2. Description of the Related Art Conventionally, since a deflection yoke frame of a deflection yoke used in a television receiver is formed by combining two halves into a funnel shape, it is relatively easy to wind a saddle type coil or the like. However, in the high-definition television receiver, since the deflection yoke frame is completely integrated in a funnel shape, some kind of ingenuity is required for the winding device for winding and the winding method.

That is, a deflection yoke frame 21 for high definition
Is configured as shown in FIG. The large opening 21a side of the funnel-shaped deflection yoke frame 21 is arranged on the fluorescent surface side of the cathode ray tube and the small opening 21b side is arranged on the neck side of the cathode ray tube.

On the opening 21a side of the deflection yoke frame 21, there are provided a plurality of locking pieces 21c and a plurality of winding grooves 21d and one opening-side circumferential groove 21e.

Similarly, the opening portion 21b on the neck portion side is also composed of a plurality of locking pieces 21f, a winding groove 21g, and an opening circumferential groove 21h.

A side sectional view of such a deflection coil frame 1 is shown in FIG.
It is shown in A. Reference numerals 4 and 5 denote a nozzle unit and a guide unit, which will be described later, and the wire 9 eaten by the nozzle 18 of the nozzle unit 4 is lowered through the center hole of the deflection yoke frame 21 and provided at a predetermined position of the deflection yoke frame 21. The operation of tying the tip of the wire 9 around the entangled portion 21K is performed. Although not shown, this binding operation is performed by a separately provided binding device. Normally, if a entanglement pin or the like is erected on the upper side of the work itself, the nozzle unit 4 itself is rotated for entanglement. However, in the case of a work as shown in FIG. 17A, the nozzle unit 4 is rotated. However, since the wire 9 cannot be wound around the entanglement portion 21K, it is necessary to dispose another entanglement mechanism in the winding device.

In order to wind the saddle type coil 9a as shown in FIG. 17B around the deflection yoke frame 21 based on the wire 9 entwined in this way, the nozzle 18 of the nozzle unit 4 is moved upward from the center hole and the wire 9 is locked. Hook on the piece 21c. At this time, the guide tip of the guide unit 5 described later guides the wire. Next, the wire 9 is wound along the opening circumferential groove 21e,
It is locked by the next locking piece 21c '. Even in this state, the operation of the guide unit 5 is required. When the winding of the opening circumferential groove 21e is completed, the nozzle 18 of the nozzle unit 4 descends again, and the wire 9 is hooked on the locking piece 21f to move the wire 9 to the next position along the opening circumferential groove 21h on the small diameter side. Stop 21
The operation of hooking on f'is performed. Locking piece 2 at this time
In order to perform the locking operation of the wire 9 to the 1f and 21f ', it is necessary to lower the guide unit 5 in the downward direction in FIG. 17A.

When the guide unit 5 is lowered in this manner, the height of the deflection yoke frame 21 is large, so that the time for lowering (or moving up) the guide unit 5 becomes long. We proposed a winding machine as shown in.
