Abstract

Faserbänder müssen im Laufe des Spinnprozesses komprimiert oder deren Maß muß ermittelt werden. Zu diesem Zweck verwendet man sogenannte Nutenwalzenpaare, d.h. profilierte Walzen, welche eine beidseitig begrenzte Durchgangsnut für das Faserband definieren. Das Faserband wird durch einen Trichter (10) bis in die Durchgangsnut geführt. Dabei besteht die Gefahr, daß Einzelfasern sich zwischen den die seitliche Begrenzung der Nut bildenden Seitenflächen (6', 7') der Walzen (2, 3) verklemmen können. Diese Gefahr wird dadurch beseitigt, daß die Faseraustrittsöffnung (12) des Trichters (10) innerhalb des Bereiches des Keilspaltes (13) liegt, welcher begrenzt ist durch die Überlappungszone (15) der Seitenflächen (6', 7') der Walzen (2, 3).Slivers must be compressed during the spinning process or their dimensions must be determined. So-called grooved roller pairs are used for this purpose, i.e. profiled rollers, which define a through groove for the sliver that is limited on both sides. The sliver is fed through a funnel (10) into the through groove. There is a risk that individual fibers can become jammed between the side surfaces (6 ', 7') of the rollers (2, 3) that form the lateral boundary of the groove. This danger is eliminated in that the fiber outlet opening (12) of the funnel (10) lies within the area of the wedge gap (13), which is limited by the overlap zone (15) of the side surfaces (6 ', 7') of the rollers (2, 3).

Description

Die Erfindung betrifft eine Vorrichtung zum kontinuierlichen Komprimieren oder zum Ermitteln der Masse eines Faserbandes mit einem Paar gegeneinanderpressbaren Walzen, deren Peripherien derart ineinandergreifen, dass eine seitlich begrenzte Klemmzone entsteht sowie einem das Faserband zuführenden Trichter.The invention relates to a device for continuous compression or for determining the mass of a fiber sliver with a pair of rollers that can be pressed against one another, the peripheries of which engage in one another in such a way that a laterally delimited clamping zone is created, and a funnel feeding the fiber sliver.

Komprimier- und Messvorrichtungen für Faserbänder aus Textilfasern im Anschluss an eine Karde oder an eine Strecke sind seit langem bekannt und im Einsatz.Compression and measuring devices for fiber tapes made of textile fibers following a card or on a draw frame have long been known and in use.

Aus einer jüngeren Veröffentlichung (DE-OS 28 02 735) ist eine Komprimiervorrichtung dieser Art bekannt geworden, bei welcher der Innenteil eines Trichters in den Keilspalt von zwei gegeneinanderpressbaren, scheibenförmigen Walzen hineinragt und der kegelstumpfförmige Aussenteil des Trichters die Stirnseiten der Walzen im Klemmbereich seitlich überdeckt und damit den Keilspalt nach aussen abschliesst. Zwar wird mit dieser Vorrichtung das Faserband nahe an den Klemmbereich der Walzen herangeführt, doch kann ein seitliches Verklemmen der Fasern zwischen den sich drehenden Walzenstirnflächen und den stillstehenden den Keilspalt- und Klemmbereich der Walzen seitlich abschliessenden Trichteraussenteil nicht verhindert werden.From a recent publication (DE-OS 28 02 735) a compression device of this type has become known, in which the inner part of a funnel protrudes into the wedge gap of two disc-shaped rollers that can be pressed against one another and the frustoconical outer part of the funnel laterally covers the end faces of the rollers in the clamping area and thus closes the wedge gap to the outside. With this device, the sliver is brought close to the clamping area of the rolls, but a lateral jamming of the fibers between the rotating roll end faces and the stationary funnel outer part closing the wedge gap and clamping area of the rollers laterally cannot be prevented.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, das seitliche Entweichen von Fasern aus dem Klemmbereich der Walzen und das daraus sich ergebende Verklemmen der Vorrichtung und Bildung von störenden Faseransammlungen zu vermeiden.The present invention is based on the object of preventing the lateral escape of fibers from the clamping area of the rollers and the resulting jamming of the device and formation of disruptive fiber accumulations.

Diese Aufgaben wurden erfindungsgemäss dadurch gelöst, dass die Faseraustrittsöffnung des Trichters innerhalb des Bereiches des Keilspaltes liegt, welcher begrenzt ist durch die Ueberlappungszone der Seitenflächen der Walzen.According to the invention, these objects were achieved in that the fiber outlet opening of the funnel lies within the area of the wedge gap, which is limited by the overlapping zone of the side surfaces of the rollers.

Weitere vorteilhafte Ausführungsformen der Vorrichtung ergeben sich aus den Ansprüchen 2 bis 4.Further advantageous embodiments of the device result from claims 2 to 4.

Anhand illustrierter Ausführungsbeispiele wird die Erfindung näher erläutert:

  • Es zeigen:
    • Fig. 1 und 2 einen Querschnitt durch den Klemmbereich zweier verschiedener Walzenanordungen,
    • Fig. 3 einen Querschnitt längs Linie III-III in Fig. l,
    • Fig. 4 einen Querschnitt längs Linie IV-IV in Fig. 2.
The invention is explained in more detail on the basis of illustrated exemplary embodiments:
  • Show it:
    • 1 and 2 a cross section through the clamping area of two different roller arrangements,
    • 3 shows a cross section along line III-III in FIG. 1,
    • 4 shows a cross section along line IV-IV in FIG. 2.

In den Figuren 1 und 2 sind je ein Querschnitt durch die Klemm- bzw. Komprimierlinien oder -zonen 1 von zwei verschiedenen Ausbildungen von Walzenpaaren 2,3, bzw. 4,5 dargestellt. Die Walze 3 weist eine periphere Nut 6 auf, in welche ein peripher verlaufender Flansch 7 der Walze 2 mit geringem Spiel zwischen den Seitenflächen 7' des Flansches 7 und den Seitenflächen 6' der Nut 6 eingreift. Eine etwas andere Ausführungsform ist in Fig. 2 dargestellt. Die Peripherien der Walzen 4 und 5 sind gegengleich treppenförmig gestaltet und bilden, spiegelbildlich angeordnet, im Zentrum ebenfalls eine Komprimier-oder Klemmlinie 1. Auch hier liegen die Seitenflächen 17 und 18 der Walze 4 mit geringem Spiel zu den Seitenflächen 19 und 20 der Walze 5. Die Drehachsen 8,9 der Walzen 2,3, bzw. 4,5 werden in üblicher Weise gegeneinander gepresst und deren gegenseitiger Achsabstand d kann als Messgrösse herangezogen werden.In Figures 1 and 2 are a cross section through Clamping or compression lines or zones 1 of two different configurations of roller pairs 2, 3, and 4, 5 respectively. The roller 3 has a peripheral groove 6, in which a peripheral flange 7 of the roller 2 engages with little play between the side surfaces 7 'of the flange 7 and the side surfaces 6' of the groove 6. A somewhat different embodiment is shown in FIG. 2. The peripheries of the rollers 4 and 5 are designed in the same way in a step-like manner and, arranged in mirror image, likewise form a compression or clamping line 1 in the center The axes of rotation 8, 9 of the rollers 2, 3, and 4, 5 are pressed against one another in the usual way and their mutual center distance d can be used as the measurement variable.

Die Fig. 3 zeigt die Lage des erfindungsgemässen Faserbandtrichters 10 in bezug auf die Walzenpaare 2,3. Die Trichtermittelachse 11 des Trichters 10 verläuft im wesentlichen rechtwinklig zur Verbindungsebene der beiden Walzenachsen 8,9 durch die Klemmlinie 1. Die ausgangsseitige Oeffnung 12 des Trichters 10 reicht gerade soweit in den Keilspalt 13 vor der Klemmlinie 1, dass ein aus der Oeffnung 12 austretendes Faserband 14 sich bis zur Klemmlinie 1 nicht über deren seitliche Ausdehnung a (Breite der Klemminie 1) hinaus ausbreiten kann. Die seitliche Begrenzung für das Faserband 14 ist durch diese Anordnung innerhalb der Ueberlappungszone 15 der Seitenflächen 6' der Nut 6 und der Seitenflächen 7' des Flansches gewährleistet und ein Verklemmen von einzelnen Fasern aus dem Verband des Faserbandes 14 ist ausgeschlossen. Analog zeigt Fig. 4 die Verhältnisse bei treppenförmiger Ausgestaltung der Walzen 4,5, wo sich die Seitenflächen 17, 18 und 19, 20 mit geringem Spiel gegenüberliegen.3 shows the position of the sliver funnel 10 according to the invention in relation to the roller pairs 2, 3. The funnel center axis 11 of the funnel 10 runs essentially at right angles to the connecting plane of the two roller axes 8, 9 through the clamping line 1. The opening 12 of the funnel 10 on the output side extends just so far into the wedge gap 13 in front of the clamping line 1 that a sliver emerging from the opening 12 14 cannot extend beyond the lateral extension a (width of the clamping line 1) up to the clamping line 1. The lateral limitation for the sliver 14 is ensured by this arrangement within the overlap zone 15 of the side surfaces 6 'of the groove 6 and the side surfaces 7' of the flange and jamming of individual fibers from the bandage of the sliver 14 is excluded. Analogously, Fig. 4 shows the situation with stair Miger design of the rollers 4,5, where the side surfaces 17, 18 and 19, 20 face each other with little play.

Der stillstehende Trichter 10 bildet damit an keiner Stelle Teil der seitlichen Begrenzung des Spaltes 13. Es ist damit zum vornherein ausgeschlossen, dass allfällig doch einmal seitlich aus der Klemmlinie 1 austretende Fasern sich zwischen einem bewegten und einem stationären Teil der Vorrichtung verfangen können.At no point does the stationary funnel 10 form part of the lateral boundary of the gap 13. It is thus ruled out from the outset that any fibers that emerge laterally from the clamping line 1 can get caught between a moving and a stationary part of the device.

Vorzugsweise wird der maximale Durchmesser der Oeffnung 12 des Trichters 10 noch geringer als die seitliche Ausdehnung a der Klemmlinie 1, bzw. des Keilspaltes 13, gehalten. Um das Faserband 14 mit grösstmöglichem Querschnitt möglichst nahe an die Klemmlinie 1 heranführen zu können, ist der innerhalb der Ueberlappungszone 15 der Seitenflächen 6'7', bzw. 17, 18 und 19,20 verlaufende Teil der Trichterbohrung 16 zylindrisch angefertigt.The maximum diameter of the opening 12 of the funnel 10 is preferably kept even smaller than the lateral extent a of the clamping line 1, or of the wedge gap 13. In order to be able to bring the sliver 14 with the largest possible cross-section as close as possible to the clamping line 1, the part of the funnel bore 16 running within the overlap zone 15 of the side surfaces 6'7 'or 17, 18 and 19.20 is made cylindrically.

Diese Ausbildungen und Massnahmen verhindern zum vornherein die Ausbreitung des Faserbandes 14 vor und während des Verdichtungsvorganges. Damit ist aber gleichzeitig die Gefahr des Austretens von Fasern in die stirnseitigen Bereiche 6',7', bzw. 17,18; 19,20 der Walzen 2,3, bzw. 4,5 gebannt.These designs and measures prevent the sliver 14 from spreading before and during the compression process. At the same time, however, there is a risk of fibers escaping into the end regions 6 ', 7' or 17, 18; 19.20 of the rollers 2.3 and 4.5, respectively.
