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 angeordneten 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. Ein weiterer Vorteil ist darin begründet, daß jede Greiferaufschlagleiste einzeln vestellbar ist. Damit können Ungenauigkeiten (bei der Bogenübergabe/Bogenübernahme) auch während des Druckbetriebes korrigiert (manuell oder vom Leitstand aus) werden. Weiterhin stellt die Erfindung eine wirtschaftliche, automatisierbare Lösung dar. Die Einbaulage des Antriebes im Trommelzapfen ist platzsparend, wobei der Antrieb durch einen Elektromotor oder einen Pneumatik- oder Hydraulikantrieb erfolgt.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. Another advantage is in it justifies that each gripper bar can be adjusted individually. This can cause inaccuracies (when transferring / accepting sheets) also corrected during printing (manually or from Control center). Furthermore, the invention provides an economical, automatable solution. The installation position of the The drive in the drum journal is space-saving, the drive by an electric motor or a pneumatic or hydraulic drive he follows.

Eine bogenführende Trommel 2 ist in einer Offset-Rotationsdruckmaschine
einem Druckzylinder des vorhergehenden Druckwerkes nachgeordnet
und der Trommel 2 ist ein Druckzylinder eines weiteren
Druckwerkes nachgeordnet. Die Trommel 2 ist, bezogen auf einen
einfachen Druckzylinder, mit einem zweifachgroßen Durchmesser
ausgeführt und trägt somit zwei Greiferbrücken 23. Am Umfang der
Trommel 2 sind die beiden Greiferbrücken 23 symmetrisch verteilt
angeordnet (180° versetzt). Jede Greiferbrücke 23 besteht aus einer
Greiferwelle 19, Greifern 20 und in annähernd radialer Richtung
einstellbaren Greiferaufschlagleisten 18. Die Greiferaufschlagleiste
18 trägt für jeden Greifer 20 zugeordnete Auflageklötzchen
für die Einzelgreiferauflage.A sheet-guiding
Die Trommel 2 ist mit beiden Trommelzapfen 4 drehbar in jeweils
einer Lagerung 3 eines Seitengestelles 1 aufgenommen. Jeder Greiferaufschlagleiste
18 ist eine Positioniereinrichtung zugeordnet,
die abhängig von der Bedruckstoffstärke das Hoch- oder Tiefstellen
der Greiferaufschlagleiste 18 bewirkt. Die Postioniereinrichtung
ist axial beweglich am Trommelkörper 2 gelagert. Bei einer zweifachgroßen
Trommel 2 sind somit zwei Postioniereinrichtungen angeordnet,
die jeweils durch eine Postionierstange 16 und mehreren
daran befestigten keilförmigen Elementen 17 gebildet sind. Die
keilförmigen Elemente 17 einer Positioniereinrichtung sind mehreren
keilförmigen Elementen der Greiferaufschlagleiste 18 zugeordnet.
Die keilförmigen Elemente 17 sowie die keilförmigen Elemente der
Greiferaufschlagleiste 18 bilden je ein Gleitgelenk in Form eines
Schubkeils. Jedes an der Positionierstange 16 angeordnete keilförmige
Element 17 wirkt dabei als Antriebsglied, jedes keilförmige
Element der Greiferaufschlagleiste 18 wirkt als Abtriebsglied. Die
Greiferaufschlagleiste 18 ist federbelastet gegen die Positioniereinrichtung
abgestützt. Die Trommel 2 besitzt an einer Seite in
ihrem Trommelzapfen 4 einen Antrieb 5, der mit dem Seitengestell 1
über eine Halterung 6 fixiert ist. Der Antrieb 5 besitzt eine
Antriebswelle 7, die mit einer Geradführung 8, 9 ein Schraubengetriebe
bildet. Auf dem Umfang der Geradführung 8, 9 ist ein Ring
10 drehbar gelagert, der pro zu verstellender Greiferaufschlagleiste
18 über ein Drehgelenk 11 mit einer Zahnstange 13 gekoppelt
ist. Jede Zahnstange 13 weist ein Zahnsegment 22 auf, das mit einer
Außenverzahnung eines Stellmittels 15, z.B. einer drehbar gelagerten
Stellwelle, in Eingriff bringbar ist. Mittels Stellringen 14
ist jede Zahnstange 13 an dem betreffenden Stellmittel 15 geführt.
Jedes Stellmittel 15 ist im Bereich der Achse der Trommel 2 drehbar
gelagert. Antriebswelle 7, Geradführung 8, 9, Ring 10, Drehgelenk
11, Zahnstange 13 und die Außenverzahnung des Stellmittels 15
bilden eine getriebetechnische Kopplung 12.The
Im vorliegenden Beispiel einer zweifachgroßen Trommel 2 sind auf
dem Ring 10 zwei Zahnstangen 13 (180° versetzt) über je ein Drehgelenk
11 gekoppelt. Die Zahnstangen 13 besitzen versetzt auf der
Zahnstange 13 angeordnete Zahnsegmente 22, so daß stets nur eine
Zahnstange 13 mit einem Stellmittel 15 in Eingriff steht.In the present example a double-sized
Bei einer dreifachgroßen Trommel 2 sind drei Stellmittel 15 um 120°
versetzt angeordnet, denen drei Zahnstangen 13 zugeordnet sind.
Die Zahnstangen 13 weisen Zahnsegmente 22 auf, die so angeordnet
sind, daß stets nur eine Zahnstange 13 mit dem Stellmittel 15 in
Eingriff steht. With a triple-sized
Bei einer vierfachgroßen Trommel 2 sind vier Stellmittel 15 um 90° versetzt
angeordnet, denen vier Zahnstangen 13 zugeordnet sind. Die Zahnstangen 13
weisen ebenfalls Zahnsegmente 22 auf, die so angeordnet sind, daß stets nur ein
Zahnsegment 13 mit dem Stellmittel 15 in Engriff steht.In the case of a
Die Wirkungsweise ist wie folgt:The mode of action is as follows:
Die Trommel 2 übernimmt einen bedruckten Bogen von einem Druckzylinder eines
vorgeordneten Druckwerkes und übergibt den Boden an den Druckzylinder des
nachgeordneten Druckwerkes. Soll ein Bedruckstoff mit veränderter Dicke (Stärke)
verarbeitet werden, ist es erforderlich die Greiferaufschlagleiste 18 höher oder tiefer
einzustellen. Der Antrieb 5 wird manuell oder automatisch, z.B. von einem Leitstand
aus aktiviert. Der Antrieb 5 setzt die Antriebswelle 7 in Bewegung. Antriebswelle 7
und Geradführung 8, 9 bilden ein Schraubengetriebe, so daß Antriebswelle 7 als
Antriebsglied und Geradführung 8, 9 als Abtriebsglied wirken. Die Geradführung 8, 9
führt axial eine Relativbewegung aus, welche den Ring 10 mitbewegt. Der Ring 10
überträgt die Bewegung in Bewegungsrichtung 21 über die Zahnstange 13 auf das
drehbare Stellmittel 15, welches die Positionierstange 16 axial betätigt und die
zugeordnete Greiferaufschlagleiste 18 verstellt. Die Zahnstange 13 besitzt ein
Zahnsegment 22, welches nur in einem definierten Bereich mit der Außenverzahnung
des Stellmittels 15 in Eingriff ist. Wird der
Bereich verlassen, so ist das Zahnsegment 22 mit dem Stellmittel 15
außer Eingriff, d.h. das Stellmittel 15 bleibt in seiner Position
fixiert.The
Besitzt die Trommel 2 zwei Greiferaufschlagleisten 18, so wird
jedes Stellmittel 15 separat nacheinander von einer Zahnstange 13
gedreht. Ist die erste Zahnstange 13 mit der ersten Stellwelle 15
in Eingriff, so ist die zweite Zahnstange 13 mit der zweiten
Stellwelle 15 außer Eingriff und umgekehrt. Dies gestattet eine
individuelle, separate Einstellung jeder Greiferaufschlagleiste 18.
Bei drei und vier Greiferaufschlagleisten 18 erfolgt die Verstellung
analog. Es ist stets nur ein Zahnsegment 22 einer Zahnstange
13 mit dem entsprechenden Stellmittel 15 in Eingriff. If the
