Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Entfernen von Spulenhülsen von den Spulendornen eines Spulengatters od.dgl., mit einer Hülsentransporteinrichtung, die eine Vielzahl mit der Teilung der Spulendorne aufgereihter Transporteure hat, die mit einer motorischen Antriebseinrichtung zwischen Hülsenaufnahmestellungen und Hülsenabladestellungen verstellbar sind, und mit einer die Hülse von den Spulendornen entfernenden Hülsenübernahmeeinrichtung.The invention relates to a device for removing bobbin tubes from the bobbins of a creel or the like, with a bobbin transport device which has a large number of transporters lined up with the division of the bobbin bobbins, which can be adjusted with a motorized drive device between bobbin receiving positions and bobbin unloading positions, and with a sleeve take-over device that removes the sleeve from the spindles.

Aus der DE-A-37 02 379 ist eine Vorrichtung mit den eingangs genannten Merkmalen bekannt. Die bekannte Hülsentransporteinrichtung besitzt einen starren geraden Hülsentragarm, der die aufgereihten Transporteure aufweist. Dieser Hülsentragarm wird von der motorischen Antriebseinrichtung nach dem Eingreifen der Transporteure in die Hülsen aus einer vertikalen Stellung, in der sich die Transporteure in Hülsenaufnahmestellungen befinden, in eine horizontale Stellung bewegt, in der die Transporteure vertikal nach unten angeordnet sind. Der Hülsentragarm wird dann angehoben und vom Spulengatter bis oberhalb der Hülsenübernahmeeinrichtung entfernt. Dann erfolgt ein Absenken des Hülsentragarms, bis die Hülsen auf einem Hülsenhalter aufsitzen. Die Transporteure geben dann die leeren Hülsen frei und werden aus ihren Hülsenabladestellungen entfernt. Für die Bewegungen des Spulenarms zwischen den Hülsenaufnahmestellungen und den Hülsenabladestellungen der Transporteure dient ein senkrecht zum Gatter verfahrbares Gestell, an dem ein den Hülsentragarm tragender Gelenkarm befestigt ist. Dieser Gelenkarm vermag die vorbeschriebenen Bewegungen des vorgenannten Hülsentragarms zu steuern. Der Gelenkarm dient auch dazu, mit Spulen beladene Transporteure aus einer gesonderten Spulenaufnahmestellung in dem Spulengatter benachbarte Spulenübergabestellungen zu bewegen, wobei das Gatter mit Spulen bestückt wird, also mit vollbewickelten Hülsen.From DE-A-37 02 379 a device with the features mentioned above is known. The known sleeve transport device has a rigid, straight sleeve support arm, which has the lined-up conveyors. This sleeve support arm is moved by the motor drive device after the transporters have engaged in the sleeves from a vertical position in which the transporters are in the sleeve receiving positions to a horizontal position in which the transporters are arranged vertically downward. The sleeve support arm is then raised and removed from the creel to above the sleeve transfer device. Then the sleeve support arm is lowered until the sleeves are seated on a sleeve holder. The carriers then release the empty pods and become theirs Sleeve unloading positions removed. For the movements of the bobbin arm between the tube receiving positions and the tube unloading positions of the transporters, a frame which can be moved perpendicular to the gate and to which an articulated arm carrying the tube supporting arm is attached. This articulated arm can control the above-described movements of the aforementioned sleeve support arm. The articulated arm also serves to move transporters loaded with bobbins from a separate bobbin receiving position in the bobbin creel adjacent bobbin transfer positions, the creel being equipped with bobbins, that is to say with fully wound sleeves.

Die vorbeschriebene bekannte Hülsenentfernungsvorrichtung hat eine sehr aufwendige motorische Antriebseinrichtung für die Transporteure. Die bekannte Hülsentransporteinrichtung setzt außerdem voraus, daß die Hülsenübernahmeeinrichtung die Hülsen von dem Spulengatter mit der Teilung der Spulendorne übernehmen kann. Hierzu wird eine einen erheblichen baulichen Aufwand aufweisende Hülsenübernahmeeinrichtung verwendet, die unter anderem ein horizontal umlaufendes Förderband hat, also auch noch einen erheblichen Platzbedarf aufweist.The known sleeve removal device described above has a very complex motor drive device for the transporters. The known sleeve transport device also presupposes that the sleeve transfer device can take over the sleeves from the creel with the division of the coil mandrels. For this purpose, a sleeve transfer device is used, which has a considerable structural outlay and which, among other things, has a horizontally rotating conveyor belt, and therefore also requires a considerable amount of space.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung mit den eingangs genannten Merkmalen so zu verbessern, daß das automatische Entfernen der Hülsen von den Spulendornen eines Spulengatters mit einfachen Mitteln verschwenkungsfrei erfolgen kann.In contrast, the invention has for its object to improve a device with the features mentioned so that the automatic removal of the sleeves from the spindles of a creel can be done with simple means without pivoting.

Diese Aufgabe wird dadurch gelöst, daß die Hülsentransporteinrichtung einen in einer vertikalen Ebene umlaufenden flexiblen Endlosförderer für die als Transportdorne ausgebildeten Transporteure hat, daß die Hülsenübernahmeeinrichtung die Hülsen von den Spulendornen auf die Transportdorne zu verschieben vermag, und daß der Endlosförderer die mit Hülsen beladenen Transportdorne nacheinander in das Herunterrutschen der Hülsen von den Dornen durch Schwerkraft bewirkende Hülsenabladestellungen über einen Hülsensammelbehälter fördert.This object is achieved in that the sleeve transport device has a flexible endless conveyor that rotates in a vertical plane for the transporters designed as transport mandrels, that the sleeve transfer device is able to move the sleeves from the spools to the transport mandrels, and that the endless conveyor successively transports the loaded mandrels promotes in the sliding of the sleeves from the thorns by gravity-effecting sleeve unloading positions over a sleeve collecting container.

Für die Erfindung ist von Bedeutung, daß die Hülsentransporteinrichtungen einen umlaufenden Endlosförderer für die Transportdorne hat, die also auf einer in sich geschlossenen Bahn in einer einzigen Ebene umlaufen. Infolgedessen braucht die motorische Antriebseinrichtung nicht dafür ausgelegt zu sein, die Transportdorne in zueinander unterschiedlichen Ebenen auszurichten, weil die Hülsen in ihren Hülsenaufnahmestellungen und in ihren Hülsenabladestellungen entsprechend unterschiedlich anzuordnen wären. Es ergibt sich grundsätzlich eine erhebliche Vereinfachung der Antriebseinrichtung. Die Flexibilität des Endlosförderers gestattet es, seine Bahn grundsätzlich so zu gestalten, daß die Transportdorne in ihren Hülsenaufnahme- bzw. -abladestellungen die jeweils optimale Stellung einnehmen, ohne daß deswegen die motorische Antriebseinrichtung in besonderer Weise ausgebildet sein müßte. Insbesondere werden jegliche Maßnahmen beim Abladen der Hülsen eingespart, da diese wegen entsprechender Ausbildung der Bahn des Endlosförderers durch Schwerkraft von den Transportdornen in einen Hülsensammelbehälter herunterrutschen. Durch die Ausbildung der Transporteure als Transportdorne und das Überschieben der Hülsen von den Spulendornen auf diese Transportdorne werden die bekannten Mechanismen für die Eingriffe in die Hülsen eingespart und auch deren Steuerungen. Es ergibt sich eine erhebliche Vereinfachung, verbunden mit einer vergrößerten Universalität bei der Anwendung der Hülsenentfernungsvorrichtung.It is important for the invention that the sleeve transport devices have a revolving endless conveyor for the transport mandrels, which thus revolve on a self-contained path in a single plane. As a result, the motor drive device need not be designed to align the transport mandrels in mutually different planes, because the sleeves would have to be arranged differently in their sleeve receiving positions and in their sleeve unloading positions. Basically, the drive device is considerably simplified. The flexibility of the endless conveyor makes it possible to design its path in such a way that the transport mandrels assume the optimum position in their sleeve receiving or unloading positions without the motor drive device having to be designed in a special way. In particular, all measures during the unloading of the sleeves are saved, since due to the corresponding design of the endless conveyor track they slide down by gravity from the transport mandrels into a sleeve collecting container. By designing the transporters as transport mandrels and pushing the sleeves from the spools onto these transport mandrels, the known mechanisms for the interventions in the sleeves and also their controls are saved. This results in a considerable simplification, combined with an increased universality when using the sleeve removal device.

Eine besonders vorteilhafte konstruktive Ausgestaltung der Hülsenentfernungsvorrichtung bezüglich des in einer vertikalen Ebene umlaufenden Endlosförderers ergibt sich dadurch, daß der Endlosförderer zwei parallel um mit horizontalen Achsen angeordnete Umlenkräder laufende und von der motorischen Antriebseinrichtung beaufschlagbare Ketten aufweist, die von Dornträgern miteinander verbunden sind, von denen die Transportdorne vertikal nach außen abstehen. Der Endlosförderer besteht demgemäß aus insbesondere im Hinblick auf ihre Dauerhaltbarkeit bewährten Elementen, die durch die Hülsen in nur geringem Maße belastet werden und daher für eine entsprechend große Störungsfreiheit garantieren. Der Endlosförderer kann von einem herkömmlichen Elektromotor angetrieben werden, der mit einfachen Mitteln positionssteuerbar ist, so daß die Positionierungsgenauigkeit der Transportdorne gegenüber den Spulendornen des Spulengatters problemlos ist.A particularly advantageous constructive embodiment of the sleeve removal device with respect to the endless conveyor rotating in a vertical plane results from the fact that the endless conveyor has two chains which run parallel to deflection wheels arranged with horizontal axes and can be acted upon by the motor drive device and which are connected to one another by mandrel carriers, of which the Project the transport mandrels vertically outwards. Accordingly, the endless conveyor consists of elements which have been tried and tested, in particular with regard to their durability, which are only slightly loaded by the sleeves and therefore guarantee a correspondingly high degree of freedom from interference. The endless conveyor can be driven by a conventional electric motor become, which is position-controllable with simple means, so that the positioning accuracy of the transport mandrels relative to the spindles of the creel is problem-free.

Zweckmäßigerweise sind die Transportdorne vom Endlosförderer von ihren Hülsenaufnahmestellungen unter vertikaler Aufrichtung in die Hülsenabladestellungen zu fördern. Es bedarf infolgedessen keiner Sicherung der Hülsen auf den Transportdornen gegen Herabfallen. Vielmehr kann der Endlosförderer die leeren Hülsen problemlos transportieren, bis sie in den Hülsenaufnahmestellungen vom Transportdorn in den Hülsensammelbehälter abrutschen.The conveyor mandrels are expediently to be conveyed by the endless conveyor from their tube receiving positions with vertical erection into the tube unloading positions. As a result, the sleeves on the transport mandrels need not be secured against falling. Rather, the endless conveyor can easily transport the empty tubes until they slide from the transport mandrel into the tube collecting container in the tube receiving positions.

Eine besonders große Abladesicherheit ist dann gegeben, wenn der Endlosförderer oberhalb des Hülsensammelbehälters mit einem überwiegend horizontalen Trum versehen ist, von dem die Transportdorne vertikal abwärts weisen.A particularly high level of unloading security is provided if the endless conveyor is provided above the sleeve collecting container with a predominantly horizontal run from which the transport mandrels point vertically downward.

Um die Hülsen von den Spulendornen des Spulengatters in einfacher Weise auf die Transportdorne zu verschieben, ist die Vorrichtung so ausgebildet, daß die Hülsenübernahmeeinrichtung je aufnahmebereitem Transportdorn einen die auf einem Spulendorn des Spulengatters befindliche Hülse hintergreifenden und bei Betätigung auf den Transportdorn überschiebenden Schieber aufweist. Mit den Schiebern können alle Hülsen gleichzeitig verschoben werden, so daß die Manipulationszeit klein ist. Der Schieber ist ein baulich besonders einfaches Mittel. Er erspart ein Umklammern der Hülse für das Verschieben.In order to move the sleeves from the spindles of the creel to the transport mandrels in a simple manner, the device is designed such that the sleeve transfer device has a transport mandrel for each receptacle that grips behind the sleeve located on a coil mandrel of the creel and pushes on the transport mandrel when actuated. With the slides, all sleeves can be moved simultaneously, so that the manipulation time is short. The slide is a structurally particularly simple means. It saves you from having to clasp the sleeve for moving.

Zweckmäßigerweise wird die Vorrichtung so ausgebildet, daß die Schieber mit jeweils einer fernsteuerbaren Betätigungseinrichtung beaufschlagbar sind, die einen vertikal verstellbaren horizontalen Zylinder hat, an dessen Zylinderstange einer der Schieber angebracht ist. Die Zylinder der Betätigungseinrichtung können als einfache Produkte massenfertigungsgerecht ausgestaltet werden. Die von ihnen aufzubringenden Verschiebekräfte sind problemlos gering.The device is expediently designed such that the slides can each be acted upon by a remote-controllable actuating device which has a vertically adjustable horizontal cylinder, on the cylinder rod of which one of the slides is attached. The cylinders of the actuating device can be designed as simple products for mass production. The displacement forces to be applied by them are easily low.

Um die Vorrichtung so auszubilden, daß die Schieber problemlos hin- und herbewegt werden können, ist die Vorrichtung so ausgebildet, daß die vertikal verstellbaren Zylinder aller Betätigungseinrichtungen an einer vertikal verschieblich geführten und von einem Vertikalantrieb beaufschlagbaren Verstellschiene angebracht sind. Mit Hilfe des Vertikalantriebs und der Verstellschiene können die Zylinder aller Betätigungseinrichtungen gemeinsam beaufschlagt werden, wofür der Vertikalantrieb entsprechend den an der Vorrichtung vorhandenen Energiequellen ausgebildet werden kann, z.B. als Antriebszylinder. Die gemeinsame Beaufschlagung aller Betätigungseinrichtungen ergibt einen entsprechenden Zeitgewinn.In order to design the device in such a way that the slides can be moved back and forth without any problems, the device is designed such that the vertically adjustable cylinders of all the actuating devices are attached to an vertically displaceably guided adjustment rail which can be acted upon by a vertical drive. With the help of the vertical drive and the adjustment rail, the cylinders of all actuating devices can be acted on together, for which purpose the vertical drive can be designed in accordance with the energy sources present on the device, e.g. as a drive cylinder. Applying all actuators together results in a corresponding time saving.

Die Vorrichtung ist besonders darin vorteilhaft, daß sie ein Fahrgestell hat, das auf einer gatternahen und -parallelen Bodenschiene rollbar und an einer Deckenschiene rollabstützbar ist, und das einen Fahrantrieb aufweist. Sie kann also längs einer Gatterseite verfahren werden, um nacheinander alle vertikalen Spulenreihen des Gatters von Hülsen zu befreien. Mit Hilfe der Schiene wird zugleich erreicht, daß die erforderliche Positionierungsgenauigkeit der Transportdorne in Bezug auf die Spulendorne horizontal und im Abstand zum Gatter mit einfachen Mitteln erreicht werden kann. Hierzu kann insbesondere dienen, daß die Bodenschiene eine Zahnstange hat, in die ein fahrantriebsbeaufschlagtes Rad eingreift. Will man nicht von der durch eine Verzahnung gegebenen räumlichen Zuordnung zwischen einem Fahrgestell und dem Spulengatter abhängig sein, beispielsweise um die Positionierungsgenauigkeit zu erhöhen, so wird die Vorrichtung dahingehend ausgebildet, daß das Fahrgestell mit einem den Fahrantrieb beeinflussenden Näherungsschalter versehen ist, der auf einen an der Bodenschiene angebrachten Kontakt reagiert. Auch andere Positionierungshilfen sind anwendbar.The device is particularly advantageous in that it has a chassis which can be rolled on a floor rail near and parallel to the gate and which can be roll supported on a ceiling rail, and which has a travel drive. It can therefore be moved along one side of the gate in order to successively free all vertical coil rows of the gate from sleeves. With the help of the rail it is at the same time achieved that the required positioning accuracy of the transport mandrels with respect to the coil mandrels can be achieved horizontally and at a distance from the gate with simple means. This can serve in particular that the bottom rail has a rack, in which a wheel actuated by the drive engages. If you do not want to be dependent on the spatial association between a chassis and the creel given by a toothing, for example to increase the positioning accuracy, the device is designed in such a way that the chassis is provided with a proximity switch influencing the travel drive, which on a the contact attached to the floor rail reacts. Other positioning aids can also be used.

Die schienengebundene Anordnung der Hülsenentfernungsvorrichtung in Bezug auf das Spulengatter bietet die vorteilhafte Möglichkeit, daß sie gemeinsam mit einer gesteuert verfahrbaren Spulenbestückungseinrichtung auf der gatternahen und -parallelen Bodenschiene angeordnet ist. Infolgedessen können der Spulenbestückungsvorgang und der Hülsenentfernungsvorgang aufeinander abgestimmt werden. Die Abstimmung liegt zunächst hinsichtlich der räumlichen Anordnung der Entfernungsvorrichtung und der Bestückungseinrichtung durch die gemeinsame Bodenschiene zum Spulengatter vor. Darüber hinaus kann aber auch eine zeitliche Abstimmung erreicht werden, indem die Hülsenentfernungsvorrichtung und die Spulenbestückungseinrichtung gleichzeitig eingesetzt werden, nämlich dann, wenn durch die Hülsenentfernungsvorrichtung bereits hinreichend Platz für den Einsatz der Spulenbestückungseinrichtung am Spulengatter geschaffen wurde.The rail-bound arrangement of the sleeve removal device in relation to the creel offers the advantageous possibility that it is arranged together with a controllably movable coil placement device on the gate-near and parallel bottom rail. Consequently the coil assembly process and the sleeve removal process can be coordinated. The coordination is initially available with regard to the spatial arrangement of the removal device and the placement device through the common bottom rail to the creel. In addition, a timing can also be achieved by using the sleeve removal device and the bobbin loading device simultaneously, namely when sufficient space has already been created by the sleeve removal device for the use of the bobbin loading device on the creel.

Besonders vorteilhaft wird die Vorrichtung dadurch ausgebildet, daß sie eine gatterabzugseitige Ruhestellung und die Bestückungseinrichtung eine dem anderen Gatterende benachbarte Ruhestellung aufweist, daß sie zum Entfernen von Spulenhülsen an der der Ruhestellung der Bestückungeinrichtung nächstliegenden Dornreihe steuerbar ist, von der aus sie die Spulenhülsen von den Spulstellen spulenreihenweise nacheinander bis einschließlich der ihrer eigenen Ruhestellung nächstliegenden Dornreihe zu entfernen vermag, und daß die Bestückungseinrichtung während des Betriebs der Hülsenentfernungsvorrichtung zu den hülsenfreien Gatterreihen steuerbar ist. Durch die Anordnung der Ruhestellen an je einem Gatterende wird Platz gespart und steht genügend Raum zur Verfügung, beispielsweise um bei der Hülsenentfernungseinrichtung den Hülsensammelbehälter zu leeren oder bei der Spulenbestückungseinrichtung vollbewickelte Spulen aufzuliefern.The device is particularly advantageously designed in that it has a rest position on the take-off side and the loading device has a rest position adjacent to the other end of the gate, that it is controllable for removing bobbin sleeves on the row of mandrels closest to the rest position of the loading device, from which they remove the bobbin sleeves from the winding positions one after the other in rows up to and including the row of mandrels closest to their own rest position, and that the assembly device can be controlled during the operation of the sleeve removal device to the sleeve-free gate rows. The arrangement of the resting points at each end of the gate saves space and there is enough space available, for example in order to empty the tube collecting container in the tube removal device or to supply fully wound bobbins in the tube loading device.

Vorteilhafterweise ist die Vorrichtung so ausgebildet, daß der Fahrantrieb der Hülsenentfernungseinrichtung und/oder der Bestückungseinrichtung von einem ein Aufsteckmuster des Spulengatters für die Garnspulen berücksichtigenden Rechner steuerbar sind. Mit Hilfe der Steuerung des Fahrantriebs entsprechend einem Aufsteckmuster des Spulengatters kann beispielsweise erreicht werden, daß die Hülsenentfernungseinrichtung in einer ersten Spulenaufnahmestellung vor einer Dornreihe des Gatters nur einen Teil der Hülsen entnimmt, nämlich diejenigen, die einer bestimmten Garnsorte zugeordnet sind. Das ist insbesondere wichtig, wenn das Gatter mustergemäß bestückt und seine Spulen nur teilweise abgewickelt sind. Infolgedessen werden beim Entfernen von Hülsen vom Spulengatter alle einer einzigen Garnsorte zugeordneten Hülsen nacheinander von den Spulendornen entfernt, während die Hülsen bzw. mit Resten bewickelten Hülsen einer anderen Garnsorte während eines späteren Entfernungslaufs der Entfernungsvorrichtung entfernt werden. Sammelbehälter für Hülsen enthalten dann nur solche gleicher Garnsorten. Dementsprechend ist es auch möglich, die Bestückungseinrichtung so mit dem Rechner zu steuern, daß sie das Gatter nur mit Spulen einer einzigen Garnsorte bestückt, beispielsweise mit Spulen einer bestimmten Garnfarbe. Es brauchen nur Spulen einer einzigen Garnsorte durch die Bestückungseinrichtung geladen werden, die dann mustergerecht auf die Spulendorne des Spulengatters überschoben werden. Dabei können Spulstellen aller vertikalen Gatterreihen erreicht und bestückt werden, ohne daß die Bestückungseinrichtung vor ihrer vollständigen Entladung erneut bestückt werden müßte, um dem Aufsteckmuster gerecht werden zu können.The device is advantageously designed in such a way that the travel drive of the tube removal device and / or the loading device can be controlled by a computer that takes into account a plug-on pattern of the bobbin creel for the yarn bobbins. With the help of the control of the travel drive according to a plug-on pattern of the bobbin creel, it can be achieved, for example, that the tube removal device in a first bobbin take-up position in front of a row of mandrels of the gate removes only a part of the bobbins, namely those which are of a certain type of yarn assigned. This is particularly important if the gate is equipped according to the pattern and its coils are only partially unwound. As a result, when the tubes are removed from the creel, all the tubes associated with a single type of yarn are removed one after the other from the spindles, while the tubes or sleeves of another yarn with the remainder are removed during a later removal run of the removal device. Collection containers for tubes then contain only those of the same thread types. Accordingly, it is also possible to control the loading device with the computer in such a way that it only loads the creel with bobbins of a single type of yarn, for example with bobbins of a specific yarn color. Only bobbins of a single type of yarn need to be loaded by the loading device, which are then pushed onto the bobbin pins of the bobbin according to the pattern. In this case, winding positions of all vertical rows of gates can be reached and loaded without the loading device having to be loaded again before it is completely discharged in order to be able to do justice to the plug-on pattern.

Die in den Fig.1 bis 3 dargestellte Hülsenentfernungsvorrichtung 13 wird dazu benutzt, die Hülsen 10 eines Spulengatters 11 von Spulendornen 12 zu entfernen. Der Begriff Spulengatter steht dabei ganz allgemein für Einrichtungen, bei denen Spulen zumindest reihenweise angeordnet sind, also vertikal übereinander. In Fig.6 ist als Spulengatter 11 eine aufgereihte Anordnung von drei Gatterwagen 43 oder Drehrahmen dargestellt, die eine Gatterhälfte bilden. Die andere, nicht dargestellte Gatterhälfte ist symmetrisch zu der strichpunktierten Linie 44 angordnet. Jeder Gatterwagen 43 ist innen, also der Linie 44 zugewendet, mit Spulen 42 bestückt, von denen die Fäden F durch eine nicht dargestellte Wickelmaschine abgezogen werden. Die von der Wickelmaschine abgezogene Fadenschar 41 aller Einzelfäden F verläuft beispielsweise wie dargestellt. Die Gatterwagen 43 sind doppelseitig bestückbar, so daß auf der nach außen gewendeten Wagenseite die dort vorhandenen leeren Hülsen 10 der abgewickelten Spulen entfernt und neue, vollgewickelte Spulen 42' aufgesteckt werden können. Die zum Entfernen der Hülsen 10 erforderliche Hülsenentfernungsvorrichtung 13 hat als wesentlichen Bestandteil einer nicht näher bezeichneten Hülsentransporteinrichtung einen umlaufenden flexiblen Endlosförderer 17, der vertikal angeordnet ist. Mit ihm werden als Transportdorne 14 ausgebildete Transporteure in der vertikalen Förderebene bewegt. Die Transportdorne 14 sind in derselben Teilung T vertikal übereinander angeordnet, wie die Spulendorne 12 des Spulengatters. Der Endlosförderer 17 ist in der Lage, die Transportdorne 14 hinreichend exakt fluchtend mit den Spulendornen 12 anzuordnen. Es ist dann möglich, die Hülsen 10 von den Spulendornen 12 auf die Transportdorne 14 zu verschieben.The sleeve removal device 13 shown in FIGS. 1 to 3 is used to remove the sleeves 10 of a creel 11 from coil mandrels 12. The term coil creel stands quite generally for devices in which coils are arranged at least in rows, ie vertically one above the other. 6 shows a lined-up arrangement of three gate carriages 43 or rotating frames, which form a gate half, as the coil gate 11. The other, not shown gate half is arranged symmetrically to the dash-dotted line 44. Each gate carriage 43 is fitted with spools 42 on the inside, ie facing the line 44, from which the threads F are drawn off by a winding machine (not shown). The thread group 41 of all individual threads F drawn off the winding machine runs, for example, as shown. The gate carriages 43 can be fitted on both sides, so that the empty sleeves 10 of the unwound coils present there can be removed on the outside of the carriage and new, fully wound coils 42 'can be attached. The sleeve removal device 13 required for removing the sleeves 10 has, as an essential component of a sleeve transport device (not described in more detail), a rotating, flexible endless conveyor 17 which is arranged vertically. It is used to move 14 trained transporters in the vertical conveyor plane. The transport mandrels 14 are arranged vertically one above the other in the same division T as the coil mandrels 12 of the creel. The endless conveyor 17 is able to arrange the transport mandrels 14 in a sufficiently precise alignment with the spool mandrels 12. It is then possible to move the sleeves 10 from the spindles 12 onto the transport mandrels 14.

Die Transportdorne 14 sind vom Endlosförderer 17 mittels Dornträger 22 gehalten, die in auf die im übrigen gegebene Ausbildung des Endlosförderers abgestimmter Weise ausgebildet sind. Der dargestellte Endlosförderer 17 besteht hier aus zwei parallel angeordneten Ketten 21, die um Umlenkräder 20 herum geführt sind. Dementsprechend besteht der Dornträger 22 aus die Ketten mechanisch miteinander verbindenden Stegen, in deren Mitte die Dorne 14 angeordnet sind. Anstelle der Ketten 21 und Umlenkräder 20 können auch andere flexible Elemente verwendet werden, beispielsweise für das Tragen der Dorne 14 geeignete flexible Bänder oder Gurte, die zum Antrieb eine Verzahnung aufweisen und deren Kanten von C-förmigen Profilen geführt sind, so daß die gewünschte Ausrichtung der Transportdorne 14 vertikal nach außen gewährleistet wird.The transport mandrels 14 are held by the endless conveyor 17 by means of mandrel carriers 22 which are designed in a manner which is coordinated with the otherwise given configuration of the endless conveyor. The endless conveyor 17 shown here consists of two chains 21 arranged in parallel, which are guided around deflection wheels 20. Accordingly, the mandrel carrier 22 consists of webs mechanically connecting the chains, in the middle of which the mandrels 14 are arranged. Instead of the chains 21 and deflection wheels 20, other flexible elements can also be used, for example flexible belts or belts suitable for carrying the mandrels 14, which have a toothing for the drive and whose edges are guided by C-shaped profiles, so that the desired orientation the transport mandrels 14 is guaranteed vertically to the outside.

Die Anordnung der Ketten 21 ist derart, daß ein vertikales Trum 17'' genügend lang ist, um eine der Anzahl der Spulendorne 12 entsprechende Anzahl von Transportdornen 14 vertikal übereinander anordnen zu können. Oberhalb des höchstgelegenen Spulendorns 12 erfolgt eine Umlenkung des Endlosförderers 17 um Umlenkräder 20, zu einem Trum 17', von dem die Dorne 14 darstellungsgemäß vertikal nach unten ragen. Das Trum 17' befindet sich oberhalb eines Hülsensammelbehälters 18, so daß die von den Dornen 14 transportierten Hülsen 10 abrutschen und in den Hülsensammelbehälter 18 fallen, wo sie gesammelt werden. Um ein Vorbeifallen der Hülsen 10 am Behälter 18 auszuschließen, ist ein Schutzleder 45' oder dergleichen vorhanden.The arrangement of the chains 21 is such that a vertical run 17 ″ is long enough to be able to vertically stack a number of transport mandrels 14 corresponding to the number of spool mandrels 12. Above the highest spool mandrel 12 there is a deflection of the endless conveyor 17 by deflection wheels 20, to a strand 17 ', from which the mandrels 14 project vertically downward as shown. The strand 17 'is located above a tube collecting container 18, so that the tubes 10 transported by the mandrels 14 slide off and fall into the tube collecting container 18, where they are collected. To prevent the sleeves 10 from falling past the container 18, protective leather 45 'or the like is present.

Zum Antrieb des Endlosförderers 17 dient eine auf einem Gestell 45 der Vorrichtung 13 gestellfeste Antriebseinrichtung 15, im wesentlichen bestehend aus einem Antriebsmotor, einer davon beaufschlagten Antriebskette 15' und einem von dieser Kette 15' angetriebenen Antriebsrad 15'', welches mit einem Umlenkrad 20 gleichachsig angeordnet ist, also ebenfalls mit horizontaler Achse 19, so daß ein Einschalten der Antriebseinrichtung 15 zu einem Verstellen der Ketten 21 führt, und demgemäß zu einem Verstellen der Dorne 14.To drive the endless conveyor 17, a drive device 15 fixed on a frame 45 of the device 13 is used, consisting essentially of a drive motor, a drive chain 15 'acted upon by it and a drive wheel 15''driven by this chain 15', which is coaxial with a deflection wheel 20 is arranged, thus also with a horizontal axis 19, so that switching on the drive device 15 leads to an adjustment of the chains 21, and accordingly to an adjustment of the mandrels 14.

Gemäß Fig.2 ist die Hülsenentfernungsvorrichtung 14 mit einer einzigen Reihe vertikal übereinander angeordneter Transportdorne 14 versehen. Sie kann infolgedessen jeweils nur eine einzige Reihe von Spulendornen 12 des Spulengatters 11 von Hülsen 10 entladen und muß infolgedessen gatterparallel verschieblich sein, falls nicht davon ausgegangen wird, daß Gatterwagen 43 verwendet und jeweils vor einer ortsfesten Vorrichtung 13 in Hülsenabladestellungen verschoben werden. Infolgedessen ist die Vorrichtung 13 mit einem Fahrgestell 29 versehen, welches starrer Bestandteil des Gestells 45 ist und zwei Fahrrollen 44 aufweist, die auf einer Bodenschiene 30 rollbar und das Gestell 45 führend abgestützt sind. Sie übertragen das Gewicht der Vorrichtung 13 auf die Bodenschiene 30. Die Bodenschiene 30 ist gatteraussenseitig parallel zum Gatter 11 angeordnet, wie Fig.6 zeigt. Eine horizontale Abstützung der Vorrichtung 13 erfolgt mit einer Abstützrolle 46 vertikal oben an einer Deckenschiene 31 oder an einer Gatterschiene, an der die Abstützrolle 46 infolge der in Fig.1 rechtslastigen Ausbildung der Vorrichtung 13 anliegt. Dem Verfahren der Vorrichtung 13 dient ein steuerbarer Fahrantrieb 32, der z.B. aus einem Elektromotor besteht, welcher mittels eines Transmissionselements 47, beispielsweise eines formschlüssigen Antriebsriemens, ein Abtriebsrad 48 eines Untersetzungsgetriebes 49 antreibt, das mit einem Ritzel 50 in ein Rad 33 eingreift, nämlich ein Zahnrad, das in die Verzahnung einer Zahnstange 31 formschlüssig eingreift, die sich an der Bodenschiene 30 befindet. Der Antriebsmotor des Fahrantriebs 32 kann so gesteuert werden, daß die Vorrichtung 13 genügend genau horizontal in Bezug auf die Spulendorne 12 positioniert wird. Hierzu dient erforderlichenfalls ein am Fahrgestell 29 befindlicher Näherungsschalter 34, der mit einem Kontakt 35 der Bodenschiene 30 zusammenwirkt. Dieser Kontakt 35 ist beispielsweise eine Befestigungsschraube der Zahnstange 31 an der Bodenschiene 30. Es kann auch ein zusätzlicher Bodenkontakt 35' als Vorkontakt verwendet werden, beispielsweise um die Fahrgeschwindigkeit der Vorrichtung 13 so herabzusetzen, daß sie bei Erreichen der durch den Kontakt 35 bestimmten Position sofort positionsgenau angehalten werden kann. Für eine genaue Positionierung ist es oft nötig, den Näherungsschalter 34 horizontal einstellbar am Fahrgestell 29 zu befestigen.2, the sleeve removal device 14 is provided with a single row of transport mandrels 14 arranged vertically one above the other. As a result, it can only unload a single row of spools 12 of the creel 11 from sleeves 10 and must consequently be displaceable parallel to the gate, unless it is assumed that gate carriages 43 are used and in each case are moved in front of a stationary device 13 in tube unloading positions. As a result, the device 13 is provided with a chassis 29, which is a rigid component of the frame 45 and has two castors 44, which can be rolled on a floor rail 30 and the frame 45 is supported in a leading manner. They transfer the weight of the device 13 to the bottom rail 30. The bottom rail 30 is arranged on the outside of the gate parallel to the gate 11, as shown in FIG. A horizontal support of the device 13 takes place with a support roller 46 vertically at the top on a ceiling rail 31 or on a gate rail on which the support roller 46 bears due to the right-hand design of the device 13 in FIG. The device 13 is operated by a controllable travel drive 32, which consists, for example, of an electric motor which, by means of a transmission element 47, for example a positive drive belt, drives an output gear 48 of a reduction gear 49, which engages with a pinion 50 in a wheel 33, namely a Gear that engages in the toothing of a toothed rack 31, which is located on the bottom rail 30. The drive motor of the travel drive 32 can be controlled so that the device 13 is positioned sufficiently precisely horizontally with respect to the spool mandrel 12. If necessary, a proximity switch 34 located on the chassis 29, which interacts with a contact 35 of the floor rail 30, is used for this purpose. This contact 35 is, for example, a fastening screw of the toothed rack 31 to the floor rail 30. An additional floor contact 35 'can also be used as a pre-contact, for example in order to reduce the driving speed of the device 13 so that it immediately reaches the position determined by the contact 35 can be stopped precisely. The proximity switch is often required for precise positioning 34 horizontally adjustable to attach to the chassis 29.

Um die leeren Hülsen 10 von den Spulendornen 12 auf die Transportdorne 14 zu verschieben, ist die Vorrichtung 13 mit Hülsenübernahmeeinrichtungen 16 versehen. Je aufnahmebereitem Transportdorn 14 ist eine Übernahmeeinrichtung 16 vorhanden. Jede Übernahmeeinrichtung 16 besteht im wesentlichen aus einer horizontal angeordneten fernsteuerbaren Betätigungseinrichtung 24 und einem davon betätigbaren Schieber 23. Der Schieber 23 ist von der Betätigungseinrichtung 24 horizontal verstellbar. Als Betätigungsvorrichtung ist ein horizontal angeordneter Zylinder 25 vorhanden, an dessen Kolbenstange 26 der Schieber 23 angebracht ist. Alle Zylinder 25 bzw. Betätigungseinrichtungen 24 sind an einer vertikal verstellbaren Verstellschiene 28 angebracht, die von Führungsrollen 52 geführt ist. Die Verstellung der Verstellschiene 28 erfolgt mit Hilfe eines Vertikalantriebs 27, der in den Fig.1,2 als Druckzylinder ausgebildet ist. Infolgedessen können alle Zylinder 22,27 anforderungsgemäß z.B. mit Druckluft beaufschlagt werden, um ihre Kolbenstangen zu verstellen.In order to move the empty tubes 10 from the spools 12 to the transport pins 14, the device 13 is provided with tube transfer devices 16. A takeover device 16 is provided for each transport mandrel 14 that is ready to receive. Each take-over device 16 essentially consists of a horizontally arranged remote-controllable actuating device 24 and a slide 23 which can be actuated thereby. The slide 23 is horizontally adjustable by the actuating device 24. A horizontally arranged cylinder 25 is provided as the actuating device, on the piston rod 26 of which the slide 23 is attached. All cylinders 25 and actuating devices 24 are attached to a vertically adjustable adjustment rail 28 which is guided by guide rollers 52. The adjustment rail 28 is adjusted with the aid of a vertical drive 27, which is designed as a pressure cylinder in FIGS. As a result, all cylinders 22, 27 can be e.g. be pressurized with air to adjust their piston rods.

Fig.4a zeigt in einer Seitenansicht einen Dornträger 53 des Spulengatters 11 mit einem Spulendorn 12. Auf derselben Höhe ist der Dorn 14 mit Hilfe des Dornträgers 22 der Hülsentransporteinrichtung bzw. des Endlosförderers 17 angeordnet. Der Schieber 23 befindet sich entweder in einer Stellung, in der er den Dornträger 53 umgreift, oder in einer Stellung zwischen den Dornen 12,14. Die Verstellung des Schiebers 23 aus der einen in die andere Stellung zwischen den Dornen 12,14 erfolgt mit Hilfe des Zylinders 25, der die Kolbenstange 26 in Richtung des Pfeils 54 verstellt, so daß der Schieber 23 entsprechend verstellt wird. Dabei verschiebt er die Hülse 10 vom Dorn 12 auf den Dorn 14. Das erfolgt während der Stillstandszeit der Vorrichtung 13 vor einer Dornreihe. Die Bewegungsphasen beim Überschieben einer Hülse im Einzelnen sind in Fig.5 dargestellt. Phase 5.1 zeigt in der unteren Darstellung den Schieber zwischen den Dornen 12,14 in einer durch die Verstellschiene 28 abgesenkten Stellung. Die Hülse 10 sitzt leer auf dem Dorn 12. Phase 5.2 zeigt die Verstellung des Schiebers 23 auf abgsenktem Niveau unterhalb der Hülse 10. Phase 5.3 zeigt das Anheben des Schiebers 23 in eine Stellung gemäß Fig.4a rechts, in der also der Schieber 23 den Dornhalter 53 mit einer Ausnehmung 23' umgreift, wobei die Hülse 10 hintergriffen wird. Phase 5.4 zeigt das Überschieben der Hülse 10 vom Dorn 12 auf den Dorn 14 und Phase 5.5 das Absenken des Schiebers 23 in eine Stellung gemäß Phase 5.1. Die Hülse 10 ist jedoch überschoben und kann von der Transporteinrichtung gemeinsam mit den anderen Hülsen 10 der anderen Transportdorne 14 vom Endlosförderer 17 in den Sammelbehälter 18 gefördert werden. Währenddessen kann die Vorrichtung 13 von einer Dornreihe zu einer nächsten Dornreihe verfahren werden. Es ergibt sich eine dementsprechende erhebliche Zeiteinsparung.4 a shows a side view of a mandrel carrier 53 of the creel 11 with a coil mandrel 12. At the same height, the mandrel 14 is arranged with the aid of the mandrel carrier 22 of the sleeve transport device or of the endless conveyor 17. The slider 23 is either in a position in which it engages around the mandrel carrier 53 or in a position between the mandrels 12, 14. The adjustment of the slide 23 from one position to the other between the mandrels 12, 14 takes place with the aid of the cylinder 25, which adjusts the piston rod 26 in the direction of the arrow 54, so that the slide 23 is adjusted accordingly. He moves the sleeve 10 from the mandrel 12 to the mandrel 14. This takes place during the downtime of the device 13 in front of a row of mandrels. The movement phases when sliding over a sleeve are shown in detail in FIG. 5. In the lower illustration, phase 5.1 shows the slide between the mandrels 12, 14 in a one lowered by the adjustment rail 28 Position. The sleeve 10 sits empty on the mandrel 12. Phase 5.2 shows the adjustment of the slide 23 at the lowered level below the sleeve 10. Phase 5.3 shows the lifting of the slide 23 into a position according to FIG. 4a on the right, in which the slide 23 therefore Grips mandrel holder 53 with a recess 23 ', the sleeve 10 being engaged behind. Phase 5.4 shows the sliding of the sleeve 10 from the mandrel 12 onto the mandrel 14 and phase 5.5 the lowering of the slide 23 into a position according to phase 5.1. However, the sleeve 10 is pushed over and can be conveyed by the transport device together with the other sleeves 10 of the other transport mandrels 14 from the endless conveyor 17 into the collecting container 18. In the meantime, the device 13 can be moved from one row of mandrels to the next row of mandrels. This results in a considerable time saving.

Gemäß Fig.6 wird die Hülsenentfernungseinrichtung 13 gemeinschaftlich mit einer Bestückungseinrichtung 36 eingesetzt. Letztere hat einen Bestückungswagen 54, der auf der Bodenschiene 30 verfahrbar ist und eine vertikale Reihe von Transportdornen 55 aufweist, die mit vollbewickelten Spulen 42 bestückt werden. Die Spulenübergabe ist durch den Pfeil 56 symbolisiert. Die Spulenübergabe erfolgt durch eine nicht näher dargestellte Spulenübergabeeinrichtung 57, die beispielsweise als roboterähnliche Handhabungseinrichtung ausgebildet ist, oder als eine der Hülsenentfernungsvorrichtung ähnliche Vorrichtung, bei der die Spulen jedoch in umgekehrter Richtung überschoben werden, also von Transportdornen auf die Dorne 55 des Bestükckungswagens 54.According to FIG. 6, the sleeve removal device 13 is used jointly with an equipping device 36. The latter has a pick-up carriage 54 which can be moved on the bottom rail 30 and has a vertical row of transport mandrels 55 which are fitted with fully wound coils 42. The coil transfer is symbolized by arrow 56. The bobbin transfer takes place through a bobbin transfer device 57 (not shown in more detail), which is designed, for example, as a robot-like handling device, or as a device similar to the tube removal device, but in which the bobbins are pushed over in the opposite direction, i.e. from transport mandrels onto the mandrels 55 of the pick-and-place carriage 54.

Die Hülsenentfernungsvorrichtung 13 hat eine Ruhestellung 37 am gatterabzugseitigen Ende des Gatters 11, während der Spulenwagen 54 bzw. die Bestückungseinrichtung 36 am entgegengesetzten Gatterende eine Ruhestellung 38 aufweist. Es ergibt sich eine dementsprechend kompakte Gesamtanordnung. Zum Entfernen der Hülsen 10 wird die Vorrichtung 13 gemäß Fig.6 aus ihrer Ruhestellung in ihre erste Arbeitsstellung 58 verfahren, in der ihre Transportdorne 14 den gatterauswärts weisenden Dornen 12 der Dornreihe 39 gegenüberliegen. Nach Entfernung der Hülsen 10 von den Dornen der Dornreihe 39 wird die Vorrichtung 13 zur Dornreihe der Arbeitsstellung 59 gesteuert, usw., bis alle Hülsen 10 der nach außen weisenden Dorne 12 der Gatterwagen 43 bzw. der Drehrahmen entfernt sind. Danach kehrt die Vorrichtung 13 in die Ruhestellung 37 zurück. Der Bestückungswagen 54 wird von der Ruhestellung 38 aus zunächst bis zur Dornreihe 39 verschoben, um dort die vollgewickelten Spulen 42' sämtlich oder teilweise zu übergeben. Er wird so gesteuert, daß er während der Tätigkeit der Vorrichtung 13 die freigewordenen Dorne 12 bestückt, sofern die räumliche Abmessung der Vorrichtung 13 das zuläßt. Letztere kann so ausgestaltet werden, daß die Bestückungseinrichtung 36 bzw. der Bestückungswagen 54 jedenfalls dann mit der Bestückung des ersten Gatterwagens beginnen kann, wenn von dessen sämtlichen Dornen 12 die Hülsen 10 entfernt wurden. Infolgedessen ergibt sich die aus Fig.6 ersichtliche schrittweise Bestückung sämtlicher Reihen aller Gatterwagen 43. Das Entfernen der leeren Hülsen 10 und das Bestücken mit vollgewickelten Spulen 42' kann während des Fadenabzugs von den Spulen 42 erfolgen, so daß insofern Stillstandszeiten vermieden werden.The sleeve removal device 13 has a rest position 37 at the gate withdrawal end of the gate 11, while the coil carriage 54 or the placement device 36 has a rest position 38 at the opposite gate end. The overall arrangement is accordingly compact. To remove the sleeves 10, the device 13 is moved according to FIG. 6 from its rest position into its first working position 58, in which its transport mandrels 14 lie opposite the mandrels 12 of the row 39 of mandrels pointing outward from the gate. After removing the sleeves 10 from the thorns of the Mandrel row 39, the device 13 for the mandrel row of the working position 59 is controlled, etc., until all sleeves 10 of the outwardly facing mandrels 12 of the gate carriage 43 or the rotating frame have been removed. The device 13 then returns to the rest position 37. The loading carriage 54 is initially shifted from the rest position 38 to the row of mandrels 39 in order to transfer all or part of the fully wound coils 42 'there. It is controlled in such a way that it populates the thorns 12 that have become free while the device 13 is operating, provided that the spatial dimension of the device 13 permits this. The latter can be designed in such a way that the assembly device 36 or the assembly carriage 54 can in any case begin to assemble the first gate carriage when the sleeves 10 have been removed from all of its mandrels 12. As a result, the gradual loading of all rows of all gate carriages 43 results, as can be seen in FIG. 6. The removal of the empty sleeves 10 and the loading with fully wound bobbins 42 'can take place during the thread take-off from the bobbins 42, so that downtimes can be avoided.

Mit der Hülsenentfernungsvorrichtung 13 können vollständig abgewickelte Spulenhülsen 10 entfernt werden, andererseits aber auch solche, auf denen sich noch Fadenreste unterschiedlicher Größe befinden. Demgemäß ist es möglich, beispielsweise nur vollständig abgelaufene Hülsen zu entfernen, die nur teilweise abgewickelten Spulen jedoch weiter zu verwenden. Hierzu kann die Vorrichtung 13 von einem Rechner gesteuert werden, der einem Aufsteckmuster des Spulengatters entsprechend Hülsen entfernt. Dementsprechend kann nachfolgend auch die Bestückungseinrichtung vom Rechner so gesteuert werden, daß lediglich die von Hülsen befreiten Spulendorne 12 des Gatters 11 neu bestückt werden.Fully unwound bobbin tubes 10 can be removed with the tube removal device 13, but also those on which there are still thread remnants of different sizes. Accordingly, it is possible, for example, to remove only completely expired sleeves, but to continue to use the partially unwound coils. For this purpose, the device 13 can be controlled by a computer which removes sleeves in accordance with a plug-on pattern of the creel. Accordingly, the assembly device can also be controlled by the computer in such a way that only the coil mandrels 12 of the gate 11, which have been freed from sleeves, are re-equipped.
