Description

The present invention relates to a wire rod coil accumulating device and a wire rod coil accumulating method.

In the wire rod coil production line, the wire rod rolled by the wire rod rolling mill is formed into a continuous ring-shaped wire rod coil by a laying head, and is conveyed while being developed on a conveyor and integrated in a coil integrating device.
As a conventional coil integrating device, a device that integrates the introduced wire rod coil without causing a flaw in the coil inner diameter portion is known (for example, Patent Documents 1 and 2).

The coil integrating device of Patent Document 1 has a stem bottom body formed by erecting a plurality of rod-shaped bodies from the stem bottom body inside a tubular body, and a rod-shaped stem that moves up and down from the stem bottom body. It has an elevating sail that protrudes from between the bodies. Then, the inner diameter of the wire coil that has fallen from the conveyor is inserted into the stem, and the elevating sail that moves up and down from the stem bottom is accumulated on the stem bottom without causing scratches or bending on the wire coil. ..

Further, the coil integrating device of Patent Document 2 is equipped with an entry-side guide provided with an upper guide segment and an intermediate guide segment and a nose cone at the upper end so that the nose cone is located at the center position of the entry-side guide. It includes a core member that is movably arranged, a coil outer diameter guide rod that can move in the radial direction around the core member, and a coil plate that moves up and down by loosely inserting the core member. Then, the wire coil that has fallen from the conveyor is regulated on the inner diameter side of the coil by the nose cone, and the outer diameter side of the coil is regulated by the upper guide segment and the intermediate guide segment of the inlet side guide, and between the core member and the coil outer diameter guide rod. By entering and accumulating on the coil plate, it is possible to accumulate on the coil plate in a stable packing form without causing defects in the wire rod coil.

By the way, in the coil integrating device of Patent Document 1, a worn portion may occur when the coil inner diameter portion of the wire rod coil falling from the conveyor continuously contacts the stem, and the worn portion may be deformed to generate burrs. .. If the wire rod coil is integrated while the stem has burrs, the falling wire wire coil may come into contact with the burrs and a flaw may occur in the inner diameter of the coil. Further, when the integrated wire rod coil is pulled out from the stem, the coil inner diameter portion of the wire rod coil is caught by the burr of the stem, and the wire rod coil cannot be pulled out normally from the stem.

Further, in the coil integrating device of Patent Document 2, a part of the wire rod coil falling from the conveyor may come into continuous contact with the core member to generate a worn part, and the worn part may be deformed to generate a burr. .. In this way, if the wire rod coil is integrated with the core member having burrs, the falling wire rod coil comes into contact with the burrs of the core member, and a flaw is generated in the inner diameter of the coil. Further, when the integrated wire rod coil is pulled out from the core member, the coil inner diameter portion of the wire rod coil is caught by the burr of the core member, and the wire rod coil cannot be normally pulled out from the core member.

Therefore, in Patent Document 1, the entire stem is replaced with a new member when a worn portion is generated on the stem, and in Patent Document 2, the entire core member is replaced with a new member when a worn portion is generated on the core member. It is possible to prevent internal defects of the coil or to perform normal extraction from the wire rod coil.
However, the replacement of the entire stem of Patent Document 1 and the replacement of the entire core member of Patent Document 2 significantly increase the cost of member replacement. In addition, since the work time for member replacement becomes long, the maintenance cost also increases.

Therefore, the present invention has been made by paying attention to the unsolved problems of the above-mentioned conventional examples, and is a high-quality wire rod coil in which the inner diameter of the coil is not scratched while reducing the repair cost of the sail lift. It is an object of the present invention to provide a wire rod coil accumulating device and a wire rod coil accumulating method capable of accumulating.

The sail lift 5 can be easily repaired by simply replacing at least one of the divided plates 14a to 14f) and the fourth peripheral plate 15 (divided plates 15a to 15f).

Therefore, in the present embodiment, the entire worn sail lift 5 is not replaced with a new member, and the repair of the sail lift 5 is completed in a short time only by replacing the worn split plate. The repair cost of the lift 5 can be significantly reduced.
Further, a part of the surface material 11 (predetermined division plate) in which wear has occurred can be replaced with a new division plate to repair the sail lift 5, and the surface material 11 of the sail lift 5 has a coil. Even if the coil inner diameter portion of the wire rod coil C immediately before falling onto the plate 8 comes into contact with the coil inner diameter portion, no flaw is generated in the coil inner diameter portion, and a high quality wire rod coil can be integrated.
Then, even when the sail lift is pulled out from the wire coil C transferred onto the bucket 2, the surface material 11 of the repaired sail lift 5 does not have a portion where burrs or the like are caught in the coil inner diameter portion of the wire coil. The sail lift 5 can be normally pulled out from the wire coil C.

However, the present invention is not limited to this, and a plurality of arc-shaped or polygonal plates surrounding the core material 10 in the elongated direction may be used. Further, the first to fourth peripheral plates 12, 13, 14, and 15 are formed of a plurality of rectangular cuboid-shaped divided plates 12a to 12f, 13a to 13f, 14a to 14f, and 15a to 15f having the same shape. The divided plates having different values may be continuous in the long direction of the core material 10. Further, in the sail lift 5 of the present embodiment, as shown in FIG. 3, the core material 10 has a plate-like structure having a pair of short side surfaces 10a and 10b and long side surfaces parallel to each other in the long direction. The gist of the present invention is not limited to this, and various shapes such as a cylindrical shape and a cross section orthogonal to the long direction having an H shape can be applied.
