Description

Verfahren und Vorrichtung zum Abschneiden eines aus einer Spinnmaschine in ununterbrochenem Strang austretenden Fadenbündels, insbesondere von Kunstseidenfäden Die Erfindung betrifft ein Verfahren, um ununterbrochen und rasch maschinell gelieferte Fadenbündel, insbesondere von Kunstseide, in beliebige, selbst kleinere Stapellängen zu zerschneiden.Method and device for cutting off a spinning machine Thread bundles emerging in an uninterrupted strand, especially of rayon threads The invention relates to a method for continuously and quickly machine-delivered Bundles of threads, especially artificial silk, in any, even smaller, staple lengths to cut up.

Bei den bisher bekannt gewordenen Vorrichtungen war man gezwungen; den Fadenvorschub ziemlich klein zu machen, um das gleichmäßige Abschneiden zu sichern. Bei Erhöhung der Vorschubgeschwindigkeit über eine gegebene Grenze hinaus war die Wirkung unregelmäßig und unbefriedigend.With the previously known devices one was forced; to make the thread feed rather small in order to ensure even cutting. When the feed rate was increased beyond a given limit, the Irregular and unsatisfactory effect.

Beim Bau von Stapelschneidmaschinen mit großer Vorschubgeschwindigkeit beruhte die größte Schwierigkeit, auf die man stieß, darin, daß während der sehr kurzen Zeitspanne zwischen zwei Schnitten das austretende Fadenbündel infolge seiner geringen Masse sich nicht gleichmäßig vorschob; infolgedessen erhielt man unregelmäßige Schnittlängen.When building pile cutting machines with high feed speeds the greatest difficulty encountered was that during the very short period of time between two cuts, the emerging thread bundle as a result of its small mass did not advance evenly; as a result, irregular ones were obtained Cutting lengths.

Im Gegensatz hierzu wird gemäß der Erfindung das austretende Fadenbündel durch die darauf wirkende Fliehkraft nach außen geschleudert und so zur Schneidvorrichtung gleichmäßig vorgeschoben.In contrast, according to the invention, the emerging thread bundle thrown outwards by the centrifugal force acting on it and thus to the cutting device advanced evenly.

Es ist auch vorgeschlagen worden, einen Faden oder ein Fadenbündel unmittelbar am freien Ende der Spinndüse abzuschneiden, wobei der Fadenvorschub jeweils von der Spinngeschwindigkeit abhängt.It has also been suggested to use a thread or a bundle of threads cut off immediately at the free end of the spinneret, with the thread feed each depends on the spinning speed.

Im Gegensatz dazu erfolgt gemäß der Erfindung das Abschneiden in einer gewissen Entfernung von den Spinndüsen, nachdem die Fäden eine genügende Festigkeit erlangt haben.In contrast, according to the invention, the cutting takes place in one certain distance from the spinnerets after the threads have sufficient strength have attained.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in schematischer Weise dargestellt.The drawing shows an embodiment of the subject matter of the invention shown in a schematic manner.

Die Vorrichtung enthält einen Aufgabetr ichter a, der ein Teilstück einer Scheibe b bildet, die mittels einer beliebigen Einrichtung, z. B. mittels eines um eine Scheibe c laufenden Riemens, rasch um ihre Achse umläuft.The device includes a feed hopper a, which forms a portion of a disc b , which by means of any device, for. B. by means of a belt running around a pulley c, rotates rapidly around its axis.

Das aus der vorangehenden Spinnmaschine mit bestimmter gleichförmiger Geschwindigkeit herauskommende Fadenbündel wird zum Trichter a geführt, den es, durch seine knieförmige Mündung vorrückend, durchsetzt. Sobald das Bündel bei d ankommt, wird es der infolge der raschen Drehung der Scheibe sich entwickelnden Fliehkraft ausgesetzt und kräftig längs des radialen Kanals d-e vor- geschoben.The thread bundle emerging from the preceding spinning machine at a certain uniform speed is led to the funnel a, through which it penetrates, advancing through its knee-shaped mouth. Once the bundle arrives at d, it is exposed to as a result of the rapid rotation of the disc developing centrifugal force and vigorously along the radial channel de pushed forward.

Beim Austritt aus dem Kanal an dessen Ende e schiebt sich das Fadenbündel während einer Umdrehung der Scheibe um ein, bestimmtes Stück vor und wird, indem es nach der vollzogenen Umdrehung der Scheibe an einer Schneide f vorbeikommt, am Rande der Austrittsöffnung abgeschnitten. Der abgeschnittene Stapel fällt durch sein Eigengewicht nach g herunter.When exiting the channel at its end e, the thread bundle is pushed during one revolution of the disc by a certain distance and is done by it passes a cutting edge f after the completed revolution of the disk, on Edge of the outlet cut off. The cut pile falls through its own weight down to g.

Bei jedem Umlauf der Scheibe wiederholt sich der beschriebene Vorgang derart, daß, wenn entweder die Zuführungsgeschwindigkeit der Gruppe oder die Winkelgeschwindigkeit der Scheibe oder endlich die Anzahl der Schneiden geändert werden, die verschiedensten Schneidlängen ermöglicht werden.The process described is repeated with each revolution of the disk such that if either the feeding speed of the group or the angular speed the disc or finally the number of cutting edges can be changed, the most varied Cutting lengths are made possible.
