One of the displaceable collars is It is attached to the body so as to be displaceable along the central axis.

[0003] In one prior art winding or unwinding device for a filament, one displaceable collar is fixed to a body by a fastener such as a bolt, and the collar is displaced according to the dimensions of the filament. In this case, the fastener was loosened to adjust the position of the tsuba. Further, in other conventional filament winding or unwinding devices, the flange is positionally displaced by a motor mounted on the body, and the motor is supplied with power via a slip ring.

[0004]

However, in the conventional technique for fixing the displaceable collar by the tightening tool, it takes a lot of time and labor to adjust the position of the collar, and in particular, the body and the collar are divided in the circumferential direction. In the case of being composed of a plurality of segments, there is a drawback that the time and labor required for the work are further increased. Further, in the conventional technique in which the collar is displaced by the motor, there is a drawback that maintenance of the slip ring is required, which causes a problem such as a short circuit of the slip ring.

The object of the present invention is to avoid the above-mentioned drawbacks and to wind the filamentous body which can adjust the position of the brim in a short time without requiring labor and using a slip ring. Alternatively, it is to provide a feeding device.

One of the collars 20 is attached to the body portion 16 so as to be displaceable along the central axis 12, and this collar 20 is
It is connected to the screw driving means 50 supported by the body segment 16A of the body 16. This screw driving means 50 is
A screw screw 52, which is rotatably supported by a mounting disk 28, is screwed to a base portion 20a of each collar segment 20A of the collar 20, and displaces the collar segment 20A along the central axis 12, and is arranged in a stand 34. It comprises a collar driving motor 54 and a transmission mechanism 58 including a clutch 56 connecting the collar driving motor 54 and the screw screw 52. The slide shaft 60 fixed to the mounting disk 28 so as to extend parallel to the screw screw 52 and slidably penetrating the base portion 20a of the collar segment 20A enables the collar segment 20A to be stably displaced. Has the function of holding.

The transmission mechanism 58 is fixed to an intermediate gear 66 fixed to a rotating cylinder 64 rotatably attached to the intermediate shaft 26 via a bearing 62, and fixed to the end of each screw 52 meshing with the intermediate gear 66. Drive gear 68 and rotary cylinder 6

6 is provided between the output shaft of the collar drive motor 54 and the sprocket 72.

Next, the use state of the winding or feeding device 10 of the present invention will be described in detail. Normally, the screw driving means 50 is used.
Since the clutch 56 of the screw is disengaged, the screw drive means 50
Is not driven, and the collar 20 is fixed without being displaced. In this state, when the body drive motor 36 of the body drive means 24 is driven, the sprocket 40 and the chain 4
2, the intermediate shaft 26 is driven through the sprocket 38,
Therefore, the bobbin main body 22 is rotated via the mounting disk 28 fixed to the intermediate shaft 26. Therefore, the filament body is wound between the collars 18 and 20 on the body portion 16 of the bobbin main body 22. At this time, the screw screw 52 and the drive gear 6
Since 8 revolves around the axis of the central shaft 12 together with the mounting plate 28, the intermediate gear 66 and the rotary cylinder 64 holding the intermediate gear 66 are rotated at the same speed in the same direction as the mounting plate 28 so that the screw screw 52 does not rotate. Rotates about the axis of the central shaft 12. At this time, the clutch 56 is rotated by the rotary cylinder 64.

On the other hand, when it is desired to change the winding width of the bobbin main body 22, the braking portion 44 of the body driving means 24 is brought into a braking state to fix the intermediate shaft 26, and the clutch 56 is engaged to engage the collar driving motor 54. To drive. When the collar driving motor 54 is driven, the rotary cylinder 64 rotates via the transmission mechanism 58, and the intermediate gear 66 integrated with the rotary cylinder 64 rotates. Therefore, the collar segment 20A screwed to each screw screw 52 is displaced along the axis of the central shaft 12 in a direction to approach or separate from the corresponding collar segment 18A according to the rotation direction of the screw screw 52. .

In the above embodiment, the collar segment 20A is used.
When the position is displaced, the intermediate shaft 26 is braked by the braking portion 44. However, since the bobbin main body 22 including the mounting plate 28 cannot rotate unless a driving force that is considerably larger than the driving force required to displace the collar segment 20A is applied, it is not possible to rotate the collar segment 20A. The bobbin body 22 does not rotate. The braking portion 44 is provided on the intermediate shaft 26.
Although the work can be performed more safely by braking the brake, the brake unit 44 is not always required.
