Description

The present invention cleaves terminal of the rolled sheet, to scrap conveying method using a scrap conveying instrumentation 置及 Bikono scrap conveyor to be introduced into the scrap container and transporting the cut pieces of the rolled sheet.

The metal material is generally formed into a plate shape by rolling.
Rolling is a method in which a rolled material is pressed into a thickness direction by passing between a pair of rolls, and is formed into a rolled sheet by extending in a plane direction.
In such a rolling process, the phenomenon that the terminal of the obtained rolled sheet becomes an arc shape in a plan view or a state in which the mouth is cracked in a side view is observed. In particular, when the rolled material is reciprocated and reverse rolling is performed by repeatedly passing between a pair of rolls, such a cracking phenomenon of the rolled plate material becomes remarkable.
For this reason, the rolled plate material obtained by the rolling process is usually subjected to the next step after its end is cut by a shearing device and its end is shaped. On the other hand, the end of the rolled sheet material (cut piece: scrap) is transported by a conveyor on a path different from the path for transporting the metal plate, and then scraped down from the conveyor using a jig, and inside the scrap box. It is stored in.
