DETAILED DESCRIPTION OF

[0116] FIG. 1 shows a yarn spool handling container 1 with a yarn spool 2. The yarn spool handling container 1 is formed with two front face parts 3, 4 and side parts 5. The front face parts 3, 4 and the side parts 5 form a housing or a frame 6. In a first rough approximation, the housing or the frame 6 is cube-shaped, where for the embodiment shown the frame or the housing are realized in a “skeleton-like way” with large opening, which serves especially for reducing weight. For the embodiment shown, the side parts 5 are formed with side trusses 7a, 7b, 7c which here are rod-shaped, realized as a solid profile or hollow profile or as a circular profile. The side trusses 7 are arranged in the region of the longitudinal edges of the cube-shaped housing or frame 6. It is possible that in the region of a side edge of the cube-shaped housing or frame 6 no side truss 7 is arranged (cp. FIG. 1). The side trusses 7 on their front faces are each screwed to the front face parts 3, 4, in which way the housing or the frame 6 is realized as inflexible. For the embodiment shown, the front face parts 3, 4 are formed with a horizontal lower truss 8, a horizontal upper truss 9 and connecting trusses 10, 11 forming an “X”, which connect opposing end portions of the trusses 8, 9. In the crossing portion of the connecting trusses 10, 11, a bearing portion 12 is formed which can be reinforced or widened. In each of the bearing portions 12 of the front face parts 3, 4, a spindle 15, which extends through the yarn spool 2, is supported via bearings 13, 14. A winding 16 can be wound directly onto the spindle 15 or by interposition of a yarn spool body such as a sleeve. With one or both end portions the spindle 15 extends through the bearing portion 12 of at least one front face part 3, 4. The end portion of the spindle 15 protruding outwards from the front face part 4 forms a spindle coupling element 17, which in FIG. 1 is only schematically shown. The housing or the frame 6 form an opening 18 to the side of the yarn spool 2 at the level of the longitudinal and rotational axis 53 of the spindle 15 through which the yarn spool 2 and, without a winding 16, the spindle 15 are freely accessible. On the side turned towards the floor, the undersides of the front face parts 3, 4 (and possibly also of the side parts 5) form a supporting portion 19. It is also possible that in the supporting portions 19 protrusions 37 or indentations are provided. On the upper side, the front face parts 3, 4 (and possibly also the side parts 5) have openings 20 for the embodiment shown. If several yarn spool handling containers 1 are stacked one on the other, protrusions 37 in the supporting portions 19 of a second yarn spool handling container 1 arranged above a first yarn spool handling container 1 can form-lockingly engage with the openings 20 of the first yarn spool handling container 1 arranged below it.

[0117] FIG. 2 shows a yarn spooling machine assembly 21. The yarn spooling machine assembly 21 is formed with a yarn spool handling container 1 according to FIG. 1 and a yarn spooling machine 22 which here is realized only with a spooling station to simplify the representation. In FIG. 2, the yarn spooling machine 22 is only schematically shown. It can, however, be seen that the yarn spooling machine 22 is formed with a traversing unit 28 and a feeding device for the yarn which comprises several rolls and dancer arms 23, 24, 25. The yarn spooling machine 22 comprises a supporting portion 26. It is possible that the yarn spool handling container 1 stands on the supporting portion 26 of the yarn spooling machine 22 with the supporting portion 19. There can be a centering and/or a form-locking securing of the position of the yarn spool handling container 1 relative to the yarn spooling machine 22 by interaction of protrusions 37 and indentations in the supporting portions 19, 26.

[0118] As will be explained in more detail in the following, the spindle coupling element 17 is coupled rotationally fixedly with the yarn spooling machine coupling element 27 so that a drive of the yarn spooling machine 22 can induce the rotation of the spindle 15 and the yarn spool 2 of the yarn spool handling container 1. In this way, for the yarn spool machine assembly 21 by operating the yarn spool machine 22, that is, driving the yarn spooling machine coupling element 27 and feeding and laying of the thread via the rolls and dancer arms 23 to 25 and the traversing unit 28 a winding 16 of the yarn spool 2 can be produced. After completing the winding 16, the yarn spool handling container 1 with the housing or frame 6 and the spindle 15 and the yarn spool 2 is removed from the yarn spooling machine 22.

[0119] FIG. 3 shows an alternative embodiment of a yarn spool handling container 1 in which all side edges of the housing or frame 6 that in a first approximation is cuboid are formed with side trusses 7a, 7b, 7c, 7d. The front face parts 3,4 are formed with massive plates 29, 30, which are generally rectangular or square and in the region of their corners are connected to the side trusses 7. For this embodiment, the opening 18 arranged on the back side in FIG. 3 does not only extend in the side portion of the cuboid housing or frame 6. Rather than that, the plates 29, 30 here have U-shaped cutouts 31 which extend outwards from the bearing portion 12 at the level of the rotational axis of the spindle 15. It can be seen in FIG. 3 that the plates 29, 30 can have openings 32, 33 which possibly open into openings or a hollow interior of the side trusses 7. With these openings 32, 33, handling portions 34, 35 are formed which enable the handling of the yarn spool handling container 1. For example, into the handling portions 34, 35 supporting pins can be inserted by means of which a lifting of the yarn spool handling container 1 is possible. In FIG. 3 it can also be seen that additional stiffening trusses 36 can be present. These stiffening trusses 36 serves especially for the stiff support of the bearing portion 12 for the bearings 13, 14.

[0120] In FIG. 4 the protrusions 37, here pins, can be seen in the supporting portion 19. The protrusions 37 can serve for guaranteeing a form-locking, position-accurate arrangement of the yarn spool handling container 1 in the supporting portion 26 of the yarn spooling machine 22 or on a carriage 6, in order to achieve which the protrusions 37 enter into openings of the supporting portion 26 of the yarn spooling machine 22 or the carriage 63 with a corresponding cross section. If for the stocking or during a transport several yarn spool handling containers 1 are stacked one on the other, the protrusions 37 of one yarn spool handling container 1 can enter into the openings 20 on the upper side of a yarn spool handling container 1 arranged below.

[0121] In the longitudinal section according to FIG. 4 it can be seen that the bearing portions 12 for the bearings 13, 14 are formed with bearing rings 38, 39, which are welded together with the front face parts 3, 5, the plates 29, 30, the connecting trusses 10, 11 and/or the stiffening trusses 36, are integrally formed by the mentioned elements or in other way are fixedly connected to the mentioned elements. On a hollow cylindrical interior surface of the bearing rings 38, 39 on the radially outer side the bearings 13, 14 are supported. On the radially inner side, the spindle 15 in its end regions is supported on the bearings 13, 14. For the embodiment shown, the spindle coupling element 17 is realized with a hollow cylindrical interior surface 40 of the spindle 15. For the embodiment shown, the spindle 15 is realized as a hollow shaft. As will be explained in more detail in the following, a friction-locking transmission of a drive torque onto the spindle 15 via the spindle coupling element 17 is achieved by a drive spigot 52 of the yarn spooling machine 22 or a friction element 58 of the drive spigot 52 being pressed against the cylindrical interior surface 40 of the spindle 15 in a radially outwards direction.

[0122] As an optional further component, FIG. 4 shows a brake device 41 of the yarn spool handling container 1. For the embodiment shown in FIG. 4, the brake device 41 is formed with an elastic friction body 42, which rotates with the spindle 15 and can be tensioned against the frame or the housing 6, which here is represented by a hollow cylindrical interior surface 43 of the bearing ring arranged axially besides the bearing 14, to produce a braking effect. In order to achieve this, radially on the inner side of the spindle 15 realized as a hollow shaft an actuation element 44, which here also is a hollow shaft 45, is guided to be slidable axially. For the embodiment shown, the guiding of the hollow shaft 45 is achieved via the guiding rings 46, 47 fixed to the spindle 15 with a distance in the interior of the spindle 15. In the end region protruding outwardly from the guiding ring 46, the hollow shaft 45 supports the elastic friction body 42 which here also is realized as a ring body. The elastic friction body 42 on the outer side is supported on a supporting ring 48 which is supported by the hollow shaft 45. In the opposite end portion, the hollow shaft 45 supports a contact and supporting disc 49. Between the guiding ring 47 and the contact and supporting disc 49, a brake spring 50 surrounding the hollow shaft 45 on the radially outer side is captured. The brake spring 50 is pretensioned in such a way that it biases the hollow shaft 45 in such a way that via the supporting ring 48 the elastic friction body 42 is pressed against the guiding ring 46 and is elastically deformed in such a way that the elastic friction body 42 expands radially outwardly, in which way it is pressed against the hollow cylindrical interior surface 43 of the bearing ring 49 to produce the braking effect. If with the approach of the yarn spool handling container 1 to a drive spigot 52 of a yarn spooling machine 22 the drive spigot 52 enters into the interior of the spindle 15, the drive spigot presses the contact and supporting disc 49 and therefore the hollow shaft 45, the supporting ring 48 and the elastic friction body 42 to the left in FIG. 4 against the biasing by the brake spring 50. With the motion induced in this way, the elastic friction body 42 relaxes, in which way the friction force between the elastic friction body 42 and the interior surface 43 of the bearing ring 39 is decreased and removed and the brake device 41 is released. The entering of the drive spigot 52 for releasing the brake device 41 can at the same time be used to induce the drive-torque-fixed connection between the drive spigot 52 and the spindle 15 via the coupling of the spindle coupling element 17 to the yarn spooling machine coupling element 27.

[0123] FIG. 5 in a spatial representation shows the yarn spooling machine assembly 21 with the yarn spooling machine 22 and the yarn spool handling container 1, where FIGS. 6 and 7 show the yarn spooling machine assembly 21 in a partial longitudinal section; that is, FIG. 6 before the release of the brake device 41 and before the coupling of the spindle coupling element 17 to the yarn spooling machine coupling element 27 and FIG. 7 after the release of the brake device 41 and after the coupling of the spindle coupling element 17 to the yarn spooling machine coupling element 27.

[0124] During the approach of the yarn spool handling container 1 to the yarn spooling machine 22, the guiding of the yarn spool handling container 1 is done by a guiding device 51. By means of the guiding device 51, the yarn spool handling container is guided in such a way that the approach to the yarn spooling machine 22 is achieved with a coaxial alignment of the drive spigot 52 of the yarn spooling machine 22 to the longitudinal and rotational axis 53 of the spindle 15. It is possible that the guiding device 51 comprises two guiding units 54 which here are realized as a guiding rail 55. The guiding rails 55 are oriented in parallel to the rotational axis of the drive spigot 52. The yarn spool handling container 1 in its supporting portion 19 can comprise four guiding units 56. Two guiding units 56 each are assigned to one guiding rail 55. The guiding units 56 in a form-locking way wrap around the guiding rail 55, so that a guiding of the motion of the yarn spool handling container 1 relative to the yarn spooling machine 22 is achieved. For the embodiment shown, however, the yarn spooling machine 22 has a carriage 63 on the underside of which the guiding units 56 are arranged and come into interaction with the guiding rails 55. The yarn spool handling container 1 is supported on the carriage 63 with the supporting portion 19, where a centering or a form-locking securing of the position can be achieved by the protrusions 37 of the yarn spool handling container 1 entering into corresponding openings of the carriage 63.

[0125] With the approach of the yarn spool handling container 1 to the yarn spooling machine 22, the drive spigot 52 enters into the yarn spool handling container 1, which here is the interior of the spindle 15 (see the transition from FIG. 6 to FIG. 7). This movement of the yarn spool handling container 1 is caused by an external handling device. It is also possible, however, that the yarn spool handling container 1 is only brought into effective connection with the guiding device 51 while at least a part of the approaching motion is induced by a driving device of the guiding device 51 or the carriage 63 (not shown here). With the entering of the drive spigot 52, the drive spigot 52, which therefore forms a brake actuation device 57, actuates (as explained before) the brake device 41, in which way a release of the brake device 41 occurs. Before, while or after the releasing of the brake device 41 the yarn spooling machine coupling element 27, which here is realized by the drive spigot 52, is coupled with the spindle coupling element 17. The yarn spooling machine coupling element 27 is realized as a friction element 58 which is biased radially outwardly against the hollow cylindrical interior surface 40 of the spindle 15. It is possible that the friction element 58 is also realized as an elastic friction body which is axially compressed by axial biasing via an actuator—with an accompanying radial extension. In the state induced in FIG. 7, the brake device 41 has been released and via the contact of the friction element 58 with the spindle 15 there is a drive-torque-fixed coupling of the drive spigot 52 with the spindle 15. The drive-torque-fixed coupling between the drive spigot 52 and the hollow shaft 45 can be guaranteed by the friction contact between the front face of the drive spigot 52 and the contact and supporting disc 49 and/or a form-locking of the cross sections of the hollow shaft 45 and the guiding rings 46, 47, which enables the necessary axial movement of the hollow shaft 45.

[0126] FIG. 8 in detail shows the brake device 41 with the bearing 14 between the bearing ring 39 and an end region of the spindle 15 (detail Villa) and the brake actuation device 57 with the bearing 13 between the bearing ring 38 and the other end portion of the spindle 15 with the spindle coupling element 17 and yarn spooling machine coupling element 27 (detail VIIIb) friction-lockingly coupled.

[0127] In a representation corresponding to FIG. 8, FIG. 9 shows a modified embodiment in which not a friction-locking brake device 41 is used but rather a form-locking brake device 41, which can also be referred to as a locking device (see detail IXa). In this case, the hollow shaft 45 in the end portion protruding from the guiding ring 46 instead of the supporting ring 48 and the elastic friction body 42 supports a locking body 59 the active surface of which is realized to be not round. For example, the locking body 59 can be realized with notches, protrusions or as a locking toothing. The bearing ring 39 on its radially inner side also forms a locking body 60 or supports the locking body 60. At the actuation of the brake actuation device 57, with the hollow shaft 45 the locking body 59 is pushed out of the bearing ring 39 so far that the locking bodies 59, 60 have no axial overlap, in which way there is no locking or braking and the spindle 15 is freely rotatable. Without actuation of the brake actuation device 57, that is, for the drive spigot 52 removed from the yarn spool handling container 1, the hollow shaft 45 due to the brake spring 50 presses the locking body 60 into the locking body 59, in which way a form-locking locking or braking is achieved. Possibly, the locking bodies 59, 60 can also comprise insertion bevels which enable the locking not only for defined angular alignments of the locking bodies 59, 60.

[0128] According to detail IXb, the coupling between the spindle coupling element 17 and the yarn spooling machine coupling element 27 is also form-lockingly: The yarn spooling machine coupling element 27 assigned to the drive spigot 52 is formed with protrusions, ribs, or a spline 61. Correspondingly, in the assigned end portion the spindle 15 is also realized with apertures, notches or a spline 62 in the region of an aperture or the interior surface. At the insertion of the drive spigot 52, the protrusions, indentations, ribs, notches or splines 61, 62 come into interaction in a form-locking way with the aim of forming a drive-torque-fixed connection. Insertion bevels can also be provided in this context.

[0129] In deviation to FIGS. 8 and 9, it is also possible that the brake device 41 is based on a friction-locking while the coupling between the spindle coupling element 17 and the yarn spooling machine coupling element 27 is based on a form-locking (or the other way around).

[0130] FIG. 10 shows the stocking of several yarn spool handling containers 1 in a stocking device 64. Several yarn spool handling containers 1 are stacked one above the other in stacks 65, where several such stacks 65 are arranged directly neighboring each other, so that the yarn spool handling containers 1 are also arranged in several rows 66 arranged one above the other. Neighboring yarn spool handling containers 1 can be connected to each other, in order to achieve which for example protrusions 37 on the underside of a yarn spool handling container 1 can engage with openings 20 on the upper side of a yarn spool handling container 1 arranged below.

[0131] For the embodiment shown in FIGS. 11 and 12, in the region of the stocking device 64 a handling device or rotating device 67 is provided. The rotating device 67 comprises a drive spigot 68. The drive spigot 68 is equipped with a rotating device coupling element 69 which is preferably realized correspondingly to the yarn spooling machine coupling element 27. Via suitable actuators the rotating device 67 can be arranged in the region of each yarn spool handling container 1 of the stocking device 64. The drive spigot 68 can then be aligned coaxially to the longitudinal and rotational axis 53 of the spindle 15 of the yarn spool handling container. The drive spigot 68 then will be inserted into the yarn spool handling container 1 in such a way that the rotating device coupling element 69 is coupled with the spindle coupling element 17 in a drive-torque-fixed way (friction-lockingly or form-lockingly). With a simultaneous release of the brake device 51 of this yarn spool handling container 1 and by driving the rotating device 67 with a specified rotational angle of the drive spigot 68 there can be a rotating of the yarn spool 2 in the yarn spool handling container 1 to avoid spoiling of the winding due to long-term effective gravitational forces. In this way, successively the rotation of all yarn spools 2 in the yarn spool handling containers 1 is achieved. For the case that in one stocking device 64 yarn spool handling containers 1 of different types are arranged, the rotating device 67 can also be equipped with different drive spigots 68 and/or rotating device coupling elements 69 which then are used selectively.

[0132] Preferably, the employment of the yarn spool handling container 1, the yarn spooling machine assembly 21 and the method according to the invention occurs in connection with the manufacture of carbon fibers, for which viscose can also be employed. In order to achieve this, at first a fiber-shaped carbon-containing starter material is produced, which is especially polyacrylonitrile (PAN) or a so-called precursor. This fiber-shaped carbon-containing starter material is wound into a yarn spool, stocked as a yarn spool and then unwound for further processing. The further processing consists of a pyrolysis (oxidation and carbonization) during which the fiber-shaped carbon-containing starter material is converted into carbon that is arranged in a graphite-like way. Preferably, the yarn is a multifilament which can be composed of more than 12,000 single filaments (this is also referred to as 12 K). It is possible that between 12,000 and 300,000 single filaments are present in the yarn cross section. If, for example, a spool of 500 kg with a PAN sliver with 12 K single filaments is employed, a length of the yarn of 305,000 m can result, while this length for a yarn spool with a mass of 1,000 kg is 610,000 m. The weight/length resulting from this is (1,640 g)/(1,000 m) or 14,760 den [g/9,000 m]. Preferably, the yarn is flexible. The yarn spool 2 preferably is equipped with a cross-winding. The feeding speed of the yarn preferably is higher than 50 m/min. For example, the diameter of a sleeve or the outer diameter of the spindle 15 can be at least 150 mm. For the beginning of the spooling process a rotational frequency of about 106 min.sup.−1 results from this. The maximum diameter of the winding 16 can be 1,200 mm or even more. From this, at the end of the spooling process a rotational frequency of 13.3 min.sup.−1 results. Deviations from the aforementioned values by +/−20%, +/−10% or +/−5% are also possible.

[0133] In deviation to the embodiment shown with the realization of the yarn spooling machine 22 with the traversing unit 28 at the yarn spool handling container 1 being at rest during the winding and unwinding it is also possible that the yarn spool handling container 1 is moved while the feeding of the yarn is done in a stationary way without the use of a traversing unit 28.

[0134] For the embodiments shown, the spindle 15 in both end regions is supported in the bearings 13, 14 on the front face parts 3, 4. It is possible that the supporting is done freely protrudingly from a front face part. It is possible that in order to avoid an “overhang stress” of such a one-sided support on one front face part 3, 4, the front face part 3, 4 inflexibly supports a pin which extends into the interior of a spindle 15 realized as a hollow shaft. Between the spindle 15 and the end region of this pin at least one bearing can be effective. It is advantageous in this context if the at least one bearing is arranged in the axial region of the center of gravity of the yarn spool 2. Preferably, the mentioned pin is arranged on the front face part 3 far from the drive while the spindle 15 with the spindle coupling element 17 protrudes from the other front face part 4.

[0135] It is also possible that generally the spindle 15 or an assigned sleeve rests on a guiding outer surface with its own weight, in which way generally a rotation due to the own weight is excluded and therefore a brake device is formed. With a coupling of the yarn spool handling container 1 to the yarn spooling machine 22 then a pressurizing of air bearings in the region of the guiding outer surface can occur, in which way the rotational degree of freedom of the spindle 15 or the assigned sleeve is released.

[0136] A handling device for handling the handling containers 1 is also possibly realized in deviation to prior art: While for ordinary yarn spools 2 the handling device has to have a spindle or a fixed spigot onto which the yarn spool 2 has to be pushed from the spindle of the spooling machine, for handling of the handling container 1 according to the invention the handling device is not equipped with a spindle. Rather than that, such a handling device only comes into effective connection with the housing or frame 6 of the handling container 1, the brake device 41, possible holding portions, the supporting portion 19, protrusions 37 or apertures and/or handling portions 34, 35. It is also possible that such a handling device comprises a coupling element which can enter into effective connection with the spindle coupling element 17 of the handling container.

[0137] If a support of the spindle 15 is only done on a front face part 3, 4, the other front face part 4 can also be omitted in which way a removal of the yarn spool 2 from the handling container 1 is also possible. It is also possible that the handling container 1 itself comprises a drive for the spindle 15 or a traversing unit which then, at a coupling with the spooling machine 2, can be controlled in a suitable way 2 by the latter.

[0138] The opening 18 can also be used to guide a traversing thread guide of the traversing unit 28 as closely as possible to the yarn spool 2 so that a trailing path of the yarn from the traversing thread guide of the traversing unit 28 to the laying place on the yarn spool 2 results that is as short as possible, which has a positive effect on the spool quality. It is also possible that this realization enables the use of a removing roller on the traversing unit 28 which fixes the laid yarn on the yarn spool 2 and contributes to a compacting of the yarn spool 2. After the completion of the spooling process, the traversing unit 28 is removed again from the opening 18 in the radial direction to enable the unmounting of the handling container 1 from the yarn spooling machine 22.

[0139] The unwinding of the yarn spool 2 in an analogous way to the winding can be done on a yarn spooling machine 22 serving for unwinding, which is especially realized without a traversing unit, where it is thinkable that the yarn spool 2 is driven or braked in the unwinding. The transmission of the driving or braking torque can also be done via the spindle coupling element 17 of the yarn spool handling container 1. Preferably, the yarn spool 2 is realized without a drum, especially a drum with drum discs limiting the front faces of the winding 16.

[0140] The invention is employed with the automatic winding and/or unwinding of a technical yarn. In order to do this, especially a controlled drive is employed. Special measures can have been made on the handling container 1 and/or the yarn spooling machine 22 for catching the yarn at the beginning of the spooling process. For example, the handling container 1 can be equipped with a catching hook, a clamping device or similar by means of which a catching and fixing of the fed yarn can occur, the creation of a so-called fixing winding can occur or similar. In this context, an automatic feeding of the yarn can occur. It is also possible that the yarn is fed manually at the beginning of the spooling process.

[0141] In the yarn spool handling container 1 any further components not shown here can be present. To mention only an example, the yarn spool handling container 1 can be equipped with a receiving body for documentation material, for example with respect to the yarn, the processing and the manufacturing process of the yarn, a manufacturing date, the transport route, for customs-law information or usage advice for the yarn or similar. It is also possible that corresponding information is stored on a data storage medium of the yarn spool handling container, which can be written and/or read with or without a cable. It is also possible that the yarn spool handling container is equipped with an electronic control unit which works autonomously or is cross-linked with the connection of the yarn spool handling container 1 with a yarn spooling machine 22 with an electronic control unit of the yarn spooling machine 22. For example, the control of an actuator for the brake device 41 can occur via such an electronic control unit of the yarn spool handling container 1. Possibly, the yarn spool handling container 1 also has a battery or an accumulator. Any other components can also be provided in or on the yarn spool handling container 1, especially in the region of the housing or frame 6.
