Field of the Invention The present invention relates to a method for manufacturing a label temporarily attached to a release sheet and an apparatus for manufacturing the label. The present invention relates to a label manufacturing method and a manufacturing apparatus for the label, which are suitable for use in a label sticking apparatus that peels off a sticker and sticks the sticker to an adherend.

(Prior Art) In the conventional label manufacturing method, as shown in FIG. 9, when the label 101 is temporarily attached to the release sheet 103 with the adhesive layer on the back surface thereof, the label 101 is The label base paper is removed by die cutting to form a predetermined shape. Therefore, the trace of the die cut formed on the release sheet 103 and the edge of the die-cut label 101 are located at the same position.

(Problems to be Solved by the Invention) However, as shown in FIG. 9, the pressure-sensitive adhesive layer 105 formed on the back surface of the label has a die cut mark 107 on the release sheet 103.
Into the paper quality portion of the release sheet 103, which is one layer below the release layer formed on the surface of the release sheet 103 and made of, for example, silicon.

Therefore, when loaded in an automatic label sticking machine that peels the labels 101 one by one from the release sheet 103 and automatically attaches them to the adherend, the label 101 is oriented in a normal direction from the release layer of the release sheet 103. The label is not peeled, and sometimes it is wound on a take-up roll from the peeling plate while being temporarily attached to the peeling sheet 103, or is peeled from the peeling sheet in an abnormal direction and is peeled off from the surface of the adherend. It causes troubles such as being stuck.

Therefore, a main object of the present invention is to provide a label continuum capable of peeling a label from a release sheet in a normal direction.

(Means for Solving Problems) One aspect of the present invention is to provide a release sheet with a step of temporarily attaching a label base paper having an adhesive layer formed on its back surface, and to form the label base paper into an appropriate label shape. , The step of die-cutting from one main surface to the other main surface, the step of separating the die-cut label base paper and the release sheet at the interface between the release sheet of the adhesive layer, and the die-cut label edge And a process of temporarily attaching the label and a release sheet different from the release sheet so as to separate the die-cut trace of the label formed on the release sheet, and separating unnecessary portions other than the label in the label base paper from the label. And a step of allowing the label to be produced.

A second aspect of the present invention is a die release of the label base paper sent together with the release sheet and a transporting means for sequentially transferring a laminate in which the label base paper is temporarily attached with an adhesive layer on the back surface thereof, to the release sheet. A label die-cutting means for forming a label of an appropriate shape, a die-cut label, a separating means for separating the release sheet at the interface between the adhesive layer and the release sheet, and an edge of the die-cut label And the label die-cutting mark formed on the release sheet are separated from each other so that the edge of the label and the label die-cutting mark are displaced and the label and the release sheet are temporarily attached again. The label manufacturing apparatus includes a temporary fixing means and a scrap removing means for separating a portion of the label base paper other than the label from the label.

(Operation and Effect of the Invention) According to the present invention, the label on the back surface of the label is separated so that the edge of the die-cut label and the die-cut trace of the label formed on the release sheet do not coincide with each other. A label temporarily attached to a release sheet with an adhesive layer can be manufactured. Therefore, in the produced label, the adhesive of the label does not enter the die-cut mark of the label and stick to it,
The label is peeled off in the normal direction.

The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

(Embodiment) FIG. 1 is a perspective view of a continuous label body manufactured by a manufacturing method as an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view thereof.

The label continuum 10 includes a release sheet 12, and a label 14 is temporarily attached to a release agent layer side main surface of the release sheet 12 with an adhesive layer 16 on the back surface thereof.

The release sheet 12 is formed by coating a release agent such as silicon on the surface of a long-sized base material to form a release layer, and the release layer main surface has, for example, a die roll, with
A die-cutting trace 18 is formed when a label (not shown) different from 14 is die-cut from the label base paper into a predetermined shape.

Then, the front and rear end edges 20a of the label 14 formed in a direction orthogonal to the transfer direction (arrow direction in FIG. 1) that advances for peeling the label 14 and the label 14 formed in a direction parallel to the transfer direction. A label stamp 17 is formed at a position different from the side edge 20b, that is, at a position closer to the center than the outer peripheral edge 20 of the label 14 in this embodiment.

Next, regarding an example of a method for manufacturing the label continuum 10,
A description will be given below based on a typical manufacturing apparatus.

First, a laminate is prepared by temporarily attaching a label base paper 22 which is a base of the label 14 to the release layer side main surface of the release sheet 12 with an adhesive layer 16, and the laminate is wound on a reel 24 and sequentially labeled. It is formed so that it can be sent to the manufacturing process.

Label base paper 22 and release sheet 12 wound around reel 24
Next, the laminated body of and is sent to the step of die-cutting the label.

As a method of die-cutting this label, as shown in FIG. 3, a die roll 26 having an appropriate blade shape formed on its surface is used.
The label is sent to a label cutting device 28 which is a means for cutting the label.

The label laminated body, which is die-cut into a predetermined shape by the label die-cutting device 28, is divided by the die-cutting groove 32 into the label 14 and the scrap 30 as shown in FIG.

However, the die-cutting groove 32 formed by the label die-cutting device 28 digs deeper than the surface of the release layer of the release sheet 12 even with a precise label die-cutting device, and as shown in FIG. A die-cut mark 18 is formed.

The laminated body that is die-cut into a predetermined shape by the label die-cutting device 28 is then subjected to the label base paper 22 and the release sheet 12 described above.
Are sent to the label peeling device 34, which is a means for separating the adhesive layer 16 and the peeling sheet 12 at the interface.

This label peeling re-use device 34 includes a pressure-sensitive adhesive layer 16 and a peeling sheet 12
And a peeling plate 36, which is a means for spacing and at the interface. By the release plate 36, the release sheet 12 sent in the horizontal transfer direction is suddenly folded back and pulled out in the opposite direction, so that the release sheet 12 and the label base paper 22 are separated from each other, and only the label base paper 22 is provided. The rigidity is maintained as it is, and the re-bonding plate 40 is configured to go straight on. Therefore, the distance between the peeling plate 36 and the re-temporarily attaching plate 40 must be shorter than the length of the label 14 in the traveling direction.

Then, the release sheet 12 peeled by the release plate 36
Is taken up by the take-up reel 38.

Next, a label different from the label 14, in this embodiment, a release sheet 13 that supports the label base paper when a label smaller than the label 14 is die-cut is separately prepared, and a re-temporary fixing means is configured. Then, the rewinding reel 42 is loaded, sequentially pulled out, and sent to the re-temporary attachment plate 40. Then, on the re-temporary attachment plate 40, the straight-moving label 14 and the release sheet 13 are temporarily attached, and the sequentially fed labels 14 are temporarily attached to the release sheet 13 to form a label continuum. To be done.

Incidentally, the release sheet 13 has at least the label die cutting mark 18 formed in a direction orthogonal to the traveling direction in which the label 14 advances from the release sheet 13 again, and the end of the label 14 orthogonal to the traveling direction. A separate sheet from the release sheet 12 that supports the label base paper 22 when the label 14 is die-cut is used so that the label 14 and the edge 20a are separated from each other without being aligned with each other.

The laminate in which the release sheet 12 and the label 14 are re-temporarily adhered in this manner is rewound by the take-up reel 42 and wound so as to be loaded into an automatic label sticking device (not shown).

The scrap 30 portion of the die-cut label base paper 22 has a pressing roller 44 in this embodiment, and re-temporarily attaches the label 14 to the release sheet 12 in cooperation with the re-temporary attachment plate 40. It is configured such that 30 pieces of the label are taken up and wound up on the residue removing reel 46, and only the necessary label 14 is re-temporarily attached to the release sheet 12.

However, this scrap removal may be performed by another method, for example, immediately after the label base paper 22 is die-cut into a predetermined shape by the label die-cutting device 28.

Then, as the label and the release sheet manufactured by the above-mentioned examples, for example, those having the following configurations can be mentioned.

5A, 5B and 5C are different from the above-described examples, the label 50 has a plane circular shape and is peeled in a direction intersecting with a traveling direction (arrows in FIGS. 5A to 5C) for peeling. Sheet
The front arcuate part of the die-cut mark 54 of the label 50 formed on the 52
Label 5 intersects the direction of travel of 54a and the die-cut label
It is configured so that it is separated from the arcuate end edge 50a of 0 without matching. That is, the die-cut mark 54 of the label 50 that intersects the traveling direction is located inside the label 50, and the label 54 is temporarily attached to the release sheet 52.

6A, 6B and 6C are modifications of the examples shown in FIGS. 5A to 5C, and the label 60 has a plane elliptical shape and intersects the traveling direction of the die-cut label 60. The arc-shaped edge 60a of the label 60 and the front die-cut mark 64a of the arc-shaped label 60 formed on the release sheet 62 are configured to be spaced apart from each other. That is, inside the label 60,
An arc-shaped die-cut mark 64 of the label is located which intersects the traveling direction.

7A, FIG. 7B and FIG. 7C, the label 70 is different from the above-mentioned example in that the label 70 is a flat triangle, and the die-cut mark 74 of the label 70 formed on the release sheet 72 is also substantially a flat triangle. The linear front end edge 70a of the label 70 that intersects the traveling direction of the label 70 that is formed for the peeling of the label 70 intersects the traveling direction of the label 70 that is formed for the peeling of the label 70. It is configured so as not to intersect the linear portion 70a.

Unlike the example shown in FIG. 1, in the example shown in FIGS. 8, 8B and 8C, the straight front edge 80a of the label 80 which intersects the traveling direction for peeling the label 80 is orthogonal. The release sheet is temporarily attached to the release sheet 82 so that
Of the die-cutting marks 84 of the label 80 formed on the 82, the front end portion 84a intersecting the traveling direction is the straight front end edge 80a of the label 80.
It is configured to be spaced apart from each other.
