Description

Die Erfindung betrifft eine Bearbeitungsmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a processing machine according to the preamble of claim 1.

Stand der TechnikState of the art

An für den Etikettendruck oder Verpackungsdruck konzipierte oder eingesetzte Druckmaschinen werden zunehmend hohe Anforderungen hinsichtlich der Wirtschaftlichkeit und der Einfachheit der Bedienung bei gleichzeitig maximierter Variabilität für die Produktherstellung gestellt. Beispielsweise soll die Druckmaschine möglichst wenig Makulatur, beispielsweise beim Umrüsten zwischen verschiedenen Druckaufträgen, auch zwischen verschiedenen Druckverfahren oder Drucklängen, verursachen. Geläufige für den Etikettendruck, insbesondere für den Selbstklebeetikettendruck, ausgelegte Schmalbahndruckmaschinen und für den Faltschachteldruck ausgelegte Bahndruckmaschinen in Reihenbauweise weisen meist einen Maschinenaufbau auf, in dem ein Bedruckstoff oder ein Substrat über eine Vielzahl von Zylindern und Walzen zwischen verschiedenen Prozessebenen (beispielsweise für den Druck und für die Trocknung) geführt wird. Eine zwischen verschiedenen Druckverfahren umrüstbare Etikettendruckmaschine ist im Dokument WO 2005/028202 A1 beschrieben. Um zu erreichen, dass die Druckmaschine schnell umgerüstet werden kann, ist beispielsweise die Verwendung von Sleevezylindern bekannt, welche einfach gewechselt werden können.Printing presses designed or used for label printing or packaging printing are becoming increasingly demanding in terms of economy and ease of operation while maximizing variability in product manufacturing. For example, the printing machine should cause as little paper waste as possible, for example when converting between different print jobs, and also between different printing methods or print lengths. Commonly used for label printing, especially for self-adhesive label printing, designed narrow web presses and folding carton printing line printing machines in a row usually have a machine structure in which a substrate or a substrate on a variety of cylinders and rollers between different process levels (for example, for printing and for the drying) is performed. A convertible between different printing process label printing machine is in the document WO 2005/028202 A1 described. To achieve that the printing press can be converted quickly, for example, the use of sleeve cylinders is known, which can be easily changed.

Die DE 699 10 299 T2 zeigt eine Schmalbahn-Druckmaschine mit einer Vielzahl von Flexodruckwerken. Die Druckzylinder sind freigebbar ausgebildet, so dass Drucksleeves einfach gewechselt werden können. Dazu bleiben die Druckzylinder an ihrem antriebsseitigen Ende in einem Lager gehalten, während das bedienseitige Lager geöffnet wird. Aufgrund des hohen Eigengewichts der Druckzylinder senken diese sich auf der Bedienseite ab, sobald das Lager geöffnet ist. Daher kann es beim Wiederverschließen des Lagers zum Arretieren des Druckzylinders auch auf seiner bedienseitigen Antriebsachse zu Schwierigkeiten beim Schließen des Lagers kommen. Weil der Druckzylinder eben nicht in einer exakt waagrechten Position verbleibt, muss beim Schließen des bedienseitigen Lagers, das heißt beim Einfädeln der bedienseitigen Antriebsachse in das Lager, ein Abstand bzw. eine Neigung von wenigen Millimetern überbrückt werden.The DE 699 10 299 T2 shows a narrow web printing machine with a variety of flexographic printing units. The printing cylinders are designed to be releasable, so that printing sleeves can be easily exchanged. For this purpose, the pressure cylinders are held at their drive-side end in a camp, while the service-side bearing is opened. Due to the high weight of the impression cylinders, they lower on the operating side as soon as the bearing is open. Therefore, when resealing the Bearings for locking the printing cylinder also come on its operator-side drive axle to difficulties in closing the camp. Because the printing cylinder just does not remain in an exactly horizontal position, a distance or an inclination of a few millimeters must be bridged when closing the operator-side bearing, that is when threading the operator-side drive axle in the camp.

Zur Lösung dieses Problems schlägt die EP 0 279 394 A2 eine spezielle Lagerung des antriebsseitigen Achsenendes eines Bearbeitungszylinders vor, um eine Absenkbewegung des freien Endes der Achse, das heißt des bedienseitigen Endes der Achse, zu verhindern. Dazu ist eine Haltevorrichtung mit einer einseitigen Abstützeinheit vorgesehen. Die Abstützeinheit besitzt eine Hilfswelle, welche auf dem antriebsseitigen Achszapfen aufsitzt. Diese mechanisch aufwändige Lösung erfordert im Bereich des Antriebsstranges zusätzlichen Bauraum. Da dieser nicht bei allen Maschinentypen vorhanden ist, lässt sich die vorgeschlagene Haltevorrichtung nicht in allen Maschinen anwenden; auch ist eine Nachrüstung von Gebrauchtmaschinen kaum möglich Dokument EP-A-2 221 179 offenbart eine Bearbeitungsmaschine gemäß Oberbegriff von Anspruch 1.To solve this problem proposes the EP 0 279 394 A2 a special support of the drive-side axle end of a machining cylinder in order to prevent a lowering movement of the free end of the axis, that is the operator-side end of the axis. For this purpose, a holding device is provided with a one-sided support unit. The support unit has an auxiliary shaft, which rests on the drive-side axle journal. This mechanically complex solution requires additional space in the area of the drive train. Since this is not available on all machine types, the proposed holding device can not be used in all machines; Also a retrofitting of used machines is hardly possible document EP-A-2 221 179 discloses a processing machine according to the preamble of claim 1.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher, eine Bearbeitungsmaschine mit freigebbarem Bearbeitungszylinder zu schaffen, welche die Nachteile des Standes der Technik nicht aufweist und bei unterschiedlichsten Maschinentypen anwendbar ist.Object of the present invention is therefore to provide a processing machine with releasable processing cylinder, which does not have the disadvantages of the prior art and is applicable to a variety of machine types.

Technische LösungTechnical solution

Gelöst wird diese Aufgabe durch eine Bearbeitungsmaschine mit den Merkmalen von Anspruch 1.This object is achieved by a processing machine having the features of claim 1.

Die erfindungsgemäße Bearbeitungsmaschine, insbesondere eine Druckmaschine, dient der Bearbeitung eines flächenförmigen Substrats, welches ein bahnförmiger oder bogenförmiger Bedruckstoff sein kann. Die Bearbeitungsmaschine besitzt mindestens einen Bearbeitungszylinder, insbesondere einen Sleevezylinder eines Druckwerks zum Bearbeiten des Substrats, wobei das Substrat an dem Bearbeitungszylinder entlang geführt wird. Der Bearbeitungszylinder weist antriebsseitig und bedienseitig jeweils eine Lagervorrichtung auf, wobei zumindest das bedienseitige Lager ein Rotationslager, zum Beispiel ein Nadellager, und eine Lagerschale zur Aufnahme des Rotationslagers aufweist. Erfindungsgemäß ist die Lagerschale an einer verschieblichen Seitenwange als Teil des Maschinengestells angebracht. Die Seitenwange ist entlang mindestens einer, insbesondere horizontalen Führungsschiene verschieblich. Eine Führungsfläche der Seitenwange kann dabei mit einer jeweiligen Führungsschiene zusammen wirken und beide so einen Führungsschlitten bilden. In vorteilhafter Weise ist die Lagerschale relativ zur Seitenwange absenkbar und anhebbar ausgeführt. Das heißt, die Lagerschale kann eine Bewegung nach unten mit zumindest einem vertikalen Anteil ausführen. Ein Freigeben des mindestens einen Bearbeitungszylinders erfolgt durch ein Absenken der Lagerschale und ein Verschieben der Seitenwange. Ein Arretieren des mindestens einen Bearbeitungszylinders erfolgt dann durch Verschieben der Seitenwange und Anheben der Lagerschale. Dank der Absenk- und Anhebbewegung der Lagerschale mit vertikaler Bewegungskomponente wird das aufgrund der Gewichtskraft abgesenkte bedienseitige Ende des Bearbeitungszylinders beim Wiederarretieren von der Lagerschale dort aufgenommen, wo es sich befindet. Es gibt somit keinen störenden Versatz zwischen der Achse des Bearbeitungszylinders und der Lagerschale. Damit wird ein einfaches und schnelles Freigeben des Bearbeitungszylinders bei geringer mechanischer Beanspruchung des Bearbeitungszylinders beim Schließen und Arretieren des bedienseitigen Lagers realisiert.The processing machine according to the invention, in particular a printing press, is used for processing a sheet-like substrate, which may be a web-shaped or sheet-shaped printing material. The processing machine has at least one processing cylinder, in particular a sleeve cylinder of a printing unit for processing the substrate, wherein the substrate is guided along the processing cylinder becomes. The machining cylinder has on the drive side and on the operating side in each case a bearing device, wherein at least the operator-side bearing has a rotary bearing, for example a needle bearing, and a bearing shell for receiving the rotary bearing. According to the invention, the bearing shell is attached to a displaceable side cheek as part of the machine frame. The side wall is displaceable along at least one, in particular horizontal guide rail. A guide surface of the side cheek can act together with a respective guide rail and both form a guide carriage. Advantageously, the bearing shell is designed lowerable and liftable relative to the side cheek. That is, the bearing shell can make a downward movement with at least one vertical component. A release of the at least one machining cylinder is effected by lowering the bearing shell and a displacement of the side cheek. An arresting of the at least one machining cylinder is then carried out by moving the side cheek and lifting the bearing shell. Thanks to the lowering and lifting movement of the bearing shell with vertical movement component, the lowered due to the weight of the operating side end of the machining cylinder is received in the Wiederarretieren of the bearing shell, where it is located. There is thus no disturbing offset between the axis of the machining cylinder and the bearing shell. Thus, a simple and quick release of the processing cylinder is realized at low mechanical stress of the processing cylinder when closing and locking the operator-side bearing.

In vorteilhafter Weiterbildung der erfindungsgemäßen Bearbeitungsmaschine ist ein der Lagerschale zugeordneter Aktuator vorgesehen, welcher insbesondere an der Seitenwange befestigt sein kann zum Bewegen, das heißt Absenken und Anheben der Lagerschale. In vorteilhafter Ausführungsform ist der Aktuator als Pneumatikzylinder ausgeführt. Zusätzlich kann eine Klemmeinheit vorgesehen sein zum Fixieren des Aktuators in einer Arbeitsstellung, derart, dass der Aktuator der Lagerschale unbeweglich wird. Ist der Aktuator der Lagerschale als Pneumatikzylinder ausgeführt, so kann die Klemmeinheit als pneumatische Kolbenklemmung ausgeführt sein.In an advantageous embodiment of the processing machine according to the invention, a bearing shell associated actuator is provided, which may be attached in particular to the side cheek for moving, that is lowering and raising the bearing shell. In an advantageous embodiment, the actuator is designed as a pneumatic cylinder. In addition, a clamping unit may be provided for fixing the actuator in a working position, such that the actuator of the bearing shell is immobile. If the actuator of the bearing shell designed as a pneumatic cylinder, the clamping unit may be designed as a pneumatic piston clamping.

In einer möglichen Ausführungsvariante der erfindungsgemäßen Bearbeitungsmaschine besitzt die Lagerschale eine Anschlagfläche und die Seitenwange besitzt eine komplementäre Anschlagfläche, wobei ein Kontaktieren beider Flächen durch Anheben der Lagerschale erfolgt und so eine definierte Position des Rotationslagers vorgegeben wird.In a possible embodiment of the processing machine according to the invention, the bearing shell has a stop surface and the side cheek has a complementary abutment surface, wherein a contacting of both surfaces takes place by lifting the bearing shell and so a defined position of the rotation bearing is specified.

In einer besonders vorteilhaften und daher bevorzugten Weiterbildung der erfindungsgemäßen Bearbeitungsmaschine ist die Lagerschale an einem Drehpunkt an der Seitenwange aufgenommen, und ist verschwenkbar zur Ausführung der Absenk- und Anhebbewegung. In einer alternativen Ausführungsvariante weist die Seitenwange eine Linearführung auf, in welcher die Lagerschale geführt wird zur Ausführung der Absenk- und Anhebbewegung.In a particularly advantageous and therefore preferred development of the processing machine according to the invention, the bearing shell is received at a pivot point on the side cheek, and is pivotable for carrying out the lowering and raising movement. In an alternative embodiment, the side cheek on a linear guide, in which the bearing shell is guided to perform the lowering and lifting movement.

In Weiterbildung der Bearbeitungsmaschine kann auch der Seitenwange ein Aktuator zugeordnet sein zum Verschieben der Seitenwange. Der Aktuator kann dabei als Spindelantrieb mit Elektromotor ausgeführt sein.In a further development of the processing machine, the side cheek may be associated with an actuator for moving the side cheek. The actuator can be designed as a spindle drive with electric motor.

Um das Freigeben und Arretieren des Bearbeitungszylinders zu automatisieren, so dass hier kein Eingriff des Maschinenbedieners erforderlich ist, ist zum einen eine Maschinensteuerung vorgesehen. Zum anderen sind der Aktuator der Lagerschale, die Klemmeinheit und der Aktuator der Seitenwange datenübertragungstechnisch mit der Maschinensteuerung verbunden und sind von dieser ansteuerbar zum automatischen Freigeben und Arretieren des Bearbeitungszylinders durch Verschieben der Seitenwange und Absenken bzw. Anheben der Lagerschale.In order to automate the release and locking of the processing cylinder, so that no intervention of the machine operator is required here, a machine control is provided on the one hand. On the other hand, the actuator of the bearing shell, the clamping unit and the actuator of the side cheek are data transmission technically connected to the machine control and are actuated by this for automatically releasing and locking the processing cylinder by moving the side cheek and lowering or lifting the bearing shell.

Bei der Bearbeitungsmaschine kann es sich bevorzugt eine Bahndruckmaschine mit einer Mehrzahl von Druckwerken handeln.In the processing machine may preferably be a web printing press with a plurality of printing units.

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.

Zusätzlich bzw. alternativ zu dem Stanzwerk kann auch ein Prägewerk, beispielsweise ein Heißfolienprägewerk Verwendung finden. Alternativ zu den dargestellten Flexodruckwerken können auch Tiefdruck-, Offset-Druckwerke und Rotationssiebdruckwerke eingesetzt werden.In the representation of the individual printing units 110, here flexographic printing units, in addition to the printing cylinders, the impression cylinders and the inking rollers and chamber doctor blade are shown. Furthermore, the printing units 110 in the printing press 100 have various drying devices: The counterpressure cylinders are assigned downstream of the respective printing gap of the printing unit 110 UV drying devices, so that the printed substrate 1000 can be dried directly on the impression cylinder. The printing units 110 also have web guiding rollers 160 for guiding the web-shaped substrate 1000. In the embodiment shown, the fifth printing unit 110 comprises a hot air drying device 162. Alternatively, a UV or an IR drying device could also be used here. Subsequently, a punching unit 150 is arranged, which has a punching cylinder and a counter-punching cylinder as rotating tools. In addition or as an alternative to the stamping plant, it is also possible to use a stamping mill, for example a hot foil stamping mill. As an alternative to the illustrated flexographic printing units, it is also possible to use gravure printing, offset printing units and rotary screen printing units.

In den Figuren 1a und 1b ist ein Druckwerk 110 einer Druckmaschine 100 dargestellt. Zur besseren Erkennbarkeit ist das Substrat 1000, welches in dem Druckwerk 110 bearbeitet wird, nicht dargestellt. Auch ist ausschließlich der eine Bearbeitungszylinder 1 dargestellt, welcher freigegeben werden soll, beispielsweise zum Austausch eines Drucksleeves. Die weiteren Bearbeitungszylinder sowie Transportwalzen des Druckwerks 110 sind ebenfalls nicht dargestellt.In the FIGS. 1a and 1b a printing unit 110 of a printing machine 100 is shown. For better visibility, the substrate 1000, which is processed in the printing unit 110, not shown. Also, only the one processing cylinder 1 is shown, which is to be released, for example, to exchange a Drucksleeves. The other processing cylinders and transport rollers of the printing unit 110 are also not shown.

Der Bearbeitungszylinder 1 wird an seinen beiden Enden, das heißt antriebsseitig sowie bedienseitig, jeweils durch eine Lagervorrichtung 2 aufgenommen und gelagert. Die antriebsseitige Lagervorrichtung 2 ist in den Figuren 1a und 1b nicht zu erkennen. Die bedienseitige Lagervorrichtung 2 weist eine Lagerschale 4 auf, in welcher ein Lager 3, beispielsweise ein als Nadellager ausgeführtes Rotationslager, aufgenommen werden kann.The processing cylinder 1 is at both ends, ie the drive side and the operating side, each received and stored by a bearing device 2. The drive-side bearing device 2 is in the FIGS. 1a and 1b not recognizable. The operator-side storage device 2 has a bearing shell 4, in which a bearing 3, for example, designed as a needle bearing rotary bearing can be added.

In der Darstellung von Figur 1a ist der Bearbeitungszylinder 1 in seiner Arbeitsstellung beidseitig von den Lagervorrichtungen 2 aufgenommen und das Lager 3 ist fest in der Lagerschale 4 arretiert. Die Lagerschale 4, welche um einen Drehpunkt 10 schwenkbar an einer Seitenwange 8 aufgenommen ist, wird in dieser Position von einem Aktuator 11 der Lagerschale 8 gehalten, welcher ausgeführt ist als Pneumatikzylinder. Damit dieser Pneumatikzylinder 11 in seiner Position fixiert bleibt und sich die Lagerschale 4 nicht bewegen kann, ist eine Klemmeinheit 12 vorgesehen, welche auf den Aktuator 11 derart einwirkt, dass der Aktuator in dieser Arbeitsstellung fixiert bleibt. Die Klemmeinheit 12 ist in dem dargestellten Ausführungsbeispiel als pneumatische Kolbenklemmung ausgeführt.In the presentation of FIG. 1a the processing cylinder 1 is received in its working position on both sides of the storage devices 2 and the bearing 3 is fixed in the Bearing shell 4 locked. The bearing shell 4, which is received pivotably about a pivot point 10 on a side wall 8, is held in this position by an actuator 11 of the bearing shell 8, which is designed as a pneumatic cylinder. In order for this pneumatic cylinder 11 remains fixed in position and the bearing shell 4 can not move, a clamping unit 12 is provided, which acts on the actuator 11 such that the actuator remains fixed in this working position. The clamping unit 12 is designed in the illustrated embodiment as a pneumatic piston clamping.

Soll nun der Bearbeitungszylinder 1 auf der Bedienerseite freigegeben werden, so wird die Lagerschale 4 von dem Aktuator 11 um den Drehpunkt 10 geschwenkt, nachdem die Klemmeinheit 12 deaktiviert wurde. Die Lagerschale 4 führt dabei eine Absenkbewegung a aus. In einem zweiten Schritt wird die Seitenwange 8 verschoben entlang von Führungsschienen 5, welche am Maschinengestell 9 angebracht sind. Diese Verschiebebewegung v, welche eine horizontale Bewegung ist, kann durch einen der Seitenwange 8 zugeordneten Aktuator 13 initiiert werden. In der Seitenwange 8 sind Führungsflächen 6 vorgesehen, beispielsweise auch unter Verwendung von Gleitflächen oder Führungsrollen, welche mit den Führungsschienen 5 zusammen wirken und jeweils Führungsschlitten 7 bilden.If now the processing cylinder 1 are released on the operator side, the bearing shell 4 is pivoted by the actuator 11 about the pivot point 10 after the clamping unit 12 has been deactivated. The bearing shell 4 executes a lowering movement a. In a second step, the side wall 8 is displaced along guide rails 5, which are mounted on the machine frame 9. This displacement movement v, which is a horizontal movement, can be initiated by an actuator 13 associated with the side wall 8. In the side cheek 8 guide surfaces 6 are provided, for example, using sliding surfaces or guide rollers which cooperate with the guide rails 5 and each guide carriage 7 form.

Der Aktuator 11 der Lagerschale 4, die Klemmeinheit 12 sowie der Aktuator 13 der Seitenwange 8 sind mit einer Maschinensteuerung 15 über Datenleitungen verbunden und können von dieser angesteuert werden.The actuator 11 of the bearing shell 4, the clamping unit 12 and the actuator 13 of the side wall 8 are connected to a machine control 15 via data lines and can be controlled by this.

Damit sich das Lager 3 in der Arbeitsposition in einer definierten Lage befindet, ist sowohl an der Seitenwange 8 eine Anschlagfläche 15 als auch an der Lagerschale 4 eine Anschlagfläche 16 vorgesehen, welche komplementär zueinander ausgebildet sind und welche sich kontaktieren, wenn die Lagerschale in angehobenem Zustand arretiert ist.Thus, the bearing 3 is in the working position in a defined position, both on the side wall 8, a stop surface 15 and on the bearing shell 4, a stop surface 16 is provided, which are complementary to each other and which contact when the bearing shell in the raised state is locked.
