L to lla are rotationally driven in the same direction by a variable speed roller drive motor 12 consisting of an electromagnetic coupling motor via a transmission device (not shown). A heating device 13 is provided below the rotating rollers 111L to llc. This heating device 13 includes the rotating roller 111
Rotating roller llh with a constant gap from 1 to Ila.
It is composed of a curved surface corresponding to the shape of ~Ilc, and an introduction conveyor 14 using a belt 141 is disposed at one end at approximately the same height as the shafts of the rotating rollers 11h~lie, and the other end. A flat plate stand 15 is provided integrally with the heating device 13.Rotating rollers 11h to 11 of the heating device 13
A curved plate-shaped heating element 16 is provided on each curved surface facing the lc.
m to 16e are buried.

The rotating rollers lla to 11'c rotate while being pressed against the heating elements 1.6a to 16c by their own weight or by an air cylinder or the like. That is, when the object to be washed 17 that 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 to be washed 17 is put into the gap between the rotating roller I1m and the heating device 1s, and then advances along the heating device 13 to the flat plate table 15 as the rotating rollers Ila to 1) c rotate.
At this time, the object to be washed 17 is pressed against the heating elements 16a to 16c, so that it is dried and pressed. Exhaust ducts 18 & - 18c are provided on the shafts of the rotating rollers 11a to 11c, respectively, and the water vapor emitted when the laundry 17 is dried is removed from the rotating rollers Ilh.
The object to be washed 17 that passes through the circumferential surface of the . In order to make the condition uniform, the rotational speed of the rotating rollers llh to llc is changed to adjust the time during which the object to be washed 17 is pressed against the heating elements 16h 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, and according to this resistance value, the motor speed controller 20 or the above-mentioned roll drive The rotational speed of the roll drive motor 12 is controlled by changing the voltage supplied to the motor 12. In addition, the item to be washed 1
In order to prevent the rotating rollers lla to Ilc from being wrapped around the rotating rollers 111L to 111L to 111L to 111L to 111L to 111L to llc, Te'-no 2 is used to restrict the passage of the washing to be washed 17.
It is placed between 7 stops. This tape 21 is an endless tape.
It is connected to fixed pulleys 22a and 22b provided above the rotating rollers Ila to Ilc and a tension pulley 23 that adjusts the tension of the tape 20, and rotates according to the rotation of the rotating rollers Ila to Ilc. 〇〇 [Problem to be solved by the invention] However, in the roll ironer as described above, the item to be washed is constantly pressed and dried by the tape, so the finish of the item to be washed is affected. In the process, tape marks are left behind, resulting in a poor quality finish. This tendency is particularly noticeable when the items to be washed are made of thick fabrics such as tablecloths and wrapping cloths. Further, the tape is pressed against the heating element by a rotating roller equipped with an air cylinder or the like for 150 seconds. Since it is slid while being heated to a temperature between 250°C and 250°C, it will break if used for several hours to several days. Then, the operation of the roll ironer 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 halted during that time. In this case, especially if the torn tape gets wrapped around the rotating roll or the folding machine used in the subsequent process, the downtime will be even longer and production efficiency will be extremely low. This invention was made in view of the above circumstances.
To provide a roll ironer whose operation is not hindered by a means for restricting the passage of the articles to be washed, and which can dry and press the articles in good condition.

[Failure to solve the problem]

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 arranged at each intermediate position of the rotating roller, There is a type 'c' in which a prower for suction and exhaust is connected to this rotating body.

[Effect]

When the above-mentioned rotating body and proar are operated by the above-mentioned means, when the roll ironer is in operation, the rotating body attracts the laundry that is about to wrap around the rotating roller and sends it to the next position. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
Since the main constituent parts such as le and the heating device 13 are the same as those shown in FIG.

Then, cylindrical rotating bodies 31a to 31c, each having a large number of small holes formed in its curved surface, are disposed on each convex portion of the heating device 13' at a position where the object to be washed 17 passes through the heating elements 16 to 16c. do. The rotating bodies 31a to 31c are the rotary row 21
1a to 11e, and have exhaust pipes 328 to 32c connected to their shafts, and these exhaust pipes 32a to 32a are further connected to a blower (not shown). This blower is a suction device for sucking and exhausting air through small holes formed in the surfaces of the rotating bodies 31h to 31c when they rotate. Then, the rotating body 31
An output conveyor 33 similar to the introduction conveyor 14 is provided below the passage of the articles 17 to be washed. Further, heaters 34 a and 34 b for heating the rotary bodies 31 & 31 b of the heating device R13 are embedded in the lower part thereof.

Next, the operation of the roll ironer as described above will be explained. First, the object 17 to be washed and dehydrated is introduced onto the conveyor J4 by the rotation of the belt 141, and the object 17 is introduced into the gap between the rotating roller 11& and the heating device 13. . Then, by rotating roller l1m)
The object to be washed 17 that is pressed against the heating element 16& is moved to the rotating body 31m.
Due to the suction force and rotation of , it is introduced into the gap between the next rotating row 211b and the heating device 13 without being wrapped around the rotating row 2111L.

Below, the rotating roller llb, the heating device 13, and the rotating body 31b1
The same operation as above is repeated with the rotating roller Ilc and the heating device 13, and the washed object 17 is finished drying and pressing.
is finally peeled off from the rotating roller llc by a rotating body 31c, placed on a delivery conveyor 33, and sent to the next folding machine or the like. In this case, heaters 34ae and 34b are embedded in the lower part of the rotating bodies 31a and 31b to constantly heat the rotating bodies 31a and 31b.
The object to be washed 17 that has passed through a+16b reaches the next heating elements 16b and 16c without radiating heat at the rotating bodies 31m and 31b. Therefore, the object to be washed 17 is always kept at a high temperature. This allows for highly efficient drying and pressing.

Next, referring to FIG. 2, the configuration of the rotating bodies 31a to 31c will be explained. This figure shows the rotating body 31 in Fig. 1 above.
The rotating bodies 31b and 31c have a similar configuration in this view when viewed from the direction of arrow m. The rotating body 31a has a roll 43 with a large number of notched holes 42 formed on its surface at regular intervals on the outside of the hollow pipe 41, and the position of the roll 43 of this hollow motherboard f41 is For example, a hole 411 is provided for each roll 43. That is,
The blower performs a suction operation at a punched hole in the roll 43 via the exhaust pipe 32a1, the hollow pipe 41, and the hole 411 in the hollow pipe 41. Also,
A semicircular gap plate 44 having the same diameter as the roll 43 is attached to the heating device 13 so as to cover the portion of the hollow/arm ignition 41 to which the roll 43 is not attached.

FIG. 3 is a cross-sectional view of mainly the roller 43 of the rotating body 31& along the line ■--■ in FIG. 2 above.

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 to be washed 17 is separated from the heating element 16h by the rotation of the rotating roll 11& in this part. At 31h, the suction force and rotation of the rotating body 31a lead the heated body 16b to the gap between the heating element 16b and the rotating roller 11b. Since the rotating body 31a itself is heated by the heater 34m provided at its lower part, the temperature of the object 17 to be washed does not drop in the rotating body 31m.

Next, FIG. 4 is a sectional view mainly of the gap plate 44 of the rotating body 31m taken along the line ■--■ in FIG. 2, as described above. The gap plate 44 is the heating element 161L, 16
It is installed integrally with b, and its surface is continuous. Therefore, in this part, the object to be washed 17 is heated by the heating element 16t.
It slides from above h to the heating element 16b via the gap plays 1 and 44.

Figure 5 shows the rotating body 3111 shown in Figures 3 and 4 above.
is a perspective view illustrating the movement of the object 17 to be washed in
It is peeled off from the rotating roller 11a by the suction and sent to the gap between the next rotating roller llb and the heating element 16b. In this case, the object 12 to be washed moves along the gap plate 44, so that it wraps around the rotating body 31 in the same way due to the suction force of the pinching hole 42 of Row/I/43. .

〔Effect of the invention〕

As described above, according to the present invention, a rotating member having suction force is used as a means for regulating the passage of the items to be washed and sending the items to the next process without being wrapped around the rotating roller, without using a tape. Because it uses tape, there is no need to cut or replace the tape, wrap it around the periphery, or leave the item to be washed with a poor finish, and the item to be washed can always be dried and pressed with high quality. In addition, it is possible to provide a roll ironer with a high operating rate.
