Description

  The present invention relates to a patterning apparatus suitable for a sheeting material such as leather.

  Conventionally, various leather products have been manufactured and sold, and various techniques are used as a method of forming a pattern on the surface in order to realize various characteristic designs. One of the techniques is so-called “wrinkling”, in which a pattern is formed by folding the leather at the crushed part.

  Here, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-123200) states that “a pattern is formed by embossing a pattern on a silver surface of leather and compressing a concave portion and a convex portion not compressed. The first step of forming on the surface: the second step representing the nubuck by scraping the embossed leather convex portion within a depth range that does not cause the concave portion to disappear, and eliminating the silver surface of the convex portion. A method is disclosed that includes a third step in which moisture is contained in the processed skin, thereby releasing the compressed state of the recessed portion that has been pressed and compressed to restore the thickness thereof (Patent Document 1). , Claims).

  In addition, for example, Patent Document 2 (Utility Model Registration No. 3195757) states that “the back side of the leather is spread almost linearly at a plurality of locations, and the thickness of the added portion is 1.2 mm or less. The characteristic leather material. ”Or“ The reverse side of the leather is spread almost linearly at a plurality of locations, and the thickness of the added portion is less than ½ of the thickness of the other portions. ” Leather material ".

  However, the technique of Patent Document 1 is based on the premise that leather having the surface of the nipple layer (silver surface) and the raised surface of the back side (nubuck) is used, and is inferior in versatility, and is formed by embossing. The surface of the convex portion must be scraped, and the concave portion compressed by embossing must be returned to its original state by containing moisture.

  Moreover, the technique of the said patent document 2 raises a pattern on the surface by rolling the back surface of leather, and there exists a limit in the expression mode of a pattern. Moreover, since this technique is based on the premise that the punching is performed manually without using a mold, there is a problem that it is unsuitable for mass production and cannot be handled at all.

  Hereinafter, representative embodiments of the present invention will be described in detail with reference to the drawings. Note that the drawings are for conceptual description of the present invention, and for ease of understanding, the dimensions, ratios, or numbers may be exaggerated or simplified as necessary. Is not limited to these.

  First, a description will be given of a state in which sheeting material such as leather is applied with reference to FIG. 1. Sheeting material 1 includes a plurality of layers 11 to 14 as shown in FIG. It is produced by adhering adjacent layers as shown in B). Here, the number of layers constituting the sheet-like material may be two or more. The material of each layer may be natural leather or artificial leather, as long as it can be spread like resin or wood. A thin metal layer may be used. Further, the material, thickness, hardness, density, color, and the like of each layer may be different from each other.

  When putting a sheet into such a sheet-like material 1, as shown in FIG. 1 (C), using a leather tool having a cutting blade such as a knife or a bevel as cutting means, for example, a linear cutting groove 1a Form. At this time, the groove 1a is formed over a plurality of layers and the inner layer is exposed to the outside, so that the pattern 1b appears on the outer surface. Here, unlike the case where the crease is formed, the groove 1a does not need to be connected to each other as shown in FIG. 9, for example, and may be interrupted.

  By making full use of the shape and structure of the groove 1a, for example, as shown in FIG. 9, a product made of sheet-like material having various patterns 1b on the outer surface (for example, leather products such as bags) can be obtained. Can be made.

  Therefore, in order to produce such a sheet-like material, in a typical embodiment of the present invention, as shown in FIG. 2 and FIG. 3, a sheet-like material 1 and a predetermined portion constituted by a convex portion are used. The laminated body 4 of the pattern 2a and the mold 2 having the base 2b is conveyed in the direction of the arrow X while pressing each other, and further, the mold 2 is pressed and laminated as shown in FIGS. Thus, a portion P of the sheet material 1 in the laminate 4 that protrudes in correspondence with the pattern 2a on the side opposite to the mold 2 is spread with a cutting blade 6 provided on the downstream side in the transport direction.

  In the present embodiment, the upper roller 8a, which is a conveying means for conveying the laminate 4 of the sheet-like material 1 and the mold 2 having the predetermined pattern 2a and the base portion 2b formed by the convex portions while pressing each other. And the pattern rolling device 10 including the lower roller 8b and the cutting blade 6 provided on the downstream side of the conveying means.

  More specifically, in this embodiment, as shown in FIGS. 2 and 3, first, a mold having a sheet-like material 1 composed of a plurality of layers, a predetermined pattern 2a composed of convex portions, and a base portion 2b. 2 and 4 are conveyed in the direction of the arrow X so as to be sandwiched between the upper roller 8a and the lower roller 8b rotating in the directions of the arrow Ya and the arrow Yb, respectively. At this time, the sheet-like material 1 and the mold 2 in the laminate 4 are pressed against each other. Moreover, it is preferable that the sheet-like material 1 is arranged so that the surface to be the front side faces the lower roller 8b side (the side opposite to the mold 2).

  Here, the mold | type 2 can be produced using various materials in the range which does not impair the effect of this invention. For example, when the predetermined pattern 2a composed of convex portions is sandwiched between conveying means such as the upper roller 8a and the lower roller 8b, the convex portions change in shape and the groove 1a cannot be formed. For example, the resin may be made of various resins, leather, recycled leather, wood, metal, or the like.

  In addition, the pattern 2a preferably has a certain degree of flexibility from the viewpoint of being easily transported by being sandwiched between the upper roller 8a and the lower roller 8b and reliably serving as a mold. . In order to maintain the processing accuracy, the pattern 2a may be transparent from the viewpoint that the presence / absence of dust and the like and the state of displacement and deflection can be visually observed.

  What is necessary is just to design suitably the convex-shaped part which comprises the pattern 2a according to the design of the desired groove 1a, and the pattern to express on the surface of a final product. For example, the height of the convex portion is such that the groove 1a having a desired depth is formed according to conditions such as the material of the sheet-like material 1, the hardness, the distance between the upper roller 8a and the lower roller 8b, and the like. Thus, those skilled in the art can select as appropriate. In particular, it is preferable to set the height of the convex portion so that the inner layer of the sheet-like material 1 is exposed from the rolled groove 1a. Moreover, the convex part may be arrange | positioned so that it may align in the width direction like FIG.7 and FIG.8, for example, and may be interrupted (it does not need to be connected). The convex portions are also preferably arranged so as to be substantially orthogonal to a preset conveyance direction of the sheet-like material 1 (for example, directions indicated by arrows S and T in FIGS. 7 and 8). By arranging the convex portions in this way, the design of the pattern 2a can be reproduced more faithfully on the sheet-like material 1 when the pattern is rolled with the pattern rolling device 10.

  In addition, various materials can be used for the base 2b without particular limitation as long as the pattern 2a can be held and fixed. For example, various papers and resin sheets can be used. In addition, what is necessary is just to adhere | attach the pattern 2a and the base 2b which comprise the type | mold 2 with an adhesive agent, for example. Further, in order to maintain the processing accuracy, the base 2b may be transparent from the viewpoint that the presence or absence of dust or the like and the state of deviation or twist can be visually observed.

  In the present embodiment, one mold 2 may be used, or a set of molds 2 and 2 ′ having different patterns 2 a may be used as shown in FIGS. 7 and 8, for example. By using a set of molds 2 and 2 ′, it is possible to display various patterns 1 b on the sheet-like material 1 while maintaining productivity.

  A cutting blade 6 is disposed on the downstream side of the upper roller 8a and the lower roller 8b in the direction of the arrow X, and the cutting blade 6 is in a direction substantially perpendicular to the paper surface of FIG. Has substantially the same width.

  Moreover, the cutting blade 6 has a so-called single-edged structure, and the inclined surface of the single-edged blade is directed downward (may be directed upward). The cutting blade 6 may be a double blade and may have various shapes. In addition, although this embodiment is an aspect which uses this cutting blade 6 as a cutting | disconnection means, various cutting | disconnection means currently used in the field of leather processing, such as cracking machines, such as a band machine and a slicer, can also be used, for example. .

  Thus, the laminated body 4 conveyed in the direction of the arrow X by the upper roller 8a and the lower roller 8b is pressed and laminated in the process of being conveyed from the position shown in FIG. 3 to the position shown in FIG. Part of the sheet-like material 1 in the laminate 4 is cut (cut) by the cutting blade 6.

  That is, as shown in FIGS. 4 and 5, in the sheet-like material 1 of the laminate 4, a portion P that protrudes corresponding to the convex portion of the pattern 2 a on the side opposite to the mold 2 is indicated by an arrow X. A cutting groove 6 provided on the downstream side in the direction is rolled to form a groove 1a. At this time, the position of the cutting blade 6 can be set so that the inner layer of the sheet-like material 1 is exposed from the rolled groove 1a, that is, a part of the sheet-like material 1 is cut out over a plurality of layers. preferable.

  Here, with reference to FIG. 6, in the sheet-like material 1 of the laminate 4, a portion P that protrudes corresponding to the convex portion of the pattern 2 a on the side opposite to the mold 2 is cut by the cutting blade 6, The manner in which the groove 1a is formed will be described in detail.

  As shown in FIG. 6 (A), the laminated body 4 includes a sheet-like material 1 and a mold 2 having a predetermined pattern 2a and a base portion 2b composed of convex portions. When the laminate 4 is conveyed while being pressed by the upper roller 8a and the lower roller 8b, as shown in FIG. 6B, a portion P that protrudes downward corresponding to the convex portion of the pattern 2a is formed. Is done.

  This protruding portion P is cut and cut across a plurality of layers by the cutting blade 6, and as shown in FIG. 6C, a groove 1a is formed on the opposite side to the mold 2 of the sheet-like material 1. Is formed. The cutting blade 6 may be adjusted, for example, so that the tip of the cutting blade 6 is disposed along the position indicated by the broken line Q in FIG.

  In the present embodiment, the patterning method and the patterning apparatus 10 as described above can efficiently form the groove 1a in the sheet-like material 1 using the mold 2 having the desired pattern 2a, and the subsequent bending. Through processing and the like, it is possible to produce a large number of sheet materials having various designs in a simple process. At this time, the pattern 1b generated for the same pattern 2a is slightly different according to various conditions of each process such as the structure such as the thickness of the sheet-like material 1, the conveyance speed, the weather at the time of processing, From the sheet-like material 1, a sheet material having a unique design composed of a three-dimensional pattern having a three-dimensional surface is obtained, and a possibility that a better design is born is also expected.

  Here, a more specific example is given. 7 and 8 are plan views of a specific example of the molds 2 and 2 'having a predetermined pattern 2a and a base 2b formed of convex portions. The molds 2 and 2 'are designed to be used as a set. Therefore, the sheet-like material 1 is spread twice in the order of the molds 2 and 2' or the molds 2 'and 2. In addition, if the design of the other mold is displayed on each mold by, for example, a line, the orientation of the molds 2 and 2 ′ when the stacked body 4 is prepared can be set correctly.

  In addition, the direction at the time of conveyance is preset for each mold. For example, the direction at the time of conveyance of the mold 2 is the direction of the arrow S, and the direction at the time of conveyance of the mold 2 ′ is the direction of the arrow T. The direction at the time of conveyance is set from the viewpoint of reproducing each type of design more faithfully. For example, it is preferable to set the direction to the direction in which the convex portion constituting the pattern 2a extends. As for the direction during transportation, the pattern and design to be formed can be variously changed depending on the combination of the direction and the composition of the sheet-like material 1 and the molds 2 and 2 ′, etc. Depending on the situation, it may be determined appropriately.

  As a result, a pattern 1 b as shown in FIG. 9 is formed on the sheet-like material 1. FIG. 9 is a plan view of the sheet-like material 1 in which the cutting groove 1a is formed by using the molds 2 and 2 'of FIGS. 7 and 8 and the above patterning method and patterning apparatus 10 of the present invention.

  A final product (for example, a bag) having a pattern 1b corresponding to the groove 1a can be obtained by appropriately bending the sheet-like material 1 of FIG.

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited only to these, A various design change is possible and all the aspects of this design change are also the technical scope of this invention. include. For example, the patterning device 10 may include a device that automatically replaces the molds 2 and 2 ′, or may include a plurality of combinations of the upper roller 8 a and the lower roller 8 b. The long sheet-like material 1 may be cut into the long sheet-like material 1 using the molds 2 and 2 ′ and subsequently subjected to the patterning process of the present invention. .

  Moreover, in the said embodiment, although the case where a final product was a bag was demonstrated, depending on the kind of sheet-like material 1, it is applicable to various final. For example, products such as belts, shoes, wallets, pouches, book covers, and the like can be mentioned. Furthermore, the present invention can be applied to products such as models, woodwork, furniture, and metal products, for example, on the surface of the final product.
