ABSTRACT:
The present invention relates to a high speed asynchronous fruit sorter, particularly suitable for pit scanning of cherries in order to segregate cherries containing pits from pitted cherries. In a conventional fruit sorting apparatus including a plurality of driven conveyor belts arranged in a cascading configuration wherein the conveyor belts each have laterally spaced and longitudinally extending fruit receiving channels across the width thereof, an optical detection system operatively associated with the last conveyor belt, and an air ejection system so as to optically scan each article of fruit being conveyed and eject unsatisfactory fruit from the sorter with an air pulse, the improvement of providing novel and enhanced fruit control and scanning capability by incorporating vertically raised fruit receiving channels into the last conveyor belt of the sorter to facilitate both horizontal and vertical optical scanning of each article of fruit and further providing a plurality of spaced guide bars above each of the conveyor belts for entraining articles of fruit onto the fruit receiving channels of the conveyor belts therebeneath.
