Description

Coil Sleeve Automatic Separator

The present invention relates to a coil sleeve automatic separation device, and more specifically, to automate the operation of separating the steel sleeve and the scrap wound around the outer diameter portion used for winding the ultra-thin cold rolled steel coil in the cold rolling mill, respectively. The present invention relates to a coil sleeve automatic separation device that can greatly reduce the time and manpower required for separation work and to enhance the separation work.

In each line of a typical cold rolling mill, as the sleeve is wound with a scrap, it is withdrawn from the facility, and the sleeve and the scrap are separated and collected from each other, and then the sleeve is transferred to the sleeve stack for waiting for reuse, and the separated Scrap is enclosed in an auxiliary box with the band wound around its outer diameter and is accompanied by a separation operation for recycling as a raw material of a steel mill.

Such a sleeve is manufactured by rolling an ultra-thin cold rolled steel sheet having a thickness of 0.18 to 0.6 mm and a width of 685 to 980 mm, in particular, a tin-plated disc, in a cold rolling mill in a steel mill, and then rolling out the rolling mill to form a coil at the exit side of the rolling mill. In order to prevent buckling at the inner diameter of the coil, the sleeve is mounted on the mandrel of the coil winding machine and inserted into the inner diameter of the coil. The sleeve is a consumable material formed of an iron material which is separated from the coil when the coil wound up at the entrance side of the electrolytic cleaning facility, the continuous annealing facility, and the continuous plating facility, which is a post-process of the rolling process, is released.

On the other hand, due to the nature of the installation, which is difficult to tension the coil unwound in the installation, the wound coil cannot be released to the entrance side of the installation, so that the scrap, which is a portion of the inner diameter of the coil, is wound around the sleeve. Therefore, in order to separate them from each other, in the past, a sleeve wound with scraps was rolled to the factory floor, and then the sleeve was pulled as a tong tool to separate the scraps, or the scraps were removed from the bottom surface and separated and collected by manpower. There is always a risk of safety accidents due to manual work, a lot of work time, while the work load is heavy.

In addition, as shown in Figs. 1A and 1B, the worker attaches the separating jig 201 and reversely rotates the scrap 2b to separate them, or rewinds the manual scrap (not shown) or manually. Separation device such as a cutter (not shown) was manufactured separately and used for separation work.

Then, the reverse rotation separator 202 was inserted into the inner diameter of the sleeve 2a on which the scraps 2b were wound, and then reversely rotated in the opposite direction of the winding direction using the electric forklift 203, so that the operation was separated. In addition, these separation devices necessarily require a pair of two-person work, the complexity of the work procedure is difficult to improve the work performance, there is a problem that can not improve the work efficiency due to long working time.

Therefore, the present invention has been devised to solve the problems described above, the purpose of which is to remove the scrap wound on the sleeve by using hydraulic power to separate and collect the sleeve wound each other, the wound wound generated in the cold rolling mill By performing the reverse rotation as much as possible and automating the series of operations, it is possible to prevent the worker's safety accidents due to manual operation, reduce the worker's workload, and perform single work alone, and greatly improve the working time. The present invention provides a coil sleeve automatic separation device that can be shortened and can improve work efficiency and rationalization.
