Definitions
- the invention relates to a winding device for winding yarn on a directly driven bobbin tube, wherein a drive shaft and at least two power transmission bodies are present and the power transmission bodies are moved during driving of the drive shaft so that the bobbin tube is fixed against movement in the circumferential direction relative to the drive shaft.
- Bobbin sleeves are usually stored for winding the yarn between two bobbin plates or mounted on a bobbin in a creel.
- the drive of the coils can be done directly on the reel plate or on the reel mandrel or indirectly via a pressure roller. In this indirect drive mode, the pressure roller is driven and takes the coil with frictional engagement. Otherwise, one speaks of a direct drive of the coil or the bobbin, even if additional power transmission body transmit the torque from the drive to the bobbin.
- the direct drive of the coils requires, especially when winding precision windings, over the entire coil travel an accurate centering of the bobbin tubes and in particular a slip-free torque transmission between the bobbin tube and the drive shaft or the drive device.
- torque transmission errors occur, they promote both a faulty coil design and a faulty coil shape, and thus the quality of the coil. This can lead to process faults in the following processes.
- a chuck in winding machines for receiving a bobbin known, comprising a rotatable mandrel, a jacket with openings for the radial passage of each clamping element, a plurality of clamping elements, arranged in the space between mandrel and shell thrust elements for moving the clamping elements and a part of a device for Has moving the pushers.
- the clamping elements are provided with wedge-shaped surfaces in the axial direction. Along these surfaces they are axially displaced on corresponding mating surfaces of the thrust elements and thus simultaneously moved radially. It is tensioned by a device for moving the pusher elements with springs, which act on the pusher elements and are compressed by compressed air for relaxation.
- the DE 2 106 493 A1 discloses a sleeve chuck for winding shafts on Fadenholzspulvortechnischen using the freewheeling principle.
- This sleeve chuck has a central and a concentrically surrounded part, wherein one of the parts is driven and the other drives. Distributed over the circumference, a number of axially parallel extending roller body is provided between the two parts. The reel body are taken by the driving part in the circumferential direction, thereby wedged in between the driving and driven part in the direction of the former narrowing gap and thus make a positive connection between the driving and the driven part.
- the winding shaft that is, the drive shaft
- the roller bodies serve as a power transmission body.
- the winding shaft concentric with a provided with recesses for the reel body basket, which prevents the outward migration of the reel body, in particular when changing the sleeve.
- the CH 418 923 discloses a device for winding textile threads, which has a driving clutch, which operates similar to the freewheeling principle.
- a driving clutch which operates similar to the freewheeling principle.
- balls, rollers or pivotally hinged plates are pressed by centrifugal forces against the inner wall of the bobbin tube and thus transmit the torque from the spindle to the sleeve.
- the disadvantage is that the function is guaranteed only at very high speeds.
- the sleeve can also be held between two bobbin plates.
- a coil plate is in the DE 199 17 242 A1 disclosed.
- the bobbin plate has a centering shoulder, which only slightly engages in the interior of the bobbin tube in comparison to a bobbin mandrel.
- the bobbin plate has an end-side contact surface and there is an elastically resilient clamping ring between this contact surface and the end face of the sleeve, which exerts a force on the bobbin tube in the axial direction.
- the bobbin on a winding roller, which drives the bobbin tube. In a direct drive of the bobbin tube, however, no reliably slip-free drive can be realized with the device described.
- the bobbin tube is held between two bobbin plates.
- a reel plate is coupled to the drive shaft and the at least two power transmission bodies are designed as clamping claws and are movably connected via exactly two joints with the drive shaft and the reel disc and one of the two joints is formed from a bolt which is mounted in a slot.
- the clamping claws act as a lever which converts a torque of the drive shaft in a force component in the radial direction of the bobbin tube, whereby the sleeve is fixed relative to the bobbin plate.
- the design of the power transmission body as Spannpratzen allows a flat design and thus easy integration into the coil plate.
- the centering shoulder can be made correspondingly flat and engages only slightly into the sleeve interior, whereby the interchangeability of the sleeve or the full coil is facilitated. Due to the formation of joints of a combination of bolt and slot only two joints per clamps are required.
- the position of the clamping claws is changed by turning the drive shaft so that the sleeve is automatically fixed.
- the introduction and transmission of the torque is slip-free and without additional energy.
- the realization with clamping claws and joints is structurally simple.
- the sleeve fixation can be easily unlocked during doffing by gently turning the respective coil plate without further intervention.
- the winding device according to the invention is easy to use, reliable and inexpensive.

- the second joint of the clamping claws is formed from a second bolt, which penetrates a hole in the clamping claw and is firmly connected to the reel plate.
- the bore of the first joint is formed in the coil plate as a slot.
- the bolt of the joint and thus the Spannpratzen the necessary freedom of movement is given to securely fix the sleeve. At the same time the movement is limited, thus avoiding damage to the sleeve.

Description
Die Erfindung betrifft eine Spuleinrichtung zum Wickeln von Garn auf eine direkt angetriebene Spulenhülse, wobei eine Antriebswelle und mindestens zwei Kraftübertragungskörper vorhanden sind und die Kraftübertragungskörper beim Antreiben der Antriebswelle so bewegt werden, dass die Spulenhülse gegen eine Bewegung in Umfangsrichtung relativ zur Antriebswelle fixiert wird.The invention relates to a winding device for winding yarn on a directly driven bobbin tube, wherein a drive shaft and at least two power transmission bodies are present and the power transmission bodies are moved during driving of the drive shaft so that the bobbin tube is fixed against movement in the circumferential direction relative to the drive shaft.
Spulenhülsen werden üblicherweise zum Wickeln des Garnes zwischen zwei Spulentellern oder auf einem Spulendorn gelagert in einem Spulenrahmen aufgenommen. Der Antrieb der Spulen kann direkt über den Spulenteller beziehungsweise über den Spulendorn oder indirekt über eine Andrückwalze erfolgen. Bei dieser indirekten Antriebsweise wird die Andrückwalze angetrieben und nimmt die Spule über Reibschluss mit. Ansonsten spricht man von einem direkten Antrieb der Spule beziehungsweise der Spulenhülse, auch dann, wenn zusätzliche Kraftübertragungskörper das Drehmoment vom Antrieb auf die Spulenhülse übertragen.Bobbin sleeves are usually stored for winding the yarn between two bobbin plates or mounted on a bobbin in a creel. The drive of the coils can be done directly on the reel plate or on the reel mandrel or indirectly via a pressure roller. In this indirect drive mode, the pressure roller is driven and takes the coil with frictional engagement. Otherwise, one speaks of a direct drive of the coil or the bobbin, even if additional power transmission body transmit the torque from the drive to the bobbin.
Der direkte Antrieb der Spulen erfordert, insbesondere beim Wickeln von Präzisionswicklungen, über die ganze Spulenreise eine genaue Zentrierung der Spulenhülsen und insbesondere eine schlupflose Drehmomentübertragung zwischen der Spulenhülse und der Antriebswelle beziehungsweise der Antriebseinrichtung. Wenn Fehler bei der Drehmomentübertragung auftreten, begünstigen sie sowohl einen fehlerhaften Spulenaufbau als auch eine fehlerhafte Spulenform und damit die Qualität der Spule. Dies kann in den nachfolgenden Prozessen zu Prozessstörungen führen.The direct drive of the coils requires, especially when winding precision windings, over the entire coil travel an accurate centering of the bobbin tubes and in particular a slip-free torque transmission between the bobbin tube and the drive shaft or the drive device. When torque transmission errors occur, they promote both a faulty coil design and a faulty coil shape, and thus the quality of the coil. This can lead to process faults in the following processes.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Spuleinrichtung zu schaffen, bei der die Spulenhülse direkt angetrieben, auf einfache Weise eine schlupffreie Drehmomentüberragung von der Antriebswelle auf die Spulenhülse garantiert und der Hülsenwechsel einfach durchgeführt werden kann.It is therefore an object of the present invention to provide a winding device in which the bobbin tube driven directly, guaranteed in a simple manner a slip-free torque transfer from the drive shaft to the bobbin and the sleeve replacement can be easily performed.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by the characterizing features of
Zur Lösung der Aufgabe wird die Spulenhülse zwischen zwei Spulentellern gehalten. Ein Spulenteller ist mit der Antriebswelle gekoppelt und die mindestens zwei Kraftübertragungskörper sind als Spannpratzen ausgebildet und sind jeweils über genau zwei Gelenke mit der Antriebswelle und dem Spulenteller beweglich verbunden und eines der zwei Gelenke wird aus einem Bolzen gebildet, der in einem Langloch gelagert ist. Die Spannpratzen fungieren als Hebel, der ein Drehmoment der Antriebswelle in eine Kraftkomponente in radialer Richtung auf die Spulenhülse umwandelt, wodurch die Hülse gegenüber dem Spulenteller fixiert wird.To solve the problem, the bobbin tube is held between two bobbin plates. A reel plate is coupled to the drive shaft and the at least two power transmission bodies are designed as clamping claws and are movably connected via exactly two joints with the drive shaft and the reel disc and one of the two joints is formed from a bolt which is mounted in a slot. The clamping claws act as a lever which converts a torque of the drive shaft in a force component in the radial direction of the bobbin tube, whereby the sleeve is fixed relative to the bobbin plate.
Die Ausbildung der Kraftübertragungskörper als Spannpratzen ermöglicht eine flache Bauweise und damit eine leichte Integration in den Spulenteller. Die Zentrierschulter kann entsprechend flach ausgeführt werden und greift nur wenig in das Hülseninnere ein, wodurch die Auswechselbarkeit der Hülse beziehungsweise der vollen Spule erleichtert wird. Durch die Ausbildung von Gelenken aus einer Kombination von Bolzen und Langloch sind nur zwei Gelenke pro Spannpratzen erforderlich. Beim Anfahren der Spuleinrichtung wird durch Verdrehen der Antriebswelle die Position der Spannpratzen so verändert, dass die Hülse automatisch fixiert wird. Die Einleitung und Übertragung des Drehmomentes erfolgt schlupffrei und ohne Zusatzenergie. Die Realisierung mit Spannpratzen und Gelenken ist konstruktiv einfach. Die Hülsenfixierung lässt sich beim Doffen durch leichtes Verdrehen des betreffenden Spulentellers ohne weitere Eingriffe einfach entriegeln. Die erfindungsgemäße Spulvorrichtung ist einfach in der Bedienung, funktionssicher und kostengünstig.The design of the power transmission body as Spannpratzen allows a flat design and thus easy integration into the coil plate. The centering shoulder can be made correspondingly flat and engages only slightly into the sleeve interior, whereby the interchangeability of the sleeve or the full coil is facilitated. Due to the formation of joints of a combination of bolt and slot only two joints per clamps are required. When starting the winding device, the position of the clamping claws is changed by turning the drive shaft so that the sleeve is automatically fixed. The introduction and transmission of the torque is slip-free and without additional energy. The realization with clamping claws and joints is structurally simple. The sleeve fixation can be easily unlocked during doffing by gently turning the respective coil plate without further intervention. The winding device according to the invention is easy to use, reliable and inexpensive.
Gemäß einer bevorzugten Ausführungsform wird das erste Gelenk der Spannpratzen aus einem Bolzen gebildet, der in Bohrungen in der Spannpratze und dem Spulenteller gelagert und fest mit der Antriebswelle verbunden ist. Das zweite Gelenk der Spannpratzen wird aus einem zweiten Bolzen gebildet, der eine Bohrung in der Spannpratze durchdringt und fest mit dem Spulenteller verbunden ist. Die Gelenke werden nur beim Anfahren und Wechseln der Hülse betätigt und sind keiner Dauerbelastung durch Bewegung ausgesetzt. Die beschriebene einfache Ausführung erfüllt damit in ausreichender Weise die Anforderungen.According to a preferred embodiment, the first joint of the clamping claws is formed from a bolt which is mounted in bores in the clamping claw and the coil plate and fixedly connected to the drive shaft. The second joint of the clamping claws is formed from a second bolt, which penetrates a hole in the clamping claw and is firmly connected to the reel plate. The joints are actuated only when starting and changing the sleeve and are not exposed to continuous load by movement. The described simple embodiment thus satisfies the requirements in a sufficient manner.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist die Bohrung des ersten Gelenkes im Spulenteller als Langloch ausgebildet. Durch das Langloch wird dem Bolzen des Gelenkes und damit dem Spannpratzen die nötige Bewegungsfreiheit gegeben, um die Hülse sicher zu fixieren. Gleichzeitig wird die Bewegung begrenzt und damit eine Beschädigung der Hülse vermieden. Das Antriebsmoment kann zuverlässig auf die Hülse übertragen werden. Vorzugweise ist die dem ersten oder dem zweiten Gelenk zugeordnete Bohrung in der Spannpratze zusätzlich als Langloch ausgebildet, um die Abstandsänderung der Gelenke durch das Langloch im Spulenteller auszugleichen.According to a preferred embodiment of the invention, the bore of the first joint is formed in the coil plate as a slot. Through the slot the bolt of the joint and thus the Spannpratzen the necessary freedom of movement is given to securely fix the sleeve. At the same time the movement is limited, thus avoiding damage to the sleeve. The drive torque can be reliably transmitted to the sleeve. Preferably, the first or the second joint associated hole in the clamping claw is additionally as a slot designed to compensate for the change in distance of the joints through the slot in the coil plate.
Die Spannpratzen können aus einem Metall, wie zum Beispiel Stahl oder Aluminium, einem Kunststoff, einem Verbundwerkstoff oder einem elastischen Material, wie zum Beispiel Gummi, gefertigt werden.The clamping claws can be made of a metal, such as steel or aluminum, a plastic, a composite material or an elastic material, such as rubber.
Es ist denkbar, dass die Spannpratze eine Oberflächenform aufweist, die genau in eine entsprechende Form an der Hülse eingreift. Dazu muss jedoch eine individuell angepasste Hülse verwendet werden und zur Fixierung ist eine bestimmte Winkelstellung erforderlich. Deshalb ist die Spulenhülse zur Fixierung gegen eine Bewegung in Umfangsrichtung relativ zum Spulenteller vorteilhafterweise mittels der Spannpratzen klemmbar. So können beliebige Hülsen verwendet werden und eine spezielle Winkelstellung muss nicht beachtet werden.It is conceivable that the clamping claw has a surface shape which engages exactly in a corresponding shape on the sleeve. For this, however, an individually adapted sleeve must be used and for fixing a certain angular position is required. Therefore, the bobbin sleeve for fixing against movement in the circumferential direction relative to the bobbin plate advantageously by means of the clamping claws clamped. So any sleeves can be used and a special angular position must be disregarded.
Gemäß einer Weiterbildung dieser vorteilhaften Ausführungsform ist die die Spulenhülse klemmende Oberfläche der Spannpratzen in ihrer Beschaffenheit an die zu klemmende Hülse angepasst. Die die Spulenhülse klemmende Oberfläche kann dazu eine definierte Rauhigkeit aufweisen, mit Rändeln versehen sein, galvanisch beschichtet sein, mit aufgebrachten elastischen Materialien versehen sein oder mit Gummischuhen überzogen sein.According to a development of this advantageous embodiment, the bobbin clamping surface of the clamping claws is adapted in their nature to the sleeve to be clamped. For this purpose, the surface clamping the bobbin tube may have a defined roughness, be provided with knurling, be galvanically coated, be provided with applied elastic materials or be coated with rubber shoes.
Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Spuleinrichtung sind die Spannpratzen so ausgebildet, dass zusätzlich die Spulenhülse gegenüber dem Spulenteller fixiert wird, wenn die Antriebswelle abgebremst wird. Damit ist auch ein schlupffreies und definiertes Abbremsen möglich. Dazu können die Spannpratzen jeweils zwei Oberflächenbereiche aufweisen, wobei der eine Oberflächenbereich die Spulenhülse beim Antreiben und der andere Oberflächenbereich die Spulenhülse beim Abbremsen der Antriebswelle klemmt.According to a preferred embodiment of the winding device according to the invention, the clamping claws are formed so that in addition the bobbin tube is fixed relative to the bobbin plate when the drive shaft is braked. Thus, a slip-free and defined braking is possible. For this purpose, the clamping claws each have two surface areas, wherein the one surface area, the bobbin tube when driving and the other surface area clamps the bobbin when braking the drive shaft.
Die Fixierung der Spulenhülse kann mit zwei Spannpratzen erfolgen. Vorteilhafterweise werden jedoch drei Spannpratzen verwendet, da so eine bessere Zentrierung der Hülse erfolgen kann. Mehr als drei Spannpratzen sind prinzipiell möglich.The fixation of the bobbin tube can be done with two clamps. Advantageously, however, three clamping claws are used, as can be done so a better centering of the sleeve. More than three clamping claws are possible in principle.
Die Zentrierung der Hülse, insbesondere bei unterschiedlichen Hülseninnendurchmessern, kann verbessert werden, wenn der Spulenteller an der der Innenseite der Spulenhülse zugewandten Seite ein elastisches Element aufweist. Das elastische Element kann dabei als Ring, zum Beispiel als O-Ring, Quaderring oder Keilring, ausgebildet sein.The centering of the sleeve, in particular with different sleeve inner diameters, can be improved if the coil plate has an elastic element on the side facing the inside of the coil sleeve. The elastic element may be formed as a ring, for example as an O-ring, square ring or wedge ring.
