Description

ツイスト線製造装置、及び、ツイスト線製造方法Twist wire manufacturing apparatus and twist wire manufacturing method
　本発明は、複数の電線が撚り合わされたツイスト線を製造するための製造装置、及び、ツイスト線を製造するための製造方法に関する。 The present invention relates to a manufacturing apparatus for manufacturing a twisted wire in which a plurality of electric wires are twisted and a manufacturing method for manufacturing a twisted wire.
　従来から、電線を介して伝送される信号が外部から受ける影響（外部磁束によるノイズ）を低減すると共に、その信号が外部へ及ぼす影響（外部への磁束放出）を低減することを目的とし、各種のツイスト線が提案されている。図４（Ａ）及び図４（Ｂ）に示すように、一般に、ツイスト線Ｗｔは複数の（本例では２本の）電線Ｗ１，Ｗ２を撚り合わせることによって製造される。 Conventionally, the purpose is to reduce the influence (noise caused by external magnetic flux) that the signal transmitted through the electric wire receives from the outside, and to reduce the influence of the signal to the outside (magnetic flux release to the outside). The twist line has been proposed. As shown in FIGS. 4A and 4B, generally, the twisted wire Wt is manufactured by twisting a plurality of (in this example, two) electric wires W1 and W2.
　例えば、従来のツイスト線製造装置の一つ（以下「従来装置」という。）は、撚り合わせる前の２本の電線を略平行に並べて電線対を形成し、その電線対の一端を回転不能に固定すると共に、その他端を電線対の軸線周りに回転させることにより、ツイスト線を製造するようになっている（例えば、特許文献１～３を参照。）。 For example, one conventional twisted wire manufacturing device (hereinafter referred to as “conventional device”) forms a wire pair by arranging two wires before being twisted substantially in parallel, and makes one end of the wire pair unrotatable. A twisted wire is manufactured by fixing and rotating the other end about the axis of the electric wire pair (see, for example, Patent Documents 1 to 3).
　図３は、従来装置と同様の原理によってツイスト線を製造する装置の概略斜視図である。図３に示される装置１００は、２本の電線Ｗ１，Ｗ２（電線対）を撚り合わせてツイスト線を製造する２つの機構１０１，１０２を備えている。この装置１００は、ほぼ同じ長さの２本のツイスト線Ｗｔを同時に製造するようになっている。具体的には、機構１０１，１０２は、共用のレール１００Ａ、各電線対の一端を把持すると共に各電線対の軸線周りに回転可能な回転側チャック１００Ｂ、回転側チャック１００Ｂを回転させる共用のモータ１００Ｃ、各電線対の他端を把持すると共に回転不能に固定する固定側チャック１００Ｄ、固定側チャック１００Ｄを介して各電線対に張力を付与するテンション付与部１００Ｅ、テンション付与部１００Ｅが固定された共用の支持台１００Ｆ、及び、これらを支持する基台１００Ｇ、を備える。 FIG. 3 is a schematic perspective view of an apparatus for manufacturing a twisted wire based on the same principle as that of a conventional apparatus. The apparatus 100 shown in FIG. 3 includes two mechanisms 101 and 102 that produce twisted wires by twisting two electric wires W1 and W2 (wire pairs). This apparatus 100 is designed to simultaneously produce two twist lines Wt having substantially the same length. Specifically, the mechanisms 101 and 102 include a common rail 100A, one end of each wire pair, and a rotation side chuck 100B that can rotate around the axis of each wire pair, and a common motor that rotates the rotation side chuck 100B. 100C, fixed side chuck 100D that holds the other end of each wire pair and is fixed so as not to rotate, tension applying unit 100E that applies tension to each wire pair via the fixed side chuck 100D, and tension applying unit 100E are fixed A common support base 100F and a base 100G for supporting them are provided.
　図３の装置１００は、各電線対に張力を付与した状態にて回転側チャック１００Ｂを回転させることにより、図４（Ｃ）に示すように、電線対を形成する電線Ｗ１，Ｗ２（図中ではＡ，Ｂ）を互いの位置を入れ替えるように回転させ、電線Ｗ１，Ｗ２を撚り合わせるようになっている。具体的には、回転側チャック１００Ｂの１回転は図４（Ｃ）の（１）～（５）の工程に対応し、回転側チャック１００Ｂが２回転することによって図４（Ｂ）のツイスト線Ｗｔが形成されることになる。 3 rotates the rotation-side chuck 100B in a state where tension is applied to each wire pair, and as shown in FIG. 4C, the wires W1 and W2 forming the wire pairs (in the drawing) Then, A and B) are rotated so as to exchange their positions, and the electric wires W1 and W2 are twisted together. Specifically, one rotation of the rotation-side chuck 100B corresponds to the steps (1) to (5) in FIG. 4C, and the rotation of the rotation-side chuck 100B makes two rotations so that the twist line in FIG. Wt is formed.
　なお、図４（Ｂ）に示す長さＬｐは、電線対がその軸線周りに３６０度回転するためのツイスト線Ｗｔの長さ（換言すると、図４（Ｃ）の（１）～（５）の工程に対応する長さ）であり、ツイスト線Ｗｔの「ピッチ長」と称呼される。また、図４（Ｂ）に示す長さＬｔは、ツイスト線Ｗｔの両端の端子部分を除いた電線部分の長さであり、ツイスト線Ｗｔの「全長」（又は単に「長さ」）と称呼される。 Note that the length Lp shown in FIG. 4B is the length of the twisted wire Wt for rotating the wire pair 360 degrees around its axis (in other words, (1) to (5) in FIG. 4C). This is a length corresponding to the process (2), and is referred to as “pitch length” of the twist line Wt. Also, the length Lt shown in FIG. 4B is the length of the electric wire portion excluding the terminal portions at both ends of the twisted wire Wt, and is referred to as the “full length” (or simply “length”) of the twisted wire Wt. Is done.

　図３に示す装置１００（及び従来装置）は、電線Ｗ１，Ｗ２同士を適切に撚り合わせる観点から、常に電線対Ｗ１，Ｗ２を長さ方向に引っ張った状態（引張応力を付与した状態）を維持しながら、回転側チャック１００Ｂを回転させるようになっている。これは、電線Ｗ１，Ｗ２がたるんだ状態にて回転側チャック１００Ｂを回転させると、ツイスト線のピッチ長Ｌｐが不均一になる等の不具合が生じる可能性があるためである。 The apparatus 100 (and the conventional apparatus) shown in FIG. 3 always maintains the state in which the wire pair W1, W2 is pulled in the length direction (a state in which a tensile stress is applied) from the viewpoint of appropriately twisting the wires W1, W2. However, the rotation side chuck 100B is rotated. This is because if the rotation-side chuck 100B is rotated while the electric wires W1 and W2 are slack, there may be a problem such as the pitch length Lp of the twist wire being non-uniform.
　ところが、電線対Ｗ１，Ｗ２を長さ方向に引っ張った状態を保つためには、基台１００Ｇの長さを電線Ｗ１，Ｗ２の長さ（ひいては、最終的なツイスト線の目標長さ）以上とする必要がある。そのため、ツイスト線の目標長さが長くなるにつれて、装置１００が大型化する。また、ツイスト線の目標長さの変更に応じて固定側チャック１００Ｄの位置を変更する必要があり、ツイスト線を製造する工程が煩雑化する。 However, in order to keep the wire pair W1, W2 pulled in the length direction, the length of the base 100G is set to be equal to or longer than the length of the wires W1, W2 (and eventually the target length of the twisted wire). There is a need to. Therefore, the apparatus 100 becomes larger as the target length of the twist line becomes longer. In addition, it is necessary to change the position of the fixed chuck 100D in accordance with the change in the target length of the twist line, which complicates the process of manufacturing the twist line.
　本発明は、上記のような実情に鑑みてなされたものであり、その目的は、従来装置よりも小型化が可能であり、ツイスト線の目標長さが変更されてもツイスト線の製造工程の煩雑化を出来る限り防ぐことが可能な、ツイスト線製造装置及びツイスト線製造方法を提供することにある。 The present invention has been made in view of the above circumstances, and its purpose is that it can be made smaller than conventional devices, and even if the twisted wire target length is changed, the twisted wire manufacturing process An object of the present invention is to provide a twisted wire manufacturing apparatus and a twisted wire manufacturing method capable of preventing complication as much as possible.

(1)

A winding shaft for winding a plurality of electric wires, wherein the plurality of electric wires are wound so that the plurality of electric wires spirally rotate in the same direction on the outer circumferential surface of the winding shaft;

It is a twist wire manufacturing apparatus provided with.
(2)
In the twisted wire manufacturing apparatus according to (1) above,
The winding shaft is
Having an outer peripheral length determined based on a target pitch length of the twisted line;
It is a twisted wire manufacturing device.
(3)
The twisted wire manufacturing apparatus according to (1) or (2) above,
A rotation mechanism for rotating the winding shaft around an axis,
An electric wire feeding section that longitudinally runs along the axis of the winding shaft while feeding the plurality of electric wires before being wound on the winding shaft toward the winding shaft;
A drive mechanism for driving the wire delivery section,
It is a twisted wire manufacturing device.
(4)
A twisted wire manufacturing method for manufacturing a twisted wire in which a plurality of electric wires are twisted together,

Winding the plurality of electric wires around the winding shaft so that the plurality of electric wires circulate in the same direction on the outer peripheral surface of the winding shaft;

Stretching the plurality of electric wires;
Including a twisted wire manufacturing method.
　上記（１）の構成のツイスト線製造装置によれば、巻取軸の外周面上を螺旋状に同一の向きに周回するように複数の電線を巻き取ることにより、複数の電線が螺旋状（コイルスプリング状）に巻回した巻回体を形成できる。この巻回体は、後述する処理によってツイスト線に加工されるため、ツイスト線の前処理体とも表現できる。このように巻き取られた複数の電線（巻回体）を、巻取り向きに周回した状態を維持しながら巻取軸から抜き取った後に（又は抜き取りながら）、その長さ方向に引き伸ばすと、螺旋形状の複数の電線（巻回体）の中空部分が徐々に小さくなりながら、複数の電線の各々が互いに密着することになる。このとき、複数の電線は、互いの位置を入れ替えるように回転（偏心旋回）することになる（図２も参照。）。その結果、複数の電線がひねられながら互いに密着し、ツイスト線が形成される。ツイスト線の長さ（全長）は、巻取軸に巻き取られる複数の電線の長さに対応する。よって、ツイスト線の目標長さに応じて巻取軸に巻き取られる複数の電線の長さを増減すれば、装置を肥大化させることなく、任意の目標長さに対応できることになる。したがって、本ツイスト線製造装置は、従来装置よりも小型化が可能であり、ツイスト線の目標長さが変更されてもツイスト線の製造工程の煩雑化を出来る限り防止できる。 According to the twisted wire manufacturing apparatus having the above configuration (1), a plurality of electric wires are spirally wound by winding a plurality of electric wires so as to circulate on the outer peripheral surface of the winding shaft in the same direction spirally ( A wound body wound in a coil spring shape can be formed. Since this wound body is processed into a twisted line by a process to be described later, it can also be expressed as a twisted line pre-processed body. When a plurality of electric wires (winding bodies) wound in this way are pulled out from the winding shaft while maintaining a state in which they are wound in the winding direction (or while being pulled out), when they are stretched in the length direction, the spiral Each of the plurality of wires comes into close contact with each other while the hollow portions of the plurality of shaped wires (winding bodies) are gradually reduced. At this time, the plurality of electric wires rotate (eccentric turn) so as to exchange their positions (see also FIG. 2). As a result, the plurality of electric wires are in close contact with each other while being twisted, and a twisted wire is formed. The length (full length) of the twisted wire corresponds to the length of the plurality of electric wires wound around the winding shaft. Therefore, if the lengths of the plurality of electric wires wound on the winding shaft are increased or decreased according to the target length of the twisted wire, it is possible to cope with an arbitrary target length without enlarging the device. Therefore, this twist line manufacturing apparatus can be made smaller than the conventional apparatus, and even if the target length of the twist line is changed, the twist line manufacturing process can be prevented as much as possible.
　上記（２）の構成のツイスト線製造装置によれば、目標ピッチ長に対応した外周長さを有する巻取軸を適宜選択すれば、任意のピッチ長を有するツイスト線を製造できる。 According to the twisted wire manufacturing apparatus having the configuration (2) above, a twisted wire having an arbitrary pitch length can be manufactured by appropriately selecting a winding shaft having an outer peripheral length corresponding to the target pitch length.
　上記（３）の構成のツイスト線製造装置によれば、巻取軸の回転速度（即ち、単位時間あたりに巻取軸に巻き取られる複数の電線の長さ）を考慮しながら電線送出部を縦走させることにより、巻取軸の外周面上において複数の電線が重なる（重複するように巻き付けられる）ことを防止できる。その結果、最終的に形成されるツイスト線のピッチ長のばらつきを小さくできる。 According to the twisted wire manufacturing apparatus having the configuration of (3) above, the electric wire sending section is arranged while taking into consideration the rotation speed of the take-up shaft (that is, the length of a plurality of electric wires taken up by the take-up shaft per unit time). By longitudinally running, it is possible to prevent a plurality of electric wires from overlapping (wrapped so as to overlap) on the outer peripheral surface of the winding shaft. As a result, the variation in the pitch length of the finally formed twist line can be reduced.
　上記（４）の構成のツイスト線製造方法によれば、上記（１）と同様、製造装置を従来装置よりも小型化させることが可能であり、ツイスト線の目標長さが変更されてもツイスト線の製造工程の煩雑化を出来る限り防止できる。 According to the twisted wire manufacturing method having the configuration of (4) above, the manufacturing apparatus can be made smaller than the conventional device as in the above (1), and the twisted wire can be twisted even if the target length of the twisted wire is changed. The complication of the wire manufacturing process can be prevented as much as possible.
　本発明のツイスト線製造装置およびツイスト線製造方法によれば、従来装置よりも装置の小型化が可能であり、ツイスト線の目標長さが変更されてもツイスト線の製造工程の煩雑化を出来る限り防ぐことが可能である。 According to the twisted wire manufacturing apparatus and the twisted wire manufacturing method of the present invention, the device can be made smaller than the conventional device, and the twisted wire manufacturing process can be complicated even if the target length of the twisted wire is changed. It is possible to prevent as long as possible.

　以下、本発明の一の実施形態に係るツイスト線製造装置（以下「装置１０」という。）を、図１及び図２を参照しながら説明する。
＜主要な構成＞
　装置１０は、図１に示すように、複数の電線Ｗ１，Ｗ２を巻き取る巻取軸２０、巻取軸２０をその軸線周りに回転駆動する第１モータ２０Ｍ、巻取軸２０に複数の電線Ｗ１，Ｗ２の端部を固定する固定具２０Ｈ、巻取軸２０への複数の電線Ｗ１，Ｗ２の巻取りを補助するトラバース機構３０、巻取軸２０に巻き取られる前の複数の電線Ｗ１，Ｗ２を巻取軸２０に向けて送出しながら巻取軸２０の軸線に沿って縦走する電線送出部３１、電線送出部３１を駆動するための駆動軸３２、電線送出部３１を巻取軸２０の軸線に沿って移動させるための案内軸３３、駆動軸３２を回転駆動する第２モータ３０Ｍ、巻取軸２０及び駆動軸３２を各々の軸線周りに回転可能に支持し且つ案内軸３３を支持する支持体４０、並びに、巻取軸２０に巻き取られた複数の電線を巻取り向きに周回した状態を維持しながら巻取軸２０から抜き取るための分離機構５０、を備えている。 Hereinafter, a twisted wire manufacturing apparatus (hereinafter referred to as “apparatus 10”) according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
<Main configuration>
As shown in FIG. 1, the apparatus 10 has a winding shaft 20 for winding a plurality of electric wires W1, W2, a first motor 20M for rotating the winding shaft 20 around its axis, and a plurality of electric wires on the winding shaft 20. A fixing tool 20H for fixing the ends of W1 and W2, a traverse mechanism 30 for assisting winding of the plurality of electric wires W1 and W2 around the winding shaft 20, and a plurality of electric wires W1 before being wound around the winding shaft 20. An electric wire sending section 31 that runs vertically along the axis of the winding shaft 20 while sending W2 toward the winding shaft 20, a drive shaft 32 for driving the electric wire sending section 31, and the electric wire sending section 31 as the winding shaft 20 The guide shaft 33 for moving along the axis of the second shaft, the second motor 30M for rotationally driving the drive shaft 32, the take-up shaft 20 and the drive shaft 32 are supported so as to be rotatable around the respective axes, and the guide shaft 33 is supported. To be wound around the support body 40 and the winding shaft 20 And a 50, the separation mechanism for extracting from the winding shaft 20 while maintaining a state in which around the plurality of wires in the winding direction.
　電線Ｗ１，Ｗ２の両端末には、予め端子が設けられている。なお、端末に端子を予め設けるか否かは、装置１０による処理（ツイスト処理）の前後の工程等を考慮して適宜選択されればよく、装置１０による処理の前に必ずしも端子を設ける処理を行う必要はない。 Terminals are provided in advance at both terminals of the electric wires W1 and W2. Whether or not the terminal is provided in advance in the terminal may be appropriately selected in consideration of the process before and after the process (twist process) by the apparatus 10, and the process of providing the terminal is not necessarily performed before the process by the apparatus 10. There is no need to do it.
　以下、便宜上、複数の電線Ｗ１，Ｗ２を「電線対Ｗ１，Ｗ２」とも称呼する。但し、装置１０は３本以上の電線からツイスト線を形成することも可能であり、装置１０によって処理される電線の数は必ずしも２本（一対の電線）に制限されない。 Hereinafter, for convenience, the plurality of electric wires W1 and W2 are also referred to as “electric wire pairs W1 and W2.” However, the apparatus 10 can also form a twisted wire from three or more electric wires, and the number of electric wires processed by the apparatus 10 is not necessarily limited to two (a pair of electric wires).
＜巻取軸２０＞
　巻取軸２０は、電線対Ｗ１，Ｗ２をその外周面上に螺旋状（コイルスプリング状）に巻き付ける柱状体であって、電線対Ｗ１，Ｗ２の端部を着脱自在に固定する固定具２０Ｈを備えている。巻取軸２０は、電線対Ｗ１，Ｗ２を螺旋状に巻き付けるものであるから、円柱形状を有することが望ましいが、必ずしも円柱形状に限定されない。 <Winding shaft 20>
The winding shaft 20 is a columnar body that winds the electric wire pair W1, W2 around the outer peripheral surface in a spiral shape (coil spring shape), and includes a fixing tool 20H that detachably fixes the ends of the electric wire pair W1, W2. I have. Since the winding shaft 20 is for winding the wire pair W1 and W2 in a spiral shape, it is desirable to have a columnar shape, but it is not necessarily limited to the columnar shape.
　巻取軸２０の外周長さは、後述するように、電線Ｗ１，Ｗ２によって形成されるツイスト線のピッチ長に関係する。そのため、ツイスト線の目標ピッチ長に対応した外周長さを有する巻取軸２０を選択できるよう、支持体４０は、任意の外周長さの巻取軸２０を取り付け可能であるように構成されることが望ましい。なお、ツイスト線のピッチ長は、巻取軸２０の回転速度と、トラバース機構３０による電線送出部３１の移動速度と、を調整することによっても変更できる。 The outer peripheral length of the winding shaft 20 is related to the pitch length of the twisted wires formed by the electric wires W1 and W2, as will be described later. Therefore, the support body 40 is configured so that the winding shaft 20 having an arbitrary outer peripheral length can be attached so that the winding shaft 20 having an outer peripheral length corresponding to the target pitch length of the twist line can be selected. It is desirable. The pitch length of the twisted wire can also be changed by adjusting the rotational speed of the winding shaft 20 and the moving speed of the wire sending section 31 by the traverse mechanism 30.
　更に、巻取軸２０の長さは、ツイスト線の全長に関係する。そのため、ツイスト線の目標長さに対応した長さを有する巻取軸２０を選択できるよう、支持体４０は任意の長さの巻取軸２０を取り付け可能であるように構成されることが望ましい。 Furthermore, the length of the winding shaft 20 is related to the total length of the twisted wire. Therefore, it is desirable that the support body 40 be configured so that the winding shaft 20 having an arbitrary length can be attached so that the winding shaft 20 having a length corresponding to the target length of the twist line can be selected. .
　本例における巻取軸２０は、第１モータ２０Ｍによって回転駆動される。しかし、この第１モータ２０Ｍに代えて、手回しハンドル等の駆動機構を用いてもよい。 The winding shaft 20 in this example is rotationally driven by the first motor 20M. However, instead of the first motor 20M, a driving mechanism such as a handwheel may be used.
＜トラバース機構３０＞
　トラバース機構３０は、巻取軸２０に電線対Ｗ１，Ｗ２を互いに重なることなく並行して均一な巻取ピッチ幅にて巻き付けるべく、巻き付けられる前の電線対Ｗ１，Ｗ２を巻取軸２０に向けて送出しながら電線送出部３１を移動させるための機構である。 <Traverse mechanism 30>
The traverse mechanism 30 directs the wire pair W1, W2 before being wound around the take-up shaft 20 in order to wind the wire pairs W1, W2 around the take-up shaft 20 in parallel with a uniform take-up pitch width. This is a mechanism for moving the wire sending section 31 while sending it out.
　なお、装置１０は、必ずしもトラバース機構３０を備える必要はなく、トラバース機構３０の機能を、他の治具で行うことも可能であり、操作者の手作業にて行うことも可能である。 In addition, the apparatus 10 does not necessarily need to be provided with the traverse mechanism 30, the function of the traverse mechanism 30 can be performed by another jig, and can be performed manually by the operator.
　トラバース機構３０は、電線送出部３１と、表面に螺旋ネジ３２Ｒが設けられ且つ第２モータ３０Ｍに連動して回転する駆動軸３２と、駆動軸３２に平行に配置された案内軸３３と、から構成されている。電線送出部３１は、駆動軸３２の螺旋ネジ３２Ｒに対応するナット部３２Ｎと、案内軸３３を貫通させるための貫通穴３３Ｈと、電線対Ｗ１，Ｗ２を送出しながら保持するフォーク３１Ｆと、を備えている。ナット部３２Ｎには駆動軸３２が螺合され、貫通穴３３Ｈには案内軸３３が貫通するように設けられる。本構成により、第２モータ３０Ｍによって駆動軸３２が回転駆動されると、電線送出部３１が案内軸３３に沿って（巻取軸２０と平行に）移動することになる。 The traverse mechanism 30 includes an electric wire sending part 31, a drive shaft 32 provided with a helical screw 32R on the surface and rotating in conjunction with the second motor 30M, and a guide shaft 33 arranged in parallel to the drive shaft 32. It is configured. The electric wire delivery part 31 includes a nut part 32N corresponding to the spiral screw 32R of the drive shaft 32, a through hole 33H for allowing the guide shaft 33 to pass therethrough, and a fork 31F for holding the electric wire pair W1, W2 while feeding them. I have. The drive shaft 32 is screwed into the nut portion 32N, and the guide shaft 33 is provided to pass through the through hole 33H. With this configuration, when the drive shaft 32 is rotationally driven by the second motor 30M, the electric wire delivery section 31 moves along the guide shaft 33 (in parallel with the winding shaft 20).
＜分離機構５０＞
　装置１０は、巻取軸２０に巻き取られた電線対Ｗ１，Ｗ２を巻取り向きに周回した状態を維持しながら前記巻取軸から抜き取ることを可能とする機構（分離機構）を備える必要がある。例えば、装置１０は、巻取軸２０を第１モータ２０Ｍから容易に取り外すことができるよう、第１モータ２０Ｍのモータシャフト（出力軸）と巻取軸２０とを噛み合わせクラッチを介して結合する分離機構５０を採用している。なお、分離機構は、上述したように電線対Ｗ１，Ｗ２を巻取軸２０から抜き取ることを可能とする機構であればよく、この噛み合わせクラッチに限定されない。 <Separation mechanism 50>
The apparatus 10 needs to include a mechanism (separation mechanism) that enables the wire pair W1 and W2 wound around the winding shaft 20 to be pulled out from the winding shaft while maintaining a state in which the wire pair is wound in the winding direction. is there. For example, the apparatus 10 engages the motor shaft (output shaft) of the first motor 20M and the winding shaft 20 via a meshing clutch so that the winding shaft 20 can be easily detached from the first motor 20M. A separation mechanism 50 is employed. The separation mechanism may be any mechanism that allows the wire pair W1, W2 to be extracted from the winding shaft 20 as described above, and is not limited to this engagement clutch.
＜ツイスト線の製造方法＞
　次いで、装置１０を用いてツイスト線を製造するための工程（１）～（４）について説明する。 <Method for producing twisted wire>
Next, steps (1) to (4) for manufacturing a twisted wire using the apparatus 10 will be described.
（１）電線の取り付け
　巻き取り前の電線対Ｗ１，Ｗ２の端部を巻取軸２０の固定具２０Ｈに固定する。なお、固定具２０Ｈに代えて、粘着テープ等を用いて電線対Ｗ１，Ｗ２を固定してもよい。更に、電線対Ｗ１，Ｗ２をトラバース機構３０のフォーク３１Ｆを通過させるように、トラバース機構３０に取り付ける。 (1) Attachment of electric wire The ends of the electric wire pair W1, W2 before winding are fixed to the fixture 20H of the winding shaft 20. Note that the wire pair W1, W2 may be fixed using an adhesive tape or the like instead of the fixture 20H. Further, the electric wire pair W1, W2 is attached to the traverse mechanism 30 so as to pass the fork 31F of the traverse mechanism 30.
（２）電線の巻き付け
　第１モータ２０Ｍを作動させることによって巻取軸２０をその軸線周りに回転駆動すると共に、第２モータ３０Ｍを作動させることによって電線送出部３１を巻取軸２０に縦走させる。これにより、電線対Ｗ１，Ｗ２が巻取軸２０の外周面上を螺旋状（コイルスプリング状）に同一の向きに周回するように巻き取られる。
（３）電線の取り外し
　巻取軸２０に巻き取られた電線対Ｗ１，Ｗ２を、上記（３）における巻取り向きに周回した状態を維持しながら、巻取軸２０から抜き取る。例えば、巻取軸２０と第２モータ３０Ｍの出力軸との結合を分離機構５０によって一時的に解除し（例えば、分離機構５０の位置にて、巻取軸２０を第２モータ３０Ｍの出力軸から切り離し）、巻取軸２０の軸線方向に電線対Ｗ１，Ｗ２を引き出すことにより、電線対Ｗ１，Ｗ２を巻取軸２０から取り外すことができる。
（４）電線の引き伸ばし
　巻取軸２０から取り外された（又は取り外しながら）電線対Ｗ１，Ｗ２を長さ方向に（即ち、電線対の一端と他端とを離すように）引き伸ばすことにより、螺旋形状の電線対Ｗ１，Ｗ２（巻回体）の中空部分が徐々に小さくなりながら、電線対Ｗ１，Ｗ２の各々が互いに密着することになる。このとき、後述するように、複数の電線が偏心旋回するようにひねられることになる。その結果、ツイスト線が成形される。 (2) Winding of electric wire The first motor 20M is operated to rotate the winding shaft 20 around its axis, and the second motor 30M is operated to cause the electric wire sending section 31 to run vertically on the winding shaft 20. . As a result, the wire pair W1, W2 is wound around the outer peripheral surface of the winding shaft 20 so as to circulate in the same direction in a spiral shape (coil spring shape).
(3) Removal of electric wire The electric wire pair W1, W2 wound around the take-up shaft 20 is pulled out from the take-up shaft 20 while maintaining a state in which the wire pair W1 and W2 are wound in the winding direction in (3). For example, the coupling between the winding shaft 20 and the output shaft of the second motor 30M is temporarily released by the separation mechanism 50 (for example, the winding shaft 20 is moved to the output shaft of the second motor 30M at the position of the separation mechanism 50). The electric wire pair W1, W2 can be removed from the take-up shaft 20 by pulling out the electric wire pair W1, W2 in the axial direction of the take-up shaft 20.
(4) Stretching the wire Spiral by stretching the wire pair W1, W2 removed from (or removed from) the take-up shaft 20 in the length direction (ie, separating one end and the other end of the wire pair). Each of the wire pairs W1, W2 comes into close contact with each other while the hollow portions of the shaped wire pairs W1, W2 (winding bodies) are gradually reduced. At this time, as will be described later, the plurality of electric wires are twisted so as to be eccentrically turned. As a result, a twisted wire is formed.
＜ツイスト線が形成される原理＞
　上述した工程によってツイスト線が形成される原理について説明する。 <Principle of twisted wire formation>
The principle that the twisted line is formed by the above-described process will be described.
　図２（１）は、円柱状の巻取軸２０に電線対Ｗ１，Ｗ２が螺旋状に巻き取られた様子を示している。本図では、巻取軸２０に電線対Ｗ１，Ｗ２が並行して整列されている状態を分かり易く示すため、電線対Ｗ１，Ｗ２の各々が白と黒に色分けされている。 FIG. 2 (1) shows a state in which the wire pair W 1 and W 2 are spirally wound around the cylindrical winding shaft 20. In this figure, in order to show the state in which the wire pairs W1, W2 are aligned in parallel on the winding shaft 20, each of the wire pairs W1, W2 is color-coded in white and black.
　図２（２）は、電線対Ｗ１，Ｗ２が巻取り方向に周回した状態を維持しながら、螺旋状に巻き取られた電線対を巻取軸２０から取り外す様子（電線対の一端側と他端側を引き離す様子）を示している。このとき、電線対Ｗ１，Ｗ２がその長さ方向に徐々に引き伸ばされ、螺旋形状の電線対Ｗ１，Ｗ２（巻回体）の中空部分が徐々に小さくなりながら、電線対Ｗ１，Ｗ２の各々が互いに近付く。 2 (2) shows a state in which the wire pair wound in a spiral shape is removed from the winding shaft 20 while maintaining the state in which the wire pairs W1 and W2 are wound in the winding direction (one end side of the wire pair and others). The state where the end side is pulled apart) is shown. At this time, the electric wire pairs W1, W2 are gradually stretched in the length direction, and the hollow portions of the spiral electric wire pairs W1, W2 (winding bodies) are gradually reduced. Approach each other.
　図２（２）に示す（ａ）～（ｃ）は、電線対Ｗ１，Ｗ２（巻回体）を巻取軸２０の軸線に直交する平面にて切断した場合における巻取軸２０の断面を図中の右方向から見た場合の部分断面図である。便宜上、電線Ｗ１の断面には符号Ａが付され、電線Ｗ２の断面には符号Ｂが付されている。部分断面図（ａ）～（ｃ）に示すように、電線対Ｗ１，Ｗ２（巻回体）が引き伸ばされると、電線対Ｗ１，Ｗ２を構成する電線の各々（図中ではＡ，Ｂ）は、巻取軸２０の軸線（巻回体である電線対Ｗ１，Ｗ２の軸線）に対して偏心しながら互いの位置を入れ替えるように回転（偏心旋回）する。これにより、図４（Ｃ）に示す例と同様、電線対Ｗ１，Ｗ２がひねられる。 FIGS. 2A to 2C show cross sections of the winding shaft 20 when the wire pair W1, W2 (winding body) is cut along a plane perpendicular to the axis of the winding shaft 20. FIG. It is a fragmentary sectional view at the time of seeing from the right direction in the figure. For convenience, the cross section of the electric wire W1 is denoted by the symbol A, and the cross section of the electric wire W2 is denoted by the symbol B. As shown in the partial sectional views (a) to (c), when the wire pair W1, W2 (winding body) is stretched, each of the wires constituting the wire pair W1, W2 (A and B in the figure) is Rotating (eccentric swirl) so that the positions of the winding shaft 20 are exchanged while being eccentric with respect to the axis of the winding shaft 20 (the axis of the wire pair W1, W2 as the winding body). Thereby, the electric wire pair W1, W2 is twisted similarly to the example shown in FIG.
　図２（３）は、電線対Ｗ１，Ｗ２が更に引き伸ばされた状態を示している。このとき、電線対Ｗ１，Ｗ２は、上述したようにひねられた状態にて互いに密着する。その結果、ツイスト線が形成される。 FIG. 2 (3) shows a state in which the wire pair W1, W2 is further stretched. At this time, the wire pairs W1, W2 are in close contact with each other in the twisted state as described above. As a result, a twist line is formed.
　なお、図２（２）の部分断面図（ａ）に示す位置から部分断面図（ｃ）に示す位置までの電線対Ｗ１，Ｗ２の長さは、巻取軸２０の外周長さにほぼ一致する。この長さは、図２（３）に示すように、電線対Ｗ１，Ｗ２によって最終的なツイスト線が形成されたときのツイスト線のピッチ長Ｌｐに相当する。 Note that the lengths of the electric wire pairs W1 and W2 from the position shown in the partial cross-sectional view (a) of FIG. 2 (2) to the position shown in the partial cross-sectional view (c) are substantially equal to the outer peripheral length of the winding shaft 20. To do. As shown in FIG. 2 (3), this length corresponds to the pitch length Lp of the twist line when the final twist line is formed by the wire pairs W1, W2.
　よって、巻取軸２０の外周長さをツイスト線のピッチ長Ｌｐの目標値に基づいて設定することにより、任意のピッチ長Ｌｐを有するツイスト線を形成できる。また、ピッチ長Ｌｐは、巻取軸２０の外周を一周する距離に関係するため、電線対Ｗ１，Ｗ２が巻取軸２０を一周する間に電線送出部３１が移動する距離を大きくすると、ピッチ長Ｌｐが長くなる。そのため、巻取軸２０の回転速度と、電線送出部３１の移動速度と、を調節することにより、ピッチ長Ｌｐを変更することも可能である。 Therefore, by setting the outer peripheral length of the winding shaft 20 based on the target value of the pitch length Lp of the twisted wire, a twisted wire having an arbitrary pitch length Lp can be formed. Further, since the pitch length Lp is related to the distance that goes around the outer periphery of the winding shaft 20, if the distance that the wire sending portion 31 moves while the wire pair W1, W2 goes around the winding shaft 20 is increased, the pitch The length Lp becomes longer. Therefore, it is also possible to change the pitch length Lp by adjusting the rotation speed of the winding shaft 20 and the moving speed of the wire sending section 31.
