Definitions
- Device for hardening a coating of an object consisting of a material that hardens under electromagnetic radiation, in particular of a UV lacquer, or of a thermally hardening lacquer
- the invention relates to a device for curing a coating of an object, in particular a vehicle body, consisting of a material that cures under electromagnetic radiation, in particular a UV lacquer or a thermosetting lacquer
- Varnishes that cure under UV light have hitherto been used mainly for painting sensitive objects, for example wood or plastic.
- These varnishes comes into play in particular that they can be polymerized at very low temperatures. This prevents the material of the objects from decomposing or outgassing.
- the curing of coating materials under UV light has other advantages which this coating method now interesting for use in other areas. In particular, this is the short curing time, which is directly reflected in a reduction in the length of the system, particularly in the case of coating processes which operate in a continuous process. This is associated with enormous cost savings.
- the device with which the gases to be introduced into the interior of the device are conditioned can be downsized, which also contributes to cost savings.
- the low operating temperature is also advantageous in the case of objects which, in and of themselves, could tolerate higher curing temperatures, in order to save energy, in particular thermal energy.
- lacquers have recently been developed which cure when exposed to heat in an inert gas atmosphere with the formation of very hard surfaces.
- the heat can be supplied in various ways, for example by convection or by infrared emitters. In the latter case, there are similar problems as described above for the use of radiators. In particular, all surface areas of the object to be painted should be guided past the infrared radiator at approximately the same distance.
- the object of the present invention is to design a device of the type mentioned at the outset in such a way that even coatings on complicatedly shaped, highly uneven objects, in particular vehicle bodies, can be cured with good results.
- the conveyor system comprises a hanging trolley which can be moved translationally on at least one track over the at least one spotlight, and in that on a chassis of the hanging trolley in the longitudinal direction one after the other two downwardly extending hanging brackets for hanging the Object are arranged, the length of which can be changed independently of one another by motor.
- the attached object is uniformly exposed to the amount and intensity of light required to cure the material.
- Complete hardening only occurs when the electromagnetic radiation hits the coating with an intensity above a threshold value on the one hand and on the other hand this intensity is maintained over a certain period of time. If the intensity is too low, a polymerization reaction does not start or only takes place incompletely; if the radiation is too short - even with sufficient intensity - also achieved incomplete curing.
- a particularly advantageous embodiment of the invention is characterized in that at least one of the hanging carriers comprises two bands or chains which can be rolled up independently of one another by motor and which engage on both sides of the object on a supporting structure which receives the object.
- the supporting structure receiving the object is suspended from three or, if both hanging carriers are designed in this way, from four points on the chassis of the hanging trolley.
- the supporting structure with the object fastened thereon can be pivoted not only about an axis running transversely to the route, but also about an axis running longitudinally of the route. This in turn makes it possible to also align side surfaces of the object with respect to lateral emitters in such a way that all surface areas in the area of action of the electromagnetic radiation generated by these emitters are cured evenly and completely.
- the conveyor system comprises a plurality of hanging carriages, each of which has its own drive unit for a translatory movement along the travel route.
- the hanging trolleys can transport the objects independently of one another and guide them past the at least one spotlight.
- the driving away z. B. include a rail, two rails or a roller conveyor, as is known per se in connection with such conveyor systems in the prior art.
- An embodiment of the invention is particularly preferred in which the device has a container which is arranged below the travel path and is open at the top, into the interior of which the object can be inserted by increasing the length of the hanging carrier and whose interior can be exposed to electromagnetic radiation from the at least one radiator is.
- This one. Container ensures that no electromagnetic radiation and no gases can escape in the lateral direction, which should be avoided for the operating personnel for health reasons.
- the hanging trolleys which are designed for immersing and immersing objects in liquid containers, unfold their advantages particularly well.
- the lowering into a container can be accomplished very easily with such hanging trolleys, since larger differences in height can also be bridged without any problems.
- the container can be designed as an independent part or as a correspondingly lined floor area of a cabin housing or the like.
- the arrangement of the emitters on or in the container can be different: So it is possible that at least one radiator is installed in a wall or in the bottom of the container. In three-dimensional curved surfaces of articles to be treated that this solution is preferred in which in the opposed, parallel to '
- Translational movement of the side walls and at least one radiator is installed in at least one of the two end walls perpendicular to the translational movement of the objects and in the bottom of the container. Then all sides or surface areas of the object can be easily reached by electromagnetic radiation.
- the radiators in which the radiators are arranged in the walls or in the bottom of the container, the radiators essentially form surface radiators.
- radiators which are designed as linear radiators.
- an embodiment of the invention is particularly advantageous in which a plurality of emitters in a U-shaped arrangement with two essentially vertical legs and one essentially horizontal Base are provided. The object to be treated is, so to speak, "threaded" between the vertical legs of the portal frame.
- the arrangement of the emitters on the essentially vertical legs can be adapted to the course of the side surfaces of the object. This enables a uniform and complete curing of the coating on the side surfaces of the object to be achieved even with curved side surfaces of the object.
- a protective gas can be supplied to the interior of the container.
- the protective gas has the primary function of preventing the presence of oxygen in the radiation region of the emitters, since oxygen can be converted into harmful ozone, in particular under the influence of UV light, and also impairs the course of the polymerization reaction.
- the protective gas should be heavier than air, as is the case with carbon dioxide, for example, so that the protective gas escapes from the open-topped container only slowly.
- the container is therefore filled with the heavy shielding gas in a similar way to a liquid.
- An inlet for the protective gas is preferably in the immediate vicinity of the at least one radiator. In this way, the protective gas can simultaneously have a cooling effect on the at least one radiator.
- At least one radiator is assigned a movable reflector on the side facing away from the object.
- the direction of the electromagnetic radiation generated by the at least one radiator can be influenced in a targeted manner. This makes it possible to enlarge the effective range of the electromagnetic radiation available.
- the container can be provided with a reflective layer on at least one inner surface. This allows spotlights with lower power to be used.
- the reflective effect is enhanced by the fact that the reflective layer is uneven. Under these circumstances, the reflections take place at very different angles, so that the interior of the container is very is moderately filled with electromagnetic radiation in a wide variety of propagation directions.
- the layer can consist, for example, of an aluminum foil. This has a very good reflectivity for electromagnetic radiation and is also very inexpensive. Bumps can be easily created by crumpling the aluminum foil.

- Figure 2 is an enlarged view of a portion of the curing device shown in Figure 1;
- FIG. 3 shows a cross section along the line III-III through part of the device shown in FIG. 1;
- Figure 4 shows another embodiment of a curing device in a representation corresponding to Figure 2;
- FIG. 5 shows the exemplary embodiment according to FIG. 4 in a representation corresponding to FIG. 3.
- a device for curing UN lacquers is shown in a greatly simplified and not to scale longitudinal section and is designated overall by 10.
- the curing device 10 shown as an example is part of a painting system which is provided to apply a multi-layer coating to pre-assembled vehicle bodies 12.
- the curing device 10 comprises a monorail conveyor system known per se for the vehicle bodies 12, which comprises an overhead rail 14 and hanging carriages 16 attached thereto. With the help of this overhead conveyor system, the vehicle bodies 12 are fed to the curing device 10 and transported through the individual stations of the curing device 10. These stations are a preliminary heating zone 18, an irradiation device 20 and a reheating zone 22.
- the preheating zone 18 and the post-heating zone 22 each contain heating devices indicated by 24 or 26 and designed as hot air heaters. Alternatively, heating by IR emitters or with the help of a magnetron can be used to generate microwaves.
- the preheating zone 18 can perform different functions depending on the type of coating material. If this material is solvent-based, for example water-based paint, the solvents are largely removed here. If it is powder material, the preheating zone 18 serves to gel the powder and in this way make it ready for polymerization.
- the irradiation device 20 comprises a cabin housing 28 which is designed in such a way that neither gas exchange with the surroundings nor leakage of UV light is possible.
- windows 32 are embedded in the side walls of the cabin housing 28, which are transparent to visible light but impermeable to UV light.
- the irradiation device 20 has an inlet lock 34 and an outlet lock 36, which the Hanging trolleys 16 with the vehicle body series 12 attached to them must pass when entering or leaving the interior 30.
- the inlet lock 34 and the outlet lock 36 are each designed as double locks with two movable roller doors 341, 342 and 361, 362, respectively. Because of the overhead rail 14, the roller doors 341, 342 and 361, 362 are rolled up from below in order to keep a passage slot for the rail 14 as short as possible.
- a trough-like container 38 Arranged in the interior 30 of the cabin housing 28 is a trough-like container 38 which can be filled with a protective gas, which is stored in a gas container 40 and can be introduced via a line 42 opening into the bottom of the container 38.
- the protective gas is carbon dioxide, since it is heavier than air in the gaseous state and thus behaves similarly to a liquid in the open-top container 38.
- the amount of protective gas supplied via line 42 is in dynamic equilibrium with the amount of protective gas which escapes, among other things, via inlet and outlet locks 34 and 36, respectively.
- the essentially cuboid-shaped container 38 has on its bottom surface 44, its side walls 39 running parallel to the conveying direction of the conveying system, designated 46, and also on its perpendicular to it End walls 41 on a plurality of UN emitters 48, which direct UN light into the interior of the container 38.
- the UV emitters which are arranged on the side wall 39 which can be seen by the viewer are only partially shown.
- the light exit surfaces of the UV emitters 48 are covered by an IR filter, so that only a small part of the heat radiation generated by the UV emitters 48 can get into the interior of the container 38.
- a large number of lines can also be provided, which open directly next to the UN radiators 48 on the walls of the container 38.
- the protective gas then flushes the parts of the UV radiator 48 that become hot during operation.
- protective gas can be directed specifically at vehicle bodies 12 immersed therein in the container in order to displace undesired residual gases containing oxygen which lead to the formation of ozone under the influence of UN light and can impair the polymerisation reaction.
- the interior 30 is connected to a regeneration circuit 42, which has the task of introducing oxygen, which is introduced into the interior 30 via the vehicle body series 12 or when the inlet lock 34 or the outlet lock 36 is opened, from the atmosphere prevailing in the interior 30 to remove.
- a regeneration circuit 42 which has the task of introducing oxygen, which is introduced into the interior 30 via the vehicle body series 12 or when the inlet lock 34 or the outlet lock 36 is opened, from the atmosphere prevailing in the interior 30 to remove.
- gas is continuously removed from the interior 30 via a line 43 and for example guided over a catalyst 45, which binds the oxygen catalytically. A part of this gas is returned to the interior 30 of the cabin housing 28 via a line 47, while another part is released into the outside atmosphere via a line 49.
- FIG. 2 it can be seen that the rail 14 of the overhead conveyor system is fastened to a ceiling structure, not shown, via anchors 16.
- the hanging carriage 16 comprises a chassis 50, which in turn consists of a platform 52 and drive groups 54a, 54b attached to it and extending upwards.
- the running groups 54a, 54b which can be seen particularly well in the cross-sectional illustration of FIG. 3, each contain an impeller 56 which can roll from above onto a horizontal leg 57 of the rail 14, which is essentially C-shaped in cross section.
- the impeller 56 can be driven by a drive unit 58 in the form of an electric motor.
- the vehicle body 12 can move in height in the direction indicated by an arrow 76, but also in the direction Longitudinal direction of the vehicle body 12 and pivoted in the transverse direction.
- the curing device 10 described above operates as follows:
- the UN emitters 48 are in operation, so that the entire interior of the container 38 is flooded with UV light, which is additionally reflected in a wide variety of directions by the crumpled aluminum foil 78 attached to the inner surfaces of the container 38 and on these Way is evened out.
- the UN radiators 48 are fed through the line 42 cooled gaseous carbon dioxide. The carbon dioxide gas which is only slightly preheated in this way enters the container 38 and fills it up from the bottom.
- the carbon dioxide emerging from the top of the container 38 which may be mixed to a slight extent with outgassing from the paint hardening on the vehicle body 12 and ozone, reaches the interior 30 of the cabin housing 28 and is sucked out from there via the outlet 43 , Suction can also take place directly on the upper edge of the walls of the container 38.
- the top lacquer layer is a clear lacquer that is applied as a powder to the already existing lacquer layers.
- the clear lacquer polymerizes under the influence of UV light and cures in this way.
- the prerequisite for this is that the powdered lacquer is first converted into a quasi-liquid, gel-like state.
- the preheating zone 18 is used for this purpose, in which a vehicle body 12 installed therein is heated to a temperature of approximately 90 ° C. At this softening temperature, the powder changes into the gel-like state mentioned.
- the vehicle body 12 After completion of the curing process in the container 38, the vehicle body 12 is raised again by the bands 70 being shortened evenly.
- the hanging trolley 16 with the vehicle body 12 is then fed via the outlet lock 36 to the reheating zone 22, in which a temperature of approximately 105 ° C. prevails. She lingers there
- a central controller is provided to control these processes, which is indicated by 90 in FIG.
- the Control 90 controls the individual servomotors within the curing device 10 and in particular the hanging trolley 16 via a bus system. Since such controls for hanging trolleys are known in principle in the prior art, details of the bus system etc. waived.
- spatial shape data of the vehicle body 12 are stored in a memory 92, which are required to store the vehicle body 12 in the container 38 in the manner described above along the
- This spatial shape data can e.g. B. can be accessed from a higher-level data processing system, in which relevant data such as type and color of the paint finish and body type and shape are stored for all vehicle bodies 12 passing through the curing device 10. All that is then required is a reading device which recognizes the type of vehicle body 12 entering the radiation device 20, so that the spatial shape data associated with this type can be called up.
- the measuring device 94 has a U-shaped frame, on which a plurality of optical scanners 96 with infrared light sources both in the vertical direction and transversely to Delivery direction 46 are attached.
- the optical scanners 96 record the outer contour of the vehicle body 12 as it passes through the measuring device 94.
- FIGS. 4 and 5 show an alternative exemplary embodiment for the container 38 and the UN emitters 48 arranged therein in representations based on FIGS. 2 and 3.
- the alternative embodiment differs from the one described above only in that UN radiators 48 are not distributed over the entire inner surface of the container 38, as is the case with the embodiment shown in FIGS. 1 to 3. Instead, there is a U-shaped arrangement of a total of six linear UV lamps 48 'in a longitudinally elongated container 38', which are articulated in pairs and can be adapted to the cross-section of the vehicle body 12 via hydraulic adjustment elements 100 , In this exemplary embodiment, the vehicle body series 12 is initially also let into the container 38 'in the vertical direction.
- the measuring station 96 can also be arranged in the conveying direction 46 directly in front of the UV emitters 48 '. Around- If the measuring station 96 detects about one or more light barriers in this case, when the vehicle body 12 comes into the detection range of a light barrier, a corresponding evasive movement of the vehicle body 12 can be initiated in real time by changing the length of the straps 70.
- the above exemplary embodiments are used for curing lacquers under UN light. However, they can also be used in coatings which cure under the action of heat, in particular in an inert gas atmosphere, for example in a CO 2 or nitrogen atmosphere. In this case, essentially only the UN radiators described need to be replaced by IR radiators. Other structural adaptations associated with the change in electromagnetic radiation are known to the person skilled in the art and need not be explained in more detail here.
