Abstract

In this carrier-film-equipped gasket comprising a combination between a rubber-only type gasket main body and a resinous carrier film holding the gasket main body, the carrier film can be removed readily when removing the carrier film from the gasket main body even if the gasket main body is adhered to the carrier film. In order to achieve this objective, the invention comprises: performing the step of peeling the carrier film from the gasket main body against an adhesive force in a state in which the gasket main body is fixed onto a base; and, as a pre-step to this peeling step, pressing the gasket main body from the carrier film side using a press device, thereby diminishing the adhesion surface area between the gasket main body and the carrier film; and performing the peeling step in this reduced state of the adhesion surface area.

Description

キャリアフィルム付きガスケットの取り扱い方法Handling method of gasket with carrier film
　本発明は、シール技術に係るガスケットに関し、更に詳しくは、ラバーオンリータイプのガスケット本体およびこのガスケット本体を保持する樹脂製のキャリアフィルムの組み合わせよりなるキャリアフィルム付きガスケットにおいてガスケット本体からキャリアフィルムを粘着力に抗して取り外すためのキャリアフィルム付きガスケットの取り扱い方法に関する。本発明のガスケットは例えば、燃料電池用ガスケットとして用いられ、またはその他の用途の一般ガスケットとして用いられる。 The present invention relates to a gasket according to a sealing technique, and more specifically, in a gasket with a carrier film, which is a combination of a rubber-only type gasket main body and a resin carrier film that holds the gasket main body, the carrier film is adhered to the gasket main body. The present invention relates to a method of handling a gasket with a carrier film for removal against the erosion. The gasket of the present invention is used, for example, as a fuel cell gasket or as a general gasket for other uses.
　燃料電池用ガスケットには、ゴム状弾性体（ラバー）製のガスケット単品よりなるラバーオンリータイプのガスケット、ゴム状弾性体製のガスケットをセパレータに一体成形したセパレータ一体ガスケット、ゴム状弾性体製のガスケットをＧＤＬ（ガス拡散層）に一体成形したＧＤＬ一体ガスケット等さまざまな構成のガスケットがある。 Gaskets for fuel cells include rubber-only gaskets made of a single rubber-like elastic (rubber) gasket, a separator-integrated gasket in which a rubber-like elastic gasket is integrally molded with a separator, and a rubber-like elastic gasket. There are various types of gaskets such as a GDL integrated gasket formed integrally with GDL (gas diffusion layer).
　これらのガスケットはそれぞれ特徴を有しているが、近年、低コスト化の要求が強いことから、この要求を満足できるラバーオンリータイプのガスケットが注目されている。 These gaskets have their respective characteristics, but since there is a strong demand for cost reduction in recent years, rubber-only type gaskets that can satisfy this demand are attracting attention.
　ラバーオンリータイプのガスケットは例えば、図１３に示すように構成されている。 Rubber-only type gaskets are configured as shown in FIG. 13, for example.
　すなわち、ガスケット１１の全体として平面状（平板状）とされ、燃料電池の反応面の周りを全周に亙ってシールするための外周シール部１２が平面長方形の枠状に設けられている。また、燃料電池の反応面と各マニホールド部を仕切る必要があることから、外周シール部１２の長手方向両端部にそれぞれ内側シール部１３が一体に設けられている。ガスケット１１の断面形状は図１３（Ｂ）に示すように例えば、断面円形とされている。 That is, the gasket 11 as a whole has a flat shape (a flat plate shape), and an outer peripheral seal portion 12 for sealing around the reaction surface of the fuel cell over the entire circumference is provided in a flat rectangular frame shape. Moreover, since it is necessary to partition the reaction surface of the fuel cell and each manifold portion, inner seal portions 13 are integrally provided at both ends in the longitudinal direction of the outer peripheral seal portion 12. The cross-sectional shape of the gasket 11 is, for example, a circular cross section as shown in FIG.
特開２０１４－６０１３３号公報（図１等におけるガスケット３参照）JP 2014-60133 A (refer to gasket 3 in FIG. 1 and the like)
　しかしながらこのラバーオンリータイプの燃料電池用ガスケット１１には、以下の点で更なる改良の余地がある。 However, this rubber-only type gasket 11 for fuel cells has room for further improvement in the following points.
　すなわちこの燃料電池用ガスケット１１は一般に、平面外形を４００ｍｍ×３００ｍｍ程度の大きさとされる一方でその断面形状（線径）を１ｍｍ乃至数ｍｍ程度と小さく設定されている。したがって搬送時やスタッキング時にガスケット１１単体では捩れが生じやすいものであって、その取扱い作業性（ハンドリング性）が良くない。 That is, this fuel cell gasket 11 is generally set to have a planar outer shape of about 400 mm × 300 mm, while its cross-sectional shape (wire diameter) is set to be as small as about 1 mm to several mm. Accordingly, the gasket 11 alone is likely to be twisted during conveyance or stacking, and its handling workability (handling property) is not good.
　そこで、本願出願人は先に図１４に示すように、ラバーオンリータイプのガスケット本体３１と、このガスケット本体３１を保持する樹脂製のキャリアフィルム４１との組み合わせよりなるキャリアフィルム付きガスケット２１を開発・提案しており、このキャリアフィルム付きガスケット２１によればラバーオンリータイプのガスケット本体３１がこれよりも強度の高いキャリアフィルム４１によって保持されるため、捩れが生じにくく、よって取扱い作業性を向上させることができる。 Accordingly, the applicant of the present application has previously developed a gasket 21 with a carrier film comprising a combination of a rubber-only type gasket main body 31 and a resin carrier film 41 holding the gasket main body 31 as shown in FIG. According to the proposed gasket 21 with a carrier film, the rubber-only type gasket main body 31 is held by the carrier film 41 having a higher strength, so that it is difficult to cause twisting, thereby improving the handling workability. Can do.
　ガスケット本体３１は、図１３のガスケット１１と同様に、全体として平面状（平板状）とされ、燃料電池の反応面の周りを全周に亙ってシールする外周シール部３２が平面長方形の枠状に設けられている。また、燃料電池の反応面と各マニホールド部を仕切るため外周シール部３２の長手方向両端部にそれぞれ内側シール部３３が一体に設けられている。ガスケット本体３１の断面形状は図１４（Ｂ）に示すように例えば、断面円形とされている。一方、キャリアフィルム４１は、ガスケット本体３１よりも一回り大きな平面長方形とされた樹脂フィルムよりなり、その平面上に、ガスケット本体３１を保持するための立体形状よりなるガスケット保持部４２が成形されている。 The gasket main body 31 is generally flat (flat) like the gasket 11 of FIG. 13, and an outer peripheral seal portion 32 that seals the entire periphery of the reaction surface of the fuel cell is a flat rectangular frame. It is provided in the shape. In addition, inner seal portions 33 are integrally provided at both ends in the longitudinal direction of the outer peripheral seal portion 32 to partition the reaction surface of the fuel cell and each manifold portion. The cross-sectional shape of the gasket body 31 is, for example, a circular cross section as shown in FIG. On the other hand, the carrier film 41 is made of a resin film having a flat rectangular shape that is slightly larger than the gasket body 31, and a gasket holding portion 42 having a three-dimensional shape for holding the gasket body 31 is formed on the plane. Yes.
　このキャリアフィルム付きガスケット２１は、以下のようにして製造する。製造には、ラバーオンリータイプのガスケット本体３１を射出成形する金型を用いることができる。 This gasket 21 with a carrier film is manufactured as follows. For the production, a mold for injection molding the rubber-only type gasket main body 31 can be used.
　工程としては先ず、所定の大きさの平面形状に裁断した平面状のキャリアフィルム４１を用意し、図１５（Ａ）に示すように、このキャリアフィルム４１を金型５１のパーティング部５４に挟み込んだ状態で金型５１を型締めする。金型５１は上型（一方の分割型）５２および下型（他方の分割型）５３の組み合わせよりなり、両型５２，５３のパーティング部５４にそれぞれキャビティ部５５が一部ずつ対応して設けられている。キャリアフィルム４１は当初その全面が平面状であるため、キャビティ部５５内を横切る状態とされる。 As a process, first, a planar carrier film 41 cut into a planar shape of a predetermined size is prepared, and the carrier film 41 is sandwiched between parting portions 54 of a mold 51 as shown in FIG. In this state, the mold 51 is clamped. The mold 51 is composed of a combination of an upper mold (one split mold) 52 and a lower mold (the other split mold) 53, and the cavity portions 55 respectively correspond to the parting portions 54 of both molds 52 and 53. Is provided. Since the entire surface of the carrier film 41 is initially flat, the carrier film 41 is in a state of crossing the cavity portion 55.
　次いで、図１５（Ｂ）に示すように、キャビティ部５５へガスケット本体３１を成形するための成形材料を充填し加熱する等して、ガスケット本体３１を成形する。キャビティ部５５へ成形材料を充填したとき、キャリアフィルム４１はその平面上一部が成形材料充填圧力によって下型５３のキャビティ部５５の内面に押し付けられ、キャビティ部５５の内面に沿ったかたちに変形（塑性変形）し、これにより立体形状よりなるガスケット保持部４２が成形される。 Next, as shown in FIG. 15B, the gasket body 31 is molded by filling the cavity portion 55 with a molding material for molding the gasket body 31 and heating. When the cavity material 55 is filled with the molding material, the carrier film 41 is partially pressed on the inner surface of the cavity portion 55 of the lower mold 53 by the molding material filling pressure, and deformed along the inner surface of the cavity portion 55. (Plastic deformation), thereby forming a gasket holding portion 42 having a three-dimensional shape.
　次いで、図１５（Ｃ）に示すように、ガスケット本体３１の成形後、型開きし、図１５（Ｄ）に示すように、ガスケット本体３１およびキャリアフィルム４１を同時に金型５１から取り出す。取り出したガスケット本体３１およびキャリアフィルム４１は、ガスケット本体３１がキャリアフィルム４１によって保持された組み合わせ状態とされ、この組み合わせ状態で製品の搬送や保管などを行う。キャリアフィルム４１によって保持されたガスケット本体３１には捩れ等が生じにくく、よってガスケット本体３１を単品で取り扱う場合よりも取扱い作業性が向上する。 Next, as shown in FIG. 15C, after the gasket body 31 is molded, the mold is opened, and the gasket body 31 and the carrier film 41 are simultaneously taken out from the mold 51 as shown in FIG. The taken-out gasket main body 31 and carrier film 41 are in a combined state in which the gasket main body 31 is held by the carrier film 41, and products are transported and stored in this combined state. The gasket main body 31 held by the carrier film 41 is less likely to be twisted and the like, so that the handling workability is improved as compared with the case where the gasket main body 31 is handled as a single item.
　ガスケット本体３１を燃料電池スタックに組み付ける際には、ガスケット本体３１からキャリアフィルム４１を取り外し、ガスケット本体３１のみを組み付ける。 When assembling the gasket body 31 to the fuel cell stack, the carrier film 41 is removed from the gasket body 31 and only the gasket body 31 is assembled.
　ガスケット本体３１からキャリアフィルム４１を取り外す際には例えば図１６（Ａ）（Ｂ）に示すように、ガスケット本体３１をベースとしての真空引き装置６１の吸着部６２にセットし、真空引き（矢印Ｓ）を行ってガスケット本体３１を固定（吸着）させつつ、この状態でガスケット本体３１からキャリアフィルム４１を取り外す。このときキャリアフィルム４１はガスケット本体３１に対し非接着であるために容易に取り外せるはずであるが、ガスケット本体３１がその材質上の特性などからして表面に粘着性を備えていてキャリアフィルム４１に対し粘着していると、ガスケット本体３１からキャリアフィルム４１を強く引き剥がさなければならず、取り外しが困難となる。 When the carrier film 41 is removed from the gasket body 31, for example, as shown in FIGS. 16A and 16B, the gasket body 31 is set on the suction portion 62 of the vacuuming device 61 using the base as the base, and vacuuming (arrow S) is performed. In this state, the carrier film 41 is removed from the gasket body 31 while the gasket body 31 is fixed (adsorbed). At this time, since the carrier film 41 is not bonded to the gasket body 31, it should be easily removable. However, the gasket body 31 has adhesiveness on the surface due to its material characteristics and the like. If it adheres, the carrier film 41 must be strongly peeled off from the gasket body 31, which makes it difficult to remove.
　そこで、本発明は以上の点に鑑みて、ラバーオンリータイプのガスケット本体およびガスケット本体を保持する樹脂製のキャリアフィルムの組み合わせよりなるキャリアフィルム付きガスケットにおいてガスケット本体からキャリアフィルムを取り外す際に、ガスケット本体がキャリアフィルムに粘着していてもキャリアフィルムを容易に取り外すことができるキャリアフィルム付きガスケットの取り扱い方法を提供することを目的とする。 Therefore, in view of the above, the present invention provides a gasket body when removing a carrier film from a gasket body in a gasket with a carrier film made of a combination of a rubber-only type gasket body and a resin carrier film that holds the gasket body. An object of the present invention is to provide a method of handling a gasket with a carrier film, which can easily remove the carrier film even if it adheres to the carrier film.
　上記目的を達成するため、本発明のガスケットの取り扱い方法は、ラバーオンリータイプのガスケット本体および前記ガスケット本体を保持する樹脂製のキャリアフィルムの組み合わせよりなるキャリアフィルム付きガスケットにおいて前記ガスケット本体から前記キャリアフィルムを取り外す方法であって、前記ガスケット本体をベースに固定した状態で前記ガスケット本体から前記キャリアフィルムを粘着力に抗して剥離させる工程を実施し、前記剥離工程の前工程として、プレス装置にて前記キャリアフィルム側から前記ガスケット本体を押圧することで前記ガスケット本体および前記キャリアフィルムの粘着面積を縮小し、この粘着面積縮小の状態で前記剥離工程を実施することを特徴とする。 In order to achieve the above object, a method for handling a gasket according to the present invention comprises a rubber-only type gasket body and a carrier film with a carrier film comprising a combination of a resin carrier film holding the gasket body and the carrier film from the gasket body. In the state where the gasket body is fixed to the base, the carrier film is peeled off from the gasket body against the adhesive force, and as a pre-process of the peeling process, a press device is used. The pressure-sensitive adhesive area of the gasket main body and the carrier film is reduced by pressing the gasket main body from the carrier film side, and the peeling step is performed in a state where the pressure-sensitive adhesive area is reduced.
　上記構成を備える本発明の取り扱い方法では、ガスケット本体をベースに固定した状態でガスケット本体からキャリアフィルムを粘着力に抗して剥離させる工程を実施し、その前工程（前処理工程）として所定の手順によってガスケット本体およびキャリアフィルムの粘着面積を縮小する。したがって粘着面積が縮小する分、剥離力を低減できるので、取り外し作業を容易化することが可能とされる。 In the handling method of the present invention having the above-described configuration, a step of peeling the carrier film from the gasket body against the adhesive force in a state where the gasket body is fixed to the base is performed, and a predetermined process is performed as a pre-process (pre-process). The adhesion area of the gasket body and carrier film is reduced according to the procedure. Therefore, since the peeling force can be reduced as much as the adhesive area is reduced, the removal operation can be facilitated.
　尚、キャリアフィルムがガスケット本体と平面上重なる部位に、ガスケット本体の外形形状に沿って変形した立体形状のガスケット保持部を備えている場合には、ガスケット保持部の内側にガスケット本体の一部または全部が収められた状態でキャリアフィルムおよびガスケット本体が粘着しているので、粘着面積の大きさがガスケット保持部の内面の面積によって規定される。したがってこの場合には前工程として、このガスケット保持部の内面の面積によって規定される粘着面積を縮小することになる。 In addition, when the carrier film has a three-dimensional gasket holding part deformed along the outer shape of the gasket main body in a portion where the gasket main body is overlapped on a plane, a part of the gasket main body or the inside of the gasket holding part is provided. Since the carrier film and the gasket main body are adhered in a state in which all are accommodated, the size of the adhesion area is defined by the area of the inner surface of the gasket holding portion. Therefore, in this case, as a pre-process, the adhesive area defined by the area of the inner surface of the gasket holding portion is reduced.
　剥離工程の前工程で用いるプレス装置としては、キャリアフィルム側からガスケット本体を押圧する押圧用突起部を有するものが好適であり、特に押圧用突起部の幅寸法をガスケット本体の幅寸法よりも小さく設定すると、剥離が押圧用突起部の両側まで及ぶので、剥離面積が拡大し、これに伴って粘着面積を一層縮小することが可能とされる。 As the pressing device used in the pre-process of the peeling process, a device having a pressing projection for pressing the gasket body from the carrier film side is suitable, and the width dimension of the pressing projection is particularly smaller than the width dimension of the gasket body. When set, the peeling extends to both sides of the pressing protrusion, so that the peeling area is increased, and the adhesive area can be further reduced accordingly.
　また、この押圧用突起部については、ガスケット本体の長手方向に沿って複数の突起を間隔をあけて並んで配置することも考えられ、この場合、互いに隣り合う突起間の空所はガスケット本体を押圧しない非押圧部とされ、この非押圧部ではキャリアフィルムがガスケット本体から剥離した状態とされる。したがってこの態様によっても剥離面積が拡大し、これに伴って粘着面積を一層縮小することが可能とされる。 In addition, with respect to the pressing protrusion, a plurality of protrusions may be arranged side by side along the longitudinal direction of the gasket body. In this case, the space between the protrusions adjacent to each other may be The non-pressing portion is a non-pressing portion, and the carrier film is peeled off from the gasket body at the non-pressing portion. Therefore, the peeled area is increased also by this aspect, and the adhesive area can be further reduced accordingly.
　上記前工程および剥離工程は、連続または同時に実施するのが効率的であり、このためベースに、ベース本体と、ベース本体に対し相対移動するスライド部と、スライド部に設けられたガスケット本体保持部と、ガスケット本体保持部に開口するように設けられた吸引用流路とを設定する。 It is efficient to carry out the above pre-process and the peeling process continuously or simultaneously. For this reason, a base body, a slide part that moves relative to the base body, and a gasket body holding part provided in the slide part And a suction channel provided so as to open to the gasket body holding portion.
　本発明によれば、ラバーオンリータイプのガスケット本体およびガスケット本体を保持する樹脂製のキャリアフィルムの組み合わせよりなるキャリアフィルム付きガスケットにおいてガスケット本体からキャリアフィルムを取り外す際に、ガスケット本体がキャリアフィルムに粘着していてもキャリアフィルムを容易に取り外すことが可能とされる。したがってキャリアフィルム取り外し作業を容易化し、キャリアフィルム付きガスケットの取り扱い性を向上させることができる。 According to the present invention, when removing a carrier film from a gasket body in a gasket with a carrier film comprising a rubber-only type gasket body and a resin carrier film holding the gasket body, the gasket body adheres to the carrier film. The carrier film can be easily removed. Therefore, the carrier film removing operation can be facilitated, and the handleability of the gasket with the carrier film can be improved.

　つぎに本発明の実施例を図面にしたがって説明する。 Next, embodiments of the present invention will be described with reference to the drawings.
　当該実施例に係るキャリアフィルム付きガスケットの取り扱い方法は、図１に示すキャリアフィルム付きガスケット２１を取り扱うものであって、すなわちラバーオンリータイプのガスケット本体３１およびこのガスケット本体３１を保持する樹脂製のキャリアフィルム４１の組み合わせよりなるキャリアフィルム付きガスケット２１においてガスケット本体３１からキャリアフィルム４１を取り外す方法である。ガスケット本体３１およびキャリアフィルム４１は互いに非接着とされているが、ガスケット本体３１の材質上の特性などによってガスケット本体３１がキャリアフィルム４１に対し粘着することがある。ガスケット本体３１は例えば燃料電池用ガスケットとして用いられる。 The method for handling a gasket with a carrier film according to this embodiment is to handle the gasket with a carrier film 21 shown in FIG. 1, that is, a rubber-only type gasket main body 31 and a resin carrier that holds the gasket main body 31. This is a method of removing the carrier film 41 from the gasket main body 31 in the gasket 21 with a carrier film made of a combination of the films 41. Although the gasket body 31 and the carrier film 41 are not bonded to each other, the gasket body 31 may stick to the carrier film 41 due to the material characteristics of the gasket body 31 and the like. The gasket body 31 is used, for example, as a fuel cell gasket.
　ガスケット本体３１は、所定のゴム状弾性体（例えばＶＭＱ、ＰＩＢ、ＥＰＤＭ、ＦＫＭなど）によって全体として平面状（平板状）に成形され、燃料電池の反応面の周りを全周に亙ってシールする外周シール部３２が平面長方形の枠状に設けられている。また、燃料電池の反応面と各マニホールド部を仕切るため、外周シール部３２の長手方向両端部にそれぞれ内側シール部（マニホールドシール部）３３が一体に設けられている。符号３４は、ガスケット本体３１をその厚み方向に貫通する貫通穴部（空間部）を示している。ガスケット本体３１の断面形状は図１（Ｂ）に示すように断面長方形とされ、その上面部に断面三角形のシールリップ３５が一体成形されている。 The gasket body 31 is formed in a flat shape (flat plate shape) as a whole by a predetermined rubber-like elastic body (for example, VMQ, PIB, EPDM, FKM, etc.), and seals around the reaction surface of the fuel cell over the entire circumference. An outer peripheral seal portion 32 is provided in a planar rectangular frame shape. Further, in order to partition the reaction surface of the fuel cell and each manifold portion, inner seal portions (manifold seal portions) 33 are integrally provided at both ends in the longitudinal direction of the outer peripheral seal portion 32. Reference numeral 34 denotes a through hole portion (space portion) that penetrates the gasket body 31 in the thickness direction. As shown in FIG. 1B, the cross section of the gasket body 31 has a rectangular cross section, and a seal lip 35 having a triangular cross section is integrally formed on the top surface thereof.
　キャリアフィルム４１は、ガスケット本体３１よりも一回りほど大きな平面長方形とされた樹脂フィルムよりなり、その平面上一部であってガスケット本体３１と平面上重なる部位に、ガスケット本体３１を保持するための立体形状よりなるガスケット保持部４２が設けられている。樹脂フィルムとしては例えば、厚さ０．２ｍｍのポリプロピレンフィルムを使用し、これを所定の平面形状に裁断して使用する。樹脂フィルムとしてはポリプロピレンの他に、ポリエチレン、ポリスチレンなど一般樹脂材が使用可能である。フィルムの厚さについては、ガスケット本体３１の線径や断面形状にもよるが、０．１ｍｍ～０．３ｍｍ程度とするのが好ましい。キャリアフィルム４１は、キャリアシートまたはガスケット保持部材とも称する。 The carrier film 41 is made of a resin film having a flat rectangular shape that is slightly larger than the gasket main body 31, and is used to hold the gasket main body 31 in a part of the plane that overlaps the gasket main body 31. A gasket holding portion 42 having a three-dimensional shape is provided. As the resin film, for example, a polypropylene film having a thickness of 0.2 mm is used, which is cut into a predetermined planar shape. In addition to polypropylene, general resin materials such as polyethylene and polystyrene can be used as the resin film. The thickness of the film is preferably about 0.1 mm to 0.3 mm, although it depends on the wire diameter and cross-sectional shape of the gasket body 31. The carrier film 41 is also referred to as a carrier sheet or a gasket holding member.
　上記キャリアフィルム付きガスケット２１はこれを、以下のようにして製造する。製造に際しては、ラバーオンリータイプのガスケット本体３１を射出成形する金型（ゴム成形型）を用いることができる。 The above-mentioned gasket 21 with a carrier film is manufactured as follows. In manufacturing, a mold (rubber mold) for injection molding the rubber-only type gasket main body 31 can be used.
　工程としては先ず、所定の大きさの平面形状に裁断した平面状のキャリアフィルム４１を用意し、図２（Ａ）に示すように、このキャリアフィルム４１を金型５１のパーティング部５４に挟み込んだ状態で金型５１を型締めする。金型５１は上型（一方の分割型）５２および下型（他方の分割型）５３の組み合わせよりなり、両型５２，５３のパーティング部５４にそれぞれキャビティ部５５が一部ずつ対応して設けられている。キャリアフィルム４１は当初その全面が平面状であるため、キャビティ部５５内を横切る状態とされる。 As a process, first, a planar carrier film 41 cut into a planar shape of a predetermined size is prepared, and the carrier film 41 is sandwiched between parting portions 54 of a mold 51 as shown in FIG. In this state, the mold 51 is clamped. The mold 51 is composed of a combination of an upper mold (one split mold) 52 and a lower mold (the other split mold) 53, and the cavity portions 55 respectively correspond to the parting portions 54 of both molds 52 and 53. Is provided. Since the entire surface of the carrier film 41 is initially flat, the carrier film 41 is in a state of crossing the cavity portion 55.
　次いで、図２（Ｂ）に示すように、キャビティ部５５へガスケット本体３１を成形するための成形材料を充填し加熱する等して、ガスケット本体３１を成形する。キャビティ部５５へ成形材料を充填したとき、キャリアフィルム４１はその平面上一部が成形材料充填圧力によって下型５３のキャビティ部５５の内面に押し付けられ、キャビティ部５５の内面に沿ったかたちに変形（塑性変形）し、これにより立体形状よりなるガスケット保持部４２が成形される。 Next, as shown in FIG. 2 (B), the gasket body 31 is molded by filling the cavity portion 55 with a molding material for molding the gasket body 31 and heating. When the cavity material 55 is filled with the molding material, the carrier film 41 is partially pressed on the inner surface of the cavity portion 55 of the lower mold 53 by the molding material filling pressure, and deformed along the inner surface of the cavity portion 55. (Plastic deformation), thereby forming a gasket holding portion 42 having a three-dimensional shape.
　次いで、図２（Ｃ）に示すように、ガスケット本体３１の成形後、型開きし、図２（Ｄ）に示すように、ガスケット本体３１およびキャリアフィルム４１を同時に金型５１から取り出す。取り出したガスケット本体３１およびキャリアフィルム４１は、ガスケット本体３１がキャリアフィルム４１によって保持された組み合わせ状態とされ、この組み合わせ状態で製品の搬送や保管などを行う。キャリアフィルム４１によって保持されたガスケット本体３１には捩れ等が生じにくく、よってガスケット本体３１を単品で取り扱う場合よりも取扱い作業性を向上させることができる。 Next, as shown in FIG. 2C, after the gasket body 31 is molded, the mold is opened, and the gasket body 31 and the carrier film 41 are simultaneously taken out from the mold 51 as shown in FIG. The taken-out gasket main body 31 and carrier film 41 are in a combined state in which the gasket main body 31 is held by the carrier film 41, and products are transported and stored in this combined state. The gasket main body 31 held by the carrier film 41 is less likely to be twisted, so that the handling workability can be improved as compared with the case where the gasket main body 31 is handled alone.
　ガスケット本体３１およびキャリアフィルム４１は互いに非接着とされるが、ガスケット本体３１の材質上の特性や金型５１による成形上の都合などによってガスケット本体３１がその表面に粘着性を備え、この粘着性によってガスケット本体３１がキャリアフィルム４１に対し粘着してしまうことがある。そこで当該実施例では、以下の手順にてガスケット本体３１からキャリアフィルム４１を取り外す作業を行う。 The gasket main body 31 and the carrier film 41 are not bonded to each other, but the gasket main body 31 has adhesiveness on the surface due to the characteristics of the material of the gasket main body 31 and the convenience of molding by the mold 51. As a result, the gasket main body 31 may stick to the carrier film 41. Therefore, in this embodiment, the operation of removing the carrier film 41 from the gasket body 31 is performed according to the following procedure.
　すなわち先ず、前工程（前処理工程）として図３（Ａ）（Ｂ）に示すように、キャリアフィルム付きガスケット２１をプレス装置７１にセットし、このプレス装置７１を用いてキャリアフィルム４１側からガスケット本体３１を押圧し、これによりガスケット本体３１およびキャリアフィルム４１の粘着面積を縮小する。 That is, first, as shown in FIGS. 3A and 3B as a pre-process (pre-process), a gasket 21 with a carrier film is set in a press device 71, and the gasket is used from the carrier film 41 side using this press device 71. The main body 31 is pressed, and thereby the adhesion area of the gasket main body 31 and the carrier film 41 is reduced.
　すなわちキャリアフィルム４１は上記したように、そのガスケット本体３１と平面上重なる部位に、ガスケット本体３１の外形形状に沿って変形した立体形状よりなるガスケット保持部４２を備え、この立体形状よりなるガスケット保持部４２の内側にガスケット本体３１の一部または全部が収められた状態でキャリアフィルム４１およびガスケット本体３１が粘着しているので、キャリアフィルム４１およびガスケット本体３１の粘着面積はガスケット保持部４２の内面の面積によって規定される。 That is, as described above, the carrier film 41 includes the gasket holding portion 42 having a three-dimensional shape deformed along the outer shape of the gasket main body 31 at a portion overlapping the gasket main body 31 on a plane, and holding the gasket having the three-dimensional shape. Since the carrier film 41 and the gasket body 31 are adhered in a state where a part or all of the gasket body 31 is accommodated inside the portion 42, the adhesion area of the carrier film 41 and the gasket body 31 is the inner surface of the gasket holding portion 42. Is defined by the area.
　その内訳としては、ガスケット本体３１が断面長方形とされているので、ガスケット本体３１の底面に粘着するガスケット保持部４２の底面部４２ａの面積、ガスケット本体３１の一方の側面の一部に粘着するガスケット保持部４２の一方の側面部４２ｂの面積、およびガスケット本体３１の他方の側面の一部に粘着するガスケット保持部４２の他方の側面部４２ｃの面積の和と云うことになり、これら面積の和よりなる粘着面積を縮小し、このため上記したようにプレス装置７１を用いてキャリアフィルム４１側からガスケット本体３１を押圧すると図３（Ｂ）に示すように、ガスケット保持部４２の一方の側面部４２ｂがガスケット本体３１の一方の側面から剥がれ、ガスケット保持部４２の他方の側面部４２ｃがガスケット本体３１の他方の側面から剥がれ、ガスケット保持部４２の底面部４２ａがその一部（幅方向両端部）でガスケット本体３１の底面から剥がれ、結果として、残る粘着部はガスケット保持部４２の底面部４２ａの一部（幅方向中央の一部）のみとなり、これにて前工程を完了する。 The breakdown is that the gasket body 31 has a rectangular cross section, and therefore the area of the bottom surface portion 42 a of the gasket holding portion 42 that adheres to the bottom surface of the gasket body 31 and the gasket that adheres to a part of one side surface of the gasket body 31. This is the sum of the area of one side surface portion 42b of the holding portion 42 and the area of the other side surface portion 42c of the gasket holding portion 42 that adheres to a part of the other side surface of the gasket body 31. When the gasket main body 31 is pressed from the carrier film 41 side using the press device 71 as described above, as shown in FIG. 3B, one side surface portion of the gasket holding portion 42 is reduced. 42 b is peeled off from one side surface of the gasket body 31, and the other side surface portion 42 c of the gasket holding portion 42 is removed from the gasket body 31. The bottom surface portion 42a of the gasket holding portion 42 is peeled off from the bottom surface of the gasket main body 31 at a part (both ends in the width direction), and as a result, the remaining adhesive portion is a part of the bottom surface portion 42a of the gasket holding portion 42. This is the only part (part of the center in the width direction), and this completes the previous process.
　この前工程を実施するため、プレス装置７１の押圧側構成要素７１Ａには、キャリアフィルム４１側（ガスケット保持部４２の底面部４２ａ側）からガスケット本体３１を押圧するための押圧用突起部７２が設けられ、対応してプレス装置７１の被押圧側構成要素７１Ｂには、押圧により変位したガスケット本体３１を一時的に収めるための受け空間部７３が設けられている。 In order to perform this pre-process, a pressing protrusion 72 for pressing the gasket main body 31 from the carrier film 41 side (the bottom surface portion 42a side of the gasket holding portion 42) is provided on the pressing side component 71A of the pressing device 71. Correspondingly, the pressed side component 71B of the pressing device 71 is provided with a receiving space 73 for temporarily storing the gasket body 31 displaced by pressing.
　押圧用突起部７２としては図４（Ａ）（Ｂ）に示すように、その幅寸法ｗ１をガスケット本体３１の幅寸法ｗ２以上の大きさとしても良いが、図５（Ａ）（Ｂ）に示すように、その幅寸法ｗ１をガスケット本体３１の幅寸法ｗ２よりも小さく設定しても良く、この後者の場合には、押圧用突起部７２がガスケット本体３１の底面の一部（幅方向中央の一部）のみを押圧するため、上記したようにガスケット保持部４２の一方の側面部４２ｂがガスケット本体３１から剥がれ、ガスケット保持部４２の他方の側面部４２ｃがガスケット本体３１から剥がれ、ガスケット保持部４２の底面部４２ａもその一部（幅方向両端部）がガスケット本体３１から剥がれることになる。したがって、残る粘着部はガスケット保持部４２の底面部４２ａの一部（幅方向中央の一部）のみとなり、よって粘着面積を随分と縮小することができる。 As shown in FIGS. 4A and 4B, the pressing protrusion 72 may have a width dimension w 1 that is greater than or equal to the width dimension w 2 of the gasket body 31, but FIGS. ), The width dimension w 1 may be set smaller than the width dimension w 2 of the gasket body 31, and in this latter case, the pressing projection 72 is a part of the bottom surface of the gasket body 31. In order to press only (a part in the center in the width direction), as described above, one side surface portion 42b of the gasket holding portion 42 is peeled off from the gasket body 31, and the other side surface portion 42c of the gasket holding portion 42 is separated from the gasket body 31. As a result, the bottom surface portion 42 a of the gasket holding portion 42 is partly peeled off from the gasket body 31 (both ends in the width direction). Therefore, the remaining adhesive part is only a part of the bottom face part 42a (part of the center in the width direction) of the gasket holding part 42, and thus the adhesive area can be considerably reduced.
　次いで、上記前工程に引きつづき図６（Ａ）（Ｂ）に示すように、キャリアフィルム付きガスケット２１をベースとしての真空引き装置６１の吸着部６２にセットし、真空引き（矢印Ｓ）を行ってガスケット本体３１を固定（吸着）させつつ、この状態でチャック装置（図示せず）などを用いてガスケット本体３１からキャリアフィルム４１を剥離させる。このときキャリアフィルム４１およびガスケット本体３１の粘着面積は上記前工程ですでに縮小しているため、比較的小さな剥離力および短い剥離処理時間をもってキャリアフィルム４１をガスケット本体３１から取り外すことができる。したがって本発明所期の目的どおり、ガスケット本体３１がキャリアフィルム４１に粘着していてもキャリアフィルム４１を容易に取り外すことが可能とされ、キャリアフィルム４１の取り外し作業を容易化することができる。 Subsequently, as shown in FIGS. 6 (A) and 6 (B), following the preceding process, the gasket 21 with a carrier film is set on the suction part 62 of the vacuuming device 61 as a base, and vacuuming (arrow S) is performed. The carrier film 41 is peeled from the gasket body 31 using a chuck device (not shown) or the like in this state while fixing (adsorbing) the gasket body 31. At this time, since the adhesive areas of the carrier film 41 and the gasket body 31 have already been reduced in the previous step, the carrier film 41 can be removed from the gasket body 31 with a relatively small peeling force and a short peeling treatment time. Therefore, as the intended purpose of the present invention, even if the gasket main body 31 is adhered to the carrier film 41, the carrier film 41 can be easily removed, and the removal work of the carrier film 41 can be facilitated.
　尚、ラバーオンリータイプのガスケット本体３１および樹脂製のキャリアフィルム４１の組み合わせよりなるキャリアフィルム付きガスケット２１の断面形状としては様々なものが考えられ、上記図１（Ｂ）に示すものに限定されない。 In addition, various things can be considered as the cross-sectional shape of the gasket 21 with a carrier film which consists of the combination of the rubber-only type gasket main body 31 and the resin carrier film 41, and it is not limited to what is shown to the said FIG. 1 (B).
　例えば、図７（Ａ）に示す例では、断面長方形のガスケット本体３１の上面部ではなく底面部にシールリップ３５が一体成形されており、これに伴ってキャリアフィルム４１における立体形状よりなるガスケット保持部４２の形状も変更されている。 For example, in the example shown in FIG. 7A, the seal lip 35 is integrally formed on the bottom surface instead of the top surface of the gasket body 31 having a rectangular cross section. The shape of the part 42 is also changed.
　また、本発明には図７（Ｂ）に示すように、キャリアフィルム４１が立体形状よりなるガスケット保持部４２を備えず平面形状のままで用いられる場合も含まれる。この場合、キャリアフィルム４１およびガスケット本体３１の粘着面積はガスケット本体３１の底面の面積をもって規定されるので、上記した前工程を実施すると、このガスケット本体３１の底面の面積をもって規定される粘着面積が縮小し、具体的には、ガスケット本体３１の底面の幅方向両端部においてそれぞれキャリアフィルム４１が剥がれることになる。 In addition, as shown in FIG. 7B, the present invention includes a case in which the carrier film 41 is used without being provided with a three-dimensional gasket holding portion 42 in a planar shape. In this case, the adhesion area of the carrier film 41 and the gasket body 31 is defined by the area of the bottom surface of the gasket body 31. Therefore, when the above-described pre-process is performed, the adhesion area defined by the area of the bottom surface of the gasket body 31 is More specifically, the carrier film 41 is peeled off at both ends of the bottom surface of the gasket body 31 in the width direction.
　更にまた、上記前工程の実施による粘着面積の縮小については、プレス装置７１の押圧側構成要素７１Ａに設ける押圧用突起部７２を以下のように構成することも考えられる。 Furthermore, with respect to the reduction of the adhesion area due to the implementation of the preceding step, it is also conceivable that the pressing protrusion 72 provided on the pressing side component 71A of the pressing device 71 is configured as follows.
　すなわち上記実施例では、押圧用突起部７２はガスケット本体３１の長手方向全長に亙って設けられ、ガスケット本体３１をその長手方向全長に亙って押圧するものとされているが、この押圧用突起部７２をガスケット本体３１の長手方向に沿って複数の突起が間隔をあけて並んで配置されたものとし、互いに隣り合う突起間の空所をガスケット本体３１を押圧しない非押圧部とする。 That is, in the above embodiment, the pressing projection 72 is provided over the entire length in the longitudinal direction of the gasket body 31 and presses the gasket body 31 over the entire length in the longitudinal direction. A plurality of protrusions are arranged at intervals along the longitudinal direction of the gasket body 31 in the protrusion 72, and a space between adjacent protrusions is a non-pressing portion that does not press the gasket body 31.
　図８は、この場合における複数の突起の配置状況の一例を示し、図８における斜線部分が突起が配置される部位７４を示すとともに、図８における白抜き部分が突起が配置されずに非押圧部とされる部位７５を示し、図示するように両部位７４，７５がガスケット本体３１の長手方向に沿って交互に並んで配置されている。 FIG. 8 shows an example of the arrangement state of a plurality of protrusions in this case. The hatched portion in FIG. 8 indicates a portion 74 where the protrusion is disposed, and the white portion in FIG. 8 is not pressed without the protrusion being disposed. The part 75 used as a part is shown and both the parts 74 and 75 are arrange | positioned along with the longitudinal direction of the gasket main body 31 alternately so that it may show in figure.
　そして、このような構成によれば、突起が配置される部位７４では図４および図５に示したように、押圧用突起部７２がキャリアフィルム４１を介してガスケット本体３１を押圧するため、押圧される部位はこの部位のみキャリアフィルム４１とガスケット本体３１が粘着している部分として残る。一方、突起が配置されずに非押圧部とされる部位７５では図９（Ａ）（Ｂ）に示すように突起がないため、キャリアフィルム４１とガスケット本体３１が粘着しておらず剥離している部分とされる。したがって前処理後に残る粘着面積を随分と縮小することができる。 According to such a configuration, the pressing protrusion 72 presses the gasket body 31 via the carrier film 41 at the portion 74 where the protrusion is disposed, as shown in FIGS. The part to be left remains as a part where the carrier film 41 and the gasket body 31 are adhered only to this part. On the other hand, as shown in FIGS. 9 (A) and 9 (B), there is no protrusion in the portion 75 where the protrusion is not disposed and the non-pressing portion, and the carrier film 41 and the gasket body 31 are not adhered and peeled off. It is supposed to be a part. Therefore, the adhesion area remaining after the pretreatment can be considerably reduced.

　ガスケット本体３１およびキャリアフィルム４１間の粘着面積を縮小する上記の前工程と、ガスケット本体３１からキャリアフィルム４１を取り外す上記の剥離工程とは、連続または同時に実施することにより、作業効率を向上させることができる。以下、この場合の実施例について説明する。 Other embodiments ...
The above-mentioned pre-process for reducing the adhesion area between the gasket body 31 and the carrier film 41 and the above-described peeling process for removing the carrier film 41 from the gasket body 31 are performed continuously or simultaneously to improve work efficiency. Can do. Hereinafter, an embodiment in this case will be described.
　すなわち図１０（Ａ）に示すように、ベース８１に静止側のベース本体８２が設けられるとともにこのベース本体８２に凹部（シリンダ状凹部）８３がプレス装置７１の押圧用突起部７２と対向するように設けられている。凹部８３に可動側のスライド部（ピストン状スライド部材）８４がスライド可能に組み付けられ、凹部８３の底部にスライド部８４をスライド初動位置に復帰動させる復帰バネ８５が設けられている。 That is, as shown in FIG. 10A, a base body 82 on the stationary side is provided on the base 81, and a recess (cylinder-shaped recess) 83 is opposed to the pressing projection 72 of the press device 71. Is provided. A movable slide portion (piston-like slide member) 84 is slidably assembled to the recess 83, and a return spring 85 is provided at the bottom of the recess 83 to return the slide portion 84 to the initial slide position.
　スライド部８４に、ガスケット本体３１をこのスライド部８４に保持するためのガスケット本体保持部８６が開口部として設けられ、また、ガスケット本体３１をこのガスケット本体保持部８６に吸引固定するための吸引用流路８７が上記開口部へ通じるように設けられている。吸引用流路８７は配管８８を介して、図示しない真空引きポンプ等の吸引源に接続されている。 The slide portion 84 is provided with a gasket main body holding portion 86 for holding the gasket main body 31 on the slide portion 84 as an opening, and for suction for fixing the gasket main body 31 to the gasket main body holding portion 86 by suction. A flow path 87 is provided to communicate with the opening. The suction channel 87 is connected to a suction source such as a vacuum pump (not shown) via a pipe 88.
　図１０（Ａ）に示すように、前工程を開始するに際し、ガスケット本体３１がスライド部８４のガスケット本体保持部８６に位置するようにキャリアフィルム付きガスケット２１をベース８１に対しセットする。 As shown in FIG. 10A, when starting the pre-process, the carrier film-equipped gasket 21 is set on the base 81 so that the gasket main body 31 is positioned at the gasket main body holding portion 86 of the slide portion 84.
　次いで、吸引源を駆動し真空引き（矢印Ｓ）を開始して、ガスケット本体３１をスライド部８４のガスケット本体保持部８６に吸引固定し、この吸引固定した状態で図１０（Ｂ）に示すように、プレス装置７１の押圧用突起部７２でキャリアフィルム４１側からガスケット本体３１を押圧し、これによりガスケット本体３１およびキャリアフィルム４１間の粘着面積を縮小させる。プレス装置７１の押圧用突起部７２でキャリアフィルム４１側からガスケット本体３１を押圧するとスライド部８４も押圧され、スライド部８４が復帰バネ８５の弾性に抗してスライド移動する。 Next, the suction source is driven to start evacuation (arrow S), and the gasket main body 31 is sucked and fixed to the gasket main body holding portion 86 of the slide portion 84, and this suction fixed state is shown in FIG. 10B. Then, the gasket main body 31 is pressed from the carrier film 41 side by the pressing projection 72 of the pressing device 71, thereby reducing the adhesion area between the gasket main body 31 and the carrier film 41. When the gasket main body 31 is pressed from the carrier film 41 side by the pressing protrusion 72 of the pressing device 71, the slide portion 84 is also pressed, and the slide portion 84 slides against the elasticity of the return spring 85.
　次いで、図１１（Ａ）に示すようにキャリアフィルム４１をプレス装置７１側へ固定し、この固定した状態でプレス装置７１を復帰動（後退動）させると、ガスケット本体３１はベース８１側に吸引固定されたままであるので、ガスケット本体３１からキャリアフィルム４１が取り外される。 Next, as shown in FIG. 11A, the carrier film 41 is fixed to the press device 71 side, and when the press device 71 is returned (retracted) in this fixed state, the gasket body 31 is sucked to the base 81 side. Since it remains fixed, the carrier film 41 is removed from the gasket body 31.
　次いで、図１１（Ｂ）に示すようにベース８１側に吸引固定された状態のガスケット本体３１を燃料電池セパレータ等の取付けの相手部品９１と向き合わせ、必要に応じてガスケット本体３１に接着剤を塗布したうえで、図１２（Ａ）に示すようにガスケット本体３１を相手部品９１に取り付け、図１２（Ｂ）に示すように取付け工程を完了する。 Next, as shown in FIG. 11 (B), the gasket main body 31 in a state of being sucked and fixed to the base 81 side is faced with a mating component 91 such as a fuel cell separator, and an adhesive is applied to the gasket main body 31 as necessary. After the application, the gasket body 31 is attached to the counterpart component 91 as shown in FIG. 12A, and the attachment process is completed as shown in FIG.
　したがって、上記構成のスライド構造を設けたベース８１を用いることにより、前工程および剥離工程を連続または同時に実施し、これにより作業効率を向上させることができる。 Therefore, by using the base 81 provided with the slide structure having the above-described configuration, the pre-process and the peeling process can be performed continuously or simultaneously, thereby improving work efficiency.
