Die den Filtertowstreifen begleitende laminare Luftströmung verhindert Luftwirbel, so daß eine störungsfreie, bzw. homogene spezifische Towbehandlung in der Reckzone, der Entspannungszone und Raffzone gewährleistet ist. Die Luftströmung dient gleichzeitig als Transportmedium zum Entfernen von abgelösten bzw. lose haftenden Towfasern, so daß auch bei hohen Fördergeschwindigkeiten des Filtertowstreifens eine homogene Aufbereitung und Verteilung des Filtermaterials im Filterstrang erreicht wird. DE 198 11 014 A1 also describes a device for Manufacture of filter rods for rod-shaped articles of the tobacco processing industry in which the Filter tow strips along a stretching line, application line, Raff stretch, through one with in the conveying direction of the tow strip guided air flow Wind tunnel is passed through. The the Laminar air flow accompanying filter tow strips prevents air turbulence, so that a trouble-free or homogeneous specific tow treatment in the stretching zone, the Relaxation zone and gathering zone is guaranteed.

Ausgehend von dem Stand der Technik ist es Aufgabe der Erfindung, die Verunreinigung der Vorrichtung durch Staubpartikel, insbesondere Towfasern, zu verringern und gleichzeitig den Betrieb einer derartigen Vorrichtung wirtschaftlicher zu gestalten.Based on the state of the art, it is the task of Invention, contamination of the device by To reduce dust particles, especially tow fibers, and at the same time the operation of such a device to make it more economical.

Die Aufgabe wird bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, daß wenigstens eine Absaugeinrichtung vorgesehen ist, die saugseitig an der Förderstrecke des Streifens angeordnet ist und druckseitig mit dem Druckluftorgan verbunden ist. Ein Druckluftorgan für ein Streifen stellt bspw. eine Ausbreiterdüse dar, die von einer Druckluftquelle mit Druckluft versorgt wird. Durch die Rückführung von Saugluft als Blasluft zu dem Druckluftorgan kann auf die Druckluftquelle verzichtet werden. Gleichzeitig werden Verunreinigungen z.B. im Bereich der Reckzone vermieden, da die Towfasern aus diesem Bereich weggeführt werden. Selbstverständlich können erfindungsgemäß auch andere Druckluftorgane als eine Ausbreiterdüse von der Absaugeinrichtung mit Luft versorgt werden.The task is at the beginning of a device mentioned type in that at least one Suction device is provided on the suction side of the Conveyor path of the strip is arranged and pressure side is connected to the compressed air element. A compressed air organ for a strip, for example Spreader nozzle with a compressed air source Compressed air is supplied. By returning from Suction air as blown air to the compressed air organ can on the Compressed air source can be dispensed with. Be at the same time Impurities e.g. avoided in the area of the stretching zone, because the tow fibers are led away from this area.

Zur Verringerung von Verunreinigungen ist es vorteilhaft, wenn die Absaugeinrichtung, insbesondere saugseitig, wenigstens eine Filtereinrichtung und/oder eine Reinigungseinrichtung für die Saugluft aufweist. Durch eine Filtereinrichtung bspw. können dem Luftstrom grobe und feine Staubpartikel entzogen werden, so daß saubere Blasluft an die Druckluftorgane weitergegeben werden kann. Dadurch werden die Maschine und die Umwelt sauber gehalten, da z.B. feine Towfasern zurückgehalten und nicht in die Umgebungsluft geblasen werden.To reduce contamination, it is advantageous if the suction device, especially on the suction side, at least one filter device and / or one Has cleaning device for the suction air. By a filter device, for example, can rough the air flow and fine dust particles are removed, so that clean Blown air are passed on to the compressed air organs can. This makes the machine and the environment clean held because e.g. fine tow fibers retained and not be blown into the ambient air.

In einer Weiterbildung der Erfindung weist die Absaugeinrichtung, insbesondere druckseitig, wenigstens eine, vorzugsweise steuerbare, Drosseleinrichtung auf, um Blasluft an die Druckluftverbraucher mit einem einstellbaren Druck zu liefern.In a development of the invention, the suction device has in particular on the pressure side, at least one, preferably controllable, throttle device to Blown air to the compressed air consumer with an adjustable To deliver pressure.

In einer Weiterbildung der Erfindung ist vorteilhafterweise wenigstens eine Druckmeßeinrichtung saugseitig und/oder druckseitig mit der Regeleinrichtung und/oder Steuereinrichtung verbunden. Durch die Erfassung des Unterdrucks auf der Saugseite und/oder durch die Druckmessungen an den Druckluftorganen, kann die Absaugeinrichtung entsprechend geregelt und/oder gesteuert werden. Außerdem kann somit ein Betrieb der Vorrichtung unter Berücksichtigung einer wirtschaftlichen Betriebsweise optimiert werden.In a development of the invention is advantageous at least one pressure measuring device on the suction side and / or pressure side with the control device and / or Control device connected. By capturing the Vacuum on the suction side and / or by the pressure measurements on the compressed air organs, the suction device regulated and / or controlled accordingly become.

Besonders vorteilhaft ist es, wenn die Regeleinrichtung und/oder die Steuereinrichtung mittels einer Maschinenzentrale, insbesondere speicherprogrammierbare Steuerung (SPS), ausgebildet ist. In der Maschinenzentrale werden sämtliche Prozesse an einem Maschinenaggregat bzw. in der gesamten Maschine zusammenfassend gesteuert und/oder geregelt. Als geeignete Steuerung solcher komplexen Maschinen hat sich die speicherprogrammierbare Steuerung bewährt.It is particularly advantageous if the control device and / or the control device by means of a machine center, in particular programmable logic controller (SPS) is trained. In the machine center all processes on one machine unit or in the entire machine is controlled and / or summarized regulated. As a suitable control of such complex The programmable logic controller has become machines proven.

Die erfindungsgemäße Vorrichtung wird vorteilhafterweise dadurch weitergebildet, daß die Saugseite der Absaugeinrichtung in einer Reckzone einer Reckstrecke der Förderstrecke angeordnet ist. Hierdurch kann eine Vorrichtung, wie sie aus DE 198 11 014 A1 bekannt ist, verbessert werden, da bereits eine Absaugeinrichtung vorhanden ist. Diese Absaugeinrichtung kann insgesamt noch wirtschaftlicher betrieben werden. Zudem kann auf den Einbau von Druckluftquellen für die Druckluftorgane vollständig verzichtet werden. In einer Alternative ist die Saugseite der Absaugeinrichtung am Ende eines Streckenabschnitts der Förderstrecke, insbesondere Reckstrecke und/oder Auftragsstrecke und/oder Raffstrecke, angeordnet.The device according to the invention is advantageously further developed in that the suction side of the suction device in a stretching zone of a stretching section of the Conveyor line is arranged.

In addition, on the installation of compressed air sources for the compressed air organs be completely dispensed with. In an alternative is the suction side of the suction device at the end of a Section of the conveyor line, in particular Stretching section and / or application section and / or gathering section, arranged.

Ferner besteht die Lösung beim Verfahren der eingangs genannten Art darin, daß Luft an der Förderstrecke abgesaugt wird und an das Druckluftorgan geliefert wird. Eine Absaugeinrichtung kann daher gleichzeitig die Funktionen der Luftansaugung und der Luftbeförderung verwirklichen. Daneben ergeben sich auch konstruktive Verbesserungen, da auf eine Druckluftquelle für das Druckluftorgan verzichtet werden kann.There is also the solution to the method of the beginning mentioned type in that air on the conveyor line is suctioned off and delivered to the compressed air organ. A suction device can therefore simultaneously Air intake and air transport functions realize. In addition, there are also constructive ones Improvements because of a compressed air source for the Compressed air element can be dispensed with.

Weiterhin wird vorteilhafterweise die Luft druckseitig, vorzugsweise mittels einer, insbesondere steuerbaren, Drosseleinrichtung, gedrosselt.Furthermore, the air is advantageously on the pressure side, preferably by means of a, in particular controllable, Throttle device, throttled.

Darüber hinaus ist es von Vorteil, wenn die Strömung der Luft geregelt und/oder gesteuert wird.In addition, it is advantageous if the flow of the Air is regulated and / or controlled.

Ein optimaler Betrieb läßt sich erreichen, wenn die Luftströmung in Abhängigkeit des Luftdrucks auf der Saugseite und/oder der Druckseite geregelt und/oder gesteuert wird. Optimal operation can be achieved if the Air flow depending on the air pressure on the Suction side and / or the pressure side regulated and / or is controlled.

Im Falle, daß zuviel Blas- oder Druckluft während des Betriebs entsteht, ist es von Vorteil, wenn, insbesondere überschüssige, Luft auf der Druckseite an die Atmosphäre abgegeben wird. Neben einer Druckentlastung findet auch eine Reinigung der Umgebungsluft hierdurch statt.In the event that too much blowing or compressed air during the Operating arises, it is advantageous if, in particular excess air on the pressure side to the Atmosphere is released. In addition to pressure relief this also finds a cleaning of the ambient air instead of.

Weiterhin wird bevorzugt die Luft in einer Reckzone einer Reckstrecke der Förderstrecke abgesaugt.The air in a stretching zone is also preferred sucked a stretch of the conveyor line.

Alternativ wird vorteilhafterweise die Luft am Ende eines Streckenabschnitts der Förderstrecke, insbesondere Reckstrecke und/oder Auftragsstrecke und/oder Raffstrecke, abgesaugt, so daß bestehende Absaugeinrichtungen genutzt werden können.Alternatively, the air will advantageously end up a section of the conveyor line, in particular Stretching section and / or application section and / or gathering section, suctioned off, so that existing suction devices can be used.

Aufgrund von geeigneten Hebelverhältnissen von Griff 77 und Hebelarm 79 kann mit einer geringen Kraft der Abstand zwischen den Magneten 75 und 76 vergrößert werden, wodurch auch die magnetischen Kräfte herabgesetzt werden. Der Griff 77 ist als Hebel ausgeführt, so daß das Trennen der Magneten 75, 76 zusätzlich mechanisch unterstützt wird. Dadurch wird wesentlich weniger Kraft zum Öffnen des Deckels 72 benötigt, ohne die Zuhaltefunktion der Düse 16 zu beeinträchtigen. Due to suitable lever ratios of handle 77 and lever arm 79 can with a small force Distance between magnets 75 and 76 increased are reduced, which also reduces the magnetic forces become. The handle 77 is designed as a lever, so that the separation of the magnets 75, 76 additionally mechanically is supported. This will make much less Force needed to open the lid 72 without the To impair the locking function of the nozzle 16.

Außerdem ist es günstig, wenn der Abstand des Drehpunkts 78 vom Scharniergelenk 73 größer ist als der Abstand zwischen den Magneten 76 und dem Scharniergelenk 73. Hierdurch entstehen bessere Hebelverhältnisse, so daß durch diese Maßnahme weniger Kraft zum Öffnen der Düse 16 erforderlich ist.It is also beneficial if the distance of the fulcrum 78 of the hinge joint 73 is greater than the distance between the magnets 76 and the hinge joint 73. This creates better leverage, so that this means less force to open the nozzle 16 is required.

Durch den Hebelgriff 77, den Drehpunkt 78 und den Hebelarm 79 sind mechanische Mittel vorhanden, die das Öffnen der Ausbreiterdüse 16 und das Einlegen eines Filtertowstreifens erleichtern. By lever handle 77, pivot point 78 and Lever arm 79 mechanical means are available that the Open the spreader nozzle 16 and insert one Lighten the filter tow strip.
