Definitions
- the invention relates to a printing unit of a rotary printing press according to the preamble of claim 1.
- a device which moves the bearing block of the forme cylinder, which is mounted on a longitudinal guide, by means of a controlled axis to adjust the side register.
- These controlled axes are known to be very expensive and expensive.
- the present invention has set itself the task of creating a printing unit, which allows a simple yet accurate adjustment of the side register and also allows a fast larger axial movement of the forme cylinder for decoupling purposes.
- the bearing block is due to the contact pressure of the fluid-operated cylinder working at the adjustable stop. Due to the adjustable stop the form cylinder is moved over its bearing blocks and thus regulated with the adjustable stop and with the aid of a controller and a scanning optics in the form of a camera, the page register. The fluid-operated cylinder moves on the drive-side mounting the forme cylinder in the coupling movement.
- the previously set positions of the axial register or page register in contrast to a device for adjusting the side register with a controlled axis, remain in a decoupling of the forme cylinder. After completion of the coupling movement, a controlled axis would have to approach the previously set positions again with the required accuracy. This costs time or increases the time required for coupling and exact positioning of the forme cylinder at preset positions.
- the present inventive device has a positioning drive, which can perform at different speeds required for the correction of the page register positioning and thus is able to use larger positioning speeds in large necessary procedures. Since with large register deviations the printed copies must be classified as bad, a large positioning speed for the printed image is not disadvantageous. It is significant, however, that by means of a large positioning speed, the time for the correction of the register deviation, in particular the compensation of the deviation of the page register, is considerably shortened. Furthermore, the harmless for the print image positioning speed depends on the speed of the plate cylinder. The faster it turns, the faster it can be positioned.
- the Fig. 1 shows a printing press, consisting of a paper roll changer 1, double printing 2 to 5, a dryer 6, a cooling unit 7 and a further processing 8, for example, a folder.
- Each of the double printing units 2 to 5 has two forme cylinders 9 and 10 and two transfer cylinders 11 and 12, respectively.
- the transfer cylinders 11; 12 transmit that on the form cylinders 9; 10 existing colored print image on a paper web 13, which is thus printed on both sides four-color when going through in the direction 14.
- the register control on the circumference of the forme cylinder 9; 10 takes place via the drive, in particular via individual drive motors, the register control of the forme cylinder 9; 10 in the axial direction, ie the regulation of the page register, will be described in more detail below.
- the structure of the form cylinder storage is based on the Fig. 2 and Fig. 3 shown.
- the forme cylinder 10 is rotatably mounted in bearing blocks 17 and 18 and is driven by a drive 19, for example an electric motor.
- the support of the cylinder on the bearing block 18 between the cylinder axis 20 and spindle axis 21 is releasable on a cone 22 via a screw 23.
- the bearing block 17 is mounted on guides 24 and the bearing block 18 on guides 25.
- the bearing block 17 in the direction of 26 and 27 and the bearing block 18 in the direction 28 and 29, respectively.
- the bearing block 17 is designed as a fixed bearing, the bearing block 18 as a movable bearing, which allows a certain displacement in the directions 26 and 27.
- FIGS. 5 and 6 show now in enlarged detail the Figures 3 and 4 as the register adjustment, ie the means for adjusting the side register of the forme cylinder 9; 10 is connected to this coupling movement.
- a gear 45 consisting of a housing 33 and spur gears 34 and 35, is fixedly connected to the fluid-operated cylinder 30 and is supported on this on the stationary machine frame 31 from.
- a bolt 36 is screwed in the bearing block 17 and is supported with its head 37 on the spur gear 35 from.
- the working cylinder 30 presses the function of the side registering, ie force or Anstelldruck of the working cylinder 30 in the direction 27 - Anstellraum -, the bearing block 17 via the pivot bearing 32 in the direction 27 and thus brings the head 37 on the spur gear 35 without play to the plant.
- This spur gear 35 can be moved axially when turning over an example configured as a fine thread in the housing 33 arranged threaded 38, ie in the direction 26 and 27 by the pressure of the working cylinder 30 in the direction 27, the flanks of the thread 38 are pressed together without play. Each rotation of the spur gear 35 is thus immediately and without play in an axial movement of the bearing block 17 and the forme cylinder 9; 10 implemented.
- the spur gear 35 is first rotated by the servomotor 39 at a high speed to shorten the travel time. From this high rotational speed results in a high speed, a so-called. Positioning, the axial movement of the bearing block 17. With increasing rotation of the spur gear 35 is the Page registers corrected, ie the deviations of the registration marks are reduced, so that the traversing path to be covered for correcting the register deviations becomes smaller. Thus, the speed of rotation of the spur gear 35 is reduced due to the registered reduced deviations of the registration crosses and the reduced travel path.
- the high speed of rotation of the spur gear 35 at the beginning of the correction of the side register, due to the high deviations of the register marks, is thus gradually reduced as a result of the increasing improvement of the side register until the final correction of these register deviations.
- the speed of the servomotor 39 is thus variable and / or different adjustable.
- the center position of the spur gear 35 is registered via a switch 40, the end positions of the travel from the non-contact switches 41 and 42.
- the spur gear 35 thus represents an adjustable stop.
- the device should not be limited only to the use of form cylinders. It is also possible to apply the device in addition to transfer cylinders to perform a quick cylinder change or quick change arranged on the transfer cylinder blanket cylinder sleeve.
- the object is achieved, a simple, accurate Axialregisterung with a fast coupling movement of the cylinder, in particular the forming or transfer cylinder to connect.
- the before adjusted positions of the axial register remain, unlike a controlled axis, received.
- a controlled axis would have, after completion of the coupling movement, the previously set positions again approach with the required accuracy, which costs time.
- variable speed for correction of the register deviations should not be limited to a servomotor. It is also possible according to the DE 100 08 215 A1 used controlled axis, such as a motor-driven spindle or a linear drive to operate for correcting the side register with variable and / or different speeds.

Description
Die Erfindung betrifft ein Druckwerk einer Rotationsdruckmaschine nach dem Oberbegriff von Anspruch 1.The invention relates to a printing unit of a rotary printing press according to the preamble of
Beim Drucken von mehrfarbigen Produkten mit bekanntlich mehr als einem Druckwerk kommt es darauf an, dass die einzelnen Druckbilder deckungsgleich übereinander liegen. Während das sogenannte Umfangsregister über den Antrieb der Formzylinder geregelt wird, wird das Seitenregister durch axiales Verschieben des Formzylinders korrigiert.When printing multi-color products with more than one printing unit, it is important that the individual print images are congruent. While the so-called circumferential register is controlled by the drive of the forme cylinder, the side register is corrected by axial displacement of the forme cylinder.
Aus der
Die vorliegende Erfindung hat es sich zur Aufgabe gemacht, ein Druckwerk zu schaffen, welches ein einfaches und trotzdem genaues Verstellen des Seitenregisters ermöglicht und außerdem eine schnelle größere Axialbewegung des Formzylinders für Entkopplungszwecke zuläßt.The present invention has set itself the task of creating a printing unit, which allows a simple yet accurate adjustment of the side register and also allows a fast larger axial movement of the forme cylinder for decoupling purposes.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des unabhängigen Patentanspruches 1 gelöst. Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.This object is achieved with the features of
Vorteil ist, dass eine geregelte Achse vermieden wird, dadurch werden die Kosten erheblich reduziert. Eine schnelle Koppelbewegung des Formzylinders in Achsrichtung ist trotzdem möglich.The advantage is that a controlled axis is avoided, thereby the costs are considerably reduced. A fast coupling movement of the forme cylinder in the axial direction is still possible.
Bedeutungsvoll ist, dass eine schnelle Koppelbewegung des Druckzylinders bzw. Formzylinders mittels dem druckmittelbetriebenen Arbeitszylinders durchführbar ist. Besonders zu erwähnen ist, dass mittels dem einstellbaren Anschlag ein schnelles Verbringen des Druckzylinders bzw. Formzylinders in eine seitenregistergerechte Position bewerkstelligbar ist. Somit ist mit der Erfindung eine schnelle Koppelbewegung und ein schnelles seitenregistergerechtes Positionieren des Druckzylinders bzw. Formzylinders realisiert, d.h. die Vorteile einer schnellen Koppelbewegung durch einen druckmittelbetriebenen Arbeitszylinder werden mit den Vorteilen einer schnellen Verbringung in eine seitenregistergerechte Position mittels des einstellbaren Anschlages verbunden. Durch den Anstelldruck des druckmittelbetriebenen Arbeitszylinders an den Anschlag ist dieser spielfrei, d.h. der Lagerbock liegt durch den Anstelldruck des druckmittelbetriebenen Arbeitszylinder spielfrei am einstellbaren Anschlag an. Durch den einstellbaren Anschlag wird der Formzylinder über seine Lagerböcke verschoben und somit mit dem einstellbaren Anschlag und mit Hilfe einer Steuerung und einer Abtastoptik in Form einer Kamera das Seitenregister geregelt. Der druckmittelbetriebene Arbeitszylinder verschiebt über die antriebsseitige Lagerung den Formzylinder bei der Koppelbewegung.It is significant that a fast coupling movement of the printing cylinder or forme cylinder by means of the fluid-operated working cylinder is feasible. It should be mentioned in particular that by means of the adjustable stop a rapid movement of the printing cylinder or forme cylinder into a position suitable for the page register can be accomplished. Thus, with the invention, a fast coupling movement and a fast page register right positioning of the impression cylinder or cylinder is realized, i. the advantages of a fast coupling movement by a fluid operated cylinder are combined with the advantages of a quick shipment in a page register position by means of the adjustable stop. By the contact pressure of the fluid-operated working cylinder to the stop this is free of play, i. the bearing block is due to the contact pressure of the fluid-operated cylinder working at the adjustable stop. Due to the adjustable stop the form cylinder is moved over its bearing blocks and thus regulated with the adjustable stop and with the aid of a controller and a scanning optics in the form of a camera, the page register. The fluid-operated cylinder moves on the drive-side mounting the forme cylinder in the coupling movement.
Bedeutungsvoll ist, dass mittels des erfindungsgemäßen Druckwerks die vorher eingestellten Positionen des Axialregisters bzw. Seitenregisters, im Gegensatz zu einer Vorrichtung zur Einstellung des Seitenregisters mit einer geregelten Achse, bei einem Entkoppeln des Formzylinders erhalten bleiben. Eine geregelte Achse müßte ja, nach Abschluss der Koppelbewegung, die vorher eingestellten Positionen wieder mit der erforderlichen Genauigkeit anfahren. Dies kostet Zeit bzw. erhöht den Zeitaufwand für das Ankoppeln und das genaue Positionieren des Formzylinders an voreingestellte Positionen.It is significant that by means of the printing unit according to the invention, the previously set positions of the axial register or page register, in contrast to a device for adjusting the side register with a controlled axis, remain in a decoupling of the forme cylinder. After completion of the coupling movement, a controlled axis would have to approach the previously set positions again with the required accuracy. This costs time or increases the time required for coupling and exact positioning of the forme cylinder at preset positions.
Ein weiterer Nachteil des Standes der Technik ist, dass diese geregelten Achsen während der Einstellung des Seitenregisters mit einer konstanten Geschwindigkeit fahren. Die Positioniergeschwindigkeit wird dabei so gering gewählt, dass bei laufend notwendigen Positionierungen, d.h. Korrekturen des Seitenregisters, im Druckbetrieb keine nachteiligen Erscheinungen im Druckbild erkennbar sind. Dies führt bei Druckbeginn dazu, dass die dann oft noch vergleichsweise großen Verfahrwege lange Zeit benötigen und dabei viele schlechte Druckexemplare entstehen.Another disadvantage of the prior art is that these controlled axles travel at a constant speed during adjustment of the side register. The positioning speed is chosen to be so low that in the case of necessary positioning, ie corrections of the page register, no disadvantageous phenomena in the printed image can be detected in the printing operation. This leads Start of printing that then often comparatively large travels require a long time and thereby many bad printed copies arise.
Bedeutungsvoll ist, dass mittels des erfindungsgemäßen Druckwerks eine Stellvorrichtung geschaffen wird, die ein schnelles und einfaches Einstellen des Seitenregisters zulässt. Die Vorrichtungsmerkmale sind im unabhängigen Patentanspruch 1 wiedergegeben. Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.It is significant that by means of the printing unit according to the invention, an adjusting device is provided, which allows a quick and easy setting of the page register. The device features are given in
Die vorliegende erfindungsgemäße Vorrichtung weist einen Positionierantrieb auf, der mit unterschiedlichen Geschwindigkeiten die zur Korrektur des Seitenregisters erforderlichen Positionierungen durchführen kann und somit in der Lage ist, bei großen notwendigen Verfahrungen größere Positioniergeschwindigkeiten zu nutzen. Da bei großen Registerabweichungen die Druckexemplare als schlecht eingestuft werden müssen, ist eine große Positioniergeschwindigkeit für das Druckbild nicht weiter nachteilig. Bedeutungsvoll ist jedoch, dass mittels einer großen Positioniergeschwindigkeit die Zeit für das Ausregeln der Registerabweichung, insbesondere das Ausregeln der Abweichung des Seitenregisters, erheblich verkürzt wird.
Weiterhin ist die für das Druckbild unschädliche Positioniergeschwindigkeit abhängig von der Drehzahl des Plattenzylinders. Je schneller dieser dreht, desto schneller darf positioniert werden. Somit ist man mit der erfindungsgemäßen Vorrichtung in der Lage, immer optimal auf die aktuelle Maschinengeschwindigkeit bezogene Positioniergeschwindigkeiten zu nutzen, während übliche Positioniersysteme immer auf eine bestimmte Zylinderdrehzahl ausgelegt werden müssen und bei niedrigerer Zylinderdrehzahl dann zu schnell positionieren.
Dies ist insbesondere wichtig bei formatvariablen Druckmaschinen, da unterschiedliche Plattenzylinderumfänge bei gleichbleibender maximaler Bahngeschwindigkeit unterschiedliche Plattenzylinderdrehzahlen erzwingen und sonst die Positionierung bei den meisten Zylinderumfängen nicht optimal schell erfolgt.The present inventive device has a positioning drive, which can perform at different speeds required for the correction of the page register positioning and thus is able to use larger positioning speeds in large necessary procedures. Since with large register deviations the printed copies must be classified as bad, a large positioning speed for the printed image is not disadvantageous. It is significant, however, that by means of a large positioning speed, the time for the correction of the register deviation, in particular the compensation of the deviation of the page register, is considerably shortened.
Furthermore, the harmless for the print image positioning speed depends on the speed of the plate cylinder. The faster it turns, the faster it can be positioned. Thus, with the device according to the invention, it is possible to always optimally use positioning speeds related to the current machine speed, while conventional positioning systems always have to be designed for a specific cylinder speed and then position too quickly at lower cylinder speeds.
This is particularly important in variable-format printing machines, since different Plattenzylinderumfänge force at constant maximum web speed different plate cylinder speeds and otherwise the positioning is not ideal schell done at most Zylinderumfängen.

Die
Wie bereits erwähnt, kommt es beim Bedrucken der Papierbahn 13 nun darauf an, dass die vier verschiedenfarbigen Druckbilder deckungsgleich übereinander liegen. Zu diesem Zweck werden von den Formzylindern 9; 10 sogenannte Passerkreuze zusammen mit dem Druckbild über die Übertragungszylinder 11; 12 auf die Papierbahn 13 übertragen. Bei einem einwandfreien Druck liegen diese Passerkreuze aus jedem Druckwerk 2 bis 5 deckungsgleich übereinander. Abweichungen davon werden von Abtastoptiken 15; 16, beispielsweise Kameras oder Registerkameras, erfaßt und über eine Steuerung 43 in Regelschritte umgesetzt, die einer Steuerung 44 zur Registerung zugeführt werden. Die Registerregelung am Umfang des Formzylinders 9; 10 geschieht über den Antrieb, insbesondere über Einzelantriebsmotoren, die Registerregelung der Formzylinder 9; 10 in Achsrichtung, d.h. die Regelung des Seitenregisters, soll im folgenden genauer beschrieben werden.As already mentioned, when printing on the paper web 13, it now depends on the four differently colored printed images being congruent to one another. For this purpose, of the form cylinders 9; 10 so-called registration crosses together with the printed image on the
Der Aufbau der Formzylinderlagerung wird anhand der
Wie gezeigt, ist der Lagerbock 17 auf Führungen 24 und der Lagerbock 18 auf Führungen 25 gelagert. Somit ist der Lagerbock 17 in Richtung 26 bzw. 27 und der Lagerbock 18 in Richtung 28 bzw. 29 verschiebbar. Der Lagerbock 17 ist als Festlager, der Lagerbock 18 als Loslager ausgebildet, das eine gewisse Verschiebung in den Richtungen 26 und 27 zulässt. Ein druckmittelbetriebener Arbeitszylinder 30, beispielsweise ein Pneumatikzylinder oder Hydraulikzylinder, ist einerseits mit einem ortsfesten Maschinengestell 31 verbunden, andererseits mit der Kolbenstange über ein Gelenklager 32 am Lagerbock 17 befestigt.As shown, the bearing
Zum Ausbau des Formzylinders 9; 10 oder einer Formzylinderhülse von der Oberfläche des Formzylinders 9; 10 muß bekanntlich die Achse 20 des Zylinders vom Lagerbock 18 getrennt werden. Zu diesem Zweck wird, wie in
Die
Sind die Abweichungen der Passerkreuze untereinander beispielsweise bei Druckbeginn zu hoch, dann muss ein größerer Verfahrweg zur Korrektur der Registerabweichungen zurückgelegt werden, so dass zur zeitlichen Verkürzung des Verfahrvorganges das Stirnrad 35 vom Stellmotor 39 zunächst mit einer hohen Geschwindigkeit verdreht wird. Aus dieser hohen Verdrehgeschwindigkeit resultiert eine hohe Geschwindigkeit, eine sog. Positioniergeschwindigkeit, der Axialbewegung des Lagerbockes 17. Mit zunehmender Verdrehung des Stirnrades 35 wird das Seitenregister korrigiert, d.h. die Abweichungen der Passerkreuze verringern sich, so dass der zurückzulegende Verfahrweg zur Korrektur der Registerabweichungen geringer wird. Somit wird die Geschwindigkeit der Verdrehung des Stirnrades 35 bedingt durch die registrierten verminderten Abweichungen der Passerkreuze und des verminderten Verfahrweges verringert. Die zu Beginn der Korrektur des Seitenregisters hohe Geschwindigkeit der Verdrehung des Stirnrades 35, bedingt durch die hohen Abweichungen der Passerkreuze, wird somit infolge der zunehmenden Verbesserung des Seitenregisters bis zur endgültigen Korrektur dieser Registerabweichungen schrittweise verringert. Die Geschwindigkeit des Stellmotors 39 ist somit variabel und/oder unterschiedlich einstellbar.If the deviations of the register crosses are too high, for example at the beginning of printing, then a larger travel path must be covered to correct the register deviations, so that the
Die Mittelstellung des Stirnrades 35 wird über einen Schalter 40 registriert, die Endlagen des Stellweges von den berührungslosen Schaltern 41 und 42. Das Stirnrad 35 stellt somit einen verstellbaren Anschlag dar.The center position of the
Beim oben beschriebenen Abkoppeln des Formzylinders 9; 10 vom als Loslager ausgestalteten Lagerbock 18 bewegt sich der Pneumatikzylinder 30 in Richtung 26 und der Bolzen 36 mit dem Kopf 37 fährt in die Stellung 36' bzw. 37',
Als Alternative kann, nicht näher dargestellt, anstelle des ortsfesten Maschinengestelles 31 auch ein verstellbarer Schlitten gemäß der
Die Vorrichtung soll sich nicht nur auf den Einsatz an Formzylindern beschränken. Es ist auch möglich die Vorrichtung zusätzlich an Übertragungszylindern anzuwenden, um einen schnellen Zylinderwechsel oder schnellen Wechsel einer auf dem Übertragungszylinder angeordneten Gummituchzylinderhülse durchzuführen.The device should not be limited only to the use of form cylinders. It is also possible to apply the device in addition to transfer cylinders to perform a quick cylinder change or quick change arranged on the transfer cylinder blanket cylinder sleeve.
Durch dieses Ausführungsbeispiel ist damit die Aufgabe gelöst, eine einfache, genaue Axialregisterung mit einer schnellen Koppelbewegung des Zylinders, insbesondere des Form- oder Übertragungszylinders, zu verbinden. Die vorher eingestellten Positionen des Axialregisters bleiben, anders als bei einer geregelten Achse, erhalten. Eine geregelte Achse müsste ja, nach Abschluss der Koppelbewegung, die vorher eingestellten Positionen wieder mit der erforderlichen Genauigkeit anfahren, was Zeit kostet.By this embodiment, the object is achieved, a simple, accurate Axialregisterung with a fast coupling movement of the cylinder, in particular the forming or transfer cylinder to connect. The before adjusted positions of the axial register remain, unlike a controlled axis, received. A controlled axis would have, after completion of the coupling movement, the previously set positions again approach with the required accuracy, which costs time.
