Definitions

  • the present invention relates to a conveyor brushes. It also targets a needling machine equipped with this conveyor.
  • Document FR-A-2 217 460 discloses a needling machine comprising an endless band lined with bristles which leans under a set needling, on a horizontally movable pad providing a support function.
  • This endless strip can be made up of separate links articulated between them and playing the role of supports for the bristles. This configuration is not suitable for needling machines equipped with a conveyor comprising a set of brushes contiguous and does not actually solve the problem encountered with a double brush tilting movement during needling and cleaning.
  • the object of the invention is to remedy these disadvantages by offering a brush conveyor for a velvet needle loom which allows to obtain a isotropic product without lineage.
  • a brush conveyor comprising a set of contiguous brushes arranged in transverse rows, means for driving this set of brushes so as to constitute on the face upper part of the conveyor a conveyor plan according to predetermined direction of movement, each brush comprising a body comprising on its upper face holes provided to each receive a tuft of hair and on its underside, means for connecting this brush to the training means, these means drive comprising several belts or chains parallel drives placed between at least two drive cylinders and whose direction is common and this conveyor including in addition to means for directly supporting the bodies of brushes constituting the conveying plane.
  • the support means include a support table with multiple flat support parts separated by spaces to receive the belts or drive chains, and each transverse row of brushes is associated with a connecting rail extending over the entire depth of the conveyor, arranged perpendicular to the direction of displacement and fixed to belts or chains training.
  • the play of the brushes is considerably reduced during needling.
  • the brush bodies are both maintained transversely with respect to each other thanks to the connecting rails and at the same time supported vertically by a support table.
  • the conveyor further comprises means for holding the brushes constituting the conveying plane against the support table so the undersides of the bodies of these brushes are kept in constant contact with the support parts, which is not at all the case on current systems.
  • the holding means may include means of magnetic attraction, and the undersides of brush body and support table include parts of ferromagnetic material.
  • the support table has perforations and that the holding means include ways to create depression at through the perforations of the support table.
  • a velvet needle loom including a conveyor brush according to one of the preceding claims and means for needling a supported sheet of fibers and driven by the conveyor, these needling means cooperating with the conveyor brushes to drive fibers of the web in the tufts of hair of these brushes.
  • a brush conveyor 1 comprises a device drive not including example two cylinders 15, 16 around which are placed belts 3-6 or any other equivalent means such as Chains.
  • the movement of these belts defines a direction of movement D and the upper plane space existing between the two cylinders 15, 16 constitutes a conveying plane P which has the function of supporting and to entrain a layer of fibers during the operation needling.
  • This conveyor plan includes a set 2 brushes 120, 130, 140, 150, 160, 170, 180 arranged in transverse rows 200, 201, 202 perpendicular to the direction of travel D.
  • brushes 120, 130, 140, 150, 160, 170, 180 have their bodies 122, 132, 142, 152, 162, 172, 182 in contact direct with a substantially flat support table S and horizontal, and the tufts of hair 121, 131, 141, 151, 161, 171, 181, 32 regularly implanted in holes receptors 33 on the upper surfaces of the brushes realize a homogeneous and isotropic whole in which the needles will penetrate alternately.
  • the support table S consists in practice of several support parts 7, 8, 9, 10 separated by spaces or interstices extending parallel to the direction of travel D and designed to accommodate drive belts 3, 4, 5, 6 which in practice are flush with the support parts.
  • the bodies 122, 132, 142, 152, 162, 172, 182 of the brushes are joined by a connecting rail 30 ( Figure 2) common to the assembly brushes and itself attached to the drive belts by fixing devices 20.
  • the brushes 25, 26, 27 of this conveyor each have a recess made in the level of their underside and making slide, extending longitudinally in the main axis of each brush and designed to receive a connecting rail 30 having in practice a profiled type structure.
  • a row of brushes 27, 25, 26 is formed by inserting the connecting rail 30 into the recesses respective, keys 22, 23 are then inserted in force or not in appropriate housing within recesses to maintain and secure all of the brush body in a row.
  • the 25 brushes find themselves at the base of a separating space between two support parts 7, 8 have at their face lower a device 20 for fixing the whole body brush / rail connecting to the drive belt 3 located in the separator space considered.
  • This space separator preferably has a width significantly less than the length of a brush so that the brushes 25 located above the space separator still have on their underside sufficient contact surfaces with the parts of support 7.
  • the brushes 26 which are not located at the above a separator space do they have the whole face lower in contact with the support part correspondent 7.
  • Each fixing device 20 has a length substantially equal to the width of a belt 3,, in reference to Figures 2 and 4, so that it does not hinder not the circulation of this belt within the space separator. It includes a part 43 inserted in a free space inside the connecting rail 30 and made integral with the latter by three rods transverse 40, 41, 42. This part 43 is provided for receive two nuts 24, 28 corresponding to two screws 21, 27 coming to tighten the belt 3 on the one hand, a tooth 29 of the belt pierced with two holes for the passage screws and placed under the belt 3, and secondly, the underside of the connecting rail 30. This device fixing 20 thus makes it possible to fix the connecting rail 30 to the belt 3.
  • the other brushes are also driven by the mechanical connection of the brushes on the same transverse row which is provided by the presence of the connecting rail. With this method of attachment, the undersides of the brush bodies 27, 25, 26 may be in direct contact with parts of support 7, 8, which contributes to significantly improving the stability of these brushes during needling.
  • a first embodiment of this maintenance involves implementing well-known effects of magnetic attraction.
  • the effects of magnetic attraction between the magnets and the ferromagnetic table will generate attraction forces of substantially normal direction on the support table plan.
  • permanent magnets 56 are arranged in the interior space 50 of the connecting rail 30, the support table 55 being always made of material ferromagnetic.
  • magnets 56 are also arranged at inside the connecting rail 59, the latter and the brush bodies being arranged to receive keys 58/1, 58/2 having a circular section. This embodiment offers the advantage of catching up automatic lateral play.
  • a fourth embodiment of active maintenance brushes against the support table consists in setting works an attraction by depression, as illustrated by figure 6.
  • a vacuum generating device 67 includes suction equipment is arranged under a support table 65 provided with perforations 66.
  • a depression is thus created on the surface of the support table 65. This depression must be adjusted for ensure correct maintenance of the brush bodies 61 at the during needling operations.
  • the holding means 52, 53; 67 cooperate with the means link 50; 60 to ensure the greatest stability to the brush bodies when subjected to both drive forces transmitted by the belts and by the connecting rails and alternative forces needling.
  • the brush conveyor 1 which has just been described can be advantageously used in a needling machine velvet, but it can also be used in other industrial equipment requiring an area of conveyor having a brush-like surface condition.
  • the invention is not limited to the examples which have just been described and numerous arrangements can be brought to these examples without departing from the framework of the invention. So we can consider many other arrangements for the realization of the means of maintenance.
  • the optimal arrangement of permanent magnets can be determined based on electromagnetic calculations.
