Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speed presetting device for a roll ironer that dries laundry after dehydration while pressing it.

A roll ironer is generally known as a device that dehydrates washed items such as sheets, yukatas, pillow covers, etc. and then dries them while pressing them. FIG. 1 illustrates the configuration of this roll ironer, in which a plurality, for example, three cylindrical rolls 11a to 11c are mounted in parallel at intervals. Each of the rolls 11a to 11c has a circumferential surface made of an air-permeable elastic material, and a large number of small holes (not shown) for ventilation are formed in the circumferential surface. And these rolls 11a-1
1c is operated by variable speed and roll drive motors 12 each consisting of an electromagnetic coupling motor, etc.
They are rotationally driven in the same direction via a transmission device (not shown). A guide stand 13 is provided below these rolls 11a to 11c. This guide stand 1
3 has a suitably fixed distance from the rolls 11a to 11c and is composed of a curved surface, and at both ends there are flat plate stands 14a and 14b having approximately the same height as the shafts of the rolls 11a to 11c. integrally formed. Heat generating parts 15a to 15c are provided on the surface of the guide stand 13 facing the rolls 11a to 11c, respectively.
is embedded. That is, by inserting the object 16 that still contains a large amount of moisture after dehydration into the gap between the roll 11a and the guide table 13 from the flat plate 14a, the object 16 can be transferred to the roll 1.
As the parts 1a to 11c rotate, they advance along the guide stand to the flat plate stand 14b. At this time, the items to be washed are pressed and dried by being pressed against the heat generating parts 15a to 15c. Rolls 11a to 11c
The shafts of the rollers 11a to 11c are provided with exhaust ducts 17a to 17c, and water vapor emitted when the laundry 16 is dried passes through small holes in the circumferential surfaces of the rolls 11a to 11c. Enter inside 11c,
The ducts 17a~
It is exhausted through 17c. Since the moisture content of the object to be washed 16 differs depending on its type and dehydration state, the rotational speed of the rolls 11a to 11c is adjusted to maintain a constant drying state. . This can be done by operating the adjustment knob 181 provided on the setting device 18.
It changes the resistance value of the variable resistor in 8.
According to this resistance value, the motor speed controller 19
The voltage supplied to the roll drive motor 12 is changed to control the rotation speed. Further, in order to prevent the object to be washed 16 from wrapping around the rolls 11a to 11c, especially when the rotational speed of the rollers 11a to 11c is high, a tape 20 is provided to restrict the passage of the object to be washed 16. Ru. This tape 20 is connected to the rolls 11a to 11c and the fixed pulley 2.
1a, 21b and a movable pulley 22 that adjusts the tension of this tape 20.
It revolves by the rotations a to 11c.

However, in the case of the roll ironer as described above, since the moisture content varies depending on the type of the item 16 to be washed and the state of dehydration, etc., the above-mentioned knob 181
The rotational speed of the rolls 11a to 11c had to be changed frequently by operating the rollers 11a to 11c. In addition, it is difficult to always keep the items to be washed 16 in the optimal drying state; if the rotation speed is too slow, the items to be washed will deteriorate due to overdrying, and if it is too fast, the items to be washed will be deteriorated due to insufficient drying. It turned out to be a waste and had to be dried again.

This invention was made in view of the above-mentioned circumstances, and includes a roll that rotates to dry and press the laundry while pressing the laundry against a heating element, and a plurality of preset rotational speeds of this roll. a setting device; a means for selecting and setting a rotational speed according to the object to be washed from among the plurality of rotational speeds preset in the setting device; and rotating the roll at the rotational speed selected and set by the means. An object of the present invention is to provide a speed presetting device for a roll ironer that is easy to handle and can set the finish of drying and pressing according to the type and condition of items to be washed by being equipped with drive control means. shall be.

An embodiment of the present invention will be described below with reference to the drawings. The configuration of the roll ironer main body, which includes the rolls 11a to 11c, the roll drive motor 12, the guide stand 13, etc., is the same as that shown in FIG. 1, so its drawing and explanation will be omitted.

FIG. 2 shows a circuit configuration of a speed presetting device for a roll ironer according to an embodiment of the present invention. For example, three sub-setters 31 to 33 are provided. These sub setting devices 31 to 33 are connected to the operation panel 34 of the main setting device 18.
Main setting device 18
Switching between the sub-setting devices 31 to 33 is performed by a changeover switch (not shown) provided on the operation panel 34. Then, the main setting device 18 and the sub setting device 3
1 to 33 are connected to relays AR1 to AR4 which are linked to changeover switches, respectively. This relay AR
For 1 to AR4, one of them is always “on”
This allows any setting device 18, 31 to 33 to be selected by operating a changeover switch.

Next, the operation of the above embodiment will be explained with reference to FIG. First, before starting the operation of the roll ironer, the sub setting devices 31 to 33 select the roll 11 suitable for the type of laundry to be processed.
Preset the rotational speeds of a to 11c. Then, adjust the adjustment knob 181 of the main setting device 18 to the low speed side, set the changeover switch 35 to the main setting device 18, and start operation. Using the adjustment knob 181, the rotation speed is gradually increased to avoid overloading the roll drive motor 12, and when the rotation speed reaches normal operation, the changeover switch 35 is operated to change the sub-setting according to the item 16 to be washed. Select one of the containers 31-33. As described above, the main setting device 18 or the sub setting device 3 can be set by the changeover switch 35.
When any one of 1 to 33 is selected, the motor speed controller 19 rotates the roll drive motor 12 according to the value set in the selected setting device, and rotates the rolls 11a to 11 at the required rotational speed. 11c rotates. Changes in the type and moisture content of the items 16 to be washed can be dealt with simply by switching the changeover switch 35, and the items 16 to be washed can always be pressed in an optimal dry state. can.

As described above, according to the present invention, it is possible to set multiple rotation speeds without making any major improvements to conventional roll ironers, so the ironer can be It is possible to provide a speed presetting device for a roll ironer that can always rotate the roll at a speed suitable for the object to be washed by appropriately changing the set value.
