Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing an insole, and more specifically, when a shoe insole is die-cut from an insole laminated material formed by laminating a plurality of materials, a welder is used. The present invention relates to a method for manufacturing an insole using a mold that can be processed and cut at the same place.

(Prior Art) Conventionally, there have been proposed insoles which prevent damage to socks, have a good feeling in use, and have various uses for the purpose of keeping heat or cold.

For example, as a shoe insole that has heat retention, deodorization, or moisture absorption, each layer is made of a material with breathability in order from the top, a woven cloth with hairs planted on a woven fabric, and a mesh made of synthetic resin material such as vinylidene chloride resin Proposed insoles with any combination of screen, non-woven fabric with activated carbon, mesh screen made of synthetic resin material such as vinylidene chloride resin, honeycomb woven fabric made of synthetic resin material such as vinylidene chloride resin, aluminum vapor-deposited non-woven fabric, etc. Has been done.

By the way, as a method of manufacturing this kind of insole, as an insole laminated material obtained by laminating the materials constituting the various insoles, after pressing the peripheral edge portion to a desired shape and fusing, in a separate step. The cutting method was used to make the insole.

On the other hand, a method has also been proposed in which a blade is formed in a mold in which the insole laminated material is pressed, and the blade is melted and fused at the same time.

(Problems to be Solved by the Invention) In the conventional method for manufacturing an insole described above, for example, in the case of cutting after fusion of the former, the fusion bonding portion of the peripheral portion of the one-layer insole laminated material is used. It is necessary to use cutting dies that conform to each other in shape, a certain level of skill is required to conform the shape, and there are problems that many defective products are generated due to inconsistent shapes. I was doing it.

In addition, as a manufacturing process thereof, there is a problem in that the fusing process in the first step and the subsequent cutting process are complicated.

On the other hand, in the latter manufacturing method in which fusion welding is performed at the same time using a mold, although there are no problems in the above steps, not all are applicable as an insole laminated material, However, it has a problem that it is limited to fusing and fusing only the laminate based on the above materials.

Therefore, it is not always satisfactory as a means for manufacturing various insoles for the purpose of achieving a desired effect.

The present invention provides a method for manufacturing an insole which can be continuously manufactured with a simple structure in a method capable of manufacturing an insole by subjecting an insole laminated material to welder processing (fusing) and cutter processing. The purpose is to

(Means for Solving Problems) In order to achieve the above object, an insole laminated material formed by laminating a plurality of materials is provided with Welding is performed by pressing the protruding welder section, and then the outer periphery of the welder processing section is cut by the protruding cutter section at the tip of the insole type removing frame that follows the outer periphery of the insole type receiving frame. In the method of manufacturing an insole, insole type inner frame is integrally provided by interposing an elastic member inside the insole type outer frame, and the insole type inner frame is pressure-bonded to the insole laminated material. After that, the tip of the insole-type outer frame is made to project from the tip of the insole-type inner frame against the biasing force of the elastic member.

(Operation) As a material constituting the insole which can be applied to the above-described manufacturing method of the present invention, that is, a material as an insole laminated material, any material may be used as long as it constitutes a conventional insole. It is also applicable to, for example, woven cloth of wool, nylon, tricot, cotton, suf, etc., mesh screen or honeycomb woven cloth made of synthetic resin material such as vinylidene chloride resin, activated carbon impregnated non-woven cloth, copper impregnated non-woven cloth. , Aluminum vapor-deposited non-woven fabric, etc. can be laminated arbitrarily to form an insole laminate.

According to the method of the present invention, when the insole-type outer frame and the insole-type inner frame are integrated via the elastic member and pressed against the insole laminated material, the insole-type inner frame is first pressure-contacted. After that, since the insole type removing frame is pressed after that, the welder processing and the cutter processing can be performed in the continuous operation. Further, the molds of the insole mold removal frame and the insole mold inner frame can be made to have a simple structure, and one pressing device that presses against the insole laminated material can also be used.

The combinations that constitute such an insole laminate are listed below, but the invention is not intended to be limited thereto.

Wool / Nylon Tricot / Cotton Wool / Nylon Tricot / Suffer Wool / Vinylidene Chloride Resin Honeycomb Woven / Vinylidene Chloride Resin Mesh Screen / Vinylidene Chloride Resin Honeycomb Woven / Wool Tricot / Vinylidene Chloride Resin Honeycomb Woven / Vinylidene chloride resin mesh screen / vinylidene chloride resin honeycomb woven fabric / tricot etc.

In this case, in the case of a laminated material of different materials, the anchor effect is exerted on each material as a melt in the welding step, and cutting is performed along the outer periphery thereof, so that the laminated materials are not separated and various laminated structures are possible. It has the advantage of becoming one.

(Example) Hereinafter, the present invention will be described in more detail with reference to an example based on the drawings.

FIG. 1 is a top view of a mold for cutting and cutting used in the method for manufacturing an insole of the present invention, and FIG. 2 is an enlarged sectional view taken along the line AA in FIG.

That is, the mold 1 used in the manufacturing method of the present invention comprises an insole type removing frame 3 provided with a projecting cutter portion 2 at the edge tip of a foot-shaped frame, and a projecting structure fitted to the outer frame. It is composed of an insole type inner frame 5 which is located around the inside of the cutter part 2 and has a protruding welder part 4 at the tip, and which imitates a foot shape. The outer frame 3 and the inner frame 5 move up and down in FIG. It is free. The outer frame 3 is preferably made of iron and the inner frame 5 is preferably made of brass.

Therefore, a space 8 is provided between the bottom surface 6 of the inner frame 5 fitted to the outer frame 3 and the surface 7 of the outer frame so that the space 8 can be moved up and down. The elastic member 11, such as rubber, cardboard or a spring, is inserted. When the elastic member 11 is provided, the outer frame 3 and the inner frame 5 are provided so that the stroke length thereof is limited by the pin and the long groove.

Then, with the elastic member 11 interposed, the projecting cutter portion 2 provided on the outer frame 3 and the inner frame 5 existing around the inside thereof.
