Description

Die Erfindung betrifft eine Seiten- und Umfangsregistereinstellvorrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a side and circumferential register setting device according to the preamble of patent claim 1.

Zum Einstellen eines Seiten- und Umfangsregisters sind verschiedene Vorrichtungen bekannt. Die DE-OS 27 20 313 zeigt eine Vorrichtung bei der das Seitenregister durch axiales Verschieben des Übergabezylinders eingestellt wird. Hierzu greift in eine an einem Zylinderzapfenende angeordnete Kulisse eine Rolle ein, die drehbar an einem Schwenkhebel befestigt ist. Der Schwenkhebel ist über ein Handrad mittels eines Schneckengetriebes auslenkbar. Das Umfangsregister wird durch axiales Verschieben eines Zahnkranzes eingestellt. Der Zahnkranz ist auf dem Wellenzapfenende mittels einer Paßfeder axial verschiebbar, jedoch drehfest gelagert. Der Zahnkranz weist außen eine Schrägverzahnung auf, mittels derer er in die Schrägverzahnung eines nachfolgenden Zahnrades eingreift. Eine axiale Verschiebung des Zahnkranzes erfolgt durch Verschwenken einer Rolle die mit einer am Zahnkranz befestigten Kulisse im Eingriff steht. Die Rolle ist drehbar an einem Hebel befestigt, der mittels eines Handrades und eines Schneckengetriebes schwenkbar ist. Die axiale Verschiebung des Zahnkranzes hat, hervorgerufen durch die Schrägverzahnung eine Drehung des Zahnkranzes und mittels einer Paßfeder einer Umfangsdrehung (-verstellung) des Zylinder zur Folge.Various devices are known for setting a page and perimeter register. DE-OS 27 20 313 shows a device in which the side register is set by axially displacing the transfer cylinder. For this purpose, a roller, which is rotatably attached to a pivot lever, engages in a link arranged on a cylinder journal end. The swivel lever can be deflected by means of a worm gear via a handwheel. The circumferential register is set by axially shifting a ring gear. The ring gear is axially displaceable on the shaft journal end by means of a parallel key, but is non-rotatably mounted. The gear rim has helical teeth on the outside, by means of which it engages in the helical teeth of a subsequent gear. An axial displacement of the ring gear takes place by pivoting a roller which is in engagement with a link attached to the ring gear. The roller is rotatably attached to a lever which can be pivoted by means of a handwheel and a worm gear. The axial displacement of the ring gear, caused by the helical toothing, results in a rotation of the ring gear and, by means of a feather key, a circumferential rotation (adjustment) of the cylinder.

Es ist bei der Registereinstellvorrichtung nach der DE-OS 27 20 313 von Nachteil, daß eine Umfangsregisterverstellung nur grob erfolgen kann, da ein funktionsbedingtes Spiel zwischen dem lose auf dem Wellenzapfen des Zylinders gelagerten Zahnkranz und der Welle eine Feineinstellung des Umfangsregisters nicht zuläßt.It is with the register adjuster after DE-OS 27 20 313 disadvantageous that a circumferential register adjustment can only be made roughly, since a function-related play between the ring gear loosely mounted on the shaft journal of the cylinder and the shaft does not permit a fine adjustment of the circumferential register.

Der Erfindung liegt die Aufgabe zugrunde, eine Seiten- und Umfangsregistereinstellvorrichtung für eine Registertrommel einer aus Offset- und Tiefdruckeinheit bestehenden Hybridmaschine zu schaffen, die fein und schnell einregelbar ist, wobei ein zum Antrieb der Registertrommel vorgesehenes Zahnrad nur mit einem weiteren Zahnrad in getrieblicher Verbindung stehen soll.The invention has for its object to provide a side and circumferential register adjustment device for a register drum of a hybrid machine consisting of offset and gravure printing unit, which can be finely and quickly adjusted, a gear provided for driving the register drum being in gear connection only with another gear should.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.The object is achieved by the features of claim 1.

Die Vorteile der Erfindung liegen insbesondere darin, daß die Registereinstellvorrichtung sehr fein ausregelbar ist, so daß sie auch im Wertpapiermaschinenbau, bei dem auf hohe Genauigkeit Wert gelegt wird, zur vollen Zufriedenheit eingesetzt werden kann. In vorteilhafter Ausbildung der Erfindung ist diese mit einer automatischen Steuerung versehen, so daß jeder Bogen während des Maschinenlaufes einzeln ausgemessen und bei Abweichung von einer Soll-Lage automatisch in Seiten- und Umfangslage korrigiert wird.The advantages of the invention are, in particular, that the register setting device can be regulated very finely, so that it can also be used to the full satisfaction in securities machine construction, in which high accuracy is important. In an advantageous embodiment of the invention, this is provided with an automatic control so that each sheet is individually measured during machine operation and is automatically corrected in lateral and circumferential position if there is a deviation from a desired position.

In addition to the register drum 4, all drums and cylinders 2, 3, 6, 7, 8 are mounted directly in side frames 9, 11 of the rotary printing press.

Die Registertrommel 4 besteht u. a. aus einer Koaxialwelle, deren Innenwelle 12 fest mittels ihres linken Endes 13 mit einem linken Hebel 14 und mittels ihres rechten Endes 16 fest mit einem rechten Hebel 17 verbunden ist.The register drum 4 is u. a. from a coaxial shaft, the inner shaft 12 of which is firmly connected by means of its left end 13 to a left lever 14 and by means of its right end 16 to a right lever 17.

Die Hebel 14, 17 sind jeweils auf Bolzen 21, 22 schwenkbar gelagert, die jeweils fest in die Seitengestelle 9, 11 eingepaßt sind, und werden durch Abstandsscheiben 23, 24 von den Seitengestellen 9, 11 getrennt. Die Hebel 14, 17 haben eine gemeinsame Drehachse 26, die in einem Abstand e einer Drehachse 27 einer Außenwelle 28 angeordnet ist.

Mittels eines Bolzens 31; 32 ist der rechte Hebel 17 an eine Schaltstange 34 bzw. der linke Hebel 14 an eine Schaltstange 33 angelenkt. Die Schaltstangen 33, 34 sind zueinander parallel ausgerichtet und jeweils über eine Koppel 36; 37 mit einer in seitengestellfesten Lagerböcken 40, 42 schwenkbar gelagerten Synchronisationswelle 38 verbunden. Die Koppeln 36, 37 sind jeweils fest mit der Synchronisationswelle 38 und gelenkig mit einem ersten Ende 39; 41 der Schaltstangen 33; 34 verbunden.The levers 14, 17 are each pivotably mounted on bolts 21, 22, each of which is firmly fitted into the side frames 9, 11, and are separated from the side frames 9, 11 by spacers 23, 24. The levers 14, 17 have a common axis of rotation 26 which is at a distance e an axis of rotation 27 of an outer shaft 28 is arranged. The outer shaft 28 of the coaxial shaft 12, 28 is rotatably and axially displaceably mounted on the inner shaft 12 by means of needle bearings 29. By means of a bolt 31; 32, the right lever 17 is hinged to a shift rod 34 and the left lever 14 to a shift rod 33. The shift rods 33, 34 are aligned parallel to each other and each via a coupling 36; 37 connected to a synchronization shaft 38 which is pivotably mounted in bearing blocks 40, 42 which are fixed on the side frame. The couplers 36, 37 are each fixed to the synchronization shaft 38 and articulated with a first end 39; 41 of the shift rods 33; 34 connected.

Die Gelenkverbindung zwischen der Koppel 36; 37 und der Schaltstange 33; 34 wird jeweils durch einen Bolzen 43; 44 hergestellt, der mittels einer Zugfeder 46; 47 zur Aufbringung einer Rückstellkraft mit einem gestellfesten Zapfen 48, 49 verbunden ist. An einem zweiten Ende 51 weist die Schaltstange 34 eine drehbar gelagerte Steuerrolle 52 auf, die in Berührungskontakt mit einer axial ausgerichteten Kontur 53 einer verstellbaren Steuerkurve 54 ist. Die Steuerkurve 54 ist mit einem ersten Ende 56 einer Steuerwelle 57 fest verbunden. Die Steuerwelle 57 ist in einem am Seitengestell 11 befestigten Lagerbock 58 drehbar gelagert. Ein zweites Ende 59 ist mit einer Antriebswelle 61 eines Stellmotors 62 formschlüssig gekuppelt. Zur Bestimmung einer Winkelstellung der Abtriebswelle 61 und der Steuerwelle 57 ist ein mit der Abtriebswelle 61 verbundener Impulsgeber 66 verbunden.The articulated connection between the coupling 36; 37 and the shift rod 33; 34 is in each case by a bolt 43; 44 produced by means of a tension spring 46; 47 for applying a restoring force is connected to a frame-fixed pin 48, 49. At a second end 51, the shift rod 34 has a rotatably mounted control roller 52 which is in contact with an axially aligned contour 53 of an adjustable control cam 54. The control cam 54 is fixedly connected to a first end 56 of a control shaft 57. The control shaft 57 is rotatably mounted in a bearing block 58 fastened to the side frame 11. A second end 59 is positively coupled to a drive shaft 61 of a servomotor 62. A pulse generator 66 connected to the output shaft 61 is connected to determine an angular position of the output shaft 61 and the control shaft 57.

Wie aus Fig. 2 ersichtlich ist an ein unteres Ende 67 des Hebels 17 mit einer Steuerkurve 68 mit radial ausgerichteter Kontur 69 fest verbunden, die mit einer Steuerrolle 71 für eine Greiferöffnungsbewegung in Berührungskontakt ist. Die Steuerrolle 71 ist in bekannter Weise drehbar an einem Hebel 72 gelagert, der fest mit einer Greiferwelle 73 verbunden ist. Die Greiferwelle 73 ist schwenkbar in Trägern 74 gelagert, die fest auf der Außenwelle 28 sitzen. Auf einem rechten Ende 76 der Außenwelle 28 sitzt ebenfalls mit dieser Außenwelle 28 fest verbunden ein Zahnrad 77. Das Zahnrad 77 kämmt mit einem Zahnrad 78 der im Walzenzug 1 vorgelagerten Übergabetrommel 2 und wird von diesem angetrieben.As can be seen from FIG. 2, at a lower end 67 of the Lever 17 firmly connected to a control cam 68 with a radially aligned contour 69, which is in contact with a control roller 71 for a gripper opening movement. The control roller 71 is rotatably mounted in a known manner on a lever 72 which is fixedly connected to a gripper shaft 73. The gripper shaft 73 is pivotally mounted in supports 74 which are firmly seated on the outer shaft 28. On a right end 76 of the outer shaft 28, a gear 77 is also fixedly connected to this outer shaft 28. The gear 77 meshes with a gear 78 of the transfer drum 2 upstream in the roller train 1 and is driven by it.

An einer linken Außenseite 79 der Registertrommel 4 ist an einem Träger 74 ein Lagerbock 81 befestigt, der eine drehbar gelagerte Steuerrolle 82 trägt. Die Steuerrolle 82 steht in Berührungskontakt mit einer ringförmigen Stirnfläche 83 einer vertikal angeordneten, in Richtung auf die Außenseite 79 der Registertrommel 4 hin- und von ihr weg schwenkbaren Steuerscheibe 84. Die Steuerscheibe 84 ist an ihrem Oberteil 86 um einen gestellfesten Zapfen 87 schwenkbar gelagert und weist an einem Unterteil 88 eine drehbar gelagerte Steuerrolle 89 auf. Die Steuerrolle 89 steht in Berührungskontakt mit einer axial ausgerichteten Kontur 91 einer Steuerscheibe 92 und rollt auf dieser ab. Die Steuerscheibe 92 ist an einem Ende 53 einer in der Seitenwand 9 drehbar gelagerten Steuerwelle 94 befestigt. Die Steuerwelle 94 wird von einem an der Seitenwand 9 befestigten Stellmotor 96 angetrieben. Zur Aufbringung einer Rückstellkraft für den durch die Steuerscheiben 84, 92 ausgelenkten Schlitten 97, bestehend aus Außenwelle 28, Zahnrad 77 und Trägern 74, sind mehrere Druckfedern 98 vorgesehen, die sich horizontal am Hebel 17 abstützen und auf ein Axiallager 99 wirken, das sich an der Außenwelle 28 ebenfalls axial abstützt.On a left outer side 79 of the register drum 4, a bearing block 81 is fastened to a carrier 74 and carries a rotatably mounted control roller 82. The control roller 82 is in contact with an annular end face 83 of a vertically arranged control disc 84 which can be pivoted towards and away from the outside 79 of the register drum 4. The control disc 84 is pivotably mounted on its upper part 86 about a pin 87 fixed to the frame and has a rotatably mounted control roller 89 on a lower part 88. The control roller 89 is in contact with an axially aligned contour 91 of a control disk 92 and rolls on it. The control disk 92 is fastened to one end 53 of a control shaft 94 which is rotatably mounted in the side wall 9. The control shaft 94 is driven by a servomotor 96 attached to the side wall 9. A plurality of compression springs 98 are used to apply a restoring force for the slide 97 deflected by the control disks 84, 92 and consisting of the outer shaft 28, gear 77 and carriers 74 provided, which are supported horizontally on the lever 17 and act on an axial bearing 99, which is also axially supported on the outer shaft 28.

Die beiden Stellmotoren 62 und 96 sind über elektrische Leitungen (nicht dargestellt) mit einer Rechnereinheit 101 verbunden, von der sie ihre Stellbefehle erhalten. Die Rechnereinheit 101 ist über eine elektrische Leitung 102 mit einer Leseeinrichtung 103 verbunden. Die Leseeinrichtung 103 ist wie in Fig. 1 dargestellt in einem Abstand von der Übergabetrommel 2 angeordnet und dient zur Bestimmung der Lage eines von der Wendetrommel 6 abgenommenen Bogens 5. Ein die Lage des Bogens 5 kennzeichnendes Signal wird an die Rechnereinheit 101 übermittelt und mit entsprechenden Sollwerten für die Seiten- bzw. Umfangslage verglichen. Gleichzeitig empfängt die Rechnereinheit 101 jeweils ein Signal vom Impulsgeber 66, der die Stellung der Steuerkurve 54 und von einem Impulsgeber (nicht dargestellt), der die Stellung der Steuerkurve 92 angibt. Aus diesen Eingangssignalen berechnet die Rechnereinheit 101 Stellgrößen und übermittelt diese zusammen mit einer nicht dargestellten Auswerteschaltung als Stellbefehle an die Stellmotoren 62, 96.The two servomotors 62 and 96 are connected via electrical lines (not shown) to a computer unit 101, from which they receive their positioning commands. The computer unit 101 is connected to a reading device 103 via an electrical line 102. As shown in FIG. 1, the reading device 103 is arranged at a distance from the transfer drum 2 and is used to determine the position of a sheet 5 removed from the turning drum 6. A signal characterizing the position of the sheet 5 is transmitted to the computer unit 101 and with corresponding Setpoints for the lateral or circumferential position compared. At the same time, the computer unit 101 receives a signal from the pulse generator 66 which indicates the position of the control curve 54 and from a pulse generator (not shown) which indicates the position of the control curve 92. The computer unit 101 calculates manipulated variables from these input signals and transmits them together with an evaluation circuit, not shown, as actuating commands to the actuators 62, 96.

Die Einstellung des Umfangsregisters geschieht wie folgt. Der Stellmotor 62 dreht je nach Umfangslage des Bogens 5 auf der Übergabetrommel 2 rechts- oder linksherum, wodurch auch die Steuerkurve 54 entsprechend mitgeschwenkt wird. Durch die Kontur 53 der Steuerkurve 54 wird die Schaltstange 34 mittels der Steuerrolle 52 gegen die Kraft der Zugfedern 46, 47 verschoben. Hierdurch wird der an die Schaltstange 34 angelenkte Hebel 17 um die Drehachse 26 des Bolzens 22 geschwenkt. Über die Koppeln 36, 37 und die Synchronisationswelle wird der Hebel 14 entsprechend um den Bolzen 21 mitverschwenkt. Hierbei bewegt sich die Drehachse 27 der Innenwelle 16 auf einer Kreisbahn um die Drehachse 26 der Bolzen 21, 22. Da der Schwenkwinkel klein ist, kann die Kreisbewegung als geradlinige Verlagerung der Innenwelle 16 angesehen werden. Durch den Eingriff der Zahnräder 77, 78 erfährt das Zahnrad 77 und damit der Schlitten 97 eine Schwenkung um die Zahneingriffsstelle A der Zanräder 77, 78, die auch gleichzeitig den Übergabepunkt A zwischen Übergabetrommel 2 und Registertrommel 4 kennzeichnet. Der Übergabepunkt A ist konstant und ändert seine Lage nicht. Da die Übergabetrommel 3 nicht im Zahneingriff mit der Registertrommel 4 steht, wird diese nicht mitgedreht und es kommt zu einer Relativbewegung eines Übergabepunktes B zwischen den Greifern 104 der Registertrommel 4 und den Greifern 106 der Übergabetrommel 3. Der Übergabepunkt B ist in seiner Lage veränderbar. Die Greifer 104, 106 sind so ausgebildet, daß sie den Bogen 5 über einen ausreichend großen Bereich (ca. 3 mm) registerhaltig greifen und festhalten können. Eine Verschiebung der Schaltstange 34 z. B. in Pfeilrichtung nach links hat eine Schwenkung der Registertrommel 4 im Uhrzeigersinn und damit eine Verlagerung der Übergabestelle B nach links, bzw. in Bogentransportrichtung gesehen nach vorn zur Folge.The circumferential register is set as follows. Depending on the circumferential position of the sheet 5, the servomotor 62 rotates on the transfer drum 2 to the right or to the left, as a result of which the control cam 54 is also pivoted accordingly. Due to the contour 53 of the control cam 54, the shift rod 34 is against the force by means of the control roller 52 the tension springs 46, 47 shifted. As a result, the lever 17 articulated on the shift rod 34 is pivoted about the axis of rotation 26 of the pin 22. The lever 14 is correspondingly pivoted about the pin 21 via the coupling 36, 37 and the synchronization shaft. Here, the axis of rotation 27 of the inner shaft 16 moves on a circular path around the axis of rotation 26 of the bolts 21, 22. Since the swivel angle is small, the circular movement can be regarded as a linear displacement of the inner shaft 16. Through the engagement of the gear wheels 77, 78, the gear wheel 77 and thus the slide 97 are pivoted about the tooth engagement point A of the gear wheels 77, 78, which at the same time characterizes the transfer point A between transfer drum 2 and register drum 4. The transfer point A is constant and does not change its position. Since the transfer drum 3 is not in meshing engagement with the register drum 4, this is not rotated and there is a relative movement of a transfer point B between the grippers 104 of the register drum 4 and the grippers 106 of the transfer drum 3. The position of the transfer point B can be changed. The grippers 104, 106 are designed such that they can grip and hold the sheet 5 in register over a sufficiently large area (approx. 3 mm). A shift of the shift rod 34 z. B. in the direction of the arrow to the left has a pivoting of the register drum 4 clockwise and thus a shift of the transfer point B to the left, or as seen in the sheet transport direction to the front.

Zur Einstellung des Seitenregisters dreht der Stellmotor 96, je nach Lage des Bogens 5 auf der Übergabetrommel 2, rechts- oder linksherum, wodurch die Steuerkurve 92 entsprechend mitgeschwenkt wird. Durch die Kontur 91 der Steuerkurve 92 wird mittels der Steuerrolle 89 die Steuerscheibe 84 um den Bolzen 84 verschwenkt, so daß die Steuerrolle 82 beim Abrollen auf der Stirnfläche 83 der Steuerscheibe 84 den Schlitten 97 mit oder gegen die Rückstellkraft der Druckfedern 98 axial verschiebt.To set the side register, the servomotor 96 rotates, depending on the position of the sheet 5 on the transfer drum 2, clockwise or counterclockwise, whereby the control cam 92 is pivoted accordingly. Due to the contour 91 of the control cam 92, the control disk 84 is pivoted about the bolt 84 by means of the control roller 89, so that the control roller 82 axially moves the slide 97 with or against the restoring force of the compression springs 98 when rolling on the end face 83 of the control disk 84.

Es besteht selbstverständlich auch die Möglichkeit, nach Entfernen der Synchronisationswelle 38 die Hebel 14, 17 getrennt zu verschwenken, in dem für den Hebel 14 entsprechende Stelleinrichtungen 66, 57, 54, 52 wie für den Hebel 17 vorgesehen werden. In diesem Fall ist auch eine asynchrone Steuerung der Hebel 14, 17 denkbar, wodurch eine Schrägstellung der Registertrommel 4 erreicht würde, um z. B. Verschränkungsfehler des Bogens 5 korrigieren zu können.Of course, there is also the possibility, after removing the synchronization shaft 38, of pivoting the levers 14, 17 separately, in the corresponding actuating devices 66, 57, 54, 52 for the lever 14, as for the lever 17. In this case, an asynchronous control of the levers 14, 17 is also conceivable, whereby an inclined position of the register drum 4 would be achieved in order, for. B. Correcting entanglement errors of the sheet 5.
