Furthermore, the invention relates to a yarn winder, a yarn winder assembly and a method for handling a yarn package.

STATE OF THE ART

Technical yarns of the type described above are wound with Garnspulmaschinen to yarn packages. The yarn winding machines can have only one winding station or several winding stations on which yarn bobbins can be wound in parallel. In the area of a winding station, the yarn winding machine has a spindle driven by a rotary drive. For winding a yarn package, a sleeve is first applied to the spindle. The yarn is then fed to the winding station. After catching the yarn, a winding is created on the sleeve. After completion of the yarn package formed with sleeve and winding, the yarn package is removed from the Garnspulmaschine by the yarn package is removed in the axial direction of the spindle. The yarn package is then transported and in particular further processing, in which, for example, the yarn is unwound, or a storage device for the purpose of stocking the yarn packages supplied. Basically, there is a need for yarn packages on which as much yarn is wound, but an increase in the absorption capacity of a yarn package due to the then also increasing mass of the winding limits are set.

US 1,405,554 discloses a rack for coils by means of which tangling of a thread during unwinding is to be avoided. The frame has plate-shaped side walls. Between the side walls extending on the one hand several handrails for coils with a thread and on the other hand holding rods for crochet balls. The frame is used to hold the coil stationary thereon, which may also be the case during unwinding of the chord.

US 4,921,185 discloses a rack for a spool for a yarn for knitting or crocheting. The frame is formed with two x-shaped, hinged together rods, one of the rods in the upper end region forms a half-shell-shaped receptacle for a telescopic shaft on which there is a winding of the yarn. Again, the frame is used to hold the coil stationary, which may also be the case during unwinding of the chord.

The publication DE 100 36 861 A1 discloses a winding machine in which rotatably driven spindles are mounted on a revolver. The spindles have rotatable chucks, by means of which on each spindle several successively lined up sleeves can be clamped. The chuck is mounted in one end area on the machine frame. Additional storage of the chuck takes place on the opposite side of the chuck via an additional support means, which is brought into engagement with the chuck in a winding position of the revolver. For this purpose, the support means comprises a carriage, with which the support means along two orthogonally oriented axes, which lie in a plane which is oriented vertically to the longitudinal axis of the spindle, is movable.

The publication WO 2007/083162 describes the winding of bobbins on a spindle of a winder, the removal of the finished wound bobbin from the spindle of the winder, the transport of the bobbin by means of a transport device to a warehouse, the removal of the bobbin from the transport device via a pivotable holder and the storage of the bobbin by means of a frame which has a horizontal spindle. After storage (possibly over several months), the coil is again removed from the frame and in turn transported via the transport device, now to a frame, from which then the Spulgut is removed for further processing. Here, the Spulgut to be unwound from the spool by pulling on the Spulgut. On a rack, a plurality of rows and columns of coils may be arranged. As is known here is described that the racks are designed for several coils as a transport vehicle, whereby an exchange of the coils to be accelerated. The holding device of the frame in this case already has a guide device for the Spulgut. WO 2007/083162 proposes a transport vehicle for a spool, the fixedly interconnected frame struts extending along the edges of a cube, wherein a vertical edge and the adjacent two upper horizontal edges of the cube are not equipped with edge struts. On an additional, attached to the edge struts vertical strut a rotatable spindle is mounted, on which the coil is supported. The frame struts are supported by wheels movable against the ground. The spindle protrudes freely from the vertical strut. The spindle also extends on the side facing away from the coil with a free end portion of the vertical strut out. At this free end a gear is attached. Is supported on the spindle, a coil, the frame can be moved on the one hand on the rollers, while on the other hand, it is possible that a transport of Coil takes place, in which the fork of a forklift engages under the underside of the frame. For the storage of the coil, the frame can be arranged in a coil frame, which has a rotary member and a yarn guide device. Here, several coils are arranged like a grid on the coil frame. The rotary member of the coil frame is formed with a gear which engages in the gear of the spindle. About a braking device, a braking force can be applied to the gear. After winding the bobbin on a winder, the bobbin is removed from the winder and pushed onto the spindle of the transport vehicle. On the transport vehicle, the coil is then fed to the coil frame. With the application of a tensile force on the Spulgut the release of the braking device, which unwinding of the coil is possible. A reduction in the tensile force leads to the operation of the braking device and thus reducing the speed of the coil. Alternatively, it is proposed that during the unwinding of the Spulguts a drive of the spindle of the transport vehicle can be done via an electric motor. In an alternative embodiment, the transport vehicle may be formed only with a bottom frame and thereof cantilevered vertical rods on which then rotatably the spindle is held.

US 2012/0286083 A1 also discloses a caddy for a spool. This has frontal hexagonal frame members, on each of which a vertical strut is supported, on which the coil can be rotatably mounted. The caddy has wheels that allow it to be moved with the spool between different locations. The front-side frame members have a receiving device, by means of which it is possible to receive a coil, through which a shaft projecting end and which rests with its lateral surface on the ground, by rolling movement of the transport frame. After such reception of the coil, the coil is rotatably mounted on the transport frame.

State of the art for the operation of a winder can DE 10 2011 052 699 A1 be removed.

DE 41 25 310 A1 discloses a winder in which an endless synthetic yarn is withdrawn from a conveyor via a thread guide from a supply. The yarn is guided over a heating rail, cooled again by means of a cooling rail, curled by means of a crimping device and then conveyed via a conveyor Supplied by means of which then the yarn is wound as a cross winding on a spool. The drive of the coil via a driven by an electric motor drive roller, which is pressed against the lateral surface of the winding of the coil. The type of storage of the coil is in DE 41 25 310 A1 not described in detail.

DE 1 949 423 A1 also describes a method for winding a yarn on a spool with the drive of the spool via a nip roll. Here, however, the pressure roller is pressed against a flange of the coil.

Also according to the document JP S60 242155 A In the region of end flanges, a coil is in rolling contact with four rollers distributed over the circumference of the flanges and pressed against the flanges.

The pamphlets US 5,836,536 A . WO 81/02882 A1 and WO 2013/187964 A1 relate to a non-generic technology field, namely cable drums.

DESCRIPTION OF THE INVENTION

• Damit in einer herkömmlichen Garnspulmaschine eine Hülse auf die Spindel aufschiebbar ist und nach Beendigung des Wickelvorgangs die Garnspule mit der Hülse von der Spindel entnehmbar ist, kragt für eine mögliche Ausführungsform einer Garnspulmaschine die Spindel frei von einem Rahmen der Garnspulmaschine aus mit "fliegender Lagerung" der Spindel. Mit Vergrößerung der Masse der Garnspule kommt es zu einer erhöhten Beanspruchung der Lager der Spindel, wobei die Lager u. U. noch mit einem Spalt beabstandet von der dem Rahmen zugewandten Stirnseite der Garnspule angeordnet sind, womit sich die ohnehin hohen Beanspruchungen der Lager infolge der fliegenden Lagerung noch weiter erhöhen. Somit erfordert die Vergrößerung der Masse der Garnspule eine größere Dimensionierung der Lager, was zu Bauraumproblemen führen kann.
• Des Weiteren führt eine Vergrößerung der Masse der Garnspule zu einer vergrößerten Biegebeanspruchung der frei auskragenden Spindel. Kommt es infolge der vergrößerten Biegebeanspruchung zu einer Durchbiegung der Spindel, führt dies zur Verringerung der Präzision des Spulprozesses und Abweichungen des herbeigeführten Spulbildes von dem vorgegebenen Spulbild. Der vergrößerten Biegebeanspruchung muss u. U. durch ein vergrößertes Flächenträgheitsmoment der Spindel, also insbesondere einem vergrößerten Durchmesser der Spindel, Rechnung getragen werden, was die Bauraumproblematik weiter verschärft.
• Mit Erhöhung der Masse der Garnspule wird die Entnahme der Garnspule von der Spindel erschwert, da sich die Entnahmekräfte erhöhen. Bei der Entnahme der Garnspule ist ein Einwirken auf die Wicklung zu vermeiden, da eine Einwirkung auf die Wicklung zur Störung des Spulbildes und schlimmstenfalls zur Beschädigung des Garns führen kann. Somit fällt die Wicklung für die Aufbringung der erforderlichen Entnahmekräften weg.
  Durch die Hülse der Garnspule erstreckt sich nach dem Fertigstellen der Wicklung die Spindel, so dass auch von innen auf die Garnspule keine Entnahmekräfte aufgebracht werden können.
  Somit muss in der Regel die Entnahme der Garnspule von der Spindel, welche üblicherweise durch Aufschieben auf einen Dorn einer Transporteinrichtung erfolgt, durch alleiniges Einwirken auf ein frei herauskragendes Ende der Hülse bewerkstelligt werden, was aber für eine große Masse der Garnspule nicht ausreichend sein kann.
• Entsprechende Probleme ergeben sich bei Garnspulmaschinen, bei welchen die Hülse der Garnspule während des Spulvorganges in beiden Endbereich eines Lagerzapfens gehalten ist, die Entnahme erfordert hier zunächst eine Beseitigung eines Lagerzapfens, damit das Innere der Hülse von dieser Seite zugänglich gemacht wird. Mit einem beseitigtem Lagerzapfen stützt sich die fertig gewickelte Garnspule aber mit dem ganzen Gewicht nur auf dem einen verbleibenden Lagerzapfen ab, dessen Lagerung somit entsprechend zu dimensionieren ist.
• Probleme bereitet eine große Masse der Wicklung auch während eines Transports und einer Bevorratung oder Lagerung der Garnspule: Die hohe Masse der Garnspule kann bereits bei horizontaler Ausrichtung der Garnspulenachse zu einem "Durchhängen" der Wicklung infolge der Gravitationskräfte führen, was zu einer unerwünschten Unrundheit der Wicklung führt und zu Spannungen und unerwünschten Dehnungen im Garn führen kann.
  Bei einer Verschwenkung der Garnspule während des Transports entstehen durch die hohe Masse der Wicklung dynamische Kräfte, welche schlimmstenfalls das Spulbild beeinträchtigen.
  Muss während des Transports oder der Bevorratung die Garnspule auf ihrer Mantelfläche abgelegt werden, kommt es mit zunehmendem Gewicht der Garnspule zu sich vergrößernden Flächenpressungen im Auflagebereich der Wicklung, welche zu Beschädigungen des Garns führen können.

The present invention is based initially on an analysis of the reasons why, for conventional yarn packages, the mass of the winding is limited:

• Thus, in a conventional Garnspulmaschine a sleeve is pushed onto the spindle and after completion of the winding process, the yarn package with the sleeve is removable from the spindle, for a possible embodiment of a Garnspulmaschine the spindle protrudes freely from a frame of Garnspulmaschine with "flying storage" of Spindle. With increasing the mass of the yarn package there is an increased stress on the bearings of the spindle, the bearings u. U. still with a gap spaced from the frame facing the end face of the yarn package are arranged, which further increase the already high stress on the bearings due to the flying storage. Thus, the increase in the mass of the yarn package requires a larger dimension of the bearing, which can lead to space problems.
• Furthermore, an increase in the mass of the yarn package leads to an increased bending stress of the freely projecting spindle. If there is a deflection of the spindle as a result of the increased bending stress, this leads to a reduction in the precision of the winding process and deviations of the induced winding pattern from the given winding pattern. The increased bending stress must u. U. by an increased area moment of inertia of the spindle, so in particular an enlarged diameter of the spindle, be taken into account, which further aggravates the space problem.
• With increasing the mass of the yarn package, the removal of the yarn package from the spindle is made more difficult, since the extraction forces increase. When removing the yarn bobbin, it is important to avoid acting on the winding, as exposure to the winding may result in distortion of the winder and, in the worst case, damage to the yarn. Thus, the winding for the application of the required extraction forces falls away.
  Through the sleeve of the yarn package after completion of the winding, the spindle extends, so that no extraction forces can be applied from the inside to the yarn package.
  Thus, usually the removal of the yarn package from the spindle, which usually takes place by sliding on a mandrel of a transport device, be effected solely by acting on a freely projecting end of the sleeve, but this may not be sufficient for a large mass of the yarn package.
• Corresponding problems arise in Garnspulmaschinen in which the sleeve of the yarn package is held during the winding process in both end of a journal, the removal here requires first a disposal of a journal, so that the inside of the sleeve is made accessible from this page. With a removed journal, the finished wound bobbin but supported with the whole weight only on the one remaining bearing pin whose storage is thus to be dimensioned accordingly.
• A large mass of the winding also causes problems during transport and storage or storage of the yarn package. The high mass of the yarn package can already lead to a "sagging" of the winding as a result of the gravitational forces when the yarn package axis is oriented horizontally, which leads to undesirable runout of the winding leads and can lead to tensions and undesirable strains in the yarn.
  During a pivoting of the yarn package during transport caused by the high mass of the winding dynamic forces, which in the worst case affect the Spulbild.
  If the yarn bobbin has to be deposited on its lateral surface during transport or storage, as the weight of the yarn package increases, increasing surface pressures occur in the contact area of the winding, which can lead to damage to the yarn.

umfasst.For a solution to the problem underlying the invention, the use of a bobbin handling container for a yarn package for a technical yarn is proposed. The "handling", which can be done in the context of the invention by means of the yarn package handling container, consists in the winding of the yarn package. It is possible that the "handling" also the recording, storing and / or holding the bobbin during

• unwinding the yarn package,
• the removal of the yarn package from the spindle or yarn winder,
• the transport of the yarn package,
• a (Ab-) braking or locking the yarn package and / or
• the stocking of the yarn package

includes.

The bobbin handling container according to the invention for a yarn package has a frame or housing. Opposite the frame or housing, a spindle is rotatably mounted in (at least) one bearing. Preferably, said bearing is a circumferentially closed bearing in which the spindle is permanently received and which thus supports the spindle in all radial directions to the spindle axis relative to the frame or housing. The bearing may be formed as a plain bearing, but while a rolling bearing is preferably used. According to the invention, therefore, the spindle is not mounted on the Garnspulmaschine, but on the Garnspulen handling container. Here, the frame or the housing can be specifically adapted to the storage and acting on a large mass of the yarn package on the spindle stresses. Possibly, for the inventive design, the bearings can be arranged closer to a front side of the yarn package than is the case for the storage of the spindle on the Garnspulmaschine. Thus, according to the invention, the bearing stresses can be reduced, and it can u. U. a reduced bending stress of the spindle can be ensured. It is also possible even that the spindle is mounted on both sides of the yarn package on the frame or housing, whereby the unfavorable in terms of mechanical stress "flying storage" can be eliminated. However, the embodiment according to the invention is also advantageous in terms of handling the yarn package with the removal, during transport and storage: removal, holding and transport forces can be applied directly to the Garnspulen handling container, without removal, holding and transport forces the yarn package and any sleeve must be applied. During transport or storage, the bobbin handling container may be parked on the frame or housing. It is also possible that during storage of the bobbin handling container is arranged in a storage rack or an arrangement of several yarn package handling container side by side in series and / or stacking of several yarn bobbin handling containers one above the other he follows. It is also possible that a bobbin handling container is used several times, so that on this first a yarn package is wound, which then u. U. is handled at another location. Following this, the bobbin handling container can then be reused with the same spindle to wind a new bobbin on it, and so on.

For a generation of a drive movement for winding and / or unwinding of the yarn, there are many possibilities. For a particular proposal of the invention, the spindle has a spindle coupling element. The spindle coupling element is preferably arranged in an end region of the spindle projecting from the frame or housing. About the spindle coupling element, the spindle can be releasably connected to a Garnspulmaschinen coupling element of a rotary drive a Garnspulmaschine such that the transmission of a drive torque of the rotary drive to the spindle. It is entirely possible that such a spindle coupling element is not used exclusively during winding or unwinding of the yarn. Rather, the spindle coupling element can also be used for further handling of the yarn package. It is possible, for example, that transport forces are also applied to the bobbin handling container via the spindle coupling element. It is also possible that the spindle coupling element is used to rotate the yarn package in the yarn package handling container during storage, so that temporary acting in a circumferential region of the winding gravitational forces are displaced in the circumferential direction.

For the type of training of the rotationally fixed connection between the spindle coupling element and the Garnspulmaschinen coupling element, there are a variety of known to those skilled in the ways. Thus, the coupling elements frictionally or positively transfer the drive torque.

For example, the Garnspulmaschinen coupling element may be formed with a spline or a feather key of a drive pin of the rotary drive, while the spindle coupling element is formed with a spline inner profile or a keyway. Of course, any other form-fitting transmission cross sections of the spindle coupling element and the Garnspulmaschinen coupling element are possible.

• durch Erzeugung von axialen Anpresskräften zwischen Spindel-Kupplungselement und Garnspulmaschinen-Kupplungselement,
• u. U. auch mit einem Anpressen von zwei Kontakt-Kegeln aneinander, oder
• durch Ausbildung eines radialen Reibkontakts, beispielsweise mittels eines radial nach außen gespreizten Spreizdorns des Drehantriebs, welcher an eine hohlzylindrische Innenfläche des Spindel-Kupplungselements angepresst wird,

ausgebildet sein.A possible frictional connection can

• by generating axial contact forces between spindle coupling element and yarn winding machine coupling element,
• u. U. also with a pressing of two contact cones to each other, or
• by forming a radial friction contact, for example by means of a radially outwardly spread expanding mandrel of the rotary drive, which is pressed against a hollow cylindrical inner surface of the spindle coupling element,

be educated.

Here, the coupling between the spindle coupling element and the Garnspulmaschinen coupling element can be accomplished in any way. Preferably, this coupling takes place without the use of a tool, a screw u. Ä. For example, the positive or frictional clutch movement controlled with approach of the Garnspulen handling container and thus the spindle coupling element to the Garnspulmaschine and thus the Garnspulmaschinen coupling element. During this approach, the Garnspulmaschinen-coupling element can enter into an end-side recess of the spindle coupling element (or vice versa).

In principle, the frame or the housing can be configured as desired. In a further embodiment of the invention it is proposed that the frame or the housing has a supporting or holding area which serves for supporting or holding the yarn bobbin handling container on a yarn winder. By way of example, this may be a contact area formed by the frame or housing which rests on a footprint of the yarn winder. However, it is also possible for the holding of the bobbin handling container on the bobbin winding machine to take place in a lateral, upper and / or frontal holding region.

Alternatively or cumulatively, it is possible for the frame or housing to have a handling area for handling the bobbin handling container. This is, for example, a handling area, via which application forces, removal forces or transport forces can be applied to the bobbin handling container. For example, a handling area as a hook, eye, tab for a means of transport be educated. By way of non-limiting example, the bobbin handling container may also include a handling area in the form of a pickup shoe for the tines of a forklift truck.

Alternatively or cumulatively, it is possible that the frame or the housing of the yarn package handling container has a coupling region, in the region of which a coupling of the yarn package handling container with another yarn package handling container is possible. Here, the coupling can be done with a positive connection, a frictional connection or use of a coupling or fastening means. To mention only a non-limiting example, the coupling region may be formed with a projection or a recess, which engages or in which a form-fitting recess or a projection of an adjacent Garnspulen handling container. In this case, the coupling region is preferably designed suitably for a coupling of stacked yarn bobbin handling containers and / or adjacent bobbin handling containers.

Alternatively or cumulatively, it is possible that the frame or the housing has a guide unit. This guide unit can interact with the Garnspulmaschine to ensure the proper coupling of the spindle coupling element with the Garnspulmaschinen coupling element and / or the coaxial alignment of the spindle with the rotary drive of the Garnspulmaschine when approaching the Garnspulen handling container to the Garnspulmaschine. It is also possible that the Garnspulmaschine is formed with guide rails with which the guide unit of the Garnspulen handling container interacts in order to guide the approach of the Garnspulen handling container to the Garnspulmaschine.

The bobbin handling container can be designed as any one-piece or multi-part assembly, possibly with components screwed together, welded or otherwise interconnected. For a particular proposal of the invention, the yarn package handling container is formed with a plurality of releasably interconnected components. By replacing components then an adaptation of the yarn package handling container can be made to different requirements. To name just one example, a bobbin handling container may be used to adjust the length of the bobbin handling container and thus the possible longitudinal extent of the bobbin be formed with side panels or side struts of different lengths. Correspondingly, end portions of the bobbin handling container may also be provided in different sizes to permit conversion of the bobbin handling container for bobbins of different diameters. It is also possible for spindles of different lengths and / or diameters to be used in the bobbin handling container, depending on the yarn package to be wound. Individual adjustment measures for the side parts or side struts, the front side parts and the spindles may, depending on the yarn, Garnspulmaschine, winding process, Spulbild, inserted traversing mechanism, drive the yarn package u. Ä. Be made.

For a further yarn package handling container according to the invention, the housing or the frame is not formed closed in the circumferential direction. Rather, the housing or the frame has an opening. On the one hand, this opening can be used so that during the winding of the yarn, the yarn can enter the inside of the yarn package handling container and / or through this during yarn unwinding, the yarn can be led out of the interior of the yarn package handling container. It is also possible that in the area of the opening when using the yarn package handling container with a yarn winding machine, a traversing device, which is used for iridescent guiding of the yarn when laying on the spool, extends. For this purpose, the opening in a side region of the bobbin handling container is arranged with a minimum axial extent corresponding to the laying width of the yarn, which additionally extend the opening at least partially in the area of the Garnspulmaschine facing end side of the Garnspulen handling container. It is also possible that an opening extends continuously from a recess of the one end face of the yarn package handling container over the side region up to a recess of the other end side of the yarn package handling container. It is further possible that the opening is only temporarily open, in particular during winding and unwinding, while it is closable, in particular during transport and / or stocking, in order to prevent, for example, the entry of contaminants. In this case, the closure can be effected by a closure plate or flap or by a cover such as a tarpaulin or foil.

In the event that it should be ensured that during handling no unintentional unwinding of the yarn takes place, the invention proposes that in the Garnspulen handling container a braking device is present. In this context, a "braking device" in the sense of the invention includes both a frictional braking device and a positive-locking braking device, which may also be designed as a latching or locking device. The braking device acts between frame or housing and spindle or a possibly arranged on the spindle sleeve.

Preferably, the braking device is activated during transport of the yarn package handling container. But it is also possible that the braking device is used to make a deceleration of the yarn package at the end of the winding process.

The actuation of said brake device can be arbitrary. To name just a few non-limiting examples, the operation of the braking device can be done manually by the operator. Also possible is the operation of the braking device by an actuator, which may be controlled for example by a control device of the Garnspulmaschine and / or a control device of the Garnspulen handling container. It is also possible that the braking device is released under load, when a torque is applied to the spindle of the yarn winding machine, which exceeds a predetermined threshold torque which is greater than any acting during handling moments, which are responsible for unintentional unwinding of the yarn. For a particular proposal according to the invention, however, the braking device is actuated in a motion-controlled manner, "activation" being understood to mean activating the braking device and / or releasing the braking device. To name only a non-limiting example of such motion control of the braking device, the braking device may be activated, for example, by a spring for not coupled to the Garnspulmaschine Garnspulen handling container. With the approach of the yarn package handling container to the yarn winding machine (possibly also simultaneously with coupling of the spindle coupling element with the yarn winding machine coupling element), the braking device can then be automatically released by this approach, thus enabling a winding process. The same applies to an approach of the yarn package handling container to the yarn winder for ensuring unwinding. This embodiment has the advantage that with the removal of the bobbin handling container from the yarn winder or a device for unwinding the braking device is automatically operated, which is then also effective during transport and storage of the bobbin handling container. It is also possible that the movement-controlled actuation of the braking device with the installation of the yarn package handling container on the ground takes place, for example, in the area of the contact area with the setting up an actuating cam is actuated, which then activates or deactivates the braking device.

Compared to the frame or housing, the spindle can be mounted arbitrarily. So it is quite possible that the spindle is supported only on one side of the yarn package on the frame or housing (with any number and arrangement of the bearings on this side of the yarn package). In a further embodiment of the yarn bobbin handling container according to the invention, however, the spindle on the frame or housing on two sides of an axial portion of the spindle on which a yarn package can be arranged or is stored. To mention only a non-limiting example, a two-sided storage of the spindle in the two end regions of the spindle can be done on the front side parts of the frame or the housing. In the event that a plurality of yarn packages are mounted in a yarn package handling container on a spindle, a bearing of the spindle between adjacent axial sections for the yarn packages can be carried out.

In principle, a yarn bobbin handling container according to the invention can be used for yarn bobbins of any desired masses. Preferably, however, the yarn bobbin handling container according to the invention is designed such that it can be determined for handling bobbins with a mass of the winding of more than 300 kg, in particular more than 500 kg, more than 800 kg or more than 1000 kg.

Another solution to the problem underlying the invention is given by a yarn winding machine, in which a winding station is formed without a spindle. Such a yarn winding machine is particularly suitable for use with a yarn package handling container, as has been previously explained. Thus, the yarn winder uses the spindle of the yarn package handling container. The transmission of the drive movement of the Garnspulmaschine on the spindle of the Garnspulen handling container can then be done using the spindle coupling element and the Garnspulmaschinen coupling element. In this case, the winding of several bobbins on the same yarn winder with use of multiple bobbin handling container with each associated spindles takes place. On the other hand, the same traversing device (as well as possibly the same further devices as a capturing device, a control device, etc.) can be used for these multiple winding processes. a removal device, a drive unit, u. Ä.) Of the yarn winding machine can be used

Such a yarn winder preferably has a rotary drive. The rotary drive has in this case, for example in the frontal region of a drive pin, a Garnspulmaschinen coupling element. The Garnspulmaschinen coupling element is, as described above, with a spindle-coupling element of a spindle, preferably the Garnspulen handling container, connectable to transmit a drive torque, this connection is solvable, which is done for example without tools or (as described above) motion controlled can.

According to a further yarn winding machine according to the invention this has a support or holding area for supporting or holding a yarn bobbin handling container on the yarn winder and / or a guide unit for guiding a yarn bobbin handling container relative to the yarn winder. In principle, what has been said about the support or holding area or the guide unit of the bobbin handling container applies to the support or holding area or the guide unit. It is also possible, for example, that a guide unit of the Garnspulmaschine is formed with a kind of guided slide on which a Garnspulen handling container is placed, in particular under exact position specification by corresponding projections, centering or other centering, and then with which the Garnspulen handling container to the Garnspulmaschine and the drive pin of the rotary drive of the yarn winding machine can be approximated.

In the context of the invention, the Garnspulmaschine has laterally next to a traversing device on a free receiving space, in the region of which a bobbin handling container can be arranged in each case for a winding operation.

If a yarn bobbin handling container is to be used with the yarn winding machine, which has a braking device, the invention proposes that the yarn winding machine is equipped with a brake actuating device, by means of which the braking device of the yarn bobbin handling container can be actuated. If the braking device of the yarn package handling container, for example, actuated motion controlled, the brake actuator may be formed as an actuating pin, which approaches the approach Garnspulen handling container to the Garnspulmaschine a releasing or activating force on the braking device exerts.

In the event that a Garnspulmaschine is to be used for a Garnspulen handling container in which simultaneously several yarn packages can be wound, the invention proposes that in the Garnspulmaschine in a recessed receiving space for a Garnspulen handling container several traversing devices are arranged, each one of these traversing devices is responsible for winding a yarn package.

Preferably, the yarn winder is designed and intended for handling yarn packages having a mass of winding of more than 300 kg, in particular more than 500 kg or more than 800 kg. Here, the yarn package may have a drive and a control which ensures a constant feeding and winding speed of the yarn, regardless of the diameter of the winding, wherein the feeding and winding speed of the yarn is preferably greater than 40 m / min.

A further solution of the object underlying the invention is given by a Garnspulmaschinen assembly in which a Garnspulmaschine of the type described above, together with at least one Garnspulen handling container of the type described above is used.

• Bei diesem Verfahren erfolgt in einem ersten Verfahrensschritt eine Bereitstellung eines Garnspulen-Handhabungscontainers im Bereich der Garnspulmaschine.
• In einem weiteren Verfahrensschritt erfolgt die Kupplung des Spindel-Kupplungselements des Garnspulen-Handhabungscontainers mit dem Garnspulmaschinen-Kupplungselements zwecks Erzeugung einer antriebsfesten Verbindung, was bspw. bewegungsgesteuert erfolgen kann, wie dieses zuvor beschrieben worden ist.
• Im nächsten Verfahrensschritt erfolgt das Wickeln der Garnspule auf einer Spindel des Garnspulen-Handhabungscontainers.
• Ist die Garnspule fertig gewickelt, erfolgt das Lösen der Kupplung des Spindel-Kupplungselements des Garnspulen-Handhabungscontainers mit dem Garnspulmaschinen-Kupplungselement.
• Schließlich erfolgt der Abtransport des Garnspulen-Handhabungscontainers mit der darin gewickelten Garnspule von der Garnspulmaschine, beispielsweise zur weiteren Verarbeitung, zum Transport oder zur Bevorratung.

Another solution according to the invention relates to a method for handling a yarn package. Preferably, this is a yarn package with a mass of the winding of more than 300 kg, in particular more than 500 kg or more than 800 kg.

• In this method, in a first method step, provision is made of a yarn package handling container in the area of the yarn winder.
• In a further method step, the coupling of the spindle coupling element of the yarn package handling container with the Garnspulmaschinen coupling element for the purpose of generating a drive-fixed connection, which can be done. For example, motion-controlled, as has been previously described.
• In the next step of the process, the yarn package is wound on a spindle of the yarn package handling container.
• When the yarn package has been finished wound, the coupling of the spindle coupling element of the yarn package handling container is released with the yarn winding machine coupling element.
• Finally, the removal of the yarn package handling container with the yarn package wound therein is carried out by the yarn winding machine, for example for further processing, transport or storage.

It is entirely possible that the said method steps are also carried out in a changed sequence or simultaneously. Thus, for example, the production of the coupling of the spindle coupling element of the yarn package handling container with the Garnspulmaschinen coupling element can be carried out motion-controlled simultaneously with the provision of the Garnspulen handling container in the field of Garnspulmaschine. Accordingly, the solution of said coupling can take place during the removal of the yarn package handling container with the yarn package wound therein from the yarn winder.

During the mentioned process steps can u. U. supporting or holding areas, handling areas, coupling areas or guide units of the frame or the housing of the bobbin handling container and / or the Garnspulmaschine be used. During the approach between the yarn package handling container and the yarn winder, the yarn may be passed through an opening of the housing or frame of the yarn package handling container and / or a traversing device may enter such opening of the frame or housing of the yarn package handling container.

• bewegungsgesteuert mit der Bereitstellung des Garnspulen-Handhabungscontainers im Bereich der Garnspulmaschine,
• mit der Herstellung der Kupplung zwischen dem Spindel-Kupplungselement und dem Garnspulmaschinen-Kupplungselement,
• dem Beginn und/oder dem Ende des Wickelvorgangs der Garnspule,
• dem Lösen der Kupplung und/oder
• dem Abtransport des Garnspulen-Handhabungscontainers

erfolgen kann.In a further embodiment of the method according to the invention, an actuation of the braking device of the bobbin handling container takes place, which is in particular

• motion-controlled with the provision of the bobbin handling container in the area of the bobbin winding machine,
• with the manufacture of the coupling between the spindle coupling element and the yarn winding machine coupling element,
• the beginning and / or end of the winding process of the yarn package,
• the release of the clutch and / or
• the removal of the bobbin handling container

can be done.

In a further embodiment of the method according to the invention a plurality of yarn packages are wound in Garnspulen handling containers successively. The bobbin handling containers are then stored in a storage device, which may for example be stacked next to each other by stacking bobbin handling containers and / or arranging bobbin handling containers, it being also possible for the bobbin handling containers to be provided via suitable coupling areas and / or. elements can be coupled together.

For a particular proposal of the invention, in a further process step, the yarn bobbins which are arranged in the yarn bobbin handling containers, which in turn are stored in the storage device, are rotated. Such rotation can be done manually. This can be done intermittently or constantly. The application of the rotational movement of the yarn packages can also be done via the spindle coupling element or with other application of a rotary motion. Such a rotational movement of the yarn packages during stocking takes place for the purpose that gravitational forces are not intended to permanently act on the winding in a peripheral region, but instead migrate in the circumferential direction with the twisting of the yarn packages.

For a further proposal, in the method the yarn is not taken out of the yarn package handling container for further use, but rather unwound from the yarn package in the yarn package handling container.

It is also possible that the yarn package is transported in the yarn package handling container, which can also be done in a land vehicle, a watercraft or by means of an aircraft.

Die Vorratseinrichtung ist mit einer Anordnung der Garnspulen-Handhabungscontainer in Reihen und/oder Stapeln der Garnspulen-Handhabungscontainer aufeinander gebildet.It is possible to use the bobbin handling container for a storage device for yarn packages, which are in particular yarn packages with a mass of the winding of more than 300 kg, in particular more than 500 kg or more than 800 kg. Such a storage device can, for example

• at a place of manufacture,
• at a processing location,
• at a storage location,
• on a vehicle,
• on a ship,
• on a train or
• on an airplane

be arranged. In the storage device, the bobbins are arranged in each case in Garnspulen handling containers. The storage device is formed with an arrangement of the yarn package handling container in rows and / or stacking the yarn package handling container to each other.

It is also possible that the storage device has a rotating device. With the rotating device, the yarn packages in the Garnspulen handling containers are rotated. In this case, the twisting of the yarn packages can successively take place successively, for example, in that a rotary drive successively engages in the respective spindle coupling elements of the yarn package handling containers and in each case brings about a rotational movement about a predetermined angle of rotation. But it is also possible that in the bobbin handling containers, the spindle coupling elements, spindles or bobbins are coupled together so that they can be rotated together. For example, the rotating device may be formed with a chain or a rack, which interacts with the lateral surface of the spindle, a drive element of the spindles or the spindle coupling element in such a way that movement of the chain or rack results in the common rotation of all yarn packages.

DESCRIPTION OF THE FIGURES

Fig. 1 shows a yarn package handling container 1 with a yarn package 2. The yarn package handling container 1 is formed with two end face parts 3, 4 and side parts 5. The front side parts 3, 4 and the side parts 5 form a housing or a frame 6. In the first rough approximation, the housing or the frame 6 is cuboid, wherein for the illustrated embodiment, the frame or the housing "skeletal" are formed with large-area openings, which is particularly the weight reduction. For the illustrated embodiment, the side parts 5 are formed with side struts 7a, 7b, 7c, which are rod-shaped here, as a solid or hollow profile or as a circular profile. The side struts 7 are arranged in the region of the longitudinal edges of the cuboid housing or frame 6. It is entirely possible that in the region of a side edge of the cuboidal housing or frame 6 no side strut 7 is arranged (see. Fig. 1 ). The side struts 7 are frontally screwed respectively to the end side parts 3, 4, whereby the housing or the frame 6 is rigid. For the illustrated embodiment, the front side parts 3, 4 with a horizontal lower strut 8, a horizontal upper strut 9 and a "X" forming connecting struts 10, 11, which opposite end portions of the struts 8, 9 connected to each other formed. In the crossing region of the connecting struts 10, 11, a storage area 12 is formed, which may be reinforced or expanded. In the storage areas 12 of the end side parts 3, 4, a spindle 15, which extends through the yarn package 2, is supported in each case via bearings 13, 14. A winding 16 may be wound directly on the spindle 15 or with the interposition of a Garnspulenkörpers such as a sleeve. With one or both end regions, the spindle 15 extends through the bearing region 12 of at least one end face part 3, 4. The end region of the spindle 15 projecting outward from the end face part 4 forms a spindle coupling element 17 which is in Fig. 1 is shown only schematically. The housing or the frame 6 form the side of the yarn package 2 at the level of the longitudinal and rotational axis 53 of the spindle 15 an opening 18, through which the yarn package 2 and without winding 16, the spindle 15 are freely accessible. On the side facing the bottom, the undersides of the front side parts 3, 4 (and, in certain circumstances, also of the side parts 5) form a support region 19. It is also possible that in the support areas 19 projections 37 or depressions are provided. On the upper side, the front side parts 3, 4 (and possibly the side parts 5) have recesses 20 for the illustrated embodiment. If several bobbin handling containers 1 are stacked on one another, projections 37 can be provided in the support areas 19 of a first yarn bobbin handling container 1 arranged second bobbin handling container 1 positively engage in the recesses 20 of the arranged below the first bobbin handling container. 1

Fig. 2 shows a Garnspulma6schinen assembly 21. The Garnspulmachine assembly 21 is provided with a Garnspulen-handling container 1 according to Fig. 1 and a yarn winding machine 22, which is formed here for simplicity of illustration only with a winding station formed. In Fig. 2 the Garnspulmaschine 22 is shown only schematically. It can be seen here, however, that the yarn winding machine 22 is formed with a traversing device 28 and a feeding device for the yarn, which has a plurality of rollers and dancer arms 23, 24, 25. The yarn winding machine 22 has a support region 26. It is possible that the yarn package handling container 1 rests with the support region 19 on the support region 26 of the yarn winder 22. Here, a centering and / or positive securing the position of the bobbin handling container 1 relative to the Garnspulmaschine 22 by interaction of projections 37 and depressions in the support areas 19, 26 take place.

As will be explained in more detail below, the spindle coupling element 17 is rotatably coupled with a Garnspulmaschinen coupling element 27 so that a drive of the Garnspulmaschine 22 can cause the rotation of the spindle 15 and yarn package 2 of the Garnspulen handling container 1. Thus, by winding the yarn winding machine 22, namely driving the yarn winding machine coupling element 27 and feeding and applying the yarn over the rollers and dancer arms 23 to 25 and the traversing device 28, a winding 16 of the yarn package 2 can be produced for the yarn package machine assembly 21. After completion of the winding 16 of the yarn package handling container 1 with the housing or frame 6 and the spindle 15 and yarn package 2 is then removed from the Garnspulmaschine 22.

Fig. 3 shows an alternative embodiment of a bobbin handling container 1, in which all side edges of the cuboid housing or frame 6 in the first approximation with side struts 7a, 7b, 7c, 7d are formed. Here, the front side parts 3, 4 are formed with solid plates 29, 30, which are basically rectangular or square and are connected in the region of their corners with the side struts 7. For this embodiment, the extends in Fig. 3 On the rear side disposed opening 18 not only in the side region of the cuboid housing or frame 6. Rather, the plates 29, 30 here have U-shaped cutouts 31 which extend from the storage area 12 at the level of the axis of rotation of the spindle 15 to the outside. It can be seen in Fig. 3 in that the plates 29, 30 can have recesses 32, 33, which u. U. open in recesses or a hollow Interior of the side struts 7. With these recesses 32, 33 handling areas 34, 35 are formed, which allow the handling of the bobbin handling container 1. For example, in the handling areas 34, 35 trunnions are introduced, by means of which a lifting of the bobbin handling container 1 is possible. In Fig. 3 It will also be appreciated that additional stiffening struts 36 may be present. These serve in particular for the rigid support of the bearing area 12 for the bearings 13, 14.

In Fig. 4 are in the support region 19, the projections 37, here pins, can be seen. The projections 37 can serve to ensure a form-fitting, positionally accurate arrangement of the bobbin handling container 1 in the support region 26 of the yarn winder 22 or on a carriage 63, including the projections 37 in recesses with a corresponding cross-section of the support region 26 of the yarn winder 22 or the carriage 63rd enter. If a plurality of bobbin handling containers 1 are stacked for storage or during transport, the projections 37 of a bobbin handling container 1 can enter the recesses 20 on the upper side of a bobbin handling container 1 arranged thereunder.

In the longitudinal section according to Fig. 4 It can be seen that the bearing portions 12 are formed for the bearings 13, 14 with bearing rings 38, 39 which are welded to the end face parts 3, 5, the plates 29, 30, the connecting struts 10, 11 and / or the stiffening struts 36, are integrally formed by these or otherwise firmly connected thereto. On a hollow cylindrical inner surface of the bearing rings 38, 39, the bearings 13, 14 are radially outwardly supported. Radial inside is based on the bearings, 13, 14, the spindle 15 in their end regions. For the illustrated embodiment, the spindle coupling element 17 is formed with a hollow cylindrical inner surface 40 of the spindle 15. For the illustrated embodiment, the spindle 15 is formed as a hollow shaft. As will be explained in more detail below, there is a frictional transmission of a drive torque to the spindle 15 via the spindle coupling element 17 by a drive pin 52 of the yarn winder 22 or a friction element 58 of the drive pin 52 radially outwardly against the cylindrical inner surface 40 of the spindle 15th is pressed.

As an optional further component shows Fig. 4 a braking device 41 of the yarn package handling container 1. For the in Fig. 4 illustrated embodiment is the braking device 41 is formed with an elastic friction body 42 which rotates with the spindle 15 and to generate the braking action against the frame or the housing 6, here a hollow cylindrical inner surface 43 of the bearing ring axially adjacent to the bearing 14, can be braced. For this purpose, an actuating element 44, here likewise a hollow shaft 45, is guided axially displaceably radially inwardly from the spindle 15 designed as a hollow shaft. For the illustrated embodiment, the guide of the hollow shaft 45 via the spaced inside the spindle 15 fixed to the spindle 15 guide rings 46, 47. In the outwardly projecting out of the guide ring 46 end portion of the hollow shaft 45 carries the elastic friction body 42, which also here is designed as a ring body. Here, the elastic friction body 42 is supported on the outer side on a support ring 48, which is supported by the hollow shaft 45. In the opposite end region, the hollow shaft 45 carries a contact and Abstützscheibe 49. Between the guide ring 47 and the contact and Abstützscheibe 49 a radially outboard the hollow shaft 45 surrounding brake spring 50 is caught. The brake spring 50 is biased such that it acts on the hollow shaft 45 so that over the support ring 48 of the elastic friction body 42 is pressed against the guide ring 46 and is elastically deformed such that the elastic friction body 42 expands radially outwardly, so this to produce the braking action against the hollow cylindrical inner surface 43 of the bearing ring 49 is pressed. Occurs with approach of the bobbin handling container 1 to a drive pin 52 of a yarn winder 22 of the drive pin 52 in the interior of the spindle 15, the drive pin pushes the contact and Abstützscheibe 49 and thus the hollow shaft 45, the support ring 48 and the elastic friction body 42 against the application by the brake spring 50 in Fig. 4 to the left. With the thus caused movement, the elastic friction body 42 relaxes, whereby the frictional force between the elastic friction body 42 and the inner surface 43 of the bearing ring 39 is reduced and eliminated and the braking device 41 is released. The entry of the drive pin 52 for releasing the braking device 41 can be used simultaneously to bring about the drive-fixed connection between the drive pin 52 and the spindle 15 via the coupling of the spindle coupling element 17 with the Garnspulmaschinen coupling element 27.

Fig. 5 shows in a spatial representation of the Garnspulmaschinen assembly 21 with the Garnspulmaschine 22 and a yarn package handling container 1, wherein Fig. 6 and 7 show the Garnspulmaschinen assembly 21 with a partial longitudinal section, namely Fig. 6 before releasing the brake device 41 and before the coupling of the spindle coupling element 17 with the Garnspulmaschinen coupling element 27 and Fig. 7 after releasing the brake device 41 and after the coupling of the spindle coupling element 17 with the Garnspulmaschinen coupling element 27th

During the approach of the bobbin handling container 1 to the yarn winder 22, the yarn bobbin handling container 1 is guided by a guide device 51. By means of the guide device 51, the bobbin handling container is guided such that the approach to the yarn winder 22 with coaxial alignment of the drive journal 52 the Garnspulmaschine 22 to the longitudinal and rotational axis 53 of the spindle 15 takes place. It is possible that the guide device 51 has two guide units 54, which are designed here as a guide rail 55. The guide rails 55 are oriented parallel to the axis of rotation of the drive pin 52. The bobbin handling container 1 may have four guide units 56 in its support area 19. Two guide units 56 each are assigned to a guide rail 55. The guide units 56 engage round the guide rail 55 in a form-fitting manner, so that a guidance of the movement of the yarn package handling container 1 relative to the yarn winder 22 takes place. For the embodiment shown here but has the Garnspulmaschine 22 a carriage 63, on the underside of the guide units 56 are arranged and with the guide rails 55 interact. The bobbin handling container 1 is supported by the support area 19 on the carriage 63, wherein a centering or positive position securing can be carried out by entering the projections 37 of the bobbin handling container 1 in corresponding recesses of the carriage 63.

With the approach of the yarn package handling container 1 to the yarn winder 22, the drive pin 52 enters the yarn package handling container 1, here the interior of the spindle 15 (see transition from FIG Fig. 6 to Fig. 7 ). This movement of the bobbin handling container 1 is caused by an external handling device. It is also possible, however, for the bobbin handling container 1 to be brought into operative connection with the guide device 51, while at least part of the approaching movement is brought about by a drive device (not shown here) of the guide device 51 or of the carriage 63 Drive pin 52 is actuated (as described above) of the drive pin 52, which thus forms a brake actuator 57, the braking device 41, whereby a release of the brake device 41 takes place. Before, with or after the release of the braking device 41 is the Garnspulmaschinen coupling element 27, which is formed here by the drive pin 52, coupled to the spindle coupling element 17. Here, the Garnspulmaschinen coupling element 27 is formed as a friction member 58 which is acted upon radially outwardly against the hollow cylindrical inner surface 40 of the spindle 15. It is possible that the friction element 58 is also formed as an elastic friction body, which is axially compressed by axial loading via an actuator with a concomitant radial expansion. In the in Fig. 7 brought about state, the braking device 41 is released and via the contact of the friction element 58 with the spindle 15 there is a drive-fixed coupling of the drive pin 52 with the spindle 15. The rotationally fixed coupling between the drive pin 52 and the hollow shaft 45 can by the frictional contact between the end face of the drive pin 52 and the contact and Abstützscheibe 49 and / or by a positive connection of the cross sections of the hollow shaft 45 and the guide rings 46, 47, which allows the required axial movement of the hollow shaft 45, can be ensured.

Fig. 8 shows in detail the braking device 41 with the bearing 14 between the bearing ring 39 and an end portion of the spindle 15 (detail VIIIa) and the brake actuator 57 with the bearing 13 between the bearing ring 38 and the other end portion of the spindle 15 with frictionally coupled spindle coupling element 17th and Garnspulmaschinen coupling element 27 (detail VIIIb).

In a Fig. 8 corresponding representation shows Fig. 9 a modified embodiment in which not a frictional braking device 41 is used, but rather a positive brake device 41, which may also be referred to as a locking device (see detail Ixa). In this case, the hollow shaft 45 carries in the protruding from the guide ring 46 end portion instead of the support ring 48 and the elastic friction body 42, a locking body 59, the effective surface is formed non-circular. For example, the locking body 59 may be formed with grooves, projections or as a locking toothing. The bearing ring 39 also forms on its radially inner side of a locking body 60 or carries this. With actuation of the brake actuator 57 is the locking body 59 so far pushed out of the bearing ring 39 with the hollow shaft 45 that the locking body 59, 60 have no axial overlap, which no locking or braking takes place and the spindle 15 is freely rotatable. Without actuation of the brake actuator 57, so for removed from the bobbin handling container 1 drive pin 52, the hollow shaft 45 moves as a result of the brake spring 50, the locking body 60 in the locking body 59, whereby a positive locking or braking takes place. UU, the locking body 59, 60 also have insertion bevels, which allow the lock not only at defined angular orientations of the locking body 59, 60.

According to detail IXb, the coupling between the spindle coupling element 17 and the yarn winding machine coupling element 27 likewise takes place in a form-fitting manner. Here the yarn winding machine coupling element 27 associated with the drive pin 52 is formed with projections, ribs or splines 61. Accordingly, the spindle 15 is formed in the region of a recess or the inner surface with recesses, grooves or a spline 62 in the associated end region. With the introduction of the drive pin 52, the projections, recesses, ribs, grooves or splines 61, 62 interact positively in order to form a drive-proof connection. Again, chamfers can be provided.

Possible is different Fig. 8 and 9 Also, that the braking device 41 is based on a frictional engagement, while the coupling between the spindle coupling element 17 and the Garnspulmaschinen coupling element 27 based on a positive connection (or vice versa).

Fig. 10 shows the storage of a plurality of yarn package handling container 1 in a storage device 64. Here, a plurality of bobbin handling containers 1 are stacked in stacks 65, with a plurality of such stacks 65 are arranged directly adjacent to each other, so that the yarn package handling container 1 in a plurality of superposed rows 66th are arranged. In this case, adjacent bobbin handling containers 1 can be connected to one another, for which purpose, for example, projections 37 on the underside of a bobbin handling container 1 can engage in recesses 20 on the upper side of a bobbin handling container 1 arranged thereunder.

For that in the Fig. 11 and 12 illustrated embodiment, a handling device or rotator 67 is provided in the region of the storage device 64. The rotary device 67 has a drive pin 68. The drive pin 68 is equipped with a rotary device coupling element 69, which is preferably formed according to the Garnspulmaschinen coupling element 27. By means of suitable actuators, the turning device 67 can be located in the region of each bobbin handling container 1 of the storage device 64 are arranged. The drive pin 68 can then be aligned coaxially with the longitudinal and rotational axis 53 of the spindle 15 of the bobbin handling container. The drive pin 68 will then be inserted into the yarn package handling container 1 so that the rotary device coupling element 69 is coupled to the spindle coupling element 17 (frictional or positive locking) in a manner fixed to drive. With simultaneous solution of the braking device 51 of this Garnspulen handling container 1 can then be done by driving the rotator 67 with predetermined rotation angle of the drive pin 68, a twisting of the yarn package 2 in the Garnspulen handling container 1 to avoid adverse effects on the winding due to permanently acting gravitational forces. In this way, all of the yarn packages 2 in the yarn package handling containers 1 are successively rotated. In the event that yarn package handling containers 1 of different types are arranged in a storage device 64, the rotating device 67 can also be provided with different drive pins 68 and / or rotary coupling elements 69 are equipped, which are then selectively used.

Preferably, the use of the yarn package handling container 1 according to the invention, the yarn package assembly 21 and the method in connection with the production of carbon fibers, including viscose may be used. For this purpose, first a fibrous carbonaceous starting material is prepared, which is in particular polyacrylonitrile (PAN) or so-called "precursor". This fibrous carbonaceous raw material is wound into a yarn package, stored as a yarn package and then unwound for further processing. Here, further processing is pyrolysis (oxidation and carbonization) during which the fibrous carbonaceous feedstock is converted to graphitized carbon. Preferably, the yarn is a multifilament, which can be composed of more than 12,000 individual filaments (this is also known as 12 K). It is possible that between 12,000 and 300,000 individual filaments are present in the yarn cross-section. If, for example, a 500 kg spool is used with a PAN fiber sliver with 12 K single filaments, the length of the yarn may be 305,000 m, while for a yarn spool of 1,000 kg this length is 610,000 m. The resulting weight / length is (1,640 g) / (1,000 m) or 14,760 g [9,000 m]. Preferably, the yarn is bendable. The yarn package 2 is preferably equipped with a cross winding. The feeding speed of the yarn is preferably more than 50 m / min. For example, the diameter of a sleeve or the Outside diameter of the spindle 15 at least 150 mm. This results in a speed of about 106 min ^-1 for the beginning of the winding process. The maximum diameter of the winding 16 may be 1,200 mm or even more. This results in a speed of 13.3 min ^-1 at the end of the winding process. Deviations from the above values by +/- 20%, +/- 10% or +/- 5% are also possible.

Notwithstanding the illustrated embodiment with formation of the yarn winder 22 with traversing device 28 with resting during winding or unwinding Garnspulen handling container 1 is also possible that the Garnspulen handling container 1 is moved while the supply of the yarn takes place stationarily without the use of a traversing device 28 ,

For the illustrated embodiments, the spindle 15 is mounted in both end areas in the bearings 13, 14 on the end face parts 3, 4. It is quite possible that the storage is freely cantilevered from a front side part. It is possible here that in order to avoid a "flying load" of such a one-sided bearing on a front side part 3, 4, the front side part 3, 4 rigidly carries a pin which extends into the interior of a spindle formed as a hollow shaft 15. Between spindle 15 and the end portion of this pin can then act at least one bearing. It is advantageous here if the at least one bearing is then in the axial region of the center of gravity of the yarn package 2. Preferably, in this case, said pin is arranged on the drive-side end portion 3, while the spindle 15 extends with the spindle coupling element 17 from the other end face part 4 out.

It is also possible that in principle the spindle 15 or an associated sleeve rests with its own weight on a leading lateral surface, whereby basically a rotation due to the dead weight is excluded and thus a braking device is formed. With coupling of the bobbin handling container 1 to the yarn winder 22, a pressurization of air bearings in the region of the leading lateral surface can then take place, whereby then the rotational degree of freedom of the spindle 15 or associated sleeve is released.

Also, a handling device for handling the handling container 1 u. Deviating from the prior art: While for conventional yarn packages 2 the Handling device must have a spindle or a fixed pin on which the yarn package 2 must be pushed by the spindle of the winder, the handling device is not equipped with a spindle for handling the handling container 1 according to the invention. Rather, such a handling device occurs only with the housing or frame 6 of the handling container 1, the braking device 41, any holding areas, the support area 19, protrusions 37 or recesses and / or handling areas 34, 35 in operative connection. It is also possible that such a handling device has a coupling element which can come into operative connection with the spindle coupling element 17 of the handling container.

If a bearing of the spindle 15 only takes place on one end face part 3, 4, the other end face part 4 can also be dispensed with, whereby a removal of the yarn package 2 from the handling container 1 is also possible. It is also possible that the handling container 1 itself has a drive for the spindle 15 or a traversing device, which are then suitably controlled by coupling with the winder 22 by this.

The opening 18 can also be used to ensure that a traversing yarn guide of the traversing device 28 can be guided as close as possible to the yarn package 2, so that the shortest possible drag path of the yarn from the traversing yarn guide of the traversing device 28 to the depositing location on the yarn package 2 results positively affects the quality of the bobbin. It is also possible that this embodiment enables the use of a pressure roller on the traversing device 28, which fixes the deposited yarn on the yarn package 2 and contributes to the solidification of the yarn package 2. After completion of the winding operation, the traversing device 28 is again removed from the opening 18 in the radial direction to allow the disassembly of the handling container 1 of the yarn winder 22.

The unwinding of the bobbin 2 can be analogous to winding on a unwinding Garnspulmaschine 22, which is in particular formed without traversing device, take place, in which case it is conceivable that the yarn package 2 is driven during unwinding or also braked. In this case, the transmission of the driving or decelerating torque can also take place via the spindle coupling element 17 of the yarn package handling container 1. Preferably, the yarn package 2 without a drum, in particular a drum with the end faces of the winding 16 limiting drum discs formed.

The invention finds use with the automated winding and / or unwinding of a technical yarn. In particular, a controlled drive is used. Special measures may be taken at the handling container 1 and / or the yarn winding machine 22 for catching the yarn at the beginning of the winding process. Thus, for example, the handling container 1 with a fishing hook, a clamping device o. Ä. Be equipped, by means of which catching and fixing of the supplied yarn can take place, the creation of a so-called fixing winding can be done u. Ä. Here, an automatic feed of the yarn can be done. It is also possible that the yarn is fed manually at the beginning of the winding process.

In the bobbin handling container 1, any other, not shown here components may be present. By way of example only, the bobbin handling container 1 may be provided with a receiving body for documentation material such as yarn, processing and manufacturing process of the yarn, date of manufacture, transport path, customs information or method of use for the yarn and the like. Ä., Be equipped. It is also possible that corresponding information is stored on a data carrier of the bobbin handling container, which can be wired or wirelessly described and / or read. It is also possible that the bobbin handling container is designed with an electronic control unit which operates autonomously or is networked with the connection of the bobbin handling container 1 with a yarn winder 22 with an electronic control unit of the yarn winder 22. For example, the control of an actuator for the braking device 41 can take place via such an electronic control unit of the bobbin handling container 1. The bobbin handling container 1 may also have a battery or an accumulator. Any other components may also be provided in or on the bobbin handling container 1, in particular in the region of the housing or frame 6.
