Description
【発明の詳細な説明】 （産業上の利用分野） この発明はトロイダルコイルの巻線方法に関する。The present invention relates to a method for winding a toroidal coil.
（従来の技術） トロイダルコイルを製作する場合、線材をリング状の
コアの孔に挿通する操作を繰り返し行うのであるが、こ
の場合、コアの孔径が小さく線材も細いものだと、線材
の先端が曲がってコアの壁や既に巻かれた線材に当たっ
たりし、コアの孔に挿入できないことがある。(Prior art) When a toroidal coil is manufactured, the operation of inserting a wire through a hole in a ring-shaped core is repeatedly performed. In this case, if the core has a small hole diameter and the wire is thin, the tip of the wire may be damaged. It may bend and hit the wall of the core or the already wound wire, and may not be able to be inserted into the hole in the core.
そこで、線材の先端にピアノ線等を接着して線材の挿
通を容易とする巻線方法や、線材の先端に挿入用治具を
取り付けて挿通を行う巻線方法が提案されている（特開
昭63−154311号、−112374号公報等参照）。Therefore, a winding method has been proposed in which a piano wire or the like is adhered to the end of the wire to facilitate insertion of the wire, or a winding method in which an insertion jig is attached to the end of the wire for insertion. (See, for example, JP-A-63-154311 and -112374).
（発明が解決しようとする課題） しかしながら、線材の先端にピアノ線等を接着する方
法では、線材（銅線）より剛性が上がるため、コア孔へ
の挿通は確実となるが、線材にピアノ線等を接着する工
程が必要であり、また巻線中にピアノ線との接着部がは
がれたりするという心配もある。(Problems to be Solved by the Invention) However, in the method of bonding a piano wire or the like to the tip of a wire, rigidity is higher than that of a wire (copper wire), so that the wire is securely inserted into the core hole. And the like, and there is a concern that the bonded portion with the piano wire may come off during winding.
また、挿入用治具を用いる法では、切れやすい線材を
治具に確実にクランプするのが難しく、また治具の径は
線材よりも太いため、コア孔が小さい場合には挿通が困
難である。Also, in the method using an insertion jig, it is difficult to reliably clamp a wire that is easy to cut to the jig, and since the diameter of the jig is larger than the wire, it is difficult to insert the wire when the core hole is small. .
この発明は、このような問題点を解決することを目的
としている。An object of the present invention is to solve such a problem.
（課題を解決するための手段） この発明は、リールから引き出した線材の先端側をか
せ繰りし、このかせ繰り部を撚って撚部を形成し、形成
した撚部の途中を切断し、この切断後、その切断端部を
先端にして線材をリング状のコアの孔に繰り返し挿通
し、巻線する。(Means for Solving the Problems) According to the present invention, the leading end side of a wire drawn from a reel is twisted, the twisted portion is twisted to form a twisted portion, and the formed twisted portion is cut in the middle. After this cutting, the wire is repeatedly inserted into the hole of the ring-shaped core with the cut end as a tip, and wound.
（作用） したがつて、線材の先端部の剛性が高まるため、線材
が細くコアの孔径が小さい場合でも、コア孔への挿通を
確実に行うことができ、巻線を容易に行える。(Operation) Accordingly, since the rigidity of the distal end portion of the wire is increased, even when the wire is thin and the core has a small hole diameter, the wire can be reliably inserted into the core hole, and the winding can be easily performed.

A hook 11 is provided with a pin 11 erected at 10 and a shuttle 13 provided with two guide holes 12. The hook 9 is rotatable together with the hollow shaft 8 by a driving device (not shown), and the pin 11 is turned by a driving device (not shown). It is formed so as to be tiltable toward the hook 9 via the arm 10. The shuttle 13 is attached to a chain 14 hung between two chain wheels (not shown) connected to a driving device (not shown), and is formed so as to be movable on a predetermined annular track around the hook 9 and the pin 11. Have been.

知のもので良い。The winding machine 4 includes a holder 15 for the wire 2 and a cutter 16, and further includes a winding mechanism (not shown). This winding mechanism may be a known one.
即ち、リール１から引き出された線材２は、第３図
（Ａ）のように撚線機３のシャトル13のガイド穴12を通

される。That is, the wire 2 pulled out from the reel 1 passes through the guide hole 12 of the shuttle 13 of the twisting machine 3 and further passes through the hole 17 of the hollow shaft 8 to which the hook 9 is attached as shown in FIG. It is pulled out to the machine 4 and its tip is held by the holding unit 15.

Is formed.
次に、撚部５が形成されると、アーム10を介してピン

され、撚部５が巻線機４に導かれる。Next, when the twisted portion 5 is formed, a pin is inserted through the arm 10.
While tilting the wire 11, the wire 2 is further drawn out to the winding machine 4, and the twisted portion 5 is guided to the winding machine 4.

通することで巻線が行われる。Then, the twisted part 5 guided to the winding machine 4 has a cutter 16 on the way.
The wire 2 is wound around a ring-shaped core 6 with the cut end as a tip. In this case, as shown in FIG. 4, winding is performed by repeatedly inserting the wire 2 into the hole 19 of the core 6 with the cut end 18 at the tip.

行うことができる。By forming the distal end of the wire 2 in this manner, the rigidity of the distal end of the wire 2 is increased. In this case, since a plurality of skeined wires are twisted to form a tip, it is bent even when the tip of the wire hits the core wall or already wound wire compared to a single wire. The rigidity against buckling in the linear direction is increased. Therefore, even when the wire 2 is thin and the core hole 19 is small, it is possible to surely insert the wire into the core 19.
また、線材２の先端部を撚ることにより、曲がりのな

端部の位置を一定に保つことができ、挿通を容易にかつ
より確実に行うことができる。Also, by twisting the tip of the wire 2, a straight tip without bending can be obtained, so that the position of the tip of the wire 2 can be kept constant at the time of insertion, making insertion easier and more reliable. Can be done.
また、従来例のように線材とピアノ線等との接着工程
等が無いため、自動化が容易であり、好適である。Further, since there is no bonding step between the wire and the piano wire or the like as in the conventional example, automation is easy and preferable.
また、巻線作業と撚線作業とを並行して行えるため、
高い生産効率が得られる。即ち、先端部を撚った線材を
所定長さに切断後、巻線工程に移すことで、次の撚線作
業と重なることがない。In addition, since winding work and stranded wire work can be performed in parallel,
High production efficiency can be obtained. That is, the wire having the twisted tip is cut into a predetermined length and then transferred to the winding process, so that the next twisting operation does not overlap.
なお、本実施例では、切断した撚部５がコア６の壁や
既に巻かれた線材２に当たると、撚部５がばらけること

接着剤を塗布すればばらける心配はなく、対応は容易で
ある。In the present embodiment, when the cut twisted portion 5 hits the wall of the core 6 or the already wound wire 2, the twisted portion 5 may be separated. There is no need to worry about disintegration by applying a suitable adhesive, and it is easy to respond.
