Description

【０００１】
【従来の技術】
従来、この種回転ベルト除菌洗浄器としては、本発明者の発明に係る特許第３００４５８８号がある。すなわち、図９および図１０に示されるように、筐体１内に、被消毒回転ベルト４に弾性機構の弾性により圧接し、かつ筐体１内の消毒液ａ内を通過する消毒回転ベルト５と、この消毒回転ベルト５に湿潤された消毒液量を適宜量に調整する絞り機構が設置された回転ベルト消毒器において、前記弾性機構が、それぞれ一端がリンク機構の固定リンク６に枢着された上下１対の可動リンク９、１０遊端側軸受け部１５、１６に、消毒回転ベルト５のドラム１１、１２の回転軸１３、１４が枢支され、かつ上方の可動リンク９の枢着軸７と下方の可動リンク１０の遊端側との間に引張りスプリング１８が取り外し自在に張設されたことを特徴とする回転ベルト消毒器がある。
【０００２】
【発明が解決しようとする課題】
しかしながら、上記回転ベルト消毒器では、被消毒回転ベルト４は消毒回転ベルト５と常時圧接しており、しかも消毒回転ベルト５の一部は常に消毒液ａ中に浸漬されているため消毒液ａが無くなるまで消毒回転ベルト４を湿潤状態とすることになる。したがって、たとえば無端環状の被消毒回転ベルト４が１回転して消毒の必要がなくなっても消毒液が残っている限り消毒が続行され、あらかじめ消毒液の必要量を算出して消毒液を筐体内に貯溜していても、消毒液の無駄が生じることが多かった。また、消毒液が消費されて次回の消毒液を補給するには時間を見計らって人為的に補給せねばならず、管理が面倒であるとともに、被消毒回転ベルト４に消毒回転ベルト５が常時圧接しているため、消毒回転ベルト５の歪形や摩耗が著しく、長期間の使用に際してはその取り替えや取り替えのための人件費などの維持費が高額となるばかりでなく、消毒回転ベルト５が被消毒回転ベルト４の走行停止時にも圧接されているため、被消毒回転ベルト４の走行が再開された場合、該ベルト４の表面に消毒回転ベルト５との接触染みや消毒液の固化染みがつき、汚染感を抱かせるので、これを人為的に除去せねばならない労力を必要とするという問題もあった。
【０００３】
本発明は、このような問題点を解決するために、被除菌洗浄回転ベルトと除菌洗浄液塗布ローラとの接触を、回転ベルトが停止した時は離反させ走行時には接触させることにより、被除菌洗浄回転ベルトに除菌洗浄液塗布ローラとの接触染みや除菌洗浄液の固化染みを付着させることなく、回転ベルトと除菌洗浄液塗布ローラの歪形や摩耗を可及的に防止し、かつ除菌洗浄液は被除菌洗浄回転ベルトに対する必要量だけを供給して除菌洗浄液の無駄な消費をなくすとともに、装置自体にタイマー機能を持たせ、除菌洗浄液の定期的自動補給を可能として装置の維持管理費等の節減を図ることを目的としている。
【０００４】
【課題を解決するための手段】
この目的を達成するため、本発明は、筐体内に、被除菌洗浄回転ベルトの走行と同期して回転させられる駆動ローラと、この駆動ローラの回転により前記被除菌洗浄回転ベルトに除菌洗浄液を塗布する除菌洗浄液塗布ローラを被除菌洗浄回転ベルトに接触させ、駆動ローラの回転停止により前記除菌洗浄液塗布ローラを被除菌洗浄回転ベルトから離反させる除菌洗浄液塗布ローラ接離装置と、前記除菌洗浄液塗布ローラに除菌洗浄液を供給する除菌洗浄液供給トレーと、前記駆動ローラの所定の回転数毎に除菌洗浄液貯留タンクから除菌洗浄液供給トレーに除菌洗浄液が供給される除菌洗浄液供給装置と、を備えたことを特徴としている。ここで、上記駆動ローラは左右１対の駆動ローラからなり常時回転ベルトと接触していることが好ましい。このようにすることにより、この駆動ローラの回転や停止、あるいはその回転数を利用して各機構の作動の自動制御を行うことができるようになる。
【０００５】
また、前記除菌洗浄液塗布ローラ接離装置は、一方の駆動ローラの回転・停止と連動して回転・停止する減速回転軸に設けられたギヤと、このギアと噛合離脱する偏心ギアと、この偏心ギアの回転・停止と連動して前記除菌洗浄液塗布ローラを昇降させる除菌洗浄液塗布ローラ昇降軸と、他方の駆動ローラの回転・停止と連動して回転・停止するフライホィールと、このフライホィールの回転・停止と連動して、前記除菌洗浄液塗布ローラを上昇させた際の前記除菌洗浄液塗布ローラ昇降軸に係脱する昇降軸係脱手段と、を備えていることが好ましい。このような除菌洗浄液塗布ローラ接離手段を設けることにより、除菌洗浄液塗布ローラと被除菌洗浄回転ベルトの接離が、被除菌洗浄回転ベルトの走行と停止に連動して行わせることができて被除菌洗浄回転ベルトや除菌洗浄液塗布ローラ等の歪形や摩耗、あるいは被除菌洗浄回転ベルトに除菌洗浄液による染みの発生を可及的に防止できるようになる。
【０００６】
そして、ここで用いられる昇降軸係脱手段は、前記フライホィールの回転による遠心力により円周方向に移動する重錘と、前記フライホィールの回転軸の軸心に軸動自在に設けられ作動ピンと、前記重錘の円周方向の移動により前記作動ピンをその軸方向に軸動させる軸動変換機構と、その作動ピンの軸動を上下動に変換する上下動変換機構と、この上下動変換機構の下方への押圧時に除菌洗浄液塗布ローラ昇降軸との係止準備が完了し、押圧解除時に除菌洗浄液塗布ローラ昇降軸から離脱する係脱爪と、を備えていることが好ましい。このような昇降軸係脱手段を用いることにより、除菌洗浄液塗布ローラと被除菌洗浄回転ベルトの接離が自動的に行われ、除菌洗浄液の有効利用と回転ベルト除菌洗浄器の保守管理が容易となる。
【０００７】
さらに、前記軸動変換機構は、重錘の円周方向の移動によりフライホィールの軸方向に揺動されてその端部が前記作動軸の端部を押圧する揺動杆と、前記作動軸を常時前記係脱爪の押圧解除側に付勢する付勢手段と、を備えても良い。このような機構を用いることにより、駆動ローラの回転を簡易かつ確実に直進運動に変えることができる。また、前記除菌洗浄液供給装置は、前記減速回転軸に設けられたウォーム、およびこのウォームと噛合させた平カムを備えたウォームホィールからなる減速機構と、この減速機構の平カムに当接されたガイドピンにより作動される除菌洗浄液供給ポンプと、この除菌洗浄液供給ポンプと連接された除菌洗浄液貯留タンクと、を備えてもよい。このような除菌洗浄液供給装置を用いると、減速器の減速比を考慮することにより除菌洗浄液貯留タンクからの必要量の除菌洗浄液を、定期的かつ自動的に除菌洗浄液供給トレーに供給することができて、除菌洗浄液のロスを可及的に少なくすることができる。
【０００８】
前記除菌洗浄液塗布ローラを、除菌洗浄液供給トレー内の除菌洗浄液にその一部が浸漬されて自由に回転する除菌洗浄液供給ローラに接触させ、その除菌洗浄液供給ローラに絞りローラを配設したり、除菌洗浄液供給ポンプのインレットとアウトレットに除菌洗浄液の流れ方向への一方向弁を設けることが好ましい。このような構成とすることにより、除菌洗浄液塗布ローラの耐久性を向上させ、湿潤度を平均に保ち、除菌洗浄液の逆流を防止し、除菌洗浄液供給ポンプの交換時に除菌洗浄液供給パイプや筐体内に残留する除菌洗浄液を外部に遺漏するおそれもなくなる。さらに、除菌洗浄液貯留タンクと筐体との着脱口に接続時には開、取り外し時には閉となる一方向弁を設けておけば、除菌洗浄液貯留タンクへの除菌洗浄液補給時に、筐体からの脱着が容易で作業性に富み、好適である。
【０００９】
【発明の実施の形態】
以下図面に基づいて本発明に係る回転ベルト除菌洗浄器の実施例を説明する。
図１は本発明に係る回転ベルト除菌洗浄器の全体の概略説明図、図２はフライホィール部分の一部を切欠して示す斜視図、図３は筐体を除く全体の右前方向からの斜視図、図４は除菌洗浄液供給装置の詳細説明図、図５は除菌洗浄液塗布ローラ接離装置の一部拡大説明図、図６は筐体を除く全体の左前方向からの斜視図、図７は筐体を除く全体の平面図、図８はウォームホィールとピストン駆動アームと除菌洗浄液供給ポンプとの関連説明図である。
【００１０】
図１において、２１、２２は筐体２３内のフレームＢに揺動自在で回転自在に取り付けられ、かつ被除菌洗浄回転ベルトＡと圧接する左右１対の駆動ローラで、一方の駆動ローラ２１には、フレームＢに揺動自在で回動自在に取り付けられた回転軸２４に固定されたＶプーリ２５、Ｖベルト２６、フレームＢに回動自在に取り付けられた回転軸２８に固定された加速Ｖプーリ２７を介して該回転軸２８に固定されたフライホィール２９が連設されている。フライホィール２９の中心を含む放射方向の両側には、図２に示されるように、一端部がフライホィール２９に枢着軸３２により枢支され、他端部の遊端に重錘３０が取り付けられて、フライホィール２９の回転時にその遠心力により重錘３０がフライホィール２９の円周方向に移動するのをガイドするガイド片３１がそれぞれ設けられている。
【００１１】
ガイド片３１の内側中央部には、フライホィール２９の回転により、重錘３０がその遠心力で枢着軸３２を軸としてフライホィール２９の円周方向に移動したとき、フライホィール２９の回転軸２８の中心に回転が阻止されかつ軸動自在に設けられた作動ピン３３のフランジ３５を押圧して作動ピン３３をフレームＢの内側に軸動させる逆Ｌ字状の作動爪３４が連設されている。この作動爪３４は、逆Ｌ字状の偶角部が１対のブラケット３６、３６により枢支され、その下端がガイド片３１に形成された嵌入孔３１ａに嵌入されるとともに、上端が作動ピン３３に形成されたフランジ３５に接離自在に配設されている。
このフランジ３５とフライホィール２９との間には、フライホィール２９の回転停止により重錘３０に対する遠心力が失われ、重錘３０がフライホィール２９の中心方向にその自重で移動可能となったとき、作動ピン３３を元位置に復帰させるためのばね３７が介装されている。図中２９ａは、フライホィール２９に設けられた重錘３０のガイド片３１の移動範囲規制用のストッパである。
【００１２】
フレームＢの内側の作動ピン３３の先端は、作動ピン３３の軸動を上下動に変換する伝動片３８と揺動杆３９に連設されている。
すなわち、作動ピン３３の先端は、中央部がフレームＢに枢着された逆Ｌ字状の伝動片３８の下端部に形成された作動ピン衝合部３８ａに当接され、伝動片３８の上端は、中央部がフレームＢに枢着された揺動杆３９の一端部下側に当接され、揺動杆３９の他端部は後述の除菌洗浄液塗布ローラ昇降軸４２と係脱自在な係脱爪作動片４０に衝合させている。
係脱爪作動片４０は、下端に係脱爪４０ａを有し、上端部の軸４１を中心として下方が前後に揺動するようにフレームＢの前面板に取りつけられ、揺動杆３９との衝合部４０ｂが揺動杆３９により押圧されると、その下端部がフレームＢの内側に揺動して係脱爪４０ａが除菌洗浄液塗布ローラ昇降軸４２に傾斜して係止するように準備される。除菌洗浄液塗布ローラ昇降軸４２が上昇してくると、該昇降軸４２は係脱爪４２ａに係止され、揺動杆３９による押圧が解除されると、後述する可動フレームＣ、およびこれに取り付けられた除菌洗浄液塗布ローラ昇降軸４２等の自重と、係脱爪作動片４０が軸４１を軸としてその下方が自重により旧位置へ復帰する復帰力とにより、係脱爪４０ａが除菌洗浄液塗布ローラ昇降軸４２から離脱するように接離自在に配設されている。
ここで用いられる係脱爪４０ａとしては略三角形の爪を後方に張出させた状態とし、除菌洗浄液塗布ローラ昇降軸４２が上昇してきて係脱爪４２ａに係止されるときは、該昇降軸４２が係脱爪４２ａの下面に沿って上昇し、係脱爪４２ａの上方に到ると係脱爪作動片４０が後方へ揺動して該昇降軸４２を係止するようにしたものが用いられる。
【００１３】
また、他方の駆動ローラ２２には、後述の駆動ローラアーム７８に枢着された回転軸４３に固着されたＶプーリ４４、Ｖベルト４５、フレームＢに回動自在に取り付けられた減速Ｖプーリ４６を介して回動される回転軸４７に、減速ギア群４８乃至５３を介在させて減速回転軸５４を減速回転させる。
減速ギア群中、ギア４８は回転軸４７に固定され、これと噛合わされた大径のギア４９と小径のギア５０は減速回転軸５４に対して自由回転状に取り付けられ、小径のギア５０と噛合わされた大径のギア５１と小径のギア５２は回転軸４７に自由回転状に取り付けられ、この小径のギア５２と噛合わされた大径のギア５３は減速回転軸５４に固定されて減速ギア群が構成されている。
減速回転軸５４には左右１対の筒型ギヤ５５、５５が取り付けられており、両筒型ギヤ５５、５５間にはウォームギア５６が取り付けられている。そして両筒型ギア５５、５５には、前記除菌洗浄液塗布ローラ昇降軸４２に回動自在に取り付けられた１対の偏心ギア５７、５７が接離自在に噛合わされる。
除菌洗浄液塗布ローラ昇降軸４２と偏心ギア５７、５７間には、除菌洗浄液塗布ローラ昇降軸４２が下降して偏心ギア５７、５７の短径側が筒型ギア５５、５５と噛合った後、筒型ギア５５、５５の回転により偏心ギア５７、５７の長径側から短径側に回転した際、偏心ギア５７、５７の長径側を上方へ跳ね上げるためのスプリング５８、５８が設けられている。
【００１４】
除菌洗浄液塗布ローラ昇降軸４２は、図４に示されるように、左右１対の可動フレームＣ、Ｃの先端部に回動自在に支持されており、この可動フレームＣ、Ｃはその後端部がフレームＢに軸５９、５９により枢着されて、先端部、すなわち除菌洗浄液塗布ローラ昇降軸４２の取り付け側が遊端となるようにフレームＢに揺動自在に取り付けられている。除菌洗浄液塗布ローラ昇降軸４２の背面の可動フレームＣ、Ｃ間には、下側に除菌洗浄液供給トレー６０が図示されていないスプリングにより昇降自在に弾持され、その上側には被除菌洗浄回転ベルトＡと接離する除菌洗浄液塗布ローラ６１が回転自在に取り付けられている。除菌洗浄液供給トレー６０内には、除菌洗浄液ａ内に浸漬された自由回転する除菌洗浄液供給ローラ６２が配設され、この除菌洗浄液供給ローラ６２と除菌洗浄液塗布ローラ６１とに接する位置で、左右の可動フレームＣ、Ｃ間には、除菌洗浄液塗布ローラ６１への除菌洗浄液ａの付着量を調整するための絞りローラ６３が回動自在に介在されている。
【００１５】
これら除菌洗浄液供給トレー６０、除菌洗浄液塗布ローラ６１、除菌洗浄液供給ローラ６２、および絞りローラ６３は、一体として可動フレームＣ、Ｃに対して昇降可能に両フレームＣ、Ｃ間にスプリング（図示せず）により弾持させ、被除菌洗浄回転ベルトＡの走行中、該ベルトＡと除菌洗浄液塗布ローラ６１との接触振動が吸収されるように構成されている。図中、６０ａは除菌洗浄液供給トレー６０の両側に突設されたガイドピン、８２はフレームＢに穿設された昇降幅規制孔である。
【００１６】
上記除菌洗浄液供給トレー６０は、シリンダ６４ａとピストン６４ｂからなる除菌洗浄液供給ポンプ６４を介して除菌洗浄液貯留タンク６５と可撓性パイプ６６、６７により連結されており、除菌洗浄液供給ポンプ６４のインレット６８にはポンプ内が陰圧の時に開、陽圧のときに閉となる一方向弁（図示せず）が、アウトレット６９にはポンプ内が陽圧の時に開、陰圧のときに閉となる一方向弁（図示せず）が取り付けられるとともに、除菌洗浄液貯留タンク６５の除菌洗浄液供給口７０と、この除菌洗浄液供給口７０が着脱されるフレームＢに取り付けられたタンク着脱口７１には、両者が結合されたときに開となり、分離されたときに閉となる開閉弁（図示せず）がそれぞれ設けられている。
【００１７】
前記減速回転軸５４に取り付けられているウォームギア５６には、図８に示されるように、内面に平カム７３を備えたウォームホィール７２が噛合わされており、この平カム７３には除菌洗浄液供給ポンプ６４のピストン６４ａを作動させるピストン駆動アーム７４のガイドピン７５が配設されている。ピストン駆動アーム７４の後端は、フレームＢの前面板に軸７６により枢着されて先端部が昇降自在に取り付けられ、その先端が除菌洗浄液供給ポンプ６４のピストン６４ｂの上端部に連設されるとともに、中央部分に上記ウォームホィール７２の平カム７３と当接されるガイドピン７５が固定されている。ピストン駆動アーム７４には、その先端部が常時下側に弾性が付勢されるようにスプリング７７が張設されており、平カム７３とガイドピン７５とこのスプリング７７によりピストン駆動アーム７４の先端部を昇降させるように構成されている。
【００１８】
また、前記駆動ローラ２１、２２とＶプーリ２５、４４は、図６および図７に示されるように、駆動ローラ２１、２２を被除菌洗浄回転ベルトＡと圧接させるため、および被除菌洗浄回転ベルトＡの走行中、該ベルトＡと駆動ローラ２１、２２との接触振動を吸収させるための弾性機構を介してフレームＢに取り付けられている。すなわち、駆動ローラ２１、２２とＶプーリ２５、４４は、一端がフレームＢに枢着され、他端が揺動自在な遊端に形成された駆動ローラアーム７８の該遊端側に枢着され、駆動ローラアーム７８の遊端部には、駆動ローラアーム７８の揺動幅を規制する揺動幅規制孔８０が穿設されるとともに、この揺動幅規制孔８０にはフレームＢに固定されたピン８１が嵌入されており、かつ駆動ローラアーム７８の遊端には駆動ローラアーム７８を揺動幅規制孔８０上方へその弾性で引き上げるスプリング７９が張設されている。
【００１９】
つぎに本実施例に係る回転ベルト除菌洗浄器を、エスカレータの回転ベルトの繰り込み側に使用した場合をの使用例をその作用とともに説明する。
上記のように構成され、筐体２３内に組み立てられた回転ベルト除菌洗浄器を、図９に示される従来例におけると同様に、エスカレータにおける無端環状の回転ベルトの繰り込み側に除菌洗浄液塗布ローラ６１側を、除菌洗浄液貯留タンク６５側を手前に配して設置し、その駆動ローラ２１、２２を回転ベルトＡに圧接させる。エスカレータを作動させ、被除菌洗浄回転ベルトＡの走行を開始させると、除菌洗浄器の駆動ローラ２１、２２が被除菌洗浄回転ベルトＡとの摩擦力により回転する。駆動ローラ２１の回転は、回転軸２４、Ｖプーリ２５、Ｖベルト２６、加速Ｖプーリ２７、回転軸２８を介してフライホィール２９に伝えられ、フライホィール２９の回転によって、重錘３０が遠心力でフライホィール２９の外周側に移動する。この重錘３０の外周側への移動により、ガイド片３１、作動爪３４、フランジ３５を介して作動ピン３３がフレームＢの内側に軸動する。この軸動は伝動片３８、揺動杆３９を介して係脱爪作動片４０に伝えられ、その下端部の係脱爪４０ａを除菌洗浄液塗布ローラ昇降軸４２側へ揺動させる。
【００２０】
一方、駆動ローラ２２の回転は、回転軸４３、Ｖプーリ４４、Ｖベルト４５、減速Ｖプーリ４６、回転軸４７、減速ギア群４８〜５３を介して減速回転軸５４、筒型ギア５５、ウォームギア５６を減速回転させる。筒型ギア−５５には、除菌洗浄器の始動前には偏心ギア５７の短径側が噛合わされており、ウォームギア５６と噛合わされているウォームホィール７２の平カム７３の中心軸側には、ピストン駆動アーム７４のガイドピン７５が位置しているので、減速回転軸５４が回転を開始すると偏心ギア５７およびウォームホィール７２も定められた速度で回転を開始する。偏心ギア５７がその長径側まで回転させられると、除菌洗浄液塗布ローラ昇降軸４２はその上限まで上昇すると同時に、係脱爪作動片４０の係脱爪４０ａに係止される。除菌洗浄液塗布ローラ昇降軸４２が係脱爪４０ａに係止された後、偏心ギア５７と筒型ギア５５との回転がさらに進むと、偏心ギア５７は筒型ギア５５との噛み合わせが解かれるので、スプリング５８によりその長径側が上方へ跳ね上げられる。
【００２１】
除菌洗浄液塗布ローラ昇降軸４２が上昇させられると、図４に示されるように、軸５９を中心として可動フレームＣの遊端部も同時に上昇し、これに弾持されている除菌洗浄液供給トレー６０、除菌洗浄液塗布ローラ６１、除菌洗浄液供給ローラ６２、絞りローラ６３も一体的に上昇させられるとともに、除菌洗浄液塗布ローラ６１は被除菌洗浄回転ベルトＡに圧接する。除菌洗浄液塗布ローラ６１と被除菌洗浄回転ベルトＡとが圧接された後で、ウォームギア５６とウォームホィ−ル７２とのギア−比により定められた時間の経過後、すなわち、ウォームホィール７２の平カム７３にガイドされているピストン駆動アーム７４のガイドピン７５が平カム７３の最短径部から最長径部へ移動する間に、ピストン駆動アーム７４は除菌洗浄液供給ポンプ６４のピストン６４ｂを引き上げ、除菌洗浄液供給ポンプ６４内に除菌洗浄液ａを除菌洗浄液貯留タンク６５から吸引し、駆動アーム７４のガイドピン７５が平カム７３の軸の最長径部から最短径部に達すると、ガイドピン７５がスプリング７７の弾性により平カム７３の回転軸側に引張されることによりピストン駆動アーム７４が除菌洗浄液供給ポンプ６４のピストン６４ｂを下降させ、シリンダ６４ａ内に吸引された除菌洗浄液ａはアウトレット６９から可撓性パイプ６７を介して除菌洗浄液供給トレー６０に供給される。
【００２２】
除菌洗浄液供給トレー６０に供給された除菌洗浄液ａは、除菌洗浄液供給ローラ６２、絞りローラ６３によりその付着量が調整されて除菌洗浄液塗布ローラ６１に塗布された後、被除菌洗浄回転ベルトＡに塗布される。被除菌洗浄回転ベルトＡに対する除菌洗浄液ａの塗布間隔を、例えば２時間毎とするには、駆動ローラ２２の回転速度と回転数の組合せで２時間経過する間にウォームホィール７２が半回転するように、減速プーリ４６、減速ギヤ群４８〜５３、ウォームギア５６およびウォームホィール７２の減速比を調節する。このように調節すると、２時間ごとに所定量の除菌洗浄液ａが除菌洗浄液供給トレー６０に供給され、その除菌洗浄液ａが被除菌洗浄回転ベルトＡに塗布される。
除菌洗浄液貯留タンク６５内の除菌洗浄液ａが消費されて、除菌洗浄液ａを除菌洗浄液貯留タンク６５内に補充するには、除菌洗浄液貯留タンク６５をフレームＢから取り外し、そのキャップを開けて除菌洗浄液ａを補充する。このとき、除菌洗浄液貯留タンク６５の除菌洗浄液供給口７０にはタンク着脱口７１との接続が解除されると除菌洗浄液供給口７０を閉塞する開閉弁が設けられているので、除菌洗浄液貯留タンク６５から除菌洗浄液ａが漏れることはない。
【００２３】
エスカレータの運行が停止され、被除菌洗浄回転ベルトＡの走行が停止されると、駆動ローラ２１、２２もその回転を停止する。一方の駆動ローラ２１が回転停止すると、これに連設されたフライホィール２９も停止して重錘３０の遠心力は働かなくなるので、作動爪３４はフリーの状態となり、ばね３７の弾性により作動ピン３３はそのフランジ３５で作動爪３４を非作動状態とし、作動ピン３３をフレームＢの外側に軸動させる。作動ピン３３がフレームＢの外側に軸動すると、伝動片３８も揺動杆３９も係脱爪作動片４０への押圧が解除されるので、除菌洗浄液塗布ローラ昇降軸４２は、可動フレームＣおよび可動フレームＣに取り付けられている除菌洗浄供給トレー６０、除菌洗浄液塗布ローラ６１、除菌洗浄液供給ローラ６２、偏心ギア５７等の自重により、係脱爪作動片４０の係脱爪４０ａから外れ、軸５９を中心として可動フレームＣの遊端部分が下降し、偏心ギア５７の短辺側と筒型ギア５５が噛合わされる。可動フレームＣの遊端部分が下降すると除菌洗浄液塗布ローラ６１と被除菌洗浄回転ベルトＡとの接触は解除され、旧に復する。
【００２４】
以上は回転ベルト除菌洗浄器が完全に１サイクル作動した場合を示したが、作動の途中において被除菌洗浄回転ベルトＡの走行が停止された場合、たとえば減速回転軸５４の筒型ギア５５と除菌洗浄液塗布ローラ昇降軸４２の偏心ギア５７とが噛合わされていて、除菌洗浄液塗布ローラ昇降軸４２が上昇の途中でまだ係脱爪作動片４０の係脱爪４０ａと係合されていない状態で駆動ローラ２１、２２の回転が停止した場合、除菌洗浄液塗布ローラ昇降軸４２は上昇の途中の状態で停止する。このとき、駆動ローラ２１の停止によりフライホィール２９の作動ピン３３はスプリング３７の弾性で旧に復し、係脱爪作動片４０に対する揺動杆３９の押圧は解除されるので、可動フレームＣは下降しようとするが、筒型ギア５５と偏心ギア５７とが噛合わされているため、その下降は阻止される。被除菌洗浄回転ベルトＡの走行が再開されると、前記同様にして係脱爪作動片４０の係脱爪４０ａが除菌洗浄液塗布ローラ昇降軸４２側に揺動する一方、偏心ギア５７の回転も回転停止時の状態から再開されるので、回転停止前および回転再開後の筒型ギア５５と偏心ギア５７の回転数が所定の回転数となったとき、すなわち、所定の時間経過後に前記同様にして除菌洗浄液ａの供給が行われた後、旧に復する。なお、被除菌洗浄回転ベルトＡが逆回転するときも、上記各回転軸や回転体は上記とは逆の回転をするのみで、同様の作動をする。
【００２５】
本実施例では上記のように構成され作動するものが示されているが、上記構成に限定されるものではない。たとえば減速手段は可変プーリや可変減速ギア等の既に知られている減速手段を用いて除菌洗浄液の塗布間隔を適宜調節できるようにしたり、除菌洗浄液の供給量や供給頻度を除菌洗浄液供給ポンプの容量変更等により可変とすることなど、本発明の範囲で適宜変更や選択ができることは当然である。
【００２６】
【発明の効果】
本発明は上記構成よりなるので、被除菌洗浄回転ベルトと除菌洗浄液塗布ローラとの接触を、被除菌洗浄回転ベルトがその走行を停止した時は離反させ、走行時には接触させることにより、被除菌洗浄回転ベルトと除菌洗浄液塗布ローラの歪形や摩耗、あるいは被除菌洗浄回転ベルトの染みの付着等を可及的に防止し、かつ除菌洗浄液は被除菌洗浄回転ベルトに対する必要量だけを供給して除菌洗浄液の無駄な消費をなくすとともに、装置自体にタイマー機能を持たせ、除菌洗浄液の定期的自動補給を可能として装置の維持管理費等の節減を図ることができる。

[Prior art]
Conventionally, as this kind of rotating belt sanitizer, there is Japanese Patent No. 3004588 according to the inventor's invention. That is, as shown in FIG. 9 and FIG. 10, the disinfection rotating belt 5 that presses against the disinfection rotating belt 4 by the elasticity of the elastic mechanism and passes through the disinfecting liquid a in the casing 1 in the housing 1. In the rotating belt disinfector provided with a throttle mechanism for adjusting the amount of the disinfecting liquid wetted to the disinfecting rotating belt 5 to an appropriate amount, each of the elastic mechanisms is pivotally attached to the fixed link 6 of the link mechanism. The rotating shafts 13 and 14 of the drums 11 and 12 of the sterilizing rotating belt 5 are pivotally supported by the pair of upper and lower movable links 9 and 10 free end side bearing portions 15 and 16, and the pivoting shaft of the upper movable link 9 is pivoted. There is a rotating belt disinfector characterized in that a tension spring 18 is detachably stretched between 7 and the free end side of the lower movable link 10.

[Problems to be solved by the invention]
However, in the above rotating belt disinfector, the disinfecting rotating belt 4 is always in pressure contact with the disinfecting rotating belt 5, and a part of the disinfecting rotating belt 5 is always immersed in the disinfecting liquid a, so The sterilization rotating belt 4 is kept in a wet state until it disappears. Therefore, for example, even if the endless annular disinfection rotating belt 4 makes one rotation and the disinfection is no longer necessary, disinfection is continued as long as the disinfecting liquid remains, and the necessary amount of disinfecting liquid is calculated in advance and the disinfecting liquid is put into the casing. In many cases, disinfectant wasted even when stored in the tank. In addition, when the disinfecting solution is consumed and the next disinfecting solution is replenished, it must be replenished artificially in a timely manner, and the management is troublesome, and the disinfecting rotating belt 5 is always in pressure contact with the disinfecting rotating belt 4. Therefore, the sterilization rotating belt 5 is significantly distorted and worn, and not only maintenance costs such as replacement and replacement labor costs are increased during long-term use, but also the disinfection rotating belt 5 is not covered. Since the disinfection rotary belt 4 is pressed even when the travel is stopped, when the travel of the disinfection rotary belt 4 is resumed, a contact stain with the disinfection rotation belt 5 or a solidified stain of the disinfecting liquid is attached to the surface of the belt 4. There was also a problem that it required labor that had to be removed artificially because it caused a sense of contamination.

[0019]
Next, an example of use in the case where the rotating belt sanitizer according to the present embodiment is used on the revolving side of the rotating belt of the escalator will be described together with its operation.
As in the conventional example shown in FIG. 9, the rotating belt sanitizing and washing device constructed as described above and assembled in the housing 23 is applied with the sanitizing washing liquid applied to the retraction side of the endless annular rotating belt in the escalator. The roller 61 side is installed with the sterilization washing liquid storage tank 65 side facing forward, and the driving rollers 21 and 22 are brought into pressure contact with the rotating belt A. When the escalator is activated and the traveling of the sterilization cleaning rotating belt A is started, the driving rollers 21 and 22 of the sterilization cleaning device are rotated by the frictional force with the sterilization cleaning rotating belt A. The rotation of the drive roller 21 is transmitted to the flywheel 29 through the rotation shaft 24, the V pulley 25, the V belt 26, the acceleration V pulley 27, and the rotation shaft 28, and the weight 30 causes a centrifugal force by the rotation of the flywheel 29. To move to the outer peripheral side of the flywheel 29. Due to the movement of the weight 30 to the outer peripheral side, the operating pin 33 is axially moved to the inside of the frame B via the guide piece 31, the operating claw 34, and the flange 35. This axial movement is transmitted to the engaging / disengaging claw operating piece 40 through the transmission piece 38 and the swinging rod 39, and the engaging / disengaging claw 40a at the lower end thereof is swung to the sterilization cleaning liquid application roller lifting shaft 42 side.
[0020]
On the other hand, the rotation of the drive roller 22 is caused by the rotation shaft 43, the V pulley 44, the V belt 45, the deceleration V pulley 46, the rotation shaft 47, and the reduction gear shaft 48, the cylindrical gear 55, the worm gear via the reduction gear groups 48 to 53. 56 is decelerated and rotated. The cylindrical gear 55 is meshed with the short diameter side of the eccentric gear 57 before the start of the sterilizing and washing device, and on the central shaft side of the flat cam 73 of the worm wheel 72 meshed with the worm gear 56, Since the guide pin 75 of the piston drive arm 74 is located, the eccentric gear 57 and the worm wheel 72 also start to rotate at a predetermined speed when the speed reduction rotating shaft 54 starts to rotate. When the eccentric gear 57 is rotated to the longer diameter side, the sterilization cleaning liquid application roller elevating shaft 42 is raised to its upper limit and at the same time is engaged with the engagement / disengagement claw 40 a of the engagement / disengagement claw operating piece 40. When the rotation of the eccentric gear 57 and the cylindrical gear 55 further proceeds after the sterilization cleaning liquid application roller lifting shaft 42 is locked to the engagement / disengagement claw 40 a, the eccentric gear 57 is disengaged from the cylindrical gear 55. As a result, the long diameter side of the spring 58 is flipped upward.
[0021]
When the sterilization cleaning liquid application roller lifting shaft 42 is raised, as shown in FIG. 4, the free end portion of the movable frame C is also lifted around the shaft 59 at the same time. The tray 60, the sterilization cleaning liquid application roller 61, the sterilization cleaning liquid supply roller 62, and the squeezing roller 63 are also raised integrally, and the sterilization cleaning liquid application roller 61 is in pressure contact with the sterilization cleaning rotating belt A. After the sterilization cleaning liquid application roller 61 and the sterilization cleaning rotary belt A are pressed against each other, after a lapse of time determined by the gear ratio between the worm gear 56 and the worm wheel 72, that is, the flat surface of the worm wheel 72. While the guide pin 75 of the piston drive arm 74 guided by the cam 73 moves from the shortest diameter portion to the longest diameter portion of the flat cam 73, the piston drive arm 74 pulls up the piston 64b of the sterilization washing liquid supply pump 64, When the sterilization washing liquid a is sucked into the sterilization washing liquid supply pump 64 from the sterilization washing liquid storage tank 65 and the guide pin 75 of the drive arm 74 reaches the shortest diameter part from the longest diameter part of the shaft of the flat cam 73, the guide pin 75 is pulled to the rotating shaft side of the flat cam 73 by the elasticity of the spring 77, so that the piston drive arm 74 is connected to the piston of the sterilization cleaning liquid supply pump 64. Is lowered tons 64b, aspirated sterilization cleaning fluid a in the cylinder 64a is supplied to the sterilization cleaning liquid supply tray 60 via the flexible pipe 67 from the outlet 69.
[0022]
The sterilization cleaning liquid a supplied to the sterilization cleaning liquid supply tray 60 is applied to the sterilization cleaning liquid application roller 61 after the amount of adhesion is adjusted by the sterilization cleaning liquid supply roller 62 and the squeezing roller 63, and then the sterilization cleaning liquid is applied. It is applied to the rotating belt A. In order to set the application interval of the sterilization cleaning liquid a to the sterilization cleaning rotary belt A, for example, every two hours, the worm wheel 72 is rotated halfway while two hours elapse with a combination of the rotation speed and the rotation speed of the drive roller 22. Thus, the reduction ratio of the reduction pulley 46, the reduction gear groups 48 to 53, the worm gear 56, and the worm wheel 72 is adjusted. When adjusted in this manner, a predetermined amount of the sterilization cleaning liquid a is supplied to the sterilization cleaning liquid supply tray 60 every two hours, and the sterilization cleaning liquid a is applied to the sterilization cleaning rotating belt A.
In order to replenish the sterilization cleaning liquid a in the sterilization cleaning liquid storage tank 65 after the sterilization cleaning liquid a in the sterilization cleaning liquid storage tank 65 is consumed, the sterilization cleaning liquid storage tank 65 is removed from the frame B and the cap is removed. Open and replenish with disinfectant cleaning solution a. At this time, the sterilization cleaning liquid supply port 70 of the sterilization cleaning liquid storage tank 65 is provided with an opening / closing valve that closes the sterilization cleaning liquid supply port 70 when the connection with the tank attachment / detachment port 71 is released. The sterilization cleaning liquid a does not leak from the cleaning liquid storage tank 65.
[0023]
When the operation of the escalator is stopped and the traveling of the sterilization cleaning rotating belt A is stopped, the driving rollers 21 and 22 also stop their rotation. When one of the drive rollers 21 stops rotating, the flywheel 29 connected thereto stops and the centrifugal force of the weight 30 does not work, so that the operating claw 34 becomes free and the operating pin is operated by the elasticity of the spring 37. Reference numeral 33 denotes a flange 35 for disabling the operation claw 34 to move the operation pin 33 axially outside the frame B. When the operating pin 33 is pivoted to the outside of the frame B, the transmission piece 38 and the swinging rod 39 are released from being pressed against the engaging / disengaging claw operating piece 40. And the disengagement / claw claw 40a of the engagement / disengagement claw operating piece 40 by its own weight such as the disinfection / cleaning supply tray 60, the disinfection / cleaning liquid application roller 61, the disinfection / cleaning liquid supply roller 62, and the eccentric gear 57 attached to the movable frame C. The free end portion of the movable frame C descends about the shaft 59, and the short side of the eccentric gear 57 and the cylindrical gear 55 are engaged. When the free end portion of the movable frame C is lowered, the contact between the sterilization cleaning liquid application roller 61 and the sterilization cleaning rotary belt A is released, and the old state is restored.
[0024]
The above shows the case where the rotating belt sterilizer is completely operated for one cycle. However, when the traveling of the sterilized cleaning rotating belt A is stopped during the operation, for example, the cylindrical gear 55 of the speed reduction rotating shaft 54 is stopped. And the eccentric gear 57 of the sterilization cleaning liquid application roller lifting shaft 42 are engaged with each other, and the sterilization cleaning liquid application roller lifting shaft 42 is still engaged with the engagement / disengagement claw 40a of the engagement / disengagement claw operating piece 40 in the middle of the ascent. When the rotation of the driving rollers 21 and 22 is stopped in a state where there is no sterilization, the sterilization cleaning liquid application roller elevating shaft 42 stops in the middle of ascending. At this time, when the driving roller 21 is stopped, the operating pin 33 of the flywheel 29 is restored to the old state by the elasticity of the spring 37, and the pressing of the swinging rod 39 against the engaging / disengaging claw operating piece 40 is released. Although it is going to descend, since the cylindrical gear 55 and the eccentric gear 57 are meshed with each other, the descending is prevented. When the traveling of the sterilization cleaning rotary belt A is resumed, the engagement / disengagement claw 40a of the engagement / disengagement claw operating piece 40 swings toward the sterilization / cleaning liquid application roller elevating shaft 42 side in the same manner as described above. Since the rotation is resumed from the state at the time of the rotation stop, when the rotation speed of the cylindrical gear 55 and the eccentric gear 57 before the rotation stop and after the restart of the rotation becomes a predetermined rotation speed, that is, after a predetermined time elapses. Similarly, after the sterilization washing liquid a is supplied, the oldness is restored. Even when the sterilization cleaning rotating belt A rotates in the reverse direction, the rotating shafts and the rotating body rotate in the reverse direction to the above and perform the same operation.
[0025]
In the present embodiment, what is configured and operates as described above is shown, but is not limited to the above-described configuration. For example, the speed reduction means can use an already known speed reduction means such as a variable pulley or a variable speed reduction gear so that the application interval of the sterilization cleaning liquid can be appropriately adjusted, or the amount and frequency of supply of the sterilization cleaning liquid can be adjusted. Naturally, it can be changed or selected as appropriate within the scope of the present invention, such as making it variable by changing the capacity of the pump.
[0026]
【The invention's effect】
Since the present invention is configured as described above, the contact between the sanitization cleaning rotary belt and the sanitization cleaning liquid application roller is separated when the sanitization cleaning rotary belt stops traveling, and is contacted during travel. The sterilization cleaning rotating belt and the sterilization cleaning liquid application roller prevent distortion and wear of the sterilization cleaning rotating belt or stains on the sterilization cleaning rotating belt as much as possible. Supply only the necessary amount to eliminate wasteful consumption of the sterilization cleaning solution, and provide a timer function to the device itself, enabling periodic automatic replenishment of the sterilization cleaning solution to reduce the maintenance cost of the device. it can.
