A robot end effector (100) for dispensing an extrudable substance (102) comprises a chassis (110), a static mixer (101), and cartridge bays (122), extending from the chassis (110). Each of the cartridge bays (122) is shaped to receive a corresponding one of the two-part cartridges (104). Fluidic communication between the selected one of the two-part cartridges (104) and the static mixer (101) is established when the cartridge bays (122) are rotated about an axis (190) to a predetermined orientation with respect to the chassis (110). The robot end effector (100) also comprises a dispensing valve (130), attached to the chassis (110), and a head assembly (150), comprising an inlet manifold (152). The inlet manifold (152) is configured to selectively supply compressed air from a pressure source (199) to contents of a corresponding one of the two-part cartridges (104).

An outlet for a static mixer includes a cannula, a housing accommodating part of the cannula within a passage extending through the housing in an axial direction. The cannula is attached to the housing via a joining member permanently fixed to an outer surface of the cannula, with the joining member being arranged within a recess of the housing, and with the joining member being formed from a material different to the material of the cannula and from the material of the housing.

In one example, a dispensing system has a housing that supports a first and second pumps. The housing defines a receptacle and first and second passages. The receptacle defines at least one hole that extends into the housing that can receive a plug of a fluid dispenser. The first passage extends from the at least one hole to a first pump outlet, such that the first passage can communicate a first fluid material from the first pump outlet to the fluid dispenser. The second passage extends from the at least one hole to a second pump outlet, such that the second passage can communicate a second fluid material from the second pump outlet to the fluid dispenser. The system has an engagement feature that can engage a corresponding feature of the plug of the fluid dispenser so as to releasably secure the fluid dispenser to the housing.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A re-mixing dispenser for containing and dispensing a liquid. The dispenser may have one or more tubes, each containing a different liquid. At least one of the liquids may be re-mixed in situ, using a special two-piece plunger and plunger rod. A mixing piece of the two-piece plunger is moveable independently of a top piece and has blades that allow it to move through the liquid. A plunger rod is removably attached to the mixing piece and is operable to move the mixing piece up and down within the tube during mixing. The two plunger pieces are joined and moved as a single plunger during dispensing.

A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio, and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuators control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.Note

A mixing device for preparing a ready-to-use compound comprising at least one component, which is to be mixed before use, in a cartridge with a tubular mixing rod and a working method with this mixing device and cartridge. The insertion of the cartridge in the mixing device is simplified so that the device can be operated completely automatically, and dispensing of a cartridge to be mixed or a ready-mixed cartridge is preferably be made possible with automated handling means (robots). Because the cartridge holder has a clamping means with which the cartridge can be clamped on the bottle neck-like section, the clamping of the cartridge in the mixer is simplified and can be triggered by force, for example pneumatically.

An adapter couples to a container and includes an adapter body and a mixing element. The adapter body includes a neck section and a cap section. The neck section has a first interior surface that defines a first channel extending therethrough. The cap section is coupled to the neck section. The cap section has a second interior surface that defines a second channel extending therethrough that is in fluid communication with the first channel. The mixing element is coupled to the first interior surface and extends into the first channel.

A device for applying a mixed component, includes first and second receptacles, a static mixing nozzle, an applicator and an operating member. The first and second receptacles are to receive first and second components, respectively. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle. The operating member is configured to control the pressurized fluid.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.
