Description

【0001】
【発明の属する技術分野】
本発明は、自動車を搬送する搬送台車に関し、特に、車体下部両側を前後2箇所で支持して搬送する台車に関する。
【0002】
【従来の技術】
従来、自動車を搬送する搬送台車として、車体下部両側のサイドシルを台車上に設けた前後方向2箇所の受具で支持して搬送するものが知られている(例えば、特許文献1参照。)。この従来の搬送台車は、受具が車幅方向にスライドするように構成され、受具の車幅方向の間隔を搬送する自動車に合わせて調整することにより、様々な車幅の自動車の搬送に用いることができる。
【0003】
【特許文献1】
特公平6−47411号公報
【0004】
【発明が解決しようとする課題】
しかし、この従来の構造では、車体を支持する受具が、車幅方向にはスライド可能に構成されているものの、前後方向の位置は固定されている。そのため、前後方向2箇所の受具の間隔が大きく設定されている場合には、サイドシル長が短い小型の車体を受具で支持することができず、また、受具の間隔が小さく設定されている場合には、サイドシル長が長い大型の車体を受具で支持する場合に、受具上で車体が不安定になるおそれがある。
【0005】
また、上記従来の構造では、自動車の幅方向中心が台車の幅方向中心に一致するように位置決めされて載置される。そのため、この台車によって搬送された次の工程において、移載装置によって自動車をその幅方向から保持して移載するような場合、移載装置は、搬送されてきた車体の車幅によって、保持手段を車体の両側から移動する距離を変更して制御しなければならず、保持手段の機構が複雑になるとともに、その制御が煩雑になるといった問題がある。
【0006】
そこで本発明は、上記の問題点に鑑み、自動車の車長の長短に関わらず車体を安定して載置することができ、さらに、次工程において車体を移載する場合にも、移載装置が複雑にならず、煩雑な制御を要しない搬送台車を提供することを課題とする。
【0007】
【課題を解決するための手段】
上記課題を解決するために本発明は、車体ワークを搬送する車体搬送台車であって、台車上に設けられた受具で車体下部を支持する車体搬送台車において、前記受具は、車体下部の少なくとも前後左右4箇所を支持する一組の受具群として設けられると共に、該受具群は複数車種の車長及び車幅に対応させて複数組設けられ、該複数組の受具群は、各受具群の車幅方向の左右いずれか一方の受具が車長方向に平行な一直線上に位置するように配設されていることを特徴とする。
【0008】
これによれば、受具群が複数車種の車長に対応させて複数組設けられているので、自動車の車長の長短に関わらず車体を安定して載置することができる。また、複数組の受具群が、各受具群の車幅方向の左右いずれか一方の受具が一直線上に位置するように配設されているので、次工程において車体を移載する場合、移載装置は、搬送されてきた車体の車幅に関わらず、前記一直線上に位置している受具側を基準に、反対側の受具側からのみ、車体の大きさに合わせて車体を保持する保持手段を移動させれば良く、移載装置及びその制御が簡単になる。
【0009】
また、前記受具上面のワーク支持面は鉄板で形成されるのが好ましい。
【0010】
【発明の実施の形態】
図1及び図2を参照して、1は、自動車の車体ワークWを搬送する車体搬送台車を示している。車体搬送台車1は、その上面に、車体ワークWを支持するための受具2を備えている。
【0011】
車体搬送台車1は、車長方向に延びる2本の前後方向桁3と、その前後方向桁3を接続する2本の接続桁4と、前後方向桁3上に渡されて車幅方向に延びる4本の受具用桁5a、5b、5c、5dを備えている。
【0012】
搬送台車1の前部と後部には、それぞれ車輪取付部6が設けられており、この前部・後部の車輪取付部6にそれぞれ、左右に間隔を存して2つの車輪7取り付けられる。
【0013】
前記4本の受具用桁5a、5b、5c、5dのうち、最も前側の受具用桁5aと最も後側の受具用桁5dは、中型・大型車W1用の受具2を設けるための受具用桁5a、5dであり、中型・大型車W1の車幅に対応した長さl1となっている。また、前から2番目の受具用桁5bと3番目の受具用桁5cは、小型車W2用の受具2を設けるための受具用桁5b、5cであり、小型車W2の車幅に対応した長さl2(l2<l1)となっている。
【0014】
中型・大型車W1用の受具用桁5a、5dは、その前後方向の間隔が、一般的な中型・大型車W1のサイドシル長(車長)に対応するように設けられており、また、小型車W2用の受具用桁5b、5cは、その前後方向の間隔が、一般的な小型車W2のサイドシル長に対応するように設けられている。
【0015】
また、受具用桁5a、5b、5c、5dは、その右側(図1において上側)が一直線上に揃うように設けられており、受具用桁5a、5b、5c、5dの両端上には、車体ワークWのサイドシルを支持する受具2がそれぞれ設けられている。これにより、受具用桁5a、5dに設けられた4つの受具2によって、中型・大型車W1用の受具群G1が構成され、受具用桁5b、5cに設けられた4つの受具2によって、小型車W2用の受具群G2が構成される。そして、各受具群G1、G2の車幅方向右側の受具2が一直線上に位置している。
【0016】
各受具2は、その上面のワーク支持面が鉄製の縞綱板で形成されている。ここで、縞綱板の摩擦係数が過大であると、車体ワークWを後述する姿勢変更装置8で把持する場合に、受具2上の車体ワークWが殆どスライドせず、姿勢変更装置8に過大な負荷がかかると共に、車体ワークWと受具2との摩擦により大きな音が発生してしまう。また、縞綱板の摩擦係数が過小であると、受具2上に支持された車体ワークWが搬送中等にズレて落下してしまうおそれがある。そこで、縞綱板の凹凸は最適な摩擦係数となるように構成されており、これにより、受具2上に支持された車体ワークWは搬送中には受具2上でずれることがなく、また、姿勢変更装置8等で強い力を作用させたときには受具2上でスライドし、受具2上の車体ワークWの微小な位置ズレは、姿勢変更装置8等からの作用力により修正されることになる。
【0017】
また、前記接続桁4の下部には、車体搬送台車1を牽引するための牽引座9が設けられている。
【0018】
次に、本実施形態の作用について説明する。
【0019】
車体搬送台車1によって中型・大型車W1を搬送する場合、中型・大型車W1の車体下部両側のサイドシルが、受具用桁5a、5dに設けられた4つの受具2上に支持されるように載置される。また、小型車W2を搬送する場合、小型車W2の車体下部両側のサイドシルが、受具用桁5b、5cに設けられた4つの受具2上に支持されるように載置される。
【0020】
この状態で、車体搬送台車1が牽引座9を介して牽引され、次工程のステーションSへと搬送される。本実施形態では、次工程のステーションSには車体ワークWの姿勢を反転させる姿勢変更装置8が設置されている。
【0021】
姿勢変更装置8は、支柱81に沿って昇降する支持体82を備えており、この支持体82には、車体ワークWを車幅方向に跨ぐようにして保持する車体保持フレーム83が設けられている。該車体保持フレーム83は、支持体83に対して車長方向の軸線回りに回動自在に構成されており、車体保持フレーム84の図3で時計方向への回動により、車体ワークWを横転姿勢に姿勢変更し、車体下回りの解体作業を作業性良く行い得られるようにしている。車体保持フレーム83には、その中央部に位置させて車体ワークWのルーフを押圧するルーフ押圧部材84が設けられており、更に、車体保持フレーム83の車幅方向両側部に位置させて、車幅方向内方に進退自在な1対の把持部材85、86が設けられている。 各把持部材85、86は、車幅方向内方に開口する略コ字状に形成されており、その下側部を、車体ワークWのサイドシルを下方から受ける受座部85a、86aに構成し、その上側部をサイドシルに車幅方向外方から当接する爪部85b、86bに構成している。受座部85a、86aは、爪部85b、86bより長く、且つ、先端が車幅方向内方に向って下方に傾斜しており、把持部材85、86を車幅方向内方に前進させたとき、サイドシルの下面に受座部85a、86aがせり込み、サイドシルが受座部85a、86aによって下方から支持されるようにしている。把持部材85、86の車幅方向への移動で爪部85b、86bがサイドシルの外側面の上縁部に当接し、サイドシルに車幅方向内方への押付力と下方への押付力とが作用するようにしている。かくて、車体ワークWは把持部材85、86によって車幅方向及び車高方向に確実に拘束される。
【0022】
車体搬送台車1は、姿勢変更装置8に対して、車体ワークWをその車体右側が支柱81側に向けた状態で搬入するようにしている。このとき、車体搬送台車1は常に同じ位置に搬入される。
【0023】
姿勢変更装置8位置に車体ワークWが載置された車体搬送台車1が搬送されると、姿勢変更装置8の2つの把持部材85、86が車幅方向内方に移動する。このとき、車体左側の把持部材85は、搬送されてきた車体の大きさに応じて入力された移動距離だけ移動し、車体右側の把持部材86は、搬送されてきた車体の大きさに関わらず予め設定されている所定距離だけ移動する。
【0024】
把持部材85、86が移動すると、車体ワークWのサイドシルの下面に把持部材85、86の受座部85a、86aがせり込み、サイドシルが受座部85a、86aによって下方から支持される。さらに把持部材85、86が移動すると、把持部材85、86の爪部85b、86bがサイドシルの外側面の上縁部に当接し、サイドシルに車幅方向内方への押付力と下方への押付力とが作用する。これにより車体ワークWが両側から把持され、その後、ルーフ押圧部材84により車体ワークWのルーフを押圧してから、支持体82により車体保持フレーム83を上昇させて車体ワークWを車体搬送台車1から持ち上げる。そして、車体搬送台車1を退去させた後、車体保持フレーム83を回動して車体ワークWを横転姿勢にし、車体下回りの解体作業を行う。
【0025】
なお、本発明は前記実施形態のものに限定されるものではなく、必要に応じて種々変更することが可能である。
【0026】
【発明の効果】
以上の説明から明らかなように、本発明は、受具群が複数車種の車長に対応させて複数組設けられているので、自動車の車長の長短に関わらず車体を安定して載置することができる。また、複数組の受具群が、各受具群の車幅方向の左右いずれか一方の受具が一直線上に位置するように配設されているので、次工程において車体を移載する場合、移載装置は、搬送されてきた車体の車幅に関わらず、前記一直線上に位置している受具側を基準に、反対側の受具側からのみ、車体の大きさに合わせて車体を保持する保持手段を移動させれば良く、移載装置及びその制御が簡単になる。
