Definitions

  • the following invention relates to a device for the preparation of flock fibres to be supplied to a carder, i.e. a batt-forming machine.
  • batt-forming line refers to a set of machines for the treatment of fibres, disposed up-line from the carding machine, which treat the fibre accumulated in bales to supply it, in flock and opportune conditions, to the carding machine.
  • Batt-forming lines are currently known primarily comprising a machine with a pick-up trolley, for picking up fibre from the bales, a porcupine, for opening and cleaning the fibres, a mixer, for mixing the fibre, and auxiliary devices for moving the fibre and feeding the carding machine.
  • the abovementioned machines are disposed according to a preset sequence that assures the obtaining of optimum conditions of the flock fibre supplied to the carding machine.
  • the transfer of the fibre from one machine to the next takes places in feeding pipes, generally, in air pressurised or depressurised currents generated by fans.
  • the opening action performed by the openers is partially frustrated by a partial compacting that the fibre undergoes as it accumulates in the mixer and opener silos. It is known that this negatively influences the efficacy of both fibre mixing and cleaning.
  • the aim of the present invention is to make a batt-forming machine able to satisfy the aforesaid requirements and overcome the drawbacks mention relating to the current art.
  • FIG. 1 illustrates a batt-forming line comprising a batt-forming machine according to the present invention, in a preferred embodiment
  • figure 2 illustrates the batt-forming machine of figure 1 ;
  • figure 3 represents an enlargement of detail III of figure 2 ;
  • FIG. 3a illustrates a side view of a batt-forming machine opening wheel
  • figure 4 represents an enlargement of detail IV of figure 2 ;
  • batt-forming line indicates a set of machines disposed up-line from a carding machine to supply it with flock fibres having opportune conditions for carding.
  • the batt-forming line comprises a plurality of batt-forming machines 10, at least one inlet pipe 12 for supplying the fibre to be processed to the machine 10 and at least one outlet pipe 14 for the supplying of the processed fibre to a subsequent batt-forming machine 10' or to a subsequent machine for other processing.
  • the batt-forming machine 1 comprises at least one silo 16 for accumulating the fibre to be processed, operatively connected to the inlet pipe 12.
  • the silo 16 has a chamber 18 for accumulating the fibre, open for example on the bottom, to allow the fibres access to a processing area, positioned between the silo 16 and the outlet pipe 14.
  • the silo 16 is formed of a ring-shaped wall that develops around silo axis S vertical with respect to ground level T on which the machine 10 rests, whereas the input pipe 12 develops primarily along the substantially horizontal axis of pipe C.
  • the fibres by falling and/or under the action of the airflow, pass from the silo 16 to the processing area.
  • the processing area comprises at least one pair of feeding wheels 20, 22, that rotate respectively around a first axis of rotation Z.
  • the rotation of feeding wheels 20, 22 is such as to convey the fibres that descend from the silo 16 down-line from said wheels, for example, counter-rotating.
  • the first feeding wheel 20, shown in figure 3 has a clockwise direction of rotation
  • the second feeding wheel 22 has an anticlockwise direction of rotation.
  • the feeding wheel 20, 22 comprises a plurality of profiles 24 that extend primarily along the first axis of rotation Z and comprise a bottom 26 and folded stretches 28, slanting with respect to the bottom 26.
  • the wheel 20, 22 is made by bringing together the bottoms 26 of the profiles 24 along an imaginary circumference, so that each bottom is tangent thereto, and making them mutually joined by uniting the folded stretches 28 thereof.
  • the two feeding wheels 20, 22, according to the variant represented, are positioned angularly and relatively to one another so that the imaginary radial extension of the cross member 32 of one of the two wheels 20 crosses the corresponding recess 30 of the other wheel 22.
  • the fibre fed by the silo 16 gathers in the recesses 30 of the feeding wheels 20, 22 and is taken down-line thereof undergoing a first channelling, due to the passage restraints made by the relative disposition of the wheels 20, 22.
  • the batt-forming machine 10 comprises an opening wheel 40, disposed down-line of the feeding wheels 20, 22, turning around a second axis of rotation W, substantially parallel to the first axes of rotation Z.
  • the second axis of rotation W is disposed between the first axes Z, so that the opening wheel 40 intercepts the fibre driven by the feeding wheels 20,22.
  • the opening wheel 40 comprises:
  • a support box 42 having a prevalent extension in an axial direction, for example, with a transverse section (orthogonal to axis of rotation W) polygonal, for example hexagonal, and
  • the protruding element 44 comprises a head 46, preferably disposed at the tip of the elongated element, protruding from the body thereof and disposed on the side of the direction of rotation of the opening wheel 40.
  • the fibre Whilst the fibre is fed by the feeding wheels 20, 22 down-line thereof, it encounters the protruding elements 44 of the opening wheel 40 that tears it into flock and subjects it to a kind of beating to facilitate the elimination of the polluting residues present in the fibre.
  • the batt-forming machine comprises a cleaning grid 50, disposed in a position suited to intercepting the fibred processed by the opening wheel 40.
  • the opening wheel 40 turns in an anti-clockwise direction and the grid 50 extends, at least partially, to the left of the opening wheel 40, to intercept the fibre processed by the same.
  • the grid 50 presents a processing wall provided with at least one evacuation opening 52 and distanced from the opening wheel 40 so as to make a gap 54, whose passage section preferentially tends to widen towards the direction of rotation of the opening wheel.
  • the evacuation openings 52 present an adjustable extension, according to the type of fibre being processed and in particular according to the desired degree of cleaning.
  • the grid wall 60 facing the opening wheel 40 intercepts the fibre drawn without accumulation by the opening wheel 40 in the gap 54.
  • the fibre therefore undergoes further beating and the residues, above all husks, separate from the fibre, falling therein, from where they are evacuated by means of aspiration.
  • the batt-forming machine comprises a chute 70, having a prevalent extension along a direction parallel to the axes of rotation Z, W.
  • the chute 70 presents an upper surface 72, forming a gap with the opening wheel 40, such as to extend the gap 54 formed by the grid with the opening wheel 40.
  • the upper surface 72 extends in the same direction of rotation of the opening wheel, so that the fibre processed by the grid is driven down-line of the opening wheel.
  • the upper surface 72 presents an extension beyond the second axis W, in the fibre movement direction to the outlet from the grid 50.
  • the batt-forming machine 10 comprises a driving roller 80, disposed down-line of the opening wheel 40 with respect to the fibre flow, and in particular disposed at the end of the chute 70, so that the fibre processed by the grid 50 falls on the driving roller 80.
  • the machine comprises a transit pipe 73, between the opening wheel 40 and the driving roller 80, delimited by containment walls.
  • the transit pipe 73 is defined by an area immediately down-line from the feeding wheels 20, 22, as far as an area immediately up-line of the driving roller 80, and extends completely between an upper height, defined by said area immediately down-line of the feeding wheels, and a lower height, defined by said area immediately up-line of the driving roller 80.
  • the pipe 73 does not present a "serpentine" course with subsequent stretches that occupy heights even greater than that of the area immediately down-line of the feeding wheels, to reach the devices for further processing in a position distant from the opening wheel.
  • the rotation speed of the driving roller 80 is such to avoid the accumulation of fibre in the area immediately up-line thereof, i.e. on the bottom of the pipe 73.
  • the containment walls of the transit pipe 73 comprise a strike wall 73a facing the opening wheel 40 and/or the chute 70, distant therefrom to allow the fibre coming out of the chute, driven by the protruding elements 44, to beat against it, and then fall on the driving roller 80.
  • the driving roller 80 turns around a third axis of rotation Y, parallel or otherwise to the other rotation axes W, Z.
  • the driving roller 80 is superficially covered, for example by a stiff saw-tooth covering to engage the fibre and draw it down-line.
  • the batt-forming machine comprises an opening roller 90, disposed down-line of the driving roller 80, turning around a fourth axis of rotation K, parallel to the axes W and Z.
  • the driving roller 80 and the opening roller 90 are preferably rotating in the same direction. According to certain embodiments, these are counter-rotating.
  • the cover of the opening roller 90 is fitted with a stiff covering, for example, with saw-teeth 91.
  • the cover of the opening roller 90 comprises a plurality of spikes 92, protruding from the external surface, able to penetrate into the wads of fibre and tear open the flocks thereof ( figure 4 , for illustration requirements, shows the roller 90 with both the covering and the spikes).
  • the teeth 91 and/or the spike 92 have a flock tearing action that reduces the compactness of the fibre, better preparing it for the subsequent cleaning processes.
  • the processing area of the batt-forming machine 10 comprises an outlet opening 100, disposed down-line of the cleaning roller 90, from which the open fibre is aspired, in communication with the outlet pipe 14 of the machine 10.
  • a work portion can be identified, between the area close to the conveyor roller 80, i.e. where the fibres pass from the conveyor 80 to cleaning 90 rollers, and the outlet opening 100.
  • the batt-forming machine 10 comprises at least one channelling flange 110, suited to pushing the fibre transported by the opening roller 90 towards the teeth 91, to improve the opening efficiency thereof.
  • Said channelling flange 110 is disposed around the opening roller 90, for example creating a fibre passage section radially decreasing in the direction of roller rotation, sufficiently close to the surface thereof to create a gap into which the fibre is channelled.
  • the flange 110 cooperates also with the driving roller 80, to prevent the cleaning roller 90 from tearing flocks that are too large.
  • the batt-forming machine 10 comprises at least one composite unit 121 comprising auxiliary devices such as an aspiration opening, a blade, a baffle, variably combined between them in relation to number and type, according to the processing requirements of the fibre or fibres being processed.
  • auxiliary devices such as an aspiration opening, a blade, a baffle, variably combined between them in relation to number and type, according to the processing requirements of the fibre or fibres being processed.
  • Said composite unit 121 is arranged along the work portion of the surface of the opening roller 90.
  • the composite unit 121 is contained in a box 121 a that can be detached or tilted from the machine cover.
  • the box 121 a can be tilted towards the exterior of the machine, performing a rotation that moves the cleaning roller 90 away, so as to make said roller accessible to maintenance technicians.
  • the box 121 a is hinged along a box axis C, disposed at a lower height than the rotation axis K of the cleaning roller 90.
  • the box axis C is disposed at a lower height of any generator of the cleaning roller 90.
  • such configurations allow easy access to the cleaning roller and the composite units for maintenance thereof.
  • the batt-forming machine 10 comprises at least two silos 16 facing the direction of the axis of pipe 12 and in the direction of fibre movement in said pipe 12.
  • Each silo 16 feeds a respective processing area, whereas the outlet openings 100 of said processing areas convey the processed fibre into the same joining pipe 120, connected to the outlet pipe 14 of the machine 10.
  • two batt-forming machines 10 are fed by the same inlet pipe 12 and the two outlet pipes 14 convey the fibre to the same fan 130, from which a further inlet pipe 12, leads to feed two further machines 10'.
  • the batt-forming machine 10 is devoid of the grid 50 ( figures 6 and 7 ).
  • the machine 10 comprises, in the processing area of the opening roller 90, a single composite unit 121 ( figure 5 ), comprising a single aspiration opening and a single blade.
  • the machine 10 is devoid, in the processing area of the opening roller 90, of composite units 121 ( figure 6 ).
  • the batt-forming machine 10 comprises a plurality of silos 16, each one independently fed by its own inlet pipe 12, 12', separated from the other ( figure 7 ). Said variant makes it possible to feed the batt-forming machine with different types of fibre.
  • the processing area fed by a silo is equipped differently to the processing area fed by another silo ( figure 7 ) and each silo is coupled with a respective fan.
  • the processing area of the first silo 16 includes a grid 50 and two composite units 121 in the work stretch of the opening roller 90, whereas the processing area of the second silo 16' does not include the grid 50 and does not include any composite unit 121 in the work stretch of the opening roller 90'.
  • Said variants with diversified equipment are particularly advantageous if one intends to obtain a mixture of natural (dirtier) fibres and synthetic (substantially clean) fibres of between natural fibres of different types or of synthetic fibres of different types.
  • the turning speed of the driving roller 80 is adjusted according to requirements, for example being different for each channel.
  • the batt-forming machine according to the present invention overcomes the drawbacks mentioned with regard to the state of the art and in particular with reference to the coupling between a mixer and a porcupine in a conventional batt-forming line.
  • the fibre, clean and in any case partially opened by the cleaning roller passes, without undergoing undesired compacting, to the transport roller - opening roller pair, which can process the fibre in more favourable conditions.
  • the adjustable grid makes it possible to perform more or less aggressive processing on the fibre, freeing it of the undesired residues and impurities according to the type of fibre.
  • the batt-forming line allows very extreme mixing, even when large volumes of fibre are being processed.
  • a stretch of a batt-forming line envisages a pipe feeding two machines of the kind described above, for a total of four silos.
  • each processing unit actually processes 300 Kg of fibre/hour, for the embodiments disclosed hereabove, which is then mixed together.
  • the box with the composite units can be replaced, making it possible to build machines suited to different fibres or mixtures of fibres, according to requirements, in a modular manner.
