Definitions

  • the invention relates to a device for storing thread-like material which can be pulled off a supply spool, e.g. Weft yarn, wire, ribbon etc., in particular on a weaving machine, with a winding body, which has a supporting part arranged around an axis of rotation and a substantially cylindrical winding drum arranged thereon and having a central axis, as well as a number of circumferential elements radially adjustable to the winding drum for guiding the contains thread-like material that can be stored in a single-layer winding on the circumference of the winding body and can be pulled off the winding body in the axial direction.
  • a supply spool e.g. Weft yarn, wire, ribbon etc.
  • the winding drum is mounted eccentrically with respect to the axis of rotation in the edge region of a support disk which is rotatable about the axis of rotation or, in another embodiment, secured against rotation.
  • Different winding diameters can be set in accordance with the respective radial position of the peripheral elements, which each determine a polygonal to approximately circular guideway for the thread-like material to be stored with a peripheral portion of the winding drum.
  • the one corresponding to the largest winding diameter runs Guide track essentially concentric to the axis of rotation, while the guide tracks corresponding to the smaller winding diameters run eccentrically to the axis of rotation.
  • the increasing eccentricity of the thread winding in accordance with the decreasing winding diameter can lead to discontinuous stresses and thus to voltage fluctuations in the section of the thread-like material running from the supply reel to the winding former, particularly in the case of the small winding diameters.
  • the invention has for its object to provide an improved in this respect, further developed device of the type mentioned, which allows a continuous, gentle removal of the thread-like material from the supply spool.
  • winding drum is fastened to the support part so as to be adjustable transversely to the axis of rotation.
  • the peripheral elements in each position of the winding drum that is eccentric with respect to the axis of rotation, can each be set in a radial position relative to the winding drum in which their peripheral parts with respect to the central axis of the winding drum, which lie in a plane perpendicular to the central axis, and the In the same plane, circumferential part of the winding drum lying furthest away from the axis of rotation, determine a circumscribed circle concentric to the axis of rotation, the diameter of which can be freely adjusted between the limits given by the corresponding dimensions of the supporting part and the winding drum.
  • This arrangement ensures for all winding diameters an essentially constant, particularly low stress on the thread material and is therefore particularly suitable for processing delicate thread material.
  • the winding drum can be pivotably articulated on the support part about a pivot axis arranged offset with respect to the axis of rotation and with respect to the central axis of the winding drum and can be fastened adjustably about this pivot axis.
  • the pivot axis of the winding drum is offset by the same amount with respect to its central axis and with respect to the axis of rotation.
  • the winding drum alone can also be adjusted concentrically to the axis of rotation of the winding body without using circumferential elements, so that even with the smallest winding diameter of the winding body given by the diameter of the winding drum, the winding of the filamentary material to be stored is ensured with essentially constant tension.
  • a device in a particularly compact, reliable construction can be achieved in a further embodiment of the invention by providing at least two holding parts which are offset against one another on the end face of the winding drum and act against one another around the central axis thereof and can be braced against the supporting part.
  • the winding diameter of the winding body can be adjusted in a particularly simple manner and also continuously over the entire adjustment range in that the support part contains at least two guide slots formed on its end face facing the winding drum for guiding one of the holding parts each.
  • the setting of the winding diameter can be facilitated by the fact that the guide slots are formed in a circular arc and are arranged concentrically to the pivot axis of the winding drum.
  • the guide elements can be positioned opposite one another in the winding drum the axis of rotation of the winding body offset shaft can be driven, which is connected to a drive shaft determining the axis of rotation of the winding body adjustable relative to this.
  • a particularly compact design with a relatively small dimension of the device in the axial direction can thereby be achieved according to one embodiment of the invention be that the support part on its end facing the winding drum contains a recess corresponding to the range of motion of the rotating body adjustable with the winding drum, which is suitable for receiving a section of the peripheral part of the rotating body which can be inserted into the area of the supporting part.
