Description

[Detailed Description of the Invention] A. Field of Industrial Application This invention relates to a double-twisting wire twisting machine for twisting a plurality of filaments, and in particular, it relates to a double-twisting wire twisting machine for twisting a plurality of wires, and in particular, a single wire supply strand is placed inside the wire, and a supply wire of a single wire is placed outside. This type of winding bobbin involves winding the product onto a winding bobbin.

B. Prior Art A conventional double-twisting wire twisting machine has a structure as shown in FIG. That is, the hollow bow 4 and the hollow shafts 12, 1 at both ends of the bow 4' having the same shape at symmetrical positions.
2', the shaft is rotatably supported by bearings 5, 5', and there is provided a cradle 2 that is always stationary in the center of the internal space in which the bow rotates, and a plurality of supplies are wound therein. It has a structure in which a bobbin 3 of a wire 1 is provided. The multiple supply wires 1 (move in the direction of the arrow in the drawing) are placed in the cradle 2
It enters a hole in a rotating hollow shaft 12' from the end of the shaft 12' and is guided into the interior of the rotating bow 4 through guide rollers 6 and 7. At this time, the wires are twisted together once at part A in the drawing to form a stranded wire 15. The stranded wire 15 is pulled out from the cradle from the other end of the bow 4 through the guide roller 8 and from the other hollow shaft 12, but at this time, it is twisted a second time in section B of the drawing, resulting in a double-twisted wire. line 14, then guide roller 9
It is pulled out by the capstan 10 and wound onto the winding bobbin 11 to become a product. In this wire twisting machine, an identical bow part 3' is usually provided on the opposite side of the bow 3 in order to balance the rotation of the bow 3.

C. Problems to be Solved by the Invention In the conventional double-twisting wire twisting machine, there are restrictions on the rotation speed of the bow due to the strength of the machine, the strength of the wire, etc. As a matter of course, only one twisted wire can be twisted together at the same time, which has the disadvantage of poor productivity. Another disadvantage is that only one strand of wire can be wound onto the winding bobbin, making it impossible to manufacture a product in which two strands of wire are wound on the bobbin at the same time.

D. Means for Solving the Problems This invention provides the same bow as the bow 4 of the conventional wire stranding machine on the opposite side, and also has a plurality of strands corresponding to the strands of the two stranded wires inside the cradle. Attach the wire supply bobbin, pass the bare wire for each strand through the hollow shafts on both sides of the cradle, pass the bows on both sides, and pull out the strands from the end of each opposite hollow shaft to wind them onto the take-up bobbin. This eliminates the drawbacks of the conventional wire twisting machine.

E. Example 1 FIG. 1 is a front view showing an example of the present invention.
2 with guide rollers 6', 6 and 8, 8'
A main body in which two hollow shafts 12, 12' are connected by two hollow bows 4, 4' located on opposite sides is rotatably supported by bearings 5, 5' on both sides.
A cradle 2, which is always stationary with respect to space, is provided inside the main body, and bobbins 3, 3' of a plurality of supply wires 1, 1' are mounted in the cradle. Capstan 10 on both sides of the main body,
10' and a winding bobbin 11, 11'.

To use this wire twisting machine, pull out the wire 1 from the wire bobbin 3 on one side inside the cradle 2, pull it into the hollow shaft 12' from inside the cradle, and insert it into the guide roller 6 as shown by the arrow in the drawing. Therefore, it is guided into the inside of the bow 4, passed through the guide roller 8 from the inside of the bow 4, and pulled out to the outside through the hole in the hollow shaft 12 on the opposite side. In this way, as the bow rotates, the strands are twisted once on the entrance side to form a stranded wire 13, and then twisted once on the exit side to form a stranded wire 14, which is twice twisted. This stranded wire 14 is drawn out by a capstan 10 and wound onto a winding bobbin 11. The strands 1' of another strand bobbin 3' on the opposite side inside the cradle 2 are twisted and drawn out through the same path in the opposite direction and wound onto the winding bobbin 11'.

According to this wire twisting machine, two twisted wires can be simultaneously created and twisted twice for each rotation of the bow, and the wires can be wound onto a winding bobbin.

Embodiment 2 FIG. 2 shows another embodiment of the present invention, in which the general structure of the machine body is the same as in Embodiment 1, but the strands 14, which come out from both sides of the stranding machine 15 of the previous embodiment, 1
4' is pulled out by a common capstan 16 by guide rollers 19, 19', and 18' to a two-wound bobbin 17 that winds two strands at the same time, as shown by the arrows in the drawing. It's starting to wind up.

In this way, two twisted wires can be wound in parallel onto one bobbin.

In the above embodiment, the case where the main body is installed horizontally has been explained, but it goes without saying that the present invention can also be used when the main body is installed vertically or inclined.

F. Effects of the Invention As explained in detail above, when the wire twisting machine of the present invention is used, two twisted wires are manufactured at the same time, so one wire twisting machine can produce twice as many wires as the conventional one at the same rotation speed. production, and productivity doubles. Generally, the power required for this type of wire twisting machine is due to windage loss due to the rotation of the bow and friction loss of the shaft, and even in conventional machines, it is common to be installed on the opposite side for balance of the bow. The wire twisting machine of the present invention can produce twice as many twisted wires with the same power as conventional ones, resulting in savings in power costs. Furthermore, when two stranded wires are wound around one product bobbin as in Example 2, the work of replacing the supply bobbin during use by the user is reduced to 1/2.
In addition, the twisted wires of the present invention have excellent effects in manufacturing products such as steel cords, such as the two twisted wires being wound in opposite directions on the left and right, which cancels out the twist when used, making it easier to handle. A line machine is something you have.
