Definitions

  • the present invention relates to a brush conveyor. It also targets a needling machine equipped with this conveyor.
  • Velvet needle looms have a brush conveyor which has the function of carrying and driving a sheet of textile fibers under a steel plate called stripper and provided with perforations through which a set of needles alternately penetrate into the sheet and into the conveyor brushes.
  • the articulated brushes of this conveyor receive during the needling, within their tufts of bristles, fibers driven by the needles and thus contribute to the production of a textile product having a velvet type surface condition.
  • the brushes of substantially parallelepiped shape, are oriented and aligned perpendicular to the direction of travel of the sheet of fibers. These alignments create lineages in the direction perpendicular to the travel of the web. In addition, the clearances between the brushes create lines in the other direction.
  • the object of the invention is to remedy these drawbacks by proposing a brush conveyor which makes it possible to obtain a textile product having a isotropy of surface better than that obtained with existing conveyors, and to suppress lineages.
  • the brush conveyor comprising an assembly of contiguous brushes constituting a conveying plane moving in a predetermined conveying direction, each brush comprising a body of substantially elongated shape along a main axis and comprising on its lower face means for connecting the brush to a mechanical drive device and on its upper face holes for receiving tufts of bristles and arranged in rows substantially parallel to the main axis, is characterized in that the brushes are arranged within the conveyor so that their main axes are parallel and inclined at a predetermined angle relative to the direction perpendicular to the conveying direction.
  • the brushes are no longer aligned in the direction perpendicular to the movement of the product. It becomes possible to provide for a regular implantation of the tufts of hair while avoiding creating alignments of tufts which would be parallel or perpendicular to the direction of conveying or scrolling, experience having shown that the existence of such alignments contributed to the birth of product marking defects.
  • the brush conveyor further comprises, under the drive device, a set of belts driven by motorization means, and under the means of mechanical connection of the brushes to the drive device, a set of connecting rails arranged perpendicular to the conveying direction and integral with the belts, each ra l being designed to receive a transverse row of contiguous brushes.
  • Each brush further comprises, at its body, a slide arranged to receive a connecting rail, this slide being oriented relative to the main axis of the brush so that the brush has an angle of inclination predetermined by relative to the axis perpendicular to the conveying direction.
  • a velor needle loom comprising needling means provided for causing a set of needles to penetrate in a reciprocating fashion through a sledgehammer into a sheet of fibers supported and driven by a conveyor brushes according to the invention.
  • FIG. 1 is an exploded perspective view of a conveyor comprising inclined brushes, for a needling machine according to the invention
  • FIG. 2 is a perspective view of an example of a brush used in a conveyor according to the invention.
  • FIG. 2A shows a first example of assembly of inclined brushes of the type shown in Figure 2 for a conveyor 1 according to the invention
  • FIG. 3 shows a second example of inclined brushes for a conveyor according to the invention
  • FIG. 4 illustrates a particular mode of attachment of a brush according to Figure 2 within a conveyor according to the invention
  • FIG. 5 illustrates a particular mode of attachment of a brush according to Figure 3 within a conveyor according to the invention.
  • FIG. 6 illustrates a third example of inclined brushes for a conveyor according to
  • a brush conveyor 1 may comprise, by way of nonlimiting example, two drive cylinders 2, 3 provided for driving several belts 5, 8, 9. To these belts are fixed connecting rails 4, 6, 7 arranged transversely with respect to the direction of movement or of conveyance D. These rails each cross a row 100-104 of contiguous brushes transversely.
  • the assembly 10 of the conveyor brushes produces between the two drive cylinders 2, 3 a conveying plane P for which the least possible clearance is sought between contiguous brushes in order to obtain an irreproachable surface condition for the needled product. .
  • FIG. 1 For the sake of clarity in FIG. 1, only the bodies of the brushes have been shown.
  • these brush bodies have an elongated hexagonal shape and are designed to allow easy interlocking of contiguous bodies and so that the rotation of the transverse rows of brushes does not pose any problem at the level of the drive cylinders 2, 3.
  • a brush body 11 on which tufts of bristles 120 are normally implanted is surrounded at most by six other brushes.
  • Each brush body has a main axis AI inclined at an angle ⁇ relative to the transverse direction AT perpendicular to the direction of movement D. In practice, this angle of inclination can be chosen to be less than 10 degrees.
  • a brush 21 comprises a body 29 comprising on its upper face a set of holes
  • This slide preferably comprises lateral housings 280, 281 designed to receive keys when all the brushes of the same transverse row have been coupled to the connecting rail.
  • the axis of this slide is parallel to the transverse direction AT perpendicular to the direction of movement D, while the main axis AI of the brush, to which the longitudinal rows of receiving holes are parallel, is inclined to it by the angle d incl inclination with respect to the transverse direction AT.
  • the main axis AI of the brush to which the longitudinal rows of receiving holes are parallel
  • the body 29 is of elongated hexagonal shape and includes corrugated side walls 22, 23, 24, 25, 26, 27 which are flush with the receiving holes located at the periphery of the body 29. These walls side provide somehow a form of locking contiguous brushes between them without hampering the rotation thereof around the drive cylinders.
  • the receiving holes can be arranged on the upper face of a brush body 21 at the nodes of a centered hexagonal network, so that each hole is equidistant from its neighbor, as illustrated in FIG. 2A which partially represents a plane of conveyor 20 consisting of a set of inclined brushes of hexagonal shape.
  • These inclined brushes have a main axis AI which constitutes the common direction of the longitudinal rows of receiving holes and is inclined by an angle of inclination ⁇ relative to the transverse direction AT.
  • the main axes Al, A2 With the hexagonal arrangement of the holes and the inclination of the brushes, the main axes Al, A2,
  • a conveying plane 30 consists of the assembly of brushes with two body shapes.
  • a first body shape 31 is rectangular, this body comprising on its upper face rows of longitudinal holes parallel to the main axis AI of the brushes which is inclined by an angle of inclination ⁇ relative to the transverse direction AT.
  • a second body shape 36 comprises a rectangle of the same dimensions as those of the first body shape to which is added an additional row of truncated holes 360 comprising for example one hole less than the other rows.
  • the side walls 32-35, 37-39 are smooth and the receiving holes are arranged on the upper face of each brush so that they occupy the nodes of a square network.
  • a brush body 40 having corrugated side walls 41-46 comprises, with reference to FIG. 4, a recess 403 over the entire length of this body 40.
  • This recess has a main axis AI inclined relative to the axis transverse AT and acts as a slide to receive a connecting rail 400 of the profiled type and keys 401, 402 in suitable housings.
  • An equivalent method of attachment can be used for brushes whose body 56 has parallel and smooth longitudinal side walls 53, 56 and ends of substantially triangular shape, the corresponding side walls 51, 52, 54, 55 being crenellated to adjoin the receiving holes located at the periphery of the body, this body 56 also has a recess 57 provided for receiving a profile-type connecting rail and keys in appropriate housings 58 , 59. the main axis of this recess AI is also inclined relative to the transverse axis AT.
  • the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention.
  • the number of rows and holes on a body can be arbitrary and is not limited by the present invention. It is the same for the number of brushes and the organization of these brushes.
  • the angle of inclination can be chosen according to considerations of the quality of the needled product on the basis of tests or simulations.
  • holes of any shape in particular holes of circular, elliptical or else oblong shape, and various methods of fixing the tufts of bristles within the holes of the brush bodies, for example, by stapling, gluing , or by welding.
