Abstract
Description
Die Erfindung bezieht sich auf eine von Temperiermitteln durchflossene Walze für Druckmaschinen, in deren Innern mantelartige Trennwände vorgesehen sind.The invention relates to a roller through which temperature control means flow for printing machines, in the interior of which jacket-like partition walls are provided.
Das Kühlen und Temperieren von Walzen, insbesondere von Farbwalzen in Farbwerken, ist beispielsweise durch die DE-AS 2658380 bekannt.The cooling and tempering of rollers, in particular of ink rollers in inking units, is known for example from DE-AS 2658380.
Um die Farbtemperatur bei Betriebsunterbrechung der Druckmaschine weitestgehend konstant und den Temperaturunterschied des Farbfilmes über die Walzenlänge gering zu halten, ist im Innern der Farbwalze ein Verdrängungskörper angeordnet und der noch freie Querschnitt der Farbwalze durch eine mantelartige Trennwand guter Wärmeleiteigenschaft in zwei konzentrische Ringspalte unterteilt, die vom Temperiermittel im Gegenstrom mit hoher Druckflussgeschwindigkeit durchflossen sind.In order to keep the ink temperature as constant as possible when the press is out of operation and to keep the temperature difference of the ink film low over the length of the roller, a displacement body is arranged inside the ink roller and the still free cross section of the ink roller is divided into two concentric ring gaps by a jacket-like partition wall with good thermal conductivity Tempering agents are flowed through in countercurrent at a high pressure flow rate.
Die Walzen eines Farbwerks an Druckmaschinen unterliegen während des Arbeitens einer Erwärmung, die mit der Druckgeschwindigkeit steigt.The rollers of an inking unit on printing presses are subject to heating during operation, which increases with the printing speed.
Nachteilig wirkt sich die Wärmeentwicklung, die durch Friktion der einzelnen Zylinder, Reiber und Gummiwalzen entsteht, auf die Druckerzeugnisse aus. Diese Erwärmung, die durch Lagerreibung, Abwälzen der Zahnräder und sonstige bewegte Teile im Bereich der Seitenwände entsteht, bewirkt das unerwünschte Tonen an den.kontrastrei- chen Stellen bedruckter Bogen. Die Erwärmung tritt besonders an den beiden Walzenenden verstärkt auf.The heat generated by the friction of the individual cylinders, rubbers and rubber rollers has a disadvantageous effect on the printed products. This heating, which is caused by bearing friction, rolling of the gears and other moving parts in the area of the side walls, causes undesired toning at the contrasting areas of printed sheets. The heating occurs particularly at the two roller ends.
Nachteilig ist ferner,-dass die Ableitung des Temperiermittels auf derselben Stirnseite der Walze angeordnet ist, wobei der Zustrom konzentrisch vom rücklaufenden Strom umgeben ist, da dadurch bereits vor der eigentlichen Kühlung eine Erwärmung des Temperiermittels erfolgt.Another disadvantage is that the discharge of the temperature control means is arranged on the same end face of the roller, the inflow being surrounded concentrically by the returning current, since this causes the temperature control means to be heated before the actual cooling.
Bekannt ist ferner aus der Patentschrift FR-A-1436320 eine Walze, die Blähkörper enthält, diese dient jedoch zur Papierhersterlung und ist als Farbwalze nicht geeignet, da die dort verwendeten Blähkörper zum Zwecke der radialen Verformbarkeit des Walzenmantels verwendet werden.Also known from patent specification FR-A-1436320 is a roller which contains swelling bodies, but this is used for paper manufacture and is not suitable as an inking roller, since the swelling bodies used there are used for the purpose of the radial deformability of the roll shell.
Durch zuvor benannte Nachteile stellt sich die Aufgabe, eine Walze so auszubilden, dass die Farbtemperatur bei Betriebsunterbrechungen der Druckmaschine nahezu konstant bleibt und sich kein Temperaturgefälle des Farbfilms über die Länge der Walze einstellt.Due to the disadvantages mentioned above, the task arises of designing a roller in such a way that the color temperature remains virtually constant when the printing machine is interrupted and there is no temperature gradient of the ink film over the length of the roller.
Die Aufgabe wird dadurch gelöst, wie dies im Kennzeichen des Anspruches 1 angegeben ist.The object is achieved as indicated in the characterizing part of claim 1.
Abrupte Temperaturunterschiede an der Kühlwalzenoberfläche können durch die zusätzliche Wärmedämmung nicht mehr auftreten.Abrupt temperature differences on the cooling roller surface can no longer occur due to the additional thermal insulation.
Vorteilhafterweise ist mittig in die Oberfläche des Aussenmantels der Farbwalze das wärmedämmende Element bündig eingearbeitet, wobei der Hohlraum der Walze eine oder mehrere Leitungen münden, die mit einem oder mehreren Behältern verbunden sind, in dem sich das unter Druck stehende Temperiermittel befindet.The heat-insulating element is advantageously incorporated flush into the middle of the surface of the outer surface of the inking roller, the cavity of the roller opening into one or more lines which are connected to one or more containers in which the pressurized temperature control medium is located.
Die Erfindung ist nachstehend an zwei bevorzugten Ausführungsbeispielen unter Bezugnahme auf die Zeichnung erläuert.The invention is explained below using two preferred exemplary embodiments with reference to the drawing.
In der abgebildeten Fig. 1 ist eine Farbwalze 9 mit innerem Gegenstrom-Wärmeaustausch abgebildet.1 shows an inking roller 9 with an internal countercurrent heat exchange.
Durch das Zulaufrohr 4 fliesst das Kühlmittel in den inneren Kühlkammerbereich 5 und tritt durch die Bohrung 6 in den mittleren Kühlkammerbereich 7 ein. Das Kühlmittel durchströmt den mittleren Kühlkammerbereich 7 in entgegengesetzter Richtung wie den inneren Kühlkammerbereich 5. Am Ende des mittleren Kühlkammerbereiches 7 tritt das Kühlmittel durch die Öffnung 10 in den äusseren Kühlkammerbereich 2, der von dem Aussenmantel der Farbwalze 1 begrenzt ist, und an der Innenseite des Aussenmantels ist in dessen Mitte das wärmedämmende Element 3 angebracht.The coolant flows through the inlet pipe 4 into the inner
Das Kühlmittel fliesst nun wieder in gleicher Richtung wie im inneren Kühlkammerbereich 5 oder, anders ausgedrückt, in entgegengesetzter Richtung wie im mittleren Kühlkammerbereich 7. Durch das wärmedämmende Element 3 wird im äusseren Kühlkammerbereich 2 eine Querschnittverengung 11 hergestellt, die eine Geschwindigkeitszunahme auf einen Druckabfall in der Strömungsrichtung bei dem Kühlmittel hervorruft. Nachdem das Kühlmittel die Querschnittverengung 11 des äusseren Kühlkammerbereiches 2 passiert hat, nimmt die Geschwindigkeit des Kühlmittels ab, und es erfolgt gleichzeitig ein Druckanstieg in Strömungsrichtung. Am Ende des äusseren Kühlkammerbereichs 2 tritt das Kühlmittel durch die Ablaufbohrung 12 aus und fliesst durch das Ablaufrohr 8 ab.The coolant now flows again in the same direction as in the inner
Auch in Fig. 2 ist eine Farbwalze 9 mit innerem Gegenstrom-Wärmeaustausch abgebildet. Das Zu- und Abflusssystem ist ebenso wie in Fig. 1 geartet. Das wärmedämmende Element 14 ist mittig in den Aussenmantel 15 der Farbwalzen 13 eingearbeitet und wirkt isolierend.In Fig. 2, an ink roller 9 is shown with internal countercurrent heat exchange. The inflow and outflow system is the same as in FIG. 1. The heat-insulating
Die dargestellten Ausführungsbeispiele stellen keineswegs die einzige Ausführungsmöglichkeit dar. Es ist z. B. denkbar, das wärmedämmende Element auf der Aussenwandung aufliegen zu lassen, um den gleichen Effekt zu erzielen.The illustrated embodiments are by no means the only possible embodiment. B. conceivable to let the heat-insulating element rest on the outer wall to achieve the same effect.
