  • Patent number: 10167098
    Abstract: A “weigh/fill” type box filler for cherries, cherries and similar small produce that incrementally moves and fills an array of individual packaging bags within conventional packing boxes. The box filler includes a box conveyer, a producer conveyer, a metering gate, a weigh/fill scale assembly and three independent box lifters. The box conveyer moves the packing boxes incrementally over the weigh/fill scale assembly to position each row of bags within successive packing boxes beneath the metering gate. As one packing box is incrementally moved across the weigh/fill scale assembly and each row of bags is weigh/filled, the box lifters sequentially raise the adjacent preceding and following packing boxes out of contact with the weigh/fill scale assembly. The metering gate uses independently actuated gate paddles to selectively control the flow of produce into the individual bags first at a high volume “gross” fill rate and finishing with a lower volume or “fine” fill rate.

  • Patent number: 7437791
    Abstract: An apparatus for removing Japanese beetles and other insects from blueberries and other small produce without damaging or discarding any produce. The apparatus includes a produce conveyer formed by a plurality of elastic bands trained around four traverse rollers. A plurality of brushes are suspended above the top conveyer run and a plurality of rakes are supported between the top conveyer run. The brushes have soft, flexible bristles, which extend downward to contact the blueberries as it moves past the brushes carried atop the conveyer. The rakes have a plurality of spaced fingers that extend upward at an angle between adjacent conveyer bands. As the blueberries pass under the brushes, the bristles lightly contact the berries to gently turn the berries so that the beetles hang from the underside of the berries where they are knocked off the berries by the rake fingers.

  • Patent number: 6907981
    Abstract: A conveyer assembly used as part of an automated packaging system is disclosed. The conveyer assembly allows the container filling process and produce leveling process to be combined as a single process station in an automated packaging system. The conveyer assembly includes a pair of elastic belts trained about two pulleys, four vibration isolation rollers, and a vibrator mechanism. The vibration isolation rollers are mounted to the frame structure and positioned at incrementally higher positions, which creates a slight incline to the conveyer belts over the first half of the conveyer run. The highest isolation roller, which is located at the center of the conveyer assembly, isolates the first half of the conveyer run from the vibrations generated by the vibrator mechanism. Consequently, the first half of the conveyer run where the produce is deposited into the containers is stable and free from vibration, which reduces the loss of produce due to spillage.

  • Patent number: 5810175
    Abstract: An apparatus for sorting round produce by diameter size using a conventional transport conveyer assembly and including a sorting size adjustment mechanism to automatically adjust the produce sorting size and an anti-pinch mechanism to prevent damaging the produce during the sorting process is disclosed. The conveyer assembly has a horizontal top run and a V-shaped bottom return run formed by a plurality of elastic conveyer bands trained about three elongated roller shafts. The conveyer bands are spaced across the width of the roller shafts at a fixed horizontal distance. As the produce is transported across the top conveyer run, the produce, whose diameter is smaller than the spacing between the adjacent conveyer bands, falls between adjacent conveyer bands for collection and the remaining produce travels to the end of the top conveyer run for separate collection.
