  • Patent number: 10106323
    Abstract: A system for positioning a lifting cart in an automated storage facility is described. In one example, the system includes a motorized lifting cart configured to move about a railway of a storage area. An encoder on the cart reads a property of rotation of a rotating element on the cart, and a controller may receive the property of rotation from the encoder and convert it to a rotation count of the rotating element. The rotating element may be an encoder shaft, drive shaft, and like elements. Some systems include a signal emitter or photo sensor to position the lifting cart and to facilitate providing instructions to the cart.

  • Patent number: 8813943
    Abstract: A positive displacement sorter includes a plurality of interconnected parallel slats defining an endless web that travels in a longitudinal direction. The web has upper and lower runs and transition sections between the upper and lower runs. An upper surface of the upper run of the web defining an article-conveying surface. A plurality of pusher shoes travels along at least one of the slats in order to laterally divert articles on the conveying surface. Each of the shoes has a diverting member extending below the conveying surface. A plurality of diverting rails below the conveying surface is capable of engaging the diverting member to cause the associated shoe to travel laterally to divert an article.
