Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for twisting cable wires, and more particularly to a method for twisting a large number of strands using a small number of supply frames.

[Technical features of the invention and its problems 1 Conventionally, when twisting cable cores, especially large-sized cable cores, a winding rotation type twisting machine has been used (
, a plurality of supply stands mounted with supply bobbins are twisted together and rotated around the central axis, and these supply stands are rotated in the opposite direction to the twisting direction to apply untwisting, and the cables are removed from each bobbin. A method is adopted in which the cores are pulled out, passed through a batten, collected at the twisting end, and twisted while being continuously pulled out.

However, with this method, only the number of cable cores equal to the number of supply frames can be twisted together, and therefore, when the number of cores increases, it is necessary to prepare an equivalent number of supply frames each time, which requires equipment. There was a problem with increasing the size.

If multiple bobbins wrapped with cable cores are mounted on a fixed frame and the cable cores are pulled out from these bobbins while being twisted, there is no limit to the number of cores, but in this case, it is difficult to untwist the cable cores. There was a problem in that the cables could not be connected to each other, causing the twisted cables to undulate or undulate.

[Purpose of the Invention] The present invention was made to solve such problems, and its purpose is to provide a method for twisting a larger number of strands than the number of supply frames without causing twisting or waviness. do.

[Summary of the Invention] That is, the method for twisting strands of the present invention involves pulling out each strand from a bobbin mounted on a plurality of supply racks,
The first step is to collect the wires at the twisting opening through the battens, and to rotate each supply frame around the twisting central axis while continuously taking them out to perform -C twisting. The wound bobbin is mounted on the supply mount again, the strands at the drawn end are separated, and the strands are passed through the batten together with the strands wound on the bobbin mounted on the other supply mount at the C twist opening. While continuously pulling off the stranded wires, the supply pedestal on which the bobbin on which the stranded wire is wound is mounted is moved in the twisting direction with respect to the supply mount on which the bobbin on which the cable wire is mounted is mounted. The second strand rotates on its own axis and rotates each supply frame around the center axis for twisting.
It is characterized by consisting of the following steps.

[Embodiments of the invention] The present invention will be described below with reference to embodiments shown in the drawings.

In this actual flow example, first, as shown in Fig. 1, N bobbins 1 wound with strands of wire are hung on an N glue stand (not shown) in the same manner as before, and these supply stands are revolve around the twisting axis in the same direction, and each bobbin 1 is rotated in the opposite direction to the twisting direction (apparently not rotating upward) while untwisting.
After pulling out the strands 2 from each of the strands and arranging them at spatially equal positions through the battens 3, they are gathered together through the twisting spout 4, and the obtained strands 5 are wound around a bobbin 6.

Next, as shown in FIG. 2, the bobbin 6 on which the obtained stranded wire 5 has been wound is hung again on one of the first supply racks, and the stranded wire 5 at the end of the winding of the stranded wire 5 is loosened. book wire 2
Pass through batten 3. Further, a bobbin 8 on which the wire 7 is wound is mounted on another supply frame, and If-1 wire 7 is pulled out and passed through the batten 3 in the same manner. The 2N-1 strands 2.7 passed through the batten 3 are gathered together, passed through the twisting opening 4, and fixed to the winding bobbin 9.

After that, the supply frame on which the bobbin 8 wound with the strands 7 is mounted is rotated in the opposite direction to the twisting direction to apply untwisting, while the bobbin 6 around which the stranded wire 5 is wound is untwisted. The stranded wire 10 is pulled out while rotating in the opposite direction at the same speed as the rotation of the stranded wire 10 and rotating all the supply frames in the same direction as the twisting direction of the stranded wire 1.

At this time, the stranded wire 5 rotates in the opposite direction by the same amount of twist as the untwisting applied to the wire 7, so no new untwisting is added in this twisting process, and it is The untwisting added in is the twisting process.

Therefore, each of the strands constituting the C-stranded wire 10 is given the same maximum twist, so that no laughter or undulations occur.

In addition, in the example below, the present invention is applied to the stranding of stranded wires that requires untwisting, but the present invention can be similarly applied to the stranding of stranded wires that do not require untwisting. . In this case, there is no need to rotate the supply frame on which the bobbin wound with strands is mounted, and only the supply frame on which the bobbin with twisted wires is mounted needs to be rotated in the same direction as the twisting direction.

As explained above, in this embodiment, a maximum of (2N-1>) cable wires can be twisted by performing twisting twice using N supply frames.

[Effects of the Invention] As is clear from the above description, according to the present invention, by repeating the twisting process using a certain number of supply frames, it is possible to uniformly twist a large number of strands without causing curls or waviness. Can be twisted together.
