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.

The disclosure relates to an operating method for a coating system, in particular for a painting system, for coating components (2), in particular motor vehicle body components (2), having the following steps: conveying, by means of a conveying device (3), the components (2) to be coated in a conveying direction through a coating booth (1), coating the components (2) in the coating booth (1) with a coating product by means of an application device (17-19) which applies a spray jet of the coating product, a portion of the applied coating product being deposited on the components (2) to be coated while another portion of the applied coating product floats into the interior of the coating booth (1) as an excess coating product mist (21), and reducing the excess coating product mist (21) from the interior of the booth by means in addition to or other than the downwardly directed air flow generated by a filter ceiling. In addition, the disclosure includes a correspondingly designed coating system.

A method for recycling powdered paint waste is provided in which, the powdered paint waste is being treated with the aid of a reactant in such a way that its adhesion to surfaces and especially to metal surfaces is reduced or eliminated. The treatment of the powdered paint waste allows the powdered paint waste to be additionally processed under the influence of heat and to use it as a starting material in various recycling processes or in other processes.

A particulate spray booth having a sealed particulate spray device booth wall opening is disclosed. The powder coating material spray system may include a booth comprising a ceiling, a floor, and side walls defining an interior of the booth, wherein the booth defines an opening from the interior of the booth to an exterior of the booth. The system may further include a powder spray device received through the opening, the powder spray device comprising a body and a nozzle through which powder coating material is sprayed into the interior of the booth, wherein the nozzle and at least part of the body are disposed in the interior of the booth. The system may further include a flexible boot element having a proximal end and a distal end opposite the proximal end, the proximal end attached to a periphery of the opening to form a first seal and the distal end attached to the at least part of the body of the powder spray device disposed in the interior of the booth to form a second seal.

A coating cabin for coating vehicle wheel rims has a coating chamber and a conveying device for transporting the workpieces for coating through the coating chamber. An applicator system is furthermore provided for spraying coating material as required in the coating chamber, wherein the applicator system has a first pistol system for spraying coating material as required onto a first region of the workpieces for coating, a second pistol system for spraying coating material as required onto a second region of the workpieces for coating, and a third pistol system for spraying coating material as required onto a third region of the workpieces for coating.

A robotic system is provided for repeatedly and reproducibly applying a sealant to a seam in an assembled HVAC duct component. The applied sealant has a predetermined location on the assembled HVAC duct component to seal the seam. An assembled HVAC duct component is thus provided having a robot applied sealant on at least one seam in the assembled HVAC duct component, wherein the applied sealant has at least one of a predetermined location, thickness or coverage. The robotically applied sealant can be applied to a blank for forming the assembled HVAC duct component, wherein the sealant is located at locations forming a seam in the assembled HVAC duct component.

A recirculating powder applicator includes an applicator body having an inlet on an upstream surface and an outlet on a downstream surface, wherein the inlet and outlet define a passage that extends transversely through the thickness of the applicator body, a powder conduit, an air inlet, an exhaust aperture located on one of the upstream or downstream surfaces, and a circulation chamber located on the interior of the applicator body. The powder conduit and air inlet are in fluid communication with the passage and the passage is in fluid communication with the circulation chamber. A method of applying powder to a substrate during a continuous process includes using a recirculating powder applicator.
