Description

Die Erfindung betrifft ein Verfahren zum Voreinstellen der mit je einer Markierung versehenen Formzylinder von Mehrfarbenrollenrotationsdruckmaschinen, bei dem die Formzylinder zum,Einstellen ihrer Ausgangsstellungen entsprechend der Lage ihrer Markierungen zu gestellfesten Markierungen von ihren Antrieben abgekuppelt und anschließend entsprechend der Länge der Bahn zwischen der jeweiligen gestellfesten Markierung und der Markierung des ersten Formzylinders wieder an ihre Antriebe angekuppelt werden, sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for presetting the forme cylinders, each provided with a mark, of multi-color web-fed rotary printing presses, in which the forme cylinders are decoupled from their drives to markings fixed to the frame for setting their starting positions according to the position of their markings, and then according to the length of the web between the respective markings fixed to the frame and the marking of the first forme cylinder are coupled again to their drives, and a device for carrying out this method.

Bei einem aus der DE-OS 27 53 433 bekannten Verfahren dieser Art werden zunächst die Markierungen der von ihrer Hauptantriebswelle abgekuppelten Formzylinder zur Einstellung ihrer Ausgangsstellungen mit gestellfesten Markierungen zur Deckung gebracht und anschließend werden die auf den ersten Formzylinder folgenden Formzylinder der Reihe nach aus ihren Ausgangsstellungen.relativ zu dem jeweils vorherigen Formzylinder um einen Winkel verdreht, der sich aus dem Quotienten des Restes der durch den Formzylinderumfang geteilten, zwischen jeweils zwei Markierungen liegenden Bahnlänge und des Zylinderumfangs ergibt. Der jeweils in dieser Weise verdrehte Formzylinder wird sodann wieder an die Hauptantriebswelle angekuppelt. Zur Ermittlung und Anzeige der Verdrehwinkel ist ein mit der Hauptantriebswelle verbindbares Gerät vorgesehen.In a method of this type known from DE-OS 27 53 433, the markings of the forme cylinder uncoupled from their main drive shaft are brought to cover their initial positions with marks fixed to the frame, and then the forme cylinders following the first forme cylinder are sequentially removed from their initial positions . rotated relative to the respective previous forme cylinder by an angle which results from the quotient of the remainder of the path length divided by the forme cylinder circumference and lying between two markings and the cylinder circumference. The forme cylinder rotated in this way is then coupled again to the main drive shaft. A device that can be connected to the main drive shaft is provided for determining and displaying the angle of rotation.

Bei einem aus der DE-OS 29 30 438 bekannten, sehr ähnlichen Verfahren wird zur Einstellung des Registers zwischen zwei Formzylindern der in Bahnlaufrichtung zweite Formzylinder eingeschaltet und die Winkellage des Formzylinders beim.Vorbeilauf seiner zugehörigen Registermarke an seiner Abtastvorrichtung als Zylinderimpuls gespeichert. Anschließend wird der Formzylinder des zweiten Druckwerks ab- und der erste Formzylinder angeschaltet und der zwischen dem Auftreten des Zylinderimpulses und dem Erfassen der Registermarke des ersten Formzylinders an der Abtastvorrichtung des zweiten Formzylinders zurückgelegte Bahnweg wird als Registerstellbefehl verwendet.In a very similar method known from DE-OS 29 30 438, to set the register between two forme cylinders, the second forme cylinder in the web running direction is switched on and the angular position of the forme cylinder is saved as a cylinder impulse on its scanning device on its scanning device. The forme cylinder of the second printing unit is then switched off and the first forme cylinder is switched on, and the path traveled between the occurrence of the cylinder pulse and the detection of the register mark of the first forme cylinder on the scanning device of the second forme cylinder is used as a register setting command.

Nach beiden Verfahren werden die jeweiligen Verdrehwinkel in digitalisierter Form erfaßt, so daß beispielsweise Mikrocomputer zur Steuerung verwendet werden können.According to both methods, the respective angles of rotation are recorded in digitized form so that, for example, microcomputers can be used for control.

Beide Verfahren zur Registervoreinstellung sind verhältnismäßig aufwendig, weil die Ankupplung der Formzylinder an ihre Antriebe erst erfolgen kann, nachdem die jeweiligen Verdrehwinkel rechnerisch ermittelt worden sind.Both methods of register presetting are relatively complex because the coupling of the forme cylinders to their drives can only take place after the respective angles of rotation have been determined by calculation.

Aufgabe der Erfindung ist es daher, ein einfacheres Verfahren zur Voreinstellung des Registers der Formzylinder zu schaffen.The object of the invention is therefore to provide a simpler method for presetting the register of the forme cylinders.

Erfindungsgemäß wird diese Aufgabe bei einem Verfahren der eingangs angegebenen Art dadurch gelöst, daß die zu bedruckende Bahn in die Druckmaschine eingefahren und mit den Registermarken der Druckwerke bedruckt wird, daß die Formzylinder der dem ersten Druckwerk folgenden Druckwerke in dem Zeitpunkt von ihren Antrieben abgekuppelt werden, in dem die von diesen gedruckten Registermarken von einem dem jeweiligen Formzylinder zugeordneten, eine gestellfeste Markierung bildenden Fototaster erfaßt werden, und daß die Formzylinder der Reihe nach wieder an ihre Antriebe angekuppelt werden, wenn der jeweilige, diesen zugeordnete Fototaster die Druckmarke des Formzylinders des jeweils vorhergehenden Druckwerks erfaßt. Nach dem erfindungsgemäßen Verfahren kann in einfacher Weise und mit hoher Genauigkeit eine Voreinstellung der Register der Formzylinder erfolgen. Zunächst ist es lediglich erforderlich, die dem ersten Formzylinder folgenden Formzylinder dadurch in ihre Ausgangsstellung zu bringen, daß deren Registermarken zu den zugeordneten Fototastern ausgerichtet werden, was automatisch erfolgen kann, ohne daß die Registermarken in bestimmter Weise relativ zu gestellfesten Registermarken ausgerichtet werden müßten. Die abgekuppelten Formzylinder werden in dem Moment wieder an ihre Antriebe angekuppelt, wenn die diesen zugeordneten Fototaster die von dem Formzylinder des jeweils vorhergehenden Druckwerks gedruckte Registermarke erfassen. Das erfindungsgemäße Verfahren läßt sich ohne rechnerische Manipulationen und aufwendige Steuereinrichtungen durchführen.According to the invention, this object is achieved in a method of the type specified at the outset in that the web to be printed is moved into the printing press and printed with the register marks of the printing units, and the form cylinders of the printing units following the first printing unit are uncoupled from their drives at the time, in which the register marks printed by these are detected by a photo button assigned to the respective forme cylinder, forming a frame-fixed marking, and in that the forme cylinders are coupled in turn to their drives when the respective, assigned photo button is the print mark of the forme cylinder of the previous one Printing unit detected. According to the method according to the invention, the registers of the forme cylinders can be preset in a simple manner and with high accuracy. First of all, it is only necessary to bring the forme cylinders following the first forme cylinder into their starting position by aligning their register marks with the assigned photo sensors, which can be done automatically without the register marks having to be aligned in a certain way relative to register marks fixed to the frame. The uncoupled forme cylinders are coupled to their drives again when the photo sensors assigned to them register the register mark printed by the forme cylinder of the previous printing unit to capture. The method according to the invention can be carried out without arithmetic manipulations and complex control devices.

Nach einer Fortbildung des erfindungsgemäßen Verfahrens läßt sich zusätzlich dadurch Makulatur einsparen, daß die dem Formzylinder des ersten Druckwerks folgenden Formzylinder von ihren Antrieben abgekuppelt werden, wenn die von diesen gedruckten Registermarken von den zugehörigen Fototastern erfaßt und wieder angekuppelt werden, wenn die Fototaster die nachfolgenden Registermarken des ersten Formzylinders erfassen. Nach dieser Ausgestaltung des erfindungsgemäßen Ver- - fahrens läßt sich eine Voreinstellung der Formzylinder nur bei einem Durchlauf der Bahn erreichen.According to a further development of the method according to the invention, waste can also be saved in that the forme cylinders following the forme cylinder of the first printing unit are uncoupled from their drives when the register marks printed by them are detected by the associated photo sensors and recoupled when the photo buttons the subsequent register marks of the first forme cylinder. According to this embodiment of the method according to the invention, the forme cylinders can only be preset when the web is running.

In besonders günstiger Weise läßt sich das erfindungsgemäße Verfahren vorrichturigsmäßig dadurch ausführen, daß zum An- und Abkuppeln der Formzylinder elektrisch betätigbare Lamellen- oder Zahnkupplungen vorgesehen sind.In a particularly favorable manner, the method according to the invention can be carried out in accordance with the device in that electrically operable plate or toothed clutches are provided for coupling and uncoupling the forme cylinders.

Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnung, in deren einziger Figur eine Vierfarbendruckmaschine in Seitenansicht schematisch dargestellt ist, näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawing, in the single figure of which a four-color printing machine is schematically shown in side view.

Von der Vorratsrolle 2 wird die zu bedruckende Bahn 3 abgezogen und den Druckwerken 11, 12, 13, 14 der Mehrfarbenrollenrotationsdruckmaschine 1 zugeführt. Die einzelnen Druckwerke 11, 12, 13, 14 sind mit Formzylindern 4 und Gegendruckzylindern 5 versehen. Die bedruckte Bahn wird über bekannte und nicht bezeichnete Leitwalzen zugeführt und in bekannter Weise getrocknet. Die Farbwerke, durch die die Formzylinder 4 eingefärbt werden, sind der übersichtlichkeit halber weggelassen worden.The web 3 to be printed is drawn off from the supply roll 2 and fed to the printing units 11, 12, 13, 14 of the multi-color rotary printing press 1. The individual printing units 11, 12, 13, 14 are provided with forme cylinders 4 and impression cylinders 5. The printed web is fed over known and not designated guide rollers and dried in a known manner. The inking units through which the forme cylinder 4 are colored have been omitted for the sake of clarity.

Die Formzylinder 4 werden durch eine Hauptwelle 6 angetrieben, wobei die Achsen der Formzylinder 4 Kegelräder tragen, die mit den Kegelrädern 11.1 bis 14.1 kämmen. Das Kegelrad 11.1 ist unverschieblich auf der Hauptwelle 6 befestigt. Die Kegelräder 12.1 - 14.1 sind mit der Hauptantriebswelle über auf dieser verschieblichen Hohlwellen von Kupplungs-Bremseinrichtungen 22 - 24 verbunden. Die Hohlwellen können als Vielkeilwellen ausgebildet sein, so daß die Kegelräder 12.1 - 14.1 relativ zu diesen axial verschieblich, aber undrehbar sind. Die Hohlwellen tragen die Schaltlamellen 22.1 - 24.1 der aus Lamellenkupplungen gebildeten Kupplungs-Bremseinrichtungen. Zum Ankuppeln der Hohlwellen an die Hauptwelle 6 sind mit der Hauptwelle 6 Kupplungslamellen 22.2 - 24.2 drehfest verbunden. Andererseits sind Bremslamellen 22.3 - 24.3 gestellfest mit der Maschine verbunden, so daß durch entsprechendes Verschieben der Hohlwelle die mit dieser drehfest verbundenen Schaltlamellen einmal an die Kupplungslamellen der Hauptwelle 6 und zum Abbremsen und Feststellen der Formzylinder mit den gestellfesten Bremslamellen gekuppelt werden können.The forme cylinders 4 are driven by a main shaft 6, the axes of the forme cylinders 4 carrying bevel gears which mesh with the bevel gears 11.1 to 14.1. The bevel gear 11.1 is fixed immovably on the main shaft 6. The bevel gears 12.1 - 14.1 are connected to the main drive shaft by means of hollow brake shafts 22 - 24 which are displaceable on the main drive shaft. The hollow shafts can be designed as multi-spline shafts, so that the bevel gears 12.1 - 14.1 are axially displaceable but non-rotatable relative to these. The hollow shafts carry the shift plates 22.1 - 24.1 of the clutch brake devices formed from multi-plate clutches. For coupling the hollow shafts to the main shaft 6 6 clutch plates 22.2 - 24.2 are rotatably connected to the main shaft. On the other hand, brake discs 22.3 - 24.3 are fixed to the frame of the machine, so that by shifting the hollow shaft, the non-rotatably connected switching plates can be coupled to the clutch plates of the main shaft 6 and to brake and lock the forme cylinders with the fixed brake plates.

In Bahnlaufrichtung sind hinter den Gegendruckzylindern 5 der Druckwerke 12 - 14 gestellfest Fotozellen 32 - 34 angeordnet, die auf Passermarken gerichtet sind, die von den Formzylindern 4 auf die Bahn 3 gedruckt werden.In the web running direction, behind the counter-pressure cylinders 5 of the printing units 12-14, photocells 32-34 are arranged fixed to the frame and are directed at registration marks which are printed on the web 3 by the forme cylinders 4.

Die Voreinstellung der Formzylinder 4 erfolgt folgendermaßen: Die Formzylinder 4 werden zunächst ohne Rücksicht auf die Stellung Ihrer Passermarken eingebaut. Anschließend wird eine unbedruckte Bahn mit Einzugsgeschwindigkeit einlaufen gelassen und mit allen Farben angedruckt. Sobald die gedruckten Marken dercem ersten Druckwerk folgenden Druckwerke 12, 13, 14 unter den zugeordneten Fotozellen (32, 33, 34) erscheinen, werden die zugehörigen Formzylinder durch ein von der Foto- zelle abgegebenes Signal mit Hilfe der Kupplungs-Bremseinrichtungen stillgesetzt und in dieser Stellung festgehalten. In diesen Druck-ab-Stellungen sind die Formzylinder von der Bahn abgestellt, so daß diese behinderungsfrei die Druckmaschine durchlaufen kann. Durch diesen Vorgang sind alle dem Formzylinder des ersten Druckwerks folgenden Formzylinder relativ zu den zugehäigen Fotozellen und damit auch zueinander ausgerichtet.The form cylinders 4 are preset as follows: The form cylinders 4 are initially installed regardless of the position of your registration marks. An unprinted web will then run in at feed speed relaxed and printed with all colors. As soon as the printed marks dercem first printing unit following the printing units 12, 13, 14 under the associated photocells (32, 33, 34) appear to be shut down the associated form cylinder by a cell of the photo emitted signal by means of the K upplungs-braking devices and in held this position. In these print-down positions, the forme cylinders are parked on the web so that it can pass through the printing machine without hindrance. As a result of this process, all forme cylinders following the forme cylinder of the first printing unit are aligned relative to the associated photocells and thus also to one another.

Wenn nun die von dem ersten Druckwerk 11 gedruckte Passermarke unter der Fotozelle 32 des zweiten Druckwerks 12 erscheint, wird dessen Formzylinder 4 an die Hauptwelle 6 angekuppelt und gleichzeitig wieder an die Bahn angestellt. Beim Durchgang der von dem ersten Druckwerke 1.1 gedruckten Passermarke unter der Fotozelle 33 wird der Formzylinder 4 des Druckwerks 13 eingekuppelt und so fort, bis alle Formzylinder 4 mit der Hauptwelle 6 in Antriebsverbindung stehen und an die Bahn angestellt sind. Der Druck kann sogleich beginnen, d. h. die Maschine kann auf die Druckgeschwindigkeit hochlaufen, denn die Passermarken sind nun im Fangbereich der Fotozellen, so daß die. Registersteuerung wirksam werden kann.If the registration mark printed by the first printing unit 11 now appears under the photocell 32 of the second printing unit 12, its forme cylinder 4 is coupled to the main shaft 6 and at the same time again placed on the web. When the registration mark printed by the first printing unit 1.1 passes under the photocell 33, the forme cylinder 4 of the printing unit 13 is coupled in and so on until all forme cylinders 4 are in drive connection with the main shaft 6 and are in contact with the web. Printing can begin immediately. H. the machine can run up to the printing speed, because the registration marks are now in the capture area of the photocells, so that the. Register control can take effect.

Wie üblich, wird vor dem Auskuppeln auf "Druck-ab" und nach dem Einkuppeln der Formzylinder das Druckwerk auf "Druck-an" geschaltet.As usual, the printing unit is switched to "print-on" before disengaging and "after printing".

Das Vorjustieren der Formzylinder kann zum weiteren Einsparen von Makulatur auch in folgender Weise erfolgen: Die Formzylinder 4 der Druckwerke 11, 12 drucken auf die einlaufende Bahn ihre Passermarken. Erfaßt die Fotozelle 32 des Druckwerks 1.2 die von diesem gedruckte Passermarke, wird der Formzylinder des Druckwerks 12 stillgesetzt. Beim kurz darauf erfolgenden Durchlauf der von dem Druckwerk 11 gedruckten Passermarke unter die Fotozelle 32 wird der Formzylinder 4 des Druckwerks 12 schon wieder eingekuppelt. Gleichzeitig wird auch der Formzylinder 4 des Druckwerks 13 an die Hauptwelle 6 angekuppelt und beim Durchgang der von diesem gedruckten Passermarke unter der Fotozelle 33 wird der Formzylinder des Druckwerks 13 wieder stillgesetzt. Beim Durchgang der von dem ersten Druckwerk 11 gedruckten Passermarke unter der Foto-zelle 33 wird der Formzylinder 4 des Druckwerks 13 wieder eingekuppelt und gleichzeitig wird der Formzylinder 4 des Druckwerks 14 zugeschaltet. Beim Durchgang der von diesem gedruckten Passermarke durch die diesem zugeordnete-Fotozelle 34 wird der Formzylinder des Druckwerks 14 wieder stillgesetzt und erst wieder zugeschaltet, wenn die von dem Druckwerk 11 gedruckte Passermarke die Fotozelle 34 erreicht.The pre-adjustment of the forme cylinders can also be done in the following way to further reduce waste: The forme cylinders 4 of the printing units 11, 12 print their registration marks on the incoming web. If the photocell 32 of the printing unit 1.2 detects the registration mark printed by it, the forme cylinder of the printing unit 12 is stopped. When the registration mark printed by the printing unit 11 passes shortly thereafter under the photocell 32, the forme cylinder 4 of the printing unit 12 is coupled again. At the same time, the forme cylinder 4 of the printing unit 13 is also coupled to the main shaft 6 and when the registration mark printed by it passes under the photocell 33, the forme cylinder of the printing unit 13 is stopped again. When the registration mark printed by the first printing unit 11 passes under the photo cell 33, the forme cylinder 4 of the printing unit 13 is engaged again and at the same time the forme cylinder 4 of the printing unit 14 is switched on. When the registration mark printed by the latter passes through the photo cell 34 assigned to it, the forme cylinder of the printing unit 14 is stopped again and only switched on again when the registration mark printed by the printing unit 11 reaches the photo cell 34.

Wird nicht mit allen Druckwerken gedruckt, ist es lediglich erforderlich, das betreffende Druckwerk abzuschalten. In diesem Fall wird die Bahn zu dem nächsten Druckwerk geführt.If not all printing units are used for printing, it is only necessary to switch off the printing unit concerned. In this case the web is led to the next printing unit.

Durch die beschriebene Voreinstellung läßt sich eine so gute Justierung der Registermarken erreichen, daß für die Registerwalze nur ein kurzer Weg vorgesehen zu werden braucht, d. h. die zugehörige Verstellspindel kann sehr kurz ausgebildet werden.With the described presetting, such a good adjustment of the register marks can be achieved that only a short path needs to be provided for the register roller, i. H. the associated adjustment spindle can be made very short.
