[0015]

[Function] [Automatic cleaning device for an adhesive roller according to claim 1]
The cleaning means is moved back and forth in the length direction of the adhesive roller by the driving means. When using an adhesive roller, the cleaning means
By moving in the length direction of the adhesive roller, the object is evacuated to a position where the path of the object to be processed passing between the adhesive rollers is not hindered. The cleaning means cleans the entire working surface of the adhesive roller by moving back and forth in the length direction of the adhesive roller.

When using the automatic cleaning device, the cleaning means is moved to an appropriate position with respect to the adhesive roller, and the wiping tape is pressed against the adhesive roller by the pressing means while the adhesive roller is rotated. At this time, the wiping tape slides on the surface of the rotating adhesive roller, and wipes off dirt such as dust and dust attached to the adhesive roller. After the cleaning of a part of the adhesive roller has been completed in this manner, the pressing of the wiping tape by the pressing means is once released, and the cleaning means is slightly moved in the length direction of the adhesive roller. Do the work. Thereafter, the cleaning means is gradually moved in the length direction of the adhesive roller to clean the entire working surface of the adhesive roller. The wiping tape is fed from the first tape winding means to the second tape winding means in accordance with the condition of dirt attached to the wiping tape or the like. Since the wiping tape is used by being gradually fed out from the first tape winding means to the second tape winding means, it can be used for an extremely large number of cleaning operations. The wipe is disposable and should be replaced with a new wipe when it is finished.

When the wiping tape has been used, the reel as the first tape winding means and the reel as the second tape winding means are removed from the cleaning means. Discard the reel together with the wiping tape, attach the reel as the first tape winding means and the reel as the second tape winding means, respectively, on which a new wiping tape is previously wound, to the cleaning means, and attach the wiping tape to the first tape. It is pulled out from the reel as the winding means and set at a predetermined position, and the end of the wiping tape is fixed to the reel as the second tape winding means.

The automatic cleaning device for the adhesive roller according to the third aspect of the present invention is configured such that the cleaning means is moved in the longitudinal direction of the adhesive roller by the driving means. When the adhesive roller is used, the cleaning unit moves to the length direction of the adhesive roller, and retreats to a position where the path of the object to be processed passing between the adhesive rollers is not obstructed. The cleaning means cleans the entire working surface of the adhesive roller by moving back and forth in the length direction of the adhesive roller.

When the automatic cleaning device is used, the cleaning means is moved to an appropriate position with respect to the adhesive roller, and the tape winding means support is moved closer to the adhesive roller by the driving means while the adhesive roller is rotated. The tape is pressed against an adhesive roller. At this time, the wiping tape slides on the surface of the rotating adhesive roller, and wipes off dirt such as dust and dust attached to the adhesive roller. After the cleaning of a part of the adhesive roller is completed in this way, the wiping tape is temporarily separated from the adhesive roller by moving the tape winding means support in the direction away from the adhesive roller by the driving means, and the cleaning means is adhered. The same cleaning operation is performed with the roller slightly moved in the length direction of the sex roller. Thereafter, the cleaning means is gradually moved in the length direction of the adhesive roller to clean the entire working surface of the adhesive roller. The wiping tape is fed from the first tape winding means to the second tape winding means in accordance with the condition of dirt attached to the wiping tape or the like. Since the wiping tape is used by being gradually fed out from the first tape winding means to the second tape winding means, it can be used for an extremely large number of cleaning operations. The wipe is disposable and should be replaced with a new wipe when it is finished.

When the tape winding means support is brought closer to the adhesive roller by the driving means, the wiping tape is pressed by the adhesive roller by the pressing means.

When the wiping tape has been used, the reel as the first tape winding means and the reel as the second tape winding means are removed from the cleaning means. Discard the reel together with the wiping tape, attach the reel as the first tape winding means and the reel as the second tape winding means, respectively, on which a new wiping tape is previously wound, to the cleaning means, and attach the wiping tape to the first tape. It is pulled out from the reel as the winding means and set at a predetermined position, and the end of the wiping tape is fixed to the reel as the second tape winding means.
