Description

Die Erfindung bezieht sich auf einen Kalander mit einer oberen und einer unteren Walze, die zwischen zwei Ständereinheiten angeordnet sind und zwischen denen eine Faserstoffbahn, insbesondere eine Papierbahn, hindurchführbar ist.The invention relates to a calender with an upper and a lower roller, which are arranged between two stator units and between which a fibrous web, in particular a paper web, can be passed.

Aus der US 3 598 039 ist eine Papiermaschine mit einer Siebpartie bekannt, die mit einer Einhausung ausgestattet ist. Die Einhausung umfasst eine vollständig entfernbare Haube, die mit Öffnungsmitteln ausgestattet ist, um die Haube, insbesondere auch sektionsweise, teleskopisch abzuziehen. Die Haube dient dazu, den besonders viel Feuchtigkeit produzierenden Teil der Siebpartie in der Nähe des Stoffauflaufs von dem hinteren Teil zu trennen.From the US Pat. No. 3,598,039 is a paper machine with a wire section known, which is equipped with an enclosure. The housing comprises a completely removable hood, which is equipped with opening means for telescopically withdrawing the hood, in particular also in sections. The hood serves to separate the particularly moisture-producing part of the wire section near the headbox from the rear part.

Aus der WO 96/34145 ist eine Haube für eine Sieb- und eine Pressenpartie bekannt, die Wände und eine Decke umfasst, welche zusammen eine geschlossene Haube bilden. In Verbindung mit der Haube ist auch eine Vorrichtung zur Einstellung einer Belüftung vorgesehen. Die Wände der Haube können aus Innen- und Außenwänden bestehen, so dass zwischen ihnen ein Luftstrom geführt werden kann.From the WO 96/34145 a hood for a wire and a press section is known, comprising walls and a ceiling, which together form a closed hood. In connection with the hood also a device for adjusting a ventilation is provided. The walls of the hood may consist of inner and outer walls, so that between them an air flow can be performed.

Außerdem sind im Stand der Technik Kalander zur Glättung einer Papierbahn bekannt, beispielsweise aus der EP 0 732 445 B1 . Der Kalander umfasst einen Walzenstapel, der zwischen jeweils einer harten und einer weichen Walze gebildete Arbeitsspalte und einen zwischen zwei weichen Walzen gebildeten Wechselspalt umfasst, um die Papierbahn in den Arbeitsspalten für eine bestimmte Verweildauer eine Druckspannung auszusetzen. Der Kalander dient dazu, gestrichene oder ungestrichene Papiere zu satinieren, beispielsweise Druckpapiere oder Silikon-Rohpapiere. Als "harte" Walzen werden Metallwalzen mit einer glatten oder harten Oberfläche bezeichnet, die im wesentlichen für die Glätte und den Glanz verantwortlich sind. Als "weiche" Walzen bezeichnet man Walzen mit einer elastischen oder weichen Oberfläche, die im wesentlichen für eine gleichmäßige Verdichtung sorgen. Der Wechselspalt ist erforderlich, damit beide Seiten der Papierbahn eine etwa gleichmäßige Behandlung erfahren.In addition, calenders are known in the art for smoothing a paper web, for example from the EP 0 732 445 B1 , The calender comprises a roll stack which comprises work gaps formed between a respective hard and a soft roll and an exchange gap formed between two soft rolls in order to expose the paper web in the working nips for a certain dwell time to a compressive stress. The calender is used to satin coated or uncoated papers, such as printing papers or silicone base papers. As "hard" rollers are referred to metal rollers with a smooth or hard surface, which are responsible for the smoothness and gloss substantially. As "soft" rollers called Rollers with an elastic or soft surface, which provide essentially for a uniform compaction. The interchangeable gap is required so that both sides of the paper web undergo an approximately uniform treatment.

Es ist die Aufgabe der Erfindung, an einem Kalander den Ausbau einer beheizbaren Walze zu erleichtern.It is the object of the invention to facilitate the removal of a heatable roller on a calender.

Erfindungsgemäß wird diese Aufgabe bei einem Kalander der eingangs genannten Art dadurch gelöst, dass der Kalander einen klappbaren Queranker umfasst.According to the invention this object is achieved in a calender of the type mentioned in that the calender comprises a hinged cross-armature.

Der klappbare Queranker, der vorzugsweise an einer Ständereinheit schwenkbar befestigt ist, lässt sich leicht von dem Kalander abheben, beispielsweise mittels eines Hydraulikmechanismus, so dass die unmittelbar unterhalb des Querankers angeordnete obere Walze des Kalanders zugänglich wird.The foldable transverse anchor, which is preferably pivotally mounted on a stand unit, can be easily lifted off the calender, for example by means of a hydraulic mechanism, so that the upper roller of the calender arranged immediately below the transverse anchor becomes accessible.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen.Advantageous developments of the invention will become apparent from the dependent claims, the description and the drawings.

Von Vorteil ist eine Ausführungsform der Erfindung, gemäß der der Queranker selber Heizungen, insbesondere Induktionsheizungen zur Erwärmung der oberen Walze aufweist.An advantage of an embodiment of the invention, according to which the transverse armature itself has heaters, in particular induction heaters for heating the upper roller.

In eine vorteilhaften Ausgestaltung des Kalanders ist vorgesehen, dass die Walzen auf beiden Stirnseiten in U-förmigen Ständereinheiten gelagert sind.In an advantageous embodiment of the calender is provided that the rollers are mounted on both end sides in U-shaped stanchion units.

Zusätzlich lässt sich in einer Ausführungsform der Erfindung mit Vorteil vorsehen, dass die Walzen über an der Innenseite der Ständereinheiten angebrachte waagrechte Riegel in den Ständereinheiten gelagert sind.In addition, in one embodiment of the invention can advantageously provide that the rollers are mounted on the inside of the stand units mounted horizontal bar in the stator units.

Hierbei erweist es sich als vorteilhaft, wenn beide Walzen oder ausschließlich die untere Walze mittels eines auf der Unterseite der unteren Walze angebrachten Hubzylinders anhebbar sind.It proves to be advantageous if both rolls or exclusively the lower roller can be raised by means of a mounted on the underside of the lower roller lifting cylinder.

Ebenso ist in vorteilhafter Weise vorgesehen, dass der Queranker, insbesondere gemeinsam mit einer den Kalander auf seiner Oberseite abdeckenden Haube mittels eines hydraulischen oder eines pneumatischen Zylinders verschwenkbar ist.Likewise, it is advantageously provided that the transverse anchor, in particular together with a cover covering the calender on its top hood by means of a hydraulic or a pneumatic cylinder is pivotable.

Zusätzlich lässt trägt der Kalander mit Vorteil eine schwenkbare Haube, die auf ihrer Unterseite Heizungen, insbesondere Induktionsheizungen, zur Erwärmung der oberen Walze aufweist.In addition, the calender advantageously carries a pivotable hood, which has heaters, in particular induction heaters, for heating the upper roller on its lower side.

Durch die Erfindung wird ein einfacher Verschlussmechanismus für den Queranker und die Haube oder den Deckel eines Kalanders geschaffen, der leicht mittels einer Gewindestange oder mittels anderer Befestigungsmittel an einer seitlichen Stütze oder einer Ständereinheit des Kalanders oder einem die Stützen miteinander verbindenden Riegel arretiert werden kann. Auf diese Weise kann der Riegel oder dessen oberer Teil gleichzeitig als Lagerverschluss der oberen der beiden Walzen dienen. Alle während des Betriebs des Kalanders erforderliche Einrichtungen, insbesondere Versorgungsleitungen lassen sich in Verbindung mit der Haube an dem Ständer und/oder einem zwei Ständer miteinander verbindenden Riegel befestigen.The invention provides a simple locking mechanism for the transverse anchor and the hood or cover of a calender which can be easily locked by means of a threaded rod or other fastening means to a lateral support or a stand unit of the calender or a latch interconnecting the supports. In this way, the bolt or its upper part can also serve as a bearing closure of the upper of the two rollers. All required during operation of the calender devices, in particular supply lines can be in connection with the hood to the stand and / or a stand connecting two bars together.

Die Haube dient zur Isolation des Kalanders gegen thermische Verluste, wie sie beispielsweise durch Konvektion hervorgerufen werden. An der Verbindung zwischen der Haube und dem Ständer, d. h. im Bereich des Gelenks, durch das die Haube gegenüber dem Ständer gelagert ist, lassen sich Versorgungsleitungen vorsehen, so dass sich diese Stelle zur Energieübertragung nutzen lässt.The hood is used to isolate the calender against thermal losses, such as those caused by convection. At the junction between the hood and the stand, d. H. In the region of the joint through which the hood is mounted relative to the stand, supply lines can be provided, so that this point can be used for energy transmission.

Infolge der Schwenkbewegung der Haube wird die obere Walze freigelegt, so dass sie sich leicht wechseln lässt, wenn zudem der obere Riegel entfernt wird, so dass das Lager zugänglich ist.As a result of the pivoting movement of the hood, the upper roller is exposed so that it can be easily changed, if also the upper latch is removed, so that the warehouse is accessible.

Auch die Wartung von Anbauteilen, wie der Heizungen oder anderer Aggregate, die auf der Unterseite der Haube befestigt sind und gemeinsam mit ihr verschwenkbar sind, ist gegenüber dem Stand der Technik verbessert.The maintenance of attachments, such as heaters or other aggregates, which are mounted on the underside of the hood and are pivotable together with it, is improved over the prior art.

Die Haube wird wie ein drehbar befestigter Hebel an der einen Stuhlungsseite angelenkt und an der anderen Stuhlungsseite mit einer Schnelllöseeinheit befestigt, so dass das Lagergehäuse, in dem die obere Walze gelagert ist, verspannt ist.The hood is articulated like a rotatably mounted lever on one side of the chair and attached to the other side of the chair with a quick release, so that the bearing housing in which the upper roller is mounted, is braced.

Vorzugsweise ist die Haube mittels einer verschwenkbaren Gewindestange gegenüber den Ständereinheiten arretierbar.Preferably, the hood can be locked by means of a pivotable threaded rod relative to the stator units.

Neben den Heizungen, insbesondere den Induktionsheizungen, lassen sich unter der Haube weitere Aggregate, insbesondere ein Dampfbefeuchter, anordnen.In addition to the heaters, in particular the induction heaters, further units, in particular a steam humidifier, can be arranged under the hood.

Insgesamt bestehen die Vorteile der Erfindung in einer kraftschlüssigen Lagerbefestigung mit gleichzeitiger Befestigungsmöglichkeit für verschiedene Anbauteile mit optimaler Energieversorgung über nur einen Drehpunkt. Durch die feste Anordnung dieser Aggregate unterhalb der Haube entfallen bei Schwenkbewegungen der Haube Justagearbeiten, da die Aggregate positionsgenau wieder in die Betriebsstellung zurückgeschwenkt werden, wenn die Haube abgeschwenkt wurde.Overall, the advantages of the invention in a non-positive bearing mounting with simultaneous mounting option for various attachments with optimum power supply over only one pivot point. Due to the fixed arrangement of these units below the hood accounts for pivotal movements of the hood adjustment work, as the units are accurately positioned back swung back into the operating position when the hood has been swung.

Nachstehend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnungen näher erläutert. Es zeigen:

Der Querriegel 13 und die Haube 17 werden um ein Lager 18 verschwenkt. Hierzu ist ein hydraulischer oder pneumatischer Zylinder 19 an dem Ständer 11 um ein Lager 20 verschwenkbar gelagert. Eine von dem Zylinder 19 betätigte Kolbenstange 21 greift an einem Lager 22 an dem Querriegel 13 an, um diesen zu verschwenken.Together with the crossbar 13 and the heaters 14, 15 and 16 can also cover this upwardly covering hood 17 in a position 17 'pivot. The cross bar 13 and the hood 17 are pivoted about a bearing 18. For this purpose, a hydraulic or pneumatic cylinder 19 is pivotally mounted on the stand 11 about a bearing 20. An actuated by the cylinder 19 piston rod 21 engages a bearing 22 on the crossbar 13 to pivot it.

Der Querriegel 13 weist an seinem vorderen, dem Ständer 9 zugewandten Ende einen Befestigungsblock 23 auf, mit dem er in der Betriebsposition auf dem Ständer 10 aufliegt. In dieser Position lässt sich der Querriegel 13 und mit ihm auch die Haube 17 mittels einer im oberen Bereich des Ständers 10 gelagerten verschwenkbaren Gewindestange 24 gegenüber dem Ständer 10 befestigen, wenn die Gewindestange 24 in eine senkrechte Position in eine entsprechende Ausnehmung in dem Befestigungsblock 23 hineingeschwenkt wird und anschließend festgeschraubt wird.The cross bar 13 has at its front, the stand 9 facing the end of a mounting block 23, with which it rests in the operating position on the stand 10.
