Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device and a winding method. More specifically, the versatility of a winding device that winds a plurality of coils with different axes on a single core,
The present invention relates to improvements in winding efficiency and the like, and a winding method using this winding device.

[0002]

2. Description of the Related Art Conventionally, as a winding device, for example, one described in Japanese Patent Publication No. 57-42207 is known.

This conventional winding apparatus has a wire rod winding side provided with a spindle for rotatably supporting a core (bobbin) around which the wire rod is wound, and a wire rod provided with a flyer for swirling and supplying the wire rod to the core. It consists of the supply side.

In this conventional winding device, when the coil end wire of the wire rod is wound on the core protrusion, the rotation of the spindle is stopped and the flyer is rotated to wind the flyer, and the wire rod is wound around the main body of the core. When winding, the flyer is stopped and the spindle is rotated to wind the spindle. Therefore, by switching between the flyer winding and the spindle winding, it is possible to wind a plurality of windings having different axes with respect to a single core while supporting the core on the spindle. As a result, it is expected that the work of attaching and detaching the core for each winding of each coil is omitted and the winding efficiency is increased.

[0005]

In the above-mentioned conventional winding device, the axis of the coil winding is selected by switching between the flyer winding and the spindle winding, and is on the same line or orthogonal to the rotation axis of the spindle. Since only the coil of the axial line can be wound, there is a problem that versatility is low.
Further, since the flyer must be stopped when the spindle is wound, there is a problem that the winding efficiency becomes low due to the resistance between the flyer which is not rotating and the wire.

The present invention has been made in consideration of the above problems, and provides a winding apparatus having high versatility and high winding efficiency, and using this winding apparatus, high winding efficiency is provided. An object of the present invention is to provide a winding method for winding.

[0007]

In order to solve the above-mentioned problems, a winding device according to the present invention comprises a wire rod winding side provided with a spindle for rotatably supporting a core around which a wire rod is wound,
In a winding device comprising a wire rod supply side provided with a flyer for swirling and supplying a wire rod to a core, a moving means is provided on one or both of the wire rod winding side and the wire rod supplying side, and the wire rod winding side and the wire rod supplying side are provided relative to each other. A means characterized in that the angle formed by the rotation axis of the spindle and flyer can be changed by movement is adopted.

In order to solve the above-mentioned problems, the winding method according to the present invention includes a wire rod winding side provided with a spindle for rotatably supporting a core around which the wire rod is wound, and a wire rod on the core. A winding device consisting of a wire rod supply side equipped with a flyer for swirling and feeding and a moving means provided on one or both of the wire rod winding side and the wire rod supply side is used, and the rotation axes of the spindle and flyer are set on the same line. Then, the spindle and the flyer are rotated in opposite directions to wind the wire on the core.

[0009]

According to the above-mentioned means, the angle formed by the rotating shafts of the spindle and the flyer can be changed by operating the moving means. Changing the angle formed by the rotation axes of the spindle and flyer changes the axis of the coil wound around the core. When the spindle and flyer rotation axes are set on the same line, when the spindle and flyer are rotated in opposite directions, the wire is wound around the core at high speed.

The wire rod S supplied from a supply unit (not shown) is inserted into the flyer shaft 22a and the flyer nozzle 22c of the flyer 22.

On this wire feed side 2, a moving means 4 for moving the beam 21 forward and backward, left and right and up and down and rotating 90 degrees.
Is attached. This moving means 4 is a servo motor,
It is a combination of a plurality of actuators such as air cylinders, and is automatically controlled in the operation described later.

In this embodiment, at the time of operation and use, first, the core B is attached to the spindle 12. Next, in FIG.
As shown in FIG. 3, the moving means 3 and 4 are driven to set the spindle 12 and the flyer 22 so that the rotation axes X and Y are horizontal and on the same line. At this time, one or both of the moving means 3 and 4 are driven so that the flyer nozzle 22c of the flyer 22 is positioned between the extensions of the overhanging plates Bc and Bd of the core B so that the spindle 12 and the flyer 22 are positioned.
Adjust the interval of. Further, the wire rod S is attached to the flyer nozzle 22.
Draw up to c and perform necessary terminal processing.

Then, the spindle 12 and the flyer 22 are rotated in opposite directions.

The rotation of the spindle 12 and the flyer 22 in the opposite directions accelerates the winding speed of the wire rod S to wind the main coil 7a around the body portion Bb of the core B at an extremely high speed. At this time, one or both of the moving means 3 and 4 are driven to move the spindle 12 and the flyer 22 closer to or away from each other, and the winding position of the wire S around the body portion Bb of the core B is sequentially moved to perform winding alignment.
