DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle type deflection coil used for a deflection yoke mounted on a color cathode ray tube such as a television receiver or a computer display.
More particularly, the present invention relates to a saddle-type deflection coil winding machine and a saddle-type deflection coil winding method.

2. Description of the Related Art As a conventional winding machine for winding a saddle type deflection coil, for example, a winding machine schematically shown in FIG. 5 has been widely used. Here, FIG. 7A is an explanatory view of a main part of the winding machine by a plan view, and FIG. 7B is an explanatory view of a main part of the winding machine by a front view. In this winding machine, the convex and concave winding forms 1 and 2 are mounted on the rotating plates 1A and 2A, respectively, and pressure is applied from the left and right and up and down to combine the convex and concave winding forms 1 and 2. Then, the rotary plates 1A and 2A are driven to rotate in the direction indicated by an arrow A in the figure, and the coil wire 4 is wound around the space 3 of the convex and concave winding forms 1 and 2 to form a saddle type deflection coil. Had been manufactured. In addition, in this winding machine, the convex and concave winding forms 1,
Wire nozzle 5 for guiding coil wire 4 to space 3 of 2
A is used, and the electric wire nozzle 5A is located on the rotation shaft and the extension of the center 6 of the convex and concave winding forms 1 and 2, and as shown in FIG. In most cases, screws 9 were fixed and fixed via the mounting frame 5B. Also, in this winding machine, it is difficult to smoothly guide the coil wire 4 into the space 3 of the convex and concave winding forms 1 and 2 only with the convex and concave winding forms 1 and 2. , 2 need to be provided with spiral winding guide portions 7 (splashes) for guiding the coil wire 4 to the left and right, respectively.

[0003] However, since the winding guide portion 7 is easily increased in size and increased in weight, a large rotating plate 1 is required.
The rotation drive system for rotating A and 2A must also be able to withstand the corresponding strength. In the step of winding the coil wire 4, the coil wire 4 is always wound on the space 3 while being in contact with the winding guide 7, so that the mechanical strength (insulation layer) for the coil wire 4 is increased. However, there was a drawback that the temperature decreased.

[0004]

Therefore, in order to solve this problem, for example, a traverse type (or fryer type) winding machine whose winding method is schematically shown in FIG. 4 has been adopted. Was. Here, (a) is an explanatory view of a main part of the winding machine in a plan view, (c) is an explanatory view of a main part of the winding machine in a front view, and (b) is a rotation of an electric wire nozzle. FIG. This traverse type winding machine is characterized in that the winding guide portion required in the conventional winding machine is not required and the fixed electric wire nozzle 5A is configured to be rotated. The saddle type deflection coil can be wound without lowering the strength (insulating layer). However, in the traverse-type winding machine (or the flyer-type winding machine), since the electric wire nozzle 5 is rotated, there is a problem that the coil wire 4 is twisted with the rotation of the electric wire nozzle 5. When the coil wire 4 is formed of one single wire, the twist is only one twist, and has almost no effect on the coil wire 4. However, when the coil wire 4 is formed of a plurality of insulated wires, The plurality of coil wires 4 are simultaneously twisted with the rotation of the electric wire nozzle 5, so that the coil wire 4 as a whole tends to be a kind of twisted wire or Litz wire aggregated wire, so that the diameter of the coil wire 4 is large. There was a difficulty in changing to a tendency. This phenomenon occurs in the case where the number of coil wires 4 is plural, even with the rotation direction of the electric wire nozzle 5,
Particularly in a recent deflection yoke, two coils whose rotation directions are opposite to each other are used as a pair to prevent ringing or the like, but there is a problem that coils having different twist directions are manufactured. The effect of twisting of the coil wire 4 also depends on the winding direction of the deflecting coil.
At the turn, twisting is likely to occur, and the diameter of the coil wire 4 is relatively large, so that the coil wire 4 is less likely to enter the space 3 of the winding forms 1 and 2, and a coil that does not perform normal winding is manufactured. There was a drawback that was being done. further,
This phenomenon occurs because there is a coil in the opposite rotation direction even in a pair of coils, and it is difficult to produce a coil having different characteristics between a coil that easily occurs on the right side of the coil and a coil that easily occurs on the left side of the coil. was there. Also,
The coil wire 4 on the right and left sides of one coil
However, there is a problem in that the magnetic properties of the manufactured coil become unbalanced because the winding forms 1 and 2 have different easiness of entering the space 3.

Therefore, an object of the present invention is to provide a traverse type winding machine (flyer type winding machine), in which even when a coil material composed of a plurality of insulated wires is wound, the wire material twists due to rotation of the wire nozzle. An object of the present invention is to provide a winding machine and a winding method capable of manufacturing a saddle-type deflection coil having a uniform coil magnetic field characteristic without being affected by the above.
