Definitions

  • the present invention is in the field of motor spring mechanisms and relates more particularly to an automatic winding installation of a timepiece with motor spring.
  • the invention aims to allow the automatic winding of motor spring mechanisms, which is particularly advantageous for timepieces with many functions, in order to avoid the tedious work of adjusting the time, date and phases moon, etc. when the watch is not wound regularly every day.
  • Patent CH-16.114 a machine is described, the rotation of which is controlled manually when the watch winder is brought into contact with a rotary cleat.
  • Patent CH-118,494 proposes a watch composed of several movements and a device making it possible to wind them simultaneously.
  • the rotation drive means are controlled periodically, in a predetermined manner, by a timepiece disposed in a control unit which is connected to a rotation control device, said rotation control device being constituted by a disc having openings capable of cooperating with measuring means, and in that the timepiece is placed on a setting.
  • buttons or crowns with devices comprising a common control installation, which is particularly advantageous for stores having both different timepieces.
  • Figure 1 is a schematic top view of the main components of an automatic winding installation.
  • FIG. 2 is a side view, with partial section, of certain elements shown in FIG. 1.
  • Figure 3 shows a variant of the drive part.
  • Figure 1 the main components of the winding installation according to the invention, namely a housing 10, a gear 20 and a support 30 in which are arranged a coupling device 40, a control device 50 and connecting means 60 to a specific adapter for each type of watch.
  • the timepiece to be wound is shown diagrammatically by a wristwatch 70, placed on a setting 80.
  • the installation may include a control clock 90.
  • an electronic control unit 11 comprising a timepiece and a motor for rotating a shaft 12.
  • the housing 10 comprises a power outlet 13, intended to be connected to the network .
  • On the upper face 14 of the housing are arranged the mechanical elements for driving the winding in rotation, which are protected by a cover 15 shown in dashed lines in the drawing.
  • the housing 10 further comprises pushers 16, 17 respectively enabling the time of the clock 90 to be set and the control of the rotational drive movement of the timepiece.
  • the electric motor 12 drives a gear 20 consisting of two conical wheels 21 and 22 giving a shaft 23 a unidirectional rotational movement.
  • a support 30 intended on the one hand for fixing the protective cover 15 and on the other hand for maintaining the mechanical elements driven in rotation.
  • the support 30 has a U-shaped section, the two parallel wings 31 and 32 each having an opening 33 and 34 for the passage of the rotary shafts. It goes without saying that each opening 33 or 34 can receive a bearing, not shown in the drawing.
  • the coupling device 40 consists, in the embodiment shown in the drawing, by a friction drive coupling, with fixed or adjustable torque, comprising two discs 41 and 42. It should be noted that in the variant shown the relative position of the coupling device 40 relative to the central shaft 43 can be adjusted, thanks to the thread 44 provided at the end of the shaft 43 and intended to cooperate with a tapping provided in the hub 45 of the disc 42. The end 46 of the shaft 43 opposite the thread 44 cooperates with a spring 47 to allow adjustment of the length of the assembly and further includes a radial peg 48, the usefulness of which will be mentioned later.
  • the central shaft 43 rotates the disc 51 which is part of the control device 50.
  • the disc 51 has a series of openings 52 arranged in a crown and intended for the passage of light rays which can be picked up by a photoelectric cell, shown diagrammatically in 53.
  • the connecting means 60 are constituted by a tubular part 61 intended to rotate in the opening 34.
  • the part 61 has at one end a central clearance 62 making it possible to accommodate the spring 47 as well as a longitudinal slot 63 for the passage of the piton 48 intended to give the part 61 the rotary movement of the shaft 43.
  • a clearance 64 At the other end of the part 61 is provided a clearance 64 in which is fixed an adapter 65 intended to cooperate with the winding crown 71 of the watch 70.
  • the tubular connecting piece 61 is shown in the drawing in one piece, but it can be replaced by several elements ensuring the same functions, without departing from the scope of the invention.
  • a wristwatch is shown diagrammatically in the drawing, but it goes without saying that the installation according to the invention also extends to the reassembly of parts of different dimensions, for example pocket watches or any other type of motor spring mechanism. , the relative movement of the tubular part 61 relative to the central shaft 43 making it possible to adapt the installation to different diameters of timepieces.
  • the adapter 65 can be made of elastomeric material, intended to drive the winding crown by friction by pressing on the outer face of the latter. As shown in the variant of FIG. 3, one can also provide an adapter 66 comprising a thumb wheel 67 intended to drive a winding crown 72 by resting on the periphery thereof, this variant being more precisely used for parts watchmaking whose crown is partially embedded in the carure. As a variant, it is also possible to provide an adapter matching the shape of the crown.
  • the timepiece 70 to be wound is placed on a setting 80 having upwards a circular clearance 81 and comprising at least one foot 82 allowing the height to be adjusted according to the arrow 83, as a function of the thickness of the watch and the position of the winding crown.
  • the fitting comprises an elastic element, for example a spring 84 allowing easy fitting of the watch.
  • the winding assembly according to the invention will in principle operate once a day, for four to five minutes.
  • the protection means preventing the overvoltage of the spring act by blocking the winder the disks 41 and 42 of the friction coupling device 40 become detached.
  • the disc 42 and therefore the central shaft 43 remain stationary, as does the control disc 51.
  • the photoelectric cell 53 no longer picking up the signals passing through the openings 52, the electronics 11 stop supplying the motor d training 12.
  • each installation will be adjusted for a timepiece, by choosing the appropriate adapter 65 or 66 to act on the winder.
  • the relative positioning of the drive disc 42 relative to the central shaft 43 will be adjusted so that the friction force between the discs 41 and 42 is such that, when the winding of the mainspring is carried out, the means of protection preventing overvoltage provided in the timepiece exert a force greater than that of friction between the discs.
  • the visible parts will, for example, be made of wood or leather.
  • control electronics for driving several motors corresponding to different timepieces, a variant which will preferably be adopted in stores having both different timepieces.
