Equipment for automatically monitoring the verticality of bottles

摘要

An apparatus for detecting nonverticality of small-mouthed bottles comprises means for training a light beam across a conveyor path and, in the region of this light beam further means for directing a light beam downwardly on to the path and into the mouth of the bottle. A detector responds to reflective light from the lip or rim of the mouth so that the offset of the center of the mouth and the base of the bottle can be detected.
