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 auf einer Greiferwelle zusammengefaßt sind und auf umlaufenden Zylindern oder Trommelnangebracht sind, wobei die Greiferreihe über eine Greiferwelle, einen eine Laufrolle tragenden Antriebshebel sowie eine Steuerkurve gesteuert wird und eine Verstelleinrichtung zum Verstellung 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 gripper row on a gripper shaft and are attached to rotating cylinders or drums, the gripper row being controlled via a gripper shaft, a drive lever carrying a roller and a control cam, and an adjusting device for Has adjustment of the opening width of the gripper.

Aus den DE-AS 2 126 258 und DE-AS 2 613 174 sind Vorrichtungen zur Steuerung von Greifern in Bogenrotationsdruckmaschinen der genannten Art bekannt.From DE-AS 2 126 258 and DE-AS 2 613 174 devices for controlling grippers in sheet-fed rotary printing presses of the type mentioned are known.

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 DE-PS 834 107 ist eine Vorrichtung zur Steuerung von Greifern in Bogenrotationsdruckmaschinen mit zwei parallel zueinander angeordneten Antrieben bekannt geworden, die gemeinsam eine Torsionsfeder zur Erzeugung eines gleichen oder auch eines unterschiedlichen Spannungszustandes verdrehen und auf jeder Seite eines Druckzylinders angeordnet sind. Diese Vorrichtung betrifft eine Vorgreifersteuerung und nicht die Steuerung von Greifern eines rotierenden Zylinders. Eine Verstellung der Öffnungsweite der Greifer ist nicht möglich, so daß Passerdifferenzen auftreten.From DE-PS 834 107 a device for controlling grippers in sheet-fed rotary printing presses with two drives arranged parallel to one another has become known, which together produce a torsion spring a same or a different tension state twist and are arranged on each side of a printing cylinder. 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, so that register differences occur.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung eingangs genannter Art zu schaffen,-die es ermöglicht, an zentraler Stelle mit der erforderlichen Genauigkeit einen Kraftaufbau zum Schließen der Greifer über zwei parallele Antriebe auf unterschiedliche Bedruckstoffe einstellbar einzuleiten, um Passerdifferenzen und Doubliererscheinungen zugleich zu vermeiden.The invention has for its object to provide a device of the type mentioned, which makes it possible to initiate a force build-up at a central location with the required accuracy for closing the grippers via two parallel drives on different substrates in order to avoid register differences and doubling phenomena at the same time .

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, weil trotz erhöhter Greiferkräfte die Verspannung des Systems Greifer-Steuerkurve, Antriebshebel, Laufrolle, Steuerwelle, Greiferwelle und Verstelleinrichtung verringert wird. An zentraler Stelle erfolgt die Krafteinleitung symmetrisch zu beiden Kurvensteuerungen auf unterschiedliche Bedruckstoffe einstellbar, so daß Passerdifferenzen und Doubliererscheinungen zugleich vermieden werden.The advantages achieved by the invention are that a faster gripper closure and a shortened build-up of force are brought about because, despite increased gripper forces, the bracing of the system gripper control cam, drive lever, roller, control shaft, gripper shaft and adjusting device is reduced. At a central point, the force is applied symmetrically to both cam controls on different substrates, so that register differences and doubling phenomena are avoided at the same time.

Zur Vereinfachung sind in den Darstellungen Fig. 1 bis Fig. 5 gleiche Bauteile teilweise mit gleichen Bezugszeichen versehen. Auf einem umlaufenden Druckzylinder 8 oder einer Trommel sind eine Anzahl zumindest 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 Antiebshebeln 10, 11 und Laufrollen 12, 13 aufweist. Eine Greiferwelle'2 wird über eine zentrale Verstelleinrichtung 3, vorzugsweise eine Stellschraube mit Skala, 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.For simplification, the same components are partially provided with the same reference numerals in the illustrations in FIGS. 1 to 5. A number of at least one gripper row combined grippers 5 are mounted on a rotating pressure cylinder 8 or a drum. 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 an actuating device via a central adjusting device 3, preferably an adjusting screw with a scale Shaft 1 actuated, 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 force of both drives is introduced by 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 pretension by the spring rods 4 is 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 paral-. lel 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 Betätungswelle 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 is rotatable and parallel to one another. lel are stored 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. The position of the gripper shaft 2 is selected in accordance with the geometry of the gripper 5 in all embodiments according to FIGS. 1 to 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.
