Eine Unterdruckquelle sorgt für die Absaug-Luftströmung S.In order to be able to suction several threads (11) simultaneously and with the same intensity, a pneumatic piston (9) provided with a suction nozzle (12) is pushed against the threads (11) until all threads (11) can be suctioned off as a common bundle. To move the piston (9), an annular surface (17) of the piston (9) is charged with compressed air via the valve (20 or 21) and via the channels (23, 24, 25 and 16). A vacuum source ensures the suction air flow S.

Description

Die Erfindung bezieht sich auf eine Fadenabsaugvorrichtung mit einer zum Fadenlauf im wesentlichen senkrecht angeordneten Fadenabsaugdüse.The invention relates to a thread suction device with a thread suction nozzle arranged substantially perpendicular to the thread path.

Solche Fadenabsaugvorrichtungen werden hauptsächlich in Verfahren zum Bearbeiten von Endlosfilamenten verwendet, z.B. bei Streck-Spul- oder Spinn-Streck-Spul-Verfahren.Such thread suction devices are mainly used in processes for processing continuous filaments, e.g. in draw-winder or spin-draw-wrap processes.

Frühere Verfahren behandelten pro Spinnstelle jeweils nur einen Faden, während in der näheren Vergangenheit die mehrfädige Bearbeitung pro Spinnstelle angewendet wurde und mindestens in der Zukunft aus Rationalisierungsgründen auch weiterhin angewendet wird.Earlier processes only dealt with one thread per spinning station, whereas in the recent past multi-thread processing was used per spinning station and will continue to be used at least in the future for reasons of rationalization.

Absaugvorrichtungen arbeiten in der Regel mit Fadenüberwachungselementen zusammen, um bei im Fadenlauf an nachfolgenden Verarbeitungsstellen auftretenden Störungen die Fadenzufuhr an diesen Stellen so rasch als möglich zu unterbrechen.Suction devices generally work together with thread monitoring elements in order to interrupt the thread supply at these points as quickly as possible in the event of faults occurring in the thread run at subsequent processing points.

Bei mehrfädigen Anordnungen wurde dabei pro Faden je eine separate Absaugvorrichtung verwendet, was aufwendig war.In the case of multi-thread arrangements, there was one thread per thread used a separate suction device, which was expensive.

Die Erfindung hat deshalb zur Aufgabe, diesen Nachteil zu beheben und löst sie mit den im kennzeichnenden Teil des ersten Anspruches aufgeführten Merkmalen.The object of the invention is therefore to remedy this disadvantage and to solve it with the features listed in the characterizing part of the first claim.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass sämtliche Fäden gleichzeitig und gleichmässig intensiv abgesaugt werden, sowie dass die Vorrichtung platz- und betriebsmittelsparend (z.B. Luft) verwendet werden kann.The advantages achieved by the invention are essentially to be seen in the fact that all threads are sucked off simultaneously and uniformly intensively, and that the device can be used in a space and resource-saving manner (e.g. air).

Die Erfindung kann auch mit Vorteil für einzelne Fäden verwendet werden, falls an der Absaugstelle Schwingungen im Faden nicht zu vermeiden sind.The invention can also be used with advantage for individual threads if vibrations in the thread cannot be avoided at the suction point.

Im folgenden wird die Erfindung von lediglich zwei Ausführungswege darstellenden Zeichnungen näher erläutert.In the following, the invention is explained in more detail by drawings showing only two possible embodiments.

Es zeigt:

  • Fig. 2 einen Grundriss der Vorrichtung von Fig. 1
  • Fig. 3 einen Längsschnitt durch eine Variante der erfindungsgemässen Fadenabsaugvorrichtung, halbschematisch dargestellt
  • Fig. 4 einen Grundriss der Vorrichtung von Fig. 3.
It shows:
  • Fig. 1 shows a longitudinal section through a thread suction device according to the invention, shown semi-schematically
  • FIG. 2 is a plan view of the device of FIG. 1
  • Fig. 3 shows a longitudinal section through a variant of the thread suction device according to the invention, shown semi-schematically
  • F ig. 4 shows a plan view of the device from FIG. 3.

Eine Fadenabsaugvorrichtung umfasst einen Kopfteil 1 und einen Diffusorteil 2. Der Kopfteil 1 ist in einer Bohrung 3 eines Maschinenrahmens 4 geführt und liegt mit einem dazugehörigen Flansch 5 am Maschinenrahmen 4 an. Zwei Schrauben 6 befestigen den Kopfteil 1 am Maschinenrahmen 4. Der Diffusorteil 2 wird mittels Gewinde 7 in den Maschinenrahmen 4 eingeschraubt. An der Stelle, an welcher der Diffusorteil 2 am Kopfteil 1 anliegt, dichtet ein O-Ring 8 den Luftdurchlass quer zur Luftströmungsrichtung S ab. Zum Kopfteil 1 gehört im weiteren ein sogenannt einseitig beaufschlagbarer, gegen Verdrehung gesicherter, Pneumatikkolben 9 mit einem Strömungskanal 10 zur Führung der Luftströmung S.A thread suction device comprises a head part 1 and a diffuser part 2. The head part 1 is guided in a bore 3 of a machine frame 4 and bears against the machine frame 4 with an associated flange 5. Two screws 6 fasten the head part 1 to the machine frame 4. The diffuser part 2 is screwed into the machine frame 4 by means of thread 7. At the point where the diffuser part 2 rests on the head part 1, an O-ring 8 seals the air passage transversely to the air flow direction S. The head part 1 also includes a so-called one-sided pressurized, secured against rotation, pneumatic piston 9 with a flow channel 10 for guiding the air flow S.

An der gegen eine Anzahl Fäden gerichteten Mündung des Strömungskanales 10 ist ein Mündungsteil 12 aus Keramikmaterial im Kolben 9 fest eingelassen. Im weiteren bildet ein hohlzylindrischer Fortsatz 13 des Kolbens 9 die dem Diffusorteil 2 entgegengerichtete Mündung des Kanales 10.At the mouth of the flow channel 10 directed against a number of threads, a mouth part 12 made of ceramic material is firmly embedded in the piston 9. Furthermore, a hollow cylindrical extension 13 of the piston 9 forms the opening of the channel 10 opposite the diffuser part 2.

Zum Kopfteil 1 gehört im weiteren ein stationärer Zylinderteil 14 mit einem mit dem Zylinderteil 14 fest verbundenen Zylinderdeckel 15.The head part 1 further includes a stationary cylinder part 14 with a cylinder cover 15 firmly connected to the cylinder part 14.

Der vorgenannte Flansch 5 ist ebenfalls ein Bestandteil dieses Zylinderteiles 14.The aforementioned flange 5 is also a component of this cylinder part 14.

Der Kolben 9 ist im Zylinderteil 14 sowie im Zylinderdeckel 15 verschiebbar geführt. Die für das Bewegen des Kolbens 9 benötigte Druckluft wird durch eine im Zwischenteil 14 vorgesehene Einlassöffnung 16 geführt. Die Druckluft beaufschlagt primär eine am Kolben 9 vorgesehene ringförmige Fläche 17, wobei anschliessend nach Abheben des Kolbens die sich aus der Differenz der Durchmesser D-d ergebende Ringfläche beaufschlagt wird. Zur Rückstellung des Kolbens 9 in die in Fig. 1 gezeigte Ausgangslage des Kolbens 9 dient eine auf Druck beanspruchte Schraubenfeder 18.The piston 9 is slidably guided in the cylinder part 14 and in the cylinder cover 15. The compressed air required for moving the piston 9 is by a Intermediate part 14 provided inlet opening 16 out. The compressed air primarily acts on an annular surface 17 provided on the piston 9, and after lifting off the piston the annular surface resulting from the difference in the diameter Dd is then acted upon. A coil spring 18, which is subjected to pressure, serves to return the piston 9 to the initial position of the piston 9 shown in FIG. 1.

Die Druckluft wird ab einer Druckluftquelle 19 über ein Zwei/Zwei-Wegventil 20 oder über ein Drei/Zwei-Wegventil 21 (die Varianten werden später erklärt) sowie via ein Anschlussteil 22 durch Kanäle 23 und 24 in einen Verteilraum 25 und anschliessend in die Kanäle 16 geführt.The compressed air is supplied from a compressed air source 19 via a two / two-way valve 20 or a three / two-way valve 21 (the variants will be explained later) and via a connecting part 22 through channels 23 and 24 into a distribution space 25 and then into the channels 16 out.

Die für das Absaugen der Fäden 11 benötigte Luftströmung S kann entweder durch eine nach dem Diffusorteil 2 verwendete, nicht gezeigte, Unterdruckquelle oder dadurch erzeugt werden, dass im Diffusor nicht gezeigte Bohrungen angebracht werden, welche mit dem Verteilraum 25 derart in Verbindung stehen, dass beim Einströmen der Druckluft durch die Kanäle (nicht gezeigt) in den Diffusorteil ein Unterdruck im Kanal 10 erzeugt wird. In einem solchen Fall wird das Ventil 20 verwendet, da damit die für die Rückwärtsbewegung des Kolbens notwendige Entlüftung durch die nicht gezeigten Kanäle geschehen kann.The air flow S required for the suction of the threads 11 can either be generated by a vacuum source, not shown, used after the diffuser part 2, or by drilling bores, not shown, in the diffuser, which are connected to the distribution space 25 in such a way that when Inflow of the compressed air through the channels (not shown) into the diffuser part creates a negative pressure in the channel 10. In such a case, the valve 20 is used, since the ventilation necessary for the backward movement of the piston can take place through the channels, not shown.

Im anderen Fall, d.h. bei Verwendung einer Unterdruckquelle, fehlen diese nicht gezeigten Kanäle, so dass die vorgenannte Entlüftung über das Ventil 21 geschehen muss.In the other case, i.e. when using a vacuum source, these channels, not shown, are missing, so that the aforementioned venting must take place via the valve 21.

Als Diffusorteile können auch andere handelsübliche Venturidüsen verwendet werden und der Kanal 10 diesen Düsen angepasst werden.Other commercially available Venturi nozzles can also be used as diffuser parts and the channel 10 can be adapted to these nozzles.

Im Betrieb wird für das Absaugen der Fäden 11 im einen Falle das Ventil 20 für das Durchströmen der Luft von P nach A in die entsprechende Stellung gebracht, so dass einerseits der Kolben 9 einen Hub bis zum Anschlagen eines O-Ringes 26 am Deckel 15 durchführt und dabei der Mündungsteil 12 die Fäden 11 zu einem einzigen Faden gebündelt zusammenschiebt, und anderseits die Luftströmung S auf die erwähnte Art erzeugt wird. Nachdem eine in Fadenlaufrichtung F nachgeschaltete Schneidvorrichtung (nicht gezeigt) die Fäden 11 zerschnitten hat, werden diese gemeinsam und praktisch mit gleicher Intensität abgesaugt.In operation, the valve 20 for the passage of air from P to A is brought into the corresponding position for the suction of the threads 11 so that on the one hand the piston 9 performs a stroke until an O-ring 26 strikes the cover 15 and the mouth part 12 pushes the threads 11 together into a single thread, and on the other hand the air flow S is generated in the manner mentioned. After a cutting device (not shown) connected downstream in the thread running direction F has cut the threads 11, these are sucked off together and practically with the same intensity.

Im anderen Falle wird gleichzeitig mit dem Verschieben des Ventiles 21 für den Durchlass der Druckluft von P nach A die genannte Unterdruckquelle in Funktion gesetzt. Zur Lenkung der Luftströmung vor dem Eintritt in den Mündungsteil 12.dient ein zum Kolben 9 gehörender, mit Schlitzen 27 versehener hohlzylindrischer Fortsatz 28.In the other case, the mentioned vacuum source is activated simultaneously with the displacement of the valve 21 for the passage of the compressed air from P to A. A hollow cylindrical extension 28, which is part of the piston 9 and is provided with slots 27, is used to direct the air flow before it enters the mouth part 12.

Im weiteren sind, um zu verhindern, dass Leckluft entweichen kann, Dichtungen 29, 30 und 31 vorgesehen.In addition, seals 29, 30 and 31 are provided to prevent leakage air from escaping.

Letztlich ist der Diffusorteil mittels eines Schlauches 32 direkt oder via Unterdruckquelle mit einem Aufnahmebehälter (nicht gezeigt) verbunden.Ultimately, the diffuser part is connected directly to a receptacle (not shown) by means of a hose 32 or via a vacuum source.

In der mit den Figuren 3 und 4 gezeigten Variante sind Elemente der mit den Figuren 1 und 2 gezeigten Fadenabsaugvorrichtung mit gleichen Bezugszeichen versehen.In the variant shown with Figures 3 and 4 are Elements of the thread suction device shown in FIGS. 1 and 2 are provided with the same reference symbols.

In dieser Variante ist ein Kopfteil 100 in der Bohrung 3 geführt und liegt mittels eines dazugehörigen Flansches 101 am Maschinenrahmen 4 an und ist durch zwei Schrauben 102 an diesem befestigt.In this variant, a head part 100 is guided in the bore 3 and is in contact with the machine frame 4 by means of an associated flange 101 and is fastened to it by two screws 102.

Der Kopfteil 100 umfasst ausserdem einen stationären Zylinderteil 103 mit einem daran befestigten Zylinderdeckel 104 sowie einen gegen Verdrehung gesicherten Pneumakolben 105, welcher auf einem zum Zylinderteil 103 gehörenden koaxialen Dorn 106 verschiebbar geführt ist. Der Kolben 105 ist an einer Ringfläche 107 mit Druckluft für das Verschieben gegen die Kraft einer Feder 108 beaufschlagbar.The head part 100 also comprises a stationary cylinder part 103 with a cylinder cover 104 attached to it, and a pneumatic piston 105 secured against rotation, which is displaceably guided on a coaxial mandrel 106 belonging to the cylinder part 103. The piston 105 can be acted upon on an annular surface 107 with compressed air for displacement against the force of a spring 108.

Der Kolbenhub ist durch die Anschläge 109 und 110 begrenzt.The piston stroke is limited by the stops 109 and 110.

Zum Vermeiden, dass die für das Verschieben des Kolbens benötigte Druckluft als Leckluft einerseits in den Raum in dem sich die Feder befindet und anderseits in die Atmosphäre entweichen kann, sind, wie in Fig. 3 gezeigt, entsprechende O-Ring-Dichtungen 111 und 112 vorgesehen.To prevent the compressed air required for moving the piston as leakage air into the space in which the spring is located on the one hand and on the other hand can escape into the atmosphere, corresponding O-ring seals 111 and 112 are shown in FIG. 3 intended.

An einem nach aussen ragenden ebenfalls hohlzylindrischen Fortsatz 113 des Pneumatikkolbens 105 sind Aussparungen 114 für die Fäden 11 vorgesehen. Ebenso ist im Dorn 106 ein Kanal 115 mit einer Mündung 116 für den Durchlass der Luftströmung S vorgesehen.Recesses 114 for the threads 11 are provided on an outwardly projecting, likewise hollow cylindrical extension 113 of the pneumatic piston 105. A channel 115 with an opening 116 for the passage of the air flow S is likewise provided in the mandrel 106.

Die Beschickung des Kolbens 105 mit Druckluft geschieht wie in Fig. 3 gezeigt durch die Kanäle 23, 117 und 118.The piston 105 is supplied with compressed air as shown in FIG. 3 through channels 23, 117 and 118.

Im Betrieb wird nun wie bereits früher erwähnt je nach Variante zur Erzeugung der Luftströmung S das Ventil 20 oder 21 verwendet. In beiden Fällen wird die Fläche 107 über die Kanäle 23, 117 und 118 mit Druckluft beschickt und der Kolben 105 gegen die Kraft der Feder 108 bis zur Begrenzung des Hubes durch den Anschlag 110 verschoben. Durch diese Bewegung verschiebt sich zwangsläufig auch der Fortsatz 113 und damit ein am Fortsatz vorgesehener Mitnehmer 119. Mittels diesem Mitnehmer werden die Fäden 11 bis zur Anlage aller Fäden an der Mündung 116 zusammengeschoben, um, nachdem eine in Fadenlaufrichtung ausgeschaltete Fadenschneidvorrichtung (nicht gezeigt) die Fäden zerschnitten hat, gemeinsam und mit praktisch für alle Fäden gleicher Intensität abgesaugt zu werden.In operation, depending on the variant, the valve 20 or 21 is now used to generate the air flow S, as already mentioned earlier. In both cases, the surface 107 is supplied with compressed air via the channels 23, 117 and 118 and the piston 105 is pushed against the force of the spring 108 until the stroke 110 is limited by the stop 110. This movement inevitably also shifts the extension 113 and thus a driver 119 provided on the extension. By means of this driver, the threads 11 are pushed together until all the threads abut the mouth 116, after a thread cutting device (not shown) that is switched off in the thread running direction Cut threads to be sucked together and with practically the same intensity for all threads.

Nach dem Zurückstellen der Ventile 21 oder 20 in die in Figur 3 gezeigte Position werden die Kanäle 23, 117 und 118 wieder entlüftet, so dass der Kolben 105 wieder in die in Fig. 3 gezeigte Ausgangsstellung zurückverschoben wird.After resetting the valves 21 or 20 to the position shown in FIG. 3, the channels 23, 117 and 118 are vented again, so that the piston 105 is pushed back into the starting position shown in FIG. 3.

Die Luft im Raum, in welcher sich die Feder 18, respektive 108, befindet entweicht beim Kolbenhub durch eine Oeffnung (nicht gezeigt) in die Atmosphäre.The air in the room in which the spring 18 or 108 is located escapes through an opening (not shown) into the atmosphere during the piston stroke.
