Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Trocknereinrichtung einer Druckmaschine, wobei die Trocknereinrichtung mindestens eine Wärmestrahlereinrichtung umfasst, um Wärmestrahlung auf Druckbogen zu richten, wobei die Trocknereinrichtung mindestens eine Thermolufteinrichtung umfasst, um einen temperierten Luftstrahl auf die Druckbogen zu richten, wobei im Druckbetrieb der Druckmaschine und damit im Trocknungsbetrieb der Trocknereinrichtung die Wärmestrahlereinrichtung mit einer definierten Wärmestrahlerleistung und die Thermolufteinrichtung mit einem definierten Zuluftvolumenstrom, einem definierten Abluftvolumenstrom und einer eine definierte Lufttemperatur bereitstellenden Thermoluftleistung betrieben wird. Erfindungsgemäß wird dann, wenn während des Druckbetriebs eine Störung oder eine Unterbrechung auftritt, während einer ersten Zeitspanne nach Auftreten der Störung oder der Unterbrechung die Wärmestrahlereinrichtung mit verringerter Wärmestrahlerleistung betrieben oder abgeschaltet und die Thermolufteinrichtung mit unveränderten Betriebsparametern betrieben, wobei dann, wenn innerhalb der ersten Zeitspanne die Störung oder Unterbrechung nicht beseitigt wird, die Thermolufteinrichtung für eine sich an die erste Zeitspanne anschließende zweite Zeitspanne mit einem verringerten Zuluftvolumenstrom, einem verringerten Abluftvolumenstrom und einer eine verringerte Lufttemperatur bereitstellenden Thermoluftleistung betrieben wird.

The invention relates to a method for operating a dryer device of a printing machine, wherein the dryer device comprises at least one heat radiating device to direct heat radiation on printed sheets, wherein the dryer device comprises at least one thermal air device to direct a tempered air jet on the press sheets, wherein in the printing operation of the printing press and thus, in the drying operation of the drying device, the heat radiating device is operated with a defined radiant heat output and the thermo-sounding device is operated with a defined supply air volumetric flow, a defined exhaust air volumetric flow and a thermo-air power providing a defined air temperature. According to the invention, when a malfunction or interruption occurs during the printing operation, during a first period of time after the occurrence of the malfunction or interruption, the heat radiating means is operated or turned off with reduced radiant heat output and the thermostating means operates with unchanged operating parameters, if within the first period the disturbance or interruption is not eliminated, the thermal air device is operated for a second time period subsequent to the first time period with a reduced supply air volume flow, a reduced exhaust air volume flow and a thermal air power providing a reduced air temperature.
