<p>OPTICAL DETECTING SYSTEM FOR ARTICLE COUNTING MACHINE An optical detecting system for a machine for counting individual articles and delivering a preselected quantity of articles into receptacles. The system optically illuminates individual article receiving locations on an endless conveyor made up of elongated article receiving flights and produces optically-detectable indications of the presence or absence of an article at one or more article receiving locations. A reflector displays the opticallydetectable indications to an optical detector, such as a camera, which generates an electronic signal representative of the optically-detectable indication. Associated circuitry generates a second electronic signal indicative of the presence or absence of an article in one or more receiving locations. The second electronic signal may be used to derive a count of articles delivered into the receptacles, and to actuate ejection of receptacles which are under-filled.</p> |
