Abstract
Description
Vorliegende Erfindung betrifft eine Vorrichtung zum Pudern von Druckbogen in einer Druckmaschine, umfassend einen Vorratsbehälter für den Puder, einen Dosierer zum Dosieren des Puders, der an den Vorratsbehälter angeschlossen ist, eine Sprühstange mit Puderdüsen, einen Verteiler zum Verteilen eines Puder-Luft-Gemisches auf die Puderdüsen und eine Verbindungsleitung zwischen dem Dosierer und dem Verteiler.The present invention relates to a device for powdering printed sheets in a printing machine, comprising a reservoir for the powder, a metering device for metering the powder, which is connected to the reservoir, a spray bar with powder nozzles, a distributor for distributing a powder-air mixture the powder nozzles and a connecting line between the doser and the distributor.

Ungünstig an dem beschriebenen Stand der Technik ist, dass bei diesem ein separates Gebläse bzw. ein separater Kompressor erforderlich ist. Dadurch steigen die Herstellungskosten. Außerdem erfordert das separate Gebläse Bauraum, der infolgedessen für andere Einrichtungen fehlt.Unfavorable in the described prior art is that in this a separate blower or a separate compressor is required. This increases the production costs. In addition, the separate fan requires space, which consequently lacks for other facilities.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute und Bauraum sparende Pudervorrichtung zu schaffen.The invention has for its object to provide a simply constructed and space-saving powder device.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die erfindungsgemäße Vorrichtung zum Pudern von Druckbogen in einer Druckmaschine umfasst einen Vorratsbehälter für den Puder, einen Dosierer zum Dosieren des Puders, der an den Vorratsbehälter angeschlossen ist, eine Sprühstange mit Puderdüsen, einen Verteiler zum Verteilen eines Puder-Luft-Gemisches auf die Puderdüsen und eine Verbindungsleistung zwischen dem Dosierer und dem Verteiler und ist dadurch gekennzeichnet, dass eine Zuführleitung zum Zuführen von Druckluft in die Verbindungsleitung einmündet, dass ein zwischen der Zuführleitung und dem Verteiler liegender Abschnitt der Verbindungsleitung als Mischkammer zum Mischen der Druckluft mit dem Puder angeordnet ist und dass die Zuführleitung an eine zentrale Druckluftversorgung der Druckmaschine angeschlossen ist.This object is achieved by a device having the features of claim 1. The inventive device for powdering printed sheets in a printing press comprises a reservoir for the powder, a metering device for metering the powder, which is connected to the reservoir, a spray bar with powder nozzles, a distributor for distributing a powder-air mixture on the powder nozzles and a connection performance between the doser and the distributor and is characterized in that a supply line for supplying compressed air in the connection line opens, that a lying between the supply line and the manifold portion of the connecting line is arranged as a mixing chamber for mixing the compressed air with the powder and that the supply line is connected to a central compressed air supply of the printing press.
Ein Vorteil der erfindungsgemäßen Pudervorrichtung ist darin zu sehen, dass die Herstellkosten stark reduziert sind. Ein weiterer Vorteil besteht darin, dass durch den Wegfall des separaten Gebläses Bauraum frei wird, der für andere Einrichtungen genutzt werden kann. Ein Zusatzvorteil besteht in funktioneller Hinsicht, weil die zugeführte Druckluft zum Steuern der Dosiermenge genutzt werden kann.An advantage of the powder device according to the invention is the fact that the production costs are greatly reduced. Another advantage is that the elimination of the separate blower space is free, which can be used for other facilities. An additional advantage is in functional terms, because the supplied compressed air can be used to control the dosing.
Es sind verschiedene Weiterbildungen der erfindungsgemäßen Vorrichtung möglich.There are various developments of the device according to the invention possible.
Bei einer Weiterbildung ist der Vorratsbehälter hermetisch oder zumindest quasi-hermetisch verschlossen. Dadurch wird ein Leckageluftstrom aus der Umgebung vermieden.In a further development of the reservoir is hermetically sealed or at least quasi-hermetically sealed. This avoids leakage airflow from the environment.
Bei einer weiteren Weiterbildung ist in die Zuführleitung eine Steuereinrichtung zum Steuern der zugeführten Druckluft integriert. Mit der Steuereinrichtung lässt sich der Durchfluss der Druckluft steuern.In a further development, a control device for controlling the supplied compressed air is integrated into the supply line. With the control device, the flow of compressed air can be controlled.
Bei einer weiteren Weiterbildung versorgt die zentrale Luftversorgung pneumatische Bogenleiteinrichtungen der Druckmaschine mit Druckluft. Die zentrale Druckluftversorgung wird also zum Versorgen sowohl der Pudervorrichtung als auch der pneumatischen Bogenleiteinrichtungen mit Druckluft gleichzeitig verwendet.In a further development, the central air supply supplies pneumatic sheet guiding devices of the printing press with compressed air. The central compressed air supply is thus used simultaneously to supply both the powder device and the pneumatic sheet guiding devices with compressed air.
Weitere konstruktiv und funktionell vorteilhafte Weiterbildungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels und der dazugehörigen Zeichnung.Other constructive and functional advantageous developments of the invention will become apparent from the following description of a preferred embodiment and the accompanying drawings.
