Ein antreibbares Bogenhaltesystem dieser Art ist aus DE 43 39 388 C2 bekannt. An einer Greiferwelle ist ein Greiferwellenhebel angeordnet, der am Ende eine Kurvenrolle trägt. Die von einer Zugfeder kraftschlüssig belastete Kurvenrolle ist mit einer Kurvenbahn gepaart. Dabei ist die Kurvenbahn innerhalb eines Rollenhebels endseitig integriert und die Kurvenrolle ragt in den Rollenhebel zwecks Bildung eines Kurvengetriebes in die Kurvenbahn hinein. Der Rollenhebel weist einen Drehpunkt auf und trägt am von der Kurvenbahn abgewandten Ende weiterhin eine Rolle, welche mit einer Steuerkurve gepaart ist. Zusätzlich ist der Rollenhebel mit einer Druckfeder in Funktionsverbindung, welche die Rolle kraftschlüssig auf der Steuerkurve führt.A drivable bow support system of this type is out DE 43 39 388 C2 known. There is a gripper shaft lever on a gripper shaft arranged at the end of a cam roller wearing. The cam roller frictionally loaded by a tension spring is paired with a cam track. Here is the Cam track integrated at the end within a roller lever and the cam roller protrudes into the roller lever for formation a cam mechanism into the cam track. The roller lever has a fulcrum and carries on from the cam track opposite end continues to play a role with a Control curve is paired. The roller lever is also included a compression spring in functional connection, which the role leads non-positively on the control curve.
Aus DE 197 52 550 A1 ist ein weiterer Antrieb für ein Bogenhaltesystem bekannt. Hierbei ist zur Antriebssteuerung der Greifer ein Greifersteuergetriebe, gebildet durch einen Winkelhebel, eine Koppel und einen Greiferwellenantriebshebel, sowie ein Vorschaltgetriebe, gebildet aus einer Steuerkurve, einer Kurvenrolle, einem Rollenhebel und einer weiteren Koppel, vorgesehen. Der Rollenhebel und die weitere Koppel bilden einen Zweischlag, der so ausgelegt ist, dass bei geschlossenen überdrückten Greifern dieser Zweischlag nahe einer Kniehebelstellung steht.

Another drive for a sheet holding system is known from DE 197 52 550 A1 known. Here is the drive control Gripper a gripper control gear, formed by a Angle lever, a coupling and a gripper shaft drive lever, as well as a primary gear, formed from a control cam, a cam roller, a roller lever and another Paddock, provided.

Der Erfindung liegt die Aufgabe zugrunde, ein antreibbares Bogenhaltesystem der eingangs beschriebenen Art zu schaffen, dass die genannten Nachteile vermeidet, dass insbesondere eine Reduzierung der Anzahl der Getriebeglieder gestattet und eine kraftarme Öffnungs- und Schließbewegung des Bogenhaltesystemes erlaubt.The invention has for its object a drivable To create a bow holding system of the type described at the outset, that avoids the disadvantages mentioned, in particular allows a reduction in the number of transmission links and a low-force opening and closing movement of the sheet holding system allowed.
Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale
der Ansprüche 1 und 2 gelöst. Weiterbildungen
ergeben sich aus den Unteransprüchen.According to the invention, the task is based on the training features
of
Ein erster Vorteil ist darin begründet, dass an einem Bogenführungszylinder mit wenigstens einem Bogenhaltesystem an einer schwenkbaren Greiferwelle ein Kurventräger fixiert ist, welcher mit einem an einem schwenkbaren Hebel angeordneten Eingriffsglied, z.B. ein Gleitsegment, in Funktionsverbindung ist und somit ein Kurvengelenk bildet. Bevorzugt ist der Hebel ein Rollenhebel und das Eingriffsglied ist eine am Rollenhebel gelagerte Rolle. Der Kurventräger ist bevorzugt mittels einer in der Greiferwelle angeordneten Torsionsfeder federbelastet mit dem Eingriffsglied bzw. der Rolle gepaart.A first advantage is based on the fact that a sheet guide cylinder with at least one sheet holding system a cam carrier is fixed to a swiveling gripper shaft, which is arranged with a pivotable lever Engaging member, e.g. a sliding segment, in functional connection is and thus forms a curve joint. The is preferred Lever a roller lever and the engaging member is one on Roller lever mounted roller. The curve bearer is preferred by means of a torsion spring arranged in the gripper shaft spring-loaded paired with the engagement member or the role.
Die Ausbildung des Antriebes des Bogenhaltesystems mittels Kurvengelenk hat u.a. den Vorteil, dass die Getriebeglieder Kurventräger und Eingriffsglied bzw. Rolle an der Paarungsstelle leicht trennbar sind. Beispielsweise ist es bei der Montage bzw. Demontage des Bogenhaltesystems vorteilhaft, dass die Greiferwelle mit daran fixiertem Kurventräger leicht austauschbar ist, während die Antriebssteuerung (Eingriffsglied/Rolle, Rollenhebel, Drehgelenk etc.) am Bogenführungszylinder verbleibt. Alternativ ist auch lediglich der Kurventräger von der Greiferwelle trennbar. The formation of the drive of the sheet holding system by means of The curve joint has the advantage that the transmission links Curve bearer and intervention member or role at the mating point are easily separable. For example, it is with the Assembly or disassembly of the sheet holding system advantageous, that the gripper shaft with attached cam carrier is easy is interchangeable, while the drive control (engagement member / roller, Roller lever, swivel etc.) on the sheet guide cylinder remains. The only other alternative is the person who is responsible for the curve separable from the gripper shaft.
Der Kurventräger zeigt bevorzugt einen annähernd in Richtung der Achse des Bogenführungszylinders zeigenden Kurvenast auf, welcher kraftschlüssig mit dem Eingriffsglied/der Rolle verbunden ist.The curve carrier preferably points approximately in the direction on the curve branch pointing the axis of the curved guide cylinder, which is non-positively with the engagement member / role connected is.
Vorteilhaft ist ebenso, dass bei dem Antrieb des Bogenhaltesystems zumindest durch Ausbildung der Paarungsstelle als Kurvengelenk das Gelenkspiel reduziert ist und somit die Getriebesteifigkeit erhöht ist.It is also advantageous that when the sheet holding system is driven at least by training the mating center as The joint play is reduced and thus the curve joint Gearbox rigidity is increased.
Ein weiterer Vorteil besteht darin, dass der Kurventräger wenig Bauraum benötigt. Damit ist das antreibbare Bogenhaltesystem universell an einfach- oder mehrfachgroßen (bezogen auf einen einfachgroßen Plattenzylinder) Bogenführungszylindern einsetzbar.Another advantage is that the curve bearer little space required. This is the drivable bow holding system universal for single or multiple sizes (related on a simple-sized plate cylinder) sheet guiding cylinders used.
In vorteilhafter Weise sind die in der Paarungsstelle von Kurventräger und Eingriffsglied/Rolle des Bogenhaltesystems auftretenden Kräfte gering. Dies ist bei Einsatz des antreibbaren Bogenhaltesystems in einem als Wendetrommel ausgebildeten Bogenführungszylinder besonders vorteilhaft, da auch die auf eine der Greiferwelle zugeordnete Schwenkwelle der Wendetrommel rückwirkenden Kräfte reduziert sind.Advantageously, those in the mating point of Cam bearer and engaging member / role of the bow support system forces occurring low. This is when using the drivable Sheet holding system in a designed as a turning drum Sheet guiding cylinder is particularly advantageous because the on a swivel shaft of the turning drum assigned to the gripper shaft retroactive forces are reduced.
Schließlich ist es von Vorteil, dass das antreibbare Bogenhaltesystem neben herkömmlichen Bogenführungszylindern (Anlagetrommeln, Transfer- oder Druckzylindern) auch in Wendetrommeln einsetzbar ist, die wahlweise im Schöndruck oder Schönund Widerdruck einsetzbar sind und in denen ein Bogen nach dem Prinzip der Hinterkantenwendung gewendet wird. Derartige Wendetrommeln weisen innerhalb einer Bogenhalteeinheit mehrere antreibbare Bogenhaltesysteme auf. Das erfindungsgemäß antreibbare Bogenhaltesystem kann dabei im Schön- und Widerdruck mit einem Saugersystem oder mit einem weiteren erfindungsgemäß antreibbaren Bogenhaltesystem oder mit einem weiteren erfindungsgemäß antreibbaren Bogenhaltesystem und einem Saugersystem zusammenwirken.Finally, it is advantageous that the drivable bow support system in addition to conventional sheet guiding cylinders (contact drums, Transfer or printing cylinders) also in turning drums can be used, which can either be face-to-face or beautiful Back pressure can be used and in which a bow after the principle of trailing edge turning is applied. such Turning drums have several within one sheet holding unit drivable bow support systems. The invention drivable sheet holding system can be used in perfecting with a suction system or with another according to the invention drivable bow support system or with a further bow holding system which can be driven according to the invention and interact with a suction system.
