Description

【０００１】
【発明の属する技術分野】
本発明は、共通の組み立てラインによりウオール用箱体、フロアー用箱体を選択的に組み立てる箱体の組み立て方法に関するものである。
【０００２】
【従来の技術】
従来システムキッチン等に用いる箱体としては、大別して下記の２種類がある。
【０００３】
その一つは、壁面に取付けられるウオール用箱体と称されるものであって、その基本形態は、左右の側板と、左右の側板の上下端部間に配設される天板及び地板と、左右の側板の内面の後端部に設けた嵌め込み溝と上下の天板及び地板の各内面の後端部に設けた嵌め込み溝とに４辺が嵌め込まれる裏板と、裏板の後面側に配設される裏桟とを組み立てて構成される。
【０００４】
他の一つは、床に設置されて上面に別体のカウンターが載設されるフロアー用箱体と称されるものであって、その基本形態は、左右の側板と、左右の側板の上端部間の前端部と後端部とに架設される天前桟及び天後桟と、左右の側板の下端部間に配設されて後端部が側板の後端部よりも前方に位置する地板と、左右の側板の内面の後端部に設けた嵌め込み溝と天後桟の内面に設けた嵌め込み溝とに３辺が嵌め込まれる裏桟付きの裏板とを組み立てて構成される。
【０００５】
従来上記２種類の箱体を組み立てるに当たっては、別々の組み立てラインにより組み立てられており、このように、別々の組み立てラインが必要なため、工場内において組み立てに要する広いスペースが必要であり、また、別々の組み立てラインで組み立てるので、各組み立てラインにそれぞれ作業者が必要であり、組み立て効率も悪くて生産性が悪いという問題がある。
【０００６】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、異なる種類の箱体を共通の組み立てラインで選択的に組み立てることができて、組み立てに要するスペースが従来に比べて狭いスペースでよく、また、組み立て効率も良くなって生産性が向上する箱体の組み立て方法を提供することを課題とするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明に係る箱体の組み立て方法は、左右の側板１と、左右の側板１の上下端部間に配設される天板３及び地板４と、左右の側板１の内面の後端部に設けた嵌め込み溝２ａと上下の天板３及び地板４の各内面の後端部に設けた嵌め込み溝２ｂ、２ｃとに４辺が嵌め込まれる裏板５と、裏板５の後面側に配設される裏桟６とよりなるウオール用箱体７と、左右の側板１と、左右の側板１の上端部間の前端部と後端部とに架設される天前桟８及び天後桟９と、左右の側板１の下端部間に配設されて後端部が側板１の後端部よりも前方に位置する地板４と、左右の側板１の内面の後端部に設けた嵌め込み溝２ａと天後桟９の内面に設けた嵌め込み溝２ｄとに３辺が嵌め込まれる裏桟６付きの裏板５とよりなるフロアー用箱体１０とを共通の組み立てライン１１により選択的に組み立てる箱体の組み立て方法であって、ウオール用箱体７を組み立てるに当たっては、左右の側板１を内面同士が向き合うように組み立て完成後の両側板１間の距離よりも長い距離を隔ててプレス手段１２に対向保持すると共に、両側板１の上下両端部間に天板３と地板４とを内面同士が向き合うように組み立て完成後における天板３と地板４との距離と同じ距離を隔てて保持手段１３により対向保持し、次に、対向する天板３と地板４の後端部間に嵌め込み溝２ｂ、２ｃと平行な方向から裏板５を裏板移動手段１４により移動しながら裏板５の対向する一対の辺を対向する天板３の嵌め込み溝２ｂと地板４の嵌め込み溝２ｃとに嵌め込み、次に、プレス手段１２により両側板１を互いに近づく方向に移動して天板３と地板４とを嵌合部１５により嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みすると共に両側板１の嵌め込み溝２ａを裏板５の対向する他の一対の辺に嵌め込み、次に、裏板５の後面と天板３乃至地板４の内面とのなす角部に裏桟６を配置して固定し、その後、プレス手段１２により両側板１間の距離が完成後における距離と同じ距離となるまで移動して嵌合部１５が本嵌合するようにプレスすることでウオール用箱体７を本組み立てし、一方、フロアー用箱体１０を組み立てるに当たっては、左右の側板１を内面同士が向き合うように組み立て完成後の側板１間の距離よりも長い距離を隔ててプレス手段１２に対向保持すると共に、両側板１の上下方向の一端部間に地板４を、上下方向の他端部の前端間に天前桟８を、後端間に天後桟９をそれぞれ配置して天前桟８の内面が地板４の内面と対向し且つ天後桟９の内面に設けた嵌め込み溝２ｄの開口前縁が地板４の後端縁と対向するように天前桟８と天後桟９と地板４とがそれぞれ組み立て完成後と同じ位置関係で保持手段１３により保持し、次に、プレス手段１２により両側板１を互いに近づく方向に移動して地板４と天前桟８と天後桟９のそれぞれの両端部を両側板１に嵌合部１５により嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みし、次に、地板４の後端よりも後方において地板４と直交する方向からあらかじめ裏桟６を取付けた裏板５を裏板移動手段１４により移動しながら裏板５の対向する一対の辺を対向する側板１の嵌め込み溝２ａに嵌め込んで裏板５の他の対向する辺のうちの一辺を天後桟９の内面に設けた嵌め込み溝２ｄに嵌め込み、その後、プレス手段１２により両側板１間の距離が完成後における距離と同じ距離となるまで移動して嵌合部１５が本嵌合するようにプレスすることでフロアー用箱体１０を本組み立てすることを特徴とするものである。
【０００８】
このような方法を採用することで、共通の組み立てライン１１によりウオール用箱体７とフロアー用箱体１０とを選択的に組み立てることができるものである。
【０００９】
また、共通の組み立てライン１１に設けたプレス手段１２を第１のプレス手段１２ａと第２のプレス手段１２ｂとで構成し、共通の組み立てライン１１に設けた裏板移動手段１４を第１の裏板移動手段１４ａと第２の裏板移動手段１４ｂとで構成し、ウオール用箱体７を組み立てるに当たっては、左右の側板１を内面同士が向き合うように組み立て完成後の両側板１間の距離よりも長い距離を隔てて第１のプレス手段１２ａに対向保持すると共に、両側板１の上下両端部間に天板３と地板４とを内面同士が向き合うように組み立て完成後における天板３と地板４との距離と同じ距離を隔てて保持手段１３により対向保持し、次に、対向する天板３と地板４の後端部間に嵌め込み溝２ｂ、２ｃと平行な方向から裏板５を第１の裏板移動手段１４ａにより移動しながら裏板５の対向する一対の辺を対向する天板３の嵌め込み溝２ｂと地板４の嵌め込み溝２ｃとに嵌め込み、次に、第１のプレス手段１２ａにより両側板１を互いに近づく方向に移動して天板３と地板４とを嵌合部１５により嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みすると共に両側板１の嵌め込み溝２ａを裏板５の対向する他の一対の辺に嵌め込み、次に、裏板５の後面と天板３乃至地板４の内面とのなす角部に裏桟６を配置して固定し、その後、第２のプレス手段１２ｂにより両側板１間の距離が完成後における距離と同じ距離となるまで移動して嵌合部１５が本嵌合するようにプレスすることでウオール用箱体７を本組み立てし、一方、フロアー用箱体１０を組み立てるに当たっては、左右の側板１を内面同士が向き合うように組み立て完成後の側板１間の距離よりも長い距離を隔てて第１のプレス手段１２ａに対向保持すると共に、両側板１の上下方向の一端部間に地板４を、上下方向の他端部の前端間に天前桟８を、後端間に天後桟９をそれぞれ配置して天前桟８の内面が地板４の内面と対向し且つ天後桟９の内面に設けた嵌め込み溝２ｄの開口前縁が地板４の後端縁と対向するように天前桟８と天後桟９と地板４とをそれぞれ組み立て完成後と同じ位置関係で保持手段１３により保持し、次に、第１のプレス手段１２ａにより両側板１を互いに近づく方向に移動して地板４と天前桟８と天後桟９のそれぞれの両端部を両側板１に嵌合部１５により嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みし、次に、地板４の後端よりも後方において地板４と直交する方向からあらかじめ裏桟６を取付けた裏板５を第２の裏板移動手段１４ｂにより移動しながら裏板５の対向する一対の辺を対向する側板１の嵌め込み溝２ａに嵌め込んで裏板５の他の対向する辺のうちの一辺を天後桟９の内面に設けた嵌め込み溝２ｄに嵌め込み、その後、第２のプレス手段１２ｂにより両側板１間の距離が完成後における距離と同じ距離となるまで移動して嵌合部１５が本嵌合するようにプレスすることでフロアー用箱体１０を本組み立てするようにすることを特徴とすることも好ましい。
【００１０】
このような方法を採用することで、共通の組み立てライン１１に設けた第１の裏板移動手段１４ａで裏板５を移動して嵌め込み溝２ｂ、２ｃに嵌め込むと共に仮り組み用の第１のプレス手段１２ａで両側板１、天板３、地板４、裏板５とでウオール用箱体７を仮組みし、この仮組みしたウオール用箱体７を第２のプレス手段１２ｂで本組み立てでき、また、第１のプレス手段１２ａで両側板１、地板４、天前桟８、天後桟９とでフロアー用箱体１０を仮組みし、この仮組みしたフロアー用箱体１０に第２の裏板移動手段１４ｂにより裏桟６付きの裏板５を嵌め込むと共に第２のプレス手段１２ｂで本組み立てできるものである。
【００１１】
また、ウオール用箱体７を組み立てるに当たって、プレス手段１２により内面部の後端部に嵌め込み溝２ａを有する左右の側板１を内面同士が向きあうように組み立て完成後の側板１間の距離よりも長い距離を隔てて対向保持している段階で一方の側板１の後端が他方の側板１の嵌め込み溝２ａの開口の前縁よりも前方に位置するようにずらし、この前方にずれて位置する方の側板１の後端よりも後方において該側板１と直交する方向から裏板５の対向する一対の辺を対向する天板３と地板４の嵌め込み溝２ｂ、２ｃに嵌め込み、その後、前方にずれている方の側板１を後方に移動して対向する側板１の嵌め込み溝２ａ同士が対向するようにした後にプレス手段１２により両側板１を互いに近づく方向に移動して天板３と地板４とを嵌合部１５により嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みすると共に両側板１の嵌め込み溝２ａを裏板５の対向する他の一対の辺に嵌め込むことを特徴とすることを好ましい。
【００１２】
このような方法を採用することで、裏板移動手段１４により裏板５を移動して裏板５の対向する一対の辺を対向する天板３と地板４の嵌め込み溝２ｂ、２ｃに嵌め込むに当たって、プレスして仮組みするために対向して配置してある一方の側板１に邪魔されることなく裏板５を移動して天板３と地板４の嵌め込み溝２ｂ、２ｃに嵌め込むことが可能となるものであり、裏板５を天板３と地板４の嵌め込み溝２ｂ、２ｃに嵌め込んだ後は前方にずれている方の側板１を後方に移動して対向する側板１の嵌め込み溝２ａ同士が対向するようにした後にプレス手段１２により両側板１を互いに近づく方向に移動してプレスすることで、両側板１の嵌め込み溝２ａを裏板５の対向する他の一対の辺に確実に嵌め込むことができるものである。
【００１３】
また、共通の組み立てライン１１にウオール用箱体７の裏板５、フロアー用箱体１０の裏板５を搬送するための裏板搬送路１６を設け、第１の裏板移動手段１４ａに裏板搬送路１６を搬送されるフロアー用箱体１０の裏板５は通過させてウオール用箱体７の裏板５のみを取り上げる裏板選択取り上げ手段１７を設け、ウオール用箱体７を組み立てる際には第１の裏板移動手段１４ａがウオール用箱体７の裏板５を裏板選択取り上げ手段１７で取り上げて裏板５の嵌め込みのために移動し、フロアー用箱体１０を組み立てる際には裏板選択取り上げ手段１７を通過したフロアー用箱体１０の裏板５を第２の裏板移動手段１４ｂが取り上げて裏板５の嵌め込むために移動することも好ましい。
【００１４】
このような方法を採用することで、共通の裏板搬送路１６にウオール用箱体７の裏板５、フロアー用箱体１０の裏板５を供給しても裏板選択取り上げ手段１７によりウオール用箱体７の裏板５は取り上げるがフロアー用箱体１０の裏板５は通過させて後の第２の裏板移動手段１４ｂで取り上げるようにでき、これにより、裏板５、５の供給搬送を共通の裏板搬送路１６で行うことができるものである。
【００１５】
また、共通の組み立てライン１１によりウオール用箱体７、フロアー用箱体１０を選択的に組み立てるに当たって、組み立てライン１１に備えた上記各手段を組み立てようとする箱体の種類毎に制御するための制御部を設け、共通の組み立てライン１１に各箱体の材料を供給する際に、組み立てようとする箱体の種類を入力する入力部１９を設け、入力部１９で入力した箱体の種類の入力情報に基づき制御部により共通の組み立てライン１１に備えた各手段をあらかじめ登録されている順序、動作で駆動して目的とする種類の箱体を組み立てることも好ましい。
【００１６】
このような方法により、ウオール用箱体７、フロアー用箱体１０というように異なる種類の箱体を共通の組み立てライン１１で組み立てるに当たって、組み立てようとする箱体の材料を共通の組み立てライン１１に供給する際に入力部１９で箱体の種類を入力することで、共通の組み立てライン１１に備えた各手段をあらかじめ登録されている順序、動作で駆動して目的とする種類の箱体を自動的に組み立てることができるものである。
【００１７】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１８】
図１には本発明に用いる共通の組み立てライン１１の概略平面図が示してある。この共通の組み立てライン１１には側板搬送路２０、天板・地板搬送路２１、天前桟・天後桟搬送路２２、裏板搬送路１６、裏桟搬送路２３がそれぞれ並列して設けてある。また、共通の組み立てライン１１の始端部には作業台２４が設けてあり、この作業台２４に組み立てようとする箱体の種類を入力するための入力部１９を構成するバーコード読み取り装置２５が設けてある。作業台２４には組み立てようとするウオール用箱体７やフロアー用箱体１０の１箱分の材料をそれぞれワンセットとして供給する材料供給ライン２６が設けてある。
【００１９】
ウオール用箱体７の１箱分の材料のワンセットとは図２６に示すように、少なくとも左右一対の側板１、天板３及び地板４、裏板５、裏桟６である。ここで左右一対の側板１には前工程であらかじめ内面の後端部に上下全長にわたって嵌め込み溝２ａが形成してあり、更に、内面の上端部及び下端部にそれぞれ前後方向の複数箇所に嵌合孔２７が形成してある。また、天板３には内面の後端部の左右方向の全長にわたって嵌め込み溝２ｂが形成してあり、天板３の両側端面部には前後方向の複数箇所に嵌合突部２８ａとなるダボが突設してある。また、地板４は天板３と平面の形状、大きさが同じであり、この地板４には内面の後端部の左右方向の全長にわたって嵌め込み溝２ｃが形成してあり、地板４の両左右側端面部には前後方向の複数箇所に嵌合突部２８ｂとなるダボが突設してある。裏板５は４辺が上記嵌め込み溝２ａ、２ｂ、２ｃに嵌め込むことができる厚みとなっている。また、裏桟６は長さが天板３、地板４の左右方向の長さと同じ長さとなっている。このウオール用箱体７の１箱分の材料のワンセットの材料にはワンセットの１つの部材又は複数の材料又は全部の材料又は材料の梱包材に当該ウオール用箱体７を特定するバーコードが施してある。
【００２０】
また、フロアー用箱体１０の１箱分の材料のワンセットとは図３１に示すように、少なくとも左右一対の側板１、地板４、天前桟８及び天後桟９、裏桟６付きの裏板５である。ここで左右一対の側板１には前工程であらかじめ内面の後端部に上下全長にわたって嵌め込み溝２ａが形成してあり、更に、内面の上端部及び下端部にそれぞれ前後方向の複数箇所に嵌合孔２７が形成してある。また、地板４は側板１よりも前後長さが短く、地板４の前後長さは側板１の前端から嵌め込み溝２ａの開口の前縁までの長さとなっており、地板４の両左右側端面部には前後方向の複数箇所に嵌合突部２８ｂとなるダボが突設してある。天前桟８は長さが地板４の左右方向と同じ長さであり、左右方向の両端面部に嵌合突部２８ｃとなるダボが突設してある。天後桟９は長さが地板４の左右方向と同じ長さであり、左右方向の両端面部に嵌合突部２８ｄとなるダボが突設してあり、この天後桟９の内面には左右方向にわたって嵌め込み溝２ｄが形成してある。裏板５の後面の上下方向の一端部（完成品においては上端部）にあらかじめ裏桟６を固着してあり、この裏桟６は天後桟９と同じ長さであって裏桟６の左右方向の両端部が裏板５の左右方向の両端部よりも少し内側に引き込んで位置しており、裏板５の左右両端部の裏桟６の両端部よりも突出している部分の上下全長及び裏板５の裏桟６を固着してい内方の上下方向の他端縁部嵌め込み溝２ａ、２ｄに嵌め込む部分となっている。このフロアー用箱体１０の１箱分の材料のワンセットの材料にはワンセットの１つの材料又は複数の材料又は全部の材料又は材料の梱包材に当該フロアー用箱体１０を特定するバーコードが施してある。
【００２１】
材料供給ライン２６からウオール用箱体７の材料のワンセット、あるいはフロアー用箱体１０の材料のワンセットが作業台２４に供給されると、バーコード読み取り装置２５により共通の組み立てライン１１に供給して組み立てようとする箱体の種類に関する情報が読み取られてコンピュータよりなる制御部（図示せず）に入力される。材料を梱包材で梱包しているときは作業台２４で梱包を解く。
【００２２】
作業台２４に供給されたワンセット分の材料は作業者の人力又は材料供給ロボットによりそれぞれの材料を搬送する該当する搬送路の始端部に供給される。
【００２３】
次に、各搬送路につき説明する。
【００２４】
側板搬送路２０は図２に示すようなもので、この側板搬送路２０には組み立てる箱体がウオール用箱体７の場合、フロアー用箱体１０の場合のいずれであっても、該当する組み立てるべき箱体の左右一対の側板１が供給される。図３に示すように、側板搬送路２０の始端部に巾方向と、巾方向の一端部において長手方向にストッパ２９がＬ状となるように設けてあって、左右の側板１を嵌合孔２７を設けた内面側を上にして図３（ａ）のように側板搬送路２０に前後に間隔を隔てて載置し（実施形態では進行方向の前方に左の側板１を載置し、進行方向の後側に右の側板１を配置するようになっている）、両側板１をそれぞれ側板搬送路２０の巾方向の一端部側において長手方向に設けたストッパ２９に当てて位置決めするようになっている。ここで、側板搬送路２０には側板１の高さ方向の寸法を検知するための寸法検知手段３０ａが設けてあって、側板搬送路２０に供給された両側板１の高さ方向の寸法を検知するようになっている。図３（ｂ）に示す実施形態においては、側板搬送路２０がローラコンベアにより構成してあり、側板搬送路２０の搬送方向の２箇所においてローラコンベア間に巾方向にわたってそれぞれ複数のリミットスイッチ３１ａが設けてあり、両側板１を側板搬送路２０の前後に載置して両側板１をそれぞれ長手方向のストッパ２９に当てて位置決めした状態で、上記リミットスイッチ３１ａにより両側板１の寸法を検出するようになっている。そして、このようにして検出された寸法情報が前述の入力部１９で入力された組み立てようとする箱体の種類の情報で特定された側板１の寸法と同じであるか否かが制御部に設けた判定手段により判定され、検出した寸法が入力部１９で入力した組み立てようとする箱体の側板のあらかじめ登録してある寸法と異なる場合には、警告ランプや警告ブザー等の警告手段（図示せず）が動作して、当該箱の組み立ては中止される。このようにして側板搬送路２０へ左右一対の側板１の供給が完了すると作業者は側板投入完了釦３２ａを押す。
【００２５】
側板搬送路２０の先には図１、図２、図４に示すように接着剤塗布部３３が設けてあり、この接着剤塗布部３３には図４に示すように、進行方向の前後に塗布用前ベルトコンベア３４ａと塗布用後ベルトコンベア３４ｂとが設けてある。
【００２６】
そして、上記側板投入完了釦３２ａが押されると、側板搬送路２０に進行方向に間隔を隔てて載置された左右の側板１が図４の矢印方向から接着剤塗布部３３側に搬送される。この場合、進行方向の前方側に位置する側板１（実施形態では左の側板１）が塗布用後ベルトコンベア３４ｂと塗布用前ベルトコンベア３４ａとの間を通過すると、検知手段によりこれを検知し、塗布用後ベルトコンベア３４ｂと塗布用前ベルトコンベア３４ａとの間に位置している中間ストッパ３５ａが上昇して後続する別の側板１（実施形態では右の側板１）が塗布用前ベルトコンベア３４ａに進入しないようにする。
【００２７】
塗布用前ベルトコンベア３４ａに進入した方の側板１が塗布用前ベルトコンベア３４ａの終端部付近に位置する接着位置決め用第１ストッパ３５ｂに当たると、塗布用前ベルトコンベア３４ａを停止し、複数列の塗布用前ベルトコンベア３４ａ間に配置している持ち上げ手段（図示せず）を上昇して上記側板１を上方に持ち上げ、第１位置決め用押圧部３５ｃにより該側板１を接着位置決め用第２ストッパ３５ｄに押し当てて該側板１の位置決めを行う。また、塗布用後ベルトコンベア３４ｂに進入した後続する側板１が図４の矢印方向から側板搬送路２０と塗布用後ベルトコンベア３４ｂの間の接着位置決め用第３ストッパ３５ｅの上方を通過すると、検知手段によりこれを検知して塗布用後ベルトコンベア３４ｂが一旦停止すると共に接着位置決め用第３ストッパ３５ｅが上昇し、次に塗布用後ベルトコンベア３４ｂが逆転して後続する上記側板１を塗布用後ベルトコンベア３４ｂに押し当て塗布用後ベルトコンベア３４ｂが停止する。次に、複数列の塗布用後ベルトコンベア３４ｂ間に配置している持ち上げ手段（図示せず）を上昇して上記側板１を上方に持ち上げ、第２位置決め用押圧部３５ｆにより該側板１を接着位置決め用第２ストッパ３５ｄに押し当てて該側板１の位置決めを行う。
【００２８】
このように、左右一対の側板１を接着剤塗布部３３の所定位置に位置決めした状態で、接着剤塗布部３３に設けた接着剤塗布装置３６により左右の側板１の内面（接着剤塗布部３３においては内面上側を向いている）に設けた嵌合孔２７に接着剤を塗布する。接着剤塗布装置３６はＸ−Ｙ−Ｙ型サーボスライダを備えていて、入力部１９で入力した組み立てようとする箱体の側板１のあらかじめ登録してある嵌合孔２７位置のデータに基づいて制御部の制御により自動的に移動して各側板１の各嵌合孔２７内に接着剤を正確に塗布するものである。
【００２９】
天板・地板搬送路２１は図５に示すようなもので、この天板・地板搬送路２１にはウオール用箱体７の場合には天板３と地板４とが供給され、フロアー用箱体１０の場合には地板４のみが供給される。この天板・地板搬送路２１は進行方向に第１天板・地板搬送路２１ａ、第２天板・地板搬送路２１ｂ、第３天板・地板搬送路２１ｃ、第４天板・地板搬送路２１ｄを配置して構成してあり、第１天板・地板搬送路２１ａには天板３、地板４の左右方向の寸法を検知するための寸法検知手段３０ｂが設けてあって、第１天板・地板搬送路２１ａに供給された天板３、地板４左右方向の寸法を検知するようになっている。図６に示す実施形態においては、第１天板・地板搬送路２１ａがローラコンベアにより構成してあり、第１天板・地板搬送路２１ａの搬送方向の２箇所においてローラコンベア間に巾方向にわたってそれぞれ寸法検知手段３０ｂを構成する複数のリミットスイッチ３１ｂが設けてあり、天板３又は地板４を第１天板・地板搬送路２１ａに載置して天板３又は地板４をＬ状をしたストッパ３７に当てて位置決めした状態で、上記リミットスイッチ３１ｂにより天板３又は地板４の寸法を検出するようになっている。そして、このようにして検出された寸法情報が前述の入力部１９で入力された組み立てようとする箱体の種類の情報で特定された天板３又は地板４の寸法と同じであるか否かが制御部に設けた判定手段により判定され、検出した寸法が入力部１９で入力した組み立てようとする箱体の天板３又は地板４のあらかじめ登録してある寸法と異なる場合には、警告ランプや警告ブザー等の警告手段（図示せず）が動作して、当該箱の組み立ては中止される。
【００３０】
上記のような寸法検知手段３０ｂを備えた第１天板・地板搬送路２１ａには組み立てるべき箱体がウオール用箱体７の場合には天板３、地板４を供給するものあり、フロアー用箱体１０の場合には地板４のみを供給するものである。天板３や地板４を供給するに当たっては内面が上となるように第１天板・地板搬送路２１ａに載置される。
【００３１】
まず、組み立てるべき箱体がウオール用箱体７の場合を例に説明する。この場合、天板３、地板４の２部材を供給するのであるが、天板３を第１天板・地板搬送路２１ａに供給して寸法判定を行った後、送り釦３２ｂを押す。送り釦３２ｂを押すと、天板３が第１天板・地板搬送路２１ａから第２天板・地板搬送路２１ｂに送られる。次に、地板４を第１天板・地板搬送路２１ａに供給して寸法判定を行う。
【００３２】
そして、スタート釦３２ｃを押すことで第２天板・地板搬送路２１ｂに位置している天板３が第３天板・地板搬送路２１ｃを経て第４天板・地板搬送路２１ｄに送られ、第１天板・地板搬送路２１ａに位置している地板４が第３天板・地板搬送路２１ｃに行われる。
【００３３】
なお、上記スタート釦３２ｃを押すのは後述のように組み立てるべき箱体のワンセット分の全ての材料の供給を各搬送路に供給完了した後に行うものである。つまり、前述の両側板１を側板搬送路２０に供給して側板投入完了釦３２ａを押し、更に、天板３、地板４を第１天板・地板搬送路２１ａに供給して送り釦３２ｂを押し、更に、後述の天前桟・天後桟搬送路２２に天前桟８、天後桟９を供給し（天前桟・天後桟搬送路２２への天前桟８、天後桟９の供給はフロアー用箱体１０を組み立てるときのみ）、裏板搬送路１６に裏板５を供給し、裏桟搬送路２３に裏桟６を供給する（裏桟搬送路２３に裏桟６への供給はウオール用箱体７を組み立てるときのみ）という組み立てるべき箱体のワンセット分の材料すべてを各搬送路に供給し終わってからスタート釦３２ｃを押す。
【００３４】
第３天板・地板搬送路２１ｃの側方には図１、図７乃至図９に示すように回動自在に地板反転装置３８が配設してあり、地板反転装置３８には下面部が櫛状部３８ａとなったコ字状をした側受け部３８ｂと、側受け部３８ｂの前端部から直角に突出している断面Ｌ状をした前受け部３８ｃと、前受け部３８ｃに取付けられた移動自在なクランプ部３８ｄとで構成してあり、天板３が第３天板・地板搬送路２１ｃを通過する時は地板反転装置３８は第３天板・地板搬送路２１ｃ上を移動する天板３に当たらない位置に待機しておき、天板３が第３天板・地板搬送路２１ｃを通過したのを検知手段により検知すると、図８のようにローラコンベアで構成した第３天板・地板搬送路２１ｃのローラコンベア間に櫛状部３８ａ、前受け部３８ｂの横片が位置するように地板反転装置３８を移動するように制御するものであり、このため、地板４が第３天板・地板搬送路２１ｃに搬送されると前受け部３８ｂの縦片に当たって止まり、この状態で地板反転装置３８を図９のように回動（例えば１３５°回動）して地板４を反転すると共にクランプ部３８ｄを駆動して地板４の反転状態を保持するようになっている。この反転状態において地板４は外面側が上面側となるようになっている。
【００３５】
次に、天前桟・天後桟搬送路２２につき説明する。図１０に示すように、天前桟・天後桟搬送路２２には組み立てようとする箱がフロアー用箱体１０の時にのみ天前桟８、天後桟９を供給するものであり、ウオール用箱体７の時には使用しない。この、天前桟・天後桟搬送路２２にはリミットスイッチ３１ｃよりなる寸法検知手段３０ｃが設けてあって、天前桟・天後桟搬送路２２に供給された天前桟８、天後桟９の長さ方向の寸法を検知するようになっている。そして、このようにして検出された寸法情報が前述の入力部１９で入力された組み立てようとする箱体の種類の情報で特定された天前桟８、天後桟９の寸法と同じであるか否かが制御部に設けた判定手段により判定され、検出した寸法が入力部１９で入力した組み立てようとする箱体の天前桟８、天後桟９のあらかじめ登録してある寸法と異なる場合には、警告ランプや警告ブザー等の警告手段（図示せず）が動作して、当該箱の組み立ては中止される。
【００３６】
次に、図１１乃至図１６に基づいて裏板搬送路１６、裏桟搬送路２３につき説明する。図１１に示すように、裏板搬送路１６の下方には裏桟搬送路２３が平行して配置してあり、裏板搬送路１６の始端部に裏桟投入用開口３９が設けてある。裏桟搬送路２３は図１５に示すように２列設けてあり、それぞれ裏桟６を１本ずつ裏桟投入用開口３９から投入して載置するようになっている。裏桟搬送路２３への裏桟６の供給はウオール用箱体７を組み立てる場合のみであり、フロアー用箱体１０の場合は供給しない。この、裏桟搬送路２３の始端部には図１５（ｂ）に示すように、リミットスイッチ３１ｄよりなる寸法検知手段３０ｄが設けてあって、裏桟搬送路２３に供給された裏桟６の長さ方向の寸法を検知するようになっている。そして、このようにして検出された寸法情報が前述の入力部１９で入力された組み立てようとする箱体の種類の情報で特定された裏桟６の寸法と同じであるか否かが制御部に設けた判定手段により判定され、検出した寸法が入力部１９で入力した組み立てようとする箱体の裏桟６のあらかじめ登録してある寸法と異なる場合には、警告ランプや警告ブザー等の警告手段（図示せず）が動作して、当該箱の組み立ては中止される。
【００３７】
図１６のように、裏桟搬送路２３の終端部のすぐ手前には裏桟６の内面（裏桟６が裏桟搬送路２３を搬送される場合にはこの内面が上となるようにして搬送される）に接着剤を塗布するための接着剤塗布装置７５が設けてあり、裏桟搬送路２３の終端部の側方には裏桟反転装置７６が設けてある。裏桟反転装置７６はロータリーアクチュエータ７６ａにより回動自在となっており、また、裏桟反転装置７６にはクランプ装置７６ｂが設けてある。そして、裏桟搬送路２３を送られてきた裏桟６の内面に接着剤が塗布され、裏桟搬送路２３の終端のストッパ２３ａに当たって位置決めされて停止した状態で、裏桟反転装置７６が回動して裏桟６の上方に位置し、クランプ装置７６ｂにより裏桟６をクランプし、このクランプ状態で裏桟反転装置７６を１８０°回転して裏桟６を上下反転した状態で保持する（この上下反転状態で裏桟６の内面の接着剤を塗布した部分が下側となる）ようになっている。
【００３８】
裏板搬送路１６の始端部には図１２に示すように、Ｌ状をした位置決め部材６８が設けてあり、また、リミットスイッチ３１ｅよりなる寸法検知手段３０ｅが設けてある。そして、裏板搬送路１６の始端部に裏板５を載置してＬ状をした位置決め部材６８に２辺を当てることで位置決めした状態で寸法検知手段３０ｅにより裏板５の左右方向と高さ方向の寸法を検出するようになっている。そして、このようにして検出された寸法情報が前述の入力部１９で入力された組み立てようとする箱体の種類の情報で特定された裏板５の寸法と同じであるか否かが制御部に設けた判定手段により判定され、検出した寸法が入力部１９で入力した組み立てようとする箱体の裏板５のあらかじめ登録してある寸法と異なる場合には、警告ランプや警告ブザー等の警告手段（図示せず）が動作して、当該箱の組み立ては中止される。
【００３９】
裏板搬送路１６の途中には図１３、図１４に示すように、第１の裏板移動手段１４ａの一部を構成する裏板選択取り上げ手段１７が設けてある。裏板移動手段１４ａの裏板選択取り上げ手段１７部分以外の構造は後で説明する。裏板選択取り上げ手段１７は、ローラコンベアよりなる裏板搬送路１６の途中の上方位置において水平に倒れた姿勢と垂直に起立した姿勢との２位置に起倒自在な回動体１７ａと、該回動体１７ａの起立姿勢における下端部に設けた受け溝１７ｂと、回動体１７ａの起立姿勢における下端部側に移動自在（受け溝１７ｂ側に向けて接近する方向及び離反する方向に移動自在）な移動爪１７ｃと、移動爪１７ｃを移動するためのシリンダ装置１７ｄと、裏板搬送路１６を構成するローラ間に配置された多数の突部１７ｅを有する上下移動自在なリフタ１７ｆ（回動体１７ａを水平に倒した姿勢で該回動体１７ａの下方に位置している）と、リフタ１７ｆよりも前方においてローラ間に配置したストッパ１７ｇとで構成してある。
【００４０】
入力部１９で入力された組み立てようとする箱に関する情報に基づき組み立てるべき箱がフロアー用箱体１０である場合にはストッパ１７ｇ、リフタ１７ｆが下降しており、裏板搬送路１６を搬送される裏板５は回動体１７ａの下方を通過して裏板搬送路１６の終端部まで搬送されるようになっている。
【００４１】
一方、入力部１９で入力された組み立てようとする箱に関する情報に基づき組み立てるべき箱がウオール用箱体７である場合にはストッパ１７ｇがローラ間からローラよりも上方に突出するように制御部からの指令により動作し、裏板搬送路１６を搬送される裏板５がストッパ１７ｇに当たるので、その後、リフタ１７ｆが上昇して多数の突部１７ｅにより裏板５を上方に持ち上げるように動作する。裏板５を持ち上げると移動爪１７ｃが突部１７ｅ間を移動し、移動爪１７ｃ内に裏板５の後端をはめ込んだ状態で裏板５を押して裏板５の前端を受け溝１７ｂに押し込んで停止する。その後、裏板５を保持した状態で回動体１７ａが９０°回転して裏板５を垂直に起立させるようになっている。
【００４２】
プレス手段１２としては添付図面に示す実施形態においては第１のプレス手段１２ａと第２のプレス手段１２ｂとがある。
【００４３】
まず第１のプレス手段１２ａにつき説明する。第１のプレス手段１２ａには図１７、図１８に示すように左右に対向する移動プレス盤４０ａ、４０ｂが設けてある。両移動プレス盤４０ａ、４０ｂの対向面には図１９に示すように吸着パッド４２が設けてある。両移動プレス盤４０ａ、４０ｂのうち裏板搬送路１６の側方に位置する一方の移動プレス盤４０ａは裏板搬送路１６と直交する方向及び平行な方向の２方向に移動自在となっている。すなわち、図１７、図１８に示すように、基体６９上に設けた基台４３ａに対して移動基台４４がガイドレール４５ａをガイドとしてシリンダ装置４１ａにより裏板搬送路１６と直交する方向に移動自在となっており、また、移動基台４４に対して一方の移動プレス盤４０ａがガイドレール４５ｃをガイドとしてシリンダ装置４１ｃにより裏板搬送路１６と平行な方向に移動自在となっている。また、両移動プレス盤４０ａ、４０ｂのうち他方の移動プレス盤４０ｂは裏板搬送路１６と直交する方向に移動自在となっている。すなわち、図１７、図１８に示すように、基台４３ｂに対して移動プレス盤４０ｂがガイドレール４５ｂをガイドとしてシリンダ装置４１ｂにより裏板搬送路１６と直交する方向に移動自在となっている。したがって、シリンダ装置４１ｃを駆動することで移動プレス盤４０ａを移動プレス盤４０ｂに対して裏板搬送路１６と平行する方向に移動でき、また、シリンダ装置４１ａ、シリンダ装置４１ｂを駆動することで、対向する移動プレス盤４０ａ、４０ｂを互いに近づく方向、離れる方向に移動することができるようになっている。
【００４４】
また、図１８に示すように、基台４３ｂは基体６９に設けたガイドレール４３ｃに対して裏板搬送路１６と直交する方向（つまり左右方向）に移動自在となっており、サーボモータ４３ｄにより正転、逆転するボールねじ４３ｅが基台４３ｂに螺合してあり、サーボモータ４３ｄを駆動することで基台４３ｂを移動し、これにより組み立てようとする箱体の左右巾に応じて基台４３ｂを移動するようになっている。
【００４５】
図１８、図１９に示すように、移動プレス盤４０ａ及び移動プレス盤４０ｂには対向面の下方にはプレス内天板搬入コンベア４６が設けてある。また、移動基台４４上のプレス内天板搬入コンベア４６よりも下方で且つ移動プレス盤４０ｂよりも他方の移動プレス盤４０ａ側にずれた位置と、移動プレス盤４０ｂのプレス内天板搬入コンベア４６よりも下方で且つ裏板搬送路１６側にずれた位置にそれぞれ、天板吸着治具４７と、天前桟吸着治具４８と、天後桟吸着治具４９とが設けてある。ここで図１９に示すように、天板吸着治具４７は天前桟吸着治具４８の前方に配置し、天後桟吸着治具４９は天前桟吸着治具４８の後方に配置してある。上記天板吸着治具４７、天前桟吸着治具４８、天後桟吸着治具４９はそれぞれシリンダ４７ａ、４８ａ、４９ａにより上下移動自在となっている。天前桟吸着治具４８はＬ状をしていて垂直面と水平面との両面にそれぞれ吸着部が設けてある。
【００４６】
移動プレス盤４０ａ及び移動プレス盤４０ｂには前端部に図１９に示すようにシリンダ装置５１ａにより左右方向に移動自在な側板位置決め部材５１ｂが設けてあって移動プレス盤４０ａ及び移動プレス盤４０ｂの対向面の前端において対向面より突出自在となっている。また、移動プレス盤４０ａ及び移動プレス盤４０ｂの下端部には側板位置決め用突部５１ｃが設けてある。
【００４７】
また、側板位置決め用突部５１ｃよりも下方にはシリンダ装置５２ａにより移動自在な天板位置決め部材５２ｂが設けてある。
【００４８】
移動プレス盤４０ａの前端部には図１８、図２０、図２１に示すように、上下端部から裏板搬送路１６側に向けて上下の裏板搬入ガイド５０が設けてあり、この上下の裏板搬入ガイド５０には上下に対向する対向面に断面略Ｕ状をしたガイド溝が形成してある。また、裏板搬入ガイド５０には爪５０ａを有する搬入用チェーン５０ｂが設けてあり、該搬入用チェーン５０ｂはモータにより回転駆動するようになっている。
【００４９】
上下の裏板搬入ガイド５０のガイド溝の裏板搬送路１６の端部は、裏板５を保持して垂直に起立した回動体１７ａの受け溝１７ｂ、移動爪１７ｃ内とそれぞれ対向するような位置関係となっており、回動体１７ａに設けたロータリーアクチュエータ１７ｈにより垂直姿勢に保持している裏板５を裏板押し装置８０によって押して上下の裏板搬入ガイド５０のガイド溝内に嵌め込むようになっている。そして、上下の裏板搬入ガイド５０のガイド溝内にはめこまれた裏板５は搬入用チェーン５０ｂを駆動することで爪５０ａにより押されて対向する移動プレス盤４０ａ、４０ｂ間に進入するようになっている。
【００５０】
裏板移動手段１４ａはこれらロータリーアクチュエータ１７ｈ、上下の裏板搬入ガイド５０、爪５０ａ付きの搬入用チェーン５０ｂと、前記した裏板選択取り上げ手段１７と、裏板押し装置８０とで構成してある。
【００５１】
次に、第２のプレス手段１２ｂにつき説明する。第２のプレス手段１２ｂには図２２に示すように左右に対向する移動プレス盤５４ａ、５４ｂが設けてあり、両移動プレス盤５４ａ、５４ｂの間の下部の両側にベルトコンベア５８ａ、５８ｂが配置してある。両移動プレス盤５４ａ、５４ｂは互いに近づいたり、離れたりする方向にシリンダ装置５５ａ、５５ｂにより移動自在となっている。すなわち、図２２、図２３に示すように、基体６９上に設けたガイドレール５６ａをガイドとして移動プレス盤５４ａがシリンダ装置５５ａにより仮組みされた箱体の移送方向と直交する方向に移動自在となっている。また、基体６９上に設けたガイドレール５６ｂをガイドとして移動基台５９ａが移動自在となっており、サーボモータ５９ｂにより正転、逆転するボールねじ５９ｃが移動基台５９ａに螺合してあり、サーボモータ５９ｂを駆動することで移動基台５９ａを移動し、これにより組み立てようとする箱体の左右巾に応じて移動基台５９ａを仮組みされた箱体の移送方向と直交する方向に移動するようになっている。移動基台５９ａに設けたガイドレール５９ｄをガイドとして他方の移動プレス盤５４ｂがシリンダ装置５５ｂにより仮組みされた箱体の移送方向と直交する方向に移動自在となっている。一対のベルトコンベア５８ａ、５８ｂのうち一方のベルトコンベア５８ａは基体６９に固定してあり、他方のベルトコンベア５８ｂはその下部の支持部がガイドレール５６ｂをガイドとして移動自在となっており、該支持部に上記ボールねじ５９ｃが螺合してあり、サーボモータ５９ｂを駆動することで移動基台５９ａと同調して移動するようになっている。また、両ベルトコンベア５８ａ、５８ｂは昇降シリンダ装置６０ａ、６０ｂにより上下移動自在となっている。
【００５２】
移動プレス盤５４ａ及び移動プレス盤５４ｂには前端部に図２２示すようにシリンダ装置６１ａにより左右方向に移動自在な仮組み箱位置決め部材６１ｂが設けてあって移動プレス盤５４ａ及び移動プレス盤５４ｂの対向面の前端において対向面より突出自在となっている。また、移動プレス盤５４ａ及び移動プレス盤５４ｂの対向面にはそれぞれ図２３に示すように前後方向（仮組みした箱体の搬送方向）に移動自在な奥行き位置決め治具６２が設けてある。更に、移動プレス盤５４ａ及び移動プレス盤５４ｂには前端部の上部に上方程開口巾が広くなった略逆ハ字状をした通路溝よりなる裏板挿入ガイド６３が設けてある。
【００５３】
第２のプレス手段１２ｂの前方には図１に示すように箱体搬出路５３が設けてあり、組み立てが完了した箱体を箱体搬出路５３から搬出するようになっている。
【００５４】
図１に示すように、接着剤塗布部３３と天板・地板搬送路２１と第１のプレス手段１２ａとで囲まれた部分には多関節アーム７０ａを有する第１の多関節ロボット７０が配設してあり、多関節アーム７０ａの先端部には図２４に示すように吸盤部７０ｂが設けてある。この第１の多関節ロボット７０は接着剤塗布部３３において嵌合孔２７に接着剤を塗布された両側板１をそれぞれ１つずつ吸着してそれぞれ左右の移動プレス盤４０ａ、４０ｂの吸着パッド４２位置まで運んで移動プレス盤４０ａ、４０ｂの吸着パッド４２に吸着させた後に側板１の吸着を解除し、また、地板反転装置３８で反転した地板４を吸着して両移動プレス盤４０ａ、４０ｂ間の上部に移動して所定位置に保持し、この保持状態を後述の仮組み状態となるまで維持するようになっている。
【００５５】
また、裏桟搬送路２３の終端部と第２のプレス手段１２ｂと箱体搬出路５３とに囲まれた部分には図１に示すように多関節アーム７１ａを有する第２の多関節ロボット７１が配設してあり、多関節アーム７１ａの先端部には図２５に示すように吸盤部７１ｂとタッカー釘打ち装置のような固着具打ち込み装置７１ｃが設けてある。この第２の多関節ロボット７１は後述のフロアー用箱体１０の組み立て時に第１のプレス手段１２ａで仮組みした箱体に裏桟６付きの裏板５を吸着して嵌め込み溝２ａ、２ｄに嵌め込むことを行い、また、後述のウオール用箱体７の組み立て時に第１のプレス手段１２ａで仮組みした箱体が第２のプレス手段１２ｂ内に送られた場合に、裏桟搬送路２３の終端部に供給された裏桟６を吸着して該箱体の裏板５の上下に移動して位置決めして固着具を打設して固着することを行うようになっている。
【００５６】
以下、上記のような共通の組み立てライン１１によりウオール用箱体７、フロアー用箱体１０を組み立てる方法につき説明する。
【００５７】
まず、ウオール用箱体７の組み立てにつき説明する。材料供給ライン２６からウオール用箱体７の材料のワンセットが作業台２４で供給されると、バーコード読み取り装置２５により共通の組み立てライン１１に供給して組み立てようとするウオール用箱体７に関する情報が読み取られて制御部に入力される。
【００５８】
その後、作業台２４に供給されたワンセット分のウオール用箱体７の材料を作業者の人力又は材料供給ロボットによりそれぞれの材料を搬送する該当する各搬送路の始端部に供給する。
【００５９】
すなわち、一対の側板１を側板搬送路２０の始端部に供給して側板投入完了釦３２ａを押す。
【００６０】
また、天板・地板搬送路２１に、天板３を供給し、送り釦３２ｂを押して天板３を第１天板・地板搬送路２１ａから第２天板・地板搬送路２１ｂに送り、次に、地板４を第１天板・地板搬送路２１ａに供給する。
【００６１】
また、裏桟搬送路２３に２本の裏桟６を供給し、また、裏板搬送路１６に裏板５を供給する。
【００６２】
このようにして組み立てようとするウオール用箱体７のワンセット分の材料をそれぞれの材料を搬送する該当する各搬送路の始端部への供給が完了すると、スタート釦３２ｃを押す。
【００６３】
スタート釦３２ｃを押すと、前述のように一対の側板１を接着剤塗布部３３側に送り、接着剤塗布装置３６により左右の側板１の内面に設けた嵌合孔２７に接着剤を塗布する。この場合、既に側板投入完了釦３２ａを押しているとスタート釦３２ｃを押す前であっても側板１が前述のように接着剤塗布部３３に送られて接着剤が塗布される。
【００６４】
また、スタート釦３２ｃを押すことで、前述のように第２天板・地板搬送路２１ｂに送られていた天板３を第４天板・地板搬送路２１ｄに送り、第１天板・地板搬送路２１ａに供給されている地板４を第３天板・地板搬送路２１ｃに送って地板反転装置３８で地板４を反転させて反転状態を保持させる。
【００６５】
また、スタート釦３２ｃを押すことで、前述のように裏桟搬送路２３の始端部に供給された２本の裏桟６が裏桟搬送路２３の終端部まで送られる。
【００６６】
また、スタート釦３２ｃを押すことで、前述のように裏板搬送路１６の始端部に供給された裏板５が搬送され、この時、ストッパ１７ｇがローラ間からローラよりも上方に突出しており、裏板搬送路１６を搬送される裏板５がストッパ１７ｇに当たり、次に、リフタ１７ｆが上昇して多数の突部１７ｅにより裏板５を上方に持ち上げ、移動爪１７ｃが突部１７ｅ間を移動し、移動爪１７ｃ内に裏板５の後端をはめ込んだ状態で裏板５を押して裏板５の前端を受け溝１７ｂに押し込んで停止し、その後、裏板５を保持した状態で回動体１７ａが９０°回転して裏板５を垂直に起立させる。
【００６７】
この段階で第１のプレス手段１２ａは開いており（つまり移動プレス盤４０ａ、４０ｂが対向面間の距離が完成後の該当するウオール用箱体７の左右の側板１間の距離よりも長くなるように開いており）、また、移動プレス盤４０ａは移動プレス盤４０ｂよりも後方側にずれるように後退しており、また、両側の側板位置決め部材５１ｂが第１のプレス手段１２ａの前端部においてプレス内に突出しており、また、天後桟吸着治具４９が上昇しており、天板吸着治具４７が下降している。
【００６８】
前述のように第４天板・地板搬送路２１ｄに送られた天板３は上記のように第１のプレス手段１２ａが開いているとプレス内天板搬入コンベア４６に送られ所定位置で位置決めされて停止し（この場合、天後桟吸着治具４９が上昇していて天板３が当たって所定位置で停止することで前後方向の位置決めをする）、次に、シリンダ装置５２ａにより天板位置決め部材５２ｂを移動させて天板３の巾方向（左右方向）の位置決めを行う。このように天板３をプレス内において前後、左右の位置決めをした後、天板吸着治具４７が上昇して天板３の外面を吸着した状態で所定位置まで持ち上げて保持する。
【００６９】
第１の多関節ロボット７０は上記のように両側板１の嵌合孔２７への接着剤の塗布が完了し且つ第１のプレス手段１２ａが開いていると左右両側板１をそれぞれ１つずつ順に吸着して（内面を吸着して）移動し、それぞれ移動プレス盤４０ａ、４０ｂの各吸着パッド４２に押し付け、吸着パッド４２により側板１を吸着すると第１の多関節ロボット７０による吸着を解除する。このようにして、左右の側板１をそれぞれ移動プレス盤４０ａ、４０ｂの所定位置に吸着する。この場合、側板位置決め部材５１ｂと側板位置決め用突部５１ｃをそれぞれ側板１の２辺の位置決め基準として第１の多関節ロボット７０により移動プレス盤４０ａ、４０ｂに対する側板１の位置決めをして上記のように移動プレス盤４０ａ、４０ｂの各吸着パッド４２に吸着保持させるものである。
【００７０】
次に、第１の多関節ロボット７０が地板反転装置３８に反転した状態で保持されている地板４の外面を吸着して移動対向する移動プレス盤４０ａ、４０ｂ間の上部に移動し、上記天板吸着治具４７により所定位置に吸着保持されている天板３の上方位置に天板３と組み立て完成後における天板３と地板４との距離と同じ距離を隔てて位置させた状態で保持する。ここで、ウオール用箱体７の組み立てに当たっては、天板吸着治具４７と第１の多関節ロボット７０の吸盤部７０ｂとで天板３と地板４とを上下に所定間隔を隔てて保持する保持手段１３を構成している。
【００７１】
上記のように、開いた移動プレス盤４０ａ、４０ｂ間の下部と上部に天板３と地板４とを配置した状態で天板３と地板４は上記のように組み立て完成後に天板３と地板４との距離と同じ距離を隔てて上下に対向していると共に、天板３と地板４の嵌め込み溝２ｂ、２ｃを上下に対向している。また、上記のように移動プレス盤４０ａ、４０ｂで左右両側板１が対向するように保持した状態で、両側板１は組み立て完成後の両側板１間の距離よりも長い距離を隔てており、且つ、裏板搬送路１６側に近い方に保持されている側板１が他の側板１よりも後方にずれた位置に保持されており、この場合、後方にずれた側板１の後端面（ラインの流れ方向においては前方側の端面）が他の側板１の嵌め込み溝２ａの開口部の前端縁（ラインの流れ方向においては後方側の端縁）よりラインの流れ方向において後方に位置するようにずれている。
【００７２】
次に、回動体１７ａに垂直に起立させられている裏板５をロータリーアクチュエータ１７ｈにより上下の裏板搬入ガイド５０に移動し、上下の裏板搬入ガイド５０に移動した裏板５を搬入用チェーン５０ｂを駆動することで爪５０ａにより移動して、保持手段１３により保持している上下に対向する地板４と天板３との嵌め込み溝２ｂ、２ｃに裏板５の上下両端部を図２７（ａ）、図２８のように嵌め込み、その後、図２７（ｂ）のようにシリンダ装置４１ｃにより一方の移動プレス盤４０ａをガイドレール４５ｃをガイドとして前方側に移動して移動プレス盤４０ａ、４０ｂに保持している左右両側板１の嵌め込み溝２ａを左右方向に対向させ、次に、図２７（ｃ）のようにシリンダ装置４１ａ、４１ｂにより左右の移動プレス盤４０ａ、４０ｂを互いに近づく方向に移動し、移動プレス盤４０ａ、４０ｂに保持している左右両側板１の内面の上下両端部に設けた接着剤を塗布した嵌合孔２７を天板３、地板４の両側端面に突設した嵌合突部２８ａ、２８ｂに嵌め込むのであるが、この場合、嵌合突部２８ａと嵌合孔２７とで構成する嵌合部１５及び嵌合突部２８ｂと嵌合孔２７とで構成する嵌合部１５の各嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みすると共に、両側板１の嵌め込み溝２ａを裏板５の対向する左右の一対の辺に嵌め込むものである。上記のようにして第１のプレス手段１２ａによるプレスでウオール用箱体７を仮組みするのであるが、この場合、両側板１間の距離は完成後のウオール用箱体７の両側板１間の距離より若干短い状態となるように仮組みするものであり、したがって、この段階では両側板１の内面と天板３、地板４の各両側端面とは当接しておらず１ｍｍ程度の小間隙が存在するようにしてある（上記未嵌め込み部の長さはこの小間隙と同じ長さと同じである）。
【００７３】
上記のようにウオール用箱体７の仮組みが終わると、シリンダ装置４１ａ、４１ｂにより移動プレス盤４０ａ、４０ｂが互いに離れるように移動する（図２７（ｄ）参照）ことで第１のプレス手段１２ａを開き、第１の多関節ロボット７０の吸盤部による地板４の吸着を止め、天板吸着治具４７による吸着を止めると共に天板吸着治具４７を下降させて仮組み状態のウオール用箱体７をプレス内天板搬入コンベア４６に載せ、プレス内天板搬入コンベア４６を駆動して仮組み状態のウオール用箱体７を第２のプレス手段１２ｂ内のベルトコンベア５８ａ、５８ｂに送り込む。
【００７４】
この場合、第２のプレス手段１２は開いていて第１のプレス手段１２ａにより仮組みしたウオール用箱体７を第２のプレス盤４０ｂ内のベルトコンベア５８ａ、５８ｂに移送した際に移送されるウオール用箱体７が奥行き位置決め治具６２に当たらないようになっている。また、両側の仮組み箱位置決め部材６１ｂが両移動プレス盤５４ａ、５４ｂ間内に突出している。
【００７５】
ベルトコンベア５８ａ、５８ｂに移送された仮組みされたウオール用箱体７は仮組み箱位置決め部材６１ｂに当たるので、この段階でベルトコンベア５８ａ、５８ｂが停止し、その後、仮組み箱位置決め部材６１ｂが移動して仮組み状態のウオール用箱体７に当接して左右方向の位置決めをし、また、移動プレス盤５４ａ、５４ｂを互いに近づく方向に移動して仮組み状態のウオール用箱体７の両側板１に当接して、仮組み状態のウオール用箱体７の巾方向（左右方向）の位置決めを行い、また、奥行き位置決め治具６２が前方に移動して仮組み状態のウオール用箱体７に当接して前後方向の位置決めをして保持する。
【００７６】
次に、第２の多関節ロボット７１の吸盤部７１ｂにより裏桟搬送路２３の終端部に供給されて接着剤が塗布され、裏桟反転装置７６により反転保持された裏桟６を吸着し（裏桟反転装置７６で反転保持されている裏桟６の上面の接着剤が塗布してない面を吸盤部７１ｂで吸着し）て該箱体の裏板５の上下に移動して裏板５と天板３の後端とのなすコーナ部及び裏板５と地板４の後端とのなすコーナ部に運んで図２９のように各コーナ部に押し当てて位置決めすると共にタッカー釘打ち装置のような固着具打ち込み装置７１ｃによりタッカー釘のような固着具７３を裏板５から天板３にかけて打ち込むと共に裏板５から地板４にかけて打ち込むものである。この場合、ベルトコンベア５８ａ、５８ｂを下方に下げた状態で上記固着具７３の打ち込みを行うものである。
【００７７】
次に、移動プレス盤５４ａ、５４ｂを互いに近づく方向に移動し、仮組み状態のウオール用箱体７の両側板１を押圧プレスして両側板１の内面を天板３、地板４それぞれの両側端面に圧接すると共に仮組み段階で嵌め込み方向に未嵌合部を残していた嵌合部１５の未嵌合部を嵌め込み方向に完全に嵌合する。
【００７８】
次に、多関節ロボット７０の固着具打ち込み装置７１ｃにより図３０のように側板１と天板３、側板１と地板４、側板１と裏板５、天板３と裏桟６、地板４と裏桟６をそれぞれ接合するようにタッカー釘のような固着具７３を打ち込み本組み立て状態で各部材同士を固着する。
【００７９】
このようにして本組み立てが完了すると、固着具７３の打ち込みの際に下降していたベルトコンベア５８ａ、５８ｂを上昇させて組み立てが完成したウオール用箱体７の下面に当て、移動プレス盤５４ａ、５４ｂが互いに離れる方向に移動して第２のプレス手段１２ｂを開き、仮組み箱位置決め部材６１ｂを後退させ、ベルトコンベア５８ａ、５８ｂを駆動して組み立て完了したウオール用箱体７を箱体搬出路５３に送って搬出するものである。
【００８０】
ここで、仮組み立て、本組み立ての各段階においてウオール用箱体７は天板３が下となるように本来の使用状態とは上下逆の姿勢となるようにしてあるが、これはウオール用箱体７の天板３はコンベア等に載置されて仮に傷がついても施工状態では外部に見えない処なので問題はないが、地板４は施工状態では外部に露出して見えるので、地板４の下面がコンベア等に当たって傷付かないようにしてある。
【００８１】
次に、フロアー用箱体１０の組み立てにつき説明する。材料供給ライン２６からフロアー用箱体１０の材料のワンセットが作業台２４で供給されると、バーコード読み取り装置２５により共通の組み立てライン１１に供給して組み立てようとするフロアー用箱体１０に関する情報が読み取られて制御部に入力される。
【００８２】
その後、作業台２４に供給されたワンセット分のフロアー用箱体１０の材料を作業者の人力又は材料供給ロボットによりそれぞれの材料を搬送する該当する各搬送路の始端部に供給する。
【００８３】
すなわち、一対の側板１を側板搬送路２０の始端部に供給して側板投入完了釦３２ａを押す。
【００８４】
また、天板・地板搬送路２１に地板４のみを供給する。
【００８５】
また、天前桟・天後桟搬送路２２に天前桟８、天後桟９を供給する。
【００８６】
また、裏板搬送路１６に裏桟６があらかじめ付けられた裏板５を供給する。
【００８７】
なお、フロアー用箱体１０の組立の場合には裏桟搬送路２３には裏桟を供給しない。
【００８８】
このようにして組み立てようとするフロアー用箱体１０のワンセット分の材料をそれぞれの材料を搬送する該当する各搬送路の始端部への供給が完了すると、スタート釦３２ｃを押す。
【００８９】
スタート釦３２ｃを押すと、前述のように一対の側板１を接着剤塗布部３３側に送り、接着剤塗布装置３６により左右の側板１の内面に設けた嵌合孔２７に接着剤を塗布する。この場合、既に側板投入完了釦３２ａを押しているとスタート釦３２ｃを押す前であっても側板１が前述のように接着剤塗布部３３に送られて接着剤が塗布される。
【００９０】
また、スタート釦３２ｃを押すことで、前述のように第１天板・地板搬送路２１ａに供給されている地板４を第３天板・地板搬送路２１ｃに送って地板反転装置３８で地板４を反転させて反転状態を保持させる。
また、スタート釦３２ｃを押すことで、天前桟・天後桟搬送路２２に供給された天前桟８、天後桟９がそれぞれ天前桟・天後桟搬送路２２の終端部に搬送される。
【００９１】
また、スタート釦３２ｃを押すことで、前述のように裏板搬送路１６の始端部に供給された裏板５が搬送され、この時、ストッパ１７ｇがローラ間に没してローラよりも下方に位置しているので、裏板搬送路１６を搬送される裏板５がストッパ１７ｇに当たることなく、裏板搬送路１６の終端部まで搬送される。
【００９２】
この段階で第１のプレス手段１２ａは開いており（つまり移動プレス盤４０ａ、４０ｂが対向面間の距離が完成後の該当するウオール用箱体７の左右の側板１間の距離よりも長くなるように開いており）、また、移動プレス盤４０ａは移動プレス盤４０ｂよりも後方側にずれるように後退している。また、天前桟吸着治具４８、天後桟吸着治具４９がそれぞれ上昇している。
【００９３】
前述のように天前桟・天後桟搬送路２２の終端部に搬送された天前桟８、天後桟９をそれぞれ第１の多関節ロボット７０の吸盤部７０ｂにより吸着して第１のプレス手段１２ａの間に運んで図３２に示すように天前桟吸着治具４８、天後桟吸着治具４９に吸着させて保持させる。
【００９４】
また、第１の多関節ロボット７０は上記のように両側板１の嵌合孔２７への接着剤の塗布が完了し且つ第１のプレス手段１２ａが開いていると左右両側板１をそれぞれ１つずつ順に吸着して（内面を吸着して）移動し、それぞれ移動プレス盤４０ａ、４０ｂの各吸着パッド４２に押し付け、吸着パッド４２により側板１を吸着すると第１の多関節ロボット７０による吸着を解除する。この場合の側板１の位置決めは前述と同様である。このようにして、左右の側板１をそれぞれ移動プレス盤４０ａ、４０ｂの所定位置に吸着する。
【００９５】
次に、第１の多関節ロボット７０が地板反転装置３８に反転した状態で保持されている地板４の外面を吸着して移動対向する移動プレス盤４０ａ、４０ｂ間の上部に移動し、上記天前桟吸着治具４８、天後桟吸着治具４９により所定位置に吸着保持されている天前桟８、天後桟９の上方位置に組み立て完成後における天前桟８、天後桟９と地板４との距離と同じ距離を隔てて位置させた状態で保持する。ここで、フロアー用箱体１０の組み立てに当たっては、天前桟吸着治具４８、天後桟吸着治具４９と第１の多関節ロボット７０の吸盤部７０ｂとで天前桟８、天後桟９と地板４とを上下に所定間隔を隔てて保持する保持手段１３を構成している。
【００９６】
上記のように、開いた移動プレス盤４０ａ、４０ｂ間の下部と上部に天前桟８、天後桟９と地板４とを配置した状態で天前桟８、天後桟９と地板４は上記のように組み立て完成後に天前桟８、天後桟９と地板４との距離と同じ距離を隔てて上下に対向していると共に、地板４の後端面が天後桟９の嵌め込み溝２ｄの前端縁と上下に対向している。また、上記のように移動プレス盤４０ａ、４０ｂで左右両側板１が対向するように保持した状態で、両側板１は組み立て完成後の両側板１間の距離よりも長い距離を隔て且つ両側板１の内面の嵌め込み溝２ａ同士が左右に対向している。
【００９７】
次に、シリンダ装置４１ａ、４１ｂにより左右の移動プレス盤４０ａ、４０ｂを互いに近づく方向に移動し、移動プレス盤４０ａ、４０ｂに保持している左右両側板１の内面の上下両端部に設けた接着剤を塗布した嵌合孔２７を天前桟８、天後桟９の両側端面に突設した嵌合突部２８ｃ、２８ｄに嵌め込むのであるが、この場合、嵌合突部２８ｃと嵌合孔２７とで構成する嵌合部１５及び嵌合突部２８ｄと嵌合孔２７とで構成する嵌合部１５の各嵌め込み深さ方向に若干の未嵌め込み部を残すように仮嵌合した状態に仮組みする（図３３参照）ものである。このようにして上記の第１のプレス手段１２ａによるプレスでウオール用箱体７を仮組みするのであるが、この場合、両側板１間の距離は完成後のフロアー用箱体１０の両側板１間の距離より若干短い状態となるように仮組みするものであり、したがって、この段階では両側板１の内面と天前桟８、天後桟９、地板４の各両側端面とは当接しておらず１ｍｍ程度の小間隙が存在するようにしてある（上記未嵌め込み部の長さはこの小間隙と同じ長さと同じである）。
【００９８】
上記のようにフロアー用箱体１０の仮組みが終わると、シリンダ装置４１ａ、４１ｂにより移動プレス盤４０ａ、４０ｂが互いに離れるように移動することで第１のプレス手段１２ａを開き、第１の多関節ロボット７０の吸盤部７０ｂによる地板４の吸着を止め、天前桟吸着治具４８、天後桟吸着治具４９による吸着を止めると共に天前桟吸着治具４８、天後桟吸着治具４９を下降させて仮組み状態のフロアー用箱体１０をプレス内天板搬入コンベア４６に載せ、プレス内天板搬入コンベア４６を駆動して仮組み状態のフロアー用箱体１０を第２のプレス手段１２ｂ内のベルトコンベア５８ａ、５８ｂに送り込む。
【００９９】
この場合、第２のプレス手段１２は開いていて第１のプレス手段１２ａにより仮組みしたウオール用箱体７を第２のプレス盤４０ｂ内のベルトコンベア５８ａ、５８ｂに移送した際に移送されるフロアー用箱体１０が奥行き位置決め治具６２に当たらないようになっている。また、両側の仮組み箱位置決め部材６１ｂが両移動プレス盤５４ａ、５４ｂ間内に突出している。
【０１００】
ベルトコンベア５８ａ、５８ｂに移送された仮組みされたフロアー用箱体１０は仮組み箱位置決め部材６１ｂに当たるので、この段階でベルトコンベア５８ａ、５８ｂが停止し、その後、仮組み箱位置決め部材６１ｂが移動して仮組み状態のフロアー用箱体１０に当接して左右方向の位置決めをし、また、移動プレス盤５４ａ、５４ｂを互いに近づく方向に移動して仮組み状態のフロアー用箱体１０の両側板１に当接して、仮組み状態のフロアー用箱体１０の巾方向（左右方向）の位置決めを行い、また、奥行き位置決め治具６２が前方に移動して仮組み状態のウオール用箱体７に当接して前後方向の位置決めをして保持する（図３４参照）。この状態で、略逆ハ字状をした裏板挿入ガイド６３の下開口が両側板１の嵌め込み溝２ａの長手方向の端部と上下に対向している。
【０１０１】
次に、第２の多関節ロボット７１の吸盤部７１ｂにより裏板搬送路１６の終端部に搬送されている裏板５を吸着して図３５、図３６のように裏板挿入ガイド６３の上開口に移動して挿入し、引き続き第２の多関節ロボット７１により裏板挿入ガイド６３の下開口を経て地板４（この状態では地板４は上に位置している）の後端面に沿って裏板５を裏板挿入ガイド６３から両側板１の嵌め込み溝２ａに上から挿入し、裏板５の挿入方向の先端を天後桟９の嵌め込み溝２ｄに嵌め込む。したがって、フロアー用箱体１０の組立の場合、第２の多関節ロボット７１が裏板移動手段１４ｂを構成している。この場合、あらかじめ固着している裏桟６が上となるようにして挿入する。
【０１０２】
その後、移動プレス盤５４ａ、５４ｂを互いに近づく方向に移動し、仮組み状態のウオール用箱体７の両側板１を押圧プレスして両側板１の内面を天前桟８、天後桟９、地板４それぞれの両側端面に圧接すると共に仮組み段階で嵌め込み方向に未嵌合部を残していた嵌合部１５の未嵌合部を嵌め込み方向に完全に嵌合する。
【０１０３】
次に、ベルトコンベア５８ａ、５８ｂを下降させ、多関節ロボット７１の固着具打ち込み装置７１ｃにより図３７のように側板１と天前桟８、側板１と天後桟９、側板１と裏板５をそれぞれ接合するようにタッカー釘のような固着具７３を打ち込み本組み立て状態で各部材同士を固着する。
【０１０４】
このようにして本組み立てが完了すると、固着具７３の打ち込みの際に下降していたベルトコンベア５８ａ、５８ｂを上昇させて組み立てが完成したフロアー用箱体１０の下面に当て、移動プレス盤５４ａ、５４ｂが互いに離れる方向に移動して第２のプレス手段１２ｂを開き、仮組み箱位置決め部材６１ｂを後退させ、ベルトコンベア５８ａ、５８ｂを駆動して組み立て完了したフロアー用箱体１０を箱体搬出路５３に送って搬出するものである。
【０１０５】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、共通の組み立てラインによりウオール用箱体とフロアー用箱体とを選択的に組み立てることができるので、共通の組み立てラインによりウオール用箱体とフロアー用箱体とを選択的に組み立てることができて、組み立てに要するスペースが従来に比べて狭いスペースでよく、また、組み立て効率も良くなって生産性が向上するものである。
