Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Positionieren von Hülsen auf einer Wickelwelle zu schaffen, die eine Positionierung mit schnellen Taktzeiten sowie mit hoher Genauigkeit ermöglichen.It is therefore an object of the present invention to provide a method and an apparatus for positioning sleeves on a winding shaft, which enable positioning with fast cycle times and with high accuracy.
Diese Aufgabe wird mit einem Verfahren mit den Merkmalen des Anspruches 1 sowie einer Vorrichtung mit den Merkmalen des Anspruches 7 gelöst.This object is achieved by a method having the features of claim 1 and a device having the features of
Bei dem erfindungsgemäßen Verfahren wird zunächst eine Hülse zu einem Greifer gefördert, wobei die Position der Hülse über mindestens einen Sensor erfasst wird. Abhängig von der erfassten Position der Hülse wird dann die Hülse von dem Greifer zu einem Endlosförderer bewegt, der die Hülse fördert, wobei dann eine nachfolgende Hülse wieder von dem Greifer zu dem Endlosförderer gefördert werden kann, bis die gewünschte Anzahl von Hülsen an dem Endlosförderer positioniert ist. Dadurch kann eine Ausrichtung der einzelnen Hülsen zueinander erfolgen, die in einem vorbestimmten Abstand an dem Endlosförderer gehalten sind. Die Einheit aus Hülsen an dem Endlosförderer kann dann an eine Wickelwelle übergeben werden, die auch nachträglich in die Hülsen hinein bewegt werden kann. Die Positionierung über den Endlosförderer hat den beträchtlichen Vorteil einer kurzen Taktzeit, da die einzelnen Hülsen nacheinander mit hoher Geschwindigkeit dem Endlosförderer zugeführt werden können. Zudem ist die Positionierung der Hülsen durch Erfassung der Position vergleichsweise genau möglich, wobei ein oder mehrere Sensoren für die Positionserfassung eingesetzt werden können, um dann die Steuerung des Endlosförderers und/oder des Greifers entsprechend vornehmen zu können. Dies erspart aufwändige Ausrichtarbeiten der einzelnen Hülsen an der Wickelwelle.In the method according to the invention, first a sleeve is conveyed to a gripper, wherein the position of the sleeve is detected by at least one sensor. Depending on the detected position of the sleeve, the sleeve is then moved by the gripper to an endless conveyor which conveys the sleeve, then a subsequent sleeve can be conveyed again from the gripper to the endless conveyor until the desired number of sleeves are positioned on the endless conveyor is. As a result, an alignment of the individual sleeves can take place relative to each other, which are held at a predetermined distance from the endless conveyor. The unit of sleeves on the endless conveyor can then be transferred to a winding shaft, which can also be subsequently moved into the sleeves. The positioning over the endless conveyor has the considerable advantage of a short cycle time, since the individual tubes can be fed one after the other at high speed to the endless conveyor. In addition, the positioning of the sleeves by detecting the position is relatively accurate possible, with one or more sensors can be used for the position detection, to then make the control of the endless conveyor and / or the gripper accordingly. This saves complex alignment work of the individual sleeves on the winding shaft.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird durch das Erfassen der Position der Hülse und das Bewegen der Hülse zu einem Endlosförderer der Spalt zwischen zwei benachbarten Hülsen eingestellt. Die Hülse kann von dem Greifer zu dem Endlosförderer mit höherer oder niedriger Geschwindigkeit gefördert werden, je nachdem, wie groß der Spalt zwischen zwei benachbarten Hülsen eingestellt werden soll. Dies ermöglicht eine flexible Anpassung auch während des Bestückens des Endlosförderers mit einzelnen Hülsen.According to a preferred embodiment of the invention, by detecting the position of the sleeve and moving the sleeve to an endless conveyor, the gap between two adjacent sleeves is adjusted. The sleeve may be conveyed from the gripper to the endless conveyor at a higher or lower speed, depending on how large the gap between two adjacent sleeves is to be adjusted. This allows flexible adaptation even during the placement of the endless conveyor with individual sleeves.
Für eine positionsgenaue Anordnung der Hülsen sind diese vorzugsweise klemmend an dem Endlosförderer fixiert, wobei der Endlosförderer hierfür ein oder mehrere umlaufende Bänder aufweist, die an einer Außenseite der Hülsen anlegbar sind. Der Endlosförderer kann dann nach der Positionierung der Hülsen zur Wickelwelle verfahren werden oder umgekehrt wird die Wickelwelle zu dem Endlosförderer verfahren, damit die Wickelwelle in die Hülsen eingesteckt wird und dann die Hülsen über eine Spannvorrichtung an der Wickelwelle fixiert werden. Anschließend kann dann der Endlosförderer von den Hülsen entfernt werden, wobei hierfür der Endlosförderer vorzugsweise zwei Arme aufweist, die auseinanderfahrbar oder -schwenkbar sind, um die Hülsen freizugeben.For a positionally accurate arrangement of the sleeves they are preferably fixed by clamping on the endless conveyor, wherein the endless conveyor for this purpose has one or more circumferential bands which can be applied to an outer side of the sleeves. The endless conveyor can then be moved to the positioning of the sleeves to the winding shaft or vice versa, the winding shaft is moved to the endless conveyor, so that the winding shaft is inserted into the sleeves and then the sleeves are fixed by a tensioning device on the winding shaft. Then the endless conveyor can be removed from the sleeves For this purpose, the endless conveyor preferably has two arms that can be moved apart or swiveled to release the sleeves.
Für eine besonders kurze Taktzeit und eine exakte Positionierung wird eine Hülse jeweils an dem Greifer von Backen gegriffen und dem Endlosförderer zugeführt.For a particularly short cycle time and exact positioning a sleeve is gripped on the gripper of jaws and fed to the endless conveyor.

Dadurch kann eine Positionierung der Hülsen entlang des Endlosförderers mit einem vorbestimmten Abstand erfolgen, wobei die Hülsen dann gleichzeitig auf die Wickelwelle übergeben werden, was zu einer vergleichsweise kurzen Taktzeit und einer hohen Positionsgenauigkeit führt. Zudem können mit der erfindungsgemäßen Vorrichtung Hülsen unterschiedlicher Länge problemlos verarbeitet werden und die Positionierung der Hülsen kann automatisch erfolgen.The apparatus according to the invention comprises a conveyor for conveying a sleeve to a gripper, at least one sensor for detecting the position of the sleeve, and means for moving the sleeve from the gripper to an endless conveyor depending on the gripping position of the sleeve, more than one endless conveyor Sleeves are simultaneously positioned around the winding shaft.

Die Hülse kann dabei zwischen mehreren umlaufenden Bändern des Endlosförderers festgeklemmt werden, beispielsweise mittels zwei, drei oder vier Bändern, die vorzugsweise gemeinsam über einen oder mehrere Antriebe bewegbar sind. Die Bänder können dabei an zwei Armen verfahrbar angeordnet sein, so dass die Bänder nach dem Positionieren der Hülsen auf der Wickelwelle von den Hülsen entfernt werden. Zudem kann durch das Verfahren der Arme der Endlosförderer auch auf unterschiedliche Durchmesser der Hülsen eingestellt werden.The endless conveyor preferably has at least two circumferential bands, by means of which the sleeves can be clamped. The band may be made of an elastic material, in particular a rubber or a foamed material, and come to rest on an outer surface of the sleeve. The sleeve can be clamped between a plurality of circumferential bands of the endless conveyor, for example by means of two, three or four bands, which are preferably movable together via one or more drives. The bands can be arranged to be movable on two arms, so that the bands are removed after positioning the sleeves on the winding shaft of the sleeves. In addition, by the method of the arms of the endless conveyor can be adjusted to different diameters of the sleeves.
Gemäß einer weiteren Ausgestaltung der Erfindung umfasst der Greifer einen aus Bürsten gebildeten Kanal zum Durchführen der Hülsen. An dem Kanal können die Hülsen abgebremst oder angehalten werden, um eine Vorderkante einer Hülse über den Sensor zu erfassen, um dann die weitere Bewegung der Hülse entsprechend der Position der Vorderkante der Hülse zu steuern. Dadurch kann der Abstand zwischen zwei Hülsen positionsgenau eingestellt werden, und die Hülse wird mit mechanisch einfach ausgebildeten Mitteln am Greifer gehalten.According to a further embodiment of the invention, the gripper comprises a channel formed from brushes for passing the sleeves. The sleeves may be braked or stopped on the channel to engage a leading edge of a sleeve over the sensor to then control the further movement of the sleeve according to the position of the leading edge of the sleeve. Thereby, the distance between two sleeves can be set accurately positioned, and the sleeve is held by mechanically simple means on the gripper.
Als Sensor zur Erfassung der Position der Hülse kann ein optischer Sensor eingesetzt werden, beispielsweise eine Lichtschranke mit einem Laserstrahl, so dass eine Vorderkante einer Hülse mit hoher Genauigkeit erfasst werden kann.As a sensor for detecting the position of the sleeve, an optical sensor can be used, for example, a light barrier with a laser beam, so that a leading edge of a sleeve can be detected with high accuracy.
Die Fördereinrichtung weist vorzugsweise einen Schieber auf, der zwischen einer Aufnahmeposition, in der eine Hülse von oben in eine Aufnahme vor dem Schieber einfügbar ist, und einer vorderen Endposition, an der eine Hülse in Längsrichtung aus der Aufnahme verschoben ist, bewegbar ist. Dabei kann oberhalb der Aufnahme eine Vielzahl von Hülsen in einem Magazin angeordnet sein, die dann einzeln nacheinander in die Aufnahme eingefügt werden, wenn diese über den Schieber entleert wurde. Über den Schieber können dann eine oder mehrere Hülsen geleichzeitig zu dem Greifer und/oder dem Endlosförderer bewegt werden.The conveyor preferably has a slide, which is movable between a receiving position in which a sleeve from above into a receptacle in front of the slider, and a front end position, on which a sleeve is displaced in the longitudinal direction of the receptacle. In this case, a plurality of sleeves can be arranged in a magazine above the receptacle, which are then inserted one after the other into the receptacle when it has been emptied via the slide. One or more sleeves can then be moved at the same time to the gripper and / or the endless conveyor via the slide.
Der Greifer weist vorzugsweise mehrere Backen auf, mittels denen eine Hülse dem Endlosförderer übergeben wird. Der Greifer kann dabei eine positionsgenaue Anordnung der Hülse gewährleisten, die dann von dem Endlosförderer übernommen wird.The gripper preferably has a plurality of jaws, by means of which a sleeve is transferred to the endless conveyor. The gripper can ensure a positionally accurate arrangement of the sleeve, which is then taken over by the endless conveyor.

Eine Wickelmaschine 1 umfasst ein Maschinengestell 2, an dem eine oder mehrere Wickelwellen 3 vorgesehen sind, die zum Aufwickeln eines bahnförmigen Materials, beispielsweise Folien, Papier oder Textilstoffe, auf Hülsen dienen. Die Wickelvorrichtung kann entsprechend der eingesetzten Materialien ausgebildet sein.A winding machine 1 comprises a
Das Maschinengestell 2 umfasst eine erste Kammer 4, an der die Wickelwellen 3 in einer ersten Position angeordnet werden können, und eine zweite Kammer 5, die in axiale Richtung der Wickelwellen 3 benachbart angeordnet ist und in die die Wickelwellen 3 verfahren werden können, um Hülsen aufzunehmen. Es ist alternativ auch möglich, die Wickelwellen 3 in axiale Richtung starr anzuordnen und die Hülsen mit einem Endlosförderer zu verfahren.The
Oberhalb der zweiten Kammer 5 ist ein Endlosförderer 6 zum Positionieren von Hülsen vorgesehen, wobei einzelne Hülsen 9 über einen Greifer 7 an den Endlosförderer 6 übergeben werden. Vor dem Greifer 7 ist noch eine Fördereinrichtung 8 zum Fördern einzelner Hülsen zu dem Greifer 7 angeordnet.Above the

Zwei der umlaufenden Bänder 11 sind an einem ersten Arm 17 gehalten, während zwei weitere Bänder 11 an einem zweiten Arm 18 gehalten sind. Die Arme 17 und 18 sind in horizontale Richtung verfahrbar oder verschwenkbar, wie dies durch die Pfeile angedeutet ist. In dem dargestellten Ausführungsbeispiel werden die Arme 17 und 18 über Zahnstangen 19 und 20 verfahren, die über ein Ritzel 21 bewegbar sind, das über eine Koppelwelle 22 angetrieben ist. Die Koppelwelle 22 kann durch einen Motor 16 gedreht werden, um die Arme 17 auseinander oder zueinander zu bewegen. Statt einen linearen Verfahren der Arme 17 und 18 kann auch ein Schwenkmechanismus vorgesehen sein, um die Bänder 11 von der Hülse 9 entfernen oder zur Aufnahme von Hülsen 9 zusammenzubewegen.Two of the circulating

Bei der Vorrichtung zum Positionieren von Hülsen 9 auf einer Wickelwelle 3 werden zunächst die Hülsen 9 einer Aufnahme vor dem Schieber 40 zugeführt, der dann die Hülsen 9 zu dem Greifer 7 verschiebt. An dem Greifer 7 wird über einen optischen Sensor, insbesondere eine Lichtschranke im Bereich des Kanals aus Bürsten 32, eine Positionserfassung vorgenommen, um die vordere Kante einer Hülse 9 zu erfassen. Anschließend wird die vorderste Hülse 9 den Backen 30 zugeführt, die dann die Hülse 9 dem Endlosförderer 6 zuführen, wobei die Backen 30 ein vorderes Ende der Hülse 9 in die durch die Bänder 11 gebildete Aufnahme einschieben. Der Endlosförderer 6 greift dann über die Bänder 11 die Hülse 9 und verfährt diese in axiale Richtung. Die nachfolgende Hülse 9 kann nun nach einer Positionserfassung wieder mit den Backen 30 gegriffen werden und in den Endlosförderer 6 eingeführt werden, wobei über die Positionserfassung ein Spalt zwischen zwei benachbarten Hülsen 9 einstellbar ist. Je nach dem aufzuwickelnden Material kann ein kleinerer oder größerer Spalt zwischen den Hülsen 9 vorgesehen werden. Dieser Vorgang wird solange wieder holt, bis der Endlosförderer 6 mit der gewünschten Anzahl an leeren Hülsen 9 bestückt ist.In the apparatus for
Anschließend wird der Endlosförderer 6 mit den Bändern 11 nach unten in der Kammer 5 verfahren, wofür ein entsprechender Antrieb an dem Gestell 2 vorgesehen ist. Sobald der Endlosförderer 6 in der gewünschten Position ist, kann nun eine Wickelwelle 3 in axiale Richtung in die Hülsen 9 eingesteckt werden. Wenn die Wickelwelle 3 innerhalb der Hülsen angeordnet ist, kann ein Spannfutter an der Wickelwelle 3 aktiviert werden, so dass die Hülsen 9 nun an der Wickelwelle 3 fixiert sind. Wenn die Übergabe an die Wickelwelle 3 stattgefunden hat, können die Arme 17 und 18 auseinander gefahren werden, so dass die Bänder 11 des Endlosförderers 6 von den Hülsen 9 weg bewegt werden. Wenn die Arme 17 und 18 auseinander bewegt wurden, kann der Endlosförderer 6 wieder nach oben bewegt werden, wobei die Arme 17 und 18 wieder geschlossen werden, damit weitere Hülsen 9 an dem Endlosförderer 6 aufgenommen werden können. Die auf der Wickelwelle 3 angeordneten Hülsen 9 können nun mit einem bandförmigen Material bewickelt zu werden.Subsequently, the
Mit der dargestellten Vorrichtung zum Positionieren von Hülsen 9 können Hülsen 9 unterschiedlicher Länge verarbeitet werden. Es kann dabei sinnvoll sein, mehrere Sensoren zur Erfassung der Position einer Hülse 9 vorzugsehen, beispielsweise um eine Vorderkante und eine Hinterkante der Hülse 9 zu erfassen, um Toleranzen bei der Länge einer Hülse 9 besser verarbeiten zu können.With the illustrated device for positioning
In dem dargestellten Ausführungsbeispiel werden die Backen 30 abhängig von der Position der Hülsen 9 gesteuert, so dass ein vorbestimmter Abstand zwischen zwei benachbarten Hülsen 9 eingestellt werden kann. Es ist natürlich auch möglich, die Hülsen 9 über den Schieber 40 direkt in den Endlosförderer 6 einzuschieben, wobei dann die Bewegung des Schiebers 40 abhängig von der Position einer vordersten Hülse 9 bewegt wird.In the illustrated embodiment, the
Die Bänder 11 des Endlosförderers 6 können sich mit gleichmäßiger Geschwindigkeit bewegen, aber es ist auch möglich, die Geschwindigkeit der Bänder 11 abhängig von der erfassen Position einer Hülse 9 zu steuern. Dann erfolgt die Anpassung eines Spaltes zwischen zwei Hülsen 9 nicht über einen Schieber 40 oder die Backen 30, sondern über die Steuerung der Geschwindigkeit der Bänder 11.The
Die dargestellten Hülsen 9 können aus Pappe oder einem anderen geeignetem Werkstoff hergestellt sein, je nachdem, welches Material auf die Hülsen 9 aufgewickelt werden soll.The illustrated
