Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Wenden eines Bogens während des Förderns durch eine Druckmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for turning a sheet during of conveying by a printing press according to the preamble of claim 1.

Bei den Lösungen nach dem Stand der Technik wird ein Bogen im Wendebetrieb stark beschleunigt. Die beim Abbremsen und erneuten Beschleunigen auftretenden Kräfte müssen von den Greifern aufgenommen werden, die entsprechend hohe Bogenhaltekräfte aufbringen müssen. Während einer Gleichlaufphase von Greifersystemen bei einer Übergabe eines Bogens am nachlaufenden Bogenrand von einer Speichertrommel an eine Wendetrommel wird der Bogenrand girlandenartig gebogen, weil sich die Greifflächen von Zangengreifern an der Wendetrommel von den Auflageflächen von Sauggreifern der Speichertrommel entfernen. Bei der Übernahme des Bogens am hinteren Bogenrand liegen die Greifflächen von Zangengreifern nicht in Bogenlaufrichtung, so dass es möglich ist, dass der Bogen am hinteren Bogenrand geknickt wird.at the solutions of the prior art is a bow greatly accelerated during turning operation. When braking and again Accelerate occurring forces must by the Grippers are received, the correspondingly high sheet holding forces have to raise. During a synchronization phase of gripper systems at a handover of a sheet on trailing edge of the sheet from a storage drum to a turning drum the sheet edge is like a garland bent, because the gripping surfaces of pincer grippers on the turning drum of the bearing surfaces Remove from suction pads of the storage drum. In the acquisition of the Arch at the rear edge of the sheet are the gripping surfaces of Pliers grab not in sheet travel direction, making it possible is that the bow is kinked at the back edge of the sheet.
Aufgabe der Erfindung ist es, eine Vorrichtung zum Wenden eines Bogens zu entwickeln, die mit geringem Material- und Kostenaufwand einen sanften Bogenlauf ermöglicht.task The invention is to a device for turning a bow to develop, which with low material and cost a gentle Sheet travel allows.
Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Task is solved with a device which features according to claim 1. Advantageous embodiments arise from the dependent claims.
Gemäß der Erfindung wird eine Greiferwelle mit auf Abstand gesetzten Greifern am Trommelkörper einer Wendetrommel schwenkbar in Hebeln gehalten. Die Hebel sind mit einem Schwenkantrieb verbunden, der einem Bogen eine Bewegungscharakteristik aufprägt, so dass die Beschleunigung des in den Greifern gehaltenen Bogens minimiert ist. Dadurch wird eine Verformung des Bogenrandes gemindert, indem die Greifflächen der Greifer der Umlaufkontur einer vorgeordneten Speichertrommel nachgeführt werden.According to the Invention is a gripper shaft with spaced grippers on the drum body of a turning drum pivotable in levers held. The levers are connected to a rotary actuator, the imprinting a movement characteristic on a sheet so that the acceleration of the bow held in the grippers is minimized is. As a result, a deformation of the sheet edge is reduced by the gripping surfaces of the gripper of the circumferential contour of an upstream Storage drum to be tracked.
Gemäß einer Variante der Erfindung dient als Schwenkantrieb der Hebel ein Kurvengetriebe mit gestellfesten Kurven und an den Hebeln angeordneten Kurvenrollen.According to a variant of the invention serves as Swivel drive of the levers a cam mechanism with frame-fixed curves and arranged on the levers cam rollers.
Die Greifer der Wendetrommel führen eine Schwenkbewegung um die Greiferwelle aus, wobei ein Ritzel an der Greiferwelle mit einem Zahnsegment in Eingriff steht.The Grippers of the turning drum convert a pivoting movement the gripper shaft, wherein a pinion on the gripper shaft with a Toothed segment is engaged.
Gemäß einer Variante ist das Zahnsegment fest am Trommelkörper der Wendetrommel angeordnet. In diesem Fall können die gemeinsame Achse der Hebel, die Greiferwellenachse und die Umlaufachse der Wendetrommel in einer gestreckten Lage der Greiferfinger im wesentlichen in einer Ebene tangential zur vorgeordneten Speichertrommel liegen. Mit dieser Anordnung der Zahnsegmente ist die Greiferwellenachse der Wendetrommel nach einer Übernahme des Bogens am hinteren Bogenrand entgegen der Drehrichtung des Trommelkörpers bewegbar. Bei dieser Variante können an der Wendetrommel gerade Zangengreifer verwendet werden, bei denen die Greiferwellenachse und die Greifflächen etwa in einer Ebene liegen.According to one Variant is the toothed segment fixed to the drum body of Turning drum arranged. In this case, the common Axis of the levers, the gripper shaft axis and the axis of rotation of the Turning drum in an extended position of the gripper fingers substantially lie in a plane tangent to the upstream storage drum. With this arrangement of the toothed segments is the gripper shaft axis of the Turning drum after taking over the bow at the rear Bow edge against the direction of rotation of the drum body movable. With this variant can at the turning drum straight clamp grippers are used where the gripper shaft axis and the gripping surfaces lie approximately in one plane.
Gemäß einer weiteren Variante ist das Zahnsegment um die Achse der Hebel schwenkbar angeordnet. Eine Schwenkbewegung des Zahnsegmentes kann mit einer gestellfesten Kurve und einer Kurvenrolle am Zahnsegment erreicht werden. Bei dieser Variante ist es vorteilhaft, die Greifer der Wendetrommel als abgewinkelte Zangengreifer auszubilden.According to one Another variant, the toothed segment is pivotable about the axis of the lever arranged. A pivoting movement of the toothed segment can with a frame-fixed curve and a cam roller reached on the toothed segment become. In this variant, it is advantageous, the gripper of the Turning drum form as angled pliers gripper.
