The spindle 3 is projected in the direction of the winding nozzle 34 while not rotating, and the terminal _C2 of the bobbin B is moved to the position of the winding nozzle 34. At this time, the spindle 3 is rotationally positioned so that the winding nozzle 34 can pass through a predetermined slit d of the bobbin B.
When the terminal C ₂ of the bobbin B moves to the position of the winding nozzle 34, the drive device 2 for rotating the winding part 19

When the winding nozzle 34 moves, the swing drive device 28 operates to connect the winding nozzle 34 to the terminal.
Swirl around C ₂ and wrap wire Y. (1
(Figures 1-2) At this time, the reciprocating drive device 13 operates to move the spindle 3 by the winding pitch of the wire. (Fig. 11-3) When the wire Y is wound around the terminal _C2 , the drive device 38 of the clamping portion 36 is activated to project the shaft 39 together with the hollow shaft 37 and move it to the wire clamping position. At this time, there is a gap between the end surface of the hollow shaft 37 and the collar of the shaft 39. The hollow shaft 37
When the flange of the shaft 39 moves to a predetermined position, the lifting device 21 and the drive device 24 of the winding section 19 are activated to move the winding nozzle 34 and move the wire Y between the hollow shaft 37 and the flange of the shaft 39. Hang it in between. When the wire Y is hooked, the drive device 38 is activated and the actuation mechanism 40 is activated.
As a result, only the shaft 39 is moved back, and the wire Y is held between the end surface of the hollow shaft 37 and the collar of the shaft 39. When the wire Y is clamped, the drive device 54 of the cutting section 52 is activated, and the cutter 53 is projected to the position of the wire Y between the clamping section 36 and the terminal _C2 of the bobbin B to cut the wire Y (11th- Figure 8) Repeat each of the above operations sequentially to connect each terminal C ₃ , C ₄ . . . of bobbin B and the wire Y to the winding section f.
Winding is performed. When the wire rod winding operation is completed, the tape winding device 56 is activated to wind the tape around the winding portion f of the bobbin B at a predetermined position. When the tape winding operation is completed, the lifting device 21 of the winding section 19 is activated to raise the winding nozzle 34 to the standby position. When the winding nozzle 34 moves to the standby position, the spindle part 1

When the presser 50 returns to the standby position, the bobbin supply device 56 operates, rotating the chuck 58 in which the bobbin B' has been inserted and moving it to the bobbin supply and take-out position, and at the same time, the new bobbin inserted during the winding operation. Move B to the bobbin delivery position. The winding bobbin B' located at the bobbin supply/take-out position is extracted from the chuck 58 by an operator or a take-out device to obtain a coil having been wound thereon. On the other hand, a new bobbin at the bobbin delivery position is wound by the winding machine by repeating the above operation.
