Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an abnormality processing device for a roll ironer that dries the washed and dehydrated items while pressing them.

[Conventional technology]

A roll ironer is generally known as a device that presses and dries washed and dehydrated items such as sheets, yukatas, and pillow covers.
FIG. 3 shows the configuration of the roll ironer, in which a plurality of, for example three, cylindrical rotating rollers 11
a to 11c are arranged in parallel at appropriate intervals. The rotating rollers 11a to 11c have a peripheral surface made of a breathable elastic material such as a felt pad, and are further provided with a large number of small holes (not shown) for ventilation. These rotating rollers 11a to 11c are
They are rotated in the same direction by a variable speed roller drive motor 12, which is an electromagnetic coupling motor, via a transmission device (not shown). A heating device 1 is placed below the rotating rollers 11a to 11c.
3 is provided. This heating device 13 has a curved surface corresponding to the shape of the lower part of the rotating rollers 11a to 11c, and has a rotating roller 1 attached to one end thereof.
At almost the same height as the shaft parts 1a to 11c, install the introduction stand 1.
4 and a lead-out stand 15 at the other end of the heating device 1.
It is formed integrally with 3. Curved plate-shaped heating elements 16a to 16c are embedded in each of the curved surfaces of the heating device 13 corresponding to the rotating rollers 11a to 11c. The rotating rollers 11a to 11c rotate while being pressed against the heating elements 16a to 16c by their own weight or by an air cylinder or the like. That is, the object to be washed 17 is transferred to the rotating roller 11 on the introduction table 14.
When the object 17 is thrown into the gap between the heating device 13 and the heating device 13, the object 17 advances to the delivery table 15 along the curved surface of the heating device as the rotating rollers 11a to 11c rotate. At this time, the heating elements 16a to 16 are placed on the item 17 to be washed.
Drying and pressing are carried out by being pressed against the surface. Exhaust ducts 18a to 18c are connected to the shafts of the rotating rollers 11a to 11c, respectively, and the water vapor emitted when the laundry 17 is dried passes through the circumferential surfaces of the rotating rollers 11a to 11c, and is connected to the ducts 18a to 18c. The air is exhausted by a fan (not shown) through 18a to 18c.

In order to prevent the laundry object 17 from wrapping around the rotating rollers 11a to 11c, the rotating rollers 11a to 11c are
A tape 19 is attached between the washing object 11 and the washing object 17 to restrict the passage of the washing object 17. This tape 19 is an endless tape, and the rotating roller 1
More than ten pulleys are attached to the widths of rollers 1a to 11c, and are attached to fixed pulleys 20a to 20c provided above the rotating rollers 11a to 11c and a movable tension pulley 21 for adjusting the tension of the tape 19. The articles 17 to be washed that are connected to each other and rotate as the rotating rollers 11a to 11c rotate, and are about to wrap around the rotating rollers 11a to 11c, are moved to the rotating roller 11a.
- Peel it off from 11c and guide it to the next position.

[Problem that the invention seeks to solve]

However, in the roll ironer as described above, the tape 19 is generally cut within a very short period of time mainly due to friction with the heating device 13. If the tape 19 is cut and there are a large number of them, the item 17 to be washed may
There were many problems with the finished product, such as wrinkles and curling from the edges. In addition, the torn tape 19 wraps around a folding machine called a folder in a later process, causing problems such as damaging the folding machine and preventing the pressed items from being folded correctly.

This invention has been made in view of the above-mentioned circumstances, and provides a roll ironer abnormality processing device for preventing poor finishing of items to be washed and adverse effects on subsequent processes due to tape cutting. The purpose is to provide

[Means and actions for solving problems]

In accordance with the present invention, the cut tape is automatically collected and discarded by a collection unit close to the rotating roll in accordance with a signal from a detection unit that detects cutting of the tape.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show the configuration of a roll ironer abnormality processing device according to the present invention,
The configuration of the roll ironer main body is the same as that shown in FIG. 3, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

FIG. 1A shows the configuration of a detection section for detecting tape cutting. During normal operation of the roll ironer, a detector 32 is fixed below the tension pulley 21 with a bracket 31. This detector 32 is composed of, for example, a proximity switch or a limit switch, and is turned on when the tension pulley 21 falls due to the cutting of the tape 19, as shown in FIG. 1B. is detected and a detection signal is input to the controller 33. The controller 33 determines which of the plurality of tapes 19 is broken based on the input detection signal, and according to the determination result, the second tape 19 is cut.
As shown in the figure, a signal is sent to open the solenoid valve 34. This solenoid valve 34 is provided to operate each air sucker 35 that is provided in opposition to the position where the plurality of tapes 19 pass through the rotating roller 11c.When this solenoid valve 34 is opened, the piping 36 is compressed air through air suction car 3
5, and the cut tape 19 is sucked and discharged to the outside.

Here, when the controller 33 determines that two or more adjacent tapes among the plurality of tapes 19 have broken, an alarm device (not shown) issues an alarm to the roll ironer user. Set it as follows. This is the item to be washed 1
This is to prevent the poor finish shown in step 7, and may issue a warning and temporarily stop the operation.

In the above embodiment, a means of suctioning with compressed air was shown as a method for collecting the cut tape 19, but this is also possible using a roll having many suction holes formed on the periphery or a needle. It is also conceivable to provide rolls wrapped with cloth or the like, and to wind up and remove the cut tape 19 by bringing these rolls close to the rotating roller 11c in accordance with a tape break detection signal.

〔Effect of the invention〕

As described above, according to the present invention, cutting of the tape is detected and the cut tape is automatically collected, and an alarm is issued depending on the cut location and the number of cuts. It is possible to provide a roll ironer abnormality processing device that can prevent damage to a folding machine in a subsequent process.
