【産業上の利用分野】
この発明は、例えば、自動車や家電製品の組立作業に用いられるオーバーヘッドコンベヤのトロリ走行レールの分岐装置に関する。
【0002】
【従来の技術】
この種の装置としては、例えば、特開平4−116091号公報および特開平5−280002号公報に開示されているように、本線レールと支線レールの分岐点に、レール長さ方向と交差する方向にのびた台車走行レールが設けられ、台車走行レールに台車がのせられ、台車に、本線連絡レールおよび支線連絡レールが装備され、本線レールの前端部および後端部に本線位置決め用係合凹部が、本線連絡レールの後端部および前端部に本線位置決め係合凸部がそれぞれ設けられ、本線レールの前端部および支線レールの後端部に支線位置決め用係合凹部が、支線連絡レールの後端部および前端部に支線位置決め用係合凸部がそれぞれ設けられ、本線位置決め用係合凹部および支線位置決め用係合凹部が、横向きであり、台車の移動によって、本線位置決め用係合凹部に本線位置決め用係合凸部が、支線位置決め用係合凹部に支線位置決め用係合凸部が、それぞれ係合・係合離脱させられるようになされているものが知られている。
【0003】
【従来の技術】
上記従来装置では、台車の水平移動により係合凹部および係合凸部を係合させるようにしているため、係合凹部および係合凸部のはめ合せ公差の条件が非常に厳しいものとなる。そのため、係合凹部および係合凸部の組立および加工にも高い精度が要求されるし、台車等に変形しないだけの剛性を持たせなければならず、装置の構造が複雑となる。
【0004】
この発明の目的は、レールを位置決めするための係合凹部および係合凸部のはめ合せ公差の条件が緩いものであっても、係合凹部および係合凸部を確実に係合させることができるレール分岐装置を提供することにある。
【0005】
【課題を解決するための手段】
この発明によるレール分岐装置は、本線レールと支線レールの分岐点に、レール長さ方向と交差する方向にのびた台車走行レールが設けられ、台車走行レールに台車がのせられ、台車に、本線連絡レールおよび支線連絡レールが装備され、本線レールの前端部および後端部に本線位置決め用係合凹部が、本線連絡レールの後端部および前端部に本線位置決め係合凸部がそれぞれ設けられ、本線レールの前端部および支線レールの後端部に支線位置決め用係合凹部が、支線連絡レールの後端部および前端部に支線位置決め用係合凸部がそれぞれ設けられ、台車の移動によって、本線位置決め用係合凹部に本線位置決め用係合凸部が、支線位置決め用係合凹部に支線位置決め用係合凸部が、それぞれ係合・係合離脱させられるようになされているレール分岐装置において、本線位置決め用係合凹部および支線位置決め用係合凹部が、上向きであり、台車走行レールに、本線レールおよび支線レールより本線連絡レールおよび支線連絡レールが上方レベルに位置させられるように台車を受けるレール踏面が設けられ、レール踏面に、本線位置決め用係合凹部および係合凸部を係合させるように台車を下向きに案内する本線用傾斜面と、支線位置決め用係合凹部および係合凸部を係合させるように台車を下向きに案内する支線用傾斜面とが設けられていることを特徴とするものである。
【0006】
【作用】
この発明によるレール分岐装置では、本線位置決め用係合凹部および支線位置決め用係合凹部が、上向きであり、台車走行レールに、本線レールおよび支線レールより本線連絡レールおよび支線連絡レールが上方レベルに位置させられるように台車を受けるレール踏面が設けられ、レール踏面に、本線位置決め用係合凹部および係合凸部を係合させるように台車を下向きに案内する本線用傾斜面と、本線位置決め用係合凹部および係合凸部を係合させるように台車を下向きに案内する支線用傾斜面とが設けられているから、係合凹部および係合凸部のはめ合せに際し、係合凹部に、これの斜め上から係合凸部がはめ合わされ、最終的に係合凹部の底に係合凸部が当接させられることにより、係合凹部と係合凸部が位置決めされる。
【0007】
【実施例】
この発明の実施例を、図面を参照してつぎに説明する。
【0008】
以下の説明において、前後とは、図1を基準として、図1の下側を前、これと反対側を後といい、左右とは、図1の左側を左、図1の右側を右というものとする。
【0009】
図1および図2を参照すると、オーバーヘッドコンベヤは、本線レール11および支線レール12と、本線レール11および支線レール12にそって走行するトロリ13と、本線レール11を基準線として、分岐点において本線レール11を、本線レール11と支線レール12に分岐させている分岐装置14とを備えている。
【0010】
本線レール11は、分岐装置14を経由して、前後方向にのびており、支線レール12は、分岐装置14から左斜め前方に向かってのびている。本線レール11および支線レール12は、いずれも左方開口横断面コの字状のものである。
【0011】
分岐装置14は、図示しない天井から吊下げられている左右一対の水平支持バー21に渡し止められている左右方向にのびた前後一対の水平台車走行レール22と、両台車走行レール22の間隔にほぼ等しい幅をもつ方形状台車本体23および両台車走行レール22に2つずつのせられている4つの車輪24よりなる台車25と、台車25に吊下げブラケット26を介してそれぞれ取付けられている直線状本線連絡レール27および曲線状支線連絡レール28と、支持バー21に取付けられかつ台車25に連結されているピストンロッド31を有している台車移動用流体圧シリンダ32とを備えている。
【0012】
本線レール11の前端部頂面に第1位置決め部材41が、本線レール11の後端部頂面に第2位置決め部材42が、支線レール12の後端部頂面に第3位置決め部材43がそれぞれ設けられている。本線連絡レール27の後端部頂面に第4位置決め部材44が、本線連絡レール27の前端部頂面に第5位置決め部材45が、支線連絡レール28の後端部頂面に第6位置決め部材46が、支線連絡レール28の前端部頂面に第7位置決め部材47がそれぞれ設けられている。
【0013】
本線レール11の前端部底面には前方突出水平板状後レール受け48が設けられている(図4参照)。さらに、詳しく図示しないが、後レール受け48と前後の向きを異にする後方突出水平板状前レール受け49が、本線レール11の後端部底面および支線レール12の後端部底面にそれぞれ設けられている。
【0014】
第1位置決め部材41は、図3および図4に詳しく示すように、垂直方形板状のもので、右縁部に略U字状右斜め上向き本線位置決め用係合凹部51を、左縁部に略U字状左斜め上向き支線位置決め用係合凹部52をそれぞれ有している。第2位置決め部材42は、詳しく図示しないが、第1位置決め部材41と同形状のものであるが、第1位置決め部材41の支線位置決め用係合凹部52に相当する凹部はダミーであって、本線位置決め用係合凹部51のみを有している。第3位置決め部材43は、図2に概略示すように、第1位置決め部材41の右角を丸めたようなものであって、左縁部に略U字状左斜め上向き支線位置決め用係合凹部52を有している。
【0015】
第4位置決め部材44および第5位置決め部材45は、前後の向きは異にするが、同一構造のものである。第4位置決め部材44は、後方突出水平丸棒状本線位置決め用係合凸部53を、第5位置決め部材45は、前方突出水平丸棒状本線位置決め用係合凸部53をそれぞれ有している。第4位置決め部材44について、図3および図4に詳しく示されている。第6位置決め部材46は、第4位置決め部材44と同一形状のものであって、後方突出水平丸棒状支線位置決め用係合凸部54を有している。第7位置決め部材47は、第5位置決め部材45と同一形状のものであって、前方突出水平丸棒状支線位置決め用係合凸部54を有している。
【0016】
図3に示すように、台車走行レール22のレール踏面61に車輪がのせられている状態で本線レール11より本線連絡レール27が上方レベルに位置させられている。
【0017】
図2に示すように、レール踏面61の左端近くと中央やや右寄りの2か所には略V字状本線連絡用左限位置決め凹所62が、レール踏面61の右端近くと中央やや左寄りの2か所には略V字状支線連絡用右限位置決め凹所63がそれぞれ設けられている。また、右端の右限位置決め凹所63の右斜め上には台車浮上り防止用車輪止め64が設けられている。左限位置決め凹所62は、左斜め上向きの本線用傾斜面65を、右限位置決め凹所63は、右斜め上向きの支線用傾斜面66をそれぞれ有している。
【0018】
第1および第2図は、流体圧シリンダ32のピストンロッド31が突出させられ、車輪24が右限位置決め凹所63に入り込んでいて、台車25が右限に位置させられ、本線レール11の前端部が支線連絡レール28によって支線レール12の後端部と接続されている状態を示している。
【0019】
この状態から流体圧シリンダ32のピストンロッド31を退入させて、台車25を左動させると、図3に示すように、右限位置決め凹所63から車輪24が転がり出る。さらに、台車25を左動させると、車輪24がレール踏面上61を転動し、やがて、左限位置決め凹所62に入り込む。このときに、図3において、2点鎖線で軌跡を示すように、車輪24が本線用傾斜面65を転がり落ちると同時に、本線位置決め用係合凹部51に向かって本線位置決め用係合凸部53が左斜め下に向かって移動させられ、最終的に、本線位置決め用係合凹部53の底に本線位置決め用係合凸部53に当接させられる。さらに、これと同時に、本線連絡レール27の後端部が後レール受け48で、本線連絡レール27の前端部が前レール受け28でそれぞれ受けられる。これにより、本線レール11の前端部が本線連絡レール27によって本線レール27の後端部と位置決めされた状態で接続される。この接続状態となると、台車25の重量は、本線連絡レール27を介して本線レール11によって支えられるため、台車25および台車走行レール22の剛性はさほど必要無く、その軽量化および簡素化を図ることができる。
【0020】
この状態から、流体圧シリンダ32のピストンロッド31を突出させて台車25を右限まで移動させると、再び、図1および図2に示す状態となる。
【0021】
上記において、係合凹部51,52は、斜め上を向いたU字状のものであったが、これに代わり、真上を向いたV字状のようにものでもよい。
【0022】
また、レールを2つのレールに分岐させる場合についての説明としたが、2つのレールを1つのレールに合流させる場合に適用できることは、勿論である。
【0023】
【発明の効果】
この発明によれば、係合凹部および係合凸部のはめ合せに際し、係合凹部に、これの斜め上から係合凸部がはめ合わされ、最終的に係合凹部の底に係合凸部が当接させられることにより、係合凹部と係合凸部が位置決めされるから、係合凹部および係合凸部のはめ合せ公差の条件が緩いものであっても、係合凹部および係合凸部を確実に係合させることができる。
