Description
Abschirmungseinrichtung bei Elektronenbestrahlungsvorgängen von BahnmaterialienShielding device for electron irradiation processes of web materials
Die Erfindung betrifft eine Einrichtung zur Abschirmung von schädlichen Strahlen, insbesondere von Röntgenstrahlungen bei der Elektronenbestrahlung von Bahnmaterialien.The invention relates to a device for shielding against harmful radiation, in particular X-rays during electron irradiation of web materials.
Die Einrichtung ist besonders fur die Anwendung bei der Elektronenstrahlhärtung von Druckfarben in Druckmaschinen geeignet.The device is particularly suitable for use in electron beam curing of printing inks in printing machines.
In dem DE-GM 93 06 590 wird eine Einrichtung zur Abschirmung von schädlichen Strahlen beschrieben, bei der Kanalabschirmeinrichtungen zwischen einer Bearbeitungsstation und einer Elektronenbestrahlungseinrichtung sowie zwischen der Elektronenbestrahlungseinrichtung und einer nachfolgenden Bahnzugeinrichtung angeordnet sind.DE-GM 93 06 590 describes a device for shielding against harmful radiation, in which channel shielding devices are arranged between a processing station and an electron irradiation device and between the electron irradiation device and a subsequent web pulling device.
Die Kanalabschirmeinrichtung zwischen der Bearbeitungsstation und der Elektronenbestrahlungseinrichtung ist dabei über einen Abklappmechanismus wegklappbar und bietet dadurch erforderlichenfalls den Raum für die Anordnung eines zusätzlichen Trockners wie beispielsweise eines Infrarot- oder UV-Trockners. Weiterhin wird durch diesen Abklappmechanismus die Zugänglichkeit für Arbeiten an der Bearbeitungsstation erhöht.The channel shielding device between the processing station and the electron irradiation device can be folded away using a folding mechanism and therefore provides space for the installation of an additional dryer, if required, such as an infrared or UV dryer. Furthermore, this folding mechanism increases accessibility for work on the processing station.
Nachteilig an dem Abklappmechanismus ist jedoch die erforderliche manuelle Tätigkeit von bis zu zwei Bedienpersonen infolge des hohen Gewichtes der Abschirmmaterialien.A disadvantage of the folding mechanism, however, is the required manual work of up to two operators due to the high weight of the shielding materials.
Zudem besteht keine objektive Übersicht am zentralen Bedienerpult der Maschine über den aktuellen Lagezustand des Abklappmechanismus.In addition, there is no objective overview of the current position of the folding mechanism on the central control panel of the machine.
Die Aufgabe der Erfindung besteht deshalb in der Schaffung einer Abschirmeinrichtung, die den Abklapp Vorgang ferngesteuert und zentral sowie unter einer objektiven Lagekontrolle ermöglicht.The object of the invention is therefore to create a shielding device which enables the folding process to be carried out remotely and centrally as well as with objective position control.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale der Ansprüche.This task is solved by the characterizing features of the claims.
Nachfolgend soll die Erfindung anhand eines Ausführungsbeispieles näher erläutert werden.The invention will be explained in more detail below using an embodiment.
In der abgebildeten einzigen Figur der Zeichnung wird die schematische Anordnung der erfindungsgemäßen Abschirmeinrichtung an einer Druckmaschine mit einer Elektronenstrahlhärtungseinrichtung dargestellt.The single figure shown in the drawing shows the schematic arrangement of the shielding device according to the invention on a printing machine with an electron beam hardening device.
In den Austrittsbereich der bedruckten Papierbahn aus der Druckmaschine im letzte Druckwerk 1 wird der Abschirmkanal 2 mit seinem schwenkbaren Teil 3 durch den Pneumatikzylinder 4 geschwenkt. Dies geschieht durch die Zufuhr von Druckluft über die elektromagnetischen Druckventile 5 und 6. Die jeweils aktuelle Lage dieses schwenkbaren Teiles 3 wird durch die Sensoren 7 und 8 erfasst. So erfasst der Sensor 7 die Lage im heruntergeklapptem Zustand durch die Erfassung der Vorderkante mittels eines Näherungsinitiators.In the exit area of the printed paper web from the printing machine in the last printing unit 1, the shielding channel 2 with its pivoting part 3 is pivoted by the pneumatic cylinder 4. This is done by supplying compressed air via the electromagnetic pressure valves 5 and 6. The current position of this pivoting part 3 is detected by the sensors 7 and 8. The sensor 7 detects the position in the folded-down state by detecting the front edge using a proximity sensor.
• ····
Ist der schwenkbare Teil des Abschirmkanales 3 in den Bereich des Druckwerkes 1 geschwenkt, so wird diese Stellung durch den als Näherungsinitiators ausgebildeten Sensor 8 erfaßt und signalisiert.If the pivotable part of the shielding channel 3 is pivoted into the area of the printing unit 1, this position is detected and signaled by the sensor 8 designed as a proximity sensor.
Die Steuereinrichtung 9 ist in dem an der Druckmaschine vorhandenem zentralen Bediensteuerpult untergebracht und ermöglicht die Steuerung des Pneumatikzylinders 4 über die an sich bekannten elektromagnetischen Druckventile 5 und 6.The control device 9 is housed in the central control panel on the printing machine and enables the control of the pneumatic cylinder 4 via the known electromagnetic pressure valves 5 and 6.
Angezeigt wird die vorhandene Stellung des schwenkbaren Teiles des Abschirmkanales 3 mittels der Anzeigeeinrichtung 10. Sie zeigt an, in welche Schwenkrichtung die Bewegung erfolgt und wie groß die Entfernung vom Näherungsinitiator innerhalb dessen Erfassungsbereiches ist.The current position of the pivoting part of the shielding channel 3 is displayed by means of the display device 10. It shows in which pivoting direction the movement occurs and how far the distance from the proximity sensor is within its detection range.
Hat der schwenkbare Teil des Abschirmkanales 3 die Endstellung des hochgeklappten Zustandes noch nicht erreicht, ist durch die Anwendung einer elektronischen Funktionssperre die Inbetriebnahme der Druckmaschine verhindert.If the pivoting part of the shielding channel 3 has not yet reached the end position of the folded-up state, the start-up of the printing machine is prevented by the use of an electronic function lock.
Beschädigungen der Druckmaschine und Entstehung von Makulatur werden so verhindert.This prevents damage to the printing press and the creation of waste paper.
