Definitions

  • the invention relates to a method and a device for loading and despiring needle boards of felting machines with felting needles.
  • Felting machines serve to densify fibrous webs of disordered fibers, such as nonwoven webs (with and without backing material), and occasionally also for aftertreatment of woven or knitted fabrics.
  • the felting machines have a substantially planar support, which is provided with a large number of felting needles.
  • This carrier is also referred to as a needle board.
  • the felting needles sit in corresponding openings, into which they hold with their holding part are pressed.
  • the term "felting needle” used here also includes needles which are used for the aftertreatment, eg roughening or perforating of knitted or woven fabrics.
  • the Utility Model DE 83 29 050 U1 discloses a pick and place machine with a felting needle magazine. This is positioned above a needle board. The openings present in the needle board can be detected by suitable optoelectronic sensors. The needles can then be transferred from the magazine into the holes via a corresponding mechanical drive.
  • a device for inserting and ejecting needles of a needle board known.
  • the machine has a movable frame that can be positioned above a needle board.
  • An ejection punch provided on the device can be moved vertically by motor force to press on the needle tips thereby releasing the needles from their seats.
  • the same machine is used to press felt needles loosely inserted into a needle board into the needle board.
  • a multiple collet chuck is used to simultaneously grasp several felting needles and insert them into corresponding openings of the needle board.
  • the felt needles are held at a distance that coincides with the hole spacing of the needle board.
  • an automatic manipulator or a corresponding trained worker by means of the multi-collet each insert a whole group of felting needles in the needle board.
  • rows of holes can be equipped with needles in just a few steps or a few operations.
  • a corresponding pressing device can then press the needles of a row of holes in a single stroke in the needle board.
  • the collet is designed so that it can hold the individual felting needles in almost any distance, ie in any division.
  • the felting needles are clamped eg between two smooth jaws.
  • the multiple collet is associated with a filling device adapted to receive the group of felting needles to be received by the multiple collet the pitch to be available, which is also present on the needle board.
  • one of the clamping jaws has recesses which correspond to the predetermined pitch of the filling device. The depth of the recesses is less than the needle thickness, so that the needles arranged in the recesses can be clamped by the second clamping jaw with its smooth inner side.
  • the filling device removes the needles, for example, a needle container, in which a large number of corresponding felting needles, however, loose aligned, ie, for example, are parallel and directionally equal to each other.
  • a corresponding workstation equipped for fitting needle boards preferably has the following components for carrying out the method: a holding device for the needle board to be loaded, said multiple collet, a filling device for filling the multiple collet, and an injection device which serves the felting needles inserted into the needle board to press into the needle board.
  • a transport device is additionally provided, which serves to transfer the needle board from a loading position to the press-in device. This significantly facilitates the work of equipping a needle board.
  • the filling device specifies the needle pitch. Under Nadelteil the distance between the felting needles within a row, which is arranged parallel to the longitudinal side of a needle board is to be understood.
  • the filling device may for this purpose have two threaded spindles whose pitch corresponds to the desired needle pitch.
  • the needle pitch and the spacing of the needle rows of a needle board can be detected with a camera or other sensor device.
  • the threaded spindles can be replaced manually, for example.
  • the machine control may prompt the operator to remove the threaded spindles that are suitable for the detected pitch from a supply and insert them into the filling device.

This results in the opposite foot orientation. The worker may alternatively use the filling device 51 or the filling device 51a.
  • the threaded spindles 52, 53 division If he wants to change the predetermined by the threaded spindles 52, 53 division, he can replace the threaded spindles 52, 53. A corresponding spindle stock is kept ready at the placement semi-automatic machine. By appropriate positive couplings he sets the threaded spindles 52, 53 in accordance with the desired rotational position in the filling device 51 a. The insertion of the threaded spindles can be done in accordance with a screen prompt that outputs the machine control according to the detected with the image pickup device 44 division.
  • An insertion machine for needle boards 2 has a filling device 51, which presents felting needles 17 in a pitch which coincides with the hole pitch of a needle board. A worker can take the felting needles 17 with a multiple collet 45 and insert them into the rows of holes of the needle board 2 in groups. This results in a loading process with very high productivity.
