2. Description of the Related Art A first conventional wire rod laying apparatus (Japanese Patent Application Laid-Open No. 53-85750) includes a plurality of liner members inserted in a butt state inside a laying head pipe which is a continuous pipe that is bent. I'm using The liner member was provided with a nose tapering inward at one end and a mouth expanding outward at the other end. In this apparatus, the plurality of liner members are not connected, and there is no mechanism for rotating the liner members.

A second conventional wire rod laying device (Japanese Patent Laid-Open No. 57-127522) is an improved mechanism of the above-mentioned first conventional wire rod laying device, as shown in FIG. A simple and inexpensive device has been proposed by using a helical spring S inserted and extended in the longitudinal direction instead of a plurality of liner members inserted inside.

[0004] The column of the detailed description of the invention in the above publication showing the second conventional wire rod laying device states that "if a part of the inner surface of the spring is worn by contact with the rolled material,
It is sufficient to rotate the spring in the tube, move the worn portion out of the passage of the rolled material, and bring a fresh portion that has not yet been worn into contact with the rolled material. " However, the claims of the publication do not include a description of a mechanism for rotating the spring.
Further, in this device, since a spring is used instead of the plurality of liner members, there is no description about a connection mechanism for connecting the plurality of liner members.

The third conventional wire rod laying device (JP-A-1-118330 and JP-A-1-288574) has a plurality of simple annular members having lubricating performance arranged inside a laying head pipe. It is an object of the present invention to solve the problems of the conventional device.

[0006]

In the first conventional wire laying device, the continuous pipe is bent so as to be continuous from the top of the cone to the bottom edge of the cone along the substantially conical slope of the substantially cone. The wire is introduced from the inlet of the continuous pipe while rotating the continuous pipe at high speed around the axis of the cone, and the wire introduced from the inlet of the continuous pipe is continuously coiled. Since the wire is sharply rubbed against the inner peripheral wall of the continuous pipe, there is a problem that the surface of the wire is seized and scratched.

The second conventional wire laying apparatus uses the helical spring S inserted and extended along the longitudinal direction inside the laying head pipe. When S is rotated on the wire entry side or the exit side of the pipe body P, the helical spring S is liable to be twisted, so that the portion worn in contact with the rolled material is replaced with a fresh portion that has not been worn yet. There was a problem that it was difficult to reliably rotate and move.

In the above-mentioned conventional second wire rod laying apparatus, when the inner surface of the spring is worn, if it is worn beyond the radius of the coil diameter, as shown in FIG. Since the contact angle with each of the spiral springs S becomes an acute angle, there is a problem that the wire W is easily damaged. Therefore, the life of the spiral spring is limited to the radius of the coil of the spiral spring. Thus, there is a problem that the life improvement ratio is small.

Furthermore, in the second conventional wire rod laying device, the mechanism for rotating the spiral spring S is not specified.

[0010] Furthermore, the third conventional wire rod laying device described above simply arranges a plurality of annular members each having a hole for supplying the wire rod inside the laying head pipe. There has been a problem that a part of the inner periphery of the annular member is locally worn and needs to be replaced early.

The replacement of the annular member is carried out by removing the laying head main body, taking out about 140 annular members from the inside, inserting a new annular member, and attaching the new annular member to the laying head main body. The annular member is a lubricating material such as carbon fiber, and has a short life and is very expensive. Therefore, it has been desired to improve the life of the annular member from the viewpoint of running costs and man-hours for changing steps.

Therefore, the present inventor has proposed that at least a portion of a pipe body extending and disposed in a guide hole connecting a small-diameter inlet into which a wire is introduced and a large-diameter outlet through which the wire is led. In the above, an annular member formed with an inner peripheral wall portion to which the wire is supplied is rotatably connected so that its axis can intersect, and the annular member is inserted and held in series. In view of the technical idea of the present invention, the rotation of the annular member in at least a part of the pipe body causes the wire supplied in the inner peripheral wall of the annular member to be spirally bent. As a result of further research and development, the annular member is connected so that its axis can intersect freely, so that the swing angle of the annular member can be changed so that the axis of the annular member changes. In the uniform wear of the peripheral wall portion, and extending the life of the annular member, thereby achieving the present invention to achieve the object of reducing the running cost and Dangae steps.

[0013]

According to a first aspect of the present invention, there is provided a wire laying apparatus, wherein the wire laying head pipe rotatably held on a base comprises a wire laying head. A pipe body extending in a guide hole connecting between a small-diameter inlet through which the wire is introduced and a large-diameter outlet through which the wire is led, and an inner peripheral wall portion to which the wire is supplied is formed. An annular member that is rotatably connected so that the shafts can intersect and that is inserted and held in series in at least a part of the pipe body, and imparts rotation to at least a part of the pipe body and imparts rotation to the annular member. And a rotating mechanism for spirally bending the wire supplied inside the inner peripheral wall.

[0014]

The wire laying device according to the first aspect of the present invention having the above-described structure is provided in a guide hole connecting a small-diameter inlet into which a wire is introduced and a large-diameter outlet through which the wire is led. In at least a part of the extended pipe body, an annular member having an inner peripheral wall portion to which the wire is supplied is rotatably connected so that its axis can cross freely, and the annular member is inserted and held in series. The rotation mechanism imparts rotation to the annular member in at least a part of the pipe body, whereby the wire supplied in the inner peripheral wall portion of the annular member is bent spirally, so that the annular member is rotated. Since the shafts of the members are connected so as to be able to intersect with each other, a swing in which the crossing angle of the shaft of the annular member is changed is enabled, and the wear of the inner peripheral wall portion of the wire and the annular member is made uniform, and the ring is formed. It improves the life of the members, an effect of reducing the running cost and Dangae steps.

Claims (1)

[Claims] In a wire laying apparatus, a wire laying head pipe rotatably held on a base is provided between a small-diameter inlet through which the wire is introduced and a large-diameter outlet through which the wire is led. A pipe body extending in a guide hole connecting the first and second pipes, and an inner peripheral wall portion to which the wire is supplied is formed, the shaft is rotatably connected to be able to cross freely, and inserted and held in series in at least a part of the pipe body. And a rotation mechanism that applies rotation to at least a part of the pipe body, applies rotation to the annular member, and bends the wire supplied in the inner peripheral wall into a spiral. A wire laying device characterized by the above-mentioned.
