Description

Die Erfindung betrifft eine Walze entsprechend dem Oberbegriff des Patentanspruchs 1. Solche Walzen werden vielfach dort eingesetzt, wo eine Beschichtung von Papier oder Karton in einem zwischen zwei Walzen gebildeten Preßspalt erfolgt. Dabei wird im allgemeinen eine geringe Auftragsmenge (spezifisches Flächengewicht) aufgetragen. Die Beschichtungsmassen weisen als Lösungsmittel üblicherweise erhebliche Mengen Wasser auf.The invention relates to a roller according to the preamble of claim 1. Such rollers are widely used where paper or cardboard is coated in a press nip formed between two rollers. A small application quantity (specific weight per unit area) is generally applied. The coating compositions usually have significant amounts of water as a solvent.

Bei Walzen, die mit einem Kunststoff, z.B. Polyurethan oder Polyamid, beschichtet sind, besteht die Gefahr, daß durch Hydrolyse Schädigungen auftreten, insbesondere der Haftschicht, die die Verbindung zwischen dem Kunststoffmantel und dem metallischen Walzenkern herstellt. Ferner kommt es zu einem Aufweichen des Kunststoffmantels, was zu einer Härteänderung desselben und einer Verminderung der Festigkeit desselben führt. Dadurch wird natürlich die Standzeit einer solchen Walze stark beeinträchtigt und sie muß frühzeitig ausgewechselt werden. Mit der erfindungsgemäßen Walze soll dieser Nachteil wesentlich eingeschränkt werden, was im wesentlichen dadurch geschieht, daß der Walzenkern eine höhere Temperatur erhält als der darauf aufgebrachte Mantel aus Kunststoff. Man kann zu dem Zweck die Walze direkt durch ein strömendes Wärmeträgermedium oder durch Heizstäbe oder -Wicklungen beheizen. Auch indirekte Maßnahmen oder Mittel zur Temperaturerhöhung des Walzenkerns, der vorzugsweise ja üblicherweise aus Metall ist, können zur Anwendung kommen.In the case of rolls which are coated with a plastic, for example polyurethane or polyamide, there is a risk that damage will occur as a result of hydrolysis, in particular the adhesive layer which establishes the connection between the plastic casing and the metallic roll core. Furthermore, there is a softening of the plastic jacket, which leads to a change in its hardness and a reduction in its strength. Of course, the service life of such a roller is greatly impaired and it must be replaced early. With the roller according to the invention, this disadvantage is to be substantially limited, which is essentially due to the fact that the roller core receives a higher temperature than the plastic jacket applied to it. For this purpose, the roller can be heated directly by a flowing heat transfer medium or by heating rods or windings. Indirect measures or means for increasing the temperature of the roller core, which is preferably usually made of metal, can also be used.

Durch die erfindungsgemäße Maßnahme wird nämlich verhindert, daß das Wasser von der Oberfläche des Walzenmantels und von der Beschichtungsmasse her in den Walzenmantel in Richtung auf den Walzenkern in zu starkem Maße eindringt. Dies geht natürlich sonst an sich nur sehr langsam vonstatten, jedoch noch zu schnell für eine akzeptable Standzeit der Walze bei deren betrieblichen Einsatz. Insbesondere ist es nur nötig, daß die Oberflächentemperatur des Walzenkerns geringfügig höher ist als die Oberflächentemperatur des Walzenmantels, jeweils radial außen. Im allgemeinen wird man keinen größeren Temperaturunterschied als 50 K anwenden.The measure according to the invention prevents namely that the water penetrates from the surface of the roller shell and from the coating composition into the roller shell in the direction of the roller core to an excessive extent. Of course, this is otherwise very slow, but still too fast for an acceptable service life of the roller during its operational use. In particular, it is only necessary that the surface temperature of the roller core is slightly higher than the surface temperature of the roller shell, in each case radially on the outside. In general, no temperature difference greater than 50 K will be used.

Beheizbare Walzen sind zwar in den verschiedensten Ausführungen bekannt, jedoch handelt es sich dabei um rein metallene Walzen, von denen eine hohe Oberflächentemperatur gefordert wird, z.B. für den vorherrschenden Einsatzzweck in Kalandern.Heated rollers are known in a wide variety of designs, but they are purely metal rollers, which require a high surface temperature, e.g. for the predominant application in calenders.

Die Walze nach der DE 37 41 232 A1 mit einem Gummimantel auf einem Metallkern wird allein zu dem Zweck von innen beheizt, eine sich heiß von einem Trägerband lösende Farbe auf einen Träger aufzubringen, insbesondere als Schriftzug oder Zahl. Hierbei treten weder Wasser noch sonstige Feuchtigkeit oder Lösungsmittel auf. Es handelt sich dabei auch nur um eine sehr kleine Walze von etwa 15 cm Länge, die billig ist und ohne große Kosten öfter erneuert werden kann.The roller according to DE 37 41 232 A1 with a rubber jacket on a metal core is heated from the inside solely for the purpose of applying a color which is hotly detached from a carrier tape to a carrier, in particular as a lettering or number. Neither water nor other moisture or solvents occur here. It is also just a very small roller about 15 cm in length, which is cheap and can be replaced more often without great expense.

Nachfolgend wird die Erfindung anhand den Figuren der Zeichnung dargestellt, wobei

Fig. 1
einen prinzipmäßigen Axialschnitt durch eine erfindungsgemäße Walze und
Fig. 2
einen Querschnitt durch eine erfindungsgemäße Walze in einer anderen Ausführungsform der Heizeinrichtung darstellt.
The invention is illustrated below with the aid of the figures in the drawing, in which:
Fig. 1
a basic axial section through a roller according to the invention and
Fig. 2
shows a cross section through a roller according to the invention in another embodiment of the heating device.

In Fig. 1 ist der Walzenkern mit 1 und der Walzenmantel mit 2 bezeichnet, wobei der Walzenkern ein Hohlzylinder aus Metall, vorzugsweise Stahl, ist. Dieser Hohlzylinder ist stirnseitig abgeschlossen und weist Wellenstümpfe 3 bzw. 4 auf, die ebenfalls eine zentrale Durchgangsbohrung 5 aufweisen. Dadurch ergeben sich natürliche Kanäle für die Zuleitung und Ableitung von Heizflüssigkeit oder Heizgas. Die Temperatur des Walzenkerns muß ja nur sehr wenige Grad oberhalb der Umgebungstemperatur bzw. der Temperatur der Streichmasse gehalten werden, falls diese erwärmt ist und somit auch den Walzenmantel erwärmt.In Fig. 1, the roll core with 1 and the roll shell with 2, the roll core is a hollow cylinder made of metal, preferably steel. This hollow cylinder is closed at the end and has stub shafts 3 and 4, which also have a central through bore 5. This results in natural channels for the supply and discharge of heating fluid or heating gas. The temperature of the roll core only has to be kept a very few degrees above the ambient temperature or the temperature of the coating slip if it is heated and thus also heats the roll shell.

In manchen Fällen findet jedoch keine Erwärmung der Streichmasse über die Umgebungstemperatur hinaus statt. So reicht dann eine Erwärmung der Walze auf etwa 30 bis 50°C. Es stellt sich dann ein natürlicher Temperatur-Gradient von dem Walzenkern zur Oberfläche des Walzenmantels ein.In some cases, however, the coating is not heated above the ambient temperature. So heating the roller to about 30 to 50 ° C is sufficient. A natural temperature gradient is then established from the roll core to the surface of the roll shell.

Es reicht theoretisch eine Temperatur-Differenz zwischen der Oberfläche des Mantels und der Oberfläche des Walzenkerns von 0,1 K, bevorzugt wird ein Bereich zwischen 1 und 20 K.Theoretically, a temperature difference between the surface of the jacket and the surface of the roll core of 0.1 K is sufficient, a range between 1 and 20 K is preferred.

Um eine besonders gleichmäßige Erwärmung der Walze zu erreichen, können besondere Einbauten vorgesehen werden, wie es z.B. aus DE-OS 32 39 471 und 38 02 477 sowie aus der US-PS 43 51 386 und der US-PS 42 52 184 bekannt ist.In order to achieve a particularly uniform heating of the roller, special internals can be provided, e.g. from DE-OS 32 39 471 and 38 02 477 and from US-PS 43 51 386 and US-PS 42 52 184 is known.

Eine andere Möglichkeit wäre natürlich, an der Innenoberfläche des hohlzylindrisch ausgebildeten Walzenkerns Heizstäbe oder Heizwicklungen vorzusehen. Die elektrische Heizleistung müßte dann über Schleifringe an einen Wellenstumpf übertragen werden.Another possibility would of course be to provide heating rods or heating coils on the inner surface of the hollow cylindrical roller core. The electrical heating power would then have to be transmitted to a stub shaft via slip rings.

Eine weitere Möglichkeit ist in Fig. 2 dargestellt, wo durch induktive Kopplung von einem Elektromagneten und dem Walzenkern Wirbelströme in demselben hervorgerufen werden, die zu einer Aufheizung des Kerns führen. Der Elektromagnet besteht dabei aus einem Eisenkern 8 mit zumindest einer Wicklung 9. In Fig.2 sind noch Heizstäbe 6 und Heizwicklungen 7 in Nuten 10 des Walzenkerns angedeutet.A further possibility is shown in FIG. 2, where eddy currents are generated in the same by inductive coupling of an electromagnet and the roll core, which eddy heating of the core. The electromagnet is there from an iron core 8 with at least one winding 9. In FIG. 2, heating rods 6 and heating windings 7 are also indicated in slots 10 of the roller core.

Eine mögliche Erklärung für den Effekt ist diese:
Es gelangen zwar immer noch einige Wassermoleküle bis zur Haftschicht des Walzenbezugs (Kunststoffmantel), jedoch nicht in so großer Menge, daß "Feuchtigkeitsnester" gebildet werden. Somit kann die "Feuchtigkeit" nicht ihr zerstörerisches Werk ausführen.A possible explanation for the effect is this:
A few water molecules still reach the adhesive layer of the roll cover (plastic jacket), but not in such a large amount that "moisture pockets" are formed. Thus, the "moisture" cannot do its destructive work.

Die Walze kann günstig in einer Streicheinrichtung mit zwei Preßwalzen nach US 48 48 268 oder mit zumindest einer die Warenbahn, z.B. insbesondere Papier- oder Kartonbahn, über einen gewissen Umschlingungswinkel führenden Gegenwalze einer Zufuhreinrichtung für Streichmasse, z.B. nach US 42 50 211, verwendet werden.The roller can inexpensively in a coating device with two press rollers according to US 48 48 268 or with at least one the web, e.g. especially paper or cardboard web, over a certain wrap angle counter roll of a feed device for coating, e.g. according to US 42 50 211 can be used.
