Description

Die Erfindung betrifft eine Vorrichtung zur Stabilisierung einer Papierbahn, insbesondere Tissuebahn, mit mindestens einem nach einem Trockenzylinder angeordneten (Bahn-)Stabilisator, wobei der Stabilisator direkt am Trockenzylinder unterhalb der Papierbahn angeordnet ist und wobei der Anstellwinkel des Stabilisators an den Trockenzylinder einstellbar ist und der Stabilisator an einem Schaberhalter oder Schaberbalken angeordnet ist.The invention relates to a device for stabilizing a paper web, in particular tissue web, with at least one arranged after a drying cylinder (web) stabilizer, wherein the stabilizer is disposed directly on the drying cylinder below the paper web and wherein the angle of the stabilizer is adjustable to the drying cylinder and the Stabilizer is arranged on a scraper holder or scraper bar.

Ein System zur Stabilisierung einer Papierbahn, speziell Tissuebahn ist aus der EP 1101863 bekannt. Hier sind nach einem Tissuezylinder mehrere Stabilisatoren angeordnet. Gleichzeitig erfolgt hier eine Staubabtrennung von der Oberseite der Papierbahn. Vor der Staubabsaugung ist ein Stabilisator für die Papier-/Tissue bahn vorgesehen, der zusätzlich mitgeschleppte Luft ableitet. Insbesondere bei der Produktion von hochwertigem Tissue (Soft-Tissue auf konventionellen Tissuemaschinen bzw. TAD Papiermaschinen) werden vorzugsweise angeschliffene Schaberklingen (Anschliff 5-40°) verwendet, sowie die Haftung zum Yankeezylinder relativ gering gehalten bzw. ist es überhaupt schwer möglich die Adhäsion der Papierbahn hoch einzustellen. Damit hat die Bahn die Tendenz nach unten zu gehen und wird nur durch den Papierzug der die Papierbahn gegen den oberen Stabilisator zieht, stabilisiert. Damit muss die Adhäsion zum Yankee und/oder niedriger Kreppgrad eingestellt werden was wiederum die Festigkeit bzw. die Dehnung des Papiers negativ beeinflusst.A system for stabilizing a paper web, especially tissue web is from the EP 1101863 known. Here, several stabilizers are arranged after a tissue cylinder. At the same time there is a dust separation from the top of the paper web. Before the dust extraction, a stabilizer for the paper / tissue web is provided, which additionally dissipates entrained air. In particular, in the production of high-quality tissue (soft tissue on conventional tissue machines or TAD paper machines) preferably ground scraper blades (bevel 5-40 °) are used, and the adhesion to Yankee cylinder kept relatively low or is it difficult at all the adhesion of the Set paper web high. Thus, the web has the tendency to go down and is only by the paper pullout that pulls the paper web against the upper stabilizer, stabilized. Thus, the adhesion to the Yankee and / or low Kreppgrad must be adjusted, which in turn adversely affects the strength or elongation of the paper.

Die EP 0 905 312 A2 offenbart eine Vorrichtung zur Bahnstabilisierung, die oberhalb der Bahn bzw. oberhalb der Schaberklinge angeordnet ist. Die US 6,328,852 B1 offenbart eine Bahnstabilisierungsvorrichtung, die direkt auf dem Schaberbalken befestigt ist. Der Schaberbalken selbst ist dabei drehbar gelagert. Die US 2002/0060036 A1 beschreibt eine Bahnführungseinrichtung, die die Bahn vom Trockenzylinder zum Aufwickler führt. Der Stabilisator ist dabei jedoch nicht am Schaberhalter oder am Schaberbalken angeordnetThe EP 0 905 312 A2 discloses a web stabilization device disposed above the web or above the doctor blade, respectively. The US 6,328,852 B1 discloses a web stabilizing device mounted directly on the doctor bar. The scraper itself is rotatably mounted. The US 2002/0060036 A1 describes a web guiding device which guides the web from the drying cylinder to the rewinder. However, the stabilizer is not arranged on the scraper holder or on the scraper bar

Ziel der Erfindung ist es daher die Bahnstabilität einer hochqualitativen Papierbahn, speziell Tissuebahn sofort nach Verlassen der Schaberklinge zu gewährleisten und damit die Möglichkeit zu schaffen, die Qualität des Papiers und/oder Produktionsgeschwindigkeit zu erhöhen.The aim of the invention is therefore to ensure the web stability of a high quality paper web, especially tissue web immediately after leaving the doctor blade and thus to create the opportunity to increase the quality of the paper and / or production speed.

Dies wird erfindungsgemäß dadurch erreicht, dass der Anstellwinkel des Stabilisators unabhängig vom Schaberanstellwinkel einstellbar ist.This is inventively achieved in that the angle of attack of the stabilizer is independent of the Schaberanstellwinkel adjustable.

Damit kann ein konstanter Abnahmewinkel der Papierbahn erreicht werden, der eine gute Bahnführung bewirkt, wobei ein allfälliges Flattern der Papierbahn verhindert wird.Thus, a constant acceptance angle of the paper web can be achieved, which causes a good web guide, with a possible fluttering of the paper web is prevented.

Außerdem kann die Kreppwirkung (der Kreppwinkel) unabhängig von einer optimalen Bahnführung durch den Stabilisator eingestellt werden.In addition, the creping effect (creping angle) can be adjusted independently of optimum web guiding by the stabilizer.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass der Stabilisator Öffnungen zur Luftausblasung bzw. Luftabsaugung aufweist. Durch die Luftausblasung bzw. Luftabsaugung wird die Bahn an die Oberfläche des Stabilisators gesaugt und somit die Stabilität der Bahnführung weiter verbessert.An advantageous development of the invention is characterized in that the stabilizer has openings for Luftausblasung or air extraction. By the air blowing or air suction, the web is sucked to the surface of the stabilizer and thus further improves the stability of the web guide.

Wird der Stabilisator schwenkbar, insbesondere abschwenkbar ausgeführt, so kann ein einwandfreier Abrissbetrieb und ein einfacheres Wiederaufführen der Papierbahn erreicht werden.If the stabilizer is designed to be pivotable, in particular swiveling out, perfect demolition operation and a simpler reintroduction of the paper web can be achieved.

Besonders gut lässt sich die Erfindung einsetzen, wenn der Trockenzylinder ein Yankeezylinder ist.The invention can be used particularly well when the drying cylinder is a Yankee cylinder.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass der Abstand des Stabilisators vom Trockenzylinder zwischen 0 und 500 mm, vorzugsweise zwischen 0 und 200 mm, beispielsweise etwa 50 mm beträgt.An advantageous development of the invention is characterized in that the distance of the stabilizer from the drying cylinder is between 0 and 500 mm, preferably between 0 and 200 mm, for example about 50 mm.

Die Erfindung wird nun anhand der Zeichnungen beispielhaft beschrieben, wobei Fig. 1 eine Variante der Erfindung und Fig. 2 eine weitere Variante der Erfindung darstellt.The invention will now be described by way of example with reference to the drawings, in which: Fig. 1 a variant of the invention and Fig. 2 represents a further variant of the invention.

Die Tissueerzeugung erfolgt zu einem hohen Prozentsatz mit der Endtrockenstufe auf einem Yankeezylinder 1. Von diesem Yankeezylinder 1 wird die getrocknete Papierbahn 2 durch eine Schaberklinge 4 abgenommen, die in einem Schaberhalter 6 geführt wird, der wiederum von einem Schaberbalken 5 gehalten wird. Vom Abnahmepunkt 9 vom Yankeezylinder 1 wird die Bahn 2 über Stabilisierungselemente 7, in gewissen Fällen über Glättwerk(e) zu einem (nicht dargestellten) Roller geführt, der die Bahn dort mit einer bestimmtem Geschwindigkeit auf eine Rolle aufwickelt. Die Papierqualität wird im Abnahmepunkt 9 maßgeblich beeinflusst. Um die Qualitätsparameter wie Festigkeit, Dehnung, Weichheit, Volumen optimal einstellen zu können ist es oft notwendig, die Adhäsion der Papierbahn am Yankeezylinder 1 niedrig zu halten. Auch die Abzugsgeschwindigkeit der Papierbahn in Richtung Glättwerk bzw. Roller wird meist sehr niedrig eingestellt. Ebenfalls wird der Krepp schaber 4 mit einem relativ hohen Anschliffwinkel β betrieben. Alle diese Einstellungen führen jedoch zu Schwierigkeiten in der Stabilität der Bahn und somit zu Laufschwierigkeiten der Maschine, zu Qualitätskompromissen und zu Geschwindigkeitslimitierungen.The tissue production takes place to a high percentage with the final drying stage on a Yankee cylinder 1. From this Yankee cylinder 1, the dried paper web 2 is removed by a doctor blade 4, which is guided in a scraper holder 6, which in turn is held by a scraper 5. From the take-off point 9 from the Yankee cylinder 1, the web 2 is guided via stabilizing elements 7, in certain cases via calender (e) to a roller (not shown), which winds the web there at a certain speed onto a roll. The paper quality is in Acceptance point 9 significantly influenced. In order to optimally adjust the quality parameters such as strength, elongation, softness and volume, it is often necessary to keep the adhesion of the paper web to the Yankee cylinder 1 low. The withdrawal speed of the paper web in the direction of calender or roller is usually set very low. Also, the crepe scraper 4 operated at a relatively high bevel angle β. All these settings, however, lead to difficulties in the stability of the web and thus to running difficulties of the machine, to quality compromises and speed limits.

Die Erfindung soll diese Nachteile reduzieren, indem die Papierbahn 2 gemäß Fig. 1 unmittelbar am Abnahmepunkt 9 vom Yankeezylinder 1 durch ein Stabilisierungselement 3, das an einem Schaberhalter 6 oder an einem Schaberbalken 5 befestigt ist, übernommen und geführt wird. Die Befestigung kann fix oder bevorzugt schwenkbar ausgeführt sein. Die Abschwenkposition des Stabilisators 3 ist strichliert dargestellt. In dieser Position kann die Papierbahn nach einem Abriss sehr leicht wieder aufgeführt werden. Der Stabilisator kann auch an der Stuhlung der Papiermaschine befestigt werden. Der Anstellwinkel α des Stabilisators ist dabei einstellbar und beträgt vorzugsweise 80 - 100 °. Der Anstellwinkel (Kreppwinkel) χ des Schabers 4 ist vom Anstellwinkel α des Stabilisators unabhängig einstellbar, wodurch einerseits die Kreppwirkung und andererseits die Bahnführung getrennt optimal einstellbar sind. Der Anstellwinkel (Kreppwinkel) χ des Schabers 4 beträgt üblicherweise ca. 10 - 35 °. Durch die Trennung der Anstellwinkel vom Schaber und vom Stabilisator wird auch erreicht, dass die Papierbahn nicht an der Schaberoberfläche entlang läuft und dort Probleme auftreten.The invention is intended to reduce these disadvantages by the paper web 2 according to Fig. 1 is taken over and guided directly at the pick-up point 9 from the Yankee cylinder 1 by a stabilizing element 3 which is attached to a scraper holder 6 or on a scraper bar 5. The attachment can be made fixed or preferably pivotable. The Abschwenkposition of the stabilizer 3 is shown by dashed lines. In this position, the paper web can be listed very easily after a demolition. The stabilizer can also be attached to the paper machine frame. The angle of attack α of the stabilizer is adjustable and is preferably 80-100 °. The angle of attack (creping angle) χ of the scraper 4 is independently adjustable from the angle of attack α of the stabilizer, whereby on the one hand the creping effect and on the other hand the web guide are optimally adjusted separately. The angle of attack (creping angle) χ of the scraper 4 is usually about 10 - 35 °. By separating the angle of attack of the scraper and the stabilizer is also achieved that the paper web does not run along the scraper surface and problems occur there.

Besonders vorteilhaft ist eine Ausführung gemäß Fig. 2, bei der das Stabilisierungselement 3 mindestens eine Öffnung 8 zur Druckluftausblasung aufweist oder mit einer Lufteinsaugungsöffnung 8, die mit einer Saugeinheit verbunden ist, von unten gestützt bzw. stabilisiert wird. Auch hier ist eine mögliche Abschwenkposition des Stabilisators 3 strichliert dargestellt. Um den optimalen Abnahmewinkel α und die optimale Abnahmestabilität zu gewährleisten, ist der Abstand x des Stabilisierungselementes 3 von der Oberfläche des Trockenzylinders 1 so gering wie möglich zu halten. Bevorzugt wird ein Abstand x von 0 bis 200 mm eingestellt, wobei er am günstigsten etwa 50 mm beträgt und in Ausnahmefällen bis zu 500 mm betragen kann.Particularly advantageous is an embodiment according to Fig. 2 in which the stabilizing element 3 has at least one opening 8 for the discharge of compressed air or is supported or stabilized from below with an air intake opening 8, which is connected to a suction unit. Again, a possible Abschwenkposition of the stabilizer 3 is shown by dashed lines. In order to ensure the optimum acceptance angle α and the optimal acceptance stability, the distance x of the stabilizing element 3 from the surface of the drying cylinder 1 is to be kept as low as possible. Preferably, a distance x is set from 0 to 200 mm, where it is most preferably about 50 mm and may be up to 500 mm in exceptional cases.
