Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betrieb eines Einzugwerks zu schaffen.The invention has for its object to provide a method for operating a feeder.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of
Die mit der Erfindung im Hinblick auf eine Ausgestaltung des Einzugwerk mit einer Messwalze erzielbaren Vorteile bestehen insbesondere darin, dass eine Bahnspannungsvorgabe über Sollwert vom Leitstand direkt, d. h. z. B. in dN/m, erfolgen kann und nicht indirekt über eine Tänzerkraft bestimmt wird. Damit wird eine tatsächliche konstante Bahnspannung nach dem Einzugwerk/vor dem ersten Druckwerk erzielt. Die Verwendung der direkten Größe, d. h. z. B. in dN/m, vermindert Auswirkungen unterschiedlicher Papiercharakteristik bei wechselnden Papierqualitäten.
Weitere Vorteile gegenüber einem tänzerbasierten Einzugwerk sind u. a. eine kompakte Bauweise, weniger Bahnführungselemente im Papierlauf, ein kürzerer Bahnweg bis zum Druckwerkeinlauf, ein geringerer Wartungsaufwand an mechanischen und pneumatischen Komponenten und/oder Entfall von Bauteilen wie z. B. Tänzerwalze, Pneumatikzylinder, Wegaufnehmer, Leitwalzen.The advantages which can be achieved with the invention with regard to an embodiment of the intake mechanism with a measuring roller are, in particular, that a web tension specification can take place directly above target value, ie, in dN / m, for example, and is not determined indirectly via a dancer force. Thus, an actual constant web tension is achieved after the intake / before the first printing unit. The use of direct size, ie eg in dN / m, reduces the effects of different paper characteristics on changing paper grades.
Other advantages over a dancer-based feeder include a compact design, fewer web guide elements in the paper path, a shorter path to the printing unit inlet, a lower maintenance of mechanical and pneumatic components and / or elimination of components such. B. dancer roller, pneumatic cylinder, Position transducer, guide rollers.
Hinsichtlich des Verfahrens zum Betrieb des Einzugswerkes bzw. zur Bahnspannungsregelung ist insbesondere vorteilhaft, dass die Gefahr von Bahnbruch oder anderen bahnspannungsinduzierten Störungen beim Betrieb der Maschine, insbesondere während des Anfahr- und/oder Abfahrvorganges, erheblich vermindert werden. Durch Korrelation der vorzugebenden Bahnspannung am Einzugwerk bzw. stromaufwärts der Druckwerke mit dem Status der Druckwerke (hinsichtlich Druck-An bzw. -Ab) werden zu hohe Bahnspannungen im den Druckwerken nachfolgenden Bahnweg von vornherein vermieden bzw. die Gefahr drastisch reduziert. Die Verfahrensweise ist zunächst unabhängig von der speziellen Ausbildung des Einzugwerkes (z. B. auch Tänzereinzugwerken), jedoch besonders vorteilhaft in Verbindung mit dem unten genannten zugwalzenbasiertem Einzugwerk.With regard to the method for operating the intake train or for web tension control is particularly advantageous that the risk of web break or other web tension induced disturbances during operation of the machine, especially during the startup and / or shutdown process, are significantly reduced.

Eine Druckmaschine, insbesondere eine Rollenrotationsdruckmaschine, weist einen Rollenwechsler 01 auf, von dem eine Bahn 02, z. B. Material- bzw. Papierbahn, abgerollt wird, durch ein Einzugwerk 03 und eine oder mehrere nachgeordnete Druckwerke 04 geführt wird, und anschließend nach dem Bedrucken direkt oder ggf. einen Überbau 06 mit Wendestangen 07 und/oder anderen Bahnführungseinrichtungen einer Weiterverarbeitungsstufe, z. B. einem Falztrichteraufbau 08 und/oder einem Falzapparat 09, zugeführt wird.A printing machine, in particular a web-fed rotary printing press, has a

Durch das Einzugwerk 03 wird für den Betrieb nun die Bahnspannung S1 zwischen Einzugwerk 03 und der ersten Druckstelle (z. B. erstes Druckwerk 04) festgelegt, welche jedoch auch das gesamte Niveau bis zum Falzapparat 09 mit bestimmt. Die Bahnspannung S2 im Überbau 06 sollte i.d.R. niedriger als die Bahnspannung S1 vor den Druckwerken 04 sein. Bei abgestellten Druckstellen bzw. Druckwerken 04 entspricht die Bahnspannung S2 hinter dem letzten Druckwerk 04 im wesentlichen der Bahnspannung S2. Bei angestellten Druckstellen, d. h. es wird Farbe und ggf. Wasser auf die Bahn 02 gebracht, fällt die Bahnspannung aufgrund der veränderten Spannungs-Dehnungscharakteristik auf dem Weg durch die Druckwerke 04 ab.The
Der Rollenwechsler 01 bzw. dessen Gestell weist sowohl die Tänzereinrichtung 15 als auch das vorteilhafter Weise bahnspannungsregelbare Einzugwerk 03 auf. Auf diese Weise ist verfahrenstechnisch betrachtet für sehr kurze Bahnwege gesorgt und baulich eine raumsparende und kostengünstige Lösung, insbesondere im Zusammenhang mit unten beschriebener Verfahrensweise, gefunden.The

Um Schlupf zwischen Zugwalze 12 und Bahn 02 zu vermeiden, sind ein oder mehrere Andrückrollen 18 einer Andrückvorrichtung - z. B. pneumatisch - anstellbar.To avoid slippage between
Zur korrekten Ermittlung der mittels der Messwalze 17 gemessenen Bahnspannung S1 geht als interne Rechengröße z. B. die Bahnbreite der derzeit eingezogenen Bahn 02 sowie eine Normierung zwischen dem physikalisch gemessenen Parameter (z.B. einer elektrischen Spannung und einer resultierenden Kraft und/oder mechanischen Spannung) ein, welche beispielsweise in der Steuerung eingebbar und, zumindest die Bahnbreite, an einer Anzeige, z. B. dem Leitstand, visualisierbar ist/sind. Als zusätzliche Inputs in das mechanisch-elektrische System (
Wie oben bereits ausgeführt fällt die Bahnspannung bei angestellten Druckstellen wenn Farbe und ggf. Wasser auf die Bahn 02 gebracht wird, aufgrund der veränderten Spannungs-Dehnungscharakteristik auf dem Weg durch die Druckwerke 04 ab, so dass im Überbau 06 eine (erwünschtermaßen) verminderte Bahnspannung S2 herrscht. Im nachfolgend beschriebenen vorteilhaften Verfahren zur Bahnspannungsregelung wird diesem Sachverhalt insbesondere beim Anfahren und/oder Herunterfahren der Maschine Rechnung getragen.As already stated above, the web tension falls at employees pressure points when color and possibly water is placed on the
Wesentlich ist es jedoch, dass beim Anfahren der Maschine nach dem Einziehen der Bahn 02 die Bahnspannung S1 zwischen Einzugwerk 03 und erstem Druckwerk 04 nicht gleich auf einen für den Druckbetrieb erforderlichen Bahnspannungswert FEZW, Betrieb geregelt wird, sondern in Anhängigkeit von der Betriebsstellung bzw. dem Betriebszustand der Druckstellen bzw. Druckwerke 04 auf einen reduzierten Bahnspannungswert FEZW, reduziert hin geregelt wird. Dieser kann als vorgebbarer Sollwert direkt vorgegeben sein oder aber es kann ein Differenzwert zum späteren Bahnspannungswert vorgegeben sein.It is essential, however, that when starting the machine after retraction of the
Beim Fahren (insbesondere beim Anfahren/Abfahren) der Maschine werden demnach korreliert zur Betriebsstellung/Betriebszustand der nachfolgenden Druckwerke unterschiedliche Sollwerte als Bahnspannungswerte FEZW, Betrieb, FEZW, reduziert vorgegeben. D. h., korreliert zum Druck-An-Stellen wird der Sollwert für die Bahnspannung S1 von einem niedrigeren Bahnspannungswert FEZW, reduziert auf einen höheren Bahnspannungswert FEZW, Betrieb geändert. Korreliert zum Druck-Ab-Stellen wird der Sollwert für die Bahnspannung S1 von einem höheren Bahnspannungswert FEZW, Betrieb auf einen niedrigeren Bahnspannungswert FEZW, reduziert geändert.When driving (in particular when starting / stopping) of the machine are therefore correlated to the operating position / operating state of the subsequent printing units different setpoints as web tension values F EZW , operation, F EZW , reduced specified. That is, correlated to pressure on-set, the setpoint value for the web tension S1 is changed from a lower web tension value F EZW reduced to a higher web tension value F EZW operation. Correlated to the print-off position, the desired value for the web tension S1 from a higher web tension value F EZW, operation changed, reduced to a lower web tension value F EZW.
Sind sämtliche Druckstellen noch abgestellt, so wird die Bahnspannung beim Anfahren auf den niedrigeren Bahnspannungswert FEZW, reduziert geregelt und unmittelbar vor, während oder nach dem Druck-An-Signal auf den höheren FEZW, Betreib geregelt. Das selbe geschieht beim Herunterfahren der Maschine in Verbindung mit einem Druck-Ab-Signal.If all pressure points are still turned off, the web tension is regulated when approaching the lower web tension value F EZW , reduced and regulated immediately before, during or after the pressure on signal to the higher F EZW, Betreib . The same happens when the machine shuts down in conjunction with a pressure-off signal.
Zusätzlich kann während des Einziehens (z. B. mit einer reduzierten Bahnspannung FRW, reduziert) und/oder in einer Phase zu Beginn des Anfahrens der Maschine (z. B. mit einer reduzierten Bahnspannung FRW, reduziert) nach dem Einziehen vorgesehen sein, dass die Bahnspannung S1 lediglich durch den Rollenwechsler vorgegeben ist und die Trolleys 18 des Einzugwerkes 03 noch abgestellt sind. Die Zugwalze 12 kann hierbei beispielsweise synchron mit Maschinengeschwindigkeit betrieben werden, ohne dass deren überlagerte Bahnspannungsregelung aktiv ist. So wird in einer vorteilhaften Betriebsweise beim Anfahren der Maschine die Bahnspannungsregelung am Einzugwerk erst nach Erreichen der Betriebsbahnspannung FRW des Rollenwechslers 01 aktiviert. Hierdurch wird ein ruhigerer Bahnspannungsaufbau, insbesondere zwischen Rollenwechsler 01 und erstem Druckwerk 04, erreicht.In addition, during retraction (eg, with a reduced web tension F RW , reduced) and / or in a phase at the start of the startup of the machine (eg, with a reduced web tension F RW , reduced) may be provided after retraction in that the web tension S1 is predetermined only by the roll changer and the

Nach Aktivierung der Bahnspannungsregelung des Einzugwerks 03 wird die Bahnspannung S1 zwischen Einzugwerk 03 und erstem Druckwerk 04 durch das Einzugwerk 03 entsprechend dem jeweiligen Vorgabewert (FEZW, FEZW reduziert) eingestellt.The web tension on the
