  • Publication number: 20210380353
    Abstract: Apparatus and methods for destacking objects are disclosed. An apparatus includes a robotic arm, and an end effector connected to the robotic arm. The end effector including a grasping element for grasping an object and means for clearing a surface of the object before the grasping element grasps the object at the surface. A method for mechanically destacking dishware involves moving an end effector near to a top dish in a stack of dishware, clearing an area on a surface of the top dish by sweeping a scraper bar of a scraper mechanism over the surface of the top dish in a first direction, wherein the scraper bar is mechanically connected to the end effector, and grasping, with a grasping element of the end effector, the top dish at the area on the surface of the top dish that has been cleared by the scraper.

  • Patent number: 10974750
    Abstract: A dish cart includes a top with a slot for receiving a lift arm that may be lifted up through the slot to raise or lower dishes. Lobe openings emanating from the slot receive lobes of a lift paddle secured to the lift arm. The cart may define a gap below the top for permitting insertion of the lift paddle and the lift arm. The cart may be adjusted to receive differently sized dishes by means of rails of different sizes or adjustable vanes. A dish drop station includes the lift arm and lift paddle and a lift mechanism for raising and lower the lift arm. The dish drop station may include a cart present sensor and include a lock for retaining the cart. The controller may be programmed to the lower the lift arm to an unlock position that disengages the cart lock.

  • Patent number: 10843877
    Abstract: A system for grasping and retaining dishware during a cleaning cycle. The system includes a grasping element and a receiving surface substantially adjacent to the grasping element. The grasping element grasps the dishware, and the receiving surface receives and retains the dishware during at least one stage of a cleaning cycle. The receiving surface rotates about an axis to convey the dishware to at least two unique locations. A corresponding method is also described herein.
