Definitions

  • Control unit with electromagnets in particular for actuating the dobbies for weaving machines.
  • the present invention relates to a control device comprising a series of electromagnets intended for the selective actuation of a corresponding number of movable members arranged in superposition or side by side at a regular interval, in particular elements of a dobby for weaving machine
  • the frame preferably made of aluminum in order to have great rigidity while ensuring good thermal conduction for the evacuation of heat, is profiled along the wings of its U-shaped transverse profile so that the cover, provided with longitudinal bosses, can be fixed to said frame by simple snap-fastening.
  • the reference 1 designates a metal frame, of aluminum or of cast aluminum alloy, the length of which is equal to that of the control block to be produced and therefore depends on the number of electromagnets thereof.
  • this frame 1 has a U-shaped profile in cross section, the inner face of each branch being hollowed out with a longitudinal depression la.
  • the transverse edges of the bottom of the frame 1 are arranged to allow easy attachment of the entire control unit; in the exemplary embodiment envisaged, it has been assumed that these edges were pierced with holes Ib for the passage of screws or bolts.
  • the frame 1 is provided with reinforcing ribs which improve its rigidity and which determine ventilation channels facilitating the evacuation of the heat in the ambient air.
  • a cover 2 also made of aluminum or a light alloy based on aluminum.
  • Each of the side walls of this cover 2 has an external boss 2a which extends longitudinally to snap into place, by means of momentary elastic deformation, inside the corresponding depression 1a of the frame 1.
  • the bottom of the cover 1 is cut out. of two parallel rows of openings 2b, established with a flattened rectangular profile oriented transversely with respect to the axis of the cover; into each pair of transversely aligned openings 2b are introduced the ends, forming poles 3a, of the two branches of a soft iron core 3, with the usual U-shaped profile.
  • each core 3 On one of the branches of each core 3 is engaged the tubular support 4 of a coil 5; the lateral cheeks of this support 4 bear against the bottom of the core 3 and against the internal face of the cover 2, thus opposing the movement of said core towards the outside, while its movement towards the inside is limited by bearing against a positioning plate 6.
  • the latter is fixed against the edges of the cover 2 and it extends over the entire length of the base thereof; it will be noted that this plate 6 is cut out from a series of central windows 6a with a rectangular profile elongated transversely, in each of which is housed a boss 3b formed on each of the cores 3. '
  • each coil 5 is connected by connections 7 to a printed circuit 8 applied against the underside of the positioning plate 6; this circuit 8 is itself electrically connected to a common power cable 9 housed between said circuit and the bottom of the frame 1.
  • the fixing of the printed circuit 8 against the plate 6 and of the latter against the open base of the cover 2 is advantageously ensured by the pins 7, the protruding ends of which are welded against the aforementioned circuit after crossing it and the plate.
  • the free interior space of said carcass is filled with a mass 10 of resin synthetic injected through appropriate openings, said mass 10 filling all the voids left between the cores 3, the coils 5, the plate 6, the cable 9, etc.
  • a compact block is therefore finally obtained, having perfect rigidity while being capable of dissipating in a particularly effective manner the heat released following an intensive operation of the windings 5.
  • the constituent elements are positioned precisely, so that the filling operation cannot disturb the construction.
  • the invention makes it possible to produce a unit of monobloc, independent and waterproof electromagnets, connected to an electronic control panel by a single cable, so that in the event of a breakdown, it suffices to disconnect this cable and remove the device to replace it Maintenance of the equipment is thus considerably simplified.
