Definitions

  • the present invention refers to a treatment device linkable to a picker or carding machine roller to modify a fibre layer, especially cotton, on a circumferential surface of the roller.
  • the cotton staples still mixed with dust, impurities and the remaining husk are fed, for example through a pair of feeder rolls, into a beater roller (or simply beater), whose circumferential surface is equipped with grippers or a saw-toothed lining to grasp the cotton fibres and pull them away.
  • a beater roller or simply beater
  • the fibre layer and above all its heavier components, such as the impurities and husk remnants, are moved radially outwards.
  • This radial fibre and impurity movement is partially hindered by the grippers and saw teeth of the circumferential surface of the beater roller and/or the angled projections within the beater roller, against which the fibre layer is beaten.
  • One or more treatment devices are linked to the beater roller to open, dust and card or comb the cotton fibres before they are separated by the beater roller, for example using a suction device which channels the fibres thus treated into the following spinning line station or into an attached silo.
  • Patent DE 39 02 204 describes the use of a fixed carding segment followed by a regulating vane which guides the fibre layer, modifying its thickness (radially with respect to the beater roller rotation axis), a separation cutter placed after the regulating vane to cut (that is, separate in a fluid dynamic sense) the outermost part of the fibre layer containing the heavy impurities, which are removed by a suction mouth placed in line with the separation cutter.
  • the protruding free end of the fibre rubs against the separation cutter and tends to slide between the cutter and the roller, thus being compacted, while the husk, which offers greater resistance, is sucked away.
  • the aim of this invention is thus to make available a fibre treatment device having features able to overcome the described problems of the known technique.
  • a treatment device linkable to a picker or carding machine roller to modify a fibre layer on a circumferential surface of this roller, such device comprising at least one regulating vane to guide the fibre layer against this circumferential surface in order to limit its thickness.
  • the device is characterised by the facts it includes a compaction organ positionable before the regulating vane seen from the roller rotation direction, in which said compaction organ compacts the fibre layer and guides it towards the circumferential roller surface before the regulating vane.
  • figure 1 is a sectional view of a picker equipped with a treatment device according to this invention
  • FIGS. 2 and 3 are sectional views of a treatment device according to this invention.
  • figure 4 is a magnified sectional view of a detail of figure 2;
  • figure 5 is a magnified sectional view of a detail of figure 3;
  • figure 6 is a diagram showing the functioning of a treatment device using known technology
  • figure 7 is a diagram showing the functioning of a treatment device according to this invention.
  • Figure 1 shows a picker 1 with three beater rollers 2, 3, 4 placed alongside and counter-rotatable with speeds v2, v3 v4 increasing from the first roller 2 to the last roller 4, in order to carry a fibre layer 5 and transfer it from one roller to the next.
  • a pair of feeder rolls 6, 7 are used, whose circumferential surfaces 8 are preferably shaped; in particular the upper feeder roller 6 has the form of a cog wheel and lower feeder roller 7 has a circumferential surface 8 in the form of saw teeth.
  • the circumferential surfaces 9 of beater rollers 2, 3, 4 are also equipped with a so-called "trimming" 10, that is a saw-toothed lining or grippers radially protruding from the circumferential surface 9 with a rounded or pointed free end.
  • One or more treatment devices 11, 12 are linked to the beater rollers 2, 3, 4 to open, dust and card or comb the fibres, for example cotton, before they are separated by the final beater roller 4, for example using a suction device 13 which channels the fibres 5 into the subsequent device on the spinning line or into an attached silo (not shown in the figures).
  • first separation cutter 14 After the pair of feeder rolls 6, 7 (seen in the direction of rotation of the first beater roller 2) there is a first separation cutter 14 to cut, or, in other words, separate in a fluid dynamic sense the outermost part of the fibre layer 5 containing heavy impurities. In line with this first separation cutter 14 is a first suction mouth 15 to remove the impurities separated from the fibre layer 5.
  • first separation cutter 14 After the first separation cutter 14 is a first fixed carding segment 16 followed by a first regulating vane 17 which guides the fibre layer 5, modifying its radial thickness with respect to the rotation axis R2 of the beater roller 2.
  • the first cutter 14, the first suction mouth 15, the first fixed carding segment 16 and the first regulating vane 17 are all mounted on a common support element 18.
  • the second beater roller 3 rotates with a greater speed than and in the opposite direction to beater roller 2 and is side by side with it, so as to allow the transfer of the fibres 5 from the first beater roller 2 to the second beater roller 3.
  • the second fixed carding segment 16b and the second regulating vane 17b are mounted on a third common support element 18b.
  • the following and final beater roller 4 is rotatable with speed v4 greater than and in the opposite direction to the previous beater roller 3, and is placed alongside this in order to allow transfer of fibre 5 from the previous beater roller 3 to the final beater roller 4.
  • a treatment device 12 which includes at least one third regulating vane 17d to guide the fibre layer 5 against the circumferential surface 9 of beater roller 4, to modify or in fact limit the thickness of fibre layer 5, as well as a compaction organ 19 positioned before the third regulating vane 17d seen in the rotation direction of beater roller 4 in which the compaction organ 19 compacts the fibre layer and guides it towards the circumferential surface 9 of the beater roller 4 before the third regulating vane 17d.
  • the compaction organ 19 and the third regulating vane 17d are both placed on a fifth support element 18d and the fourth separation cutter 14e and the fourth suction mouth 15e are placed on a sixth support element 18e.
  • At least one part of the circumference of the beater roller or rolls 2, 3, 4 has one or more angled projections 20, for example one or more projections in aluminium or blades in steel shaped in such a way as to impede the loss of fibres flung radially outwards by the centrifugal force generated by the beater roller rotation.
  • suction device 13 or another means to remove the treated (opened, dusted, cleaned, carded etc) fibres is placed in relation to the last beater roller 4 in order to allow the removal of the fibres on the circumferential surface 9.
  • the suction device 13 has a rectangular duct 21 oriented tangentially to the (last) beater roller 4 in order to produce a suction force tangential to the beater roller circumferential surface 9.
  • the compaction organ delimits, together with beater roller 4 circumferential surface 9, a passage 22 for the fibre layer 5 which is narrowed in the direction of rotation of the beater roller 4 so that the fibre layer 5 is pushed from the compaction organ 19 towards the circumferential surface 9, and specifically within the roller lining of beater 4, and is consequently compacted.
  • the regulating vane 17d is shaped and positioned such that it limits the displacement or radial re-swelling of the fibre layer 5 previously compacted by the compaction organ 19.
  • the compaction organ 19 and the regulating vane 17d are preferably configured in such a way that the fibre passage 22 between the beater roller 4 and the compaction organ 19 is radially narrower than the fibre passage 23 between the beater roller 4 and the regulating vane 17d.
  • the compaction organ 19 ideally includes a movable and preferably adjustable shaped piece 26 fixed to a support element 18d.
  • the compaction organ 19 has a substantially smooth compaction surface 24, turned towards the circumferential surface 9 of the beater roller 4 and shaped in order to form the above mentioned passage 22 which narrows in the direction of rotation of beater roller 4.
  • the compaction surface 24 is generally flat and oriented in order to approach the circumferential surface 9 of the beater roller 4 in its direction of rotation.
  • the compaction surface 24 is curved towards the circumferential surface 9 of the beater roller 4 in the direction of its rotation.
  • the compaction surface 24 or more generally the compaction organ 19 has at least one discontinuity, preferably a step 25 which provokes a sudden narrowing of passage 22.
  • a dead zone is advantageously formed, that is a dead or stagnant angle in a fluid dynamic sense, which increases fibre compaction towards the circumferential surface 9, that is in the lining of the beater roller 4.
  • the position of regulating vanes 17-17d and of separation cutters 14-14e are adjustable so as to allow regulation of the (radial) thickness of both the fibre layer 5 and its outer part which is separated by the separation cutter 14-14e.
  • the position of the support element 18d holding the compaction organ 19 and the regulating vane 17d is adjustable in order to vary its distance from roller 4.
  • the distance between beater roller 4 and the sixth support element 18e holding the separation cutter 14e and the suction device 15e is also adjustable.
  • Figure 7 is a diagram showing the functioning of a treatment device according to this invention.
  • the fibre layer fed into it wraps around the roller's circumferential surface and swells radially due to centrifugal force, allowing the heaviest impurities and pieces of husk to separate from the fibres and move radially outwards.
  • centrifugal force displaces even the light fibres outwards, forming a fibre layer separated radially from the beater roller (but still held by the roller's grippers or lining) and, sometimes, compact and thin.
  • the compaction organ 19 re-beats this fibre layer and pushes it towards the beater roller's circumferential surface, forming, in front of the regulating vane, a generally compact fibre layer, in close contact with the beater roller circumferential surface and penetrating sufficiently within the lining.
  • the fibre layer Before passing through passage 23 delimited by the regulating vane 17d, the fibre layer re-swells radially due to centrifugal force, allowing heavy impurities to travel further outwards and to separate definitively from the fibre.
  • the regulating vane guides the fibre-impurity layer or film thus obtained and adjusts its thickness to allow correct impurity separation (radially outer part) through the separation cutter.
  • the invention's treatment device more complete separation of the impurities from the fibres is obtained as well as a fibre layer more compacted towards the lining and thicker radially, with a clearer separation of the impurities.
  • the picker may include only one, or two or more beater rollers, depending on the fibre treatment needs.
  • the treatment device including the compaction organ may be linked to one only, or more than one, or all the picker's beater rollers and the means feeding the cotton staples or fibres to the beater rollers may include one or more channelling belts or only one feed roller.
