Abstract
PURPOSE: To realize the full number test with a high accuracy on the transfer line of the steel shape by installing three pairs or more of the projectors and receivers on the transfer line and then measuring the bend of the steel shape based on the transfer velocity and the time error obtained by detecting the passing of the steel shape on the transfer line.
CONSTITUTION: Steel shape 1 cut by the saw is transferred to test floor 3 after passing through roller corrector 2 and then carried on floor 3 to the width direction. More than three pairs of detectors 4 consisting of light receiver 4a and projector 4b each are installed on floor 3 at both the upper and lower parts equidistantly and orthogonally to the transfer direction of steel 1. At the same time, transfer velocity detector 5 is attached at the forward position in the transfer direction against detector 4. Thus steel 1 being transferred on floor 3 is detected for the transfer velocity by detector 5, at the same time the time when steel 1 passes through each detector is detected. Based on the detection time error and the transfer velocity, one point detected on steel 1 is set as the standard to obtain other detection point positions. Then the curve formula connecting the detection points is obtained based on the operation formula, thus ensuring the measurement for the bend of steel 1.
