Definitions

  • the present invention relates to a method for treating fiber flakes, in which fiber flakes are continuously introduced at an entry point into a deposition shaft by means of a first air stream, and in which introduced fiber material is continuously removed from the deposition shaft at an exit point.
  • German patent specification No. 1 286 436 and from Swiss patent specification No. 599 362 to supply fiber flakes to a deposit shaft by means of transport air and to deposit them there.
  • the shaft is provided with a slotted side wall. This enables the transport air, which has to be moved, to escape through the slots.
  • fiber accumulations occur at various points, e.g. in the blow room, on the cards, on the lines, on the combing machines, etc.
  • This so-called “exit” is presented in Fiber flakes of various shapes. So that it can be used again, it must be in a suitable flake form. Such flakes can be recycled, for example, by mixing them with fresh flake material.
  • the present invention is used to form fiber flakes of such a suitable flake shape and is characterized in that the fiber material removed again from the deposition shaft is again broken down into flakes, that these flakes are transported further by means of a second air stream, and that the flakes caused by the first air stream transport air moving away from the deposit shaft is used again to form the second air stream.
  • the air transporting the flakes to the deposit shaft is led outside. It should be noted that such transport air is associated with costs: the energy required to move it must be used. In addition, the outside air must be cleaned; as a result of today's regulations, achieving the prescribed level of purity is costly.
  • the aim of the invention is to keep the costs of the air flows transporting the flakes relatively low.
  • the invention also relates to a device for performing the method.
  • This has the deposit shaft, which comprises a first compartment for the fiber flakes introduced and a second compartment for the air emerging from the first compartment, separated by an air-permeable wall, and also has a first pneumatic transport line leading to the first compartment for transport of the fiber flakes.
  • the device is characterized by a flocculation device located at the exit point on the deposit chute, by a second pneumatic transport line leading away from the flocculation device for transporting fiber flocks and by a bypass leading from the second compartment of the deposit chute to the second transport line for the exiting from the second compartment. Transport air supplied by the first transport line.
  • the figure shows a first, pneumatic transport line 11, which is used to transport fiber flakes. Following this, a deposit shaft 12 is provided. This consists of a first compartment 13 and one of these through an air-permeable wall 14 separate, second compartment 15. The first compartment 13 contains fiber material 16 introduced therein.
  • a flocculation device is provided below the shaft 12. It consists of a feed roller 17, a pressing trough 18 arranged next to it and an opening roller 19. The latter is equipped with pins 20 distributed over its outer surface.
  • a second pneumatic transport line 22 serves to lead away the fiber flakes formed by the flaking device 17, 18, 19.
  • fiber flakes are introduced into the first compartment 13 at an entry point 26 by a first air stream flowing through the first transport line 11 in the direction of the arrow shown.
  • the transport air brought in by the first air stream flows through the air-permeable wall 14 into the second compartment 15, as is again shown by arrows.
  • the flake material 16 deposited in the shaft 12 or compartment 13 is detected at an exit point 27 and moved through between the roller 17 and the pressing trough 18. This forms a fiber beard 23.
  • the pins 20 of the counterclockwise rotating opening roller 19 tear away from the fiber beard 23 fibers in the form of fiber flakes.
  • the transport air entering the second compartment 15 is not conducted outside, but is supplied to the second pneumatic transport line 22 via a diversion 21. Through this air and through the second air flow flowing in line 22 the flakes formed by means 17, 18, 19 are transported to their next processing stage.
  • the provision of the diversion 21 conveys the advantages mentioned at the outset, namely only a slight slowdown in the flowing transport air and the elimination of the need to clean the air transporting the flakes into the deposit shaft 12.
  • the deposit shaft 12 has a horizontal, i.e. plane perpendicular to the drawing plane, a rectangular cross section.
  • the first compartment 13 and the second compartment 15 also have a rectangular, horizontal cross section.
  • the back of the trough 18 forms part of the wall of the diversion 21, which means simplifying and reducing the cost of the device.
  • a suction device 28 of variable suction power can be provided on the second transport line 22 in a special embodiment of the invention. If the amount of air coming from the line 11 or the second compartment 15 is too small for the line 22, the diversion 21 can be provided with an opening 24 for false air, ie for air flowing in from outside, in a further embodiment of the invention. In the figure, an opening 24 is shown, the size of which can be adjusted by a slide 25.
