And as shown in Figure 9, while winding tool 18 rotates, nozzle 31 rotates to the direction identical with the direction of rotation of winding tool 18 with the rotary speed of faster than the rotary speed of winder 21 2 times.As a result, draw at wire rod the core 11 that in operation, derivative wire rod 12 is extremely arranged in this winder 21 by rollback, and be wound in core 11 from the wire rod 12 that nozzle 31 is newly sent, form α winding coil 17.
Utilize motor 32 (Fig. 1) that the rotating parts 39 being provided with nozzle 31 is rotated thus this nozzle 31 is rotated.Thus, nozzle 31 rotation around core 11.This nozzle 31 pivotal direction around core 11 and speed identical with the direction of rotation of winder 21 is 2 times of the rotary speed of winder 21.
Thus, the wire rod 12 newly sent from nozzle 31 with from clamping device 53 together with the wire rod 12 of the direction rollback shown in the solid arrow of Fig. 9 coiling simultaneously in core 11.Now, the wire rod 12 newly sent from nozzle 31 is sent along the flange part 11b of the opposing party of core 11, is partial to the flange part 11b of this opposing party and is wound in reel portion 11c.
On the other hand, winding tool 18 rotates by the motor 23 being installed on pedestal 13 shown in Fig. 1.Make to store thread-clamping device 53 core 11 that derivative wire rod 12 is extremely arranged in this winder 21 by rollback away from this winder 21 by drawing in operation at wire rod.
If the rollback of reality starts, Ze Xu line travel mechanism 54 is to be made clamping device 53 close to winder 21 with this by the speed that the speed of the wire rod 12 of rollback is roughly equal.Thus, wire rod 12 can not bend between clamping device 53 and core 11, and the coil of a side that can prevent obtained α from reeling in coil 17 bloats.
Now, helical spring 60 (Fig. 6) stores thread-clamping device 53 exert a force to the direction away from winding tool 18 to this, be absorbed in by the error produced between the amount of the wire rod 12 of rollback and the amount of movement of clamping device 53, reliably prevent the bending of the wire rod 12 between clamping device 53 and core 11.Now, the wire rod 12 held by clamping device 53 along the flange part 11a of a side of core 11 by rollback to reel portion 11c, the flange part 11a along this side is wound in reel portion 11c.
Thus, α winding coil 17 is formed.The wire rod 12a at winding top and the wire rod 12b both sides of winding terminal are all positioned at the most peripheral (Fig. 9) of α winding coil 17.Even if the wire rod 12a at the winding top part that to be the rotation by winder 21 in the wire rod 12 of being drawn in advance by clamping device 53 also not residual by coiling.The wire rod 12b of winding terminal be from the wire rod 12 that nozzle 31 is newly sent, be not wound in core 11 and residual part.
And the wire rod 12 forming α winding coil 17 is the covering wires of the insulated cladding had from melting, therefore, by utilizing not shown hot blast generator to blow hot blast, is bonded to each other by adjacent wire rod 12, obtained α winding coil 17 can be prevented defeated and dispersed.
< wire rod cuts off operation >
Cut off in operation at wire rod, the wire rod 12 at α winding coil 17 two ends is cut to specific length.This cut-out utilizes cutting-off tool plate 73 to carry out, and the wire rod 12a at winding top is cut off with the wire rod 12b of winding terminal simultaneously.
First, the cut-out of the wire rod 12a at winding top is described.When carrying out this cut-out, Xu Xian travel mechanism 54 makes to store thread-clamping device 53 and moves, and as shown in Figure 10, makes the wire rod 12a storing the winding top that thread-clamping device 53 extends to core 11 from this pass through the slit 71a of the side formed at wire rod holding plate 71.Like this, this wire rod 12, contacting from the extension part 71b arrival stage of parallel portion 71c with the point of a knife 73a of cutting-off tool plate 73, is then pressed further into slit 71a.As a result, the wire rod 12a at this winding top is cut off.
And, be locked to the state that the ora terminalis of wire rod 12a after it is cut-off that cutting-off tool plate 73 extends is inserted in the slit 71a of wire rod holding plate 71 from the core 11 forming winding tool 18.
Arrive α via slit 71a under the state that wire rod 12a remains in parallel portion 71c at its ora terminalis to reel coil 17.In this case, wire rod holding plate 71 is positioned at compares the position of α winding coil 17 by oblique below, and therefore, the ora terminalis of wire rod 12a becomes the state that card is hung on parallel portion 71c.
