Patent Application No. 147989, filed on August 26, 1981.

The company has filed a patent application for a cylindrical winding body in Japanese Patent Application No. 147990/1983. This cylindrical winding body is a cup-shaped body with a bottom), and the wire is directly wound around a cylindrical jig serving as a wire-wound body to form a winding element in the shape of a cup-shaped cylinder with a bottom. It is constructed by forming a wire body and removing the wound wire body from this cylindrical jig. The cylindrical jig used as the wire-wound body has a shoulder on which the wire is wound at its axial end. A bottomed cup cylindrical winding body with a small axis length! l! ! When constructing a structure, when securing the strands to the shoulder,
What is the invention disclosed earlier?

It is difficult to align and lock the wires around the circumference and form an orderly string-shaped stranded wire band on the shoulder, and the circumferential surface of the cylindrical jig as the wire-wound body. Also, there is a problem in that the thickness in the radial direction increases, making it difficult to manufacture a thin bottomed cup cylindrical winding body.

Therefore, a method for manufacturing a cup-shaped cylindrical winding body with a bottom and an apparatus for manufacturing the same can manufacture a cylindrical cup-shaped winding body with a bottom that is wound in alignment even when the axial length is small relative to the diameter. is being developed.

In that case, a bottomed cup cylindrical winding body whose axial length is smaller than the diameter of one part is used as a flat motor armature wire ring, and two
When used in a pole or four-pole motor, the wire band that is secured to the shoulder should be shaped like a curved line, and the edge of the shoulder should be shaped as shown in Fig. 5 (α). As shown in Fig. 5(b), the center of rotation of the bobbin as a wire-wound body is moved close to the center of rotation of the bobbin as shown in Fig. 5(b). Then, the flat motor 'iI! When used as a machine coil wheel, the magnetic force generated in the wire band portion secured to the shoulder portion is utilized, which is desirable for improving the generated torque.

However, when manufacturing this bottomed cup cylindrical winding body, if the tension band portion to which the shoulder portion ζ is fixed is curved, tension is applied to the strand wire during the winding operation. Is the force directed toward the axis of each rotation for each strand in the strand band to hang? Kojiri Narrow Neck L
Because of the large tendency to wrap around each other, each of the strands constituting the strand band overlaps each other irregularly near the rotation axis, creating a mountain height of t in the direction of the rotation axis, resulting in a bottomed wire with a flattened waste portion. It is difficult to manufacture a cup-shaped embroidered body.

The present invention has been made in view of the above-mentioned problems, and its purpose is to unify the flattened shape even in a bottomed cup cylindrical winding body in which the wire band is curved in the 1M section. An object of the present invention is to provide a method for manufacturing a bottomed cup cylindrical winding body that can be used to manufacture products.

A method of manufacturing a bottomed cup tube winding body according to the present invention will be explained below with reference to the drawings.

FIG. 1 shows a longitudinal cross-sectional view of a short cylindrical bobbin as a wire wound body used in a bottomed cup cylindrical winding body according to the present invention, and 1 is a short cylindrical bobbin. , this bobbin 1 has a shoulder portion 2 and an open end surface 3, and a rotating shaft 4 is integrally formed on the bobbin 1 by a molding method,
This bobbin 1 is also made by hot pressing a fill or sheet to make the air cap smaller. A riser 5 is provided on the bobbin 1.

This riser 5 is a part of the commutator and is used for tapping and soldering.

The commutator further extends in the axial direction toward the open end surface 6, and the bobbin 1 is mounted on a cylindrical jig 61 as shown in FIG. This cylindrical jig 6 is composed of an inner tube 7 and an outer tube 8 that can move in the direction of the arrow.

An insertion hole 9 for the rotating shaft 4 is formed in the inner cylinder 7 . The outer cylinder 8 rotates with the inner cylinder 7, and the axis of rotation is aligned with the fine point of the cylindrical jig 6 above the cylindrical jig 6, as shown in FIGS. 3 and 4. A shaft 10 is provided, and an alignment plate 11 and a guide plate 12 are attached to the shaft 10, which apply line pressure in the plane direction to align the lines. It is possible to arrange not only single rows but also double rows. These alignment plates 11 and guide plates 12 are connected to the shaft 1
It is configured to be inclined with respect to 0. This alignment plate 11
For two poles, the shape is slightly larger than a semicircle, and for four poles, its shape is preferably thicker than a five-part, four-circle shape.Also, the size of the guide plate 12 is the same as the shape of the alignment plate 11. or even larger.

As shown in FIG. 5, three elastic rollers 14, 15, 16 are pressed against the circumferential surface 15 of the bobbin 1, 17, 1B,

, 15 has the shape of a circle φ11, and in Fig. 4 ζ,
14α indicates the tapered surface of the elastic roller 14. The elastic roller 16 has a cylindrical shape, and the strands 20 are aligned and locked on the 1M section 2 and the opening end surface 3.

The elastic rollers 14, 15.1+5 function to align and lock the windings of the strands 20, press against each other, and rotate to press and flatten the already wound wire bands. alignment 11
and the guide 12 have a half-moon shape as shown in FIG. At the same time, the 1M section 2 is engaged with the surface of the alignment plate 11 by pressure contact, and the opening end surface 3 is engaged with the elastic roller 16, and this process is repeated several times. On the side, as shown by symbols ■, ■, ■, and ■1■, the alignment plates 18 are locked.

The strands 21 formed by the alignment plate 11 are aligned, and the strands 20 constituting the strands 21 are prevented from overlapping each other. On the side of the opening end surface 3, as shown in FIG. 4, they are aligned in the space between the a-ra surface, the bobbin edge, and the outer cylindrical surface or the space of the already wound wire band on the outer cylindrical surface to form a wire band. This locking portion has a reduced increase in thickness in the radial direction.

After straining in this manner to form the strand band 22.

As shown in FIG. 5, the shaft 10 is rotated in the direction of the arrow with respect to the bobbin 1. The rollers 17, 18, and 19 remain as they are, and while only the alignment plate 11 rotates once, the alignment plate 1
The wire band portion 21 that is locked to the alignment plate 1 comes off the edge 23 of the alignment plate 11 on the side closer to the shoulder 2 and comes into contact with the shoulder surface of the bobbin, and after one rotation of the alignment plate 11, the shoulder The end edge 24 on the side far from 2 is located directly above the strand band portion 21 on the bobbin surface. Therefore, as shown in FIG. 4, the lead wire 25 for tapping is pulled out.

After completing the wire strip on the entire surface of the bobbin, solder the wire to the riser along the wire strip surface.Also, for brushless motors, this 11-person lead wire will be used.1. (Ru.

Thereafter, the operation of moving the cylindrical jig 6 and the bobbin 3 relative to the 44i11o and the elastic rollers 14, 15, and 16 by an angle of 1 is repeated, so that a plurality of wire bands 22 are formed around the entire circumference of the bobbin 1. The bobbin 1 is moved in the direction of the arrow in the inner cylinder shown in FIG. 2 along with the rollers 1i1f117, 18, 19 and the alignment plate shaft 10 to quickly remove the inner cylinder. 1 x 1 elastic roller 14, 15, 16 and bobbin 13 are fixed and alignment plate 11. When the guide plate 12 is rotated 660 degrees to remove the strand Vi from the alignment plate 11 and lock it to the shoulder 2, the strand band is pressed against the shoulder 21 by the alignment plate 11i. .

FIG. 6 shows a cylindrical winding body 26 manufactured in this way.
This figure shows the schematic configuration of the . Figure 7 shows an example of a flat two-pole motor using this bottomed cup cylindrical winding body. When using a bottomed cup cylindrical winding body for this two-pole motor, it is necessary to configure the wire band to be curved and locked to the shoulder so that it has approximately the same length as the diameter of the bobbin. This is desirable from the viewpoint of maximizing the torque.

Since the present invention is a method for manufacturing a cylindrical winding body as described above, even if the wire band portion that is secured to the shoulder portion of the bobbin is in a curved state, winding can be performed in an orderly manner. This has the effect that it is possible to provide a bottomed cup tube winding body formed of aligned winding bands having a flat M section.
