Definitions

  • the invention relates to a clothing for a cleaning or opening roller, as used in the fiber preparation during the yarn production.
  • Such cleaning or opening rollers are known per se and generally work together with a grate that extends over part of the circumference of the roller.
  • DE-Gbm 81 24 640.4 shows an arrangement in which waste fibers from yarn production, which are located in a vertical shaft, are fed to a cleaning roller by two counter-rotating drawing-off rollers arranged at the lower end of the shaft, which cleaning rollers have a peripheral speed of about 14 m revolves per second.
  • On the circumference of this cleaning roller designed as an impact roller a plurality of strips are arranged, which are equipped with radially extending round pins.
  • the beater roller is closely enclosed by a housing which is partly formed by the grate.
  • the area of the grate takes about a 40% of the circumferential surface, ie extends over an angle of about 140 o.
  • the waste material is repeatedly guided over the grate by means of the beater roller and foreign bodies contained in the fiber material are separated out through the grate by centrifugal force. After several cycles, the fiber material pre-cleaned by means of the beater roller is passed through a feed shaft to a further cleaning machine connected downstream.
  • the object of the present invention is to provide a clothing for a cleaning or opening roller which, on the one hand, produces a sufficient cleaning effect and, on the other hand, a combing effect, but nevertheless does not cause any winding formation.
  • the set which can be fastened to the cleaning or opening roller is a bar provided with teeth, such that, when viewed in a front view, the teeth pointing away from the roller have at least essentially the shape of an isosceles triangle, the thaler between the teeth rising to the rear and the tooth back seen in plan view on the side of the rack facing away from the roller, likewise at least substantially in the form of an isosceles triangle, the tip of which is located on the front of the rack.
  • a cleaning or opening roller 11 consists of a drum 12 which can be driven about an axis of rotation 13.
  • Eight toothed racks 14 are fastened to the surface of the drum 12 in regular sections by means of screws (not shown in FIG. 2).
  • the respective strips 14 extend along respective surface lines of the drum 12, which run parallel to the axis of rotation 13.
  • FIG. 1B The cross-sectional shape of the strips 14 of FIG. 2 is shown on a larger scale in FIG. 1B.
  • the shape of this bar can be seen from FIG. 1B and the front view and top view of FIGS. 3 and 4.
  • the teeth 15 of the toothed rack 14 have tooth tips 16 which are flattened.
  • the front view of each tooth 15 has essentially the shape of an isosceles triangle.
  • the valleys 18 formed between adjacent teeth rise in the rearward direction, which is indicated by the arrow 21 in FIGS. 1, 2 and 4. This means that the front ends 19 of the valleys 18 are located closer to the surface of the drum 12 than the rear ends 23 of the valleys.
  • tooth ridges 24 which are also seen in a top view essentially have the shape of an isosceles triangle, the tip of which is located on the front side 25 of the toothed rack.
  • the toothed strips can be fastened to the drum 12 by means of countersunk screws, the screws extending through corresponding stepped bores 26, so that the heads come to rest in the wider part 27 of the stepped bore 26 and neither catch fibers nor disrupt the air flow around the opening roller.
  • the outer ends of the countersunk heads of the screws lie flush with the surface 28 of the rear strip-shaped region 29 of the toothed strips.
  • the tooth backs 24 fall backwards from the tooth tips 16.
  • this drop angle ⁇ is 15 o with respect to the rearward arrow, which is parallel but opposite to the direction of rotation 31.
  • the rise angle ⁇ of the valleys also in relation to the direction of the arrow, is 36 o .
  • the teeth are arranged at a distance of 14.5 mm from one another and the total height of the bar in the front view according to FIG. 3, ie from the tooth tips 16 to the underside 33 of the tooth bar, is 15 mm.
  • the valleys themselves are semicircular in the lowest area with a radius of 1.5 mm.
  • the deepest point 19 of the valleys is spaced about 3 mm from the bottom 33 of the bar.
  • the flattened tooth tips 16 have a width of 2 mm.
  • Fig. 4 shows a fiber 35 which has folded U-shaped around the tooth 15 '.
  • the tooth back and the air flow achieved by the special shape of the toothed strip keep the two free ends 36 and 37 of the fiber 35 apart, so that no winding can occur. In the course of the operation can the fiber 35 then detach itself from the tooth 15 '.
  • 1A, 1B and 1C differ from one another with regard to the angle of inclination ⁇ of the front sides 17 of the teeth 15.
  • this angle is ⁇ 0 o , ie the front sides 17 of the teeth lie in a radial plane through the axis of rotation 13.
  • this angle is ⁇ + 5 o , ie the teeth are behind inclined at the front.
  • the angle is ⁇ -5 o , ie the teeth are inclined to the rear.
  • FIG. 1A It has been found in practice that an optimal cleaning effect is achieved in the embodiment according to FIG. 1A, the combing effect can be described as good.
  • the embodiment according to FIG. 1B has a better combing action, but a somewhat poorer cleaning action.
  • the embodiment according to FIG. 1C is inferior to the embodiment according to FIGS. 1A and 1B, both with regard to the combing effect and also with regard to the cleaning effect.
