巻き戻りを防ぐようにしている。In this device, a conductor is first wound around the outer circumference of one end of an insulating tube attached to a rotatably driven mandrel from the inner circumferential side to the outer circumferential side to form one disc-shaped unit coil. Next, the conductor is wound next to it from the outer circumference to the inner circumference to form a unit coil, which is repeated in the axial direction of the insulating tube, thereby forming the continuously wound unit coil into multiple stages. It was designed so that it could be formed. When winding a conductor in this device from the outer circumferential side to the inner circumferential side, a ring with an inner diameter equal to the outer diameter of the unit coil is provided, and the conductor is pressed against the inner circumferential surface of the ring. The feed speed of the conductor is controlled in accordance with changes in the coil winding diameter, and the conductor being fed is sequentially pushed into the inner peripheral surface of the coil by a unidirectional rotating roller that is in contact with the side surface of the coil, and the coil is prevented from unwinding. ing.

A mandrel is provided to create a coil by repeatedly winding the coil in the same direction, and a movable housing is provided so as to be movable along the axial direction of the mandrel. A rotating ring that receives the outermost side is provided, a support body is provided that rotates synchronously with the rotating ring, and the inner circumferential surface of the coil that is being wound from the inner circumferential surface of the rotating ring toward the inner circumferential side is pressed. A plurality of clamp members each having a suppressing portion are movably provided on the support body, and a biasing means is provided for biasing the clamp members in a direction in which the suppressing members come into pressure contact with the inner circumferential surface of the coil.

The support ring 31 and clamp member 28 of the mandrel 8
is rotated in the direction of arrow A at the same speed as . As the second support ring 31 rotates, one clamp member 4
1 reaches the starting end 48a of the cam 48, the clamp member 41 rides on the cam 48, and the pressing claw 43 separates from the inner circumference of the coil 18 as described above, and the clamp member 41 moves onto the cam 48. When it comes off the terminal end 48b,
The pressing claw 43 is brought into pressure contact with the inner periphery of the coil 18 again by the biasing force of the compression coil spring 45. In this case, the conductor 46 sent out from a supply device (not shown) is supplied into the movable housing 11 from a substantially central position of the escape groove 47 through a path as shown by the two-dot chain line in FIG.
It is curved so as to be introduced into the inner circumferential side of the coil 18 at a position corresponding to the middle of the terminal end 48b.

The main motor 4 is stopped as follows. After this, the feed motor 16 is driven to move the movable housing 11 to the standby position at the right end indicated by the two-dot chain line in FIG. Thereafter, the above-described operation is repeated to wind a predetermined number of coils around the insulating cylinder 9.

きる。As described above, according to the above configuration, when the coil 18 is formed by winding the conductor 46 on the inner circumferential surface of the rotating ring 30 from the outer circumferential side toward the inner circumferential side, the coil 18 being wound is Since the inner periphery of the conductor is pressed outward by the pressing claws 43 of the plurality of clamp members 41 provided on the second support ring 31 that rotates in synchronization with the rotating ring 30, the rigidity of the conductor depends on its thickness. Even if the materials are different, the supplied conductors 46 can be brought into close contact with each other, and the coil 18 can be wound tightly and evenly. Furthermore, since the unidirectional rotating roller is not kept pressed against the surface of the conductor 46 from the beginning to the end of the coil winding as in the conventional case while the coil 18 is being wound, the insulating coating of the conductor 46 is caused by friction. It is possible to always produce coils of excellent quality without the risk of damage.

Next, a mandrel is provided that creates a coil by repeating the winding operation in the opposite direction, and a movable housing that moves along the axial direction of this mandrel is provided, and this movable housing is provided with a coil that is wound around the same axis as the mandrel. A rotating ring is provided which is rotationally driven to receive the outermost side of the coil, and the coil is wound on a support body which is rotated synchronously with the rotating ring, and the coil is wound inward from the inner circumferential surface of the rotating ring. A plurality of clamp members each having a suppressing portion that presses an inner circumferential surface are movably provided, and a biasing means is provided that urges the suppressing portion of the clamp member in a direction in which the suppressing portion comes into pressure contact with the inner circumferential surface of the coil. When each of the plurality of clamp members is moved to the vicinity of the conductor supply portion as the support body rotates, the clamp member is moved against the biasing means to cause the suppressing portion to close to the inner circumferential surface of the coil. Since the movable housing is provided with a cam that separates the conductor from the conductor, even if the rigidity of the conductor varies depending on its thickness and material, the coil can be wound tightly and evenly, and the This provides an excellent effect in that there is no risk of the insulation coating of the conductor being damaged.
