The invention relates to a system for coating articles (4) which in known manner comprises a coating booth (1), a conveyor system (5), which guides the articles (4) to be coated through the coating booth (2), and at least one application unit (8, 9), which is carried and guided by a handling device (6, 7). A central supply unit (14) comprises a tank (14b) for storing CO2 in liquid or solid form and conveying means, which are able to remove CO2 from the tank (14b) and supply it at a suitable pressure to a collecting line (13). Said collecting line (13) is connected to at least one cleaning apparatus (10, 11), which in turn comprises at least one nozzle of suitable design for delivering CO2 for cleaning purposes. Under program control a relative movement between the nozzle and the application unit (8, 9) is induced, such that all surfaces of the application unit (8, 9) to be cleaned can be reached by CO2. In this manner a complete automation of the cleaning of the outer surfaces of the application unit (8, 9) and optionally adjacent regions of the handling device (6, 7) is possible. |
