Definitions

  • the present invention relates to a method and an apparatus for Removal of dust, waste and short fibers in the exit zone of a card or Card, which is a take-off roller or doffer, a take-off and an upper a lower nip roller, and has a transverse conveyor belt.
  • a non-woven fabric is formed which is brought together by the transverse conveyor belt to form a sliver.
  • the fibers are passed several times from roller to roller, and through appropriate arrangements of the rollers there are spaces in which the dirt can accumulate with preference.
  • the squeeze rollers in particular create circular air movements in these rooms, which also have a negative effect on the removal of this contamination.
  • this accumulation of particles is most often a problem.
  • the degree of pollution in these rooms depends on that too processing material, the production quantity, the degree of pollution of the Raw material and the cleaning efficiency of the upstream cleaning processes as well as general conditions such as temperature and relative humidity in the production plant.
  • the compressed air device is advantageously in the area between the take-off roller, of the customer and the squeeze roller arranged so that the air flow of the Blows through the opening gap between the lower squeeze roller and take-off roller.
  • the Air flow should be guided in such a way that it does not follow the normal course of fleece removal disturbing or impaired.
  • the duration of the generated air flow is adjustable.
  • the compressed air device can then optionally generate a continuous flow of air or work at intervals, for example in Intervals of 1 to 60 minutes, advantageously 3 to 30 minutes, an air blast for generate a duration of up to 60 seconds, advantageously up to 10 seconds.
  • the interval sequence and / or intensity from the controller is set and / or controlled, for example with an adjustable and / or controllable solenoid valve.
  • the compressed air device is advantageously in one Fleece guide plate or a fleece guide bridge integrated, if these are available. This However, integration should take place without the function of the fleece baffle or the To influence or impair the fleece guide bridge.
  • the compressed air device can be made of any suitable material, advantageously from a hollow profile made of chrome steel sheet or aluminum, possibly anodized.
  • the profile in suitable area optionally with at least one slot or hole become.
  • Combinations of slit-shaped, oval or round openings are conceivable.
  • the choice of shape and number of holes depends on the working width of the entire compressed air profile and the number of feed positions for the Compressed air feed in the profile.
  • An example of a solution according to the invention is one Arranged in a line of several round holes with a feed at the head or foot of the compressed air device.
  • the holes can also be in a pattern or staggered.
  • a waste baffle is attached below the gap where the dirt is blown out, which transports the dirt particles outside the cardboard formwork, where they are disposed of during normal floor cleaning.
  • the construction of the waste baffle can also be made from any suitable material, advantageously from chrome steel sheet 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.
  • An alternative solution would be to place a suction device below the gap. This suction device can advantageously be coupled to the existing central suction device of the card. The dirt is then fed into a filter system.
  • the solution according to the invention of removing the accumulated material is rather the arrangement of one or more suction devices.
  • a play a decisive role how much undesirable material accumulates and whether one only in the area of the sliver outlet, where the most particles are accumulate, or a suction device over the entire working width of the card needed. This can also be a decisive factor whether you have one at the top and / or at the bottom Suction device is needed.
  • the sliver outlet can be in the middle or at the Side be arranged; the partial suction device therefore also in the middle or on the side.
  • the suction device according to the invention for the space above the upper one Scraper knife and the cross belt device is formed by a suction funnel, whereby the dust and fiber-laden air is extracted.
  • a similar arrangement is intended for the room next to the lower scraper and the lower Pinch roller on the side of the cross belt device.
  • These funnels can be made any material. Again, the inside of the funnel additionally treated dirt-repellent.
  • suction devices can also advantageously be connected to the existing ones central suction device of the card.
  • FIG. 1 shows a schematic representation of a card 1 as an example Flake filling chute 2 is fed to flakes of card 1.
  • the flakes arrive in the lower area of the flake filling shaft 2 to beaters 3, 3 'and 3 "of the card 1.
  • the three breezeers 3, 3 'and 3 open the fiber flakes.
  • the last breeze 3" transfers the roughly parallelized fibers of a card drum 4.
  • the card drum 4 works with Cover 5 together and parallelize the fibers even further.
  • FIG 2 shows a detailed schematic representation of the take-off area Teasel.
  • the fibers are removed from the take-off roller 7 by a pick-up 16 removed and with the help of a fleece guide bridge 13 between two squeeze rollers 8 passed through, so that a non-woven fabric is formed.
  • This nonwoven is made by the transversely extending conveyor belt 17 merged and into a carding belt or Sliver shaped. Unwanted accumulations of dust, protection and short fibers takes place especially in room A, which is by the take-off roller 7, the customer 16 and is partially delimited by the two squeeze rollers 8.
  • a compressed air device 13 according to the invention can be used to clean room A. are used and for the cleaning of rooms B and C are according to the invention Suction devices 11 and 15 are provided. Depending on the size of the Working speed, 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, one needs individual according to the invention Cleaning components or combinations of these.
  • the upper and lower suction devices can be arranged over the entire working width of the card or only over a part.
  • the area around the sliver outlet is most at risk because fibers and dirt carried along can come together with the newly formed sliver.
  • 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 on the front 'working side, indicated with a star in FIG. 1).
  • the flow of the suction air is shown.
  • the sliver 19 is transported forward between the two conveyor belts 20, 20 '.
