Abstract

The calender assembly has two separate stacks of rollers, where one has the upper roller with bending compensation, and the other has a lower bending compensation roller. Both roller stacks (2,3) are over each other.

Description

Die Erfindung betrifft einen Kalander mit zwei voneinander getrennt arbeitenden Walzenstapeln, von denen jeder eine als Durchbiegeausgleichswalze ausgebildete Oberwalze und eine als Durchbiegeausgleichswalze ausgebildete Unterwalze aufweist.The invention relates to a calender with two from each other separately working roll stacks, each of which one designed as a deflection compensation roller Top roller and a deflection compensating roller designed Has lower roller.

Ein derartiger Kalander ist beispielsweise aus der älteren deutschen Patentanmeldung 195 08 353 bekannt.Such a calender is, for example, from the older one German patent application 195 08 353 known.

Derartige Kalander haben den Vorteil, daß man die beiden Seiten einer Materialbahn, beispielsweise einer Papierbahn, mit praktisch gleichen Ergebnissen behandeln kann. Die Gesamtzahl der Walzen kann geringer gehalten werden als in einem herkömmlichen Viel-Walzen-Kalander, der typischerweise mit zwölf Walzen ausgerüstet war. Die Steuerung der Druckspannungen in den einzelnen Walzenspalten kann mit höheren Freiheitsgraden erfolgen. Such calenders have the advantage that the two Sides of a material web, for example one Paper web, treat with practically the same results can. The total number of rollers can be kept lower than in a conventional multi-roll calender, typically equipped with twelve rollers was. The control of the compressive stresses in the individual Nips can be used with higher degrees of freedom respectively.

Allerdings hat die Ausbildung der Kalander mit zwei voneinander getrennt arbeitenden Walzenstapeln einen erhöhten Raumbedarf. Darüber hinaus sind zwei neue Kalanderständer notwendig, die, wie dies aus der deutschen Patentanmeldung 195 08 353 ersichtlich ist, so angeordnet sind, daß die Walzenebenen, d.h. die Ebenen, in denen die Achsen der einen Walzenstapel bildendenen Walzen angeordnet sind, parallel und hintereinander angeordnet sind. Beides hat erhöhte Investitionskosten zur Folge. Eine Nachrüstung ist aufgrund eines beschränkten Platzangebotes in manchen Fällen gar nicht möglich.However, the calender training with two roller stacks operating separately from one another increased space requirements. In addition, there are two new calender stands necessary which, like this from the German patent application 195 08 353 can be seen, are arranged so that the roll planes, i.e. the levels in which the axes of those forming a roll stack Rollers are arranged in parallel and one behind the other are arranged. Both have increased investment costs result. Retrofitting is due to a limited space in some cases not at all possible.

Der Erfindung liegt die Aufgabe zugrunde, einen obengenannten Kalander möglichst kostengünstig bauen oder einfach nachrüsten zu können.The invention has for its object an above Build calenders as cheaply as possible or easy to retrofit.

Diese Aufgabe wird bei einem Kalander der eingangs genannten Art dadurch gelöst, daß beide Walzenstapel übereinander angeordnet sind.This task is performed on a calender of the type mentioned at the beginning Art solved in that both roll stacks are arranged one above the other.

Mit dieser Ausgestaltung benötigt man in Bahnlaufrichtung nur noch den Platz eines einzelnen Kalanders. Dieser ist zwar etwa doppelt so hoch, wie ein einzelner Walzenstapel. Der Platz in der Höhe steht jedoch in den meisten Fabrikationshallen ohnehin zur Verfügung, weil auch die Papiermaschine eine relativ große Bauhöhe aufweist. Die Position der Aufwicklung, die einem derartigen Kalander in der Regel nachgeschaltet ist, bleibt bestehen, so daß das Gebäude insgesamt kürzer geplant oder gehalten werden kann. Die Papierführung wird einfacher. Der Weg zwischen den beiden Walzenstapeln wird kürzer, so daß die Materialbahn zwischen den Behandlungen in den beiden Walzenstapeln nur in geringerem Maße den Umgebungsbedingungen ausgesetzt ist. Eine Papierbahn hat beispielsweise weniger Zeit, auszutrocknen oder abzukühlen. Es lassen sich also mit dem neuen Kalander eine Reihe von Vorteilen erzielen. Auch kann man dann eine einzige Hebebühne für beide Walzenstapel verwenden. Dies spart zusätzlichen Bauraum und zusätzliche Wartungsarbeiten.With this configuration, one needs in the direction of web travel only the space of a single calender. This is about twice as high as a single one Roll stack. However, the place in height is in the most of the factories are available anyway because the paper machine also has a relatively large overall height. The position of the winder, such Calender is usually downstream exist so that the building is planned shorter overall or can be held. Paper routing becomes easier. The path between the two roll stacks will be shorter so that the web of material between treatments in the two roller stacks only to a lesser extent is exposed to environmental conditions. A paper web for example, has less time to dry out or cool down. So it can be done with the new calender achieve a number of advantages. You can too then use a single lift for both roll stacks. This saves additional space and additional Maintenance work.

In einer bevorzugten Ausgestaltung ist vorgesehen, daß beide Walzenstapel in einem gemeinsamen Maschinengestell angeordnet sind. Dies vereinfacht den Aufbau. Die beiden Walzenstapel lassen sich leichter zueinander ausrichten. Es ist einfacher, den oberen Walzenstapel entsprechend abzustützen.In a preferred embodiment it is provided that both roll stacks in a common machine frame are arranged. This simplifies the structure. The the two stacks of rollers are easier to match align. It is easier to stack the top roller to support accordingly.

Hierbei ist besonders bevorzugt, daß jeder Walzenstapel fünf Walzen aufweist und das Maschinengestell dem eines 12-Walzen-Kalanders entspricht. In vielen Fällen soll der neue Kalander einen älteren 12-Walzen-Kalander ersetzen. Wenn man die beiden Walzenstapel übereinander anordnet, kann man das Maschinengestell des alten Kalanders in vielen Fällen mitverwenden. Dies bedeutet erhebliche Einsparungen beim Nachrüsten. Darüber hinaus verkürzt sich auch die Umbauzeit auf weniger als die Hälfte, weil man das alte Maschinengestell nicht mehr durch neue Maschinengestelle ersetzen muß. Auch dies ist ein wichtiger Gesichtspunkt im Hinblick auf die Kosten, weil eine kürzere Umbauzeit weniger Stillstand bedeutet.It is particularly preferred that each roll stack has five rollers and the machine frame that one Corresponds to 12-roll calender. In many cases the new calender will replace an older 12-roll calender. If you stack the two rolls on top of each other arranged, you can see the machine frame of the old calender use in many cases. this means considerable savings when retrofitting. Furthermore the conversion time is also reduced to less than that Half because you can no longer use the old machine frame must be replaced by new machine frames. This too is an important consideration with regard to the Costs because a shorter conversion time means less downtime means.

Vorzugsweise sind die Oberwalze des unteren Walzenstapels und die Unterwalze des oberen Walzenstapels auf einer gemeinsamen Lagereinrichtung angeordnet. Trotz der Trennung der beiden Walzenstapel in unterschiedliche Funktionseinheiten, die getrennt voneinander arbeiten können, erreicht man auf diese Weise eine gemeinsame Fixierung und damit einen gemeinsamen Bezugspunkt, mit dessen Hilfe die Steuerung des Betriebes dieses Kalanders vereinfacht werden kann. The upper roller of the lower roller stack is preferably and the lower roll of the upper roll stack arranged a common storage facility. In spite of the separation of the two roll stacks into different ones Functional units that work separately can be achieved in this way Fixation and thus a common reference point, with the help of controlling the operation of this Calender can be simplified.

Vorzugsweise ist zumindest die Unterwalze des oberen Walzenstapels in Lageraufnahmen gelagert, an die sich jeweils eine quer zur Ebene, in der die Walzenachsen des Walzenstapels angeordnet sind, vorstehende Ausrollschiene anschließt. Da die Unterwalzen jeweils als Durchbiegeausgleichswalzen ausgebildet sind, haben sie in der Regel nur relativ kurze Zapfen. Das macht das Aufstecken von Ausbauwerkzeugen schwierig. Es ist schlecht möglich. Wenn man nun die Ausrollschienen an den Lageraufnahmen anordnet, ist es möglich, die Unterwalzen zunächst aus der Ebene des Walzenstapels herauszurollen, bevor man sie dann ergreift. Wenn man sie in der herausgerollten Position ergreift, kann man sie an den übrigen Walzen des Walzenstapels vorbeiführen.Preferably, at least the lower roller is the upper one Rolled stack stored in inventory, to which one each across the plane in which the roller axes of the roll stack are arranged, projecting roll-out rail connects. Since the bottom rollers each as Deflection compensation rollers are formed, they have usually only relatively short cones. It does that Attaching removal tools difficult. It is bad possible. Now if you look at the roll-out rails arranges the bearing mounts, it is possible to use the lower rollers first roll out of the plane of the roll stack, before you take them. If you put them in the rolled out position, you can touch it Guide the remaining rolls of the roll stack.

Mit Vorteil sind zumindest die Zwischenwalzen in Hebeln gelagert. Der Kalander ist also zumindest teilweise als "klassischer" Hebelkalander ausgebildet, so daß die hierfür bekannten und bewährten Steuerungsrezepte verwendet werden können.At least the intermediate rollers in levers are advantageous stored. The calender is at least partially as "Classic" lever calender designed so that the known and proven control recipes used for this can be.

Auch ist von Vorteil, daß ein Materialbahnlaufpfad zwischen der Unterwalze des oberen Walzenstapels und der Oberwalze des unteren Walzenstapels geführt ist. Man kann dann die Materialbahn in beiden Walzenstapeln von unterschiedlichen Seiten her behandeln, ohne daß die Führung der Materialbahn unnötig kompliziert wird. Zwischen der Unterwalze des oberen Walzenstapels und der Oberwalze des unteren Walzenstapels ist sozusagen ein weit offener Wechselspalt gebildet.It is also advantageous that a material web path between the lower roll of the upper roll stack and the The upper roller of the lower roller stack is guided. Man can then the material web in both roll stacks of treat different sides without the Guiding the material web becomes unnecessarily complicated. Between the lower roll of the upper roll stack and the The upper roll of the lower roll stack is, so to speak wide open alternating gap formed.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigt die

einzige Figur
einen Kalander.
The invention is described below with reference to a preferred embodiment in conjunction with the drawing. Herein shows the
only figure
a calender.

Ein Kalander 1 weist zwei Walzenstapel 2, 3 auf, die übereinander an einem gemeinsamen Ständer 4 angeordnet sind.A calender 1 has two roll stacks 2, 3 which arranged one above the other on a common stand 4 are.

Der obere Walzenstapel 2 weist als Oberwalze eine Durchbiegeausgleichswalze 5 auf, deren Durchbiegeausgleichseinrichtung 6 nach unten wirkt, und eine ebenfalls als Durchbiegeausgleichswalze ausgebildete Unterwalze 7, deren Durchbiegeausgleichseinrichtung 8 nach oben wirkt. Zwischen der Oberwalze 5 und der Unterwalze 7 sind drei Zwischenwalzen 9, 10, 11 angeordnet, von denen die Zwischenwalzen 9, 11 beheizt sein können, was durch Heizkanäle im Bereich ihres Umfangs angedeutet ist.The upper roll stack 2 has a top roll Deflection compensation roller 5, the deflection compensation device 6 acts down, and one too Bottom roller designed as a deflection compensation roller 7, the deflection compensation device 8 after acts above. Between the top roller 5 and the bottom roller 7, three intermediate rollers 9, 10, 11 are arranged from which the intermediate rollers 9, 11 can be heated, what indicated by heating channels in the area of their circumference is.

Die Zwischenwalzen 9, 10, 11 sind über Hebel 12, 13, 14 am Ständer 4 befestigt. Die Oberwalze 5 ist am Ständer ortsfest befestigt, während die Unterwalze 7 an einem Schlitten 15 befestigt ist, der mit Hilfe eines Hydraulikzylinders 16 parallel zum Ständer 4 verfahren werden kann. Der Hydraulikzylinder 16 stützt sich hierbei auf einem am Ständer 4 ortsfest angebrachten Lagerelement 17 ab.The intermediate rollers 9, 10, 11 are via levers 12, 13, 14 attached to the stand 4. The top roller 5 is on the stand fixed in place, while the lower roller 7 on one Carriage 15 is attached by means of a hydraulic cylinder 16 can be moved parallel to the stand 4 can. The hydraulic cylinder 16 is based on this a fixed on the stand 4 bearing element 17 onwards.

In üblicher Weise sind mehrere Leitwalzen 18, 19, 20 vorgesehen, mit deren Hilfe eine Materialbahn 21 durch zwischen den einzelnen Walzen 5, 9, 10, 11, 7 gebildete Walzenspalte geführt werden kann, ohne daß es notwendig ist, daß die Materialbahn 21 die entsprechenden Walzen in einem größeren Winkel umschlingt. Die Leitwalzen 18, 19 können hierbei angetrieben sein.Several guide rollers 18, 19, 20 are in the usual way provided with the help of a material web 21 through formed between the individual rollers 5, 9, 10, 11, 7 Nips can be guided without it being necessary is that the web of material 21 the corresponding rollers wrapped at a larger angle. The guide rollers 18, 19 can be driven here.

Der zweite Walzenstapel 3 ist genauso aufgebaut wie der erste Walzenstapel. Die Elemente des Walzenstapels 3, die denen des Walzenstapels 2 entsprechen, sind daher mit um 100 erhöhten Bezugszeichen versehen. The second roll stack 3 is constructed exactly like that first roll stack. The elements of the roll stack 3, which correspond to those of the roll stack 2 are therefore provided with reference numbers increased by 100.

Die Oberwalze 105 des unteren Walzenstapels 3 ist an dem Lagerelement 17 gelagert, an dem sich der Hydraulikzylinder 16 zur Bewegung der Unterwalze 7 des oberen Walzenstapels 2 abstützt.The upper roller 105 of the lower roller stack 3 is on the bearing element 17, on which the hydraulic cylinder 16 for moving the lower roller 7 of the upper Roll stack 2 supports.

Geändert hat sich die Anordnung der Leitwalzen. Die Materialbahn 21 ist durch den zwischen der Unterwalze 7 des oberen Walzenstapels 2 und der Oberwalze 105 des unteren Walzenstapels 3 gebildeten "Wechselspalt" 22 geführt, so daß sie den unteren Walzenstapel 3 praktisch spiegelsymmetrisch zum oberen Walzenstapel 2 durchläuft. Bei identischem Aufbau der Walzenstapel 2, 3 wird die Materialbahn 21 dann auf beiden Seiten praktisch gleich behandelt. Dementsprechend ist die Anordnung der Leitwalzen 118-120 sozusagen um die Walzenebene 23, d.h. die Ebene, in der die Achsen aller Walzen angeordnet sind, geklappt.The arrangement of the guide rollers has changed. The Material web 21 is through the between the lower roller 7th of the upper roll stack 2 and the upper roll 105 of the lower roll stack 3 formed "changing nip" 22nd performed so that they the bottom roll stack 3 practical mirror-symmetrical to the upper roll stack 2 goes through. With identical construction of the roll stack 2, 3, the material web 21 is then practical on both sides treated the same. The arrangement is accordingly the guide rollers 118-120, so to speak, around the roller plane 23, i.e. the plane in which the axes of all the rollers are arranged, folded.

Wie aus der Figur ersichtlich ist, sind die beiden Unterwalzen 7, 107 in Lageraufnahmen 24, 124 gelagert, an die sich jeweils eine Ausrollschiene 25, 125 mit einem Anschlag 26, 126 anschließt. Die Unterwalzen 7, 107 sind im allgemeinen schwierig auszubauen, weil sie nur relativ kurze Walzenzapfen haben, an denen Aufsteckwerkzeuge schwer zu befestigen sind. Mit der dargestellten Ausbildung der Lageraufnahmen 24 ist es jedoch möglich, wie dies für den oberen Walzenstapel 2 mit gestrichelten Linien dargestellt ist, die Unterwalze 7 aus der Lageraufnahme 24 herauszurollen, bis sie zur Anlage an den Anschlag 26 gelangt. Dort kann sie mit Hilfe eines Hebezeugs, das hier durch einen Kranhaken 27 mit Seilen 28 symbolisiert sein soll, ergriffen und abtransportiert werden. Die abtransportierte Walze kann dann auf einem Walzenwagen 29 abgelegt werden. As can be seen from the figure, the two lower rollers 7, 107 stored in camp receptacles 24, 124 which each have a rolling rail 25, 125 with a Stop 26, 126 connects. The lower rollers 7, 107 are generally difficult to expand because they only have relatively short roller journals on which attachments are difficult to attach. With the illustrated Training of the bearing mounts 24, however, is possible, as with the upper roll stack 2 Dashed lines is shown, the lower roller 7th roll out of the bearing holder 24 until it to System comes to the stop 26. There she can join Help of a hoist that is here by a crane hook 27 should be symbolized with ropes 28, seized and be transported away. The removed roller can then placed on a roller carriage 29.

Vor den Walzenstapeln 2, 3, d.h. also auf der dem Ständer 4 abgewandten Seite der Walzenstapel 2, 3, ist eine für beide Walzenstapel gemeinsame Fahrbühne 30 an einem Ständer 31 installiert, so daß die Walzen von dort aus zugänglich sind. Auf der Rückseite sind ebenfalls eine Fahrbühne 32 und gegebenenfalls mehrere Arbeitsbühnen vorgesehen, so daß auch die Rückseite der Walzenstapel 2, 3 für eine Bedienungsperson 33 zugänglich ist.Before the roll stacks 2, 3, i.e. so on the stand 4 facing away from the roll stack 2, 3, is one for both roller stacks common platform 30 on one Stand 31 installed so that the rollers from there are accessible. There are also one on the back Driving platform 32 and possibly several working platforms provided so that the back of the roll stack 2, 3 is accessible to an operator 33.

Als Ständer 4 kann der ausgediente Ständer eines 12-Walzen-Kalanders verwendet werden. Gegebenenfalls muß lediglich die Anordnung der Leitwalzen und die Ausbildung der Hebel geändert werden. Eine derartige Änderung ist aber weitaus problemloser durchzuführen als der Neuaufbau eines neuen Ständers.The used stand of a 12-roll calender can be used as stand 4 be used. If necessary, must only the arrangement of the guide rollers and the training the lever can be changed. Such a change but is far easier to perform than that Rebuild a new stand.
