Abstract
Eine Bogendruckmaschine umfasst einen Trockner (5). In Bogentransportrichtung (T) nach dem Trockner (5) ist eine Befeuchtungseinrichtung (8) zum auf die nicht bedruckte Bogenseite erfolgenden Rückbefeuchten der Druckbogen (11) angeordnet. Die Befeuchtungseinrichtung (8) ist durch eine Steuerung (29) in Abhängigkeit von Signalen mindestens eines ersten Feuchtesensors (23) angesteuert. Der erste Feuchtesensor (23) ist von unten her auf die vorbeilaufenden Druckbogen (11) gerichtet.A sheet-fed printing machine comprises a dryer (5). Arranged in the sheet transport direction (T) after the dryer (5) is a moistening device (8) for rewetting the printed sheets (11) on the non-printed sheet side. The humidification device (8) is controlled by a controller (29) as a function of signals from at least one first moisture sensor (23). The first moisture sensor (23) is directed from below onto the passing printed sheets (11).
Description
Vorliegende Erfindung betrifft eine Bogendruckmaschine, umfassend einen Trockner.The present invention relates to a sheet-fed printing machine comprising a dryer.
In
Ungünstig daran ist, dass durch die Infrarot- oder Heißluft-Trockner dem Druckbogen Feuchtigkeit entzogen wird und infolgedessen Bogendeformationen auftreten. Durch den Lackauftrag im Lackmodul kann dem Druckbogen die Feuchtigkeit jedoch nicht wieder zugeführt werden, weil dieser Lackauftrag auf das vorher in den Druckwerken aufgedruckte Druckbild erfolgt, welches eine die Druckbogen versiegelnde Wirkung hat.The disadvantage of this is that the infrared or hot air dryer removes moisture from the printed sheet and, as a result, sheet deformation occurs. By applying the varnish in the varnish module, however, the moisture cannot be returned to the printed sheet, because this varnish is applied to the printed image previously printed in the printing units, which has a sealing effect on the printed sheet.
Aufgabe der Erfindung ist, eine Bogendruckmaschine zu schaffen, bei der durch den Trockner hervorgerufene Bogendeformationen vermieden werden.The object of the invention is to provide a sheet printing machine in which sheet deformations caused by the dryer are avoided.
Die Aufgabe wird gelöst durch eine Bogendruckmaschine, umfassend einen Trockner, dadurch gekennzeichnet, dass in Bogentransportrichtung nach dem Trockner eine Befeuchtungseinrichtung zum auf die nicht bedruckte Bogenseite erfolgenden Rückbefeuchten der Druckbogen angeordnet ist, dass die Befeuchtungseinrichtung durch eine Steuerung in Abhängigkeit von Signalen mindestens eines ersten Feuchtesensors angesteuert ist, und dass der erste Feuchtesensor von unten her auf die vorbeilaufenden Druckbogen gerichtet ist.The object is achieved by a sheet-fed printing machine comprising a dryer, characterized in that a humidifying device for re-moistening the printed sheets on the non-printed sheet side is arranged in the sheet transport direction after the dryer, and the humidifying device is controlled by a control as a function of signals from at least one first moisture sensor is controlled, and that the first moisture sensor is directed from below onto the passing printed sheets.
Ein Vorteil der erfindungsgemäßen Bogendruckmaschine ist, dass die mit der Befeuchtungseinrichtung erfolgende Rückbefeuchtung der Druckbogen auf deren nicht bedruckter Bogenseite erfolgt, welche die Rückbefeuchtungsflüssigkeit gut aufnehmen kann.An advantage of the sheet-fed printing machine according to the invention is that the rewetting of the printed sheets, which takes place with the dampening device, takes place on the non-printed sheet side thereof, which can absorb the remoistening liquid well.
Es sind verschiedene Weiterbildungen möglich:Various training courses are possible:
Der erste Feuchtesensor kann in einer Leiteinrichtung für die Druckbogen angeordnet sein.The first moisture sensor can be arranged in a guide device for the printed sheets.
Die Leiteinrichtung kann eine Leitfläche mit Düsen darin aufweisen.The guide device can have a guide surface with nozzles therein.
Die Düsen können Saugdüsen sein.The nozzles can be suction nozzles.
Die Steuerung kann derart programmiert sein, dass der erste Feuchtesensor nur im bezüglich der Bogentransportrichtung mittleren und/oder hinteren Drittel des jeweiligen Druckbogens Messwerte gewinnt.The control can be programmed such that the first moisture sensor only obtains measured values in the middle and / or rear third of the respective printed sheet with respect to the sheet transport direction.
Die Steuerung kann derart programmiert sein, dass sie die im mittleren und/oder hinteren Drittel des jeweiligen Druckbogens gewonnenen Messwerte als Berechnungsbasis zur Ansteuerung der Befeuchtungseinrichtung bei der Befeuchtung des bezüglich Bogentransportrichtung vorderen Drittels dieses oder eines nachfolgenden Druckbogens verwendet.The control system can be programmed in such a way that it uses the measured values obtained in the middle and / or rear third of the respective printed sheet as a calculation basis for controlling the humidification device during the moistening of the third third of this sheet or a subsequent printed sheet with respect to the sheet transport direction.
Der erste Feuchtesensor und ein zweiter Feuchtesensor können mit der Steuerung verbunden sein, wobei in Bogentransportrichtung gesehen der erste Feuchtesensor vor der Befeuchtungseinrichtung und der zweite Feuchtesensor nach der Befeuchtungseinrichtung angeordnet ist.The first moisture sensor and a second moisture sensor can be connected to the controller, the first moisture sensor being arranged in front of the moistening device and the second moisture sensor after the moistening device, as seen in the sheet transport direction.
Der erste Feuchtesensor kann ein Mikrowellensensor sein.The first moisture sensor can be a microwave sensor.
Die Befeuchtungseinrichtung kann eine Sprüheinrichtung sein.The moistening device can be a spray device.
Der Trockner kann ein Wärmetrockner sein.The dryer can be a heat dryer.
