Description

【０００１】
【産業上の利用分野】
本発明は、帯状の未加硫ゴムからなる帯状ゴムシート材料を繋ぐ帯状ゴムシート材料接続装置に関し、更に詳しくは、離型シート付き帯状ゴムシート材料相互の接続を自動的に行うことができるようにした帯状ゴムシート材料接続装置に関する。
【０００２】
【従来の技術】
従来、例えば、タイヤの製造におけるスチールベルトのエッジ部の保護に用いられる帯状の未加硫ゴムからなる帯状ゴムシート材料は、一般に離型シートが一方の面に貼着された状態で、２０〜３０mm程度の所定幅に分割され、ロールに巻き取られてストックされる。そして、使用される際には、この巻き取りロールから引き出されるようになっている。
【０００３】
上記のような離型シート付き帯状ゴムシート材料は、ロールに巻き取られる場合、一般的に約３００ｍ程度が限度である一方、使用時にはロールから４０〜５０ｍ／分の搬出速度で引き出されるため、約６分間隔で帯状ゴムシート材料を次のロールの帯状ゴムシート材料に繋ぐ作業が必要である。
しかし、上述した離型シート付き帯状ゴムシート材料は、離型シートと帯状ゴムシート材料との２つをそれぞれ接続しなければならないため、繋ぎ合わせを自動化することが困難で、人手に頼らざるを得ないという問題があった。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、離型シートが付いた帯状ゴムシート材料相互を自動的に接続することが可能な帯状ゴムシート材料接続装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成する本発明は、離型シートを上側にして搬送される離型シート付き帯状ゴムシート材料の後端部に、巻き取りロールから離型シートを上側にして引き出された離型シート付き帯状ゴムシート材料の先端部を接続する帯状ゴムシート材料接続装置であって、前記離型シート付き帯状ゴムシート材料の搬送方向と直交する方向に移動可能な移動手段を設け、この移動手段に立設された支持部材に、前記離型シート付き帯状ゴムシート材料を巻き取った巻き取りロールをそれぞれ回転自在に支持する複数のロール支持部を有するロール支持手段と、このロール支持手段のロール支持部に支持された各ロールから引き出された離型シート付き帯状ゴムシート材料の先端部をそれぞれ載置する複数の先端載置部を有する先端載置手段とを設け、この先端載置手段の離型シート付き帯状ゴムシート材料搬送方向に隣接して、離型シート付き帯状ゴムシート材料を搬送する搬送路を有する搬送手段を設けると共に、前記先端載置手段の近傍に、搬送される離型シート付き帯状ゴムシート材料の後端を検出し、その後端位置を設定された所定の場所に位置決めする後端位置検出手段を配置し、前記先端載置手段と前記搬送手段との間に、搬送が停止された離型シート付き帯状ゴムシート材料の後端部を上方に持ち上げ可能なリフト手段を設け、前記先端載置手段の上方に離型シート付き帯状ゴムシート材料を押圧して接合する押圧接合手段を昇降、かつ離型シート付き帯状ゴムシート材料の搬送方向に沿って往復移動可能に配設し、前記先端載置手段の先端載置部が、離型シート先端部を剥離した帯状ゴムシート材料の先端部を載置する帯状ゴムシート材料載置部と、剥離された前記離型シート先端部を載置する離型シート載置部とを有し、該離型シート載置部が前記押圧接合手段の押圧作動時に離型シートの載置を解除する構成であることを特徴とする。
【０００６】
【作用】
本発明は上記のように構成され、後端位置検出手段により、離型シートを上側にして搬送される離型シート付き帯状ゴムシート材料の後端が検出されて、その後端位置が設定された所定の場所に位置決めされると、リフト手段により、搬送が停止された離型シート付き帯状ゴムシート材料の後端部が上方に持ち上げられ、続いて、移動手段の移動により、この移動手段に立設された支持部材に取付けられたロール支持手段と先端載置手段とが離型シート付き帯状ゴムシート材料の搬送方向と直交する方向に移動され、次のロールから引き出された離型シート付き帯状ゴムシート材料の先端部を載置した先端載置部が、押圧接合手段の下方にくる。リフト手段の降下動作により、上方に持ち上げられた接続される離型シート付き帯状ゴムシート材料の後端部が、接続する先端載置部の帯状ゴムシート材料載置部に載置された離型シート先端部を剥離した帯状ゴムシート材料の先端部上に重ねた状態で載置される。押圧接合手段が降下し、離型シートが付いた帯状ゴムシート材料の先端位置から搬送側に重ねられた前後の離型シート付き帯状ゴムシート材料の後端部と先端部とを押圧して接合を開始する。押圧接合手段が搬送方向側に向けて押圧しながら移動し、その後端部と先端部とを順次押圧して接合する。離型シート載置部は押圧接合手段が押圧作動した際に、離型シートの載置を解除するため、離型シートを上側にして搬送される離型シート付き帯状ゴムシート材料の後端部に、巻き取りロールから離型シートを上側にして引き出された離型シート付き帯状ゴムシート材料の先端部が人手を介することなく自動的に接続される。
【０００７】

【００１１】
上記先端載置手段６０は、支柱３１の上端に搬送方向Ａ側に向けて水平に突設された支持フレーム６１の搬送方向先端側に、各ロールＲから引き出された離型シート付き帯状ゴムシート材料Ｓの先端部をそれぞれ載置する、搬送方向Ａと直交する方向に配列された複数の先端載置部６３を有し、各先端載置部６３は、離型シート先端部ｍ₁を剥離した帯状ゴムシート材料ｎの先端部ｎ₁を載置する帯状ゴムシート材料載置部７０と、剥離された離型シート先端部ｍ₁を載置する離型シート載置部８０とを有するように構成されている。
【００１２】
各帯状ゴムシート材料載置部７０は、図３，４にその詳細を示すように、支持フレーム６１上に支持部片６５を介して水平に固設された共通の載置プレート７１上の先端側（搬送方向側）に、帯状ゴムシート材料ｎの先端部ｎ₁を載せる各載置部７２を有し、この載置部７２の搬送後方に隣接した載置プレート７１上には、ロールＲから引き出された離型シート付き帯状ゴムシート材料Ｓを載置部７２にガイドする左右一対のガイド部材７３を両側に設けた搬送路７４がそれぞれ配設されている。
【００１３】
また、載置プレート７１には、それぞれ３箇所（複数）に上下に貫通する長孔状の貫通孔７５，７６，７７が設けられている。貫通孔７５，７６が搬送路７４に、それを横断する方向で、かつ搬送方向Ａに所定の間隔を置いて２箇所に配置され、貫通孔７７が載置部７２の搬送側に搬送方向Ａに沿って延長するように形成されている。
【００１４】
前記左右一対のガイド部材７３がこの貫通孔７５，７６を介して載置プレート７１に着脱自在に固定され、ガイド部材７３を貫通孔７５，７６に沿って横断する方向に移動することにより、搬送路７４の幅を調整できるようになっている。また、貫通孔７６，７７は、後述する検出器用に使用される。
【００１５】
各離型シート載置部８０は、載置部７２搬送側で搬送左（一方）側に隣接した載置プレート７１上に垂直で回転自在に立設された各回転軸８１に、水平に横設された離型シート先端部ｍ₁を載置する載置バー８２をそれぞれ有している。回転軸８１は、図示せぬスプリング等の付勢部材により常時付勢され、載置バー８２を載置部７２上方に搬送方向Ａと直交して横切る方向にして、回転軸８１の載置部７２側に隣設されたストッパー部材８３に搬送側から当接するようにしている。
【００１６】
上記搬送手段９０は、ベースＢに垂直に立設された支柱２に水平方向に固設された搬送用プレート９１を有し、この搬送用プレート９１は、先端載置手段６０の載置プレート７１搬送側先端に所定の間隔を隔てて隣設されると共に、載置プレート７１とその上面（搬送面）が同じ高さになっている。
搬送用プレート９１上には、離型シート付き帯状ゴムシート材料Ｓの搬送をガイドする左右一対のガイド部材９２が両側に設けられ、このガイド部材９２間には、離型シート付き帯状ゴムシート材料Ｓを搬送する搬送路９３が形成されている。この搬送路９３の搬送側には、離型シート付き帯状ゴムシート材料Ｓを搬送するための搬送用ロール９４を有する搬送駆動手段９５（図５）が設置され、この搬送用ロール９４の回転駆動により、ロールＲから人手により搬送用ロール位置まで引き出された離型シート付き帯状ゴムシート材料Ｓに搬送を付与するようになっている。
【００１７】

【００１８】
検出器１０２ａ，１０２ｂは、上下一対の支持バー１０１ａ，１０１ｂの２箇所に所定の間隔置いてそれぞれ配置されると共に、上述した貫通孔７６，７７を介して対向するようになっている。検出器１０２ａ，１０２ｂは、図示せぬ制御装置を介して、搬送側の検出器が離型シート付き帯状ゴムシート材料Ｓの後端を検出すると、搬送手段９０の搬送を停止する構成である。
【００１９】
上記リフト手段１２０は、載置プレート７１と搬送用プレート９１との間に配置されたリフト用プレート１２１を備え、このリフト用プレート１２１は、搬送用プレート９１の搬送後端にヒンジ部材１２２を介して上下に揺動可能に取付けられている。
また、搬送用プレート９１の下面に固設された支持部片１２３にブラケット１２４を介して駆動用シリンダ（駆動手段）１２５が取付けられ、この駆動用シリンダの上方に突出して上下に伸縮するロッド１２６の上端が、ブラケット１２７を介して、リフト用プレート１２１の下端に連結されている。駆動用シリンダ１２５のロッド１２６が伸長すると、リフト用プレート１２１は先端側（搬送側）のヒンジ部材１２２を中心（支点）に上方に３０度前後旋回移動した上方位置となり、ロッド１２６が縮小すると、リフト用プレート１２１の上面は、載置プレート７１及び搬送用プレート９１の上面と同一高さの水平位置となるように構成されている。
【００２０】
上記押圧接合手段１５０は、搬送方向に沿って、かつ水平方向に往復移動可能な水平往復手段１６０と、この水平往復手段１６０に取付けられ垂直に昇降可能な昇降手段１７０と、この昇降手段１７０に装着され離型シート付き帯状ゴムシート材料Ｓの接続部（接合される先端部と後端部）を押圧して接合するための押圧ロール１８０（押圧手段）とを有した構成になっている。
【００２１】
水平往復手段１６０は、横設部材３の側部に水平方向に延設されたガイド部材１５１に沿って、搬送方向に往復移動自在な移動部材１６１を有し、この移動部材１６１の搬送側には、横設部材３の側部に固設された駆動用シリンダ（駆動手段）１６２の横方向に伸縮するロッド１６３の先端が連結され、この駆動用シリンダ１６２の作動により移動部材１６１がガイド部材１５１に沿って移動するようになっている。
【００２２】
昇降手段１７０は、移動部材１６１に取付けられた駆動用シリンダ（駆動手段）１７１を有し、この駆動用シリンダ１７１の下方に突出して上下に伸縮するロッド１７２の下端には、押圧ロール１８０を支持するための支持板１７３が固定されている。１７４は、ロッド１７２の両側で、支持板１７３に下端が固定された一対のガイドロッドである。
【００２３】
押圧ロール１８０は、支持板１７３の搬送方向両側に下向きで突設された一対のブラケット１８１の下部に横設され、回転自在に支持されている。この押圧ロール１８０は、離型シート付き帯状ゴムシート材料Ｓの幅よりも若干広いロール幅を有している。また、ブラケット１８１の下部には、押圧ロール１８０よりも搬送方向に突出する突部１９０ａを有する載置バー押し部材１９０が配設され、この載置バー押し部材１９０は、押圧ロール１８０が降下して、接合する離型シート付き帯状ゴムシート材料を押圧し、水平往復手段１６０の作動により、搬送方向Ａ側に移動した際に、その突部１９０ａの先端が離型シート載置部８０の載置バー８２を押し退けて、離型シートｍの先端部ｍ₁の載置を解除するようになっている。
【００２４】
また、５は支持フレーム６１上の搬送後端側にそれぞれ（各ロールＲに対応して）配置された回転自在な離型シート付き帯状ゴムシート材料Ｓのガイドロール、６は下段のロール支持部４１に支持されたロールＲの離型シート付き帯状ゴムシート材料Ｓをガイドロール５へガイドするための回転自在な下段用ガイドロールである。
【００２５】
以下、上述した構成の装置の作用について説明する。
先ず、図２に２点鎖線で示すように、各ロール支持部４１のロール支持軸４５に、離型シート付き帯状ゴムシート材料Ｓを巻き取った巻き取りロールＲをセットする。この時、押圧接合手段１５０の押圧ロール１８０の下方には、一端側の先端載置部６３が位置している。
【００２６】
次いで、押圧ロール１８０の下方に位置するロールＲから離型シート付き帯状ゴムシート材料Ｓをガイドロール６，５を介し、載置プレート７１の載置部７２、水平状態のリフト用プレート１２１、搬送用プレート９１の搬送路９３を経て、搬送手段９０の搬送用ロール９４まで人手により引き出す。
続いて、他の各ロールＲから離型シート付き帯状ゴムシート材料Ｓをガイドロール６，５を介して引き出し、その先端部を帯状ゴムシート材料ｎから離型シートｍを離型し、帯状ゴムシート材料先端部ｎ₁を載置プレート７１の載置部７２にその先端が貫通孔７７を搬送側に越えた状態で載置し、離型シート先端部ｍ₁を離型シート載置部８０の載置バー８２上に載置する。離型シート先端部ｍ₁には、接着テープｔ（図５（ｃ））が貼着される。
【００２７】
載置終了後、装置を作動させる。搬送用ロール９４の回転駆動により、押圧ロール１８０の下方に位置するロールＲから離型シートｍを上側にした離型シート付き帯状ゴムシート材料Ｓが、図５（ａ）のように搬出され、その後端が後端位置検出手段１００の２箇所に設けられた検出器１０２ａ，１０２ｂにより順次、検出される。
【００２８】
貫通孔７７を介して対向する搬送側の検出器が離型シート付き帯状ゴムシート材料Ｓの後端を検出すると、搬送用ロール９４の駆動が停止される。搬送される離型シート付き帯状ゴムシート材料Ｓの後端位置が設定された所定の場所に位置決めされ、その後端部Ｓ１が載置部７２上の搬送側に載置された状態となる（図５（ｂ））。
【００２９】
続いて、リフト手段１２０の駆動用シリンダ１２５が作動し、ロッド１２６が上方に伸長する。リフト用プレート１２１がヒンジ部材１２２を中心に上方に旋回し、離型シート付き帯状ゴムシート材料Ｓの後端部Ｓ１を上方に持ち上げる。移動手段１０の駆動モータ１７の作動により、プーリー１７ａ、ベルト１９、プーリー１５を介して、ボールネジ１３が一方向に回転し、移動体本体１１がガイドレール１に沿ってそのレール上を移動し、隣の先端載置部６３を押圧接合手段１５０の押圧ロール１８０の下方にする（図５（ｃ））。
【００３０】
リフト手段１２０の駆動用シリンダ１２５が作動し、ロッド１２６が下方に縮小し、リフト用プレート１２１が下方に旋回してその上面を載置プレート７１及び搬送用プレート９１の上面と同一高さとする水平位置になる。この時、接続される（被接続側）離型シート付き帯状ゴムシート材料Ｓの後端部Ｓ１は、接続する（接続側）帯状ゴムシート材料先端部ｎ₁の上に載置され、重ね合わされた状態となる。
【００３１】
次いで、押圧接合手段１５０が作動する。昇降手段１７０の駆動用シリンダ１７１が作動し、ロッド１７２が下方に向けて伸長し、押圧ロール１８０が接続される離型シートｍが付いている部分の離型シート付き帯状ゴムシート材料先端部と当接して押圧する押圧位置まで降下する（図５（ｄ））と、水平往復手段１６０の駆動用シリンダ１６２の伸長していたロッド１６３が縮小し、移動部材１６１の移動を介して、押圧ロール１８０が搬送側の離型シート付き帯状ゴムシート材料Ｓの接続する後端部Ｓ１側に向けて移動する。
【００３２】
この時、押圧ロール１８０の押圧に先立って、その押圧ロール１８０よりも搬送側に突出した載置バー押し部材１９０が離型シート載置部８０の離型シート先端部ｍ₁を載置した載置バー８２と当接して押す。載置バー８２は、回転軸８１を中心に次第に旋回して搬送経路の外側に押し退けられるため、載置バー８２に載置された離型シート先端部ｍ₁は、搬送側の接続する離型シート付き帯状ゴムシート材料Ｓの後端部Ｓ１上に重なり、移動する押圧ロール１８０により、接続部相互が図５（ｅ）のように押圧されて接続される。
【００３３】
押圧ロール１８０の押圧により重ね合わされた帯状ゴムシート材料相互は接続され、また、接着テープｔを介して、重ね合わされた離型シート相互も確実に接続され、従って、離型シートを上側にして搬送される離型シート付き帯状ゴムシート材料の後端部に、巻き取りロールＲから離型シートを上側にして引き出された離型シート付き帯状ゴムシート材料の先端部の自動接続が可能になる。
【００３４】
接続が終了すると、昇降手段１７０の駆動用シリンダ１７１が作動し、ロッド１７２が上方に向けて縮小し、所定の高さまで押圧ロール１８０が上昇すると、続いて、水平往復手段１６０の駆動用シリンダ１６２のロッド１６３が伸長し、移動部材１６１の移動を介して、押圧ロール１８０が図２に実線で示す位置まで移動し、次の接続時までそこに待機する。
【００３５】
また、押圧ロール１８０が上昇を開始すると、搬送手段９０の搬送用ロール９４が回転駆動され、被接続側の離型シート付き帯状ゴムシート材料と共に、接続側の離型シート付き帯状ゴムシート材料がロールＲから搬出される。
接続側の離型シート付き帯状ゴムシート材料がロールＲから完全に搬出され、その後端が後端位置検出手段１００の上記検出器１０２ａ，１０２ｂにより検出されると、再び、上述した作動を装置は繰り返し、更に隣の先端載置部６３に載置された次のロールＲから引き出された離型シート付き帯状ゴムシート材料の先端部を、搬出された離型シート付き帯状ゴムシート材料の後端部に接続するのである。
【００３６】
搬出が終えて空になったロールは、作業者により、離型シート付き帯状ゴムシート材料を巻き取ったロールと交換され、その先端部が載置プレート７１の載置部７２と離型シート載置部８０の載置バー８２上に載置される。移動手段１０の移動体本体１１が一端側まで移動し、他端側の先端載置部６３に載置された離型シート付き帯状ゴムシート材料の先端部が接続されて、搬出されると、移動体本体１１は図２の実線に示す他端側の位置まで戻り、上述した先端載置部６３に載置された離型シート付き帯状ゴムシート材料の先端部の接続操作が繰り返される。従って、離型シートを上側にして搬送される離型シート付き帯状ゴムシート材料の後端部に、巻き取りロールから離型シートを上側にして引き出された離型シート付き帯状ゴムシート材料の先端部が順次、自動的に接続される。
【００３７】
