Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to a double-twisting machine for twisting a plurality of filaments together.

B. Prior art A conventional double-twisting wire twisting machine, for example,
As stated in No. 19050, the structure is as shown in Figure 3. In other words, there is a hollow bow 3 and a bow 3' placed at a symmetrical position to balance the rotation.
A cradle 4 rotatably supports the hollow shafts 2 by bearings 11, and is always stationary in space at the center of the hollow shafts 2.
It has a structure in which a winding bobbin 7 is attached to the winding bobbin 7. A plurality of supply wires 1 enter from one end of the rotating hollow shaft 2, move in the direction of the arrow in the drawing, and pass through the guide rollers 12, 13.
It is guided into the interior of the rotating bow 3 through the. At this time, the stranded wire 9 is twisted once and twisted once in part B of the drawing.
becomes. This stranded wire 9 is pulled out from the other end of the bow 3 through guide rollers 14 and 15 from another hollow shaft 2 by a capstan 5 in the cradle 4, during which a second twist is applied in part A of the drawing. The twisted wire 8 is twisted twice, and is wound onto a winding bobbin 7 through a guide roller 6. 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. Further, the winding bobbin has the drawback that only one strand of wire can be wound thereon, and a product in which two strands of wire are simultaneously wound on the bobbin cannot be manufactured.

D. Means for Solving the Problems This invention provides the same bow as the bow 3 of the conventional wire twisting machine on the opposite side, and supplies a plurality of strands from both sides of the rotating body, that is, the front and back two locations, and The disadvantages of the conventional wire twisting machine are solved by guiding the wire through a bow into a cradle and winding it onto a winding bobbin.

E. Example 1 FIG. 1 is a front view showing an example of the present invention.
Two hollow bows 3 located opposite two hollow shafts 2, 2' with guide rollers 12, 14
The main body connected by the bearings 1 on both sides can rotate freely.
1, and the bow 3 is provided with guide rollers 13 and 14. A cradle 4 which is always stationary with respect to space is provided inside the main body, and a capstan 5 and a winding bobbin 7 are attached to the cradle.

To use this wire twisting machine, the wires are pulled out from a plurality of single wire bobbins 10 on both sides of the machine, drawn into the machine from the ends of the hollow shafts 2 and 2' on both sides, and passed through the guide rollers 12 and 13. The guide rollers 14 and 15 are guided from the inside of the bow 3.
It enters the hole in the hollow shaft 2', 2 on the opposite side and is pulled out from both sides of the cradle 4 through the hole. At this time, the strands are twisted once on the inlet side to form a single-twisted strand 9, and then twisted once on the exit side to form a twice-twisted strand 8. The stranded wire 8 is drawn out by the capstan 5 and wound onto a winding bobbin 7.

According to this wire twisting machine, two twisted wires twisted twice per rotation of the bow can be simultaneously twisted together and wound onto a single winding bobbin. The twisted wires that have been wound up become twisted wires in which the twisting direction is opposite to the right direction and the left direction.

Embodiment 2 FIG. 2 shows another embodiment of the present invention. The general structure of this embodiment is the same as that of the first embodiment, but in this embodiment, two winding bobbins 7, 7' are provided inside the cradle 4.

As in the first embodiment, the strands are fed from both sides of the machine, pass through the bows 3 on both sides, and are pulled out into the cradle 4 by two sets of capstans 5.
The film is wound onto winding bobbins 7 and 7', respectively.

With this wire twisting machine, two twisted wires can be manufactured by winding them onto respective bobbins at the same time.

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 usually installed on the opposite side to balance the bow. The wire twisting machine of the present invention can produce twice as many twisted wires with the same power as the conventional one, resulting in savings in power costs. Furthermore, when two stranded wires are wound on one product bobbin as in Example 1, the work of replacing the supply bobbin when used by the user is halved, and the two stranded wires The wire twisting machine of the present invention has an excellent effect such that the directions are opposite on the left and right sides, and when the wire is used, the twisting is canceled out and handling becomes easier.
