DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a roll ironer that dries washed and dehydrated items while pressing them.

[Conventional technology]

A roll ironer is generally known as a device that dehydrates washed items such as sheets, yukatas, pillow covers, etc. and then presses them to dry them. FIG. 6 shows the configuration of the roll ironer, in which a plurality, for example, three cylindrical rotating rollers 11a to 11c are mounted in parallel at appropriate intervals. These rotating rollers 11a to 11c are
The peripheral surface is made of a breathable elastic material such as a felt pad, and a large number of small holes (not shown) for ventilation are formed. This rotating roller 11a~
11c are rotationally driven 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 13 is provided below the rotating rollers 11a to 11c. This heating device 1
3 is composed of a curved surface corresponding to the shape of the rotating rollers 11a to 11c so as to have a constant gap with the rotating rollers 11a to 11c, and has a curved surface at one end that is approximately the same as the shaft portion of the rotating rollers 11a to 11c. At the height, the introduction conveyor 14 with belt 141
is provided, and a flat plate stand 15 is provided integrally with the heating device 13 at the other end. Curved plate-shaped heating elements 16a to 16c are embedded in the 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 by an air cylinder or the like. That is,
When the object 17 to be washed, which still contains a large amount of water after dehydration, is placed on the introduction conveyor 14, the rotation of the belt 141 causes the object 17 to be washed between the rotating roller 11a and the heating device 13. Thereafter, as the rotating rolls 11a to 11c rotate, it advances along the heating device 13 to the flat plate stand 15. At this time, the object to be washed 17 is
Drying and pressing are performed in order to be pressed against 16c. Exhaust ducts 18a to 18 are provided on the shafts of the rotating rollers 11a to 11c, respectively.
c is provided, and the water vapor emitted when the item 17 to be washed is dried passes through the circumferential surfaces of the rotating rollers 11a to 11c, and is sucked from inside through the ducts 18a to 18c by a fan (not shown). Exhausted. Since the moisture content of the object 17 to be washed differs depending on its type and dehydration state, the rotating rollers 11a to 1 are used to uniformly dry the object 17.
The rotational speed of the washing machine 1c is changed to adjust the time during which the object to be washed 17 is pressed against the heating elements 16a to 16c. This is to change the resistance value of a variable resistor in the setting device 19 by operating an adjustment knob 191 provided on the setting device 19. According to this resistance value, the motor speed controller 20 controls the roll drive. The rotational speed of the roller drive motor 12 is controlled by changing the voltage supplied to the motor 12. Moreover, the object 17 to be washed is rotated by the rotating rollers 11a to 1
To prevent it from wrapping around 1c,
A tape 21 is disposed between the rotating rollers 11a to 11c and the object 17 to regulate the passage of the objects 7. This tape 21 is an endless tape, and has a width corresponding to the width of the rotating rollers 11a to 11c.
More than 10 rollers are installed, and the rotating rollers 11a to 1
Fixed pulleys 22a, 22 provided above 1c
b and a tension pulley 23 that adjusts the tension of the tape 20, and rotating rollers 11a to 11c.
It will revolve according to the rotation of .

[Problem that the invention seeks to solve]

However, with the above-mentioned roll ironer, the items to be washed are constantly pressed by the tape while being dried and pressed, resulting in tape marks on the finished items, resulting in poor quality of the finished product. I become confused. This tendency is particularly noticeable when the items to be washed are made of thick fabrics such as tablecloths and wrapping cloths. Also, the tape
Since it is pressed against a heating element by a rotating roller equipped with an air cylinder or the like and is heated to 150°C to 250°C while sliding, it will break if used for several hours to several days. Then, the operation of the roll ironer main body must be interrupted each time, and the tape must be replaced with a new one, and the drying and pressing operations of the items to be washed are stopped during that time. In this case, especially if the torn tape gets wrapped around a rotating roll or a folding machine used in a later process, the stoppage time becomes even longer, resulting in extremely poor production efficiency.

This invention was made in view of the above-mentioned circumstances, and the means for regulating the path through which the washed items pass does not hinder the operation, and the drying and pressing of the washed items can be finished. The purpose is to provide roll ironers in good condition.

[Means for solving problems]

In this invention, instead of using tape to regulate the path through which the items to be washed pass, a cylindrical rotating body with a large number of small holes formed in the circumferential surface is provided at each intermediate position of the rotating roller. A blower that performs suction and exhaust is connected to a rotating body.

[Effect]

When the rotating body and the blower are operated by the above-mentioned means during operation of the roll ironer, the rotating body sucks up the laundry that is about to wrap around the rotating roller and sends it to the next position. be.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows its configuration, and the main components such as the rotating rollers 11a to 11c and the heating device 13 are the same as those shown in FIG. Explanation will be omitted.

Then, cylindrical rotating bodies 31a to 31c having a large number of small holes formed on the circumferential surface are arranged in each of the convex portions of the heating device 13 at positions where the object to be washed 17 passes through the heating elements 16a to 16c. . This rotating body 31a
~31c rotates in the opposite direction to the rotating rollers 11a~11c, and has an exhaust pipe 32a on its shaft.
~32c is connected, and this exhaust pipe 32a~
32c is further connected to a blower (not shown). This blower includes the rotating bodies 31a to 31c.
This is a suction device for suctioning and exhausting air through small holes formed in the circumferential surface of the cylinder when it rotates. Then, at the lower part of the rotating body 31c where the object to be washed 17 passes,
An output conveyor 33 similar to the introduction conveyor 14 is provided. Furthermore, heaters 34a and 34b for heating the rotating bodies 31a and 31b of the heating device 13 are embedded below the rotating bodies 31a and 31b.

Next, the operation of the roll ironer as described above will be explained. First, when the object 17 to be washed and dehydrated is placed on the introduction conveyor 14, the rotation of the belt 141 introduces the object 17 into the gap between the rotating roller 11a and the heating device 13. . After that, the heating element 16 is rotated by the rotating roller 11a.
Due to the suction force and rotation of the rotating body 31a, the object 17 pressed against the rotating body 31a is prevented from wrapping around the rotating roller 11a, and is transferred to the next rotating roller 11b and the heating device 1.
It is introduced into the gap between 3 and 3. The following rotating roller 11b
and heating device 13, rotating body 31b, rotating roller 11
The same operation as above is repeated in c and the heating device 13, and the washed item 17 is finished drying and pressing.
Finally, the rotating roller 11 is rotated by the rotating body 31c.
The paper is peeled off from c, placed on the delivery conveyor 33, and sent to the next folding machine or the like. In this case, the rotating body 31
Heaters 34a, 34b are embedded in the lower parts of the rotating bodies 31a, 31b, and the rotating bodies 31a, 31b are constantly heated. The heat is not dissipated locally but reaches the next heating element 16a, 16b. Therefore, the object to be washed 17 is always kept at a high temperature, so that more efficient drying and pressing can be performed.

Next, according to FIG. 2, the rotating bodies 31a to 31c
The configuration of is explained below. This figure is a view of the rotating body 31a seen from the direction of the arrow in FIG. 1, and the rotating bodies 31b and 31c have the same structure. The rotating body 31a is a roll 4 having a large number of punching holes 42 formed on the surface at regular intervals on the outside of a hollow pipe 41.
For example, the roll 43 is attached to the hollow pipe 41 at the position where the roll 43 is attached.
A hole 411 is provided for each of the three holes. That is, the blower includes an exhaust pipe 32a and a hollow pipe 4.
1 and through the hole 411 of this hollow pipe 41,
A suction operation is performed using the punched holes in the roll 43. In addition, the roll 4 of the hollow pipe 41
A half-moon-shaped gap plate 44 with the same diameter as the roll 43 is attached so as to cover the part where 3 is not attached.
is attached to the heating device 13.

FIG. 3 is a sectional view of the rotating body 31a, mainly the roll 43, taken along the line - in FIG. The ends of the heating elements 16a and 16b are provided so as to be close to the periphery of the roll 42 in which a large number of punched holes 42 are formed, and the object 17 to be washed is separated from the heating element 16a by the rotation of the rotary roller 11a in this part. It reaches the rotating body 31a, and then is guided into the gap between the heating element 16b and the rotating roller 11b by the suction force and rotation of the rotating body 31a. Since the rotating body 31a itself is heated by the heater 34a provided at its lower part, the object 17 to be washed is heated in the rotating body 31a.
The temperature never drops.

Next, FIG. 4 is a cross-sectional view mainly of the gap plate 44 of the rotary body 31a taken along the - line in FIG. 2 as described above. The gap plate 44 is installed integrally with the heating elements 16a and 16c.
Its surface is continuous. Therefore, in this part, the object 17 to be washed slides from above the heat generating element 16a to the heat generating element 16b via the gap plate 44.

FIG. 5 shows the rotating body 31a shown above and in FIG.
A perspective view illustrating the movement of the object 17 to be washed in
The object to be washed 17 is peeled off from the rotating roller 11a by the suction of the punched holes 42 formed in the roll 43, and is then separated from the rotating roller 11b and the heating element 16b.
sent to the gap between In this case, since the object 17 to be washed moves along the gap plate 44, it will not be wrapped around the rotating body 31a due to the suction force of the punched holes 42 of the roll 43.

Then, the above-mentioned operation is carried out by the rotating body 31b,
The same process is carried out in the section 31c.

〔Effect of the invention〕

As described above, according to the present invention, as a means for regulating the passage of the items to be washed and sending the items to the next step without being wrapped around the rotating roller, the rotating member having suction force is used instead of using tape. Because we are using
Replacement by cutting the tape, wrapping around the periphery,
To provide a roll ironer that can consistently finish drying and pressing of washed items with high quality without causing defects in the finish of washed items, and has a high operating rate.
