Definitions

  • the present invention relates to a needling machine used to mechanically consolidate a layer of fibers for example from a lapper spreader.
  • Known needling machines have a support called a board on which needles are attached. At connecting rod-crank devices, the board is reciprocated so that these needles cross the fiber web at a rate that can go into production from 1000 to 2000 rounds per minute.
  • Complementary devices allow also to regulate the incoming fiber flow and leaving the machine with or without stretching and at speeds chosen according to the striking rate in number of strokes per minute, equivalent to the number of alternative movements of the hands per minute.
  • each connecting rod-crank device extends between a eccentric connected to a motor, and a joint to the end of a sliding rod to which is attached a needle board support.
  • the sliding rod crosses two bearings sliding located at a certain distance one of the other as described in document US-A-4,884,324.
  • This arrangement has the disadvantage that the bearings are strongly loaded radially in one direction which is always the same, namely the direction of the lateral reaction force that appears between the connecting rod and the rod because of the angle formed between them, taking into account the angular movement of the connecting rod around its axis of articulation with the rod. It is especially the level which is closest to the joint that is the most loaded, typically five ten times more than the other.
  • These bearings undergo their maximum load, with a tendency to brace the stronger the incline is inclined, when the rod pushes the rod to penetrate the needles in fibrous products. Furthermore, in in some cases the tensile forces of the product not woven are transmitted to the needles when they are are embedded in the product.
  • the object of the present invention is thus to suggest a needling machine in which the problem of the wear of the sliding bearings is clearly lessened.
  • the needling machine shown in Figure 1 includes a perforated table 1 generally horizontal and a retaining plate 2, also called “stripper", placed approximately parallel to a certain distance above table 1.
  • Table 1 and stripper 2 define a path between them in a plane substantially horizontal for a sheet of fibers 3.
  • the stripper 2 includes perforations aligned with those in table 1.
  • introducer means 4 shown schematically in the form a pair of motor rollers between which the tablecloth 3.
  • extractor means 6 also shown diagrammatically by two motor rollers between which the tablecloth passes.
  • the stripper 2 is placed between the path of the tablecloth 3 and a needle board 7.
  • Board 7 carries side of stripper 2 a large number of needles 8 oriented perpendicular to the plane of the path of the tablecloth 3, with their point directed towards tablecloth 3.
  • Each needle is positioned opposite a perforation of stripper 2 and a perforation corresponding from table 1.
  • the needle board 7 is fixed, on the side opposite the needles 8, to a support 9 itself attached to the end of at least one rod 11 sliding ascent along an axis 12 parallel to needles 8 and perpendicular to the plane of the path of the tablecloth 3. If several rods 11 are provided, these are for example aligned one behind the other when viewed as shown in the figure 1.
  • each rod 11 is guided in two stages of sliding coaxial 13 and 14, axially spaced.
  • the bearings 13 and 14 are made integral, by means which will be described later, of a casing 16 which is not only partially shown. Landings 13 and 14 have anti-friction rings 17 for contact with rod 11.
  • the mobile equipment consisting of the rod (s) 11, the support 9 and the board 7 is animated in service with an alternating movement of going and comes in direction 12 between a position 7a in which end of the needles, designated in this case by 8a, crosses the stripper 2, the sheet 3 and the table 1, and a release position 7b in which needles 8 are completely free at least from the table 1 and tablecloth 3, and possibly stripper 2.
  • the rod 11 is articulated by a articulation 18 at one end of a connecting rod 19 of which the other end is connected by a hinge 21 to a crank 22 rotated by means motors not shown.
  • the two bearings 13, 14 are joined to one another by being formed on a common tubular mount 41 which is coaxial with rod 11 and which can be adjusted angularly around the axis 12 of the rod 11 relative to the casing 16.
  • the anti-friction rings 17 are fixed in the frame 41.
  • the casing 16 has through a lower wall facing the support 9 a circular orifice 42 centered on axis 12.
  • Mount 41 is mounted through the orifice 42 and has a centering flange 43 in hole 42.
  • the frame 41 is terminated by a flange 44 comprising for example six fixing holes 46 regularly angularly distributed around the axis 12, intended for receive six clamping means 47, such as bolts, engaging in corresponding holes in the housing 16.
  • the clamping means 47 are dismantled, rotate the frame for example 60 ° equivalent to an integer of times the step of succession of the clamping means 47 around the axis 12, and the clamping means are replaced.
  • the rod 11 comprises at from its end 27 facing the connecting rod 19, a first region 28 having an outer wall cylindrical which is slidably engaged in that of bearings 13 and 14 which is closest to the crank 22.
  • the rod 11 further comprises a second region 32 which has a smaller diameter than the first region 28.
  • the cylindrical outer wall of the second region 32 slides in the bearing 14 which is closest to needle board 7, which has a smaller diameter than the bearing 13.
  • the bearing 13, which is the busiest in service, has a considerably increased diameter which makes it particularly resistant to wear.
  • the force F transmitted by the connecting rod 19 when it is inclined relative to the rod 11 has a transverse component F T which tends to ovalize the bearings 13 and 14 according to a diameter parallel to the angular plane of movement of the connecting rod 19
  • this ovalization reaches an excessive degree, the frame 41 is angularly adjusted with respect to the casing 16, as has been said above, so that the force F T is now exerted on the bearings 13 and 14 according to diameters of those - which have not yet been enlarged by the ovalization phenomenon.
  • the two levels could be independently adjustable one of the other. It is still possible that only one of the bearings, for example bearing 13 which is the most requested, or adjustable.
  • each bearing by means of a bore comprising an appropriate surface treatment, for example a bore made directly in the material of a swivel mount also corresponding to the frame 41.
  • the invention is applicable to all types needling machines, especially table needles perforated as described, but also needling manufacture of velvet, loop product etc ...
