Pass line switching apparatus and the pass line switching method in continuous processing line of metal band

摘要

PROBLEM TO BE SOLVED: To provide a method by which the safety of a manual work is kept and the work is performed in a short time when changing the pass line in the continuous processing line of a metal strip.;SOLUTION: The first wire rope 10 along an approximately horizontal pass and the second wire rope 11 along an approximately vertical pass are stretched and, after separating into a preceding metal strip and a succeeding metal strip by cutting the metal strip, the nose part of the succeeding metal strip is made to hold with the clamp part of a metal strip pulling tool 1, also attracted to the magnet attracting part of the metal strip pulling tool which is connected to the clamp part rotatably by making a metal strip pulling magnet which is hung on the first wire rope to excite and guides to the terminal part of the approximately horizontal pass. The magnet attracting part which is separated by making the pulling magnet demagnetize is attracted to a receiving magnet 7 which is hung on the second wire rope and guides the nose part of the succeeding metal strip to the terminal part of the approximately vertical pass by driving the second wire rope.;COPYRIGHT: (C)2011,JPO&INPIT
