Abstract

A spray booth provided with a horizontally oriented nozzle for the surface-coating (e.g. coloring) of suspended workpieces passing by on a transporter is provided with an upright stationary screen intercepting excess coating material. The screen is spaced from the floor of the booth so as to enable the continuous circulation of two wipers therearound, one of them ascending behind the screen while the other descends on its front surface facing the nozzle. The screen is overlain by a sprinkler depositing solvent on its front surface to keep the intercepted coating material in a liquid state.

Description

Die Erfindung betrifft eine Vorrichtung zur Spritzbehandlung insbesondere zur Spritzlackierung von Gegenständen mit einer sich quer zur Spritzrichtung erstreckenden Niederschlagsfläche für das an den Gegenständen vorbeitretende Spritzmedium, mit mindestens einem Abstreifer zum Entfernen des Niederschlages von der Niederschlagsfläche und einer unterhalb der Niederschlagsfläche angeordneten Auffangwanne.The invention relates to a device for spray treatment, in particular for spray painting objects with a precipitation surface extending transversely to the spray direction for the spray medium passing past the objects, with at least one scraper for removing the precipitation from the precipitation surface and a collecting trough arranged below the precipitation surface.

Bei bekannten Vorrichtungen der gattungsgemäßen Art (DE-A-2 823 958) wird die Niederschlagsfläche für das an den zu behandelnden Gegenständen vorbeitretende Spritzmedium, das sogenannte Overspray bewegt, während der Abstreifer stationär angeordnet ist. Bei einer solchen bewegten Niederschlagsfläche kann es sich bspw. um eine rotierende Scheibe, oder um ein laufendes Band handeln, welche jeweils an einem oder an mehreren Abstreifern entlanggeführt werden.In known devices of the generic type (DE-A-2 823 958), the precipitation surface for the spray medium passing by the objects to be treated, the so-called overspray, is moved while the scraper is arranged in a stationary manner. Such a moving precipitation surface can be, for example, a rotating disk or a moving belt, each of which is guided along one or more scrapers.

Diese herkömmlichen Vorrichtungen zur Rückgewinnung des bei der Oberflächenbeschichtung von Gegenständen anfallenden Oversprays besitzen, wird einmal das laufende Band betrachtet, den Nachteil, daß ausreichend große Andruckkräfte zwischen den Abstreifern und der Niederschlagsfläche des flexiblen Bandes nicht immer sicher erzielt werden können. Das hat zur Folge, daß die Niederschlagsfläche, insbesondere bei etwas älteren und abgenutzten Abstreifern, nur ungenügend vom Overspray befreit wird.These conventional devices for recovering the overspray accumulated in the surface coating of objects, once the running belt is considered, the disadvantage that sufficiently large pressure forces between the wipers and the precipitation surface of the flexible belt cannot always be reliably achieved. The consequence of this is that the precipitation area, in particular in the case of somewhat older and worn scrapers, is only insufficiently freed from the overspray.

Die rotierende Scheibe besitzt dagegen im Bereiche des Abstreifers eine Stützvorrichtung, die die Achse der Scheibe vor Biegung und vor Bruch schützen soll. Die Biegebeanspruchung der Achse wird dadurch gemindert, daß die Scheibe vom Abstreifer gegen die Stützvorrichtung gedrückt wird. Das bedeutet aber, daß zwischen der Scheibe und der Stützvorrichtung der Scheibe eine erhebliche Reibung auftritt, so daß der Antriebsmotor der Scheibe eine verhältnismäßig große Leistung erbringen muß.The rotating disk, on the other hand, has a support device in the area of the scraper, which is intended to protect the axis of the disk from bending and breakage. The bending stress on the axle is reduced by the fact that the washer is pressed against the support device by the scraper. However, this means that considerable friction occurs between the disc and the support device of the disc, so that the drive motor of the disc has to provide a relatively large output.

Ein weiterer Grund, der einen großen und teueren Motor sowohl für den Antrieb der Scheibe als auch für den Antrieb des Bandes notwendig macht, sind die großen Massen, die bewegt werden müssen.Another reason that makes a large and expensive motor necessary for both the drive of the disc and the drive of the belt is the large masses that have to be moved.

Oft handelt es sich bei dem bewegten Band um ein Gliederband, welches zwischen jedem einzelnen Glied Fugen aufweist, die an den Abstreifern vorbeibewegt werden und dabei den Abstreifer mechanisch besonders stark beanspruchen. Diese Beanspruchung führt dazu, daß der Abstreifer schnell verschleißt und unbrauchbar wird.Often, the moving belt is a link belt which has joints between each individual link, which are moved past the wipers and thereby subject the wiper to particularly high mechanical stresses. This stress causes the scraper to wear out quickly and become unusable.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, die genügend große Andruckkräfte zwischen dem Abstreifer und der Niederschlagsfläche zuläßt, trotzdem aber nicht viel Energie zur Überwindung der Reibung und für den Antrieb von bewegten Massen benötigt, und sich durch geringe Störanfälligkeit auszeichnet.The invention has for its object to provide a generic device that allows enough large pressure forces between the wiper and the precipitation surface, but still does not require a lot of energy to overcome the friction and for driving moving masses, and is characterized by low susceptibility to interference.

Diese Aufgabe wird dadurch gelöst, daß die Niederschlagsfläche auf einer stationären Wand ausgebildet und der Abstreifer über die Niederschlagsfläche hinwegbewegbar angeordnet ist. Eine auf einer stationären Wand angeordnete Niederschlagsfläche läßt sich entsprechend stabil aufbauen, so daß diese den nötigen, durch den Abstreifer auf die Niederschlagsfläche aufzubringenden Andruckkräften standhält.This object is achieved in that the precipitation area is formed on a stationary wall and the scraper is arranged to be movable over the precipitation area. A precipitation surface arranged on a stationary wall can be built up in a correspondingly stable manner so that it withstands the necessary pressure forces to be applied to the precipitation surface by the scraper.

Eine besonders zweckmäßige Ausgestaltung dieser Vorrichtung ergibt sich nach einem weiterbildenden Neuerungsmerkmal, wenn entlang zweier paralleler Seitenkanten der stationären Wand über Umlenkrollen laufende endlose Ketten oder dergleichen geführt sind, an denen der Abstreifer in vorzugsweise rechtwinkliger Anordnung zu den Kettensträngen oder dergleichen befestigt ist. Die beiden endlosen Ketten sowie der Abstreifer haben gegenüber den bewegten Teilen der bekannten Vorrichtung zur Rückgewinnung des Oversprays eine sehr kleine Masse, so daß ein billiger Motor mit kleiner Leistung eingesetzt werden kann.A particularly expedient embodiment of this device results from a further innovative feature if endless chains or the like are guided along two parallel side edges of the stationary wall via deflection rollers, to which the stripper is attached in a preferably rectangular arrangement to the chain strands or the like. The two endless chains and the scraper have a very small mass compared to the moving parts of the known device for recovering the overspray, so that a cheap motor with low power can be used.

Von Vorteil ist, daß der Abstreifer in Abwärtsrichtung über die Niederschlagsfläche bewegbar ist, wodurch gewährleistet wird, daß bereits gesäuberte Flächen der Niederschlagsfläche nicht von vom Abstreifer heruntertropfenden Farbresten getroffen werden.It is advantageous that the stripper can be moved in the downward direction over the precipitation surface, which ensures that areas of the precipitation surface that have already been cleaned are not hit by paint residues dripping from the stripper.

Als günstig hat es sich erwiesen, daß der Abstreifer mindestens ein sich über die ganze Breite der Niederschlagsfläche erstreckende flexible Schieberlippe aufweist, so daß die ganze Niederschlagsfläche bei einer Abwärtsbewegung des Abstreifers gereinigt wird.It has proven to be advantageous that the scraper has at least one flexible slide lip which extends over the entire width of the precipitation area, so that the entire precipitation area is cleaned when the scraper moves downward.

Es empfiehlt sich, mindestens zwei Abstreifer an den Ketten oder dergleichen vorzusehen, da dadurch die Abstreifintervalle bedeutend verkleinert werden. Dadurch können größere Mengen des sich im Overspray befindenden Lösungsmittels vor dessen Verdunstung zurückgewonnen werden. Außerdem brauchen die Ketten, die von einem in seiner Umdrehungszahl regelbaren Motor angetrieben werden, nicht so schnell bewegt zu werden wie das bei Verwendung nur eines Abstreifers notwendig ist.It is advisable to provide at least two wipers on the chains or the like, since this significantly reduces the wiping intervals. This allows larger amounts of the solvent in the overspray to be recovered before it evaporates. In addition, the chains, which are driven by a motor whose speed can be regulated, do not have to be moved as quickly as is necessary when using only one scraper.

Besonders bemerkenswert ist, daß entlang der Oberkante der Wand eine Sprühvorrichtung oder dergleichen für Lösungsmittel angeordnet ist, wobei die Sprühdüsen der Sprühvorrichtung auf den oberen Bereich der Niederschlagsfläche ausgerichtet sind. Das aus der Sprühvorrichtung auf die Niederschlagsfläche aufgebrachte Lösungsmittel wirkt hierbei dem durch Verdunstung bewirkten Lösungsmittelverlust des Oversprays entgegen und hält das Overspray flüssig, so daß ein sauberes Abstreifen des Oversprays von der Niederschlagsfläche gewährleistet ist.It is particularly noteworthy that a spray device or the like for solvents is arranged along the upper edge of the wall, the spray nozzles of the spray device being aligned with the upper region of the precipitation surface. The solvent applied to the precipitation surface from the spray device counteracts the solvent loss of the overspray caused by evaporation and keeps the overspray liquid, so that a clean wiping of the overspray from the precipitation surface is ensured.

Ein Ausführungsbeispiel der Neuerung wird anhand der Zeichnung näher erläutert. Es zeigt

  • Fig. 1 die Seitenansicht einer neuerungsgemäßen Vorrichtung zur Spritzbehandlung von Gegenständen,
  • Fig. 2 eine Vorderansicht der neuerungsgemäßen Vorrichtung und
  • Fig. 3 einen zur Vorrichtung nach Fig. 1 und 2 gehörenden Auffangbehälter für das zurückgewonnene Overspray in Vorderansicht.
An embodiment of the innovation is explained in more detail with reference to the drawing. It shows
  • Fig. 1 is a side view of an inventive device for spray treatment of Objects,
  • Fig. 2 is a front view of the device according to the innovation and
  • Fig. 3 is a front container of the device according to FIGS. 1 and 2 for the recovered overspray.

In Fig. 1 ist ein zu beschichtender Gegenstand 1 zu erkennen. Der Gegenstand 1 wird von einem Spritzmedium 2 beaufschlagt. Das Spritzmedium 2 tritt aus einer Spritzvorrichtung 3 aus, welche an einem ortsfesten Stativ 4 auf- und abbewegbar angeordnet ist.An object 1 to be coated can be seen in FIG. 1. The object 1 is acted upon by a spray medium 2. The spray medium 2 emerges from a spray device 3, which is arranged so that it can be moved up and down on a stationary stand 4.

In Spritzrichtung hinter dem beschichteten Gegenstand 1 ist eine mit der Niederschlagsfläche 5 versehene Wand 6 stationär angeordnet (siehe auch Fig. 2). Um Umlenkrollen 7 sind zwei endlose Ketten 8 gelegt. Zwei auf einer Achse liegende Umlenkrollen werden durch einen regelbaren Motor M angetrieben.In the spray direction behind the coated object 1, a wall 6 provided with the precipitation surface 5 is arranged in a stationary manner (see also FIG. 2). Two endless chains 8 are placed around deflection rollers 7. Two deflecting rollers lying on one axis are driven by an adjustable motor M.

Dadurch werden die Ketten 8 in der durch die Pfeile A dargestellte Richtung bewegt.As a result, the chains 8 are moved in the direction shown by the arrows A.

Zwischen den beiden Ketten 8 sind zwei Abstreifer 9 rechtwinklig zu den Ketten 8 angeordnet. Die Abstreifer 9 sind fest mit den Ketten 8 verbunden. Zur Stabilisierung der Bewegungsbahn der Abstreifer 9 ist eine Führung vorgesehen, in die der sich jeweils abwärts bewegende Abstreifer 9 einläuft. Als Führung wird ein mit der Wand 6 verbundenes Profil 9' genutzt.Between the two chains 8, two wipers 9 are arranged at right angles to the chains 8. The wipers 9 are firmly connected to the chains 8. To stabilize the path of movement of the wipers 9, a guide is provided, into which the wipers 9, which move downward, run. A profile 9 'connected to the wall 6 is used as a guide.

An den Abstreifern 9 befindet sich die Schieberlippe 10. Die Schieberlippe 10 dient dazu, das am zu beschichtenden Gegenstand 1 vorbeitretende Spritzmedium 2 von der Niederschlagsfläche 5 zu entfernen. Damit das sogenannte Overspray stets flüssig und mittels der Schieberlippen 10 von der Niederschlagsfläche 5 abstreifbar bleibt, wird durch eine Sprühvorrichtung 11 Lösungsmittel 12 im oberen Teil der Niederschlagsfläche 5 aufgebracht. Das Lösungsmittel läuft an der Niederschlagsfläche 5 entlang, gleicht somit die Lösungsmittelverluste im Overspray aus, und hält das Overspray flüssig.The slide lip 10 is located on the wipers 9. The slide lip 10 serves to remove the spray medium 2 passing the object 1 to be coated from the precipitation surface 5. So that the so-called overspray always remains liquid and can be stripped from the precipitation surface 5 by means of the slide lips 10, solvent 12 is applied in the upper part of the precipitation surface 5 by a spray device 11. The solvent runs along the precipitation surface 5, thus compensating for the solvent losses in the overspray, and keeps the overspray liquid.

Das mittels der Schieberlippe 10 von der Wand 6 entfernte Overspray gelangt in eine Auffangwanne 13. Hier sorgt ein Sprühsystem 14 für eine gute Vermischung der festen Bestandteile des Sprühmediums 2 mit dem Lösungsmittel. Das Sprühsystem 14 ist schwenkbar ausgeführt. Dadurch ist es möglich, daß die Auffangwanne 13, im ausgeschwenkten Zustand des Sprühsystems 14, aus dem sie stützenden und lose halternden Behälter 15 herausgenommen werden kann.The overspray removed from the wall 6 by means of the slide lip 10 reaches a collecting trough 13. Here, a spray system 14 ensures good mixing of the solid components of the spray medium 2 with the solvent. The spray system 14 is designed to be pivotable. This makes it possible for the collecting trough 13, in the swung-out state of the spray system 14, to be removed from the supporting and loosely holding container 15.

Fig. zeigt, wie die mit einer Farbe gefüllte Auffangwanne 13 gegen eine leere Wanne ausgetauscht wird. Es ist ebenso möglich, die Wanne 13 gegen eine mit einer anderen Farbe gefüllte Wanne auszutauschen.Fig. Shows how the collecting tray 13 filled with a color is exchanged for an empty tray. It is also possible to replace the tub 13 with a tub filled with a different color.
