Description

Die Erfindung richtet sich auf eine Vorbehandlungsanlage zur Sprüh-Vorbehandlung von in einer nachgeordneten Beschichtungsanlage zu beschichtenden Gegenständen, wobei jeweils eine Mehrzahl derartiger Gegenstände und Halteeinrichtung an einer Transporteinrichtung angeordnet ist und von der Transporteinrichtung taktweise nacheinander einer Mehrzahl von Sprüh-Vorbehandlungseinrichtungen mit Auffangwannen für das Behandlungsmedium zugeführt wird, wobei die Auffangwannen unmittelbar benachbart zueinander angeordnet sind, und wobei im Bereich der Kanten zwischen zwei Auffangwannnen eine unter Freigabe des Transportweges aus diesem herausbewegbare Trenneinrichtung vorgesehen ist.The invention is directed to a pretreatment system for spray pretreatment of those to be coated in a downstream coating system Objects, each with a plurality of such objects and holding device arranged on a transport device is and of the transport device successively a plurality of spray pretreatment devices with drip pans for the Treatment medium is supplied, the drip pans immediately are arranged adjacent to each other, and being in the area of Edges between two drip pans one with clearance of the transport route separating device which can be moved out of this is provided.

Eine derartige Vorbehandlungsanlage wird in EP 0 505 694 beschrieben. Dort sind Trennelemente in Form von gegenüber schwachen Laugen und Säuren beständigen Vorhängen bzw. Rollos vorgesehen. Diese Trennelemente sind mit ihrer Unterkante mit dem Bereich zwischen zwei Auffangwannen bzw. mit dem Randbereich der jeweils äußersten Auffangwanne verbunden. Aufwickelwellen sind mit dem entgegengesetzten Endbereich der Trennelemente verbunden und ihrerseits im Bereich der Decke über Seilzüge gelagert. Die Enden der Wickelwellen sind jeweils an einem horizontalen Träger drehbar angeordnet, wobei die jeweils beiden horizontalen Träger an einer Halteeinrichtung beiderseits geführt sind und mittels eines Seilzuges und eines zugeordneten Motors anhebbar und absenkbar sind.Such a pretreatment plant is described in EP 0 505 694. There are separators in the form of weak alkalis and Acid-resistant curtains or blinds are provided. These dividers are with their lower edge with the area between two sumps or with the edge area of the outermost drip pan connected. Wind-up shafts are with the opposite end area the separating elements connected and in turn in the area of the ceiling Cables stored. The ends of the winding shafts are each on a horizontal Carrier rotatably arranged, the two horizontal Carriers are guided on both sides of a holding device and by means of a Cable and an associated motor can be raised and lowered.

Weiterhin sind im Bereich jeder Wanne Sprühdüsen angeordnet, welche an einer rechteckigen, ringförmig geschlossenen Leitung ausgebildet sind, wobei jede Leitung einen zentralen Zufluß aufweist. Die Ringleitungen sind über außerhalb der jeweiligen Wanne vorgesehene Lager an Halteeinrichtungen mittels motorischer Antriebe in vertikaler Richtung verfahrbar, so daß die zu behandelnden Gegenstände in vertikaler Richtung gesehen von allen Seiten besprüht und auf diese Weise Sprühschatten vermieden werden.In addition, spray nozzles are arranged in the area of each tub, which on a rectangular, annularly closed line are formed, wherein each line has a central inflow. The ring lines are via bearings provided on holding devices outside the respective tub can be moved in the vertical direction by means of motor drives, see above that the objects to be treated viewed in the vertical direction sprayed on all sides and in this way spray shadows can be avoided.

Solche Vorbehandlungsanlagen haben sich in der Praxis außerordentlich bewährt, weil sie einen sehr kompakten, platzsparenden Aufbau ermöglichen und auch eine wirtschaftliche Vorbehandlung vergleichsweise kleiner Chargen möglich ist.Such pretreatment systems have proven themselves in practice proven because they enable a very compact, space-saving construction and also economically pretreatment is comparatively smaller Batches is possible.

Die ursprünglich vorgesehenen folienartigen Trennelemente können bei manchen Anwendungsfällen den Nachteil aufweisen, daß beim Aufwickeln die beiden Folienseiten miteinander in Berührung kommen, so daß es beispielsweise bei der Abtrennung von sauren gegen basische Bäder zu Reaktionen, also z.B. einer Salzbildung, kommt, so daß sich Ablagerungen ausbilden können und die Funktionsfähigkeit beeinträchtigt wird.The originally intended film-like separating elements can be used for some applications have the disadvantage that when winding the two sides of the film come into contact with each other, so that for example in the separation of acidic versus basic baths to reactions, e.g. e.g. salt formation, so that deposits form can and the functionality is impaired.

Zur Vermeidung dieser Problematik ist es aus DE 29 717 515 UI bekannt, die Trenneinrichtungen ziehharmonikaartig zusammenfaltbar auszubilden, wobei bei diesem Zusammenfalten die einzelnen ziehharmonikaartig verbundenen Trennelementabschnitte jeweils nur so gegeneinander zu liegen kommen, daß eine Berührung zwischen Trennelementen, die unterschiedlichen Bädern zugewandt sind, vermieden wird. Unabhängig von dieser Ausgestaltung der Trennelemente ist es gemäß diesem Stand der Technik aber ebenfalls noch vorgesehen, daß Sprühdüsen gesondert angeordnet und angetrieben sind. To avoid this problem it is known from DE 29 717 515 UI to design the separating devices to be foldable like an accordion, with this folding the individual accordion-like connected Separator sections only to lie against each other that come into contact between separating elements that are different Baths are avoided. Regardless of this It is the design of the separating elements according to this prior art but also also provided that spray nozzles are arranged separately and are driven.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Anlage der in Betracht stehenden Art noch kompakter, einfacher und kostengünstiger aufzubauen.Proceeding from this, the object of the invention is a plant of the type under consideration even more compact, simple and inexpensive build.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in die Trennelemente eine Sprühdüsenanordnung integriert ist, die zusammen mit den Trennelementen anhebbar und absenkbar ist.This object is achieved in that in the separating elements a spray nozzle arrangement is integrated, which together with the Separating elements can be raised and lowered.

Dabei ist vorzugsweise vorgesehen, daß die Sprühdüsen über die Höhe und Breite der Trennelemente weitgehend gleichmäßig verteilt sind, um auf diese Weise eine möglichst gleichmäßige Besprühung zu gewährleisten. Die Sprühdüsen können während des Sprühvorgang - wie dies herkömmlicherweise der Fall ist - trotzdem noch mit kleiner Amplitude auf- und abbewegt werden.It is preferably provided that the spray nozzles over the height and Width of the dividing elements are largely evenly distributed to in this way to ensure the most uniform possible spraying. The spray nozzles can be used during the spraying process - as is conventional the case is - still moving up and down with a small amplitude become.

Günstigerweise sind Sprühdüsen auf beiden Seiten der Trenneinrichtung angeordnet, wenn die Trenneinrichtung nicht randseitig, sondern zwischen zwei benachbarten Wannen angeordnet ist.Favorably, spray nozzles are on both sides of the separating device arranged when the separator is not on the edge, but between two adjacent tubs is arranged.

Bei einer bevorzugten Ausführungsform sind die Trenneinrichtungen aus einer Mehrzahl von horizontal verlaufenden, ziehharmonikaartig über Gelenke verbundenen Lamellen gebildet.In a preferred embodiment, the separators are off a plurality of horizontal, accordion-like over joints connected slats formed.

Diese können mit einem Überzug, z.B. eine Kunststoff-Folie versehen sein, welche einerseits die Leitungen für die Spritzdüsen und die Spritzdüsen festlegt und andererseits gleichzeitig auch die gelenkige Verbindung zwischen den Lamellen herstellt. These can be covered with a coating, e.g. be provided with a plastic film, which on the one hand the lines for the spray nozzles and the spray nozzles defines and on the other hand also the articulated connection between the slats.

An den einzelnen Lamellen können seitlich abwechselnd auf der einen und der anderen Seite Stäbe befestigt sein, die dafür sorgen, daß beim Einfahren der Trenneinrichtung eine definierte, saubere Faltung stattfindet.On the individual slats, alternately on the one side and the other side rods are attached, which ensure that when retracting the separation device a defined, clean folding takes place.

Eine in der Zeichnung dargestellte Vorbehandlungsanlage umfaßt eine Mehrzahl von Auffangwannen 1, wobei in der Zeichnung der Einfachheit halber nur vier Wannen 1a bis 1d dargestellt sind, obwohl für die meisten praktischen Anwendungen mehrere derartige Wannen, z.B. sieben solcher Wannen vorgesehen sind.A pretreatment system shown in the drawing includes one A plurality of sumps 1, being in the drawing of simplicity only four tubs 1a to 1d are shown, although for most practical applications of several such tubs, e.g. seven such Tubs are provided.

In der Praxis kann z.B. eine erste Wannen zum Beiz-Entfetten mittels einer schwach alkalischen Lösung, eine zweite Wanne zum Spülen mit Wasser, eine dritte Wanne zum Dekapieren (Neutralisieren) für schwache, z.B. 10%-ige Schwefelsäure, eine vierte Wanne zum Spülen, eine fünfte Wanne zum Chromatisieren mit schwacher Chromsäure, eine sechste Wanne zum Spülen mit vollentsalztem Wasser und eine siebente Wanne zum Reinspülen vorgesehen sein.In practice, e.g. a first tubs for pickling-degreasing by means of a weakly alkaline solution, a second tub for rinsing with water, a third trough for pickling (neutralizing) for weak, e.g. 10% sulfuric acid, a fourth tub for rinsing, a fifth tub for chromating with weak chromic acid, a sixth tub for Rinse with deionized water and a seventh tub for rinsing be provided.

Im Bereich der Decke 2 des Gebäudes, in dem die erfindungsgemäße Anlage untergebracht ist, ist eine Transporteinrichtung 3 vorgesehen, welche Schienen 4 umfaßt, auf welchen motorisch taktweise angetriebene Träger 5 laufen, an welchen ebenfalls nur schematisch angedeutete Halteeinrichtungen 6 für die daran hängenden, zu behandelnden Gegenstände 7 angebracht sind.In the area of the ceiling 2 of the building in which the system according to the invention is housed, a transport device 3 is provided, which Rails 4, on which motor-driven carrier 5 run on which also only schematically indicated holding devices 6 attached to the hanging objects to be treated 7 are.

Die Transporteinrichtung 3 transportiert die Halteeinrichtungen 6 in Richtung des Pfeils 8 in Fig. 1 taktweise derart, daß die Halteeinrichtungen 6 jeweils über einer Wanne 1 für die Dauer einer nachfolgend noch zu beschreibenden Sprühbehandlung verbleiben, um dann jeweils wieder einen weiteren Transportschritt, z.B. von der Wanne 1a zur Wanne 1b, weitertransportiert zu werden.The transport device 3 transports the holding devices 6 in the direction of the arrow 8 in FIG. 1 in cycles such that the holding devices 6 each over a tub 1 for the duration of a to be described below Spray treatment remain, then one at a time further transport step, e.g. from tub 1a to tub 1b, transported further to become.

An Haltestangen 18 sind ziehharmonikaartig zusammenfaltbare Trennelemente 15 angeordnet, welche beispielsweise durch eine Folie gebildet sind, welcher unter Ausbildung von Faltlinien umgebogen und mit einer Schweißnaht versehen ist, wobei es zudem vorgesehen sein kann, daß die Schweißnähte eine Art Hohlsaum ausbilden, in welchen jeweils eine Metallstange eingeschoben ist, so daß aufgrund des Gewichts dieser Stangen das selbsttätige Zusammenfalten beim Absenken der Haltestangen 19 begünstigt wird. Überdies kann vorgesehen sein, daß die einzelnen Lamellen eine Bohrung aufweisen, durch die eine Art Führungsfaden geführt ist. On support rods 18 are accordion foldable separating elements 15 arranged, which are formed for example by a film, which bent to form fold lines and with a Weld seam is provided, and it can also be provided that the Weld seams form a kind of hemstitch, in each of which a metal rod is inserted so that due to the weight of these rods the automatic folding when lowering the support rods 19 favors becomes. In addition, it can be provided that the individual slats have a hole through which a kind of guide thread is guided.

An den Trennelementen 15 sind über die gesamte Höhe verteilt Ringleitungen 10 mit Sprühdüsen 11 angeordnet, welche beispielsweise durch den Folienüberzug festgelegt sind. Hierdurch ist es möglich, die zu behandelnden Gegenstände ohne Sprühschatten über ihre gesamte Länge zu besprühen.Ring lines are distributed over the entire height of the separating elements 15 10 arranged with spray nozzles 11 which, for example, by the Foil cover are set. This makes it possible to treat those Spray objects over their entire length without spray shadows.

Bei der in Fig. 4 dargestellten Ausführungsform sind die Trenneinrichtungen 15 als Folien ausgebildet, wobei wiederum Haltestangen 18 zur Erzielung einer definierten Faltung vorgesehen sind. Auch hier sind an der Trenneinrichtung 15 Ringleitungen 10 mit Sprühdüsen 11 über die Höhe verteilt angeordnet.In the embodiment shown in Fig. 4, the separation devices 15 formed as foils, again holding rods 18 to achieve a defined folding are provided. Here too are at the Separating device 15 ring lines 10 with spray nozzles 11 over the height distributed.

Die vorstehend beschriebene erfindungsgemäße Anlage arbeitet also so, daß in der Ausgangsposition die Haltestangen 18 mit den Leitungen 10 abgesenkt sind bis in den Bereich unterhalb des unteren Endes 25 der Halteeinrichtungen 6. Dementsprechend können die Halteeinrichtungen 6 mit den zu behandelnden Gegenständen 7 in den Bereich der Wannen 1 taktweise von einer Wanne 1a zu einer Wanne 1b bzw. 1c bzw. 1d verfahren werden. Nachdem die Transporteinrichtung 3 nach einer derartigen taktweisen Transportbewegung zum Stillstand gekommen ist, werden die Haltestangen 18 mit dem Träger 21 nach oben gefahren, so daß die Trennelemente 15 zwischen deren Unterkante 16 und der nach oben bewegten, in Fig. 1 in ihrer oberen Endlage dargestellten Haltestange 18 aufgefaltet werden. Damit ist trotz der räumlichen Nähe zweiter benachbarter Auffangwannen 1 der Raum oberhalb derselben hermetisch von der jeweils benachbarten Wanne getrennt. The system according to the invention described above thus works that in the starting position, the support rods 18 lowered with the lines 10 are in the area below the lower end 25 of the holding devices 6. Accordingly, the holding devices 6 with the objects 7 to be treated in the area of the tubs 1 in cycles move from a tub 1a to a tub 1b or 1c or 1d become. After the transport device 3 after such a cycle The transport movement has come to a standstill, the handrails 18 moved upwards with the carrier 21, so that the separating elements 15 between the lower edge 16 and the moved upward, in Fig. 1 in its upper end position shown support rod 18 are unfolded. This is despite the spatial proximity of two neighboring sumps 1 the space above it hermetically from the neighboring one Tub separated.

Es können nun die Leitungen 10 mit den Sprühdüsen 9 aktiviert werden, so daß die Gegenstände 7 aus unterschiedlichen Winkeln, und damit sehr gleichmäßig, besprüht werden. Zur Erzielung einer noch stärkeren Vergleichmäßigung können die Düsen auf- und abbewegt werden. Danach werden die Haltestangen 18 wieder abgesenkt, wobei die Trennelemente 15 zusammengefaltet werden.The lines 10 can now be activated with the spray nozzles 9, so that the objects 7 from different angles, and thus very much be sprayed evenly. To achieve an even greater leveling the nozzles can be moved up and down. After that the support rods 18 are lowered again, the separating elements 15 be folded together.

Die Transporteinrichtung 3 kann nun einen weiteren taktweisen Transportschritt veranlassen.The transport device 3 can now perform a further cyclical transport step cause.

Dementsprechend ist es aufgrund der erfindungsgemäßen Lösung möglich, auf engstem Raum eine sehr intensive Behandlung vorzunehmen.Accordingly, the solution according to the invention makes it possible to to perform a very intensive treatment in a confined space.
