Das in den bekannten Kabinen versprühte, nicht am Objekt haftende Pulver fällt zum größten Teil auf den Kabinenboden, während ein kleiner Anteil an den Kabinenwänden haftet. Dieses am Objekt nicht haftende Überschusspulver kann vom Kabinenboden abgesaugt und mittels Pulverabscheidung, insbesondere Zyklon und/oder Filterelemente, aus dem Saugluftstrom getrennt, dann gesiebt und anschließend mit frischem Pulver vermischt werden, bevor es der Sprühvorrichtung zugeführt und erneut versprüht wird. Beim Farbwechsel (Wechsel von einer Pulversorte auf eine andere Pulversorte) müssen nicht nur sämtliche Kabinen-Innenflächen, sondern auch die Zyklone und Filtereinrichtungen sowie die Pulververleitungen äußerst genau gereinigt werden, damit keine Pulverpartikel des zuerst verwendeten Pulvers mit dem danach verwendeten Pulver vermischt werden. Bereits einzelne Pulverpartikel können zu Beschichtungsfehlern auf dem Objekt führen, welche die Beschichtung unbrauchbar machen. Man denke nur an den Wechsel von einem schwarzen oder roten Pulver auf weißes Pulver oder umgekehrt. Die zu beschichtenden Objekte können Haushaltsgeräte oder Autokarroserien sein, deren Käufer keine Farbfehler dulden. Die Rückgewinnung des Überschusspulvers reduziert zwar die Herstellkosten, geblieben ist jedoch weiterhin das Problem, dass bei einem Farbwechsel sehr viel Zeit und/oder zusätzliche Anlagenteile (zum Beispiel austauschbare Pulverabscheider, Siebvorrichtungen, Fluidleitungen) benötigt werden, um lange Stillstandzeiten der Anlage zu vermeiden. Hieraus ist ersichtlich, dass bei Vielfarbenbeschichtungen und dann, wenn Objekte mit verschiedenen Farben beschichtet werden sollen, der genannte Sprühbeschichtungsbetrieb mit Rückgewinnung des Überschusspulvers unrentabel wird und auf Verlust gefahren werden muss. „Auf Verlust fahren" bedeutet, dass das Überschusspulver nicht aufbereitet und wieder verwendet, sondern als Abfall weggeworfen wird. Das Reinigen ist umso schwerer und zeitaufwendiger, je mehr das Pulver sich in der Kabine und den anderen Teilen ablagern kann. Aus diesem Grunde werden anstelle von Metallkabinen Kunststoffkabinen verwendet, da an ihnen die Pulverpartikel weniger stark und in geringerer Menge haften als in Metallkabinen. Die Pulverpartikel bestehen meistens aus Kunststoff, können jedoch auch aus Keramik oder einem anderen Material bestehen.The sprayed in the known cabins, not adhering to the object powder falls for the most part on the cabin floor, while a small proportion adheres to the cabin walls. This surplus powder, which does not adhere to the object, can be sucked from the cabin floor and removed from the suction by means of powder separation, in particular cyclone and / or filter elements separated air stream, then screened and then mixed with fresh powder before it is fed to the spray device and sprayed again. When changing color (changing from one type of powder to another type of powder), not only all the interior surfaces of the cabin, but also the cyclones and filtering devices and the powder feeds must be cleaned extremely precisely so that no powder particles of the powder used first are mixed with the powder used afterwards. Even individual powder particles can lead to coating defects on the object, which render the coating unusable. Just think of the change from a black or red powder to white powder or vice versa. The objects to be coated may be household appliances or car batches whose buyers do not tolerate color aberrations. Although the recovery of the excess powder reduces the manufacturing costs, but remains the problem that in a color change a lot of time and / or additional parts of the system (for example, interchangeable Pulverabscheider, screening devices, fluid lines) are needed to avoid long downtime of the system. From this it can be seen that in multi-color coatings and when it is desired to coat objects of different colors, said spray coating operation becomes unprofitable with recovery of the excess powder and must be run for loss. "Drive on loss" means that the excess powder is not recycled and reused, but is thrown away as waste, and cleaning becomes more difficult and time consuming as the powder settles in the cabin and other parts The powder particles are mostly made of plastic, but may also be made of ceramic or other material.
Durch die Erfindung soll die Aufgabe gelöst werden, den für einen Farbwechsel oder Pulverwechsel erforderlichen Zeitaufwand und/oder Aufwand an zusätzlichen Anlagenteilen weiter zu reduzieren, ohne auf eine gute Beschichtungsqualität verzichten zu müssen. Durch die Erfindung soll erreicht werden, dass eine Sprühbeschichtungsvorrichtung sowohl von den Herstellungskosten als auch für den Beschichtungsbetrieb auch dann rentabel ist, wenn sie wechselweise für lange Betriebsperioden mit gleich bleibender Pulversorte und dann wieder mit häufig wechselnden Pulversorten verwendet wird.By the invention aims to be solved the task for a Color change or powder change required time and / or Overhead of additional Plant parts continue to reduce without sacrificing a good coating quality to have to. The invention is intended to achieve that a spray coating device both from the manufacturing costs as well as for the coating operation is profitable even if they are the same for long periods of operation remaining powder and then again with frequently changing powder types is used.
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale von Anspruch 1 gelöst.These Task is carried out according to the invention the features of claim 1 solved.
