であった。To wrap a wire in a toroidal shape around a donut-shaped core, hold the tip of the wire, pull it through the inside of the core until the back end of the wire wraps around the cross section of the core, and then wrap it around the outside of the core. It is necessary to repeat the reciprocating motion of moving the tip of the wire in the opposite direction for several turns of the coil, and its production requires a long time and labor. The length of wire required when wound around is 5 m, and although the length is gradually decreasing, reciprocating this long wire requires a large work area and a long time. Furthermore, it is difficult to wind coils at equal intervals around a circular core, and it is extremely difficult to economically produce large quantities of toroidal coils with uniform performance.

ルコイルが成形される。The present invention applies the principle that a wire fed out in a linear direction through a nozzle is formed into a spiral shape by the resistance of one or more coiling bins fixed at the exit end of the nozzle. The wire is fed out at high speed and is automatically and continuously formed into a helical shape and wound around the core, forming a toroidal coil in a short period of time.

らコア２の断面に連続して巻き付いていく。First, referring to FIG. 1, a clamp 1 clamps and fixes a core 2. The linear nozzle 3 is fixed at a position in contact with the outer circumference of the core 2 . The wire 4 is continuously fed out from the hole of the nozzle 3 by the frictional force of a pair of feed rollers 5, and is formed into a helical shape by the resistance of one or more coiling bins 9 fixed at the exit end of the nozzle. It wraps continuously around the cross section of 2.

動を瞬時に停止させれば所定のコイル巻数を得られる。The number of turns of the coil is controlled by a length gauge 6 (number M in the first drawing). The required length of the wire until the tip of the wire wound a predetermined number of turns reaches a predetermined position on the wire holder 7 (see Figure 2) is set in advance, and the wire 4 is fed by the set length. A predetermined number of coil turns can be obtained by instantly stopping the operation of the feed roller 5.

It shows how to process. When the feeding motion of the wire 4 is stopped, the wire holder 7 pinches the tip of the wire 4. In order to form a lead terminal part on the coil, the wire holder 7 pulls out the tip of the wire by a predetermined length, and at the same time, the feed roller 5 operates and the wire holder 7
The wire 4 is fed at the same speed as the withdrawal speed of. When the wire holder 7 reaches a predetermined position, the pulling movement is stopped, and at the same time, the feeding movement of the feed roller 5 is also stopped, and one of the lead terminals is formed. To form the other lead terminal, move the nozzle 3 in the same direction and the same distance as the previously formed lead terminal while sliding the wire 4 through the hole in the nozzle 3, and use the cutter 8 to Nozzle 3
By cutting the wire at the end, a toroidal coil having a pair of lead terminals with a predetermined number of turns and a predetermined length is completed.
