Definitions
- the present invention relates to a method and a device for removing dust, waste and short fibers in the departure zone of a card or card, which has a take-off roll or doffer, a customer an upper and a lower nip roll, and a transverse conveyor belt.
- Carding and carding are used to clean and open cotton or other fiber. These cleaning steps release a lot of dust, short fibers and other waste that accumulates in the card. When these partially flocked agglomerates of dust and short fibers are dragged back from the nonwoven or sliver, this causes an impurity or thick spot in the end product of the card or card. These are extremely undesirable effects and lead, for example, to an impairment of the downstream spinning process.
- a non-woven fabric is formed which is brought together by the transverse conveyor belt to form a sliver.
- the fibers are handed over several times from roller to roller whereby there are spaces through appropriate arrangements of the rollers, in which the pollution can accumulate with preference.
- the small air movements that arise in particular by the squeezing rollers in these spaces circular air movements, which also have an adverse effect on the removal of this pollution.
- this accumulation of particles is most often a problem.
- the degree of soiling in these rooms depends on the material to be processed, the production volume, the degree of contamination of the raw material and the cleaning efficiency of the preceding cleaning processes as well as general conditions such as temperature and relative humidity in the production plant.
- the dust and short fibers With high levels of water vapor in the air, the dust and short fibers will tend to develop sticky properties and accumulate in areas where there is no airflow. By contrast, with a relatively low water vapor content, the dust and the short fibers tend to remain isolated and accumulate in circular air currents.
- a solution according to the invention provides a compressed air device for generating a predetermined air flow in the area between the take-off roll, the take-off and the squeeze rolls.
- the compressed air device is arranged in the region between the take-off roll, the pick-up and the squeegee so that the air flow blows through the opening gap between the lower squeegee and take-off roll.
- the airflow should be guided so that it does not disturb or impair the normal course of the fleece removal.
- the invention differs from devices such as US 3,235,911 A in which an air flow is used to support the fleece removal.
- the duration of the generated air flow is adjustable.
- the compressed air device may then optionally generate a continuous stream of air or operate at intervals, for example at intervals of 1 to 60 minutes, advantageously 3 to 30 minutes, producing a burst of air for a duration of up to 60 seconds, advantageously up to 10 seconds. It would be advantageous if the interval sequence and / or intensity is set and / or controlled by the controller, for example with an adjustable and / or controllable solenoid valve.
- the compressed air device is advantageously integrated in a non-woven baffle or Vliesleit Kunststoff, if they are present. But this integration should take place without affecting or impairing the function of the nonwoven guide plate or the Vliesleitmaschine.
- the compressed air device can be made of any suitable material, advantageously from a hollow profile of chromium steel or aluminum, possibly anodized.
- the profile can optionally be provided with at least one slot or hole in the suitable area. Combinations of slit-shaped, oval or round openings are conceivable.
- the choice of shape and the number of holes depends on the working width of the entire compressed air profile and the number of feed positions for the compressed air supply in the profile.
- An example of a solution according to the invention is an arrangement in a line of several round holes in the case of an infeed at the head or foot of the compressed air device.
- the holes can also be arranged in a pattern or staggered.
- a Abfallleitblech attached, which transports the dirt particles outside the carding board, where they are disposed of during normal soil cleaning.
- the construction of the Abfallleitblechs can be made of any suitable material, advantageously made of chromium steel or aluminum, possibly anodized.
- a dirt-repellent treatment of the surface of the material, for example a sliding layer, can additionally improve the dirt removal.
- One solution would be the arrangement of a suction device below the gap. This suction device can be coupled to the already existing central suction device of the card. As a result, the dirt is fed to a filter system. For the space between the squeeze roller and the transverse conveyor belt, the solution to the removal of the accumulated material is rather the arrangement of one or more suction devices.
- the sliver outlet may be located in the middle or on the side; the partial suction device therefore also in the middle or on the side.
- the suction device for the space above the upper doctor blade and the transverse belt device is formed by a suction funnel, whereby the dust and fiber laden air is sucked.
- a suction funnel for the space adjacent to the lower scraper and the lower squeeze roller on the side of the cross-belt device.
- These funnels can be made of any material. Again, the inside of the funnel can also be treated dirt-repellent.
- suction devices can be coupled to the already existing central suction device of the card.
- FIG. 1 shows as an example a schematic representation of a card 1.
- a flake hopper 2 flakes of the card 1 are supplied. The flakes pass in the lower part of the flake filling shaft 2 to beaters 3, 3 'and 3 "of the card 1.
- the three bursers 3, 3' and 3" open the fiber flakes.
- the last briseur 3 "passes the roughly parallelized fibers of a carding drum 4.
- the carding drum 4 cooperates with covers 5 and further parallelizes the fibers, after the fibers have in part passed several revolutions on the carding drum 4, they are taken from a take-off roll 7 removed from the card drum 4, fed to the squeezing roller 8 and finally deposited as a card sliver 9 in a can 10 in a jug.
- FIG. 2 shows a detailed schematic representation of the acceptance area of a card.
- the fibers are taken from the take-off roll 7 by a taker 16 removed and passed with the help of a Vliesleitmaschine 13 between two squeezing rollers 8 through, so that a non-woven fabric is formed.
- This fibrous web is brought together by the transverse conveyor belt 17 and formed into a card sliver or sliver. Unwanted accumulations of dust, protection and short fibers takes place mainly in the space A, which is delimited by the take-off roller 7, the pickup 16 and partially by the two squeezing rollers 8.
- accumulations occur in the space of the gap between the nip roller 8 and the doctor blade 12, 14 on the one hand and the transverse belt device 17 on the other hand, especially in the region of the transverse belt edges B and C there is an increased risk that accumulate particles.
- an inventive compressed air device 13 can be used and for the cleaning of the rooms B and C suction devices 11 and 15 are provided.
- the material throughput and the short fiber and dirt content but also depending on the general conditions in the production plant, such as temperature and relative humidity, you need individual cleaning components or combinations of these.
- FIG. 3 shows an arrangement with partial suction devices 11 and 15 in the form of a funnel above and below the sliver outlet (view front 'working side, indicated in FIG. 1 with a star). In addition, the flow of the suction air is shown The sliver 19 is transported forward between the two conveyor belts 20, 20 '.

Description
Die vorliegende Erfindung betrifft ein Verfahren beziehungsweise eine Vorrichtung zum Entfernen von Staub, Abfall und Kurzfasern in der Abgangszone einer Karde oder Krempel, welche eine Abnahmewalze oder Doffer, einen Abnehmer eine obere und eine untere Quetschwalze, und ein quer verlaufendes Förderband aufweist.The present invention relates to a method and a device for removing dust, waste and short fibers in the departure zone of a card or card, which has a take-off roll or doffer, a customer an upper and a lower nip roll, and a transverse conveyor belt.
Karden und Krempel werden zum Reinigen und Öffnen von Baumwolle oder anderem Fasergut benutzt. Bei diesen Reinigungsschritten wird viel Staub, Kurzfasern und sonstiger Abfall freigesetzt, der sich in der Karde anhäuft. Wenn diese zum Teil zu Flocken angewachsenen Agglomerate von Staub und Kurzfasern wieder von dem Faservlies oder dem Faserband mitgeschleppt werden, verursacht das eine Verunreinigung oder eine Dickstelle im Endprodukt der Karde oder des Krempels. Dies sind äusserst unerwünschte Effekte und führen zum Beispiel zu einer Beeinträchtigung des nachgelagerten Spinnprozesses.Carding and carding are used to clean and open cotton or other fiber. These cleaning steps release a lot of dust, short fibers and other waste that accumulates in the card. When these partially flocked agglomerates of dust and short fibers are dragged back from the nonwoven or sliver, this causes an impurity or thick spot in the end product of the card or card. These are extremely undesirable effects and lead, for example, to an impairment of the downstream spinning process.
In den Abgangszone, definiert durch die Anordnung von einer Abnahmewalze oder Doffer, einem Abnehmer, eine obere und eine untere Quetschwalze und eventuell ein quer verlaufendes Förderband, wird ein Faservlies geformt das durch das quer verlaufendes Förderband zusammengeführt wird um ein Faserband zu bilden. In diesen Bereich werden die Fasern mehrmals von Walze zu Walze übergeben wobei durch entsprechende Anordnungen der Walzen Räumen vorhanden sind, in welchen sich die Verschmutzung mit Vorliebe ansammeln kann. Dazu kommt, verursacht durch die kleinen Luftbewegungen, dass vor allem durch die Quetschwalzen in diesen Räumen kreisförmige Luftbewegungen entstehen, die sich zusätzlich negativ auf die Entfernung dieser Verschmutzung auswirken.
In dem Raum zwischen der Abnahmewalze, dem Abnehmer und der Quetschwalze und dem Raum zwischen Quetschwalze und dem quer verlaufenden Förderband ist diese Anhäufung von Teilchen am häufigsten ein Problem.In the exit zone, defined by the arrangement of a take-off roll or doffer, a taker, upper and lower nip rolls and possibly a transverse conveyor belt, a non-woven fabric is formed which is brought together by the transverse conveyor belt to form a sliver. In this area, the fibers are handed over several times from roller to roller whereby there are spaces through appropriate arrangements of the rollers, in which the pollution can accumulate with preference. In addition, caused by the small air movements that arise in particular by the squeezing rollers in these spaces circular air movements, which also have an adverse effect on the removal of this pollution.
In the space between the take-off roll, the pick-up and the nip roll, and the space between the nip roll and the transverse conveyor, this accumulation of particles is most often a problem.
Der Grad der Verschmutzung in diesen Räumen ist abhängig von dem zu verarbeitenden Material, der Produktionsmenge, dem Verschmutzungsgrad des Rohmaterials und der Reinigungseffizienz der vorgeschalteten Reinigungsprozesse sowie auch von allgemeinen Konditionen wie Temperatur und relative Feuchtigkeit in der Produktionsanlage.The degree of soiling in these rooms depends on the material to be processed, the production volume, the degree of contamination of the raw material and the cleaning efficiency of the preceding cleaning processes as well as general conditions such as temperature and relative humidity in the production plant.
Bei einem hohen Wasserdampfgehalt in der Luft werden der Staub und die Kurzfasern eher klebrige Eigenschaften entwickeln und sich in Zonen ansammeln, wo keine Luftströmung vorhanden ist. Dagegen bleiben bei einem relativ tiefen Wasserdampfgehalt der Staub und die Kurzfasern eher vereinzelt und sammeln sich in kreisenden Luftströmungen an.With high levels of water vapor in the air, the dust and short fibers will tend to develop sticky properties and accumulate in areas where there is no airflow. By contrast, with a relatively low water vapor content, the dust and the short fibers tend to remain isolated and accumulate in circular air currents.
Bei einer Erhöhung der Produktion sinkt die Reinigungseffizienz der Karde, was zur Folge hat, dass während der Verarbeitung des Materials im Abnahmebereich der Karde auch mehr Staub und Kurzfasern freikommen. Dadurch wird der Verschmutzungsgrad in den Räumen grösser. Dies gilt in gleichem Mass auch für die Verwendung von Rohmaterial mit einem grösseren Anteil an Schmutz oder Kurzfasern.Increasing the production reduces the cleaning efficiency of the card, as a result of which more dust and short fibers are released during the processing of the material in the removal area of the card. This increases the degree of contamination in the rooms. This applies to the same extent to the use of raw material with a greater proportion of dirt or short fibers.
Eine regelmässige Entfernung und Reinigung an mehreren Stellen des Abgangs kann die Anhäufung von Staub und Kurzfasern verhindern oder reduzieren. Es ist daher Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung vorzuschlagen, mit dem bzw. der eine gezielte Reinigung der Zwischenräume im Abgang der Karde oder des Krempels ermöglicht wird, ohne dabei die Gleichmässigkeit des erzeugten Vlies oder des Kardenbandes zu beeinflussen.Regular removal and cleaning at several points in the outlet can prevent or reduce the accumulation of dust and short fibers. It is therefore an object of the invention to propose a method and a device with which or a targeted cleaning of the interstices in the departure of the card or the card is made possible without affecting the uniformity of the produced web or the card sliver.
Eine erfindungsgemässe Lösung sieht eine Druckluftvorrichtung, zur Erzeugung einer vorgegebenen Luftströmung im Bereich zwischen der Abnahmewalze, des Abnehmers und der Quetschwalzen vor.A solution according to the invention provides a compressed air device for generating a predetermined air flow in the area between the take-off roll, the take-off and the squeeze rolls.
Vorteilhafterweise ist die Druckluftvorrichtung im Bereich zwischen der Abnahmewalze, des Abnehmers und der Quetschwalze so angeordnet, dass der Luftstrom der Öffnungsspalt zwischen der untere Quetschwalze und Abnahmewalze durchbläst. Der Luftstrom sollte so geführt sein dass er der normale Verlauf der Vliesabnahme nicht stört oder beeinträchtigt. Hierbei unterscheidet sich die Erfindung von Vorrichtungen wie die von
Weiterhin ist es vorteilhaft, wenn, abhängig vom Verschmutzungsgrad, die Dauer des erzeugten Luftstroms einstellbar ist. Die Druckluftvorrichtung kann dann wahlweise einen kontinuierlichen Luftstrom erzeugen oder in Intervallen arbeiten, beispielsweise in Intervallen von 1 bis 60 Minuten, vorteilhafterweise 3 bis 30 Minuten, einen Luftstoss für ein Dauer bis 60 Sekunden, vorteilhafterweise bis 10 Sekunden erzeugen. Von Vorteil wäre es, wenn die Intervallsequenz und/oder Intensität von der Steuerung aus eingestellt und/oder gesteuert wird, beispielsweise mit einem einstellbarer und/oder steuerbaren Magnetventil.Furthermore, it is advantageous if, depending on the degree of contamination, the duration of the generated air flow is adjustable. The compressed air device may then optionally generate a continuous stream of air or operate at intervals, for example at intervals of 1 to 60 minutes, advantageously 3 to 30 minutes, producing a burst of air for a duration of up to 60 seconds, advantageously up to 10 seconds. It would be advantageous if the interval sequence and / or intensity is set and / or controlled by the controller, for example with an adjustable and / or controllable solenoid valve.
Jedes zusätzliche Bauteil birgt die Gefahr in sich, selbst eine Ansammlung von Teilchen zu verursachen. Eine Integration zweier Komponenten kann mögliche Anhangpunkte für Fasern vermindern. Deswegen wird die Druckluftvorrichtung vorteilhafterweise in ein Vliesleitblech oder eine Vliesleitbrücke integriert, falls diese vorhanden sind. Diese Integration soll aber erfolgen, ohne die Funktion des Vliesleitblechs oder der Vliesleitbrücke zu beeinflussen oder zu beeinträchtigen.Every additional component carries the risk of causing particles to accumulate. Integration of two components can reduce potential attachment points for fibers. Therefore, the compressed air device is advantageously integrated in a non-woven baffle or Vliesleitbrücke, if they are present. But this integration should take place without affecting or impairing the function of the nonwoven guide plate or the Vliesleitbrücke.
Die Druckluftvorrichtung kann aus jeglichem geeigneten Material hergestellt werden, vorteilhafterweise aus einem Hohlprofil aus Chromstahlblech oder Aluminium, eventuell eloxiert. Für die Erzeugung des erfindungsgemässen Luftstroms kann das Profil im geeigneten Bereich wahlweise mit mindestens einem Schlitz oder Loch versehen werden. Kombinationen von schlitzförmigen, ovalen oder runden Öffnungen sind denkbar. Die Wahl der Form und die Anzahl Löcher ist abhängig von der Arbeitsbreite des gesamten Druckluftprofils und die Anzahl der Einspeisungspositionen für die Drucklufteinspeisung im Profil. Ein Beispiel einer erfindungsgemässen Lösung ist eine Anordnung in einer Linie von mehreren runden Löchern bei einer Einspeisung am Kopf oder Fuss der Druckluftvorrichtung. Die Löcher können auch in einem Muster oder versetzt angeordnet werden.The compressed air device can be made of any suitable material, advantageously from a hollow profile of chromium steel or aluminum, possibly anodized. For the production of the air stream according to the invention, the profile can optionally be provided with at least one slot or hole in the suitable area. Combinations of slit-shaped, oval or round openings are conceivable. The choice of shape and the number of holes depends on the working width of the entire compressed air profile and the number of feed positions for the compressed air supply in the profile. An example of a solution according to the invention is an arrangement in a line of several round holes in the case of an infeed at the head or foot of the compressed air device. The holes can also be arranged in a pattern or staggered.
Vorteilhafterweise ist unterhalb des Spalts, wo der Schmutz ausgeblasen wird, ein Abfallleitblech angebracht, welches die Schmutzteilchen nach ausserhalb der Kardeverschalung transportiert, wo diese während der normalen Bodenreinigung entsorgt werden. Auch die Konstruktion des Abfallleitblechs kann aus jeglichem geeigneten Material gefertigt werden, vorteilhafterweise aus Chromstahlblech oder Aluminium, eventuell eloxiert. Ein schmutzabweisende Behandlung der Oberfläche des Materials, zum Beispiel eine Gleitschicht, kann die Schmutzentfernung zusätzlich noch verbessern.
Ein Lösung wäre die Anordnung einer Absaugvorrichtung unterhalb des Spalts. Diese Absaugvorrichtung kann an die schon vorhandene zentrale Absaugvorrichtung der Karde gekoppelt werden. Dadurch wird der Schmutz einem Filtersystem zugeführt.
Für dem Raum zwischen der Quetschwalze und dem quer verlaufenden Förderband ist die Lösung der Entfernung des angehäuften Materials eher die Anordnung ein oder mehrerer Absaugvorrichtungen.Advantageously, below the gap where the dirt is blown out, a Abfallleitblech attached, which transports the dirt particles outside the carding board, where they are disposed of during normal soil cleaning. The construction of the Abfallleitblechs can be made of any suitable material, advantageously made of chromium steel or aluminum, possibly anodized. A dirt-repellent treatment of the surface of the material, for example a sliding layer, can additionally improve the dirt removal.
One solution would be the arrangement of a suction device below the gap. This suction device can be coupled to the already existing central suction device of the card. As a result, the dirt is fed to a filter system.
For the space between the squeeze roller and the transverse conveyor belt, the solution to the removal of the accumulated material is rather the arrangement of one or more suction devices.
Für die Anordnung der Querbandvorrichtung gegenüber den Quetschwalzen kann eine entscheidende Rolle spielen, wieviel unerwünschtes Material sich ansammelt und ob man nur im Bereich des Faserbandauslaufes, wo sich am meisten Teilchen ansammeln, oder über die gesamte Arbeitsbreite der Karde eine Absaugvorrichtung benötigt. Dieses kann auch mitentscheidend sein, ob man oben und/ oder unten eine Absaugvorrichtung benötigt wird. Der Faserbandauslauf kann in der Mitte oder an der Seite angeordnet sein; die partielle Absaugvorrichtung deswegen auch in der Mitte oder an der Seite.For the arrangement of the cross-belt device relative to the nip rollers can play a crucial role, how much unwanted material accumulates and whether you need only in the area of the sliver outlet, where most particles accumulate, or over the entire working width of the card a suction device. This can also be crucial, if you above and / or below a suction device is needed. The sliver outlet may be located in the middle or on the side; the partial suction device therefore also in the middle or on the side.
Der Absaugungsvorrichtung für den Raum oberhalb des oberen Abstreifmessers und der Querbandvorrichtung wird durch einen Absaugtrichter geformt, wodurch die staub- und fasernbeladene Luft abgesaugt wird. Ein ähnliche Vorkehrung ist vorgesehen für dem Raum neben dem unteren Abstreifer und der unteren Quetschwalze an der Seite der Querbandvorrichtung. Diese Trichter können aus jeglichem Material hergestellt werden. Auch hier kann die Innenseite des Trichters zusätzlich schmutzabweisend behandelt werden.The suction device for the space above the upper doctor blade and the transverse belt device is formed by a suction funnel, whereby the dust and fiber laden air is sucked. A similar provision is made for the space adjacent to the lower scraper and the lower squeeze roller on the side of the cross-belt device. These funnels can be made of any material. Again, the inside of the funnel can also be treated dirt-repellent.
Oberhalb ist der Abgangsbereich mit einer schwenkbaren Haube abgedeckt; eine weitere Lösung wäre die Integration der oberen Absaugvorrichtung 11 in diese Haube.
Für die untere Absaugvorrichtung wäre eine weitere Lösung eine Integration unter der Querbandvorrichtung im schwenkbaren Teil, wobei dann die Absaugöffnung abhängig von der Gesamtkonstruktion eher seitlich angeordnet sein muss.Above the outlet area is covered with a hinged hood; Another solution would be the integration of the
For the lower suction device, a further solution would be an integration under the transverse belt device in the pivotable part, wherein then the suction opening must be arranged laterally depending on the overall construction.
Auch diese Absaugvorrichtungen können an die schon vorhandene zentrale Absaugvorrichtung der Karde gekoppelt werden.These suction devices can be coupled to the already existing central suction device of the card.
Die Absaugkraft in den oberen und unteren Absaugvorrichtungen ist abhängig von der gewählte Breite und der Schlitzöffnung. Bei einem sehr hohen Verschmutzungsgrad können mehrere separate Absaugvorrichtungen an einer Seite vorgesehen werden, vorteilhafterweise mit einer gradualen Absaugkraft, erhöht in Richtung des eigentlichen Faserbandauslaufes. Alternativ kann dies auch mit der Anpassung des Ansaugschlitzes erreicht werden und /oder mit einer Einteilung des Trichters in mehrere Kammern, beispielsweise ein Schlitz, der in Richtung Faserbandauslauf immer breiter wird.

Für die Reinigung des Raumes A kann eine erfindungsgemässe Druckluftvorrichtung 13 eingesetzt werden und für die Reinigung der Räume B und C sind Absaugungsvorrichtungen 11 und 15 vorgesehen. Abhängig von der Grösse der Arbeitsgeschwindigkeit, dem Materialdurchsatz und dem Kurzfaser- und Schmutzanteil, aber auch abhängig von den allgemeinen Konditionen in der Produktionsanlage, wie Temperatur und relative Feuchtigkeit, benötigt man einzelne Reinigungskomponenten oder Kombinationen dieser.For cleaning the room A, an inventive
Die oberen und unteren Absaugvorrichtungen können über die gesamte Arbeitsbreite der Karde angeordnet werden oder nur über ein Teil. Der Bereich um den Faserbandauslauf ist am meisten gefährdet, weil hier mitgeschleppte Fasern und Schmutz mit dem neu geformten Faserband zusammenkommen können.
