Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for, for example, a coreless morph cup-shaped rotor.

Conventionally, this type of device has a rotating shaft 1 as shown in FIG.
A pair of guide holders 3, 3, which revolve around the outer periphery of the winding frame 2, are provided opposite to each other with the winding frame 2 in between.

The guide holders 3, 3 are fixedly provided with guide pieces 4, 4 which extend perpendicularly to the winding frame 2 and whose free ends are formed at an acute angle, or the guide pieces 4, 4 are fixed to the winding frame 2. The frame 2 has elasticity in the circumferential direction.

The tips of the guide pieces 4, 4 are held in contact with the side wall of the winding frame 2, and the winding 5 is held and bent by the tips of the guide pieces 4, 4 and the side wall of the winding frame 2.

Further, above the winding frame 2, there is a swing frame 6 which reciprocates once every time the winding frame 2 and guide holders 3, 3 rotate once to swing the winding 5.
is provided.

In order to wind the wire in this conventional device, first, both the winding frame 2 and the guide holders 3, 3 make one revolution, and the swing frame 6 reciprocates once, and the winding 5 moves through the guide pieces 4, 3. The wire is wound around the winding frame 2 while forming a triangular wave with the tip of the wire as the apex.

After both the winding frame 2 and the guide holders 3, 3 have rotated once, hot air is radiated onto the wound wire body 6 to fix the adjacent windings 5, 5 of the winding body 6.

After that, when only the guide holders 3, 3 are further rotated by one pitch of the winding, since the guide pieces 4, 4 have elasticity, the guide pieces 4, 4 are elastically deformed and the fixed It climbs over the apex of the winding body 6 and moves in the circumferential direction of the winding frame 2 by the width of the pitch.

This operation will be repeated periodically from now on, but since it is necessary to make the guide pieces 4, 4 elastic as described above, when winding around the winding frame 2, there will be a gap between the winding frame 2 and the tips of the guide pieces 4, 4. There is a possibility that the winding 5 may fall off while elastically deforming the guide pieces 4, 4, which is a particular problem when the diameter of the winding 5 is small.

In addition, since the tips of the guide pieces 4, 4 must be in contact with the side wall of the winding frame 2, only one layer can be wound around the winding frame 2.
It was impossible to make multiple layers.

□P The present invention eliminates such difficulties and enables multilayer winding without the winding 5 falling off from the guide pieces 4, 4 during the winding operation. Examples thereof will be described below. The details will be explained according to the drawings.

In FIG. 4, reference numeral 10 denotes a cylindrical winding frame fitted to the rotation shafts 11, 11 at the attachment/detachment position, and the rotation wheels 11, 11

It is connected to the rotation shaft 17 of.

A guide holder 12 is provided around the disk 13.13 and extends in the axial direction of the winding frames 10, 10 at right angles to the disk 13.13.
．． 12 are arranged symmetrically opposite to each other with the center of the winding frame 10 as a point of symmetry.

The guide holder 12.degree. 12 is rotatably attached to the disks 13, 13 as shown in FIG.

At the tip of the guide holder 12.12, there is a guide frame 18.18' made of a wire that extends perpendicularly to the axis of the winding frame 10 and whose free end is curved along the peripheral side wall of the winding frame 10. will be permanently installed.

It is preferable that the guide frames 18, 18' become narrower toward the tips and have smooth surfaces, and as shown in FIG. As a guide for the winding 28, it is preferable that the windings 28 be connected in series.

Above the winding frame 10, there is a swing frame 21 for swinging the winding 28 in the direction of the axis of the winding frame 10, in synchronization with the rotation of the disk 13.13, that is, the rotation of the guide frame 18.18'. The swing frame 21 is provided with a through hole 22 at the tip thereof to guide the winding 28 therethrough.

Furthermore, above the swinging frame 21, a porous body such as a sponge body 23 impregnated with an organic solvent such as alcohol for dissolving the resin film on the surface of the winding wire 28 is provided. It is configured such that the line 28 passes through it.

A pipe 24 is provided below the winding frame 10 for heating the winding body 32 wound around the winding frame 10 and radiating hot air for welding the resin film on the surface of the winding body 32.

A timing pulley 25.25 is fitted and fixed on the rotary shaft 11.11 outside the disk 13.13, and the timing pulley 25.25 is connected to the timing bells 1-26.26 and other timing boots. It is connected via IJ 27 and 27 to a rotation shaft 29 of a pulse motor (not shown) different from the one described above.

The above is the configuration of one embodiment of the present invention, and the winding process will be described in detail below with reference to the drawings of FIGS. 4 and 5 to 10.

First, one end of the winding wire 28 is fixed to a part of the winding frame 10, and the rear guide holding rod 12 and the rotating shafts 11, 11 are rotated.

At this time, each guide holding rod 12, 12 and each rotating shaft 1.1, 1
1 are mutually timing belts 15, 15, 26, 2
Since they are connected at 6, they each rotate integrally.

As the guide holding frames 12, 12 rotate, the swing frame 21 moves synchronously in the axial direction of the winding frame 10, and the winding frame 10 is fitted onto the rotation shaft 11, "1"'1. Therefore, the winding 2B rotates together with the rotating shaft 11° 11, and the winding 2B slides into the space between the curved portion 19 of one guide frame 18 and the winding frame 10 (Fig. 5).
When the guide holding frames 12, 12 and the winding frame 10 further rotate and the swing frame 21 moves, the winding 28 is wound and bent around the guide frame 18 (FIG. 6).

When the winding frame 10 and the guide holding frames 12, 12 further rotate,
The winding 28 is connected to the curved portion 19' of the guide frame 18' and the winding frame 1.
0 (Fig. 7), and then wound around the guide frame 18' (Fig. 8). When the guide frame 12.12 and the winding frame 10 further rotate, the winding 28 returns to its original state. Return to position and finish the first winding.

Next, only the guide holding frame 12.degree. 12 continues to rotate by one pitch of the winding, and then the winding operation is repeated.

After repeating the winding operation for the required number of windings, as shown in FIG.
The rotation continues until the curved portion 19.19' of 8° 18' passes through the bent portion of the winding body 32.

After the curved portions 19 and 19' are completely removed from the curved portions of the winding body 32, the guide holders 12 and 12 move the guide frames 18 and 18' away from the winding frame 10, respectively, as shown in FIG. Rotate using rollers or other means.

Next, the winding 28 is cut at a position directly above the winding frame 10, and when the rotating shafts 11 and 11 move in the direction away from each other, the winding frame 10
is removed from the rotation shafts 11, 11.

Finally, the wound body 32, ie, the cup-shaped rotor, is pulled out from the winding frame 10 in the axial direction to complete the winding process.

It should be noted that if the winding wire 28 is thin (0.2 mm in diameter) or less or if the total number of turns is relatively small, this will not be much of a problem.
If the wire diameter is thick or the total number of turns is large, the winding body 3 after winding
Since the outer shape of the winding frame 2 is drum-shaped, this problem can be solved by cutting out notches 29, 29 in the part of the winding frame 10 corresponding to the curved part 19 of the guide frame 18, as shown in FIG. can.

Furthermore, instead of emitting hot air to fix the wound wire body 32, it is also considered to insert a heating element 30, 30 into the tip of the rotating shafts 11, 11, as shown in FIG. It will be done.

Further, as shown in FIG. 15, the guide frames 18, 18' are
The guide and holding frames 12, 12 may be formed of a plate-shaped body having a width in the axial direction. In this case, if the tip of the guide frame 18.18' is formed at an acute angle, the guide frame 18.1B' Winding body 3
