Abstract

The bobbin change assembly, for a spinning machine, has lateral travel paths to feed full roving bobbins to the creel, and a connected removal path to take the empty bobbins away from the creel, each of the conveyors being fitted with carriers to move the carriers for the full and empty bobbin holders along their tracks.

Description

Die Erfindung betrifft ein Verfahren zum Wechseln von Vorgarnspulen an einer Ringspinnmaschine gemäss dem Oberbegriff des Anspruches 1. Die Erfindung betrifft ebenfalls eine Einrichtung zur Durchführung dieses Verfahrens gemäss dem Oberbegriff des Anspruches 4.The invention relates to a method for changing roving bobbins on a ring spinning machine according to the preamble of claim 1. The invention also relates to a device for carrying out this method according to the preamble of claim 4.

In der nicht vorveröffentlichten EP-A-311 862 sind bereits mehrere einschlägige, auf dem Prinzip des Quereinfahrens der Vorgarnspulen ins Spulengatter basierende Ausführungsbeispiele beschrieben worden. Gemäss dieser Anmeldung müssen die miteinander gekoppelten und mit Vorgarnspulen bestückten Träger entkoppelt werden, bevor sie in die Querbahn eingeführt werden können. Für die Zufuhrstrecke von der Ringspinnmaschine zum Flyer werden sie durch Kopplung wieder zu einem Zug formiert.In EP-A-311 862 , which has not been previously published, several relevant exemplary embodiments based on the principle of the transverse insertion of the roving bobbins into the creel creel have already been described. According to this application, the carriers which are coupled to one another and equipped with roving bobbins must be uncoupled before they can be introduced into the transverse web. For the feed route from the ring spinning machine to the flyer, they are formed into a train again by coupling.

Aus der DE-OS 36 01 832 ist eine gattungsgemäße Transportanlage für die Beschickung von einer Ladestation aus zu einer oder mehreren Spinnmaschinen mit vollen Spulen bekannt. Die Spulen, welche hierbei an unabhängig voneinander auf der Transportbahn beweglichen Hängewagen aufgehängt sind, werden über Verschiebeelemente in eine Umlaufbahn an die Spinnmaschine gebracht. Leergelaufene Hülsen, welche sich in einem Spulengatter der Spinnmaschine befinden, werden manuell oder automatisch gegen volle auf der Umlaufbahn bereitgestellte Reservespulen ausgetauscht. Das heisst, die ausgewechselten leeren Hülsen gelangen dabei in den Transportweg der vollen Reservespulen.From DE-OS 36 01 832 a generic transport system for loading from a charging station to one or more spinning machines with full bobbins is known. The bobbins, which are suspended from hanging carriages that can move independently of one another on the transport path, are brought into an orbit on the spinning machine by means of displacement elements. Empty cores, which are located in a creel of the spinning machine, are exchanged manually or automatically for full reserve coils provided in the orbit. This means that the replaced empty tubes come into the transport path of the full reserve spools.

Wie dieser Austauschvorgang vorgenommen wird, bzw. mit welcher Einrichtung die Durchführung des Spulenwechsels erfolgt, ist aus der Offenlegungsschrift nicht zu entnehmen.How this exchange process is carried out or which device is used to carry out the bobbin change is not apparent from the published patent application.

Somit stellt sich der Erfindung die Aufgabe, ein Verfahren bzw. eine Vorrichtung zu schaffen, womit ein einfacher und problemloser Wechselvorgang der vollen gegen die leeren Spulen ermöglicht wird.Thus, the object of the invention is to create a method and a device which enable a simple and problem-free exchange process of the full against the empty bobbins.

Diese Aufgabe wird gelöst durch die kennzeichnenden Merkmale der Ansprüche 1 und 4. Durch das vorgeschlagene Verfahren bzw. die Vorrichtung für das Verfahren wird ein vollautomatischer und kreuzungsfreier Spulen- bzw. Hülsentransport gewährleistet. Das heisst, die vollen nachgeführten Spulen kreuzen sich beim Wechselvorgang nicht mit dem Abtransport der leeren Hülsen und ermöglichen einen kontinuierlichen und störungsfreien Wechselvorgang.This object is achieved by the characterizing features of claims 1 and 4. The proposed method and the device for the method ensure a fully automatic and cross-free bobbin or tube transport. This means that the full, rewound bobbins do not cross with the removal of the empty tubes during the changing process and enable a continuous and trouble-free changing process.

Die kontinuierliche Beförderung der Träger gemäss Anspruch 2 mit entsprechend abgestimmter Garnpackung der ersten zu der zweiten Gatterreihe trägt ebenfalls zu einem einfacheren und schnelleren Materialfluss bei. Ausserdem herrscht Einbahnverkehr auf den Bahnabzweigungen, wodurch Rangierbewegungen entfallen. Die Garnpackungen der Spulen der ersten Gatterlängsreihe im Gatter können jetzt gemäss Anspruch 2 kleiner gewählt werden als diejenigen der Spulen der zweiten Gatterlängsreihe, sodass, ohne den Spinnbetrieb zu tangieren, genügend Zeit vorhanden ist, Nachschub von Reservespulen auf die Bahnabzweigungen zu führen und deren Luntenanfangsende (manuell) in eine Bereitschaftsstellung zu plazieren. Obwohl für jede Maschinenlängsseite eine separate oder eine einzige, die Maschine U-förmig umgreifende, beide Maschinenlängsseiten bedienende Antransportbahn möglich wäre, ist es nach Anspruch 5 vorteilhaft, die Antransportbahn ringförmig zu gestalten. Durch die Merkmale des Anspruches 6 kann der Nachschub der Reservespule automatisch und zeitgerecht verwirklicht werden. Die Positionierung der Spulen im Gatter braucht somit keine personelle Nachhilfe oder Aufsicht. Die Merkmale des Anspruches 7 erlauben eine einfache Richtungsänderung der Träger, verglichen mit anderen Beförderungsarten, bspw. einer Tragbändertransportart. Durch das Merkmal des Anspruches 8 kann ein separater Richtungsänderungsmechanismus entfallen. Das Merkmal nach Anspruch 9 vereinfacht die Bereitschaftspositionierung des Luntenanfangendes der nachgeschobenen Reservespule und reduziert somit den Personaleinsatz. Hängend transportierte Flyer- bzw. Vorgarnspulen können beim Transport selber, beim Beschleunigen und Abbremsen eines Transportzuges oder bei dem Übergang auf eine andere Transportbahn pendeln und somit auf benachbarte Spulen anschlagen. Dadurch besteht die Gefahr von Lunten- bzw. Vorgarnbeschädigungen, sodass eine schlechte Qualität des resultierenden Fadens oder vermehrte Fadenbrüche die Folge sein könnten. Durch die Lehren der Ansprüche 10 und 11 können diese Nachteile umgangen werden. Auch können die Transportzüge nunmehr schneller fahren und beschleunigen. Die Erfindung wird nunmehr anhand der Zeichnung beschrieben. Es zeigen schematisch:

The continuous conveyance of the carriers according to claim 2 with a correspondingly coordinated yarn package from the first to the second row of gates also contributes to a simpler and faster material flow. Also there is one-way traffic on the railroad branches, which eliminates shunting movements. The yarn packs of the bobbins of the first longitudinal row of gates in the creel can now be selected smaller than those of the bobbins of the second longitudinal row of gates, so that, without affecting the spinning operation, there is sufficient time to feed reserve bobbins onto the web branches and their end of the match ( manually) in a standby position. Although for each machine longitudinal side a separate or a single one, which encompasses the machine in a U-shape and serves both machine longitudinal sides Transport path would be possible, it is advantageous according to claim 5 to make the transport path ring. Due to the features of claim 6, the replenishment of the reserve spool can be realized automatically and on time. The positioning of the coils in the gate therefore does not require any personal tutoring or supervision. The features of claim 7 allow a simple change of direction of the carrier compared to other modes of transport, for example. A conveyor belt type of transport. Due to the feature of claim 8, a separate direction change mechanism can be omitted. The feature according to claim 9 simplifies the standby positioning of the sliver start end of the pushed-in reserve spool and thus reduces the use of personnel. Hanging flyer or roving bobbins can commute during transport themselves, when accelerating and braking a transport train or when changing to a different transport path and thus hit adjacent bobbins. There is a risk of sliver or roving damage, which could result in poor quality of the resulting thread or increased thread breaks. These disadvantages can be avoided by the teachings of claims 10 and 11. The transport trains can now also travel faster and accelerate. The invention will now be described with reference to the drawing. They show schematically:

Die in Fig. 1 voll und in Fig. 2 teilweise gezeigte Ringspinn- oder Zwirntextilmaschine 2 hat ein 6-reihiges Spulengatter für Vorgarnspulen, pro Maschinenlängsseite bestehend aus drei Gatterlängsreihen, und zwar aus einer der Maschinenlängsmittelebene 3 anliegenden 1. Arbeitspositionslängsreihe 4.1, einer 2. Arbeitspositionslängsreihe 4.2 und einer 3. Längsreihe als Reservereihe 4.3. Ein Beförderungsmittel in Form eines hochkant verlaufenden, endlosen Antriebsbandes 6 (auch eine Kette wäre möglich) ist mittels Umlenkrollen 7 horizontal um die Maschine 2 gespannt. Am unteren Ende des Antriebsbandes 6 ist mindestens ein Stossorgan bzw. Stössel, bzw. Fördermittel, bzw. Mitnehmermittel 8 befestigt, das bzw. der mittels Gleitschuhen 10 in gegenüberliegenden Führungsschienen 11 verfahrbar ist. Unterhalb des Schienenpaares 11 ist eine durch Leitbleche 12 gebildete Antransportringbahn 14 angeordnet. Die Leitbleche 12 bilden ein beidseits einer Längsöffnung 13 verlaufendes Schienenpaar, wobei die Längsöffnungen 13 der Quereinfahrtsbahnen 16 in eine identische Längsöffnung 13.1 der Abtransportbahn 15 münden. Eine gerade, in der Maschinenlängsmittelebene 3 und auf gleicher Höhe wie die Antransportbahn 14 liegende Bahn dient als Abtransportbahn 15, die durch identische Leitbleche 12 gebildet ist. Unter einen Winkel von 90 Grad zur Maschinenmittelebene 3 geneigte Bahnabzweigungen 16 (die gleiche Bahnabzweigung bzw. Quereinfahrtsbahn ist in Fig. 2 zweimal dargestellt worden) verbinden die Antransportbahn 14 mit der Abtransportbahn 15. Individuelle, nicht mit anderen Trägern verbindbare, bzw. unkoppelbare, kreisförmige Tragscheiben 17 von Trägern 18 liegen auf den Leitblechen 12 auf, wobei ein zylinderförmiger, zentrischer Führungsansatz 19 abwärts durch die Leitbleche 12 hindurchragt. Pro Träger 18 ist eine Vorgarn- bzw. Luntenspule 20 über ein Verbindungsmittel, einen Hängezapfen 22, an der Führung 19 aufgehängt (Fig. 3). Im unteren Bereich weist die leere Spule bzw. Hülse 20 einen kreisrunden Schutzteller 23 aus einem rückprallfreien Kunststoff auf, dessen Aussendurchmesser 24 geringfügig grösser als der Durchmesser 25 einer grösstmöglichen bzw. vollen Garnpackung 26, jedoch geringfügig kleiner ist als der Aussendurchmesser 27 der Tragscheibe 17. Unterschiede von einigen Millimetern genügen.The ring spinning or twisted textile machine 2 fully shown in FIG. 1 and partially shown in FIG. 2 has a 6-row creel for roving bobbins, consisting of three creel longitudinal rows per machine longitudinal side, namely from a first longitudinal row 4.1 of work positions adjacent to the machine longitudinal center plane 3, a second Working position longitudinal row 4.2 and a third longitudinal row as a spare row 4.3. A means of transport in the form of an upright, endless drive belt 6 (a chain would also be possible) is stretched horizontally around the machine 2 by means of deflection rollers 7. At the lower end of the drive belt 6, at least one pushing element or tappet or conveying means or driving means 8 is fastened, which can be moved in opposite guide rails 11 by means of sliding shoes 10. A feed ring track 14 formed by baffles 12 is arranged below the pair of rails 11. The baffles 12 form a pair of rails running on both sides of a longitudinal opening 13, the longitudinal openings 13 of the transverse entry tracks 16 opening into an identical longitudinal opening 13.1 of the discharge track 15. A straight path lying in the longitudinal plane 3 of the machine and at the same height as the feed path 14 serves as the discharge path 15, which is formed by identical guide plates 12. Path branches 16 inclined at an angle of 90 degrees to the machine center plane 3 (the same path branch or transverse entry path has been shown twice in FIG. 2) connect the feed path 14 to the discharge path 15. Individual, circular, not connectable to other carriers, or uncouplable Carrier discs 17 from Carriers 18 rest on the guide plates 12, with a cylindrical, central guide projection 19 projecting downward through the guide plates 12. A roving spool or sliver bobbin 20 is suspended from the guide 19 via a connecting means, a hanging pin 22, for each carrier 18 (FIG. 3). In the lower area, the empty bobbin or sleeve 20 has a circular protective plate 23 made of a rebound-free plastic, the outer diameter 24 of which is slightly larger than the diameter 25 of a largest or full yarn package 26, but is slightly smaller than the outer diameter 27 of the support disk 17. Differences of a few millimeters are sufficient.

Am Anfang des Spinnbetriebes bzw. in der Arbeitsausgangslage der Maschine 2 befinden sich Spulen 20.1 in der 1. Längsreihe 4.1, alle mit der gleichen Garnpackung, bspw. 1/4 der vollen Garnpackung 26, während alle Spulen 20.2 in der 2. Längsreihe 4.2 3/4 Garnpackung und alle alternativ für Spulen 20.1 und Spulen 20.2 dienenden Reservespulen 20.3 in der 3. Längsreihe 4.3 4/4 Garnpackung aufgewickelt haben (Fig. 2, links). Jeweils eine Spule 20.1, eine Spule 20.2 und eine Spule 20.3 befinden sich auf einer, durch die Arbeitspositionen der Spulen 20.1 und 20.2 und ebenfalls durch die vorgesehene Reserveposition der Spule 20.3 im Gatter führenden Bahnabzweigung 16. Die Bahnabzweigung 16 weist nahe der Antransportbahn 14 ein als Weiche ausgebildetes Eingangssperrmittel 30 und nahe der Abtransportbahn 15 ein Ausgangssperrmittel 31 auf, welche Sperrmittel 30, 31 die drei vorgesehenen Träger 18 der Spulen 20.1, 20.2 und 20.3 im wesentlichen (auf einige Millimeter kommt es nicht an) zusammenhalten. Der Abstand der beiden Sperrmittel 30, 31 kann variieren, je nachdem die Sperrmittel 30, 31 mit den Tragscheiben 17 oder den Führungen 19 der Träger 18 zusammenwirken.At the beginning of the spinning operation or in the starting position of the machine 2 there are bobbins 20.1 in the first longitudinal row 4.1, all with the same yarn package, for example 1/4 of the full yarn package 26, while all the bobbins 20.2 in the second longitudinal row 4.2 3 / 4 yarn package and all reserve bobbins 20.3 serving alternatively for bobbins 20.1 and bobbins 20.2 have been wound up in the 3rd longitudinal row 4.3 4/4 yarn package (FIG. 2, left). In each case one coil 20.1, one coil 20.2 and one coil 20.3 are located on a path branch 16 leading through the working positions of the coils 20.1 and 20.2 and also through the intended reserve position of the coil 20.3 in the gate. The path branch 16 points near the feed path 14 as Soft input blocking means 30 and near the removal path 15 an output blocking means 31, which blocking means 30, 31 essentially hold together the three provided supports 18 of the coils 20.1, 20.2 and 20.3 (it does not matter a few millimeters). The distance between the two locking means 30, 31 can vary depending on the locking means 30, 31 cooperate with the support disks 17 or the guides 19 of the carrier 18.

Pro Bahnabzweigung 16 ist an einer geeigneten Stelle eine drehbare Luntenumlenkstange 33 für die drei Lunten 34.1, 34.2, 34.3 der Spulen 20.1, 20.2 resp. 20.3 vorhanden. Die Luntenumlenkstange 33 hat drei schraubenförmige Windungen bzw. Nuten 35.1, 35.2 und 35.3, die vorteilhafterweise durchgehend ausgebildet sind. Die Lunte 34.1 der Spule 20.1 läuft durch die der Bahnabzweigung 16 am nächsten liegenden Nut 35.1, auch Luntenendposition genannt, zum entsprechenden Streckwerk. Die Lunte 34.2 läuft durch die Nut 35.2 und ebenfalls zum entsprechenden Streckwerk. Die Lunte 34.3 der Reservespule 20.3 liegt in der am weitesten von der Bahnabzweigung 16 liegenden Nut 35.3, auch Luntenanfangsposition genannt, und wird, z.B. in einem Umschaltkondensor 37, in einer Bereitschaftsstellung gehalten. Sobald die Spule 20.1 leer wird, gibt ein das Luntenende der Lunte 34.1 anzeigender Sensor 38 ein Signal 39 an die Luntenumlenkstange 33, an die beiden Sperrmittel 30, 31 und an den Umschaltkondensor 37. Das Sperrmittel 31, hier in Form einer vorteilhafterweise unter den Leitblechen 12 angeordneten und mit der Führung 19 des Trägers 18 zusammenwirkenden Schwenkklappe, entfernt sich aus der Sperrstellung, indem es wegschwenkt. Gleichzeitig schwenkt ein Längsschenkel 41 der Weiche 30 auf (Fig. 2 rechts), dabei die Führung 19 des Trägers 18 einer in Pfeilrichtung 42 kontinuierlich von einem Stössel 8 beförderten, vollen Nachschubreservespule 20.4 erfassend, wodurch die Spule 20.4 auf die Bahnabzweigung 16 gelenkt wird, wobei selbsttätig die Spulen 20.1, 20.2 und 20.3 zur Maschinenmittelebene 3 weitergeschoben werden. Insbesondere wenn andere Mittel als die Weiche 30 benützt werden, bspw. ein in Richtung der Bahnabzweigung 16 bewegbarer Stössel, kann das Antriebsband 6 kurz angehalten werden. Die nunmehr leere Spule 20.1 gelangt auf die Abtransportbahn 15 und ist im leeren Zustand nicht mehr dargestellt. Die Spule 20.2 wird rechts in Fig. 2 mit der Bezugsnummer 20.2.1 bezeichnet und hat nun nur noch 2/4 Garnpackung. Die nach wie vor volle Spule 20.3 gelangt von der 3. Längsreihe 4.3 auf die 2. Längsreihe 4.2, wobei sie jetzt mit der Bezugsnummer 20.3.1 bezeichnet ist, und deren Lunte 34.3 wird durch Umschaltung des Umschaltkondensors 37 abgezogen. Gleichzeitig macht die Luntenumlenkstange 33 eine Drehung, wodurch die Lunten 34.2 und 34.3 nach links zur Bahnabzweigung 16 hin geführt werden. Dadurch wird die Nut 35.3 frei für die neue Lunte der Spule 20.4. Damit die Lunten sich beim Kreuzen nicht behindern, ist mit Vorteil eine durchgehende Luntenkreuzstange 43 vorgesehen.For each path branch 16, a rotatable sliver deflection rod 33 for the three slivers 34.1, 34.2, 34.3 of the coils 20.1, 20.2, respectively. 20.3 available. The sliver deflecting rod 33 has three helical turns or grooves 35.1, 35.2 and 35.3, which are advantageously designed to be continuous. The fuse 34.1 of the spool 20.1 runs through the groove 35.1 closest to the path branch 16, also referred to as the sliver end position, to the corresponding drafting system. The fuse 34.2 runs through the groove 35.2 and also to the corresponding drafting system. The fuse 34.3 of the reserve coil 20.3 lies in the groove 35.3 which is furthest from the web branch 16, also referred to as the match start position, and is held in a ready position, for example in a changeover condenser 37. As soon as the coil 20.1 becomes empty, a sensor 38 which indicates the match end of the match 34.1 gives a signal 39 to the match guide rod 33, to the two blocking means 30, 31 and to the changeover condenser 37. The blocking means 31, here advantageously in the form of the guide plates 12 arranged and cooperating with the guide 19 of the carrier 18 pivot flap removes from the locked position by pivoting away. At the same time, a longitudinal leg 41 of the switch 30 swings open (FIG. 2 on the right), thereby capturing the guide 19 of the carrier 18 of a full supply reserve spool 20.4 which is continuously conveyed in the direction of arrow 42 by a plunger 8, as a result of which the spool 20.4 is directed onto the path branch 16 wherein the coils 20.1, 20.2 and 20.3 are automatically pushed to the machine center level 3. Especially when others When the switch 30 is used, for example a plunger which can be moved in the direction of the path junction 16, the drive belt 6 can be stopped briefly. The now empty spool 20.1 arrives at the removal path 15 and is no longer shown in the empty state. The bobbin 20.2 is designated with the reference number 20.2.1 on the right in FIG. 2 and now only has 2/4 yarn pack. The coil 20.3, which is still full, passes from the 3rd longitudinal row 4.3 to the 2nd longitudinal row 4.2, whereby it is now designated with the reference number 20.3.1, and its fuse 34.3 is removed by switching the switching capacitor 37. At the same time, the match deflecting rod 33 makes a rotation, as a result of which the matches 34.2 and 34.3 are guided to the left towards the path junction 16. This frees the groove 35.3 for the new fuse of the coil 20.4. In order that the fuses do not interfere with the crossing, a continuous crossmember 43 is advantageously provided.

Beim Durchlaufen der Spule 20.3 durch die Weiche 30 drückt die Führung 19 einen Kurzschenkel 45 der Weiche 30 automatisch in ihre Schliessstellung (Fig. 2 links), sodass nachfolgende Träger 18 auf der Antransportbahn 14 gradlining an der Weiche 30 vorbeigeführt werden. Das Ausgangssperrmittel 31 schliesst wieder nach Durchlauf einer Spule. Jeder Träger 18 wird durch einen individuellen Stössel 8 in einer Richtung 42 kontinuierlich befördert. Es ist aber auch möglich, mit einem Stössel 8 eine ganze Gruppe von Trägern 18 vor sich her zu schieben. Zur Reibungsverminderung können die mit den Leitblechen 12 in Berührung kommenden Flächen der Tragscheiben 17 mit eingebetteten Kugeln versehen sein. Der Stössel 8 hat eine in Laufrichtung konisch abgeplattete, sich verjüngende Form, wobei eine der Seitenflächen 48 die vom Längsschenkel 41 eingeleitete Richtungsänderung des Trägers 18 auf die Bahnabzweigung 16 unterstützt bzw. beendet. Obgleich zwei separate, im Maschinenlängsmittelebenebereich befindliche Abtransportbahnen möglich wären, genügt auch eine gemeinsame, zwei Maschinenlängsseiten bedienende Abtransportbahn 15, insbesondere dann, wenn eine Kollisionsgefahr durch eine zeitliche Staffelung vermieden wird. In der Maschinenlängsmittelebene 3 befindet sich ein über Umlenkwalzen 50 laufendes und an seiner Aussenoberfläche lediglich einen einzigen, nierenförmigen, mit der Umfangsfläche der Tragscheiben 17 im Eingriff bringbaren Schieber bzw. Fördermittel 51 aufweisendes Abtransportband 52 oberhalb der Abtransportbahn 15. Die Träger 18 können auf einer Zufuhrstrecke 55 vom Flyer und einer Abfuhrstrecke 56 zum Flyer reibungslos durch eine Tragbändertransporteinrichtung bekannter Art befördert werden. Die Übergabestationen der Transportsysteme sind mit dem Bezugszeichen 57 gekennzeichnet. Die Abfuhrstrecke 56 überquert das Antriebsband 6 mittels einer Steigung. Deshalb kann es notwendig sein, den Rand der Schutzteller 23 dementsprechend anzupassen.When the coil 20.3 passes through the switch 30, the guide 19 automatically presses a short leg 45 of the switch 30 into its closed position (FIG. 2 on the left), so that subsequent carriers 18 are guided straight along the switch 30 on the transport path 14. The output blocking means 31 closes again after passing through a coil. Each carrier 18 is continuously conveyed in one direction 42 by an individual tappet 8. But it is also possible to push a whole group of carriers 18 in front of them with a plunger 8. To reduce friction, the surfaces of the support disks 17 that come into contact with the guide plates 12 can be provided with embedded balls. The plunger 8 has a tapered shape that is flattened conically in the running direction, one of the side surfaces 48 supports or terminates the change in direction of the carrier 18, initiated by the longitudinal leg 41, onto the web junction 16. Although two separate transport lanes located in the machine longitudinal center plane area would be possible, a common transport lane 15 serving two machine longitudinal sides is also sufficient, in particular if a risk of collision is avoided by staggering over time. In the machine longitudinal center plane 3 there is a conveyor belt 52 running above deflection rollers 50 and having only a single kidney-shaped conveyor belt 51 on its outer surface, which can be brought into engagement with the peripheral surface of the support disks 17, above the conveyor path 15. The carriers 18 can be on a feed path 55 from the flyer and a discharge line 56 to the flyer can be conveyed smoothly by a carrier tape transport device of a known type. The transfer stations of the transport systems are identified by reference number 57. The discharge path 56 crosses the drive belt 6 by means of an incline. Therefore, it may be necessary to adjust the edge of the protective plate 23 accordingly.

Die Spulen haben eine ungefähre Aufspulzeit von 3 Std., wonach ein Transportzug bzw. ein Transportschub von bspw. 96 Spulen zu einer Ringspinnmaschine mit bspw. 960 Spinnstellen befördert werden kann. Da die Spulen der 1. Längsreihe 4.1 etwa gleichzeitig leer werden, kann davon ausgegangen werden, dass mit zwei Transportzügen 192 benachbarte Spinnstellen bedient werden. Der Nachschub von Reservespulen für die ganze Ringspinnmaschine braucht somit etwa 30 Std. Da die Spulen eine ungefähre Abspulzeit von 60 Std. haben, können in diesem Fall die Spulen in der 1. Längsreihe 4.1 in der Arbeitsausgangslage eine 1/2 Garnpackung aufgewickelt haben. Das Abtransportband 52 kann erst nach Spulenwechsel eines ganzen Transportzuges in Bewegung gesetzt werden, sodass die leeren Spulen in einem geschlossenen Transportzug wieder zum Flyer befördert werden können. U.U. sind dann keine Pufferzüge notwendig. Natürlich sind viele andere Ausführungsarten denkbar. Es können bspw. mehrere Schieber 51 vorgesehen sein, die Leitbleche 12 können durch Winkeleisen gebildet sein, die Garnpackungen in der 2. Längsreihe 4.2 in der Arbeitsausgangslage können eine maximale Grösse aufweisen, statt der gezeigten Stössel 8 kann unter einem Leitblech 12 eine bewegbare Kette mit Mitnehmerstiften Verwendung finden, zur Verringerung des Aussendurchmessers 27 der Tragscheiben 17 und somit der Breite der Transportbahnen 14, 15 können Zwischenscheiben ohne Spulen zur Anwendung kommen, Neigungsänderungen der Bahnabzweigungen 16 wären ohne weiteres möglich, die Abfuhrstrecke 56 kann unter dem Antriebsband 6 hindurchgeführt werden, die Tragscheiben 17 können hohl ausgebildet oder mit Verstärkungsrippen versehen sein, usw. Auch können die Zufuhrstrecke 55 und die Abfuhrstrecke 56 zu einer gemeinsamen, zwischen dem Flyer und der Ringspinnmaschine verlaufenden Transportbahn vereinigt werden. Auf einer solchen Transportbahn kann ein von einem Trolley bewegbarer Transportzug absenkbare Tragleisten aufweisen, auf welchen die Träger 18 mitgeführt werden, wobei die Träger 18 in der Übergabestation 57 auf die Antransportbahn 14 gebracht werden. Es ist ebenfalls denkbar, überhaupt auf eine Übergabestation 57 für die Zufuhr von vollen Spulen 20 zu verzichten. Im letzteren Fall würde ein Stössel 8 aufweisender Transportzug direkt, vom Flyer kommend, auf die ringförmige Antransportbahn 14 geführt, wobei nur eine Übergabestation 57 für die leeren Hülsen zwischen dem Abtransportband 52 und der Antransportringbahn 14 notwendig ist.The bobbins have an approximate winding time of 3 hours, after which a transport train or a transport thrust of, for example, 96 bobbins can be conveyed to a ring spinning machine with, for example, 960 spinning positions. Since the bobbins of the first longitudinal row 4.1 become empty at about the same time, it can be assumed that adjacent spinning stations are operated with two transport trains 192. The supply of reserve bobbins for the entire ring spinning machine therefore takes about 30 hours. Since the bobbins have an approximate unwinding time of 60 hours, In this case, the bobbins in the first longitudinal row 4.1 in the starting position have wound up a 1/2 package of yarn. The removal belt 52 can only be set in motion after an entire transport train has been changed, so that the empty spools can be conveyed back to the flyer in a closed transport train. Under certain circumstances, no buffer trains are necessary. Of course, many other designs are possible. For example, a plurality of sliders 51 can be provided, the guide plates 12 can be formed by angle irons, the yarn packs in the second longitudinal row 4.2 in the starting position can have a maximum size, instead of the plunger 8 shown, a movable chain can be provided under a guide plate 12 Driving pins are used, in order to reduce the outside diameter 27 of the support disks 17 and thus the width of the transport tracks 14, 15, intermediate disks can be used without coils, changes in the inclination of the track branches 16 would be possible without further ado, the discharge section 56 can be passed under the drive belt 6, which Carrier disks 17 can be hollow or provided with reinforcing ribs, etc. The feed section 55 and the discharge section 56 can also be combined to form a common transport path running between the flyer and the ring spinning machine. On such a transport track, a transport train that can be lowered by a trolley can have support rails on which the supports 18 are carried, the supports 18 being brought to the transport track 14 in the transfer station 57. It is also conceivable to dispense with a transfer station 57 for the supply of full bobbins 20 at all. In the latter case, a tappet 8 would have a transport train coming directly from the flyer, guided onto the ring-shaped feed path 14, only one transfer station 57 being necessary for the empty sleeves between the discharge belt 52 and the feed ring path 14.
