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 plant for spray pretreatment to be coated in a downstream coating plant Objects, each with a plurality of such items and holding device arranged on a transport device is and cyclically successively a plurality of the transport device of spray pre-treatment devices with drip pans for the Treatment medium is supplied, the drip pans immediately are arranged adjacent to each other, and wherein in the area of Edges between two trays one with release of the transport path is provided from this movable separating device.

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 separating elements in the form of weak liquors and against Acids resistant curtains or blinds provided. These dividers are with their lower edge with the area between two drip pans or with the edge region of the outermost drip pan connected. Winding shafts are with the opposite end portion connected to the separating elements and in turn in the area of the ceiling over Cables stored. The ends of the winding shafts are each on a horizontal Carrier rotatably arranged, with each two horizontal Carrier are guided on a holding device on both sides 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.Furthermore, spray nozzles are arranged in the area of each tub, which at a rectangular, annularly closed line are formed, wherein each line has a central inflow. The ring lines are about provided outside of the respective tub bearings on holding devices by means of motor drives in the vertical direction, so that the objects to be treated are viewed in the vertical direction from sprinkled on all sides and spray shadows are avoided in this way.

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 plants have become extremely expensive in practice proven, because they allow a very compact, space-saving design and also an economical pretreatment 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 foil-like separating elements can at some applications have the disadvantage that during winding the two sides of the film come into contact with each other, so that it for example in the separation of acidic versus basic baths for reactions, ie e.g. salt formation, comes, so that form deposits and 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 form the separators accordion-like collapsible, in this folding the individual accordion-like Separator sections each only to lie against each other come that a contact between separating elements, the different Baths are avoided is avoided. Independent of this Design of the separating elements is according to this prior art but also still provided that spray nozzles arranged separately and are driven.

Aus DE 19 01 121 A ist es bekannt, daß eine Sprühdüsen-Anordnung in die Trennelemente integriert ist und zusammen mit den Trennelementen anhebbar und absenkbar ist. From DE 19 01 121 A it is known that a spray nozzle arrangement in the separating elements is integrated and together with the separating elements can be raised and lowered.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Anlage der in Betracht stehenden Art noch kompakter, einfacher und kostengünstiger aufzubauen.On this basis, the invention is based on the object, a plant the type in question even more compact, simpler and cheaper build.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in die Trennelemente eine Sprühdüsenanordnung integriert ist, die zusammen mit den Trennelementen anhebbar und absenkbar ist, wobei die Sprühdüsen auf beiden Seiten der Trennelemente angeordnet sind, wenn die Trennelemente nicht randseitig, sondern zwischen zwei benachbarten Wannen angeordnet sind.This object is achieved in that in the separating elements a spray nozzle assembly is integrated, which together with the Separating elements can be raised and lowered, the spray nozzles on Both sides of the separating elements are arranged when the separating elements not edge-sided, but arranged between two adjacent tubs are.

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 on the height and Width of the dividers are largely evenly distributed to this way to ensure the most uniform possible spraying. The spray nozzles can during the spraying - as conventionally the case is still moving up and down with a small amplitude become.

Bei einer bevorzugten Ausführungsform sind die Trennelemente aus einer Mehrzahl von horizontal verlaufenden, ziehharmonikaartig über Gelenke verbundenen Lamellen gebildet.In a preferred embodiment, the separating elements are made of a Plurality of horizontally extending, accordion-like over joints formed slats.

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 may be coated with a coating, e.g. be provided with a plastic film, which on the one hand the lines for the spray nozzles and.die spray nozzles and at the same time also the articulated connection between produces 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.At the individual slats can laterally alternately on the one and the other side rods are attached, which ensure that when retracting the separator 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 plant shown in the drawing comprises a Plurality of drip pans 1, wherein in the drawing of simplicity half only four tubs 1a to 1d are shown, although for most In practical applications, several such trays, 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 slightly alkaline solution, a second bath for rinsing with water, a third tray for decanting (neutralizing) for weak, e.g. 10% sulfuric acid, a fourth sink to rinse, a fifth pan to chromate with weak chromic acid, a sixth pan to Rinse with demineralized water and a seventh bath 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 plant according to the invention is housed, a transport device 3 is provided, which Rails 4 includes, on which motorized cyclically driven carrier. 5 run, on which also only schematically indicated holding devices 6 attached to the hanging, to be treated objects 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 intermittently such that the holding devices. 6 each above a tub 1 for the duration of a later to be described Spray treatment remain, then each one again further transport step, e.g. from the tub 1a to the tub 1b, further transported 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 concertina foldable separators 15 arranged, which are formed for example by a film, which bent under formation of fold lines and with a Weld is provided, it may also be provided that the Welds 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. Moreover, it can be provided that the individual slats have a bore 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.At the dividing elements 15 are distributed over the entire height ring lines 10 arranged with spray nozzles 11, which for example by the Foil coating are set. This makes it possible to treat the Sprinkle objects without spray shadow over their entire length.

Bei der in Fig. 4 dargestellten Ausführungsform sind die Trennelemente 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 separating elements 15 formed as films, again holding rods 18 to achieve a defined folding are provided. Also here are at the Separator 15 ring lines 10 with spray nozzles 11 over the height arranged 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 plant according to the invention described above thus works in this way, that lowered in the initial position, the support rods 18 with the lines 10 are up to the area below the lower end 25 of the holding devices 6. Accordingly, the holding devices 6 with the objects to be treated 7 in the area of the wells 1 cyclically from a tub 1a to a tub 1b or 1c and 1d process become. After the transport device 3 after such a clockwise Transport movement has come to a standstill, the handrails 18 with the carrier 21 moved upwards, so that the separating elements 15 between the lower edge 16 and the upwardly moved, in Fig. 1 shown in its upper end position holding rod 18 are unfolded. This is despite the proximity of second adjacent drip pans 1, the space above it hermetically from the adjacent one Pan isolated.

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.It can now be activated with the spray nozzles 9, the lines 10 so that the objects 7 from different angles, and therefore very evenly, be sprayed. To achieve even greater equalization The nozzles can be moved up and down. After that the support rods 18 are lowered again, wherein the separating elements 15th folded up.

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

Dementsprechend ist es aufgrund der erfindungsgemäßen Lösung möglich, auf engstem Raum eine sehr intensive Behandlung vorzunehmen.Accordingly, it is possible due to the solution according to the invention, to carry out a very intensive treatment in the narrowest of spaces.
