Description

本発明は、被覆電線の芯線部を捩る電線捩り装置、それを備えた電線処理装置及び電線処理方法に関する。 The present invention relates to an electric wire twisting device for twisting a core wire portion of a covered electric wire, an electric wire processing device including the electric wire twisting device, and an electric wire processing method.

従来より、芯線部とこれを覆う被覆部で構成された被覆電線の被覆部を剥ぎ、その中心の芯線部を捩る作業を行って芯線部を整えた後、ハンダ付けを行うことが行われている。例えば、特許文献１の電線の端部を捩る捩り機は、切り込みが入れられて電線に沿って途中までスライドした被覆端部を把持するチャックと、このチャックを電線軸周りに回転させて電線を捩る機構と、被覆端部が収容されるパイプと、このパイプ内を吸引して被覆端部を回収する吸引機構とを備えている。 Conventionally, the coating portion of the coated electric wire composed of the core wire portion and the coating portion covering the core wire portion is peeled off, the core wire portion at the center thereof is twisted to prepare the core wire portion, and then soldering is performed. There is. For example, the twisting machine that twists the end of an electric wire of Patent Document 1 includes a chuck that grips a covered end that is notched and slides halfway along the electric wire, and a chuck that rotates this chuck around an electric wire axis to twist the electric wire. It is provided with a twisting mechanism, a pipe in which the covered end portion is housed, and a suction mechanism that sucks the inside of the pipe and collects the covered end portion.

しかしながら、従来の電線捩り装置では、被覆電線の被覆部に切り込みを入れてスライドさせた後、一旦被覆電線を後退させてから、電線径方向に移動させ電線の端部を捩る捩り機前方に搬送後、その先端を電線長手方向に前進させ、チャックの一対の爪部材の間の隙間の中心に正確に挿入しなければならない。特に被覆電線を掴んだ位置から端部までの距離が長い場合、端部先端の曲がりによる位置ずれが生じやすくなり、チャックで被覆電線を掴んだ状態でその先端を一対の爪部材間に正確に挿入しなければならない。このため、電線の先端の撓みも考慮して正確に先端を挿入しなければならず、正確な位置制御が必要となる。また、一対の爪部材間に電線を正しく挿入するために、その手前側に電線のガイド部材を配置したり、一対の爪部材の開口を大きく広げたりするようにすれば、より確実に電線を挿入できるが、ガイド部材を配置すれば、部品点数が増加して構造が複雑になり、爪部材の開口を広げるようにすれば、その開閉動作に余計な時間が必要になる。また、被覆電線の被覆部に切り込みを入れてスライドさせた後、一旦被覆電線を後退させてから横移動し、次の捩り工程処理時に電線先端側から電線長手方向に前進させ、爪部材間に挿入した場合、被覆電線を前後進させる分だけ、工程時間が長くなる。 However, in the conventional electric wire twisting device, after making a notch in the coated portion of the coated electric wire and sliding it, the coated electric wire is once retracted and then moved in the radial direction of the electric wire to be conveyed to the front of the twisting machine that twists the end portion of the electric wire. After that, its tip must be advanced in the longitudinal direction of the wire and inserted exactly into the center of the gap between the pair of claw members of the chuck. Especially when the distance from the position where the covered wire is gripped to the end is long, the position shift due to the bending of the tip of the end is likely to occur, and the tip is accurately held between the pair of claw members while the covered wire is gripped by the chuck. Must be inserted. Therefore, the tip must be inserted accurately in consideration of the bending of the tip of the electric wire, and accurate position control is required. Further, in order to correctly insert the electric wire between the pair of claw members, if the guide member of the electric wire is arranged in front of the pair of claw members or the opening of the pair of claw members is widened, the electric wire can be more reliably inserted. Although it can be inserted, if the guide member is arranged, the number of parts increases and the structure becomes complicated, and if the opening of the claw member is widened, an extra time is required for the opening / closing operation. In addition, after making a notch in the covered part of the covered wire and sliding it, the covered wire is once retracted and then moved laterally, and is advanced from the tip side of the wire in the longitudinal direction of the wire during the next twisting process, and is placed between the claw members. When inserted, the process time becomes longer by the amount that the covered wire is moved forward and backward.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、簡単な装置構成でありながら、安易且つ迅速な操作により、芯線部の捩り作業を正確に効率よく行うことにある。 The present invention has been made in view of the above points, and an object of the present invention is to accurately and efficiently twist the core wire portion by an easy and quick operation while having a simple device configuration. is there.

以下、本発明の実施形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図４に示されるように、本発明の実施形態に係る電線処理装置１は、フロントクランプ２ａを備えた測長ユニット２と、カッターユニット３と、クランプ部としてのリヤクランプ４と、捩りユニット５と、フラックスユニット６と、ハンダユニット７と、端子圧着ユニット８と、測長ユニット２やリヤクランプ４を移動させる移動手段９，１０とを有する。 As shown in FIG. 4, the electric wire processing device 1 according to the embodiment of the present invention includes a length measuring unit 2 provided with a front clamp 2a, a cutter unit 3, a rear clamp 4 as a clamp portion, and a twisting unit 5. The flux unit 6, the solder unit 7, the terminal crimping unit 8, and the moving means 9 and 10 for moving the length measuring unit 2 and the rear clamp 4 are provided.

そして、被覆電線１２の処理の流れについて簡単に説明すると、測長ユニット２により被覆電線１２が電線送給ラインＸに沿って矢印Ｐ方向に所定量送給され、クランプ部としてのフロントクランプ２ａにより被覆電線１２が把持される。 Then, briefly explaining the processing flow of the covered electric wire 12, the length measuring unit 2 feeds the coated electric wire 12 in a predetermined amount in the direction of the arrow P along the electric wire feeding line X, and the front clamp 2a as a clamp portion feeds the covered electric wire 12 in a predetermined amount. The covered electric wire 12 is gripped.

フロントクランプ２ａ側の被覆電線１２は、端部がカッターユニット３により切断された後、端部の芯線を露出させるために皮剥処理される。その後、端子圧着ユニット８の位置に移動されて、端子圧着ユニット８により被覆電線１２の先端部に端子が圧着され、その後、フロントクランプ２ａは初期位置に戻される。 The coated electric wire 12 on the front clamp 2a side is peeled to expose the core wire at the end after the end is cut by the cutter unit 3. After that, the terminal is moved to the position of the terminal crimping unit 8, the terminal is crimped to the tip of the coated electric wire 12 by the terminal crimping unit 8, and then the front clamp 2a is returned to the initial position.

その後、フロントクランプ２ａの把持が解除され、被覆電線が測長されながら送給され、所定長さ送られる。その後、フロントクランプ２ａとリヤクランプ４の両クランプで把持され、カッターユニット３により被覆電線１２が切断されると共に、切断された被覆電線１２の両端部の被覆部１２ｂが皮剥処理される。この際、リヤクランプ４側に把持されている切断された被覆電線１２の被覆部１２ｂは芯線部１２ａから脱落しない、いわゆるハーフストリップ状態とされる。なお、被覆部１２ｂを脱落させるストリップ状態としてもよい。 After that, the grip of the front clamp 2a is released, and the covered electric wire is fed while being measured in length, and is fed by a predetermined length. After that, it is gripped by both the front clamp 2a and the rear clamp 4, and the coated electric wire 12 is cut by the cutter unit 3, and the coated portions 12b at both ends of the cut coated electric wire 12 are peeled. At this time, the coated portion 12b of the cut coated electric wire 12 gripped on the rear clamp 4 side is in a so-called half-strip state in which the coated portion 12b does not fall off from the core wire portion 12a. It should be noted that the stripped state may be used in which the covering portion 12b is dropped off.

そして、リヤクランプ４側の被覆電線１２はその後、移動手段１０により捩りユニット５の位置に移動され、捩りユニット５により芯線部１２ａに捩り加工が施されると共に被覆部１２ｂが芯線部１２ａより抜き取られる。 Then, the covered electric wire 12 on the rear clamp 4 side is then moved to the position of the twisting unit 5 by the moving means 10, the core wire portion 12a is twisted by the twisting unit 5, and the covering portion 12b is pulled out from the core wire portion 12a. Is done.

その後、フラックスユニット６の位置に移動され、フラックスユニット６のフラックス槽６ａ内に芯線部１２ａが浸漬される。 After that, it is moved to the position of the flux unit 6 and the core wire portion 12a is immersed in the flux tank 6a of the flux unit 6.

次に、このフラックス液が付着した被覆電線１２をハンダユニット７位置に移動させ、ハンダユニット７のハンダ槽７ａ内に芯線部１２ａが浸漬されて芯線部１２ａにハンダが付着される。ハンダが付着された被覆電線１２は所定の電線排出部（図示せず）に排出される。その後、図４に示されるように、フロントクランプ２ａとリヤクランプ４とが対向する初期位置に戻される。 Next, the coated electric wire 12 to which the flux liquid is attached is moved to the position of the solder unit 7, the core wire portion 12a is immersed in the solder tank 7a of the solder unit 7, and the solder is adhered to the core wire portion 12a. The coated electric wire 12 to which the solder is attached is discharged to a predetermined electric wire discharging portion (not shown). After that, as shown in FIG. 4, the front clamp 2a and the rear clamp 4 are returned to the initial positions facing each other.

以上の動作の繰り返しにより、一端部に端子が圧着されると共に他端部にハンダが付着された被覆電線１２が順次製造されるようになっている。 By repeating the above operation, the coated electric wire 12 in which the terminal is crimped to one end and the solder is attached to the other end is sequentially manufactured.

The posture can be switched to a waste discharge posture having a vertical gap (not shown) formed by the two members 26b opening left and right and extending in the vertical direction. As shown in FIG. 2A, inclined surfaces 26d are formed on the insertion side of the covered electric wire 12 in the first member 26a and the second member 26b so that the distance becomes narrower toward the gripping position of the end portion. ing.

また、電線捩り装置１１は、チャック部２６が芯線部１２ａを捩った後に左右に第１部材２６ａと第２部材２６ｂとを開いた状態で空気を押し出して被覆部１２ｂの屑を下方へ吹き飛ばす被覆屑排出部２７を備えている。具体的には、被覆屑排出部２７は、チャック部２６の上方に接続されたエア配管２７ａと、このエア配管２７ａに接続されたノズル部２７ｂとを備え、制御部３６が図示しないコンプレッサに接続されたバルブを開閉することにより、ノズル部２７ｂから高圧エアが第１部材２６ａ及び第２部材２６ｂ側へ噴出されるようになっている。例えば、チャック部２６の下方に被覆部１２ｂの屑を集める容器などを設けていてもよい。 Further, the electric wire twisting device 11 pushes out air with the first member 26a and the second member 26b open to the left and right after the chuck portion 26 twists the core wire portion 12a, and blows the dust of the covering portion 12b downward. A coating waste discharging unit 27 is provided. Specifically, the coating waste discharging unit 27 includes an air pipe 27a connected above the chuck unit 26 and a nozzle unit 27b connected to the air pipe 27a, and the control unit 36 is connected to a compressor (not shown). By opening and closing the valve, high-pressure air is ejected from the nozzle portion 27b toward the first member 26a and the second member 26b. For example, a container for collecting the scraps of the covering portion 12b may be provided below the chuck portion 26.

−電線処理方法−
次に、本実施形態に係る電線処理方法の主要な部分について図５を用いて説明する。本実施形態では、制御部３６が操作パネル３７の入力に合わせて電線処理装置１の制御を行う。 -Electric wire processing method-
Next, the main part of the electric wire processing method according to the present embodiment will be described with reference to FIG. In the present embodiment, the control unit 36 controls the electric wire processing device 1 in accordance with the input of the operation panel 37.

まず、上述した上流側の各工程において、被覆電線１２のフロント側に端子が圧着された後、リヤ側の被覆部１２ｂに切り込みが入れられて被覆部１２ｂがわずかにずらされてハーフストリップ状態となる。 First, in each of the steps on the upstream side described above, after the terminals are crimped to the front side of the covered electric wire 12, a notch is made in the covering portion 12b on the rear side, and the covering portion 12b is slightly shifted to a half-strip state. Become.

次いで、把持工程において、ハーフストリップ状の被覆電線１２の端部近くをリヤクランプ４で掴む。 Next, in the gripping step, the rear clamp 4 grips the vicinity of the end of the half-strip-shaped covered electric wire 12.

次いで、捩りユニット５の第１部材２６ａと第２部材２６ｂとを上下に開いて水平方向に延びる水平隙間２６ｃを形成した捩り準備状態とする。 Next, the first member 26a and the second member 26b of the twisting unit 5 are opened up and down to form a horizontal gap 26c extending in the horizontal direction, and the twisting ready state is set.

次いで、挟み工程として、図５のステップＳ０１において、捩り要求を出す。そして、リヤクランプ４で掴んだ被覆電線１２のハーフストリップ部分を水平隙間２６ｃ内に電線長手方向と交差する方向から水平移動させ挿入する。 Next, as a pinching step, a twist request is issued in step S01 of FIG. Then, the half-strip portion of the covered electric wire 12 gripped by the rear clamp 4 is horizontally moved and inserted into the horizontal gap 26c from the direction intersecting the longitudinal direction of the electric wire.

次いで、ステップＳ０２において、第１部材２６ａと第２部材２６ｂとを閉じてハーフストリップ部分を掴む。このとき、図２Ａに示すように、第１部材２６ａと第２部材２６ｂにおける、被覆電線１２の進入側の形状を被覆電線１２の把持位置に向かって間隔が狭くなるように形成しているので、被覆電線１２を挿入するときに、一対の傾斜面２６ｄによって誘導され、よりスムーズに被覆電線１２を挿入できる。このため、被覆電線１２の掴みミスを、より減らすことができる。 Next, in step S02, the first member 26a and the second member 26b are closed to grip the half-strip portion. At this time, as shown in FIG. 2A, the shapes of the first member 26a and the second member 26b on the approach side of the coated electric wire 12 are formed so that the distance between them becomes narrower toward the gripping position of the coated electric wire 12. , When the covered electric wire 12 is inserted, it is guided by the pair of inclined surfaces 26d, and the coated electric wire 12 can be inserted more smoothly. Therefore, it is possible to further reduce the error in grasping the covered electric wire 12.

次いで、ステップＳ０３において、リヤクランプ４が張り調整をする。適度に被覆電線１２を引っ張っていないと、芯線部１２ａに捩りを加えられないからである。 Next, in step S03, the rear clamp 4 adjusts the tension. This is because the core wire portion 12a cannot be twisted unless the covered electric wire 12 is pulled appropriately.

次いで、ステップＳ０４の捩り工程において、被覆電線１２の端部を掴んだ第１部材２６ａ及び第２部材２６ｂを、回転軸２２を中心に回転させて被覆電線１２の端部を捩る。同時にリヤクランプ４の電線長手方向への後退タイマをセットする。 Next, in the twisting step of step S04, the first member 26a and the second member 26b that grip the end portion of the coated electric wire 12 are rotated around the rotation shaft 22 to twist the end portion of the coated electric wire 12. At the same time, set the reverse timer of the rear clamp 4 in the longitudinal direction of the electric wire.

次いで、ステップＳ０５において、タイマが完了すると、リヤクランプ４に後退通知を行う。 Next, in step S05, when the timer is completed, the rear clamp 4 is notified of backward movement.

次いで、ステップＳ０６において、回転軸２２の回転を完了し、リヤクランプ４の電線長手方向への移動を完了させ、第１部材２６ａと第２部材２６ｂとを開く。 Next, in step S06, the rotation of the rotating shaft 22 is completed, the movement of the rear clamp 4 in the longitudinal direction of the electric wire is completed, and the first member 26a and the second member 26b are opened.

次いで、ステップＳ０７において、ハーフストリップモードであるかどうかを判定する。ハーフストリップモードであれば、ステップＳ０８に進み、ハーフストリップモードでなければ、被覆屑排出工程は不要なので、ステップＳ１１に飛ぶ。 Then, in step S07, it is determined whether or not the mode is in the half-strip mode. If it is in the half-strip mode, the process proceeds to step S08, and if it is not in the half-strip mode, the coating waste discharging step is unnecessary, so the process proceeds to step S11.

ステップＳ０８では、被覆屑排出工程として、捩りユニット５が芯線部１２ａを捩った後に回転軸２２をカス排出位置、すなわち、第１部材２６ａと第２部材２６ｂとが左右に開いた状態で並んだ状態にする。 In step S08, as a coating waste discharging step, after the twisting unit 5 twists the core wire portion 12a, the rotating shaft 22 is arranged at the waste discharging position, that is, the first member 26a and the second member 26b are opened to the left and right. Put it in the state.

次いで、ステップＳ０９において、ガス排出用エアを作動させると同時にエアタイマをセットする。このようにノズル部２７ｂから高圧エアを押し出して被覆部１２ｂの屑を下方へ吹き飛ばす。下方に回収する容器等を置くことで、容易且つ迅速に被覆部１２ｂの屑を回収できる。なお、このとき、捩りユニット５が芯線部１２ａを捩った後に左右に第１部材２６ａと第２部材２６ｂとを開いた状態で被覆部１２ｂの屑を下方に吸い込む被覆屑吸引工程を含むようにしてもよい。この場合でも、容易且つ迅速に被覆部１２ｂの屑を回収できる。 Next, in step S09, the air timer is set at the same time as the gas discharge air is operated. In this way, the high-pressure air is pushed out from the nozzle portion 27b to blow the dust of the covering portion 12b downward. By placing a container or the like to be collected below, the waste of the covering portion 12b can be easily and quickly collected. At this time, after the twisting unit 5 twists the core wire portion 12a, the covering dust suction step of sucking the dust of the covering portion 12b downward with the first member 26a and the second member 26b open to the left and right is included. May be good. Even in this case, the debris of the covering portion 12b can be easily and quickly collected.

次いで、ステップＳ１０において、エアタイマが終了すると、エアの供給を停止し、回転軸２２を第１部材２６ａと第２部材２６ｂとが上下に並ぶ水平状態に戻す。 Next, in step S10, when the air timer ends, the supply of air is stopped, and the rotating shaft 22 is returned to the horizontal state in which the first member 26a and the second member 26b are lined up and down.

次いで、ステップＳ１１で回転軸２２をリセットして次の被覆電線１２に対して準備する。 Next, in step S11, the rotating shaft 22 is reset to prepare for the next covered electric wire 12.

次いで、ステップＳ１２で第１部材２６ａと第２部材２６ｂとを上下に開いて次の捩り作業の準備をしてステップＳ０１に戻る。 Next, in step S12, the first member 26a and the second member 26b are opened up and down to prepare for the next twisting work, and the process returns to step S01.

このように本実施形態では、被覆電線１２の端部をハーフストリップ状態とし、その端部を捩るために捩りユニット５の第１部材２６ａと第２部材２６ｂとの間に挿入する際に、被覆電線１２を大きく前後進させることなく、水平に且つ電線長手方向と交差する方向に移動させて上下に開いた第１部材２６ａと第２部材２６ｂとの間の水平隙間２６ｃに挿入するので、工程時間が短くて済む。しかも、従来のように端部の先端を正確に位置決めする必要がなく、先端が多少撓んでいてもそのまま水平に且つ電線長手方向と交差する方向に移動すればよいので、制御が極めて容易である。また、短い工程で精度よく捩られた被覆電線１２の端部にハンダを付着させることができる。 As described above, in the present embodiment, the end portion of the covered electric wire 12 is in a half-strip state, and when the end portion is inserted between the first member 26a and the second member 26b of the twisting unit 5 in order to twist the end portion, the covering is provided. The electric wire 12 is moved horizontally and in a direction intersecting the longitudinal direction of the electric wire without being greatly moved forward and backward, and is inserted into the horizontal gap 26c between the first member 26a and the second member 26b opened vertically. The time is short. Moreover, it is not necessary to accurately position the tip of the end as in the conventional case, and even if the tip is slightly bent, it can be moved horizontally and in the direction intersecting the longitudinal direction of the electric wire, so that control is extremely easy. .. In addition, solder can be attached to the end of the coated electric wire 12 that has been twisted with high accuracy in a short process.

したがって、本実施形態に係る電線捩り装置１１によると、芯線部１２ａの捩り作業を正確に且つ効率よく行うことができる。 Therefore, according to the electric wire twisting device 11 according to the present embodiment, the twisting operation of the core wire portion 12a can be performed accurately and efficiently.

すなわち、上記実施形態では、端子圧着を行った後、捩りを加えてハンダの付着を行っているが、逆に先にフロント側で捩りを加えてハンダの付着を行った後、リヤ側で端子圧着を行ってもよい。また、本発明は、フロント側、リヤ側の両側が共にハンダ付着を行う電線処理装置１に利用してもよい。 That is, in the above embodiment, the terminals are crimped and then twisted to adhere the solder, but conversely, the front side is twisted to adhere the solder and then the terminals are attached to the rear side. It may be crimped. Further, the present invention may be used for the electric wire processing device 1 in which both the front side and the rear side are soldered.

上記実施形態では、被覆屑排出部２７を設けて被覆部１２ｂを下方へ吹き飛ばしているが、チャック部２６が芯線部１２ａを捩った後に左右に第１部材２６ａと第２部材２６ｂとを開いた状態で被覆部１２ｂの屑を下方に吸い込む被覆屑吸引部を設けてもよい。この場合は、下方にエア配管を設け、被覆部１２ｂの屑を吸い込むようにすれば、確実に屑を回収できる。なお、この際に屑を真下に吸い込まなくてもよく、斜めや側方から吸い込んでもよい。 In the above embodiment, the coating waste discharging portion 27 is provided to blow the covering portion 12b downward, but the chuck portion 26 twists the core wire portion 12a and then opens the first member 26a and the second member 26b to the left and right. A covering debris suction portion may be provided to suck the debris of the covering portion 12b downward in this state. In this case, if an air pipe is provided below and the dust of the covering portion 12b is sucked in, the dust can be reliably collected. At this time, it is not necessary to suck the waste directly below, and it may be sucked diagonally or from the side.
