  • Patent number: 10739064
    Abstract: An apparatus includes a high side heat exchanger, a load, a compressor, a belt, a first bin, a second bin, and a controller. The high side heat exchanger removes heat from a refrigerant. The load uses the refrigerant to cool an enclosed space. The compressor compresses the refrigerant. The first and second bins are coupled to the belt and positioned within the enclosed space. The controller receives a first message, determines that the first bin should be selected, and cycles the belt to move the first bin to a retrieval location within the enclosed space. The controller also receives a second message, determines that the second bin should be selected, and cycles the belt to move the second bin to the retrieval location.

    Abstract: The present disclosure provides workpiece feed systems, methods and assemblies comprising one or more tapered feed rolls positioned at an angle to incoming workpieces. The tapered feed rolls may pull individual workpieces toward a guide while gradually accelerating the workpieces and altering their direction of travel. The angle and speed of rotation of the tapered feed rolls may be automatically adjusted to control workpiece speed/acceleration, providing improved gap control and minimizing collisions between successive workpieces. Tapered feed rolls may therefore reduce or eliminate the need for a conventional bridge to decelerate the workpieces after the directional change, reducing the operational space required by a workpiece feed system.

    Abstract: A sorting switch for diverting articles from one or more infeed conveyors to two or more outfeed conveyors. A cannulae pre-alignment conveyor receives articles from one or more infeed conveyors and selectively diverts individual articles into two or more lateral regions for delivery to an alignment conveyor downstream. The alignment conveyor more precisely aligns the articles within each of the regions for delivery to outfeed conveyors at the downstream end of the alignment conveyor. The alignment and pre-alignment conveyors are realized as belt conveyors with rollers arranged to rotate universally or on axes in specific orientations. In some versions, a belt's rollers roll on bearing surfaces whenever the belt is advancing. In other versions, rollers are selective actuated by moving bearing surfaces. In yet other versions, rollers are not contacted by bearing surfaces at all.

    Abstract: A conveyor system including a pair of roller-top belts arranged side by side, each individually controllable to cause articles conveyed atop both to rotate into preferred orientations. The roller-top belts include rollers that rotate about axes oblique to the direction of belt travel. The rollers on each belt direct conveyed articles toward the other belt as the belts advance in the direction of belt travel and the rollers contact an underlying bearing surface in rolling contact. The rotation of the rollers exerts a force on articles conveyed atop the rollers. The force has a component directed toward the other belt and another component directed downstream. A sensor array senses the footprint of an article at an upstream location and sends signals to a controller that determines the size and orientation of the article to selectively stop one or the other roller-top belt if necessary to rotate the article to change its orientation.
