  • Patent number: 7284653
    Abstract: Apparatus and methods using conveyor belts with activated diverting rollers to maintain the leading edge of a conveyed article while changing the direction of conveyance. A first conveyor belt advancing in a first direction abuts a second conveyor belt advancing in a second direction transverse to the first direction. Both conveyor belts have diverting rollers that rotate on axes oblique to the direction of conveyance. The diverting rollers of each are activated by rolling on an underlying bearing surface to rotate in the vicinity of the junction of the two conveyor belts. The diverting rollers in the first conveyor belt direct the article toward the second conveyor belt. The rollers in the second conveyor belt direct the article toward a side of the second conveyor belt. An article lying on both belts simultaneously rotates by the combined action of the two sets of diverting rollers acting on opposite ends of the article.

  • Patent number: 7147097
    Abstract: A bidirectional sorter using an automated guide to selectively divert articles off a transverse roller-top conveyor belt. A sorting station forms a segment of a conveying line conveying articles in a conveying direction. The sorting station includes a transverse roller-top belt having rollers protruding above an outer surface of the belt. The rollers are arranged to rotate about axes in the conveyor direction to provide a low-friction rolling surface to articles being pushed sidewise on the belt. A guide suspended above the belt is positionable over the belt at positions to intercept conveyed articles and guide them atop the rollers off one side of the belt or the other. The guide is also movable to a bypass position that allows conveyed articles to pass freely through the sorting station.
