Description

Die Erfindung bezieht sich auf eine Einrichtung nach dem Hauptanspruch.The invention relates to a device according to the main claim.

In Druckmaschinen erstrecken sich Transportrahmen, auf denen Transportbänder gespannt sind. Auf den Transportbändern wird Bedruckstoff transportiert und von den nahe bei den Transportbändern angeordneten Druckmodulen mit betonerten Bildern versehen. Von entscheidender Bedeutung ist in diesem Zusammenhang die exakte Ausrichtung von Bedruckzylindern der Druckmodule zum Bedruckstoff. Wichtig ist, dass die schmale Auflagefläche der Bedruckzylinder am Bedruckstoff, die auch als Nip oder Druckspalt bezeichnet wird, mit hoher Genauigkeit am Bedruckstoff anliegt. Verschiebungen des Nips führen zu Druckfehlern am Bedrukkstoff, wie leicht verständlich. Der Stand der Technik schlägt zu dieser Thematik der Registersteuerung eine große Vielzahl von Lösungen vor, die sich im Wesentlichen auf die Steuerung des Registers oder Passers während des Druckmaschinenlaufs beziehen. Das Nip kann bezüglich dem Transportband oder Bedruckstoff jedoch bereits vor dem Druckbetrieb fehlausgerichtet sein. Die Registersteuerungen zur Steuerung der Registerhaltigkeit in Laufrichtung und quer zur Laufrichtung des Transportbands verändern im Fall einer Fehlausrichtung in Laufrichtung des Transportbandes etwa die Geschwindigkeit des Transportbands oder die Geschwindigkeit der Bedruckzylinder entsprechend, im Falle der Fehlausrichtung quer zur Laufrichtung des Transportbands wird etwa die Lage axial zu den Bedruckzylindern verändert. Fehlausrichtungen werden bis zu einem gewissen Maße korrigiert, doch eine Fehlausrichtung des Bedruckzylinders zum Transportband in Bezug auf die Höhe, d.h. der Abstand zwischen dem Bedruckzylinder und dem Transportband oder Bedruckstoff oder der Anpressdruck zwischen diesen wird nicht von Registersteuerungen gesteuert. Weiterhin bestehen mechanische Vorrichtungen, welche vor dem Druckvorgang den Rahmen mit dem Transportband in Richtung des Bandlaufs und in Richtung quer zum Bandlauf einstellen, um eine optimale Ausrichtung des Rahmens zu den Bedruckzylindern erstmals durchzuführen oder nach einer gewissen Betriebszeit der Druckmaschine wiederherzustellen und eine Fehlausrichtung oder ein Verziehen des Rahmens zu verhindern. Diese Vorrichtungen umfassen aufwendige Einstellkonstruktionen. Ein einstellbares Transportband für Druckexemplare in einer Druckmaschine ist aus dem Dokument DE-A-4 443 031 bekannt. Aufgabe der Erfindung ist, eine einfache Einrichtung zum Einstellen eines Druckmoduls einer Druckmaschine in Bezug auf einen Rahmen der Druckmaschine bereitzustellen. Die Aufgabe löst die Erfindung mit den Merkmalen des Hauptanspruchs, wobei eine Einrichtung zum Einstellen eines ein Transportband tragenden Rahmens einer Druckmaschine in Bezug zu Druckmodulen vorgesehen ist mit wenigstens einer ersten Führung am Rahmen zum Führen einer am Rahmen angeordneten Platte in waagerechter Richtung x längs zum Rahmen mittels eines ersten Führungselements zum Einstellen des Rahmens in entsprechender Richtung, wobei senkrecht an der Platte zwei Wände parallel zueinander angeordnet sind, die zweite Führungen in senkrechter Richtung y zum Rahmen aufweisen, an welchen zweite Führungselemente bewegbar sind, und zwischen den zweiten Führungselementen ein drittes Führungselement angeordnet ist, welches an dritten Führungen an den zweiten Führungselementen in Richtung z zur Plattenebene des Rahmens bewegbar ist.In printing machines, transport frames extend on which conveyor belts are tensioned. Printing material is transported on the conveyor belts and provided with concrete images by the printing modules arranged close to the conveyor belts. Of crucial importance in this context is the exact alignment of printing cylinders of the printing modules to the substrate. It is important that the narrow contact surface of the printing cylinder on the substrate, which is also known as nip or printing nip, with high accuracy rests on the substrate. Displacements of the nip lead to printing errors on the printing medium, as is easily understood. The prior art proposes to this topic of register control a wide variety of solutions, which essentially relate to the control of the register or register during printing press run. However, the nip may already be misaligned with respect to the conveyor belt or substrate before the printing operation. The register controls to control the registration in the direction and across the direction of the conveyor belt change in the event of misalignment in the direction of the conveyor belt about the speed of the conveyor belt or the speed of the printing cylinder accordingly, in the case of misalignment transverse to the direction of the conveyor belt is about the position axially changed the printing cylinders. Misalignments are corrected to some extent, but misalignment of the impression cylinder to the conveyor in relation to the height, ie the distance between the impression cylinder and the conveyor belt or substrate or the contact pressure therebetween, is not controlled by register controls. Furthermore, there are mechanical devices which set the frame with the conveyor belt in the direction of tape travel and in the direction transverse to the tape before printing to perform an optimal alignment of the frame to the printing cylinders for the first time or restore after a certain operating time of the printing press and a misalignment or To prevent warping of the frame. These devices include elaborate adjustment constructions. An adjustable conveyor for printed copies in a printing press is from the document DE-A-4 443 031 known. Task of The invention is to provide a simple means for adjusting a printing module of a printing press with respect to a frame of the printing press. The object is achieved by the invention with the features of the main claim, wherein a device for adjusting a conveyor belt frame of a printing press is provided with respect to pressure modules with at least a first guide on the frame for guiding a plate arranged on the frame in the horizontal direction x along the frame by means of a first guide element for adjusting the frame in a corresponding direction, perpendicular to the plate two walls are arranged parallel to each other, the second guides in the vertical direction y to the frame, on which second guide elements are movable, and between the second guide elements, a third guide element is arranged, which is movable on third guides on the second guide elements in the direction z to the plate plane of the frame.

Im folgenden ist eine Beschreibung in näheren Einzelheiten in Bezug auf die Figuren aufgeführt.

The following is a description in more detail with reference to the figures.
Fig. 1
shows a detail of a perspective view of a frame 1 with an embodiment of a device according to the invention,
Fig. 2
shows a plan view of the device of FIG. 1.

Fig. 1 stellt einen Ausschnitt einer Perspektivansicht eines Rahmens 1 einer Druckmaschine dar. Im Rahmen 1 sind Rollen 3 gelagert, an denen ein endloses Transportband oder Web anliegt und Papierbogen durch die Druckmaschine transportiert. Von erheblicher Bedeutung ist, dass das Transportband eine fehlerfreie Lage aufweist, auch in Bezug zu Druckzylindern, die bei dem Beispiel nach der Fig. 1 von oben am Transportband anliegen und an diesem abrollen. An der Platte 5 erstreckt sich wenigstens eine waagerechte erste Führung 2, wobei in Fig. 1 zwei horizontale erste Führungen 2 dargestellt sind. Entsprechend weist die Platte 5 erste Führungselemente 4 zum Eingreifen in die ersten Führungen 2 auf. Das Eingreifen der ersten Führungselemente 4 der Platte 5 in die ersten Führungen 2 ermöglicht ein horizontales Bewegen der Platte 5 entlang des Rahmens 1. Hierzu können die ersten Führungselemente 4 zum Eingreifen in die ersten Führungen 2 des Rahmens 1 in diesem hin- und hergleiten. Am Rahmen 1 ist die Platte 5 mittels ersten Feststellschrauben 6, welche durch erste Bohrungen 19 durch die Platte 5 greifen, angebracht. Mit der Platte 5 fest verbunden sind eine erste Seitenwand 13 und eine zweite Seitenwand 14, die beide senkrecht zur Platte 5 angeordnet sind und bevorzugt Aussparungen 25 aufweisen. Die erste Seitenwand 13 und die zweite Seitenwand 14 sind an deren Unterseiten durch eine Bodenwand 18 verbunden. An der Innenfläche der ersten Seitenwand 13 und an der Innenfläche der zweiten Seitenwand 14 befinden sich zweite Führungen 22. Die zweiten Führungen 22 der ersten Seitenwand 13 und der zweiten Seitenwand 14 greifen in ein zweites Führungselement 15 bzw. in ein zweites Führungselement 15' ein. Zwischen dem zweiten Führungselement 15 und dem zweiten Führungselement 15' befindet sich ein drittes Führungselement 17. Am dritten Führungselement 17 sind dritte Führungen 23 angebracht, welche auf der einen Seite in das zweite Führungselement 15 und auf der anderen Seite in das zweite Führungselement 15' eingreifen und das Hin- und Hergleiten des dritten Führungselements 17 zwischen dem zweiten Führungselement 15 und dem zweiten Führungselement 15' in z-Richtung in Richtung des Rahmens 1 ermöglichen. An der äußeren Stirnfläche des dritten Führungselements 17 ist ein Befestigungselement 21 angebracht. Das Befestigungselement 21 weist eine Bohrung zur Aufnahme eines Passstiftes 11 auf. An einer Seite weist das Befestigungselement 21 einen Anker 7 mit zweiten Bohrungen 20 an dessen Oberseite auf, an der anderen Seite den Passstift 11. Der Anker 7 ist mit dem Befestigungselement 21 durch eine Buchse/Pen-Verbindung verbunden, wobei sich am Befestigungselement 21 eine Buchse oder eine Aussparung, auch als Pit bezeichnet, befindet, in die der Pen oder Stift am Befestigungselement 21 eingreift und eine sichere Verbindung zwischen dem Befestigungselement 21 und dem Anker 7 herstellt. Durch Bohrungen durch die Bodenwand 18 erstrecken sich eine zweite Feststellschraube 9 und eine Einstellschraube 10. Die zweite Feststellschraube 9 greift von unten betrachtet hinter der Bodenwand 18 an der Unterseite des zweiten Führungselements 15 an. Das Gewinde der Einstellschraube 10 greift von unten betrachtet hinter der Bodenwand 18 in ein Gewinde in der Unterseite des zweiten Führungselements 15' ein. In einer Aussparung 25 der zweiten Seitenwand 14 befindet sich eine dritte Feststellschraube 29, die sich durch die zweite Seitenwand 14 erstreckt und an die der zweiten Seitenwand 14 zugewendeten Seitenwand des zweiten Führungselements 15' angreift. Die Funktion der Erfindung ist wie folgt. Wird festgestellt, dass das Nip oder der Druckspalt der Druckmaschine falsch eingestellt ist, d.h. der Bedruckzylinder zum Transportband falsch ausgerichtet ist, so gewährleistet die Einrichtung das mechanische Einstellen des Nips bezüglich des Transportbands. Diese Fehlausrichtungen treten beispielweise auf, wenn der Rahmen 1 bei der Wartung aus seiner Ruhelage bewegt wird. Eine Abweichung in die durch den x-Pfeil bezeichnete, etwa waagerechte Richtung längs zum Rahmen 1 wird durch Ziehen oder Drücken an dem Passstift 11 in x-Richtung korrigiert. Der Passstift 11 wird hierzu durch Ziehen aus seiner Sicherungslage entfernt, indem ein Zapfen des Passstifts 11 aus dem Befestigungselement 21 herausgezogen wird. Nun wird die Einrichtung durch Ziehen oder Drücken in x-Richtung nach links oder rechts nach Fig. 1 bewegt, dagegen bleibt der Rahmen 1 statisch. Das Ziehen oder Drücken bewirkt, dass sich die ersten Führungselemente 4 der Platte 5 in den ersten Führungen 2 mit der Platte 5 in die jeweilige waagerechte Richtung längs zum Rahmen 1 bewegen. Die zweiten Führungselemente 15, 15' und das dritte Führungselement 17 bleiben hierbei fest in ihrer Lage. Das Ziehen oder Drücken des Passstifts 11 bewirkt daher mittels einer Spannvorrichtung in den ersten Führungen 2 ein Verschieben des mit dem Anker 7 verbundenen Druckmoduls. Nachdem die Einrichtung in gewünschter Weise in x-Richtung verschoben ist, wird der Passstift 11 in seiner Sicherungslage eingerastet und das Druckmodul befindet sich in einer festgelegten Ausrichtung zum Rahmen 1. Da der Rahmen 1 fest bleibt und nicht verschoben wird, während der Anker 7 am Druckmodul bewegt wird, wird die Ausrichtung des Druckmoduls in Bezug auf den Rahmen 1 verändert und korrigiert. Die Einrichtung wird in Richtung des z-Pfeils in ähnlicher Weise wie vorstehend beschrieben verschoben. Die dritte Feststellschraube 29 wird zu diesem Zweck gelockert, d.h. die Anpresskraft der dritten Feststellschraube 29 seitlich an das zweite Führungselement 15' durch die zweite Seitenwand 14 wird verringert. Durch Drücken oder Ziehen des Passstifts 11 in Richtung des z-Pfeils bewegt sich das dritte Führungselement 17, das über das Befestigungselement 21 mit dem Passstift 11 verbunden ist, nach hinten bzw. nach vorne bezüglich der Betrachterebene nach Fig. 1. Hierbei gleitet das dritte Führungselement 17 an den dritten Führungen 23, welche aus dem zweiten Führungselement 15 und aus dem zweiten Führungselement 15' hervorstehen, entlang dieser. Das dritte Führungselement 17 weist hierzu Aussparungen auf, in welche die dritten Führungen 23 eingreifen, ähnlich wie die zweiten Führungen 22 in die zweiten Führungselemente 15, 15' eingreifen. Auf diese Weise ist das mit dem Anker 7 verbundene Druckmodul beidseitig in z-Richtung bewegbar, wobei der Rahmen 1 fest in seiner Lage verbleibt. Nachdem die Einrichtung in gewünschter Weise in z-Richtung verschoben ist, wird die dritte Feststellschraube 29 festgezogen, d.h. die Anpresskraft der dritten Feststellschraube 29 an das zweite Führungselement 15' wird erhöht und die eingestellte z-Richtung wird fixiert. Das Druckmodul befindet sich nun in einer festgelegten Ausrichtung zum Rahmen 1. Die beiden vorstehend beschriebenen Einstellungen der Einrichtung in die x-Richtung und in die z-Richtung sind nur beispielhaft, weitere Möglichkeiten, das dritte Führungselement 17 und die Platte 5 mit dem ersten Führungselement 4 zu bewegen sind denkbar, insbesondere Einstellungen mittels Mikrometerschrauben. Versuche haben jedoch ergeben, dass die Empfindlichkeit der vorstehend beschriebenen manuellen Einstellungen für die durch Einstellen des Druckmoduls im Verhältnis zum Rahmen 1 erzielte Registerhaltigkeit bei Druckmaschinen ausreichend sind. Abschließend ist das Einstellen der Einrichtung in y-Richtung beschrieben. Hierzu wird die zweite Feststellschraube 9 gelöst, welche in Ruhestellung der Einrichtung an das zweite Führungselement 15 angreift und die Einrichtung in y-Richtung fixiert. Nun ist die Bewegung der Einrichtung in y-Richtung senkrecht zum Rahmen 1 ermöglicht. Durch Drehen der Einstellschraube 10, die in ein Gewinde des zweiten Führungselements 15' eingreift, wird das zweite Führungselement 15' und mit diesem das zweite Führungselement 15 und das dritte Führungselement 17 nach oben verschoben, wobei die zweiten Führungselemente 15, 15' an den zweiten Führungen 22 entlang gleiten und das dritte Führungselement 17 an den zweiten Führungselementen 15, 15' befestigt ist und sich mit diesen bewegt. Die Einstellschraube 10 mit der entsprechenden Gewindebohrung im zweiten Führungselement 15' gestattet die Einstellung der Einrichtung in y-Richtung im Mikrometerbereich. Das Befestigungselement 21 ist, wie erwähnt, mit dem dritten Führungselement 17 verbunden, so dass das Druckmodul durch den Anker 7 am Befestigungselement 21 in y-Richtung nach oben oder nach unten verschoben wird. Nach dem genauen Einstellen der Position in y-Richtung im Mikrometerbereich wird die zweite Feststellschraube 9 in der Weise festgezogen, dass diese an das zweite Führungselement 15 angreift und dieses sowie das zweite Führungselement 15' und das dritte Führungselement 17 fixiert. Durch das Fixieren sind die Einrichtung und das Druckmodul in y-Richtung fixiert.Fig. 1 shows a detail of a perspective view of a frame 1 of a printing press. In the frame 1, rollers 3 are mounted on which an endless conveyor belt or web rests and transports paper sheets through the printing press. Of considerable importance is that the conveyor belt has a faultless position, also in relation to printing cylinders, which abut in the example of FIG. 1 from the top of the conveyor belt and roll on this. At least one horizontal first guide 2 extends on the plate 5, two horizontal first guides 2 being shown in FIG. Accordingly, the plate 5 has first guide elements 4 for engaging in the first guides 2. The engagement of the first guide elements 4 of the plate 5 in the first guides second allows horizontal movement of the plate 5 along the frame 1. For this purpose, the first guide elements 4 for engaging in the first guides 2 of the frame 1 in this slide back and forth. On the frame 1, the plate 5 by means of first locking screws 6, which engage through first holes 19 through the plate 5, attached. Securely connected to the plate 5 are a first side wall 13 and a second side wall 14, both of which are arranged perpendicular to the plate 5 and preferably have recesses 25. The first side wall 13 and the second side wall 14 are connected at their lower sides by a bottom wall 18. On the inner surface of the first side wall 13 and on the inner surface of the second side wall 14 are second guides 22. The second guides 22 of the first side wall 13 and the second side wall 14 engage in a second guide member 15 and in a second guide member 15 'a. A third guide element 17 is located between the second guide element 15 and the second guide element 15 '. Third guides 23 are attached to the third guide element 17, which engage on one side in the second guide element 15 and on the other side in the second guide element 15' and the back and forth sliding of the third guide member 17 between the second guide member 15 and the second guide member 15 'in the z- direction in the direction of the frame 1 allow. On the outer end face of the third guide member 17, a fastening element 21 is attached. The fastening element 21 has a bore for receiving a dowel pin 11. On one side, the fastening element 21 has an anchor 7 with second holes 20 at the top, on the other side of the dowel pin 11. The anchor 7 is connected to the fastening element 21 by a socket / pen connection, wherein the fastening element 21 a Socket or a recess, also referred to as pit, is located, in which the pen or pin engages the fastening element 21 and establishes a secure connection between the fastening element 21 and the armature 7. By drilling through the bottom wall 18, a second locking screw 9 and an adjusting screw 10 extend. The second locking screw 9 engages viewed from below behind the bottom wall 18 on the underside of the second guide member 15 at. The thread of the adjusting screw 10 engages behind the bottom wall 18 as viewed from below into a thread in the underside of the second guide element 15 'one. In a recess 25 of the second side wall 14 is a third locking screw 29 which extends through the second side wall 14 and to the second side wall 14 facing side wall of the second guide member 15 'engages. The function of the invention is as follows. If it is determined that the nip or printing nip of the printing press is set incorrectly, ie the printing cylinder is misaligned with the conveyor belt, the device ensures the mechanical adjustment of the nip with respect to the conveyor belt. These misalignments occur, for example, when the frame 1 is moved during maintenance from its rest position. A deviation in the approximately horizontal direction, designated by the x- arrow, along the frame 1 is corrected by pulling or pressing on the dowel pin 11 in the x- direction. The dowel pin 11 is removed for this purpose by pulling from its securing position by a pin of the dowel pin 11 is pulled out of the fastener 21. Now the device is moved by pulling or pressing in the x- direction to the left or right of FIG. 1, while the frame 1 remains static. The pulling or pushing causes the first guide elements 4 of the plate 5 in the first guides 2 to move with the plate 5 in the respective horizontal direction along the frame 1. The second guide elements 15, 15 'and the third guide member 17 remain fixed in their position. The pulling or pushing of the dowel pin 11 therefore causes by means of a tensioning device in the first guides 2 a displacement of the pressure module connected to the armature 7. After the device is shifted in the desired manner in the x- direction, the dowel pin 11 is locked in its backup position and the print module is in a fixed orientation to the frame 1. Since the frame 1 remains fixed and is not moved, while the anchor 7 am Print module is moved, the orientation of the printing module with respect to the frame 1 is changed and corrected. The device is displaced in the direction of the z -arrow in a manner similar to that described above. The third locking screw 29 is loosened for this purpose, ie the contact pressure of the third locking screw 29 laterally to the second guide member 15 'through the second side wall 14 is reduced. By pressing or pulling the dowel pin 11 in the direction of the z- arrow, the third guide element 17, which is connected via the fastening element 21 with the dowel pin 11, moves backwards or forwards with respect to the Viewer plane of FIG. 1. In this case, the third guide member 17 slides on the third guides 23, which protrude from the second guide member 15 and the second guide member 15 ', along this. For this purpose, the third guide element 17 has recesses into which the third guides 23 engage, similar to how the second guides 22 engage in the second guide elements 15, 15 '. In this way, the pressure module connected to the armature 7 is movable on both sides in the z- direction, wherein the frame 1 remains fixed in its position. After the device has been displaced in the desired direction in the z- direction, the third locking screw 29 is tightened, ie the contact pressure of the third locking screw 29 on the second guide element 15 'is increased and the set z- direction is fixed. The pressure module is now in a fixed orientation to the frame 1. The two above-described settings of the device in the x- direction and in the z- direction are only examples, further possibilities, the third guide member 17 and the plate 5 with the first guide element 4 are possible to move, in particular settings using micrometer screws. Experiments have shown, however, that the sensitivity of the manual settings described above for the achieved by adjusting the printing module in relation to the frame 1 registration in printing presses are sufficient. Finally, the setting of the device in y- direction is described. For this purpose, the second locking screw 9 is released, which engages in the rest position of the device to the second guide member 15 and fixes the device in the y- direction. Now the movement of the device in the y- direction perpendicular to the frame 1 is enabled. By turning the adjusting screw 10 'engages in a thread of the second guide member 15, the second guide member 15' and with this the second guide member 15 and the third guide member 17 is shifted upward, wherein the second guide elements 15, 15 'to the second Slide guides 22 along and the third guide member 17 is attached to the second guide members 15, 15 'and moves with these. The adjustment screw 10 with the corresponding threaded bore in the second guide element 15 'allows the adjustment of the device in the y direction in the micrometer range. The fastening element 21 is, as mentioned, connected to the third guide element 17, so that the pressure module by the armature 7 on the fastening element 21st is moved up or down in the y direction. After the exact setting of the position in the y- direction in the micrometer range, the second locking screw 9 is tightened in such a way that it engages the second guide member 15 and this and the second guide member 15 'and the third guide member 17 fixed. By fixing the device and the printing module are fixed in the y- direction.
