Abstract: A method and apparatus for inspecting the bottom of a transparent container for defective conditions, such as internal stuck glass, internal loose glass or foreign material. The container is provided in an inspection zone and a linearly extending line of light from a light source is focused to pass through the container bottom with the line of light extending the length of the inspection zone and hence the length of the container bottom. The linearly extending line of light enters the container through the exterior surface of the container bottom. The intensity of the light reflected from defects in or within the container and through the container side wall at a predetermined angle is detected. The detected intensity of the reflected light is compared with a predetermined threshold value that provides a measure of the acceptability of the container.

Abstract: A system for automatically detecting sidewall and dimensional defects in a transparent container includes a laser scanning system positioned astride a conveyor in a production line. In an upstream inspection zone a laser beam vertically scans a portion of the side wall of the container. Photosensors positioned in a detection chamber detect the specific effect which any defect has upon the laser beam by determining the location of light passing through the container and comparing its intensity against pre-set thresholds. A flaw signal is generated when a threshold is exceeded. The number of flaw signals is counted and when the count equals a pre-set value a reject signal is generated to eject the defective container from the conveyor. If a container is not rejected, it passes through a rotator assembly which rotates the container precisely 90.degree..
