Abstract

The invention relates to a method for regenerating painted and/or primered panels, especially for regenerating shells of vehicles, especially automobiles. The aim of the invention is to provide a simple method for regenerating vehicle shells or panels with primer or paint defects. To this end, the panel or shell which has been coated with paint and/or primer is treated with a water jet to completely strip the coating. Alternatively, the outer layer or several outer layers only of the coating are completely removed using the water jet. Said water jet functions at a high pressure of at least 1000 bar, preferably 1500 bar to over 2800 bar.

Description

Die Erfindung betrifft eine Vorrichtung zur Regenerierung lackierter und/oder grundierter Bleche, insbesondere zur Regenerierung von Rohkarosserien von Kraftfahrzeugen, wobei das mit Lack und/oder Grundierung beschichtete Blech bzw. die damit beschichtete Rohkarosserie mittels Wasserstrahlbearbeitung vollständig von der Beschichtung befreit wird und die Wasserstrahlbearbeitung mit einem Hochdruck von mindestens 1000 bar erfolgt, wobei die Vorrichtung aus einer Kabine mit Seitenwänden, Dachwand und Stirnwänden besteht, die Stirnwände verschließbare Durchlaßöffnungen aufweisen, die Kabine von einem bodenseitig angeordneten Längsförderer durchsetzt ist, auf dem eine von Lackschichten zu befreiende Rohkarosse transportierbar ist, die durch die Durchlaßöffnungen in die Kabine bzw.. aus der Kabine bewegbar ist und die eine Hochdruckwasserzuleitung und deren Mündungen Wasserstrahldüsen aufweist, deren Düsenstrahl auf die von Lackschichten zu befreiende Fläche der Rohkarosse gerichtet ist.The invention relates to a device for the regeneration of painted and / or primed Sheets, especially for the regeneration of Body shells of motor vehicles, with the Paint and / or primer coated sheet metal or the body shell coated with it Water jet machining entirely from the Coating is freed and water jet machining with a high pressure of at least 1000 bar takes place, the device from a Cabin with side walls, roof wall and end walls exists, the end walls are lockable Have passage openings, the cabin of one longitudinal conveyor arranged at the bottom is on which one of the layers of paint to be removed Body shell can be transported through the Through openings in the cabin or .. from the cabin is movable and a high pressure water supply and whose mouths have water jet nozzles, the Nozzle jet on the layers to be freed of paint layers Surface of the body shell is directed.

Insbesondere bei der Herstellung von Kraftfahrzeugen, wie Personenkraftwagen oder dergleichen, besteht das Problem, daß nach der endgültigen Grundierung und Lackierung der Rohkarosserien Fehler an bestimmten Bestandteilen der Karosserie festgestellt werden und somit die Karosserie für den weiteren Fertigungsprozeß nicht brauchbar ist. Es sind dann relativ umständliche und kostenintensive Aufarbeitungsverfahren notwendig, um die Fehler in der Lackierung zu beseitigen, was sogar dazu führt, daß ganze Rohkarosserien oder Bestandteile davon verschrottet werden müssen, weil eine Regenerierung nicht lohnt.Especially in the manufacture of Motor vehicles, such as passenger cars or the like, there is a problem that after the final priming and painting of the Body shells Defects in certain components the body are determined and thus the Body for the further manufacturing process not is useful. Then they are relatively cumbersome and costly refurbishment processes necessary to correct the defects in the paintwork eliminate what even leads to whole Body-in-white or parts of it scrapped must be because regeneration is not worthwhile.

Aus der DE-A-4 315 633 ist eine gattungsgemäße Vorrichtung gemäß Oberbegriff des Anspruches 1 bekannt.DE-A-4 315 633 is a generic one Device according to the preamble of claim 1 known.

Aus der FR-A-2 630 667 ist es bekannt, eine Schutzschicht mit Wasserdrücken von 400 bis 1.200 bar zu entfernen.From FR-A-2 630 667 it is known a Protective layer with water pressures from 400 to 1,200 bar to remove.

Die EP-A-492 268 beschreibt die Entfernung von Lacken, wobei zunächst die Lackschicht des Werkstückes versprödet wird mittels eines tiefkalten Mediums und anschließend die Lackschicht mit Hochdruckwasserstrahlen entfernt wird.EP-A-492 268 describes the removal of Lacquers, first of all the lacquer layer of the Is embrittled by means of a workpiece cryogenic medium and then the paint layer is removed with high pressure water jets.

Die US-A-5 628 271 beschreibt ein Verfahren zur Entfernung von Lacken von Werkstücken mit Wasserdrücken von über 2.100 bar.US-A-5 628 271 describes a method for Removal of paints from workpieces with Water pressures of over 2,100 bar.

Ausgehend von dem gattungsbildenden Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung gattungsgemäßer Art zu schaffen, mit der in einfacher Weise eine Regenerierung von Rohkarosserien oder Blechen ermöglicht ist, die Fehler in der Grundierung oder Lackierung aufweisen. Based on the generic state of the Technology is the object of the invention, to create a device of the generic type, with the simple regeneration of Body-in-white or sheet metal is made possible Errors in the priming or painting exhibit.

Zur Lösung dieser Aufgabe wird vorgeschlagen, daß parallel zum Längsförderer, vorzugsweise beidseits daneben, Laufschienen angeordnet sind, auf denen programmierbare Roboteraggregate verfahrbar sind, die die Hochdruckwasserzuleitung mit den Wassersträhldüsen aufweisen, wobei die Düsen mäanderartig über die Fläche der von Lackschichten zu befreiende Rohkarosse geführt sind.To solve this problem, it is proposed that parallel to the longitudinal conveyor, preferably on both sides next to it, running tracks are arranged on which programmable robot units are movable, the the high pressure water supply with the Have water jet nozzles, the nozzles meandering over the surface of the layers of lacquer liberating body shell are performed.

Bei der Anwendung der erfindungsgemäßen Vorrichtung wird die kinetische Energie von Wasserstrahlen zur Trennung von Lackschichten und/oder Grundierungsschichten von Blechen oder von Rohkarosserien eingesetzt. Hierzu wird Wasser mit einer Hochdruckpumpe verdichtet und zur Wasserstrahldüse befördert. Aus dieser Düse tritt ein Freistrahl aus, der an der Kontaktstelle zum lackierten Blech seinen Impuls als Staukraft überträgt. Hierdurch wird eine hydromechanische Stofftrennung in der Weise bewirkt, daß die Lackierung und/oder Grundierung von dem Basisblech abgelöst und vollständig entfernt wird, so daß im Ergebnis ein völlig von Beschichtung befreites Blech bzw. eine völlig von Beschichtungen befreite Rohkarosserie zur Verfügung gestellt wird. Zur Erzeugung des Hochdruckes werden Hydrozylinder, insbesondere Plunger- oder Tauchkolbenzylinder eingesetzt. Mit der erfindungsgemäßen Vorrichtung können fehlerhaft lackierte Rohkarosserien oder dergleichen komplett von der Beschichtung befreit werden, so daß diese nach der Regeneration sofort wieder in den Produktionsablauf eingeführt werden können und erneut grundiert oder lackiert werden können.By means of the device according to the invention sheet metal coated with lacquer and / or primer or the body shell coated with it Water jet machining entirely from the Coating exempted, the High pressure water jet machining at least 1,000 bar, preferably 1,500 bar to over 2,800 bar. When using the device according to the invention is the kinetic Energy from water jets to separate Lacquer layers and / or primer layers from Sheets or used from body-in-white. For this water is compressed with a high pressure pump and transported to the water jet nozzle. Emerges from this nozzle a free jet from the contact point to painted sheet metal its impulse as a damaging force transfers. This makes a hydromechanical Separation in such a way that the Painting and / or priming of the base plate is detached and completely removed, so that in The result is a sheet that is completely free of coating or one completely freed from coatings Body-in-white is made available. to Generation of high pressure are hydraulic cylinders, especially plunger or plunger cylinders used. With the device according to the invention can incorrectly painted body shells or The like completely freed from the coating be so that this immediately after regeneration be reintroduced into the production process can be primed or painted again can.
