Folding box quality testing method for use in transport region, involves testing right folding of laid folding box by detection of surface unevenness of side surface of folding box stack in subsequent to alignment and stacking of laid box

摘要

The method involves testing a right sequence of folding boxes by controlling existence of an adhesive strip of a laid folding box in a given target region in subsequent to adherence of the former folding boxes. The former folding boxes are arranged on top of each other. A right folding of the laid folding box is tested by detection of surface unevenness of a side surface of a folding box stack in subsequent to alignment and stacking of the laid folding box. A light strip is formed on the side surface for detecting surface unevenness of the side surface by a light source. Independent claims are also included for the following: (1) a device for testing quality of a folding box (2) a computer program for testing quality of a folding box during manufacturing of the folding box.
