundry 1 is arranged on the lower iron 2, the rods in the cylinder devices 18b2 are retracted and the clampers 18a are arranged at the front central part of the lower iron 2 under a state in which they are approached to each other.

In addition, as shown in FIG. 22 and FIG. 23, this invention may be applied as one in which a guard member 70 is arranged at the front side of the upper iron 3 so as to prevent the operator's hand or fingers from entering below the upper iron 3. The guard member 70 is formed into a lateral plate, for example, and is arranged over an entire lateral direction of the upper iron 3. The central part of the guard member 70 is fixed to the upper surface of the upper iron 3 with a fixing member 71.

The fixing member 71 is formed by a pair of right and left lateral members 72 extending in a forward or rearward direction and vertical members 73 pivotally arranged at the front side of the lateral members 72. The rear end of the lateral member 72 is pushed against the upper surface of the upper iron 3 with a coil spring 74. In addition, both upper sides of the guard member 70 are pivotally attached to the extremity ends of the supporting members 75. The rear ends of the supporting members 75 are pivotally attached to the right and left columns 76. Additionally, the guard member 70 is resiliently repelled forward with springs 77 arranged inside the supporting members 75. The front side of each of the supporting members 75 is covered with a cover 78. Then, in the case of this invention in this preferred embodiment, a sensor 79 such as a limit switch or the like that is turned on when the operator's hand or fingers contact with the guard member 70 is arranged inside the cover 78. This sensor 79 is electrically connected to the aforementioned controller 5 (the control circuit part 17 in the case of the device of this invention shown in FIG. 14) and is formed in such a way that when the sensor 79 is turned on, the driving operation of the driving device 6 is terminated.

Next, an action of this invention in this preferred embodiment will be described as follows:

At first, when the operator's hand or fingers contact with the guard member 70, the guard member 70 is pushed rearward to cause the sensor 79 to be turned on. Then, the controller 5 receives signal from the sensor 79 and sends a stop signal to the driving device 6 and the driving device 6 stops. With this operation, the operator's hand or fingers are prevented from being held with the upper iron 3.

Subsequently, when the operator's hand or fingers are moved away from the guard member 70, the guard member 70 returns back with a force of the spring 77 and is arranged in a slant form. With this operation, the sensor 79 is turned off, the driving device 6 is started again and the laundry 1 is sent together with the moving cover 22.

Further, motion of the guard member 70 is restricted with the fixing member 71, coil spring 74 and supporting member 75, and the guard member 70 is arranged at a location slightly above the moving cover 22 so as not to be contacted with the moving cover 22 when the moving cover 22 is moved as indicated by a solid line in FIG. 23.

In addition, as shown in FIG. 24, this invention may also be applicable to one in which members 80 for preventing the moving cover 22 from generating any zigzag motion are arranged at both sides of the lower iron 2. The zigzag motion preventing members 80 in this preferred embodiment are formed with rollers.

The rollers acting as the members 80 for preventing the zigzag motion in this preferred embodiment arranged at both front sides of the lower iron 2, inclined in a slant inward direction and faced upward inside the base frame 811. Side edges of the moving cover 22 are frictionally contacted with the peripheral surfaces of the rollers to restrict its lateral motion. As a result, with this arrangement, the laundry 1 is sent straight together with the moving cover 22 and neatly press finished.
