Description of Embodiments Embodiments of the present invention will be described below.

In FIG. 1, this apparatus has a disk-shaped rotating body 1, which is rotatably supported about a central axis 2. In this embodiment, a hollow support shaft 3 is arranged and fixed on the central shaft 2, and the rotating body 1 is rotatably supported by the support shaft 3. Therefore, the decorative thread 4 such as gold and silver thread can be passed through the hollow support shaft 3.

This device has two rotating shafts 5. The rotating shaft 5 extends in parallel with the central axis 2, is arranged at angular intervals around the central axis 2, and is rotatably supported by the rotating body 1. As shown in FIG. 2, the angular interval is 180 °. Furthermore, two bobbins 6 are combined with it,
Each bobbin 6 is provided on each rotating shaft 5. The bobbin 6 is obtained by winding a decorative thread 7 such as gold and silver thread, and is rotatably supported by the bobbin shaft 9 of the housing case 8, and the housing case 8 is fixed to the rotating shaft 5.

Further, a sun gear 10 is used to rotate the rotary shaft 5, the sun gear 10 being concentrically arranged on the central shaft 1 and being rotatably supported on the support shaft 3. Further, two planet gears 11 are combined therewith, and each planet gear 11 is provided on each rotating shaft 5, fixed, and meshed with the sun gear 10. Sun gear 10
Has 60 teeth and the planetary gear 11 has 20 teeth.

Further, a motor 12 is used as a drive mechanism for the rotating body 1 and the sun gear 10, and a belt 13 is used.
The motor 12 and the transmission shaft 14 are connected by. The transmission shaft 14 extends parallel to the central axis 2 and has a speed change pulley 15. Further, the speed change pulley 15 and the rotating body 1 are connected by a belt 16, and the speed change pulley 15 is connected by a belt 17.
And the sun gear 10 are connected.

In addition, the worm wheel 18 has a transmission shaft 1
It is engaged with the worm 19 of No. 4 and is connected to the pinch roller 20. The pinch roller 20 is for drawing out the decorative threads 4 and 7. Furthermore, the worm wheel 1
8 is connected to the drive wheel 21, and the drive wheel 21 is the take-up reel 2
The second drive shaft 23 is slidably engaged. The take-up reel 22 is for taking up the decorative threads 4 and 7.

In this apparatus, the support shaft 3 and the bobbin 6
The decorative threads 4 and 7 of the pinch roller 20 and the take-up reel 2
When the transmission shaft 14 is rotated by the drive motor 12 and the belt 13, the rotating body 1 is driven and rotated by the speed change pulley 15 and the belt 16. As a result, the rotary shaft 5, bobbin 6 and planetary gear 11 rotate. The rotating shaft 5, the bobbin 6 and the planetary gear 11 rotate along the sun gear 10 and rotate clockwise in FIG. At the same time, the sun gear 10 is driven and rotated by the speed change pulley 15 and the belt 17. The sun gear 10 is also shown in FIG.
Rotate clockwise. The speed is higher than the turning speed of the planetary gear 11. Therefore, the planetary gears 11 are driven and rotated by the sun gear 10. The planetary gear 11 rotates counterclockwise in FIG. 2, and the rotating shaft 5 and the bobbin 6 also rotate integrally with the planetary gear 11.

Further, the pinch roller 20 is driven and rotated by the worm 19 and the worm wheel 18. Further, the worm wheel 18 drives the drive wheel 21.
Is driven and rotated, and the take-up reel 2 is driven by the drive wheel 21.
2 is driven and rotates. Therefore, the pinch roller 2
Decorative threads 4 and 7 are pulled by 0 and one decorative thread 4
Is pulled out from the spindle 3, and the two decorative threads 7 are attached to each bobbin 6
Each of the decorative yarns 4 and 7 is pulled out from the reel, passes through the pinch roller 20, and is wound around the winding reel 22.

Therefore, in this device, when the decorative yarn 7 is pulled out from each bobbin 6, each bobbin 6 is swung by the rotating body 1. At the same time, each bobbin 6 is rotated by the sun gear 10 and the planetary gear 11. Therefore, the plurality of decorative threads 4 and 7 are combined and twisted in a weakly twisted state, which passes through the pinch roller 20 and is wound around the winding reel 22. Moreover, as the bobbins 6 rotate and rotate, the decorative threads 4 and 7 are twisted together in a twisted state. Therefore, it is possible to properly twist them together, and the twist does not return even if time passes.

FIG. 3 shows another embodiment. In this embodiment, three bobbins 6 are provided on the three rotary shafts 5, three planetary gears 11 are provided on them, which are angularly spaced around the central axis 2 and rotate on the rotor 1. Supported as possible. The angular interval is 120 °. Therefore, decorative threads such as gold and silver threads can be pulled out from the three bobbins 6 and can be twisted together in a weakly twisted state. It is possible to further increase the number of bobbins 6, the rotation shaft 5, and the planetary gears 11.

[0015]

As described above, according to the present invention, the plurality of bobbins 6 are swung by the rotating body 1. At the same time, each bobbin 6 is rotated by the sun gear 10 and the planetary gear 11. Therefore, a plurality of decorative threads 4, 7
Can be twisted together in a weakly twisted state. Moreover, as the bobbins 6 turn and rotate, the respective decorative threads 4, 7
Is twisted in a twisted state, and this can be twisted properly, and the twist does not return, so that the intended purpose can be achieved.
