Title:
DEVICE FOR DETECTING WARPING OF STEEL PLATE
Document Type and Number:
Japanese Patent JP3358708
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for detecting warping of steel plate, wherein the amount of warping of steel plate is detected with a simple configuration and with sure.
SOLUTION: A plurality of sensors for detecting fact of passage of a steel plate 1 are provided on the upper side of a pass line P, and, relating to the detection with the plurality of sensors, detection heights L1-L5 from each pass line are different while detection positions 3c-7c with each sensor are set tilted by 45° from the direction orthogonal to horizontal transportation direction H of the steel plate 1. In addition, a warping calculation means which obtains the amount of warping of the steel plate 1 based on the inspection signal about fact of passage from the plurality of the sensors is provided.
