Description

  The present invention relates to a patterning apparatus and a patterning method that are 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 ".

  DESCRIPTION OF EMBODIMENTS Hereinafter, a pattern firing apparatus and a pattern firing method according to a representative embodiment of the present invention will be described in detail with reference to the drawings. The drawings are for conceptual explanation 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 a sheet-like material such as leather is rubbed with reference to FIG. 1. When a sheet is put into the sheet-like material 1 shown in FIG. 1 (A), a cutting means such as a knife or beveler is cut. As shown in FIG. 1 (B-1), for example, a linear grooving groove 1a is formed using a leather tool having a blade (note that FIG. 1 (B-2) is the same as FIG. 1 (B-1). It is a side view of the sheet-like material 1 shown in FIG.

  And as shown in FIG.1 (C), the sheet-like material 1 can be easily bend | folded in the part of the grooved groove | channel 1a, and the linear pattern 1b can be formed in an outer surface. By making full use of the shape and structure, it is possible to produce products made of sheet-like materials (for example, leather products such as bags) with designs that have various patterns on the outer surface. It was difficult to cope with.

  Therefore, in a typical embodiment of the present invention, as shown in FIGS. 2 and 3, a laminate of a sheet-like material 1 and a mold 2 having a predetermined pattern 2a composed of convex portions and a base portion 2b. The body 4 is conveyed in the direction of the arrow X while being pressed against each other, and corresponds to the pattern 2a on the side opposite to the mold 2 in the sheet-like material 1 in the laminated body 4 in a state where the mold 2 is pressed and laminated. The portion P that is raised is rolled up by the cutting blade 6 provided on the downstream side in the conveying direction (FIG. 3 and FIG. 4B).

  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, first, as shown in FIGS. 2A and 2B, a sheet-like material 1 such as leather, a predetermined pattern 2a composed of convex portions, and a base portion 2b are provided. The stacked body 4 having the mold 2 is 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.

  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, it may be transparent from the viewpoint that the presence / absence of dust and the like, as well as 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 determined so that the rolled groove 1a is reliably 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, etc. A person skilled in the art can select as appropriate.

  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, the pattern 2 and a and the base 2b which comprise the type | mold 2 should just adhere | attach each other, for example with an adhesive agent. Further, in order to maintain the processing accuracy, it may be transparent from the viewpoint that the presence / absence of dust or the like and the state of deviation or deflection can be visually observed.

  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 substantially perpendicular to the paper surface of FIGS. 2 (A) and 2 (B). In the direction, it has a width substantially the same as the width of the sheet-like material 1.

  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 laminate 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. 2 (B) to the position shown in FIG. A part of the sheet-like material 1 in the laminated body 4 in the state of being cut is cut (cut) by the cutting blade 6.

  That is, as shown in FIG. 3, 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 arranged downstream in the direction of the arrow X. The cutting blade 6 provided on the side is rolled to form the groove 1a.

  Here, with reference to FIG. 4, 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 off by the cutting blade 6, The manner in which the groove 1a is formed will be described in detail.

  As shown in FIG. 4 (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 against each other by the upper roller 8a and the lower roller 8b, as shown in FIG. 4B, a portion P that protrudes downward corresponding to the convex portion of the pattern 2a is formed. Is done.

  The protruding portion P is cut and cut by the cutting blade 6, and as shown in FIG. 4C, a rolled groove 1 a is formed on the opposite side of the sheet material 1 from the mold 2. 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 in FIG.

  In the present embodiment, the above patterning method and patterning apparatus can efficiently form a groove in a sheet-like material using a mold having a desired pattern, and after subsequent bending processing, It is possible to mass-produce leather products having various designs by a simple process.

  Here, a more specific example is given. FIG. 5 is a plan view of a specific example of the mold 2 having a predetermined pattern 2a and a base 2b composed of convex portions. FIG. 6 is a plan view of the sheet-like material 1 in which the groove 1a is formed using the mold 2 of FIG. 5 and the above-described patterning method and patterning device of the present invention.

  By bending the sheet-like material 1 of FIG. 6 along the grooving groove 1a, as shown in FIG. 7, the final product (here, leather product) having a pattern 1b at a position on the surface side facing the grooving groove 1a. Bag).

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited only to these. For example, in the above-described embodiment, the case where the groove 1a is formed in the portion appearing in the pattern of the final product has been described. However, if the raised portion P is positioned at the end of the sheet-like material 1, so-called edge winding is performed. It can also be applied to. In other words, in the present invention, it is possible to simultaneously perform other whispering such as edge curling.

  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 can apply to various final products. For example, the present invention can also be applied to final products such as models, woodwork, furniture, and metal products.
