Bei der in Fig. 1 gezeigten Ausführungsform nach der Erfindung sind äußere Bodenklappen 2 und 4 benachbart zu äußeren Längswänden 6 und 8 angeordnet und um eine sich in Längsrichtung erstreckende Drehachse 10 bzw. 12 drehbar angeordnet. Zwischen den äußeren Bodenklappen 2, 4 und den ihnen benachbarten äußeren Längswänden 6, 8 ist jeweils ein sich in Längsrichtung erstreckender äußerer Bodenlängsspalt 14 bzw. 16 gebildet.At the in Fig. 1 shown embodiment, according to the invention, outer bottom flaps 2 and 4 are arranged adjacent to outer longitudinal walls 6 and 8 and rotatably disposed about a longitudinally extending axis of rotation 10 and 12, respectively. Between the outer bottom flaps 2, 4 and the outer longitudinal walls 6, 8 which are adjacent to them, in each case a longitudinally extending outer longitudinal longitudinal gap 14 or 16 is formed.

In dem zwischen den beiden äußeren Bodenklappen 2 und 4 gelegenen Bodenbereich ist mindestens ein weiterer Bodenteil 18 vorgesehen, welcher oder von welchen einer in Kabinenquerrichtungsmitte als Bodenmittelteil angeordnet ist. Bei der Ausführungsform nach Fig. 1 ist der weitere Bodenteil gleichzeitig der Bodenmittelteil 18. Ein innerer Bodenlängsspalt 20 bzw. 22 ist jeweils zwischen der äußeren Bodenklappe 2, 4 und dem ihr benachbarten mindestens einen Bodenteil gebildet, welch letzterer in Fig. 1 der Bodenmittelteil 18 ist.At least one further bottom part 18 is provided in the bottom area located between the two outer bottom flaps 2 and 4, which is arranged as a bottom middle part or from which one in the cabin transverse direction center. In the embodiment according to Fig. 1 an inner bottom longitudinal gap 20 or 22 is formed in each case between the outer bottom flap 2, 4 and its adjacent at least one bottom part, which latter in Fig. 1 the bottom middle part 18 is.

Die Weite der äußeren und inneren Bodenlängsspalte 14, 16, 20 und 22 ist durch Drehen der ihnen benachbarten Bodenklappen, im vorliegenden Falle der äußeren Bodenklappen 2 und 4 um ihre Drehachsen 10 bzw. 12 verstellbar.The width of the outer and inner bottom longitudinal gaps 14, 16, 20 and 22 is adjustable by turning the bottom flaps adjacent thereto, in the present case the outer bottom flaps 2 and 4 about their axes of rotation 10 and 12 respectively.

Die eine äußere Bodenklappe 2 und die ihr benachbarten Längsspalten 14 und 20 überdecken einen Absaugkanal 26, welcher sich in Kabinenlängsrichtung vorzugsweise über die gesamte Kabinenlänge erstreckt. Die andere äußere Bodenklappe 4 und die ihr benachbarten Längsspalten 16 und 22 überdecken einen weitern Absaugkanal 28, welcher sich in Kabinenlängsrichtung vorzugsweise über die gesamte Kabinenlänge erstreckt.The one outer bottom flap 2 and the adjacent longitudinal columns 14 and 20 cover a suction channel 26, which preferably extends in the cabin longitudinal direction over the entire length of the cabin. The other outer bottom flap 4 and the adjacent longitudinal columns 16 and 22 cover a further suction channel 28, which preferably extends in the cabin longitudinal direction over the entire length of the cabin.

Die beiden Absaugkanäle 26 und 28 sind über Fluidleitungen 30 bzw. 32 an eine Pulverabsaugvorrichtung 34, vorzugsweise eine Pulverrückgewinnungsvorrichtung angeschlossen. Am Ausgang der Absaugkanäle 26 und 28 oder in den Fluidleitungen 30 und 32 kann sich eine Strömungsdrossel 36 bzw. 38 befinden, so dass durch Schließen einer der beiden Strömungsdrosseln die Saugwirkung in der betreffenden anderen Fluidleitung und damit in dem betreffenden anderen Absaugkanal 26 oder 28 erhöht wird. Die Pulverabsaugvorrichtung kann beliebig ausgebildet sein. Sie enthält beispielsweise einen Zyklon 40 zur Abscheidung von zurückgewonnenem Überschusspulver 42, ein Saug-Gebläse 44 und einen Abluftfilter 46, durch welchen die aus der Pulversprühbeschichtungskabine abgesaugte Luft in die freie Atmosphäre abgegeben werden kann.The two suction channels 26 and 28 are connected via fluid lines 30 and 32, respectively, to a powder suction device 34, preferably a powder recovery device. At the outlet of the suction channels 26 and 28 or in the fluid lines 30 and 32 may be a flow restrictor 36 and 38, so that increases by closing one of the two flow throttles, the suction in the relevant other fluid line and thus in the respective other suction channel 26 or 28 becomes. The powder suction device can be designed as desired. It contains, for example, a cyclone 40 for the removal of recovered excess powder 42, a suction fan 44 and an exhaust filter 46, by means of which the air extracted from the powder spray coating booth can be discharged into the free atmosphere.

In Fig. 1 ist der mittlere Bodenteil 18 als von einer Person begehbarer Bodenteil stabil ausgebildet. Der begehbare Bodenteil 18 ist auf seiner Oberseite mit Druckluftauslässen 50 zum Blasen von Druckluft 52 über die Oberfläche 54 des begehbaren Bodenteils 18 in Richtung zu mindestens einem, gemäß Fig. 1 in Richtung zu den beiden inneren Bodenlängsspalten 20 bzw. 22 versehen.In Fig. 1 is the middle bottom part 18 formed as walkable by a person bottom part. The walk-on bottom part 18 is on its upper side with compressed air outlets 50 for blowing compressed air 52 over the surface 54 of the accessible floor part 18 in the direction of at least one, according to Fig. 1 provided in the direction of the two inner bottom longitudinal gaps 20 and 22, respectively.

Die Druckluftauslässe 50 sind an eine Druckluftquelle 56 anschließbar, beispielsweise einen Druckregler oder ein anderes Druckeinstellelement, welches seinerseits an einem Druckluftspender angeschlossen ist, beispielsweise ein Druckluftnetz oder an einem Druckluftbehälter.The compressed air outlets 50 can be connected to a compressed air source 56, for example a pressure regulator or another pressure adjusting element, which in turn is connected to a compressed air dispenser, for example a compressed air network or to a compressed air tank.

Fig. 1 zeigt die beiden äußeren Bodenklappen 2 und 4 in einer horizontalen Drehposition, in welcher die Bodenlängsspalten 14, 16, 20 und 22 ihre kleinste Weite haben. Die äußeren Bodenklappen 2 und 4 sind derart ausgebildet, dass ihre Oberfläche in dieser Position mit der Oberfläche 54 des begehbaren Bodenteils 18 fluchtet. Beim Sprühen von Beschichtungspulver abfallendes Überschusspulver kann durch die Bodenlängsspalten 14, 16, 20 und 22 in die Absaugkanäle 26 und 28 fallen. Fig. 1 shows the two outer bottom flaps 2 and 4 in a horizontal rotational position in which the bottom longitudinal gaps 14, 16, 20 and 22 have their smallest width. The outer bottom flaps 2 and 4 are formed such that their surface is aligned in this position with the surface 54 of the accessible floor part 18. In the spraying of coating powder sloping excess powder can fall through the bottom longitudinal gaps 14, 16, 20 and 22 in the suction channels 26 and 28.

Zum Reinigen der Pulversprühbeschichtungskabine können die Bodenklappen 2 und 4 in eine Schrägstellung gedreht werden, wie dies beispielsweise in Fig. 1 durch eine gestrichelt dargestellte Position der Bodenklappe 4 gezeigt ist. Dadurch kann einen Person, welche die Pulversprühbeschichtungskabine mittels einer Druckluftpistole oder Druckluftlanze mit Druckluft ausbläst, auch in die Absaugkanäle26 und 28 hinein sehen, um deren Sauberkeit zu überprüfen. Auch können die Bodenklappen 2, 4 so weit gedreht werden, dass auch ihre Unterseite mit Druckluft abgeblasen werden kann.To clean the powder spray coating booth, the bottom flaps 2 and 4 can be rotated in an inclined position, as for example in Fig. 1 is shown by a dashed line position of the bottom flap 4. As a result, a person who blows the powder spray coating booth by means of a compressed air gun or compressed air lance with compressed air, also see in the Absaugkanäle26 and 28 in order to check their cleanliness. Also, the bottom flaps 2, 4 are rotated so far that their bottom can be blown off with compressed air.

Die Ausführungsform von Fig. 2 ist identisch mit der von Fig. 1, mit der Ausnahme, dass die äußeren Bodenklappen 2 und 4, wenn sie auf kleinste Weite der ihnen benachbarten Bodenlängsspalten 14, 16 eingestellt sind, höher angeordnet sind als die Oberfläche 54 des begehbaren Bodenteils 18, wobei zumindest die Unterseiten 60 der Bodenklappen 2, 4 an ihrem inneren Ende höher angeordnet sind als die Oberfläche 54 des begehbaren Bodeteils 18, so dass diese Flügelunterseiten 60 von der Druckluft 52 weggeblasenes Pulver in die Absaugkanäle 26 bzw. 28 leiten.The embodiment of Fig. 2 is identical to that of Fig. 1 with the exception that the outer bottom flaps 2 and 4, when adjusted to the smallest width of the floor longitudinal gaps 14, 16 adjacent to them, are arranged higher than the surface 54 of the walk-on bottom part 18, wherein at least the undersides 60 of the bottom flaps 2, 4 are arranged at their inner end higher than the surface 54 of the walkable bottom part 18, so that these wing bottoms 60 lead away from the compressed air 52 blown powder into the suction channels 26 and 28 respectively.

Fig. 2 zeigt die Bodenklappen 2 und 4 in ausgezogenen Linien in einer horizontalen Ausrichtung während des Sprühbeschichtungsbetriebes, und in gestrichelten Linien in einer Schrägstellung zum Reinigen der Pulversprühbeschichtungskabine. In dar in Fig. 2 gestrichelt gezeichneten Schrägstellung der Bodenklappen 2 und 4 kann eine Bedienungsperson bis in die unteren Ecken der Absaugkanäle 26 und 28 sehen und beobachten, ob auch die Absaugkanäle sauber gereinigt werden. Auch besteht die Möglichkeit, die Bodenklappen 2 und 4 um 180° drehbar zu gestalten, damit ihre Unterseiten nach oben gedreht werden und dann ebenfalls mit Druckluft abgeblasen werden können zum Reinigen vor einem Farbwechsel (Pulverwechsel). Fig. 2 Figure 9 shows the bottom flaps 2 and 4 in solid lines in a horizontal orientation during the spray coating operation, and in dashed lines in an inclined position for cleaning the powder spray coating booth. In dar in Fig. 2 Dashed line inclined position of the bottom flaps 2 and 4 can see an operator to the bottom corners of the suction channels 26 and 28 and observe whether the suction ducts are cleaned clean. It is also possible to make the bottom flaps 2 and 4 rotatable by 180 °, so that their Bottoms are turned up and then can also be blown off with compressed air for cleaning before a color change (powder change).

Die in den Fig. 3, 4 und 5 dargestellte Pulversprühbeschichtungskabine 62 ist in ihrem unteren Bereich entsprechend den Fig. 1 und 2 ausgebildet oder mit einem Unterbau nach den Fig. 1 oder 2 versehen. Beschichtungsobjekte 64 sind von einer Hänge-Fördervorrichtung 66 in Bewegungsrichtung 68 in Längsrichtung durch die Pulversprühbeschichtungskabine 62 hindurch transportierbar und in ihr durch Automatikpistolen 70 mit Pulver besprühbar. Außerhalb der Sprühbeschichtungskabine kann sich an deren Eingängen und Ausgängen 72 bzw. 74 jeweils ein Freihand-Sprühbeschichtungsplatz 76 bzw. 78 befinden.The in the Fig. 3, 4 and 5 shown powder spray coating booth 62 is in its lower portion corresponding to Fig. 1 and 2 trained or with a substructure after the Fig. 1 or 2 Mistake. Coating objects 64 are transportable longitudinally from the overhead conveyor 66 in the direction of travel 68, through the powder spray coating booth 62, and sprayed therein by powder guns 70 through automatic spray guns. Outside the spray booth, there may be a freehand spray booth 76 and 78, respectively, at their entrances and exits 72 and 74, respectively.

Wie die Fig. 6, 7, 8 und 9 zeigen, sind die Bodenklappen 2 und 4 der Sprühbeschichtungskabine 62 von einem Antrieb 80 in verschiedene Drehpositionen um eine in Kabinenlängsrichtung verlaufende Drehachse 10 bzw. 12 drehbar. Alternativ kann für jede Bodenklappe eigener Antrieb vorgesehen sein oder für alle Bodenklappen ein gemeinsamer Antrieb vorgesehen sein. Der Antrieb 80 kann ein Elektromotor oder Pneumatikmotor oder Hydraulikmotor sein, vorzugsweise ein Zylinder mit einem vor- und zurückbewegbaren Stößel 82, um die betreffende Bodenklappe 2 und/oder 4 jeweils in die eine oder andere Richtung zu drehen.As the 6, 7, 8 and 9 show the bottom flaps 2 and 4 of the spray coating booth 62 by a drive 80 in various rotational positions about a longitudinal axis extending in the cabin rotation axis 10 and 12 rotatable. Alternatively it can be provided for each bottom flap own drive or be provided for all bottom flaps a common drive. The drive 80 may be an electric or pneumatic motor or hydraulic motor, preferably a cylinder with a plunger 82 that can be moved back and forth to rotate the respective bottom flap 2 and / or 4 in either direction.

Die Bodenklappen 2 und 4 können auf ihrer Oberseite ebenfalls mit Druckluftauslässen 50 versehen sein zum Blasen von Druckluft in die eine oder andere benachbarte Bodenlänggspalte 14, 16, 20 und 22. Meistens reichen jedoch Druckluftauslässe 50 auf dem begehbaren Bodenteil 18 zum Reinigen auch der Oberflächen der Bodenklappen 2 und 4.The bottom flaps 2 and 4 may also be provided on their upper side with compressed air outlets 50 for blowing compressed air into one or the other adjacent Bodenlänggspalte 14, 16, 20 and 22. Usually, however, compressed air outlets 50 on the accessible floor part 18 for cleaning also the surfaces of Bottom flaps 2 and 4.

Die Druckluft kann den Druckluftauslässen 50 der Bödenklappen 2 und 4 vorzugsweise durch einen Druckluftweg 84 zugeführt werden, welcher sich axial zur Drehachse 10 bzw. 12 in die betreffende Bodenklappe 2 bzw. 4 hinein und innerhalb der Bodenklappe quer zur Drehachse bis zur Oberseite dieser Bodenklappe erstreckt.The compressed air can be supplied to the compressed air outlets 50 of the bottom flaps 2 and 4 preferably by a compressed air path 84 which extends axially to the axis of rotation 10 and 12 in the respective bottom flap 2 and 4 and within the bottom flap transverse to the axis of rotation to the top of this bottom flap ,

In der Pulversprühbeschichtungskabine befindet sich in ihrem unteren Bereich, welcher als Unterbau der Kabine ausgebildet sein kann, an mindestens einem, vorzugsweise an beiden Längsenden eine Absaugöffnung 92, 94, 96, 98 im Kabinenboden über jeweils einem der Absaugkanäle 26 bzw. 28. Diese Absaugöffnungen sind vorzugsweise benachbart zu den Stirnseiten der äußeren Bodenklappen 2, 4 diesen gegenüber liegend gebildet, wie dies Fig. 8 schematisch zeigt.In the powder spray coating booth is located in its lower region, which may be formed as a substructure of the cabin, at least one, preferably at both longitudinal ends of a suction opening 92, 94, 96, 98 in the cabin floor via one of the suction channels 26 and 28. These suction are preferably adjacent to the end faces of the outer bottom flaps 2, 4 formed lying opposite this, as Fig. 8 schematically shows.

Gemäß der in Fig. 12 und 13 gezeigten Ausführungsform der Erfindung können die Absaugöffnungen anstatt stirnseitig von den Bodenklappen 2, 4 oder zusätzlich, an den Längsenden des begehbaren mittleren Bodenteils 18 gebildet sein, wie dies in Fig. 13 für Absaugöffnungen 100 und 102 gezeigt ist. Die Fig. 12 und 13 zeigen eine im Horizontalquerschnitt zylindrisch runde Kabine, während die anderen Figuren eine im Horizontalquerschnitt rechteckige Kabine zeigen.According to the in FIGS. 12 and 13 1, the suction openings may be formed instead of the front side of the bottom flaps 2, 4 or in addition, at the longitudinal ends of the accessible middle bottom part 18, as shown in Fig. 13 for suction openings 100 and 102 is shown. The FIGS. 12 and 13 show a cylindrical cross-section in the horizontal cross-section cabin, while the other figures show a rectangular in horizontal cross-section cabin.

Fig. 14 zeigt eine der Fig. 2 ähnliche Ausführungsform mit der Ausnahme, dass in Fig. 14 der innere Klappenteil 112 bzw. 114 der beiden Bodenklappen 2 und 4 den benachbarten Bodenteil 18 überlappt, wenn die Bodenklappen 2 bzw. 4 auf eine kleinste Weite der Bodenlängsspalte 14, 16, 20 und 22 eingestellt sind. Dadurch wird die Pulverabsaugwirkung in horizontaler Richtung verstärkt, jedoch in vertikaler Richtung zu den Beschichtungsobjekten reduziert. Dies hat eine Reduzierung der Störung der Sprühbeschichtungswolke zur Folge, welche auf die Beschichtungsobjekte gesprüht wird. Fig. 14 shows one of the Fig. 2 similar embodiment with the exception that in Fig. 14 the inner flap part 112 or 114 of the two bottom flaps 2 and 4 overlaps the adjacent bottom part 18 when the bottom flaps 2 and 4 are set to a smallest width of the bottom longitudinal gaps 14, 16, 20 and 22. Thereby, the powder suction effect is increased in the horizontal direction but reduced in the vertical direction to the coating objects. This results in a reduction in the disturbance of the spray coating cloud which is sprayed onto the coating objects.

Bei der in Fig. 10 gezeigten Ausführungsform des unteren Abschnittes oder eines Unterbaus einer Pulversprühbeschichtungskabine nach der Erfindung ist wiederum der Bodenmittelteil als der begehbare Bodenteil 18 ausgebildet.
