Description

Die Erfindung betrifft eine Vorrichtung zum Beschichten von mindestens einer Fläche von vorzugsweise tafelförmigen Werkstücken, die mit Fördereinrichtungen an mindestens einem am freien Ende eines Schwenkarmes gehaltenen sowie über die zu beschichtenden Werkstücke hin- und herbewegbaren Spritzgerät vorbeiführbar sind.The invention relates to a device for coating at least one surface of preferably table-shaped workpieces, which can be moved past conveyor devices by at least one spraying device held at the free end of a swivel arm and movable over the workpieces to be coated.

Bei der Beschichtung von Werkstücken mit über dieselben auf einem kreisbogenförmigen Weg hin- und herbewegten Spritzgeräten bereitet der gleichmäßige Auftrag der Beschichtung Schwierigkeiten, da die Geschwindigkeit, mit der die Spritzgeräte über die Werkstücke streichen, unter anderem durch die Richtungsänderung der Bewegung am Ende des Schwenkweges nicht konstant ist. Diesen Problemen kann entweder mit speziellen Getrieben für den Antrieb des Schwenkarmes oder einer wegabhängigen Mengenänderung des den Spritzgeräten zugeführten Beschichtungsmittels begegnet werden, was einen erheblichen technischen Aufwand erfordert.When coating workpieces with spraying devices which are moved back and forth over them in an arc-shaped way the uniform application of the coating difficulties, since the speed at which the spraying devices sweep over the workpieces is not constant, among other things due to the change in direction of the movement at the end of the swivel path. These problems can either be countered with special gears for driving the swivel arm or a path-dependent change in the quantity of the coating agent supplied to the spraying devices, which requires considerable technical effort.

Aufgabe der Erfindung ist es nun, eine Vorrichtung der eingangs beschriebenen Art so weiterzubilden, daß trotz erheblicher Verringerung der Herstellungskosten Werkstücke unterschiedlicher Abmessung über die gesamte Breite gleichmäßig beschichtet werden.The object of the invention is now to develop a device of the type described in the introduction such that workpieces of different dimensions are coated uniformly over the entire width despite a considerable reduction in the production costs.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das schwenkbar gelagerte Ende des Schwenkarmes, an dem ein an einem Festpunktgelenk gehaltener Lenker angreift, in einer Geradführung verschiebbar ist. Dabei kann die den Schwenkarm bewegende einen Kurbeltrieb oder eine fluidbetätige Kolben-Zylinder-Anordnung umfassende Antriebseinrichtung am Schwenkarm oder am Lenker angreifen.This object is achieved in that the pivotally mounted end of the Swivel arm, on which a handlebar held at a fixed point joint engages, is displaceable in a straight guide. The drive device that moves the swivel arm can engage a crank mechanism or a fluid-actuated piston-cylinder arrangement on the swivel arm or on the handlebar.

Zur Anpassung des Abstandes des Spritzgerätes an die Stärke der Werkstücke hat es sich bewährt, den Schwenkarm in bezug auf die Fördereinrichtung höhenverstellbar anzuordnen.In order to adapt the distance of the spraying device to the thickness of the workpieces, it has proven useful to arrange the swivel arm so that it can be adjusted in height with respect to the conveying device.

Um die Reinigung der sich quer zur Förderrichtung erstreckenden Stützen der Fördereinrichtung, mit der die Werkstücke aus der erfindungsgemäßen Beschichtungsvorrichtung ausgetragen werden, zu erleichtern, sind bei einer zweckmäßigen Weiterbildung der Neuerung die Auflageflächen dieser Stützen als auswechselbare Winkelschienen ausgebildet, wobei auf dem Scheitelpunkt dieser Schienen die Werkstücke vorzugsweise mit den Rändern aufliegen.In order to facilitate the cleaning of the supports of the conveying device, which extend transversely to the conveying direction and with which the workpieces are discharged from the coating device according to the invention, the support surfaces of these supports are interchangeable angle rails in an expedient development of the innovation formed, the workpieces preferably resting with the edges on the apex of these rails.

Ein Ausführungsbeispiel der Erfindung wird noch an Hand der Zeichnung beschrieben, in der in schematischer Draufsicht insbesondere die Ausgestaltung des Schwenkarmes einer Vorrichtung zum Beschichten von Werkstücken gezeigt ist.An embodiment of the invention will be described with reference to the drawing, in which a schematic top view shows in particular the configuration of the swivel arm of a device for coating workpieces.

Das Spritzgerät 1, mit dem die Oberfläche eines nicht dargestellten Werkstückes, z. B. einer Blechtafel, die mit einem Zu- und Abförderer 2 bzw. 3 kontinuierlich in Richtung X transportiert wird, z. B. eine Rostschutzfarbe aufgebracht wird, ist am freien Ende eines Schwenkarmes 4 befestigt. Das andere Ende des Schwenkarmes 4 ist in einer Geradführung 5 verschiebbar angeordnet. Am Schwenkarm 4 greift noch ein Lenker 6 an, der an einem Festpunktgelenk 7 gehalten ist, dessen Drehpunkt auf der Achslinie 11 der Geradführung 5 liegt. Auf den Anlenkpunkt 8 des Lenkers 6 am Schwenkarm 4 wirkt noch eine nicht dargestellte hydraulisch oder pneumatisch betätigbare Kolben-Zylinder-Anordnung ein, mit der der Schwenkarm 4 und damit das Spritzgerät 1 über das zu beschichtende Werkstück hin- und herbewegt wird.The sprayer 1, with which the surface of a workpiece, not shown, for. B. a metal sheet that is continuously transported in a direction X with a feed and discharge conveyor 2 or 3, for. B. an anti-rust paint is attached to the free end of a swivel arm 4. The other end of the swivel arm 4 is slidably arranged in a straight guide 5. A link 6, which is held at a fixed point joint 7, also acts on the swivel arm 4 is whose fulcrum lies on the axis line 11 of the straight guide 5. On the articulation point 8 of the handlebar 6 on the swivel arm 4 there is also a hydraulically or pneumatically actuable piston-cylinder arrangement, not shown, with which the swivel arm 4 and thus the spraying device 1 is moved back and forth over the workpiece to be coated.

Die Auflagen für die Werkstücke an den sich quer zur Transportrichtung X erstreckenden Stützen 9 des Abförderers 3 sind als auswechselbare Winkelschienen 10 ausgebildet, wobei auf den Scheitelpunkten dieser Schienen 10 die Werkstücke aufliegen.The supports for the workpieces on the supports 9 of the discharge conveyor 3 extending transversely to the transport direction X are designed as interchangeable angle rails 10, the workpieces resting on the vertices of these rails 10.

Falls die tafelförmigen Werkstücke von beiden Seiten beschichtet werden sollen, ist eine weitere Schwenkarmanordnung der vorstehend beschriebenen Ausbildung unterhalb des Zu- und Abförderers 2 bzw. 3 vorgesehen, und so angeordnet, daß das Spritzgerät 1 im Bereich zwischen dem Zu- und Abförderer 2 bzw. 3 auf das Werkstück einwirkt. Dabei können sowohl der obere 4 als auch der untere Schwenkarm mit der gleichen Antriebseinrichtung bewegt werden.If the tabular workpieces are to be coated from both sides, a further swivel arm arrangement of the design described above is provided below the feed and discharge conveyor 2 or 3, and is arranged in such a way that the spraying device 1 acts on the workpiece in the area between the feed and discharge conveyor 2 or 3. Both the upper 4 and the lower swivel arm can be moved with the same drive device.
