Abstract
Description
Die Erfindung betrifft eine Offenend-Spinnvorrichtung mit einem einen Rotorschaft aufweisenden Spinnrotor, der an seinem Rotorschaft durch einen Tangentialriemen antreibbar ist, mit einem unter Unterdruck stehenden Rotorgehäuse, das über einen Unterdruckkanal mit einer Unterdruckquelle verbindbar ist, und mit einer an einer Schwinge befestigten Andruckrolle zum Andrücken des Tangentialriemens an den Rotorschaft, wobei die Schwinge schwenkbar auf einer in der Offenend-Spinnvorrichtung befestigten Achse gelagert ist.The The invention relates to an open-end spinning device having a Rotor shaft having spinning rotor, which at its rotor shaft through a tangential belt is drivable, with one under negative pressure standing rotor housing, the above a vacuum channel is connectable to a vacuum source, and with a pressure roller attached to a rocker for pressing the Tangential belt to the rotor shaft, the rocker pivotally a mounted in the open-end spinning device axis stored is.
Eine
Offenend-Spinnvorrichtung mit einer an einer Schwinge befestigten
Andruckrolle ist durch die
Bei der bekannten Ausführung ist nachteilig, dass für die Unterbringung des Unterdruckkanals neben der schwenkbaren Schwinge sehr viel Bauraum in der Offenend-Spinnvorrichtung benötigt wird.at the known design is disadvantageous that for the placement of the vacuum duct next to the pivoting rocker a lot of space in the open-end spinning device is needed.
Der Erfindung liegt die Aufgabe zu Grunde, die Bauraum-Ausnutzung in der Offenend-Spinnvorrichtung zu optimieren.Of the Invention is based on the object, the space utilization in to optimize the open-end spinning device.
Die Aufgabe wird dadurch gelöst, dass ein Teil des Unterdruckkanals im Innern der Achse verläuft, auf der die Schwinge für die Andruckrolle gelagert ist.The Task is solved by that a part of the vacuum channel runs in the interior of the axis, on the swingarm for the pressure roller is mounted.
Durch einen im Innern der Achse verlaufenden Unterdruckkanal kann der vorher zusätzlich durch die Offenend-Spinnvorrichtung verlaufende Unterdruckkanal entfallen und es wird insgesamt Bauraum eingespart. Es ist zwar vorteilhaft, den Durchmesser der Achse zu vergrößern, um im Innern genügend freien Querschnitt für einen Unterdruckkanal zu schaffen, trotzdem wird in der Summe aber noch Bauraum eingespart. Die gesamte Offenend-Spinnvorrichtung wird in ihrem Gesamtaufbau durch diese Doppelfunktion der Achse wesentlich vereinfacht. Es sind insgesamt weniger Bauteile mit Ecken und Kanten vorhanden, an denen sich überall Schmutz und Staub anlagern kann. Neben der geringeren Verschmutzung ist diese Offenend-Spinnvorrichtung auch einfacher zu reinigen.By a running in the interior of the axis vacuum channel, the through in addition the open-end spinning device extending vacuum channel omitted and overall space is saved. While it is advantageous to increase the diameter of the axis, in order to free enough inside Cross section for a vacuum channel to create, but still in the sum Saves space. The entire open-end spinning device is through in its overall construction This double function of the axle considerably simplified. There are in total There are fewer components with corners and edges, where dirt is everywhere and can accumulate dust. Besides the less pollution is this open-end spinning device also easier to clean.
In Ausgestaltung der Erfindung ist es vorteilhaft, wenn wenigstens eine durch Wegschwenken der Andruckrolle von dem Tangentialriemen öffenbare Öffnung in dem Unterdruckkanal enthalten ist, durch die zusätzliche Luft in den Unterdruckkanal einsaugbar ist. Wenn der Spinnvorgang unterbrochen ist, und die Andruckrolle vom Tangentialriemen abgehoben ist, bewirkt dieser zusätzliche Luftstrom eine Verringerung des Unterdruckes im Rotorgehäuse, so dass ein das Rotorgehäuse verschließendes Deckelelement leichter geöffnet werden kann. Vorzugsweise ist über die Öffnung im Unterdruckkanal ein weiterer Kanal mit Unterdruck beaufschlagbar, der mit seiner Mündung einer zu reinigenden Stelle der Offenend-Spinnvorrichtung zugeordnet ist. Der zusätzliche Luftstrom kann so zum Reinigen von verschmutzten Bereichen der Offenend-Spinnvorrichtung benutzt werden. Diese Stelle kann beispielsweise der Bereich des Axiallagers des Spinnrotors sein.In Embodiment of the invention, it is advantageous if at least an openable by pivoting away of the pressure roller of the tangential opening in the vacuum channel is included, sucked by the additional air in the vacuum channel is. When spinning is interrupted and the pinch roller lifted off the tangential belt, this causes additional Air flow a reduction of the negative pressure in the rotor housing, so that one the rotor housing closing lid element easier to open can be. Preferably is about the opening in the vacuum channel another channel with negative pressure can be acted upon, the with his mouth associated with a point to be cleaned the open-end spinning device is. The additional Air flow can thus be used to clean soiled areas of the open-end spinning device to be used. For example, this area may be the area of Be axial bearings of the spinning rotor.
Eine Vergrößerung des Außendurchmessers der Achse hat den Vorteil, dass die Lagerung der Schwinge verbessert wird. Die Achsen in den bekannten Offenend-Spinnvorrichtungen waren üblicherweise als Bolzen mit einem Durchmesser in der Größenordnung von 15 mm gestaltet. Es ist vorteilhaft, wenn die Achse einen Außendurchmesser von wenigstens 20 mm, insbesondere von etwa 25 mm, hat. Die in der Lagerung auftretenden Reibkräfte bewirken bei vergrößertem Außendurchmesser ein größeres Reibmoment auf die Schwinge. Dieses Reibmoment hat einen positiven Effekt bei Schwingungsbewegungen der Andruckrolle, die durch den schnelllaufenden Tangentialriemen unweigerlich auftreten. Das vergrößerte Reibmoment wirkt dämpfend und führt zu einer Verringerung der Schwingungsamplitude der Andruckrolle.A Magnification of the Outside diameter of the Axis has the advantage that the bearing of the rocker improves becomes. The axes in the known open-end spinning devices were conventional designed as a bolt with a diameter in the order of 15 mm. It is advantageous if the axis has an outer diameter of at least 20 mm, in particular of about 25 mm. The occurring in storage friction effect at increased outside diameter a larger friction torque on the swingarm. This friction torque has a positive effect Vibration movements of the pinch roller caused by the high-speed Tangential belts inevitably occur. The increased friction torque has a dampening effect and leads to a reduction in the vibration amplitude of the pressure roller.
In weiterer Ausgestaltung kann vorgesehen sein, die Dämpfung der Schwinge durch zusätzliche Elemente noch weiter zu erhöhen. Es kann vorgesehen sein, im Bereich der Lagerung der Schwinge zusätzliche definierte Reibkräfte aufzubringen, die eine Schwenkbewegung der Schwinge bremsen und dadurch dämpfend wirken. Dies könnte durch federbelastete Reibelemente erfolgen, oder auch durch Fluide mit einer sehr hohen Viskosität, welche direkt im Spalt zwischen Schwinge und Achse wirken.In Another embodiment may be provided, the damping of Swing arm by additional elements even further increase. It can be provided in the area of storage of the rocker additional defined friction forces apply, which brake a pivoting movement of the rocker and thereby dampening Act. this could done by spring-loaded friction, or by fluids with a very high viscosity, which act directly in the gap between rocker and axle.
