Abstract

A device for controlling the opening of a plurality of sheet grippers in a sheet-fed rotary press wherein the grippers are arranged to form a row on a gripper shaft disposed on a rotating cylinder. The gripper shaft is centrally controlled between its ends by two cam control systems acting in parallel relationship on the ends of an actuating shaft, by turning of the latter, with a central adjusting means interconnecting the actuating shaft and the gripper shaft to provide a symmetrically divided torsional force adjustable to vary the opening width of the grippers according to the sheet thickness being processed.

Description

Die Erfindung betrifft eine Vorrichtung zur Steuerung von Greifern in Bogenrotationsdruckmaschinen, die zu einer Greiferreihe zusammengefaßt sind und auf umlaufenden Zylindern oder Trommeln angebracht sind, wobei die Greiferreihe über eine Greiferwelle und eine erste Kurvensteuerung gesteuert wird, die eine zentrale Verstelleinrichtung zum Verstellen der Öffnungsweite der Greifer aufweist.The invention relates to a device for controlling grippers in sheet-fed rotary printing presses, which are combined to form a row of grippers and are attached to rotating cylinders or drums, the row of grippers being controlled by a gripper shaft and a first cam control, which is a central adjustment device for adjusting the opening width of the grippers having.

Eine Vorrichtungen zur Steuerung von Greifern in Bogenrotationsdruckmaschinen der genannten Art ist aus der DE-B-2 613 174 bekannt.A device for controlling grippers in sheet-fed rotary printing presses of the type mentioned is known from DE-B-2 613 174.

Zur Ansteuerung der Greiferwelle ist nur ein Antrieb vorgesehen. Sollen hohe Greiferkräfte aufgebracht werden, kann es beim Schließen durch Überdrücken der stark vorgespannten Greifer zu einer Verspannung des Systems Greifer-Steuerkurve, Laufrolle, Antriebshebel, Greiferwelle, Verstelleinrichtung kommen, wodurch der Schließvorgang verzögert und der Kraftaufbau verlängert wird. Dies führt dazu, daß auch bei hohen Drehzahlen die Aufschlagkraft der Greifer nicht über die statische Haltekraft hinaus geht. Die Folge sind Doubliererscheinungen bei großer Verspannung des Systems.Only one drive is provided to control the gripper shaft. If high gripper forces are to be exerted, the gripper control cam, roller, drive lever, gripper shaft and adjustment device can become distorted by overpressing the strongly pre-tensioned grippers, which delays the closing process and increases the force build-up. This means that the impact force of the gripper does not go beyond the static holding force even at high speeds. The result is doubling when the system is very tight.

Aus der GB-A-2 080 254 ist es bekannt, eine Greiferwelle durch Betätigungswellen anzusteuern, die in einem Bogenführungszylinder parallel zu dessen Achse angeordnet sind. Der Antrieb weist aber weder eine zentrale Verstelleinrichtung zum Verstellen der Öffnungsweite der Greifer auf, noch parallel zueinander wirkende Kurvensteuerungen. Passerdifferenzen oder Doubliererscheinungen sind durch den Antrieb nicht beeinflußbar.From GB-A-2 080 254 it is known to control a gripper shaft by means of actuation shafts which are arranged in a sheet guiding cylinder parallel to its axis. However, the drive has neither a central adjusting device for adjusting the opening width of the grippers, nor cam controls acting parallel to one another. Registration differences or doubling phenomena cannot be influenced by the drive.

Aus der DE-C-834 107 ist eine Vorrichtung mit zwei parallel zueinander angeordneten Antrieben bekannt geworden, die eine Torsionsfeder zur Erzeugung eines gleichen oder auch eines unterschiedlichen Spannungszustandes verdrehen und auf jeder Seite eines Druckzylinders angeordnet sind. Diese Vorrichtung betrifft aber eine Vorgreifersteuerung und nicht die Steuerung von Greifern eines rotierenden Zylinders. Eine Verstellung der Öffnungsweite der Greifer ist nicht möglich.From DE-C-834 107 a device with two drives arranged parallel to each other has become known, which twist a torsion spring to produce an identical or a different tension state and are arranged on each side of a pressure cylinder. However, this device relates to a pre-gripper control and not to the control of grippers of a rotating cylinder. It is not possible to adjust the opening width of the grippers.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung eingangs genannter Gattung so weiterzubilden, daß unter Einbeziehung der zentralen Verstellmöglichkeit der Öffnungsweite der Greifer eine Steuerung der Greifer mit gleichmäßigem Kraftaufbau in der Greiferwelle bei der Greiferschließbewegung erreicht wird.The invention has for its object to develop a device of the type mentioned so that, taking into account the central adjustment of the opening width of the gripper, control of the gripper is achieved with uniform force build-up in the gripper shaft during the gripper closing movement.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der Zeichnung und der Beschreibung.This object is achieved by the characterizing features of patent claim 1. Further developments of the invention result from the subclaims, the drawing and the description.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß ein schnellerer Greiferschluß und ein verkürzter Kraftaufbau bewirkt werden, so daß trotz erhöhter Greiferkräfte die Verspannung des Systems Greifersteuerkurve, Laufrolle, Antriebshebel, Betätigungswelle, zentrale Verstelleinrichtung und Greiferwelle für die Öffnungsweite der Greifer verringert wird. Die Krafteinleitung erfolgt durch die als Verschraubung wirkende Stelleinrichtung symmetrisch zu beiden Kurvensteuerungen. Dadurch werden durch Verspannungen im Steuerungssystem bewirkte Passerdifferenzen und Doubliererscheinungen beseitigt. Zugleich erlaubt die als Verschraubung wirkende Stelleinrichtung 3 das stufenlose Anpassen der Öffnungsweite der Greifer, an die zu verarbeitende Bogenstärke, wodurch ebenfalls Passerdifferenzen vermieden werden.The advantages achieved by the invention are that a quicker gripper closure and a shortened build-up of force are brought about, so that, despite increased gripper forces, the bracing of the system gripper control curve, roller, drive lever, actuating shaft, central adjusting device and gripper shaft for the opening width of the grippers is reduced. The force is applied symmetrically to both cam controls by the adjusting device acting as a screw connection. This eliminates register differences and doubling effects caused by tension in the control system. At the same time, the adjusting device 3, which acts as a screw connection, allows the opening width of the grippers to be infinitely adjusted to the sheet thickness to be processed, as a result of which register differences are also avoided.

Auf einem umlaufenden Druckzylinder 8 oder einer Trommel sind eine Anzahl Z einer Greiferreihe zusammengefaßte Greifer 5 angebracht. Die Greifer 5 arbeiten mit einer Greiferauflage 9 zusammen und werden über einen Antrieb gesteuert, der zu beiden Seiten des Druckzylinders 8 oder einer Trommel je eine Kurvensteuerung 6, 7 mit Antriebshebeln 10, 11 und Laufrollen 12, 13 aufweist. Eine Greiferwelle 2 wird über eine als Verschraubung ausgebildete zentrale Verstelleinrichtung 3 von einer Betätigungswelle 1 betätigt, die formschlüssig mit den Antriebshebeln 10, 11 verbunden ist. Die Betätigungswelle 1 und die Greiferwelle 2 sind im Meßring 14 des Druckzylinders 8 oder einer Trommel gegeneinander verdrehbar gelagert. Die Greifer 5 werden mittels Federkraft durch Federstangen 4 geöffnet. Die Laufrollen 12, 13 laufen auf Stirnflächen um den Umfang der zugehörigen Steuerkurve 17, 18 herum. Die Steuerkurven 17, 18 können gleiche Kurven oder für eine Zwangssteuerung sowohl Innenkurven als auch Außenkurven aufweisen. Die Einleitung der Kraft beider Antriebe erfolgt durch die Betätigungswelle 1 über die zentrale Verstelleinrichtung 3 in der Mitte der Greiferwelle 2. Die Betätigungswelle 1 weist hierzu einen Arm 19 auf, auf dem sich eine Stellschraube mit Skala 3 abstützt, die gegen die Vorspannung durch die Federstangen 4 verdrehbar in einem Lagerarm 20 der Greiferwelle 2 zur symmetrischen Antriebsverbindung und zentralen Einstellung der Greiferöffnungsweite auf die zu verarbeitende Bogenstärke angeordnet ist. Durch die zentrale Anordnung einerseits zwischen den Kurvensteuerungen 6, 7 und andererseits zwischen Betätigungswelle 1 und Greiferwelle 2 wird die Torsionskraft symmetrisch geteilt und zugleich auf unterschiedliche Bogenstärken mit der erforderlichen Genauigkeit einstellbar. Auf diese Weise werden Doubliererscheinungen und Passerdifferenzen zugleich vermieden, weil trotz erhöhter Aufschlagkraft der Greifer das System Greifer-Steuerkurve 17, 18, Antriebshebel 10, 11, Laufrolle 12, 13, Betätigungswelle 1, Greiferwelle 2 und zentrale Verstelleinrichtung 3 durch parallele Anordnung zweier Kurvensteuerungen 6, 7 nicht mehr unzulässig verspannt wird. Durch Einbeziehung der zentralen Verstelleinrichtung 3 ist zugleich mit der erforderlichen Genauigkeit zu beiden Antrieben von einer zentralen Stelle aus die Öffnungsweise der Greifer gleichmäßig auf unterschiedliche Bedruckstoffe einstellbar.On a revolving pressure cylinder 8 or a drum a number Z of a gripper row combined grippers 5 are attached. The grippers 5 work together with a gripper support 9 and are controlled by a drive which has a cam control 6, 7 with drive levers 10, 11 and rollers 12, 13 on each side of the printing cylinder 8 or a drum. A gripper shaft 2 is actuated by a central adjusting device 3 designed as a screw connection by an actuating shaft 1 which is positively connected to the drive levers 10, 11. The actuating shaft 1 and the gripper shaft 2 are rotatably mounted in the measuring ring 14 of the pressure cylinder 8 or a drum. The grippers 5 are opened by spring rods 4. The rollers 12, 13 run on end faces around the circumference of the associated control cam 17, 18. The control curves 17, 18 can have the same curves or, for positive control, both internal curves and external curves. The introduction of the force of both drives takes place through the actuating shaft 1 via the central adjusting device 3 in the middle of the gripper shaft 2. For this purpose, the actuating shaft 1 has an arm 19 on which an adjusting screw with a scale 3 is supported, which counteracts the preload by the Spring rods 4 are rotatably arranged in a bearing arm 20 of the gripper shaft 2 for the symmetrical drive connection and central adjustment of the gripper opening width to the sheet thickness to be processed. Due to the central arrangement, on the one hand, between the cam controls 6, 7 and, on the other hand, between the actuating shaft 1 and the gripper shaft 2, the torsional force is divided symmetrically and, at the same time, can be adjusted to different arc thicknesses with the required accuracy. In this way, doubling phenomena and register differences are avoided at the same time, because despite the increased impact force of the grippers, the system gripper control cam 17, 18, drive lever 10, 11, roller 12, 13, actuating shaft 1, gripper shaft 2 and central adjustment device 3 by parallel arrangement of two cam controls 6 , 7 is no longer clamped inadmissibly. By including the central adjusting device 3, the opening of the grippers can be adjusted uniformly to different substrates with the required accuracy for both drives from a central point.

Die Betätigungswelle 1 ist als steife Torsionsfeder für einen Fertigungsfehler-Ausgleich der Kurven 17, 18 ausgebildet. Die Steuerung der Greifer 5 kann nach Fig. 1 und 2 über eine von der Greiferwelle 2 getrennte Betätigungswelle 1 erfolgen, die verdrehbar und zueinander parallel im umlaufenden Druckzylinder 8 oder einer Trommel gelagert sind. Die Steuerung der Greifer 5 kann gemäß einer anderen Ausführung nach Fig. 3 und 4 über eine von einer rohrförmigen Greiferwelle 2 konzentrisch umschlossenen Betätigungswelle 1 erfolgen. Schließlich ist gemäß einer Ausführung nach Fig. 5 die Steuerung der Greifer 5 durch die Druckzylindermitte über einen Hebeltrieb 15, 16 realisierbar. Die Lage der Greiferwelle 2 ist bei allen Ausführungen nach Fig. 1 bis Fig. 5 jeweils nach der Geometrie des Greifers 5 gewählt, während die Lage der Betätigungswelle 1 nach der günstigsten Position für die Steuerkurven 17, 18 oder die Anschlußteile 10, 11, 12, 13, 15 festliegt. Durch Wahl der Hebellänge der Antriebshebel 11 kann die Kurvenkontur günstig beeinflußt werden.The actuating shaft 1 is designed as a rigid torsion spring for compensating for manufacturing errors in the curves 17, 18. 1 and 2, the grippers 5 can be controlled via an actuating shaft 1 which is separate from the gripper shaft 2 and which are rotatable and mounted parallel to one another in the rotating pressure cylinder 8 or a drum. According to another embodiment according to FIGS. 3 and 4, the grippers 5 can be controlled via an actuating shaft 1 concentrically enclosed by a tubular gripper shaft 2. Finally, according to an embodiment according to FIG. 5, the grippers 5 can be controlled through the center of the pressure cylinder via a lever drive 15, 16. 1 to 5, the position of the gripper shaft 2 is selected according to the geometry of the gripper 5, while the position of the actuating shaft 1 according to the most favorable position for the control cams 17, 18 or the connecting parts 10, 11, 12 , 13, 15 is fixed. By choosing the lever length of the drive lever 11, the curve contour can be influenced favorably.
