Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Druckluftversorgung einer Druckmaschine.The The invention relates to a method and a device for compressed air supply a printing press.
An einer Vielzahl von Stellen der Druckmaschinen wird Blas- und/oder Saugluft gebraucht. Dies betrifft beispielsweise im Bereich des Anlegers die Vorlockerung und Vereinzelung der Bogen, in der Anlage die Förderung und die Ausrichtung, im Druckwerk die abschmierfreie Förderung sowie im Ausleger die Förderung und die Ablage der Bogen. Dabei ist es erforderlich, die zum Abnehmen und Vereinzeln, zum Fördern sowie wieder Abbremsen der Bogen dienenden Blas- und/oder Saugluft entsprechend der Bedruckstoffart und Stärke, dem Bogenformat, der sujetbedingten Farbverteilung auf dem Bogen u. a. anzupassen. Bei modernen Druckmaschinen mit einer großen Anzahl von Druckwerken sowie vor- und nachgeordneten Aggregaten ist die Anzahl der Druckmittelverbraucher dementsprechend groß. Die Leistung der zentralen Blas- und/oder Saugluftversorgungseinrichtung muss dementsprechend ausreichend groß dimensioniert werden.At a variety of bodies of printing presses is blowing and / or Used suction air. This applies for example in the area of Investor's pre-loosening and singling the bow, in the plant the promotion and the alignment, in the printing unit the lubrication-free Promotion and in the boom promotion and the filing of the bow. It is necessary to lose weight and singulation, to promote and again slowing down the Arc serving blowing and / or suction according to the type of printing material and strength, the sheet format, the subject-related color distribution on the bow u. a. adapt. With modern printing machines with a large number of printing units as well as upstream and downstream Aggregates is the number of pressure fluid consumers accordingly large. The performance of the central blowing and / or Saugluftversorgungseinrichtung must therefore be sufficiently large dimensions.
Der Blas- und/oder Saugluftverbrauch an Druckmaschinen ist zeitlich starken Schwankungen ausgesetzt. Bei Betrieb mehrerer Aggregate einer Druckmaschine ist der Druckmittelverbrauch in kurzen Zeitabschnitten extrem hoch, wobei ansonsten über einen längeren Zeitabschnitt vergleichsweise geringer Verbrauch möglich ist.Of the Blowing and / or suction air consumption at printing machines is timely exposed to strong fluctuations. When operating several units a printing press is the pressure medium consumption in short periods of time extremely high, otherwise over a longer Time period comparatively low consumption possible is.

Nachteilig an dieser Lösung ist, dass es bei einer Zentralluftleitung auslegungsbedingt bei Zu- oder Abschaltung einzelner Komponenten zu Druckschwankungen in der Zentralluftleitung kommt. Da die Druckregelung der Luftversorgung bedeutend träger reagiert als der Zuschalt- oder Abschaltvorgang, werden die Druckschwankungen vom Drucklufter zeuger nicht schnell genug ausgeglichen, so dass die sich über die Zentraldruckluftleitung ausbreitenden Druckschwankungen negativ auf die anderen angeschlossenen Verbraucher auswirken. So kommt es beim Zuschalten großer Querschnitte und plötzlich benötigten größeren Druckluftvolumens zu Druckeinbrüchen in der Zentralluftleitung. Die Folge sind Bogenlaufstörungen, die solange anhalten, bis durch die Regeleinrichtung der Druck in der Zentralleitung wieder stabilisiert ist.adversely At this solution is that it is at a central air line due to design reasons when connecting or disconnecting individual components to pressure fluctuations in the central air line comes. Because the pressure control air supply is much slower than the interconnection or shutdown, the pressure fluctuations from the compressed air generator not balanced fast enough, so that over the central compressed air line propagating pressure fluctuations negative affect the other connected consumers. So come it when connecting large cross sections and suddenly needed larger compressed air volume to pressure drops in the central air line. The consequence is sheet run disturbances, the pause until the control by the pressure in the central line is stabilized again.

Diese Einrichtung hat zwar gegenüber einer zentralen Luftversorgung einer Druckmaschine den Vorteil, dass sich Schaltvorgänge nicht nachteilig auf andere Blas- und/oder Saugluftverbraucher auswirken können, demgegenüber aber den Nachteil, dass eine große Anzahl von Luftversorgungseinheiten benötigt wird. Der große technische Aufwand verursacht entsprechend hohe Kosten. Auch bei dieser Einrichtung zur Blas- und/oder Saugluftversorgung lassen sich bei Schaltvorgängen, negativ wirkende kurzzeitige Druckluftschwankungen in der Versorgungsleitung nicht vermeiden.These Although device has a central air supply a printing press has the advantage that switching operations not adversely affect other blow and / or Saugluftverbraucher can, in contrast, but the disadvantage that a large number of air supply units needed becomes. The great technical effort caused accordingly high costs. Even with this device for blowing and / or Saugluftversorgung leave during switching operations, negative-acting short-term Avoid compressed air fluctuations in the supply line.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Druckluftversorgung einer Druckmaschine derartig zu verbessern, dass Schaltvorgänge weitgehend ohne Rückwirkung auf die angeschlossenen Verbraucher möglich sind und der Bogenlauf damit ungestört bleibt.Of the Invention is therefore the object of a method and a Device for compressed air supply to a printing press so to Improve that switching operations largely without feedback to the connected consumers are possible and the Sheet travel thus remains undisturbed.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 und durch eine Vorrichtung mit den Merkmalen des Anspruchs 7 gelöst.According to the invention the object by a method having the features of the claim 1 and solved by a device having the features of claim 7.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. Für die Erfindung ist es unerheblich, ob mit dem Drucklufterzeuger Blasluft oder Saugluft erzeugt wird.advantageous Embodiments are described in the subclaims. For the invention, it is irrelevant whether with the compressed air generator Blowing air or suction air is generated.
Die Erfindung hat den Vorteil, dass beim An- und Abschalten eines Druckluftverbrauchers die daraus resultierenden Druckveränderungen in der Versorgungsleitung andere Druckluftverbraucher nicht beeinflussen. Die Zu- und Abschaltung eines angeschlossenen Druckluftverbrauchers erfolgt nun über den Zwischenschritt der Beschattung eines angepassten Bypasses, über welchen die plötzliche Änderung des Luftverbrauchs durch das zeitlich steuerbare Ventil des Bypasses zeitverzögert vorbereitet oder nachvollzogen wird.The Invention has the advantage that when turning on and off a compressed air consumer the resulting pressure changes in the supply line do not affect other compressed air consumers. The connection and disconnection a connected compressed air consumer is now via the Intermediate step of shading an adapted bypass, about which the sudden change in air consumption delayed by the time-controllable valve of the bypass prepared or reconstructed.
Hierfür wird der Versorgungsleitung über den Bypass phasenweise entsprechend der Trägheit der Regelung des Drucklufterzeugers Druckluft abgeführt oder zugeführt.Therefor the supply line is phased over the bypass according to the inertia of the regulation of the compressed air generator Compressed air discharged or supplied.
Die träge reagierende Regeleinrichtung des Drucklufterzeugers hat nun ausreichend Zeit, den Druck in der zentralen Versorgungsleitung wieder auf den vorgesehenen Wert einzustellen, ohne dass es zu Rückwirkungen auf die anderen Druckluftverbraucher kommt. Bei Erreichen eines von der Steuereinrichtung vorgegebenen Druckes und/oder Schaltvorganges wird der Bypass wieder abgestellt.The slow-acting control device of the compressed air generator now has enough time, the pressure in the central supply line to adjust again to the intended value, without causing repercussions on the other compressed air consumers comes. Upon reaching a from the control device predetermined pressure and / or switching operation the bypass is switched off again.
