Definitions
- the invention relates to a device for forming an extended nip between a mating roll and a shoe roll for treating a web, in particular a paper, board, tissue web or other fibrous web.
- Such devices are used in particular in press sections and calenders use.
- a wet press for dewatering fibrous webs is known in which an extended press zone is employed to substantially increase dewatering compared to other press rolls.
- an extended press nip is formed due to a concave shape of the sliding surface of the sliding shoe through which the fiber web passes.
- the circumferential band is held in a substantially cylindrical shape by attached to its end faces annular discs.
- the shoe is attached to a shoe foot, which is connected via a pressure pad made of an elastic material, such as plastic or rubber, with a fixed yoke and against this guided by pins in the printing direction and across this is held positively.
- a pressure pad made of an elastic material, such as plastic or rubber
- the enclosed space of the pressure pad is fluid beaufschlagbar via lines, so that it is possible to vary the contact pressure of the shoe against the counter roll.
- the pressure pad is arranged so that the force exerted on the shoe from the pressure pad resulting force passes through the second half of the press nip formed in the running direction of the roll circumference. As a result, a slow pressure increase is effected, which then drops rapidly at the end of the press zone, which is advantageous for a dewatering process.
- the pressure pad can be divided axially into zones.
- the disadvantage is that the pressure pad is made of an elastic material, e.g. Plastic or rubber, is susceptible to wear. The cost advantages of pressure pads over more complex load cylinder systems are therefore often lost due to shorter maintenance intervals.
- the object of the invention is therefore to provide a device for forming an extended nip according to the preamble of claim 1, wherein the press shoe can be pressed via a fluidbeaufschlagbares pressure pad as Anpressü to the backing roll and the pressure pad works wear.
- an apparatus for forming an extended nip in which all frictional effects between a punch-like portion of the press shoe and the pressure pad on the one hand and the groove-like chamber and the Pressure pad on the other hand be avoided.
- the pressure pad can be deployed through the side guide of a rolling wall from a flat first profile to a higher second profile, whereby a lifting movement of the press shoe is performed.
- the lifting movement allows the shifting of the press shoe relative to the roll shell and the setting of a pressing pressure in the extended nip.
- the pressure pad is thus subject to significantly lower wear.
- the fluid loading of the pressure pad according to the invention is virtually a Aufblasfluidbeetzung, wherein the roll wall always forms a rolled fold, which is maintained in all operating conditions.
- the rolling behavior of the rolling wall makes it possible to guide a punch-like portion of the shoe which extends axially along a shoe length which is usually transverse to the machine direction (MD).
- the pressure pad is made of a flexible material, which also forms the roll wall with a roll fold.
- a further advantage is that the pressure pad is formed by a fluidbeaufschlagbaren flexible hose whose two cross-section superimposed material layers are so U-shaped inserted into the groove-like chamber, that the tube folds of the leg ends of the U-shaped inserted tube form the roll wall.
- the roll wall is then integrally formed with the pressure pad, which also creates a simple and quick to install pressure pad.
- a molded part can be provided with an end restrained rolling wall.
- a plurality of pressure pads along a shoe width can be provided in the machine direction, each associated with a stamp-like portion of the press shoe. The adjustment of the line load along the press zone length of the extended nip is then variable.
- the pressure pad can be axially divided into zones.
- the stamp-like portion of the press shoe with different footprints can dip into the pressure pad (s).
- An edge or edge relief of the press shoe is adjustable.
- load cylinder devices can additionally be provided for this purpose with which the line load profile along the press zone in the extended nip can be varied.
- Fig. 1a and Fig. 2a show the invention relates according to a first embodiment of an apparatus for forming an extended nip 1 between a backing roll 2 and a shoe roll 3 for treating a web.
- the web is in particular a paper, board, tissue web or other fibrous web.

- the press shoe 6 has at least one stamp-like portion 12 or a foot on the back, which dips into at least one einstülpbares pressure pad 10 for the execution of strokes.
- the pressure pad 10 is supported via a roll wall 13 forming pressure pad side wall at the groove-like chamber 11 from.
- the pressure pad 10 is for this purpose made of a flexible material.
- the roll wall 13 forms a rolled fold 14 between the punch-like portion 12 of the press shoe 6 and an inner side wall 15 of the groove-like chamber 11.

Description
Die Erfindung betrifft eine Vorrichtung zum Bilden eines Langspalts zwischen einer Gegenwalze und einer Schuhwalze zum Behandeln einer Warenbahn, insbesondere einer Papier-, Karton-, Tissuebahn oder sonstigen Faserstoffbahn.The invention relates to a device for forming an extended nip between a mating roll and a shoe roll for treating a web, in particular a paper, board, tissue web or other fibrous web.
Derartige Vorrichtungen finden insbesondere in Pressenpartien und Kalandern Verwendung.Such devices are used in particular in press sections and calenders use.
Aus
Der von dem Druckkissen eingeschlossene Raum ist über Leitungen fluidbeaufschlagbar, so dass es möglich ist, den Anpressdruck des Gleitschuhs an die Gegenwalze zu variieren. Das Druckkissen ist dabei so angeordnet, dass die auf den Gleitschuh vom Druckkissen ausgeübte resultierende Kraft durch die in Laufrichtung des Walzenumfangs zweite Hälfte des gebildeten Pressspalts geht. Hierdurch wird ein langsamer Druckanstieg bewirkt, der dann am Ende der Presszone schnell abfällt, was für einen Entwässerungsvorgang vorteilhaft ist. Um über die Walzenbreite unterschiedliche Anpressdrücke einstellen zu können, kann das Druckkissen axial in Zonen unterteilt sein. Nachteilig ist, dass das Druckkissen aus einem elastischen Material, z.B. Kunststoff oder Gummi, verschleißanfällig ist. Die Kostenvorteile von Druckkissen gegenüber aufwändigeren Belastungszylindersystemen gehen deshalb aufgrund kürzerer Wartungsintervalle vielfach wieder verloren.The enclosed space of the pressure pad is fluid beaufschlagbar via lines, so that it is possible to vary the contact pressure of the shoe against the counter roll. The pressure pad is arranged so that the force exerted on the shoe from the pressure pad resulting force passes through the second half of the press nip formed in the running direction of the roll circumference. As a result, a slow pressure increase is effected, which then drops rapidly at the end of the press zone, which is advantageous for a dewatering process. In order to be able to set different contact pressures over the roll width, the pressure pad can be divided axially into zones. The disadvantage is that the pressure pad is made of an elastic material, e.g. Plastic or rubber, is susceptible to wear. The cost advantages of pressure pads over more complex load cylinder systems are therefore often lost due to shorter maintenance intervals.
Aus
Aufgabe der Erfindung ist es daher, eine Vorrichtung zum Bilden eines Langspalts nach dem Oberbegriff des Anspruchs 1 zu schaffen, bei der der Pressschuh über ein fluidbeaufschlagbares Druckkissen als Anpresseinheit an die Gegenwalze drückbar ist und das Druckkissen dabei verschleißarm arbeitet.The object of the invention is therefore to provide a device for forming an extended nip according to the preamble of
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Hierdurch wird eine Vorrichtung zum Bilden eines Langspalts geschaffen, bei der sämtliche Reibungswirkungen zwischen einem stempelartigen Abschnitt des Pressschuhs und dem Druckkissen einerseits und der nutartigen Kammer und dem Druckkissen andererseits vermieden werden. Unter Vermeidung von Stick-Slip-Effekten kann das Druckkissen durch die Seitenführung einer Rollwand aus einem flachen ersten Profil bis zu einem höheren zweiten Profil entfaltet werden, wodurch eine Hubbewegung des Pressschuhs ausgeführt wird. Die Hubbewegung ermöglicht das Verschieben des Pressschuhs gegenüber dem Walzenmantel und die Einstellung eines Pressdrucks im Langspalt. Das Druckkissen unterliegt damit einem deutlich geringeren Verschleiß.In this way, an apparatus for forming an extended nip is provided in which all frictional effects between a punch-like portion of the press shoe and the pressure pad on the one hand and the groove-like chamber and the Pressure pad on the other hand be avoided. By avoiding stick-slip effects, the pressure pad can be deployed through the side guide of a rolling wall from a flat first profile to a higher second profile, whereby a lifting movement of the press shoe is performed. The lifting movement allows the shifting of the press shoe relative to the roll shell and the setting of a pressing pressure in the extended nip. The pressure pad is thus subject to significantly lower wear.
Die Fluidbeaufschlagung des Druckkissens ist erfindungsgemäß quasi eine Aufblasfluidbeaufschlagung, bei der die Rollwand immer eine Rollfalte bildet, die bei allen Betriebszuständen erhalten bleibt. Das Abrollverhalten der Rollwand ermöglicht es, einen stempelartigen Abschnitt des Schuhs zu führen, der sich axial entlang einer Schuhlänge erstreckt, die üblicherweise quer zur Maschinenrichtung (MD) verläuft.The fluid loading of the pressure pad according to the invention is virtually a Aufblasfluidbeaufschlagung, wherein the roll wall always forms a rolled fold, which is maintained in all operating conditions. The rolling behavior of the rolling wall makes it possible to guide a punch-like portion of the shoe which extends axially along a shoe length which is usually transverse to the machine direction (MD).
Gemäß bevorzugter Ausführungsbeispiele ist das Druckkissen aus einem flexiblen Material hergestellt, das auch die Rollwand mit einer Rollfalte ausbildet. Dabei taucht der stempelartige Abschnitt des Pressschuhs zwischen zwei axial sich erstreckenden Rollfalten in das Druckkissen unter Einstülpung desselben ein.According to preferred embodiments, the pressure pad is made of a flexible material, which also forms the roll wall with a roll fold. The stamp-like portion of the press shoe between two axially extending roll folds immersed in the pressure pad under the same.
Vorteilhaft ist ferner, dass das Druckkissen gebildet wird von einem fluidbeaufschlagbaren flexiblen Schlauch, dessen zwei im Querschnitt übereinander angeordnete Materiallagen derart U-förmig in die nutartige Kammer eingelegt sind, dass die Schlauchfalten der Schenkelenden des U-förmigen eingelegten Schlauchs die Rollwand bilden. Die Rollwand ist dann einstückig ausgebildet mit dem Druckkissen, wodurch zudem ein einfach und schnell montierbares Druckkissen geschaffen wird. Alternativ kann ein Formteil mit endseitig eingespannter Rollwand vorgesehen sein.A further advantage is that the pressure pad is formed by a fluidbeaufschlagbaren flexible hose whose two cross-section superimposed material layers are so U-shaped inserted into the groove-like chamber, that the tube folds of the leg ends of the U-shaped inserted tube form the roll wall. The roll wall is then integrally formed with the pressure pad, which also creates a simple and quick to install pressure pad. Alternatively, a molded part can be provided with an end restrained rolling wall.
Weiterhin können mehrere Druckkissen längs einer Schuhbreite in Maschinenrichtung vorgesehen sein, denen jeweils ein stempelartiger Abschnitt des Pressschuhs zugeordnet ist. Die Einstellung der Linienlast entlang der Presszonenlänge des Langspalts ist dann variierbar.Furthermore, a plurality of pressure pads along a shoe width can be provided in the machine direction, each associated with a stamp-like portion of the press shoe. The adjustment of the line load along the press zone length of the extended nip is then variable.
Um über die Schuhlänge, d.h. die Walzenbreite quer zur Maschinenrichtung, unterschiedliche Anpressdrücke einstellen zu können, kann das Druckkissen axial in Zonen unterteilt sein. Alternativ oder zusätzlich kann der stempelartige Abschnitt des Pressschuhs mit unterschiedlichen Aufstandsflächen in das oder die Druckkissen eintauchen. Eine Randbe- oder Randentlastung des Pressschuhs ist dadurch einstellbar. Darüber hinaus können dazu auch zusätzlich Belastungszylindereinrichtungen vorgesehen sein, mit denen der Linienlastverlauf entlang der Presszone im Langspalt variiert werden kann.Over the shoe length, i. the roll width transverse to the machine direction, to be able to set different contact pressures, the pressure pad can be axially divided into zones. Alternatively or additionally, the stamp-like portion of the press shoe with different footprints can dip into the pressure pad (s). An edge or edge relief of the press shoe is adjustable. In addition, load cylinder devices can additionally be provided for this purpose with which the line load profile along the press zone in the extended nip can be varied.
