DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connected coil winding machine used in a television receiver or the like, for example, for producing a correction coil for a deflection yoke.

[0002]

2. Description of the Related Art Conventionally, in the manufacture of a correction coil or the like used in a deflection yoke, a coil that needs to be electrically connected is connected at the time of winding in order to simplify wiring of the correction coil and the like. I have.

Hereinafter, a description will be given using a typical connection coil.

FIG. 8 is a perspective view of a primary connection coil, in which two formed bobbins 11a and 11b are connected to one first wire 18a.
Shows a primary connection coil which is connected and wound.

FIG. 9 is a perspective view of a two-layer connecting coil.
2 shows a two-layer connecting coil formed by winding the second wire 18b on the primary connecting coil.

[0006] The connecting coil shown in FIGS.
In that state, it may be used as a coil. In this way, the two coils are individually wound and connected at the time of winding instead of being connected by wiring at the time of assembling, so that a connected coil is used which reduces wiring work and connection failure. I have.

FIG. 10 is a perspective view of a connecting coil in which a connecting portion is twisted, and shows a connecting coil in which a connecting portion of the two-layer connecting coil in FIG. 8 is twisted.

FIG. 11 is an explanatory view of a conventional winding mechanism. One of the conventional methods of winding a connected coil is shown. Two forming bobbins 11a and 11b are connected by a connecting jig 27 and this is connected. The connection coil is wound by being fixed and rotated by one winding shaft. Reference numeral 28 in the drawing denotes a nozzle for feeding out a wire.

FIG. 12 is an explanatory view of a conventional winding mechanism, showing another conventional winding method of a connected coil, in which two formed bobbins 11a and 11b are coaxially provided with different windings. It is fixed to a shaft, the two winding shafts are connected by a spline shaft 30, and is rotated synchronously by one motor 29, thereby winding a connected coil. 31a in the figure,
31b, 31c and 31d are pulleys, and 32a and 32b are belts.

FIG. 13 is an explanatory view of another conventional winding mechanism, and shows one of the other conventional winding methods of a connected coil. In forming, two forming bobbins 33a and 33b are connected by a connecting portion 34. It is formed by connecting and integrating, and after the winding is completed, separated to form a connecting coil.

[0011]

The connection coil manufactured by the winding machine shown in FIG. 11 has the following structural problems. That is, the two formed bobbins 11a,
Since the connecting jig 27 is used for the connecting portion 11b, it is necessary to replace the connecting jig 27 when changing the length of the connecting portion, and the connecting jig 27 according to the type of the connecting coil is required. Also, the mounting of the connecting jig 27 is complicated, and it is difficult to automate the mounting of the forming bobbins 11a and 11b and the removal of the product coil. Further, when a plurality of electrically insulated wires are wound, it is not possible to add a twist to the connecting portion to prevent the wires from being separated.

Further, the winding machine constructed as shown in FIG. 12 has the following structural problem. That is, since the winding shafts on the same axis are mechanically connected and driven in a completely synchronized manner by one motor, when a plurality of electrically insulated wires are used, it is not possible to add a twist for preventing the connection portion from becoming loose. .

Further, the connecting coil wound on the formed bobbin as shown in FIG. 13 has the following problem in structure. That is, since the two bobbins are integrally formed by coupling, a change in the molding die is required to change the specification, and it is possible to cope only with mass production. In addition, it is necessary to separate the formed bobbin after winding.

[0014] As described above, in the conventional winding machine, when the primary winding is performed and the double-layer winding coil on which the secondary winding is performed is produced, the bobbin is once removed and the winding is performed by another winding machine. However, it was difficult to automate it. Also, there is no automatic way to twist the joint to prevent loosening.
It was done manually.

The present invention has been made to solve the above problems, and provides a connected coil winding machine which improves the productivity by automating the torsion processing for preventing the winding of the connected coil and the connecting portion from being separated. The purpose is to:

[0016]

In order to achieve the above object, the present invention provides a structure in which two winding shafts which are arranged opposite to each other at a distance are driven by separate motors without being mechanically connected, and In addition, not only the two winding shafts can be completely synchronized and rotated in the same direction, but also can be operated in different directions and at different speeds while being synchronized.

According to the present invention, the winding of the two coils can be facilitated, and processing such as twisting of the connection between the two coils can be made possible.

[0018]

When performing the one-side winding, the winding shaft 13e1 also rotates synchronously so that the intermediate connecting wire is not cut off. Similarly, secondary winding is performed using the nozzle 15b1. At this time,
In this state, as shown in FIG. 9, the connecting line portion is disjointed, which causes a problem in an assembling work in a later process. Therefore, as shown in FIG. 10, a twist is applied to the connecting portion in order to prevent separation. In this winding machine, the winding shaft 13d1 and the winding shaft 13e1 are configured to be driven by different motors, respectively, so that the connecting portion can be twisted.

As shown in FIG. 6, the connecting coil is removed by pushing out the second forming bobbin 11b held by the winding shaft 13e1 with the second nozzle bar 10b. Further, as shown in FIG.
The first forming bobbin 11a held at 1 is pushed out and removed. Thereafter, the connecting coil falls and is taken out by the product take-out conveyor 9 (see FIG. 1). As described above, the time is shortened by taking out the product coil by the dropping method.

[0038]

As is apparent from the above description, the present invention cannot be manufactured by a conventional single winding machine, and a connecting coil having a twisted connecting portion which requires manual operation. By automating the winding of, it is possible to realize a great rationalization. In addition, since it is possible to easily change the product specifications such as the length of the connecting portion and the number of windings, it is possible to greatly reduce the time required for switching between models. In addition, since the twisting of the connecting portion, which has been manually performed in the past, is automated, a connected coil winding machine having high productivity can be provided.
