And such a continuous coil element 11
For example, as shown in FIG. 10, a plurality of flat winding jigs 21 through which a shaft 19 is inserted at the center are sequentially wound with a coil wire e from one side, and the coil element 11 is wound around each winding jig 21. Are formed by continuously adhering coil wires e forming the coil element 11 to each other by energizing the continuous coil element 11 after the
Thereafter, the coil element 11 is sequentially removed from the winding jig 21, and the removed coil element 11 is fused on the hook 17 of the commutator 15, and the commutator
It is manufactured by resin-molding by arranging the coil elements 11 so as to partially overlap each other with the coil elements 11 lying on the outside of 15.

[Problems to be solved by the invention]

However, in such a conventional method of manufacturing an amateur for a flat motor, as shown in FIG.
It is very difficult to get into the lower side of 11, and one side of the coil element 11 at the end of assembly is placed on the coil element 11 at the beginning of assembly,
There was a problem that the balance was very bad.

In addition, since the coil elements 11 are formed continuously, it is very difficult to automate the arrangement of the coil elements 11 outside the commutator 15 and must rely on manual work, requiring a large number of manufacturing steps. There was a problem of becoming.

The present invention has been made in order to solve such a conventional problem, and is to arrange a plurality of coil elements formed continuously by one coil wire on the outside of a commutator in a prompt and reliable manner. It is an object of the present invention to provide a method of arranging coils of an amateur for a flat motor that can be performed.

FIG. 6 shows details of a coil arranging device for arranging the coil elements 37. This coil arranging device is a housing jig for accommodating each coil element 37 in a state of being erected radially at a predetermined angle. A transfer jig 39 and an annular apparatus main body 300 disposed above the transfer jig 39.
And a rotation mechanism 310 for rotating the apparatus main body 300 by a predetermined angle.
And a gripping mechanism 320 that is arranged at a predetermined angle in the apparatus main body 300 and grips the coil element 37, and rotates in synchronization with the rotation of the rotation mechanism 310.

The gripping mechanism 320 has a movable claw 321 and a fixed claw 322, and the movable claw 321 is connected to a moving member 323 movable by a cylinder 330. The moving member 323 includes a piston 324 and a cylinder.
325, and a spring 326 is fed between them. Further, the cylinder 325 is rotatably mounted on the rotation shaft member 340, and is movable in the front-rear direction by a spring 341. Then, when the piston 324 is advanced by the cylinder 330, the spring 341 is moved.
Is weaker than the spring 326, the cylinder 325 can be advanced while the spring 341 is compressed.
When the cylinder 325 advances by a predetermined length, the stopper 327 provided on the outside comes into contact with the protruding piece 341 of the rotating shaft member 340, and stops its movement. Further, the force of the cylinder 330 is applied to the piston 3
When hung on 24, the spring 326 is compressed, and the movable claw 321 which is axially attached to the piston 324 via the pin 329,

In the above-described coil arrangement device, first, at a predetermined position of the device, a transfer jig 39 that accommodates the coil element 37 in a state of being erected radially so that the connection wire 35 of the coil element 37 is located on the center side is arranged. Is done.

Thereafter, each gripping mechanism 320 disposed at a predetermined angle on the annular apparatus main body 300 disposed above the transport jig 39.
Activate In each gripping mechanism 320, the cylinder 330 pushes the piston 324 toward the coil element 37. As a result, the spring 326 is compressed, and the stopper 327 is
The cylinder 323 is advanced until it comes into contact with 341. And
When the stopper 327 contacts the protruding piece 341, the spring
326 is compressed, and the movable claw 321 is
Move to the position shown by the two-dot chain line
Is gripped by the movable claw 321 and the fixed claw 322. Thereafter, the transport jig 39 descends and is removed from the apparatus. Next, the cylinder 311 of the rotation mechanism 310 is extended to rotate the apparatus main body 300 by a predetermined angle. Accordingly, the rotating shaft member 340 rotates while advancing the pin 343 through the notch 303, and the coil element 37 is simultaneously tilted in the same direction to be in a horizontal state. Thereafter, the assembling jig 60 is inserted into the position where the transport jig 39 was set, and then each of the coil elements 37 arranged in the horizontal direction is erected on the cylindrical portion 62 of the assembling jig 60. The mounting jig 60 is raised so as to be locked by the plurality of pins 61. Then, the gripping mechanism 320 pulls the cylinder 330 to open the movable claw 321 and the moving member 323 is returned to the original position by the spring 326. Thereafter, the cylinder 311 of the rotating mechanism 310 returns to the original position. After a while
