Abstract

Printing-press roller traversed by a temperature-regulating medium and having jacket-like partitions in the interior thereof surrounded by an outer circumferential wall, includes at least one heat-insulating element disposed in a middle region of the circumferential roller wall, the element forming an impediment to a transfer of heat on the surface of the circumferential roller wall in longitudinal direction thereof.

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 presses, 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 26 58 380 bekannt.. The cooling and tempering of rollers, in particular ink rollers in inking units, is known for example from DE-AS 26 58 380.

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 Durchflußgeschwindigkeit 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 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 kontrastreichen 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 warming, 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 high-contrast 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 tempering agent is arranged on the same end face of the roller, the inflow being surrounded concentrically by the returning stream, since this causes the temperature control agent to be heated before the actual cooling.

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 during interruptions in operation of the printing press remains almost constant and there is no temperature gradient of the ink film over the length of the roller.

Die Aufgabe wird dadurch gelöst, daß im mittleren Bereich der Walzenwandung ein oder mehrere wärmedämmende Elemente angeordnet sind, die den Wärmetransport auf der Oberfläche der Kühlwale in deren Längsrichtung behindern.The object is achieved in that one or more heat-insulating elements are arranged in the central region of the roller wall, which hinder the heat transfer on the surface of the cooling whales in their longitudinal direction.

Erfindungsgemäß ist mittig im äußeren Kühlkammerbereich das wärmedämmende Element angeordnet, oder es ist mittig in die Oberfläche des Außenmantels der Farbwalze das wärmedämmende Element bündig eingearbeitet.According to the invention, the heat-insulating element is arranged centrally in the outer cooling chamber region, or the heat-insulating element is incorporated flush into the surface of the outer jacket of the inking roller.

In vorteilhafter Weise ist der Hohlraum der Walze beidseitig mit Flanschen verschlossen, in den durch entsprechende Rohrstücke die Temperiermittel zu-und abgeleitet werden, um der Mehrerwärmung an den beiden Walzenenden entgegenzuwirken.Advantageously, the cavity of the roller is closed on both sides with flanges, in which the temperature control means are fed in and out through appropriate pipe pieces, in order to counteract the additional heating at the two roller ends.

Durch die Zuleitung des Temperiermittels auf der Antriebsseite wird zunächst das mehr erwärmte Walzenende umspült.The more heated roller end is first washed around by the supply of the temperature control on the drive side.

Bei einer vorteilhaften Ausführungsform der Erfindung wird das Temperiermittel durch den inneren Kühlkammerbereich, dann durch den mittleren Kühlkammerbereich und im Anschluß daran durch den äußeren Kühlkammerbereich unter dem mittig angeordneten wärmedämmenden Element, bestehend aus einem Rohrstück, hindurch zu dem für den Abfluß vorgesehenen Rohrstück geleitet.In an advantageous embodiment of the invention, the temperature control medium is passed through the inner cooling chamber region, then through the central cooling chamber region and then through the outer cooling chamber region under the centrally arranged heat-insulating element, consisting of a pipe section, to the pipe section provided for the drain.

Abrupte Temperaturunterschiede an der Kühlwalzenoberfläche können durch diese zusätzliche Wärmedämmung nicht mehr auftreten.Abrupt temperature differences on the cooling roller surface can no longer occur due to this additional thermal insulation.

Die Erfindung ist nachstehend an zwei bevorzugten Ausführungsbeispielen unter Bezugnahme auf die Zeichnung erläutert.The invention is explained below using two preferred exemplary embodiments with reference to the drawing.

In der abgebildeten Figur 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 cooling chamber area 5 and enters the central cooling chamber area 7 through the bore 6. The coolant flows through the central cooling chamber region 7 in the opposite direction set direction as the inner cooling chamber area 5. At the end of the middle cooling chamber area 7., the coolant passes through the opening 10 into the outer cooling chamber area 2, which is delimited by the outer jacket of the inking roller 1, and on the inside of the outer jacket is the heat-insulating in the middle thereof Element 3 attached.

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 Querschnittsverengung 11 hergestellt, die eine Geschwindigkeitszunahme und einen Druckabfall in der Strömungsrichtung bei dem Kühlmittel hervorruft. Nachdem das Kühlmittel die Querschnittsverengung 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 cooling chamber area 5 or, in other words, in the opposite direction as in the central cooling chamber area 7. The insulating element 3 produces a cross-sectional constriction 11 in the outer cooling chamber area 2, which increases the speed and the pressure drops in the Flow direction in the coolant causes. After the coolant has passed the cross-sectional constriction 11 of the outer cooling chamber region 2, the speed of the coolant decreases and there is at the same time an increase in pressure in the flow direction. At the end of the outer cooling chamber area 2, the coolant exits through the drain hole 12 and flows out through the drain pipe 8.

Auch in Figur 2 ist eine Farbwalze 9 mit innerem Gegenstrom-Wärmeaustausch abgebildet. Das Zu- und Abflußsystem ist ebenso wie in Figur 1 geartet. Das wärmedämmende Element 14 ist mittig in den Außenmantel 15 der Farbwalzen 13 eingearbeitet und wirkt isolierend.In Figure 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 element 14 is incorporated in the center of the outer jacket 15 of the inking rollers 13 and has an insulating effect.

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 exemplary embodiments shown are by no means the only possible embodiment. conceivable to let the heat-insulating element rest on the outer wall in order to achieve the same effect.
