ABSTRACT:
An animal feed distribution device that includes a feed conveyor system which fills animal feeding station feed supply bins from central storage. The bins are connected in parallel to the conveyor system, and they receive feed from the system in sequence. At least the last bin designed to receive feed contains an end-looking, infra-red emitting diode component, and a counterpart photo-transistor sensor component, the components providing input information to an electrical control system circuit as the result of the interruption or non-interruption of an infra-red beam passing between the components. The control system circuit activates or deactivates the conveyor system in response to such interruption or noninterruption, which occurs as a conseqence of the feed level in the bin. Both sensor components are mounted opposite each other so as to extend inwardly for a minimum distance from the interior of the bin walls. The system control circuit includes a first delay circuit that prevents generation of a control signal for a predetermined period of time following an interruption of the beam, a second delay circuit that delays generation of a control signal for a predetermined period of time after commencement of beam transmission, and a third delay circuit which limits the duration of a control signal resulting from the beam transmission.
