ABSTRACT:
A selective discharge mechanism for gently, yet positively, ejecting fruit or other damageable articles from a conveyor comprised of a spaced pair of thin supporting belts. The discharge mechanism includes a pair of rotary spiders which are positioned closely adjacent to and just inside of the upper runs of the supporting belts with each spider including three relatively flexible and radially extending arms equiangularly spaced 120.degree. apart and projecting from a central hub mounted for controlled rotary movement. A rubber abutment member is provided at the distal end of each of the arms for resilient contact with the undersurface of a fruit on the conveyor. The discharge mechanism is selectively triggered by signals which signify the approach of a fruit, and such signals may cause one of the spiders to be rotated through 120.degree. to permit one of its projecting abutment members to flexibly engage the lower undersurface of the fruit and deflect the fruit laterally from the conveyor in the desired discharge direction.
