A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

Mushroom harvester

A device for harvesting mushrooms from a mushroom bed involves a robotic arm configured to interchangeably deploy one of a plurality of different suction grippers, each of the suction grippers having a suction cup having a size and shape profile appropriate for gripping a cap of a mushroom, the cap having a size and shape profile within a predetermined range. A vacuum source in fluid communication with the suction gripper supplies negative air pressure to the suction gripper for retaining a cap of the mushroom to be harvested in the suction cup. A control circuit in electronic communication with the suction gripper and the vacuum source is configured to automatically adjust the negative air pressure in the suction gripper in response to harvesting requirements during a mushroom harvesting process. A few standard mushroom shapes have been identified, which permits suction cup designs that maximize contact between the suction cups and the mushroom caps, which permits minimizing the strength of the vacuum needed to harvest the mushrooms.
