Description

Verfahren und Vorrichtung zur Verminderung von Biegeschwingungen von rotierenden Systemen Method and device for reducing bending vibrations of rotating systems
Gegenstand der vorliegenden Erfindung sind ein Verfahren und eine Vorrichtung zur Verminderung der Biegeschwingungen von rotierenden Systemen, insbesondere von rotierenden Walzen. Von besonderer Bedeutung sind derartige Schwingungen bei¬ spielsweise in Tiefdruck-Maschinen, in denen sehr störende Schwingungen der Presseur-Walzen entstehen können.The present invention relates to a method and a device for reducing the bending vibrations of rotating systems, in particular of rotating rollers. Such vibrations are of particular importance, for example in gravure printing machines, in which very disturbing vibrations of the impression roller can occur.
Aus der JP-62-228730 ist bekannt, die Vibrationen einer Welle mit Hilfe von piezo-elektrischen Elementen als Aktuatoren zu unterdrücken. Diese Vibrationen sind offensichtlich bei konstanter Frequenz und sind vorher gemessen worden.It is known from JP-62-228730 to suppress the vibrations of a shaft with the aid of piezoelectric elements as actuators. These vibrations are obviously at a constant frequency and have been measured beforehand.
Aus der DE-C-35 40 645 ist bekannt, niederfrequente Torsions¬ schwingungen in einem Mehrmassen-Torsionsschwinger wie Offset-Rollenrotationsdruckmaschinen im Bereich von 3 bis 16 Hz zu messen und entgegengesetzte Momente zu erzeugen. Für höhere Frequenzen ist dieses Verfahren aber nicht ge¬ eignet. Bei Tiefdruckmaschinen liegen die Schwingungen in einem breiten Frequenzband und bei höheren Frequenzen.From DE-C-35 40 645 it is known to measure low-frequency torsional vibrations in a multi-mass torsional vibrator such as offset web-fed rotary printing presses in the range from 3 to 16 Hz and to generate opposite moments. However, this method is not suitable for higher frequencies. In gravure printing machines, the vibrations are in a broad frequency band and at higher frequencies.
Obwohl Schwingungen von rotierenden Systemen generell sehr störend sind und deshalb versuchsweise mit allen möglichen Mitteln vermindert oder gedämpft werden, sind die Schwingun¬ gen in Tiefdruckwalzen besonders störend. Sie würden nicht nur zu Geräuschbelästigungen, unplanmäßigen Belastungen der Druckmaschinen und Qualitätseinbußen bei den Druckerzeugnis¬ sen, sondern schließlich dazu führen, daß das Weiterdrucken auch aus Sicherheitsgründen nicht mehr möglich ist.Although vibrations of rotating systems are generally very disruptive and are therefore experimentally reduced or damped by all possible means, the vibrations in gravure rollers are particularly disruptive. They would not only lead to noise, unplanned loads on the printing presses and loss of quality in the printed products, but would ultimately lead to the fact that further printing is no longer possible for safety reasons.
Presseur-Systeme haben in Tiefdruck-Maschinen die Aufgabe, die Papierbahn mit dem Druckformzylinder in Kontakt zu bringen. Dies muß mit einer so hohen Anpreßkraft geschehen, daß die Farbe, die im Druckformzylinder vorhanden ist, auf das Papier übertragen wird. Um dies zu erreichen, sind im Laufe der Jahre viele Systeme entwickelt worden. Von beson¬ derer Bedeutung sind Presseure mit und ohne Durchbiegungs- korrektur. Presseur-Walzen ohne Durchbiegungskorrektur be¬ stehen aus einem mit einem Elastomer beschichteten Stahlrohr, an dessen Ende ein Zapfen eingeschweißt ist. Über Spindeln, Pneumatik- oder Hydraulikzylinder wird die Drucklast an den Zapfen des Presseurs eingeleitet und der Presseur dadurch gegen den Druckformzylinder gepreßt. Diese Bauart wird auch Zweiwalzensystem genannt. Das System ohne Durchbiegungskor¬ rektur findet Anwendung in schmalen, langsam laufenden Tief¬ druckrotationsmaschinen.In gravure printing machines, impression roller systems have the task of contacting the paper web with the printing form cylinder bring. This must be done with such a high contact pressure that the ink that is present in the printing form cylinder is transferred to the paper. To achieve this, many systems have been developed over the years. Pressors with and without deflection correction are of particular importance. Imprinter rollers without deflection correction consist of a steel tube coated with an elastomer, at the end of which a pin is welded. The pressure load on the pin of the impression roller is introduced via spindles, pneumatic or hydraulic cylinders and the impression roller is thereby pressed against the printing form cylinder. This design is also called a two-roll system. The system without deflection correction is used in narrow, slow-running rotogravure printing machines.
Mit wachsender Breite und Geschwindigkeit werden die Durch- biegungs- und Erwärmungsprobleme immer größer. Aus diesem Grunde wurde der Presseur ohne Durchbiegungskorrektur auf seiner Rückseite durch eine Stützwalze abgestützt. Diese An¬ ordnung nennt man Dreiwalzensystem. Dreiwalzensysteme sind bei Maschinenbreiten bis maximal 2.000 mm und Drehzahlen bis 40.000/Stunde im Einsatz.With increasing width and speed, the deflection and heating problems increase. For this reason, the impression roller was supported on its back by a back-up roller without deflection correction. This arrangement is called a three-roll system. Three-roller systems are used for machine widths of up to 2,000 mm and speeds of up to 40,000 / hour.
Für Tiefdruckrotationsmaschinen über 2.000 mm Bahnbreite sind zur Beherrschung der Durchbiegungsprobleme besondere Maßnah¬ men erforderlich. Dies hat zur Entwicklung des flexiblen Presseurs geführt, wobei die Achse und der Mantel des Zylin¬ ders keine starre Verbindung haben. Dadurch ist es möglich, den Mantel so durchzubiegen, daß man einen guten Ausgleich der Durchbiegung des Druckformzylinders und somit eine gleichmäßige Druckverteilung und einen parallelen Druck¬ streifen erhält. Es gibt verschiedene Systeme von flexiblen Presseuren. Die wichtigsten sind Biege-Presseure (pneuma¬ tisch) , K2-Presseure (mechanisch) , Nipco-Print-Presseure (hy¬ draulisch) und S-Presseure (hydraulisch) . Für 'die optimale Arbeitsweise des Presseurs müssen folgende Anforderungen er¬ füllt sein: der Presseur muß zylindrisch, also vollkommen rund sein, er soll einen möglichst parallelen Druckstreifen erzeugen, die Bezugstemperatur, die durch die Verformung und Reibung entsteht, soll über die gesamte Breite konstant und nicht höher als ungefähr 45°C und die elastische Presseur-Be- schichtung soll bezüglich ihrer physikalischen Eigenschaften so beschaffen sein, daß im gesamten Drehzahlbereich möglichst keine störenden Schwingungen auftreten.For rotogravure printing machines with a web width of more than 2,000 mm, special measures are required to master the deflection problems. This has led to the development of the flexible impression roller, whereby the axis and the jacket of the cylinder have no rigid connection. This makes it possible to deflect the jacket in such a way that a good compensation of the deflection of the printing form cylinder and thus a uniform pressure distribution and a parallel pressure strip are obtained. There are different systems of flexible impression rollers. The most important are bending pressers (pneumatic), K2 pressers (mechanical), Nipco print pressers (hydraulic) and S pressers (hydraulic). For 'the optimal operation of the impression the following requirements must be filled er¬: the impression roller must cylindrical, so completely round, it should produce a print strip that is as parallel as possible, the reference temperature caused by the deformation and friction should be constant over the entire width and not higher than approximately 45 ° C and the elastic impression coating should be the same with regard to its physical properties be such that as far as possible no disturbing vibrations occur in the entire speed range.
Dennoch treten je nach Presseur-Art und Maschinentyp teil¬ weise bereits bei Bahngeschwindigkeiten von ca. 12 bis 13 m/s störende Schwingungen auf. Nach dem Stand der Technik hat man versucht, Schwingungen zu unterdrücken durch Erhöhung der Dämpfung. Versuche mit unterschiedlich gedämpften Gummi- qualitäten haben jedoch ergeben, daß bei stärkerer Dämpfung (höherer Verlustfaktor) die Presseurschwingungen bereits bei niedriger Drehzahl auftreten.Nevertheless, depending on the impression roller type and machine type, disturbing vibrations sometimes occur even at web speeds of approximately 12 to 13 m / s. In the prior art, attempts have been made to suppress vibrations by increasing the damping. Experiments with differently damped rubber qualities have shown, however, that with greater damping (higher loss factor) the impression vibrations already occur at low speed.
Weitere Untersuchungen der Presseur-Schwingungen haben erge¬ ben, daß die Ursache teilweise schon zu suchen ist bei der Oberflächenbearbeitung (schleifen, polieren) des Beschich- tungsgummis. Es verbleiben immer gewisse Abweichungen vom Rundlauf bzw. von der Zylindrizität. Auch eine gewisse Rest- unwucht kann nicht ausgeschlossen werden. Diese Fehler führen beim Rotieren des Presseurs zu einer erzwungenen Schwingung mit entsprechender Erregung. Weitere Messungen haben ergeben, daß der Presseur bei Auftreten der Schwingung nicht mehr wirklich rund ist, sondern aus dem Kreis ein Vieleck gebildet wird. Die Bildung des Vielecks ist auf unzureichende Rück¬ stellfähigkeit des Gummis zurückzuführen. Diese Rückstellfä¬ higkeit steht in gewisser Korrelation mit der Dämpfung. Je höher die Dämpfung des Elastomers, desto geringer ist die Rückstellfähigkeit, und gleichzeitig wird aber auch mehr Wär¬ me erzeugt. Durch Veränderung der Werkstoffe ist es möglich, bis zu einem gewissen Grad diese störenden Schwingungen in den Bereich höherer Drehzahlen zu verschieben. Es ist jedoch nicht möglich, diese Schwingungen völlig zu vermeiden. In¬ teressant an diesen Meßergebnissen ist, daß die Drehzahl des Presseurs und die Erregerfrequenz viel niedriger sind als die Eigenfrequenz des Presseurs, so daß dieser somit noch nicht in Resonanz ist. Durch die Entstehung von Vielecken, die jeweils die Quotienten aus der Eigenfrequenz und der ent¬ sprechenden Drehzahl sind, entstehen Schwingungen, die das System bei verschiedenen Drehzahlen in Resonanz versetzen. Bei langsamer Rückstellung der Gummibeschichtung bildet sich bereits bei relativ geringer Bahngeschwindigkeit bzw. Presse- ur-Drehzahl ein Vieleck, wodurch es dann zu Presseur-Schwin- gungen (Brummen) , zum Erwärmen und Passerproblemen kommt. Durch Elastomere mit möglichst geringem Verlustfaktor können diese Störungen in höhere Bereiche verschoben, aber letztlich nicht gänzlich vermieden werden. Beispielsweise war es mög¬ lich, diese Presseur-Schwingungen von 13 m/s auf ca. 18 m/s Durchlaufgeschwindigkeit der Papiere zu verschieben.Further investigations of the impression roller vibrations have shown that the cause can already be found in part when the surface treatment (grinding, polishing) of the coating rubber. There are always certain deviations from concentricity or cylindricity. A certain residual unbalance cannot be ruled out. These errors lead to a forced vibration with corresponding excitation when the impression roller rotates. Further measurements have shown that when the vibration occurs, the impression roller is no longer really round, but a polygon is formed from the circle. The formation of the polygon is due to inadequate resilience of the rubber. This resilience has a certain correlation with the damping. The higher the damping of the elastomer, the lower the resilience, and at the same time more heat is generated. By changing the materials, it is possible to shift these disturbing vibrations to a higher degree in the range of higher speeds. However, it is not possible to completely avoid these vibrations. It is interesting about these measurement results that the speed of the The pressur and the excitation frequency are much lower than the natural frequency of the pressur, so that it is not yet in resonance. The formation of polygons, each of which is the quotient of the natural frequency and the corresponding speed, gives rise to vibrations which resonate the system at different speeds. When the rubber coating is slowly reset, a polygon is formed even at a relatively low web speed or press speed, which then causes impression vibrations (humming), heating and registration problems. By using elastomers with the lowest possible loss factor, these disturbances can be shifted to higher ranges, but ultimately not completely avoided. For example, it was possible to shift these impression roller vibrations from 13 m / s to approximately 18 m / s throughput speed of the papers.
Die Erfindung hat sich somit die Aufgabe gestellt, die Biege¬ schwingungen von rotierenden Systemen, insbesondere von ro¬ tierenden Walzen generell zu vermindern. Für den Sonderfall von Schwingungen von Presseur-Walzen in Tiefdruckmaschinen soll hierdurch die Durchlaufgeschwindigkeit des zu bedrucken¬ den Papiers weiter erhöht werden, ohne daß es zu den bekann¬ ten Störungen, wie Brummen, Resonanz, Erwärmung und Passer¬ problemen kommt.The object of the invention is therefore to generally reduce the bending vibrations of rotating systems, in particular of rotating rollers. For the special case of vibrations of impression roller in gravure printing machines, the throughput speed of the paper to be printed is to be increased further without the known disturbances, such as hum, resonance, heating and registration problems.
Es wurde jetzt gefunden, daß diese Aufgabe dadurch gelöst werden kann, daß die durch Unwuchten und/oder zeitlich ver¬ änderliche, radial einwirkende Kräfte erzeugten Schwingungen und deren charakterisierende Parameter in einem breiten Fre¬ quenzband gemessen werden und diese Meßwerte zur Regelung und Ansteuerung von Aktuatoren verwendet werden, die die Schwingungen aktiv unterdrücken. Zur Auslegung des gesamten aktiven Systems ist die Kenntnis der Parameter Kraft, Weg und Frequenz erforderlich. Als Aktuator in Frage kommen vor allen Dingen piezo-elektrische und magneto-striktive oder hydraulische Einheiten. Vorzugsweise ist die Regelung selbst- optimierend und berechnet bei sich verändernden Eigenfrequen- zen die dafür geeigneten Ansteuerungssignale für die Aktuato¬ ren.It has now been found that this object can be achieved in that the vibrations generated by unbalance and / or time-varying, radially acting forces and their characterizing parameters are measured in a broad frequency band and these measured values are used to regulate and control Actuators are used that actively suppress the vibrations. Knowledge of the parameters force, displacement and frequency is required to design the entire active system. Piezoelectric and magneto-strictive or hydraulic units are the most suitable actuators. The control is preferably self-optimizing and calculates with changing natural frequencies. zen the appropriate control signals for the actuators.
Die Verminderung der Schwingungen ist besonders wirksam, wenn der Aktuator möglichst dicht am Entstehungsort der Schwingun¬ gen wirkt. Dadurch ist nicht nur die Verzögerung der Wirksam¬ keit verringert, sondern darüber hinaus erreicht, daß durch den Aktuator nicht an anderer Stelle des Gesamtsystems neue Schwingungen entstehen.The reduction of the vibrations is particularly effective if the actuator acts as close as possible to the point of origin of the vibrations. This not only reduces the delay in effectiveness, but also ensures that the actuator does not cause new vibrations at any other point in the overall system.
Die Messung der Parameter Kraft, Weg und Frequenz, die zur Auslegung des aktiven Systems benötigt werden, ist mit üb¬ lichen Systemen möglich. Die zur Anwendung vorgesehenen Sen¬ soren und Aktuatoren auf hydraulischer Basis sind Stand der Technik; Aktuatoren auf der Basis von Piezoelektrika und magnetostriktiven Materialien sind gegenwärtig in der Ent¬ wicklung. Die Reglersysteme sind hinsichtlich ihrer Software und der Hardware soweit entwickelt, daß ein Einsatz erfolg¬ versprechend ist. Ein aktives System ist bislang in Druckma¬ schinen und anderen rotierenden Systemen zur Verminderung oder Unterdrückung von Schwingungen nicht zum Einsatz gekom¬ men.The measurement of the parameters force, path and frequency, which are required for the design of the active system, is possible with conventional systems. The sensors and actuators provided on a hydraulic basis are state of the art; Actuators based on piezoelectrics and magnetostrictive materials are currently under development. Regarding their software and hardware, the controller systems have been developed to such an extent that their use is promising. An active system has so far not been used in printing presses and other rotating systems for reducing or suppressing vibrations.
Weitere Anwendungsgebiete der Erfindung sind beispielsweise die Verminderung der Schwingungen in Warm- und Kaltwalzwerken sowie in schneilaufenden Brikettier- und Pelletiervorrich¬ tungen, d. h. rotierenden Systemen, in denen starke Kräfte zur Anwendung kommen. Further areas of application of the invention are, for example, the reduction of the vibrations in hot and cold rolling mills and in fast-moving briquetting and pelletizing devices, ie. H. rotating systems in which strong forces are used.
