Description

Wire coil stacking device and wire coil stacking method

The present invention relates to a wire coil stacking device and a wire coil stacking 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 the laying head, which is conveyed while being unfolded on the conveyor, and is accumulated in the coil accumulation device.
As a conventional coil stacking device, there is known a device that stacks introduced wire rod coils without causing flaws in the inner diameter of the coil (for example, Patent Documents 1 and 2).

The coil accumulating device of Patent Document 1 includes a stem bottom body, a stem formed by erecting a plurality of rod-shaped bodies from the stem bottom body, and a rod-shaped stem extending up and down from the stem bottom body. a lifting sail projecting from between the bodies. Then, the inner diameter portion 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 in the wire coil. .

In addition, the coil stacking device of Patent Document 2 has an entry-side guide provided with an upper guide segment and an intermediate guide segment, and a nosecone attached to the upper end, so that the nosecone is positioned at the center position of the entry-side guide. It comprises a movably arranged core member, a coil outer diameter guide rod that can move radially around the core member, and a coil plate that moves up and down with the core member loosely inserted. A wire rod dropped from the conveyor is regulated on the inner diameter side of the coil by the nose cone, and regulated on the outer diameter side of the coil by the upper guide segment and the middle guide segment of the entry guide. By entering and stacking on the coil plate, the wire rod coil is stacked on the coil plate in a stable manner without causing scratches.

JP-A-2001-10767 Japanese Utility Model Laid-Open No. 03-126217

By the way, in the coil accumulating device of Patent Document 1, the coil inner diameter portion of the wire rod coil dropped from the conveyor continuously contacts the stem, so that a worn portion may be generated, and the worn portion may be deformed and burr may be generated. . If the wire coil stacking operation is performed in a state where the stem has burrs, the falling wire coil may come into contact with the burrs and the inner diameter of the coil may be damaged. Also, when the wire coil is pulled out from the stem, the coil inner diameter portion of the wire coil is caught by the burrs of the stem, and the wire coil cannot be pulled out normally from the stem.

Also, in the coil stacking device of Patent Document 2, a portion of the wire rod coil falling from the conveyor continuously contacts the core member, which causes an abrasion portion, and the abrasion portion may be deformed to generate burrs. . Thus, if the wire coil stacking operation is performed in a state in which burrs are generated on the core member, the falling wire coil contacts the burrs of the core member, causing scratches on the inner diameter of the coil. Also, when the wire coil is pulled out from the core member, the coil inner diameter portion of the wire coil is caught by the burrs of the core member, and the wire coil cannot be pulled out normally from the core member.

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

The present invention has been made by focusing on the above-mentioned unsolved problems of the conventional example, and integrates high-quality wire rod coils that do not cause scratches on the inner diameter of the coil while reducing the repair cost of the sail lift. It is an object of the present invention to provide a wire coil stacking device and a wire coil stacking method.

In order to achieve the above object, a wire coil stacking apparatus according to an aspect of the present invention includes a chamber into which a wire coil conveyed in a ring shape is introduced from above, and a A nose cone through which the wire coil is passed from the top, a coil plate that is vertically arranged in the chamber and collects the wire coil that has fallen from the nose cone, and a vertical direction extending between the lower part of the nose cone and the coil plate. and a sail lift that guides the coil inner diameter portion of the wire rod coil falling from the nose cone, the sail lift including a core material, a surface material detachably fixed to the core material, It has

Further, a wire coil stacking method according to an aspect of the present invention is a wire coil stacking method using the wire coil stacking apparatus described above, wherein the falling wire coil comes into contact with the inner diameter portion of the coil, causing the lift surface of the surface material to In this method, when damage occurs, at least the damaged surface material is removed from the core material, and a new surface material is attached to the core material. Here, the term "damage" refers to wear or the like caused by continuous contact between the coil inner diameter portions of the wire coil.

According to the wire coil stacking device and the wire coil stacking method according to the present invention, it is possible to reduce the repair cost of the sail lift and stack high-quality wire coils that do not cause scratches on the inner diameter of the coil. can.
