Definitions

  • the present invention relates to a device for cleaning the lid set of a revolving card, according to the preamble of claim I.
  • the suction funnel which extends over the entire width of the cover set, requires a very high suction power for the removal of the cover plaster, so that this arrangement proves to be uneconomical. According to the present invention, this disadvantage should be avoided. This has the features listed in the characterizing part of claim I.
  • Fig. I shows part of a reel II of a card, which is rotatable in the direction of arrow 12 and equipped with a clothing 13.
  • a brush 17 which extends over the entire length of the lid 14, i.e. Extending over the entire width of the cover set and having approximately the same length as the cover 14 can be pivoted about an axis 19 by means of a drive 18.
  • a suction device 20 behind the brush 17. It comprises a suction nozzle 21 and a hose 22 connected to it for discharging the suction air. It also includes a rail 23 along which the nozzle 21 extends in the direction perpendicular to the direction of movement (16) of the cover, i.e. perpendicular to the plane of the drawing, can be moved back and forth and from which it is carried.
  • the reel 12 rotates at a relatively high speed in the direction shown by the arrow 12.
  • the lids 14 of the lid set move relatively slowly in the direction of the arrow 16 (e.g. 10 cm per minute).
  • a carding effect of the textile fibers brought up on the drum set 13 results.
  • Short fibers, foreign bodies, nits and the like are taken away from the clothing 15 of the cover 14. It is therefore filled with such materials in the intake area.
  • the brush 17 In order to clean the sets 15 of the covers 14 before they are used again, the brush 17 is caused to pivot by means of the drive 18.
  • the wires 24 of the brush 17 lift the material to be removed from the set 15 and place it on the tips of the set as a cover plaster.
  • the cover plaster moves with the cover set in the direction of arrow 16. When it reaches the area covered by the nozzle 21, it is sucked away from the nozzle 21. It can thus be seen that in order to completely remove the cover plaster, every point on the surface of the cover set must be vacuumed off at least once.
  • FIGS. 2, 3 and 4 show a view of the surface of the lid set in the direction of arrow 25 of FIG. I, the individual lids 14 not being shown, but only the lateral boundaries or the sides 26 of the lid set being drawn.
  • the direction of the movement of the cover or the set of covers is again indicated by the arrows 16.
  • the speed of the movement of the cover 14 is assumed to be the same size in all of the FIGS. 2, 3 and 4.
  • each of FIGS. 2, 3 and 4 shows the rail 23 in a very schematic manner.
  • the three shown nozzles 27, 28 and 29 carried by the rails 23 have nozzle openings of rectangular cross section and different lengths.
  • the nozzle 27 is the shortest and the nozzle 29 is the longest thereof.
  • the areas defined by the distances cl, c2, the distances dl, d2, the distances el, e2, the distances fl, f2 and the distances gl, g2 are also covered, which finally the nozzles 27, 28, 29 have reached in the positions shown.
  • the lines a, c, e and g were dashed and the lines b, d, f drawn in solid lines. This was only for the purpose of improving clarity.
  • FIG. 2 It can be seen from FIG. 2 that there are triangular surfaces on the surface of the cover set which are not covered by the nozzle 27.
  • the uppermost of these triangles, 33 is delimited by the right side 26 in FIG. 2 and the distances a2 and bl.
  • the second uppermost triangle 34 is delimited by the left side 26 in FIG. 2 and the distances b2 and cl, the third uppermost triangle 35 by the right side 26 and the distances c2, dl etc.
  • the length of the nozzle opening is equal to the length of the cover set advance during a double stroke of the nozzle 28. It can be seen from FIG. 3 that, under these circumstances, triangular surfaces which have not been covered by the nozzle 28 have disappeared. If, as shown in FIG. 4, the nozzle 29 is longer than the length of the cover set advance during a double stroke of the nozzle, uncoated areas are certainly avoided.
  • the nozzle opening is advantageously of rectangular shape.
  • an elliptical shape can also be considered.
  • the longitudinal extension of the nozzle opening is parallel to the direction of movement of the cover 14 shown by arrow 16.
  • An advantageous embodiment of a rectangular nozzle opening consists in that the ratio of the length of the nozzle opening to its width has a value between 3 and 7. In one embodiment, which gave very good results, the rectangular opening was 12 cm long and 2.5 cm wide.
