Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a label with a release paper, and more particularly, to a label with a release paper in which a release notch is formed on the release paper.
[0002]
[Prior art]
In order to release the release paper smoothly, the label with the release paper temporarily attached to the release paper is glued to a part of the pressure-sensitive adhesive layer of the label or formed with cuts in the release paper. . In the conventional label with release paper, as shown in FIG. 7, a cut 1 is formed in a straight line on the release paper 3, and the release paper 3 is curved by curving the label 2 so that the cut 1 is on the mountain side. Is peeled off from the label 2 and the release paper 3 can be easily peeled off.
[0003]
By the way, when printing such a label with release paper, a strip-like label with release paper having cuts formed in advance at predetermined intervals is wound around the supply shaft of the printer. Then, a strip-like 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 the platen roller and the thermal head perform printing with a label with a release paper interposed therebetween.
[0004]
[Problems to be solved by the invention]
However, the conventional label with release paper is wound or curved when guided by a guide roller, the release paper on both sides of the cut is separated to form a gap, and conversely, both sides of the cut overlap. Unevenness may occur in the label with release paper. Since the thermal head and the platen roller of the printing unit perform printing with the label with release paper sandwiched between them, if irregularities occur in the label with release paper, printing failure or damage to the thermal head occurs. For example, when the label with the release paper is recessed, white lines that are not printed are generated as shown in FIG. 8, and conversely, when the label with the release paper becomes convex, the convex portion becomes the thermal head. The thermal head is damaged.
[0005]
Such defects may occur not only when printing with a printer, but also during the manufacturing stage of labels with release paper. The release papers on both sides of the cuts are separated to form gaps, or both sides of the cuts overlap. In other words, defective production of labels with release paper occurred.
[0006]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a label with release paper that does not become uneven in the manufacturing stage, the printing stage, and the like.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a release paper in which a plurality of labels are temporarily attached to a strip-like release paper at a predetermined pitch, and a cut is formed on the release paper to release the release paper from the label. In the attached label, the notch is formed in a straight line along the longitudinal direction of the strip-shaped release paper, and as a dotted uncut portion formed at a pitch narrower than a predetermined pitch on which the label is temporarily attached. and Setsuzan point has the Setsuzanten is characterized in that formed only in a portion corresponding to the printing area of the label.
[0008]
According to the present invention, since the release papers on both sides of the cut are connected by a predetermined dot-like portion, when the label with release paper is conveyed from the supply shaft of the printer to the printing unit, both sides of the cut are separated, Does not overlap. Therefore, since the label with the release paper does not become uneven, even if the label with the release paper is sandwiched between the thermal head and the platen roller and printing is performed, no printing failure or damage to the printing portion occurs. Similarly, manufacturing defects do not occur in the manufacturing stage.
[0009]
Moreover, the release paper connected by the dotted | punctate part can be easily cut away only by curving a label largely, and a label can be easily peeled from a release paper.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a label with release paper according to the present invention will be described in detail with reference to the accompanying drawings.
[0011]
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.
[0012]
A printer 10 shown in FIG. 1 is a device that prints on a 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.
[0013]
A strip-shaped label 18 with release paper is wound around the supply shaft 12 in a roll shape and attached. As shown in FIG. 2, the strip-shaped label 18 with release paper is composed of a release paper 22 and a label 20 formed in a band shape. A release agent such as silicon resin is applied to the surface of the release paper 22, and a label 20 is temporarily attached to this surface.
[0014]
Further, in the release paper 22, cuts 24 are formed in the width direction at intervals of one label 20. This notch 24 is formed leaving a point-like uncut portion (hereinafter referred to as a “cut remaining point”) 24A. The size L1 and the interval L2 of the cut remaining point 24A are set according to the 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.
[0015]
1 is fed from the supply shaft 12 by rotating the platen roller 26 of the printing unit 14 and passes through a plurality of guide rollers 28, 28... To the printing unit 14. Be transported.
[0016]
The printing unit 14 includes a thermal head 30 and a platen roller 26, and prints barcodes, characters, and the like on the label 20 by heating and cooling a heating element (not shown) of the thermal head 30. 1 is a thermal method, a thermal transfer method may be used in which an ink ribbon is supplied between the thermal head 30 and the platen roller 26 to transfer the ink.
[0017]
The cutting device 16 cuts the printed strip-shaped label 18 with release paper every predetermined number. As a result, a label 18 with release paper as shown in FIG. 3A is formed, and a cut 24 having an uncut point 24A is formed on the release paper 22 of each label 18 with release paper. As shown in FIG. 3 (b), the label 18 with release paper is bent with the notch 24 as a mountain side, whereby the cut remaining point 24 A is cut off, and the release paper 22 on the cut 24 side is peeled off from the label 18. The Therefore, the release paper 22 can be easily peeled and the label 18 can be attached to the object.
[0018]
Next, the operation of the release paper-attached label 18 configured as described above will be described.
[0019]
The release paper-attached label 18 fed out from the supply shaft 12 is guided by several guide rollers 28, 28... At this time, the label 18 with release paper guided by the guide roller 28 is slightly curved. For this reason, the conventional label with release paper has a problem that the release papers 22 on both sides of the cut 24 are separated or overlapped. On the other hand, in the label 18 with release paper of the present embodiment, the release papers 22 on both sides of the cut 24 are connected by the remaining cut points 24A, so that both sides of the cut 24 are always kept at a constant interval. That is, since both sides of the notch 24 do not open or overlap, no unevenness occurs in the label 18 with release paper. Accordingly, it is possible to prevent a printing defect such as a white line from occurring when the printing unit 14 performs printing, or damage to the thermal head 30.
[0020]
As described above, in the label 18 with release paper of the present embodiment, the notch 24 having the cut remaining points 24A is formed on the release paper 22, so that the unevenness does not occur. It is possible to print without generating.
[0021]
Similarly, since the label 18 with release paper does not have irregularities, no manufacturing defect occurs in the manufacturing stage.
[0022]
In the above-described embodiment, the release paper-attached label 18 in which the cuts 24 are formed in advance is attached to the supply shaft 12. However, a cutter device (not shown) is provided between the supply shaft 12 and the printing unit 14. You may form the cut | notch 24 with this cutter apparatus. In this case, as the cutter device, for example, a flexible die is used, and a groove corresponding to the remaining cutting point 24A is formed on the blade of the flexible die. Thereby, the notch 24 which has the cutting residual point 24A is formed in the release paper 22, and the effect similar to embodiment mentioned above can be acquired.
[0023]
Further, in the above-described embodiment, printing is performed on the label 18 with release paper formed in a strip shape, but a printer that prints on a single-leaf label separated for each sheet may be used.
[0024]
The direction in which the cuts 24 are formed 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 remaining cut points 24A in the cut 24 at a predetermined interval, it is possible to prevent both sides of the cut 24 from overlapping or opening.
[0025]
Further, the position and number of the remaining cut 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 remaining cut points 24A and 24A may be provided only at both ends in the width direction. Further, as shown in FIG. 5, the cut residual point 24 </ b> A may be formed only in a portion corresponding to the printing area of the label 20.
[0026]
Further, the shape of the cut 24 is not limited to the above-described embodiment, and 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 release paper-attached label 18 is curved. Also in this case, by forming the cut remaining point 24A, it is possible to prevent both sides of the cut 24 from overlapping or opening.
[0027]
【The invention's effect】
As described above, according to the label with the release paper according to the present invention, the both sides of the cut of the release paper are connected by the predetermined dot-like portions, so that the label with the release paper does not generate unevenness. Therefore, no printing failure or damage to the printed part occurs when printing on a label with release paper, and no manufacturing failure occurs when manufacturing a label with release paper.
