Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention IJ1 (Field of Application of the Invention) The present invention relates to a label peeling device for peeling a label piece from a backing paper, and in particular can prevent bending of a turning member that turns the backing paper. The present invention relates to a label peeling device as described above.

(Prior Art) In general, a continuous label is made up of a plurality of label pieces coated with an adhesive that are temporarily attached to a mount coated with a release agent.
In addition to being used for pricing at retail stores such as supermarkets, they are also widely used in factories and various distribution fields, with various types of printing applied to display code information, etc.

As an example of a device for printing on such a continuous label body and peeling off label pieces, a thermal transfer printer will be described in FIG. 1 as an example.

Label continuum l is coated with 'Aa agent;? A plurality of label pieces 3 are successively temporarily attached on a mount 2 of a shape,
It is paid out from the supply shaft 4 which is held in the form of a roll,
The position is detected by a sensor 5 in the middle of the path, and it is held between a platen 6 and a thermal head 7, and is printed according to a predetermined print pattern signal applied to the thermal head 7.

A band-shaped thermal transfer carbon ribbon 8 for this printing is supplied from its supply shaft 9, passes through a sensor 1O in the middle of the path, and is supplied together with the label continuous body 1 between the platen 6 and the thermal head 7. It is separated from the label continuous body l by a separating roller 11 and wound up on a winding shaft 12.

After printing is completed, only the backing paper 2 of the continuous label body 1 is turned by the turning pin 13, the label piece 3 is peeled off, and the backing paper 2 is wound up on the winding shaft 14.

As shown in the enlarged view of the turning pin 13 that turns the mount 2 within the circle of FIG. 1, and as shown in a perspective view in FIG. The turning pin support frame 16 is fixed, and the turning pin 13 is attached to the end of the supporting frame 16 so that the turning pin 13 can rotate freely.

However, as shown by the imaginary lines in FIG. 2, in the case of a label strip 3 having a wide width or a label continuous body l, the central portion of the turning pin 13 is deflected due to the resistance from the turning label piece 3. There is a problem in that the label piece 3 cannot be peeled off smoothly.

(Object of the Invention) In view of the above-mentioned problems, the present invention is designed to prevent bending of the turning member in order to ensure reliable label lit especially when supplying a wide label continuous body of 21 feet. The object of the present invention is to provide a label peeling device that has the following features.

(Summary of the Invention) That is, the present invention comprises the turning member as a rotatable small-diameter member to reduce the resistance with the mount, and the preventing member for preventing bending of the turning member from being a turning member or a label. This is a label peeling device provided on the opposite side of the continuous body from the surface that comes into contact with the backing paper.

(Example) Next, one embodiment of the present invention will be described based on FIG.

However, the same parts as in FIGS. 1 and 2 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 3 is a view taken in the direction of arrow m corresponding to the part shown enlarged in the circle in FIG. Only the backing paper 2 of the label continuous body 1 that has been printed on the platen 6 is turned and the label piece 3 is
In the figure, arrow A indicates the direction in which the mount 2 is being turned, and arrow B is the direction in which the label piece 3 is being peeled off.

On the downstream side of the turning pin 13, it is fixed to the turning pin support frame 16 by a bending prevention plate 22 or a note 23. This curvature prevention plate 22 has a protruding abutting portion 24 that abuts on a surface 13b opposite to the surface 13a that abuts the turning pin 13 or the mount 2 and peels off the label piece 3. The distance between the contact portion 24 and the surface 13b is set to such an extent as to ensure rotation of the turning pin 13 and to prevent bending of the turning pin 13 in the direction indicated by the arrow.

With this configuration, even if the acting force f moves in the direction of the arrow when the mount 2 is turned and the label piece 3 is peeled off as the continuous label l is transferred, the surface 13b will not come into contact with the protruding contact portion 24. Since the turning pins 13 are in contact with each other, bending of the turning pin 13 is reliably prevented.

Next, Figure 4 is Kibatsu r! In order to make the rotation of the turning pin 13 smoother as the backing paper 2 turns, and to facilitate the peeling action of the label piece 3 from the backing paper 2,
An example in which the turning pin 13 is supported by a ball bearing 30 is shown. Note that the same parts as in FIG. 3 are given the same reference numerals, and detailed description thereof will be omitted.

FIG. 5 also shows a book 9 as a turning member, in which a rotating roller 42 is rotatably loosely fitted to a support pin 41 fixed to a turning pin support frame 16 with a nut 40. This figure shows yet another embodiment of the invention. The rotating roller 42 is divided into three parts as shown in the figure, and a semicircular support part 44 of the anti-bending frame 43 is inserted into the gap between the two parts, and the support pin is inserted to ensure the rotation of the rotating roller 42. 41 (see Fig. 6 which is Fig. 11), this
The pair of anti-bending IE frames 43 are fixed to the turning pin support frame 16 with nuts 45.

With this configuration, the label piece 3 is easily moved by the rotation of the roller 42, and the supporting pin 41
Since it is supported at two points by the pair of supports) and the ν portion 44, it is possible to more reliably prevent the bending. Of course, if it is configured to be supported at three or more points, it goes without saying that it can also handle the peeling action of wider label pieces.

In addition, the rotation of the rotating roller 42 due to the turning of the mount 2, that is, the peeling of the label piece 3, and the rotation of the support pin 41 by the support part 44
The free rotation of the rotary roller 41 is reliably guaranteed, and the label piece 3 is completely independent of the support for preventing curvature of the label piece 3 than in the previous embodiment. ! It is possible to separate.

31 In this example, a case is shown in which the label piece 3 is printed and then peeled off, but the present invention can also be applied to a device that simply sets a pre-printed roll-shaped label continuous body and peels off the label piece. Of course it is possible.

(Effect) That's it! According to the present invention, the turning member is a rotating IIf label, and this turning member is supported from the back side, so that bending can be reliably prevented, especially when peeling a wide label. This makes it possible to prevent the turning member from curving and stabilize the peeling action.
