Description
Die Erfindung bezieht sich auf eine Absaugvorrichtung für die Verdichtungsluft von zwei auswechselbaren Saugeinheiten an einem Zwillingsstreckwerk einer Spinnmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a suction device for the compression air of two interchangeable suction units on a twin drafting system of a spinning machine according to the preamble of
Aus der Praxis sind verschiedene Ausführungen bekannt, wobei auswechselbare Saugeinheiten an Verdichtungselementen, wie z. B. an perforierten Saugtrommeln eingesetzt werden. Die Verdichtungselemente weisen in der Regel einen Saugschlitz auf, der einerseits mit einem Saugkanal in Verbindung steht und andererseits einer, mit Perforationen versehenen Stelle der Saugtrommel gegenüberstehen. Die Saugkanäle der Saugtrommeln stehen im montierten Zustand mit einem Absaugrohr in Verbindung, über welches die Saugluft zu einer zentralen Absaugung geführt wird, die mit einer Unterdruckquelle verbunden ist.From practice various designs are known, with interchangeable suction units of compression elements, such. B. be used on perforated suction drums. As a rule, the compression elements have a suction slot, which on the one hand communicates with a suction channel and, on the other hand, faces a point of the suction drum provided with perforations. The suction channels of the suction drums are in the assembled state with a suction pipe in connection, via which the suction air is fed to a central suction, which is connected to a vacuum source.
Aus der
Um die oben beschriebene Ausführung zu verbessern wurde in der
Die Erfindung stellt sich nunmehr die Aufgabe die vorhandenen Nachteile bekannter Lösungen zu vermeiden und eine einfach zu bedienende Absaugvorrichtung vorzuschlagen, bei welcher keine zusätzlichen Dichtelemente im Bereich der Kupplungsstellen benötigt werden und eine optimale Luftführung innerhalb der Absaugvorrichtung gewährleistet wird.The invention now has the task of avoiding the existing disadvantages of known solutions and to propose an easy-to-use suction device, in which no additional sealing elements in the region of the coupling points are required and an optimal air flow is ensured within the suction device.
Diese Aufgabe wird dadurch gelöst, indem vorgeschlagen wird, dass die Ausgangsöffnungen der Saugeinheiten jeweils einen rechteckförmig umlaufenden Flansch mit einer ebenen Anschlagfläche aufweisen, welche an einer gemeinsamen Kupplungsstelle nebeneinander auf einer umlaufenden, ebenen Anschlagfläche einer gemeinsamen, rechteckförmig ausgebildeten Öffnung des Absaugrohres aufliegen, wobei die Flansche mit den Ausgangsöffnungen der Saugeinheiten die Öffnung des Absaugrohres vollständig überdecken und über das Haltemittel mit einer Druckkraft auf der Anschlagfläche gehalten werden. Der Begriff "umlaufende, ebene Anschlagfläche" bedeutet, dass die rechteckförmige Öffnung von einer in sich geschlossenen Fläche umgeben ist. Über die ebenen (ebenfalls in sich geschlossenen) Flächen der Flansche, welche unter der Einwirkung einer Druckkraft auf der ebenen Anschlagfläche der Öffnung des Absaugrohres aufliegen, erhält man eine ausreichende Abdichtungsfläche im Bereich der Kupplungsstelle, welche die Absaugvorrichtung gegenüber der Umgebung abschottet. Ausserdem sind die Saugeinheiten leicht und schnell zu montieren und zu demontieren.This object is achieved by proposing that the outlet openings of the suction units each have a rectangular circumferential flange with a flat stop surface, which at a common coupling point next to each other on a circumferential, flat stop surface of a common, Rectangular formed opening of the suction tube, the flanges with the outlet openings of the suction completely cover the opening of the suction tube and are held on the holding means with a compressive force on the stop surface. The term "circumferential, flat stop surface" means that the rectangular opening is surrounded by a self-contained surface. On the flat (also self-contained) surfaces of the flanges, which rest under the action of a compressive force on the flat abutment surface of the opening of the suction, to obtain a sufficient sealing surface in the coupling point, which seals the suction against the environment. In addition, the suction units are easy and quick to assemble and disassemble.
Des Weiteren wird vorgeschlagen, dass das Saugelement in Bereich der Anschlagfläche und das Haltemittel derart ausgeformt sind, dass in der Verriegelungsstellung des Haltemittels die offen liegenden Aussenflächen der Flansche der Saugeinheiten überdeckt werden. Damit erhält man eine zusätzliche Abdichtfläche, welche sich geschlossen um den Umfang der nach aussen gerichteten Aussenflächen der Flansche erstreckt. D. h., sofern trotz der grossen Dichtfläche Undichtheiten in diesem Bereich auftreten würden, müssten Fasern, des sich in dem, in der Umgebung der Absaugvorrichtung befindlichen Faserfluges befinden, eine 90° Umlenkung im Bereich der Flansche durchführen, um in die Absaugvorrichtung zu gelangen. Damit erhält man eine zusätzliche Barriere, die das Eindringen von Verschmutzungen in den Bereich der Absaugvorrichtung an dieser Kupplungsstelle erschweren.Furthermore, it is proposed that the suction element in the region of the stop surface and the holding means are formed such that in the locking position of the holding means, the exposed outer surfaces of the flanges of the suction units are covered. This results in an additional sealing surface, which extends closed around the circumference of the outwardly directed outer surfaces of the flanges. In other words, if leaks occur in this area despite the large sealing surface, fibers which are located in the fiber fly located in the vicinity of the suction device would have to make a 90 ° deflection in the area of the flanges in order to reach the suction device , This results in an additional barrier that complicates the ingress of contaminants in the area of the suction device at this coupling point.
Um eine zusätzliche Abschottung an den Aussenflächen der Flansche zu erzielen, wird vorgeschlagen, dass das Saugelement, im Abstand zu den schmalen Seiten der rechteckigen Öffnung des Absaugrohres, seitlich angebrachte Stege aufweist, auf welchen zumindest teilweise, die in Richtung der Stege zeigenden Aussenflächen der nebeneinander liegenden Flansche der Saugeinheiten in Verriegelungsstellung anliegen.In order to achieve an additional foreclosure on the outer surfaces of the flanges, it is proposed that the suction element, at a distance from the narrow sides of the rectangular opening of the suction tube, laterally mounted webs, on which at least partially, the outer surfaces facing in the direction of the webs side by side lying flanges of the suction units in locking position.
Um eine Druckkraft auf die Flansche in ihrer montierten Position zu erzeugen, damit ihre Anschlagflächen sicher auf der Anschlagfläche der Öffnung des Absaugrohres aufliegen, wird weiter vorgeschlagen, dass die in der Verriegelungsstellung befindlichen und gegeneinander gerichteten Aussenflächen der Flansche der Saugeinheiten in Bezug auf ihre jeweilige Anschlagfläche unter einem Winkel kleiner als 90° verlaufen und das Halteelement einen Mittelsteg aufweist, der mit einer, im spitzen Winkel d auslaufenden freien Kante versehen ist, welche in Verriegelungsstellung zwischen die, gegeneinander gerichtete Aussenflächen der Flansche eingreift. Durch die keilförmige Ausbildung der gegeneinander gerichteten Aussenflächen der Flansche in montiertem Zustand im Zusammenwirken mit der keilförmig ausgebildeten Kante des Halteelementes wird einerseits eine Klemmkraft zwischen den beschriebenen Anschlagflächen erzeugt und andererseits wird durch die Keilwirkung über das Halteelement eine Kraft erzeugt, welche versucht, die beiden gegenüberliegenden Flächen der Flansche voneinander wegzudrücken. Dadurch werden die nach aussen gerichteten Aussenflächen der Flansche, welche ihren gegeneinander gerichteten Aussenflächen gegenüberstehen, gegen die seitlich an der Öffnung angebrachten Stege gedrückt. Damit werden die Flansche und somit die jeweils mit ihnen verbundene Saugeinheit fest in ihrer Position gegenüber den Saugtrommeln verriegelt und fixiert.In order to generate a compressive force on the flanges in their mounted position, so that their stop surfaces rest securely on the stop surface of the opening of the suction tube, it is further proposed that the located in the locking position and facing each other outer surfaces of the flanges of the suction units with respect to their respective stop surface extend at an angle less than 90 ° and the holding element has a central web, which terminates with a, at an acute angle d is provided free edge, which engages in the locking position between the oppositely directed outer surfaces of the flanges. Due to the wedge-shaped design of the oppositely directed outer surfaces of the flanges in the assembled state in cooperation with the wedge-shaped edge of the holding element, a clamping force between the abutment surfaces described is generated on the one hand and on the other hand, a force is generated by the wedge effect on the holding element, which tries to opposite the two Push surfaces of the flanges away from each other. Thereby, the outwardly directed outer surfaces of the flanges, which face their oppositely directed outer surfaces, pressed against the laterally attached to the opening webs. Thus, the flanges and thus the respectively associated with them suction unit are firmly locked in their position relative to the suction drums and fixed.
Weitere Vorteile der Erfindung werden in nachfolgenden Ausführungsbeispielen näher aufgezeigt und beschrieben.Further advantages of the invention will be shown and described in more detail in subsequent embodiments.

Dabei können Einzelantriebe, wie auch andere Antriebsformen (Zahnräder, Zahnriemen, usw.) eingesetzt werden. Über die angetriebenen Unterwalzen werden die Druckwalzen, bzw. deren Riemchen über Friktion angetrieben. Die Umfangsgeschwindigkeit der Walzenpaare 4 ist etwas höher als die Umfangsgeschwindigkeit der Walzenpaare 3, sodass das, der Streckwerkeinheit 2 zugeführte Fasergut in Form einer Lunte L zwischen dem Eingangswalzenpaar 3 und dem Mittenwalzenpaar 4 einem Vorverzug unterworfen wird. Der Hauptverzug des Fasergutes L entsteht zwischen dem Mittenwalzenpaar 4 und dem Ausgangswalzenpaar 5, wobei das Ausgangswalzenpaar 5 eine wesentlich höhere Umfangsgeschwindigkeit als das Mittelwalzenpaar 4 aufweist. Das Ausgangswalzenpaar 5 ist im vorliegenden Beispiel mit einer Verdichtungsvorrichtung W ausgestattet.The lower rollers of the roller pairs 3, 4, 5 are connected to a drive, not shown. In this case, individual drives, as well as other forms of drive (gears, timing belts, etc.) can be used.
