Description

Rolling Roll Packing Machine {Apparatus for packing press roll}

The present invention relates to a rolling roll, and more particularly to a rolling roll packaging apparatus for packaging a rolling roll for storage of the rolling roll.

In general, the rolling rolls used for cold rolling are required to properly manage the roll surface to ensure product quality of the steel sheet produced by rolling.

In order to supply cold rolling rolls with various roll surface roughness to each line in a timely manner, the rolls must be ground and stored for a long time. To prevent rust caused by long-term storage of the rolls, packaging work should be carried out after grinding rolls. .

Rolling roll packaging operation in the conventional roll grinding machine guides the polished roll to the packing pile with a ceiling vaporizer, and the worker performs the packaging operation manually.

Therefore, in the roll polishing machine, the work process is increased by the roll packing work according to the manual work, which hinders the roll productivity, and the manpower is required for the packing work, thereby causing the inefficiency of the work.

In addition, if the packaging operation is delayed after polishing, the surface of the roll may be damaged due to various foreign matters, resulting in poor quality.

The present invention has been proposed to solve the above problems, and to provide a rolling roll packaging apparatus capable of mechanically packing a rolling roll instead of being manual.
