Description

Die Erfindung betrifft eine Einrichtung zur Einstellung des Schrägregisters in einer Spanneinrichtung zum Einspannen von Druckplatten in einer Offsetdruckmaschine, bei der eine Spannleiste mit Mitteln zum Öffnen und Schließen eines Spalts zum Einschieben und Festspannen der Vorder- oder Hinterkante einer Druckplatte an der Mantelfläche des Plattenzylinders parallel Zylinderachse zur ausgerichtet ist und bei der ein radial zum Plattenzylinder ausgerichteter in den Einschubspalt reichender Zentrierbolzen befestigt ist, dessen Profil mit dem Profil einer Zentriernut in der Einschubkante der Druckplatte korrespondiert.The invention relates to a device for adjusting the inclined register in a clamping device for clamping printing plates in an offset printing press, in which a clamping bar with means for opening and closing a gap for inserting and tightening the front or rear edge of a printing plate on the lateral surface of the plate cylinder parallel to the cylinder axis is aligned and in which a centering bolt, which is aligned radially to the plate cylinder and extends into the insertion gap, is fixed, the profile of which corresponds to the profile of a centering groove in the insertion edge of the pressure plate.

Es ist bekannt, Druckplatten im Plattenzylinder einer Offsetdruckmaschine in Spannleisten einzuspannen. Um eine genau definierte Lage des Druckbilds auf dem bedruckten Papierbogen zu erhalten ist es erforderlich, daß sich das auf der Druckplatte befindliche Druckbild ebenfalls in einer ganz genau definierten Lage befindet. Aufgrund verschiedener Ungenauigkeiten, beispielsweise im Bereich der Montage des Bildes auf der Platte, durch Stanzfehler der Druckplatte oder durch sonstige Fehler in der Druckvorstufe aber auch durch möglicherweise unkorrektes Einspannen der Druckplatte, kommt es immer wieder zu geringfügigen Abweichungen des Druckbildes auf der Druckplatte bezüglich ihrer definierten Lage auf dem Plattenzylinder. Insbesondere im Bereich des Mehrfachdrucks ist eine genaue Bildübereinstimmung der auf den Druckplatten montierten Druckbilder zueinander erforderlich. Um diese Abweichungen des Druckbildes von der definierten Lage auszugleichen, ist es bekannt, Korrektureinrichtungen für die Lage der Druckplatte im Plattenzylinder vorzusehen. Korrekturen können dabei zur seitlichen Verstellung des Druckbildes, zur Umfangsverstellung des Druckbildes und zur Schrägverstellung des Druckbildes erforderlich werden.It is known to clamp printing plates in the plate cylinder of an offset printing machine in clamping bars. In order to obtain a precisely defined position of the printed image on the printed paper sheet, it is necessary that the printed image on the printing plate is also in a very precisely defined position. Due to various inaccuracies, for example in the area of mounting the image on the plate, due to punching errors in the printing plate or due to other errors in the prepress stage, but also due to possibly incorrect clamping of the printing plate, there are always slight deviations of the printed image on the printing plate with respect to its defined one Position on the plate cylinder. Particularly in the area of multiple printing, an exact image match of the printed images mounted on the printing plates is necessary. In order to compensate for these deviations of the printed image from the defined position, it is known to provide correction devices for the position of the printing plate in the plate cylinder. Corrections can be made for the lateral adjustment of the Print image, for circumferential adjustment of the print image and for inclined adjustment of the print image are required.

Zur Schrägverstellung ist es bekannt, die Spannleiste zum Einspannen der Druckplatte nach Einspannen der Druckplatte mit aufwendigen kostenintensiven Maßnahmen komplett gegenüber dem Plattenzylinder schräg zu verstellen.For inclined adjustment, it is known that the clamping bar for clamping the printing plate after clamping the printing plate can be completely inclined with respect to the plate cylinder using complex, cost-intensive measures.

Der Erfindung liegt das Problem zugrunde, eine echte Schrägverstellung der Druckplatte einfach und kostengünstig zu ermöglichen.The invention is based on the problem of making true inclination of the printing plate simple and inexpensive.

Erfindungsgemäß gelöst wird das Problem durch die Ausgestaltung einer Spanneinrichtung zum Einspannen von Druckplatten in einer Offsetdruckmaschine gemäß den Merkmalen von Anspruch 1. Der in Umfangsrichtung verstellbare Anschlag in der Spannleiste ermöglicht eine einfache Schrägverstellung der Druckplatte. Die Druckplatte ist auf einer Seite mit einer vorgestanzten Zentriernut im festen Zentrierbolzen zentriert und kann durch einfache Verstellung des Anschlags, der in der Spannleiste auf die andere Seite der Druckplatte einwirkt somit um den Zentrierbolzen verdreht und somit schräg verstellt werden. Bei manueller Betätigung wird die Spannleiste zunächst geöffnet, dann der Anschlag entsprechend dem in bekannter Weise ermittelten Wert der Abweichung verstellt und nach erneuter Anlage der Platte die Spannleiste wieder geschlossen. Auch ein Verstellen bereits vor Einspannen ist möglich, wenn die Abweichung in bekannter Weise aus dem Druckbild auf der Druckplatte vorab ermittelt wird. Auch ein automatisches Öffnen, Nachmessen, Nachstellen und Schließen ist einfach möglich. Die Schrägverstellung ermöglicht dabei mit geringem Aufwand die korrekte Einstellung der Lage.According to the invention, the problem is solved by the configuration of a clamping device for clamping printing plates in an offset printing machine according to the features of claim 1. The circumferentially adjustable stop in the clamping bar enables the printing plate to be easily inclined. The pressure plate is centered on one side with a pre-punched centering groove in the fixed centering bolt and can be rotated around the centering bolt and thus adjusted at an angle by simply adjusting the stop, which acts on the other side of the pressure plate in the clamping bar. When operated manually, the tensioning bar is first opened, then the stop is adjusted according to the value of the deviation determined in a known manner and the tensioning bar is closed again after the plate has been placed on again. Adjustment before clamping is also possible if the deviation is determined in advance in a known manner from the printed image on the printing plate. Automatic opening, measuring, readjusting and closing is also easily possible. The inclined adjustment enables the correct setting of the position with little effort.

Besonders einfach zu bedienen und zu fertigen ist ein Anschlag gemäß den Merkmalen von Anspruch 3. Durch einfaches Verdrehen des Anschlags um seine Symmetrieachse ist eine zuverlässige Schrägverstellung möglich. Eine erfindungsgemäße Ausbildung gemäß den Merkmalen der Ansprüche 4 und 5 begünstigt zusätzlich eine sichere zuverlässige Bedienung der Schrägverstellung ohne größeren Aufwand. Die Ausbildung gemäß den Merkmalen der Ansprüche 6 und 7 stellen dabei besonders bevorzugte Ausgestaltungsformen dar. Eine besonders einfache, kostengünstige Spanneinrichtung ist durch die Ausführungsformen gemäß den Merkmalen der Ansprüche 8 bis 10 ermöglicht.The inventive design is particularly simple and inexpensive according to the feature of claim 2. Additional Adjustments can be omitted. A stop according to the features of claim 3 is particularly easy to use and manufacture. Reliable inclination adjustment is possible by simply rotating the stop about its axis of symmetry. An inventive design according to the features of claims 4 and 5 also favors safe reliable operation of the inclined adjustment without great effort. The design according to the features of claims 6 and 7 represent particularly preferred embodiments. A particularly simple, inexpensive tensioning device is made possible by the embodiments according to the features of claims 8 to 10.

Dieses kann dabei automatisch gesteuert fest oder lösbar mit dem Anschlag gekuppelt sein.The inventive design according to the features of claim 11 additionally enables simple operability with the aid of a tool. This can be automatically or permanently coupled or detachably coupled to the stop.

Die erfindungsgemäße Ausbildung gemäß dem Merkmal von Anspruch 12 begünstigt zusätzlich die genaue Einstellung des Anschlags und somit die genaue Schrägverstellung der Platte.The inventive design according to the feature of claim 12 also favors the precise setting of the stop and thus the exact inclination of the plate.

Die erfindungsgemäße Ausbildung gemäß dem Merkmal von Anspruch 13 und 14 stellen bevorzugte einfache, zuverlässige Spanneinrichtungen zur Schrägverstellung dar.The inventive design according to the feature of claims 13 and 14 represent preferred simple, reliable clamping devices for inclined adjustment.

Die Fig. 1 bis 3 zeigen ein erfindungsgemäßes Ausführungsbeispiel, bei dem die Vorderkante einer Druckplatte 1 zwischen einem festen Spannleistenteil 6 und einem entsprechend der Pfeildarstellung von Fig. 2 zum Einspannen und Lösen verstellbaren Spannleistenteil 5 eines Plattenzylinders 4 einer Offsetdruckmaschine bekannter Bauart eingespannt ist. Die Platte 1 ist mit einer halbkreisförmigen ausgestanzten Zentriernut an dem zwischen festem Spannleistenteil 6 und verschiebbarem Spannleistenteil 5 radial zum Plattenzylinder befestigten Fixierbolzen 2 an der einen Seite der Druckplatte drehbar fixiert. An der anderen Seite ist die Druckplatte mit einer Anlegekante einer vorgestanzten Anlegenut an die Anschlagsfläche 7 einer Anschlagsschraube 3 angelegt. Die Anschlagsschraube 3 ist in einer Durchgangsbohrung im festen Spannleistenteil 6 so eingeschraubt, daß sie mit ihrer am Schraubenende vorgesehenen Anschlagsfläche 7 in eine zylindrische Ausnehmung 22 zwischen festem Spannteil 6 und verstellbarem Spannteil 5 eingreift. Auf der anderen dem Platteneinschub entgegengerichteten Seite des festen Spannleistenteils 6 ist am Umfang des Kopfes 9 der Schraube 3 eine zylindrische Skala 10 befestigt. Zwischen Schraubenkopf 9 und festem Spannteil 6 wirkt eine vorspannende Feder 8. Der Schraubenkopf 9 ist mit einer Innenprofilierung 11 für den Eingriff mit Hilfe eines Werkzeugs ausgestattet. Zum Ausspannen der Platte wird das verschiebbare Spannleistenteil 5 entsprechend der Darstellung von Fig. 2 nach unten verstellt, so daß der Spalt zwischen festem und verstellbarem Spannteil 5, 6 sich vergrößert und die Druckplatte 1 herausgezogen werden kann. Vor Einspannen einer Platte wird in bekannter Weise die Lage des Druckbilds auf der Druckplatte vermessen und somit die Abweichung von der gewünschten Soll-Lage ermittelt. Entsprechend der Abweichung in der Schräglage wird die Anschlagsschraube 3 mit Hilfe der Feinskalierung 10 so eingestellt, daß die Abweichung der Schräglage eliminiert werden kann. Hierzu ist es denkbar beispielsweise am Festspannteil zur besseren Einstellbarkeit eine Gegenmarkierung vorzusehen. Nach Einstellung der Position der Anschlagschraube 3 wird die Platte 1 in den Spalt zwischen festem und verschiebbarem Spannteil 5, 6 eingeschoben, so daß die Druckplatte 1 am festen Zentrierbolzen 2 zentriert und an ihrer anderen Seite an der Anschlagsfläche 7 der Anschlagsschraube 3 anliegt. Anschließend wird das verstellbare Spannteil 5 entsprechend der Darstellung von Fig. 2 nach oben verschoben, bis die Druckplatte 1 eingespannt ist. Zur Verstellwegsbegrenzung der Anschlagsschraube 3 ist im Plattenzylinder 4 eine Anschlagsfläche 23 vorgesehen. Die Vorspannung der Feder 8 verhindert ein unfreiwilliges Lösen der Anschlagsschraube 3. Die Anschlagsschraube 3 ist mit kleiner Gewindesteigung versehen zur feinfühligen Einstellmöglichkeit.1 to 3 show an exemplary embodiment according to the invention, in which the front edge of a printing plate 1 is clamped between a fixed clamping strip part 6 and a clamping strip part 5 of a plate cylinder 4, which is adjustable for clamping and releasing, of a plate cylinder 4 of a known type. The plate 1 is rotatably fixed to the one side of the pressure plate with a semicircular punched centering groove on the fixing bolt 2, which is fixed radially to the plate cylinder, between the fixed clamping strip part 6 and the displaceable clamping strip part 5. On the other side, the pressure plate is applied to the stop surface 7 of a stop screw 3 with a contact edge of a pre-punched contact groove. The stop screw 3 is screwed into a through hole in the fixed clamping strip part 6 so that it engages with its stop surface 7 provided at the screw end in a cylindrical recess 22 between the fixed clamping part 6 and the adjustable clamping part 5. On the other, the panel insert opposite side of the fixed clamping strip part 6, a cylindrical scale 10 is attached to the circumference of the head 9 of the screw 3. A prestressing spring 8 acts between the screw head 9 and the fixed clamping part 6. The screw head 9 is equipped with an internal profile 11 for engagement with the aid of a tool. For unclamping the plate, the displaceable clamping strip part 5 is adjusted downwards as shown in FIG. 2, so that the gap between the fixed and adjustable clamping part 5, 6 increases and the pressure plate 1 can be pulled out. Before clamping a plate, the position of the printed image on the printing plate is measured in a known manner and the deviation from the desired target position is thus determined. According to the deviation in the inclined position, the stop screw 3 is adjusted with the help of the fine scale 10 so that the deviation in the inclined position can be eliminated. For this purpose, it is conceivable, for example, to provide a counter marking on the clamping part for better adjustability. After adjusting the position of the stop screw 3, the plate 1 is inserted into the gap between the fixed and displaceable clamping part 5, 6, so that the pressure plate 1 is centered on the fixed centering pin 2 and bears on its other side against the stop surface 7 of the stop screw 3. The adjustable clamping part 5 is then moved upwards in accordance with the illustration in FIG. 2 until the pressure plate 1 is clamped. A stop surface 23 is provided in the plate cylinder 4 to limit the adjustment path of the stop screw 3. The pre-tensioning of the spring 8 prevents the stop screw 3 from being loosened involuntarily. The stop screw 3 is provided with a small thread pitch for sensitive adjustment.

In den Fig. 4 und 5 ist ein weiteres Ausführungsbeispiel der Erfindung dargestellt. Dabei ist senkrecht zur Einschubrichtung der Druckplatte 1 ein Drehbolzen 14 durch eine Durchgangsbohrung im festen Spannteil 13 geführt. Im Bereich des unteren Spannteils ist eine Ausnehmung 24 eingebracht, in die der Drehbolzen 14 mit seinem unteren Ende reicht. Auf dem unteren Ende des Drehbolzens 14 ist mit Hilfe eines Stiftes 16 ein Zylinderbolzen 15 exzentrisch befestigt. Zwischen Kopf 25 des Drehbolzens 14 und dem festen Spannleistenteil 13 wirkt eine Tellerfeder 26, die den Drehbolzen 14 soweit nach oben drückt, daß der Zylinderbolzen 15 mit seiner oberen Deckfläche in Berührkontakt mit dem festen Spannleistenteil 13 gerät. Die Spannung ist dabei so gewählt, daß der Drehbolzen 14 selbsthemmend verstellt werden kann. Die Druckplatte 1 wird zum Einspannen in den geöffneten Spalt zwischen festem und verschiebbaren Spannleisten 13, 12 so eingeschoben, daß sie mit ihrer vorgestanzten Zentriernut am Zentrierbolzen 2 gemäß der Darstellung von Fig. 1 und mit ihrer anderen vorgestanzten Nut an der Umfangsfläche des Zylinderbolzens 15 anliegt. Durch Verdrehen des Drehbolzens 14 wird der exzentrische Zylinderbolzen um die Achse des Drehbolzens 14 so verdreht, daß eine Anschlagsfläche des Zylinderbolzens 15 für die Druckplatte 1 ihre Position in Einschubrichtung verändert. Somit kann eine genaue Schrägverstellung vorgenommen werden. Zur verbesserten Schrägverstellung ist auf dem Kopf des Drehbolzens 14 eine Skala 17 angebracht.4 and 5 another embodiment of the invention is shown. A pivot pin 14 is perpendicular to the direction of insertion of the pressure plate 1 a through hole in the fixed clamping part 13 out. In the area of the lower clamping part, a recess 24 is made, into which the pivot pin 14 extends with its lower end. On the lower end of the pivot pin 14, a cylinder pin 15 is eccentrically fastened with the aid of a pin 16. Between the head 25 of the pivot pin 14 and the fixed clamping strip part 13, a plate spring 26 acts, which presses the pivot pin 14 upwards to such an extent that the cylinder bolt 15 comes into contact with the fixed clamping strip part 13 with its upper cover surface. The voltage is chosen so that the pivot pin 14 can be adjusted self-locking. The pressure plate 1 is inserted for clamping in the open gap between fixed and displaceable clamping bars 13, 12 so that it rests with its pre-punched centering groove on the centering pin 2 as shown in FIG. 1 and with its other pre-punched groove on the circumferential surface of the cylinder pin 15 . By turning the pivot pin 14, the eccentric cylinder pin is rotated about the axis of the pivot pin 14 so that a stop surface of the cylinder pin 15 for the pressure plate 1 changes its position in the direction of insertion. This enables an exact incline adjustment. A scale 17 is attached to the head of the pivot pin 14 for improved inclination adjustment.

Fig. 6 zeigt ein weiteres Ausführungsbeispiel der Erfindung, bei dem anstelle der Anschlagsschraube 3 des Ausführungsbeispiels der Fig. 1 bis 3 ein Zylinderbolzen 18 mit als Axialkurve ausgebildeter Umfangsnut 21 in einer Durchgangsbohrung des festen Spannleistenteils 6 beweglich gelagert ist. Im festen Spannleistenteil 6 ist ein Führungsstift 20 befestigt, der in die Axialkurvennut 21 eingreift. Durch Verdrehen des Kopfes 19 kann die Anschlagsfläche 7 des Zylinderbolzens 18 aufgrund der Bewegungsumlenkung durch Führungsstift 20 und Axialkurvennut 21 axial verschoben werden. Die Axialkurvennutsteigung ist klein gewählt.6 shows a further exemplary embodiment of the invention, in which, instead of the stop screw 3 of the exemplary embodiment in FIGS. 1 to 3, a cylinder bolt 18 with a circumferential groove 21 designed as an axial curve is movably mounted in a through bore in the fixed clamping strip part 6. A guide pin 20, which engages in the axial cam groove 21, is fastened in the fixed clamping strip part 6. By turning the head 19, the stop surface 7 of the cylinder pin 18 due to the movement deflection by the guide pin 20 and Axialkurvenennut 21 are axially displaced. The axial curve groove pitch is chosen to be small.

In Fig. 2 ist in gestrichelter Darstellung die Anschlagsschraube 3 in einer verstellten Position dargestellt.2, the stop screw 3 is shown in an adjusted position in a broken line.

Es ist sowohl denkbar die Spannleiste 5 als auch die Anschlagsschraube 3, den Anschlagsstift 18 oder den Drehbolzen 14 automatisch zu verstellen. Beispielsweise ist es denkbar, den Drehbolzen 14 automatisch von unten durch die verstellbare Spannleiste 12 hindurch zu verstellen.It is conceivable to automatically adjust the clamping bar 5 as well as the stop screw 3, the stop pin 18 or the pivot pin 14. For example, it is conceivable to automatically adjust the pivot pin 14 from below through the adjustable clamping bar 12.
