Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Umstülpen eines Bogens um eine Querachse während eines Förderns zwischen zwei Druckwerken einer Druckmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for everting a Arch around a transverse axis during a conveying between two printing units of a printing press according to the preamble of claim 1.
Um die Fertigungskosten niedrig zu halten, werden Druckmaschinen mit gleichartigen Druckwerken ausgestattet, die einen hohen Wiederholteilgrad aufweisen. Typisch ist eine Reihenanordnung von gleichartigen Druckwerken, mit denen jeweils ein Teilfarbenbild auf eine Seite eines Bogens gedruckt wird. Mit Registervorrichtungen wird sichergestellt, dass beim Übereinanderdruck die relative Lage der Teilfarbenbilder so ist, dass ein gewünschter Farbeindruck entsteht. Wird ein Auftrag zum Drucken auf beiden Seiten der Bogen abgearbeitet, werden die Bogen nach dem Bedrucken der Vorderseite gewendet, wobei zwischen zwei Druckwerken der Reihenanordnung eine Wendevorrichtung angeordnet ist. Die Wendevorrichtung bewirkt ein Umstülpen um eine Querachse oder ein Umschlagen um eine Längsachse. Nach einem Umstülpen werden die Bogen an dem Rand voraus durch die Druckwerke zum Drucken auf der Rückseite gefördert, der beim Drucken auf der Vorderseite nachlaufend war. Während eines Umstülpens wird ein Bogen in Greifern gehalten und durch mechanische oder pneumatische Leitelemente geführt. Ziel ist es, einen Bogen und dessen Aufdruck während des Förderns in der Wendevorrichtung nicht zu beschädigen und den Bogen so an Greifer eines Druckzylinders zu übergeben, dass der Aufdruck auf der Rückseite im Register zum Aufdruck auf der Vorderseite steht.Around To keep the manufacturing costs down, presses are with equipped similar printing units, which have a high degree of repetition. Typical is a series arrangement of similar printing units, with each a partial color image on one side of a sheet is printed. Register devices ensure that when overprinting the relative position of the partial color images so is that a desired color impression arises. Becomes an order for printing on both sides of the sheet processed, the sheets are turned after printing the front, where between two printing units of the series arrangement a turning device is arranged. The turning device causes an eversion about a transverse axis or a turning around a longitudinal axis. After an everting, the bows are ahead of the edge promoted by the printing units for printing on the back, which was trailing when printing on the front. While an everting a bow is held in claws and through guided mechanical or pneumatic guide elements. aim is it a bow and its imprint while promoting in the turning device not to damage and the bow so to gripper of a printing cylinder to pass that the Imprint on the back in the register for printing on the front is.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Umstülpen eines Bogens um eine Querachse während eines Förderns zwischen zwei Druckwerken einer Druckmaschine zu entwickeln, bei der eine Kollision mit Bogenführungselementen eines nachfolgenden Bogens verhindert ist.task The invention is an apparatus for everting a Arch around a transverse axis during a conveying develop between two printing units of a printing press, at a collision with sheet guiding elements of a subsequent Bow is prevented.
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 ist an einer Speichertrommel, die einen Bogen am vorderen Rand hält und den Bogen um eine Querachse umführt, mindestens ein Separator angeordnet, der während eines Umlaufs der Speichertrommel aus der Umlaufkontur der Speichertrommel herausfährt und zurückgezogen wird. Ein Fördern des Bogens von der Speichertrommel zu einem Greifersystem eines Druckzylinders eines ersten Widerdruckwerks kann mit einer Übertragungstrommel, einem endlosen Förderer oder mittels eines Schwinggreifersystems vorgenommen werden. Der Separator kann als geschlossenes Blech oder in Form von mehreren parallel angeordneten Bügeln vorgesehen werden. Zum wiederkehrenden Ein- und Ausfahren des Separators können mechanische Getriebe und/oder elektromechanische Antriebe vorgesehen werden. Der Separator kann mit einer steuerbaren Saugluftquelle oder einer Blasluftquelle mit Venturidüsen zusammenwirken, wobei die Luft abhängig von der Drehstellung der Speichertrommel gestellt wird. Der Separator wird zyklisch zwischen einen abgehenden und einem nachfolgenden Bogen gefahren, so dass der abgehende Bogen nicht den ankommenden Bogen bzw. ein Greifersystem berührt.According to the Invention is connected to a storage drum, which has a bow at the front Edge holds and the bow around a transverse axis, at least one separator arranged during a Circulation of the storage drum from the circulation contour of the storage drum is withdrawn and withdrawn. A promoting of the sheet from the storage drum to a gripper system of a Printing cylinder of a first perfecting unit can with a transfer drum, an endless conveyor or by means of a swing gripper system be made. The separator can be used as a closed sheet metal or provided in the form of several parallel brackets become. For recurrent retraction and extension of the separator can mechanical transmission and / or electromechanical drives provided become. The separator can be equipped with a controllable suction air source or a blast air source interact with venturi nozzles, wherein the air is set depending on the rotational position of the storage drum becomes. The separator is cyclically between an outgoing and a drove a subsequent arc, so that the outgoing bow not touched the incoming sheet or a gripper system.
