Description

Die Erfindung betrifft ein Verfahren zum Wechseln von Vorgarnspulen an mindestens einer Textilmaschine gemäss dem Oberbegriff des Anspruches 1. Die Erfindung betrifft ebenfalls eine Vorrichtung zur Durchführung dieses Verfahrens gemäss dem Oberbegriff des Anspruches 6.The invention relates to a method for changing roving bobbins on at least one textile 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 6.

Obgleich viele mögliche Ausführungen und Vorschläge existieren, kann die Verbindung bzw. Verknüpfung zwischen einer Vorspinnmaschine bzw. einem Flyer und einer Spinnmaschine noch nicht als zufriedenstellend angesehen werden. So gibt es bereits Vorgarnspulen fassende Trägerzüge, die auf Hängeschienen vom Flyer vor das Gatter einer Spinnmaschine mit einer beispw. 4-reihigen Aufsteckung längs vorfahren. Aus diesem eine Reservereihe darstellenden Trägerzug müssen die vollen Spulen nach Entfernung der (nahezu) leeren Hülsen auf die Produktionsreihen umgesteckt werden, was eine mühsame, manuelle Arbeit darstellt. Das Umstecken kann, zulasten einer grösseren Investition, auch von einem längs der Maschine am Boden verfahrbaren, eigens für diesen Zweck konzipierten Automaten bewältigt werden, was jedoch nur auf die äussere Produktionsreihe möglich ist. Deshalb ist noch ein weiterer, über dem Gatter verfahrbarer Automat notwendig, der bei laufender Lunte die Spulen der inneren Reihe mit denen der äusseren Reihe umtauscht.Although there are many possible designs and proposals, the connection or link between a roving machine or a flyer and a spinning machine cannot yet be regarded as satisfactory. There are already roving bobbins that take roving bobbins and slide forward on hanging rails from the flyer in front of the gate of a spinning machine with an example of 4 rows. After removing the (almost) empty cores, the full spools have to be transferred from this carrier train, which represents a spare row, to the production rows which is a tedious, manual job. At the expense of a larger investment, the change of plug can also be managed by a machine that can be moved along the machine on the floor and is specially designed for this purpose, but this is only possible for the outer production series. This is why another automatic machine that can be moved over the gate is required, which exchanges the coils of the inner row with those of the outer row while the fuse is running.

Der CH-PS 555902 ist eine Hängeschienenanordnung zu entnehmen, die ein Umstecken unnötig macht und bei welcher Trägerzüge in das Gatter längs eingefahren werden, wobei eine aufwendige Höhenverstelleinrichtung wegen der höhenmässigen Behinderungen des Antriebs- und des Endkopfes der Spinnmaschine notwendig ist. Aber auch einem Längseinfahren ohne Höhenverstellung, z.B. durch eine niedrigere Antriebskopfauslegung, stehen mehrere Nachteile gegenüber. Eine Automatisierung ist hier nämlich unumgänglich, da die Trägerzüge der inneren Reihen sonst nicht verfahrbar sind. Staub- und Flockengebilde können unbemerkbar von den langen Trägerzügen herabfallen und sich in Streckwerke festsetzen und von den Spulen herabhängende Luntenenden können Spinnmaschinenteile streifen, sodass Schäden nicht auszuschliessen sind. Weiter ist ein gleichzeitiges Ansetzen der Lunten innert nützlicher Frist nur mit einer hohen augenblicklichen Personalkonzentrierung zu bewältigen. Auch die Zeitspanne, die notwendig ist für das Trennen der laufenden Lunten einer ganzen Spulenlängsreihe, für das Ausfahren der leeren Hülsen und für das Einfahren der vollen Spulen ist schwer verkürzbar und kann eine Stillsetzung der Maschine notwendig machen. Besonders bei einer 6-reihigen Aufsteckung wäre ein Trägerzug wegen Verbauung durch laufende Lunten ohne zusätzliche Massnahmen nicht verfahrbar.The CH-PS 555902 shows a hanging rail arrangement which makes it unnecessary to change the plug and in which carrier trains are inserted lengthways into the creel, an expensive height adjustment device being necessary because of the height-related disabilities of the drive and end heads of the spinning machine. However, there are also several disadvantages to longitudinal entry without height adjustment, for example due to a lower drive head design. Automation is inevitable here, since otherwise the carrier trains of the inner rows cannot be moved. Dust and flakes can fall unnoticeably from the long girder trains and become lodged in drafting systems, and sliver ends hanging from the spools can graze spinning machine parts, so that damage cannot be ruled out. Furthermore, a simultaneous application of the fuses within a useful period of time can only be managed with a high instantaneous concentration of personnel. The time that is necessary for separating the running fuses of an entire longitudinal coil row, for extending the empty tubes and for retracting the full bobbins is difficult to shorten and can be one Make machine shutdown necessary. Especially with a 6-row attachment, a carrier train would not be able to move without additional measures due to obstruction by running fuses.

Die DE-OS 3034477 offenbart eine Spulenwechselanlage, bei welcher mit Spulen bestückte Träger von einer sich längs einer Maschine erstreckenden Transporthängebahn seitlich in Richtung der Maschinenmittelebene in die Arbeitspositionen der Spulen geführt werden, derart, dass die Längsachse jedes Trägers immer parallel zur Transporthängebahn bleibt und dass Spulenlängsreihen sektionsweise ersetzt werden. Dazu ist eine konstruktiv aufwendige Umdisponier- und Seitenverschiebungseinrichtung mit pro Träger zwei um 90 Grad drehbaren, die Enden des Trägers gleichzeitig erfassenden Haltevorrichtungen notwendig. Das Ein- und Ausbringen der mittleren Spulenlängsreihen ist kompliziert und zeitaufwendig. Die vorliegende Erfindung setzt sich zum Ziel, die eingangs erwähnten Nachteile zu vermeiden und ein Verfahren und eine Vorrichtung vorzuschlagen, die ein manuelles Umstecken der Spulen vermeiden, eine einfache, kostengünstigere Anlage, ein schnelleres Wechseln der Spulen, eine Vermeidung von Arbeitsspitzen während des Spulen- bzw. Luntenwechsels, eine handbetriebene als auch eine automatisierte Arbeitsweise und einen betriebssichereren Spulenwechsel ermöglichen. Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale der Ansprüche 1 und 6. Dadurch, dass die Träger nunmehr, statt seitlich parallel verschoben, seitlich in das Maschinengatter einfahren werden, entfallen Seitenverschiebeeinrichtungen, was sich kostensparend auswirkt, da lediglich Einschienenbahnabzweigungen vorgesehen werden müssen. Weil nur jeweils eine Spulenquerreihe ausgewechselt wird, ist nur eine kleinere Anzahl von Luntenenden auf einmal zu wechseln, was mit lediglich von einer or zwei Bedienungspersonen schnell bewältigt werden kann. Somit entstehen auch keine Arbeitsspitzen mit der Notwendigkeit eines zeitweiligen Personalstaus. Das Fortbewegen der Träger bzw. des Trägerzuges kann leicht von einer Person, mittels beispielsweise eines herabhängendes Organs, ausgeführt werden, aber einer Automatisierung mit beispielsweise Reibtransportrollen und automatischen Kupplungs- und Entkupplungsorganen steht nicht im Wege. Eine Bedienungsperson kann eine Spulenquerreihe bezüglich herunterfallender Flugansammlungen und schleifender und sich verheddender Luntenenden leichter als eine Spulenlängsreihe überwachen, sodass die Betriebssicherheit während des Spulenwechsels als grösser eingestuft werden muss. Anspruch 2 schlägt eine Richtungsänderung zwischen 45 Grad und 90 Grad vor, wovon eine Richtungsänderung von entweder 45 Grad (dies entspricht einem Neigungswinkel, in Bewegungszuführrichtung gesehen, zwischen der Bahnabzweigung und der Transporthängebahn von 135 Grad) oder 90 Grad am zweckmässigsten sind. Für die 90 Grad-Variante spricht eine quer zur Maschinenmittelebene ausgerichtete, herkömmliche Spulenquerreihe, für die 45 Grad-Variante ein leichteres Einfahren eines Trägers wegen des kleineren Bogens und eine Reduzierung der Maschinenbreite, was besonders bei einer 6-reihigen Aufsteckung wichtig sein kann. Das Merkmal des Anspruches 5 ermöglicht die Verwendung von dickeren Spulenpackungen. Die Vorschläge gemäss den weiteren Ansprüchen vervollständigen mindestens eine der gestellten Teilaufgaben. Die Erfindung wird nachfolgend an einer Spinn- bzw. Zwirnmaschine näher erläutert. Es zeigen schematisch

DE-OS 3034477 discloses a bobbin changing system in which carriers equipped with bobbins are guided laterally from a transport suspension track extending along a machine in the direction of the machine center plane into the working positions of the bobbins, such that the longitudinal axis of each support always remains parallel to the transport suspension track and that Longitudinal spool rows are replaced section by section. This requires a structurally complex rescheduling and lateral displacement device with two holding devices that can be rotated by 90 degrees per carrier and simultaneously capture the ends of the carrier. The insertion and removal of the middle longitudinal rows of coils is complicated and time-consuming. The aim of the present invention is to avoid the disadvantages mentioned at the outset and to propose a method and a device which avoid manual repositioning of the coils, simple, more cost-effective installation, faster changing of the coils, avoidance of working peaks during the winding. or change of sliver, a manual as well as an automated mode of operation and a more reliable spool change. The object is achieved by the characterizing features of claims 1 and 6. The fact that the carriers are now moved laterally into the machine frame instead of being moved laterally in parallel eliminates side shifting devices, which has a cost-saving effect since only Monorail branches must be provided. Because only one coil transverse row is exchanged at a time, only a small number of match ends need to be changed at once, which can be quickly accomplished with just one or two operators. This means that there are no work peaks with the need for a temporary personnel backlog. The movement of the carrier or the carrier train can easily be carried out by one person, for example by means of a hanging organ, but automation does not stand in the way of, for example, friction transport rollers and automatic coupling and decoupling elements. An operator can monitor a transverse row of coils more easily than a longitudinal row of coils with regard to falling flight accumulations and grinding and wedging sliver ends, so that the operational safety during the coil change must be classified as greater. Claim 2 proposes a change in direction between 45 degrees and 90 degrees, of which a change in direction of either 45 degrees (this corresponds to an angle of inclination, seen in the direction of movement, between the web junction and the transport monorail of 135 degrees) or 90 degrees are most appropriate. The 90 degree variant is supported by a conventional coil transverse row oriented transversely to the machine center plane, the 45 degree variant is easier to retract a carrier because of the smaller arc and a reduction in the machine width, which can be particularly important with a 6-row attachment. The feature of claim 5 enables the use of thicker coil packages. The proposals according to the other claims complete at least one of the presented Subtasks. The invention is explained in more detail below on a spinning or twisting machine. They show schematically

Fig 1 zeigt eine mit einer 4-reihigen Aufsteckung versehene Spinnmaschine 2 mit einem Antriebskopf 3, einem Endkopf 4 und einem Gatter 5. Längs der Maschine 2 und parallel zu der Maschinenmittelebene 8 erstreckt auf jeder Maschinenlängsseite eine Transporthängebahn 9, die mit um 90 Grad zur Maschinenmittelebene 8 geneigten und bis an die Maschinenmittelebene 8 reichenden Bahnabzweigungen 10 über Weichen 11 verbunden ist. Die Transporthängebahnen 9, deren Längenabschnitte durch Linienunterbrechungen in der Zeichnung angedeutet sind, und die Bahnabzweigungen 10 erstrecken sich im wesentlichen in einer horizontaler Ebene einschliesslich einer evtl. leichten, abwärts gerichteten Neigung der Bahnabzweigungen 10 zur Maschinenmittelebene 8 und auf einer den normalen Arbeitspositionen der Vorgarnspulen 14 entsprechenden Höhe. In einer Flyerbeschickungsstation 16 eines Flyers 17 werden auf einer Kreislaufhängebahn 18 befindliche Träger bzw. Trägerorgane, Trolleys, Fahrgestelle, Laufwagen 20 mit vollen Vorgarnspulen 14.1 bestückt und mittels lösbarer Kupplungen 22 zu einem Trägerzug 21 formiert. Die Trägerzüge 21 werden automatisch mittels Treibradantriebe oder Förderketten oder von Hand mittels beispielsweise eines vom Träger 20 herabhängenden Haltegriffs auf die Transporthängebahnen 9 geführt. Bei Neubestückung der Maschine 2 wird eine lösbare Kupplung 22 gelöst bzw. entkoppelt, die Weiche 11 umgestellt und ein Träger mit zwei vollen Spulen 14.1 wird gemäss dem die Einfahrtrichtung darstellenden Pfeil 23 auf die pro Spulenquerreihe separate Bahnabzweigung 10 geführt bzw. eingefahren. Nach Verbindung der Lunten wird der nächste Träger 20 vom Trägerzug 21 gelöst und auf die folgende Bahnabzweigung 10 geführt. So werden auf einmal nur zwei volle Vorgarnspulen 14.1 bis zu einem an jeder Bahnabzweigung befestigten Endanschlag 26 eingefahren, wobei sich ein Umstecken der Spulen erübrigt, da die am den Endanschlägen 26 anliegenden Träger 20 hängenden Spulen 14 auf der Bahnabzweigung 10 sich in ihren Arbeitspositionen befinden. Wenn eine Maschinenlängsseite bedient worden ist, kann die Bedienungsperson die Spulen auf der anderen Maschinenlängsseite in ihre Arbeitspositionen plazieren. Eine Bahnabzweigung 10 führt also über die Arbeitspositionen einer Spulenquerreihe und deren Länge ist abhängig vom Abstand der Transporthängebahn 9 zur Maschinenmittelebene 8. In Betrieb müssen zuerst die leeren Vorgarnspulen 14.2 gemäss einem Pfeil 27 entgegen der Einfahrtrichtung auf die gleiche Transporthängebahn 9 ausgefahren werden bevor die vollen Vorgarnspulen 14.1 eingefahren werden können, sodass die Transporthängebahnen 9 in diesem Fall je eine gemeinsame An- und Abtransporthängebahn 9.1 darstellt. Die leeren Vorgarnspulen 14.2 werden wieder vorzugsweise mittels selbstkoppelnder Kupplungen 22 zu einem Trägerzug 21 formiert, der zu der Flyerbeschickungsstation 16 geführt wird. Es versteht sich, dass das Hängetransportsystem eine oder mehrere Passierhängebahnen 29 oder sonstige Ausgestaltungen aufweisen kann.1 shows a spinning machine 2 provided with a 4-row attachment, with a drive head 3, an end head 4 and a gate 5. Along the machine 2 and parallel to the machine center plane 8, a transport suspension track 9 extends on each machine longitudinal side, which is at 90 degrees to Machine center plane 8 inclined and reaching to the machine center plane 8 path branches 10 is connected via switches 11. The transport monorails 9, the length sections of which are indicated by line breaks in the drawing, and the rail branches 10 extend in the essentially in a horizontal plane including a possibly slight, downward inclination of the web branches 10 to the machine center plane 8 and at a height corresponding to the normal working positions of the roving bobbins 14. In a flyer loading station 16 of a flyer 17, carriers or support members, trolleys, chassis, carriages 20, which are located on a circular overhead conveyor 18, are filled with full roving bobbins 14.1 and formed into a carrier train 21 by means of detachable couplings 22. The carrier trains 21 are automatically guided onto the transport suspension tracks 9 by means of drive wheel drives or conveyor chains or by hand, for example by means of a handle hanging from the carrier 20. When the machine 2 is re-equipped, a releasable coupling 22 is released or decoupled, the switch 11 is switched over and a carrier with two full spools 14.1 is guided or retracted according to the arrow 23 representing the direction of entry onto the separate path branch 10 per transverse row of spools. After the fuses have been connected, the next carrier 20 is detached from the carrier train 21 and guided to the following path branch 10. In this way, only two full roving bobbins 14.1 are retracted up to an end stop 26 fastened to each web branch, whereby the bobbins do not have to be repositioned, since the bobbins 20 hanging on the end stops 26 on the web branch 10 are in their working positions. When one machine long side has been operated, the operator can place the coils on the other machine long side in their working positions. A path branch 10 thus leads over the working positions of a row of transverse coils and their The length depends on the distance of the conveyor monorail 9 to the machine center plane 8. In operation, the empty roving bobbins 14.2 must first be extended against the direction of travel onto the same conveyor monorail 9 according to an arrow 27 before the full roving bobbins 14.1 can be retracted, so that the conveyor monorails 9 each represents a common supply and removal monorail 9.1. The empty roving bobbins 14.2 are again preferably formed by means of self-coupling couplings 22 to form a carrier train 21 which is led to the flyer loading station 16. It goes without saying that the hanging transport system can have one or more overhead hanging tracks 29 or other configurations.

Das Ausführungsbeispiel gemäss Fig. 2 weist nur auf einer Maschinenlängsseite eine gemeinsame An- und Abtransporthängebahn 9.1 auf, was dadurch ermöglicht wird, dass die Bahnabzweigungen 10 sich über die ganze Maschinenbreite erstrecken. Der Träger enthält fünf Vorgarnspulen 14. Die Längsachse 30 des Trägers 20 hat von der Transporthängebahn 9 zur Bahnabzweigung 10 eine Richtungsänderung von 90 Grad vollführt.The exemplary embodiment according to FIG. 2 has a common supply and removal monorail 9.1 only on one machine longitudinal side, which is made possible by the fact that the web branches 10 extend over the entire machine width. The carrier contains five roving bobbins 14. The longitudinal axis 30 of the carrier 20 has made a change in direction of 90 degrees from the transport suspension track 9 to the path branch 10.

Fig. 3 zeigt ein Ausführungsbeispiel mit einer getrennten Antransporthängebahn 9.2 und einer getrennten, sich längs der anderen Maschinenlängsseite erstreckenden Abtransporthängebahn 9.3 sodass die Träger 20 in Einfahrtsrichtung, welche ebenfalls der Ausfahrtsrichtung entspricht, wieder ausgefahren werden.3 shows an exemplary embodiment with a separate feed monorail 9.2 and a separate monorail extending along the other side of the machine so that the carriers 20 are extended again in the entry direction, which also corresponds to the exit direction.

In Ausführungsbeispiel gemäss Fig. 4 ist an jeder Maschinenlängsseite eine Antransporthängebahn 9.2 vorgesehen. Eine für beide Maschinenlängsseiten gemeinsame Abtransporthängebahn 9.3 erstreckt sich im Bereich der Maschinenmittelebene 8 und führt über einen Maschinenendteil hinweg. Der Maschinenendteil ist wegen der meist niedrigeren Bauhöhe der Antriebskopf 3, aber selbstverständlich kann dies auch der Endkopf 4 sein wenn es die Bauhöhe erlaubt.In the exemplary embodiment according to FIG. 4, a conveyor monorail 9.2 is provided on each longitudinal side of the machine. A removal suspension track 9.3 common to both machine longitudinal sides extends in the area of the machine center plane 8 and leads over a machine end part. The machine end part is because of the usually lower height of the drive head 3, but of course this can also be the end head 4 if the height allows.

Fig 5 zeigt eine gemeinsame An- und Abtransporthängebahn 9.1 zwischen zwei einander zugekehrten Maschinenlängsseiten verschiedener Spinnmaschinen 2. Diese Ausführung kann interessant sein, sobald das Problem der Behinderung durch den Wanderbläser gelöst ist.5 shows a common feed and removal monorail 9.1 between two mutually facing longitudinal sides of the machine of different spinning machines 2. This embodiment can be interesting as soon as the problem of the obstruction by the traveling blower is solved.

Die Ausführung gemäss Fig. 6 entspricht derjenigen gemäss Fig. 3 mit dem Unterschied, dass die Richtungsänderung nunmehr 45 Grad (Winkel 35) ist. Der Träger 20 enthält hier sechs Vorgarnspulen 14 und zum besseren Ein- bzw. Ausfahren weist der Träger 20 zwischen den Vorgarnspulen 14 Gelenke 36 auf.The embodiment according to FIG. 6 corresponds to that according to FIG. 3 with the difference that the change in direction is now 45 degrees (angle 35). The carrier 20 here contains six roving bobbins 14 and the carrier 20 has joints 36 between the roving bobbins 14 for better retraction and extension.

In Fig. 7 ist eine dem Ausführungsbeispiel gemäss Fig. 1 ähnliche Anordnung mit einer Schrägeinfahrt gemäss Fig. 6 gezeigt.FIG. 7 shows an arrangement similar to the exemplary embodiment according to FIG. 1 with an inclined entrance according to FIG. 6.

Bis jetzt sind Träger 20 mit in Bewegungsrichtung hintereinander angeordneten Vorgarnspulen 14 beschrieben worden. Eine Spulenquerreihe bis zur Maschinenmittelebene 8 enthält aus praktischen Gründen mindestens zwei Vorgarnspulen 14. Es ist deshalb für das Ausführungsbeispiel gemäss Fig. 1 logisch, Träger 20 mit zwei Vorgarnspulen 14 zu bestücken. Für den Fall, dass zwei Träger 20 mit je einer Vorngarnspule 14 auf die gleiche Bahnabzweigung 10 geführt werden, werden diese zwei Träger im Zusammenhang mit vorliegender Patentanmeldung als einen Träger betrachtet.Up to now, carriers 20 with roving bobbins 14 arranged one behind the other in the direction of movement have been described. For practical reasons, a transverse row of bobbins up to the machine center plane 8 contains at least two roving bobbins 14. It is therefore logical for the exemplary embodiment according to FIG. 1 to have carrier 20 with two roving bobbins 14 equip. In the event that two carriers 20, each with a roving bobbin 14, are guided onto the same web branch 10, these two carriers are considered as one carrier in connection with the present patent application.

Der in Fig. 8 gezeigte Träger für eine Maschine 2 mit einer 4-reihigen Aufsteckung enthält vier Vorgarnspulen 14, die in Bewegungsrichtung in Zweierreihen nebeneinander und bei einer 90-Grad-Richtungsänderung parallel zueinander ausgerichtet angeordnet sind, wie dies auch Fig. 11 gezeigt ist.The carrier shown in FIG. 8 for a machine 2 with a 4-row attachment contains four roving bobbins 14 which are arranged in two rows next to one another in the direction of movement and aligned parallel to one another in the event of a 90 degree change of direction, as is also shown in FIG. 11 .

Die in Fig. 9 gezeigte Spinnmaschine 2 hat eine 5-reihige Aufsteckung. Zwei Vorgarnspulen 14 liegen in Bewegungsrichtung drei Spulen 14 gegenüber, wobei die Vorngarnspule 14 ohne Gegenüber mit der equivalenten Vorgarnspule 14 eines Trägers 20 auf der anderen Maschinenlängsseite beide ihre Arbeitspositionen auf der Maschinenmittelebene 8 haben. Beide Träger 20 sind hier also nicht bis zur Maschinenmittelebene 8, sondern bis in den Maschinenmittelebenebereich verfahrbar.The spinning machine 2 shown in FIG. 9 has a 5-row attachment. Two roving bobbins 14 lie opposite three bobbins 14 in the direction of movement, the roving bobbin 14 without their counterpart with the equivalent roving bobbin 14 of a carrier 20 on the other longitudinal side of the machine both having their working positions on the machine center plane 8. Both carriers 20 are therefore not movable up to the machine center plane 8, but up to the machine center plane area.

Fig. 10 verdeutlicht ein Arbeitsverfahren, demgemässs zum Zwecke eines gegebenenfalls geeigneteren Arbeitsablaufs in jede zweite Bahnabzweigung 10 ein Träger 20 mit vollen Vorgarnspulen 14.1 und in jede dazwischen liegende Bahnabzweigung 10.1 ein Träger mit halbvollen Vorgarnspulen 14.3 gefahren wird. Es ist deshalb zweckmässig, aber nicht notwendig, zuerst alle zweiten Bahnabzweigungen 10 mit vollen Vorgarnspulen 14.1 und erst danach alle dazwischen liegenden Bahnabzweigungen 10.1 mit halbvollen Vorgarnspulen 14.3 zu versehen. Obendrein können bei diesem Verfahren grössere Spulenpackungen, d.h. grössere Durchmesser, zur Anwendung kommen.10 illustrates a working method, accordingly, for the purpose of a possibly more suitable workflow, a carrier 20 with full roving bobbins 14.1 is moved into every second web branch 10 and a carrier with half-full roving bobbins 14.3 into each intermediate web branch 10.1. It is therefore expedient, but not necessary, first to fill all second web branches 10 with full roving bobbins 14.1 and only then to fill all intermediate web branches 10.1 with half-full ones Roving bobbins 14.3. In addition, larger coil packs, ie larger diameters, can be used in this process.

Fig. 11 zeigt einen Träger 20 mit einer Trageplatte bzw. Tragescheibe 40 und mit einer ebenen Anzahl von Rollen 41, die über einer Hängeschiene 42 der Transporthängebahn 9 und der Bahnabzweigung 10 rollen. Unten an der Trägerplatte 40 sind eine gerade oder eine ungerade Anzahl von Hängezapfen 43 zum Tragen der Vorgarnspulen 14 vorgesehen.Fig. 11 shows a carrier 20 with a support plate or support plate 40 and with a flat number of rollers 41, which roll over a hanging rail 42 of the transport monorail 9 and the web branch 10. At the bottom of the carrier plate 40, an even or an odd number of hanging pins 43 are provided for carrying the roving bobbins 14.

Fig. 12 zeigt einen Träger 20 mit einer Trägerplatte 40, die in einer unten offenen Gleitschiene 47 gleitet. Gegebenenfalls kann eine Antriebsreibrolle 48 vorgesehen sein. Unten an der Trägerplatte 40 sind eine gerade oder eine ungerade Anzahl von Hängezapfen 43 vorgesehen.12 shows a carrier 20 with a carrier plate 40 which slides in a slide rail 47 which is open at the bottom. If necessary, a drive friction roller 48 can be provided. An even or an odd number of hanging pins 43 are provided at the bottom of the carrier plate 40.

Fig. 13 zeigt einen Träger 20 mit einem Trägerbügel 50, der mittels eines oder mehrerer Rollen 51 auf einer einen kreisrunden Querschnitt aufweisenden Hänge- bzw. Tragschiene 54 rollen. Am Trägerbügel 50 kann eine hintereinander oder nebeneinander (durch die gestrichelte Spule 14 angedeutet) angeordnete Anzahl von Hängezapfen 43 vorgesehen sein.13 shows a carrier 20 with a carrier bracket 50, which roll by means of one or more rollers 51 on a hanging or support rail 54 having a circular cross section. A number of hanging pins 43 arranged one behind the other or next to one another (indicated by the dashed coil 14) can be provided on the carrier bracket 50.
