Benefits of technology

[0022] By means of a paint material ejection method, in particular an inkjet method, it may thus be possible to paint or repaint aircraft in a very short time in a painting line with the use of inkjet painting robots.
[0023] This results in important advantages to the manufacturer during initial painting, in particular because it may be as

Problems solved by technology

However, this method is time-consuming and expensive.
Furthermore, painting a finished aircraft, a process which frequently takes several days, is very cost-intensive because during this time the aircraft cannot yet commence operations.
Spraying the surface of an aircraft by means of spray guns requires a complex and expensive suction of solvents and aerosols.
This work is very labour-intensive, requires specially trained expert staff and has to be carried out in protective suits.
Furthermore, working in a pain

first embodiment

[0064] Below, with reference to FIG. 1, a painting arrangement 100 according to the invention is described.

[0065] The painting arrangement 100 comprises a fuselage 101 with a curved surface 102 to be painted and a painting device for painting the curved surface 102 of the fuselage 101.

[0066] The painting device of FIG. 1 comprises an inkjet device 103, i.e. an inkjet printing unit which is equipped for ejecting paint material. The inkjet device 103 comprises a first paint jet 106a for ejecting red paint,. a second paint jet 106b for ejecting yellow paint, and a third paint jet 106c for ejecting blue paint.

[0067] Furthermore, the painting device comprises a travelling element 105 and a semicircular guide rail 104, along which the travelling element 105 is movably attached. Thus the travelling element 105 can be moved along the guide rail 104, which according to FIG. 1 is semicircular in shape, so as to be able to scan different surface regions of the curved fuselage 101, or to prov...

second embodiment

[0072] Below, with reference to FIG. 2 a painting arrangement 200 according to the invention is described.

[0073] The painting arrangement 200 is arranged for painting a curved surface 202 to be painted of a rudder unit 201 of an aircraft. To this effect an inkjet device 203 comprising paint jets (not shown in FIG. 2) is moved along the curved surface 202 to be painted, and paint materials of different colours are ejected from the paint jets so as to apply a desired texture to the curved surface 202 to be painted. In a direction that is horizontal according to FIG. 2 the inkjet device can be slid along a first guide rail 204 by means of a first travelling element 206. Furthermore, the first guide rail 204 in two edge sections comprises a second travelling element 207 and a third travelling element 208, respectively which are attached to a second guide rail 205 so as to be slidable in vertical direction according to FIG. 2. Thus, by sliding the travelling elements 206 to 208 along the...

third embodiment

[0075] Below, with reference to FIG. 3 a painting arrangement 300. according to the invention is described.

[0076] The painting arrangement 300 is equipped for painting a curved surface region 102, to be painted, of a fuselage 101 shown in cross section in FIG. 3. To this purpose the painting arrangement 300 comprises an inkjet device 103 with a plurality of spray jets by means of which the surface 102 to be painted can be covered with paint. The inkjet device 103 is attached to a guide robot 301 which can be controlled by means of a control computer 302. The guide robot 301 can guide the painting arrangement 300 along the surface region 102 to be painted so that the paint jets of the inkjet device 103 scan the surface 102 to be painted and cover said surface with paint according to a predefinable sequence.

[0077] The control computer 302 controls not only the timing of the ejection of paint from each of the paint jets of the inkjet device 103 but also mechanical guidance of the inkj...

Abstract

A painting device for painting a curved surface (102) of an object (101), with a paint material ejection device (103), with a guide device (104, 105) and with a control device. The paint material ejection device (103) is designed for ejecting paint material. By means of the guide device (104, 105) the paint material ejection device (103) can be mechanically guided along a curved surface of an object. By means of the control device the paint material ejection device (103) and the guide device (104, 105) can be controlled in such a way that by means of guiding the paint material ejection device (103) along a predefinable path and by means of predefinable ejection of paint from the paint material ejection device (103) along the predefinable path a curved surface (102) of an object (101) to be painted can be painted.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the filing, date of U.S. Provisional Patent Application No. 60 / 609, 998 filed Sep. 15, 2004, the disclosure of which is hereby incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] According to the state of the art, aircraft are painted using a complex method. In this method the individual paint coats to be provided are applied in several working stages (up to eight stages and more). [0003] To apply logos, lettering and other visual effects it is in many cases necessary to spatially delimit those regions that need to be painted from those that do not need to be painted, and thus to stick a covering film on regions of an aircraft surface that do not need to be painted. This is necessary to obtain neat paint edges. However, this method is time-consuming and expensive. Furthermore, painting a finished aircraft, a process which frequently takes several days, is very cost-intensive because...
