Description

【０００１】
【発明の属する技術分野】
この発明は、例えば、天井部、壁部、床部用のボード（石膏ボード、木製ボード、樹脂製ボード）等の方形板を包装する作業に用いられる方形板包装装置に関する。
【０００２】
【従来の技術】
従来、上述例のようなボードの端部を包装する場合、例えば、複数枚のボードを積重ねてなるボード群の両端部に、ボード群の端部が覆われる大きさに形成したシート（例えば段ボール紙等）を作業者の手で折曲げて被覆する方法がある。
【０００３】
【発明が解決しようとする課題】
しかし、上述のように作業者の手で折曲げたシートをボード群の端部に被覆するので、ボード群の端部外面と対応する寸法にシートを折曲げることが困難であり、シートの折曲げ方法が作業者によって若干異なるため、被覆後に於いて、シートの被覆位置がズレたり、シートが脱落したりすることがある。且つ、ボード群の両端部に対してシートを手作業により１枚ずつ被覆するので、シートを被覆する作業に手間及び時間が掛かるという問題点を有している。
【０００４】
また、複数枚のボードを表面側が上向きとなる状態に積重ねた場合、最上層に積重ねられたボードの表面側が露出するため、運搬時に於いて、ボード群の最上層に積重ねられたボードの表面側にキズが付きやすく、ボードの商品価値及び施工精度が損なわれるという問題点を有している。
【０００５】
この発明は上記問題に鑑み、板体又は板群の端部に対して該端部が覆われる形態にシート状の被覆部材を成形して被覆するので、板体又は板群の厚みに対応して、その端部外面に対して被覆部材を確実に被覆することができる方形板包装装置の提供を目的とする。
【０００６】
【課題を解決するための手段】
請求項１記載の発明は、方形に形成した一枚の板体又は複数枚の板体を積重ねてなる板群の端部と対向して、上記板体又は板群の端部が覆われる大きさに形成したシート状の被覆部材を、該板体又は板群の端部と対応する形態に成形して被覆する被覆手段を設けた方形板包装装置であって、上記被覆手段を、上記被覆部材を吸着保持する装填板と、該装填板と対向する姿勢と上記板体又は板群の端部に対向する姿勢とに移動可能で、上記装填板により吸着された上記被覆部材が押し込まれることにより該被覆部材を上記板体又は板群の端部が覆われる形態に折曲げ成形する装着台とから構成した方形板包装装置であることを特徴とする。
【０００７】
請求項２記載の発明は、上記請求項１記載の構成と併せて、上記板体又は板群の厚みと対応する方向に、該板体又は板群の端部に被覆された被覆部材を押圧する押圧手段を上記装着台に設けた方形板包装装置であることを特徴とする。
【０００８】
請求項３記載の発明は、上記請求項１又は２記載の構成と併せて、上記板体又は板群の端部に被覆された被覆部材のフラップを折重ねた状態に重合固定する折重ね手段を上記装着台に設けた方形板包装装置であることを特徴とする。
【０００９】
【作用】
請求項１記載の方形板包装装置は、装填板により吸着保持されたシート状の被覆部材を装着台に押し込んで、被覆部材を、板体又は板群の端部が覆われる形態に折曲げ形成した後、装着台を、板体又は板群の端部と対向する姿勢に移動して、装填台に押し込まれた折曲げ済みの被覆部材を、一枚の板体又は複数枚の板体を積重ねてなる板群の端部（例えば両端部、周縁部）に被覆するので、板体又は板群の厚みに対応して、その端部外面に対して被覆部材を確実に被覆することができ、板体の端部が破損又は損傷するのを防止することができる。
【００１０】
請求項２記載の方形板包装装置は、上記請求項１記載の作用と併せて、板体又は板群の厚みと対応する方向に、板体又は板群の端部に被覆された被覆部材を押圧手段により押圧するので、その端部外面に対して被覆部材を密着した状態に被覆することができる。
【００１１】
請求項３記載の方形板包装装置は、上記請求項１又は２記載の作用と併せて、板体又は板群の端部に被覆された被覆部材のフラップを折重ね手段により折曲げて、互いに折重ねた状態に重合固定するので、板体又は板群の端部外面に対して被覆部材を確実に被覆固定することができ、被覆部材がズレたり、脱落したりするのを防止することができる。
【００１２】
【発明の効果】
この発明によれば、板体又は板群の端部が覆われる形態に被覆部材を成形して被覆するので、板体又は板群の厚みに対応して、その端部外面に対して被覆部材を確実に被覆することができ、板体の端部が破損又は損傷するのを防止することができる。且つ、被覆部材を被覆する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。
【００１３】
しかも、板体又は板群の厚みに応じて、板体又は板群の端部に被覆した被覆部材を押圧するので、その端部外面に対して密着した状態に被覆部材を被覆することができ、端部外面と対応する寸法に被覆部材を被覆する作業が正確且つ容易に行える。
【００１４】
さらに、板体又は板群の端部に被覆した被覆部材のフラップを互いに折重ねた状態に重合固定することで、その端部外面に対して被覆部材を確実に被覆固定することができ、被覆位置がズレたり、脱落したりするのを防止することができる。且つ、板群の最上層に積載される板体を表裏反転して積重ねることで、板体の表面側にキズが付くのを確実に防止することができ、板体の商品価値及び施工精度が損なわれるのを防止することができる。
【００１５】
【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。
図面は板体の一例として、複数枚のボードを積重ねてなるボード群の両端部にシートを被覆する作業に用いられる方形板包装装置を示し、図１に於いて、この方形板包装装置１は、例えば、長方形、正方形等の方形に形成されたボードＡ（例えば天井用のボード）を積重ねる積重ね装置２の後段側に配設され、同装置で積重ねたボード群Ｂの両端部（長辺側）に、例えば、段ボール紙、合成樹脂等で形成されたシートＣをボード群Ｂの端部が覆われる形態に折曲げて被覆する。
【００１６】
上述した積重ね装置２は、図２、図３にも示すように、供給コンベア５と、分配コンベア６とを搬送方向に対して直列に配設し、装置前段の供給工程（図示省略）から供給されるボードＡを供給コンベア５で搬送して、分配コンベア６に１枚ずつ移載する。始端側に配設した揺動コンベア７は、水平方向にボードＡが搬送される搬送姿勢と、斜め下方にボードＡが排出される排出姿勢とに上下揺動され、不良品のボードＡが通過するとき、揺動コンベア７を排出姿勢に揺動して、同側下部に配設した排出コンベア８に不良品のボードＡを移載する。排出コンベア８は、装置側部の回収工程（図示省略）に不良品のボードＡを供給する。
【００１７】
分配コンベア６は、搬送路両側部に張架した周回チェーン６ａ，６ａ間に、ボードＡが載置される間隔に隔ててローラ６ｂを複数本軸架し、複数本のローラ６ｂを一組として、ボードＡが落下される間隔に隔てて複数組架設し、各組のローラ６ｂ…上に載置されたボードＡを、搬送路上に設定した分配部ａ，ｂ，ｃに対してサイズ別に搬送する。
【００１８】
搬送路上に配設した検知センサＳ１，Ｓ２，Ｓ３はボードＡのサイズを検知し、その検知に基づいて、サイズ別に配設したストッパ１０を作動する。ストッパ１０は、ボードＡの搬送が許容される待機位置と、ボードＡに当接される旋回位置とに回動され、ストッパ１０で停止したボードＡを、分配部ａ，ｂ，ｃ下部に配設した昇降台１１に１枚ずつ落下供給して積重ねる。なお、ローラ６ｂに代えて、例えば、棒、板等の部材を架設してもよい。
【００１９】
昇降台１１は、ボードＡが載置される上昇位置と、ボードＡ又はボード群Ｂが移載コンベア１２に載置される降下位置とに上下動される。分配部ａに配設した移載コンベア１２は、同位置側部に配設した反転機１４の昇降コンベア１５にボードＡを１枚移載し、分配部ｂ，ｃに配設した移載コンベア１２は、各位置側部に配設した積替え機１９の昇降コンベア２０にボード群Ｂを移載する。
【００２０】
反転機１４は、昇降コンベア１５に移載されたボードＡの上下面を保持アーム１６，１６で押圧保持して表裏反転（裏面側が上向きとなる状態、例えば約１８０度反転）する。昇降コンベア１５は、移載コンベア１２上のボードＡが移載される上昇位置と、その反転が許容される降下位置とに上下動される。

昇降コンベア１５の両側部に架設した移載コンベア１７は、上述したボードＡの移載及び反転が許容される降下位置と、積替え機１９上部に架設した搬送コンベア１８に反転済みのボードＡが移載される上昇位置とに上下動され、反転後に於いて、反転済みのボードＡを移載コンベア１７で持上げて、搬送コンベア１８に１枚ずつ移載する。
【００２２】
搬送コンベア１８は、反転済みのボードＡを分配コンベア６に平行して搬送し、終端側に配設した積重ね機２３に供給する。なお、昇降コンベア１５を水平回転して、反転済みのボードＡを搬送コンベア１８に移載してもよい。
【００２３】
上述した積替え機１９は、昇降コンベア２０に移載されたボード群Ｂを、上述の搬送コンベア１８下部に架設した搬送コンベア２１に移載し、積重ね機２３の移載コンベア２４に対して１群ずつ移載する。昇降コンベア２０は、移載コンベア１２上のボード群Ｂが移載される上昇位置と、搬送コンベア２１にボード群Ｂが移載される降下位置とに上下動される。
【００２４】
積重ね機２３は、搬送コンベア１８により搬送される反転済みのボードＡを吸着ユニット２６で吸着保持し、移載コンベア２４又は昇降コンベア２５に載置されたボード群Ｂの最上面に積載する。吸着ユニット２６に垂設した吸着子２７は、例えば、吸気用ブロワ、真空ポンプ等の負圧発生手段（図示省略）に接続され、その負圧により反転済みのボードＡを吸着保持する。
【００２５】
吸着ユニット２６は、搬送コンベア２１に載置された反転済みのボードＡの上方と、移載コンベア２４に載置されたボード群Ｂの上方とに水平移動される。且つ、反転済みのボードＡの上方に於いて、ボードＡの裏面側に対して吸着子２７が密着される高さに降下され、ボード群Ｂの上方に於いて、吸着子２７で吸着保持したボードＡがボード群Ｂの最上層に積重ねられる高さに降下される。
【００２６】
移載コンベア２４の間に配設した昇降コンベア２５は、ボード群Ｂの移載が許容される降下位置と、方形板包装装置１の搬送コンベア２９にボード群Ｂが移載される上昇位置とに上下動され、反転済みのボードＡが積載されたボード群Ｂを昇降コンベア２５で持上げて搬送コンベア２９に１群ずつ移載する。
【００２７】
移載コンベア２４の前後部に配設した揃え板３０，３２は、移載コンベア２４に載置されたボード群Ｂの前後端部と対向して設けられ、揃え板３０は、同側上部に配設した回動用シリンダ３１によりボード群Ｂの後端部に対して当接される方向に上下回動し、揃え板３２は、同側上部に配設した進退用シリンダ３３によりボード群Ｂの前端部に対して当接される方向に前後動する。

【００３５】
一方、装着位置ｄ側部に配設した可動枠６２は、基台６３上面に敷設したレール６４に対して走行可能に取付けられ、装着位置ｄに供給されるボード群Ｂの横幅に対応して任意位置に移動調節される。可動枠６２の上面側に取付けた可動台６５は、可動枠６２側部に取付けた進退用シリンダ６６により、昇降台３５に載置されたボード群Ｂの端部に対してシートＣが装着される前進位置と、装着台４５の回動が許容される後退位置とに前後動される。
【００３６】
可動台６５の上面側に軸支した支持台６７は、可動台６５側部に取付けた回動用シリンダ６８により、装填ユニット５２の装填板５５と対向する上向き姿勢と、昇降台３５に載置されたボード群Ｂの端部と対向する横向き姿勢とに回動（例えば約９０度）される。支持台６７下部に配設した当接板６９は、装着位置ｄに搬送されたボード群Ｂの端部と対向して設けられ、可動枠６２に固定した進退用シリンダ７０によりボード群Ｂの端部に対して当接される方向に前後動される。
【００３７】
支持台６７の上面側に取付けた凹状の装着台４５は、上述した装填板５５と合致する形状に形成され、左右の受け板７１，７１を幅方向に対して拡縮可能に取付けると共に、支持台６７上に固定した拡縮用シリンダ７２により、一方又は両方の受け板７１を幅方向に対して拡縮移動する。

【００３９】
支持台６７の両端部に取付けた折込み板７６，７７，７８は、装着台４５に装填されるシートＣのフラップＣａ，Ｃｂ，Ｃｃと対向して配設され、折込み板７６，７７は、同側端部に固定した押圧用シリンダ７９及び進退用シリンダ８０により、ボード群Ｂの端部（前端又は後端）に対してシートＣのフラップＣａ，Ｃｂが折曲げられる方向に交互又は同時に移動される。折込み板７８は、同側端部に固定した押圧用シリンダ８１及び進退用シリンダ８２により、ボード群Ｂの端部に対してシートＣのフラップＣｃが折曲げられる方向に移動される。
【００４０】
受け板７１と対向して支持台６７の両端部に取付けた一対の押圧板８３は、同側端部に固定した押圧用シリンダ８４により、受け板７１に形成した切欠き部を介して、装着台４５に装填されたシートＣの両側面に対して押圧される方向に進退移動される。なお、一端側の受け板７１と、折込み板７６，７７，７８と、押圧板８３とを、支持台６７の一端側に取付けた補助台８５に取付け、同側下面に固定した進退用シリンダ８６により、装着台４５に装填されるシートＣの全長に対応して任意位置に拡縮移動する。
【００４１】
前述した装填部４６は、図８、図９に示すように、多数枚のシートＣが積載される大きさに形成した底板８７を下部中央に配設し、底板８７の左右及び前後には、シートＣの長辺側及び短辺側が支持される間隔に隔てて支持板８８を立設している。支持板８８は、シートＣの幅及び長さに対応して任意間隔に拡縮調節可能に取付けられている。
【００４２】
底板８７の一側部は、同側に立設したネジ軸８９に対して上下動可能に取付けられ、同側下部に配設した減速機付き昇降用モータ９０（例えばステッピングモータ）によりネジ軸８９を正逆回転して、最上面に積重ねられたシートＣが装填ユニット５２の吸着子５８で吸着保持される高さに底板８７を上下動する。
【００４３】
且つ、底板８７上には、図１０、図１１に示すように、ボード群Ｂの厚み又は枚数に対応して、その側端部が覆われるサイズに形成したシートＣ（例えば８枚用、４枚用）を多数枚載置する。なお、異なるサイズのシートＣを別々に装填してもよい。また、ロール状に巻回されたシートＣを、ボードＡ又はボード群Ｂの端部が被覆される大きさに１枚ずつ分離して装着台４５に装填してもよい。
【００４４】
装填部４６上方と装着台４５上方との間に配設した前後の噴射器９１は、装填ユニット５２で吸着保持したシートＣのフラップＣａ，Ｃｂ，Ｃｃと対向して任意角度に可変調節可能に設けられ、装填ユニット５２で吸着保持したシートＣを装填部４６上方に移動するとき、フラップＣｃ又はＣａ，Ｃｂの所定箇所に対して接着剤Ｄ（例えばホットメルト等）を吹き付ける。
【００４５】
図示実施例は上記の如く構成するものにして、以下、方形板包装装置１によりボード群Ｂの両端部に対してシートＣを被覆する作業を説明する。
先ず、図１、図２に示すように、供給コンベア５に載置されたボードＡ（例えば長方形又は正方形）を分配コンベア６に順次移載し、検知センサＳ１，Ｓ２，Ｓ３による検知に基づいて、分配部ａ，ｂ，ｃに配設した昇降台１１にボードＡを落下供給する。なお、不良品のボードＡが搬送されたとき、揺動コンベア７を揺動して、排出コンベア８に移載し、回収工程（図示省略）に供給する。
【００４６】
分配部ａの昇降台１１にボードＡを載置し、１枚のボードＡのみを移載コンベア１２で搬送して、反転機１４の昇降コンベア１５に移載する。分配部ｂ，ｃの昇降台１１にボードＡを複数枚積重ねた後、複数枚のボードＡを積重ねてなるボード群Ｂを移載コンベア１２で搬送して、積替え機１９の昇降コンベア２０に移載する。
【００４７】
次に、図３に示すように、昇降コンベア１５に載置されたボードＡを反転機１４の保持アーム１６，１６で保持して表裏反転した後、保持アーム１６，１６による保持を解除して、反転済みのボードＡを移載コンベア１７に移載し、搬送コンベア１８にボードＡを移載する。一方、積替え機１９の昇降コンベア２０に載置されたボード群Ｂを搬送コンベア２１で搬送して、積重ね機２３の移載コンベア２４に移載する。
【００４８】
次に、搬送コンベア１８により搬送される反転済みのボードＡを積重ね機２３の吸着ユニット２６で吸着保持して、移載コンベア２４又は昇降コンベア２５に載置されたボード群Ｂの最上面に積載する。ボード群Ｂの前後端部に揃え板３０，３２を当接してセンターリング及び垂直に揃えた後、揃え板３０，３２を初期位置に復帰させて、所定枚数（例えば４枚、８枚）のボードＡが積重ねられたボード群Ｂを、方形板包装装置１の搬送コンベア２９に移載する。
【００４９】
次に、図４、図５に示すように、搬送コンベア２９上の装着位置ｄにボード群Ｂが搬送されたとき、ボード群Ｂの両端部に当接板６９を当接して垂直に揃えた後、昇降台３５によりボード群Ｂを持上げ、ボード群Ｂの前後端部に揃え板３９，４１を当接して垂直に揃える。
【００５０】
一方、装着機４４の装填ユニット５２を装填部４６上方に移動して、装填部４６に装填された最上層のシートＣを吸着子５８で吸着保持する。そのシートＣを装填部４６上方に移動するとき、シートＣに形成したフラップＣｃの適宜箇所に、噴射器９１から吐出される接着剤Ｄを適量吹き付ける。また、フラップＣａ，Ｃｂの裏面側に接着剤Ｄを吹き付けてもよい。
【００５１】
次に、図６、図７に示すように、装填ユニット５２を装着台４５上方に移動して、図１２に示すように、吸着子５８で吸着保持したシートＣを装着台４５に押し込み、装填板５５と装着台４５とを互いに合致して、ボード群Ｂの端部が覆われる形態にシートＣを折曲げ成形する。また、装填板５５の押え板５６，５６と、装着台４５の受け板７１，７１とで押圧して、シートＣを成形してもよい。
【００５２】
且つ、図１３に示すように、装着台４５に取付けた吸着子７３でシートＣを吸着保持し、装填ユニット５２を上昇して、装着台４５から装填板５５を抜き取る。また、装填板５５の押え板５６，５６を近接し、装着台４５の受け板７１，７１を離間してから、装填板５５を抜き取ってもよい。装填ユニット５２による吸着を解除して、装填ユニット５２を装填部４６上方に移動させ、次のシートＣを吸着保持して、シートＣの装填作業を継続して行う。
【００５３】
次に、装着台４５を横向き姿勢に回転して、ボード群Ｂの端部と対向する方向に移動する。図１４に示すように、ボード群Ｂの端部に装着台４５を嵌合して、装着台４５に装填されたシートＣをボード群Ｂの端部に装着する。
【００５４】
ボード群Ｂに被覆されたシートＣの上下面を、ボード群Ｂの厚みと対応する方向に押圧板８３で押圧する。また、装着台４５の受け板７１，７１により押圧してもよい。図１５、図１６、図１７に示すように、シートＣのフラップＣａ，Ｃｂを折込み板７６，７７で折曲げる。続いて、図１８に示すように、フラップＣｃを折込み板７８で折曲げて、先に折曲げられたフラッブＣａ，Ｃｂに重合すると共に、フラップＣａ，Ｃｂ，Ｃｃを押圧して接着剤Ｄにより接着固定する。
【００５５】
次に、板７６，７７，７８，８３を初期位置に復帰させた後、ボード群Ｂに被覆されたシートＣを排除板７４で押圧し、吸着子７３による吸着を解除した後、装着台４５の受け板７１，７１を離間し、ボード群Ｂの端部に排除板７４を押圧したまま、装着台４５を初期位置に後退復帰させる。続いて、排除板７４を初期位置に復帰させ、装着台４５を上向き姿勢に回動復帰させた後、次のシートＣを装填する。
【００５６】
次、揃え板３９，４１を初期位置に復帰させ、ストッパ１０を没入した後、昇降台３５を垂直降下して、シートＣが被覆されたボード群Ｂを搬送コンベア２９に載置し、次工程に搬送供給する。以下同様にして、次のボード群Ｂを装着位置ｄに搬送し、シートＣを被覆する作業を継続して行う。
【００５７】
以上のように、ボード群Ｂの端部が覆われる形態にシートＣを折曲げて被覆するので、ボード群Ｂの厚みに対応して、その端部外面に対してシートＣを確実に被覆することができ、ボードＡの端部が破損又は損傷するのを防止することができる。且つ、ボード群Ｂの端部を被覆する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。
【００５８】
しかも、ボード群Ｂの厚みに応じて、その端部に被覆されたシートＣを押圧するので、ボード群Ｂの端部に対して密着した状態にシートＣを被覆することができ、且つ、ボード群Ｂの端部外面と対応する寸法にシートＣを被覆する作業が正確且つ容易に行える。
【００５９】
さらに、ボード群Ｂに被覆されたシートＣのフラップＣａ，Ｃｂ，Ｃｃを互いに折重ねた状態に重合固定するので、その端部外面に対してシートＣを確実に被覆固定することができ、被覆位置がズレたり、脱落したりするのを防止することができる。
【００６０】
且つ、ボード群Ｂの最上層に積載されるボードＡを表裏反転して積重ねるので、ボードＡの表面側にキズが付くのを確実に防止することができ、ボードＡの商品価値及び施工精度が損なわれるのを防止することができる。
【００６１】
