Description

本発明は、導電線絶縁被膜の剥離装置及びその剥離方法に関する。更に詳しくは、極細の導電線に好適な絶縁被膜の剥離装置及びその剥離方法に関するものである。   The present invention relates to a conductive wire insulating film peeling apparatus and a peeling method thereof. More particularly, the present invention relates to an insulating film peeling apparatus suitable for ultrafine conductive wires and a peeling method thereof.

従来、この種の絶縁被膜付導電線を端子やリード線に半田付け、ロウ付けする場合、その絶縁被膜をその都度剥してから半田付け、ロウ付け等がされる。この絶縁被膜の剥離作業を効率的に行うため、従来から、導電線の供給経路中に絶縁被膜の剥離装置を設け、供給中の導電線の絶縁被膜を必要なタイミングで剥離する方法が知られている。   Conventionally, when this type of conductive wire with an insulating coating is soldered and brazed to a terminal or a lead wire, the insulating coating is peeled off each time before soldering or brazing. In order to efficiently perform the stripping operation of the insulating coating, a method has been conventionally known in which an insulating coating stripping device is provided in the conductive wire supply path, and the insulating coating of the conductive wire being supplied is stripped at a necessary timing. ing.

そして、このような剥離装置として、駆動手段のモータにより回転される回転部材と、その回転部材にピンにより揺動自在に枢支された揺動アームと、その揺動アームの一端側に設けた錘と、他端に設けたカッタ及び摩擦部材と、その揺動アームをカッタが待機する方向へ付勢するコイルバネからなる付勢手段とを備えたものが知られている（例えば、特許文献１参照。）。このような剥離装置では、モータの回転により、回転部材を回転させて、錘に遠心力を発生させて、付勢手段の付勢力に抗して揺動アームを揺動させ、そのアームの他端に設けられたカッタを導電線の被膜に食い込ませることにより、その被膜を除去するようになっている。そして、導電線へのカッタの接触圧は、錘に作用する遠心力で決められるようになっている。   As such a peeling device, a rotating member rotated by the motor of the driving means, a swinging arm pivotally supported by the rotating member by a pin, and one end of the swinging arm are provided. A device including a weight, a cutter and a friction member provided at the other end, and a biasing means including a coil spring that biases the swing arm in a direction in which the cutter waits is known (for example, Patent Document 1). reference.). In such a peeling device, the rotating member is rotated by the rotation of the motor to generate centrifugal force on the weight, and the swinging arm is swung against the biasing force of the biasing means. The coating provided on the end is removed by encroaching the coating on the conductive wire. The contact pressure of the cutter to the conductive wire is determined by the centrifugal force acting on the weight.

しかし、揺動アームを有する上記従来の剥離装置では、導電線が太い場合には回転部材の回転速度を高くしてある程度大きい接触圧を与えても導電線に断線などがなく効率的に絶縁被膜を剥離できるものの、揺動アームの支点とカッタまでの距離が比較的長く、カッタの移動量が比較的大きいことから導電線へのカッタの接触圧が回転部材の回転速度に正確に比例せずにばらつくと言う不具合があった。このため、導電線が細い場合には回転部材の回転速度を低くして小さい接触圧を与えようとしても、そのばらつきによりその接触圧が高まり、その導電線が断線する不具合があった。一方、このばらつきを考慮して、導電線が細い場合の回転部材の回転速度をより低くすると、その接触圧が著しく低下して絶縁被膜の剥離を完全に行うことができない場合もあった。また、この導電線への接触圧を調整するため、錘の重量や錘の取付け位置を変更することも考えられるが、試行錯誤の煩雑な作業を伴い、微妙な剥離量の管理を行うことが難しいものであった。   However, in the above conventional peeling apparatus having a swing arm, when the conductive wire is thick, even if the rotational speed of the rotating member is increased to give a certain level of contact pressure, the conductive wire is not disconnected and is efficiently insulated. Although the distance between the fulcrum of the oscillating arm and the cutter is relatively long and the amount of movement of the cutter is relatively large, the contact pressure of the cutter to the conductive wire is not exactly proportional to the rotational speed of the rotating member. There was a problem that it was scattered. For this reason, when the conductive wire is thin, even if an attempt is made to reduce the rotation speed of the rotating member to give a small contact pressure, the contact pressure is increased due to the variation, and the conductive wire is disconnected. On the other hand, in consideration of this variation, if the rotation speed of the rotating member when the conductive wire is thin is made lower, the contact pressure is remarkably lowered, and the insulating coating may not be completely peeled off. In order to adjust the contact pressure to the conductive wire, it is conceivable to change the weight of the weight and the mounting position of the weight. However, it is difficult to manage the delicate amount of separation with complicated work of trial and error. It was difficult.

このような不具合を解消すべく、本出願人は、回転部材の中心軸回りに等間隔に複数のカッタシャフトをそれらの軸心を中心にそれぞれが回動可能に配置した剥離装置を提案した（例えば、特許文献２参照。）。この剥離装置では、そのカッタシャフトの前端にカッタシャフトの回転により回転部材の前端から前方に突出した導電線に接離可能なカッタを設け、そのカッタシャフトの後端に回転部材の回転に伴う遠心力によりカッタを導電線側に押圧するようにカッタシャフトを回動させる錘を設けている。   In order to solve such a problem, the present applicant has proposed a peeling device in which a plurality of cutter shafts are arranged at equal intervals around the central axis of the rotating member so that each of them can be rotated around their axial centers ( For example, see Patent Document 2.) In this peeling apparatus, a cutter is provided at the front end of the cutter shaft that can be brought into contact with and separated from the conductive wire protruding forward from the front end of the rotating member by the rotation of the cutter shaft, and the centrifugal shaft accompanying the rotation of the rotating member is provided at the rear end of the cutter shaft. A weight for rotating the cutter shaft so as to press the cutter toward the conductive wire by force is provided.

この導電線絶縁被膜の剥離装置では、回転部材の回転速度に応じて、遠心力により錘がカッタシャフトを回転させ、カッタの刃部を導電線の軸心側に移動させてその刃部を導電線の被膜に食い込ませることにより、その被膜を除去するようになっている。このようにシャフトと共にカッタ自体を回動させることにより、揺動アームを用いる場合に比較してカッタの移動量を小さくすることができ、導電線へのカッタの接触圧を比較的安定させることができるので、導電線が細い場合であってもその導電線を断線させることなく絶縁被膜を剥離することができるようになっている。   In this conductive wire insulation film peeling device, the weight rotates the cutter shaft by centrifugal force according to the rotation speed of the rotating member, and the blade portion of the cutter is moved to the axial center side of the conductive wire to conduct the blade portion. The film is removed by biting into the film of the wire. By rotating the cutter itself together with the shaft in this way, the amount of movement of the cutter can be reduced compared with the case of using a swing arm, and the contact pressure of the cutter to the conductive wire can be made relatively stable. Therefore, even when the conductive wire is thin, the insulating coating can be peeled off without breaking the conductive wire.

そして、図６に示すように、このカッタシャフト２を備えた導電線絶縁被膜の剥離装置では、遠心力Ｆに対抗してカッタを導電線から離反する方向にカッタシャフト２を回動付勢するコイルバネ３を更に設けている。このコイルバネ３は錘４にシャフト２と偏倚して設けられたピン５と回転部材６に固定された取付リング７との間に架設され、そのピン５を介して遠心力Ｆによりシャフト２を中心として回転しようとする方向と逆方向に錘４を引張り、カッタを導電線から離反する方向にカッタシャフト２を回動付勢するようになっている。このため、このコイルバネ３はその引張り力Ｇにより錘４に加わる遠心力Ｆを受止め、両者が釣合う状態までカッタシャフト２を回動させる。従って、回転部材６の一点鎖線矢印で示すような方向の回転速度を高めるとカッタシャフト２の回動量が増加し、その前端に設けられたカッタがより導電線の軸線に近い位置まで移動することになる。よって、回転部材６の回転速度を調整することでカッタの回転中の位置を調整することができ、導電線の線径に対応して回転部材６の回転速度を変更調整することで、剥離作動中の導電線にカッタが過度に押圧されることを防止することができ、断線や導電部の削り取り等を防止するとともに、導電線が細い場合にも断線することなく絶縁被膜の剥離を行うことができると期待された。   Then, as shown in FIG. 6, in the conductive wire insulating film peeling device provided with the cutter shaft 2, the cutter shaft 2 is urged to rotate in a direction that opposes the centrifugal force F and separates the cutter from the conductive wire. A coil spring 3 is further provided. The coil spring 3 is installed between a pin 5 provided on the weight 4 so as to be offset from the shaft 2 and a mounting ring 7 fixed to the rotating member 6, and the shaft 2 is centered by the centrifugal force F via the pin 5. As a result, the weight 4 is pulled in the direction opposite to the direction of rotation, and the cutter shaft 2 is urged to rotate in a direction away from the conductive wire. For this reason, the coil spring 3 receives the centrifugal force F applied to the weight 4 by the tensile force G, and rotates the cutter shaft 2 until the two are balanced. Therefore, when the rotational speed in the direction as indicated by the one-dot chain line arrow of the rotating member 6 is increased, the amount of rotation of the cutter shaft 2 increases, and the cutter provided at the front end moves to a position closer to the axis of the conductive wire. become. Therefore, the position during rotation of the cutter can be adjusted by adjusting the rotation speed of the rotating member 6, and the peeling operation is performed by changing and adjusting the rotation speed of the rotating member 6 in accordance with the wire diameter of the conductive wire. It is possible to prevent the cutter from being pressed excessively by the conductive wire inside, prevent disconnection and scraping of the conductive part, etc., and peel off the insulating film without disconnection even when the conductive wire is thin Expected to be able to.

しかし、カッタシャフト２を用いた上記剥離装置では、カッタを導電線から離反する方向にカッタシャフト２を回動付勢するバネとしてコイルバネ３を用いているけれども、図５に示すように、回転部材６を回転させると、このコイルバネ３自体が遠心力により半径方向外側に撓んでしまうと言う不具合があった。そして、このコイルバネ３自体が撓むとピン５を介して錘４を付勢する付勢力Ｇが変動し、回転部材６の回転速度とカッタシャフト２の回動量を比例させることが困難となり、結果としてカッタの移動量を正確に制御することが困難になるという不具合が生じた。   However, in the peeling apparatus using the cutter shaft 2, the coil spring 3 is used as a spring that urges the cutter shaft 2 in a direction away from the conductive wire. However, as shown in FIG. When the motor 6 is rotated, the coil spring 3 itself is bent radially outward due to centrifugal force. And if this coil spring 3 itself bends, the urging force G which urges the weight 4 via the pin 5 will fluctuate, making it difficult to make the rotational speed of the rotating member 6 and the amount of rotation of the cutter shaft 2 proportional. There was a problem that it was difficult to accurately control the amount of movement of the cutter.

また、複数のカッタシャフト２を用いた上記剥離装置では、回転部材６に円板８を回転自在に設け、その周囲の切欠き８ａにピン５を係合させることにより各錘４のカッタシャフト２を中心とした回転を連係させているけれども、コイルバネ３がこの円板８の外周を超えてその外側に膨らむように撓んでしまうと、回転部材６を回転可能に支持する図示しない支持台やこの剥離装置をケースに収容しているような場合にはその図示しないケースに高速で回転するコイルバネ３が接触し、カッタシャフト２の回動量が変化するとともにこのコイルバネ３及びピン５等が破損する不具合があった。また、コイルバネ３が他の部材と接触しない場合であっても、このコイルバネ３自体が撓みと復元を繰り返すことによる疲労によりコイルバネ３の取付部位が破壊するという不具合もあった。   Further, in the peeling device using a plurality of cutter shafts 2, the disk 8 is rotatably provided on the rotating member 6, and the pins 5 are engaged with the peripheral notches 8 a to engage the cutter shaft 2 of each weight 4. However, if the coil spring 3 is bent so as to bulge outward beyond the outer periphery of the disk 8, a support base (not shown) that rotatably supports the rotating member 6 or this When the peeling device is accommodated in the case, the coil spring 3 rotating at high speed contacts the case (not shown), and the amount of rotation of the cutter shaft 2 changes and the coil spring 3 and the pin 5 are damaged. was there. Further, even when the coil spring 3 is not in contact with other members, there is a problem in that the attachment portion of the coil spring 3 is destroyed due to fatigue caused by repeated bending and restoration of the coil spring 3 itself.

本発明の目的は、回転部材の回転速度とカッタの移動量を正確に比例させて、回転部材の回転速度を調整することでカッタの回転中の位置を正確に調整し得る導電線絶縁被膜の剥離装置及びその剥離方法を提供することにある。   An object of the present invention is to provide a conductive wire insulating film capable of accurately adjusting the position of the cutter during rotation by adjusting the rotation speed of the rotation member by precisely proportionally rotating the rotation speed of the rotation member and the moving amount of the cutter. It is providing the peeling apparatus and its peeling method.

本発明の導電線絶縁被膜の剥離装置は、前後方向に延びる中心軸に貫通した導電線を中心に回転可能に設けられた回転部材と、その回転部材に中心軸に沿ってその中心軸回りに等間隔に配置され軸心を中心に回動可能に設けられた複数のカッタシャフトと、複数のカッタシャフトの前端にそれぞれ設けられカッタシャフトの回動により回転部材の前端から前方に突出した導電線に接離可能なカッタと、複数のカッタシャフトの後端に偏心してそれぞれ設けられ回転部材の回転に伴う遠心力によりカッタを導電線に押圧させるようにカッタシャフトを回動させる錘と、遠心力に対抗してカッタを導電線から離反させる方向にカッタシャフトを回動付勢するバネとを備えた導電線絶縁被膜の剥離装置の改良である。   A stripping device for a conductive wire insulation film according to the present invention includes a rotating member rotatably provided around a conductive line passing through a central axis extending in the front-rear direction, and the rotating member around the central axis along the central axis. A plurality of cutter shafts arranged at equal intervals so as to be rotatable around an axis, and a conductive wire provided at the front end of each of the plurality of cutter shafts and protruding forward from the front end of the rotating member by the rotation of the cutter shaft A cutter that can be contacted and separated from each other, a weight that is provided eccentrically at the rear ends of the plurality of cutter shafts, and that rotates the cutter shaft so as to press the cutter against the conductive wire by the centrifugal force accompanying the rotation of the rotating member, and centrifugal force And a spring for urging the cutter shaft in a direction to move the cutter away from the conductive wire against the above.

その特徴ある構成は、錘にカッタシャフトと偏倚してピンが設けられ、バネは、回転部材に基端が取付けられ湾曲して先端又は中間がピンに当接し弾性力により錘を遠心作用で回動する方向とは反対の方向に付勢する板バネであるところにある。   The characteristic configuration is that the weight is provided with a pin that is biased with the cutter shaft, and the spring is bent at the base end of the rotating member and the tip or middle abuts against the pin, and the weight is rotated by the centrifugal force by the elastic force. The leaf spring is biased in the direction opposite to the moving direction.

本発明の導電線絶縁被膜の剥離方法は、中心軸に沿って中心軸回りに等間隔にカッタシャフトが配置された回転部材を中心軸に貫通させた導電線Ａを中心に回転させ、カッタシャフトの後端に偏心して設けられた錘に回転部材の回転に伴う遠心力を作用させてカッタシャフトを回動させ、カッタシャフトの回動によりカッタシャフトの前端に設けられたカッタを回転部材の前端から前方に突出した導電線に押圧して導電線における被膜を除去する方法の改良である。   The method for peeling a conductive wire insulation coating according to the present invention comprises rotating a rotating member having a cutter shaft arranged at equal intervals around a central axis along a central axis, and rotating the conductive line A around the central axis to thereby rotate the cutter shaft. The cutter shaft is rotated by applying centrifugal force accompanying rotation of the rotating member to the weight eccentrically provided at the rear end of the cutter, and the cutter provided at the front end of the cutter shaft is rotated by the rotation of the cutter shaft. This is an improvement of the method of removing the coating on the conductive wire by pressing it against the conductive wire protruding forward.

その特徴ある点は、錘にカッタシャフトと偏倚してピンを設け、回転部材に基端が取付けられた板バネを湾曲させてその先端又は中間をピンに当接させ、板バネの弾性力により錘を遠心作用で回動する方向とは反対の方向に付勢してカッタシャフトの回動量を回転部材の回転速度により制御するところにある。   The characteristic point is that the weight is offset from the cutter shaft, a pin is provided, a leaf spring having a base end attached to the rotating member is bent, and the tip or middle is brought into contact with the pin, and the elastic force of the leaf spring is used. The weight is biased in the direction opposite to the direction of rotation by centrifugal action, and the amount of rotation of the cutter shaft is controlled by the rotation speed of the rotating member.

本発明の導電線絶縁被膜の剥離装置及びその剥離方法では、カッタを導電線から離反する方向にカッタシャフトを回動付勢するバネとして、遠心力により撓むようなことのない板バネを用いた。このため、遠心力が作用してもその板バネによる付勢力に変動が生じない。よって、回転部材の回転速度とカッタシャフトの回動量を比較的正確に比例させることができ、回転部材の回転速度を調整することにより、カッタシャフトに設けられたカッタの位置を比較的正確に制御することが可能となる。この結果、導電線の線径に対応してカッタシャフトの回動量を制御することで、剥離作動中の導電線にカッタが過度に押圧されることによる導電線の断線や導電部の削り取り等を防止できると共に、柔らかい表面の樹脂層からなる絶縁被膜を確実に剥離することが可能となる。即ち、導電線が細い場合にも断線することなく絶縁被膜を剥離することができることになる。   In the conductive wire insulating film peeling device and the peeling method of the present invention, a leaf spring that does not bend due to centrifugal force is used as a spring that urges the cutter shaft to rotate away from the conductive wire. . For this reason, even if a centrifugal force acts, the urging force by the leaf spring does not vary. Therefore, the rotational speed of the rotating member and the rotation amount of the cutter shaft can be proportionally proportional, and the position of the cutter provided on the cutter shaft can be controlled relatively accurately by adjusting the rotational speed of the rotating member. It becomes possible to do. As a result, by controlling the amount of rotation of the cutter shaft in accordance with the wire diameter of the conductive wire, disconnection of the conductive wire, scraping of the conductive portion, etc. due to excessive pressing of the cutter against the conductive wire during the peeling operation. In addition to being able to prevent this, it is possible to reliably peel off the insulating coating made of a soft resin layer. That is, even when the conductive wire is thin, the insulating film can be peeled without disconnection.

次に本発明を実施するための形態を図面に基づいて説明する。
図１に示すように、本発明の剥離装置１０は、中心軸に貫通した導電線Ａ(一点鎖線で示す。)を中心に回転可能に設けられた回転部材１１を備える。即ち、この回転部材１１は中空をなし、中空部内の前端にノズル１１ａを有し、そのノズル１１ａ後方の中空部内にはそこに挿通されて貫通する導電線Ａを保護するための樹脂チューブ１１ｅが挿入される。そして、樹脂チューブ１１ｅには後端から導電線Ａが挿入され、ノズル１１ａはその導電線Ａを振れないように位置決めして回転部材１１の前端から前方に繰出すように案内している。また、回転部材１１は、その外側の中央部分に外径の大きいフランジ１１ｂと、そのフランジ１１ｂより前方のノズル１１ａ側に小径のフランジ１１ｃとを所定の間隔を開けて互に平行となるように一体的に備えている。 Next, an embodiment for carrying out the present invention will be described with reference to the drawings.
As shown in FIG. 1, the peeling apparatus 10 of the present invention includes a rotating member 11 that is provided so as to be rotatable around a conductive wire A (shown by a one-dot chain line) penetrating the central axis. That is, the rotating member 11 is hollow, and has a nozzle 11a at the front end in the hollow portion. In the hollow portion behind the nozzle 11a, there is a resin tube 11e inserted there to protect the conductive wire A passing therethrough. Inserted. Then, the conductive wire A is inserted into the resin tube 11e from the rear end, and the nozzle 11a is positioned so that the conductive wire A cannot be shaken and guided so as to be fed forward from the front end of the rotating member 11. Further, the rotating member 11 has a flange 11b having a large outer diameter at the center portion on the outer side thereof and a flange 11c having a small diameter on the nozzle 11a side in front of the flange 11b so as to be parallel to each other with a predetermined interval. Integrated.

回転部材１１に一体的に形成された両フランジ１１ｂ，１１ｃには、これら両フランジ１１ｂ，１１ｃを跨って複数のカッタシャフト１２がその軸心を中心に回動可能に貫通して設けられる。複数のカッタシャフト１２は回転部材１１に沿い、この回転部材１１の中心軸回りに等間隔に配置される。図３及び図４に示すように、この実施の形態におけるカッタシャフト１２は、回転部材１１を中心として１２０°間隔で３本配置され、かつ回転部材１１に対し前方のフランジ１１ｃよりも後方のフランジ１１ｂ側で取付け半径が大きくなるように傾斜して設けられる。なお、図示しないが、カッタシャフト１２のフランジ１１ｂ、１１ｃへの貫通部にはベアリングやブッシュが設けられ、カッタシャフト１２の回動抵抗を減じるように構成される。   A plurality of cutter shafts 12 are provided through both flanges 11b and 11c formed integrally with the rotating member 11 so as to be able to rotate about the axis centering over both the flanges 11b and 11c. The plurality of cutter shafts 12 are arranged along the rotary member 11 at regular intervals around the central axis of the rotary member 11. As shown in FIGS. 3 and 4, three cutter shafts 12 in this embodiment are arranged at intervals of 120 ° with the rotating member 11 as the center, and the rear flange with respect to the rotating member 11 than the front flange 11 c. 11b is provided so as to be inclined so that the mounting radius becomes large. Although not shown, a bearing or a bush is provided in a portion where the cutter shaft 12 penetrates to the flanges 11b and 11c so that the rotational resistance of the cutter shaft 12 is reduced.

図１及び図３に示すように、これら複数のカッタシャフト１２の前端にはカッタ１３が導電線Ａ（図１）を取囲むように固定される。具体的には、回転部材１１の前端から前方に突出した複数のカッタシャフト１２の前端にカッタ１３が取付けられ、このカッタ１３は、カッタシャフト１２の回動により回転部材１１の前端から前方に突出した導電線Ａに接離可能に構成される。即ち、カッタシャフト１２はノズル１１ａ側で回転部材１１に近づくよう傾けて取付けられており、カッタシャフト１２の前端に止められたカッタ１３は折曲げられて導電線Ａの側方に延び、その側面に刃先１３ａが形成されていて導電線Ａには斜めに接触するようになっている。これにより回転部材１１の中心軸を後端から前方に向かって移動している導電線Ａにカッタ１３の刃部１３ａが回転しながらヘリカル状に接触してゆくとき、刃部１３ａがこのヘリカル線と交差することになり、幅広く絶縁被膜を剥離できるようになっている。   As shown in FIGS. 1 and 3, a cutter 13 is fixed to the front ends of the plurality of cutter shafts 12 so as to surround the conductive wire A (FIG. 1). Specifically, a cutter 13 is attached to the front ends of a plurality of cutter shafts 12 protruding forward from the front end of the rotating member 11, and the cutter 13 protrudes forward from the front end of the rotating member 11 by the rotation of the cutter shaft 12. The conductive wire A is configured so as to be capable of contacting and separating. That is, the cutter shaft 12 is attached to be inclined so as to approach the rotating member 11 on the nozzle 11a side, and the cutter 13 stopped at the front end of the cutter shaft 12 is bent and extends to the side of the conductive wire A, and its side surface. A blade edge 13a is formed on the conductive wire A so as to contact with the conductive wire A at an angle. As a result, when the blade portion 13a of the cutter 13 comes into helical contact with the conductive wire A moving on the central axis of the rotating member 11 from the rear end toward the front, the blade portion 13a is in contact with this helical wire. The insulation film can be peeled widely.

図１〜図３に示すように、各カッタシャフト１２の後端には錘１４がその重心がカッタシャフト１２の軸心と円周方向に偏心した状態で固定される。このため、回転部材１１とともにフランジ１１ｂ，１１ｃが導電線Ａを中心として回転すると、そのフランジ１１ｂ，１１ｃとともに複数のカッタシャフト１２は導電線Ａを中心として公転することになる。すると、図３の破線矢印で示すようにカッタシャフト１２の後端に設けられた錘１４に遠心力Ｆが作用し、その錘１４が半径方向外側に移動してカッタシャフト１２を回動させ、実線矢印で示すようにカッタ１３の刃部１３ａを導電線Ａに接近させることになる。ここで、導電線Ａを取囲むカッタ１３の複数の刃部１３ａは多角形（この場合は図３に示す３角形）を形成するので、本発明の剥離装置１０では錘１４に加わる遠心力Ｆが大きくなるときその多角形の大きさを小さくするように作動し、各カッタシャフト１２の回動（自転）位置に応じてカッタ１３の刃部１３ａが導電線Ａに接離する程度を変更可能に構成される。   As shown in FIGS. 1 to 3, a weight 14 is fixed to the rear end of each cutter shaft 12 in a state where the center of gravity is eccentric from the axis of the cutter shaft 12 in the circumferential direction. For this reason, when the flanges 11b and 11c rotate around the conductive wire A together with the rotating member 11, the plurality of cutter shafts 12 revolve around the conductive wire A together with the flanges 11b and 11c. Then, the centrifugal force F acts on the weight 14 provided at the rear end of the cutter shaft 12 as indicated by the broken line arrow in FIG. 3, and the weight 14 moves radially outward to rotate the cutter shaft 12, The blade portion 13a of the cutter 13 is brought close to the conductive wire A as indicated by the solid line arrow. Here, since the plurality of blade portions 13a of the cutter 13 surrounding the conductive wire A form a polygon (in this case, a triangle shown in FIG. 3), the centrifugal force F applied to the weight 14 in the peeling device 10 of the present invention. When the size of the cutter increases, the polygonal size is reduced so that the degree of contact of the blade 13a of the cutter 13 with the conductive wire A can be changed according to the rotation (spinning) position of each cutter shaft 12. Configured.

この錘１４にはカッタシャフト１２と平行にピン１６が貫通して設けられる。このピン１６は、カッタ１３が導電線Ａから離間した状態で、カッタシャフト１２より回転部材１１の半径方向外側の錘１４に設けられる。そしてこのピン１６の前端は大径フランジ１１ｂに設けた円周方向に延びる第１Ｕ字状溝１１ｄ（図３）に挿入されて錘１４の回動範囲、即ちカッタ１３の導電線Ａへの接離範囲を規制するように構成される。図１及び図３では、その第１Ｕ字状溝１１ｄに対応する第２Ｕ字状溝１７ａが周囲に形成されたストッパリング１７が大径フランジ１１ｂに重合して設けられ、このストッパリング１７は、このストッパリング１７に円周方向に形成された円弧状長孔１７ｂを介してビス１７ｃにより大径フランジ１１ｂの前面に取付けられている。そして、円弧状長孔１７ｂの範囲内でストッパリング１７の固定位置を円周方向に移動して調整し、第１及び第２Ｕ字状溝１１ｄ，１７ａの重複範囲においてピン１６の移動限を決め、これによりカッタ１３の最大開度を調整できるようになっている。なお、図３では錘１４のピン１６が円周方向に延びる第１及び第２Ｕ字状溝１１ｄ，１７ａに挿入されて、カッタ１３の導電線Ａへの接離範囲を規制する構造について説明したが、図示しないが、このピン１６をフランジ１１ｂに形成された長孔に挿入してそのピンの移動範囲を制限して、カッタ１３の導電線Ａへの接離範囲を規制するようにしても良い。   The weight 14 is provided with a pin 16 penetrating in parallel with the cutter shaft 12. The pin 16 is provided on the weight 14 on the radially outer side of the rotating member 11 with respect to the cutter shaft 12 in a state where the cutter 13 is separated from the conductive wire A. The front end of the pin 16 is inserted into a first U-shaped groove 11d (FIG. 3) extending in the circumferential direction provided on the large-diameter flange 11b, and the rotation range of the weight 14, that is, the contact of the cutter 13 with the conductive wire A is performed. It is configured to regulate the separation range. 1 and 3, a stopper ring 17 having a second U-shaped groove 17a corresponding to the first U-shaped groove 11d is formed around the large-diameter flange 11b. The stopper ring 17 is The stopper ring 17 is attached to the front surface of the large-diameter flange 11b by a screw 17c through an arc-shaped long hole 17b formed in the circumferential direction. Then, the fixing position of the stopper ring 17 is moved and adjusted in the circumferential direction within the range of the arc-shaped elongated hole 17b, and the movement limit of the pin 16 is determined in the overlapping range of the first and second U-shaped grooves 11d and 17a. Thus, the maximum opening of the cutter 13 can be adjusted. In FIG. 3, the structure in which the pin 16 of the weight 14 is inserted into the first and second U-shaped grooves 11d and 17a extending in the circumferential direction to regulate the contact / separation range of the cutter 13 with respect to the conductive wire A has been described. Although not shown, the pin 16 is inserted into a long hole formed in the flange 11b to restrict the range of movement of the pin so as to restrict the contact / separation range of the cutter 13 with respect to the conductive wire A. good.

図１及び図２に示すように、大径フランジ１１ｂの後方には、外周に複数個の放射方向に延びる切欠き１８ａを有する円板１８が、その大径フランジ１１ｂと共に錘１４を挟むように回転部材１１に回転自在に嵌合して設けられる。この円板１８は各錘１４を連係させるものであって、この円板１８における外周の切欠き１８ａには、錘１４に設けられたピン１６の他端がそれぞれ係合するように構成される。この円板１８の夫々の切欠き１８ａは、その次の隣の切欠き１８ａに向かって伸びる斜め方向に夫々形成され、錘１４に作用する遠心力Ｆにより移動するピン１６と切欠き１８ａの一方の縁とは若干転がり作用を生じながら接触している。このような円板１８により各錘１４の互いの回動位置は連係させられ、カッタ１３の刃部１３ａが均等に導電線Ａに接近しまた離脱するように構成され、これにより一部のカッタ１３のみが導電線Ａにより接近することを防止するようになっている。また、質量の差異等で錘１４相互の作動タイミングにずれがあったとしても、円板１８で互に連係されるため、錘１４の質量や偏心量の調整に厳密さを要求されないようにしている。なお、図１における符号１８ｂは、この円板１８の回転部材１１に対する回転抵抗を減少させるためのベアリング１８ｂである。   As shown in FIGS. 1 and 2, a disk 18 having a plurality of radially extending cutouts 18a on the outer periphery of the large-diameter flange 11b sandwiches the weight 14 together with the large-diameter flange 11b. The rotary member 11 is provided to be rotatably fitted. The disk 18 links the weights 14, and is configured such that the other end of the pin 16 provided on the weight 14 is engaged with a notch 18 a on the outer periphery of the disk 18. . Each notch 18a of the disc 18 is formed in an oblique direction extending toward the next adjacent notch 18a, and one of the pin 16 and the notch 18a moving by the centrifugal force F acting on the weight 14 is formed. It is in contact with the edge of this while causing a slight rolling action. The rotary positions of the respective weights 14 are linked by such a disc 18 so that the blade portion 13a of the cutter 13 approaches and detaches from the conductive wire A evenly. Only 13 is prevented from approaching the conductive wire A. Further, even if there is a deviation in the operation timing between the weights 14 due to a difference in mass or the like, the disks 18 are linked to each other, so that strictness is not required for adjusting the mass and eccentricity of the weight 14. Yes. In addition, the code | symbol 18b in FIG. 1 is the bearing 18b for reducing the rotational resistance with respect to the rotating member 11 of this disc 18. As shown in FIG.

図１及び図２に示すように、本発明の剥離装置１０には、錘１４に作用する遠心力Ｆに対抗してカッタ１３を導電線Ａから離反する方向にカッタシャフト１２を回動付勢するバネ２１を備える。本発明の特徴ある構成は、このバネが板バネ２１からなるところにある。即ち、大径フランジ１１ｂより後方の回転部材１１には取付リング１９が取付ねじ１９ａにより取付けられ、この取付リング１９に板バネ２１の基端が固定ねじ２１ａにより取付けられる。このように取付リング１９を介して回転部材１１に基端が取付けられた板バネ２１は、それ自体が湾曲してその先端又は中間がピン１６に当接するように構成される。先端又は中間がピン１６に当接した板バネ２１を湾曲させるためには、取付リング１９の回転部材１１への円周方向における取付位置を取付ねじ１９ａを緩めて調整することにより行われ、湾曲してその先端又は中間がピン１６に当接した板バネ２１はその弾性力により錘１４を、遠心作用でカッタシャフト１２が回動する方向とは反対の方向にピン１６を介して付勢するように構成される。   As shown in FIGS. 1 and 2, the peeling device 10 according to the present invention urges the cutter shaft 12 to rotate in a direction in which the cutter 13 is separated from the conductive wire A against the centrifugal force F acting on the weight 14. Spring 21 is provided. The characteristic configuration of the present invention is that this spring is composed of a leaf spring 21. That is, the attachment ring 19 is attached to the rotating member 11 behind the large-diameter flange 11b by the attachment screw 19a, and the base end of the leaf spring 21 is attached to the attachment ring 19 by the fixing screw 21a. The leaf spring 21 whose base end is attached to the rotating member 11 through the attachment ring 19 in this way is configured such that it is curved and a distal end or an intermediate portion abuts against the pin 16. In order to curve the leaf spring 21 whose tip or middle is in contact with the pin 16, the mounting position of the mounting ring 19 on the rotating member 11 in the circumferential direction is adjusted by loosening the mounting screw 19a. Then, the leaf spring 21 whose tip or middle is in contact with the pin 16 urges the weight 14 through the pin 16 in the direction opposite to the direction in which the cutter shaft 12 rotates by centrifugal action. Configured as follows.

図４に示すように、このように構成された本発明の剥離装置１０は、その回転部材１１が支持台２２により回転自在に支持される。図４における支持台２２は、方形状の台板２２ａと、その台板２２ａの後端に立設された支持板２２ｂと、台板２２ａの前端に立設された案内板２２ｃとを備える。回転部材１１は支持台２２における支持板２２ｂに図示しない軸受を介して回転自在に支持され、回転部材１１の支持板２２を挟んで後端側には第１プーリ２３が固定される。一方、駆動装置であるモータ２４の回転軸には第２プーリ２４ａが設けられ、この第２プーリ２４ａと第１プーリ２３との間にはベルト２６が架設される。従って、このベルト２６を介してモータ２４の回転軸の回転運動が伝達されて回転部材１１を回転駆動可能に構成される。なお、モータ２４は支持台２２の一部に取付けられる。   As shown in FIG. 4, in the peeling device 10 of the present invention configured as described above, the rotating member 11 is rotatably supported by a support base 22. The support base 22 in FIG. 4 includes a square base plate 22a, a support plate 22b erected at the rear end of the base plate 22a, and a guide plate 22c erected at the front end of the base plate 22a. The rotating member 11 is rotatably supported by a support plate 22b of the support base 22 via a bearing (not shown), and a first pulley 23 is fixed to the rear end side with the support plate 22 of the rotating member 11 interposed therebetween. On the other hand, a second pulley 24 a is provided on the rotating shaft of the motor 24 that is a driving device, and a belt 26 is provided between the second pulley 24 a and the first pulley 23. Therefore, the rotary motion of the rotary shaft of the motor 24 is transmitted through the belt 26 so that the rotary member 11 can be driven to rotate. The motor 24 is attached to a part of the support base 22.

モータ２４は図示しないコントローラによって供給される導電線Ａの径に応じてその回転速度が可変制御されるようになっており、例えば、導電線Ａの線径が細い場合には高い回転速度とし、その線径が太くなるに従いより低くなるように回転速度が設定される。そして、ノズル１１ａの前方に位置する案内板２２ｃには、導電線Ａを支持案内するガイド孔２２ｄが回転部材１１の中心軸と同軸に形成され、ノズル１１ａより引き出された導電線Ａはこのガイド孔２２ｄとノズル１１ａとで振れることなく支持されて前方に案内されるように構成される。   The rotation speed of the motor 24 is variably controlled according to the diameter of the conductive wire A supplied by a controller (not shown). For example, when the wire diameter of the conductive wire A is thin, the rotation speed is high. The rotation speed is set so as to decrease as the wire diameter increases. In the guide plate 22c located in front of the nozzle 11a, a guide hole 22d for supporting and guiding the conductive wire A is formed coaxially with the central axis of the rotating member 11, and the conductive wire A drawn from the nozzle 11a is guided by this guide. The hole 22d and the nozzle 11a are supported without being shaken and are guided forward.

次にこの剥離装置の作用を説明する。
この剥離装置１０には、導電線Ａを回転部材１１の後方から挿入し、ノズル１１ａの前端からカッタ１３により包囲された範囲、即ち刃部１３ａの側面を通して支持台２２のガイド孔２２ｄに挿通させ、その後図示しない例えば巻線装置へ所定の張力で供給（引き出される）する。駆動装置であるモータ２４が回転していないときには、回転部材１１は停止しており、板バネ２１の付勢力Ｇ（図２）によりカッタ１３は相互に最大限に開いた状態に維持される。このため、導電線Ａはカッタ１３の刃部１３ａ間を通り絶縁被膜が剥離されることなく図示しない巻線装置へ供給される。 Next, the operation of this peeling apparatus will be described.
In this peeling device 10, the conductive wire A is inserted from the rear of the rotating member 11, and is inserted into the guide hole 22 d of the support base 22 through the range surrounded by the cutter 13 from the front end of the nozzle 11 a, that is, the side surface of the blade portion 13 a. Thereafter, for example, it is supplied (drawn) with a predetermined tension to a winding device (not shown). When the motor 24 that is the driving device is not rotating, the rotating member 11 is stopped, and the cutters 13 are maintained in a mutually open state by the urging force G (FIG. 2) of the leaf spring 21. For this reason, the conductive wire A passes between the blade portions 13a of the cutter 13 and is supplied to a winding device (not shown) without peeling off the insulating coating.

例えば巻線装置からの指令により、或いは、所定量だけ導電線を通過させる度に絶縁被膜の剥離の要求がされると、モータ２４が導電線Ａの線径に対応した回転速度で回転し、その回転軸に設けられた第２プーリ２４ａ，ベルト２６及び第１プーリ２３を介して回転部材１１をフランジ１１ｂ，１１ｃと共に回転させ、それに付随するカッタ１３、カッタシャフト１２及び錘１４をその導電線Ａの周囲に公転させる。各錘１４は回転部材１１の回転速度に応じて板バネ２１による戻し方向の付勢に抗して各カッタシャフト１２を軸として半径方向外側に回転（自転）する。これによりカッタシャフト１２が回動（自転）し、各カッタ１３を導電線Ａに接触させ、その各刃部１３ａにより導電線Ａの外周面の絶縁被膜を螺旋状に剥離する。そして、例えば所定時間若しくは所定長さの分だけ絶縁被膜の剥離が完了するとモータ２４は停止され、回転部材１１は回転を停止し、板バネ２１の付勢力Ｇにより錘１４が戻り、カッタ１３は開放した初期位置に復帰する。   For example, when a command is issued from the winding device or a request for peeling of the insulating film is made each time a conductive wire is passed through a predetermined amount, the motor 24 rotates at a rotational speed corresponding to the wire diameter of the conductive wire A, The rotating member 11 is rotated together with the flanges 11b and 11c through the second pulley 24a, the belt 26 and the first pulley 23 provided on the rotating shaft, and the cutter 13, the cutter shaft 12 and the weight 14 associated therewith are connected to the conductive wires. Revolve around A. Each weight 14 rotates (rotates) radially outward about each cutter shaft 12 against the biasing of the return direction by the leaf spring 21 according to the rotational speed of the rotating member 11. As a result, the cutter shaft 12 rotates (rotates), the cutters 13 are brought into contact with the conductive wires A, and the insulating coating on the outer peripheral surface of the conductive wires A is spirally peeled off by the blade portions 13a. Then, for example, when the insulation coating is peeled off for a predetermined time or a predetermined length, the motor 24 is stopped, the rotation member 11 stops rotating, the weight 14 is returned by the biasing force G of the leaf spring 21, and the cutter 13 is Return to the opened initial position.

上記作動において、モータ２４の回転速度を上昇させれば錘１４が板バネ２１に抗してより半径方向外側に移動するため、各カッタ１３の刃部１３ａで形成する多角形（図３）の大きさがより小さくなる。そして、板バネ２１は、遠心力により回転しようとする方向と逆方向に錘１４を付勢するため、遠心力Ｆにより錘１４が回転しようとする力を板バネ２１が受止め、遠心力Ｆにより錘１４が回転しようとする力と板バネ２１の付勢力Ｇが釣合う状態までカッタシャフト１２を回動（自転）させる。従って、回転部材１１の回転速度を高めるとカッタシャフト１２の回動量が増加し、その前端に設けられたカッタ１３がより導電線Ａの軸線に近い位置まで移動することになる。よって、回転部材１１の回転速度を調整することで、各カッタ１３の刃部１３ａで形成する多角形の大きさを調整することができ、カッタ１３の切込み量を調整することができる。この結果、導電線Ａの線径に対応して回転部材１１の回転速度を変更調整することで、剥離作動中の導電線Ａにカッタ１３が過度に押圧されることを防止することができ、断線や導電部の多量な削り取り等を防止することができる。   In the above operation, if the rotational speed of the motor 24 is increased, the weight 14 moves further outward in the radial direction against the leaf spring 21. Therefore, the polygon (FIG. 3) formed by the blade portions 13a of the cutters 13 is used. The size becomes smaller. The leaf spring 21 urges the weight 14 in the direction opposite to the direction in which the leaf spring 21 is rotated by the centrifugal force. Therefore, the leaf spring 21 receives the force that the weight 14 is about to rotate by the centrifugal force F. As a result, the cutter shaft 12 is rotated (rotated) until the force to rotate the weight 14 and the biasing force G of the leaf spring 21 are balanced. Accordingly, when the rotational speed of the rotating member 11 is increased, the amount of rotation of the cutter shaft 12 increases, and the cutter 13 provided at the front end thereof moves to a position closer to the axis of the conductive wire A. Therefore, by adjusting the rotation speed of the rotating member 11, the size of the polygon formed by the blade portion 13a of each cutter 13 can be adjusted, and the cutting amount of the cutter 13 can be adjusted. As a result, by changing and adjusting the rotation speed of the rotating member 11 corresponding to the wire diameter of the conductive wire A, the cutter 13 can be prevented from being excessively pressed against the conductive wire A during the peeling operation. It is possible to prevent disconnection and a large amount of scraping of the conductive portion.

ここで、本発明に使用する板バネ２１は、従来用いられていた図６におけるコイルバネ３に比較して軽量であるにもかかわらず、剛性が高いという性質を有する。そして、板バネ２１の基端を固定して湾曲させ、その先端又はその先端と基端の中間部分をピン１６に接触させるので、回転部材１１を回転させることにより生じる遠心力により板バネ２１がピン１６を押しつける方向の力Ｇが増加したとしても、その遠心力によりこの板バネ２１自体が撓むようなことはない。このため、この板バネ２１がピン１６を介して錘１４を付勢する付勢力Ｇが変動するようなことはなく、回転部材１１の回転速度とカッタシャフト１２の回動量を比較的正確に比例させることができる。この結果、回転部材１１の回転速度を調整することにより、カッタシャフト１２に設けられたカッタ１３の位置を比較的正確に制御することが可能となり、導電線Ａが細い場合にもそれを断線することなく絶縁被膜を有効に剥離することができる。   Here, the leaf spring 21 used in the present invention has a property of high rigidity despite being lighter than the conventionally used coil spring 3 in FIG. Then, the base end of the leaf spring 21 is fixed and curved, and the tip or an intermediate portion between the tip and the base end is brought into contact with the pin 16, so that the leaf spring 21 is caused by the centrifugal force generated by rotating the rotating member 11. Even if the force G in the direction of pressing the pin 16 increases, the leaf spring 21 itself does not bend due to the centrifugal force. For this reason, the urging force G for urging the weight 14 via the pin 16 by the leaf spring 21 does not fluctuate, and the rotational speed of the rotating member 11 and the rotation amount of the cutter shaft 12 are proportional to each other relatively accurately. Can be made. As a result, by adjusting the rotation speed of the rotating member 11, the position of the cutter 13 provided on the cutter shaft 12 can be controlled relatively accurately, and even when the conductive wire A is thin, it is disconnected. Insulating coating can be effectively peeled off without any problems.

このカッタ１３の位置の制御を具体的に説明すると、例えば、カッタ１３の刃部１３ａで形成される図３に示す多角形への内接円の径が、導電線Ａの線径から絶縁皮膜分を差引いた径となるように、モータ２４の回転速度を設定すれば、導電線Ａの絶縁皮膜を剥離することができる。また、導電線Ａ自体の材質が硬い場合には、その内接円が導電線Ａの線径から絶縁皮膜分を差引いた径よりほんの若干小さくすることで、カッタ１３の刃部１３ａに微小な接触圧を持たせて導電線Ａと接触させることができ、その絶縁皮膜を効果的に剥離することができる。このように、導電線Ａの線径に対応してモータ２４の回転速度を変更することで、上記剥離作動中の導電線Ａにカッタ１３が過度に押圧されることを防止することができ、導電線Ａの断線や導電部の多量な削り取り等を防止しつつ柔らかい表面の樹脂層からなる絶縁被膜を少量の導電部とともに確実に剥離することができる。   The control of the position of the cutter 13 will be specifically described. For example, the diameter of the inscribed circle to the polygon shown in FIG. 3 formed by the blade portion 13a of the cutter 13 is changed from the wire diameter of the conductive wire A to the insulating film. If the rotational speed of the motor 24 is set so as to obtain a diameter obtained by subtracting the minutes, the insulating film of the conductive wire A can be peeled off. Further, when the material of the conductive wire A itself is hard, the inscribed circle is slightly smaller than the diameter obtained by subtracting the insulating film from the wire diameter of the conductive wire A, so that the blade portion 13a of the cutter 13 has a minute size. A contact pressure can be given and it can be made to contact with the conductive wire A, and the insulating film can be effectively peeled off. Thus, by changing the rotational speed of the motor 24 corresponding to the wire diameter of the conductive wire A, it is possible to prevent the cutter 13 from being excessively pressed against the conductive wire A during the peeling operation. The insulating coating made of a soft resin layer can be reliably peeled off together with a small amount of the conductive portion while preventing disconnection of the conductive wire A and a large amount of scraping of the conductive portion.

そして、本発明の剥離装置１０では、板バネ２１自体が遠心力により撓むようなことがないので、この板バネ２１が円板１８の外周より外側に著しく膨らむようなこともない。このため、支持台２２や剥離装置１０を収容する図示しないケースにこの板バネ２１が接触することはなく、板バネ２１が接触することに起因するカッタシャフト１２の回動量の変化を防止でき、その接触によりバネ２１及びピン１６が破損するような事態を回避することもできる。そして、板バネ２１を用いる本発明の剥離装置１０では、撓みと復元を繰り返すことによる疲労によりその板バネ２１が破壊するようなこともない。   And in the peeling apparatus 10 of this invention, since the leaf | plate spring 21 itself does not bend by a centrifugal force, this leaf | plate spring 21 does not swell significantly outside the outer periphery of the disc 18. FIG. For this reason, the leaf spring 21 does not come into contact with a case (not shown) that accommodates the support base 22 or the peeling device 10, and the change in the rotation amount of the cutter shaft 12 due to the contact with the leaf spring 21 can be prevented. A situation in which the spring 21 and the pin 16 are damaged by the contact can also be avoided. And in the peeling apparatus 10 of this invention using the leaf | plate spring 21, the leaf | plate spring 21 is not destroyed by the fatigue by repeating a bending and a decompression | restoration.

なお、上述した実施の形態では、また、カッタシャフト１２を３本設ける例を示したが、カッタシャフト１２の本数はこれに限定されず、１個のみ設けるものであっても良く、２本又は４本若しくは５本以上であっても良いが、理想的には導電線Ａを挟むように２個以上設けることが望ましい。   In the above-described embodiment, an example in which three cutter shafts 12 are provided has been described. However, the number of cutter shafts 12 is not limited thereto, and only one cutter shaft 12 may be provided. The number may be four or five or more, but ideally two or more are preferably provided so as to sandwich the conductive wire A therebetween.
