Abstract

The internal transport system at a roving frame (1), for the movement of bobbins and empty bobbin sleeves, has a mechanism (13) to clean empty bobbin sleeves of residual material at the transport system (15).

Description

Die Erfindung betrifft eine Vorspinnmaschine mit einer maschineninternen Transporteinrichtung zum Fördern voller Spulen und leerer Hülsen im Bereich der Vorspinnmaschine.The invention relates to a roving machine with an internal transport device for conveying full bobbins and empty sleeves in the area of the roving machine.

Da auslaufendes Vorgarn in Ringspinnmaschinen Fadenbrüche verursacht, ist man bestrebt, leerlaufende Vorgarnspulen gegen volle Vorgarnspulen auszutauschen, bevor sie völlig leergelaufen sind. Dies führt dazu, daß ausgelaufene, im folgenden als leer bezeichnete, von der Ringspinnmaschine abgenommene Hülsen nicht ganz leer sind, sondern noch mehr oder minder große Reste von Vorgarn enthalten. Diese Reste können aus wenigen Windungen bis zu Schichten von Vorgarn bestehen. Vor Aufstecken der leeren Hülsen auf die Spindeln von Vorspinnmachine müssen diese Vorgarnreste entfernt werden.Since outfeed roving causes thread breaks in ring spinning machines, efforts are made to replace idling roving bobbins with full roving bobbins before they are completely empty. This leads to the fact that sleeves which have leaked out and are referred to below as empty and removed from the ring spinning machine are not completely empty, but instead contain residues of roving which are more or less large. These residues can consist of a few turns up to layers of roving. These roving residues must be removed before the empty tubes are placed on the spindles of the roving machine.

Es sind Vorrichtungen in vielfältiger Form bekannt, mittels derer solche Vorgarnreste von Vorgarnhülsen selbsttätig entfernt werden können. In der IPC-Klasse B65H 73/00 sind derartige Vorrichtungen dokumentiert.Devices in various forms are known by means of which such roving residues can be removed automatically from roving sleeves. Such devices are documented in the IPC class B65H 73/00.

Es ist auch schon bekannt (EP 0 454 897 A1), eine solche Vorrichtung zum Entfernen von Vorgarnresten von Vorgarnhülsen in einem Transportsystem von Vorgarnspulen zwischen Ringspinnmaschinen und Vorspinnmaschinen anzuordnen. Hierbei ist an dem Transportweg der mittels Hängewagen bewegten vollen Spulen und leeren Hülsen eine Umsetzeinrichtung vorgesehen, mittels derer jeweils eine Gruppe leerer Hülsen aus einem Hängewagen entnommen, auf Stiftteller umgesetzt und von diesen zur Reinigungseinrichtung gefördert werden. Von der Reinigungseinrichtung aus werden die von ihren Vorgarnresten befreiten leeren Hülsen auf den Stifttellern zu einer weiteren Umsetzeinrichtung gefördert, mittels derer sie wieder gruppenweise in einen Hängewagen umgesetzt werden.It is also known (EP 0 454 897 A1) to arrange such a device for removing roving residues from roving sleeves in a transport system of roving bobbins between ring spinning machines and roving machines. In this case, a transfer device is provided on the transport path of the full bobbins and empty sleeves moved by hanging trolleys, by means of which a group of empty sleeves is removed from a hanging trolley, transferred to pin plates and from these to the cleaning device be promoted. From the cleaning device, the empty tubes freed of their roving residues are conveyed on the pen plates to a further transfer device, by means of which they are again transferred in groups to a hanging trolley.

Es handelt sich dabei also um eine selbständige Einrichtung, deren Integration in das Transportsystem anlagenindividuell geplant und konstruiert werden muß und deren Steuerung eine Schnittstelle zur Steuerung des Transportsystems aufweist. Da die Hängewagenzüge beim Umsetzen der leeren Hülsen stillstehen müssen, ist ihr Einsatz auf individuell bewegbare Hängewagenzüge beschränkt. Da sie ferner die leeren Hülsen gruppenweise ohne Rücksicht darauf, ob sie Vorgarnreste enthalten, der Reinigungseinrichtung zuführt, verursacht sie u.U. unnötige Mehrarbeit.It is therefore an independent device, the integration of which into the transport system must be planned and constructed individually for the system, and the control of which has an interface for controlling the transport system. Since the hanging trolley trains have to stand still when moving the empty sleeves, their use is restricted to individually moving hanging trolley trains. Furthermore, since it feeds the empty tubes to the cleaning device in groups regardless of whether they contain roving residues, it may cause. unnecessary extra work.

Das Ziel der Erfindung war es, das Reinigen der leeren Hülsen von Vorgarnresten mit geringerem Aufwand an Planungsarbeit, Bauteilen und Steuerungstechnik zu bewerkstelligen. Die Erfindung geht hierbei von einer Vorspinnmaschine aus, die eine maschineninterne Transporteinrichtung zum Fördern voller Spulen und leerer Hülsen aufweist. Eine derartige Transporteinrichtung kann bspw. aus Hängewagenzügen bestehen, die sich vom Flügelbereich der Vorspinnmaschine zu einem Wechselbereich erstreckt, in dem in diesen Hängewagenzügen volle Spulen gegen leere Hülsen ausgewechselt werden. Sie sieht vor, dieser Transporteinrichtung jeder Vorspinnmaschine eine nur ihr zugeordnete Einrichtung zum Entfernen von Vorgarnresten von ausgelaufenen Vorgarnhülsen zuzustellen.The aim of the invention was to clean the empty tubes of roving residues with less effort in planning work, components and control technology. The invention is based on a roving machine which has an internal transport device for conveying full bobbins and empty sleeves. Such a transport device can consist, for example, of suspension trolley trains, which extends from the wing area of the roving machine to an interchangeable area, in which full spools are exchanged for empty tubes in these suspension trolley trains. It provides for this transport device for each roving machine to be provided with a device which is only assigned to it for removing roving remnants from spun roving sleeves.

Es kann sich hierbei um eine selbständige Einrichtung handeln, die am Verlauf der Transportvorrichtung der Vorspinnmaschine angeordnet ist. Bevorzugt ist jedoch vorgesehen, daß die Einrichtung in dem Sinne in die Vorspinnmaschine integriert ist, daß sie eine Baugruppe der Vorspinnmaschine darstellt, die von deren Maschinenrahmen getragen und deren Steuerung von der Steuerung der Vorspinnmaschine aus erfolgt oder zumindest eine Schnittstelle zur Steuerung der Vorspinnmaschine aufweist.This can be an independent device which is arranged on the course of the transport device of the roving machine. However, it is preferably provided that the device is integrated in the roving machine in such a way that it represents a subassembly of the roving machine which is carried by its machine frame and is controlled by the control of the roving machine or at least has an interface for controlling the roving machine.

Wenn die Einrichtung zum Entfernen von Vorgarnresten am Transportweg leerer Hülsen von der Bestückungsstelle der Transportvorrichtung zu der der Bestückungsstelle nächstgelegenen Wechsel-Vorhaltestellung einer leeren Hülse angeordnet ist, wird der Vorteil erreicht, daß dem Wechselbereich der Vorspinnmaschine nur gereinigte Hülsen zugeführt werden und daß die ausgetauschten Hülsen nicht zusätzlich bewegt werden müssen, um sie der Reinigungseinrichtung zuzuführen.If the device for removing roving residues on the transport path of empty sleeves is arranged from the assembly point of the transport device to the change-holding position of an empty sleeve closest to the assembly site, the advantage is achieved that only cleaned sleeves are fed to the changing area of the roving machine and that the exchanged sleeves do not have to be additionally moved to feed them to the cleaning device.

Eine besonders ökonomische Arbeitsweise der Einrichtung zum Entfernen von Vorgarnresten wird dann erreicht, wenn sie nur an mit Vorgarnresten belegten leeren Hülsen tätig wird. Dies kann mittels eines Fühlers erreicht werden, der vorgarnrestfreie zugeführte leere Hülsen fühlt und mit der Einrichtung derart wirkverbunden ist, daß er sie an derartigen leeren Hülsen nicht tätig werden läßt. Die Anordnung kann jedoch auch so getroffen sein, daß der Fühler in Abhängigkeit von der erfaßten Menge an Vorgarnrest den Reinigungsablauf optimiert, d.h. nicht hastig durchführt, wenn die zur Verfügung stehende Zeit dies nicht erfordert.A particularly economical mode of operation of the device for removing roving residues is achieved if it only works on empty sleeves covered with roving residues. This can be achieved by means of a sensor which senses empty sleeves supplied without roving residue and is so operatively connected to the device that it does not allow it to act on such empty sleeves. However, the arrangement can also be such that the sensor optimizes the cleaning process depending on the amount of roving residue detected, i.e. not hastily performing if the time available does not require it.

Da es vorkommen kann, daß die Einrichtung zum Entfernen von Vorgarnresten an einzelnen leeren Hülsen Vorgarnreste nicht vollständig entfernen kann und/oder die Zeit, die der Einrichtung zu diesem Entfernen von Vorgarnresten im Blick auf ihre Integration in den Verfahrensablauf zur Verfügung steht, begrenzt ist, ist eine Möglichkeit vorgesehen, den Ablauf nicht durch derartige Hülsen zu behindern. Diese Möglichkeit besteht in einem Fühler, der nicht oder jedenfalls in der verfügbaren Zeit nicht vollständig von Vorgarnresten zu befreiende Vorgarnhülsen fühlt, einem Magazin, das vorgarnrestfreie leere Hülsen vorhält und einer Vorrichtung, die an den betreffenden Positionen eine nicht vollständig von Vorgarnresten zu befreiende Vorgarnhülse auswirft und durch vorgarnrestfreie leere Hülse aus dem Magazin ersetzt.Since it is possible that the device for removing roving residues from individual empty sleeves cannot completely remove roving residues and / or the time which is available to the device for this removal of roving residues in terms of their integration into the process sequence is limited, a possibility is provided not to hinder the process by such sleeves. This possibility consists in a sensor which does not feel roving sleeves which are not, or at least in the available time, free of roving residues, a magazine which holds empty roving sleeves free of roving residue and a device which ejects a roving sleeve which is not completely free of roving residues at the positions concerned and replaced by empty sleeve from the magazine without roving residue.

Die Einrichtung zum Entfernen von Vorgarnresten kann in beliebiger bekannter Form ausgeführt sein. Sie kann dazu eingerichtet sein, Vorgarnreste abzusaugen, abzuspulen, abzubürsten, abzustreifen oder sonst auf geeignete Weise ohne Beschädigung der Hülse von dieser zu entfernen.The device for removing roving residues can be designed in any known form. It can be set up to suck off roving residues, unwind, brush off, stripped or otherwise removed in a suitable manner without damaging the sleeve.

Die Fühler können ebenfalls in beliebiger bekannter Form ausgeführt sein. Sie können optoelektronische, mit Reflexfolien auf den Hülsen zusammenwirkende Fühler oder Videoüberwachungsgeräte sein. Der Abtastbereich der Fühler liegt vorteilhaft in dem Bereich, von dem aus die Wicklung ihren Anfang nimmt, bei mit Klettband ausgestatteten Hülsen unmittelbar am Klettband.The sensors can also be designed in any known form. They can be optoelectronic sensors interacting with reflective foils on the sleeves or video surveillance devices. The sensing range of the sensors is advantageously in the area from which the winding begins, in the case of sleeves equipped with Velcro, directly on the Velcro.

Wie aus Fig. 1 erkennbar, verlaufen durch den Flügelbereich 2 einer Vorspinnmaschine 1, der ein Kannenfeld 3 zugeordnet ist, zwei Hängebahnen 4 und 5, in denen in den Fig. 1 bis 3 nicht dargestellte Hängewagenzüge verfahrbar sind, mittels derer in der Vorspinnmachine volle Spulen gegen leere Hülsen auswechselbar sind. Bauart und Wirkungsweise einer derartigen Spulenwechselvorrichtung sind aus der DE 42 29 296 A1 bekannt, auf die insoweit Bezug genommen wird. Die Hängebahnen 4, 5 sind über Verbindungsbahnen 6 und Weichen 7 mit einer Ringhängebahn 8 verbunden, deren beide Trume 9 und 10 sich parallel hinter der Vorspinnmachine 1 erstrecken.As can be seen from FIG. 1, two overhead conveyors 4 and 5 run through the wing area 2 of a roving machine 1, to which a can field 3 is assigned, in which suspension trolley trains (not shown in FIGS. 1 to 3) can be moved, by means of which full runners in the roving machine Coils can be exchanged for empty tubes. The type and mode of operation of such a bobbin changing device are known from DE 42 29 296 A1, to which reference is made in this respect. The suspension tracks 4, 5 are connected via connecting tracks 6 and switches 7 to a ring suspension track 8, the two strands 9 and 10 of which extend parallel behind the roving machine 1.

Im Bereich dieser Ringhängebahn 8 ist ein Umsetzer 11 angeordnet, der volle Spulen aus in der Ringhängebahn umlaufenden Hängewagenzügen in in einer weiteren Hängebahn 12 geführte Hängewagenzüge und leere Hülsen aus Hängewagenzügen dieser Hängebahn in Hängewagenzüge der Ringhängebahn umsetzt. Die weitere Hängebahn 12 führt in einen nicht dargestellten Verarbeitungs- oder Lagerbereich. Dieser Verarbeitungsbereich kann aus Ringspinnmaschinen bestehen, in deren Gattern die vollen Spulen abgearbeitet werden und als leere Spulen zur Vorspinnmachine 1 zurückkehren. Der Lagerbereich kann in einer Anordnung von Hängebahnabschnitten bestehen, in der Hängewagenzüge mit vollen Spulen oder mit leeren Hülsen bis zur weiteren Bearbeitung abgestellt werden.In the area of this ring monorail 8, a converter 11 is arranged, which converts full spools of hanging trolley trains running in the ring monorail into another monorail 12 and empty sleeves made of monorail trains of this monorail in monorail trains of the ring monorail. The further monorail 12 leads into a processing or storage area, not shown. This processing area can consist of ring spinning machines, in the gates of which the full bobbins are processed and return to the spinning machine 1 as empty bobbins. Of the The storage area can consist of an arrangement of overhead conveyor sections, in which overhead trolley trains can be parked with full spools or with empty sleeves until further processing.

Um Vorgarnreste, die sich noch auf den in der Hängebahn 12 zurückgeführten und vom Umsetzer 11 auf die Ringhängebahn 8 umgesetzten leeren Hülsen befinden, von diesen zu entfernen, ist eine Einrichtung 13 zum Entfernen von Vorgarnresten - im folgenden kurz Reinigungsvorrichtung genannt - vorgesehen. In der Ausführungsform der Fig. 1 ist diese Reinigungsvorrichtung 13 getrennt von der Vorspinnmachine 1 am Verlauf der Ringhängebahn 8 angeordnet. Es ist davon ausgegangen, daß die Hängewagenzüge beim Umsetzvorgang in der Ringhängebahn in dem Uhrzeigersinn entgegengesetzer Richtung umlaufen. Die Reinigungsvorrichtung 13 ist daher in Laufrichtung der Hängewagenzüge unmittelbar nach dem Umsetzer 11 in die Ringhängebahn 8 eingestellt.In order to remove roving residues that are still on the empty sleeves that are returned in the overhead conveyor 12 and converted from the converter 11 to the ring suspension conveyor 8, a device 13 for removing roving residues - hereinafter called cleaning device for short - is provided. In the embodiment of FIG. 1, this cleaning device 13 is arranged separately from the roving machine 1 on the course of the ring suspension track 8. It has been assumed that the suspension trolley trains rotate in the counterclockwise direction during the transfer process in the ring suspension track. The cleaning device 13 is therefore set in the direction of travel of the suspension trolley trains immediately after the converter 11 in the ring suspension track 8.

In der Ausgangslage befinden sich in der Ringhängebahn 8 zwei mit leeren Hülsen bestückte Hängewagenzüge, die zum Wechselvorgang in die Hängebahnen 4 bzw. 5 im Flügelbereich der Vorspinnmachine 1 eingefahren werden. Nach dem Wechselvorgang in der in der DE 42 29 296 A1 näher beschriebenen Weise werden die nunmehr mit vollen Spulen bestückten Hängewagenzüge wieder in die Ringhängebahn 8 zurückgefahren.In the starting position there are two suspension trolley trains equipped with empty sleeves in the ring suspension track 8, which are inserted into the suspension tracks 4 and 5 in the wing area of the roving machine 1 for the changing process. After the changing process in the manner described in DE 42 29 296 A1, the suspension trolley trains, which are now equipped with full bobbins, are moved back into the ring suspension track 8.

Zum Umsetzen laufen die Hängewagenzüge in der Ringhängebahn 8 entgegen dem Uhrzeigersinn um, wobei der Umsetzer 11 jeweils eine oder zwei volle Spulen aus einem Hängewagenzug in der Ringhängebahn in einen Hängewagenzug der Hängebahn 12 und eine oder zwei leere Spulen aus einem Hängewagenzug der Hängebahn 12 in einen Hängewagenzug der Ringhängebahn 8 umsetzt. Nach dem Umsetzen in einen Hängewagenzug der Ringhängebahn 8 passieren die leeren Hülsen die Reinigungsvorrichtung 13 und werden dabei von verbliebenen Vorgarnresten befreit, sodaß sich in den Hängewagenzügen in der Ringhängebahn 8 nur vorgarnrestfreie leere Hülsen befinden. Es versteht sich, daß die Reinigungsvorrichtung 13 beim Vorbeilauf von mit vollen Spulen bestückten Hängewagenzügen nicht tätig wird.For the transfer, the overhead trolley trains run counterclockwise in the ring suspension track 8, the converter 11 each having one or two full spools from a suspension trolley train in the ring suspension track into a suspension trolley train of the suspension track 12 and one or two empty spools from a suspension trolley train of the suspension track 12 in one Hanging carriage train of the ring suspension railway 8 implements. After being converted into a hanging trolley train of the ring suspension track 8, the empty sleeves pass the cleaning device 13 and are thereby freed of remaining roving residues, so that there are only empty sleeves free of roving residue in the hanging trolley trains in the ring suspension track 8. It goes without saying that the cleaning device 13 does not operate when passing overhead trolleys with full bobbins.

Die Reinigungsvorrichtung 13 ist zwar von der Vorspinnmachine 1 getrennt, jedoch durch das Anordnen an der Ringhängebahn 8 der Vorspinnmachine nur dieser zugeordnet und reinigt nur leere Hülsen an dieser Vorspinnmachine. Die Reinigungsvorrichtung 13 ist autark, d.h. in ihrem Aufbau, ihrer Energieversorgung usw. völlig selbständig und in der Steuerung ihrer Arbeitsweise nur vom Umlauf der leeren Hülsen in der Ringhängebahn 8 abhängig. Sie kann daher ohne weiteres als Option zur Vorspinnmachine 1 angeboten oder auch nachträglich einer Vorspinnmachine zugestellt werden.The cleaning device 13 is indeed separate from the roving machine 1, but is only assigned to the roving machine by arranging it on the ring suspension track 8 and only cleans empty tubes on this roving machine. The cleaning device 13 is self-sufficient, i.e. in its structure, its energy supply etc. completely independently and in the control of its operation only depends on the circulation of the empty sleeves in the ring overhead conveyor 8. It can therefore be offered as an option for the roving machine 1 or can also be subsequently delivered to a roving machine.

In der Ausführungsform der Fig. 2 ist die Reinigungsvorrichtung 13 in die Vorspinnmachine 1 integriert, d.h. sie ist konstruktiv und funktionsmäßig Teil der Vorspinnmachine. Die Ringhängebahn 8 ist zu diesem Zweck durch das Maschinengestell 14 der Vorspinnmachine geführt. Die Steuerung der Arbeitsweise der Reinigungsvorrichtung 13 erfolgt allerdings auch in diesem Falle nur indirekt von der Vorspinnmachine 1 aus nach Maßgabe der Bewegung der Hängewagenzüge mit leeren Hülsen in der Ringhängebahn 8. Der Umlauf der Hängewagenzüge in der Ringhängebahn 8 erfolgt hier im Uhrzeigersinn.In the embodiment of Fig. 2, the cleaning device 13 is integrated in the roving machine 1, i.e. it is constructively and functionally part of the roving machine. For this purpose, the ring suspension track 8 is guided through the machine frame 14 of the roving machine. In this case, however, the mode of operation of the cleaning device 13 is also controlled only indirectly from the pre-spinning machine 1 in accordance with the movement of the hanging trolley trains with empty sleeves in the ring overhead conveyor 8. The circulation of the hanging trolley trains in the ring suspended conveyor 8 takes place here clockwise.

In der Ausführungsform der Fig.3 weist die Vorspinnmachine 1 eine Spulenwechselvorrichtung auf, bei der die Hängebahnen 4 und 5 nicht in eine Ringhängebahn münden, sondern in je eine Parkbahn 15 bzw. 16 verlängert sind. Unterhalb dieser Parkbahnen 15, 16 ist in einer heb- und senkbaren Bank 17 eine endlose Kette 18 geführt, die volle Spulen aus in den Parkbahnen stehenden Hängewagenzügen übernimmt bzw. leere Hülsen in diese Hängewagenzüge einklinkt. Die endlose Kette 18 ist zum Umsetzer 11 geführt, der wie vorstehend beschrieben den Austausch der vollen Spulen und leeren Hülsen in die bzw. aus der Hängebahn 12 vornimmt.In the embodiment of FIG. 3, the roving machine 1 has a bobbin changing device in which the suspension tracks 4 and 5 do not open into a ring suspension track, but rather are each extended into a parking track 15 and 16, respectively. Beneath these parking tracks 15, 16, an endless chain 18 is guided in a bank 17 that can be raised and lowered, which takes over full spools of hanging trolley trains standing in the parking tracks or latches empty sleeves into these hanging trolley trains. The endless chain 18 is guided to the converter 11, which, as described above, exchanges the full bobbins and empty tubes into and out of the overhead conveyor 12.

Die Reinigungsvorrichtung 13 ist hier ebenfalls als Teil der Vorspinnmachine 1 ausgebildet und so angeordnet, daß die Kette 18 durch diese Reinigungsvorrichtung verläuft. Die Kette 18 läuft hier ebenfalls im Uhrzeigersinn um.The cleaning device 13 is here also formed as part of the pre-spinning machine 1 and arranged so that the chain 18 runs through this cleaning device. The chain 18 also rotates clockwise here.

In Fig. 4 ist bei 9 eine Schiene der Ringhängebahn 8 oder eine der Parkbahnen 15, 16 dargestellt, in der ein Hängewagenzug 19 mittels Rollenpaaren 20 verfahrbar ist. Das Verfahren wird durch Reibradpaare 21 bewirkt, die durch Elektromotoren 22 antreibbar sind. An dem Hängewagenzug 19 hängen mittels Hängehaltern 23 leere Hülsen 24, die noch Vorgarnreste 25 aufweisen. Die leeren Hülsen 24 können in der Arbeitsposition mittels eines durch einen Elektromotor 26 antreibbaren Rollenpaares 27 in Drehung versetzt werden.In FIG. 4, a rail of the ring suspension track 8 or one of the parking tracks 15, 16 is shown at 9, in which a suspension carriage train 19 can be moved by means of pairs of rollers 20. The method is brought about by pairs of friction wheels 21 which can be driven by electric motors 22. 23 empty sleeves 24, which still have roving residues 25, hang on the hanging wagon train 19 by means of hanging brackets. The empty sleeves 24 can be set in rotation in the working position by means of a pair of rollers 27 which can be driven by an electric motor 26.

Am Bewegungsweg der leeren Hülsen 24 ist eine sich über die ganze Bewicklungshöhe der Hülse erstreckende Saugdüse 28 angeordnet, die über eine rotierende Siebtrommel 29 mit einer Saugzugquelle in Form eines über einen Elektromotor 30 angetriebenen Ventilators 31 verbunden ist. Es kann jedoch auch eine schmale und damit eine höhere Saugwirkung ausübende, der Absaugstelle nachgeführte Saugdüse verwendet werden. Insbesondere ist jedoch vorgesehen, in Abhängigkeit von der zur Verfügung stehenden Taktzeit mehr als nur ein Absaugaggregat, bspw. deren zwei nebeneinander einzusetzen, so daß jeweils zwei Hülsen gleichzeitig abgesaugt werden können. Der Drehantrieb der Siebtrommel 29 ist hier der Übersichtlichkeit halber nicht dargestellt. Unterhalb der Siebtrommel 29 befindet sich ein Auffangbehälter 32 für abgesaugte Vorgarnfäden.Arranged on the path of movement of the empty sleeves 24 is a suction nozzle 28 which extends over the entire winding height of the sleeve and is connected via a rotating sieve drum 29 to a suction source in the form of a fan 31 driven by an electric motor 30. However, it is also possible to use a narrow suction nozzle which follows the suction point and thus exerts a higher suction effect. In particular, it is provided, depending on the available cycle time, to use more than just one suction unit, for example two of them next to one another, so that two sleeves can be suctioned off simultaneously. The rotary drive of the screen drum 29 is not shown here for the sake of clarity. Below the screening drum 29 there is a collecting container 32 for drawn roving threads.

Am Bewegungsweg der leeren Hülsen 24 ist ferner ein optoelektronischer Fühler 33 angebracht, der die vorbeilaufenden leeren Hülsen 24 auf das Vorhandensein von Vorgarnresten 25 abtastet. Der Fühler 33 kann auf ein Klettband 34 auf der Hülse gerichtet und so ausgebildet sein, daß er den Farb- oder Helligkeitsunterschied zwischen einem vorgarnrestfreien bzw. einem mit Vorgarn belegten Klettband erkennen kann. Der Fühler 33 kann jedoch auch auf eine auf der Hülse angeordnete Reflexfolie 35 gerichtet und so ausgebildet sein, daß er den Unterschied zwischen einer vorgarnrestfreien bzw. einer mit Vorgarn belegten Reflexfolie erkennen kann.An optoelectronic sensor 33 is also attached to the path of movement of the empty sleeves 24 and scans the empty sleeves 24 passing by for the presence of roving residues 25. The sensor 33 can be directed onto a Velcro strip 34 on the sleeve and can be designed such that it can recognize the difference in color or brightness between a Velcro strip that is free of roving residues and a Velcro strip that is covered with roving. However, the sensor 33 can also be directed at a reflective film 35 arranged on the sleeve and can be designed in such a way that it can recognize the difference between a reflective film which is free of roving residues and a reflective film which is covered with roving.

Der Fühler 33 ist mit einer Steuervorrichtung 36 verbunden, die den Elektromotor 22 des Reibradpaares 21, den Elektromotor 26 des Rollenpaares 27 und den Elektromotor 30 des Ventilators 31 steuert.The sensor 33 is connected to a control device 36 which controls the electric motor 22 of the friction wheel pair 21, the electric motor 26 of the pair of rollers 27 and the electric motor 30 of the fan 31.

Fig. 5 zeigt eine Stelle am Bewegungsweg der leeren Hülsen in der Reinigungsvorrichtung 13, an der eine Hülsenaustauschvorrichtung 37 angeordnet ist. Diese Stelle kann mit derjenigen, an der die Absaugvorrichtung angeordnet ist, identisch sein. Bevorzugt ist aber vorgesehen, die beiden Bearbeitungsstellen entlang des Bewegungsweges der Hülsen versetzt anzuordnen, insbesondere deshalb, weil auch bei mehreren Absaugstellen in der Regel nur eine Austauschstelle vorgesehen ist. Die Hülsenaustauschvorrichtung 37 besteht aus einem mittels eines Elektromotors 38 in seiner Längsmitte um eine senkrechte Achse um 180° schwenkbaren, doppelarmigen Schwenkarm 39, an dessen Enden Hülsengreifer 40 in Form von Zapfen angeordnet sind, die von unten in die rohrförmigen Hülsen eintreten können. Der Schwenkarm 39 ist ferner mittels eines weiteren Elektromotors 41, der mit einem Ritzel 42 in eine Zahnstange 43 eingreift, heb- und senkbar.5 shows a point on the path of movement of the empty sleeves in the cleaning device 13, at which a sleeve exchange device 37 is arranged. This point can be identical to that at which the suction device is arranged. However, it is preferably provided that the two processing points are arranged offset along the path of movement of the sleeves, in particular because even if there are several suction points, as a rule only one exchange point is provided. The sleeve exchange device 37 consists of a double-arm swivel arm 39 which can be swiveled by 180 ° in its longitudinal center about a vertical axis by means of an electric motor 38 and at the ends of which sleeve grippers 40 are arranged in the form of pins which can enter the tubular sleeves from below. The swivel arm 39 can also be raised and lowered by means of a further electric motor 41, which engages with a pinion 42 in a rack 43.

Dem Schwenkarm 39 ist ein Leerhülsenmagazin 44 in Form einer mittels eines Elektromotors 45 drehbaren Scheibe 46 zugeordnet, an der mittels Hängehaltern 23 vorgarnrestfreie leere Hülsen 24 vorgehalten werden. Der Hülsenaustauschvorrichtung 37 ist ein Fühler zugeordnet, bei dem es sich um den gleichen Fühler 33 handeln kann, der im Zusammenhang mit der Reinigungsvorrichtung 13 beschrieben ist. Der Fühler ist wiederum mit einer Steuervorrichtung verbunden, bei der es sich ebenfalls um die bereits beschriebene Steuervorrichtung 36 handeln kann. Die Steuervorrichtung 36 ist hier noch mit den Elektromotoren 38, 41 und 45 verbunden.An empty sleeve magazine 44 in the form of a disk 46 which can be rotated by means of an electric motor is assigned to the swivel arm 39, on which empty sleeves 24 free of roving residue are kept by means of hanging holders 23. A sensor is assigned to the sleeve exchange device 37, which can be the same sensor 33 that is described in connection with the cleaning device 13. The sensor is in turn connected to a control device, which can also be the control device 36 already described. The control device 36 is still connected to the electric motors 38, 41 and 45 here.

Beim Vorbeilauf der Hängewagenzüge 19 im Zuge des Auswechselns voller Spulen gegen leere Hülsen durch den Umsetzer 11 am Fühler 33 tastet dieser die leeren Hülsen 24 auf verbliebene Vorgarnreste ab. Wenn er einen Vorgarnrest erkennt, setzt er über die Steuervorrichtung 34 durch Ansteuern des die Reibradpaare 21 antreibenden Elektromotors 22 den Hängewagenzug so still bzw. verhindert er dessen Weiterlauf, daß sich die Hülse vor der Saugdüse 28 befindet. Gleichzeitig schaltet er den Elektromotor 26 des Rollenpaares 27 und den Elektromotor 30 des Ventilators 31 ein, sodaß die verbliebenen Vorgarnreste von der bzw. den in Arbeitsstellung stehenden leeren Hülse abgerollt und abgesaugt werden.When the hanging carriage trains 19 pass by in the course of replacing full bobbins with empty tubes by the converter 11 on the sensor 33, the sensor scans the empty tubes 24 for remaining roving residues. If he detects a roving residue, he sets the suspension trolley train so quietly via the control device 34 by actuating the electric motor 22 driving the friction wheel pairs 21 or prevents it from continuing to run so that the sleeve is located in front of the suction nozzle 28. At the same time, he switches on the electric motor 26 of the pair of rollers 27 and the electric motor 30 of the fan 31, so that the remaining roving residues are unrolled from the empty sleeve or in the working position and suctioned off.

Die abgesaugten Vorgarnreste fallen von einem gegen den Saugzug abgedeckten Bereich der Siebtrommel 29 in den Auffangbehälter 32 ab. Falls mehrere Absaugstellen 37 vorgesehen sind, erfolgen diese Schritte parallel an allen Absaugstellen.The sucked-off roving residues fall from an area of the sieve drum 29 covered against the suction draft into the collecting container 32. If several suction points 37 are provided, these steps take place in parallel at all suction points.

Die Reinigungsvorrichtung 13 kann während einer abgemessenen Zeitdauer auf eine leere Hülse einwirken, die normalerweise ausreicht, verbliebene Vorgarnreste zu entfernen. Es ist jedoch auch möglich, in nicht näher dargestellter Weise in der Saugdüse 28 bzw. in einem an sie anschließenden Kanal einen bspw. optoelektronischen Fühler anzuordnen, der anspricht, wenn kein Vorgarn mehr abgesaugt wird und im Gefolge dessen das Absaugen beendet. Wenn der Fühler 33 nach Ablauf der vorgesehenen Zeit feststellt, daß die leere Hülse doch noch Vorgarnreste enthält, veranlaßt er den Ersatz dieser offenbar nicht selbsttätig oder nicht in der vorgesehenen Taktzeit vollständig zu reinigenden Hülse durch eine vorgarnrestfreie Hülse aus dem Leerhülsenmagazin 44. Zu diesem Zweck veranlaßt die Steuervorrichtung 36 durch Einschalten des Elektromotors 41 Anheben und Senken des Schwenkarmes 39 und damit Ausklinken der vorgarnrestbehafteten leeren Hülse aus dem Hängewagenzug 19 und einer vorgarnrestfreien leeren Hülse aus dem Leerhülsenmagazin 44. Durch Einschalten des Elektromotors 38 wird der Schwenkarm 39 um eine halbe Umdrehung gedreht und damit die erfaßten Hülsen rochiert. Durch erneutes Einschalten des Elektromotors 41 wird der Schwenkarm wieder gehoben und gesenkt und damit die leeren Hülsen in den Hängewagenzug 19 bzw. in das Leerhülsenmagazin 44 eingeklinkt.The cleaning device 13 can act on an empty sleeve for a measured period of time, which is normally sufficient to remove remaining roving residues. However, it is also possible to arrange, for example, an optoelectronic sensor in the suction nozzle 28 or in a channel adjoining it in a manner not shown, which responds when no roving is sucked off and, as a result, the suction stops. If the sensor 33 determines after the allotted time that the empty tube still contains roving residues, it causes the replacement of this tube, which obviously does not have to be cleaned automatically or cannot be cleaned completely within the intended cycle time, by a tube free of roving residue from the empty tube magazine 44. For this purpose causes the control device 36 by switching on the electric motor 41 lifting and lowering the swivel arm 39 and thus disengaging the empty sleeve with roving residue from the hanging trolley 19 and an empty sleeve with no roving residue from the empty sleeve magazine 44. By switching on the electric motor 38, the swing arm 39 is rotated by half a turn and thus castles the captured sleeves. When the electric motor 41 is switched on again, the swivel arm is raised and lowered again, and the empty sleeves are thus latched into the hanging trolley train 19 or into the empty sleeve magazine 44.

Durch Einschalten des Elektromotors 45 wird anschließend die Scheibe 46 um eine Teilung weitergedreht und damit eine neue vorgarnrestfreie leeren Hülse in die Wechselposition gebracht. Die vorgarnbehaftete leere Hülse kann von Hand aus dem Leerhülsenmagazin 44 entnommen, gereinigt und wieder in das Leerhülsenmagazin eingehängt werden.By switching on the electric motor 45, the disk 46 is then rotated further by one division and thus a new empty sleeve free of roving residue is brought into the change position. The empty sleeve with roving can be removed from the empty sleeve magazine 44 by hand, cleaned and hung again in the empty sleeve magazine.
