Description

Derartige Kabinen sind seit langem bekannt und im Einsatz. Bei solchen Kabinen ist der Kabineninnerraum durch Seitenwände, beidendige Stirnwände, einen Kabinenboden und ein Kabinendach begrenzt, welches durch einen Längsspalt geteilt ist. Durch diesen Längsspalt werden gewöhnlich die Werkstücke mittels einer Transportvorrichtung bewegt. Um dies zu ermöglichen, hat die Kabine mindestens in ihrer stromaufwärts gelegenen Stirnwand eine Durchstrittsöffnung für die Werkstücke. Häufig ist seitlich neben der Kabine ein Handbeschichtungsplatz nahe der stromaufwärts gelegenen Stirnwand vorgesehen. Zu diesem Handbeschichtungsplatz gehört eine Öffnung in der Seitenwand der Kabine. Durch die Öffnung hindurch kann ein Handbeschichter mittels einer Handpistole schwierige oder vorzugrundierende Bereiche eines Werkstücks innerhalb der Kabine und in Transportrichtung der Werkstücke stromaufwärts der automatischen Beschichtung vorbeschichten. Falls erwünscht oder erforderlich, ist ein weiterer Handbeschichtungsplatz ebenfalls seitlich der Kabine in Transportrichtung der Werkstücke stromabwärts der automatischen Beschichtung der Werkstücke vorgesehen. Von diesem weiteren Handbeschichtungsplatz aus kann eine Person unzureichend beschichtete und/oder schwierige Stellen des Werkstückes wiederum in der Kabine von Hand nach Bedarf nachbeschichten.Such cabins have long been known and in use. In such cabins, the cabin interior is through side walls, both end walls, a cabin floor and a Cabin roof limited, which is divided by a longitudinal gap. Through this longitudinal gap the workpieces are usually moved by means of a transport device. To do this enable, the cabin has at least in its upstream end wall Through opening for the workpieces. There is often a manual coating station on the side of the cabin provided near the upstream end wall. To this manual coating station includes an opening in the side wall of the cabin. Through the opening a hand coater can be difficult or pre-primed using a hand gun Areas of a workpiece within the cabin and in the transport direction of the workpieces Precoat upstream of the automatic coating. If desired or another manual coating station is also required on the side of the cabin in the direction of transport of the workpieces downstream of the automatic coating of the workpieces intended. From this additional manual coating station, one person can be insufficient coated and / or difficult parts of the workpiece in turn in the cabin of Hand coat as needed.

Dadurch, daß die Handbeschichtung durch Öffnungen in der Kabine hindurch in deren Innenraum vorgenommen werden muß, ist der Freiraum beim Handhaben der Handpistolen eingeschränkt.The fact that the hand coating through openings in the cabin in the interior must be made, the freedom in handling the handguns is limited.

Durch die relativ großen Öffnungen an den Handbeschichtungsplätzen können im Beschichtungsbetrieb Pulverpartikel nach außen entweichen, was umweltschädlich ist und zu Pulververlust führt. Dieser nachteilige Effekt könnte durch eine Erhöhung des Unterdrucks in der Kabine kompensiert werden, was zu einer entsprechend erhöhten Absaugleistung führen und die Strömungsverhältnisse innerhalb der Kabine so verändern würde, daß die Beschichtungsqualität verschlechtert wird. Due to the relatively large openings in the manual coating stations, coating operations can be carried out Powder particles escape to the outside, which is harmful to the environment and leads to powder loss leads. This disadvantageous effect could be caused by an increase in the vacuum in the Cabin can be compensated, which lead to a correspondingly increased suction power and would change the flow conditions within the cabin so that the coating quality is deteriorating.

Ferner sind die Beleuchtungsverhältnisse in der Kabine unzureichend für ein exaktes Arbeiten von Hand. Auf der Höhe der Handbeschichtungsplätze sind daher in der bekannten Kabine Lampen zum Ausleuchten der Werkstücke an den jeweiligen Handbeschichtungsorten vorgesehen, und zwar in der Seitenwand neben den Öffnungen für die Handbeschichtungsplätze, so daß die Werkstücke frontal beleuchtet werden. Diese Lampen werden im Betrieb sehr schnell durch abgelagertes Überschußpulver verschmutzt.Furthermore, the lighting conditions in the cabin are insufficient for precise work by hand. At the height of the manual coating stations are therefore in the known cabin Lamps are provided to illuminate the workpieces at the respective hand coating locations, namely in the side wall next to the openings for the manual coating stations, see above that the workpieces are illuminated from the front. These lamps become very quick in operation soiled by deposited excess powder.

Der Erfindung liegt die Aufgabe zugrunde, eine Kabine der eingangs genannten Art so auszubilden, daß das Entweichen von Pulverpartikeln in die Umgebung der Kabine vermindert und trotzdem eine ungehinderte Handbeschichtung hoher Qualität wirtschaftlich, d.h. insbesondere ohne erhöhte Absaugleistung, erzielbar ist.The invention has for its object to design a cabin of the type mentioned above, that the escape of powder particles in the vicinity of the cabin is reduced and nevertheless an unimpeded hand coating of high quality economically, i.e. in particular can be achieved without increased suction power.

Diese Aufgabe ist durch Patentanspruch 1 gelöst.This object is solved by claim 1.

Bei einer Kabine gemäß der Erfindung sind Öffnungen für die Handbeschichtung in der Seitenwand der Kabine völlig vermieden. Damit ist auch ein Pulveraustritt mit den beschriebenen nachteiligen Folgen über solche Öffnungen unterbunden.In a cabin according to the invention there are openings for hand coating in the side wall completely avoided the cabin. This is also a powder leak with the described prevent adverse consequences of such openings.

An einem erfindungsgemäß in Transportrichtung vor und/oder hinter der Kabine angeordneten Handbeschichtungsplatz werden die Werkstücke anders als beim Stand der Technik auβerhalb der Kabine vor- und/oder nachbeschichtet. Hierdurch steht dem Handbeschichter naturgemäß ein praktisch unbegrenzter Freiraum für ein sorgfältiges Handbeschichten zur Verfügung, der auch nicht bei sehr großen seitlichen Öffnungen für die Handbeschichtung gemäß dem Stand der Technik erreichbar wäre, und dies ohne jeden Zusatzaufwand bei gleichzeitig erhöhter Handbeschichtungsqualität.Arranged in front of and / or behind the cabin in a transport direction according to the invention In contrast to the state of the art, the workpieces are placed in the manual coating station outside pre- and / or post-coated the cabin. This makes the hand coater naturally a practically unlimited freedom for careful manual coating Not available even for very large side openings for manual coating would be achievable according to the prior art, and this without any additional effort at the same time increased hand coating quality.

Zum Ausleuchten der zu beschichtenden Stellen kann Tageslicht oder eine ohnehin vorhandene Werkstattbeleuchtung ausreichen. Zusätzlich können auch Lampen zur Ausleuchtung der Beschichtungsorte außen an der Kabine vorgesehen werden.Die unvermeidbare Beleuchtung innerhalb der Kabine kann so als Deckenbeleuchtung ausgeführt werden, d.h. an einer verschmutzungsunanfälligen Stelle angebracht werden.Daylight or an existing one can be used to illuminate the areas to be coated Workshop lighting is sufficient. In addition, lamps can also be used for illumination of the coating locations on the outside of the cabin. The inevitable lighting inside the cabin can be designed as ceiling lighting, i.e. at a pollution-prone place.

Durch die bevorzugte Anordnung des betreffenden Handbeschichtungsplatzes nahe der im Beschichtungsbetrieb stets offen gehaltenen Durchtrittsöffnung ist dafür Sorge getragen, daß praktisch kein beim Handbeschichten versprühtes Pulver in die Umgebung verloren geht; denn der Unterdruck in der Kabine sorgt für ein Einsaugen von überschüssigem, nicht zum Werkstück gelangenden Pulver durch die Durchtrittsöffnung in die Kabine hinein.Due to the preferred arrangement of the relevant hand coating station near the im Coating company always kept open opening is ensured that practically no powder sprayed during manual coating is lost in the environment; because the negative pressure in the cabin ensures that excess, not to, is sucked in Powder entering the workpiece through the passage opening into the cabin.

Ein zweiter Handbeschichtungsplatz stromabwärts von einer zweiten Durchtrittsöffnung für die Werkstücke in einer zweiten Stirnwand am stromabwärtigen Ende der Kabine ist dann von Vorteil, wenn Bedarf für ein Nachbeschichten oder eine Kontrolle nach der automatischen Beschichtung in der Kabine besteht. Dieser Handbeschichtungsplatz kann auch als einziger Handbeschichtungsplatz vorgesehen sein.A second hand coating station downstream from a second passage opening for The workpieces are then in a second bulkhead at the downstream end of the cabin an advantage if there is a need for a re-coating or a control after the automatic Coating in the cabin exists. This manual coating station can also be the only one Manual coating station should be provided.

Die in den Figuren gezeigte Kabine dient zur Beschichtung von strichpunktiert angedeuteten Werkstücken W, welche längs einer ebenfalls strichpunktiert gezeichneten Transportbahn T in Richtung des entsprechenden Pfeiles durch die Kabine kontinuierlich oder schrittweise gefördert werden. Die Kabine hat zwei Seitenwände 2, welche mit vertikalen Langlöchern 4 zum Durchlassen von in Fig. 1 angeordneten, vertikal beweglichen Automatik-Pulversprühpistolen 6 versehen sind. The cabin shown in the figures is used to coat dash-dotted lines Workpieces W, which along a likewise dash-dotted transport path T in Direction of the corresponding arrow through the cabin continuously or gradually promoted become. The cabin has two side walls 2, which with vertical slots 4 for Passing of vertically movable automatic powder spray guns arranged in FIG. 1 6 are provided.

Die Kabine hat ferner ein durch einen Längsspalt S geteiltes Kabinendach 8. Der Längsspalt lässt Aufhängevorrichtungen 10 für die Werkstücke W durch, um den Transport der Aufhängevorrichtungen 10 mit den daran hängenden Werkstücken W durch die Kabine längs der Transportbahn T zuzulassen.The cabin also has a cabin roof 8 divided by a longitudinal gap S. The longitudinal gap passes hangers 10 for workpieces W to facilitate the transportation of the hangers 10 with the workpieces W attached to it through the cabin along the Allow conveyor track T.

Die Kabine hat ferner einen Boden 12 sowie eine vordere Stirnwand 14, welche in den Fig. 1 und 3 gesehen am linken Ende der Kabine angeordnet ist, sowie eine hintere Stirnwand 20, welche am in den Fig. 1 und 3 gesehen rechten Ende der Kabine angeordnet ist. Die Stirnwand 14 hat eine große Durchtrittsöffnung 16, die deutlich größer als das Querprofil der Werkstücke W ist (s. Fig. 2). Diese Durchtrittsöffnung 16 ist durch eine Schiebetür 18 für den Reinigungsbetrieb verschließbar, über welche der begehbare Kabineninnenraum zugänglich ist.The cabin also has a floor 12 and a front end wall 14, which is shown in FIG. 1 and 3 seen at the left end of the cabin, and a rear end wall 20, which is arranged at the right end of the cabin as seen in FIGS. 1 and 3. The front wall 14 has a large passage opening 16, which is significantly larger than the cross section of the Workpieces W is (see Fig. 2). This passage opening 16 is through a sliding door 18 for the Lockable cleaning operation, through which the accessible cabin interior is accessible is.

Die hintere Stirnwand 20 hat eine Durchtrittsöffnung 19, die ebenso wie die Durchtrittsöffnung 16 zum Durchlassen der Werkstücke W aus der Kabine heraus bemessen sein kann. Eine Tür kann hier insbesondere dann fehlen, wenn eine Absaugung nahe der vorderen Stirnwand 14 vorgesehen ist.The rear end wall 20 has a passage opening 19 which, like the passage opening 16 to allow the workpieces W to be dimensioned out of the cabin. A In particular, the door can be missing here if there is an extraction system near the front end wall 14 is provided.

An die Stirnwand 14 anschließend ist ein insgesamt mit der Bezugszahl 30 bezeichneter Handbeschichtungsplatz mit einem auf Füßen 32 abgestützten, begehbaren Standboden 34 angeordnet, der oberhalb des Kabinenbodens 12 liegt und von der in Fig. 2 rechts liegenden Seite der Transportbahn T wandlos, also frei zugänglich ist. In Fig.2 auf der linken Seite ist eine Rückwand 36 vorgesehen, die in ihrem oberen Bereich zu einer Teilüberdachung 38 des Handbeschichtungsplatzes in den vier unterschiedlichen Ausformungen gemäß den Fig. 5a) bis 5d) abgeknickt ist und sich parallel zur Transportbahn T unmittelbar bis zum in Fig. 2 gesehen linken Rand des Spaltes S zum Durchlassen der Aufhängevorrichtung 10 für die Werkstücke W erstreckt. Die Schiebetür 18 ist in ihrem oberen, in Fig. 2 linken Bereich 18' der Kontur der Teilüberdachung 38 entsprechend profiliert. Da die Profilierung der Schiebetür 18 an diejenige von Rückwand 36 und Teilüberdachung 38 angepaßt ist, lässt sich durch Einsatz einer Dichtung 39 (in Fig. 5a) bis 5d) angedeutet) eine optimale Reinigungswirkung bei geschlossener Schiebetür 18 erreichen.Adjoining the end wall 14 is a reference numeral 30 overall Manual coating station with a walkable stand 34 supported on feet 32 arranged, which lies above the cabin floor 12 and of the one lying on the right in FIG. 2 Side of the transport path T is wallless, that is freely accessible. In Fig.2 is on the left a rear wall 36 is provided, which in its upper region forms a partial roof 38 of the Manual coating station in the four different designs according to FIG. 5a) to 5d) is kinked and seen parallel to the transport path T directly up to in Fig. 2 left edge of the gap S for passing the suspension device 10 for the workpieces W extends. The sliding door 18 is in its upper, in Fig. 2 left area 18 ' Contour of the partial roof 38 profiled accordingly. Since the profiling of the sliding door 18th is adapted to that of the rear wall 36 and partial canopy 38, by use a seal 39 (in Fig. 5a) to 5d) indicated) an optimal cleaning effect when closed Reach sliding door 18.

Wie aus den Figuren 2, 3 und 4 ersichtlich ist, schließt eine unterhalb des Standbodens 34 durchgeführte Absaugleitung 50 an eine Öffnung 52 in der vorderen Stirnwand 14 der Kabine an. Die Absaugleitung 50 ist mit einer nicht gezeigten Filter- oder Rückgewinnungseinheit für überschüssiges Pulver verbunden.As can be seen from FIGS. 2, 3 and 4, one closes below the base 34 performed suction line 50 to an opening 52 in the front end wall 14 of the cabin on. The suction line 50 is equipped with a filter or recovery unit, not shown excess powder linked.

Unmittelbar anschließend an die Stirnwand 20 ist ein zweiter Handbeschichtungsplatz 40 stromabwärts von der Kabine mit einem Standboden 44 auf Füßen 42 angeordnet, der von der entgegengesetzten Seite her zugänglich ist wie der Handbeschichtungsplatz 30 und ebenso wie dieser mit einer Rückwand 46 mit abgeknickter Teilüberdachung 48 versehen ist. Anstatt über die Öffnung 52 in der vorderen Stirnwand könnte die Absaugleitung 50 auch über eine Öffnung unterhalb des Standbodens 44 in der hinteren Stirnwand 22 an den Kabineninnenraum anschließen. Bei dem in Fig. 1 gezeigten Beispiel hat der Handbeschichtungsplatz 30 eine größere Abmessung L in Transportrichtung T gesehen als die entsprechende Abmessung 1 des Handbeschichtungsplatzes 40, weil nahe der Absaugöffnung 52 der Sog durch die Durchtrittsöffnung 16 in die Kabine hinein stärker ist als der Sog durch die Durchtrittsöffnung 19. Der Beschichter kann an diesem Ende der Kabine also in größerem Abstand von der Durchtrittsöffnung arbeiten als am anderen Ende der Kabine und hat entsprechend größeren Freiraum.Immediately following the end wall 20 is a second manual coating station 40 arranged downstream of the cabin with a stand 44 on feet 42 which of the opposite side is accessible like the manual coating station 30 and likewise how this is provided with a rear wall 46 with a bent partial canopy 48. Instead of Via the opening 52 in the front end wall, the suction line 50 could also have a Opening below the floor 44 in the rear end wall 22 to the cabin interior connect. In the example shown in FIG. 1, the manual coating station has 30 seen a larger dimension L in the transport direction T than the corresponding dimension 1 of the manual coating station 40 because near the suction opening 52 the suction through the Passage opening 16 into the cabin is stronger than the suction through the passage opening 19. The coater can therefore be at a greater distance from the end of the booth Passage opening work as at the other end of the cabin and has correspondingly larger ones Free space.

Bevorzugt bestehen mindestens die Kabinenwände 2, 14 20, das Kabinendach 8 und die Rückwände 36, 38 bzw. 46, 48 aus einem elektrisch nicht leitenden Material.Preferably there are at least the cabin walls 2, 14 20, the cabin roof 8 and the Rear walls 36, 38 and 46, 48 made of an electrically non-conductive material.

Im Betrieb der Kabine werden Werkstücke W in den Fig. 1 und 3 gesehen von links nach rechts durch die Kabine kontinuierlich oder schrittweise gefördert. Gleichzeitig mit dem automatischen Beschichten mittels der Automatik-Sprühpistolen 6 im Kabineninnenraum vorbeschichtet ein auf dem Standboden 34 stehender oder sitzender Handbeschichter ein noch außerhalb der Kabine befindliches Werkstück W an kritischen Stellen. In gleicher Weise kann ein weiterer Handbeschichter aus der Kabine austretende, fehlerhaft oder unvollständig beschichtete Werkstücke W an dem Handbeschichtungsplatz 40 nachbeschichten. Die Handbeschichter können dabei ihre Handbeschichtungs-Sprühpistole mit praktisch unbegrenztem Freiraum außerhalb des Kabineninnenraumes handhaben, wobei die Werkstücke an den zu beschichtenden Stellen durch am Kabinendach außen angebrachte Lampen beleuchtbar sein können. During operation of the cabin, workpieces W are seen from left to right in FIGS. 1 and 3 conveyed continuously or gradually through the cabin on the right. Simultaneously with the automatic Coating pre-coated using the automatic spray guns 6 in the cabin interior a hand coater standing or sitting on the stand 34 still outside workpiece W located in the cabin at critical points. In the same way another hand coater emerging from the booth, coated incorrectly or incompletely Recoat workpieces W at the manual coating station 40. The hand coater can do their hand coating spray gun with practically unlimited Handle free space outside the cabin, with the workpieces on the coating areas can be illuminated by lamps attached to the outside of the cabin roof can.

Durch den Sog in die Durchtrittsöffnung 16 bzw. 19 in den jeweiligen Stirnwänden 14, 20 in die Kabine hinein wird überschüssiges, beim Handbeschichten nicht auf die jeweiligen Werkstücke W gelangendes Pulver in diese Durchtrittsöffnungen hinein gesaugt.Through the suction into the passage opening 16 or 19 in the respective end walls 14, 20 in the cabin inside becomes excess, with manual coating not on the respective workpieces W incoming powder is sucked into these openings.
