Abstract

The pneumatic dust-removing apparatus for yarn-supply carriers and thread-guide members of textile machines is characterised by filter-mesh walls, by means of which a dust-forming region is screened off completely or partially from the outside and through which the dust-laden air is conveyed out of the dust-forming region. The retention of fibres and fluff in the filter-mesh walls can be assisted by an electrical charging of these walls. …<IMAGE>…

Description

Die Erfindung betrifft eine Einrichtung zum pneumatischen Entstauben von Garnvorratsträgern und Fadenleitorganen von Textilmaschinen, mit mindestens einem einen Blasluftstrom in dem von den Garnvorratsträgern und Fadenleitorganen eingenommenen Staubbildungsbereich verursachenden Ventila­tor oder einer Blasdüse.The invention relates to a device for the pneumatic dedusting of yarn bobbins and thread guiding elements of textile machines, with at least one blower air flow in the dust forming area causing the yarn bobbins and thread guiding elements, or a blower nozzle.

Bei der Verarbeitung von Garnen und Fäden ist das Auf­treten von Faserflug unvermeidlich, sobald Garn oder Faden von Garnvorratsträgern abgezogen oder über Fadenleitorgane geführt wird. Dabei werden beim Fadenablauf lose Fasern oder bei der Fadenführung losgelöste Fasern freigesetzt. Um die Textilmaschinen und ihre zugeordneten Einrichtungen vor einer Verunreinigung und das Bedienungspersonal vor einer Belästigung durch Faserflug zu schützen, sind bereits zahlreiche Entstaubungseinrichtungen vorgeschlagen worden. Die beste Wirkung haben Einrichtungen, bei welchen die Fasern zunächst von freizuhaltenden Maschinenteilen abgeblasen und anschließend in eine Filtereinrichtung abgesaugt werden. Solche Einrichtungen haben aber den Nachteil, daß sie sehr aufwendig sind und der zu entstau­bende Bereich durch feste Wandungen begrenzt sein sollte. Dieser Aufwand ist im unmittelbaren Bereich der Garnver­arbeitungsstellen, beispielsweise an Strickmaschinen, gerechtfertigt, weniger dagegen an vorgeschalteten Zusatz­einrichtungen, wie Garnvorratsträgern, die durch eine solche Entstaubungseinrichtung merklich verteuert werden.In the processing of yarns and threads, the occurrence of fiber fly is inevitable as soon as the yarn or thread is drawn off from the thread supply bobbin or passed over thread guide elements. Loose fibers are released during the thread run-off or fibers detached during the thread guide. Numerous dedusting devices have already been proposed in order to protect the textile machines and their associated devices from contamination and the operating personnel from nuisance caused by fiber fly been. Devices in which the fibers are first blown off from machine parts to be kept clear and then sucked off into a filter device have the best effect. However, such devices have the disadvantage that they are very complex and the area to be dedusted should be limited by solid walls. This effort is justified in the immediate area of the yarn processing stations, for example on knitting machines, but less so on upstream additional devices, such as yarn storage bins, which are noticeably more expensive due to such a dedusting device.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Ein­richtung der eingangs genannten Art so auszubilden, daß sie nur einen relativ geringen Aufwand erforderlich macht, trotzdem aber eine ausreichende Entstaubung der Zusatz­geräte und einen Schutz benachbarter Einrichtungen gegen Verstaubung ergibt.The invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that it requires only relatively little effort, but nevertheless results in adequate dedusting of the additional devices and protection of adjacent devices against dusting.

Die gestellte Aufgabe wird mit der genannten Einrichtung erfindungsgemäß dadurch gelöst, daß der Staubbildungs­bereich an seiner Peripherie mindestens bereichsweise durch mindestens eine Filtergitterwandung begrenzt ist, gegen welche der aus dem Staubbildungsbereich austretende Blasluftstrom gerichtet ist. Vorteilhafterweise kann hierbei die Filtergitterwandung quer zu dem Blasluftstrom angeordnet sein.The stated object is achieved according to the invention with the above-mentioned device in that the dust formation area on its periphery is at least partially delimited by at least one filter grid wall, against which the blowing air stream emerging from the dust formation area is directed. The filter grid wall can advantageously be arranged transversely to the blown air flow.

Bei einer erfindungsgemäß ausgebildeten Einrichtung werden die Garnvorratsträger und anschließende Fadenleitorgane in an sich bekannter Weise durch Abblasen z. B. mittels Ven­tilatoren saubergehalten. Die abgeblasenen Fasern werden aber an einfachen Filtergitterwandungen festgehalten, die keinen teuren konstruktiven Aufbau bedingen, sich leicht an unterschiedliche bauliche Gegebenheiten anpassen lassen und von denen die Fasern sich nachträglich mit einem Staubsauger leicht absaugen oder in einem gesonderten Staubsammelraum abbürsten lassen. Der besondere Vorteil der Einrichtung besteht darin, daß der Staubbildungsbe­reich nicht durch feste Wandungen abgegrenzt werden muß, welche die Bedienung der zu entstaubenden Garnvorratsträ­ger und Fadenleitorgane erschweren würden. Bei einer Ein­richtung gemäß der vorliegenden Erfindung können die Fil­tergitterwandungen beispielsweise aus mehreren vorhang­artig verschiebbar angeordneten und sich gegenseitig überlappenden Filtergitterbahnen bestehen, die hängend an­geordnet sind und die sich im Bedarfsfalle auch leicht beiseiteschieben lassen.In a device designed according to the invention, the yarn supply carriers and subsequent thread guide members are blown off in a manner known per se, for. B. kept clean by means of fans. The blown-off fibers are held onto simple filter grid walls, however does not require an expensive construction, can be easily adapted to different structural conditions and from which the fibers can be easily vacuumed with a vacuum cleaner or brushed off in a separate dust collection room. The particular advantage of the device is that the dust formation area does not have to be delimited by solid walls, which would make it difficult to operate the yarn supply carriers and thread guide elements to be dusted. In the case of a device according to the present invention, the filter grid walls can consist, for example, of a plurality of filter grid webs which can be displaced in a curtain-like manner and overlap one another, which are arranged in a hanging manner and which, if necessary, can also be easily pushed aside.

Mit einer preiswerten Entstaubungseinrichtung gemäß der Erfindung lassen sich beispielsweise auch nur bestimmte Bereiche gegen Faserflug abschirmen, etwa einzelne Strick­maschinen gegenüber benachbart angeordneten Garnständern. Solche Garnständer werden häufig mittels auf bewegten Trägern montierter Ventilatoren abgeblasen, und hier kön­nen durch Filtergitterwandungen gemäß der Erfindung nur Abschnitte der Peripherie solcher Spulengitter abgeschirmt werden, in welchen sich Bedienungspersonen aufhalten oder an denen sich eine Textilmaschine befindet. Das Filter­gitter kann zweckmäßig aus einem elektrisch aufladbaren Kunststoffmaterial bestehen, das eine zusätzliche Anzieh­wirkung auf den Faserflug ausübt. Das Filtergitter kann aber auch aus Metalldraht bestehen und an ein das Halten der angesetzten Fasern begünstigendes Spannungspotential gelegt werden. Versuche haben aber gezeigt, daß die Fil­tergitter auch ohne Aufladung und auch ohne aufgerauhte Oberfläche angeblasenen Faserflug gut halten, und daß der Faserflug nachträglich leicht abgesaugt werden kann.With an inexpensive dedusting device according to the invention, it is also possible, for example, to shield only certain areas from fiber fly, for example individual knitting machines from yarn stands arranged adjacent to one another. Such yarn stands are often blown off by fans mounted on moving supports, and here only sections of the periphery of such bobbin grids, in which operators are located or on which a textile machine is located, can be shielded by filter grid walls according to the invention. The filter grid can expediently consist of an electrically chargeable plastic material, which exerts an additional attraction on the fiber flight. However, the filter grid can also consist of metal wire and be applied to a voltage potential which favors the holding of the attached fibers. Experiments have shown, however, that the filter grids can also be charged without being roughened Keep the surface of the blown fiber fly well and that the fiber fly can be easily vacuumed afterwards.

Fig. 1 zeigt schematisch eine Rundstrickmaschine 10 und ein daneben aufgestelltes Spulengatter 11 in bekannter Rundbauweise. Im Zentrum des Spulengatters 11 ist ein mit Blasdüsen 12 besetztes Rohr 13 vertikal ausgerichtet und durch einen Elektromotor 14 drehbar gelagert angeordnet, in welches Druckluft eingeleitet wird. Mittels der Blas­düsen 12 werden die im Spulenständer 11 angeordneten Spulen 15, von denen der Faden 16 jeweils durch ein Faden­leitrohr 17 hindurch zur Rundstrickmaschine 10 hin abge­zogen wird, von Staub und lockeren Fasern befreit, die radial nach außen vom Spulenständer 11 weggeblasen werden. Um die Rundstrickmaschine 10 vor diesem Faserflug zu schützen, ist bei dem dargestellten Ausführungsbeispiel zwischen der Rundstrickmaschine und dem Spulenständer 11 eine Schirmwandung 18 aus einem Filtergitter 19 angeord­net. Es kann sich um eine ebene Schirmwandung handeln, in welcher das Filtergitter in einem Tragrahmen eingespannt ist, der auf Standfüßen ruht. Die Filtergitterwandung 18 kann aber auch entsprechend der Rundung der Peripherie des Spulenständers 11 oder der Strickmaschine 10 gekrümmt sein und an einem oberen, nicht dargestellten Tragrahmen auf­gehängt sein.Fig. 1 shows schematically a circular knitting machine 10 and a creel 11 placed next to it in a known circular design. In the center of the creel 11, a tube 13 filled with blowing nozzles 12 is aligned vertically and arranged rotatably by an electric motor 14, into which compressed air is introduced. By means of the blowing nozzles 12, the bobbins 15 arranged in the bobbin stand 11, from which the thread 16 is drawn through a thread guide tube 17 to the circular knitting machine 10, are freed from dust and loose fibers which are blown away radially outward from the bobbin stand 11. In order to protect the circular knitting machine 10 from this fiber fly, a screen wall 18 made of a filter grid 19 is arranged between the circular knitting machine and the bobbin stand 11 in the exemplary embodiment shown. It can be a flat screen wall, in which the filter grid is clamped in a support frame which rests on feet. The filter grid wall 18 can also be curved in accordance with the rounding of the periphery of the bobbin stand 11 or the knitting machine 10 and can be suspended from an upper support frame (not shown).

Fig. 4 zeigt einen Eckbereich eines aus Kunststoffdrähten oder aus Metalldrähten gewobenen, flexiblen Filtergitters 19, das mit einer oberen Tragleiste 20 versehen ist, in welchem Ringe 21 zum Aufhängen der Filtergitterwandung verankert sein können.Fig. 4 shows a corner region of a flexible filter grid 19 woven from plastic wires or from metal wires, which is provided with an upper support strip 20, in which rings 21 can be anchored for hanging the filter grid wall.

Die Fig. 2 und 3 zeigen in Seitenansicht und in Draufsicht wiederum ein rundes Spulengatter 11′, das in seinem Zen­trum umlaufende Blasdüsen 12′ zum Reinigen der Garnspulen 15′ aufweist. Anstelle der Blasdüsen 12′ könnten auch um­laufende Ventilatoren Verwendung finden. Das Spulengatter 11′ ist mit oberen ringförmigen Tragschienen 22 versehen, von denen eine in Fig. 2 dargestellt ist, an denen in zwei konzentrischen Ringebenen auf der Außenseite des Spulen­ gatters 11′ über den ganzen Umfang des Spulengatters mehrere Filtergitterbahnen 23 vorhangartig verschiebbar und sich gegenseitig überlappend aufgehängt sind. Die Filtergitterbahnen 23 sind an ihrer Unterseite mit einer Gewichtsleiste 24 beschwert oder sind an Schienen be­festigt. Die von den umlaufenden Blasdüsen 12′ in dem einen Staubbildungsbereich darstellenden Rundgatter 11′ von den Spulen 15′ und den von ihnen abgezogenen Fäden 16′ radial nach außen abgeblasenen Fasern bleiben an den Filtergitterbahnen 23 hängen, durch welche die abgeblasene Luft nach außen hindurchströmt. Die Filtergitterbahnen 23 lassen sich nach Betriebsschluß oder bei Schichtwechsel leicht mittels eines Staubsaugers reinigen.2 and 3 show in side view and in plan view, in turn, a round creel 11 ', which has circumferential blowing nozzles 12' for cleaning the yarn packages 15 '. Instead of the blow nozzles 12 'rotating fans could also be used. The creel 11 'is provided with upper annular support rails 22, one of which is shown in Fig. 2, on which in two concentric ring planes on the outside of the coil gates 11 'over the entire circumference of the creel several filter grid webs 23 can be moved like a curtain and are mutually overlapping suspended. The filter grid sheets 23 are weighted on their underside with a weight bar 24 or are attached to rails. The from the rotating blow nozzles 12 'in a dust-forming area circular gate 11' from the spools 15 'and the threads 16' they are drawn off radially to the outside blown fibers hang on the filter mesh webs 23 through which the blown air flows outwards. The filter grid sheets 23 can be easily cleaned by a vacuum cleaner after the end of operation or when changing shifts.

Wie Fig. 5 zeigt, kann ein Spulengatter 11˝ auch auf seiner Oberseite mittels einer leichten Filtergitterhaube 25 versehen werden, bei welcher das Filtergitter über ein nicht näher dargestelltes leichtes Rohrgestell gespannt ist. Die Filtergitterhaube 25 kann zur Erleichterung ihrer zum Reinigen erforderlichen Abnahme aus mehreren Teilen, beispielsweise aus zwei Hälften zusammengesetzt sein. Die Filtergitterhaube kann auch so konstruiert sein, daß an ihrem Tragrahmen die das Spulengatter 11˝ seitlich ab­schirmenden Filtergitterbahnen 23′ aufgehängt sind.5 shows, a coil creel 11ul can also be provided on its upper side by means of a light filter grille hood 25, in which the filter grille is stretched over a light tubular frame (not shown). The filter grille hood 25 can be composed of several parts, for example of two halves, in order to facilitate the removal required for cleaning. The filter grille hood can also be constructed so that the filter frame 11 'laterally shielding the filter grating sheets 23' are suspended from their support frame.

Die Filtergitterwandungen der Entstaubungseinrichtung las­sen sich nach Größe und Formgebung an alle möglichen Ab­messungen des ganz oder teilweise nach außen abzuschirmen­den Staubbildungsbereiches anpassen. Bei geradlinigen Spulengattern finden demnach entsprechend geradlinige Filtergitterwandungen Verwendung. Die Filtergitterwandun­gen können durch Anschluß an eine nicht dargestellte elek­trische Einrichtung oder bei Kunststoffmaterial durch ein­ faches Reiben mit einer elektrischen Ladung versehen wer­den, welche das Haften angeblasenen Faserfluges be­günstigt.The filter grid walls of the dedusting device can be adapted in size and shape to all possible dimensions of the dust formation area to be shielded entirely or partially from the outside. In the case of rectilinear coil gates, corresponding rectilinear filter grid walls are accordingly used. The filter grid walls can by connecting to an electrical device, not shown, or in the case of plastic material, by a multiple rubbing are provided with an electrical charge, which favors the sticking of the blown fiber flight.
