Description

[Detailed description of the invention] This invention relates to an SZ twisting and gathering device.

Conventionally, the collecting device creates collected cables that are twisted in one direction in the S-twist direction or the Z-twist direction, but recently S-twist cables and Z-twist cables are being used to offset the torsional torque of the entire cable, for example in elevator control cables. Cables that were connected in parallel and integrated began to be used.

This invention is a double-side introduction type SZ twist simultaneous gathering device that can simultaneously gather S-twist collecting cables and Z-twist collecting cables and wind the windings on the rotating frame of one winding rotation device in parallel from both sides on the bobbin. It provides:

The present invention also provides a novel SZ twisting and simultaneous gathering device which can also be used for gathering S or Z unidirectionally twisted gathering cables.

An embodiment of the invention will be described with reference to the drawings.

In FIGS. 1 and 2, the ones indicated as IA and IB as a whole are feed-out bobbin groups to be assembled with twists in opposite directions, and each feed-out bobbin 11 has, for example, a pair-twisted wire or a quad-twisted wire. etc. are wrapped.

Twisted wire group S sent out from sending bobbin groups IA and 1B
are respectively passed through guide rolls 2A, 2B for direction rotation; the same <3A, 3B, and pass through dividing plates 4A, 4B, respectively, and are collected in collecting dies 5A, 5B, respectively.

Twisted wire group S sent from one sending bobbin group 1A
are gathered together in the gathering die 5A, and twisted by the rotation of the rotating frame 71 of the take-up device 7 while being twisted by the taping device 6.
It is taped up by A.

If the rotating direction of the rotating frame of the pulling device 7 is set, for example, in the direction of the arrow shown in the figure, this twisted wire group S becomes a Z-twisted collective cable 10.
A is passed between a pair of rolls 72 and 73 of a take-up device, and is drawn in, introduced from the right side of the take-up and rotation device 8, and passed through a traverse roller 84A to the take-up bobbin 83.
It is wound up.

On the other hand, the stranded wire group sent from the other sending bobbin group 1B is collected in the collecting die 5B, and then directly introduced from the left side of the winding and rotation device 8 through the taping device 6A, and is also wound up through the traverse roller 84B. bobbin 83
The number of rolls is increased.

The take-up and rotation device 8 has a rotary frame 82 rotatably supported on a base 81, on which is mounted the take-up bobbin 83, which is driven one rotation by a torque motor or the like, and traverse shafts 85A and 85B, respectively. The above-mentioned traverse rollers 84A and 84B are provided.

In this case, if the rotation direction and rotation speed of the rotation frame 82 of the take-up rotation device 8 are the same as those of the rotation frame 71 of the take-up device 7, the stranded wire sent from the left side from the delivery bobbin group 1B The group is twisted as an S-twist aggregate cable 10B, and the aggregate cable 10A from the right
It is clear that the twist already given by the rotation of the rotating frame 71 of the take-up device 7 is introduced without any change and is wound onto the take-up bobbin 83.

That is, in the device of this invention, as shown in an enlarged view in FIG. 3, the stranded wire group from one sending bobbin group 1A is used as a Z-twisted aggregate cable 10A, and the stranded wire group from the other sending bobbin group 1B is are wound around the same winding bobbin 83 as the S-twist aggregate cable 10B.

Specifically, the feed amount of the traverse shafts 85A, 85B may be set equal to the width of two collective cables per rotation of the winding bobbin 83.

Note that this S-twist cable 10B and Z-twist cable 10
As shown in Fig. 4, the winding method A involves inserting a partition plate 87 in the center of one winding bobbin 83 to clearly divide the winding area into two parts, and then inserting a set of cables twisted in opposite directions into each part. When winding and pulling out, the two may be combined to form an Sz parallel cable.

One of the important features of the device of the invention is that there is only one take-off device 7 on each side.

This is because the winding speed of the winding bobbin 83 is regulated by the take-up speed of the take-up device 7, and the collected cables on the side where the take-up device is not provided are connected to the collected cables on the other side by the rotation of the take-up bobbin 83. It is wound at exactly the same linear speed as the cable 10A, thus making it possible to wind the collective cables 10A and 10B from both sides in parallel at the same speed.

Another feature of the device of the invention is that it can also be used as a conventional unidirectional twist gathering device.

That is, in this case, the stranded wire group from the delivery bobbin group 1B passes through the guide roll 9, and is merged with the stranded wire group S from the delivery bobbin group 1A at the guide roll 2A, and then the wire splitting plate 4A, the gathering die 5A, It is only necessary to guide the tape to the taping device 6A, the take-up device 7, and the take-up and rotation device 8.

As described above, the apparatus of the present invention (1) can simultaneously manufacture SZ twisted cables, and (■) can produce S-twisted cables and Z-twisted cables at the same speed to one bobbin by providing a pulling device only on one side. Parallel winding is possible (i
ii) It has many effects, such as being able to be used for aggregating unidirectionally twisted cables containing multiple stranded wires.
