Definitions

  • the invention relates to a card according to the preamble of claim 1.
  • a card is known from DE-OS 39 28 824, in which the fiber composite is guided essentially along the upper circumference of the reel.
  • a carding element in the form of a revolving cover is assigned in the upper circumference of the drum.
  • dirt particles in the fiber composite e.g. Dust and any parts of the shell that are removed by the knives on the circumference of the reel.
  • the fibers straighten up due to the relatively high peripheral speed of the reel, and the dirt particles in them are pushed outwards by centrifugal force. The dirt particles are then excreted by the separation knives, while the fiber composite continues under the respective separation knife.
  • the invention is based on the technical problem of redesigning the card of the type described at the outset in such a way that, with a simple construction, the card is safe ⁇ > the dirt particles are guaranteed without impairing the carding process.
  • This problem is solved in the generic card according to the invention by the characterizing features of claim 1.
  • the dirt separating elements can be a combination of separating knives and carding elements.
  • the dirt particles are then discharged from the dirt collecting space by a suction device which is uniform for all dirt separating elements and which is preferably arranged at the greatest possible distance from the separation points. Due to the remote arrangement of the suction device, the fibers are no longer sucked in or a cross flow occurs.
  • a card with a tandem arrangement of reels is known from EP-AS 0 314 310, in which at least the fiber composite in the lower reel is guided along the lower circumference, but this arrangement results solely from the fact that an extended processing path for the fiber composite is achieved shall be. With this card, most of the dirt particles are removed from the upper reel, which in turn results in strong suction devices that are brought close to them.
  • part of the processing path for the fiber composite is already realized on the licker-in roller.
  • the arrangement of the carding elements on the licker-in roller offers the possibility of changing the reel diameter depending on the additional machining path gained on the licker-in roller.
  • the licker-in roller is arranged according to claim 3.
  • the processing path for the fiber composite is extended by the carding elements arranged on the circumference of the opening roller.
  • the drum diameter can be reduced depending on the machining path obtained on the opening roller.
  • the fiber flakes for the production of the fiber composite are mostly fed through transport shafts that are attached to the ceiling of the production hall.
  • the embodiment according to claim 6 is advantageous.
  • the overall height of the card which is essentially predetermined by the removal device, is not unnecessarily increased.
  • the embodiment according to claim 8 has the advantage that below the drum there is enough collecting space for the dirt particles, which results in the greatest possible achievable dirt collecting space with little effort.
  • the suction device can be arranged particularly far from the discharge points, as a result of which the suction flow is further evened out and cross flows are avoided.
  • particularly long machining paths are achieved on the lickerin roller and the opening roller. This assembly and the entire card are very compact due to the clever arrangement of the carding elements.
  • dirt separating elements are arranged on the lickerin roller according to claim 12. This removes larger dirt particles in advance.
  • the dirt particles deposited on the licker-in roller and possibly thrown away by the relatively high peripheral speeds of the licker-in and opener rollers are removed in a particularly advantageous manner in the card design according to claim 13, since all dirt particles occurring in the processing area of the fiber composite are captured by the suction device connected to the large-volume dirt-collecting space.
  • the fiber composite is cleaned in front of a carding element by the Ausseheidemesser.
  • the heavier dirt particles are pushed outwards by the relatively high speed of the reel and are knocked off by the knives. This arrangement also allows the Ausseheidemesser to be attached to the subsequent carding element.
  • a card designed according to claim 24 ensures a correspondingly large design of the dirt collecting space arranged under the drum.
  • Fig. 1 shows a card according to the invention in a schematic representation
  • Fig. 2 shows the roller assembly of FIG. 1 in an enlarged view.
  • the card shown schematically in Fig. 1 has a housing 1, from which the remaining card elements are largely supported.
  • a large-volume dirt collecting space 2 is formed in the housing 1 and is connected to a suction device 4 via a suction shaft 3.
  • a drum 5, a lickerin roller 6, an opening roller 7 and a take-off roller 8 are arranged in the upper half of the housing 1.
  • the lickerin roller 6, the opening roller 7 and the drum 5 are driven by a common motor 9.
  • These three rollers 5, 7, 8 are each provided with a drive wheel 10.
  • a traction device 11 can be set in motion by a drive wheel 12 on the motor 9.
  • the traction means 11 is placed over the drive wheel 12, the drive wheels 10 and deflection rollers 13.
  • a feed device 14 is assigned to the lickerin roller 6.
  • the feed device 14 comprises one or more feed rollers 15.
  • a filling shaft is operated via a flake feed 17, which is supplied with fiber flakes from a transport shaft.
  • the take-off roller 8 is assigned a dispensing device 19 which is arranged above a can 20.
  • the jug stick 20 is located above a fleece jug 21.
  • carding elements 22a are arranged essentially on the lower circumference of the drum 5, each of which is preceded by a separating knife 23.
  • the lickerin roller 6 is essentially provided with carding elements 22b and 22c on its lower circumference and the opening roller 7 substantially on its upper circumference.
  • the lickerin roller 6, the opening roller 7, the drum 5 and the take-off roller 8 are each provided on their outer surface with a clothing (not shown).
  • the sets of rollers 5, 6, 7 are correspondingly with the carding elements 22a, 22b, 22c in Intervention can be brought.
  • the directions of rotation for the rollers 5, 6, 7, 8 are given with the capital letters A, B, C, D and the alignment of the sawtooth-like clothing with the capital letters E, F, G, H. It turns out that the lickerin roller 6, the opening roller 7 and the drum 5 have a sawtooth-like clothing on the circumference, the directions of action E, F and G of which correspond to the corresponding direction of rotation A, B or C, and that the take-off roller 8 has a circumference has sawtooth-like clothing, the direction of action H opposite to the direction of rotation D.
  • the feed device 14 and the take-off device 19 have approximately the same level.
  • the lowest of the delivery rollers 15 is arranged at an angle a to the horizontal on the upper circumference of the lickerin roller 6.
  • the lickerin roller 6 and the opening roller 7 are arranged at the same height and have the same diameter.
  • the opening roller 7 is assigned to the upper circumference of the reel 5 at an angle b with respect to the horizontal.
  • the drum 5 and the take-off roller 8 also have the same diameter.
  • the take-off roller 8 is arranged on the upper circumference of the reel 5 at an angle c with respect to the horizontal.
  • the take-off device 19 engages with the upper circumference of the take-off roller 8 at an angle d with respect to the horizontal.
  • the opening roller 7, which is in functional engagement with the lickerin roller 6, has a direction of rotation B which is opposite to that of the lickerin roller and a higher speed.
  • the sets of the two rollers 6, 7 have the same direction of action F and G at their contact point. Due to the higher speed of the opening roller 7, the pre-opened fiber composite is entrained by it and guided past the carding elements 22c assigned to it. This opens and aligns the fiber composite.
  • the opening roller 7 and the drum 5 have opposite directions of rotation H and C and at the transfer point the same directions of action E and G of their sets.
  • the peripheral speed of the drum 5 is higher than that of the opening roller 7, whereby the fibers of the drum 5 overlap will be
  • the fibers stand up in front of the discharge knife 23 and the heavier dirt particles are pushed outwards.
  • the erected fibers are guided past the separation knives 23.
  • the flexible fibers bend away under the separation knives 23, while the dirt particles are removed from the fiber composite.
  • the carding elements 22a which are assigned to the drum 5, take over the main part of carding the fibers.
  • the take-off roller 8 has a direction of rotation D opposite to the drum 5. At the transfer area of the two rollers 5, 8, the directions of action E and H of their sets are opposite. In addition, the peripheral speed of the take-off roller 8 is significantly lower than that of the reel 5.
  • the removal device 19 detaches the fiber composite from the take-off roller 8, forms a sliver and passes it directly into the can 20 of the spinning can 21.
  • the dirt particles mainly deposited on the reel 5 and any remaining fibers are removed downwards. They fall into the dirt collecting space 2 located under the rollers 5, 6, 7, 8 and are removed there by the suction device 4. Due to the relatively large distance between the suction device 4 and the separating knives 23, a relatively low-vortex air flow is ensured in the large dirt collecting space 2. The air flow is calmed so far that no fibers are sucked out of the fiber composite and no cross-currents arise which lead to non-uniformities in the fiber composite. It is favorable for the production process of the fiber composite that almost no dirt particles or fiber residues can be deposited above the drum 5.
  • the arrangement of the individual rollers 5, 6, 7, 8 relative to one another provides a relatively short embodiment of a card.

Abstract

Une machine à carder utile pour fabriquer un ruban de carde ou un non-tissé fibreux se caractérise par un guidage des fibres situé le long du côté inférieur du tambour (5) et par une chambre (2) de collecte de déchets située sous le tambour et pourvue d'un dispositif aspirateur (4). Le tambour est équipé d'éléments de cardage (22b) et de lames de séparation (23) situés sensiblement sur sa circonférence inférieure. Le tambour ouvreur (7) et le tambour briseur (6) sont associés à la circonférence supérieure du tambour (5) et sont eux aussi pourvus d'éléments de cardage (22c, 22b). Le dispositif (14) d'alimentation du tambour briseur et le dispositif (19) d'amenée au peigneur (8) sont situés à peu près au même niveau. Grâce au guidage des fibres autour de la face inférieure du tambour, les particules de saletés peuvent être très facilement éliminées et notamment évacuées. La chambre volumineuse (2) de collecte de déchets permet d'appliquer un courant d'aspiration uniforme sur tous les éléments d'élimination des saletés sans affecter la qualité du non-tissé fibreux. En outre, le tambour ouvreurs (7) et le tambour peigneur (8) peuvent être situés sur la circonférence supérieure du tambour. On obtient ainsi une machine étroite et donc très compacte.
