Embodiment Construction

[0040] Referring first to Figures 1 and 2, a portion of a painting installation is indicated generally by the reference numeral 1 therein. The painting installation 1 is used for painting a vehicle body 2 ; various processing stations, not shown, are connected in a known manner before or after the part shown. A vehicle body 2 passes through the painting installation 1 from left to right in FIGS. 1 and 2 . The vehicle body first enters the painting booth 3 in which the vehicle body is coated with paint in a known manner. The exact design of the spray booth 3 and the way in which the paint is applied are not critical in the context of the present invention.

[0041] The vehicle body 2 emerges from the painting booth 3 and first passes into a pre-drying device 4 , the design of which is also not relevant in detail and is known to the skilled person. In the pre-drying device 4, the volatilization / evaporation of the solvent takes place at a temperature between 40 and 150°C. For ...

Abstract

The invention relates to a method and a device for drying an object (2), in particular a painted vehicle body, wherein the object (2) is moved through a drying zone (8) in which the object is Hardened in an inert gas atmosphere. In order to bring in as little ordinary atmosphere as possible from the outside when introducing the objects (2) into the drying zone (8), the objects (2) are guided through a gate zone (7) before the drying zone (8), In the gate area, the normal atmosphere and the inert gas atmosphere existing outside the drying area (8) exist in layers above and below each other due to the difference in density. Objects are transferred from said normal atmosphere into the inert gas atmosphere by a motion having a vertical direction component when passing through the gate area (7).

Description

technical field [0001] The invention relates to a method for drying an object, in particular a painted vehicle body, in which the object is moved through a drying zone in which the object is hardened in an inert gas atmosphere. The invention also relates to a device for drying objects, in particular painted vehicle bodies, having: [0002] a) drying channel, the inner chamber of the drying channel is filled with an inert gas atmosphere; [0003] b) Conveyor system by means of which the objects can be moved through the drying tunnel. Background technique [0004] More recently, lacquers have become increasingly important, which must be hardened in an inert gas atmosphere, for example under ultraviolet light, in order to avoid undesired reactions with components of the common atmosphere, especially with oxygen. These novel lacquers are distinguished by high surface hardness and short polymerization times. The latter advantage is directly reflected in the length of the insta...
