Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Puderabsaugung an Druckmaschinen, insbesondere zur Reinigung der Greiferwagen von anhaftenden Puder.The The invention relates to a device for powder extraction on printing presses, in particular for cleaning the gripper carriage of adhering powder.

Die Aufgabe der Erfindung besteht deshalb in der Schaffung einer derartigen Einrichtung, die entsprechend der erforderlichen Absaugung die jeweiligen Flächenelemente optimaler mit zur Aufwirbelung dienender Druckluft beaufschlagt, die dazu erforderlichen Druckstufen der Luftverdichter niedriger werden und dadurch der materialmäßige und der Energieaufwand minimiert wird.The The object of the invention is therefore to provide such Device, according to the required suction the respective surface elements optimal impinged with serving for fluidizing compressed air, the required pressure levels of the air compressor lower and thereby the material and the energy consumption is minimized.
Gelöst wird diese Aufgabe durch die beschreibenden Merkmale der erfindungsgemäßen Lösung nach Anspruch 1. Vorteilhafte Weiterbildungen der Einrichtung werden mit den Ansprüchen 2 bis 6 beschrieben. Durch die steuerbare Bewegung der Druckluftzuführung und die Steuerung der Stärke des Druckes der Druckluft können die Aufwirbelungen der Puderablagerungen optimal an den jeweiligen vorgegebenen Flächenelementen vorgenommen werden. Der erforderliche Systemvordruck und der Druckluftverbrauch für den Absaug- und Aufwirbelungsvorgang können so reduziert werden. Die abzusaugenden Flächen werden gleichmäßig und lückenlos bei einem optimalen Energieeinsatz zwecks Aufwirbelung mit Druckluft beaufschlagt.Is solved this task by the descriptive features of the solution according to the invention Claim 1. Advantageous developments of the device will be with the claims 2 to 6 described. Due to the controllable movement of the compressed air supply and the control of strength the pressure of the compressed air can the whirling up of the powder deposits optimally to the respective given surface elements be made. The required system pressure and compressed air consumption for the Suction and re-circulation can be reduced. The surfaces to be sucked off become even and gapless at an optimal energy use for the purpose of fluidizing with compressed air applied.
Nachfolgend soll die Einrichtung anhand eines Ausführungsbeispieles näher erläutert werden. In der Zeichnung zeigt die dort dargestellte einzige Figur diefollowing the device should be explained in more detail using an exemplary embodiment. In the drawing shows the single figure shown there
