Description

Die Erfindung betrifft ein Verfahren zum Einstellen der Berührung zweier im Abstand zueinander verstellbarer Walzen eines Druckwerkes einer Rotationsdruckmaschine.The invention relates to a method for adjusting the contact between two rollers of a printing unit of a rotary printing press that are adjustable at a distance from one another.

In Farb- und Feuchtwerken von Rotationsdruckmaschinen sind in größerer Anzahl Walzen angeordnet, die zu benachbarten Walzen im Abstand einstellbar sind. Dies sind zum Beispiel die Farb- oder Feuchtauftragswalzen, die mit bestimmten Einstellungen am Formzylinder und an Reibzylindern anliegen.In the inking and dampening units of rotary printing presses, a large number of rollers are arranged which can be set at a distance from adjacent rollers. These are, for example, the inking or dampening application rollers, which are in contact with the form cylinder and distribution cylinders with certain settings.

Bekannt ist hierfür die Einstellung nach der Abdruckbreite. Es wird auf beide Seiten der Walzen gelbe Farbe aufgetragen und durch mehrere Umdrehungen egalisiert. Dann wird das Druckwerk für etwa 15 Sekunden angehalten. Beim nachfolgenden Weiterdrehen der Walzen wird die Abdruckbreite in Form zweier Striche sichtbar. Dieser Vorgang wird bei verschiedenen Walzenzustellungen solange wiederholt, bis die beiden Striche parallel und im gewünschten Abstand voneinander stehen. Diese Einstellung ist an sich zeitaufwendig und schlägt bei der hohen Zahl auszuführender Einstellungen einer Druckmaschine enorm zu Buche.The setting according to the impression width is known for this. Yellow paint is applied to both sides of the rollers and leveled by several turns. Then the printing unit is stopped for about 15 seconds. When the rollers continue to rotate, the width of the impression becomes visible in the form of two lines. This process is repeated with different roller feeds until the two lines are parallel and at the desired distance from each other. This setting is time-consuming in itself and has an enormous impact on the large number of settings to be carried out on a printing press.

Es ist weiterhin ein Gerät bekannt, mit dem die Walzeneinstellung über den Anstelldruck vorgenommen wird. Hierzu wird in den Walzenspalt nacheinander auf beiden Seiten der Walzen eine flexible Lasche eingeführt. Diese Lasche darf aber während des Meßvorgangs nicht gebogen werden, da sich ansonsten Meßwertverfälschungen einstellen. Diese Bedingung ist aber aufgrund der engen Bauweise der Farb- und Feuchtwerke bei den meisten Meßstellen nicht erfüllbar.A device is also known with which the roller adjustment is carried out via the contact pressure. For this purpose, a flexible tab is inserted one after the other into the nip on both sides of the rollers. However, this tab must not be bent during the measurement process, as this would result in falsifications of the measured values. However, due to the narrow design of the inking and dampening units, this condition cannot be met at most measuring points.

Es ist weiterhin bekannt, Walzen von einer Berührungsstellung ausgehend anzustellen. Werte für eine optimale Anstellung sind z.B. nach einer Formel zu ermitteln, die bei Böttcher, Gudehus, T., Die optimale Anstellung von Druckwalzen, Formel (10), Sonderdruck aus druck print 5/1985, druck print 6/1985 und druck print 9/1986 der Felix Böttcher GmbH Co., Köln, 1984 angegeben ist.It is also known to start rolling from a contact position. Values for optimal employment are, for example to be determined according to a formula which is used by Böttcher, Gudehus, T., Die Optimal employment of printing rollers, formula (10), special print from print print 5/1985, print print 6/1985 and print print 9/1986 from Felix Böttcher GmbH Co ., Cologne, 1984.

Eine Vorrichtung zur Ermittlung der Kontaktposition zweier Walzen zeigt das Schutzrecht DE 42 03 940 A1. Danach werden zwei Walzen solange zueinander zugestellt, bis ein elastisches Element seine elastische Verformung signalisiert. Entsprechende elastische Elemente sind in den Lagerstellen einer der Walzen angeordnet und werden bei einer Bewegung der Lagerzapfen im Rahmen des Lagerspieles beim Aufeinandertreffen der Walzenmäntel verformt. Diese Vorrichtung ist infolge der speziellen konstruktiven Ausführung der Walzenlagerungen aufwendig. Weiterhin ist das funktionell bedingte Lagerspiel nachteilig für die Laufeigenschaften der Walzen.The device right DE 42 03 940 A1 shows a device for determining the contact position of two rollers. Then two rollers are fed towards each other until an elastic element signals its elastic deformation. Corresponding elastic elements are arranged in the bearing points of one of the rollers and are deformed when the bearing journals move as part of the bearing play when the roller shells meet. This device is complex due to the special design of the roller bearings. Furthermore, the functionally related bearing play is disadvantageous for the running properties of the rollers.

Die EP-A-557 198 (Dokument gemäß Artikel 54 (3)EPÜ) stellt ein Verfahren und eine Vorrichtung zur Anzeige der Erreichung der Kontaktposition zweier Walzen vor, bei der die eine Walze auf die zweite rotierende Walze zubewegt wird. Die Friktionsmitnahme, die signalisiert wird, zeigt die Kontaktgabe an. Die Zustellungen werden an beiden Walzenenden separat vorgenommen. Schließlich werden die registrierten Zustellwerte an beiden Seiten eingestellt.EP-A-557 198 (document according to Article 54 (3) EPC) presents a method and a device for indicating the reaching of the contact position of two rollers, in which one roller is moved towards the second rotating roller. The friction carry that is signaled indicates the contact. Infeeds are carried out separately at both roller ends. Finally, the registered delivery values are set on both sides.

Es ist Aufgabe der Erfindung, ein Verfahren zu schaffen, das es ermöglicht, bei geringem zeit- und gerätetechnischem Aufwand zwei Walzen eines Druckwerkes auf Berührung einzustellen.It is an object of the invention to provide a method which makes it possible to set two rollers of a printing unit to be touched with little expenditure in terms of time and equipment.

Diese Aufgabe wird durch die Anwendung des Kennzeichens des einzigen Anspruchs gelöst. Die Erfindung vermeidet zu wiederholende Einstellvorgänge und ermöglicht dadurch eine zeitsparende Einstellung. Weiterhin ist der technische Aufwand gering. Die Erfindung kann weiterhin als Teillösung bei einer automatisierten Walzeneinstellung angewendet werden.This problem is solved by the application of the characteristic of the single claim. The invention avoids repeated adjustment processes and thereby enables time-saving adjustment. Furthermore, the technical effort is low. The invention can also be used as a partial solution in an automated roll setting.

Mehrere Beispiele sind, zum Teil anhand der Zeichnungen, beschrieben, wobei lediglich das zuletzt beschriebene Verfahren Gegenstand der Erfindung ist. In den zugehörigen Zeichnungen zeigt:

Fig. 1:
eine am Walzenspalt angeordnete optische Einrichtung,
Fig. 2:
die Draufsicht auf die optische Einrichtung aus Fig. 1,
Fig. 3:
eine am Walzenspalt angeordnete pneumatische Einrichtung.
Several examples are described, partly with reference to the drawings, only the last-described method being the subject of the invention. In the accompanying drawings:
Fig. 1:
an optical device arranged at the nip,
Fig. 2:
the top view of the optical device of FIG. 1,
Fig. 3:
a pneumatic device arranged at the nip.

In Fig. 1 sind zwei im Abstand zueinander verstellbare Walzen 1, 2 gezeigt, und zwar ist die Walze 1 gegenüber der Walze 2 verstellbar. Die Walze 2 könnte beispielsweise einen Reibzylinder eines Farbwerkes darstellen und die Walze 1 eine Farbauftragwalze, die, nicht dargestellt, außerdem mit einem Formzylinder in Kontakt bringbar ist. Auf einer Seite der Walzen 1, 2 ist in deren Walzenspalt eine aus einem Sender 3 und einem Empfänger 4 bestehende optische Einrichtung 5 angeordnet. Dabei sind der Sender 3 und der Empfänger 4 einander gegenüberliegend beiderseits des Walzenspaltes positioniert. Die optische Einrichtung 5 ist auf einer Grundplatte 6 montiert, die magnetisch ist und so leicht auf die Gestellwand 7 der Druckmaschine gesetzt werden kann. Die optische Einrichtung 5 ist mit einer Anzeigevorrichtung 8 verbunden, wobei vorteilhaft zwecks Miniaturisierung Lichtleiter auf Glasfaserbasis zur Anwendung kommen.1 shows two rollers 1, 2 which are adjustable at a distance from one another, specifically the roller 1 is adjustable relative to the roller 2. The roller 2 could, for example, represent a distribution cylinder of an inking unit and the roller 1 an inking roller, which, not shown, can also be brought into contact with a forme cylinder. An optical device 5 consisting of a transmitter 3 and a receiver 4 is arranged on one side of the rolls 1, 2 in the roll gap thereof. The transmitter 3 and the receiver 4 are positioned opposite each other on both sides of the nip. The optical device 5 is mounted on a base plate 6, which is magnetic and can thus be easily placed on the frame wall 7 of the printing press. The optical device 5 is connected to a display device 8, optical fibers based on glass fibers advantageously being used for the purpose of miniaturization.

Die optische Einrichtung 5 wird zunächst auf einer Seite der Walzen 1, 2 eingeführt. Letztere sind dabei bewußt außer Kontakt gestellt. Der Empfänger 4 erhält vom Sender 3 ausgesandtes Licht. Nun wird auf dieser Seite die Walze 1 zur Walze 2 zugestellt, bis der Empfänger 4 kein Licht mehr erhält, was die Anzeigevorrichtung 8 anzeigt. Die Walzen 1, 2 sind auf dieser Seite somit auf Berührung eingestellt. Die Einstellung erfolgt auf der Gegenseite der Walzen 1, 2 in selber Weise, wobei die optische Einrichtung 5 auf die andere Seite umgesetzt wird.The optical device 5 is first introduced on one side of the rollers 1, 2. The latter are deliberately out of contact. The receiver 4 receives light emitted by the transmitter 3. Now the roller 1 is fed to the roller 2 on this side until the receiver 4 no longer receives any light, which is indicated by the display device 8. The rollers 1, 2 are thus set to touch on this side. The setting is made on the opposite side of the rollers 1, 2 in the same way, the optical device 5 being implemented on the other side.

In Fig. 3 kommt zur Einstellung der Walzen 1, 2 eine pneumatische Einrichtung 9 zur Anwendung. Analog der optischen Einrichtung wird die pneumatische Einrichtung am Walzenspalt im Randbereich der Walzenmäntel beider Walzen 1, 2 angeordnet. Die pneumatische Einrichtung 9 enthält eine Düse 10 und einen Drucksensor. Letzterer ist mit einer Anzeigevorrichtung 11 verbunden.In Fig. 3, a pneumatic device 9 is used to adjust the rollers 1, 2. Analogous to the optical device, the pneumatic device is arranged at the roll gap in the edge region of the roll shells of both rolls 1, 2. The pneumatic device 9 contains a nozzle 10 and a pressure sensor. The latter is connected to a display device 11.

Die Walzen 1, 2 sind zunächst außer Kontakt. Die pneumatische Einrichtung 9 wird mit Druckluft versorgt, die die Düse 10 in den Walzenspalt bläst. Beim Zustellen der Walze 1 zur Walze 2 hin erhöht sich der Staudruck im Walzenspalt, der vom Drucksensor registriert wird. Beim Erreichen eines Maximalwertes zeigt die Anzeigevorrichtung 11 die Berührung beider Walzen 1, 2 an. In gleicher Weise wird anschließend nach Umsetzen der pneumatischen Einrichtung die Einstellung der Walzen 1, 2 auf der anderen Seite vorgenommen. Die pneumatische Einrichtung kann auch mit einem separaten Drucksensor ausgeführt sein, der der Düse 10 gegenüberliegend auf der anderen Seite des Walzenspaltes angeordnet ist. In diesem Fall wird der vom Drucksensor registrierte Druck mit zunehmender Annäherung der Walze 1 an die Walze 2 geringer und ist bei Berührung beider Walzen 1, 2 Null.The rollers 1, 2 are initially out of contact. The pneumatic device 9 is supplied with compressed air, which blows the nozzle 10 into the nip. When the roller 1 is moved towards the roller 2, the dynamic pressure in the roller gap, which is registered by the pressure sensor, increases becomes. When a maximum value is reached, the display device 11 shows the contact of both rollers 1, 2. In the same way, the rollers 1, 2 are then set on the other side after the pneumatic device has been moved. The pneumatic device can also be designed with a separate pressure sensor, which is arranged opposite the nozzle 10 on the other side of the nip. In this case, the pressure registered by the pressure sensor decreases as the roller 1 approaches the roller 2 and is zero when both rollers 1, 2 come into contact.

Nachfolgend sollen zwei Verfahren beschrieben werden, mittels derer die Berührung zweier Walzen zeitsparend und mit geringem Aufwand vorgenommen werden kann. Das eine Verfahren bedient sich dabei des Effektes, daß eine erste angetriebene Walze bei Berührung eine zweite Walze antreibt. Die erste Walze wird hierzu über den Farbwerkhilfsantrieb mit langsamer Drehzahl angetrieben. Die zweite Walze ist zunächst außer Kontakt mit der ersten und wird auf einer Seite soweit zu dieser angestellt bis sie sich zu drehen anfängt. Der Berührungspunkt ist damit gefunden. Die entsprechende Einstellung wird registriert und die Walze sodann wieder außer Kontakt gebracht. Auf gleiche Weise erfolgt nunmehr die Einstellung des Berührungspunktes auf der zweiten Seite. Ist dort die Berührung festgestellt, kann auch die erste Seite wieder auf den registrierten Wert gefahren werden. Die Berührungslinie ist nun eingestellt. Der Beginn der Drehung der Walze kann entweder visuell beobachtet oder über geeignete Hilfsmittel, beispielsweise einen Drehgeber, rückgemeldet werden.Two methods are described below by means of which the contacting of two rollers can be carried out in a time-saving manner and with little effort. One method uses the effect that a first driven roller drives a second roller when touched. For this purpose, the first roller is driven by the auxiliary inking drive at a slow speed. The second roller is initially out of contact with the first and is positioned on one side until it begins to turn. The point of contact has been found. The corresponding setting is registered and the roller is then brought out of contact again. The point of contact is now set in the same way on the second side. If the touch is detected there, the first page can also be moved back to the registered value. The contact line is now set. The start of the rotation of the roller can either be observed visually or reported back using suitable aids, for example a rotary encoder.

Nach dem erfindungsgemäßen Verfahren zur Einstellung der Berührung zweier Walzen wird auf einer Seite der abgestellten Walzen in deren Walzenspalt eine Piezofolie bekannter Dicke eingeführt. Anschließend werden die Walzen auf dieser Seite zueinander verstellt, bis die Piezofolie bei der ersten Berührung mit beiden Walzen ein Ausgangssignal abgibt, was von einer Anzeigevorrichtung signalisiert wird. Die Piezofolie wird nunmehr aus dem Walzenspalt entnommen und auf der anderen Seite der Walze in den Walzenspalt eingeführt. Sodann wird dort der Einstellvorgang wiederholt. Schließlich werden nach Entnahme der Piezofolie aus dem Walzenspalt die Walzen beidseitig um den Betrag der Dicke der Piezofolie zueinander angestellt.According to the method according to the invention for adjusting the contact between two rollers, a piezo film of known thickness is inserted into the roller gap on one side of the rollers that are parked. The rollers on this side are then adjusted relative to one another until the piezo film emits an output signal when it is first touched by both rollers, which is signaled by a display device. The piezo film is now removed from the nip and inserted into the nip on the other side of the roller. Then the setting process is repeated there. Finally, after the piezo film has been removed from the nip, the rolls are set on both sides by the amount of the thickness of the piezo film relative to one another.

Das letztgenannte Verfahren sowie die Vorrichtungen bergen nur eine geringe Unfallgefahr in sich, da bei ihrer Anwendung das Farbwerk nicht drehen muß.The latter method and the devices pose only a small risk of an accident since the inking unit does not have to turn when they are used.

Nicht zum Gegenstand der Erfindung gehört die Art der Anstellung der Walzen, die beispielsweise motorisch erfolgen kann. Auch kann die nach erfolgter Einstellung der Berührung vorzunehmende Anstellung der Walzen mittels eines induktiven Wegaufnehmers oder anderweitigen Stellungsgebers registriert werden. Unter solchen Gegebenheiten kann die Erfindung als Teillösung in automatisierte Walzeneinstellsysteme eingehen.The type of employment of the rollers, which can be done, for example, by a motor, is not part of the invention. The adjustment of the rollers to be carried out after the contact has been set can also be registered by means of an inductive displacement transducer or other position transmitter. Under such circumstances, the invention can be used as a partial solution in automated roll setting systems.

Die Erfindung wurde an Farbwalzen beschrieben. Ebenso können an Hand der Erfindung auch Feuchtwalzen oder andere Walzen eines Druckwerkes auf Berührung eingestellt werden.The invention has been described on ink rollers. Likewise, dampening rollers or other rollers of a printing unit can also be set to touch on the basis of the invention.
