[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning paper winding device for cleaning a roll of a copying machine.

[0002]

2. Description of the Related Art Conventionally, a cleaning paper is wound around a shaft by manually stopping an end of the cleaning paper via a double-sided tape, and after winding a predetermined length of cleaning paper on a shaft by a machine, the cleaning paper is wound. Then, fix the shaft manually with a double-sided tape.

[0003]

When the above-described procedure is adopted, the end of the cleaning paper is fixed to the shaft through a double-sided tape by hand, so that it takes a lot of trouble and is inefficient and mass-produced. Can not. For this reason, there has been a problem that the cost is significantly increased.

Accordingly, an object of the present invention is to provide a cleaning paper winding device in which the end of a cleaning paper is fixed to a shaft via a double-sided tape by machining, and the shaft is fixed to the end of the wound cleaning paper via a double-sided tape. It is to provide a mounting device.

In addition, the first end of the shaft supplied from the first supply unit is held in front of the coating device by a free rotation holding unit with a driving unit, and the held shaft is transferred to the starting end winding position of the base paper. A transfer device; a first tape sticking device provided to stick a tape having an adhesive layer on both surfaces to a shaft before being transferred to a winding position while being held by holding means of the first transfer device; A first pressing device provided to press the winding start end of the base paper on the shaft transported by the device, and cutting the base paper when the base paper of the set length is wound on the shaft; A second transfer device provided to hold both ends of the shaft supplied from the second supply device by holding means, and to supply the shaft toward one side of the winding end of the base paper; A second tape attaching device provided to attach a tape having an adhesive layer on both sides to a holding shaft before being transported by the second transport device, and transported by the second transport device to one side of a winding end of the base paper; And a second pressing device provided to press the winding end of the base paper against the shaft.

[0006]

After holding both ends of the shaft supplied from the first supply device by the holding means of the first transfer device, the first tape attaching device attaches a tape between both ends of the outer peripheral surface of the held shaft.

The shaft on which the tape has been pasted is transferred by a first transfer device, and then the winding start end of the base paper is pressed against the shaft by a first pressing device acting in a forward direction, and the base paper is wound on the shaft via the tape. Fix the start end. The pressing device is moved in the retreating direction after the winding start end of the base paper is fixed.

[0008] The holding means of the shaft on which the tape has been attached is driven by the driving means, and the feeding device is operated to wind the fed base paper around the shaft.

At this time, the cleaning liquid is applied to the base paper by the application device.

When the length of the base paper wound around the shaft reaches the set length, the operation of the driving means and the feeding device is stopped, and then the base paper is cut by the cutting device.

During the winding of the base paper, both ends of the shaft supplied from the second supply device are held by holding means of the second transfer device, and the second tape is held between both ends of the outer peripheral surface of the held shaft. The tape is attached by the attaching device.

Then, after the holding shaft is transferred by the second transfer device, the end of the base paper is pressed against the shaft by the second pressing device acting in the forward direction, and the shaft is fixed to the end of the base paper via the tape.
