  • Publication number: 20090306814
    Abstract: Produce sorting equipment comprising: a conveyor driving a plurality of carriers spaced along the conveyor to support a single produce between adjacent carriers; at least one exit conveyor positioned above the carriers; an air distribution sprocket positioned below at least two adjacent carriers, the sprocket being rotatable about an axis perpendicular to the conveying direction of the conveyor; the sprocket having a plurality of radial arms that terminate below the carriers; each arm including an air conduit; and means to control air flow along each air conduit; whereby as the sprocket rotates each arm passes underneath the carriers and an air blast via the conduit propels the produce supported by adjacent carriers up and off the carriers to fall onto the exit conveyor.

  • Patent number: 7222715
    Abstract: A conveying assembly for fruit handling, comprising a carriage (20) adapted to be attached to a conveying chain arranged to displace the carriage in a conveying direction, a cup (30) adapted to support a single piece of fruit, the cup being secured to the carriage via a parallelogram linkage (41, 42, 22, 35) extending transversely to the conveying direction, the cup being pivotally secured to the linkage to be moveable from a conveying position to a discharge position, the linkage having release means (60) to cause the cup to pivot relative to the linkage transversely of the conveying direction to the discharge position to effect discharge of the fruit, the linkage allowing the cup to be vertically displaceable to effect weighting of the fruit.

  • Patent number: 5878863
    Abstract: A conveying system (10) for foodstuffs comprising a first conveyor (11) and a second conveyor (12) placed side by side with the end of the first conveyor overlapping the start of the second conveyor. The overlapping portions of the conveyors are in close proximity so as to define a transfer zone (25). Each conveyor has a plurality of foodstuff supports each adapted to support a single piece of foodstuff, and a tilting device to tilt the foodstuff support of the first conveyor to cause the foodstuff to roll from the support of the first conveyor to the support of the second conveyor. The first conveyor (11) includes a photographic zone and the second conveyor includes a weighing zone and multiple ejection zones.
