Description

Die Erfindung betrifft eine Trocknereinrichtung innerhalb einer Bogendruckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a drying device within a sheet-fed printing machine according to the preamble of claim 1.

[Stand der Technik][State of the art]

Innerhalb von Bogenoffsetdruckmaschinen werden die bedruckten Bogen über Zylinder und Trommeln durch die einzelnen Druckwerke und nach dem letzten Druckwerk durch ein oder mehrere Lackier- und sonstige Veredelungseinrichtungen gefördert. Über Kettensysteme erfolgt der Transport der Bogen von einer letzten Trommel zum Auslegerstapel.Within sheet-fed offset printing machines, the printed sheets are conveyed over cylinders and drums through the individual printing units and, after the last printing unit, through one or more painting and other finishing devices. Chain systems transport the sheets from one last drum to the delivery pile.

Um ein Abschmieren der frisch bedruckten Bogen beim Transport zwischen den Druckwerken, zwischen dem letzten Druckwerk und dem Ausleger bzw. den Lackiereinrichtungen zu vermeiden, sind an einer Vielzahl von Stellen Trocknereinrichtungen vorgesehen. Durch die Trocknereinrichtungen soll ein möglichst schnelles Abtrocknen / Wegschlagen der Farbe / des Lackes erzielt werden, so dass Berührungen der bedruckten Bogenseite mit Bogenführungsblechen oder sonstigen stehenden Teilen keine Beschädigungen an der Druckseite und somit Makulatur verursachen.In order to avoid smearing of the freshly printed sheets during transport between the printing units, between the last printing unit and the boom or the painting, drying devices are provided at a plurality of locations. By the drying devices as fast as possible drying / dissolving the color / the paint should be achieved so that touching the printed sheet side with sheet guide plates or other stationary parts cause no damage to the print side and thus waste.

Auf Lösungsmitteln basierende Druckfarben bzw. Lacke geben beim Trocknen Lösemitteldämpfe ab. Ein derartiger Trocknungsprozess kann durch IR-Strahler beschleunigt werden, da durch die eingetragene Wärme das Ausdünsten des Lösemittels - beschleunigt wird. Eine weitere Beschleunigung erfährt ein derartiger Trocknungsprozess, wenn zusätzlich eine Warmluftbeaufschlagung des Druckproduktes erfolgt, da so der durch den Wärmeeintrag aus dem Bedruckstoff heraustretende Lösemitteldampf abtransportiert wird. Letztlich wird bei derartigen Trocknungsprozessen auch die mit Lösungsmittel und Wasserdampf gesättigte Luft abgesaugt, was durch eine spezielle Absaugvorrichtung erfolgt.Solvent based inks or varnishes release solvent vapors during drying. Such a drying process can be accelerated by IR emitters, since the heat introduced by the evaporation of the solvent - accelerated. A further acceleration undergoes such a drying process, if in addition a hot air is applied to the printed product, since so the heat released by the heat emerging from the printing material solvent vapor is removed. Finally, in such drying processes, the air saturated with solvent and water vapor is sucked off, which takes place by means of a special suction device.

Aus der DE 195 25 453 A1 ist ein Trocknungsverfahren für schnelllaufende Materialbahnen bekannt, bei welchen neben den Trocknungseinrichtungen zusätzlich eine an eine Hochspannungsquelle geschaltete Elektrode vorgesehen ist. Durch den von der Elektrode in Richtung Bedruckstoff (schnelllaufende Materialbahn) bewegten Strom an elektrischen Ladungsträgern erfolgt eine Zerstörung der durch die bewegte Bahn mitgenommenen laminaren Grenzschicht. Diese vom Bedruckstoff (Materialbahn) mitgenommene laminare Grenzschicht hemmt den Stoffaustausch von Lösungsmittel bzw. Wasserdampf aus dem Bedruckstoff, d.h. der Stoffübergangskoeffizient wird verringert. Dieses Trocknungsprinzip mittels Hochspannungselektrode ist jedoch nur bei schnelllaufenden Materialbahnen anwendbar und in der bekannten Form bei Bogendruckmaschinen nicht anwendbar.From the DE 195 25 453 A1 For example, a drying method for high-speed material webs is known in which, in addition to the drying devices, an electrode connected to a high-voltage source is additionally provided. By moving from the electrode in the direction of substrate (high-speed material web) stream of electric charge carriers destruction of the entrained by the moving web laminar boundary layer takes place. This laminar boundary layer entrained by the printing material (web) inhibits the mass transfer of solvent or water vapor from the printing substrate, ie the mass transfer coefficient is reduced. However, this drying principle by means of high-voltage electrode is only applicable to high-speed material webs and not applicable in the known form in sheet-fed presses.

Aus der WO 91/12095 ist eine Vorrichtung zur Reinigung von Bahnen bekannt. Die Vorrichtung weist eine Einrichtung zur Erzeugung einer Korona-Entladung auf. Diese Einrichtung enthält eine Elektrode, die einem Zylinder zugeordnet und mit diesem einen Spalt bildend angeordnet ist. Durch die in dem Spalt gebildete Korona-Entladung wird die zu reinigende Bahn beführt. Der Einrichtung sind Absaugmittel zugeordnet. Die an die Einrichtung zugeführte Spannung wechselt sinusförmig und regelmäßig das Vorzeichen.From the WO 91/12095 a device for cleaning of webs is known. The device has a device for generating a corona discharge. This device includes an electrode associated with a cylinder and arranged with this forming a gap. Due to the corona discharge formed in the gap, the web to be cleaned is performed. The device is associated with suction. The voltage supplied to the device changes sinusoidally and regularly the sign.

Aus der US 5,152,838 A ist eine Einrichtung zum Trocknen eines Beschichtungsmediums bekannt. Darin ist ein Korona-Entladungskopf vorgesehen, der in geringem Abstand zur Bahnoberfläche einer beschichteten Bahn aus isolierendem oder dielektrischem Material in deren Bahnweg und einer Beschichtungsanordnung nachgeordnet angebracht ist. Die Korona-Entladung wird zwischen der noch feuchten und damit elektrisch leitenden Beschichtung gegenüber der Beschichtungsanordnung erzeugt. Daher wird eine die Bahn in diesem Bereich führende Walze nicht als Gegenelektrode zu dem Korona-Entladungskopf benötigt und muss nicht geerdet zu werden.From the US 5,152,838 A a device for drying a coating medium is known. Therein, a corona discharge head is provided, which is arranged at a small distance to the web surface of a coated web of insulating or dielectric material in their path and a coating arrangement downstream. The corona discharge is generated between the still moist and thus electrically conductive coating with respect to the coating arrangement. Therefore, a roller guiding the web in this area is not needed as a counter electrode to the corona discharge head and does not need to be grounded.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Aufgabe der vorliegenden Erfindung ist es daher, eine Trocknereinrichtung gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so dass unter Vermeidung der zuvorstehend genannten Nachteile eine Verbesserung der Trocknungswirkung erzielt wird.The object of the present invention is therefore to expand a drying device according to the preamble of claim 1 such that, while avoiding the above mentioned disadvantages an improvement of the drying effect is achieved.

Gelöst wird diese Aufgabe durch die Merkmale von Anspruch 1.This problem is solved by the features of claim 1.

[Beispiele][Examples]

Gemäß der Erfindung ist vorgesehen, dass der Trocknereinrichtung eine mit einer Hochspannungsquelle (HV) verbundene und diese in Abhängigkeit des Betriebes der Bogendruckmaschine und/oder der Länge der Bogen (B) mit Hochspannung beaufschlagende Elektrode (E) nebst Gegenelektrode zugeordnet ist. Bevorzugt ist dieser Einrichtung noch eine Absaugeinrichtung zugeordnet, vermittels der die durch Wärme und Luft aus dem Bedruckstoff nebst Farbe herausgelösten Dämpfe absaugbar sind.According to the invention, it is provided that the drying device is associated with a high voltage source (HV) and this in response to the operation of the sheet printing machine and / or the length of the sheet (B) with high voltage acting on electrode (E) together with the counter electrode. Preferably, this device is still associated with a suction device, by means of which the extracted by heat and air from the substrate together with color vapors are sucked.

Gemäß einer Ausführungsform der Erfindung ist der Trocknungseinrichtung bevorzugt eine als IR-Strahler ausgebildete Einrichtung zugeordnet, so dass der Bedruckstoff nebst Farb- und/oder Lackschicht gezielt in einer das Lösungsmittel anregenden Wellenlänge beaufschlagbar ist.According to one embodiment of the invention, the drying device is preferably associated with a device designed as an IR emitter, so that the printing material, together with the color and / or lacquer layer, can be specifically acted on in a wavelength that stimulates the solvent.

Gemäß dieser Ausführungsform der Erfindung ist vorgesehen, dass die bewegten Bogen mit IR-Strahlern auf einer Wellenlänge bestrahlt werden, auf der nur das Lösemittel erwärmt wird. Durch die in einem geringen Abstand zur Bogenoberfläche positionierten Elektrode, welche dem IR-Strahler in Bewegungsrichtung des Bogens nachgeordnet ist, wird durch Zerstörung laminarer Luftschichten oberhalb der Bogenoberfläche der Stoffübergangskoeffizient erhöht, was eine Verbesserung der Stoffabfuhr (Ausgasen) von Lösemittel bewirkt. Durch einen zusätzlich aufgebrachten vorgewärmten Luftstrom wird das Ausgasen von Lösemittel aus dem Bedruckstoff zusätzlich erleichtert und gleichzeitig die mit dem Lösemittel / Wasser angereicherte Luft abtransportiert. Letztlich erfolgt durch eine entsprechende Einrichtung eine Absaugung der mit Lösemittel / Wasser angereichten Luft aus dem Bereich der Trocknungseinrichtung und letztlich auch der Druckmaschine.According to this embodiment of the invention it is provided that the moving sheets are irradiated with IR radiators at a wavelength at which only the solvent is heated. By positioned at a small distance to the arc surface electrode, which is arranged downstream of the IR radiator in the direction of movement of the arc, the mass transfer coefficient is increased by destroying laminar air layers above the sheet surface, which causes an improvement of the substance discharge (outgassing) of solvent. By additionally applied preheated air flow, the outgassing of solvent from the substrate is additionally facilitated and at the same time with the solvent / water enriched air transported away. Finally, by means of an appropriate device, an extraction of the air enriched with solvent / water from the area of the drying device and ultimately also the printing machine takes place.

Die erfindungsgemäß mit einer Elektrode nebst Gegenelektrode erweiterte Trocknungseinrichtung kann an einer Vielzahl von Stellen innerhalb der Bogenoffsetdruckmaschine eingesetzt werden. Vorgesehen ist, dass die Beaufschlagung der Elektrode mittels Hochspannung in Abhängigkeit der Druckgeschwindigkeit und/oder der Länge der Druckbogen (Format) erfolgt. Weiterhin ist zu gewährleisten, dass der Abstand der Elektrode zur Oberfläche des Bogens stets den erforderlichen Wert einnimmt. Dabei ist zu beachten, dass den Bogen haltende Einrichtungen, wie z.B. die Greiferfinger der den Bogen führenden Zylinder bzw. der Greifersysteme des Auslegers, nicht mit der Elektrode bzw. der Gegenelektrode in Kollision kommen. Hierbei kann vorgesehen sein, dass die Elektrode bzw. der Träger der Elektrode bzw. die der Elektrode zugeordnete Gegenelektrode beweglich aufgehängt ist und während des Passierens der Greifer bzw. der den Bogen haltenden Einrichtungen Ausweichbewegungen ausführen. Eine derartige bewegliche und in Abhängigkeit der Bogenbewegung gesteuerte Aufhängung der Elektrode bzw. der gesamten Trocknereinrichtung ist insbesondere dann vorzusehen, wenn die erfindungsgemäße Trocknereinrichtung im Ausleger der Druckmaschine (Bogenaufgang) der Schöndruckseite der Bogen zugeordnet sein soll. Die die Bogen haltenden Greifersysteme können die entsprechend nötigen Ausweichbewegungen der Elektrode über an vorgesehenen Orten angebrachte Sensoren steuern. Die Ausweichbewegung der Elektrode u./o. Gegenelektrode gegenüber den Greifersystemen ist nötig, da diese den Greifersystemen im Weg stehen.The drying device according to the invention, which has an electrode and a counterelectrode, can be used at a large number of locations within the sheet-fed offset printing press. It is provided that the application of the electrode by means of high voltage as a function of the printing speed and / or the length of the sheet (format) takes place. Furthermore, it must be ensured that the distance between the electrode and the surface of the sheet always assumes the required value. It should be noted that the bow-holding devices, such as the gripper fingers of the bow-leading cylinder or the gripper systems of the boom, do not come into collision with the electrode or the counter electrode. It can be provided that the electrode or the carrier of the electrode or the counter electrode associated with the electrode is suspended in a mobile manner and execute evasive movements during the passage of the grippers or the devices holding the sheet. Such a movable and in dependence of the sheet movement controlled suspension of the electrode or the entire dryer device is to be provided in particular when the drying device according to the invention in the delivery of the printing press (sheet sunrise) should be assigned to the recto printing side of the sheet. The bow-holding gripper systems can control the appropriate evasive movements of the electrode via attached at designated locations sensors. The evasive movement of the electrode u./o. Counter electrode opposite the gripper systems is necessary because they are the gripper systems in the way.

Durch eine bewegliche und in Abhängigkeit der Bogenbewegung gesteuerte Aufhängung des Trockners bzw. der Elektrode oder der zugeordneten Gegenelektrode gegenüber dem Bogenaufgang im Ausleger können im Aufgang des Auslegers ein oder mehrere erfindungsgemäße Trocknervorrichtungen vorgesehen sein. Dadurch ergibt sich eine Intensivierung der Trocknungswirkung im Auslegerbereich, so dass hohen Bauaufwand verursachende Verlängerungen innerhalb des Auslegers entbehrlich scheinen.By a movable and depending on the bow movement controlled suspension of the dryer or the electrode or the associated counter electrode relative to the arched rise in the boom one or more drying devices according to the invention can be provided in the rising of the boom. This results in an intensification of the drying effect in the boom area, so that high construction costs causing extensions seem dispensable within the boom.

Die erfindungsgemäße Elektrode zur Unterstützung des Trocknungsvorganges ist mit wenigstens einer den Bogen vorzugsweise mit warmer Luft beaufschlagenden Einrichtung versehen. Die durch diese Einrichtung bewirkte Luftströmung ist vorzugsweise dergestalt, dass ein Berühren des Bogens und insbesondere des Bogenendes mit der Elektrode bzw. der Elektrode zugeordneten Teilen nicht möglich ist.The electrode according to the invention for assisting the drying process is provided with at least one device which preferably acts on the sheet with warm air. The air flow caused by this device is preferably such that contact with the arc and in particular with the end of the arc with the electrode or the electrode associated parts is not possible.

Die erfindungsgemäße Elektrode nebst Trocknereinrichtung kann an einer Vielzahl von Stellen innerhalb einer Bogenoffsetdruckmaschine angeordnet sein. So ist es möglich, diese vor dem ersten Offsetdruckwerk in der Bogenführung vorzusehen. Eine derartige Installation ist insbesondere dann bevorzugt, wenn den Druckwerken eine Grundierung in Form eines Flexodruckwerkes vorgeschaltet ist.The electrode according to the invention together with the drying device can be arranged at a plurality of locations within a sheet-fed offset printing press. So it is possible to provide these before the first offset printing unit in the sheet guide. Such an installation is particularly preferred when the printing units a primer in the form of a flexographic printing is preceded.

Die erfindungsgemäße Trocknereinrichtung kann auch zwischen den Druckwerken innerhalb der Bogenführung, der Schöndruckseite der Bogen zugeordnet sein. Die Installation erfolgt hier direkt in den Bogenführungsblechen gegenüber dem Gegendruckzylinder. Die Elektroden können durch eine Unterbrechung der Blech-Bogenführung und Einsatz eines nichtleitenden Materials aus beispielsweise Kunststoff oder Keramik, in das die Elektrode eingebettet wird, installiert werden. Der Gegendruckzylinder dient als Gegenelektrode und muss dementsprechend elektrisch geschaltet werden (Erdung).The drying device according to the invention can also be assigned between the printing units within the sheet guide, the recto printing side of the sheet. The installation takes place here directly in the sheet guide plates opposite the impression cylinder. The electrodes may be installed by interrupting sheet metal sheet guiding and by using a non-conductive material such as plastic or ceramic in which the electrode is embedded. Of the Counter-pressure cylinder serves as a counter electrode and must accordingly be switched electrically (earthing).

Weiterhin ist die erfindungsgemäße Trocknereinrichtung einsetzbar zwischen den Druckwerken in der Bogenführung auf der Widerdruckseite. Bei Wende- und Widerdruckbetrieb können in den Gegendruckzylinder 180° versetzt zwei Kanäle eingefügt werden, in denen die Elektrode, von nichtleitendem Material umgeben, eingebettet wird. Die Gegenelektrode befindet sich dann in einer nichtleitenden Einbettung in der Bogenführung. Der Abstand Elektrode - Bogen kann hier, je nach Anwendungsfall, genau eingestellt werden.Furthermore, the drying device according to the invention can be used between the printing units in the sheet guide on the reverse side. In reverse and reverse printing two channels can be inserted into the impression cylinder offset 180 °, in which the electrode, surrounded by non-conductive material, is embedded. The counter electrode is then in a non-conductive embedding in the sheet guide. The distance electrode - arc can be set exactly here, depending on the application.

Weiterhin ist eine Installation zwischen den Lackwerken in der Bogenführung auf der Schöndruckseite möglich. Die Installation erfolgt in diesem Falle wie im Falle der Installation zwischen den Druckwerken.Furthermore, an installation between the coating units in the sheet guide on the recto printing side is possible. In this case, the installation is carried out as in the case of installation between the printing units.

Ebenfalls ist es möglich, die erfindungsgemäße Trocknereinrichtung als feststehende Einrichtung in einer Auslegertrommel bzw. einer Bogenführungstrommel anzuordnen. Der über die Ausleger- bzw. Bogenführungstrommel geförderte Bogen wird dann mit der Ionenstrahlung der Elektrode beaufschlagt und, da die Elektrode feststeht und der Bogen sich bewegt, von diesem streifenförmig überstrichen.It is also possible to arrange the drying device according to the invention as a fixed device in a delivery drum or a sheet guiding drum. The sheet conveyed via the delivery or sheet guiding drum is then subjected to the ion radiation of the electrode and, since the electrode is stationary and the sheet moves, it is swept by it in the form of a strip.

Wie bei einer Installation zwischen den Druckwerken, wobei die Bogen auf der Widerdruckseite zu trocknen sind, kann die erfindungsgemäße Trocknungseinrichtung auch zwischen zwei oder mehreren Lackwerken entsprechend erfolgen.As with an installation between the printing units, wherein the sheets are to be dried on the reverse side, the drying device according to the invention can also be carried out accordingly between two or more coating units.

Letztlich sind auch Installationen zwischen dem letzten Druckwerk und dem Ausleger sowie innerhalb des Auslegers bis zum Auslegerstapel möglich. Durch entsprechende Aufhängung der erfindungsgemäßen Trocknereinrichtung statisch bzw. entsprechend der Bogenbewegung beweglich können die Bogen sowohl auf der Schön- als auch auf der Widerdruckseite getrocknet werden.Finally, installations between the last printing unit and the boom and within the boom to the delivery pile are possible. By appropriate suspension the drying device according to the invention static or movable according to the sheet movement, the sheets can be dried both on the recto and on the reverse side.

About gripper systems 10, the sheets are fed from the pick-up drum 9 to the delivery pile.

Den Transfertrommeln 1 sind die Bogen über die Widerdruckseite stützende Bogenführungen 11 zugeordnet. Weiterhin ist der Abnahmetrommel 9 eine Bogenführung 12 zugeordnet. Bei den Bogenführungen 11, 12 kann es sich um mit Saug- und/oder Blasluft beaufschlagbaren Bogenführungsblechen, Bogenführungsstäbe oder dergleichen handeln.The transfer drums 1, the arc on the counterpressure side supporting sheet guides 11 are assigned. Furthermore, the take-off drum 9 is associated with a sheet guide 12. The sheet guides 11, 12 may be with suction and / or Blasluft acted sheet guide plates, sheet guide rods or the like act.

Figur 2 zeigt die vorzugsweise bei der Erfindung vorzusehenden Komponenten der Trocknereinrichtung. Ein Bogen B bewegt sich in Richtung des Pfeiles. Die Trocknereinrichtung T besteht aus einem vorzugsweise als IR-Strahler ausgebildeten Strahler SL, in Bogenlaufrichtung diesem nachgeordnet einer den Bogen B mit diffuser Warmluft beaufschlagenden Blaseinrichtung TL, einer in Figur 2 nur prinzipiell dargestellten Elektrode E sowie einer dem vorgenannten Einrichtungen in Bogenlaufrichtung nachgeordneten Absaugeinrichtung S. FIG. 2 shows the preferably provided in the invention components of the dryer device. A bow B moves in the direction of the arrow.

Gemäß Figur 3 ist die Elektrode E mit einer Hochspannungsquelle HV verbunden. Diese ist ihrerseits mit einer Steuerung SHV verbunden, so dass die Zeitpunkte und die Höhe der Spannungsbeaufschlagung der Elektrode E gezielt durch die Steuerung SHV auslösbar sind. Die Steuerung SHV für die Elektrode E steht mit der Maschinensteuerung SM in Signalverbindung, was durch die Leitungen angedeutet ist. Die Maschinensteuerung SM weist ihrerseits einen Winkelgeber WG auf, der insbesondere an einer eintourig laufenden Welle befestigt ist. Durch die Signale des Winkelgebers sind über die Maschinensteuerung SM und die Steuerung der Hochspannungsquelle SHV die Zeitpunkte für die Spannungsbeaufschlagung der Elektrode E an einem vorgegebenen Einbauort ermittelbar. Insbesondere ist durch die Signale des Winkelgebers WG ermittelbar, wann ein Greifersystem im Förderweg 10 des Auslegers die Elektrode E passiert, demzufolge ein der Elektrode E zugeordnetes Stellglied die Elektrode E abzuheben hat. Weiterhin ist durch die Signale des Winkelgebers WG die Hochspannungsquelle HV so steuerbar, dass der Bogen B in Abhängigkeit der Druckgeschwindigkeit und seiner Länge mit dem geforderten und das Trocknungsverhalten positiv beeinflussenden Ionenstrom beaufschlagt wird. Auch der Abstand der Elektrode E zum Bogen bzw. der in Fig. 3 nicht dargestellten Gegenelektrode kann entsprechend vorgegebener Werte durch die Steuerung SHV erfolgen.According to FIG. 3 the electrode E is connected to a high voltage source HV. This is in turn connected to a controller SHV, so that the times and the amount of voltage applied to the electrode E are specifically triggered by the controller SHV. The controller SHV for the electrode E is in signal communication with the machine controller SM, which is indicated by the lines. The machine control SM in turn has an angle transmitter WG, which is fastened in particular to a single-speed shaft. By the signals of the angle encoder, the times for the voltage application of the electrode E at a predetermined installation location can be determined via the machine control SM and the control of the high voltage source SHV. In particular, it can be determined by the signals of the angle transmitter WG when a gripper system passes through the electrode E in the delivery path 10 of the delivery arm, according to which an electrode E associated with the actuator has to lift the electrode E. Furthermore, the high-voltage source HV can be controlled by the signals of the angle sensor WG so that the sheet B acts as a function of the printing speed and its length with the required and the drying behavior positively influencing ion current becomes. Also, the distance of the electrode E to the bow or in Fig. 3 counter-electrode, not shown, can be performed by the controller SHV according to predetermined values.
