Definitions

  • the invention relates to a dirt separator for carding devices or cards, which comprise a spool and carding segments interacting therewith, with a separating knife which has a blade section, the blade of which is arranged at a short distance from the surface of the spool against the running direction of the spool and with one hold-down devices arranged in the running direction of the drum in front of the discharge knife with a foot surface which runs essentially parallel to the surface of the drum.
  • Such a dirt separator is e.g. known from DE-A-2846109.
  • Such dirt separators are used in carding devices to remove the dirt particles still remaining in the fibers, as well as fiber fragments and shortened fibers.
  • part of the dirt particles to be separated often remains in the fibers and those fibers which are to remain in the processing process, so-called good fibers, are eliminated. Overall, this leads to unsatisfactory cleaning results.
  • the invention is therefore based on the object of developing a dirt separator of the type mentioned at the outset such that the ratio of dirt particles, fiber fragments and short fibers on the one hand to good fibers in the waste which is separated out is improved in such a way that the proportion of eliminated good fibers is reduced and the proportion in the excreted dirt particles increases.
  • the blade viewed in cross section, has at least one rounded section with a radius greater than 1 mm.
  • the radius is between 1 and 5 mm and the excretion knife is designed as an essentially plate-shaped structure with a contact side for attachment to a carding segment and a front side parallel thereto and that the excretion knife extends essentially over the entire length Width of the spool extends.
  • the blade can furthermore have a front side arranged opposite to the running direction of the drum and a back side arranged in the running direction of the drum, wherein the front and the back side can be connected to one another by the rounded section.
  • the front and the back can enclose an angle of approx. 70 °.
  • the front can extend parallel to the planar extent of the knockout knife.
  • the front side can be inclined by approximately 10 ° with respect to the planar extension of the discharge knife.
  • the cleaning result can be increased by tangentially merging the front and back of the blade into the rounded section.
  • the back of the blade lies in an imaginary plane that encloses an angle of approximately 10 ° with a plumb plane for the planar extension of the separating knife.
  • the radius of the rounded section can essentially correspond to the thickness of the discharge knife.
  • the front of the blade and the front disc of the knockout knife can be in one plane.
  • the thickness of the discharge knife in the area of the blade can be significantly less than in the other areas of the discharge knife.
  • a section inclined in the opposite direction can follow the front which is inclined by approximately 10 ° with respect to the planar extension of the separating knife, wherein the front and the inclined section can form a recess in the separating knife.
  • a plurality of depressions can also be arranged in a wave shape one behind the other on the discharge knife.
  • the distance between the blade and the surface of the drum can be changeable.
  • At least one supply air duct can be provided according to the invention, with at least one opening, which is arranged opposite the direction of travel of the drum in front of the foot surface of the hold-down device, in such a way that an air flow guided through the supply air duct passes through the opening in the direction of the surface of the drum
  • the opening can be arranged near the surface of the drum.
  • the supply air duct can also be limited by a carding segment and the hold-down device.
  • the hold-down device can have a fastening section and an adjoining foot section, which foot section carries the foot surface on its side facing the drum, and the fastening section, together with the carding segment, delimits the supply air duct.
  • the fastening section of the hold-down device can be spaced from the carding segment, the distance between the carding segment and fastening section being adjustable in such a way that the cross section of the supply air duct can be changed.
  • the cross section of the supply air duct can be essentially rectangular. A width of approx. 10 mm has been found to be optimal during operation.
  • the cross section of the supply air duct is normally constant over its length, but it is also conceivable that the supply air duct tapers in the direction of the drum surface.
  • a supply air regulator can be provided with which the air flow passing through the supply air duct can be regulated.
  • the supply air controller preferably has a tongue which can be moved into the supply air duct in such a way that the cross section of the supply air duct can be changed.
  • the tongue can have an end section which is bent in relation to the flat expansion of the supply air regulator in such a way that it projects into the supply air duct.
  • the supply air controller like the supply air duct, advantageously extends over the entire width of the reel.
  • the distance between the foot surface of the hold-down device and the drum can be adjustable.
  • the distance can be set to zero, with no more dirt separation.
  • a distance of 0.25 to 25 mm has been found to be a favorable distance between the foot surface and the drum for the operation of the dirt separator.
  • the gap formed between the foot surface and the drum tapers in the running direction of the drum.
  • the foot surface of the hold-down device can have a concavity which points away from the surface of the drum. It has been shown that this curvature brings about an improved dirt removal result. In this context, it has proven to be advantageous if the foot section of the hold-down device has an end section facing the knife, the end of which runs essentially perpendicular to and away from the surface of the reel.
  • the clear width between the foot surface and the blade section can be changed.
  • the clear width can be reduced to zero with no more dirt being removed.
  • the hold-down can also extend across the entire width of the reel.
  • the hold-down device is bent from a material whose thickness is significantly less than its planar extent. On the one hand, this allows low production costs, and on the other hand, a cavity can be formed between the hold-down device and the knock-out knife, which can be used to receive suction for the fibers or dirt particles that have been separated.
  • a cover is provided between the separating knife and hold-down device to form a suction chamber closed by the hold-down device, the separating knife and the cover. In this way, the separated dirt particles can be supplied via the suction chamber and a suction device in a receiving device provided for holding the dirt particles.
  • Fig. 1 shows a schematic representation of a Kadiervorraum 1 with a drum-shaped reel 2 with running direction 1, as well as feed rollers 3 and 4 for feeding a fiber material 5 and a unwinding roller 6 for removing the carded fiber material 5 from the reel 2.
  • the reel 2 has an axis 7.
  • the Kadiervortechnik has a frame 8, which is, however, only partially shown here for the sake of clarity. In addition to accommodating drive motors, the frame 8 also serves to support the reel 2, the feed rollers 3 and 4 and the unwinding roller 6.
  • Assembly devices 9 for fastening carding segments 10 can also be seen in FIG. 1.
  • the mounting devices 9 are arch-shaped and are arranged in a stationary manner near the drum, near the end face thereof.
