Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Fördern von Bogen durch eine drucktechnische Maschine nach dem Oberbegriff des Anspruchs 1. Die Vorrichtung ist insbesondere bei Druckmaschinen anwendbar, bei denen Bogen in einem Durchgang wahlweise einseitig oder beidseitig bedruckt werden.The The invention relates to a device for conveying sheets through a Printing machine according to the preamble of claim 1. The device is particularly applicable to printing machines where sheets in A passage can be printed on one or both sides.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Fördern von Bogen durch eine drucktechnische Maschine zu entwickeln, die es ermöglicht, die Genauigkeit bei der Bogenübergabe zu verbessern und kostengünstige Greifersysteme zu verwenden.task The invention is a device for conveying sheets through a developing a printing machine that makes it possible the accuracy of sheet transfer to improve and cost-effective To use gripper systems.
Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object is achieved with a device which the features Claim 1. Advantageous embodiments emerge the dependent claims.
Gemäß der Erfindung werden die Bogen nacheinander von einer Übertragungstrommel auf eine benachbarte Übertragungstrommel gefördert, wobei auf der Übertragungstrommel, die den Bogen abgibt, mindestens ein Greifer vorgesehen ist, mit dem jeweils die Bogen an der Hinterkante bzw. der Umgebung der Hinterkante von der Auflagefläche auf der Übertragungstrommel so abgehoben wird, dass ein Greifer auf der Übertragungstrommel, die den Bogen empfängt, den Bogen an der Hinterkante übernehmen kann. Der Greifer an der übergebenden Übertragungstrommel ist hierzu mit einer radialen Komponente beweglich. Der Greifer an der übergebenden Übertragungstrommel ist vorteilhaft als Sauggreifer ausgebildet und mit einem Getriebe gekoppelt. Besonders geeignet ist ein Viergelenkgetriebe, welches mit einem Kurvengetriebe gekoppelt ist. Alternative Antriebe für die Greifer auf der übergebenden Übertragungstrommel sind Linearaktoren, elektromechanische oder pneumatische Stellglieder; gegebenenfalls in Verbindung mit Getriebegliedern, wie Hebel, Kurven oder Exzenter.According to the invention The sheets are successively from a transfer drum to a adjacent transfer drum promoted, being on the transfer drum, which gives the bow, at least one gripper is provided with the in each case the bows at the trailing edge or the surroundings of the trailing edge from the support surface on the transfer drum is lifted so that a gripper on the transfer drum, the Bow receives, take over the bow at the trailing edge can. The gripper on the transferring transfer drum is this movable with a radial component. The gripper at the transferring drum is advantageously designed as a suction pad and with a transmission coupled. Particularly suitable is a four-bar linkage, which is coupled with a cam mechanism. Alternative drives for the grippers on the transferring drum are linear actuators, electromechanical or pneumatic actuators; possibly in conjunction with gear elements, such as levers, curves or eccentrics.
Die Greifer auf der übernehmenden Übertragungstrommel, welche den Bogen an der Hinterkante übernehmen, sind vorteilhaft als Zangengreifer ausgebildet. Die Zangengreifer sind um eine Achse drehbar, die parallel zur Rotationsachse und deutlich innerhalb der Umlaufkontur der Übertragungstrommel liegt.The Gripper on the transferring drum, which take the bow at the trailing edge, are advantageous designed as a forceps gripper. The forceps grippers are around an axis rotatable, parallel to the axis of rotation and clearly within the circulation contour of the transfer drum is located.
Zur Straffung des Bogens kann der Greifer an der übergebenden Übertragungstrommel, neben der radialen auch eine tangentiale Bewegung ausführen. Zum Stützen des Bogens im heraus geschwenkten Zustand der Greifer kann an der übergebenden Übertragungstrommel mindestens ein Führungsblech vorgesehen sein.to Tightening of the bow, the gripper at the transferring transfer drum, In addition to the radial and perform a tangential movement. To the Support The bow in the pivoted out state of the gripper can at the transferring transfer drum at least one guide plate be provided.
Die Erfindung ist bei Bogendruckmaschinen mit Dreitrommelwendung einsetzbar. Die Erfindung vermeidet den Einsatz von aufwendigen Greifersystemen an der übergebenden Übertragungstrommel und an dem übernehmenden Druckzylinder, die als sogenannte Hakengreifer speziell ausgebildet sind und eine Kollision mit einem Zangengreifersystem auf einer Wenderommel ausschließen.The The invention can be used in sheet-fed presses with three-drum turning. The invention avoids the use of expensive gripper systems at the transfer drum and transferring at the acquiring Printing cylinders, which are specially designed as so-called hook grippers are and a collision with a forceps gripper system on one Exclude turning drum.
