Definitions

  • the invention relates to a device for limiting winding of a watch barrel comprising at least one non-return notch arranged to cooperate with a sliding flange that comprises the spring of the barrel, said barrel being integrated in a watch comprising a resonator cooperating with an escape mechanism.
  • the invention also relates to a device for winding a watch, comprising means for rewinding a barrel, and at least one such limiting device.
  • the invention relates to the field of rewinding watch barrels.
  • the difficulty consists in obtaining a correct value for the amplitude of the balance-spring whatever the watch and whatever the type of escapement (Swiss lever, coaxial or other).
  • the solution implemented consists in measuring the amplitude variation rather than its absolute value. When the watch is fully charged, the amplitude stops increasing. The winding mechanism then slaves the amplitude to a certain fraction of the maximum measured amplitude (for example 80%). This method works, but it has the disadvantage of having to wait for the amplitude to stabilize at a high value, which is difficult to detect, because the amplitude measurement is very noisy. This can take time, during which the winder winds the barrel to the point that the flange slips, and therefore creates wear.
  • the invention proposes to detect the complete winding of an automatic watch by identifying the noise made by the sliding flange in the barrel drum.
  • the invention relates more particularly to an intelligent winding mechanism with detection of noise from a sliding strap.
  • the invention relates to a device for limiting the winding of a timepiece barrel according to claim 1.
  • the invention also relates to a device for winding a watch, comprising means for rewinding a barrel, and at least one such limiting device.
  • the invention proposes to detect the complete winding of an automatic watch by identifying the noise made by the sliding flange in the barrel drum.
  • the invention relates more particularly to an intelligent winding mechanism with detection of noise from a sliding strap.
  • FIG. 1 shows a classic automatic barrel 1, and the picture 2 a barrel spring 4 comprising a sliding flange 3, before it is mounted in the drum 5 of this barrel, which comprises non-return notches 2 at its inner periphery, eight in number in the nonlimiting example illustrated.
  • This solution has the advantage of immediately identifying the moment when the watch is wound to the maximum, which minimizes potential wear. Moreover, the power reserve when the user removes his watch from the winder is potentially optimized compared to the method measuring the amplitude, since the maximum winding is identified with more precision.
  • FIG. 3 shows the acoustic signal as a function of time when the sliding flange enters the notch. This measurement was performed on a watch automatic ist 51 Swatch ® , hand-wound. This measurement shows that the acoustic signal from the sliding flange is particularly intense: it saturates even with the current sensitivity and gain settings. The noise of the winding system is also important: it partially masks the shocks of the escapement, however this does not pose a problem for an intelligent winder in which the rate and amplitude measurements are made when the winder is stationary.
  • the peaks P1 correspond to the shocks of the exhaust, the peak P2 corresponds to the noise of the sliding flange 3 in a non-return notch 2.
  • FIG. 4 shows the spectrogram of this signal (the temporal evolution of the frequencies).
  • the signature is particularly characteristic and clearly distinguishes itself from that of the noises of the escapement and the winding system, in particular in the frequency band between 0 and 2500 Hz. Two successive peaks P2 can clearly be distinguished.
  • the smart winder can advantageously keep a measurement of the amplitude, because this is the only one making it possible to identify any aging of the watch and the need for a return to after-sales service.
  • the two methods of analysis can coexist very well: the measurement of the noise of the sliding flange for the detection of the maximum reinforcement, and the measurement of amplitude for the evaluation of the long-term wear.
  • the measurement of the noise of the flange may, in a variant, not be systematic: the measurement of the noise of the flange can be used as initial calibration, for the qualification of the amplitude measurement. If a watch recognition system is implemented, the winder can assign a coefficient to the watch when it has been calibrated, thanks to the noise of the strap, and only use the amplitude measurement, which consumes less energy. electrical energy because punctual and not continuous.
  • the noise of the winding system can also depend on the winding, even before the flange slips, but the sound signature is differentiated, because the noise of the cooperation between the sliding flange and one of the notches is quite characteristic, and easy to isolate when processing the acoustic signal. It is then advantageous to have a low-power algorithm, which searches for and identifies the acoustic signature of such noise. It is also necessary to verify that this noise is similar regardless of the watch, or otherwise to qualify the characteristic winding noises and cooperation between the sliding flange and a drum notch, for each type of watch.
  • the invention thus relates to a winding limiting device 100 of a timepiece barrel 1.
  • This barrel 1 is integrated into a watch 1000 comprising a resonator 500 cooperating with an escapement mechanism 600.
  • the drum 5 of this barrel 1 comprises at least one non-return notch 2, which is arranged to cooperate with a sliding flange 3 that the spring 4 of the barrel 1 comprises.
  • the device 100 comprises acoustic means 10, for the acoustic monitoring of the winding of a barrel 1 of a watch 1000 positioned on a receptacle 20 which the device 100 comprises.
  • acoustic means 10 are arranged to identify a reference noise which is a snapping noise during each entry into cooperation between the sliding flange 3 and a notch 2.
  • the device 100 comprising control means 200, which are arranged to stop the winding of the barrel 1 at the moment of the perception of the click noise or the repetition of the click noise.
  • control means 200 are arranged to stop or prohibit the rearming of the barrel during the execution of a measurement by the acoustic means 10.
  • the acoustic means 10 are arranged to identify the reference noise of each input in cooperation between the sliding flange 3 and a notch 2.
  • control means 200 are arranged to memorize the maximum winding noise of a given barrel 1, and the reference noise, picked up by the acoustic means 10.
  • the acoustic means 10 are more particularly arranged to identify the noise of each input in cooperation between the sliding flange 3 and a notch 2.
  • the piloting means 200 advantageously comprise filtering means, so as to follow only the noise signals greater than or equal to the reference noise.
  • control means 200 are arranged to stop or prohibit the rearming of the barrel 1 when the acoustic means 10 pick up a noise greater than or equal to the reference noise.
  • control means 200 are arranged to stop or prohibit the rearming of the barrel the first time that the acoustic means 10 pick up a noise greater than or equal to the reference noise.
  • control means 200 are arranged to stop or prohibit the rearming of the barrel the second time that the acoustic means 10 pick up a noise greater than or equal to the reference noise.
  • the acoustic means 10 are arranged to evaluate the sound gradient during winding of the barrel, and the control means 200 are arranged to compare this sound gradient with a reference recording.
  • the acoustic means 10 are arranged to identify and/or to measure the amplitude variation of the resonator 500 by listening to the noises of the escapement mechanism 600.
  • control means 200 are arranged to stop the winding of the barrel 1 when the amplitude variation exceeds a predetermined threshold.
  • the invention also relates to a winding device 300 for a watch 1000, comprising means 400 for rewinding a barrel 1, and at least one such limiting device 100.
  • At least one such limitation device 100 is arranged to constitute means for initial calibration of a watch 1000, by measuring the reference noise of its sliding strap 3, for measuring amplitude or for measuring variation amplitude of the watch by the acoustic means 10.
  • the winding device 300 includes means 600 for identifying a watch 1000 for its calibration or its initial calibration.
  • the winding device 300 comprises rate and/or amplitude measuring means 700, which are arranged to measure the rate and/or amplitude on a watch 200 when the receptacle 20 carrying the watch 1000 is motionless.
