  • End of arm tool capable of ejecting totes
    Patent number: 11167423
    Abstract: An end-of-arm tool lifts a stack of totes and ejects a lowermost tote one at a time. The tool includes fixed unloading arms on which an outgoing tote slides in response to a pusher. A pair of staging arms lift the totes above the outgoing tote to free the outgoing tote and enable the outgoing tote to slide on the unloading arms.

  • Gripping tool having adjustable gripping area, and related methods
    Patent number: 10926403
    Abstract: A gripping tool includes at least one linear guide coupled to a mount and extending along a central axis oriented along a first direction. At least one carriage coupled to the linear guide is translatable relative to the mount along the first direction. A first plurality of arms are rotatably coupled to the mount. A second plurality of arms are rotatably coupled to the carriage. The tool includes bodies carrying suction cups. Each body: defines an axis, is rotatably connected to at least one of each of the first and second pluralities of arms, and combines with the respective at least one of the first plurality of arms, the at least one of the second plurality of arms, and the at least one carriage to define a linkage allowing the body to move relative to the mount along the first and a perpendicular radial direction while the central and body axes remain parallel.

  • Material sorting discs with variable interfacial opening
    Patent number: 9283594
    Abstract: A disc screen includes a shaft, a first disc mounted on the shaft, and a second disc mounted on the shaft. An interfacial opening (IFO) extends between the first disc and the second disc. A width of the IFO as measured between the first disc and the second disc varies according to a rotational position of the shaft.
