ABSTRACT:
Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilience are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. [By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available.]
