Abstract

PURPOSE: To sort fruit by sizes by using the mean value of addition between two obtained values by optically detecting the diameter of the uniformly-carried fruit in the lateral and longitudinal directions perpendicular to the conveyance direction.
CONSTITUTION: Objective fruit A, supported on bucket 1 in conveyance in the arrow direction, passes between projector 5 and photo detector 6 over it and its mobility is measured to obtain an external diameter in the moving direction. In the same way, the external diameter perpendicular to the moving direction is measured by projectors 7 and 8 and photo detectors 9 and 10 over them. Measurement of the external diameters in lateral and longitudinal directions is done by several projectors and photo detectors via bucket notch parts 4a and 4b. Then, the external diameters in the both directions averaged by the arithmetic part to sort the objective fruit.
