Description

本発明は、皮革等のシート状材料への漉き加工に好適なパターン漉き装置及びパターン漉き方法に関する。 The present invention relates to a pattern-making device and a pattern-making method suitable for making a sheet-like material such as leather.

従来から、種々の皮革製品が製造・販売されており、様々な特徴あるデザインを実現するために、表面に模様を形成する方法として種々の技術が用いられている。その技術のひとつが、いわゆる「漉き」であり、漉いた部分で皮革を折り曲げる等して模様を形成する。 Conventionally, various leather products have been manufactured and sold, and various techniques have been used as a method for forming a pattern on the surface in order to realize various characteristic designs. One of the techniques is so-called "squeezing", in which a pattern is formed by bending the leather at the squeezed part.

ここで、例えば特許文献１（特開２００１−１２３２００号公報）には、「皮革の銀面に模様を型押しして、圧縮により得られた凹部と圧縮されなかった凸部からなる模様を銀面に形成する第１工程。型押しされた皮革の凸部を、凹部を消失させない深さの範囲内で削り取り、凸部の銀面を消失させてヌバックを表す第２工程。第２工程の加工を施した皮に水分を含ませることにより、型押しされて圧縮された凹部の圧縮状態を解消してその厚みを復帰させる第３工程。」を含む方法が開示されている（特許文献１、特許請求の範囲）。 Here, for example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2001-123200), "a pattern is embossed on the silver surface of leather, and a pattern composed of a concave portion obtained by compression and an uncompressed convex portion is silver. The first step of forming on the surface. The second step of scraping the convex portion of the embossed leather within a depth range that does not eliminate the concave portion and eliminating the silver surface of the convex portion to represent nubuck. A method including "a third step of eliminating the compressed state of the embossed and compressed recesses and restoring the thickness by impregnating the processed leather with water" is disclosed (Patent Document 1). , Scope of patent claim).

また、例えば特許文献２（実用新案登録第３１９５７５７号公報）には、「皮革の裏面を略直線的に複数箇所に漉き、当該漉きを加えた部分の厚さが１．２ｍｍ以下であることを特徴とする革素材。」や、「皮革の裏面を略直線的に複数箇所に漉き、当該漉きを加えた部分の厚さがそれ以外の部分の厚さの１／２以下であることを特徴とする革素材。」が開示されている。 Further, for example, Patent Document 2 (Utility Model Registration No. 3195757) states that "the back surface of leather is squeezed into a plurality of places substantially linearly, and the thickness of the portion to which the squeezing is added is 1.2 mm or less. Characteristic leather material. ”And“ The back side of the leather is squeezed into multiple places in a substantially straight line, and the thickness of the part to which the squeezing is added is less than 1/2 the thickness of the other parts. The leather material to be used. "

特開２００１−１２３２００号公報Japanese Unexamined Patent Publication No. 2001-123200 実用新案登録第３１９５７５７号公報Utility Model Registration No. 3195757

しかしながら、上記特許文献１の技術は、乳頭層の表面（銀面）及び裏側の起毛面（ヌバック）を有する皮革を用いることが前提とされていて汎用性に劣り、また、型押しで形成された凸部の表面を削り取り、型押しで圧縮された凹部に水分を含ませて元に戻さなければならず煩雑である。 However, the technique of Patent Document 1 is inferior in versatility because it is premised on using leather having a surface (silver surface) and a brushed surface (nubuck) on the back side of the papillary layer, and is formed by embossing. It is complicated because the surface of the convex portion must be scraped off and the concave portion compressed by embossing must be moistened and restored.

また、上記特許文献２の技術は、型を用いず手作業で漉きを入れることを前提としていることから、例えば菱形等の複雑なパターンを形成することはできるものの、大量生産には不向きで到底対応できないという問題がある。 Further, since the technique of Patent Document 2 is premised on manually making a pattern without using a mold, it is possible to form a complicated pattern such as a rhombus, but it is not suitable for mass production. There is a problem that it cannot be dealt with.

そこで、本発明は、皮革等を含む種々のシート状材料に対応可能で汎用性に優れ、例えば種々のデザインの革製品をシンプルな工程で製造可能であり、大量生産に好適なパターン漉き装置及びパターン漉き方法を提供することを目的とする。 Therefore, the present invention can be applied to various sheet-like materials including leather and has excellent versatility. For example, leather products of various designs can be manufactured by a simple process, and a pattern making device and a pattern suitable for mass production can be produced. The purpose is to provide a method of making.

Have found that it is effective to use a mold and a transporting means, and have completed the present invention.

以下、本発明の代表的な実施形態に係るパターン漉き装置及びパターン漉き方法について、図面を参照しながら詳細に説明する。なお、図面は、本発明を概念的に説明するためのものであるから、理解容易のために、必要に応じて寸法、比又は数を誇張又は簡略化して表している場合もあり、本発明はこれらのみに限定されるものではない。 Hereinafter, the pattern-making apparatus and the pattern-making method according to a typical embodiment of the present invention will be described in detail with reference to the drawings. Since the drawings are for conceptually explaining the present invention, the dimensions, ratios or numbers may be exaggerated or simplified as necessary for easy understanding. Is not limited to these.

まず、皮革等のシート状材料に漉きを施す様子について図１を参照しながら説明すると、図１（Ａ）に示すシート状材料１に漉きを入れる場合、切断手段としてナイフやべベラ等の切断刃を有する革漉き工具を用いて、図１（Ｂ−１）に示すように、例えば直線状の漉き溝１ａを形成する（なお、図１（Ｂ−２）は図１（Ｂ−１）に示すシート状材料１の側面図である）。 First, the state of making a sheet-like material such as leather will be described with reference to FIG. 1. When the sheet-like material 1 shown in FIG. 1 (A) is made, a knife, a bevela, or the like is cut as a cutting means. Using a leather-making tool having a blade, for example, a linear making groove 1a is formed as shown in FIG. 1 (B-1) (Note that FIG. 1 (B-2) is shown in FIG. 1 (B-1)). It is a side view of the sheet-like material 1 shown in (1).

そして、図１（Ｃ）に示すように、シート状材料１を漉き溝１ａの部分で容易に折り曲げることができ、外表面に直線状の模様１ｂを形成できるのであるが、この漉き溝１ａの形状や構造を駆使することにより、外表面に種々の模様を有するデザインの、シート状材料からなる製品（例えばカバン等の革製品）を作製できるものの、従来これをシンプルな工程で製造しかつ大量生産に対応することが困難であった。 Then, as shown in FIG. 1C, the sheet-like material 1 can be easily bent at the portion of the squeezing groove 1a, and a linear pattern 1b can be formed on the outer surface. By making full use of the shape and structure, it is possible to manufacture products made of sheet-like materials (for example, leather products such as bags) with designs that have various patterns on the outer surface, but conventionally this is manufactured by a simple process and mass-produced. It was difficult to deal with.

そこで、本発明の代表的な実施形態においては、図２及び３に示すように、シート状材料１と、凸状部で構成された所定のパターン２ａと基部２ｂを有する型２と、の積層体４を、互いに押圧しながら矢印Ｘの向きに搬送し、型２が押圧・積層された状態で、積層体４におけるシート状材料１のうちの、型２と反対側においてパターン２ａに対応して***する部分Ｐを、搬送方向の下流側に設けられた切断刃６で漉く（図３及び図４（Ｂ））。 Therefore, in a typical embodiment of the present invention, as shown in FIGS. 2 and 3, a sheet-like material 1 and a mold 2 having a predetermined pattern 2a composed of convex portions and a base portion 2b are laminated. The bodies 4 are conveyed in the direction of the arrow X while pressing each other, and in a state where the mold 2 is pressed and laminated, the sheet-like material 1 in the laminated body 4 corresponds to the pattern 2a on the side opposite to the mold 2. The raised portion P is strained by a cutting blade 6 provided on the downstream side in the transport direction (FIGS. 3 and 4 (B)).

本実施形態では、シート状材料１と、凸状部で構成された所定のパターン２ａと基部２ｂを有する型２と、の積層体４を、互いに押圧しながら搬送する搬送手段である上側ローラ８ａ及び下側ローラ８ｂ、並びに、搬送手段の下流側に設けられた切断刃６と、を具備するパターン漉き装置１０を用いている。 In the present embodiment, the upper roller 8a, which is a transporting means for transporting the laminated body 4 of the sheet-shaped material 1, the predetermined pattern 2a formed of the convex portion, and the mold 2 having the base portion 2b, while pressing each other. A pattern-making device 10 including a lower roller 8b and a cutting blade 6 provided on the downstream side of the conveying means is used.

詳細に説明すると、本実施形態では、まず、図２（Ａ）及び（Ｂ）に示すように、皮革等のシート状材料１と、凸状部で構成された所定のパターン２ａと基部２ｂを有する型２と、の積層体４を、それぞれ矢印Ｙａ及び矢印Ｙｂの向きに回転する上側ローラ８ａ及び下側ローラ８ｂで挟むようにして、矢印Ｘの向きに搬送する。このとき、積層体４におけるシート状材料１と型２とは互いに押圧されている。 More specifically, in the present embodiment, first, as shown in FIGS. 2 (A) and 2 (B), a sheet-like material 1 such as leather, a predetermined pattern 2a and a base 2b composed of convex portions are formed. The laminated body 4 of the mold 2 and the mold 2 is conveyed in the direction of arrow X so as to be sandwiched between the upper roller 8a and the lower roller 8b that rotate in the directions of arrow Ya and arrow Yb, respectively. At this time, the sheet-like material 1 and the mold 2 in the laminated body 4 are pressed against each other.

ここで、型２は、本発明の効果を損なわない範囲で種々の材料を用いて作製することができる。例えば、凸状部で構成された所定のパターン２ａは、上側ローラ８ａ及び下側ローラ８ｂ等の搬送手段で挟まれた際に、凸状部が形状変化して漉き溝１ａを形成できないという状況にならない程度の強度を有していればよく、例えば各種樹脂、皮革、再生皮革（リサイクルレザー）、木材、金属等で作製されていてよい。 Here, the mold 2 can be produced by using various materials as long as the effects of the present invention are not impaired. For example, when the predetermined pattern 2a composed of the convex portion is sandwiched between the conveying means such as the upper roller 8a and the lower roller 8b, the convex portion changes its shape and the squeezing groove 1a cannot be formed. It suffices to have a strength that does not become, for example, it may be made of various resins, leather, recycled leather (recycled leather), wood, metal, or the like.

また、パターン２ａは、上側ローラ８ａ及び下側ローラ８ｂの間に入って挟まれて搬送され易くかつ型としての役割を確実に果たすという観点から、ある程度の柔軟性を有しているのが好ましい。加工精度を保つために、ゴミ等の有無並びにズレやヨレの様子を目視できるという観点から、透明であってもよい。 Further, it is preferable that the pattern 2a has a certain degree of flexibility from the viewpoint that it is easily sandwiched between the upper roller 8a and the lower roller 8b and is easily transported and plays a role as a mold. .. In order to maintain the processing accuracy, it may be transparent from the viewpoint that the presence or absence of dust and the like and the state of deviation and twist can be visually observed.

パターン２ａを構成する凸状部については、所望する漉き溝１ａのデザインや最終製品の表面に表したい模様に応じて、適宜設計すればよい。例えば凸状部の高さは、シート状材料１の材質、硬さ、上側ローラ８ａ及び下側ローラ８ｂの間の距離等の条件に応じて、確実に漉き溝１ａが形成されるように、当業者であれば適宜選択することができる。 The convex portion forming the pattern 2a may be appropriately designed according to the desired design of the squeezing groove 1a and the pattern to be displayed on the surface of the final product. For example, the height of the convex portion is set so that the squeezing groove 1a is surely formed according to conditions such as the material and hardness of the sheet-like material 1, the distance between the upper roller 8a and the lower roller 8b, and the like. Those skilled in the art can appropriately select it.

また、基部２ｂには、パターン２ａを保持・固定できるものであれば特に制限なく種々の材料を用いることができ、例えば、種々の紙や樹脂シートを用いることができる。なお、型２を構成するパターン２やａと基部２ｂとは、例えば接着剤で互いに接着しておけばよい。また、加工精度を保つために、ゴミ等の有無並びにズレやヨレの様子を目視できるという観点から、透明であってもよい。 Further, various materials can be used for the base 2b without particular limitation as long as the pattern 2a can be held and fixed, and for example, various papers and resin sheets can be used. The patterns 2 and a constituting the mold 2 and the base portion 2b may be adhered to each other with, for example, an adhesive. Further, in order to maintain the processing accuracy, it may be transparent from the viewpoint that the presence or absence of dust and the like and the state of deviation and twist can be visually observed.

そして、矢印Ｘの向きにおける上側ローラ８ａ及び下側ローラ８ｂの下流側には、切断刃６が配置されており、切断刃６は、図２（Ａ）及び（Ｂ）の紙面に略垂直な方向において、シート状材料１の幅と略同一の幅を有している。 A cutting blade 6 is arranged 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 surfaces of FIGS. 2A and 2B. In the direction, it has substantially the same width as the width of the sheet-like material 1.

また、切断刃６は、いわゆる片刃の構造を有しており、片刃の傾斜面が下方を向いている（上方を向いていてもよい。）。切断刃６は両刃でもよく種々の形状を有していてよい。なお、本実施形態は、切断手段としてかかる切断刃６を用いる態様であるが、例えばバンドマシンやスライサー等の漉き割り機等、皮革加工の分野で使用されている各種切断手段を用いることもできる。 Further, the cutting blade 6 has a so-called single-edged structure, and the inclined surface of the single-edged blade faces downward (may be directed upward). The cutting blade 6 may be a double-edged blade and may have various shapes. In this embodiment, the cutting blade 6 is used as the cutting means, but various cutting means used in the field of leather processing such as a band machine, a slicing machine such as a slicer, and the like can also be used. ..

かくして、上側ローラ８ａ及び下側ローラ８ｂによって矢印Ｘの向きに搬送される積層体４は、図２（Ｂ）に示される位置から図３に示される位置に搬送される過程において、押圧・積層された状態の積層体４におけるシート状材料１の一部が、切断刃６で切り取られる（切断される）。 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. 2 (B) to the position shown in FIG. A part of the sheet-like material 1 in the laminated body 4 in the completed state is cut (cut) by the cutting blade 6.

即ち、図３に示されるように、積層体４のうちのシート状材料１において、型２と反対側においてパターン２ａの凸状部に対応して***する部分Ｐを、矢印Ｘの向きにおける下流側に設けられた切断刃６で漉いて、漉き溝１ａが形成される。 That is, as shown in FIG. 3, in the sheet-like material 1 of the laminated body 4, the portion P that rises corresponding to the convex portion of the pattern 2a on the side opposite to the mold 2 is downstream in the direction of the arrow X. A cutting groove 1a is formed by straining with a cutting blade 6 provided on the side.

ここで、図４を参照しながら、積層体４のうちのシート状材料１において、型２と反対側においてパターン２ａの凸状部に対応して***する部分Ｐが切断刃６で切り取られ、漉き溝１ａが形成される様子を詳細に説明する。 Here, referring to FIG. 4, in the sheet-like material 1 of the laminated body 4, the portion P that rises corresponding to the convex portion of the pattern 2a on the side opposite to the mold 2 is cut off by the cutting blade 6. The state in which the squeezing groove 1a is formed will be described in detail.

図４（Ａ）に示すように、積層体４は、シート状材料１と、凸状部で構成された所定のパターン２ａと基部２ｂを有する型２と、を含んでいる。この積層体４を、上側ローラ８ａ及び下側ローラ８ｂで互いに押圧しながら搬送すると、図４（Ｂ）に示すように、パターン２ａの凸状部に対応して下方に***する部分Ｐが形成される。 As shown in FIG. 4A, the laminate 4 includes a sheet-like material 1 and a mold 2 having a predetermined pattern 2a composed of convex portions and a base portion 2b. When the laminated body 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 rises downward corresponding to the convex portion of the pattern 2a is formed. Will be done.

この***する部分Ｐは、切断刃６によって、切断されて切り取られ、図４（Ｃ）に示すように、シート状材料１のうちの型２とは反対側に漉き溝１ａが形成される。切断刃６は、例えば、切断刃６の先端部が図４（Ｂ）において破線で示される位置に沿うように、配置され、部分Ｐを確実に切断するように調整すればよい。 The raised portion P is cut and cut by the cutting blade 6, and as shown in FIG. 4C, a squeezing groove 1a is formed on the side of the sheet-like material 1 opposite to the mold 2. The cutting blade 6 may be arranged, for example, so that the tip end portion of the cutting blade 6 is aligned with the position shown by the broken line in FIG. 4B, and may be adjusted so as to reliably cut the portion P.

本実施形態においては、上記のようなパターン漉き方法及びパターン漉き装置により、所望するパターンを有する型を用いてシート状材料に効率良く漉き溝を形成することができ、続く折り曲げ加工等を経て、種々のデザインを有する革製品等をシンプルな工程で大量に生産することが可能である。 In the present embodiment, the pattern-making method and the pattern-making device as described above can efficiently form a forming groove in the sheet-like material using a mold having a desired pattern, and after a subsequent bending process or the like, the sheet-like material can be efficiently formed. It is possible to mass-produce leather products and the like having various designs by a simple process.

ここで、より具体的な例を挙げる。図５は凸状部で構成された所定のパターン２ａと基部２ｂを有する型２の一具体例の平面図である。また、図６は、図５の型２と上記の本発明のパターン漉き方法及びパターン漉き装置を用いて漉き溝１ａを形成したシート状材料１の平面図である。 Here, a more specific example will be given. FIG. 5 is a plan view of a specific example of the mold 2 having a predetermined pattern 2a composed of convex portions and a base portion 2b. Further, FIG. 6 is a plan view of the sheet-like material 1 in which the forming groove 1a is formed by using the mold 2 of FIG. 5 and the pattern-making method and the pattern-making device of the present invention described above.

この図６のシート状材料１を、漉き溝１ａに沿って折り曲げることにより、図７に示すように、漉き溝１ａに対向する表面側の位置に模様１ｂを有する最終製品（ここでは革製品であるカバン）を得ることができる。 As shown in FIG. 7, the sheet-like material 1 of FIG. 6 is bent along the squeezing groove 1a to have a pattern 1b at a position on the surface side facing the squeezing groove 1a (here, a leather product). You can get a bag).

以上、本発明の代表的な実施形態について説明したが、本発明はこれらのみに限定されるものではない。例えば、上記実施形態においては、漉き溝１ａが最終製品の模様に現れる部分に形成される場合について説明したが、***した部分Ｐをシート状材料１の端部に位置させれば、いわゆるコバ漉きにも適用することができる。換言すると、本発明においては、コバ漉き等の他の漉きを同時に行うことも可能である。 Although typical embodiments of the present invention have been described above, the present invention is not limited to these. For example, in the above embodiment, the case where the squeezing groove 1a is formed in the portion appearing in the pattern of the final product has been described, but if the raised portion P is positioned at the end portion of the sheet-like material 1, so-called edge squeezing is performed. It can also be applied to. In other words, in the present invention, it is also possible to simultaneously perform other making such as edge making.
