Description

補強フィルム接着装置Reinforcing film bonding device
　本発明は、例えば、ファスナーチェーンの開離嵌挿具を取り付けるスペース部に、合成樹脂製の補強フィルムを取り付ける補強フィルム接着装置に関する。 The present invention relates to a reinforcing film bonding apparatus for attaching a synthetic resin reinforcing film to, for example, a space for attaching a fastener chain opening / closing insert.
　従来、ファスナーチェーンのスペース部に、熱可塑性合成樹脂よりなる補強テープ（補強フィルム片）をファスナーチェーンに接着するようにした補強テープ貼着方法が開示されている（例えば、特許文献１参照）。この補強テープ貼着方法は、グリッパが連続する補強帯条をファスナーチェーンの搬送方向と直交する方向から引き出す工程と、切断装置が補強帯条を切断して、短尺の補強帯を形成する工程と、グリッパがファスナーチェーンのスペース部に補強帯を配置する工程と、超音波ホーンとアンビルが補強帯の一部をスペース部に接着する工程と、加熱したダイプレートが補強帯の残部をスペース部に接着する工程とを備えている。 Conventionally, a reinforcing tape affixing method in which a reinforcing tape (reinforcing film piece) made of a thermoplastic synthetic resin is bonded to a fastener chain in a space portion of the fastener chain has been disclosed (for example, see Patent Document 1). This method of sticking the reinforcing tape includes a step of pulling out the reinforcing strip in which the gripper is continuous from a direction perpendicular to the conveying direction of the fastener chain, and a step of cutting the reinforcing strip by the cutting device to form a short reinforcing strip. The gripper places the reinforcing band in the space part of the fastener chain, the ultrasonic horn and the anvil bond part of the reinforcing band to the space part, and the heated die plate makes the remaining part of the reinforcing band into the space part. And a step of bonding.

　ファスナーチェーンに補強帯を接着する加熱手段としては、超音波接着装置や加熱ヒータなどがある。超音波接着装置は、補強帯を短時間で加熱することができる。しかるに、溶融した補強帯がファスナーテープの組織に浸透し難い。これにより、ファスナーチェーンと補強帯の接着強度が低くなる傾向がある。特に、ファスナーテープの表面に撥水処理層や、止水層が形成されたファスナーチェーンでは、この傾向が強い。このため、補強帯は、比較的長時間で加熱されることが必要である。しかし、補強帯は、長時間加熱されると、補強帯とファスナーチェーンの間に気泡が発生して、白濁が発生する問題があった。 There are an ultrasonic bonding device and a heater as a heating means for bonding the reinforcing band to the fastener chain. The ultrasonic bonding apparatus can heat the reinforcing band in a short time. However, it is difficult for the molten reinforcing band to penetrate into the structure of the fastener tape. Thereby, there exists a tendency for the adhesive strength of a fastener chain and a reinforcement belt to become low. In particular, this tendency is strong in a fastener chain in which a water repellent layer or a water stop layer is formed on the surface of the fastener tape. For this reason, the reinforcing band needs to be heated for a relatively long time. However, when the reinforcing band is heated for a long time, there is a problem that bubbles are generated between the reinforcing band and the fastener chain, thereby causing white turbidity.
　特許文献１に記載の補強テープ貼着方法は、加熱したダイプレートでファスナーチェーンを挟圧し、所定の時間加熱して、補強帯をファスナーチェーンに接着している。このため、補強帯は、ファスナーチェーンとの接着強度は高いものの、白濁が発生してしまい、外観上の見栄えが悪く、商品価値が低下してしまっていた。 In the reinforcing tape sticking method described in Patent Document 1, the fastener chain is clamped with a heated die plate and heated for a predetermined time to bond the reinforcing band to the fastener chain. For this reason, although the reinforcement band has high adhesive strength with the fastener chain, white turbidity is generated, the appearance is not good, and the commercial value is lowered.
　本発明は、前述した事情に鑑みてなされたものであり、その目的は、ファスナーチェーンと補強フィルム片との接着強度を確保すると共に、補強フィルム片に白濁が発生することを防止することができる補強フィルム接着装置を提供することにある。 This invention is made | formed in view of the situation mentioned above, The objective can ensure that the cloudiness generate | occur | produces in a reinforcement film piece while ensuring the adhesive strength of a fastener chain and a reinforcement film piece. The object is to provide a reinforcing film bonding apparatus.

　以下、本発明に係る補強フィルム接着装置の一実施形態について、図面に基づいて詳細に説明する。図１～図３に示すように、補強フィルム接着装置１０は、不図示の開離嵌挿具が取り付けられるファスナーチェーン１１のスペース部１２に、補強フィルム片１６を接着する接着装置である。この補強フィルム接着装置１０は、ファスナーチェーン搬送手段２０と、補強フィルムテープ供給手段３０と、切断機構４０と、補強フィルム片搬送手段５０と、補強フィルム片接着手段としての熱接着装置７０と、フィルム片冷却装置８０と、を備える。 Hereinafter, an embodiment of a reinforcing film bonding apparatus according to the present invention will be described in detail based on the drawings. As shown in FIGS. 1 to 3, the reinforcing film bonding apparatus 10 is an bonding apparatus that bonds a reinforcing film piece 16 to a space portion 12 of a fastener chain 11 to which an unillustrated opening / closing insert is attached. This reinforcing film bonding apparatus 10 includes a fastener chain conveying means 20, a reinforcing film tape supplying means 30, a cutting mechanism 40, a reinforcing film piece conveying means 50, a thermal bonding apparatus 70 as a reinforcing film piece bonding means, and a film. Piece cooling device 80.
　ファスナーチェーン１１は、図５に示すように、長尺の一対のファスナーテープ１３の対向するテープ側縁部１３ａに沿ってファスナーエレメント列１５を有する。ファスナーエレメント列１５は、ファスナーチェーン１１の長さ方向に隣り合う多数のエレメント１４を有する。エレメント１４は、樹脂製で、テープ側縁部１３ａに射出成形されている。そして、ファスナーチェーン１１には、ファスナーチェーン１１の長さ方向の所定の間隔ごとに、ファスナーエレメント列１５から所定数のエレメント１４が除去されたスペース部１２が形成されている。 The fastener chain 11 has the fastener element row | line | column 15 along the tape side edge part 13a which a pair of elongate fastener tape 13 opposes, as shown in FIG. The fastener element row 15 has a large number of elements 14 adjacent to each other in the length direction of the fastener chain 11. The element 14 is made of resin and is injection-molded on the tape side edge portion 13a. The fastener chain 11 is formed with a space portion 12 in which a predetermined number of elements 14 are removed from the fastener element row 15 at predetermined intervals in the length direction of the fastener chain 11.
　ファスナーチェーン搬送手段２０は、図２に示すように、熱接着装置７０及びフィルム片冷却装置８０の設置位置よりもファスナーチェーン１１の搬送方向下流側に配置されている。ファスナーチェーン搬送手段２０は、搬送経路に沿ってファスナーチェーン１１を搬送する。そして、ファスナーチェーン搬送手段２０は、ファスナーチェーン１１の搬送経路を挟んで対向して配置された駆動ローラ２１と従動ローラ２２とを備えている。駆動ローラ２１は、図示せぬモータに接続されている。従動ローラ２２は、ファスナーチェーン１１を駆動ローラ２１に向けて押圧している。即ち、駆動ローラ２１と従動ローラ２２とでファスナーチェーン１１を挟持している。駆動ローラ２１を回転駆動することで、従動ローラ２２を同期的に回転させるとともに、ファスナーチェーン１１を搬送方向下流側へ向けて搬送する。 2, the fastener chain transport means 20 is arranged on the downstream side in the transport direction of the fastener chain 11 from the installation position of the thermal bonding device 70 and the film piece cooling device 80. The fastener chain transport means 20 transports the fastener chain 11 along the transport path. The fastener chain conveying means 20 includes a driving roller 21 and a driven roller 22 that are arranged to face each other across the conveying path of the fastener chain 11. The drive roller 21 is connected to a motor (not shown). The driven roller 22 presses the fastener chain 11 toward the drive roller 21. That is, the fastener chain 11 is sandwiched between the driving roller 21 and the driven roller 22. By driving the drive roller 21 to rotate, the driven roller 22 is synchronously rotated and the fastener chain 11 is transported downstream in the transport direction.
　感知手段２４は、熱接着装置７０の設置位置よりファスナーチェーン１１の搬送方向上流側に配置されている。感知手段２４は、ファスナーエレメント列１５の上方に配置された感知ローラ２５と、感知ローラ２５を上下方向に揺動可能に支持する揺動レバー２６を有する。感知ローラ２５は、搬送されるファスナーチェーン１１のファスナーエレメント列１５に接触しながら回転する。感知ローラ２５は、搬送されるファスナーチェーン１１のスペース部１２が感知ローラ２５の下方位置に達した時、スペース部１２に侵入する。この時、感知ローラ２５は、一対のファスナーテープのテープ側縁部１３ａ間に形成された隙間Ｓに入り込む。これにより、感知手段２４は、感知ローラ２５が下方へ移動するとともに、揺動レバー２６が下方へ揺動して、スペース部１２を検出する。 The sensing means 24 is arranged on the upstream side in the conveying direction of the fastener chain 11 from the installation position of the thermal bonding apparatus 70. The sensing means 24 includes a sensing roller 25 disposed above the fastener element row 15 and a swing lever 26 that supports the sense roller 25 so as to be swingable in the vertical direction. The sensing roller 25 rotates while contacting the fastener element row 15 of the fastener chain 11 being conveyed. The sensing roller 25 enters the space portion 12 when the space portion 12 of the fastener chain 11 being conveyed reaches a position below the sensing roller 25. At this time, the sensing roller 25 enters the gap S formed between the tape side edges 13a of the pair of fastener tapes. As a result, the sensing means 24 detects the space portion 12 as the sensing roller 25 moves downward and the swing lever 26 swings downward.
　ファスナーチェーン搬送手段２０は、感知手段２４によりスペース部１２が検出されると、所定の距離だけファスナーチェーン１１をさらに搬送する。そして、ファスナーチェーン搬送手段２０は、スペース部１２が熱接着装置７０の位置と上面視で重なる位置に移動した時、ファスナーチェーン１１の搬送を停止する。そして、ファスナーチェーン搬送手段２０は、後述する熱接着装置７０が補強フィルム片１６の接着を完了した後、ファスナーチェーン１１の搬送を再開する。そして、ファスナーチェーン搬送手段２０は、スペース部１２、換言すれば、接着された補強フィルム片１６がフィルム片冷却装置８０の位置と上面視で重なる位置に移動した時、ファスナーチェーン１１の搬送を停止する。そして、ファスナーチェーン搬送手段２０は、フィルム片冷却装置８０が補強フィルム片１６を冷却した後、ファスナーチェーン１１の搬送を再開する。ファスナーチェーン搬送手段２０は、上記動作を繰り返して、ファスナーチェーン１１を搬送する。 The fastener chain conveying means 20 further conveys the fastener chain 11 by a predetermined distance when the space part 12 is detected by the sensing means 24. And the fastener chain conveyance means 20 stops conveyance of the fastener chain 11 when the space part 12 moves to the position which overlaps with the position of the heat bonding apparatus 70 in top view. And the fastener chain conveyance means 20 restarts conveyance of the fastener chain 11 after the thermobonding apparatus 70 mentioned later completes adhesion | attachment of the reinforcement film piece 16. FIG. The fastener chain transport means 20 stops the transport of the fastener chain 11 when the space portion 12, in other words, the adhered reinforcing film piece 16 moves to a position overlapping the position of the film piece cooling device 80 in a top view. To do. And the fastener chain conveyance means 20 restarts conveyance of the fastener chain 11 after the film piece cooling device 80 cools the reinforcement film piece 16. The fastener chain transport means 20 transports the fastener chain 11 by repeating the above operation.
　図２及び図３に示すように、補強フィルムテープ供給手段３０は、ファスナーチェーン１１の搬送経路の側方に配置されている。補強フィルムテープ供給手段３０は、補強フィルムテープ１７が巻回される不図示の補強フィルムテープロールを有する。そして、補強フィルムテープ供給手段３０は、補強フィルムテープ１７がファスナーチェーン１１の搬送方向と直交する方向に沿って延びるように、補強フィルムテープ１７を収容している。 2 and 3, the reinforcing film tape supply means 30 is disposed on the side of the conveying path of the fastener chain 11. The reinforcing film tape supply means 30 has a reinforcing film tape roll (not shown) around which the reinforcing film tape 17 is wound. The reinforcing film tape supply means 30 accommodates the reinforcing film tape 17 so that the reinforcing film tape 17 extends along a direction orthogonal to the conveying direction of the fastener chain 11.
　補強フィルムテープ供給手段３０は、ファスナーチェーン１１と対向する先端部に、ファスナーチェーン１１の搬送方向と直交する方向に移動可能なガイドヘッド３２を備える。即ち、ガイドヘッド３２は、ファスナーチェーン１１に対して接近する位置と離間する位置とに移動可能である。ガイドヘッド３２は、不図示のばねにより、ファスナーチェーン１１に接近する方向に付勢されている。ガイドヘッド３２は、補強フィルムテープ１７を挿通する一対のスリット３１を有する。各スリット３１は、上下方向に間隔を空けて、互いに平行に配置されている。補強フィルムテープ１７は、後述するグリッパ５１によって、各スリット３１から引き出される。この時、各スリット３１は、補強フィルムテープ１７がファスナーチェーン１１の上面及び下面に向けて引き出されるように、補強フィルムテープ１７の移動を案内する。 The reinforcing film tape supply means 30 includes a guide head 32 that is movable in a direction orthogonal to the conveying direction of the fastener chain 11 at a tip portion facing the fastener chain 11. That is, the guide head 32 is movable between a position approaching the fastener chain 11 and a position separating it. The guide head 32 is biased in a direction approaching the fastener chain 11 by a spring (not shown). The guide head 32 has a pair of slits 31 through which the reinforcing film tape 17 is inserted. The slits 31 are arranged in parallel to each other with an interval in the vertical direction. The reinforcing film tape 17 is pulled out from each slit 31 by a gripper 51 described later. At this time, each slit 31 guides the movement of the reinforcing film tape 17 so that the reinforcing film tape 17 is pulled out toward the upper surface and the lower surface of the fastener chain 11.
　なお、補強フィルムテープ１７は、ナイロン系やポリエステル系などの比較的低融点の合成樹脂で形成されたフィルムテープである。 The reinforcing film tape 17 is a film tape formed of a relatively low melting point synthetic resin such as nylon or polyester.
　切断機構４０は、図３に示すように、ガイドヘッド３２の下方に配置されたカッタ４１と、カッタ４１を上下方向に移動させるための駆動装置４２とを備える。即ち、カッタ４１は、ガイドヘッド３２に接近する上方位置と、ガイドヘッド３２から離間する下方位置とに移動可能である。この時、カッタ４１は、ガイドヘッド３２の先端面３２ａに沿って移動する。切断機構４０は、カッタ４１を上下動することで、一対のスリット３１から引き出された一対の補強フィルムテープ１７を切断して、一対の補強フィルム片１６を形成する。この補強フィルム片１６の長さ（ファスナーチェーン１１の搬送方向と直交する方向の長さ）は、ファスナーチェーン１１の幅より僅かに短くなるように設定されている。 As shown in FIG. 3, the cutting mechanism 40 includes a cutter 41 disposed below the guide head 32 and a drive device 42 for moving the cutter 41 in the vertical direction. That is, the cutter 41 is movable to an upper position that approaches the guide head 32 and a lower position that is separated from the guide head 32. At this time, the cutter 41 moves along the distal end surface 32 a of the guide head 32. The cutting mechanism 40 moves the cutter 41 up and down to cut the pair of reinforcing film tapes 17 drawn from the pair of slits 31 to form a pair of reinforcing film pieces 16. The length of the reinforcing film piece 16 (the length in the direction orthogonal to the conveying direction of the fastener chain 11) is set to be slightly shorter than the width of the fastener chain 11.
　補強フィルム片搬送手段５０は、一対の補強フィルムテープ１７又は一対の補強フィルム片１６を把持するグリッパ５１と、グリッパ５１を補強フィルムテープ１７の引き出し方向、及びファスナーチェーン１１の搬送方向に沿って移動させるグリッパ駆動手段５２と、を備える。 The reinforcing film piece conveying means 50 moves the gripper 51 that grips the pair of reinforcing film tapes 17 or the pair of reinforcing film pieces 16 and the gripper 51 along the pulling direction of the reinforcing film tape 17 and the conveying direction of the fastener chain 11. Gripper driving means 52 to be operated.
　グリッパ５１は、先端部にファスナーチェーン１１を収容可能な溝５３ａを有する固定ジョー５３と、固定ジョー５３に対向して上下に配置された一対の可動ジョー５４ａ，５４ｂとを備える。可動ジョー５４ａ，５４ｂは、補強フィルムテープ１７の引き出し方向に長尺で、ガイドヘッド３２に対向する先端と、先端と反対側の基端と、先端と基端との間の中間部を有する。この可動ジョー５４ａ，５４ｂは、中間部に設けられた軸５５を中心にして、後述するホルダー５６に揺動自在に支持されている。そして、可動ジョー５４ａ，５４ｂは、その先端が固定ジョー５３の先端から離間するように、不図示のばねで付勢されている。即ち、可動ジョー５４ａ，５４ｂは、固定ジョー５３の先端に接近する位置と、固定ジョー５３の先端から離間する位置とに移動可能である。 The gripper 51 includes a fixed jaw 53 having a groove 53a capable of accommodating the fastener chain 11 at a tip portion thereof, and a pair of movable jaws 54a and 54b disposed up and down facing the fixed jaw 53. The movable jaws 54a and 54b are long in the pull-out direction of the reinforcing film tape 17, and have a distal end facing the guide head 32, a proximal end opposite to the distal end, and an intermediate portion between the distal end and the proximal end. The movable jaws 54a and 54b are supported in a swingable manner by a holder 56, which will be described later, around a shaft 55 provided at the intermediate portion. The movable jaws 54 a and 54 b are urged by a spring (not shown) so that the distal ends thereof are separated from the distal ends of the fixed jaws 53. That is, the movable jaws 54 a and 54 b can move to a position approaching the tip of the fixed jaw 53 and a position away from the tip of the fixed jaw 53.
　固定ジョー５３の先端と可動ジョー５４ａ，５４ｂの先端との間には、一対の開口部５７ａ，５７ｂが開閉可能に形成されている。各開口部５７ａ，５７ｂは、それぞれガイドヘッド３２の一対のスリット３１に臨む位置にある。一対の補強フィルムテープ１７の先端は、スリット３１から突出した時、それぞれ対応する開口部５７ａ，５７ｂに挿入されて把持される。 A pair of openings 57a and 57b are formed to be openable and closable between the distal end of the fixed jaw 53 and the distal ends of the movable jaws 54a and 54b. Each opening 57a, 57b is at a position facing the pair of slits 31 of the guide head 32, respectively. When the ends of the pair of reinforcing film tapes 17 protrude from the slits 31, they are inserted and held in the corresponding openings 57 a and 57 b, respectively.
　また、一対の可動ジョー５４ａ，５４ｂの基端間には隙間５８が形成されている。この隙間５８には、ピストン５９の先端に形成されたカム部５９ａが進入可能に配置されている。ピストン５９は、不図示のばねにより隙間５８から離間するように付勢されている。可動ジョー５４ａ，５４ｂの先端は、ピストン５９のカム部５９ａがばねの弾性力によって隙間５８から離間しているとき、固定ジョー５３の先端から離間している。これにより、可動ジョー５４ａ，５４ｂの先端と固定ジョー５３の先端の間には、開口部５７ａ，５７ｂが開口する。 Further, a gap 58 is formed between the base ends of the pair of movable jaws 54a and 54b. In the gap 58, a cam portion 59a formed at the tip of the piston 59 is disposed so as to be able to enter. The piston 59 is urged away from the gap 58 by a spring (not shown). The distal ends of the movable jaws 54a and 54b are separated from the distal end of the fixed jaw 53 when the cam portion 59a of the piston 59 is separated from the gap 58 by the elastic force of the spring. Thereby, openings 57 a and 57 b are opened between the distal ends of the movable jaws 54 a and 54 b and the distal end of the fixed jaw 53.
　そして、グリッパ５１は、一対の補強フィルムテープ１７を開口部５７ａ，５７ｂに挿入した後、ピストン５９のカム部５９ａを隙間５８に進入させる。これにより、一対の可動ジョー５４ａ，５４ｂは、軸５５を中心にして揺動し、開口部５７ａ，５７ｂを閉じる。この時、固定ジョー５３の先端と可動ジョー５４ａ，５４ｂの先端とが一対の補強フィルムテープ１７を把持する。 The gripper 51 inserts the cam portion 59a of the piston 59 into the gap 58 after inserting the pair of reinforcing film tapes 17 into the openings 57a and 57b. As a result, the pair of movable jaws 54a and 54b swing around the shaft 55 and close the openings 57a and 57b. At this time, the distal end of the fixed jaw 53 and the distal ends of the movable jaws 54 a and 54 b grip the pair of reinforcing film tapes 17.
　グリッパ駆動手段５２は、グリッパ５１を補強フィルムテープ１７の引き出し方向、及びファスナーチェーン１１の搬送方向に沿って移動させる。このグリッパ駆動手段５２は、ファスナーチェーン１１に対して、補強フィルムテープ供給手段３０と反対側に配設されている。グリッパ駆動手段５２は、ホルダー５６に連結されたサーボモータ６８と、サーボモータ６８を取り付けた移動台６２と、移動台６２に連結されたシリンダ装置６１を備える。サーボモータ６８は、グリッパ５１を補強フィルムテープ１７の引き出し方向に沿って移動させる。シリンダ装置６１は、移動台６２をファスナーチェーン１１の搬送方向に沿って移動させることで、グリッパ５１をファスナーチェーン１１の搬送方向に沿って移動させる。 The gripper driving means 52 moves the gripper 51 along the pulling-out direction of the reinforcing film tape 17 and the conveying direction of the fastener chain 11. The gripper driving means 52 is disposed on the side opposite to the reinforcing film tape supply means 30 with respect to the fastener chain 11. The gripper driving means 52 includes a servo motor 68 connected to the holder 56, a moving table 62 to which the servo motor 68 is attached, and a cylinder device 61 connected to the moving table 62. The servo motor 68 moves the gripper 51 along the pulling direction of the reinforcing film tape 17. The cylinder device 61 moves the gripper 51 along the conveyance direction of the fastener chain 11 by moving the movable table 62 along the conveyance direction of the fastener chain 11.
　移動台６２は、ファスナーチェーン１１の搬送方向と直交する方向に離間して配置された第１壁６３と第２壁６４を備える。第１壁６３と第２壁６４との間には、一対のガイドロッド６５が、ファスナーチェーン１１の搬送方向に離間して、互いに平行に配置されている。そして、各ガイドロッド６５は、ファスナーチェーン１１の搬送方向と直交する方向（補強フィルムテープ１７の引き出し方向）に延びている。一対のガイドロッド６５には、グリッパ５１を保持するホルダー５６が摺動自在に取り付けられている。 The moving table 62 includes a first wall 63 and a second wall 64 that are spaced apart from each other in a direction orthogonal to the conveying direction of the fastener chain 11. Between the first wall 63 and the second wall 64, a pair of guide rods 65 are arranged in parallel to each other while being separated from each other in the conveying direction of the fastener chain 11. Each guide rod 65 extends in a direction perpendicular to the conveying direction of the fastener chain 11 (the direction in which the reinforcing film tape 17 is pulled out). A holder 56 that holds the gripper 51 is slidably attached to the pair of guide rods 65.
　また、移動台６２の第１壁６３と第２壁６４の間には、ボールねじ機構が配設されている。ボールねじ機構は、ファスナーチェーン１１の搬送方向と直交する方向に延びるねじ軸６６と、ねじ軸６６に螺合するボールナット６７を備える。ホルダー５６は、ボールナット６７を介して、サーボモータ６８に連結されている。ねじ軸６６は、第２壁６４に固定されたサーボモータ６８によって回転駆動される。この時、ボールナット６７がねじ軸６６に沿って、ファスナーチェーン１１の搬送方向と直交する方向に移動する。これにより、ホルダー５６は、グリッパ５１と共に、一対のガイドロッド６５に案内されながら、ファスナーチェーン１１の搬送方向と直交する方向に移動する。 Further, a ball screw mechanism is disposed between the first wall 63 and the second wall 64 of the moving table 62. The ball screw mechanism includes a screw shaft 66 extending in a direction orthogonal to the conveying direction of the fastener chain 11 and a ball nut 67 that is screwed onto the screw shaft 66. The holder 56 is connected to a servo motor 68 via a ball nut 67. The screw shaft 66 is rotationally driven by a servo motor 68 fixed to the second wall 64. At this time, the ball nut 67 moves along the screw shaft 66 in a direction orthogonal to the conveying direction of the fastener chain 11. As a result, the holder 56 moves in the direction orthogonal to the conveying direction of the fastener chain 11 while being guided by the pair of guide rods 65 together with the gripper 51.
　このように、グリッパ５１はサーボモータ６８によって駆動されるので、ファスナーチェーン１１の搬送方向と直交する方向に沿う任意の位置で停止可能である。具体的には、グリッパ５１が、スリット３１で案内される一対の補強フィルムテープ１７の先端をグリッパ５１で把持する把持位置Ｐ１、一対の補強フィルムテープ１７を切断する切断位置Ｐ２、一対の補強フィルム片１６を把持して待機する待機位置Ｐ３、及び熱接着装置７０から退避する退避位置Ｐ４の４ヶ所で停止可能である。 Thus, since the gripper 51 is driven by the servo motor 68, the gripper 51 can be stopped at any position along the direction orthogonal to the conveying direction of the fastener chain 11. Specifically, the gripper 51 holds the leading ends of the pair of reinforcing film tapes 17 guided by the slits 31 with the gripper 51, the cutting position P2 that cuts the pair of reinforcing film tapes 17, and the pair of reinforcing films. It can be stopped at four positions: a standby position P3 that holds the piece 16 and waits, and a retreat position P4 that retreats from the thermal bonding apparatus 70.
　シリンダ装置６１は、一端が移動台６２に連結されたピストンロッド６９を備える。シリンダ装置６１は、ファスナーチェーン１１の搬送方向に沿って、ピストンロッド６９を伸縮可能である。これにより、グリッパ５１は、シリンダ装置６１のピストンロッド６９が伸縮することで、ファスナーチェーン１１の搬送方向に沿って移動する。即ち、グリッパ５１は、待機位置Ｐ３と、待機位置Ｐ３よりもファスナーチェーン１１の搬送方向上流側に位置する接着位置Ｐ５との間で往復移動する。接着位置Ｐ５は、補強フィルム片１６をファスナーチェーン１１のスペース部１２に接着する位置である。 The cylinder device 61 includes a piston rod 69 having one end connected to the moving table 62. The cylinder device 61 can extend and retract the piston rod 69 along the conveying direction of the fastener chain 11. Thereby, the gripper 51 moves along the conveyance direction of the fastener chain 11 by the expansion and contraction of the piston rod 69 of the cylinder device 61. That is, the gripper 51 reciprocates between the standby position P3 and the adhesion position P5 located on the upstream side of the standby position P3 in the transport direction of the fastener chain 11. The adhesion position P5 is a position where the reinforcing film piece 16 is adhered to the space portion 12 of the fastener chain 11.
　熱接着装置７０は、補強フィルムテープ供給手段３０から引き出された一対の補強フィルムテープ１７とファスナーチェーン１１とが、上面視で交差する位置（待機位置Ｐ３）に対して、ファスナーチェーン１１の搬送方向にずれた位置（本実施形態では、待機位置Ｐ３に対して上流側の接着位置Ｐ５）に配置されている。この熱接着装置７０は、補強フィルム片１６接し、補強フィルム片１６を加熱するダイプレートを備える。ダイプレートは、ファスナーチェーン１１の搬送経路を挟んで対向して配置された第１ダイプレート７１と第２ダイプレート７２とを備える。第１ダイプレート７１は、ファスナーチェーン１１の上方に配置されている。第２ダイプレート７２は、ファスナーチェーン１１の下方に配置されている。熱接着装置７０は、補強フィルム片１６を加熱するためにヒータ７３を備えている。具体的には、第１ダイプレート７１と第２ダイプレート７２が、ヒータ７３を内蔵している。第１ダイプレート７１及び第２ダイプレート７２は、不図示の駆動装置により上下動可能である。即ち、第１ダイプレート７１及び第２ダイプレート７２は、ファスナーチェーン１１に接着された補強フィルム片１６に離間する位置と接近する位置とに移動可能である。熱接着装置７０は、ファスナーチェーン１１と、ファスナーチェーン１１（スペース部１２）の上下面に対向して配置した一対の補強フィルム片１６とを、第１ダイプレート７１と第２ダイプレート７２とで挟持して加熱する。これにより、補強フィルム片１６が溶融してファスナーチェーン１１の上下面に接着される。 The heat bonding apparatus 70 is configured to convey the fastener chain 11 with respect to a position (standby position P3) where the pair of the reinforcing film tape 17 drawn out from the reinforcing film tape supply means 30 and the fastener chain 11 intersect in a top view. (In this embodiment, it is disposed at the upstream adhesion position P5 with respect to the standby position P3). The thermal bonding apparatus 70 includes a die plate that contacts the reinforcing film piece 16 and heats the reinforcing film piece 16. The die plate includes a first die plate 71 and a second die plate 72 that are arranged to face each other across the conveyance path of the fastener chain 11. The first die plate 71 is disposed above the fastener chain 11. The second die plate 72 is disposed below the fastener chain 11. The thermal bonding apparatus 70 includes a heater 73 for heating the reinforcing film piece 16. Specifically, the first die plate 71 and the second die plate 72 have a heater 73 built therein. The first die plate 71 and the second die plate 72 can be moved up and down by a driving device (not shown). That is, the first die plate 71 and the second die plate 72 are movable between a position separating from the reinforcing film piece 16 bonded to the fastener chain 11 and a position approaching the reinforcing film piece 16. The thermal bonding apparatus 70 includes a fastener chain 11 and a pair of reinforcing film pieces 16 arranged to face the upper and lower surfaces of the fastener chain 11 (space portion 12) with a first die plate 71 and a second die plate 72. Hold and heat. Thereby, the reinforcing film piece 16 is melted and bonded to the upper and lower surfaces of the fastener chain 11.
　フィルム片冷却装置８０は、熱接着装置７０よりもファスナーチェーン１１の搬送方向下流側に配置されている。このフィルム片冷却装置８０は、ファスナーチェーン１１に接着された補強フィルム片１６接し、補強フィルム片１６を冷却する冷却部材を備える。冷却部材は、ファスナーチェーン１１の搬送経路を挟んで対向して配置された第１冷却部材８１と第２冷却部材８２とを備える。第１冷却部材８１は、ファスナーチェーン１１の上方に配置されている。第２冷却部材８２は、ファスナーチェーン１１の下方に配置されている。第１冷却部材８１及び第２冷却部材８２は、不図示の駆動装置により上下動可能である。即ち、第１冷却部材８１及び第２冷却部材８２は、ファスナーチェーン１１に接着された補強フィルム片１６に離間する位置と接近する位置とに移動可能である。 The film piece cooling device 80 is arranged on the downstream side in the transport direction of the fastener chain 11 from the thermal bonding device 70. The film piece cooling device 80 includes a cooling member that contacts the reinforcing film piece 16 bonded to the fastener chain 11 and cools the reinforcing film piece 16. The cooling member includes a first cooling member 81 and a second cooling member 82 that are arranged to face each other across the conveyance path of the fastener chain 11. The first cooling member 81 is disposed above the fastener chain 11. The second cooling member 82 is disposed below the fastener chain 11. The first cooling member 81 and the second cooling member 82 can be moved up and down by a driving device (not shown). That is, the first cooling member 81 and the second cooling member 82 are movable between a position where the reinforcing film piece 16 bonded to the fastener chain 11 is separated and a position where the reinforcing film piece 16 is approached.
　第１冷却部材８１及び第２冷却部材８２は、補強フィルム片１６の熱容量よりもはるかに大きい熱容量を有する金属材料で形成されている。そして、第１冷却部材８１及び第２冷却部材８２で、補強フィルム片１６をファスナーチェーン１１と共に挟持することで、補強フィルム片１６の熱を吸収して冷却する。即ち、補強フィルム片１６の熱が、補強フィルム片１６と第１冷却部材８１及び第２冷却部材８２との接触部位から、第１冷却部材８１及び第２冷却部材８２に伝熱する。これにより、補強フィルム片１６は急速に冷却される。なお、第１冷却部材８１及び第２冷却部材８２の素材は、金属材料に限定されず、熱容量が大きく且つ熱伝達率が大きな材料であればよい。また、第１冷却部材８１及び第２冷却部材８２は、循環供給する冷媒により積極的に冷却されるようにしてもよい。 The first cooling member 81 and the second cooling member 82 are made of a metal material having a heat capacity much larger than the heat capacity of the reinforcing film piece 16. The first cooling member 81 and the second cooling member 82 sandwich the reinforcing film piece 16 together with the fastener chain 11 to absorb the heat of the reinforcing film piece 16 and cool it. That is, the heat of the reinforcing film piece 16 is transferred from the contact portion between the reinforcing film piece 16 and the first cooling member 81 and the second cooling member 82 to the first cooling member 81 and the second cooling member 82. Thereby, the reinforcing film piece 16 is rapidly cooled. In addition, the raw material of the 1st cooling member 81 and the 2nd cooling member 82 is not limited to a metal material, What is necessary is just a material with a large heat capacity and a large heat transfer rate. In addition, the first cooling member 81 and the second cooling member 82 may be positively cooled by a refrigerant that is circulated.
　次に、上記補強フィルム接着装置１０によりファスナーチェーン１１に補強フィルム片１６を接着する方法について説明する。なお、グリッパ５１は、一対の補強フィルム片１６を把持して待機位置Ｐ３で待機しているものとして説明を始める。即ち、待機位置Ｐ３におけるグリッパ５１は、ピストン５９のカム部５９ａが一対の可動ジョー５４ａ，５４ｂの基端間の隙間５８に進入して、開口部５７ａ，５７ｂを閉じる。これにより、可動ジョー５４ａ，５４ｂの先端と固定ジョー５３の先端は、一対の補強フィルム片１６を把持している。 Next, a method for bonding the reinforcing film piece 16 to the fastener chain 11 using the reinforcing film bonding apparatus 10 will be described. The gripper 51 starts the description assuming that the gripper 51 holds the pair of reinforcing film pieces 16 and is waiting at the standby position P3. That is, in the gripper 51 at the standby position P3, the cam portion 59a of the piston 59 enters the gap 58 between the base ends of the pair of movable jaws 54a and 54b, and closes the openings 57a and 57b. As a result, the distal ends of the movable jaws 54 a and 54 b and the distal end of the fixed jaw 53 grip the pair of reinforcing film pieces 16.
　先ず、ファスナーチェーン搬送手段２０は、駆動ローラ２１を回転させて、ファスナーチェーン１１を搬送する。この時、感知手段２４は、感知ローラ２５が、ファスナーチェーン１１のファスナーエレメント列１５に接触しながら回転している。やがて、感知ローラ２５は、ファスナーチェーン１１のスペース部１２が感知ローラ２５の位置に達すると、感知ローラ２５がファスナーエレメント列１５との接触から解放され、スペース部１２に侵入する。この時、感知ローラ２５は、一対のファスナーテープのテープ側縁部１３ａ間に形成された隙間Ｓに入り込む。これにより、感知手段２４は、感知ローラ２５が下方へ移動するとともに、揺動レバー２６が揺動することでスペース部１２を検出する。 First, the fastener chain conveying means 20 conveys the fastener chain 11 by rotating the drive roller 21. At this time, the sensing means 24 rotates while the sensing roller 25 is in contact with the fastener element row 15 of the fastener chain 11. Eventually, when the space portion 12 of the fastener chain 11 reaches the position of the detection roller 25, the detection roller 25 is released from contact with the fastener element row 15 and enters the space portion 12. At this time, the sensing roller 25 enters the gap S formed between the tape side edges 13a of the pair of fastener tapes. As a result, the sensing means 24 detects the space portion 12 as the sensing roller 25 moves downward and the rocking lever 26 rocks.
　ファスナーチェーン搬送手段２０は、スペース部１２が感知手段２４によって検出されると、スペース部１２を熱接着装置７０の第１ダイプレート７１と第２ダイプレート７２との間までファスナーチェーン１１を更に搬送して停止させる。 When the space portion 12 is detected by the sensing means 24, the fastener chain conveying means 20 further conveys the fastener chain 11 to the space portion 12 between the first die plate 71 and the second die plate 72 of the thermal bonding apparatus 70. And stop.
　このようなファスナーチェーン１１の搬送は、測長手段がファスナーチェーン１１の搬送距離を測長することで停止する。この測長手段として、駆動ローラ２１に取り付けたエンコーダを採用できる。エンコーダは、感知手段２４がスペース部１２を検出した後、駆動ローラ２１の回転角度に基づき、ファスナーチェーン１１の搬送距離を測長する。これにより、ファスナーチェーン搬送手段２０は、ファスナーチェーン１１の搬送距離が、予め設定された距離（感知手段２４及び熱接着装置７０間の距離）に達した時、駆動ローラ２１の回転を停止して、ファスナーチェーン１１の搬送を停止する。 Such conveyance of the fastener chain 11 is stopped when the length measuring means measures the conveyance distance of the fastener chain 11. As this length measuring means, an encoder attached to the drive roller 21 can be employed. The encoder measures the conveyance distance of the fastener chain 11 based on the rotation angle of the drive roller 21 after the sensing means 24 detects the space portion 12. Thereby, the fastener chain conveying means 20 stops the rotation of the drive roller 21 when the conveying distance of the fastener chain 11 reaches a preset distance (distance between the sensing means 24 and the thermal bonding apparatus 70). Then, the conveyance of the fastener chain 11 is stopped.
　そして、グリッパ駆動手段５２は、シリンダ装置６１を作動させてピストンロッド６９を収縮させる。これにより、待機位置Ｐ３で待機していたグリッパ５１は、移動台６２と共に、ファスナーチェーン１１の搬送方向上流側に向けて移動する。即ち、グリッパ５１は、接着位置Ｐ５に移動する。また、一対の補強フィルム片１６は、それぞれファスナーチェーン１１の上下面に対向した状態で、グリッパ５１に把持されながら第１ダイプレート７１と第２ダイプレート７２との間に移動する。 Then, the gripper driving means 52 operates the cylinder device 61 to contract the piston rod 69. As a result, the gripper 51 that has been waiting at the standby position P <b> 3 moves together with the moving base 62 toward the upstream side in the transport direction of the fastener chain 11. That is, the gripper 51 moves to the adhesion position P5. Further, the pair of reinforcing film pieces 16 move between the first die plate 71 and the second die plate 72 while being gripped by the gripper 51 in a state of facing the upper and lower surfaces of the fastener chain 11.
　なお、グリッパ５１は、ファスナーチェーン１１の搬送と同時に、待機位置Ｐ３から接着位置Ｐ５へ移動してもよい。 The gripper 51 may move from the standby position P3 to the adhesion position P5 simultaneously with the conveyance of the fastener chain 11.
　次いで、第１ダイプレート７１と第２ダイプレート７２に設けられた不図示の仮押さえ機構が、一対の補強フィルム片１６とファスナーチェーン１１との重ね合わせ位置がずれないように、一対の補強フィルム片１６を仮押えする。次いで、グリッパ５１は、開口部５７ａ，５７ｂを開口させ、一対の補強フィルム片１６の把持を解除する。 Next, the temporary pressing mechanism (not shown) provided on the first die plate 71 and the second die plate 72 prevents the overlapping positions of the pair of reinforcing film pieces 16 and the fastener chain 11 from being shifted. Temporarily press the piece 16. Next, the gripper 51 opens the openings 57 a and 57 b and releases the grip of the pair of reinforcing film pieces 16.
　次いで、グリッパ駆動手段５２は、サーボモータ６８を駆動してねじ軸６６を回転させることで、グリッパ５１を接着位置Ｐ５から退避位置Ｐ４に移動させる。これにより、グリッパ５１は、第１ダイプレート７１及び第２ダイプレート７２が補強フィルム片１６を接着するためにファスナーチェーン１１に接近移動（上下移動）した時、第１ダイプレート７１及び第２ダイプレート７２との接触を回避する。 Next, the gripper driving means 52 drives the servo motor 68 to rotate the screw shaft 66, thereby moving the gripper 51 from the adhesion position P5 to the retracted position P4. As a result, when the first die plate 71 and the second die plate 72 are moved closer (up and down) to the fastener chain 11 to bond the reinforcing film piece 16, the gripper 51 is moved to the first die plate 71 and the second die plate 71. Avoid contact with plate 72.
　次いで、第１ダイプレート７１が下降すると共に、第２ダイプレート７２が上昇する。これにより、第１ダイプレート７１と第２ダイプレート７２は、ファスナーチェーン１１の上下面に対向配置された一対の補強フィルム片１６をファスナーチェーン１１と共に挟持する。そして、第１ダイプレート７１と第２ダイプレート７２は、一対の補強フィルム片１６を加熱して、一対の補強フィルム片１６をファスナーチェーン１１の上下面に接着する。 Next, the first die plate 71 is lowered and the second die plate 72 is raised. Thus, the first die plate 71 and the second die plate 72 sandwich the pair of reinforcing film pieces 16 disposed on the upper and lower surfaces of the fastener chain 11 together with the fastener chain 11. The first die plate 71 and the second die plate 72 heat the pair of reinforcing film pieces 16 and adhere the pair of reinforcing film pieces 16 to the upper and lower surfaces of the fastener chain 11.
　一対の補強フィルム片１６は、ファスナーチェーン１１に接着するのに十分な時間、熱接着装置７０により加熱される。例えば、超音波による短時間加熱では、止水層や撥水処理層が表面に形成されたファスナーテープ１３に補強フィルム片１６を接着する場合、十分な接着強度が得られないことがある。本実施形態の熱接着装置７０は、補強フィルム片１６を十分に加熱するので、補強フィルム片１６とファスナーチェーン１１との接着強度が向上する。 The pair of reinforcing film pieces 16 are heated by the heat bonding apparatus 70 for a time sufficient to bond to the fastener chain 11. For example, when the reinforcing film piece 16 is bonded to the fastener tape 13 having a water-stopping layer or a water-repellent treatment layer formed on the surface by short-time heating with ultrasonic waves, sufficient adhesive strength may not be obtained. Since the thermal bonding apparatus 70 of the present embodiment sufficiently heats the reinforcing film piece 16, the adhesive strength between the reinforcing film piece 16 and the fastener chain 11 is improved.
　グリッパ駆動手段５２は、熱接着装置７０が補強フィルム片１６をファスナーチェーン１１に接着している間に、これと並行してシリンダ装置６１を作動させてピストンロッド６９を伸長させる。これにより、退避位置Ｐ４にあるグリッパ５１は、移動台６２と共に、ファスナーチェーン１１の搬送方向下流側に向けて移動する。即ち、グリッパ５１は、待機位置Ｐ３に移動する。 The gripper driving means 52 operates the cylinder device 61 and extends the piston rod 69 in parallel with this while the thermal bonding device 70 bonds the reinforcing film piece 16 to the fastener chain 11. As a result, the gripper 51 at the retracted position P4 moves together with the moving table 62 toward the downstream side in the transport direction of the fastener chain 11. That is, the gripper 51 moves to the standby position P3.
　更に、グリッパ駆動手段５２は、サーボモータ６８によりねじ軸６６を回転させることで、ボールナット６７に固定されたホルダー５６を移動させる。これにより、グリッパ５１は、補強フィルムテープ１７を把持可能な把持位置Ｐ１に移動する。 Further, the gripper driving means 52 moves the holder 56 fixed to the ball nut 67 by rotating the screw shaft 66 by the servo motor 68. As a result, the gripper 51 moves to a gripping position P1 at which the reinforcing film tape 17 can be gripped.
　このとき、グリッパ５１は、ファスナーチェーン１１の搬送経路を横切ってファスナーチェーン１１の搬送方向と直交する方向に移動する。ファスナーチェーン１１は、固定ジョー５３の溝５３ａに収容されるので、グリッパ５１の移動の障害とはならない。 At this time, the gripper 51 moves in a direction orthogonal to the conveying direction of the fastener chain 11 across the conveying path of the fastener chain 11. Since the fastener chain 11 is accommodated in the groove 53a of the fixed jaw 53, it does not hinder the movement of the gripper 51.
　グリッパ５１は、待機位置Ｐ３から把持位置Ｐ１に移動した時、補強フィルムテープ供給手段３０のガイドヘッド３２に当接する。この時、グリッパ５１は、ばねの弾性力に抗して、ガイドヘッド３２を補強フィルムテープ１７の引き出し方向と逆方向に移動させる。これにより、一対の補強フィルムテープ１７の先端が、ガイドヘッド３２の移動距離分だけ、一対のスリット３１から突出する。そして、一対の補強フィルムテープ１７の先端が、グリッパ５１の開口部５７ａ，５７ｂに挿入される。 The gripper 51 comes into contact with the guide head 32 of the reinforcing film tape supply means 30 when moving from the standby position P3 to the gripping position P1. At this time, the gripper 51 moves the guide head 32 in the direction opposite to the pulling-out direction of the reinforcing film tape 17 against the elastic force of the spring. As a result, the tips of the pair of reinforcing film tapes 17 protrude from the pair of slits 31 by the moving distance of the guide head 32. Then, the ends of the pair of reinforcing film tapes 17 are inserted into the openings 57 a and 57 b of the gripper 51.
　ここで、ピストン５９のカム部５９ａが一対の可動ジョー５４ａ，５４ｂの基端間の隙間５８に進入する。これにより、可動ジョー５４ａ，５４ｂが軸５５を中心として揺動し、開口部５７ａ，５７ｂを閉じる。これにより、固定ジョー５３と一対の可動ジョー５４ａ，５４ｂとが、一対の補強フィルムテープ１７の先端を把持する。 Here, the cam portion 59a of the piston 59 enters the gap 58 between the base ends of the pair of movable jaws 54a and 54b. As a result, the movable jaws 54a and 54b swing around the shaft 55 and close the openings 57a and 57b. As a result, the fixed jaw 53 and the pair of movable jaws 54 a and 54 b grip the tips of the pair of reinforcing film tapes 17.
　次いで、グリッパ駆動手段５２は、サーボモータ６８を駆動し、グリッパ５１を切断位置Ｐ２まで移動させて停止させる。これにより、グリッパ５１によって把持されている一対の補強フィルムテープ１７は、ファスナーチェーン１１の幅より僅かに少ない長さだけスリット３１から引き出される。また、ガイドヘッド３２は、グリッパ５１の移動と同時に、ばねの弾性力により元の位置に復帰する。 Next, the gripper driving means 52 drives the servo motor 68 to move the gripper 51 to the cutting position P2 and stop it. As a result, the pair of reinforcing film tapes 17 held by the gripper 51 are pulled out from the slit 31 by a length slightly smaller than the width of the fastener chain 11. The guide head 32 returns to the original position by the elastic force of the spring simultaneously with the movement of the gripper 51.
　ここで、切断機構４０は、駆動装置４２によりカッタ４１を上昇させる。これにより、切断機構４０は、一対の補強フィルムテープ１７をガイドヘッド３２の先端面３２ａに沿って切断して、一対の補強フィルム片１６を形成する。 Here, the cutting mechanism 40 raises the cutter 41 by the driving device 42. As a result, the cutting mechanism 40 cuts the pair of reinforcing film tapes 17 along the distal end surface 32 a of the guide head 32 to form the pair of reinforcing film pieces 16.
　そして、グリッパ駆動手段５２は、更にサーボモータ６８を駆動し、一対の補強フィルム片１６を把持するグリッパ５１を待機位置Ｐ３に移動させる。グリッパ駆動手段５２は、熱接着装置７０による補強フィルム片１６の接着が終了するまで、グリッパ５１を待機位置Ｐ３に待機させる。 The gripper driving means 52 further drives the servo motor 68 to move the gripper 51 that holds the pair of reinforcing film pieces 16 to the standby position P3. The gripper driving means 52 causes the gripper 51 to wait at the standby position P3 until the adhesion of the reinforcing film piece 16 by the thermal bonding apparatus 70 is completed.
　このように、補強フィルム接着装置１０は、熱接着装置７０による補強フィルム片１６の接着工程と、グリッパ５１の退避位置Ｐ４から把持位置Ｐ１への移動、一対の補強フィルムテープ１７の把持、切断位置Ｐ２での切断、及び待機位置Ｐ３での待機の各工程とが、並行して同時に行われるので、サイクル時間が大幅に短縮される。 As described above, the reinforcing film bonding apparatus 10 includes the bonding process of the reinforcing film piece 16 by the thermal bonding apparatus 70, the movement of the gripper 51 from the retracted position P4 to the holding position P1, the holding of the pair of reinforcing film tapes 17, and the cutting position. Since the cutting process at P2 and the standby process at the standby position P3 are simultaneously performed in parallel, the cycle time is greatly shortened.
　そして、熱接着装置７０は、補強フィルム片１６とファスナーチェーン１１の接着が終了すると、第１ダイプレート７１及び第２ダイプレート７２がファスナーチェーン１１から上下に離間する。そして、図４に示すように、ファスナーチェーン搬送手段２０が再び作動して、ファスナーチェーン１１を搬送する。そして、ファスナーチェーン搬送手段２０は、ファスナーチェーン１１に接着された補強フィルム片１６が、フィルム片冷却装置８０の位置と上面視で重なる位置に達すると、ファスナーチェーン１１の搬送を停止する。 In the thermal bonding apparatus 70, when the bonding between the reinforcing film piece 16 and the fastener chain 11 is completed, the first die plate 71 and the second die plate 72 are separated from the fastener chain 11 in the vertical direction. And as shown in FIG. 4, the fastener chain conveyance means 20 act | operates again, and the fastener chain 11 is conveyed. Then, when the reinforcing film piece 16 bonded to the fastener chain 11 reaches a position overlapping the position of the film piece cooling device 80 in a top view, the fastener chain conveying means 20 stops conveying the fastener chain 11.
　ファスナーチェーン搬送手段２０は、ファスナーチェーン１１を熱接着装置７０の下方位置からフィルム片冷却装置８０の下方位置まで搬送する時、駆動ローラ２１に取り付けた不図示のエンコーダが、ファスナーチェーン１１の搬送距離を測長する。ファスナーチェーン搬送手段２０は、ファスナーチェーン１１の搬送距離が、予め設定された搬送距離（熱接着装置７０及びフィルム片冷却装置８０間の距離）に達した時、駆動ローラ２１の回転を停止して、ファスナーチェーン１１の搬送を停止する。 When the fastener chain conveying means 20 conveys the fastener chain 11 from the lower position of the thermal bonding apparatus 70 to the lower position of the film piece cooling apparatus 80, an encoder (not shown) attached to the driving roller 21 causes the conveying distance of the fastener chain 11 to be fixed. Measure the length. The fastener chain conveying means 20 stops the rotation of the driving roller 21 when the conveying distance of the fastener chain 11 reaches a preset conveying distance (distance between the thermal bonding device 70 and the film piece cooling device 80). Then, the conveyance of the fastener chain 11 is stopped.
　フィルム片冷却装置８０は、第１冷却部材８１が下降すると共に、第２冷却部材８２が上昇する。これにより、第１冷却部材８１と第２冷却部材８２は、ファスナーチェーン１１の上下面に接着された一対の補強フィルム片１６をファスナーチェーン１１と共に挟持する。そして、第１冷却部材８１と第２冷却部材８２は、補強フィルム片１６の熱を吸収して、補強フィルム片１６を冷却する。 In the film piece cooling device 80, the first cooling member 81 is lowered and the second cooling member 82 is raised. Accordingly, the first cooling member 81 and the second cooling member 82 sandwich the pair of reinforcing film pieces 16 bonded to the upper and lower surfaces of the fastener chain 11 together with the fastener chain 11. The first cooling member 81 and the second cooling member 82 absorb the heat of the reinforcing film piece 16 and cool the reinforcing film piece 16.
　このように、一対の補強フィルム片１６は、ファスナーチェーン１１に接着された後、自然冷却させることなく、フィルム片冷却装置８０で直ちに冷却される。これにより、加熱時に発生する気泡により、補強フィルム片１６に白濁が発生することを防止する。 In this way, the pair of reinforcing film pieces 16 are immediately cooled by the film piece cooling device 80 without being naturally cooled after being bonded to the fastener chain 11. This prevents white turbidity from occurring in the reinforcing film piece 16 due to bubbles generated during heating.
　また、グリッパ駆動手段５２は、補強フィルム片１６の冷却と同時に、シリンダ装置６１を作動させて、待機位置Ｐ３で待機していたグリッパ５１を接着位置Ｐ５に移動させる。グリッパ５１は、一対の補強フィルム片１６を把持しながら移動する。一対の補強フィルム片１６は、ファスナーチェーン１１の上下面に対向した状態で、第１ダイプレート７１と第２ダイプレート７２との間に位置する。 Further, the gripper driving means 52 operates the cylinder device 61 simultaneously with the cooling of the reinforcing film piece 16 to move the gripper 51 that has been waiting at the standby position P3 to the adhesion position P5. The gripper 51 moves while gripping the pair of reinforcing film pieces 16. The pair of reinforcing film pieces 16 are positioned between the first die plate 71 and the second die plate 72 in a state of facing the upper and lower surfaces of the fastener chain 11.
　そして、補強フィルム片１６の冷却が終了した後、ファスナーチェーン搬送手段２０が再び作動して、ファスナーチェーン１１を搬送する。ファスナーチェーン搬送手段２０は、ファスナーチェーン１１のスペース部１２が、熱接着装置７０の第１ダイプレート７１と第２ダイプレート７２との間に搬送されると、ファスナーチェーン１１の搬送を停止する。そして、熱接着装置７０は、一対の補強フィルム片１６をファスナーチェーン１１のスペース部１２に接着する。補強フィルム接着装置１０は、以後、同様の動作を繰り返し行い、補強フィルム片１６をファスナーチェーン１１のスペース部１２に順次接着する。 Then, after the cooling of the reinforcing film piece 16 is finished, the fastener chain conveying means 20 is actuated again to convey the fastener chain 11. When the space portion 12 of the fastener chain 11 is transported between the first die plate 71 and the second die plate 72 of the thermal bonding apparatus 70, the fastener chain transport means 20 stops the transport of the fastener chain 11. Then, the heat bonding apparatus 70 bonds the pair of reinforcing film pieces 16 to the space portion 12 of the fastener chain 11. Thereafter, the reinforcing film bonding apparatus 10 repeats the same operation to sequentially bond the reinforcing film pieces 16 to the space portion 12 of the fastener chain 11.
　上記した一連の動作により、図５に示すように、一対のファスナーテープ１３のスペース部１２に、補強フィルム片１６が接着されたファスナーチェーン１１が得られる。補強フィルム片１６は、熱接着装置７０により比較的長時間加熱されて接着されるので、ファスナーチェーン１１に強固に接着され、接着強度が高い。また、加熱接着した補強フィルム片１６は、フィルム片冷却装置８０によって直ちに冷却されるので、白濁の発生が防止される。 By the series of operations described above, the fastener chain 11 in which the reinforcing film piece 16 is bonded to the space portion 12 of the pair of fastener tapes 13 is obtained as shown in FIG. Since the reinforcing film piece 16 is heated and bonded by the heat bonding apparatus 70 for a relatively long time, it is firmly bonded to the fastener chain 11 and has high bonding strength. Further, since the heat-bonded reinforcing film piece 16 is immediately cooled by the film piece cooling device 80, the occurrence of white turbidity is prevented.
　以上説明したように、本実施形態の補強フィルム接着装置１０は、ファスナーチェーン搬送手段２０と、補強フィルムテープ供給手段３０と、補強フィルムテープ１７の切断機構４０と、グリッパ５１及びグリッパ駆動手段５２を備える補強フィルム片搬送手段５０と、熱接着装置７０と、を備える。この補強フィルム接着装置１０は、熱接着装置７０よりも搬送方向下流側に、接着された一対の補強フィルム片１６を冷却するフィルム片冷却装置８０が配置されるため、ファスナーチェーン１１と補強フィルム片１６との接着強度を確保すると共に、補強フィルム片１６に白濁が発生することを防止することができる。これにより、商品価値の低下を防止することができる。 As described above, the reinforcing film bonding apparatus 10 according to the present embodiment includes the fastener chain conveying means 20, the reinforcing film tape supplying means 30, the cutting mechanism 40 for the reinforcing film tape 17, the gripper 51, and the gripper driving means 52.

It is effective for bonding.
　また、本実施形態の補強フィルム接着装置１０は、フィルム片冷却装置８０が、互いに対向して配置された第１冷却部材８１と第２冷却部材８２と、を備える。これにより、第１冷却部材８１と第２冷却部材８２は、ファスナーチェーン１１に接着された補強フィルム片１６をファスナーチェーン１１と共に挟持して効率的に冷却し、補強フィルム片１６に白濁が発生することを防止することができる。 Further, in the reinforcing film bonding apparatus 10 of the present embodiment, the film piece cooling device 80 includes a first cooling member 81 and a second cooling member 82 arranged to face each other. As a result, the first cooling member 81 and the second cooling member 82 efficiently cool the sandwiched reinforcing film piece 16 adhered to the fastener chain 11 together with the fastener chain 11, and the reinforcing film piece 16 becomes clouded. This can be prevented.
