Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metal strip formed by dividing a rolled metal material such as a rolled steel material in the width direction using a slitter or the like and winding a metal strip into a coil. This paper relates to an apparatus for removing the inner layer of a metal strip coil.

(Conventional technology) A rolled metal material is processed to its final width using a slitter etc.
It is wound into a drum and shipped as a metal strip coil.

Because the inner end of the metal strip is gripped by the drum when winding the metal strip onto the drum to obtain this metal strip coil.

This inner edge tends to break, and the innermost layer of the coil gets scratched when the metal strip is wrapped around the drum and removed from the tram. Therefore, the inner end and at least the innermost layer of the metal strip coil are required to be removed from the coil body of the metal strip coil before shipping.

In the prior art, the inner end of the metal strip coil and the innermost layer of the coil were manually removed from the coil body by an operator and cut with a cutter.

[Invention or problem to be solved]

As described above, the conventional technology requires the manual labor of the operator to remove the coil inner layer of the metal strip coil, resulting in low work efficiency and the metal strip coil being formed by slitting and drum winding of rolled metal material. Although it is possible to automate processes such as hand hanging, weighing, and pallet stacking after processing, only the inner layer removal work of the metal strip coil can be automated, which makes it impossible to perform a series of metal strip processing operations continuously. There was.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inner layer removing device for a metal strip coil that can avoid the above-mentioned drawbacks and mechanically and efficiently remove the inner end of the metal strip coil and at least the innermost layer of the coil. .

(Means for Solving the Problems) One solution of the present invention is that the metal strip coil is bent between the inner end and the innermost layer of the coil. A sorting tool is used to displace the inner end of the coil inwardly so as to separate it from the innermost layer of the coil. A means for sorting the coils, an inner layer gripping/extracting means for gripping the innermost layer of the coils thus sorted and extracting them from the coil body of the metal strip coil, and an inner layer gripping/extracting means for grasping the innermost layer of the coils thus sorted and extracting the innermost layer of the coils from the coil body. a cutting means for cutting the metal strips between the coil body and the coil body to remove the innermost layer of the coil from the coil body; a driving unit for driving the sorting means, the inner layer gripping/extracting means, and the cutting means in a predetermined order; The inner layer of the metal strut coil, which is characterized by having an armored 7. Between the fixative liquid stand on which the strip coil is placed and the inner end of the bent coil of the metal strip and the innermost layer of the coil (1), insert this inner end from the innermost layer of the coil. r Displaced inward in the opposite direction - The sorting with a rod has a jig, and the sorting with 6 - makes the jig go around at least about one time, so that at least the innermost layer of the coil is adjacent - - separated from the next coil layer 1 a sorting means for sorting the coils in this manner, and an inner layer for grasping the innermost layer of the coils thus divided and extracting them from the coil body of the metal ribbed coil.

The coil is heated between the extraction stage, the innermost layer of the coil extracted from the main body, and the human body.
