Abstract
Description
Druckbogen werden in Druckmaschinen vielfach durch Unterdruck auf einem Transportband fixiert. Dabei werden die Druckbogen durch den Druckunterschied oberhalb und unterhalb des Bogens auf dem Transportband gehalten. Das Transportband weist dabei in der Regel Öffnungen auf, die es ermöglichen, dass der Unterdruck an der Unterseite des Druckbogens angreift. Das Transportband weist dabei über die gesamte Arbeitsbreite Öffnungen auf, um alle Druckbogenformate, möglichst bis zum Rand des Druckbogens, sicher auf dem Transportband zu fixieren. Eine feste Zuordnung einzelner Öffnungen in dem Transportband bezogen auf die Bogenformatkante ist in der Regel nicht gegeben.Printing sheets are often fixed in printing presses by vacuum on a conveyor belt. The sheets are held by the pressure difference above and below the sheet on the conveyor belt. As a rule, the conveyor belt has openings which make it possible for the underpressure to act on the underside of the printed sheet. The conveyor belt has openings over the entire working width in order to securely fix all signature formats, preferably to the edge of the signature, on the conveyor belt. A fixed assignment of individual openings in the conveyor belt with respect to the sheet format edge is not given in the rule.
Charakteristisch ist für Bogendruckmaschinen, dass Bogenformate unterschiedlicher Länge und Breite verarbeitet werden können. Bei Bogenformaten unterhalb des Maximalformats sind somit während des Durchlaufs des Bogens durch das Druckwerk nicht alle Öffnungen durch den Druckbogen bedeckt, so dass in den Randbereichen erheblich Luft in die unterhalb des Transportbandes angeordneten Saugkammern strömt. Dies führt zu Druckverlusten und aufgrund des großen Druckunterschieds auch zu starken, unerwünschten Luftströmungen.Characteristic for sheet-fed presses is that sheet formats of different lengths and widths can be processed. In the case of sheet sizes below the maximum format, not all openings are thus covered by the printing sheet during the passage of the sheet through the printing unit, so that considerable air flows into the suction chambers arranged below the conveyor belt in the edge regions. This leads to pressure losses and due to the large pressure difference also to strong, unwanted air currents.
Bei Bogendruckmaschinen ist es üblich, den Druckbogen relativ zum Transportsystem mittig auszurichten. Die mittige Ausrichtung des Druckbogens wird schematisch in der
Speziell sind die Anforderungen bei Tintenstrahldruckern hoch, da der einzelnen Tintentropfen auf den Bedruckstoff frei fliegend aufgetragen wird. Luftverwirbelungen können dabei zu Störungen führen, da der Tropfen durch die Luftströmungen nicht an seinen vorgesehen Zielort auf dem Druckbogen gelangt. Bei lösemittelhaltigen Tinten können Luftströmungen auch ein vorzeitiges Antrocknen der Tinte am Tintenstrahlkopf oder der Tinte während des Flugs bewirken.Specifically, the requirements of inkjet printers are high, as the single ink drop is applied to the substrate freely flying. Air turbulence can lead to disruptions, since the drop does not reach its intended destination on the printed sheet due to the air currents. For solvent-based inks, air currents can also cause premature drying of the ink at the ink-jet head or ink during flight.
Das Tintenstrahldruckwerk besteht aus einer Vielzahl an einer geeigneten Stelle neben- und gegeben falls hintereinander angeordneten Druckköpfen, wobei jeder Druckkopf wieder eine große Anzahl einzelner Düsen aufweisen kann, aus denen die Tinte oder der Beschichtungsstoff auf den Bedruckstoff aufgespritzt wird.The ink jet printing unit is composed of a plurality of suitable place beside and if arranged in succession printheads, each printhead may again have a large number of individual nozzles from which the ink or the coating material is sprayed onto the substrate.
Tintenstrahldrucker können auf der Ventiltechnik (Valve-Technik) beruhen. Einer solches Drucksystem besteht im Wesentlichen aus einem Tinten-System, indem die Tinte oder der Beschichtungsstoff unter geringem Druck gehalten wird, einer elektronischen Steuerung und einem Druckkopf, der meist über flexible Leitungen mit den übrigen Teilen verbunden ist. Die Tinte oder der Beschichtungsstoff wird von dem Tintensystem zu dem Druckkopf transportiert und versorgt dort die Düse bzw. die Düsen. Diese Düsen sind wiederum mit einfachen Ventilen ausgestattet, die sich öffnen und schließen lassen. Wird ein Tropfen benötigt, öffnet die Elektronik das Ventil und die Tinte wird unter Druck herausgedrückt.Inkjet printers can be based on the valve technology (Valve technique). Such a printing system consists essentially of an ink system in which the ink or the coating material is kept under low pressure, an electronic control and a print head, which is usually connected via flexible lines with the other parts. The ink or paint is transported from the ink system to the printhead where it supplies the nozzle (s). These nozzles are again equipped with simple valves that open and close. When a drop is needed, the electronics opens the valve and the ink is squeezed out under pressure.
Die andere Gruppe der Tintenstrahldrucker beruht auf der Impulstechnik. Hierbei werden zwei Technologien unterschieden: Die Piezotechnologie und die Bubble-Jet Technologie.The other group of inkjet printers is based on impulse technology. There are two different types of technology: piezo technology and bubble jet technology.
Bei der Piezo-Technologie wird die Tinte oder der Beschichtungsstoff unter geringem Druck in die Düse geführt, dass die Tinte oder der Beschichtungsstoff nur durch die Oberflächenspannung in der Düse zurückgehalten wird. Wird ein Tropfen benötigt, wird Spannung an ein Piezokristall in der Düse angelegt. Dadurch biegt bzw. verformt sich das Kristall, reduziert das Volumen des Hohlraums und ein Tropfen wird aus der Düse geschleudert. Das Piezo-Kristall nimmt dann wieder seine ursprüngliche Form an. Die Kräfte der Oberflächenspannung ziehen mehr Tinte oder Beschichtungsstoff aus dem Tintenvorrat, um die Düse wieder aufzufüllen.In piezo technology, the ink or coating material is introduced into the nozzle under low pressure so that the ink or coating material is retained only by the surface tension in the nozzle. If a drop is needed, voltage is applied to a piezocrystal in the nozzle. As a result, the crystal bends or deforms, reduces the volume of the cavity and a drop is thrown out of the nozzle. The piezo crystal then returns to its original shape. The surface tension forces more ink or coating material from the ink supply to replenish the nozzle.
Bei der Bubble-Jet Technologie wird eine elektrische Spannung an zwei Pole gelegt. Als Ergebnis des Widerstands zwischen den Polen entsteht soviel Hitze, dass eine Dampfblase erzeugt wird. Während die Blase sich ausdehnt, schleudert sie einen Tintentropfen aus der Düse. Wenn die Spannung nicht mehr an den Polen anliegt, fällt die Blase in sich zusammen. Durch die Oberflächenspannung füllt sich die Düse wieder mit Tinte bzw. Beschichtungsstoff.In bubble jet technology, an electrical voltage is applied to two poles. As a result of the resistance between the poles is so much heat that a vapor bubble is generated. As the bubble expands, it hurls an ink drop from the nozzle. If the voltage is no longer applied to the poles, the bubble collapses. Due to the surface tension, the nozzle fills again with ink or coating material.
Die drei Technologien Valve-Tintenstrahldruck, Piezo-Tintenstrahldruck und Bubble-Jet werden im Sinne der Erfindung durch den Begriff Tintenstrahldruck oder Inkjet subsumiert.The three technologies valve ink jet printing, piezo ink jet printing and bubble jet are subsumed within the meaning of the invention by the term inkjet printing or inkjet.

Gelöst wird die Aufgabe, indem durch Blendeneinrichtungen im Bereich der Druckeinrichtung, zum Beispiel einer Tintenstrahlvorrichtung, stark reduziert wird, während in den umgebenden Bereichen der Unterdruck erhöht ist. Damit soll der Druckbogen außerhalb der Druckereinrichtung auf dem Transportband sicher fixiert werden und gleichzeitig starke Luftströmungen im Bereich der Druckeinrichtung vermieden werden. Durch den geringen Unterdruck im Bereich der Druckeinrichtung kann sich der Druckbogen von dem Saugband wieder abheben. Diese ist dann insbesondere der Fall, wenn ein Druckbogen vorab in einem anderem Druckverfahren, zum Beispiel in dem Offsetdruckverfahren, bedruckt wurde und anschließend im Tintenstrahldruckverfahren in einem Tintenstrahldrucker individualisiert werden soll. Oftmals weisen die vorbedruckten Druckbogen durch die Beanspruchung im vorangegangen Druckverfahren eine hohe Eigenspannung und Welligkeit auf, sodass erforderlich ist den Druckbogen auch während des Durchlaufs durch das Druckwerk mit einem hohen Unterdruck auf das Saugband zu fixieren. Die verringerte Haltekraft im Bereich des Druckwerkes kann somit zu erheblichen Druckstörungen führen, da Abstandsabweichungen zwischen der Austrittsöffnung des Tintenstrahlkopfs und der Bedruckstoffoberfläche die Druckqualität empfindlich stören können. Dies ist unter anderem bei welligen und/oder nicht plan liegenden Druckbogen der Fall.The object is achieved by greatly reduced by aperture devices in the region of the printing device, for example an ink jet device, while the negative pressure is increased in the surrounding regions. Thus, the sheet should be securely fixed outside the printer device on the conveyor belt and at the same time strong air currents in the area of the printing device can be avoided. Due to the low negative pressure in the region of the printing device, the printed sheet can lift off the suction belt again. This is the case in particular if a printed sheet has been printed in advance in another printing process, for example in the offset printing process, and then is to be individualized in the inkjet printing process in an inkjet printer. Often, the pre-printed sheets by the stress in the previous printing process on a high residual stress and waviness, so it is necessary to fix the sheet during the passage through the printing unit with a high negative pressure on the suction belt. The reduced holding force in the area of the printing unit can thus lead to considerable pressure disturbances, since distance deviations between the outlet opening of the inkjet head and the printing substrate surface can seriously disturb the print quality. This is the case, among other things, with wavy and / or non-planar printed sheets.

Sinnvolle Weiterbildungen ergeben sich aus den jeweiligen Unteransprüchen.The present invention is accordingly based on a device of the type resulting from the preamble of
