Description

Die Erfindung betrifft eine Spulenwechseleinrichtung für Spuleneinrichtungen mit den Merkmalen im Oberbegriff des Hauptanspruches.The invention relates to a bobbin changing device for coil devices having the features in the preamble of the main claim.

Aus der Praxis sind Spuleinrichtungen, sogenannte Winder, für Teppichgarn bekannt, die mit hoher Geschwindigkeit das Teppichgarn auf zwei hintereinander auf jeweils einem Spuldorn steckende Hülsen zu Spulen wickeln. Der Spulenwechsel wird hierbei von Hand durchgeführt, wobei die fertiggewickelten Spulen über eine Hebeschublade vom Dorn abgezogen und vor dem Winder zur Abholung bereitgelegt werden. Der Bediener nimmt die Spulen ab, legt sie in einen mitgeführten Gitterwagen und steckt im Austausch zwei neue leere Hülsen auf den Spuldorn. Dieser Spulenwechsel ist vom Zeitaufwand und der Betriebssicherheit her problematisch. Die manuelle Abholung muss sehr pünktlich erfolgen, weil der Winder auf einem zweiten Spuldorn bereits das nächste Spulenpaar wickelt. Beim Spulenwechsel bewegen sich außerdem die Spuldorne in einer Bogen- oder Kreisbahn entsprechend der anwachsenden Spulendicke. Problematisch ist auch der Umstand, dass in der Regel mehrere Winder in mehreren Reihen hintereinander und nebeneinander angeordnet sind, deren Spulzeiten sich teilweise überlappen. Außerdem ist häufig nur wenig Platz an den Windern für den Spulwechsel vorhanden. Ungünstig ist ferner der hohe Personalaufwand.From practice winding devices, so-called Winder, for carpet yarn are known to wind at high speed, the carpet yarn on two successively on each one Spülorn pods sleeves. The bobbin change is done here by hand, the finished wound coils are withdrawn via a lifting drawer from the mandrel and prepared for pickup before the winder. The operator removes the bobbins, places them in an entrained lattice cart and, in exchange, puts two new empty pods on the spool. This bobbin change is problematic from the time and reliability. The manual pickup must be done very punctually, because the Winder on a second spool already wrapped the next coil pair. When changing the bobbins also move the spurs in a curved or circular path according to the increasing coil thickness. Another problem is the fact that usually several Winder in several rows are arranged one behind the other and next to each other, whose winding times overlap partially. In addition, there is often little space on the winders for the Spulwechsel available. Unfavorable is also the high personnel costs.

Die nächstliegende US-A-4,621,778 zeigt eine automatische Spulenwechseleinrichtung mit einem einzelnen fahrbaren Hubdoffer, der mehrere Winder bedient und an einer Schienenführung entlang der Winder bewegt werden kann. Der Hubdoffer besitzt eine Spulenwechseleinrichtung, mit der volle Spulen vom Winder abgenommen und Leerhülsen zugeführt werden können. Die Spulenwechseleinrichtung ist mit einem Schlitten an einer vertikalen Säule auf und ab bewegt werden kann. Die Säule ist ihrerseits drehbar mit Drehantrieb auf einem Stützrahmen angeordnet, wobei dieser Rahmen an den Schienen verfahrbar gelagert ist. Durch die Drehbewegung kann die Spulenwechseleinrichtung zwischen den Windern und einer hochliegenden Spulentransportvorrichtung, die an der gegenüberliegenden Seite des Hubdoffers angeordnet ist, hin und her geschwenkt werden.The closest US-A-4,621,778 shows an automatic bobbin changing device with a single wheeled lifting box that can serve multiple winder and move along a rail guide along the winder. Hubdoffer has a bobbin changing device, with the full bobbins removed from the Winder and empty tubes can be supplied. The bobbin changing device can be moved up and down with a carriage on a vertical column. The column is in turn rotatably arranged with rotary drive on a support frame, said frame being movably mounted on the rails. As a result of the rotational movement, the bobbin changing device can be pivoted back and forth between the winders and a high-level bobbin transport device which is arranged on the opposite side of the lifting device.

Die JP-A-08 91 21 89 zeigt einen Hubdoffer mit einem Schlitten und einem Spulenwechsler, der keinen Hülsenwechsler besitzt. Die Hubführung des Schlittens führt auch eine Schwenkbewegung gegenüber dem Winder aus. Durch diese überlagerte Schwenkbewegung während des Schlittenhubs kann nur ein Spulenwechsel, aber kein Hülsenwechsel stattfinden. Die Transporteinrichtung und die Spuleinrichtung sind auf unterschiedlichen Seiten des Hubdoffers angeordnet.JP-A-08 91 21 89 shows a Hubdoffer with a carriage and a bobbin changer, which has no sleeve changer. The lifting guide of the carriage also performs a pivoting movement relative to the winder. By this superimposed pivoting movement during the carriage stroke only a bobbin change, but no change of tube can take place. The transport device and the winding device are arranged on different sides of the Hubdoffers.

Der in der EP 0 534 272 A1 gezeigte Hubdoffer hat eine Vertikalführung mit einem Schlitten, auf dem ein Spulenwechsler und ein Hülsenwechsler angeordnet sind, die miteinander über eine Schwenkeinrichtung mit einer zusätzlichen Horizontalachse gekoppelt sind und dementsprechend nacheinander über eine Schwenkbewegung an die Spuldorne des Winders zugestellt werden. Der vorbekannte Hubdoffer ist verfahrbar und bedient mehrere Winder.The Hubdoffer shown in EP 0 534 272 A1 has a vertical guide with a carriage on which a bobbin changer and a sleeve changer are arranged, which are coupled to each other via a pivoting device with an additional horizontal axis and accordingly delivered successively via a pivoting movement to the winding mandrels of the Winders become. The previously known Hubdoffer is movable and operated several Winder.

Es ist Aufgabe der vorliegenden Erfindung, eine bessere Möglichkeit zum Spulenwechsel aufzuzeigen.It is an object of the present invention to provide a better way to bobbin change.

Die Erfindung löst diese Aufgabe mit einer Spulenwechseleinrichtung mit den Merkmalen im Hauptanspruch.The invention solves this problem with a bobbin changing device with the features in the main claim.

An den verschiedenen Spuleneinrichtungen ist jeweils ein stationär angeordneter Hubdoffer angeordnet, der mit einem Spulenwechsler den Spulenwechsel automatisch durchführt und die fertigen Spulen an eine gemeinsame Transporteinrichtung zur Weiterbeförderung übergibt, welche im Bereich der Spuleneinrichtung hochliegend und außerhalb von deren Arbeitsbereich angeordnet ist. Hierdurch kann der Spulenwechsel sehr schnell vonstatten gehen, wobei die Spulen auch keine größeren Wege zurücklegen müssen. Sie können gleich am Winder an die Transporteinrichtung übergeben werden, so dass der Hubdoffer sofort wieder für den nächsten Spulenwechsel bereitsteht.At the various coil devices, a stationarily arranged Hubdoffer is arranged in each case automatically performs the bobbin change with a bobbin changer and transfers the finished bobbins to a common transport device for further transport, which is located in the region of the coil means high and outside of their working area. As a result, the bobbin change can take place very quickly, and the bobbins do not have to cover any major paths. They can be handed over to the transport device right at the Winder so that the Hubdoffer is immediately ready for the next bobbin change.

Jeder Spuleinrichtung bzw. jedem Winder ist ein eigener Hubdoffer zugeordnet, wobei zumindest die in einer Reihe stehenden Winder eine gemeinsame Transporteinrichtung haben. Hierdurch kann der Spulenwechsel autark erfolgen. Die vorzugsweise als Monorail-System ausgebildete Transporteinrichtung ist dabei auch in der Lage, an verschiedenen Stellen gleichzeitig von Hubdoffern Spulen aufzunehmen.Each winding device or each Winder is assigned its own Hubdoffer, wherein at least the standing in a row Winder have a common transport device. As a result, the bobbin change can be self-sufficient. The transport device, which is preferably designed as a monorail system, is also able to simultaneously receive coils from lifting devices at different points.

Der Spulenwechsler ist mit einem Hülsenmagazin und einem automatischen Hülsenwechsler ausgestattet, so dass auch die Neubestückung mit leeren Hülsen automatisch und ohne manuellen Eingriff erfolgen kann.The bobbin changer is equipped with a sleeve magazine and an automatic tube changer, so that the replacement with empty tubes can be done automatically and without manual intervention.

Der Hubdoffer ist mit einer vorzugsweise vertikalen Stützsäule und einem daran heb- und senkbar verfahrbaren Schlitten ausgerüstet. Durch die exzentrische Positionierung der Stützsäule und die fliegende Schlittenlagerung ist der Zugangsbereich an der Front des Winders und im Bereich der Spuldorne nur während des Spulen-Hülsenwechsels versperrt. Bei der nachfolgenden Übergabe der bewickelten Spulen an die Transportvorrichtung ist der Zugangsbereich wieder frei. Durch die kurzen Taktzeiten beim Spulenwechsel und die schnelle Freigabe des Zugangsbereiches kann ein Bediener rasch wieder an den Winder gelangen, falls an diesem je nach Typ zusätzliche manuelle Arbeiten erforderlich sind, z.B. Einspannen des neuen Fadens an der leeren Hülse oder dgl. Innerhalb der Spulzeit hat der Bediener hierfür wegen der kurzen Spulwechselzeiten auch ausreichend Zeit.The Hubdoffer is equipped with a preferably vertical support column and a lifting and lowering movable carriage. Due to the eccentric positioning of the support column and the flying carriage support, the access area at the front of the Winders and locked in the area of the Spuldorne only during the coil-sleeve change. In the subsequent transfer of the wound coils to the transport device, the access area is free again. Due to the short cycle times when changing the bobbin and the quick release of the access area, an operator can quickly get back to the winder, if this additional manual work is required depending on the type, eg clamping the new thread to the empty sleeve or the like. Within the winding time has the operator also has enough time to do this because of the short reel change times.

Die Spulenwechseleinrichtung kann eine Sicherheitseinrichtung aufweisen, die den Zugang zum Winder nur bei angehobenem Schlitten und nur außerhalb der Spulen- und Hülsenwechselvorgänge an der Maschine freigibt. Dies dient der Unfall- und Betriebssicherheit.The bobbin changing device may comprise a safety device which releases access to the winder only when the carriage is raised and only outside the bobbin and sleeve changing operations on the machine. This serves for accident and operational safety.

Ein besonderer Vorteil der Spulenwechseleinrichtung liegt auch in ihrem geringen Platzbedarf, der eine Anordnung selbst bei enger Anordnung der Winder ermöglicht und zudem nur wenig Platz im Gang zwischen den Winderreihen braucht. Die Spulenwechseleinrichtung lässt sich dadurch an bestehenden Anlagen nachrüsten. Die erfindungsgemäße Spulenwechseleinrichtung erfordert nur einen geringen Bau- und Kostenaufwand. Sie ist hierdurch besonders wirtschaftlich und effizient.A particular advantage of the bobbin changing device is also in their small footprint, which allows an arrangement even with a close arrangement of the winder and also needs little space in the corridor between the rows of winders. The bobbin changing device can be retrofitted to existing systems. The bobbin changing device according to the invention requires only a small construction and cost. This makes it particularly economical and efficient.

In der gezeigten Ausführungsform hat der Winder (2) zwei Spuldorne (7,8), auf denen jeweils zwei Hülsen (21) hintereinander mit Abstand stecken und von rotatorisch angetriebenen Spuldornen (7,8) gedreht werden. Hierfür sind entsprechende Spanneinrichtungen vorhanden. Alternativ können es auch mehr oder weniger Spuldorne (8) sein. Auch die Zahl der hintereinander aufgesteckten Hülsen (21) bzw. Spulen (3) kann variieren.In Figure 1, a bobbin changing device (1) and a winding device (2) is shown partially canceled. The winding device (2) is preferably designed as a so-called. Winder for carpet yarn, but may also have any other configuration. It serves to thread material, i. Yarns, filaments or the like, on empty tubes (21) to wind coils (3). Instead of the sleeves (21), if necessary, also other coil carriers can be used. In the embodiment shown, the winder (2) has two spindles (7, 8), on each of which two sleeves (21) are inserted one behind the other by a distance and are rotated by rotationally driven spinning mandrels (7, 8). For this purpose, appropriate clamping devices are available. Alternatively, there may be more or less spindles (8). Also, the number of consecutively plugged sleeves (21) or coils (3) may vary.

Vorzugsweise sind mehrere Spuleinrichtungen (2) in ein oder mehreren Reihen nebeneinander bzw. hintereinander zu einer Anlage angeordnet. Figur 3 zeigt in der Draufsicht hiervon einen Ausschnitt mit zwei nebeneinander angeordneten Spuleinrichtungen (2).Preferably, a plurality of winding devices (2) are arranged in one or more rows next to one another or behind one another to form a system. Figure 3 shows in plan view thereof a section with two juxtaposed winding devices (2).

Die Spulenwechseleinrichtung (1) besitzt für jede Spuleinrichtung (2) einen eigenen Hubdoffer (4). Dieser besitzt jeweils eine Hubführung (10), die vorzugsweise als im wesentlichen vertikale Stützsäule ausgebildet ist und die seitlich neben dem Zugangsbereich (9) an der Spuleinrichtung (2) angeordnet ist. Sie befindet sich dabei auch seitlich neben dem Bereich der Spuldorne (7,8) und der dortigen Spulen (3). An der Hubführung (10) ist ein Schlitten (12) vorzugsweise fliegend gelagert, der entlang der Hubführung (10) über einen Hubantrieb (11) hin- und herbewegt werden kann, wobei er gehoben und gesenkt wird. Oberhalb der Spuleinrichtung (2) bzw. der Spuldorne (7,8) befindet sich die Transporteinrichtung (5), die im Bereich der Spuleinrichtung (2) und des Hubdoffers (4) angeordnet ist. Der stationär angeordnet Hubdoffer (4) kann die aufgenommenen Spulen (3) an die Transporteinrichtung (5) für die Weiterbeförderung übergeben. Diese Übergabe findet mit Abstand oberhalb oberhalb der Spuldorne (7,8) und außerhalb des Zugangsbereichs (9) an der Front der Spuleinrichtung (2) statt. Figur 1 und 2 zeigen den Schlitten (12) jeweils in der unteren und oberen Position.The bobbin changing device (1) has a separate Hubdoffer (4) for each winding device (2). This has in each case a lifting guide (10), which is preferably designed as a substantially vertical support column and which is arranged laterally next to the access area (9) on the winding device (2). It is also located laterally next to the area of the spool (7,8) and the coils there (3). On the lifting guide (10), a carriage (12) is preferably cantilevered, which can be reciprocated along the lifting guide (10) via a lifting drive (11), wherein it is raised and lowered. Above the winding device (2) or the spool (7,8) is the transport device (5), which is arranged in the region of the winding device (2) and the Hubdoffers (4). The stationarily arranged Hubdoffer (4) can pass the recorded coils (3) to the transport device (5) for further transport. This transfer takes place at a distance above above the spool (7,8) and outside the access area (9) at the front of the winding device (2). Figures 1 and 2 show the carriage (12) respectively in the lower and upper positions.

Jeder Hubdoffer (4) hat einen Spulenwechsler (15), dessen Bestandteile zumindest teilweise am Schlitten (12) angeordnet sind. Der Spulenwechsler (15) weist eine Einrichtung zur Übernahme der fertiggewickelten Spulen (3) von der Spuleneinrichtung (2) und zur Übergabe dieser Spulen (3) an die Transporteinrichtung (5) auf. In der gezeigten Ausführungsform ist hierfür an der Spuleinrichtung (2) eine Überschiebeeinrichtung (17) angeordnet, die nach Lösen der Spannstellung die fertigbewickelten Spulen (3) von den Spuldornen (7,8) an einen Aufnahmedorn (14) am Schlitten (12) und einen dortigen Spulenhalter (18) überschiebt. Am Schlitten (12) ist eine Abschiebeeinrichtung (16) angeordnet, die dann in der oberen, gestrichelt gezeichneten Position die Spulen (3) an die Transporteinrichtung (5) und deren Spulenaufnahme (24) abschiebt. Durch diese getrennte Anordnung der Einrichtungen (16,17) kann der Schlitten (12) sehr leicht und klein bauen. Er hat außerdem wenig bewegte Teile und weniger Antriebe.Each Hubdoffer (4) has a bobbin changer (15) whose components are at least partially disposed on the carriage (12). The bobbin changer (15) has a device for taking over the finished wound bobbins (3) from the bobbin device (2) and for transferring these bobbins (3) to the transport device (5). In the embodiment shown, a sliding device (17) is arranged on the winding device (2) for this purpose, which, after releasing the clamping position, feeds the finished wound coils (3) from the spinning mandrels (7, 8) a receiving mandrel (14) on the slide (12) and a local coil holder (18) overshoots. On the slide (12) a push-off device (16) is arranged, which then pushes off the coil (3) to the transport device (5) and the coil receptacle (24) in the upper dashed position. By this separate arrangement of the devices (16,17), the carriage (12) can build very light and small. He also has few moving parts and fewer drives.

Der Spulenwechsler (15) hat auch einen automatischen Hülsenwechsler (19), der zusammen mit einem Hülsenmagazin (20) für mehrere leere Hülsen (21) am Schlitten (12) angeordnet ist. Mit dem Hülsenwechsler (19) können nach Übernahme der Spulen (3) auf den leeren Spuldorn (7,8) wieder Hülsen (21) aufgesteckt und gespannt werden.The bobbin changer (15) also has an automatic sleeve changer (19) which is arranged together with a sleeve magazine (20) for a plurality of empty sleeves (21) on the carriage (12). With the sleeve changer (19) sleeves (21) can be plugged and tightened again after taking over the coils (3) on the empty spool (7.8).

In der bevorzugten Ausführungsform bestehen die Abschiebeeinrichtung (16) und die Überschiebeeinrichtung (17) vorzugsweise aus gabelförmigen Schiebegreifern, die über Zylinder und Führungen längs der Dorne (7,8,14) fahrbar gelagert sind und die für die jeweilige Überschiebe- bzw. Abschiebebewegung die Spulen (3) hintergreifen und vorzugsweise durch Anlage an die vorstehenden Krägen der Hülsen (21) schieben. Der Spulenhalter (18) kann außerdem eine Verschiebeeinrichtung beinhalten, mit der der Aufnahmedorn (14) horizontal vorund zurückverfahren werden kann, um dicht an die Spuldorne (7,8) bzw. die Spulenaufnahme (24) für die Spulenübergabe anschließen zu können. Eine ähnliche Verschiebeeinrichtung hat auch der Hülsenwechsler (19).In the preferred embodiment, the push-off device (16) and the push-over device (17) preferably consist of fork-shaped sliding grippers, which are movably mounted via cylinders and guides along the mandrels (7, 8, 14) and which for the respective push-on or push-off movement Behind the coils (3) engage and preferably by abutment on the projecting collars of the sleeves (21). The bobbin holder (18) can also include a displacement device with which the receiving mandrel (14) can be moved back and forth horizontally in order to be able to connect tightly to the spool mandrels (7, 8) or the coil receptacle (24) for the spool transfer. A similar displacement device also has the sleeve changer (19).

Die Transporteinrichtung (5) ist vorzugsweise als Monorail-System ausgebildet und übergreift mehrere Spuleinrichtungen (2). Sie besitzt z.B. eine Förderschiene (22), auf der mehrere Transportwagen (23) verfahrbar geführt sind und getrennt voneinander über entsprechende Antriebe bewegt werden können. Jeder Transportwagen (23) hat ein oder mehrere Spulenaufnahmen (24). Wie Figur 1 verdeutlicht, ist die Transporteinrichtung (5) in unmittelbarer Nähe des stationär positionierten Hubdoffers (4) angeordnet. In Figur 2 und 3 ist die Transporteinrichtung (5) bzw. deren Förderschiene (22) durch eine strichpunktierte Linie symbolisiert.The transport device (5) is preferably designed as a monorail system and overlaps a plurality of winding devices (2). It has, for example, a conveyor rail (22) on which a plurality of transport cars (23) movable are guided and can be moved separately from each other via appropriate drives. Each trolley (23) has one or more coil receptacles (24). As Figure 1 illustrates, the transport device (5) in the immediate vicinity of the stationarily positioned Hubdoffers (4) is arranged. In FIGS. 2 and 3, the transport device (5) or its conveyor rail (22) is symbolized by a dot-dash line.

Der Spulprozess findet an der Spuleinrichtung (2) vorzugsweise kontinuierlich statt. Hierbei werden jeweils auf einem Spuldorn (7,8) zwei Spulen (3) aufgewickelt, während der andere Spuldorn (8,7) mit leeren Hülsen (21) für den nächsten Spulvorgang bereitsteht. Hierbei drehen sich die beiden Spuldorne (7,8) auf einer Bogenbahn, insbesondere einer Kreisbahn, um eine zentrale, horizontale Achse. Diese Drehbewegung kann entsprechend des Dickenzuwachses der Spulen (3) erfolgen.The winding process preferably takes place continuously at the winding device (2). In this case, two spools (3) are each wound on a spool (7.8), while the other spool (8.7) is ready with empty sleeves (21) for the next winding process. Here, the two mandrels (7,8) rotate on a curved path, in particular a circular path, about a central, horizontal axis. This rotational movement can take place in accordance with the increase in thickness of the coils (3).

Wenn zwei Spulen (3) fertig bewickelt sind, wird das Fadenmaterial an der Spuleinrichtung (2) in geeigneter Weise, vorzugsweise vollautomatisch, abgeschnitten oder abgetrennt. Die zwei Spulen (3) stehen dann zum Spulenwechsel bereit. Der Hubdoffer (4) hat eine Ruheposition, in der der Schlitten (12) sich in der angehobenen Stellung befindet. Für den Spulenwechsel wird der Schlitten (12) abgesenkt und mit seinem Aufnahmedorn (14) auf Höhe des für den Wechsel bereitstehenden Spulendorn (7) gebracht. Der Aufnahmedorn (14) wird dann dicht an den Spuldorn (7) zugestellt, woraufhin die Überschiebeeinrichtung (17) die zwei Spulen (3) auf den Aufnahmedorn (14) überschiebt. Der Aufnahmedorn (14) fährt in die Ausgangsposition zurück. Anschließend wird der Schlitten (12) ein Stück angehoben, bis das Spulenmagazin (20) und der Spulenwechsler (19) auf Höhe des nun leeren Spuldörnes (7) kommen. Im Magazin (20) liegen mit Abstand unterhalb des Aufnahmedorns (14) zwei leere Hülsen (21) bereit, die nach einer entsprechenden axialen Zustellung dann vom Hülsenwechsler (19) auf den Spuldorn (7) überschoben werden. Der Hülsenwechsler (19) hat hierbei eine Klemmeinrichtung, mit der er nach dem Positionieren der vorderen und der Spuleinrichtung (2) benachbarten Hülse (21) die hintere Hülse klemmt und sich dann mit dieser ein kleines Stück zurückbewegt.,In der Spuleinrichtung (2) kann dann ein am Spuldorn (7) etwa in der Mitte befindlicher Hülsenanschlag ausgefahren werden, gegen welchen der Spulenwechsler (19) dann die hintere Hülse (21) aufschiebt. Durch eine entsprechende Spanneinrichtung am Spuldorn (7) werden dann die leeren Hülsen (21) geklemmt und stehen für den nächsten Wickelvorgang bereit. Der Hülsenwechsler (19) schiebt sich in die Ausgangsstellung zurück, wobei vom Hülsenmagazin (20) zwei neue Hülsen (21) für den nächsten Wechselvorgang bereit gestellt werden. Der Schlitten (12) bewegt sich anschließend nach oben in die Übergabeposition zur Transporteinrichtung (5). Sobald ein Transportwagen (23) bereitsteht, fährt der Spulenhalter (18) den Aufnahmedorn (14) aus und die Abschiebeeinrichtung (16) schiebt eine oder beide Spulen (3) auf die ebenfalls mit einem Dorn versehene Spulenaufnahme (24). Wenn der Transportwagen (23) zwei in Förderrichtung nebeneinander liegende Spulenaufnahmen (24) besitzt, muss er für die Übergabe der zweiten Spule ein Stück nach vorn fahren. Sobald die Spulenübergabe beendet ist, zieht sich der Spulenhalter (18) in die Ausgangsstellung zurück und der Schlitten (12) verharrt in der angehobenen Ruheposition bis zum nächsten Wechselvorgang. Die Transporteinrichtung (5) befördert die übernommenen Spulen (3) dann in beliebig geeigneter Weise weiter zu einem Sammelplatz, einer Weiterverarbeitung oder dergleichen.If two coils (3) are finished wound, the thread material on the winding device (2) in a suitable manner, preferably fully automatically, cut off or separated. The two coils (3) are then ready for bobbin change. The Hubdoffer (4) has a rest position in which the carriage (12) is in the raised position. For the bobbin change of the carriage (12) is lowered and brought with its mandrel (14) at the level of the ready for the change of the bobbin mandrel (7). The receiving mandrel (14) is then delivered close to the spool (7), whereupon the pushing device (17) overshadows the two coils (3) on the mandrel (14). The mandrel (14) moves back to the starting position. Subsequently, the carriage (12) is raised a bit until the reel magazine (20) and the bobbin changer (19) come at the level of the now empty Spuldörnes (7). In the magazine (20) are at a distance below the receiving mandrel (14) two empty sleeves (21) ready, which are then pushed by the sleeve changer (19) on the spool (7) after a corresponding axial delivery. The sleeve changer (19) in this case has a clamping device with which he after positioning the front and the winding device (2) adjacent sleeve (21) clamps the rear sleeve and then moved back a little bit with this., In the winding device (2) can then be extended to the spool (7) located approximately in the middle sleeve stop against which the bobbin changer (19) then pushes the rear sleeve (21). By a corresponding clamping device on the spool (7) then the empty sleeves (21) are clamped and are ready for the next winding process. The sleeve changer (19) slides back into the starting position, wherein the sleeve magazine (20) two new sleeves (21) are provided for the next change process. The carriage (12) then moves upward into the transfer position to the transport device (5). As soon as a transport cart (23) is ready, the bobbin holder (18) moves out the receiving mandrel (14) and the push-off device (16) pushes one or both bobbins (3) onto the bobbin holder (24), which is also provided with a mandrel. If the trolley (23) has two adjacent in the conveying direction coil housings (24), he has to drive for the transfer of the second coil a bit forward. Once the bobbin transfer is completed, the bobbin holder (18) retracts to the starting position and the carriage (12) remains in the raised rest position until the next change operation. The transport device (5) then conveys the taken-over reels (3) in any suitable manner to a collection point, further processing or the like.

Vorzugsweise-haben die Spulenwechseleinrichtung (1) mit den verschiedenen Hubdoffern (4), die Transporteinrichtung (5) und die Spuleinrichtung (2) mit den Überschiebeeinrichtungen (17) eine gemeinsame Steuerung (27), die in Figur 3 schematisch dargestellt ist. An dieser Steuerung (27) laufen die Bereitstellungssignale der Spuleneinrichtungen (2) für die fertigbewickelten Spulen (3) ein, woraufhin die Steuerung (27) den zugehörigen Hubdoffer (4) und seinen Spulenwechsler (15) in Gang setzt. Von der Steuerung (27) werden zur gegebenen Zeit dann auch die Überschiebeeinrichtungen (17) an den Windern (2) gesteuert und betätigt. Über die Steuerung (27) wird für den Spulenwechsel dann auch ein Transportwagen (22) angefordert und bereit gestellt. Die Spulenübergabe an die Transporteinrichtung (5) kann dabei aber auch etwas zeitverzögert ablaufen.Preferably, the bobbin changing device (1) with the various Hubdoffern (4), the transport device (5) and the winding device (2) with the Sliding devices (17) a common control (27), which is shown schematically in Figure 3. At this controller (27), the supply signals of the coil means (2) for the finished-wound coils (3) come in, whereupon the controller (27) sets the associated Hubdoffer (4) and its bobbin changer (15) in motion. From the controller (27) and the sliding devices (17) on the winders (2) are then controlled and operated at the given time. By means of the controller (27), a trolley (22) is then also requested and made available for the bobbin change. The bobbin transfer to the transport device (5) can also take place somewhat delayed.

Die Spulenwechseleinrichtung (1) kann eine Sicherungsvorrichtung (6) besitzen. Diese besteht in der gezeigten Ausführungsform beispielsweise aus mehreren stationären Abgrenzungen (25), z.B. Zäunen, die die Spuleinrichtungen (2) zumindest an ihren vorderen Zugangsbereichen (9) seitlich umgeben und gegeneinander abschirmen. Die Zäune (25) ragen dabei auch bis über die Hubdoffer (4) hinaus und sind frontseitig jeweils mit einer Türe (26), vorzugsweise einer automatischen Schiebetüre, verbunden. Diese Schiebetüre (26) sperrt den Zugangsbereich (9) vor den Spuleinrichtungen (2) während des Spulen- und Hülsenwechsels und während der Zeit, in der sich der Schlitten (12) in der unteren Position vor den Spuldornen (7,8) befindet. Wenn der Schlitten (12) die angehobene Ruheposition einnimmt, gibt er ein entsprechendes Positionssignal an die Steuerung (27), die dann ihrerseits mit der Sicherheitsvorrichtung (6) verbunden ist und die Türe (26) automatisch öffnet. Ein Bediener kann dann an die frisch aufgesteckten leeren Hülsen (21) gelangen und ggf. von der Spuleinrichtung (2) erforderliche Bedienarbeiten durchführen, z.B. den neuen Faden an den leeren Hülsen (21) festklemmen. Der Bediener muss dann rechtzeitig vor dem nächsten Spulenwechsel den Zugangsbereich (9) wieder verlassen, was ihm in geeigneter Weise von der Sicherheitsvorrichtung (6) signalisiert und nahegelegt wird. Die Türe (26) wird dann für den folgenden Spulenwechselvorgang wieder verschlossen.The bobbin changing device (1) may have a securing device (6). In the embodiment shown, this consists for example of a plurality of stationary delimitations (25), eg fences, which surround the winding devices (2) laterally at least at their front access areas (9) and shield them from one another. The fences (25) protrude beyond the Hubdoffer (4) and are front each with a door (26), preferably an automatic sliding door, connected. This sliding door (26) locks the access area (9) in front of the winding devices (2) during the bobbin and sleeve change and during the time in which the carriage (12) is in the lower position in front of the spool (7,8). When the carriage (12) assumes the raised rest position, it gives a corresponding position signal to the controller (27), which in turn is connected to the safety device (6) and automatically opens the door (26). An operator can then get to the freshly plugged empty sleeves (21) and possibly perform necessary by the winding device (2) operating, for example, clamp the new thread to the empty tubes (21). The operator must then in time before the next bobbin change the Leave access area (9) again, which is suitably signaled and suggested by the security device (6). The door (26) is then closed again for the following bobbin changing operation.

Abwandlungen der gezeigten Ausführungsform sind in verschiedener Weise möglich. Zum einen kann der Hubdoffer (4) auch eine anders ausgebildete und ausgerichtete Hubführung (10) aufweisen. Hierbei sind auch Schwenkführungen oder dergleichen möglich. Variabel ist ferner auch die Ausbildung und Anordnung der verschiedenen Komponenten des Spulenwechslers (15) und insbesondere der Einrichtungen (16,17,18). Der automatische Hülsenwechsler (19) mit dem Hülsenmagazin (20) kann ebenfalls variiert werden. Variabel ist ferner die Transporteinrichtung (5), die in beliebig anderer geeigneter Weise als Hängebahn oder dergleichen ausgebildet sein kann. In der bevorzugten Ausführungsform ist sie oberhalb des Zugangsbereichs (9) angeordnet. Die Sicherheitsvorrichtung (6) kann ebenfalls in ihrer Ausgestaltung und Anordnung abgewandelt werden. Sie kann auch ersatzlos entfallen oder nur in Teilen ausgeführt sein. Die gemeinsame Steuerung (27) lässt sich ebenfalls anders ausbilden und anordnen. Sie kann einerseits in eine Anlage übergreifende zentrale Prozesssteuerung integriert sein. Andererseits kann auch jedem Hubdoffer (4) eine eigene Steuerung zugeordnet sein, die ihrerseits mit einer zentralen Prozesssteuerung oder dergleichen verbunden ist, um die Bereitstellungssignale für die bewickelten Spulen (3) und den Spulenwechsel zu erhalten. Desgleichen kann auch die Transporteinrichtung (5) und die Sicherungsvorrichtung (6) eigenständig gesteuert und in entsprechend geeigneter Weise mit anderen Steuerungen verbunden bzw. in eine Steuerabfolge eingebunden sein.Modifications of the embodiment shown are possible in various ways. On the one hand, the Hubdoffer (4) also have a differently designed and aligned lifting guide (10). Here, pivoting guides or the like are possible. Also variable is the design and arrangement of the various components of the bobbin changer (15) and in particular of the devices (16, 17, 18). The automatic sleeve changer (19) with the sleeve magazine (20) can also be varied. Also variable is the transport device (5), which can be designed in any other suitable manner as a monorail or the like. In the preferred embodiment, it is located above the access area (9). The safety device (6) can also be modified in its design and arrangement. It can also be omitted without replacement or be executed only in parts. The common control (27) can also be formed and arranged differently. On the one hand, it can be integrated in a system-wide central process control. On the other hand, each Hubdoffer (4) may be assigned its own controller, which in turn is connected to a central process control or the like to the supply signals for the wound coils (3) and the bobbin change. Likewise, the transport device (5) and the securing device (6) can be independently controlled and connected in a suitably appropriate manner with other controllers or incorporated into a control sequence.
