Example of Invention

An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, (6) is a winding frame formed in a torus shape, (7) is a wire drum provided with a wire (8) wound around the winding frame (6), for example, a coil wire, ( 9)
Is a tension generator that adds a constant tension to the wire (8), and (10) is a retracting mechanism that supports the reel (6) at multiple points and saves when it interferes with the wire drum (7) that occurs in the winding. A plurality of holding mechanisms including, for example, a support tool (10
A retracting mechanism is constructed by expanding and contracting a) up and down. Reference numeral (11) is a first rotating mechanism that supports the holding mechanism (10) and rotates the reel (6) in the torus direction via the holding mechanism (10). The rotating table supports the holding mechanism (10). (12) and a drive device (13) for rotating the rotary table (12). In (14), the winding frame (6) is rotatably inserted in the torus direction on the inner peripheral part, the wire drum (7) and the tension generator (9) are mounted,
It is a second rotating mechanism that rotates in the direction intersecting the torus direction with the reel (6) as the center of rotation, and rotates in a direction intersecting with the torus direction with the reel (6) as the center of rotation, for example, rotation divided into two. Head (15) and this rotating head (15)
The rotating head (15) is provided with a wire drum (7) and a tension generator (9) and rotates in conjunction with the rotating head (15). (17) is a frame for fixing the second rotating mechanism (14) to the bed (18) in a rotatable state.

Next, the operation will be described. First, the end of the wire (8) from the wire drum (7) attached to the rotary head (15) is passed through a tension generator (9) to add a constant tension and to fix it to the reel (6). Next, the drive device (13) is driven to rotate the rotary table (12), and the reel (6) is rotated in the torus direction via the holding mechanism (10). In conjunction with the rotation of the reel (6) in the torus direction, the drive device (1
6) is driven to rotate the rotating head (15) in a direction intersecting the torus direction, and the wire drum (6) and tension generator (9) are also in the torus direction in conjunction with the rotation of the rotating head (15). Rotate in the direction intersecting with. By rotating both the rotary table (12) and the rotary head (15), the wire (8) of the wire drum (6) is wound around the winding frame (6) with a certain tension added. Further, when the winding drum (6) interferes with the wire drum (6), the support tool (10a) of the holding mechanism (10) is lowered, and when there is no interference, the support tool (10a) is raised to raise the reel ( Support 6). In this way, a torus-shaped winding such as a helical winding can be wound with a constant tension added.

In the above embodiment, the case where the wire is composed of a coil winding has been described, but it goes without saying that a tape-shaped wire such as an insulating tape is also included.

Further, in the above-mentioned embodiment, the case where the tension generator acts directly on the wire has been described, but it may be made to indirectly act on the wire via the drum.

Further, in the above-mentioned embodiment, the case where the holding mechanism is the telescopic type has been described, but the same effect can be obtained by the hanging type, the link type and the like.

Further, in the above embodiment, the case where the rotary head is divided into two has been described, but the same effect can be obtained even with the C-type structure.
