    State of the art
    Devices of this type for hunting display needles on watch movements are known.
    The operation to chase a display needle on a watch movement tree is difficult for many reasons.
    [0004] In the first place, there are generally several display hands on a given watch movement. Each of these needles must be hunted on a tree of its own and at a precise height and with a specific force to ensure its good performance on his tree.
    Moreover, a cleat is typically associated with a particular needle, in particular depending on the diameter of the shaft on which it must be driven. Thus, when a series of identical movements is assembled, these movements each having several needles, it is common to use a needle laying device comprising a pin for each needle, each pin carrying a given cleat associated with one of the needles to hunt. The pins are carried by a bracket whose upper part is rotatable to allow alternating positioning of the different pins above the watch movement, in order to chase the different needles one after the other.
    Therefore, in addition to the requirement for precision handling of the needles during their installation, the operations of changes of pins are tedious.
    Devices of this type are for example marketed by the Applicant and presented in particular on its website (http://www.voh.ch/pdf/flyer en / gallons needles.pdf).

    Brief description of the drawings
    Other features and advantages of the present invention will appear more clearly on reading the detailed description of a preferred embodiment which follows, with reference to the accompanying drawing given by way of non-limiting example and in which :<tb> fig. 1 <SEP> represents a schematic and simplified side view of a display needle setting device according to a preferred embodiment of the invention.
    Mode (s) of realization of the invention
    FIG. 1 is a schematic and simplified side view of a display needle setting device 1 according to a preferred embodiment of the invention.
    The device 1 comprises a base 2 in which are housed 3 central electronic circuits, including a microprocessor and a memory area (not specifically illustrated).
    The base 2 also comprises a support 4 for ensuring the establishment and maintenance of watch movement, through conventional positions 6 and on which needles will be driven.
    Moreover, the base 2 carries a bracket 8 carrying a pin 10 near its free end.
    The pin 10 is integral with a shaft 12 mounted in the bracket 8 so as to be able to move vertically, either towards the support 4.
    A button 14 is provided for the handling of the pin 10 in a conventional manner, as well as a return spring 16 to keep the pin 10 in its upper position, that is to say remote from the support 4.
    A stop sensor 18 is also carried by the bracket 8 to detect the low position of the pin 10 when actuated by an operator.
    An inclined arm 20 extends from the bracket 8, towards the pin 10.
    The arm 20 serves as a support for a barrel 22 fulfilling the function of a distributor cleats 24 for pin 10. In fact, the barrel 22 has a plurality of housing each of which is intended to carry a cleat 24 well defined , especially associated with a well-defined clock-watch clock-gauge couple.
    The barrel is thus rotatably mounted on the arm 20 so as to occupy different predefined angular positions and present one of the housings in the path of the pin 10 in each of the predefined angular positions. Thus, the barrel, by its rotation, makes it possible to select one of the different cleats to be assembled on the spindle depending on the display hand and the watch movement concerned.
    When the desired cleat 24 is located opposite the pin 10, the latter can be actuated by the operator to go down towards the support 4. On the path, the pin 10 engages the cleat and the causes in its race to the vicinity of the support, at a defined height, to perform the hunting of a given needle by action of the cleat on the needle and its shaft, in a conventional manner.
    When the spindle 10 is released, it rises under the effect of the action of the return spring 16, replacing the cleat 24 in its housing on the barrel 22 during its rising stroke.
    Each watch clock-gauge pair having its own characteristics in terms in particular of the driving height, it is expected to adjust the height of the pin 10 according to the working torque concerned.
    More specifically, it can be provided for example that the device comprises a member 26 for automatic adjustment of the height of the spindle 10, including including motor 28 whose operation is controlled by the electronic circuits 3. It is illustrated here, schematically, the fact that the motor 28 causes the rotation of a belt 30 itself driving a threaded bushing 32 whose rotation changes the height of the pin 10 in its upper position, thereby influencing its low position.
    It can also be provided that the adjustment member 26 comprises an additional mechanism 34 for manually adjusting the height of the spindle 10.
    An additional motor (not shown), or possibly the motor 28, is able to act on the barrel 22 to rotate on the basis of instructions generated by the electronic circuits 3, in order to position the mandrel required next to spindle 10.
    The arm 20 also carries, illustratively non-limiting, a light source 36, controlled by the electronic circuits and able to point the driving position of a given display hand on a given watch movement. For example, it can be provided that the light source projects a pattern on the watch movement to facilitate the relative positioning between the pin 10 and the watch movement during the driving of a needle.
    Furthermore, it can also be provided that the device 1 comprises an interface for the operator. Thus, it may have in particular a screen 38, data entry keys, indicator lights 40, or possibly an electrical connection 42 for connecting the electronic circuits 3 to an external memory or a computer.
    In addition, it is possible to provide that the device comprises an identification member 44 of the connection connected to the electronic circuits, in order to make the implementation method of the device even easier. Thus, on the basis of the identification of the clock caliber on which one or more needles must be driven, the barrel can be automatically positioned in the required angular position, without further intervention of the operator on the device.
    It can also be provided that the device comprises a force sensor 46 arranged to measure the force applied to the support 4 from the pin 10, when placing a display needle on a watch movement.
    In this case, it can also be provided that the electronic circuits are arranged tostore in the memory reference values of the force applied to the support 4 from the pin 10, during the installation of a given display hand on a given watch movement,comparing the results of the measurements made by the force sensor 46 with the stored reference values, andto indicate to the operator information relating to the result of the comparison between the results of the measurements made by the force sensor 46 and the stored reference values.
    With these characteristics, a first quick check of the quality of laying the needle is performed directly by the device according to the invention, by measuring the applied force.
    It is clear from the present description that the device according to the invention provides a significant time saving to perform the display of the needles with reference to the known devices of the prior art, while ensuring levels of accuracy and very high reliability.
    The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and, the invention is not limited to the implementation of certain particular features which have just been described, as for example the combination of all the additional sensors which have been mentioned in a non-exhaustive manner and by way of nonlimiting illustration.
    The skilled person will not encounter any particular difficulty in adapting the content of the present disclosure to his own needs and implement a display needle setting device including a body performing the function of a distributor of cleats for a spindle.
