2. Description of the Related Art In a cage type collecting apparatus, it is necessary to provide a planetary gear mechanism in each of the cage flyers in order to impart a twisting rotation to all of the delivery bobbins provided in a plurality of zones between the cage flyers. .

[0003]

However, in order that the planetary gears rotating the delivery bobbin do not collide with each other, it is necessary to support the delivery bobbin at appropriate intervals in the circumferential direction of each cage flyer. There is a disadvantage that the number of delivery bobbins is limited. Further, in order to solve this inconvenience, there is a disadvantage that the number of zones must be increased by increasing the number of cage flyers, and there is a disadvantage that the size of the machine is generally increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1A denotes a hollow shaft to be passed through a core (a linear body with an SZ groove or a core located at the center), and a hollow main shaft 4 is rotatably provided coaxially outside the hollow shaft. The required rotation, the reversal period of the SZ groove (not shown) which is separately measured in the case of the striated body with the SZ groove, and the normal and reverse in accordance with the desired SZ twisting pitch in the case of the general multilayer stranded wire. A rotation is given.

A desired number of cage flyers 5A, 5B, 5C, 5D, in this example, generally disk-shaped, are fixed to the main shaft 4 at appropriate intervals in the longitudinal direction, and in this example, four cage flyers 5A, 5B, 5C, 5D are interposed therebetween. , A first zone, a second zone, and a third zone are sequentially partitioned. A slip ring 17 is attached to the left end, and a wiring pipe 9 is provided in a hollow portion between the slip ring 17 and the outer wall of the hollow shaft 1A. A disc brake device (16A, 16B) for braking is attached.

A sun gear 10 having an appropriate number of teeth is fixed to one side of a cage flyer 5A of the main shaft 4, and a planet fixed to one end of a rotary shaft provided through the cage flyer 5A in a direction parallel to the main shaft. It meshes with the gear 11. Further, a spur gear 12 having an appropriate number of teeth is fixed to the other end of the rotating shaft on the other side of the cage flyer.

[0008] Another transmission shaft 14 is a cage flyer 5A, 5
B and 5C are also provided so as to penetrate in a direction parallel to the main shaft 4, and a twisting drive gear 13 is fixed to the transmission shaft 14 and meshes with the spur gear 12 described above. Thus the sun gear 1
0, the planetary gear 11 and the twisting drive gear 13 meshing indirectly with the planetary gear 11 constitute a planetary gear mechanism.

[0009] Equal number, in this example, eight bobbin supporting frames 6 are hollow at each equally spaced position near the outer periphery of each cage flyer 5A, 5B, 5C in each zone between adjacent cage flyers. It is rotatably suspended by the shaft 6A. The bobbin support frame 6 is provided with a delivery bobbin 7 for the element wire 3 (optical fiber core wire or metal element wire) so as to be rotatable around its own axis.

A pulley 23 is fixed to the end of the hollow shaft 6A. On the other hand, a pulley 18 is
As shown in FIG. 2, the timing belt 21 is wound around the pulley 18 in a heart shape (V shape) between a total of three pulleys including two pulleys 23 adjacent thereto.

The same applies to the cage flyers 5B and 5C. FIG. 2 is a plan view showing the state in which the timing belts 21 and 22 are wound around in a circumferential direction for easy understanding. As you can see from the figure,
In the first zone and the second zone, the pulleys 23 of the two bobbin support frames on which the timing belt is hung are angularly shifted.

A slip ring 8 is provided at the outer end of the hollow shaft 6A that supports the bobbin support frame 6. This is to supply electricity supplied from the slip ring 17 by the wiring 19 passing through the inside of the wiring pipe 9 to an electromagnetic brake or the like of the sending bobbin 7 for sending and braking.

The above-mentioned planetary gear mechanism gives the bobbin support frame 6 a twisting rotation in the opposite direction to the rotation of the cage flyer 5A or the like. In this way, the strand 3 sent out from the delivery bobbin 7 is twisted and guided to the collecting position through the guide pipe 15. It is clear from the drawing that the bobbin supporting frame 6 of the cage flyers 5B,... Other than 5A is rotationally driven by the transmission shaft.

[0014]

According to the present invention, since two sets of delivery bobbins can be simultaneously twisted and rotated by driving one set of timing belts, each delivery bobbin is individually twisted and rotated by a planetary gear mechanism or the like. The advantage of this is that the entire machine can be compactly arranged regardless of the increase in the number of delivery bobbins that can be supported.
