Description

Die Erfindung betrifft eine Transportvorrichtung zum Bereitstellen von leeren Spulenhülsen an den Spinnstellen und zum Abtransportieren von vollen Spinnspulen von den Spinnstellen einer doppelseitigen Spinnmaschine, insbesondere einer Ringspinnmaschine.The invention relates to a transport device for providing empty bobbin tubes at the spinning stations and for removing full spinning bobbins from the spinning stations of a double-sided spinning machine, in particular a ring spinning machine.

Bei einer Vorrichtung der eingangs genannten Art, die aus der DE-OS 37 12 027 bekannt ist, sind auf beiden Seiten der Spinnmaschine Transportelemente vorgesehen, die zu einer hin- und hergehenden Bewegung angetrieben sind. Diese Transportelemente nehmen nur in einer Bewegungsrichtung Teller mit, die mit einem nach oben aufragenden Zapfen zur Aufnahme einer Spulenhülse oder einer Spinnspule versehen sind. Den Tellern ist eine Führungsvorrichtung zugeordnet, die U-förmig um die Spinnmaschine geführt ist. Des weiteren sind Mittel zum Zu- und Abführen der Teller von der Transportvorrichtung vorgesehen. Bei der bekannten Spinnmaschine erfolgt der Spulenwechsel automatisch mittels einer Spulenwechseleinrichtung. Das Auswechseln der vollen Spinnspulen gegen leere Spulenhülsen wird zunächst dadurch eingeleitet, daß die Teller mit den leeren Spulenhülsen mittels der Transportvorrichtung derart unterhalb der Spinnstellen positioniert werden, daß die Teller exakt zu den Spinnstellen ausgerichtet werden, damit sie für einen automatischen Spulenwechsel in einer korrekten Position stehen. Ein an der Spulenwechseleinrichtung vorgesehener Spulengreifmechanismus hebt die vollen Spinnspulen von der Spindelbank ab und setzt sie auf eine Hilfszapfenreihe auf, die zwischen der Spindelbank und der Transportvorrichtung angeordnet ist. Auf die freien Spindeln der Spindelbank werden mittels der Spulenwechseleinrichtung dann die leeren abgenommenen Spulenhülsen von den unterhalb der Spinnstelle angeordneten Tellern aufgesetzt.Anschließend werden die vollen Spinnspulen von der Hilfszapfenreihe auf den Zapfen der Teller positioniert. Die mit vollen Spinnspulen versehenen Teller werden dann den Mitteln zum Abführen der Teller von der Transportvorrichtung zugeführt.In a device of the type mentioned, which is known from DE-OS 37 12 027, transport elements are provided on both sides of the spinning machine, which are driven for a reciprocating movement. These transport elements only take plates in one direction of movement, which are provided with an upstanding pin for receiving a bobbin tube or a spinning bobbin. A guide device is assigned to the plates, which is guided in a U-shape around the spinning machine. Furthermore, means are provided for feeding and removing the plates from the transport device. In the known spinning machine, the bobbin change takes place automatically by means of a bobbin changing device. The exchange of the full spinning bobbins for empty bobbin tubes is initially initiated by using the plates with the empty bobbin tubes of the transport device are positioned below the spinning positions in such a way that the plates are exactly aligned with the spinning positions so that they are in a correct position for an automatic spool change. A bobbin gripping mechanism provided on the bobbin changing device lifts the full spinning bobbins off the spindle bank and places them on an auxiliary pin row which is arranged between the spindle bank and the transport device. The empty, removed bobbin tubes from the plates located below the spinning station are then placed on the free spindles of the spindle bank by means of the bobbin changing device. The plates provided with full spinning bobbins are then fed to the means for removing the plates from the transport device.

Bei der EP-A-337 126, welche unter Artikel 54(3) EPÜ fällt, enthält die Transportvorrichtung ein um den Bereich der Spinnstellen einer Ringspinnmaschine herum-geführtes, hochkant stehendes, endloses Band,das mit Mitnehmern für Teller versehen ist. Die Mitnehmer sind so dem Spindelabstand angepaßt, daß sie die Teller beim Spulenwechsel in einer exakten Position anordnen. Im Bereich der Maschinenendgestelle der Ringspinnmaschine sind Umlenkrollen angeordnet. Bei dieser Vorrichtung sind ferner im Bereich wenigstens eines Endes der Ringspinnmaschine Einrichtungen zum Ein- und/oder Ausschleusen der Teller vorgesehen.In EP-A-337 126, which falls under Article 54 (3) EPC, the transport device contains an upright, endless belt which is guided around the region of the spinning positions of a ring spinning machine and is provided with carriers for plates. The drivers are adapted to the spindle distance so that they arrange the plates in an exact position when changing the spool. Deflection rollers are arranged in the area of the machine end frames of the ring spinning machine. In this device, devices for introducing and / or discharging the plates are also provided in the area of at least one end of the ring spinning machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Transportvorrichtung der eingangs genannten Art so auszubilden, daß der automatische Spulenwechsel vereinfacht und der Raumbedarf für die erforderliche Zwischenlagerungseinrichtung erniedrigt ist.The invention has for its object to provide a transport device of the type mentioned in such a way that the automatic spool change is simplified and the space requirement for the required intermediate storage device is reduced.

Diese Aufgabe wird bei einer gattungsgemäßen Transportvorrichtung dadurch gelöst, daß ein endloses, angetriebenes Transportband vorgesehen ist, das hochkant stehend um den Bereich der Spinnstellen der Spinnmaschine geführt ist und an welchem Mitnehmer für Teller angeordnet sind, welche Teller mit einem Zapfen zur Aufnahme von einer Spinnspule versehen sind, und welche Mitnehmer die Teller in einem der Spindelteilung entsprechenden Abstand ausrichten, und daß an den Mitnehmern zur Aufnahme jeweils einer Spulenhülse Zapfen in einem Spindelteilung entsprechenden Abstand angeordnet sind.This object is achieved in a generic transport device in that an endless, driven conveyor belt is provided which stands upright around the area of the Spinning stations of the spinning machine is guided and on which drivers for plates are arranged, which plates are provided with a pin for receiving a spinning bobbin, and which drivers align the plates at a distance corresponding to the spindle pitch, and that on the drivers for receiving a bobbin tube Pins are arranged at a corresponding spacing in the spindle.

Mittels des umlaufenden Bandes und der daran angebrachten Mitnehmer lassen sich die Teller exakt in die gewünschte Position bringen, ohne daß komplizierte Antriebe notwendig sind. Die auf den Mitnehmern angeordneten Zapfen dienen der Zwischenlagerung von vollen Spinnspulen oder leeren Spulenhülsen. Eine derartige Zwischenlagerungseinrichtung ist besonders einfach und kostengünstig herstellbar und besitzt einen sehr geringen Raumbedarf. Insbesondere ist auch der Einsatz bei solchen Spinnmaschinen möglich, bei denen der Spindelabstand der Spinnstellen gering ist.By means of the circulating belt and the drivers attached to it, the plates can be brought exactly into the desired position without the need for complicated drives. The pins arranged on the carriers serve for the intermediate storage of full spinning bobbins or empty bobbin tubes. Such an intermediate storage device is particularly simple and inexpensive to manufacture and requires very little space. In particular, use is also possible in those spinning machines in which the spindle spacing of the spinning positions is small.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß die Zapfen der Mitnehmer höhengleich zu den Zapfen der Teller angeordnet sind. Hierdurch wird der Steuerungsaufwand für die Spulenwechseleinrichtung verringert, da insbesondere gegenüber einer separaten, zwischen der Spindelbank und der Transportvorrichtung angeordneten Hilfszapfenreihe nur die Spindelbank und die Transportvorrichtung angesteuert werden muß.In a further embodiment of the invention it is provided that the pins of the drivers are arranged at the same height as the pins of the plates. As a result, the control outlay for the bobbin changing device is reduced, since, in particular compared to a separate row of auxiliary pins arranged between the spindle bench and the transport device, only the spindle bench and the transport device need to be actuated.

Bei einer vorteilhaften Ausführungsform der Erfindung wird vorgesehen, daß die Mitnehmer als Tragelemente für die Teller ausgebildet sind, wobei jeweils zwei Mitnehmer einen Teller tragen. Hierdurch wird eine weitere Vereinfachung der Transportvorrichtung erzielt, da zusätzliche Führungselemente für die Teller entfallen.In an advantageous embodiment of the invention it is provided that the drivers are designed as supporting elements for the plates, with two drivers each carrying a plate. This further simplifies the transport device, since there are no additional guide elements for the plates.

Bei einer Weiterbildung dieser Ausführungsform ist an den Mitnehmern eine Aufnahmeöffnung vorgesehen, die zur Aufnahme des Randbereiches der Teller ausgebildet ist. In der Transportstellung der Teller wird deren Randbereich in die Aufnahmeöffnung des Mitnehmers eingeführt. Hierdurch wird eine besonders genaue Fixierung der Teller jeweils zwischen zwei Mitnehmern erreicht.In a development of this embodiment, a receiving opening is provided on the drivers, which is used to receive the Edge area of the plate is formed. In the transport position of the plates, their edge area is inserted into the receiving opening of the driver. In this way, a particularly precise fixation of the plates between two drivers is achieved.

Eine Ausgestaltung dieser Ausführungsform sieht vor, daß die Mitnehmer im Querschnitt U-förmig ausgebildet sind, wobei die Aufnahmeöffnung von den U-Schenkeln begrenzt ist.An embodiment of this embodiment provides that the drivers are U-shaped in cross-section, the receiving opening being delimited by the U-legs.

Eine weitere Vereinfachung wird dadurch erreicht, daß die Mitnehmer einteilig mit einem Fußteil zur Befestigung am Transportband ausgebildet sind.A further simplification is achieved in that the drivers are formed in one piece with a foot part for attachment to the conveyor belt.

Um den Bereich der Spinnstellen ist ein endloses, angetriebenes Transportband (4) hochkant stehend geführt. Dem Transportband (4), das vorzugsweise aus Bandstahl hergestellt ist, sind Umlenkrollen (5,6,7,8) zugeordnet, die im Bereich der Maschinenendgestelle (2, 3) angeordnet sind. Der Antrieb des Transportbandes (4) wird über eine Antriebseinheit (9) bewirkt, die im Maschinenendgestell (3) angeordnet ist. Die Antriebseinheit (9) treibt über einen Keilriemen (10) die Umlenkrolle (8) an. Weiterhin ist dem Transportband (4) eine Spanneinrichtung (11) zugeordnet, deren Vorspannkraft einstellbar ist.Fig. 1 shows a schematic representation of a ring spinning machine (1), which has on both sides a large number of spinning stations arranged side by side, between the machine end frames (2, 3) of the ring spinning machine (1) are arranged. An endless, driven conveyor belt (4) is guided upright around the area of the spinning stations. Deflection rollers (5, 6, 7, 8) are assigned to the conveyor belt (4), which is preferably made from steel strip, which are arranged in the area of the machine end frames (2, 3). The conveyor belt (4) is driven by a drive unit (9) which is arranged in the machine end frame (3). The drive unit (9) drives the deflection roller (8) via a V-belt (10). The conveyor belt (4) is also assigned a tensioning device (11), the pretensioning force of which can be adjusted.

Wie aus den Fig. 2 und 3 ersichtlich ist, sind an dem hochkant stehenden Transportband (4) Mitnehmer (12) befestigt. Die Mitnehmer (12) sind für den Transport von Tellern (14) ausgebildet, die eine runde, scheibenförmige Grundplatte (15) aufweisen, an der unter Zwischenschaltung eines Kragens (16) ein Zapfen (17) angebracht ist. Auf diesem Zapfen (17) sind leere Spulenhülsen (18) oder volle Spinnspulen (19) mit ihren Spulenhülsen aufsteckbar. In der Zeichnung nicht näher dargestellt sind Ein- und Ausschleusvorrichtungen, mit denen die Teller (14) dem Transportband (4) zugeführt oder von diesem abgeführt werden können. Mit den Tellern (14) werden leere Spulenhülsen (18) den Spinnstellen der Ringspinnmaschine (1) zugeführt. Beim Spulenwechsel, der in Fig.5 dargestellt ist, werden die vollen Spinnspulen (19) von den Spinnstellen abgenommen und durch die Spulenhülsen (18) ersetzt. Anschließend erfolgt auf den Tellern (14) der Abtransport der vollen Spinnspulen (19).As can be seen from FIGS. 2 and 3, drivers (12) are attached to the upright conveyor belt (4). The drivers (12) are designed for the transport of plates (14) which have a round, disk-shaped base plate (15) on which a pin (17) is attached with the interposition of a collar (16). Empty bobbin tubes (18) or full spinning bobbins (19) with their bobbin tubes can be plugged onto this pin (17). Not shown in the drawing are infeed and outfeed devices with which the plates (14) can be fed to or removed from the conveyor belt (4). With the plates (14) empty bobbin tubes (18) are fed to the spinning positions of the ring spinning machine (1). When changing the bobbin, which is shown in FIG. 5, the full spinning bobbins (19) are removed from the spinning positions and replaced by the bobbin tubes (18). The full spinning bobbins (19) are then removed on the plates (14).

Zur Aufnahme der Teller (14) besitzen die Mitnehmer (12) eine gabelartige, quer zur Laufrichtung des Transportbandes (4) gerichtete Aufnahmeöffnung (20), die den Randbereich der Grundplatten (15) von jeweils zwei Tellern (14) aufnimmt. Im Bereich der Aufnahmeöffnung (20) ist der Mitnehmer (12) U-förmig ausgebildet, wobei die Aufnahmeöffnung (20) von den horizontal gerichteten U-Schenkeln begrenzt ist. Die Grundplatten (15) der Teller (14) liegen an dem vertikalen Steg der Aufnahmeöffnung an und werden von diesem in Laufrichtung des Transportbandes (4) positioniert. An den Mitnehmern (12) ist oben ein Zapfen (21) angeordnet, der höhengleich mit den Zapfen (17) der Teller (14) angeordnet ist. Auf die Zapfen (21) der Mitnehmer (12) sind leere Spulenhülsen (18) oder volle Spinnspulen (19) mit ihren Spulenhülsen aufsteckbar. Die Zapfen (17) der Teller (14) als auch die Zapfen (21) der Mitnehmer (12) sind in einem der Spindelteilung entsprechenden Abstand angeordnet, d.h. in Laufrichtung des Transportbandes (4) sind im Abstand der halben Spindelteilung Zapfen (17) und Zapfen (21) vorhanden.For receiving the plates (14), the drivers (12) have a fork-like receiving opening (20), which is directed transversely to the running direction of the conveyor belt (4) and receives the edge region of the base plates (15) of two plates (14) in each case. The driver (12) is U-shaped in the area of the receiving opening (20), the receiving opening (20) being delimited by the horizontally directed U-legs.

The pins (17) of the plates (14) and the pins (21) of the drivers (12) are arranged at a distance corresponding to the spindle pitch, ie in the direction of travel of the conveyor belt (4) are pins (17) and at a distance of half the spindle pitch Pin (21) available.

In die Aufnahmeöffnung (20) eines Mitnehmers (12) werden die Randbereiche von zwei nebeneinander liegenden Tellern (14) eingeführt. Somit wird jeweils ein Teller (14) von zwei aufeinanderfolgenden Mitnehmern (12) getragen. Die Breite der Mitnehmer (12) ist so gewählt, daß der Randbereich des Kragens (16) des Tellers (14) mit geringem Spiel zwischen zwei nebeneinander angeordneten Mitnehmern (12) liegt.The edge areas of two adjacent plates (14) are inserted into the receiving opening (20) of a driver (12). A plate (14) is thus carried by two successive drivers (12). The width of the drivers (12) is selected so that the edge region of the collar (16) of the plate (14) lies with little play between two drivers (12) arranged next to one another.

Die Befestigung der Mitnehmer (12) am Transportband (4) erfolgt jeweils über ein Fußteil (22), das mittels einer Befestigungsschraube (23) am Transportband (4) befestigt wird. Wie aus Fig. 4 hervorgeht, die einen Längsschnitt durch einen Mitnehmer (12) zeigt, ist das Fußteil (22) einteilig mit dem Mitnehmer (12) ausgebildet. Das Fußteil (22) ist über die Befestigungsschraube (23) mit einem Führungselement (24) verschraubt, das auf der dem Fußteil (22) gegenüberliegenden Seite des Transportbandes (4) angeordnet ist. Sowohl das Fußteil (22) als auch das Führungselement (24), die bevorzugt aus Kunststoff hergestellt sind, dienen der Führung des Transportbandes (4). Hierzu ist ein Führungsprofil (25) vorgesehen, das im Bereich des Transportbandes (4) einen im wesentlichen U-förmigen, nach oben offenen Querschnitt besitzt. In dem Führungsprofil (25) sind das Fußteil (22) und das Führungselement (24) gleitbeweglich geführt. Das Führungsprofil (25) ist an den Längsseiten der Ringspinnmaschine (1) befestigt. An dem Führungsprofil (25) ist weiterhin ein Leitelement (26) vorgesehen, an dessen Führungskante (27) der Randbereich des Kragens (16) des Tellers (14) während des Transports anliegt. Die Fixierung der Teller (14) quer zur Transportrichtung erfolgt somit einerseits durch den Mitnehmer (12) und andererseits durch das Leitelement (26).The drivers (12) are each attached to the conveyor belt (4) by means of a foot part (22) which is attached to the conveyor belt (4) by means of a fastening screw (23). 4, which shows a longitudinal section through a driver (12), the foot part (22) is formed in one piece with the driver (12). The foot part (22) is screwed via the fastening screw (23) to a guide element (24) which is arranged on the side of the conveyor belt (4) opposite the foot part (22). Both the foot part (22) and the guide element (24), which are preferably made of plastic, serve to guide the conveyor belt (4). For this purpose, a guide profile (25) is provided, which in the area of the conveyor belt (4) has an essentially U-shaped cross section that is open at the top. The foot part (22) and the guide element (24) are slidably guided in the guide profile (25). The guide profile (25) is on the long sides of the Ring spinning machine (1) attached. A guide element (26) is also provided on the guide profile (25), on the guide edge (27) of which the edge region of the collar (16) of the plate (14) bears during transport. The plates (14) are thus fixed transversely to the transport direction on the one hand by the driver (12) and on the other hand by the guide element (26).

Wie aus Fig. 3 hervorgeht, sind das Fußteil (22) und das Führungselement (24) mit gleichen Querschnitten ausgeführt. Die dem Transportband (4) zugewandten Anlageflächen des Fußteiles (22) und des Führungselementes (24) sind gekrümmt ausgeführt. Hierdurch wird ein Knicken des Transportbandes (4),insbesondere an den Umlenkrollen (5,6,7,8) der Transportvorrichtung verhindert.3, the foot part (22) and the guide element (24) are designed with the same cross sections. The contact surfaces of the foot part (22) and the guide element (24) facing the conveyor belt (4) are curved. This prevents the conveyor belt (4) from kinking, particularly on the deflection rollers (5, 6, 7, 8) of the transport device.

Anhand der Fig. 5a bis h soll die Funktionsweise der Transportvorrichtung beim Spulenwechsel beschrieben werden. Gemäß Fig.5a führt das Transportband (4) leere Spulenhülsen (18) auf Tellern (14) heran, die jeweils zwischen zwei am Transportband (4) befestigten Mitnehmern (12) gehalten sind. Der Abstand der Zapfen (17) der aufeinanderfolgenden Teller (14) und der Abstand der in der gleichen Reihe angeordneten Zapfen (21) der aufeinanderfolgenden Mitnehmer (12) entspricht jeweils dem Spindelabstand der Spindeln (29) der Spindelbank (28). Die mit jeweils einer leeren Spulenhülse (18) versehenen Teller (14) werden derart unterhalb der Spindelbank (28) angeordnet, daß die leeren Spulenhülsen (18) exakt mit den Spindeln (29) der Spindelbank (28) fluchten. In dieser Position sind die Zapfen (21) der Mitnehmer (12) um eine halbe Spindelteilung versetzt zu den Spindeln angeordnet.The operation of the transport device when changing the bobbin will be described with reference to FIGS. 5a to h. According to Fig.5a, the conveyor belt (4) leads empty spool sleeves (18) on plates (14), which are each held between two carriers (12) attached to the conveyor belt (4). The distance between the pins (17) of the successive plates (14) and the distance between the pins (21) of the successive drivers (12) arranged in the same row each correspond to the spindle spacing of the spindles (29) of the spindle bench (28). The plates (14), each provided with an empty spool sleeve (18), are arranged below the spindle bench (28) in such a way that the empty spool sleeves (18) are exactly aligned with the spindles (29) of the spindle bench (28). In this position, the pins (21) of the drivers (12) are offset by half a spindle pitch from the spindles.

Gemäß Fig. 5b werden die leeren Spulenhülsen (18) mittels eines Greifmechanismus (30) der nicht näher dargestellten Spulenwechseleinrichtung von den Zapfen (17) der Teller (14) angehoben. Das Transportband (4) wird dann gemäß Fig. 5c um eine halbe Spindelteilung in Richtung des Pfeiles (31) gemäß Fig. 5b vorgefahren, so daß die Zapfen (21) der Mitnehmer (12) exakt fluchtend unterhalb der leeren Spulenhülsen (18) angeordnet sind.According to FIG. 5b, the empty bobbin sleeves (18) are lifted from the pins (17) of the plates (14) by means of a gripping mechanism (30) of the bobbin changing device (not shown). The conveyor belt (4) is then according to FIG. 5c by half a spindle pitch in the direction of the arrow (31) according to FIG. 5b moved forward so that the pins (21) of the drivers (12) are arranged exactly in alignment below the empty coil sleeves (18).

Die nächste Phase des Spulenwechsels ist in Fig.5d dargestellt. Der Greifmechanismus (30) der Spulenwechseleinrichtung setzt die leeren Spulenhülsen (18) auf die Zapfen (21) der Mitnehmer (12) ab. Im nächsten Funktionsschritt gemäß Fig. 5e wird der Greifmechanismus (30) von den Kopfenden der leeren Spulenhülsen (18) gelöst und auf das Kopfende der auf den Spindeln (29) angeordneten vollen Spinnspulen (19) aufgesetzt. Dann wird das Transportband (4) aus der Stellung gemäß Fig.5d in Richtung des Pfeiles (32) um eine halbe Spindelteilung zurückgefahren, so daß die Zapfen (17) der Teller (14) exakt mit den Spindeln (29) der Spindelbank (28) fluchten.The next phase of the bobbin change is shown in Fig.5d. The gripping mechanism (30) of the bobbin changing device places the empty bobbin sleeves (18) on the pins (21) of the drivers (12). In the next functional step according to FIG. 5e, the gripping mechanism (30) is released from the head ends of the empty bobbin tubes (18) and placed on the head end of the full spinning bobbins (19) arranged on the spindles (29). Then the conveyor belt (4) is moved back from the position according to FIG. 5d in the direction of arrow (32) by half a spindle pitch, so that the pins (17) of the plates (14) exactly match the spindles (29) of the spindle bench (28 ) align.

In Fig. 5f ist dargestellt, daß anschließend der Greifmechanismus (30) der Spulenwechseleinrichtung die vollen Spinnspulen (19) auf die Zapfen (17) der Teller (14) aufsteckt.Volle Spinnspulen (19) und leere Spulenhülsen (18) sind in dieser Funktionsstellung abwechselnd nebeneinander angeordnet.Anschließend wird gemäß Fig. 5g der Greifmechanismus (30) vom Kopfende der vollen Spinnspulen (19) gelöst. Das Transportband (4) wird dann aus der Stellung gemäß Fig.5f um eine halbe Spindelteilung in Richtung des Pfeiles (32) gemäß Fig. 5f verfahren. In dieser Position fluchten die leeren Spulenhülsen (18) mit den Spindeln (29) der Spindelbank (28). Demgegenüber sind die vollen Spinnspulen (19) gegenüber den Spindeln (29) um eine halbe Spindelteilung versetzt.5f shows that the gripping mechanism (30) of the bobbin changing device then places the full spinning bobbins (19) on the pins (17) of the plates (14). Full spinning bobbins (19) and empty bobbin tubes (18) are in this functional position 5g, the gripping mechanism (30) is then released from the head end of the full spinning bobbins (19). The conveyor belt (4) is then moved from the position shown in FIG. 5f by half a spindle pitch in the direction of the arrow (32) according to FIG. 5f. In this position, the empty spool sleeves (18) are aligned with the spindles (29) of the spindle bank (28). In contrast, the full spinning bobbins (19) with respect to the spindles (29) are offset by half a spindle pitch.

Der Greifmechanismus (30) der Spulenwechseleinrichtung wird auf das Kopfende der leeren Spulenhülsen (18) abgesenkt, ergreift diese und setzt sie auf die Spindel (29) der Spindelbank (28) auf (Fig. 5h). Die auf den Tellern (14) aufgesteckten vollen Spinnspulen (19) werden anschließend in Richtung des Pfeiles (31) zu einer in der Zeichnung nicht dargestellten mit der Transportvorrichtung gekoppelten Ausschleusvorrichtung transportiert.The gripping mechanism (30) of the bobbin changing device is lowered onto the head end of the empty bobbin tubes (18), grips them and places them on the spindle (29) of the spindle bank (28) (FIG. 5h). The full spinning bobbins (19) placed on the plates (14) are then in the direction of the arrow (31) to one not shown in the drawing with the Transport device coupled discharge device transported.
