Description

Die Erfindung betrifft ein Bearbeitungswerk zur rotativen Bearbeitung mit den oberbegrifflichen Merkmalen von Anspruch 1 sowie eine Etikettendruckmaschine mit einem solchen Bearbeitungswerk gemäß Anspruch 7.The invention relates to a machining unit for rotary machining with the preamble features of claim 1 and a label printing machine with such a machining unit according to claim 7.

Stand der TechnikState of the art

Bei Etikettendruckmaschinen, wie sie z.B. in der EP 2 103 429 B1 beschrieben sind kommen Druckwerke und Stanzwerke zum Einsatz. Die Druckwerke umfassen mindestens drei Zylinder, nämlich Farbauftragswalze, Druckzylinder und Gegendruckzylinder. Die rotative Bearbeitung bewirkt hierbei ein Aufbringen von Farbe auf ein Substrat. Die Stanzwerke umfassen mindestens zwei Zylinder, nämlich Stanzzylinder und Stanzgegenzylinder. Die rotative Bearbeitung bewirkt hierbei ein Einbringen von Stanz- und/oder Rilllinien. Zur Anpassung an das zu verarbeitende Substrat sowie ggfs. zur Einstellung der Stanztiefe muss der Spalt, d.h. der Abstand zwischen den Zylindern einstellbar sein.For label printing machines, such as those in the EP 2 103 429 B1 are described printing units and stamping plants are used. The printing units comprise at least three cylinders, namely inking roller, printing cylinder and impression cylinder. The rotary processing causes this application of paint on a substrate. The stamping plants comprise at least two cylinders, namely punching cylinders and punching counter-cylinders. The rotary machining causes this an introduction of punching and / or creasing lines. To adapt to the substrate to be processed and, if necessary, to adjust the punching depth of the gap, ie the distance between the cylinders must be adjustable.

Dazu werden Stützkörper verwendet, welche als Laufringe, Stützringe und als sogenannte Schmitzringe ausgebildet sein können. Beispiele für Einstelleinrichtungen finden sich in der DE 102005015046 A1 und der WO 2012/016758 A1 .For this purpose, supporting bodies are used, which can be designed as races, support rings and as so-called bearer rings. Examples of adjusting devices can be found in the DE 102005015046 A1 and the WO 2012/016758 A1 ,

Die DE 33 17 746 A1 beschreibt eine Etikettendruckmaschine mit den Merkmalen des Oberbegriffs des Anspruchs 1, wobei die jeweiligen Stützkörper als exzentrisch gelagerte Stützringe ausgebildet sind.The DE 33 17 746 A1 describes a label printing machine with the features of the preamble of claim 1, wherein the respective support body are formed as eccentrically mounted support rings.

Nachteilig an derartigen Einstelleinrichtungen ist zum einen deren komplizierter und aufwändiger Aufbau. Zum anderen lässt die Einstellgenauigkeit zu wünschen übrig. Daraus ergibt sich auch eine schlechte Wiederholgenauigkeit. D.h. soll für einen Wiederholauftrag exakt dasselbe Spaltmaß wie bei dessen letzter Ausführung gewählt werden, so gestaltet sich eine derart exakte Einstellung schwierig.A disadvantage of such adjustment is on the one hand their complicated and complex structure. On the other hand, the setting accuracy leaves something to be desired. This also results in a poor repeatability. That should be chosen for a repeat job exactly the same gap as in its last execution, so designed such an exact setting difficult.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher ein Bearbeitungswerk und eine Etikettendruckmaschine mit einem solchen Bearbeitungswerk zu schaffen, bei welcher das Spaltmaß zwischen den Bearbeitungszylindern des Bearbeitungswerks einfach, exakt und wiederholgenau einstellbar ist.Object of the present invention is therefore to provide a processing plant and a label printing machine with such a processing plant, in which the gap between the processing cylinders of the processing plant is simple, accurate and repeatable adjustable.

Technische LösungTechnical solution

Gelöst wird diese Aufgabe durch ein Bearbeitungswerk mit den Merkmalen von Anspruch 1.This problem is solved by a processing plant having the features of claim 1.

Das erfindungsgemäße Bearbeitungswerk, z. B. ein Druckwerk oder Stanzwerk, zur rotativen Bearbeitung eines bahnförmigen oder bogenförmigen Substrats, z.B. zur Herstellung von Etiketten, besitzt mindestens zwei Bearbeitungszylinder und ein Maschinengestell. Dabei ist ein erster Bearbeitungszylinder beweglich im Maschinengestell und ein zweiter Bearbeitungszylinder stationär im Maschinengestell gelagert, wobei jedem Bearbeitungszylinder ein Paar von Stützkörpern zugeordnet ist.The processing unit according to the invention, for. For example, a printing unit or punching unit, for rotative processing of a web-shaped or arcuate substrate, e.g. for the production of labels, has at least two processing cylinders and a machine frame. In this case, a first processing cylinder is movably mounted in the machine frame and a second processing cylinder stationary in the machine frame, wherein each processing cylinder is associated with a pair of supporting bodies.

Erfindungsgemäß weist ein jeweiliger Stützkörper des zweiten Bearbeitungszylinders ein Ringsegment, eine Linearführung, einen gestellfesten Führungskörper und einen Manipulator auf. Der gestellfeste Führungskörper ist am Maschinengestell des Bearbeitungswerkes angebracht. Der Manipulator wirkt auf ein jeweiliges Ringsegment und mittels eines jeweiligen Manipulators kann ein jeweiliges Ringsegment entlang der Linearführung linear verschoben werden. Ein jeweiliges Ringsegment des Stützkörpers des zweiten Bearbeitungszylinders kontaktiert jeweils einen Stützkörper des ersten Bearbeitungszylinders. Das heißt, durch Betätigen des Manipulators kann ein jeweiliges Ringsegment, damit der erste Bearbeitungszylinder mit seinen Stützkörpern verschoben und dadurch der Abstand zwischen den Bearbeitungszylindern angepasst werden.According to the invention, a respective support body of the second machining cylinder has a ring segment, a linear guide, a frame-fixed guide body and a manipulator. The frame-fixed guide body is attached to the machine frame of the processing plant. The manipulator acts on a respective ring segment and by means of a respective manipulator, a respective ring segment along the linear guide can be moved linearly. A respective ring segment of the support body of the second processing cylinder contacts a respective support body of the first processing cylinder. That is, by operating the manipulator, a respective ring segment, so that the first processing cylinder is moved with its supporting bodies and thereby the distance between the processing cylinders to be adjusted.

In einer besonders vorteilhaften und daher bevorzugten Weiterbildung des erfindungsgemäßen Bearbeitungswerks ist der Manipulator als gestellfest gelagerte, drehbare Exzenterrolle oder Spiralrolle ausgebildet. Besonders vorteilhaft ist die Ausbildung als Spiralrolle, nämlich als Kreisevolvente mit konstanter Steigung, da dadurch ein lineares Verstellverhalten erreicht wird:
In vorteilhafter Weise ist die Spiralrolle als verdrehbarer, ring- bzw. scheibenförmiger Körper in Form einer Kreisspirale mit konstanter Steigung ausgeformt. Das heißt, die Spiralrollen haben die Form einer sogenannten arithmetischen bzw. archimedischen Spirale. Die Steigung der Spirale ist abhängig vom zu verstellenden Weg und der gewünschten Verstellauflösung auszuwählen. Die Verwendung derartiger Spiralrollen hat den Vorteil, dass ein lineares, präzises Verstellverhalten des Spaltmaßes ermöglicht wird.
In a particularly advantageous and therefore preferred embodiment of the processing unit according to the invention, the manipulator is designed as a frame-mounted, rotatable eccentric or spiral roller. Particularly advantageous is the Training as a spiral roller, namely as a circle involute with a constant pitch, since this achieves a linear adjustment behavior:
Advantageously, the spiral roll is formed as a rotatable, annular or disc-shaped body in the form of a circular spiral with a constant pitch. That is, the spiral rollers have the form of a so-called arithmetic or Archimedean spiral. The slope of the spiral is to be selected depending on the path to be adjusted and the desired adjustment resolution. The use of such spiral rollers has the advantage that a linear, precise adjustment behavior of the gap dimension is made possible.

In Weiterbildung ist jedem Manipulator ein steuerbarer Elektromotor zugeordnet zum motorischen Rotieren des jeweiligen Manipulators. Alternativ ist jedoch auch eine Verstellung von Hand durch den Maschinenbediener möglich.In a further development, each manipulator is assigned a controllable electric motor for the motorized rotation of the respective manipulator. Alternatively, however, an adjustment by hand by the machine operator is possible.

Besonders vorteilhaft ist es, wenn die Stützkörper des ersten Bearbeitungszylinders als mit dem Bearbeitungszylinder rotierende Laufringe ausgeführt sind. Die Laufringe sind dabei auf der Rotationsachse des Bearbeitungszylinders selbst angeordnet.It when the support body of the first processing cylinder are designed as rotating with the processing cylinder races is particularly advantageous. The races are arranged on the axis of rotation of the machining cylinder itself.

Als besonders vorteilhaft wird es angesehen, wenn der erste Bearbeitungszylinder über einen Verspannmechanismus verfügt zum Anstellen der Bearbeitungszylinder zueinander. Der Verspannungsmechanismus kann dabei als Pneumatikzylinder ausgeführt sein. Auch den weiteren Bearbeitungszylindern kann ein entsprechender Verspannmechanismus zugeordnet sein.It is considered to be particularly advantageous if the first processing cylinder has a bracing mechanism for setting the processing cylinders to one another. The bracing mechanism can be designed as a pneumatic cylinder. Also, the other processing cylinders may be associated with a corresponding Verspannmechanismus.

Die Erfindung betrifft auch eine Etikettendruckmaschine mit mindestens einem wie obenstehend beschriebenen Bearbeitungswerk, wobei insbesondere der erste Bearbeitungszylinder als Druckzylinder, der zweite Bearbeitungszylinder als Gegendruckzylinder und ein weiterer stationärer Bearbeitungszylinder als Farbauftragswalze, insbesondere als Rasterwalze, ausgeführt sind. Die Farbauftragswalze besitzt dann ebenfalls wie oben detailliert beschriebene Stützkörper.
Besitzt das Bearbeitungswerk hingegen nur zwei Bearbeitungszylinder, so kann dieses als Stanzwerk ausgeführt sein, wobei der erste Bearbeitungszylinder als Stanzzylinder und der zweite Bearbeitungszylinder als Gegenstanzzylinder ausgeführt sind. Der gleiche Aufbau eignet sich auch für ein Prägewerk mit Präge- und Gegenprägezylinder.
The invention also relates to a label printing machine with at least one processing unit as described above, wherein in particular the first processing cylinder as a printing cylinder, the second processing cylinder as counter-pressure cylinder and another stationary processing cylinder as an inking roller, in particular as an anilox roller, are executed. The inking roller then also has support bodies as described in detail above.
On the other hand, if the processing plant has only two processing cylinders, then this can be designed as a stamping unit, with the first processing cylinder as the punching cylinder and the second processing cylinder are designed as a counter-punching cylinder. The same structure is also suitable for an embossing mill with embossing and counter embossing cylinder.

Die beschriebene Erfindung und die beschriebenen vorteilhaften Weiterbildungen der Erfindung stellen auch in Kombination miteinander - soweit dies technisch sinnvoll ist - vorteilhafte Weiterbildungen der Erfindung dar.The invention described and the described advantageous developments of the invention are also in combination with each other - as far as is technically feasible - advantageous developments of the invention.

Hinsichtlich weiterer Vorteile und in konstruktiver und funktioneller Hinsicht vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Figuren verwiesen.With regard to further advantages and constructive and functional advantageous embodiments of the invention, reference is made to the dependent claims and the description of exemplary embodiments with reference to the accompanying figures.

Der zweite Zylinder 12 und der dritte Zylinder 13 sind stationär im Maschinengestell 9 gelagert. Der erste Zylinder 11 hingegen ist in einem Lager 15 an einer Schwinge 19 beweglich im Maschinengestell 9 gelagert. Die Rotationsachsen der Zylinder 11, 12, 13 sind mit dem Positionszeichen 16 gekennzeichnet. An der Schwinge 19 ist ein Pneumatikzylinder 14 angebracht, welcher einen Verspannungsmechanismus bildet und dem Anstellen und Anpressen des ersten Zylinders 11 mit einer Kraft F, einer Vorspannkraft, an die beiden stationären Zylinder 12, 13 dient. Axial und beidseitig zum ersten Zylinder 11 sind auf der Drehachse des ersten Zylinders 11 Stützkörper 30 angeordnet, welche als Laufringe ausgeführt sind. Die Laufringe kontaktieren die Stützkörper 20 des zweiten und dritten Zylinders 12,13. Diese Stützkörper 20 sind jeweils entlang einer Linearachse 25 linear verschieblich (vgl. Pfeil v) ausgeführt.In FIG. 1 and 2 is a processing plant 10 shown with a first cylinder 11, with a second cylinder 12 and a third cylinder 13, which are mounted in the machine frame 9. The processing unit 10 is in the illustrated embodiment is a flexographic printing, wherein the first cylinder 11 as a forme cylinder, the second cylinder 12 as a counter-pressure cylinder and the third cylinder 13 anilox roller are designed as. The second cylinder 12 and the third cylinder 13 are stationarily mounted in the machine frame 9. The first cylinder 11, however, is mounted in a bearing 15 on a rocker 19 movable in the machine frame 9. The Rotation axes of the cylinders 11, 12, 13 are marked with the positional mark 16. On the rocker 19, a pneumatic cylinder 14 is mounted, which forms a tensioning mechanism and the hiring and pressing of the first cylinder 11 with a force F, a biasing force to the two stationary cylinders 12, 13 is used. Axially and on both sides of the first cylinder 11 11 support bodies 30 are arranged on the axis of rotation of the first cylinder, which are designed as races. The races contact the support bodies 20 of the second and third cylinders 12, 13. These support bodies 20 are each designed to be linearly displaceable along a linear axis 25 (cf., arrow v).

Während das Bearbeitungswerk 10 gemäß Figur 1 einen ersten Zylinder 11 mit einem größeren Durchmesser aufweist wurde in das Bearbeitungswerk nach Fig. 2 ein erster Zylinder 11' mit einem kleineren Durchmesser montiert. Um die Verwendung von Zylindern 11,11' mit unterschiedlichen Durchmessern zu ermöglichen und auch eine Korrektur des Abstandes zwischen den Zylindern 11, 12, 13 zu ermöglichen ist das Lager 15 des ersten Zylinders 11 mit einem Axial- und Lateralausgleich für eine Korrekturbewegung k versehen (vgl. auch Fig. 3), wobei sich der Ausgleich bei einer Gegenüberstellung der Figuren 1 und 2 ergibt.While the processing unit 10 according to FIG. 1 Having a first cylinder 11 with a larger diameter was after in the processing plant Fig. 2 a first cylinder 11 'with a smaller diameter is mounted.

A pneumatic cylinder 14 associated with the cylinder 11 applies a biasing force F to the cylinder 11, thereby ensuring that its races 30 always rest on the support bodies 20 of the second and third cylinders 12, 13 during operation.

Der Aufbau eines jeweiligen Stützkörpers 20 ist in der Darstellung von Figur 3 im Detail gezeigt.
Die Stützkörper 20 vom zweiten Zylinder 12 und drittem Zylinder 13 haben einen übereinstimmenden Aufbau. Ein jeweiliger Stützkörper 20 besitzt ein Ringelement 23, welches mit einer Linearführung 21 verbunden ist. Die Linearführung 21 wird in einem gestellfesten Führungskörper 22 geführt. Ein drehbarer Manipulator 24 (vgl. Doppelpfeil d) wirkt bei Betätigung auf die Linearführung 21 ein, bewirkt eine Verschiebebewegung v der Linearführung 21 und damit eine Verschiebebewegung v des Ringelements 23. Zum Aufbringen einer Spannkraft S ist - wie oben bereits ausgeführt - ein Pneumatikzylinder 14 vorgesehen, welcher auf die Linearführung 21 einwirkt.
The structure of a respective support body 20 is in the illustration of FIG. 3 shown in detail.
The support body 20 of the second cylinder 12 and third cylinder 13 have a matching structure. A respective support body 20 has a ring element 23, which is connected to a linear guide 21. The linear guide 21 is in a frame-fixed guide body 22 out. A rotatable manipulator 24 (see double arrow d) acts on the linear guide 21 when actuated, causing a displacement movement v of the linear guide 21 and thus a displacement movement v of the ring element 23. To apply a clamping force S is - as already stated above - a pneumatic cylinder fourteenth provided, which acts on the linear guide 21.

Das Ringelement 23, welches an der Linearführung 21 befestigt ist, kann auch als Schmitzringsegment bezeichnet werden. Der Führungskörper 22 kann als an der Druckwerkswand 9 befestigter Führungsklotz ausgeführt sein. Der Manipulator 24 kann als Spirale mit einer Kreisevolvente mit konstanter Steigung ausgeführt sein.The ring element 23, which is fastened to the linear guide 21, can also be referred to as a bearer ring segment. The guide body 22 may be designed as attached to the printing unit wall 9 guide block. The manipulator 24 can be designed as a spiral with a circle involute with a constant pitch.

Eine Korrektur des Abstandes zwischen erstem Zylinder 11 und zweitem Zylinder 12 bzw. zwischen erstem Zylinder 11 und dem drittem Zylinder 13, das heißt eine Anpassung des sogenannten Spaltmaßes zwischen den Zylinder 11,12,13, erfolgt durch eine gezielte Verschiebebewegung v des Ringelements 23 eines jeweiligen Stützkörpers 20.A correction of the distance between the first cylinder 11 and the second cylinder 12 and between the first cylinder 11 and the third cylinder 13, that is, an adaptation of the so-called gap between the cylinder 11,12,13, carried out by a targeted displacement movement v of the ring member 23 a respective support body 20th

In Figur 4 ist eine alternative Ausführung des Bearbeitungswerks 10 aus Figur 3 dargestellt. Dabei verfügt jeder Manipulator 24 über einen steuerbaren Elektromotor 17. Der jeweilige steuerbare Elektromotor 17 bewirkt dann eine Drehbewegung d des Spiral- bzw. Exzenterkörpers. Die Motoren 17 sowie die Pneumatikzylinder 14 sind datenübertragungstechnisch mit einer Steuereinrichtung 18 verbunden, so dass zumindest eine Ansteuerung der Motoren 17 und der Pneumatikzylinder 14 von einem zentralen Bedieninterface der Steuereinrichtung 18 ermöglicht wird.In FIG. 4 is an alternative embodiment of the processing unit 10 off FIG. 3 shown. In this case, each manipulator 24 has a controllable electric motor 17. The respective controllable electric motor 17 then causes a rotational movement d of the spiral or eccentric body. The motors 17 and the pneumatic cylinders 14 are data transmission technology connected to a control device 18, so that at least one control of the motors 17 and the pneumatic cylinder 14 is made possible by a central user interface of the control device 18.
