Description

Presswalze mit einem Walzenmantel Press roll with a roll jacket
Die Erfindung betrifft eine Presswalze mit einem Walzenmantel, der an Tragscheiben befestigt, drehbar auf einem stationären Träger gelagert und in axialer Richtung auf dem Träger verschiebbar ist, wobei der Walzenmantel durch eine Spannvorrichtung, die an den Tragscheiben angreift, unter Zugspannung gesetzt werden kann.The invention relates to a press roll with a roll shell which is attached to support disks, rotatably mounted on a stationary support and is axially displaceable on the support, the roll cover being able to be placed under tension by a tensioning device which acts on the support disks.
Derartige im Stand der Technik bekannte Presswalzen werden in Verbindung mit Gegenwalzen zum Entwässern einer Faserstoffbahn, insbesondere einer Papier- oder Zellstoffbahn verwendet, indem die zu entwässernde Faserstoffbahn, gegebenenfalls parallel mit einer zur Aufnahme von ausgepresstem Wasser geeigneten Bahn aus Filz oder dergleichen, zwischen der drehangetriebenen Gegenwalze und dem frei mitlaufenden Walzenmantel durchgeführt wird. Um die wirksame Fläche zwischen der Gegenwalze und dem Walzenmantel zu vergrößern und die Entwässerung zu verbessern, ist innerhalb des Walzenmantels ein Pressschuh angeordnet, mit dessen Hilfe der Walzenmantel gegen die Gegenwalze gepresst wird. Aufgrund des hohen Druckes, mit dem der Pressschuh auf den Walzenmantel einwirkt, unterliegt die Innenfläche des Walzenmantels einem nicht unerheblichen Verschleiß, so dass der Walzenmantel in Achsrichtung auf dem Pressschuh verschiebbar ist, um die Belastung des Walzenmantels gleichmäßig über dessen gesamte Länge zu verteilen.Such press rollers known in the prior art are used in connection with counter-rollers for dewatering a fibrous web, in particular a paper or cellulose web, by the fibrous web to be dewatered, optionally in parallel with a web of felt or the like suitable for taking out squeezed water, between the rotating drives Counter roll and the free running roller jacket is carried out. In order to increase the effective area between the counter roller and the roller shell and to improve the dewatering, a press shoe is arranged inside the roller shell, with the aid of which the roller shell is pressed against the counter roller. Due to the high pressure with which the press shoe acts on the roll casing, the inner surface of the roll casing is subject to considerable wear, so that the roll casing can be displaced in the axial direction on the press shoe in order to distribute the load on the roll casing evenly over its entire length.
Diese Verstellung wird im Stand der Technik zum Beispiel mit Druckfedern und Spindeln oder mit zwei innerhalb des Walzenmantels angeordneten Hydraulikzylindern durchgeführt. Bei der Spindelverstellung erfolgt dies durch Verdrehen der Spindel außerhalb der Presseinheit. Bei der hydraulischen Verstellung ist ein relativ aufwändiges Steuerprogramm erforderlich, da die Hydraulikzylinder doppelt wirkend sind, und die Steuerung aufgrund der unterschiedlichen boden- und kolbenstangen- seitigen Fläche die daraus resultierenden, unterschiedlichen Verstellkräfte genau berücksichtigen muss. Der Erfindung liegt die Aufgabe zugrunde, das Verstellen des Walzenmantels der Presswalze einfacher zu gestalten.In the prior art, this adjustment is carried out, for example, with compression springs and spindles or with two hydraulic cylinders arranged inside the roll shell. When adjusting the spindle, this is done by turning the spindle outside the press unit. A relatively complex control program is required for hydraulic adjustment, since the hydraulic cylinders are double-acting and the control system must take the resulting different adjustment forces into account due to the different surface on the bottom and piston rod side. The invention has for its object to make the adjustment of the roll shell of the press roll easier.
Gelöst wird diese Aufgabe mit einer Presswalze mit den Merkmalen des Anspruches 1. Bei der Erfindung wird die Vorspannung des Walzenmantels und die Verstellung durch eine Kombination aus wenigstens einer, vorzugsweise mehreren, Druckfedern und wenigstens einem, vorzugsweise mehreren, Druckmittelzylindem bewirkt, indem die Druckmittelzylinder einerseits die Druckfedern unter Vorspannung setzen und andererseits gleichzeitig auch die Verschiebung des Walzenmantels bewerkstelligen. Die Position des Walzenmantels kann in diesem Fall sehr einfach, z.B. mit Hilfe eines beispielsweise dem Hydraulikzylinder zugeordneten Wegmeßsystems, eingestellt werden. Dies ist aber auch mit Hilfe eines Druckmeßsystems möglich, das den Druck im Hydraulikzylinder bzw. Hydraulik- System misst, da die Federkennlinie der Druckfedem bekannt ist und im wesentlichen linear sein kann, so dass die Position des Walzenmantels über den Hydraulikdruck entsprechend der Federkennlinie genau bestimmt werden kann.This object is achieved with a press roller with the features of claim 1. In the invention, the pretensioning of the roller shell and the adjustment are brought about by a combination of at least one, preferably more, pressure springs and at least one, preferably more, pressure medium cylinders, by the pressure medium cylinders on the one hand place the compression springs under prestress and, on the other hand, at the same time also bring about the displacement of the roll shell. The position of the roll shell can be very simple in this case, e.g. with the aid of a position measuring system assigned to the hydraulic cylinder, for example. However, this is also possible with the aid of a pressure measuring system which measures the pressure in the hydraulic cylinder or hydraulic system, since the spring characteristic of the compression spring is known and can be essentially linear, so that the position of the roller shell is determined precisely via the hydraulic pressure in accordance with the spring characteristic can be.
Ein weiterer Vorteil, der sich aufgrund der Erfindung ergibt, ist der, dass der Walzenmantel, z. B. für einen Mantelwechsel, sehr einfach entspannt werden kann, indem der bzw. die Druckmittelzylinder entspannt werden, da sich der Walzenmantel durch die Druckfeder(n) dann automatisch in eine vorgegebene Ruheposition bewegt.Another advantage that results from the invention is that the roll shell, for. B. for a jacket change, can be relaxed very easily by relaxing the pressure medium cylinder (s), since the roller jacket then automatically moves into a predetermined rest position by the compression spring (s).
Bevorzugte Ausgangsformen der Erfindung sind Gegenstand der Unteransprüche.Preferred starting forms of the invention are the subject of the dependent claims.
Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung mit Bezugnahme auf die beiliegenden Zeichnungen beschrieben. Es zeigt Fig. 1 einen Achsialschnitt durch eine erfindungsgemäße Presswalze, Fig. 2 einen Schnitt durch die Presswalze von Fig. 1 entlang der Linie ll/ll, Fig. 3 einen Ausschnitt der Presswalze von Fig. 1 im Bereich eines Druckmittelzylinders in vergrößertem Maßstab und Fig. 4 eine schematische Darstellung der erfindungsgemäßen Anordnung entsprechend Fig. 1. In Fig. 1 ist im Längsschnitt eine erfindungsgemäße Presswalze dargestellt, die einen Walzenmantel 1 , einen stationären Träger 2 und einen Pressschuh 3 aufweist. Der Pressschuh 3 ist auf dem Träger 2 befestigt. Der Walzenmantel 1 wird durch eine nicht dargestellte Gegen- walze gegen den Pressschuh gedrückt.A preferred embodiment of the invention is described below with reference to the accompanying drawings. 1 shows an axial section through a press roll according to the invention, FIG. 2 shows a section through the press roll from FIG. 1 along the line II / II, FIG. 3 shows a detail of the press roll from FIG. 1 in the region of a pressure medium cylinder on an enlarged scale and 4 shows a schematic illustration of the arrangement according to the invention corresponding to FIG. 1. In Fig. 1, a press roll according to the invention is shown in longitudinal section, which has a roll shell 1, a stationary support 2 and a press shoe 3. The press shoe 3 is fastened on the carrier 2. The roll shell 1 is pressed against the press shoe by a counter roll, not shown.
Der Walzenmantel 1 ist über Tragscheiben 4 am Träger 2 gelagert, wobei die Tragscheiben 4 im wesentlichen aus einem innenring 5 und einem Außenring 6 bestehen, die über ein Wälzlager 7 gegeneinander drehbar sind. Die Innenringe 5 der Tragscheiben 4 sind auf Gleithülsen 8 verschiebbar gelagert, wobei die Gleithülsen 8 selbst unverschiebbar am Träger 2 befestigt sind.The roller shell 1 is supported on the carrier 2 via support disks 4, the support disks 4 essentially consisting of an inner ring 5 and an outer ring 6, which can be rotated relative to one another via a roller bearing 7. The inner rings 5 of the support disks 4 are slidably mounted on sliding sleeves 8, the sliding sleeves 8 themselves being fixed immovably on the carrier 2.
Durch synchrones Verschieben der Tragscheiben 4 in Richtung des Doppelpfeils 9 kann der Walzenmantel 1 relativ zum Pressschuh 3 verschoben werden, so dass die durch das Anpressen des Pressschuhs 3 auf den Walzenmantel 1 entstehende Belastung auf die gesamte Länge des Walzenmantels 1 verteilt werden kann, indem der Walzenmantel 1 kontinuierlich oder in periodischen Abständen entlang des Doppelpfeils 9 hin- und herbewegt wird.By synchronously moving the support disks 4 in the direction of the double arrow 9, the roller shell 1 can be displaced relative to the press shoe 3, so that the load resulting from the pressing of the press shoe 3 on the roller shell 1 can be distributed over the entire length of the roller shell 1 by the Roll jacket 1 is moved back and forth continuously or at periodic intervals along the double arrow 9.
Für ein ordnungsgemäßes Funktionieren der Presswalze ist es erforderlich, das der Walzenmantel 1 in Richtung der Achse 10 ständig unter Zugspannung steht. Um einerseits diese Zugspannung aufrecht zu erhalten, und andererseits das Verschieben des Walzenmantels 1 zu bewerkstelligen, ist gemäß der Erfindung eine Spannvorrichtung bestehend aus Druckfedern 11 und Druckmittelzylindem 12 vorgesehen. Die Druckfedern 11 und Druckmittelzylinder 12 sind einerseits am Träger 2 befestigt, und anderseits an Druckringen 13, wobei sich die Druckringe 13 an den Innenringen 5 der Tragscheiben 4 abstützen. Die Druckfedern 11 sind im Betrieb auf Druck vorgespannt. Die Druckmittelzylinder 12 können in ihrer einfachsten Ausführungsform einfach wirkende Druckmittelzylinder sein, die im Betrieb ebenfalls eine Druckkraft zwischen dem Träger 2 und dem Druckring 13 aufbringen. Durch Erhöhen oder Verringern des Druckes in den Druckmittelzylinder 12 erfolgt entsprechend der Feder- kennlinie der Druckfedern 11 eine Verschiebung des Walzenmantels in Richtung des Doppelpfeils 9.For the press roll to function properly, it is necessary for the roll casing 1 to be constantly under tension in the direction of the axis 10. In order on the one hand to maintain this tension and on the other hand to bring about the displacement of the roll shell 1, a tensioning device consisting of compression springs 11 and pressure medium cylinders 12 is provided according to the invention. The compression springs 11 and pressure medium cylinders 12 are fastened on the one hand to the carrier 2 and on the other hand to pressure rings 13, the pressure rings 13 being supported on the inner rings 5 of the support disks 4. The compression springs 11 are biased to pressure during operation. In their simplest embodiment, the pressure medium cylinders 12 can be single-acting pressure medium cylinders, which also apply a pressure force between the carrier 2 and the pressure ring 13 during operation. By increasing or decreasing the pressure in the pressure medium cylinder 12, the spring Characteristic curve of the compression springs 11 a displacement of the roller shell in the direction of the double arrow 9.
Durch diese sehr einfache technische Ausführungsform der Erfindung kann auch die Steuerung für das Verstellen des Walzenmantels 1 sehr einfach ausgeführt sein. Es ist beispielsweise möglich mit dem Druckmittelzylinder 12 ein Wegmesssystem 14 zu verbinden, so dass die Position des Druckmittelzylinders 12 und somit auch die Position des Walzenmantels 1 einfach eingestellt werden kann.Due to this very simple technical embodiment of the invention, the control for adjusting the roll shell 1 can also be carried out very simply. For example, it is possible to connect a displacement measuring system 14 to the pressure medium cylinder 12 so that the position of the pressure medium cylinder 12 and thus also the position of the roller shell 1 can be easily adjusted.
Da eine ausreichende Vorspannung des Walzenmantels 1 durch die Druckfedern 11 immer gewährleistet ist, braucht keine zusätzliche Steuerung vorgesehen sein, welche die Spannung des Walzenmantels 1 aufrecht erhält.Since sufficient prestressing of the roll shell 1 is always ensured by the compression springs 11, no additional control that maintains the tension of the roll shell 1 needs to be provided.
Wie in den Fig. 1 und 2 zu erkennen ist, sind im dargestellten Ausführungsbeispiel vier Druckfedern 11 in einem Winkelabstand von 90° zueinander angeordnet. Weiters sind zwei Hydraulikzylinder 12 vorgesehen, die einander bezüglich der Achse 10 gegenüber liegen. Bezüglich der Druckfedern 11 sind die Hydraulikzylinder um 45° versetzt angeordnet. Die Hydraulikzylinder 12 und die Druckfedern 11 können aber natürlich auch in Achsrichtung 10 fluchtend angeordnet werden, wenn die räumlichen Verhältnisse dies erlauben.As can be seen in FIGS. 1 and 2, four compression springs 11 are arranged at an angular distance of 90 ° to one another in the exemplary embodiment shown. Furthermore, two hydraulic cylinders 12 are provided which lie opposite one another with respect to the axis 10. With regard to the compression springs 11, the hydraulic cylinders are arranged offset by 45 °. The hydraulic cylinders 12 and the compression springs 11 can of course also be arranged in alignment in the axial direction 10 if the spatial conditions allow this.
In Fig. 1 und in vergrößertem Maßstab in Fig. 3 ist auch noch zu sehen, dass in Verlängerung der Druckmittelzylinder 12 Führungen 15 vorgesehen sind, die ein Verdrehen der Druckringe 13 gegenüber demIn FIG. 1 and on an enlarged scale in FIG. 3 it can also be seen that in extension of the pressure medium cylinder 12 guides 15 are provided which prevent the pressure rings 13 from rotating
Träger 2 verhindern, was zu einem Ausknicken der Druckfedern 11 führen könnte.Prevent carrier 2, which could lead to buckling of the compression springs 11.
In Fig. 4 ist eine schematische Darstellung der erfindungsgemäßen Anordnung dargestellt, wobei in diesem Ausführungsbeispiel zwei Druckfedern 11 und zwei Druckmittelzylinder 12 vorgesehen sind. Diese stützen sich nach innen am stationären Träger 2 und nach außen an den Innen- ringen 5 Tragscheiben 4 des Walzenmantels 1 ab. Durch Verstellen der Druckmittelzylinder 12 wird dementsprechend der Walzenmantel 1 in Richtung des Doppelpfeiles 9 relativ zum stationären Träger 2 hin und herverschoben. 4 shows a schematic illustration of the arrangement according to the invention, two compression springs 11 and two pressure medium cylinders 12 being provided in this exemplary embodiment. These are supported on the inside on the stationary support 2 and on the outside on the inner rings 5 of the support disks 4 of the roll shell 1. By adjusting the pressure medium cylinders 12, the roller jacket 1 is accordingly pushed back and forth in the direction of the double arrow 9 relative to the stationary carrier 2.
