Abstract

The invention relates to a method and a device for separating the roving between the press fingers 5 on the fliers 4 of a slubbing machine, equipped with a drawing unit 2, and the full roving bobbins 10. For this, the slubbing machine is stopped in a position or runs down in a position in which the press fingers 5 are close underneath the upper reversal point of the last turn layer on the bobbin 10, whereupon the non-rotating or running-down bobbins 10 or flyers 4 are moved axially relative to one another in such a way that the press fingers 5 are guided close under the reversal point of the first turn layer, after which the bobbins 10 are subsequently moved at least half a revolution forwards. According to the nature of the material to be processed, the rovings 12 are loosened between the drawing unit 2 and the press fingers 5, and for the concluding separating operation the non-rotating bobbins 10 and fliers 4 are moved axially relative to one another in such a way that the press fingers are guided downwards. …<IMAGE>…

Description

Die Erfindung bezieht sich auf ein Verfahren und Vorrichtung zum Trennen des Vorgarns zwischen den Preßfingern an den Flügeln einer mit einem Streckwerk versehenen Vorspinnmaschine und den vollen Vorgarnspulen.The invention relates to a method and device for separating the roving between the pressing fingers on the wings of a roving machine provided with a drafting machine and the full roving bobbins.

An einem Flyer soll beim Abziehen von Vorgarnspulen das Vorgarn so getrennt werden, daß an der Preßfingerplatte nur ein kurzes, freihängendes Vorgarnstück verbleibt, während das andere Vorgarnende auf der Spule möglichst so abgelegt werden soll, daß es beim nachfolgenden in der Regel hängenden Weitertransport der Spulen nicht abfällt.When pulling off roving bobbins on a flyer, the roving is to be separated so that only a short, freely hanging roving piece remains on the press finger plate, while the other roving end is to be placed on the spool as far as possible so that it is generally suspended in the subsequent further transport of the bobbins does not fall off.

Langstapeliges Material, wie beispielsweise Wolle, synthetische Fasern mit Wolle in entsprechender Stapellänge, setzen hierbei diesem gewünschten Trennen erheblichen Widerstand entgegen, da das Vorgarn durch Anlage am Preßfinger und an der Spule unter Druck steht und eine hohe Haftreibung der Fasern untereinander bewirkt wird. Außerdem ist nicht gewährleistet, daß das Ende der Wicklung auf dem oberen Windungskegel liegt.Long-staple material, such as wool, synthetic fibers with wool in the appropriate pile length, provide considerable resistance to this desired separation, since the roving is under pressure due to contact with the press finger and the spool and a high static friction of the fibers is brought about. In addition, there is no guarantee that the end of the winding will lie on the upper winding cone.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, beim Abziehen von Vorgarnspulen am Flyer das Vorgarn, d.h. die Lunte, so zu trennen, daß das Luntenende auf dem oberen Win­dungskegel der Spule liegt.The object of the present invention is therefore to separate the roving, ie the fuse, when pulling roving bobbins off the flyer so that the sliver end lies on the upper winding cone of the bobbin.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,
daß die Vorspinnmaschine in einer Stellung stillgesetzt wird oder in einer Stellung ausläuft, in welcher die Preßfinger dicht unterhalb des oberen Umkehrpunktes der letzten Windungsschicht an der Spule stehen,
daß danach die nicht drehenden oder auslaufenden Spulen und Flü­gel axial relativ zueinander so bewegt werden, daß die Preßfin­ger bis dicht unter den Umkehrpunkt der ersten Windungsschicht geführt werden,
daß anschließend die Spulen um mindestens eine halbe Umdrehung vorwärts gedreht werden,
daß entsprechend der Beschaffenheit des zu bearbeitenden Mate­rials die Lunten zwischen dem Streckwerk und den Preßfingern ge­lockert werden und
daß zum abschließenden Trennvorgang die nichtdrehenden Spulen und Flügel axial relativ zueinander so bewegt werden, daß die Preßfinger nach unten geführt werden.According to the invention, this object is achieved by
that the roving machine is stopped in a position or runs out in a position in which the pressing fingers are located just below the upper reversal point of the last winding layer on the spool,
that the non-rotating or outgoing coils and wings are then moved axially relative to one another in such a way that the pressing fingers are guided to just below the point of reversal of the first winding layer,
that the coils are then turned forward by at least half a turn,
that according to the nature of the material to be processed, the fuses between the drafting system and the pressing fingers are loosened and
that for the final separation process, the non-rotating coils and wings are moved axially relative to one another so that the pressing fingers are guided downwards.

Hierdurch ergibt sich der Vorteil, daß das Ende der jeweiligen Lunte auf dem oberen Windungskegel liegt, wodurch verhindert wird, daß das Vorgarn bei nachfolgendem, hängendem Transport der Vorgarnspulen abfällt. Durch die mindestens einfache Umschlin­gung der Spule wird ein Herabziehen der Lunte bei Nach-Unten-Be­wegung der Preßfinger vermieden; durch das Lockern der Lunte liegt der Punkt, an dem die Lunten auseinandergleiten, auf dem zylindrischen Bereich der Wicklung, wobei vorteilhafterweise auch am Preßfinger ein kurzer Vorgarnbart verbleibt.This has the advantage that the end of the respective sliver lies on the upper winding cone, which prevents the roving from falling off during subsequent hanging transport of the roving bobbins. The at least simple wrapping around the coil prevents the fuse from being pulled down when the pressing fingers move downward; by loosening the fuse, the point at which the fuse slides apart lies on the cylindrical area of the winding, a short roving also advantageously remaining on the press finger.

Ein weiterer Vorteil ist, daß das erfindungsgemäße Verfahren keiner zusätzlichen Vorrichtung bedarf, welche nicht ohnehin schon an der Vorspinnmaschine vorhanden ist. Der erforderliche Verfahrensablauf läßt sich ohne weiteres an der Steuereinrich­tung der Vorspinnmaschine programmieren.Another advantage is that the method according to the invention does not require any additional device, which does not anyway is already present on the roving machine. The required process sequence can be easily programmed on the control device of the roving machine.

Zum besseren Abgleiten auf dem oberen Windungskegel der Spule weist der Preßfinger vorteilhafterweise eine Abschrägung auf.For better sliding on the upper winding cone of the coil, the press finger advantageously has a bevel.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. In der Zeichnung zeigen:

  • Fig. 1 bis 5 in schematischer Seitenansicht die einzelnen Ver­fahrensschritte zum Trennen des Vorgarns
  • Fig. 6 eine Seitenansicht eines Spulenkörpers mit herabhängendem Luntenende im Bereich des oberen Windungskegels, teils gebrochen,
  • Fig. 7 eine schematische Seitenansicht der Abschrägung des Preß­fingers im Bereich des oberen Windungskegels einer Spule, teils gebrochen.
The invention is described below with reference to an embodiment shown in the drawing. The drawing shows:
  • 1 to 5 in a schematic side view the individual process steps for separating the roving
  • 6 is a side view of a coil body with a depending sliver end in the area of the upper winding cone, partly broken,
  • Fig. 7 is a schematic side view of the bevel of the pressing finger in the region of the upper winding cone of a coil, partly broken.

Gemäß den Fig. 1 bis 5 befindet sich oberhalb eines Maschinenge­stells einer Vorspinnmaschine ein aus mehreren Walzenpaaren be­stehendes Streckwerk 2. Das Maschinengestell 1 weist eine Flü­gelbank 3 auf, in welcher eine Vielzahl von Flügeln an ihrem Kopf drehbar gelagert und über nicht näher dargestellte An­triebsmittel angetrieben sind. Diese Flügel 4 weisen jeweils einen hohlen Flügelarm auf, an dessen unterem Ende je ein Preß­finger 5 schwenkbar gelagert ist.According to FIGS. 1 to 5, a drafting unit 2 consisting of several pairs of rollers is located above a machine frame of a pre-spinning machine. The machine frame 1 has a wing bench 3, in which a plurality of wings are rotatably mounted on their heads and driven by drive means, not shown . These wings 4 each have a hollow wing arm, at the lower end of which a press finger 5 is pivotally mounted.

Das Maschinengestell 1 ist mit einer Führung 6 versehen, auf welcher eine Konsole 7 höhenbewegbar gelagert ist. Diese Konsole 7 ist mit einer, um einen Drehpunkt 8 kippbar gelagerten Spulen­bank 9 verbunden. In der Spulenbank 9 sind koaxial zu den Flü­geln 4 Spulen 10 auf Spulenspindeln gelagert.The machine frame 1 is provided with a guide 6, on which a bracket 7 is mounted such that it can be moved. This console 7 is connected to a coil bank 9 which is pivotably mounted about a pivot point 8. In the coil bank 9, 4 coils 10 are mounted coaxially to the wings on coil spindles.

Zwischen der Konsole 7 und der Spulenbank 9 befinden sich Kol­ben-Zylindereinheiten 11, durch welche die Spulenbank 9 vom Maschinengestell 1 weggekippt werden kann.Piston-cylinder units 11, through which the coil bank 9 can be tilted away from the machine frame 1, are located between the console 7 and the coil bank 9.

Nach Fertigstellung der Vorgarnspulen 10 wird die Vorspinn­maschine in einer Stellung stillgesetzt oder läuft in einer Stellung aus, in welcher die Preßfinger 5 gemäß Fig. 1 dicht un­terhalb des oberen Umkehrpunktes der letzten Windungsschicht an der Spule 10 stehen.After completion of the roving bobbins 10, the roving machine is stopped in one position or runs down in a position in which the pressing fingers 5 according to FIG. 1 are close to the upper turning point of the last winding layer on the bobbin 10.

Nach Fig. 2 werden danach die nichtdrehenden oder auslaufenden Spulen 10 und Flügel 4 axial relativ zueinander so bewegt, daß die Preßf inger 5 bis dicht unter den Umkehrpunkt der ersten Win­dungsschicht geführt werden.According to Fig. 2, the non-rotating or outgoing coils 10 and 4 wings are moved axially relative to each other so that the Preßf fingers 5 are performed close to the point of reversal of the first winding layer.

Gemäß Fig. 3 werden anschließend die Spulen 10, wie in Pfeil­richtung dargestellt, um mindestens eine halbe Umdrehung vor­wärts gedreht. Aus Fig. 4 ist ersichtlich, daß danach die Lunten 12 zwischen dem Streckwerk 2 und den Preßfingern 5 gelockert werden, und zwar entsprechend der Beschaffenheit des zu bearbei­tenden Materials. Nach dieser Lockerung werden gemäß Fig. 5 zum abschließenden Trennvorgang die nichtdrehenden Spulen 10 und Flügel 4 gemäß Pfeilrichtung axial relativ zueinander so bewegt, daß die Preßfinger 5 nach unten geführt werden. Der Trennvorgang ist damit beendet.3, the coils 10 are then rotated forward by at least half a turn, as shown in the direction of the arrow. From Fig. 4 it can be seen that thereafter the fuses 12 between the drafting device 2 and the pressing fingers 5 are loosened, depending on the nature of the material to be processed. After this loosening, the non-rotating coils 10 and wings 4 are moved axially relative to one another in accordance with the direction of the arrow so that the pressing fingers 5 are guided downward for the final separation process. The separation process is now complete.

Nach Fig. 6 wird hierdurch die vorteilhafte Wirkung erzielt, daß das Ende der Lunte 12′ auf dem oberen Windungskegel 14 der Spule 10 liegt, wodurch verhindert wird, daß das Vorgarn bei einem nachfolgenden, hängenden Transport der Vorgarnspulen 10 abfällt. Es liegt eine mindestens einfache Umschlingung der Spule 10 durch die Lunte 12′ vor, so daß darüberhinaus vorteilhafterweise das Herabziehen der Lunte beim Nach-Unten-Bewegen des betreffenden Preßfingers 5 vermieden wird. Weiterhin ist aus Fig. 6 ersichtlich, daß durch das Lockern der Lunte der Punkt, an dem die Lunte auseinandergleitet, auf dem zylindrischen Bereich 18 der Wicklung der Vorgarnspule 10 liegt.According to Fig. 6, the advantageous effect is achieved that the end of the fuse 12 'on the upper cone 14 of the bobbin 10, thereby preventing the roving from falling during a subsequent, hanging transport of the roving bobbins 10. There is an at least simple looping of the coil 10 through the fuse 12 ', so that, moreover, advantageously the pulling down of the fuse when moving downward the pressing finger 5 concerned is avoided. 6 that the point, by loosening the fuse, on which the fuse slides apart, lies on the cylindrical region 18 of the winding of the roving bobbin 10.

Nach Fig. 3 besteht auch die Möglichkeit, daß die Spuien 10 um mehrere Umdrehungen vorwärts gedreht werden, wodurch eine mehr­fache Umschlingung der Vorgarnspulen erzielt wird.According to Fig. 3 there is also the possibility that the spools 10 are rotated forward by several revolutions, whereby multiple wrapping of the roving bobbins is achieved.

Die Preßfinger 5 müssen so gestaltet sein, daß gewährleistet ist, daß die Lunten 12 beim Nach-Oben- oder Nach-Unten-Bewegen der Preßfinger 5 nicht ausgefädelt werden. Außerdem kann vor­teilhafterweise die Unterkante des Preßfingers 5 zum besseren Abgleiten auf dem oberen Windungskegel 14 vorzugsweise mit einer Abschrägung 20 versehen sein, woraus eine Verbesserung im Ver­fahrensablauf resultiert.The pressing fingers 5 must be designed in such a way that it is ensured that the fuses 12 are not unthreaded when the pressing fingers 5 are moved upwards or downwards. In addition, the lower edge of the pressing finger 5 can advantageously be provided with a bevel 20 for better sliding on the upper winding cone 14, which results in an improvement in the process flow.

Durch das erfindungsgemäße Verfahren sind keine zusätzlichen Vorrichtungen erforderlich; die einzelnen Verfahrensschritte lassen sich ohne weiteres an einer bereits an der Vorspinnma­schine vorhandenen Steuereinrichtung programmieren.The inventive method means that no additional devices are required; the individual process steps can be easily programmed on a control device already present on the pre-spinning machine.
