Description

【０００１】
【発明の属する技術分野】
本発明は、自動車ボディー等の大型の被搬送物を吊り下げて搬送する吊下搬送装置等に使用される被搬送物吊下搬送用ハンガーに関するものである。
【０００２】
【従来の技術】
この種の一般的な被搬送物吊下搬送用ハンガーは、被搬送物の左右両側辺の前後二箇所を各別に支持する四つの支持部を、被搬送物を跨ぐ門形のハンガーの側枠下端に設けたものであるが、他の手段、例えばテーブルリフターやランニングフォーク、ドロップリフター等との間での被搬送物の上下方向の積み降ろしを可能にするために、ハンガー側枠を横側方に開動させたり、各支持部を垂直支軸の周りに水平に回動させて、各支持部を被搬送物の上下移動を許す横側方退避位置へ逃がすことが出来るように構成されていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、ハンガーとの間で被搬送物を受け渡しするドロップリフター等、他の手段の被搬送物の支持用治具の配置や当該治具の支持構造等により、前記のようにハンガー側枠を横側方に開動させたり、ハンガー側の各支持部を垂直支軸の周りに水平に回動させることが出来ない場合があった。換言すれば、ハンガーとの間で被搬送物を受け渡しする他の手段の側に、前記のようにハンガー側枠の横側方への開動やハンガー側の各支持部の水平回動を妨害しない構成でなければならないという制約が与えられることになり、被搬送物を最も安定良く安全に支持するという観点からの設計上の自由度が制限される結果となっていた。
【０００４】
【課題を解決するための手段】
本発明は上記のような従来の問題点を解消し得る被搬送物吊下搬送用ハンガーを提供することを目的とするものであって、請求項１に記載の本発明では、その手段を後述する実施形態の参照符号を付して示すと、被搬送物Ｗの左右両側辺を支持する複数の支持部（支持用治具８，１０）を備えた吊下搬送用ハンガーであって、前記複数の支持部（支持用治具８，１０）の内、少なくとも一つの支持部（支持用治具１０）は、被搬送物Ｗの搬送方向に対する横側方に位置するハンガー側枠５ａ，５ｂから被搬送物側へ延出する略水平の支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの外端上側に設けられると共に、当該被搬送物支持台９ａ，９ｂは、前記ハンガー側枠５ａ，５ｂに設けられた支持部材１１に内端寄り底部が支持されると共に、内端が昇降駆動手段１２に連結されて略垂直に昇降可能に支持され、当該被搬送物支持台９ａ，９ｂの内端を前記昇降駆動手段１２で略垂直に引き上げることにより、当該被搬送物支持台９ａ，９ｂが前記支持部材１１に外端底部が支持された倒立格納姿勢Ｖに切り換わるように構成された被搬送物吊下搬送用ハンガーにおいて、前記ハンガー側枠５ａ，５ｂには、支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの内端が上動するのを阻止する作用位置と当該内端の上動を許す退避位置とに切り替え自在な係止手段１９が設けられた構成となっている。
【０００５】
上記構成の本発明を実施するについて、請求項２に記載のように、前記支持部材１１に支持される被搬送物支持台９ａ，９ｂの底部は、突出円弧形に形成することが出来る。
【０００６】
又、請求項３に記載の本発明では、被搬送物Ｗの左右両側辺を支持する複数の支持部（支持用治具８，１０）を備えた吊下搬送用ハンガーであって、前記複数の支持部（支持用治具８，１０）の内、少なくとも一つの支持部（支持用治具１０）は、被搬送物Ｗの搬送方向に対する横側方に位置するハンガー側枠５ａ，５ｂから被搬送物側へ延出する略水平の支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの外端上側に設けられると共に、当該被搬送物支持台９ａ，９ｂは、前記ハンガー側枠５ａ，５ｂに設けられた支持部材１１に内端寄り底部が支持されると共に、内端が昇降駆動手段１２に連結されて略垂直に昇降可能に支持され、当該被搬送物支持台９ａ，９ｂの内端を前記昇降駆動手段１２で略垂直に引き上げることにより、当該被搬送物支持台９ａ，９ｂが前記支持部材１１に外端底部が支持された倒立格納姿勢Ｖに切り換わるように構成された被搬送物吊下搬送用ハンガーにおいて、前記支持部材１１に支持される被搬送物支持台９ａ，９ｂの底部が、突出円弧形に形成される。上記請求項１〜３に記載の本発明を実施する場合、具体的には、前記被搬送物支持台９ａ，９ｂは、両側板１３ａ，１３ｂとこの両側板１３ａ，１３ｂを互いに連結一体化する連結部材１４ａ〜１４ｃから構成し、前記支持部材１１は、被搬送物支持台９ａ，９ｂの前記両側板１３ａ，１３ｂを各別に支持する鍔付きローラー１５ａ，１５ｂから構成することが出来る。
【０００７】
前記昇降駆動手段１２は、前記被搬送物支持台９ａ，９ｂの内端左右両側に軸支された左右一対のガイドローラー１６ａ，１６ｂと、これら各ガイドローラー１６ａ，１６ｂと係合するように前記ハンガー側枠５ａ，５ｂに設けられた昇降用ガイドレール１７ａ，１７ｂと、前記被搬送物支持台９ａ，９ｂの内端と前記ハンガー側枠５ａ，５ｂとの間に介装されたシリンダーユニット１８とから構成することが出来る。
【０００８】
【発明の実施の形態】
以下に本発明の好適実施形態を添付図に基づいて説明すると、図１〜図３に於いて、１は本発明の被搬送物吊下搬送用ハンガー２を備えた吊下搬送用走行体であって、架設された２列のガイドレール３に自走可能に吊り下げられて、Ｐ１地点とＰ２地点との間の直線走行経路を正逆往復走行するものであり、その自走手段としては、モーター駆動の自走用車輪方式や、走行経路に沿って敷設されたラックギヤ等に咬合するモーター駆動の自走用歯車方式、走行経路に沿って掛張された駆動チエンや駆動ワイヤーに吊下搬送用走行体１が連結される方式等、状況に応じて従来周知の任意の自走手段が利用されるので、ここでは具体構造の図示および説明は省略する。
【０００９】
前記吊下搬送用走行体１の下側には、自動車ボディー等の被搬送物Ｗを挟むように位置する左右一対前後二組のハンガー側枠４ａ，４ｂ、５ａ，５ｂから成る門形の被搬送物吊下搬送用ハンガー２が取り付けられている。前側左右一対のハンガー側枠４ａ，４ｂの下端には、図１に示すように、内側へ直角に延出する支持姿勢と前方へ９０度旋回した退避姿勢との間で垂直支軸の周りで水平に回転可能な被搬送物支持台７ａ，７ｂが取り付けられ、各被搬送物支持台７ａ，７ｂの先端上側に支持用治具（支持部）８が付設されている。この前側左右一対の被搬送物支持台７ａ，７ｂの姿勢切換手段（水平旋回駆動手段）は、シリンダーユニット６（図２参照）利用の流体圧駆動方式のものや、歯車やチエン等を介しての、又は直結式のモーター駆動方式等が利用される。
【００１０】
後ろ側左右一対のハンガー側枠５ａ，５ｂの下端に取り付けられた被搬送物支持台９ａ，９ｂの詳細構造を図４〜図６に基づいて説明すると、各被搬送物支持台９ａ，９ｂは、ハンガー側枠５ａ，５ｂから被搬送物Ｗ側へ延出する略水平の支持姿勢Ｈと、ハンガー側枠５ａ，５ｂに略沿った倒立格納姿勢Ｖとに切り換え自在なもので、水平支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの外端（先端）上側に支持用治具（支持部）１０が付設されると共に、ハンガー側枠５ａ，５ｂに設けられた支持部材１１により当該水平支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの内端寄り底部が支持され、当該被搬送物支持台９ａ，９ｂの内端が昇降駆動手段１２に連結されて略垂直に昇降可能に支持されている。
【００１１】
更に詳述すると、被搬送物支持台９ａ，９ｂは、両側板１３ａ，１３ｂを連結部材１４ａ〜１４ｃで互いに連結一体化したもので、図４に示すように、両側板１３ａ，１３ｂの底辺１３ｃは突出円弧形に形成され、前記支持部材１１は、当該両側板１３ａ，１３ｂの円弧形底辺１３ｃを各別に支持すると共に、その鍔部で被搬送物支持台９ａ，９ｂを位置決めする左右一対の同心状の鍔付きローラー１５ａ，１５ｂから構成されている。
【００１２】
昇降駆動手段１２は、被搬送物支持台９ａ，９ｂの内端両外側面に同心状に軸支された左右一対のガイドローラー１６ａ，１６ｂと、これら各ガイドローラー１６ａ，１６ｂを挟むようにハンガー側枠５ａ，５ｂに垂直に固着された昇降用ガイドレール１７ａ，１７ｂと、各ハンガー側枠５ａ，５ｂにシリンダー本体の上端が軸支され且つピストンロッド１８ａの下端が被搬送物支持台９ａ，９ｂの内端中央部（両側板１３ａ，１３ｂの中間位置）に軸支された垂直向きのシリンダーユニット１８とから構成されている。
【００１３】
１９は係止手段であって、各ハンガー側枠５ａ，５ｂに、水平支持姿勢Ｈにある被搬送物支持台９ａ，９ｂの内端上側に当接する作用位置と当該被搬送物支持台９ａ，９ｂの内端の上動を許す退避位置との間で水平出退移動自在に支持された同心状の一対のピン２０ａ，２０ｂと、各ピン２０ａ，２０ｂを連結板２１ａ，２１ｂを介して出退駆動する一対のシリンダーユニット２２ａ，２２ｂとから構成されている。
【００１４】
上記構成の左右一対の被搬送物支持台９ａ，９ｂは、図４に実線で示すように水平支持姿勢Ｈにあるとき、その外端上側の支持用治具１０で被搬送物Ｗの側辺を支持することが出来るが、このとき係止手段１９の両ピン２０ａ，２０ｂを作用位置に突出させておくことにより、当該被搬送物支持台９ａ，９ｂに作用する、支持部材１１（鍔付きローラー１５ａ，１５ｂ）との接点を支点とする外端下降方向（内端上動方向）のモーメントをピン２０ａ，２０ｂで受け止めさせ、当該モーメントがシリンダーユニット１８のピストンロッド１８ａ側に圧縮力として作用するのを防止出来る。
【００１５】
水平支持姿勢Ｈにある被搬送物支持台９ａ，９ｂを倒立格納姿勢Ｖに切り換えるときは、作用位置にある係止手段１９の両ピン２０ａ，２０ｂをシリンダーユニット２２ａ，２２ｂにより外側（互いに離間する方向）に後退移動させ、これら両ピン２０ａ，２０ｂを退避位置に切り換えて、被搬送物支持台９ａ，９ｂの内端の上動を許す状態に切り換える。係る状態で昇降駆動手段１２の両シリンダーユニット１８を、収縮するピストンロッド１８ａで被搬送物支持台９ａ，９ｂの内端を引き上げるように作動させる。このとき被搬送物支持台９ａ，９ｂの内端は、ガイドローラー１６ａ，１６ｂとハンガー側枠５ａ，５ｂ側の昇降用ガイドレール１７ａ，１７ｂとにより垂直にのみ昇降可能に支持されているので、その円弧形底辺１３ｃがハンガー側枠５ａ，５ｂ側の支持部材１１（鍔付きローラー１５ａ，１５ｂ）に転動可能に支持されている状態で内端が真上に引き上げられることになり、被搬送物支持台９ａ，９ｂは、図４に仮想線で示すように、支持用治具１０のある外端部が下側に膨らむ円弧状経路を経由するようにして倒立格納姿勢Ｖに切り換えられる。この倒立格納姿勢Ｖに達した被搬送物支持台９ａ，９ｂは、吊り上げられた内端に対し、支持部材１１（鍔付きローラー１５ａ，１５ｂ）に支持される下向きの外端部が内側に位置するように若干傾斜する姿勢でシリンダーユニット１８により吊り下げられた状態で安定する。
【００１６】
倒立格納姿勢Ｖにある被搬送物支持台９ａ，９ｂを水平支持姿勢Ｈに戻すときは、シリンダーユニット１８のピストンロッド１８ａを伸張させて倒立格納姿勢Ｖにある被搬送物支持台９ａ，９ｂの上向きの内端を垂直下方へ押し下げることにより、当該被搬送物支持台９ａ，９ｂは、下降に伴ってハンガー側枠５ａ，５ｂ側の支持部材１１（鍔付きローラー１５ａ，１５ｂ）を支点に内側へ水平方向に向きを変えながら移動し、シリンダーユニット１８のピストンロッド１８ａが伸長限に達したとき、図４に実線で示す水平支持姿勢Ｈへの切り換えが完了する。この後、係止手段のピン２０ａ，２０ｂをシリンダーユニット２２ａ，２２ｂにより進出させて作用位置に切り換えることにより、当該ピン２０ａ，２０ｂが水平支持姿勢Ｈの被搬送物支持台９ａ，９ｂの内端上側面に当接し、当該被搬送物支持台９ａ，９ｂを水平支持姿勢Ｈにロックすることが出来る。
【００１７】
図１に示す設備全体の使用方法を説明すると、この設備では、地点Ｐ１に併設された被搬送物積み降ろし手段（図示省略）で吊下搬送用走行体１の被搬送物吊下搬送用ハンガー２に被搬送物Ｗを積み込み、この被搬送物Ｗを地点Ｐ２まで搬送した後、当該地点Ｐ２に併設されたドロップリフターＤＬに移載するか、又はこの逆に、地点Ｐ２に併設されたドロップリフターＤＬから被搬送物Ｗを吊下搬送用走行体１の被搬送物吊下搬送用ハンガー２に積み込み、この被搬送物Ｗを地点Ｐ１まで搬送し、当該地点Ｐ１に併設された被搬送物積み降ろし手段（図示省略）で被搬送物吊下搬送用ハンガー２から被搬送物Ｗを降ろすことが出来る。
【００１８】
而して、地点Ｐ１や地点Ｐ２で被搬送物吊下搬送用ハンガー２に被搬送物Ｗを積み込むときは、被搬送物吊下搬送用ハンガー２の前側左右一対の被搬送物支持台７ａ，７ｂを垂直支軸の周りで水平に前方外側へ９０度旋回させてハンガー側枠４ａ，４ｂから前方へ延出する退避姿勢に切り換えると共に、後ろ側左右一対の被搬送物支持台９ａ，９ｂを先に説明した方法で水平支持姿勢Ｈから倒立格納姿勢に切り換えた状態で、吊下搬送用走行体１を地点Ｐ１又は地点Ｐ２の定位置に停止させる。この後、被搬送物Ｗを支持している前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬを、その被搬送物Ｗが被搬送物吊下搬送用ハンガー２の被搬送物支持レベルより高くなるレベルまで上昇させるが、地点Ｐ１又は地点Ｐ２の被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬと当該地点Ｐ１又は地点Ｐ２に進入してくる吊下搬送用走行体１の被搬送物吊下搬送用ハンガー２とが干渉しないときは、地点Ｐ１又は地点Ｐ２に吊下搬送用走行体１が進入してくる前に、被搬送物Ｗを支持している前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬを、その被搬送物Ｗが被搬送物吊下搬送用ハンガー２の被搬送物支持レベルより高くなるレベルまで上昇させて待機させておくことが出来る。
【００１９】
地点Ｐ１又は地点Ｐ２に吊下搬送用走行体１が到着すれば、前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬが支持する被搬送物Ｗより低い高さに於いて、被搬送物吊下搬送用ハンガー２の前側左右一対の被搬送物支持台７ａ，７ｂを垂直支軸の周りで水平に後方内側へ９０度旋回させてハンガー側枠４ａ，４ｂから内側へ直角に延出する支持姿勢に切り換えると共に、後ろ側左右一対の被搬送物支持台９ａ，９ｂを先に説明した方法でハンガー側枠５ａ，５ｂから内側へ水平に延出する水平支持姿勢Ｈに切り換える。この後、前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬにより支持されている被搬送物Ｗを降下させ、当該被搬送物Ｗを被搬送物吊下搬送用ハンガー２の前側左右一対の被搬送物支持台７ａ，７ｂ及び後ろ側左右一対の被搬送物支持台９ａ，９ｂの各支持用治具８，１０上に乗り移らせる。この状態で吊下搬送用走行体１を走行させると、被搬送物Ｗを支持した被搬送物吊下搬送用ハンガー２と前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬとが干渉するときは、当該被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬをその干渉を避け得るレベルまで下降させた状態で、被搬送物Ｗが積み込まれた吊下搬送用走行体１を走行させれば良い。
【００２０】
上記と逆に、地点Ｐ１や地点Ｐ２で被搬送物吊下搬送用ハンガー２から被搬送物Ｗを降ろすときは、当該地点Ｐ１又は地点Ｐ２の定位置に吊下搬送用走行体１を停止させ、支持姿勢にある四つの被搬送物支持台７ａ，７ｂ，９ａ，９ｂで支持されている被搬送物Ｗより低レベルで待機させているテーブルリフターやランニングフォーク等の被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬを上昇させ、当該被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬで被搬送物Ｗを被搬送物吊下搬送用ハンガー２からすくい上げさせる。この状態で吊下搬送用走行体１を走行させると、被搬送物Ｗをすくい上げた状態の前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬと被搬送物吊下搬送用ハンガー２とが干渉するときは、被搬送物吊下搬送用ハンガー２の前側左右一対の被搬送物支持台７ａ，７ｂを垂直支軸の周りで水平に前方外側へ９０度旋回させてハンガー側枠４ａ，４ｂから前方へ延出する退避姿勢に切り換えると共に、後ろ側左右一対の被搬送物支持台９ａ，９ｂを先に説明した方法で水平支持姿勢Ｈから倒立格納姿勢に切り換え、これら四つの被搬送物支持台７ａ，７ｂ，９ａ，９ｂを平面視に於いて被搬送物Ｗの外側へ変位させた状態で前記被搬送物積み降ろし手段（図示省略）又はドロップリフターＤＬを下降させて、支持する被搬送物Ｗを、吊下搬送用走行体１の走行に伴う被搬送物吊下搬送用ハンガー２の移動経路から下方へ逃がし、この後、吊下搬送用走行体１を走行させれば良い。
【００２１】
以上のように、吊下搬送用走行体１の被搬送物吊下搬送用ハンガー２を使用することが出来るのであるが、この実施形態に於ける被搬送物吊下搬送用ハンガー２の後ろ側左右一対の被搬送物支持台９ａ，９ｂの構成によれば、例えば当該被搬送物吊下搬送用ハンガー２との間で被搬送物Ｗの積み降ろしが行われるドロップリフターＤＬを、図１Ａに実線で示すと共に図４及び図６にそれぞれ仮想線で示すように構成することが出来る。即ち、この種のドロップリフターＤＬは、吊下搬送用走行体１の走行経路の左右両側でそれぞれ昇降用ガイド支柱２３ａ，２３ｂに案内されて昇降する左右一対の昇降キャレッジ２４ａ，２４ｂに被搬送物Ｗの左右両側辺を各別に支持する支持アーム２５ａ，２５ｂを設けたものであるが、これら支持アーム２５ａ，２５ｂは、例えば被搬送物吊下搬送用ハンガー２が支持していた被搬送物Ｗを昇降キャレッジ２４ａ，２４ｂの上昇によりすくい上げた状態に於いて、被搬送物吊下搬送用ハンガー２の各被搬送物支持台７ａ，７ｂ及び９ａ，９ｂが支持姿勢から退避姿勢に切り換わるときの運動を妨害しない位置になければならない。勿論、これら支持アーム２５ａ，２５ｂは、被搬送物吊下搬送用ハンガー２の各支持用治具８，１０による支持位置から遠く離れた位置で被搬送物Ｗを支持するのではなく、当該支持用治具８，１０に隣接する位置で被搬送物Ｗを支持することが出来るものでなければならない。
【００２２】
而して、被搬送物吊下搬送用ハンガー２の前側左右一対の支持用治具８は、退避姿勢に切り換わるとき前方外方へ水平に旋回するものであるから、この支持用治具８に対しては、被搬送物Ｗを支持するときの当該支持用治具８の後方側に隣接する位置で被搬送物Ｗを支持する支持用治具２６を備えた支持アーム２７ａ，２７ｂを設ければ良い。又、後ろ側左右一対の支持用治具１０は前後方向に長いものであるが、退避姿勢に切り換わるとき、平面視に於いてハンガー側枠５ａ，５ｂと重なる位置まで真横外方に移動するものであるから、この支持用治具１０に対しては、被搬送物Ｗを支持するときの当該支持用治具１０の前後両側に隣接する位置で被搬送物Ｗを支持する前後一対の支持用治具２８，２９を各別に備えた前後一対の支持アーム３０ａ，３１ａ及び３０ｂ，３１ｂを設けることが出来る。又、これら各三つの支持アーム２７ａ，３０ａ，３１ａ及び２７ｂ，３０ｂ，３１ｂが取り付けられる昇降キャレッジ２４ａ，２４ｂを、ハンガー側枠５ａ，５ｂの外側に隣接するように配設することが出来る。
【００２３】
この実施形態でのドロップリフターＤＬは、吊下搬送用走行体１の被搬送物吊下搬送用ハンガー２と下方の他の搬送手段等との間で被搬送物Ｗを昇降搬送するものであって、当該下方の他の搬送手段等との間での被搬送物Ｗの受け渡しに必要なため、前記各支持アーム２７ａ，３０ａ，３１ａ及び２７ｂ，３０ｂ，３１ｂは、図３に示すように、昇降キャレッジ２４ａ，２４ｂに対して水平に出退移動自在に支持されている。
【００２４】
尚、上記実施形態では、被搬送物Ｗの左右両側辺の前側はそれぞれ一箇所を支持すれば良いので、従来周知の水平旋回式の被搬送物支持台７ａ，７ｂを利用したが、後ろ側と同様に、前後方向に所要長さを有する領域の少なくとも前後両端二箇所を支持する必要があるときは、後ろ側左右一対の被搬送物支持台９ａ，９ｂと同様の構成の被搬送物支持台を設けることが出来る。又、被搬送物支持台９ａ，９ｂを備えたハンガー側枠５ａ，５ｂは、吊下搬送用走行体１に対して完全に固定されている必要はなく、ドロップリフターＤＬやその他の被搬送物積み降ろし手段との干渉を避けることが出来る範囲で左右横方向に揺動又はスライド可能に構成して、このハンガー側枠５ａ，５ｂの外側への開動と昇降駆動手段１２による被搬送物支持台９ａ，９ｂ内端の引き上げとを組み合わせて、当該被搬送物支持台９ａ，９ｂを倒立格納姿勢Ｖへ切り換えるように構成することも可能である。
【００２５】
【発明の効果】
本発明の吊下搬送用ハンガーは以上のように実施し且つ使用することができるものであって、係る本発明の吊下搬送用ハンガーによれば、ハンガー側枠に支持された少なくとも一つの被搬送物支持台が、ハンガー側枠から被搬送物側へ略水平に延出する支持姿勢から昇降駆動手段による内端の引き上げにより倒立格納姿勢に切り換わるように構成されているので、当該被搬送物支持台に関しては、被搬送物を支持する位置と当該被搬送物から横側方に逃げた位置との間の被搬送物支持台の運動経路が平面視に於いて吊下搬送用走行体の走行方向に対し略直角の左右横方向であり、しかも当該被搬送物支持台を支持するハンガー側枠から外側へははみ出させないように構成することも可能（許容限度内ではみ出ても良い）であるから、この吊下搬送用ハンガーとの間で被搬送物の受け渡しを行うドロップリフターその他の被搬送物積み降ろし手段側の被搬送物支持部を、例えば実施形態に示したように、前記被搬送物支持台を前後両側及び外側から取り囲むように構成することが出来る。
【００２６】
換言すれば、吊下搬送用ハンガーとの間で被搬送物の受け渡しを行うドロップリフターその他の被搬送物積み降ろし手段側の被搬送物支持部を構成するのに際し、従来のように、当該吊下搬送用ハンガー側の被搬送物支持台の水平旋回や当該被搬送物支持台を支持するハンガー側枠の外側への大きな開動を許すような空間を確保することが困難な部位に於ける吊下搬送用ハンガー側の被搬送物支持台として、本発明に基づく被搬送物支持台を採用することにより、当該被搬送物支持台の周りに前記のような被搬送物支持台の水平旋回や当該被搬送物支持台を支持するハンガー側枠の外側への大きな開動を許すような空間を確保する必要がなくなり、吊下搬送用ハンガーとの間で被搬送物の受け渡しを行うドロップリフターその他の被搬送物積み降ろし手段側の被搬送物支持部の構成が楽になり、ドロップリフターその他の被搬送物積み降ろし手段側での被搬送物支持位置と吊下搬送用ハンガー側での被搬送物支持位置とが大きく離れる不都合を回避し、ドロップリフターその他の被搬送物積み降ろし手段側と吊下搬送用ハンガー側の何れに於いても被搬送物を、支持するのに最も都合の良い部位を利用して安定的且つ安全に支持搬送させることが出来る。
【００２７】
更に、請求項１に記載の本発明によれば、被搬送物支持台が被搬送物を支持しているとき、その負荷を当該被搬送物支持台の内端を昇降駆動する昇降駆動手段側で受け止める必要がない。従って、昇降駆動手段の構成条件が楽になり、簡単且つ安価に構成出来るばかりでなく、安全性も向上する。
【００２８】
又、請求項２や請求項３に記載の本発明によれば、単に被搬送物支持台の強度アップに役立つだけでなく、内端を昇降駆動手段で昇降駆動したときの被搬送物支持台の姿勢切り換えを円滑良好に行わせることが出来る。
【００２９】
更に、請求項４に記載の構成によれば、被搬送物支持台を安定的に支持することが出来ると共に、当該被搬送物支持台の姿勢切り換えも円滑に行わせることが出来る。
【００３０】
又、請求項５に記載の構成によれば、被搬送物支持台の姿勢切り換えのための昇降駆動手段をシリンダーユニットを利用してシンプル且つ安価に構成することが出来、しかも、水平支持姿勢と倒立格納姿勢との間の姿勢切り換え過程で被搬送物支持台がハンガー側枠の外側にはみ出さないように構成することが容易である。

Thus, when the transported object W is loaded on the transported object hanging transport hanger 2 at the point P1 or the point P2, a pair of transported object support bases 7a on the front side of the transported object suspended transport hanger 2 is provided. 7b is turned 90 degrees horizontally around the vertical support shaft to the front outer side to switch to the retracted posture extending forward from the hanger side frames 4a, 4b, and the rear left and right pair of transported object support bases 9a, 9b are In the state where the horizontal support posture H is switched to the inverted retracted posture by the method described above, the suspended conveyance traveling body 1 is stopped at a fixed position at the point P1 or the point P2. Thereafter, the transported object unloading means (not shown) or the drop lifter DL that supports the transported object W is used as the transported object support level of the hanger 2 for transporting the suspended object. Although the level is raised to a higher level, the material unloading means (not shown) at the point P1 or the point P2 or the drop lifter DL and the suspended conveyance traveling body 1 entering the point P1 or the point P2 are covered. When there is no interference with the suspended hanger 2 for transporting the transported object, the transported object stack supporting the transported object W before the suspended transporting traveling body 1 enters the point P1 or the point P2. The lowering means (not shown) or the drop lifter DL can be raised to a level at which the transported object W becomes higher than the transported object support level of the transported object hanging transport hanger 2 and can be kept on standby.
[0019]
When the suspended transporting traveling body 1 arrives at the point P1 or the point P2, the transported object is transported at a height lower than the transported object W supported by the transported object unloading means (not shown) or the drop lifter DL. The pair of transported object support bases 7a and 7b on the front side of the hanger 2 for hanging and transporting the object are rotated 90 degrees horizontally and rearwardly around the vertical support shaft to extend from the hanger side frames 4a and 4b to the inside at right angles. In addition to switching to the supporting posture, the pair of left and right transport object support bases 9a and 9b are switched to the horizontal supporting posture H extending horizontally inward from the hanger side frames 5a and 5b by the method described above. Thereafter, the transported object W supported by the transported object unloading means (not shown) or the drop lifter DL is lowered, and the transported object W is hung 2 on the front side of the hanger 2 for hanging and transporting the transported object. Are transferred onto the supporting jigs 8 and 10 on the left and right pair of transferred object support bases 9a and 9b. When the suspended transport traveling body 1 is run in this state, the transported object suspended transport hanger 2 that supports the transported object W interferes with the transported object unloading means (not shown) or the drop lifter DL. When the object to be transported, the traveling object 1 is unloaded (not shown) or the drop lifter DL is lowered to a level where the interference can be avoided. You can do it.
[0020]
Contrary to the above, when the transported object W is lowered from the transported object hanging transport hanger 2 at the point P1 or the point P2, the suspended transport traveling body 1 is stopped at a fixed position of the point P1 or the point P2. Unloading means for unloading objects such as a table lifter and a running fork that are waiting at a lower level than the objects to be conveyed W supported by the four object support platforms 7a, 7b, 9a, 9b in the support posture ( (Not shown) or the drop lifter DL is raised, and the transferred object W is picked up from the hanger 2 for suspended object transfer by the unloading means (not shown) or the drop lifter DL. When the suspended transport traveling body 1 is run in this state, the transported object unloading means (not shown) or the drop lifter DL and the transported object suspended transport hanger 2 in a state of scooping up the transported object W, The hanger side frame 4a, by turning the pair of left and right front object support bases 7a and 7b horizontally 90 degrees outward and forward around the vertical support shaft. In addition to switching to a retracted posture extending forward from 4b, the pair of rear left and right transported object support bases 9a and 9b are switched from the horizontal support position H to the inverted storage position by the method described above, and these four transported objects In the state where the support bases 7a, 7b, 9a, 9b are displaced to the outside of the transported object W in plan view, the transported object unloading means (not shown) or the drop lifter DL is lowered to support the transported object. Transported object W , Escape from the movement path of the object to be conveyed suspended transport hanger 2 accompanying the traveling of the suspension conveying traveling body 1 downward, after this, it is sufficient to travel the suspended conveying traveling body 1.
[0021]
As described above, the hanger 2 for hanging and conveying the object to be conveyed of the suspended conveyance traveling body 1 can be used, but the rear side of the hanger 2 for hanging and conveying the object to be conveyed in this embodiment. According to the configuration of the pair of left and right transferred object support bases 9a and 9b, for example, a drop lifter DL in which the transferred object W is loaded and unloaded with the transferred object hanging transfer hanger 2 is shown in FIG. 1A. It can be configured as indicated by a solid line and as indicated by a virtual line in FIGS. That is, this type of drop lifter DL is conveyed to a pair of left and right lifting carriages 24a and 24b which are guided by the lifting guide columns 23a and 23b on the left and right sides of the traveling path of the suspended conveying traveling body 1, respectively. Support arms 25a and 25b for supporting the left and right sides of W are provided separately. These support arms 25a and 25b are, for example, transported objects W supported by the transported hanger 2 for transporting suspended objects.

Must be in a position that does not interfere with movement. Of course, these support arms 25a and 25b do not support the object to be transported W at a position far from the support position by the support jigs 8 and 10 of the suspended hanger 2 for transporting the object to be transported. It must be able to support the article W to be transported at a position adjacent to the jigs 8 and 10.
[0022]
Thus, the pair of left and right support jigs 8 on the front side of the hanger 2 for suspending and transporting the object to be transported turn horizontally forward and outward when switching to the retracted position. Are provided with support arms 27a and 27b provided with a supporting jig 26 for supporting the article to be conveyed W at a position adjacent to the rear side of the supporting jig 8 when the article to be conveyed W is supported. Just do it. The pair of left and right support jigs 10 are long in the front-rear direction, but when they are switched to the retracted position, they are moved laterally outward until they overlap with the hanger side frames 5a, 5b in plan view. Therefore, for this support jig 10, a pair of front and rear supports for supporting the object to be conveyed W at positions adjacent to the front and rear sides of the support jig 10 when the object to be conveyed W is supported. A pair of front and rear support arms 30a, 31a and 30b, 31b provided with the jigs 28, 29 can be provided. Further, the lifting carriages 24a, 24b to which the three support arms 27a, 30a, 31a and 27b, 30b, 31b are attached can be arranged so as to be adjacent to the outside of the hanger side frames 5a, 5b.
[0023]
The drop lifter DL in this embodiment is for transporting the transported object W between the suspended transport hanger 2 of the suspended transport traveling body 1 and other transport means below and the like. Therefore, the support arms 27a, 30a, 31a and 27b, 30b, 31b are, as shown in FIG. It is supported so as to be movable in and out horizontally with respect to the lift carriages 24a and 24b.
[0024]
In the above embodiment, since the front side of the left and right sides of the object to be conveyed W only needs to be supported at one place, the conventionally known horizontal swivel type object supports 7a and 7b are used. Similarly, when it is necessary to support at least two front and rear ends of a region having a required length in the front-rear direction, the object support having the same configuration as the pair of rear-side left and right object support bases 9a and 9b is used. A stand can be provided. Further, the hanger side frames 5a and 5b provided with the transported object support bases 9a and 9b do not need to be completely fixed to the suspended transporting traveling body 1, and the drop lifter DL and other transported objects are not required. It is configured to be swingable or slidable in the left and right lateral directions within a range in which interference with the loading / unloading means can be avoided, and the hanger side frames 5a and 5b are moved outward and supported by the lift drive means 12. It is also possible to configure such that the transported object support bases 9a and 9b are switched to the inverted storage posture V in combination with the lifting of the inner ends of 9a and 9b.
[0025]
