Definitions
- the invention relates to a device for circumferential register adjustment in a sheet-fed rotary printing press, which has generic features according to the preamble of claim 1.
- a plate cylinder and a rubber cylinder are adjusted in their phase position. This adjustment thus causes a relative movement between the printing plate of the plate cylinder and the sheet in or against the sheet travel direction.
- differential gears for example planetary gears, or axially displaceable gearwheels with helical teeth are known in order to enable the adjustment while the machine is running, but only in a relatively small area.
- gear drives with at least two intermediate gears are known in particular, which can be moved together with their bearings and thus enable a circumferential register adjustment.
- the storage of the intermediate gears is correspondingly unstable in such designs.
- a circumferential register setting can also be made, if necessary, by the adjustment of the front marks if the paper run makes this possible.
- the cheapest and most common adjustment device acts via gear wheels that can be rotated in their phase position relative to the cylinder, which are released for adjustment and locked again after the adjustment Need to become.
- Such devices for circumferential register adjustment can only be operated when the machine is at a standstill. Readjustments therefore require frequent stopping and restarting of the machine, which requires a relatively large amount of time and a lot of waste.
- the invention solves this problem by features according to the characterizing part of claim 1 in conjunction with the aforementioned generic features.
- the circumferential register adjustment consists partly of the pivoting movement of the plate cylinder and additionally of a rotation by the drive gear in the same direction. This twist results from the meshing of the idler gear with the pressure cylinder. With a very small swivel movement, a circumferential register adjustment can be carried out to a sufficient extent, for example in a range of approximately 5 mm.
- the main advantage of training with the features of the invention is that the pivoting of the frame for the purpose of adjusting the circumferential register can take place while the machine is running, so that the machine does not have to be stopped for adjusting the circumferential register.
- the features of the invention are advantageously used in a sheet-fed rotary printing press with a main printing unit and a satellite printing unit which has plate cylinders driven by an intermediate wheel from the printing cylinder of the master cylinder.
- the satellite printing unit is arranged in the machine frame so as to be pivotable about an axis which, in accordance with the features of claim 1, at the intersection of a straight connecting line through the Axis of the plate cylinder in the satellite printing unit and through the axis of the rubber cylinder in the main printing unit and a straight connecting line through the axis of the intermediate gear for driving the plate cylinder in the satellite printing unit and the axis of the printing cylinder in the main printing unit.
- the frame of the satellite printing unit is mounted on a swivel axis which lies at the intersection of the axes mentioned, and is also supported in a horizontally movable manner, but this support is height-adjustable in order to carry out the swivel movement mentioned.
- a spindle drive, an eccentric or the like is suitable as the simplest machine element for achieving such a height adjustment, but other, in particular motorized, means can also be provided for this height adjustment.
- the device for adjusting the circumferential register is designed to adjust the pressure between the plate cylinder of the satellite printing unit and the rubber cylinder of the main printing unit when it is designed on a satellite printing unit.
- the fulcrum of the frame of the satellite printing unit is slidably arranged on the bisector of the angle between the two straight connecting lines, as defined above. This shift can also take place during machine operation.
- the idler wheel rotates slightly and rotates the plate cylinder of the satellite printing unit counterclockwise. A point on the lateral surface of the plate cylinder moves clockwise during this displacement relative to the rubber cylinder. The resulting twists are equal and thus cancel each other out.
- FIGS. 1 and 2 only the plate cylinder 1, the blanket cylinder 2 and the printing cylinder 3 of a printing unit are shown.
- the mechanically interlocking drive elements of these cylinders 1, 2 and 3 of the printing unit are not shown in the drawing for the sake of a better overview.
- the plate cylinder 4 of the satellite printing unit is mounted in a frame 5, frame or the like, and is driven by an intermediate wheel 6, the toothing of which engages on the one hand in a toothing on the printing cylinder 3 and on the other hand in a toothing on the plate cylinder 4 of the satellite printing unit.
- This intermediate wheel 6 is also rotatably mounted in the frame 5.
- the frame 5 is in turn pivotable about an axis 7, for example about a bolt, which lies at the intersection of straight connecting lines 8 and 9.
- the connecting line 8 runs through the axis 10 of the plate cylinder 4 of the satellite printing unit and through the axis 11 of the blanket cylinder, while the connecting line 9 through the axis 12 of the idler gear and through the axis 13 of the Printing cylinder is placed.
- the frame 5 is also supported on a height-adjustable abutment 14 which, in the case of the example, is designed as a rotatable eccentric 14 in machine-fixed mounting. By rotating the eccentric in one or in the opposite direction, a pivoting movement of the frame about the pivot axis 7 can be achieved in order to carry out a circumferential register adjustment of the plate cylinder 4 with respect to the rubber cylinder 2.
- the pivot bearing of the frame 5 with the axis 7 is linearly adjustable, this movement taking place on the bisector 15 of the angle between the two straight connecting lines 8 and 9.
- This configuration enables the setting of the pressure between the plate cylinder 4 and the blanket cylinder 2, already explained above, in which a mutual cancellation of the influences of this adjustment movement on the circumferential register adjustment is achieved.
- the slight rotational movement of the intermediate wheel 6 resulting from a displacement of the frame 5 on the bisector 15 leads to a rotational movement of the plate cylinder 4, but a point on the lateral surface of the plate cylinder 4 migrates in the opposite direction during this displacement relative to the rubber cylinder, so that both movements cancel each other out.

Description
Die Erfindung betrifft eine Vorrichtung zur Umfangsregisterverstellung in einer Bogenrotationsdruckmaschine, welche Gattungsmerkmale nach dem Oberbegriff des Patentanspruches 1 aufweist.The invention relates to a device for circumferential register adjustment in a sheet-fed rotary printing press, which has generic features according to the preamble of claim 1.
Durch die Verstellung des Umfangsregisters werden ein Plattenzylinder und ein Gummizylinder in ihrer Phasenlage verstellt. Diese Verstellung bewirkt somit eine Relativbewegung zwischen der Druckplatte des Plattenzylinders und dem Bogen in oder entgegen der Bogenlaufrichtung.By adjusting the circumferential register, a plate cylinder and a rubber cylinder are adjusted in their phase position. This adjustment thus causes a relative movement between the printing plate of the plate cylinder and the sheet in or against the sheet travel direction.
Bekannt sind zu diesem Zweck kostenaufwendige Differenzialgetriebe, zum Beispiel Planetenradgetriebe, oder axial verschiebbare Zahnräder mit Schrägverzahnung, um die Verstellung bei laufender Maschine, jedoch nur in einem relativ kleinen Bereich, zu ermöglichen.For this purpose, costly differential gears, for example planetary gears, or axially displaceable gearwheels with helical teeth are known in order to enable the adjustment while the machine is running, but only in a relatively small area.
Bei kleineren Maschinen sind vor allem Zahnradantriebe mit wenigstens zwei Zwischenrädern bekannt, die zusammen mit ihrer Lagerung verschiebbar sind, und somit eine Umfangsregisterverstellung ermöglichen. Die Lagerung der Zwischenzahnräder ist bei solchen Ausführungen entsprechend instabil. Auch durch die Verstellung der Vordermarken kann gegebenenfalls eine Umfangsregistereinstellung erfolgen, wenn der Papierlauf dies ermöglicht. Die kostengünstigste und gebräuchlichste Verstelleinrichtung wirkt über in ihrer Phasenlage zum Zylinder verdrehbare Zahnräder, die zur Verstellung gelöst und nach der Verstellung wieder verriegelt werden müssen. Solche Vorrichtungen zur Umfangsregisterverstellung sind nur im Stillstand der Maschine bedienbar. Nachregulierungen erfordern somit entsprechend häufiges Anhalten und Wiederanfahren der Maschine, wozu ein relativ großer Zeitaufwand erforderlich ist und wobei viel Makulatur anfällt.In the case of smaller machines, gear drives with at least two intermediate gears are known in particular, which can be moved together with their bearings and thus enable a circumferential register adjustment. The storage of the intermediate gears is correspondingly unstable in such designs. A circumferential register setting can also be made, if necessary, by the adjustment of the front marks if the paper run makes this possible. The cheapest and most common adjustment device acts via gear wheels that can be rotated in their phase position relative to the cylinder, which are released for adjustment and locked again after the adjustment Need to become. Such devices for circumferential register adjustment can only be operated when the machine is at a standstill. Readjustments therefore require frequent stopping and restarting of the machine, which requires a relatively large amount of time and a lot of waste.
Die vorstehenden Angaben zum Stande der Technik entsprechen der praktischen Ausführung marktgängiger Maschinen.The above information on the state of the art corresponds to the practical design of machines which are commercially available.
Besonders problematisch ist die Gestaltung einer Umfangsregisterverstellung bei Druckwerken für den Eindruck einer zusätzlichen Farbe, sogenannten Satellitendruckwerken, die demontierbar oder schwenkbar am Gestell einer Bogenrotationsdruckmaschine befestigt sind und lediglich bei Bedarf in eine Betriebsposition gebracht werden. Bei Satellitendruckwerken tragen die Bauteile zur Umfangsregisterverstellung erheblich zur Vergrößerung des Gewichts eines solchen Druckwerkes bei, was unerwünscht ist, und erhöhen auch dadurch die Instabilität.The design of a circumferential register adjustment in printing units is particularly problematic for the impression of an additional color, so-called satellite printing units, which are detachably or pivotably attached to the frame of a sheet-fed rotary printing press and are only brought into an operating position when required. In the case of satellite printing units, the components for adjusting the circumferential register make a considerable contribution to increasing the weight of such a printing unit, which is undesirable, and thereby also increase the instability.
Es ist Aufgabe der Erfindung, besonders einfache und stabile Mittel zur Umfangsregisterverstellung mit hoher Präzision zu schaffen, die eine Umfangsregisterverstellung während des Maschinenlaufs ermöglichen.It is an object of the invention to provide particularly simple and stable means for circumferential register adjustment with high precision, which allow circumferential register adjustment while the machine is running.
Die Erfindung löst diese Aufgabe durch Merkmale nach dem Kennzeichen des Patentanspruches 1 in Verbindung mit den zuvor erwähnten Gattungsmerkmalen.The invention solves this problem by features according to the characterizing part of claim 1 in conjunction with the aforementioned generic features.
Durch eine Schwenkbewegung des Plattenzylinders und des Zwischenzahnrades um eine Achse, die im Schnittpunkt der geraden Verbindungslinie durch die Achsen des Plattenzylinders und des Gummizylinders einerseits sowie des Zwischenrades und des Druckzylinders andererseits liegt, wird eine Relativbewegung der Plattenzylindermantelfläche zur Gummizylindermantelfläche erzeugt, wobei eine Abwälzbewegung der beiden Zylinder aufeinander durch den Zahneingriff zwischen dem Zwischenrad und dem Plattenzylinder verhindert wird. Dabei erfolgt eine weitestgehend minimierte Veränderung der Pressung zwischen dem Gummizylinder und dem Plattenzylinder, wenn von der Stellung mit maximaler Pressung aus eine Verschwenkung im Uhrzeigersinn oder gegen den Uhrzeigersinn erfolgt. Die Verringerung der Pressung ist dabei so geringfügig, daß sie vernachlässigt werden kann.By a pivoting movement of the plate cylinder and the intermediate gear around an axis which lies at the intersection of the straight connecting line through the axes of the plate cylinder and the rubber cylinder on the one hand and the intermediate wheel and the pressure cylinder on the other generates a relative movement of the plate cylinder jacket surface to the rubber cylinder jacket surface, wherein a rolling movement of the two cylinders on one another is prevented by the tooth engagement between the idler gear and the plate cylinder. The pressure between the blanket cylinder and the plate cylinder is minimized as far as possible if the position is swiveled clockwise or counterclockwise from the position with maximum pressure. The reduction in pressure is so slight that it can be neglected.
Die Umfangsregisterverstellung setzt sich dabei zum einen Teil aus der Schwenkbewegung des Plattenzylinders und zusätzlich aus einer Verdrehung durch das Antriebszahnrad in gleicher Richtung zusammen. Diese Verdrehung resultiert aus dem Zahneingriff des Zwischenrades mit dem Druckzylinder. Durch eine sehr kleine Schwenkbewegung kann somit eine Umfangsregisterverstellung in ausreichendem Maße, zum Beispiel in einem Bereich von etwa 5 mm, durchgeführt werden.The circumferential register adjustment consists partly of the pivoting movement of the plate cylinder and additionally of a rotation by the drive gear in the same direction. This twist results from the meshing of the idler gear with the pressure cylinder. With a very small swivel movement, a circumferential register adjustment can be carried out to a sufficient extent, for example in a range of approximately 5 mm.
Der wesentliche Vorteil einer Ausbildung mit den Erfindungsmerkmalen besteht darin, daß die Verschwenkung des Rahmens zum Zwecke der Umfangsregisterverstellung während des Maschinenlaufes erfolgen kann, so daß die Maschine für eine Umfangsregisterjustierung nicht angehalten zu werden braucht.The main advantage of training with the features of the invention is that the pivoting of the frame for the purpose of adjusting the circumferential register can take place while the machine is running, so that the machine does not have to be stopped for adjusting the circumferential register.
Vorteilhafte Anwendung finden die Erfindungsmerkmale bei einer Bogenrotationsdruckmaschine mit einem Hauptdruckwerk und einem Satellitendruckwerk, welches durch ein Zwischenrad vom Druckzylinder des Hauptzylinders angetriebenen Plattenzylinder aufweist. Bei einer solchen Maschinenausbildung ist das Satellitendruckwerk in dem Maschinengestell um eine Achse schwenkbar angeordnet, die in Übereinstimmung mit den Merkmalen nach dem Patentanspruch 1 im Schnittpunkt einer geraden Verbindungslinie durch die Achse des Plattenzylinders im Satellitendruckwerk und durch die Achse des Gummizylinders im Hauptdruckwerk und einer geraden Verbindungslinie durch die Achse des Zwischenzahnrades für den Antrieb des Plattenzylinders im Satellitendruckwerk und der Achse des Druckzylinders im Hauptdruckwerk liegt. Zur Realisierung der Erfindungsmerkmale wird der Rahmen des Satellitendruckwerkes auf einer Schwenkachse gelagert, die im Schnittpunkt der genannten Achsen liegt, und außerdem horizontal gleitend beweglich abgestützt, wobei diese Abstützung jedoch höhenverstellbar ist, um die erwähnte Schwenkbewegung durchzuführen. Als einfachstes Maschinenelement zur Erreichung einer solchen Höhenverstellung ist ein Spindeltrieb, ein Exzenter oder dergleichen, geeignet, jedoch können auch andere, insbesondere motorische Mittel für diese Höhenverstellung vorgesehen sein.The features of the invention are advantageously used in a sheet-fed rotary printing press with a main printing unit and a satellite printing unit which has plate cylinders driven by an intermediate wheel from the printing cylinder of the master cylinder. In such a machine design, the satellite printing unit is arranged in the machine frame so as to be pivotable about an axis which, in accordance with the features of claim 1, at the intersection of a straight connecting line through the Axis of the plate cylinder in the satellite printing unit and through the axis of the rubber cylinder in the main printing unit and a straight connecting line through the axis of the intermediate gear for driving the plate cylinder in the satellite printing unit and the axis of the printing cylinder in the main printing unit. To implement the features of the invention, the frame of the satellite printing unit is mounted on a swivel axis which lies at the intersection of the axes mentioned, and is also supported in a horizontally movable manner, but this support is height-adjustable in order to carry out the swivel movement mentioned. A spindle drive, an eccentric or the like is suitable as the simplest machine element for achieving such a height adjustment, but other, in particular motorized, means can also be provided for this height adjustment.
Nach einem weiteren Erfindungsgedanken ist die Vorrichtung zur Umfangsregisterverstellung bei einer Ausbildung an einem Satellitendruckwerk gleichzeitig zur Einstellung der Pressung zwischen dem Plattenzylinder des Satellitendruckwerkes und dem Gummizylinder des Hauptdruckwerkes ausgebildet. Zur Erreichung dieses Zieles ist der Drehpunkt des Rahmens des Satellitendruckwerkes auf der Halbierenden des Winkels zwischen den beiden geraden Verbindungslinien, wie sie weiter oben definiert sind, verschiebbar angeordnet. Auch diese Verschiebung kann während des Maschinenlaufes erfolgen.According to a further idea of the invention, the device for adjusting the circumferential register is designed to adjust the pressure between the plate cylinder of the satellite printing unit and the rubber cylinder of the main printing unit when it is designed on a satellite printing unit. To achieve this goal, the fulcrum of the frame of the satellite printing unit is slidably arranged on the bisector of the angle between the two straight connecting lines, as defined above. This shift can also take place during machine operation.
Bei der Verschiebung des Schwenklagers auf der Winkelhalbierenden, zum Beispiel zur Verringerung der Pressung, führt das Zwischenrad eine geringfügige Verdrehung aus und dreht dabei den Plattenzylinder des Satellitendruckwerkes im Gegenuhrzeigersinn. Ein Punkt auf der Mantelfläche des Plattenzylinders wandert bei dieser Verschiebung relativ zum Gummizylinder im Uhrzeigersinn. Die daraus resultierenden Verdrehungen sind gleich groß und heben sich somit gegenseitig auf.When the pivot bearing is moved on the bisector of the angle, for example to reduce the pressure, the idler wheel rotates slightly and rotates the plate cylinder of the satellite printing unit counterclockwise. A point on the lateral surface of the plate cylinder moves clockwise during this displacement relative to the rubber cylinder. The resulting twists are equal and thus cancel each other out.

Bei der sehr vereinfachten Darstellung in den Figuren 1 und 2 sind lediglich der Plattenzylinder 1, der Gummizylinder 2 und der Druckzylinder 3 eines Druckwerkes dargestellt. Die mechanisch ineinandergreifenden Antriebsglieder dieser Zylinder 1, 2 und 3 des Druckwerkes sind auf der Zeichnung aus Gründen der besseren Übersicht nicht dargestellt. Der Plattenzylinder 4 des Satellitendruckwerkes ist in einem Rahmen 5, Gestell oder dergleichen, gelagert und wird durch ein Zwischenrad 6 angetrieben, dessen Verzahnung einerseits in eine Verzahnung am Druckzylinder 3 und andererseits in eine Verzahnung am Plattenzylinder 4 des Satellitendruckwerkes eingreift. Auch dieses Zwischenrad 6 ist in dem Rahmen 5 drehbar gelagert. Der Rahmen 5 ist seinerseits um eine Achse 7, zum Beispiel um einen Bolzen, schwenkbar angeordnet, die im Schnittpunkt gerader Verbindungslinien 8 und 9 liegt. Die Verbindungslinie 8 verläuft durch die Achse 10 des Plattenzylinders 4 des Satellitendruckwerkes und durch die Achse 11 des Gummizylinders, während die Verbindungslinie 9 durch die Achse 12 des Zwischenrades und durch die Achse 13 des Druckzylinders gelegt ist. Der Rahmen 5 ist außerdem auf einem höhenverstellbaren Widerlager 14 abgestützt, welches im Falle des Beispieles als ein verdrehbarer Exzenter 14 in maschinenfester Lagerung ausgebildet ist. Durch Verdrehung des Exzenters in der einen oder in der entgegengesetzten Richtung kann eine Schwenkbewegung des Rahmens um die Schwenkachse 7 erreicht werden, um eine Umfangsregisterverstellung des Plattenzylinders 4 gegenüber dem Gummizylinder 2 durchzuführen.In the very simplified representation in FIGS. 1 and 2, only the plate cylinder 1, the
Nach dem Ausführungsbeispiel der Figur 2 ist das Schwenklager des Rahmens 5 mit der Achse 7 linear verstellbar, wobei diese Bewegung auf der Winkelhalbierenden 15 des Winkels zwischen den beiden geraden Verbindungslinien 8 und 9 erfolgt. Diese Ausbildung ermöglicht die weiter oben bereits erläuterte Einstellung der Pressung zwischen dem Plattenzylinder 4 und dem Gummizylinder 2, bei der eine gegenseitige Aufhebung der Einflüsse dieser Einstellbewegung auf die Umfangsregisterverstellung erreicht wird. Die bei einer Verschiebung des Rahmens 5 auf der Winkelhalbierenden 15 entstehende geringfügige Drehbewegung des Zwischenrades 6 führt zwar zu einer Drehbewegung des Plattenzylinders 4, jedoch wandert ein Punkt auf der Mantelfläche des Plattenzylinders 4 bei dieser Verschiebung relativ zum Gummizylinder in entgegengesetzter Richtung, so daß beide Bewegungen sich aufheben.According to the embodiment of Figure 2, the pivot bearing of the
