Description

【０００１】
【発明の属する技術分野】
この発明はパチンコ機のような遊技機を製造する際に、検査で不良と認定された遊技基板又は遊技基板に意匠図の描かれた遊技盤を搬送ラインより自動的に排出する装置に関する。
【０００２】
【従来の技術】
パチンコ機メーカーでは、ベニヤ板のような遊技基板の片側表面に意匠図の描かれたセルシートを一体に結合するセル貼付工程、事後工程での作業の位置決めとなる基準孔やガイドレールの取付用孔を切削加工する多軸穴空け工程、遊技釘や遊技機能部品取付用の下穴を押し空けるゲージプレス工程、遊技機能部品取付用の開口を切削加工するルータ工程、遊技釘を打ち込む釘打ち工程、ガイドレールや遊技機能部品を取り付ける組み立て工程、遊技機能部品が正常に動作するか検査する検査工程等を順に経て遊技盤（ゲージ盤）を製造している。
【０００３】
【発明が解決しようとする課題】
遊技基板又は遊技盤の外形寸法、厚さ、直角度、反り等の物理的諸元が所定範囲に入っていないと、セル貼付工程でセルシートの位置決め不良やセルシート貼付不良を生じ、ルータ工程で座繰りの深さ不良を生じ、釘打ち工程で遊技釘が打ち込めないような打ち込み不良を生じたり、又、完成した遊技盤が当該遊技盤をパチンコ店の島に取り付けるための機枠に入りにくいという不都合がある。このようなことから、木工メーカーより略方形に切断されたベニヤ板のような遊技基板が例えば４枚平面的に格子状に並べられた組をパレット上に７０段〜８０段程度積み重ねられて納入された遊技基板ブロックを１ロットとし、作業者が１ロット毎に数枚の遊技基板を抜き取って所定の検査項目に従って測定する抜き取り検査を行っており、生産効率の低下が否めなかった。
【０００４】
そこで、この発明は遊技基板又は遊技盤を搬送ライン上で検査した際に、不良と認定された遊技基板又は遊技盤を搬送ラインより自動的に排出して、生産効率を高めることができる遊技機製造用不良遊技基板又は不良遊技盤の排出装置を提供しようとするものである。
【０００５】
【課題を解決するための手段】
本発明に係る遊技機製造用不良遊技基板又は不良遊技盤の排出装置は、遊技基板又は遊技基板に意匠図の描かれた遊技盤を搬送する搬送ラインを搬送ラインの搬送方向の中間部で上流側搬送ラインと下流側搬送ラインとに分割し、分割された上流側搬送ラインと下流側搬送ラインとを互いに上記搬送方向に離隔配置して、上流側搬送ラインと下流側搬送ラインとの相互間に遊技基板又は遊技盤を搬送姿勢のまま取り込むための不良排出空間を形成し、上流側搬送ラインには当該上流側搬送ラインで搬送される遊技基板又は遊技盤の不良を検出するための検査装置を設け、不良排出空間には、上流側搬送ラインから不良排出空間に向けて遊技基板又は遊技盤を上記搬送方向と同じ方向に搬送する搬送機構と、この搬送機構の下方に位置して当該搬送機構より落下する不良と検出された遊技基板又は遊技盤を受け取って不良排出空間より排出する排出機構とを設け、上記不良排出空間に設けられた搬送機構は、上記搬送方向と交差する方向に相対峙してアクチュエーターで前進後退する一対の可動板と、一対の可動板の内側に設けられて上記搬送方向と同じ方向に上流側搬送ラインより受け取った遊技基板又は遊技盤を下流側搬送ラインにアクチュエーターで遊技基板又は遊技盤を搬送する搬送路を形成するように上記搬送方向と交差する方向に相対峙する一対の搬送部とを備え、一対の可動板がアクチュエーターにより不良排出空間の上記搬送方向と交差する外側から不良排出空間の方向に向けて互いに近づく方向に前進して停止しており、一対の搬送部がアクチュエーターにより遊技基板又は遊技盤を上流側搬送ラインから不良排出空間を経由して下流側搬送ラインに搬送する形態において、検査装置が上流側搬送ラインで搬送される遊技基板又は遊技盤の不良を検出し、検査装置で不良として検出された遊技基板又は遊技盤が上流側搬送ラインから不良排出空間に到達した場合は、一対の可動板がアクチュエーターにより不良排出空間から上記搬送方向と交差する外側に向けて後退することによって、一対の搬送部の相対峙する間隔が上流側搬送ラインより受け取った不良と検出された遊技基板又は遊技盤を搬送路より搬送姿勢のまま排出機構に向けて落下させるための空間として形成されることを特徴としている。本発明に係る遊技機製造用不良遊技基板又は不良遊技盤の排出装置によれば、上流側搬送ラインと不良排出空間に設けられた搬送機構および下流側搬送ラインが遊技基板又は遊技盤を上流側搬送ラインから下流側搬送ラインに向けて搬送する過程において、検査装置が上流側搬送ラインから不良排出空間に設けられた搬送機構に送られる遊技基板又は遊技盤を不良と検出し、この不良と検出された遊技基板又は遊技盤が搬送ラインより搬送機構における一対の搬送部を経由して不良排出空間に到達すると、搬送機構における一対の可動板が後退して当該不良と認定された遊技基板又は遊技盤を搬送姿勢のまま一対の搬送部から下方に落下し、この搬送姿勢のまま落下する遊技基板又は遊技盤を排出機構が受け取って不良排出空間より排出することにより、不良排出空間より下流側での無駄な製品作りを不良と認定された遊技基板又は遊技盤に行うことなく、コストダウンを図り、生産効率を向上することができる。一対の搬送部よりも上方に突出する一対の可動板の内側面が一対の搬送部で搬送される遊技基板又は遊技盤を搬送方向に誘導するガイド部として形成されれば、搬送機構における一対の搬送部が遊技基板又は遊技盤を上流側搬送ラインから下流側搬送ラインに的確に誘導することができる。不良排出空間の下流側にはアクチュエーターで可動板と同じ方向に前進後退する基板ストッパーが設けられ、検査装置で不良と検出されていない遊技基板又は遊技盤が上流側搬送ラインから不良排出空間に送られる場合は、基板ストッパーがアクチュエーターにより搬送機構における搬送部の搬送路から後退して停止しており、検査装置で不良と検出された遊技基板又は遊技盤が上流側搬送ラインから不良排出空間に送られる場合は、基板ストッパーがアクチュエーターにより搬送機構における搬送部の搬送路に突出して上流側搬送ラインから不良排出空間に送られた不良と検出された遊技基板又は遊技盤を不良排出空間に停止すれば、排出しようとする不良と検出された遊技基板又は遊技盤の位置を正確に決めて、当該遊技基板又は遊技盤を的確に排出することができる。不良排出空間には不良排出空間に設けられた搬送機構から排出機構に不良と検出された遊技基板又は遊技盤を搬送姿勢のまま受け渡す受渡機構を設け、受渡機構は、上記搬送方向と交差する方向に相対峙してアクチュエーターで可動板と同じ方向に前進後退する一対の受体と、上記搬送方向と交差する方向に相対峙する一対の突当棒とを備え、検査装置で不良と検出されていない遊技基板又は遊技盤が上流側搬送ラインから不良排出空間に送られる場合は、一対の受体がアクチュエータにより不良排出空間から不良排出空間の上記搬送方向と交差する外側に向けて後退して停止しており、検査装置で不良と検出された遊技基板又は遊技盤が上流側搬送ラインから不良排出空間に到達した場合は、一対の受体がアクチュエーターにより不良排出空間の上記搬送方向と交差する外側から不良排出空間の方向に向けて互いに近づく方向に前進して停止することによって搬送機構における一対の搬送部の上に位置する遊技基板又は遊技盤の下に潜り込んで搬送機構における一対の可動板の後退に伴う一対の搬送部の間より落下する遊技基板又は遊技盤を搭載させた後に、一対の受体がアクチュエーターにより不良排出空間から不良排出空間の上記搬送方向と交差する外側に向けて後退することによって、一対の受体の相対峙する間隔が上流側搬送ラインより受け取った不良と検出された遊技基板又は遊技盤を一対の受体より搬送姿勢のまま排出機構に向けて落下させるための空間として形成され、この一対の受体の相対峙する間隔が上流側搬送ラインより受け取った不良と検出された遊技基板又は遊技盤を一対の受体より搬送姿勢のまま排出機構に向けて落下させるための空間として形成される過程において、一対の突当棒が一対の可動板の後退により一対の可動板よりも不良排出空間の方向である内側に突出することによって遊技基板又は遊技盤を後退する一対の受体と共連れしないように押して一対の受体から落下させれば、一対の受体から落下する遊技基板又は遊技盤が落下時にそれ以外の部分に鋭角状に衝突して損傷を受けるような不都合を解消することができる。排出機構は、搬送機構から落下した遊技基板又は遊技盤を多数枚積み重ねてブロックに形成するリフターと、リフターより搬送されたブロックを受け取る積替機構とを備えれば、不良と検出された遊技基板又は遊技盤を多数枚一塊として、搬送ラインより所定の不良材料貯留所に運搬することができる。
【０００６】
【発明の実施の形態】
図１〜８は一実施形態を示している。図１において、遊技基板１を搭載して搬送方向Ｘに向けて搬送する搬送ライン２は、遊技基板１の搬送方向Ｘと直交する前後方向に所定間隔を以て相対峙された一対のコンベアフレーム２ａに複数のローラー２ｂを搬送方向Ｘに並列配置したローラーコンベアに形成されている。搬送ライン２には遊技基板１が１枚だけ搬送姿勢のまま取り込める平面積を有する不良排出空間３が形成されている。実際には、搬送ライン２を搬送方向Ｘの中間部で分割し、分割された上・下流側のライン構成要素を互いに搬送方向Ｘに離隔配置して、ライン構成要素の相互間に不良排出空間３を形成するが、図を簡明にすることから、図１では上流側のライン構成要素のみを、搬送ライン２として図示し、下流側のライン構成要素を省略してある。不良排出空間３には装置本体４を搬送ライン２から搬出される遊技基板１と干渉しないように配置してある。
【０００７】
装置本体４には一対の搬送機構５を前後方向に所定間隔を以て相対峙させて設けてある。各搬送機構５は、装置本体４に取り付けられたエアーシリンダーのようなアクチュエーター５ａにより搬送方向Ｘと交差する前後方向に前進後退する可動板５ｂの内側に複数のローラー５ｃを搬送方向Ｘに一列状に配置して回転可能に取り付け、各ローラー５ｃを可動板５ｂに支持している図外のシャフトが可動板５ｂより外側に突出する後端に結合されたドリブンプーリー５ｄと装置本体４に図外のステーを介して取り付けられたモーター５ｅの出力端に結合されたドライブプーリー５ｆとに無端状のベルト５ｇを掛け渡してある。
【０００８】
この実施形態の搬送機構５では、不良排出空間３の上流側に設けられた図外の検査装置が遊技基板１の外形寸法、厚さ、直角度、反り等の不良を検出しない際には、一対の可動板５ｂが互いに近づく前進限度位置に停止していて、モーター５ｅにより複数のローラー５ｃが一方向に回転駆動することで、各ローラー５ｃが搬送ライン２より不良排出空間３に搬出された遊技基板１を搬送方向Ｘに搬送して、図外の下流側の搬送ラインに移送する。各ローラー５ｃよりも上方に突出する可動板５ｂの内側面はローラー５ｃで搬送される遊技基板１を搬送方向Ｘに的確に誘導するガイド部として形成されている。
【０００９】
前記図外の検査装置が遊技基板１の不良を検出し、不良として検出された遊技基板１が不良排出空間３に到達する時期に、一対の可動板５ｂが互いに離れる後退限度位置に停止することで、前後方向に相対峙するローラー５ｃの間隔が搬送ライン２より不良排出空間３に搬出された遊技基板１の前後方向の横幅より大きい寸法に設定されて、当該前後方向のローラー５ｃの間より遊技基板１を落下する。
【００１０】
不良排出空間３の搬送方向Ｘの下流側には一対の基板ストッパー６を前後方向に所定間隔を以て相対峙させて配置してある。基板ストッパー６は装置本体４に取り付けられたエアーシリンダーのようなアクチュエーター６ａにより搬送機構５のローラー５ｃと同方向に前進後退可能に設けられている。前記図外の検査装置が遊技基板１の不良未検出中は、基板ストッパー６は搬送機構５におけるローラー５ｃの上側搬送部で形成される遊技基板１の搬送路上より退避するように後退限度位置に停止していて、搬送機構５が遊技基板１を搬送方向Ｘに搬送する機能を継続させる。前記図外の検査装置が遊技基板１の不良を検出し、不良として検出された遊技基板１が不良排出空間３に到達する時期に、基板ストッパー６は後退限度位置より前進して搬送機構５で搬送される遊技基板１の搬送路上に突出するように前進限度位置に停止することで、当該遊技基板１の搬送を強制的に停止する。
【００１１】
不良排出空間３における搬送方向Ｘの上・下流側及び前後方向には受渡機構７を設けてある。即ち、受渡機構７は不良排出空間３の４隅のそれぞれに対応して設けられている。受渡機構７は可動板５ｂの後退で搬送機構５の間より落下する遊技基板１の落下姿勢を搬送ライン２及び搬送機構５での搬送姿勢と同様な水平面状に矯正するものであって、装置本体４に取り付けられたエアーシリンダーのようなアクチュエーター７ａにより搬送機構５のローラー５ｃと同方向に前進後退可能に設けられた受体７ｂと、各受体７ｂの近傍でアクチェーター７ａのケーシングのような静止部に取り付けられた突当棒７ｃとを備えている。
【００１２】
この実施形態の受渡機構７では、前記図外の検査装置が遊技基板１の不良未検出中は、受体７ｂが搬送機構５のローラー５ｃとこれに隣接するローラー５ｃとの間で可動体５ｂに形成された切欠部５ｈより後退限度位置に停止している。前記図外の検査装置が遊技基板１の不良を検出し、不良として検出された遊技基板１が不良排出空間３に到達した際に、受体７ｂが搬送機構５の切欠部５ｈを経由して前進限度位置に停止することで、受体７ｂの水平片が搬送機構５のローラー上に位置する遊技基板１の下に潜り込み、受体７ｂの垂直片が遊技基板１の前後側面に近接対向する。搬送機構５の可動板５ｂが後退し、ローラー５ｃの間より落下する遊技基板１が受体７ｂの水平片の上に搭載された後に、受体７ｂが後退限度位置に停止することで、前後方向に相対峙する受体７ｂの水平片の間隔が遊技基板１の横幅より大きい寸法に設定されて、当該前後方向に相対峙する受体７ｂの間より遊技基板１が落下する。
【００１３】
各突当棒７ｃの先端は、搬送機構５の前進限度位置に停止した可動板５ｂの切欠部５ｈにおいて、遊技基板１の前後側面に近接対向するように、可動板５ｂの内側面と略面一に位置していて、搬送機構５で搬送される遊技基板１と干渉しないようになっている。又、各突当棒７ｃの先端は、搬送機構５の後退限度位置への停止で可動板５ｂの切欠部５ｈより内側に突出して、受体７ｂが後退限度位置に停止する際に、遊技基板１が受体７ｂに共連れされるのを防止して、遊技基板１を傾くことなく水平面状に正確に落下させる。
【００１４】
不良排出空間３には、排出機構８を搬送機構５の下方に位置して設けてある。排出機構８は搬送機構５及び受渡機構７の間より落下した遊技基板１を装置外に排出するものであって、この実施形態では、落下した遊技基板１を多数枚積み重ねてブロックに形成するリフター９と、リフター９よりブロックを運搬台車１１に積み替える積替機構１０とを備えている。リフター９は、不良検出毎に、基板ストッパー６の前進・後退、搬送機構５の後退・前進、受渡機構７の前進・後退を行うことにより、落下した遊技基板１を受け取る毎に下から上へ順に積み重ねると共に、遊技基板１が１枚積み重ねられる毎に、その１枚分の厚さだけ下降し、次に落下する遊技基板１をなるべく少ない所定距離だけ落下してリフター９上の最上段の遊技基板１の上に積み重ねるようになっている。
【００１５】
又、リフター９は昇降及び搬送可能なリフトベース９ａを有している。リフトベース９ａは、不良排出空間３の後方に位置する装置本体４の背部に取り付けられたモーターのようなアクチュエーター９ｂによりボルト・ナット機構９ｃを介して昇降すると共に、装置本体４の背部に立設された左右のガイドレールとこれらに摺接係合してリフトベース９ａに固定されたスライダーとからなるクロスローラーのようなガイド機構９ｄで横振れ防止されている。リフトベース９ａは遊技基板１のブロックを搬送方向Ｘと交差する装置本体４の前方への排出方向Ｙに搬送する複数のローラー９ｅを備えている。これらのローラー９ｅの中のいくつかはモーターのような電磁作用で排出方向Ｙに回転駆動するモーターローラーに形成されており、残りのローラー９ｅは自由回転するフリーローラーになっている。複数のローラー９ｅの軸方向両端側で、リフトベース９ａには左右のガイドプレート９ｆを備えている。各ガイドプレート９ｆはローラー９ｅで搬送される遊技基板１のブロックを排出方向Ｙに的確に誘導する。
【００１６】
積替機構１０は、装置本体４の下部に取り付けられたシーソー１０ａを備えている。シーソー１０ａは装置本体４に取り付けられたエアーシリンダーのようなアクチュエーター１０ｂで軸部材１０ｃを中心として上下方向に揺動する。シーソー１０ａの装置本体４の内部から前方外側に突出する先端部にはドライブローラー１０ｄとフリーローラー１０ｅとストッパー１０ｆとセンサー１０ｇとを備えている。
【００１７】
この実施形態のリフター９に所定枚数の遊技基板１を積み重ねたブロックが形成され、リフトベース９ａが下降限度位置に到達した際、シーソー１０ａの先端部が実線示の上昇限度位置に上昇して、ドライブローラー１０ｄがリフター９のローラー９ｅと同一速度で同方向に回転駆動することで、遊技基板１のブロックがリフター９より装置本体４に取り付けられたリリーフローラー１２を経由してドライブローラー１０ｄ及びフリーローラー１０ｅに搬送する。このブロックがストッパー１０ｆに当接する位置又は直前で、前記ドライブローラーの回転駆動が停止すると共に、図外のブロック排出完了通知表示手段により遊技基板１のブロックが装置外に搬出されたことを作業者に知らせる。
【００１８】
この通知により、作業者が上昇限度位置におけるシーソー１０ａの先端部よりも下方に形成された空間に運搬台車１１を挿入し、この運搬台車１１をセンサー１０ｇが運搬台車１１を検出することで、図外のストライカーが運搬台車１１を装置本体４に対して位置固定した後に、シーソー１０ａの先端部が上昇限度位置から下降限度位置に下降する。この下降途中で、シーソー１０ａが先端部に搭載されていた遊技基板１のブロックを運搬台車１１の左右より立ち上げられた搭載部１１ａに受け渡す。
【００１９】
図１中の符号１３はリフトベース９ａよりも後方で装置本体４に搬送機構５側から下に向けて縦方向に組付けられる基板ガイドで、この基板ガイド１３はリフトベース９ａの下降時に遊技基板１のブロックの荷崩れを防止する。又、図１において、基板ガイド１３と対応する装置本体４の前側に高さの低い図外の基板ガイドを設け、この図外の基板ガイドと前記基板ガイド１３とがそれらの間に受渡機構７より落下する遊技基板１を水平状に落下させるように誘導して、当該遊技基板１をリフトベース９ａの上に搭載する。
【００２０】
この実施形態の動作について図２〜７を参照しながら説明する。搬送機構５の可動板５ｂが前進限度位置に停止していて、遊技基板１が搬送ライン２から搬送機構５を経由して搬送方向Ｘに向けて搬送されている状態において、図外の不良検出装置が不良検出信号を出力し、その不良検出信号を出力する元になった不良と認定された遊技基板１が可動板５ｂに沿ってローラー５ｃに載って不良排出空間３に到達すると、図２に示すように、遊技基板１が搬送路上に突出した基板ストッパー６に当接し、遊技基板１の搬送が規制される。
【００２１】
次に、図３に示すように、受渡機構７の受板７ｂが前進してローラー５ｃの上の遊技基板１の前後方向より下に潜り込む。
【００２２】
その後、図４に示すように、可動板５ｂが後退し、ローラー５ｃが遊技基板１より逃げて、遊技基板１が受体７ｂで支持される。
【００２３】
引き続き、図５に示すように、受体７ｂが後退する。この後退時において、突当棒７ｃが遊技基板１の前後方向の側面に対応しているので、遊技基板１が受体７ｂと共連れしようとしても、遊技基板１が突当棒７ｃに当接して当該遊技基板１の共連れを阻止し、遊技基板１が図５のｂ図に示す実線示から仮想線示のように水平面状を維持して受板７ｂより落下し、この遊技基板１が受取位置に停止したリフトベース９ａのローラー９ｅに搭載される。このリフトベース９ａの受取位置は、リフトベース９ａに既に遊技基板１が搭載されている際には、その時点での最上段の遊技基板１が受渡機構７の受板７ｂに搭載された遊技基板１に干渉しない範囲で接近した一定位置となるように、不良と認定された遊技基板１を排出する毎に、遊技基板１の１枚分の厚さを加味したモーター９ｂの回転駆動量によって制御される。又、図３に示す基板ストッパー６は遊技基板１を止めた後に、次の正常な遊技基板１が不良排出空間３に来るまでに後退すれば、当該正常な遊技基板１の通行を邪魔しないが、例えば、不良と認定された遊技基板１が受体７ｂからリフトベース９ａに落下した後に後退させれば、当該不良の遊技基板１が受体７ｂよりリフトベース９ａに落下する際に、基板ストッパー６が位置決めとして働き、遊技基板１をリフトベース９ａの上に正確に段積みすることができる。
【００２４】
そして、図６に示すように、遊技基板１を受け取ったリフトベース９ａが退避位置に下降する。後退位置において、リフトベース９ａに搭載された不良として検出された実線で示す遊技基板１が、搬送機構５や受渡機構７と干渉しないようになっている。このリフトベース９ａが下降する途中で、遊技基板１は基板ガイド１３で荷崩れしないように案内される。このリフトベース９ａの退避位置は、既に遊技基板１が搭載されている際には、その時点での最上段の遊技基板１が搬送機構５や受渡機構７に干渉しない範囲でなるべく上位となる一定位置となるように、遊技基板１の不良排出動作毎に、遊技基板１の１枚分の厚さを加味したモーター９ｂの回転駆動量によって制御される。
【００２５】
この後、搬送機構５の可動板５ｂが後退限度位置から前進限度位置に停止し、搬送ライン２からの遊技基板１を搬送方向Ｘに向けて搬送する通常状態に復帰する。この通常状態は、図５のａ図において、基板ストッパー６が後退限度位置に停止して遊技基板１の搬送路上より退避した態様である。
【００２６】
前記図２〜６に示した工程を不良検出毎に繰り返すことで、遊技基板１がリフトベース９ａの上に所定枚数積み重ねられ、その都度、遊技基板１の１枚分の厚さだけ下降したリフトベース９ａにおけるローラー９ｅの上側搬送部が、図７〜８に示すように、上昇限度位置の排出機構１０のドライブローラー１０ｄの上側搬送部と略同一高さとなる下降限度位置に到達した場合に、作業者が運搬台車１１をシーソー１０ａの先端部よりも下方の空間に挿入する。
【００２７】
そして、図外のストライカーが運搬台車１１を装置本体４に対して位置固定した後に、ローラー９ｅとドライブローラー１０ｄとが回転駆動して遊技基板１が所定枚数積み重ねられたブロックを排出方向Ｙに搬送し、そのブロックが図７の実線示から仮想線示のようにリフトベース９ａよりシーソー１０ａの先端部に移送されたら、シーソー１０ａが上昇限度位置から下降限度位置へと下降し、その下降途中で、前記ブロックがシーソー１０ａの先端部より運搬台車１１の搭載部１１ａに受け渡される。この状態において、作業者が運搬台車１１をシーソー１０ａの前方に引き出して、所定の不良材料貯留所に格納する。
【００２８】
要するに、この実施形態の構成によれば、不良と認定された遊技基板１が搬送ライン２から搬送機構５に移送されて不良排出空間３で基板ストッパー６に受け止められて停止すると、受渡機構７の受体７ｂが遊技基板１の下に潜り込む。そして、搬送機構５の可動板５ｂが後退すると、遊技基板１が搬送機構５のローラー５ｃの前後方向の間より落下して受体７ｂに受け止められる。その後、受体７ｂが後退して遊技基板１が受体７ｂの前後方向の間より落下する際、受渡機構７の突当棒７ｃが遊技基板１の受体７ｂとの共連れを防止して遊技基板１を水平状に落下させることができる。この落下する遊技基板１はその下で受体７ｂに最も接近した受取位置に停止したリフトベース９ａに搭載され、遊技基板１が落下時にそれ以外の部分に鋭角状に衝突して損傷を受ける不都合を解消することができる。この搭載と並行し、基板ストッパー６が後退限度位置に停止すると共に、搬送機構５の可動板５ｂが前進限度位置に復帰し、不良と認定された１枚の遊技基板１を遊技機製造用の搬送ライン２から排出する１回の動作が終了する。この排出動作が、搬送ライン２で搬送される遊技基板１が不良と認定される毎に、繰り返されることで、当該不良と認定された遊技基板１がリフトベース９ａに所定枚数積み重ねられてブロックを形成すると、リフター９のローラー９ｅと積替機構１０のドライブローラー１０ｄとが同方向に同一速度で回転駆動してブロックを装置外に排出することができる。この排出されたブロックを積替機構１０より運搬台車１１に積み替えて不良材料貯留所に運搬して格納することができる。
【００２９】
前記実施形態では意匠図の描かれた遊技基板１を図示して説明したが、例えば、遊技基板１の一表面に意匠図の描かれたセルシートが結合された遊技盤を遊技基板１に代えても同様に適用できる。この場合、前記実施形態の遊技基板１を遊技盤と読み替えることで、実施できることは明らかであろう。尚、遊技盤に意匠図が描かれているとは、遊技基板１の一表面に意匠図を直接印刷したり、意匠図が印刷されたセルシートを遊技基板１の一表面に結合することが含まれる。
【００３０】
又、排出機構８は搬送機構５より落下した遊技基板１又は遊技盤を斜め下方に滑落させるシューターのように形成してもよい。
【００３１】
又、受渡機構７、基板ストッパー６のいずれか一方又は両方を省略した構造でも適用できることは勿論である。
【００３２】
尚、前記実施形態において、不良排出空間３よりも下流側の加工領域に遊技基板１が滞留した際に、基板ストッパー６を搬送機構５のローラー５ｃによる遊技基板１の搬送路上に突出させて、正常な遊技基板１をローラー５ｃの上で止め置き、当該下流側の加工領域での遊技基板１の滞留が解消した際に、基板ストッパー６を上記搬送路より後退させて、上記止め置かれた正常な遊技基板１を下流側の加工領域に流すというように、下流側の加工領域での遊技基板１の滞留状態に関連して基板ストッパー６を動作すれば、下流側の加工領域での作業の健全化も図ることができる。

DETAILED DESCRIPTION OF THE INVENTION
1-8 show one embodiment. In FIG. 1, a transport line 2 on which a game board 1 is mounted and transported in the transport direction X is formed between a pair of conveyor frames 2 a that are opposed to each other at a predetermined interval in the front-rear direction perpendicular to the transport direction X of the game board 1. It is formed on a roller conveyor in which a plurality of rollers 2b are arranged in parallel in the transport direction X. The transfer line 2 is formed with a defective discharge space 3 having a plane area in which only one game board 1 can be taken in the transfer posture. Actually, the conveyance line 2 is divided at an intermediate portion in the conveyance direction X, and the divided upstream and downstream line components are separated from each other in the conveyance direction X so that a defective discharge space is formed between the line components. In order to simplify the drawing, only the upstream line components are shown as the transport line 2 in FIG. 1, and the downstream line components are omitted. The apparatus main body 4 is arranged in the defective discharge space 3 so as not to interfere with the game board 1 carried out from the transfer line 2.
[0007]
The apparatus main body 4 is provided with a pair of transport mechanisms 5 that are opposed to each other at a predetermined interval in the front-rear direction. Each transport mechanism 5 has a plurality of rollers 5c arranged in a row in the transport direction X inside a movable plate 5b that moves forward and backward in the front-rear direction intersecting the transport direction X by an actuator 5a such as an air cylinder attached to the apparatus body 4. It is attached to the main body 4 and a driven pulley 5d coupled to the rear end of which a shaft (not shown) supporting each roller 5c on the movable plate 5b protrudes outward from the movable plate 5b. An endless belt 5g is stretched around a drive pulley 5f coupled to the output end of a motor 5e attached via the stay.
[0008]
In the transport mechanism 5 of this embodiment, when an inspection device (not shown) provided on the upstream side of the defective discharge space 3 does not detect defects such as the external dimensions, thickness, squareness, and warp of the game board 1, The pair of movable plates 5b are stopped at the advance limit position where they are close to each other, and the plurality of rollers 5c are driven to rotate in one direction by the motor 5e, whereby each roller 5c is carried out from the transport line 2 to the defective discharge space 3. The game board 1 is transported in the transport direction X and transferred to a downstream transport line that is not shown. From each roller 5c Also The inner surface of the movable plate 5b protruding upward is formed as a guide portion that accurately guides the game board 1 transported by the roller 5c in the transport direction X.
[0009]
The inspection device (not shown) detects a defect of the game board 1 and stops at a retreat limit position where the pair of movable plates 5b are separated from each other when the game board 1 detected as defective reaches the defect discharge space 3. Thus, the distance between the rollers 5c facing each other in the front-rear direction is set to be larger than the width in the front-rear direction of the game board 1 carried out from the transport line 2 to the defective discharge space 3, and between the rollers 5c in the front-rear direction. The game board 1 is dropped.
[0010]
A pair of substrate stoppers 6 are disposed on the downstream side of the defective discharge space 3 in the transport direction X so as to face each other at a predetermined interval in the front-rear direction. The substrate stopper 6 is provided so as to be able to advance and retreat in the same direction as the roller 5 c of the transport mechanism 5 by an actuator 6 a such as an air cylinder attached to the apparatus main body 4. While the inspection device (not shown) is not detecting a defect of the game board 1, the board stopper 6 is at the retreat limit position so as to retreat from the conveyance path of the game board 1 formed by the upper conveyance section of the roller 5c in the conveyance mechanism 5. The function that the transport mechanism 5 transports the game board 1 in the transport direction X is continued. When the inspection device (not shown) detects a defect of the game board 1 and the game board 1 detected as defective reaches the defect discharge space 3, the board stopper 6 moves forward from the retreat limit position and is moved by the transport mechanism 5. By stopping at the forward limit position so as to protrude onto the transfer path of the game board 1 being transferred, the transfer of the game board 1 is forcibly stopped.
[0011]
A delivery mechanism 7 is provided on the upstream and downstream sides of the conveyance direction X in the defective discharge space 3 and in the front-rear direction. That is, the delivery mechanism 7 is provided corresponding to each of the four corners of the defective discharge space 3. The delivery mechanism 7 corrects the falling posture of the game board 1 that falls from between the transport mechanisms 5 due to the retreat of the movable plate 5b to a horizontal plane similar to the transport posture in the transport line 2 and the transport mechanism 5, A receiver 7b provided to be able to advance and retreat in the same direction as the roller 5c of the transport mechanism 5 by an actuator 7a such as an air cylinder attached to the main body 4, and a casing of the actuator 7a in the vicinity of each receiver 7b. And an abutting bar 7c attached to the stationary part.
[0012]
In the delivery mechanism 7 of this embodiment, while the inspection device (not shown) is not detecting a defect of the game board 1, the receiver 7b is movable between the roller 5c of the transport mechanism 5 and the roller 5c adjacent thereto. It stops in the retreat limit position from the notch part 5h formed in this. When the inspection device (not shown) detects a defect of the game board 1 and the game board 1 detected as defective reaches the defect discharge space 3, the receiver 7b passes through the notch 5h of the transport mechanism 5. By stopping at the forward limit position, the horizontal piece of the receiver 7b sinks under the game board 1 located on the roller of the transport mechanism 5, and the vertical piece of the receiver 7b is close to and faces the front and rear sides of the game board 1. . After the movable plate 5b of the transport mechanism 5 moves backward and the game board 1 that falls from between the rollers 5c is mounted on the horizontal piece of the receiver 7b, the receiver 7b stops at the retract limit position, The distance between the horizontal pieces of the receiving body 7b facing in the direction is set to be larger than the lateral width of the gaming board 1, and the gaming board 1 falls between the receiving bodies 7b facing in the front-rear direction.
[0013]
The tip of each abutting bar 7c is substantially flush with the inner surface of the movable plate 5b so as to face and oppose the front and rear side surfaces of the game board 1 at the notch 5h of the movable plate 5b stopped at the forward limit position of the transport mechanism 5. It is located in one, and it does not interfere with the game board | substrate 1 conveyed by the conveyance mechanism 5. FIG. Further, the tip of each abutting bar 7c protrudes inward from the cutout portion 5h of the movable plate 5b when the transport mechanism 5 stops at the retreat limit position, and when the receiving body 7b stops at the retreat limit position, the game board 1 is prevented from being accompanied by the receiver 7b, and the game board 1 is accurately dropped in a horizontal plane without being inclined.
[0014]
In the defective discharge space 3, a discharge mechanism 8 is provided below the transport mechanism 5. The discharge mechanism 8 discharges the game board 1 dropped from between the transport mechanism 5 and the delivery mechanism 7 to the outside of the apparatus. In this embodiment, a lifter that stacks a number of dropped game boards 1 to form a block. 9 and transshipment machine to transfer blocks from lifter 9 to transport cart 11 Structure 10. The lifter 9 advances and retreats the substrate stopper 6, retreats and advances the transport mechanism 5, and advances and retreats the delivery mechanism 7 every time a defect is detected, so that the lifter 9 moves from the bottom to the top each time it receives the dropped game board 1. The game board 1 is stacked one by one, and each time one game board 1 is stacked, the game board 1 descends by the thickness of one game board, and then drops the game board 1 that is dropped by a predetermined distance as little as possible. It is designed to be stacked on the substrate 1.
[0015]
The lifter 9 has a lift base 9a that can be moved up and down. The lift base 9a is moved up and down via a bolt / nut mechanism 9c by an actuator 9b such as a motor attached to the back of the apparatus main body 4 located behind the defective discharge space 3, and is erected on the back of the apparatus main body 4. Lateral shaking is prevented by a guide mechanism 9d such as a cross roller which is composed of the left and right guide rails and a slider which is slidably engaged with and fixed to the lift base 9a. The lift base 9 a is provided with a plurality of rollers 9 e that convey the block of the game board 1 in the discharge direction Y forward of the apparatus main body 4 that intersects the conveyance direction X. Some of these rollers 9e are formed as motor rollers that are rotationally driven in the discharge direction Y by electromagnetic action like a motor, and the remaining rollers 9e are free rollers that rotate freely. The lift base 9a is provided with left and right guide plates 9f on both axial ends of the plurality of rollers 9e. Each guide plate 9f accurately guides the block of the game board 1 conveyed by the roller 9e in the discharge direction Y.
[0016]
Transshipment machine Structure 10 includes a seesaw 10 a attached to the lower part of the apparatus main body 4. The seesaw 10a is actuated like an air cylinder attached to the apparatus body 4. Due The rotor 10b swings up and down around the shaft member 10c. A drive roller 10d, a free roller 10e, a stopper 10f, and a sensor 10g are provided at the tip of the seesaw 10a that protrudes forward and outward from the inside of the apparatus main body 4.
[0017]
A block in which a predetermined number of game boards 1 are stacked is formed on the lifter 9 of this embodiment, and when the lift base 9a reaches the lower limit position, the tip of the seesaw 10a rises to the upper limit position indicated by the solid line, The drive roller 10d is driven to rotate in the same direction as the roller 9e of the lifter 9 in the same direction, so that the block of the game board 1 passes from the lifter 9 to the drive roller 10d and the free via the relief roller 12 attached to the device body 4. Transport to roller 10e. The operator confirms that the rotation of the drive roller is stopped immediately before or immediately before the block comes into contact with the stopper 10f, and that the block of the game board 1 has been carried out of the apparatus by the block discharge completion notification display means (not shown). To inform.
[0018]
By this notification, the operator inserts the transport carriage 11 into a space formed below the tip of the seesaw 10a at the ascending limit position, and the sensor 10g detects the transport carriage 11 in the transport carriage 11 so that After the outer striker fixes the position of the transport carriage 11 with respect to the apparatus main body 4, the tip of the seesaw 10a descends from the ascending limit position to the descending limit position. In the middle of the descent, the block of the game board 1 on which the seesaw 10a is mounted at the tip is transferred to the mounting portion 11a raised from the left and right of the transport carriage 11.
[0019]
Reference numeral 13 in FIG. 1 is assembled to the apparatus main body 4 in the longitudinal direction from the transport mechanism 5 side behind the lift base 9a. Ru The board guide 13 prevents the collapse of the block of the game board 1 when the lift base 9a is lowered. Further, in FIG. 1, a substrate guide (not shown) having a low height is provided on the front side of the apparatus main body 4 corresponding to the substrate guide 13, and the substrate guide (13) and the substrate guide 13 (not shown) are provided between them. The game board 1 that falls further is guided to drop horizontally, and the game board 1 is mounted on the lift base 9a.
[0020]
The operation of this embodiment will be described with reference to FIGS. In the state where the movable plate 5b of the transport mechanism 5 is stopped at the forward limit position and the game board 1 is transported in the transport direction X from the transport line 2 via the transport mechanism 5, the defect detection outside the figure is detected. When the device outputs a defect detection signal, and the gaming board 1 recognized as the defect from which the defect detection signal is output is placed on the roller 5c along the movable plate 5b and reaches the defect discharge space 3, FIG. As shown in FIG. 2, the game board 1 comes into contact with the board stopper 6 protruding on the transfer path, and the transfer of the game board 1 is restricted.
[0021]
Next, as shown in FIG. 3, the receiving plate 7b of the delivery mechanism 7 moves forward and enters below the front-rear direction of the game board 1 on the roller 5c.
[0022]
Thereafter, as shown in FIG. 4, the movable plate 5b moves backward, the roller 5c escapes from the game board 1, and the game board 1 is supported by the receiver 7b.
[0023]
Subsequently, as shown in FIG. 5, the receiver 7b moves backward. At the time of the retreat, the abutting bar 7c corresponds to the side surface in the front-rear direction of the game board 1. Therefore, even if the game board 1 tries to accompany the receiving body 7b, the game board 1 contacts the abutting bar 7c. The game board 1 is prevented from being brought together, and the game board 1 falls from the receiving plate 7b while maintaining the horizontal plane as shown by the phantom line from the solid line shown in FIG. 5b. It is mounted on the roller 9e of the lift base 9a stopped at the receiving position. When the game board 1 is already mounted on the lift base 9a, the lift base 9a receives the game board on which the uppermost game board 1 is mounted on the receiving plate 7b of the delivery mechanism 7. Each time the gaming board 1 that is recognized as defective is discharged, it is controlled by the rotational drive amount of the motor 9b that takes into account the thickness of one gaming board 1 so as to be in a fixed position that is close to a range that does not interfere with 1. Is done. Further, the board stopper 6 shown in FIG. 3 does not obstruct the passage of the normal game board 1 if the next normal game board 1 moves back to the defective discharge space 3 after the game board 1 is stopped. For example, if the gaming board 1 that is recognized as defective is dropped from the receiver 7b to the lift base 9a and then retracted, the board stopper is used when the defective gaming board 1 drops from the receiver 7b to the lift base 9a. 6 serves as positioning, and the game board 1 can be accurately stacked on the lift base 9a.
[0024]
And as shown in FIG. 6, the lift base 9a which received the game board | substrate 1 descend | falls to a retracted position. In the retracted position, the game board 1 indicated by a solid line that is detected as a failure mounted on the lift base 9 a does not interfere with the transport mechanism 5 and the delivery mechanism 7. While the lift base 9a is lowered, the game board 1 is guided by the board guide 13 so as not to collapse. When the game board 1 is already mounted, the retraction position of the lift base 9a is fixed as high as possible within a range in which the uppermost game board 1 does not interfere with the transport mechanism 5 and the delivery mechanism 7. The position is controlled by the rotational driving amount of the motor 9b in consideration of the thickness of one gaming board 1 for each defective discharging operation of the gaming board 1 so as to be positioned.
[0025]
Thereafter, the movable plate 5b of the transport mechanism 5 stops from the backward limit position to the forward limit position, and returns to the normal state in which the game board 1 from the transport line 2 is transported in the transport direction X. This normal state is a mode in which the substrate stopper 6 is stopped at the retreat limit position and retracted from the transport path of the game board 1 in FIG.
[0026]
By repeating the steps shown in FIGS. 2 to 6 each time a defect is detected, a predetermined number of game boards 1 are stacked on the lift base 9a, and each time the lift is lowered by the thickness of one game board 1. When the upper transport portion of the roller 9e in the base 9a reaches a lower limit position that is substantially the same height as the upper transport portion of the drive roller 10d of the discharge mechanism 10 at the upper limit position, as shown in FIGS. An operator inserts the transport carriage 11 into a space below the tip of the seesaw 10a.
[0027]
Then, after a striker (not shown) fixes the position of the transport carriage 11 with respect to the apparatus main body 4, the roller 9 e and the drive roller 10 d are rotationally driven to convey a block in which a predetermined number of game boards 1 are stacked in the discharge direction Y. When the block is transferred from the lift base 9a to the tip of the seesaw 10a as shown by the phantom line in FIG. 7, the seesaw 10a descends from the ascending limit position to the descending limit position. The block is delivered from the tip of the seesaw 10a to the mounting portion 11a of the transport carriage 11. In this state, the operator pulls the transport carriage 11 forward of the seesaw 10a and stores it in a predetermined defective material reservoir.
[0028]
In short, according to the configuration of this embodiment, when the gaming board 1 recognized as defective is transferred from the transfer line 2 to the transfer mechanism 5 and received by the substrate stopper 6 in the defect discharge space 3, it is stopped. The receiver 7b sinks under the game board 1. Then, when the movable plate 5b of the transport mechanism 5 is retracted, the game board 1 falls from between the front and rear directions of the roller 5c of the transport mechanism 5 and is received by the receiver 7b. Thereafter, when the receiving body 7b moves backward and the game board 1 falls from between the front and rear directions of the receiving body 7b, the abutment bar 7c of the delivery mechanism 7 prevents the game board 1 from being accompanied with the receiving body 7b. The gaming board 1 can be dropped horizontally. The falling gaming board 1 is mounted on a lift base 9a that is stopped at the receiving position closest to the receiving body 7b below, and the gaming board 1 collides with other parts at an acute angle and is damaged when dropped. Can be eliminated. In parallel with this mounting, the board stopper 6 stops at the retreat limit position, and the movable plate 5b of the transport mechanism 5 returns to the advance limit position, so that one gaming board 1 that is recognized as defective is used for manufacturing a gaming machine. One operation of discharging from the transport line 2 is completed. This discharging operation is repeated every time the gaming board 1 transported by the transport line 2 is recognized as defective, whereby a predetermined number of gaming boards 1 recognized as defective are stacked on the lift base 9a to block. When formed, the roller 9e of the lifter 9 and the drive roller 10d of the transshipment mechanism 10 can be rotationally driven in the same direction at the same speed, and the block can be discharged out of the apparatus. This discharged block can be transferred from the reloading mechanism 10 to the transporting carriage 11 and transported to the defective material reservoir for storage.
[0029]
In the above-described embodiment, the game board 1 on which the design drawing is drawn is illustrated and described. For example, a game board in which a cell sheet on which a design drawing is drawn is coupled to one surface of the game board 1 is replaced with the game board 1. However, the same applies. In this case, it will be apparent that the game board 1 of the above embodiment can be implemented by replacing it with a game board. In addition, the design drawing is drawn on the game board means that the design drawing is directly printed on one surface of the game board 1 or the cell sheet on which the design drawing is printed is bonded to one surface of the game board 1. included.
[0030]
Further, the discharge mechanism 8 may be formed like a shooter that slides the game board 1 or the game board dropped from the transport mechanism 5 obliquely downward.
[0031]
Of course, the present invention can be applied to a structure in which one or both of the delivery mechanism 7 and the substrate stopper 6 are omitted.
[0032]
In the above-described embodiment, when the game board 1 stays in the processing area downstream of the defective discharge space 3, the board stopper 6 is projected onto the transport path of the game board 1 by the roller 5c of the transport mechanism 5, The normal game board 1 is stopped on the roller 5c, and when the stay of the game board 1 in the downstream processing area is eliminated, the board stopper 6 is retracted from the transfer path and is stopped. If the board stopper 6 is operated in relation to the staying state of the game board 1 in the downstream processing area, such as flowing a normal game board 1 to the downstream processing area, the work in the downstream processing area is performed. Can also be improved.
