DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to transport a hot-rolled wire and to align the wire without trouble such as hooking and deformation of the wire (centering the wire to be conveyed to the center in the width direction of the transport). The present invention relates to a method and apparatus for conveying a wire rod.

[0002]

2. Description of the Related Art As is well known, in a wire manufacturing process for performing heat treatment on a conveyor immediately after hot rolling, a hot-rolled wire is formed into a ring shape, and the conveyor is spirally formed. In general, they are placed on a flat surface, transported while being subjected to heat treatment, and then converged into a coil package.

However, when the wire ring is deposited in the focusing device, if the wire deposition position is deviated,
There is a high possibility that troubles such as collapse of the load, improper packing appearance, and catching of the ring may occur. Also, there is a method of intentionally dispersing the ring in the circumferential direction in order to reduce the coil deposition height when converging while dropping the ring, but even in that case, the ring supplied to the apparatus is eccentric. In some cases, the same troubles as described above may be caused. These troubles have hindered productivity and reduced the yield, which has been a major operational problem.

[0004] As means for solving this problem, for example, a wire rod transporting device as disclosed in Japanese Utility Model Publication No. Sho 62-5772 is disclosed. The transfer device includes a roller that can move in a direction approaching and separating from the wire on the roller conveyor and rotate at a contact portion with the wire on both outermost sides of the wire on the roller conveyor on which the wire is transferred. It is a device equipped with an aligning tool.

[0005]

[Problems to be Solved by the Invention]
By performing the alignment in the middle of the conveyance by the apparatus disclosed in Japanese Patent Application Laid-Open No. 2-5772, there is a possibility that some deviation during ring deposition may be eliminated. However, even if the transfer device uses a roller conveyor instead of a transfer device having claws such as a chain conveyor, the desired centering amount cannot be obtained due to the weight due to the overlap between the wire rings and the frictional force. If the aligning force is too strong, the wire rod may be deformed.

Also, since the diameter of the ring usually varies, it is difficult to set the interval in the centering device of the type sandwiching from both sides as described above. If the interval is set to a small diameter, a ring having a large diameter is conveyed. In such a case, the wire ring is caught between the rollers, and conversely, if the distance between the rollers is set to be large, there is a problem that a ring having a small diameter is not aligned. On the other hand, if the pressing force is set too strong to align the ring with the increased frictional force due to the overlap, the ring will be deformed, so it is very difficult to set the spacing between the rollers of the aligning tool or the pressing force. is there.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a method and an apparatus for conveying a wire capable of centering and converging a spiral wire ring conveyed by simple equipment without trouble. Is what you do.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a wire conveying apparatus according to an embodiment of the present invention. The figure shows an example of the wire transport device according to the present invention. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is a perspective view.

In a state where the rolled wire is formed in a ring shape and laid flat in a spiral shape, it is conveyed from the right side of the drawing by the chains 6a and 6b on the stealmore conveyor 5.
The roller conveyor 1 is arranged next to the stealmore conveyor 5, and a step is provided on the convergence device side. In this example, a pair of cantilevered conical rollers 2a and 2b are installed on the step portion with their vertexes facing each other. Thereafter, the wire is supplied to the focusing device 8 by the feed conveyor 3.

Due to the step after the roller conveyor 1, the mutually overlapping wires are temporarily suspended in the air, and are released from the restraint by the adjacent rings.
At that time, the wire rod released from the constraint of the adjacent wire rods is placed on the conical rollers 2a and 2b.

By making the rollers 2a and 2b conical, the eccentric side of the wire ring contacts the roller first,
Proceeding in the transport direction and dropping from the roller surface,
With the force acting on the side opposite to the eccentricity, the ring part on the opposite side of the eccentricity eventually comes into contact with the roller, and it becomes a mechanism that drops to the subsequent conveyor in a state where it is balanced at the center of the conveyor by suppressing excessive alignment and naturally, An aligning force corresponding to the amount of eccentricity can be obtained, and the ring is not deformed. In addition, even with a change in the ring diameter, the conical shape is used to balance at a position corresponding to the diameter, so that fine adjustment for alignment is unnecessary.

[0013] Accordingly, the eccentricity of the ring at the converging and dropping port is eliminated, and the deviation of the ring accumulation position is eliminated, so that the collapse of the load, the poor appearance of the package and the trouble of the ring being caught are improved, and the productivity and the yield are improved. Can be achieved.

In the embodiment shown in the drawings, a cantilever conical roller is used. It may be flat, as long as the position where the outside of the wire is placed is inclined. However, in the case of this single-type roller, since the center portion is present, the rear side (stermore side) of the wire ring may ride on the roller and the front side of the wire ring may protrude forward. Need to be careful. In addition, the inclination angle of these roller inclined portions is set to 30 degrees to 40 degrees in order to provide an appropriate centering force and smoothly carry the ring diameter variation.
Degree is desirable.

Further, in the figure, the roller conveyor 1 is arranged immediately before the step. However, when the roller is centered at the step position, it is more likely that there is no restraining force in the conveying width direction on the steermore side. Since the centering can be performed smoothly, the roller type conveyor is preferably used as the conveyor used immediately before the step rather than the chain type conveyor having the claws.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1, 2 and 3, existing equipment is modified, three roller conveyors 1 are installed at the end of a stermore conveyor 5, and at least half of one ring is a stermore conveyor chain 6a. , 6b, and the rear feed conveyor 3 is provided with an inclination of about 8 degrees in consideration of the ability of the ring to go uphill.
It has a step of about mm (The existing equipment was remodeled and a step was made in the middle, so the feed conveyor was inclined upward. In the case of new equipment, no inclination is required.)

The conical rollers 2a and 2b provided at the intermediate position of the step have a diameter of 2 mm because the step is 150 mm.
It is about 50 mm and has a 35 degree inclination. In the embodiment, the chains 4a and 4b are used for the feed conveyor in consideration of the cost reduction of the equipment. However, plates are provided on the upper surface so that they are not hindered by catching during alignment. With the above equipment, alignment of the wire ring with less troubles such as catching is enabled by remodeling inexpensive equipment.
