Description

Die Erfindung betrifft eine Auflösewalze für Open-End Spinnmaschinen od.dgl. gemäß dem Oberbegriff von Anspruch 1.The invention relates to an opening roller for open-end spinning machines or the like. according to the preamble of claim 1.

Derartige Auflösewalzen werden in der Textilindustrie in großem Umfang eingesetzt. Sie dienen unter anderem dazu, das ihnen zugeführte Faserband in Einzelfasern aufzulösen. Dementsprechend sind sie von wesentlicher Bedeutung für das zu erzeugende Endprodukt. Dabei ist es wichtig, daß die Garnitur derartiger Auflösewalzen möglichst kontinuierlich und gleichmäßig im Faserfluß läuft.Such opening rollers are widely used in the textile industry. Among other things, they serve to dissolve the sliver fed to them into individual fibers. Accordingly, they are essential for the end product to be produced. It is important that the set of such opening rollers runs as continuously and evenly as possible in the fiber flow.

Grundsätzlich sind als Garnitur für derartige Walzen einzelne Nadeln bzw. Nadelleisten oder Sägezahndrähte bekannt. Letztere lassen sich zwar kostengünstig herstellen und aufziehen, gewährleisten aber nicht eine optimale Kämmqualität. Demgegenüber sind Nadelgarnituren sehr vorteilhaft, erfordern aber in der Regel einen höheren Aufwand bei der Erstgarnierung bzw. bei der in regelmäßigen Abständen erforderlich werdenden Erneuerung.In principle, individual needles or needle bars or sawtooth wires are known as a clothing for such rollers. The latter can be produced and wound up inexpensively, but they do not guarantee optimal combing quality. In contrast, are needle thread structures are very advantageous, but usually require more effort for the initial garnish or for the renewal that becomes necessary at regular intervals.

Zur Erzielung einer möglichst gleichmäßigen Verteilung der in das Faserband eingreifenden Spitzen über die Bearbeitungsbreite wird es in dem DE-GM 73 45 782 einleitend als bekannt beschrieben, Walzenkörper mit einer schraubenförmig umlaufenden Nut zur Aufnahme eines Sägezahndrahtes zu versehen. Der Sägezahndraht wird in einer derartigen Nut verspannt und erforderlichenfalls zusätzlich durch Kleben befestigt. Die Nuten derartiger vorbekannter Walzenkörper verlaufen derart um diesen herum, daß die Steigung der Schraubenlinien mit der Längsachse des Walzenkörpers in der Projektion einen Winkel von etwas weniger als 90° einschließen. Derartige vorbekannte Walzenkörper mit einer entsprechenden Garnierung weisen die grundsätzlichen, systembedingten Nachteile einer Sägezahndrahtgarnierung auf, welche sich zudem nicht einfach und problemlos erneuern läßt.In order to achieve as uniform a distribution as possible of the tips engaging in the fiber sliver over the processing width, it is described in the introduction in DE-GM 73 45 782 as known to provide roller bodies with a helical circumferential groove for receiving a sawtooth wire. The sawtooth wire is clamped in such a groove and, if necessary, additionally fastened by gluing. The grooves of such previously known roll body extend in such a way around the latter, that the pitch of the helical lines include less with the longitudinal axis of the roll body in the projection an angle of slightly as 9 0 °. Such known roller bodies with a corresponding garnish have the basic, system-related disadvantages of a sawtooth wire garnish, which, moreover, cannot be easily and easily renewed.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Auflösewalze zu schaffen, welche bei kontinuierlichem, gleichmäßigem Eingriff in das Faserband die Verwendung leichter und damit unwucht-unempfindlicher Walzenkörper ermöglicht, wobei zudem Neugarnierungen im Betrieb des Anwenders problemlos und schnell vorgenommen werden können.Proceeding from this, the object of the invention is to create an opening roller which, with continuous, even engagement in the fiber sliver, enables the use of light and thus unbalance-insensitive roller bodies, in addition to which reorganizations can be carried out quickly and easily in the operation of the user.

Diese Aufgabe wird gelöst durch eine Auflösewalze mit den Merkmalen des kennzeichnenden Teils von Anspruch 1. Das Vorsehen einer schraubenförmig umlaufenden Ausnehmung mit Hinterschneidungen ermöglicht es,This object is achieved by an opening roller with the features of the characterizing part of claim 1. The provision of a screw-shaped circumferential recess with undercuts enables

Nadelstreifen mit einer gewissen Eigenelastizität des Fußes einzusetzen, wobei die Nadelstreifen durch die schraubenförmige Verwindung bereits ohne zusätzliche Festlegungsmittel parallel zur Nutlängsachse gehalten werden, und wobei in radialer Richtung ein der Hinterschneidung entsprechender korrespondierender Vorsprung am Fuß der Nadelstreifen für Halt sorgen kann. Diese Nadelstreifen lassen sich also einsetzen, ohne daß Erwärmungen für das Lösen von Leim- oder Lötverbindungen durchgeführt werden müssen, welche dazu führen können, daß die so behandelten Walzen neu ausgewuchtet werden müssen, was einen entsprechenden technischen Aufwand erfordert. Zudem lassen sich Walzenkörper mit einer schraubenförmig umlaufenden Nut, welche entsprechend der Erfindung in spitzem Winkel zur Längsachse des Grundkörpers verläuft, durch die Verwendung einer Spiralfräseinrichtung kostengünstig und mit der erforderlichen Präzision aus leichten Aluminiumteilen herstellen. Letztlich wird noch durch die erfindungsgemäße Anordnung der Nadelstreifen eine optimale Nadelverteilung über die Führungsbreite erzielt.Use pinstripes with a certain intrinsic elasticity of the foot, the pinstripes being held parallel to the longitudinal axis of the groove without additional fixing means due to the helical twist, and in the radial direction a corresponding projection on the base of the pinstrip corresponding to the undercut can provide support. These pinstripes can thus be used without having to carry out heating for loosening glue or solder connections, which can lead to the rollers treated in this way having to be re-balanced, which requires a corresponding technical outlay. In addition, roller bodies with a helical circumferential groove, which according to the invention runs at an acute angle to the longitudinal axis of the base body, can be produced inexpensively and with the required precision from light aluminum parts by using a spiral milling device. Ultimately, an optimal needle distribution over the guide width is achieved by the arrangement of the pinstripes according to the invention.

Eine besonders vorteilhafte Dimensionierung für den Winkel zwischen den Nuten und der Längsachse gibt Anspruch 2 an. Die gemäß Anspruch 3 vorgesehene Ausbildung der Hinterschneidung als Schwalbenschwanzprofil ermöglicht einen besonders zuverlässigen Sitz der Nadelstreifen.Claim 2 specifies a particularly advantageous dimensioning for the angle between the grooves and the longitudinal axis. The design of the undercut as a dovetail profile, provided in accordance with claim 3, enables a particularly reliable fit of the pinstripes.

Anspruch 4 gibt ein Verhältnis für die Dimensionierung von Nuten-Steigung und Zylinderlängsachse an, durch welches eine sehr günstige Nadelverteilung erreicht wird.Claim 4 specifies a ratio for the dimensioning of the groove pitch and the cylinder longitudinal axis, through which a very favorable needle distribution is achieved.

Anspruch 5 schließlich bezieht sich auf eine Nadelleiste, welche insbesondere für eine erfindungsgemäße Auflösewalze geeignet ist.Finally, claim 5 relates to a needle bar, which is particularly suitable for an opening roller according to the invention.

Eine erfindungsgemäße Auflösewalze umfaßt einen Grundkörper 1. In diesen Grundkörper 1 sind mittels einer Spiralfräseinrichtung um den Umfang verteilt zueinander parallelverlaufende Nuten 2 eingebracht. Diese Nuten 2 weisen im Querschnitt (vgl. Fig. 2) ein Schwalbenschwanzprofil auf. Sie verlaufen relativ zum zylinderförmigen Grundkörper 1 schraubenlinienförmig.An opening roller according to the invention comprises a base body 1. Grooves 2 running parallel to one another are introduced into this base body 1 by means of a spiral milling device. In cross section (see FIG. 2), these grooves 2 have a dovetail profile. They run helically relative to the cylindrical base body 1.

Jede einzelne Nut 2 weist gegenüber der Längsachse 3 des Grundkörpers 1 in der Projektion eine Steigung α zwischen 5° und 30° auf. Im Ausführungsbeispiel wurde eine Steigung von α=13° gewählt.Each individual groove 2 has an inclination α between 5 ° and 30 ° in relation to the longitudinal axis 3 of the base body 1 in the projection. In the exemplary embodiment, a slope of α = 13 ° was chosen.

Die Steigung α ist bezogen auf die Länge 1 des Grundkörpers bzw. die Breite d der Nuten 2 so gewählt, daß in einer Richtung parallel zur Längsachse 3 der Mittelpunkt 4 des Endes einer Nut 2 an einer Stirnseite 5 des Grundkörpers 1 in gleicher Höhe liegt wie der Mittelpunkt 6 einer benachbarten Nut 2 an der jeweils anderen Stirnseite 7 des Grundkörpers 1.The slope α is chosen so that the length 1 of the base body or the width d of the grooves 2 in a direction parallel to the longitudinal axis 3, the center point 4 of the end of a groove 2 on one end face 5 of the base body 1 is at the same height as the center point 6 of an adjacent groove 2 on the other end face 7 of the base body 1.

In Fig. 2 ist beispielsweise anhand einer Nut die Garnierung mittels eines Nadelstreifens 8 veranschaulicht. Ein derartiger Nadelstreifen besteht aus einer Mehrzahl in Reihe angeordneter Nadeln, welche untereinander durch einen Fuß 9 verbunden sind, welcher aus Kunststoff gespritzt ist. Hierfür wird ein Kunststoff gewählt, welcher einerseits eine formbeständige, strapazierfähige Oberfläche aufweist und andererseits über eine solche Eigenelastizität verfügt, daß er problemlos beim Einschieben in eine Nut 2 deren schraubenlinienförmigem Verlauf folgen kann. Hierdurch wird bereits ohne zusätzliche Festlegungsmittel ein fester, definierter Sitz des Nadelstreifens 8 erreicht. Zusätzlich können auf die Nabenansätze lo Haltescheiben zur Festlegung der Nadelstreifen aufgebracht werden.In FIG. 2, the garnishing is illustrated by means of a pinstrip 8, for example using a groove. Such a pinstripe consists of a plurality of needles arranged in a row, which are connected to one another by a foot 9 which is injection molded from plastic. For this purpose, a plastic is selected which on the one hand has a dimensionally stable, hard-wearing surface and on the other hand has such inherent elasticity that it can easily follow its helical course when inserted into a groove 2. As a result, a firm, defined fit of the pinstrip 8 is achieved without additional fixing means. In addition, lo washers can be applied to the hub lugs to fix the pinstripes.

Die erfindungsgemäße Ausgestaltung ermöglicht es bei hervorragenden Faserführungseigenschaften, daß der Benutzer selbst zu einem ihm genehmen Zeitpunkt eine neue Garnierung vornehmen kann, so daß die Kosten hierfür gering sind.The configuration according to the invention makes it possible, with excellent fiber guidance properties, for the user to carry out a new garnish himself at a convenient time, so that the costs for this are low.
