Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for twisting filaments, and particularly to a method for twisting filaments that can simultaneously twist filaments having different outer diameters. It is something.

[Prior art] Device wires used as wiring materials for electronic and electrical equipment are becoming increasingly finer due to the high density packaging of devices, and twisting machines are also designed to prevent conductors from elongating and breaking. In order to support higher speeds, miniaturization is being attempted to match the size of the conductor. Furthermore, a plastic bobbin with an outer diameter of 300 mm or less is used as the bobbin, which has advantages such as being lighter, cheaper, and easier to handle than metal bobbins.

As a method of twisting together a plurality of insulated core wires made of conductors having a thin outer diameter of 0.24 mm, a method using a cage type twisting machine as shown in FIG. 4 is known.

In this twisting method, a central inclusion 3 fed out from a bobbin 2 installed on a supply stand 1 is passed through a hollow noon shaft 5 attached to a cage 4.

Subsequently, the center inclusion 3 is fixedly attached to one end of the hollow main shaft 5 and is passed through the center hole 6 of a cluster batten 10 provided in alignment with the hollow of the main shaft.

On the other hand, a large number of insulated core wires 8 drawn out from a plurality of bobbins 7 installed in the cage 4 are passed through a peripheral hole 9 provided at the periphery of the center hole 6 of the cluster batten 10. The central inclusion 3 and the large number of insulated core wires 8 that have passed through the collective perforated plate 10 are inserted into a fixed die 11 and replaced. Next, the twisted cable 12 is taken up by a take-up machine 13 and wound up by a take-up machine 14.

[Problems to be Solved by the Invention] When superfine insulated core wires with an outer diameter of 0.6 mm or less are twisted together using the conventional cage type twister described above, the bobbin generally has an outer diameter of about 130 mm. A plastic bobbin of approximately this outer diameter is suitable, and the amount of winding of ultra-fine insulated core wire exceeds 2000 m, and since it is lightweight, the tension burden on the insulated core wire can be reduced, and the rotation speed of the cage can be reduced. I come a lot.

However, when twisting a stranded cable with a configuration including composite twisted insulated core wires or shielded pair wires as shown in Figure 3, the outer diameter of the composite twisted insulated core wire is extremely large compared to the outer diameter of the insulated core wire. Because it is so thick, if you try to wind it on the same bobbin that is used to wind insulated core wire, the amount of winding will be extremely small, making it impossible to make long strips.

For example, if the outer diameter of the insulated core wire is 0.6 mm and the outer diameter of the shield composite twisted insulated core wire is 3 mm, the outer diameter is 130 m.
The amount of winding when wound on a plastic bobbin of m is 2000 m for the insulated core wire and 80 m for the shield composite twisted insulated core wire, so it is not possible to make a long strip. Therefore, in order to manufacture long-stripe twisted kepuru, the outer diameter is 3.
It is necessary to use a large plastic bobbin (for example, outer diameter 300 mm) with a winding amount that matches the insulated core wire of mm and use a large twisting machine to perform the twisting work, but the large twisting machine does not increase the rotation speed and is able to twist efficiently. Unable to work together.

In other words, in order to simultaneously twist together an insulated core wire with an outer diameter of 0.6 mm and an insulated core wire with an outer diameter of 3 mm, (1)
A large twisting machine using a large plastic bobbin that matches the outer diameter of 3 mm and the length of the thread (2) A small twisting machine that uses a small plastic bobbin that matches the outer diameter of 0.6 mm and the thread length can be used. However, in case (1), since the bobbin size is large, the cage is also large, and the number of rotations of the poppy cannot be increased. In the case of (2), the amount of winding of the insulated core wire with an outer diameter of 3 mm is extremely small, making it possible to work with long wires, and the number of setups increases, resulting in inefficiency.

The present invention aims to improve the drawbacks of the prior art described above, and to provide a method for twisting filament bodies that can simultaneously twist filament bodies having different outer diameters and perform the twisting work efficiently. It is something to do.

[Means for Solving the Problems] The present invention includes a rotating die that is provided coaxially with the center hole and rotates in the same direction as the center hole of the threaded body that has passed through the center hole of the set batten. Then, the filament is passed through one circumferential hole of a sub-aggregated batten, which similarly to the clustered batten has a center hole and a number of peripheral holes, and further inserted into a fixed die, while At least one of the many filaments that have passed through the peripheral hole is passed through the center hole of the sub-assembly batten, and the remaining filaments are passed through the peripheral hole, further inserted into a fixed die, and their It is constructed so that the filaments are twisted together using a fixed die.

By installing a plurality of cage-type combing machines used in the present invention in tandem and twisting them together, a twisted cable consisting of a plurality of filament bodies including filament bodies having different outer diameters can be obtained.

[Operation] The method of twisting the filament bodies of the present invention is to pass the filament bodies that have passed through the center hole of the aggregated batten through a rotating die provided coaxially with the center hole, and then pass the filament bodies through the sub-gauge plate. Pass through one peripheral hole of the board and further insert it into a fixed die, while at least one of the many filaments that have passed through the peripheral hole of the collective batten into the center hole of the sub-batten. At the same time, the remaining filament bodies are passed through the peripheral hole, further inserted into a fixed die, and the filament bodies are twisted together by the fixed die, so that the filament bodies with a small outer diameter are paid out from the cage. Since the filament bodies having a large outer diameter can be fed out from the supply stand, the twisting speed can be increased and a plurality of filament bodies can be twisted into long strips. Therefore, filament bodies having different outer diameters can be simultaneously and efficiently twisted together.
