Description

Die Erfindung betrifft ein Spinnverfahren mit Vorspinnmaschinen und mit Ringspinnmaschinen, das sowohl mit kurzen Fasern wie Baumwolle und synthetischen Fasern mit Stapellängen wie Baumwolle als auch mit Wolle und synthetischen Fasern mit Stapellängen wie Wolle und deren Mischungen einsetzbar ist.The invention relates to a spinning process with roving machines and with ring spinning machines, both with short fibers like Cotton and synthetic fibers with staple lengths like cotton as well as wool and synthetic fibers with staple lengths how wool and its blends can be used.

Im üblichen Spinnverfahren der Baumwollspinnerei und der Kammgarnspinnerei mit Vorspinnmaschinen (Flyern) werden Vorgarnspulen mit einem Gewicht von bis zu 3 kg verwendet, die eine Anfangs-Wicklungshöhe von etwa 360 mm bis etwa 410 mm (14 englische Zoll bis 16 englische Zoll) und einem größten Wicklungsdurchmesser von etwa 140 mm bis 180 mm (5 1/2 englische Zoll bis 7 englische Zoll) aufweisen. Diese Spulenabmessungen werden allgemein als optimal vor allem bezüglich der erreichbaren Produktionsgeschwindigkeit der Vorspinnmaschine, der Handhabung der Vorgarnspulen hinsichtlich ihres Gewichts und ihrer Form, der Gestaltung des Gatters der Ringspinnmaschine und weiterer Einflußfaktoren angesehen und sind seit langer Zeit unverändert.In the usual spinning process of cotton spinning and worsted spinning with roving machines (flyers) roving bobbins Weighing up to 3 kg used, which has an initial winding height from about 360 mm to about 410 mm (14 English Inches to 16 inches) and a largest winding diameter from about 140 mm to 180 mm (5 1/2 English inches to 7 English inches). These coil dimensions become general as optimal especially with regard to the achievable production speed the roving machine, the handling of the Roving bobbins in terms of their weight and shape, the Design of the gate of the ring spinning machine and other influencing factors viewed and have remained unchanged for a long time.

Bei den Maschinen und Einrichtungen, die für die genannten Spinnverfahren eingesetzt werden, haben sich in den letzten Jahren viele und wesentliche Neuerungen und Weiterentwicklungen ergeben, von denen hier vor allem die folgenden genannt und erläutert werden sollen. Die Erläuterung ist kurz gehalten, da die Neuerungen dem Fachmann bekannt und in den zitierten Druckschriften ausführlich beschrieben und dargestellt sind. In the machines and equipment for the above Spinning processes have been used in recent years Years of many and significant innovations and further developments result, of which the following are mentioned and explained should be. The explanation is short because the Innovations known to the expert and in the cited publications are described and illustrated in detail.

Die Vorspinnmaschinen werden mit Mehrachsantrieben ausgestattet. Ein derartiger, als Vierachsenantrieb ausgebildeter Mehrachsantrieb ist in der DE 34 17 779 C2 dargestellt und beschrieben. Die Flügel, die Spulen, die Spulenbank und auch das Streckwerk der Vorspinnmaschine werden jeweils durch eigene, häufig mehrere, gesondert drehzahlsteuerbare Motoren angetrieben. Hierdurch entfällt das bisher übliche stufenlos verstellbare, in der Regel als Konustrieb ausgebildete Getriebe zum Antrieb der Spulen und der Spulenbank. Diese Neuerung des Mehrachsenantriebs bietet neben dem einfacheren Aufbau der Vorspinnmaschine den Vorteil der genaueren Steuerbarkeit der Arbeitsorgane, also insbesondere der Drehzahldifferenz zwischen den Flügeln und den Spulen und der Hubgeschwindigkeit der Spulenbank. Hierdurch wird eine genauere Steuerung des Aufbaus der Wicklung der Vorgarnspulen möglich, wodurch wiederum Fehlverzüge und ein Abrutschen von Windungen vermieden werden.The roving machines are equipped with multi-axis drives. Such a multi-axis drive designed as a four-axis drive is shown and described in DE 34 17 779 C2. The wings, the spools, the spool bank and also the drafting system of the roving machine are each made by their own, often several, separately driven speed controllable motors. hereby the previously customary, continuously adjustable, in the Usually designed as a cone gear for driving the Coils and the coil bank. This innovation of the multi-axis drive offers in addition to the simpler structure of the roving machine Advantage of more precise controllability of the work organs, in particular the speed difference between the wings and the Spools and the lifting speed of the spool bank. This will more precise control of the construction of the winding of the roving bobbins possible, which in turn causes delays and slipping of turns can be avoided.

Die Vorspinnmaschinen werden allgemein mit selbsttätigen Spulenwechselvorrichtungen ausgerüstet, durch die die Vorgarnspulen selbsttätig aus der Spulenbank entnommen und in Hängewagenzüge eingestellt werden, die in der Regel überkopf in der Spinnerei verfahrbar sind. Hierdurch werden die Bedienpersonen von der schweren Arbeit des Entnehmens der Vorgarnspulen aus der Vorspinnmaschine und ihr Abhängen in eine Transportvorrichtung entlastet. Eine derartige Spulenwechselvorrichtung ist in der DE 36 30 214 C3 dargestellt und beschrieben.The roving machines are generally equipped with automatic bobbin changing devices equipped through which the roving bobbins automatically removed from the spool bank and in hanging trolley trains which are usually set overhead in the spinning mill are movable. As a result, the operators of the heavy work of removing the roving bobbins from the roving machine and relieved of their hanging in a transport device. Such a bobbin changing device is in DE 36 30 214 C3 shown and described.

Die Hängebahnsysteme sind häufig so ausgebildet, daß die Hängewagenzüge in die Gatter der Ringspinnmaschinen einfahren können und die Vorgarnspulen von den in den Hängewagenzügen verbleibenden Vorgarnspulen abgearbeitet werden. Eine derartige Anlage ist bspw. in der DE 37 09 540 C2 dargestellt und beschrieben. In anderen Fällen sind selbsttätige Spulenaustauschvorrichtungen im Einsatz, durch die die Vorgarnspulen aus den Hängewagenzügen in die Hängehalter der Gatter der Ringspinnmaschine umgesetzt werden. Eine derartige Vorrichtung ist bspw. in der DE 37 34 275 A1 dargestellt und beschrieben. In beiden Fällen sind auch hierdurch die Bedienpersonen von der "Muskelarbeit" des Handhabens der Vorgarnspulen in Überkopfhöhe entlastet.The monorail systems are often designed so that the monorail trains can enter the gates of the ring spinning machines and the roving bobbins from those remaining in the hanging car trains Roving bobbins are processed. Such a facility is For example, shown and described in DE 37 09 540 C2. In other cases are automatic coil exchange devices in the Use, through which the roving bobbins from the hanging trolley trains in the hangers of the gates of the ring spinning machine are implemented. Such a device is, for example, in DE 37 34 275 A1 shown and described. In both cases, too the operators of the "muscle work" of handling relieves the roving bobbins at overhead.

Obwohl diese Neuerungen bereits seit vielen Jahren bekannt sind, wurde bisher nicht erkannt, daß durch ihre erfindungsgemäße Kombination die Möglichkeit gegeben ist, die Abmessungen der Vorgarnspulen und damit deren Gewicht wesentlich über die bisher üblichen Maße anzuheben, ohne daß die Güte der Bewicklung der Vorgarnspulen und damit die Qualität des Erzeugnisses beeinträchtigt und ohne daß die körperliche Beanspruchung der Bedienpersonen erhöht wird. Keines der zitierten Dokumente gibt auch keinen Hinweis darauf, daß die in ihm offenbarten Merkmale die Möglichkeit bieten, das Gewicht der Vorgarnspulen wesentlich zu erhöhen.Although these innovations have been known for many years, was not previously recognized that by their combination according to the invention the possibility is given of the dimensions of the roving bobbins and thus their weight significantly above that previously usual dimensions without increasing the quality of the winding of the Roving bobbins and thus the quality of the product and without the physical strain on the operators is increased. None of the documents cited are there no indication that the features disclosed in it the Offer possibility to significantly increase the weight of the roving bobbins increase.

Es wurde dadurch auf die Vorteile verzichtet, die Produktion der Vorspinnmaschine insbesondere bei gröberen Vorgarnen durch längere Laufzeit der Vorgarnspulen mit weniger Stillständen zum Zwecke des Spulenwechsels zu erhöhen, die Transportkapazität des Hängebahnsystems zu steigern und an den Ringspinnmaschinen größere Lauflängen mit weniger häufigem Wechsel der Vorgarnspulen zu erreichen und damit verbundene Qualitätseinbußen durch Ansetzer-Dickstellen zu vermeiden.The advantages of producing the Roughing machine, especially for coarser rovings due to longer ones Running time of the roving bobbins with less downtime Purpose of spool change to increase the transport capacity of the To increase the monorail system and larger on the ring spinning machines Run lengths with less frequent change of roving bobbins to achieve and associated quality losses due to thicker piecing to avoid.

Es wurde zwar bereits Vorgarnspulen mit einem Gewicht von 5 kg und einer größten Wicklungshöhe von 480 mm und einem größten Wicklungsdurchmesser von 220 mm vorgeschlagen (Melliand 1961, Seite 1229/1230 und 8/1987, seiten 536-541). Dieser Vorschlag war jedoch damals mangels der oben genannten, heute verfügbaren Maschinen und Einrichtungen weder bedienungsmäßig noch spinntechnisch ausführbar. Der Artikel weist selbst auf die Problematik des Handhabens der schweren Vorgarnspulen hin. Ein befriedigender Wicklungsaufbau mit der hohen Zahl von Windungsschichten von Vorgarnspulen mit einem solchen Wicklungsdurchmessers war mit den damals üblichen Konustrieben nicht erzielbar. Aber auch nach Bekanntwerden der oben geschilderten Neuerungen und Weiterentwicklungen war dieser frühe Hinweis nicht sogleich Anstoß dafür, das angestrebte Spulenformat nunmehr zu verwirklichen.There have already been roving bobbins with a weight of 5 kg and a maximum winding height of 480 mm and a largest Winding diameter of 220 mm proposed (Melliand 1961, Pages 1229/1230 and 8/1987, pages 536-541). At the time, however, this proposal was lacking Above mentioned machines and facilities available today not operable in terms of operation or spinning technology. The item points out the problem of handling the heavy Roving bobbins. A satisfactory winding construction with the high number of winding layers of roving bobbins with a such winding diameter was with the cone drives usual at that time not achievable. But also after the The innovations and further developments described above was this early notice not immediately impetus for the desired spool format now to be realized.

Die Erfindung hat das durch das Fortschreiten der Entwicklung entstandene Potential zur Steigerung der Abmessungen und des Gewichts von Vorgarnspulen und die dadurch erzielbaren Vorteile erkannt und durch erfinderische Auswahl und Kombination der hierfür ausschlaggebenden Maßnahmen das gesteckte Ziel erreicht.The invention has this through the advancement of development created potential to increase the dimensions and weight of roving bobbins and the advantages they can achieve recognized and by inventive selection and combination of decisive measures for achieving this goal.

Wie aus Fig. 1 erkennbar, weist eine Spinnanlage, an der die Erfindung beispielshalber erläutert wird, zwei Vorspinnmaschinen 1 und vier Ringspinnmaschinen 2 bzw. 2' auf. Es versteht sich jedoch, daß eine Spinnanlage auch eine andere Anzahl von Vorspinnmaschinen 1 und Ringspinnmaschinen 2, 2' aufweisen kann. Zwischen den Vorspinnmaschinen 1 und den Ringspinnmaschinen 2, 2' erstreckt sich ein Hängebahnsystem 3 bekannter Art, in dem nicht dargestellte Hängewagenzüge von Hand oder selbsttätig bspw. mittels geläufiger ortsfester, auf die Hängewagenzüge wirkender Reibradantriebe verfahrbar sind. Die Hängewagenzüge sind mit Hängehaltern versehen, in die Vorgarnspulen einhängbar sind.As can be seen from Fig. 1, a spinning system on which the invention Two pre-spinning machines 1 will be explained by way of example and four ring spinning machines 2 and 2 '. However, it is understood that a spinning machine also a different number of roving machines 1 and ring spinning machines 2, 2 '. Between the roving machines 1 and the ring spinning machines 2, 2 'extends a monorail system 3 of known type, in which Hanging carriage trains, not shown, by hand or automatically For example, by means of common, stationary, acting on the hanging car trains Friction wheel drives are movable. The hanging wagon trains are provided with hanging brackets into which roving bobbins can be hung.

Die Vorspinnmaschinen 1 weisen je einen Motor 4 zum Antrieb ihres Streckwerks, einen Motor 5 zum Heben und Senken ihrer Spulenbank, mindestens zwei Motoren 6 zum Antrieb ihrer Flügel und mindestens zwei Motoren 7 zum Antrieb ihrer Spulen auf. Mindestens die Motoren 5, 6 und 7 zum Antrieb der Spulenbank, der Flügel und der Spulen sind mittels einer rechnergeführten, selbsttätigen Steuervorrichtung 8 in der für den Aufbau der Spulenwicklung erforderlichen Weise feinfühlig drehzahlsteuerbar. Dadurch ist das Herstellen der Wicklung der Vorgarnspulen 11 sehr exakt steuerbar und bewirkt auch bei den vielen Vorgarnschichten einer erfindungsgemäßen Vorgarnspule 11 einen sauberen und stabilen Aufbau der Wicklung.The roving machines 1 each have a motor 4 for driving their drafting system, a motor 5 for lifting and lowering their bobbin, at least two motors 6 for driving their wings and at least two motors 7 to drive their coils. At least the motors 5, 6 and 7 for driving the coil bank, the The wing and the coils are automatic control device 8 in the for the construction of the coil winding required speed-sensitive control. As a result, the winding of the roving bobbins 11 is produced very precisely controllable and also works with the many roving layers a roving bobbin 11 a clean one and stable construction of the winding.

Gemäß Fig. 1 ist den beiden Vorspinnmaschinen 1 eine selbsttätige Spulenwechselvorrichtung 9 zugeordnet, die volle Spulen aus der Spulenbank entnehmen und in die Hängehalter eines in der Hängebahn 3 der betreffenden Vorspinnmaschine 1 zugestellten Hängewagenzugs einstellen kann. Dabei kann die Spulenwechselvorrichtung 9 selbstverständlich im Austausch auch leere Hülsen aus dem Hängewagenzug in die Spulenbank einwechseln. Die Spulenwechselvorrichtung 9 ist vor den Vorspinnmaschinen 1 verfahrbar, so daß sie beide Vorspinnmaschinen 1 bedienen kann. Durch diese Spulenwechselvorrichtung 9 ist die Bedienung der Vorspinnmaschinen 1 vom Handhaben der erfindungsgemäßen schweren Vorgarnspulen 11 entlastet.1, the two roving machines 1 is an automatic Coil changing device 9 assigned to the full bobbins remove from the coil bank and into the hanger one in the Monorail 3 of the relevant roving machine 1 delivered Can adjust the trolley. The bobbin changing device 9 of course in exchange also empty tubes change the hanging trolley train into the spool bank. The bobbin changer 9 can be moved in front of the roving machines 1, so that they can operate both roving machines 1. Through this Bobbin changing device 9 is the operation of the roving machines 1 of handling the heavy roving bobbins according to the invention 11 relieved.

In der Ausführungsform der Fig. 3 ist die selbsttätige Spulenwechselvorrichtung 9 gemäß der EP 0 585 827 B1 ausgebildet. Die Darstellung dieser Spulenwechselvorrichtung 9 ist hier sehr weitgehend schematisiert und vereinfacht, für ihre ins Einzelne gehende Darstellung sei daher auf die genannte Patentschrift verwiesen. Es versteht sich, daß die Vorspinnmaschinen 1 auch in dieser Ausführungsform über die in Fig. 1 dargestellten Arbeitsorgane Streckwerksmotor 4, Spulenbankmotor 5, Flügelmotoren 6, Spulenmotoren 7 und Steuervorrichtung 8 verfügen. Der Übersichtlichkeit halber ist auf die Darstellung dieser Arbeitsorgane hier verzichtet.In the embodiment of Fig. 3 is the automatic bobbin changing device 9 according to EP 0 585 827 B1. The Representation of this bobbin changing device 9 is very here largely schematic and simplified, for their in detail The description is therefore based on the patent mentioned directed. It is understood that the roving machines 1 also in this embodiment via the working elements shown in Fig. 1 Drafting motor 4, reel bench motor 5, vane motors 6, Coil motors 7 and control device 8 have. The clarity is half on the representation of these organs waived here.

Durch die jeweils zwei Reihen von Flügeln und Spulen der Vorspinnmaschinen 1 verlaufen gesonderte, den jeweiligen Vorspinnmaschinen zugeordnete Hängebahnen 14, die jeweils durch Rücklaufbahnen 15 zu einem geschlossenen Hängebahnsystem verlegt sind. In diesem Hängebahnsystem 14, 15 sind mit Hängehaltern für Vorgarnspulen und Vorgarnhülsen ausgerüstete Hängewagenzüge verfahrbar. Es versteht sich, daß die hinter den Vorspinnmaschinen 1 liegenden Rücklaufbahnen 15 dieses Hängebahnsystem zweigleisig ausgeführt sein können, um die Hängewagenzüge beider Trume 3',3" aus dem Flügelbereich aufnehmen zu können. Die Kannenfelder 16 der Vorspinnmaschinen sind zu diesem Zweck etwas von den Vorspinnmaschinen abgerückt.Through the two rows of wings and spools of the roving machines 1 run separate, the respective roving machines assigned suspension tracks 14, each by return tracks 15 laid to a closed monorail system are. In this monorail system 14, 15 are with hanging brackets for Roving bobbins and roving sleeves equipped with hanging trolley trains can be moved. It is understood that the behind the roving machines 1 lying return paths 15 this monorail system double track can be carried out to the trolley trains of both dreams 3 ', 3 " to be able to record from the wing area. The pitcher fields 16 The roving machines are somewhat of the roving machines for this purpose moved away.

Zum Spulenwechsel fahren mit Vorgarnhülsen bestückte Hängewagenzüge aus der Rücklaufbahn 15 in die Hängebahnen 14 ein. Durch zweimaliges Anheben und Absenken der Spulenbank werden die Vorgarnspulen aus der Spulenbank in die Hängewagenzüge und Vorgarnhülsen aus den Hängewagenzügen in die Spulenbank umgehängt. Dann fahren die Hängewagenzüge wieder in die Rücklaufbahn 15 aus.Hanging trolley trains equipped with roving sleeves are used to change bobbins from the return path 15 into the suspension paths 14. By The roving bobbins are raised and lowered twice from the spool bank into the hanging trolley trains and roving sleeves slipped from the hanging car trains into the spool bank. Then the hanging wagon trains move back into return path 15.

Jeder Vorspinnmaschine 1 ist ein Vorgarnspulen-/Vorgarnhülsen-Umsetzer 17 bzw. 17' zugeordnet, mittels dessen Vorgarnspulen aus den in den Rücklaufbahnen 15 umlaufenden Hängewagen in Hängewagen in den Bahnabschnitte 3' bzw. 3" des die Vorspinnmaschinen 1 mit den Ringspinnmaschinen 2 verbindenden Hängebahnsystems 3 umgehängt werden können. Damit die Umsetzer 17, 17' unabhängig voneinander umsetzen können, ist das Hängebahnsystem 3 hinter den Vorspinnmaschinen 1 in zwei Zweige 3', 3" aufgespalten - der Umsetzer 17 setzt in den Zweig 3' um, der Umsetzer 17' in den Zweig 3". Im Austausch setzen die Umsetzer 17, 17' auch Vorgarnhülsen aus dem Hängebahnsystem 3 in das Hängebahnsystem 14, 15 um.Each roving machine 1 is a roving bobbin / roving tube converter 17 or 17 'assigned by means of its roving bobbins from the hanging trolleys circulating in the return paths 15 in hanging trolleys in the web sections 3 'or 3 "of the roving machines 1 monorail system connecting the ring spinning machines 2 3 can be reassigned. So that the converters 17, 17 ' The monorail system is able to implement independently of each other 3 behind the roving machines 1 split into two branches 3 ', 3 " - The converter 17 converts to the branch 3 ', the converter 17 'into branch 3 ". In exchange, the converters 17, 17' roving sleeves from the monorail system 3 into the monorail system 14, 15 µm.

Die Gatter der Ringspinnmaschinen 2 sind so ausgebildet, daß das Hängebahnsystem 3 durch diese Gatter verlaufen kann, so daß die Hängewagenzüge in die Gatter einfahren können. Die Vorgarnspulen 11 können daher aus den Hängewagenzügen heraus ablaufen und brauchen nicht aus diesen in die Hängehalter im Gatter der Ringspinnmaschinen 2 eingewechselt zu werden. Dadurch ist auch die Bedienung der Ringspinnmaschinen 2 vom Handhaben der erfindungsgemäßen schweren Vorgarnspulen 11 entlastet.The gates of the ring spinning machines 2 are designed so that the Monorail system 3 can run through this gate, so that the Hanging carriage trains can enter the gate. The roving bobbins 11 can therefore run out of the hanging car trains and do not need from these in the hangers in the creel of the ring spinning machines 2 to be substituted. This is also the Operation of the ring spinning machines 2 by handling the invention heavy roving bobbins 11 relieved.

Die Erfindung ist aber auch in Verbindung mit Ringspinnmaschinen 2' ausführbar, die mit selbsttätigen Spulenaustauschvorrichtungen 10 ausgerüstet sind.
