METHOD AND APPARATUS FOR INSPECTING TRANSPARENT CONTAINERS

摘要

Apparatus for inspecting either empty or filled transparent containers for foreign matter in which the containers are moved through spaced apart inspection stations to present different sides thereof to high intensity pulsed light sources which casts the illuminated image beams along paths which intersect at beam directing means operable to align and direct the respective beams into an electronic scanning device, and in which apparatus the containers at the respective inspection stations are not necessarily the same containers so that the inspection at the stations occurs in a predetermined sequence.
