Recently, various types of housings are applied to resin molded housings. Decorative material is an indispensable element for differentiating from other products. In such a situation, some companies can freely select a decorative design of a product by applying various decorative materials to the resin molded housing even for the same product.
　樹脂成形ハウジングの加飾方法としては、樹脂シートに塗装、転写、グラビア印刷を施す技術があり（例えば、特許文献１参照）、また、装飾性に優れた繊維（テキスタイル）を含む装飾材をインモールド成形によって樹脂容器の表面に形成した樹脂成形体が提案されている（例えば、特許文献２参照）。この樹脂成形体は、互いに接合された基材フィルム及びテキスタイル素材からなる装飾材が被装飾体の表面に融着されている。装飾材は、一例として、基材フィルムが覆われたテキスタイル素材からなり、基材フィルムはポリエステル樹脂、ナイロン等のポリアミド樹脂、ポリオレフィン樹脂、ポリスチレン樹脂等からなる。 As a method for decorating a resin molded housing, there is a technique for painting, transferring, and gravure printing on a resin sheet (see, for example, Patent Document 1), and a decorative material containing fibers (textiles) with excellent decorative properties is used. A resin molded body formed on the surface of a resin container by molding is proposed (for example, see Patent Document 2). In this resin molded body, a base material film and a decorative material made of a textile material bonded to each other are fused to the surface of the object to be decorated. For example, the decorative material is made of a textile material covered with a base film, and the base film is made of polyester resin, polyamide resin such as nylon, polyolefin resin, polystyrene resin, or the like.
　また、被装飾体に加飾材としてのテキスタイル素材を接着する技術として、テキスタイル素材を金型キャビティ面上に張設した後キャビティ内に溶融樹脂を加圧注入することにより、加飾材に溶融樹脂を浸透させて両者を投錨状態に積層圧着する技術がある（例えば、特許文献３参照）。 In addition, as a technique for bonding textile materials as decorating materials to the body to be decorated, the textile materials are stretched over the mold cavity surface, and then molten resin is injected into the cavities to melt into the decorating materials. There is a technique in which a resin is infiltrated and both are laminated and pressure-bonded in a throwing state (see, for example, Patent Document 3).

　しかしながら、特許文献１の技術では、塗装による加飾は、加飾部が平面的でしかない上に塗装工程で使用される揮発性有機化合物（ＶＯＣ）が健康被害を引き起こし、転写による加飾は、プラスチック成形筐体から塗料が剥離し易い場合が多く、グラビア印刷による加飾は、絵柄毎に金型ロールを準備する必要性から個別少量生産には適していない。 However, in the technology of Patent Document 1, the decoration by painting is not only a flat decoration part, but also the volatile organic compound (VOC) used in the painting process causes health damage, In many cases, the paint is easily peeled off from the plastic molded casing, and the decoration by gravure printing is not suitable for individual small-scale production because of the need to prepare a mold roll for each pattern.
　また、特許文献２の技術では、テキスタイル素材を覆う基材フィルムが耐衝撃性に劣ると共に傷がつき易いのに加えて、インモールド成形時の高温下における耐性が低く且つ被装飾体に対するテキスタイル素材の接着性が劣り、製品のハウジングを形成するには装飾材が融着された被装飾体にさらなるハウジング加工工程を施す必要がある。 In addition, in the technique of Patent Document 2, the base material film covering the textile material is inferior in impact resistance and easily damaged, and the textile material for the object to be decorated is low in resistance at high temperatures during in-mold molding. In order to form a product housing, it is necessary to subject the object to be decorated to which the decorative material has been fused to a further housing processing step.
　特許文献３の技術では、被装飾材に対するテキスタイル素材の密着性が十分でない上に、必ずしも製品の多様化のための多種少量生産性及び各製品への汎用性が考慮されていない。また、特許文献３の技術では、溶融樹脂の加圧注入時にテキスタイル素材に皺がよったり絵柄がゆがんだりし易く量産時の歩留まりが悪い。 In the technology of Patent Document 3, the adhesion of the textile material to the material to be decorated is not sufficient, and the low-volume productivity for diversification of products and the versatility of each product are not always taken into consideration. Further, in the technique of Patent Document 3, the textile material is liable to wrinkle or the pattern is distorted when the molten resin is injected under pressure, and the yield during mass production is poor.
　本発明の目的は、テキスタイル層の基盤樹脂層に対する密着性及びテキスタイル層の表面の耐衝撃性及び擦過性が優れ、加えてテキスタイル層の皺の発生や絵柄のゆがみがないテキスタイル／樹脂積層構造ハウジングを提供すると共に、テキスタイル層の基盤樹脂層に対する密着性及びテキスタイル層の表面の耐衝撃性及び擦過性を向上させ、加えてテキスタイル層の皺の発生や絵柄のゆがみを無くすことができるテキスタイル／樹脂積層構造ハウジングの製造装置を提供することにある。 The object of the present invention is to provide a textile / resin laminated structure housing which is excellent in adhesion of the textile layer to the base resin layer, impact resistance and scratch resistance of the surface of the textile layer, and in addition, there is no generation of wrinkles in the textile layer or distortion of the pattern.

　図２は、図１の線ＩＩ−ＩＩに沿うテキスタイル／樹脂積層構造ハウジングの断面図である。 FIG. 2 is a cross-sectional view of the textile / resin laminate housing taken along line II-II in FIG.
　ハウジング１は、透明アクリルシート層２と、透明アクリルシート層２に接着剤３を介して接着されたテキスタイル層４と、テキスタイル層４の各繊維の隙間に浸潤しつつテキスタイル層４に固着された基盤樹脂層５とを備える。 The housing 1 is fixed to the textile layer 4 while infiltrating the gap between the fibers of the transparent acrylic sheet layer 2, the textile layer 4 adhered to the transparent acrylic sheet layer 2 via the adhesive 3, and the textile layer 4. And a base resin layer 5.
　透明アクリルシート層２は、エラストマーを含有する厚さ０．１~０．４ｍｍのソフトアクリルシートからなり、テキスタイル層４をコーティングする機能とメカニカルダメージに対する耐性（耐衝撃性、耐擦過性）を有する。透明アクリルシート層２は、例えば、株式会社クラレが製造販売するソフトアクリルシート（商品名：クラリティ）、又は住友化学工業株式会社が製造販売するソフトアクリルシート（商品名：テクノロイ）が好ましい。これらのソフトアクリルシートは耐衝撃性及び耐擦過性が優れている。上記エラストマーは、ソフトアクリル１００重量部に対する混練率は、１０~６０重量部である。また、ソフトアクリルシート（商品名：クラリティ）に含有されるエラストマーは、アクリルゴム、ニトリルゴム、イソプレンゴムの群から選択された１つの素材を含む合成ゴムからなり、ソフトアクリルシート（商品名：テクノロイ）は、分子内にゴム成分を含有するＰＭＭＡ（ポリメタクリルアクリレート）からなる。 The transparent acrylic sheet layer 2 is made of a soft acrylic sheet having a thickness of 0.1 to 0.4 mm containing an elastomer, and has a function of coating the textile layer 4 and resistance to mechanical damage (impact resistance, scratch resistance). . The transparent acrylic sheet layer 2 is preferably, for example, a soft acrylic sheet (trade name: Clarity) manufactured and sold by Kuraray Co., Ltd. or a soft acrylic sheet (trade name: Technoloy) manufactured and sold by Sumitomo Chemical Co., Ltd. These soft acrylic sheets are excellent in impact resistance and scratch resistance. The above-mentioned elastomer has a kneading rate of 10 to 60 parts by weight with respect to 100 parts by weight of soft acrylic.

The soft acrylic sheet (trade name: Technoloy) ) Consists of PMMA (polymethacrylate) containing a rubber component in the molecule.
　テキスタイル層４は、織物、編物等の繊維製品を含むテキスタイルからなる。このテキスタイルとしては、ポリエステル織物、編物、レース、カーボン繊維が挙げられる。 The textile layer 4 is made of textile including fiber products such as woven fabric and knitted fabric. Examples of the textile include polyester fabric, knitted fabric, lace, and carbon fiber.
　このテキスタイルは、さまざまなデザインが容易に得られると共に繊維生地の立体感がそのまま現出される。また、テキスタイルの使用は、ハウジング１のデザイン性の自由度を高めることができるのに加えて、ハウジング１の強度を高める効果を有する。 This textile allows various designs to be easily obtained, and the three-dimensional feeling of the fiber fabric appears as it is. Further, the use of the textile has the effect of increasing the strength of the housing 1 in addition to increasing the degree of freedom of design of the housing 1.
　接着剤３は、透明アクリルシート層２とテキスタイル層４の双方を互いに接着し易くし得、しかも、粘度が低く、気泡を逃すことができるほどに硬化速度が遅い特性を有するのが好ましい。接着剤は、ポリウレタン系接着剤、アクリル系接着剤、エポキシ樹脂系接着剤、及び塩化ビニル系接着剤の群から選択された１つの素材からなる。 It is preferable that the adhesive 3 has a characteristic that it can easily adhere both the transparent acrylic sheet layer 2 and the textile layer 4 to each other, and has a low viscosity and a curing speed that is slow enough to allow bubbles to escape. The adhesive is made of one material selected from the group of polyurethane adhesives, acrylic adhesives, epoxy resin adhesives, and vinyl chloride adhesives.

It is injected into a die die 22 shown in FIG. 3 that will be described later, and is fixed to the textile layer 4 while infiltrating the gaps between the fibers of the textile layer 4 (FIG. 3). The base resin layer 5 is more firmly fixed to the textile layer 4 due to shrinkage of the textile layer 4 and the base resin layer 5 during cooling and solidification.
　図１のハウジング１によれば、基盤樹脂層５がテキスタイル層４の各繊維の隙間に浸潤しつつテキスタイル層４に固着されているので、アンカー効果により、テキスタイル層４の基盤樹脂層５に対する密着性を向上させると共にテキスタイル層４の各繊維がハウジング１の強度を向上させることができ、加えて、透明アクリルシート層２により、リモコン装置用上部ケーシングの耐衝撃性及び耐擦過性を向上させると共に基盤樹脂層５の射出成形時にテキスタイル層４の皺の発生及び絵柄のゆがみを無くすことができる。また、図１のハウジングによれば、ハウジング１の表面の絵柄をテキスタイル層４の変更によりさまざまに選択することができる。 According to the housing 1 of FIG. 1, since the base resin layer 5 is fixed to the textile layer 4 while infiltrating the gaps between the fibers of the textile layer 4, the textile layer 4 adheres to the base resin layer 5 by an anchor effect. The fibers of the textile layer 4 can improve the strength of the housing 1 and the transparent acrylic sheet layer 2 improves the impact resistance and scratch resistance of the upper casing for the remote control device. Generation of wrinkles in the textile layer 4 and distortion of the pattern can be eliminated during the injection molding of the base resin layer 5. Further, according to the housing of FIG. 1, the pattern on the surface of the housing 1 can be variously selected by changing the textile layer 4.

　図１のハウジング１は、透明アクリルシート層２を表とする逆舟形構造としたが、このハウジング１は、基盤樹脂層５を表とする逆舟形構造としてもよい。これのハウジング１は、用途がリモコン構造上部ケーシングに限定されない。 Although the housing 1 in FIG. 1 has an inverted boat structure with the transparent acrylic sheet layer 2 as the front, the housing 1 may have an inverted boat structure with the base resin layer 5 as the front. The use of the housing 1 is not limited to the upper casing of the remote control structure.
　図３は、本発明の実施の形態に係るテキスタイル／樹脂積層構造ハウジングの製造装置を説明するのに用いられる図である。 FIG. 3 is a diagram used for explaining a textile / resin laminated housing manufacturing apparatus according to an embodiment of the present invention.
　図３では、プレス機により工程Ｉ及びＩＩが実施されると共に、射出成形機により工程ＩＩＩ及びＩＶが実施される。 In FIG. 3, steps I and II are performed by a press machine, and steps III and IV are performed by an injection molding machine.
　まず、接着剤３を介して互いに接着された透明アクリルシート層２及びテキスタイル層２の積層体を準備し、図３の工程Ｉにおいて、透明アクリルシート層２及びテキスタイル層４の積層体をテキスタイル層４を表にしてプレス機のメス金型１０（固定金型）の上に載置する。この積層体は、予め所定の形状に切断されていてもよい。また、接着剤３は、ポリウレタン系接着剤、アクリル系接着剤、エポキシ樹脂系接着剤、及び塩化ビニル系接着剤の群から選択された１つの素材からなる。 First, a laminate of the transparent acrylic sheet layer 2 and the textile layer 2 bonded to each other via the adhesive 3 is prepared. In Step I of FIG. 3, the laminate of the transparent acrylic sheet layer 2 and the textile layer 4 is a textile layer. Table 4 is placed on a female die 10 (fixed die) of the press machine. This laminated body may be cut into a predetermined shape in advance. The adhesive 3 is made of one material selected from the group of polyurethane adhesives, acrylic adhesives, epoxy resin adhesives, and vinyl chloride adhesives.
　次いで、工程ＩＩにおいて、工程Ｉで載置された透明アクリルシート２及びテキスタイル層４の積層体をメス金型１０の中に押し込むようにプレス機のオス金型１１（可動金型）をメス金型１０に向かって移動する。これにより、透明アクリルシート層２及びテキスタイル層４の積層体をメス金型１０及びオス金型１１により規定される形状に成形した後、この成形された積層体はプレス機から取り出される。このとき、成形された積層体の周囲をレーザカッタや切断用金型（切断ユニット）で切断してバリ取りを行ってもよい。 Next, in step II, the male die 11 (movable die) of the press machine is moved to the female die so that the laminate of the transparent acrylic sheet 2 and the textile layer 4 placed in step I is pushed into the female die 10. Move toward the mold 10. Thereby, after shape | molding the laminated body of the transparent acrylic sheet layer 2 and the textile layer 4 in the shape prescribed | regulated with the female metal mold | die 10 and the male metal mold | die 11, this molded laminated body is taken out from a press machine. At this time, the periphery of the formed laminated body may be deburred by cutting with a laser cutter or a cutting die (cutting unit).
　続いて、図３の工程ＩＩＩにおいて、プレス機で成形された透明アクリルシート層２及びテキスタイル層４の積層体をテキスタイル層４を表にしてメス金型２２（他の固定金型）内に装着した上で、金型ダイ２２内に受容された積層体に向けて射出成形オス金型１２（射出成型金型）を移動すると共に、射出機２０の射出孔２０ａを射出成形オス金型１２の射出成形孔１２ａに押し当てた上で、射出スクリュー２１を時計回りに回転させてタンク３０内の基盤樹脂層５の原料３１を当該積層体と射出成形オス金型１２とで規定される空間に射出する。このとき、基盤樹脂層５の原料３１はテキスタイル層４の各繊維の隙間に浸潤し、原料３１の冷却固化時におけるテキスタイル層４及び基盤樹脂層５の収縮によりテキスタイル層４との固着がより強固になる。 Subsequently, in Step III of FIG. 3, the laminate of the transparent acrylic sheet layer 2 and the textile layer 4 formed by a press machine is mounted in the female mold 22 (other fixed mold) with the textile layer 4 as a table. Then, the injection molding male mold 12 (injection molding mold) is moved toward the laminated body received in the mold die 22, and the injection hole 20 a of the injection machine 20 is moved through the injection molding male mold 12. After pressing against the injection molding hole 12a, the injection screw 21 is rotated clockwise to feed the raw material 31 of the base resin layer 5 in the tank 30 into the space defined by the laminate and the injection molding male mold 12. Eject. At this time, the raw material 31 of the base resin layer 5 is infiltrated into the gaps between the fibers of the textile layer 4, and the textile layer 4 and the base resin layer 5 are more firmly fixed to each other due to the shrinkage of the textile layer 4 and the base resin layer 5 when the raw material 31 is cooled and solidified. become.
　最後に、工程ＩＶにおいて、射出成形された基盤樹脂層５が冷却して固化した後、射出機２０及び射出成形オス金型１２がメス金型１０から離間されて、ハウジング１が取り出される。 Finally, in step IV, after the injection-molded base resin layer 5 is cooled and solidified, the injection machine 20 and the injection-molded male mold 12 are separated from the female mold 10 and the housing 1 is taken out.
　メス金型１０及びオス金型１１はプレス機を構成すると共に、メス金型２２、射出成形オス金型１２、及び射出機２０は射出成形機を構成し、プレス機及び射出成形機はハウジング１の製造装置を構成する。変形例として、プレス機と射出成形機とが一体となっていて、メス金型１０がメス金型２２として使用されてもよい。この場合は、メス金型１０の中で成形された透明アクリルシート層２及びテキスタイル層４の積層体に向けて射出成形オス金型１２が移動される。 The female mold 10 and the male mold 11 constitute a press machine, and the female mold 22, the injection molding male mold 12 and the injection machine 20 constitute an injection molding machine. The press machine and the injection molding machine are the housing 1. The manufacturing apparatus is configured. As a modification, the press machine and the injection molding machine may be integrated, and the female die 10 may be used as the female die 22. In this case, the injection molding male mold 12 is moved toward the laminated body of the transparent acrylic sheet layer 2 and the textile layer 4 molded in the female mold 10.
　図３のテキスタイル／樹脂積層構造ハウジングの製造装置によれば、工程ＩＩＩにおいて、基盤樹脂層５の原料３１がテキスタイル層４の各繊維の隙間に浸潤し、原料３１の冷却時時におけるテキスタイル層４及び基盤樹脂層５の収縮によりテキスタイル層４との固着がより強固になるのに加えて、ハウジング１の製造工程を簡略化させると共に、表面コーティング塗装工程を省くことができる。さらに、基盤樹脂層５の素材として、高温でしか成形できないポリカーボネートを用いることができる。 According to the textile / resin laminated housing manufacturing apparatus of FIG. 3, in step III, the raw material 31 of the base resin layer 5 infiltrates into the gaps between the fibers of the textile layer 4, and the textile layer 4 when the raw material 31 is cooled. Further, the shrinkage of the base resin layer 5 makes the fixing to the textile layer 4 stronger, and in addition, the manufacturing process of the housing 1 can be simplified and the surface coating process can be omitted. Furthermore, polycarbonate that can be molded only at high temperatures can be used as the material of the base resin layer 5.
　また、図３のテキスタイル／樹脂積層構造ハウジングの製造装置によれば、テキスタイル層４の基盤樹脂層５に対する密着性を向上させると共に、透明アクリル層２によって、テキスタイル層４の表面の耐衝撃性及び擦過性を向上させ、加えて基盤樹脂層５の射出成形時にテキスタイル層４の皺の発生や絵柄のゆがみを無くすことができる。 In addition, according to the textile / resin laminated housing manufacturing apparatus of FIG. 3, the adhesiveness of the textile layer 4 to the base resin layer 5 is improved, and the impact resistance of the surface of the textile layer 4 is improved by the transparent acrylic layer 2. Scratch can be improved, and in addition, generation of wrinkles in the textile layer 4 and distortion of the pattern can be eliminated when the base resin layer 5 is injection molded.
