ABSTRACT:
A counting system for a poultry processing plant that uses conveyors is disclosed. Two types of conveyors are addressed, one where poultry hang from the conveyor and one where the carcasses are supported above the conveyor. The sensors are located at different levels to sense elements of the carriers as well as poultry. Logic within the system compares the readings of the sensors to determine whether a chicken is present and whether to increment the total. Additionally, the sensors are recessed in steel tubing on mounting plates which support their own cover plates. The sensors can thereby be adjusted for alignment while the cover plates move with the sensors. The cover plates are easily removed for cleaning and put back into position without blocking the sensors. Air is blown through the steel tubing to keep a positive air pressure in the tubing to prevent dirt from entering the openings.
