EGG COUNTER FOR COUNTING EGGS TRANSFERRED BY EGG COLLECTION CONVEYER

摘要

An egg counter for counting eggs transferred by an egg collection conveyor has an infrared light receiving element row, a first infrared light emitting element row placed at one side section of the infrared light receiving element row, a second infrared ray emmitting element row placed at the other side section of the infrared light receiving element row, and a control means for processing reflection infrared light received by the infrared light receiving element row. The infrared light emitting element rows and the infrared light receiving element row are placed such that infrared light emitted from each of the first and second infrared light emitting element rows is reflected at the surface of an egg passing directly below the infrared light receiving element row and then the reflected infrared light is received by the infrared light receiving element row. The control means measures the intensity of the reflected infrared light to detect a peak value of the light intensity and then counts eggs based on two peak values of the light intensity relative to the first and second infrared light emitting element rows.
