Description

Die Erfindung betrifft eine Maschine zum Herstellen von Druckprodukten mit den Merkmalen von Anspruch 1.The invention relates to a machine for producing printed products with the features of claim 1.

Technisches Gebiet und Stand der TechnikTechnical field and state of the art

Die Erfindung liegt auf dem technischen Gebiet der grafischen Industrie und dort insbesondere im Bereich des industriellen, d.h. hochproduktiven Tintendrucks (InkJet) auf flache Substrate, d.h. des Auftragens und (Wärme-) Trocknens von flüssiger, bevorzugt wasserbasierter Tinte, auf bogen- oder bahnförmige Bedruckstoffe, bevorzugt aus Papier, Karton, Pappe, Kunststoff oder Verbundmaterial.The invention lies in the technical field of the graphics industry and there in particular in the field of industrial, i.e. highly productive inkjet printing on flat substrates, i.e. the application and (heat) drying of liquid, preferably water-based ink, onto sheet or web-like printing materials, preferably made of paper, cardboard, cardboard, plastic or composite material.

Das Auftragen flüssiger Tinte erfolgt bei dem bekannten DOD-Tintendruckverfahren (drop-on-demand), indem ein Druckbild auf einem flachen Bedruckstoff erzeugt wird, wobei ein Tintendruckkopf (kurz: Kopf) mit einzeln ansteuerbaren Düsen dem zu druckenden Bild entsprechend feinste Tintentropfen, bevorzugt im Pikoliter-Bereich, erzeugt und diese berührungslos als Druckpunkte auf den Bedruckstoff überträgt. Das Ansteuern der Düsen kann mittels Piezoaktoren erfolgen.The application of liquid ink takes place in the known DOD ink printing process (drop-on-demand), in which a print image is generated on a flat printing material, an ink print head (head for short) with individually controllable nozzles corresponding to the image to be printed, preferably the finest ink drops in the picolitre range, and transfers them to the substrate as pressure points without contact. The nozzles can be controlled using piezo actuators.

Ein ausreichendes thermisches Trocknen wasserbasierter Tinten auf dem bewegten Bedruckstoff, d.h. insbesondere das dafür erforderliche Verdunsten von Wasser, erfordert einen Trockner zur Erzeugung einer hohen räumlichen Leistungsdichte, welcher alles überschüssige Wasser in der kurzen Verweilzeit des Bedruckstoffs im Wirkbereich des Trockners verdampft. Es erfolgt daher im Bereich des Trockners ein hoher Energieeintrag in die Maschine. Infolgedessen kann es zu einer unerwünschten Wärmeausdehnung von Maschinenteilen, wie z.B. Seitenwänden oder Zylindern, kommen. Solche Wärmeausdehnungen können sich störend auf den Druckprozess auswirken.Sufficient thermal drying of water-based inks on the moving substrate, ie in particular the evaporation of water required for this, requires a dryer to generate a high spatial power density, which evaporates all excess water in the short dwell time of the substrate in the effective area of the dryer. There is therefore a high input of energy into the machine in the area of the dryer. This can lead to undesirable thermal expansion of machine parts such as side walls or cylinders. Such thermal expansions can interfere with the printing process.

Der Tintendruck mit wasserbasierten Tinten (Wasser als Lösungsmittel der Tinte) erfordert einen Druckprozess bei im Wesentlichen konstanter Temperatur. Der Wärmeeintrag eines vorhandenen Trockners in die Druckmaschine kann daher leicht zu wahrnehmbaren Störungen des Druckprozesses führen.Ink printing with water-based inks (water as the solvent for the ink) requires a printing process at a substantially constant temperature. The heat input from an existing dryer into the printing press can therefore easily lead to noticeable disruptions in the printing process.

Die Kühlung eines bogenförmigen Zylinders in einer Inkjet-Druckmaschine ist bereits aus der DE 20 2018 000 418 U1 bekannt. Dort ist unterhalb des bogenführenden Zylinders eine Blaseinrichtung angeordnet, welche zugleich diesen Zylinder und eine, diesem vorgeordnete, Trommel bzw. den von ihr geführten Bogen temperiert.The cooling of an arched cylinder in an inkjet printing machine is already out of the question DE 20 2018 000 418 U1 known. There, a blowing device is arranged below the sheet-guiding cylinder, which at the same time temperature-regulates this cylinder and an upstream drum or the sheet guided by it.

Die DE 11 2015 004 269 T5 offenbart eine ähnliche Vorrichtung. Die DE 103 34 657 A1 offenbart ebenfalls eine ähnliche Vorrichtung, jedoch nicht in einer Inkjet-Druckmaschine.The DE 11 2015 004 269 T5 discloses a similar device. The DE 103 34 657 A1 also discloses a similar device, but not in an inkjet printing machine.

Die FR 2 734 758 offenbart eine Kühleinrichtung zum Kühlen eines Zylinders, wobei die Einrichtung hinsichtlich ihrer Formgebung an die zu kühlende zylindrische Oberfläche angepasst ist.The FR 2 734 758 discloses a cooling device for cooling a cylinder, the device being adapted in terms of its shape to the cylindrical surface to be cooled.

Solche Kühleinrichtungen erreichen oft nicht die erforderliche Kühlleistung, insbesondere bei sehr hohem Wärmeeintrag durch zum Druckwerk benachbarte Wärmetrockner. Üblicherweise wird diesem Problem begegnet, indem der Volumenstrom und/oder die Kühlleistung erhöht wird/werden. Beide Maßnahmen erhöhen jedoch auch die Kosten durch das Vorsehen weiterer Gebläse und weiterer Wärmetauscher. Der Markt fordert daher beständig weitere Maßnahmen für eine verbesserte und kostensparende Kühlung.Such cooling devices often do not achieve the required cooling capacity, in particular when there is a very high heat input from heat dryers adjacent to the printing unit. This problem is usually countered by increasing the volume flow and / or the cooling capacity. However, both measures also increase the costs through the provision of additional fans and additional heat exchangers. The market is therefore constantly demanding further measures for improved and cost-saving cooling.

Die EP 0 658 427 B1 zeigt keine Einrichtung zum Kühlen, sondern einen Wärmetrockner; dieser ist nach dem sogenannten Prallstrahl-Prinzip konzipiert.The EP 0 658 427 B1 shows no device for cooling, but a heat dryer; this is designed according to the so-called impact jet principle.

Aufgabetask

Es ist somit eine Aufgabe der vorliegenden Erfindung, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zu schaffen, welche es insbesondere ermöglicht, eine für einen ungestörten Druckprozess ausreichende Kühlung zu erwirken und dabei Kosten niedrig zu halten oder Kosten einzusparen.It is therefore an object of the present invention to create a device which is improved over the prior art and which in particular enables a for to achieve sufficient cooling for an undisturbed printing process while keeping costs down or saving costs.

Erfindungsgemäße LösungSolution according to the invention

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit der Merkmalskombination von Anspruch 1 gelöst. Vorteilhafte und daher bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung und den Zeichnungen. Die Merkmale der Erfindung, der Weiterbildungen der Erfindung und der Ausführungsbeispiele zur Erfindung stellen auch in Kombination miteinander vorteilhafte Weiterbildungen der Erfindung dar.According to the invention, this object is achieved by a device with the combination of features of claim 1. Advantageous and therefore preferred developments of the invention emerge from the subclaims and from the description and the drawings. The features of the invention, the developments of the invention and the exemplary embodiments of the invention also represent advantageous developments of the invention in combination with one another.

Eine erfindungsgemäße Maschine zum Herstellen von Druckprodukten, mit einer Druckeinrichtung zum Bedrucken eines Bedruckstoffs, insbesondere einer Tinten-Druckeinrichtung (InkJet), einem Trockner zum Trocknen des bedruckten Bedruckstoffs, insbesondere einem Wärmetrockner, einer Transporteinrichtung zum Transportieren des Bedruckstoffs, insbesondere einem Zylinder, und einer Blaseinrichtung zum Kühlen der Transporteinrichtung, zeichnet sich dadurch aus, dass die Blaseinrichtung als eine Prallstrahl-Blaseinrichtung ausgebildet ist.A machine according to the invention for producing printed products, with a printing device for printing a printing material, in particular an ink printing device (InkJet), a dryer for drying the printed printing material, in particular a heat dryer, a transport device for transporting the printing material, in particular a cylinder, and a Blower device for cooling the transport device is characterized in that the blower device is designed as an impact jet blower device.

Die Erfindung ermöglicht es in vorteilhafter Weise, eine für einen ungestörten Druckprozess ausreichende Kühlung zu erwirken und dabei die Kosten niedrig zu halten oder Kosten einzusparen.The invention makes it possible in an advantageous manner to achieve sufficient cooling for an undisturbed printing process while keeping costs low or saving costs.

Erfindungsgemäß wird eine Prallstrahl-Blaseinrichtung eingesetzt. Mit dieser kann eine sogenannte Nahfeld-Kühlung erwirkt werden. Eine solche Kühlung kann eine bis zum Faktor 5 verbesserte Kühlleistung gegenüber einer Blaseinrichtung mit einem offenen Blaskasten erreichen. Bei Einsatz des so genannten Prallstrahlprinzips zur Kühlung der Transporteinrichtung wird die Transporteinrichtung mit Blasluft mit hoher Geschwindigkeit, z.B. 50 bis 90 m/s, und gleichzeitig niedrigem Volumenstrom, z.B. 300 bis 3000 m3/h, beaufschlagt. Die Prallstrahl-Blaseinrichtung wird bevorzugt nahe an der zu kühlenden Transporteinrichtung angeordnet, z.B. im Abstand von 3 bis 30 mm. Der Luftauslass aus der Prallstrahl-Blaseinrichtung erfolgt bevorzugt durch eine Vielzahl von kleinen Öffnungen oder Düsen, anstelle aus einer einzigen, großen Öffnung der Blaseinrichtung, z.B. mit einem Durchmesser von 0,5 bis 5 mm.According to the invention, an impact jet blowing device is used. This enables so-called near-field cooling to be achieved. Such cooling can achieve a cooling performance which is up to a factor of 5 compared to a blower device with an open blow box. When using the so-called impact jet principle to cool the transport device, the transport device is subjected to blown air at high speed, for example 50 to 90 m / s, and at the same time a low volume flow, for example 300 to 3000 m 3 / h. The impact jet blowing device is preferably arranged close to the transport device to be cooled, for example at a distance of 3 to 30 mm. Of the Air is preferably discharged from the impingement jet blowing device through a large number of small openings or nozzles, instead of from a single, large opening in the blowing device, for example with a diameter of 0.5 to 5 mm.

Die Erfindung bietet somit den Vorteil, dass ein niedriger Volumenstrom an Blasluft bereits ausreicht, um eine ausreichende Kühlung zu erwirken. Dadurch kann die Blaseinrichtung an eine bereits vorhandene Blasluft-Versorgungseinrichtung der Maschine angeschlossen werden. Dadurch wiederum können Kosteneinsparungen durch das Einsparen weiterer Gebläse und/oder weiterer Wärmetauscher erreicht werden.The invention thus offers the advantage that a low volume flow of blown air is already sufficient to achieve sufficient cooling. This allows the blowing device to be connected to an existing blowing air supply device of the machine. This in turn enables cost savings to be achieved by saving additional fans and / or additional heat exchangers.

Die Blaseinrichtung 6 ist erfindungsgemäß als eine Prallstrahl-Blaseinrichtung ausgebildet.The machine 1 comprises a printing device 3, preferably four or seven pressure bars each with a large number of inkjet print heads, a dryer, preferably an infrared dryer (IR) or hot air dryer (HL) or an IR-HL combination dryer or a UV dryer , a transport device 5, preferably a sheet-guiding drum or a conveyor belt, and a blower device 6 for cooling the transport device to preferably a process-related limit temperature with a tolerance of ± 2 ° Celsius. According to the invention, the blowing device 6 is designed as an impact jet blowing device.

Weiterhin umfasst die Maschine 1 eine Versorgungseinrichtung 7, z.B. ein sogenanntes Klima-Aggregat, welche über eine Leitung 8 für gekühlte Blasluft mit der Blaseinrichtung 6 in Verbindung steht. Die Versorgungseinrichtung steht ferner über eine Leitung 9 für gekühlte Blasluft mit einer weiteren Blaseinrichtung 10 der Maschine in Verbindung. Die weitere Blaseinrichtung dient bevorzugt dem Kühlen der Druckeinrichtung, zusätzlich oder alternativ dem Kühlen der Transporteinrichtung.The machine 1 further comprises a supply device 7, e.g. a so-called air conditioning unit, which is connected to the blowing device 6 via a line 8 for cooled blowing air. The supply device is also connected to another blowing device 10 of the machine via a line 9 for cooled blowing air. The further blower device is preferably used to cool the printing device, additionally or alternatively to cool the transport device.

Die Versorgungseinrichtung 7 umfasst einen Wärmetauscher 11 und ein Gebläse 12 zum Erzeugen gekühlter Blasluft und umfasst optional einen (nicht dargestellten) Filter zum Filtern der Blasluft. In der Leitung 8 kann ein weiteres Gebläse 13 und kann ein Ventil 14, z.B. ein sogenanntes Shutter-Ventil, vorgesehen sein. Das Gebläse 13 kann als ein Stützgebläse dienen, um den Strömungswiderstand der Blaseinrichtung 6 auszugleichen. Eine Drehrichtungsumkehr des Stützgebläses kann bevorzugt auch zum Abschalten der Blaseinrichtung 6 dienen, indem die Luftzufuhr erheblich reduziert oder verhindert wird.The supply device 7 comprises a heat exchanger 11 and a fan 12 for generating cooled blown air and optionally comprises a filter (not shown) for filtering the blown air. In the line 8 a further fan 13 and a valve 14, e.g. a so-called shutter valve may be provided. The blower 13 can serve as a support blower in order to compensate for the flow resistance of the blower device 6. A reversal of the direction of rotation of the support fan can preferably also be used to switch off the blower device 6 in that the air supply is significantly reduced or prevented.

Von dem Druck der Blasluft in der Versorgungseinrichtung 7 steht an der Blaseinrichtung 6 bevorzugt wenigstens etwa ein Fünftel zur Verfügung.At least approximately one fifth of the pressure of the blown air in the supply device 7 is preferably available at the blower device 6.

Figur 1 zeigt eine Steuereinrichtung 22, welche die Versorgungseinrichtung 7 und optional das weitere Gebläse 13 und das Ventil 14 ansteuert. Die Ansteuerung erfolgt bevorzugt nach der im Folgenden angegebenen Schaltlogik: Maschinenzustand weitere Blaseinrichtung 10 Blaseinrichtung 6 1. Standby (Nachtmodus) aus aus 2. Betrieb mit Bogentransport an an 3. Betrieb ohne Bogentransport an an 4. Maschinenstillstand ohne Bogen (Pause) an aus 5. Maschinenstillstand mit Bogen (Notstop) an aus 6. Köpfe über Trommel 5 (Reinigen der Inkjetköpfe) an aus 7. Ausfall des Klimaaggregats aus aus Figure 1 shows a control device 22 which controls the supply device 7 and optionally the further fan 13 and the valve 14. The control is preferably carried out according to the switching logic specified below: Machine condition further blowing device 10 Blower 6 1. Standby (night mode) out out 2. Operation with sheet transport at at 3. Operation without sheet transport at at 4. Machine standstill without sheets (pause) at out 5. Machine standstill with sheet (emergency stop) at out 6.Heads above drum 5 (cleaning the inkjet heads) at out 7. Failure of the air conditioning unit out out

Figur 1 zeigt ein optionales Luftschwert 23 zwischen der Trommel 5 und dem Trockner 4. Auch dieses Luftschwert kann an die Versorgungseinrichtung 7 angeschlossen sein. Das Schwert kann insbesondere bei stehender Maschine ein Erwärmen der Trommel durch den Trockner verhindern. Figure 1 shows an optional air sword 23 between the drum 5 and the dryer 4. This air sword can also be connected to the supply device 7. The sword can prevent the drum from heating up by the dryer, especially when the machine is at a standstill.

Die Blaseinrichtung 6 ist in Figur 2 deutlicher, in perspektivischer Darstellung dargestellt. Die Blaseinrichtung 6 umfasst einen sogenannten Nahfeldkühler 15 mit einem Kühlkasten 16 zum Ausstoßen der gekühlten Blasluft. Der Kühlkasten weist eine Oberfläche 17 mit einer Vielzahl an Öffnungen auf, z.B. Bohrungen 18, welche als Düsen 18 wirken. Die Oberfläche kann eine (der Trommel 5) angepasste und daher bevorzugt konkave Krümmung aufweisen. Beispielsweise kann die Oberfläche als ein Blech ausgebildet sein. Das Blech kann in einem konkreten Beispiel mehr als 10 mal 30, d.h. 300 Bohrungen, z.B. zwischen 1.000 und 2.0000 Bohrungen, aufweisen. Jede Bohrung kann z.B. einen Durchmesser zwischen 1,5 und 3,0 mm haben.The blower 6 is in Figure 2 more clearly, shown in perspective. The blowing device 6 comprises a so-called near field cooler 15 with a cooling box 16 for ejecting the cooled blowing air. The cooling box has a surface 17 with a multiplicity of openings, for example bores 18, which act as nozzles 18. The surface can have a curvature adapted to (the drum 5) and therefore preferably concave. For example, the surface can be designed as a sheet metal. In a specific example, the sheet metal can have more than 10 by 30, ie 300 bores, for example between 1,000 and 2,000 bores. Each hole can, for example, have a diameter between 1.5 and 3.0 mm.

Der Nahfeldkühler ist mit einem geringen Abstand 19 (vgl. Figur 3) zur Oberfläche der Trommel 5 angeordnet, bevorzugt mit einem Abstand von etwa 10 mm.The near-field cooler is at a small distance 19 (cf. Figure 3 ) arranged to the surface of the drum 5, preferably at a distance of about 10 mm.

Das Verhältnis zwischen Düsendurchmesser, Anordnung der Düsen (bzw. deren gegenseitiger Abstand) und Abstand der Düsen zur Trommel ist in dem zuvor genannten Beispiel und in Alternativen dazu bevorzugt so gewählt, dass ein ausreichend kühlender Blasluftstrom zur Oberfläche der Trommel gelangt.The relationship between the nozzle diameter, the arrangement of the nozzles (or their mutual spacing) and the distance between the nozzles and the drum is preferably selected in the aforementioned example and in alternatives to this so that a sufficiently cooling blown air flow reaches the surface of the drum.

Mittels der Düsen 18 der Blaseinrichtung 6 wird (durch deren Lufteinlasse 20 zugeführte) gekühlte Blasluft mit einer hohen Austrittsgeschwindigkeit, von z.B. 15 bis 90 m/s zur Oberfläche der Trommel 5 geblasen ("Prallstrahl-Prinzip"), wodurch eine Grenzschicht auf der Oberfläche der Trommel effektiv durchstoßen wird und folglich ein effizientes Kühlen der Trommel erreicht wird.By means of the nozzles 18 of the blower device 6, cooled blown air (supplied through its air inlets 20) is supplied with a high exit speed, e.g. 15 to 90 m / s to the surface of the drum 5 ("impingement jet principle"), whereby a boundary layer on the surface of the drum is effectively pierced and consequently an efficient cooling of the drum is achieved.

Figur 3 zeigt einen Querschnitt durch eine Blaseinrichtung 6. Deutlich sind die konkav gekrümmte Oberfläche 17 und deren geringer Abstand 19 zur Oberfläche 5a der Trommel 5 zu erkennen. Die Blaseinrichtung ist in ihrem Innern im Wesentlichen leer. Figure 3 shows a cross section through a blowing device 6. The concavely curved surface 17 and its small distance 19 from the surface 5a of the drum 5 can be clearly seen. The interior of the blower is essentially empty.

Die in Figur 1 dargestellte Versorgungseinrichtung 7 stellt ausreichend Blasluft sowohl für die weitere Blaseinrichtung 10 als auch für die Blaseinrichtung 6 zur Verfügung. Da die Blaseinrichtung 6 nach dem Prallstrahl-Prinzip arbeitet und daher nur einen geringen Volumenstrom an Blasluft benötigt, wird die weitere Blaseinrichtung 10 bevorzugt mit hohem und die Blaseinrichtung 6 bevorzugt mit niedrigem Volumenstrom an Blasluft versorgt. Beispielsweise wird die Blaseinrichtung 6 mit 500 bis 1.000 m3/h blasluftversorgt. Beispielsweise wird die weitere Blaseinrichtung 10 mit 1.000 bis 2.000 m3/h blasluftversorgt Die Blaseinrichtung 6 kann daher bevorzugt an eine bereits vorhandene Versorgungseinrichtung 7 angeschlossen werden, ohne deren Versorgung der weiteren Blaseinrichtung 10 wesentlich einzuschränken. Hierdurch können Kosten eingespart werden. Zudem kann Bauraum eingespart werden.In the Figure 1 The supply device 7 shown provides sufficient blowing air both for the further blowing device 10 and for the blowing device 6. Since the blowing device 6 works according to the impact jet principle and therefore only requires a small volume flow of blowing air, the further blowing device 10 is preferably supplied with a high volume flow of blowing air and the blowing device 6 is preferably supplied with a low volume flow. For example, the blowing device 6 is supplied with blowing air with 500 to 1,000 m 3 / h. For example, the further blower device 10 is supplied with blowing air from 1,000 to 2,000 m 3 / h. The blower device 6 can therefore preferably be connected to an existing supply device 7 without significantly restricting its supply to the further blower device 10. This can save costs. In addition, installation space can be saved.

Da mehr Blasluft "von oben" (d.h. von der weiteren Blaseinrichtung 10) als "von unten" (d.h. von der Blaseinrichtung 6) in die Maschine gelangt, wird in vorteilhafter Weise verhindert, dass (z.B. mit Papierstaub) verunreinigte Luft von unten an die empfindlichen Druckköpfe der Druckeinrichtung 3 gelangt. Hierdurch können Wartungskosten eingespart werden.Since more blown air "from above" (ie from the further blower device 10) than "from below" (that is from the blower device 6) reaches the machine, it is advantageous prevents contaminated air (for example with paper dust) from reaching the sensitive print heads of the printing device 3 from below. This can save maintenance costs.
