Abstract

A vertically adjustable gripper support mechanism for the grippers of turning drums of perfecting presses wherein the sheet is turned by two correlatively cooperating gripper systems disposed on cam-controlled pivot shafts biased by return springs. An adjusting shaft is disposed concentrically within the pivot shaft and is rotatable by an adjusting wheel, the adjusting shaft being formed with axially spaced recesses corresponding to the number of gripper supports and having a plurality of arcuate adjusting surfaces preferably offset at 60 DEG in the peripheral direction to one another to provide a multistep vertical adjustment to the gripper support.

Description

Die Erfindung betrifft höhenverstellbare Greiferauflagen für Wendetrommelgreifer in Wendetrommeln von Schönund Widerdruckmaschinen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to height-adjustable gripper pads for reversible drum grippers in reversing drums of perfecting and reverse printing machines according to the preamble of patent claim 1.

Bei den zusammenwirkenden Greifersystemen für Schöndruck sowie für Schön- und Widerdruck einer Wendetrommel von Bogenrotationsdruckmaschinen sind die Greiferauflagen der einzelnen Greifer nicht höhenverstellbar. Derartige Greifersysteme sind z.B. in US-PS 2 757 610 und US-PS 3 385 597 beschrieben. Dadurch wird deren Einsatzbereich eingeschränkt, da dickere Papiersorten und Karton nicht paßgerecht verarbeitet werden können. ;With the interacting gripper systems for face printing as well as for front and back printing of a reversing drum of sheet-fed rotary printing presses, the gripper supports of the individual grippers cannot be adjusted in height. Such gripper systems are e.g. in U.S. Patent 2,757,610 and U.S. Patent 3,385,597. This limits their area of application, since thicker types of paper and cardboard cannot be processed to fit. ;

Allgemein ist es bekannt und z.B. in US-PS 1 208 731 und DE-PS 812 431 beschrieben, die Greiferauflagen zentral oder einzelnhöhenverstellbar für Greifersysteme von Schwinganlagen sowie für Greifersysteme, die auf einem umlaufenden Druckzylinder montiert sind, auszubilden. Diese Greifersysteme betreffen aber keine Wendetrommel. Die in den genannten Patentschriften beschriebene Verstellung mittels Ziehkeil (US-PS 1 208 731) bzw. Exzenterbuchse (DE-PS 812 431) kann zwar prinzipiell auf Wendetrommeln übertragen werden; auf Grund der baulichen und funktionellen Besonderheiten der zwei korrelativ zusammenwirkenden Greifersysteme einer Wendetrommel, insbesondere der bei großen Druckbreiten hohen Torsionsverformung der Schwenkwelle und minimaler freier Räume für die Greifersysteme, die einander gegengesetzt aufeinander zu oder voneinander weg schwingen, sind aber bisher keine Möglichkeiten bekannt'geworden, um die bekannten Höhenverstellungen in die Greifersysteme einer Wendetrommel funktionsgerecht zu integrieren.It is generally known and described, for example, in US Pat. No. 1,208,731 and DE-PS 812 431 to design the gripper pads centrally or individually height-adjustable for gripper systems of vibration systems and for gripper systems which are mounted on a rotating pressure cylinder. However, these gripper systems do not affect a turning drum. The adjustment described in the cited patents by means of a wedge (US Pat. No. 1,208,731) or an eccentric bushing (DE-PS 812 431) can in principle be transferred to turning drums; due to the structural and functional features of the two correlatively interacting gripper systems of a turning drum, in particular the high torsional deformation of the swivel shaft with large printing widths and minimal free spaces for the gripper systems that oppose each other swing towards or away from each other, but so far no possibilities have become known for functionally integrating the known height adjustments into the gripper systems of a turning drum.

Der Erfindung liegt die Aufgabe zugrunde, die Greiferauflagen für Wendetrommelgreifer in Wendetrommeln von Schönund Widerdruckmaschinen höhenverstellbar auszubilden, um den Einsatzbereich der Wendetrommeln auf alle Papierarten und Karton zu erweitern.The invention has for its object to design the gripper pads for reversible drum grippers in reversible drums of perfecting and reverse printing machines to be height-adjustable in order to expand the area of application of the reversible drums to all types of paper and cardboard.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the characterizing features of patent claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die einzelnen Greiferauflagen in gekapselter Bauweise zueinander :fluchtend, spielfrei höhenverstellbar sind, ohne daß zusätzlicher Raum für die Höhenverstellung benötigt wird und ohne daß sich die großen Torsionsverformungen der Schwenkwelle, insbesondere bei großen Druckbreiten, nachteilig auf die Genauigkeit der Einstellung auswirken können. Gerade auf diese Wirkungen kommt es bei der Höhenverstellung der Greiferauflagen für Wendetrommelgreifer in Wendetrommeln von Schönund Widerdruckmaschinen großer Druckbreite an, deren Schwenkwellen durch nockenbetätigte Hebel angetrieben werden, die von einer Seite besonders hohe Torsionskräfte unsymmetrisch einleiten.The advantages achieved by the invention are, in particular, that the individual gripper pads are encapsulated in relation to one another: aligned, play-free, height-adjustable, without additional space being required for height adjustment, and without the large torsional deformations of the swivel shaft, particularly with large pressure widths, being disadvantageous can affect the accuracy of the setting. It is precisely these effects that are important when adjusting the height of the gripper pads for reversible drum grippers in reversing drums of large and wide printing presses, the swivel shafts of which are driven by cam-actuated levers, which asymmetrically introduce particularly high torsional forces from one side.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher beschrieben.An embodiment of the invention is described below with reference to the drawings.

  • Fig. 2 einen Querschnitt durch die erfindungsgemäße Vorrichtung,
  • Fig. 3 einen Längsschnitt durch die erfindungsgemäße Vorrichtung als Ausschnitt,

Fig. 1 zeigt schematisch den Bogenlauf bei Schön- und Widerdruck für eine Bogenrotationsdruckmaschine, in der zwei Doppeldruckwerke 8 hintereinander geschaltet sind. Bei Schön- und Widerdruck wird der schon einseitig bedruckte Bogen 1 vom Greiferwagen 2 über die Zuführtrommel bzw. Sauglufttrommel 3 soweit hinweg geführt, bis sich das Bogenende in der Wendeposition befindet. In dieser Position wird nun das Bogenende vom ersten Greifersystem 4 der Wendetrommel 5 erfaßt und während dem Weitertransport an das zweite Greifersystem 6 der Wendetrommel 5 übergeben. Gleichzeitig wird der Bogen 1 vom Greiferwagen 2 noch solange geführt, bis die Greiferöffnungskurve, im Bogenabgang unten, den Bogen freigibt. Der bisherige Bogenanfang wird jetzt zum Bogenende. Während der Weiterführung des Bogens wird dieser von der Wendetrommel 5 an die Oberführungstrommel 7 übergeben. Diese führt den Bogen zum Druckzylinder des zweiten Doppeldruckwerkes 8 (nicht dargestellt), wo der Widerdruck erfolgt. Wird auf Schöndruck umgestellt, so läuft der Bogen 1 direkt von der Zuführtrommel 3 über die Wendetrommel 5, die jetzt als Zwischentrommel fungiert und anschließend über die Oberführungstrommel 7 zum zweiten Doppeldruckwerk 8. Eine Bogenübergabe innerhalb der Wendetrommel 5 gibt es nicht, da nur mit einem Greifersystem, dem Schöndrucksystem, gearbeitet wird.Fig. 1 shows schematically the sheet travel in perfecting for a sheet-fed rotary printing press in which two double printing units 8 are connected in series. In perfecting, the sheet 1, which is already printed on one side, is guided away from the gripper carriage 2 via the feed drum or suction air drum 3 until the sheet end is in the turning position. In this position, the end of the sheet is now gripped by the first gripper system 4 of the turning drum 5 and transferred to the second gripper system 6 of the turning drum 5 during further transport. At the same time, the sheet 1 is guided by the gripper carriage 2 until the gripper opening curve, in the sheet outlet below, releases the sheet. The previous beginning of the sheet now becomes the end of the sheet. During the continuation of the sheet, this is transferred from the turning drum 5 to the top guide drum 7. This leads the sheet to the printing cylinder of the second double printing unit 8 (not shown), where the reverse printing takes place. If you switch to straight printing, the sheet 1 runs directly from the feed drum 3 via the turning drum 5, which now functions as an intermediate drum and then via the top guide drum 7 to the second Double printing unit 8. There is no sheet transfer within the turning drum 5, since only one gripper system, the straight printing system, is used.

Gemäß Fig. 2 und Fig. 3 sind in bekannter Weise Wendetrommelgreifer 11 auf einer Greiferwelle 9 zusammengefaßt, die durch einen nichtdargestellten Greiferbetätigungsmechanismus ansteuerbar, in ebenfalls nicht dargestellten Greiferwellenkonsolen relativ zu einer Schwenkwelle 10 verdrehbar gelagert ist. Die Wendetrommelgreifer 11 weisen auswechselbare Greiferspitzen 12 auf, denen höhenverstellbare Greiferauflagen 13 zugeordnet sind. An der Schwenkwelle 10 ist eine Auflagenhalterung 14 befestigt, die einen abstehenden Arm 15 aufweist, der eine Rückholfeder 16 trägt, die drehbeweglich an einem Klemmstück 20 der Greiferwelle 9 befestigt ist, wobei die Rückholfeder 16 die Greiferspitzen 12 in Anlage an die höhenverstellbaren Greiferauflagen 13 drückt.According to FIGS. 2 and 3, reversible drum grippers 11 are combined in a known manner on a gripper shaft 9, which can be controlled by a gripper actuation mechanism (not shown) and is rotatably mounted in a gripper shaft bracket, also not shown, relative to a pivot shaft 10. The turning drum grippers 11 have interchangeable gripper tips 12 to which height-adjustable gripper supports 13 are assigned. A support bracket 14 is attached to the pivot shaft 10, which has a projecting arm 15 which carries a return spring 16 which is rotatably fastened to a clamping piece 20 of the gripper shaft 9, the return spring 16 pressing the gripper tips 12 into contact with the height-adjustable gripper supports 13 .

In die Schwenkwelle 10 ist eine zentrale Stellwelle 17 integriert. Die Stellwelle 17 weist für jeden Wendetrommelgreifer 11 um 60° versetzte Vertiefungen 18 in Umfangsrichtung für mindestens drei Höhenverstellungen der Greiferauflagen 13 von o,3mm, o,6mm und o,9mm auf, wodurch mittels eines zentralen Stellrades 19 durch Verdrehen der Stellwelle 17 in der Schwenkwelle 10 ein schnelles und genaues Umrüsten der Wendetrommel 5 für verschiedene Papierstärken bzw. auf Karton erfolgen kann.A central adjusting shaft 17 is integrated in the pivot shaft 10. The actuating shaft 17 has for each turning drum gripper 11 recesses 18 offset by 60 ° in the circumferential direction for at least three height adjustments of the gripper supports 13 of 0.3 mm, 6 mm and 0.9 mm, whereby a central adjusting wheel 19 rotates the setting shaft 17 in the Swivel shaft 10 a quick and accurate conversion of the turning drum 5 for different paper thicknesses or on cardboard can be done.

Die Einzelheit einer dreistufigen Stellkurve zeigt Fig. 4. Die Vertiefungen 18 der Stellwelle 17 bleiben auch bei starker Torsionsverformung der Schwenkwelle 10 auf den eingestellten Stellebenen 21, 22, 23, weil die Greiferauflagen 13 auf den Stellebenen 21, 22, 23, deren Kümmungsradius r1, r2, r3 ihren Urpsrung auf der Antriebsachse 24 der Schwenkwelle 10 haben, sich nur zentrisch verdrehen können. Hierzu werden Zapfen 26 an der Greiferauflage in Bohrungen 25 der Schwenkwelle 10 höhenverstellbar geführt und durch Federorgane 27, 28, 29, 31 spielfrei an die Stellebenen angedrückt. Im Betrieb bleibt auch bei größeren Druckbreiten und entsprechend großer Torsionsverformung der Schwenkwelle 10 die präzise eingestellte Höhe der Greiferauflagen 13 erhalten, so daß es zu keinem unterschiedlichen Schließen der Wendetrommelgreifer 11 kommt. Durch Überlagerung von Schwenkwelle 10 und Stellwelle 17 wird kein zusätzlicher Raum für die erfindungsgemäße Verstelleinrichtung benötigt. Das Federorgan 27, 28, 29 besteht aus einer Feder 27, die einen rotationssymmetrischen Teil der Greiferauflage 13 umschließt und sich zwischen einer in der Auflagenhalterung 14 an einer Platte 30 fest angeordneten Buchse 28 und einer beweglichen Buchse 29 befindet, welche gemeinsam mit der Greiferauflage 13 in der Auflagenhalterung 14 und den Bohrungen 25 der Schwenkwelle 10 gleiten kann. Jede Greiferauflage 13 ist leicht austauschbar, indem zuvor die Platte 30 entfernt wird. Ebenfalls sind die Greiferspitzen 12 einzeln leicht austauschbar.The detail of a three-stage control curve is shown in FIG. 4. The depressions 18 of the control shaft 17 remain on the set control planes 21, 22, 23 even in the event of strong torsional deformation of the pivot shaft 10, because the gripper pads 13 on the control planes 21, 22, 23, their camber radius r1, r2, r3 have their origin on the drive axis 24 of the pivot shaft 10, can only rotate centrically. For this purpose, pins 26 on the gripper support are guided in height-adjustable manner in bores 25 of the swivel shaft 10 and are pressed against the positioning planes without play by spring elements 27, 28, 29, 31. In operation, the precisely set height of the gripper supports 13 is maintained even with larger printing widths and correspondingly large torsional deformation of the pivot shaft 10, so that there is no different closing of the turning drum gripper 11. By superimposing pivot shaft 10 and adjusting shaft 17, no additional space is required for the adjusting device according to the invention. The spring member 27, 28, 29 consists of a spring 27, which encloses a rotationally symmetrical part of the gripper support 13 and is located between a bushing 28 fixed in the support holder 14 on a plate 30 and a movable bushing 29, which together with the gripper support 13 can slide in the support bracket 14 and the holes 25 of the pivot shaft 10. Each gripper pad 13 is easily interchangeable by previously removing the plate 30. The gripper tips 12 can also be easily replaced individually.

Die gekapselte Bauweise des höhenverstellbaren Greifersystems der Wendetrommel 5 verhindert eine Verschmutzung während des Betriebes und ist servicefreundlich.The encapsulated design of the height-adjustable gripper system of the turning drum 5 prevents contamination during operation and is easy to service.
