SU1630729A1 - Device for grading eggs - Google Patents

Abstract

The invention relates to agricultural machinery, in particular to devices for sorting into weight categories of eggs of agricultural birds. The aim of the invention is to increase productivity. The device contains a drive 1, roller conveyors 2, 6, a tele sensor, a volume calculation unit 4, a fixed memory (ROM) 5, an opaque screen 7, a synchronization device 8, light sources 9, 10, a translucent mirror 11. a reflecting mirror 12, pulse distributor 13, light-tight casing 14. The device operates as follows. When the egg, located on the conveyor 2, falls into the field of view of the telesensor 3, the television sensor scans the image of the egg, with the scanning line perpendicular to the major axis of the egg. The volume calculation unit 4 determines in each row of the image the diameter of the egg and calculates its volume. Depending on the value obtained from the output of the ROM 5, a command is given to the actuator to assign the bird to a certain category. 6 Il. Ј (L
