Description

Die Erfindung betrifft ein Farbwerk einer Druckmaschine nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Befestigen wenigstens eines Farbwerkszylinders an einem Schlitten eines Farbwerks nach dem Oberbegriff des Anspruchs 7.The invention relates to an inking unit of a printing press according to the preamble of claim 1 and a method for fastening at least one inking unit cylinder to a carriage of an inking unit according to the preamble of claim 7.

Zur Abwicklung von Druckaufträgen ist es häufig notwendig, Teile von Farbwerkszylindern, insbesondere deren Funktionselement, in der Regel eine äußere Hülse, zu wechseln. Daher ist es bekannt, einen Farbwerkzylinder während des Druckbetriebs beidendig in jeweils einem Tragelement rotierbar zu lagern, zum Wechseln des Funktionselements allerdings auf einer Seite ein Lagergehäuse vorzusehen, welchem ein Lager zugeordnet ist, in welchem ein Zapfen des Farbwerkzylinders rotierbar gelagert ist, wobei das Lagergehäuse relativ zum Tragelement um wenigstens eine Schwenkachse schwenkbar ist, um den Zapfen des Farbwerkszylinders freizulegen oder zu lagern. Zusätzlich ist eine Arretiervorrichtung vorgesehen, mit welcher das Lagergehäuse an dem Tragelement verbunden ist.To process print jobs, it is often necessary to change parts of the inking unit cylinders, in particular their functional element, usually an outer sleeve. It is therefore known to mount an inking cylinder rotatably at both ends in a support element during printing operation, but to change the functional element, however, to provide a bearing housing on one side to which a bearing is assigned, in which a journal of the inking cylinder is rotatably mounted, the bearing housing is pivotable relative to the support element about at least one pivot axis in order to expose or support the journal of the inking cylinder. In addition, a locking device is provided with which the bearing housing is connected to the support element.

Die Anmeldung EP 2 079 588 A1 zeigt ein solches Farbwerk. Nachteilig bei einem solchen Farbwerk ist es allerdings, dass die Arretierung manuell erfolgt, so dass die mechanische Stabilität vom Maschinenbediener abhängt. Qualitativ minderwertige Drucke können die Folge sein.The registration EP 2 079 588 A1 shows such an inking unit. A disadvantage of such an inking unit, however, is that it is locked manually, so that the mechanical stability depends on the machine operator. Inferior prints can result.

Die Aufgabe der vorliegenden Erfindung ist es daher, ein Farbwerk und ein Verfahren vorzuschlagen, mit welchen reproduzierbar qualitativ bessere Drucke als im Stand der Technik möglich sind.The object of the present invention is therefore to propose an inking unit and a method with which reproducibly higher quality prints than in the prior art are possible.

Erfindungsgemäß wird diese Aufgabe durch sämtliche Merkmale des Anspruchs 1 gelöst. In den abhängigen Ansprüchen sind mögliche Ausgestaltungen der Erfindung angegeben.According to the invention, this object is achieved by all the features of claim 1. Possible configurations of the invention are specified in the dependent claims.

Gemäß der vorliegenden Erfindung ist vorgesehen, dass die Arretiervorrichtung wenigstens zwei gelenkig miteinander verbundene Hebelelemente umfasst, wobei ein erstes Hebelelement in dem Tragelement gelagert und relativ zu diesem bewegbar ist, insbesondere linear bewegbar ist, und ein zweites Hebelelement schwenkbar an dem Lagergehäuse gelagert ist, wobei die Arretiervorrichtung einen Anschlag für das Lagergehäuse und/oder das zweite Hebelelement umfasst, wobei die Hebelelemente derart bewegbar und miteinander verbunden sind, dass das Lagergehäuse und/oder der zweite Hebelarm mit einer Andrückkraft gegen den Anschlag andrückbar ist.According to the present invention, it is provided that the locking device comprises at least two lever elements which are connected to one another in an articulated manner, a first lever element being mounted in the support element and being movable relative thereto, in particular being linearly movable, and a second lever element being pivotably mounted on the bearing housing, wherein the locking device comprises a stop for the bearing housing and / or the second lever element, the lever elements being movable and connected to one another in such a way that the bearing housing and / or the second lever arm can be pressed against the stop with a pressing force.

Durch ein erstes Hebelelement ist also ein zweites Hebelelement bewegbar, wobei das zweite Hebelelement schwenkbar an dem Lagergehäuse angeordnet ist. Durch die Bewegung des ersten Hebelelements wird über das zweite Hebelelement das Lagergehäuse um eine vorzugsweise vertikal verlaufende Schwenkachse geschwenkt. Ein Anschlag, welcher insbesondere dem Tragelement zugeordnet ist, begrenzt dabei die Bewegung des Lagergehäuses. Dabei kann der Anschlag auf das Lagergehäuse und/oder auf das zweite Hebelelement wirken. Damit umfasst sind auch Anbauteile, welche mit dem Lagergehäuse und/oder mit dem zweiten Hebelelement verbunden sind. Dies kann etwa ein leicht auswechselbares Verschleißstück sein, welches an dem Lagergehäuse oder dem Hebelelement angebracht sein kann.A second lever element can therefore be moved by a first lever element, the second lever element being arranged pivotably on the bearing housing. Due to the movement of the first lever element, the bearing housing is pivoted about a preferably vertically extending pivot axis via the second lever element. A stop, which is assigned in particular to the support element, limits the movement of the bearing housing. The stop can act on the bearing housing and / or on the second lever element. This also includes add-on parts which are connected to the bearing housing and / or to the second lever element. This can be, for example, an easily replaceable wear piece, which can be attached to the bearing housing or the lever element.

Durch das Vorsehen von zwei gelenkig miteinander verbundenen Hebelelementen kann durch eine passend gewählte Übersetzung eine kleine Bewegung des ersten Hebelelements in eine Andrückkraft übersetzt werden, mit welcher das Lagergehäuse oder das zweite Hebelelement gegen den Anschlag andrückbar ist. Besonders vorteilhaft ist dabei, dass die Andrückkraft vergleichsweise groß sein kann, was zu einer erhöhten Stabilität des gesamten Farbwerks führt. Dadurch können Schwingungen des Farbwerkszylinders vermieden werden, welche im Stand der Technik für Schwingungsstreifen im Druck verantwortlich sind. Insgesamt kann also durch die Erfindung die Qualität der Druckerzeugnisse gesteigert werden.By providing two articulated lever elements, a small movement of the first lever element can be translated into a pressing force with which the bearing housing or the second lever element against the Stop can be pressed. It is particularly advantageous that the pressing force can be comparatively large, which leads to increased stability of the entire inking unit. As a result, vibrations of the inking cylinder can be avoided, which in the prior art are responsible for vibration strips in the print. Overall, the quality of the printed products can thus be increased by the invention.

In einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Schwenkachse in einer Ebene angeordnet ist, welche senkrecht zur Drehachse des Farbwerkszylinders liegt. Damit kann ein platzsparender Aufbau des Farbwerks erreicht werden. In weiterer Ausgestaltung eines erfindungsgemäßen Farbwerks kann das Tragelement relativ zu einem Maschinenstell insbesondere auf Führungen in einer Verschieberrichtung verschiebbar sein. In diesem Fall ist es vorteilhaft, wenn die Schwenkachse auch senkrecht zu dieser Verschieberichtung verläuft.In an advantageous embodiment of the invention it is provided that the pivot axis is arranged in a plane which is perpendicular to the axis of rotation of the inking cylinder. A space-saving construction of the inking unit can thus be achieved. In a further embodiment of an inking unit according to the invention, the support element can be displaceable relative to a machine position, in particular on guides in a direction of displacement. In this case it is advantageous if the pivot axis also runs perpendicular to this direction of displacement.

Weiterhin ist es bevorzugt, wenn das erste Hebelelement linear bewegbar in dem Tragelement gelagert ist, wobei mit der linearen Bewegung eine Schwenkbewegung des Lagergehäuses hervorrufbar ist. Eine lineare Bewegung ist leicht handhabbar. Diese kann beispielsweise manuell erfolgen. Insbesondere kann aber auch ein Linearzylinder oder ein Linearmotor sein. Ein Linearzylinder kann beispielsweise ein Pneumatikzylinder, insbesondere ein doppelt wirkender Pneumatikzylinder, sein.Furthermore, it is preferred if the first lever element is mounted in a linearly movable manner in the support element, with the linear movement being able to cause a pivoting movement of the bearing housing. A linear movement is easy to handle. This can be done manually, for example. In particular, however, can also be a linear cylinder or a linear motor. A linear cylinder can be, for example, a pneumatic cylinder, in particular a double-acting pneumatic cylinder.

In einer vorteilhaften Weiterbildung der Erfindung ist die Bewegung des ersten Hebelelements durch zumindest eine Begrenzungseinrichtung begrenzbar. Eine solche Begrenzungseinrichtung kann ein weiterer Anschlag sein. Die Begrenzungseinrichtung kann aber auch durch den Hub des Pneumatikzylinders definiert sein, also durch die Endpunkte des innerhalb des Pneumatikzylinders bewegbaren Kolbens. Durch die Begrenzung der Bewegung wird verhindert, dass die Andrückkraft wieder übermäßig reduziert wird. Ein solcher Fall wird weiter unten anhand der Figuren erläutert.In an advantageous development of the invention, the movement of the first lever element can be limited by at least one limiting device. Such a limiting device can be a further stop. However, the limiting device can also be defined by the stroke of the pneumatic cylinder, that is to say by the end points of the piston which can be moved within the pneumatic cylinder. Limiting the movement prevents the pressing force from being excessively reduced again. Such a case is explained below with reference to the figures.

In einer bevorzugten Ausführungsform der Erfindung ist es vorgesehen, dass wenn das Lagergehäuse und/oder das zweite Hebelelement an dem Anschlag anliegt, das erste Hebelelement weiter bewegbar ist, wobei mit dem ersten Hebelarm eine Position, in der das erste Hebelelement und das zweite Hebelelement in einem Gleichgewicht zueinander stehen, überschreitbar ist. In diesem Fall nehmen das erste Hebelelement und das zweite Hebelelement einen spitzen Winkel ein. Dieses Gleichgewicht ist in der Regel ein labiles Gleichgewicht, welches entsteht, wenn beispielsweise das erste Hebelelement und das zweite Hebelelement genau senkrecht zueinander stehen. In diesem Fall ist die Andrückkraft maximal. Diese Position wird oft auch als Totpunkt bezeichnet. Wird während der Bewegung des ersten Hebelelements diese Position überschritten und ist die zudem die Bewegung des ersten Hebelelements nach dem Überschreiten dieser Position begrenzt, so drückt weiterhin das erste Hebelelement das zweite Hebelelement und/oder das Lagergehäuse mit der Andrückkraft gegen den Anschlag. Die Gegenkraft zur Andrückkraft drückt nun das erste Hebelelement gegen die Begrenzungseinrichtung, so dass insgesamt eine sehr stabile Arretierung des Lagergehäuses an dem Tragelement erfolgt. Somit werden Schwingungen des Farbwerkszylinders weiter reduziert und die Qualität des Druckerzeugnisses weiter verbessert.In a preferred embodiment of the invention, it is provided that when the bearing housing and / or the second lever element bears against the stop, the first lever element can be moved further, with the first lever arm in a position in which the first lever element and the second lever element in to be in equilibrium with one another, can be exceeded. In this case, the first lever element and the second lever element assume an acute angle. This equilibrium is generally an unstable equilibrium which arises when, for example, the first lever element and the second lever element are exactly perpendicular to one another. In this case, the pressure is maximum. This position is often referred to as dead center. If this position is exceeded during the movement of the first lever element and the movement of the first lever element is also limited after this position has been exceeded, the first lever element continues to press the second lever element and / or the bearing housing with the pressing force against the stop. The counterforce to the pressing force now presses the first lever element against the limiting device, so that overall a very stable locking of the bearing housing on the support element takes place. Vibrations of the inking cylinder are thus further reduced and the quality of the printed product is further improved.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das Tragelement als Schlitten ausgestaltet ist, welcher relativ zu einem Farbwerksträger verschiebbar ist. Der Farbwerksträger kann dabei Bestandteil eines Druckmaschinengestells sein oder an diesem befestigt sein. Durch diese Ausgestaltung ist es beispielsweise möglich, äußere Hülsen mit stark unterschiedlichen Durchmessern zu verwenden und anschließend den Farbwerkzylinder durchmesserabhängig durch Verschiebung des Schlittens zu positionieren, beispielsweise relativ zu anderen Druckwerkzylindern. In diesem Zusammenhang weist die Erfindung durch die Schwenkbarkeit des Lagergehäuses im Gegensatz zu vielen anderen aus dem Stand der Technik bekannten Lösungen den Vorteil auf, dass zum Freilegen eines Zapfens des Farbwerkzylinders das Tragelement nicht verschoben werden muss. Dies ist insbesondere vorteilhaft bei einer Rasterwalze, welche durch eine Rakelkammer eingefärbt ist. Eine solche Rakelkammer in der Regel an den Tragelementen, welche die Enden des Farbwerkszylinders lagen, angeschlagen.In a preferred embodiment of the invention it is provided that the support element is designed as a slide which is displaceable relative to an inking unit carrier. The inking unit carrier can be part of a printing press frame or can be attached to it. This configuration makes it possible, for example, to use outer sleeves with widely differing diameters and then to position the inking cylinder depending on the diameter by moving the carriage, for example relative to other printing unit cylinders. In this context, the pivoting of the bearing housing, in contrast to many other solutions known from the prior art, has the advantage that the support element does not have to be displaced to expose a journal of the inking cylinder. This is particularly advantageous in the case of an anilox roller, which is characterized by a Doctor chamber is inked. Such a doctor chamber usually struck on the support elements, which were the ends of the inking cylinder.

Die oben genannte Aufgabe wird auch gelöst durch ein Verfahren zum Befestigen wenigstens eines Farbwerkszylinders an wenigstens einem Tragelement eines Farbwerks, mit einem Lagergehäuse, welchem zumindest ein ein Zapfen des Farbwerkszylinders rotierbar lagerndes Lager zugeordnet ist, wobei das Lagergehäuse relativ zum Tragelement um wenigstens eine Schwenkachse geschwenkt wird, um den Zapfen des Farbwerkszylinders freizulegen oder zu lagern, mit einer Arretiervorrichtung, mit welcher das Lagergehäuse an dem Tragelement festgelegt wird, wobei sich das Verfahren dadurch auszeichnet, dass die Arretiervorrichtung wenigstens zwei gelenkig miteinander verbundene Hebelelemente umfasst, wobei ein erstes Hebelelement in dem Tragelement gelagert ist und relativ zu diesem bewegt wird und ein zweites Hebelelement schwenkbar an dem Lagergehäuse gelagert ist, wobei die Arretiervorrichtung einen Anschlag für das Lagergehäuse und/oder das zweite Hebelelement umfasst, wobei die Hebelelemente bewegt werden und miteinander verbunden sind, dass das Lagergehäuse und/oder der zweite Hebelarm mit einer Andrückkraft gegen den Anschlag angedrückt werden.The above-mentioned object is also achieved by a method for fastening at least one inking unit cylinder to at least one support element of an inking unit, with a bearing housing to which at least one bearing rotatably supporting a journal of the inking unit cylinder is assigned, the bearing housing being pivoted about at least one pivot axis relative to the support element is to expose the journal of the inking cylinder or to store, with a locking device with which the bearing housing is fixed to the support element, the method being characterized in that the locking device comprises at least two articulated lever elements, a first lever element in the Carrying element is mounted and is moved relative to this and a second lever element is pivotally mounted on the bearing housing, the locking device comprising a stop for the bearing housing and / or the second lever element, wherein the lever elements be egt and connected to each other that the bearing housing and / or the second lever arm are pressed against the stop with a pressing force.

Mit dem erfindungsgemäßen Verfahren werden dieselben Vorteile erzielt, wie sie im Zusammenhang mit dem erfindungsgemäßen Druckwerk erzielt werden.The same advantages are achieved with the method according to the invention as are achieved in connection with the printing unit according to the invention.

Die Figur 1 zeigt eine Sicht auf das erfindungsgemäße Farbwerk 1 mit einem Farbwerkszylinder 2 und einem Lagergehäuse 3, in welchem der Zapfen 4 des Farbwerkszylinders lagerbar ist. Dazu weist das Lagergehäuse 3 ein in dieser Figur nicht sichtbares Lager auf, welche den Zapfen 4 umgibt. In diesem Zustand ist das Farbwerk betreibbar. Das Lagergehäuse 3 ist um die Drehachse 5 schwenkbar. Die Drehachse 5, welche durch ein Drehlager verkörperbar ist, stütz sich auf einem Tragelement 6 ab und kann beispielsweise durch eine Höhenverstelleinrichtung in ihrer Höhenposition relativ zum Tragelement verstellbar sein. Dadurch ist es möglich, den Farbwerkszylinder auszurichten. Das Tragelement stützt sich auf nicht gezeigten Bestandteilen eines Maschinengestells ab und wird im Druckbetrieb in der Regel relativ zu diesem unbeweglich gehalten. Das Tragelement 6 trägt ein Ansatzstück 7, welches auch einstückig mit dem Tragelement 6 ausgebildet sein kann. In oder an dem Ansatzstück ist ein erstes Hebelelement 8 linear in Richtung des Doppelpfeils 9 mittels eines nicht gezeigten Verschiebeantriebs verschiebbar, wobei das erste Hebelelement 8 gelenkig mit einem zweiten Hebelelement 10 verbunden ist. Hierzu dient ein erstes Gelenk 11. Mit einem zweiten Gelenk 12 ist das zweite Hebelelement 10 mit dem Lagergehäuse gelenkig verbunden. In der in der Fig.1 gezeigten Position liegt das Hebelelement 10 nahe dem Gelenk 12 an einer Anschlagkante 13 des Ansatzstücks 7 an. Dabei nehmen das erste Hebelelement 8 und das zweite Hebelelement 10 einen spitzen Winkel α ein, also einen Winkel von weniger als 90 ein, bevorzugt zwischen 80 und 89 Grad, insbesondere zwischen 85 und 89 Grad. Da das erste Hebelelement 11 in seiner Bewegung durch eine nicht dargestellte Begrenzungseinrichtung begrenzt ist, kann eine Kraft, die beispielsweise von dem Farbwerkszylinder 2 auf das Lagergehäuse 3 übertragen werden, zwar auf das erste Hebelelement 8 übertragen werden, führt aber zu keiner Bewegung des Lagergehäuses 3 relativ zum Tragelement 6. Damit ist eine hohe Druckqualität erreichbar.The Figure 1 shows a view of the inking unit 1 according to the invention with an inking cylinder 2 and a bearing housing 3, in which the pin 4 of the inking cylinder can be stored. For this purpose, the bearing housing 3 has a bearing which is not visible in this figure and which surrounds the pin 4. The inking unit can be operated in this state. The bearing housing 3 is pivotable about the axis of rotation 5. The axis of rotation 5, which can be embodied by a rotary bearing, is supported on a support element 6 and can be adjustable in its height position relative to the support element, for example, by means of a height adjustment device. This makes it possible to align the inking cylinder. The support element is based on components, not shown, of a machine frame and is generally held immovable relative to the latter during printing operation. The support element 6 carries an extension 7, which can also be formed in one piece with the support element 6. In or on the extension piece, a first lever element 8 can be displaced linearly in the direction of the double arrow 9 by means of a displacement drive (not shown), the first lever element 8 being connected in an articulated manner to a second lever element 10. A first joint 11 is used for this purpose. The second lever element 10 is articulated to the bearing housing by means of a second joint 12. In the in the Fig. 1 In the position shown, the lever element 10 lies close to the joint 12 on a stop edge 13 of the extension 7. The first lever element 8 and the second take Lever element 10 an acute angle α, that is, an angle of less than 90 a, preferably between 80 and 89 degrees, in particular between 85 and 89 degrees. Since the movement of the first lever element 11 is limited by a limiting device (not shown), a force that is transmitted, for example, from the inking cylinder 2 to the bearing housing 3 can be transmitted to the first lever element 8, but does not lead to any movement of the bearing housing 3 relative to the support element 6. A high print quality can thus be achieved.

In der Figur 2 wurde nun im Vergleich zur Figur 1 das erste Hebelelement von dem Farbwerkszylinder 2 weg bewegt, so dass nun das erste Hebelelement und das zweite Hebelelement einen stumpfen Winkel α zueinander einnehmen. Damit wurde ebenfalls das Lagergehäuse 3 durch ein Schwenken um die Drehachse 5 abgeschwenkt, so dass nun der Zapfen 4 freiliegt und beispielsweise eine äußere Hülse des Farbwerkszylinders 2 abziehbar ist. Dazu ist es nicht erforderlich, den das Tragelement relativ zum Farbwerkzylinder zu bewegen.In the Figure 2 has now been compared to Figure 1 the first lever element moves away from the inking cylinder 2, so that the first lever element and the second lever element now form an obtuse angle α to one another. Thus, the bearing housing 3 was also pivoted away by pivoting about the axis of rotation 5, so that the pin 4 is now exposed and, for example, an outer sleeve of the inking cylinder 2 can be removed. It is not necessary to move the support element relative to the inking cylinder.

Die Figur 3 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Farbwerks 1. Zusätzlich zeigt diese Figur einen Schnitt durch einen Teil des Lagergehäuses 3, so dass man verschiedene Funktionen innerhalb des Farbwerks 1 besser erkennen kann. Wenigstens ein Lager 14 ist beispielsweise als Rollenlager ausgestaltet und in oder an einem Lagerhalter 15 befestigt. Dieser Lagerhalter 15 ist beispielsweise entlang von Gleitflächen relativ zum Lagergehäuse 3 verschiebbar, wobei der Lagerhalter 15 und damit das wenigstens eine Lager 14 auf den Zapfen 4 aufschiebbar ist, so dass sich dieses und mit ihm der Farbwerkszylinder 2 nicht mehr in radialer Richtung relativ zum Lagergehäuse 3 bewegen kann.The Figure 3 shows a further embodiment of an inking unit 1 according to the invention. In addition, this figure shows a section through part of the bearing housing 3, so that different functions within the inking unit 1 can be better recognized. At least one bearing 14 is designed, for example, as a roller bearing and is fastened in or on a bearing holder 15. This bearing holder 15 can be displaced, for example, along sliding surfaces relative to the bearing housing 3, the bearing holder 15 and thus the at least one bearing 14 being able to be pushed onto the pin 4, so that the latter and with it the inking cylinder 2 are no longer in the radial direction relative to the bearing housing 3 can move.

Zum Verschieben des Lagerhalters 15 ist ein Antrieb 16 vorgesehen, welcher insbesondere vom Lagergehäuse 3 umfasst ist. Der Antrieb 16 kann als Kolbenzylindereinheit ausgestaltet sein und mittels einer am Kolben 17 befestigten Schub-/Zugstange 18 den Lagerhalter 15 verschieben.To move the bearing holder 15, a drive 16 is provided, which is particularly encompassed by the bearing housing 3. The drive 16 can be configured as a piston-cylinder unit and can move the bearing holder 15 by means of a push / pull rod 18 attached to the piston 17.

Die Figur 4 zeigt die Ausführungsform der Figur 3, wobei jedoch der Lagerhalter 15 von dem Zapfen 4 abgezogen ist. In diesem Zustand kann nun das Lagergehäuse abgeschwenkt werden, wie es bereits im Zusammenhang mit den Figuren 1 und 2 beschrieben wurde.The Figure 4 shows the embodiment of the Figure 3 , however, the bearing holder 15 is withdrawn from the pin 4. In this state, the bearing housing can now be swiveled away, as already in connection with the Figures 1 and 2 has been described.

Die Figur 5 zeigt eine Weiterbildung eines erfindungsgemäßen Farbwerks 1, insbesondere eines nach den Figuren 3 und 4. Diese vorteilhafte Weiterbildung umfasst wiederum einen am Lagergehäuse angeordneten Antrieb 16, mit welchem insbesondere ein Lager 14 auf den Zapfen 4 aufschiebbar und wieder vom Zapfen 4 abziehbar ist. Über eine beliebig geartete Verbindung, insbesondere einer mechanischen Verbindung, kann mittels des Antriebs 16 ein Schutzelement 20 verschiebbar sein. Insbesondere kann das Lager 14 in einem Lagerhalter 15 angeordnet sein und der Lagerhalter 15 einen Stift 21 umfassen, welcher beispielsweise durch ein Langloch 22 aus dem Lagergehäuse 3 herausragt. Dieser Stift 21 ist entsprechend mit dem Lagerhalter 15 verschiebbar. Der Stift 21 kann auch direkt einer Schub-/Zugstange 18 eines als Kolbenzylindereinheit ausgestalteten Antriebs 16 angeordnet sein.The Figure 5 shows a development of an inking unit 1 according to the invention, in particular one according to the Figures 3 and 4 . This advantageous development in turn comprises a drive 16 arranged on the bearing housing, with which in particular a bearing 14 can be pushed onto the pin 4 and can be removed again from the pin 4. A protective element 20 can be displaceable by means of the drive 16 via an arbitrary type of connection, in particular a mechanical connection. In particular, the bearing 14 can be arranged in a bearing holder 15 and the bearing holder 15 can comprise a pin 21 which, for example, protrudes from the bearing housing 3 through an elongated hole 22. This pin 21 can be moved accordingly with the bearing holder 15. The pin 21 can also be arranged directly on a push / pull rod 18 of a drive 16 designed as a piston-cylinder unit.

Das Schutzelement 20 umfasst insbesondere einen Halter 23 sowie den eigentlichen Schutz 24, welcher vom Halter 23 gehalten wird. Ein solcher Schutz 24 kann Teile der Stirnseite und/oder Teile der Umfangsfläche in Stirnseitennähe des Farbwerkzylinders 2 abdecken, so dass beispielsweise eine Berührung des Farbwerkzylinders 2 durch einen Bediener vermieden wird. Auch kann ein solcher Schutz ein Spritzschutz sein, wobei insbesondere vermieden wird, dass Farbe von dem Farbwerkzylinder in die Umgebung gelangt. Dies ist vor allem dann vorteilhaft, wenn der Farbwerkzylinder als Rasterwalze ausgestaltet ist. Der Halter 23 ist mit dem Stift wirkverbunden, d. h. bei einer Bewegung des Stifts wird auch der Halter und mit ihm der Schutz bewegt. Der Halter kann dabei auf einer Gleitfläche, welche sich beispielsweise auf einer Außenoberfläche des Lagergehäuses 3 befindet, gleiten. Mit dieser Ausgestaltung eines erfindungsgemäßen Farbwerks kann das Schutzelement automatisch zusammen mit der Bewegung des Antriebs und insbesondere zusammen mit dem Lager 14 von dem Farbwerkzylinder entfernt werden. Eine separate oder gar manuelle Entfernung des Schutzelements ist nicht mehr notwendig.The protective element 20 includes in particular a holder 23 and the actual protection 24, which is held by the holder 23. Such protection 24 can cover parts of the end face and / or parts of the circumferential surface in the vicinity of the end face of the inking cylinder 2, so that, for example, an operator does not touch the inking cylinder 2. Such protection can also be a splash guard, in particular avoiding that ink gets into the environment from the inking cylinder. This is particularly advantageous if the inking cylinder is designed as an anilox roller. The holder 23 is operatively connected to the pin, ie when the pin moves, the holder and the protection are moved with it. The holder can slide on a sliding surface, which is located on an outer surface of the bearing housing 3, for example. With this embodiment of an inking unit according to the invention, the protective element can be automatically removed from the inking unit cylinder together with the movement of the drive and in particular together with the bearing 14. A separate or even manual removal of the protective element is no longer necessary.
