Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Beschichtungsanlage zum Beschichten eines Werkstücks sowie ein Verfahren zum Betreiben der Beschichtungsanlage. Die Beschichtungsanlage ist beispielsweise zum Beschichten von Werkstücken mit Beschichtungspulver, das im Folgen kurz Pulver genannt wird, geeignet.The invention relates to a coating system for coating a workpiece and a method for operating the coating system. The coating system is suitable, for example, for coating workpieces with coating powder, which is hereinafter referred to as powder for short.

Eine Beschichtungsanlage weist meist eine Kabine mit Seitenwänden auf, durch die eine oder mehrer Pulversprühpistolen ins Innere der Kabine ragen. Das zu beschichtende Werkstück wird an einer Förderbahn hängend durch die Kabine transportiert und dabei mit den Pulversprühpistolen mit Pulver besprüht. Anschliessend wird das Werkstück in eine Wärmekammer transportiert. Die Pulverschicht wird in der Wärmekammer so weit erhitzt, so dass sie sich verflüssigt und eine geschlossene Schicht auf dem Werkstück bildet.A coating system usually has a booth with side walls through which one or more powder spray guns protrude into the interior of the booth. The workpiece to be coated is transported hanging on a conveyor track through the cabin and sprayed with powder with the powder spray guns. The workpiece is then transported into a heating chamber. The powder layer is heated in the heating chamber to such an extent that it liquefies and forms a closed layer on the workpiece.

Stand der TechnikState of the art

Aus dem Stand der Technik EP 1 256 386 A2 ist eine Kabine zur Pulverbeschichtung von Werkstücken bekannt. Vor und hinter der Kabine ist jeweils ein Handbeschichterplatz angeordnet, um das Werkstück manuell beschichten zu können. Sollen kleine Losgrössen mit anderen Materialien oder Farbtönen beschichtet werden, sind also zunächst die Kabine und die Einrichtung zur Pulverrückgewinnung einer Reinigung zu unterziehen. Zur Reinigung der Kabine wird zuerst eine zwischen dem Handbeschichterplatz und der Kabine befindliche Schiebetür geschlossen. Dann wird das in der Kabine befindliche Pulver manuell entfernt und anschliessend die Tür wieder geöffnet. Dieser Vorgang ist aufwändig, kostet Zeit und ist auch nicht in jedem Fall praktikabel. Diese Kombination aus Kabine und Handbeschichterplatz ist somit nicht geeignet, um gleichzeitig mit verschiedenen Farbtönen zu arbeiten.From the state of the art EP 1 256 386 A2 a booth for powder coating workpieces is known. A manual coating station is arranged in front of and behind the booth so that the workpiece can be coated manually. If small batches are to be coated with other materials or colors, the booth and the powder recovery device must first be cleaned. To clean the booth, a sliding door located between the manual coating station and the booth is first closed. The powder in the booth is then removed manually and the door is then opened again. This process is complex, time-consuming and is not always practicable. This combination of booth and manual coater station is therefore not suitable for working with different colors at the same time.

Aus der Druckschrift US 5,078,084 ist ein System zum Beschichten von grossen Werkstücken, wie zum Beispiel von Fahrzeugen, mit Pulver bekannt. Dabei soll eine gleichmässige Beschichtung der gesamten Fahrzeugkarosserie gewährleistet sein und ein Grossteil des überschüssigen Pulvers soll gesammelt und zurückgewonnen werden. Das System umfasst einen automatischen Sprühbereich und einen Handbeschichterbereich. Das gesamte überschüssige Pulver, das heisst sowohl das überschüssige Pulver, das vom automatischen Sprühbereich stammt, und das überschüssige Pulver, das vom Handbeschichterbereich abgesaugt wird, wird einem Zyklon zugeführt. Bei diesem System ist es nicht möglich, zwischendurch ein Werkstück manuell im Handbeschichterbereich mit einer anderen Farbe zu beschichten als derjenigen Farbe, die auch im automatischen Sprühbereich verwendet wird.From the pamphlet U.S. 5,078,084 a system for coating large workpieces, such as vehicles, with powder is known.

In the embodiment shown in the figure, two powder storage containers 8.1 and 8.2 are located in the powder center 8. The automatic coating machine 9 is supplied with coating powder from a further powder center 11 via a powder hose 10.

Da nicht das gesamte von den Pulversprühpistolen 6.2, 6.3, 9.2 und 9.3 versprühte Pulver auf das Werkstück 5 trifft und an diesem anhaftet, bleibt ein Teil des Pulvers als sogenanntes Overspray in der Kabine 1 zurück und wird aus dieser mittels einer ersten Kabinenabsaugung und einer zweiten Kabinenabsaugung heraus gesaugt. Die Seitenwand 1.1 der Kabine 1 weist dazu eine Absaugöffnung auf, an die ein Absaugkanal 12 und ein Zyklon-Filter 13 oder kurz Zyklon angeschlossen sind. Die Seitenwand 1.2 der Kabine 1 weist dazu ebenfalls eine Absaugöffnung auf, an die ein weiterer Absaugkanal 17 und ein weiteres Zyklon-Filter 18 angeschlossen sind. In den beiden Zyklon-Filtern 13 und 18 wird nach dem Prinzip der Fliehkraft aus der angesaugten Kabinenluft das Overspray herausgefiltert. Die durch das Zyklon-Filter 13 vorgefilterte Luft wird mittels eines Nachfilters 15, das über eine Rohrleitung 14 mit dem Zyklon-Filter 13 verbunden ist, nochmals gefiltert. Anders als im Zyklon-Filter 13 wird im Nachfilter 15 des Öfteren auf verlust gefahren. Das heisst, das im Nachfilter 15 herausgefilterte Pulver wird dem Beschichtungsprozess nicht mehr zugeführt, sondern entsorgt. Dies muss aber nicht zwingend so gehandhabt werden. Die durch das weitere Zyklon-Filter 18 vorgefilterte Luft wird mittels eines weiteren Nachfilters 20 nochmale gefiltert. Das weitere Nachfilter 20 ist dazu über eine Rohrleitung 19 mit dem weiteren Zyklon-Filter 18 verbunden.Since not all of the powder sprayed by the powder spray guns 6.2, 6.3, 9.2 and 9.3 hits the workpiece 5 and adheres to it, part of the powder remains in the booth 1 as so-called overspray and is extracted from it by means of a first booth suction system and a second Booth exhaust sucked out. The side wall 1.1 of the cabin 1 has a suction opening to which a suction channel 12 and a cyclone filter 13 or cyclone for short are connected. The side wall 1.2 of the cabin 1 also has a suction opening to which a further suction channel 17 and a further cyclone filter 18 are connected. In the two cyclone filters 13 and 18, the overspray is filtered out of the sucked in cabin air according to the principle of centrifugal force. The air pre-filtered by the cyclone filter 13 is filtered again by means of a post-filter 15 which is connected to the cyclone filter 13 via a pipe 14. In contrast to the cyclone filter 13, the secondary filter 15 is often lost. This means that the powder filtered out in the secondary filter 15 is no longer fed to the coating process, but disposed of. However, this does not necessarily have to be handled in this way. The air pre-filtered by the further cyclone filter 18 is filtered again by means of a further post-filter 20. For this purpose, the further secondary filter 20 is connected to the further cyclone filter 18 via a pipe 19.

Bezogen auf die Transportrichtung 4.1 des Werkstücks befindet sich vor der Kabine 1 der erste Handbeschichterstand 2. Dieser ist für das Personal über eine Treppe 2.1 erreichbar und weist eine Seitenwand 2.2 auf, in die eine Absaugöffnung integriert ist. Fällt während der manuellen Beschichtung im Handbeschichterstand 2 Overspray an, wird dieses über die Absaugöffnung und einen Absaugkanal 21 in das Nachfilter 20 gesaugt. Dadurch wird erreicht, dass vom Handbeschichterstand 2 kein Overspray ins Innere 1.7 der Kabine 1 gelangt.In relation to the transport direction 4.1 of the workpiece, the first manual coater stand 2 is located in front of the booth 1. This can be reached by the staff via a staircase 2.1 and has a side wall 2.2 into which a suction opening is integrated. If overspray occurs during manual coating in the manual coating station 2, this is sucked into the post-filter 20 via the suction opening and a suction channel 21. This ensures that from the manual coater stand 2 no overspray reaches the interior 1.7 of the booth 1.

Bezogen auf die Transportrichtung 4.1 des Werkstücks befindet sich hinter der Kabine 1 der zweite Handbeschichterstand 3. Dieser ist für das Personal über eine Treppe 3.3 erreichbar und weist eine erste Seitenwand 3.1 und eine zweite Seitenwand 3.2 auf. Die beiden Seitenwände 3.1 und 3.2 können, anders als in der Figur gezeigt, auch gleich oder spiegelbildlich geformt sein. In die erste Seitenwand 3.1 ist im Bodenbereich eine horizontal verlaufende Absaugöffnung integriert. In die zweite Seitenwand 3.2 ist eine vertikal verlaufende Absaugöffnung mit einem vertikalen Absaugkanal 22 integriert, die mit einem unter dem Boden des Handbeschichterstands 3 verlaufenden Absaugkanal 23 verbunden ist. Der Absaugkanal 23 wiederum mündet in einen Absaugkanal 16, der zum Nachfilter 15 führt. Fällt während der manuellen Beschichtung im Handbeschiehtarstand 3 Overspray an, wird dieses über die beiden Absaugöffnungen, den Absaugkanal 22, den Absaugkanal 23 und den Absaugkanal 16 in den Nachfilter 20 gesaugt. Dadurch wird erreicht, dass vom Handbeschichterstand 3 kein Overspray ins Innere der Kabine 1 gelangt.In relation to the transport direction 4.1 of the workpiece, the second manual coater stand 3 is located behind the booth 1. This can be reached by the staff via a staircase 3.3 and has a first side wall 3.1 and a second side wall 3.2. The two side walls 3.1 and 3.2 can, in contrast to what is shown in the figure, also be shaped identically or as a mirror image. A horizontally running suction opening is integrated into the first side wall 3.1 in the bottom area. A vertically running suction opening with a vertical suction channel 22 is integrated into the second side wall 3.2, which is connected to a suction channel 23 running under the floor of the manual coating stand 3. The suction channel 23 in turn opens into a suction channel 16 which leads to the post-filter 15. If overspray occurs in the manual coating station 3 during manual coating, it is sucked into the post-filter 20 via the two suction openings, the suction channel 22, the suction channel 23 and the suction channel 16. This ensures that no overspray reaches the interior of the booth 1 from the manual coating station 3.

Figur 2 zeigt die erfindungsgemässe Beschichtungsanlage in der Seitenansicht im Schnitt entlang der Schnittkante A-A. Figure 2 shows the coating system according to the invention in a side view in section along the cutting edge AA.

Die Absaugöffnungen in der Kabine 1 und in den Handbeschichterständen 2 und 3 können beispielsweise als Schlitze oder Löcher ausgebildet sein. In Figur 2 sind die Absaugoffnungen 34 im Handbeschichterstand 3 als Löcher ausgebildet.The suction openings in the booth 1 and in the manual coating stands 2 and 3 can be designed as slots or holes, for example. In Figure 2 the suction openings 34 in the manual coating station 3 are designed as holes.

Die beiden Handbeschichterstande 2 und 3 können jeweils mit einer Tür 27 beziehungsweise 26 ausgestattet sein, um die Handbeschichterstände 2 und 3 vom Kabineninneren zu trennen. Dadurch kann erreicht werden, dass von den Handbeschichterständen 2 und 3 kein Overspray ins Innere der Kabine 1 gelangt.The two manual coating stations 2 and 3 can each be equipped with a door 27 and 26, respectively, in order to separate the manual coating stations 2 and 3 from the interior of the booth. This can ensure that no overspray from the manual coating stands 2 and 3 gets into the interior of the booth 1.

Bevor das Werkstück 5 vom Handbeschichterstand 3 aus beschichtet wird, werden mittels einer Umschaltsteuerung 25 zwei Stellmotore 33 angesteuert, um über diese zwei Klappen 30 und 31 zu betätigen. Indem die Klappe 30 geschlossen wird, wird die Kabinenabsaugung abgeschaltet und indem die Klappe 31 geöffnet wird, wird die Handbeschichterabsaugung aktiviert. Die Umschaltsteuerung 25, die Stellmotoren 33 und die beiden Klappen 30 und 31 werden auch als Umschaltmittel bezeichnet. Durch das Schliessen beziehungsweise Öffnen der Klappen 30 und 31 lässt sich die Wahrscheinlichkeit, dass Overspray während des manuellen Beschichtens vom Handbeschichterstand 3 ins Innere der Kabine 1 gelangt, nochmals verringern.Before the workpiece 5 is coated from the manual coating station 3, two servomotors 33 are activated by means of a switchover control 25 in order to operate two flaps 30 and 31 via these. By closing the flap 30, the booth suction is switched off and by opening the flap 31, the manual coater suction is activated. The switchover control 25, the servomotors 33 and the two flaps 30 and 31 are also referred to as switchover means. By closing or opening the flaps 30 and 31, the probability of overspray getting from the manual coating station 3 into the interior of the booth 1 during manual coating can be further reduced.

Sinngemäss das Gleiche gilt für den Betrieb des Handbeschichterstands 2. Bevor das Werkstück 5 vom Handbeschichterstand 2 aus beschichtet wird, werden mittels einer Umscbaltsteuerung 24 zwei Stellmotore 32 angesteuert, um über diese zwei Klappen 28 und 29 zu betätigen. Indem die Klappe 29 geschlossen wird, wird die Kabinenabsaugung abgeschaltet und indem die Klappe 28 geöffnet wird, wird die Handbeschichterabsaugung aktiviert. Auf diese Weise lässt sich die Wahrscheinlichkeit, dass Overspray während des manuellen Beschichtens vom Handbeschichterstand 2 ins Innere 1.7 der Kabine 1 gelangt, weiter verringern. Dies ist insbesondere dann von Vorteil, wenn mit verschiedenen Farbtönen gearbeitet wird.The same applies mutatis mutandis to the operation of the manual coating station 2. Before the workpiece 5 is coated from the manual coating station 2, two servomotors 32 are controlled by means of a switching control 24 in order to operate two flaps 28 and 29 via these. By closing the flap 29, the booth suction is switched off and by opening the flap 28, the manual coater suction is activated. In this way, the probability of overspray getting from the manual coating station 2 into the interior 1.7 of the booth 1 during manual coating can be further reduced. This is particularly advantageous when working with different colors.

Die Pfeile in der Figur kennzeichnen die Strömungsrichtung der Luft, die durch die Absaugöffnungen in den Seitenwänden 3.1 und 3.2 abgesaugt wird.The arrows in the figure indicate the direction of flow of the air that is sucked out through the suction openings in the side walls 3.1 and 3.2.

Die beiden Handbeschichterstände 2 und 3 können jeweils mit einem Dach 35 und die Kabine mit einem Dach 36 ausgestattet sein.The two manual coating stations 2 and 3 can each be equipped with a roof 35 and the cabin with a roof 36.

Der Handbeschichterstand 2 kann ebenso wie der Handbeschichterstand 3 mit einer horizontalen und/oder einer vertikalen Absaugöffnung ausgestattet sein.The manual coating stand 2, like the manual coating stand 3, can be equipped with a horizontal and / or a vertical suction opening.

Die Beschichtungsanlage kann, anders als in der Figur dargestellt, auch mit nur einem Handbeschichterstand aus gestattet sein. Die Transportrichtung des Werkstücks 5 kann auch in die entgegen gesetzte Richtung zeigen.In contrast to what is shown in the figure, the coating system can also be equipped with only one manual coating station. The transport direction of the workpiece 5 can also point in the opposite direction.

Vorteilhafter Weise kann mit der Beschichtungsanlage im Mehrfarbenbetrieb gearbeitet werden. Es lassen sich auf der Handbeschichterständen 2 und 3 verschiedene, kleinere Werkstückchargen mit Farbtönen beschichten, die vom Hauptfarbton in der Kabine 1 abweichen.The coating system can advantageously be used in multi-color mode. On the manual coating stands 2 and 3, different, smaller batches of workpieces can be coated with color shades that differ from the main color shade in booth 1.

Es ist aber auch möglich die Absaugung für den Handbeschichterstand 2 beziehungsweise die Absaugung für den Handbeschichterstand 3 gemeinsam mit der die Absaugung für die Kabine l zu betreiben. Dies ist insbesondere dann von Vorteil, wenn Werkstücke in der Kabine 1 beschichtet und am Handbeschichterstand 2 vorbeschichtet beziehungsweise am Handbeschichterstand 3 nachbeschichtet werden sollen. So können beispielsweise sowohl die Klappe 30 in der Kabinenabsaugung 12 als auch die Klappe 31 in der Handbeschichterstandabsaugung 16 teilweise geöffnet sein. Die Klappen 30 und 31 können so eingestellt werden, dass 80% der abgesaugten Luftmenge über die Kabinenabsaugung 12 und die restlichen 20% der abgesaugten Luftmenge über die Handbeschichterstandabsaugung 16 abgesaugt werden. Auf diese Weise lässt sich der Pulververlust über den Handbeschichterstand 3 noch weiter reduzieren.However, it is also possible to operate the suction for the manual coating stand 2 or the suction for the manual coating stand 3 together with the suction for the booth 1. This is particularly advantageous when workpieces are to be coated in the booth 1 and precoated at the manual coating stand 2 or recoated at the manual coating stand 3. For example, both the flap 30 in the booth suction 12 and the flap 31 in the manual coater suction 16 can be partially open. The flaps 30 and 31 can be adjusted so that 80% of the extracted air volume is extracted via the booth extraction system 12 and the remaining 20% of the extracted air volume via the manual coater stand extraction system 16. In this way, the powder loss via the manual coating station 3 can be reduced even further.
