Die Erfindung bezieht sich auf eine Vorrichtung zum Schneiden von auf Spulen aufgewickelten Fäden oder Garnen zu Stapelfasern. .The invention relates to a device for cutting threads or yarns wound on bobbins into staple fibers. .
Auf Spulen aufgewickelte Fäden oder Garne sind manchmal we* ~ert ungenügender Qualität des aufgewickelten Materials für die Weiterverarbeitung nicht geeignet. Um die ganz oder teilweise bewickelten Spulen von dem aufgewickelten Material zu befreien wurden eine Reihe von Abstreifvorrichtungen vorgeschlagen, die ein schnelles Entfernen der Garne oder Fäden bewirken sollen, ohne daß die Spulen dabei beschädigt werden (US-patentschriften 2 609 876; 2 613 425; englische Patentschrift 705 281 und DAS 1 278 906). über die weitere Behandlung der von diesen Abstreifvorrichtungen erzeugten Garn- bzw. Fadenabfälle sagen diese Vorschläge nichts aus, jedoch läßt sich feststellen, daß die Garn- bzw» Fadenabfälle .nach dem Abstreifen in einer Form vorliegen, die sich höchstens für eine erneute Aufbereitung au einer vor dem Arbeitsgang dee Spinnens liegenden Zwischenstufe eignet!·Threads or yarns wound on bobbins are sometimes unsuitable for further processing if the quality of the wound material is insufficient. In order to free the wholly or partially wound bobbins from the wound material, a number of stripping devices have been proposed which are intended to effect rapid removal of the yarns or threads without damaging the bobbins in the process (US patents 2,609,876; 2 613 425; English patent specification 705 281 and DAS 1 278 906). on the further treatment of the yarn or thread waste generated by these stripper these proposals do not say anything, but it can be said that the yarn or "yarn waste .after stripping present in a form that most au for a new reprocessing before the operation dee spinning lying intermediate is! ·

weitere Verarbeitung als endlose Fäden oder Garne nicht ausreicht, besitzt meist eine ausreichende Qualität für· die Verwendung bei der Herstellung von Vlies- oder Füllstoffen. Die Verarbeitung zu Vlies- oder Füllstoffen setzt aber voraus, daß das Material in Form von Stapelfasern bestimmter Länge zur Verfügung steht.further processing as endless threads or yarns is not sufficient, usually has a sufficient quality for use in the production of nonwovens or fillers. The processing to fleece or fillers requires that the material is in the form of staple fibers of a certain length is available.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zu entwickeln, die die Faden oder Garne auf ganz oder teilweise bewickelten Spulen zu Stapelfasern der gewünschten Länge für eine unmittelbare Weiterverarbeitung schneidet.The invention is therefore based on the object of a device to develop the thread or yarn on wholly or partially wound bobbins into staple fibers of the desired Cuts length for immediate further processing.
Erfindungsgemäß wird dies dadurch erreicht, daß eine ganz oder teilweise bewickelte Spule zwischen zwei oder mehreren, radial zur Spulenachse mit gleichmäßigem Abstand voneinander angeordneten, sich drehenden Rundmessern, deren Achsen in einer Ebene liegen, in Drehrichtung des· Rundmessers verschiebbar ist.According to the invention this is achieved in that a wholly or partially wound coil between two or more, Rotating circular knives arranged radially to the spool axis at a uniform distance from one another, the axes of which are in lie in one plane, can be moved in the direction of rotation of the circular knife.
überraschenderweise hat sich gezeigt, daß die Fadenlagen der bewickelten Spule von den gleichzeitig im Eingriff stehenden Rundmessern einwandfrei geschnitten werden. Die gewünschte Schnittlänge der Fasern, die für die Vlies- oder Füllstoffherstellung Üblicherweise größer als 20 mm aber kleiner als etwa 150 mm sein muß, erhält man durch entsprechende Anzahl der über den Umfang verteilten Rundmesser*Surprisingly, it has been shown that the thread layers of wound bobbin can be perfectly cut by the circular knives that are engaged at the same time. The desired Cut length of the fibers used for the manufacture of nonwovens or fillers Usually larger than 20 mm but smaller than about 150 mm is obtained by a corresponding number of circular knives distributed over the circumference *
In weiterer Ausgestaltung der Erfindung 1st vorgesehen, daß die Rundmesser in radialer Richtung zur Spulenachse einstellbar sind. Die Vorrichtung läßt sich durch diese Anordnung dem Jeweils verwendeten Spulendurchmesser anpassen« Auch die beim Naohsohlelfen der Rundmesser auftretende l^rkleinerung des Durohmessers wird durch die radiale Versohidfeba^keit der Rundmesser ausgeglichen»In a further embodiment of the invention, provision is made for the circular knives to be adjustable in the radial direction relative to the bobbin axis are. The device can be through this arrangement Adapt the reel diameter used in each case Durohmessers is due to the radial versohidfeba ^ ability of the Round knife balanced »

Eine 'zusätzliche Ausbildung der erfindungsgemäSen Vorrichtung besteht darin, daß die Rundmesser mittels in Drehrichtung angeordnete Düsen durch Kühlluft anblasbar sind. Bei Kühlung der Rundmesser kann die Schnittgeschwindigkeit erheblich gesteigert werden. Zusätzlich entfernt der Luftstrom die abgeschnittenen Pasern von den Schneidstellen und fördert sie in eine Auffangvorrichtung.An 'additional design of the device according to the invention consists in the fact that the circular knives can be blown on by cooling air by means of nozzles arranged in the direction of rotation. When cooling the circular knife, the cutting speed can be increased considerably. In addition, the airflow removes the cut fibers from the cutting points and promotes them in a catcher.
In einer bevorzugten Anordnung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß die Verschiebebewegung der ganz oder teilweise bewickelten Spule senkrecht nach unten erfolgt und die Ebene, in der^die Rundmesserachsen liegen, waagrecht ist. Bei dieser vorteilhaften Anordnung fallen, die abgeschnittenen Pasern unter dem Einfluß ihres Eigengewichts in einen unter der Schneidvorrichtung angebrachten Sammelbehälter.In a preferred arrangement of the device according to the invention it is provided that the displacement movement of the fully or partially wound coil takes place vertically downwards and the plane in which the circular knife axes lie is horizontal. With this advantageous arrangement, the cut pasers attached under the influence of their own weight in one under the cutting device Collection container.

tung 4 mit aufgesteckter Spule 7 sind die Rundmesser 8 radial zur Spulenachse mit gleichmäßigem Abstand voneinander angeordnet. Die Rundmesser S werden über die in einer Ebene liegenden Achsen 9 angetrieben. Die Achsen 9 sind auf nicht näher dargestellten Schlitten gelagert, die sich in radialer Richtung der Spule einstellen lassen. Die Rundmesser 8 nebst nicht näher dargestellten Antriebselementen werden von einem Gehäuse IO abgedeckt, -das eine trichterförmige öffnung 11 als Einlaßöffnung für die Spule 7 enthält. In den oberen Rand des Gehäuses 10 sind die Düsen 12 eingebaut, die über die Leitungen 13 mit Kühlluft versorgt werden. Unterhalb der Schneidvorrichtung steht der Auffangbehälter 14 für die abgeschnittenen Stapelfasern. Der Auffangbehälter 14 kann als Wagen ausgebildet sein.Device 4 with the spool 7 attached are the circular knives 8 arranged radially to the coil axis at an even distance from one another. The circular knives S are in a Axles 9 lying flat driven. The axes 9 are mounted on slides not shown in detail, which are in adjust the radial direction of the coil. The circular knife 8 together with drive elements not shown in detail are covered by a housing IO, the one funnel-shaped Opening 11 as an inlet opening for the coil 7 contains. The nozzles 12, which are supplied with cooling air via the lines 13, are built into the upper edge of the housing 10. The collecting container 14 for the cut staple fibers is located below the cutting device. The collecting container 14 can be designed as a carriage.
Zum Schneiden des Materials β auf der Spule 7 wird der Hubzylinder 2 umgeschaltet. Dabei bewegt sich die Spule 7* wie durch einen Pfeil angedeutet senkrecht nach unten, wobei das Material 6 von den in gleichmäßigem Abstand angeordneten Rundmessern, deren Drehrichtung durch Pfeile gekennzeichnet ist,gleichzeitig erfasst und aufgeschnitten wird. Die abgeschnittenen Pasern fallen unter der Wirkung ihres Eigengewichts und vom Kühlluftstrom unterstützt in den Auffangbehälter 14. Wenn die Spule 7 zwischen den Rundmessern 8 hindurchgelaufen ist, wird der Hubzylinder 2 erneut umgeschaltet. Dadurch kehrt sich die Bewegung der Spule um. Nach dem Erreichen der oberen Endlage des Kolbens des HubZylinders 2 kann die von den aufgewickelten Fäden bzw. Garnen befreite Spule aus der Spannvorrichtung 4 entfernt und eine volle Spule in die Spannvorrichtung eingesetzt werden. Nach dem Umschalten des Hubzylinders 2 wiederholt sich dann der oben beschriebene Vorgang.The lifting cylinder is used to cut the material β on the spool 7 2 switched. The coil 7 * moves vertically downwards as indicated by an arrow, with the material 6 from the evenly spaced circular knives, whose direction of rotation is indicated by arrows is, is captured and cut open at the same time. The cut strips fall under the effect their own weight and supported by the flow of cooling air in the collecting container 14. When the coil 7 has passed between the circular knives 8, the lifting cylinder 2 is again switched. This reverses the movement of the coil. After reaching the upper end position of the piston of the Lifting cylinder 2 can remove the bobbin freed from the wound threads or yarns from the tensioning device 4 and insert a full spool into the jig. After the lifting cylinder 2 has been switched over, it repeats itself then the process described above.
