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

[Prior Art] A roll ironer is generally known as a device that dehydrates washed items such as sheets, yukatas, and pillow covers, and then dries them while pressing them. FIG. 5 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 is further provided with a large number of small holes (not shown) for ventilation. 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). At the bottom of these rotating rollers 11a to 11c,
A heating device 13 is provided. This heating device 13
is a certain distance from the rotating rollers 11a to 11c.
It is composed of a curved surface corresponding to the shape of the rotating rollers 11a to 11c so as to have a
An introduction belt 14 using a belt 141 is provided at approximately the same height as the shafts of the rotating rollers 11a to 11c, and a flat plate 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 corresponding to 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. In other words, the item to be washed 1 that still contains a large amount of moisture after dehydration
7 is placed on the introduction conveyor 14, the rotation of the belt 141 throws the object 17 between the rotating roller 11a and the heating device 13, and thereafter, as the rotating rollers 11a to 11c rotate. Then,
Proceed along the heating device 13 to the flat plate stand 15.

A tension pulley 23 that adjusts the tension of the fixed pulleys 22a, 22b and the tape 21 provided above the rotating rollers 11a to 11c, which are installed over ten widths of the rotating rollers 11a to 11c.
It rotates with the rotation of the rotating rollers 11a to 11c, and the laundry 17 that is about to be wrapped around the rotating rollers 11a to 11c is moved to the rotating rollers 11a to 1.
Peel it off from 1c and guide it to the next position.

[Problems to be Solved by the Invention] However, in the roll ironer as described above, the items to be washed are always heated and dried from only one side, so the items to be washed are particularly susceptible to pressure. If the thickness is different in some areas, such as fabric or folded parts, drying may be insufficient, and the surfaces or areas where drying may be insufficient should also be completely dried. This has the disadvantage that the surface of the item to be washed that comes into contact with the heating element is excessively heated and dried, resulting in damage to the fabric.

This invention was made in view of the above-mentioned circumstances, and even if the items to be washed are made of thick fabric or have different thicknesses in some areas, it is possible to maintain uniform drying conditions at all times. The purpose is to provide a roll ironer that does the following.

[Means and effects for solving the problem] This invention provides an auxiliary heating device that heats the surface of the object to be washed that does not come into contact with the heating element at the exit portion of each rotating roll in the path through which the object to be washed passes.
