Is arranged to be movable back and forth by a cylinder 24a.

Since this embodiment has the above-mentioned structure, referring to FIGS. 8 to 16, first, as shown in FIG. 8, the end portion of the wire W drawn from the wire supply unit 4 through the nozzle 8 is a bobbin. The bobbin B is fastened to the B. In this state, the bobbin B is swung about the bobbin axis _BL by the bobbin swivel mechanism 2, and by this swiveling operation, the wire W is wound around the winding groove a on the screen side of the bobbin for about half a turn. After the bobbin B has stopped turning, as shown in FIG. 9, the nozzle rotation mechanism 12 causes the insertion / removal member 11 and the attachment member 14 to move together to the nozzle axis N _L.
In the state shown in FIG.
As described above, the bobbin moving mechanism 3 and the vertical moving mechanism 9 cause the nozzle portion 8 to sequentially descend along the winding groove c having the arcuate inner surface with the combined movement in the X-axis direction and the Z-axis direction. By the roll moving mechanism 17, the guide roll 15 gradually follows the NZ direction in the up-down direction so that the wire W can match the winding position on the bobbin B, in this case, the tangential direction of the bottom surface of the winding groove c. It will move down to.

Then, as shown in FIG. 11, when the lower end portion of the nozzle portion 8 is pulled out from the neck side of the bobbin B, the hooking mechanism 19 operates and C of the supporting member 20 and the holding member 21.
The pair of guide members 23 by movement in the X and CZ directions
The wire W is positioned in the insertion gap 22 between them, and in this state, the guide roller 24 protrudes as shown in FIG. 12, and the wire W is hooked by the guide roller 24 to the winding groove b on the neck side as shown in FIG. In this state, the bobbin B is swung by the bobbin swivel mechanism 2 about the bobbin axis _BL, and the wire W is wound around the winding groove b on the neck side of the bobbin for about half a turn. After the turning is stopped, as shown in FIG.
Ascending in the axial direction, as shown in FIG.
As a result, the insertion / removal member 11 and the mounting member 14 together rotate horizontally about the nozzle axis N _L around NR, and in this state, the nozzle portion 8 is moved by the bobbin moving mechanism 3 and the vertical movement mechanism 9 as shown in FIG. With the combined movement in the X-axis direction and the Z-axis direction, the guide roll 15 is sequentially raised along the winding groove c having an arcuate inner surface. At this time, the guide roll 15 is wound around the bobbin B by the roll moving mechanism 17. In this case, the wire material W follows the NZ direction in the vertical direction so that the wire W matches the tangential direction of the bottom surface of the winding groove c as much as possible, and gradually moves up and then down.

16 again, that is, in the state of FIG. 8 again, the same applies to the winding groove a on the screen side, the winding groove b on the neck side, and the winding groove c on the arc-shaped inner surface. The winding operation is repeated a predetermined number of times, and the wire W is lapped a plurality of times by the wrapping operation including the insertion and removal of the nozzle portion from the bobbin B of the integral type bobbin B to complete the winding work of the deflection yoke. .

Therefore, from the wire rod supply section 4 to the nozzle section 8
The wire W fed out through the bobbin B of the nozzle portion 8 is an integral bobbin B having a winding position consisting of a winding groove a on the screen side, a winding groove b on the neck side and a winding groove c on the arcuate inner surface. The wire is automatically wound by a revolving operation including insertion and removal with respect to the wire, the winding work can be automated, and the work can be speeded up. In particular, the wire W from the wire supply part 4 to the bobbin B is nozzle 8 The guide roll 15 provided at the tip end of the bobbin B guides the detour.
Since the wire rod W up to the point W is inserted and guided through the guide hole 16a of the fixed guide 16, it is possible to bend the wire rod by the guide rolls 15 and to suppress the damage to the wire rod W as much as possible, and the good winding can be performed. It is possible to obtain a linear state, and to fix the fixed guide 16 to the winding groove c on the arc-shaped inner surface as much as possible.
Can be located close to the bottom of the
It is possible to obtain good derivation and guiding effect for the winding and perform good winding.

At this time, the guide roll 15 is moved to the position shown in FIG.
15 and the roll moving mechanism 17, as shown in FIGS. 15 and 16, according to the winding position on the bobbin B.
Since the wire rod W moves in the insertion / removal direction, the wire rod W matches the tangential direction of the bottom surface of the winding groove c on the arcuate inner surface of the bobbin B as much as possible, and the wire rod W can be wound well by that much. Since the nozzle portion 8 is rotated by the nozzle portion rotating mechanism 12 around the axis line in the insertion / removal direction of the nozzle portion 8 in accordance with the winding position with respect to the bobbin B, the flexibility with respect to the winding position is increased, and the better it is. Good winding work can be performed.

The present invention is not limited to the above embodiment, and the wire rod supply portion 4, the nozzle portion 8 and other structures are appropriately modified and designed.

Further, in the above-mentioned embodiment, the winding structure in which one wire W is wound around the bobbin B is applied, but it can be applied to a structure in which a large number of wires are simultaneously wound. In this case, the winding tube 6 and the tension control mechanism 7 are installed. The numbers are arranged in parallel according to the number.
