Description

【０００１】
【発明の属する技術分野】
本発明は帯電ロ−ラ、特にリサイクル品として再使用される帯電ロ−ラの表面に付着したトナ−及び紙粉等を清掃する帯電ロ−ラの清掃装置に関する。
【０００２】
【従来の技術】
従来帯電ロ−ラの表面に付着したトナ−及び紙粉等の清掃は、作業者が水に浸したウエスを用いて綺麗になるまで軽く擦することによって行っていて、極めて作業効率が悪いものとなっており、また作業者によってその清掃度合いにばらつきが生じて２次作業工程が必要になるという問題があり、また作業者又は機械がブラシを使用して、帯電ロ−ラの表面を擦することによって行うことがあるが、この場合にはブラシの毛の直径が太いと、帯電ロ−ラの表面に傷を与え、反対に細くすると帯電ロ−ラの表面に固着し、又は付着したトナ−・紙粉等を満足できるように除去することができないという問題がある。
【０００３】
また溶剤を用いて洗浄しようとする場合、帯電ロ−ラの表面の特性に影響を与えることなく、洗浄することのできる溶剤を入手するのが困難であるという問題があり、また帯電ロ−ラの清掃装置に帯電ロ−ラ又はブラシの回転機構を設けると、それらを駆動又は制御する手段を設けなくてはならなくて、設備コストがかかるという問題があり、また帯電ロ−ラを廃棄するには、重量が大きいため過大な処理コストがかかるというような各種の問題がある。
【０００４】
【発明が解決しようとする課題】
そこでこれらの問題を解消することができるものとして、特開平６−２８９７５５号公報に開示されたような画像形成装置の帯電ロ−ラ、転写ロ−ラ、定着ロ−ラ等のロ−ラを、ケトン系溶媒又はケトンとアルコ−ルの混合溶媒で洗浄する帯電ロ−ラ洗浄装置が提供されている。
ところでこのような溶媒を使用すると、帯電ロ−ラの表面層の成分を抽出してしまって、帯電電位に影響があるというような問題がある。
【０００５】
そこで本発明の目的は、前記のような従来の帯電ロ−ラの清掃装置のもつ問題を解消し、帯電ローラ全面に、清掃回転ブラシを接触させて清掃することで効率よく短時間で、複数本の帯電ローラを清掃することができ、また清掃品質のばらつきがなく帯電ロ−ラ上に付着・固着したトナ−及び紙粉を除去することができる帯電ローラの清掃装置を提供するにある。

【発明の実施の形態】
図面において、図１，２は請求項１〜４に記載された発明に属する第１実施形態を示し、図３，４は請求項５〜８に記載された発明に属する第２実施形態を示す。
【００１０】
第１実施形態を説明することとする。１は清掃装置本体を示していて清掃箱２を有し、この清掃箱２の前後壁４，５と、１対の側壁８とで清掃室９が構成され、清掃箱２には開閉蓋３が装着されているとともに、清掃箱２の前後壁４，５と、１対の側壁８とで清掃室９が構成され、この清掃室９内に、この実施形態では２個の回転ブラシ７が長手方向に配置され、その軸１０が図１に示すように、清掃箱２の前後壁４，５間に設立された１対の側壁８に回転可能に支持されている。
【００１１】
開閉蓋３の装着時に、この開閉蓋３の裏面に、図２に示すように、帯電ロ−ラ６を回転ブラシ７の表面に、圧接して回転させるように支持する帯電ロ−ラ６の支持部材１１が設けられており、この支持部材１１は、押さえパッド１２及び押さえリブ１３を有している
【００１２】
そして清掃箱２内には、図１に示すように、回転ブラシ７の駆動モータ１６の駆動プーリ１８と、回転ブラシ７の受動プーリ１９とが配置されていて、これらに駆動ベルト２０が懸張されている。そして清掃箱２の外に回転ブラシ７の駆動モータ１６の制御装置２４及びその操作盤２５が設けられていて、操作盤２５には回転オンスイッチ２１、回転オフスイッチ２２及び回転可変スイッチ２３が設けられている。
【００１３】
前記のような第１実施形態において、帯電ロ−ラ６の清掃を行う場合には、各請求項に記載された発明において、１例として請求項１に記載された発明を参照して説明することとすると、開閉蓋３を取り外して図１に示すように、清掃室９内に横架している各回転ブラシ７の上に、これと平行して１対の帯電ロ−ラ６を、図１，２に示すように載置する。そして開閉蓋３を被せると、その裏面に設けられている帯電ロ−ラ支持部材１１で帯電ロ−ラ６を回転ブラシ７に低圧力で接触させる。そして回転ブラシ７を回転すると、回転ブラシ７が帯電ロ−ラ６の表面を擦ってその表面に付着・固着しているトナ−及び紙粉等を清掃することとなる。
【００１４】
この場合回転ブラシ７の毛の直径が、請求項３に記載された発明のように、０．５ｍｍ〜０．０５ｍｍとなっているものを使用すると、従来例のように、ブラシの毛の直径が太すぎて帯電ロ−ラ６の表面に傷を与えたり、細すぎて帯電ロ−ラの表面に固着し、又は付着したトナ−・紙粉等を満足でるように除去することができないという問題を起こすことがない。
【００１５】
また請求項４に記載された発明のように、帯電ロ−ラ６を回転ブラシ７へ低圧力で接触させ、回転ブラシ７の回転によって帯電ロ−ラ６が連れ回りする発明にあっては、省エネ効果が大きいのに加えて、装置全体のコストを低減することができる。
【００１６】
つぎに図３，４に示す請求項５〜８に記載された発明に属する第２実施形態について説明する。この第２実施形態は、給水手段２６を取り付けた点で、第１実施形態と相違するだけである。そこでこの給水手段２６について説明する。２７は水供給タンク、２８は水供給パイプ、２９は水供給ポンプ、３０は水供給ポンプ２９の制御装置であって、オン・オフスイッチ３０が設けられている。
【００１７】
前記のような第２実施形態で帯電ローラ６の清掃を行なう場合には、制御装置３１を操作して、給水手段２６の水供給ポンプ２９が作動すると、水供給パイプ２８を介して、清掃箱２内に鎖線で示す水位まで給水し、この水に回転ブラシ７の一部を浸して第１実施形態におけると同様にして、回転ブラシ７によって帯電ローラ６の表面を擦ってその表面に付着しているトナー及び紙粉等を清掃する。
【００１８】
このようにして、第２実施形態においては、水を使用することによって、消耗品費を抑制すると同時に、回転ブラシ７と帯電ローラ６との摩擦を緩和し、また回転ブラシ７の回転によって、随時水を供給しながら清掃していることにより、帯電ローラ６の表面に付着したトナー及び紙粉の汚れを効率よく除去することができる。
【００１９】
