Description

電線端末処理装置の電線反転機構Electric wire reversing mechanism of electric wire terminal processing equipment
　本発明は、電線の前端部分および後端部分をそれぞれストリップして端子を圧着する電線端末処理を実行する際に、電線の前端部分を保持して旋回させることにより電線をＵ字形に反転させる機構に関し、より詳しくは、電線反転装置を備えていない既存の電線端末処理装置にも後から取付可能な構造の電線反転機構に関する。 The present invention is a mechanism for reversing an electric wire into a U-shape by holding and turning the front end portion of the electric wire when performing the electric wire end processing for stripping the front end portion and the rear end portion of the electric wire and crimping the terminal. More particularly, the present invention relates to an electric wire reversing mechanism having a structure that can be attached later to an existing electric wire terminal processing device that does not include the electric wire reversing device.
　従来、電線を所定の長さに切断するとともに、切断した電線の前後の端末部分の絶縁被覆をそれぞれストリップして芯線を露出させ、次いで露出させた芯線に端子を圧着する作業を行う電線処理装置が用いられている（例えば、下記特許文献１を参照）。 Conventionally, an electric wire processing apparatus that cuts an electric wire to a predetermined length, strips the insulating coating on the front and rear ends of the cut electric wire, exposes the core wire, and then crimps the terminal to the exposed core wire Is used (see, for example, Patent Document 1 below).
　その構造について図１４を参照しつつ概説すると、この電線端末処理装置は、電線Ｗ０を測長しながら前方に送給する測長供給手段１と、所定の長さに送給された電線Ｗを切断する切断手段２と、切断された電線Ｗ０の前端部分をストリップする第１のストリップ手段３と、露出した芯線に端子Ｃ１を圧着する第１の端子圧着手段４とを備えている。
　また、この電線処理装置は、所定の長さに切断された電線Ｗ１の後端部分をストリップする第２のストリップ手段５と、露出した芯線に端子Ｃ２を圧着する第２の端子圧着手段６と、電線Ｗ１の後端部分を保持する保持手段７と、完成した電線Ｗ２を排出する排出手段８と、これらの手段５，６，７，８の間で電線Ｗ１の後端部分を把持して搬送する搬送手段９とを備えている。 The outline of the structure will be described with reference to FIG. 14. This wire terminal processing apparatus includes a length measuring means 1 for feeding the wire W0 forward while measuring the length of the wire W0, and a wire W fed to a predetermined length. A cutting means 2 for cutting, a first strip means 3 for stripping the front end portion of the cut electric wire W0, and a first terminal crimping means 4 for crimping the terminal C1 to the exposed core wire are provided.
The electric wire processing apparatus also includes a second strip means 5 for stripping the rear end portion of the electric wire W1 cut to a predetermined length, and a second terminal crimping means 6 for crimping the terminal C2 to the exposed core wire. The holding means 7 for holding the rear end portion of the electric wire W1, the discharge means 8 for discharging the completed electric wire W2, and the rear end portion of the electric wire W1 are held between these means 5, 6, 7, and 8. And a conveying means 9 for conveying.
　ところで、上述した電線端末処理装置においては、完成させる電線Ｗ２の全長が長くなるに連れ、搬送手段９による電線Ｗ２の搬送が次第に困難になる。
　そこで、所定の長さの電線をＵ字形に反転させて、その前端部分と後端部分とを隣接させた状態で一体に保持するとともに、電線端末処理装置の一側に並設したストリップ手段および端子圧着手段によって、電線の前端部分および後端部分を順次処理する構造の電線端末処理装置が開発されている（記特許文献２を参照）。 By the way, in the electric wire terminal processing apparatus mentioned above, conveyance of the electric wire W2 by the conveyance means 9 becomes difficult gradually as the full length of the electric wire W2 to be completed becomes long.
Therefore, by reversing the electric wire having a predetermined length into a U-shape and holding the front end portion and the rear end portion adjacent to each other, strip means arranged side by side on one side of the electric wire terminal processing device, and An electric wire terminal processing apparatus having a structure in which a front end portion and a rear end portion of an electric wire are sequentially processed by terminal crimping means has been developed (see Patent Document 2).
　このとき、電線をＵ字形に反転させるために、エアシリンダの伸縮によって揺動するアームから吊り下げられた電線クランプを用いる電線反転機構が提案されている（下記特許文献３を参照）。 At this time, a wire reversing mechanism using a wire clamp suspended from an arm that swings by expansion and contraction of an air cylinder has been proposed in order to reverse the wire into a U shape (see Patent Document 3 below).
　また、電線をＵ字形に反転させるために、上下方向に延びる回動軸に取り付けられて１８０度旋回するアームと、このアームの揺動端に設けられたクランプを用いる電線反転機構がある（下記特許文献４を参照）。 In addition, there is an electric wire reversing mechanism using an arm attached to a pivot shaft extending in the vertical direction and turning 180 degrees and a clamp provided at the swinging end of the arm in order to reverse the electric wire into a U shape (see below). (See Patent Document 4).

　ところで、図１４に示したような、電線反転機構を備えていない電線端末処理装置を用いている製造現場においては、製造する電線の全長の変更に伴い、電線をＵ字形に反転させた状態での電線端末処理が必要となる場合がある。
　しかしながら、既存の電線端末処理装置に電線反転機構を追加するためには、ストリップ手段や端子圧着手段の位置を変更したり、搬送手段を改造したりする必要がある。
　これにより、既存の電線端末処理装置に電線反転機構を後から追加することは極めて困難であった。
　また、特許文献４の図２、図３に示した状態で電線は、前側端子が圧着された状態で、電線測長送給手段により所定の長さだけ前方に送給され、その前側部分が電線湾曲手段の電線把持部によって把持され、回動軸の回りに１８０°回動して電線は、Ｕ字形に湾曲される。
　しかし、電線送給時に電線にねじれがあるため、前側端子は、圧着された時点の姿勢を保持することができず、どうしても端子は、ローリングしてしまうことがあった。
電線端末処理装置上で、電線圧着の状態をカメラを用いた画像で確認する必要がある場合など、端子がローリングしていると画像確認ができないという不具合が発生していた。 By the way, in the manufacturing site which uses the electric wire terminal processing apparatus which is not provided with the electric wire reversing mechanism as shown in FIG. 14, with the change of the full length of the electric wire to manufacture, in the state which reversed the electric wire into the U-shape. It may be necessary to process the end of the wire.
However, in order to add an electric wire reversing mechanism to an existing electric wire terminal processing apparatus, it is necessary to change the positions of the strip means and the terminal crimping means or to modify the conveying means.
As a result, it has been extremely difficult to add an electric wire reversing mechanism to an existing electric wire terminal processing apparatus later.
Further, in the state shown in FIGS. 2 and 3 of Patent Document 4, the electric wire is fed forward by a predetermined length by the electric wire length measuring and feeding means in a state where the front terminal is crimped, and the front portion thereof is The electric wire is bent by the electric wire holding portion of the electric wire bending means, and rotated by 180 ° around the rotation axis, so that the electric wire is bent into a U shape.
However, since the electric wire is twisted when the electric wire is fed, the front terminal cannot maintain the posture at the time of being crimped, and the terminal may roll by all means.
In the case where it is necessary to confirm the state of wire crimping with an image using a camera on the wire terminal processing apparatus, there has been a problem that the image cannot be confirmed when the terminal is rolling.
　そこで本発明の目的は、上述した従来技術が有する問題点を解消し、電線をＵ字形に反転させた状態でも端子が圧着された時点の姿勢が保持できるとともに、端子電線反転機構を備えていない既存の電線端末処理装置にも後付け可能な、小型でかつ高速作動が可能な構造の電線反転機構を提供することにある。 Therefore, the object of the present invention is to solve the above-mentioned problems of the prior art, maintain the posture when the terminal is crimped even in a state where the electric wire is inverted into a U shape, and does not have a terminal electric wire reversing mechanism. An object of the present invention is to provide a wire reversing mechanism having a small size and capable of high-speed operation that can be retrofitted to an existing wire terminal processing apparatus.

　これにより、Ｕ字形に延びる所定の軌道のうち、円弧状に湾曲する部分の半径を小さくせざるを得ない場合にも、容易に対応することができる。
　また、Ｕ字形に反転させる電線の前端部分を電線把持手段が把持するときの前後方向の位置は、一対のプーリに巻回されて長円状に延びるベルトのうち直線状に延びる部分の任意の位置に設定することができるから、既存の電線端末処理装置の構造に合わせて自在に調整することができる。 Moreover, the electric wire reversing mechanism of the electric wire terminal processing apparatus by this invention is a structure which drives an electric wire holding means with the belt wound around a pair of pulleys.
Thereby, it is possible to easily cope with the case where the radius of the arcuately curved portion of the predetermined trajectory extending in the U shape has to be reduced.
In addition, the position in the front-rear direction when the wire gripping means grips the front end portion of the electric wire to be reversed into a U-shape is an arbitrary portion of the linearly extending portion of the belt that is wound around the pair of pulleys and extends in an oval shape. Since it can set to a position, it can adjust freely according to the structure of the existing electric wire terminal processing apparatus.
　本発明によれば、既存の電線端末処理装置に後付け可能な構造でありながら、電線の前端部分を正確に案内しつつ移動させて電線をＵ字形に反転させることができ、さらには小型でかつ電線をＵ字形に反転させる動作を高速に実行できる電線端末処理装置の電線反転機構を提供することができる。また電線把持手段が電線のうち前端側の端子直後の前端部分を把持して、旋回体と一体に旋回する。このため、電線をＵ字状に反転させた際でも、前端側の端子が圧着された姿勢を保持することができ、電線圧着の状態を端子がローリングすることなく、画像確認することができる。 According to the present invention, while being a structure that can be retrofitted to an existing wire terminal processing apparatus, the front end portion of the electric wire can be moved while being accurately guided, and the electric wire can be inverted into a U-shape, and further, the size and It is possible to provide an electric wire reversing mechanism of an electric wire terminal processing apparatus that can execute an operation of inverting an electric wire into a U shape at high speed. Further, the electric wire gripping means grips the front end portion immediately after the terminal on the front end side of the electric wire and turns together with the swivel body. For this reason, even when the electric wire is inverted in a U shape, the posture in which the terminal on the front end side is crimped can be maintained, and the state of the electric wire crimping can be confirmed without the terminal rolling.

　このとき、図示されない制御手段によって電動モータ１７を反時計方向に回動させると、電線把持手段３０の把持爪３２は、図１および図８に示した第１の位置に到着する。
　この第１の位置においては、把持爪３２の向きは、凹溝１４と一対のローラ２７ａ，２７ｂとの係合により、前方に延びている電線Ｗ１を左右方向に挟持可能な向きに規定されている。
　また、旋回体２３を支持している一対の棒状支持体２２ａ，２２ｂは、図７（ａ）に示したように回動体２１から一杯に延び出た状態となっている。 As shown in FIGS. 1 and 2, the crimping of the terminal C1 to the front end of the electric wire W0 is completed to obtain a semi-finished electric wire W1, and in a state where the terminal C1 faces the cutting means 2, The front end portion of the electric wire W1 is held by the holding portion 1a of the length measurement supply means 1.
At this time, when the electric motor 17 is rotated counterclockwise by a control means (not shown), the gripping claws 32 of the wire gripping means 30 arrive at the first position shown in FIGS.

Further, the pair of rod- like support bodies 22a and 22b supporting the revolving body 23 are in a state of being fully extended from the rotating body 21 as shown in FIG.
　次いで、電線把持手段３０のエアシリンダ３３を作動させて把持爪３２を降下させた後、エアシリンダ３４を作動させて把持爪３２を閉じると、前端部分は、保持部１ａによって保持されているので、端子Ｃ１の姿勢を保持したままの状態で把持爪３２によって図１のとおり、電線Ｗ１のうち前端側の端子Ｃ１直後の前端部分を把持することができる。
　次いで、電動モータ１７を時計方向に回動させると、電線把持手段３０の把持爪３２は、図１および図８に示した第２の位置に到着する。
　この場合、電線Ｗ１のうち前端側の端子Ｃ１直後の前端部分を把持することにより、電線Ｗ１がＵ字状に反転した場合であっても、端子Ｃ１が圧着された姿勢を保持することができ、電線圧着の状態の端子Ｃ１がローリングすることなく画像確認することができる。

In this case, by gripping the front end portion immediately after the terminal C1 on the front end side of the electric wire W1, even when the electric wire W1 is inverted in a U shape, the posture in which the terminal C1 is crimped can be maintained. The image can be confirmed without rolling the terminal C1 in the crimped state.
In this second position, the gripping claws 32 are oriented so that the rear end portion of the electric wire W1 gripped by the gripping claws 32 faces rearward due to the engagement of the concave groove 14 and the pair of rollers 27a and 27b.

A suitable distance is moved toward the second strip means 5, and the rear end portion is stripped by the second strip means 5.
　後端部分のストリップが完了すると、前端保持手段４４および後端保持手段４２は、図１における図示左方向に一体に移動し、電線Ｗ１の後端部分を第２の端子圧着手段６に対向させる。
　すると、電線Ｗ１の後端部分は、前端保持手段４４および後端保持手段４２が端子圧着手段６に向け、適宜な距離を移動し第２の端子圧着手段６による第２の端子Ｃ２の圧着が行われ、完成品の電線Ｗ２が得られる。 When the strip of the rear end portion is completed, the front end holding means 44 and the rear end holding means 42 move integrally in the left direction in FIG. 1 so that the rear end portion of the electric wire W1 faces the second terminal crimping means 6. .
Then, in the rear end portion of the electric wire W1, the front end holding means 44 and the rear end holding means 42 move toward the terminal crimping means 6 to move an appropriate distance so that the second terminal crimping means 6 can crimp the second terminal C2. As a result, a finished electric wire W2 is obtained.
　その後、完成品の電線Ｗ２は、前端保持手段４４および後端保持手段４２によって保持された状態で、図１における図示左方向に移動し、保持手段７および排出手段８を経由して電線端末処理装置１０の外部に排出される。 Thereafter, the finished electric wire W2 is moved in the left direction in FIG. 1 while being held by the front end holding means 44 and the rear end holding means 42, and is subjected to electric wire terminal processing via the holding means 7 and the discharge means 8.

　したがって、電線把持手段７０は、案内部材６５によって上下方向に支持されつつ、案内部材６５によって案内されて所定の軌道に沿って移動することができる。 In addition, rollers 73 a and 73 b that roll on the upper surface of the guide member 65 and the side surface on the inner peripheral side are rotatably supported on a portion of the arm 73 that faces the guide member 65.
Further, a roller support member 78 is fixed to the outer peripheral end of the arm 73.
The roller support member 78 rotatably supports rollers 78a and 78b that roll on the outer peripheral side surface and the lower surface of the guide member 65, respectively.
Thereby, the arm 73 of the electric wire gripping means 70 is engaged with the guide member 65 in the vertical direction and the horizontal direction (width direction) by the rollers (engagement means) 73a, 73b, 78a, 78b.
Accordingly, the wire gripping means 70 can be moved along a predetermined track while being guided by the guide member 65 while being supported by the guide member 65 in the vertical direction.
　次に、本第２実施形態の電線反転機構２００の作動について説明する。 Next, the operation of the electric wire reversing mechanism 200 according to the second embodiment will be described.
　図１に示したように、電線Ｗ０の前端への端子Ｃ１の圧着が完了して半完成状態の電線Ｗ１が得られ、端子Ｃ１が切断手段２に対向している状態では、この電線Ｗ１の前端部分は測長供給手段１の保持部１ａによって保持されている。
　このとき、図示されない制御手段によって電動モータ１７を反時計方向に回動させると、電線把持手段７０の把持爪７４は、図１１に示した第１の位置に到着する。
　この第１の位置においては、把持爪７４の向きは、案内部材６５と、この案内部材６５をその幅方向に挟持するローラ７３ｂ，７８ａとの係合により、前方に延びている電線Ｗ１を左右方向の挟持可能な向きに規定されている。 As shown in FIG. 1, the crimping of the terminal C1 to the front end of the electric wire W0 is completed to obtain a semi-finished electric wire W1, and when the terminal C1 faces the cutting means 2, the electric wire W1 The front end portion is held by the holding portion 1 a of the length measurement supply means 1.
At this time, when the electric motor 17 is rotated counterclockwise by a control means (not shown), the gripping claws 74 of the wire gripping means 70 arrive at the first position shown in FIG.
In this first position, the direction of the gripping claw 74 is such that the electric wire W1 extending forward is left and right by the engagement between the guide member 65 and the rollers 73b and 78a that sandwich the guide member 65 in the width direction. It is defined as the direction in which the direction can be clamped.
　次いで、電線把持手段７０のエアシリンダ７５を作動させて把持爪７４を降下させた後、エアシリンダ７６を作動させて把持爪７４を閉じると、把持爪７４によって電線Ｗ１の前端部分を把持することができる。
　その後、電動モータ１７を時計方向に回動させると、電線把持手段７０の把持爪７４は、図１１に示した第２の位置に到着する。
　この第２の位置においては、把持爪７４は、案内部材６５と、この案内部材６５をその幅方向に挟持するローラ７３ｂ，７８ａとの係合により、電線Ｗ１が後方に向かって延びるように電線Ｗ１の前端部分を把持するようにその向きが規定されている。
　より具体的に説明すると、第２の位置における把持爪７４の向きは、第１の位置における把持爪７４の向きに対し１８０度反転している。 Next, after operating the air cylinder 75 of the electric wire gripping means 70 to lower the gripping claws 74 and then operating the air cylinder 76 to close the gripping claws 74, the gripping claws 74 grip the front end portion of the electric wire W1. Can do.
Thereafter, when the electric motor 17 is rotated clockwise, the gripping claws 74 of the wire gripping means 70 arrive at the second position shown in FIG.
In this second position, the gripping claw 74 is such that the electric wire W1 extends rearward by the engagement between the guide member 65 and the rollers 73b and 78a holding the guide member 65 in the width direction. The direction is defined so as to grip the front end portion of W1.
More specifically, the orientation of the gripping claws 74 at the second position is inverted by 180 degrees with respect to the orientation of the gripping claws 74 at the first position.
　また、電線把持手段７０の把持爪７４が電線Ｗ１の前端部分を把持しつつＵ字形に延びる所定の軌道に沿って移動するのと同時に、測長供給手段１は、電線Ｗ１の基端部分を所定の長さだけ前方に送り出す。
　これにより、電線Ｗ１は、図１に示したようにＵ字形に湾曲して延びることになる。 At the same time as the gripping claw 74 of the wire gripping means 70 moves along a predetermined track extending in a U shape while gripping the front end portion of the wire W1, the length measuring and feeding means 1 moves the base end portion of the wire W1. Send it forward a predetermined length.
Thereby, the electric wire W1 is curved and extends in a U shape as shown in FIG.
　すなわち、本第２実施形態の電線反転機構２００は、電線端末処理装置１０の基台１１に固定されて上方に延びる支柱１２と、この支柱１２に支持されて電線端末処理装置１０の上方で水平に延びる基板１３と、この基板１３に支持されて所定の軌道に沿って移動する電線把持手段７０とを備える構造である。
　これにより、電線反転機構を備えていない既存の電線端末処理装置１０においても、支柱１２を立設するためのスペースを確保できれば、この既存の電線端末処理装置１０に本第１実施形態の電線反転機構１００を容易に後付けすることができる。 That is, the electric wire reversing mechanism 200 according to the second embodiment includes a support column 12 that is fixed to the base 11 of the electric wire terminal processing device 10 and extends upward, and is supported by the support column 12 and horizontally above the electric wire terminal processing device 10. And a wire gripping means 70 that is supported by the substrate 13 and moves along a predetermined track.
Thereby, even in the existing wire terminal processing device 10 that does not include the wire reversing mechanism, if the space for standing the support column 12 can be secured, the wire reversal of the first embodiment is added to the existing wire terminal processing device 10. The mechanism 100 can be easily retrofitted.
　また、本第２実施形態の電線反転機構２００は、基板１３の下方に支持した棒状の案内部材６５によって、Ｕ字形に延びる所定の軌道に沿って電線把持手段７０が移動するように案内する構造である。
　これにより、本第２実施形態の電線反転機構２００は、既存の電線端末処理装置１０に後付け可能な構造でありながら、電線把持手段７０、したがって電線Ｗ１の前端部分を正確に案内して電線Ｗ１をＵ字形に反転させることができる。 The electric wire reversing mechanism 200 according to the second embodiment is structured such that the electric wire gripping means 70 is moved along a predetermined track extending in a U shape by a bar-shaped guide member 65 supported below the substrate 13. It is.
As a result, the electric wire reversing mechanism 200 of the second embodiment is structured to be retrofitted to the existing electric wire terminal processing apparatus 10, but accurately guides the electric wire gripping means 70, and thus the front end portion of the electric wire W <b> 1. Can be inverted into a U-shape.
　また、本第２実施形態の電線反転機構２００は、基板１３に設けた電動モータ１７によって一対のプーリ６１，６２を回動させて無端状のベルト６３を周回させるとともに、このベルト６３に固定した周回体７１によって電線把持手段７０を駆動し、かつ電線把持手段７０を案内部材６５によって上下方向に支持しつつその移動を案内して、Ｕ字形に延びる所定の軌道上で電線把持手段７０を移動させる構造である。
　これにより、本第２実施形態の電線反転機構２００は、既存の電線端末処理装置に後付け可能なものでありながら、小型で、かつ電線をＵ字形に反転させる動作を高速に実行することができる。 Further, the electric wire reversing mechanism 200 of the second embodiment rotates the pair of pulleys 61 and 62 by the electric motor 17 provided on the substrate 13 to rotate the endless belt 63 and is fixed to the belt 63. The wire gripping means 70 is driven by the rotating body 71, and the movement is guided while the wire gripping means 70 is supported in the vertical direction by the guide member 65, and the wire gripping means 70 is moved on a predetermined track extending in a U-shape. It is a structure to let you.
As a result, the electric wire reversing mechanism 200 of the second embodiment can be retrofitted to an existing electric wire terminal processing apparatus, but is small in size and can execute an operation of reversing the electric wire into a U shape at high speed. .
　また、本第２実施形態の電線反転機構２００は、一対のプーリ６１，６２に巻回した無端状のベルト６３によって電線把持手段７０を駆動する構造である。
　これにより、Ｕ字形に延びる所定の軌道のうち、円弧状に湾曲する部分の半径を小さくせざるを得ない場合にも、容易に対応することができる。
　また、Ｕ字形に反転させる電線の前端部分を電線把持手段７０が把持するときの前後方向の位置は、一対のプーリ６１，６２に巻回されて長円状に延びる無端状ベルト６３のうち直線状に延びる部分の任意の位置に設定することができるから、既存の電線端末処理装置１０の構造に合わせて自在に調整することができる。 The electric wire reversing mechanism 200 according to the second embodiment has a structure in which the electric wire gripping means 70 is driven by an endless belt 63 wound around a pair of pulleys 61 and 62.
Thereby, it is possible to easily cope with the case where the radius of the arcuately curved portion of the predetermined trajectory extending in the U shape has to be reduced.
Further, the position in the front-rear direction when the wire gripping means 70 grips the front end portion of the electric wire to be reversed into a U shape is a straight line of the endless belt 63 wound around the pair of pulleys 61 and 62 and extending in an oval shape. Since it can be set at an arbitrary position of the portion extending in a shape, it can be freely adjusted according to the structure of the existing wire terminal processing apparatus 10.
　以上、本発明の電線端末処理装置の電線反転機構の各実施形態について詳しく説明したが、本発明は上述した実施形態によって限定されるものではなく、種々の変更が可能であることは言うまでもない。
　例えば、上述した第２実施形態の電線反転機構２００においては、電線把持手段７０のアーム７３と案内部材６５とを互いに係合させているが、周回体７１と案内部材６５とを互いに係合させる構造とすることもできる。 As mentioned above, although each embodiment of the electric wire reversing mechanism of the electric wire terminal processing apparatus of this invention was described in detail, it cannot be overemphasized that this invention is not limited by embodiment mentioned above and various changes are possible.
