Description

Die Erfindung bezieht sich auf ein Streckwerk für eine Spinnereimaschine, mit einer pneumatischen Verdichtungseinrichtung, welche ein Transportmittel mit Perforationen und eine über eine Saugöffnung damit verbundene Absaugvorrichtung aufweist, die sich auf der einem Faserverband abgewandten Seite des Transportmittels zwischen mindestens einer Ausgangswalze und einer Liefervorrichtung erstreckt, wobei im Wirkungsbereich der Saugöffnung, der Absaugvorrichtung gegenüberliegend, ein Abschirmelement angeordnet ist.The invention relates to a drafting system for a spinning machine, with a pneumatic compression device, which a means of transport Perforations and a suction device connected to it via a suction opening has, which on the side facing away from a fiber structure Transport means between at least one output roller and a delivery device extends, in the effective area of the suction opening, the suction device opposite, a shielding element is arranged.

Zum Stand der Technik zählt bereits eine derartige Konstruktion (DE 198 15 325 A1), bei welcher zwischen einem Streckwerk und einer Drehungserteilungs- und Aufwindevorrichtung ein perforiertes Verdichtungselement unterhalb eines Schirmes angeordnet ist. Bei dieser Konstruktion ist die Ausgangsunterwalze als perforierte Saugwalze ausgebildet, wobei die vorgenannte Schirm umlenkende Funktionen hat und die Luftströmung derart beeinflussen soll, daß diese von beiden Seiten auf den Faserverband einwirkt und dadurch die Gamqualität verbessert. Die Abstände dieser Schirme zu den Absaugunterwalzen müssen an jedem Spinnstellenpaar einzeln eingestellt und infolge der Beweglichkeit der Belastungsträger des Streckwerks regelmäßig kontrolliert werden.Such a construction already belongs to the prior art (DE 198 15 325 A1), in which between a drafting system and a rotation and winding device a perforated compression element below a screen is arranged. In this construction, the output bottom roller is formed as a perforated suction roll, the aforementioned umbrella has deflecting functions and should influence the air flow in such a way that this affects the fiber structure from both sides and thereby the quality of the yarn improved. The distances of these screens to the suction lower rollers must be set individually on each pair of spinning units and as a result of their mobility the load carrier of the drafting system is checked regularly.

Entsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, bei einem pneumatischen Verdichtungsstreckwerk der eingangs genannten Art den Aufwand zur Einstellung und Justierung von Abschirmelementen zu verringern, wobei gleichzeitig der Energieverbrauch zur Erzeugung des Unterdrucks durch Optimierung der Saugluftströmung gesenkt werden soll, ohne hierbei jedoch die Bedienbarkeit des Streckwerks zu erschweren. Accordingly, the present invention is based on the object pneumatic compression drafting system of the type mentioned Reduce the effort for setting and adjusting shielding elements, at the same time the energy consumption for generating the negative pressure through Optimization of the suction air flow should be reduced, but without this To make it difficult to operate the drafting system.

Diese Aufgabe wird dadurch gelöst, daß sich das als durchgehendes Profil ausgebildete Abschirmelement über mehrere Spinnstellen erstreckt und unterhalb der Streckfeldebene am Maschinenrahmen befestigt ist. Erfindungsgemäß werden also die Abschirmelemente mehrerer Absaugvorrichtungen zusammengefaßt, wobei Abschirmelemente sektionsweise für mehr als vier Spinnstellen zusammengefaßt sein können. Beispielsweise können vier, sechs, acht, zehn und zwölf Spinnstellen einem Abschirmelement zugeordnet werden. Diese Abschirmelemente können in weiterer Ausgestaltung der Erfindung als durchgehendes Profil mit T- oder V-förmigem Querschnitt oder polygonal ausgeführt sein, wobei sich dieses Profil vorteilhafter Weise unterhalb der Streckfeldebene befindet. Diese Anordnung erlaubt im Gegensatz zum Stand der Technik eine großflächige Ausbildung der Abschirmelemente, ohne die Bedienung des Streckwerks zu behindern.This object is achieved in that it is a continuous profile trained shielding element extends over several spinning positions and below the stretching field level is attached to the machine frame. According to the invention the shielding elements of several suction devices are thus combined, shielding elements section by section for more than four spinning positions can be summarized. For example, four, six, eight, ten and twelve spinning positions can be assigned to a shielding element. These shielding elements can in a further embodiment of the invention as a continuous Profile with T or V-shaped cross-section or polygonal be, this profile advantageously below the stretching field level located. In contrast to the prior art, this arrangement allows one large-scale training of the shielding elements without the operation of the Hinder drafting system.

In weiterer Ausgestaltung der Erfindung können die Enden des Profils am Maschinenrahmen, vorzugsweise an den Lagerstellen der Streckwerksunterwalzen befestigt werden. Hierbei können die Lagerstellen mit einer Aussparung versehen sein, in welche die Profilschiene, d. h. das Abschirmelement, von oben eingesetzt werden kann. Hierdurch sind keinerlei Einstellarbeiten für die Abschirmelemente erforderlich; ihre Position ist dadurch für alle Spinnstellen in dieser Sektion fixiert.In a further embodiment of the invention, the ends of the profile on the machine frame, preferably at the bearing points of the drafting roller be attached. The bearing points can be provided with a recess be in which the profile rail, d. H. the shielding element, inserted from above can be.

Beispielsweise besteht die Möglichkeit, daß bei balliger Kontur die vorgenannte Fläche des Abschirmelements hohl ausgebildet ist.According to another feature of the invention, the one opposite the suction opening Area of the respective shielding element of the contour of the tread be adapted to the means of transport. For example, there is the possibility that with a spherical contour, the aforementioned surface of the shielding element is hollow is trained.

Mit dieser Ausführungsform wird erreicht, daß die Saugluftströmung durch großflächige Abschirmelemente optimiert und der Energiebedarf zur Erzeugung des erforderlichen Unterdrucks gesenkt wird. Die Bedienbarkeit des Streckwerks, insbesondere das Einfädeln beim Anspinnen und das Durchführen von Reinigungsarbeiten, wird nicht behindert. With this embodiment it is achieved that the suction air flow through large-scale shielding elements optimized and the energy required for generation the required negative pressure is reduced. The operability of the drafting system, especially threading when piecing and performing Cleaning work is not hindered.
