【発明の属する技術分野】
この発明は、保守作業時等に多数の踏板が連結された踏板鎖を低速駆動する乗客コンベヤーの低速運転装置に関する。
【0002】
【従来の技術】
乗客コンベヤーは、無端状をなし多数の踏板が連結されて主枠内を循環移動する踏板鎖が設けられ、また減速機及び減速機の入力軸に連結された電動機からなる駆動機が主枠に設けられる。そして、電動機が付勢されることにより駆動機の駆動手段に係合された踏板鎖が駆動される。このような乗客コンベヤーにおいて、据付現場での組立時、試運転時又は保守点検時に踏板鎖の低速駆動が行われるが、従来次に述べる低速運転装置によって低速運転が行われていた。

【発明が解決しようとする課題】
上記のような従来の乗客コンベヤーの低速運転装置は、多数の部品によって構成されているので各部品の製作、それらの組立に関わる費用が嵩むという問題点があった。また、手動ハンドルの操作のために多大な労力を要すると共に、試運転のために長時間の作業が必要となって試運転作業の能率が低いという問題点があった。
【0006】
この発明は、かかる問題点を解消するためになされたものであり、簡易な構成であって容易に試運転作業を行うことができる乗客コンベヤーの低速運転装置を得ることを目的とする。
【0007】
【課題を解決するための手段】
この発明に係る乗客コンベヤーの低速運転装置においては、無端状をなし多数の踏板が連結されて乗客コンベヤーの主枠内を循環移動する踏板鎖、主枠に設けられて踏板鎖を駆動する駆動機の要部を形成し出力軸を介して踏板鎖に係合されて、入力軸に伝動機構を介して係合された通常運転電動機によって動作する減速機と、減速機の入力軸に固定された第一歯車及びこの第一歯車とかみ合う第二歯車からなる歯車機構と、主枠に着脱自在に装備されて出力軸に歯車機構の第二歯車が装着された低速運転電動機とが設けられて、低速運転電動機によって乗客コンベヤーが低速運転される。
【0008】
【発明の実施の形態】
実施の形態1.
図1は、この発明の実施の形態の一例を示す図で、乗客コンベヤーの駆動機箇所の要部平面図である。乗客コンベヤーには図示が省略してあるが、無端状をなし多数の踏板が連結されて主枠内を循環移動する踏板鎖が設けられる。そして図において、主枠に設けられて踏板鎖を駆動する駆動機1の要部を形成し、出力軸2を介して踏板鎖に係合された減速機3が設けられる。
【0009】
また、駆動機1に通常運転電動機4が設けられて、通常運転電動機4の出力軸に設けられた第一Vベルト車5、減速機3の入力軸6に設けられた第二Vベルト車7並びに第一Vベルト車5及び第二Vベルト車7に巻掛けられたVベルト8からなる伝動機構9によって通常運転電動機4の動作が減速機3に伝動される。また、主枠に取付ボルト10によって着脱自在に装備されたブラケット11に携帯可能な小形電動機からなる低速運転電動機12が装着される。
【0010】
そして、減速機3の入力軸6に固定された第一歯車13及び第一歯車13とかみ合い低速運転電動機12の出力軸に固定された第二歯車14からなる歯車機構15が設けられる。なお、図示が省略してあるが低速運転電動機12を付勢、消勢、正転、逆転させる制御器、また低速運転電動機12を電源に接続するコードが設けられている。
【0011】
上記のように構成された乗客コンベヤーの低速運転装置において、通常時は取付ボルト10によってブラケット11が取り外されて、低速運転電動機12が主枠から撤去されている。そして、通常時は駆動機1の通常運転電動機4によって減速機3を介して踏板鎖が駆動されて踏板鎖に連結された多数の踏板が主枠内を循環移動する。また、乗客コンベヤーの据付現場での組立時、試運転時又は保守点検時に次に述べるようにして踏板鎖の低速駆動が行われる。
【0012】
すなわち、踏板鎖の低速駆動時には取付ボルト10によってブラケット11を介して低速運転電動機12が主枠に装着されて、第二歯車14が第一歯車13に係合され、また低速運転電動機12のコードが電源に接続される。そして、試運転作業員が制御器を操作して低速運転電動機12を付勢することにより踏板鎖が、すなわち乗客コンベヤーが上昇又は下降の適宜な方向へ低速駆動される。
【0013】
そして、図1に示す乗客コンベヤーの低速運転装置は、駆動機1を形成した減速機3の入力軸6に、歯車機構15によって低速運転電動機12を着脱自在に連結する簡易な構成であるので製造費を節減することができる。また、低速運転電動機12によって歯車機構15を介して減速機3が動作し、乗客コンベヤーが低速により動力駆動される。
【0014】
このため、乗客コンベヤーの低速運転における人力駆動が解消されて低速運転を省力化することができる。したがって、試運転作業時間を短縮でき、乗客コンベヤーの試運転作業の能率を向上することができる。なお、低速運転作業が終了すると、取付ボルト10によってブラケット11、低速運転電動機12が主枠から撤去されて、歯車機構15による低速運転電動機12と減速機3の入力軸6との係合関係が解消される。
【0015】
【発明の効果】
この発明は以上説明したように、無端状をなし多数の踏板が連結されて乗客コンベヤーの主枠内を循環移動する踏板鎖、主枠に設けられて踏板鎖を駆動する駆動機の要部を形成し出力軸を介して踏板鎖に係合されて、入力軸に伝動機構を介して係合された通常運転電動機によって動作する減速機と、減速機の入力軸に固定された第一歯車及びこの第一歯車とかみ合う第二歯車からなる歯車機構と、主枠に着脱自在に装備されて出力軸に歯車機構の第二歯車が設けられた低速運転電動機とを設けて、低速運転電動機によって乗客コンベヤーを低速運転するものである。
【0016】
これによって、乗客コンベヤーの試運転時等に踏板鎖の低速運転が次に述べるように行われる。すなわち、低速運転電動機が乗客コンベヤーの主枠に装着されて、歯車機構によって減速機の入力軸に連結される。そして、低速運転電動機が作業員によって人為操作され、踏板鎖、すなわち乗客コンベヤーが上昇又は下降の適宜な方向へ低速駆動される。そして、乗客コンベヤーの低速運転装置が、歯車機構によって低速運転電動機を駆動機における減速機の入力軸に着脱自在に連結する簡易な構成であるので、製造費を節減する効果がある。また、低速運転電動機によって歯車機構を介して減速機が動作して乗客コンベヤーが低速で動力駆動される。このため、乗客コンベヤーの低速運転における人力駆動が解消され、低速運転を省力化することができる。したがって、試運転作業時間を短縮でき、乗客コンベヤーの試運転作業の能率を向上する効果がある。
