Definitions
- the invention relates to a device for damping mechanical vibrations of printing presses.
- the drive train of a printing press with the parts coupled to it is a system whose dynamics are determined by spring constants, moments of inertia, etc.
- the rotating parts of this drive train can be excited to vibrate by the following influences.
- Recurring load torque fluctuations are to be counted among the angle-dependent, i.e. synchronous vibrations, such as those caused by cam gears or by errors in single or n-speed gearwheels.
- Vibrations that do not recur periodically with one revolution can be generated, for example, by periodic excitations that deviate from the rotational frequency. They occur, for example, due to belts, lifter knocks, or errors in half-speed gears. Even non-periodic noise processes, such as color splitting or the influence of the paper print, lead to asynchronous vibrations. Furthermore, vibrations in the system can be caused by parameter fluctuations that have a low rate of change compared to sheet travel (for example, oil temperature fluctuations that influence the basic friction).
- the invention is therefore based on the object of specifying a device and a method for damping mechanical vibrations of printing presses in order to improve the print quality.
- At least one actuator assigned to the rotating parts of the printing press which is controlled by at least one vibration sensor arranged on the printing press in such a way that the actuating forces of the actuating member dampen the vibrations.
- the device according to the invention is preferably intended to combat asynchronous interference. Since these disturbances essentially have small excitation energies, they can be set using relatively small actuating forces (compared to the total drive power) can be damped.
- the vibrations are detected by at least one vibration sensor.
- the data determined by the vibration sensor are evaluated and lead to the actuation of an actuating element which is designed as an active actuator.
- the actuating forces applied by the actuator counteract the forces of the vibration excitation, so that damping occurs.
- the damping of the non-synchronous interference prevents duplication, so that the print quality improves.
- the actuator can be designed as a controllable eddy current brake. This is controlled according to the excitation frequency and thus actively intervenes in the overall system, as a result of which the asynchronous vibrations are eliminated.
- the actuating element can be formed by a drive motor or an additional motor of the printing press.
- the torque of a drive motor can be influenced, for example, by means of suitable components of the power electronics as a function of the data determined by the vibration sensor, so that the drive motor itself forms the actuating element and is used to reduce the vibration.
- This increases the dual function of the drive motor, because on the one hand it delivers the drive power and on the other hand it has a vibration-damping effect.
- an additional motor can also be present in the drive train of the printing press, which motor is controlled accordingly in order to reduce vibrations.
- vibration sensor and the actuator are arranged in a control loop of a damping control device.
- Training as a control loop always ensures that occurring, preferably asynchronous, vibrations are corrected to zero, as a result of which optimal damping can be achieved.
- a plurality of vibration sensors and / or actuators are distributed over the drive train, in particular via a gear train, of the printing press.
- the vibration forms required for damping can be derived very precisely, which are then preferably fed - possibly in a revised form - to several active actuators of the drive train.
- the invention further relates to a method for damping mechanical vibrations which reduce print quality in the printing medium-carrying system of a printing press, the vibrations being recorded as a measured variable and used to generate actuating forces which have a vibration-damping effect on the printing medium-carrying system.
- asynchronous vibrations that do not occur periodically with the revolutions of the rotating parts of the printing press are detected and damped.
- the drawing illustrates the invention using various exemplary embodiments. It shows a schematic representation of a printing press with a device for vibration damping.
- the figure shows a printing press 1 which has a plurality of printing units 2.
- Each printing unit 2 has a plurality of cylinders and rollers, of which - for the sake of simplicity - only a part is shown.
- Each printing unit 2 is powered by a drive motor (Electric motor) M1, M3, M5, M n , M n + 2 , M n + 4 driven.
- the individual printing units 2 are Vibration sensor S2; S3, S4; S5; S n ; S n + 2 ; S n + 4 assigned, which are connected to a control device 3.
- the far left in the figure printing unit 2 has the drive motor M1, which acts on the drive train of the printing press 1.
- One of the rollers / cylinders of the printing unit 2 is assigned a vibration sensor S2, which is connected to the control device 3. From the control device 3 leads an operative connection to the drive motor M1.
- the vibration sensor S2 senses occurring vibrations of the associated printing unit 2 and forwards corresponding data to the control device 3. This carries out an evaluation. In particular, periodic vibrations are not detected and a control variable is formed which reacts on the drive motor M 1.
- the drive motor M1 thus forms an actuator B1.
- the control of the motor M1 takes place in such a way that it does not deliver a constant drive torque, but due to the special control by the control device 3 additionally applies actuating forces which counteract the asynchronous vibrations, so that overall vibration damping results.
- the second printing unit 2 from the left shows a corresponding arrangement in the figure, as with the leftmost printing unit 2, but there is the difference that Several vibration sensors, namely S3 and S4, are provided, which detect the vibrations at different points in the drive train and feed the relevant data to the control device 3.
- a drive motor can be used as an actuator. This is the motor M3.
- the third printing unit 2 from the left in the figure shows a further exemplary embodiment.
- two elements are used as actuators for applying the actuating forces. These are the drive motor M5, which acts as an actuator B5 and an additional motor M 5 ' , which acts at another point on the drive train and acts as an actuator B 5' . Both motors are controlled by the control device 3 in such a way that their given moments are set in accordance with the required drive power and also with regard to the damping of asynchronous vibrations.
- control device 3 additionally controls an eddy current brake W, which actively acts on the associated drive train of the printing unit 2 in order to increase the vibrations that occur dampen.
Description
Die Erfindung betrifft eine Vorrichtung zur Dämpfung von mechanischen Schwingungen von Druckmaschinen.The invention relates to a device for damping mechanical vibrations of printing presses.
Der Antriebsstrang einer Druckmaschine mit den daran gekoppelten Teilen (zum Beispiel Zylinder und Walzen) ist ein System, dessen Dynamik durch Federkonstanten, Trägheitsmomente usw. bestimmt ist. Die drehenden Teile dieses Antriebsstranges können durch folgende Einflüsse zu Schwingungen angeregt werden. Hierbei sind winkelabhängige, über eine Umdrehung wiederkehrende Einflüsse und Einflüsse, die nicht periodisch mit einer Umdrehung wiederkehren, zu unterscheiden. Zu den winkelabhängigen, also synchronen Schwingungen sind wiederkehrende Lastenmomentschwankungen zu zählen, wie sie zum Beispiel durch Kurvengetriebe oder durch Fehler von ein- oder n-tourigen Zahnrädern hervorgerufen werden. Nicht periodisch mit einer Umdrehung wiederkehrende Schwingungen, also asynchrone Schwingungen, können zum Beispiel durch periodische, von der Umlauffrequenz abweichende Anregungen erzeugt werden. Sie treten beispielsweise aufgrund von Riemen, durch Heberschlag oder durch Fehler bei halbtourigen Zahnrädern auf. Auch nicht periodische Rauschvorgänge zum Beispiel die Farbspaltung oder Einflüsse des Papierabzuges, führen zu asynchronen Schwingungen. Ferner können Schwingungen im System durch Parameterschwankungen hervorgerufen werden, die im Vergleich zum Bogenlauf eine geringe Änderungsgeschwindigkeit haben (zum Beispiel öltemperaturschwankungen, die die Grundreibung beeinflussen).The drive train of a printing press with the parts coupled to it (e.g. cylinders and rollers) is a system whose dynamics are determined by spring constants, moments of inertia, etc. The rotating parts of this drive train can be excited to vibrate by the following influences. A distinction must be made here between angle-dependent influences that recur over one revolution and influences that do not recur periodically with one revolution. Recurring load torque fluctuations are to be counted among the angle-dependent, i.e. synchronous vibrations, such as those caused by cam gears or by errors in single or n-speed gearwheels. Vibrations that do not recur periodically with one revolution, that is to say asynchronous vibrations, can be generated, for example, by periodic excitations that deviate from the rotational frequency. They occur, for example, due to belts, lifter knocks, or errors in half-speed gears. Even non-periodic noise processes, such as color splitting or the influence of the paper print, lead to asynchronous vibrations. Furthermore, vibrations in the system can be caused by parameter fluctuations that have a low rate of change compared to sheet travel (for example, oil temperature fluctuations that influence the basic friction).
Viele winkelsynchrone Störungen besitzen eine hohe Anregungsenergie. Die daraus resultierenden, über eine Umdrehung periodischen Schwingungsformen beeinflussen jedoch die Druckqualität im Hinblick auf ein Dublieren nicht merklich, da zum Zeitpunkt der Papierübergabe die drehenden Teile der Druckmaschine immer die gleiche Winkellage einnehmen. Nicht synchrone Störungen machen sich jedoch bei der Druckqualität bemerkbar. Sie führen zum Dublieren, da die Winkellage der drehenden Teile der Druckmaschine bei der Bogenübergabe Schwankungen unterworfen ist (siehe z.B. DE-B-2835960). Der Einfluß dieser Störungen macht sich aufgrund ihrer meist geringen Anregungsenergie nur oftmals wesentlich dann bemerkbar, wenn Eigenfrequenzen der Druckmaschine angeregt werden, in denen die Dämpfung gering ist. Die vorstehend erwähnten langsamen Parameterschwankungen beeinflussen das Dublieren nicht.Many angularly synchronous disturbances have a high excitation energy. The resulting one Rotation of periodic waveforms, however, do not have a noticeable effect on the print quality with regard to duplication, since at the time of the paper transfer the rotating parts of the printing press always take the same angular position. However, non-synchronous disturbances are noticeable in the print quality. They lead to duplication, since the angular position of the rotating parts of the printing press is subject to fluctuations when the sheet is transferred (see, for example, DE-B-2835960). Due to their usually low excitation energy, the influence of these disturbances is often only noticeable when natural frequencies of the printing press are excited in which the damping is low. The slow parameter fluctuations mentioned above do not affect duplication.
Es ist bekannt, zur Reduzierung von mechanischen Schwingungen die Seitenwände der Druckmaschine zu verstärken und/oder verstärkte Zahnräder sowie weitere verstärkte Bauteile einzusetzen. Diese Maßnahmen sind aufwendig, erhöhen das Gewicht der Druckmaschine erheblich und führen nicht immer zum gewünschten Erfolg.It is known to reinforce the side walls of the printing press and / or to use reinforced gears and other reinforced components to reduce mechanical vibrations. These measures are complex, increase the weight of the printing press considerably and do not always lead to the desired success.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Dämpfung von mechanischen Schwingungen von Druckmaschinen anzugeben, um die Druckqualität zu verbessern.The invention is therefore based on the object of specifying a device and a method for damping mechanical vibrations of printing presses in order to improve the print quality.
Diese Aufgabe wird erfindungsgemäß gelöst durch mindestens ein, den drehenden Teilen der Druckmaschine zugeordnetes Betätigungsglied, das von mindestens einem an der Druckmaschine angeordneten Schwingungsaufnehmer derart angesteuert wird, daß die Stellkräfte des Betätigungsgliedes die Schwingungen dämpfen. Mit der erfindungsgemäßen Einrichtung sollen vorzugsweise die asynchronen Störungen bekämpft werden. Da diese Störungen im wesentlichen kleine Anregungsenergien besitzen, können sie mittels verhältnismäßig kleiner Stellkräfte (im Vergleich zur gesamten Antriebsleistung) gedämpft werden. Die Schwingungen werden erfindungsgemäß von mindestens einem Schwingungsaufnehmer erfaßt. Die vom Schwingungsaufnehmer ermittelten Daten werden ausgewertet und führen zur Ansteuerung eines Betätigungsgliedes, das als aktives Stellglied ausgebildet ist. Die vom Betätigungsglied aufgebrachten Stellkräfte wirken den Kräften der Schwingungsanregung entgegen, so daß sich eine Dämpfung einstellt. Durch die Bedämpfung der nicht synchronen Störungen ist ein Dublieren verhindert, so daß sich die Druckqualität verbessert.This object is achieved according to the invention by at least one actuator assigned to the rotating parts of the printing press, which is controlled by at least one vibration sensor arranged on the printing press in such a way that the actuating forces of the actuating member dampen the vibrations. The device according to the invention is preferably intended to combat asynchronous interference. Since these disturbances essentially have small excitation energies, they can be set using relatively small actuating forces (compared to the total drive power) can be damped. According to the invention, the vibrations are detected by at least one vibration sensor. The data determined by the vibration sensor are evaluated and lead to the actuation of an actuating element which is designed as an active actuator. The actuating forces applied by the actuator counteract the forces of the vibration excitation, so that damping occurs. The damping of the non-synchronous interference prevents duplication, so that the print quality improves.
Nach einer Weiterbildung der Erfindung kann das Betätigungsglied als steuerbare Wirbelstrombremse ausgebildet sein. Diese wird - entsprechend der Anregungsfrequenz - angesteuert und greift somit aktiv in das Gesamtsystem ein, wodurch die asynchronen Schwingungen eliminiert werden.According to a development of the invention, the actuator can be designed as a controllable eddy current brake. This is controlled according to the excitation frequency and thus actively intervenes in the overall system, as a result of which the asynchronous vibrations are eliminated.
Zusätzlich oder alternativ ist es auch möglich, daß das Betätigungsglied von einem Antriebsmotor oder einem zusätzlichen Motor der Druckmaschine gebildet wird. Das Moment von einem Antriebsmotor läßt sich zum Beispiel mittels geeigneter Bauelemente der Leistungselektronik in Abhängigkeit der vom Schwingungsaufnehmer ermittelten Daten beeinflussen, so daß der Antriebsmotor selbst das Betätigungsglied bildet und zur Schwingungsreduzierung herangezogen wird. Damit wächst dem Antriebsmotor eine Doppelfunktion zu, da er einerseits die Antriebsleistung liefert und andererseits schwingungsdämpfend wirkt. In entsprechender Weise kann im Antriebsstrang der Druckmaschine auch ein zusätzlicher Motor vorhanden sein, der zur Schwingungsreduzierung entsprechend angesteuert wird.Additionally or alternatively, it is also possible for the actuating element to be formed by a drive motor or an additional motor of the printing press. The torque of a drive motor can be influenced, for example, by means of suitable components of the power electronics as a function of the data determined by the vibration sensor, so that the drive motor itself forms the actuating element and is used to reduce the vibration. This increases the dual function of the drive motor, because on the one hand it delivers the drive power and on the other hand it has a vibration-damping effect. In a corresponding manner, an additional motor can also be present in the drive train of the printing press, which motor is controlled accordingly in order to reduce vibrations.
Vorteilhaft ist es ferner, wenn der Schwingungsaufnehmer und das Betätigungsglied in einem Regelkreis einer Dämpfungs-Regelungseinrichtung angeordnet sind. Durch die Ausbildung als Regelkreis ist stets gewährleistet, daß auftretende, vorzugsweise asynchrone Schwingungen auf Null ausgeregelt werden, wodurch eine optimale Bedämpfung erzielt werden kann.It is also advantageous if the vibration sensor and the actuator are arranged in a control loop of a damping control device. Through the Training as a control loop always ensures that occurring, preferably asynchronous, vibrations are corrected to zero, as a result of which optimal damping can be achieved.
Vorzugsweise ist vorgesehen, daß mehrere Schwingungsaufnehmer und/oder Betätigungsglieder über den Antriebsstrang, insbesondere über einen Zahnradzug, der Druckmaschine verteilt angeordnet sind. Mittels der Vielzahl der Schwingungsaufnehmer lassen sich die zur Dämpfung erforderlichen Schwingungsformen sehr präzise ableiten, die dann vorzugsweise - gegebenenfalls in überarbeiteter Form - mehreren aktiven Betätigungsgliedern des Antriebsstranges zugeleitet werden.It is preferably provided that a plurality of vibration sensors and / or actuators are distributed over the drive train, in particular via a gear train, of the printing press. By means of the large number of vibration pickups, the vibration forms required for damping can be derived very precisely, which are then preferably fed - possibly in a revised form - to several active actuators of the drive train.
Die Erfindung betrifft ferner ein Verfahren zur Dämpfung von druckqualitätsmindernden mechanischen Schwingungen im bedruckstofführenden System einer Druckmaschine, wobei die Schwingungen als Meßgröße erfaßt und zur Erzeugung von Stellkräften herangezogen werden, die auf das bedruckstofführende System schwingungsdämpfend wirken. Vorzugsweise werden nicht periodisch mit den Umdrehungen der drehenden Teile der Druckmaschine auftretende, also asynchrone Schwingungen, erfaßt und gedämpft.The invention further relates to a method for damping mechanical vibrations which reduce print quality in the printing medium-carrying system of a printing press, the vibrations being recorded as a measured variable and used to generate actuating forces which have a vibration-damping effect on the printing medium-carrying system. Preferably, asynchronous vibrations that do not occur periodically with the revolutions of the rotating parts of the printing press are detected and damped.
Die Zeichnung veranschaulicht die Erfindung anhand verschiedener Ausführungsbeispiele. Sie zeigt in schematischer Darstellung eine Druckmaschine mit einer Vorrichtung zur Schwingungsdämpfung.The drawing illustrates the invention using various exemplary embodiments. It shows a schematic representation of a printing press with a device for vibration damping.
Die Figur zeigt eine Druckmaschine 1, die mehrere Druckwerke 2 aufweist. Jedes Druckwerk 2 besitzt eine Vielzahl von Zylindern und Walzen, von denen - der Einfachheit halber - nur ein Teil dargestellt ist. Jedes Druckwerk 2 wird von einem Antriebsmotor
(Elektromotor) M₁, M₃, M₅, Mn, Mn+2, Mn+4 angetrieben. Den einzelnen Druckwerken 2 sind
Schwingungsaufnehmer S₂; S₃, S₄; S₅; Sn; Sn+2; Sn+4 zugeordnet, die mit einer Regelungseinrichtung 3 verbunden sind.The figure shows a printing press 1 which has a plurality of

Die Figur verdeutlicht verschiedene Ausführungsformen der Erfindung, die nachstehend näher erläutert werden sollen, wobei jedoch auch noch weitere, nicht dargestellte Ausführungsformen im Bereich der Erfindung liegen.The figure illustrates various embodiments of the invention, which are to be explained in more detail below, although further embodiments, not shown, are also within the scope of the invention.
Das ganz links in der Figur liegende Druckwerk 2 besitzt den Antriebsmotor M₁, der auf den Antriebsstrang der Druckmaschine 1 wirkt. Einer der Walzen/Zylinder des Druckwerks 2 ist ein Schwingungsaufnehmer S₂ zugeordnet, der an die Regelungseinrichtung 3 angeschlossen ist. Von der Regelungseinrichtung 3 führt eine Wirkverbindung zum Antriebsmotor M₁.The far left in the
Es ergibt sich folgende Funktionsweise:
Der Schwingungsaufnehmer S₂ sensiert auftretende Schwingungen des zugehörigen Druckwerks 2 und leitet entsprechende Daten an die Regelungseinrichtung 3 weiter. Diese nimmt eine Auswertung vor. Insbesondere werden nicht periodische Schwingungen erfaßt und es wird eine Steuergröße gebildet, die auf den Antriebsmotor M₁ rückwirkt. Der Antriebsmotor M₁ bildet somit ein Betätigungsglied B₁. Die Ansteuerung des Motors M₁ erfolgt derart, daß er nicht ein konstantes Antriebsmoment liefert, sondern aufgrund der besonderen Ansteuerung durch die Regelungseinrichtung 3 zusätzlich Stellkräfte aufbringt, die den asynchronen Schwingungen entgegenwirken, so daß sich insgesamt eine Schwingungsdämpfung ergibt.This results in the following functionality:
The vibration sensor S₂ senses occurring vibrations of the associated
Das zweite Druckwerk 2 von links zeigt in der Figur eine entsprechende Anordnung, wie beim ganz links liegenden Druckwerk 2, wobei jedoch der Unterschied besteht, daß mehrere Schwingungsaufnehmer, nämlich S₃ und S₄, vorgesehen sind, die an verschiedenen Stellen des Antriebsstranges die Schwingungen erfassen und die betreffenden Daten der Regelungseinrichtung 3 zuführen. Als Betätigungsglied kommt wiederum ein Antriebsmotor in Frage. Dies ist der Motor M₃.The
Das in der Figur dritte Druckwerk 2 von links zeigt ein weiteres Ausführungsbeispiel. Es ist lediglich ein Schwingungsaufnehmer S₅ vorhanden, der an die Regelungseinrichtung 3 angeschlossen ist. Als Betätigungsglieder zum Aufbringen der Stellkräfte kommen jedoch zwei Elemente zum Einsatz. Dies sind der Antriebsmotor M₅, der als Betätigungsglied B₅ wirkt und ein zusätzlicher, an einer anderen Stelle des Antriebsstranges angreifender Motor M5', der als Betätigungsglied B5' wirkt. Beide Motoren werden von der Regelungseinrichtung 3 derart angesteuert, daß ihre abgegebenen Momente entsprechend der erforderlichen Antriebsleistung und auch im Hinblick auf die Dämpfung asynchroner Schwingungen eingestellt werden.The
Bei dem vierten Druckwerk von links ist eine Anordnung gemäß dem ganz links liegenden Druckwerk 2 vorgesehen, wobei jedoch der Unterschied besteht, daß die Regelungseinrichtung 3 zusätzlich eine Wirbelstrombremse W ansteuert, die aktiv auf den zugehörigen Antriebsstrang des Druckwerks 2 wirkt, um die auftretenden Schwingungen zu dämpfen.In the fourth printing unit from the left, an arrangement according to the
Aus alledem wird deutlich, daß die beschriebenen Ausführungsformen nur Beispiele sind, die sich in beliebiger Kombination und auch in erweitertem Umfange mit mehreren Schwingungsaufnehmern und/oder Betätigungsgliedern einsetzen lassen.It is clear from all of this that the described embodiments are only examples that can be used in any combination and also in an extended scope with several vibration sensors and / or actuators.
