Definitions

  • the present invention relates to a traversing element for a spinning machine, which serves for the production of roving, wherein the traversing element comprises a guide portion, by means of which the roving in the region of a surface of a sleeve or a roving bobbin is feasible, and wherein the traversing element comprises a support portion, over which it is connectable to a carrier of the spinning machine.
  • a spinning machine is proposed with at least one spinneret, by means of which a roving is produced from a fiber strand supplied to the spinneret, the spinning machine having a winding device for winding up the roving produced by the spinneret.
  • Generic traversing elements are known in connection with spinning machines and serve to guide the roving produced by the corresponding spinning station during winding onto a sleeve.
  • the respective traversing element is in this case in principle moved back and forth on a path running parallel to the axis of rotation of the sleeve between two end points, so that the roving finally reaches the sleeve in the form of superposed roving layers and the desired roving bobbin is formed (under the term "roving bobbin").
  • roving bobbin is to be understood in the context of the invention, a sleeve with roving wound on it).
  • Conventional traversing elements consist primarily of metal elements, which are heated by contact with the passing past the corresponding guide portion of the traversing element roving frictionally, which can lead to a negative effect on the roving properties.
  • Object of the present invention is therefore to propose a traversing element and a spinning machine equipped with it, which counteract this problem.
  • EP0857682 discloses a traversing element for a spinning machine, which serves for the production of roving, wherein the traversing element comprises a guide portion, by means of which the roving in the region of a surface of a sleeve or a roving bobbin is feasible, and wherein the traversing element comprises a support portion, over which it can be connected to a carrier of the spinning machine, wherein the traversing element comprises at least one closed to the outside cavity, which is partially filled with a liquid.
  • the roving produced by the spinning machine or guided by the traversing element is fundamentally a fiber composite, which is characterized in that an external part of the fibers (so-called binding fibers) is an inner, preferably untwisted Part of the fibers, wrapped around to give the roving the desired strength.
  • the roving has a relatively small proportion of Umwindemaschinen, the Umwindemaschinen are relatively loosely wrapped around the inner (preferably untwisted) core, so that the roving remains delayable. This is crucial if the produced roving on a subsequent textile machine (for example, a ring spinning machine) is to be distorted again with the help of a drafting system or must, in order to be further processed into a weave yarn.
  • the traversing element is characterized in that it has at least one outwardly closed cavity, which is partially filled with a liquid, wherein heat in the region of the guide portion by friction between the guide portion and the operation of the traversing element of the guide portion led roving arises, is absorbed by the liquid.
  • the heat does not build up in the area of the guide section. Rather, it is absorbed by the liquid and can eventually be removed to a location and discharged to the ambient air, which is not directly in contact with the roving.
  • the liquid may be various substances, such as water or ammonia.
  • the cavity should be only partially filled with the liquid to allow evaporation of the liquid in the area in which the heat is to be dissipated (preferably so in the region of the guide section or other standing in contact with the roving areas of the traversing element) ,
  • the liquid If the liquid is now heated by the heat absorbed, it begins to evaporate. Due to the resulting local pressure increase within the cavity the steam flows in a direction away from the heat source. As soon as the liquid vapor finally reaches a region of the cavity which is sufficiently spaced from the heat source, condensation of the vapor and the desired heat release into the ambient air occur. The liquid resulting from the condensation finally returns to the area of the heat source (ie the areas of the traversing element heated by friction with the roving), where it can absorb heat again, the return being by gravity (here we call it a "thermosyphon"). ) or by capillary forces ("heat pipe”) can take place (both variants can be realized within the scope of the invention).
  • the cavity should otherwise be elongate, so that the area in which the evaporation of the liquid takes place is sufficiently spaced from the area in which the vaporized liquid condenses again.
  • the cavity has a length which is between 10 cm and 40 cm.
  • the width i.e., the transverse dimension of the elongated cavity perpendicular to the longitudinal extent
  • the cavity has a cylindrical basic shape.
  • the support portion is formed as an elongated support arm.
  • the support section serves primarily to fasten the guide section, which may, for example, have an at least partially planar surface over which it is in contact with the roving.
  • the carrier portion of the bearing of the traversing element on a corresponding carrier of the spinning machine, wherein the carrier may be present, for example in the form of a trailing element fixing the holding element, which by means of a drive along a guide between two end points (preferably linear) back and forth, so that the carrier and the traversing element in the operation of the spinning machine to perform the desired traversing movement to guide the roving in the above manner when winding on a sleeve.
  • the cavity is at least partially disposed in the interior of the support arm.
  • the support arm itself could preferably form elongated cavity for the liquid.
  • the cavity containing the liquid at least partially extends within the support arm, so that not only the guide portion (which is preferably in the region of an end face of the support arm) can be cooled by the liquid. Rather, it is possible by the said formation of the cavity that the liquid contained therein also absorbs heat in a region which adjoins the guide portion in the longitudinal direction.
  • the support arm of the traversing element is wrapped one or more times during operation by the correspondingly guided roving to act on the roving prior to winding on the sleeve by friction with a certain tensile stress. If the cavity finally extends into the region which is wrapped around by the roving, the heat generated by friction between the roving and the support arm can also be absorbed by the liquid in this region and thus be led away from the roving.
  • the cavity is at least partially closed by a guiding element having the guide portion, so that the guide element forms a part of the cavity bounding wall.
  • the liquid gets particularly close to the guide section, so that a particularly efficient heat removal is made possible.
  • the cavity is enclosed, at least for the most part, preferably completely, by a tube wall of a heat pipe, wherein the heat pipe is arranged at least partially in the interior of the support arm and consists for example of metal.

  • a thermal compound is arranged to further improve the heat transfer from the pipe wall of the heat pipe to the wall of the support arm.
  • the heat pipe is in heat-conducting connection with the guide element, in particular in direct contact.
  • the heat arising in the region of the guide element as a result of the contact with the roving leading to it can therefore be absorbed by the liquid in a particularly efficient manner and removed accordingly.
  • the support arm has at least one end opening through which the heat pipe extends to the outside of the support arm.
  • the heat pipe can be directly cooled by the ambient air in the region located outside the support arm in order to effect the necessary condensation of the liquid vaporized by the heat absorption in the region of the guide element. It is also conceivable to couple the region of the heat pipe lying outside the support arm with a cooling element which will be described in more detail in order to further improve the cooling of the evaporated liquid in this area.
  • the heat pipe is detachably connected to the support arm.
  • the heat pipe which preferably has an elongated basic shape, can be detachably inserted into the support arm (for example, through the above-mentioned opening of the support arm and from a side facing away from the guide element).
  • the traversing element has a cooling element, wherein the cooling element preferably comprises one or more cooling fins, and wherein the cooling element is in heat-conducting connection with the guide portion.
  • the cooling fins could, for example, be disc-shaped and be aligned concentrically to each other or to a longitudinal axis of the traversing element or its support arm.
  • the cooling element should be arranged in the region of an end portion of the traversing element facing away from the guide section.
  • the support arm extends in this case between the cooling element and the guide element.
  • the support arm between the cooling element and guide portion during operation of the traversing element having spinning machine one or more times, as described above, entwined by the roving so can be done by said mutual arrangement of the individual sections a particularly efficient heat dissipation.
  • this ensures that the fluid present in the interior of the traversing element not only effects cooling of the guide element but also cooling of the area of the support arm which is looped around by the roving.
  • the temperature of all of the roving coming into contact portions of the traversing element is thereby kept at a relatively low level, so that a negative effect on the roving properties can be prevented.
  • cooling elements in particular one or more of said cooling fins
  • the cooling element (s) should preferably be placed in a region facing away from the guide section.
  • the cooling elements could project rib-shaped (in particular fan-shaped) from the rear side of the guide element facing away from the guide section to the outside.
  • the cooling element at least partially surrounds the heat pipe.
  • the heat from the inside of the heat pipe can be delivered in this case over a particularly large area to the cooling element, so that the evaporated liquid can be reliably condensed to heat again in the region of the guide portion or between the guide portion and the cooling element region of the traversing element to be able to record.
  • the cooling element is directly connected to the heat pipe in order to ensure a good heat transfer between the heat pipe and the cooling element.
  • the heat pipe can be placed in the end region of the traversing element facing away from the guide section and surround the heat pipe on the circumference and possibly also on the front side.
