Definitions
- the invention relates to a calender with the features of the preamble of claim 1.
- Such a calender is known for example from the earlier German patent application 195 OB 353.
- Such calenders have the advantage that one can treat the two sides of a material web, for example a paper web, with practically identical results.
- the total number of rolls can be kept lower than in a conventional multi-roll calender typically equipped with twelve rolls.
- the control of compressive stresses in the individual nips can be done with higher degrees of freedom.
- the invention has for its object to build a calender above possible cost or simply to be able to retrofit.
- At least the lower roller of the upper roller stack is mounted bearing receptacles, to each of which a transversely to the plane in which the roller axes of the roller stack are arranged, projecting Ausrollschiene connects. Since the lower rollers are each formed as a deflection compensating rollers, they usually have only relatively short pin. This makes the attachment of removal tools difficult. It is badly possible. Now, if one arranges the Ausrollschienen to the bearing mounts, it is possible to first roll out the lower rollers from the plane of the roll stack before they then takes. If you take them in the rolled-out position, you can pass them by the other rolls of the roll stack.
- both roll stacks are arranged in a common machine frame. This simplifies the structure.
- the two roll stacks are easier to align with each other. It is easier to support the upper roll stack accordingly.
- each roll stack has five rolls and the machine frame corresponds to that of a 12-roll calender.
- the new calender will replace an older 12-roll calender. If you put the two stack of rolls on top of each other, you can use the machine frame of the old calender in many cases. This means considerable savings in retrofitting.
- the conversion time is reduced to less than half, because you no longer have to replace the old machine frame with new machine frames. Again, this is an important consideration in terms of cost because a shorter conversion time means less downtime.
- the upper roll of the lower roll stack and the lower roll of the upper roll stack are arranged on a common storage device.
- a common fixation and thus a common reference point with the aid of which the control of the operation of this calender can be simplified.
- At least the intermediate rollers are mounted in levers.
- the calender is thus at least partially designed as a "classic" Hebelkalander so that the known and proven control recipes can be used for this purpose.
- a calender 1 has two roll stacks 2, 3, which are arranged one above the other on a common stand 4.
- the upper roll stack 2 has, as a top roll, a deflection compensating roll 5, whose deflection compensation device 6 acts downward, and a bottom roll 7, also designed as a deflection roll, whose deflection compensation device 8 acts upwards. Between the upper roller 5 and the lower roller 7, three intermediate rollers 9, 10, 11 are arranged, of which the intermediate rollers 9, 11 may be heated, which is indicated by heating channels in the region of its circumference.
- the intermediate rollers 9,10,11 are mounted on the stand 4 via levers 12, 13, 14.
- the upper roller 5 is fixedly mounted on the stand, while the lower roller 7 is fixed to a carriage 15 which can be moved by means of a hydraulic cylinder 16 parallel to the stator 4.
- the hydraulic cylinder 16 is supported in this case on a stator 4 fixedly mounted bearing element 17 from.
- a plurality of guide rollers 18, 19, 20 are provided, by means of which a material web 21 can be guided by formed between the individual rollers 5, 9, 10, 11, 7 nips, without it being necessary that the material web 21 the corresponding rollers wrapped at a larger angle.
- the guide rollers 18, 19 can be driven in this case.
- the second roll stack 3 has the same structure as the first roll stack.
- the elements of the roll stack 3, which correspond to those of the roll stack 2, are therefore provided with reference numerals increased by 100.
- the upper roll 105 of the lower roll stack 3 is mounted on the bearing element 17, on which the hydraulic cylinder 16 is supported for moving the lower roll 7 of the upper roll stack 2.
- the material web 21 is guided by the formed between the lower roller 7 of the upper roll stack 2 and the upper roll 105 of the lower roll stack 3 "interchangeable gap" 22 so that it passes through the lower roll stack 3 practically mirror-symmetrical to the upper roll stack 2.
- the material web 21 is then treated on both sides practically the same. Accordingly, the arrangement of the guide rollers 118-120 is, so to speak, around the roller plane 23, i. The plane in which the axes of all rollers are arranged, folded.
- the two lower rollers 7,107 are mounted in bearing receptacles 24,124, to each of which a roll-bar 25, 125 with a stop 26, 126 connects.
- the bottom rollers 7, 107 are generally difficult to disassemble because they have only relatively short roll necks where attachment tools are difficult to attach.
- the bearing receivers 24 With the illustrated embodiment of the bearing receivers 24, however, it is possible, as shown for the upper roll stack 2 with dashed lines, the lower roller 7 to roll out of the bearing receptacle 24 until it comes to rest against the stop 26. There she can with the help of a hoist, which is to be symbolized by a crane hook 27 with ropes 28, taken and transported away. The removed roller can then be stored on a roller carriage 29.
- roller stacks 2, 3 In front of the roller stacks 2, 3, i. Thus, on the side facing away from the stand 4 of the roll stack 2, 3, a common platform for both rollers 30 is installed on a stand 31, so that the rollers are accessible from there. On the back of a rideway 32 and possibly several working platforms are provided so that the back of the roll stack 2, 3 for an operator 33 is accessible.
- the old stand of a 12-roll calender can be used. If necessary, only the arrangement of the guide rollers and the formation of the lever must be changed. However, such a change is much easier to carry out than the rebuilding of a new stand.

Description
Die Erfindung betrifft einen Kalander mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a calender with the features of the preamble of claim 1.
Ein derartiger Kalander ist beispielsweise aus der älteren deutschen Patentanmeldung 195 OB 353 bekannt.Such a calender is known for example from the earlier German patent application 195 OB 353.
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 typischeweise mit zwölf Walzen ausgerüstet war. Die Steuerung der Druckspannungen in den einzelnen Walzenspalten kann mit höheren Freiheitsgraden erfolgen.Such calenders have the advantage that one can treat the two sides of a material web, for example a paper web, with practically identical results. The total number of rolls can be kept lower than in a conventional multi-roll calender typically equipped with twelve rolls. The control of compressive stresses in the individual nips can be done with higher degrees of freedom.
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 formation of the calender with two separately working roller stacks has an increased space requirement. In addition, two new calender stands are necessary, which, as is apparent from the German patent application 195 08 353, are arranged so that the rolling levels, i. the planes in which the axes of the rollers forming a roll stack are arranged are arranged parallel and behind one another. Both result in increased investment costs. A retrofit is due to a limited space in some cases not possible.
Der Erfindung liegt die Aufgabe zugrunde, einen obengenannten Kalander möglichst kostengünstig bauen oder einfach nachrüsten zu können.The invention has for its object to build a calender above possible cost or simply to be able to retrofit.
Diese Aufgabe wird bei einem Kalander der eingangs genannten Art mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved in a calender of the type mentioned with the features of the characterizing part of claim 1.
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, well 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 belspielsweise 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. Zumindest die Unterwalze des oberen Walzenstapels ist 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.With this configuration, you only need the space of a single calender in the web running direction. Although this is about twice as high as a single roll stack. However, the height of the place is already available in most production halls anyway, because the paper machine also has a relatively large overall height. The position of the winding, which is usually downstream of such a calender, remains in place, so that the building can be planned or held altogether shorter. The paper guide becomes easier. The path between the two roll stacks is shorter, so that the material web is exposed to the environmental conditions between the treatments in the two roll stacks only to a lesser extent. For example, a paper web has less time to dry out or cool down. So it can be achieved with the new calender a number of advantages. Also, one can then use a single lift for both roll stacks. This saves additional space and additional maintenance. At least the lower roller of the upper roller stack is mounted bearing receptacles, to each of which a transversely to the plane in which the roller axes of the roller stack are arranged, projecting Ausrollschiene connects. Since the lower rollers are each formed as a deflection compensating rollers, they usually have only relatively short pin. This makes the attachment of removal tools difficult. It is badly possible. Now, if one arranges the Ausrollschienen to the bearing mounts, it is possible to first roll out the lower rollers from the plane of the roll stack before they then takes. If you take them in the rolled-out position, you can pass them by the other rolls of the roll stack.
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 are arranged in a common machine frame. This simplifies the structure. The two roll stacks are easier to align with each other. It is easier to support the upper roll stack 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 rolls and the machine frame corresponds to that of a 12-roll calender. In many cases, the new calender will replace an older 12-roll calender. If you put the two stack of rolls on top of each other, you can use the machine frame of the old calender in many cases. This means considerable savings in retrofitting. In addition, the conversion time is reduced to less than half, because you no longer have to replace the old machine frame with new machine frames. Again, this is an important consideration in terms of cost because a shorter conversion time means less downtime.
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 voneinanderarbeiten 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.Preferably, the upper roll of the lower roll stack and the lower roll of the upper roll stack are arranged on a common storage device. Despite the separation of the two stack of rollers in different functional units that can work separately, one achieves in this way a common fixation and thus a common reference point, with the aid of which the control of the operation of this calender can be simplified.
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.Advantageously, at least the intermediate rollers are mounted in levers. The calender is thus at least partially designed as a "classic" Hebelkalander so that the known and proven control recipes can be used for this purpose.
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 running path is guided between the lower roll of the upper roll stack and the upper roll of the lower roll stack. It is then possible to treat the material web in both roll stacks from different sides, without the guidance of the material web being unnecessarily complicated. Between the lower roller of the upper roller stack and the upper roller of the lower roller stack, so to speak, a wide open alternating gap is 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 will be described below with reference to a preferred embodiment in conjunction with the drawings. Here the single figure shows 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
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
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
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.In a conventional manner, a plurality of
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
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
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.Has changed the arrangement of the guide rollers. The
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 hierdurch 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 are mounted in bearing receptacles 24,124, to each of which a roll-
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.In front of the roller stacks 2, 3, i. Thus, on the side facing away from the stand 4 of the
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. As a stand 4, the old stand of a 12-roll calender can be used. If necessary, only the arrangement of the guide rollers and the formation of the lever must be changed. However, such a change is much easier to carry out than the rebuilding of a new stand.
