ABSTRACT:
An object sorting apparatus has a singulation section, a sorting section, and a transfer section for transitioning objects, such as fruit, to be sorted to a conveyor which drops the objects into appropriate collection bins. Objects for sorting are transported on an endless conveyor or wheels through the singulation and sorting section. A first independently adjustable speed belt in the singulation section rotates in a direction opposite that of the flow of items from the singulation section to the sorter section, to assist in singulation. A second adjustable speed belt rotates in the same direction as the wheels and operates to provide a view of each of four sides of the object to an imaging device. The imaging device supplies signals representing a desired sorting parameter to a processor which evaluate the measured parameters and generates signals so that the objects are ultimately deposited in appropriate sorting bins. An object holder receives an object as it is about to be dropped onto a second conveyor for transport to the collection bins. The object holder, which is pivotally attached to the wheels, acts to extend the lateral distance of the object beyond the return location of the endless conveyor. This reduces the vertical distance the object must fall before it is captured by a transport cup on the second conveyor, thus reducing damage to the objects, such as bruising of fruit. A rotatable transfer roll is positioned between the conveyors to restrict vertical travel and impart lateral motion to the objects as they leave the object holder. The transfer is preferably padded to further reduce the risk of bruising the fruit.
