Description

本発明は、芯材である被巻線部材に線材を巻回して、例えば、時計コイルのような有芯コイルを得る有芯コイルの製造方法に関するものである。 The present invention relates to a manufacturing method of a cored coil in which a wire is wound around a wound member which is a core material to obtain a cored coil such as a watch coil, for example.

従来、芯材となる棒状の被巻線部材に線材を巻回する巻線方法として、対向して配置された二つの巻治具を備え、所要の巻幅と同じになるように二つの巻治具の間隔が増減され、その増減がされたところで、被巻線部材の、二つの巻治具に挟まれている部分に線材を巻回する有芯コイルの巻線方法が知られている（例えば、特許文献１参照。）。この巻線方法では、被巻線部材の、二つの巻治具に挟まれている部分に線材を巻回することにより、例え、その被巻線部材に巻幅を制限する鍔のようなものが無くても、その被巻線部材の所望の位置に所望の巻幅で線材を確実に巻回し得るとしている。 Conventionally, as a winding method for winding a wire around a rod-shaped wound member as a core material, two winding jigs arranged opposite to each other are provided, and two windings are made so as to have the same winding width. A method of winding a cored coil in which a wire is wound around a portion of a member to be wound sandwiched between two winding jigs when the interval between the jigs is increased or decreased is known. (For example, refer to Patent Document 1). In this winding method, a wire rod is wound around a portion of a member to be wound, which is sandwiched between two winding jigs, so that the winding width is limited to the member to be wound. Even if there is no wire, the wire can be reliably wound around the desired position of the wound member with a desired winding width.

特開２００８−１９２７７８号公報（図１０，段落番号００５８）JP 2008-192778 A (FIG. 10, paragraph number 0058)

しかし、上記従来の巻線方法では、被巻線部材の両端を２つの巻治具により挟んだ状態で、それら２つの巻治具を被巻線部材と共に同方向に回転させ、それにより被巻線部材の二つの巻治具に挟まれている部分に線材を巻回するので、その回転速度を高めるには限界があった。 However, in the above-described conventional winding method, the two winding jigs are rotated in the same direction together with the winding member in a state where both ends of the winding member are sandwiched between the two winding jigs. Since the wire is wound around the portion sandwiched between the two winding jigs of the wire member, there is a limit to increasing the rotation speed.

即ち、回転する巻治具にあっては、通常その回転速度が上昇すると芯ぶれを生じさせる。このため、被巻線部材の両端を２つの巻治具により挟んだ状態でそれらを同一の方向の同一の速度で回転させたとしても、その回転速度が高まると２つの巻治具の間に生じる異なる芯ぶれにより、それらの巻治具に両端が支持された被巻線部材にストレスが与えられ、その被巻線部材が、比較的割れやすい例えばフェライトのようなものであればその被巻線部材は破損してしまうような不具合があった。 In other words, a rotating winding jig usually causes runout when its rotational speed increases. For this reason, even if both ends of the member to be wound are sandwiched between two winding jigs and rotated at the same speed in the same direction, if the rotational speed increases, Due to the different core runout, stress is applied to the wound member whose both ends are supported by those winding jigs, and if the wound member is relatively easy to break, for example, ferrite, the wound member There was a problem that the wire member was damaged.

一方、被巻線部材を高速で回転させるために、その被巻線部材の一方の端部を巻治具に支持して回転させることも考えられる。しかし、被巻線部材の一方の端部を巻治具に支持して回転させると、被巻線部材が棒状であってその被巻線部材に巻幅を制限する鍔のようなものが無い様なものであれば、その被巻線部材の他方の巻幅を制限するべきものが存在しないので、その被巻線部材の所望の位置に所望の巻幅で線材を巻回することができない不具合を生じさせる。 On the other hand, in order to rotate the member to be wound at a high speed, it is also conceivable that one end of the member to be wound is supported by a winding jig and rotated. However, if one end of the member to be wound is supported by a winding jig and rotated, the member to be wound is rod-shaped and the member to be wound does not have a ridge that limits the winding width. If there is such a thing, there is no thing that should limit the other winding width of the wound member, so that the wire cannot be wound at a desired position of the wound member with a desired winding width. Cause a defect.

本発明の目的は、被巻線部材の所望の位置に所望の巻幅で線材を確実に巻回するとともに、その巻線速度を十分に高めることができる有芯コイルの製造方法を提供することにある。 An object of the present invention is to provide a method for manufacturing a cored coil capable of reliably winding a wire with a desired winding width at a desired position of a member to be wound and sufficiently increasing the winding speed. It is in.

本発明の有芯コイルの製造方法は、被巻線部材の一端を支持した第一巻治具を被巻線部材と共に回転させて被巻線部材の一端側に線材を巻回して被巻線部材の一端側に土手巻線を形成する第一巻線工程と、被巻線部材の他端を第二巻治具に支持させるとともに第一巻治具による被巻線部材の一端の支持を解消する支持軸変更工程と、被巻線部材の他端を支持した第二巻治具を被巻線部材と共に回転させて第二巻治具と土手巻線の間の被巻線部材に線材を巻回する第二巻線工程とを含む。 In the method for manufacturing a cored coil according to the present invention, a first winding jig supporting one end of a member to be wound is rotated together with the member to be wound, and a wire is wound around one end of the member to be wound. A first winding step of forming a bank winding on one end of the member, and the other end of the member to be wound is supported by the second winding jig and the one end of the member to be wound by the first winding jig is supported. The supporting shaft changing process to be eliminated, and the second winding jig supporting the other end of the wound member is rotated together with the wound member to wire the wound member between the second winding jig and the bank winding. A second winding step of winding the wire.

ここで、第一巻線工程における被巻線部材の回転速度に対して、第二巻線工程における被巻線部材の回転速度を速くすることが好ましい。 Here, it is preferable to increase the rotational speed of the member to be wound in the second winding step relative to the rotational speed of the member to be wound in the first winding step.

本発明における有芯コイルの製造方法では、被巻線部材の一端を支持した第一巻治具を回転させて、その被巻線部材の一端側に土手巻線を形成するので、この土手巻線の形成時にその被巻線部材の両端を支持するようなことはない。このため、第一巻治具の回転速度を高めて、その土手巻線を比較的素早く形成することができる。そして、この土手巻線は、被巻線部材の一端側に形成されるけれども、被巻線部材の第一巻治具が把持する部分には巻線されない。このため、その第一巻治具により、被巻線部材の一端側における巻幅を制限することができる。 In the cored coil manufacturing method of the present invention, the first winding jig supporting one end of the member to be wound is rotated to form a bank winding on one end side of the member to be wound. There is no support for both ends of the wound member when forming the wire. For this reason, the rotational speed of the first winding jig can be increased, and the bank winding can be formed relatively quickly. And although this bank winding is formed in the one end side of a to-be-wound member, it is not wound by the part which the 1st winding jig of a to-be-wound member grips. For this reason, the winding width in the one end side of a to-be-winded member can be restrict | limited by the 1st winding jig.

また、その土手巻線が形成された後には、被巻線部材の他端を第二巻治具に支持させるとともに第一巻治具による被巻線部材の一端の支持を解消し、被巻線部材の他端を支持した第二巻治具を回転させて、第二巻治具と土手巻線の間の被巻線部材に線材を巻回するので、この第二巻治具の回転による巻線時にその被巻線部材の両端を支持するようなことはない。このため、この第二巻治具の回転速度を高めて、その巻線を比較的高速に行うことができる。そして、この巻線は、第二巻治具と土手巻線の間で行われ、被巻線部材の土手巻線を越えた一端側と、他端側における第二巻治具が把持する部分には巻線されない。このため、実質的に、第一巻治具と第二巻治具が把持した被巻線部材の間に巻線が成されることになり、この被巻線部材に巻幅を制限する鍔のようなものが無い様なものであっても、この被巻線部材の所望の位置の所望の巻幅を越える端部を第一及び第二巻治具に支持させることにより、その被巻線部材の所望の位置に所望の巻幅で線材を巻回することができる。 In addition, after the bank winding is formed, the other end of the member to be wound is supported by the second winding jig, and the support of the one end of the member to be wound by the first winding jig is canceled. The second winding jig that supports the other end of the wire member is rotated to wind the wire around the member to be wound between the second winding jig and the bank winding. There is no such thing as supporting both ends of the member to be wound during winding. For this reason, the rotation speed of the second winding jig can be increased and the winding can be performed at a relatively high speed. And this winding is performed between the second winding jig and the bank winding, one end side beyond the bank winding of the member to be wound, and the part held by the second winding jig on the other end side Is not wound. For this reason, a winding is substantially formed between the wound member held by the first winding jig and the second winding jig, and the winding width is limited to the wound member. Even if there is no such thing, the end of the member to be wound exceeding the desired winding width at the desired position is supported by the first and second winding jigs to The wire can be wound at a desired position of the wire member with a desired winding width.

ここで、被巻線部材への巻線は、土手巻線と第二巻治具との間の巻線において、その大部分が行われることになる。このため、土手巻線を形成する第一巻線工程における被巻線部材の回転速度に対して、第二巻線工程における被巻線部材の回転速度を速くすることにより、被巻線部材への巻線速度を更に高めることができる。特に、被巻線部材への巻線の大部分を行う第二巻治具を基台に直接設ければ、その被巻線部材とともに回転する第二巻治具の固有振動数は高まる。このため、被巻線部材とともに第二巻治具を回転させ得る回転速度は更に高まり、この第二巻治具を回転させて巻線する巻線速度をより一層高めることができる。 Here, most of the winding to the member to be wound is performed in the winding between the bank winding and the second winding jig. For this reason, by increasing the rotation speed of the member to be wound in the second winding process relative to the rotation speed of the member to be wound in the first winding process for forming the bank winding, The winding speed can be further increased. In particular, if the second winding jig that performs most of the winding of the member to be wound is provided directly on the base, the natural frequency of the second winding jig that rotates with the member to be wound increases. For this reason, the rotational speed at which the second winding jig can be rotated together with the member to be wound is further increased, and the winding speed at which the second winding jig is rotated for winding can be further increased.

The base 11 is a relatively robust one that is unlikely to vibrate when installed at the installation location. In addition, the member to be wound 12 is a rod-like member that does not have a flange or a flange that restricts the winding width, and in this embodiment, the section is square and is wound around this. A terminal (not shown) to which end portions of the wire 46 (FIG. 2) are joined is formed on one end side. However, the member to be wound 12 is not limited to this.

It is configured to be movable.

一方、基台１１には、第一巻治具１３に対向して第二巻治具４１が設けられる。第二巻治具４１は被巻線部材１２の他端を支持するものであって、この実施の形態における第二巻治具４１は、第二モータ４２の第二回転軸４２ａに同軸に取付けられ、この第二モータ４２を介して基台１１に直接設けられる。その第二モータ４２を基台１１に固定する取付部材４３は、基台１１にボルト４３ａにより強固に固定される台板４３ｂと、その台板４３ｂに溶接されてＺ軸方向に伸びる比較的厚肉の壁板４３ｃとを備え、この壁板４３ｃに第二モータ４２がその第二回転軸４２ａをＸ軸方向に延ばして取付けられる。 On the other hand, the base 11 is provided with a second winding jig 41 facing the first winding jig 13. The second winding jig 41 supports the other end of the member to be wound 12, and the second winding jig 41 in this embodiment is attached coaxially to the second rotating shaft 42 a of the second motor 42. And provided directly on the base 11 via the second motor 42. The mounting member 43 that fixes the second motor 42 to the base 11 includes a base plate 43b that is firmly fixed to the base 11 by bolts 43a, and a relatively thick member that is welded to the base plate 43b and extends in the Z-axis direction.

The swing piece 41c and the main gripping portion 41b are formed so that the outer shape of the cross section is circular as a whole. The swing piece 41b that overlaps with the main gripping portion 41b is pivotally supported by the main gripping portion 41b by a pin 41d, and the swing piece 41c on the tip side of the pin 41d together with the main gripping portion 41b and the other of the wound member 12 By gripping the end, the second winding jig 41 is configured to support the other end of the member to be wound 12.

After the terminal and the wire 46a are electrically joined in this manner, the retracting rod 64a of the support air cylinder 64 is retracted and the electrode 65 is raised by a lifting device (not shown) so that the subsequent winding is not hindered. . After the winding start end 46a of the wire 46 is joined to a terminal (not shown), the gripping device 61 (FIG. 2) is moved away from the member to be wound 12 together with the moving plate 22, and between the gripping device 61 and the terminal.

And the holding | grip apparatus 61 in this embodiment shall convey the cut | disconnected remaining wire 46 to the wire storage box which is not shown in figure.

次に、図５に示すように、線材４６における巻初めの端部４６ａが端子に接合された被巻線部材１２の一端を第一巻治具１３に支持させる。この実施の形態では、巻初端部の線材４６ａが端子６５に抵抗溶接された被巻線部材１２の端部を第一巻治具１３に支持させる。この被巻線部材１２を第一巻治具１３に支持させるには、先ず、図４の実線矢印で示すように、操作機構２５（図２）により操作ロッド２６を前進させ、それにより先端部材２６ａを一対の把持片１８ａ，１８ｂの間に進入させて、その一対の把持片１８ａ，１８ｂを押し広げる。そして、巻治具移動機構３１（図１）により移動板２２とともに第一巻治具１３を移動させて、第二巻治具４１に他端が把持されている被巻線部材１２の一端を、その一対の把持片１８ａ，１８ｂの間に挿入する。その後、図５の破線矢印で示すように、操作ロッド２６を先端部材２６ａとともに後退させる。そして、一対のコイルスプリング１８ｅ，１８ｆ（図３）の付勢力により一対の把持片１８ａ，１８ｂを互いに接近させ、それによりその一対の把持片１８ａ，１８ｂの間に進入した被巻線部材１２の一端をその一対の把持片１８ａ，１８ｂにより挟持させる。これにより、この被巻線部材１２を第一巻治具１３に支持させる。その後、第二巻治具４１による被巻線部材１２の他端における支持を解消する。この第二巻治具４１による解消手順は後の支持軸変更工程における動作と同一であるので、ここにおける説明は省略する。 Next, as shown in FIG. 5, the first winding jig 13 supports one end of the winding member 12 in which the winding start end 46 a of the wire 46 is joined to the terminal. In this embodiment, the first winding jig 13 supports the end of the wound member 12 in which the wire 46a at the winding initial end is resistance-welded to the terminal 65. In order to support the wound member 12 on the first winding jig 13, first, the operation rod 26 is advanced by the operation mechanism 25 (FIG. 2) as shown by the solid line arrow in FIG. 26a is moved between the pair of gripping pieces 18a and 18b, and the pair of gripping pieces 18a and 18b is spread. Then, the first winding jig 13 is moved together with the moving plate 22 by the winding jig moving mechanism 31 (FIG. 1), and one end of the member to be wound 12 held at the other end by the second winding jig 41 is moved. , And inserted between the pair of gripping pieces 18a and 18b. Thereafter, as indicated by a broken line arrow in FIG. 5, the operating rod 26 is moved backward together with the tip member 26a. Then, the pair of gripping pieces 18a and 18b are brought close to each other by the urging force of the pair of coil springs 18e and 18f (FIG. 3), whereby the wound member 12 that has entered between the pair of gripping pieces 18a and 18b. One end is clamped by the pair of gripping pieces 18a and 18b. As a result, the wound member 12 is supported by the first winding jig 13. Thereafter, the support at the other end of the member to be wound 12 by the second winding jig 41 is canceled. Since the elimination procedure by the second winding jig 41 is the same as the operation in the subsequent support shaft changing step, description thereof is omitted here.

第二巻治具４１による被巻線部材１２の他端における支持を解消した後、次に、図５の実線矢印で示すように、第一巻治具１３を被巻線部材１２と共に回転させる。この回転は図２に示す第一モータ１４により行われ、第一モータ１４が駆動してその第一回転軸１４ａが第二プーリ１４ｂとともに回転すると、その回転はベルト１５により第一プーリ２４に伝達される。これにより、その第一プーリ２４が設けられた第一巻治具１３を被巻線部材１２と共に回転させる。第一巻治具１３を回転させて、線材４６を被巻線部材１２に巻回させるとき、ノズル５１を被巻線部材１２の一端側において往復移動させる。この移動はノズル移動機構５２（図２）により行われ、図５に示すように、そのノズル５１から繰出される線材４６を被巻線部材１２の一端側に集中して巻回することにより、被巻線部材１２の一端側に巻回された線材４６から成る土手巻線６２ａを形成する。 After the support at the other end of the member to be wound 12 by the second winding jig 41 is eliminated, the first winding jig 13 is then rotated together with the member to be wound 12 as indicated by the solid line arrow in FIG. . This rotation is performed by the first motor 14 shown in FIG. 2. When the first motor 14 is driven and the first rotation shaft 14a rotates together with the second pulley 14b, the rotation is transmitted to the first pulley 24 by the belt 15. Is done. Thus, the first winding jig 13 provided with the first pulley 24 is rotated together with the member to be wound 12. When the first winding jig 13 is rotated to wind the wire 46 around the member to be wound 12, the nozzle 51 is reciprocated on one end side of the member to be wound 12. This movement is performed by the nozzle moving mechanism 52 (FIG. 2). As shown in FIG. 5, by winding the wire 46 fed from the nozzle 51 in a concentrated manner on one end side of the member to be wound 12, A bank winding 62a made of a wire 46 wound around one end of the member to be wound 12 is formed.

土手巻線６２ａの程度は、被巻線部材１２の大きさやそこに巻回される線材４６の太さにより適宜決定され、例えば、直径が０．０１８５ｍｍの線材４６を用いるような場合には幅１．２ｍｍの間に２０層の巻線をすることにより得られる土手巻線６２ａが例示される。このとき、被巻線部材１２と共に回転する第一巻治具１３の回転速度は、可能な限り早いほうが好ましく、図３に示す把持機構１８を有するこの実施の形態における第一巻治具１３にあっては、毎分４〜５千回転程度の速度が期待できる。このとき、図５に示すように、第一巻治具１３に支持される被巻線部材１２の一端は、線材４６が巻回されない部分とし、この第一巻治具１３がその被巻線部材１２の一端側における巻幅を制限するものとして機能する。そして、この土手巻線６２ａの形成時に、図示しない加熱ヒータによりその土手巻線６２ａを構成する線材を加熱してそれらを互いに融着し、得られた土手巻線６２ａがその後崩れるようなことを防止する。 The degree of the bank winding 62a is determined as appropriate depending on the size of the member to be wound 12 and the thickness of the wire 46 wound around the member. For example, when the wire 46 having a diameter of 0.0185 mm is used, the width The bank winding 62a obtained by winding 20 layers between 1.2 mm is illustrated. At this time, the rotation speed of the first winding jig 13 rotating together with the member to be wound 12 is preferably as fast as possible, and the first winding jig 13 in this embodiment having the gripping mechanism 18 shown in FIG. If so, a speed of about 4 to 5,000 revolutions per minute can be expected. At this time, as shown in FIG. 5, one end of the member to be wound 12 supported by the first winding jig 13 is a portion where the wire 46 is not wound, and the first winding jig 13 It functions as limiting the winding width on one end side of the member 12. When the bank winding 62a is formed, the wire constituting the bank winding 62a is heated by a heater (not shown) to fuse them together, and the resulting bank winding 62a collapses thereafter. To prevent.

このように、第一巻線工程では、被巻線部材１２の一端を支持した第一巻治具１３を回転させて、その被巻線部材１２の一端側に土手巻線６２ａを形成するので、この土手巻線６２ａの形成時に、従来のようにその被巻線部材１２の両端を支持するようなことはない。このため、両端を支持することに起因するストレスが被巻線部材１２加わることはなく、第一巻治具１３の回転速度を高めて、その土手巻線６２ａを比較的素早く形成することができる。そして、この土手巻線６２ａは、被巻線部材１２の一端側に形成されるけれども、被巻線部材１２の第一巻治具１３が把持する部分には巻線されないので、その第一巻治具１３により、被巻線部材１２の一端側における巻幅を制限することができる。 Thus, in the first winding step, the first winding jig 13 that supports one end of the member to be wound 12 is rotated to form the bank winding 62 a on one end side of the member to be wound 12. When the bank winding 62a is formed, both ends of the member to be wound 12 are not supported as in the prior art. For this reason, stress due to supporting both ends is not applied, and the rotational speed of the first winding jig 13 can be increased and the bank winding 62a can be formed relatively quickly. . And although this bank winding 62a is formed in the one end side of the to-be-winded member 12, it is not wound by the part which the 1st winding jig | tool 13 of the to-be-winded member 12 grips, Therefore The winding width on one end side of the member to be wound 12 can be limited by the jig 13.

次の支持軸変更工程では、被巻線部材１２の他端を第二巻治具４１に支持させるとともに第一巻治具１３による被巻線部材１２の一端の支持を解消する。被巻線部材１２の他端を第二巻治具４１に支持させるには、図５に示すように、第二巻治具４１における主把持部４１ｂのＺ軸方向上方に揺動片４１ｃが存在させ、この状態で第二操作用エアシリンダ４４のロッド４４ａを没入させ、フック部材４５によりピン４１ｄより大径部側の揺動片４１ｃを押し下げる。このようにして、スプリング４１ｅの付勢力に抗して、ピン４１ｄより大径部側の揺動片４１ｃと主把持部４１ｂとの間の間隔を縮め、揺動片４１ｃの先端と主把持部４１ｂの先端の間を拡大させる。そして、巻治具移動機構３１（図１）により移動板２２と共に第一巻治具１３を移動させて、第一巻治具１３に一端が把持されている被巻線部材１２の他端を、揺動片４１ｃの先端と主把持部４１ｂの先端の間に挿入する。その後、図６に示すように、第二操作用エアシリンダ４４のロッド４４ａを突出させ、フック部材４５を上昇させてスプリング４１ｅの付勢力により、ピン４１ｄより大径部側の揺動片４１ｃと主把持部４１ｂとの間の間隔を拡大して、揺動片４１ｃの先端と主把持部４１ｂの先端により被巻線部材１２の他端を把持させる。このようにして、被巻線部材１２の他端を第二巻治具４１に支持させる。 In the next support shaft changing step, the other end of the member to be wound 12 is supported by the second winding jig 41 and the support of one end of the member to be wound 12 by the first winding jig 13 is canceled. In order to support the other end of the member to be wound 12 on the second winding jig 41, as shown in FIG. 5, the swing piece 41 c is located above the main gripping portion 41 b of the second winding jig 41 in the Z-axis direction. In this state, the rod 44a of the second operating air cylinder 44 is immersed, and the hook member 45 pushes down the swing piece 41c on the large diameter side from the pin 41d. In this way, against the urging force of the spring 41e, the distance between the swing piece 41c on the larger diameter side than the pin 41d and the main gripping portion 41b is reduced, and the tip of the swing piece 41c and the main gripping portion are reduced. The space between the tips of 41b is enlarged. Then, the first winding jig 13 is moved together with the moving plate 22 by the winding jig moving mechanism 31 (FIG. 1), and the other end of the wound member 12 whose one end is held by the first winding jig 13 is moved. Then, it is inserted between the tip of the swing piece 41c and the tip of the main gripper 41b. Thereafter, as shown in FIG. 6, the rod 44a of the second operation air cylinder 44 is protruded, the hook member 45 is raised, and the urging force of the spring 41e causes the swing piece 41c on the larger diameter side than the pin 41d to The space between the main gripping portion 41b is enlarged, and the other end of the member to be wound 12 is gripped by the tip of the swing piece 41c and the tip of the main gripping portion 41b. In this way, the other end of the member to be wound 12 is supported by the second winding jig 41.

被巻線部材１２の他端を第二巻治具４１が支持した後には第一巻治具１３による被巻線部材１２の一端の支持を解消する。これは、操作機構２５（図２）により図６の実線矢印で示すように、操作ロッド２６を先端部材２６ａとともに前進させて、その先端部材２６ａにより一対の把持片１８ａ，１８ｂを押し広げる。これにより第一巻治具１３による被巻線部材１２の一端の支持は解消し、その後、第二巻線工程の準備として、巻治具移動機構３１（図１）により第一巻治具１３を第二巻治具４１から離間させておく。その後、図７に示すように、操作ロッド２６を先端部材２６ａとともに後退させておくこともできる。 After the second winding jig 41 supports the other end of the member to be wound 12, the support of one end of the member to be wound 12 by the first winding jig 13 is canceled. As shown by the solid line arrow in FIG. 6, the operating rod 26 is advanced together with the tip member 26 a by the operating mechanism 25 (FIG. 2), and the pair of gripping pieces 18 a and 18 b are spread by the tip member 26 a. As a result, the support of one end of the member to be wound 12 by the first winding jig 13 is canceled, and then the first winding jig 13 is prepared by the winding jig moving mechanism 31 (FIG. 1) in preparation for the second winding process. Is separated from the second winding jig 41. Thereafter, as shown in FIG. 7, the operation rod 26 can be retracted together with the tip member 26a.

第二巻線工程では、図７の実線矢印で示すように、被巻線部材１２の他端を支持した第二巻治具４１を被巻線部材１２と共に回転させて第二巻治具４１と土手巻線６２ａの間の被巻線部材１２に線材４６を巻回する。第二巻治具４１の回転は第二モータ４２を駆動することにより行われ、この第二モータ４２が駆動して第二回転軸４２ａが回転すると、その第二回転軸４２ａに直接設けられた第二巻治具４１が、そこに他端が支持された被巻線部材１２とともに回転することになる。 In the second winding step, as shown by the solid line arrow in FIG. 7, the second winding jig 41 that supports the other end of the member to be wound 12 is rotated together with the member to be wound 12, so that the second winding jig 41 is rotated. The wire 46 is wound around the member 12 to be wound between the winding 62b and the bank winding 62a. The second winding jig 41 is rotated by driving the second motor 42. When the second motor 42 is driven to rotate the second rotating shaft 42a, the second winding jig 41 is directly provided on the second rotating shaft 42a. The second winding jig 41 rotates together with the member to be wound 12 on which the other end is supported.

第二巻治具４１を回転させて、線材４６を被巻線部材１２に巻回させるとき、ノズル５１を土手巻線６２ａと第二巻治具４１との間で往復移動させる。この移動はノズル移動機構５２（図２）により行われ、そのノズル５１から繰出される線材４６を土手巻線６２ａと第二巻治具４１の間に均一に巻回する。このようにして、先に形成された土手巻線６２ａに隣接して、新たに巻回された線材４６から成る新たな巻線６２ｂを被巻線部材１２に形成する。そして、この新たな巻線６２ｂの形成時にあっても、図示しない加熱ヒータによりその新たな巻線６２ｂを構成する線材を加熱してそれらを互いに融着し、得られた新たな巻線６２ｂがその後崩れるようなことを防止する。 When the second winding jig 41 is rotated to wind the wire 46 around the member to be wound 12, the nozzle 51 is reciprocated between the bank winding 62 a and the second winding jig 41. This movement is performed by the nozzle moving mechanism 52 (FIG. 2), and the wire 46 fed from the nozzle 51 is uniformly wound between the bank winding 62 a and the second winding jig 41. In this manner, a new winding 62b made of the newly wound wire 46 is formed on the member to be wound 12 adjacent to the previously formed bank winding 62a. Even when the new winding 62b is formed, the wire constituting the new winding 62b is heated by a heater (not shown) to fuse them together. Then prevent it from collapsing.

ここで、この第二巻線工程では、被巻線部材１２の他端を支持した第二巻治具４１を回転させて、第二巻治具４１と土手巻線６２ａの間の被巻線部材１２に線材４６を巻回するので、この第二巻治具４１の回転による巻線時にその被巻線部材１２の両端を支持するようなことはない。このため、両端を支持することに起因するストレスが被巻線部材１２加わることはなく、この第二巻治具４１の回転速度を高めて、その巻線を比較的高速に行うことができる。そして、この巻線は、第二巻治具４１と土手巻線６２ａの間で行われ、被巻線部材１２の土手巻線６２ａを越えた一端側と、他端側における第二巻治具４１が把持する部分には巻線されない。このため、実質的に、第一巻治具１３と第二巻治具４１が把持した被巻線部材１２の間に巻線が成されることになり、この被巻線部材１２に巻幅を制限する鍔のようなものが無い様なものであっても、この被巻線部材１２の両端部を第一及び第二巻治具１３，４１に支持させることにより、その被巻線部材１２の所望の位置に所望の巻幅で線材４６を巻回することができる。 Here, in this second winding step, the second winding jig 41 that supports the other end of the member to be wound 12 is rotated, and the winding between the second winding jig 41 and the bank winding 62a is performed. Since the wire 46 is wound around the member 12, both ends of the member to be wound 12 are not supported at the time of winding by the rotation of the second winding jig 41. For this reason, stress due to supporting both ends is not applied to the member to be wound 12, and the rotation speed of the second winding jig 41 can be increased to perform the winding at a relatively high speed. This winding is performed between the second winding jig 41 and the bank winding 62a, and the second winding jig on one end side of the member to be wound 12 beyond the bank winding 62a and the other end side. It is not wound around the part which 41 holds. Therefore, a winding is substantially formed between the wound member 12 held by the first winding jig 13 and the second winding jig 41, and the winding width Even if there is no such thing as a flaw that restricts the winding, by supporting both ends of the wound member 12 on the first and second winding jigs 13, 41, the wound member The wire 46 can be wound at a desired winding width at 12 desired positions.

また、本発明では、第二巻治具４１を回転させる第二モータ４２を比較的堅牢な取付部材４３を介して基台１１の上面に固定した。即ち、第二巻治具４１と基台１１の間には、この第二巻治具４１を移動させるような移動機構を何ら設けることをしない。このため、第二モータ４２の第二回転軸４２ａに直接取付けられた第二巻治具４１の共振を生じさせる固有振動数は著しく高められる。よって、例えば、その第二巻治具４１に支持された被巻線部材１２のバランスが多少崩れていようとも、第二巻治具４１の回転による共振は生じ難いものとなり、共振に起因する芯ぶれの発生を抑制できる。また、この実施の形態における第二巻治具４１は、その揺動片４１ｃと主把持部４１ｂを回転中心上に重心が位置するような断面外形が円形になるように形成したので、バランスは保たれ、例えば１分間に５万回転又は６万回転以上の速さで第二巻治具４１を回転させることが可能になる。このため、この第二巻治具４１を用いた巻線速度を著しく高めることができる。 Further, in the present invention, the second motor 42 that rotates the second winding jig 41 is fixed to the upper surface of the base 11 via the relatively robust attachment member 43. That is, no moving mechanism for moving the second winding jig 41 is provided between the second winding jig 41 and the base 11. For this reason, the natural frequency causing resonance of the second winding jig 41 directly attached to the second rotating shaft 42a of the second motor 42 is remarkably increased. Therefore, for example, even if the balance of the member to be wound 12 supported by the second winding jig 41 is slightly lost, resonance due to the rotation of the second winding jig 41 is difficult to occur. The occurrence of shake can be suppressed. Further, the second winding jig 41 in this embodiment is formed such that the swinging piece 41c and the main gripping portion 41b have a circular cross-sectional outer shape such that the center of gravity is located on the center of rotation. For example, the second winding jig 41 can be rotated at a speed of 50,000 revolutions or 60,000 revolutions or more per minute. For this reason, the winding speed using the second winding jig 41 can be remarkably increased.

更に、被巻線部材１２への巻線は、土手巻線６２ａと第二巻治具４１との間の巻線において、その大部分が行われることになる。このため、土手巻線６２ａを形成する第一巻線工程における被巻線部材１２の回転速度に対して、第二巻線工程における被巻線部材１２の回転速度を速くすることにより、被巻線部材１２への巻線速度を著しく高めることが期待できる。 Further, most of the winding to the member to be wound 12 is performed in the winding between the bank winding 62 a and the second winding jig 41. For this reason, by increasing the rotation speed of the member to be wound 12 in the second winding process relative to the rotation speed of the member to be wound 12 in the first winding process for forming the bank winding 62a, It can be expected that the winding speed to the wire member 12 is remarkably increased.

そして、所望の回数線材４６を被巻線部材１２に巻回することができた後は、ノズル５１を移動させて、図８に示すように、その新たな巻線６２ｂから引き出される線材４６ｂを被巻線部材１２の一端に形成された図示しない端子に重合させ、この状態で、溶接装置６３によりその線材４６ｂをその端子に接合させる。この接合手順は、巻初め端部の線材４６ａの接合手順と同一であるので、繰り返しての説明は省略する。そして、巻終わり線材４６ｂを端子に接合した後には、ノズル５１から繰出される線材４６を把持装置６１（図２）に把持させて、その把持装置６１を移動板２２とともに被巻線部材１２から遠ざけて、把持装置６１と端子の間にある線材４６をその端子の近傍において切断する。そして、図２に示すように、ノズル５１から繰出される線材４６の端部を把持装置６１に把持させて、次の巻線に備える。 Then, after the desired number of times of the wire 46 can be wound around the member to be wound 12, the nozzle 51 is moved and the wire 46b drawn from the new winding 62b is moved as shown in FIG. Polymerization is performed on a terminal (not shown) formed at one end of the member to be wound 12, and in this state, the wire 46 b is joined to the terminal by the welding device 63. Since this joining procedure is the same as the joining procedure of the wire rod 46a at the winding start end, repeated description will be omitted. Then, after joining the winding end wire 46 b to the terminal, the gripping device 61 (FIG. 2) grips the wire 46 fed from the nozzle 51, and the gripping device 61 together with the moving plate 22 from the wound member 12. At a distance, the wire 46 between the gripping device 61 and the terminal is cut in the vicinity of the terminal. Then, as shown in FIG. 2, the gripping device 61 grips the end portion of the wire 46 fed from the nozzle 51 to prepare for the next winding.

その後、図９に示すように、第二巻治具４１による被巻線部材１２の他端における支持を解消してその第二巻治具４１から被巻線部材１２を取外す。第二巻治具４１から被巻線部材１２を取外しは、主把持部４１ｂのＺ軸方向上方に揺動片４１ｃを存在させた状態で、第二操作用エアシリンダ４４のロッド４４ａを没入させ、フック部材４５によりピン４１ｄより大径部側の揺動片４１ｃを押し下げ、スプリング４１ｅの付勢力に抗して、ピン４１ｄより大径部側の揺動片４１ｃと主把持部４１ｂとの間の間隔を縮め、揺動片４１ｃの先端と主把持部４１ｂの先端の間を拡大させることにより行われる。このようにして、第二巻治具４１から取外して、土手巻線６２ａと新たな巻線６２ｂから成るコイル６２と、その被巻線部材１２を有する有芯コイル６６を得る。そして第二巻治具４１から取外された有芯コイル６６は、図示しない第二搬送装置により巻線装置１０から排出される。 After that, as shown in FIG. 9, the support at the other end of the member to be wound 12 by the second winding jig 41 is canceled and the member to be wound 12 is removed from the second winding jig 41. When the member to be wound 12 is removed from the second winding jig 41, the rod 44a of the second operating air cylinder 44 is immersed while the swing piece 41c is present above the main gripping portion 41b in the Z-axis direction. The swing member 41c on the larger diameter side than the pin 41d is pushed down by the hook member 45, and between the swing piece 41c on the larger diameter side than the pin 41d and the main gripping portion 41b against the urging force of the spring 41e. Is performed by enlarging the space between the tip of the swing piece 41c and the tip of the main gripper 41b. In this manner, the second winding jig 41 is removed to obtain the coil 62 including the bank winding 62 a and the new winding 62 b, and the cored coil 66 having the wound member 12. And the cored coil 66 removed from the 2nd winding jig 41 is discharged | emitted from the winding apparatus 10 by the 2nd conveying apparatus which is not shown in figure.

なお、上述した実施の形態では、巻幅を制限するフランジや鍔のようなものを有しない棒状の被巻線部材１２を用いて説明したが、第一及び第二巻治具１３，４１により端部が支持可能である限り、被巻線部材１２は、例えば、図１０に示すように、棒状の巻胴部１２ａの両端部にその巻胴部１２ａよりも大きな取付部１２ｂ，１２ｃが形成されたものであって、いわゆる時計コイルに用いられるようなものであっても良い。この巻胴部１２ａには絶縁紙１２ｆ（図１１）が巻回されており、図１０における符号１２ｄ，１２ｅは、一方の取付部１２ｂに形成されて、線材４６（図２）の巻初めと巻き終わりの端部が接合される端子１２ｄ，１２ｅを示す。このような被巻線部材１２に巻線を施す巻線装置１０にあっては、その第一巻治具１３における一対の把持片１８ａ，１８ｂ、及びその第二巻治具４１における揺動片４１ｃと主把持部４１ｂが、その取付部１２ｂ，１２ｃへの接触を回避して巻胴部１２ａの端部を支持するものであることが、取付部１２ｂ，１２ｃの形状がどの様なものであっても巻線が可能になるので、好ましい。 In the above-described embodiment, the description has been given using the rod-shaped wound member 12 that does not have a flange or a flange that restricts the winding width. However, the first and second winding jigs 13 and 41 are used. As long as the end portion can be supported, the wound member 12 has, as shown in FIG. 10, for example, attachment portions 12b and 12c larger than the winding drum portion 12a formed at both ends of the rod-shaped winding drum portion 12a. And may be used for a so-called watch coil. An insulating paper 12f (FIG. 11) is wound around the winding body 12a. Reference numerals 12d and 12e in FIG. 10 are formed on one of the attachment portions 12b to start winding the wire 46 (FIG. 2). The terminals 12d and 12e to which the winding end ends are joined are shown. In the winding device 10 that winds the member to be wound 12 as described above, the pair of gripping pieces 18 a and 18 b in the first winding jig 13 and the swing piece in the second winding jig 41. What is the shape of the mounting portions 12b and 12c, that the 41c and the main gripping portion 41b support the end portion of the winding drum portion 12a while avoiding contact with the mounting portions 12b and 12c. Even if it exists, since a coil | winding is attained, it is preferable.

The gripping pieces 18a and 18b shown in FIG. 11 bulge in parallel to the member to be wound 12 from both sides in the thickness direction of the member to be wound 12 of the pair of movable bases 18c and 18d, and then the member 12 to be wound. Clamping portions 18g and 18h are formed at the front end of the winding member 12 that are curved to the side and that face the winding member 12 so as to hold the end of the winding body 12a of the winding member 12 from both sides. The sandwiching portions 18g and 18h are formed with a slight thickness in the longitudinal direction of the member to be wound 12 so that the sandwiching portions 18g and 18h sandwich the end portion of the winding body portion 12a and support the end portion. Configured. As described above, when the pair of gripping pieces 18a and 18b are curved, the pair of curved gripping pieces 18a and 18b are not in contact with the mounting portion 12b provided continuously at the end of the winding drum portion 12a. , You can avoid contact there.

また、上述した実施の形態では、Ｘ軸、Ｙ軸、及びＺ軸方向伸縮アクチュエータ３２〜３４の組み合わせにより構成された巻治具移動機構３１を用いて説明したけれども、巻治具移動機構はこの構造のものに限るものではなく、第一巻治具１３が基台１１に対して移動可能である限り、この巻治具移動機構は他の形式のものであっても良い。 In the above-described embodiment, the winding jig moving mechanism 31 constituted by the combination of the X-axis, Y-axis, and Z-axis direction expansion / contraction actuators 32 to 34 has been described. The structure is not limited to the structure, and the winding jig moving mechanism may be of other types as long as the first winding jig 13 can move with respect to the base 11.

また、上述した実施の形態では、被巻線部材１２の一端を支持する一対の把持片１８ａ，１８ｂの先端面を僅かに傾斜して形成し、これにより、線材４６を被巻線部材１２の外周に案内するようにしたけれども、線材４６が第一巻治具１３自体に巻回されるような事態を回避しうる限り、被巻線部材１２の一端を支持する一対の把持片１８ａ，１８ｂの先端面を湾曲させ、これにより、線材４６を被巻線部材１２の外周に案内するようにしても良い。 In the above-described embodiment, the tip surfaces of the pair of gripping pieces 18 a and 18 b that support one end of the member to be wound 12 are formed to be slightly inclined, whereby the wire 46 is formed on the member to be wound 12. Although it is guided to the outer periphery, as long as the situation where the wire 46 is wound around the first winding jig 13 itself can be avoided, the pair of gripping pieces 18a and 18b that support one end of the member to be wound 12 are supported. It is also possible to bend the leading end surface of the wire, thereby guiding the wire 46 to the outer periphery of the member to be wound 12.

更に、上述した実施の形態では、被巻線部材１２の他端を支持する揺動片４１ｃの先端縁と主把持部４１ｂの先端縁を僅かに傾斜して形成し、これにより、揺動片４１ｃと主把持部４１ｂの先端縁に接触する線材４６を被巻線部材１２の外周に案内するようにしたけれども、線材４６が第二巻治具４１自体に巻回されるような事態を回避しうる限り、揺動片４１ｃと主把持部４１ｂの先端縁を湾曲させ、これにより、線材４６を被巻線部材１２の外周に案内するようにしても良い。 Furthermore, in the above-described embodiment, the tip edge of the swing piece 41c that supports the other end of the member to be wound 12 and the tip edge of the main gripper 41b are formed to be slightly inclined. Although the wire 46 in contact with the tip edge of 41c and the main gripper 41b is guided to the outer periphery of the member to be wound 12, the situation where the wire 46 is wound around the second winding jig 41 itself is avoided. As long as possible, the leading edges of the swinging piece 41c and the main gripping portion 41b may be curved to guide the wire 46 to the outer periphery of the member 12 to be wound.
