Definitions

  • the invention relates to a Unterriemchen exchange for a Doppelriemchenstrecktechnik with a lower roller and a deflector looping Unterriemchen, wherein the deflecting element is substantially parallel to the axial direction of the lower roller and the Unterriemchen ausaubar, and wherein means for positional positioning of the deflecting element are provided, which in a replacement of the Deflection element ensure positioning in a predetermined desired position.
  • a Unterriemchen entry this type is the German Patent Application 1 510 589 prior art.
  • the deflector is supported via two wall parts on the lower roller.
  • the deflector is made with one of the wall parts in one piece and is connected to the other wall part via a plug connection.
  • the deflection element for the Unterriemchen is connected to the Oberriemchen hofig via a second connector.
  • the connection to the Oberri ⁇ mchen hofig defines the height position of the deflecting element in relation to the stretching field plane. After releasing the two connectors, the deflecting element can be pulled parallel to the axial direction of the lower roller from the Unterriemchen. The Unterriemchen thereby remains in its original position.
  • the known Unterriemchen entry has the advantage that the connectors allow easy removal and installation by untrained personnel. An expansion of Unterriemchen Entry is required, for example, for cleaning purposes, since it can come during operation to Schmutzstromrungen in the Unterriemchen Unit. The deflector of Unterriemchen Installation comes through the connectors during installation automatically in its specified nominal position. There are no time-consuming adjustments for a Bachubba ⁇ necessary.
  • the invention is based on the object, while maintaining the advantages of the known Unterriemchen operation, to create a Unterriemchen arrangement that allows tolerance compensation in particular the differences in diameter of the Unterriemchen from spinning station to spinning station.
  • the object is achieved in that the means for position positioning have an adjustable desired position.
  • the position of the deflecting element can be adjusted separately for each individual Unterriemchen.
  • Each loop may be adjusted so that the tension in the bottom apron reaches a desired height regardless of the tolerances and diameter differences of the bottom apron. No separate tensioning device is required for the lower apron.
  • the height position of the deflecting element with respect to the plug plane in a change of the spun fiber material without replacing the complete of the Unterriemchen arrangement done is not adjusted directly, but at the means for position positioning another target position is set, the said advantage is obtained, that the deflecting again takes exactly the same position during replacement after removal. There are no Ei ⁇ stellin required if the deflection was removed, for example, for cleaning purposes.
  • the position-positioning means contain an adapter.
  • the adapter can be advantageously mounted adjustable to the lower roller on a fixed frame part of the drafting system. In this way, in particular those height positions can be achieved in which the upper edge of the deflecting element is located above the stretching field plane.
  • the adapter in turn holds the deflecting element.
  • the position of the deflecting element can be ensured for example by plug connection elements between the adapter and deflection.
  • the fasteners such as screws or bayonet locks, between adapter and frame part of the drafting system, as well as between adapter and deflector r are separately solvable.
  • the deflection of the adapter is solvable without changing the desired position.
  • the deflecting element When installing a new Unterriemchens at a spinning position, the deflecting element is connected to a means for Siegposjtion réelle, such as an adapter.
  • the means for positioning is now adjusted so that the Unterriemchen having the desired .Connect voltage erkoritru ⁇ d "that Däs ⁇ deflection ⁇ eemperent.
  • the desired position in relation to the lower roll and with respect to the Streckfeldeb ⁇ ne.
  • the means for positioning the deflecting element that is, for example, the adapter is now fixed in its adjusted position, for example by screwing it to a frame part of the drafting system, thus fixing the deflecting element in its desired nominal position and allowing the drafting operation to take place.
  • the deflecting without changing the desired position against a deflecting element with different guide geometry, preferably on the side facing the fiber strand is interchangeable.
  • the set target position of the position-positioning means in particular the adapter, can be exploited to increase the flexibility of the Doppelriemchen-drafting system.
  • a plurality of deflection elements can be provided with different guide geometries, which are alternately fastened to the means for positional positioning, and which can be used without readjusting the desired position with the same Unterriemchen. It is thereby possible, for example, in a lot change, even a large number of Doppelriemchen drafting systems very easy to convert to Unterriemchen exiten with different leadership geometry.
  • FIG. 1 shows a side view of a double apron drafting system with a lower apron guide according to the invention
  • FIG. 2 shows a top view in the direction of the arrow II of FIG. 1 on the lower apron guide, wherein the upper rolls and the upper apron have been omitted for the sake of clarity
