Abstract

An apparatus and a method for measuring the shape of an article flowing on a conveyor, the measuring apparatus being characterized by comprising, a conveyor for mounting and moving an article to be measured, means disposed at a measuring part of the conveyor, for measuring the apparent length of the object as it passes, means disposed above the conveyor, for picking up the image of the object, and means for operating the width, depth and height dimensions of the object using length measurement data from the length measuring means and image data picked up by the image pickup means. The length measuring means comprises a photoelectric sensor projecting light in the direction orthogonal to the advancing direction of the conveyor, and calculates the apparent length of the object based on the light interception time due to passage of the object and the conveyor speed.
