【発明の属する技術分野】
本発明は、鉛蓄電池用極板群の電槽への挿入法並びに挿入装置に関する。
【０００２】
【従来の技術】
従来、鉛蓄電池用極板群を電槽に挿入するに当たり、極板群を電槽内に収容したときその厚さ方向に適度な群圧を生ずるようにするため、極板群をそのまゝ、或いはその両端板の外面に１枚又は２，３枚のスペーサーを積層して、その厚みを、挿入すべき電槽の厚さ方向の対向壁間の内寸法よりも大きい寸法としたものを、電槽に手作業により或いは機械力により上方から大きな押圧力をかけて電槽に押圧することが行われているが、極板群の下端部は電槽の開口部に入りにくく、挿入作業が非能率となり、また、極板群を一挙に電槽に押圧挿入しようとするので、特に、極板群の両端板が電槽の対向壁部に当たり、挿入が阻止されたとき、極板又はスペーサーから成る両端板は折れ曲がり、いわゆる座屈を生じ、生産性が低下する不都合がしばしばであった。
また、電槽の開口部の口縁に、極板群の厚さ方向に対向する内面が上方に至るに従いテーパー状に広がった傾斜面に形成された案内板を嵌着し、該極板群を該案内板を介してピストンシリンダーにより上方から挿入することにより、挿入作業能率を向上せしめるようにすることも公知である。
【０００３】
【発明が解決しようとする課題】
しかし乍ら、上記の公知手段のように、電槽側を固定した状態で極板群を上方から加圧して電槽に一挙に押圧挿入することは、案内板を介しても、その挿入作業中に極板群の両端板が座屈することがしばしば生ずることは不可避である。
かゝる不都合に鑑み、発明者は、従来とは全く異なる押圧挿入手段により、上記の技術の課題を解決することを目的とする。
【０００４】
【課題を解決するための手段】
本発明は、上記の課題を解決し、極板群の両端板の座屈を防止して鉛蓄電池の生産性を向上した鉛蓄電池用極板群の電槽への挿入法を提供するもので、（ａ）往復動自在の一対のワークホルダーにより極板群の下部を挟持した状態で、該極板群の該一対のワークホルダーより下方に突出する電槽へ挿入すべき高さ部分を、該極板群の直下に位置し且つ昇降自在に保持された電槽を上昇させて往復動自在で且つ上下動自在の一対のガイドホルダーの先端に具備した一対のガイド片を介し電槽に挿入する一方、電槽の上昇に伴い該一対のガイドホルダーを上昇せしめる工程と（ｂ）次いで、該一対のワークホルダーによる極板群の下部の挟持を解除した状態で、電槽を下降させて該電槽の下降に伴い下降する極板群の一部を該一対のワークホルダーの位置より下方へ次の電槽へ挿入すべき高さ部分として引き出す一方、電槽の下降に伴い該一対のガイドホルダーが下降する工程と、（ｃ）その後、該（ａ）工程と該（ｂ）工程を極板群の大部分が電槽に挿入されるまで繰り返し行うことを特徴とする。
更に本発明は、座屈を生じない上記の挿入法を更に容易になし得られる挿入法を提供するもので、極板群の下端を、電槽に挿入するときにのみ、極板群の下端部を該一対のガイド片を具備した上下動自在の該一対のガイドホルダーにより圧縮することを特徴とする。更に本発明は、上記の挿入法において、電槽に所望の圧迫力で極板群を収容し得る挿入法を提供するもので、両端面にスペーサーを積層して成る極板群を用い、請求項１又は２に記載の挿入法を行うことを特徴とする。
更に本発明は、極板群の電槽への挿入に当たり、両端板に座屈を生じない鉛蓄電池用極板群の電槽への挿入装置を提供するもので、極板群を位置決め収容する空間を規制する位置合わせ装置と、極板群の厚さ方向で対向し、位置決めされた極板群の下部に対応する高さ位置に配設され且つピストン杆を具備したワークホルダーと、該一対のワークホルダーの下方に高さスペースを存して極板群の下端部に対応する高さ位置に配設され且つ先端にガイド片を支持したピストン杆を具備すると共に該高さスペース内で上下動自在の一対のガイドホルダーと、該位置決めされた極板群の直下に、電槽を載置固定し且つ昇降自在に支持する昇降台を昇降杆の上端に具備した昇降装置とから成ることを特徴とする。
更に本発明は、上記の挿入装置において、スペーサーと積層した極板群を電槽へ挿入する挿入装置を提供するもので、該位置合わせ装置に具備した極板群の厚さ方向に配設された一対の位置合わせ具の互いに対向する面にスペーサー挿入用溝枠を設けたことを特徴とする。
【０００５】
【発明の実施の形態】
本発明の実施の態様の１例を添付図面の図１乃至図９を参照し説明する。
図面で１は、機筐２に設けた本発明の鉛蓄電池用極板群の電槽への挿入装置の１例を示す。該機筐２は、床面に設置された昇降装置取り付け用筐型基台２ａと該基台２ａの前後方向の後部側に立設した背面壁２ｂ１と天板２ｂ２を有し、前面を開放した筐型囲枠２ｂとから成る。該筐型囲枠２ｂの前面の上半部に、矩形状板材の中央部に下端に開放した切欠部３ａを形成された下向きのコ字状板３を取り付けると共に、該コ字状板３の前面の左右に、該機筐２の中心部を通る垂直線Ｃを通る前後方向の垂直面に対し左右に等間隔の位置で且つ対称的に極板群の厚さ方向の位置決めを行う一対の位置決め具４ａ，４ｂを、その夫々に具備したサーボモータ５ａとボールネジ５ｂと該コ字状板３に穿設した水平方向に延びる長孔３ｂを挿通し、且つ各位置決め具に連結する連結部材５ｃとから成る駆動装置５，５の駆動により、即ちその各該サーボモータ５ａの正転、逆転により、該コ字状板３の内面の左右において、上下段に水平方向に平行に敷設した各案内レール６，６上を往復動走行して互いに近づき或いは遠のくように配設した。尚、これらの位置決め具４ａ，４ｂは、底壁と両側壁と前壁とから成り、且つ背面が開放したフレーム状囲枠で構成することが好ましく、これにより往復動走行が軽快に行われるようにした。また、その下向きのコ字状板３の前方に、該垂直線Ｃを通る幅方向の垂直面に対し前後方向に等間隔の位置に該コ字状板３と同じ形状の下端を開放した切欠部７ａを形成された下向きのコ字状板７を、該板３の四周縁から前方に水平に延びる複数本の所定長さの連結杆８，８，…を介して設け、かくして構成された互いに前後に対向して配設された前側のコ字状板７と後側のコ字状板３の夫々の内側に対向して、図面で仮想線で示す極板群Ｇの幅方向における位置決めを行うための極板群Ｇの厚さ方向にその厚さより長手で且つ水平に延びる長杆から成るサイド位置決め具９ｃ及び９ｄを前進後退動自在に夫々配設する。更に詳細には、そのサイド位置決め具９ｃは、前側のコ字状板７の外面に取り付けたピストンシリンダー１０ｃのピストン杆と該コ字状板７に設けた貫通孔を介して連結されており、かくして、そのピストンシリンダー１０ｃの駆動により前進後退動せしめられるようにした。図面で１０ｅは、該ピストンシリンダー１０ｃの左右に位置し、且つ該コ字状板７に取り付けられ且つ該位置決め具９ｃに連結せしめられた案内杆を示し、これにより該位置決め具９ｃが該ピストンシリンダー１０ｃの駆動により前進後退動において、水平移動を確保するようにした。同様に、サイド位置決め具９ｄは、後側のコ字状板３の外面に取り付けたピストンシリンダー１０ｄのピストン杆と該コ字状板３に設けた貫通孔を介して連結されており、かくして、そのピストンシリンダー１０ｄの駆動により前進後退動せしめられるようにした。尚、図示を省略したが、該ピストンシリンダー１０ｄの左右に前記と同様に左右の案内杆を配設する。
更に、該後側のコ字状板３の切欠部３ａに対し直交して極板群Ｇの底面を受けて位置決め載置せしめる位置決め用ベースプレート１１を、ピストンシリンダー１２により前後方向に駆動するようにし、後退位置では、該ベースプレート１１は、前記の筐型囲枠２ｂの室内１３に仮想線で示すように収容されており、前進位置では、後側のコ字状板３と前側のコ字状板７との間に形成された空間１７内に前進し、実線示で示すように、その上面で位置決めされる極板群Ｇの底面を受け止めるようにした。（図５参照）。而して、該ベースプレート１１は、図４及び図５に明示のように、極板群Ｇの厚さよりも充分広幅であり、且つその前進位置においてそのベースプレート１１の前部で極板群Ｇを載置し得るような長手の板状体から成る。１４はベースプレート１１の下面に設けた左右一対の案内レール、１５は案内レール１４に接するスライドベアリングを示す。
更に詳細には、該ベースプレート１１は上面を水平面とし、下面を後端から前端に至るに従い漸次肉薄となり前方へ至るに従い上向きの傾斜面とし、該ベースプレート１１の下面に設けた支持台１６の上面を該傾斜面と平行する傾斜面上に敷設したレール１４，１４上を走行自在とし、図５に示すように、極板群Ｇの下面を支承した前進位置から後部の筐型囲枠の室１３内に仮想線示のように後退するとき、ベースプレート１１は斜め下方に下がり乍ら後退するようにし、これにより、ベースプレート１１の該後退時に極板群の下端面から直ちに離れて該極板群Ｇに不要な摩擦や応力がかゝることを防止するようにした。１６ａは、支持台１６を裏面から支承する左右一対の補強板を示す。
【０００６】
かくして、前記の左右の位置決め具４ａ，４ｂと前後のサイド位置決め具９ｃ，９ｄを具備した前後のコ字状板３，７とその下方前進後退動のベースプレート１１とにより底面及び四周側面を囲繞される極板群位置決め用空間部１７内に外部から搬送用治具により把持された電槽へ挿入すべき極板群Ｇをその空間部１７の上方から挿入し、その極板群Ｇを前進した該ベースプレート１１の上面に載置すると共に、その厚さ方向は、左右の位置決め具４ａ，４ｂを互いに前進させて、図４に示すように、極板群の両端板に軽く接するか、或いはこれとの間に僅かな間隔を存して左右方向を位置決めする一方、その幅方向即ち、前後方向は、図５に示すように、ピストンシリンダー１０ｃ，１０ｄを駆動してその前後のサイド位置決め具９ｃ，９ｄを前進させて極板群のセパレータ群の両側縁に軽く接するか、或いはこれとの間に僅かな間隙を存してその前後方向の位置決めして、図５に示すように所定の位置に極板群Ｇを位置決めするようにした。
【０００７】
更に、本発明によれば、左右の位置決め具４ａ，４ｂの下方に、上記のように極板群Ｇを位置決めした後、その極板群Ｇをその積層方向の両端面を左右から加圧し挟持するためのワークホルダー１８ａ，１８ｂを配設する。左右のワークホルダー１８ａ，１８ｂは、夫々ピストンシリンダーから成り、図示の例では、夫々のシリンダー部で左右の位置決め具４ａ，４ｂの下面に、左右の位置決め具４ａ，４ｂの夫々の幅方向の中央部に固設され、夫々のピストン杆の先端に、極板群Ｇの幅の少なくとも全長に亘り水平に延びる長手の加圧板１９ａ，１９ｂを具備している。かくして、左右のワークホルダー１８ａ，１８ｂのピストン杆の前進により、その加圧板１９ａ，１９ｂにより極板群Ｇの高さの中間より下方を挟持するようにした。
【０００８】
更に、本発明によれば、左右のワークホルダー１８ａ，１８ｂの下方に、位置決めされた極板群Ｇの下端から僅か上方に位置して、例えば下端から５〜１０ｍｍ程度の高さスペースｈを存した位置に先端にガイド片２０ａ，２０ｂを垂れ下げた状態に具備せしめたピストンシリンダーから成るガイドホルダー２１ａ，２１ｂを配設し、その左右のピストン杆の前進によりその先端のガイド片２０ａ，２０ｂは、極板群Ｇの下端よりも下方に所望長さ垂れ下がる垂れ下がり部が、後記する電槽Ｂの上昇過程で、該左右のガイド片２０ａ，２０ｂは、極板群Ｇの両端面と電槽の左右の対向側壁ｂ，ｂとの間に介入し挟持され得るようにし、また、同時に、該ガイドホルダー２１ａ，２１ｂにより極板群の下端部を加圧し、その厚さを圧縮し電槽への挿入を更に容易になし得るようにした。更に詳細には、その夫々のピストン杆の先端に極板群の少なくとも幅全長に亘り水平に延び且つ先端を円弧状面としたガイド片取付部材２２ａ，２２ｂを設け、その左右のガイド片取付部材２２ａ，２２ｂの上面に基部をネジ止めなどの固定具２３，２３によりその幅方向に適宜の間隔を存して鋲着され、その遊離部を該ガイド片取付部材２２ａ，２２ｂの先端から極板群Ｇの下端よりも下方へ所望長さ垂れ下げてた垂れ下がり部を有するガイド片２０ａ，２０ｂを具備せしめたものである。該ガイド片２０ａ，２０ｂは、例えばステンレス板を材料とし、ガイド片取付部材２２ａ，２２ｂと同じ幅方向の長さを有し且つその先端から下方へ図示のように垂れ下がる縦方向の幅を有する長矩形帯状に形成したものであり、ガイド片２０ａ，２０ｂとしては、平滑で極板群の両端板を滑らかに案内するシート面を有するものが好ましく用いられる。
【０００９】
尚、図示の例では、左右のガイドホルダー２１ａ，２１ｂは、左右のワークホルダー１８ａ，１８ｂの下方に所定の高さスペースＨを存した位置に設置すると共にその高さスペースＨ間を上下動自在に次のように配設した。即ち、左右の位置決め具４ａ，４ｂの１側から下垂する下垂壁４ａ１，４ｂ１面に取り付けられた所定の長さ（高さ）を有する垂直板２４ａ，２４ｂと該垂直板２４ａ，２４ｂの下端から直角に折れ曲がるストッパー２５ａ，２５ｂとを配設し、その左右の垂直板２４ａ，２４ｂに夫々形成した嵌合用垂直案内凹条又は凸条２６ａ，２６ｂ（図示では凸条）に、左右のガイドホルダー２１ａ，２１ｂのシリンダー部に固着したＬ字状の板２７ａ，２７ｂに形成した嵌合用垂直案内凸条又は凹条２８ａ，２８ｂ（図示では凹条）を摺動自在に嵌合せしめ、該左右のガイドホルダー２１ａ，２１ｂの夫々のシリンダー部を左右の該Ｌ字状の板２７ａ，２７ｂ上に固設した。かくして、左右のガイドホルダー２１ａ，２１ｂは、互いに嵌合する垂直案内凹凸条を介し、該ストッパー２５ａ，２５ｂとその上方のワークホルダー１８ａ，１８ｂのシリンダー部との間をその夫々の所定の高さスペースＨ，Ｈに対応する一定の距離を上下方向に往復動自在に配設した。
【００１０】
一方、該機筐２の筐型基台２ａには、該機筐２の中心軸Ｃ線上に前記の極板群位置決め用空間１７内に位置決めされた極板群Ｇの直下に、電槽昇降装置２９を設ける。該装置２９の駆動部は、その中心軸Ｃ線上に該筐型基台２ａの台板２ａ１の裏面に取り付けたサーボモータ３０と、該サーボモータ３０により駆動される無端ベルト３１から成り、該ベルト３１は、該台板２ａ１の中心を貫通するロータリーボールスクリュー杆３２に接続されている。該ロータリーボールスクリュー杆３２の前後左右に等間隔を存して４本の昇降杆３３ａ，３３ｂ，３３ｃ，３３ｄを該台板２ａ１を貫通して配設し、そのロータリーボールスクリュー杆３２とこれら昇降杆の上端に電槽載置台３４を具備して電槽昇降装置２９が構成されている。かくして、サーボモータ３０の正転により該無端ベルト３１の往動走行と該ロータリーボールスクリュー杆３２の正転を介し電槽載置台３４は昇降し、サーボモータ３０の逆転を介し該電槽載置台３４は下降するようにした。
【００１１】
該電槽昇降装置２９は、その電槽載置台３４に載置した仮想線で示す電槽Ｂを固定自在に保持するべく、電槽クランプ装置３５を設ける。該電槽クランプ装置３５は、該載置台３４の中心に対し等しい距離に配置された左右のクランプ板３５ａ，３５ｂと前後に配設されたクランプ板３５ｃ，３５ｄとから成り、且つその各クランプ板３５ａ，３５ｂ，３５ｃ，３５ｄは、載置台３４上に配置したピストンシリンダー３６，３７の駆動により、寸法の異なる電槽に応じて夫々のクランプ板により前後左右から挟持固定するようにした。
更に詳細には、前後に対向配置されたクランク板３５ｃ及び３５ｄのうち、一方のクランク板、図示の後側のクランク板３５ｄは、該ピストンシリンダー３６により前後動自在に駆動されるようにした。また、左右に対向配置されたクランク板３５ａ，３５ｂは互いにラックアンドピニオン３８により連動せしめられると共に、該ピストンシリンダー３７のピストン杆３７ａをその先端に直角に延びる連結杆３９を介してクランク板３５ｂに連結せしめるように構成し、該ピストンシリンダー３７のピストン杆３７ａの収縮伸長に伴い、対向する左右の該クランク板３５ｂ及びクランク板３５ａを前記のラックアンドピニオン３８の連動と共に互いに接近及び離隔する往復動を行うようにした。３８ａは、ラックアンドピニオン取付けベースを示す。
【００１２】
更に、該電槽昇降装置３４は、その側方に前後方向に台板２ａ１上に設置した一軸ロボット機構４０の駆動により往復動走行する連結部材４０ａを介し前後方向に載置台２ａ１に左右に敷設した案内レール４１，４１上を走行せしめられるようにした。かくして、電槽Ｂを載置固定するときは、図１、図２及び図３に示すように電槽昇降装置３４を前進させてこれを該筐型基台２ａの前部に、前記の極板群位置決め囲枠の前方の上面開放空間位置まで前進させ、人手又はロボットにより電槽Ｂを載置固定し、載置固定後、後退させ、図４及び図５に示すように、上方の位置決めされた極板群Ｇの直下に電槽Ｂをその中心垂直軸線Ｃ上に整合させて停止させるようにした。
【００１３】
次に、上記の鉛蓄電池用極板群の電槽挿入装置を用いた挿入法を説明する。
図示しない外部の極板群搬送治具により把持された極板群Ｇを、前記装置の該ベースプレート１１を前進させ、その上方の左右の位置決め具４ａ，４ｂと前後の位置決め具９ｃ，９ｄを具備した前後のコ字状板３，７とにより囲繞された空間１７内に挿入し、該ベースプレート１１上に載置する。
この状態で、左右の位置決め具４ａ，４ｂを前進させ、その極板群Ｇの両端板との間に僅かな間隙を存して極板群Ｇの厚さ方向の位置決めを行う一方、前後の位置決め具９ｃ，９ｄを前進させ極板群Ｇの両側面のセパレータＳに軽く接触させるか、僅かな間隔を存して、その前後方向の位置決めを行い極板群の位置決め作業を完了する。
【００１４】
次いで左右のワークホルダー１８ａ，１８ｂのピストン杆を前進させ、その先端の加圧板１９ａ，１９ｂにより、位置決めされた極板群Ｇを挟持する。その後、該ベースプレート１１を後退させるが、そのベースプレート１１を後退させる前又は後に、左右のガイドホルダー２１ａ，２１ｂのピストン杆を前進させ、その先端の左右のガイド片２０ａ，２０ｂを極板群Ｇから上記のように１０〜５０ｍｍ程度上方に位置する下端近傍の両面に近接させるか圧接させ、後記するように、極板群Ｇ直下の昇降装置の電槽載置台に載置した電槽Ｂが上昇する過程で、その厚さ方向で対向する電槽側壁の上端の上方に左右のガイド片２０ａ，２０ｂの下面に対応する位置にガイド片２０ａ，２０ｂを配置する。この場合、所望に応じ、極板群Ｇの下端部の両端面を左右のガイドホルダー２１ａ，２１ｂのガイド片取付板２２ａ，２２ｂにより該隣接させたガイド片２０ａ，２０ｂを介し加圧し、極板群Ｇの下端部を圧縮した状態としてもよい。
このように、極板群Ｇを少なくとも左右のワークホルダー１８ａ，１８ｂで挟持した後、該ベースプレート１１を図５に示す仮想線示のように、機筐２の後部室１３内に後退せしめる。
【００１５】
一方、電槽昇降装置２９は、不使用時には通常該筐型基台２ａの前部に位置せしめておき、使用時には、その電槽載置台３４上に、上記の極板群を圧迫収容するに適した電槽Ｇを載置すると共に電槽クランプ装置３５内に収容し、夫々のクランプ板３５ａ，３５ｂ，３５ｃ，３５ｄにより前後左右から挟持して電槽Ｇを不動に設置した後、一軸ロボット機構４０を駆動して該電槽昇降装置２９を後退させ、上方の位置決めされた極板群Ｇの直下に、図４及び図５に示すように、その中心の垂直軸線Ｃ上に位置せしめる。
【００１６】
次いで、前記のサーボモータ３０を正転させて、無端ベルト３１を介して該ロータリーボールスクリュー杆３２を正転させて、４本の昇降杆３３ａ，３３ｂ，３３ｃ，３３ｄと共に上昇させ、電槽Ｂを支持した載置台３４を上昇させ、左右のガイド片２０ａ，２０ｂの垂れ下がり部が該電槽Ｂの対向壁ｂ，ｂの内側に臨ませ極板群Ｇの下端との間に介入する状態とし、この状態で引き続き電槽Ｂを上昇させるときは、先ず極板群Ｇの下端が左右のガイド片２０ａ，２０ｂに案内されて電槽Ｂ内に挿入され、次いで該電槽Ｂの対向壁ｂ，ｂは左右のガイド片取付板２２ａ，２２ｂの下面に当接せしめる。次いで、ガイドホルダー２１ａ，２１ｂの押圧をシリンダー部の押圧を開放させることにより解除し、この状態で更に電槽Ｂを上昇させると、これに伴い左右のガイドホルダー２１ａ，２１ｂも電槽Ｂの上昇に伴い押し上げられて、該左右のガイドホルダー２１ａ，２１ｂがその上方の左右のワークホルダー１８ａ，１８ｂに当接したとき電槽Ｂの上昇を止める。即ち、所定の高さスペースの距離Ｈ上昇したとき電槽Ｂの上昇を停止する。この電槽Ｂの上昇過程で、極板群Ｇの下端部は、その両端面を該左右のガイド片２０ａ，２０ｂの内面に摺接し案内されて電槽Ｂ内に円滑に挿入される。この場合、極板群Ｇの電槽Ｂへの挿入分は、上記の高さスペースＨに対応する極めて短い高さ分Ｈであるので、即ち、極板群Ｇの下端から極板群Ｇを挟持する左右のガイドホルダー２１ａ，２１ｂが、該左右のワークホルダー１８ａ，１８ｂに当接するまでの短い高さ分であるので、極板群Ｇの両端板の座屈なく、円滑且つ確実に電槽に挿入することができる。尚、この場合、予め、極板群Ｇの下端部を左右のガイドホルダー２１ａ，２１ｂにより加圧し、その厚さを圧縮せしめたときは、極板群Ｇの両端面とガイド片２０ａ，２０ｂとの摩擦が減少するので、極板群Ｇの下端の挿入が更に容易になし得られる。従ってこの場合は、極板群Ｇの下端が電槽Ｂに挿入された後に、左右のガイドホルダー２１ａ，２１ｂのピストン杆を少なくとも少許後退させてその圧縮を解き、その後の引き続く電槽Ｂの上昇に伴い上昇する該ガイドホルダー２１ａ，２１ｂが該左右のワークホルダー１８ａ，１８ｂに当接するまで上昇させて電槽Ｂの上昇を停止する。かくして、上記の高さスペースＨに対応する極板群Ｇの下端部の挿入が完了する。（図６及び図７参照）。
【００１７】
次いで、上記の極板群Ｇを挟持している左右のワークホルダー１８ａ，１８ｂのピストン杆を後退させてその挟持を解いた後、尚、前後の位置決め具９ｃ，９ｄが極板群Ｇの両側のセパレータに接触している場合は、そのまゝ、或いは後退させて非接触状態とした後、電槽Ｂを下降させる。該左右のガイド片２０ａ，２０ｂの下垂部は、図６に明示のように、電槽Ｂの左右の対向側壁ｂ，ｂと該電槽Ｂ内に圧縮挿入された極板群Ｇの下端部との間に挟まれた状態にあるので、電槽Ｂの下降に引き連られて極板群Ｇと該左右のガイド片２０ａ，２０ｂも下降し、従って同時に、該左右のガイド片２０ａ，２０ｂを保持する左右のガイドホルダー２１ａ，２１ｂも下降する。かくして、該左右のガイドホルダー２１ａ，２１ｂが下方のストッパー２５ａ，２５ｂに当接したもとの下降位置まで下降し停止する。即ち、前記の高さスペースＨだけ下降する。電槽Ｂがこの高さスペースＨに対応する距離下降したとき下降を停止する。この電槽Ｂを前記の高さスペースＨに対応する分だけ下降させる電槽下降工程により、極板群Ｇをこの高さスペースＨに相当する高さ分だけ下降せしめる。（図８参照）。
【００１８】
次いで、再び、前記の左右のワークホルダー１８ａ，１８ｂを前進させて極板群を挟持した後、電槽Ｂを再び上昇させ、電槽Ｂの上昇に伴い左右のガイド片２０ａ，２０ｂと左右のガイドホルダー２１ａ，２１ｂも押し上げられて上昇し、左右のガイドホルダー２１ａ，２１ｂが上方の左右のワークホルダー１８ａ，１８ｂに当接したところで、電槽Ｂの上昇を停止させる。この電槽ｂの上昇工程により、極板群Ｇを前記と同じ所定の高さスペースＨに相当する高さ分Ｈだけ電槽Ｂ内に挿入する電槽上昇工程と、次いで、再び前記の左右のワークホルダー１８ａ，１８ｂによる極板群Ｇの挟持を解いた後、電槽Ｂを再び前記の高さスペースＨに相当する分下降させて、該電槽Ｂの下降に伴い極板群Ｇの次に挿入すべき高さ分、即ち、前記の高さスペースＨに相当する高さ分下方へ引き出す電槽下降工程を繰り返し行う。例えば、高さ寸法３５５ｍｍを有する極板群Ｇを電槽Ｂへ挿入する場合、上記のガイドホルダー２１ａ，２１ｂの上下動するストローク、即ち、高さスペースＨを７０ｍｍとしたとき、電槽の上昇により極板群が電槽に挿入される高さ分は７０ｍｍとなり、電槽の下降により極板群の挿入すべき高さ分として７０ｍｍ下方へ引き出されるので、電槽の上昇、下降工程を４回繰り返すことにより２８０ｍｍ電槽に挿入されることゝなる。このように、本発明によれば、電槽の上昇工程と下降工程を極板群Ｇの座屈を生じない短い距離Ｈ、図示の例では、僅か７０ｍｍの短い高さ距離Ｈを左右のガイド片２０ａ，２０ｂを介して電槽Ｂへの挿入を繰り返すようにしたので、極板群Ｇの両端板の座屈を生ずることなく円滑且つ良好に挿入することができる。かゝる挿入操作を繰り返した後、高さが僅か７５ｍｍの極板群の上端部が電槽Ｂの上方に未挿入状態として残ることゝなる（図９参照）ので、極板群Ｇを電槽Ｂ内に完全に収容するため、極板群押下げ装置により次のように行う。

These positioning tools 4a and 4b are preferably composed of a frame-like frame having a bottom wall, both side walls, and a front wall, and the back surface being opened, so that reciprocating travel can be performed easily. I made it. Also, a notch having an open lower end of the same shape as the U-shaped plate 3 at a position equidistant in the front-rear direction with respect to a vertical plane in the width direction passing through the vertical line C in front of the downward U-shaped plate 3 The downward U-shaped plate 7 in which the portion 7a is formed is provided via a plurality of connecting rods 8, 8,... Of a predetermined length extending horizontally from the four peripheral edges of the plate 3 in this way. Positioning in the width direction of the electrode plate group G indicated by an imaginary line in the drawing so as to face the inside of each of the front U-shaped plate 7 and the rear U-shaped plate 3 arranged to face each other in the front-rear direction. In the thickness direction of the electrode plate group G for performing the above, side positioning tools 9c and 9d made of long rods that are longer than the thickness and horizontally extend are arranged so as to be movable forward and backward. More specifically, the side positioning tool 9c is connected to a piston rod of a piston cylinder 10c attached to the outer surface of the front U-shaped plate 7 through a through hole provided in the U-shaped plate 7. Thus, the piston cylinder 10c is driven to move forward and backward. In the drawing, reference numeral 10e denotes a guide rod located on the left and right of the piston cylinder 10c and attached to the U-shaped plate 7 and connected to the positioning tool 9c, whereby the positioning tool 9c is connected to the piston cylinder 10c. The horizontal movement is ensured in the forward and backward movement by driving 10c. Similarly, the side positioning tool 9d is connected to the piston rod of the piston cylinder 10d attached to the outer surface of the rear U-shaped plate 3 through a through hole provided in the U-shaped plate 3, and thus, The piston cylinder 10d is driven to move forward and backward.

Next, the insertion method using the battery case insertion device for the electrode plate group for the lead storage battery will be described.
An electrode plate group G held by an external electrode plate group conveying jig (not shown) advances the base plate 11 of the apparatus, and includes left and right positioning tools 4a and 4b and front and rear positioning tools 9c and 9d. It is inserted into the space 17 surrounded by the front and rear U-shaped plates 3, 7 and placed on the base plate 11.
In this state, the left and right positioning tools 4a and 4b are moved forward, and the electrode plate group G is positioned in the thickness direction with a slight gap between both end plates of the electrode plate group G. The positioning tools 9c and 9d are moved forward to lightly contact the separators S on both sides of the electrode plate group G, or the electrode plates are positioned in the front-rear direction with a slight gap therebetween to complete the electrode plate group positioning operation.
[0014]
Next, the piston rods of the left and right work holders 18a and 18b are advanced, and the positioned electrode plate group G is clamped by the pressure plates 19a and 19b at the tips thereof. Thereafter, the base plate 11 is retracted. Before or after the base plate 11 is retracted, the piston rods of the left and right guide holders 21a and 21b are advanced, and the left and right guide pieces 20a and 20b are moved away from the electrode plate group G. As described above, the battery case B placed on the battery case mounting table of the lifting device just below the electrode plate group G is raised as shown in FIG. In the process, the guide pieces 20a and 20b are arranged at positions corresponding to the lower surfaces of the left and right guide pieces 20a and 20b above the upper ends of the battery case side walls facing in the thickness direction. In this case, if desired, both end surfaces of the lower end portion of the electrode plate group G are pressurized by the guide piece mounting plates 22a and 22b of the left and right guide holders 21a and 21b via the adjacent guide pieces 20a and 20b. The lower end of the group G may be in a compressed state.
As described above, after the electrode plate group G is held between at least the left and right work holders 18a and 18b, the base plate 11 is retracted into the rear chamber 13 of the machine housing 2 as indicated by the phantom line in FIG.
[0015]
On the other hand, the battery case lifting device 29 is normally positioned at the front portion of the housing base 2a when not in use, and presses and accommodates the electrode plate group on the battery case mounting table 34 when in use. A suitable battery case G is placed and accommodated in the battery case clamp device 35, and is clamped from the front, rear, left and right by the respective clamp plates 35a, 35b, 35c, 35d, and then the battery case G is installed immovably. The mechanism 40 is driven to retract the battery case elevating device 29 so as to be positioned on the vertical axis C at the center thereof, as shown in FIGS. 4 and 5, just below the electrode plate group G positioned above.
[0016]
Next, the servo motor 30 is rotated forward, the rotary ball screw rod 32 is rotated forward via the endless belt 31, and is raised together with the four lifting rods 33a, 33b, 33c, 33d. The mounting table 34 that supports the upper and lower guide pieces 20a and 20b is raised so that the suspended portions of the left and right guide pieces 20a and 20b face the opposite walls b and b of the battery case B so as to intervene between the lower end of the electrode plate group G. When the battery case B is continuously raised in this state, the lower end of the electrode plate group G is first guided by the left and right guide pieces 20a and 20b and inserted into the battery case B, and then the opposite wall b of the battery case B , B are brought into contact with the lower surfaces of the left and right guide piece mounting plates 22a, 22b. Next, when the pressing of the guide holders 21a and 21b is released by releasing the pressing of the cylinder portion, and the battery case B is further raised in this state, the left and right guide holders 21a and 21b are also raised. When the left and right guide holders 21a and 21b are brought into contact with the left and right work holders 18a and 18b above them, the rise of the battery case B is stopped. That is, when the distance H of the predetermined height space increases, the rise of the battery case B is stopped. In the ascending process of the battery case B, the lower end portion of the electrode plate group G is smoothly inserted into the battery case B while being guided while the both end surfaces thereof are in sliding contact with the inner surfaces of the left and right guide pieces 20a and 20b. In this case, since the portion of the electrode plate group G inserted into the battery case B is an extremely short height H corresponding to the height space H, the electrode plate group G is moved from the lower end of the electrode plate group G. Since the left and right guide holders 21a and 21b are short enough to contact the left and right work holders 18a and 18b, the battery case can be smoothly and reliably removed without buckling of both end plates of the electrode plate group G. Can be inserted into. In this case, when the lower end portion of the electrode plate group G is previously pressed by the left and right guide holders 21a and 21b and the thickness thereof is compressed, both end surfaces of the electrode plate group G and the guide pieces 20a and 20b Therefore, the lower end of the electrode plate group G can be more easily inserted. Therefore, in this case, after the lower end of the electrode plate group G is inserted into the battery case B, the piston rods of the left and right guide holders 21a and 21b are retracted at least slightly to release the compression, and the subsequent rise of the battery case B is continued. As the guide holders 21a and 21b that are lifted as they come into contact with the left and right work holders 18a and 18b, the battery case B is stopped from rising. Thus, the insertion of the lower end portion of the electrode plate group G corresponding to the height space H is completed. (See FIGS. 6 and 7).
[0017]
Next, after the piston rods of the left and right work holders 18a and 18b holding the electrode plate group G are retracted to release the holding, the front and rear positioning tools 9c and 9d are arranged on both sides of the electrode plate group G. If it is in contact with the separator, the battery case B is lowered after that, or after retracting to a non-contact state. The left and right guide pieces 20a and 20b have a hanging part as shown in FIG. 6 such that the left and right opposing side walls b and b of the battery case B and the lower end part of the electrode plate group G compressed and inserted into the battery case B. Therefore, the electrode plate group G and the left and right guide pieces 20a and 20b are also lowered when the battery case B is lowered. Accordingly, at the same time, the left and right guide pieces 20a and 20b are also lowered. The left and right guide holders 21a and 21b holding the lowering are also lowered. Thus, the left and right guide holders 21a and 21b are lowered to the original lowered position where they are in contact with the lower stoppers 25a and 25b and stopped. That is, the height space H is lowered. When the battery case B is lowered by a distance corresponding to the height space H, the descent is stopped. The electrode plate group G is lowered by the height corresponding to the height space H by the battery case lowering step of lowering the battery case B by the amount corresponding to the height space H. (See FIG. 8).
[0018]
Next, the left and right work holders 18a and 18b are moved forward again to sandwich the electrode plate group, and then the battery case B is raised again. As the battery case B rises, the left and right guide pieces 20a and 20b The guide holders 21a and 21b are also pushed up and raised, and when the left and right guide holders 21a and 21b come into contact with the upper left and right work holders 18a and 18b, the rise of the battery case B is stopped. By this step of raising the battery case b, the battery case raising step of inserting the electrode plate group G into the battery case B by the height H corresponding to the same predetermined height space H as described above, After unfastening the electrode plate group G by the work holders 18a and 18b, the battery case B is lowered again by an amount corresponding to the height space H, and the electrode plate group G Next, the battery case lowering step of drawing out downward by the height to be inserted, that is, the height corresponding to the height space H is repeated. For example, when the electrode plate group G having a height dimension of 355 mm is inserted into the battery case B, the stroke of the guide holders 21a and 21b moving up and down, that is, when the height space H is 70 mm, the battery case is raised. Thus, the height of the electrode plate group inserted into the battery case is 70 mm, and as the height of the electrode plate group to be inserted is lowered by 70 mm as the battery cell descends, the battery cell ascent and descent process is performed in 4 steps. It will be inserted into a 280 mm battery case by repeating the operation. Thus, according to the present invention, the left and right guides have a short distance H that does not cause buckling of the electrode plate group G in the ascending and descending steps of the battery case, and in the illustrated example, a short height distance H of only 70 mm. Since the insertion into the battery case B is repeated via the pieces 20a and 20b, the both ends of the electrode plate group G can be inserted smoothly and satisfactorily without buckling. After repeated such insertion, the height is slightly 7 Since the upper end of the 5 mm electrode plate group will remain uninserted above the battery case B (see FIG. 9), the electrode plate group press is required to completely accommodate the electrode plate group G in the battery case B. The following is performed by the lowering device.
[0019]
That is, as the final step of the insertion operation, the electrode plate group is pressed from above by the electrode plate group pressing device provided separately from the device or integrally with the device, as described below. The electrode plate group G is completely accommodated to complete the assembly of the storage battery.

A cylinder portion is attached to the upper surface of the piston rod 45a1 and 45b1, and the piston rods 45a1 and 45b1 pass through the through-holes 43a and 43b and project downwardly into the space below the attachment plates 44a and 44b. Piston cylinders 45a and 45b, connecting members 46a and 46b attached to the tip of each piston rod, and the connecting members 46a and 46b in the front wall of the positioning tools 4a and 4b. Pressing member 47a which is connected through an opening extending in the vertical direction provided on the parts, consisting of 47b. In the illustrated example, the pressing members 47a and 47b have a length in the width direction sufficient to straddle the positive and negative straps PS and NS disposed on the upper surface of the electrode plate group G, and these straps PS, It is formed on plate-like pressing members 47a and 47b that respectively press the PN from above. In the drawings, 48a and 48b indicate MS guides. Thus, as described above, in the insertion operation of repeatedly raising and lowering the battery case B, most of the electrode plate group G is inserted into the battery case B. As shown in FIG. When the positioning tool 4a, 4b is positioned below, the left and right positioning tools 4a, 4b are advanced as the final stage of the insertion work, and the plate-like pressing members of the left and right electrode plate group pressing devices 42a, 42b are moved forward. After stopping 47a and 47b above the positive and negative straps PS and NS of the electrode plate group G and at positions orthogonal thereto, the left and right piston rods 45a1 and 45a1 are moved downward to move the positive and negative straps PS, NS is pressed from above, and the entire electrode plate group G is completely inserted into the battery case B, thereby completing the operation of inserting the electrode plate group G into the battery case B, and thus the electrode plate in the battery case. A lead-acid battery in which the group is compressed and stored is obtained. In the drawings, PP represents a positive electrode column, and PN represents a negative electrode column.
[0020]
In some cases, when the electrode plate group is inserted and accommodated in the battery case, the electrode plate group G is formed by laminating one or several spacers on both end faces of the electrode plate group so as to obtain a desired compression force. Need to be inserted into the tank. In order to be able to perform an insertion operation in such a case, the above-described electrode plate group insertion device 1 includes spacers on the front surfaces of the right and left positioning tools 4a and 4b as shown in FIGS.

The front and rear positioning tools 4c and 4d are moved forward and left and right with a slight gap between the spacer guides 49a and 49b arranged on the front surface and both end faces of the electrode plate group G. After advancing to a position where it touches or does not touch both side surfaces of the group G and positioning in the front-rear direction, the inner dimensions of the battery case side walls facing each other in the thickness direction of the electrode plate group of the battery case are taken into consideration, and When the board group is inserted, it can be accommodated with a predetermined compression force. A desired number of spacers (not shown) suitable for the above are inserted into the spacer insertion space S in the left and right spacer guides 49a and 49b from above, and are guided thereby to align with both end faces of the lower end plate group G. In the state Be Place on the plate 11. Next, the electrode plates G are clamped in a state where the piston rods of the left and right work holders 18a and 18b are advanced to overlap the left and right spacers on both end faces of the electrode plate group G.
