The coating guns are supported by pivotable holders.

Description

Die Erfindung betrifft eine Pulverbeschichtungskabine mit wenigstens einem drehbaren Kabinenwandträger, der mehrere Wandelemente aufnimmt, die wenigstens zwei Kabinensegmente bilden, wobei der Kabinenwandträger mehrere sich in etwa radial von einer Drehachse erstreckende Seitenwandelemente aufnimmt und wenigstens ein zu den Kabinensegmenten komplementär ausgebildetes, verfahrbares und/oder verschiebbares Abschlußelement vorgesehen ist, das mit jeweils einem durch mehrere Wandelemente begrenzten Kabinensegment einen wenigstens teilweise geschlossenen Beschichtungsraum bildet, wobei die Seitenwandelemente wenigstens an ihren von der Drehachse des Kabinenwandträgers abliegenden sich vertikal erstreckenden Kanten mit Reinigungselementen versehen sind, das Abschlußelement eine konkav zylindrische Kabineninnenwand bildet und das Abschlußelement bzgl. des Kabinenwandträgers so verfahrbar und/oder verschiebbar ist, daß die mit Reinigungselementen versehenen Kanten der Seitenwandelemente bei einer Drehung des Kabinenwandträgers die Innenwand des Abschlußelements bestreichen, wobei weiterhin zum Einbringen des Beschichtungspulvers in die Beschichtungskabine an schwenkbaren Pistolenträgern angeordnete Pulverpistolen vorgesehen sind.The invention relates to a powder coating booth at least one rotatable cabin wall support, the multiple Includes wall elements, the at least two cabin segments form, the cabin wall support several approximately radially receives side wall elements extending from an axis of rotation and at least one complementary to the cabin segments trained, movable and / or displaceable closure element is provided, each with one by several Wall elements limited at least partially a cabin segment forms a closed coating space, the side wall elements at least on their from the axis of rotation of the Cabin wall support lying vertically extending Edges are provided with cleaning elements, the final element forms a concave cylindrical interior wall and the closing element can be moved with respect to the cabin wall support and / or is displaceable that the cleaning elements provided edges of the side wall elements when the Paint the cabin wall girder on the inside wall of the end element, wherein further for introducing the coating powder into the coating booth on swiveling gun carriers arranged powder guns are provided.

Eine gattungsgemäße Pulverbeschichtungskabine ist der DE 197 22 773 C1 zu entnehmen.A generic powder coating booth is the DE 197 22 773 C1.

Bei dieser Pulverbeschichtungskabine sind die Pulverpistolen an geraden Pistolenträgern angeordnet, die auf drehbaren Pistolenstöcken sitzen. Durch ein Drehen der Pistolenstöcke können die Pulverpistolen durch einen Spalt in den Beschichtungsraum eingeschwenkt werden und das Beschichtungsgut beidseitig mit Pulvermaterial beaufschlagen.With this powder coating booth are the powder guns arranged on straight pistol supports, which are on rotatable pistol sticks sit. By turning the pistol sticks can the powder guns through a gap in the coating room be swung in and the coating material on both sides apply powder material.

Bei dieser Art der Pulverapplikation ist ein optimaler Abstand zwischen der Pulverpistole und dem Beschichtungsgut jedoch nur schwer zu erreichen, außerdem kann die Menge des sogenannten "Overspray", das aus der Beschichtungskabine entfernt werden muß, relativ hoch sein.With this type of powder application there is an optimal distance between the powder gun and the coating material, however, only difficult to reach, moreover, the amount of the so-called "Overspray" to be removed from the coating booth must be relatively high.

Der Erfindung liegt demzufolge die Aufgabe zugrunde, eine gattungsgemäße Pulverbeschichtungskabine derart weiterzubilden, daß die Pulverapplikation auf das Beschichtungsgut optimiert und die Menge des anfallenden "Overspray" reduziert ist.The invention is therefore based on the object to further develop generic powder coating booths in such a way that the powder application on the coating material is optimized and the amount of "overspray" is reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Pistolenträger als S-förmig gekrümmte Haltearme ausgebildet sind.This object is achieved in that the Gun holder designed as S-shaped curved arms are.

Durch diese speziellen Haltearme gelingt es nunmehr, die Pulverpistolen in den Spalt um eine außerhalb der Pulverbeschichtungskabine befindliche vertikale Achse derart einzuschwenken, daß sie sich innerhalb der Beschichtungskabine in einem optimalen Abstand und Winkel zum Beschichtungsgut befinden. Infolgedessen kann die Gleichmäßigkeit und Dicke des Pulverauftrages optimiert werden, wobei gleichzeitig die Menge des Overspray reduziert wird.These special holding arms now make it possible to use the powder guns in the gap around an outside of the powder coating booth swivel the vertical axis in such a way that they are in an optimal inside the coating booth Distance and angle to the coating material. Consequently can the uniformity and thickness of the powder application can be optimized, while at the same time the amount of Overspray is reduced.

Bei der erfindungsgemäßen Vorrichtung können mehrere Pulverpistolen neben- oder übereinander an dem S-förmig gekrümmten Haltearm mittels entsprechender Pistolenstöcke angeordnet sein, eine gleichmäßige und qualitativ hochwertige Beschichtung kann jedoch auch nur mit einer Pistole erfolgen, wenn der S-förmig gekrümmte Haltearm mit einem außerhalb der Beschichtungskabine befindlichen Hubgerät verbunden ist, das den Haltearm und damit die Pulverpistole mit an die Produktionsgeschwindigkeit angepaßter Geschwindigkeit in vertikaler Richtung anhebt und absenkt.In the device according to the invention, several powder guns can be used side by side or one above the other on the S-shaped curved Holding arm arranged using appropriate pistol sticks be an even and high quality coating can only be done with a pistol if the S-shaped curved arm with one outside the coating booth located lifting device is connected to the holding arm and thus the powder gun to the production speed adjusted speed in the vertical direction raises and lowers.

Durch unterschiedliche Hubgeschwindigkeiten des Hubgerätes kann in Verbindung mit der Durchlaufgeschwindigkeit des Beschichtungsgutes die Beschichtungsdicke auf einfache Art und Weise eingestellt werden.Due to different lifting speeds of the lifting device can in connection with the throughput speed of the coating material the coating thickness in a simple manner and Way to be set.

Ein weiterer Vorteil der S-förmig gekrümmten Haltearme für die Pulverpistolen besteht darin, daß der von der Transportvorrichtung für das Beschichtungsgut durchsetzte Spalt zwischen dem Abschlußelement und den sternförmigen Kabinenwänden in Arbeitsstellung sehr gering gehalten werden kann, da der S-förmige Bogen des Haltearmes sehr eng um die Außenkanten der Kabinenwand geführt werden kann.Another advantage of the S-shaped curved arms for the Powder guns is that of the transport device gap between the coating material the closing element and the star-shaped cabin walls in Working position can be kept very low because of the S-shaped Arch of the support arm very tight around the outer edges of the Cabin wall can be guided.

Auch die Reinigung der Arme bzw. der Pulverpistolen ist bei der vorgeschlagenen Ausführung sehr einfach dadurch möglich, daß die Haltearme bei entsprechender Stellung der Kabinenwände aus dem Beschichtungsraum herausgeschwenkt und gereinigt bzw. ausgewechselt werden können.The cleaning of the arms and the powder guns is also included of the proposed design very easily possible that the holding arms with the appropriate position of the cabin walls swung out of the coating room and cleaned or can be replaced.

Das Gelenk zum Verschwenken der S-förmigen Haltearme um eine vertikale Achse ist vorzugsweise dort angebracht, wo die Haltearme mit dem Hubgerät verbunden sind.The joint for pivoting the S-shaped holding arms by one vertical axis is preferably located where the holding arms are connected to the lifting device.

Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht und wird im nachfolgenden anhand der Zeichnung im einzelnen erläutert.The invention is illustrated in the drawing, for example and will be described in detail below with reference to the drawing explained.

Die Zeichnungsfigur zeigt schematisch drei sternförmig an einem drehbaren Kabinenwandträger 1 angeordnete Kabinenwände 2, 3 und 4, die gemeinsam mit einer teilkreisförmigen Kabinenwand 5, auch als Abschlußelement bezeichnet, einen Beschichtungsraum 6 bilden. Zwischen den Außenkanten der Kabinenwände 2 und 3 und dem Abschlußelement 5 ist ein Spalt 7 vorhanden, der von einer Transportvorrichtung 8 durchgriffen wird, die das nicht dargestellte Beschichtungsgut trägt. The drawing figure schematically shows three in a star shape a rotatable cabin wall support 1 arranged cabin walls 2, 3 and 4 together with a semi-circular cabin wall 5, also referred to as a closing element, a coating room 6 form. Between the outer edges of the cabin walls 2 and 3 and the closing element 5 there is a gap 7, which is penetrated by a transport device 8, the carries the coating material, not shown.

Beidseitig zum Beschichtungsgut befinden sich jeweils auf der Ein- bzw. Auslaufseite im Inneren des Beschichtungsraumes 6 Pulverpistolen 9, 10, die an einem S-förmig gekrümmten Pistolenträger bzw. Haltearm 11, 12 angeordnet sind. Die Haltearme 11, 12 sind um vertikale Achsen 13, 14 verschwenkbar und werden vom Tragarm 15, 16 eines Hubgerätes 17, 18 getragen.
