Definitions
- the invention relates to methods for changing printing plates on one at least two printing units existing printing machine, the printing units at least one plate cylinder equipped with one or more printing plates have, the drive of the plate cylinder via a closed Wheel pull from the main drive of the printing press takes place, the plate cylinder in Pressure position in at least two different phases to the gear train stand and the change of the printing plates in a uniform for all printing units Pressure plate change position takes place.
- EP 0 435 413 B1 describes a method for changing printing plates known in which the used printing plates are removed one after the other. This is done by entering a plate removal position first plate cylinder from the transmission-related combination of plate cylinders or is disengaged from the wheel train of the printing press drive. The used printing plate is removed, using a single plate cylinder drive is applied. The remaining plate cylinders rotate synchronously continue until another plate cylinder is in a plate removal position arrives and the next used printing plate is removed. In this way all used printing plates are successively removed.
- the relevant plate cylinder rotated to a plate feed position and the supply of the new printing plate initiated.
- the other plate cylinders continue to rotate synchronously, with the Rotary movement now takes place in the opposite direction. Arrived another plate cylinder in a plate feed position, another printing plate fed until the automatic plate changing process is completed is.
- DE 195 11 686 A 1 describes a method for changing printing plates described, in which the removal of the used printing plates also starts successively when a printing plate unclamping position is reached and continues while the remaining plate cylinders continue synchronously rotate. With printing units with the same phase angle, the removal can the used printing plates take place simultaneously. After removing all The printing plate becomes the plate cylinder of the first printing unit in a printing plate clamping position rotated and fed a new pressure plate. First after completing this process, the plate cylinder of another printing unit rotated to a printing plate clamping position and the next Plate change process initiated. One by one this way too the new printing plates are fed to the subsequent printing units.
- the object of the invention is to develop a method by which is the automatic change of printing plates on all printing units at the same time can be done. On the use of a separate drive for the plate cylinder should be avoided. The task continues to be development a suitable device for implementing this method.
- the invention has the advantage that it is through the inventive method is now possible with little effort, the printing plates on all printing units to switch at the same time.
- the separate drive of each plate cylinder is not necessary anymore.

- At least one printing plate, not shown here, is attached to each plate cylinder 4.1, 4.2, 4.3 .
- the transfer drums 7.1, 7.2, 7.3, the pressure cylinders 6.1, 6.2, 6.3, the rubber cylinders 5.1, 5.2, 5.3 and the plate cylinders 4.1, 4.2, 4.3 with the assigned inking units 2.1, 2.2, 2.3 are connected to one another via a gear train. This is not shown in the figures. Only the drive wheel 11.1; 11.2, 11.3 of the plate cylinder 4.1, 4.2, 4.3 is indicated by a dashed line.
- Each printing unit 1.1, 1.2, 1.3 is equipped with a fully automatic printing plate changing device 12.1, 12.2, 12.3 .
- two printing units 1.2, 1.3 are equipped with a coupling 8.2, 8.3 . This is assigned to the drive shaft of the plate cylinder 4.2, 4.3 , not shown. In the exemplary embodiment, a switchable pin coupling is used.
- the clutch 8.2, 8.3 is assigned a brake, not shown here.

- a coupling half 101 is the plate cylinder drive wheel 11.1; 11.2, 11.3 (see FIG. 1) of the plate cylinder 4.2, 4.3 .
- the other coupling half 102 is firmly connected to the plate cylinder 4.2, 4.3 .
- Both coupling halves 101, 102 can be brought into engagement with one another in two snap-in positions, the snap-in position I and in the snap-in position II. This process takes place here by means of an electromagnetically actuated locking pin 9 .
- a two-part tooth coupling applied.
- the tooth pitch of such a clutch is designed so that the required snap-in positions are determined.
- the coupling 8.2, 8.3 is designed specifically for each printing unit or for each in-phase printing unit.

- the clutches 8.2, 8.3 reach their snap-in position I, ie the pressure position, the clutches 8.2, 8.3 are actuated and the connection to the drive is re-established.
- the plate cylinders 4.2, 4.3 can be separated from their drive individually or together and only then can the main drive be put into operation again. The connection to the drive is then reestablished in the printing position for each plate cylinder 4.2, 4.3 separated from the drive.
- a further embodiment of the method according to the invention differs from the above-mentioned form in that the plate cylinders 4.2, 4.3 are each separated from the drive when a uniform position for the wheel train which can be determined for all plate cylinders 4.1, 4.2, 4.3 is reached. As in the example given above, these are braked and / or positively fixed in this position. The plate cylinders 4.1 not separated from the drive are also stopped in this definable, uniform position. After all plate cylinders 4.1, 4.2, 4.3 have reached this uniform position relative to the gear train, the connection to the drive is restored. The plate cylinders 4.1, 4.2, 4.3 are brought into the pressure plate change position and the pressure plates are changed at the same time.
- the plate cylinders 4.2, 4.3 are separated from their drive. In the position relative to the gear train, which the uncoupled plate cylinder 4.1 takes or which the decoupled plate cylinder 4.1 takes , the connection to the gear train is re-established for the decoupled plate cylinders 4.2, 4.3 . This means that the uncoupled plate cylinders 4.2, 4.3 are switched on again in such a way that all plate cylinders 4.1, 4.2, 4.3 now assume a uniform position with respect to the gear train. The plate cylinders 4.1, 4.2, 4.3 are now brought into the printing plate change position and stopped there. Then the printing plates are changed as described above.

Description
Die Erfindung betrifft Verfahren zum Wechseln von Druckplatten an einer aus mindestens zwei Druckwerken bestehenden Druckmaschine, wobei die Druckwerke mindestens einen mit einer oder mehreren Druckplatten bestückten Plattenzylinder aufweisen, der Antrieb der Plattenzylinder über einen geschlossenen Räderzug vom Hauptantrieb der Druckmaschine erfolgt, die Plattenzylinder in Druckstellung in mindestens zwei verschiedenen Phasenlagen zum Räderzug stehen und der Wechsel der Druckplatten in einer für alle Druckwerke einheitlichen Druckplattenwechselstellung erfolgt.The invention relates to methods for changing printing plates on one at least two printing units existing printing machine, the printing units at least one plate cylinder equipped with one or more printing plates have, the drive of the plate cylinder via a closed Wheel pull from the main drive of the printing press takes place, the plate cylinder in Pressure position in at least two different phases to the gear train stand and the change of the printing plates in a uniform for all printing units Pressure plate change position takes place.
Aus der EP 0 435 413 B1 ist ein Verfahren zum Auswechseln von Druckplatten bekannt, bei dem die verbrauchten Druckplatten nacheinander entfernt werden. Das erfolgt, indem beim Erreichen einer Plattenentfernungsposition ein erster Plattenzylinder aus dem getriebemäßigen Verbund der Plattenzylinder bzw. aus den Räderzug des Druckmaschinenantriebs ausgekuppelt wird. Die verbrauchte Druckplatte wird entfernt, wobei hierzu ein Plattenzylinder-Einzelantrieb angewandt wird. Die verbleibenden Plattenzylinder drehen synchron weiter, bis ein weiterer Plattenzylinder in eine Plattenentfernungsposition gelangt und die nächste verbrauchte Druckplatte entfernt wird. Auf diese Weise werden aufeinanderfolgend alle verbrauchten Druckplatten entfernt.EP 0 435 413 B1 describes a method for changing printing plates known in which the used printing plates are removed one after the other. This is done by entering a plate removal position first plate cylinder from the transmission-related combination of plate cylinders or is disengaged from the wheel train of the printing press drive. The used printing plate is removed, using a single plate cylinder drive is applied. The remaining plate cylinders rotate synchronously continue until another plate cylinder is in a plate removal position arrives and the next used printing plate is removed. In this way all used printing plates are successively removed.
Nach dem Entfernen der letzten Druckplatte wird der betreffende Plattenzylinder in eine Plattenzuführposition gedreht und die Zufuhr der neuen Druckplatte eingeleitet. Die anderen Plattenzylinder drehen synchron weiter, wobei die Drehbewegung nunmehr in entgegengesetzter Richtung erfolgt. Gelangt ein weiterer Plattenzylinder in eine Plattenzuführposition, wird eine weitere Druckplatte zugeführt, bis der automatische Plattenwechselvorgang abgeschlossen ist.After removing the last printing plate, the relevant plate cylinder rotated to a plate feed position and the supply of the new printing plate initiated. The other plate cylinders continue to rotate synchronously, with the Rotary movement now takes place in the opposite direction. Arrived another plate cylinder in a plate feed position, another printing plate fed until the automatic plate changing process is completed is.
In der DE 195 11 686 A 1 wird ein Verfahren zum Wechseln von Druckplatten beschrieben, bei dem das Entfernen der verbrauchten Druckplatten ebenfalls nacheinander beim Erreichen einer Druckplattenausspannposition beginnt und fortgesetzt wird, während die verbleibenden Plattenzylinder synchron weiter drehen. Bei Druckwerken mit einem gleichen Phasenwinkel kann das Entfernen der verbrauchten Druckplatten gleichzeitig erfolgen. Nach dem Entfernen aller Druckplatten wird der Plattenzylinder des ersten Druckwerkes in eine Druckplatten-Einspannposition gedreht und eine neue Druckplatte zugeführt. Erst nach Abschluss dieses Vorganges wird der Plattenzylinder eines weiteren Druckwerkes in eine Druckplatten-Einspannposition gedreht und der nächste Plattenwechselvorgang eingeleitet. Nacheinander werden auf diese Weise auch die neuen Druckplatten der nachfolgenden Druckwerke zugeführt.DE 195 11 686 A 1 describes a method for changing printing plates described, in which the removal of the used printing plates also starts successively when a printing plate unclamping position is reached and continues while the remaining plate cylinders continue synchronously rotate. With printing units with the same phase angle, the removal can the used printing plates take place simultaneously. After removing all The printing plate becomes the plate cylinder of the first printing unit in a printing plate clamping position rotated and fed a new pressure plate. First after completing this process, the plate cylinder of another printing unit rotated to a printing plate clamping position and the next Plate change process initiated. One by one this way too the new printing plates are fed to the subsequent printing units.
Die oben beschriebenen Lösungen haben den Nachteil, dass das Wechseln der Druckplatten nicht an allen Plattenzylindern gleichzeitig erfolgen kann. Weiterhin sind die erforderlichen Vorrichtungen sehr aufwendig, da in jedem Fall ein separater Antrieb des betreffenden Plattenzylinders erforderlich ist.The solutions described above have the disadvantage that changing the Printing plates cannot be done on all plate cylinders at the same time. Farther the necessary devices are very complex, since in any case separate drive of the plate cylinder in question is required.
Aus der EP 0 533 307 B1 ist eine Lösung bekannt geworden, bei der zum Wechsel der Druckplatte die aktuelle Position des Plattenzylinders gespeichert und der betreffende Plattenzylinder anschließend in eine Plattenwechsel-Lage gedreht wird. Der Plattenwechsel wird durchgeführt und der Plattenzylinder in die gespeicherte Lage zurückgebracht. Im Rahmen dieser Lösung wird als Option angeführt, dieses Verfahren gleichzeitig an allen Druckwerken durchzuführen und so diese Arbeitsgänge parallel ablaufen zu lassen. Eine Vorrichtung hierzu wird nicht beschrieben.A solution has become known from EP 0 533 307 B1, in which a change is made the current position of the plate cylinder is saved on the printing plate and the plate cylinder in question is then rotated into a plate change position becomes. The plate change is carried out and the plate cylinder in the saved location returned. As part of this solution is an option stated to carry out this process simultaneously on all printing units and so to run these operations in parallel. A device for this is not described.
Nachteilig hierbei ist die aufwendige Steuerung, die für die Realisierung dieses Verfahrens erforderlich ist. Weiterhin ist auch hier zwingend eine Kupplung in Verbindung mit einem separaten Antrieb des Plattenzylinders erforderlich.The disadvantage here is the complex control required to implement this Procedure is required. Furthermore, a coupling is also mandatory here Connection with a separate drive for the plate cylinder required.
Die Aufgabe der Erfindung besteht darin, ein Verfahren zu entwickeln, durch welches der automatische Wechsel der Druckplatten an allen Druckwerk gleichzeitig erfolgen kann. Auf den Einsatz eines separaten Antriebs der Plattenzylinder soll verzichtet werden. Gegenstand der Aufgabe ist weiterhin die Entwicklung einer geeigneten Vorrichtung zur Realisierung dieses Verfahrens. The object of the invention is to develop a method by which is the automatic change of printing plates on all printing units at the same time can be done. On the use of a separate drive for the plate cylinder should be avoided. The task continues to be development a suitable device for implementing this method.

In Figur 1 sind drei Druckwerke 1.1, 1.2, 1.3 einer Bogenoffsetdruckmaschine dargestellt. Jedes der Druckwerke 1.1, 1.2, 1.3 besteht aus einem bogenführenden Druckzylinder 6.1, 6.2, 6.3, der mit je zwei bogenführenden Übergabetrommeln 7.1, 7.2, 7.3 in Wirkverbindung steht. Jedem Druckzylinder 6.1, 6.2, 6.3 ist ein Gummizylinder 5.1, 5.2, 5.3 und diesem wiederum ein Plattenzylinder 4.1, 4.2, 4.3 zugeordnet. Die Plattenzylinder 4.1, 4.2, 4.3 stehen mit einem Farbwerk 2.1, 2.2, 2.3 und einem Feuchtwerk 3.1, 3.2, 3.3 in Wirkverbindung. Auf jedem Plattenzylinder 4.1, 4.2, 4.3 ist mindestens eine hier nicht dargestellte Druckplatte angebracht.In Figure 1, three printing units 1.1, 1.2, 1.3 of a sheet-fed offset printing machine are shown. Each of the printing units 1.1, 1.2, 1.3 consists of a sheet-guiding printing cylinder 6.1, 6.2, 6.3, which is operatively connected to two sheet-carrying transfer drums 7.1, 7.2, 7.3 . A rubber cylinder 5.1, 5.2, 5.3 and, in turn, a plate cylinder 4.1, 4.2, 4.3 are assigned to each printing cylinder 6.1, 6.2, 6.3 . The plate cylinders 4.1, 4.2, 4.3 are operatively connected to an inking unit 2.1, 2.2, 2.3 and a dampening unit 3.1, 3.2, 3.3 . At least one printing plate, not shown here, is attached to each plate cylinder 4.1, 4.2, 4.3 .
Die Übergabetrommeln 7.1, 7.2, 7.3, die Druckzylinder 6.1, 6.2, 6.3, die Gummizylinder 5.1, 5.2, 5.3 und die Plattenzylinder 4.1, 4.2, 4.3 mit den zugeordneten Farbwerken 2.1, 2.2, 2.3 sind über einen Räderzug miteinander verbunden. Dieser ist in den Figuren nicht dargestellt. Lediglich das Antriebsrad 11.1; 11.2, 11.3 des Plattenzylinders 4.1, 4.2, 4.3 ist durch eine gestrichelte Linie angedeutet. The transfer drums 7.1, 7.2, 7.3, the pressure cylinders 6.1, 6.2, 6.3, the rubber cylinders 5.1, 5.2, 5.3 and the plate cylinders 4.1, 4.2, 4.3 with the assigned inking units 2.1, 2.2, 2.3 are connected to one another via a gear train. This is not shown in the figures. Only the drive wheel 11.1; 11.2, 11.3 of the plate cylinder 4.1, 4.2, 4.3 is indicated by a dashed line.
Jedes Druckwerk 1.1, 1.2, 1.3 ist mit einer vollautomatischen Druckplattenwechsel-Einrichtung 12.1, 12.2, 12.3 ausgerüstet.Each printing unit 1.1, 1.2, 1.3 is equipped with a fully automatic printing plate changing device 12.1, 12.2, 12.3 .
Von den dargestellten Druckwerken 1.1, 1.2, 1.3 sind zwei Druckwerke 1.2, 1.3 mit einer Kupplung 8.2, 8.3 ausgestattet. Diese ist der nicht dargestellten Antriebswelle des Plattenzylinders 4.2, 4.3 zugeordnet. Im Ausführungsbeispiel wird eine schaltbare Bolzenkupplung verwendet.Of the printing units 1.1, 1.2, 1.3 shown , two printing units 1.2, 1.3 are equipped with a coupling 8.2, 8.3 . This is assigned to the drive shaft of the plate cylinder 4.2, 4.3 , not shown. In the exemplary embodiment, a switchable pin coupling is used.
Der Kupplung 8.2, 8.3 ist eine hier nicht dargestellte Bremse zugeordnet. In einer anderen Ausführungsform wird eine Kupplungs-Brems-Kombination verwendet (hier nicht dargestellt).The clutch 8.2, 8.3 is assigned a brake, not shown here. In another embodiment, a clutch-brake combination is used (not shown here).
In der Figur 2 ist die Kupplung 8.2, 8.3 schematisch dargestellt. Dabei ist eine
Kupplungshälfte 101 dem Plattenzylinder-Antriebsrad 11.1; 11.2, 11.3 (siehe
hierzu Figur 1) des Plattenzylinders 4.2, 4.3 zugeordnet. Die andere Kupplungshälfte
102 ist mit dem Plattenzylinder 4.2, 4.3 fest verbunden. Beide
Kupplungshälften 101, 102 können in zwei Einrast-Stellungen, der Einrast-Stellung
I und in der Einrast-Stellung II, miteinander in Eingriff gebracht werden.
Dieser Vorgang erfolgt hier durch einen elektromagnetisch betätigbaren
Einrastbolzen 9.The coupling 8.2, 8.3 is shown schematically in FIG. A
In einer anderen Ausführung der Erfindung wird eine zweiteilige Zahnkupplung angewendet. Die Zahnteilung einer derartigen Kupplung ist so ausgeführt, dass die geforderten Einrast-Stellungen festgelegt werden.In another embodiment of the invention, a two-part tooth coupling applied. The tooth pitch of such a clutch is designed so that the required snap-in positions are determined.
In einer hier nicht dargestellten Ausführungsform ist die Kupplung 8.2, 8.3 spezifisch für jedes Druckwerk bzw. für jedes phasengleiche Druckwerk ausgebildet. Für jedes Druckwerk muss also eine Kupplung 8.2, 8.3 gefertigt werden. Bei dieser speziellen Kupplung korrespondieren die Einrast-Stellungen mit der Druckstellung und der Druckplattenwechselstellung bzw. mit der für alle Druckwerke einheitliche Stellung zum Räderzug. In an embodiment not shown here, the coupling 8.2, 8.3 is designed specifically for each printing unit or for each in-phase printing unit. A coupling 8.2, 8.3 must therefore be manufactured for each printing unit. With this special coupling, the snap-in positions correspond to the pressure position and the pressure plate change position or to the position of the gear train that is uniform for all printing units.
Es besteht aber auch die Möglichkeit, für jedes Druckwerk eine universelle Kupplung 8.2, 8.3 einzusetzen. Dabei werden mehrere Einrast-Stellungen vorgesehen. Das betrifft eine Einrast-Stellung für die Druckplattenwechselstellung und weitere Einrast-Stellungen für die Druckstellung in Abhängigkeit von der Anzahl der Phasenlagen bzw. mit einer Einrast-Stellung für die einheitliche Stellung zum Räderzug.But it is also possible to use a universal coupling 8.2, 8.3 for each printing unit. Several snap-in positions are provided. This relates to a snap-in position for the pressure plate change position and other snap-in positions for the pressure position depending on the number of phase positions or with a snap-in position for the uniform position relative to the gear train.
Mit der oben beschriebenen Einrichtung kann ein Verfahren realisiert werden, bei dem alle Plattenzylinder 4.1, 4.2, 4.3 zum Wechseln der Druckplatten in eine Druckplattenwechselstellung gebracht werden, so dass dort der Druckplattenwechsel gleichzeitig erfolgen kann.With the device described above, a method can be implemented in which all plate cylinders 4.1, 4.2, 4.3 are brought into a printing plate changing position for changing the printing plates, so that the printing plate change can take place there at the same time.
Es wird davon ausgegangen, dass die Plattenzylinder 4.1, 4.2, 4.3 in der Druckstellung, also beim bestimmungsgemäßem Betrieb der Bogenoffsetdruckmaschine, in mindestens zwei verschiedenen Stellungen zum Räderzug stehen. Diese Stellungen werden in der Regel als Phasenlagen bezeichnet.It is assumed that the plate cylinders 4.1, 4.2, 4.3 are in the printing position, that is to say when the sheet-fed offset printing press is operating as intended, in at least two different positions with respect to the wheel train. These positions are usually referred to as phase positions.
Beim Drucken selbst ist die Kupplung 8.2, 8.3 in der Einraststellung I eingerastet. Nach Erledigung des Druckauftrags werden die mit einer Kupplung 8.2, 8.3 ausgestatteten Plattenzylinder 4.2, 4.3 jeweils beim Erreichen der Druckplattenwechselstellung durch Betätigen der Kupplung 8.2, 8.3 von ihrem Antrieb getrennt. Das heißt, der Plattenzylinder 4.2, 4.3 wird außer Eingriff gebracht.When printing itself, the clutch 8.2, 8.3 is locked in the locked position I. After completion of the print job, the plate cylinders 4.2, 4.3 equipped with a clutch 8.2, 8.3 are each separated from their drive when the pressure plate change position is reached by actuating the clutch 8.2, 8.3 . That is, the plate cylinder 4.2, 4.3 is disengaged.
Weisen die Plattenzylinder 4.1, 4.2, 4.3 der Druckwerke 1.1, 1.2, 1.3 einer Bogenoffsetdruckmaschine keine gemeinsamen Phasenlagen auf, so betrifft das nur einen Plattenzylinder 4.1, der nicht vom Hauptantrieb getrennt wird. Bei Bogenoffsetdruckmaschinen 1 mit mehreren gleichen Phasenlagen betrifft das alle Plattenzylinder einer Phasenlage.If the plate cylinders 4.1, 4.2, 4.3 of the printing units 1.1, 1.2, 1.3 of a sheetfed offset printing press do not have any common phase positions, this only affects one plate cylinder 4.1 , which is not separated from the main drive. In sheet-fed offset printing presses 1 with several identical phase positions, this affects all plate cylinders in one phase position.
Immer nach der Trennung des betreffenden Plattenzylinders 4.2, 4.3 von ihrem Antrieb werden diese gebremst. Das erfolgt so, dass diese in der Druckplattenwechselstellung bleiben. Dabei kann auch zusätzlich oder an Stelle der Bremse eine formschlüssige Feststelleinrichtung eingesetzt werden. Die nicht vom Antrieb getrennten, weiterhin mit dem Hauptantrieb verbundenen Plattenzylinder 4.1 werden nach dem Auskuppeln der anderen Plattenzylinder 4.2, 4.3 in der Druckplattenwechselstellung zum Stillstand gebracht.Always after the relevant plate cylinder 4.2, 4.3 is disconnected from its drive, these are braked. This is done so that they remain in the pressure plate change position. A positive locking device can also be used in addition to or instead of the brake. The plate cylinders 4.1, which are not separated from the drive and continue to be connected to the main drive, are brought to a standstill in the printing plate change position after the other plate cylinders 4.2, 4.3 have been disengaged.
Nachdem sich nunmehr alle Plattenzylinder 4.1, 4.2, 4.3 in der Druckplattenwechselstellung befinden, wird die Verbindung zum Antrieb wieder hergestellt. Dazu wird die Kupplung 8.2, 8.3 in der Einrast-Stellung II betätigt (siehe Figur 2).After all the plate cylinders 4.1, 4.2, 4.3 are now in the pressure plate change position, the connection to the drive is restored. For this purpose, the clutch 8.2, 8.3 is actuated in the locked position II (see Figure 2 ).
Durch die vollautomatische Druckplattenwechsel-Einrichtung 12.1, 12.2. 12.3 können nunmehr an allen Druckwerken 1.1, 1.2, 1.3 die Druckplatten gleichzeitig gewechselt werden.Thanks to the fully automatic printing plate changing device 12.1, 12.2. 12.3 , the printing plates can now be changed simultaneously on all printing units 1.1, 1.2, 1.3 .
Nach dem Wechsel der Druckplatten bleiben die Plattenzylinder 4.1, 4.2, 4.3 vorerst mit dem Hauptantrieb verbunden. Beim weiteren Betrieb mit einer geringen Geschwindigkeit werden die mit der Kupplung 8.2, 8.3 ausgestatteten Plattenzylinder 4.2, 4.3 nacheinander oder gleichzeitig vom Räderzug getrennt. Erreichen die Kupplungen 8.2, 8.3 ihre Einrast-Stellung I, also die Druckstellung, werden die Kupplungen 8.2, 8.3 betätigt und die Verbindung zum Antrieb wieder hergestellt.After changing the printing plates, the plate cylinders 4.1, 4.2, 4.3 remain connected to the main drive for the time being. During further operation at a low speed, the plate cylinders 4.2, 4.3 equipped with the clutch 8.2, 8.3 are separated from the gear train in succession or simultaneously. When the clutches 8.2, 8.3 reach their snap-in position I, ie the pressure position, the clutches 8.2, 8.3 are actuated and the connection to the drive is re-established.
Alternativ dazu können auch nach dem Wechsel der Druckplatten die Plattenzylinder 4.2, 4.3 einzeln oder gemeinsam von ihrem Antrieb getrennt und erst danach der Hauptantrieb wieder in Betrieb genommen werden. Anschließend wird bei jedem vom Antrieb getrennten Plattenzylinder 4.2, 4.3 in der Druckstellung die Verbindung zum Antrieb wieder hergestellt.Alternatively, even after changing the printing plates, the plate cylinders 4.2, 4.3 can be separated from their drive individually or together and only then can the main drive be put into operation again. The connection to the drive is then reestablished in the printing position for each plate cylinder 4.2, 4.3 separated from the drive.
Eine weitere Ausführungsform des erfindungsgemäßen Verfahrens unterscheidet sich von der oben genannten Form dadurch, dass die Plattenzylinder 4.2, 4.3 jeweils beim Erreichen einer für alle Plattenzylinder 4.1, 4.2, 4.3 festlegbaren, einheitlichen Stellung zum Räderzug vom Antrieb getrennt werden. Dabei werden diese ebenso wie im oben angeführtem Beispiel gebremst und/oder formschlüssig in dieser Stellung fixiert. Die nicht vom Antrieb getrennten Plattenzylinder 4.1 werden ebenfalls in dieser festlegbaren, einheitlichen Stellung angehalten. Nachdem alle Plattenzylinder 4.1, 4.2, 4.3 diese einheitliche Stellung zum Räderzug erreicht haben, wird die Verbindung zum Antrieb wird wieder hergestellt. Die Plattenzylinder 4.1, 4.2, 4.3 werden in die Druckplattenwechselstellung gebracht und die Druckplatten gleichzeitig gewechselt.A further embodiment of the method according to the invention differs from the above-mentioned form in that the plate cylinders 4.2, 4.3 are each separated from the drive when a uniform position for the wheel train which can be determined for all plate cylinders 4.1, 4.2, 4.3 is reached. As in the example given above, these are braked and / or positively fixed in this position. The plate cylinders 4.1 not separated from the drive are also stopped in this definable, uniform position. After all plate cylinders 4.1, 4.2, 4.3 have reached this uniform position relative to the gear train, the connection to the drive is restored. The plate cylinders 4.1, 4.2, 4.3 are brought into the pressure plate change position and the pressure plates are changed at the same time.
In einer weiteren Ausführungsform werden die Plattenzylinder 4.2, 4.3 von ihrem Antrieb getrennt. In der Stellung zum Räderzug, welche der nicht abgekoppelte Plattenzylinder 4.1, einnimmt bzw. welche die nicht abgekoppelten Plattenzylinder 4.1 einnehmen, wird für die abgekoppelten Plattenzylinder 4.2, 4.3 nacheinander die Verbindung zum Räderzug wieder hergestellt. Das heißt, die abgekuppelten Plattenzylinder 4.2, 4.3 werden so wieder zugeschaltet, dass alle Plattenzylinder 4.1, 4.2, 4.3 nunmehr eine einheitliche Stellung zum Räderzug einnehmen. Die Plattenzylinder 4.1, 4.2, 4.3 werden nun in die Druckplattenwechselstellung gebracht und dort angehalten. Danach erfolgt der Wechsel der Druckplatten wie oben beschrieben. In a further embodiment, the plate cylinders 4.2, 4.3 are separated from their drive. In the position relative to the gear train, which the uncoupled plate cylinder 4.1 takes or which the decoupled plate cylinder 4.1 takes , the connection to the gear train is re-established for the decoupled plate cylinders 4.2, 4.3 . This means that the uncoupled plate cylinders 4.2, 4.3 are switched on again in such a way that all plate cylinders 4.1, 4.2, 4.3 now assume a uniform position with respect to the gear train. The plate cylinders 4.1, 4.2, 4.3 are now brought into the printing plate change position and stopped there. Then the printing plates are changed as described above.
