Definitions

  • ABSTRACT Apparatus for simultaneously winding a plurality of coils in a machine having a single stationary coil support and a single rotary wire guide shaft, comprising a support body mountcd on the single shaft through a bearing and carrying a plurality of rotatable secondary wire guide shafts to which the rotation is imparted through an assembly of constantly meshing gears and a gear fast with the single wire guide shaft.
  • the present invention relates to an apparatus adapted to be fitted to coil winders of the type having a rotating wire guide, to permit the simultaneous winding of a plurality of coils to be effected.
  • An example of such a coil winder is described in my Italian Patent No. 739,109 and my corresponding U.S. Pat. No. 3,402,903.
  • the cores are mounted on fixed pins, which may be carried by a turret adapted to revolve by steps in which case the wire guide operates at one of the fixed positions of the turret; with this arrangement, it has not been practically possible heretofore to achieve the simultaneous winding of a plurality of coils because of the difficulties of a technical nature in effecting synchronized control of the rotating and translating movements of the wire guides.
  • the principal object of the present invention is to solve this problem in a manner which, both from the constructional and from the functional point of view, is extremely simple.
  • an attachment for simultaneously winding a plurality of coils in a machine with a stationary coil or single support and a longitudinally reciprocating rotary shaft for a wire guide comprising a support body which in use is mounted on the rotary shaft by means of a bearing, said bearing constraining the body to move longitudinally with the rotary shaft but without rotating therewith, the support body carrying a plurality of rotatable but non-slidable wire guides drivably interconnected through an assembly of constantly meshing gears with a gear fast with the said wire guide shaft.
  • the attachment according to the invention is moreover designed to permit an increase in the winding rate on coil cores of small diameter, so as to achieve an exceptional increase in the productivity of the machine.
  • FIG. I is a diagrammatic side view of a coil-winding machine to which the apparatus according to the invention can be fitted, 7
  • FIG. 2 is a side view, partly in section, of the apparatus of the invention.
  • FIG. 3 is a diagrammatic front view thereof.
  • the attachment according to the invention is fitted to a coilwinding machine of appropriate type, for example that described in my Italian Patent No. 739,109 and my corresponding U.S. Pat. No. 3,402,903, having a'frame with a turret 29 and with a wire guide 52 mounted at the-end of a rotatable and slidable shaft 53 and a coil core 30 mounted on a fixed pin opposite the shaft 53.
  • the attachment embodying my present invention can be employed with a wide variety of coil-winding machines of the type having at least a single stationary coil core support and a rotating and axially sliding wire guide, said attachment allowing for the simultaneous winding of a plurality of coils on said coil-winding machine.
  • the coil-winding machine essentially involves a base 21 which supports the annular structure 22 provided with radial holes 23. In the holes 23 are fastened the support shafts of the operating stations; of these only the hollow shaft 24 of the winding head fastened by means of the screw 25 is represented.
  • the frame 26 of the support carousel of the coil to be wound On the structure 22 is further fastened the frame 26 of the support carousel of the coil to be wound.
  • the shaft 27 which constitutes the free rotating pin of the rotary table 28, provided with the crown 29 support a series of coil forms of plugs 30; the rotary table 28 is also designed to support accessories adapted to carry out particular working on the coils formed on the plugs 30.
  • the intermittent rotation of the table 38 is generated by the knob 33 supported by the shaped disc 34, which is caused to rotate via the gears 35, 36, 37, 38 by the motor 39 provided with brake 40.
  • the knob 33 drags the table 28 by means of radial cavities provided on its lower part, for example by a Maltese cross advancement system and subsequent locking; at the end of each dragging cycle the table 38 is stopped by the mechanical switch contactor 42, which has the dual function of breaking off the current from the motor 39 and of energizing the motors of the operating stations, particularly the motor 43 of the winding head.
  • the head driving system is constituted of a two-speed motor 43 with brake 44, which may oscillate on its support axis 46 for tensioning the belt 47 between the two cones of the pulleys 48 and 49 constituting the variable transmission.
  • the shaft 53 of the wire guide is rotatable with the pulley 51 but sliding in relation thereto.
  • the sliding shaft 53 is thrust by the spring 53' to its backward position so as to maintain the pin 54 of the collar 55 constantly in contact with the rod 56.
  • the collar 55 is freely rotatable, but axially locked in relation to the shaft 53 by backing means, so that it follows the shaft 53 in its axial displacements, but remains locked in the rotation by the action of a plug (not represented) which slides in a groove 58 of the frame.
  • the rod 56 is pivoted in 58' on the slider 59 and locked via the oscillating sleeve 60 on the semifixed slider 61.
  • the sleeve 60 ensures both the oscillation and the free axial sliding of the rod 56, and hence does not prevent the slider 59 from sliding over the track 62.
  • the locking between rod 56 and sleeve 60 equally ensures manual displacement of the semifixed slider 61 in relation to the graduation 66; in this way, it is possible to vary the ratio between the spaces run by the slider 59 and those run by the pin 54, that is by the wire guide assembly.
  • the setting of the position of the slider 61 is made with the aid of the small shaft 63, provided with a control knob 63' and a pinion 64 meshing with the stationary rack 65'and is controlled in relation to the graduated scale 66.
  • the slider 59 is set in motion by the pin 67 carried by the lever 68, to which is associated a cam-follower (not represented) in contact with a control cam, against which it is maintained by the load of the spring 53 through 55,54, 56, 59, 67.
  • the apparatus or attachment embodying the present invention essentially comprises a body 3, preferably of light alloy,
  • the body 3 is mounted at the end of the shaft 53, in place of the wire guide 52, by means of a bearing 5; this bearing permits free rotation of the shaft 53 with respect to the body 3.
  • a fixed bar 4 projects from the wall of the frame 41 and engages in a groove 3 in the body 3 to act as a stabilizing means by securing the body against any rotation, while permitting longitudinal displacement of the body 3 along the axis of the shaft 53; it is obvious that, inversely, the bar 4 may be secured to the body 3 to engage a recess of the frame 41 to accomplish the same result.
  • the bearing 5 moreover forms an axial keying means for the body 3 on the shaft 43, so that the movements of the latter in the axial direction are followed faithfully by the body 3.
  • the shafts 6, 7, 8 and 9 are mounted so that they are rotatable but not axially slidable in the body 3; rotary movement is transmitted to the shafts 6, 7, 8 and 9 through gears 10, l2, l4 and 16 integral therewith and meshing with a series of intermediate gears 11, 13 and 15.
  • the gear 13 is directly secured to the shaft 53, which serves to rotate the shafts 6, 7, 8 and 9.
  • the transmission ratio of the assembly of gears may be selected to obtain the required speed of the shafts 6, 7, 8 and 9.
  • each of the shafts 6, 7, 8 and 9 there is associated a wire guide 17 supplied independently with wire 18 by conventional guide pulleys.
  • the hollow shafts 6, 7, 8 and 9 are of limited length so as to permit even capillary wires to be inserted easily.
  • a support frame 20 secured to the turret 29 carries a series of fixed pins, one corresponding to each of the wire guides 17, the pins being adapted to hold the cores 19 on which the winding is to be effected.
  • the number of turns and their law of distribution are determined by the rotatable and slidable shaft 53 in known manner, taking account of the transmission ratio obtained through the gears to 16.
  • the present invention permits the winding of small-diameter coils at high speed. Assuming that the transmission ratio from the shaft 53 to the shafts 6, 7, 8 and 9 has, for example, a step-up of four and that, as shown, four coils are wound simultaneously instead of one, an increase in the productivity of the machine ofsixteen times is obtained.
  • the bar 4 may if desired project from the body 3 (instead of from the frame 41) engaging in a recess in the frame.
  • An attachment for simultaneously winding a plurality of coils in a coil-winding machine of the type having a series of coil core supports stationarily mounted on a step-by-step advancing turret and a longitudinally reciprocating rotary shaft for a wire guide said attachment comprising: a support body; bearing means rotatably mounting said support body on said rotary shaft, said bearing means adapting said support body for longitudinal movement with said rotary shaft; stabilizing means for preventing said support body from rotating with said rotary shaft; a plurality of rotatable but non-slidable secondary wire guides carried on said support body; and an assembly of constantly meshing gears mounted proximately to said support body, said gears interconnecting said secondary wire guides, one of said gears being fast with said rotary shaft.
  • the attachment of claim 1 further comprising a secondary attachment for the turret of said coil winding machine, said secondary attachment comprising: a series of fixed core carriers, said carriers being mounted on said turret for serial movement into register with said support bodies; a plurality of supporting pins for the coils to be wound mounted on each core carrier, said supporting pins being disposed in alignment with said plurality of secondary wire guides carried on said support body.
  • said stabilizing means comprises an aperture in said support body and a bar fixed on the frame of said machine, said bar being aligned with said aperture so as to engage same in order to permit free axial sliding ofsaid support body while preventing rotation thereof.
  • said stabilizing means comprises a bar mounted on said support body and a corresponding recess provided in the frame of said machine, said bar being aligned with said recess so as to engage same in order to permit free axial sliding of said support body while preventing rotation thereof.
  • An attachment for simultaneously winding a plurality of coils in a coil-winding machine of the type having at least one stationary coil core support and an axially reciprocating rotary shaft for a wire guide said attachment comprising: a support body; bearing means for rotatably mounting said support body on said rotary shaft, said bearing means al owing said support body to move longitudinally with the rotary shaft; stabilizing means for preventing said support body from rotating with said rotary shaft; a plurality of rotatable but non-slidable secondary wire guides carried on said support body; an assembly of constantly meshing gears mounted proximately to said support body, said gears interconnecting said secondary wire guides, one of said gears being fast with said rotary shaft; and secondary support means associated with said stationary coil core support, said secondary support means supporting a corresponding plurality of coil cores.
