Description

Die Erfindung betrifft eine Einrichtung zur Bedruckstoff- und Druckwerkskühlung mittels gekühlter Blasluft an Bogenrotationsdruckmaschinen gemäß Oberbegriff des ersten Anspruches.
Es ist allgemein bekannt, zur Unterstützung des Trocknungs- und Aushärtungsprozesses von Druckfarben und insbesondere Lacken Trockner an oder zwischen den Druckwerken sowie im Auslagebereich anzuordnen. Dabei werden primär (Infrarot-Trockner) oder sekundär (UV-Trockner) große Wärmemengen an den Bedruckstoff und die an die Trockner angrenzenden Druckmaschinenbaugruppen abgegeben. Die durch Konvektion oder Strahlung abgegebene und nicht für den Trocknungsprozess genutzte Wärmemenge gilt als Störgröße für den Druckprozess und die Bogenablage (Beeinträchtigung des Druckes im nachfolgenden Druckwerk, überhöhte Stapeltemperatur, Beschädigung thermisch sensibler Bedruckstoffe) und beeinträchtigt darüber hinaus die Funktionsweise benachbarter Maschinenelemente, wenn sich diese unzulässig erhitzen. Darüber hinaus müssen sämtliche Materialien im Trocknerwirkungsbereich extrem hitzebeständig ausgeführt sein (Kabel, Schläuche, Sensoren, Pneumatikzylinder usw.).The invention relates to a device for printing substrate and printing unit cooling means of cooled blown air on sheet-fed rotary printing machines according to the preamble of the first claim.
It is generally known to arrange driers at or between the printing units and in the display area in order to support the drying and curing process of printing inks and in particular paints. In this case, primary (infrared dryer) or secondary (UV dryer) large amounts of heat are delivered to the substrate and adjacent to the dryer printing press assemblies. The amount of heat given off by convection or radiation and not used for the drying process is regarded as a disturbance variable for the printing process and the sheet deposition (impairment of the printing in the subsequent printing unit, excessive stacking temperature, damage to thermally sensitive substrates) and also impairs the functioning of adjacent machine elements, if these heat inadmissible. In addition, all materials in the dryer area must be extremely heat-resistant (cables, hoses, sensors, pneumatic cylinders, etc.).

Zur Vermeidung der Überhitzung von Druckmaschinenelementen im Trocknerbereich und zur Bedruckstoffabkühlung sind zusätzliche Kühleinrichtungen bekannt.To avoid the overheating of printing machine elements in the dryer area and for printing material cooling additional cooling devices are known.

Aus der DE 9214459 U1 ist z.B. eine Absaugungseinrichtung zur Ableitung erwärmter Luft aus dem Trocknerbereich in der Bogenauslage bekannt, die jedoch nicht die durch Strahlung erhitzten Bogenleitflächen kühlt.
Zur Bogenführung im Wirkungsbereich von Trocknern werden Leitbleche beschrieben, auf deren Unterseite Kühlmittelkanäle angeordnet sind (z.B. DE 19810387 C1 ). Allerdings beschränkt sich deren Kühlwirkung nur auf das Leitblech, eine Kühlung auch der angrenzenden Maschinenteile oder des Bedruckstoffes kann damit nicht erreicht werden.
Der Einsatz gekühlter Blasluft zur Druckplattenkühlung ist beispielsweise aus der EP 0480230 A1 bekannt sowie die Zylinderkühlung mittels Blasluft aus der DE 4326835 A1 .
Die Blasluftkühlung nach der EP 0480230 A1 weist eine Kombination von Ventilatoren und geregeltem Kühler auf, die nur für die Druckplattenkühlung vorgesehen ist und als Spaltdüse mit dementsprechend geringem Wirkungsbereich ausgebildet ist. Die DE 4202544 A1 und DE 4326835 A1 zeigen zusätzliche Blasluftkühlbalken mit teilweisem Kühlluftkreislauf für Gummi- oder Plattenzylinder, die für eine Bogenführung nicht geeignet sind.From the DE 9214459 U1 For example, a suction device for discharging heated air from the dryer area in the sheet delivery is known, but does not cool the heated by radiation sheet guide surfaces.
For sheet guiding in the field of action of dryers baffles are described on the underside coolant channels are arranged (eg DE 19810387 C1 ). However, their cooling effect is limited only to the baffle, a cooling of the adjacent machine parts or the printing material can not be achieved.
The use of cooled blast air for pressure plate cooling is for example from the EP 0480230 A1 known as well as the cylinder cooling by means of blowing air from the DE 4326835 A1 ,
The blown air cooling after the EP 0480230 A1 has a combination of fans and controlled cooler, which is provided only for the pressure plate cooling and is designed as a gap nozzle with a correspondingly low effective range. The DE 4202544 A1 and DE 4326835 A1 show additional Blasluftkühlbalken with partial cooling air circuit for rubber or plate cylinder, which are not suitable for sheet guiding.

Aus der WO 01/32423 A1 ist es weiterhin bekannt, von Trocknern erwärmte Druck- und Übergabezylinder sowie dadurch indirekt auch die Bedruckstoffe mit Hilfe von gekühlter Blasluft aus zusätzlich vor der Druckzone angeordneten Kühleinheiten zu kühlen, die Kühlregister und Ventilatoren aufweisen.From the WO 01/32423 A1 It is also known, heated by dryers pressure and transfer cylinder and thereby indirectly also to cool the substrates with the help of cooled blowing air from additionally arranged in front of the pressure zone cooling units having cooling registers and fans.

Den genannten Blasluftkühlsystemen sind die Nachteile gemeinsam, dass sie zusätzlichen Bauraum benötigen, die den Zugang zu den Maschinenbaugruppen bei Reinigungs- oder Einrichtungshandlungen zusätzlich erschweren, und sie sind jeweils nur für spezielle Kühlaufgaben ausgelegt. Im Allgemeinen reicht der noch entlang des Bogenweges verbliebene Platz zwischen Trocknern, Bogenleiteinrichtungen, Wascheinrichtungen oder Autoregistereinrichtungen auch nicht aus für eine wirksame Kühlung sowohl der erhitzten Maschinenelemente als auch der den Trocknern ausgesetzten Bedruckstoffe.The said blown air cooling systems have the common disadvantages that they require additional space, which further complicate access to the machine assemblies in cleaning or furnishing actions, and they are each designed only for specific cooling tasks. In general, the remaining space along the sheet path between dryers, sheet guiding devices, washing devices or automatic register devices is also insufficient for effective cooling of both the heated machine elements and the substrates exposed to the dryers.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Einrichtung zu schaffen, die bei geringstem Platzbedarf sowohl die Bedruckstoffe als auch die von den Trocknern unerwünscht miterhitzten Maschinenelemente effektiv zu kühlen vermag.The invention is therefore based on the object to provide a device that is able to effectively cool both the substrates and the undesirable miterhitzten of the dryers machine elements with minimal space requirements.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.
Einzelheiten von Ausführungsformen der Erfindung sind Gegenstand von Unteransprüchen.According to the invention, this object is solved by the features of claim 1.
Details of embodiments of the invention are the subject of dependent claims.

Die erfindungsgemäße Lösung nutzt die entlang des gesamten Bogenweges vorhandenen pneumatischen Bogenleitelemente vor und nach der Druckzone, unterhalb von Übergabeund Wendetrommeln und im Auslagebereich durch Integration von Kühleinrichtungen für die Kühllufterzeugung und -zufuhr zum Bedruckstoff und die davon abströmende Blasluft für die konvektive Kühlung der erhitzten Maschinenbereiche, so dass Bedruckstoff und Druckmaschine entlang des gesamten Bogenweges wirksam gekühlt werden. Gegenüber der Zuordnung einer zentralen Kühleinrichtung zu mehreren Blaseinrichtungen, wie in der DE 09310028 U1 für Blaskästen in der Bogenauslage offenbart, ergeben sich große Vorteile bzgl. Platzbedarf, Regelbarkeit der Kühlleistung an jeder einzelnen Blaseinrichtung und auch bzgl. der Kühlwirkung, da einerseits eine unerwünschte Wärmeaufnahme über die verbindenden Luftleitungen bei der erfindungsgemäßen Integration der Kühleinrichtungen in die Blaseinrichtung verhindert wird und andererseits der durchsetzbare Blasluftstrom nicht durch die Schlauchquerschnitte begrenzt wird.The solution according to the invention uses the pneumatic sheet guiding elements present along the entire sheet path before and after the printing zone, below transfer and turning drums and in the delivery area by integration of cooling devices for the cooling air generation and supply to the printing material and the blown air for the convective cooling of the heated machine areas, so that printing material and printing press are effectively cooled along the entire sheet path. Compared to the assignment of a central cooling device to a plurality of blowing devices, as in the DE 09310028 U1 disclosed for blow boxes in the sheet delivery, there are great advantages in terms of space requirements, controllability of the cooling performance of each blower and also with respect to the cooling effect, since on the one hand unwanted heat absorption through the connecting air ducts in the integration of the cooling devices according to the invention is prevented in the blowing device and on the other hand, the enforceable blast air flow is not limited by the tube cross-sections.

Durch die Kühlluftzufuhr über die vorhandenen pneumatischen Bogenleiteinrichtungen entlang des zu kühlenden Bogenweges werden gegenüber der bisher üblichen ausschließlichen Kühlluftzuführung über zusätzliche Blaseinrichtungen oberhalb der Übergabebereiche zwischen den bogenführenden Zylindern deutliche Vorteile erzielt:

  • geringer zusätzlicher konstruktiver Aufwand durch die Nutzung vorhandener Bogenleiteinrichtungen
  • bessere Kühlwirkung durch Integration von Kühleinrichtungen in die Blasluftkästen unter den Übergabetrommeln, da die unterhalb der Übergabezylinder angesaugte Luft wesentlich kühler als die von bisher üblichen Kühleinrichtungen oberhalb der Druckzylinder angesaugte Luft ist
  • Die Kühlluft wird über den zu kühlenden Druckmaschinenbereich aufgrund der Blasluftkühlung über mehrere Bogenleiteinrichtungen gleichmäßiger verteilt
  • Einwirkzeit und abgeleiteter Wärmestrom werden um ca. das Vierfache gesteigert.
By the cooling air supply via the existing pneumatic sheet guiding along the sheet path to be cooled significant advantages are achieved over the previously customary exclusive cooling air supply via additional blowing devices above the transfer areas between the sheet-guiding cylinders:
  • low additional design effort through the use of existing sheet guiding devices
  • better cooling effect by integration of cooling devices in the blast boxes under the transfer drums, since the air sucked in below the transfer cylinder is much cooler than the air sucked in by conventional cooling devices above the impression cylinder
  • The cooling air is distributed more uniformly over the press area to be cooled due to the Blasluftkühlung over several sheet guiding devices
  • Exposure time and derived heat flow are increased by about fourfold.

Anhand der Zeichnungen sollen nachstehend Ausführungsformen der Erfindung erläutert werden.

Fig.1 zeigt in schematischer Darstellung die bogenführenden Zylinder von zwei Druck- bzw. Lackwerken einer Bogenrotationsdruckmaschine in Reihenbauweise, zwischen denen sich eine Übergabetrommel 3 befindet. Vom in Bogenlaufrichtung vorgeordneten Druckwerk und vom nachgeordneten Druckwerk sind jeweils nur die Druckzylinder 2;4 und die damit zusammenwirkenden Gummizylinder 1;5 dargestellt. Entlang des Bogenweges sind je nach Druckauftrag und Maschinenkonfiguration pneumatische Bogenleiteinrichtungen angeordnet, von denen beispielhaft die Bogenleiteinrichtungen 7,9,10,11 dargestellt sind. Fig.1 shows a schematic representation of the sheet-guiding cylinder of two printing or coating units of a sheet-fed rotary printing machine in a row construction, between which a transfer drum 3 is located. From upstream in the sheet running direction printing unit and the downstream printing unit only the impression cylinder 2, 4 and the cooperating blanket cylinders 1, 5 are shown. Depending on the print job and machine configuration, pneumatic sheet guiding devices are arranged along the sheet path, of which the sheet guiding devices 7, 9, 10, 11 are shown by way of example.

Unterhalb der Übergabetrommel 3 befindet sich ein bekannter Blaskasten 7, der das Abschmieren der bedruckten Bogen am Luftpolsterblech 8 verhindert. Vor der Druckzone 4,5 des Folgedruckwerkes wird der Bogen mit Hilfe eines Blaskastens 9 und je nach Bedruckstoffdicke von zusätzlichen Blasrohren 10.1,10.2 an den Druckzylinder 4 glatt angelegt.
Wenn im vorgeordneten Druckwerk eine UV-Farbe oder ein Lack aufgetragen wird, dann wird der Bogen mit Hilfe eines Zwischentrockners 12, der zwischen Druckzone 1,2 und Bogen-Übergabebereich 2,3 angeordnet ist, getrocknet. Dabei handelt es sich entweder um einen Infrarottrockner oder um einen UV-Trockner. Aus dem Stand der Technik ist es bekannt, zur Abkühlung des Bogens nach dem Passieren des Trockners 12 eine Blasluftkühlung 11 vorzusehen.
Diese reicht jedoch insbesondere bei UV-Trocknern nicht für eine wirksame Bogenkühlung aus und vermag nicht das Aufheizen der den Trockner umgebenden Druckmaschinenbereiche, besonders des Druckzylinders 2 und der Übergabetrommel 3, zu verhindern. Der Wärmestrahlung des Trockners 12 sind aber auch - in Abhängigkeit von der Größe und Anordnung der Blasluftkühlung - der vorgeordnete Gummizylinder 1 und der nachgeordnete Druckzylinder 4 ausgesetzt.
Zur Kühlung der erwärmten Bedruckstoffe und Druckmaschinenelemente sind nun erfindungsgemäß pneumatische Bogenleiteinrichtungen im Wirkungsbereich der Trockner 12 und entlang des weiteren Bogenweges bis hin zur Bogenablage mit einer Kühleinrichtung ausgestattet, die je nach verfügbarem Bauraum und in Abhängigkeit von der Art der Bogenleiteinrichtung ausgebildet sein kann. Die Kühleinrichtung ist dabei innerhalb von Blasluftkästen im Saug- und/oder Blasluftstrom von Ventilatoren angeordnet oder dem Blasluftstrom von Blasrohren zugeordnet und als Kühlregister mit flüssigkeitsdurchströmten Kühlflächen ausgebildet. Das Kühlmedium kann dabei Wasser, Kühlsole oder ein Gas sein, wobei der Kühlmittelstrom regelbar ist. Die Kühlflächen können bei entsprechender Gestaltung gleichzeitig als Leitflächen für die gewünschte Blasluftführung an der Bogenleiteinrichtung dienen.
In einem Blasluftkasten 7 unterhalb der Übergabetrommel 3 ist eine Kühleinrichtung 6.1 im Blasluftstrom eines das Luftpolsterblech 8 mit Blasluft versorgenden Ventilators 6.2 angeordnet, wobei die Kühlflächen in vorteilhafter Weise als lamellenförmige Luftleitelemente gem. Fig.1 ausgebildet sein können, die den vom Ventilator 6.2 kommenden Blasluftstrom gleichmäßig über das Bogenleitblech verteilen und den Luftstrom dabei abkühlen. Wird das Luftpolsterblech 8 von mehreren Ventilatoren 6.2 beaufschlagt oder ist der Blasluftkasten 7 in mehrere Kammern mit jeweils separaten Ventilatoren unterteilt, kann jedem Ventilator 6.2 eine Kühleinrichtung 6.1 modular zugeordnet sein, wobei diese auch untereinander mit ihren Kühlmittelvor- und -rückläufen zu einem Kreislauf verbunden sein können.Below the transfer drum 3 is a known blow box 7, which prevents the greasing of the printed sheet on the air cushion sheet 8. Before the printing zone 4, 5 of the subsequent printing unit, the sheet is smoothly applied by means of a blow box 9 and depending on the substrate thickness of additional blowpipes 10.1, 10.2 to the printing cylinder 4.
If a UV ink or a varnish is applied in the upstream printing unit, then the sheet is dried by means of an intermediate dryer 12, which is arranged between the printing zone 1, 2 and the sheet transfer area 2, 3. It is either an infrared dryer or a UV dryer. From the prior art, it is known to provide a Blasluftkühlung 11 for cooling the sheet after passing through the dryer 12.
However, this is not sufficient in particular for UV dryers for effective arc cooling and can not prevent the heating of the dryer surrounding printing press areas, especially the impression cylinder 2 and the transfer drum 3. But the heat radiation of the dryer 12 are also - depending on the size and arrangement of Blasluftkühlung - the upstream rubber cylinder 1 and the downstream pressure cylinder 4 exposed.
For cooling the heated substrates and printing machine elements now pneumatic sheet guiding devices are in the range of the dryer 12 and along the other Bogenweges up to the sheet storage equipped with a cooling device, which can be designed depending on the available space and depending on the type of sheet guiding device. The cooling device is arranged inside of blast air boxes in the suction and / or blast air flow of fans or associated with the Blasluftstrom of blowguns and formed as a cooling register with liquid-flow cooling surfaces. The cooling medium may be water, cooling brine or a gas, wherein the coolant flow is controllable. The cooling surfaces can serve with appropriate design at the same time as a guide surfaces for the desired Blasluftführung on the sheet guiding device.
In a Blasluftkasten 7 below the transfer drum 3, a cooling device 6.1 is arranged in the Blasluftstrom a the air cushion sheet 8 supplying blower air fan 6.2, wherein the cooling surfaces in accordance with the invention advantageously as a lamellar air guide elements. Fig.1 may be formed, which distribute the coming of the fan 6.2 Blasluftstrom evenly over the sheet guide and thereby cool the air flow. If the air cushion sheet 8 acted upon by several fans 6.2 or the Blasluftkasten 7 is divided into several chambers, each with separate fans, each fan 6.2 a cooling device 6.1 be assigned modular, which also be interconnected with their Kühlmittelvor- and recirculation to a circuit can.

Im Falle mehrerer nebeneinander angeordneter Ventilatoren 6.2 kann es zweckmäßig sein, die Kühlflächen parallel zur Bogentransportrichtung nebeneinander anzuordnen, wobei die äußere Kontur der Kühlflächen der Form des Blaskastens 7 angenähert ist. Da sich die Kühlflächen hierbei über fast das gesamte Innenvolumen des Blaskastens 7 erstrecken können, wird damit eine hohe Kühlleistung übertragbar.In the case of several juxtaposed fans 6.2, it may be appropriate to arrange the cooling surfaces parallel to the sheet transport direction next to each other, wherein the outer contour of the cooling surfaces of the shape of the blow box 7 is approximated. Since the cooling surfaces in this case can extend over almost the entire inner volume of the blow box 7, thus a high cooling capacity is transferable.

Blasrohren 10.1, 10.2 zugeordnete Kühleinrichtungen 20 (Fig. 2) weisen sich in Blasstrahlrichtung erstreckende Kühlflächenreihen mit Kühlmittelkanälen 21 auf, wobei die Kühlflächen aufgrund des für Blasrohre in der Regel zur Verfügung stehenden geringen Bauraumes kompakt gestaltet und in ihrer Kontur entsprechend dem Bogenweg geformt sind. Die Kühlflächen dienen in einer vorteilhaften Weiterbildung gleichzeitig als Halterung für die Blasrohre 10.1, 10.2..
Eine Anordnung von Leitstäben 19 im Wirkungsbereich von Kühlflächen, wie beispielhaft für die Bogenleiteinrichtung 13 nach der Druckzone 1,2 dargestellt, besitzt den Vorteil, dass diese nicht durch eine separate Kühlung (wie z.B. gemäß DE 19829383 ) gekühlt werden müssen. Anstelle von Leitstäben können auch bis zur Bogenbahn verlängerte Kühlflächen der Kühleinrichtung 13.1 vorgesehen sein.
In Fig. 3 ist eine erfindungsgemäße Bogenleiteinrichtung 15,16 in der Auslage unmittelbar in der Trocknerzone 14 dargestellt, die auch in mehreren Modulen vorhanden sein kann. Analog zum Blaskasten 7 in Fig. 1 befindet sich erfindungsgemäß ein Kühlregister 15.1 im Blasluftstrom eines den Blaskasten 16 mit Blasluft beaufschlagenden Ventilators 15.2, wobei auch mehrere Ventilatoren 15.2 und Kühlregister 15.1 in einer Reihe rechtwinklig zur Transportrichtung am Blaskasten 16 angeordnet sein können.
Die Trockner 14 oberhalb des Bogenweges können zur Ableitung der von den Trocknern 14 aufsteigenden Warmluft und zur Abschirmung umliegender Druckmaschinenelemente vor der Wärmestreustrahlung der Trockner 14 mit einer Absaugvorrichtung 22 ausgestattet sein.Blowing tubes 10.1, 10.2 associated cooling devices 20 ( Fig. 2 ) have in the Blasstrahlrichtung extending rows of cooling surfaces with coolant channels 21, wherein the cooling surfaces are made compact due to the space available for blowpipes usually small space and formed in their contour according to the Bogenweg. The cooling surfaces are used in an advantageous development at the same time as a holder for the blowpipes 10.1, 10.2 ..
An arrangement of guide bars 19 in the area of action of cooling surfaces, as shown by way of example for the sheet guiding device 13 according to the printing zone 1, 2, has the advantage that it is not separated by a separate cooling (such as, for example) DE 19829383 ) must be cooled. Instead of guide bars, extended cooling surfaces of the cooling device 13.1 can also be provided up to the curved path.
In Fig. 3 a sheet guiding device 15,16 according to the invention is shown in the delivery directly in the dryer zone 14, which may also be present in several modules. Analogous to the blow box 7 in Fig. 1 According to the invention, there is a cooling register 15.1 in the blast air flow of a fan 15.2 acting on the blow box 16, wherein several fans 15.2 and cooling register 15.1 can also be arranged in a row at right angles to the transport direction on the blow box 16.
The driers 14 above the sheet path can be equipped with a suction device 22 for discharging the hot air rising from the dryers 14 and for shielding surrounding printing machine elements from the heat radiation from the driers 14.

Die in den Kühleinrichtungen 6.1,9.1,11.1,13.1,15.1 gekühlte Blasluft durchströmt die Bogenleiteinrichtungen und kühlt zunächst die dem Bogen zugewandten Leitflächen. Das außerhalb der Bogenleiteinrichtungen 6,9,11,13,15 erzeugte Luftpolster kühlt den Bogen und die Trommel- bzw. Zylinderoberfläche und schützt den Bogen so vor thermischen Verformungen oder Schäden. Beim Abströmen der Kühlluft aus der Bogenführungszone werden zusätzlich die umliegenden Maschinenelemente konvektiv mitgekühlt. Besonders effektiv wirkt der Luftkasten 7. Aufgrund seiner Ausdehnung kühlt er die Bogen sehr wirksam und verteilt die Kühlluft gleichmäßig, bevor sie in die benachbarten Druckwerke zwecks Temperierung strömt. Einwirkzeit und Kühlleistung können so gegenüber herkömmlichen Blasluftkühleinrichtungen um den Faktor 4 gesteigert werden.
Die Anordnung der erfindungsgemäßen Bogenleiteinrichtungen 13,20 kann weiterhin gemäß Fig.2 in vorteilhafter Weise so gewählt werden, dass sie die Zylinderoberflächen vor Wärmestreustrahlungen der Trockner abschirmen und somit noch einen zusätzlichen, sekundären Kühleffekt bewirken.The cooling air cooled in the cooling devices 6, 6, 9, 11, 11, 13, 1, 15. 1 flows through the sheet guiding devices and initially cools the guide surfaces facing the arc. The air cushion generated outside the sheet guiding devices 6,9,11,13,15 cools the sheet and the drum or cylinder surface and protects the sheet so from thermal deformation or damage. When the cooling air flows out of the sheet guiding zone, the surrounding machine elements are convectively co-cooled as well. Due to its expansion, it cools the bow very effectively and evenly distributes the cooling air before it enters the adjacent printing units for the purpose of temperature control flows. Exposure time and cooling capacity can be increased by a factor of 4 compared to conventional air-cooled units.
The arrangement of the sheet guiding devices 13, 20 according to the invention can continue according to FIG Fig.2 be chosen in an advantageous manner so that they shield the cylinder surfaces from heat radiation of the dryer and thus still cause an additional, secondary cooling effect.
