Gemäß der DE 3 428 668 C2 ist eine zentrale Greiferaufschlagleistenverstellung für zwei- und mehrfachgroße Umführtrommeln bekannt. An die Greiferauflagen angreifende Mittel gestatten die Einzeljustage jeder Auflage und auf diese Mittel wirken insgesamt die Greiferauflagen verstellende Positioniermittel ein, die von einer zentralen Stellvorrichtung betätigt werden. Die zentrale Stellvorrichtung kann dabei motorisch angetrieben und von einem Steuerpult aus gesteuert werden. Hinweise, wie der Antrieb mit der Stellvorrichtung zu koppeln ist, sind nicht zu entnehmen.According to DE 3 428 668 C2 there is a central gripper turn bar adjustment for two and multiple sized transfer drums known. Means attacking the gripper pads allow Individual adjustment of each edition and on these means act overall a positioning means adjusting the gripper pads, by be operated by a central adjusting device.

Aus der GB 2 098 966 A ist eine Einrichtung zum Positionieren
(Hoch- und Tiefstellen) der Greiferauflage einer Greiferbrücke
eines Bogenführungszylinders bekannt. Das Positionieren der Greiferauflagen,
je nach Dicke des zu verarbeitenden Bedruckstoffes,
erfolgt mittels Einstellstange, die in Zylinderachsrichtung gegen
Federkraft mittels einer Schraube verschiebbar unter einer über die
gesamte Zylinderlänge verlaufenden Greiferauflage angeordnet ist.
Die Kontaktflächen von Greiferauflage und Einstellstangen bilden in
Zylinderachsrichtung ein Schubkeilgetriebe, derart, daß eine
Verschiebung der Einstellstange die radiale Positionierung der
Greiferauflagen (höher oder tiefer stellen) bewirkt.
Nachteilig ist, daß zum zentralen Einstellen der Greiferaufschlagleisten auf die jeweilige Bedruckstoffstärke ein hoher Aufwand erforderlich ist. Bei Umführtrommeln mit mehreren Greiferbrücken nach DE 3 428 668 C2 ist eine Grund- und Feinjustierung der Greiferaufschlagleisten erforderlich um eine genaue Verstellung aller Greiferaufschlagleisten zu ermöglichen. Danach ist eine separate Verstellung der Greiferaufschlagleisten, beispielsweise um Ungenauigkeiten bei der Bogenübernahme oder Bogenübergabe zwischen bogenführenden Zylindern zu vermeiden oder bei einer unbeabsichtigten Greiferaufschlagleistenverstellung, nicht möglich. Eine individuelle Verstellung jeder Greiferaufschlagleiste ist nur durch Lösen der arretierten Justiermittel manuell möglich.The disadvantage is that for the central adjustment of the gripper bars a lot of effort for the respective substrate thickness is required. For transfer drums with multiple gripper bars according to DE 3 428 668 C2 is a basic and fine adjustment of the gripper bar required for a precise adjustment of all To enable gripper slats. After that is a separate one Adjustment of the gripper bars, for example by inaccuracies when taking over or handing over the sheet between to avoid arc-guiding cylinders or in the event of an accidental Gripper turn bar adjustment, not possible. A individual adjustment of each gripper bar is only possible through The locked adjustment means can be released manually.
Aufgabe der Erfindung ist es, eine separate Verstellung (hoch bzw. tief stellen) aller Greiferbrücken der bogenführenden Trommel auf die zu verarbeitende Bedruckstoffstärke vorzunehmen und mögliche Ungenauigkeiten bei der Bogenübernahme/Bogenübergabe auszugleichen.The object of the invention is a separate adjustment (high or lower) of all gripper bars of the sheet-guiding drum to carry out the printing stock thickness to be processed and possible Compensate for inaccuracies in the sheet transfer / sheet transfer.
Gelöst wird das durch den kennzeichnenden Teil des Hauptanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen.This is solved by the characterizing part of the main claim. Further training results from the subclaims.
Die erfindungsgemäße Lösung ist vorwiegend für bogenführende Trommeln (Umführtrommeln) geeignet, sie ist darüberhinaus auch auf bogenführende Zylinder anwendbar und eignet sich somit auch zur Greiferaufschlagleistenverstellung bei Anlegetrommeln oder Vorgreiferzylindern. Die vorliegende Erfindung eignet sich insbesondere für ein- bis vierfachgroße Trommeln (bezogen auf einen einfachgroßen Druckzylinder) mit der entsprechenden Anzahl von symmetrisch am Umfang angeordnete Greiferbrücken. Sie dient der Verarbeitung von Bedruckstoffen mit unterschiedlicher Stärke, wie z.B. Papier oder Karton. Die separate Verstellung der Greiferauflagen einer bogenführenden Trommel verkürzt die Umstellzeit und minimiert subjektive Einflüsse und eliminiert Ungenauigkeiten bei der Bogenübergabe bzw. Bogenübernahme. Weiterhin stellt die Erfindung eine wirtschaftliche, automatisierbare Lösung dar. Die Einbaulage der Betätigungseinrichtung ist fluchtend mit der Positioniereinrichtung am Trommelkörper, derart, daß keine Kollision mit den benachbarten Seitengestellen eintritt. Jede Betätigungseinrichtung wird separat von der jeweiligen Energieversorgung, insbesondere in Folge, angesteuert.The solution according to the invention is primarily for sheet-guiding Drums (transfer drums) suitable, it is also open bow-guiding cylinder applicable and is therefore also suitable for Adjustment of the gripper bar for feed drums or pre-gripper cylinders. The present invention is particularly suitable for one to four times the size of drums (based on a single size Impression cylinder) with the corresponding number of symmetrical Gripper bridges arranged on the circumference. It is used for processing of substrates with different thickness, e.g. Paper or cardboard. The separate adjustment of the gripper pads A sheet-guiding drum shortens the changeover time and minimizes it subjective influences and eliminates inaccuracies in the sheet transfer or sheet acceptance.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigen:
- Fig. 1
- die Erfindung bei einer doppeltgroßen Trommel (Vorderansicht).
- Fig. 1
- the invention in a double-sized drum (front view).
Eine bogenführende Trommel 1 ist in einer Offset-Rotationsdruckmaschine
einem Druckzylinder des vorhergehenden Druckwerkes nachgeordnet
und der Trommel 1 ist ein Druckzylinder eines weiteren
Druckwerkes nachgeordnet. Die Trommel 1 ist, bezogen auf einen
einfachen Druckzylinder, mit einem zweifachgroßen Durchmesser
ausgeführt und trägt somit zwei Greiferbrücken 12. Am Umfang der
Trommel 1 sind die beiden Greiferbrücken 12 symmetrisch verteilt
angeordnet (180° versetzt). Jede Greiferbrücke 12 besteht aus einer
Greiferwelle, Greifern und in annähernd radialer Richtung einstellbaren
Greiferaufschlagleisten 2. Die Greiferaufschlagleiste 2
trägt für jeden Greifer zugeordnete Auflageklötzchen für die
Einzelgreiferauflage.A sheet-guiding drum 1 is in an offset rotary printing machine
downstream of a printing cylinder of the previous printing unit
and the drum 1 is a printing cylinder of another
Subordinate printing unit. The drum 1 is based on one
simple impression cylinder, with a double-sized diameter
executed and thus carries two
Die Trommel 1 ist mit beiden Trommelzapfen drehbar in jeweils einer
Lagerung eines Seitengestelles 11 aufgenommen. Jeder Greiferaufschlagleiste
2 ist eine Positioniereinrichtung 3 zugeordnet, die
abhängig von der Bedruckstoffstärke das Hoch- oder Tiefstellen der
Greiferaufschlagleiste 2 bewirkt. Die Positioniereinrichtung 3 ist
axial beweglich am Trommelkörper 1 gelagert. Bei einer zweifachgroßen
Trommel 1 sind somit zwei Positioniereinrichtungen 3 angeordnet,
die jeweils durch eine Positionierstange 4 und mehrere daran
befestigte keilförmige Elemente 5 gebildet sind. Die keilförmigen
Elemente 5 einer Positioniereinrichtung 3 sind mehreren keilförmigen
Elementen der Greiferaufschlagleiste 2 zugeordnet. Die
keilförmigen Elemente 5 sowie die keilförmigen Elemente der
Greiferaufschlagleiste 2 bilden je ein Gleitgelenk in Form eines
Schubkeils. Jedes an der Positionierstange 4 angeordnete keilförmige
Element 5 wirkt dabei als Antriebsglied, jedes keilförmige Element
der Greiferaufschlagleiste 2 wirkt als Abtriebsglied. Die Greiferaufschlagleiste
2 ist federbelastet gegen die Positioniereinrichtung
3 abgestützt. An einem freien Ende jeder Positioniereinrichtung
3 ist eine Betätigungseinrichtung 7, im vorliegenden Beispiel
ein Pneumatikzylinder, am Trommelkörper 1 angeordnet. Die Betätigungseinrichtung
7 ist mit der Positionierstange 4 gekoppelt und
ist über ein Leitungssystem 8 mit einem am Trommelzapfen angeordneten
Drehübertrager 9 verbunden. Der Drehübertrager 9 ist mit eine
Energieversorgung 10 verbunden, die jede Betätigungseinrichtung 7
separat steuert. Bei Verwendung von Pneumatikzylindern erfolgt die
gesteuerte Druckluftzufuhr über einen Ventilblock. Jede Positioniereinrichtung
3 ist in ihrem axialen Hub durch justierbare
Anschläge 6 begrenzt. Dadurch läßt sich durch die Positioniereinrichtung
3 jede Greiferaufschlagleiste 2 in zwei Stufen verstellbar
betreiben. Die erste Stufe (Hochstellen der Greiferaufschlagleiste
2) ist für Papier geeignet. Die zweite Stufe (Tiefstellen
der Greiferaufschlagleiste 2) ist für Karton geeignet.The drum 1 is rotatable with two drum pins in one
Storage of a
Die Wirkungsweise ist wie folgt:
Die Trommel 1 übernimmt einen bedruckten Bogen von einem Druckzylinder
eines vorgeordneten Druckwerkes und übergibt den Bogen an
den Druckzylinder des nachgeordneten Druckwerkes. Soll ein Bedruckstoff
mit veränderter Dicke (Stärke) verarbeitet werden, ist
es erforderlich die Greiferaufschlagleiste 2 höher oder tiefer
einzustellen. Die Energieversorgung 10 wird manuell oder automatisch,
z.B. von einem Leitstand aus aktiviert. Jede Betätigungseinrichtung
7, hier der Pneumatikzylinder, wird mit Druckluft
einzeln in Folge an der betreffenden Greiferbrücke 12 angesteuert.
Dies bewirkt, daß der Kolben des Pneumatikzylinders die gekoppelte
Positionierstange 4 axial bis zum Anschlag bewegt (erste Stufe).
Die axiale Bewegung der Positionierstange 4 bewirkt die radiale
Verstellung der Greiferaufschlagleiste 2 innerhalb von zwei Stufen.
Die umgekehrte Ansteuerung der Betätigungseinrichtung 7, im
vorliegenden Fall ist dies ein doppeltwirkender Pneumatikzylinder,
bewegt den Kolben und damit die Positioniereinrichtung 3 in entgegengesetzte
Richtung. Dies bewirkt wiederum die Verstellung der
Greiferaufschlagleiste 2 gegen den entsprechenden Anschlag in die
zweite Stufe. Es hat sich in der Druckpraxis die Verstellung in
zwei Stufen als ausreichend herausgestellt. So ist z.B. ein Abstand
der Oberkanten der Greiferaufschlagleisten einer Trommel 1 zum
benachbarten Druckzylinder bei Papier von ca. 0,2mm und bei Karton
von ca. 0,7mm günstig. The mode of action is as follows:
The drum 1 accepts a printed sheet from a printing cylinder of an upstream printing unit and transfers the sheet to the printing cylinder of the downstream printing unit. If a substrate with a changed thickness (thickness) is to be processed, it is necessary to set the
