BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll ironer for drying an article to be washed and dewatered while pressing it.

[0002]

2. Description of the Related Art A roll ironer is generally known as a method for dewatering a washed article such as a sheet, a table cloth, a pillow cover and the like, followed by drying while pressing. FIG. 5 shows an example of a conventionally proposed roll ironer, in which a plurality of, for example, three cylindrical rotating rollers 11a to 11c are arranged in parallel at appropriate intervals. The rotating rollers 11a to 11c are made of a gas-permeable elastic body such as a pad having a peripheral surface, and
Further, a large number of air-permeable small holes are formed in the roll portion. The rotating rollers 11a to 11c are driven and rotated in the same direction by a driving motor 12. A heating device 13 is provided below the rotating rollers 11a to 11c, and the heating device 13 includes the rotating rollers 11a to 11c.
And the rotating rollers 11a to 11c so as to have a certain gap.
Is formed by a curved surface corresponding to the shape of. At one end of the heating device 13, an introduction conveyor 14 is provided at substantially the same height as the shaft portions of the rotating rollers 11 a to 11 c, and at the other end, a flat plate base 15 is provided integrally with the heating device 13. I have.
Curved plate-shaped heating elements 16a to 16c are embedded in curved surfaces of the heating device 13 facing the rotating rollers 11a to 11c, respectively.

The rotating rollers 11a to 11c rotate while being pressed against the heating elements 16a to 16c by their own weight or an air cylinder. That is, after the dewatering, if the article 17 still containing a large amount of water is placed on the introduction conveyor 14, the article 17 is thrown into the gap between the rotating roller 11a and the heating device 13, and then With the rotation of the rotating rollers 11 a to 11 c, the robot advances to the flat plate 15 along the heating device 13. At this time, the article 17 to be washed is pressed against the heating elements 16a to 16c, and is dried and pressed. The shafts of the rotating rollers 11a to 11c are provided with exhaust ducts 1 respectively.
8a to 18c are provided, and water vapor generated when the article to be washed 17 dries is transmitted through the outer peripheral surfaces of the rollers 11a to 11c and is sucked into the inside of the rotating roller, and the ducts 18a to 18c are provided.
exhausted through c. Further, the article 17 to be washed is
1a to 11c to prevent the tape 2
1 is disposed between the rotating rollers 11a to 11c and the article 17 to be washed, and regulates a passage of the article 17 to be washed. The tape 21 is an endless tape. Tens of the tapes are attached to the width of the rotating rollers 11a to 11c, and the tension of the fixed pulleys 22a, 22b and the tape 21 provided above the rotating rollers 11a to 11c is adjusted. Rotating on the tension pulley 23 and the rotating roller 11a.

This tendency is particularly noticeable when the object to be washed is a thick material such as a table cloth or a bedsheet. Further, the tape is pressed against the heating element by a rotating roller provided with an air cylinder or the like, and is slid while being heated to 150 ° C. to 210 ° C., so that the tape is cut when used for several hours to several days.
In such a case, the operation of the roller ironer main body must be interrupted each time, and the tape must be replaced with a new one. During that time, the drying and pressing of the article to be washed must be stopped. In order to eliminate these drawbacks, instead of using a tape, a cylindrical rotating body having a large number of small holes formed in the peripheral surface at each intermediate position of the rotating roller has been used as a method for regulating the passage of the article to be washed. An arrangement in which a blower that performs suction and exhaust is connected to this rotating body is proposed in Japanese Patent Publication No. 3-61480.

[0009]

In the above-mentioned conventional roll ironer, a cylindrical rotating body having a large number of small holes formed in a peripheral surface at each intermediate position of a rotating roller is used to regulate a passage of an object to be washed. The structure in which a blower for performing suction and exhaust is connected to the rotating body has a drawback that the cost of the machine is increased due to the complicated shape. Further, when processing a thin object to be washed, in the case of FIG. 7, streaks due to a gap between the fixed portion between the roll 43 and the gap plate 44 and the rotating portion may be formed. There is a possibility that the object to be washed may be caught between the roller and the roll 42, and there is a case where the finished quality of the object to be washed is deteriorated.
In addition, there are drawbacks that the capacity of the blower is excessive due to the large number of suction portions, and that the suction is localized and adversely affects wrinkles and the like on the article to be washed. SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned conventional drawbacks. A roll ironer that does not have wrinkles or streaks even with a thin object to be washed, is low in manufacturing cost, and can save the capacity load of a suction blower. It is something to offer.

Reference numeral 62a denotes a bearing unit that is installed at a position symmetrical to the drive pulley 63a on the side of the speed reducer 61a and supports the shaft of the drive pulley 63a. The peripheral speed of the rotating roller 11b is also adjusted to substantially the same speed as that of the suction belt 59a.

A suction belt unit 51 is also provided between the outlet of the article 17 to be washed 17 of the rotating roller 11b and the outlet conveyor 33.
A suction belt unit 52 having the same structure as that described above is placed, and a suction belt 59b of this unit 52 is also driven by a drive pulley 63b that is rotated by a drive motor 12 through a V-belt 64b and a speed reducer 61b. The vehicle 17 rotates at a speed substantially equal to the speed (strictly, a high speed of 0.1 to 1%) and delivers the article 17 to the outlet conveyor 33. The peripheral speed of each of the rotating rollers and the feed speed of the suction belt are delicately adjusted so that wrinkles do not cling to the object 17 and do not slip too much when the object 17 is delivered. It is important to adjust to each
The belt pulley uses a variable speed pulley (not shown) at an important point. 53a and 53b are suction belts 51 and 52, respectively.
This is an exhaust pipe for exhausting air from the suction port, and is connected to a suction blower (not shown).

Next, the structure of the suction belt units 51 and 52 will be described with reference to FIGS. 2 to 4. In FIGS. 2 and 4, between the rotating roller 11a and the rotating roller 11b.
A curved box having a large number of punching holes 55a is provided on the upper surface. In this embodiment, the box 55 is a semi-cylindrical box. In addition, a breathable structure (such as heat-resistant, tough, flame-resistant aromatic polyamide fiber,

FIG. 4 shows the distribution of punching holes 55a in the semi-cylindrical portion on the upper surface of the semicircular box 55.
In the range indicated by section A on the rotating roller 11a side, the punching holes 55a are densely distributed, and the range indicated by section B is sparse. That is, when the suction belt 59a passes over the section A, the suction belt 59a exerts a strong suction force on the article 17 to peel off the article 17 from the peripheral surface of the rotating roller 11a, and the section B In the above, the suction force of the suction roller 59a and the semicircular box 55 are reduced by the suction force enough to hold the article 17 lightly, and the article 17 is transferred to the rotating roller 11b. make it easier. The entrance of the second rotating roller 11b in contact with the exit of the semicircular box 55 opens the end of the heating element 16b so as to overlap with the guide 55d of the shaft support plate 55c.
Since the entrance of the second rotating roller 11b is slightly widened, the article 17 to be washed easily enters the entrance of the second rotating roller 11b. The suction belt unit 52 for transferring the article 17 to be washed from the second rotating roller 11b to the outlet conveyor 33 also has a structure similar to the above as shown in FIG.

Next, the operation of the suction belt units 51 and 52 will be described. When the article 17 to be washed, which has been ironed by the first rotating roller 11a, is discharged from the first rotating roller 11a, the article 17 is removed from the first rotating roller 11a by the suction force of the suction belt 59a on the upper surface of the semicircular box 55. It is peeled off and sent to the second rotating roller 11b by the belt 59a. At the outlet of the semicircular box 55, the entry of the second rotating roller 11b is located slightly open, so that the article 17 to be washed can be easily removed from the second rotating roller 11b.
It can be supplied to the b side. The second rotating roller 11
At the outlet b, the article 17 to be washed is delivered to the outlet conveyor 33 by the suction belt 59b having the same configuration. The suction belt 59a is composed of a plurality of belts as shown in FIG.
It can also be handled by books. In this case, the guide portions of the shaft support plate are provided at two places at both ends. The same applies to the case where the number of rotating rollers is three or more.

[0018]

As described in detail above, according to the present invention, the suction holes of the semicircular box of the suction belt unit installed at the transfer section of the linen to be washed are dense on the inlet side and close to the outlet side. Sparsely, that is, since the suction belt is distributed so as to have a strong suction force at the portion in contact with the rotating roller,
The object to be washed is reliably peeled off from the entire surface of the outlet of the rotary roller, and even a thin object to be washed is finished with a high quality iron without wrinkles or streaks. Further, since the shape of the suction belt unit for transfer between the heating devices (between the rotating rollers) may be a simple shape, the machine cost can be reduced. Further, since the suction holes of the semicircular box are densely distributed in a portion requiring a suction force and sparsely distributed in other portions, the capacity load of the suction blower can be reduced. In addition, the entrance of the rotating roller in contact with the exit of the semicircular box was opened at the end of the heating element so as to overlap the guide of the shaft support plate, and the entrance of the rotating roller was slightly widened. This ensures that the tip of the article to be washed is introduced into the rotary roller inlet.
