DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a work holder such as a patch, a label, a seal, an index, etc., which is used by sticking to an object, and a work holder.

[0002]

2. Description of the Related Art For example, it is common practice to punch a hole at the end of a material to file the material (material to be filed). If the material is filed with the punched holes, it is easy to tear from the punched hole to the end of the material. Therefore, a patch is attached around the punched hole to reinforce the punched hole.

As shown in FIG. 8, a patch 3 is generally provided as a holder 1 attached to both sides of a base (base material such as release paper) 2 in a vertical and horizontal direction.
Peel off each sheet before use. In FIG. 9 showing a partial cross-sectional view of the holder 1, the patches 3 on both sides of the base 2 are attached at the same position with the base 2 interposed therebetween, and the holes 3a of each patch 3 are provided.
And the hole 2a of the base 2 communicate with each other.

[0004] Such a holder 1 is manufactured by a manufacturing method as shown in FIG. In FIG. 10, a pair of dies 10
A and 10B are rotatably arranged in the direction of the arrow on both sides of the base 2 on which the sheet 13 serving as a work material is stuck on both sides. Both dies 10A and 10B have a plurality of dies corresponding to the contour of the patch 3. It has an annular blade (not shown). Each mold 1
When the blades 0A and 10B make a cut in the sheet 13, they are synchronously rotated so as to linearly oppose each other across the base 2, so that the patch 3 is formed on the sheet 13 and unnecessary sheets other than the patch 3 are formed. Portion 13 'is peeled from base 2.

In FIG. 10, holes 3a and 2a are formed at predetermined positions of the sheet 13 and the base 2 before cutting by the dies 10A and 10B.
The cut by 10B is set to be performed centering on the holes 3a and 2a. However, the holes 3a and 2a may be formed after cutting.

[0006]

FIG. 11 is a partial sectional view of a manufacturing method as shown in FIG.
Shown in In the state before cutting, the holes 3a are only formed at regular intervals in the sheets 13 on both surfaces of the base 2, and are circularly formed around the holes 3a of the sheet 13 by the annular blades of the dies 10A and 10B. The patch 3 is formed by forming the notch. The cut is a mold 10A,
Since the annular blade of 10B is formed on the sheet 13 in synchronization, the position is indicated by a dashed line.

However, the annular blades of the dies 10A and 10B bite into the base 2 to ensure that the contour of the patch 3 is cut into the sheet 13. Therefore, as shown in a partially enlarged cross-sectional view in FIG. 12, the blade-shaped groove 20 is formed along the contour of the patch 3. Since the blade-shaped groove 20 is opposed at the same position from both sides of the base 2, the base 2 is very thin at the blade-shaped groove 20. Therefore, base 2
When one patch 3 is peeled off from the base, the base 2 is broken in a circular shape along the blade-shaped groove 20, and a problem occurs that the circular portion of the base 2 and the other patch 3 adhere to the back surface of one patch 3 and peel off. It is not easy to remove the patches 3 one by one.

This applies not only to a patch but also to a holder for a workpiece, such as a label, a sticker, or an index, which is attached to both sides of a base.
Therefore, the present invention has been made in view of such a problem, and in a holding body having works adhered to both sides of a base, a work which can cleanly and surely peel off the works one by one from the base. An object of the present invention is to provide a method for manufacturing a holder and a work holder.

[0009]

According to a first aspect of the present invention, there is provided a method of manufacturing a work holder, comprising: attaching a work to both sides of a base; Attaching the work material to both sides of the base, a pair of molds having a blade having a shape corresponding to the contour of the predetermined work, and rotatably disposed on both sides of the base,
Rotate the blades of both molds one and the other so that they bite into the work material, rotate each work material on both sides of the base using the corresponding mold blades to cut the work of the specified shape, and then Unnecessary work material parts other than the work are peeled off from the base while leaving the base on both sides of the base.

[0010] In this manufacturing method, the position where the mold blade bites into the work material on one side and the other is rotated slightly, so that the work material stuck on both sides of the base is cut by the mold blade. The cut lines that form the contour of the work are misaligned between the one work material and the other work material. Therefore, the blade-shaped grooves formed on both sides of the base by the blades of the mold at the time of cutting do not linearly face each other, but are shifted, so that the thickness of the blade-shaped grooves of the base does not become thinner. When the work is peeled off from the base, the base does not peel off together with the work, and the work can be cleanly and surely peeled off from the base one by one.

According to a second aspect of the present invention, there is provided a method for manufacturing a workpiece holder, comprising: attaching a workpiece to both sides of a base; A mold having a blade having a shape corresponding to the contour of a predetermined work, and a mold for assisting the mold with the blade are rotatably arranged on both sides of the base, and the other is disposed downstream of the mold. A mold having a blade having a shape corresponding to the contour of the predetermined workpiece and a mold assisting the bladed mold,
It is arranged rotatably on both sides with the base in between. First, a work of a predetermined shape is cut into one work material by the mold with the blade on the upstream side. The workpiece is cut in a predetermined shape with the other side of the workpiece using a bladed die on the downstream side, and then the unnecessary one and other workpieces other than the workpiece are left while the workpiece is left on both sides of the base. It is characterized in that it is peeled off from the base.

In this manufacturing method, first, a cut is made in one of the work materials with a mold with an upstream blade, and then a cut is made in the other work material with a mold with a downstream blade. At the time of cutting on the downstream side, the cutting is performed by the downstream bladed mold with a slight shift from the cutting position by the upstream bladed mold. For this reason, as a result, as in the case of the first aspect, the cut line forming the contour of the work is shifted from one work material to the other work material without being coincident. Therefore, the thickness of the blade-shaped groove portion of the base does not become thin, and the base does not peel off together with the work when the work is peeled off from the base. And it can peel off reliably.

According to a third aspect of the present invention, there is provided a workpiece holder comprising a base and a workpiece adhered to both sides of the base. It is characterized in that it is affixed to the other work so as to face it with its position shifted slightly. Since this work holder can be formed by the manufacturing method according to the first or second aspect, similarly, it is possible to cleanly and surely peel off the works one by one from the base.

In the present invention, the work is used for stationery such as patches, labels, stickers, indexes, etc.
Or objects (books, notebooks, files, desks, etc.) such as toys such as character seals for animation and video games
All items that can be attached to and used on bags, appliances, etc.). Examples of the work material include an adhesive film, an adhesive sheet, and an adhesive paper, and examples of the base include a release paper.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments. FIG. 1 shows a partial cross-sectional view of the work holder according to the embodiment. The holding body 1 includes a base 2 serving as a base material, and large and small patches 4 and 5 as works adhered to both surfaces of the base 2. The diameter of the patch 4 is larger than the diameter of the patch 5, and the two patches 4, 5 are opposedly positioned on a concentric circle in a state where the holes 4 a, 5 a of the two patches 4, 5 face each other via the hole 2 a of the base 2. ing. The distance d between the contour of the patch 4 and the contour of the patch 5 is about 0.5 to 1.5 mm, depending on the size of the patch.

When the holder 1 is viewed from the patch 4 side, as shown in the partial plan view of FIG.
Although the position of the hole 2a of the base 5 coincides with the position of the hole 2a of the base 2, the outline (cut line) of the patch 4 indicated by the solid line is located outside the outline (cut line) of the patch 5 indicated by the dashed line. The contours are shifted on concentric circles. The production of such a holder 1 is performed in substantially the same manner as the production method shown in FIG. 10, except that the diameter of one of the dies 10A and 10B is larger than the diameter of the other. The difference is that when the large and small blades of both dies cut the sheet 13, the two dies 10A and 10B are synchronously rotated so that the large and small blades face concentric circles. Since the work is a patch here, a through hole is formed together with the base 2 at each predetermined position of both sheets 13 before cutting by the molds 10A and 10B (in the case of FIG. 10) or the mold 10A. ,
After the cut by 10B, a through hole is formed at the center of each patch 4,5.

Sheet 1 serving as a work material on both sides of base 2
3, and through holes are formed in advance at predetermined intervals. FIG. 3 is a partial sectional view showing a state until the through hole is formed. Holes 4a, 5a, 2a are formed in the sheet 13 and the base 2 on both sides of the base 2, and these holes 4a, 5a are formed.
a and 2a communicate in alignment. Next, the mold 10
When the cuts are made by A and 10B, the large and small blades of the mold rotate synchronously, so a large circular blade is formed around the hole 4a of one sheet 13 by a large annular blade, and the other sheet is cut. A small circular notch is formed around the thirteen holes 5a by a small annular blade. As a result, the large patch 4 and the small patch 5 are simultaneously formed on each sheet 13.

Thereafter, the unnecessary sheet portion other than the patches 4 and 5 is peeled off from the base 2 and the base 2 is cut at an appropriate length to obtain a product having the patches 4 and 5 attached to both surfaces of the base 2. The holder 1 is completed. In the above manufacturing method, the blades of the one and the other molds are different in size, so when the blade cuts into the sheet 13, the blades that have cut into the base 2 are at positions shifted from each other (see the dashed line in FIG. 3). Therefore, as shown in the partially enlarged cross-sectional view of FIG. 4, the blade-shaped grooves 21 and 22 formed in the base 2 after the cutting are not linearly opposed to each other, but are shifted. It does not become thin in parts. Therefore, patch 4 or patch 5
When the base 2 is peeled off, the base 2 is not broken along the contour (cut line) of the patch 4 or the patch 5, and the patches 4 and 5 can be peeled off from the base 2 one by one neatly and reliably.

FIG. 5 is a partial plan view of a work holder according to another embodiment, and FIG. 6 is a partial cross-sectional view thereof. This holder 1
Is, for example, a rectangular label 7 of the same size as a workpiece.
Are affixed to both sides of the base 2, and the labels 7 are opposed to each other with a slight displacement with the base 2 interposed therebetween. Also in this case, the outline of one label 7 and the outline of the other label 7 are shifted by about 0.5 to 1.5 mm. Also in this holder 1, since the blade-shaped grooves 23 and 24 formed in the base 2 by the blades of the mold are not linearly opposed but are shifted,
The labels 7 can be peeled off from the base 2 one by one neatly and reliably.

The holder 1 having the label 7 is a mold 1
Both the blades 0A and 10B have the same rectangular shape and are manufactured by rotating one blade and the other blade so that the biting positions of the blades are slightly shifted. Of course, in this case, the step of forming the through hole is unnecessary. The above manufacturing method uses a pair of molds 10A and 10B.
Another manufacturing method will be described with reference to FIG. 7 taking the holder 1 shown in FIGS. 5 and 6 as an example. In this manufacturing method,
On the upstream side (section X) in the advancing direction of the sheet 2 as a work material affixed to both sides of the base 2,
A die (die cut roll) 31 having a blade (a half-cutting blade) having a shape corresponding to the contour of one label 7
A and a mold (anivil roll applied to the die cut roll) 31B that assists the die cut roll 31A are:
A blade (half-cutting blade) having a shape corresponding to the contour of the other label 7 is provided on both sides of the base 2 so as to be rotatable in the direction of the arrow, and on the downstream side (section Y) of the section X. (Die-cut roll) 32A and a die (anivir roll applied to the die-cut roll) 32 that assists the die-cut roll 32A
B are disposed on both sides of the base 2 so as to be rotatable in the arrow direction. Therefore, the die cut rolls 31A, 3A
2A and the anivir rolls 31B and 32B are arranged on the opposite sides in sections X and Y.

The rolls 32A and 32B of section Y
For example, the displacement can be adjusted in the direction of arrow A by operating the handle, and the displacement can also be adjusted in the direction of arrow B by the drive mechanism of the roll. Thus, the rolls 31A, 3
After arranging 2A, 31B, and 32B, first, a label 7 having a predetermined shape is cut into one (here, the lower side) sheet 13 by the die cut roll 31A of the section X, and then the cut position by the die cut roll 31A The sheet 13 on the other side (here, the upper side) is slightly shifted.
Then, the label 7 having a predetermined shape is cut by the die cut roll 32A of the section Y, and then the unnecessary one and the other sheet portions 13 'other than the label 7 are peeled off from the base 2 while leaving the label 7 on both sides of the base 2. . Subsequently, in the section Y, the rolls 32A and 32B may be moved in the directions indicated by arrows A and B to finely adjust the amount of deviation in the sections X and Y.

The manufacturing method shown in FIG. 7 can be applied to a patch. However, in this case, a punching step is provided before section X or after section Y, as in the above-described manufacturing method.

[0023]

As described above, according to the first aspect of the present invention,
According to the described manufacturing method, when cutting for the contour of the work in the work material on both sides of the base, the blades of the two dies are rotated at positions shifted slightly into the work material at one and the other, so that According to the manufacturing method of the second aspect, since the cutting is performed by the downstream bladed mold with a slight shift from the cutting position by the upstream bladed mold, both are formed on the base by the cut. The blade-shaped grooves do not face each other linearly, and the blade-shaped grooves of the base do not become thin. Therefore, it is possible to cleanly and surely peel off the workpieces one by one from the base.

According to the third aspect of the present invention, since the work holder can be manufactured by the manufacturing method of the first or second aspect, similarly, the work can be peeled off one by one from the base in a clean and reliable manner. Can be.
