Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a profile wire twisting device used for manufacturing a locked coil rope by twisting profile wires having a Z-shaped cross section.

[0002]

2. Description of the Related Art The structure of a conventional twisting device for twisting deformed wires is shown in FIG. 5, in which reference numeral 1 is a true circular voice, and 2 and 3 are wiring boards. In the wiring boards 2 and 3, a through hole 4 is formed at the center, and a large number of guide holes 5 are evenly formed on the same circumference around the through hole 4.

Further, a pair of rolls 6 is provided on one side of each of the wiring boards 2 and 3 so as to correspond to each of the guide holes 5. These roll pairs 6 are composed of a pair of rolls 7 that are in contact with each other and rotate. As shown in FIG. 6, notched grooves 8 are continuously formed on the circumferential surface of the rolls 7 along the circumferential direction thereof. The Z-shaped spaces corresponding to the cross-sectional shape of the irregular line a are formed inside the cutout grooves 8 by facing each other.

When twisting the deformed wire a, the core rope A, which has been twisted in a predetermined twisted structure in advance, is passed through the through holes 4 of the wiring boards 2 and 3 into the true circular voice 1 and each deformed wire a is It passes through each guide hole 5 of each wiring board 2 and 3 between the notch grooves 8 of each roll pair 6, and further, these irregular lines a are introduced into the perfect circular voice 1 to be arranged on the outer periphery of the core rope A. .

In such a state, while rotating the wiring boards 2 and 3 in one direction, the core rope A and each irregular line a
Is taken at a constant speed in the direction of the arrow. Rotation of each profile line a around the axis thereof is restricted by the notch groove 8 of the roll pair 6, and therefore the rotation of the wiring board 3 causes the roll pair 6 to rotate.
And the true-shape voice 1 are twisted, the irregular-shape line a is sequentially twisted into the true-circle voice 1. As a result, the irregular-shape lines a are twisted around the outer periphery of the core rope A closely adjacent to each other at a constant pitch. To be combined.

[0006]

However, in such a conventional twisting device, since a pair of rolls is provided on the wiring board to twist the deformed wires, the structure is complicated and expensive. However, since each roll pair has a certain size, the number of roll pairs arranged on the wiring board is limited, and as a result, the number of deformed wires to be twisted is limited.

For this reason, when the roll pair is made compact, the strength is insufficient and the roll pair cannot withstand long-term use, and the arrangement and orientation of the rolls forming the roll pair are deviated so that the irregular line a cannot be obtained. If an external force is applied, the roll pair may be damaged or the deformed line may be deformed or damaged.

The present invention has been made by paying attention to such a point. The object of the present invention is that the structure is simple and the cost can be reduced, and a large number of irregular lines can be smoothly formed if necessary. Another object of the present invention is to provide a twisting device for deformed wires that can be twisted properly.

[0009]

In order to achieve such an object, the present invention provides a rotatable wiring board in which a large number of fitting grooves capable of fitting irregular shaped wires are uniformly formed on the outer peripheral edge. Provided on the center of rotation of the wiring board is a true circular voice with a certain distance from the wiring board, and a core rope is passed through the true circular voice to form a large number of irregular shapes in the fitting groove of the wiring board. The wires are fitted through the wires, these irregular wires are introduced into the perfect circular voice and placed on the outer circumference of the core rope, and in this state, the irregular wires and the core rope are taken out in one direction while rotating the wiring board. By this, each odd-shaped wire is twisted around the outer circumference of the core rope through a true circle voice.

[0010]

[Function] Each deformed wire is restrained from rotating about its axis by being fitted in the fitting groove of the wiring board, so that the rotation of the wiring board causes each deformation between the fitting groove and the perfect circular voice. As the wires are twisted, they enter the circular voice one by one, whereby the deformed wires are twisted tightly adjacent to each other on the outer circumference of the core rope at a constant twist pitch.

Since it is not necessary to provide a roller pair on the wiring board as in the prior art, the structure is simple and inexpensive, and a simple fitting groove is only required to be formed on the outer peripheral edge of the wiring board. Compared to the case, a large number of fitting grooves can be densely arranged on the wiring board, and as a result, a large number of deformed wires can be arbitrarily twisted, and the deformed wires can be kept constant. Since it only travels in the fitting groove of the shape, the deformed wire can always be smoothly and properly twisted without causing damage such as deformation or damage to the deformed wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the drawing, 10 is a true circular voice, 11 is a wiring board for twisting, and 12 is a wiring board for guiding. A twisted wire a having a Z-shaped cross section is fitted to the periphery of the wiring board 11 for twisting. A large number of possible fitting grooves 13 are evenly formed.

As shown in FIG. 3, a step portion 14 corresponding to the side shape of the irregular shape line a is formed on the groove bottom of the engaging groove 13, and when the irregular shape line a is inserted into the engaging groove 13. The side surface of the stepped portion 14 is fitted to the stepped portion 14 so as to be matched.

As shown in FIG. 4, the fitting groove 13 has an axial direction inclined with respect to the axial direction of the wiring board 11 for twisting by an angle of θ corresponding to the twisting angle of the deformed wire a. There is.

Wiring board 11 for twisting and wiring board 12 for guiding
Are connected to each other by a plurality of shafts 15, and a diaphragm ring 16 is provided between the wiring board 11 for twisting and the wiring board 12 for guiding. The diaphragm ring 16 is arranged in the axial direction via the shaft 15. It is slidably supported.

Through holes 17 and 18 are formed in the center of the wiring board 11 for twisting and the wiring board 12 for guiding, and the wiring board 12 for guiding has the same circumference around the through hole 18. A large number of guide holes 1 through which the deformed wire a can be inserted
9 are evenly formed.

The wiring board 11 for twisting and the wiring board 12 for guiding are integrally and rotationally driven in one direction by a driving mechanism (not shown), and the perfect circular voice 10 is on the center line of rotation thereof. It is provided at a position spaced apart from the wiring board 11 for twisting by a certain distance.

When twisting the odd-shaped wire a, the core rope A previously twisted in a predetermined twist structure is passed through the through hole 18 of the guide wiring board 12 and the through hole 17 of the twisting wiring board 11. Guide holes 19 of the wiring board 12 for guiding the required number of irregular lines a evenly.
Through the inner circumference of the throttle ring 16 and then through the fitting groove 13 of the wiring board 11 for twisting to fit them. Then, each deformed line a drawn out from each fitting groove 13 is introduced into the perfect circular voice 1 and arranged on the outer circumference of the core rope A.

In such a state, the twisted wiring board 11 and the guiding wiring board 12 are integrally rotated in one direction, and the core rope A and each profile line a are drawn at a constant speed in the arrow direction. .

By fitting the deformed wires a into the fitting grooves 13 of the wiring board 11 for twisting, the rotation of the wiring board 11 around the axis thereof is restricted. Therefore, the fitting groove 13 is rotated by the rotation of the wiring board 11. And each of the deformed lines a are twisted between the curved line 1 and the perfect circular voice 1 and sequentially enter the perfect circular voice 1, whereby the deformed lines a are closely adjoined to each other at a constant pitch on the outer circumference of the core rope A. Twisted together.

The distance L1 between the true circle voice 1 and the wiring board 11 for twisting corresponds to one pitch of the twist, and the distance L0 between the true circle voice 1 and the fitting groove 13 is 1 thereof. The length of the deformed wire a twisted between the pitches. Therefore, the relationship between the moving speed of the deformed wire a by taking it out and the rotation speed of the wiring board 11 for twisting is that the deformed wire a moves a distance L0. The wiring board 11 for twisting has a relation to make one rotation during this, so that the deformed wire a is twisted by one rotation (one pitch) in the axial direction in the section of L0, and this twisting Deformed wire a is tightly twisted around the outer circumference of the core rope A at a predetermined pitch.

The fitting grooves 13 of the wiring board 11 for twisting are arranged on the circumference of the diameter D1, and the guide holes 19 of the wiring board 12 for guiding are arranged on the circumference of the diameter D2. The inner diameter of the diaphragm ring 16 provided between the wiring board 11 for twisting and the wiring board 12 for guiding is D3, and the relationship between these dimensions is D1 = D2, D3 = D1 × 0.80.

Therefore, in the section from the guide wiring board 12 to the twisting wiring board 11, each irregular line a is squeezed inward through the diaphragm ring 16 and bent in a meandering shape,
In this state, each profile wire a travels sequentially to the side where the wiring board 11 for twisting is arranged while maintaining a constant tension, and therefore each profile wire a is shaped into a predetermined shape in this section, that is, twisted in a spiral shape. A habit of turning is imparted, and by this shaping, each deformed wire a is evenly adhered to the outer circumference of the core rope A and the loosening after twisting is surely prevented.

The distance between the wiring board 11 for twisting and the diaphragm ring 16 is L2, and the wiring board 12 for guiding and the diaphragm ring 16 are
When the distance to and is L3, usually 2L2 =
It may be set to about L3, but when adjusting the shaping strength, the adjustment can be easily performed by moving the diaphragm ring 16 along the shaft 15 to change the distance relationship between L2 and L3. It is possible to

In the twisting device having such a structure, it is not necessary to provide the wiring board 11 with the conventional roller pair, and therefore the structure is simple and inexpensive. Since it is only necessary to form the simple fitting groove 13 on the outer peripheral edge of the wiring board 11, a large number of fitting grooves 13 can be densely arranged on the wiring board 11 as compared with the case of the roll pair. As a result, the number of deformed wires a to be twisted can be significantly increased, and the deformed wire a has a uniform fitting groove 1
Since it only travels inside 3, there is no risk of damage such as deformation or breakage to this irregular wire a, and therefore it is possible to always twist the irregular wire a smoothly and properly.

[0027]

As described above, according to the present invention,
There is an advantage that the structure is simple and can be constructed at a low cost, and a large number of deformed wires can be twisted smoothly and properly as needed.
