  • Patent number: 11951611
    Abstract: 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 H 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.

  • Patent number: 11891741
    Abstract: Systems, methods, and software program products for dispensing chemical solutions. A controller receives a signal from a pressure sensor indicative of a pressure of a diluent. The controller determines an expected flow rate of the diluent through an eductor based at least in part on the pressure of the diluent. The controller may further determine an expected concentration of a chemical product in the solution dispensed from a discharge port of the eductor. Based on the expected flow rated and concentration of the chemical product, the controller determines a duration of a dispense stage of a dispensing operation required to dispense a predetermined dose of the chemical product. The controller then causes the diluent to flow through the eductor for the determined duration of the dispense stage. A check valve on the output of the eductor prevents dissimilar chemicals from mixing and reduces a response time of the eductor.

  • Patent number: 11709084
    Abstract: A liquid dispenser includes a housing configured to receive a liquid supply cartridge, and a reservoir disposed in the housing that holds a volume of the product. The reservoir includes an access port for receiving the liquid supply cartridge and placing the liquid supply cartridge and the reservoir in communication. A dosing tank is connected to the reservoir and configured to hold a metered volume of the product. A control valve is movable between an opened position and a closed position, wherein when the control valve is in the opened position, product in the dosing tank is permitted to flow from the liquid dispenser and product flow from the reservoir to the dosing tank is prevented, and when the control valve is in the closed position, product in the dosing tank is prevented from flowing from the liquid dispenser and product flow from the reservoir to the dosing tank is permitted.
