Abstract
Abstract An inspection device is disclosed for inspecting glass containers for leaners and chokes as they are moved continuously past a single work station. The invention utilizes a video camera and processing circuits for determining the size of the opening of the finish of each container as well as the extent of its lean relative to predetermined acceptable limits. Containers having excessive lean or choke are rejected.

Claim 1
Independent Claim
157 words
Apparatus for inspecting a bottle moving continuously on a conveyor past a work station, comprising: a light source for illuminating the interior of said bottle at said work station; trigger means for detecting the position of said bottle at a predetermined point relative to said work station; a video camera for viewing light from said light source at the opening of said bottle and for producing video signals representing an instantaneous image of said opening when said bottle is at the predetermined point, at which point said video camera is aligned substantially along a vertical center line of said bottle; processing means responsive to said video signal and said trigger means for determining the area of the opening of said bottle; and means for comparing said area with a predetermined minimum acceptable area of the bottle opening, and for causing rejection of the bottle if the area of said opening is less than said minimum acceptable area.
Claim 2
Dependent Claim
