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.The invention relates to a device for stabilizing a paper web, in particular Tissue web, with at least one after a drying cylinder arranged (rail) stabilizer, wherein the stabilizer directly on the drying cylinder is arranged below the paper web.

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 off EP 1101863. Here are several after a tissue cylinder Stabilizers arranged. At the same time a dust separation of the top of the paper web. Before the dust extraction is a stabilizer for provided the paper / tissue web, which additionally entrains entrained air. Especially in the production of high-quality tissue (soft tissue on conventional tissue machines or TAD paper machines) preferably used scraper blades (bevel 5-40 °) used, and the liability to Yankee cylinder kept relatively low or is it ever difficult to adjust the adhesion of the paper web high. Thus, the web has the tendency to go down and is only by the Paper train that pulls the paper web against the upper stabilizer stabilizes. This must set the adhesion to the Yankee and / or low creping which in turn become the strength or elongation of the paper negatively influenced.

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 the web stability of a high-quality paper web, especially tissue web immediately after leaving the scraper blade too ensure and thus the possibility of creating the quality of the paper and / or increase production speed.

Dies wird erfindungsgemäß dadurch erreicht, dass der Anstellwinkel des Stabilisators an den Trockenzylinder einstellbar ist. Damit kann ein konstanter Abnahmewinkel der Papierbahn erreicht werden, der eine gute Bahnführung bewirkt, wobei ein allfälliges Flattern der Papierbahn verhindert wird.This is inventively achieved in that the angle of the Stabilizer is adjustable to the drying cylinder. This can be a constant Acceptance angle of the paper web can be achieved, which is a good web guide causes, with any fluttering of the paper web is prevented.

Eine günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass der Anstellwinkel des Stabilisators unabhängig vom Schaberanstellwinkel einstellbar ist. Damit kann die Kreppwirkung (der Kreppwinkel) unabhängig von einer optimalen Bahnführung durch den Stabilisator eingestellt werden. A favorable embodiment of the invention is characterized in that the angle of attack of the stabilizer can be adjusted independently of the scraper setting angle is. Thus the creping effect (the creping angle) can be independent of an optimal web guide can be adjusted 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 that the stabilizer has openings for air blow-out or air extraction. By the Luftausblasung or air extraction, the web to the Surface of the stabilizer sucked and thus the stability of the web guide further improved.

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 swivelable, then can be a perfect demolition operation and a simpler re-run of the Paper web can be achieved.

Eine bevorzugte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass der Stabilisator am Schaberhalter oder Schaberbalken angeordnet ist.A preferred embodiment of the invention is characterized the stabilizer is arranged on the scraper holder or scraper bar.

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

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 that the distance of the stabilizer from the drying cylinder between 0 and 500 mm, preferably between 0 and 200 mm, for example about 50 mm is.

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, wherein Fig. 1 shows a variant of the invention and Fig. 2 shows a further variant of Invention represents.

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 Kreppschaber 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.Tissue production occurs to a high percentage with the final drying step on a Yankee cylinder 1. From this Yankee cylinder 1 is the dried Paper web 2 removed by a doctor blade 4, the in a scraper holder 6 is guided, in turn, by a scraper. 5 is held. From the pickup point 9 from Yankee 1, the web is the second via stabilizing elements 7, in certain cases via calender (e) to a (not shown) guided roller, which there the track with a certain Speed winding on a roll. The paper quality is in Acceptance point 9 significantly influenced. To the quality parameters like Strength, elongation, softness, to be able to optimally adjust the volume often necessary, the adhesion of the paper web on the Yankee cylinder 1 to low hold. Also, the withdrawal speed of the paper web in the direction of calender or scooter is usually set very low. Also becomes the creping scraper 4 operated with a relatively high angle β. All these settings however, lead to difficulties in the stability of the railway and thus to running difficulties of the machine, to quality compromises and to 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.The invention is intended to reduce these disadvantages by the paper web 2 according to Fig. 1 directly at the take-off point 9 from the Yankee cylinder 1 by a Stabilizing element 3, which on a scraper holder 6 or on a Scraper 5 is attached, taken over and guided. The attachment can be executed fixed or preferably pivotable. The swing-away position of the stabilizer 3 is shown by dashed lines. In this position, the Paper web can be listed very easily after a demolition. Of the Stabilizer can also be attached to the paper machine.

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 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 by the angle α of the stabilizer, whereby on the one hand the creping effect and on the other hand the web guide separated are optimally adjustable. The angle of attack (creping angle) χ of the scraper 4 is usually about 10 - 35 °. By separating the angle of attack from Scraper and stabilizer is also achieved that the paper web is not on the scraper surface runs along 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 at least one opening 8 for Druckluftblasblasung or with an air intake opening 8 connected to a suction unit is connected, supported from below or stabilized. Again, one possible Abschwenkposition of the stabilizer 3 shown by dashed lines. To the optimal acceptance angle α and the optimal acceptance stability ensure the distance x of the stabilizing element 3 of the Surface of the drying cylinder 1 to be kept as low as possible. Prefers a distance x is set from 0 to 200 mm, where it is best about 50 mm and may be up to 500 mm in exceptional cases.
