Abstract
An optical inspecting apparatus for detecting the absence of an object from a cavity of a slat filling machine. The inspector detects the empty cavity, determines the container which will be short filled and tracks the container and causes the ejection of the container from the production line. Discrete photodiodes lined along the cavity path are actuated in sequence and phototransistors detect whether light passes through the slat. The control computer using data in its memory analyzes the result of scanning through the diodes to determine the short filled bottle and causes its ejection as it passes an ejection station.
