The present invention relates to an automatic stacking device for rolling rolls, and more particularly, to automatically stack a plurality of rolling rolls to improve work efficiency as well as to quickly withdraw the selected rolling rolls, thereby dramatically reducing the working time. It relates to an automatic stacking device for rolling rolls to shorten.

In general, the rolling roll is installed in a rolling mill for producing a cold rolled steel sheet to produce a cold rolled steel sheet of various specifications by adjusting the feed rate and reduction rate of the steel sheet (slab).

These rolling rolls are classified into work rolls and back up rolls according to the purpose and purpose of use. Especially, the rolling rolls are periodically polished according to the production volume and working time of the cold rolled steel sheet. Will improve.

To this end, conventionally, rolling rolls waiting to proceed with polishing operations and rolling rolls for which polishing operations are completed are stored through a storage device, which is a separate storage space. In particular, a soft support pad is placed between rolling rolls that are sequentially stacked. Insertion is to prevent in advance the breakage and damage of the rolling rolls that may occur while being in close contact with each other.

However, in the related art, the operator has to manually insert the supporting pads between the rolling rolls, thereby having an inefficient closed end in which the stacking efficiency of the rolling rolls is determined according to the skill of the operator.

In addition, there is a serious problem that a safety accident occurs due to the falling of the heavy rolling rolls in the process of inserting the support pad by hand between the loading device and the rolling rolls with a narrow working space.

Therefore, in recent years to solve the above problems,

Patent No. 0516522 entitled "Roll Lapping Device" comprising a second link member which has a contact pad and allows the movement of the backing pad side of the backing space upon roll deposition.

However, the conventional "roll stacker" has to lift the rolling rolls stacked on the top in order to take out the rolling rolls deposited on the bottom, thereby resulting in limitations in use due to the hassle and inconvenience of the drawing operation.

In particular, in the conventional "roll stacking device", in order to pull out the rolling roll deposited on the lower part, the worker has to lift the rope connected to the hoist on both sides of the rolling roll deposited on the upper part, and as a result, the pulling out of the rolling roll is delayed as a whole. As a result, the productivity is lowered.

In addition, the conventional "roll stacking device" has a disadvantage in that the worker has to connect the ropes on both sides of the rolling roll in order to draw out the rolling rolls deposited on the lower part, which necessitates a large number of workers, which increases the labor cost. It became.

In addition, the conventional "roll stacking device" simply does not suggest a way to efficiently manage the rolling rolls according to the processing and storage conditions of the rolling rolls, so that accurate management and utilization of the rolling rolls is impossible. There is a problem that the efficiency and range of application is extremely limited.

Therefore, it is possible to automatically draw out a large number of rolling rolls to improve the loading and working efficiency, as well as to efficiently manage the rolling rolls according to the processing and storage conditions of the rolling rolls to maximize the utilization range of the rolling rolls. The accumulator is more urgently needed than ever.
