Definitions

  • the invention relates to a casing of a card according to the preamble of patent claim 1.
  • the cards of the current design are surrounded by a sheathing which is required on the one hand for safety-related regulations and on the other hand for conditions of air pollution control.
  • suction devices are provided within the casing, which generate a certain negative pressure in the card's encased space. This removes the fiber parts, shell parts and other dirt parts.
  • the cards known today such as the C4 / 1 from RIETER or the DK 740 from Trützschler, one or more suction openings with a small suction area in relation to the area of the sheathing, partially with a grid, are provided in the sheathing provided with a filter cloth, are covered.
  • the smaller cracks and openings in the casing must be sealed so that no false air is sucked in. Due to the high flow velocities of the sucked air in the area of these openings and cracks, flight and dirt are sucked in from the spinning room. To prevent this, it is necessary that the casing is sealed as well as possible so that fresh air is only sucked in at the openings provided. To ensure that the suction effect does not drop too much, the filter cloth or filter must also be cleaned regularly from the fiber mat that forms.
  • the object of the invention is now to improve the suction of the fiber fly accumulating in the jacket of a card, the shell and dirt parts and the like in such a way that the requirements for the sealing and for the regular cleaning of the filter cloth can be substantially reduced.
  • the invention has the essential advantage that the air flows within the card are significantly lower, so that the sealing of the casing is no longer important. With the suction power of the suction device remaining the same, the amount of air sucked in increases, which leads to improved dust removal. Since the intake air flows into the casing at a much lower speed, the floating parts such as flying fibers etc. are only sucked in to a very small extent and therefore with a significantly lower volume flow density, so that in many cases the filter cloth in front of the intake openings can be omitted, for example then when the spinning room is clean enough.
  • the casing 1 of a card is drawn only very schematically in side view, without observing the correct scales.
  • the feed table 2 can be seen on the right-hand side and the card sliver outlet 3 on the left-hand side.
  • the drawn side of the casing 1 consists of two doors 4 and 5, which covers the card indicated by dashed lines with reel 6, feed roller 7 and beater 8.
  • rectangular suction openings 9 and 10 are provided, which are provided with bars 11.
  • FIG. 2 the same reference numerals are used for the same elements as in Figure 1.
  • the drum 6 is indicated with its axis of rotation shown in dashed lines.
  • the intake air represented by arrows 12 is drawn in through the intake openings into the intake pipes 13 of an L-shaped channel 14 known from EP-A-0 340 458.
  • the spatial arrangement of the suction device 15 can also be effective centrally (not shown here) and thus simultaneously for several cards. However, this is not important for the present invention.
  • the suction openings 9 and 10 (FIG.
  • FIG 3 shows the suction opening 4 or 5 with the border 16 and the bars 11, of which only two are shown here. In reality there are a lot of them available.
  • the bars 11 have a U-shaped profile and are directed with the legs of the U inwards.
  • the U-profile is chamfered or rounded at the edges 17 in order to prevent fibers from getting caught and thus the suction openings being covered over time. This creates a kind of self-cleaning effect.
  • the border 16 is also flanged inwards and, for the reason mentioned, also has a beveled or rounded edge 18.
  • the distance a between the outer sides of the legs of the U-shaped lattice bar 11 is between 10 and 40 mm, preferably about 20 mm.
  • the distance b between two bars 11, again measured between the outside of the legs, is at most 40 mm and is preferably about 20 mm.
  • the lattice bars 11 are designed as a coherent lattice, which is mounted from the inside of the casing into the suction openings 9 and 10. This prevents the bars 11 from being removed from the outside without opening the otherwise locked doors 4 and 5.
  • the effective suction area of the suction openings 9 and 10 is the area formed by the suction openings 9 and 10 minus the area covered by the bars 11.
  • the effective suction area of the suction openings 9 and 10 must be at least 0.4 m2, preferably at least 0.5 m2.
