Description

【０００１】
【発明の属する技術分野】
本発明は布線機に関し、特に、電線配索部材上に配置された複数個の電線圧入リブに電線を挟持させることで、所定形状の導体回路を形成する布線機の改良に関するものである。
【０００２】
【従来の技術】
電線配索部材１は、図１２に示すように、所望形状の支持基材２上の電線の配索経路に沿って適宜間隔で突設される複数個の電線圧入リブ３を、絶縁性樹脂等によって一体成形したものである。
前記電線圧入リブ３は、電線を押し込み可能な直線的な電線挟持溝３ａを一対の対向壁３ｂ，３ｂによって形成した構成を成している。
【０００３】
そして、このような電線配索部材１は、図１３に示すように、電線の配索経路に沿う並び順に従って各電線圧入リブ３の電線挟持溝３ａに電線５を挟持させていくことにより、複数個の電線圧入リブ３を順に経由する導体回路６が形成される。
このように形成された導体回路６は、例えば、特開平６−２７５１１７号公報等にも開示されているように、車両用のコンビネーションランプ内の電球に給電するための導体回路、あるいは、車両用の電気接続箱内においてバスバー等に接続する導体回路として利用される。
【０００４】
ところで、車両用の部品は省力化のための自動化が盛んで、前記電線配索部材１への電線５の配索作業も、図１４に示すような布線機を使用した自動化が図られている。
ここに示した布線機は、図１４（ａ）に示すように、図示せぬヘッド移動手段に取付けられて電線配索部材１上の任意方向に移動可能な布線ヘッド７が、電線送給手段の下端部に設けられて電線５を送出する電線ノズル７ａと、該電線ノズル７ａの進行方向下流側に配置され、送出された電線５を前記電線挟持溝３ａ内に圧入するべく上下動可能な圧入刃７ｂとを備えている。
そして、前記布線ヘッド７の移動操作で電線５を前記電線挟持溝３ａの上に添わせた状態にした後、図１４（ｂ）に示すように、圧入刃７ｂで電線５を電線挟持溝３ａ内に押し込むことで、電線挟持溝３ａに電線５を挟持させる。
【０００５】
【発明が解決しようとする課題】
ところで、図１５に示すように、支持基材２上の配索順に隣接した電線圧入リブ３，３の設置方向が異なる場合は、配索経路の上流側に位置する電線圧入リブ３の電線挟持溝３ａの電線出口３ｃが配索経路下流側の電線圧入リブ３の電線挟持溝３ａの延在方向Ｌから外れてしまう。
【０００６】
このような設置向きが異なる電線圧入リブ３，３間では、上述の如き布線機を用いて、上流側の電線圧入リブ３の電線挟持溝３ａの出口３ｃから下流側の電線圧入リブ３の電線挟持溝３ａの出口まで電線５を誘導すると、図１６に示すように、電線５が一方の対向壁３ｂの上端面上を斜めに横切る状態となる虞がある。
【０００７】
そして、このように電線５が一方の対向壁３ｂの上端面上を斜めに横切って前記電線挟持溝３ａにうまく添わせられないと、圧入刃７ｂによる電線５の押し込みが困難になったり、あるいは電線５の破断等の事故を招く可能性があり、電線配索の自動化に対する大きな障害となっていた。
従って、本発明の目的は上記課題を解消することにあり、電線配索部材上に配置された複数個の電線圧入リブの電線挟持溝に電線を挟持させることによって、所定形状の導体回路を電線配索部材に形成する配索作業の自動化を容易にすることができる良好な布線機を提供することである。
【０００８】
【課題を解決するための手段】
本発明の上記目的は、布線ヘッドの電線送給手段から送出された電線を電線配索部材上に配設された複数個の電線圧入リブの電線挟持溝内に順次押し込んで導体回路を形成する布線機であって、
ヘッド移動手段に取付けられて移動可能な前記布線ヘッドが、前記電線送給手段の下端部に設けられて電線を送出する電線送出部と、該電線送出部の進行方向下流側に配置され、送出された電線を前記電線挟持溝内に圧入するべく上下動可能な圧入刃と、該圧入刃を両面から挟装するようにして圧入刃進退方向に延設され、前記電線送出部から送出された電線を挿通可能な案内溝が形成された電線ガイド部とを備えており、
前記圧入刃が前進して前記電線を電線挟持溝内に押し込む際には、該電線が前記電線ガイド部によって前記電線挟持溝の延在方向に案内され、
前記ヘッド移動手段が、前記電線ガイド部における案内溝の下流端からさらに下流側に離間した位置を通るとき、下流端に位置する電線圧入リブの電線挟持溝の布線方向の出口でさらに下流に位置する電線圧入リブの電線挟持溝の布線方向の入口に向けて前記布線ヘッドを旋回させ、また、当該下流に位置する電線圧入リブの電線挟持溝の入口で当該電線圧入リブの電線挟持溝の軸線に合致するまで布線ヘッドを旋回させて移動方向を変えるこことを特徴とする布線機により達成される。
【０００９】
上記構成の布線機によれば、布線ヘッドが電線圧入リブ間を順次移動する際には、電線送出部から送り出された電線が電線ガイド部の案内溝に挿通され、該電線は少なくとも該案内溝に挿通される部分での送出方向が規制される。
そこで、布線ヘッドが次の圧入対象の電線圧入リブ上に誘導される際には、前記電線の送出方向を決定している前記電線ガイド部の案内溝が、圧入対象の電線圧入リブの電線挟持溝の延在方向に一致するように、該布線ヘッドを移動させる。
【００１０】
そして、前記電線ガイド部の案内溝の向きが電線圧入リブの電線挟持溝の延在方向に一致したら、布線ヘッドをそのまま降下させて、前記案内溝が前記電線挟持溝に略連通した状態にする。
この状態では、圧入対象の電線圧入リブより上流側に位置する電線圧入リブの電線挟持溝の電線出口が、該圧入対象の電線圧入リブの電線挟持溝の延在方向から外れている場合でも、圧入刃に押し込まれる部分の電線は、電線ガイド部の案内溝によって送出方向が電線挟持溝に添う直線状態に矯正され、正確に電線挟持溝に添った状態に支持される。
そこで、この状態で圧入刃を前進させて電線挟持溝の上に沿った状態にある電線を電線挟持溝内に押し込めば、確実に圧入が行える。
【００１１】
従って、布線ヘッドが誘導した電線が圧入対象の電線圧入リブの電線挟持溝を形成している対向壁の上端縁を横切ることがなくなるので、各電線圧入リブへの電線の圧入作業を確実に実施でき、所定形状の導体回路を電線配索部材に形成する布線機による配索作業の自動化を容易にすることができる。
【００１２】
また、本発明においては、前記ヘッド移動手段が、前記電線ガイド部における案内溝の下流端からさらに下流側に離間した位置を通る軸線を回転中心として前記布線ヘッドを旋回させることにより移動方向を変える。この場合、布線ヘッドが電線圧入リブへの電線の圧入を済ませた後は、電線ガイド部における案内溝の下流端が前記電線圧入リブの電線挟持溝を通過するまで該布線ヘッドを移動させてから旋回させ、布線ヘッドの移動方向を変える。これにより、下流側の電線圧入リブに向かって布線ヘッドを大きく旋回させても、案内溝に挿通されている電線に対して電線ガイド部が過大な張力を付与することはなく、上流側の電線圧入リブに圧入された電線の脱落や案内溝に挿通された電線の外れを招く虞が無い。好ましくは、前記案内溝の下流端からの前記回転中心の軸線の離間寸法が、圧入を済ませた電線圧入リブの近くで前記布線ヘッドを旋回操作した際に、電線の曲げに支障が生じない程度で必要最小限に設定される。
【００１３】
又、布線ヘッドが次の圧入対象の電線圧入リブ上に誘導された後、前記電線ガイド部の案内溝が圧入対象の電線圧入リブの電線挟持溝の延在方向に一致するように該布線ヘッドを大きく旋回させる際は、電線ガイド部における案内溝の下流端が前記電線挟持溝の延在方向に一致するまで該布線ヘッドを移動させてから旋回させる。これにより、電線挟持溝の延在方向に一致するまで該布線ヘッドを大きく旋回させても、案内溝に挿通されている電線に対して電線ガイド部が過大な張力を付与することはなく、案内溝に挿通されている電線が外れて電線挟持溝に添った状態に支持されなくなることは無い。
【００１４】
【発明の実施の形態】
以下、添付図面に基づいて本発明の一実施形態に係る布線機を詳細に説明する。
図１及び図２は本発明の一実施形態に係る布線機の部分断面側面図及び正面図、図３は図１に示した布線ヘッドの要部拡大断面図、図４は図３に示した布線ヘッドの正面図、図５乃至図７は図１に示した布線ヘッドの動作を説明する部分断面側面図及び要部拡大図、図８及び図９は図１に示した布線ヘッドの動作を説明する水平断面図、図１０及び図１１は図１に示した布線ヘッドの配索面の他の形態に応じた具体的な操作手順を説明する要部拡大図である。
【００１５】
本実施形態の布線機１１は、図１及び図２に示すように、図示しないヘッド移動手段に取付けられて三次元方向に移動可能な布線ヘッド１７によって、例えば図１２に示したような電線配索部材１上の複数個の電線圧入リブ３に順に電線５を挟持させていくことにより、所定の導体回路６を形成するものである。
前記布線ヘッド１７は、電線送給手段２１の下端部に設けられて電線５を送出する電線送出部である電線ノズル１３と、該電線ノズル１３の進行方向下流側（図１中、右側）に配置され、送出された電線５を電線圧入リブ３の電線挟持溝３ａ内に圧入するべく上下動可能な圧入刃１５と、該圧入刃１５を両面から挟装するようにして圧入刃進退方向に延設され、前記電線ノズル１３から送出された電線５を挿通可能な案内溝２７が形成された電線ガイド部２５と、前記電線ノズル１３から送出された電線５を所定の長さで切断する電線カッタ２３とを備えている。
【００１６】
尚、前記ヘッド移動手段としては、布線ヘッド１７を互いに直交するＸ軸、Ｙ軸、Ｚ軸の３軸方向に任意量移動させることのできる公知の３軸移動機構が利用可能である。そして、前記ヘッド移動手段は、前記電線ガイド部２５における案内溝２７の下流端近傍を通る軸線１９を回転中心として前記布線ヘッド１７を旋回させることもできる。
ここで、前記案内溝２７の下流端からの前記軸線１９の離間寸法は、圧入を済ませた電線圧入リブ３の近くで前記布線ヘッド１７を旋回操作した際に、電線５の曲げに支障が生じない程度で必要最小限に設定すればよい。
【００１７】
前記電線供給手段２１は、図示せぬドラムから供給されて電線送給筒２９に導入案内された電線５を挟持する駆動ローラ３１とニップローラ３２とを備えている。
前記駆動ローラ３１は、歯車機構３４を介して電動モータ３５により回転駆動される。また、前記ニップローラ３２は、エアシリンダ３６及びリンク３７を介して、前記駆動ローラ３１との挟持間隔を調節可能とされている。
【００１８】
そこで、前記電線供給手段２１は、前記電動モータ３５を回転駆動制御することによって、任意の速度で前記電線５を送り出すことができる。又、これら駆動ローラ３１とニップローラ３２の挟持間隔を所定以上に広げることで、電線５に対する挟持を解除でき、前記電線ノズル１３から送り出した電線５に作用する張力等によって該電線５を引き出し自在にできる。
【００１９】
前記布線ヘッド１７における圧入刃１５の近傍に固定された電線ガイド部２５は、図３及び図４に示したように、圧入刃１５の両面側から圧入刃進退方向に沿って下方へ延設された一対の壁部２５ａ，２５ａにより、前記電線ノズル１３から送出された電線５を前記電線挟持溝３ａの長さ分相当以上に渡って該電線挟持溝３ａの延在方向に沿って位置決めする案内溝２７が形成されている。
【００２０】
前記圧入刃１５は、図３に示すように、中間部に前記電線挟持溝３ａの長さ分相当幅の切欠１５ａを有しており、該切欠１５ａの両側の２つの突出部１５ｂ，１５ｂを電線５に押し当てて、該電線５を電線圧入リブ３の電線挟持溝３ａに押し込む。
そこで、前記圧入刃１５が前進して前記電線５を電線挟持溝３ａ内に押し込む際、少なくとも電線挟持溝３ａ内に押し込まれる部分の電線５は、前記電線ガイド部２５の案内溝２７によって前記電線挟持溝３ａの延在方向に確実に案内される。
【００２１】
そして、前記布線機１１は、前記電線ノズル１３から送出された電線５が電線配索部材１上に配置された電線圧入リブ３の電線挟持溝３ａの上を通過するように布線ヘッド部１７を移動させるヘッド移動工程と、該ヘッド移動工程によって前記電線挟持溝３ａ上に横たえられた電線５を圧入刃１５によって電線挟持溝３ａ内に押し込む電線押し込み工程とを繰り返すことで、電線配索部材１上に配置された複数個の電線圧入リブ３を経由した導体回路を形成する。
【００２２】
そこで先ず、上記布線機１１が配索処理を開始する作業開始時には、電線送給筒２９に導入案内された電線５を電線ノズル１３に挿通する。この時、ニップローラ３２を駆動ローラ３１に対して開いた状態とすることにより、電線５は自由にニップローラ３２と駆動ローラ３１との間を挿通することができる。
そして、これらニップローラ３２及び駆動ローラ３１を閉じ、電動モータ３５による回転駆動量に応じて所定長の電線５を送り出し可能な挟持状態にする。更に、前記電線ノズル１３の上方に配置された電線カッタ２３を駆動シリンダ２４によって駆動することで、電線ノズル１３から送出した電線端を切り落として、該電線５の端部をカッタ位置に切り揃えた状態にする。以上の準備作業が完了すれば、配索処理が開始可能になる。
【００２３】
以下、上記布線機１１の配索処理における布線ヘッド１７の動作を説明する。
先ず、ヘッド移動工程においては、図示しないヘッド移動手段によって、前記布線ヘッド１７を目的の電線圧入リブ３上に移動させる（図１、参照）。この時、電線５は前記電線供給手段２１によって、布線ヘッド１７の移動距離に応じた長さを測長しながら送り出される。
【００２４】
又、前記布線ヘッド１７が電線圧入リブ３，３間を順次移動する際には、電線ノズル１３から送り出された電線５が電線ガイド部２５の案内溝２７に挿通され、該電線５は少なくとも該案内溝２７に挿通される部分での送出方向が規制される。
そこで、前記布線ヘッド１７が次の圧入対象の電線圧入リブ３上に誘導される際には、前記電線５の送出方向を決定している前記電線ガイド部２５の案内溝２７の向きが、圧入対象の電線圧入リブ３の電線挟持溝３ａの延在方向に一致するように、該布線ヘッド２５を移動させると共もに軸線１９回りに旋回動作させ、電線ガイド部２５の向きを調整する
【００２５】
そして、前記電線ガイド部２５の案内溝２７の向きが電線圧入リブ３の電線挟持溝３ａの延在方向に一致したら、図５に示したように、前記布線ヘッド１７をそのまま降下させて、電線ガイド部２５の一対の壁部２５ａ，２５ａの下端を電線圧入リブ３の一対の対向壁３ｂ，３ｂの上端面上に近接させる（図６（ａ）参照）。即ち、電線ガイド部２５の案内溝２７と電線圧入リブ３の電線挟持溝３ａとが対向して、略連通した状態と成るようにする。
【００２６】
次に、電線押し込み工程においては、図６（ａ）に示したように、電線ガイド部２５の案内溝２７を電線圧入リブ３の電線挟持溝３ａ上に位置決めすることによって、該電線挟持溝３ａ上に電線５を位置決めした後、圧入刃駆動シリンダ３３により圧入刃１５を前進させることで、図６（ｂ）に示すように、前記電線ガイド部２５によって電線挟持溝３ａの延在方向に案内しながら前記電線５を該電線挟持溝３ａ内に押し込む。
【００２７】
また、圧入時に前記電線５に一定以上の張力がかかる可能性がある場合には、予め、前記電線供給手段２１の駆動ローラ３１とニップローラ３２の挟持間隔を所定以上に広げておく。
そして、電線５の圧入が完了したら、図６（ｃ）に示すように、圧入刃１５を初期位置に戻すと共に、次の電線圧入リブ３への誘導のために駆動ローラ３１とニップローラ３２とで電線５を挟持させた状態にする。
次に、前記電線ガイド部２５における案内溝２７の下流端が、圧入を済ませた電線圧入リブ３の電線挟持溝３ａから外れるまで、該電線挟持溝３ａに沿って布線ヘッド１７を前進させた後、該布線ヘッド１７を所定量下げることで、電線５を前記案内溝２７内に確実に挿通させる。
【００２８】
そして、前記電線供給手段２１により、布線ヘッド１７の移動距離に応じた長さの電線５を送り出しながら、再び図示しないヘッド移動手段によって、図７に示すように、前記布線ヘッド１７を次の目的の電線圧入リブ３上に移動させる。
以上のヘッド移動工程及び押し込み工程を繰り返すことで、所定の導体回路が前記電線配索部材１上に配置される。そして、電線カッタ２３を駆動シリンダ２４によって駆動することで、電線ノズル１３から送出した電線端を切断して所定の導体回路の配索が完了する。
【００２９】
従って、本実施形態の布線機１１によれば、布線ヘッド１７が誘導した電線５が圧入対象の電線圧入リブ３の電線挟持溝３ａを形成している対向壁３ｂ，３ｂの上端縁を横切ることがなくなる。
そこで、各電線圧入リブ３への電線５の圧入作業を確実に実施でき、所定形状の導体回路を電線配索部材１に形成する布線機１１による配索作業の自動化を容易にすることができる。
【００３０】
次に、図８（ａ）に示したように、圧入対象の電線圧入リブ３より上流側に位置する電線圧入リブ３の電線挟持溝３ａの電線出口３ｃが、該圧入対象の電線圧入リブ３の電線挟持溝３ａの延在方向Ｌから外れている場合の配索処理における布線ヘッド１７の動作を説明する。
先ず、図８（ａ）に示すように、押し込み工程を実施することで、上流側の電線圧入リブ３の電線挟持溝３ａに対する電線５の圧入を完了させる。
【００３１】
次に、図８（ｂ）に示すように、前記布線ヘッド１７を旋回させる際の回転中心として前記電線ガイド部２５における案内溝２７の下流端近傍に設定した軸線１９が、圧入を済ませた電線圧入リブ３の電線挟持溝３ａから外れるまで、該電線挟持溝３ａに沿って布線ヘッド１７を前進させる。その後、該布線ヘッド１７を所定量下げることで、電線５を前記案内溝２７内に確実に挿通させる。
次いで、図８（ｃ）に示すように、前記布線ヘッド１７が下流の圧入対象の電線圧入リブ３の電線挟持溝３ａの電線入口に向くまで、軸線１９を中心に該布線ヘッド１７を旋回させる。
【００３２】
この様に、下流側の電線圧入リブ３に向かって布線ヘッド１７を移動させる際、前記電線ガイド部２５における案内溝２７の下流端近傍に設定した軸線１９を回転中心として前記布線ヘッド１７を旋回させれば、前記電線ガイド部２５の案内溝２７に挿通されている電線５に対して電線ガイド部２５が過大な張力を付与することはなく、上流側の電線圧入リブ３に圧入された電線５の脱落や案内溝２７に挿通された電線５の外れを招く虞が無い。
【００３３】
尚、布線ヘッド１７を大きく旋回させねばならず、上流の電線５が引っ張られる虞がある場合には、駆動ローラ３１とニップローラ３２による電線５の挟持を解除したり、必要に応じて電線供給手段２１による電線５の送り出しを実施することによって、該電線５に対して所定以上の張力が作用するのを防止することもできる。
【００３４】
そして、図９（ａ）に示すように、前記軸線１９が下流の圧入対象の電線圧入リブ３の電線挟持溝３ａの電線入口の直前に位置するまで、布線ヘッド１７が誘導される
次いで、電線圧入リブ３上に位置している布線ヘッド１７を、軸線１９回りに旋回動作させて、図９（ｂ）に示すように、前記電線ガイド部２５の案内溝２７の向きが電線圧入リブ３の電線挟持溝３ａの延在方向に一致するように調整する。
【００３５】
この際、前記電線ガイド部２５の案内溝２７が圧入対象の電線圧入リブ３の電線挟持溝３ａの延在方向Ｌに一致するように前記布線ヘッド１７を旋回させても、前記軸線１９を回転中心として該布線ヘッド１７を旋回させれば、前記案内溝２７に挿通されている電線５に対して電線ガイド部２５が過大な張力を付与することはなく、案内溝２７に挿通されている電線５が外れて電線挟持溝３ａに添った状態に支持されなくなることは無い。勿論、駆動ローラ３１とニップローラ３２による電線５の挟持を解除したり、必要に応じて電線供給手段２１による電線５の送り出しを実施することによって、該電線５に対して所定以上の張力が作用するのを防止することもできる。
【００３６】
そして、前記電線ガイド部２５の案内溝２７の向きが電線圧入リブ３の電線挟持溝３ａの延在方向に一致したら、前記布線ヘッド１７をそのまま降下させて、電線ガイド部２５の一対の壁部２５ａ，２５ａの下端を電線圧入リブ３の一対の対向壁３ｂ，３ｂの上端面上に近接させる（図６（ａ）参照）。
【００３７】
すると、図８及び図９に示したように、圧入対象の電線圧入リブ３より上流側に位置する電線圧入リブ３の電線挟持溝３ａの電線出口３ｃが、該圧入対象の電線圧入リブ３の電線挟持溝３ａの延在方向Ｌから外れている場合でも、圧入刃１５に押し込まれる部分の電線５は、電線ガイド部２５の案内溝２７によって送出方向が電線挟持溝３ａに添う直線状態に矯正され、正確に電線挟持溝３ａに添った状態に支持される。
そこで、この状態で圧入刃１５を前進させて電線挟持溝３ａの上に沿った状態にある電線５を前記案内溝２７で案内しながら該電線挟持溝３ａ内に押し込めば、確実に電線５の圧入が行える。
【００３８】
即ち、本実施形態の布線機１１では、電線ノズル１３から送り出された電線５の向きや位置は、布線ヘッド１７に設けた電線ガイド部２５によって電線圧入リブ３の電線挟持溝３ａに沿って直線上に矯正され、該布線ヘッド１７の旋回動作によって正確に電線圧入リブ３の電線挟持溝３ａ上に位置決めすることができる。
従って、設置向きが異なる電線圧入リブ３，３間に電線５を配索する場合でも、誘導した電線５が電線圧入リブ３の一対の対向壁３ｂ，３ｂの上端縁を横切ることがなくなり、各電線圧入リブ３，３への圧入作業を確実に実施できて、電線５の配索作業の自動化を容易にすることができる。
【００３９】
更に、本実施形態の布線機１１は、布線ヘッド１７が旋回する際に電線圧入リブ３に圧入済の電線５が脱落するを防止する為の従来の布線機のような電線の余分な送り出し操作や、布線ヘッド１７を電線圧入リブ３から大きく退避させる移動操作が必要なくなる。そこで、本実施形態の布線機１１は、最短経路での配索が可能となり、従来の布線機に比べて配索工程を減少させ、作業効率の向上を図ることができる。
【００４０】
次に、図１０に示したように、電線圧入リブ３の設置面２０が傾斜面である時は、布線ヘッド１７の水平移動時に電線５に必要以上の張力が作用して、電線圧入リブ３に圧入済の電線５が脱落する虞がある。
そこで、下流の電線圧入リブ３に向かって布線ヘッド１７を水平移動する前に、前記電線供給手段２１による電線５の送り出しを実施して適当な余長を付与したり、あるいは駆動ローラ３１とニップローラ３２による電線５の挟持を解除すれば、必要以上の張力が電線５に作用することはなく、良好な配索が可能となる。
【００４１】
更に、図１１に示したように、電線配索部材上に配置された二つの電線圧入リブ３，３が、高低差の大きな設置面２０ａ，２０ｂにそれぞれ設けられている場合の配索処理における布線ヘッド１７の動作を説明する。
先ず、図１１（ａ）に示すように、押し込み工程を実施することで、設置面２０ａに突設された上流側の電線圧入リブ３の電線挟持溝３ａに対する電線５の圧入を完了させる。
【００４２】
次に、図１１（ｂ）に示すように、前記電線供給手段２１により、布線ヘッド１７の移動距離に応じた長さの電線５を送り出しながら、該布線ヘッド１７を水平移動させ、ガイド部２５を設置面２０ｂに突設された次の目的の電線圧入リブ３の鉛直線上に移動させる。
その後、図１１（ｃ）に示すように、電線５を前記案内溝２７内に挿通させた状態で、前記布線ヘッド１７を下降させる。この際、上流の電線５が案内溝２７の下流端縁に接触したり、該案内溝２７から外れたりすることがないように、前記電線供給手段２１により電線５の送り出し制御が適宜行なわれる。
【００４３】
次に、図１１（ｄ）に示すように、前記電線ガイド部２５の案内溝２７の向きが電線圧入リブ３の電線挟持溝３ａの延在方向に一致するように位置決めして、電線ガイド部２５の下端を電線圧入リブ３の上端面上に近接させる。
そして、電線押し込み工程においては、図１１（ｅ）に示すように、圧入刃１５を前進させることで、電線５を案内溝２７によって電線挟持溝３ａの延在方向に案内しながら該電線挟持溝３ａ内に押し込むことができる。
【００４４】
従って、電線配索部材上に配置された二つの電線圧入リブ３，３が、高低差の大きな設置面２０ａ，２０ｂにそれぞれ設けられている場合でも、誘導した電線５が下流側の電線圧入リブ３の一対の対向壁３ｂ，３ｂの上端縁を横切ることがなくなり、各電線圧入リブ３，３への圧入作業を確実に実施できて、電線５の配索作業の自動化を容易にすることができる。
【００４５】
尚、本発明の布線機における布線ヘッド、電線送給手段、電線送出部、圧入刃及び電線ガイド部等の構成は、上記実施形態の構成に限定されるものではなく、本発明の趣旨に基づいて種々の形態を採りうることは云うまでもない。

本発明の布線機によれば、布線ヘッドが電線圧入リブ間を順次移動する際には、電線送出部から送り出された電線が電線ガイド部の案内溝に挿通され、該電線は少なくとも該案内溝に挿通される部分での送出方向が規制される。
そこで、布線ヘッドが次の圧入対象の電線圧入リブ上に誘導される際には、前記電線の送出方向を決定している前記電線ガイド部の案内溝が、圧入対象の電線圧入リブの電線挟持溝の延在方向に一致するように、該布線ヘッドを移動させる。
【００４７】
そして、前記電線ガイド部の案内溝の向きが電線圧入リブの電線挟持溝の延在方向に一致したら、布線ヘッドをそのまま降下させて、前記案内溝が前記電線挟持溝に略連通した状態にする。
この状態では、圧入対象の電線圧入リブより上流側に位置する電線圧入リブの電線挟持溝の電線出口が、該圧入対象の電線圧入リブの電線挟持溝の延在方向から外れている場合でも、圧入刃に押し込まれる部分の電線は、電線ガイド部の案内溝によって送出方向が電線挟持溝に添う直線状態に矯正され、正確に電線挟持溝に添った状態に支持される。
【００４８】
そこで、この状態で圧入刃を前進させて電線挟持溝の上に沿った状態にある電線を電線挟持溝内に押し込めば、確実に圧入が行える。従って、布線ヘッドが誘導した電線が圧入対象の電線圧入リブの電線挟持溝を形成している対向壁の上端縁を横切ることがなくなるので、各電線圧入リブへの電線の圧入作業を確実に実施でき、所定形状の導体回路を電線配索部材に形成する布線機による配索作業の自動化を容易にすることができる。
また、本発明の布線機によれば、前記ヘッド移動手段が、前記電線ガイド部における案内溝の下流端からさらに下流側に離間した位置を通る軸線を回転中心として前記布線ヘッドを旋回させることにより移動方向を変える。この場合、布線ヘッドが電線圧入リブへの電線の圧入を済ませた後は、電線ガイド部における案内溝の下流端が前記電線圧入リブの電線挟持溝を通過するまで該布線ヘッドを移動させてから旋回させ、布線ヘッドの移動方向を変える。これにより、下流側の電線圧入リブに向かって布線ヘッドを大きく旋回させても、案内溝に挿通されている電線に対して電線ガイド部が過大な張力を付与することはなく、上流側の電線圧入リブに圧入された電線の脱落や案内溝に挿通された電線の外れを招く虞が無い。

BACKGROUND OF THE INVENTION
The present invention relates to a wiring machine, and more particularly to an improvement of a wiring machine that forms a conductor circuit of a predetermined shape by sandwiching an electric wire between a plurality of electric wire press-fitting ribs arranged on an electric wire routing member. .
[0002]
[Prior art]
As shown in FIG. 12, the wire routing member 1 includes a plurality of wire press-fitting ribs 3 protruding at appropriate intervals along the wire routing route on the support base 2 having a desired shape. Etc., which are integrally molded.
The wire press-fitting rib 3 has a configuration in which a linear wire holding groove 3a into which a wire can be pushed is formed by a pair of opposing walls 3b and 3b.
[0003]
And as shown in FIG. 13, such an electric wire routing member 1 clamps the electric wire 5 in the electric wire clamping groove 3a of each electric wire press-fitting rib 3 according to the arrangement order along the electric wire routing path, A conductor circuit 6 is formed through the plurality of wire press-fitting ribs 3 in order.
The conductor circuit 6 formed in this way is, for example, a conductor circuit for supplying power to a light bulb in a combination lamp for a vehicle, as disclosed in JP-A-6-275117, etc. This is used as a conductor circuit connected to a bus bar or the like in the electrical junction box.
[0004]
By the way, automation for labor saving is prosperous in the parts for vehicles, and the wiring work of the electric wire 5 to the electric wire wiring member 1 is also automated using a wiring machine as shown in FIG. Yes.
In the wiring machine shown here, as shown in FIG. 14 (a), the wiring head 7 attached to the head moving means (not shown) and movable in an arbitrary direction on the wire routing member 1 An electric wire nozzle 7a that is provided at the lower end of the feeding means and sends out the electric wire 5, and is arranged on the downstream side in the traveling direction of the electric wire nozzle 7a, and moves up and down to press-fit the sent electric wire 5 into the electric wire holding groove 3a. A press-fitting blade 7b is provided.
Then, after the electric wire 5 is put on the electric wire holding groove 3a by the moving operation of the wiring head 7, as shown in FIG. 14 (b), the electric wire 5 is inserted into the electric wire holding groove by the press-fitting blade 7b. The electric wire 5 is clamped in the electric wire clamping groove 3a by pushing into 3a.
[0005]
[Problems to be solved by the invention]
By the way, as shown in FIG. 15, when the installation directions of the wire press-fitting ribs 3 and 3 adjacent to each other in the wiring order on the support base 2 are different, the electric wire is clamped by the wire press-fitting ribs 3 positioned on the upstream side of the wiring path. The wire outlet 3c of the groove 3a deviates from the extending direction L of the wire holding groove 3a of the wire press-fitting rib 3 on the downstream side of the wiring path.
[0006]
Between the wire press-fitting ribs 3 and 3 having different installation directions, the wire press-fitting rib 3 on the downstream side from the outlet 3c of the wire clamping groove 3a of the wire press-fitting rib 3 on the upstream side is used by using the wiring machine as described above. When the electric wire 5 is guided to the outlet of the electric wire holding groove 3a, as shown in FIG. 16, there is a possibility that the electric wire 5 may obliquely cross the upper end surface of the one opposing wall 3b.
[0007]
If the electric wire 5 does not cross the upper end surface of the one opposing wall 3b diagonally and is not properly attached to the electric wire holding groove 3a, the pressing of the electric wire 5 by the press-fitting blade 7b becomes difficult, or There is a possibility that an accident such as breakage of the electric wire 5 may be caused, which is a great obstacle to the automation of the electric wire wiring.
Accordingly, an object of the present invention is to eliminate the above-mentioned problem, and by inserting a wire into a wire holding groove of a plurality of wire press-fitting ribs arranged on the wire routing member, a conductor circuit having a predetermined shape is connected to the wire. It is an object of the present invention to provide a good wiring machine capable of facilitating the automation of a wiring operation formed on a wiring member.
[0008]
[Means for Solving the Problems]
  The above object of the present invention is to form a conductor circuit by sequentially pushing the wires sent from the wire feeding means of the wiring head into the wire holding grooves of a plurality of wire press-fitting ribs arranged on the wire routing member. A wiring machine that performs
  The wiring head attached to the head moving means and movable is arranged at a lower end portion of the electric wire feeding means and sends an electric wire, and is arranged on the downstream side in the traveling direction of the electric wire sending portion, A press-fitting blade that can be moved up and down to press-fit the sent electric wire into the electric wire clamping groove, and is extended in the press-fitting blade advancing and retreating direction so as to sandwich the press-fitting blade from both sides, and sent from the electric wire sending part An electric wire guide part formed with a guide groove through which the electric wire can be inserted,
  When the press-fitting blade advances and pushes the electric wire into the electric wire holding groove, the electric wire is guided in the extending direction of the electric wire holding groove by the electric wire guide portion.,
  When the head moving means passes through a position further spaced downstream from the downstream end of the guide groove in the wire guide portion, further downstream at the outlet in the wiring direction of the wire clamping groove of the wire press-fitting rib located at the downstream end. The wiring head is turned toward the entrance in the wiring direction of the wire holding groove of the wire press-fitting rib located, and the electric wire holding of the wire press-fitting rib is made at the inlet of the wire holding groove of the wire press-fitting rib located downstream. Rotate the wiring head until it matches the groove axis and change the direction of movementThis is achieved by a wiring machine characterized by this.
[0009]
According to the wiring machine having the above configuration, when the wiring head sequentially moves between the wire press-fitting ribs, the electric wire sent out from the electric wire feeding portion is inserted into the guide groove of the electric wire guide portion, and the electric wire is at least the electric wire. The delivery direction at the portion inserted through the guide groove is restricted.
Therefore, when the wiring head is guided on the next press-fitting target wire press-fitting rib, the guide groove of the electric wire guide part that determines the feeding direction of the electric wire is the electric wire of the press-fitting target wire press-fitting rib. The wiring head is moved so as to coincide with the extending direction of the holding groove.
[0010]
When the direction of the guide groove of the wire guide portion coincides with the extending direction of the wire holding groove of the wire press-fitting rib, the wiring head is lowered as it is, and the guide groove is in a state of being substantially in communication with the wire holding groove. To do.
In this state, even when the wire outlet of the wire clamping groove of the wire press-fitting rib located upstream from the wire press-fitting rib to be press-fitted is out of the extending direction of the wire clamping groove of the wire press-fitting rib to be press-fitted, The portion of the electric wire that is pushed into the press-fitting blade is straightened by the guide groove of the electric wire guide portion so that the feeding direction follows the electric wire holding groove, and is accurately supported by the electric wire holding groove.
Therefore, if the press-fitting blade is advanced in this state and the electric wire in the state along the electric wire holding groove is pushed into the electric wire holding groove, the press-fitting can be surely performed.
[0011]
Therefore, the wire guided by the wiring head does not cross the upper edge of the opposing wall forming the wire clamping groove of the wire press-fitting rib to be press-fitted, so the press-fitting operation of the wire to each wire press-fitting rib is ensured. This can be implemented, and it is possible to facilitate the automation of the wiring operation by the wiring machine that forms the conductor circuit having a predetermined shape on the electric wire wiring member.
[0012]
  In the present invention,The head moving means is a downstream end of a guide groove in the wire guide portion.An axis passing through a position further downstream fromThe moving direction is changed by turning the wiring head as a center of rotation. In this case, after the wiring head has finished press-fitting the electric wire into the electric wire press-fitting rib, the wiring head is moved until the downstream end of the guide groove in the electric wire guide part passes through the electric wire holding groove of the electric wire press-fitting rib. Then turn to change the direction of movement of the wiring head. As a result, even if the wiring head is largely swung toward the downstream wire press-fitting rib, the wire guide portion does not give excessive tension to the wire inserted in the guide groove, and the upstream side There is no risk of dropping off the wires press-fitted into the wire press-fitting ribs or detaching the wires inserted into the guide grooves.Preferably, the distance between the axis of rotation center from the downstream end of the guide groove does not hinder the bending of the wire when the wiring head is swiveled near the press-fitted wire press-fitting rib. It is set to the minimum necessary level.
[0013]
In addition, after the wiring head is guided on the next press-fitting target wire press-fitting rib, the guide guide groove of the electric wire guide portion is aligned with the extending direction of the electric wire clamping groove of the press-fitting target wire press-fitting rib. When turning the wire head largely, the wire head is moved and turned until the downstream end of the guide groove in the wire guide portion coincides with the extending direction of the wire holding groove. Thereby, even if the wiring head is swiveled largely until it coincides with the extending direction of the electric wire holding groove, the electric wire guide portion does not give excessive tension to the electric wire inserted through the guide groove, The electric wire inserted into the guide groove does not come off and is not supported in a state of being attached to the electric wire holding groove.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a wiring machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
1 and 2 are a partial cross-sectional side view and a front view of a wiring machine according to an embodiment of the present invention, FIG. 3 is an enlarged cross-sectional view of a main part of the wiring head shown in FIG. 1, and FIG. FIG. 5 to FIG. 7 are a partial sectional side view and an enlarged view of a main part for explaining the operation of the wiring head shown in FIG. 1, and FIGS. 8 and 9 are cloths shown in FIG. FIG. 10 and FIG. 11 are enlarged views of a main part for explaining a specific operation procedure according to another form of the routing surface of the wiring head shown in FIG. 1. .
[0015]
As shown in FIGS. 1 and 2, the wiring machine 11 of the present embodiment is attached to a head moving means (not shown) and movable in a three-dimensional direction, for example, as shown in FIG. The predetermined conductor circuit 6 is formed by sandwiching the electric wire 5 in order between the plurality of electric wire press-fitting ribs 3 on the electric wire routing member 1.
The wiring head 17 is provided at the lower end portion of the wire feeding means 21 and is a wire nozzle 13 that is a wire feeding portion that feeds the wire 5, and a downstream side in the traveling direction of the wire nozzle 13 (right side in FIG. 1). The press-fitting blade 15 that can be moved up and down to press-fit the delivered electric wire 5 into the electric wire holding groove 3a of the electric wire press-fitting rib 3, and the press-fitting blade advancing and retreating direction so as to sandwich the press-fitting blade 15 from both sides And a wire guide portion 25 in which a guide groove 27 is formed through which the wire 5 sent from the wire nozzle 13 can be inserted, and the wire 5 sent from the wire nozzle 13 is cut to a predetermined length. An electric wire cutter 23 is provided.
[0016]
As the head moving means, a known three-axis moving mechanism that can move the wiring head 17 in an arbitrary amount in the three-axis directions of the X axis, the Y axis, and the Z axis orthogonal to each other can be used. And the said head moving means can also turn the said wiring head 17 centering | focusing on the axis line 19 which passes the downstream end vicinity of the guide groove 27 in the said wire guide part 25. As shown in FIG.
Here, the distance of the axis 19 from the downstream end of the guide groove 27 is such that the bending of the wire 5 is hindered when the wiring head 17 is swiveled near the press-fitted wire press-fitting rib 3. What is necessary is just to set to the minimum necessary to the extent that it does not occur.
[0017]
The electric wire supply means 21 includes a driving roller 31 and a nip roller 32 that sandwich the electric wire 5 supplied from a drum (not shown) and guided to the electric wire feeding cylinder 29.
The drive roller 31 is rotationally driven by an electric motor 35 via a gear mechanism 34. In addition, the nip roller 32 can adjust a holding interval with the driving roller 31 via an air cylinder 36 and a link 37.
[0018]
Therefore, the electric wire supply means 21 can send out the electric wire 5 at an arbitrary speed by controlling the electric motor 35 to rotate. Further, by increasing the holding interval between the driving roller 31 and the nip roller 32 to a predetermined value or more, the holding of the electric wire 5 can be released, and the electric wire 5 can be pulled out by the tension acting on the electric wire 5 sent out from the electric wire nozzle 13. it can.
[0019]
As shown in FIGS. 3 and 4, the wire guide portion 25 fixed in the vicinity of the press-fitting blade 15 in the wiring head 17 extends downward along the press-fitting blade advancing and retreating direction from both sides of the press-fitting blade 15. The pair of wall portions 25a and 25a are used to position the electric wire 5 delivered from the electric wire nozzle 13 along the extending direction of the electric wire holding groove 3a over the length corresponding to the length of the electric wire holding groove 3a. A guide groove 27 is formed.
[0020]
As shown in FIG. 3, the press-fitting blade 15 has a notch 15a having a width corresponding to the length of the electric wire holding groove 3a at an intermediate portion, and two projecting portions 15b and 15b on both sides of the notch 15a. The wire 5 is pressed against the wire 5 and pushed into the wire holding groove 3 a of the wire press-fitting rib 3.
Therefore, when the press-fitting blade 15 moves forward and pushes the electric wire 5 into the electric wire holding groove 3a, at least a portion of the electric wire 5 to be pushed into the electric wire holding groove 3a is guided by the guide groove 27 of the electric wire guide portion 25. It is reliably guided in the extending direction of the holding groove 3a.
[0021]
And the said wiring machine 11 is a wiring head part so that the electric wire 5 sent out from the said electric wire nozzle 13 may pass on the electric wire clamping groove 3a of the electric wire press-fitting rib 3 arrange | positioned on the electric wire routing member 1. FIG. 17 by moving a head moving step of moving the wire 17 and a wire pushing step of pushing the wire 5 laid on the wire holding groove 3a into the wire holding groove 3a by the press-fitting blade 15 by the head moving step. A conductor circuit is formed through a plurality of wire press-fitting ribs 3 arranged on the member 1.
[0022]
Therefore, first, at the start of the operation in which the wiring machine 11 starts the routing process, the electric wire 5 introduced and guided in the electric wire feeding tube 29 is inserted into the electric wire nozzle 13. At this time, the electric wire 5 can be freely inserted between the nip roller 32 and the drive roller 31 by making the nip roller 32 open with respect to the drive roller 31.
Then, the nip roller 32 and the driving roller 31 are closed, and the electric wire 5 having a predetermined length is put in a holding state in which the electric wire 5 can be sent out according to the rotational driving amount by the electric motor 35. Furthermore, the electric wire cutter 23 arranged above the electric wire nozzle 13 is driven by the drive cylinder 24, so that the end of the electric wire sent from the electric wire nozzle 13 is cut off and the end portion of the electric wire 5 is trimmed to the cutter position. Put it in a state. When the above preparation work is completed, the routing process can be started.
[0023]
Hereinafter, the operation of the wiring head 17 in the routing process of the wiring machine 11 will be described.
First, in the head moving step, the wiring head 17 is moved onto the target wire press-fitting rib 3 by a head moving means (not shown) (see FIG. 1). At this time, the electric wire 5 is sent out by the electric wire supply means 21 while measuring the length corresponding to the moving distance of the wiring head 17.
[0024]
Further, when the wiring head 17 sequentially moves between the wire press-fitting ribs 3, 3, the wire 5 fed from the wire nozzle 13 is inserted into the guide groove 27 of the wire guide portion 25, and the wire 5 is at least The delivery direction at the portion inserted through the guide groove 27 is restricted.
Therefore, when the wiring head 17 is guided onto the next press-fitting target wire press-fitting rib 3, the direction of the guide groove 27 of the electric wire guide portion 25 that determines the feeding direction of the electric wire 5 is: When the wiring head 25 is moved so as to coincide with the extending direction of the wire clamping groove 3a of the wire press-fitting rib 3 to be press-fitted, the wire guide head 25 is turned around the axis 19 to adjust the direction of the wire guide portion 25. Do
[0025]
When the direction of the guide groove 27 of the wire guide portion 25 coincides with the extending direction of the wire clamping groove 3a of the wire press-fitting rib 3, as shown in FIG. 5, the wiring head 17 is lowered as it is, The lower ends of the pair of wall portions 25a and 25a of the wire guide portion 25 are brought close to the upper end surfaces of the pair of opposing walls 3b and 3b of the wire press-fitting rib 3 (see FIG. 6A). That is, the guide groove 27 of the wire guide portion 25 and the wire holding groove 3a of the wire press-fitting rib 3 are opposed to each other so as to be in a substantially communicated state.
[0026]
Next, in the electric wire pushing process, as shown in FIG. 6A, the guide groove 27 of the electric wire guide portion 25 is positioned on the electric wire holding groove 3a of the electric wire press-fitting rib 3 to thereby form the electric wire holding groove 3a. After the electric wire 5 is positioned on the upper side, the press-fitting blade 15 is advanced by the press-fitting blade drive cylinder 33 so that the electric wire guide portion 25 guides the electric wire holding groove 3a in the extending direction as shown in FIG. The electric wire 5 is pushed into the electric wire holding groove 3a.
[0027]
Further, when there is a possibility that a certain tension or more is applied to the electric wire 5 at the time of press-fitting, the holding interval between the driving roller 31 and the nip roller 32 of the electric wire supply means 21 is widened in advance to a predetermined value or more.
When the press-fitting of the electric wire 5 is completed, as shown in FIG. 6C, the press-fitting blade 15 is returned to the initial position, and the drive roller 31 and the nip roller 32 are used for guidance to the next electric wire press-fitting rib 3. The electric wire 5 is clamped.
Next, the wiring head 17 is advanced along the wire holding groove 3a until the downstream end of the guide groove 27 in the wire guide portion 25 is disengaged from the wire holding groove 3a of the press-fitted wire pressing rib 3. Thereafter, the wire head 17 is lowered by a predetermined amount, so that the electric wire 5 is reliably inserted into the guide groove 27.
[0028]
Then, while the electric wire supply means 21 sends out the electric wire 5 having a length corresponding to the moving distance of the wiring head 17, the head moving means (not shown) again causes the wiring head 17 to be moved as shown in FIG. It is moved on the target wire press-fitting rib 3.
By repeating the head moving process and the pushing process described above, a predetermined conductor circuit is arranged on the wire routing member 1. Then, by driving the electric wire cutter 23 by the drive cylinder 24, the end of the electric wire sent from the electric wire nozzle 13 is cut and wiring of a predetermined conductor circuit is completed.
[0029]
Therefore, according to the wiring machine 11 of the present embodiment, the upper end edge of the opposing walls 3b and 3b in which the electric wire 5 guided by the wiring head 17 forms the electric wire holding groove 3a of the electric wire press-fitting rib 3 to be press-fitted. There is no crossing.
Therefore, it is possible to reliably perform the press-fitting operation of the electric wires 5 into the electric wire press-fitting ribs 3 and to facilitate the automation of the wiring operation by the wiring machine 11 that forms the conductor circuit having a predetermined shape on the electric wire wiring member 1. it can.
[0030]
Next, as shown in FIG. 8 (a), the wire outlet 3c of the wire clamping groove 3a of the wire press-fitting rib 3 located on the upstream side of the wire press-fitting rib 3 to be press-fitted is the wire press-fitting rib 3 to be press-fitted. The operation of the wiring head 17 in the routing process in the case where the wire holding groove 3a is not in the extending direction L will be described.
First, as shown to Fig.8 (a), the press-in process is implemented and the press injection of the electric wire 5 with respect to the electric wire clamping groove 3a of the upstream electric wire press-fitting rib 3 is completed.
[0031]
Next, as shown in FIG. 8 (b), the axis 19 set near the downstream end of the guide groove 27 in the wire guide portion 25 as the rotation center when the wiring head 17 is swung has been press-fitted. The wiring head 17 is advanced along the electric wire holding groove 3a until the electric wire pressing rib 3 is removed from the electric wire holding groove 3a. Thereafter, the wire head 17 is lowered by a predetermined amount, so that the electric wire 5 is reliably inserted into the guide groove 27.
Next, as shown in FIG. 8C, the wiring head 17 is moved around the axis line 19 until the wiring head 17 faces the wire entrance of the wire holding groove 3a of the wire press-fitting rib 3 to be press-fitted downstream. Turn.
[0032]
In this way, when the wiring head 17 is moved toward the wire press-fitting rib 3 on the downstream side, the wiring head 17 is centered on the axis 19 set near the downstream end of the guide groove 27 in the wire guide portion 25. , The wire guide portion 25 does not apply excessive tension to the wire 5 inserted through the guide groove 27 of the wire guide portion 25, and is pressed into the upstream wire press-fitting rib 3. Therefore, there is no possibility that the electric wire 5 is dropped or the electric wire 5 inserted into the guide groove 27 is detached.
[0033]
When the wiring head 17 has to be swung largely and there is a possibility that the upstream electric wire 5 may be pulled, the holding of the electric wire 5 by the drive roller 31 and the nip roller 32 is released, or the electric wire is supplied as necessary. By carrying out the feeding of the electric wire 5 by the means 21, it is possible to prevent a predetermined tension or more from acting on the electric wire 5.
[0034]
And as shown to Fig.9 (a), the wiring head 17 is induced | guided | derived until the said axis line 19 is located just before the electric wire entrance of the electric wire clamping groove 3a of the electric wire press-fitting rib 3 of downstream press-fitting object.
Next, the wiring head 17 positioned on the wire press-fitting rib 3 is swiveled around the axis 19, and the direction of the guide groove 27 of the wire guide portion 25 is set to the wire as shown in FIG. 9B. It adjusts so that it may correspond to the extension direction of the electric wire clamping groove 3a of the press-fit rib 3.
[0035]
At this time, even if the wiring head 17 is swung so that the guide groove 27 of the wire guide portion 25 coincides with the extending direction L of the wire clamping groove 3a of the wire press-fitting rib 3 to be press-fitted, the axis 19 can be rotated. If the wiring head 17 is swiveled as a rotation center, the wire guide portion 25 is not inserted into the guide groove 27 without applying excessive tension to the wire 5 inserted through the guide groove 27. There is no case where the existing electric wire 5 comes off and is not supported in a state of being attached to the electric wire holding groove 3a. Of course, a predetermined tension or more acts on the electric wire 5 by releasing the holding of the electric wire 5 by the driving roller 31 and the nip roller 32 or by feeding the electric wire 5 by the electric wire supply means 21 as necessary. Can also be prevented.
[0036]
And if the direction of the guide groove 27 of the said wire guide part 25 corresponds with the extending direction of the electric wire clamping groove 3a of the electric wire press-fitting rib 3, the said wiring head 17 will be dropped as it is, and a pair of wall of the electric wire guide part 25 will be carried out. The lower ends of the portions 25a and 25a are brought close to the upper end surfaces of the pair of opposing walls 3b and 3b of the wire press-fitting rib 3 (see FIG. 6A).
[0037]
Then, as shown in FIGS. 8 and 9, the wire outlet 3 c of the wire clamping groove 3 a of the wire press-fitting rib 3 located upstream of the press-fitting target wire press-fitting rib 3 is connected to the press-fitting target wire press-fitting rib 3. Even when the wire clamping groove 3a is deviated from the extending direction L, the portion of the wire 5 pushed into the press-fitting blade 15 is corrected by the guide groove 27 of the wire guide portion 25 so that the feeding direction is linear with the wire clamping groove 3a. Then, it is supported in a state where it exactly follows the wire clamping groove 3a.
Therefore, if the press-fitting blade 15 is advanced in this state and the electric wire 5 in a state along the electric wire holding groove 3a is pushed into the electric wire holding groove 3a while being guided by the guide groove 27, the electric wire 5 is securely inserted. Can be press-fitted.
[0038]
That is, in the wiring machine 11 of the present embodiment, the direction and position of the electric wire 5 sent out from the electric wire nozzle 13 is aligned with the electric wire holding groove 3 a of the electric wire press-fitting rib 3 by the electric wire guide portion 25 provided in the wiring head 17. Accordingly, the wire head 17 can be accurately positioned on the wire clamping groove 3 a of the wire press-fitting rib 3 by the turning operation of the wiring head 17.
Therefore, even when the electric wire 5 is routed between the electric wire press-fitting ribs 3 and 3 having different installation directions, the induced electric wire 5 does not cross the upper end edges of the pair of opposing walls 3b and 3b of the electric wire press-fitting rib 3, The press-fitting work to the wire press-fitting ribs 3 and 3 can be reliably performed, and the wiring work of the electric wires 5 can be easily automated.
[0039]
Furthermore, the wiring machine 11 according to the present embodiment has an extra wire as in the conventional wiring machine for preventing the press-fitted electric wire 5 from falling off the electric wire press-fitting rib 3 when the wiring head 17 turns. Such as a simple feeding operation and a moving operation for largely retracting the wiring head 17 from the wire press-fitting rib 3 are not required. Therefore, the wiring machine 11 of the present embodiment can be routed by the shortest route, and can reduce the wiring process as compared with the conventional wiring machine and can improve work efficiency.
[0040]
Next, as shown in FIG. 10, when the installation surface 20 of the wire press-fitting rib 3 is an inclined surface, a tension more than necessary acts on the electric wire 5 during horizontal movement of the wiring head 17, and the wire press-fitting rib. There is a possibility that the press-fitted electric wire 5 will drop off.
Therefore, before the wiring head 17 is moved horizontally toward the downstream wire press-fitting rib 3, the wire 5 is fed by the wire supply means 21 to give an appropriate extra length, If the holding of the electric wire 5 by the nip roller 32 is cancelled, the tension more than necessary does not act on the electric wire 5, and a good wiring is possible.
[0041]
Furthermore, as shown in FIG. 11, in the routing process when the two wire press-fitting ribs 3, 3 arranged on the wire routing member are respectively provided on the installation surfaces 20 a, 20 b having a large height difference. The operation of the wiring head 17 will be described.
First, as shown in FIG. 11 (a), the press-in process is performed to complete the press-fitting of the electric wire 5 into the electric wire holding groove 3a of the upstream electric wire press-fitting rib 3 protruding from the installation surface 20a.
[0042]
Next, as shown in FIG. 11 (b), while the wire 5 having a length corresponding to the moving distance of the wiring head 17 is sent out by the wire supply means 21, the wiring head 17 is moved horizontally to guide the wire 5. The part 25 is moved on the vertical line of the next target wire press-fitting rib 3 projecting from the installation surface 20b.
Thereafter, as shown in FIG. 11C, the wiring head 17 is lowered in a state where the electric wire 5 is inserted into the guide groove 27. At this time, feeding control of the electric wire 5 is appropriately performed by the electric wire supply means 21 so that the upstream electric wire 5 does not come into contact with the downstream edge of the guide groove 27 or come off from the guide groove 27.
[0043]
Next, as shown in FIG. 11 (d), the wire guide portion 25 is positioned so that the direction of the guide groove 27 of the wire guide portion 25 coincides with the extending direction of the wire holding groove 3 a of the wire press-fitting rib 3. The lower end of 25 is brought close to the upper end surface of the wire press-fitting rib 3.
And in an electric wire pushing process, as shown in FIG.11 (e), by moving the press-fit blade 15 forward, it guides the electric wire 5 to the extending direction of the electric wire clamping groove 3a by the guide groove 27, and this electric wire clamping groove | channel. It can be pushed into 3a.
[0044]
Therefore, even when the two wire press-fitting ribs 3 and 3 arranged on the electric wire routing member are respectively provided on the installation surfaces 20a and 20b having a large difference in height, the induced electric wire 5 is provided on the downstream side. 3 is prevented from crossing the upper edge of the pair of opposing walls 3b, 3b, the press-fitting work to the respective press-fitting ribs 3, 3 can be reliably performed, and the wiring work of the electric wires 5 can be easily automated. it can.
[0045]
The configurations of the wiring head, the wire feeding means, the wire feeding portion, the press-fitting blade, the wire guide portion and the like in the wiring machine of the present invention are not limited to the configurations of the above-described embodiments, and the gist of the present invention. It goes without saying that various forms can be adopted based on the above.
[0046]
【The invention's effect】
According to the wiring machine of the present invention, when the wiring head sequentially moves between the wire press-fitting ribs, the wire sent from the wire sending portion is inserted into the guide groove of the wire guide portion, and the wire is at least the wire The delivery direction at the portion inserted through the guide groove is restricted.
Therefore, when the wiring head is guided on the next press-fitting target wire press-fitting rib, the guide groove of the electric wire guide part that determines the feeding direction of the electric wire is the electric wire of the press-fitting target wire press-fitting rib. The wiring head is moved so as to coincide with the extending direction of the holding groove.
[0047]
When the direction of the guide groove of the wire guide portion coincides with the extending direction of the wire holding groove of the wire press-fitting rib, the wiring head is lowered as it is, and the guide groove is in a state of being substantially in communication with the wire holding groove. To do.
In this state, even when the wire outlet of the wire clamping groove of the wire press-fitting rib located upstream from the wire press-fitting rib to be press-fitted is out of the extending direction of the wire clamping groove of the wire press-fitting rib to be press-fitted, The portion of the electric wire that is pushed into the press-fitting blade is straightened by the guide groove of the electric wire guide portion so that the feeding direction follows the electric wire holding groove, and is accurately supported by the electric wire holding groove.
[0048]
  Therefore, if the press-fitting blade is advanced in this state and the electric wire in the state along the electric wire holding groove is pushed into the electric wire holding groove, the press-fitting can be surely performed. Therefore, the wire guided by the wiring head does not cross the upper edge of the opposing wall forming the wire clamping groove of the wire press-fitting rib to be press-fitted, so the press-fitting operation of the wire to each wire press-fitting rib is ensured. This can be implemented, and it is possible to facilitate the automation of the wiring operation by the wiring machine that forms the conductor circuit having a predetermined shape on the electric wire wiring member.
  Further, according to the wiring machine of the present invention, the head moving means swivels the wiring head around an axis passing through a position spaced further downstream from the downstream end of the guide groove in the wire guide portion. Change the direction of movement. In this case, after the wiring head has finished press-fitting the electric wire into the electric wire press-fitting rib, the wiring head is moved until the downstream end of the guide groove in the electric wire guide part passes through the electric wire holding groove of the electric wire press-fitting rib. Then turn to change the moving direction of the wiring head. As a result, even if the wiring head is largely swung toward the downstream wire press-fitting rib, the wire guide portion does not give excessive tension to the wire inserted through the guide groove, and the upstream side There is no risk of dropping off the wires press-fitted into the wire press-fitting ribs and detaching the wires inserted into the guide grooves.
