- the object of the invention is to find a direct means of transport for the wet or dry filaments arising during the spinning process or without thread closure to form thousands of spinning belts in a relatively orderly, parallel position, to the next working stage, which allows this without changing the properties and mutual assignment of these to promote a longer distance gently, in the case of start-up or in the event of malfunctions a new threading must be given safely and quickly because of the usually high working speeds.
- the object is achieved in that the beginning of a filament bandage at certain intervals of the conveyor line is detected by means of conveyors by means of injectors arranged one behind the other, in order then in each case in a flow generated by the injector within a closed channel, past guide organs arranged transversely there to be levitated freely until part of the conveying means is discharged laterally, while the next injector takes over the function of further conveying and that after the application the injectors are switched off, the filament then being supported by the guide elements during the conveying.
- Known hand-applied nozzles are used to transfer the spinning belt, which catch the incoming spinning belt. The free end is cut off.
- the belt running into the feed nozzle is guided past the injector via an auxiliary device and severed between the two, so that the injector sucks it in in the form of a loop which is broken down in the conveying path.
- the feed injector must be a suck in a certain amount of air and thus pull in the tape.
- the ratio between the speed of the intake air at the suction mouth and the speed of the belt (V S / V B ) should be in the range 2 to 25, preferably 15 to 20.
- a device in which two or more units arranged one behind the other are arranged at a small distance from one another as the conveyor line, each consisting of an injector with a subsequent closed channel, including built-in guide elements.
- standardized units one after the other, each consisting of only a few elements - namely an injector, a tube and individual guide elements.
- the length of the channels depends on the performance of the delivery injector, the pressure loss of the delivery air flow due to friction, the required suction air speed and the necessary delivery air speed (suction air and driving air).
- the free exit surface between two units due to the distance between the units should be 2 to 6 times the pipe cross-sectional area.
- the filament array can be deflected by a rotating wheel, the circumferential contour of which is adapted to that of the guide element, and forms part of one of the bends required for the pneumatic deflection, with either wheel or half-pipe elbow being foldable for checking purposes. Due to the rotating wheel under load, wear on the deflection is largely avoided during the mechanical removal of the filament ent matter.

Description
Die Erfindung betrifft ein Verfahren zur Förderung von Filamentverbänden, insbesondere Spinnbänder, über weite Förderstrecken zwecks direkter Kopplung verschiedener Arbeitsstufen einer Faserherstellung und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for conveying filament bandages, in particular spinning belts, over long conveying distances for the purpose of direct coupling of different working stages of a fiber production and a device for carrying out the method.
Bisher ist es üblich, Filamente bzw. Spinnbänder nach dem Spinnprozeß in Kannen zu sammeln, die dann zur nächsten, im allgemeinen räumlich entfernten Anlage transportiert werden, wo das Filament zur weiteren Behandlung - wie Waschen, Verstreckung, Kräuseln usw. - wiederum aus der Kanne abgezogen wird.So far, it has been customary to collect filaments or spinning belts after the spinning process in cans, which are then transported to the next, generally spatially distant facility, where the filament for the further treatment - such as washing, drawing, crimping, etc. - again from the can is subtracted.
Der Nachteil einer solchen Handhabung besteht im wesentlichen darin, daß die empfindlichen Vorprodukte beim Ein-und Auspacken aus der Kanne beschädigt werden können, die örtliche Zuordnung der Filamente untereinander gestört wird, ein erhöhter Transportaufwand durch die kontinuierliche Förderung erforderlich ist und zusätzliche Lagerhaltungskosten entstehen.The main disadvantage of such a handling is that the sensitive preliminary products can be damaged during packing and unpacking from the jug, the local assignment of the filaments to one another is disturbed, an increased transport effort is required due to the continuous conveying and additional storage costs arise.
Aufgabe der Erfindung ist es, eine unmittelbare Transportmöglichkeit für die beim Spinnprozeß anfallenden feuchten oder trockenen Filamente bzw. ohne Fadenschluß zu Tausenden zusammengefaßtenSpinnbänder in relativ geordneter, paralleler Lage, zur nächsten Arbeitsstufe zu finden, die erlaubt, ohne Veränderung der Eigenschaften und gegenseitigen Zuordnung diese über eine längere Strecke schonend zu fördern, wobei im Falle des Anfahrens bzw. bei Störungen ein Neueinfädeln sicher und schnell wegen der meist vorhandenen hohen Arbeitsgeschwindigkeiten gegeben sein muß.The object of the invention is to find a direct means of transport for the wet or dry filaments arising during the spinning process or without thread closure to form thousands of spinning belts in a relatively orderly, parallel position, to the next working stage, which allows this without changing the properties and mutual assignment of these to promote a longer distance gently, in the case of start-up or in the event of malfunctions a new threading must be given safely and quickly because of the usually high working speeds.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß zum Anlegen der Anfang eines Filamentverbandes in bestimmten Abständen der Förderstrecke staffettenartig durch Fördermittel mittels hintereinander angeordneten Injektoren erfaßt wird, um dann jeweils in einer mit dem Injektor erzeugten Strömung innerhalb eines geschlossenen Kanales, vorbei an dort quer angeordneten Führungsorganen, frei schwebend gefördert zu werden, bis ein Teil des Fördermittels seitlich abgeführt wird, während gleichzeitig der nächste Injektor die Funktion zur Weiterförderung übernimmt und daß nach dem Anlegen die Injektoren abgeschaltet werden, wobei dann das Filament über die Führungsorgane während der Förderung gestützt wird.The object is achieved in that the beginning of a filament bandage at certain intervals of the conveyor line is detected by means of conveyors by means of injectors arranged one behind the other, in order then in each case in a flow generated by the injector within a closed channel, past guide organs arranged transversely there to be levitated freely until part of the conveying means is discharged laterally, while the next injector takes over the function of further conveying and that after the application the injectors are switched off, the filament then being supported by the guide elements during the conveying.
Durch wiederholtes Zentrieren in bestimmten Abständen während der schwebenden Förderung beim Anlegen der Filamentanfänge wird auch über weite Förderstrecken ein Verfangen oder Verhaken an den Führungsorganen vermieden, die wiederum erforderlich sind, um beim Normalbetrieb durch mechanischen Abzug einen Verschleiß durch geringe Anlage und eine Verstreckung durch geringe Reibung bei diesem sehr empfindlichen Vorprodukt zu vermeiden. Mit dem Verfahren ist eine sichere und schnelle Einfädelung auch bei kleinem Rohrquerschnitt, der aus Platzgründen oft erforderlich ist, mit geringen Luftmengen möglich, da jeder Injektor etwa im optimalen Betriebspunkt wegen des geringen Druckabfalls auf der Länge gefahren werden kann, so daß eine Verstopfung nicht auftritt. Das Verhältnis zwischen Förderluftgeschwindigkeit und Bandgeschwindigkeit (VT+S/VB) sollte im Bereich von 4 bis 16, vorzugsweise 8 bis 10 liegen.Repeated centering at certain intervals during the pending conveying when the filament starts is also avoided over long conveying distances and prevents the guide elements from getting caught or getting caught, which in turn are necessary in order to prevent wear and tear due to mechanical extraction during normal operation and stretching due to low friction to avoid with this very sensitive intermediate product. With the method, a safe and quick threading is possible even with a small pipe cross-section, which is often required for reasons of space, with small amounts of air, since each injector can be moved along the length at the optimum operating point because of the low pressure drop, so that there is no blockage . The ratio between conveying air speed and belt speed (V T + S / V B ) should be in the range from 4 to 16, preferably 8 to 10.
Für die Übergabe des Spinnbandes werden bekannte Hand-Anlegedüsen vewendet, die das ankommende Spinnband einfangen. Das freie Ende wird abgeschnitten. Das in die Anlegedüse laufende Band wird über Hilfsvorrichtung am Injektor vorbeigeführt und zwischen beiden durchtrennt, so daß der Injektor es in Form einer Schlinge einsaugt, die in der Förderstrecke abgebaut wird. Um die sichere Übergabe des Bandes von der Anlegedüse an einen Förderinjektor zu gewährleisten, muß der Förderinjeklor eine bestimmte Luftmenge ansaugen und so das Band mit einziehen. Das Verhältnis zwischen der Geschwindigkeit der angesaugten Luft am Saugmund und der Geschwindigkeit des Bandes (VS/VB) sollte im Bereich 2 bis 25, vorzugsweise 15 bis 20, liegen.Known hand-applied nozzles are used to transfer the spinning belt, which catch the incoming spinning belt. The free end is cut off. The belt running into the feed nozzle is guided past the injector via an auxiliary device and severed between the two, so that the injector sucks it in in the form of a loop which is broken down in the conveying path. To ensure the safe transfer of the belt from the feed nozzle to a feed injector, the feed injector must be a suck in a certain amount of air and thus pull in the tape. The ratio between the speed of the intake air at the suction mouth and the speed of the belt (V S / V B ) should be in the range 2 to 25, preferably 15 to 20.
Zur Durchführung des Verfahrens dient eine Vorrichtung, bei der als Förderstrecke zwei oder mehrere hintereinander liegende Baueinheiten mit kleinem Abstand untereinander angeordnet sind, die aus jeweils einem Injektor mit anschließendem geschlossenen Kanal, einschließlich eingebauter Führungsorgane, bestehen.To carry out the method, a device is used in which two or more units arranged one behind the other are arranged at a small distance from one another as the conveyor line, each consisting of an injector with a subsequent closed channel, including built-in guide elements.
Bei Förderung über große Entfernungen ist es vorteilhaft standardisierte Baueinheiten hintereinander anzuordnen, die jeweils nur aus wenigen Elementen - nämlich einem Injektor, einem Rohr und einzelnen Führungsorganen - bestehen. Die Länge der Kanäle hängt von der Leistung des Förderinjektors, dem Druckverlust des Förderluftstromes durch Reibung, der erforderlichen Saugluftgeschwindigkeit und der notwendigen Förderluftgeschwindigkeit (Saugluft und Treibluft) ab. Die durch den Abstand der Baueinheiten untereinander vorhandene freie Austrittsfläche zwischen zwei Baueinheiten sollte das 2- bis 6fache der Rohrquerschnittsfläche betragen.When conveying over long distances, it is advantageous to arrange standardized units one after the other, each consisting of only a few elements - namely an injector, a tube and individual guide elements. The length of the channels depends on the performance of the delivery injector, the pressure loss of the delivery air flow due to friction, the required suction air speed and the necessary delivery air speed (suction air and driving air). The free exit surface between two units due to the distance between the units should be 2 to 6 times the pipe cross-sectional area.
Durch flache Querschnitte, die rechteckige oder ovale Form besitzen können, ist es möglich, auch Spinnbänder bis zu einer Breite von 300 bis 400 mm in einem Kanal so zu führen, daß für alle parallel laufenden Filamente etwa gleiche Förderbedingungen herrschen und daß der Verbrauch an Fördermittel Luft gering ist.Due to flat cross sections, which can have a rectangular or oval shape, it is also possible to guide spinning belts up to a width of 300 to 400 mm in a channel in such a way that all the filaments running in parallel have approximately the same conveying conditions and that the consumption of conveying means Air is low.
Vorteilhaft haben sich Führungsorgane erwiesen, die von der Rohrwandung her in das Rohr hineinragen und deren Anblasfläche unter einen Winkel von 10° bis 60° zur Rohrachse in Förderrichtung geneigt ist und die oben einen schmalen Sattel besitzen, der zu den Wänden des Kanals leicht ansteigt, wodurch sich während des Laufes das Spinnband immer automatisch zentriert.Guide elements which have protruded from the pipe wall into the pipe and whose blowing surface is inclined at an angle of 10 ° to 60 ° to the pipe axis in the conveying direction and which have a narrow saddle at the top, which rises slightly towards the walls of the channel, have proven advantageous. which means that the spinning belt always centers itself automatically during the run.
Schließlich können Umlenkungen des Filamentverbandes durch ein mitdrehendes Rad erfolgen, welches in seiner Umfangskontur der des FÜhrungsorgans angepaßt ist, und einen Teil eines des für die pneumatische Umlenkung notwendigen Krümmers bildet, wobei zur Kontrolle entweder Rad oder Halbrohrbogen abklappbar sind. Durch das unter Belastung mitdrehende Rad wird während des mechanischen Abzuges des Filamtentverbandes ein Verschleiß an der Umlenkung weitgehend vermieden.Finally, the filament array can be deflected by a rotating wheel, the circumferential contour of which is adapted to that of the guide element, and forms part of one of the bends required for the pneumatic deflection, with either wheel or half-pipe elbow being foldable for checking purposes. Due to the rotating wheel under load, wear on the deflection is largely avoided during the mechanical removal of the filament entverband.

In Fig. 1 ist die Einfädelung eines Filamentverbandes 2 über eine weite Förderstecke 1 dargestellt.In Fig. 1, the threading of a filament dressing 2 is shown over a wide conveyor path 1.
Aus der Spinnmaschine 2 werden kleine Filamentverbände 3 in Form eine Spinnbandes 4 über ein Abzugswerk 5 abgezogen. Zum Einfädeln wird der Anfang des Spinnbandes im Bereich 6 mit einer Anlegedüse 7 in den ersten Injektor 8 eingeführt, dem Luft 9 über Leitung 10 zugeführt wird. Die Umlenkung erfolgt im Rohrkrümmer 11, der aus einem abklappbaren Bogenteil 12 und einer Rolle 13 gebildet wird. Am Ende des Rohres ist durch einen Abstand zum nächsten Injektor ein ringförmiger Schlitz 14 zum Ablassen der Treibluft 9 vorhanden. Die folgenden Baueinheiten 15 bestehen aus einem Injektor 8 mit Rohr 16 und evtl. einem Führungsorgan 17. Am Ende sitzt ein sogenannter Verlustinjektor 18, der den Spinnbandanfang ansaugt, von wo er mit einer Anlegedüse 7 auf das Lieferwerk 19 für die Nachbehandlungsanlage 20 gelegt wird. Danach wird die Luftzufuhr abgeschaltet und das Spinnband 4 mechanisch gefördert.
In Fig. 2 + 3 wird ein Längs- und ein Querschnitt durch das Rohr 16 an der Stelle gezeigt, wo ein Führungsorgan 17 für ein Spinnband 3 eingebaut ist, welches aus einem in Förderrichtung geneigten Körper 21 besteht, der eine zu den Rohrwandungen 22 ansteigende sattelförmige Auflage 23 besitzt, über die das Spinnband 4 während der mechanischen Förderung geführt wird.2 + 3, a longitudinal and a cross section through the
In Fig. 4 wird eine Umlenkung des Spinnbandes 4 gezeigt. Auf einem Flansch 24 ist an einem Gelenk 25 ein klappbarer Bogenteil 12 befestigt, der unter Verbleiben eines geringen Spaltes an die Rolle 13 anschließt, und mit diesem einen Rohrkrümmer 11 bildet, indem das Spinnband 4 mit dem Luftstrom eingelenkt wird. Bei der späteren mechanischen Förderung liegt das Spinnband 4 an der Rolle 13 an, welche mitdreht.A deflection of the
In einer Anlage wird ein Spinnband mit einem Bandgewicht von bis zu 40 g/m und ca. 70 % Feuchte, einer Bandbreite von bis zu 30 mm über eine Entfernung von bis zu 30 m transportiert werden. Als Kanal wird hier ein Glasrohr DN 80 eingesetzt. Die vorgeschaltete Ringspaltinjektoren haben einen lichten Saugmunddurchmesser von 50 mm. Zur Unterstützung des Spinnbandes im Rohr wurden die 4 m langen Förderrohre aus zwei Rohrstücken zusammengesetzt und an der Flanschstelle ein Führungsblech eingesetzt. Eingebaute Umlenkrollen sorgen für eine zweimalige Umlenkung des Bandes in der vertikalen und in der horizontalen Ebene.A spinning belt with a belt weight of up to 40 g / m and approx. 70% moisture and a belt width of up to 30 mm will be transported in a system over a distance of up to 30 m. A glass pipe DN 80 is used here as a duct. The upstream annular gap injectors have a clear suction mouth diameter of 50 mm. To support the spinning belt in the tube, the 4 m long conveyor tubes were assembled from two tube sections and a guide plate was inserted at the flange point. Built-in deflection rollers ensure that the belt is deflected twice in the vertical and in the horizontal plane.
In einer zweiten Anlage muß jedoch ein Spinnband von einer Breite bis zu 150 g/m mit ca. 10 % Feuchte über eine Entfernung von ca. 12 m gefördert werden. Hierzu wurde ein Ovalrohr mit ca. 300 mm Breite und ca. 80 mm Höhe verwendet. Die Injektoren sind dieser Form angepaßt und haben statt des Ringspaltes eine Vielzahl von feinen Bohrungen auf dem Umfang des ovalen Ringkanals für die Treibluftzufuhr. Zusätzliche Einbauten waren hier nicht erforderlich, da das Band aufgrund seiner geringen Feuchte einen günstigen Reibbeiwert besitzt.In a second system, however, a spinning belt with a width of up to 150 g / m and approximately 10% moisture must be conveyed over a distance of approximately 12 m. An oval tube with a width of approx. 300 mm and a height of approx. 80 mm was used for this. The injectors are adapted to this shape and instead of the annular gap have a large number of fine bores on the circumference of the oval annular channel for the supply of propellant air. Additional installations were not necessary because the belt has a favorable coefficient of friction due to its low moisture.
