Description

Field of the invention

The invention relates to a device for chronological control of the movement of a watch or watch movement, said device comprising at least one receptacle arranged for holding, up to a given acceleration threshold, at least one movement or movement. a watch, and comprising maneuvering means arranged to maneuver in space each said receptacle, arranged to impose on each said receptacle at least one predefined or random cycle as to its trajectory and its dynamic evolution along this trajectory under control control means comprising a clock or connected to an external time base, said cycle comprising the passage through the normalized positions of time control.

The invention also relates to a method for dynamic time control of watch movement, or watch.

The invention relates to the field of chronometric controls for mobile timepieces, watches and chronometers of marine or edge.

Background of the invention

Chronometric control of a timepiece, particularly a watch, or its movement, is essential to verify the quality of the product delivered to the user. This control is governed by official certification standards, established by recognized laboratories or observatories, which are essential for the placing on the market of products.

Current chronometric controls measure the properties of the watch in static positions. Classically static controls are performed in six control positions, two horizontal and four vertical.

Manufacturers are also interested in different intermediate positions in space, which seem more representative of the actual wear of a watch. For example, the collective work "Théorie d'horlogerie" by MM. Reymondin, Monnier, Jeanneret, Pelaratti, published by the FET (Federation of Technical Schools) in Switzerland, page 158, figure 7.85, quotes in the vertical position 8 hours at the top with inclination at 30 °.

The document of the International Chronometry Congress 2007, in Colombier (Switzerland), page 45, issued by MM Meissner, Pellet, Müller, Gervaise, Meylan, thus mentions automated measurement cycles in the 6 reference positions, plus the intermediate positions. at 45 °.

The device "cyclotest" is a machine used to raise and maintain lifts mechanical watches with an automatic winding system. The watch is positioned on a rotating device which permanently maintains it in a dynamic movement. The watch tends to fall behind when placed on this device. This device is commonly used by watchmakers to keep the watch in function. Typically, the watchmaker notes the time of the watch and a reference time, places the watch on the device "cyclotest" or in a static position on his workbench typically 24h, note again the reference time and the displayed time and deduces from it the value of the walking drift of the watch (this measurement corresponds to the daytime running).

The Rolex document EP 3 136 189 A1 on behalf of ROLEX describes a time measurement method and more particularly on the positions in which the watch or watch head is positioned during the measurement. Chronometry controls simulate, through static positions, the various positions of the watch during the day of a typical wear.

The document EP10192725 on behalf of The Swatch Group Research & Development Ltd. describes chronometric qualifications by optical methods.

Summary of the invention

The invention aims to define time control criteria to accurately qualify the watches produced, and to set up adequate tools and control methods.

To this end, the invention relates to a device for dynamic time control of watch movement, or watch, according to claim 1.

The invention further relates to a method for the dynamic time control of watch movement, or watch, according to claim 14.

Detailed Description of the Preferred Embodiments

The invention proposes to differentiate the usual static positions, and dynamic movements, and, for this purpose, to define a chronometry criterion corresponding to a concept of "dynamic position".

It is understood that, during the same day, a watch that is worn by a user, can occupy static positions sometimes extended (for example, placed on a desk during the day, or on a night table during the night, or still during the day when the wearer reads a book or is without physical activity, traveling for example) and can occupy an infinity of positions at other times, during phases where the watch is constantly changing position, by example when the wearer walks: this concept of "dynamic position" corresponds to this continuous movement.

By analogy, we can simplify the approach of the invention, by imagining a watch placed in a carousel of type big eight, which is resting 12 hours a day in vertical, and made loops during the remaining 12 hours (with statistically 6 hours head up and 6 hours upside down).

• 18 heures en position « vertical haut », correspondant au total des 12 heures du repos et des 6 heures pendant lesquelles statistiquement la montre est dans cette position durant les loopings) ;
• 6 heures en position « vertical bas », correspondant aux 6 heures où la montre est statistiquement dans cette position durant les loopings ;
• la montre ne devrait alors pas présenter de dérive de plus de ± 2 secondes par jour.

A traditional chronometric certification would consist in certifying the march as follows:

• 18 hours in "vertical high" position, corresponding to the total of 12 hours of rest and 6 hours during which statistically the watch is in this position during loops);
• 6 hours in the "low vertical" position, corresponding to the 6 hours the watch is statistically in this position during loops;
• the watch should not drift by more than ± 2 seconds per day.

• 12 heures en position « vertical haut » ;
• 12 heures en « position dynamique » (de type looping) ;
• la montre ne doit pas présenter de dérive supérieure à une certaine valeur, de plus de ± x secondes par jour.

Whereas, according to a "dynamic position" type certification according to the invention, it would consist in certifying the step as follows:

• 12 hours in "vertical high"position;
• 12 hours in "dynamic position" (looping type);
• the watch must not show drift greater than a certain value, more than ± x seconds per day.

• un relevé avec un accéléromètre au poignet fournit un relevé des accélérations subies par la montre. Il est possible de définir un critère, par exemple un seuil d'accélération, qui permet de différencier les positions statiques des mouvements dynamiques ;
• les positions statiques sont pondérées selon les 6 positions horlogères habituelles ;
• la/les positions dynamiques peuvent être définies selon les accélérations relevées sur des porteurs. Par exemple, une position dynamique peut reproduire de manière précise le mouvement d'une montre lorsque le porteur marche. Une autre position dynamique peut reproduire tous les autres mouvements aléatoires de la journée (s'habiller, boire, manger, ou autre...) ;
• dans la position dynamique, la montre est constamment en mouvement ou accélérée, sans pour autant n'être que simple succession de positions statiques ;
• cette position dynamique est valable également pour des montres sans remontage automatique ;
• le déplacement exact appliqué à la montre peut être, à volonté, programmé, ou totalement aléatoire ;
• le déplacement exact peut être imposé et défini précisément. Par exemple, la montre peut être sur un dispositif « cyclotest » avec lequel la trajectoire de la montre est connue ;
• le déplacement peut reproduire un porter statistique, et peut aussi comporter un passage obligatoire par certaines position intermédiaires pré-définies, paramétrables ;
• la vitesse du déplacement appliqué peut être variable ou constante ;
• la variation d'autres paramètres physiques, comme non limitativement la température et la pression atmosphérique, ou l'hygrométrie, ou autre, peut être combinée avec les déplacements imposés au mouvement ou à la montre ;
• la mesure des propriétés chronométriques (marche et amplitude) peut se faire en continu sur le dispositif dynamique, ou via une mesure d'état (lecture de l'heure) avant et après la période en « position dynamique ».

This is to define this "dynamic position", in particular according to the following points:

• a reading with an accelerometer on the wrist provides a record of the accelerations experienced by the watch. It is possible to define a criterion, for example an acceleration threshold, which makes it possible to differentiate the static positions from the dynamic movements;
• the static positions are weighted according to the 6 usual watch positions;
• the dynamic positions can be defined according to the accelerations recorded on carriers. For example, a dynamic position can accurately reproduce the movement of a watch as the wearer walks. Another dynamic position can reproduce all the other random movements of the day (getting dressed, drinking, eating, or whatever ...);
• in the dynamic position, the watch is constantly moving or accelerated, without being merely a succession of static positions;
• this dynamic position is also valid for watches without automatic winding;
• the exact movement applied to the watch can be, at will, programmed, or totally random;
• the exact displacement can be imposed and precisely defined. For example, the watch may be on a "cyclotest" device with which the trajectory of the watch is known;
• the displacement can reproduce a statistical bearing, and can also include a mandatory passage by certain pre-defined intermediate positions, parameterizable;
• the speed of the applied displacement may be variable or constant;
• the variation of other physical parameters, such as non-limitatively temperature and atmospheric pressure, or humidity, or other, can be combined with movements imposed on the movement or the watch;
• measurement of the chronometric properties (walking and amplitude) can be done continuously on the dynamic device, or via a state measurement (reading of the time) before and after the period in "dynamic position".

The invention thus makes it possible to characterize the chronometric properties of the watch in a more precise manner and more faithful to the wear / need of the customer.

The invention thus relates to a device 1 for dynamic chronological control of movement 2 of watch 3, or of watch 3. This device 1 comprises at least one receptacle 4, which is arranged to hold it in complete safety, up to a threshold of given acceleration, of at least one movement 2 or a watch 3.

These control means 10 comprise storage means 30, which are arranged to store tolerance parameters, value thresholds, and / or to store parameters of duration and physical conditions representative of particular bearing-types, and are this effect advantageously coupled with these environment sensor means 8 and with environment generating means 80, which are arranged to impose particular physical conditions where the measurement takes place: temperature, hygrometry, magnetic field, or other.

More particularly, these random number generation means 14 are arranged to impose on the control means 10 a random duration of this interruption.

In a variant, the control means 10 are arranged to resume the predefined or random cycle according to the position reached during the interruption, at the end of the interruption. In a particular variant, the end of the interruption is managed by the clock 6 of the device 1.

More particularly, this multi-axis robot 21 has three axes at the level of the shoulder joint 22 (abduction-adduction movements in the frontal plane, and flexion-extension in the sagittal plane), and at least one axis at the elbow joint 23. However, the complex movements of supination and pronation of the forearm, in the transverse plane, can be approximated, as far as the effect for a watch 3 worn on the forearm abutting against the protruding ulna, three robot axes at the elbow.

In a particular variant, the same receptacle 4 includes several movements 2 or watches 3, is arranged to be manipulated by a robot, and includes positioning marks for the precise identification of its positioning in the space, and comprises orifices arranged for the passage of sensors and / or adjustment means.

In short, the invention allows a better knowledge of the behavior of a watch movement or a watch during all phases of its use. Additional checks performed against traditional repositories have a significant counterpart in favor of the user. The design of a device 1 according to the invention makes it possible to carry out useful control operations during phases that were once unproductive transition phases, and improves the overall quality provided to the customer.

The extensive automation of this production-control station also makes it possible to carry out a thorough control of the running of a watch movement on the basis of dynamic positions only, in fact the provision of a certificate according to static positions. is not always required, and it is not necessary to immobilize the movement or the watch during the corresponding period, because the dynamic chronometric controls are an excellent way of qualifying a production.
