Method For Detecting Defects Of The Horizontal Mold Seal For Glass Containers

Abstract: The invention relates to a method for detecting defects of the horizontal mold seal (JH) on the bottle finish (B) of containers (R), the method comprising the following steps: - arranging the container (R) between a light source and a camera; - rotating the container (R) on itself through one revolution; - acquiring an image by the camera, at each rotational increment of the container, such that the number of images per revolution is greater than 36; - analyzing the images taken for each container in such a way that: * the profile of the edge of the bottle finish is detected in each image; *the profiles of the bottle finish edge are compared with a reference profile of the bottle finish edge, so as to detect differences between these profiles; *and a defect in the horizontal mold seal (JH) is detected for a container when at least one image of the container exhibits a difference.
