Description

Die Erfindung betrifft ein Verfahren zur Reinigung eines Gegenstandes, insbesondere einer Fahrzeugkarosserie.The invention relates to a method for cleaning an object, in particular a vehicle body.

In der Industrie tritt häufig das Problem auf, daß Gegenstände gereinigt werden müssen. Insbesondere ist es erforderlich, Gegenstände vor einer Lackierung von Schmutzpartikeln zu befreien. Da der Grad der Reinigung die Qualität der Lackierung wesentlich beeinflußt, muß die Reinigung der Gegenstände mit großer Sorgfalt erfolgen.The problem often arises in industry that items have to be cleaned. In particular, it is necessary to paint objects before Free dirt particles. Because the degree of cleaning the quality of the paint The items must be cleaned with great care.

Deshalb wird bei der Reinigung von Kraftfahrzeugkarosserien ein relativ großer Aufwand bei der Reinigung betrieben. So werden Kraftfahrzeugkarosserien einem aus unterschiedlich gerichteten Düsen stammenden Luftstrom unterzogen. Hierdurch werden im wesentlichen die sich im Inneren der Karosserie befindlichen Schmutzpartikel ausgeblasen. Zum Reinigen der äußeren Teile der Karosserie wird die Karosserie mit aus Straußenfedern bestehenden Bürsten behandelt.Therefore, cleaning car bodies is a relatively large effort operated during cleaning. So motor vehicle bodies become one air flow coming from differently directed nozzles. This will essentially the dirt particles located inside the body blown out. To clean the outer parts of the body, the body is used Brushes made of ostrich feathers are treated.

Wenngleich mittels des bekannten Verfahrens eine Kraftfahrzeugkarosserie auch im wesentlichen zufriedenstellend gereinigt werden kann, so hat das bekannte Verfahren dennoch den Nachteil, daß insbesondere sich in Ecken oder Nischen befindliche Schmutzpartikel häufig nicht entfernt werden können. Des weiteren lassen sich fest an der Karosserie haftende Schmutzpartikel ebenfalls häufig mittels des bekannten Verfahrens nicht entfernen.Although using the known method, a motor vehicle body also in can be cleaned substantially satisfactorily, so the known method nevertheless the disadvantage that there are in particular in corners or niches Dirt particles often cannot be removed. Furthermore, can be firmly  dirt particles adhering to the body also frequently by means of the known Do not remove the procedure.

Aus der DE 196 16 502 A1 ist ein Verfahren zur Oberflächenbehandlung bekannt, bei welchem Gegenstände von einem Transportmittel aufgenommen und in ein Tauchbad eingetaucht werden. Während und/oder unmittelbar nach dem Tauchvorgang werden die Gegenstände in Schwingungen versetzt. Die Schwingungen liegen oberhalb von 0,2 Hz bis maximal 1 KHz und haben eine maximale Amplitude von 5 Zentimetern, insbesondere maximal 10 Zentimetern.A method for surface treatment is known from DE 196 16 502 A1 which objects are picked up by a means of transport and placed in an immersion bath be immersed. During and / or immediately after the dive the objects vibrated. The vibrations are above 0.2 Hz up to a maximum of 1 kHz and have a maximum amplitude of 5 centimeters, in particular a maximum of 10 centimeters.

Es ist Aufgabe der Erfindung ein Verfahren zur Reinigung eines Gegenstandes anzugeben, welches sehr effektiv ist.The object of the invention is a method for cleaning an object indicate which is very effective.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to this problem results from the characteristics of the characterizing part of claim 1. Advantageous further developments of the invention result from the Dependent claims.

Gemäß der Erfindung wird der Gegenstand in Schwingung versetzt. Es hat sich überraschend gezeigt, daß durch das in Schwingung versetzen des Gegenstands Schmutzpartikel aus Ecken oder Nischen heraustransportiert werden. Des weiteren werden durch die Schwingungen fest an dem Gegenstand haftende Schmutzpartikel gelöst.According to the invention, the object is vibrated. It has surprisingly shown that by vibrating the object Dirt particles can be transported out of corners or niches. Furthermore due to the vibrations, dirt particles adhere firmly to the object solved.

Als besonders vorteilhaft hat sich herausgestellt, den Gegenstand in Schwingungen mit einer Frequenz von 0,1-100 Hz zu versetzten, wie dies bei einer besonderen Ausführungsform der Erfindung vorgesehen ist. Des weiteren hat sich als besonders vorteilhaft erwiesen, daß die Schwingungen eine Amplitude von 0,1-70 Millimetern haben.It has been found to be particularly advantageous to vibrate the object a frequency of 0.1-100 Hz, as is the case with a special one Embodiment of the invention is provided. Furthermore, it has turned out to be special  proved advantageous that the vibrations have an amplitude of 0.1-70 millimeters to have.

Als besonders vorteilhaft hat sich auch eine Ausführungsform der Erfindung herausgestellt, bei der der Gegenstand über seine Transportmittel in Schwingungen versetzt wird. Hierdurch wird es auf besonders einfache Weise ermöglicht, den Gegenstand in Schwingungen zu versetzen. Des weiteren kann der Gegenstand beispielsweise auf dem Transport zu einer Lackierstation in Schwingungen versetzt und dadurch gereinigt werden.An embodiment of the invention has also been found to be particularly advantageous highlighted in which the object vibrates through its means of transport is transferred. This makes it possible in a particularly simple manner To vibrate the object. Furthermore, the object for example vibrated during transport to a painting station and thereby be cleaned.

Besonders vorteilhaft ist es auch, wenn sich der Gegenstand während des Schwinggins in einem Luftstrom befindet. Hierbei ist es besonders vorteilhaft, wenn der Luftstrom aus mehreren Düsen stammt, welche individuell anordenbar sind. Durch den Luftstrom wird der durch die Schwingungen erzeugte Reinigungseffekt noch verstärkt. Durch die Kombination von Luftstrom und Schwingen des Gegenstandes wird eine besonders effektive Reinigung erreicht. Da sich die Schmutzpartikel im wesentlichen durch das Schwingen des Gegenstandes von dem Gegenstand lösen, braucht der Luftstrom im wesentlichen nur noch zum Abtransport der Schmutzpartikel verwendet zu werden. Durch das gezielte Versetzen der Fahrzeugkarosserie in Schwingungen werden Schmutzpartikel heraustransportiert beziehungsweise gelockert und mit Luftunterstützung aus der Karosserie entfernt. Hierdurch werden beispielsweise Nacharbeiten im Lackierprozeß verringert.It is also particularly advantageous if the object is in motion during the vibrating process is in an air stream. It is particularly advantageous here if the air flow is off comes from several nozzles, which can be arranged individually. Through the air flow the cleaning effect generated by the vibrations is further enhanced. Through the Combination of air flow and swinging of the object becomes a special one effective cleaning achieved. Since the dirt particles essentially by the To loosen the swing of the object from the object, the air flow in the essentially only to be used to remove the dirt particles. By setting the vehicle body in vibration Dirt particles transported out or loosened and with Air support removed from the body. This will, for example Rework in the painting process reduced.

Durch das erfindungsgemäße Verfahren lassen sich insbesondere Fahrzeugkarosserien sehr gut reinigen. Durch das gezielte Versetzen der Fahrzeugkarosserie in Schwingungen wird ein sehr hoher Reinigungsgrad der Fahrzeugkarosserie erreicht. Das Verfahren kann überall dort, wo im Arbeitsablauf grober oder feiner Staub entsteht wie beispielsweise nach Schleifarbeiten in einer Lackiererei eingesetzt werden. Mittels des erfindungsgemäßen Verfahrens können aber auch Schweißreste im Rohbau oder Restpulver in der Pulverlackierung entfernt werden.The method according to the invention can be used in particular for vehicle bodies clean very well. By deliberately moving the vehicle body in Vibrations a very high degree of cleaning of the vehicle body is achieved. The process can be used wherever coarse or fine dust is created in the workflow  such as used in a paint shop after grinding work. Means The process according to the invention can also be used for welding residues in the shell or Residual powder in the powder coating can be removed.

Durch das erfindungsgemäße Verfahren wird eine Verringerung der Nacharbeit beispielsweise in der Lackiererei erreicht. Des weiteren ergibt sich durch das erfindungsgemäße Verfahren eine Verminderung von Schmutzverschleppung. Darüber hinaus läßt sich durch das erfindungsgemäße Verfahren eine Standzeitverbesserung von Spülbädern erreichen.The method according to the invention reduces reworking achieved in the paint shop, for example. Furthermore, it results from the Process according to the invention a reduction of carryover of dirt.
