Description

The invention relates to a winding support for the treatment of threads or yarns with two end rings and a plurality of intermediate rings forming elements which form a perforated outer ring, spacer elements connecting the intermediate ring elements and being arranged in the outer ring being provided.

Winding carriers of the type described above are widely used and have proven their worth. Depending on the application, a wide variety of deformation requirements are placed on such winding supports. Winding carriers of the known type can be cylindrical, conical or also biconical. Depending on the application, they must be rigid or axially flexible. Radial flexibility is also sometimes required. It can also be expedient that such winding carriers are designed to be axially flexible with a mandatory radial movement. They are sometimes both elastically and plastically deformable.

Depending on the required property, the structure of the winding carrier, in particular with regard to the design of the intermediate rings and the webs, is different, in adaptation to the desired deformability. For example, DE-G-1760 818 has disclosed such a winding carrier of simple construction, which is easily deformable both radially and axially.

An example of an axially compliant winding carrier construction can be found in DE-A-23 63 250. DE-A-17 60 652 shows an example of a winding carrier whose axial deformation inevitably leads to radial deformation.

Thus, in the prior art, winding carriers of the most varied of structures are known, in adaptation to the desired deformation.

Such winding carriers are preferably molded from plastic using a suitable tool. However, tools for the formation of winding supports of known structure have the disadvantage that the mold must have more than two mold jaws so that after the molding the tool parts can be moved apart and the molded part can be removed. This makes the tools very expensive and, if several winding carriers are to be formed in one molding process, also very large.

French winding no. 1416 340 discloses a winding carrier which can be shaped with a four-jaw tool. But even such a tool is still large and complicated in structure and therefore expensive, and it is difficult to change the structure of such a winding carrier in order to achieve different deformation properties.

Starting from the described prior art and from the winding carrier described at the outset, the innovation is based on the object of proposing a winding carrier which can be shaped with a two-jaw tool and which can still be varied in structure while maintaining such a tool, that all known, desired deformation properties can be achieved.

Starting from a winding carrier of the type described at the outset, this object is achieved in that all spacer elements have the same rectilinear lines perpendicular to a plane of division which is common to all and runs symmetrically to a diameter line of the carrier cross section. These rectified jacket lines represent the direction of displacement of two mold jaws, so that the winding carrier can be easily produced from such a molding tool due to the rectifier jacket lines of the spacer elements. At the same time, the spacer elements for producing certain deformation and elastic properties of the winding carrier can be designed in many ways, as long as they only meet the condition that they all have the same sheathed lines, which is the only way to create such a tool for shaping the winding carrier.

Since a two-jaw mold has only one parting plane, the presence of this parting plane results in an interesting embodiment of the invention, according to which on a first cutting plane along a diameter line (i.e. along the parting line of the two jaws) in an opposing arrangement and exactly one below the other a spacer element with a surface line parallel to the cutting plane is arranged between two elements forming such intermediate rings or such an element and the associated end ring and that further spacing elements are provided with surface lines which lie in cutting planes which are pivoted 90 ° out of the first cutting plane with respect to the latter . The latter spacer elements lie with their surface lines as already described above, while the former spacer elements are on the one hand exactly below one another and on the other hand in the parting plane of the two jaws, so that the separability of the tool is not affected by their changed arrangement, but a different design with other deformation behavior of the winding carrier can be achieved.

In a further embodiment of the forms of such winding carriers, it is also provided according to the invention that all the spacer elements, with the exception of the spacer elements which are assigned to the first sectional plane, are arranged offset in the circumferential direction with respect to the spacer elements arranged below or above them. The result of this is that the winding carrier can be deformed both axially and radially in spite of being able to be shaped with a two-jaw tool, and radial deformation is necessarily brought about in the event of an axial deformation. The applications and the advantages of certain deformability are known per se in the prior art. They should therefore not be repeated here. Rather, what is important here after the innovation is to design winding carriers of different deformability in such a way that they can be produced with a two-jaw molding tool. This is achieved with the respective proposals and designs of the innovation.

Also according to an embodiment of the invention it is provided that the spacer elements in Axial direction are rigid. This also achieves a desired deformation behavior of the winding carrier for certain applications. If all spacer elements are arranged strictly one below the other, a rigid winding body is achieved, while if these spacer elements rigid in the axial direction are offset in the different planes, a winding carrier is achieved which is both axially and radially flexible.

Another embodiment of the invention provides that all spacer elements, with the exception of the spacer elements which are assigned to the first sectional plane, are rigid in the axial direction, while the spacer elements associated with the first sectional plane are alternately rigid and soft in the axial direction. This arrangement is particularly advantageous if the rigid spacer elements are arranged offset in the planes. The winding carrier then becomes particularly soft in connection with the alternately rigid and soft spacer elements of the first sectional plane, both in the axial and in the radial direction.

In a supplementary embodiment of the invention, it is provided that the spacer elements assigned to the first sectional plane are designed to be soft in the axial direction in the planes with the rigid outer spacer elements. As a result, a uniform deformation of the winding carrier is achieved both in the axial and in the radial direction.

According to a variant of the invention it is proposed that the spacer elements are at least partially designed as boundary surfaces of hollow bodies which are open at least at the outer end. In this way, for example, pure axial deformability can be achieved, the deformation force of which is determined by the shape and the wall thickness of the hollow body. The size and force required for the axial deformation can therefore be determined by the dimensioning of these boundary surfaces, and the formability of the winding carrier is still retained using a two-jaw tool.

According to a supplementary embodiment of the invention, it is provided that only the outer or inner surface lines of the hollow bodies diverge in the direction of the inside or outside of the outer ring, while each line of intersection of the planes of symmetry of each hollow body runs perpendicular to the axial direction of the winding carrier and parallel to every other line of cut. As a result, the winding carrier as a whole, for example, can be made firmer in the core area and more flexible in the outer area. Here too, the winding carrier can still be produced with a two-jaw molding tool.

Another embodiment of the invention, in turn, provides that spacing elements are assigned to the first sectional plane at least according to claims 1 to 6, the surface lines of which converge, diverge or can run parallel to one another in the direction of the interior of the surface ring. This makes it possible to combine the hollow bodies as spacer elements with the flat spacer elements, as a result of which different deformability of the winding support can be achieved in different axially lying planes of symmetry. Here too, of course, and this also applies to all other refinements of the innovation, the manufacturability of the winding carrier is not impaired by a two-jaw molding tool.

Another embodiment of the invention in turn provides that ring segments are provided between the intermediate rings in an arrangement lying opposite one another on the winding support and with the first cutting plane as a plane of symmetry, which are carried by spacer elements. Depending on the design of the winding carrier selected, it is possible that gaps between the intermediate rings of undesirable size occur in the areas mentioned. The proposed measure reduces these gaps to the desired extent.

An additional embodiment of the invention provides that the intermediate rings have different diameters in a continuous sequence and / or in a periodic change. This makes it possible, while maintaining all previous options, to design a winding carrier that is not only cylindrical in its essential shape, but also for itself and also additionally conical, biconical or z. B. can be sinusoidal. These forms can also offer very specific advantages when treating certain fibers.

In addition to the previous design, it is also proposed according to the invention that in the same orientation as at least the spacer elements, which are not assigned to the first sectional plane, at least at the outer end open hollow bodies are formed in at least several intermediate rings, so that the intermediate rings in the circumferential direction of these Hollow bodies are interrupted. In this way, for example, a two-stage behavior of the winding carrier can be achieved with respect to the desired deformation directions. First, the deformation path of the elements originally intended for the deformation is exhausted, and an additional deformation path, as described above, can be used if necessary, depending on the external circumstances, for example for safety reasons. This additional possibility of deformation can be exploited separately in the axial as well as in the radial direction, or can be used in a combined manner.

Advantageously, according to a further embodiment of the invention, the hollow bodies which interrupt the intermediate rings can be connected to the corresponding hollow bodies of the respectively adjacent intermediate ring and thereby form the spacer elements. As a result, the possibilities just described are combined with one another in a structurally simplified manner.

Also according to an embodiment of the invention, it is provided that at least the spacer elements carrying the ring segments have an inward fold, so that each ring segment is displaced inward when the adjacent intermediate rings move axially. This design quickly creates space for tighter wound fibers.

Another embodiment of the invention in turn provides that the inner lateral surface of the winding carrier, with the exception of the end rings, at least partially has an oval cross section which extends in the direction of the first cutting plane. It is possible that certain spacer elements protrude inward beyond the inner circumferential surface when they are deformed, so that the winding tube would jam on the dye spear in such a case. The described quality in connection with the specially directed shape of the spacer elements creates the necessary space here without the guidance of the winding carrier being lost on the dye spear.

Another embodiment of the invention also provides that the spacer elements at least partially have predetermined kinks. As a result, the avoidance direction of the spacer elements can be predetermined while maintaining all previous advantages. The predetermined kinks can run in the direction of movement of the two mold jaws of the tool for the manufacture of the winding carrier, so that this measure also does not impair the manufacturability of the winding carrier according to the invention by a molding tool already described.

Furthermore, it is provided according to an embodiment of the invention that the spacer elements are straight, oblique, kinked, curved, C, O or S-shaped. All of these are shapes for the spacer elements with which a desired deformation behavior of the winding carrier can be achieved and which nevertheless allow the use of a two-jaw molding tool in the arrangement according to the invention for the production of the winding carrier.

It is also provided according to the invention that the elements forming the intermediate rings are straight, kinked, wavy and / or provided with predetermined kinks. These measures can also influence the deformation behavior of the winding support according to the invention in the desired manner without other advantages being lost.

It is further provided according to an embodiment of the invention that the body of the winding carrier on one side an end ring with an inner centering for a dye spear and an outer centering for a next end ring and on the other side an end ring with a centering for the outer centering of a preceding end ring. This measure also makes it possible, while maintaining all the other advantages, to align the individual winding carriers with respect to one another and to plug them together to form securely guided and aligned winding carrier columns, thereby facilitating a uniform coloring of the material being wound.

Another embodiment of the invention provides that all spacer elements are alternately rigid and soft in the axial sequence to the winding carrier. This is a particularly simple way of generating different deformation behavior zone by zone, without the demoldability during production being impaired by a two-jaw molding tool.

Another embodiment of the invention provides that all spacer elements of one plane lie with the spacer elements of adjacent planes in the same axial section planes. Such an arrangement relieves the intermediate rings and nevertheless makes it possible to build an axially rigid as well as an axially both soft and zone-wise winding carrier.

Furthermore, according to one embodiment of the invention, it is also proposed that a thread reserve groove is formed in at least one end ring. Such is already known in the prior art, and this thread reserve groove can advantageously also be molded in at the same time without problems, even in the case of a two-jaw molding tool.

Finally, it is also proposed according to the invention that the spacer elements have a width which decreases from the outside of the winding carrier, at least in their connecting region.

Winding cores, as they are known in the most varied of shapes and with the most varied deformation behavior in the prior art, can only be made from thermoplastics using molds that are adapted to their divisibility. In this way, however, it is possible to give the winding tube such a structure that a desired deformation behavior of the winding tube is achieved during its use. The necessary, very expensive molds are disadvantageous.

As described at the beginning, winding cores were also made with a four-jaw tool. As a result, the tool is already cheaper, but is still difficult to design because of the multiple separation for large quantities, because a separation into two levels must take place. In addition, such a simplified tool has only been used with a very simple winding tube.

With the features of the innovation, it is possible to achieve the most varied deformation behavior of the winding sleeve by means of a suitable construction, and nevertheless to produce the respective winding sleeve only with a two-jaw molding tool, which thus only has to be separated in one plane.

First of all, FIGS. 1 and 2 show a winding carrier that is rigid in the axial and radial directions. This winding support is constructed by a plurality of intermediate rings 32 arranged one above the other and delimiting planes 45, which are kept at a distance by spacing elements 7 arranged in planes 45. The spacer elements 7 are each arranged in the same axial section planes 47 and all aligned in the direction of these axial section planes 47, so that they have mutually aligned surface lines in this alignment direction. These spacer elements 7 are therefore all in planes 47 arranged parallel to one another, which subdivide the winding carrier in the manner of a disk in the axial direction. The surface lines 37 therefore lie in such a way that a molding tool (not shown in detail) can be separated in the first cutting plane 33 and can be moved together or moved apart perpendicularly to this first cutting plane 33, all spacer elements 7 extending with their surface lines 37 in the direction of the movement of the two molding jaws. With this construction, a jacket ring 36 is constructed by means of the end rings (not shown in detail) and the intermediate intermediate rings 32, which are kept at a distance via the spacer elements 7. However, the arrangement of the spacer elements 7 described leads to the jacket ring 36 having a free area on both sides next to the outermost spacer elements 7, which may be undesirable. It can be eliminated by means of spacer elements 8 and 9, which, however, are aligned in the direction of the first sectional plane 33, as can be seen in FIG. 2. Since these spacer elements 8 and 9 lie in this sectional plane 33, which at the same time represents the parting plane of the molding tool, the winding carrier remains manageable from a tool with a single parting plane, despite the changed arrangement of these spacer elements 8 and 9.

In addition, ring segments 31 can now be arranged parallel to the intermediate rings 32 for space adjustment and, if desired, for further support in the side regions mentioned, which are then held by the spacer elements 8 and 9 and the first adjacent spacer elements 7. The interior 35 of the casing ring 36 is filled by a so-called dye spear, which can use the inner casing surface 29 as a guide surface. To achieve the separability of the necessary mold in a single plane, namely the first cutting plane 33, it must always be ensured that the main directions of the alignment of the spacer elements 7 or 8 and 9 are rotated by 90 ° relative to one another, in the first cutting plane 33 only a single row of spacer elements 8 or 9 arranged exactly one below the other may be present, while the other spacer elements 7 pivoted by 90 ° to this end may all be arranged parallel to one another in this pivoted position, but may also be arranged offset to one another.

The last described variant is shown in FIGS. 3 and 4. 3 shows the winding support in the undeformed state. Here, too, the intermediate rings 32 are held at a distance from one another by spacer elements 10 aligned in the manner described, but these spacer elements 10 are arranged offset to one another in the circumferential direction of the winding support. In the first parting plane 33, which is not shown here, spacing elements 11 and 13 or 12 and 14 are alternately arranged with one another. Here, the spacer elements 11 and 12 are preferably rigid, as are the spacer elements 10, while the spacer elements 13 and 14 are deformable by an axial load. It is hereby achieved that in the case of an axial deformation, a radial deformation also necessarily occurs, as is shown in FIG. 4.

5 and 6 a variant of the embodiment according to FIGS. 1 and 2 is shown. The spacer elements 15 according to FIGS. 5 and 6 already have a pre-bent shape, which, however, runs on both sides of a plane of symmetry perpendicular to the first sectional plane 33 in opposite directions. This causes the spacer elements 15 to buckle when the winding support is axially deformed in a predetermined direction. Depending on the desired deformation behavior of the winding carrier, it is now possible to arrange spacer elements 17 in the first sectional plane 33 in the same orientation and deflection as the spacer elements 15. However, rigid spacer elements 16 can also be arranged there. Also in the embodiment according to FIGS. 5 and 6, the spacer elements 15, 16 or 17 are all located within the casing ring 36, and a so-called dye spear can also be arranged in the interior 35 of the casing ring 36. Here, too, it can clearly be seen that the surface lines 37 of the spacer elements 15 and 17 again run parallel to one another, in such a way that they run in the direction of the displacement movement of the two mold jaws of a molding tool which is separated in the first cutting plane 33. As an alternative to the spacer elements 17, spacer elements 16 can also be provided lying in the first sectional plane 33, the Mantelli of which lines 38 then run parallel to the first cutting plane 33, so that a separation of the tool for the production of the winding carrier is not disturbed in this plane.

In the embodiments according to FIGS. 7, 7a, 7b and 7c, completely different shapes of the spacer elements are shown, and it is shown that even such shapes can be handled perfectly with a tool that is only separated in one plane. Fig. 7 shows a winding carrier, the spacer elements 18 have the shape of cylindrical tube pieces which are placed between the intermediate rings 32 and whose orientation is such that the section line 39 of the planes of symmetry 40 and 41 of these spacer elements 18 again in the direction of the separating movement of the two mold jaws of the molding tool is arranged, in which case all these cutting lines 39 are arranged parallel to one another. In addition to this, as shown in FIG. 7 a, spacer elements 18 which are held flat in the first sectional plane 33 within the jacket ring 36 can also be provided. This combination can also achieve the desired deformation behavior of such a winding carrier in certain cases.

A supplementary variation is also shown in FIGS. 7b and 7c, in which the spacer elements 18 have inner surface lines 37 or outer surface lines 42 'which run in the direction previously described, while these spacer elements 18 according to FIGS. 7b and 7c have outer surface lines 42 or have inner surface lines 37 'which diverge towards one another in the direction of the interior 35 or the exterior 35' of the winding carrier. This makes it possible to achieve a greater resistance to deformation in the inner region than in the outer region, and yet separate mold jaws can only be used in one plane.

8 and 9 show that a winding carrier with an alternating cross-section of the body 1 can also be easily produced from mold jaws which can only be separated in a single plane. The diameter of the intermediate rings 32 ″ determine the cross-sectional profile of the body 1 of the winding carrier. In addition, an end ring 2 is formed on the body 1 in FIG. 8, which has both an inner centering 3 and an outer centering 4. With the inner centering 3, the body 1 can be centered on a dye spear, for example, and an end ring 5 is formed on the other end of the body 1 with an inner centering 6. The next body of this type, with its outer centering 4 of its end ring 2 then located at the bottom, can be positioned in this inner centering 6 of the end ring 5. It is then securely held and guided, and the end ring 5 can also have a thread reserve groove 46.

Furthermore, FIG. 8 shows a winding carrier which is equipped in an axial sequence with spacer elements of different types. These can be integrally formed on a single winding carrier, but they can also be present in a single version on a winding carrier. The spacer elements 18 ′ and 26 represent variants of spacer elements that can be deformed in the axial direction.

The arrangement shown further below has spacer elements 7 ″, which combine various intermediate rings in groups. The spacer elements 7 ″ are offset from one another in the circumferential direction. This arrangement enables axial mobility with forced radial mobility, but the winding carrier essentially only creeps into one another in its inner region, while its outer axial dimensions deform much less. Such behavior may also be desirable.

In a variant according to FIG. 10, open hollow bodies 34 in the form of, for example, tubular pieces are molded into the intermediate rings 32 ', but are kept at a distance in the first sectional plane 33 (not shown here), for example from axially rigid spacer elements 8' or 9 ' will. In the planes running perpendicular to the first sectional plane 33 and lying parallel to one another, rigid spacing elements 7 'are also provided in the axial direction, which are arranged one below the other in the exemplary embodiment according to FIG. 10. In the arrangement shown, it is possible to achieve radial deformability in one direction, while the direction perpendicular to it is radially rigid. In the exemplary embodiment, the axial direction is also rigid. However, it is possible to provide spacer elements of the type and shape and arrangement described so far in an exemplary embodiment according to FIG. 10, so that, for example, a two-stage deformability of the winding carrier can be achieved. It is then possible, if the originally intended deformability is not sufficient in the respective application, that the winding carrier additionally deforms, for example in a plane as described in FIG. 10, when a certain force is exceeded, so that damage to the wound material or an incorrect one Coloring can be prevented.

11 to 13 a similar embodiment is shown as already described for FIGS. 5 and 6. 11 to 13, the intermediate rings 32 are kept at a distance from spacer elements 19 and 20, respectively, which are pre-bent on both sides of a central plane and aligned in the manner described above, their deflections being directed toward one another on both sides of the plane described. In the outer edge region of the first sectional plane 33 are the spacer elements 21 and 22 which, together with the spacer elements 19 and 20 which are closest to the inside, carry the ring segments 31. An axial deformation of the winding carrier now causes the ring segments 31 to move radially inward, so that overall additional space is obtained after an axial deformation in the radial direction due to the radial inward movement of the ring segments 31, even though the intermediate rings 32 maintain their diameter. However, this causes the ring segment 31 to move radially inward, so that there must be sufficient space for the dye spear. This problem is eliminated in the embodiments according to FIGS. 11a-13a. There are the intermediate rings 32 with their inner ren opening oval (Fig. 13a), and the ring segment 31 is shaped accordingly, so that in the deformed state of the winding carrier inside a circle 48 approximately with the diameter of the dye spear, not shown.

14 and 15 show simplified forms of the winding support according to FIGS. 11 to 13, in which the ring segments 31 are missing. 15, spacer elements 25, 26, 27 and 28 are provided, which are preformed and provided with a predetermined kink 43. This results in a deformation of these spacer elements in a predetermined direction.

It has been shown with a large number of different exemplary embodiments that it is possible to design a winding carrier in such a way that all desired types of deformability can be achieved, and that nevertheless each of these winding carriers designed in this way is produced by a two-jaw molding tool, which is therefore merely is separable in a single plane, can be produced. It is crucial here that all elements for the construction of the winding support are aligned in such a way that they do not hinder the moving together and moving apart of two mold jaws of a molding tool. In this case, elements of the winding support may be formed in one another in the parting plane, and only in this one plane, the main extension of which is pivoted by 90 ° with respect to the main extent of the other elements, because the arrangement of such elements in the parting plane does not hinder the separation of the tool. All wishes for the deformability of such winding carriers can thus be met with a tool with only one parting plane for the mold jaws, so that it has been possible to propose shapes that can be produced with a very simple tool while maintaining all the desired advantages, thereby making it possible At the same time, it is now possible for the first time to design winding supports of various shapes for a wide variety of requirements, which can nevertheless be produced with a single or multiple two-jaw mold, because only a single parting plane is required. Although a large number of such winding carriers can be formed at the same time, the necessary molding tool remains relatively small and inexpensive.

11. Package carrier according to at least one of claims 1 to 10, characterised in that the intermediate rings (32") have different diameters in continuous succession and/or with periodic changes (Figures 8, 9).

12. Package carrier according to at least one of claims 1 to 11, characterised in that in the same direction as at least the spacer elements (7, 7', 10, 15, 17-20, 23-26) which are not associated with the first jointing plane (33), hollow members (34) open at at least the outer end are set at least into several inter- . mediate rings (32'), so that the intermediate rings (32') are interrupted in the peripheral direction by these hollow members (34).

13. Package carrier at least according to claim 12, characterised in that the hollow members interrupting the intermediate rings are connected to the corresponding hollow members of the respective adjacent intermediate rings and thereby form the spacer elements.

14. Package carrier at least according to claim 10, characterised in that at least the spacer elements (19, 22) carrying the ring segments (31) have an inwardly directed fold, so that each ring segment (31) is displaced inwardly upon an axial movement of the adjacent intermediate rings (32).

15. Package carrier according to at least one of claims 1 to 14, characterised in that the inner sleeve surface (30) of the package carrier, with the exception of the end rings, has at least in part an oval cross-section extending in the direction of the first jointing plane (33).

16. Package carrier according to at least one of claims 1 to 15, characterised in that the spacer elements (7-28, 7', 8', 9') have at least in part designated buckling regions.

17. Package carrier according to at least one of claims 1 to 16, characterised in that the spacer elements are rectilinear, inclined, collapsible, C-shaped, O-shaped or S-shaped.

18. Package carrier according to at least one of claims 1 to 17, characterised in that the elements constituting the intermediate rings are rectilinear, collapsible, undulating and/or are provided with predetermined buckling regions.

19. Package carrier according to at least one of claims 1 to 18, characterised in that the body (1) of the package carrier includes at one end an end ring (2) with an internal centering means (3) for a dye spear and with an external centering means for a succeeding end ring (5), and at the other end has an end ring (5) with a centering means (6) for the external centering means (4) of a preceding end ring (8).

20. Package carrier according to at least one of claims 1 to 19, characterised in that all spacer elements (7, 18', 26, Fig. 8) are alternately rigid and yielding in sequence axially of the package carrier.

21. Package carrier according to at least one of claims 1 to 20, characterised in that all spacer elements (7) in a plane (45) lie in the same axial sectional planes (47) as the spacer elements (7) of adjacent planes (45).

22. Package carrier according to at least one of claims 1 to 21, characterised in that a thread reserve groove (46) is provided at least on one end ring (5).

23. Package, carrier according to at least one of claims 1 to 22, characterised in that the spacer elements (19'), at least in their connecting regions (49, 50), have a width which is reduced as compared with their width at the outside (51) of the package carrier.
