DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label with release paper, and more particularly, to a label with release paper in which a cut is formed in the release paper.

[0002]

2. Description of the Related Art In a label with a release paper in which the label is temporarily attached to a release paper, in order to smoothly release the release paper, a part of the pressure-sensitive adhesive layer of the label is killed or a cut is formed in the release paper. You are doing. A conventional label with release paper is shown in FIG.
As shown in FIG. 2, a cut 1 is formed in the release paper 3 in a straight line shape, and the label 2 is formed so that the cut 1 is on the mountain side.
Is curved, the release paper 3 is released from the label 2, and the release paper 3 can be easily released.

When printing such a label with release paper, a band-shaped label with release paper having notches formed in advance at predetermined intervals is wound around a supply shaft of the printer. Then, a strip-shaped label with release paper is fed out from the supply shaft, and supplied to the printing unit while being guided by a guide roller. The printing unit includes a platen roller and a thermal head, and performs printing with the label with release paper interposed between the platen roller and the thermal head.

[0004]

However, the conventional label with release paper is curved when wound or guided by a guide roller, and the release paper on both sides of the cut is separated to form a gap, or In some cases, both sides of the cut were overlapped, and the label with release paper was uneven.
Since the thermal head and the platen roller of the printing unit perform printing with the label with release paper interposed therebetween, if the label with release paper has irregularities, printing failure or damage to the thermal head will occur. For example, when the label with the release paper is dented, an unprinted white line is generated as shown in FIG.
When the label with release paper becomes convex, the convex portion collides with the thermal head, and the thermal head is damaged.

[0005] Such a problem may occur not only when printing with a printer, but also during the manufacturing stage of a label with release paper. The release paper on both sides of the cut is separated, and a gap is formed. The production of labels with release paper was defective due to overlapping on both sides.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a label with a release paper which does not become uneven at a manufacturing stage, a printing stage, or the like.

[0007]

In order to achieve the above object, the present invention provides a label with release paper, wherein a cut is formed in a release paper to which the label has been temporarily attached, in order to release the release paper from the label. , Wherein the cut is formed leaving a predetermined point-like portion.

According to the present invention, since the release papers on both sides of the cut are connected to each other by the predetermined point-like portions, when the label with the release paper is conveyed from the supply shaft of the printer to the printing unit, both sides of the cut are formed. Do not separate or overlap.
Therefore, the label with release paper does not become uneven,
Even when the label with release paper is sandwiched between the thermal head and the platen roller for printing, no printing failure or damage to the printing portion occurs. Similarly, no production failure occurs in the production stage.

Further, the release paper connected by the dotted portions can be easily separated simply by bending the label greatly, and the label can be easily released from the release paper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the label with release paper according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view showing a printer for printing on a label with release paper according to the present invention, and FIG. 2 is a perspective view showing a part of a strip-like label with release paper.

The printer 10 shown in FIG. 1 is a device for printing on the strip-shaped label 18 with release paper shown in FIG. 2, and includes a supply shaft 12, a printing unit 14, and a cutting device 16.

A label 18 with a strip of release paper is wound around the supply shaft 12 in a roll shape and mounted. As shown in FIG. 2, the strip-shaped label 18 with release paper includes a strip-shaped release paper 22 and a label 20. Release paper 2
A release agent such as a silicone resin is applied to the surface of No. 2, and a label 20 is temporarily attached to this surface.

Cuts 24 are formed in the release paper 22 in the width direction at intervals of one label 20. The cut 24 is formed leaving a point-shaped uncut portion (hereinafter referred to as a cut-off point) 24A. The size L1 of the uncut point 24A and the interval L2 thereof are set according to various conditions such as the material and thickness of the release paper 22 and the label 20. For example, the size L1 is 0.5 to 1 mm, and the interval L2 is 25 to 25. Set to 30 mm.

The label 18 with release paper attached to the supply shaft 12 shown in FIG. 1 is fed out from the supply shaft 12 by rotating a platen roller 26 of the printing unit 14, and is printed via a plurality of guide rollers 28. Transported to the unit 14

The printing section 14 includes a thermal head 30 and a platen roller 26, and heats and cools a heating element (not shown) of the thermal head 30 so as to cool the label 20.
Print barcodes and characters. Although the printing unit 14 in FIG. 1 is a heat-sensitive system, a thermal transfer system in which an ink ribbon is supplied between the thermal head 30 and the platen roller 26 to transfer the ink may be used.

The cutting device 16 cuts the printed strip-shaped label 18 with release paper every predetermined number of sheets. As a result, labels 18 with release paper as shown in FIG. 3A are formed, and cuts 24 having uncut points 24A are formed in the release paper 22 of each label 18 with release paper. As shown in FIG. 3B, the label 18 with the release paper is curved with the notch 24 on the mountain side, so that the uncut point 24 is formed.
A is cut off, and the release paper 22 on the side of the cut 24 is peeled from the label 18. Therefore, the release paper 22 can be easily peeled off, and the label 18 can be attached to the target object.

Next, the operation of the label with release paper 18 configured as described above will be described.

The label 18 with release paper fed from the supply shaft 12 is guided by several guide rollers 28, 28, and is conveyed to the printing unit 14 under tension. At this time, the label 18 with the release paper guided by the guide roller 28 is slightly curved. For this reason, the conventional label with a release paper has a problem that the release papers 22 on both sides of the cutout 24 are separated or overlapped. On the other hand, in the label with release paper 18 of the present embodiment, since the release papers 22 on both sides of the cutout 24 are connected at the uncut point 24A, both sides of the cutout 24 are always kept at a constant interval. That is, since the both sides of the cutout 24 do not open or overlap, the unevenness does not occur on the label 18 with the release paper. Therefore, it is possible to prevent a printing defect such as a white line from occurring when printing is performed by the printing unit 14 and to prevent the thermal head 30 from being damaged.

As described above, in the label 18 with the release paper of the present embodiment, since the notch 24 having the uncut point 24A is formed in the release paper 22, no unevenness occurs, and the printer 1
At 0, printing can be performed without causing printing defects or damage to the printing unit 14.

Similarly, since the label 18 with the release paper does not have irregularities, no production defect occurs at the production stage.

In the above embodiment, the cut 2
4 feeds the label 18 with release paper formed in advance to the supply shaft 12
However, a cutter device (not shown) is provided between the supply shaft 12 and the printing unit 14, and the cutting device 2
4 may be formed. In this case, for example, a flexible die is used as the cutter device, and a groove corresponding to the uncut point 24A is formed on the blade of the flexible die. Thereby, the cut 24 having the uncut point 24A in the release paper 22 is formed.
Is formed, and the same effect as in the above-described embodiment can be obtained.

Further, in the above-described embodiment, printing is performed on the label 18 with a release paper formed in a belt shape, but a printer that prints on a single-leaf label cut off one by one may be used.

The direction in which the cuts 24 are formed is as follows.
The present invention is not limited to the above-described embodiment, and may be formed in the longitudinal direction (pitch direction) of the strip-shaped label 18 with release paper as shown in FIG. Also in this case, by forming the uncut points 24A at predetermined intervals in the notch 24, both sides of the notch 24 can be prevented from overlapping or opening.

Further, the position and the number of the uncut points 24A are not limited to the above-described embodiment. For example, when the width of the strip-shaped label 18 with release paper is small, the uncut points 24A may be provided only at both ends in the width direction. In addition, as shown in FIG. 5, the uncut point 24A may be formed only in a portion corresponding to the print area of the label 20.

The shape of the cut 24 is not limited to the above-described embodiment, but may be a curve. For example, as shown in FIG. 6, when the corrugated cut 24 is formed, the release paper 22 is easily peeled when the label 18 with release paper is curved. Also in this case, the formation of the uncut point 24A can prevent both sides of the cut 24 from overlapping or opening.

[0027]

As described above, according to the label with the release paper according to the present invention, since both sides of the cut of the release paper are connected by the predetermined point-like portions, the label with the release paper may have unevenness. There is no. Therefore, there is no printing failure or damage to the printed portion when printing on the label with release paper, and no production failure occurs when manufacturing the label with release paper.
