Abstract
Description
なお往復運動の1往復運動の距離は、極板保持装置に保持された状態で上方向に位置する充填極板の枠骨の一辺の長さの2倍以上の距離であるのが好ましい。このようにすれば極板面全面に螺旋状の空気流を吹き付けることができるので、螺旋状の空気流が当たらない部分が残ることを確実に防止することができる。
[第1の実施の形態]
図3(A)には、本発明の鉛蓄電池用のペースト式極板の製造方法及び該方法に用いる極板クリーニング装置の第1の実施の形態の要部が概略的に示されており、図3(B)にエアーノズル6と充填極板10との関係を示してある。図3(A)に示すように、本実施の形態では、一対のベルトコンベア9,9に一対の耳部5,5が懸架され充填極板10が所定の間隔をあけて垂下した状態で運搬されている。なお図示していないが、ベルトコンベア9,9には、それぞれ一対の耳部5,5が嵌合される凹部を備えた複数の嵌合部がベルトの移動方向に所定の間隔を開けて配置されている。この嵌合部の存在により、充填極板10の位置決めが図られている。そして本実施の形態では、一対のベルトコンベア9,9によって、複数枚の充填極板10を極板面が上下方向に延びる姿勢で且つ隣り合う二枚の充填極板10,10の間に間隔を開けて保持する極板保持装置が構成されている。なお本実施の形態では、充填極板10は900g以上の重量を有しており、螺旋状の空気流8が吹き付けられても、大きく煽られることはない。
図5(A)乃至(C)には、本発明の鉛蓄電池用のペースト式極板の製造方法及び該方法に用いる極板クリーニング装置の第2の実施の形態の要部が概略的に示されている。
また本実施の形態でも、エアーノズル6A乃至6Dから、短い間隔で噴射されるパルスエアーを吹き出すようにしてもよい。
[第3の実施の形態]
図6には、本発明の鉛蓄電池用のペースト式極板の製造方法及び該方法に用いる極板クリーニング装置の第3の実施の形態の要部が概略的に示されている。本実施の形態では、螺旋状空気流発生装置が、1以上のエアーノズル(図6では1つ)からなる複数(図6では3つ)のエアーノズル群を備えている。具体的には、一対のフレーム13A,13Aに支持された電動スライダ12Aには、図示しないグリッパを介してエアーノズル61が実装されており、一対のフレーム13B,13Bに支持された電動スライダ12Bには、図示しないグリッパを介してエアーノズル62が実装されており、一対のフレーム13C,13Cに支持された電動スライダ12Cには、図示しないグリッパを介してエアーノズル63が実装されている。3つのエアーノズル群またはフレーム13A乃至13Cは、複数枚の充填極板が並ぶ方向と直交する方向に、隣り合う二枚の充填極板10間の間隔に実質的に等しい間隔をあけて配置されている。そして螺旋状空気流発生装置の電動スライダ12A乃至12Cは、3つのエアーノズル61乃至63を、それぞれ複数枚の充填極板10が並ぶ方向と直交する方向に往復動作させる。このようにすると、隣り合う二枚の充填極板の二組以上に同時に螺旋状の空気にさらすことができる。本実施の形態では、図7(A)及び(B)に示すように、三組の隣り合う二枚の充填極板に対して3つのエアーノズル61乃至63を対応させて、乾燥を行うことができる。図7(A)に示す状態から図7(B)に示す状態に、充填極板が搬送されると、一組の隣り合う二枚の充填極板の間の間隙には、3つのエアーノズル61乃至63が1回ずつ対応して配置されることになる。
[ブラシかけ]
次に、格子基板1にペースト状活物質を充填した後プレスしたときに、枠骨2に活物質がはみ出して枠骨2の厚み方向端面に付着することがある。この付着した活物質が、鉛蓄電池使用中の振動、活物質の劣化等により剥がれ落ちて短絡が発生することがある。そのため、充填極板10の初期乾燥後、または、螺旋状の空気流8を吹き付けた後に、枠骨2の厚み方向端面に付着した活物質を取り除くのが好ましい。活物質を取り除く方法としては、一対のブラシを回転させ、ブラシ間に枠骨2を通し。枠骨2にブラシがけをすることにより容易に行うことができる。ブラシの材質は、ワイヤー、合成樹脂、動物性のものが考えられるが、強度、コスト面からワイヤーブラシを用いるのが好ましい。また、ブラシを用いずに、切削工具を用いて枠骨2上に付着した活物質を取り除いても良い。
[実施例]
以下、本発明の実施例について、詳細に説明する。
正負格子基板:縦:395mm×横:142mm×厚さ:6mm
負極格子基板:縦:395mm×横:142mm×厚さ:4mm
の鋳造格子基板を作製した。
上述した格子基板をベルトコンベアに寝かせた状態で移動させて、上述したペースト状活物質を収容したホッパを備えた充填機の下方を通過するときに、ペースト状活物質を充填し、成形ローラで加圧して充填極板を作製した。ペースト状活物質の充填量は、乾燥質量が、正極:1150g、負極:900gとなるように調整した。その後、作製した充填極板の両耳部をベルトコンベアに懸架して充填極板を垂下させた状態で運搬しながら温風を吹き付けて初期乾燥を行った。この後に、以下に説明する工程を実施した。
図3(A)に示すように、エアーノズル6を電動スライダ12に一個取り付け、これに対向する充填極板10の枠骨2とエアーノズル6のノズルガイド大径側開口との距離が20mmとなるように調整した。次に、隣り合う2枚の充填極板10,10の極板間隔を20mmにしてベルトコンベア9,9に懸架し垂下した状態にした。ベルトコンベア9,9を駆動せず、充填極板10を静止させた状態で、エアーノズル6から吐出される螺旋状の空気流が隣り合う2枚の充填極板10,10の極板間隙の中央部に導入されるように、エアーノズル6を充填極板10の両耳部5,5の間で枠骨2の長さ方向に沿って往復動作させた。
実施例1において、ベルトコンベア9,9を駆動し、充填極板10を移送しながら、エアーノズル6から吐出される螺旋状の空気流8を隣り合う2枚の充填極板10,10の極板間隙に導入し、エアーノズル6を充填極板10の両耳部5,5の間で枠骨2の長さ方向に沿って往復動作させた。
図4(A)乃至(C)に示すように、エアーノズル6A乃至6Dを電動スライダ12に取り付けたグリッパ14´に、フレーム13、13を挟んで片側に2個ずつ取り付け、片側2個の内、1個のエアーノズル6B、6Dをフレーム13方向へ10度傾けて配置し、充填極板10の端面とエアーノズルのノズルガイド大径側開口との距離が20mmとなるように調整した。そして、充填極板10を移送しながら、エアーノズル6A乃至6Dを往復動作させている。ここで、充填極板の運搬速度を調整して、例えば、充填極板10の位置が電動スライダ12の真下となったときにエアーノズル6A乃至6Dの移動動作と螺旋状の空気流8の吐出が開始され、エアーノズル6A乃至6Dが一往復したときに、次に移送された充填極板10の位置が電動スライダ12の真下に運搬されるようにした。
実施例1と同様にして作製した充填極板を初期乾燥した後、充填極板の極板間隙に螺旋状の空気流を導入せずに、枠骨の厚み方向端面に付着した活物質のみを、実施例1と同様にして取り除いた。
実施例、比較例で正極充填極板と負極充填極板を各1000枚ずつ作製し、余分な活物質を取り除くことができずに、極板面に付着したままとなった不具合充填極板の枚数を表1に示す。
実施例3、比較例で作製した正極充填極板と負極充填極板を、セパレータを介して交互に所定枚数積層し、同極同士をストラップ溶接した極板群を作製した。作製した極板群を電槽に挿入して蓋体を取り付け、極柱を封口し、希硫酸を所定量注入後、電槽化成を行って鉛蓄電池を作製した。尚、正負充填極板は、実施例3、比較例共に、余分な活物質を取り除いて使用した。
実施例3:10.26h
比較例 :10.18h
となり、大きな差はなかった。これにより、電池容量を維持して短絡の原因となる付着活物質を取り除いたペースト式極板を作製できることが判る。
