  • Publication number: 20200197975
    Abstract: A dispensing apparatus having various features is described. The dispensing apparatus can receive a cartridge having a movable plunger configured to direct the fluid through a dispensing valve. The plunger can be movable under a force applied by air pressure. The cartridge can be inserted in the dispensing apparatus using a clamping and sealing mechanism and can be released using a cartridge ejector. The dispensing apparatus can include a ball valve having a ball defining an internal passageway that selectively aligns with a second internal passageway outside of the ball, a brush mounted via an elongating mechanism, and/or a gear train transmitting power from the elongating mechanism.

  • Patent number: 10675653
    Abstract: A dispensing apparatus is disclosed for dispensing fluid, such as liquid adhesive, from a fluid cartridge having a plunger movable between opposite ends within the cartridge. The dispensing apparatus is releasably coupled to a robot in order to control discharging of the fluid at a particular location. Movement of the plunger is carried out by a cartridge actuator assembly that includes a linear actuator, such as a servomotor, that moves a piston rod into engagement with the plunger such that the plunger can be movable under a force applied by the piston rod. A dispense section of the dispensing apparatus includes a valve assembly with a snuff-back mechanism that prevents excess dripping from an outlet of the dispenser. An end effector assembly may be coupled to the dispense section for dispensing the fluid to an application site in a precise and controlled manner.

  • Patent number: 9387504
    Abstract: A cartridge dispenser generally includes an actuator, cartridge carrier, a removable cartridge, a dispenser head, and a cartridge piston. A sensor is configured to sense data and provide feedback data for controlling the actuator. The dispenser head is a multi-piece assembly allowing removal of an outlet flow tube for maintenance purposes. The tube may be a resilient tube and pinch valves are provided for fluid flow control from the dispenser.

  • Patent number: 7690539
    Abstract: A viscous material dispense system including a dispense valve having an outlet, a mix tube secured at an upper end thereof to the outlet of the dispense valve, a mixer shroud positioned telescopically over the mix tube and including a conical lower end, and an air shroud fitted telescopically over the lower end of the mixer shroud and defining a conical surface positioned in confronting relation to the conical tip portion of the mixer shroud. The air shroud and the lower end of the mixer shroud coact to define a plurality of circumferentially spaced axially extending flutes extending downwardly between the outer surface of the mixer shroud and the inner surface of the air shroud and a plurality of circumferentially spaced radially extending flutes defined between the conical tip portion of the mixer shroud and the conical surface of the air shroud.
