Next, an automatic label peeling apparatus 20 according to an embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 3 and 4 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a side view of an essential part of the automatic label peeling apparatus 20 and particularly shows a state when the operation is stopped when the winding operation of the mount 8 is stopped.
The automatic label peeling device 20 includes a supply unit 3 for the label continuous body 2, a transfer path 4, a printing unit 5, a peeling unit 6, and a mount winding unit 7 in the same manner as the automatic label peeling device 1 (FIG. 3) described above. ing.
Further, the automatic label peeling apparatus 20 includes a peeling plate 21 as a member corresponding to the peeling plate 12 in the peeling portion 6, and a label tension holding member (label tension holding plate 22) located on the downstream side of the peeling plate 21. , An urging member (winding spring 23) for urging the label tension holding member 22 in the direction of the mount 8, and a label that is positioned above the peeling portion 6 and can press the label continuous body 2 toward the peeling portion 6. And a pressing plate 24.

  The peeling plate 21 is formed in a tapered shape toward the front end portion 21A, the minimum thickness of the front end portion 21A to which the mount 8 turns is set to about 0.5 mm, for example, and the turning angle is made as large as possible. In addition, the degree of floating of the label continuous body 2 can be made as small as possible.

  The label tension holding plate 22 is a plate material having a V-shaped cross section, and has a width wider than the width of the label continuous body 2 (mounting paper 8), and the peeling portion 6 from the peeling portion 6 toward the board winding portion 7 has a width. This is provided on the downstream side, and the winding tension of the mount 8 can be adjusted or held within a predetermined level range according to the winding operation of the mount 8 by the mount winding section 7.

  The winding spring 23 is labeled in a direction away from the transfer path 4 during the winding operation of the mount 8 (in FIG. 1, a direction in which the mount 8 is pushed clockwise around the front end 21A of the release plate 21). The tension holding plate 22 is urged, and the free end 22A of the label tension holding plate 22 is pushed away from the release plate 21 so that the free end 22A and the leading end portion 21A of the release plate 21 and the mount winding portion 7, the mount 8 is urged outward.

FIG. 2 is a side view of the main part of the automatic label peeling apparatus 20 similar to that in FIG. 1, and in particular during the normal operation during which the mount 8 is wound up, that is, the mount 8 is removed by the mount take-up unit 7. In this state, the tension of the mount 8 is increased during winding, and the label tension holding plate 22 is bent so as to approach the peeling plate 21 against the urging force of the winding spring 23.
Referring to FIGS. 1 and 2, the label tension holding plate 22 is removed from the transfer path 4 during the winding operation of the mount 8 by the mount winding portion 7 (in FIG. 1, the mount 8 is removed from the release plate).
