Abstract

The present invention concerns the production of fancy yarns, in which during open-end spinning a roving is supplied program-controlled to the spinning unit for the yarn to be produced. According to the invention at least one roving bobbin is supported by a support member, which is detachably arranged on a can used as a receptable for the fibre material to be processed. The bobbin creel used up to the present for the bobbins impairs the accessability of the winding locations for the fancy yarn produced. This creel, according to the invention, no longer is required. Thus, the cumbersome mounting and dismantling of the creel in changing over from normal yarn to fancy yarn and vice-versa is dispensed with. According to the invention the alterations required for such changes of the yarn production mode are extremely simple.

Description

Die vorliegende Erfindung bezieht sich auf eine Einrichtung an einer Offenend-Spinnmaschine zur Herstellung eines Effektgarnes, wobei jeder Spinneinheit der Offenend-Spinnmaschine in einer Kanne gelagertes Faserband und auf Spulen aufgespultes Vorgarn zugeführt werden.The present invention relates to a device on an open-end spinning machine for producing a fancy yarn, wherein each spinning unit of the open-end spinning machine is supplied with sliver stored in a can and roving spooled onto bobbins.

Beim Herstellen von Effektgarnen in der genannten Weise müssen zusätzlich zu den beim Spinnen gebräuchlichen Kannen, in welchen das zu verspinnende Faserband gelagert ist, auch noch die Spulen für das den Effekt erzeugende Vorgarn untergebracht werden. Diese wurden bis anhin unmittelbar vor den Stellen, wo das Aufspulen des Effektgarnes stattfindet, an Gattern angebracht. Dadurch wird die Zugänglichkeit zu diesen Stellen und die Übersichtlichkeit im Spinnsaal verschlechtert. Da beim Spinnen eines gewöhnlichen Garnes die für diese Vorgarnspulen verwendeten Spulengatter nicht gebraucht werden, muss man sie für diesen Fall abmontieren, bzw. für das Spinnen von Effektgarnen wieder einbauen, was eine merkliche zusätzliche Arbeit bedeutet.When producing fancy yarns in the manner mentioned, in addition to the cans customary for spinning, in which the sliver to be spun is stored, the bobbins for the roving producing the effect must also be accommodated. So far, these have been attached to gates directly in front of the places where the fancy yarn is wound up. As a result, the accessibility to these places and the clarity in the spinning room are impaired. Since the bobbins used for these roving bobbins are not used when spinning an ordinary yarn, they have to be dismantled in this case or reinstalled for spinning fancy yarns, which means a noticeable additional work.

Diese Nachteile sollen gemäss der Erfindung vermieden werden. Diese ist dadurch gekennzeichnet, dass an der Kanne ein Spulenträger wegnehmbar angebracht ist, welcher mindestens ein Tragelement aufweist, welches zum Befestigen einer Vorgarnspule dient.These disadvantages are to be avoided according to the invention. This is characterized in that a bobbin is removably attached to the can, which has at least one support element, which serves to fasten a roving bobbin.

Gemäss vorliegender Erfindung ist somit ein spezielles Spulengatter und damit dessen Montage und Demontage beim Wechsel vom gewöhnlichen Garn zum Effektgarn und umgekehrt nicht nötig. Die Spulenträger werden an Kannen für das Faserband einfach angehängt und bei Nichtgebrauch von diesen weggehoben und beiseite gestellt. Dieser Wechsel ist somit von maximaler Einfachheit. Zudem sind die Spulenträger in der Herstellung problemlos und einfach.According to the present invention, a special creel and thus its assembly and disassembly when changing from ordinary yarn to fancy yarn and vice versa is not necessary. The bobbins are simply attached to cans for the sliver and lifted away from them when not in use and set aside. This change is therefore of maximum simplicity. In addition, the coil carriers are easy and simple to manufacture.

Im folgenden sei die Erfindung an Hand eines Ausführungsbeispiels und der Zeichnung näher erläutert. In der letzteren ist

  • Fig. 1 eine schematische Darstellung, welche die erfindungsgemässe Einrichtung in Verbindung mit einer Spinnmaschine zeigt und
  • Fig. 2 eine perspektivische Darstellung eines an einer Faserbandkanne angebrachten Spulenträgers.
The invention is explained in more detail below with the aid of an exemplary embodiment and the drawing. In the latter is
  • Fig. 1 is a schematic representation showing the device according to the invention in connection with a spinning machine and
  • Fig. 2 is a perspective view of a bobbin attached to a sliver can.

In beiden Figuren bezeichnen gleiche Bezugszahlen gleiche Teile.In both figures, the same reference numbers designate the same parts.

Fig. 1 zeigt eine Spinnmaschine 11 mit einer Spinneinheit 12. Kannen 13 dienen als Behälter für zu verspinnendes Faserband 14, von dem ein zur Spinneinheit 12 laufendes Stück gezeichnet ist. Von einer Vorgarnspule 15 läuft ein Vorgarn 16 zu einem Streckwerk 17, durch welches das Vorgarn 16 nach einem Programm büschelartig auseinander gezogen wird und zu einer Speiseleitung 18 gelangt. Mittels Saugwirkung werden die einzelnen Faserbüschel durch diese Leitung 18 durchgesogen, um in die Spinneinheit 12 zu gelangen. Das gesponnene Produkt, nämlich das Effektgarn 21, wird zu einer Spule 22 aufgewickelt.1 shows a spinning machine 11 with a spinning unit 12. Cans 13 serve as containers for sliver 14 to be spun, of which a piece running to the spinning unit 12 is drawn. A roving 16 runs from a roving bobbin 15 to a drafting device 17, by means of which the roving 16 is pulled apart in tufts according to a program and reaches a feed line 18. The individual tufts of fibers are sucked through this line 18 by means of suction in order to get into the spinning unit 12. The spun product, namely the fancy yarn 21, is wound up into a bobbin 22.

Wie aus Fig. 2 ersichtlich ist, ist an der Kanne 13 ein Spulenträger 23 angebracht. Dieser umfasst eine vertikal angeordnete Stange 24, welche mit einem Handgriff 25, einem Haken 26 und einem Anlageglied 27 versehen ist. Ein horizontal angeordneter, gebogener Stab 28 ist fest mit der vertikalen Stange 24 verbunden und erstreckt sich beidseitig derselben. An jeder Hälfte des Stabes 28 ist ein Tragelement 31 befestigt. An jedem derselben hängt eine Vorgarnspule 15. Das von den Spulen 15 sich abwickelnde Vorgarn 16 wird durch je eine Öse eines an der Stange 24 befestigten Fadenführers 32 geführt. Der Spulenträger 23 wird an der Kanne 13 angebracht, indem der Träger 23 mittels des Hakens 26 an die Kanne angehängt wird. Die Spulen 15 sind drehbar an den Tragelementen 31 aufgehängt. Beim Abziehen des Vorgarns 16 drehen sie sich deshalb um ihre Achsen.As can be seen from FIG. 2, a coil carrier 23 is attached to the can 13. This comprises a vertically arranged rod 24, which is provided with a handle 25, a hook 26 and a contact member 27. A horizontally arranged, curved rod 28 is fixedly connected to the vertical rod 24 and extends on both sides thereof. A support element 31 is fastened to each half of the rod 28. A roving bobbin 15 hangs from each of them. The roving 16 that unwinds from the bobbins 15 is passed through an eyelet of a thread guide 32 fastened to the rod 24. The coil support 23 is attached to the can 13 by the support 23 being attached to the can by means of the hook 26. The coils 15 are rotatably suspended from the support elements 31. When the roving 16 is pulled off, they therefore rotate about their axes.

In einem anderen, nicht dargestellten Ausführungsbeispiel können an den Tragelementen 31 entsprechenden Tragelementen senkrecht nach oben stehende Zapfen vorgesehen sein. Auf jeden Zapfen ist in diesem Fall je eine Vorgarnspule fest aufgesteckt. Da unter diesen Umständen der Abzug des Vorgarnes über den Kopf erfolgt, ist hier kein Fadenführer notwendig.In another exemplary embodiment, not shown, pins corresponding to the support elements 31 can be provided with vertically upwardly extending pins. In this case, a roving spool is firmly attached to each peg. Since the roving is drawn off over the head under these circumstances, no thread guide is necessary here.

Falls die Kanne 13, wie in Fig. gezeigt, eine kreiszylindrische Seitenwand aufweist, wird vorteilhafterweise ein gekrümmter Stab 28 verwendet, bei welchem der Krümmungsradius gleich dem Radius der zylindrischen Seitenwand ist. Man erhält auf diese Weise eine saubere Anlage des Stabes 28 an die Kanne 13. Auch das Anlageglied 27 wird vorteilhafterweise mit einer solchen Krümmung versehen.If the can 13 has a circular-cylindrical side wall, as shown in FIG. 1, a curved rod 28 is advantageously used, in which the radius of curvature is equal to the radius of the cylindrical side wall. In this way a clean contact of the rod 28 with the can 13 is obtained. The contact member 27 is also advantageously provided with such a curvature.
