Description

テキスタイル／樹脂積層構造ハウジング及びその製造装置Textile / resin laminated structure housing and manufacturing apparatus thereof
　本発明は、テキスタイル／樹脂積層構造ハウジング及びその製造装置に関し、特に、基盤樹脂層の上にテキスタイル層が積層されたテキスタイル／樹脂積層構造ハウジング及びその製造装置に関する。 The present invention relates to a textile / resin laminated housing and a manufacturing apparatus thereof, and more particularly, to a textile / resin laminated housing in which a textile layer is laminated on a base resin layer and a manufacturing apparatus thereof.
　電子機器や家電等のハウジング及び自動車内装品のハウジングの技術分野において、そのハウジングは、外面に加飾材が積層された樹脂成形によって作られる場合が多く、近年、樹脂成形ハウジングに施されるさまざまな加飾材が他の製品からの差別化に欠かせない要素となっている。このような状況において、一部の企業は、同一製品でも、樹脂成形ハウジングに多様な加飾材を施すことで顧客が自由に製品の加飾デザインを選択することができるようになっている。 In the technical field of housings for electronic devices, home appliances, etc. and housings for automobile interior parts, the housings are often made by resin molding in which a decorative material is laminated on the outer surface. 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、基材フィルムの素材がポリエステル樹脂、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. As an example, the decorative material is made of a textile material covered with a base film, and the base material is made of a polyester resin, a polyamide resin such as nylon, a polyolefin resin, a 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.

Have.
　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、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 includes a textile layer 4 and a base resin layer 5 fixed to the textile layer 4 while infiltrating the gaps between the fibers of the textile layer 4.
　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.
　基盤樹脂層５は、熱可塑性合成樹脂、好ましくは射出成形用合成樹脂からなり、具体的には、ＡＢＳ（アクリルブチルスチレン）樹脂、ＰＣ（ポリカーボネート）樹脂、ＡＢＳ−ＰＣ樹脂、ＰＭＭＡ（ポリメタクリルアクリレート）樹脂（アクリル樹脂）の群から選択された１つの素材、好ましくはＡＢＳ樹脂からなり、厚さは、製品に応じて任意に設定され、本実施の形態では、約２ｍｍである。基盤樹脂層５の原料は、後述する図３の射出成形機２０で加熱溶融され、後述するように、Ａ−ＰＥＴシート（詳細は後述する）が熱圧着されたテキスタイル層４の熱圧着体がテキスタイル層４を表にして装着された後述する図３における金型ダイ２２の中に射出されて、テキスタイル層４の各繊維の隙間に浸潤しながらテキスタイル層４に固着されている（図３）。基盤樹脂層５は、冷却固化時におけるテキスタイル層４と基盤樹脂層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っている。 The base resin layer 5 is made of a thermoplastic synthetic resin, preferably a synthetic resin for injection molding, and specifically includes ABS (acrylbutyl styrene) resin, PC (polycarbonate) resin, ABS-PC resin, PMMA (polymethacrylate acrylate). ) One material selected from the group of resins (acrylic resins), preferably an ABS resin, and the thickness is arbitrarily set according to the product, and in this embodiment is about 2 mm.

　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。最後に、適宜な方法により工程Ｖ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. Finally, Step V is performed by an appropriate method.
　まず、後述するＡ−ＰＥＴシート２が熱圧着されたテキスタイル層４の熱圧着体を準備し、図３の工程Ｉにおいて、Ａ−ＰＥＴシート２及びテキスタイル層４の熱圧着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。この熱圧着体は、予め所定の形状に切断されていてもよい。 First, a thermocompression body of a textile layer 4 to which an A-PET sheet 2 described later is thermocompression bonded is prepared, and in step I of FIG. The table is placed on the female die 10 (fixed die) of the press machine. This thermocompression bonded body may be cut into a predetermined shape in advance.
　Ａ−ＰＥＴシート２は、非晶質ポリエチレンテレフタレートからなる。これにより、Ａ−ＰＥＴシート２をテキスタイル層４に積層する際に接着剤を不要とすることができる。 A-PET sheet 2 is made of amorphous polyethylene terephthalate. Thereby, when laminating | stacking the A-PET sheet 2 on the textile layer 4, an adhesive agent can be made unnecessary.
　次いで、工程ＩＩにおいて、工程Ｉで載置されたＡ−ＰＥＴシート２及びテキスタイル層４の熱圧着体をメス金型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、Ａ−ＰＥＴシート２及びテキスタイル層４の熱圧着体をメス金型１０及びオス金型１１により規定される形状に成形し、この後、成形された熱圧着体がプレス機から取り出される。このとき、成形された熱圧着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 pressed so as to push the thermocompression-bonded body of the A-PET sheet 2 and the textile layer 4 placed in step I into the female die 10. Move toward the female mold 10. Thereby, the thermocompression-bonded body of the A-PET sheet 2 and the textile layer 4 is formed into a shape defined by the female mold 10 and the male mold 11, and thereafter, the formed thermocompression-bonded body is taken out from the press machine. . At this time, the periphery of the formed thermocompression bonded 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Ａ−ＰＥＴシート２及びテキスタイル層４の熱圧着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内に受容された熱圧着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、射出成形機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を当該熱圧着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と基盤樹脂層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 thermocompression bonded body of the A-PET sheet 2 and the textile layer 4 formed by a press machine is placed in the female die 22 (other fixed die) with the textile layer 4 as a table. After mounting, the injection molding male mold 12 (injection molding mold) is moved toward the thermocompression body received in the mold die 22, and the injection hole 20a of the injection molding machine 20 is moved through the injection molding male mold. After pressing against the injection molding hole 12 a of the mold 12, the injection screw 21 is rotated clockwise to define the raw material 31 of the base resin layer 5 in the tank 30 by the thermocompression body and the injection molding male mold 12. Is injected into the space. At this time, 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 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.
　次いで、工程ＩＶにおいて、射出成形された基盤樹脂層５の原料３１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。 Next, in Step IV, after the raw material 31 of 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. .
　最後に、Ａ−ＰＥＴシート２を剥がして、所望のテキスタイル／樹脂積層構造ハウジング１が完成する。 Finally, the A-PET sheet 2 is peeled off to complete the desired textile / resin laminated structure housing 1.
　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.

In addition to the firmness of the substrate layer 5 and the textile layer 4 being fixed, 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、装飾性に優れたテキスタイル層４の基盤樹脂層５に対する密着性を向上させ且つ基盤樹脂層５の射出成形時にテキスタイル層４に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 adhesion of the textile layer 4 having excellent decorativeness to the base resin layer 5 is improved, and the textile layer 4 is formed on the base resin layer 5 during injection molding.
