ABSTRACT:
Method and apparatus for detecting and intercepting an irregular product in a product flow are disclosed. The product flow is conveyed along a path from a first, product feed station past other product handling stations. Product flow is singulated and aligned at a guide station. The product then is delivered along a product flow axis and in a single file manner to an inspection station where the product, which may be processed, pitted fruit, is graded for firmness and where extraneous matter, such as fruit pits or portions of pits, is detected. Detection involves probing or otherwise impaling each individual product in the flow with a plurality of spaced, pin-like projections. An irregular product resists such probing and produces a pressure differential between the projections and the conveyor belt by which the irregular product is detected. After inspection, detected irregular products are discharged from the product flow. The resulting delivered product flow is of uniform grade and quality, and does not contain extraneous matter, such as fruit pits or portions of pits.
