  • Helical conveyor apparatus with integrated pass-through
    Patent number: 8561782
    Abstract: A material handling system has a helical conveyor apparatus operable in a first mode in which the orientation of a product can be changed and a second mode in which the orientation of the product is unchanged, i.e., passed through. The helical conveyor apparatus has a pair of conveying surfaces, with at least one of the conveying surfaces pivotal relative to the other conveying surface. The conveying surfaces can thus be arranged to twist the product as it is being conveyed or pass the product unaltered.
    Type: Grant

  • Conveyor apparatus
    Patent number: 7845486
    Abstract: A conveyor apparatus for diverting product from a single lane to one of a plurality of lanes includes a wall having an upstream portion positioned proximate the single lane and a downstream portion positioned proximate the plurality of lanes. The upstream portion is stationary relative to the single lane and the downstream portion is configured to be movable relative to the plurality of lanes. A length of the wall is configured to vary in response to movement of the downstream portion.
