Stand der TechnikState of the art

Bei Druckmaschinen zum Bedrucken von Etiketten und Faltschachteln ist in zunehmendem Maße eine große Flexibilität oder Variabilität gewünscht, um möglichst viele verschiedenartige Druckaufträge, insbesondere unter Erzeugung von speziellen optischen Effekten durch das gedruckte Bild oder den gedruckten Text, durchführen zu können. Zur Herstellung von Etiketten und Faltschachteln werden besonders häufig Druckmaschinen verwendet, die eine schmale Bahn eines Bedruckstoffs bearbeiten und eine Anzahl von Verbindungsplattformen oder Schnittstellen aufweisen, an denen jeweils eine Funktionseinheit oder ein Verfahrensmodul zum Drucken mit einem bestimmten Druckverfahren lösbar aufgenommen werden kann. Beispielsweise ist eine Ausführungsform einer derartigen Druckmaschine im Dokument US 4,384,522 beschrieben. Die einzelnen Funktionseinheiten können dabei mit voneinander verschiedenen Druckverfahren arbeiten.In printing machines for printing labels and cartons, great flexibility or variability is increasingly desired in order to be able to carry out as many different types of printing jobs as possible, in particular by producing special optical effects through the printed image or the printed text. For the production of labels and folding cartons, printing machines are used which process a narrow web of a printing material and have a number of connection platforms or interfaces, on each of which a functional unit or a process module can be detachably received for printing with a specific printing method. For example, one embodiment of such a printing press is in the document US 4,384,522 described. The individual functional units can work with mutually different printing methods.

Aus den Dokumenten DE 195 13 536 A1 und WO 95/29813 sind Druckmaschinen mit mehreren Druckwerken in Reihenbauweise bekannt, welche die lösbare Aufnahme einer Anzahl von Funktionseinheiten oder Verfahrensmodulen an einer Anzahl von Verbindungsplattformen gestatten. Die Funktionseinheiten können unter anderem Druckwerke oder Teile von Druckwerken in Kassetten oder Aufsätzen enthalten, die nach einem Buchdruckverfahren, einem Flexodruckverfahren, einem Siebdruckverfahren, einem Offsetdruckverfahren, einem Tiefdruckverfahren oder einem Tintenstrahldruckverfahren arbeiten. Darüber hinaus sind Funktionseinheiten (Bearbeitungswerke) vorgesehen, die mechanische Verarbeitungsschritte am Bedruckstoff gestatten, beispielsweise eine Prägung, einen Beschnitt (Perforation, Lochen) oder eine Wendung durchführen. Derartige Druckmaschinen, die mit einer Mehrzahl von unterschiedlichen Druckverfahren arbeiten können, werden auch als Kombinationsdruckmaschinen oder Hybriddruckmaschinen bezeichnet.From the documents DE 195 13 536 A1 and WO 95/29813 Multi-printing presses are known in series construction which permit the detachable receipt of a number of functional units or process modules on a number of interconnect platforms. The functional units may contain, among other things, printing units or parts of printing units in cassettes or essays which operate according to a letterpress method, a flexographic printing method, a screen printing method, an offset printing method, a gravure printing method or an inkjet printing method.

Die DE 103 43 411 B4 zeigt eine Rotationsdruckmaschine mit einem Flexodruckwerk. Auf dem Formzylinder derartiger Flexodruckwerke werden üblicherweise Druckformen, sogenannte Klischees, aufgebracht. Während dem Abrollen des Formzylinders auf den benachbarten Zylindern verursachen die Kanten des Klischees einen sogenannten Gapschlag, auch als Kanalschlag bezeichnet, wobei die Pressung zwischen dem Formzylinder und dem benachbarten Zylinder schlagartig abfällt bzw. ansteigt. Dieser Gapschlag kann dabei zu im Druckbild sichtbaren Störungen führen. Ein Flexodruckwerk nach dem Oberbegriff des Anspruchs 1 ist aus der US 6 422 143 B1 bekannt, die darüber hinaus auch die Vorspannung des Formzylinders über einen Pneumatikzylinder lehrt.The DE 103 43 411 B4 shows a rotary printing machine with a flexographic printing unit. On the form cylinder of such flexographic printing usually printing plates, so-called clichés are applied. During the unwinding of the forme cylinder on the adjacent cylinders, the edges of the plate cause a so-called gap blow, also referred to as a channel blow, wherein the pressure between the forme cylinder and the adjacent cylinder abruptly drops or increases. This gap can lead to visible disturbances in the print image. A flexographic printing according to the preamble of claim 1 is known from US Pat. No. 6,422,143 B1 known, which also teaches the bias of the forme cylinder via a pneumatic cylinder.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es, ein Druckwerk zu schaffen, bei dem der Gapschlag und dessen Auswirkungen reduziert werden, bei dem Formzylinder unterschiedlicher Durchmesser eingesetzt werden können und bei dem Formzylinder einfach ausgetauscht werden können.Object of the present invention is to provide a printing unit in which the Gapschlag and its effects are reduced, can be used in the form of cylinders of different diameters and can be easily replaced in the form of cylinder.

Gelöst wird diese Aufgabe durch ein Druckwerk mit den Merkmalen von Anspruch 1: Das erfindungsgemäße Druckwerk, welches als Flexodruckwerk ausgeführt ist, besitzt eine Rasterwalze, einen Formzylinder und einen Gegendruckzylinder, wobei die Rasterwalze den Formzylinder kontaktiert und zwischen Formzylinder und Gegendruckzylinder ein Druckspalt gebildet wird, und ein Bedruckstoff geführt wird. Das Druckwerk ist geeignet für die Verwendung von Formzylindern von unterschiedlichem Durchmesser. Erfindungsgemäß sind die Rotationsachsen von Rasterwalze und Formzylinder unabhängig vom Durchmesser des Formzylinders in einer horizontalen Ebene und die Rotationsachsen von Formzylinder und Gegendruckzylinder in einer vertikalen Ebene angeordnet, so dass jeweils diametrale Berührpunkte zwischen den Zylindern vorliegen. Durch Gapschlag eingebrachte Schwingungen werden bei dieser erfindungsgemäßen Anordnung der Zylinder im Gegensatz zu aus dem Stand der Technik bekannten Anordnungen nur begrenzt übertragen und Relativbewegungen zwischen den Zylindern werden in vorteilhafter Weise auf ein Minimum beschränkt. Das erfindungsgemäße Druckwerk weist mindestens ein Kniehebelsystem auf zum Aufbringen einer Vorspannkraft auf den Formzylinder. Bevorzugterweise sind jedoch zwei Kniehebelsysteme vorgesehen, jeweils ein Kniehebelsystem für die Antriebsseite und ein Kniehebelsystem für die Bedienerseite des Druckwerks. Der Einsatz mindestens eines Kniehebelsystems zum Aufbringen der Vorspannkraft hat eine Vielzahl von Vorteilen: ein sicheres Halten einer eingestellten Position der Kniehebel des Kniehebelsystems ist möglich; Kniehebel können große Schließkräfte erzeugen; Kniehebel können von außen einwirkende Kräfte wie beispielsweise durch Gapschlag, sehr gut absorbieren; Kniehebel lassen sich sehr exakt ansteuern und regulieren; Kniehebel haben kurze Schließzyklen; Kniehebel lassen sich kostengünstig und kompakt bauen und damit einfach in das Druckwerk integrieren; Kniehebel sind sehr gut für die Linearbewegungen geeignet und ermöglichen damit eine gute Anpassung des Kniehebelsystems an Formzylindern unterschiedlicher Durchmesser.This object is achieved by a printing unit having the features of claim 1: The printing unit according to the invention, which is designed as a flexographic printing unit, has an anilox roller, a forme cylinder and an impression cylinder, wherein the anilox roller contacts the forme cylinder and a pressure gap is formed between the forme cylinder and impression cylinder, and a printing material is guided. The printing unit is suitable for use with cylinders of different diameters. According to the invention, the axes of rotation of the anilox roller and the forme cylinder are arranged independently of the diameter of the forme cylinder in a horizontal plane and the axes of rotation of the forme cylinder and impression cylinder in a vertical plane, so that diametrical contact points exist between the cylinders. By Gapschlag introduced vibrations are in this inventive arrangement of the cylinder in contrast to the prior art known arrangements only limited transfer and relative movements between the cylinders are advantageously limited to a minimum. The printing unit according to the invention has at least one toggle lever system for applying a biasing force to the forme cylinder. Preferably, however, two toggle systems are provided, each a toggle system for the drive side and a toggle lever system for the operator side of the printing unit. The use of at least one toggle lever system for applying the biasing force has a number of advantages: a secure holding a set position of the toggle lever of the toggle lever system is possible; Toggle levers can generate large closing forces; Knee levers can very well absorb external forces such as gap blow; Toggle levers can be controlled and regulated very precisely; Toggle levers have short closing cycles; Toggle levers can be constructed cost-effectively and compactly, making them easy to integrate into the printing unit; Toggle levers are very well suited for the linear movements and thus allow a good adaptation of the toggle lever system to cylinders with different diameters.

In einer vorteilhaften Weiterbildung ist einem jeweiligen Ende der Rasterwalze und einem jeweiligen Ende des Formzylinders je ein Lager zugeordnet, wobei jeweils antriebsseitige und bedienseitige Lager von Rasterwalze und Formzylinder in einer gemeinsamen Lagerplatte angeordnet sind. Die gemeinsame Lagerung von Rasterwalze und Formzylinder in einer Lagerplatte ermöglicht eine Abkopplung der durch Gapschlag entstehenden Impulse.In an advantageous development of a respective end of the anilox roller and a respective end of the forme cylinder is associated with a respective bearing, wherein each drive-side and operation side bearings of anilox roller and form cylinder are arranged in a common bearing plate. The common storage of anilox roller and forme cylinder in a bearing plate allows a decoupling of the pulses generated by Gapschlag.

In einer Weiterbildung weist das Druckwerk mindestens einen Stellantrieb auf, welcher den beiden Lagerplatten zugeordnet ist, zur Höhenanpassung der Lagerplatten in Abhängigkeit vom Durchmesser des Formzylinders. In anderen Worten: die Lager von Formzylinder und Rasterwalze können durch den mindestens einen Stellantrieb gemeinsam soweit angehoben werden, dass ein Druckspalt zwischen Formzylinder und Gegendruckzylinder vorliegt. Die obenstehend erwähnte rechtwinklige Ausrichtung der Zylinder zueinander ändert sich dabei nicht. Der bedingt durch die erfindungsgemäße Zylinderanordnung vorteilhaft gestaltete Kraftfluss bei einem Gapschlag ist somit unabhängig vom Durchmesser des Formzylinders.In a further development, the printing unit has at least one actuator, which is assigned to the two bearing plates, for height adjustment of the bearing plates as a function of the diameter of the forme cylinder. In other words, the bearings of the forme cylinder and anilox roller can be jointly raised by the at least one actuator so far that there is a pressure gap between the forme cylinder and the impression cylinder. The above-mentioned rectangular orientation of the cylinder to each other does not change. The conditional by the invention Cylinder arrangement advantageously designed force flow at a Gapschlag is thus independent of the diameter of the forme cylinder.

In Weiterbildung des erfindungsgemäßen Druckwerks weist ein jeweiliges Kniehebelsystem zwei Hebel auf, wobei ein jeweiliger Hebel an seinem einen Ende mit dem Lager des Formzylinders und an seinem anderen Ende mit einem Aktuator verbunden ist. Vom Aktuator wird somit über die Kniehebel eine Vorspannung auf das Lager des Formzylinders aufgebracht.In a further development of the printing unit according to the invention, a respective toggle lever system has two levers, wherein a respective lever is connected at its one end to the bearing of the forme cylinder and at its other end to an actuator. From the actuator is thus applied via the toggle a bias on the bearing of the forme cylinder.

In einer möglichen Ausführungsvariante betätigt ein jeweiliger Aktuator des Kniehebelsystems beide Hebel des jeweiligen Kniehebelsystems.In a possible embodiment variant, a respective actuator of the toggle lever system actuates both levers of the respective toggle lever system.

Für die Ausführung des Aktuators des Kniehebelsystems sind verschiedenen Varianten denkbar: als Pneumatikzylinder, Hydraulikzylinder, Linearmotor, Doppelhubzylinder, etc.For the execution of the actuator of the toggle lever system, various variants are conceivable: as a pneumatic cylinder, hydraulic cylinder, linear motor, Doppelhubzylinder, etc.

In einer vorteilhaften Weiterbildung des erfindungsgemäßen Druckwerks sind in den Lagern des Formzylinders, genauer: in den Lagerschalen, Messelemente vorgesehen, insbesondere Dehnungsmessstreifen, zur Druckkraftmessung. Durch die Anordnung der Messelemente sowohl im antriebsseitigen als auch im bedienerseitigen Lager des Formzylinders kann die Druckkraft in beiden Lagern unabhängig bestimmt werden. Vorteilhafterweise ist dem Druckwerk eine Auswerte- und Steuereinheit zugeordnet, wobei diese über Datenleitungen mit den Messelementen, dem mindestens einen Aktuator und eventuell dem mindestens einen Stellantrieb verbunden ist. Die Auswerte- und Steuereinheit dient zumindest der Auswertung der Messergebnisse der Messelemente und der Ansteuerung der Aktuatoren. In der Auswerte- und Steuereinheit kann eine Wertetabelle hinterlegt sein, welche ein sogenanntes Selbstteaching der Druckkrafteinstellung ermöglicht, d. h. eine automatische Einstellung der Druckkraft. Dazu kann in der Wertetabelle eine Solldruckkraft hinterlegt sein, welche abhängig von Druckplatte, Tape, Klischee, Substrat, etc. vorgegeben wird.In an advantageous development of the printing unit according to the invention, measuring elements are provided in the bearings of the forme cylinder, more precisely: in the bearing shells, in particular strain gauges, for pressure force measurement. Due to the arrangement of the measuring elements both in the drive-side and in the operator-side bearing of the forme cylinder, the pressure force in both bearings can be determined independently. Advantageously, the printing unit is associated with an evaluation and control unit, which is connected via data lines with the measuring elements, the at least one actuator and possibly the at least one actuator. The evaluation and control unit serves at least the evaluation of the measurement results of the measuring elements and the actuation of the actuators. In the evaluation and control unit, a value table can be stored, which allows a so-called Selbstteaching the pressure force adjustment, d. H. an automatic adjustment of the pressure force. For this purpose, a desired pressure force can be stored in the value table, which depends on the printing plate, tape, cliché, substrate, etc. is specified.

Die Erfindung betrifft auch eine Schmalbahn-Etikettendruckmaschine mit mindestens einem wie obenstehend beschriebenen Druckwerk.The invention also relates to a narrow web label printing machine having at least one printing unit as described above.

Fig. 1a zeigt ein erfindungsgemäßes Druckwerk 10, welches als Flexodruckwerk ausgeführt ist. Das Druckwerk 10 besitzt einen Formzylinder 2, eine Rasterwalze 1 und einen Gegendruckzylinder 3. An die Rasterwalze 1 ist eine Rakel 5 angestellt. Die Rasterwalze 1 als auch der Formzylinder 2 besitzen Lager 6.1, welche in einer gemeinsamen Lagerplatte 6.2 angeordnet sind. An dem Lager 6.1 des Formzylinders 2 wird ein Kniehebelsystem 4.1 angebracht, welches eine Vorspannkraft F auf das Lager 6.1 und damit auf den Formzylinder 2 aufbringt. Der Lagerplatte 6.2 ist ein Stellantrieb 7 zugeordnet, wobei die Bewegung des Stellantriebs 7 über eine Spindelwelle 9 auf die Lagerplatte 6.2 übertragen wird. Dadurch wird es ermöglicht, die Position der Lagerplatte 6.2 in vertikaler Richtung im Sinne einer Hubbewegung h zu verschieben und somit die Position des Lagers 6.1 des Formzylinders 2 abhängig vom Durchmesser des Formzylinders 2 anzupassen. Während in Fig. 1a ein Formzylinder 2 größeren Durchmessers dargestellt ist, zeigt die Fig. 1b einen Formzylinder 2 kleineren Durchmessers. Um zwischen Formzylinder 2 und Gegendruckzylinder 3 weiterhin einen Druckspalt zu bilden, wurde die Lagerplatte 6.2 im Sinne einer vertikalen Verschiebebewegung h von dem Stellantrieb 7 abgesenkt. Auch das Kniehebelsystem 4.1 wurde durch Verschiebebewegungen v angepasst, so dass das Kniehebelsystem 4.1 weiterhin auf das Lager 6.1 des Formzylinders 2 wirkt und eine Vorspannkraft F aufbringt. Fig. 1a shows an inventive printing unit 10, which is designed as a flexographic printing unit. The printing unit 10 has a form cylinder 2, an anilox roller 1 and a counter-pressure cylinder 3. To the anilox roller 1, a doctor blade 5 is employed. The anilox roller 1 and the forme cylinder 2 have bearings 6.1, which are arranged in a common bearing plate 6.2. At the bearing 6.1 of the forme cylinder 2, a toggle lever system 4.1 is attached, which applies a biasing force F on the bearing 6.1 and thus on the forme cylinder 2. The bearing plate 6.2 is associated with an actuator 7, wherein the movement of the actuator 7 is transmitted via a spindle shaft 9 on the bearing plate 6.2. This makes it possible to move the position of the bearing plate 6.2 in the vertical direction in the sense of a lifting movement h and thus adapt the position of the bearing 6.1 of the forme cylinder 2 depending on the diameter of the forme cylinder 2. While in Fig. 1a a form cylinder 2 of larger diameter is shown, which shows the Fig. 1b a form cylinder 2 of smaller diameter. In order to continue to form a pressure nip between the forme cylinder 2 and counter-pressure cylinder 3, the bearing plate 6.2 has been lowered by the actuator 7 in the sense of a vertical displacement movement h. The toggle lever system 4.1 has been adapted by displacement movements v, so that the toggle lever system 4.1 continues to act on the bearing 6.1 of the forme cylinder 2 and a biasing force F applies.

Unabhängig vom Durchmesser des Formzylinders 2 bleibt die vorteilhafte Zylinderanordnung (vgl. Fig. 3b) erhalten: Rasterwalze 1 und Formzylinder 2 liegen in einer horizontalen Ebene HE, Formzylinder 2 und Gegendruckzylinder 3 in einer vertikalen Ebene VE.Regardless of the diameter of the forme cylinder 2, the advantageous cylinder arrangement (see FIG. Fig. 3b Anilox roller 1 and forme cylinder 2 lie in a horizontal plane HE, forme cylinder 2 and impression cylinder 3 in a vertical plane VE.

In Fig. 2 ist der Aufbau des Kniehebelsystems 4.1 näher dargestellt: das Kniehebelsystem 4.1 besitzt zwei Kniehebel 4.2, welche an ihrem einen Ende mit dem Lager 6.1 des Formzylinders 2 verbunden sind. An dem jeweils anderen Ende ist der Kniehebel 4.2 in einer Führung 4.4 geführt. Wie sich aus den Figuren 4a und 4b ergibt, ist dieses Ende des Kniehebels 4.2 zusätzlich mit einem Aktuator 4.3 verbunden. Dabei kann entweder, wie in Fig. 4a dargestellt, ein Aktuator 4.3 eingesetzt werden, welcher auf beide Kniehebel 4.2 wirkt, oder es kann, wie in Fig. 4b dargestellt, jedem Kniehebel 4.2 ein Aktuator 4.3 zugeordnet sein. In der Darstellung von Fig. 2 wurde das Lager 6.1 des Formzylinders 2 von den Kniehebeln 4.2 so weit angehoben, dass der Formzylinder 2 aus dem Druckwerk 10 entfernt werden kann und somit ein Umrüsten des Druckwerks 10 ermöglicht wird.In Fig. 2 the construction of the toggle lever system 4.1 is shown in more detail: the toggle lever system 4.1 has two toggle levers 4.2, which are connected at one end to the bearing 6.1 of the forme cylinder 2. At the other end of the knee lever 4.2 is guided in a guide 4.4. As is clear from the FIGS. 4a and 4b results, this end of the bell crank 4.2 is additionally connected to an actuator 4.3. It can either, as in Fig. 4a shown, an actuator 4.3 are used, which acts on both toggle 4.2, or it can, as in Fig. 4b represented, each knee lever 4.2 an actuator 4.3 be assigned. In the presentation of Fig. 2 was the bearing 6.1 of the forme cylinder 2 lifted by the knee levers 4.2 so far that the forme cylinder 2 can be removed from the printing unit 10 and thus a retooling of the printing unit 10 is made possible.

In Fig. 3a ist die Anordnung der Zylinder 1, 2, 3 des Druckwerks 10 dargestellt. Zur besseren Übersichtlichkeit wurde das Kniehebelsystem 4.1 weggelassen. Von der Rasterwalze 1, welche nur leicht im Hintergrund zu erkennen ist, wird Farbe auf ein auf dem Formzylinder 2 aufgebrachtes Klischee 2.1 übertragen. Im Druckspalt zwischen Formzylinder 2 und Gegendruckzylinder 3 wird eine Bedruckstoffbahn 100 geführt, auf welche durch das Klischee 2.1 ein Druckbild 101 aufgebracht wird. In den Lagern 6.1 des Formzylinders 2 sind Messelemente 6.3 angeordnet, welche beispielsweise als Dehnungsmessstreifen ausgeführt sein können. Die Messelemente 6.3 sind mit einer Auswerte- und Steuereinheit 8 verbunden. Mit dieser Auswerte- und Steuereinheit 8 sind ebenfalls die Aktuatoren 4.3 des Kniehebelsystems 4.1 und gegebenenfalls der Stellantrieb 7 verbunden und können von der Auswerte- und Steuereinheit 8 angesteuert werden.In Fig. 3a the arrangement of the cylinders 1, 2, 3 of the printing unit 10 is shown. For clarity, the toggle system 4.1 has been omitted. From the anilox roller 1, which can be seen only slightly in the background, color is transferred to an applied on the forme cylinder 2 cliche 2.1. In the nip between the forme cylinder 2 and counter-pressure cylinder 3, a printing material web 100 is guided, on which a printing image 101 is applied by the printing plate 2.1. In the bearings 6.1 of the forme cylinder 2, measuring elements 6.3 are arranged, which may for example be designed as strain gauges. The measuring elements 6.3 are connected to an evaluation and control unit 8. With this evaluation and control unit 8, the actuators 4.3 of the toggle lever system 4.1 and optionally the actuator 7 are also connected and can be controlled by the evaluation and control unit 8.

Aus der Ansicht in Fig. 3b ergibt sich die erfindungsgemäße Anordnung der Zylinder 1, 2, 3. Die Rasterwalze 1 und der Formzylinder 2 sind so angeordnet, dass sich ihre Rotationsachsen in einer horizontalen Ebene HE befinden. Der Formzylinder 2 und der Gegendruckzylinder 3 sind so angeordnet, dass sich ihre Rotationsachsen in einer vertikalen Ebene VE befinden. Durch diese Anordnung ergibt sich, dass es zwischen Rasterwalze 1 und Formzylinder 2 einen diametralen Berührpunkt B und zwischen Formzylinder 2 und Gegendruckzylinder 3 ebenfalls einen diametralen Berührpunkt B gibt.From the view in Fig. 3b The inventive arrangement of the cylinder 1, 2, 3. The anilox roller 1 and the forme cylinder 2 are arranged so that their axes of rotation are in a horizontal plane HE. The forme cylinder 2 and the impression cylinder 3 are arranged so that their axes of rotation are in a vertical plane VE. As a result of this arrangement, there is a diametrical contact point B between the anilox roller 1 and the forme cylinder 2 and also a diametrical contact point B between the forme cylinder 2 and impression cylinder 3.
