Abstract
Einrichtung zum Zuführen von Bogen von einem Bogenstapel zu einer Bogentransporttrommel einer Druckmaschine, dadurch gekennzeichnet, daß vor einem die Bogen von einem Anlegtisch (9) übernehmenden und an die Bogentransporttrommel (3) übergebenden Vorgreifer (13) oberhalb des Bogenstapels (2) ein den obersten Bogen (1) erfassendes, vom Bogenstapel trennendes und über den Anlegtisch (9) zu Anlegmarken (10) transportierendes, mindestens einen Sauger (19) enthaltendes und mit einem Schwingantrieb verbundenes Transportelement (6) angeordnet ist, wobei dem Sauger (19) ein Verstellgetriebe derart zugeordnet ist, daß die Saugerfläche des Saugers (19) zum Freigabepunkt (12) des Bogens (1) an den Anlegmarken (10) parallel oder nahezu parallel zur Ebene des Anlegtisches (9) und die Erstreckungsrichtung (20) des Saugers (19) zum Bogenübernahmepunkt (22) in Bogenförderrichtung (21) gesehen unter einem wählbaren Winkel (α) relativ zur Bogenstapelebene (23) angeordnet ist.Device for feeding sheets from a stack of sheets to a sheet transport drum of a printing machine, characterized in that in front of a pre-gripper (13) above the sheet stack (2), which takes over the sheets from a feed table (9) and transfers them to the sheet transport drum (3) Transport element (6), which detects the sheet (1) and separates it from the sheet stack and transports it over the feed table (9) to feed marks (10), and contains at least one suction pad (19) and is connected to a vibratory drive, wherein the suction pad (19) has an adjusting mechanism is assigned in such a way that the suction surface of the suction device (19) to the release point (12) of the sheet (1) on the contact marks (10) is parallel or almost parallel to the plane of the contact table (9) and the direction of extension (20) of the suction device (19) to the sheet transfer point (22) in the sheet conveying direction (21) is arranged at a selectable angle (α) relative to the sheet stacking plane (23).
Description
Die Erfindung betrifft eine Einrichtung zum Zuführen von Bogen von einem Bogenstapel zu einer Bogentransporttrommel einer Druckmaschine.The invention relates to a device to feed of sheets from a sheet stack to a sheet transport drum Press.
Es ist eine Bogenzuführung im
Anleger einer Bogendruckmaschine bekannt (
Nachteilig bei dieser Bogenführung sind die langen Transportwege sowie die unterschiedlichen Angriffspunkte der Transportelemente an und auf dem Bogen, die diese Bogenführung für schnellaufende Maschinen aufgrund des freien Bogenanfanges für die Verarbeitung dünner Bedruckstoffe und aufgrund der Verwendung nur eines Hubsaugers für die Verarbeitung von biegeschlaffen und schweren Bedruckstoffen sowie von großformatigen Bogen ungeeignet machen.Disadvantages of this sheet guide are the long transport routes and the different points of attack of the transport elements on and on the sheet that this sheet guide for fast moving Machines due to the free start of the sheet for processing thin substrates and due to the use of only one suction cup for processing of limp and heavy substrates as well as large format Make the bow unsuitable.
Des weiteren erfordert diese Bogenführung großen Bauraum. Letztendlich ist diese Bogenführung aufgrund fehlender Anpassung an unterschiedliche Materialien nicht universell einsetzbar.Furthermore, this sheet guide requires large installation space. Ultimately, this is arch guidance due to the lack of adaptation to different materials universally applicable.
Aus der
Aufgabe der Erfindung ist die Schaffung einer Einrichtung zum Zuführen von Bogen für schnellaufende Maschinen mit hoher Zuführgenauigkeit auch bei dünnen Bedruckstoffen, mit geringem Bauraum und Anpassungsmöglichkeiten an unterschiedliche Bedruckstoffe während des Bogenlaufes.The object of the invention is to create a device for feeding of bow for high-speed machines with high feeding accuracy even with thin substrates, with little space and adaptability to different Substrates during of the sheet run.
Erfindungsgemäß wird die Aufgabe durch die Patentansprüche 1 oder 2 gelöst.According to the invention, the object is achieved by claims 1 or 2 solved.
Nachfolgend wird die erfinderische Lösung an einem Ausführungsbeispiel näher erläutert.Below is the inventive one Solution an embodiment explained in more detail.
