Description

Die Erfindung betrifft einen Flyer gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a flyer according to the preamble of patent claim 1.

Bei derartigen Spinnmaschinen ist die
die Spinnstellen abdeckende Tischplatte normalerweise waagerecht auf der Flügelbank aufliegend angeordnet. Um eine Beeinträchtigung der Flyerflügel durch Flockengebilde und Ansammlungen von Flug und anderen Verunreinigungen auf der Tischplatte zu vermeiden bzw. derartige Verunreinigungen zu beseitigen, sind z.B. an der der Bedienungsseite abgewandten Kante der Tischplatte eine Vielzahl von Blasdüsen angeordnet, mit denen die Verunreinigungen von der Tischplatte weggeblasen werden können.In such spinning machines
the table top covering the spinning positions is normally arranged horizontally on the wing bench. In order to prevent the flyer wings from being impaired by flakes and accumulations of flight and other contaminants on the tabletop, or to remove such contaminants, a large number of blowing nozzles are arranged, for example, on the edge of the tabletop facing away from the operating side, with which the contaminants are blown away from the tabletop can be.

Um eine derartige Blasvorrichtung wirkungsvoll betreiben zu können, ist eine relativ starke Druckluftquelle erforderlich, da über die gesamte Länge der Spinnmaschine an den einzelnen Blasdüsen ein entsprechender Luftdruck herrschen muß, was relativ energieaufwendig ist und damit zu einer Erhöhung der Betriebskosten führt.In order to be able to operate such a blowing device effectively, a relatively strong compressed air source is required, since a corresponding air pressure must prevail over the entire length of the spinning machine at the individual blowing nozzles, which is relatively energy-intensive and thus leads to an increase in operating costs.

Außerdem wurde bereits vorgeschlagen, die Tischplatte mittels eines Wanderbläsers von der Bedienungsseite des Flyers her, also vom von den Streckwerken entfernten Bereich des Flyers abzublasen, um Flug und andere Verunreinigungen oder Flockengebilde im Bereich der Streckwerke abzusaugen. Diese Lösung ist jedoch nicht zufriedenstellend, da hierbei Luftverwirbelungen entstehen, wodurch die Lunten im Bereich zwischen den Streckwerken und den Flyerflügeln in Vibration versetzt werden können, wodurch eine einwandfreie Vorgarnherstellung gestört wird.In addition, it has already been proposed to blow off the table top by means of a traveling blower from the operating side of the flyer, that is to say from the area of the flyer remote from the drafting devices, in order to suck off flight and other contaminants or flakes in the area of the drafting devices. However, this solution is unsatisfactory, since it creates air turbulence, which can cause the fuselages in the area between the drafting systems and the flyer wings to vibrate, which impairs proper roving production.

Außerdem ist es hierbei nachteilig, daß die Verunreinigungen entgegen der Luntentransportrichtung zunächst in den Streckwerksbereich geblasen werden, da sich auf diese Weise Verunreinigungen an den Lunten möglicherweise anlagern können, bevor die Verunreinigungen abgesaugt werden.In addition, it is disadvantageous here that the impurities are first blown into the drafting system area counter to the direction of the sliver transport, since in this way contaminations can possibly accumulate on the slips before the impurities are suctioned off.

Aufgrund der von dem Wanderblaser erzeugten Luftverwirbelungen lassen sich die Verunreinigungen darüber hinaus auch nur ungenügend absaugen.Due to the air turbulence generated by the traveling blower, the impurities can also be insufficiently extracted.

Aus der DE-C2-24 19 188 ist ein Flyer gemäss Oberbegriff des unabhängigen Anspruches bekannt. Blasluft wird unterhalb des Streckwerks auf einen Zwischenboden oberhalb der Flyerflügel geleitet, auf den die Lunten unter einem spitzen Winkel zulaufen. Ablagerungen auf dem Zwischenboden, die durch den Luftstrom aufgewirbelt werden, können sich an den Lunten anlagern, wodurch Dickstellen entstehen können.A flyer according to the preamble of the independent claim is known from DE-C2-24 19 188. Blown air is conducted below the drafting system to an intermediate floor above the flyer wings, to which the fuselages run at an acute angle. Deposits on the mezzanine floor, which are whirled up by the air flow, can accumulate on the fuses, which can cause thick spots.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Spinnmaschine der eingangs genannten Art zu schaffen, bei der die Verflugung, also die Ansammlung von Flug und anderen Verunreinigungen im Bereich freier Faserluntenabschnitte, die sich zwischen den Streckwerken und den Spinnstellen erstrecken, auf einfache und kostengünstige Weise vermieden werden kann.The present invention has for its object to provide a spinning machine of the type mentioned, in which the flying, i.e. the accumulation of flight and other contaminants in the area of free fiber sliver sections, which extend between the drafting units and the spinning stations, in a simple and inexpensive manner can be avoided.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Durch die erfindungsgemäß Vorgesehene geneigte Anordnung der Tischplatte läßt sich diese auf vereinfachte Weise sauberblasen. Dabei ist es insbesondere von Vorteil, daß die freien Faserluntenabschnitte im wesentlichen parallel zu der Tischplatte verlaufen, so daß die beim Sauberblasen der Tischplatte entstehende Luftströmung die freien Faserluntenabschnitte über ihre gesamte Lange gleichmäßig beeinflußt. Dabei ist die zum Sauberhalten der Tischplatte vorgesehene Luftstromung in etwa parallel zu den freien Luntenabschnitten, so daß diese nicht gestört werden.Due to the inclined arrangement of the table top provided according to the invention, this can be blown clean in a simplified manner. It is particularly advantageous that the free fiber sliver sections run substantially parallel to the table top, so that the air flow that arises when the table top is blown clean influences the free fiber sliver sections evenly over their entire length. It is the air flow provided for keeping the table top clean approximately parallel to the free sliver sections so that they are not disturbed.

Durch derartige im wesentlichen gleichbleibende, konstante Bedingungen beim Sauberblasen der Tischplatte laßt sich diese leicht und einfach sauberhalten, ohne daß die mit der Spinnmaschine erzeugten Faserlunten in ihrer Qualität beeinträchtigt werden.Such essentially constant, constant conditions when blowing the table top can be easily and simply kept clean without the need for Spinning machine-produced fiber slivers are impaired in their quality.

Ein vereinfachter Aufbau einer Spinnmaschine ist im Anspruch 2 beschrieben.A simplified structure of a spinning machine is described in claim 2.

Besonders vorteilhaft ist das Ausführungsbeispiel nach Anspruch 3.The embodiment according to claim 3 is particularly advantageous.

Durch die erfindungsgemäß vorgesehene, schräg angeordnete Tischplatte wird es ermöglicht, zum Sauberhalten der Tischplatte einen Wanderbläser zu verwenden, der vom Streckwerksbereich aus die Tischplatte sauberbläst, da sich die Blasdüsen des Wanderbläsers relativ nahe an der schrägen Tischplatte anordnen lassen und der Luftstrom die freien Luntenabschnitte praktisch nicht zu kreuzen braucht.The slanted table top provided according to the invention makes it possible to use a traveling blower to keep the table top clean, which blows the table top clean from the drafting system area, since the blowing nozzles of the traveling blower can be arranged relatively close to the inclined table top and the air flow practically the free sliver sections does not need to cross.

Erfindungsgemäß kann also mit einer Blasdüse eines Wanderbläsers die schräge Tischplatte energiesparend und wirkungsvoll gesäubert werden, wobei der vom Wanderbläser erzeugte Luftstrom etwa in Längsrichtung der Lunten bläst.According to the invention, the oblique table top can thus be cleaned in an energy-saving and effective manner with a blowing nozzle of a traveling blower, the air flow generated by the traveling blower blowing approximately in the longitudinal direction of the fuses.

Hierdurch läßt sich also erfindungsgemäß der Energiebedarf für das Sauberblasen der Spinnmaschine gering halten, da jeweils nur an den Blasdüsen des Wanderbläsers der für das Sauberblasen erforderliche Luftdruck erzeugt zu werden braucht. Es reicht somit, wenn nur an einer oder an wenigen Blasdüsen der erforderliche Luftdruck vorliegt, wodurch der benötigte Energiebedarf verringert wird. Darüber hinaus können die Reinigungsintervalle, in denen der Wanderbläser die Maschine periodisch oder nach Bedarf abfährt, an die jeweiligen Gegebenheiten beim Spinnen, insbesondere an das jeweils zu verarbeitende Material, das mehr oder weniger Verunreinigungen oder freie Fasern erzeugt, angepasst werden.In this way, according to the invention, the energy requirement for blowing the spinning machine clean can be kept low, since the air pressure required for blowing clean need only be generated at the blowing nozzles of the traveling blower. It is therefore sufficient if the required air pressure is present at only one or at a few blowing nozzles, as a result of which the required energy is reduced. In addition, the cleaning intervals in which the traveling blower periodically or as required can be adapted to the particular circumstances during spinning, in particular to the material to be processed in each case, which produces more or less impurities or free fibers.

Ein wesentlicher Vorteil der Erfindung ist es dabei, daß der Wanderbläser die Qualität der mit der Spinnmaschine erzeugten Faserlunten praktisch nicht beeinträchtigt, da der von ihm erzeugte Reinigungsluftstrom in Transportrichtung der Faserlunten verläuft, so daß er keine unerwünschten Kräfte auf die freien Faserluntenabschnitte ausübt, die möglicherweise zu Fehlverzügen oder zu Luntenbrüchen führen könnten.A major advantage of the invention is that the traveling blower practically does not adversely affect the quality of the fiber lunches produced with the spinning machine, since the cleaning air flow generated by it runs in the transport direction of the fiber lunches, so that it does not exert any undesirable forces on the free fiber lunar sections that possibly could lead to incorrect delays or broken rags.

Um für Wartungsarbeiten auch von oben an die einzelnen Spinnstellen gelangen zu können, ist das Ausführungsbeispiel nach Anspruch 4 vorgesehen.In order to be able to access the individual spinning positions from above for maintenance work, the exemplary embodiment according to claim 4 is provided.

Das Ausführungsbeispiel nach Anspruch 5 hat den Vorteil, daß der Bereich der freien Faserluntenabschnitte, in dem durch aus dem Faserverband herausgelöste Fasern relativ viel Flug entsteht, nahezu vollständig vom Inneren der Spinnmaschine abgeschirmt ist, so daß der Innenbereich der Maschine in vereinfachter Weise saubergehalten werden kann.The embodiment according to claim 5 has the advantage that the area of the free fiber sliver sections, in which there is a relatively large amount of flight due to fibers released from the fiber structure, is almost completely shielded from the inside of the spinning machine, so that the interior of the machine can be kept clean in a simplified manner .

Dabei läßt sich auch die bei Luntenbrüchen erforderliche Luntenabsaugung verbessern, da die Absaugöffnungen dichter an den Lieferzylindern angeordnet werden können.It can also improve the roving extraction required in the event of rupture of rags, since the extraction openings can be arranged closer to the delivery cylinders.

Lufttechnisch und konstruktiv vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 6, 7 und 8 beschrieben.Advantages of the invention in terms of ventilation and construction are described in claims 6, 7 and 8.

Eine besonders einfache und stabile Anordnung der Tischplatte für die erfindungsgemäße Spinnmaschine ist im Anspruch 9 erläutert.A particularly simple and stable arrangement of the table top for the spinning machine according to the invention is explained in claim 9.

Ein anderes praktisches Ausführungsbeispiel der Erfindung ist im Patentanspruch 10 beschrieben.Another practical embodiment of the invention is described in claim 10.

Bei diesem Ausführungsbeispiel der Erfindung ermöglicht es der freie Überwachungsbereich, jede übliche Luntenbruchüberwachungsvorrichtung, wie sie auch bei herkömmlichen Spinnmaschinen oder Flyern verwendet wird, einzusetzen.In this embodiment of the invention, it enables the free monitoring area to use any conventional sliver break monitoring device, as is also used in conventional spinning machines or flyers.

Dabei kann insbesondere, wie im Anspruch 11 beschrieben, eine Lichtschranke vorgesehen sein, die bei einem bestimmten Durchhang der Lunte anspricht und einen Luntenbruch anzeigt.In particular, as described in claim 11, a light barrier can be provided which responds to the fuse with a certain sag and indicates a fuse break.

Weitere vorteilhafte Ausgestaltungen des Ausführungsbeispiels nach Anspruch 10 sind in den Ansprüchen 12 und 13 beschrieben.Further advantageous embodiments of the embodiment according to claim 10 are described in claims 12 and 13.

Die Erfindung wird im folgenden beispielsweise anhand der Zeichnung näher erläutert; in dieser zeigt:

Fig. 1
eine rein schematische, teilweise geschnittene Seitenansicht einer Spinnmaschine, insbesondere eines Flyers, und
Fig. 2
eine Seitenansicht entsprechend Fig. 1 eines abgewandelten Flyers.
The invention is explained in more detail below, for example with reference to the drawing; in this shows:
Fig. 1
a purely schematic, partially sectioned side view of a spinning machine, in particular a flyer, and
Fig. 2
a side view corresponding to FIG. 1 of a modified flyer.

In den beiden Figuren der Zeichnung sind einander entsprechende Bauteile mit gleichen Bezugszeichen bezeichnet.Corresponding components in the two figures of the drawing are identified by the same reference numerals.

Nach Fig. 1 weist eine Vorspinnmaschine oder Flyer einen schematisch dargestellten Maschinenrahmen 23 mit einem Fußgestell 25 und einer schematisch dargestellten Tragsäulenanordnung 26 auf. Am Fußgestell 25 des Maschinenrahmens 23 ist eine Spulenbank 24 angeordnet, die zwei, sich über die Länge der Maschine erstreckende, quer zur Maschinenlängsrichtung nebeneinanderliegende Reihen von Spulen 27 trägt.1, a roving machine or flyer has a schematically illustrated machine frame 23 with a base frame 25 and a schematically illustrated support column arrangement 26. A spool bank 24 is arranged on the base frame 25 of the machine frame 23 and carries two rows of spools 27, which extend over the length of the machine and are adjacent to one another transversely to the machine longitudinal direction.

Entsprechend den Spulen 27 sind zwei Reihen von Flyerflügeln 28 an einer Flügelbank 29 angeordnet, die an der Tragsäulenanordnung 26 befestigt ist. Auf der Bedienungsseite der Vorspinnmaschine ist ein Schutzschirm 22 an der Flügelbank 29 angeordnet. Dabei ist der Schutzschirm 22 vorteilhafterweise so ausgebildet bzw. so an der Spinnmaschine angeordnet, daß er wegklappbar ist, um den freien Zugang zu den einzelnen von den Spulen 27 und den Flyerflügeln 28 gebildeten Spinnstellen zu ermöglichen.Corresponding to the coils 27, two rows of flyer wings 28 are arranged on a wing bench 29, which are arranged on the support column arrangement 26 is attached. A protective screen 22 is arranged on the wing bench 29 on the operating side of the roving machine. The protective screen 22 is advantageously designed or arranged on the spinning machine in such a way that it can be folded away in order to allow free access to the individual spinning positions formed by the spools 27 and the flyer wings 28.

Auf der Tragsäulenanordnung 26 sind Streckwerke 11 - von denen nur eins dargestellt ist - angeordnet, dem Faserbänder, z.B. Streckenbänder 30 zugeführt sind. Wie in Fig.1 gezeigt, ist im Bereich der Auslaufseite der Streckwerke 11, also im Bereich von Lieferzylindern 17 der Streckwerke 11 ein Luftabsaugkanal 19 auf der Tragsäulenanordnung 26 angebracht. Der Luftabsaugkanal 19, der z.B. als Hohlprofil ausgebildet sein kann, weist in seiner Oberwand 20 Luntenabsaugöffnungen 18 auf, um im Falle eines Luntenbruchs die vom Streckwerk 11 weitergelieferte Faserlunte bzw. das Faserbändchen abzusaugen, damit die von den Streckwerken 11 weitergelieferten Bändchen oder Lunten nicht zu weiteren Störungen des Spinnbetriebs führen können.On the support column arrangement 26 there are arranged drafting systems 11 - only one of which is shown - to which fiber slivers, e.g. Track belts 30 are supplied. As shown in FIG. 1, in the area of the outlet side of the drafting systems 11, that is to say in the area of delivery cylinders 17 of the drafting systems 11, an air suction duct 19 is attached to the support column arrangement 26. The air extraction duct 19, which e.g. can be designed as a hollow profile, has 20 sliver suction openings 18 in its upper wall, in order to suck off the fiber sliver or the fiber ribbon supplied by the drafting device 11 in the event of a rupture of the sliver, so that the ribbon or sliver supplied by the drafting devices 11 cannot lead to further disruptions to the spinning operation .

An den oberen Enden von Flyerflügelaufsätzen 31, 32 sind als Umlenk- und Führungskörper für die Faserlunten 12 Drallkörper 10 vorgesehen, um die von den Lieferzylindern 17 der Streckwerke 11 kommenden Faserlunten 12 umzulenken und durch die Flyerflügelaufsätze 31, 32 zu den Flyerflügeln 28 der entsprechenden Spinnstellen zu führen.At the upper ends of flyer wing attachments 31, 32, swirl bodies 10 are provided as deflection and guide bodies for the fiber lunches, in order to deflect the fiber lunches 12 coming from the delivery cylinders 17 of the drafting devices 11 and through the flyer wing attachments 31, 32 to the flyer wings 28 of the corresponding spinning positions respectively.

Die Flyerflügelaufsätze 32 der inneren Reihe von Flyerflügeln sind dabei länger ausgebildet als die Flyerflügelaufsätze der äußeren Flyerflügelreihe, so daß die Drallkörper 10 im wesentlichen in einer Ebene angeordnet sind, die mit einer durch die Berührungslinien der einzelnen Streckwerkzylinder gegebenen Ebene zusammenfällt. Hierdurch wird erreicht, daß die freien Faserluntenabschnitte 12 aller von den Streckwerken 11 gelieferten Faserlunten in einer Ebene liegen, und zwar unabhängig davon, ob die Faserlunten zu Spinnstellen der vorderen oder der hinteren Spinnstellenreihe geführt werden.The flyer wing attachments 32 of the inner row of flyer wings are longer than the flyer wing attachments of the outer flyer wing row, so that the swirl bodies 10 are arranged essentially in a plane which coincides with a plane given by the lines of contact of the individual drafting cylinders. This ensures that the free fiber sliver sections 12 of all the fiber slivers supplied by the drafting units 11 lie in one plane, regardless of whether the fiber slabs are guided to spinning positions of the front or rear row of spinning positions.

An dem Hohlprofil des Luftabsaugkanals 19 ist eine Tischplatte 13 angelenkt, die mit ihrer Vorderkante 21 im Bereich des Schutzschirms 22 auf der Flügelbank 29 aufliegt. Dabei kann zwischen der Flügelbank 29 und der Vorderkante 21 der Tischplatte 13 eine nicht dargestellte Abdichtung vorgesehen sein.A table top 13 is articulated to the hollow profile of the air extraction duct 19 and its front edge 21 rests on the wing bench 29 in the area of the protective screen 22. A seal, not shown, can be provided between the wing bench 29 and the front edge 21 of the table top 13.

Die Tischplatte 13 weist Durchlaßöffnungen 33 auf, durch die die Flyerflügelaufsätze 31, 32 mit ihren Drallkörpern 10 nach oben hindurchragen können.The table top 13 has passage openings 33 through which the flyer wing attachments 31, 32 with their swirl bodies 10 can protrude upwards.

Die Tischplatte 13, die parallel zu der durch die freien Faserluntenabschnitte 12 gegebenen Ebene angeordnet ist, ist vorzugsweise mit der Oberwand 20 des Luftabsaugkanals 19 ausgerichtet, so daß sich eine im wesentlichen geschlossene ebene Oberfläche ergibt, die sich vom Bereich der Lieferzylinder 17 bis zum bedienungsseitigen Rand der Flügelbank 29 erstreckt.The table top 13, which is arranged parallel to the plane given by the free fiber sliver sections 12, is preferably aligned with the top wall 20 of the air extraction duct 19, so that there is a substantially closed flat surface, which extends from the area of the delivery cylinders 17 to the operator side Edge of the wing bench 29 extends.

Zum Sauberblasen der Tischplatte 13 ist als Blasvorrichtung ein Wanderbläser 14 vorgesehen, der an einem in nicht dargestellter Weise mit dem Maschinenrahmen verbundenen Schienensystem 35 verfahrbar angeordnet ist. Der Wanderbläser 14 ist über eine schematisch dargestellte, flexible Druckluftleitung 36 mit einer nicht dargestellten Druckluftquelle verbunden. Ein Bläserarm 15 des Wanderbläsers erstreckt sich bis in den Bereich der Tischplatte 13, wo eine Blasdüse 16 so angeordnet ist, daß die Tischplatte 13 jeweils in Richtung der freien Faserluntenabschnitte 12 sauberblasbar ist.For blowing the table top 13 clean, a traveling blower 14 is provided as a blowing device, which is arranged to be movable on a rail system 35 which is connected to the machine frame in a manner not shown. The traveling blower 14 is connected via a schematically illustrated, flexible compressed air line 36 to a compressed air source, not shown. A blower arm 15 of the traveling blower extends into the region of the table top 13, where a blowing nozzle 16 is arranged such that the table top 13 can be blown clean in the direction of the free fiber sliver sections 12.

Wahlweise kann eine Streckwerk-Absaugdüse 37 mittels eines entsprechenden Saugarms 38 am Wanderbläser 14 angeordnet sein. Dementsprechend ist der Wanderbläser 14 in nicht dargestellter Weise mit einer Unterdruckquelle verbunden.Optionally, a drafting device suction nozzle 37 can be arranged on the traveling blower 14 by means of a corresponding suction arm 38. Accordingly, the traveling blower 14 is connected in a manner not shown to a vacuum source.

Um die beschriebene Vorspinnmaschine während des Spinnbetriebs sauberzuhalten und Flugansammlungen weitgehend zu vermeiden, fährt der Wanderbläser 14 nach Bedarf oder periodisch die Vorspinnmaschine ab, wobei die Tischplatte 13 durch die Blasdüse 16 saubergeblasen wird. Gleichzeitig werden aus den Faserbändern herausgelöste Fasern im Bereich der Streckwerke 11 durch die Streckwerk-Absaugdüse 37 abgesaugt.In order to keep the described roving machine clean during the spinning operation and to largely avoid flight accumulations, the traveling blower 14 moves the roving machine 14 as required or periodically, the table top 13 being blown clean by the blowing nozzle 16. At the same time, fibers detached from the fiber tapes are sucked off in the area of the drafting systems 11 by the drafting system suction nozzle 37.

Auf diese Weise läßt sich eine Verflugung der Vorspinnmaschine kostengünstig und energiesparend verhindern, wobei die spezielle Ausrichtung der Blasdüse 16 sowie der parallel zu den freien Faserluntenabschnitten 12 angeordneten Tischplatte 13 eine Störung des Spinnbetriebes weitgehend vermeiden, da die freien Faserluntenabschnitte 12 von dem Reinigungsluftstrom in ihrer Längsrichtung beaufschlagt werden, so daß praktisch keine Kräfte auf sie einwirken, die zu Luntenbrüchen führen könnten.In this way, flying of the roving machine can be prevented in a cost-effective and energy-saving manner, the special orientation of the blowing nozzle 16 and the table top 13 arranged parallel to the free fiber sliver sections 12 largely avoiding a disruption of the spinning operation, since the free fiber sliver sections 12 depend on the cleaning air flow in their longitudinal direction be acted on, so that practically no forces act on them, which could lead to match breaks.

Anstelle einer Tischplatte 13, die sich von dem Hohlprofil des Luftabsaugkanals 19 zur bedienungsseitigen Vorderkante der Flügelbank 29 erstreckt, kann eine Tischplatte vorgesehen sein, die auch oberhalb des Luftabsaugkanals 19 angeordnet ist. Hierbei müssen dann in der Tischplatte entsprechende Luntenabsaugöffnungen vorgesehen werden.Instead of a table top 13, which extends from the hollow profile of the air suction duct 19 to the operator-side front edge of the wing bench 29, a table top can also be provided, which is also arranged above the air suction duct 19. Appropriate sliver suction openings must then be provided in the table top.

Die Vorspinnmaschine oder der Flyer nach Fig.2 unterscheidet sich vom Flyer nach Fig.1 im wesentlichen nur dadurch, daß die Tischplatte 13 mit ihrer den Streckwerken 11 zugewandten Längskante 34 mit Abstand zu den Lieferzylindern 17 angeordnet ist, so daß zwischen der Längskante 34 und den Lieferzylindern 17 ein sich bis unterhalb der Ebene der Tischplatte 13 erstreckender Überwachungsbereich 40 vorgesehen ist.The pre-spinning machine or the flyer according to FIG. 2 differs from the flyer according to FIG. 1 essentially only in that the table top 13 with its longitudinal edge 34 facing the drafting units 11 is arranged at a distance from the delivery cylinders 17 is, so that between the longitudinal edge 34 and the delivery cylinders 17, a monitoring area 40 extending to below the level of the table top 13 is provided.

Entsprechend Fig. 2 ist auf der Tragsäulenanordnung 26 ein Haltebügel 43 vorgesehen, an dessen oberem Ende die Tischplatte 13 um eine parallel zur Maschinenlängsrichtung verlaufende Schwenkachse schwenkbar angeordnet ist. Der Haltebügel 43 begrenzt dabei den Überwachungsbereich 40, in welchem eine sich über den Spinnstellenbereich des Flyers erstreckende Lichtschranke 41 angeordnet ist, um Luntenbrüche zu erfassen.2, a support bracket 43 is provided on the support column arrangement 26, at the upper end of which the table top 13 is arranged to be pivotable about a pivot axis running parallel to the longitudinal direction of the machine. The holding bracket 43 delimits the monitoring area 40, in which a light barrier 41 is arranged, which extends over the spinning area of the flyer, in order to detect broken rags.

Jedem Streckwerk 11 ist ein Luntenabsaugrohr 42 zugeordnet, das in nicht dargestellter Weise an einen Luftabsaugkanal angeschlossen ist. Das Luntenabsaugrohr 42 dient dazu, im Falle eines Luntenbruchs die gebrochene Faserlunte abzuziehen, die bis zum Abstellen der Vorspinnmaschine noch weitergeliefert wurde.Each drafting system 11 is assigned a sliver suction tube 42, which is connected to an air suction channel in a manner not shown. The sliver suction tube 42 serves to pull off the broken fiber sliver in the event of a sliver break, which was still supplied until the roving machine was switched off.

Oberhalb der freien Faserluntenabschnitte 12 ist wiederum ein Wanderbläser 14 angeordnet, der einen eine abgebogene Blasdüse 16 aufweisenden Bläserarm trägt. Die Blasdüse 16 ist dabei so mit der Längskante 34 der Tischplatte 13 ausgerichtet, daß der die Blasdüse 16 verlassende Reinigungsluftstrom in Transportrichtung der Faserlunten 12 gesehen hinter der Längskante 34 die Ebene der Tischplatte 13 und damit die Oberfläche der Tischplatte 13 erreicht, so daß in den Überwachungsbereich 40 keine Luft eingeblasen wird.A traveling blower 14, which carries a blower arm having a bent blower nozzle 16, is in turn arranged above the free fiber sliver sections 12. The blowing nozzle 16 is aligned with the longitudinal edge 34 of the table top 13 so that the cleaning air stream leaving the blowing nozzle 16 seen in the transport direction of the fiber lunches 12 behind the longitudinal edge 34 reaches the level of the table top 13 and thus the surface of the table top 13, so that in the Monitoring area 40 no air is blown.

Die anhand von Fig. 2 beschriebene Vorspinnmaschine wird während des Spinnbetriebes in gleicher Weise saubergehalten, wie die Vorsprinnmaschine nach Fig.1.The pre-spinning machine described with reference to FIG. 2 is kept clean during the spinning operation in the same way as the pre-spinning machine according to FIG. 1.

Tritt ein Luntenbruch auf, so bildet sich zunächst ein Durchhang der gebrochenen Lunte, der von der Lichtschranke 41 erfaßt wird, woraufhin die gesamte Vorspinnmaschine abgeschaltet wird.If a fuse break occurs, a sag first forms the broken fuse which is detected by the light barrier 41, whereupon the entire roving machine is switched off.

Bis zum Abschalten der Vorspinnmaschine weitergeliefertes Fasermaterial wird an dem Streckwerk 11, an dem ein Luntenbruch aufgetreten ist, mittels des dort vorgesehenen Luntenabsaugrohrs 42 abgesaugt. Anstelle eines Luntenabsaugrohrs 42 kann auch eine beliebige andere Möglichkeit zur Beseitigung von bei Luntenbrüchen anfallendem Fasermaterial vorgesehen sein.Until the pre-spinning machine is switched off, fiber material which is supplied is sucked off on the drafting system 11, on which a sliver breakage has occurred, by means of the sliver suction tube 42 provided there. Instead of a sliver suction tube 42, any other possibility can also be provided for the removal of fiber material resulting from sliver breaks.
