Abstract
Description
Die Erfindung betrifft einen Unterdruckkanal für Faserbündelungseinrichtungen einer Spinnmaschine, mit einem mehreren Spinnstellen zuordenbaren rohrförmigen Grundkörper, dessen Außenkontur pro Spinnstelle für ein luftdurchlässiges Transportband eine erste Gleitfläche enthält, die einen im Wesentlichen in Umfangsrichtung des Grundkörpers verlaufenden Saugschlitz aufweist, sowie mit einer am Ende des Saugschlitzes befindlichen Armierung, die eine zweite, die erste Gleitfläche verlängernde Gleitfläche enthält.The The invention relates to a vacuum channel for fiber bundling devices Spinning machine, with a plurality of spinning stations assignable tubular body whose Outer contour per Spinning station for an air-permeable Conveyor belt a first sliding surface contains the one extending substantially in the circumferential direction of the body Suction slot has, as well as with one at the end of the suction slot located reinforcement which contains a second, the first sliding surface extending sliding surface.
Faserbündelungseinrichtungen dienen dem Zweck, einen verstreckten, noch drehungsfreien Stapelfaserverband durch seitliches Zusammenfassen seiner Fasern so weit zu bündeln oder zu verdichten, dass diesem Stapelfaserverband nach Durchlaufen einer Klemmstelle seine Spinndrehung erteilt werden kann, ohne dass ein allzu breites Spinndreieck entsteht. Derartige Spinndreiecke entstehen dadurch, dass ein Stapelfaserverband mit einer relativen Breite aus einer Klemmstelle austritt und dann zu einem Faden relativ kleinen Durchmessers zusammengedreht wird. Ein solches Spinndreieck enthält in der Regel Randfasern, die nicht ordnungsgemäß in den entstehenden Faden eingebunden werden und somit wenig oder nichts zur Festigkeit des ersponnenen Fadens beitragen. Wenn aber vor einer Drallerteilung der Stapelfaserverband in einer Faserbündelungseinrichtung verdichtet wird, wird das Spinndreieck kleiner und der ersponnene Faden insgesamt fester, gleichförmiger und weniger haarig.Fiber bundling means serve the purpose of a stretched, still rotation-free staple fiber strand by bundling its fibers together as far as possible or to compact that staple fiber strand after passing through a Clamping his spinning spin can be issued without a too wide spider triangle arises. Such spin triangles arise in that a staple fiber bandage having a relative width emerges from a nip and then to a thread relatively small Diameter is twisted together. Such a spin triangle usually contains Edge fibers that are not properly in the resulting thread be integrated and thus little or nothing to the strength of the spun thread. But if before a twist distribution of Staple fiber bundle compacted in a fiber bundling device becomes, the spinning triangle becomes smaller and the spun thread in total firmer, more uniform and less hairy.

Faserbündelungseinrichtungen weisen

eingangs genannten Art ist durch die
Die in den Grundkörper eingesetzte Armierung, die sich über die Arbeitsbreite des Transportbandes erstreckt, hat in erster Linie die Aufgabe, im Bereich der erwähnten Klemmstelle den Verschleiß zu verringern, der durch den Andruck der Klemmwalze an den Unterdruckkanal entsteht. Da die erste und die zweite Gleitfläche hintereinander angeordnet sind, ist die Armierung des bekannten Unterdruckkanals in eine Aussparung des Grundkörpers bündig eingesetzt. Es hat sich jedoch gezeigt, dass es für die Herstellung des Grundkörpers und der Armierung unabdingbar ist, sehr enge Toleranzen einzuhalten. Dies führt zu einer Verteuerung der einzelnen Faserbündelungseinrichtungen.The into the main body used reinforcement, which is about the working width of the conveyor belt has, in the first place the task in the area of mentioned Clamp the wear too reduce, by the pressure of the pinch roller to the vacuum channel arises. Since the first and second sliding surfaces are arranged one behind the other, is the reinforcement of the known vacuum channel in a recess of the basic body used flush. However, it has been shown that it is necessary for the manufacture of the main body and Reinforcement is essential to comply with very tight tolerances. This leads to an increase in the cost of the individual fiber bundling devices.

Der Erfindung liegt die Aufgabe zu Grunde, einen Unterdruckkanal der eingangs genannten Art im Hinblick auf Toleranzen zu vereinfachen und insgesamt kostengünstiger zu gestalten.Of the Invention is based on the object, a vacuum channel of to simplify the aforementioned type with respect to tolerances and overall more cost effective to design.
Diese Aufgabe wird dadurch gelöst, dass die Armierung als mehreren benachbarten Saugschlitzen gemeinsam zugeordnete Gleitleiste ausgebildet ist. Dies führt zu einer vereinfachten Fertigung und insgesamt zu einer toleranzunabhängigeren Armierung.These Task is solved by that the reinforcement is common as several adjacent suction slots associated slide bar is formed. This leads to a simplified Production and overall to a tolerance-independent reinforcement.
Vorteilhaft weist der Grundkörper eine sich über seine gesamte Länge erstreckende schwalbenschwanzförmige Nut auf, in welche wenigstens eine mit entsprechend geformten Anlageflächen versehene Gleitleiste eingeschoben ist. Eine solche Gleitleiste kann vorzugsweise aus Keramik oder Kunststoff bestehen und am Grundkörper austauschbar angeordnet sein. Dabei ist es möglich, pro Grundkörper des Unterdruckkanals eine einzige Gleitleiste vorzusehen oder pro Grundkörper mehrere gleichartige Gleitleisten aneinander zu reihen.Advantageous indicates the basic body one over his entire length extending dovetailed Groove, in which at least one provided with correspondingly shaped bearing surfaces Sliding strip is inserted. Such a sliding strip may preferably made of ceramic or plastic and interchangeable on the body be arranged. It is possible per basic body of the Vacuum channel to provide a single sliding strip or more per body to line similar sliding strips together.
Die in die schwalbenschwanzförmige Nut eingeschobene Gleitleiste wird zweckmäßig durch den Grundkörper stirnseitig verschließende Deckel fixiert. Auch dies führt zu einer Verringerung der Toleranzen.The in the dovetail Grooved sliding strip is expedient by the body frontally closes Cover fixed. This too leads to a reduction of the tolerances.
Die Gleitleiste kann unmittelbar an die einzelnen Saugschlitze angrenzen oder zum Ende des jeweiligen Saugschlitzes einen kleinen Abstand aufweisen. Damit das Transportband satt aufliegt, ist die Gleitleiste an ihrer Gleitfläche vorteilhaft leicht konvex gekrümmt.The Sliding strip can directly adjoin the individual suction slots or to the end of the respective suction slot a small distance exhibit. So that the conveyor belt rests tired, is the slide bar on its sliding surface advantageous slightly convex curved.
Die Erfindung betrifft auch eine Armierung für einen Unterdruckkanal für Faserbündelungseinrichtungen einer Spinnmaschine, mit einer einem Transportband zuordenbaren Gleitfläche sowie mit Anlageflächen zum Einsetzen in einen Unterdruckkanal und ist dadurch gekennzeichnet, dass die Anlageflächen zum Einschieben in eine schwalbenschwanzförmige Nut ausgebildet sind. Damit wird auch für die Armierung gesondert Schutz beansprucht.The The invention also relates to a reinforcement for a vacuum duct for fiber bundling devices a spinning machine, with a transport belt assignable sliding surface as well as with contact surfaces for insertion into a vacuum channel and is characterized that the contact surfaces for Insertion into a dovetail-shaped groove are formed. This will also for the armor separately claimed protection.
