Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing guide device.

[0002]

2. Description of the Related Art Generally, since a filamentous body is a long product, manufacturing, storage, transportation, and trading are carried out in the form of a package wound on a bobbin or a drum.

Also in the production of a twisted wire, a wire wound on a bobbin is used as an element wire to be twisted. Then, in the twisting work, each of the plurality of wire winding bobbins is pulled out and sent to the twisting machine,
It is manufactured as a twisted wire by twisting it with the twisting machine.

[0004] In the work of sending out such a wire, it is essential that a plurality of wires are sent out smoothly and at the same tension level.

However, it is customary that the winding lengths and winding tensions of the wires of the plurality of wire-winding bobbins are different, and the remaining amount of winding is also different. For this reason, in such twisting work, it was extremely difficult to send it out with a constant tension without slack.

FIG. 4 is a front view showing a conventional wire feeding device.

In FIG. 4, 1 is an arm, 2 is an arm ring, 3 is a bobbin, 4 is a wire, 10 is a rotating shaft, 11 is a balancer, and 12 is a floor.

As can be seen from FIG. 4, a wire 4 is wound around the body of the bobbin 3, and the wire winding bobbin 3 formed by winding the wire 4 is placed on the floor 12. . In FIG. 4, the conventional wire feeding device is installed above the wire winding bobbin 3.

That is, the conventional wire feeding device is equipped with a rotating portion 10 that rotates under a constant torque brake, an arm 1 fixed to a side surface portion of the rotating portion 10, and an arm 1 at the tip thereof. It comprises an arm ring 2 and a balancer 11 fixed to the side surface of the rotary unit 10 at a position facing the fixed position of the arm 1.

Here, the wire 4 is passed through the arm ring 2, and the arm 1 to which the arm ring 2 is fixed.
The wire 4 is pulled out from the body of the bobbin 3 by rotating the.

The drawn wire 4 is sent to a twisting machine (not shown).

However, in the conventional wire feeding device,
As described above, the rotating unit 1 that rotates under the constant torque brake
The wire 1 is pulled out while the arm 1 fixed to the side surface of the rotating portion 10 through 0 and the arm ring 2 installed at the tip of the arm 1 rotate to pull out the wire 4. If the amount is large, there is no resistance to the decrease in the drawing tension.

Further, since the winding force of the wire 4 around the bobbin 3 is weak from the beginning, the wire 4 is loosened when the wire 4 is pulled out, and the arm 1 is overrun when the wire feeding operation is interrupted. However, there was a drawback that the slack in the wire was caused by.

Moreover, when the conventional wire-sending device is pulled out from the upper part to the lower part, or when the wire 4 wound around the bobbin 3 is loosened, the winding is easily collapsed or the wires 4 cross each other.

When such winding collapse or crossing between the strands 4 occurs, the strands 4 often have a V-shaped bent portion, a loop-shaped curl, a wire break, or the like.

[0016]

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and its object is to solve the above-mentioned drawbacks of the prior art and to prevent the slack of the wire. An object of the present invention is to provide a wire feeding device capable of sending a wire from a wire winding bobbin.

[0017]

The gist of the present invention is to provide a wire having a rotating part, an arm fixed to the side surface of the rotating part, and an arm ring installed at the tip of the arm. An element wire drawing guide device capable of drawing an element wire from a winding bobbin, wherein a floating weight having a passage hole through which the drawn element wire can pass is provided between the arm ring and the element wire winding bobbin. There is a wire drawing guide device.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a wire drawing guide device of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing a state in which a strand wire drawing guide device of an embodiment of the present invention is installed on a strand wire winding bobbin and a strand wire is pulled out.

FIG. 2 is a front view of the floating weight, and FIG. 3 is a side view thereof.

1 to 3, 1 is an arm, 2 is an arm ring, 3 is a bobbin, 4 is an element wire, 5 is an element wire immediately after being separated from the winding cylinder, 6 is a floating weight, and 7 is a weight main body. , 8 is a die part, 9 is a passage hole, 10 is a rotating shaft, 11 is a balancer, and 12 is a floor surface.

As can be seen from FIG. 1, the strand wire drawing-out guide device of one embodiment of the present invention has a floating weight 6 having a passage hole through which a strand wire 5 drawn between an arm ring 2 and a strand wire bobbin can pass. Is provided.

Here, the floating weight 6 is composed of a weight main body portion 7, a die portion 8 and a passage hole 9 as can be seen from FIGS.

The weight main body portion 7 of the floating weight 6 is made of a soft material that does not cause external damage even if it contacts the wire 4, and the die portion 8 is a super hard die which is not easily worn even when the wire 4 passes. Manufactured from metal or diamond.

As described above, in the element wire drawing-out guide apparatus according to the embodiment of the present invention, the floating weight 6 that floats the element wire 5 drawn from the element wire winding bobbin between the arm ring 2 and the element wire winding bobbin.
Since the wire 5 is passed through the passage hole, it is possible to always apply a constant tension to the wire 5, and as a result, it is possible to effectively prevent the slack of the wire 5 from being generated. Even if a cross or the like occurs between the wires 4, it is possible to completely suppress the V-shaped bent portion, the loop-shaped curl, and the disconnection of the wire 4.

Moreover, the floating weight 6 used in the present invention is inexpensive because it has an extremely simple structure, and the workability of passing the wire is also excellent.

[0027]

Industrial Applicability According to the present invention, the element wire drawing guide device can always apply a constant tension to the element wire, and as a result, it is possible to effectively suppress the occurrence of slack in the element wire. Even if the wire is collapsed or the wires cross each other, the V-shaped bent portion of the wire, the loop-shaped curl, and the wire break can be completely suppressed, which is industrially useful.
