A powder coating plant for coating a workpiece with coating powder includes a booth, which receives the workpiece delivered via a floor conveyor. In addition, the powder coating plant has an upper spray applicator arrangement for spraying coating powder downward, and a lower spray applicator arrangement for spraying coating powder upward. The upper and the lower spray applicator arrangement are thereby oriented toward the same workpiece. In addition, a manipulator is provided, to which the upper and the lower spray applicator arrangement is fastened. The manipulator is formed such that the spray applicator arrangements can be moved at least in the transport direction of the workpiece by the manipulator.

According to the present disclosure, methods and techniques for generating preferred concrete block products are provided. The methods and techniques involve providing addition of color to selected section within the blocks (1), as described herein, to generate enhancement effects. Typical applications involve spray applications for color pigment to visually distinct sections of the block (1) on one or more decorative surfaces.

A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame having a workpiece receptacle, a coating agent source, a compressed air source, and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection, and on the pressure side being connected to the spray units. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The valve on the inlet side is connected to the compressed air source by a fluid-conducting rotary feedthrough and on the exhaust air side is connected to the compressed air controlled valves of the spray units.

A repair machine is provided. The repair machine is structured to apply a repair fluid to a plurality of can ends. The repair machine includes a can end down stacker assembly, a can end conveyor assembly, and a spray assembly. The can end down stacker assembly is structured to move individual can ends from a stack to a conveyor assembly. The can end conveyor assembly is structured to transport the can ends over a path, the can end conveyor assembly including a number of reference locations. The can end conveyor assembly is disposed adjacent to the can end down stacker assembly and receives can ends therefrom. The spray assembly is disposed adjacent to the can end conveyor assembly downstream of the can end down stacker assembly. The spray assembly includes a locator assembly, a spray gun assembly, a motion assembly, and a control assembly.

A multi-angle wash system for cleaning carcass, wherein the wash system comprises a multi-angle fluid distribution unit; a rotating unit; a spray unit fluidly and operably coupled to the multi-angle fluid distribution unit; and a guiding unit operably coupled to the spray unit or the multi-angle fluid distribution unit. The multi-angle fluid distribution unit comprises a connecting element that is configured to operably couple with the spray unit such that the spray unit oscillates in correspondence to the rotation of the rotating unit. The spray unit comprises a guiding element and nozzle sprays. The guiding unit comprises a co-guiding element that has a reciprocate structure to the guiding element of the spray unit such that the guiding unit facilitates the oscillation of the spray unit in correspondence to the rotation of the rotating unit.

A rotary tank assembly is provided for a liner. The liner is structured to apply a compound to a plurality of container closures. The rotary tank assembly includes a compound tank, a fill tube structured to fill the tank with a volume of the compound to a desired level, a sensor assembly adapted to measure the level of the compound within the compound tank, and a rotary union assembly structured to pivotably couple the fill tube and the sensor assembly to the compound tank. The sensor assembly only requires one single probe.

Apparatus for painting mainly flat products including a spray booth, in its turn including a plenum, a conveying belt for conveying products at least a device for applying paint, and at least one suction plant, wherein the plenum of the spray booth has a symmetric M-shape including, from the respective peripheries to the centre of the plenum: two first descending surface portions tilted towards the periphery; two second lateral surface portions parallel to the belt; two third descending surface portions, with a tilt towards the centre, opposite the tilt of the first portions; a fourth central surface portion parallel to said belt, the fourth central surface portion being closer to the conveying belt than the lateral parallel sections.

Systems for applying a masking material to a substrate, the system comprising: a source feed for delivering a quantity of masking material to a substrate, a waste deposit for receiving masking material when removed from the substrate, a spray nozzle moveable relative to the substrate and a controller for controlling movement of the nozzle relative to the substrate and the speed of delivery of the masking material from the source feed, wherein the speed of movement of the spray nozzle relative to the substrate is substantially equal to the speed of delivery of the masking material from the source feed.

A modular apparatus for coating glass articles with a chemical compound includes a coating hood section (10a) including a series of interconnected walls (12) defining an interior chamber (18, 20a, 20b) having an inlet (32) and an outlet (44), a blower (24) positioned at least partially in the interior chamber (18, 20a, 20b) to carry air from the inlet (32) towards the outlet (44); and a connector (50) for connecting the coating hood section (10a) to an identical coating hood section (10b). The connector (50) for connecting being defined on at least one of the interconnected walls (12) of the coating hood section (10a).

An electrostatic powdering robot for a powder booth, the robot including a projector for performing electrostatic powder coating. In order to reduce the time required for powder removal from the booth and facilitate automation of powder removal, the robot further includes a robotic arm, which is articulated and which carries the projector for positioning the projector, as well as a blower, for blowing a powder removal fluid, preferably air, the robotic arm carrying the blower to position the blower inside the booth, so that the blower blows the powder removal fluid onto a surface to be de-powdered inside the electrostatic powdering booth and thereby removes the residual powder coating the surface to be de-powdered.
