Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder nach dem Oberbegriff der Patentansprüche 1 und 8.The present invention relates to a device for adjusting the jaws on a jaw cylinder according to the preamble of claims 1 and 8.

Aus der DE-PS 25 37 920 B2 ist ein Falzzylinder bekannt, der wenigstens eine am Umfang angeordnete feste Falzleiste und wenigstens eine damit zusammenwirkende gesteuerte Falzklappe aufweist, deren Arbeitsabstand durch gegenläufiges Verstellen von Falzleiste und Falzklappe einstellbar ist. Zu diesem Zweck ist die gesteuerte Falzklappe exzentrisch in einem die feste Falzleiste haltenden, mittels einer Stelleinrichtung verdrehbaren Träger schwenkbar gelagert und mittels einer Torsionsfeder drehelastisch mit dem Träger des Falzzylinders verbunden. Der Träger ist mit einem an einer Lasche des Trägers angreifenden Hebel, der mittels eines in einer koaxialen Ausnehmung der Zylinderachse verschiebbaren, eine schiefe Ebene aufweisenden Gleitstücks in radialer Richtung verstellbar ist, gelenkig verbunden. Das Gleitstück ist über ein Axiallager mit einer in Drehrichtung feststehenden und axial mittels eines Stellmittels, wie z.B. eines Handrads, bewegbaren Spindel verbunden.From DE-PS 25 37 920 B2 a folding cylinder is known which has at least one fixed folding strip arranged on the circumference and at least one cooperating controlled folding flap, the working distance of which can be adjusted by opposing adjustment of the folding strip and folding flap. For this purpose, the controlled folding flap is pivotally mounted eccentrically in a carrier holding the fixed folding strip, which can be rotated by means of an adjusting device, and is connected in a torsionally elastic manner to the carrier of the folding cylinder by means of a torsion spring. The carrier is connected in an articulated manner to a lever which engages on a tab of the carrier and which is adjustable in the radial direction by means of a slider which is displaceable in a coaxial recess of the cylinder axis and has an inclined plane. The slider is an axial bearing with a fixed in the direction of rotation and axially by means of an actuator such as a handwheel, movable spindle connected.

Bei dem bekannten Falzzylinder ist ein Verstellen der Falzklappen während der Rotation des Zylinders möglich. Die verstellbare Falzklappe und die feste Falzleiste führen dabei eine gleichzeitige zangenartige Verstellbewegung aus. Nachteilig ist an diesem bekannten Falzzylinder jedoch, daß diese Verstellbewegung über einen mehrteiligen Hebel erfolgt und daß für jedes aus einer gesteuerten Falzklappe und einer festen Falzleiste gebildete Falzklappenpaar ein solcher Hebel erforderlich ist. Nachteilig ist ebenfalls, daß dieser Hebel mit seinem einen Ende auf einer schiefen Ebene läuft, deren Steigung zur Erzielung einer Selbsthemmung geringer ist als die dem Reibungskoeffizienten entsprechende Steigung. Die somit gegebene Vielzahl von für das Verstellen aller Falzklappen des Falzzylinders erforderlichen Teile und die durch die Reibung insbesondere des Hebels auf der schiefen Ebene verursachte Abnutzung bedeuten einen hohen Aufwand bei Montage und Justierung des Falzzylinders, um eine spielfreie Übertragung der Verstellkräfte zu erreichen, und eine hohe Betriebsunsicherheit durch hohen Verschleiß der Verstellvorrichtung. Dabei wird der Verschleiß noch dadurch erhöht, daß bei der Verstellvorrichtung des bekannten Falzzylinders immer wieder die gleichen Stellen belastet werden und daß die Steuerung der Klappen nur an einer Zylinderseite erfolgt.In the known folding cylinder, an adjustment of the folding flaps is possible during the rotation of the cylinder. The adjustable folding flap and the fixed folding strip perform a simultaneous pliers-like adjustment movement. A disadvantage of this known folding cylinder, however, is that this adjustment movement takes place via a multi-part lever and that such a lever is required for each pair of folding jaws formed from a controlled folding jaw and a fixed folding ledge. Another disadvantage is that this lever runs with its one end on an inclined plane, the slope of which is less to achieve self-locking than the slope corresponding to the coefficient of friction. The thus Given the large number of parts required for the adjustment of all folding jaws of the folding cylinder and the wear caused by the friction, in particular of the lever, on the inclined plane mean a great deal of effort when assembling and adjusting the folding cylinder in order to achieve a play-free transmission of the adjusting forces and a high level of operational uncertainty due to high wear of the adjustment device. The wear is further increased by the fact that the adjusting points of the known folding cylinder are repeatedly loaded at the same points and that the flaps are only controlled on one side of the cylinder.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder so auszubilden, daß Zusammenbau und Justierung der Vorrichtung wesentlich vereinfacht werden und daß der Verschleiß wesentlich reduziert und von der Anzahl der zu steuernden Klappenpaare unabhängig wird.The object of the present invention is therefore to design a device for adjusting the jaws on a jaw cylinder so that assembly and adjustment of the device are considerably simplified and that the wear is significantly reduced and is independent of the number of flap pairs to be controlled.

Diese Aufgabe wird durch Vorrichtungen zum Verstellen der Falzklappen an einem Falzklappenzylinder mit den Merkmalen der Patentansprüche 1 bzw. 8 gelöst.This object is achieved by devices for adjusting the jaws on a jaw cylinder with the features of claims 1 and 8, respectively.

Fig. 1 zeigt in einer stark schematisierten Darstellung eine Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder in einer ersten erfindungsgemäßen Ausführungsform. Der Falzklappenzylinder 1 weist eine Falzklappenzylinderachse 2 und zwei darauf koaxial ineinanderliegend und in einem Winkelbereich um die Falzklappenzylinderachse 2 schwenkbar angeordnete, mit Falzklappenpaaren 3 versehene im wesentlichen zylinderförmige Falzklappenkörper 6 und 7 auf. Während am Falzklappenkörper 6 eine Mehrzahl steuerbarer Falzklappen 4 angebracht ist, ist am Falzklappenkörper 7 eine Mehrzahl fester Falzklappen 5 angebracht. Je eine steuerbare Falzklappe 4 und je eine feste Falzklappe 5 bilden ein Falzklappenpaar 3. Die Steuerung der Falzklappen 4 während des Falzvorgangs an dem sich dann drehenden Falzklappenzylinder 1 erfolgt in an sich bekannter und für die vorliegende Erfindung nicht wesentlicher Weise mittels einer auf einer Kurvenscheibe ablaufenden Steuerrolle (beide nicht dargestellt).Fig. 1 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a first embodiment according to the invention. The jaw cylinder 1 has a jaw cylinder axis 2 and two essentially cylindrical jaw bodies 6 and 7, which are arranged coaxially one inside the other and pivotable in an angular range around the jaw cylinder axis 2 and provided with jaw pairs 3. While a plurality of controllable jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7. A controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3. The control of the folding jaws 4 during the folding process on the then rotating jaw cylinder 1 is carried out in a manner known per se and not essential for the present invention by means of a running on a cam disc Control role (both not shown).

Die Anordnung der Falzklappenpaare 3 im Falzklappenzylinder 1 ist in Fig. 3 beispielhaft für ein einziges Falzklappenpaar 3 dargestellt. Dabei ist die für das Steuern der Falzklappe 4 erforderliche Vorrichtung symbolisch durch einen Hebel 40 dargestellt.The arrangement of the pairs of jaws 3 in the jaw cylinder 1 is shown in FIG. 3 as an example for a single pair of jaws 3. The device required for controlling the folding jaw 4 is symbolically represented by a lever 40.

Für den Antrieb des Falzklappenzylinders 1 ist auf der Falzklappenzylinderachse 2 ein erstes Zahnrad 8 fest angebracht. Das Zahnrad 8 ist über einen Zahnradblock 13, der wenigstens zwei mit einer äußeren Verzahnung versehene Zahnkränze 31 und 32 aufweist, mit einem auf der Zylinderachse 2 koaxial und gegenüber der Falzklappenzylinderachse 2 drehbar angeordneten zweiten Zahnrad 9 verbunden. Das Zahnrad 9 und der Falzklappenkörper 6 sind durch eine auf der Falzklappenzylinderachse 2 koaxial und gegenüber dieser drehbar angebrachte erste Flanschbüchse 15 fest miteinander verbunden. Durch diese Anordnung werden die steuerbaren Falzklappen 4 zum Zahnrad 8 synchron angetrieben. Die Flanschbüchse 15 ist an ihrem dem Zahnrad 8 abgewandten Ende bundartig ausgebildet und mit einem zur Falzklappenzylinderachse 2 koaxial angeordneten dritten Zahnrad 10 fest verbunden, das mit einem Drehrichtungsumkehrgetriebe 14 in Eingriff steht. Das Drehrichtungsumkehrgetriebe 14 weist ein mit der Falzklappenzylinderachse 2 fest verbundenes Gestell 14′ auf, an dem eine für die vorliegende Erfindung nur hinsichtlich ihrer Gesamtwirkung wesentliche Mehrzahl von Zahnrädern drehbar gelagert ist: Das Drehrichtungsumkehrgetriebe 14 überträgt beim Verstellen der Falzklappen die relative Drehbewegung des Falzklappenkörpers 6 gegenüber der Falzklappenzylinderachse 2 im Verhältnis 1:1 und mit gleichzeitiger Drehrichtungsumkehr auf den Falzklappenkörper 7.For driving the jaw cylinder 1, a first gear 8 is fixedly mounted on the jaw cylinder axis 2. The Gear 8 is connected via a gear block 13, which has at least two toothed rings 31 and 32 provided with external teeth, to a second gear 9 arranged coaxially on the cylinder axis 2 and rotatable with respect to the jaw cylinder axis 2. The gear wheel 9 and the jaw body 6 are firmly connected to one another by a first flange sleeve 15 which is coaxially mounted on the jaw cylinder axis 2 and rotatable relative thereto. With this arrangement, the controllable jaws 4 are driven synchronously with the gear 8. The flange bushing 15 is formed like a collar at its end facing away from the gear 8 and is fixedly connected to a third gear 10 which is arranged coaxially with the jaw cylinder axis 2 and which engages with a reversing gear 14. The direction of rotation reversal gear 14 has a frame 14 'which is fixedly connected to the jaw cylinder axis 2 and on which a plurality of gearwheels, which is essential for the present invention only with regard to its overall effect, is rotatably mounted of the jaw cylinder axis 2 in a ratio of 1: 1 and with simultaneous reversal of the direction of rotation on the jaw body 7.

Der Falzklappenkörper 7 weist an seinen beiden Stirnseiten jeweils einen bundartig ausgeführten Flansch 71 bzw. 72 auf. Der Flansch 71 ist abschnittweise oder vollständig mit einer Außenverzahnung 11 versehen, die mit dem Drehrichtungsumkehrgetriebe 14 in Eingriff steht, während der Flansch 72 mit einer Außenverzahnung 18 versehen ist. Um eine parallele Verstellung der Falzklappen 4 und 5 zu gewährleisten, kann am Flansch 72 ein dem Drehrichtungsumkehrgetriebe 14 gleiches, diesem gegenüber spiegelbildlich angeordnetes zusätzliches Drehrichtungsumkehrgetriebe 114 vorgesehen werden, das ein mit der Falzklappenzylinderachse 2 fest verbundenes Gestell 114′ aufweist. Das Drehrichtungsumkehrgetriebe 114 steht mit der Außenverzahnung 18 und einem am Falzklappenkörper 6 angebrachten Zahnrad 10′ in Eingriff und verbindet so die beiden Falzklappenkörper 6 und 7.The jaw body 7 has a flange 71 and 72, respectively, on its two end faces. The flange 71 is partially or completely provided with an external toothing 11, which is in engagement with the reversing gear 14, while the flange 72 is provided with an external toothing 18. In order to ensure a parallel adjustment of the jaws 4 and 5, the same can be provided on the flange 72 the reversing gear 14, this opposite mirror-image arranged additional reversing gear 114, which has a frame 114 'fixedly connected to the jaw cylinder axis 2. The direction of rotation reversal gear 114 is in engagement with the external toothing 18 and a gear 10 'attached to the jaw body 6 and thus connects the two jaw bodies 6 and 7.

Der Zahnradblock 13 weist einen im wesentlichen hohlzylindrischen, mit einem Innengewinde 23 zur Aufnahme eines Stellelements 25 versehenen Trägerkörper 24 auf, der auf einem Zapfen 33 axial verschiebbar angeordnet und gegen Verdrehen gesichert ist. Auf dem Trägerkörper 24 sind die wenigstens zwei Zahnkränze 31 und 32 koaxial und drehbar angeordnet.The gear block 13 has an essentially hollow cylindrical support body 24, which is provided with an internal thread 23 for receiving an actuating element 25 and is axially displaceably arranged on a pin 33 and secured against rotation. The at least two ring gears 31 and 32 are arranged coaxially and rotatably on the carrier body 24.

Der Trägerkörper 24 ist über das Innengewinde 23 mit einer als Stellelement dienenden Gewindespindel 25 drehbar verbunden. Die Gewindespindel 25 wird von einer steuerbaren, eine Fernverstellung der Falzklappen ermöglichenden motorischen Antriebsvorrichtung 30 mit Rückmeldung über Potentiometer angetrieben. Ein Antreiben der Gewindespindel 25 bewirkt eine axiale Verschiebung des Zahnradblocks 13, was aufgrund der Kombination der Verzahnungen der Zahnkränze 31 und 32 und der Zahnräder 8 und 9 ein Verdrehen des Zahnrads 9 gegenüber dem Zahnrad 8 ergibt. Gleichzeitig ergibt die durch das Drehrichtungsumkehrgetriebe 14 und gegebenenfalls auch durch das zusätzliche Drehrichtungsumkehrgetriebe 114 bewirkte Richtungsumkehr ein Verstellen des Falzklappenkörpers 7 in entgegengesetzter Richtung. Zusammen ergeben diese Verstellbewegungen eine gleichzeitige zangenartige Verstellbewegung je einer steuerbaren Falzklappe 4 und einer zugehörigen festen Falzklappe 5, so daß ein Nachführen der Falzmesser eines mit dem Falzklappenzylinder 1 zusammenwirkenden Falzmesserzylinders 200 nicht erforderlich ist.The carrier body 24 is rotatably connected via the internal thread 23 to a threaded spindle 25 serving as an actuating element. The threaded spindle 25 is driven by a controllable motor drive device 30, which enables remote adjustment of the folding jaws, with feedback via potentiometers. Driving the threaded spindle 25 causes an axial displacement of the gear block 13, which results in a rotation of the gear 9 relative to the gear 8 due to the combination of the teeth of the ring gears 31 and 32 and the gears 8 and 9. At the same time, the reversal of direction caused by the reversing gear 14 and possibly also by the additional reversing gear 114 results in an adjustment of the jaw body 7 in the opposite direction. Together, these adjustment movements result in a simultaneous forceps-like adjustment movement, each of a controllable folding jaw 4 and an associated fixed folding jaw 5, so that it is not necessary to readjust the folding blades of a folding blade cylinder 200 interacting with the folding jaw cylinder 1.

In einer vorteilhaften Weiterbildung der Erfindung kann für den Antrieb der Gewindespindel 25 auch ein Handrad 29 vorgesehen werden, wie dies im Zusammenhang mit dem zweiten Ausführungsbeispiel näher beschrieben und in Fig. 2 dargestellt ist.In an advantageous development of the invention, a handwheel 29 can also be provided for driving the threaded spindle 25, as described in more detail in connection with the second exemplary embodiment and shown in FIG. 2.

Fig. 2 zeigt in einer stark schematisierten Darstellung eine Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder in einer erfindungsgemäßen zweiten Ausführungsform. Der in Fig. 2 dargestellte Falzklappenzylinder 1 weist eine Falzklappenzylinderachse 2 und zwei darauf koaxial ineinanderliegend und in einem Winkelbereich um die Falzklappenzylinderachse 2 schwenkbar angeordnete, mit Falzklappenpaaren 3 versehene Falzklappenkörper 6 und 7 auf. Während am Falzklappenkörper 6 eine Mehrzahl steuerbarer Falzklappen 4 angebracht ist, ist am Falzklappenkörper 7 eine Mehrzahl fester Falzklappen 5 angebracht. Je eine steuerbare Falzklappe 4 und je eine feste Falzklappe 5 bilden ein Falzklappenpaar 3. Die Anordnung der Falzklappenpaare 3 im Falzklappenzylinder 1 ist in Fig. 3 beispielhaft für ein einziges Falzklappenpaar 3 dargestellt.Fig. 2 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a second embodiment according to the invention. The jaw cylinder 1 shown in Fig. 2 has a jaw cylinder axis 2 and two coaxially one on top of the other and in an angular range around that The jaw cylinder axis 2 has pivot jaw bodies 6 and 7 which are pivotally arranged and provided with jaw pairs 3. While a plurality of controllable jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7. A controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3. The arrangement of the jaws 3 in the jaw cylinder 1 is shown in FIG. 3 as an example for a single jaw pair 3.

Die Falzklappenzylinderachse 2 ist mit einem auf ihr koaxial angebrachten vierten Zahnrad 108 fest verbunden. Weiterhin sind auf der Falzklappenzylinderachse 2 ein fünftes Zahnrad 109 und ein sechstes Zahnrad 110 koaxial und verdrehbar angeordnet. Das fünfte Zahnrad 109 ist über eine zweite Flanschbüchse 16, die die Zylinderachse 2 umfaßt und auf dieser drehbar gelagert ist, mit dem Falzklappenkörper 7 fest verbunden. Das sechste Zahnrad 110 ist über eine dritte Flanschbüchse 17, die die zweite Flanschbüchse 16 umschließt und gegenüber dieser verdrehbar ist, mit dem Falzklappenkörper 6 fest verbunden. Während das vierte Zahnrad 108 gerade verzahnt ist, sind das fünfte Zahnrad 109 und das sechste Zahnrad 110 gegenläufig schräg verzahnt. Die Zahnräder 108, 109 und 110 stehen mit einem Getriebe 112 in Eingriff. Das Getriebe 112 weist eine Ritzelwelle 119, ein erstes Ritzel 120, ein zweites Ritzel 121 und ein drittes Ritzel 122 auf. Während das erste Ritzel 120 gerade verzahnt ist, sind das zweite Ritzel 121 und das dritte Ritzel 122 gegenläufig schrägverzahnt, und zwar so, daß die jeweilige Steigungsrichtung des zweiten Ritzels 121 bzw. des dritten Ritzels 122 der jeweiligen Steigungsrichtung des Zahnrads 109 bzw. des Zahnrads 110, mit denen die beiden Ritzel 121 und 122 in Eingriff sind, entgegengerichtet ist. Die Zahnräder 108, 109 und 110 wirken mit den Ritzeln 120, 121 und 122 derart zusammen, daß ein Verdrehen des Zahnrads 109 gegenüber dem Zahnrad 108 in eine entgegengerichtete Verdrehung des Zahnrads 110 umgesetzt wird.The jaw cylinder axis 2 is firmly connected to a fourth gear 108 coaxially mounted on it. Furthermore, a fifth gear 109 and a sixth gear 110 are arranged coaxially and rotatably on the jaw cylinder axis 2. The fifth gear 109 is fixedly connected to the jaw body 7 via a second flange sleeve 16, which comprises the cylinder axis 2 and is rotatably mounted thereon. The sixth gearwheel 110 is fixedly connected to the jaw body 6 via a third flange sleeve 17, which surrounds the second flange sleeve 16 and can be rotated relative to the latter. While the fourth gear 108 is currently toothed, the fifth gear 109 and the sixth gear 110 are helically toothed in opposite directions. The gears 108, 109 and 110 mesh with a gear 112. The transmission 112 has a pinion shaft 119, a first pinion 120, a second pinion 121 and a third pinion 122. While the first pinion 120 is straight-toothed, the second pinion 121 and the third pinion 122 are helically toothed in opposite directions, in such a way that the respective pitch direction of the second pinion 121 and the third pinion 122 corresponds to the respective pitch direction of the gear 109 and the gear 110, with which the two pinions 121 and 122 are engaged, is directed in the opposite direction. The gear wheels 108, 109 and 110 interact with the pinions 120, 121 and 122 in such a way that a rotation of the gear wheel 109 relative to the gear wheel 108 is converted into an opposite rotation of the gear wheel 110.

Das Getriebe 112 ist mittels einer Halterung 126 mit einer als Stellelement dienenden Gewindespindel 125 drehbar verbunden. Die Gewindespindel 125 ist in einer Trägerplatte 127 mit angrenzendem Gewindeteil 128 und in einem Gegenlager 133 drehbar gelagert und an dem der Halterung 126 abgewandten Ende mit einem Handrad 29 fest verbunden. Bei Betätigung des Handrades 29 wird die Gewindespindel 125 zusammen mit der Halterung 126 gedreht, wodurch das Getriebe 112 in axialer Richtung verstellt wird. Die axiale Verstellung des Getriebes 112 ergibt aufgrund der Kombination der verschiedenen Verzahnungen der Ritzel 120 bis 122 und der Zahnräder 108 bis 110 eine relative Drehung des Zahnrads 109 gegenüber dem Zahnrad 108 in der einen Richtung und eine relative Drehung des Zahnrads 110 gegenüber dem Zahnrad 108 in entgegengesetzter Richtung. Diese Verstellbewegungen ergeben zusammen eine gleichzeitige zangenartige Verstellbewegung je einer steuerbaren Falzklappe 4 und einer zugehörigen festen Falzklappe 5, so daß ein Nachführen der Falzmesser eines mit dem Falzklappenzylinder 1 zusammenwirkenden Falzmesserzylinders 200 nicht erforderlich ist.The gear 112 is rotatably connected to a threaded spindle 125 serving as an actuating element by means of a holder 126. The Threaded spindle 125 is rotatably mounted in a carrier plate 127 with an adjacent threaded part 128 and in a counter bearing 133 and is fixedly connected to a handwheel 29 at the end facing away from the holder 126. When the handwheel 29 is actuated, the threaded spindle 125 is rotated together with the holder 126, as a result of which the gear 112 is adjusted in the axial direction. The axial displacement of the gear 112 results in a relative rotation of the gear 109 relative to the gear 108 in one direction and a relative rotation of the gear 110 relative to the gear 108 due to the combination of the different toothings of the pinions 120 to 122 and the gear wheels 108 to 110 opposite direction. These adjustment movements together result in a simultaneous forceps-like adjustment movement each of a controllable folding jaw 4 and an associated fixed folding jaw 5, so that it is not necessary to readjust the folding blades of a folding blade cylinder 200 interacting with the folding jaw cylinder 1.

In einer vorteilhaften Weiterbildung der Erfindung kann für den Antrieb der Gewindespindel 125 auch eine steuerbare motorische Antriebsvorrichtung 30 vorgesehen werden, wie dies im Zusammenhang mit dem ersten Ausführungsbeispiel näher beschrieben und in Fig. 1 dargestellt ist.In an advantageous development of the invention, a controllable motor drive device 30 can also be provided for driving the threaded spindle 125, as is described in more detail in connection with the first exemplary embodiment and is shown in FIG. 1.

Fig. 4 zeigt in einer stark schematisierten Darstellung eine Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder in einer dritten erfindungsgemäßen Ausführungsform. Der Falzklappenzylinder 1 weist eine Falzklappenzylinderachse 2 und zwei darauf koaxial ineinanderliegend und in einem Winkelbereich um die Falzklappenzylinderachse 2 schwenkbar angeordnete, mit Falzklappenpaaren 3 versehene und im wesentlichen zylinderförmige Falzklappenkörper 6 und 7 auf. Während am Falzklappenkörper 6 eine Mehrzahl steuerbarer Falzklappen 4 angebracht ist, ist am Falzklappenkörper 7 eine Mehrzahl fester Falzklappen 5 angebracht. Je eine steuerbare Falzklappe 4 und je eine feste Falzklappe 5 bilden ein Falzklappenpaar 3, wie dies bereits anhand der Figur 3 für die ersten beiden Ausführungsbeispiele erläutert wurde. Die Steuerung der Falzklappen 4 während des Falzvorgangs an dem sich dann drehenden Falzklappenzylinder 1 erfolgt in an sich bekannter und für die vorliegende Erfindung nicht wesentlicher Weise mittels einer auf einer Kurvenscheibe ablaufenden Steuerrolle (beide nicht dargestellt).Fig. 4 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a third embodiment of the invention. The jaw cylinder 1 has a jaw cylinder axis 2 and two coaxially one inside the other and pivotably arranged in an angular range around the jaw cylinder axis 2, provided with jaw pairs 3 and essentially cylindrical jaw bodies 6 and 7. While a plurality of controllable jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7. A controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3, as has already been done with reference to FIG. 3 for the first two Exemplary embodiments have been explained. The control of the jaws 4 during the folding process on the then rotating jaw cylinder 1 takes place in a manner known per se and not essential for the present invention by means of a control roller running on a cam (both not shown).

Für den Antrieb des Falzklappenzylinders 1 ist auf der Falzklappenzylinderachse 2 ein siebentes Zahnrad 308 fest angebracht. Das Zahnrad 308 ist über einen Zahnradblock 313, der wenigstens zwei mit einer äußeren Verzahnung versehene Zahnkränze 331 und 332 aufweist, mit einem auf der Falzklappenzylinderachse 2 koaxial und gegenüber dieser drehbar angeordneten achten Zahnrad 309 verbunden. Das Zahnrad 309 und der Falzklappenkörper 6 sind über einen Getriebezug, der sich aus einer auf der Falzklappenzylinderachse 2 koaxial und gegenüber dieser drehbar angebrachten vierten Flanschbüchse 315, die an ihrem dem Zahnrad 308 abgewandten Ende bundartig ausgebildet ist, einem zur Falzklappenzylinderachse 2 koaxial angeordneten neunten Zahnrad 310, das mit dem bundartig ausgebildeten Ende der Flanschbüchse 315 fest verbunden ist, einem mit dem Zahnrad 310 in Eingriff stehenden ersten Zahnelement 303 und einer ersten Spindel 301, die in dem Falzklappenkörper 6 achsparallel zur Falzklappenzylinderachse 2 drehbar gelagert ist und auf der das Zahnelement 303 fest angebracht ist, zusammensetzt, verbunden.For driving the jaw cylinder 1, a seventh gear 308 is fixedly mounted on the jaw cylinder axis 2. The gearwheel 308 is connected via a gearwheel block 313, which has at least two toothed rings 331 and 332 provided with external teeth, to an eighth gearwheel 309 which is arranged coaxially on the jaw cylinder axis 2 and rotatable relative thereto. The gearwheel 309 and the jaw body 6 are, via a gear train, which consists of a fourth flange bushing 315, which is coaxially mounted on the jaw cylinder axis 2 and rotatable relative to the latter, and which is configured like a collar at its end remote from the gear wheel 308, a ninth gearwheel arranged coaxially with the jaw cylinder axis 2 310, which is fixedly connected to the collar-shaped end of the flange sleeve 315, a first tooth element 303 which engages with the gearwheel 310 and a first spindle 301 which is rotatably mounted in the jaw body 6 in an axis-parallel manner to the jaw cylinder axis 2 and on which the tooth element 303 is firmly attached, assembled, connected.

Das erste Zahnelement 303 und ein zehntes Zahnrad 302, das auf der Spindel 301 koaxial fest angebracht ist, bilden zusammen mit einer zweiten Spindel 304, die in dem Falzklappenkörper 7 achsparallel zur Falzklappenzylinderachse 2 drehbar gelagert ist, und einem elften Zahnrad 305 und einem zweiten Zahnelement 306, die beide auf der Spindel 304 fest angebracht sind und in ihrer Ausbildung dem Zahnrad 302 bzw. dem Zahnelement 303 entsprechen, einen Teil eines Drehrichtungsumkehrgetriebes 314, das mit dem Zahnrad 310 in Eingriff steht. Das Drehrichtungsumkehrgetriebe 314 weist außerdem ein mit der Falzklappenzylinderachse 2 fest verbundenes Gestell 320 auf, an dem ein im wesentlichen kreissegmentförmiges drittes Zahnelement 311 mit einem Innenwälzkreis und ein im wesentlichen kreissegmentförmiges viertes Zahnelement 312 mit einem Außenwälzkreis fest angebracht sind. Während das Zahnelement 311 mit dem Zahnrad 302 kraft- oder formschlüssig abwälzbar verbunden ist, ist das Zahnelement 312 mit dem Zahnrad 305 kraft- oder formschlüssig abwälzbar verbunden. Ferner weist das Gestell 320 ein Langloch 321 auf, durch das die Spindel 301 berührungsfrei hindurchgeführt ist.The first tooth element 303 and a tenth gear wheel 302, which is fixed coaxially on the spindle 301, form together with a second spindle 304, which is rotatably mounted in the jaw body 7 in an axis-parallel manner to the jaw cylinder axis 2, and an eleventh gear wheel 305 and a second tooth element 306, both of which are fixedly mounted on the spindle 304 and correspond in their design to the gear wheel 302 or the tooth element 303, part of a reversing gear 314, which is in engagement with the gear wheel 310. The reversing gear 314 also has a frame 320 which is fixedly connected to the jaw cylinder axis 2 on which an essentially circular segment-shaped third tooth element 311 with an internal rolling circle and an essentially circular segment-shaped fourth tooth element 312 with an external rolling circle are fixedly attached. While the tooth element 311 is connected to the gear wheel 302 in a non-positive or positive manner, the tooth element 312 is connected to the gear wheel 305 in a non-positive or positive manner. Furthermore, the frame 320 has an elongated hole 321 through which the spindle 301 is passed without contact.

Das Drehrichtungsumkehrgetriebe 314 überträgt beim Verstellen der Falzklappen die relative Drehbewegung des Zahnrads 309 gegenüber dem Zahnrad 308 durch Abwälzen des Zahnrads 302 auf dem Zahnelement 311, wodurch die Spindel 301 in Umfangsrichtung des Falzklappenkörpers 6 bewegt wird, und durch Abwälzen des Zahnrads 305 auf dem Zahnelement 312, wodurch die Spindel 304 in Umfangsrichtung des Falzklappenkörpers 7 bewegt wird, gleichzeitig und im gleichen Gesamtübersetzungsverhältnis, aber mit zueinander entgegengesetzter Drehrichtung, auf die Falzklappenkörper 6 und 7. Damit erfolgt eine gleichzeitige und zum jeweiligen Falzmesser symmetrische Verstellung aller Falzklappenpaare 3 des Falzklappenzylinders 1.The direction of rotation reversal gear 314 transmits the relative rotary movement of the gear 309 relative to the gear 308 by rolling the gear 302 on the tooth element 311 when the jaws are adjusted, whereby the spindle 301 is moved in the circumferential direction of the jaw body 6, and by rolling the gear 305 on the tooth element 312 , whereby the spindle 304 is moved in the circumferential direction of the jaw body 7, simultaneously and in the same overall transmission ratio, but with the opposite direction of rotation, onto the jaw bodies 6 and 7. This results in a simultaneous adjustment of all jaw pairs 3 of the jaw cylinder 1 that is symmetrical to the respective jaw knife.

Figur 5 zeigt in einer stark vereinfachten Darstellung eine axiale Ansicht der Anordnung der wesentlichen Elemente des im dritten Ausführungsbeispiel beschriebenen Drehrichtungsumkehrgetriebes 314. In dieser Darstellung sind insbesondere die mit dem Zahnrad 310 in Eingriff stehenden Zahnelemente 303 und 306, sowie die Zahnräder 302 und 305, die mit den Zahnelementen 311 bzw. 312 in Eingriff stehen, zu erkennen. Weiterhin ist deutlich sichtbar, wie die Drehbewegung des Zahnrads 310 durch die sich auf ihm abwälzenden Zahnelemente 303 und 306 in eine gleichgerichtete Drehbewegung der Zahnräder 302 und 305 umgesetzt wird und wie die Drehbewegung dieser beiden Zahnräder aufgrund des Abwälzens des einen Zahnrads auf einem Zahnelement mit Innenwälzkreis und aufgrund des Abwälzens des anderen Zahnrads auf einem Zahnelement mit Außenwälzkreis in die zueinander entgegengesetzt gerichteten Drehbewegungen der Falzklappenkörper 6 und 7 umgesetzt wird.FIG. 5 shows a highly simplified illustration of an axial view of the arrangement of the essential elements of the reversing gear 314 described in the third exemplary embodiment are in engagement with the tooth elements 311 and 312, respectively. Furthermore, it is clearly visible how the rotational movement of the gear 310 is converted into a rectified rotational movement of the gears 302 and 305 by the gear elements 303 and 306 rolling on it and how the rotational movement of these two gears due to the rolling of one gear on a gear element with an internal pitch circle and due to the rolling of the other gear on a tooth element with an external rolling circle in the mutually opposite rotational movements of the jaw bodies 6 and 7 is implemented.

In einer vorteilhaften Weiterbildung der Erfindung kann für den Antrieb der Gewindespindel 325 ein Handrad 29, wie dies im Zusammenhang mit dem zweiten Ausführungsbeispiel näher beschrieben und in Fig. 2 dargestellt ist, eine steuerbare motorische Antriebsvorrichtung 30, wie dies im Zusammenhang mit dem ersten Ausführungsbeispiel näher beschrieben und in Fig. 1 dargestellt ist, oder jede andere zweckmäßige, nicht notwendigerweise ständig mit der Gewindespindel 325 verbundene Antriebsvorrichtung vorgesehen sein.In an advantageous development of the invention, a handwheel 29, as described in more detail in connection with the second exemplary embodiment and shown in FIG. 2, a controllable motor drive device 30, as described in more detail in connection with the first exemplary embodiment, can be used to drive the threaded spindle 325 described and shown in Fig. 1, or any other appropriate, not necessarily permanently connected to the threaded spindle 325 drive device.

Die Vorrichtung zum Verstellen der Falzklappen an einem Falzklappenzylinder weist, wie dies vorstehend an drei Ausführungsbeispielen erläutert worden ist, folgende Vorteile auf:

  • die die Verstellbewegung übertragenden Getriebe weisen kein zur Selbsthemmung durch Reibung ausgelegtes Teil auf;
  • die Vorrichtung weist für die Gesamtheit der Falzklappenpaare ein einziges Getriebe bzw. eine wie ein einziges Getriebe wirkende Kombination aus einem Zahnradblock und einem Drehrichtungsumkehrgetriebe auf;
  • durch die Verwendung von umlaufenden Teilen wird eine Konzentration der Belastung auf einzelne Stellen der Vorrichtung vermieden;
  • die erfindungsgemäße Stellvorrichtung wird unabhängig von der Anzahl der Klappenpaare eines Falzklappenzylinders nur einmal in den Falzklappenzylinder eingebaut, so daß die Montage und insbesondere das Justieren nur einmal vorzunehmen sind;
  • auch eine Verwendung des Falzklappenzylinders bei sogenannter Sammelproduktion bringt keine ungleichmäßige Belastung und damit keine ungleichmäßige Abnutzung der Getriebe mit sich, wie dies sonst bei Verwendung eines Getriebes je Falzklappenpaar der Fall wäre;
  • durch Teilung von Zahnrädern in an sich bekannter Weise ist es möglich, die Zahnradpaarungen der Getriebe einfach spielfrei einzustellen und später auch ohne großen Aufwand nachzustellen.
The device for adjusting the folding jaws on a folding jaw cylinder has the following advantages, as has been explained above using three exemplary embodiments:
  • the gears transmitting the adjustment movement have no part designed for self-locking by friction;
  • for the entirety of the folding jaw pairs, the device has a single gear or a combination of a gear block and a reversing direction of rotation acting like a single gear;
  • by using rotating parts, a concentration of the load on individual parts of the device is avoided;
  • The actuating device according to the invention is installed only once in the jaw cylinder regardless of the number of pairs of jaws of a jaw cylinder, so that the assembly and in particular the adjustment are carried out only once;
  • even using the jaw cylinder in a so-called collective production does not result in an uneven load and therefore no uneven wear of the gears, as would otherwise be the case if one gear was used per pair of jaws;
  • by dividing gears in a manner known per se, it is possible to set the gear pairings of the gears simply without play and to readjust them later without great effort.
