Abstract

The sheet handler in a printer is controlled by a cam follower comprising a roller (3) at the end of a pivot arm (2) displaced by a cam profile (4) on the print roller. For a positive tracking, without bounce, the pivot arm is linked to a control arm (7), via a pivot (6) and with the end of the control arm linked to the free end of a second pivot arm (13) which is spring loaded (12). The pivot (1) of the first lever can be the suction lifter for the sheets, or can control the axis of the lifting cylinder for the sheets.

Description

Die Erfindung betrifft eine Steuereinrichtung für ein Bogentransportsystem in einer Bogenrotationsdruckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to a control device for a sheet transport system in one Sheet-fed rotary printing machine according to the preamble of the main claim.

Eine Einrichtung dieser Art ist beispielsweise aus der DE-PS 934 770 bekannt. Das Bogentransportsystem ist hier als Greiferanordnung für einen Druckzylinder ausgebildet und reguliert den Greiferdruck an der Bogenvorderkante unter Berücksichtigung der Zugbelastung. Die Greiferanordnung besteht im wesentlichen aus einer Greiferwelle mit einem Rollenhebel, welcher auf einer Steuerkurve umläuft. Die Greiferwelle ist in Greiferschließrichtung mittels einer auf einer Stange angeordneten Druckfeder zusätzlich kraftschlüssig belastet. Mittels Kurvensteuerung wird gegen die Federkraft die Greiferwelle geöffnet. In einer Weiterbildung kann die Federkraft unverändert bleiben oder verringert werden, in dem die Druckfeder tragende Stange verlängert ist und mit einem am Zylinder angelenkten Hebel sowie Rollen mit einer zusätzlichen Kurvensteuerung getriebetechnisch gepaart ist.
Nachteilig ist hierbei, daß die auf das Kurvengetriebe in erster Ausbildung wirkenden Kräfte den Verschleiß fördern und das Abheben des Rollenhebels von der Steuerkurve im ungünstigsten Fall fördern. Die zweite Ausbildung ist aufwendig, da eine zusätzliche Steuerkurve mit Hebel und Rolle erforderlich ist. Weiterhin wird in Folge des Durchganges der Stange durch die Zylinderachse viel Bauraum benötigt, was den Einsatz dieser Lösung für mehrfach große Druckzylinder (bezogen auf einen einfachgroßen Formzylinder) erschwert. A device of this type is known for example from DE-PS 934 770. The sheet transport system is designed here as a gripper arrangement for a printing cylinder and regulates the gripper pressure on the front edge of the sheet taking into account the tensile load. The gripper arrangement essentially consists of a gripper shaft with a roller lever, which rotates on a control cam. The gripper shaft is additionally non-positively loaded in the gripper closing direction by means of a compression spring arranged on a rod. The gripper shaft is opened by means of cam control against the spring force. In a further development, the spring force can remain unchanged or reduced by extending the rod carrying the compression spring and pairing it with the transmission technology with a lever articulated on the cylinder and rollers with an additional curve control.
The disadvantage here is that the forces acting on the cam mechanism in the first embodiment promote wear and promote the lifting of the roller lever from the control cam in the worst case. The second training is complex because an additional control curve with lever and roller is required. Furthermore, as a result of the rod passing through the cylinder axis, a large amount of installation space is required, which makes it difficult to use this solution for multi-size impression cylinders (based on a single-size forme cylinder).

Eine weitere Steuereinrichtung ist aus der EP 0 452 721 B1 bekannt. Das Bogentransportsystem ist hier als Saugersystem in einer Bogenübergabetrommel zum Wenden des Bogens ausgebildet, welches mit zwei nachgeordneten, aufeinander zu schwingenden Greifersystemen zum Wenden des Bogens nach dem Prinzip der Hinterkantenwendung in Funktionsverbindung ist.Another control device is known from EP 0 452 721 B1. The sheet transport system is here as a suction system in a sheet transfer drum Turning the arch formed, which with two subordinate, one on top of the other to swinging gripper systems for turning the bow according to the principle the trailing edge application is in functional connection.

Gemäß der DE 43 39 388 A1 ist eine Steuereinrichtung für Greifer in Wendetrommeln bekannt. An einer Greiferwelle ist ein Greiferwellenhebel angeordnet, der am Ende eine Kurvenrolle trägt. Die von einer Zugfeder kraftschlüssig belastete Kurvenrolle ist mit einer Kurvenbahn gepaart. Dabei ist die Kurvenbahn innerhalb eines Rollenhebels endseitig integriert und die Kurvenrolle ragt in den Rollenhebel zwecks Bildung des Kurvengelenkes mit der Kurvenbahn hinein. Der Rollenhebel weist einen Drehpunkt auf und trägt am von der Kurvenbahn abgewandten Ende weiterhin eine Rolle, welche mit einer Steuerkurve gepaart ein weiteres Kurvengelenk bildet. Der Rollenhebel ist zusätzlich mit einer Druckfeder in Funktionsverbindung, welche die Rolle kraftschlüssig auf der Steuerkurve führt.According to DE 43 39 388 A1 there is a control device for grippers in turning drums known. A gripper shaft lever is arranged on a gripper shaft, who ultimately wears a cam roller. The frictionally loaded by a tension spring Cam roller is paired with a cam track. Here is the cam track integrated at the end within a roller lever and the cam roller protrudes into the Roller lever to form the cam joint with the cam track. Of the Roller lever has a fulcrum and carries on the side facing away from the cam track End of a role, which is paired with a control curve forms another curve joint. The roller lever is also with a compression spring in functional connection, which leads the role non-positively on the control cam.

Da während des Bewegungsablaufes deratiger Einrichtungen eine vorzugsweise kraftschlüssige Zwanglaufsicherung bei Kurvengelenken erforderlich ist, ist es nachteilig, daß die Kraftpaarung zwischen Steuerkurve (Kurvenglied) und Rollenhebel (Eingriffsglied) ständig wechselnden Belastungen unterliegen.
Bei Bogentransportsystemen, wie rotierenden Bogenführungszylindern sowie schingenden Vorgreifern ist insbesondere bei höheren Maschinengeschwindigkeiten (etwa > 10.000 Bogen/Stunde) bekannt, daß durch zusätzliche Trägheitskräfte, beispielsweise Fliehkräfte, die Kraftpaarung im Kurvengelenk partiell aufgehoben wird. Andererseits fördern ständige sprunghafte Lastwechselreaktionen den Verschleiß der als Kurvengetriebe ausgebildeten Steuereinrichtung. Dies wirkt sich negativ auf die Druckqualität aus. Since during the course of movement of such devices a preferably non-positive restraint is required for corner joints, it is disadvantageous that the force pairing between the control cam (cam member) and roller lever (engaging member) is subject to constantly changing loads.
In sheet transport systems, such as rotating sheet guide cylinders and looping pre-grippers, it is known, in particular at higher machine speeds (about> 10,000 sheets / hour), that the pairing of forces in the curved joint is partially eliminated by additional inertial forces, for example centrifugal forces. On the other hand, constant, sudden load change reactions promote the wear of the control device designed as a cam mechanism. This has a negative impact on print quality.

Der Erfindung liegt die Aufgabe zugrunde, eine Steuereinrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere einen sicheren Zwanglauf im Kurvengelenk gestattet und die Lastwechselreaktionen innerhalb der Einrichtung spürbar reduziert.The invention has for its object a control device of the beginning to create described type, which avoids the disadvantages mentioned, in particular allows a safe forced run in the curve joint and the load change reactions noticeably reduced within the facility.

Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, the task is characterized by the training features of the Main claim solved. Further training results from the subclaims.

Die erfindungsgemäße Steuereinrichtung betrifft ein Bogentransportsystem, welches in rotierenden Bogenführungszylindern, wie Druckzylindern, Transfertrommeln und Wendeeinrichtungen, Anlagetrommeln sowie schwingenden Vorgreifern einsetzbar ist. Dabei ist das Bogentransportsystem vorteilhaft durch eine Vielzahl von auf einer Greiferwelle angeordneten Greifern oder einem pneumatisch beaufschlagbaren Bogenhaltesystem, z.B. eine Saugerwelle mit entsprechenden Saugersystemen, gebildet. In einer Weiterbildung ist das Bogentransportsystem auch als Schwingsystem für Schöndruck- und/oder Widerdruckgreifer und/oder Sauger einsetzbar.
Die Steuereinrichtung für das Bogentransportsystem ist für Bogenrotationsdruckmaschinen geeignet, die ausschließlich im Schöndruck als auch umschaltbar im Schöndruck - bzw. Schön- und Widerdruck betreibbar sind.
In bekannter Weise ist die Steuerwelle (Greiferwelle bzw. Saugerwelle) des Bogentransportsystemes mit einem Rollenhebel mit Rolle, der mit einer Kurve gepaart ist, gekoppelt. Die Steuerwelle stellt getriebetechnisch ein Drehgelenk mit einem Drehpunkt dar. Dabei ist der Drehpunkt - wie oben aufgeführt - nicht auf eine Steuerwelle beschränkt. Vielmehr ist statt der Steuerwelle auch eine weitere, um den Drehpunkt des Drehgelenkes schwingende Platte als Steuerkurve, vorzugsweise eines Bogenführungszylinders anordbar, welche gleichzeitig die Funktion des Rollenhebels übernimmt. The control device according to the invention relates to a sheet transport system which can be used in rotating sheet guide cylinders, such as impression cylinders, transfer drums and turning devices, contact drums and vibrating pre-grippers. The sheet transport system is advantageously formed by a plurality of grippers arranged on a gripper shaft or a pneumatically actuated sheet holding system, for example a suction shaft with corresponding suction systems. In a further development, the sheet transport system can also be used as a vibrating system for straight-pressure and / or counter-pressure grippers and / or suction devices.
The control device for the sheet transport system is suitable for sheet-fed rotary printing presses which can be operated exclusively in straight printing as well as switchable in straight printing or face and reverse printing.
In a known manner, the control shaft (gripper shaft or suction shaft) of the sheet transport system is coupled to a roller lever with roller, which is paired with a curve. In terms of transmission technology, the control shaft represents a swivel joint with a pivot point. The pivot point - as mentioned above - is not limited to a control shaft. Instead of the control shaft, it is also possible to arrange a further plate, which swings around the pivot point of the swivel joint, as a control cam, preferably an arc guide cylinder, which at the same time takes over the function of the roller lever.

Der Rollenhebel entspricht getriebetechnisch einer Kurvenschwinge und ist mit einem Energiespeicher unter Zwischenschaltung einer gestellfesten Schwinge und einer Koppel getriebetechnisch verbunden, derart, daß der Zwanglauf im durch Rolle und Kurve gebildeten Kurvengelenk gesichert ist. Unter Zwanglaufsicherung ist dabei die ständige Berührung von Rolle (Eingriffsglied) und Kurve (Kurvenglied) im Kurvengelenk zu verstehen, da während des Bewegungsablaufes Kurven- und Eingriffsglied ständig in Berührung sein müssen.
Die Zwanglaufsicherung ist dabei durch Kraftpaarung erzielbar, welche durch einen Energiespeicher, vorteilhaft in Form eines Federsystems, alternativ durch ein Hydraulik- oder Pneumatikelement, erzeugt ist.
Darüberhinaus ist die Kurvenschwinge der Steuereinrichtung mit weiteren Mitteln gekoppelt, so daß die Kraftpaarung im Kurvengelenk zur Erzielung eines gleichmäßigeren Zwanglaufes von Kurvenglied und Eingriffsglied keinen sprunghaften Lastwechselreaktionen ausgesetzt ist. Das Kraftfeld in der Steuereinrichtung ist dahingehend verbessert, daß die Kräfte, die außerhalb der Drehgelenke, dem Kurvengesetz folgend, auf die Getriebeglieder wirken auf einem definierten Niveau liegen.The roller lever corresponds in terms of transmission technology to a swing arm and is connected to an energy storage device with the interposition of a frame-fixed swing arm and a coupling, in such a way that the positive movement is ensured in the curve joint formed by the roller and curve. Forced running protection means the constant contact of the roller (engaging element) and the curve (curve element) in the curve joint, since the curve and engaging element must be in constant contact during the course of the movement.
The forced run protection can be achieved by a pair of forces, which is generated by an energy store, advantageously in the form of a spring system, alternatively by a hydraulic or pneumatic element.
In addition, the cam rocker of the control device is coupled to other means, so that the force pairing in the cam joint is not exposed to sudden load change reactions in order to achieve a more uniform forced running of the cam member and the engaging member. The force field in the control device is improved in such a way that the forces which act on the transmission members outside the swivel joints, following the curve law, are at a defined level.

Dem letzten Druckwerk 16 ist ein Ausleger 20 mit einem mehrere Greifersysteme tragenden, umlaufenden Kettensytem 19 in an sich bekannter Weise nachgeordnet.

Die erfindungsgemäße Steuereinrichtung ist in Fig. 1 allgemein für einen Bogenführungszylinder dargestellt. Das kinematische Schema zeigt ein Drehgelenk 1, welches getriebetechnisch gestellfest am Bogenführungszylinder angeordnet ist. Gestellfest ist hiermit der rotierende Bogenführungszylinder, beispielsweise in Form eines Druckzylinders 25, einer Wendetrommel 23, einer Transfertrommel 24, einer Anlagetrommel bzw. auch ein schwingendes Vorgreifersystem (Letztere nicht gezeigt) zu verstehen.The control device according to the invention is generally shown in FIG. 1 for a sheet guiding cylinder shown. The kinematic diagram shows a swivel joint 1, which is technically fixed to the sheet guide cylinder on the frame. The rotating sheet guide cylinder, for example in Form of a printing cylinder 25, a turning drum 23, a transfer drum 24, a system drum or a vibrating pre-gripper system (the latter not shown) to understand.

An dem Drehgelenk 1 ist eine Kurvenschwinge 2 endseitig angelenkt, welche am freien Ende eine mit einer feststehenden Kurve 4 in Funktionsverbindung stehende Rolle 3 trägt. An der Kurvenschwinge 2 ist ein Drehgelenk 6 angeordnet, welches mit einer Koppel 7 verbunden ist.
Alternativ ist das Drehgelenk 6 (mit angelenkter Koppel 7) auch in der Drehachse der Rolle 3 anordbar.
Die Koppel 7 ist weiterhin mit einem an einer separaten Schwinge 13 angeordneten Drehgelenk 8 verbunden. Die Koppel 7 ist somit getriebetechnisch ein binäres Glied mit zwei Drehgelenken 6, 8. Die Schwinge 13 ist einem gestellfesten Drehgelenk 10 am Bogenführungszylinder angeordnet und weist zwischen den Drehgelenken 8, 10 ein weiteres Drehgelenk 9 auf.
Alternativ ist das Drehgelenk 9 auch in der Drehachse des Drehgelenkes 8 anordbar.
Das Drehgelenk 9 ist mit einem Energiespeicher 12 gekoppelt, wobei der Energiespeicher 12 in einem gestellfesten Drehgelenk 11 am Bogenführungszylinder angeordnet ist. Alle Drehgelenke 1, 6, 8, 9, 10, 11 weisen jeweils einen Gelenkfreiheitsgrad von f = 1 auf.
Die Schwinge 13 ist alternativ auch als Winkelhebel ausführbar und ist somit ein ternäres Glied mit den drei Drehgelenken 8, 9, 10.At the swivel joint 1, a curved rocker arm 2 is articulated at the end, which carries at the free end a roller 3 which is functionally connected to a fixed curve 4. A swivel joint 6, which is connected to a coupling 7, is arranged on the cam rocker arm 2.
Alternatively, the swivel joint 6 (with articulated coupling 7) can also be arranged in the axis of rotation of the roller 3.
The coupling 7 is also connected to a swivel joint 8 arranged on a separate rocker 13. The coupling 7 is thus a binary link with two rotary joints 6, 8 in terms of transmission technology. The rocker 13 is arranged on the bow guide cylinder with a fixed rotary joint 10 and has a further rotary joint 9 between the rotary joints 8, 10.
Alternatively, the swivel joint 9 can also be arranged in the axis of rotation of the swivel joint 8.

In a second embodiment, the control device according to FIG. 2 is arranged on a turning drum 23 with center point 5 and relates to a sheet-fed printing machine which can be operated in straight printing as well as in perfecting. Here corresponds to:
  • the swivel joint 1 of a fixed axis of rotation on the turning drum 23,
  • the swing arm 2 (with roller 3) of a plate pivotally mounted on the above-mentioned axis of rotation of the swivel joint 1, which has a double function:
  • 1. as roller lever and
  • 2. has as a control curve for vibration systems, in particular for straight-pressure and counter-pressure grippers, the control curve being formed by two curve branches 14, 15 and the roller 3 is in turn paired with curve 4, which pivots the plate about the axis of rotation (swivel joint 1) controls and the curve branches 14, 15 with further roller levers (with roller) form curved joints for straight-pressure or counter-pressure gripper systems,

  • the swivel joint 9 is the articulation point of the energy store 12, which is designed here as a spring system,

Das Bewegungsgesetz der Kurve 4 sieht bekanntlich höchste und tiefste Stellen am Kurvenglied vor, um die gewünschten zeitlich ablaufenden, periodischen Bewegungen realisieren zu können. Getriebetechnisch bilden Rolle 3 sowie Kurve 4 an deren Paarungsstelle ein Kurvengelenk, wobei die Rolle 3 kraftschlüssig durch den Energiespeicher 12, z.B. ein Federsystem mit Druckfeder oder Zugfeder, in ihrem Zwanglauf gesichert ist.
Eine definierte Kraft für die Zwanglaufsicherung von Rolle 3 und Kurve 4 im Kurvengelenk wird mit der erfindungsgemäßen Steuereinrichtung im wesentlichen über das gesamte Bewegungsgesetz hinweg beibehalten.
Realisiert wird es dadurch, daß die an der Wendetrommel 23 gestellfest im Drehgelenk 10 gelagerte Schwinge 13 zwei Drehgelenke 8, 9 aufweist. Die Schwinge 13 kompensiert die aus dem Bewegungsgesetz der Kurve 4 resultierenden und üblicherweise Lastwechselreaktionen bewirkenden Kräfte indem durch die Schwingbewegung der Schwinge 13 um das Drehgelenk 10 sich die Hebelverhältnisse als auch die Kraftverhältnisse und somit die Momente ändern.As is known, the law of motion of curve 4 provides for the highest and lowest points on the curve element in order to be able to implement the desired periodic movements which run in time. In terms of transmission technology, roller 3 and curve 4 form a curved joint at their mating point, roller 3 being non-positively secured in its forced operation by energy store 12, for example a spring system with compression spring or tension spring.
A defined force for the forced running protection of roller 3 and curve 4 in the curve joint is maintained with the control device according to the invention essentially over the entire law of motion.
It is realized in that the rocker arm 13 mounted on the turning drum 23 in the swivel joint 10 has two swivel joints 8, 9. The rocker arm 13 compensates the forces resulting from the law of motion of the curve 4 and usually effecting load change reactions by the lever arm ratios as well as the force ratios and thus the moments changing due to the rocking motion of the rocker arm 13.

Gemäß Fig. 4 ist die Schwinge 13 um die Drehachse des Drehgelenkes 10 verschwenkt dargestellt, wenn das Kurvengelenk (Rolle 3, Kurve 4) annähernd den tiefsten Punkt am Kurvenkörper der Kurve 4 einnimmt. Dies entspricht der in Fig. 2 mit vollen Linien gezeigten Position. In Kraftrichtung des Energiespeichers 12 wirkt eine Kraft F1, welche mit einem Hebelarm l1 (Lot vom Drehpunkt Drehgelenk 10 auf die Kraftrichtung F1) das Moment M1 ergibt. Weiterhin wirkt an der Koppel 7 eine Kraft F2, welche mit einem Hebelarm l2 (Lot vom Drehpunkt Drehgelenk 10 auf Kraftrichtung F2) das Moment M2 ergibt.
Die Schwinge 13 mit Drehgelenken 8, 9 ist mit den Hebelarmen l1, l2 derart ausgebildet, daß am tiefsten Punkt des Kurvenkörpers (Kurve 4) für die Hebelverhältnisse gilt: l1 > l2.4, the rocker 13 is shown pivoted about the axis of rotation of the swivel joint 10 when the curve joint (roller 3, curve 4) approximately approaches the lowest point on the curve body of curve 4. This corresponds to the position shown in full lines in FIG. 2. A force F 1 acts in the direction of force of the energy store 12, which gives the moment M 1 with a lever arm l 1 (perpendicular from the pivot point of the pivot joint 10 to the direction of force F 1 ). Furthermore, a force F 2 acts on the coupling 7, which results in the moment M 2 with a lever arm l 2 (perpendicular from the pivot point of the pivot joint 10 in the direction of force F 2 ).
The rocker 13 with swivel joints 8, 9 is designed with the lever arms l 1 , l 2 in such a way that the following applies to the lever ratios at the lowest point of the curve body (curve 4): l 1 > l 2 .

Gemäß Fig. 5 ist die Schwinge 13 um die Drehachse des Drehgelenkes 10 verschwenkt in der Position dargestellt, wenn das Kurvengelenk (Rolle 3, Kurve 4) annähernd den höchsten Punkt am Kurvenkörper (Kurve 4) einnimmt. Dies entspricht der in Fig. 2 mit gestrichelten Linien gezeigten Position. In Kraftrichtung des Energiespeichers 12 wirkt eine Kraft F1', welche mit einem Hebelarm l1' das Moment M1' ergibt. An der Koppel 7 wirkt eine Kraft F2' , welche mit einem Hebelarm l2' das Moment M2' ergibt. Am höchsten Punkt des Kurvenkörpers (Kurve 4) gilt für die Hebelverhältnisse: l1' < l2'.5, the rocker 13 is shown pivoted about the axis of rotation of the swivel joint 10 in the position when the cam joint (roller 3, curve 4) almost approaches the highest point on the cam body (curve 4). This corresponds to the position shown in broken lines in FIG. 2. A force F 1 'acts in the direction of force of the energy store 12, which force gives the moment M 1 ' with a lever arm l 1 '. A force F 2 'acts on the coupling 7, which gives the moment M 2 ' with a lever arm l 2 '. At the highest point of the curve body (curve 4) the following applies to the leverage ratios: l 1 '<l 2 '.

Durch die Schwenkbewegung der Schwinge 13 um die Drehachse (Drehgelenk 10) und damit Veränderung der Kräfte F1, F2, F1', F2' sowie der Hebelarme l1, 12, 11', l2' werden die Momente M1, M2, M1',M2' derart zueinander kompensiert, daß sich stets eine Kraft definierter Größe im Kurvengelenk von Rolle 3 und Kurve 4 ergibt, wobei die Schwenkbewegung und damit Änderung der Hebelverhältnisse der Schwinge 13 in Verbindung mit dem Kurvengesetz der Kurve 4 erfolgt. Entsprechend der Ausbildung der Hebelarme an der Schwinge 13 ist die Anstellkraft der Rolle 3 im Kurvengelenk an den höchsten und tiefsten Punkten des Kurvenkörpers annähernd gleich oder bevorzugt ist die Anstellkraft der Rolle 3 im tiefsten Kurvenpunkt größer als im höchsten Kurvenpunkt, wobei dann an der Schwinge 13 die Hebelverhältnisse l1 > l2 im tiefsten Kurvenpunkt und l1' < l2' im höchsten Kurvenpunkt gelten.
Die Steuereinrichtung ist nicht auf einen Bogenführungszylinder mit einfach großem Durchmesser, bezogen auf einen einfachgroßen Formzylinder, beschränkt. Vielmehr eignet sich die Einrichtung auch für mehrfachgroße Bogenführungszylinder. Beispielsweise ist bei einem doppeltgroßem Bogenführungszylinder die Steuereinrichtung um 180° symmetrisch versetzt und zueinander spiegelbildlich am Zylinderumfang anordbar.The moments become due to the pivoting movement of the rocker 13 about the axis of rotation (swivel joint 10) and thus change of the forces F 1 , F 2 , F 1 ', F 2 ' and the lever arms l 1 , 1 2 , 1 1 ', l 2 ' M 1 , M 2 , M 1 ', M 2 ' compensated for each other in such a way that there is always a force of a defined size in the curve joint of roller 3 and curve 4, the pivoting movement and thus changing the lever ratios of the rocker 13 in connection with the curve law curve 4 takes place. According to the design of the lever arms on the rocker 13, the contact force of the roller 3 in the curve joint at the highest and lowest points of the cam body is approximately the same or, preferably, the contact force of the roller 3 is greater in the lowest curve point than in the highest curve point, with the rocker 13 then the leverage ratios l 1 > l 2 at the lowest curve point and l 1 '<l 2 ' at the highest curve point apply.
The control device is not limited to a sheet guiding cylinder with a simply large diameter, based on a single-sized forme cylinder. Rather, the device is also suitable for multi-size sheet guiding cylinders. For example, in the case of a double-sized sheet guiding cylinder, the control device is offset symmetrically by 180 ° and can be arranged mirror-inverted to one another on the cylinder circumference.

Die Wirkungsweise ist wie folgt: In der ersten Ausbildung für einen Bogenführungszylinder, insbesondere einen Druckzylinder 25, ist die Kurve 4 an einem Gestell fixiert und die Rolle 3 läuft auf der Kurve 4 um. Erreicht die Rolle 3 den tiefsten Kurvenpunkt wird die Kurvenschwinge 2, hier als Rollenhebel, mit der dem Drehgelenk 1 entsprechenden Greiferwelle (ggf. Saugerwelle) verschwenkt, so daß die Greifer geöffnet werden. Erreicht die Rolle 3 den höchsten Kurvenpunkt, so wird mittels Schwenkbewegung der Kurvenschwinge 2 die Greiferwelle (ggf. Saugerwelle) betätigt, so daß die Greifer wieder geschlossen sind.The mode of operation is as follows: In the first training for a sheet guiding cylinder, in particular a pressure cylinder 25, the curve 4 is on one Frame fixed and roller 3 revolves on curve 4. Reach role 3 the the lowest curve point is the swing arm 2, here as a roller lever, with the the gripper shaft corresponding to the swivel joint 1 (possibly suction shaft) is pivoted, so that the grippers are opened. If roller 3 reaches the highest curve point, so the gripper shaft by means of pivoting movement of the swing arm 2 (possibly suction shaft) actuated so that the grippers are closed again.

In der zweiten Ausbildung für die Wendetrommel 23 ist die Kurve 4 wiederum am Gestell fixiert und die Rolle 3 läuft auf der Kurve 4 um. Erreicht die Rolle 3 den tiefsten Kurvenpunkt wird die Kurvenschwinge 2, hier Rollenhebel und Steuerkurve für Schwingsysteme, um das Drehgelenk 1 pendelnd geschwenkt, derart, daß über den Kurvenast 14 ein Widerdruckgreifersystem einschwingbar ist. Erreicht die Rolle 3 den höchsten Kurvenpunkt wird die Kurvenschwinge 2 um das Drehgelenk 1 pendelnd geschwenkt, derart, daß über den Kurvenast 15 ein Schöndruckgreifersystem einschwingbar ist. In the second embodiment for the turning drum 23, the curve 4 is again on Frame fixed and roller 3 revolves on curve 4. Reach role 3 the the lowest curve point is the curve rocker 2, here roller lever and control curve for swing systems, pivoted about the swivel joint 1, such that A counter pressure gripper system can be swung in via the curve branch 14. Reached the roller 3 has the highest curve point, the swing arm 2 around the swivel 1 pivoted, such that a fine pressure gripper system over the curve branch 15 is swingable.
