Abstract

To produce slubbing material from a fibre feed, using a card (16) and the like, during the slubbing development the separate slubbings (42, 44, 46, 48) are measured continuously for each running metres. On a deviation of the weight from a nominal value, the cross section of the air passage (50) is varied as a weight correction, leading the air out of the shafts (24, 26, 28, 30) at the flocking stage, at the shaft corresponding to a weight shift in the part-slubbing. Also claimed is an assembly with an air passage (50) in each flocking shaft (24, 26, 28, 30) which is increased or decreased steplessly according to the measured weight of the part-slubbings (42, 44, 46, 48) produced from the flockings (34, 36, 38, 40) in the shafts. Pref. each of the shafts (24, 26, 28, 30) is connected to a monitor (56, 58, 60, 62) located after the card (16), to measure the slubbing weight per running metre. A setting unit (54) for a cover (52) adjusts the working in each shaft according to the monitored readings. The cover (52) has a linear movement, sliding parallel to the sieve forming the air passage. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Luntenherstellung aus Fasergut mit den Merkmalen des Oberbegriffs von Anspruch 1, sowie eine Einrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for making sliver from fiber material with the features of the preamble of claim 1, and a device for performing this method.

Ein derartiges Verfahren findet, obgleich druckschriftlich nicht belegbar, in der Spinnereitechnik Anwendung, um Lunten mit sehr kleinem Laufmetergewicht zu produzieren. Dies wurde durch Unterteilen des Füllschachtes in eine Anzahl Teilschächte und somit durch entsprechendes Aufteilen der in den Füllschacht eingespeisten Flockenvorlage in einzelne Vorlagenstreifen erreicht.Such a method is used in spinning technology, although it cannot be documented in printed form, in order to produce fuses with a very small linear weight. This was achieved by dividing the filling shaft into a number of partial shafts and thus by dividing the flake feed fed into the filling shaft into individual template strips.

Aus den einzelnen Vorlagenstreifen werden in der Verarbeitungsvorrichtung, beispielsweise Karde, Florbahnen hergestellt, die nach Verlassen der Verarbeitungsvorrichtung zu Einzellunten verarbeitet werden.In the processing device, card, for example, card webs are produced from the individual template strips, which are processed into single slits after leaving the processing device.

Bei dieser Verfahrensweise war es bisher nicht möglich, Einzellunten mit im wesentlichen gleichbleibendem, geringem Laufmetergewicht zu fertigen, da sich zur Gewichtskorrektur der einzelnen Lunten ein Eingriff in die Einzugsgeschwindigkeit der Verarbeitungsvorrichtung verbietet. In diesem Falle wurde nämlich die Faserdichte sämtlicher Lunten gleichzeitig entsprechend verändert werden.With this procedure, it was previously not possible to produce individual slits with a substantially constant, low linear meter weight, since an intervention in the retraction speed of the processing device is prohibited for correcting the weight of the individual slivers. In this case, the fiber density of all fuses would be changed accordingly at the same time.

Hier setzt nun die Erfindung ein, indem sie aufzeigt, wie sich bei einer gleichzeitigen Verarbeitung von mehreren, eine Karde oder dergleichen Verarbeitungsvorrichtung verlassenden Florbahnen zu Einzellunten das Laufmetergewicht jeder dieser Einzellunten kontinuierlich relativ genau auf einem gewünschten Sollwert halten lässt.This is where the invention comes in, by showing how, with simultaneous processing of a plurality of card webs or carding devices or the like processing device into individual slits, the linear meter weight of each of these individual slits can be kept relatively accurately at a desired target value continuously.

Hierzu wird erfindungsgemäss vorgeschlagen, während der Luntenbildung kontinuierlich die Luntenmasse je laufendem Meter jeder Einzellunte zu messen und bei Gewichtsabweichungen von einem Sollgewicht zur Gewichtskorrektur den Querschnitt des Luftdurchlasses des die Flockenvorlage für die betreffende Einzellunte liefernden Teilschachtes entsprechend zu verändern.For this purpose, it is proposed according to the invention to continuously measure the sliver mass per running meter of each individual sliver during the formation of sliver and to change the cross section of the air passage of the partial shaft supplying the flake template for the respective sliver in the event of weight deviations from a target weight.

Ergeben sich bei der Überwachung des Laufmetergewichtes von Einzellunten Gewichtsabweichungen nach oben, werden diese im wesentlichen kompensiert, indem der Querschnitt des Luftdurchlasses des die betreffende Flockenvorlage liefernden Teilschachts verringert und dadurch das Einspeisen von Fasergut in diesen in der Zeiteinheit entsprechend verlangsamt wird.If there are upward deviations in weight when monitoring the linear meter weight of individual slits, these are essentially compensated for by reducing the cross-section of the air passage of the partial chute providing the flock supply in question and thereby slowing down the feeding of fiber material in the unit of time accordingly.

Bei Abweichungen des Laufmetergewichtes nach unten wird zur Gewichtskorrektur der Luftdurchlassquerschnitt des betreffenden Teilschachtes entsprechend vergrössert.In the event of deviations in the running meter weight downwards Weight correction of the air passage cross section of the relevant sub-shaft enlarged accordingly.

Zur Durchführung des erfindungsgemässen Verfahrens eignet sich mit besonderem Vorteil eine Einrichtung nach den Ansprüchen 2 und 3.A device according to claims 2 and 3 is particularly advantageously suitable for carrying out the method according to the invention.

Die zur Veränderung eines Luftdurchlassquerschnittes durch die Messvorrichtung ansteuerbare Abdeckvorrichtung kann, ebenso wie der Luftdurchlass selbst, eine beliebige Ausbildung aufweisen. Eine sich durch besondere technische Einfachheit auszeichnende Konstruktion ist hierbei Gegenstand des Anspruches 4.The cover device which can be controlled by the measuring device to change an air passage cross section, like the air passage itself, can have any configuration. A construction characterized by special technical simplicity is the subject of claim 4.

In der Zeichnung ist, stark schematisiert und teilweise im Längsschnitt gezeigt, ein Ausführungsbeispiel der Einrichtung zur Durchführung des erfindungsgemässen Verfahrens dargestellt.In the drawing, highly schematized and partially shown in longitudinal section, an embodiment of the device for performing the inventive method is shown.

Mit 10 ist ein oben geschlossener Füllschacht bezeichnet, dem an seiner Oberseite über eine horizontale Förderleitung 12 aus Baumwolle oder synthetischen Fasern bestehende Faserflocken 14 mittels Förderluft zugeführt werden.With 10 is a closed top chute, the top of which is fed via a horizontal conveyor line 12 made of cotton or synthetic fibers fiber flakes 14 by means of conveying air.

Dem Füllschacht 10 ist eine Verarbeitungsvorrichtung 16, beispielsweise in Art einer Karde, nachgeschaltet. Des weiteren ist dieser beispielsweise in vier durch Trennwände 18, 20, 22 voneinander getrennte Teilschächte 24, 26, 28 und 30 unterteilt, in welchen sich jeweils eine Flockenvorlage aufbaut.A processing device 16, for example in the form of a card, is connected downstream of the filling shaft 10. Furthermore, this is subdivided, for example, into four partial shafts 24, 26, 28 and 30 separated from one another by partitions 18, 20, 22, in each of which a flake template is built up.

Mittels Abzugswalzen 32 werden somit aus den Teilschächten 24-30 insgesamt vier streifenförmige Flockenvorlagen 34, 36, 38 und 40 gleichzeitig ab- und gemeinsam in die Karde 16 eingezogen. Dementsprechend fallen an der Karde 16 auch ausgangsseitig vier streifenförmige Flockenvorlagen an, die anschliessend zu Lunten 42, 44, 46 und 48 verarbeitet werden.With the help of take-off rollers 32, a total of four strip-shaped flake templates 34, 36, 38 and 40 are simultaneously withdrawn from the partial shafts 24-30 and drawn into the card 16 together. Accordingly, the card 16 also fall on the output side four strip-shaped flake patterns, which are then processed into fuses 42, 44, 46 and 48.

Die Förderluft kann aus den Teilschächten 24-30 über einen in deren unterem Bereich vorgesehenen Luftdurchlass 50, der vorzugsweise durch ein ebenes Sieb gebildet ist, wieder abströmen. Dieses Sieb erstreckt sich im wesentlichen über die gesamte Schachtbreite und über einen bestimmten Bereich der Höhe des betreffenden Teilschachtes. Die zugeführten Faserflocken 14 lagern sich dabei im unteren Bereich der Teilschächte 24-30 ab, wobei sich zwangsläufig eine Materialsäule mit annähernd gleichmässiger Faserverteilung aufbaut.The conveying air can flow out of the partial shafts 24-30 again via an air passage 50 provided in their lower region, which is preferably formed by a flat sieve. This sieve extends essentially over the entire width of the shaft and over a certain range of the height of the partial shaft in question. The supplied fiber flakes 14 are deposited in the lower region of the partial shafts 24-30, a material column with an approximately uniform fiber distribution inevitably building up.

Jedem Luftdurchlass bzw. Sieb 50 ist vorzugsweise schachtaussenseitig ein Abdeckorgan 52 zugeordnet, das mittels einer Stellvorrichtung 54 beliebieger Ausbildung stufenlos nach oben bis im wesentlichen zur völligen Freigabe bzw. nach unten bis im wesentlichen zum völligen Verschluss des Siebes 50 verstellbar ist. Einfachheitshalber ist lediglich eine dieser Stellvorrichtungen 54 eingezeichnet.Each air passage or sieve 50 is preferably assigned a cover member 52 on the outside of the shaft, which can be adjusted steplessly upwards to essentially complete release or downwards to essentially complete closure of the sieve 50 by means of an adjusting device 54 of any design. For the sake of simplicity, only one of these adjusting devices 54 is shown.

Zur Ermittlung des Luntenlaufmetergewichtes wird jede Lunte 42-48 durch eine ihr zugeordnete Messvorrichtung 56, 58, 60 und 62 hindurchgeführt, durch die jeweils eine der Stellvorrichtungen 54 für die Schieber 52 ansteuerbar ist.To determine the sliver running meter weight, each sliver 42-48 is passed through an associated measuring device 56, 58, 60 and 62, through which one of the adjusting devices 54 for the slider 52 can be controlled.

Hierzu ist jede Messvorrichtung 56-62 über jeweils eine Steuerleitung 64 mit derjenigen Stellvorrichtung 54 verbunden, die dem Schieber 52 desjenigen Teilschachtes zugeordnet ist, dessen Flockenvorlage zur Bildung der zu messenden Lunte vorgesehen ist. Der Einfachheit halber ist lediglich eine dieser Steuerleitungen 64 eingezeichnet.For this purpose, each measuring device 56-62 is connected via a control line 64 to the actuating device 54, which is assigned to the slide 52 of the sub-shaft whose flake template is provided to form the sliver to be measured. For the sake of simplicity, only one of these control lines 64 is shown.

Durch die über die Messvorrichtungen 56-62 zu ermittelnden Regelgrössen und entsprechende Ansteuerung der Schieber 52 ist somit die zur Einhaltung des besonders geringen Luntenschnurgewichtes je laufendem Meter erforderliche Faserdichte der einzelnen, streifenförmigen Flockenvorlagen 34-40 durch entsprechende Beeinflussung des Abzuges der Förderluft aus den Teilschächten 24-30 beeinflussbar, obgleich sämtliche Flockenvorlagen 34-40 gemeinsam in der Karde 16 zu Faserflor und danach zu Einzellunten 42-48 verarbeitet werden.Due to the control variables to be determined via the measuring devices 56-62 and the corresponding actuation of the slider 52, the fiber density of the individual, strip-shaped flake templates 34-40 required to maintain the particularly low sliver cord weight per running meter is thus influenced by correspondingly influencing the extraction of the conveying air from the partial shafts 24 -30 can be influenced, although all of the flake patterns 34-40 are processed together in card 16 to form fiber pile and then to individual slivers 42-48.
