Description
Die Erfindung bezieht sich auf einen Kalander für eine
Bahn, insbesondere Papierbahn, mit den Merkmalen des
Oberbegriffs des Anspruchs 1.The invention relates to a calender for a
Web, in particular paper web, with the characteristics of
Preamble of
Ein derartiger Kalander ist aus US 4 471 690 A bekannt. Der Kalander ist hier mit fünf Walzen dargestellt, deren Achsen in einer horizontalen Ebene liegen. Die mittlere Walze ist fest. Die jeweils äußeren beiden Walzen sind an Hebeln gelagert, wobei jeder Hebel mit Hilfe eines Luftzylinders so verschwenkt werden kann, daß die Walzen einer Seite aneinander liegen. Der Kalander wird so betrieben, daß entweder die Walzen auf der einen Seite der feststehenden Walze oder die Walzen auf der anderen Seite der feststehenden Walze geschlossene Nips bilden, durch die eine Papierbahn geführt werden kann.Such a calender is known from US 4,471,690 A. The calender is shown here with five rolls, their Axes lie in a horizontal plane. The middle roller is firm. The outer two Rollers are mounted on levers, each lever with Can be pivoted with the help of an air cylinder that the rollers on one side lie against each other. The calender is operated so that either the rollers on one side of the fixed roller or the rollers closed on the other side of the fixed roller Form nips through which a paper web is passed can be.
Kalander der üblichen Bauart weisen einen Stapel aus übereinander angeordneten Walzen mit horizontaler Achse auf. Sie dienen der Behandlung von Papier, Pappe, Kunststoff-Folie und ähnlichem Material. Die Walzenspalte sind entweder durch harte Walzen oder - insbesondere bei der Papierveredelung - auf der einen Seite durch eine harte Walze und auf der anderen Seite durch eine weiche Walze begrenzt. Die Streckenlast in den Walzenspalten wird zum einen durch hydraulische Kraftgeber, die an einer Endwalze angreifen, und zum anderen durch das Gewicht der Walzen bestimmt. Die Streckenlast und damit die Druckspannung nimmt daher von oben nach unten zu. Dies bedeutet, daß der Variationsbereich der von den Kraftgebern aufbringbaren Kräfte verhältnismäßig klein ist. Eine Begrenzung nach oben ergibt sich, weil das Bahnmaterial im untersten Spalt zu stark belastet wird. Eine Begrenzung nach oben ergibt sich, weil das Bahnmaterial im obersten Spalt keine Verformung mehr erfährt.Calenders of the usual design have a stack rollers arranged one above the other with a horizontal axis on. They are used to treat paper, cardboard, Plastic film and similar material. The nip are either by hard rolling or - in particular in paper finishing - on one side through a hard roller and on the other side limited a soft roller. The line load in the On the one hand, roll nips are created by hydraulic power transmitters, who attack one end roller and the other determined by the weight of the rollers. The line load and therefore the compressive stress increases from the top down to. This means that the range of variation of the forces which can be applied by the force transmitters are proportional is small. There is an upper limit, because the web material in the lowest gap is too heavily loaded becomes. There is an upper limit because the web material in the top gap no deformation learns more.
Bei einem Kalander dieser üblichen Art, wie er in WO 95/14813 beschrieben ist, sind die Endwalzen als Biegeeinstellwalzen ausgeführt und die Mittelwalzen an Hebeln gelagert, an denen Vorrichtungen zur Krafteinleitung angreifen. Die Walzen sind so ausgelegt, daß die durch die eigene Schwerkraft erzeugten natürlichen Biegelinien im wesentlichen gleich sind. Ferner wird die Spaltbelastung, die durch die Massen der Mittelwalzen und der zugehörigen Hilfseinrichtungen erzeugt wird, durch die Vorrichtungen zur Krafteinleitung im wesentlichen vollständig aufgehoben. Theoretisch kann hierdurch der gesamte Schwerkrafteinfluß ausgeschaltet werden. Praktisch bereitet es aber außerordentliche Schwierigkeiten, die genannten Bedingungen zu erfüllen. Haben nämlich nicht alle Walzen etwa die gleiche Eigendurchbiegung durch ihr Eigengewicht, kommt es im Betrieb zu höheren Druckbelastungen an den Walzenrändern oder in der Walzenmitte.With a calender of this usual type, as in WO 95/14813 is described, the end rolls are as Bending adjustment rollers executed and the center rollers on Levers mounted on the devices for force application attack. The rollers are designed so that the natural ones created by gravity Bending lines are essentially the same. Furthermore, the gap load caused by the masses of the center rolls and the associated auxiliary devices is through the devices for force introduction in essentially completely canceled. Theoretically can this eliminates the entire influence of gravity become. In practice, however, it prepares extraordinary Difficulties in meeting the above conditions. Not all rollers have approximately the same inherent deflection due to their own weight, it occurs in the company to higher pressure loads on the roller edges or in the middle of the roller.
Im Gegensatz hierzu sind bei dem aus DE 26 03 484 A1 oder DE 26 03 485 A1 bekannten Kalander die Walzen mit horizontaler Achse nebeneinander angeordnet, so daß der Gewichtseinfluß der Walzen auf die Streckenlast vollständig entfällt. Die Walzen sind in Lagerblöcken gehalten, die längs einer Führung verschoben werden können. Die eine Endwalze ist ortsfest gelagert, die andere wird durch Kraftgeber in der Form von Kolben-Zylinder-Einheiten in Richtung auf die andere Endwalze belastet. Bei diesem Kalander herrscht in allen Walzenspalten die gleiche Streckenlast.In contrast, the from DE 26 03 484 A1 or DE 26 03 485 A1 known calenders the rolls with horizontal Axis arranged side by side so that the Weight influence of the rollers on the line load completely eliminated. The rollers are held in bearing blocks, that can be moved along a guide. One end roller is stationary, the other is made by force transducers in the form of piston-cylinder units towards the other end roller. This calender is used in all nips the same line load.
US 4 519 757 A zeigt einen Kalander mit fünf Walzen, deren Achsen in einer horizontalen Ebene nebeneinander angeordnet sind. Die beiden äußeren Walzen sind an Hebeln gelagert und durch Vorrichtungen zur Krafteinleitung beaufschlagt. Die mittlere Walze liegt fest. Die zwischen der mittleren Walze und der jeweils äußeren Walze liegenden Zwischenwalzen sind jeweils auf Gleitführungen gelagert.US 4,519,757 A shows a calender with five rolls, their axes side by side in a horizontal plane are arranged. The two outer rollers are on levers stored and by means of force introduction applied. The middle roller is fixed. The between the middle roller and the outer roller Roller intermediate rollers are each on sliding guides stored.
Der Erfindung liegt die Aufgabe zugrunde, einen Kalander der eingangs beschriebenen Art anzugeben, der in den einzelnen Walzenspalten mit unterschiedlicher Streckenlast betrieben werden kann.The invention has for its object a calender of the type described in the introduction, which in the individual nips with different Line load can be operated.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale
des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features
of the characterizing part of
Bei dieser Konstruktion kann in jedem Walzenspalt die gewünschte Streckenlast eingestellt werden, indem die Hebel mittels der Vorrichtungen zur Krafteinleitung belastet werden. Diese Vorrichtungen werden angewendet, obwohl sie für ihren bekannten Zweck, nämlich die Gewichtsentlastung, nicht erforderlich sind. Die endseitigen Biegeeinstellwalzen unterstützen die Einstellung der Streckenlast und ermöglichen insbesondere eine Vergleichmäßigung in Richtung der Bahnbreite. Die Vorrichtungen zur Krafteinleitung sind zweiseitig wirksam. In der einen Wirkungsrichtung dienen sie der Streckenlast-Erzeugung oder -Erhöhung, in der anderen Wirkungsrichtung der Streckenlast-Reduzierung und gegebenenfalls einer Schnelltrennung der Walzen.With this construction, the desired line load can be set by the Lever loaded by means of the force introduction devices become. These devices are used although for its well-known purpose, namely weight relief, are not required. The end Bending adjustment rollers support the adjustment the line load and, in particular, allow a leveling in the direction of the web width. The devices to apply force are bilateral. In in one direction of action they serve to generate line load or increase, in the other direction the line load reduction and if necessary a quick separation of the rollers.
Besonders günstig ist es, daß zur Erzeugung einer in allen Walzenspalten gleichen Grund-Streckenlast die eine Endwalze durch Kraftgeber in Richtung auf die andere Endwalze belastbar ist. Da das Walzengewicht für die Streckenlast keine Rolle spielt, kann die Grund-Streckenlast, die durch die Kraftgeber aufgebracht wird, innerhalb eines großen Bereichs frei gewählt werden. Insbesondere kann bereits im ersten Walzenspalt eine verhältnismäßig große Streckenlast vorherrschen. Da die Vorrichtungen zur Krafteinleitung lediglich Zusatzkräfte aufbringen müssen, können sie vergleichsweise klein ausgeführt werden.It is particularly favorable that in order to generate a all roller nips have the same basic line load End roller by force transducer towards the other End roller is resilient. Since the roller weight for the Line load does not matter, the basic line load, which are applied by the force givers will be chosen freely within a wide range. In particular, can already in the first nip there is a relatively large line load. Since the force introduction devices only additional forces they can muster comparatively run small.
Von Vorteil ist es auch, daß für die Walzen jeweils eigene Antriebe vorgesehen sind, die seitliche Ausbiegungen der Walzen verhindern. Solche Ausbiegungen treten immer dann auf, wenn eine einzige angetriebene Walze die anderen Walzen durch Friktion mitnimmt.It is also advantageous that each for the rollers Drives are provided, the side bends prevent the rollers. Such bends occur whenever there is a single driven roller takes the other rollers with friction.
Bei einer bevorzugten Ausführungsform ist dafür gesorgt, daß das die Walzen tragende Gestell aus einer Betriebsstellung, in der die Walzenachsen in der horizontalen Ebene liegen, in eine Ruhestellung verlagerbar ist, in der die Walzenachsen in einer vertikalen Eben übereinander angeordnet sind. In dieser Ruhestellung läßt sich die Materialbahn in üblicher Weise in die Walzenspalte einführen. Für den Betrieb wird dann der Kalander in die Betriebsstellung geschwenkt.In a preferred embodiment, it is ensured that that the frame supporting the rollers from a Operating position in which the roller axes are in the horizontal Lying level, shiftable to a rest position is in which the roller axes are in a vertical plane are arranged one above the other. In this rest position can the web of material in the usual way Insert the nip. Then the Calender pivoted into the operating position.
Als besonders einfache Lösung wird eine horizontale Schwenkachse vorgesehen, um die das Gestell um 90° schwenkbar ist.A horizontal solution is a particularly simple solution Swivel axis provided around which the frame by 90 ° is pivotable.
Empfehlenswert ist es, daß mindestens eine Wickelstation über einen gemeinsamen Support mit dem Gestell verbunden ist. Wickelstation und Kalander werden daher gemeinsam verschwenkt.It is recommended that at least one winding station connected to the frame via a joint support is. The winding station and the calender therefore become one pivoted.
Eine Alternative besteht darin, daß mindestens eine ortsfeste Wickelstation einen Wickel mit horizontaler Achse aufweist und zwischen ihr und dem Walzenstapel mindestens eine Leitwalze mit horizontaler Achse angeordnet ist, die erst beim Verlagern des Gestells aus der Ruhestellung in die Betriebsstellung von der Bahn kontaktiert wird. Hier braucht lediglich der Kalander verschwenkt zu werden.An alternative is that at least one stationary winding station a winding with horizontal Has axis and between it and the roll stack at least one guide roller arranged with a horizontal axis which is only off when the frame is moved the rest position in the operating position from the train is contacted. Only the calender is needed here to be pivoted.

Der Kalander der Fig. 1 weist ein Gestell 1 auf, welches
Teil eines Supports 2 ist, der eine Abwickelstation
3 für einen Wickel 4 und eine Aufwickelstation 5 für
einen Wickel 6 trägt. Der Kalander weist einen Stapel
von acht Walzen 7 bis 14 auf, die nebeneinander in einer
horizontalen Ebene angeordnet sind. Die beiden Endwalzen
7 und 14 sind Biegeeinstellwalzen, wie dies
durch hydraulisch betätigbare Stützelemente 15 und 16
angedeutet ist. Bei den Mittelwalzen gibt es zwei beheizbare
Walzen 9 und 12 aus Hartguß mit peripher angeordneten
Heizmittelkanälen 17 und vier mit einem elastischen
Belag versehene Walzen 8, 10, 11 und 13. Eine
Papierbahn 18 durchläuft die so gebildeten Walzenspalte

Die Endwalze 7 ist am Gestell 1 abgestützt. Die Endwalze
14 wird durch Kraftgeber 20 in der Form von Kolben-Zylinder-Einheiten
in Richtung auf die andere Endwalze
7 belastet. Dies ergibt eine Grund-Streckenlast in den
Spalten zwischen den einzelnen Walzen.The end roller 7 is supported on the
Alle Mittelwalzen 8 bis 13 werden von Hebeln 21 getragen,
die um horizontale Achsen 22 schwenkbar sind, und
durch Vorrichtungen 23 in der Form von Kolben-Zylinder-Einheiten,
die zweiseitig wirksam sind, belastet. Außerdem
besitzt jede der Walzen 7 bis 14 einen eigenen
Antrieb, was in der Zeichnung nicht dargestellt ist.All middle rollers 8 to 13 are supported by
Betrachtet man beispielsweise den Walzenspalt 24 zwischen
den Walzen 7 und 8, so kann die durch die Kraftgeber
20 erzeugte Grund-Streckenlast durch Aufbringen
einer Kraft mittels der zugehörigen Vorrichtung 23 in
der einen Richtung zu einer Erhöhung der Streckenlast
und in der anderen Richtung zu einer Verringerung der
Streckenlast führen. Die letztgenannte Kraftrichtung
kann auch zum Trennen der Walzen benutzt werden, wenn
die Endwalze 14 ganz nach links gefahren wird und die
übrigen Walzen jeweils über ein Stück des Wegs folgen.For example, consider the nip 24 between
the rollers 7 and 8, so that by the

um die er aus der Betriebsstellung um 90° in eine Ruhestellung
schwenkbar ist, so daß das Gestell 1 zusammen

dieser Ruhestellung kann die Papierbahn 18 in üblicher
Weise von oben nach unten eingezogen werden.The support 2 has a
Bei der Ausführungsform nach den Fig. 2 und 3 werden
für entsprechende Teile um 100 erhöhte Bezugszeichen
verwendet. Unterschiedlich ist im wesentlichen, daß die
Abwickelstation 103 und die Aufwickelstation 105 ortsfest
angeordnet sind und nur das Gestell 101 des Kalanders
um eine Schwenkachse 125 um 90° schwenkbar ist.
Zur Aufwickelstation gehört noch ein Rollenschneider
126. Der Walzenstapel besteht aus den beiden Endwalzen
107 und 114, die wiederum als Biegeeinstellwalzen ausgebildet
sind, und aus vier Mittelwalzen 108 bis 111,
die an Hebeln 121 gelagert sind, welche um horizontale
Schwenkachsen 122 schwenkbar und durch Vorrichtungen
123 zur Krafteinleitung belastbar sind.In the embodiment according to FIGS. 2 and 3
for corresponding parts, reference numbers increased by 100

von Leitwalzen 119 geführt. Speziell verwiesen sei auf
eine Leitwalze 127, die erst wirksam wird, wenn das Kalandergestell
