The offset printer drier has a controller (12) to activate radiant and hot air nozzle heaters (2,3), cooler heat exchanger (6) and temperature sensors (13). The drier further comprises an air extraction (10) with control flap (11) to achieve more rapid rise to operating temperature.

Description

Die Erfindung betrifft einen Trockner für eine Druckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a dryer for a printing press according to the preamble of claim 1.

[Stand der Technik][State of the art]

Zum Trocknen von mit Lösungsmittel enthaltenden Druckfarben bedruckter Bogen werden bei Bogenoffsetdruckmaschinen meist IR-Trockner verwendet. Diese Trocknereinrichtungen sind zwischen den Druckwerken bzw. zwischen dem letzten Druckwerk und dem Ausleger angeordnet. Ein oder mehrere IR-Strahler sind dazu einer Bogenführungsbahn zugeordnet. Zusätzlich sind auch Heißluftdüsen vorgesehen. Zum Abführen der ausgetriebenen Lösungsmitteldämpfe ist der Trocknereinrichtung eine Abluftabsaugeinrichtung zugeordnet. Um zu hohe Temperaturen im Bereich der Bogenführung zu vermeiden, ist es ferner bekannt, die Bogenführungsbahn mit einer Kühleinrichtung auszustatten. Dazu strömt Kühlflüssigkeit durch Kanäle in der Bogenführungsbahn - die aufgenommene Wärme wird über einen Wärmetauscher abgegeben. Einrichtungen dieser Art sind beispielsweise aus der DE 44 38 922 A1 oder der EP 0 641 653 B1 bekannt.IR dryers are mostly used in sheetfed offset printing presses to dry sheets printed with solvents. These dryer devices are arranged between the printing units or between the last printing unit and the delivery. For this purpose, one or more IR emitters are assigned to a sheet guideway. In addition, hot air nozzles are also provided. An exhaust air extraction device is assigned to the dryer device to remove the expelled solvent vapors. In order to avoid excessively high temperatures in the area of the sheet guide, it is also known to equip the sheet guide path with a cooling device. For this purpose, coolant flows through channels in the sheet guideway - the heat absorbed is released via a heat exchanger. Devices of this type are known for example from DE 44 38 922 A1 or EP 0 641 653 B1.

Bei Produktionsbeginn bzw. nach Druckunterbrechungen (z.B. Stopper) sind die geschilderten Einrichtungen derartig anzusteuern, so dass ein Überhitzen der entsprechenden Komponenten bzw. beteiligten Maschinenteile vermieden wird. Eine Überhitzungsgefahr während Maschinenstillstand besteht insbesondere deswegen, da keine Luftbewegung und auch kein Wärmetransport durch den Bedruckstoff vorliegt. Andererseits ist zu gewährleisten, dass ein Papierlauf mit anschließendem auf Druck-Schalten erst dann gegeben wird, wenn die nötige Betriebstemperatur erreicht ist.At the start of production or after pressure interruptions (eg stoppers), the devices described should be controlled in such a way that overheating of the corresponding components or machine parts involved is avoided. There is a risk of overheating during machine downtime, in particular because there is no air movement and no heat transport through the printing material. On the other hand, it must be ensured that a paper run with subsequent pressure switching is only given when the necessary operating temperature has been reached.

Die DE 42 07 071 A1 beschreibt ein Regelsystem für Rollenrotationsdruckmaschinen, wobei diese einen thermischen Trockner aufweist, dem eine Verbrennungsanlage nachgeschaltet ist. Die Geschwindigkeit der Rotationsdruckmaschine ist durch das Temperaturänderungsverhalten des Abgases in der Verbrennungsanlage regelbar.DE 42 07 071 A1 describes a control system for web-fed rotary printing presses, which has a thermal dryer which is followed by an incinerator. The speed of the rotary printing press can be regulated by the temperature change behavior of the exhaust gas in the combustion system.

Aus der DE 43 09 266 A1 ist ein Verfahren zur Steuerung der Einschaltung des Papierlaufes einer Druckmaschine mit Trockner bekannt. Um zu erreichen, dass der Bedruckstoff erst dann in die Maschine einläuft, wenn der Trockner die optimalen Betriebsbedingungen erreicht hat, erfolgt das Ansteuern des Antriebes für den Papierlauf bzw. den Druck zeitverzögert gegenüber dem Anschalten des Trockners. Dadurch wird vermieden, dass Bedruckstoff in die Maschine einläuft, wenn der nachgeordnete Trockner nicht den vorgesehenen Betriebsbereich erreicht hat und die verdruckten Farben nicht vollständig austrocknen können. Nachteil ist es hierbei aber, dass dabei unter Umständen erhebliche Zeitspannen anfallen.DE 43 09 266 A1 discloses a method for controlling the switching on of the paper path of a printing press with dryer. In order to ensure that the printing material does not run into the machine until the dryer has reached the optimum operating conditions, the drive for the paper feed or the printing is triggered with a time delay compared to the switching on of the dryer. This prevents the substrate from running into the machine if the downstream dryer has not reached the intended operating range and the printed inks cannot dry out completely. The disadvantage here, however, is that there may be considerable periods of time.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Aufgabe der vorliegenden Erfindung ist es daher, einen Trockner gemäß dem Oberbegriff von Anspruch 1 derartig weiterzubilden, so dass die Betriebstemperatur schneller erreicht werden kann.The object of the present invention is therefore to develop a dryer in accordance with the preamble of claim 1 in such a way that the operating temperature can be reached more quickly.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildung der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further development of the invention result from the subclaims.

[Beispiele][Examples]

Gemäß der Erfindung ist vorgesehen, dass durch die Steuerung vor Druckbeginn wenigstens eine Einrichtung zeitweise mit Werten zur Erzeugung einer höheren als für den Druck vorgesehenen Temperatur ansteuerbar ist.According to the invention it is provided that at least one device can be controlled temporarily with values for generating a higher temperature than that provided for the pressure by the control before the start of printing.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die durch die Steuerung mehrere Einrichtungen in entsprechender Weise angesteuert werden, so dass sich eine noch stärkere Verkürzung der Vorheizzeit von dem Trockner ergibt.According to a preferred development of the invention, it is provided that the multiple devices are controlled in a corresponding manner by the control, so that the preheating time of the dryer is reduced even more.

Erfindungsgemäß kann dazu vorgesehen sein, dass die IR-Heizstäbe kurzzeitig mit einer erhöhten Leistung angesteuert werden. Die Heizeinrichtung von Heizluftdüsen zur Beaufschlagung des Bedruckstoffes mit Heißluft kann ebenfalls für eine vorgesehene Zeitspanne mit einer erhöhten Leistung betrieben werden. So erreichen sowohl die Zuführleitungen zu den entsprechenden Düsen als auch die entsprechenden Düsen selbst in möglichst kurzer Zeit ihre Betriebstemperatur - gleiches gilt für die austretende Luft.According to the invention, it can be provided that the IR heating elements are briefly activated with an increased output. The heating device of hot air nozzles for applying hot air to the printing material can also be operated with increased power for a specified period of time. In this way, both the supply lines to the corresponding nozzles and the corresponding nozzles themselves reach their operating temperature in the shortest possible time - the same applies to the emerging air.

Weist die Trocknereinrichtung eine wassergekühlte Bogenführungsbahn auf, so kann vorgesehen sein, zur Verkürzung der Aufheizzeit zumindest das Kühlsystem zeitweise abzuschalten. Weiterbildend kann dabei vorgesehen sein, nicht nur das Kühlsystem abzuschalten, sondern auch auf Heizung umzuschalten, d.h. durch aufgeheiztes Wasser die Bogenführungsbahn schneller in den Bereich der vorgesehenen Temperatur zu verbringen.If the dryer device has a water-cooled sheet guideway, it can be provided that at least the cooling system is temporarily switched off to shorten the heating-up time. In a further development it can be provided not only to switch off the cooling system, but also to switch to heating, i.e. through heated water to spend the sheet guideway faster in the range of the intended temperature.

Weist die Trocknereinrichtung eine Absaugeinrichtung zur Abfuhr der austretenden Lösungsmitteldämpfe auf, so kann vorgesehen sein, dass in einer Vorheizphase die Absaugung abgeschaltet bzw. für einen vorgesehenen Zeitraum die Abluftklappe geschlossen wird. So wird verhindert, dass durch Abtransport von Luft ebenfalls Energie aus der Trocknereinrichtung gefördert wird.If the dryer device has a suction device for removing the escaping solvent vapors, it can be provided that the suction is switched off in a preheating phase or the exhaust air flap is closed for a specified period of time. This prevents energy from being conveyed out of the dryer by removing air.

Des weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung anhand der Zeichnung. Diese zeigt prinzipiell die Einrichtungen bei einer Trocknereinrichtung.Furthermore, an embodiment of the invention is explained with reference to the drawing. In principle, this shows the facilities of a dryer facility.

Die Trocknereinrichtung einer nicht weiter dargestellten Bogenoffsetdruckmaschine weist eine wassergekühlte Bogenführungsbahn 1 auf. Die Förderrichtung der Bogen über diese Bogenführungsbahn 1 durch den Pfeil angedeutet.The dryer device of a sheetfed offset printing press, not shown, has a water-cooled sheet guideway 1. The direction of conveyance of the sheets via this sheet guideway 1 is indicated by the arrow.

Oberhalb der Bogenführungsbahn 1 sind Heizstrahler (IR-Strahler) 2 sowie Heißluftdüsen 3 angeordnet. Die Bogen werden zwischen den Strahlern 2, den Heißluftdüsen 3 und der Bogenführungsbahn 1 hindurch gefördert.Radiant heaters (IR radiators) 2 and hot air nozzles 3 are arranged above the sheet guideway 1. The sheets are conveyed between the radiators 2, the hot air nozzles 3 and the sheet guideway 1.

Die Heizstrahler 2 stehen mit einer Steuerung 4, die Heißluftdüsen 3 mit einer Steuerung 5 in Verbindung. Durch die Steuerungen 4, 5 erfolgt die elektrische bzw. pneumatische Beaufschlagung der jeweiligen Einrichtungen.The radiant heaters 2 are connected to a controller 4, the hot air nozzles 3 to a controller 5. The controls 4, 5 provide the electrical or pneumatic loading of the respective devices.

Die Bogenführungsbahn 1 steht mit einem Wärmetauscher 6 über einen Zulauf 7 sowie Rücklauf 8 in Verbindung. Weiterhin ist im Zulauf 7 ein Mischventil 9 vorgesehen, durch welches im Rücklauf 8 befindliches Kühlwasser direkt zurück in die Bogenführungsbahn 1 gefördert werden kann.The sheet guideway 1 is connected to a heat exchanger 6 via an inlet 7 and a return 8. Furthermore, a mixing valve 9 is provided in the inlet 7, through which cooling water located in the return 8 can be conveyed directly back into the sheet guideway 1.

Oberhalb der Bogenführungsbahn 1 ist eine Ablaufsaugeinrichtung 10 angeordnet, welche eine Ablaufklappe 11 aufweist. Die Abluftabsaugeinrichtung 10 ist prinzipiell angeordnet, und umschließt die genannten Einrichtungen.A drain suction device 10, which has a drain flap 11, is arranged above the sheet guideway 1. The exhaust air suction device 10 is arranged in principle and encloses the devices mentioned.

Auf der Bogenführungsbahn 1 ist ein Temperatursensor 13 angebracht, durch welchen der mit ihm in Signalverbindung stehenden Steuerung 12 der Temperatur entsprechende Signale zuführbar sind. Die Steuerung 12 steht ferner mit der Steuerung 4 für die Heizstrahler 2, der Steuerung 5 für die Heißluftdüsen 3, dem Wärmetauscher 6 der Bogenführungsbahn 1, dem Mischventil 9 im Zulauf der Bogenführungsbahn 1 sowie der Abluftklappe 11 der Abluftabsaugeinrichtung 10 in Signalverbindung. Durch die Steuerung 12 werden den genannten Einrichtungen derartige Signale zugestellt, so dass die für den Druckbetrieb vorgesehenen Temperaturbereiche erreicht werden. Dazu wird insbesondere der Signalwert des Temperatursensors 13 im Sinne einer Regelung ausgewertet.A temperature sensor 13 is mounted on the sheet guideway 1, by means of which signals corresponding to the temperature can be supplied to the controller 12 in signal connection with it. The controller 12 also stands with the controller 4 for the radiant heater 2, the controller 5 for the hot air nozzles 3, the heat exchanger 6 of the sheet guideway 1, the mixing valve 9 in the inlet of the sheet guideway 1 and the exhaust air flap 11 of the exhaust air suction device 10 in signal connection. The controller 12 sends such signals to the devices mentioned, so that the temperature ranges provided for the printing operation are reached. For this purpose, in particular the signal value of the temperature sensor 13 is evaluated in the sense of a regulation.

Um nach einer Druckunterbrechung vor Druckbeginn die Einrichtungen des Trockners schnellstmöglich auf den vorgesehenen Temperaturwert zu verbringen, erfolgt durch die Steuerung 12 eine entsprechende Signalabgabe an die Steuerung 4 für die Heizstrahler 2, und/oder die Steuerung 5 für die Heißluftdüsen 3, und/oder den Wärmetauscher 6 bzw. das Mischventil 9 der Bogenführungsbahn 1, und/oder die Abluftklappe 11 der Abluftabsaugeinrichtung 10 in der Weise, dass kurzzeitig eine stärkere als für den Druckbetrieb vorgesehene Erwärmung erfolgt .In order to bring the devices of the dryer to the intended temperature value as quickly as possible after a pressure interruption before the start of printing, the controller 12 issues a corresponding signal to the controller 4 for the radiant heaters 2, and / or the controller 5 for the hot air nozzles 3, and / or Heat exchanger 6 or the mixing valve 9 of the sheet guideway 1, and / or the exhaust air flap 11 of the exhaust air extraction device 10 in such a way that there is briefly greater heating than is provided for the printing operation.

Dabei ist insbesondere vorgesehen, dass durch die Steuerung 4 für die Heizstrahler 2 diese stärker bestromt werden, also in kürzester Zeit die vorgesehene Heizleistung erreichen. Weiterhin ist vorgesehen, dass durch die Steuerung 12 und eine entsprechende Signalabgabe die Heißluftdüsen 3 mit stärker erhitzter Heißluft beaufschlagt werden, was durch die vorgeordnete Steuerung 5 bewirkt wird.In particular, it is provided that the controller 4 for the radiant heaters 2 energizes them more intensively, that is, they reach the intended heating output in the shortest possible time. It is further provided that the controller 12 and a corresponding signal output act on the hot air nozzles 3 with more heated hot air, which is brought about by the upstream controller 5.

Weiterhin ist vorgesehen, die Bedruckstoffführung 1 durch den Wärmetauscher 6 aufzuheizen, was durch Schalten des Mischventils 9 erfolgen kann, d.h. die für den eigentlichen Druckbetrieb vorgesehene Kühlung wird entsprechend geschwächt bzw. ganz abgeschaltet.It is also provided that the printing material guide 1 is heated by the heat exchanger 6, which can be done by switching the mixing valve 9, ie the cooling provided for the actual printing operation is correspondingly weakened or completely switched off.

Letztlich ist auch ein kurzzeitiges Schließen der Abluftklappe 11 vorgesehen, so dass durch den kurzzeitig unterbundenen Luftabtransport ein stärkeres Aufheizen des Innenraumes der Abluftabsaugung 10 somit der gesamten Trockner Einrichtung erfolgt .Ultimately, a short-term closing of the exhaust air flap 11 is also provided, so that the air transport, which is briefly prevented, results in the interior of the exhaust air extraction 10 being heated up to a greater extent, thus the entire dryer device.

Nachdem die Einrichtung mit dem Trockner die vorgesehene Temperatur erreicht hat, erfolgt das Zuschalten des Bogenlaufes sowie das Schalten der Druckzylinder auf Druck-An. Die Steuerung 12 steht dazu mit der Steuerung der nicht dargestellten Druckmaschine in Signalverbindung.After the device with the dryer has reached the intended temperature, the sheet travel is switched on and the printing cylinders are switched to print on. The controller 12 is in signal connection with the controller of the printing press, not shown.
