Definitions

  • the present invention relates to a device for moving a coil core or a coil having a closed shape with an inner contour and an outer contour as well as a winding machine equipped with such a device.
  • the winders are used to make coils from the winding of a conductor wire often copper and electrically isolated often by varnishing, around a ferromagnetic core including soft iron.
  • the coil of the geometry of the nucleus is closed on itself thus delimiting a passage opening.
  • the principle of these sensors lies in the variation of current generated by the passage of a metal bar inside the passage opening of the coil.
  • the coil of these sensors has most of the time a toroidal shape to allow the passage in its opening of a round bar or a rectangular bar according to product families.
  • This miniaturization requires changing the toroidal shape of the sensor coil and therefore requires a winder capable of winding a conductive wire around a core having a non-toroidal shape.
  • a winder used to wind a toroidal core comprises three rollers arranged around the core of the coil and coming into contact therewith.
  • At least one of these three rolls is driving and rotates the core at a constant speed to allow a shuttle passing through the core passage opening to wind the lead around the core section almost uniformly.
  • This advance device is satisfactory for the manufacture of toroidal-shaped coils but is not intended to accommodate a core having another shape, in particular an oblong shape.
  • This adaptation is to fix flat, according to its main plane, the core on a perforated plastic wedge at its opening to allow the passage of the shuttle.
  • the wedge is then placed between the three rollers whose spacing has been modified and moved in translation by at least one of them.
  • the document DE10146169A1 provides a solution for making a winding on a core having a non-toroidal shape and in particular an oblong shape.
  • This solution consists in using a belt to rotate the core or the coil.
  • the belt is tensioned by a set of rollers arranged judiciously so that it partially surrounds the core or the coil on its outer contour.
  • the rotational movement of the core generated by the belt does not maintain a constant distance between the shuttle and the core or the coil, which can cause distensions of the wire on certain parts of the belt. the coil, especially on the curved parts of the core.
  • the present invention aims to solve all or part of the disadvantages mentioned above.
  • the subject of the present invention is a device for advancing the movement of a coil core or a coil having a closed form with an inner contour and an outer contour characterized in that it comprises a first and a second roller movable in rotation about a respective axis and intended to bear against one of the two contours of the core or the coil, means for rotating at least one of the rollers, first retaining means associated with the first roll, the first retaining means being subjected to first return means arranged to bring the first retaining means of the first other of the two contours of the core or the coil, and the second retaining means associated with the second roller, the second retaining means being subjected to second return means arranged to bring the second retaining means of the other of the two outline of the core or coil.
  • This device also gives the core or the coil a revolution movement now at a substantially constant distance the coil or the core of the shuttle thus reducing the risk of distension of the wire on the core or the coil.
  • the retaining means are rotatable about the axis of rotation of their respective roll.
  • the device comprises two arms associated with each roller and each comprising a body on which are arranged the retaining means and the return means, said arms comprising means allowing the rotation of the retaining means around the axis of their respective roll.
  • the retaining means are movable in translation along an axis intersecting the axis of rotation of their respective roll.
  • the device comprises two arms associated with each roller and each comprising a body on which are arranged the retaining means and the return means, said arms comprising means allowing the translation of the retaining means along an axis. cutting the axis of rotation of their respective roll.
  • At least one of the arms comprises guiding means.
  • This arrangement makes it possible to maintain an arm so as to prevent it from getting in the way and impede the recessing of the shuttle wire during the advance of the core or the coil.
  • the two arms each comprise means for adjusting the return means.
  • This arrangement makes it possible to adjust the stiffness of the return means as a function of the thickness of the core section but also as a function of the number of overlaps and turns of the coil to be produced.
  • the body has a surface intended to ensure a sliding contact of the first roller 4a or the second roller 4b.
  • the device comprises a support wedge disposed on a fixed support and intended to ensure a sliding contact of the core or the coil.
  • This arrangement makes it possible to maintain the movement of the core or the coil in the same plane perpendicular to the axis of rotation of the driving rollers.
  • the drive means ensuring the rotational movement of at least one roller comprise a gimbal.
  • the drive means comprise a play catch system.
  • This arrangement eliminates the longitudinal play of the transmission that can be caused during its rotation and thus prevents a transmission break which would result in winding several turns at the same location of the core or the coil.
  • the play catch system comprises at least one spring.
  • the spring makes it possible to design an effective catch-up system at a lower cost.
  • a wedge is used to enhance the drive means to facilitate their movement.
