Definitions

  • the invention relates to a winding support for receiving yarns, with a rotationally symmetrical body that forms a wing supporting the yarn, the body being provided at both ends with an annular toothing, the teeth of which protrude in the axial direction and the radially outer ones Surfaces connect continuously to the wing and have the same diameter among each other, and the teeth of one toothing are each adapted to the interdental spaces of the other toothing.
  • winding carriers axially one above the other after they have been provided with a yarn package. In this way, the storage and / or transport space required for the wound winding carrier is reduced. Furthermore, it is known to arrange such winding carriers guided axially one above the other by a dye spear or a dyeing spindle for the purpose of treating the yarn winding with a treatment medium, in particular for dyeing.
  • the coils carried by the individual winding carriers are pressed together to form a yarn column that is as homogeneous as possible with the aim of maintaining the same flow conditions for the treatment medium over the entire height of this column.
  • Winding supports are known in which the supporting surface provided for receiving the yarn is delimited at least at one end of the winding support by a closed end ring which extends radially relative to the supporting surface protrudes outside.
  • winding carriers now e.g. are placed axially one above the other for dyeing, so initially only the winding carriers come into contact with one another, while a considerable annular space remains free between the windings of adjacent carriers.
  • the protruding ends of the bobbin must first be shifted against each other, with the yarn being displaced on the bobbin and the ends of the bobbin being pressed into the bobbin. Disturbances in the specified course of yarn are the result, e.g. can have a negative impact on unwinding.
  • winding carriers DE-PS 851 946
  • DE-PS 851 946 have a perforated sleeve jacket and at the ends of the projections and gaps arranged essentially in the sleeve jacket surface, which are suitable, tooth-like in corresponding gaps provided at the ends of adjacent coaxial carrier and To engage projections axially slidably.
  • the disadvantage of these known winding carriers is that they are not axially guided against one another and that they also do not permit secure accommodation of a thread reserve.
  • winding carrier known (EP-OS 201 826), in which an upper end ring is provided with an axially projecting collar, which can be inserted into the lower end ring of an axially adjacent, identically designed winding carrier and thereby space for one on the collar provided thread reserve, which is thus housed protected.
  • the extent to which the waistband of one winding carrier can be inserted into another is limited by shoulders and shoulders.
  • a thrust ring surface is provided which is offset radially outward with respect to the support surface.
  • the object of the present invention is to provide a bobbin of the type mentioned in such a way that a thread reserve can be safely accommodated and that immediately after such bobbins are axially stacked, the bobbins thereon come into contact with one another, so that in the case of axial pressing not only the winding carriers have to be moved first, but that the windings are always compressed together with the winding carriers.
  • the winding can be carried out up to and in the area of the two toothings cover, for example, 50% of their axial extent. This leaves a gap of about 2 to 4 millimeters for the gears. If such wound bobbin carriers are placed axially one above the other, the toothings bring about mutual centering. In addition, the end faces of the adjacent windings come to lie directly against one another. This saves storage and transport space. Furthermore, it is ensured that, in the event of an axial compression, this pressure also becomes effective between the windings, so that relative movements between the windings on the one hand and the winding carriers on the other hand are practically eliminated.
  • the two toothings of a winding carrier are adapted to one another to enable insertion into one another, but their contours may well differ from one another.
  • the supporting surface of the winding support according to the invention can be cylindrical, conical or otherwise and can be continuously merged into the outer surfaces of the toothings. There is no restriction regarding the type of wrapping to be used.
  • the collar improves the guidance between two axially adjacent winding carriers. It can also be used to accommodate a thread reserve.
  • the winding support according to the invention can also be designed so that the receptacle has a stop shoulder for the end of the collar of an axially adjacent winding support. This stop shoulder defines exactly the extent to which two adjacent winding carriers can be inserted into one another without pressing.
  • the winding support according to the invention can also be designed so that a thread reserve groove is provided on the collar. In this way, the placement of a thread reserve be further secured.
  • the winding carrier according to the invention can also be designed in such a way that the two toothings have undulating tooth profiles. When using such a tooth profile, the teeth of adjacent winding carriers automatically lead into each other.
  • the winding support according to the invention can also be designed so that the two toothings have sawtooth-like tooth profiles.
  • the winding carrier according to the invention can also be designed such that the two toothings have essentially rectangular tooth profiles.
  • the winding carrier according to the invention can also be designed such that the teeth of at least one toothing have at least one support section which only makes up part of the respective tooth profile for contacting the teeth of an axially adjacent identical winding carrier. This is particularly advantageous if the insertion of adjacent winding carriers is limited by the tooth engagement, not by a stop shoulder. A jamming is then also excluded.
  • the winding support shown in Fig. 1 has a rotationally symmetrical body 1, which is only shown schematically and the formation of which is not the subject of the invention.
  • the body 1 can be in one or more parts and have a cylindrical, conical or other shape.
  • the body 1 forms an airfoil 2, which can be formed by webs or by a preferably perforated jacket wall.
  • a lower toothing 3 and an upper toothing 4 are connected to the wing 2.
  • Both toothings 3, 4 are ring-shaped and have equidistantly distributed teeth 5, 6, each of which protrude axially.
  • the radially outer surfaces of the teeth 5, 6 connect continuously to the wing 2.
  • the outer diameters of the two annular toothings 3, 4 are identical to one another.
  • a collar 7 is provided which projects beyond the upper toothing 4 in the axial direction.
  • the collar 7 has an outer surface 8 which is offset radially inwards relative to the upper toothing 4.
  • the teeth 6 can thus be understood as lying on the outer surface 8 of the collar 7.
  • a receptacle 9 is provided, the diameter of which is adapted to the outer diameter of the collar 7.
  • the receptacle 9 forms a stop shoulder 10.
  • both toothings 3, 4 have an undulating profile.
  • FIG. 2 shows three winding carriers of the type described in FIG. 1 with windings 11, which are assembled into a yarn column 12.
  • Fig. 2 makes it clear that the end faces of the winding 11 are each in the central region of the two toothings 3, 4. Because of the adaptation between the lower toothing 3 and the upper toothing 4, such winding carriers can be placed axially one above the other, the teeth 5, 6 engaging with one another and the collar 7 engaging in the receptacle 9, where it finally strikes the stop shoulder 10. If the coils 11 assembled according to FIG. 2 are to be axially compressed, then pressing immediately results in the winding carriers and the coils 11 being compressed, since there is practically no gap between the coils 11 after the winding carriers have been placed on top of one another.
  • Fig. 3 illustrates on a larger scale the interlocking of adjacent winding carriers.
  • the diameter of the outer surface 8 of the collar 7 projecting beyond the teeth 6 is smaller than the inner diameter of the receptacle 9, so that a thread reserve can be accommodated on the outer surface 8 in a protected manner.
  • the placement of the Thread reserve can be further secured in that a thread reserve groove is provided in the outer surface 8, as indicated by dashed lines in FIG.
  • tooth profile shapes are shown, which among other things. can be used in the winding carrier according to the invention.
  • the tooth profiles according to FIGS. 4 and 5 are sawtooth-like profiles that only differ in the design of their tips.
  • Fig. 6 shows a tooth profile which is rectangular.
  • the toothing 13 is profiled in a wave shape.
  • the toothing 14 has teeth 15 which have support sections 16 which only make up part of the entire tooth profile and define how far the toothings 13, 14 can be guided into one another.
  • the teeth of all the described embodiments are rounded in particular at their front ends, in order to pass under the winding 11 located on the other winding support in order to avoid damage to the yarn.
