A coating device comprises at least one application apparatus to discharge a coating agent from at least one coating agent nozzle. The application apparatus is configured to apply an oscillation to at least one of the coating agent and at least one coating agent jet such that at least one of the coating agent and the at least one coating agent jet break up into droplets.

The disclosure relates to a rinsing apparatus for connection to an application-agent main channel of an application-agent changeover unit and preferably for the continuous inflow of a rinsing agent into a flow of rinsing air, having a main line for transporting rinsing air and having a rinsing-agent line for transporting a rinsing agent. The rinsing apparatus is distinguished in particular in that the rinsing-agent line opens out into the main line by way of a mouth opening in order to generate a preferable y continuous flow of a rinsing-air/rinsing-agent mixture for introduction into the application-agent main channel. The disclosure also relates to a corresponding rinsing method.

The apparatus for coating systems comprises: a first feeding unit provided with first loading and unloading means of a first coating powder; a second feeding unit provided with second loading and unloading means of a second coating powder; a pump assembly associated with a spraying system for sending the first powder and the second powder into a coating booth; connecting means of the pump assembly to the first feeding unit and to the second feeding unit, variable between: a first configuration, in which the pump assembly is operatively connected to the first feeding unit for sending the first powder into the booth; and a second configuration, in which the pump assembly is operatively connected to the second feeding unit for sending the second powder into said booth.

The invention relates to a method of operating a metering device (1) for metered dispensing of pumpable media, in particular of color pigment preparations, the metering device (1) comprising a dispensing means (2), which is in fluid connection with a plurality of canisters (3), wherein said metering device (1) comprises a controller (8) by means of which at defined times a defined dispensing volume of the medium is drawn from at least one of said canisters (3) and conveyed to said dispensing means (2) by means of a conveyor (10), wherein, in particular, by means of said controller (8) also an actual fill level is determined and/or calculated depending on a dispensing volume drawn from the respective canister (3). According to the invention, at least one calibration sensor (30), in particular a capacitive sensor, is arranged on said canister (3), preferably on an outer wall of said canister (3), in such a way that it is responsive in the event that the medium in said canister reaches at least a defined known calibration fill level, and transmits a corresponding sensor signal to said controller (8), based on which the controller (8) recognizes the calibration fill level as effective actual fill level and/or takes it over as a new current actual fill level. Further, a metering device and a canister are provided (FIG. 3).

A coating system applicator component, e.g. a valve or bell cup, which may be used to be wetted and/or flown through at least in some sections by a coating agent, is provided. The applicator component includes a cylindrical holding part configured to releasably couple a mount of the coating system, as well as an applicator thread on the holding part. The applicator thread includes first and second applicator flank surfaces each obliquely oriented to a radial direction of the holding part, the first and second applicator flank surfaces being asymmetric about the radial direction of the holding part. The first and second applicator flank surfaces are configured to be parallel to and interface with first and second mount flank surfaces of a thread of the mount, respectively, upon a coaxial, threaded engagement between the holding part and the mount.

The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

The conveying device according to the invention with flushing means comprises a material conveyor (1) for conveying coating material (31). The material conveyor (1), in turn, which has an inlet valve (7), which comprises a valve inlet (7.1) and a valve outlet (7.9). The material conveyor (1) additionally has a conveyor inlet (1.1) for coating material (31), which is connected or can be connected to the valve inlet (7.1). The conveying device furthermore comprises a flushing agent conveyor (3) for conveying flushing agent (30), which is likewise connected to the valve inlet (7.1).

The durability of resin components can be improved by preventing ozone from staying in gaps where there is no air flow. A cylindrical gap is provided around the outer peripheral side of the head portion between the head portion and the resin cover portion covering the outer peripheral side of the head portion. Moreover, the head portion is provided with a pilot air introduction path guiding the pilot air exhausted from the switching valves to the cylindrical gap. In addition, the arm portion is provided with a pilot air exhaust path exhausting the pilot air from the cylindrical gap to the outside.

The present disclosure belongs to the technical field of mechanical spraying, and a color change block with detection feedback as well as spraying equipment are provided. The color change block with detection feedback comprises a cleaning agent valve module, a color change micro valve module, a mixing pipe module and a turbidity detection module which are connected in sequence. A complete collinear common channel is formed among these modules, and the wall surface of the common channel is a complete plane. The turbidity detection module is further connected to the control module and used for monitoring the turbidity of a medium flowing through the common channel in real time so as to determine whether the medium in the common channel meets a cleaning requirement or not and feed a determination result back to the control module, and then the control module switches other media to form a closed-loop control.
