Definitions
- the invention relates to a method for coating, in particular for painting, of objects, in which the coating material is conveyed to an application device and delivered by the latter in powder form,
- the powder coating in particular the painting of objects and here again in particular the painting of vehicle bodies has been gaining increasing interest in recent years. A particularly important reason for this is the environmental friendliness, since the powder coating does not produce solvents, the disposal of which is often associated with great expenditure on equipment. Despite this great, obvious advantage, the powder coating is currently used only limited.
- Object of the present invention is to provide a method and an installation of the type mentioned, which allow even with a frequent change of the coating material, in particular the color of the paint powder used, a rational, cost-effective coating.
- this object is achieved in that the coating material is conveyed in at least part of the route to the application device in an abrasion-resistant powder container to which the powdery coating material is removed only in the vicinity of the application device.
- the coating material is not conducted as free powder over at least the largest part of its conveying path, which could contaminate this conveying path. Rather, the coating material is transported in an abrasion-resistant powder container, which leaves no "traces" in the form of powder and therefore makes no cleaning of the conveyor line required.
- the amount of coating material which requires an application device for a complete coating process for a particular article is weighed out and transported overall in a powder container.
- powder containers which have a capacity approximately of 2000 g of coating material.
- Another advantage of using comparatively small portions of coating material is that the total amount of coating material applied to the application device can be determined by counting the conveyed powder containers. The smaller the powder container, the more accurate the required total amount of coating material can be dosed.
- the capacity for coating material is less than 50 g, preferably less than 20 g.
- the powder container may in particular consist of plastic or metal, that is, of a material that is inert, inexpensive and easy to break up.
- these powder containers can be ground to remove the coating material and release together with the coating material on the application device, so that no separate disposal is required.
- the feeding device is designed so that it can transport the powdery coating material in the interior of powder containers made of abrasion-resistant material;
- an opening device is provided at the end of the feed device facing the application device, which openings open the powder containers and the interior of which can remove the pulverulent coating material for forwarding to the application device (6).

- a "colorful series” of vehicle bodies 5 is to be painted.
- a “colorful sequence” is meant a series of vehicle bodies 5 which are different types requiring different amounts of paint and which are to be painted in different colors.
- the system controller knows at each point in time, at which point the individual vehicle bodies 5 are located and in which way they are to be painted. This knowledge is obtained by the system control either by automatic programming and transfer of the data from a previous processing station or by reading the data from a carried with the vehicle body 5 data carrier at a certain distance in front of the painting booth 2 or by manual programming.
- the system controller has constantly tracked and ensured the position of the vehicle body 5 on the conveyor system 4, that the vehicle body 5 arrives at the same time in the painting booth 2, to which the paint powder container 22 belonging to this vehicle body 5 is also located in the docking station 5 of the removal carousel 19.
- the arm of the robot 20 now lifts off with the paint powder container 22 from the docking station 5 of the removal carousel 19 and begins the waiting vehicle body 5 to paint in a known manner.
- the arm of the robot 20 After completion of the work, the arm of the robot 20 returns to the docking station 5 of the removal carousel 19 and returns the largely emptied paint powder container to the waiting receptacle 36.
- the emptied Farbpulbewe conceptioner 22 moves in the further rotation of the removal carousel 19 in the position 8, where it passes through the lock 39 in the line 18 and from there back to the charging carousel 16.
- the paint powder containers 22 were so large that they can absorb the entire quantity of paint powder comprising an application device 6 for painting a vehicle body
- the paint powder containers 22 have a comparatively small size, so that they have for example, only a few 10 g can record. They behave similarly to a bed and can be transported through a supply line similar to a pig.
- Components of the second embodiment of a paint shop which correspond to those of the first embodiment, are designated by the same reference numerals plus 100.
- the paint shop 101 shown in Figure 9 is constructed substantially symmetrically to its center plane; It is therefore sufficient to describe below only the half shown in FIG. 9 to the right of the median plane.
- the application device 106 guided by the robot 120 sprays lacquer in powder form onto the vehicle body 105.
- Each half of the painting installation 101 has a paint supply device provided overall with the reference numeral 110. This includes several, shown in the
- Example two storage containers 111 which are loaded with powder containers.
- the powder containers of the two storage containers 111 contain varnish powder of different colors.
- Each powder container contains a relatively small powder portion, so that the complete painting of the
- Vehicle body a variety of such powder container is needed. Their size is about the size of rinsing tablets currently on the market.
- the powder container itself consist of clear lacquer material or binder, that is to say of a neutral material which is contained in the lacquer powder in any case or which is compatible with it in the applied lacquer layer.
- the powder containers come from the interior of the storage container 111 in each case in a horizontally arranged, motor-driven guide screw 150 and are supplied from this individually to a lower outlet 151.
- the outlets 151 are located above the hopper of a weighing device 152. This is connected via a movable slide 153 with the inlet of a spiral conveyor 154 (see Figure 10).
- the outlet of the spiral conveyor 154 is in turn connected to a supply line 117, which leads to a grinding mill carousel 119. This is arranged in the immediate vicinity of the robot 120 as close as possible to the application device 106.
- a storage container 155 which contains so-called separating body.
- These separators may have the same shape as the powder containers, but have a property that makes it possible to determine their position in a line or a hose without contact from the outside.
- the separating bodies can have special mechanical, magnetic or optical properties in which they differ from the powder containers. For example, they may have a different density, a different color, or a light-transmissive aperture.
- a controllable flap 156 At the lower end of the reservoir 155 is a controllable flap 156, through the outlet, the separating body can be dispensed individually into the weighing device 152.
- the grinder carousel 119 is shown in a very schematic manner in plan view in FIG. It comprises three grinders 119a, 119b, 119c, which are motorized at an angular distance of 120 ° from one another in an axis around its axis rotatable cylindrical revolver 119d are mounted.
- the grinder carousel 119 is disposed outside of the paint booth 102 bounded by a side wall 121.
- the grinder 119 a is located in a charging point in which it is connected to the supply line 117.
- the grinder 119b is located in a cleaning location where it can be blown out with compressed air or otherwise cleaned.
- the grinder 119c finally assumes a working position in which it is connected via a hose 157 to the application device 106.
- the paint shop 101 described above operates as follows:
- the reservoir 11 are filled with powder containers.
- the transport screw 150 of the storage container 111 containing the correct powder container now starts to work and dispenses such a number of powder containers into the weighing device 152 until the weight corresponding to the required amount of paint has been reached.
- the slider 153 of the weighing device 152 is opened; the powder containers are introduced by the spiral conveyor 154 in the supply line 117 and conveyed through this in any way to the grinder 119a of the grinder carousel 119.
- a connection 158 for the pushing medium In the vicinity of the spiral conveyor 154, a connection 158 for the pushing medium (see FIG.
- the powder containers pass through the supply line 117, which can have a considerable length, without significant abrasion, ie, without appreciable contamination of the feed line 117.
- the grinder carousel 119 is rotated in Figure 11 by 120 ° counterclockwise.
- the grinder 119a fed with powder containers reaches the working position, which had previously been occupied by the grinder 119c.
- the grinder 119c rotates to the cleaning point, which is taken in Figure 11 by the grinder 119b.
- the latter grinder 119b occupies the loading point, which has the grinder 119a in FIG.
- grinder 119a which is loaded with powder containers, now begins to pulverize the powder container, thereby exposing the paint powder located inside.
- the material of the powder container itself is also powdery and mixed with the paint powder.
- the grinder 119a serves as an "opening device" for the powder container.
- the resulting powder mixture which consists predominantly of paint powder, for a smaller part of the neutral, material of the powder container, is now supplied via the tube 157 of the application device 106, which can begin with the painting process.
- the painting process is completed, so all coated areas of the vehicle body 105 are coated, the supply of powder containers within the grinder 119a is consumed to a small excess.
- the grinder 119b which is now ⁇ more in the position of the grinder 119a of FIG. 3, has been refilled with powder containers whose weight again corresponds to the quantity of paint powder needed for the next vehicle body 105 to be painted.
- a color change is carried out by placing a separating body in the weighing device 152 on the last powder container containing the "old" paint by briefly opening the outlet flap 156 of the storage container 155. Then, the feeding of the weighing device 152 is continued with a different color containing powder containers from the other reservoir 111.
- a detector 159 In the vicinity of the feed point of the grinder carousel 119 is a detector 159, which is able to recognize the characteristic property of the separating body, that is their deviating optical, mechanical or magnetic property, and thereby detect when the last the " old "color containing powder container happens and therefore the rotation of the mill carousel 119 is to initiate.
- a cleaning of the supply line 117 is in this color Change normally not required.
- the previously active grinder 119a, 119b, 119c is cleaned in the position of the grinder-carousel 119, which is taken in Fig. 11 by the grinder 119b, for example by blowing.
- the very short powder flow paths in the tube 157 are cleaned between the grinder in the working position and the application device 106. This compared to the prior art minor cleaning work can be done very quickly and easily.
- the separating body can be discharged at the grinder carousel 119 and returned to the reservoir 155. However, they can also be ground and sprayed via the application device 106 if they consist of a material suitable for this purpose, for example, binder or clearcoat material.
- powder containers are used, each filled with a weight of a few tens of grams. In principle, however, it is also possible to use smaller "units".
- the powder container can basically have any shape. In question are in particular spherical shape, cylindrical shape or dragee; the choice of the form in each case takes place taking into account the paint material, the way the powder container is conveyed and the way in which the powder containers are reopened.
- the opening of the powder container can be done in other ways than by the above-mentioned grinders 119a, 119b, 119c. So it is basically possible to cut open the powder container and to remove in this way the paint powder contained therein. The cut containers are then disposed of.
- FIG. 13 shows in a very schematic way an application device 106 into which a grinder 119 is integrated.
- an air turbine 161 the compressed air can be supplied via a rear compressed air connection 162 and is thus set in rapid rotation.
- the grinder 119 which has a conically forwardly tapered grinder housing 163.
- a screw conveyor 164 is rotatably mounted, the worm threads are lower and narrower towards the front end.
- the screw conveyor 164 is rotatable by a motor 165.
- the filled powder containers coming from the tube 157 (see Figures 9 and 12) enter via an inlet 166 at the rear, larger diameter end of the grinder housing 163.
- the application device 106 operates as follows:
- the powder containers are fed via the input 166 to the further region of the grinder housing 163, where they are detected by the conveyor screw 164 and transported in the direction of the narrower, front end of the grinder housing 163. Due to the geometry of the screw conveyor 164 and the grinder housing 163, the powder containers themselves are pulverized and release the paint powder they contain. The resulting powder mixture is at the front, open end of the grinder housing 163 in the schematically illustrated
- both the grinder 119 and the turbine 161 are driven by the same engine.
