DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing, as an embodiment, a method and apparatus for removing scraps such as labels.
1 and 2 show a scrap removing device 1 for labels and the like, in which a lower roll 4 and a lower roll 4 are adhered to a release paper 3 with a base paper 2 such as a label for which a base paper is punched. It is pressed by the upper roll 5 and fed out onto the peeling plate 6 through the front edge 6a, and bent downward along the rear edge 6b of the arcuate surface of the rear edge 6b in the transverse direction with respect to the feeding direction,
The release paper tension roll 7 disposed below the rear edge 6b of the release plate 6 is wound about half way and turned upside down, and a label or the like is received on the delivery side with a required distance from the rear edge 6b of the release plate 6. The plate 8 is provided, the plate 8 is bent rearward along a front edge 8a formed in an arcuate surface transverse to the delivery direction, and the lower roll 9 is provided behind the rear edge 8b of the label receiving plate 8 and the like. It is sandwiched by the upper roll 10 and applied with tension to be pulled out, sent out to the rear, and wound on a main body winding roll, for example, although not shown. Similarly, although not shown, a product such as a label that can be peeled off may be completed by cutting and stacking each fixed feed.

By bending the release paper 3 according to the shape of the rear edge 6b of the release plate 6, the blank paper 2 such as the blank label is peeled from the release paper 3, and the blank paper 2 such as the blank label to be peeled is attached to the rear edge of the peel plate 6. When the dust removing tension roll 11 provided above 6b is applied with a required tension and pulling direction, the continuous dust portion 2b of the label or the like is curved toward the roll surface of the dust removing tension roll 11 and upward, Further, at this time, the label body 2a is free from the label residue 2b by being removed,
The label or the like receiving plate 8 is sent as it is away from the scraps 2b of the label or the like, sequentially crosses the space from the front edge thereof, and again passes through the peeling paper tension roll 7 from the front edge thereof.
To the release paper 3 and to be surely adhered to the release paper 3 under the pressing force of the lower roll 9 and the upper roll 10 which are rear feeding parts, and as described above, for example, although not shown,
It is to be wound on the main body winding roll. Of course, as described above, although not shown in the drawing, they may be cut and stacked at regular intervals.

From the front edge to the release paper 3 which travels in the space away from and then returns to the label receiving plate 8 again.

The debris portion 2b such as a label is also sent out by the debris removal tension roll 11 while maintaining a constant tension and direction, and the release paper 3 itself is bent instead of being pulled away from the release paper 3 under tension. As a result, the release paper 3 is separated, so that the separation paper 3 is not subjected to a separation tension, and therefore the scraps 2b of the label or the like is not torn and is wound up via the scrap removal tension roll 11. That is, as shown in FIG.
For example, the portion indicated by M of b is not subjected to peeling tension in a state of being adhered to the release paper 3.

The label receiving plate 8 can be moved back and forth in order to adjust the optimum pressing position and the tension position of the label scrap 2b according to the shape and size of the label main body 2a.

Similarly, the dust removing tension roll 11 can be moved back and forth and vertically as necessary in order to adjust the optimum pressing position and the tension position of the dust portion 2b such as label according to the shape and size of the label main body 2a. . Further, although the scrap removing tension roll 11 in the above-mentioned embodiment is a single unit, it may be in a plurality of stages.

As shown in FIG. 5, the scrap removing tension roll 11 can be replaced with a scrap removing tension plate 12 having an arcuate surface 12a whose trailing edge is transverse to the feeding direction.

In the above description, the term "label or the like" is used instead of "label", in order to include a seal and other equivalent products in addition to the label in the label and the like.
