Description

Die Erfindung bezieht sich auf eine Vorrichtung zum seitlichen Ausrichten von Bögen in einer Bogenrotationsdruckmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for laterally aligning sheets in a sheet-fed rotary printing press after the generic term of Claim 1.

Aus der EP-OS 0 120 348 ist eine Vorrichtung bekannt, bei der ein Ausrichtzylinder zwischen dem Anlegetisch und einem Vorgreiferzylinder angeordnet ist, dem der auszurichtende Bogen über den Anlegetisch zugeführt wird. Im Ausrichtzylinder sind symmetrisch zum Umfang wenigstens zwei Reihen Vordermarken vorgesehen, denen Ziehleisten zur Seitenkantenausrichtung zugeordnet sind, wobei Greifer den Bogen solange führen, bis ihn weiterführende Transportmittel paßgerecht übernehmen. Die zwangsläufige Vorderkantenausrichtung sowie das feste Halten des Bogens während seiner seitlichen Ausrichtung erhöhen die Ausrichtgenauigkeit. Bei geschuppter Bogenführung wird eine Verringerung des Schuppenabstandes ermöglicht. Der zur Erreichung dieses Vorteils erforderliche technische Aufwand ist jedoch erheblich.From EP-OS 0 120 348 is a device known, in which an alignment cylinder between the Laying table and a pre-gripper cylinder arranged is that the bow to be aligned on the feed table is supplied. In the alignment cylinder are symmetrical to the extent of at least two rows Front brands provided, which pull strips for side edge alignment are assigned, with grippers lead the bow until it continues Appropriately transporting means of transport. The inevitable Leading edge alignment and firm holding the bow during its lateral alignment increase the alignment accuracy. When shingled Bowing will reduce the scale spacing allows. The achievement of this advantage However, required technical effort is considerably.

Eine elektronische Vorrichtung zur Kontrolle der Bogenlage am Zylinder einer Druckmaschine ergibt sich aus der DE 41 13 478 A1. Abtastelemente aus CCD-Zeilen und einer Lichtquelle ermitteln die Lage der Bogenvorderkante, um eine passerhaltige Bogenübergabe zu gewährleisten. Vorwiegend gekrümmte Bogenvorderkanten sollen dadurch erkannt werden, um mögliche Fehler durch Veränderung der Druckparameter zu korrigieren. Erwähnt wird in dieser Druckschrift, daß es durch diese Kontrolle der Bogenlage möglich ist, die Bogenvorderkante im Greifersystem eines jeden Druckwerkes zu erfassen, um Lageveränderungen bei der Bogenübergabe zwischen den Druckwerken oder innerhalb der Druckwerke zu erkennen.An electronic device for controlling the Sheet position on the cylinder of a printing press results from DE 41 13 478 A1. Scanning elements CCD lines and a light source determine the location of the Arch leading edge to a passerhaltige sheet transfer to ensure. Predominantly curved sheet leading edges should be recognized by, um possible errors by changing the pressure parameters to correct. Mention is made in this document, that it is possible by this control of the sheet position, the sheet leading edge in the gripper system of each To capture changes in position the sheet transfer between the printing units or to recognize within the printing units.

Aus der DE-OS 22 20 625 ist eine Vorrichtung zum seitlichen Ausrichten von Bögen im Anleger einer Bogenrotationsmaschine bekannt, bei dem Meßelemente die Istlage einer Seitenkante des Bogens auf dem Anlegetisch der Maschine ermitteln und ein Greifersystem an einem nachfolgendem Zylinder durch motorische Stellglieder seitlich verschoben wird. Die Verschiebung erfolgt dort durch Schrittmotore.From DE-OS 22 20 625 a device for lateral alignment of sheets in the feeder of a Sheet rotation machine known in the measuring elements the actual position of a side edge of the bow determine the feed table of the machine and a gripper system on a subsequent cylinder motor actuators is shifted laterally. The Shifting takes place there by stepper motors.

Die DE 36 44 431 A1 beschreibt einen seitlich in einem Zylinder verschiebbare Greiferauflage zum seitlichen Ausrichten der zu bedruckenden Bogen, der über eine Steuerscheibe permanent bei jeder Zylinderumdrehung verschoben wird. Abweichungen der Seitenkantenlage des Bogens werden einem Getriebemotor zugeführt, der wiederum die Steuerscheibe verstellt.DE 36 44 431 A1 describes a side in a cylinder sliding gripper pad for lateral Align the sheet to be printed, the over a control disc permanently with each cylinder revolution is moved. Deviations of the side edge position The bow becomes a geared motor fed, which in turn adjusts the control disk.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die durch Fehler in der seitlichen Bogenausrichtung entstehenden Probleme mit möglichst geringem Aufwand durch sichere Betriebsmittel zu minimieren und dadurch auch höhere Maschinengeschwindigkeiten zur Steigerung der Druckleistung zu ermöglichen.The present invention has the object underlying, due to errors in the lateral sheet orientation arising problems with the least possible Effort through secure equipment too minimize and thereby also higher machine speeds to increase the pressure power too enable.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, eine Vorrichtung nach dem Oberbegriff mit Merkmalen nach dem Kennzeichen des Patentanspruches 1 auszubilden.To achieve this object is according to the invention provided, a device according to the preamble Features according to the characterizing part of claim 1 train.

Erfindungsgemäß erfolgt die Seitenausrichtung der Bögen durch eine axial verschiebliche Anordnung eines Greifersystems aus einer Greiferbrücke mit daran befestigten Bogengreifern im Kanal eines Zylinders der Druckmaschine durch elektrisch ansteuerbare lineare Aktoren bzw. Linearmotoren wie beispielsweise Piezoelemente als Stellglieder. Dies ergibt eine bessere Verarbeitung der Meßwerte im Steuerprogramm zur Betätigung der Stellglieder und mehr Zeit für die seitliche Verschiebung des Greifersystems. Besondere Einzelheiten zur Gestaltung der erfindungsgemäßen Lösung ergeben sich auch aus der noch folgenden Beschreibung eines Ausführungsbeispieles.According to the invention, the page orientation of the Arches by an axially displaceable arrangement of a Gripper system from a gripper bar with it attached Bow grippers in the channel of a cylinder Printing machine by electrically controllable linear Actuators or linear motors such as piezo elements as actuators. This results in better processing of the measured values in the control program for Actuation of the actuators and more time for the lateral Displacement of the gripper system. Special details for the design of the invention Solution also result from the following Description of an embodiment.

Gegenüber dem Stande der Technik wird durch die Erfindung eine einfache Lösung zur seitlichen Bogenausrichtung geschaffen und ein wesentlicher Zeitgewinn für die seitliche Bogenausrichtung mit hoher Sicherheit für die Ausrichtgenauigkeit erreicht. Eine Zieheinrichtung herkömmlicher Art ist nicht mehr erforderlich. Der Anlegetisch kann somit eine glatte Oberfläche aufweisen, so daß keine Stolperstellen für den Bogen durch Schraubenköpfe, Faltenbälge oder dergleichen, vorhanden sind. Die Saugbänder lassen sich bis an die Vordermarken heranführen, so daß Vordermarkenbläser und eventuell auch ein Deckrechen entfallen können. Für die Umfangsausrichtung der Bögen wird durch den Wegfall des Ziehvorganges Zeit gewonnen, wobei der Wegfall der Zieheinrichtung kürzere Schuppenabstände ermöglicht als bisher. Dies erlaubt eine Steigerung der Maschinengeschwindigkeit bei sicherem Papierlauf und hoher Umfangspasserqualität, die nicht sehr durch die seitliche Ausrichtung der Bögen beeinflußt wird. Schließlich lassen sich Einrichtzeiten für die Maschine reduzieren, weil die Einstellung von Ziehmarken und Blasluft, eventuell auch eines Deckrechens, entfällt.Compared to the prior art is by the Invention a simple solution for lateral sheet alignment created and a significant time saving for the lateral sheet alignment with high Safety achieved for the alignment accuracy. A Pulling device of conventional type is no longer required. The feed table can thus have a smooth surface have, so that no stumbling for the Bows through screw heads, bellows or the like, available. The suction belts can be bring up to the leading brands, so that Vordermarkenbläser and possibly even a cover rake omitted can. For the circumferential alignment of the sheets is gained by the elimination of the drawing time, whereby the omission of the pulling device shorter Scales distances enabled as before. This allows an increase in machine speed safe paper handling and high perimeter quality, not very much because of the lateral orientation of the bows being affected. Finally set up times reduce for the machine because the setting of Ziehmarken and blown air, possibly also a covering rake, eliminated.

Bei dem dargestellten Ausführungsbeispiel werden die zu bedruckenden Bögen vom Anleger 1 über einen Anlegetisch 3 durch einen Vorgreifer 11 und einen Zuführzylinder 6 dem Druckzylinder 4 eines ersten Druckwerks 2 zugeführt. Die Bögen gelangen auf dem Anlegetisch 3 mit ihrer in Transportrichtung vorderen Kante zur Vorderkantenausrichtung gegen Vordermarken 13. Ein optoelektronischer Sensor 14 mit einer integrierten Beleuchtung ermittelt die Ist-Lage wenigstens einer Bogenseitenkante und gibt diese Meßwerte zu einem Soll-Ist-Vergleich in einen Regler 15 ein. Gemäß der Darstellung in Figur 2 erfassen Bogengreifer 12 die Vorderkante des gegen die Vordermarken 13 ausgerichteten Bogens 19, so daß der Bogen zwischen den Bogengreifern 12 und den Greiferauflagen 17 an einer Greiferauflagenleiste 18 sicher gehalten wird. Bei weggeschwenkten Vordermarken 13 wird der Bogen durch den Vorgreifer 11 mit einer Schwenkbewegung um die Achse der Vorgreiferwelle 24 vom Anlegetisch 3 dem Greifersystem des Zuführzylinders 6 übergeben. Gemäß der beispielhaften Darstellung in der Figur 3 besteht auch dieses Greifersystem aus einer Greiferbrücke 7 mit daran befestigten Bogengreifern 8, wobei dieses Greifersystem in dem Zylinderkanal 25 des Zuführzylinders 6 axial verschieblich angeordnet ist. Eine Greiferauflageleiste 28, an der die Greiferauflagen 27 für die Bogengreifer 8 ausgebildet sind, ist an einem Linearführungswagen 36 befestigt, welcher in Linearführungsschienen beweglich ist, die an einer Seitenwand des Zylinderkanals 25 befestigt sind. Am Ende einer Greiferwelle 26 ist ein durch eine Kurve gesteuerter Rollenhebel 37 für das Öffnen und Schließen der Bogengreifer 8 angeordnet. Die axiale Verstellung der durch die Greiferauflagenleiste 28 gebildeten Greiferbrücke 7 erfolgt durch einen Linearmotor 9 in einem Linearmotorgehäuse 30, welches in einem Motorlager 23 am Boden des Zylinderkanals 25 abgestützt ist. Ein Linearmotorstößel 31 des Linearmotors 9 ist mit einem Verbindungselement 33 verbunden, welches an der Greiferauflagenleiste 28 befestigt ist. Der Linearmotor 9 erhält Steuerimpulse, die sich aufgrund eines vorgegebenen Rechnerprogramms aus dem Soll-Ist-Vergleich im Regler 15 ergeben. Entsprechend der vom Sensor 14 ermittelten Abweichung der Seitenkantenlage des Bogens auf dem Anlegetisch 3 von seiner Soll-Lage erfolgt somit über den Regler 15 eine Axialverschiebung der Greiferbrücke 7 im Zylinderkanal 25 des Zuführzylinders 6, so daß die Seitenkantenfehllage des Bogens durch eine axiale Verschiebung der Greiferbrücke 7 im Zylinderkanal 25 des Zuführzylinders 6 korrigiert wird.In the illustrated embodiment will be the sheets to be printed from the feeder 1 via a Feed table 3 by a pre-gripper 11 and a Feed cylinder 6 the pressure cylinder 4 of a first Fed printing unit 2. The arches arrive on the Feed table 3 with their front in the transport direction Edge for leading edge alignment against leading brands 13. An optoelectronic sensor 14 with an integrated Illumination determines the actual position at least a sheet side edge and gives these readings a target-actual comparison in a controller 15 a. According to The illustration in Figure 2 detect sheet gripper 12 the Leading edge of the aligned against the front lays 13 Bow 19, so that the bow between the Sheet grippers 12 and the gripper pads 17 at a Gripper pad strip 18 is held securely. With weggeschwenkten Leading 13 is the bow through the pre-gripper 11 with a pivoting movement about the Axis of the pre-gripper shaft 24 from the feed table 3 the Gripper system of the feed cylinder 6 pass. According to the exemplary illustration in FIG. 3 This gripper system consists of a gripper bridge 7 with attached sheet grippers 8, wherein this gripper system in the cylinder channel 25 of the Feed cylinder 6 is arranged axially displaceable. A gripper support bar 28 on which the gripper pads 27 are formed for the sheet gripper 8 is at a Linear guide carriage 36 attached, which in linear guide rails it is movable on a side wall the cylinder channel 25 are attached. At the end a gripper shaft 26 is a controlled by a curve Roller lever 37 for opening and closing the Sheet gripper 8 arranged. The axial adjustment of gripper bridge formed by the gripper support rail 28 7 takes place by a linear motor 9 in one Linear motor housing 30, which in an engine mount 23 is supported at the bottom of the cylinder channel 25. One Linear motor tappet 31 of the linear motor 9 is connected to a Connecting element 33 connected, which at the Gripper pad strip 28 is attached. The linear motor 9 receives control impulses that are due to a given Computer program from the target-actual comparison in the controller 15 result. According to the sensor 14 determined deviation of the side edge position of Arch on the feed table 3 from its nominal position Thus, via the controller 15 is an axial displacement the gripper bridge 7 in the cylinder channel 25 of the feed cylinder 6, so that the side edge misalignment of the bow by an axial displacement of the gripper bridge 7 in Cylinder channel 25 of the feed cylinder 6 is corrected.
