The present invention relates to a rolling coil specimen collection device, and more particularly to a rolling coil specimen collection device capable of automatically performing the sampling of the rolled coil wound on the mandrel.

The rolled coil finally wound on the mandrel is cut into scraps of corrugated ends before wrapping (by banding), and specimens are taken to perform biopsy or various tests.

By cutting the scrap and collecting specimens as described above, there are the following problems by relying on manual labor.

Since the operator collects specimens for scrap cutting and testing and analysis of the coiled coil end by using gas torch, the occurrence of safety accidents during the falling of the cut and collected scraps and specimens is high. It is true.

In particular, when scraps and specimens are collected, the worker moves in the width direction of the rolling coil and cuts it, thus making it impossible to cut and collect in a uniform state.
