Description

Die Erfindung betrifft Supportverbindungen zwischen zwei Walzen, wobei der Walzenmantel mindestens einer Walze rotierbar um einen feststehenden Träger angeordnet, mittels wenigstens eines Stützelementes darauf gelagert und zum Träger entlang einer Druckebene der Walze verschiebbar ist.The invention relates to support connections between two rollers, the roller jacket of at least one roller being arranged rotatably around a fixed support, mounted thereon by means of at least one support element and being displaceable relative to the support along a pressure plane of the roller.

Derartige Verbindungen sind bereits bekannt und werden bei Walzenanordnungen verwendet, die zur Herstellung und Verarbeitung von Materialbahnen dienen. Insbesondere bei Faserstoffbahnen werden die jeweils ein Ende des Trägers der Walze aufnehmenden Supportteile über daran angeschraubte U-förmige Klammern miteinander verbunden. Wegen der dabei auftretenden Flächenpressungen und Biegemomente müssen diese sowie die Supportteile entsprechend groß und damit auch schwergewichtet ausgeführt werden. Damit verbunden ist auch eine erhebliche Zeitdauer für das Lösen dieser Verbindungen.Such connections are already known and are used in roller arrangements which are used for the production and processing of material webs. In the case of fibrous webs in particular, the support parts receiving one end of the carrier of the roller are connected to one another via U-shaped clamps screwed thereon. Because of the surface pressures and bending moments that occur, these and the support parts must be designed to be correspondingly large and therefore heavy-weighted. This also involves a considerable amount of time for the loosening of these connections.

Der Erfindung liegt die Aufgabe zugrunde, eine Supportverbindung zu schaffen, die eine kompakte Bauweise sowie einen schnellen Wechsel von Walze, Filz, Tuch o.ä. gestattet.The invention has for its object to provide a support connection that a compact design and a quick change of roller, felt, cloth or the like. allowed.

Erfindungsgemäß wurde die Aufgabe durch die im Anspruch 1 beschriebene Vorrichtung gelöst, wobei die Unteransprüche besondere Ausführungsformen darstellen.According to the invention the object was achieved by the device described in claim 1, the subclaims representing special embodiments.

Wesentlich dabei ist, daß die jeweils ein Ende des Trägers aufnehmenden Supportteile über mindestens ein entlang der Druckebene verlaufendes, längliches Verbindungsteil, welches an beiden Enden Verdickungen aufweist und in entsprechenden Aussparungen der Supportteile herausziehbar untergebracht ist, formschlüssig verbunden sind. Eine sichere Supportverbindung zwischen zwei Walzen ergibt sich dann, wenn der Walzenmantel mindestens einer Walze zum feststehenden Träger entlang einer Druckebene der Walze verschiebbar ist.It is essential that the support parts receiving one end of the carrier are positively connected via at least one elongate connecting part running along the pressure plane, which has thickenings at both ends and is removably accommodated in corresponding recesses in the support parts. A secure support connection between two rollers is obtained when the roller shell at least one roller to the fixed support along one Printing plane of the roller is displaceable.

Die Verdickungen der Verbindungsteile können beispielsweise einen prismatischen, trapezförmigen oder auch halbkreisförmigen Querschnitt aufweisen. Vorteilhaft ist es, wenn die Verdickungen die Querschnittsform eines Halbkreises besitzen, dessen gerade Begrenzung vom Verbindungsteil weggerichtet ist. Dies führt zur konstruktiven Vereinfachung der Aussparung, die damit lediglich aus dem länglichen Abschnitt sowie einer sich daran anschließenden Bohrung besteht.The thickening of the connecting parts can for example have a prismatic, trapezoidal or semicircular cross section. It is advantageous if the thickenings have the cross-sectional shape of a semicircle, the straight boundary of which is directed away from the connecting part. This leads to a design simplification of the cutout, which therefore only consists of the elongated section and a bore connected to it.

Um die in der Hauptsache von Zugkräften beanspruchten Verbindungsteile in der Größe zu begrenzen, sollten sie sich von der Außenseite der Supportteile über mindestens 50 % der Supportteildicke zur Walze hin erstrecken. Des weiteren ist es günstig, zwischen den Supportteilen zwei oder mehr Verbindungsteile einzusetzen und diese symmetrisch zur Druckebene anzuordnen.In order to limit the size of the connecting parts, which are mainly subjected to tensile forces, they should extend from the outside of the support parts to at least 50% of the support part thickness towards the roller. Furthermore, it is favorable to use two or more connecting parts between the support parts and to arrange them symmetrically to the pressure plane.

Die eventuell auftretenden Querkräfte sollten durch eine entsprechende Formgebung der sich berührenden Verbindungsflachen der Supportteile aufgenommen werden. Möglich ist dies auch durch die Einbettung eines Zwischenstückes zwischen den zwei Supportteilen. Dies hätte den zusätzlichen Vorteil, daß bei Entfernung desselben der Wechsel des Walzenmantels, Siebes, Filzes o.ä. ermöglicht oder erleichtert wird.The transverse forces that may occur should be absorbed by appropriate shaping of the contacting connecting surfaces of the support parts. This is also possible by embedding an intermediate piece between the two support parts. This would have the additional advantage that when the same is removed, the change of the roll shell, sieve, felt or the like. is made possible or facilitated.

In Abhängigkeit von den Einsatzfällen besteht eine Variante darin, daß die Supportteile der unteren Walze jeweils auf einem ortsfesten, die Supportteile gleichzeitig führenden Ständer aufliegen. Das Lösen der Supportverbindungen erfolgt dabei einfach durch Entlastung der Stützelemente, die den Walzenmantel einer Walze in Richtung zur Gegenwalze drücken. Nach diesem Entspannen der formschlüssigen Verbindung können die Verbindungsteile problemlos entnommen werden und das Abheben der Supportteile über entsprechende Hubvorrichtungen erfolgen.Depending on the application, a variant consists in that the support parts of the lower roller each rest on a stationary stand which simultaneously guides the support parts. The support connections are loosened simply by relieving the load on the support elements that press the roll shell of a roll in the direction of the counter roll. After this relaxation of the positive connection, the connecting parts can be easily removed and the support parts can be lifted off using appropriate lifting devices.

Im anderen Fall werden die Supportteile der oberen Walze von jeweils einem ortsfesten Ständer getragen. Über die Verbindungsteile hängen an diesen die Supportteile der unteren Walze. Macht sich hierbei ein Lösen der Verbindungen erforderlich, so geschieht dies ebenfalls über eine Entlastung der Stützelemente, wobei allerdings danach die untere Walze in ihrer Position durch entsprechende äußere Hilfsvorrichtungen zur weiteren Entspannung der Verbindung etwas angehoben und fixiert werden muß. Diese Anordnung ist insbesondere dann von Vorteil, wenn die Zugriffsmöglichkeiten auf die untere Walze verbessert werden müssen.In the other case, the support parts of the upper roller are each carried by a stationary stand. The support parts of the lower roller. If a loosening of the connections is necessary, this also takes place by relieving the load on the support elements, but afterwards the position of the lower roller has to be raised and fixed somewhat by appropriate external auxiliary devices to further relax the connection. This arrangement is particularly advantageous when the access options to the lower roller have to be improved.

Bei der in Fig. 1 dargestellten Ausführung bilden zwei Walzen 1 und 2 einen Walzenspalt zur Bearbeitung einer Materialbahn 3, wobei der Walzenmantel 13 der oberen Walze 1 rotierbar um einen feststehenden Träger 14 angeordnet, mittels mehrerer Stützelemente 17 darauf gelagert und zum Träger 14 entlang der Druckebene der Walze 1 verschiebbar ist. Derartige Stützelemente 17 sind beispielsweise aus der CH-PS 541 088 bekannt. Häufig werden diese Walzenanordnungen zur Glättung von Papierbahnen verwendet.In the embodiment shown in Fig. 1, two rollers 1 and 2 form a nip for processing a material web 3, the roller jacket 13 of the upper roller 1 rotatably arranged around a fixed support 14, mounted thereon by means of several support elements 17 and to the support 14 along the Printing level of the roller 1 is displaceable. Such support elements 17 are known for example from CH-PS 541 088. These roller arrangements are often used to smooth paper webs.

Die jeweils ein Ende der Träger 14 und 16 aufnehmenden Supportteile 5 und 6 sind dabei über jeweils zwei entlang der Druckebene verlaufende, sich über die gesamte Supportteildicke erstreckende, längliche Verbindungsteile 7, welche an beiden Enden Verdickungen 8 aufweisen und in entsprechenden Aussparungen 9 der Supportteile 5 und 6 parallel zur Walzenachse herausziehbar untergebracht sind, formschlüssig verbunden. Die Supportteile 6 der unteren Walze 2 liegen jeweils auf einem ortsfesten, beide Supportteile 5 und 6 gleichzeitig seitlich führenden und damit quer zur Druckebene auftretende Kräfte aufnehmenden Ständer 12 auf.The support parts 5 and 6 each receiving one end of the supports 14 and 16 are in each case via two elongate connecting parts 7 which run along the pressure plane and extend over the entire thickness of the support part, which have thickenings 8 at both ends and in corresponding cutouts 9 in the support parts 5 and 6 are housed pull-out parallel to the roller axis, positively connected. The support parts 6 of the lower roller 2 each rest on a stationary stand 12, which supports both support parts 5 and 6 at the same time laterally and thus absorbs forces transversely to the pressure plane.

Bei der Montage werden folglich die Supportteile 5 und 6 der Walzen 1 und 2 in den Ständer 12 eingeführt. Nachdem die Verbindungsteile 7 in die Aussparungen 9 geschoben worden sind, erfolgt die Fixierung der Verbindung durch die Verschiebung des Walzenmantels 13 entlang der Druckebene zur Walze 2 hin mit Hilfe der Stützelemente 17. Gelöst werden die Verbindungen in umgekehrter Reihenfolge.During assembly, the support parts 5 and 6 of the rollers 1 and 2 are consequently inserted into the stand 12. After the connecting parts 7 have been pushed into the recesses 9, the connection is fixed by moving the roller shell 13 along the pressure plane toward the roller 2 with the aid of the support elements 17. The connections are released in the reverse order.

Um die Verbindungsteile 7 an der Außenseite der Supportteile 5 und 6 gegen Verschieben zu sichern, können bekannte Sicherungselemente vorgesehen sein. Des weiteren ist es auch möglich, die Supportverbindungen bei mehr als zwei übereinanderliegenden Walzen 1 und 2 zu verwenden, wobei allerdings mindestens ein Walzenmantel 13 der jeweils einen Walzenspalt bildenden Walzen 1 und 2 entlang der Druckebene in beschriebener Weise verschiebbar sein muß.In order to secure the connecting parts 7 on the outside of the support parts 5 and 6 against displacement, known securing elements can be provided. Furthermore, it is also possible to use the support connections in the case of more than two rolls 1 and 2 lying one above the other, although at least one roll jacket 13 of the rolls 1 and 2 forming a roll nip must be displaceable along the pressure plane in the manner described.

Fig. 2 stellt eine andere Ausführungsform dar, bei welcher zwei Walzen 1 und 2 einen Walzenspalt zur Bearbeitung einer Materialbahn 3 bilden und der Walzenmantel 15 der unteren Walze 2 rotierbar um einen feststehenden Träger 16 angeordnet, mittels mehrerer Stützelemente 17 darauf gelagert und zum Träger 16 entlang der Druckebene der Walze 2 verschiebbar ist. Solche Anordnungen werden beispielsweise bei der Entwässerung von Faserstoffbahnen eingesetzt und sind u.a. aus der DE-PS 31 26 492 bekannt. Zur Aufnahme der Flüssigkeit wird dabei ein Filz 4 gemeinsam mit der Faserstoffbahn 3 durch den Walzenspalt geführt.2 shows another embodiment in which two rolls 1 and 2 form a roll nip for processing a material web 3 and the roll jacket 15 of the lower roll 2 is arranged rotatably around a fixed support 16, mounted thereon by means of a plurality of support elements 17 and to the support 16 is displaceable along the pressure plane of the roller 2. Such arrangements are used, for example, in the dewatering of fibrous webs and are, among other things. known from DE-PS 31 26 492. In order to absorb the liquid, a felt 4 is passed through the nip together with the fibrous web 3.

Aufgrund des Verschleißes ergibt sich bei diesen Vorrichtungen die Notwendigkeit eines schnellen und einfachen Wechsels der Walze, des Walzenmantels oder des Filzbandes. Aus diesem Grund wird beispielsweise in der DE-PS 31 00 522 eine Vorrichtung vorgeschlagen, bei der zwischen einem Cantilever-Träger und dem Abstützbock für die Preßwalze ein entfernbares Zwischenstück vorgesehen ist und der Cantilever-Träger eine Transporteinrichtung für das Ein- und Ausbauen der Preßwalze aufweist. Dies erfordert allerdings viel Platz, was sich bei Umrüstungen negativ auswirkt.Because of the wear, these devices result in the need for a quick and easy change of the roller, the roller jacket or the felt belt. For this reason, a device is proposed, for example, in DE-PS 31 00 522, in which a removable intermediate piece is provided between a cantilever carrier and the support frame for the press roll and the cantilever carrier is a transport device for installing and removing the press roll having. However, this requires a lot of space, which has a negative impact on conversions.

Die Form und Anordnung der Verbindungsteile 7 entspricht dem ersten Ausführungsbeispiel, wobei allerdings die Verdickungen 8 der Verbindungsteile 7 etwa die Querschnittsform eines Halbkreises besitzen, dessen gerade Begrenzung vom Verbindungsteil 7 weggerichtet ist. Die symmetrisch zur Druckebene angeordneten Aussparungen 9 haben somit eine längliche Form, an die sich jeweils eine Bohrung zur Aufnahme der Verdickung 8 anschließt. Weiterhin werden die Supportteile 5 der oberen Walze 1 von jeweils einem ortsfesten Ständer 11 getragen. An den Supportteilen 5 hängen die über die Verbindungsteile 7 befestigten Supportteile 6 für die Walze 2. Zur Aufnahme u. U. auftretender Querkräfte befindet sich jeweils zwischen den unteren Supportteilen 5 und 6 und dem Ständer 11 ein Zwischenstück 22.The shape and arrangement of the connecting parts 7 corresponds to the first exemplary embodiment, although the thickenings 8 of the connecting parts 7 have approximately the cross-sectional shape of a semicircle, the straight boundary of which is directed away from the connecting part 7. The recesses 9 arranged symmetrically to the pressure plane thus have an elongated shape, each of which is followed by a bore for receiving the thickening 8. Furthermore, the support parts 5 of the upper roller 1 are each carried by a stationary stand 11. On the support parts 5, the support parts 6 for the roller 2 are attached via the connecting parts 7. U. occurring transverse forces there is an intermediate piece 22 between the lower support parts 5 and 6 and the stand 11.

Dadurch, daß die am jeweiligen Ende des Trägers 14 und 16 der entsprechenden Walze 1 bzw. 2 jeweils ein Ende des Trägers 14 bzw. 16 aufnehmenden Supportteile 5 bzw. 6 direkt sowie lösbar miteinander verbunden sind und somit die Anpreßkraft der Walzen 1 und 2 über die Supportverbindungen und nicht wie üblich über einen Ständer aufgenommen wird, ist es möglich, die gesamte Anordnung leichter und kompakter zu gestalten. Dies wiederum führt dazu, daß ein zusätzlicher zwischen den Supportteilen 6 und teilweise darüberhinaus parallel zu den Trägern 14 bzw. 16 der Walzen 1 und 2 verlaufender Träger als Cantilever-Träger 18 geringen Ausmaßes verwendbar ist, der an einem Ende aus der Walzenanordnung geführt und dort mit einem feststehenden Bauteil 19 verbunden ist. Die Ständer 11 sind dabei über den Cantilever-Träger 18 verbunden.Characterized in that at the respective end of the carrier 14 and 16 of the corresponding roller 1 or 2 respectively one end of the carrier 14 or 16 receiving support parts 5 and 6 are directly and releasably connected to one another and thus the contact pressure of the rollers 1 and 2 via the support connections and not via a stand as usual, it is possible to make the entire arrangement lighter and more compact. This in turn leads to the fact that an additional carrier running between the support parts 6 and partly further parallel to the carriers 14 and 16 of the rollers 1 and 2 can be used as a cantilever carrier 18 of small dimensions, which carrier is guided out of the roller arrangement at one end and there is connected to a fixed component 19. The stands 11 are connected via the cantilever carrier 18.

Um auch einen schnellen und einfachen Walzenwechsel zu ermöglichen, sollte der Cantilever-Träger 18 eine Transporteinrichtung 20 für den Ein- und Ausbau der unteren Walze 2 aufweisen.In order to enable a quick and easy roll change, the cantilever carrier 18 should have a transport device 20 for installing and removing the lower roll 2.

Das Herstellen der Verbindungen erfolgt so, daß die untere Walze 2 über ihren Träger 16 sowie daran angreifende Hilfsvorrichtungen in einer vorgegebenen Position gehalten wird und anschließend die Supportteile 5 der oberen Walze 1 auf den Ständer 11 gesetzt werden. Nach dem Einschieben der Verbindungsteile 7 in die Aussparungen 9 erfolgt das Spannen der Verbindungen über die Verschiebung des Walzenmantels 15 mittels der Stützelemente 17 entlang der Druckebene zur Walze 1 hin.The connections are made in such a way that the lower roller 2 is held in a predetermined position via its carrier 16 and auxiliary devices acting thereon and then the support parts 5 of the upper roller 1 are placed on the stand 11. After inserting the connecting parts 7 into the recesses 9, this is done Tensioning the connections over the displacement of the roll shell 15 by means of the support elements 17 along the pressure plane towards the roll 1.

Das Lösen der Verbindungen kann nach dem Entspannen der Verbindungen über die Stützelemente 17 sowie einem geringfügigen Anheben des Trägers 16 und damit der Supportteile 6 erfolgen.The connections can be released after the connections have been relaxed via the support elements 17 and the support 16 and thus the support parts 6 have been slightly raised.

Um die untere Walze 2 zu wechseln, werden die Supportverbindungen entfernt, wobei das Anheben des triebseitigen Endes der unteren Walze 2 über eine Zylinder-Kolbeneinheit 21 der auf dem Cantilever-Träger 18 fahrbaren Transporteinrichtung 20 erfolgt. Das Anheben des führerseitigen Endes der unteren Walze 2 sowie das Herausziehen wird über eine am führerseitigen Walzenende angreifende Hebevorrichtung realisiert. Dabei werden natürlich die seitlich zwischen den unteren Supportteilen 6 und dem Ständer 11 vorhandenen Zwischenstücke 22 entfernt.In order to change the lower roller 2, the support connections are removed, the drive-side end of the lower roller 2 being lifted via a cylinder / piston unit 21 of the transport device 20 which can be moved on the cantilever carrier 18. The lifting of the end of the lower roller 2 on the driver's side and the pulling out are carried out by means of a lifting device acting on the roller end on the driver's side. The intermediate pieces 22 present laterally between the lower support parts 6 and the stand 11 are of course removed.

Der Wechsel des unteren Walzenmantels 15 setzt ebenfalls das Lösen der führerseitigen Supportverbindungen sowie der seitlich zwischen dem Ständer 11 und dem unteren Supportteil 6 vorhandenen Zwischenstücke 22 voraus. Falls, wie in Fig. 2 gezeigt, das untere Supportteil 6 kleiner als der Walzenmantel 15 ist, erübrigt sich eine Entfernung desselben. Der Wechsel des Walzenmantels 15 kann nun über die bekannten Vorrichtungen erfolgen, wobei das führerseitige Ende des Trägers 16 der unteren Walze 2 in seiner Lage gehalten werden muß.The change of the lower roll shell 15 also requires the loosening of the support connections on the driver's side and the intermediate pieces 22 that are present laterally between the stand 11 and the lower support part 6. If, as shown in FIG. 2, the lower support part 6 is smaller than the roller jacket 15, there is no need to remove it. The roll shell 15 can now be changed using the known devices, the end of the carrier 16 of the lower roll 2 on the driver's side having to be held in position.

Beim Filzbandwechsel ist es wegen dem mit den Ständern 11 verbundenen Cantilever-Trägern 18 möglich, das Filzband 4 komplett einzuziehen. Dazu ist es notwendig, den Ständer 11 führerseitig etwas anzuheben, die Zwischenstücke 22 zwischen der Standfläche 23 und dem Ständer 11 zu entfernen und nach dem Lösen der Supportverbindungen das obere führerseitige Supportteil 5 anzuheben sowie die zwischen dem oberen Supportteil 5 und dem Ständer 11 vorhandenen Zwischenstücke 22 zu entfernen.When changing the felt belt, it is possible because of the cantilever supports 18 connected to the stands 11 to completely pull in the felt belt 4. For this purpose, it is necessary to lift the stand 11 slightly on the driver's side, to remove the intermediate pieces 22 between the standing surface 23 and the stand 11 and to lift the upper driver-side support part 5 and the intermediate pieces between the upper support part 5 and the stand 11 after loosening the support connections 22 to remove.

Das für das Herstellen und Lösen der Verbindungen notwendige Halten bzw. Anheben des Trägers 16 der unteren Walze 2 kann natürlich auch über Hilfsvorrichtungen erfolgen, die an den Supportteilen 6 der unteren Walze 2 angreifen.The holding or lifting of the carrier 16 of the lower roller 2, which is necessary for making and releasing the connections, can of course also take place via auxiliary devices which act on the support parts 6 of the lower roller 2.
