Definitions

  • the object of the invention is to create an easily adjustable storage system that avoids the shingling effect.
  • the invention provides a device according to claim 1 and a method according to claim 6.
  • the invention is initially based on Fig. 1 described.
  • An opening or chopping roller 1) delivers fibers / flakes, which are chopped off at a knife 2), into a shaft which is formed on two sides by sieve belts 3).
  • a fill level monitor 9) prevents overfilling of the shaft and can influence the fill quantity.
  • the falling fibers are compressed by the rotating sieve belts 3).
  • Suctions 4) are provided so that the fibers do not slip through the sieve belts and dust escapes.
  • the distance between the sieve belts can be adjusted at the outlet 10).
  • the angle a) that the sieve surfaces of the sieve belts occupy on the suction side to the fiber transport direction can be between 0 ° and 30 °.
  • the sieve belts form two sides of a chute that is parallel or tapering in the direction of material flow.
  • a suction 4) is assigned to each sieve belt 3) in such a way that the suction 4) extends along at least a section of the sieve belt 3) running vertically or at the angle mentioned in the area of the shaft.
  • the suction 4) is provided on the side of the sieve belt 3) facing away from the fiber flow and thus generates a suction air flow through the sieve belt 3), which sucks the fibers onto the sieve belt 3) and sucks dust and the like through the sieve belt 3).
  • the two sides of the discharge chute not formed by sieve belts are formed by wedge-shaped walls, preferably made of transparent plastic. This creates an angle ⁇ ).
  • the belts can be provided with an automatic internal and external cleaning system.
  • the belts are driven by gear motors, preferably on an upper roller 5).
  • the belt speed of the main belts 3) is a maximum of 20% slower than the speed of the discharge belt 8). In order to additionally compact the mat, it can also be up to 100% faster.
  • the deflection roller 7) or 11) around which the formed fiber mat is deflected and carried away by the discharge conveyor 8) should have a greater distance from the discharge conveyor than the other of the two.
  • the Figure 2 shows a corresponding embodiment in which the deflection roller 7), around which the formed fiber mat is deflected and carried away by the discharge conveyor belt 8), has a greater distance from the discharge conveyor belt than the deflection roller 11). Otherwise, the embodiment is according to Figure 2 identical to that according to Figure 1 .
