Description

Die Erfindung betrifft eine Vorrichtung zur Speicherung und Bereitstellung von Spulhülsen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for storing and providing winding tubes according to the preamble of claim 1.

Bei der Herstellung und Behandlung von synthetischen Fäden ist es üblich, dass die Fäden am Ende eines Prozesses oder eines Teilprozesses zu Spulen aufgewickelt werden. Die Fäden werden hierzu am Umfang von Spulhülsen gewickelt, die durch einen Spulenhalter gehalten werden. Hierbei lässt sich die Spulhülse direkt durch den Spulhalter oder durch eine dem Spulhalter zugeordnete Treibwalze zum Aufwickeln des Fadens antreiben. Nach Fertigstellung der Spule ist es dabei üblich, an dem Spulenhalter einen Spulenwechsel auszuführen. Dies erfordert einen hohen manuellen Arbeitsaufwand, bei welchem zunächst die vollen Spulen von der Spulstelle entfernt werden und anschließend eine neue leere Spulhülse dem Spulhalter zugeführt wird. Um den manuellen Arbeitsaufwand möglichst zu minimieren, sind Vorrichtungen bekannt, die zumindest die Zuführung der leeren Spulhülsen im Wesentlichen automatisiert ausführen.In the manufacture and treatment of synthetic threads, it is common for the threads to be wound into spools at the end of a process or sub-process. For this purpose, the threads are wound on the periphery of winding tubes, which are held by a coil holder. In this case, the winding tube can be driven directly by the winding holder or by a drive roller associated with the winding holder for winding up the thread. After completion of the coil, it is customary to perform a bobbin change on the bobbin holder. This requires a high manual labor, in which initially the full bobbins are removed from the winding unit and then a new empty winding tube is fed to the bobbin holder. In order to minimize the manual work as possible, devices are known which perform at least the supply of empty bobbins substantially automated.

Eine derartige Vorrichtung ist beispielsweise aus der WO 2007/101649 A1 bekannt. Die bekannte Vorrichtung weist zur Speicherung einer größeren Anzahl von Spulhülsen einen Speicherschacht auf, in welchem die Spulhülsen als ein Hülsenstapel gehalten sind. Am Ende des Speicherschachtes ist eine Auslassöffnung vorgesehen, an welchem ein vertikal ausgerichtetes Führungsrohr angrenzt. Über ein auf den Hülsenstapel einwirkendes Dosiermittel wird eine selektive Abgabe der Spulhülse aus dem Speicherschacht über die Auslassöffnung und dem Führungsrohr gesteuert. Zur Aufnahme der herausgleitenden Spulhülsen ist dem freien Ende des Führungsrohres ein Aufnahmedorn zugeordnet, welcher die Spulhülse übernimmt. Der Aufnahmedorn ist verschwenkbar ausgebildet und lässt sich nach Übernahme der Spulhülse zu einer Spulstelle eine Aufwickeleinrichtung führen.Such a device is for example from the WO 2007/101649 A1 known. The known device has to store a larger number of bobbins on a storage slot in which the bobbins are held as a sleeve stack. At the end of the storage well an outlet opening is provided, on which a vertically aligned guide tube is adjacent. A selective dispensing of the winding tube from the storage shaft via the outlet opening and the guide tube is controlled via a dosing means acting on the tube stack. For receiving the sliding out of the winding tubes, a receiving mandrel is assigned to the free end of the guide tube, which takes over the winding tube. The receiving mandrel is designed to be pivotable and, after taking over the winding tube, can lead to a winding station a winding device.

Bei der bekannten Vorrichtung wird zur Abgabe einer Spulhülse der gesamte Hülsenstapel innerhalb des Speicherschachtes entlang dem Boden zur Auslassöffnung verschoben. Die im Boden des Speicherschachtes ausgebildete Auslassöffnung führt dazu, dass bei zunehmender Versschiebung des Hülsenstapels die Gefahr besteht, dass eine letzte Spulhülse innerhalb des Spulschachtes kippt und sich im Speicherschacht verkantet. Zudem lässt sich der Speicherschacht während des Betriebes nicht nachfüllen.In the known device, the entire sleeve stack is displaced within the storage shaft along the bottom to the outlet opening for dispensing a winding tube. The outlet opening formed in the bottom of the storage shaft means that, as the sleeve stack is pushed further, there is the risk that a last winding tube tilts inside the winding shaft and jams in the storage shaft. In addition, the memory slot can not be refilled during operation.

Es ist somit Aufgabe der Erfindung, die gattungsgemäße Vorrichtung zur Speicherung und Bereitstellung von Spulhülsen derart zu verbessern, dass eine selektive Führung und Abgabe der Spulhülsen sicher ausführbar ist.It is therefore an object of the invention to improve the generic device for storing and providing winding tubes in such a way that a selective guidance and delivery of the winding tubes is safely executable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Speicherschacht mit dem Hülsenstapel vertikal ausgerichtet ist und dass der Auslassöffnung außerhalb des Speicherschachtes einer Hülsenrutsche zugeordnet ist, die gegenüber einer Vertikalen eine Neigung und ein freies Ende aufweist, und dass das freie Ende des Aufnahmedorns in der Übernahme position unmittelbar dem freien Ende der Hülsenrutsche zugeordnet ist.This object is achieved in that the storage slot is aligned vertically with the sleeve stack and that the outlet opening outside the storage slot is associated with a tube slide having a slope relative to a vertical and a free end, and that the free end of the receiving mandrel in the assumption position is assigned directly to the free end of the tube slide.

Die Erfindung war auch nicht durch die bekannte Vorrichtung aus der JP 51-011938 naheliegend, bei welcher eine Mehrzahl von Spulhülsen in einem vertikal ausgerichteten Speicherschacht übereinander gehalten sind. Am Ende des Speicherschachtes ist eine Auslassöffnung ausgebildet, die zur Abgabe einer Speicherhülse mit einem Dosiermittel zusammenwirkt. Unterhalb der Auslassöffnung ist im Abstand zum Speicherschacht eine Fangschale angeordnet, die über einen Aktor horizontal verschiebbar gehalten ist. Der Fangteller lässt sich durch den Aktor zwischen einer Fangstellung und einer Übergabestellung hin- und herführen. In der Übergabestellung wird eine aus dem Speicherschacht abgegebene Spulhülse zu einem Greifarm geführt, welcher Greifarm die Spulhülse einer Spulstelle einer Aufwickeleinrichtung zuführt. Die bekannte Vorrichtung erfordert einen großen apparativen Aufwand, um eine aus dem Speicherschacht abgegebene Spulhülse zu einer Spulstelle zu befördern. Aufgrund der Vielzahl der Übergabestellen zur Beförderung der Spulhülse ist eine größere Störanfälligkeit der bekannten Vorrichtung zu erwarten.The invention was not by the known device from the JP 51-011938 Obviously, in which a plurality of winding tubes are held one above the other in a vertically aligned storage slot. At the end of the storage well, an outlet opening is formed which cooperates with a dosing means for dispensing a storage sleeve. Below the outlet opening a catch tray is arranged at a distance from the storage shaft, which is held horizontally displaceable via an actuator. The catcher can be guided back and forth by the actuator between a catch position and a transfer position. In the transfer position, a dispensed from the storage slot winding tube is guided to a gripping arm, which gripping arm feeds the winding tube of a winding unit of a take-up device. The known device requires a large amount of equipment in order to convey a dispensed from the storage slot winding tube to a winding unit. Due to the multitude of Transfer points for conveying the winding tube is expected to be more susceptible to interference of the known device.

Die Erfindung ermöglicht dagegen eine sichere Entnahme und Übergabe der Spulhülsen aus dem Speicherschacht ohne zusätzliche Zwischenübergaben. Die Spulhülsen werden dabei nach Freigabe durch ein Dosiermittel selbsttätig aus der Auslassöffnung und eine Hülsenrutsche auf das freie Ende des Aufnahmedorns geführt. Die geneigte Hülsenrutsche ermöglicht ein Ausrichten und Positionieren der Spulhülse, so dass die Spulhülse am Ende Hülsenrutsche direkt auf den Aufnahmedorn gleiten kann.By contrast, the invention makes it possible to securely remove and transfer the winding tubes from the storage shaft without additional intermediate transfers. The winding tubes are guided after release by a dosing automatically from the outlet opening and a tube slide on the free end of the mandrel. The inclined sleeve slide allows alignment and positioning of the winding tube, so that the winding tube at the end sleeve slide can slide directly onto the mandrel.

Um ein einwandfreies Abgleiten der Spulhülse an der Hülsenrutsche zu ermöglichen, weist die Hülsenrutsche eine Neigung gegenüber der Vertikalen mit einem Winkel im Bereich von 10° bis 75° auf.In order to allow a proper sliding of the winding tube on the tube slide, the tube slide has an inclination relative to the vertical at an angle in the range of 10 ° to 75 °.

Für die selektive Entnahme der Spulhülsen aus dem Speicherschacht ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher das Dosiermittel durch zwei im Abstand untereinander angeordnete Sperrriegel gebildet ist. Hierbei lassen sich die Sperrriegel durch separate Aktoren innerhalb des Speicherschachtes zwischen einer Sperrposition zum Blockieren der Spulhülsen und einer Freigabeposition zum Lösen der Spulhülsen führen. Damit ist eine selektive Entnahme einer oder mehrerer Spulhülsen aus dem Speicherschacht möglich. Hierbei dient der obere Sperrriegel zur Fixierung des Hülsenstapels innerhalb des Speicherschachtes. Der untere Sperrriegel lässt sich zur dosierten Abgabe der Spulhülsen betätigen.For the selective removal of the winding tubes from the storage shaft, the development of the invention is particularly advantageous, in which the dosing is formed by two spaced apart locking bolt. In this case, the locking bolt can be guided by separate actuators within the storage shaft between a locking position for blocking the winding tubes and a release position for releasing the winding tubes. For a selective removal of one or more winding tubes from the memory slot is possible. Here, the upper locking bar is used to fix the sleeve stack within the memory slot. The lower locking bolt can be actuated for the metered delivery of the winding tubes.

Um insbesondere jeweils eine letzte Spulhülse des Hülsenstapels aus dem Speicherschacht freigeben zu können, ist die Weiterbildung der Erfindung bevorzugt ausgeführt, bei welcher der Abstand zwischen dem oberen Sperrriegel und dem unteren Sperrriegel innerhalb des Speicherschachtes im wesentlichen gleich dem Durchmesser der Spulhülse ist und bei welcher die Aktoren durch eine Steuereinrichtung wechselweise aktivierbar sind. Damit lässt sich der Hülsenstapel innerhalb des Speicherschachtes während der Abgabe der letzten Spulhülse fixiert halten. Erst nachdem die letzte Spulhülse aus dem Speicherschacht geführt ist, erfolgt eine Nachführung des Hülsenstapels.In particular, to be able to release a last winding tube of the sleeve stack from the memory slot, the development of the invention is preferably carried out in which the distance between the upper locking bolt and the lower locking bolt within the memory slot is substantially equal to the diameter of the winding tube and in which the Actuators are alternately activated by a control device. This allows the core stack within Keep the storage bay fixed during the delivery of the last winding tube. Only after the last winding tube is guided out of the storage shaft, a tracking of the sleeve stack is done.

Die Entnahme einer der Spulhülsen aus dem Speicherschacht erfolgt vorzugsweise mit einem Kontaktsensor, welcher eine Lage des Aufnahmedorns auf der Auslassseite des Speicherschachtes erfasst. Somit lässt sich bei Erreichen des Aufnahmedorns in eine Übernahmeposition das Dosiermittel über die Steuereinrichtung aktivieren, so dass die Entnahmen von Spulhülsen nur in dem Fall erfolgen, in dem der Aufnahmedorn seine Übernahmeposition einhält.The removal of one of the winding tubes from the storage shaft is preferably carried out with a contact sensor which detects a position of the receiving mandrel on the outlet side of the storage slot. Thus, when the mandrel is reached into a take-over position, the dosing agent can be activated via the control device, so that the withdrawals of winding tubes take place only in the case in which the receiving mandrel complies with its takeover position.

Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist die Auslassöffnung am Ende des Speicherschachtes durch einen rechteckigen Öffnungsquerschnitt gebildet, dessen Öffnungslänge kürzer ist als eine Hülsenlänge der Spulhülse und dessen Öffnungsbreite größer ist als ein Durchmesser der Spulhülse. Damit lässt sich beim Austreten der Spulhülse aus dem Speicherschacht bereits an der Spulhülse eine Vorneigung erzeugen, die zu einem sanften Übergleiten in die Hülsenrutsche ermöglicht. Die Öffnungslänge des Öffnungsquerschnittes der Auslassöffnung bestimmt dabei im Wesentlichen den Neigungswinkel der Spulhülse bei Austreten aus dem Speicherschacht.In a particularly advantageous embodiment of the invention, the outlet opening is formed at the end of the storage slot by a rectangular opening cross-section whose opening length is shorter than a sleeve length of the winding tube and the opening width is greater than a diameter of the winding tube. Thus, when the winding tube emerges from the storage shaft, a pre-tilt can already be produced on the winding tube, which allows a gentle sliding over into the tube chute. The opening length of the opening cross-section of the outlet opening essentially determines the angle of inclination of the winding tube when it leaves the storage shaft.

Um an der Auslassöffnung ein selbsttätiges Ausgleiten der Spulhülse im geneigten Zustand zu erreichen, ist die Öffnungslänge des Öffnungsquerschnittes der Auslassöffnung länger als die halbe Hülsenlänge der Spulhülse. Damit wird allein durch die Schwerkraft der Spulhülse an der Spulhülse ein Kippmoment erzeugt.In order to achieve an automatic slipping of the winding tube in the inclined state at the outlet opening, the opening length of the opening cross-section of the outlet opening is longer than half the sleeve length of the winding tube. Thus, a tilting moment is generated solely by the gravity of the winding tube on the winding tube.

Ein derartiges Kippmoment lässt sich an der Spulhülse jedoch auch durch einen unteren Sperrriegel erzeugen, der durch zwei Kolbenstangen separat ansteuerbarer Kolben-Zylinder-Einheiten gebildet ist.However, such a tilting moment can be produced at the winding tube by a lower locking bolt, which is formed by two piston rods separately controllable piston-cylinder units.

Das Nachfüllen des Speicherschachtes mit Spulhülsen erfolgt über die Einlassöffnung am oberen Ende des Speicherschachtes. Hierbei können die Spulhülsen manuell oder automatisiert zugeführt werden.The refilling of the storage slot with winding tubes takes place via the inlet opening at the upper end of the storage slot. Here, the winding tubes can be fed manually or automatically.

Um den Füllungsgrad innerhalb des Speicherschachtes zu überwachen, ist gemäß einer vorteilhaften Weiterbildung der Erfindung zumindest an einer Seitenwand des Speicherschachtes eine Sichtöffnung ausgebildet. Alternativ besteht jedoch auch die Möglichkeit einen Überwachungssensor in dem Speicherschacht anzuordnen, der beispielsweise mit einer Signaleinrichtung verbunden ist und im Fall einer Nachfüllung das Signalmittel aktiviert.In order to monitor the degree of filling within the storage shaft, according to an advantageous development of the invention, at least on one side wall of the storage shaft, a viewing opening is formed. Alternatively, however, it is also possible to arrange a monitoring sensor in the memory slot, which is connected, for example, to a signal device and activates the signal means in the event of refilling.

In den Fig. 1 und 2 ist ein erstes Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zur Speicherung und Bereitstellung von Spulhülsen in mehreren Ansichten gezeigt. In Fig. 1 ist das Ausführungsbeispiel in einer Seitenansicht unmittelbar neben einer Aufwickeleinrichtung dargestellt. Die Fig. 2 stellt das Ausführungsbeispiel in einer Teilansicht eines Querschnittes dar. Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.In the Fig. 1 and 2 a first embodiment of the inventive device for storing and providing winding tubes is shown in several views. In Fig. 1 the embodiment is shown in a side view immediately adjacent to a winding device. The Fig. 2 shows the embodiment in a partial view of a cross section. Unless expressly made to one of the figures, the following description applies to both figures.

Das Ausführungsbeispiel der erfindungsgemäßen Vorrichtung weist einen vertikal ausgerichteten Speicherschacht 1 auf, der quaderförmig zur Aufnahme mehrerer übereinander liegender Spulhülsen 18 ausgebildet ist. Die Spulhülsen 18 sind innerhalb des Speicherschachtes 1 horizontal ausgerichtet und bilden einen Hülsenstapel 19.The embodiment of the device according to the invention has a vertically aligned storage slot 1, which is formed in a cuboid for receiving a plurality of superimposed winding tubes 18. The winding tubes 18 are horizontally aligned within the storage slot 1 and form a sleeve stack 19th

Der Speicherschacht 1 weist am oberen Ende eine Einlegöffnung 2 und am Boden 6 eine Auslassöffnung 3 auf. In einer der Seitenwandungen 5.1 des Speicherschachtes 1 ist eine Sichtöffnung 7 ausgebildet. An der gegenüber liegenden Seitenwand 5.2 ist im unteren Bereich ein Dosiermittel 4 angeordnet, das in diesem Ausführungsbeispiel durch einen oberen Sperrriegel 9 und einen unteren Sperrriegel 10 gebildet sind. Der obere Sperrriegel 9 und der untere Sperrriegel 10 sind jeweils mit einem Aktor 11.1 und 11.2 gekoppelt, durch welchen die Sperrriegel 9 und 10 im Innern des Speicherschachtes 1 zwischen einer Sperrposition zum Blockieren der Spulhülsen und einer Freigabeposition zum Lösen der Spulhülsen führbar sind. In den Fig. 1 und 2 befinden sich die Sperrriegel 9 und 10 jeweils in ihrer Sperrposition, so dass die Spulhülsen 18 bzw. der Hülsenstapel 19 innerhalb des Speicherschachtes 1 fixiert gehalten sind.The storage shaft 1 has an insertion opening 2 at the upper end and an outlet opening 3 at the bottom 6. In one of the side walls 5.1 of the storage slot 1, a viewing port 7 is formed. At the opposite side wall 5.2 a metering means 4 is arranged in the lower region, which are formed in this embodiment by an upper locking bolt 9 and a lower locking bolt 10. The upper locking bolt 9 and the lower locking bolt 10 are each coupled to an actuator 11.1 and 11.2, through which the locking bars 9 and 10 in the interior of the memory slot 1 between a locking position for blocking the winding tubes and a release position for releasing the winding tubes are feasible. In the Fig. 1 and 2 The locking bars 9 and 10 are each in their locking position, so that the winding tubes 18 and the sleeve stack 19 are kept fixed within the storage slot 1.

Wie aus der Fig. 2 zu entnehmen ist, ist zwischen den Sperrriegel 9 und 10 jeweils ein Abstand gebildet ist, der im Wesentlichen gleich dem Durchmesser der Spulhülse 18 ist.Like from the Fig. 2 can be seen, between the locking bolt 9 and 10 each have a distance is formed, which is substantially equal to the diameter of the winding tube 18.

Der untere Sperrriegel 10 ist innerhalb des Speicherschachtes 1 unmittelbar der Auslassöffnung 3 vorgeordnet.The lower locking bolt 10 is disposed directly upstream of the outlet opening 3 within the storage shaft 1.

Wie aus den Fig. 1 und 2 hervorgeht, ist der Auslassöffnung 3 außerhalb des Speicherschachtes 1 eine Hülsenrutsche 8 zugeordnet. Die Hülsenrutsche 8 ist mit einer Neigung gegenüber einer Vertikalen nach unten gerichtet.Like from the Fig. 1 and 2 it can be seen, the outlet opening 3 outside the storage shaft 1 is associated with a sleeve slide 8. The sleeve chute 8 is directed downwards with an inclination to a vertical.

Unterhalb der Hülsenrutsche 8 ist an einem Träger 17 ein beweglicher Aufnahmedorn 14 angeordnet. Der Aufnahmedorn 14 wird über eine Schwenkachse 16 schwenkbar an dem Träger 17 gehalten.Below the tube chute 8, a movable receiving mandrel 14 is arranged on a carrier 17. The receiving mandrel 14 is held pivotably on the carrier 17 via a pivot axis 16.

Wie aus der Fig. 1 hervorgeht, lässt sich der Aufnahmedorn 14 zwischen einer Übernahmeposition und einer Abgabeposition verschwenken. In Fig. 1 ist der Aufnahmedorn 14 in einer Übernahmeposition gezeigt, wobei das freie Ende des Aufnahmedorns 14 unmittelbar dem freien Ende der Hülsenrutsche 8 zugeordnet ist.Like from the Fig. 1 As can be seen, the receiving mandrel 14 can be pivoted between a transfer position and a delivery position. In Fig. 1 the receiving mandrel 14 is shown in a transfer position, wherein the free end of the receiving mandrel 14 is assigned directly to the free end of the tube slide 8.

Die Abgabeposition des Aufnahmedorns 14 ist in Fig. 1 gestrichelt dargestellt. Hierbei steht der Aufnahmedorn 14 unmittelbar einer Spulstelle 21 einer Aufwickeleinrichtung 20 gegenüber. In dieser Stellung des Aufnahmedorns lassen sich die am Umfang gehaltenen Spulhülsen 18 durch ein dem Aufnahmedorn 14 zugeordnetes Abschiebemittel 15 abstreifen und der Spulstelle 21 zuführen. Das Abschiebemittel 15 ist in diesem Ausführungsbeispiel durch einen Schubring gebildet, welcher am Umfang des Aufnahmedorns 14 hin- und herführbar ist.The dispensing position of the receiving mandrel 14 is in Fig. 1 shown in dashed lines. Here, the receiving mandrel 14 is directly opposite a winding unit 21 of a winding device 20. In this position of the mandrel, the winding tubes 18 held on the circumference can be stripped off by a removal means 15 assigned to the receiving mandrel 14 and fed to the winding station 21. The Abschiebemittel 15 is formed in this embodiment by a thrust ring, which is on the periphery of the mandrel 14 back and forth.

In diesem Ausführungsbeispiel ist die Spulstelle 21 der Aufwickeleinrichtung 20 durch zwei Spulspindeln 22.1 und 22.2 gebildet, die an einem Drehteller 23 gehalten sind und abwechselnd zwischen einer Betriebsposition und einer Wechselposition führbar sind. Jede der Spulspindeln 22.1 und 22.2 ist über einen Elektromotor antreibbar. In der Betriebsposition wirken die Spulspindeln 22.1 und 22.2 abwechselnd mit einer Andrückwalze 24 und einer Changiereinrichtung 25 zusammen, um jeweils zwei Fäden 26 parallel auf zwei Spulhülsen zu Spulen zu wickeln. Die Spulhülsen 18 werden dabei zuvor in der Wechselposition der Spulspindeln 22.1 und 22.2 durch den Aufnahmedorn 14 bereitgestellt und auf die jeweils leere Spulspindel aufgeschoben.In this embodiment, the winding unit 21 of the winding device 20 is formed by two winding spindles 22.1 and 22.2, which are held on a turntable 23 and can be guided alternately between an operating position and a change position. Each of the winding spindles 22.1 and 22.2 can be driven by an electric motor. In the operating position, the winding spindles 22.1 and 22.2 interact alternately with a pressure roller 24 and a traversing device 25 in order to wind two threads 26 in parallel on two winding tubes to form coils. The winding tubes 18 are previously provided in the change position of the winding spindles 22.1 and 22.2 through the receiving mandrel 14 and pushed onto the respective empty winding spindle.

Die Aufwickeleinrichtung ist in diesem Ausführungsbeispiel beispielhaft. So können die Spulspindeln auch durch andersartige Spulenhalter ersetzt werden, die beispielsweise nur eine Spulhülse zum Aufwickeln eines Fadens halten.The winding device is exemplary in this embodiment. Thus, the winding spindles can also be replaced by different types of bobbin holders, which, for example, hold only one bobbin tube for winding a thread.

Zur weiteren Erläuterung der erfindungsgemäßen Vorrichtung wird nun Bezug zu der Fig. 2 genommen.For further explanation of the device according to the invention will now be related to the Fig. 2 taken.

Am freien Ende der Hülsenrutsche 8 ist ein Nährungssensor 13 angeordnet, welcher das freie Ende des Aufnahmedorns 14 sensiert. So lässt sich das Erreichen der Übernahmeposition des Aufnahmedorns 14 durch den Nährungssensor 13 erfassen. Der Nährungssensor 13 ist mit einer Steuereinrichtung 12 gekoppelt, die die Aktivierung der Aktoren 11.1 und 11.2 steuert.At the free end of the tube slide 8, a proximity sensor 13 is arranged, which senses the free end of the receiving mandrel 14. Thus, reaching the take-over position of the receiving mandrel 14 by the proximity sensor 13 can be detected. The proximity sensor 13 is coupled to a control device 12, which controls the activation of the actuators 11.1 and 11.2.

Für den Fall, dass der Aufnahmedorn 14 seine Übernahmeposition am freien Ende der Hülsenrutsche 8 erreicht hat, wird die Lage des Aufnahmedorns 14 durch den Nährungssensor 13 erfasst und eine entsprechende Signalgebung erfolgt zur Steuereinrichtung 12. Die Steuereinrichtung 12 bewirkt nun eine Aktivierung des Aktors 11.2, um den unteren Sperrriegel 10 aus seiner Sperrposition in eine Freigabeposition zu führen. Die letzte Spulhülse 18 des Hülsenstapels 19 wird freigegeben und fällt selbsttätig auf den Boden 6 des Speicherschachtes 1. Eine derartige Situation ist in der Fig. 3 schematisch dargestellt.In the event that the receiving mandrel 14 has reached its transfer position at the free end of the tube slide 8, the position of the receiving mandrel 14 is detected by the proximity sensor 13 and a corresponding signaling is carried out to the control device 12. The control device 12 now causes an activation of the actuator 11.2, to guide the lower locking bar 10 from its locking position to a release position. The last winding tube 18 of the sleeve stack 19 is released and falls automatically on the bottom 6 of the memory slot 1. Such a situation is in the Fig. 3 shown schematically.

In den Fig. 3 und 4 ist hierzu eine Teilansicht des Ausführungsbeispiels in einer Schnittdarstellung gezeigt. Die Fig. 3 und 4 stellen unterschiedliche Zustände bei der Abgabe einer der Spulhülsen dar. Wie aus den Fig. 3 und 4 hervorgeht, erstreckt sich die Auslassöffnung 3 im Boden 6 des Speicherschachtes 1 nur über eine Teillänge der Spulhülse 18. Dadurch wird erreicht, dass die Spulhülse 18 die Auslassöffnung 3 mit einer Neigung in Richtung der Hülsenrutsche 8 verlässt.In the Fig. 3 and 4 For this purpose, a partial view of the embodiment is shown in a sectional view. The Fig. 3 and 4 represent different states in the delivery of one of the Spulhülsen. As from the Fig. 3 and 4 As can be seen, the outlet opening 3 extends in the bottom 6 of the storage shaft 1 only over a partial length of the winding tube 18. This ensures that the winding tube 18 leaves the outlet opening 3 with an inclination in the direction of the tube slide 8.

Diese Situation ist in Fig. 4 dargestellt. Damit lässt sich die Spulhülse 18 sicher aus dem Inneren des Speicherschachtes 1 zur äußeren Hülsenrutsche 8 überführen. Die Hülsenrutsche 8 weist gegenüber einer Vertikalen einen Neigungswinkel α auf, der vorzugsweise im Bereich von 10° bis 75° ausgebildet ist. Mit dem Neigungsgrad der Hülsenrutsche 8 lässt sich dabei insbesondere die Führungsgeschwindigkeit der Spulhülse 18 und das Zuführen der Spulhülse 18 zu dem freien Ende des Aufnahmedorns 14 bestimmen.This situation is in Fig. 4 shown. Thus, the winding tube 18 can be safely transferred from the interior of the storage shaft 1 to the outer sleeve slide 8. The sleeve slide 8 has a tilt angle α relative to a vertical, which is preferably formed in the range of 10 ° to 75 °. In particular, the guide speed of the winding tube 18 and the feeding of the winding tube 18 to the free end of the receiving mandrel 14 can be determined by the degree of inclination of the tube chute 8.

Die im Boden 6 des Speicherschachtes 1 ausgebildete Auslassöffnung 3 weist bevorzugt einen rechteckigen Öffnungsquerschnitt auf. In Fig. 5 ist eine Draufsicht einer Auslassöffnung 3 im Boden 6 des Speicherschachtes 1 dargestellt. Der Öffnungsquerschnitt der Auslassöffnung 3 ist durch die Öffnungslänge L und die Öffnungsbreite B gekennzeichnet. Um bei Auftreffen der Spulhülse am Boden 6 des Speicherschachtes 1 einen Kippmoment an der Spulhülse 18 zu erzeugen, ist die Öffnungslänge L des Öffnungsquerschnittes bevorzugt länger ausgebildet als die halbe Länge der Spulhülse 18. Damit lässt sich allein durch die Schwerkraft ein Auskippen der Spulhülsen aus dem Speicherschacht 1 erreichen. Die Öffnungsbreite B ist dabei größer als der Durchmesser der Spulhülse 18 ausgebildet, so dass die Spulhülse ohne Widerstand aus dem Speicherschacht 1 heraustreten kann.The outlet opening 3 formed in the bottom 6 of the storage shaft 1 preferably has a rectangular opening cross-section. In Fig. 5 is a plan view of an outlet opening 3 in the bottom 6 of the memory slot 1 shown. The opening cross section of the outlet opening 3 is characterized by the opening length L and the opening width B. In order to produce a tilting moment on the winding tube 18 upon impact of the winding tube on the bottom 6 of the storage channel 1, the opening length L of the opening cross-section is preferably longer than half the length of the winding tube 18. Thus, a mere tilting of the winding tubes from the Reach memory slot 1. The opening width B is greater than the diameter of the winding tube 18 is formed so that the winding tube can emerge from the storage slot 1 without resistance.

Für die Führung der Spulhülsen innerhalb des Speicherschachtes 1 hat sich eine Gesamtbreite des Speicherschachtes als besonders vorteilhaft herausgestellt, die um 5% bis 10% größer als die Länge einer der Spulhülsen 18. Damit wird beim Nachrücken der Spulhülsen 18 bzw. des Hülsenstapels 19 ein Verkeilen der Spulhülsen durch Kippen vermieden.For the leadership of the winding tubes within the memory slot 1, a total width of the memory slot has been found to be particularly advantageous, which is greater by 5% to 10% than the length of the winding tubes 18. Thus, when moving the winding tubes 18 and the sleeve stack 19, a wedging the winding tubes avoided by tilting.

Während die Spulhülse 18 über die Hülsenrutsche 8 an den Aufnahmedorn 14 übergeben wird, wird der untere Sperrriegel 10 durch Aktivierung des Aktors 11.2 aus seiner Freigabeposition in die Sperrposition zurückgeführt. Kurz danach oder zeitgleich wird der Aktor 11.1 des oberen Sperrriegels 9 aktiviert, um den oberen Sperrriegel 9 aus der Sperrposition in eine Freigabeposition zu führen. Nun ist der gesamte Hülsenstapel 19 innerhalb des Speicherschachtes 1 freigegeben, so dass sich der Hülsenstapel 19 innerhalb des Speicherschachtes bis zum unteren Sperrriegel 10 verschiebt, wie aus Fig. 2 hervorgeht.While the winding tube 18 is transferred via the sleeve slide 8 to the receiving mandrel 14, the lower locking bolt 10 is returned by activation of the actuator 11.2 from its release position to the locked position. Shortly afterwards or at the same time, the actuator 11.1 of the upper locking bolt 9 is activated to guide the upper locking bolt 9 from the locking position to a release position. Now that is entire sleeve stack 19 released within the memory slot 1, so that the sleeve stack 19 shifts within the memory slot to the lower locking bar 10, as from Fig. 2 evident.

Bevor nun eine zweite Spulhülse aus dem Speicherschacht 1 entnommen wird, wird zunächst der Aktor 11.1 aktiviert, um den oberen Sperrriegel 9 aus seiner Freigabeposition in die in Fig. 2 gezeigte Sperrposition zu führen. Nun kann der gesamte Vorgang zu Freigabe der letzten Spulhülse von neuem beginnen.Before now a second winding tube is removed from the storage slot 1, the actuator 11.1 is first activated to the upper locking bar 9 from its release position in the in Fig. 2 to show the locked position shown. Now the whole process to release the last winding tube can start anew.

Zur Überwachung der Aufnahme der Spulhülsen an dem Aufnahmedorn 14 besteht ebenfalls die Möglichkeit, dass an dem Aufnahmedorn 14 Kontaktsensoren angeordnet sind, die beispielsweise einen Schwenkaktor zum Verschwenken des Aufnahmedorns 14 aktivieren.To monitor the recording of the winding tubes on the receiving mandrel 14, there is also the possibility that 14 contact sensors are arranged on the receiving mandrel, for example, activate a pivoting actuator for pivoting the mandrel 14.

Bei der in Fig. 2 dargestellten Situation besteht auch die Möglichkeit, die Sperrriegel 9 und 10 derart auszubilden, dass der Hülsenstapel 19 bis zur untersten Spulhülse 18 reicht. In diesem Fall ragt der Sperrriegel 9 nur so weit in den Speicherschacht 1 hinein, dass ein Kontakt zwischen der letzten und vorletzten Spulhülse 18 möglich ist. Vorzugsweise bleibt zwischen dem freien Ende des Sperrriegels 9 und der vorletzten Spulhülse 18 ein kleiner Spalt, so dass der gesamte Hülsenstapel 19 durch den unteren Sperrriegel 10 gehalten wird. Durch eine derartige Ausbildung wird die Abgabe der letzten Spulhülse nach Freigabe des Sperrriegels 10 vorteilhaft unterstützt. Der Hülsenstapel 19 kann jedoch nur bis zur Überbrückung des Spaltes zum Sperrriegel 9 nachrücken.At the in Fig. 2 illustrated situation, it is also possible, the locking bolt 9 and 10 in such a way that the sleeve stack 19 extends to the lowest winding tube 18. In this case, the locking bar 9 protrudes into the storage slot 1 only so far that contact between the last and penultimate winding tube 18 is possible. Preferably, a small gap remains between the free end of the locking bolt 9 and the penultimate winding sleeve 18, so that the entire sleeve stack 19 is held by the lower locking bolt 10. Such a design, the delivery of the last winding tube after release of the locking bolt 10 is advantageously supported. However, the sleeve stack 19 can only move up to bridging the gap to the locking bolt 9.

Bei dem in Fig. 1 und 2 dargestellten Ausführungsbeispiel der erfindungsgemäßen Vorrichtung sind die Sperrriegel 9 und 10 durch elektrische Aktoren 11.1 und 11.2 betätigt. Grundsätzlich lassen sich jedoch auch Pneumatikzylinder verwenden, um derartige Sperrriegel in zwei Positionen zu führen. In den Fig. 6 und 7 ist ein mögliches Ausführungsbeispiel eines Sperrriegels dargestellt. Die Fig. 6 zeigt dabei den Sperrriegel in einer Sperrposition und in Fig. 7 ist der Sperrriegel in einer Freigabeposition gezeigt. Es kann sich hierbei sowohl um den unteren Sperrriegel 10 als auch um den oberen Sperrriegel 9 halten. Grundsätzlich lassen sich beide Sperrriegel 9 und 10 in einer derartigen Ausführung ausgestalten. In diesem Beispiel sind zwei Kolben-Zylinder-Einheiten 28.1 und 28.2 nebeneinander an der Seitenwand 5.2 des Speicherschachtes 1 angeordnet. Die Kolbenstangen 27.1 und 27.2 sind innerhalb der Kolben-Zylinder-Einheiten 28.1 und 28.2 jeweils durch Federn 29.1 und 29.2 derart belastet, dass die freien Enden der Kolbenstangen 27.1 und 27.2 innerhalb des Speicherschachtes 1 in einer Sperrposition gehalten sind. Diese Situation ist in Fig. 6 gezeigt.At the in Fig. 1 and 2 illustrated embodiment of the device according to the invention, the locking bolt 9 and 10 are actuated by electric actuators 11.1 and 11.2. In principle, however, pneumatic cylinders can also be used to guide such locking bars in two positions. In the 6 and 7 is a possible embodiment of a locking bar shown. The Fig. 6 shows the locking bolt in a locked position and in Fig. 7 the locking bar is shown in a release position. This can be both the lower locking bolt 10 and hold around the upper locking bar 9. In principle, both locking bars 9 and 10 can be configured in such an embodiment. In this example, two piston-cylinder units 28.1 and 28.2 are arranged side by side on the side wall 5.2 of the storage shaft 1. The piston rods 27.1 and 27.2 are loaded within the piston-cylinder units 28.1 and 28.2 in each case by springs 29.1 and 29.2 such that the free ends of the piston rods 27.1 and 27.2 are held within the storage shaft 1 in a locking position. This situation is in Fig. 6 shown.

Um eine letzte Spulhülse 18 oder den Hülsenstapel 19 innerhalb des Speicherschachtes 1 zu lösen, werden die Kolben-Zylinder-Einheiten 28.1 und 28.2 gemeinsam angesteuert, so dass die Kolbenstangen 27.1 und 27.2 gegen die Federkraft der Federn 29.1 und 29.2 zurückgeführt werden und ihre Freigabeposition einnehmen. Diese Situation ist in Fig. 7 dargestellt.In order to solve a last winding tube 18 or the sleeve stack 19 within the storage shaft 1, the piston-cylinder units 28.1 and 28.2 are jointly controlled so that the piston rods 27.1 and 27.2 are returned against the spring force of the springs 29.1 and 29.2 and occupy their release position , This situation is in Fig. 7 shown.

Bei einem unteren Sperrriegel 10 könnten die Kolben-Zylinder-Einheiten 28.1 und 28.2 auch kurz nacheinander betätigt werden, so dass die Spulhülse bereits in einer geneigten Stellung zum Boden 6 des Speicherschachtes 1 fällt.In a lower locking bolt 10, the piston-cylinder units 28.1 and 28.2 could also be actuated shortly after one another, so that the winding tube already falls in an inclined position to the bottom 6 of the storage shaft 1.

Die in Fig. 6 und 7 dargestellten Antriebe der Sperrriegel 9 und 10 können alternativ auch durch doppelwirkende Kolben-Zylinder-Einheiten gebildet werden.In the 6 and 7 shown drives the locking bolt 9 and 10 may alternatively be formed by double-acting piston-cylinder units.

Die erfindungsgemäße Vorrichtung zeichnet sich somit besonders dadurch aus, dass das Zuführen der Spulhülsen zu einer Spulstelle eine Aufwickeleinrichtung ohne manuelle Unterstützung erfolgen kann, um einen hohen Grad an Automatisierung zu erreichen. So werden vorzugsweise nur die Nachfüllarbeiten des Speicherschachtes manuell ausgeführt.The device according to the invention is thus characterized in particular by the fact that the feeding of the winding tubes to a winding station, a winding device can take place without manual assistance, in order to achieve a high degree of automation. Thus, preferably only the refilling of the memory slot are performed manually.
