Abstract

A dust removal installation comprises an elctrostatically charged band (16), which collects dusts as it moves continuously around the area. The dust is removed from the band by first discharging (23) it and then passing it under suction hoods (26, 27). IT is then charged again (21) and recirculated. The band runs over non-conducting guide rollers (17), one of which is driven (20). The roller (17b) near the charging electrode is conducting and can act as charging element. Several bands running in different planes in a circular path can be used near the yarn feeders of a circular knitting machine. On a flat bed knitting machine the band takes a longitudinal instead of a circular path.

Description

Die Erfindung betrifft eine mit wenigstens einer Entstaubungsvorrichtung ausgerüstete Textilmaschine, insbesondere eine Strickmaschine.The invention relates to one equipped with at least one dedusting device Textile machine, in particular a knitting machine.

Unter dem Begriff "Entstaubung" werden in der Textilmaschinentechnik und im Rahmen der vorliegenden Erfindung Maßnahmen verstanden, die dem Zweck dienen, bei der Textilherstellung oder Textilverarbeitung entstehende und in der Luft dispergierte, z. B. durch Faserflug verursachte Stäube zu sammeln und/oder zu entfernen, um schädliche Staub-Zusammenballungen an empfindlichen Funktionsteilen der Textilmaschine zu vermeiden. Der Begriff "Staub" umfaßt dabei nicht nur Stäube in Form von Faser- und Flaumpartikeln bzw. Flusen, sondern grundsätzlich alle Partikel, die in der Textiltechnik anfallen und in die umgebende Atmosphäre gelangen.Under the term "dedusting" are used in textile machine technology and Understand the scope of the present invention measures that serve the purpose arising in textile production or textile processing and dispersed in the air, z. B. collecting and / or removing dusts caused by fiber flying, to harmful dust aggregations on sensitive functional parts of the To avoid textile machine. The term "dust" does not only include dusts in Form of fiber and fluff particles or fluff, but basically all particles, that occur in textile technology and reach the surrounding atmosphere.

Permanente Quellen von Stäuben dieser Art sind bei Web- und Strickmaschinen insbesondere unvermeidbare Liefer-, Brems- und Überwachungseinrichtungen für Fäden aller Art sowie zu deren Führung, Umlenkung und Kontrolle bestimmte Organe wie Fadenösen oder Leitstäbe. Da die meisten Garnqualitäten, vor allem aber Baumwollfäden, eine starke Flusenbildung bewirken, lagern sich die Flusen leicht an anderen Machinenelementen ab, wo sie allmählich wachsende Büschel bzw. Klumpen bilden und dadurch die Funktion der jeweiligen Textilmaschine beeinträchtigen können. Es ist daher allgemein bekannt, Textilmaschinen der verschiedensten Art mit Entstaubungsvorrichtungen auszurüsten, um entstehende Stäube möglichst bereits vor ihrer Ablagerung abzuführen.Permanent sources of this type of dust are in weaving and knitting machines especially unavoidable delivery, braking and monitoring equipment for Threads of all kinds as well as organs designed to guide, deflect and control them such as thread eyelets or guide rods. Since most yarn qualities, but especially cotton threads, cause a strong lint formation, the lint build up easily other machine elements, where they gradually grow clumps or clumps form and thereby impair the function of the respective textile machine can. It is therefore generally known to use textile machines of all kinds Equip dedusting devices in order to pre-create dust remove their deposit.

Die bei Textilmaschinen bisher bekannt gewordenen Entstaubungsvorrichtungen arbeiten durchweg mit Blas- und/oder Absaugeinrichtungen (z. B. DE 79 26 685 U1, DE 32 19 467 A1, US 3 422 640, EP 0 531 019 B1). Diese weisen z. T. aufwendige Luftverteileranordnungen auf, um an möglichst vielen Orten der jeweiligen Textilmaschine Blas- und/oder Saugdüsen anordnen zu können. Bekannt sind in diesem Zusammenhang auch in Fadenliefervorrichtungen integrierte Entstaubungsvorrichtungen (z. B. EP 1 053 196 B1, WO 01/18295) und Entstaubungsvorrichtungen, die vor allem diejenigen Bereiche einer Rundstrickmaschine staubfrei halten sollen, an denen die textilen Fäden durch Strickwerkzeuge zu Maschen verarbeitet werden (z. B. WO 95/09259, EP 0816 546 A2).The dedusting devices known to date in textile machines consistently work with blowing and / or suction devices (e.g. DE 79 26 685 U1, DE 32 19 467 A1, US 3 422 640, EP 0 531 019 B1). These have z. T. elaborate Air distribution arrangements on to as many locations of the respective textile machine To be able to arrange blowing and / or suction nozzles. Are known in this Connection also dedusting devices integrated in thread delivery devices (e.g. EP 1 053 196 B1, WO 01/18295) and dedusting devices that keep all those areas of a circular knitting machine dust-free where the textile threads are processed into stitches by knitting tools (e.g. WO 95/09259, EP 0816 546 A2).

Entstaubungsvorrichtungen dieser Art sind daher technisch aufwendig und mit einem hohen Energieverbrauch zur Erzeugung von Druck- und/oder Saugluft verbunden. Blas- und/oder Saugdüsen erschweren außerdem häufig den Zugang zu den Funktionsteilen, was deren Reparatur und Wartung erschwert.Dedusting devices of this type are therefore technically complex and with one high energy consumption for generating compressed and / or suction air. Blow and / or suction nozzles also often make access to the functional parts more difficult, which makes their repair and maintenance difficult.

Daneben sind Vorrichtungen bekannt, die dem Zweck dienen, an bewegten Materialbahnen wie z. B. Papier-, Textil- oder Kunststoffbahnen anhaftende Stäube dadurch zu entfernen, daß die Materialbahnen vor ihrem Einlauf in eine Absaugstation mit Hilfe von Elektroden elektrostatisch aufgeladen und/oder entladen werden (z. B. WO 91/12095, DE 41 20 973 A1, DE 100 18 010 A1, DE 195 25 453 A1,
DE 197 11 342 A1). Hierbei wird das physikalische Phänomen berücksichtigt, daß sowohl elektrisch nicht leitende Materialbahnen als auch in der Luft dispergierte Staubpartikel häufig durch Kontakt- und/oder Reibungselektrizität elektrostatisch aufgeladen werden und bei entgegengesetzten Polaritäten besonders starke Haftkräfte entstehen. Die Behandlung der Materialbahnen mit Lade- und/oder Entladeelektroden soll die Materialbahnen und die an ihnen haftenden Stäube daher elektrostatisch neutralisieren und dadurch die elektrostatischen Haftkräffte reduzieren. Mit derartigen Vorrichtungen lassen sich allerdings nur Stäube entsorgen, die bereits auf einer Materialbahn, wie z. B. einem fertigen Web- oder Strickstoff abgeschieden sind. Bei Textilmaschinen insbesondere durch Staub- und Faserflug verursachten Probleme lassen sich mit derartigen Vorrichtungen nicht lösen.In addition, devices are known which serve the purpose of moving on material webs such. B. remove paper, textile or plastic webs of adhering dusts by electrostatically charging and / or discharging the webs of material before they enter a suction station with the aid of electrodes (e.g. WO 91/12095, DE 41 20 973 A1 , DE 100 18 010 A1, DE 195 25 453 A1,
DE 197 11 342 A1). Here, the physical phenomenon is taken into account that both electrically non-conductive material webs and dust particles dispersed in the air are often electrostatically charged by contact and / or frictional electricity, and particularly strong adhesive forces are created with opposite polarities. The treatment of the material webs with charging and / or discharging electrodes should therefore electrostatically neutralize the material webs and the dusts adhering to them and thereby reduce the electrostatic adhesive forces. With such devices, however, can only dispose of dusts that are already on a material web, such as. B. a finished woven or knitted fabric. In textile machines, in particular problems caused by dust and fiber fly cannot be solved with such devices.

Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung das technische Problem zugrunde, eine Entstaubungsvorrichtung für Textilmaschinen, insbesondere Strickmaschinen zu schaffen, die keine komplizierten Luftführungen erfordert, daher kontruktiv weniger aufwendig als bekannte Entstaubungsvorrichtungen ist und mit vergleichsweise klein dimensionierten Gebläsen für Blas- und/oder Saugzwecke auskommt.Based on this prior art, the present invention is technical problem, a dedusting device for textile machines, in particular to create knitting machines that do not have complicated air ducts requires, therefore, less expensive than known dedusting devices is and with comparatively small-sized fans for blowing and / or Suction purposes.

Zur Lösung diese Problems schlägt die Erfindung eine Entstaubungsvorrichtung vor, die wenigstens ein elektrostatisch aufladbares Staub-Sammelelement und ein Mittel zur Abführung von mit dem Staub-Sammelelement gesammeltem Staub enthält.To solve this problem, the invention proposes a dedusting device, the at least one electrostatically chargeable dust collecting element and a means for Removal of dust collected with the dust collecting element contains.

Die Erfindung geht von dem Gedanken aus, elektrisch geladene Staubpartikel mit Hilfe eines elektrostatisch aufgeladenen Sammelelements anzuziehen und den angesammelten Staub dann vom Sammelelement zu entfernen. Bei einer besonders bevorzugten Ausgestaltung der Erfindung wird hierfür ein bewegtes Band verwendet. Dieses Band wird an einer Aufladungsstation elektrisch aufgeladen, damit es bei seinem Transport längs einer vorgegebenen Bahn Staub aus der umgebenden Atmosphäre aufnimmt bzw. aufgrund elektrischer Anziehungskräfte anzieht. Außerdem wird das Band an einer in Bewegungsrichtung hinter der Aufladungsstation angeordneten Entladungsstation elektrisch neutralisiert, um den auf ihm angesammelten Staub wieder abzulösen und dann z. B. mit Hilfe einer Saugeinrichtung abführen zu können. Das erfindungsgemäße Staub-Sammelelement kann daher eine Vielzahl der bisher erforderlichen Saug- und/oder Blasdüsen ersetzen, so daß im Prinzip nur eine einzige zentrale Absaugeinrichtung zur Abführung der gesammelten Stäube benötigt wird. The invention is based on the idea of having electrically charged dust particles With the help of an electrostatically charged collecting element and the accumulated Then remove dust from the collecting element. In a particularly preferred Embodiment of the invention, a moving belt is used for this. This tape is electrically charged at a charging station so that it can be transported takes dust from the surrounding atmosphere along a given path or attracts due to electrical attraction. In addition, the tape is in one Direction of movement behind the charging station arranged discharge station electrically neutralized to remove the dust that has accumulated on it and then z. B. with the help of a suction device. The invention Dust collecting element can therefore be a variety of previously required Replace suction and / or blowing nozzles, so that in principle only a single central one Suction device for removing the collected dust is required.

B. an einem zweiten, an den Stützen 7 montierten und in Fig. 1 ebenfalls nur geschnitten angedeuteten Tragring 11 befestigt, der ebenfalls koaxial zur Drehachse 3 angeordnet ist. Die Fadenliefervorrichtung 9, 10 dienen an nicht näher dargestellten Strickstellen bzw. Stricksystemen der Rundstrickmaschine zur Zuführung von in Fig. 1 gestrichelt dargestellten Fäden 12 zu den Strickwerkzeugen, wobei diese Fäden 12 von üblichen Vorratsspulen abgewickelt werden, die an einem weiteren Tragring der Rundstrickmaschine oder auch an einem neben der Rundstrickmaschine aufgestellten Spulengatter gelagert sein können. Das genaue Einlegen der Fäden 12 in die Strickwerkzeuge wird mit Hilfe von Fadenführern sichergestellt, die an einem auf der Grundplatte 6 abgestützten, mit der Drehachse 3 koaxialen Fadenführerring 14 befestigt sind.On a base plate 6 of the frame 1, a plurality of vertical supports 7 are supported a support cross 8a arranged above the circular knitting machine, which in consists essentially of a plurality of radially extending support arms 8b, which in the Center are connected by a disc. On the support cross 8a is in not shown in detail, only in Fig. 1 indicated, coaxial to Axis of rotation 3 arranged support ring 8 suspended on the yarn delivery devices 9 are attached.

    Rundstrickmaschinen dieser Art sind dem Fachmann allgemein bekannt (z. B. DE 79 26 865 U1, DE 36 28 851 A1) und brauchen daher nicht näher erläutert werden.Circular knitting machines of this type are generally known to the person skilled in the art (e.g. DE 79 26 865 U1, DE 36 28 851 A1) and therefore do not need to be explained in more detail.

    Die beschriebene Rundstrickmaschine ist erfindungsgemäß mit einer Entstaubungsvorrichtung ausgerüstet. Diese enthält im Ausführungsbeispiel ein Staub-Sammelelement 16 in Form eines aus einem hochohmigen Material hergestellten, endlosen Bandes, das in Fig. 2 strichpunktiert dargestellt ist. Das Sammelelement 16 liegt den äußeren Mantelflächen einer Mehrzahl von Führungsrollen 17 an, die an Halterungen 18 drehbar gelagert sind und sich vorzugsweise um zur Drehachse 3 parallele Achsen drehen können. Die Führungsrollen 17 sind wie die Fadenliefervorrichtungen 9 um die Drehachse 3 herum verteilt und zweckmäßig in einer Ebene angeordnet, wobei die Halterungen 18 an demselben Tragkreuz 8a wie der Tragring 8 befestigt sind. Eine der Führungsrollen 17a ist außerdem vorzugsweise als Antriebsrolle ausgebildet. Diese Antriebsrolle 17a ist z. B. auf der Antriebwelle 19 eines elektrischen Antriebsmotors 20 oder dgl. befestigt, wodurch das Sammelelement 16 in einer ausgewählten Drehrichtung und in Fig. 2 z. B. im Gegenuhrzeigersinn (Pfeil v) in eine um die Drehachse 3 umlaufende Dreh- bzw. Transportbewegung versetzt werden kann.The circular knitting machine described is equipped according to the invention with a dedusting device. In the exemplary embodiment, this contains a dust collecting element 16 in the form of an endless band made of a high-resistance material, which is shown in broken lines in FIG. 2. The collecting element 16 lies against the outer lateral surfaces of a plurality of guide rollers 17 which are rotatably mounted on brackets 18 and can preferably rotate about axes parallel to the axis of rotation 3. The guide rollers 17, like the thread delivery devices 9, are distributed around the axis of rotation 3 and expediently arranged in one plane, the brackets 18 being fastened to the same support cross 8a as the support ring 8. One of the guide rollers 17a is also preferably designed as a drive roller. This drive roller 17a is, for. B. attached to the drive shaft 19 of an electric drive motor 20 or the like. As a result, the collecting element 16 in a selected direction of rotation and in Fig. 2 z. B. counterclockwise (arrow v ) in a rotating around the axis of rotation 3 or transport movement.

    Das Staub-Sammelelement 16 ist den Fadenliefervorrichtungen 9 vorzugsweise derart zugeordnet, daß es auf einer Bewegungsbahn umläuft, die etwa in derselben Ebene liegt, in der auch die Fadenliefervorrichtungen 9 angeordnet sind, wobei die Bewegungsbahn außerdem vorzugsweise dicht an den Außenseiten der Fadenliefervorrichtungen 9 verläuft.The dust collecting element 16 is preferably the thread delivery devices 9 assigned that it revolves on a trajectory that is approximately in the same plane lies in which the yarn delivery devices 9 are arranged, the path of movement also preferably close to the outer sides of the thread delivery devices 9 runs.

    Wie insbesondere Fig. 2 zeigt, ist dem bandförmigen Sammelelement 16 eine zur elektrostatischen Aufladung bestimmte Station 21 zugeordnet, die wenigstens eine Ladeelektrode 22 enthält (vgl. auch Fig. 3), mittels derer das Sammelelement 16 je nach Fall positiv oder negativ aufgeladen werden kann. An einer in Bewegungsrichtung kurz vor der Station 21 liegenden Stelle ist außerdem ein Mittel zur Abführung von Staub vorgesehen, das im Ausführungsbeispiel eine zur Entladung des Sammelelements 16 bestimmte, wenigstens eine Entladeelektrode 23 aufweisende Station 24 (Fig. 2 und 4) und eine Staub-Absaugeinrichtung 25 (Fig. 2 und 5) enthält, die in Bewegungsrichtung des Sammelements 16 zweckmäßig zwischen den beiden Elektroden 22 und 23 angeordnet ist. Wie Fig. 2 zeigt, weist die Absaugeinrichtung 25 z. B. zwei Absaughauben 26, 27 auf, die auf entgegengesetzen Breitseiten des Sammelbandes 16 angeordnet und diesem mit ihren offenen Seiten zugewandt sind, während die Rückseiten der Absaughauben 26, 27 über Rohrleitungen 28 an ein nicht dargestelltes Sauggebläse angeschlossen sind, das in Richtung der in Fig. 5 eingezeichneten Pfeile wirkt.As shown in FIG. 2 in particular, the band-shaped collecting element 16 is one for electrostatic charge assigned to specific station 21, the at least one Charging electrode 22 contains (see also Fig. 3), by means of which the collecting element 16 each can be charged positively or negatively after case. On one in the direction of movement shortly before station 21 is also a means of removal provided by dust, which in the exemplary embodiment is used to discharge the Collection element 16 determined, having at least one discharge electrode 23 Contains station 24 (Fig. 2 and 4) and a dust extraction device 25 (Fig. 2 and 5), expediently in the direction of movement of the collecting element 16 between the two Electrodes 22 and 23 is arranged. As shown in Fig. 2, the suction device 25 z. B. two suction hoods 26, 27 on the opposite broad sides of the Collection belt 16 arranged and facing this with their open sides, while the rear sides of the suction hoods 26, 27 via pipes 28 to a not Suction fan shown are connected in the direction shown in Fig. 5 Arrows works.

    Das Sammelelement 16 besteht vorzugsweise aus einem hochohmigen Material wie z. B. Polyvinylchlorid (PVC) oder Gummi. Die Hochohmigkeit dient dem Zweck, eine mittels der Ladeelektrode 22 auf einen bestimmten Abschnitt des Sammelelements 16 aufgebrachte elektrische Ladung möglichst so lange auf diesem Abschnitt zu halten, bis er bei seinem Transport in Richtung des Pfeils v zusammen mit der auf ihm befindlichen elektrischen Ladung die Entladeelektrode 23 erreicht. Dadurch wird vermieden, daß zwischen den beiden Elektroden 22, 23 eine erneute Aufladung des Sammelelements 16 vorgenommen werden muß, um durch Selbstentladung oder dgl. verloren gegangene Aufladungen auszugleichen.The collecting element 16 is preferably made of a high-resistance material such as. B. polyvinyl chloride (PVC) or rubber. The high impedance serves the purpose of holding an electrical charge applied to a specific section of the collecting element 16 by means of the charging electrode 22 as long as possible on this section until it, together with the electrical charge located on it, transports it in the direction of the arrow v when it is transported 23 reached. This avoids the need for recharging of the collecting element 16 between the two electrodes 22, 23 in order to compensate for lost charges due to self-discharge or the like.

    Die Wirkungsweise der beschriebenen Rundstrickmaschine ist im wesentlichen wie folgt:The operation of the circular knitting machine described is essentially like follows:

    Beim Arbeiten der Rundstrickmaschine werden die Elektroden 22, 23 und die Station 24 eingeschaltet. Außerdem wird mittels des Antriebsmotors 20 ein Umlaufen des Sammelelements 16 in Richtung des Pfeils v (Fig. 2) auf einer Bewegungsbahn herbeigeführt, die durch die Lage der Führungs- und/oder Antriebsrollen 17, 17a vorgegeben ist. Gleichzeitig wird das Sammelelement 16 mit Hilfe der Ladeelektrode 22 positiv oder negativ aufgeladen, so daß im weiteren Verlauf elektrisch geladene, kontinuierlich hinter einander liegende Abschnitte des Sammelelements 16 in Richtung der Entladeelektrode 23 wandern und auf dem Weg dorthin alle im Bereich des Sammelelements 16 befindlichen, eine entgegengesetzte Polarität aufweisende oder entgegengesetzt polarisierte Staubpartikel elektrisch anziehen. Die angezogenen Staubpartikel bleiben dann am Sammelelement 16 haften, bis die zugehörigen Bandabschnitte die Entladungsstation 24 erreichen. Das Sammelelement 16 wird in dieser mit Hilfe der Entladeelektrode 23 entladen bzw. elektrisch neutralisiert, so daß die elektrische Haftkraft wegfällt und die mitgeführten Staubpartikel nur noch vergleichsweise lose am Sammelelement 16 haften. Die einzelnen Bandabschnitte werden dann der in Transportrichtung hinter der Entladungsstation 24 angeordneten Absaugvorrichtung 25 zugeführt, wo sie in den Wirkungsbereich der Absaughauben 26, 27 gelangen und daher von beiden Breitseiten her von anliegenden Staubpartikeln befreit werden, bevor sie wieder in die Ladungsstation 21 einlaufen und der beschriebene Zyklus erneut beginnt. Dabei ist der in Richtung des Pfeils v gemessene Weg von der Entladeelektrode 23 bis zur Ladeelektrode 22 möglichst kurz, damit stets nur ein kleiner Umfangsabschnitt des Sammelelements 16 nicht zur Sammlung und zum Transport von Staub zur Verfügung steht.When the circular knitting machine is working, the electrodes 22, 23 and the station 24 are switched on. In addition, the drive motor 20 causes the collecting element 16 to rotate in the direction of the arrow v (FIG. 2) on a movement path which is predetermined by the position of the guide and / or drive rollers 17, 17a. At the same time, the collecting element 16 is charged positively or negatively with the aid of the charging electrode 22, so that in the further course electrically charged, continuously successive sections of the collecting element 16 migrate in the direction of the discharge electrode 23 and on the way there all those located in the area of the collecting element 16, Electrically attract dust particles of opposite polarity or polarization. The attracted dust particles then adhere to the collecting element 16 until the associated belt sections reach the discharge station 24. The collecting element 16 is discharged or electrically neutralized in the latter with the aid of the discharge electrode 23, so that the electrical adhesive force is eliminated and the dust particles carried are only relatively loosely adhering to the collecting element 16. The individual belt sections are then fed to the suction device 25 arranged behind the discharge station 24 in the transport direction, where they reach the effective area of the suction hoods 26, 27 and are therefore freed of dust particles from both broad sides before they enter the loading station 21 again and the like described cycle begins again. The path measured in the direction of arrow v from the discharge electrode 23 to the charging electrode 22 is as short as possible, so that only a small peripheral section of the collecting element 16 is always not available for collecting and transporting dust.

    Wird für das Sammelelement 16 ein Material verwendet, das nicht ausreichend hochohmig ist, können längs seiner Bewegungsbahn natürlich auch mehrere Aufladungsstationen 21 vorgesehen sein.If a material is used for the collecting element 16 which is not sufficient is high-resistance, of course, several charging stations along its movement path 21 may be provided.

    Zur Aufladung des bandförmigen Sammelelements 16 kann vorgesehen sein, eine der Ladeelektrode 22 unmittelbar gegenüberliegende Führungsrolle 17b (Fig. 2) aus einem derartigen Material wie z.B. Plexiglas herzustellen, daß sie als Erregerrolle wirkt. Darunter wird verstanden, daß die Führungsrolle 17b und das Sammelelement 16 hierbei durch Berührungselektrizität, d.h. bereits aufgrund ihrer innigen Berührung (bzw. Reibung) und der nachfolgenden Trennung entgegengesetzt aufgeladen werden. Die Ladeelektrode 22 kann in diesem Fall als eine Spitzenelektrode ausgebildet werden, die von der Führungsrolle 17b durch Influenz mit entgegengesetzter Polarität aufgeladen wird und das an ihr vorbeilaufende, bandförmige Sammelelement 16 daher durch Spitzen- bzw. Koronaentladung zusätzlich entsprechend auflädt. Das Sammelelement 16 kann dann, wie oben beschrieben ist, auf seinem Weg zur Entladeelektrode 23 alle entgegengesetzt zu ihm geladenen Staubpartikel elektrisch anziehen. Alternativ könnte die Führungsrolle 17b aber auch aus einem elektrisch leitenden Material bestehen und als Gegenelektrode zur Ladeelektrode wirken.To charge the band-shaped collecting element 16, one of the Charging electrode 22 immediately opposite guide roller 17b (Fig. 2) from a such material as e.g. To produce plexiglass that it acts as a pathogen. This means that the guide roller 17b and the collecting element 16 here by touch electricity, i.e. already because of their intimate touch (or friction) and the subsequent separation are charged opposite. In this case, the charging electrode 22 can be designed as a tip electrode by the guide roller 17b due to influence with opposite polarity is charged and therefore the band-shaped collecting element 16 running past it additionally charged by peak or corona discharge. The collecting element 16 can then, as described above, on its way to the discharge electrode 23 Electrically attract all dust particles charged opposite to it. alternative the guide roller 17b could also be made of an electrically conductive material exist and act as a counter electrode to the charging electrode.

    Die beschriebene Entstaubungsvorrichtung bringt den wesentlichen Vorteil mit sich, daß für eine Vielzahl von Liefervorrichtungen 9 nur ein gemeinsames, Staub anziehendes Band benötigt wird und die Abführungs des Staubs an einer einzigen zentralen Stelle, d.h. hier am Ort der Absaugeinrichtung 25 erfolgen kann. Außerdem ist klar, daß für den Fall, daß die Fadenliefervorrichtungen 9 und 10 (Fig. 1) in mehreren Ebenen angeordnet sind, jeder einzelnen dieser Ebenen eine separate Entstaubungsvorrichtung zugeordnet sein könnte, die analog zur Fig. 1 bis 5 wenigstens je ein Sammelelement 16, je eine Lade- bzw. Entladeelektrode 22, 23 und eine Absaugeinrichtung 25 aufweist.The dedusting device described has the essential advantage that that for a variety of delivery devices 9 only one common, dust-attracting Belt is needed and the removal of the dust at a single central Position, i.e. can take place here at the location of the suction device 25. It's also clear that in the event that the thread delivery devices 9 and 10 (Fig. 1) in several Levels are arranged, each of these levels a separate dedusting device could be assigned, which is analogous to FIGS. 1 to 5 at least one Collecting element 16, each a charging or discharging electrode 22, 23 and a suction device 25 has.

    Wird die beschriebene Entstaubungsvorrichtung bei einer Flachstrickmaschine anstatt bei einer Rundstrickmaschine eingesetzt, dann wäre es beispielsweise möglich, das bandförmige Sammelelement 16 anstatt auf einer Kreisbahn auf einer langgestreckten, im wesentlichen geraden Bahn mit zwei parallelen Trums umlaufen zu lassen. Dabei wäre es außerdem möglich, die Aufladung des Sammelelements 16 an einem Umlenkpunkt und die Entladung des Sammelelements 16 am anderen Umlenkpunkt des Schlittens der Falchstrickmaschine vorzunehmen und das Sammelelement in einer Höhe anzuordnen, in der die stärkste Staubentwicklung zu erwarten ist.If the described dedusting device in a flat knitting machine instead used in a circular knitting machine, then it would be possible, for example, that band-shaped collecting element 16 instead of on a circular path on an elongated, to run essentially straight track with two parallel runs. there it would also be possible to charge the collecting element 16 at a deflection point and the discharge of the collecting element 16 at the other deflection point of the Carriage of the false knitting machine and the collecting element in one To be arranged at the height at which the greatest dust formation is to be expected.

    Anstelle eines bewegten Bandes können auch andere Sammelelemente vorgesehen werden, insbesondere solche in Form von aufladbaren Sammelplatten oder dgl., an denen sich geladene oder in einem elektrischen Feld polarisierte Staubpartikel niederschlagen. Solche Platten könnten außerdem einzelnen Funktionsteilen der Textilmaschine, insbesondere einer einzelnen Fadenliefervorrichtung zugeordnet werden. Die Abführung des Staubs kann dabei dadurch erfolgen, daß die Sammelplatten von Zeit zu Zeit elektrisch neutralisiert werden, um die Staubpartikel ggf. aufgrund ihrer Schwerkraft herabfallen zu lassen oder auf sonstige Weise abzuführen.Instead of a moving belt, other collecting elements can also be provided are, in particular those in the form of rechargeable collecting plates or the like dust particles that are charged or polarized in an electric field. Such plates could also be individual functional parts of the textile machine, in particular be assigned to a single thread delivery device. The The removal of the dust can take place in that the collecting plates of time to be electrically neutralized at the time to remove the dust particles due to their To let gravity fall or to dissipate it in any other way.

    Im übrigen können zur Auf- und Entladung der Sammelelemente Elektroden und diesen zugeordnete Einrichtungen vorgesehen werden, wie es in Verbindung mit der Ablösung von Stäuben von textilen Bahnen oder dgl. allgemein bekannt ist (vgl. die eingangs angegebenen Dokumente). Die Größe der ggf. an die Elektroden anzulegenden Hochspannungen ist dabei anhand des Einzelfalls, insbesondere sich im Einzelfall ergebenden Staubentwicklung zu wählen. Die dazu erforderlichen elektrischen Zuleitungen sind in Fig. 3 und 4 mit den Bezugszeichen 30 und 31 angedeutet.Otherwise, electrodes can be used to charge and discharge the collecting elements these associated facilities are provided, as in connection with the Detachment of dusts from textile webs or the like is generally known (cf. the documents specified at the beginning). The size of the electrodes to be attached if necessary High voltages are based on the individual case, especially in the individual case resulting dust to choose. The necessary electrical Supply lines are indicated in FIGS. 3 and 4 with the reference numerals 30 and 31.

    Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt, das auf vielfache Weise abgewandelt werden könnte. Beispielsweise wäre es für den Fall, daß Stäube unterschiedlicher Polaritäten abzuführen sind, auch möglich, Entstaubungsvorrichtungen vorzusehen, die Sammelelemente mit entsprechend unterschiedlichen Polaritäten aufweisen und/oder den Stäuben durch starke elektrische Felder eine ausgewählte Polarität zu geben. Weiter könnten die Sammelelemente anderen als den beschriebenen Fadenliefervorrichtungen zugeordnet werden. Grundsätzlich ist es möglich, eine der oben beschriebenen Staub- und Flaumsammeleinrichtung entsprechende Einrichtung an allen Fadenumlenkungen und auch im Bereich der Fadenführer anzubringen. Zusätzlich zur Absaugeinrichtung 25 könnte außerdem wenigstens eine Blaseinrichtung vorgesehen werden, um das Ablösen der Stäube von einem zugeordneten Sammelelement zu beschleunigen bzw. zu verstärken. Je nach Staubanfall besteht eine weitere Möglichkeit darin, in Transportrichtung des Sammelelements 16 hinter der Aufladungsstation zwei oder mehrere Entladungsstationen und Absaugeinrichtungen vorzusehen, um dadurch die Abführung des angesammelten Staubs zu verbessern. Außerdem können andere als die aus Fig. 1 und 2 ersichtlichen Strickmaschinentypen mit den erfindungsgemäßen Entstaubungsvorrichtungen ausgerüstet werden. Dabei ist in allen Fällen klar, daß die Bezeichnung "Band" alle für den beschriebenen Zweck geeigneten Querschnitte, d.h. insbesondere rechteckige, quadratische oder auch runde Querschnitte einschließen soll. Schließlich versteht sich, daß die verschiedenen Merkmale auch in anderen als den dargestellten und beschriebenen Kombinationen angewendet werden können.The invention is not limited to the exemplary embodiment described, which is based on could be modified in many ways. For example, in the event that Dusts of different polarities can also be removed, dedusting devices are also possible to provide the collecting elements with correspondingly different Have polarities and / or the dusts due to strong electrical fields to give selected polarity. Furthermore, the collection elements could be other than be assigned to the thread delivery devices described. Basically is it is possible to use one of the dust and fluff collecting devices described above appropriate device on all thread deflections and also in the area of Attach thread guide. In addition to the suction device 25 could also at least one blowing device can be provided to detach the dusts accelerate or amplify by an associated collecting element. ever after dust accumulation there is another possibility, in the direction of transport of the collecting element 16 behind the charging station two or more discharge stations and provide suction devices to thereby remove the improve accumulated dust. In addition, other than that of Fig. 1 and 2 apparent knitting machine types with the dedusting devices according to the invention be equipped. It is clear in all cases that the designation "Belt" means all cross sections suitable for the purpose described, i.e. in particular should include rectangular, square or even round cross sections. Finally it is understood that the various features in other than those shown and combinations described can be used.
