ABSTRACT:
Fruit or other objects placed on the conveyor and spun by the conveyor are properly oriented on the conveyor by the method and apparatus of the invention by ejecting one or more adjacent touching objects or ejecting objects which form stacked triplets. An optical sensor determines when there is or is not a gap between objects and relates that gap detection to the position of the objects on the conveyor. Detection of a continuous signal through a controller circuit causes a downstream solenoid to be energized according to predetermined timing. The solenoid in turn, when energized, rotates a finger which is coupled to, carried with the conveyor system and situated underneath the pocket between adjacent spools. The finger rotates upwardly and ejects the objects sitting in the pocket, thereby removing the misplaced or touching objects on the conveyor belt.
