Description

Die Erfindung betrifft eine Vorrichtung an einer Spinnereivorbereitungsmaschine, z. B. Karde, Strecke o. dgl., zum Führen und Verdichten eines Faserverbandes aus mindestens einem Faserband, bei der hintereinander mindestens zwei trichterartige Leitelemente vorhanden sind, die hintereinander mehrere Wandflächen aufweisen, an denen der Faserverband entlanggleitet und zusammengeführt wird, wobei zwischen der Eintrittsöffnung und der Austrittsöffnung mindestens eine Wandzone vorhanden ist, in der der Faserverband über eine Öffnung mit der Außenluft in Verbindung steht.The invention relates to a device on a spinning preparation machine, for. B. card, stretch or the like, for guiding and compacting a fiber structure at least one sliver, in which at least two funnel-like in a row Guide elements are present, which have several wall surfaces in a row which the fiber structure slides along and is brought together, with between the inlet opening and the outlet opening have at least one wall zone in which the fiber structure is connected to the outside air via an opening stands.

Bei einer bekannten Vorrichtung (DE 33 27 574 C1) an einer Karde sind hintereinander zwischen einem Faserflor-Leitelement und einem Flortrichter zwei trichterartige Leitelemente angeordnet. Der von Quetschwalzen abgelieferte Faserflor wird durch das Faserflor-Leitelement zusammengefasst und gelangt durch eine Öffnung hindurch als vorverdichtetes Fasermaterial über die trichterartigen Leitelemente in den Flortrichter, aus dem es durch Abzugswalzen als Faserband abgezogen wird. Das eine trichterartige Leitelement ist nach unten gerichtet vollständig im Wandbereich geöffnet, während das andere trichterartige Leitelement nach oben gerichtet vollständig im Wandbereich geöffnet ist. Die beiden Leitelemente sind jeweils aus drei Wandflächen gebildet, von denen zwei einander gegenüberliegen. Etwa im rechten Winkel dazu sind die beiden einander gegenüberliegenden Wandflächen jeweils nach der einen Seite mit einer dritten Wandfläche verbunden, während die andere, dieser gegenüberliegenden Seite als durchgehende Öffnung ausgebildet ist, d. h. das Leitelement ist nach einer Seite hin offen. Die beiden einander gegenüberliegenden Wandflächen der Leitelemente sind - hintereinander gesehen - parallel zueinander ausgerichtet. Der Flortrichter weist allseits geschlossene Wandflächen auf. Bei dieser Vorrichtung stört, dass innerhalb eines jeden Leitelements die Verdichtung des Fasermaterials und der infolge der Verdichtung erfolgende Luftaustritt aus dem Fasermaterial unsymmetrisch sind. Auch in Bezug auf die beiden trichterartigen Leitelemente untereinander erfolgen die Verdichtung und der Luftaustritt unsymmetrisch zueinander.In a known device (DE 33 27 574 C1) on a card two in a row between a fiber pile guide and a pile funnel funnel-like guide elements arranged. The fiber web delivered by squeeze rollers is summarized by the fiber web guide element and passes through a Opening through as a pre-compressed fiber material over the funnel-like Guiding elements in the pile hopper, from which it is drawn off as sliver is subtracted. One funnel-like guide element is directed downwards fully open in the wall area while the other funnel-like baffle upwards is completely open in the wall area. The two Guide elements are each formed from three wall surfaces, two of which face each other opposite. The two are at right angles to each other opposite wall surfaces each on one side with a third Wall surface connected while the other, this opposite side as through opening is formed, d. H. the guide element is on one side open. The two opposite wall surfaces of the guide elements are - seen one behind the other - aligned parallel to each other. The pile funnel points closed wall surfaces on all sides. This device bothers that inside of each guide element the compression of the fiber material and the result of Compression of air emerging from the fiber material are asymmetrical. This also takes place with respect to the two funnel-like guide elements Compression and the air outlet asymmetrical to each other.

Nach der EP 0 412 256 A wird von zwei Quetschwalzen einer Karde ein hauchdünner, etwa 1 m breiter, unverdichteter Faserflor abgeliefert, der durch ein einziges Leitelement nach unten weitergeleitet wird. Das Leitelement besteht entsprechend einer Ausbildung aus lediglich zwei und gemäß einer weiteren Ausbildung aus vier einander gegenüberliegenden Wandelementen. Die vier Wandelemente sind nebeneinander und derart angeordnet, dass alle vier Wandelemente ohne Öffnung mit der Außenluft ein geschlossenes Gebilde darstellen. Bei keiner der beiden Ausführungsformen ist eine Anordnung von zwei hintereinander angeordneten Leitelementen vorgesehen. According to EP 0 412 256 A, one carding machine is used by two nip rollers wafer-thin, about 1 m wide, undensified fiber pile delivered by a only guiding element is passed down. The guiding element exists corresponding to a training of only two and according to another Formation from four opposite wall elements. The four Wall elements are arranged side by side and in such a way that all four Wall elements without opening with the outside air form a closed structure. In neither embodiment is an arrangement of two provided one behind the other guide elements.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, bei der -insbesondere die Verdichtung des Fasermaterials und der Luftaustritt aus dem Fasermaterial vergleichmäßigt sind.The invention is therefore based on the object of a device at the outset to create described type, which avoids the disadvantages mentioned, in which -in particular the compression of the fiber material and the air outlet from the Fiber material are evened out.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.This problem is solved by the characteristic features of Claim 1.

Die Vorrichtung besteht aus zwei und mehr Leitelementen, wobei erfindungsgemäß jedes einzelne Leitelement nur aus zwei gegenüberliegenden Wandelementen besteht, so daß die Verdichtung des Fasermaterials nur in einer Richtung erfolgt. Dadurch, daß jedes Wandelement nach beiden Seiten hin offen ist, kann die austretende Luft nach zwei Seiten hin in gleichem Umfang austreten. Auf diese Weise sind die Verdichtung und der Luftaustritt vergleichmäßigt. Dadurch, daß hintereinander jeweils benachbarte Wandelemente in einem Winkel, vorzugsweise 90°, zueinander angeordnet sind, wird einerseits die ungehinderte Breitenausdehnung des Fasermaterials nach den offenen Seiten hin gegenseitig begrenzt bzw. verhindert. Andererseits ist zugleich ermöglicht, daß durch die beidseitigen Öffnungen bei jedem einzelnen Leitelement die Verdichtungsluft ungehindert austreten kann. Weiterhin ist innerhalb eines jeden Leitelements die Reibung des Faserverbandes aus den Wandflächen reduziert; die Reibung an den seitlichen Wandflächen fehlt wegen der seitlichen Öffnungen völlig. In bezug auf ein Leitelement erfolgt die Verdichtung jeweils nur in eine Richtung, z. B. bei senkrechter Anordnung der Wandelemente in Querrichtung und bei dem unmittelbar benachbarten Leitelement aufgrund der waagerechten Anordnung der Wandelemente in senkrechter Richtung, d. h. Verdichtungsrichtung und Luftaustrittsvorrichtung wechseln einander ab. Durch die erfindungsgemäßen Maßnahmen, insbesondere aufgrund der Symmetrie der Vorrichtung, werden in vorteilhafter Weise die Verdichtung und der Luftaustritt miteinander kombiniert.The device consists of two and more guide elements, according to the invention each individual guide element consists of only two opposite wall elements, so that the compression of the fiber material takes place only in one direction. As a result of that each wall element is open on both sides, the escaping air can two sides emerge to the same extent. This is the compression and the air outlet is evened out. The fact that one behind the other Wall elements are arranged at an angle, preferably 90 °, to one another on the one hand the unhindered expansion of the fiber material after the open ones Mutually limited or prevented sides. On the other hand, it is also possible that through the double-sided openings in each guide element Compression air can escape unhindered. Furthermore, within everyone Guide element reduces the friction of the fiber structure from the wall surfaces; the Friction on the side wall surfaces is completely absent due to the side openings. In With respect to a guide element, the compression takes place in only one direction, for. B. at vertical arrangement of the wall elements in the transverse direction and in the immediate neighboring guide element due to the horizontal arrangement of the wall elements in vertical direction, d. H. Change compression direction and air outlet device each other. Through the measures according to the invention, in particular due to the Symmetry of the device, the compression and the advantageously Combined air outlet.

Zweckmäßig beträgt der Winkel 90°. Vorzugsweise ist zwischen zwei benachbarten Wandelementen ein Abstand vorhanden. Mit Vorteil weisen die Wandelemente einen kreisförmigen Querschnitt auf. Bevorzugt bestehen die Wandelemente aus einer Stange, einem Stab, Bolzen o. dgl. Zweckmäßig bestehen die Wandelemente aus einem verschleißfesten Werkstoff, z. B. gehärteter Stahl. Vorzugsweise sind die Wandelemente im Betrieb ortsfest. Mit Vorteil sind die Wandelemente zum Fördern des Fasermaterials drehbar angetrieben. Bevorzugt ist mindestens ein Wandelement eines Leitelements ortsveränderlich, z. B. verschiebbar, verschwenkbar o. dgl.. Zweckmäßig sind abwechselnd hintereinander ein Leitelement und ein Bandtrichter vorhanden. Vorzugsweise ist das Faserführungsorgan 10 am Ausgang einer Karde angeordnet. Mit Vorteil ist das Faserführungsorgan als Bandtrichter (34) am Ausgang einer Strecke angeordnet. Bevorzugt sind dem Faserführungsorgan zwei Abzugswalzen nachgeordnet. Zweckmäßig ist dem Faserführungsorgan mindestens ein Meßorgan für die Dicke des Faserverbandes zugeordnet.The angle is expediently 90 °. Is preferably between two neighboring ones There is a clearance between wall elements. The wall elements advantageously have one circular cross section. The wall elements preferably consist of a rod, a rod, bolt or the like. Advantageously, the wall elements consist of one wear-resistant material, e.g. B. hardened steel. Preferably, the Fixed wall elements in operation. The wall elements are advantageous for conveying the Fiber material rotatably driven.

Mit Hilfe dieses Regelsystems können Schwankungen im Querschnitt der eingespeisten Faserbänder 20 durch entsprechende Regelungen des Verzugsvorganges kompensiert bzw. eine Vergleichmäßigung des Faserbandes 35 erreicht werden.A central computer unit (41) (control and regulating device), for. B. Microcomputers with microprocessor, transmits a setting of the sol size for the control motor 36 to the controller 38. The measured variables of the two measuring elements 24 and 40 are during of the stretching process to the central computer unit 41. From the measurands of the inlet measuring element 24 and from the setpoint for the cross section of the emerging Sliver 35 is in the central computer unit 41, the setpoint for the Control motor 36 determines. The measured variables of the outlet measuring device 40 are used for Monitoring of the emerging sliver 35 (output sliver monitoring). With help this control system can fluctuate in the cross section of the fed Sliver 20 compensated by appropriate regulations of the drafting process or an equalization of the sliver 35 can be achieved.

Nach Fig. 3 besteht das Faserführungsorgan aus vier Leitelementen 41 bis 44, die jeweils aus zwei einander gegenüberliegenden Wandelementen 41a, 41b bis 44a, 44b gebildet sind. Die Wandelemente 41a bis 44b bestehen aus Stabmaterial, z. B. aus gehärtetem Stahl, mit kreisendem Querschnitt. Die gegenüberliegenden Wandelemente eines jeden Leitelements 41 bis 44 sind parallel zueinander angeordnet und weisen einen Abstand a, b, c und d zwischen den Wandelementen 44a, 44b, 43a, 43b, 42a, 42b bzw. 41a, 41b nehmen in Arbeitsrichtung A, d. h. in Laufrichtung des Fasermaterials, hin ab. Durch den Abstand, z. B. a zwischen den Wandelementen 41a, 41b, ist jedes Leitelement 41 bis 44 zu beiden Seiten hin offen. Jeweils hintereinander benachbart angeordnete Leitelemente 41 bis 44 sind in bezug auf die Längsachse der Vorrichtung, die im wesentlichen mit der Arbeitsrichtung A übereinstimmt, in einem Winkel von 90° zueinander angeordnet. 3, the fiber guide member consists of four guide elements 41 to 44, the each from two opposite wall elements 41a, 41b to 44a, 44b are formed. The wall elements 41a to 44b consist of rod material, e.g. B. from hardened steel, with circular cross-section. The opposite wall elements of each guide element 41 to 44 are arranged parallel to one another and have one Distance a, b, c and d between the wall elements 44a, 44b, 43a, 43b, 42a, 42b and 41a, 41b take in working direction A, i.e. H. in the direction of the fiber material. By the distance, e.g. B. a between the wall elements 41a, 41b, is each Guide element 41 to 44 open on both sides. Adjacent to each other arranged guide elements 41 to 44 are in relation to the longitudinal axis of the device, which essentially corresponds to the working direction A, at an angle of 90 ° arranged to each other.

Gemäß Fig. 4 sind die Wandelemente 41a, 41b, 43a, 43b drehbar gelagert und von einem endlos umlaufenden Antriebselement, z. B. Riemen 45, über eine Antriebseinrichtung, z. B. Motor 46, angetrieben. Die gebogenen Pfeile geben die Drehrichtung an. Die Wandelemente 42a, 42b, 44a, 44b sind in entsprechender (nicht dargestellter) Weise drehbar gelagert und angetrieben.4, the wall elements 41a, 41b, 43a, 43b are rotatably supported and by an endlessly rotating drive element, e.g. B. straps 45, over a Drive device, e.g. B. Motor 46 driven. The curved arrows indicate that Direction of rotation on. The wall elements 42a, 42b, 44a, 44b are in a corresponding (not shown) rotatably supported and driven.

Entsprechend Fig. 5a, 5b ist dem Ausgang des Faserführungsorgans ein angetriebenes Abzugswalzenpaar 11, 12 nachgeordnet, dessen Walzen in Richtung der gebogenen Pfeile drehbar sind. Jeweils zwischen zwei benachbarten Leitelementen 41 bis 44 ist jeweils ein Abstand e, f bzw. g vorhanden. Auf diese Weise kann Luft entweichen, die bei der Verdichtung aus dem Faserverband in Richtung der Pfeile austritt. Mit F ist das Fasermaterial bezeichnet.5a, 5b, the output of the fiber guide member is a driven one Subtraction roller pair 11, 12 downstream, the rollers in the direction of the curved Arrows are rotatable. Is between two adjacent guide elements 41 to 44 there is a distance e, f and g respectively. In this way air can escape emerges from the fiber structure in the direction of the arrows during compaction. With F it is Called fiber material.

Nach Fig. 6 besteht das Faserführungsorgan aus zwei Leitelementen 47, 48, die jeweils aus zwei einander gegenüberliegenden Wandelementen 47a, 47b bzw. 48a, 48b gebildet sind. Die Wandelemente 47a, 47b und 48a, 48b sind als Profilstücke ausgebildet. Das Wandelement 48b ist (auf nicht dargestellte) Weise in Richtung der Pfeile B, C und das Wandelement 47a ist (auf nicht dargestellte Weise) in Richtung der Pfeile D, E verschiebbar. Auf diese Weise werden die Spalte 49 und 50 zwischen den Wandelementen verändert, wodurch das Anspinnen (Einführen neuer Faserbänder F) ermöglicht bzw. erleichtert wird.6, the fiber guide member consists of two guide elements 47, 48, each formed from two opposite wall elements 47a, 47b and 48a, 48b are. The wall elements 47a, 47b and 48a, 48b are designed as profile pieces. The Wall element 48b is (in a manner not shown) in the direction of arrows B, C and that Wall element 47a is (in a manner not shown) in the direction of arrows D, E slidable. In this way, columns 49 and 50 between the Wall elements changed, whereby the piecing (introduction of new slivers F) is made possible or facilitated.

Gemäß Fig. 7 ist erkennbar, wie der Querschnitt des Faserverbandes F in Arbeitsrichtung A abnimmt und der Faserverband F dabei verdichtet wird. Die austretende Luft entweicht sowohl durch die seitlichen Öffnungen zwischen zwei parallelen Wandelementen 47a bis 50b als auch durch die Zwischenräume e, f und g zwischen hintereinander angeordneten Leitelementen, Die Verdichtung des Fasermaterials erfolgt zwischen zwei Wandelementen 47a, 47b, 48a, 48b, 49a, 49b und 50a, 50b jeweils nur in einer Richtung, z. B. in senkrechter oder waagerechter Richtung. Dadurch, daß das Fasermaterial bei einem Leitelement 47 bis 50 jeweils nur an den beiden Flächen der einander gegenüberliegenden Wandelemente 47a bis 50b entlanggleitet, zur Seite hin aber jeweils wegen der Öffnung keine Gleitfläche vorhanden ist, ist die Reibung reduziert. Dadurch, daß die benachbarten Leitelemente 47 bis 50 jeweils um 90° zueinander gedreht sind, kann der Faserverband - wenn bei einem Leitelement Öffnungen zu den Seiten hin vorhanden sind - trotzdem durch die Wandelemente des davor und dahinter angeordneten Leitelementes dennoch nicht ausweichen und ist dadurch geführt. Diese Ausbildung ist für starke Verdichtung mit hohem Luftaustritt geeignet. 7 it can be seen how the cross section of the fiber structure F in Working direction A decreases and the fiber structure F is compressed. The escaping air escapes through the side openings between two parallel wall elements 47a to 50b as well as through the spaces e, f and g between guiding elements arranged one behind the other, the compression of the Fiber material takes place between two wall elements 47a, 47b, 48a, 48b, 49a, 49b and 50a, 50b only in one direction, e.g. B. in vertical or horizontal Direction. The fact that the fiber material in a guide element 47 to 50 each only on the two surfaces of the opposing wall elements 47a to 50b slides along, but no sliding surface to the side due to the opening the friction is reduced. Because the neighboring guide elements 47 to 50 are rotated 90 ° to each other, the fiber structure - if at A guide element has openings to the sides - nevertheless through the However, wall elements of the guide element arranged in front and behind are not evade and is guided. This training is for strong compaction with suitable for high air outlet.

Entsprechend Fig. 8 sind zwischen den Leitelementen 47 bis 50 in Arbeitsrichtung keine Abstände vorhanden. Diese Ausführungsform kann bei einer Verdichtung mit geringerem Luftaustritt verwendet werden.8 there are none between the guide elements 47 to 50 in the working direction Clearances exist. This embodiment can with a compression less air outlet can be used.

Nach Fig. 9 sind abwechselnd hintereinander zwei Wandelemente 51, 51b (nur 51a dargestellt), 52a, 52b (nur 52a dargestellt) und zwei Fasermaterialtrichter 53 und 54 angeordnet.9, two wall elements 51, 51b (only 51a 52a, 52b (only 52a shown) and two fiber material hoppers 53 and 54 arranged.
