Definitions

  • the present invention relates to a method and a device for removing dust, waste and short fibers in the departure zone of a card or card, which has a take-off roll or doffer, a customer an upper and a lower nip roll, and a transverse conveyor belt.
  • Carding and carding are used to clean and open cotton or other fiber. These cleaning steps release a lot of dust, short fibers and other waste that accumulates in the card. When these partially flocked agglomerates of dust and short fibers are dragged back from the nonwoven or sliver, this causes an impurity or thick spot in the end product of the card or card. These are extremely undesirable effects and lead, for example, to an impairment of the downstream spinning process.
  • a non-woven fabric is formed which is brought together by the transverse conveyor belt to form a sliver.
  • the fibers are handed over several times from roller to roller whereby there are spaces through appropriate arrangements of the rollers, in which the pollution can accumulate with preference.
  • the small air movements that arise in particular by the squeezing rollers in these spaces circular air movements, which also have an adverse effect on the removal of this pollution.
  • this accumulation of particles is most often a problem.
  • the degree of soiling in these rooms depends on the material to be processed, the production volume, the degree of contamination of the raw material and the cleaning efficiency of the preceding cleaning processes as well as general conditions such as temperature and relative humidity in the production plant.
  • the dust and short fibers With high levels of water vapor in the air, the dust and short fibers will tend to develop sticky properties and accumulate in areas where there is no airflow. By contrast, with a relatively low water vapor content, the dust and the short fibers tend to remain isolated and accumulate in circular air currents.
  • a solution according to the invention provides a compressed air device for generating a predetermined air flow in the area between the take-off roll, the take-off and the squeeze rolls.
  • the compressed air device is arranged in the region between the take-off roll, the pick-up and the squeegee so that the air flow blows through the opening gap between the lower squeegee and take-off roll.
  • the airflow should be guided so that it does not disturb or impair the normal course of the fleece removal.
  • the invention differs from devices such as US 3,235,911 A in which an air flow is used to support the fleece removal.
  • the duration of the generated air flow is adjustable.
  • the compressed air device may then optionally generate a continuous stream of air or operate at intervals, for example at intervals of 1 to 60 minutes, advantageously 3 to 30 minutes, producing a burst of air for a duration of up to 60 seconds, advantageously up to 10 seconds. It would be advantageous if the interval sequence and / or intensity is set and / or controlled by the controller, for example with an adjustable and / or controllable solenoid valve.
  • the compressed air device is advantageously integrated in a non-woven baffle or Vliesleit Kunststoff, if they are present. But this integration should take place without affecting or impairing the function of the nonwoven guide plate or the Vliesleitmaschine.
  • the compressed air device can be made of any suitable material, advantageously from a hollow profile of chromium steel or aluminum, possibly anodized.
  • the profile can optionally be provided with at least one slot or hole in the suitable area. Combinations of slit-shaped, oval or round openings are conceivable.
  • the choice of shape and the number of holes depends on the working width of the entire compressed air profile and the number of feed positions for the compressed air supply in the profile.
  • An example of a solution according to the invention is an arrangement in a line of several round holes in the case of an infeed at the head or foot of the compressed air device.
  • the holes can also be arranged in a pattern or staggered.
  • a Abfallleitblech attached, which transports the dirt particles outside the carding board, where they are disposed of during normal soil cleaning.
  • the construction of the Abfallleitblechs can be made of any suitable material, advantageously made of chromium steel or aluminum, possibly anodized.
  • a dirt-repellent treatment of the surface of the material, for example a sliding layer, can additionally improve the dirt removal.
  • One solution would be the arrangement of a suction device below the gap. This suction device can be coupled to the already existing central suction device of the card. As a result, the dirt is fed to a filter system. For the space between the squeeze roller and the transverse conveyor belt, the solution to the removal of the accumulated material is rather the arrangement of one or more suction devices.
  • the sliver outlet may be located in the middle or on the side; the partial suction device therefore also in the middle or on the side.
  • the suction device for the space above the upper doctor blade and the transverse belt device is formed by a suction funnel, whereby the dust and fiber laden air is sucked.
  • a suction funnel for the space adjacent to the lower scraper and the lower squeeze roller on the side of the cross-belt device.
  • These funnels can be made of any material. Again, the inside of the funnel can also be treated dirt-repellent.
  • suction devices can be coupled to the already existing central suction device of the card.
  • FIG. 1 shows as an example a schematic representation of a card 1.
  • a flake hopper 2 flakes of the card 1 are supplied. The flakes pass in the lower part of the flake filling shaft 2 to beaters 3, 3 'and 3 "of the card 1.
  • the three bursers 3, 3' and 3" open the fiber flakes.
  • the last briseur 3 "passes the roughly parallelized fibers of a carding drum 4.
  • the carding drum 4 cooperates with covers 5 and further parallelizes the fibers, after the fibers have in part passed several revolutions on the carding drum 4, they are taken from a take-off roll 7 removed from the card drum 4, fed to the squeezing roller 8 and finally deposited as a card sliver 9 in a can 10 in a jug.
  • FIG. 2 shows a detailed schematic representation of the acceptance area of a card.
  • the fibers are taken from the take-off roll 7 by a taker 16 removed and passed with the help of a Vliesleitmaschine 13 between two squeezing rollers 8 through, so that a non-woven fabric is formed.
  • This fibrous web is brought together by the transverse conveyor belt 17 and formed into a card sliver or sliver. Unwanted accumulations of dust, protection and short fibers takes place mainly in the space A, which is delimited by the take-off roller 7, the pickup 16 and partially by the two squeezing rollers 8.
  • accumulations occur in the space of the gap between the nip roller 8 and the doctor blade 12, 14 on the one hand and the transverse belt device 17 on the other hand, especially in the region of the transverse belt edges B and C there is an increased risk that accumulate particles.
  • an inventive compressed air device 13 can be used and for the cleaning of the rooms B and C suction devices 11 and 15 are provided.
  • the material throughput and the short fiber and dirt content but also depending on the general conditions in the production plant, such as temperature and relative humidity, you need individual cleaning components or combinations of these.
  • FIG. 3 shows an arrangement with partial suction devices 11 and 15 in the form of a funnel above and below the sliver outlet (view front 'working side, indicated in FIG. 1 with a star). In addition, the flow of the suction air is shown The sliver 19 is transported forward between the two conveyor belts 20, 20 '.
