【０００１】
【発明の属する技術分野】
本発明は可撓性を有する線状体を加工処理して製造する線状体製造方法及び線状体製造装置に関するものである。
【０００２】
【従来の技術】
電線、管、ホース等の可撓性を有する長尺な線状体に切断、被覆剥取り加工、表面処理、端子等の接続部材の装着等といった加工処理を施して製造する線状体製造方法は、通常、図６に示すような線状体製造装置１０を用いて行われる。
【０００３】
その製造装置１０は、例えば、測長機構２を有し、線状体Ｗを所定長毎に間欠的に送り出す無限軌道式等の線状体送出機１と、例えば、駆動機構（図示せず）により相対的に開閉作動する一対のカッター部材４を有し、線状体Ｗを所定長毎に切断加工する線状体加工処理機３と、線状体加工処理機３の線状体入口側に設けられ、駆動機構（図示せず）により相対的に開閉作動する一対のクランプ部材７を有する第１のクランプ５と、線状体加工処理機３の線状体出口側に設けられ、駆動機構（図示せず）により相対的に開閉作動する一対のクランプ部材７を有する第２のクランプ６とを備えている（図７（ａ）（ｂ）参照）。
【０００４】
従来の線状体製造方法を前記製造装置１０を用いて説明すると、先ず線状体送出機１により所定長毎に間欠的に送り出される線状体Ｗを、クランプ部材７を開いた第１のクランプ５（図７（ａ）参照）、カッター部材４を開いた線状体加工処理機３（図６参照）及びクランプ部材７を開いた第２のクランプ６（図７（ａ）参照）に通過させる。次に、線状体Ｗが所定長送り出されたときに、測長機構２からの指令で線状体送出機１の運転、即ち、線状体Ｗの送り出しを停止する。次に、第１、第２のクランプ５、６のクランプ部材７を駆動機構の閉作動により閉じて線状体Ｗを把持する（図７（ｂ）参照）。次に、線状体加工処理機３のカッター部材４を駆動機構の閉作動により閉じて線状体Ｗを切断し、線状体Ｗの加工処理作業を行う。その後、必要に応じて、例えば、その切断端末の外周面の被覆を剥ぎ取り、端子等を圧着等により装着する作業を行う（特許文献１参照）。

【発明が解決しようとする課題】
線状体Ｗを線状体加工処理機３で加工処理して製造する場合には、予め線状体Ｗを第１、第２のクランプ５、６の開いたクランプ部材７間に所定長通過させ、クランプ部材７を閉作動して、線状体Ｗの加工処理作業中に線状体Ｗが動かないように把持する必要がある。
【０００７】
ところで、線状体Ｗは一般的に可撓性を有し、また、ドラム、リール等に巻いてある場合には曲がり癖が付き易いので、線状体送出機１から線状体Ｗを送り出して線状体加工処理機３に供給する際、走行する線状体Ｗがうねったり、蛇行したりしてまっすぐにならず、線状体Ｗが下流側に走行するほど、線状体Ｗの軸線が線状体製造装置のセンターラインからずれ易い。
【０００８】
特に、線状体Ｗを線状体加工処理機３の下流側に設けられた第２のクランプ６のクランプ部材７間に通過させる際、線状体Ｗが破線で示すクランプエリアＡ（図７（ａ）（ｂ）参照）内から外方に外れ易く、最悪の場合、クランプ部材７からはみ出すこともあり、線状体Ｗの把持不良（クランプミス）が生じて、線状体Ｗを確実に把持することができなくなることがある。このため、線状体の加工処理作業能率、加工処理して製造された線状体Ｗの歩留まり及び品質が低下する問題があった。
【０００９】
本発明は上記課題を解決し、線状体を加工処理して製造する際、線状体の把持不良を防止して線状体を確実に把持し、線状体の加工処理作業能率、加工処理して製造された線状体の歩留まり及び品質を向上させることができる線状体製造方法及び線状体製造装置を提供することを目的とするものである。
【００１０】
【課題を解決するための手段】
前記目的を達成するために、本発明の請求項１に記載された発明は、線状体加工処理機の線状体入口側と線状体出口側に、線状体を把持するクランプ部材を有する第１のクランプと第２のクランプとを設け、線状体を第１のクランプ、線状体加工処理機及び第２のクランプに所定長通過させ、第１、第２のクランプのクランプ部材を閉じて線状体を把持した後、線状体を線状体加工処理機で加工処理する線状体製造方法において、少なくとも第２のクランプのクランプ部材を、線状体に対して押圧しないがクランプ部材の領域内に閉じ込める半閉姿勢にして、線状体を第１、第２のクランプ内に通過させ、その後、線状体を複数加工処理する際、少なくとも後加工処理する側のクランプをこれに線状体を通過させる前は、線状体加工処理機の近傍に配置し、線状体を通過させる過程、又は、通過終了後、線状体を把持するまでの間で、線状体加工処理機から線状体の長手方向に沿って所定距離離反させることを特徴とするものである。
【００１１】
このように、少なくとも第２のクランプのクランプ部材を、線状体に対して押圧しないがクランプ部材の領域内に閉じ込める半閉姿勢にして、線状体を第１、第２のクランプ内に通過させると、線状体がクランプを通過する際、うねったり、蛇行したり等して曲がっていても、半閉姿勢に保持して線状体との隙間が狭くなったクランプのクランプ部材によって曲がりを矯正され、線状体がクランプのクランプエリアから外れることがなくなる。従って、クランプのクランプ部材を閉じたとき、線状体の把持不良（クランプミス）がなくなり、線状体を確実に把持することができると共に、線状体の加工処理作業能率、加工処理して製造された線状体Ｗの歩留まり及び品質を向上させることができる。
【００１３】
また、線状体を複数加工処理する際、少なくとも後加工処理する側のクランプをこれに線状体を通過させる前は、線状体加工処理機の近傍に配置し、線状体を通過させる過程、又は、通過終了後、線状体を把持するまでの間で、線状体加工処理機から線状体の長手方向に沿って所定距離離反させると、第１、第２のクランプ間の距離が短くなるので、線状体の軸線が線状体製造装置のセンターラインから過度にずれるようなことがなく、線状体を第１、第２のクランプに入れて把持することが容易になり、線状体の把持不良をより少なくすることができる。
【００１４】
また、線状体を複数加工処理する際、後加工処理が線状体を長手方向に移動させることにより行う場合、その加工処理を前加工処理終了後、線状体を後加工処理する側のクランプで把持した状態で長手方向に移動させることにより行うことが可能になり、線状体の加工処理作業能率をより向上させることができる。
【００１５】
本発明の請求項２に記載された発明は、線状体加工処理機の線状体入口側と線状体出口側に、線状体を把持するクランプ部材を有する第１のクランプと第２のクランプとを設け、線状体を第１、第２のクランプで把持し、線状体加工処理機で加工処理するようにした線状体製造装置において、少なくとも第２のクランプが、そのクランプ部材を線状体に対して押圧しないがクランプ部材の領域内に閉じ込める半閉姿勢に保持する構成を備え、また、線状体を複数加工処理する際、少なくとも後加工処理する側のクランプをこれに線状体を通過させる前は、線状体加工処理機の近傍に配置し、線状体を通過させる過程、又は、通過終了後、線状体を把持するまでの間で、線状体加工処理機から線状体の長手方向に沿って所定距離離反させる搬送機構を備えていることを特徴とするものである。
【００１６】
このような構成によると、線状体の曲がりを矯正するために複雑な機構にする必要がないので、装置構造が簡単になり、該装置を手数をかけずに安価に製造又は改造することができると共に、線状体の把持不良を確実に防止し、線状体を能率よく加工処理して製造することができ、また、線状体加工処理機から線状体の長手方向に沿って所定距離離反させる搬送機構を備えているので、線状体の加工処理作業をより向上させることができる。
【００１７】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。図１は本発明に係る線状体製造方法を実施するのに使用する線状体製造装置１１の主要部の概要を示す一部省略斜視図、図２は線状体製造装置１１の概略平面図、図３は第２のクランプ２３で線状体Ｗを把持する状態を示すもので、（ａ）はクランプ部材２５が開いた第２のクランプ２３に線状体Ｗを通過させる状態の説明図、（ｂ）はクランプ部材２５が半閉姿勢の第２のクランプ２３に線状体Ｗを通過させる状態の説明図、（ｃ）はクランプ部材２５が閉じた第２のクランプ２３に線状体Ｗを把持した状態の説明図である。なお、本実施形態の線状体Ｗは、例えば、ワイヤーハーネス用のゴム、プラスチック絶縁電線の場合を示す。
【００１８】
本発明の線状体製造装置１１は、測長機構１５を有し、線状体Ｗを所定長毎に間欠的に送り出す無限軌道式の線状体送出機１３と、例えば、流体圧シリンダ等の駆動機構（図示せず）により相対的に開閉作動する一対のカッター部材１９を有し、線状体Ｗを所定長毎に切断加工する線状体切断機からなる線状体加工処理機１７と、線状体加工処理機１７の線状体入口側に設けられ、流体圧シリンダ等の駆動機構（図示せず）により相対的に開閉作動する一対のクランプ部材２２を有する第１のクランプ２１と、線状体加工処理機１７の線状体出口側に設けられ、流体圧シリンダ等の駆動機構（図示せず）により相対的に開閉作動する一対のクランプ部材２５を有する第２のクランプ２３とを備えている。本実施形態では、第１、第２のクランプ２１、２３が後記するように、そのクランプ部材２２、２５を線状体Ｗに対して押圧しないがクランプ部材２２、２５の領域内に閉じ込める半閉姿勢に保持する構成を備えている。
【００１９】
線状体加工処理機１７の各カッター部材１９は、図１に示すように、幅方向の中央位置に切断刃１９ａと両側位置に被覆剥取刃１９ｂが形成され、上下方向に対向して配置され、駆動機構により相対的に開閉作動するように構成される。
【００２０】
第１のクランプ２１のクランプ部材２２は、線状体Ｗを把持する内側面に長手方向に沿って凹凸部２２ａが形成されて、クランプ部材２２を閉じて線状体Ｗを把持したときにかみ合うようになっている。また、図示しないが、各内側面の幅方向の中央部に線状体Ｗを案内するＶ形状凹溝が形成されている。そして、一対のクランプ部材２２は、線状体Ｗを把持する内側面が垂直になるように横方向に対向配置され、駆動機構の開作動に平行状態を維持して相対的に開いて線状体Ｗを通過させたり、駆動機構の閉作動により相対的に閉じたりして線状体Ｗを把持したり、クランプ部材２２を線状体Ｗに対して押圧しないがクランプ部材２２の領域内に閉じ込める半閉姿勢に保持したりする構成になっている。
【００２１】
第２のクランプ２３の一対のクランプ部材２５は、線状体Ｗを把持する内側面に長手方向に沿って凹凸部２５ａが形成されて、クランプ部材２５を閉じて線状体Ｗを把持したときにかみ合うようになっている。また、各内側面の幅方向の中央部に線状体Ｗを案内するＶ形状の凹溝２５ｂが形成されている。そして、一対のクランプ部材２５は、線状体Ｗを把持する内側面が横になるように縦（上下）方向に配置され、幅方向の一方の側部に装着されたヒンジ機構（図示せず）に回動自在に連結され、駆動機構（図示せず）により開口が横方向を向くように上下方向にＶ形状に相対的に開いて線状体Ｗを通過させたり（図３（ａ）参照）、クランプ部材２２を線状体Ｗに対して押圧しないがクランプ部材２２の領域内に閉じ込める半閉姿勢に保持して、線状体Ｗを整直しながら通過させたり（図３（ｂ）参照）、ほぼ平行状態になって相対的に閉じて線状体Ｗを把持したり（図３（ｃ）参照）するようになっている。
【００２２】
なお、第１、第２のクランプ２１、２３のクランプ部材２２、２５の配置状態、開閉機構は前記構成のものに限定されるものではない。例えば、クランプ部材２２、２５が平行状態を保持しながら、相対的に開いたり、閉じたり、半閉姿勢に保持したりして、間隔を離接近自在に可変できるようにしたものでもよい。また、第１のクランプ２１はクランプ部材２２を線状体Ｗに対して押圧しないがクランプ部材２２の領域内に閉じ込める半閉姿勢に保持する構成を備えなくてもよい。
【００２３】
また、図２に示すように、第１のクランプ２１の一側方には、線状体Ｗの前方切断端末に端子２７を圧着により接続するための第１端子圧着機２９が設けられ、また、第２のクランプ２３の他側方には、線状体Ｗの後方切断端末に端子２７を圧着により接続するための第２端子圧着機３１が設けられ、更に線状体Ｗ、即ち、第１、第２のクランプ２１、２３を第１端子圧着機２９、第２端子圧着機３１に矢印ＳＲ方向にそれぞれ往復搬送したり、線状体Ｗの軸線方向に沿った矢印ＰＱ方向に往復移動したりする第１搬送機構３３、第２搬送機構３５が設けられる。更に第２端子圧着機３１の近傍には、加工処理済の線状体Ｗを取り出すための線状体取出機３７が設けられる。
【００２４】
本発明の線状体製造方法を線状体製造装置１１を用いて詳細に説明する。先ず、準備工程として、予め第１のクランプ２１を相対的に開いた状態で、第１搬送機構３３により、線状体製造装置１１のセンターラインから図２のＲ方向に第１端子圧着機２９側へ所定距離移動させた状態で、線状体Ｗをその先端が第２のクランプ２３を越える所定位置まで線状体送出機１３により送り出し、第１のクランプ２１を相対的に閉じて線状体Ｗを把持しておく。
【００２５】
次に、線状体加工処理機１７のカッター部材１９を相対的に開くと共に、第２のクランプ２３を、図３（ａ）に示すように、相対的に開いた状態で、第２搬送機構３５により図２のＰＱ、ＳＲ方向に移動させて、線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）に配置する。
【００２６】
次に、第１のクランプ２１を第１搬送機構３３により図２のＳ方向及びＰ方向に線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）まで移動させると共に、その移動過程で、線状体Ｗの第１のクランプ２１より前方に送り出された部分を、図３（ａ）の矢印で示す方向に移動させて、第２のクランプ２３の相対的に開いたクランプ部材２５間のほぼ中央（中心）位置まで横方向から挿入する。
【００２７】
次に、第２のクランプ２３のクランプ部材２５を、図３（ｂ）に示すように、駆動機構の半閉作動により、線状体Ｗに対して押圧しないがクランプ部材２５の領域内に閉じ込める半閉姿勢に保持する共に、第１のクランプ２１のクランプ部材２２を前記線状体Ｗを把持した状態から、前記クランプ部材２５と同様な半閉姿勢に保持する状態にする。
【００２８】
次に、線状体Ｗを線状体送出機１３により送り出して走行させ、第１のクランプ２１、線状体加工処理機１７及び第２のクランプ２３に順次通過させる。なお、第１のクランプ２１のクランプ部材２２も線状体Ｗを通過させる間、半閉姿勢に保持させることが望ましいが、線状体送出機１３の近くに配設されているので、線状体Ｗの曲がり状態によっては、半閉姿勢に保持しなくてもよい。
【００２９】
次に、前記線状体Ｗを第１のクランプ２１、線状体加工処理機１７及び第２のクランプ２３に順次通過させる過程で、第１のクランプ２１を第１搬送機構３３により線状体加工処理機１７から走行する線状体Ｗの上流側（Ｑ方向）に、線状体Ｗの長手方向に沿って、線状体Ｗの被覆剥取り長、端子圧着、送り込み余裕長等を考慮して所定距離離反させた離反位置（図２の実線で示すＹ位置）まで移動させる。線状体送出機１３から送り出された線状体Ｗの送り出し長さが所定長に達したとき、測長機構１５からの指令で線状体送出機１３の運転、即ち、線状体Ｗの送り出しを停止する。
【００３０】
次に、第１、第２のクランプ２１、２３のクランプ部材２２、２５を相対的に閉じて線状体Ｗを把持し（図１、図３（ｃ）参照）、その後、図４（ａ）（ｂ）に示すように、線状体加工処理機１７のカッター部材１９を駆動機構の閉作動により相対的に閉じ、中央位置にある切断刃１９ａで線状体Ｗを切断する。
【００３１】
次に、線状体加工処理機１７のカッター部材１９を駆動機構の開作動により相対的に開き、切断された前方の線状体Ｗを把持した状態の第２のクランプ２３を第２搬送機構３５により図２のＳ方向に線状体取出機３７まで搬送し、第２のクランプ２３のクランプ部材２５を開いて該線状体Ｗを第２のクランプ２３より排出する。その後、第２のクランプ２３を、図３（ａ）に示すように、相対的に開いた状態で、第２搬送機構３５により図２のＲ方向に移動させて、線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）に配置し、次に動作に備える。
【００３２】
一方、後方の線状体Ｗを把持した状態の第１のクランプ２１を線状体送出機１３と共に、第１搬送機構３３により図２、図５（ａ）のＲ方向に所定距離横移動させ、図５（ａ）（ｂ）に示すように、線状体Ｗの切断端末がカッター部材１９の右側位置にある被覆剥取刃１９ｂに対向した位置で停止させる。
【００３３】
次に、第１のクランプ２１を第１搬送機構３３により、図２、図５（ａ）のＰ方向に破線で示すように線状体Ｗの被覆剥取り長に相当する距離移動させ、線状体Ｗの切断端末を線状体加工処理機１７のカッター部材１９の被覆剥取刃１９ｂ間の隙間に通過させる。
【００３４】
次に、線状体加工処理機１７のカッター部材１９を駆動機構の閉作動により相対的に閉じて図の右側位置にある被覆剥取刃１９ｂを線状体Ｗの切断端末の被覆に食い込ませ、このような被覆剥取刃１９ｂの食い込み状態のまま、第１のクランプ２１を第１搬送機構３３により、前記と逆方向であるＱ方向に移動させて元の位置まで戻す過程で、前記切断端末の被覆を被覆剥取刃１９ｂにより剥取り処理する。
【００３５】
次に、第１端子圧着機２９で後方の線状体Ｗの被覆が剥ぎ取られた切断端末に端子２７を圧着して接続する。その後、該端子２７が接続された線状体Ｗを把持した状態の第１のクランプ２１を、第１搬送機構３３により、図２のＳ方向及びＰ方向に線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）まで移動させる。その移動過程で、線状体Ｗの第１のクランプ２１より前方に送り出された部分を、図３（ａ）の矢印で示す方向に移動させて、第２のクランプ２３の相対的に開いたクランプ部材２５間のほぼ中央（中心）位置まで、前記端子２７がクランプ部材２５の前方（図２のＰ方向）に張り出すようにして横方向から挿入する。
【００３６】
次に、第２のクランプ２３のクランプ部材２５を、図３（ｂ）に示すように、駆動機構の半閉作動により、線状体Ｗに対して押圧しないがクランプ部材２５の領域内に閉じ込める半閉姿勢に保持する共に、第１のクランプ２１のクランプ部材２２を前記線状体Ｗを把持した状態から、前記クランプ部材２５と同様な半閉姿勢に保持する状態にする。
【００３７】
次に、線状体Ｗを線状体送出機１３により送り出して走行させ、第１のクランプ２１、線状体加工処理機１７及び第２のクランプ２３に順次通過させる。その通過過程で、第１のクランプ２１を第１搬送機構３３により線状体加工処理機１７から走行する線状体Ｗの上流側（Ｑ方向）に、また、第２のクランプ２３を第２搬送機構３５により線状体加工処理機１７から走行する線状体Ｗの下流側（Ｐ方向）に、それぞれ線状体Ｗの長手方向に沿って前記所定距離離反させた離反位置（図２の実線で示すＹ位置）まで移動させる。線状体送出機１３から送り出された線状体Ｗの送り出し長さが所定長に達したとき、測長機構１５からの指令で線状体送出機１３の運転、即ち、線状体Ｗの送り出しを停止する。
【００３８】
次に、第１、第２のクランプ２１、２３のクランプ部材２２、２５を相対的に閉じて線状体Ｗを把持し（図１、図３（ｃ）参照）、その後、図４（ａ）（ｂ）に示すように、線状体加工処理機１７のカッター部材１９を駆動機構の閉作動により相対的に閉じ、中央位置にある切断刃１９ａで線状体Ｗを切断する。
【００３９】
次に、線状体加工処理機１７のカッター部材１９を駆動機構の開作動により相対的に開き、切断された後方の線状体Ｗを把持した状態の第１のクランプ２１を線状体送出機１３と共に、第１搬送機構３３により図２、図５（ａ）のＲ方向に所定距離横移動させると共に、切断された前方の線状体Ｗを把持した状態の第２のクランプ２３を第２搬送機構３５により図２、図５（ａ）のＳ方向に、即ち、第１のクランプ２１の移動方向と反対方向に、所定距離横移動させ、図５（ａ）（ｂ）に示すように、前後方の線状体Ｗの各切断端末がカッター部材１９の両側位置にある被覆剥取刃１９ｂに対向した位置で停止させる。
【００４０】
次に、第１のクランプ２１を第１搬送機構３３により、図２、図５（ａ）のＰ方向に破線で示すように線状体Ｗの被覆剥取り長に相当する距離移動させ、線状体Ｗの切断端末を線状体加工処理機１７のカッター部材１９の被覆剥取刃１９ｂ間の隙間に通過させると共に、第２のクランプ２３を第２搬送機構３５により、図２、図５（ａ）のＱ方向に破線で示すように線状体Ｗの被覆剥取り長に相当する距離移動させ、線状体Ｗの切断端末を線状体加工処理機１７のカッター部材１９の被覆剥取刃１９ｂ間の隙間に通過させる。
【００４１】
次に、線状体加工処理機１７のカッター部材１９を駆動機構の閉作動により相対的に閉じて両側位置にある被覆剥取刃１９ｂを線状体Ｗの各切断端末の被覆に食い込ませ、このような被覆剥取刃１９ｂの食い込み状態のまま、第１、第２のクランプ２１、２３を第１、第２搬送機構３３、３５により、前記と逆方向であるＱＰ方向に移動させて元の位置まで戻す過程で、各切断端末の被覆を被覆剥取刃１９ｂにより剥取り処理する。
【００４２】
次に、線状体加工処理機１７のカッター部材１９を駆動機構の開作動により相対的に開き、後方の線状体Ｗを把持した状態の第１のクランプ２１を線状体送出機１３と共に、第１搬送機構３３により図２のＲ方向に第１端子圧着機２９まで横移動させると共に、前方の線状体Ｗを把持した状態の第２のクランプ２３を第２搬送機構３５により図２のＳ方向に、即ち、第１のクランプ２１の移動方向と反対方向に、第２端子圧着機３１まで横移動させて停止する。
【００４３】
次に、第１端子圧着機２９で後方の線状体Ｗの被覆が剥ぎ取られた前方切断端末に端子２７を圧着して接続すると共に、第２端子圧着機３１で前方の線状体Ｗの被覆が剥ぎ取られた後方切断端末に端子２７を圧着して接続する。
【００４４】
このようにして第２端子圧着機３１で前後方切断端末に端子２７が接続された加工処理済みの線状体Ｗを、第２搬送機構３５により線状体取出機３７まで搬送し、線状体取出機３７で取り出してストックヤードに収納するか、又は、コンベアで次の工程装置に搬送する。その後、第２のクランプ２３を、図３（ａ）に示すように、相対的に開いた状態で、第２搬送機構３５により図２のＲ方向に移動させて、線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）に配置し、次に動作に備える。
【００４５】
一方、該端子２７が接続された線状体Ｗを把持した状態の第１のクランプ２１を、第１搬送機構３３により、図２のＳ方向及びＰ方向に線状体製造装置１１のセンターライン上で、線状体加工処理機１７の近傍位置（図２の破線で示すＸ位置）まで移動させる。その移動過程で、線状体Ｗの第１のクランプ２１より前方に送り出された部分を、図３（ａ）の矢印で示す方向に移動させて、第２のクランプ２３の相対的に開いたクランプ部材２５間のほぼ中央（中心）位置まで、前記端子２７がクランプ部材２５の前方（図２のＰ方向）に張り出すようにして横方向から挿入する。
【００４６】
次に、第２のクランプ２３のクランプ部材２５を、図３（ｂ）に示すように、駆動機構の半閉作動により、線状体Ｗに対して押圧しないがクランプ部材２５の領域内に閉じ込める半閉姿勢に保持する共に、第１のクランプ２１のクランプ部材２２を前記線状体Ｗを把持した状態から、前記クランプ部材２５と同様な半閉姿勢に保持する状態にし、線状体Ｗを線状体送出機１３により送り出して走行させ、第１のクランプ２１、線状体加工処理機１７及び第２のクランプ２３に順次通過させ、以後前記した線状体Ｗの加工処理作業を繰り返し、所定長の線状体Ｗを製造する。
【００４７】
前記したように、本発明の線状体製造方法では、少なくとも第２のクランプ２３のクランプ部材２５を、線状体Ｗに対して押圧しないがクランプ部材２５の領域内に閉じ込める半閉姿勢にして、線状体Ｗを第１、第２のクランプ２１、２３内に通過させるようにしたので、線状体Ｗが少なくとも第２のクランプ２３を通過する際、うねったり、蛇行したり等して曲がっていても、半閉姿勢に保持して線状体Ｗとの隙間が狭くなった少なくとも第２のクランプ２３のクランプ部材２５によって曲がりを矯正され、線状体Ｗが少なくとも第２のクランプ２３の前記クランプエリアＡから外れることがなくなる。
【００４８】

BACKGROUND OF THE INVENTION
The present invention relates to a linear body manufacturing method and a linear body manufacturing apparatus for processing and manufacturing a linear body having flexibility.
[0002]
[Prior art]
A linear body manufacturing method for manufacturing a flexible long linear body such as an electric wire, tube, hose, etc. by subjecting it to processing such as cutting, stripping, surface treatment, mounting of a connecting member such as a terminal, etc. Is usually performed using a linear body manufacturing apparatus 10 as shown in FIG.
[0003]
The manufacturing apparatus 10 includes, for example, a length measuring mechanism 2, a linear body sending machine 1 such as an endless track type that intermittently feeds the linear body W every predetermined length, and a driving mechanism (not shown). ), And a linear body processing machine 3 for cutting the linear body W at predetermined lengths, and a linear body entrance of the linear body processing machine 3. A first clamp 5 having a pair of clamp members 7 that are opened and closed by a drive mechanism (not shown) and a linear body outlet side of the linear body processing machine 3, And a second clamp 6 having a pair of clamp members 7 that are relatively opened and closed by a drive mechanism (not shown) (see FIGS. 7A and 7B).
[0004]
The conventional linear body manufacturing method will be described using the manufacturing apparatus 10. First, the linear body W that is intermittently delivered by the linear body delivery machine 1 every predetermined length is first opened with the clamp member 7 opened. The clamp 5 (see FIG. 7A), the linear body processing machine 3 with the cutter member 4 opened (see FIG. 6), and the second clamp 6 with the clamp member 7 opened (see FIG. 7A). Let it pass. Next, when the linear body W is sent out for a predetermined length, the operation of the linear body transmitter 1, that is, the delivery of the linear body W is stopped by a command from the length measuring mechanism 2. Next, the clamp members 7 of the first and second clamps 5 and 6 are closed by the closing operation of the drive mechanism to grip the linear body W (see FIG. 7B). Next, the cutter member 4 of the linear body processing machine 3 is closed by the closing operation of the drive mechanism, the linear body W is cut, and the linear body W is processed. Thereafter, for example, if necessary, the outer peripheral surface of the cutting terminal is peeled off, and the terminal is attached by crimping or the like (see Patent Document 1).

[Patent Document 1]
Japanese Patent Laid-Open No. 7-45351 (paragraph 0002 and FIG. 10 of the detailed description of the invention)
[0006]
[Problems to be solved by the invention]
When the linear body W is manufactured by being processed by the linear body processing machine 3, the linear body W passes through the clamp member 7 having the first and second clamps 5 and 6 opened in advance for a predetermined length. Then, the clamp member 7 needs to be closed and gripped so that the linear body W does not move during the processing of the linear body W.
[0007]
By the way, the linear body W is generally flexible, and when it is wound around a drum, a reel, etc., it is easy to bend, so the linear body W is sent out from the linear body feeder 1. When the linear body W is supplied to the linear body processing machine 3, the traveling linear body W does not become straight due to undulation or meandering, and as the linear body W travels downstream, The axis tends to deviate from the center line of the linear body manufacturing apparatus.
[0008]
In particular, when passing the linear body W between the clamp members 7 of the second clamp 6 provided on the downstream side of the linear body processing machine 3, the linear body W is indicated by a clamp area A indicated by a broken line (FIG. 7). (Refer to (a) and (b)) It is easy to come off from the inside, and in the worst case, it may protrude from the clamp member 7, and the gripping failure (clamping error) of the linear body W occurs, and the linear body W is surely May not be able to be gripped. For this reason, there existed a problem that the yield and quality of the linear body W manufactured by processing and the processing efficiency of a linear body fall.
[0009]
The present invention solves the above-mentioned problems, and when the linear body is processed and manufactured, the linear body is securely gripped by preventing the linear body from being poorly gripped. It is an object of the present invention to provide a linear body manufacturing method and a linear body manufacturing apparatus capable of improving the yield and quality of a linear body manufactured by processing.
[0010]
[Means for Solving the Problems]
  In order to achieve the above object, according to the first aspect of the present invention, there is provided a clamp member for holding the linear body on the linear body inlet side and the linear body outlet side of the linear body processing machine. A first clamp and a second clamp are provided, and the linear body is allowed to pass through the first clamp, the linear body processing machine, and the second clamp for a predetermined length, and clamp members of the first and second clamps are provided. In the linear body manufacturing method in which the linear body is processed by the linear body processing machine after the linear body is gripped and the linear body is processed, at least the clamp member of the second clamp is not pressed against the linear body. In a semi-closed position confined in the region of the clamp member, and let the linear body pass through the first and second clamps.After that, when processing a plurality of linear bodies, place the clamp on the side to be processed at least before passing the linear body through it, and place it near the linear body processing machine and pass through the linear body Or the distance between the end of the passage and the time when the linear body is gripped from the linear body processing machine along the longitudinal direction of the linear body.It is characterized by that.
[0011]
  In this way, at least the clamp member of the second clamp is not pressed against the linear body, but is in a semi-closed posture confined in the region of the clamp member, and the linear body passes through the first and second clamps. If you letWhen the linear body passes through the clamp, even if it is bent due to undulation or meandering, the bending is corrected by the clamp member of the clamp that is held in a semi-closed posture and the gap between the linear body is narrowed. , The linear body will not come off from the clamp area of the clamp. Therefore, when the clamp member of the clamp is closed, there is no gripping failure (clamping error) of the linear body, the linear body can be securely gripped, and the processing efficiency of the linear body is improved. The yield and quality of the manufactured linear body W can be improved.
[0013]
  In addition, when processing a plurality of linear bodies, at least a clamp on the side to be post-processed is disposed in the vicinity of the linear body processing machine before passing the linear bodies therethrough, and the linear bodies are allowed to pass through. In the process or after the end of passing, until the linear body is gripped, it is separated from the linear body processing machine by a predetermined distance along the longitudinal direction of the linear body.Then, since the distance between the first and second clamps is shortened, the axis of the linear body is not excessively deviated from the center line of the linear body manufacturing apparatus, and the linear body can be It becomes easy to put it in the clamp 2 and grip it, and the gripping failure of the linear body can be reduced.
[0014]
In addition, when a plurality of linear bodies are processed, if the post-processing is performed by moving the linear bodies in the longitudinal direction, the processing is performed after the pre-processing process is completed and the linear body is post-processed. It can be performed by moving in the longitudinal direction while being held by the clamp, and the work efficiency of the linear body processing can be further improved.
[0015]
  Claims of the invention2The invention described in 1 is provided with a first clamp and a second clamp having a clamp member for gripping the linear body on the linear body inlet side and the linear body outlet side of the linear body processing machine, In the linear body manufacturing apparatus in which the linear body is gripped by the first and second clamps and processed by the linear body processing machine, at least the second clamp has the clamp member as the linear body. The structure is held in a semi-closed posture that is not pressed against but is confined in the region of the clamp member,In addition, when processing a plurality of linear bodies, at least a clamp on the side to be post-processed is disposed in the vicinity of the linear body processing machine before passing the linear bodies therethrough, and the linear bodies are allowed to pass through. Provided with a transport mechanism that separates a predetermined distance along the longitudinal direction of the linear body from the linear body processing machine during the process or after the passage is finished and until the linear body is grippedIt is characterized by that.
[0016]
  According to such a configuration, since it is not necessary to use a complicated mechanism for correcting the bending of the linear body, the structure of the apparatus is simplified, and the apparatus can be manufactured or modified at low cost without trouble. In addition to being able to reliably prevent poor gripping of the linear body, it can be manufactured by efficiently processing the linear body.In addition, since the conveyance mechanism for separating the linear body from the linear body processing machine by a predetermined distance along the longitudinal direction of the linear body is provided, the processing operation of the linear body can be further improved.

Next, the linear body W is sent out by the linear body sending machine 13 and travels, and is sequentially passed through the first clamp 21, the linear body processing machine 17, and the second clamp 23. During the passage process, the first clamp 21 is moved upstream of the linear body W traveling in the Q direction by the first transport mechanism 33 from the linear body processing machine 17 (Q direction), and the second clamp 23 is A separation position (in FIG. 2) that is separated from the linear body W traveling from the linear body processing machine 17 on the downstream side (P direction) by the transport mechanism 35 along the longitudinal direction of the linear body W. (Y position indicated by a solid line). When the delivery length of the linear body W delivered from the linear body delivery machine 13 reaches a predetermined length, the operation of the linear body delivery machine 13 according to a command from the length measuring mechanism 15, i.e., the Stop sending.
[0038]
Next, the clamp members 22 and 25 of the first and second clamps 21 and 23 are relatively closed, and the linear body W is gripped (see FIGS. 1 and 3C), and thereafter, FIG. (B) As shown in (b), the cutter member 19 of the linear body processing machine 17 is relatively closed by the closing operation of the drive mechanism, and the linear body W is cut by the cutting blade 19a at the center position.
[0039]
Next, the cutter member 19 of the linear body processing machine 17 is relatively opened by the opening operation of the drive mechanism, and the first clamp 21 in a state in which the cut rear linear body W is gripped is delivered to the linear body. Together with the machine 13, the first transport mechanism 33 moves the second clamp 23 in the state of holding the cut front linear body W in the R direction in FIGS. 2 is moved laterally by a predetermined distance in the S direction in FIGS. 2 and 5A, that is, in the direction opposite to the moving direction of the first clamp 21, by the transport mechanism 35, as shown in FIGS. 5A and 5B. In addition, the cutting terminals of the front and rear linear bodies W are stopped at positions facing the coating stripping blades 19 b at both side positions of the cutter member 19.
[0040]
Next, the first clamp 21 is moved by the first transport mechanism 33 by a distance corresponding to the coating stripping length of the linear body W in the P direction in FIGS. 2 and 5A as indicated by a broken line. The cutting end of the rod W is passed through the gap between the coating stripping blades 19b of the cutter member 19 of the linear body processing machine 17, and the second clamp 23 is moved by the second transport mechanism 35 in FIGS. As indicated by a broken line in the Q direction of (a), the distance corresponding to the coating stripping length of the linear body W is moved, and the cutting end of the linear body W is stripped of the cutter member 19 of the linear body processing machine 17. It passes through the gap between the blades 19b.
[0041]
Next, the cutter member 19 of the linear body processing machine 17 is relatively closed by the closing operation of the drive mechanism, and the coating stripping blades 19b at both side positions are bitten into the coating of each cutting terminal of the linear body W, The first and second clamps 21 and 23 are moved in the QP direction opposite to the above by the first and second transport mechanisms 33 and 35 while the covering stripping blade 19b is in the biting state. In the process of returning to the position, the coating of each cutting terminal is stripped by the coating stripping blade 19b.
[0042]
Next, the cutter member 19 of the linear body processing machine 17 is relatively opened by the opening operation of the drive mechanism, and the first clamp 21 in a state where the rear linear body W is gripped together with the linear body feeder 13. 2, the second clamp 23 in a state of gripping the front linear body W is moved by the second transport mechanism 35 in FIG. In the S direction, that is, in the direction opposite to the moving direction of the first clamp 21, it is moved laterally to the second terminal crimping machine 31 and stopped.
[0043]
Next, the terminal 27 is crimped and connected to the front cutting terminal from which the coating of the rear linear body W has been removed by the first terminal crimping machine 29, and the front linear body W is connected by the second terminal crimping machine 31. The terminal 27 is crimped and connected to the rear cutting terminal from which the coating has been removed.
[0044]
In this way, the processed linear body W in which the terminal 27 is connected to the front / rear cutting terminal by the second terminal crimping machine 31 is transported to the linear body take-out machine 37 by the second transport mechanism 35, It is taken out by the body take-out machine 37 and stored in the stock yard, or it is conveyed to the next process apparatus by the conveyor. Thereafter, the second clamp 23 is moved in the R direction in FIG. 2 by the second transport mechanism 35 in a relatively opened state as shown in FIG. It arrange | positions on the center line in the vicinity position (X position shown with the broken line of FIG. 2) of the linear body processing machine 17, and prepares for operation | movement next.
[0045]
On the other hand, the first clamp 21 in a state where the linear body W to which the terminal 27 is connected is gripped by the first transport mechanism 33 in the S direction and the P direction of FIG. Above, it moves to the position (X position shown with the broken line of FIG. 2) of the vicinity of the linear body processing machine 17. FIG. In the moving process, the portion fed forward from the first clamp 21 of the linear body W is moved in the direction indicated by the arrow in FIG. The terminal 27 is inserted from the lateral direction so as to protrude forward (P direction in FIG. 2) of the clamp member 25 to a substantially central (center) position between the clamp members 25.
[0046]
Next, as shown in FIG. 3B, the clamp member 25 of the second clamp 23 is not pressed against the linear body W by the semi-closed operation of the drive mechanism, but is confined within the region of the clamp member 25. While maintaining the semi-closed posture, the clamp member 22 of the first clamp 21 is changed from the state of gripping the linear body W to the semi-closed posture similar to the clamp member 25, and the linear body W is The linear body delivery machine 13 sends out and travels, and sequentially passes through the first clamp 21, the linear body processing machine 17 and the second clamp 23, and thereafter repeats the processing of the linear body W described above, A linear body W having a predetermined length is manufactured.
[0047]
As described above, in the linear body manufacturing method of the present invention, at least the clamp member 25 of the second clamp 23 is not pressed against the linear body W, but is in a semi-closed posture that is confined in the region of the clamp member 25. Since the linear body W is allowed to pass through the first and second clamps 21 and 23, the linear body W at least passes through the second clamp 23, so that it undulates, meanders, etc. Even if bent, the bending is corrected by at least the clamp member 25 of the second clamp 23 which is held in a semi-closed posture and the gap with the linear body W is narrowed, so that the linear body W is at least the second clamp 23. Of the clamp area A.
[0048]
Accordingly, when the clamp members 22 and 25 of the clamps 21 and 23 are closed, the gripping failure (clamping error) of the linear body W is eliminated, and the linear body W can be securely gripped. It is possible to improve the processing efficiency and the yield and quality of the linear body W manufactured by processing.
[0049]
In addition, as described above, when a plurality of linear bodies W are processed, the linear bodies before the first and second clamps 21 and 23 on the side to be post-processed are passed through the linear bodies W. It may be arranged in the vicinity of the processing machine 17 and separated from the linear body processing machine 17 by a predetermined distance along the longitudinal direction of the linear body W in the process of passing the linear body W.
[0050]
If it does in this way, since the distance between the 1st, 2nd clamps 21 and 23 becomes short, the axis line of the linear body W does not shift | deviate excessively from the centerline of a linear body manufacturing apparatus, and it is linear. It becomes easy to put the body W in the first and second clamps 21 and 23 and grip it, and the gripping failure of the linear body W can be reduced.
[0051]
Further, when a plurality of processings are performed on the linear body W, for example, when the cutting and stripping processing is performed as described above, the post-processing (coating stripping) moves the linear body W in the longitudinal direction. In the case of performing the processing, after the preprocessing (cutting processing) is completed, the linear body W is moved in the longitudinal direction while being gripped by the first and second clamps 21 and 23 on the postprocessing side. Thus, the work efficiency of the processing of the linear body W can be further improved.
[0052]
In the above-described embodiment, at least the clamps on the side to be post-processed, that is, the first and second clamps 21 and 23 are arranged in the vicinity of the linear body processing machine 17 before passing the linear body W therethrough. In the course of passing the linear body W, the linear body processing machine 17 is separated from the linear body W by a predetermined distance along the longitudinal direction of the linear body W, but the linear body W passes through the clamps 21 and 23. After completion, the linear body W is separated from the linear body processing machine 17 by a predetermined distance along the longitudinal direction of the linear body W until the linear body W is gripped by the first and second clamps 21 and 23. May be. Further, the clamp on the side not to be post-processed may be separated from the linear body processing machine 17 by a predetermined distance along the longitudinal direction of the linear body W.
[0053]
Furthermore, in the said embodiment, when inserting the linear body W between the clamp members 25 of the 2nd clamp 23, as shown to Fig.3 (a), it is perpendicular | vertical with respect to the center line of the linear body manufacturing apparatus 11. FIG. In this case, it is inserted from the lateral direction, but may be inserted from the direction along the center line of the linear body manufacturing apparatus 11. When the linear body W is inserted from the lateral direction as in the above-described embodiment, even if a projection such as the terminal 27 is provided at the end of the linear body W, the projection is clamped 25. This is preferable because it can be inserted at a position where it does not hit, and the insertion becomes easy. Further, as described above, only the second clamp 23 may be configured to hold the clamp member 25 in a semi-closed posture in which the clamp member 25 is not pressed against the linear body W but is confined in the region of the clamp member 25. .
[0054]
In addition, although the above-mentioned linear body manufacturing method is an example of the cutting | disconnection of a rubber | gum and a plastic insulated wire (a cable is included), coating | cover stripping, and a terminal crimping method, it is not limited only to this, Rubber | gum, plastic Cutting of metal hoses, tubes, optical fibers and other flexible linear bodies, stripping of coatings, chamfering, grooving, terminal diameter expansion, diameter reduction, thread cutting, inner and outer surface grinding, polishing, painting, terminal fitting installation It can be applied to single or multiple tasks such as.
[0055]

Since the linear body is passed through the first and second clamps in a semi-closed posture, when the linear body passes through the clamp, even if it is bent, such as wavy or meandering, The bending is corrected by the clamp member of the clamp which is held in the semi-closed posture and the gap with the linear body is narrowed, and the linear body is not detached from the clamp area of the clamp. Therefore, when the clamp member of the clamp is closed, there is no gripping failure (clamping error) of the linear body, the linear body can be securely gripped, and the processing efficiency of the linear body is improved. The yield and quality of the manufactured linear body W can be improved.

As a result, the distance between the first and second clamps is shortened, and the axis of the linear body is not excessively deviated from the center line of the linear body manufacturing apparatus. It becomes easy to put in the second clamp and grip it, and the gripping failure of the linear body can be reduced.
[0057]
