Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label peeling device for peeling a label piece from a mount, and more particularly to a label peeling device capable of preventing a turning member for turning the mount from curving.

(Prior Art) In general, a label continuum has a base material coated with a release agent,
It is a structure in which multiple label pieces coated with adhesive are temporarily attached, and it is used for pricing in retail stores such as supermarkets, and various printing is performed to display code information in factories and various distribution fields. Has been widely used.

A thermal transfer thermal printer will be described as an example of an apparatus for printing on such a label continuum and peeling the label pieces, based on FIG.

The label continuum 1 is formed by continuously temporarily adhering a plurality of label pieces 3 on a strip-shaped mount 2 to which a release agent is applied. The position is detected by the sensor 5 and is sandwiched between the platen 6 and the thermal head 7.
Printing is performed according to a predetermined printing pattern signal applied to the.

The belt-shaped thermal transfer carbon ribbon 8 for this printing is supplied from the supply shaft 9 thereof, and is supplied between the platen 6 and the thermal head 7 together with the label continuum 1 through the sensor 10 in the middle of the passage. It is separated from the label continuum 1 by the separating roller 11 and wound on the winding shaft 12.

In the label continuum 1 after printing is completed, only the backing sheet 2 is turned by the turning pin 13, the label piece 3 is peeled off, and the backing sheet 2 is wound on the winding shaft 14.

A frame 15 for rotatably supporting the platen 6 above and below, as shown in a perspective view in FIG. 2, is enlarged by enlarging the turning pin 13 part around which the mount 2 turns.
A turning pin support frame 16 is fixed to the steering pin, and the turning pin 13 is rotatably attached to the end of the turning pin support frame 16.

However, as shown by the phantom line in FIG. 2, in the case of the label continuum 1 in which the label piece 3 has a wide width,
There is a problem that the center portion of the turning pin 13 is bent due to the resistance from the turning label piece 3, and the peeling action of the label piece 3 cannot be performed smoothly.

(Object of the Invention) The present invention provides a label peeling apparatus that distributes a turning load for label peeling, averages the peeling, and stabilizes the peeling, particularly when a wide label is peeled from a strip-shaped mount. With the goal.

(Summary of the Invention) In the present invention, when the label temporarily attached to the strip-shaped mount is peeled off by the turning means, the turning means is provided with the support pin 41 and a plurality of rotations freely rotatably fitted to the support pin. The support pin 41 is composed of rollers 42, and both ends of the support pin 41 are supported by the rotation support frames 16 and 16, and the support portions 44 of the curving prevention frames 43 and 43 are inserted into the gaps between the rotation rollers 42. This is a structure in which the support portion 44 abuts and supports.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIGS. 3 and 4. The same parts as those shown in FIGS. 1 and 2 of the prior art are designated by the same reference numerals and the detailed description thereof will be omitted.

In FIG. 3, a pair of turning pin supporting frames 16 and 16 are provided with a supporting pin 41 screwed by a nut 40 as a turning member of the strip mount of the label continuum.
The configuration is such that 42 is rotatably loosely fitted.

More specifically, the rotary roller 42 is divided into three parts as shown in the drawing, and the semicircular support portion of the curving prevention frame 43 is provided in the gap between them.
44 is inserted, and the supporting pin 41 is supported in abutment by semicircular supporting portions 44, 44 so as to ensure the rotation of the rotating rollers 42, 42, 42. (See FIG. 4, which is a side view when viewed from the direction of the arrow VI in FIG. 3.) The bending prevention frame 43 is fixed to the turning pin support frame 16 by a nut 45.

According to this structure, the label piece 3 can be easily peeled off due to the rotation of the rotary roller 42, and the support pin 41 can be supported at two points by the pair of support portions 44, so that the bending can be more reliably prevented. It becomes possible. Of course, it is needless to say that if it is configured to support at three or more points, it is possible to cope with the peeling action of a wider label piece.

Further, since the turning of the strip-shaped mount 2, that is, the rotation of the rotary roller 42 associated with the peeling of the label piece 3 and the support for preventing the bending of the support pin 41 by the support portion 44 are completely independent, Free rotation is guaranteed reliably.

In this embodiment, the case where the label piece 3 is printed and peeled off is shown, but it can also be applied to an apparatus that only peels off the label piece by setting the label continuous body which is preprinted and made into a roll shape. Of course.

(Effects of the Invention) As described above, the present invention is used for peeling a label piece temporarily attached to a strip-shaped backing sheet.
And a plurality of rotating rollers in which this support pin is rotatably fitted.
42, and both ends of this support pin 41 are rotated support frame 16
And a curving prevention frame in the gap between the rotating rollers 42.
Since the support part 44 of 43 is inserted and the support pin 41 is abutted and supported by the support part 44, when a wide label piece is peeled by the turning action of the strip-shaped mount, a plurality of rotating rollers are rotated on the support pin. The turning load of the strip-shaped mount is distributed to each rotating roller, the label peeling action is averaged, and the label is peeled in a stable state.
