Die in Fig. 1 voll und in Fig. 2 teilweise gezeigte Ringspinn- oder Zwirnmaschine 2 hat ein 6-reihiges Spulengatter für Vorgarnspulen, pro Maschinenlängsseite bestehend aus drei Gatterlängsreihen, und zwar aus einer der Maschinenlängsmittelebene 3 anliegenden ersten Arbeitspositionslängsreihe 4.1, einer zweiten Arbeitspositionslängsreihe 4.2 und einer dritten Längsreihe als Reservereihe 4.3. Ein Beförderungsmittel in Form eines aufstehend 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° 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 dem Führungsansatz 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 twisting machine 2 fully shown in FIG. 1 and partially shown in FIG. 2 has a 6-row creel for roving bobbins, consisting of three rows of longitudinal rows per machine longitudinal side, namely from a first longitudinal longitudinal row 4.1 of the machine longitudinal plane 3, a second longitudinal row 4.2 of working positions and a third longitudinal row as a spare row 4.3. A Conveyor means in the form of an endless drive belt 6 that runs upright (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 driver 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 lanes 16 opening into an identical longitudinal opening 13.1 of the removal path 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. Track branches 16 inclined at an angle of 90 ° to the machine center plane 3 (the same track branch or transverse entry track has been shown twice in FIG. 2) connect the infeed track 14 with the outfeed track 15. Individual, circular carrier disks which cannot be connected or coupled to other carriers 17 of Carriers 18 rest on the guide plates 12, a cylindrical, central guide projection 19 projecting downward through the guide plates 12. For each carrier 18, a roving spool or sliver bobbin 20 is suspended from the guide projection 19 via a connecting means, a hanging pin 22 (FIG. 3). In the lower region, 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, über die Arbeitspositionen der Spulen 20.1 und 20.2 und ebenfalls über die vorgesehene Reserveposition der Spule 20.3 im Gatter hinwegführenden 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 Führungsansätzen 19 der Träger 18 zusammenwirken.At the start 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 bobbins 20.2 are 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 spool 20.1, one spool 20.2 and one spool 20.3 are located on a path branch 16 leading beyond the working positions of the spools 20.1 and 20.2 and also beyond the intended reserve position of the spool 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 the three provided carriers 18 of the coils 20.1, 20.2 and 20.3 together (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 guide lugs 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 nähest zur Bahnabzweigung 16 befindlichen 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 weitest von der Bahnabzweigung 16 befindlichen 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 aus (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 das Eingangssperrmittel 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.At each suitable branch point 16 there is 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, which is also closest to the branch path 16, also referred to as the match 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 spool 20.3 lies in the groove 35.3, also known as the beginning of the fuse position, located furthest from the web branch 16 and is held in a standby 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 deflecting rod 33, to the two blocking means 30, 31 and to the changeover condenser 37. The blocking means 31, here in the form of an advantageously under the guide plates 12 arranged and cooperating with the guide 19 of the bracket 18 pivot flap removes from the locked position by pivoting away. At the same time, a longitudinal leg 41 of the switch 30 swings out (FIG. 2 on the right), thereby capturing the guide 19 of the carrier 18 of a full supply reserve spool 20.4 continuously conveyed by a plunger 8 in the direction of the arrow 42, as a result of which the spool 20.4 is directed onto the web 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 input blocking means 30 are used, for example a plunger which can be moved in the direction of the web branch 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 on the right in FIG. 2 with the reference number 20.2.1 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 rod 33 makes a rotation, whereby 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 das Eingangssperrmittel 30 drückt die Führung 19 einen Kurzschenkel 45 des Eingangssperrmittels 30 automatisch in ihre Schliesstellung (Fig. 2 links), sodass nachfolgende Träger 18 auf der Antransportbahn 14 gradlining an dem Eingangssperrmittel 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, 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, kann mit einer gemeinsamen, zwei Maschinenlängsseiten bedienenden Abtransportbahn 15 ausgekommen werden, insbesondere dann, wenn eine Kollisionsgefahr durch eine zeitliche Staffelung vermieden wird. In der Maschinenlängsebene 3 befindet sich ein über Umlenkwalzen 50 laufendes und an seiner Aussenoberfläche lediglich einen einzigen, nierenförmigen, mit der Umfangsfläche der Tragscheiben 17 in 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 bobbin 20.3 passes through the input blocking means 30, the guide 19 automatically presses a short leg 45 of the input blocking means 30 into its closed position (FIG. 2, left), so that subsequent carriers 18 are guided straight along the input blocking means 30 on the feed 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, wherein one of the side surfaces 48 supports or ends 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 can be used, in particular if a risk of collision is avoided by staggering over time. In the machine longitudinal 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 are 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 transported 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 served with two transport trains 192. The supply of reserve bobbins for the entire ring spinning machine thus takes about 30 hours. Since the bobbins have an approximate unwinding time of 60 hours, In this case, the bobbins in the 1st longitudinal row 4.1 have wound up a 1/2 package of yarn in the starting position. 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, to reduce the outer 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 readily possible, the discharge path 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 onto 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.
