Unevenness detector for stacks of objects, e.g. stacks of paper card, corrugated cardboard sheets, etc., measures unevenness in millimeters and determines if surface is concave, convex, S-shaped, etc.

摘要

The stacks of objects are scanned by a focussed beam from a device on a robot arm as the stacks pass under the robot arm. The beam reflection data is fed to a computing device which indicates unevenness in millimeters and determines if surface is concave, convex, S-shaped.
