摘要

#CMT# #/CMT# Apparatus for curing a coating on an article with electromagnetic radiation comprises a radiation source (58) and a conveyor system comprising a lift truck (46) with a motor drive (50) for elevating a platform (54) for receiving the article. The radiation source is arranged so that the lift truck bearing the article can be moved beneath it. #CMT#USE : #/CMT# Curing a coating on an article, especially a UV- or heat-curable lacquer on an automobile body. #CMT#ADVANTAGE : #/CMT# The apparatus gives good results with coatings on articles with complex shapes and uneven surfaces, especially automobile bodies. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing apparatus for curing UV lacquers in longitudinal cross-section. 12 : Automobile body 18 : Preheating zone 22 : Postheating zone 38 : Container 42 : Oxygen-removing device 46 : Lift truck 50 : Motor drive 54 : Platform 58 : Radiation source. #CMT#MECHANICAL ENGINEERING : #/CMT# Preferred Apparatus: The article is an automobile body (12). The radiation source comprises several lamps mounted vertically and horizontally in a container (38) to follow the side and top surfaces of the article. The container has a reflective cladding of aluminum foil and is supplied with an inert gas, especially carbon dioxide or helium. The apparatus includes an oxygen-removing device (42) comprising a catalyst for binding oxygen or a filter for absorbing or adsorbing oxygen. The apparatus includes a preheating zone (18) for removing solvents or for gelling powder materials. The apparatus includes a postheating zone (22) for completing the curing process. Elevation of the platform is controlled as a function of the profile of the article. The radiation is UV light or infrared radiation.
