<p>Articles that pass an inspection station seriatim are removed from their subjacent conveyor or not, depending on the results of inspection, by an ejection device which is a pair of vertically superposed horizontal chains that carry between them upright holders on each of which is mounted a rod for vertical swinging movement from an upright inactive position, to a horizontal outwardly projecting active position. Depending on the results of inspection, one of these rods will be pushed down to the lowered or active position to come into registry with the article to be ejected. The endless chains converge toward the conveyor on which the inspected articles rest, so that the rods progressively push the defective articles from their subjacent belt onto a discharge belt, after which the rods are swung back up to their inactive raised position.</p> |
