Abstract

The method involves starting a defined drive position for the resetting. This involves first fixing the new relative positions in the drive wheel train, and then positioning the longitudinal shaft with the coupling being open. The positioning of the longitudinal shaft corresponds to the required drive ratios. This positioning can be achieved by the main drive motor (2) or by a positioning drive (9) for the longitudinal shaft.

Description

Die Erfindung betrifft ein Verfahren zur Antriebsspielbeseitigung in einem Antrieb nach dem Oberbegriff des Anspruches 1, sowie eine Vorrichtung zur Durchführung des Verfahrens nach dem Oberbegriff des Anspruches 10.The invention relates to a method for eliminating drive play in a drive according to the generic term of claim 1, and a device for performing of the method according to the preamble of Claim 10.

In Mehrfarben-Druckmaschinen werden die verschiedenen Druckwerke zur Übertragung von Teilbildern häufig durch eine alle Einzelantriebe verbindende Längswelle angetrieben. Die Druckwerke sind zur Synchronisierung außerdem untereinander mit einem Räderzug verbunden. Da es innerhalb des Räderzuges zu Spiel kommen kann besteht die Gefahr, daß Unregelmäßigkeiten bei der Druckbildübertragung entstehen. So können z.B. Teilbilder beim Aufdrucken nicht exakt übereinander liegen. Um die Probleme aus dem Zahnradspiel des Räderzuges zu beseitigen, ist es bekannt, innerhalb des Antriebes Spielbeseitigungsmaßnahmen zu ergreifen, indem eine Vorspannung auf den Antrieb gebracht wird.In multicolor printing machines, the different Printing units for the transfer of drawing files often by connecting all individual drives Longitudinal shaft driven. The printing units are for synchronization also with one another Wheel train connected. Since it's inside the gear train there may be a risk of irregularities arise during the print image transfer. For example, Drawing files not when printed lie exactly on top of each other. To the problems from the Eliminating the gear train of the gear train is known, within the drive game elimination measures to take by biasing on the drive is brought.

Aus der DE-PS 2 340 263 ist z.B. ein Antrieb für Mehrfarben-Bogenrotationsdruckmaschinen in Reihenanordnung mit mindestens zwei Druckwerken bekannt. Hier ist der Antrieb gelöst durch eine Längswelle und zwei Schneckengetriebe, die die Längswelle mit dem Räderzug der Einzeldruckwerke verbinden. Zur Spielbeseitigung ist die Längswelle aufgeteilt und mit einer axial beweglichen Kupplung verbunden. Diese axialbewegliche Kupplung kann mit Hilfe einer Hydraulik zur Verspannung des Antriebes im Bereich der Schneckengetriebe verstellt werden.From DE-PS 2 340 263 e.g. a drive for Multi-color sheet-fed rotary printing presses arranged in rows known with at least two printing units. Here the drive is solved by a longitudinal shaft and two worm gears that connect the longitudinal shaft with the Connect the wheel train of the individual printing units. To eliminate the game the longitudinal shaft is divided and with a axially movable coupling connected. This axially movable Coupling can be made using a hydraulic system Tensioning the drive in the area of the worm gear be adjusted.

Aus der CH-PS 570 266 ist weiterhin ein Antrieb für eine Mehrfarben-Rotationsbogendruckmaschine mit Reihenbauweise der Druckwerke bekannt. Dieser Antrieb weist ebenfalls eine Längswelle auf, die aufgeteilt ist. Die Längswellenteile sind mit einer Drehstabfeder miteinander verbunden. Ein zusätzlich angeordnetes Getriebe dient zur Vorspannung dieser Drehstabfeder, um Spiel im Antrieb zu beseitigen.From CH-PS 570 266 is still a drive for a multi-color rotary sheet printing machine with Series construction of the printing units known. This Drive also has a longitudinal shaft, which is divided is. The longitudinal shaft parts are with a torsion bar spring connected with each other. An additional arranged gear is used to preload this Torsion bar spring to eliminate play in the drive.

Weiterhin ist aus der DE 2 354 541 ein Antrieb für Mehrfarben-Bogenrotationsdruckmaschinen in Reihenanordnung mit mindestens zwei Druckwerken bekannt. Hier ist eine Längswelle zum Antrieb von Schneckengetrieben für Einzeldruckwerke unter axialer Vorspannung gesetzt, um das Spiel in den Schneckengetrieben zu beseitigen.Furthermore, from DE 2 354 541 a drive for Multi-color sheet-fed rotary printing presses arranged in rows known with at least two printing units. Here is a longitudinal shaft for driving worm gears for single printing units under axial preload set to the game in the worm gears remove.

Schließlich ist aus der DD 258 399 B5 ein Antrieb für Mehrfarbenbogenrotationsdruckmaschinen bekannt. Die Bogenrotationsdruckmaschine ist für Schöndruck oder Schön- und Widerdruck vorgesehen. Der Antrieb weist dazu im Räderzug eine entkoppelbare Zahnradverbindung auf. Parallel zum Räderzug ist eine Längswelle angeordnet. Die Längswelle ist im Bereich des entkoppelbaren Räderzuges mit einer Schaltkupplung versehen, mittels derer sich die Längswelle auftrennen lässt. Die Schaltkupplung ist im Bereich der Längswelle zwischen zwei von der Längswelle in den Räderzug abgehenden Eintrieben angeordnet. Die Eintriebe liegen diesseits und jenseits der Auftrennung des Räderzuges. Die Längswelle ist mittels Zwischenschaltung von Drehstabfedern mit dem durchgehenden Räderzug gekoppelt.Finally, the DD 258 399 B5 is a drive for multi-color sheet-fed rotary printing presses known. The sheet-fed rotary printing press is for Face printing or face and back printing provided. The drive points to this a decouplable gear connection in the gear train. Parallel to the gear train a longitudinal shaft is arranged. The longitudinal shaft is in the area of the decouplable Wheel train with a clutch, by means of which the Can split longitudinal shaft. The clutch is in the area of the longitudinal shaft between two drives coming from the longitudinal shaft into the gear train arranged. The drives are on both sides and beyond the separation of the Gear train. The longitudinal shaft is through the interposition of torsion bar springs coupled with the continuous gear train.

All diese Anordnungen weisen den Nachteil auf, daß sie permanent auf den Antrieb wirken bzw. alle Druckwerke permanent miteinander verbinden. Für die Ausführung einer sogenannten Bogenwendung ist es aber erforderlich, daß je nach Lage der Wendestelle unterschiedlich viele Druckwerke entsprechend dem Bogenformat gegeneinander zu verstellen sind. Dazu ist vorgesehen, daß an einer Stelle des Räderzuges eine auftrennbare Verbindung des Antriebes geschaffen wird. Bei Lösung einer dort angeordneten Kupplung können die Druckwerke vor und hinter der Wendestelle gegeneinander verdreht werden. Durch diese Verstellung verändern sich aber die Spielverhältnisse zwischen den Druckwerksgruppen. Eine durchgehende Verbindung der Antriebsteile mittels einer Längswelle ist mit den bekannten Anordnungen für einen solchen Anwendungsfall nicht möglich.All of these arrangements have the disadvantage of that they act permanently on the drive or all Connect printing units permanently. For the It is execution of a so-called archery turn but required that depending on the location of the turning point different number of printing units according to the Sheet format to be adjusted against each other. To it is provided that at one point of the gear train created a disconnectable connection of the drive becomes. When a clutch arranged there is released can the printing units in front of and behind the turning point be twisted against each other. By this adjustment but the playing conditions change between the printing unit groups. A continuous Connection of the drive parts by means of a longitudinal shaft with the known arrangements for such Use case not possible.

Es ist daher erforderlich, eine Einrichtung zu schaffen, die auf dieses Problem einstellbar ist.It is therefore necessary to create a facility which is adjustable to this problem.

Aufgabe der Erfindung ist es, ein Verfahren mit zugehöriger Vorrichtung nach dem Oberbegriff des Patentanspruchs 1 derart zu verbessern, daß bei Mehrfarben-Bogendruckmaschinen mit wahlweiser Bogenwendung innerhalb des Antriebes beliebige Betriebszustände durch Spielbeseitigung berücksichtigt werden können.The object of the invention is to provide a method associated device according to the preamble of Claim 1 to be improved in such a way that in multi-color sheet-fed printing machines with optional bow turning any within the drive Operating conditions taken into account by eliminating the game can be.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Patentanspruchs 1. Vorteilhaft ist hier, daß an beliebiger Stelle der Maschine eine Wendeeinrichtung eingesetzt werden kann, ohne daß dadurch die Gefahr unterschiedlicher Spielverhältnisse innerhalb des Antriebsstranges entsteht. Das Verfahren zur Beseitigung des Spieles ist automatisch nach jedem Umstellvorgang abrufbar. Außerdem sind die Antriebsverhältnisse an den verschiedenen Abzweiggetrieben der Längswelle immer konstant zu halten. Die Vorrichtung gestaltet sich sehr einfach, da bereits vorhandene Baugruppen verwendet werden und lediglich je Teil der Längswelle eine einzige handelübliche Kupplung benötigt wird.The solution to this problem arises from the characterizing features of claim 1. It is advantageous here that the Machine a turning device can be used can without the danger of different Play conditions arise within the drive train. The process of eliminating the game is can be called up automatically after each changeover. In addition, the drive ratios are different Branch drive of the longitudinal shaft always to keep constant. The device is very designed easy because existing assemblies are used and only one for each part of the longitudinal shaft commercially available coupling is required.

Die Erfindung wird im folgenden anhand von Zeichnungen in einem Ausführungsbeispiel näher beschrieben.The invention is described below with reference to drawings described in more detail in an exemplary embodiment.

In Fig. 1 ist ein Schema einer Bogenrotationsdruckmaschine für den Mehrfarbendruck dargestellt Die Bogenrotationsdruckmaschine weist einen Antriebsräderzug 1 zur Verbindung verschiedener einzelner Druckwerke A-E auf, wobei jeweils an einem Druckzylinder und einer Bogenübergabetrommel Antriebszahnräder vorgesehen sind, die wechselseitig miteinander in Eingriff stehen. Die Bogenrotationsdruckmaschine wird von einem Hauptantriebsmotor 2 über eine Längswelle 3 angetrieben. Von der Längswelle 3 werden über zwei Eintriebe 4, 5 die erforderlichen Antriebsleistungen auf die Antriebszahnräder der Druckzylinder zweier unterschiedlicher Druckwerke B, D abgezweigt. Die Bogenrotationsdruckmaschine ist zur Ausführung eines zweiseitigen Drucks, des sogenannten Schön- und Widerdrucks, geeignet. 1 is a schematic of a sheet-fed rotary printing press shown for multi-color printing Sheet-fed rotary printing press has a drive wheel train 1 to connect different individual Printing units A-E, each on a printing cylinder and a sheet transfer drum drive gears are provided which mutually in with each other Stand by. The sheet-fed rotary printing press will from a main drive motor 2 via a longitudinal shaft 3 driven. The longitudinal shaft 3 are over two Inputs 4, 5 have the required drive powers the drive gears of the printing cylinders of two different ones Printing units B, D branched off. The sheet-fed rotary printing machine is to execute a two-sided printing, the so-called beauty and Back pressure, suitable.

Dazu ist im Antriebsräderzug 1 eine hier nicht näher dargestellte Einrichtung zur Getriebezugtrennung 6 vorgesehen, hier beispielhaft am Druckwerk C, mittels derer die starre Koppelung der Druckwerke B und C untereinander auftrennbar ist. Sie ermöglicht eine Verstellung, derart, daß die Druckwerke A, B vor und C-E hinter der Trennstelle gegeneinander verdrehbar und wieder starr koppelbar sind.There is not one here in the drive wheel train 1 device for gear train separation shown in more detail 6 provided, here for example on the printing unit C, by means of which the rigid coupling of the printing units B and C is separable from one another. It enables an adjustment such that the printing units A, B before and C-E can be rotated against each other behind the separation point and are rigidly connectable again.

In Fig. 2 ist der Antrieb etwas näher dargestellt. Zum Beispiel soll die Einrichtung zum Getriebezugtrennung 6 auf dem Antriebszahnrad 7 angeordnet sein. Sie liegt damit im Bereich der Eintriebe 4, 5 von der Längswelle 3 in den Antriebsräderzug 1. Weiterhin ist die Längswelle 3 zwischen den beiden Eintrieben 4, 5 mittels einer schaltbaren Kupplung 8 auftrennbar. Die Kupplung 8 ist hier als Kegelkupplung dargestellt. Schließlich ist in der Nähe des hinter der Kupplung 8 liegenden Eintriebs 4 ein Positionierantrieb 9 angeordnet, der über ein Getriebe 10 an der Langswelle 3 angreift. Der Positionierantrieb 9 ist für die automatisierte Verstellung der Druckwerke F, G relativ zueinander bei der Umstellung vom Schöndruck in den Schön- und Widerdruck und umgekehrt eingerichtet. Er erlaubt auch die exakte Einstellung der Relativlage der Druckwerke F, G zueinander, da diese Position vom jeweils verarbeiteten Papierformat abhängig ist. Die Umstellung in die jeweils andere Betriebsweise kann aber auch über einen entsprechend steuerbaren Hauptantriebsmotor 2 erfolgen.The drive is shown in more detail in FIG. 2. For example, the device for gear train separation 6 be arranged on the drive gear 7. she thus lies in the area of the drives 4, 5 from the longitudinal shaft 3 in the drive wheel train 1. Furthermore, the Longitudinal shaft 3 between the two drives 4, 5 by means of a switchable clutch 8 separable. The Coupling 8 is shown here as a cone coupling. Finally, is close to the one behind the clutch 8 Input 4 a positioning drive 9 arranged, which engages the longitudinal shaft 3 via a gear 10. The positioning drive 9 is for automated adjustment of the printing units F, G relative to one another at Changeover from face printing to face and back printing and vice versa. He also allows that exact setting of the relative position of the printing units F, G to each other, since this position is processed by the Paper size is dependent. The changeover to each other modes of operation can also be used accordingly controllable main drive motor 2.

Die Funktion der Vorrichtung ist wie folgt:
Zur Verstellung der Bogenrotationsdruckmaschine entweder in die Position zur Produktion mit Bogenwendung oder in die Position zur Produktion im reinen Schöndruck werden sowohl die Einrichtung zur Getriebezugtrennung 6 als auch die Kupplung 8 der Längswelle 3 freigeschaltet. Dann wird mittels des Hauptantriebsmotors 2 oder des Positionierantriebs 9 die vom Papierformat abhängig Verdrehung der Druckwerke F, G zueinander eingestellt. Anschließend können der Antriebsräderzug 1 an der Einrichtung zur Getriebezugtrennung 6 und die Längswelle 3 an der Kupplung 8 wieder starr gekoppelt werden.The function of the device is as follows:
To adjust the sheet-fed rotary printing machine either to the position for production with sheet turning or to the position for production in straight printing, both the device for gear train separation 6 and the clutch 8 of the longitudinal shaft 3 are activated. Then the rotation of the printing units F, G relative to one another is adjusted by means of the main drive motor 2 or the positioning drive 9. Subsequently, the drive wheel train 1 can be rigidly coupled again to the gear train separation device 6 and the longitudinal shaft 3 to the clutch 8.

Damit ist die Relativlage der Druckwerke F, G eingestellt. Zur Sicherstellung des exakten Bogentransports ist nun die Einstellung der Eintriebe 4, 5 auf die Spielverhältnisse des Antriebsräderzugs 1 inclusive der Eintriebe 4, 5 und der Torsion der Längswelle 3 aus den Lastverhältnissen im Druckbetrieb erforderlich.The relative position of the printing units F, G is thus set. To ensure exact sheet transport is now the setting of the drives 4, 5 on the Play ratios of the drive wheel train 1 including the Drives 4, 5 and the torsion of the longitudinal shaft 3 from the Load conditions in printing operation required.

  • 8. automatic drive play compensation with
    • Position the parts of the longitudinal shaft 3 to each other and

    • Die automatische Kompensation des Zahnradspiels im Antrieb erfolgt durch Positionierung der Längswellenteile nach dem Lösen der Kupplung 8 relativ zueinander und ist, abhängig von der Wahl des Antriebs für die Positionierung, in verschiedenen Verfahrensschritten möglich:

  • I. Bei Nutzung des Hauptantriebsmotors 2 und Fixierung des dem Eintrieb gegenüberliegenden Maschinenbereichs
  • a)
  • - Schleichgang vorwärts mit Hauptantriebsmotor 2 bis zum Kuppelwinkel ALPHA
  • - Hauptantriebsmotor 2 anhalten

    • Einkuppeln der Kupplung 8 der Längswelle 3
    • The automatic compensation of the gear play in the drive takes place by positioning the longitudinal shaft parts after releasing the clutch 8 relative to one another and, depending on the choice of the drive for the positioning, is possible in different process steps:
  • I. When using the main drive motor 2 and fixing the machine area opposite the input
  • a)
  • - Slow speed forward with main drive motor 2 up to the ALPHA coupling angle
  • - Stop the main drive motor 2

    • Durch die Koppelung der Längswelle 3 in einer zur Position des Antriebs nach der Umstellung der Betriebsart verschiedenen Lage wird sichergestellt, daß die Spielverhältnisse in den Antriebsteilen an die Erfordernisse des jeweiligen Druckprozesses angepasst sind.By coupling the longitudinal shaft 3 in a Position of the drive after the changeover Operating mode different location ensures that the play in the drive parts to the requirements adapted to the respective printing process are.

    Die Verfahrensweise mit Nutzung des Hauptantriebsmotors 2 hat den Vorteil, daß Belastungen aus der Maschinenbewegung direkt in die Spielverhältnisse übernommen werden. Insbesondere ist es möglich, bei Einkoppelung aus der Bewegung heraus, ein Regelverfahren zu schaffen, das unterschiedliche Antriebslasten berücksichtigt. Dazu kann die Verstellbewegung bei nach Kennlinien definierten unterschiedlichen Drehzahlen ausgeführt werden. Damit sind unterschiedliche Drehmomentverhältnisse und Antriebslastverteilungen auf die verschiedenen Eintriebe 4, 5 simulierbar.The procedure using the main drive motor 2 has the advantage that loads from the Machine movement directly into the playing conditions be taken over. In particular, it is possible to Coupling from the movement, a control procedure to create different drive loads considered. The adjustment movement can help with this different speeds defined according to characteristic curves be carried out. So that are different Torque ratios and drive load distributions can be simulated on the various drives 4, 5.

    Eine pragmatische Lösung wird durch die Nutzung des Positionierantriebs 9 ausgewiesen. In diesem Fall wird eine aufwendige Ausstattung des Hauptantriebsmotors 2 bezüglich seiner Regelgenauigkeit vermieden. Der Positionierantrieb 9 ist per se auf die Ausführung kleiner Winkelschritte ausgelegt und wird für eine zusätzliche Funktion nutzbar gemacht.A pragmatic solution is through use of the positioning drive 9. In this case becomes a complex equipment of the main drive motor 2 avoided with regard to its control accuracy. The positioning drive 9 is per se on the execution designed small angle steps and is for a additional function made usable.

    Es hat sich gezeigt, daß die geforderten Winkel BETA und GAMMA für die erforderliche Antriebsgenauigkeit leicht bestimmbar sind. Beispielsweise wird der Winkel BETA mit 1 Grad Maschinenwinkel die Erfordernisse befriedigen. Mit diesem Verdrehwinkel wird in einem ersten Schritt eine Anlage aller Zahnflanken im Antrieb erreicht. Durch die Auftrennung der Längswelle 3 sind aber vom Antriebszustand im Maschinenbetrieb unterschiedliche Zahnflanken in Anlage, da bei der Positionierung nur ein Teil der Längswelle 3 direkt, der andere aber über den Antriebsräderzug 1 bewegt wird. Die Anlage der Betriebsflanken, dh. der im Druckbetrieb genutzten Zahnflanken, wird daher in der Rückdrehbewegung hergestellt. In besonders vorteilhafter Weise kann nahezu jede gewünschte Drehmomentenverteilung zwischen den Eintrieben durch Positionieren des Antriebs mit unterschiedlichen Werten des Winkels GAMMA gewährleistet werden. Das Rückdrehen bringt die noch "falsch" anliegenden Zahnflanken entsprechend in den geforderten Betriebszustand.It has been shown that the required angle BETA and GAMMA for the required drive accuracy are easy to determine. For example, the BETA angle with 1 degree machine angle the requirements to satisfy. With this angle of rotation is in in a first step, an installation of all tooth flanks in the Drive reached. By separating the longitudinal shaft 3 are from the drive state in machine operation different tooth flanks in the system, because with the Positioning only part of the longitudinal shaft 3 directly, the others but is moved via the drive wheel train 1. The establishment of the operating edges, ie. the one in printing used tooth flanks, is therefore in the reverse rotation manufactured. In a particularly advantageous way can handle almost any desired torque distribution between the drives by positioning the Drive with different values of the angle GAMMA can be guaranteed. Turning back brings the tooth flanks that are still "incorrectly" corresponding in the required operating state.

    Hierzu ist ebenfalls ein Regelverfahren denkbar, bei dem ausgehend von der erwarteten Maschinenbelastung selbsttätig der Winkel GAMMA gewählt wird. Die Maschinenbelastung ist z.B. von der Nutzung einer Mehrfarben-Bogendruckmaschine mit gegebenenfalls vorhandenen Zusatzaggregaten wie Lackiereinrichtungen abhängig, da nicht immer alle Druckwerke A-F genutzt werden. Durch entsprechende Einstellung auf die Anzahl der genutzten Druckwerke A-F und Zusatzaggregate wird der Winkel GAMMA aus einem Kennlinienfeld ausgewählt.A control procedure is also conceivable for this based on the expected machine load the angle GAMMA is selected automatically. The Machine load is e.g. from using one Multi-color sheet printing machine with if necessary existing additional units such as painting equipment dependent, since not all printing units A-F be used. By setting accordingly the number of printing units A-F and additional units used the angle GAMMA is from a characteristic field selected.

    Normalerweise genügt aber eine Definition des Winkels GAMMA für die Betriebsarten Schöndruck und Schön- und Widerdruck, die aber auch für beide Betriebsarten gleich sein kann.Usually a definition of the suffices GAMMA for the straight printing and Nice and reverse printing, but also for both Operating modes can be the same.

    Vom Prinzip her ist es also erforderlich der Kupplung 8 in der Längswelle 3 einen steuerbaren Antrieb (Hauptantriebsmotor 2 oder Positionierantrieb 9) zuzuordnen, derart, daß die beiden Kupplungsteile in beliebiger Richtung in beliebigem Winkel zur Spielbeseitigung verdreht werden können, bevor die Trennung der Kupplung 8 wieder aufgehoben wird. Die dargestellte Form der Bedienung ist als Spezialfall anzusehen.In principle, the clutch is required 8 in the longitudinal shaft 3 a controllable drive (Main drive motor 2 or positioning drive 9), such that the two coupling parts in any Direction at any angle to Game elimination can be twisted before that Separation of the clutch 8 is canceled again. The shown form of operation is a special case to watch.

    Das Verfahren ist entsprechend auch bei Antrieben mit mehr als zwei Eintrieben von einer zu einem Antriebsräderzug parallelen Längswelle aus anwendbar. Die Verfahrensschritte ergeben sich dann sinngemäß. Zu berücksichtigen bleibt nur bei der Schaltfolge die Orientierung innerhalb des Antriebs abhängig davon, wo jeweils die Getriebezugtrennung/-en und die Kupplung/-en in der Längswelle angeordnet sind.The procedure is also the same for drives with more than two drives from one to one Drive gear train parallel longitudinal shaft applicable. The procedural steps are then analogous. Only the switching sequence must be taken into account the orientation within the drive depends of where each the gear train separation / s and Coupling / s are arranged in the longitudinal shaft.
