Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label peeling detecting apparatus, and particularly to a label continuous body in which a plurality of rows of labels are temporarily attached on a band-shaped backing paper, to detect the presence or absence of a peeled label. The present invention relates to a label peeling detection device to be used.

[0002]

2. Description of the Related Art A conventional label printer and a label peeling detecting device will be briefly described with reference to FIGS. FIG. 11 is a schematic side view of a conventional label printer 1. The label printer 1 includes a transfer path 3 for a label continuum 2, a print head 4, a platen 5, and the like.
, A release plate 6, a backing roller 7, a release sensor 8, and a control circuit 9.

[0003] Fig. 12 is a plan view of a label continuum 2 portion. The label continuity 2 is temporarily attached to a band-shaped mount 10 in a plurality of rows (for example, 3 rows) in the width direction on the mount 10. And a plurality of labels 11 formed. After printing the price, the item name, the expiration date, and other predetermined contents on the label 11, the attaching operator peels off the mount 10, and
Labels 1 in the same width direction (three in the upper, middle, and lower directions in the figure)
One set is affixed to a product (not shown) or the like.

[0004] The peeling sensor 8 detects the presence or absence of the label 11 peeled forward in the transport direction due to the turning of the backing sheet 10 at the part of the peeling plate 6. The control circuit 9 drives the print head 4 and the backing roller 7 based on a signal indicating that the label 11 peeled forward has been removed by the sticking operator and the peeling sensor 8 has detected that the label 11 has disappeared. The continuum 2 is transferred and printed, and the next label 11 is peeled off at the peeling plate 6, and is positioned below the peeling sensor 8.

[0005] As shown in FIG.
Since this is detected when all the labels 11 in the set of three have been removed and no longer present, the peeling sensor 8 for detecting the presence or absence of the peeled label 11 is, for example, in a fixed position in the upper row in the figure. If set, mount 10
The label 11 to be finally removed from is controlled by this column. Specifically, label 1 in the upper row in the figure
1 is label 11A, and label 11 in the middle row is label 1
1B and the label 11 in the lower row is a label 11C, a plurality of labels (that is, labels 11A and 11
B, 11C), for example, when the lower row label 11C and the middle row label 11B are peeled off and the label 11A is finally peeled off, the peeling sensor 8 removes the label 11A. This is detected, and the control circuit 9 controls so as to start the next transfer and printing process.

However, in the actual sticking operation, the work efficiency is not always better if the label 11A is not the last one, depending on the dominant hand of the worker, the weakness of the worker, or the relative position or situation where the label printer 1 is arranged. In some cases, if the peeling sensor 8 is fixed to the row of the labels 11 as in the related art, the label 11 to be peeled off and removed at the end is determined, and the label from the backing 10 is determined by the sticking operator. There are various problems, such as difficulty in performing the peeling operation of No. 11 and a decrease in the sticking efficiency.

[0007] Even if the row of the labels 11 on the backing paper 10 is a single row, if the shape of the label 11 is deformable, for example, a round shape, a diamond shape or a star shape, the label 11 is detected by the peeling sensor 8. There is a case where it is difficult to perform the detection properly, and there is a problem that it is difficult to perform the set adjustment when the peeling sensor 8 is fixed as in the related art.

Although there are various types of the peeling sensor 8, there are various problems as described above in any case. For example, FIG. 13 is a schematic perspective view of a reflective peeling sensor 8A such as the peeling sensor 8 shown in FIG. It is in. FIG. 14 is a schematic perspective view of the reflection type peeling sensor 8A, in which the peeling sensor 8A is arranged so that the light emitting portion and the light receiving portion are both on the back side of the label 11. FIG. 15 is a schematic perspective view of a transmission type peeling sensor 8B, in which a light emitting unit and a light receiving unit are separately arranged on the front and back surfaces of a label 11, respectively. FIG. 16 is a schematic perspective view of an inclined transmission type peeling sensor 8C in which the light emitting portion and the light receiving portion are separately arranged on the front and back surfaces of the label 11 and are inclined with respect to the surface of the label 11. I have.

An apparatus for detecting label peeling is disclosed, for example, in Utility Model Registration No. 3015589.

Therefore, when there are a plurality of rows of labels on the backing paper, the efficiency of removing and attaching the labels can be improved by setting the sensor body so that it is easiest to remove the last. . In addition, even if the shape of the label is deformable, for example, round, diamond, or star, the sensor body can be moved to a predetermined position so that the label is properly detected by the sensor body. Thus, it is possible to eliminate the instability of detection due to the shape of the label as in the related art.
