Definitions

  • the present invention relates to an arrangement according to the preamble of patent claim 1.
  • the fiber flakes fly away from the opening roller at high speed.
  • the fiber material is often accumulated in the shaft in an unsuitable state for further processing.
  • it is generally not homogeneous in its density, so that fiber regions of different densities are present in the filling shaft.
  • this disadvantage should be avoided.
  • This is defined by the features present in the characterizing part of claim 1. This slows down the fiber flakes immediately after they have left the opening roller. In addition, the air flow between the opening roller and the filling shaft is influenced. The fiber flakes lose a significant part of their kinetic energy, so that they sink relatively gently to the ground and are evenly distributed over the entire cross-section of the shaft. In addition, the turbulence in the area of the filling shaft is reduced.
  • the invention will now be explained in more detail using an exemplary embodiment and the drawing.
  • the latter shows a cross section of the upper end of a filling shaft and a beater or opening roller arranged thereon.
  • the fiber material is fed into a feed channel 1 and arrives at feed rollers 2 which are rotatable in the direction of rotation indicated by the arrows 3.
  • An opener or beater roller 4 is provided below the feed rollers 2. This can be rotated in the direction of the pillar 5. Tips 6 are attached to their lateral surface.
  • a filling chute 7 is located below the roller 4.
  • a deflection element 8 is pivotable about a pivot axis 9.
  • the element 8 covers the area of the fiber material flying away from the roller 4. It forms a surface element 10 which is adapted to the curvature of the lateral surface of the opening roller 4.
  • the opening roller 4 rotates at high speed.
  • the rollers 2 move fiber material against the roller 4.
  • the tips 6 of this fiber material are continuously torn away as loose fiber flakes of various sizes or as dissolved fibers and conveyed into the shaft 7. Because of the high speed of this torn-away material, there is a tendency for the flakes in the filling shaft 7 to fly to the same places. As a result, the fiber material is distributed inhomogeneously in the shaft 7 and regions of different densities are formed. This is disadvantageous for the further processing of the same.
  • the curved surface element 10 primarily causes the fibers to be deflected from their trajectory, which was given to them by the roller 4. As a result, they lose kinetic energy, depending on the pivoting position of the deflecting element 8. If one directs the trajectory of the flakes flying away from the element 8 against the inside of the wall opposite the deflecting element 8, shown in the drawing as the right side of the shaft 7, then a loss of kinetic energy occurs again upon impact. As a result of the effect of the element 8, the air flow generated by the opening roller 4 and directed into the shaft 7 is also influenced. This will make the fiber flakes. strongly mixed before touching down and also sink down in a calm movement.
  • the braking of the fiber material after its detachment from the roller 4 can be varied as desired by suitably adjusting the pivoting position of the deflecting element 8 and the impact element 12, which is designed as a plate in the example shown.
  • the deflecting element 8 and the impact element 12 can be pivoted and adjusted as desired between the positions shown in broken lines.
