Definitions

  • the present invention relates to a device for loading needle boards of felting or structuring machines.

  • a filling device is provided, which separates using a pair of parallel augers felting needles from a supply and in a matching, the pitch of the needle board corresponding distance provides so that the needles in groups seized with the multiple collet and then can be used simultaneously in the needle board.
  • the needles clamped in the multiple collet may to some extent deviate from the desired parallel orientation. This may be because the needles have been gripped by the multiple collet in non-parallel alignment or the needles have slight bends. As a result, deviations in the position of individual needle tips can occur both within a plane defined by the clamped needles and perpendicular thereto.
  • an insertion aid for inserting a plurality of needles into a needle board of a structuring or felting machine is provided.
  • the needles are clamped together in a multi-collet and preferably arranged parallel to each other in a row.
  • the distance of the needles preferably corresponds to the pitch or the distance of the associated, arranged in a row holes in a needle board to fully assemble them. But it could also be chosen larger needle spacings, leaving a portion of the holes unoccupied.
  • the needle board bores typically have a narrow diameter to securely hold a needle after press-fitting. Accordingly, when inserting, the tolerance to the aforementioned position deviations of the tips of the clamped needles is low.
  • the insertion device has a plurality of grooves for receiving in each case one of the needles clamped in a multiple collet chuck.

  • the guide section 32 at the end which is associated with the rows 12 of the bores 11, a flattened end 64.
  • the grooves 51, in particular the edges 52 terminate in the narrow end 63 preferably formed as an end face.
  • the recesses 51 and optionally their edges 52 terminate at the end face 63 above and at a distance from the needle board 10.
  • an insertion device 20 with a guide portion 32 according to Fig. 9 to be set at a distance a to a row of holes 12, so that the tip 45 of a needle 41 finds its associated hole 11.
  • This has the advantage that the needle board 10 can be moved in the x-direction without introduced needles 44 colliding with recesses of the insertion device 20, as is the case with insertion devices 64 with pointed ends.
  • a distance b is present, which is smaller by half the diameter of the bore 11 than the distance a. Due to the distance b, it is possible to equip the insertion device 20 a complete row of holes 12 without the position of the insertion to change.
  • the guide portion 32 of the insertion device 20 can provide a guide during placement, due to its length, only a portion of the needles 41 of a row of needles. After insertion of these needles 41, the needle board 10 is moved in the x direction to introduce more needles. This process is repeated until a row of holes 12 is completely provided with needles. Thereafter, the insertion device 20 can be offset and the next row of holes 12 are again provided by means of several insertion operations with needles 41.
  • An insertion device 20 is provided which makes it easier for an operator to simultaneously insert many needles 41, 44 clamped in a multiple collet 40 into the associated bores 11 of a needle board 10, even with certain positional deviations.
  • the insertion device 20 has a guide portion 32 with many parallel grooves 51 which are arranged at a distance of the holes 11 and each record the tip 45 of a needle 41, 44 and can lead to the associated bore 11.
  • the grooves 51, the individual needles 41, 44 help to align the holes 11 by correcting any positional deviation by slight bending of the needles 41, 44.
  • the insertion device 20 is mounted on a placement machine 1 and based on a recorded in this needle board 10 adjustable and lockable.
