Surround it as shown by the imaginary line. That is, when the member 231 extends in the arrow X1 direction, the members 219a and 219a linearly move in the directions of the arrows E1 and E against the force of the elastic body 218. As a result, the guide rollers 11a and 11b are in a state of intersecting each other so as to sandwich the guide roller 12 therebetween.
The wire W is guided through the inside of these guide rollers 11a, 11b, 12 and is entangled with the tip 225.
By advancing along the arrow X1 direction, the wire W can be sandwiched and fixed.

By the cooperation of the guide unit 103 of FIG. 6 and the nozzle 19a of the nozzle unit 19, the wire rod is first tied and fixed to the pin NP. Then, the nozzle 19a is lifted up from the bobbin N and guides the wire W to the opening groove N1 side as shown in FIG. At this point, the rods 41a, 41a of the actuator 41 in FIG. 3 contract in the direction of arrow X2. As a result, the force of the elastic body 218 acts on the member 231 side, so that the guide rollers 11a, 11b, 12 retreat to the arrows E1, E, respectively. That is, the intersecting state of the three guide rollers is released. Then, the wire W enters between the guide rollers 11a, 11b, 12 and again guides the guide rollers 11a, 11b, 12 with the arrow E1,
By extending in the direction of E, the wire W is surrounded and entangled, and the tip 225 is extended in the direction of arrow X1. As a result, the wire W is entwined with the guide roller and fixed by the tip 225.

When the motor M4 of the holder unit 50 shown in FIG. 1 is operated, the bobbin N shown in FIG. 7 is indexed in the direction of a predetermined angle arrow R1. As a result, the wire rod W moves into the opening groove N1.

3 and N3, and as shown in FIG.
a enters the bobbin N. Moreover, the guide rollers 11a and 11b of the guide unit 103 shown in FIG.
03 moves to the side of the neck groove N2 as shown in FIG. Again, the guide rollers 11a, 1 of the guide unit 103 shown in FIG.
1b and 12 are in an intersecting state, and the entanglement tip 225 moves toward the guide roller to press and fix the wire W.

Then, as shown in FIG. 10, the guide unit 103 lifts the wire W in the arrow U direction, and the bobbin N is indexed in the arrow R direction by a predetermined angle. As a result, the wire W is wound in the neck groove N2 and is shown between the next locking pieces N4 and N4. Then, when the intersecting state of the guide rollers 11a, 11b, 12 of the guide unit 103 is released again, the wire W separates from the guide unit 103 and fits between the locking pieces N4, N4. By performing the winding in the opening groove N1, the winding in the inner peripheral portion of the bobbin N, and the winding in the neck groove N2 in this procedure, the winding of the predetermined pattern wire can be performed.

In the above-described winding operation, the bobbin N is indexed by a predetermined angle with respect to the central axis CL in FIGS. 7 and 10, for example, as shown in FIG. When rotating around, the wire W is guided in contact with only the guide rollers 11a and 11b. In addition, as shown in FIG.
Is rotated in the counterclockwise direction R1, the wire W is guided only by the guide roller 12. That is, the wire W
12 moves in the -Y direction as shown in FIG. 12, the guide rollers 11a and 11b take charge of guiding the wire rod W. When the bobbin N moves in the + Y direction, the guide roller 12 takes charge of guiding the wire W as shown in FIG.

By using the pair of guide units 103 shown in FIGS. 3 and 4, the bobbin N can be wound around the opening groove N1, the neck groove N2 and the inner circumference of the bobbin N. it can. Moreover, when the conventional almost C-shaped hook is used, the hook should be set according to the rotating direction of the bobbin.
It was necessary to rotate 0 ° to change the direction of the hook,
The guide unit 103 of the present invention does not require such a direction change and the guide roller 11 of the guide unit 103 is
The wires a, 11b and 12 can reliably guide the wire W even when the bobbin N is indexed clockwise or counterclockwise. Moreover, when the conventional hook type guide unit is used, the opening groove N1 of the bobbin N is used.
It is necessary to prepare one set of guide units corresponding to the above and another guide unit for the neck groove, but one set of guide unit 103 in the embodiment of the present invention is prepared. Then, the wire W can be wound around the opening groove N1 and the neck groove N2.

The conventional hook-type guide unit requires an operating mechanism for turning the guide unit by 180 ° as described above and a mechanism for causing the hook of the guide unit to hook the wire. Such a mechanism can be omitted in the embodiment of the present invention. Therefore, the wire winding time can be shortened. As described above, in the embodiment of the present invention, the wire W can be stably and efficiently supplied to the bobbin and wound regardless of the winding portion of the bobbin N or the index direction of the bobbin N. Therefore, the quality of the product of the deflection yoke wound with the wire can be improved. By the way, the present invention is not limited to the above-mentioned embodiments. In the embodiment described above, the wire rod is wound around the bobbin of the deflection yoke for the cathode ray tube of the television receiver, but the present invention is applicable to the case where the wire rod is wound around the work in other fields. Can also be applied.
