Abstract
Ein Bogenentroller einer Druckmaschine umfasst eine erste Walze (1), einen ersten Antrieb (11) zum Rotieren der ersten Walze, eine zweite Walze (2), wobei die zweite Walze der ersten Walze in Bogenförderrichtung (BFR) der zu entrollenden oder zu glättenden Bogen folgt. Der erste Antrieb ist durch eine Steuerung (17) derart angesteuert, dass bei konstanter Druckgeschwindigkeit der Druckmaschine die erste Walze im Fördertakt der Bogen ungleichförmig rotiert. A sheet troller of a printing machine comprises a first roller (1), a first drive (11) for rotating the first roller, a second roller (2), the second roller of the first roller in the sheet conveying direction (BFR) of the sheets to be unrolled or smoothed follows. The first drive is controlled by a controller (17) such that at constant printing speed of the printing press, the first roller rotates unevenly in the conveying cycle of the sheet.
Description
Vorliegende Erfindung betrifft einen Bogenentroller einer Druckmaschine, der eine erste Walze, eine zweite Walze, die der ersten Walze in Bogenförderrichtung der zu entrollenden oder zu glättenden Bogen folgt, und einen sich zwischen der ersten Walze und der zweiten Walze befindenden Zwischenraum umfasst.The present invention relates to a sheet troller of a printing machine comprising a first roller, a second roller following the first roller in the sheet conveying direction of the sheets to be unrolled or smoothed, and a space located between the first roller and the second roller.

Der Erfindung liegt die Aufgabe zugrunde, einen weiteren Bogenentroller zu schaffen.The invention has for its object to provide a further sheet troller.
Diese Aufgabe wird durch einen Bogenentroller mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a sheet troller with the features of claim 1.
Der erfindungsgemäße Bogenentroller in einer Druckmaschine umfasst eine erste Walze, einen ersten Antrieb zum Rotieren der ersten Walze, eine zweite Walze, wobei die zweite Walze der ersten Walze in Bogenförderrichtung der zu entrollenden oder zu glättenden Bogen folgt, sich zwischen der ersten Walze und der zweiten Walze ein Zwischenraum befindet und der erste Antrieb durch eine Steuerung derart angesteuert ist, dass bei konstanter Druckgeschwindigkeit der Druckmaschine die erste Walze im Fördertakt der Bogen ungleichförmig rotiert.The sheet troller according to the invention in a printing machine comprises a first roller, a first drive for rotating the first roller, a second roller, the second roller of the first roller follows in the sheet conveying direction of the sheet to be unrolled or smoothing, between the first roller and the second Roller is a gap and the first drive is controlled by a controller such that at constant printing speed of the printing press, the first roller in the conveying cycle of the sheet rotates unevenly.
Ein Vorteil des erfindungsgemäßen Bogenentrollers besteht in dessen besonders guter Eignung für Bogen aus vergleichsweise steifem Material.An advantage of the sheet troller according to the invention consists in its particularly good suitability for sheets of relatively stiff material.
Es sind verschiedene Weiterbildungen des erfindungsgemäßen Bogenentrollers möglich. Der erste Antrieb kann ein Elektromotor sein. Es kann ein zweiter Antrieb zum Rotieren der zweiten Walze vorhanden sein. Der zweite Antrieb kann ein Elektromotor sein. Der zweite Antrieb kann durch die Steuerung derart angesteuert sein, dass bei konstanter Druckgeschwindigkeit der Druckmaschine die zweite Walze im Fördertakt der Bogen ungleichförmig rotiert. Der Zwischenraum kann durch einen Vakuumerzeuger mit Saugluft beaufschlagt sein. In dem Zwischenraum kann ein Abstützelement angeordnet sein, das eine dem Bogen zugewandte Stützfläche hat. Die Stützfläche kann eine in Bogenförderrichtung verlaufende, konkave Krümmung mit einem Radius haben. Über dem Zwischenraum kann ein Blasrohr angeordnet sein, das den Bogen in den Zwischenraum drängt. Die erste Walze und die zweite Walze können jeweils in ihrer Umfangsfläche Nuten haben, die Passagen für Greifer bilden, die den Bogen festhalten.There are various developments of the invention Bogenentrollers possible. The first drive may be an electric motor. There may be a second drive for rotating the second roller. The second drive may be an electric motor. The second drive may be controlled by the controller such that at constant printing speed of the printing press, the second roller rotates non-uniformly in the conveying cycle of the sheet. The gap can be acted upon by a vacuum generator with suction. In the intermediate space, a support element may be arranged, which has a support surface facing the arc. The support surface may have a bow-shaped, concave curvature having a radius. Over the gap, a blowpipe may be arranged which urges the sheet into the gap. The first roller and the second roller may each have in their peripheral surface grooves that form passages for grippers that hold the sheet.
