Abstract

The auxiliary device for painting and drying plants has a pressure chamber (2) formed between the paint booth roof and filter cover and from which air is withdrawn via an additional fan (4) installed on the outside of the booth and fed to a ducting system which has a feed duct (8) which branches into two bends (10,10'). The branch ducts lead to nozzles (20-22) installed in the region of the side walls and through which the warmed air is directed at an angle downwards and inwards against the vehicle. The branch ducts are divided into individual zones (13-16) on the side of the filter cover.

Description

Die Erfindung betrifft eine Zusatzvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to an additional device according to the preamble of the claim 1.

Der Trend bei modernen Lackieranlagen geht in Richtung Wasserlacke. Dies bringt Probleme insbesondere deshalb mit sich, weil das im Lack befindliche Wasser durch Abtrocknen aus dem Lack entfernt werden muß, was in der Regel eine relativ hohe Verweildauer des zu lackierenden Objektes, insbesondere eines Fahrzeuges oder Fahrzeugteiles in der Lackierkabine erforderlich macht.The trend in modern painting systems is towards water-based paints. This brings Problems particularly with themselves because the water in the paint through Drying must be removed from the paint, which is usually a relatively high Dwell time of the object to be painted, in particular a vehicle or Requires vehicle part in the paint booth.

Das Entfernen von Wasser aus dem Lack und das schnelle Abtrocknen des Lackes aus den gespritzten Objekten läßt sich dadurch beschleunigen, dass an den lackierten Flächen eine hohe Luftturbulenz erzeugt wird, wodurch die Verweildauer von lackierten Objekten, z. B. Fahrzeugteilen, auf einen Wert von etwa 50 - 60% reduziert werden kann. Während beispielsweise bei herkömmlichen Lackierkabinen die Luftgeschwindigkeiten, die von der Filterdecke aus gegen das Fahrzeug gerichtet werden, etwa 0,2 bis 0,4 m/sec betragen, werden für die Zwecke vorliegender Erfindung Luftgeschwindigkeiten in der Größenordnung von 20 m/sec bevorzugt, die über Düsen gegen die zu trocknenden Fahrzeugteile gerichtet werden.The removal of water from the paint and the quick drying of the paint The sprayed objects can be accelerated by the fact that the painted Areas of high air turbulence is generated, reducing the length of stay painted objects, e.g. B. vehicle parts, reduced to a value of about 50 - 60% can be. While, for example, in conventional paint booths Air speeds directed towards the vehicle from the filter ceiling will be about 0.2 to 0.4 m / sec, will be more present for the purposes Invention air speeds in the order of 20 m / sec preferred that be directed against the vehicle parts to be dried via nozzles.

Aufgabe der Erfindung ist, die Zeitdauer für die Durchführung des Trocknungsvorgangs bei in Spritzkabinen lackierten Objekten entscheidend zu reduzieren und Lösungen zu finden, mit denen die Verweildauer erheblich verkürzt und die Effektivität verbessert werden kann.The object of the invention is the period of time for performing the Drying process for objects painted in spray booths decisively reduce and find solutions that significantly reduce the length of stay and the effectiveness can be improved.

Gemäß der Erfindung wird dies mit den Merkmalen des Kennzeichens des Anspruches 1 erreicht. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.According to the invention, this is done with the features of the characteristic of Claim 1 reached. Further refinements of the invention are the subject of Dependent claims.

Entscheidend für diese Erfindung sgemäße Lösung ist die Erzeugung einer hohen Luftturbulenz an den zu trocknenden Oberflächen eines lackierten Fahrzeuges oder eines entsprechenden Gegenstandes, damit der Lack möglichst schnell abtrocknet, d. h., dass überschüssiges Wasser möglichst rasch aus dem Lack entfernt wird und damit die Trocknungsdauer von Wasserlack soweit wie möglich herabgesetzt wird.Decisive for this solution according to the invention is the generation of a high one Air turbulence on the surfaces to be dried of a painted vehicle or a corresponding object so that the paint dries as quickly as possible, d. that is, excess water is removed from the paint as quickly as possible and thus the drying time of water-based paint is reduced as far as possible.

Hierzu wird der für den Trocknungsvorgang verwendete vorgewärmte Luftstrom über Luftdüsen gezielt gegen das zu trocknende Objekt gerichtet, und zwar mit einer Geschwindigkeit bzw. Intensität, die ein Vielfaches der Luftgeschwindigkeit beträgt, mit der bei herkömmlichen Lackieranlagen Luft über die Filterdecke gegen ein Fahrzeug gerichtet wird. Diese Zuluft hoher Intensität und Geschwindigkeit wird dadurch erzielt, dass Luft aus einem Druckraum zwischen Kabinendecke und Filterdecke über ein zusätzliches Gebläse, das z. B. außerhalb der Kabine angeordnet ist, angesaugt und über ein gesondertes Zuluftkanalsystem an die Luftdüsen transportiert wird, die im Kabineninneren an den Seitenwänden etwa im Bereich der vorhandenen Lampenröhren (knapp über den Lampen oder zwischen den Lampen) installiert sind. Das Gebläse fördert die dem Druckraum entnommene Luft über ein geschlossenes Zuluft-Rohrleitungssystem oder Zuluft-Kanalsystem, das z. B. im Druckraum oder über dem Druckraum angeordnet ist und über abgedichtete Druckleitungen und Druckkanäle an die Luftdüsen, die vom Rohrleitungssystem abzweigen, den Luftdüsen zugeführt wird. Die Luftdüsen können wahlweise unmittelbar unterhalb der Filterdecke und getrennt von den Lampenröhren angeordnet und an einen separaten, seitlichen Zuluftkanal angeschlosssen sein oder aber am Ausgang eines Zuluftrohres, das in die Lampenabschnitte voneinander trennenden Seitenwänden, die die Halterung und die Anschlüsse der Lampen aufnehmen, untergebracht sein. Die Düsen sind vorzugsweise an den Innenseitenwänden der Kabine oder in Ausnahmefällen auch an den Innenwänden der Vorder- und Rückwand der Kabine installiert.For this purpose, the preheated air flow used for the drying process is over Air jets aimed specifically at the object to be dried, with a Speed or intensity which is a multiple of the air speed, with the air against the filter ceiling in conventional painting systems Vehicle is directed. This supply air is of high intensity and speed achieved in that air from a pressure chamber between the cabin ceiling and Filter ceiling over an additional fan, the z. B. arranged outside the cabin is sucked in and via a separate supply air duct system to the air nozzles is transported in the interior of the cabin on the side walls approximately in the area of existing lamp tubes (just above the lamps or between the lamps) are installed. The fan conveys the air removed from the pressure chamber closed supply air piping system or supply air duct system, e.g. B. in Pressure chamber or is arranged above the pressure chamber and sealed Pressure lines and pressure channels to the air nozzles from the piping system branch off, the air nozzles is fed. The air nozzles can be optionally arranged immediately below the filter ceiling and separate from the lamp tubes and be connected to a separate, side supply air duct or on Output of a supply air pipe that separates into the lamp sections Side walls that accommodate the bracket and the connections of the lamps, be housed. The nozzles are preferably on the inside walls of the Cabin or, in exceptional cases, also on the inner walls of the front and rear walls installed in the cabin.

Das Rohrleitungssystem ist nach einer speziellen Ausführungsform der Erfindung in Bezug auf das Luftverteiler-Rohr-System in Zonen unterteilt, so dass die Rohrleitungen in den einzelnen Zonen unabhängig voneinander zu- und abgeschaltet werden können, je nach dem in der Kabine zu behandelnden Objekt. Entsprechend sind die Rohrleitungen an einzelne Zonen angeschlossen und andere nicht, oder die Rohrleitungen sind an alle Zonen angeschlossen. Die nicht benötigten Zonen können durch Verschlüsse, Klappen oder dergleichen von der Zuluftzufuhr abgetrennt werden, so dass bestimmte Düsen je nach dem gewünschten Effekt aktiviert werden können und andere nicht. Des weiteren kann die Blasrichtung der Düsen durch Einstellen der Düsenauslaßöffnung verändert werden, damit die Luftströmung in Form von Turbulenzen auf das jeweilige Objekt abgestimmt gerichtet und eine optimale Wirkung erzielt werden kann. Grundsätzlich sind entsprechend geeignete Düsen aus dem Stand der Technik bekannt, so dass sich eine nähere Beschreibung der Düsen selbst erübrigt.The piping system is according to a special embodiment of the invention in Regarding the air distribution pipe system zoned so that the pipes can be switched on and off independently of each other in the individual zones can, depending on the object to be treated in the cabin. They are accordingly Pipelines connected to individual zones and others not, or the Pipelines are connected to all zones. The zones not required can are separated from the supply air supply by means of closures, flaps or the like, so that certain nozzles can be activated depending on the desired effect and others don't. Furthermore, the blowing direction of the nozzles can be adjusted by adjusting the Nozzle outlet opening can be changed so that the air flow in the form of Turbulence directed towards the respective object and an optimal one Effect can be achieved. Suitable nozzles are always made known in the art, so that a more detailed description of the nozzles even unnecessary.
