[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uneven shaped sheet manufacturing apparatus used for efficiently mass-producing an uneven shaped sheet formed by closely forming an uneven pattern on a surface of a base cloth such as an outer sole of a shoe sole. It is about.

[0002]

BACKGROUND OF THE INVENTION In order to reduce the weight and improve the impact absorption of sports shoes used for various sports such as jogging, basketball and tennis, an outer sole, which is the lowest layer of the sole directly in contact with the ground, is used. Is made of solid rubber or high-density sponge, and the upper layer is constructed by stacking one or more sponges such as EVA (ethylene vinyl acetate) that are lightweight and have excellent cushioning properties, and try to make the shoe sole a multi-layer structure. Has been done.

However, although these solid rubbers and high-density sponges are relatively hard and exhibit excellent effects in terms of ground gripping force and wear resistance, on the other hand, they are heavy and difficult to reduce in weight. was there.

Therefore, in recent years, in addition to the improvement of the material for the sole, various molding methods for the sole have been devised. For example, a method in which a polyurethane resin film on a non-woven fabric sheet and a liquid polyurethane composition before forming non-slip projections are placed in a mold and heat-cured to integrally bond them (Japanese Patent Laid-Open No. 1-3106).
No. 01) is mentioned as an example. Further, even the applicant of the present invention, the stencil is placed in close contact with the non-woven fabric, the polyurethane elastomer containing a thickener is poured into the stencil,
A method of forming an embossed sheet by squeegeeing and then heat-curing to form an embossed sheet "Patent application 4"
No. 185922) and many other applications.

However, when actually manufacturing an uneven molded sheet using such a manufacturing method, it is also taken into consideration how efficiently and uniformly a uneven molded sheet can be manufactured. There must be. That is, when such a manufacturing method is used, it is not possible to immediately produce a large quantity of unevenly formed sheets of the same quality, but an apparatus for producing unevenly formed sheets that can realize this is needed.

[0006] Such a manufacturing apparatus inherently has the following problems to be overcome, and only when these problems are solved, the above-mentioned effect that the concavo-convex molded sheet of the same quality can be mass-produced can be achieved. Of. First, in order to mass-produce the uneven shaped sheet, a continuous operation type or tact operation type transport line type uneven shaped sheet manufacturing apparatus is assumed. However, while conveying the laminate including the base cloth and the stencil until the formation of the uneven pattern is completed,
It is not easy to maintain the adhesion of these laminates, and there is an inherent problem to be overcome in terms of what kind of adhesion means should be adopted and shared with the transportation means.

Further, foreign matters such as residual lumps of the raw material adhered to the stencil etc. used once, and in order to reuse such stencil etc., the stencil etc. should be washed to remove such foreign matters. , Must be dried and then re-supplied. However, if such work is performed outside the transport line, a considerable number of stencil plates and the like are required, resulting in a reduction in the manufacturing efficiency of the manufacturing apparatus for the unevenly shaped sheet.

Further, after the squeegee treatment, a lot of raw materials having high viscosity and difficult to remove adhere to the squeegee tool. Therefore, it is very difficult to remove this immediately after the squeegee treatment. Furthermore, there is an inherent problem to be solved in terms of how to efficiently heat the laminate composed of a base cloth, a stencil, etc. in a small space to cure the raw material existing in the pores of the stencil. Was.

This is an attempt to devise the arrangement of equipment and to develop the mechanism of various equipment.

The configurations of various devices will be described in detail, and thereafter, the flow of manufacturing the concavo-convex shaped sheet using the manufacturing device of the present invention will be described, and at the same time, the operating state of the manufacturing device of the present invention will be referred to.

[I] Configuration of Concavo-convex molded sheet S Concavo-convex molded sheet S manufactured by the manufacturing apparatus of the present invention
Is formed by closely forming an uneven pattern 16 of a predetermined shape on the base cloth 15. Specifically, various footwear soles such as athletic shoes 17, design provided on the upper part of athletic shoes 17, leather shoes, sandals, etc., stripes (line) for reinforcement protection, for stimulating vase of healthy sandals Protrusion surface, bicycle and tennis, racket grip for badminton, bicycle saddle and snowboard, surfboard non-slip,
Baseball, soccer, bicycles and other various competition gloves, grips for various tools, grips for cameras and video cameras, etc.

Is bonded to the base cloth 15 in close contact.

As the base cloth 15, for example, various materials such as synthetic resin, rubber and non-woven cloth which have been conventionally used as a base cloth for the outer sole of the athletic shoe 17 can be applied. When a non-woven fabric is used as the base fabric 15, either a thermoplastic fiber or a thermosetting fiber may be used, and an example thereof is EXCENE (registered trademark) manufactured by Toray Industries, Inc., which is a backskin artificial leather. can do. By the way, this Exeine (registered trademark) contains yellow,
Since there are various colors such as orange, by designing the concave-convex pattern 16 to be described later in, for example, a black color, the shoe sole 18 can be designed with a color contrast.

In addition to the usual non-woven fabric sheet having tear strength, tensile strength, and abrasion resistance, a thick film sheet or the like can be applied, and one having adhesiveness or one having a resin film coat may be used. . As a normal non-woven sheet, one obtained by self-bonding elastic long fibers such as urethane is suitable. In this case, for example, if a thick non-woven sheet having a thickness of about 1 cm is applied, the shoe sole 1 having excellent cushioning properties can be obtained.

It is preferable to incorporate a thickener.

A specific example of the thickener is AEROSIL (registered trademark) manufactured and sold by Nippon Aerosil Co., Ltd. This is the highest purity silica (S
iO ₂ 99.8%), is composed of ultrafine particles of 7 mμ to 50 mμ, and is a harmless substance having high surface area and high dispersibility. This AEROSIL (registered trademark) serves as a thickener because it can impart the rheological properties necessary for processing liquid substances such as polyester and epoxy resin with a small amount of addition due to the action of hydrogen cross-linking of silanol groups on the surface. It has the function of. In addition to the above AEROSIL, it is of course possible to add other fillers. Further, as the elastomer liquid raw material P, it is also possible to apply a photocurable resin such as an ultraviolet curable resin which is cured in a short time by irradiation with ultraviolet rays.

And such an elastomer liquid raw material P

And a removing means 84 for removing foreign matter attached to the surface of the. For example, the removing means 84 has, as an example, a brushing roller 85 in which three rollers are arranged vertically, three rollers in total, and the brushing rollers 85 are all driven to rotate. It should be noted that the spacing between the brushing rollers 85 arranged above and below, the rotation direction,
It is desirable that the rotation speed and the like can be appropriately changed according to the thickness of the base plate B or the stencil H to be conveyed.
