  However, in the technique described in Patent Document 2, a winder is installed inside the rotating body formed by the rotation of the guide mechanism, and electric power is supplied from the outside of the rotating body to adjust the winding tension. Need to supply. Conventionally, a twist ring machine is provided with a slip ring and a carbon brush for supplying electric power to an electric adjusting mechanism. When such an electric adjustment mechanism is employed, the following problems (a) to (d) occur.

(A) While the stranding machine is in operation, the carbon brush that rubs against the slip ring wears over time, and wear powder scatters in the stranding machine, thereby fouling the wall surface of the equipment, parts and pass lines, and Adhering to the surface of the stranded wire may cause abnormal appearance.
(B) Since the inside of the facility becomes dirty, the operator in charge of operation needs to clean the inside of the facility periodically (every time the strand is replaced with the guide mechanism).
(C) It is necessary to periodically replace the worn carbon brush with a new one.
(D) When a power failure occurs due to lightning or the like, the equipment is suddenly stopped, so that the stranded wire is broken. Specifically, when a power failure occurs, the electric clutch is disengaged and winding is stopped, while the guide mechanism continues to rotate due to inertia, and the wire that is not wound is continuously twisted and cut. In particular, when the wire is an extra fine wire, it is easy to cut.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a plurality of strands in a twisting machine provided with a winder in a rotating body formed by the guide mechanism and its rotation. When forming a stranded wire from a wire, it prevents equipment that has a winding tension adjusting mechanism as a factor and the surface of the stranded wire from being damaged and the strands from being cut in the event of a power failure. It is to make it possible to reduce.

The stranded wire manufacturing method according to the present invention is a stranded wire manufacturing method in which a plurality of strands are twisted together to manufacture a stranded wire, wherein the plurality of strands are assembled and applied to a guide mechanism, and the guide mechanism The twisted wire is formed by winding the twisted wire with a winder installed inside the rotating body formed by the rotation of the guide mechanism. The winding tension of the winder is adjusted by a magnetic variable torque control mechanism attached to the rotating shaft, and the wire is a conductor having a diameter of 0.025 mm or less .

  According to the present invention, when a stranded wire is formed from a plurality of strands, in a twisting wire machine provided with a winder in a rotating body formed by the guide mechanism and its rotation, the magnetic variable torque control mechanism Do not use slip rings or carbon brushes to adjust the winding tension. Accordingly, there is no equipment attached to the use of the carbon ring, the surface of the stranded wire, and the cutting of the strands in the event of a power failure, and there is no need to replace the carbon brush.

It is a figure which shows one structural example of the strand wire machine which concerns on one Embodiment of this invention.

[Details of the embodiment of the present invention]
A specific example of a stranded wire manufacturing method and a stranded wire machine (twisted wire manufacturing apparatus) according to an embodiment of the present invention will be described below with reference to FIGS. 1, 2A, and 2B. FIG. 1 is a diagram showing an example of the configuration of a stranding machine according to an embodiment of the present invention, and FIG. 2A is a winding machine of the stranding machine of FIG. FIG. 2B is a top view showing the variable torque control mechanism (when maximum torque is generated).

  As shown in FIG. 1, the twisting machine 1 according to this embodiment is a double twist buncher type twisting machine, and includes a supply 11, a die 12, a shaft body 13, support bases 14 and 19, and a first twisting part 15. , An arcuate guide member 16, a second twisted portion 17, a rotating shaft body 18, a take-up capstan 20, a guide roller 21, and a take-up drum 22. As will be described later, the twisting machine 1 is provided with a magnetic variable torque control mechanism as shown in FIG. 2A as a tension adjusting mechanism.

  The supply 11 is a supply such as a reel that feeds out a plurality of strands 10a. In this example, the supply 11 is provided by the number of each strand 10a, but a plurality of strands 10a are provided in one supply 11. It may be wound.

  The die 12 serves as a twisting hole for collecting (collecting) the plurality of strands fed from the supply 11. A strand guide for guiding the strand 10 a may be provided between the supply 11 and the supply 11. Although the strand 10a twisted with the illustrated twisting machine 1 is generally a conductor, it is not restricted to this.

  The shaft body 13 is a shaft that is rotatably supported by the support base 14. A die 12 is provided on one end side, and a first twisted portion 15 is provided on the other end side. The rotating shaft 18 is a shaft that is rotatably supported by a support 19 provided at a position facing the support 14. And the 2nd twist part 17 is provided in the edge part of this rotating shaft body 18. As shown in FIG.

  The guide member 16 is a member that forms the stranded wire 10c by hooking and rotating the assembled plurality of strands 10a, and is disposed between the first stranded portion 15 and the second stranded portion 17. A pair of arc-shaped (bow-shaped) members. The guide member 16 may be provided with a plurality of guide dies or the like for penetrating the respective guide lines, or a bow-shaped outer surface may be formed in a groove shape. Although not shown, the guide member 16 can be rotated by providing the twisting machine 1 with a drive unit such as a motor and a transmission mechanism such as a belt for transmitting the drive.

  The winding drum 22 is an example of a device that is installed inside a rotating body formed by the rotation of the guide member 16 and winds the twisted twisted wire 10c, and a winding roll or the like can be employed instead. . Further, a take-up capstan 20 and a guide roller 21 are provided between the winding drum 22 and the second twisted portion 17. It can be said that the take-up capstan 20 and the guide roller 21 are part of the winder.

  In the stranding machine 1, first, each strand 10a is led from the supply 11 to the die 12, and is assembled by the die 12 to form a strand group 10b. Next, the strand group 10 b is hung on the guide member 16 through the inside of the shaft body 13 and the inside of the first twisted portion 15, and becomes the twisted wire 10 c through the inside of the second twisted portion 17. Specifically, the strand group 10b is given the first twist by the first twisted portion 15 and the second twist by the second twisted portion 17 by the rotation of the guide member 16, and thereby the twisted wire 10c. Is formed. Then, the stranded wire 10 c is taken up by the take-up drum 22 via the take-up capstan 20 and the guide roller 21.

As a main feature of this embodiment, the take-up drum 22 has a magnetic variable torque control mechanism attached to the rotating shaft thereof.
The variable torque control mechanism in this example includes two magnets 28 and 29 and one disk 27 as illustrated in FIG. 2A. Each of the magnets 28 and 29 has a through hole at the center. The disk 27 is fixed to a shaft 25 that serves as a rotating shaft of the winding drum 22. The shaft 25 is rotatably held by bearings 26a and 26b disposed on the outer sides of the flange portions 24a and 24b at both ends of the body portion 23 of the winding drum 22, respectively.

  When the disk 27 rotates, the magnetic force acting between the two magnets 28 and 29 works so as to prevent the disk 27 from rotating. This resistance force changes depending on the relative positions of the magnetic poles of the magnets 28 and 29. In the case of the positional relationship as shown in FIG. 2A, the torque becomes minimum, and in the case of the positional relationship as shown in FIG. 2B, the torque becomes maximum.

  As described above, according to the present embodiment, since the magnetic force type mechanism is adopted as the winding tension adjusting mechanism, the electric clutch is used as the winding tension adjusting mechanism when forming a stranded wire from a plurality of strands. The above-mentioned problems (a) to (d) can be solved.

  Thus, in this invention, the slip ring and carbon brush for supplying electric power in the rotating guide member are not used. Thereby, the abrasion powder of a carbon brush does not generate | occur | produce, and there is no stain | pollution | contamination in an apparatus by it and the appearance abnormality of a twisted wire. Moreover, there is no need to clean the wear powder or to replace the carbon brush.

  Moreover, when the strand 10a is thin when using the electric clutch, the strand is excessively twisted and cut by rotating the guide member due to inertia during a power failure. In the present invention, the clutch is not disengaged even when a power failure occurs, and the winding drum rotates by inertia. Therefore, even if the guide member continues to rotate by inertia, the strands are not twisted to the extent that the strands are broken. Therefore, when the strand 10a is a thin conductor of 0.025 mm or less, the effect of the present invention that the strand is not broken is particularly great.

  In addition, in FIG. 1, an example in which an arcuate guide member is employed as an example of a simple configuration of the guide mechanism is described. However, as described in Patent Document 1, there is no hook-shaped guide member (there is no intermediate part of the arc shape). By adopting a mechanism such as a guide member having such a shape or a guide member having a guide roller at the tip, a simple configuration can be obtained. When a mechanism that straddles the winding drum 22 such as the bow-shaped guide member 16 is not adopted as the guide mechanism, the rotating body includes a guide mechanism and N strands 10a guided there. This means a rotating body formed by rotating. By adopting any guide mechanism including the guide member 16, the stranded wire machine can have a simple configuration.

  In the stranded wire manufacturing method according to the present embodiment, as can be seen from the manufacturing process in the twisting machine 1, N strands 10a are assembled and hung (attached) to a guide mechanism such as a guide member 16 and the guide mechanism. The twisted wire 10c is formed by rotating and twisting. And the twisted wire 10c is wound up with winding machines, such as the winding drum 22 installed inside the rotary body formed by rotation of this guide mechanism. Here, the take-up tension of the take-up drum 22 is adjusted by the above-described magnetic-type variable torque control mechanism attached to the shaft 25 serving as the rotation axis of the take-up drum 22. About the other application example of this twisted wire manufacturing method, it is as having demonstrated the twisted wire machine 1. FIG.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of claims for patent, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims for patent.
