Method for inspecting the quality of folding boxes during their production

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.
