Description

Die Erfindung betrifft eine Vorrichtung zum seitlichen Ausrichten von Bogen in einer Bogenrotationsdruckmaschine mit einem in einem Zylinder axial verschiebbar gelagerten Greifersystem, das durch ein über eine Auswerteinheit beeinflussbares Stellglied verschoben werden kann.The invention relates to a device for laterally aligning sheets in a sheet-fed rotary printing press with a gripper system mounted axially displaceably in a cylinder, which can be displaced by an actuator which can be influenced by an evaluation unit.

Durch die DE 36 44 431 A1 ist eine derartige Vorrichtung bekannt, bei der das Greifersystem zum seitlichen Ausrichten der Bogen ständig über eine Steuerscheibe axial bei jeder Umdrehung des Zylinders verschoben wird. Abweichungen der Seitenkantenlage des Bogens werden von einer der Vorrichtung vorgeordneten Abtasteinrichtung erfasst und über einen Getriebemotor die Steuerscheibe verstellt.By DE 36 44 431 A1, such a device is known in which the gripper system for the lateral alignment of the sheet is constantly displaced axially via a control disk at each revolution of the cylinder. Deviations of the side edge position of the sheet are detected by a scanning device upstream of the device and adjusted via a geared motor, the control disk.

Nachteilig ist, dass durch Verschleiß und Verschmutzung der Steuerscheibe fehlerbehaftete Stellhandlungen initiiert werden können. Außerdem sind die Einsatzmöglichkeiten eingeschränkt, da es erforderlich ist, dass der Übergabe- und Übernahmepunkt annähernd 180° zueinander versetzt vorgesehen sind.The disadvantage is that faulty positioning actions can be initiated by wear and contamination of the control disk. In addition, the applications are limited, since it is necessary that the transfer and transfer point are provided offset approximately 180 ° to each other.

Aus der EP 0 753 407 B1 ist weiterhin eine Vorrichtung bekannt, bei der das im Zylinder in axialer Richtung verschiebbar gelagerte Greifersystem durch einen im Zylinderkanal angeordneten linearen Aktor bzw. Linearmotor verschoben werden kann.A device is also known from EP 0 753 407 B1, in which the gripper system displaceably mounted in the cylinder in the axial direction can be displaced by a linear actuator or linear motor arranged in the cylinder channel.

Nachteilig ist, dass der im Zylinderkanal gelagerte und ständig umlaufende lineare Aktor bzw. Linearmotor angesteuert werden muss.The disadvantage is that the cylinder actuator mounted in the cylinder and constantly circulating linear actuator or linear motor must be controlled.

Aufgabe der Erfindung ist die Schaffung einer weiteren gattungsgemäßen Vorrichtung zum seitlichen Ausrichten von Bogen, die eine hohe Leistung bei einem geringen Aufwand ermöglicht und universell einsetzbar ist.The object of the invention is to provide a further generic device for the lateral alignment of sheets, which enables high performance with little effort and is universally applicable.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung nach den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a device according to the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, mit einfachen Mitteln problemlos das Greifersystem zum Ausrichten von Bogen nach der Seitenkante axial zu verschieben. Außerdem ist diese Vorrichtung problemlos auch dann einzusetzen, wenn der Übernahme- und Übergabepunkt nicht gleichmäßig versetzt zueinander vorgesehen sind.By the solution according to the invention, it is possible to easily move the gripper system for aligning sheets after the side edge with simple means. In addition, this device is easy to use even if the acquisition and transfer point are not evenly offset from each other.

An einem Ausführungsbeispiel wird die Erfindung näher erläutert. In der zugehörigen Zeichnung ist ein Teil eines Zylinders 1 in einer Schnittdarstellung gezeigt. Der Zylinder 1 ist beidseitig in Seitenwänden 2 gelagert. In der Zeichnung ist nur eine Seite dargestellt. Der Zylinder 1 besteht aus einem Rohrkörper 3, einem Greifersystem 4 und einem Zylinderkörper 5. In dem Rohrkörper 3 ist konzentrisch eine Ziehschiene 6 verschiebbar in Lagerstellen 7 gelagert, die aus dem Rohrkörper 3 ragt und an diesem Ende mit einer Drehentkopplung 8 versehen ist.
Die Drehentkopplung 8 besteht aus einer drehfest mit der Ziehschiene verbundenen Hülse 9, in der gegen axiales Verschieben gesichert ein Wälzlager 10 vorgesehen ist, das ebenfalls gegen axiales Verschieben gesichert auf einer Stellwelle 11 angeordnet ist. Die Stellwelle 11 ist mit einem Stellgewinde 12 verbunden, das mit einer Motorwelle 13 eines als Stellmotor 22 ausgebildeten Stellglieds 14 in Wirkverbindung steht. Der Stellmotor 22 ist gestellfest angeordnet.
Mit der Ziehschiene 6 ist ein Mitnehmer 15 fest verbunden, der seinerseits an einer Greiferbrücke 16 des Greifersystems 4 angreift. Neben der Greiferbrücke 16 gehören zum Greifersystem 4 eine Greiferwelle 17 mit Greiferfingern 18, die mit Greiferaufschlägen 19 korrespondieren. Das Greifersystem 4 ist als funktionelle Einheit axial verschiebbar gelagert, indem an der Greiferbrücke 16 Linearführungen 20 vorgesehen sind, die in Lagerklötze 21 eingreifen, welche fest mit dem Rohrkörper 3 verbunden sind.
In one embodiment, the invention is explained in detail. In the accompanying drawing, a part of a cylinder 1 is shown in a sectional view. The cylinder 1 is mounted on both sides in side walls 2. In the drawing, only one page is shown. The cylinder 1 consists of a tubular body 3, a gripper system 4 and a cylinder body 5. In the tubular body 3 is concentrically a drawing rail 6 slidably mounted in bearings 7, which protrudes from the tubular body 3 and is provided at this end with a rotary decoupling 8.
The rotary decoupling 8 consists of a rotatably connected to the drawing rail sleeve 9, in the secured against axial displacement, a rolling bearing 10 is provided, which is also secured against axial displacement on a control shaft 11. The control shaft 11 is connected to an adjusting thread 12 which is in operative connection with a motor shaft 13 of a trained as a servomotor 22 actuator 14. The servomotor 22 is arranged fixed to the frame.
With the puller rail 6, a driver 15 is fixedly connected, which in turn acts on a gripper bar 16 of the gripper system 4. In addition to the gripper bar 16 belong to the gripper system 4, a gripper shaft 17 with gripper fingers 18 which correspond with gripper clutches 19. The gripper system 4 is mounted as a functional unit axially displaceable by 16 linear guides 20 are provided on the gripper bar, which engage in bearing pads 21, which are fixedly connected to the tubular body 3.

In an sich bekannter Weise werden Bogen in einem Bogenanleger vereinzelt und über einen Bändertisch einem Anlegtisch zugeführt. Hier werden die Bogen an Vordermarken nach der Vorderkante ausgerichtet. Durch Messmittel wird die Ist-Lage der Seitenkante erfasst und ein Messwert generiert, der einer Auswerteinheit zu einem Soll-lst-Wertvergleich zugeführt wird. Weicht der Ist-Wert von einem vorgegebenen Soll-Wert ab, wird von der Auswerteinheit ein Stellsignal erzeugt, mit dem der Stellmotor 22 angesteuert wird.In a conventional manner, sheets are singulated in a sheet feeder and fed via a belt table a feed table. Here, the bows are aligned to front marks after the leading edge. The actual position of the side edge is detected by measuring means and a measured value is generated, which is fed to an evaluation unit for a desired actual value comparison. If the actual value deviates from a predefined setpoint value, the evaluation unit generates an actuating signal with which the servomotor 22 is controlled.

Der auf dem Anlegtisch erfasste Bogen wird direkt oder mittels zusätzlicher Mittel dem Zylinder 1 zugeführt, zwischen den Greiferfingern 18 sowie den Greiferaufschlägen 19 geklemmt und in die nachgeordnete Druckmaschine gefördert. Beim Transport in die Druckmaschine wird die Ist-Lage der Bogen der Soll-Lage angepasst, indem das Greifersystem 4 axial verschoben wird.The sheet recorded on the feed table is fed directly or by means of additional means to the cylinder 1, clamped between the gripper fingers 18 and the gripper hooks 19 and conveyed to the downstream printing press. When transported to the printing press, the actual position of the sheet of the desired position is adjusted by the gripper system 4 is moved axially.

Wird dem Stellmotor 22 ein Stellsignal zugeführt, wird eine entsprechende Drehbewegung der Motorwelle 13 erzeugt, die im Stellgewinde 12 in eine axiale Stellbewegung der Stellwelle 11 umgewandelt wird. Durch diese axiale Stellbewegung wird über die Drehentkopplung 8 die mit dem Zylinder 1 umlaufende Ziehschiene 6 in axialer Richtung verschoben, damit über den Mitnehmer 15 eine axiale Stellbewegung des in den Lagerklötzen 21 verschiebbar gelagerten Greifersystems 4 und so ein Ausrichten des zwischen Greiferfingern 18 und Greiferaufschlägen 19 geklemmten Bogens realisiert.
Es ist auch möglich, das Stellglied 14 als linearen Aktor auszubilden sowie diesen direkt mit der Drehentkopplung 8 zu verbinden und so die Stellhandlungen zu realisieren.
If the adjusting motor 22 is supplied with a control signal, a corresponding rotational movement of the motor shaft 13 is generated, which is converted in the adjusting thread 12 into an axial adjusting movement of the actuating shaft 11. As a result of this axial adjusting movement, the pulling rail 6 revolving with the cylinder 1 is displaced in the axial direction via the rotary decoupling 8, thus an axial adjusting movement of the gripper system 4 displaceably mounted in the bearing blocks 21 and thus an alignment of the gripper fingers 18 and gripper hooks 19 clamped bow realized.
It is also possible to form the actuator 14 as a linear actuator and to connect it directly with the rotary decoupling 8 and so to realize the parking operations.
