Description

本発明は、コアレスモータに使用するカップ型コイルを主に製造する巻線装置及び巻線方法に関するものである。 The present invention relates to a winding device and a winding method for mainly manufacturing a cup-type coil used in a coreless motor.

近年、コアレスモータにはカップ型コイルが用いられており、カップ型コイルは従来から公知の専用自動巻線機により製造されている。この自動巻線機は、コイル素材である線材を巻き取る巻治具と、巻治具に向けて線材を繰り出しながら巻治具の軸方向に往復動するノズルと、巻治具の軸方向の両側に離間して配置された一対の案内片を有するとしている（例えば、特許文献１参照。）。 In recent years, a cup-type coil has been used for a coreless motor, and the cup-type coil is manufactured by a conventionally known dedicated automatic winding machine. This automatic winding machine has a winding jig that winds a wire rod that is a coil material, a nozzle that reciprocates in the axial direction of the winding jig while feeding out the wire rod toward the winding jig, and an axial direction of the winding jig. It is said that it has a pair of guide pieces arranged apart from each other on both sides (see, for example, Patent Document 1).

この自動巻線機では、ノズルを巻治具の軸方向に往復させながら線材を繰り出し、この線材の繰り出しに応じて巻治具および案内片を同方向に回転させて、線材を巻治具上に巻き取る構成となっている。そして、巻治具の周囲に供給された線材は一対の案内片により、その巻治具の周囲において案内片を頂点とする三角波になるように構成されている。 In this automatic winding machine, the wire rod is unwound while reciprocating the nozzle in the axial direction of the winding jig, and the winding jig and the guide piece are rotated in the same direction according to the unwinding of the wire rod to wind the wire rod on the winding jig. It is configured to be wound up. The wire rod supplied around the winding jig is configured by a pair of guide pieces so as to form a triangular wave having the guide piece as the apex around the winding jig.

特開昭５５−１０００４５号公報Japanese Unexamined Patent Publication No. 55-100045

しかし、ノズルを巻治具の軸方向に直線的に往復させながら線材を繰り出し、巻治具の周囲において線材を三角波状にする上記従来の巻線装置では、案内片において線材は直ちに折り返されることに成り、その折り返される線材が膨らんで得られたカップ型コイルの両端における外径が拡大する不具合があった。 However, in the above-mentioned conventional winding device in which the wire rod is unwound while linearly reciprocating in the axial direction of the winding jig and the wire rod is formed into a triangular wave shape around the winding jig, the wire rod is immediately folded back at the guide piece. There was a problem that the outer diameters at both ends of the cup-shaped coil obtained by swelling the folded wire rod increased.

また、ノズルを巻治具の軸方向に直線的に往復させる装置は、ノズルの他に、ノズルを保持する保持具や、その保持具を往復移動させるレールや、移動機構を必要とし、直線的に往復移動するノズル周囲の部材の質量が増加して、その慣性力の増加によりノズルを素早く往復移動させることが困難となり、その往復移動を素早く行って、巻線に係る時間を短縮させるには限界が生じる不具合もあった。 In addition, a device that linearly reciprocates the nozzle in the axial direction of the winding jig requires a holder for holding the nozzle, a rail for reciprocating the holder, and a moving mechanism, and is linear. The mass of the member around the nozzle that reciprocates in the nozzle increases, and the increase in the inertial force makes it difficult to reciprocate the nozzle quickly. To perform the reciprocating movement quickly and shorten the time required for winding. There was also a problem that a limit was created.

更に、先に形成された三角波状の線材に隣接して新たな三角波状の線材を巻治具に巻回しようとすると、一対の案内片の回転速度と巻治具の回転速度を違え、例えば、巻治具が１回転する毎に一対の案内片を線材の太さ分だけ進角させる必要が生じる。 Further, when a new triangular wave-shaped wire is wound around the winding jig adjacent to the previously formed triangular wave-shaped wire, the rotation speed of the pair of guide pieces and the rotation speed of the winding jig are different, for example. Each time the winding jig makes one rotation, it becomes necessary to advance the pair of guide pieces by the thickness of the wire rod.

しかし、図１３に示す様に、一対の案内片２，２を線材３の太さ分だけ進角させつつ、ノズル５を巻治具４の軸方向に直線的に往復させながら線材３を三角波にしても、ノズル５は一対の案内片２，２の外側にまで移動する必要があることから、先に形成された三角波に隣接してノズル５が移動するとは限らない。 However, as shown in FIG. 13, the wire rod 3 is triangularly waved while the pair of guide pieces 2 and 2 are advanced by the thickness of the wire rod 3 and the nozzle 5 is linearly reciprocated in the axial direction of the winding jig 4. Even so, since the nozzle 5 needs to move to the outside of the pair of guide pieces 2 and 2, the nozzle 5 does not always move adjacent to the previously formed triangular wave.

このため、ノズル５を巻治具４の軸方向に往復移動させながら線材３を繰り出す従来の巻線機では、先の形成された三角波との間に隙間が生じ、巻治具４に巻回される線材３を隣接する線材に密着させる、いわゆる整列巻が比較的困難となる不具合がある。 For this reason, in a conventional winding machine that feeds out the wire rod 3 while reciprocating the nozzle 5 in the axial direction of the winding jig 4, a gap is generated between the nozzle 5 and the previously formed triangular wave, and the winding jig 4 is wound. There is a problem that it is relatively difficult to perform so-called aligned winding, in which the wire rod 3 is brought into close contact with the adjacent wire rod.

本発明の目的は、両端における外径の拡大が抑制されたカップ型コイルを得る巻線装置及び巻線方法を提供することにある。 An object of the present invention is to provide a winding device and a winding method for obtaining a cup-shaped coil in which expansion of the outer diameter at both ends is suppressed.

本発明の別の目的は、巻線に係る時間を短縮させ得る巻線装置及び巻線方法を提供することにある。 Another object of the present invention is to provide a winding device and a winding method capable of shortening the winding time.

本発明の更に別の目的は、巻治具に巻回される線材を隣接する線材に密着させ得る巻線装置及び巻線方法を提供することにある。 Yet another object of the present invention is to provide a winding device and a winding method capable of bringing a wire wound around a winding jig into close contact with an adjacent wire.

本発明は、円柱状を成し中心軸を中心として回転して線材を周囲に巻回する巻治具と、巻治具の軸方向の両側に離間して配置され巻治具と同方向に回転する一対の案内片と、案内片を頂点とする三角波となるように線材を巻治具の周囲に供給する線材供給手段とを備えた巻線装置の改良である。 The present invention is a winding jig that forms a columnar shape and rotates around a central axis to wind a wire rod around it, and a winding jig that is arranged at a distance from both sides in the axial direction and in the same direction as the winding jig. This is an improvement of a winding device including a pair of rotating guide pieces and a wire rod supply means for supplying the wire rod around the winding jig so as to form a triangular wave having the guide piece as the apex.

その特徴ある点は、線材供給手段が、巻治具の中心軸に直交する直交軸又はその直交軸に平行な平行軸を中心に回転する回転体と、回転体の周囲に設けられ線材を供給するノズルと、回転体を正逆回転させる正逆回転手段とを備え、正逆回転手段は、一対の案内片が一回転する毎に回転体を正転及び逆転させて直交軸又は平行軸を中心としてノズルを一回揺動させるように構成されたところにある。 The characteristic point is that the wire rod supply means is provided around a rotating body that rotates around an orthogonal axis orthogonal to the central axis of the winding jig or a parallel axis parallel to the orthogonal axis, and a wire rod is supplied around the rotating body. It is provided with a nozzle for rotating the rotating body and a forward / reverse rotating means for rotating the rotating body in the forward / reverse direction. It is located where the nozzle is configured to swing once as the center.

また、別の本発明は、巻治具と、その巻治具の軸方向の両側に離間して配置された一対の案内片を同方向に回転させ、ノズルから繰り出される線材を一対の案内片を頂点とする三角波となるように巻治具の周囲に巻回する巻線方法の改良である。 Further, in another invention, the winding jig and a pair of guide pieces arranged apart from each other on both sides in the axial direction of the winding jig are rotated in the same direction, and the wire rod drawn out from the nozzle is a pair of guide pieces. This is an improvement of the winding method of winding around the winding jig so as to form a triangular wave having a peak.

その特徴ある点は、一対の案内片が一回転する毎に、巻治具の中心軸に直交する直交軸又はその直交軸に平行な平行軸を中心に、ノズルを一回揺動させるところにある。 The characteristic point is that each time a pair of guide pieces make one rotation, the nozzle is swung once around an orthogonal axis orthogonal to the central axis of the winding jig or a parallel axis parallel to the orthogonal axis. is there.

そして、巻線装置が巻治具の先端を支持する支治具と、その支持具を巻治具と共に回転させる支持具回転手段とを備える場合、その巻線方法において、巻治具の先端を支治具により支持させることが好ましい。 When the winding device includes a support jig for supporting the tip of the winding jig and a support rotating means for rotating the support together with the winding jig, the tip of the winding jig is used in the winding method. It is preferable to support it with a support jig.

また、巻治具が先端に設けられた支持ロッドと支持具の双方に巻治具に巻回された線材の端部が係止する係止手段をそれぞれ設け、その係止手段に巻治具に巻回された線材の端部を係止させることもできる。 Further, both the support rod and the support tool provided with the winding jig at the tip are provided with locking means for locking the end of the wire wound around the winding jig, and the winding jig is used for the locking means. It is also possible to lock the end of the wire wound around the wire.

本発明の巻線装置及び巻線方法では、ノズルを揺動させながら線材を繰り出すので、一方の案内片に掛け回された線材は、ノズルと共に巻治具の回転方向前方又は後方に繰り出された後に他の案内片側に導かれ、他の案内片側にノズルが達した段階で、その線材は一方の案内片において初めて折り返されることに成る。 In the winding device and winding method of the present invention, the wire rod is fed while swinging the nozzle, so that the wire rod hung on one of the guide pieces is fed forward or backward in the rotation direction of the winding jig together with the nozzle. Later, when it is guided to the other guide piece side and the nozzle reaches the other guide piece side, the wire rod is folded back for the first time in one guide piece.

このように、案内片に掛け回された線材を巻治具の回転方向前方又は後方に一旦導いた後に他の案内片側に導いて線材を折り返すと、その折り返される線材の膨らみは巻治具の回転方向に向かう。 In this way, when the wire rod hung on the guide piece is once guided forward or backward in the rotation direction of the winding jig and then guided to the other guide piece side to fold the wire rod, the bulge of the folded wire rod becomes the winding jig. Go in the direction of rotation.

このため、ノズルを巻治具の軸方向に往復移動させて、案内片において線材を巻治具の半径方向外側に向けて直ちに折り返す従来に比較して、折り返される線材の巻治具の半径方向外側への膨らみを少なくすることができる。よって、本発明では、両端における外径の拡大が抑制されたコイルを得ることが可能となる。 For this reason, the nozzle is reciprocated in the axial direction of the winding jig, and the wire rod is immediately folded back toward the outside in the radial direction of the winding jig in the guide piece, as compared with the conventional case where the wire rod is folded back in the radial direction of the winding jig. The bulge to the outside can be reduced. Therefore, in the present invention, it is possible to obtain a coil in which expansion of the outer diameter at both ends is suppressed.

また、ノズルを揺動させる本発明では、ノズルを往復移動させる従来のものに比較して、ノズル周囲の慣性モーメントを小さくすることができるので、ノズルの揺動を比較的素早く行うことが可能となる。よって、本発明では、従来のものに比較して、巻線に係る時間を短縮させることが可能となる。 Further, in the present invention in which the nozzle is swung, the moment of inertia around the nozzle can be reduced as compared with the conventional one in which the nozzle is reciprocated, so that the nozzle can be swung relatively quickly. Become. Therefore, in the present invention, it is possible to shorten the time required for winding as compared with the conventional one.

更に、巻治具及び案内片を回転させ、ノズルを揺動させながら線材を繰り出す本発明では、ノズルから新たに繰り出される線材を一方の案内片に掛け回した後に、その線材は巻治具の回転方向前方又は後方に案内され、他の案内片側にノズルが達した段階で、その先に巻回された線材に隣接して密着することになる。よって、本発明では、巻治具に巻回される線材を隣接する線材に密着させる、いわゆる整列巻が容易となる。 Further, in the present invention in which the winding jig and the guide piece are rotated and the wire rod is unwound while swinging the nozzle, the wire rod newly unwound from the nozzle is hung around one guide piece, and then the wire rod is of the winding jig. It is guided forward or backward in the direction of rotation, and when the nozzle reaches the other guide side, it comes into close contact with the wire wound ahead of the nozzle. Therefore, in the present invention, so-called aligned winding, in which the wire rod wound around the winding jig is brought into close contact with the adjacent wire rod, becomes easy.

次に、本発明を実施するための最良の形態を図面に基づいて説明する。 Next, the best mode for carrying out the present invention will be described with reference to the drawings.

本発明の巻線装置を図１及び図２に示す。ここで、互いに直交するＸ、Ｙ、Ｚの３軸を設定し、Ｘ軸が水平前後方向、Ｙ軸が水平横方向、Ｚ軸が垂直方向に延びるものとして本発明の巻線装置１０について説明する。 The winding device of the present invention is shown in FIGS. 1 and 2. Here, the winding device 10 of the present invention will be described assuming that three axes of X, Y, and Z orthogonal to each other are set, the X axis extends in the horizontal front-rear direction, the Y axis extends in the horizontal horizontal direction, and the Z axis extends in the vertical direction. To do.

本発明の巻線装置１０は、円柱状を成し中心軸を中心として回転して線材１１を周囲に巻回する巻治具１２を備える。即ち、本発明の巻線装置１０は、円柱状を成す巻治具１２と、その巻治具１２の中心軸を中心としてその巻治具１２を回転させる治具回転手段１３とを備える。 The winding device 10 of the present invention includes a winding jig 12 that forms a columnar shape, rotates around a central axis, and winds a wire rod 11 around it. That is, the winding device 10 of the present invention includes a winding jig 12 forming a columnar shape and a jig rotating means 13 for rotating the winding jig 12 around the central axis of the winding jig 12.

この治具回転手段１３は、巻治具１２が先端に同軸に設けられた円柱状を成す支持ロッド１４と、この支持ロッド１４を回転させるサーボモータ１６と、このサーボモータ１６が搭載された可動台１７とを備えるものとし、可動台１７には一対の支持壁１８，１８が立設される。一対の支持壁１８，１８には、中空の外ロッド１９が回転可能に架設され、支持ロッド１４は外ロッド１９に貫通して同軸に回転可能に設けられる。 The jig rotating means 13 includes a cylindrical support rod 14 having a winding jig 12 coaxially provided at the tip thereof, a servomotor 16 for rotating the support rod 14, and a movable servomotor 16 mounted on the servomotor 16. A base 17 is provided, and a pair of support walls 18 and 18 are erected on the movable base 17. A hollow outer rod 19 is rotatably installed on the pair of support walls 18 and 18, and the support rod 14 is provided so as to penetrate the outer rod 19 and rotatably coaxially.

サーボモータ１６はその回転軸１６ａが支持ロッド１４と同軸になるように可動台１７にアクチュエータ２１を介して取付けられ、回転軸１６ａと支持ロッド１４は継ぎ手２０を介して連結される。そして、支持ロッド１４の先端に同軸に設けられた円柱状の巻治具１２は、サーボモータ１６が駆動して支持ロッド１４が回転することにより、同時にその中心軸を中心として回転するように構成される。 The servomotor 16 is attached to the movable base 17 via an actuator 21 so that its rotating shaft 16a is coaxial with the support rod 14, and the rotating shaft 16a and the support rod 14 are connected via a joint 20. The columnar winding jig 12 coaxially provided at the tip of the support rod 14 is configured to rotate about the central axis of the support rod 14 at the same time as the servomotor 16 drives the support rod 14. Will be done.

サーボモータ１６と可動台１７との間に設けられたアクチュエータ２１は、回転軸１６ａの軸方向に延びて可動台１７に取付けられた細長い箱形ハウジング２１ｄと、そのハウジング２１ｄ内部に長手方向に伸びて設けられサーボサーボモータ２１ａによって回動駆動されるボールネジ２１ｂと、このボールネジ２１ｂに螺合して平行移動する従動子２１ｃ等によって構成され、この従動子２１ｃにサーボモータ１６が取付けられる。 The actuator 21 provided between the servomotor 16 and the movable base 17 extends in the axial direction of the rotating shaft 16a and extends in the longitudinal direction into the elongated box-shaped housing 21d attached to the movable base 17 and the inside of the housing 21d. The servomotor 16 is attached to the ball screw 21b which is provided and is rotationally driven by the servo servomotor 21a, and the actuator 21c which is screwed into the ball screw 21b and moves in parallel.

よって、このアクチュエータ２１は、そのサーボモータ２１ａが駆動することにより回転するボールネジ２１ｂにより従動子２１ｃが巻治具１２を回転させるサーボモータ１６とともに移動するように構成される。そして、サーボモータ１６が移動すると、その回転軸１６ａに継ぎ手２０を介して連結された支持ロッド１４が巻治具１２とともに、巻治具１２の軸方向に移動するように構成される。 Therefore, the actuator 21 is configured such that the follower 21c moves together with the servomotor 16 that rotates the winding jig 12 by the ball screw 21b that rotates when the servomotor 21a is driven. Then, when the servomotor 16 moves, the support rod 14 connected to the rotating shaft 16a via the joint 20 is configured to move together with the winding jig 12 in the axial direction of the winding jig 12.

図１及び図２に示す様に、この巻線装置１０は、巻治具１２の先端を支持する支持具３２と、その支持具３２を巻治具１２と共に回転させる支持具回転手段３３が設けられる。支持具３２は、支持ロッド１４と同様の断面円形を成す円柱状部材であって、その支持具３２を回転させる支持具回転手段３３は、巻治具１２の中心をＹ軸方向に通過する仮想線を対称線として、支持ロッド１４を回転させる治具回転手段１３と対称構造を成して構成される。 As shown in FIGS. 1 and 2, the winding device 10 is provided with a support 32 for supporting the tip of the winding jig 12 and a support rotating means 33 for rotating the support 32 together with the winding jig 12. Be done. The support 32 is a columnar member having a circular cross section similar to the support rod 14, and the support rotating means 33 for rotating the support 32 passes through the center of the winding jig 12 in the Y-axis direction. The line is a symmetrical line, and the support rod 14 is formed to have a symmetrical structure with the jig rotating means 13 for rotating the support rod 14.

このように、支持具回転手段３３は治具回転手段１３と対称構造を成して構成されるので、治具回転手段１３を構成する部材の符号に「２０」を加えて、支持具回転手段３３を構成する部材の符号とし、この支持具回転手段３３における詳細な説明を省略する。 As described above, since the support rotating means 33 is configured to have a symmetrical structure with the jig rotating means 13, "20" is added to the code of the member constituting the jig rotating means 13 to add the support rotating means 13. The reference numerals are given to the members constituting the 33, and detailed description of the support rotating means 33 will be omitted.

そして、支持具回転手段３３におけるアクチュエータ４１は、そのサーボモータ４１ａが駆動することにより、支持具３２を回転させるサーボモータ３６を移動させ、それとともに移動する支持具３２を巻治具１２の先端に当接させて支持させ、又は巻治具１２の先端に当接させた支持具３２を巻治具１２から離間させて、巻治具１２の支持を解除させるように構成される。 Then, the actuator 41 in the support tool rotating means 33 moves the servomotor 36 that rotates the support tool 32 by being driven by the servomotor 41a, and the support tool 32 that moves with the servomotor 32 is placed on the tip of the winding jig 12. The support 32 that is brought into contact with the winding jig 12 or brought into contact with the tip of the winding jig 12 is separated from the winding jig 12 to release the support of the winding jig 12.

また、巻治具１２の先端に当接させた支持具３２は、巻治具１２のぶれを防止することになるけれども、その状態で支持具回転手段３３におけるサーボモータ３６が駆動してその回転軸３６ａが回転することにより、支持具３２は、巻治具１２と同期して、その巻治具１２と同方向に同一の速度で回転するように構成される。 Further, the support 32 brought into contact with the tip of the winding jig 12 prevents the winding jig 12 from shaking, but in that state, the servomotor 36 in the support rotating means 33 is driven to rotate the support tool 32. By rotating the shaft 36a, the support 32 is configured to rotate in the same direction as the winding jig 12 at the same speed in synchronization with the winding jig 12.

また、巻治具１２が先端に設けられた支持ロッド１４と支持具３２の双方には、巻治具１２に巻回された線材１１の端部が係止する係止手段である絡げピン６０が、その巻治具１２の近傍においてそれぞれ設けられる。この絡げピン６０は、カップ型コイル９（図１２）を構成する複数のコイル９ａの数だけ、支持ロッド１４と支持具３２の双方に、その周方向に等角度に設けられる。 Further, a entanglement pin, which is a locking means for locking the end portion of the wire rod 11 wound around the winding jig 12, to both the support rod 14 and the support tool 32 provided with the winding jig 12 at the tip. 60s are provided in the vicinity of the winding jig 12. The entanglement pins 60 are provided on both the support rod 14 and the support tool 32 at equal angles in the circumferential direction by the number of the plurality of coils 9a constituting the cup-shaped coil 9 (FIG. 12).

図１２に示す様に、この実施の形態では、三つのコイル９ａによりカップ型コイル９が構成されるものであるので、支持ロッド１４と支持具３２の双方に、絡げピン６０は周方向に１２０度毎に設けられる場合を示す。この絡げピン６０は、線材１１が実際絡げられるものと、その線材１１を巻治具１２に案内するためのものの二種類が、支持ロッド１４と支持具３２の双方に、軸方向に並んで設けられる場合を示す。 As shown in FIG. 12, in this embodiment, since the cup-shaped coil 9 is formed by the three coils 9a, the entanglement pins 60 are arranged in the circumferential direction on both the support rod 14 and the support tool 32. The case where it is provided every 120 degrees is shown. Two types of the entanglement pin 60, one in which the wire rod 11 is actually entwined and one for guiding the wire rod 11 to the winding jig 12, are arranged in the axial direction on both the support rod 14 and the support tool 32. Indicates the case where it is provided in.

即ち、支持ロッド１４と支持具３２の双方には、巻治具１２の近傍において絡げピン６０が軸方向に並んで二列になって、周方向に１２０度毎に設けられ、計６本の絡げピン６０が支持ロッド１４と支持具３２の双方にそれぞれ設けられるものとする。 That is, both the support rod 14 and the support tool 32 are provided with entwining pins 60 arranged in two rows in the vicinity of the winding jig 12 in the axial direction at every 120 degrees in the circumferential direction, for a total of six. It is assumed that the entanglement pin 60 is provided on both the support rod 14 and the support tool 32, respectively.

図１及び図２に戻って、この巻線装置１０は、巻治具１２の軸方向の両側に離間して配置されて巻治具１２と同方向に回転する一対の案内片６１，６１を備える。即ち、本発明の巻線装置１０は、巻治具１２の両側に配置された一対の案内片６１，６１と、その巻治具１２の中心軸を中心としてその一対の案内片６１，６１を回転させる片回転手段６２を備える。 Returning to FIGS. 1 and 2, the winding device 10 has a pair of guide pieces 61, 61 which are arranged apart from each other on both sides of the winding jig 12 in the axial direction and rotate in the same direction as the winding jig 12. Be prepared.

Since these have the same structure in the jig rotating means 13 and the support rotating means 33, those in the jig rotating means 13 will be described as a representative.

案内片６１が先端に設けられた保持具６４の基端は折り曲げられて円板６３の回転半径方向外側に向かって伸びる操作片６４ｂが形成される。保持具６４の基端が枢支された円板６３と操作片６４ｂの間には弾性体であるコイルスプリング６８が介装され、円板６３と操作片６４ｂの間の間隔を拡大しようとするコイルスプリング６８の付勢力により、保持具６４の先端は巻治具１２側に傾動しようとする付勢力が生じ、その先端に設けられた案内片６１を巻治具１２の周囲に接触させるように構成される（図１）。 The base end of the holder 64 provided with the guide piece 61 at the tip thereof is bent to form an operation piece 64b extending outward in the radial direction of the disk 63. A coil spring 68, which is an elastic body, is interposed between the disk 63 to which the base end of the holder 64 is pivotally supported and the operation piece 64b, and attempts to increase the distance between the disk 63 and the operation piece 64b. Due to the urging force of the coil spring 68, the tip of the holder 64 is urged to tilt toward the winding jig 12, so that the guide piece 61 provided at the tip is brought into contact with the periphery of the winding jig 12.

これらは離間手段６９を構成するものであって、図におけるアクチュエータ６９ｂは流体の給排によりロッド６９ｂａを本端部６９ｂｂから突出させ又はそのロッド６９ｂａを本体部６９ｂｂに没入させる流体圧シリンダが用いられ、そのロッド６９ｂａが巻治具１２の軸方向に平行になるように本端部６９ｂｂが可動台１７に取付けられ、そのロッド６９ｂａの突出端に操作板６９ａが取付けられるものとする。 These constitute the separating means 69, and the actuator 69b in the figure uses a fluid pressure cylinder in which the rod 69ba is projected from the main end portion 69bb or the rod 69ba is immersed in the main body portion 69bb by supplying and discharging the fluid. It is assumed that the main end portion 69bb is attached to the movable base 17 so that the rod 69ba is parallel to the axial direction of the winding jig 12, and the operation plate 69a is attached to the protruding end of the rod 69ba.

When they are separated from each other, the distance between the guide pieces 61 and 61 that they support separately in the axial direction of the winding jig 12 is shortened. Therefore, each of the actuators 22 and 42 provided on the base 10a is configured to be able to change the height of the triangular wave obtained with the guide piece 61 as the apex when the wire rod 11 is wound around the winding jig 12.

If the locking pin 94 in which the wire rod 11 is entwined is moved by projecting the wire rod 11 from the main body portion 93b or immersing it in the main body portion 93b, the wire rod 11 extending from the locking pin 94 is torn off in the middle. Is configured to be able to.

次に、このような巻線装置を用いた本発明の巻線方法を説明する。 Next, the winding method of the present invention using such a winding device will be described.

本発明の巻線方法では、先ず、図４に示すように、線材１１を図示しない線材供給源から回転体７１におけるガイド筒７１ｄに通過させ、ガイド筒７１ｄの先端から繰り出された線材１１をノズル７２に通過させる。このようにノズル７２から繰り出された線材１１を、図２に示す仮止め具９２における係止ピン９４に絡げておく。 In the winding method of the present invention, first, as shown in FIG. 4, the wire rod 11 is passed from a wire rod supply source (not shown) to the guide cylinder 71d of the rotating body 71, and the wire rod 11 unwound from the tip of the guide cylinder 71d is nozzleed. Pass through 72. The wire rod 11 drawn out from the nozzle 72 in this way is entwined with the locking pin 94 in the temporary fixing tool 92 shown in FIG.

次に、従動子２２ｃ，４２ｃに可動台１７，３７が設けられたそれぞれのアクチュエータ２２，４２により、一対の片回転手段６２，６２をそれぞれ離間又は接近させ、それらが別々に支持する案内片６１，６１の巻治具１２の軸方向における間隔を変更させて、得ようとするカップ型コイル９の長さＬ（図１２）に等しくさせる。 Next, the pair of one-sided rotating means 62 and 62 are separated or brought close to each other by the actuators 22 and 42 provided with the movable bases 17 and 37 on the jigs 22c and 42c, and the guide pieces 61 that support them separately. , 61 The spacing in the axial direction of the winding jig 12 is changed so that it is equal to the length L (FIG. 12) of the cup-shaped coil 9 to be obtained.

そして、治具回転手段１３及び支持具回転手段３３におけるそれぞれ別のアクチュエータ２１，４１により、巻治具１２と支持具３２を互いに接近させ、支持具３２の先端を巻治具１２の先端に当接させる。 Then, the winding jig 12 and the support 32 are brought close to each other by the separate actuators 21 and 41 in the jig rotating means 13 and the support rotating means 33, and the tip of the support 32 is brought into contact with the tip of the winding jig 12. Make contact.

次に、治具回転手段１３又は支持具回転手段３３における支持ロッド１４又は支持具３２を回転させて、それらのいずれかに設けられた絡げピン６０をノズル７２に対向させる。 Next, the support rod 14 or the support 32 in the jig rotation means 13 or the support rotation means 33 is rotated so that the entanglement pin 60 provided in any of them faces the nozzle 72.

この実施の形態では、巻初めの線材１１を支持具３２に設けられた絡げピン６０に絡げ、巻終わりの線材１１を支持ロッド１４に設けられた絡げピン６０に絡げるものとして説明する。 In this embodiment, the wire rod 11 at the beginning of winding is entwined with the entanglement pin 60 provided on the support 32, and the wire rod 11 at the end of winding is entwined with the entanglement pin 60 provided on the support rod 14. explain.

このため、支持具回転手段３３における支持具３２に設けられた絡げピン６０をノズル７２に対向させ、ノズル移動手段８０によりそのノズル７２を支持具３２に設けられた絡げピン６０の周囲に周回させ、ノズル７２から繰り出される線材１１を巻初めの線材１１としてその絡げピン６０に絡げる。 Therefore, the entanglement pin 60 provided on the support 32 in the support rotation means 33 is opposed to the nozzle 72, and the nozzle 72 is placed around the entanglement pin 60 provided on the support 32 by the nozzle moving means 80. The wire rod 11 unwound from the nozzle 72 is entwined with the entwining pin 60 as the wire rod 11 at the beginning of winding.

この時、支持ロッド１４又は支持具３２の軸方向に並んで絡げピン６０を二列に設けたこの実施の形態では、二列に設けられた絡げピン６０の、巻治具１２から離れた側の絡げピン６０に線材１１を絡げるものとする。 At this time, in this embodiment in which the entanglement pins 60 are provided in two rows side by side in the axial direction of the support rod 14 or the support tool 32, the entanglement pins 60 provided in the two rows are separated from the winding jig 12. It is assumed that the wire rod 11 is entwined with the entanglement pin 60 on the side.

そして、その後に、仮止め具９２における流体圧シリンダ９３の出没ロッド９３ａを本体部９３ｂに没入させて線材１１が絡げられた係止ピン９４を移動させ、それにより、その係止ピン９４から延びる線材１１を絡げピン６０の近傍において引き千切る。 Then, after that, the infestation rod 93a of the fluid pressure cylinder 93 in the temporary fixing tool 92 is immersed in the main body portion 93b to move the locking pin 94 in which the wire rod 11 is entwined, thereby moving the locking pin 94 from the locking pin 94. The extending wire 11 is entwined and torn off in the vicinity of the pin 60.

次に巻線となるけれども、先ず、片回転手段６２により一対の案内片６１，６１を回転させるとともに、ノズル７２が設けられた回転体７１を移動板７０ｂとともに移動させて図６に示すスタート位置にする。 Next, although it becomes a winding, first, the pair of guide pieces 61 and 61 are rotated by the one-sided rotating means 62, and the rotating body 71 provided with the nozzle 72 is moved together with the moving plate 70b to move the start position shown in FIG. To.

移動板７０ｂのスタート位置までの移動過程において、ノズル７２から繰り出される線材１１を巻治具１２の周囲に案内し、ノズル７２が設けられた回転体７１の回転中心を、一対の案内片６１，６１の中間であって、巻治具１２の回転中心に直交する直交軸Ｄに一致させ又はその直交軸Ｄに平行な平行軸に一致させる。 In the process of moving the moving plate 70b to the start position, the wire rod 11 unwound from the nozzle 72 is guided around the winding jig 12, and the rotation center of the rotating body 71 provided with the nozzle 72 is guided by the pair of guide pieces 61, It is in the middle of 61 and coincides with the orthogonal axis D perpendicular to the rotation center of the winding jig 12, or coincides with the parallel axis parallel to the orthogonal axis D.

そして、ノズル用サーボモータ７４により回転体７１を回転させ、回転体７１に設けられたノズル７２を巻治具１２の軸方向の端部にまで揺動させ、そのノズル７２を支持ロッド１４側の案内片６１の外側に位置させる。 Then, the rotating body 71 is rotated by the nozzle servomotor 74, the nozzle 72 provided on the rotating body 71 is swung to the axial end of the winding jig 12, and the nozzle 72 is on the support rod 14 side. It is located outside the guide piece 61.

そして、巻治具１２の中心軸Ｃを中心として一対の案内片６１，６１をそれぞれ回転させて、支持ロッド１４側の案内片６１をノズル７２に対向させ、支持具３２側の案内片６１をノズル７２から遠ざける。それとともに、線材１１が絡げられた絡げピン６０がノズル７２から離れた位置になるように、その絡げピン６０が設けられた支持具３２を回転させる。 Then, the pair of guide pieces 61 and 61 are rotated around the central axis C of the winding jig 12, and the guide piece 61 on the support rod 14 side faces the nozzle 72, and the guide piece 61 on the support tool 32 side is moved. Move away from the nozzle 72. At the same time, the support 32 provided with the entanglement pin 60 is rotated so that the entanglement pin 60 to which the wire rod 11 is entwined is located at a position away from the nozzle 72.

このようにして、図６に示すように、線材１１が絡げられた絡げピン６０からノズル７２に延びる線材１１が、支持具３２側の案内片６１から支持ロッド１４側の案内片６１にまで達するように、巻治具１２の周囲に斜めに半回転ほど掛け回す。この図６に示すような位置をスタート位置とする。 In this way, as shown in FIG. 6, the wire rod 11 extending from the entanglement pin 60 to which the wire rod 11 is entwined to the nozzle 72 is transferred from the guide piece 61 on the support tool 32 side to the guide piece 61 on the support rod 14 side. It is hung diagonally about half a turn around the winding jig 12 so as to reach the above. The position as shown in FIG. 6 is set as the start position.

この様な図６に示すスタート位置から、巻治具１２と一対の案内片６１，６１とを巻治具１２の中心軸Ｃを回転中心として、図中に示す矢印方向に同時回転させながら、正逆回転手段７３によりノズル７２を揺動させる。ノズル７２の揺動はノズル用サーボモータ７４により行われ、巻治具１２の中心軸Ｃを回転中心として一対の案内片６１，６１が一回転したときに、ノズル７２が１回揺動する速度とされる。 From the start position shown in FIG. 6, the winding jig 12 and the pair of guide pieces 61, 61 are simultaneously rotated around the central axis C of the winding jig 12 in the direction of the arrow shown in the drawing. The nozzle 72 is swung by the forward / reverse rotation means 73. The swing of the nozzle 72 is performed by the servomotor 74 for the nozzle, and the speed at which the nozzle 72 swings once when the pair of guide pieces 61 and 61 make one rotation with the central axis C of the winding jig 12 as the center of rotation. It is said that.

このため、図７に示す様に、スタート位置から一対の案内片６１，６１と巻治具１２とが９０度回転すると、揺動するノズル７２はコイル長さの半分の位置まで移動し、線材１１が巻治具１２に４分の１周巻きつけられる。 Therefore, as shown in FIG. 7, when the pair of guide pieces 61, 61 and the winding jig 12 rotate 90 degrees from the start position, the swinging nozzle 72 moves to a position half the coil length, and the wire rod. 11 is wound around the winding jig 12 in a quarter turn.

一対の案内片６１，６１と巻治具１２とがそれから更に９０度回転し、それらがスタート位置から１８０度回転すると、図８に示すように一対の案内片６１，６１の左右位置および上下位置が入れ代わり、揺動するノズル７２は折り返し位置まで移動し、線材１１が巻治具１２に２分の１周巻きつけられる。 When the pair of guide pieces 61, 61 and the winding jig 12 are further rotated by 90 degrees and they are rotated by 180 degrees from the start position, the left and right positions and the vertical positions of the pair of guide pieces 61, 61 are as shown in FIG. The swinging nozzle 72 moves to the folded position, and the wire rod 11 is wound around the winding jig 12 in half.

更に同方向に巻治具１２と一対の案内片６１，６１とを回転し続けると今度はノズル７２は逆方向に揺動を始め、線材１１が他方の案内片６１の外側に引っ掛かって折り返される。そして、図９に示す様に、スタート位置から一対の案内片６１，６１と巻治具１２が２７０度回転すると、線材１１は巻治具１２上に４分の３周巻きつけられる。 Further, when the winding jig 12 and the pair of guide pieces 61 and 61 continue to rotate in the same direction, the nozzle 72 starts swinging in the opposite direction, and the wire rod 11 is caught on the outside of the other guide piece 61 and folded back. .. Then, as shown in FIG. 9, when the pair of guide pieces 61, 61 and the winding jig 12 rotate 270 degrees from the start position, the wire rod 11 is wound around the winding jig 12 by three quarters.

また、巻治具１２と一対の案内片６１，６１がスタート位置から３６０度回転すると、図６に示すスタート位置であってかつ揺動するノズル７２の折り返し点に戻る。そして、２回目にスタート位置に戻ってきた線材１１は、案内片６１において折り返され、その後もそのまま前述と同じ動作が繰り返されることになる。 Further, when the winding jig 12 and the pair of guide pieces 61, 61 rotate 360 degrees from the start position, the nozzle 72 returns to the turning point at the start position shown in FIG. 6 and swings. Then, the wire rod 11 that has returned to the start position for the second time is folded back at the guide piece 61, and the same operation as described above is repeated as it is thereafter.

このように、上記巻線動作が繰り返されると、巻治具１２の周囲に斜めに供給された線材１１は一対の案内片６１，６１により順次折り返され、その巻治具１２の周囲において案内片６１，６１を頂点とする三角波状に巻回されることになる。 When the winding operation is repeated in this way, the wire rod 11 diagonally supplied around the winding jig 12 is sequentially folded back by the pair of guide pieces 61, 61, and the guide pieces are sequentially folded around the winding jig 12. It will be wound in a triangular wave shape with 61 and 61 as vertices.

しかし、巻治具１２と一対の案内片６１，６１の回転数や回転速度を完全に一致させると、２回目の折り返し時に、１回目の線材１１上に２回目の線材１１が重なって巻き取られる不具合が生じる。このため、１回目の線材１１を巻き取った後には、２回目の線材１１を巻治具１２の周方向にずらす必要がある。 However, if the rotation speeds and rotation speeds of the winding jig 12 and the pair of guide pieces 61, 61 are completely matched, the second wire rod 11 overlaps the first wire rod 11 and is wound up at the time of the second folding. Problems occur. Therefore, after the first wire rod 11 is wound, it is necessary to shift the second wire rod 11 in the circumferential direction of the winding jig 12.

この実施の形態では、案内片６１の先端を巻治具１２の回転方向後方に向けて巻治具１２の外周に接触させているので、１回目の線材１１を巻き取った後、２回目の線材１１が来た時には、線材１１の太さ分だけ一対の案内片６１，６１の回転に対して巻治具１２の回転を遅らせる。 In this embodiment, since the tip of the guide piece 61 is brought into contact with the outer periphery of the winding jig 12 toward the rear in the rotation direction of the winding jig 12, the wire rod 11 is wound for the first time and then for the second time. When the wire rod 11 arrives, the rotation of the winding jig 12 is delayed with respect to the rotation of the pair of guide pieces 61, 61 by the thickness of the wire rod 11.

即ち、図示しないコントローラは、一対の案内片６１，６１が１回転する毎に、巻き取る線材１１の線径分だけ巻治具１２を遅角させて、線材１１が重なって巻治具１２上に巻き取られることの無いように、一対の案内片６１，６１の回転に対して、巻治具１２の回転数及び回転速度を僅かに小さくするように制御する。なお、遅角の程度は、図示しないコントローラにより、線材１１の太さに合わせて設定することになる。 That is, in the controller (not shown), each time the pair of guide pieces 61, 61 make one rotation, the winding jig 12 is retarded by the wire diameter of the wire rod 11 to be wound, and the wire rods 11 overlap each other on the winding jig 12. The rotation speed and rotation speed of the winding jig 12 are controlled to be slightly reduced with respect to the rotation of the pair of guide pieces 61, 61 so as not to be wound around. The degree of retard angle is set according to the thickness of the wire rod 11 by a controller (not shown).

このように、巻治具１２が１回転する毎に、線材１１の太さに対応する角度分だけ一対の案内片６１，６１に対して巻治具１２の回転角度を遅角させつつ、更に巻治具１２と一対の案内片６１，６１を回転させる巻線作業を継続させる。 In this way, each time the winding jig 12 rotates, the rotation angle of the winding jig 12 is retarded with respect to the pair of guide pieces 61, 61 by an angle corresponding to the thickness of the wire rod 11, and further. The winding operation for rotating the winding jig 12 and the pair of guide pieces 61, 61 is continued.

すると、図１０に示す様に、先に巻回された線材１１に隣接して新たに線材１１が巻治具１２の周囲に巻回されることになり、この巻線作業の継続により、巻治具１２の周囲に斜めに供給された線材１１は一対の案内片６１，６１により順次折り返され、その巻治具１２の周囲において案内片６１，６１を頂点として互いに隣接する三角波状の線材１１の集合から成るコイル９ａが形成される。 Then, as shown in FIG. 10, the wire rod 11 is newly wound around the winding jig 12 adjacent to the previously wound wire rod 11, and by continuing this winding work, the wire rod 11 is wound. The wire rod 11 diagonally supplied around the jig 12 is sequentially folded back by a pair of guide pieces 61, 61, and the triangular wavy wire rod 11 adjacent to each other with the guide pieces 61, 61 as vertices around the winding jig 12. A coil 9a composed of a set of is formed.

ここで、一対の案内片６１，６１により順次折り返された線材１１は、一対の案内片６１，６１の回転に対して遅角する巻治具１２とともに、巻治具１２の回転方向後方に順次移動して、一対の案内片６１，６１の先端縁から抜け出すことになる。 Here, the wire rod 11 sequentially folded back by the pair of guide pieces 61, 61 is sequentially folded backward in the rotation direction of the winding jig 12 together with the winding jig 12 that is retarded with respect to the rotation of the pair of guide pieces 61, 61. It will move and escape from the tip edges of the pair of guide pieces 61, 61.

このように巻治具１２の周囲において線材１１を三角波状に巻回する巻線装置１０であって、本発明の巻線装置１０では、図１１に示す様に、ノズル７２を矢印で示す様に揺動させながら線材１１を繰り出すので、案内片６１，６１に掛け回された線材１１は、実線矢印で示す巻治具１２の回転方向後方に繰り出された後に他の案内片６１，６１側に導かれ、他の案内片６１，６１側にノズル７２が達した段階で、その線材１１は初めて折り返されることに成る。 In this way, the winding device 10 that winds the wire rod 11 in a triangular wave shape around the winding jig 12, and in the winding device 10 of the present invention, the nozzle 72 is indicated by an arrow as shown in FIG. Since the wire rod 11 is unwound while swinging to, the wire rod 11 hung around the guide pieces 61, 61 is unwound to the rear in the rotation direction of the winding jig 12 indicated by the solid arrow, and then the other guide pieces 61, 61 side. When the nozzle 72 reaches the other guide pieces 61 and 61 side, the wire rod 11 is folded back for the first time.

即ち、図１１（ａ）に示す様に、一方の案内片６１の外側にノズル７２があると、そのノズル７１から繰り出される線材１１は、先に巻回された線材１１に隣接することになる。その状態から巻治具１２と一対の案内片６１，６１を回転させつつノズル７２を揺動させると、図１１（ｂ）に示す様に、そのノズル７２からくり出された線材１１は先に巻回された線材１１を超えて巻治具１２の回転方向後方に案内される。 That is, as shown in FIG. 11A, if the nozzle 72 is located outside one of the guide pieces 61, the wire rod 11 unwound from the nozzle 71 will be adjacent to the previously wound wire rod 11. .. When the nozzle 72 is swung while rotating the winding jig 12 and the pair of guide pieces 61, 61 from that state, as shown in FIG. 11B, the wire rod 11 unwound from the nozzle 72 is wound first. It is guided backward in the rotation direction of the winding jig 12 beyond the rotated wire rod 11.

そして、図１１（ｃ）に示す様に、他の案内片６１側にノズル７２が達すると、その段階で、先に巻回された線材１１の手前に戻ってその先に巻回された線材１１に隣接しつつ巻治具１２の周囲に至る。このように、他の案内片６１側にノズル７２が達した段階で、その線材１１は一方の案内片６１において折り返され、その一方の案内片６１を頂点とする三角波状の線材１１となる。 Then, as shown in FIG. 11C, when the nozzle 72 reaches the other guide piece 61 side, at that stage, the wire rod returns to the front of the previously wound wire rod 11 and is wound ahead of the previously wound wire rod 11. It reaches the periphery of the winding jig 12 while being adjacent to 11. As described above, when the nozzle 72 reaches the other guide piece 61 side, the wire rod 11 is folded back at one guide piece 61 to become a triangular wavy wire rod 11 having the one guide piece 61 as an apex.

このように、一方の案内片６１に掛け回された線材１１を巻治具１２の回転方向後方に一旦導いた後に他方の案内片６１側に導いて線材１１を折り返すと、その折り返される線材１１の膨らみは巻治具１２の回転方向に向かう。このため、ノズルを往復移動させて、案内片において線材を直ちに折り返す従来に比較して、折り返される線材１１の巻治具１２の半径方向に外側への膨らみを少なくすることができる。よって、本発明では、両端における外径の拡大が抑制されたコイルを得ることが可能となる。 In this way, when the wire rod 11 hung around one guide piece 61 is once guided backward in the rotation direction of the winding jig 12 and then guided to the other guide piece 61 side to fold back the wire rod 11, the wire rod 11 to be folded back is formed. The bulge of the winding jig 12 goes in the rotation direction. Therefore, it is possible to reduce the bulge outward in the radial direction of the winding jig 12 of the wire rod 11 to be folded back, as compared with the conventional case in which the nozzle is reciprocated and the wire rod is immediately folded back at the guide piece. Therefore, in the present invention, it is possible to obtain a coil in which expansion of the outer diameter at both ends is suppressed.

また、案内片６１，６１が１回転する毎に巻治具１２を線材１１の太さ分だけ遅角させると、先に形成された三角波状の線材１１に隣接して新たな三角波状の線材１１が巻治具１２に巻回される。ここで、図１１に示す様に、ノズル７２を揺動させながら線材１１を繰り出す本発明では、ノズル７２から新たに繰り出される線材１１は、案内片６１，６１に掛け回された後に、先に巻回された線材１１を超えて巻治具１２の回転方向後方に案内され、その後に他の案内片６１，６１側にノズル７２が達した段階で、先に巻回された線材１１の手前に戻ってその先に巻回された線材１１に隣接しつつ巻治具１２の周囲に至る。 Further, when the winding jig 12 is retarded by the thickness of the wire rod 11 each time the guide pieces 61 and 61 make one rotation, a new triangular wavy wire rod adjacent to the previously formed triangular wavy wire rod 11 is formed. 11 is wound around the winding jig 12. Here, as shown in FIG. 11, in the present invention in which the wire rod 11 is fed while swinging the nozzle 72, the wire rod 11 newly fed out from the nozzle 72 is hung on the guide pieces 61 and 61, and then first. At the stage where the winding jig 12 is guided backward in the rotation direction beyond the wound wire 11 and then the nozzle 72 reaches the other guide pieces 61, 61 side, the front of the previously wound wire 11 It returns to the vicinity of the winding jig 12 while being adjacent to the wire rod 11 wound ahead of the wire rod 11.

このため、後に形成される三角波状の線材１１と、先の形成された三角波状の線材１１との間に隙間を生じさせるようなことはない。よって、本発明は、巻治具１２に巻回される線材１１を隣接する線材１１に密着させる、いわゆる整列巻が容易となる。 Therefore, a gap is not formed between the triangular wavy wire 11 formed later and the triangular wavy wire 11 formed earlier. Therefore, the present invention facilitates so-called aligned winding in which the wire rod 11 wound around the winding jig 12 is brought into close contact with the adjacent wire rod 11.

更に、ノズル７２が設けられた回転体７１は、その慣性モーメントを低減させることが可能なものである。従って、ノズル周囲の部材の質量が増加して、巻治具の軸方向にノズルを直線的に往復させる従来の装置に比較して、本発明のノズル７２の揺動は素早く行うことが可能となる。してみると、本発明では、巻線に係る時間を短縮させ得るものとなる。 Further, the rotating body 71 provided with the nozzle 72 can reduce the moment of inertia thereof. Therefore, the mass of the member around the nozzle increases, and the nozzle 72 of the present invention can be swung more quickly than the conventional device in which the nozzle linearly reciprocates in the axial direction of the winding jig. Become. As a result, in the present invention, the time required for winding can be shortened.

そして、巻治具１２の周囲において互いに隣接する三角波状の線材１１を密着させつつ巻線する際に、基台１０ａ上に取付けられた熱風発生器９１（図１）は、巻治具１２に臨む熱風吹き出し口９１ａから熱風を巻治具１２に向かって吹き出し、巻治具１２に隣接して巻回された線材１１を互いに接着し、その後に型が崩れることを防止する。 Then, when winding the triangular wave-shaped wire rods 11 adjacent to each other around the winding jig 12 while keeping them in close contact with each other, the hot air generator 91 (FIG. 1) mounted on the base 10a is attached to the winding jig 12. Hot air is blown toward the winding jig 12 from the hot air outlet 91a facing the winding jig 12, and the wire rods 11 wound adjacent to the winding jig 12 are adhered to each other to prevent the shape from being lost thereafter.

上記巻線作業を繰り返して単一のコイル９ａを得た後には、図１２に示す様に、その巻終わりの線材１１を支持ロッド１４に設けられた絡げピン６０に絡げることになる。 After the winding operation is repeated to obtain a single coil 9a, as shown in FIG. 12, the wire rod 11 at the end of winding is entwined with the entanglement pin 60 provided on the support rod 14. ..

この巻終わりの線材１１の絡げにあっては、ノズル移動手段８０によりそのノズル７２を支持ロッド１４に設けられた絡げピン６０の周囲に周回させ、ノズル７２から繰り出される線材１１を巻終わりの線材１１としてその絡げピン６０に絡げる。 In the entanglement of the wire rod 11 at the end of winding, the nozzle 72 is circulated around the entanglement pin 60 provided on the support rod 14 by the nozzle moving means 80, and the wire rod 11 unwound from the nozzle 72 is wound at the end of winding. It is entwined with the entwining pin 60 as a wire rod 11.

この時、支持ロッド１４には軸方向に並んで絡げピン６０が二列設けられているので、二列に設けられた絡げピン６０の、巻治具１２近傍の絡げピン６０に線材１１を掛け回した後に、巻治具１２から離れた側の絡げピン６０に線材１１を絡げるものとする。 At this time, since the support rod 14 is provided with two rows of entanglement pins 60 arranged in the axial direction, a wire rod is provided on the entanglement pins 60 near the winding jig 12 of the entanglement pins 60 provided in the two rows. After the 11 is hung around, the wire rod 11 is entwined with the entanglement pin 60 on the side away from the winding jig 12.

その後に、ノズル移動手段８０によりそのノズル７２を図２に示す仮止め具９２における係止ピン９４の周囲に周回させ、ノズル７２から繰り出される線材１１を仮止め具９２における係止ピン９４に絡げる。そして、その後に、仮止め具９２における流体圧シリンダ９３の出没ロッド９３ａを本体部９３ｂに没入させて線材１１が絡げられた係止ピン９４を移動させ、それにより、その係止ピン９４から延びる線材１１を絡げピン６０の近傍において引き千切る。 After that, the nozzle moving means 80 circulates the nozzle 72 around the locking pin 94 in the temporary fixing tool 92 shown in FIG. 2, and the wire rod 11 unwound from the nozzle 72 is entangled with the locking pin 94 in the temporary fixing tool 92. Nozzle. Then, after that, the infestation rod 93a of the fluid pressure cylinder 93 in the temporary fixing tool 92 is immersed in the main body portion 93b to move the locking pin 94 in which the wire rod 11 is entwined, thereby moving the locking pin 94 from the locking pin 94. The extending wire 11 is entwined and torn off in the vicinity of the pin 60.

その後、一対の案内片６１，６１を巻治具１２の回転方向前方に回転させて、その巻治具１２に巻回された線材１１から一対の案内片６１，６１を抜き出し、その一対の案内片６１，６１を頂点とする三角波となるように巻線された線材１１を巻治具１２の周囲に残存させて、単一のコイル９ａの作成を終了させる。 After that, the pair of guide pieces 61, 61 are rotated forward in the rotation direction of the winding jig 12, the pair of guide pieces 61, 61 are extracted from the wire rod 11 wound around the winding jig 12, and the pair of guide pieces 61, 61 are extracted. The wire rod 11 wound so as to form a triangular wave having the pieces 61 and 61 as the vertices remains around the winding jig 12, and the production of the single coil 9a is completed.

図１２に示す様に、三つのコイル９ａから成るカップ型コイル９を製造するこの実施の形態では、単一のコイル９ａを得るために行われる上記巻線作業を合計３回繰り返し、巻初めの線材１１と巻終わりの線材１１が軸方向の両側から導き出された三つのコイル９ａから成るカップ型コイル９を得る。 As shown in FIG. 12, in this embodiment in which a cup-shaped coil 9 composed of three coils 9a is manufactured, the winding operation performed to obtain a single coil 9a is repeated a total of three times to start winding. A cup-shaped coil 9 composed of three coils 9a in which the wire rod 11 and the wire rod 11 at the end of winding are derived from both sides in the axial direction is obtained.

ここで、先に単一のコイル９ａが得られている場合において、次の単一のコイル９ａを得るための巻線のスタートでは、先に得られた単一のコイル９ａから抜き出した一対の案内片６１，６１を再び回転させて図６に示すスタート位置にすることになる。 Here, in the case where the single coil 9a is obtained first, at the start of the winding for obtaining the next single coil 9a, a pair extracted from the previously obtained single coil 9a The guide pieces 61 and 61 are rotated again to reach the start position shown in FIG.

けれども、先に単一のコイル９ａが得られた状態における一対の案内片６１，６１の回転にあっては、図５に示すように、離間手段６９によって案内片６１，６１の先端を円柱状巻治具１２の外周から離間させ、その状態で行うことが好ましい。 However, in the rotation of the pair of guide pieces 61, 61 in the state where the single coil 9a is obtained first, as shown in FIG. 5, the tip of the guide pieces 61, 61 is cylindrical by the separating means 69. It is preferable to keep the winding jig 12 away from the outer circumference and perform the operation in that state.

このように、円柱状巻治具１２の外周から先端を離間させた状態で案内片６１，６１を回転させることにより、先に得られた単一のコイル９ａに回転する案内片６１，６１が接触して擦るような事態を回避することができる。 In this way, by rotating the guide pieces 61, 61 with the tip separated from the outer circumference of the columnar winding jig 12, the guide pieces 61, 61 that rotate on the single coil 9a obtained earlier can be formed. It is possible to avoid a situation where the contact and rubbing occur.

そして、上記巻線作業を合計３回繰り返し、カップ型コイル９が得られた後には、絡げピン６０に絡げられた巻初めの線材１１及び巻終わりの線材１１を解き、巻治具１２と支持具３２をそれぞれ離間させ、その間から、巻治具１２の周囲に巻回された線材１１から成るカップ型コイル９を取り外して、一連の巻線作業を終了させる。 Then, the winding operation is repeated a total of three times, and after the cup-shaped coil 9 is obtained, the wire at the beginning of winding 11 and the wire at the end of winding 11 entwined with the entwining pin 60 are unwound, and the winding jig 12 And the support 32 are separated from each other, and the cup-shaped coil 9 made of the wire rod 11 wound around the winding jig 12 is removed from between them to complete a series of winding operations.

なお、上述した実施の形態では、案内片６１の先端を巻治具１２の回転方向後方に向けて巻治具１２の外周に接触させ、一対の案内片６１，６１が１回転する毎に、巻き取る線材１１の線径分だけ巻治具１２を遅角させる場合を説明した。けれども、案内片６１の先端を巻治具１２の回転方向前方に向けて巻治具１２の外周に接触させ、一対の案内片６１，６１が１回転する毎に、巻き取る線材１１の線径分だけ巻治具１２を進角させるようにしても良い。 In the above-described embodiment, the tip of the guide piece 61 is brought into contact with the outer circumference of the winding jig 12 toward the rear in the rotation direction of the winding jig 12, and each time the pair of guide pieces 61, 61 makes one rotation, The case where the winding jig 12 is retarded by the wire diameter of the wire rod 11 to be wound has been described. However, the tip of the guide piece 61 is brought into contact with the outer circumference of the winding jig 12 toward the front in the rotation direction of the winding jig 12, and the wire diameter of the wire rod 11 to be wound every time the pair of guide pieces 61, 61 makes one rotation. The winding jig 12 may be advanced by the amount.

また、上述した実施の形態では、線材１１の端部が係止する係止手段が絡げピン６０である場合を説明したが、係止手段は、線材１１の端部が係止しうる限り、絡げピン６０に限らず、他の形式のものであっても良い。 Further, in the above-described embodiment, the case where the locking means for locking the end portion of the wire rod 11 is the entanglement pin 60 has been described, but the locking means is as long as the end portion of the wire rod 11 can be locked. , The entanglement pin 60 is not limited to that of other types.

更に、上述した実施の形態では、図６〜図１０において、巻治具１２の中心軸Ｃに直交する直交軸Ｄを中心に回転する回転体７１によりノズル７２を揺動させる場合を説明した。けれども、図示しないが、その直交軸Ｄに平行な平行軸を中心に回転体７１を回転させて、その平行軸を中心にノズル７２を揺動させるようにしても良い。 Further, in the above-described embodiment, in FIGS. 6 to 10, the case where the nozzle 72 is swung by the rotating body 71 rotating about the orthogonal axis D orthogonal to the central axis C of the winding jig 12 has been described. However, although not shown, the rotating body 71 may be rotated around a parallel axis parallel to the orthogonal axis D, and the nozzle 72 may be swung around the parallel axis.
