  Next, with reference to FIG. 3, a wire forming operation and a winding operation by the winding apparatus 100 will be described. FIG. 3 is a diagram showing the wire forming operation and the winding operation in chronological order. The following operations are automatically controlled by the controller 67 mounted on the winding device 100.

  FIG. 3A is a diagram showing a state immediately before the winding operation to the winding core 3 is completed and a new winding operation is started. As shown to Fig.3 (a), the front-end | tip part of the two wire rods 4a and 4b drawn | fed out from the nozzle 11 is the bent state. From this state, the forming operation of the wire starts.

  First, as shown in FIG. 3 (b), by operating the clamp moving mechanism 32, the clamp support portion 35 is moved and the tip portion of the wire 4 is held by the clamp 31.

  As shown in FIG. 3C, by operating the nozzle moving mechanism 12, the nozzle 11 is moved away from the clamp 31 and the wire 4 is fed out from the clamp 11 by a predetermined length. At this time, the predetermined length of the drawn wire 4 is in a state where the insulating film is peeled off by the film peeling device 54, and the peeling portion 70 is formed on the wire 4.

  As shown in FIG. 3D, by operating the chuck moving mechanism 34, the chuck support portion 45 is moved, and a predetermined distance from the tip of the nozzle 11 in the wire 4 to the peeling portion 70 where the insulating film is peeled off is obtained. The position is held by the chuck 33.

  As shown in FIG. 3 (e), by operating the chuck moving mechanism 34, the chuck 33 is moved in the direction away from the nozzle 11 (Y-axis direction) to pull out the wire 4 from the nozzle 11, and the clamp moving mechanism 32 is moved. By operating, the clamp 31 is moved in the direction (X-axis direction) perpendicular to the moving direction of the chuck 33. Thereby, the wire 4 will be in the state bent at substantially right angle. Thus, by operating the chuck moving mechanism 34 and the clamp moving mechanism 32, the wire 4 is bent with the position held by the chuck 33 as a fulcrum.

  Here, a bent portion 71 is formed in the wire 4 by bending the wire 4. Thereby, the position of the peeling direction 70a of the inner side wire 4a and the peeling part 70b of the outer side wire 4b will shift | deviate. Therefore, when peeling off the insulating film, the position of the film peeling device 54 provided for each wire 4 is shifted in the longitudinal direction of the wire 4 by operating the film peeling device moving mechanism 55, and the inner wire The positions in the longitudinal direction of the wire between the peeling portion 70a of 4a and the peeling portion 70b of the outer wire 4b are shifted in advance. Thereby, even when the wire 4 is bent, the shift | offset | difference of the peeling part 70 of the inner wire 4a and the outer wire 4b can be prevented.

  Next, as shown in FIG. 3 (f), the peeling portion 70 of the wire 4 is cut by a cutter 43 provided in the clamp moving mechanism 32. As a result, the wire rod 4 has a forming portion 73 including a straight portion 72 that is linearly drawn from the nozzle 11 and a lead portion 10 that is continuous with the straight portion 72 through the bent portion 71 and has a peeling portion 70 at the tip. Will be formed.

  After cutting off the peeling portion 70, the chuck 33 holding the wire 4 is released, and the restraint of the forming portion 73 fed out from the nozzle 11 is released. Then, the forming unit 73 is moved toward the core 3 by operating the nozzle moving mechanism 12.

  As shown in FIG. 3 (g), the linear portion 72 of the wire rod 4 is arranged on the winding drum portion 8 of the core 3 along the inner surface 9 b of the flange portion 9, and the lead portion 10 of the wire rod 4 is placed on the flange portion 9. The forming part 73 is locked to the flange part 9 by passing through the provided opening part 9a. Since the bent part 71 of the forming part 73 is substantially perpendicular, the forming part 73 abuts against the flange part 9 without a gap.

Next, as shown in FIG. 3 (h), the wire holding member 14 disposed on the winding jig 7 is moved toward the core 3, and the lead portion 10 is accommodated in the groove 51 of the wire holding member 14. To do. The wire holding member 14 moves until the notch 14c is engaged with the flange 9. In a state in which the notch portion 14c is engaged with the flange portion 9 , the lead portion 10 is guided to the groove portion 51 through the notch portion 14c, and the convex portion 14d of the wire rod holding member 14 is an opening of the flange portion 9. It will be in the state where it penetrated the part 9a and was arranged on the winding drum part 8. Thereby, since the lead part 10 of the forming part 73 is held by the wire holding member 14, the forming part 73 comes into contact with the winding body part 8 without any gap in the subsequent winding operation, and is stable. Winding becomes possible.

  The operation shown in FIG. 3 (i) and thereafter shows the winding operation of the wire 4 around the core 3. First, as shown in FIG. 3 (i), the spindle shaft 2 is rotated to rotate the core 3, and the nozzle moving mechanism 12 is operated to move the nozzle 11 in the axial direction of the spindle shaft 2 (X-axis direction). As a result, the wire 4 is wound around the winding body 8 of the winding core 3. Here, since the end face of the convex part 14d of the wire holding member 14 is formed to be inclined, the wire 4 is guided and wound around the end face of the convex part 14d.

  As shown in FIG. 3 (j), the wire rod 4 fed out from the nozzle 11 is twisted to arrange the twisted wire rods 4 by operating the nozzle rotating mechanism 26 and rotating the nozzle support plate 15, as shown in FIG. Replace. Thereby, it can prevent that a wire is wound in multiple and can obtain a compact multilayer coil.

  After the winding of the predetermined number of layers is completed, the wire holding member 14 is moved backward to open the wire 4 as shown in FIG. Further, the nozzle moving mechanism 12 is operated to guide the nozzle 11 from the opening 9a of the flange 9 to the outside of the core, thereby drawing the wire 4 from the opening 9a to the outside of the core.

  Then, as shown in FIG. 3 (l), the peeling portion 74 of the wire 4 from which the insulating film has been peeled off by the film peeling device 54 is cut by the cutter 52 provided in the chuck moving mechanism 34.

  The operation described above is an operation of one cycle, and when the next cycle is started, the operation returns to FIG.

  According to the first embodiment described above, when starting winding a plurality of wires 4 around the core 3, the wires 4 are bent in advance so as to be engaged with the collar opening 9 a of the core 3, and Since the lead part 10 of the stopped forming part 73 is held in the winding body part 8, the wire 4 can be wound around the core 3 without a gap even when there are a plurality of wires. Therefore, regular and stable winding can be performed on the winding core 3.
