Description

Druckmaschine sowie Verfahren zur Lageeinstellung ihres Druckwerks Printing machine and method for adjusting the position of their printing unit
Die vorliegende Erfindung betrifft eine Druckmaschine mit einem Druckwerk, das zumindest eine Walze sowie einen Gegendruckzylinder aufweist, wobei die Walze auf gegenüberliegenden Seiten mittels zweier Lager an einem Gestell drehbar gelagert ist und wobei eine Einstellvorrichtung zur Einstellung der Lage der Walze relativ zum Gegendruckzylinder vorgesehen ist. Die Erfindung betrifft ferner ein Verfahren zur Lageeinstellung des Druckwerks einer Druckmaschine, bei dem zumindest eine Walze des Druckwerks durch Verstellung der Lager auf gegenüberliegenden Seiten der Walze im Wesentlichen parallel zu einem Gegendruckzylinder des Druckwerks ausgerichtet wird.The present invention relates to a printing press with a printing unit, which has at least one roller and a counter-pressure cylinder, wherein the roller is rotatably mounted on opposite sides by means of two bearings on a frame and wherein an adjustment for adjusting the position of the roller is provided relative to the impression cylinder. The invention further relates to a method for adjusting the position of the printing unit of a printing press, wherein at least one roller of the printing unit is aligned by adjusting the bearings on opposite sides of the roller substantially parallel to a counter-pressure cylinder of the printing unit.
Beim Aufstellen einer Druckmaschine, aber auch nach Wartungs- oder Reparaturarbeiten bzw. einem Umrüsten einer Druckmaschine, wie beispielsweise einer formatvariablen Flexodruckmaschine, müssen die am Druck beteiligten Walzen des Druckwerks zueinander justiert werden. Als Fixpunkt bzw. feste Achse, bezüglich derer die Walzen justiert werden, wird oft der Gegendruckzylinder genommen, was sich vor allem bei Zentralzylindermaschinen mit mehreren Druckwerken anbietet. Hiervon ausgehend werden die Walzen der einzelnen Druckwerke justiert, so dass alle Walzenachsen parallel zueinander ausgerichtet sind, um letztendlich ein hochwertiges Druckbild zu erhalten.When setting up a printing machine, but also after maintenance or repair work or retooling a printing press, such as a variable-format flexographic printing press, the rollers involved in the printing of the printing unit must be adjusted to each other. As a fixed point or fixed axis, with respect to which the rollers are adjusted, the impression cylinder is often taken, which offers itself especially in central cylinder machines with multiple printing units. On this basis, the rollers of the individual printing units are adjusted, so that all roller axes are aligned parallel to each other, in order to ultimately obtain a high-quality printed image.
Hierzu werden regelmäßig die Walzen auf ihren beiden Seiten in die jeweiligenFor this purpose, the rollers are regularly on their two sides in the respective
Lager eingesetzt und eine Lagergrundplatte solange relativ zu dem den Gegendruckzylinder tragenden Maschinengestell über Einstellhilfen in Form vonUsed bearing and a bearing base plate as long as relative to the counter-pressure cylinder supporting machine frame on adjustment aids in the form of
Einstellschrauben justiert, bis die Walzenachsen parallel zu dem Gegendruckzylinder ausgerichtet sind. Diese Prozedur ist zeitaufwendig, komplex und anspruchsvoll.Adjusting screws adjusted until the roller axes parallel to the Counter-pressure cylinders are aligned. This procedure is time consuming, complex and demanding.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine verbesserte Druckmaschine der eingangs genannten Art sowie ein verbessertes Verfahren zur Lageeinstellung des Druckwerks einerOn this basis, the present invention has the object, an improved printing machine of the type mentioned above and an improved method for adjusting the position of the printing of a
Druckmaschine zu schaffen, die Nachteile des Standes der Technik vermeiden und letzteren in vorteilhafter Weise weiterbilden. Vorzugsweise soll eine verkürzte Montagezeit für die Lageeinstellung der Druckwerkswalzen erreicht werden.To provide printing machine, avoid the disadvantages of the prior art and further develop the latter in an advantageous manner. Preferably, a shortened assembly time for the position adjustment of the printing unit rollers should be achieved.
Erfindungsgemäß wird diese Aufgabe durch eine Druckmaschine gemäß Anspruch 1 gelöst. In verfahrenstechnischer Hinsicht wird die genannte Aufgabe durch ein Verfahren gemäß Anspruch 13 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention, this object is achieved by a printing press according to claim 1. In terms of process engineering, the stated object is achieved by a method according to claim 13. Preferred embodiments of the invention are the subject of the dependent claims.
Es wird also vorgeschlagen, die Lageeinstellung der beiden Lagerseiten einer jeweiligen Druckwerkswalze voneinander zu trennen und nacheinander zuerst die eine Lagerseite und dann die gegenüberliegende Lagerseite einzustellen. Insbesondere wird eine Winkeleinstellung auf nur einer Lagerseite vorgenommen, während die gegenüberliegende Lagerseite nur tangential und/oder radial zum Gegendruckzylinder verstellt wird. Erfindungsgemäß besitzt die Einstellvorrichtung der Druckmaschine für jedes der beiden Lager der zumindest einen Druckwerkswalze separate Lageeinstellmittel, mittels derer die Lage der Lager relativ zueinander sowie relativ zum Gestell, an dem die Druckwerkswalze gelagert ist, in zumindest eine Richtung quer zur Gegendruckzylinderlängsrichtung einstellbar sind. In verfahrenstechnischer Hinsicht wird in einem ersten Schritt die erste Lagerseite winkeleingestellt derart, dass das Lager auf der ersten Lagerseite mit seiner Drehachse möglichst parallel zur Gegendruckzylinderlängsachse ausgerichtet ist, wobei sodann in einem zweiten Schritt die zweite Lagerseite höheneingestellt wird derart, dass das Lager auf der zweiten Lagerseite zusammen mit dem Lager auf der ersten Lagerseite eine fluchtende Lagerachse parallel zur Gegendruckzylinderlängsachse bildet. Durch diese nacheinander ausgeführten, unterschiedlichen Einstellschritte wird die jeweils durchzuführende Einstellung beträchtlich weniger komplex und einfacher, wodurch insgesamt die gewünschte Ausrichtung der Walze beträchtlich schneller erreicht werden kann.It is therefore proposed to separate the position adjustment of the two bearing sides of a respective printing unit from each other and successively first set the one bearing side and then the opposite bearing side. In particular, an angle adjustment is made on only one bearing side, while the opposite bearing side is adjusted only tangentially and / or radially to the impression cylinder. According to the invention, the adjusting device of the printing machine has separate position adjusting means for each of the two bearings of the at least one printing unit roller, by means of which the position of the bearings relative to each other and relative to the frame on which the printing unit roller is mounted, in at least one direction are adjustable transversely to the impression cylinder longitudinal direction. In procedural terms, the first bearing side is angularly adjusted in a first step such that the bearing is aligned with its axis of rotation as parallel as possible to the impression cylinder longitudinal axis, then in a second step, the second bearing side is adjusted in height such that the bearing on the second Bearing side together with the bearing on the first bearing side forms an aligned bearing axis parallel to the impression cylinder longitudinal axis. Through these successively running, different adjustment steps, the particular setting to be made considerably less complex and easier, whereby the desired overall orientation of the roller can be achieved considerably faster overall.
In Weiterbildung der Erfindung vereinfacht sich der erste Schritt der Winkeleinstellung auf der ersten Lagerseite beträchtlich, wenn die Walze demontiert oder zumindest auf der gegenüberliegenden zweiten Lagerseite nicht in dem Lager montiert ist, so dass die Winkeleinstellung ohne Behinderung durch eine Fixierung auf der gegenüberliegenden Walzenseite durchgeführt werden kann. Gemäß einer bevorzugten Ausführung der Erfindung wird in dem ersten Schritt lediglich eine Lagerplatte, auf der ein das Lager tragender Lagerbock befestigbar ist, durch Winkeleinstellung parallel zum Gegendruckzylinder ausgerichtet. Der genannte Lagerbock kann dabei bereits auf die Lagerplatte aufgesetzt sein, jedoch vorteilhafterweise auch von der Lagerplatte demontiert sein.In a further development of the invention, the first step of the angular adjustment on the first bearing side considerably simplified when the roller is dismantled or at least not mounted in the bearing on the opposite second bearing side, so that the angle adjustment without obstruction by fixing on the opposite side of the roll are performed can. According to a preferred embodiment of the invention, in the first step, only one bearing plate, on which a bearing block carrying the bearing can be fastened, is aligned by angle adjustment parallel to the impression cylinder. The said bearing block can already be placed on the bearing plate, but advantageously also be dismantled from the bearing plate.
Nach erfolgter Winkeleinstellung auf der ersten Lagerseite wird sodann der Lagerpunkt auf der gegenüberliegenden zweiten Lagerseite entsprechend höheneingestellt. Hierzu wird vorteilhafterweise ein Exzenter verwendet, der das Lager auf der zweiten Lagerseite trägt. Durch Verdrehen des Exzenters kann die Lage des Lagerpunktes auf der genannten zweiten Lagerseite sehr feinfühlig eingestellt werden. Insbesondere kann exakt die Höhe des Lagerpunktes auf der zweiten Lagerseite relativ zu dem Lagerpunkt auf der ersten Lagerseite eingestellt werden, um der zwischen den beiden Lagerseiten eingesetzten Walze exakt eine parallele Ausrichtung zur Gegendruckzylinderlängsachse zu geben. Bei der Höheneinstellung durch Verdrehen des Exzenters auftretender Versatz in radialer Richtung bezüglich des Gegendruckzylinders kann in einem folgenden Verfahrensschritt durch Radialeinstellung des Exzenters kompensiert werden. Vorteilhafterweise umfassen die Einstellmittel auf der genannten zweiten Lagerseite zusätzlich zu dem Exzenter eine weitere Bewegungsachse radial zur Gegendruckzylinderlängsachse, so dass die Höheneinstellung und die Radialeinstellung auf der zweiten Lagerseite voneinander entkoppelt sind. Hierdurch kann zunächst eine exakte Justierung in Höhenrichtung vorgenommen werden, ohne auf eine dabei auftretende Verstellung in einer Richtung senkrecht dazu achten zu müssen. Ist die exakte Höheneinstellung gefunden, wird die radiale Lage des Lagerpunktes eingestellt, ohne auf die Höheneinstellung achten zu müssen.After the angle adjustment on the first bearing side of the bearing point is then adjusted accordingly height on the opposite second bearing side. For this purpose, an eccentric is advantageously used, which carries the bearing on the second bearing side. By turning the eccentric, the position of the bearing point on the said second bearing side can be adjusted very sensitively. In particular, exactly the height of the bearing point on the second bearing side can be adjusted relative to the bearing point on the first bearing side in order to give the roller inserted between the two bearing sides exactly parallel alignment with the impression cylinder longitudinal axis. In the height adjustment occurring by turning the eccentric offset in the radial direction with respect to the impression cylinder can be compensated in a subsequent process step by radial adjustment of the eccentric. Advantageously, the adjusting means on said second bearing side in addition to the eccentric comprise a further movement axis radially to the impression cylinder longitudinal axis, so that the height adjustment and the radial adjustment on the second bearing side are decoupled from each other. This allows first an exact adjustment in the height direction be made without having to pay attention to an occurring adjustment in a direction perpendicular thereto. Once the exact height setting has been found, the radial position of the bearing point is adjusted, without having to pay attention to the height adjustment.
Vorteilhafterweise sind den Einstellmitteln zumindest auf der zweiten Lagerseite Klemmmittel zugeordnet, um die jeweils eingestellte Lage des Lagers feststellen zu können und Lagerspiel beseitigen zu können. Insbesondere kann in Weiterbildung der Erfindung dem zuvor genannten Exzenter ein quer zur Drehachse des Exzentes wirkendes Feststellmittel, beispielsweise in Form einer Klemmschraube, zugeordnet sein, mittels dessen der Exzenter in der gefundenen Position festgestellt werden kann.Advantageously, the adjusting means are assigned at least on the second bearing side clamping means in order to determine the respectively set position of the bearing and to be able to eliminate bearing clearance. In particular, in the invention, the above-mentioned eccentric a transverse to the axis of rotation of the eccentric locking means, for example in the form of a clamping screw, be assigned, by means of which the eccentric can be determined in the found position.
Die Einstellmittel auf den beiden Lagerseiten können grundsätzlich verschieden ausgebildet sein. In Weiterbildung der Erfindung sind die Einstellmittel auf den beiden Lagerseiten zueinander unterschiedlich ausgebildet.The adjusting means on the two sides of the bearing can basically be designed differently. In a further development of the invention, the adjusting means on the two bearing sides are designed differently from one another.
Auf der zuvor genannten ersten Lagerseite können die Einstellmittel Höheneinstellmittel und/oder Winkeleinstellmittel zur Einstellung der Höhe und/oder der Winkelausrichtung des Lagers auf der genannten ersten Lagerseite aufweisen. Vorteilhafterweise greifen die genannten Einstellmittel auf der ersten Lagerseite zwischen dem Gestell und einer Lagerplatte an, auf der ein das Lager tragender Lagerbock längsverschieblich gelagert ist. Hierdurch kann zunächst die Lage der Lagerplatte in der gewünschten Weise eingestellt werden, insbesondere zu dem Gegendruckzylinder exakt parallel ausgerichtet werden. Der das Lager tragende Lagerbock ist auf der Lagerplatte vorteilhafterweise quer zur Längsachse des Gegendruckzylinders längsverschieblich gelagert, um die Walze auf den Gegendruckzylinder zustellen bzw. von diesem wegstellen zu können.On the aforesaid first bearing side, the adjusting means may comprise height adjusting means and / or angle adjusting means for adjusting the height and / or the angular orientation of the bearing on said first bearing side. Advantageously, said adjusting means engage on the first bearing side between the frame and a bearing plate on which a bearing bracket carrying the bearing is longitudinally displaceably mounted. In this way, first, the position of the bearing plate can be adjusted in the desired manner, in particular be aligned exactly parallel to the impression cylinder. The bearing block carrying the bearing is advantageously mounted longitudinally displaceably on the bearing plate transversely to the longitudinal axis of the impression cylinder in order to deliver the roller to the impression cylinder or to be able to move away from it.
Die Einstellmittel für die Lagerplatte können insbesondere zumindest eine Stellschraube umfassen, die im Wesentlichen senkrecht zur Ebene der Lagerplatte zustellbar ist, um hierdurch die Lage der Lagerplatte in der gewünschten Weise einstellen zu können. Vorteilhafterweise sind voneinander beabstandet mehrere Stellschrauben angeordnet, um in der gewünschten Weise sowohl eine Höheneinstellung der Lagerplatte als auch eine Winkeleinstellung der Lagerplatte feinfühlig vornehmen zu können. Die Winkeleinstellung der Lagerplatte ist dabei zumindest um eine Achse senkrecht zur Längsrichtung des Gegendruckzylinders und/oder der Walze möglich.The adjusting means for the bearing plate may in particular comprise at least one adjusting screw, which is deliverable substantially perpendicular to the plane of the bearing plate in order to thereby adjust the position of the bearing plate in the desired manner. Advantageously, are from each other spaced several screws arranged to make sensitive in the desired manner, both a height adjustment of the bearing plate and an angular adjustment of the bearing plate can. The angular adjustment of the bearing plate is possible at least about an axis perpendicular to the longitudinal direction of the impression cylinder and / or the roller.
Die Einstellmittel auf der gegenüberliegenden zweiten Lagerseite brauchen keine Winkeleinstellmittel zu umfassen, obwohl solche grundsätzlich auch auf der zweiten Lagerseite vorgesehen sein können. Insbesondere umfassen die Einstellmittel auf der zweiten Lagerseite als Höheneinstellmittel den vorgenannten Exzenter, der vorteilhafterweise als Exzenterhülse ausgebildet sein kann, in der das Lager der zweiten Lagerseite aufgenommen ist. Der Exzenter kann vorteilhafterweise um eine zur Walzenachse parallele Exzenterachse verdreht werden, um die gewünschte Höheneinstellung des Lagerpunktes zu erreichen.The adjustment means on the opposite second bearing side need not include Winkeleinstellmittel, although in principle may be provided on the second bearing side. In particular, the adjusting means on the second bearing side comprise as height adjusting means the aforementioned eccentric, which can be advantageously designed as an eccentric sleeve, in which the bearing of the second bearing side is accommodated. The eccentric can advantageously be rotated about an axis parallel to the roller axis eccentric axis in order to achieve the desired height adjustment of the bearing point.
Zusätzlich zu den vorteilhafterweise von dem Exzenter gebildeten Höheneinstellmittel sind in Weiterbildung der Erfindung auf der zweiten Lagerseite separate Radialeinstellmittel zur Einstellung der Position des Lagers radial zum Gegendruckzylinder vorgesehen. Diese Radialeinstellmittel können in Weiterbildung der Erfindung von einer Linearführung gebildet sein, denen ein geeignetes Stellmittel, beispielsweise in Form einer Stellspindel, zugeordnet ist.In addition to the height adjustment means advantageously formed by the eccentric separate radial adjustment means for adjusting the position of the bearing are provided radially to the impression cylinder in the invention on the second bearing side. This Radialeinstellmittel may be formed in a further development of the invention of a linear guide, which is associated with a suitable adjusting means, for example in the form of an adjusting spindle.

Auf der ersten Lagerseite 3, die die Antriebsseite bildet, ist die Walze 1 vorteilhafterweise durch ein Lager 6 drehbar gelagert, welches an einem Lagerbock 7 befestigt ist. Der Lagerbock 7 ist mittels einer Linearführung 8, die in der gezeichneten Ausführung als zweigleisige Schienenbettführung ausgebildet ist, längsverschieblich quer zur Walzenlängsachse 9 auf einer Lagerplatte 10 gelagert. Die Linearführung 8 erlaubt ein radiales Zustellen der Walze 1 zu einem nicht eigens dargestellten Gegendruckzylinder bzw. ein Wegfahren der Walze 1 von diesem Gegendruckzylinder. Der Linearführung 8 ist dabei eine Stellspindel 11 zugeordnet, die zwischen der genannten Lagerplatte 10 und dem Lagerbock 7 angreift.Figure 1 shows as a roll 1 of a printing unit 2, the format cylinder or the anilox roller of a flexographic printing press, which is rotatably mounted on opposite bearing sides 3 and 4 on a frame 5 about its longitudinal axis. On the first bearing side 3, which forms the drive side, the roller 1 is advantageously rotatably supported by a bearing 6 which is fixed to a bearing block 7. The bearing block 7 is mounted by means of a linear guide 8, which is formed in the illustrated embodiment as a double-rail track bed guide, longitudinally displaceable transversely to the roller longitudinal axis 9 on a bearing plate 10. The linear guide 8 allows a radial advancement of the roller 1 to a counter-pressure cylinder not shown specifically or a driving away of the roller 1 of this impression cylinder. The linear guide 8 is associated with an adjusting spindle 11 which acts between said bearing plate 10 and the bearing block 7.
Die genannte Lagerplatte 10 sitzt auf dem Gestell 5 und kann gegenüber diesem durch Einstellmittel 12 in Form mehrerer Stellschrauben 13 lageeingestellt werden. Die genannten Stellschrauben 13 greifen dabei im Wesentlichen senkrecht zu der von der Lagerplatte 10 definierten Ebene an dieser an und können die Lagerplatte 10 gegenüber dem Gestell 5 bewegen. Wie der Pfeil 14 andeutet, kann durch Justierung der Stellschrauben 13 eine Höheneinstellung, insbesondere aber auch eine Winkeleinstellung der Lagerplatte 10 um eine liegende Winkeleinstellachse senkrecht zur Zeichenebene der Figur 1 und damit auch senkrecht zur Walzenlängsachse bewirkt werden.Said bearing plate 10 is seated on the frame 5 and can be adjusted relative to this setting means 12 in the form of a plurality of screws 13. The aforementioned screws 13 engage substantially perpendicular to the plane defined by the bearing plate 10 at this and can move the bearing plate 10 relative to the frame 5. As indicated by the arrow 14, a height adjustment, but in particular also an angular adjustment of the bearing plate 10 by a horizontal Winkeleinstellachse perpendicular to the plane of the figure 1 and thus also perpendicular to the roll axis can be effected by adjusting the screws 13.
Auf der gegenüberliegenden zweiten Lagerseite 4 ist die Walze 1 durch ein Lager 15 drehbar gelagert, das selbst in einem Lagerträger 16 sitzt. Wie Figur 2 zeigt, ist das genannte Lager 15 an dem Lagerträger 16 durch eine Exzenterhülse 17 gelagert, in deren Innenausnehmung das Lager 15 sitzt und die mit ihrem Außenumfang in einer Lagerausnehmung des Lagerträgers 16 sitzt. Die Innenausnehmung der Exzenterhülse 17 ist dabei zur Exzenterdrehachse 18 radial versetzt, vgl. Figur 2. Wird die Exzenterhülse 17 in der Lagerausnehmung 19 in dem Lagerträger 16 verdreht, wie dies der Pfeil 20 in Figur 2 andeutet, erfährt das Lager 15 eine Höheneinstellung senkrecht zur Walzenlängsachse 9.On the opposite second bearing side 4, the roller 1 is rotatably supported by a bearing 15, which sits itself in a bearing carrier 16. As Figure 2 shows, said bearing 15 is mounted on the bearing bracket 16 by an eccentric sleeve 17, in whose inner recess the bearing 15 is seated and which sits with its outer circumference in a bearing recess of the bearing bracket 16. The inner recess of the eccentric sleeve 17 is offset radially to the eccentric rotation axis 18, cf. FIG. 2. If the eccentric sleeve 17 is rotated in the bearing recess 19 in the bearing carrier 16, as indicated by the arrow 20 in FIG. 2, the bearing 15 experiences a height adjustment perpendicular to the roller longitudinal axis 9.
Der Exzenter in Form der Exzenterhülse 17 ist dabei vorteilhafterweise derart ausgebildet, dass eine Lagerverstellung aus der in Figur 2 gezeigten Mittelstellung von zumindest 0,25 mm, vorteilhafterweise von etwa 0,3 mm bis 1 mm, sowohl nach oben als auch nach unten möglich ist.The eccentric in the form of the eccentric sleeve 17 is advantageously designed such that a bearing adjustment from the middle position shown in Figure 2 of at least 0.25 mm, advantageously from about 0.3 mm to 1 mm, both upwards and downwards is possible ,
Die Exzenterhülse 17 kann in der jeweils eingestellten Stellung durch Klemmmittel 21 festgeklemmt werden, die vorteilhafterweise quer zur Exzenterdrehachse 18 wirken, um gleichzeitig ein Lagerspiel zu beseitigen Insbesondere kann, wie Figur 2 zeigt, als Klemmmittel 21 eine Klemmschraube 22 vorgesehen sein, mittels derer die Lagerausnehmung 19 in dem Lagerträger 16 zusammengespannt werden kann, um die Exzenterhülse 17 in der Lagerausnehmung 19 radial zu klemmen. Der Lagerträger 16 bildet hierzu vorteilhafterweise ein geschlitztes Lagerauge, in dem der Exzenter sitzt und das durch Zustellen der Klemmschraube 22 zusammengespannt werden kann, so das sich sein Durchmesser verjüngt.The eccentric sleeve 17 can be clamped in the respectively set position by clamping means 21, which act advantageously transversely to the eccentric rotation axis 18 to simultaneously eliminate a bearing clearance In particular, as shown in Figure 2, as clamping means 21, a clamping screw 22 may be provided by means of which the bearing recess 19 can be clamped together in the bearing bracket 16 to clamp the eccentric sleeve 17 in the bearing recess 19 radially. The bearing support 16 advantageously forms a slotted bearing eye, in which the eccentric sits and which can be clamped together by advancing the clamping screw 22, so that its diameter tapers.
Wie die Figuren 1 und 2 zeigen, kann der Lagerträger 16 durch Radial- Einstellmittel 23 quer zur Gegendruckzylinderlängsachse auf den Gegendruckzylinder zugestellt und von diesem weggestellt werden. Insbesondere kann durch diese separaten Radialeinstellmittel 23 ein Radialversatz ausgeglichen werden, der bei der Höheneinstellung durch Verdrehen des Exzenters auftritt. Wie Figur 1 und 2 zeigen, ist der Lagerträger 16 durch eine Linearführung 24, die in der gezeigten Ausführung als eingleisige Schienenbettführung ausgebildet ist, quer zur Walzenlängsachse 9 entlang der liegenden Linearführungsachse gegenüber dem Gestell 5 verstellbar. Der Linearführung 24 ist dabei ein Stellmittel 25 in Form einer Stellspindel zugeordnet, die zwischen dem Gestell 5 und dem Lagerträger 16 angreift. Zur Einstellung der Lage der Walze 1 wird dabei vorteilhafterweise folgendermaßen vorgegangen: Zunächst wird auf der ersten Lagerseite 3 die Lagerplatte 10 exakt parallel zu der Längsachse des Gegendruckzylinders ausgerichtet. Hierzu werden die Stellschrauben 13 entsprechend justiert, bis die gewünschte Ausrichtung der Lagerplatte 10 gefunden ist. Dabei kann der Lagerbock 7 auf der Lagerplatte 10 aufgesetzt sein, vorteilhafterweise kann er jedoch auch davon abgenommen sein.As shown in Figures 1 and 2, the bearing support 16 can be delivered by radial adjusting means 23 transversely to the impression cylinder longitudinal axis of the impression cylinder and placed away from it. In particular, a radial offset can be compensated by this separate Radialeinstellmittel 23, which occurs in the height adjustment by turning the eccentric. As shown in FIGS. 1 and 2, the bearing carrier 16 is adjustable relative to the frame 5 transversely to the roller longitudinal axis 9 along the linear guide axis lying by a linear guide 24, which in the illustrated embodiment is designed as a single rail track bed guide. The linear guide 24 is assigned an adjusting means 25 in the form of an adjusting spindle which engages between the frame 5 and the bearing bracket 16. To adjust the position of the roller 1, the procedure is advantageously as follows: First, the bearing plate 10 is aligned exactly parallel to the longitudinal axis of the impression cylinder on the first bearing side 3. For this purpose, the screws 13 are adjusted accordingly until the desired orientation of the bearing plate 10 is found. In this case, the bearing block 7 may be placed on the bearing plate 10, but advantageously it may also be removed therefrom.
Ist die erste Lagerseite 3 winkeleingestellt, wird auf der zweiten Lagerseite 4 zunächst durch Verdrehen des Exzenters 17 das Lager 15 der zweiten Lagerseite 4 höheneingestellt. Die Exzenterhülse 17 wird dabei so lange verdreht, bis die gewünschte Höhenlage gefunden ist und die Lager 15 und 6 auf den beiden Lagerseiten 3 und 4 in einer gemeinsamen Höhenebene liegen, die exakt parallel zu der Gegendruckzylinderlängsachse ist. Sodann wird der durch die Verdrehung des Exzenters auftretende Radialversatz durch die Stellspindel 15, die in eine entsprechende Radialbewegung des Lagerträgers 16 umgesetzt wird, ausgeglichen. Hierdurch kommt schließlich das Lager 15 in eine Lage, in der das Lager 15 und das Lager 6 auf den beiden Lagerseiten 3 und 4 eine fluchtende Lagerachse bilden, die exakt parallel zu dem Gegendruckzylinder ausgerichtet ist, so dass auch die zwischen den beiden Lagern 15 und 6 eingesetzte Druckwalze 1 parallel zu dem Gegendruckzylinder ausgerichtet ist.If the first bearing side 3 is angularly adjusted, the bearing 15 of the second bearing side 4 is first of all height-adjusted on the second bearing side 4 by turning the eccentric 17. The eccentric sleeve 17 is thereby rotated until the desired altitude is found and the bearings 15 and 6 lie on the two bearing sides 3 and 4 in a common height plane which is exactly parallel to the impression cylinder longitudinal axis. Then occurring by the rotation of the eccentric radial offset by the adjusting spindle 15, which is converted into a corresponding radial movement of the bearing support 16, balanced. As a result, finally, the bearing 15 comes into a position in which the bearing 15 and the bearing 6 on the two bearing sides 3 and 4 form an aligned bearing axis, which is aligned exactly parallel to the impression cylinder, so that between the two bearings 15 and 6 inserted pressure roller 1 is aligned parallel to the impression cylinder.
Die zur Höhenjustierung eingestellte Drehstellung der Exzenterhülse 17 ist zuvor durch Festziehen der Klemmschraube 22 eingefroren worden. The set for height adjustment rotational position of the eccentric sleeve 17 has previously been frozen by tightening the clamping screw 22.
