DISTORTION MEASURING DEVICE FOR ROOF TILE

摘要

PROBLEM TO BE SOLVED: To surely regulate the attitude of a roof tile in a device for measuring the distortion of the roof tile by a sensor while carrying the roof tile to prevent the deterioration of the precision of measurement. SOLUTION: This distortion measuring device for roof tile has a conveyor 12 for supporting the roof tile Wf, the measuring position A of the roof tile Wf being set in the conveyor 12; a plurality of displacement sensors 88 provided above the roof tile Wf in the measuring position A of the roof tile Wf; and a sensor 18 for detecting the advance to the measuring position A of the roof tile Wf in the advancing direction of the conveyor 12. This device further comprises a lifting means 20 for raising and lowering the roof tile Wf on the conveyor 12 by at least three-point support on the lower surface of the roof tile Wf provided in the measuring position A of the conveyor 12, and a positioning means for longitudinally and laterally positioning the roof tile Wf.
