Title:
SIDE TRIMMER PART STEEL BAND PASSING POSITION CONTROL METHOD
Document Type and Number:
Japanese Patent JP3199157
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the quality of steel band edge part from being deteriorated after side trimming by meandering the steel bands beforehand according to the amount of deviation of the center of the weld part by a centering device so that the locus of an edge becomes equal between the preceding and latter materials when a weld part passes through a side trimmer.
SOLUTION: A center position control part 5 integrates a deviation between the detected value of the amount of meandering from a meandering detector and a control target value proportionally when a weld part arrives at the front of a steering roll 8 so that the amounts of meandering of steel bands 1, i.e., the amounts of trimming of the preceding and latter materials 14 and 15 are equal to each other when the weld part passes through a side trimmer 3. Also a deviation between the obtained value and a positional detected value of a hydraulic cylinder 10 is integrated proportionally, and the results are output to the operating part 9 of the steering roll 8. By this, the hydraulic cylinder 10 is operated to incline the steering roll 8 to a pass line, and meanders the steel bands 1 beforehand so that the amount of deviation of the center of the steel bands 1 becomes the amount of trimming when the weld part passes through the side trimmer 3.
