Definitions

  • the invention relates to a device for separating dirt from a nonwoven fabric located on a rotating toothed roller, namely by means of a stationary separating surface which is opposed to the rotational movement of the toothed roller but is adjustable in the radial direction of the toothed roller, and a separating surface, seen in the direction of rotation of the toothed roller upstream and also stationary preparation element, which is also adjustable in the radial direction of the toothed roller, a separation gap remaining free between the preparation element and the separation surface.
  • the aforementioned devices are known, for example from GB-PS 1 058 894, in which the fleece lying on the drum after passing through the revolving cover by means of a knife counter to the direction of rotation of the drum, dirt is removed from the surface of the fleece and is suctioned off by means of a suction channel.
  • a guide surface In front of the knife, seen in the direction of rotation of the spool, is a guide surface that guides the fleece.
  • the guide surface is part of a catch rail which, like the guide knife, is adjustable from and against the drum surface.
  • the latter elements can be adjusted such that the distance between the cutting gap and the knife edge and the collecting rail can be changed.
  • the card not only requires higher throughput, but also an improved card sliver, so that development work had to be carried out in the system of the individual card functions in order to obtain a more uniform card sliver with higher output, which also has less nits, dirt content and less fiber damage.
  • the object of the invention is therefore that the prior art mentioned at the beginning is accompanied by the characteristic that the preparatory element is one of the Has toothed roller circumference opposite structured surface.
  • FIG. 1 schematically shows the cross section of a card 1 with a reel 2, a traveling cover 3 arranged above it, a breeze 4 and a doffer roller 5.
  • the elements in front of the breeze and after the doffer roller are not shown for the sake of simplicity.
  • a preparation element 6, a suction device 7 and a separating knife 8 are provided one after the other, viewed in the direction of rotation D of the drum. This combination corresponds to the combination shown in FIG. 2.
  • a combination according to FIG. 3 is provided, namely, in that order, a preparation element 6, a suction device 7 and a separating knife 9 the separating knife is adjustably arranged on a carding element 10 in the arrow directions 11.
  • a carding element 12 is arranged in the pre-carding zone in front of the preparatory element 6 and after the carding element 10, while carding elements 12 are provided after the separating knife 8 in the postcarding zone and in the subcarding zone, namely in the postcarding zone one and in the subcarding zone five.
  • the carding elements 12 are the same carding elements as the carding element 10, but without the separating knife 9.
  • the elements 8 and 10 are arranged to be adjustable in the arrow directions 14, which is also shown and described with the aid of FIGS. 17 and 18.
  • FIGS. 2 and 3 also schematically show an all-steel fitting 15 belonging to the drum 2, which has been pulled up on the surface thereof.
  • the preparation element 6 is composed of a support body 16 and an all-steel fitting 17 arranged thereon.
  • the way in which such all-steel fittings are attached to such support bodies 16 is very well known from the prior art; for example from CH patent 543 607 and therefore not described further.
  • the inventive aspect of the all-steel clothing 17 of the preparatory element 6 is that the teeth of this all-steel clothing are directed essentially in the direction of movement D of the reel and that the breast angle ⁇ (see FIG. 2a) is in the range from 0 to 75 degrees.
  • the term breast angle is defined in DIN standard sheet No. 64 123 / sheet 1.
  • the separating knife 8 has a similar shape to the supporting body 16 of the preparation element 6, but has a cutting edge 18 directed against the direction of movement D of the drum 2 and a smooth foot surface 22.
  • a separating gap 19 remains open between the cutting edge 18 and the all-steel clothing 17.
  • the dirt separated by this separating gap 19 is taken up by the suction 7 and conveyed into a filter (not shown).
  • This suction 7 consists of a U-shaped channel 20 described later, the foam rubber seals 21 on the preparation element 6, respectively. abuts the separating knife 8 without actually exerting any force on it.
  • the foam rubber can be glued to the channel 20.
  • FIG. 3 partly has the same elements as FIG. 2, which is why the same elements are provided with the same reference symbols and are not described again.
  • FIG. 3 has an embodiment that is advantageous compared to FIG. 2, in that a separating knife 9, which is relatively smaller than this, is provided on the carding element 10 instead of the separating knife 8.
  • a carding set 23 also called all-steel set
  • This all-steel set 23 has a normal carding set, ie not a type of tooth like the all-steel set 17. The functions of the carding sets are known per se and are therefore not described further.
  • the manner in which the separating knife 9 is fastened to the carding element 10 is not shown further, but it can either be fixedly connected to the carding element 10 or displaced in the directions of movement 11 by means of a guide slot and screws guided therein, which are anchored in the carding element 10 ascertainable.
  • the preparation element 6 and the carding element 10 each have to be moved separately in the directions of movement 13, respectively. 14, be adjustable, which is not prevented by the foam rubber seal 21 of the suction 7, since the adjustment is kept in a very small frame.
  • FIGS. 4, 5 and 8 each show a preparation element, which shows an alternative to this instead of the all-steel fittings 17.
  • FIG. 4 has fish scales 24 instead of the all-steel set 17
  • FIG. 5 has longitudinal grooves 25
  • FIG. 8 has longitudinal shafts 26.
  • the technical and technological function of the all-steel set 17, respectively. the fish scales 24, the grooves 25 and shafts 26, as well as the further variants described in the following, is to set the fiber fleece lying on the all-steel clothing 15 of the reel 2 in vibration due to the unevenness in order to use the centrifugal force, which also acts on the dirt parts in the fleece, to cause the To convey dirt particles better to the surface in order to separate them at the knife edge 18 and to convey them away by means of the suction 17.
  • FIGS. 6 and 7 show a corrugated surface (instead of the all-steel fitting 17) (also referred to as “corded”), while FIGS. 9 and 10 with crater-shaped depressions 28 and FIG. 13 with wart-shaped ones Elevations 29 are provided.
  • FIGS. 11 and 12 show a further step in realizing the inventive concept by providing the preparation element 6.1 with a cavity 30 which on the one hand has a connection opening 31 and a perforated plate 32.
  • the hole diameter and the number of holes 33 of the perforated plate 32 are to be determined by experiments and are not further explained here.
  • a hole diameter between 0.3 and 1.5 mm applies as a guideline.
  • FIG. 14 shows a variant of the device from FIG. 3, in that a knife 34 on the carding element 10 moves or moves in the directions of movement 35. is arranged lockable.
  • the moving resp. the knife 34 is fixed with the aid of an adjusting screw 37 which can be rotated in a support 36 but is fixed against axial displacement and which is connected to the knife 34 by means of its thread.
  • the support 36 is firmly connected to the carding element 10 by means of screws 38.
  • the suction 7.1, respectively. the channel 20.1 has the same function as the suction 7, respectively. the channel 20.
  • the latter is sealed off from the atmosphere in the area of the knife 34 by means of a lip seal 75 which bears against the knife 34 and is glued to the channel 20, 20.1.
  • FIGS. 15 and 16 show an application of the preparation element 6.1 from FIGS. 11 and 12 with a plurality of connection openings 31, all of which are connected to an air manifold 39 via connection stubs 40.
  • the air manifold in turn is connected to either a positive pressure air source 41 or a negative pressure air source 42.
  • a rotatable end flap 43 is provided in the air manifold 39, which is connected to the drive shaft of a drive motor 44.
  • this rotatable end flap 43 The function of this rotatable end flap 43 is to provide a pulsating bottom in the air manifold. or to generate overpressure air flow. It is therefore only used when this pulsating air is used.
  • the end flap 43 can remain in the open position when the pulsating air is not being used.
  • the function of the pulsating air consists in the aforementioned vibration of the fleece lying on the drum set 15 before the knife edge 18, or. the knife edge of knife 9 or 34 reached.
  • air manifold is in itself not very suitable for overpressure operation, since in such a case it is more of an air distribution line. For the sake of simplicity, the same term is used for both types of procedure.
  • FIG. 17 corresponds essentially to FIG. 1 of the as yet unpublished German patent application DE-38 11 679.0 and is mentioned again here in order to show the anchoring of the elements 6, 8, 10 and 12 with regard to mobility in the radial directions of movement 13.
  • FIG. 18 does not correspond to the aforementioned German patent application, but is an additional variant for this application in order to make the elements 8 and 10 displaceable even in the circumferentially directed movements 14.
  • FIG. 17 now shows some details of the card 1 to explain the adjustable fastening of the elements 6, 10 and 12.
