COATING DEVICE, IN PARTICULAR PAINTING ROBOT

The invention relates to a coating device (e.g. a painting robot) for coating components (e.g. motor vehicle body components) with a coating agent (e.g. paint), comprising - a protective region (8) which is explosion-proof due to the risk of explosion (e.g. as a result of an explosive atmosphere, e.g. due to gas or dust) and/or is under high voltage during operation, - an unprotected region (9) in which an explosive atmosphere is not present or is only occasionally and very rarely present during normal operation and which is therefore not explosion-proof and/or lies at ground potential during operation, - multiple sensors (10-13) for measuring process variables of the coating device, said sensors (10-13) being arranged in the protective region (8), - a data interface (16) for an external data communication, said data interface (16) being arranged in the unprotected region (9), and - a transmission system (21) for transmitting data between the sensors (10-13) in the protective region (8) and the data interface (16) in the unprotected region (9). According to the invention, a collecting device (14) is additionally provided in the protective region (8), wherein the collecting device (14) is connected to the sensors (10-13) and obtains measurement values of the process variables from the sensors (10-13), and the collecting device is also connected to the transmission system (21) in order to transmit the measurement values of the sensors (10-13) to the data interface (16).
