[Aufgabe der Erfindung]OBJECT OF THE INVENTION

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 von Haupt- und Nebenanspruch gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, the task is based on the training features resolved from main and secondary claim. Training result from the subclaims.

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 applicable.

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 Schön- und 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 be in plain or fine and 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.

In einer weiteren Ausbildung (Fig. 1) weist das antreibbare Bogenhaltesystem ein Vorschaltgetriebe auf. Dies ist beispielsweise von Vorteil, wenn ungünstige Platzverhältnisse und/oder ungünstige Kräfteverhältnisse am Bogenhaltesystem vorliegen. Das Bogenhaltesystem besteht zumindest aus einer Mehrzahl von auf einer Greiferwelle 3 (mit Torsionsfeder 16) angeordneten Greifern 2 mit zugeordneter Greiferauflage 1. An der Greiferwelle 3 ist vorzugsweise endseitig ein Kurventrä-ger 4 fixiert, vorzugsweise lösbar, angeordnet. Dieser Kurventräger 4 ist mit der Rolle 12 des Rollenhebels 6 - alternativ mit einem Gleitsegment mit Hebel 6 - in der Paarungsstelle 13 kraftschlüssig in Eingriff. Der Hebel/Rollenhebel 6 ist mit einer ersten Schwinge 8 in dem ortsfesten Drehgelenk 7 gelagert. Hebel/Rollenhebel 6 und erste schwinge 8 stellen ein (im Drehgelenk 7 gelagertes) ternäres Glied mit drei Drehgelenkelementen, gebildet aus den Gelenken Rolle 12 bzw.

Das Drehgelenkelement 27 ist endseitig der ersten Schwinge 8 zugeordnet.In a further embodiment (FIG. 1), the drivable Bow holding system on a primary gear. For example, this is an advantage if space is unfavorable and / or unfavorable force relationships on the sheet holding system available. The sheet retention system consists of at least one Plurality of on a gripper shaft 3 (with torsion spring 16) arranged grippers 2 with assigned gripper pad 1. On the gripper shaft 3 is preferably a cam carrier at the end 4 fixed, preferably detachable, arranged. This curve bearer 4 is with the roller 12 of the roller lever 6 - alternative with a sliding segment with lever 6 - in the mating point 13 frictionally engaged. The lever / roller lever 6 is with a first rocker 8 in the fixed swivel 7 stored. Set lever / roller lever 6 and first rocker 8 a ternary member (mounted in the swivel 7) with three Swivel elements, formed from the joints roller 12 or Engagement member (sliding segment), swivel 7 and a swivel element 27, represents. The swivel element 27 is at the end assigned to the first rocker 8.

Weiterhin ist zusätzlich ein Drehgelenk 9 ortsfest am Bogenführungszylinder 18 angeordnet. Im Drehgelenk 9 sind ein Rollenhebel 15, welcher eine mit einer Steuerkurve 11 in Eingriff stehende Rolle 10 trägt, und eine zweite Schwinge 8 gelagert. Die Schwinge 8 weist endseitig ein Drehgelenkelement 26 auf. Beide Schwingen 8 sind mittels der Drehgelenkelemente 26, 27 mit einer Koppel 14 verbunden. Rollenhebel 15 und zweite Schwinge 8 stellen ein (im Drehgelenk 9 gelagertes) ternäres Glied mit drei Drehgelenkelementen, gebildet aus den Drehgelenken Rolle 10, Drehgelenk 9 und dem Drehgelenkelement 26, dar. Furthermore, a swivel joint 9 is also stationary on the sheet guide cylinder 18 arranged. In the swivel 9 are a Roller lever 15, which with a cam 11 in Engaged roller 10 carries, and a second rocker 8th stored. The rocker 8 has a swivel element at the end 26 on. Both rockers 8 are by means of the swivel elements 26, 27 connected to a coupling 14. Roller lever 15 and second rocker 8 set (mounted in the swivel 9) ternary link with three swivel elements, formed from the swivel rollers 10, swivel 9 and the swivel element 26, dar.

Als Vorschaltgetriebe erstreckt sich somit vom Drehgelenk 7 ein Viergelenkgetriebe (Positionen 7,27,26,9) zu dem am Bogenführungszylinder 18 angeordneten ortsfesten Drehgelenk 9.The primary transmission thus extends from the swivel joint 7 a four-bar gearbox (positions 7.27.26.9) to which on Bow guide cylinder 18 arranged fixed swivel 9.

In beiden Ausbildungen weist der Kurventräger 4 bevorzugt einen Kurvenast auf, der annähernd in Richtung der Achse des Bogenführungszylinders 18 zeigend kraftschlüssig, z.B. über die Torsionsfeder 16, mit der Rolle 12 bzw. dem Eingriffsglied gekoppelt ist.In both designs, the curve carrier 4 preferably has a curve branch that approximately in the direction of the axis of the Sheet guiding cylinder 18 non-positively, e.g. about the torsion spring 16, with the roller 12 or the engaging member is coupled.

In einer weiteren Ausbildung greift an dem Rollenhebel 15 eine am Bogenführungszylinder 18 gelagerte Feder an (nicht gezeigt), die eine verbesserte Anlage der Rolle 10 an der Steuerkurve 11 gewährleistet.In a further embodiment, the roller lever 15 engages a spring mounted on the sheet guide cylinder 18 (not shown), which is an improved installation of the roll 10 on the Control curve 11 guaranteed.

Das erfindungsgemäß mittels Kurvengelenk antreibbare Bogenhaltesystem ist dabei als Greifersystem 24 für den Widerdruck und/oder als Greifersystem 25 für den Schöndruck einsetzbar. Bei Ausbildung des Bogenführungszylinders 18 als Wendetrommel ist bevorzugt bei geschlossenen Greifern 2 der Achsmittelpunkt der Rolle 12 mit dem Achsmittelpunkt der zugeordneten, in Lagerelementen 17 drehbaren Schwenkwelle 5, deckungsgleich angeordnet (Fig.1).
Beim Ein-/Ausschwenken der Schwenkwelle 5 erfolgt keine rotative Bewegung zwischen Kurventräger 4 und Rolle 12. Beim Öffnen der Greifer 2 verlagert sich der Achsmittelmittelpunkt der Rolle 12 vom Achsmittelpunkt der Schwenkwelle 5 (Fig.2) weg.The sheet holding system which can be driven by means of a curved joint according to the invention can be used as a gripper system 24 for the counterpressure and / or as a gripper system 25 for the straight printing. When the sheet guiding cylinder 18 is designed as a turning drum, the center of the roller 12 is preferably congruently arranged with closed grippers 2 with the center of the axis of the associated pivot shaft 5 rotatable in bearing elements 17 (FIG. 1).
When the swivel shaft 5 is swiveled in and out, there is no rotary movement between the cam carrier 4 and the roller 12. When the grippers 2 are opened, the center of the axis of the roller 12 shifts away from the center of the axis of the swivel shaft 5 (FIG. 2).

Alternativ ist die Lage der Rolle 12 bei geschlossenen Greifern 2 frei wählbar. Der Kurvenast des Kurventrägers 4 ist dann - bezogen auf den Achsmittelpunkt der Schwenkwelle 5 - bevorzugt als Kreissegment ausgebildet. Beim Ein-/Ausschwenken der Schwenkwelle 5 rollt die Rolle 12 auf dem Kurvenast des Kurventrägers 4 ab, wobei ihr Achsmittelpunkt ortsfest zum Bogenführungszylinder 18 ist.Alternatively, the position of the roller 12 when the grippers are closed 2 freely selectable. The curve branch of the curve carrier 4 is then - based on the axis center of the swivel shaft 5 - preferably designed as a segment of a circle. When swiveling in / out the pivot shaft 5 rolls the roller 12 on the Curve branch of the curve carrier 4, with its axis center is stationary to the sheet guide cylinder 18.

Bei Ausbildung des Kurventrägers 4 mit in Richtung der Achse des Bogenführungszylinders 18 gerichtetem Kurvenast erfolgt über die belastete Torsionsfeder 16 die Öffnungsbewegung der Greifer 2 und über den Kurventräger 4 wird die Schliessbewegung der Greifer 2 eingeleitet.When the curve carrier 4 is formed with in the direction of the axis the curve guide cylinder 18 directed curve branch takes place the opening movement of the loaded torsion spring 16 Gripper 2 and over the cam carrier 4, the closing movement the gripper 2 initiated.

Alternativ ist der Kurvenast des Kurventrägers 4 - und damit die Paarungsstelle 13 - auch auf der von der Achse des Bogenführungszylinders 18 abgewandten Seite des Kurventrägers 4 anzuordnen. Die Rolle 12 liegt somit kraftschlüssig auf dem Kurventräger 4 auf. In dieser Ausbildung erfolgt über die belastete Torsionsfeder 16 die Schliessbewegung der Greifer 2 und über den Kurventräger 4 wird die Öffnungsbewegung der Greifer 2 eingeleitet. Die Rolle 12 mit Rollenhebel 6 ist ebenso durch ein Gleitsegment als Eingriffsglied mit Hebel 6 substituierbar. Alternatively, the curve branch of the cam bracket is 4 - and thus the mating point 13 - also on the axis of the sheet guide cylinder 18 opposite side of the curve carrier 4 to arrange. The roller 12 is thus non-positively on the Cam 4 on. In this training takes place over the loaded torsion spring 16, the closing movement of the gripper 2nd and the opening movement of the curve carrier 4 Gripper 2 initiated. The roller 12 with roller lever 6 is also by a sliding segment as an engagement member with lever 6 substitutable.
