Device for detecting flatness of running plate material

Abstract

Abstract PURPOSE:To know simultaneously the distortions in lateral and longitudinal directions by finding the difference in the detecting values among No. 1 distance detecting means measured from the surface of the plural plate material arranged in the width direction of the plate material between table rollers, and the difference of No. 2 distance detecting means arranged at the prescribed distance in longitudinal direction. CONSTITUTION:Distance sensors 30, 32, 34 are arranged in the width direction of a plate material 10 positioned between table rollers 12, 14 and the distortion shape in width direction of the plate material 10 is detected by detecting the absolute distances a, b, c which are from the fixed height to the surface of the plate material 10. Distance detecting sensors 36, 38, 40 are also arranged at the prescribed distance in the longitudinal direction of the plate material on the same position with the sensors 30, 32, 34 being in the width direction of the plate material between the rollers 12, 14, and the similar distances x, y, z are detected with the same timing as the distances a, b, c and the distortion shape in longitudinal direction is detected from the comparison of the both.
