Definitions
- the invention relates to a device for drying objects, in particular painted vehicle bodies, with
- a drying chamber the interior of which is filled with an inert gas atmosphere
- an inlet lock chamber which communicates at least temporarily with the normal atmosphere present outside the device and at least temporarily with the inert gas atmosphere present in the drying chamber;
- varnishes have become increasingly important, which have to be cured in an inert gas atmosphere, for example under UV light, in order to prevent undesired reactions with constituents of the normal atmosphere, in particular with oxygen.
- inert gas atmosphere for example under UV light
- These novel varnishes are distinguished by a very high surface hardness and due to short polymerization times. The latter advantage translates directly into shorter system lengths in painting systems that are operated continuously, which of course leads to significantly lower investment costs. While in conventional dryers or dryer processes that work with normal air as the atmosphere, the amount of air that is brought into and out of the dryer is of less importance for reasons of cost low consumption.
- the object of the present invention is to design a device of the type mentioned in the introduction so that it can be operated with as little inert gas as possible.
- At least one chamber has at least one boundary wall, which has a shape adapted to the object to be dried and can be moved towards and away from the object located in the chamber.
- the invention is based on the consideration that, in principle, the less inert gas is required, the smaller the volume that is to be filled by the inert gas and the less the inert gas is contaminated during operation.
- the corresponding chambers of the device cannot be made arbitrarily small, since the objects have to be conveyed into or through them.
- the invention is based on the knowledge that a further saving in inert gas can nevertheless be achieved.
- a movable boundary wall can namely be brought closer to the standing object to be dried than a stationary boundary wall, which everywhere must at least maintain the distance from the object which corresponds to its largest dimension in the direction in question.
- the movable boundary wall should have an outlet through which the gas displaced toward or away from the object when the boundary wall moves can flow out.
- the movable boundary wall is designed as a hood, which can be placed over the object by an essentially vertical movement.
- Many objects to be dried in particular vehicle bodies, have a relatively irregular, upward-pointing contour, while they are comparatively flat at the bottom.
- a hood, which is placed over the top of the objects to be dried, can therefore achieve a large volume reduction.
- a particularly small carryover of normal atmosphere into the drying chamber is achieved with the embodiment of the invention in which a movable boundary wall is provided in the inlet lock chamber.
- an outlet lock chamber is additionally provided which at least at times communicates with the inert gas atmosphere present in the drying chamber and at least at times from the normal atmosphere.
- the outlet lock lower chamber a movable boundary wall is provided.
- Figure 1 shows a detail from a painting system for vehicle bodies in vertical section
- FIGS 2 to 6 the plant section of Figure 1 in different operating phases.
- a section of a painting system which comprises a pre-dryer 204 and a main dryer 206.
- the latter in turn has an inlet lock 207 and a dryer tunnel 208.
- the vehicle bodies 202, freshly painted in a spray booth, not shown, are brought into the pre-dryer 204 from the left with the aid of a conveyor system, not shown in detail, and here from a large part of the solvent freed. From there they enter the inlet lock 207, which serves to separate the normal atmosphere prevailing outside the main dryer 206, that is to say also in the pre-dryer 204, from an inert gas atmosphere which is present in the main dryer 206.
- the vehicle bodies 202 After passing through the inlet lock 207 described in more detail below, the vehicle bodies 202 are moved through the drying tunnel 208 filled with inert gas and brought to a temperature between 40 ° C. and 150 ° C., the paint being cured. This is followed by an outlet lock, not shown, which can be constructed similarly to the inlet lock 207, but is reversed.
- the inlet lock 207 has a housing 213, which in an inlet chamber 214, a plunge pool 219 and an outlet chamber 215 is divided.
- the inlet chamber 214 is connected to the pre-dryer 204 via an opening 216 which can be closed by a roller door 217.
- the outlet chamber 215 communicates with the drying tunnel 208 via an opening 218, which can also have a roller door.
- the inlet chamber 214 is essentially in a normal atmosphere, the plunge pool 219 with an inert gas of higher density and the outlet chamber with an inert gas of lower density, preferably with the Density and temperature of the inert gas in the drying tunnel 208, filled.
- the densities are chosen so that the atmospheres in the various chambers 214, 215 and 219 of the inlet lock 207 only mix slightly.
- the direct atmosphere transfer from the inlet chamber 214 to the outlet chamber 215 is prevented by a vertical partition wall 222, which extends down to slightly below the floor level of the pre-dryer 204 or the drying tunnel 208.
- a transfer mechanism which moves the vehicle body series 202 through the inlet lock 207, comprises two lifting tables 240, 241, with each of which a support platform 242, 243 can be moved vertically up and down.
- the support platforms 242, 243 are in turn provided with conveyor systems which are compatible with the conveyor systems in the pre-dryer 204 or in the drying tunnel 208.
- a hood 244 is arranged to be vertically movable, the edges of which close tightly with the walls of the inlet chamber 214.
- the contour of the hood 244 is the contour of the vehicle body rie 202 closely adapted.
- the vehicle bodies 202 are moved through the inlet lock 207 in the following manner:
- the vehicle body As shown in Figure 1, the vehicle body
- the hood 244 is lowered from above and brought very close to the vehicle body series 202 (FIG. 2).
- the intermediate air is largely displaced to the outside via an outlet flap 260 provided in the hood 244.
- purging with inert gas can take place within the inlet chamber 215, which is directed against the vehicle body 202 via nozzles for this purpose.
- the amount of inert gas required in this connection is relatively small, since the volume to be flushed is considerably reduced due to the hood 244.
- the traq platform 242 of the lifting table 240 is lowered, as shown in FIG. 3.
- the vehicle body 202 is immersed in the dense inert gas which is located in the plunge pool 219.
- the support platform 242 of the lifting table 240 lies at the same height as the support platform 243 of the adjacent lifting table 241.
- the vehicle body 202 can thus, as can be seen from FIG. 4, be transferred from the lifting table 240 to the lifting table 241 .
- the support platform 243 of the lifting table 241 is raised so that the conveyor system of the support platform 243 reaches the same level as the conveyor system within the drying tunnel 208.
- the vehicle body 202 is lifted into the outlet chamber 215 of the lock 207, in which the hot inert gas atmosphere is present (cf. FIG. 5).
- the vehicle body 202 is extended into the dryer tunnel 208 in the direction of the arrow in FIG. 6.
- the support platform 242 of the lifting table 240 is raised again.
- the hood 244 also returns to its raised position so that the inlet chamber 214 of the inlet lock 207 can be charged with a new vehicle body 202.
