Abstract

Die Erfindung bezieht sich auf eine Absaugvorrichtung für die Verdichtungsluft von zwei auswechselbaren Saugeinheiten (10, 10a) an einem Zwillingsstreckwerk (2z) einer Spinnmaschine (10, 10a) zur aerodynamischen Verdichtung von Fasergutes (V), das über jeweils eine Saugzone (Z) von, mit Perforationen (OE) versehenen, umlaufenden und einander gegenüberliegenden Verdichtungselementen (6, 6a) geführt wird, wobei die, dem jeweiligem Verdichtungselement zugeordnete Saugeinheit mit einer Saugöffnung (11, 11a) versehen ist, die mit einem in der jeweiligen Saugeinheit integrierten Saugkanal (12, 12a) verbunden ist und mit einem, den Saugeinheiten (10, 10a) zugeordnetem, ein Absaugrohr (22) aufweisendes Saugelement (15), durch das, die über die Saugeinheiten (10, 10a) abgesaugte Verdichtungsluft aus der Absaugvorrichtung abgegeben wird, wobei die Ausgangsöffnungen (O1, O2) des jeweiligen Saugkanals (12, 12a) einer Öffnung (O) des Absaugrohres in einer Kupplungsstelle (KS) gegenüber stehen und das Saugelement (15) Führungen (16) und Haltemittel (17) aufweist über welche die Saugeinheiten (10, 10a) gegenüber dem jeweiligen Verdichtungselement (6, 6a) gehalten und fixiert werden. Zu Vereinfachung und Verbesserung der Kupplungsstelle (KS) wird vorgeschlagen, dass die Ausgangsöffnungen (O1, O2) der Saugeinheiten (10, 10a) jeweils einen rechteckförmig umlaufenden Flansch (F1, F2) mit einer ebenen Anschlagfläche (A1, A2) aufweisen, welche an einer gemeinsamen Kupplungsstelle (KS) nebeneinander auf einer umlaufenden, ebenen Anschlagfläche (A) einer gemeinsamen, rechteckförmig ausgebildeten Öffnung (O) des Absaugrohres (22) aufliegen, wobei die Flansche (F1, F2) mit den Ausgangsöffnungen (O1, O2) der Saugeinheiten die Öffnung (O) des Absaugrohres (22) vollständig überdecken und über das Haltemittel (17) mit einer Druckkraft auf der Anschlagfläche (A) gehalten werden.

The invention relates to a suction device for the compression air of two replaceable suction units (10, 10a) on a twin drafting system (2z) of a spinning machine (10, 10a) for the aerodynamic compression of fiber material (V), each having a suction zone (Z) of , perforated (OE), circumferential and opposite compression elements (6, 6a) is guided, wherein the, associated with the respective compression element suction unit is provided with a suction opening (11, 11a) with a in the respective suction unit integrated suction channel ( 12, 12a) and with a, the suction units (10, 10a) associated, a suction tube (22) exhibiting suction element (15) through which is discharged via the suction units (10, 10a) compressed air discharged from the suction device, wherein the outlet openings (O1, O2) of the respective suction channel (12, 12a) of an opening (O) of the suction tube in a coupling point (KS) against ste hen and the suction member (15) guides (16) and holding means (17) via which the suction units (10, 10a) relative to the respective compression element (6, 6a) are held and fixed. To simplify and improve the coupling point (KS), it is proposed that the outlet openings (O1, O2) of the suction units (10, 10a) each have a rectangular circumferential flange (F1, F2) with a flat stop surface (A1, A2) a common coupling point (KS) side by side on a circumferential, flat stop surface (A) of a common, rectangular shaped opening (O) of the suction tube (22) rest, wherein the flanges (F1, F2) with the outlet openings (O1, O2) of the suction units Completely cover the opening (O) of the suction tube (22) and be held on the stop surface (A) by the holding means (17) with a compressive force.
