Description

【０００１】
【発明の属する技術分野】
この発明は、例えば、古紙、古着、或いは、シート、袋等の物品を結束する線状、帯状、紐状の結束体を切除する作業に用いられるような結束体切除装置に関する。
【０００２】
【従来の技術】
従来、上述例のような結束体を切除する装置としては、図２０に示すように、例えば、古紙をプレスしてなるベール等のような物品Ａを結束する多数本（例えば、５本）の番線Ｃ…と直交する方向であって、物品Ａの両側面に対向して鋸歯状の切断刃１００，１００を配設し、両側上部に配設した進退用シリンダ１０１，１０１のロッド端部に昇降用シリンダ１０２，１０２を垂直固定し、その切断用シリンダ１０２，１０２のロッド端部を切断刃１００，１００の上端部に固定している。
【０００３】
切断時に於いて、進退用シリンダ１０１，１０１を作動して、物品Ａの両側面に対して切断刃１００，１００を押圧した後、昇降用シリンダ１０２，１０２を作動して、物品Ａの外面に巻回された番線Ｃ…に対して直交する上下方向に切断刃１００，１００を往復移動させ、物品Ａの外面に巻回された番線Ｃ…を切断刃１００，１００により一括して切断するものである。
【０００４】
【発明が解決しようとする課題】
しかし、上述のように古紙等をプレスしてなる物品Ａを番線Ｃ…により結束する場合、荷崩れを防止するために、物品Ａの外面に対して番線Ｃ…を食込ませた状態に巻回するので、物品Ａの外面よりも内側に番線Ｃ…が没入していると、切断時に於いて、物品Ａの外面に対して切断刃１００が当接され、番線Ｃ…に対する切断刃１００が当接が妨げられるため、切断量が浅くなったり、切断ミスが起きたりすることがある。物品Ａを結束する番線Ｃ…に切断刃１００を当接したとき、その当接力により番線Ｃ…が上下方向に若干移動し、その巻回位置が変位するため、番線Ｃ…を正確且つ確実に切断することが困難であるという問題点を有している。
【０００５】
また、物品Ａを結束する番線Ｃ…の一端を切断すると同時に、番線Ｃ…の結束が解かれ、物品Ａの下方に番線Ｃ…が自重落下するので、番線Ｃ…の両端を同時に切断することができない。且つ、切断刃１００により切断された番線Ｃ…が周囲に散乱するため、その番線Ｃ…を作業者の手で回収しなければならず、回収作業に手間及び時間が掛かるという問題点も有している。
【０００６】
この発明は上記問題に鑑み、物品を結束する結束体の一端を切断手段により切断し、結束体の他端を牽引手段により牽引して、牽引手段により牽引した結束体を巻回手段により巻回するので、結束体の切断作業及び回収作業が機械的に行え、作業の省力化及び能率アップを図ることができる結束体切除装置の提供を目的とする。
【０００７】
【課題を解決するための手段】
請求項１記載の発明は、物品を結束する結束体を切除する結束体切除装置であって、上記物品の側部に、該物品の外面に巻回された結束体の一端を切断する切断手段と、該物品の外面に対して離間される方向に結束体の他端を牽引する牽引手段とを設け、上記結束体の牽引側端部と対向して、上記牽引手段により牽引された結束体を巻回する巻回手段を設け、上記巻回手段を、上記牽引手段により牽引された結束体の牽引側端部を保持して該結束体が巻取られる方向に回転する巻取り部と、上記巻取り部に対して結束体の牽引側端部を供給する供給手段で構成し、上記巻取り部に、上記結束体の端部を挾持する一対の巻取り部材を相対向して設けると共に、該巻取り部材を結束体の端部が挾持される方向に対して移動可能に設けた結束体切除装置であることを特徴とする。
【０００８】
請求項２記載の発明は、上記請求項１記載の発明の構成と併せて、上記牽引手段を、上記結束体の牽引側端部と対向する方向に対して一対の牽引部材を移動可能に設け、上記牽引部材の先端部に、上記結束体の牽引側端部に対して係止される係止突起を形成し、該係止突起の間に結束体を係止する係止溝を形成すると共に、上記一対の牽引部材を係止突起及び係止溝が交差される方向に対して相対移動可能に設けて構成した結束体切除装置であることを特徴とする。
【０００９】
【作用】
請求項１記載の結束体切除装置は、物品を結束する結束体の一端を切断手段により切断するとき、その結束体の他端を牽引手段により保持する。切断手段により結束体を切断した後、牽引手段により保持した結束体の他端を任意長さ牽引する。牽引手段により牽引された結束体の牽引側端部を、巻回手段の巻取り部に設けた一対の巻取り部材間に対して供給手段により供給する。一対の巻取り部材により結束体の端部を挾持した後、牽引手段による結束体の保持を解除して、例えば作業者の手等の人為的手段又はモータ等の機械的手段により巻取り部を巻取り方向に回転させ、巻取り部の外面に対して結束体を巻回（例えば、渦巻状又は螺旋状）するので、巻回時に於いて、結束体が抜け落ちるのを確実に防止することができ、結束体の巻回作業が確実且つ容易に行える。且つ、任意の線径又は横幅に形成された結束体を巻回する作業に適用できる。また、結束体を切断する作業が正確且つ確実に行える。同時に、切断された結束体が周囲に散乱するのを防止でき、その結束体を回収する作業及び時間が省ける。
【００１０】
請求項２記載の結束体切除装置は、上記請求項１記載の作用と併せて、一対の牽引部材に形成した係止突起を物品の外面に食込み又は突刺した後、相互を垂直方向又は水平方向に相対移動させ、係止突起の間に形成した係止溝内に結束体を導くと共に、一対の牽引部材に形成した係止突起及び係止溝を互い違いとなる状態に交差して結束体を挾持するので、物品の外面よりも内側に結束体が没入又は食込んでいても確実に保持することができる。牽引時に於いて、結束体が落下するのを確実に防止することができ、物品の外面から結束体を分離及び牽引する作業が確実に行える。
【００１１】
【発明の効果】
この発明によれば、結束体の一端を切断手段により切断するとき、その結束体の他端を牽引手段により保持するので、切断時に於いて、結束体が上下動したり、巻回位置が変位したりするのを防止でき、結束体を切断する作業が正確且つ確実に行える。しかも、牽引手段により保持した結束体を牽引し、その牽引された結束体を巻回手段により巻回するので、従来例のように切断された結束体が周囲に散乱するのを防止することができ、その結束体を回収する作業及び時間が省けると共に、結束体の切断作業及び回収作業が機械的に行え、作業の省力化及び能率アップを図ることができる。且つ、結束体を渦巻状又は螺旋状に巻回することで、回収時に於いて、結束体を折曲げたり、一つに束ねたりする必要が無く、結束体をストックするためのスペースが小さくて済み、結束体の回収及びその取扱いが容易に行える。
【００１２】
さらに、一対の牽引部材に形成した係止突起を物品の外面に食込み又は突刺した後、係止突起及び係止溝を互い違いとなる状態に交差して、係止突起の間に形成した係止溝に結束体を導いて挾持するので、物品の外面よりも内側に結束体が没入又は食込んでいても確実に保持することができる。牽引時に於いて、結束体が落下するのを確実に防止することができ、切断済みの結束体を一括して分離及び牽引する作業が確実に行える。
【００１３】
さらにまた、人為的手段又は機械的手段により巻取り部を巻取り方向に回転して結束体を巻回するので、巻取り部の外面に対して、例えば、渦巻状、螺旋状等に結束体を巻回することができ、結束体の巻回作業が容易に行える。且つ、一対の巻取り部材を任意方向に移動して結束体の端部を挾持することで、巻回時に於いて、結束体が抜け落ちるのを確実に防止することができ、結束体の巻回作業が確実に行えると共に、任意の線径又は横幅に形成された結束体を巻回する作業に適用できる。
【００１４】
【実施例】
この発明の一実施例を以下図面に基づいて詳述する。
図面は物品を結束する多数本の結束体を切除及び回収する作業に用いられる結束体切除装置を示し、図１、図２、図３に於いて、この結束体切除装置１は、例えば、番線、バンド等の結束体Ｂ…により結束された物品Ａ（例えば、古紙をプレスしてなるベール等）を搬入する搬入装置２と、結束体Ｂが切除された物品Ａを搬出する搬出装置３との間に配設され、装置２，３の間に配設した搬送装置４上の切断位置ａに物品Ａが搬送されたとき、その物品Ａの外面に巻回された結束体Ｂ…を一括して切除する。切除後に於いて、結束体Ｂが切除された物品Ａをガイド部材５を介して搬出装置３に移載し、次工程（図示省略）に搬送する。
【００１５】
上述した物品Ａは、図１５に示すように、例えば、古紙、古着等を圧縮又は積層して六面体となる形状に形成され、その物品Ａの外面に、例えば、金属、合成樹脂、繊維等の適宜材質により線状又は帯状、紐状に形成された多数本の結束体Ｂ…を所定間隔に隔てて横方向に巻回して結束固定している。なお、実施例では、金属製の番線又はバンド等で構成される結束体Ｂを結束している。
【００１６】
前述した結束体切除装置１は、基台７の上面側中央部に取付け枠８を送り方向（矢印方向）に対して直交して水平に架設し、取付け枠９を送り方向に対して直交して鉛直に立設し、基台７の中央部に、搬入装置２から搬出装置３に向けて物品Ａを搬送するための搬送装置４を配設し、その搬送装置４の搬出側に、搬出装置３に向けて物品Ａの移載をガイドするためのガイド部材５を斜設している。
【００１７】
前述した搬送装置４は、図１１にも示すように、搬出側に軸支したロール１１と、搬入側に軸支したロール１２との間に搬送ベルト１３を張架し、ロール１１，１２の間に配列した支持ローラ１４…により搬送ベルト１３の搬送側全長を水平状態に支持し、搬出側下部に配設した減速機付き送り用モータ１５の駆動力により、スプロケット１６，１７及び駆動チェーン１８を介して、搬送ベルト１３を送り方向（矢印方向）に回転させ、その搬送ベルト１３上に載置された物品Ａを送り方向に搬送し、結束体Ｂにより結束された物品Ａを切断位置ａに一旦停止させる。
【００１８】
前述した搬入装置２上には、結束体Ｂにより結束された物品Ａを中央部搬送面にセンタリングするためのセンタリング装置１９を設けている。センタリング装置１９は、図４にも示すように、搬入装置２の両側部に対して基軸２０，２１を鉛直方向に軸受し、基軸２０の上下端に固定したアーム２２，２２及び基軸２１の上下端に固定したアーム２３，２３の基端側に支持ロッド２４を夫々架設し、アーム２２，２２及び２３，２３の遊端側にセンタリング用の修正ローラ２５を夫々軸架している。且つ、基軸２０，２１の上端側を、リンク２６，２６及び連結ロッド２７を介して連結し、装置上部に取付けた旋回用シリンダ３０のロッドを、リンク２８を介して基軸２０の上端部に連結している。旋回用シリンダ３０の作動により、基軸２０，２１を支点として修正ローラ２５，２５を矢印方向に旋回させ、搬入装置２により搬送される物品Ａの両側面に修正ローラ２５，２５を均等に押圧して、搬入装置２の搬送中心に対して物品Ａが載置される位置及び姿勢にセンタリングする。
【００１９】
一方、図２、図３に於いて、切断位置ａの両側部には、後述する切断ユニット３１を移動するための移動機構３３を左側に配設し、牽引ユニット３２を移動するための移動機構３４を右側に配設している。機構３３，３４は、連動又は独立して駆動され、送り方向に対して直交する方向（左右方向）に切断ユニット３１と牽引ユニット３２とを相対移動する。
【００２０】
上述した移動機構３３は、取付け枠８の左側上面に対して可動台３５を左右移動可能に架設し、可動台３５上に配設した移動用シリンダ３６のロッドを取付け枠８の左側端部に連結して、移動用シリンダ３６の作動により、切断位置ａに搬送された物品Ａの左側面に対して後述する可動刃４９及び固定刃５３が押圧される前進位置と、搬送装置４による物品Ａの搬送が許容される後退位置とに切断ユニット３１を進退移動する。
【００２１】
前述した移動機構３４は、取付け枠８の右側上面に対して可動台３７を左右移動可能に架設し、同枠下部に軸支したスプロケット３８ａ，３８ａ間にチェーン３８ｂを張架し、移動用チェーン３８ｂの端部を可動台３７の下面側に連結して、内側下部に配設した減速機付き移動用モータ３９の駆動力により、スプロケット３９ａ，３９ｂ及び駆動チェーン３９ｃを介して、チェーン３８ｂを正逆回転させ、切断位置ａに搬送された物品Ａの右側面に対して後述する可動板５５及び固定板５６が押圧される前進位置と、搬送装置４による物品Ａの搬送及び後述する巻回機構７４の動作が許容される後退位置とに牽引ユニット３２を進退移動する。
【００２２】
上述した切断ユニット３１及び牽引ユニット３２は、後述する可動刃４９及び固定刃５３と、可動板５５及び固定板５６の説明を除いてその他の部分が同一構成であるので、その同一部分の構成を図面に基づいて詳述する。可動台３５，３７の前端側上面部に、軸受４０，４０を介して支軸４１を夫々軸架し、支軸４１の軸周面に可動枠４２の下端部を傾動可能に枢着すると共に、可動枠４２の後面側上端部と、可動台３５，３７の後端側上面部に立設した取付け枠４３との間に、傾動用シリンダ４４の作動により、物品Ａの側面形状に対応して可動枠４２を傾動し、例えば、スラント状に傾斜したような物品Ａの側面形状にも対応できるように設けている。
【００２３】
可動枠４２に対するユニット３１，３２の取付け構造は略対称であるので、後述する可動刃４９及び固定刃５３と、可動板５５及び固定板５６の説明を除いて同一部分の構造を図面に基づいて詳述する。図５、図６に示すように、可動枠４２の物品Ａと対向する側の面にブラケット４５を介してレール４６を上下方向に架設し、このレール４６上に複数のスライダ４７…を介して可動部材４８を上下動可能に係合し、この可動部材４８に、切断ユニット３１の可動刃４９と牽引ユニット３２の可動板５５とを一体的に固定している。
【００２４】
且つ、可動枠４２に固定した複数のブロック５０に、例えば、ボルト及びナット等で構成される調節機構５１を介して固定部材５２を固定し、その固定部材５２に切断ユニット３１の固定刃５３と牽引ユニット３２の固定板５６とを一体的に固定している。その調節機構５１の操作により、切断ユニット３１の可動刃４９と固定刃５３との対接隙間を、例えば、約０．２〜約０．５mm程度に可変調節し、牽引ユニット３２の可動板５５と固定板５６との対接隙間を任意間隔に可変調節する。可動枠４２の上端側平面部に配設した可動用シリンダ５４のロッドを可動部材４８の上端部に連結し、可動用シリンダ５４の作動により、切断ユニット３１の可動刃４９を固定刃５３に対接した状態のまま上下方向に往復移動（例えば、約２山〜約３山）し、牽引ユニット３２の可動板５５を固定板５６に対接した状態のまま上下方向に往復移動する。
【００２５】
且つ、図７に示すように、可動刃４９及び固定刃５３の刃部４９ａ，５３ａを、例えば、鋸歯状、櫛歯状等に形成すると共に、刃部４９ａ，５３ａを上下逆向きに交差される向き及び角度に形成している。刃部４９ａ，５３ａの先端部に、溝部４９ｂ，５３ｂに対して結束体Ｂが導かれる形状に傾斜又は湾曲してなるガイド部４９ｃ，５３ｃを形成している。
【００２６】
一方、図８、図９に示すように、可動板５５及び固定板５６の係止爪５５ａ，５６ａを、例えば、楔形状、鉤形状等の先細又は尖鋭となる形状であって、結束体Ｂ…に対して係止される形状に形成すると共に、係止爪５５ａ…及び係止爪５６ａ…の先端部を、係止溝５５ｂ，５６ｂに対して結束体Ｂ…が導かれる方向に向けて幅狭となる形状に形成し、係止爪５５ａ…及び係止爪５６ａ…の間と対応する係止溝５５ｂ，５６ｂの一部を結束体Ｂの挿入が許容される間隔に切欠き形成している。
【００２７】
また、ブロック５０，５０の間に物品Ａの側面と対向して当接部材５８を進退移動可能に設けている。この当接部材５８は、可動枠４２に固定した軸受部５８ａに対して進退移動可能に軸受され、軸受部５８ａとストッパ５８ｂとの間に圧縮装填したコイルスプリング５８ｃの弾性により突出方向に付勢している。つまり、ユニット３１，３２を前進動作（物品Ａと対向する方向）したとき物品Ａの側面に当接部材５８が当接され、その当接時の移動をセンサ等の検知手段（図示せず）により検知して移動機構３３，３４の駆動を停止制御するものである。
【００２８】
一方、図１、図３に示すように、取付け枠９の上端側中央部に、搬送装置４と同期して物品Ａを送り方向に移動するための移動機構６０を配設している。移動機構６０は、取付け枠９の搬出側枠部９ａ，９ａに沿って鉛直に軸架したネジ軸６２，６３と、枠部９ａ，９ａに沿って架設したレール６８，６９とに昇降枠７０の両端部を上下動可能に取付け、一方の枠部９ａ側に取付けた減速機付き昇降用モータ６４の駆動力により、スプロケット６５，６６及び連動チェーン６７を介して、ネジ軸６２，６３を正逆回転させ、切断位置ａに搬送される物品Ａの高さに対応して昇降枠７０を上下動する。
【００２９】
且つ、図１０に示すように、昇降枠７０の下面側中間部に取付け枠７１を送り方向に平行して架設し、取付け枠７１の下面側全長にロッドレス型の移動用シリンダ６１を水平固定し、取付け枠７１の長手側中央部に、切断位置ａに搬送される物品Ａの上面と対向して当接部材７２を上下移動可能に設けている。この当接部材７２は、昇降枠７０の側部に固定した軸受部７２ａに対して上下移動可能に軸受され、軸受部７２ａとストッパ７２ｂとの間に圧縮装填したコイルスプリング７２ｃの弾性により垂直方向に付勢している。つまり、昇降枠７０を下降動作したとき物品Ａの上面に当接部材７２が当接され、その当接時の移動をセンサ等の検知手段（図示省略）により検知して昇降用モータ６４の駆動を停止制御するものである。
【００３０】
且つ、図１１に示すように、移動用シリンダ６１の下面側に支持部材７３を取付け、移動用シリンダ６１の作動により支持部材７３を送り方向に平行して前後移動する。つまり、切断前に於いて、物品Ａの後面側に支持部材７３を当接し、物品Ａが倒れるのを防止する。切断後に於いて、物品Ａの後面側に支持部材７３を当接した状態のまま移動すると共に、搬送装置４と同期して物品Ａを搬出装置３に対して移載される方向に移動する。
【００３１】
一方、切断位置ａの右側部には、牽引ユニット３２により牽引された結束体Ｂ…を巻取るための巻回機構７４を配設している。巻回機構７４は、図１２にも示すように、取付け枠９の右側上部に架設した取付け枠７５の下面側に、牽引された結束体Ｂ…に対して直交する方向に可動枠７６を前後移動可能に架設し、可動枠７６の下面側前端部に、結束体Ｂ…の牽引側端部に対して押圧される長さに形成した棒状又は板状の押込み部材７７を垂直に架設している。且つ、取付け枠７５の長手側両端部に軸支したスプロケット７８ａ，７８ｂ間にチェーン７８ｃを張架し、そのチェーン７８ｃの端部を可動枠７６の上面側に連結して、取付け枠７５上部に配設した減速機付き移動用モータ７９の駆動力により、スプロケット７９ａ，７９ｂ及び駆動チェーン７９ｃを介して、チェーン７８ｃを正逆回転させ、牽引ユニット３２による結束体Ｂ…の牽引動作が許容される後退位置（図中、実線で示す）と、後述する巻取り部材８０，８０の間に対して押込み部材７７が挿入される前進位置（図中、仮想線で示す）とに可動枠７６を往復移動する。なお、空気圧式又は油圧式シリンダ（図示省略）により可動枠７６を往復移動してもよい。
【００３２】
上述した巻取り部材８０，８０は、取付け枠９の搬入側右側部（図１に示す左側）に上述した押込み部材７７と対向して鉛直に立設している。巻取り部材８０，８０の上下端部に固定した受け板８１，８１を、上下に配設した軸受８２，８２により水平回転可能に軸受すると共に、巻取り部材８０，８０の間を、押込み部材７７の挿入動作が許容される間隔であって、結束体Ｂ…の牽引側端部が抜止めされる間隔に設定又は調節可能に設けている。
【００３３】
且つ、巻取り部材８０，８０の下端部に対して下側受け板８１を嵌合可能に設け、下側軸受８２に連結した揺動アーム８３の基端部を上下動可能に枢支すると共に、同側下部に配設した揺動用シリンダ８４のロッド端部を揺動アーム８３の基端部に連結して、揺動用シリンダ８４の作動により、巻取り部材８０，８０の下端部に対して嵌合固定される閉位置と、巻取り部材８０，８０により巻取られた結束体Ｂ…の落下が許容される開位置とに下側受け板８１を上下揺動する。なお、巻取り部材８０，８０の下部には、渦巻状又は螺旋状に巻回された結束体Ｂ…を投入するための投入部８５を配設している。
【００３４】
且つ、取付け枠７５上部に配設した減速機付き回転用モータ８６を上側受け板８１に直結して、回転用モータ８６の駆動力により、押込み部材７７の挿入が許容される向き及び角度に巻取り部材８０，８０を回転停止させ、巻回時に於いて、巻取り部材８０，８０を巻取り方向に対して適宜角度（例えば、約９０度）だけ初期回転させ、巻取り部材８０，８０の間に押込まれた結束体Ｂ…の端部を若干巻取る。続いて、適宜回数（例えば、約５回）だけ連続回転して、巻取り部材８０，８０の外面に対して結束体Ｂ…を渦巻状又は螺旋状に巻回する。更に、切断位置ａの右側部であって、巻回機構７４の直前に、牽引ユニット３２の牽引動作が許容される間隔に隔てて複数本のガイドローラ８７…を鉛直に軸架し、牽引ユニット３２により牽引される結束体Ｂ…の両端部を幅寄せ方向に対して牽引ガイドする。なお、作業者の手で操作ハンドル（図示省略）を回転し、その回転力により減速機構（図示省略）を介して巻取り部材８０，８０を巻取り方向に回転駆動するもよく、上述と同様に、結束体Ｂ…を巻回することができる。
【００３５】
図１３は、結束体Ｂの押込み動作に対応して巻取り部材８０，８０を任意角度に回動する巻回機構７４の他の例を示し、巻取り部材８０の一端側中心部に突出された支軸８８の端部に可動アーム８８ａを水平固定し、同側に配設した移動用シリンダ８９を作動して、そのロッド端部に固定した当接板８９ａを、可動アーム８８ａの遊端部に枢着したカム８８ｂに当接し、巻取り部材８０を任意角度に水平回動する。つまり、巻取り部材８０，８０の間に結束体Ｂを押込むとき、押込み部材７７の挿入が許容される開角度に巻取り部材８０，８０を回動（図中、仮想線で示す）して、巻取り部材８０，８０の間に対して結束体Ｂ…を押込み部材７７により押込み、その間から押込み部材７７を引抜くと共に、結束体Ｂが抜止め又は挾持される閉角度に巻取り部材８０，８０を回動（図中、実線で示す）して保持するので、上述した実施例と同様に、結束体Ｂの巻取り作業が容易に行える。なお、巻取り部材８０，８０を、スプリング等の弾性部材（図示省略）の弾性により結束体Ｂを抜止めする回動姿勢に対して回動復帰される方向に回動付勢している。
【００３６】
図１４は、結束体Ｂを略円形に巻取りする巻回機構７４の他の例を示し、巻取り部材８０，８０の外側であって、受け板８１，８１の外周縁部よりも内側に、円弧状に形成したガイド板９０，９０を鉛直に架設し、そのガイド板９０，９０の外面に沿って結束体Ｂを略円形に巻取ると共に、受け板８１，８１の外周縁部に近接して軸支したガイドローラ９１，９１により、ガイド板９０，９０の外面に沿って結束体Ｂが巻き取られる状態に巻取りガイドするので、上述した実施例と同様に、結束体Ｂの巻取り作業が容易に行える。且つ、結束体Ｂ…を略同径及び同形状に巻取ることができ、回収及び取扱いが容易に行える。なお、その他の構成部分は、上述例と略同一構成であるのでその説明を省略する。
【００３７】
図示実施例は上記の如く構成するものにして、以下、結束体切除装置１により物品Ａを結束する結束体Ｂ…の切除動作を説明する。
先ず、多数本の結束体Ｂ…により結束された物品Ａが搬入装置２の終端側に搬送されたとき、図４に示すように、センタリング装置１９を駆動して、物品Ａの両側面に対して修正ローラ２５，２５を同時押圧し、搬入装置２の搬送中心に対して物品Ａが真っ直ぐに載置される位置及び姿勢にセンタリングする。センタリング後に於いて、修正ローラ２５，２５を初期位置に回動復帰する。
【００３８】
次に、センタリングされた物品Ａを搬入装置２から搬送装置４に移載し、搬送路上に設定した切断位置ａに物品Ａを搬送停止する。この後、図１０に示すように、移動機構６０を駆動して、物品Ａの上面側に対して当接部材７２が当接される高さ位置に昇降枠７０を垂直下降させ、物品Ａの上面側に当接部材７２を当接し、且つ、物品Ａの後面側に支持部材７３を当接して倒れ防止する。
【００３９】
次に、図１６に示すように、移動機構３３，３４を駆動して、物品Ａの両側面と対向する方向に切断ユニット３１と牽引ユニット３２とを移動させ、図７に示すように、切断ユニット３１の可動刃４９及び固定刃５３を物品Ａに巻回された結束体Ｂ…の間に突刺（例えば、約５mm程度）し、同時に、図８に示すように、牽引ユニット３２の可動板５５及び固定板５６を物品Ａに巻回された結束体Ｂ…の間に食込み又は突刺し、連通した可動板５５の係止溝５５ｂ…及び固定板５６の係止溝５６ｂ…に対して結束体Ｂ…を導く。
【００４０】

BACKGROUND OF THE INVENTION
The present invention relates to a bound body excision apparatus that is used, for example, for excising a linear, belt-like, or string-like bound body for binding articles such as used paper, used clothes, or sheets and bags.
[0002]
[Prior art]
Conventionally, as an apparatus for cutting a bundled body as in the above-described example, as shown in FIG. 20, for example, a large number (for example, five) of bundling articles A such as a bale formed by pressing waste paper Sawtooth-shaped cutting blades 100, 100 are disposed in the direction orthogonal to the number C, opposite to both side surfaces of the article A, and are attached to the rod ends of the forward and backward cylinders 101, 101 disposed on the upper sides. The elevating cylinders 102 and 102 are fixed vertically, and the rod ends of the cutting cylinders 102 and 102 are fixed to the upper ends of the cutting blades 100 and 100.
[0003]
At the time of cutting, the advancing and retreating cylinders 101 and 101 are operated to press the cutting blades 100 and 100 against both side surfaces of the article A, and then the lifting and lowering cylinders 102 and 102 are operated to move the cylinder A to the outer surface of the article A. The cutting blades 100, 100 are reciprocated in the vertical direction orthogonal to the wound wire C ..., and the wire C ... wound on the outer surface of the article A is cut together by the cutting blade 100, 100. It is.
[0004]
[Problems to be solved by the invention]
However, when the article A formed by pressing waste paper or the like as described above is bound by the number lines C ..., it is wound in a state where the number lines C ... are bitten into the outer surface of the article A in order to prevent the collapse of the load. When the wire C is immersed inside the outer surface of the article A, the cutting blade 100 is brought into contact with the outer surface of the article A at the time of cutting. Since contact | abutting is prevented, the amount of cutting | disconnection may become shallow and a cutting | disconnection mistake may occur. When the cutting blade 100 is brought into contact with the wire C that binds the article A, the wire C is slightly moved in the vertical direction by the contact force, and the winding position is displaced, so that the wire C is accurately and reliably disposed. There is a problem that it is difficult to cut.
[0005]
Further, at the same time that one end of the number wire C ... for binding the article A is cut, the number wire C ... is unbound and the number line C ... falls under the article A by its own weight, so both ends of the number wire C ... are cut simultaneously. I can't. Moreover, since the numbered lines C ... cut by the cutting blade 100 are scattered around, the numbered lines C ... must be collected by the operator's hand, and there is a problem that the collecting work takes time and effort. ing.
[0006]
In view of the above problems, the present invention cuts one end of a bundle that binds articles by cutting means, pulls the other end of the bundle by pulling means, and winds the bundle pulled by the pulling means by winding means. Therefore, an object of the present invention is to provide a bundle excision apparatus that can mechanically perform a cutting operation and a collection operation of a bundle, saving labor and improving efficiency.

And a traction means that pulls the other end of the bundle in a direction away from the outer surface of the article, and the bundle is pulled by the traction means opposite the pulling side end of the bundle. Winding means for winding The winding means holds the pulling side end of the binding body pulled by the pulling means and rotates in the direction in which the binding body is wound, and binds to the winding section. A supply means for supplying a pulling side end of the body, and a pair of winding members for holding the ends of the binding body are provided opposite to each other on the winding portion, and the winding member is attached to the binding body. Provided to be movable in the direction in which the end of It is a bundling body excision device.
[0008]
According to a second aspect of the present invention, in combination with the configuration of the first aspect of the present invention, the traction means is provided such that a pair of traction members are movable in a direction facing the traction side end of the bundle. A locking protrusion that locks against the pulling side end of the bundle is formed at the tip of the pulling member, and a locking groove that locks the bundle is formed between the locking protrusions. In addition, the bundle body excision device is configured by providing the pair of pulling members so as to be relatively movable in a direction in which the locking protrusion and the locking groove intersect.
[0009]
[Action]
In the bundle excision apparatus according to the first aspect, when one end of the bundle that binds the articles is cut by the cutting means, the other end of the bundle is held by the pulling means. After the bundle is cut by the cutting means, the other end of the bundle held by the pulling means is pulled for an arbitrary length. Bundles pulled by traction means The traction side end portion is supplied by a supply means to a pair of winding members provided in the winding portion of the winding means. After holding the ends of the bundled body by the pair of winding members, the holding of the bundled body by the traction means is released, and the winding unit is moved by an artificial means such as an operator's hand or a mechanical means such as a motor. Rotating in the winding direction and winding the binding body around the outer surface of the winding portion (for example, spiral or spiral), it is possible to reliably prevent the binding body from falling off during winding. It is possible to perform the winding operation of the bundled body reliably and easily. And it is applicable to the operation | work which winds the binding body formed in arbitrary wire diameters or horizontal width. Also, The work of cutting the bundle can be performed accurately and reliably. At the same time, the cut bundles can be prevented from being scattered around, and the work and time for collecting the bundles can be saved.
[0010]
In the bundle excision device according to claim 2, in combination with the operation according to claim 1, the engaging projections formed on the pair of pulling members are bitten or pierced on the outer surface of the article, and then the vertical direction or the horizontal direction. To the locking groove formed between the locking projections, and guides the binding body, and the binding protrusions and the locking grooves formed on the pair of pulling members intersect with each other in a staggered state. Since it is held, it can be reliably held even if the bundle is immersed or bitten inside the outer surface of the article. At the time of towing, it is possible to reliably prevent the bound body from falling, and to reliably separate and tow the bound body from the outer surface of the article.
[0011]
【The invention's effect】
According to the present invention, when one end of the binding body is cut by the cutting means, the other end of the binding body is held by the traction means, so that at the time of cutting, the binding body moves up and down or the winding position is displaced. And the work of cutting the bound body can be performed accurately and reliably. Moreover, since the bundle held by the traction means is pulled and the pulled bundle is wound by the winding means, it is possible to prevent the cut bundles from being scattered around like the conventional example. In addition, the work and time for collecting the bundle can be saved, and the work for cutting and collecting the bundle can be performed mechanically, thereby saving labor and increasing efficiency. Moreover, by winding the bundle in a spiral or spiral shape, there is no need to fold or bundle the bundle at the time of collection, and the space for stocking the bundle is small. The bundles can be easily collected and handled.
[0012]
Further, after engaging or piercing the outer surface of the article with the locking protrusions formed on the pair of pulling members, the locking protrusions and the locking grooves intersect with each other in a staggered state, and the locking protrusions formed between the locking protrusions Since the bundling body is guided and held in the groove, it can be reliably held even if the bundling body is immersed or bitten inside the outer surface of the article. During towing, the bundle can be reliably prevented from falling, and the cut and bound body can be reliably separated and pulled.
[0013]
Furthermore, since the winding unit is rotated in the winding direction by artificial means or mechanical means to wind the binding body, the binding body is wound, for example, spirally or spirally on the outer surface of the winding part. Can be wound, and the winding work of the bundle can be easily performed. In addition, by moving the pair of winding members in an arbitrary direction and holding the ends of the bundle, it is possible to reliably prevent the bundle from falling off during winding. The work can be performed reliably and can be applied to the work of winding a bundle formed in an arbitrary wire diameter or width.
