- Such a machine is made EP 1148172 A known.
- the fibrous web is supported on the opposite side when cutting with a jet of water. This support takes place at the US-A1 2001/0004007 through a sieve or even through a cutting table. During operation, soiling of the supporting surfaces by the fibers or the additives of the fibrous web occurs. In addition, the high pressure of the water jet over time also leads to the wear of the surfaces hit by the water jet.
- ansgesitzunge cutting table therefore often has an opening for the removal and suction of impurities and water.
- the separated strip is supported by vacuum sucked into a discharge funnel. This is very expensive, in particular with regard to the cleanliness of the cutting table and the removal of the strip.
- the object of the invention is therefore to simplify the structure of the cutting device with at least constant reliability.
- the elaborate cutting table can thus be reduced to a support plate.
- the support plate is very simple and ensures during cutting sufficient support of the fibrous web in the cutting area, the support plate has a recess for the water jet, so that it can pass unhindered.
- the cut edge strip falls down after the cutting area of the support plate.
- the run of the severed strip should be influenced by a guide device preferably in the form of a guide plate and / or a guide part of the support plate and / or a compressed air and / or a water jet nozzle.
- the support plate In order to prevent damage to the fibrous web and to counteract the accumulation of dirt, the support plate should form a flat as possible sliding surface, which runs approximately parallel to the fibrous web.
- the fibrous web should, at least in the unloaded state, run along the support plate through the water jet at a distance. Because of the flat and preferably smooth sliding surface a sliding of the fibrous web during cutting remains without negative effect. It has proven to be advantageous if the distance between the fibrous web and the sliding surface of the support plate, in particular in the unloaded state in the range of 0 to 2 mm, preferably between 0 and 0.5 mm.
- the rejects and parts of the fibrous web are collected and fed to pulp processing for recycling. Since the guide device supports the feeding of the severed strip into the pulper, expensive suction devices for guiding the separated edge strip can be saved.

Abstract
Description
Die Erfindung betrifft eine Maschine zur Herstellung und/oder Veredlung der Faserstoffbahn mit zumindest einer Düse, deren Wasserstrahl auf die Faserstoffbahn gerichtet ist, gemäß dem Oberbegriff vom Anspruch 1. Eine derartige Maschine ist aus
Wegen des hohen Drucks des Wasserstrahls und der Gewährleistung eines sauberen Schnittes unter Vermeidung von Ein- oder gar Abrissen wird die Faserstoffbahn beim Schneiden mit Wasserstrahl auf der gegenüberliegenden Seite abgestützt. Diese Abstützung erfolgt bei der
Gegenüber dem Wasserstrahl besitzt der ebenfalls ansgesprechene Schneidtisch daher oft eine Öffnung zum Abführen und Absaugen der Verunreinigungen und des Wassers. Der abgetrennte Streifen wird dabei unterstützt durch Vakuum in einen Abführtrichter gesaugt. Dies ist insbesondere hinsichtlich der Sauberhaltung des Schneidtisches und der Abführung des Streifens sehr aufwendig.Compared to the jet of water also ansgesitzunge cutting table therefore often has an opening for the removal and suction of impurities and water. The separated strip is supported by vacuum sucked into a discharge funnel. This is very expensive, in particular with regard to the cleanliness of the cutting table and the removal of the strip.
Die Aufgabe der Erfindung ist es daher den Aufbau der Schneideinrichtung bei zumindest gleichbleibender Betriebssicherheit zu vereinfachen.The object of the invention is therefore to simplify the structure of the cutting device with at least constant reliability.
Die Aufgabe dadurch wird durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.
Der aufwendige Schneidtisch kann damit auf ein Stützblech reduziert werden. Das Stützblech ist sehr einfach aufgebaut und gewährleistet während des Schneidens eine ausreichende Abstützung der Faserstoffbahn im Schneidbereich, wobei das Stützblech eine Aussparung für den Wasserstrahl besitzt, so dass dieser ungehindert hindurchtreten kann.The elaborate cutting table can thus be reduced to a support plate. The support plate is very simple and ensures during cutting sufficient support of the fibrous web in the cutting area, the support plate has a recess for the water jet, so that it can pass unhindered.
Der abgeschnittene Randstreifen fällt nach dem Schneidbereich vom Stützblech herunter. Nach dem Stützblech sollte der Lauf des abgetrennten Streifens von einer Führungseinrichtung vorzugsweise in Form eines Führungsbleches und/oder eines Führungsteiles des Stützblechs und/oder einer Druckluft- und/oder einer Wasserstrahl-Düse beeinflusst werden.The cut edge strip falls down after the cutting area of the support plate. After the support plate, the run of the severed strip should be influenced by a guide device preferably in the form of a guide plate and / or a guide part of the support plate and / or a compressed air and / or a water jet nozzle.
Um Beschädigungen der Faserstoffbahn zu verhindern und der Anlagerung von Verschmutzungen entgegen zu wirken, sollte das Stützblech eine möglichst ebene Gleitfläche bilden, die etwa parallel zur Faserstoffbahn verläuft.In order to prevent damage to the fibrous web and to counteract the accumulation of dirt, the support plate should form a flat as possible sliding surface, which runs approximately parallel to the fibrous web.
Für eine einwandfreie Schnittqualität und eine stabilen Schneidvorgang sollte die Faserstoffbahn zumindest im unbelasteten Zustand durch den Wasserstrahl mit einem Abstand an dem Stützblech entlang laufen. Wegen der ebenen und vorzugsweise glatten Gleitfläche bleibt ein Gleiten der Faserstoffbahn während des Schneidens ohne negative Wirkung. Dabei hat es sich als vorteilhaft erwiesen, wenn der Abstand zwischen Faserstoffbahn und der Gleitfläche des Stützblechs insbesondere im unbelasteten Zustand im Bereich von 0 bis 2 mm, vorzugsweise zwischen 0 und 0,5 mm liegt.For a perfect cut quality and a stable cutting process, the fibrous web should, at least in the unloaded state, run along the support plate through the water jet at a distance. Because of the flat and preferably smooth sliding surface a sliding of the fibrous web during cutting remains without negative effect. It has proven to be advantageous if the distance between the fibrous web and the sliding surface of the support plate, in particular in the unloaded state in the range of 0 to 2 mm, preferably between 0 and 0.5 mm.
Im Pulper werden der Ausschuss und Teile der Faserstoffbahn gesammelt und der Faserstoffaufbereitung zur Wiederverwertung zugeführt. Da die Führungseinrichtung die Zuführung des abgetrennten Streifens in den Pulper unterstützt, können aufwendige Saugeinrichtungen zur Führung des abgetrennten Randstreifens eingespart werden.In the pulper, the rejects and parts of the fibrous web are collected and fed to pulp processing for recycling. Since the guide device supports the feeding of the severed strip into the pulper, expensive suction devices for guiding the separated edge strip can be saved.
Zur Anpassung an bestimmte Betriebsbedingungen sollten die Düse und/oder das Stützblech und/oder die Führungseinrichtung bezüglich ihrer Lage einstellbar gestaltet sein.To adapt to certain operating conditions, the nozzle and / or the support plate and / or the guide device should be made adjustable with respect to their position.
Wegen der bereits erhöhten Festigkeit kann die Wasserstrahl-Schneideinrichtung im freien Zug der Faserstoffbahn, im Bereich der Trockenpartie angeordnet werden. Im freien Zug läuft die Faserstoffbahn ohne sich auf einem Band, einer Walze oder ähnlichem abzustützen.Because of the already increased strength, the water jet cutting device can be arranged in the free train of the fibrous web, in the area of the dryer section. In the open train, the fibrous web runs without being supported on a belt, a roller or the like.
Besonders einfach lässt sich die Einbauposition aufgrund der Pulperposition am Ende einer Trockengruppe, vorzugsweise nach dem letzten Trockenzylinder der Trockengruppe realisieren, weshalb die Wasserstrahl-Schneideinrichtung auch dort eingesetzt werden sollte. Nach dem Wegführen des Trockensiebes der Trockengruppe kann so die Wasserstrahl-Schneideinrichtung mit Vorteil zwischen einem, insbesondere dem letzten Trockenzylinder der Trockengruppe und einer folgenden Leitwalze angeordnet sein.The installation position can be realized particularly simply on account of the pulper position at the end of a drying group, preferably after the last drying cylinder of the drying group, which is why the water jet cutting device should also be used there. After the drying wire of the drying group has been removed, the water-jet cutting device can advantageously be arranged between one, in particular the last drying cylinder of the drying group and a following guide roll.

- Figur 2:
- eine Draufsicht des Stützbleches 3.

Die Faserstoffbahn 1 läuft in einer Trockenpartie einer Papiermaschine zur Trocknung derselben meist abwechselnd über beheizte Trockenzylinder 4 und besaugte Leitwalzen 11. Dabei wird die Faserstoffbahn 1 von zumindest einem Trockensieb 8 der jeweiligen Trockengruppe geführt, wobei die Faserstoffbahn 1 mit den Trockenzylindern 4 in Kontakt kommt.The fibrous web 1 runs in a dryer section of a paper machine for drying the same usually alternately over heated drying cylinders 4 and evacuated guide rollers 11. The fibrous web 1 is guided by at least one dryer 8 of the respective drying group, wherein the fibrous web 1 comes into contact with the drying cylinders 4.
Während der Trocknung nimmt der Feuchtegehalt der Faserstoffbahn 1 ab und die Festigkeit zu. Zur Herstellung sauberer Ränder der Faserstoffbahn 1, kommt die Wasserstrahl-Schneideinrichtung zum Einsatz. Wegen der erhöhten Festigkeit der Faserstoffbahn 1 kann dies im freien Zug der Faserstoffbahn 1 erfolgen.During drying, the moisture content of the fibrous web 1 decreases and the strength increases. To produce clean edges of the fibrous web 1, comes Water jet cutting device used. Because of the increased strength of the fibrous web 1, this can be done in the free train of the fibrous web 1.
Dies ist relativ einfach am Ende einer und insbesondere wie in der Figur 1 gezeigt der letzten Trockengruppe möglich. Nach dem Wegführen des entsprechenden Trockensiebes 8 kommt die Faserstoffbahn 1 in den Bereich der Wasserstrahl-Schneideinrichtung, wobei diese zwischen dem Trockenzylinder 4 und einer folgenden Leitwalze 5 angeordnet ist. Diese Wasserstrahl-Schneideeinrichtung besteht im wesentlichen aus einer Düse 2, die über der Faserstoffbahn 1 angeordnet ist und den Wasserstrahl etwa senkrecht auf die Faserstoffbahn 1 richtet. Zur Abstützung der Faserstoffbahn 1 befindet sich auf der gegenüberliegenden Seite ein Stützblech 3. Dieses Stützblech 3 hat eine ebene und glatte Oberfläche und ist im unbelasteten Zustand etwa 0,5 mm von der Faserstoffbahn 1 entfernt. Während des Schneidens wird die Faserstoffbahn 1 jedoch an das Stützblech 3 gedrückt. Um ein Abspritzen zu verhindern, besitzt das Stützblech 3 gemäß Figur 2 eine Aussparung 12 für den Wasserstrahl. Das Stützblech 3 umfasst außerdem noch ein Führungsteil 10, welches die Weiterleitung des abgetrennten Randstreifens in den Pulper 6 der Trockenpartie unterstützt.This is relatively easy at the end of one and in particular as shown in Figure 1 of the last drying group possible. After the removal of the corresponding drying wire 8, the fibrous web 1 comes into the region of the water jet cutting device, this being arranged between the drying cylinder 4 and a following guide roll 5. This water jet cutting device consists essentially of a nozzle 2, which is arranged above the fibrous web 1 and the water jet is directed approximately perpendicular to the fibrous web 1. To support the fibrous web 1 is located on the opposite side of a support plate 3. This support plate 3 has a flat and smooth surface and is about 0.5 mm away from the fibrous web 1 in the unloaded state. During cutting, however, the fibrous web 1 is pressed against the support plate 3. In order to prevent clogging, the support plate 3 according to Figure 2 has a
Da sich das Stützblech 3 parallel zum Lauf der Faserstoffbahn 1 erstreckt bietet es keine Möglichkeit zur Anlagerung von Fasern und anderen Verschmutzungen.Since the support plate 3 extends parallel to the run of the fibrous web 1, it offers no possibility for attachment of fibers and other contaminants.
Nach dem Stützblech 3 wird der abgetrennte Streifen 7 in den unter der Wasserstrahl-Schneideinrichtung angeordneten Pulper 6 der Trockenpartie geführt. Die aufgefangenen Faserstoffbahnreste können so einer Wiederverwertung zugeführt werden.After the support plate 3, the separated strip 7 is guided into the arranged below the water jet cutter pulper 6 of the dryer section. The collected pulp web remnants can thus be recycled.
Um den Streifen 7 nach dem Stützblech 3 zu führen sind hier Führungseinrichtungen vorgesehen. Nach dem Stützblech 3 bläst eine Druckluft- oder Wasserdüse 9 den Streifen 7 in Richtung Pulper 6. Am Trockenzylinder 4 anhaftenden Faserstoffbahnreste werden außerdem von einem Schaber 13 vom Trockenzylinder 4 entfernt.In order to guide the strip 7 to the support plate 3 guide means are provided here. After the support plate 3 a compressed air or water nozzle 9 blows the strip 7 in the direction of pulper 6 on the drying cylinder 4 adhering fibrous web residues are also from a scraper 13 from the drying cylinder 4th away.
Nach der Wasserstrahl-Schneideinrichtung gelangt die Faserstoffbahn 1 in einen anderen Bereich der Papiermaschine beispielsweise zum Streichen oder Glätten der Faserstoffbahn 1.After the water jet cutting device, the fibrous web 1 passes into another area of the paper machine, for example, for brushing or smoothing the fibrous web. 1
Die Wasserstrahl-Schneideinrichtung ist sehr einfach aufgebaut und spart wegen der ohne eine Saugvorrichtung auskommenden Randstreifenabführung unter Berücksichtigung des Dauerbetriebs sehr viel Energie.The water jet cutting device is very simple and saves a lot of energy because of the running without a suction edge trim removal taking into account the continuous operation.
