Description

Die Erfindung betrifft eine Bogenleiteinrichtung für einen bogenführenden Druckmaschinenzylinder nach dem Oberbegriff des Hauptanspruches.The invention relates to a sheet guiding device for a sheet-guiding printing press cylinder according to the preamble of the main claim.

Eine Bogenleiteinrichtung dieser Art ist aus der EP 0 306 684 B1 bekannt. Die Einrichtung dient dem flächigen Anpressen eines Bogens auf den Druckzylinder. Nach Durchlaufen einer Druckzone wird der Bogen im Bereich zwischen Druckzone und dem Übergabebereich (Tangentenpunkt) einer nachfolgenden Wendetrommel mittels Blasluft auf dem Druckzylinder geführt.A sheet guiding device of this type is known from EP 0 306 684 B1. The device is used to press a sheet against the impression cylinder. After passing through a printing zone, the sheet is guided in the area between the printing zone and the transfer area (tangent point) of a subsequent turning drum by means of blown air on the printing cylinder.

Eine weitere Bogenleiteinrichtung ist aus der DE 3 608 795 A1 bekannt. Danach ist vor und nach einer Druckzone die Anordnung eines über die Breite des Bogens wirkenden Blasrohres mit Düsen bekannt, die zwischen Bogen und Blasrohr ein Stellelement aufweisen.Another sheet guiding device is known from DE 3 608 795 A1. Thereafter, before and after a pressure zone, the arrangement of a blowpipe acting across the width of the sheet with nozzles is known which have an actuating element between the sheet and blowpipe.

Nachteilig bei diesen Ausführungen ist es, daß die über das Bogenformat hinausreichenden Austrittsöffnungen sich negativ auf die Bogenführung auswirken, indem abhängig vom Format der Bogen durch die Austrittsöffnungen, insbesondere an den Seitenkanten, der Bogen unterblasen wird. Dies führt zu einem unruhigen Bogenlauf und kann zum Abschmieren führen.A disadvantage of these designs is that the outlet openings extending beyond the sheet format have a negative effect on the sheet guidance, since, depending on the format of the sheet, the sheet is blown through the outlet openings, in particular at the side edges. This leads to unsteady sheet travel and can lead to greasing.

Aufgabe der Erfindung ist es, eine abschmierfreie Bogenführung zu entwickeln, die auch das zu verarbeitende Bogenformat berücksichtigt.The object of the invention is to develop a lubrication-free sheet guide which also takes into account the sheet format to be processed.

Gelöst wird dies durch die Ausbildungsmerkmale des Hauptanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen.This is solved by the training features of the main claim. Further training results from the subclaims.

Zwischen zwei Seitengestellen erstreckt sich die Bogenleiteinrichtung, die vor und/oder nach einer Druckzone dem bogenführenden Druckmaschinezylinder zugeordnet ist. Die einzelnen Leitelemente können dabei dicht nebeneinander angeordnet sein oder auch in definierten Abständen sich über die Länge des Zylinders erstrecken.The sheet guiding device, which is assigned to the sheet-guiding printing press cylinder before and / or after a printing zone, extends between two side frames. The Individual guide elements can be arranged close to one another or can also extend at defined intervals over the length of the cylinder.

Erfindungsgemäß werden Leitelemente entsprechend des jeweiligen Bogenformates an den die Formatbreite überschreitenden Leitelementen ab- oder zugeschaltet. Bei kleineren Formaten sind die äußeren pneumatisch beaufschlagbaren Leitelemente abgestellt. Für bestimmte Bedruckstoffe können die Leitelemente auch alternierend zu- bzw. abgeschaltet, auch über das Format hinaus, werden.According to the invention, guide elements are switched on or off in accordance with the respective sheet format on the guide elements which exceed the format width. In the case of smaller formats, the outer pneumatically actuated guide elements are switched off. For certain substrates, the guide elements can also be switched on and off alternately, even beyond the format.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.

In einer Bogenrotationsdruckmaschine für Schön- und Schön- und Widerdruck ist zwischen zwei Druckwerken eine Wendeeinrichtung angeordnet. Das in Bogenlaufrichtung 11 vorgeordnete Druckwerk wird bei einer Offsetdruckmaschine in bekannter Weise durch einen bogenführenden Druckmaschinenzylinder, ein Gummituchzylinder und ein Plattenzylinder gebildet. Auf die Farb- und Feuchtwerksausbildung soll hier nicht weiter eingegangen werden.A turning device is arranged between two printing units in a sheet-fed rotary printing press for perfecting and perfecting. In an offset printing machine, the printing unit arranged upstream in the sheet running direction 11 is formed in a known manner by a sheet-guiding printing press cylinder, a blanket cylinder and a plate cylinder. The ink and dampening system training will not be discussed further here.

Nach einer durch den Druckmaschinenzylinder und Gummituchzylinder gebildeten Druckzone und vor dem durch Druckmaschinenzylinder und nachgeordneter Wendetrommel gebildeten Übergabebereich ist die erfindungsgemäße Bogenleiteinrichtung angeordnet. Für die jeweilige Betriebsart (Schöndruck/Schön- und Widerdruck) ist die Bogenleiteinrichtung zum Druckmaschinenzylinder an- und abschwenkbar angeordnet. Die Bogenleiteinrichtung wird durch eine hohle Blaseinrichtung 3 gebildet, z.B. einem Blasrohr, welche sich über die Lange des Druckmaschinenzylinders erstreckt.The sheet guiding device according to the invention is arranged after a printing zone formed by the printing press cylinder and blanket cylinder and in front of the transfer area formed by the printing press cylinder and downstream turning drum. For the respective operating mode (straight printing / fine and reverse printing), the sheet guiding device can be swiveled in and out of the printing press cylinder. The sheet guiding device is formed by a hollow blowing device 3, e.g. a blow pipe, which extends over the length of the printing press cylinder.

Um einen Bogen 1 auf der Oberfläche des Druckmaschinenzylinders mit Blasluft flächig angepreßt zu führen, besitzt die Blaseinrichtung 3 an die Krümmung des Druckmaschinenzylinders angepaßte hohle Leitelemente 4. Die Leitelemente 4 sind mehrfach nebeneinander, vorzugsweise beabstandet, über die Lange des Druckmaschinenzylinders analog zur Blaseirrichtung 3 an dieser angeordnet. Jedes hohle Leitelement 4 weist an der dem Bogen 1 zugewandten Kontur Austrittsöffnungen 5, z.B. Bohrungen, aufIn order to guide a sheet 1 to the surface of the printing press cylinder with blown air, the blowing device 3 has hollow guide elements 4 which are adapted to the curvature of the printing press cylinder. The guide elements 4 are multiply adjacent to one another, preferably spaced, over the length of the printing press cylinder analogously to Bladder 3 arranged on this. Each hollow guide element 4 has outlet openings 5, for example bores, on the contour facing the arch 1

Weiterhin sind die Leitelemente 4 mit der Blaseinrichtung 3 gekoppelt, indem jeder Hohlraum eines Leitelementes 4 durch eine Durchströmöffnung 6 mit dem Hohlraum der Blaseinheit 3 verbunden ist. Die Blaseinheit 3 weist weiterhin für jedes Leitelement 4 eine ein Verschlußelement 7 tragende Stelleinrichtung 8 auf. Das Verschlußelement 7 ist der Durchströmöffnung 6 zugeordnet. Jede Stelleinrichtung 8 ist mit Signalverbindung 9 versehen, welche mit einer Steuerung 10, z.B. einem Leitstand, gekoppelt ist. Die Blaseinheit 3 ist mit einer Luftversorgung gekoppelt.Furthermore, the guide elements 4 are coupled to the blowing device 3 in that each cavity of a guide element 4 is connected to the cavity of the blowing unit 3 through a throughflow opening 6. The blowing unit 3 also has an adjusting device 8, which carries a closure element 7, for each guide element 4. The closure element 7 is assigned to the flow opening 6. Each actuating device 8 is provided with signal connection 9, which is connected to a controller 10, e.g. a control center. The blowing unit 3 is coupled to an air supply.

Die Wirkungsweise ist wie folgt: Die Blaseinheit 3 wird von der Luftversorgung mit Blasluft beaufschlagt. Diese strömt aus dem Hohlraum der Blaseinheit 3 durch die offenen Durchströmöffungen 6 in den Hohlraum jedes Leitelementes 4 und tritt durch die Austrittsöffnung 5 strömend auf den Bogen 1 auf. Bei Verarbeitung von Bedruckstoff mit unterschiedlichen Bogenformaten, insbesondere bei unterschiedlichen Formatbreiten 2, werden die über die jeweilige Formatbreite 2 hinausreichenden Leitelemente 4 von der Steuerung 10 einzeln verschlossen oder auch geöffnet. Damit wird über die Bogenformatbreite 2 das Zu- bzw. Abschalten der Blasluft an den Austrittsöffnungen 5 gesteuert. Erhält die Stelleinrichtung 8 ein entsprechendes Signal zur Aktivierung, so verschließt zwecks abschalten der Blasluft das Verschlußelement 7 die Durchströmöffnung 6. Soll die Blasluft zugeschaltet werden, so wird von der Steuerung 10 wiederum die Stelleinrichtung 8 aktiviert. Das Verschlußelement 7 öffnet die Durchströmöffnung 6 und gibt somit den Weg für die Blasluft frei, welche aus den Austrittsöffnungen 5 auf den Bogen 1 auftreffen kann. Damit wird die abschmierfreie Bogenführung realisiert. Weiterhin kann das Verschlußelement 7 je nach Positionierung auch die Durchströmöffnung 6 in ihrem Öffnungsgrad variabel gestalten, so daß die Menge an Blasluft geregelt wird. Das Abschalten der Blasluftzuführ bei den über die Formatbreite 2 hinausreichenden Leitelementen 4 führt zu einer ruhigen Bogenführung auf dem Druckmaschinenzylinder, da das Unterblasen der Bogen 1 entfällt und zum besseren Anpressen des Bogens 1 auf den Druckzylinder durch die Kraftwirkung der ausströmenden Blasluft.The mode of operation is as follows: The blower unit 3 is supplied with blown air by the air supply. This flows out of the cavity of the blowing unit 3 through the open through-flow openings 6 into the cavity of each guide element 4 and flows through the outlet opening 5 onto the sheet 1. When processing printing material with different sheet formats, in particular with different format widths 2, the control elements 4, which extend beyond the respective format width 2, are individually closed or also opened by the controller 10. The switching on and off of the blown air at the outlet openings 5 is thus controlled via the sheet format width 2. If the actuating device 8 receives a corresponding signal for activation, the closure element 7 closes the flow-through opening 6 for the purpose of switching off the blown air. The closure element 7 opens the throughflow opening 6 and thus clears the way for the blown air, which can strike the sheet 1 from the outlet openings 5. With this, the lubrication-free sheet guidance is realized. Furthermore, depending on the positioning, the closure element 7 can also make the opening 6 variable in its degree of opening, so that the amount of blown air is regulated. Switching off the blown air supply for the guide elements 4 extending beyond the format width 2 leads to a smooth sheet guidance on the printing press cylinder, since there is no need to blow the sheet 1 and the sheet 1 is better pressed against the impression cylinder by the force of the blowing air flowing out.
