Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linen developing device for holding and moving one end of washed and dehydrated linen.

[0002]

2. Description of the Related Art After washing linen, such as washed sheets, has been dehydrated, one end of the linen is gripped by a clip, and the clip gripping the linen is guided by a drive rail to rise.
A device such as that shown in FIG. 5 is generally known as a conventional device for self-propelled to a linen transfer location on an inclined clip rail and transferring the linen to a linen spreading conveyor in the next step. In FIG. 5, the linen 4 which has been washed and dehydrated is carried by the linen conveyor 1 and stacked on the table 2. On the other hand, the empty clip 30 is self-propelled on the inclined clip rail 15 and comes to the front of the stopper 20 and is temporarily stopped. The stopper 20 has a function of sending out the clips 30 one by one, and sends out the clips 30 to the drive rail 40 and engages with the chain of the rail 40 to move at a constant speed. When the worker 11 finds one end of the linen 4 from the linen stack 3 on the table 2 and causes the clip 30 to grip the end, the clip 30 will be fixed.
Is gripped and raised, and is transferred to the free clip rail 16 at the upper end of the drive rail 40. And clip 30
While holding the linen 4, it self-propels on the inclined straight clip rail 16 and is stopped by a stopper 20 at the end of the rail 16. In addition, the linen 4 is naturally loosened during climbing and free running. The linen holding clips 30 arranged in front of the stopper 20 are fed one by one to the drive rail 40 'by the feeding function of the stopper 20. The worker 12 causes one of the paired clips 10 of the spreading device 9 to grip the end of the linen 4 adjacent to the end of the linen 4 gripped by the clip 30, and then the clip 30 of the same linen 4. The other end of the clip 10
To the linen and move the tensioning device.
Spread while moving. The emptied clip 30 rises by the drive rail 40 ', is fed to the clip rail 15 at the upper end, and again travels to the stopper 20 on the worker 11 side.

[0003]

When laying out a linen unfolding device using a conventional slanted linear clip rail (a rail on which the clip holding the linen is self-propelled by its own weight) is laid out, the washed linen is gripped on the clip. The distance (the length indicated by L ₁ in FIG. 5) from the position of the worker to the position of the worker who transfers the loosened linen from the clip on the drive rail in the rear stage to the linen clip of the spreading device is Since it becomes long and the layout area becomes large, the building must be widened or the layout of other functions must be cramped. Further, since the clip rail with the inclination of its own weight for returning the empty clip needs two places to change the direction, it is inevitably longer than the clip rail for carrying linen. Therefore, assuming that the inclination of the clip rail is constant, the rising height of the clip in the drive rail in the subsequent stage must be made higher than the rising height of the first-stage clip. The present invention provides a straight line from a starting point to an end point of a clip rail by providing a curved portion centered on a vertical line at two or more positions of an inclined rail on which a clip holding linen travels by its own weight to reverse the rail. It is an object of the present invention to provide a linen unfolding device that can significantly reduce the layout area of a single-row ascending running unit of linen by shortening the distance, and thereby to solve the above conventional problems.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a clip which can be moved by being guided by a rail holds one end of a rectangular linen, and the linen is moved while being hung to move the linen tension conveyor in the next step. In the linen unfolding device to be transferred to, the clip holding the linen is provided with curved portions centering on the vertical line at two or more positions of the inclined rail on which the clip runs with its own weight. This is a means for solving the problem. It is a thing.

[0005]

[Function] Even if a curved part is provided on the rail on which the clip holding the linen runs, the length of the rail is the same as that of the conventional rail, and the linen loosening effect and the role of stock for work are fully fulfilled. At the same time, the distance from the position of the operator who grips the linen to the clip to the position of the operator who spreads the loosened linen and transfers it to the clip of the device is shortened, so that the layout area is reduced. Also, the sloping rail for empty clips is shortened and can be set to the same length as the linen running rail, so if the inclination angle of the clip rail is constant, the clip receiving height and the clip sending height of the two front and rear drive rails can be set. Can be the same.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments of the drawings. FIGS. 1 to 4 show an embodiment of the present invention, and FIG. 1 shows a linen clip running device before a linen spreading device in one embodiment of the present invention. The whole is shown in a perspective view. Since the operation of this traveling device is almost the same as that described in the section of the prior art, parts other than the inclined free rail on which the clip travels are indicated by the same reference numerals as those shown in FIG. .. That is, the linen conveyor 1, the table 2, the accumulated linen 3,
Linen 4, tension expansion device 9, tension expansion clip 10, worker 11, worker 12, stopper 20, clip 30,
The same reference numerals are used for the drive rail 40 (linen mounting side) and the drive rail 40 '(linen removal side). Now 5
Is a clip rail for an empty clip, and 6 is a clip rail on which a clip holding linen runs. The clip rail 6 has an S shape when viewed in the plan view of FIG. FIG. 2 is a perspective view showing the clip 30 and the drive rail 40. The clip block 31 is fitted to the pin 33 attached to the clip body 32 so that it can freely rotate. A biased compression spring 34 is engaged between the clip body 32 and the clip block 31 to move the clip block 31 to the clip body 3.
It is pressed against 2, and the force for constantly gripping the linen 4 is given. If the end of the linen 4 is pushed between the clip block 31 and the clip body 32, the clip block 31 will try to rotate in the closing direction even if the linen 4 is subsequently pulled, so the gripping force becomes excessively strong and the linen 4 can be pulled out. I can't. When removing the linen 4, it can be easily removed by manually pushing the clip block 31 inward. Further, since the four wheels 35 that freely rotate are fitted to the shaft fixed to the clip body 32 on the upper portion of the clip body 32, the clip 30 can freely travel in the clip rail. Further, a tooth portion 32 a that meshes with the drive chain 42 is provided on the upper portion of the clip body 32.

Next, the structure of the drive rail 40 will be described with reference to FIG. 3. Reference numeral 41 is a drive rail frame which is integrated with the U-shaped rail 40. The entrance and the exit of the rail 40 hinder the running of the clip 30. It is an arc that does not exist. A guide rail 43 for the chain 42 is fixed along the inside of the rail 40.
Is a side roller chain having a guide roller for every two links, and is connected endlessly so that the upper part is hooked on the drive sprocket 44 and the guide sprocket 45, and the lower part is hooked on the guide rail 43. The drive sprocket 44 is shown in FIG.
It is driven by the deceleration motor 46 shown in FIG. Further, the drive rail 40 ′ in the subsequent stage has the same structure as the drive rail 40. The stopper 20 has a function of temporarily stopping and holding the clips 30 that freely travel on the clip rails 5 and supplying them to the drive rails 40 one by one, the structure of which is shown in FIG. Reference numeral 24 denotes a shaft, which is attached to the drive rail frame 41 and is rotatably fitted to a bearing provided on the support plate 21 supporting the clip rail 5, and the stopper arm 25 is fixed to the coaxial 24. Stopper pins 22 and 23 are attached to both ends of the arm 25. A support base 27 is fixed to the support plate 21, and a pneumatic actuator 26 is pinned to the support base 27. The actuator 26 pushes and pulls the extension shaft of the stopper pin 22 to move the stopper arm 25. Rotate.

The operation of the empty clip 30 will be described below.
Runs on the clip rail 5 under its own weight and stops 20
The plurality of clips 30 are in contact with each other and stand by upstream of the stopper 20. Now the stopper 2 when the top clip 30 is stopped
The state of 0 is as shown by the chain double-dashed line in FIG. 4, and the pneumatic actuator 26 projects the operating rod, the stopper arm 25 rotates in the direction of arrow F, the stopper pin 22 hits the clip tooth portion 32a, and the clip 30 moves. It is a state in which the traveling of the vehicle is blocked. Next, when the pneumatic actuator 26 is operated and the stopper arm 25 is rotated in the direction of arrow E, the shape shown by the solid line in FIG. 4 is obtained, and only one clip 30 is fed to the drive rail 40. The next clip 30 is stopped by the stopper pin 23, then stopped by the stopper pin 22 by the rotation of the stopper arm 25 in the direction of the arrow F, and returns to the state of the two-dot chain line.

When the stopper 20 is activated by a signal from a control unit (not shown), one clip 30 is supplied to the drive rail 40. Then, the drive rail 40 receiving the clip 30 lowers the clip 30 at a constant speed,
When it comes to the worker 11, the drive rail 40 is automatically stopped by a sensor (not shown). The operator 11 is the base 2
After finding one end of one linen 4 from the linen stack 3 placed on the clip and making it grip the clip 30, a push button switch (not shown) is pushed to drive the rail 40.
To start. The clip 30 holding the linen is lifted by the drive rail 40 and sent to the clip rail 6, and the clip 30 self-propels by its own weight, passes through the S-shaped curve of the clip rail 6, and temporarily stays in front of the stopper 20 at the rear stage. Then, they are sequentially sent to the drive rail 40 '. Clip 3
During the ascent of 0 and the run, the linen 4 is unraveled, twisted, broken and the overlap is removed. Also, during the lowering of the clip 30 received on the drive rail 40 ′, the operator 12 finds a free end adjacent to the gripped end of the hanging linen 4 and attaches it to the linen tensioning device 9. When the clip 30 reaches one of the pair of clips 10 and then reaches the hand of the worker 12, the drive rail 40 ′ is automatically stopped by a sensor (not shown), and the worker 12 holds the linen 4 in the clip 30. When the push button switch (not shown) is pushed and transferred to one clip 10 of the linen spreading device 9, the linen spreading device 9 starts to move and stretches the linen 4 to send it to the next step. On the other hand, clip 3 emptied of linen 4
Drive rail 40 ', which is also started by the same switch as 0
Then, the clip 30 is moved to the clip rail 5, and the clip 30 starts to move toward the stopper 20 of the first stage again.

[0010]

As described above in detail, according to the present invention, the area occupied by the linen disentanglement transfer section of the linen spreading device can be greatly reduced. Further, since the horizontal length of the structural member to which each device is attached is shortened, including the length of the empty clip transfer section, the manufacturing cost can be reduced.
