Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold for cutting, crimping, welding, melting, etc., a pattern of a predetermined shape on a sheet material by using processing means such as heat, pressure, ultrasonic waves, and the like.

[0002]

2. Description of the Related Art Conventionally, there has been a method of performing processing such as forming a pattern of a predetermined shape on a sheet material using a roll-shaped mold material or cutting the sheet material. In the processing method using such a roll-shaped mold, a processing blade of a predetermined shape is applied to the surface of the roll-shaped mold, and while the roll-shaped mold is rotated, the sheet material is introduced in accordance with the rotation. Then, the sheet material is cut or patterned into the shape of the processing blade.

[0003] The processing method using the roll-shaped mold material is to process a fixed area using a flat mold material (working blade). Compared to the method of processing while moving itself in the horizontal direction, the sheet material can be continuously supplied to the roll-shaped mold material, so that continuous processing is possible, and work efficiency is good. It has an advantageous effect.

[0004] However, this roll-shaped mold requires a high level of technology and skill to produce compared to the flat mold, and thus has the disadvantage of high cost. In addition, when a different pattern is applied to the sheet material or when the sheet material is cut, similarly to the flat type, a roll-shaped mold material provided with a processing blade having a new pattern must be produced each time. or,
Not only the change of the pattern but also the same pattern, even if only the processing width (processing area) is different, it is necessary to separately manufacture a mold material corresponding to the width.

As described above, conventionally, it is necessary to prepare a mold material for each type in accordance with the processing area and the type of the pattern, which increases the mold cost and hinders reduction of the unit cost of the product. It was. In addition, since the number of types to be held naturally increases, there has been a problem that a very large number of storage locations must be secured.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and the problem to be solved by the present invention is to change patterns easily and easily, and to provide a variety. An object of the present invention is to provide a mold material that can acquire many patterns and cut shapes even if it is a small type of mold material (mold piece), such as forming abundant patterns, and to reduce the unit cost of the product.

[0007]

In order to solve the above-mentioned problems, the invention according to the first aspect of the present invention employs a mold 10 for processing a sheet material 20 into a predetermined shape.
At 0, a processing blade 11 of the same or different shape is composed of a plurality of disk-shaped or roll-shaped mold pieces 10 provided on a mold surface, and a predetermined shape is formed by combining the disk-shaped or roll-shaped plurality of mold pieces 10. The roll-shaped mold member 100 is characterized in that the processing blade 11 is formed.

That is, a plurality of disk-shaped or roll-shaped mold pieces 10 having the same or different shapes are produced, and these are combined to form one mold material 100.
The processing blade 11 has a predetermined shape, and various different patterns can be formed by exchanging, exchanging, or shifting the mold pieces 10.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A roll-shaped mold according to the present invention will be described with reference to the drawings. FIG. 1 illustrates a roll-shaped mold member 100 according to the first embodiment. Here, for convenience of the following description, as shown in FIG. 2 which is a schematic diagram, a roll-shaped circumferential surface 21 is referred to as a “circumferential surface”, a flat circle 23 is referred to as a “circular plane”, and a roll. The length A from one circular plane to the other circular plane of the shaped mold piece is "width", and the diameter B of the circle is "circle diameter".
And a line C connecting the center of one circular plane and the center of the other circular plane is referred to as “central axis”. In the present invention, “processing” indicates all processing states of the sheet, such as cutting, embossing, pressure bonding, welding, and melting.

The roll-shaped mold 100 of the present invention comprises two or more (three in the figure) mold pieces (10a, 10b, 10).
c) Each of the mold pieces 10 is made of a steel material used for a normal mold material, and the entire shape of the mold piece 10 is formed in a substantially columnar shape. A processing blade 11 for forming a cut pattern or an embossed pattern is formed on the circumferential surface. These mold pieces 10 are formed so as to have the same circular diameter. Then, one mold member 100 is formed by combining the plurality of mold pieces 10 having the same circular diameter so that the central axes thereof are on the same line. As a result, the processing blades (11a, 11b, 11
c) One pattern is formed as a whole by 11.

As described above, the present invention is characterized in that a plurality of mold pieces 10 formed in a disk shape or a roll shape are combined to form a processing blade 11 having one pattern. Therefore, other structures may be formed as long as only these requirements are satisfied. For example,
The diameters of the circles of all the mold pieces 10 may be slightly different depending on purposes such as embossing and cutting. The width of each mold piece 10 may be any shape such as a disk shape or a roll shape, and may be any shape.
The size of the whole 0 is not particularly limited. Furthermore, the number of mold pieces 10 to be used is not limited. In addition, as described below, as shown in FIG. 1, in order to fix the respective mold pieces 10 through the support members 40, and to combine the respective mold pieces 10, a circular cross section is formed at the center axis of each of the mold pieces 10. A structure for convenience such as forming a through hole having the same may be added. The means for fixing the respective mold pieces 10 is not particularly limited. For example, as shown in FIG.
1 may be used for fixing. Of course, the pattern of the processing blade 11 formed on the surface is not particularly limited, and the type of the processing machine using the die 100 is not limited at all. For example, any type of processing machine that processes using a roll-shaped mold such as a press machine, a thermal machine, or an ultrasonic machine can be used. Further, the sheet material to be processed is not particularly limited, such as chemical resin (vinyl, nylon, plastic, etc.), natural or chemical fiber cloth (including nonwoven fabric), leather, paper, and the like.

The mold piece 10 thus formed is
Two or more (in Example 1, three mold pieces (10a, 10a
b, 10c)), a through-hole (not shown) is formed in the center axis of the mold piece 10, and a support member 40 having a diameter substantially the same length as the through-hole is penetrated. It is installed so that the central axis is on a straight line, and is fixed from both sides using fixing members (41a, 41b) 41. Thereby, these mold pieces (10a, 10b, 10c) are fixed to the support member 40 to form the mold material 100. At this time, the circumferential surfaces 21 of all the mold pieces (10a, 10b, 10c) are set to have substantially the same distance from the central axis. However, there is no problem even if the processing is slightly different, such as embossing and cutting. Also in the processing blade 11, there is no problem in providing a slight difference in height between a blade for cutting and a blade or the like for only providing a pattern. For example, when embossing is performed together with cutting, an embossing blade lower than the cutting blade is formed.

The roll-shaped mold member 100 thus produced
Is set on a processing machine that can use a roll mold. And
By rotating the support member 40, the roll-shaped
00 rotates. Accordingly, when the sheet material 20 is introduced into the sheet material, the sheet is processed into the shape of the processing blade 11. For example, a case where the ultrasonic machine 60 is used will be described. As shown in FIG. 3, a horn 61 attached to an ultrasonic transmitter is used.
The roll-shaped member 100 is placed so as to abut the sheet member 20 between the ultrasonic generator 61 and the roll-shaped member 100, and the support member 40 is rotated by the rotating device 62. As a result, the sheet material 20 on which the roll-shaped mold member 100 is rotated and held is melted or blown to form a pattern while being introduced at a speed equivalent to the rotating speed of the roll.

As described above, the present invention can be implemented by replacing the conventional mold material with the roll-shaped mold material 100 according to the present invention by using a processing apparatus which has been conventionally used.

Sheet material 2 using the mold material 100 of the present invention
By processing 0, the following operation is achieved.

First, it is possible to form more patterns with a smaller number of molds than in the conventional case. That is, by combining the mold pieces 10 with different patterns, various different patterns can be formed. For example, as shown in FIG. 4, a mold piece 10d (hereinafter simply referred to as "d") having processing blades formed with three different patterns, 10e (hereinafter simply referred to as "e"), and 10f.
(Hereinafter simply referred to as “f”), def, dfe, e are determined according to the order of combination of the mold pieces 10.
fd, edf, fde (FIG. 5), fed, and the like can be used as the shape member 100 having different patterns.

A separately prepared mold piece (for example, 10 g
(Not shown) is replaced with any of abc
A new pattern such as bg can be formed, and further, one mold piece 10 can be removed or a pattern can be formed with four mold pieces 10 by adding a mold piece 10g (for example, abcg). . Thus, in the present invention, various patterns can be formed according to the order and number of the molds and the number of mold pieces used.

Also, as shown in FIGS.
6, for example, by fixing clockwise or counterclockwise from the mold piece in the state of FIG. 6 with respect to the rotation axis (about 30 ° in FIG. 6), a different pattern is formed. It becomes possible. Of course, these may be displaced by only one mold piece 10 or may be arranged by displacing a plurality of mold pieces 10, and the angle of the displacement can be arbitrarily selected. Thereby, it is possible to further configure a large number of patterns. In addition, although the method of shifting and installing at this time is not particularly limited,
As shown in FIG. 8, a plurality of holes 12 are formed in the plane portion of the mold piece 10 along the central axis, and the holes 12 are fixed by inserting a rod-shaped body 60 therein. Not only can it be fixed by shifting it by a certain angle just by selecting it, even after removing the mold piece 10 once,
The mold pieces 10 can always be easily installed at the same position, and the mold pieces 10 can be always installed at the same angle even if they are combined many times.

Further, as shown in FIGS.
The pattern can be changed simply by reversing and fixing the direction of j. Of course, not only 10j but also other types can be changed to further increase the types.

As described above, various patterns can be formed using the plurality of mold pieces 10. Further, the types can be further increased by variously combining the above methods. In this way, it is possible to form innumerable patterns that are incomparable compared to the case where a predetermined pattern is produced from one mold material from the beginning.

Further, even in the case of the same pattern, a pattern of various widths may be desired. In such a case, if the shape of the present invention is used, a plurality of shapes having the same shape are formed and combined. Accordingly, it is possible to form a mold material processed into various widths.

Next, a second embodiment of the present invention will be described with reference to FIG. Also in this embodiment, the point of forming one processing blade 11a by combining the mold pieces 10 is as follows.
This is similar to the first embodiment.

In the second embodiment, a cutting blade 11 is formed on each mold piece 10 along the edge. If such a mold member 100 is used, belt-shaped sheets of various thicknesses can be simultaneously manufactured. If a band-shaped sheet of another thickness is required, the thickness of the strip can be changed by changing one of the mold pieces 10 to another mold piece 10. As described above, according to the present invention, it is possible to appropriately produce a sheet having an arbitrary thickness by combining the strip 10 having the same thickness as the band-shaped sheet required at that time.

Further, as shown in FIG. 12, in order to form a pattern on the inner side, a mold piece 10 having a processing blade 11b having the same height as or slightly lower than the edge processing blade 11a is employed. It is also possible to produce a belt-like sheet on which is formed.

Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, two or more mold pieces 10
k, 10l are placed on the support member 40 with a gap therebetween. For the installation method at this time, for example, the support member 4
There is no particular limitation, such as mounting a position stopper (not shown) on the surface of the 0 shaft, or biting a small diameter material. By using the mold member 100 formed in this manner, it becomes possible to form a blank portion 25 in which no pattern is formed between the patterns on the sheet material 10 as shown in FIG.

In the case of a conventional mold material in which no machining blade is provided between patterns of the mold material, the mold becomes very large, the mold cost becomes extremely high, and the width of the blank area must be selected. Problems, such as not being able to
When the sheet material is repeatedly formed two or more times, it is difficult to process a blank portion to be processed with a certain width, and it is necessary to process the blank portion twice or more using a processing device. However, the present invention solves such a problem by combining mold pieces. If the pattern material 100 of the present invention is used, the blank portion 25 in which no pattern is formed between the patterns can be processed by selecting an arbitrary width by changing the gap between the pattern pieces 10. In addition, it is possible to perform processing while keeping the width constant.

Further, it is of course possible to form various patterns by combining the mold pieces provided with different patterns as described in the description of the first embodiment.

[0028]

According to the invention described in this claim, the means for exchanging the mold pieces by adopting means for forming a predetermined shape by combining a plurality of mold pieces having the same or different shapes is adopted. It is possible to produce various shapes of processing blades with various types of processing blades by changing, replacing or shifting, and it is possible to process many types of patterns on sheet materials simply by installing it on a conventional processing machine. As a result, the number of mold members can be reduced, and product cost can be reduced.

Further, as for the region to be processed, various widths and blank regions not to be processed can be easily and instantly formed by adjusting the number and arrangement of the mold pieces.
