When the winding direction is changed, the winding direction may change and the winding 11 may be misaligned and wound, as shown in Fig. 10.
There is a problem that the order of 11 is changed and it is not possible to wind according to the design instruction, and the deviation state of the winding 11 of each deflection coil that is mass-produced also varies from product to product, and the deflection magnetic field is reduced. There was a problem that it could not be controlled accurately. Further, since the mass-produced products vary, there is a problem that the yield is reduced, and there is a problem that the conventional winding method cannot cope with the cost. Even with this conventional method, if the width of the coil winding groove is made narrower, the deviation or deviation of the winding 11 can be reduced and the design instruction can be approached. In this case, however, the ratio L / R of the inductance L and the resistance R is reduced. Becomes smaller and the coil performance is degraded.

た。By the way, the saddle type bobbin for the deflection coil has coil winding grooves 5 in the crossover portions 18 and 19 of the coils on the head side and the tail side as shown in FIG. 8, for example. The height of the collar 3B inside the groove 5 is set higher than the height of the collar 3A outside. When a multifilamentary parallel conductor 15 is wound around the coil winding groove 5 of the bobbin 2 using a conventional winding machine for winding a single wire (not shown), the nozzle tip of the winding machine moves from the coil winding groove 5 to the coil winding groove 5. Since the multi-core parallel conductors 15 are twisted and wound by the connecting wire portions 18 and 19, and may be disengaged from the coil winding groove 5 because they are arranged far apart. Therefore, the applicants have proposed that the multicore parallel conductor 15
Using the winding machine shown in FIG. 3 which has a structure capable of shortening the distance between the tip of the nozzle and the coil winding groove 5, the multi-core parallel conductor 15 is stably inserted into the coil winding groove 5 and wound. Proposed.

により多心平行導線をスムーズに巻くことができる。Next, a work for manufacturing a saddle type deflection coil using this winding device will be described with reference to FIGS. 4 and 5. First, as shown in FIG. 4A, the bobbin 2 moves in the direction of the arrow, and at the same time, the nozzle 30 moves in the X-axis direction so as to face the inner peripheral surface of the bobbin at a predetermined interval. Thereby, the multi-core parallel conductor 15 is wound in the groove of the right inner peripheral wall surface 45 of the bobbin 2. When the nozzle 30 faces the upper end side of the bobbin 2 on the head side, as shown in FIG. 4B, the nozzle 30 is rotated from the a position to the b position to the c position along the arrow. At this time, when the nozzle 30 is once inflated to a position beyond the brim 3B and then returned to the c position and the multicore parallel conductor 15 is wound, it is smoothly wound. Next, set the bobbin 2 90 ° about the X axis.
By rotating the bobbin 2 in the counterclockwise direction by 180 ° about the X axis of the Z 1 point in the state shown in (c) of the figure by rotating clockwise, the state of (d) of the figure is obtained. Then, the multi-core parallel conductor 15 is wound around the connecting wire portion on the head side of the bobbin 2. Then, the bobbin 2 is rotated clockwise about the X axis by 90 °, and the state shown in FIG. Next, the nozzle 30 is rotated from the position c through the position d to the position a along the arrow. In this case, the multicore parallel conductor wire can be smoothly wound by temporarily inflating the nozzle 30 from the c position to the flange 3B side and then rotating it to the a position.

かれる。Next, in this state, the bobbin 2 is moved downward along the Z-axis, and at the same time, the nozzle 30 is opposed to the inner peripheral surface of the bobbin 2 at a constant distance from the X-axis. By moving to the left, the multi-core parallel conductor 15 is wound in the groove on the opposite side of the bobbin 2. When the center of the groove of the crossover part on the tail side of the bobbin 2 is lowered to a position facing the nozzle 30, the nozzle 30 is moved from the position a to the position b as shown in FIG.
After moving through the position to the c position along the arrow, the nozzle 30 also rotates once to the position beyond the collar 3B, inflates the multicore parallel conductor 15, and then returns to the c position. next,
By rotating the bobbin 2 clockwise by 90 ° with respect to the X axis, the state shown in FIG. 5B is obtained. In this state, the bobbin 2 is rotated 180 ° counterclockwise with respect to the Z-axis to bring it to the state shown in FIG. 5C, so that the crossover portion on the tail side is wound.

る。Next, the bobbin 2 is rotated clockwise by 90 ° about the X axis to the state shown in FIG. 5D, and in this state,
By once rotating the nozzle 30 in the opposite direction to a position beyond the collar 3B, inflating the multi-core parallel conductor 15, and then rotating the nozzle 30 from the c position to the d position to the a position along the arrow, (A), the multi-core parallel conductor 15 is continuously wound in each groove of the bobbin 2 by repeating the above operation, and a saddle type deflection coil is formed.

生し易いという問題があった。However, if the inner collar 3B of the crossover portion on the head side and the tail side of the bobbin 2 is formed to be higher than the outer collar 3A, the nozzle 30 extends from the inner peripheral surface in the longitudinal direction of the bobbin. When moving to the crossover portion, the nozzle 30 is rotated along the arrow from the position a to the position b to the position c as shown in FIG. 4B, but the nozzle 30 is moved over the inner collar 3B. It has been found that when the multi-core parallel conductor 15 is swung up and the multi-core parallel conductor 15 is inflated, then the nozzle 30 is returned to the c position and the multi-core parallel conductor 15 is wound, the winding is smoothly performed. There is a problem that the nozzle 30 easily hits the inner collar 3B, which makes the work difficult. The above phenomenon is shown in Figure 4.
(B) and (e) of FIG. 5 and (a) and (d) of FIG.
