Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view showing a winding device according to an embodiment of the present invention. FIG. 2 is a rear view showing the same winding device.

As shown in the drawing, a spindle 2 penetrates through a support hole 1A of a spindle support portion 1 of the winding device, and is rotatably supported via bearings 3a and 3b. The spindle 2 is driven to rotate by rotation driving means (not shown).

The spindle 2 is a cylindrical member, and a former support shaft 5 is rotatably accommodated coaxially in a hollow portion thereof through bearings 4a and 4b. Further, the front end side of the spindle 2 is a flyer portion 2A whose diameter is widened like a trumpet. Inside the flyer portion 2A, a center former 6 supported by a front end of a former support shaft 5 is disposed.

A wire guide cylinder 7 made of a non-magnetic material is fixed to the spindle 2 in parallel with its rotation axis. A wire 8 from a wire source (not shown) is introduced into the wire guide tube, and the wire 8 is fed out from a guide (wire feeding portion) 9 fixed to a predetermined position at the tip of the flyer 2A, and the center former 6 is inclined. It is guided by the surface, slides into the throttle of the rotor 10 of the armature, and is wound around the rotor 10 as the core with the rotation of the spindle 2.

The rotor 10 is gripped by gripping means (not shown) and is sequentially indexed in the direction of rotation by an indexing device (not shown), so that windings are sequentially wound on each throttle of the rotor 10. ing.

A plate-shaped magnet support 11 extends from the spindle support 1 and is arranged behind the base end of the spindle 2. The magnet support 11 has a circular opening 11 concentric with the rotation axis of the spindle 2 and the former support shaft 5.
A is formed. A magnet mounting portion 12 is fixed to the base end of the former support shaft 5, and the magnet mounting portion 12 is disposed exactly on the opening 11A.

The proximal end of the wire guide tube 7 extending from the proximal end of the spindle 2 passes through a gap between the inner periphery of the opening 11A and the outer periphery of the magnet mounting portion 12 and is located behind the magnet support portion 11. , And the wire 8 is introduced therein. When the spindle 2 rotates, the base end side of the wire guide tube 7 revolves along an annular gap between the inner periphery of the opening 11A and the outer periphery of the magnet mounting portion 12.

A first magnet 13 (for example, a permanent magnet) is mounted on the magnet support portion 11, and a second magnet 1 is mounted on the magnet mounting portion 12.
4 (for example, permanent magnets) are respectively embedded.
The N pole 13a and the S pole 13 of the magnet 13 of the magnet support 11
“b” is disposed at a predetermined position on the inner peripheral edge of the opening 11A, approximately 180 degrees apart. Also, the N pole 1 of the magnet 14 of the magnet mounting portion 12
The 4 a and the S pole 14 b are arranged at a distance of approximately 180 degrees on the outer periphery of the magnet mounting portion 12. With such a configuration, an attractive force acts between the S pole 13b of the magnet 13 and the N pole 14a of the magnet 14, and an attractive force acts between the N pole 13a of the magnet 13 and the S pole 14b of the magnet 14. Therefore, the rotation position of the former supporting shaft 5 is determined by the N pole 14 a and the S pole 14 b of the magnet 14 of the magnet mounting portion 12 and the S pole 13 b and the N pole 1 of the magnet 13.
It becomes stable at the position facing 3a.

A concentric disk 15 centered on the rotation axis is fixed to the spindle 2. The rotation of the disk 15 is detected by a rotation sensor 16 fixed to the spindle support 1. The rotation speed of the spindle 2 detected by the rotation sensor 16 is feedback-controlled by control means (not shown).

Next, the operation will be described.

When the spindle 2 is rotated by the driving means during winding by the winding device, the guide 9 at the tip of the flyer portion 2A revolves around the rotor 10 of the armature. The wire 8 guided from the wire source via the wire guide cylinder 7 is fed out of the guide 9, guided to slide on the slope of the center former 6, reaches the throttle of the rotor 10, and revolves along with the revolution of the guide 9. It is wound around.
In this case, the former supporting shaft 5 that supports the center former 2 is in a stationary state at a predetermined rotation angle due to the magnetic force of the magnet 14 of the base magnet mounting part 12 and the magnet 13 of the stationary magnet supporting part 11. Is kept.

As described above, according to the present invention, the spindle 2
Fix the center former 2 against the rotation of the magnet 1
Since it is performed by the magnetic force of 3 and 14, there is no need for a mechanism such as a gear for fixing the center former 2. Since the wire guide tube 7 for guiding the wire 8 extends from the base end of the spindle 2 through the gap between the magnets 13 and 14, the wire can be supplied from the extended base end. On the other hand, during the rotation of the spindle 2, since it moves in the annular gap between the magnets 13 and 14 for fixing the center former 2, it does not interfere with the fixing mechanism of the center former 2. Therefore, a rational mechanism for fixing the center former 2 can be configured very simply with a small number of parts, and the cost of manufacturing the winding device can be reduced.

Since the wire guide tube 7 is made of a non-magnetic material, the magnetic force of the magnets 13 and 14 does not act on the spindle 2 via the wire guide tube 7,
It does not affect the rotation of the wheel.

The magnetic poles of the magnets 13 and 14 are arranged at positions 180 degrees apart from the inner circumference of the opening 11A and the outer circumference of the magnet mounting portion 12, respectively. Fixation is performed stably.

Further, along the outer periphery of the magnet mounting portion 12,
As the second magnets, the same number of magnets 22 as the magnets 21 are provided radially. In this case, the magnetic pole of each magnet 22 is
Arranged at predetermined intervals along the outer periphery of the magnet mounting portion 12,
It is made to face the magnetic pole of the magnet 21 just across the annular gap. Then, the magnetic poles of the magnets 22 arranged along the outer periphery of the magnet mounting portion 12 such that the magnetic poles of the magnets 21 and 22 facing each other are exactly opposite to each other. It is to be.

With this configuration, in the present embodiment, a plurality of magnets 2 provided on the entire area on both sides of the annular gap portion are provided.
Since the magnetic force for fixing the former support shaft 5 can be obtained by the first and the second 22, a large magnetic force can be obtained, and the stability of fixing the former support shaft 5 can be improved.

As described above, in the present invention, the first and second magnets can be composed of a plurality of magnets. In the present invention, the arrangement of the first and second magnets is not particularly limited, and the first and second magnets can be arranged in various forms.

The same number of protrusions (magnetic force acting portions) 32 as the magnets 41 are provided. As a result, the rotation of the former support shaft 5 is fixed at a position where the magnet 41 of the magnet mounting portion 12 faces the front of the protrusion 42.

As described above, according to the present invention, the magnet 31 or 41 is provided only on one of the magnet support portion 11 and the magnet mounting portion 12, and the magnetic force acting portion 32 or 42 on which the magnetic force of the magnet 31 or 42 acts is provided on the other. Such a form can also be taken.

In each of the above embodiments, the magnet 1
