Definitions

  • the object of the present invention is a method as well as a machine for winding and fixing the ends of a wire more particularly intended for winding large series of miniaturized coils as commonly used in recording and reading devices of the its for example.
  • the main aim of the present invention is to allow pseudo-continuous operation of the winding machines for increase the production rate.
  • winding method according to the present invention which consists in mounting one or more winding mandrels of the "flyer" type on a frame so as to be movable in three directions orthogonal to this frame as well as to be able to be driven in rotation relative to this frame and to move linearly step by step at least one coil facing this mandrel.
  • the winding machine for implementing the process described is distinguished by a frame, electro-mechanical means making it possible to move one or more winding mandrels of the "flyer" type in three orthogonal directions and in rotation about their axes with respect to to said frame, as well as by a feed device moving linearly step by step a series of coils facing said winding mandrels.
  • the present method of winding and fixing a wire to the terminals of a coil consists in mounting one or more winding mandrels of the "flyer" type with respect to a fixed frame or base such that these winding mandrels perform relative to this frame all the relative displacements, linear along three orthogonal axes X, Y, Z and rotary around their axis, necessary for the winding and the fixing of the wire, and to move linearly step by step a series of coils opposite of these winding mandrels, the displacement of the coils serving only for the supply of the coil bodies and for the extraction of the finished coils; this displacement of the coils occurring between two successive winding operations.
  • This winding machine for implementing the described method is illustrated, schematically and in an embodiment by way of example, in the accompanying drawing.
  • This winding machine comprises a frame 1 or fixed base intended to be fixed to the ground or on a support.
  • This frame 1 has a support 2 on which is mounted a first electric motor 3, for example a stepping motor, driving by means of a toothed belt 4 and gears 5,6 a lead screw 7 pivoted in a support 8 secured to the frame 1.
  • a first electric motor 3 for example a stepping motor, driving by means of a toothed belt 4 and gears 5,6 a lead screw 7 pivoted in a support 8 secured to the frame 1.
  • This lead screw 7 cooperates with a nut 9 secured to a table 10, mounted on the frame 1 using slides 11.
  • a nut 9 secured to a table 10, mounted on the frame 1 using slides 11.
  • This table 10 comprises a support 12 on which is mounted a second electric stepping motor 13 driving in rotation, by means of a toothed belt 14 and pinions 15,16, a second mother screw 17 pivoted in a support 18 secured to the table 10.
  • This second lead screw 17 cooperates with a nut 19 secured to a frame 20 mounted to slide on said table 10 by means of slides 21.
  • a rotation of the motor 13 drives the frame 20 in a corresponding linear movement relative to the table 10 along the direction Y orthogonal to the direction X of movement of the table 1 relative to the frame 1.
  • the frame 20 includes a support 22 on which is mounted a third electric stepper motor. step 23, driving a third mother screw 27 in rotation by means of a toothed belt 24 and pinions 25,26.
  • This third lead screw 27 is pivoted in a support 28 secured to the frame 20 and cooperates with a nut 29 secured to a slide 30 sliding on the frame 20 by means of slides 31.
  • Any rotation of the third motor 23 causes a corresponding linear displacement of the slide 30 relative to the frame 20 in a direction 2 orthogonal to the directions X and Y.
  • This slide 30 carries a block 41 in which are pivoted several winding mandrels 32 with axes mutually parallel and parallel to the direction Y of movement of the frame 20.
  • Each of these winding mandrels or “flyer” comprises an eccentric thread guide 33 through which the wire is unwound during the winding operation.
  • the rotary axis of the mandrel 32 comprises two pinions 34, 35, one connected by a toothed belt 36 to pinions carried by the rotary axis of each of the other mandrels and the other connected to a pinion. 37 by a belt 38, pinion 37 driven in rotation by an electric motor 39 for example of the stepping type, fixed on a support 40 integral with the block 31.
  • the motor 39 for example of the stepping type
  • the block 41 carries a base 42 on which the winding mandrels 32 are pivoted along axes parallel and parallel to the direction Z of movement of the slide 30.
  • the motor 39 is mounted on this base and its pinion 38 directly drives all the pinions 43 respectively fixed to each rotary axis corresponding to a mandrel 32, by a belt 44.
  • FIG. 7 schematically and partially illustrates a device for feeding and extracting the coils.
  • This device comprises a guide 50 disposed opposite the mandrels 32 in which slides a conveyor belt 51 provided with holes each receiving a coil body 52 provided with an input terminal 53 and an output terminal 54.
  • a device d The drive formed by rollers 55, 56 makes it possible to cause the conveyor belt 52 to advance over a desired distance, corresponding to the replacement of the wound reels by the same number of reel bodies to be wound.
  • This supply and discharge device is pseudo continuous and can be placed either horizontally if the mandrels are vertical or vertically if the mandrels are horizontal.
  • the conveyor belt 52 can be replaced by a support band coming from an injection or molding part with the bodies of coils to be wound.
  • the winding machine also includes, for each mandrel 32, a thread breaker 45 fixed to the slide 30.
  • Blank reels can be loaded on pallets for transfer to and from the winding position.
  • the machine described can constitute a work station, the winding station, of a complete installation for manufacturing coils.
