Description

The present invention relates to a concavo-convex molded sheet in which protrusions are formed in close contact with an appropriate concavo-convex pattern, and can be applied to shoe soles such as jogging shoes, and in particular, on the upper surface of the protrusions, satin, sand, wood grain, geometric pattern The present invention relates to a method for producing a concavo-convex molded sheet to which a relief pattern such as the above is added and a plate for producing the concavo-convex molded sheet .

For example, projections (convex portions) are often formed on the soles of jogging shoes or the like for the purpose of preventing slipping on the road surface. In order to form such protrusions on the shoe sole, there is, for example, a method in which a sheet-like member having an appropriate concavo-convex pattern (concave-formed sheet) is attached to the shoe sole as an outer sole.
By the way, when manufacturing this kind of uneven | corrugated shaped sheet | seat, the method as shown, for example to Fig.8 (a) may be taken. That is, in this method, a stencil 33 ′ having appropriate holes is placed on a substantially flat base plate 32 ′ to form a protrusion-forming recess 31 ′, and then a liquid elastomer raw material is injected therein. A base cloth (base sheet 23) is installed thereon, and a desired uneven pattern is formed in close contact with the surface of the base cloth while curing the elastomer resin (see, for example, Patent Document 1).

And the convex part 25 'formed in this way is also formed in a stacked state in which several straight protrusions are stacked, as shown in FIG. 8B, for example, by stacking a plurality of stencils 33'. it can. Here, in the convex portion 25 ′ formed in a laminated state, the highest convex portion is designated as a high convex portion 25 T ′, and a lower convex portion is denoted as a low convex portion 25 S ′, and is distinguished for convenience.
Thus, in order to improve designability and differentiation as well as to prevent slipping, conventionally, the emphasis by the structure of the convex portion 25 'itself, that is, the laminated structure, has been mainstream, and the upper surface of the convex portion 25' remains smooth. There were many things. Of course, since the material of the convex portion 25 ′ is an elastomer resin, it is intended for matte surface (prevention of shine). For example, as shown in the enlarged view of FIG. There is a case where a fine irregular pattern (corresponding to a relief pattern 26 ′ described later) is formed on the upper surface of the convex portion 25 ′ by applying a texture process.

In this method, a fine concavo-convex pattern 26 ′ such as a textured surface or a grained surface is formed in an inverted state on the upper surface of the convex portion 25 ′ of the concavo-convex molded sheet 5 ′ by performing fine graining on the surface of the base plate 32 ′ in advance. That's it. At this time, since a metal material such as SUS (JIS symbol indicating stainless steel material) is generally applied to the base plate 32 ', conventionally, for example, etching (chemical corrosion) or liquid honing has been used in performing the above-described embossing. Etc. became a general processing technique.
However, as in the case of general mold production, the above-described processing method in which the material itself is engraved results in an excessive processing cost, which results in an increase in the cost of the concavo-convex molded sheet 5 ′. It was. That is, in order to obtain the concavo-convex molded sheet 5 ′ in which the fine concavo-convex 26 ′ is added to the convex portion 25 ′, if the conventional method such as etching is followed as it is, an expensive base plate 32 ′ must be produced. This was a big problem.

Further, because of such a processing technique such as etching, the fine concavo-convex pattern processed on the base plate 32 ′ is merely a simple pattern such as concavo-convex or satin, and there is no more. Therefore, it is theoretically difficult at a commercial level to finely process a highly regular pattern such as a geometric pattern or an intentional pattern in fine relief with fine irregularities, even though it is theoretically possible.
Further, in recent years, along with the diversification of products, the fine unevenness 26 ′ formed on the surface of the convex portion 25 ′ is strongly demanded not only for the anti-slip action but also for functions such as design properties. There is also a demand for product development in which only the pattern of the fine unevenness 26 'is different from the convex portion 25', and there are cases where many variations are required. However, producing expensive base plates 32 'one by one corresponding to such a product form was not very profitable, and there was a strong demand for a low-cost and efficient method.

The above-described problems can be solved by using the configuration of the invention described in each of the claims. That is, according to the first or fifth aspect of the invention, for example, a base plate can be produced simply by sticking a desired relief sheet on a substantially flat SUS plate. A base plate can be produced at low cost and efficiency. Especially when you want to change the relief pattern on the upper surface of the convex part, it is not necessary to create a new base plate, and you only need to replace (replace) the relief sheet on the base plate. This increases the degree of freedom in design. Of course, the relief sheet provided between the base plate and the stencil plate can be used repeatedly and is extremely economical.

  According to the second aspect of the present invention, the relief pattern formed on the upper surface of the convex portion of the concavo-convex molded sheet is a commercially available relief sheet with an embossed pattern (for example, a film sheet to be attached to a glass window for blindfolding) ) Is appropriately selected and used, so that the base plate can be produced at a lower cost and the cost of the concavo-convex molded sheet can be reduced. Moreover, since the variation of the concavo-convex molded sheet can be constructed by the relief pattern (pattern) of the relief sheet, such variation development can be realized at low cost, which is suitable for high-mix low-volume production.

Furthermore, according to the invention described in claim 3 or 6 , a plurality of stencil plates are stacked on the base plate to constitute a plate, so that the stencil openings can be formed in a straight shape, but the stacked convex portions can be easily formed. Can be formed. In addition, it is possible to change the elastomer to be injected into the protrusion-forming recess for each stencil, or it is possible to interpose another relief sheet between the stencil and the stencil, and various variations can be developed.

According to the invention described in claim 4 or 7 , when the concavo-convex molded sheet is viewed in plan, the relief pattern can be changed depending on the formation portion of the convex portion. For example, when a concavo-convex molded sheet is applied to a shoe sole, a relief pattern formed on the upper surface of the convex portion depending on the toe side (front side), heel side (rear side), arch (center portion), etc. And further variations can be developed at low cost.

The best mode of the present invention is as described in the following examples. In the description, a shoe 1 as shown in FIG. 1 is taken as an example, and an example in which a concavo-convex molded sheet 5 manufactured according to the present invention is applied to a shoe sole 3 of this shoe will be basically described. In addition, as an order of description, the configuration of the shoe 1 will be described first, and then the concavo-convex molded sheet 5 applied to such a shoe 1 will be described. Then, the plate | board 7 which forms the said uneven | corrugated shaped sheet | seat 5 is demonstrated, Then, the method of manufacturing the said uneven | corrugated shaped sheet | seat 5 using this plate | plate 7 is demonstrated.

First, prior to the description of the concavo-convex molded sheet 5 which is a main product to be manufactured in the present invention, a shoe 1 in which this is applied to the shoe sole 3 will be schematically described.
As shown in FIG. 1, for example, a shoe 1 such as a jogging shoe generally has an upper 2 on the upper side of the shoe that covers the foot, and a sole 3 on the lower side of the shoe that catches the road surface and transmits the leg strength to the ground. These are integrated as appropriate by bonding, sewing or the like.

Of these, the upper 2 includes an upper body 10, a tongue 11, an ankle pad 12, a heel guard 13, a toe guard 14, a stripe 15, a shoelace 16, and the like. On the other hand, the shoe sole 3 is composed of, for example, an inner sole (not shown), a midsole 17, an outer sole 18, and the like. The outer sole 18 has a non-slip projection called a tread 20 on a sole fabric 19 on the ground surface. Often formed on the side.
And in FIG. 1, the Example which used the uneven | corrugated molded sheet 5 manufactured from this invention as mentioned above for the shoe sole 3 (outer sole 18), ie, the convex part 25 of the uneven | corrugated molded sheet 5 manufactured from this invention. An example in which the tread 20 is formed by (described later) is shown.

  Next, the uneven | corrugated shaped sheet | seat 5 which is the main target product of this invention is demonstrated. As shown in FIGS. 1 and 2 as an example, the concavo-convex molded sheet 5 is formed by adhering an appropriate concavo-convex pattern 24 on a base sheet 23 as a base fabric, and the base sheet has such a basic structure. An appropriate convex portion 25 is formed on 23. Hereinafter, the base sheet 23 and the uneven pattern 24 will be further described.

  As the base sheet 23, various materials that can be conventionally used as a fabric (sole fabric 19) such as an outer sole, such as synthetic resin, rubber, and nonwoven fabric, can be applied. In addition, when applying a nonwoven fabric as the base sheet 23, either a thermoplastic fiber or a thermosetting fiber may be used. For example, Exseine (registered trademark) manufactured by Toray Industries, Inc., which is a backskin artificial leather, is used. Applicable. By the way, there are various colors such as yellow, orange, etc. in this EXSEINE (registered trademark). By contrasting the color tone of the base sheet 23 (sole fabric 19) and the convex part 25 (tread 20). The design effect by the color contrast can be expected.

  In addition, a normal nonwoven fabric sheet having a tear strength, a tensile strength, and an abrasion resistance, a thick film sheet, and the like can also be applied as the base sheet 23, and it has an adhesive property or a resin film coat. Things are also applicable. Moreover, as a normal nonwoven fabric sheet, what made the self-adhesion of 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 outer sole 18 having excellent buffering properties can be provided. In addition, when using a film sheet as the base sheet 23, it is difficult to express the contrast of the material in terms of design as compared with artificial leather or non-woven fabric, but the design can be enhanced by the color contrast.

  On the other hand, the concavo-convex pattern 24 is formed of an elastomer, and a polyurethane elastomer is applied as an example in this embodiment. Here, the elastomer is a general term for high-molecular substances having high elasticity such as rubber at room temperature, and is a so-called rubber-like elastic body. In addition, an elastomer having a single property is basically applied. For example, when it is desired to vary the height of the convex portion 25 depending on the forming position, or when several convex bodies are intentionally stacked step by step. When it is desired to form the portion 25, the convex portion 25 can be constituted by a plurality of elastomer raw materials having different properties. Incidentally, the properties here are elastomers having different colors, hardness, elasticity, wear resistance, repulsive force, vibration absorption, thickness, specific gravity and the like.

  The polyurethane elastomer is a mixture of a prepolymer and a polyisocyanate, which is cured by heating. Particularly, as a suitable polyurethane elastomer to be supplied by spraying from a nozzle, Nippon Synthetic Chemical Industry Co., Ltd. There are solvent-free quick-curing urethane resins, such as the brand name Efletane. It is desirable to heat the elastomer liquid raw material before spray mixing with a nozzle, and it cures with a gel time of about 20 seconds. In addition, it is possible to add a separate solvent to adjust the viscosity and hardness. Furthermore, as polyurethane elastomers, the prepolymer Nippon Polyurethane Co., Ltd. (Nipporan) (registered trademark) and the polyisocyanate Dainippon Ink Co., Ltd. (Pandex (registered trademark)) are mixed. SX-320A & B manufactured by KK, MU-670A & B manufactured by Nippon Pernox Co., Ltd., or the like can be used.

In addition, when it is necessary to prevent the raw material outflow from the protrusion formation recessed part 31 mentioned later, it is preferable to mix a thickener with these raw materials suitably.
Furthermore, it is also possible to apply a photocurable resin that cures in a short time by irradiation with ultraviolet rays as another elastomer. Furthermore, a phosphorescent pigment or the like can be added to such an elastomer, and in this way, other functions such as improvement of night visibility (safety) can be added.
And as mentioned above, what applied such an uneven | corrugated shaped sheet | seat 5 to the shoe sole 3 (outer sole 18) is the Example of FIG. 1, More specifically, the sole fabric 19 is equivalent to the base sheet 23. The convex portion 25 corresponds to the tread 20. Of course, the convex part 25 here has an anti-slip action as a main function, but also has a function of improving the design of the shoe sole 3.

And the uneven | corrugated shaped sheet | seat 5 manufactured from this invention is, as shown in FIG. 1, 2, for example, on the uppermost surface of the convex part 25 (the contact surface of the tread 20 in the case of the shoe sole 3), satin, A relatively fine relief pattern 26 such as a wood grain or a geometric pattern is added. Of course, the relief pattern 26 does not need to be added to all the convex portions 25 on the base sheet 23. For example, when the uneven molding sheet 5 is applied to the shoe sole 3, the toe side (front side) or the heel side (rear side). Side) or an arch portion (intermediate portion) or the like. Incidentally, in the present embodiment, the protrusions (projections 25) to which the relief ground pattern 26 is not added are formed somewhat lower than the protrusions to which the relief ground pattern 26 is added. Is a low convex portion 25S, and a protrusion provided with a relief pattern 26 is a high convex portion 25T. In this embodiment, the low convex portion 25S is also formed around the high convex portion 25T.

  Further, in the present embodiment, the example in which the concavo-convex molded sheet 5 is applied to the shoe sole 3 is shown. However, it is also possible to apply to the upper 2, and in this case, the base sheet 23 corresponds to the upper main body 10. The convex portion 25 of the concave / convex pattern 24 corresponds to the stripe 15 or the like. Of course, the concavo-convex molded sheet 5 is not limited to such an application to the shoe 1, but considering that the convex portion 25 itself mainly has a non-slip function, a glove having a non-slip projection formed thereon. It can be applied to various members such as grips for various rackets or gloves for ball games.

Next, a plate 7 for producing such a concavo-convex molded sheet 5 will be described. The plate 7 reproduces the concavo-convex pattern 24 (convex portion 25). As shown in FIG. 3, as an example, a substantially flat base plate 32, a relief sheet R having appropriate concavo-convex on the surface, and an appropriate The stencil 33 is formed with an opening 33a having the shape of, and a desired projection-forming recess 31 is formed by overlapping these.
In this embodiment, a description will be given by taking as an example a plate 7 (projection forming recess 31) formed by combining a base plate 32 and a stencil plate 33 one by one. Further, in the following description, after the relief sheet R is pasted on the base plate 32 in advance, the stencil 33 is stacked thereon to form the plate 7, and at that time, the base plate 32 and the stencil 33 are separated by a magnetic force. It is adsorbed by. Of course, the relief sheet R does not necessarily have to be stuck on the base plate 32, and can be fixed by simply sandwiching the base plate 32 and the stencil plate 33 by magnetic force adsorption.

Hereinafter, the individual production of the stencil 33 and the base plate 32 and the manner in which the plate 7 is produced by superposing these will be described.
(1) Manufacture of Stencil In the manufacture of the stencil 33, an opening 33a corresponding to the shape and height of the concavo-convex pattern 24, that is, the convex portion 25 is formed in a substantially flat starting material. As the stencil 33, for example, a metal material such as SUS is applied, and in order to form the opening 33a therein, for example, it is processed by various conventionally known methods such as mechanical cutting and punching. It is possible.

(2) Production of base plate (sticking of relief sheet)
In producing the base plate 32, a relief plate R having a desired relief pattern is attached to a base plate main body 32M such as SUS having a substantially flat plate shape, and the base plate 32 corresponding to the uppermost surface of the convex portion 25 corresponds to the base plate 32. A fine uneven pattern is formed on the part. The formation of the concavo-convex pattern, that is, the attachment of the relief sheet R, corresponds to the conventional texture processing, and the production process of the base plate 32 is completed by the attachment of the relief sheet R.

Hereinafter, the relief sheet R will be described. As the relief sheet R, various sheet-like members can be applied as long as the surface has irregularities. However, in consideration of availability, cost, etc., existing sheet-like members such as glass windows are available. It is preferable to apply a so-called blindfold sheet or film. Of course, since the relief sheet R bears one component of the plate 7, the following points are considered.
First, the relief sheet R is required to have heat resistance. This is determined by the elastomer resin to be selected. When the polyurethane elastomer of the above embodiment is used, the sheet molding temperature (projection molding temperature) is about 60 ° C. Cost.
In addition, the material (resin material) of the relief sheet R is also considered. For example, when the polyurethane elastomer of the above embodiment is used, a release agent is not necessary, so that PP (polypropylene), PE ( A resin material such as polyethylene and PET (polyethylene terephthalate) is preferable. Of course, materials such as PVC (polyvinyl chloride) and PU (polyurethane) can be applied if the release agent is accepted.

Further, the relief sheet R is preferably about 200 μm thick. This is because, if the relief sheet R is too thick, it is considered that the resin curing is adversely affected due to a decrease in heat conductivity, and the base plate 32 and the stencil 33 are closely fixed by magnetic force. This is because it is considered to have an adverse effect on the environment. On the contrary, when the relief sheet R is too thin, wrinkles are more easily broken and the relief sheet R is preferably about 200 μm thick.
Moreover, it is preferable that the relief sheet | seat R has the uneven | corrugated space | interval of a surface narrow, and the uneven | corrugated depth (depth of a relief pattern) of a surface is about 50 micrometers or less. This is because if the unevenness is deeper than this, the elastomer enters between the relief sheet R and the stencil 33 and tends to appear as burrs around the convex portion 25. As described above, the relief pattern preliminarily formed on the relief sheet R is mainly a flat uneven pattern with relatively shallow carving, such as satin, sand, wood, and geometric pattern.

Note that when the relief sheet R is stuck on the base plate 32, it may be pasted at least at a location corresponding to the convex portion 25 (projection forming concave portion 31) where the relief pattern 26 is formed, and the surface of the base plate main body 32M is not necessarily required. It is not necessary to stick the whole. Of course, as described above, when the relief sheet R is simply fixed by adsorbing the magnetic force between the base plate 32 and the stencil 33 without adhering the relief sheet R, the base plate 32 is manufactured by using the relief sheet R as a base. It is only placed in close contact with the plate body 32M.
Incidentally, the conventional method for producing the base plate 32 is to mask the starting material (base plate main body 32M) having a substantially flat plate shape, and then perform etching or the like to form irregularities such as wrinkles. The cost of the base version 32 was excessive. However, in the present invention, since the relief pattern originally formed on the relief sheet R is the unevenness of the base plate 32, the production cost of the base plate 32 can be suppressed extremely low.

(3) Superimposition of base plate and stencil After the base plate 32 and the stencil 33 are individually manufactured, the plate 7 is manufactured by superimposing them. At this time, of course, the stencil 33 is superposed so that the relief sheet R stuck on the base plate 32 is sandwiched between the stencils 33. Further, when the base plate 32 and the stencil 33 are overlapped, they are attracted by magnetic force.
Here, the convex portion 25 has an outer shape formed by the opening 33a of the stencil 33, and the relief pattern 26 formed on the upper surface thereof is transferred and formed by the relief sheet R. If you want to change the pattern, or if you want to update the relief sheet R with the relief of the relief pattern worn (worn) over a long period of use (manufacturing), just replace the relief sheet R, Patterns can be changed and updated at a much lower cost than creating a new base plate 32. That is, the production cost of the base plate 32 when changing the pattern or the like is extremely low, and is particularly suitable for multi-product and small-quantity production, and the design can be remarkably improved.

Next, a method for manufacturing the concavo-convex molded sheet 5 using the plate 7 described above will be described.
(1) Injection of Elastomer To manufacture the concavo-convex molded sheet 5, as shown in FIG. 4A, a liquid elastomer is injected into the protrusion-forming recess 31 formed by the base plate 32 and the stencil 33. . In addition, when applying polyurethane elastomer as an elastomer raw material, using a static mixer or the like that is widely used in the industry, mixing two liquids in a cylinder and injecting them from the nozzle, A method of spraying while mixing can be employed.

(2) Squeegee For example, as shown in FIG. 4B, the squeegee squeegee removes the elastomer protruding from the projection forming recess 31 by injecting the elastomer resin almost uniformly into the projection forming recess 31 and then wiping the injection surface with the squeegee tool S. It is a work to remove. As a result, the resin injected into the projection forming recess 31 is adjusted to substantially the same height as the upper surface of the plate 7, and the elastomer remaining on the plate 7 without entering the projection forming recess 31 is removed.

(3) Installation of the base sheet to de-plate After the squeegee, the base sheet 23 is set on the upper surface of the plate 7 and pressed against the plate 7 with an appropriate pressure. Then, the elastomer is cured until the plate can be removed in this state. Thereafter, when the base sheet 23 is separated from the plate 7, the concave / convex pattern 24 having the relief pattern 26 on the upper surface of the convex portion 25 is separated from the plate 7 in a state of being integrated (attached) to the base sheet 23, When this is completely cured, the target concavo-convex molded sheet 5 is obtained (see FIG. 4C). Of course, the relief pattern 26 does not necessarily have to be formed on all the convex portions 25, and may be formed on at least some of the convex portions 25.
[Other Examples]

  The present invention has the above-described embodiment as one basic technical idea, but the following modifications can be considered. That is, in the basic embodiment described above, only one stencil 33 is set on the base plate 32, and the stencil 33 has an opening 33a formed in a straight shape. However, the opening 33a of the stencil 33 does not necessarily have to be formed in a straight shape. For example, as shown in FIG. 5, it is possible to form the laminated convex portion 25 with only one stencil 33. is there. In addition, in this figure, the low protrusion body in which the relief ground pattern 26 is not formed becomes the low convex part 25S mentioned above.

  As another method for forming the convex portions 25 in a laminated state, for example, as shown in FIG. 6, a plate 7 (protrusion) in which the same number of stencils 33 as the number of layers (maximum number of layers) is stacked on the base plate 32 It can also be formed using the formation recess 31). In this case, all the openings 33a formed in each stencil 33 can be formed in a straight shape, and the stencil 33 can be easily manufactured. In addition, when it is necessary to distinguish the stencil 33 which piled up several sheets, respectively, it distinguishes from the thing close to the base plate 32 as 33A, 33B .... Reference numeral P in the figure denotes a positioning member such as a pin for easily determining the overlapping position of the plurality of stencils 33.

  When the plate 7 is formed by stacking a plurality of the stencils 33 as shown in FIG. 6, the stencil 33A that receives the stencil 33B has a portion of the upper surface of the low convex portion 25S or In order to form all of them, the function of the base plate 32 is substantially taken. For this reason, such a stencil 33 can also be a kind of the base plate 32 in a broad sense. Therefore, the “base plate” described in claim 1 includes such a stencil 33. That is, for example, when the convex portion 25 is formed in a stacked state, the relief ground pattern 26 is formed on the upper surface of the low convex portion 25S even if the relief ground pattern 26 is not added to the upper surface of the high convex portion 25T. What is included is also included in the present invention.

  Furthermore, when a plurality of stencil plates 33 are used, a relief sheet R can be provided between each stencil plate 33 as shown in FIG. Incidentally, in FIG. 6, the relief sheet R provided between the base plate 32 and the stencil 33A and the relief sheet R provided between the stencil 33A and the stencil 33B are used in a different pattern, and the top of the high convex portion 25T is used. The relief pattern 26 formed on the upper surface is different from the relief pattern 26 formed on the upper surface of the low convex portion 25S.

  Further, when the convex portions 25 are formed in a laminated state by using a plurality of stencils 33, it is possible to make the elastomer material different for each stencil 33. Of course, in this case, all the stencils 33 from the beginning. Rather than superimposing, the elastomer is injected into each stencil 33 step by step, and this is semi-cured, and then a new stencil 33 is stacked, and injection of different or identical elastomers and repeated semi-curing are repeated. The convex portion 25 in the stacked state is formed.

Further, in the basic embodiment described above, the relief pattern 26 added to one concavo-convex molded sheet 5 (convex portion 25) is basically the same pattern. For example, as shown in FIG. Moreover, it is possible to appropriately change the pattern of the relief pattern 26 to be added to the upper surface of the convex portion 25 in each part of the single concavo-convex molded sheet 5. In FIG. 7, when the uneven molding sheet 5 is applied to the shoe sole 3 as an example, the relief sheet R to be applied is changed at each of the toe side, the heel side, and the arch, and the relief pattern 26 formed here is changed. It shows how to change.
As described above, the relief pattern 26 can be appropriately changed not only by the height of the convex portion 25 but also by a planar formation portion of the convex portion 25, and further variation development can be realized at low cost. It is.
