    [0001] The invention relates generally to vibratory systems. The invention also relates to vibrating machines for screening materials and / or supplying materials that comprise vibratory systems.
    [0002] Vibratory systems comprising two unbalanced shaft lines are known from the state of the art. Each unbalanced shaft line comprises a rotary shaft and an unbalance module mounted to rotate with said shaft. The shaft lines are rotated to generate vibrations used to screen and / or advance the materials. However, the rotational drive of unbalanced shaft lines of systems known in the state of the art, requires significant energy. In addition, when stopping the rotational drive, the vibration frequencies generated may include values corresponding to the resonant frequencies of certain parts of the machine. In particular, the vibration frequency can be close to the resonance frequency of the damping elements on which the frame of the machine is mounted.
    [0003] The object of the present invention is to propose a new vibratory system and a corresponding vibrating machine making it possible to reduce the energy required to drive unbalanced shaft lines and / or to reduce the risk of degradation of all or part of the machine.
    [0004] For this purpose, the subject of the invention is a vibratory system for a screening and / or supply machine, the vibratory system comprising shaft lines, each shaft line comprising an unbalance module, said vibratory system comprising also a drive device configured to drive the shaft lines in rotation synchronously and in the same direction; characterized in that said vibratory system also comprises an angular modification device configured to modify the angular position of the unbalance module 3033270 2 of a shaft line with respect to the angular position of the unbalance module of the other line of tree or one of the other tree lines. In other words, the angular modification device makes it possible to modify the relative angular position of the unbalance modules with one another in the case where the vibratory system comprises two rows of shafts, or to modify the relative angular positions of the unbalance modules, one by to others in the case of a larger number of tree lines, for example three, four or more. The relative angular position of the unbalance modules is referred to as the angular configuration of the unbalance modules. By way of example, a given angular configuration of the unbalanced modules can be represented in the case of n-lines of trees in the form of a (n-1) - angle angle tuplet, each angle value of the n-tuple, corresponding to the angular phase shift, that is to say the difference in angular position, of the unbalance module of a line with the unbalance module of the adjacent line. The angular orientation axis of an unbalance module is defined as the cutting axis orthogonal to the axis of rotation of the unbalance module and passing through the center of gravity of the unbalance module. The angular position is an unbalance module corresponding to the angle formed by the angular orientation axis of the unbalance module relative to a reference axis orthogonal to and intersecting the axis of rotation of the unbalance module. Once a first reference axis of an unbalance module of a shaft line has been defined, the reference axis of the unbalance module of each other line is an axis which is orthogonal to, and intersecting, the axis. of rotation of the unbalance module of said other line and which is parallel to said first reference axis. The device may be configured to rotate the unbalance module of one, several or each shaft lines, according to the expected number of shaft lines, to modify the angular configuration of the unbalance modules of the lines of tree.
    [0005] Such a design of the vibratory system according to the invention for which the unbalanced shaft lines are rotatable in the same direction and for which the unbalance module of at least one of the lines is angularly adjustable, allows to generate circular vibrations whose amplitude is adjustable and with a reduced energy consumption. The angular modification device makes it possible to adjust the angular phase shift between the unbalance modules of the shaft lines, during the various operating sequences of the vibratory system. The angular adjustment of the unbalance module of at least one of the lines makes it possible in particular to reduce, or even to cancel, the static moment of all the unbalance modules for, at the start of the rotational training, 15 limit the energy required for said training, and for when stopping the rotational drive, limit the risk that the system generates frequencies close to the resonance frequencies of certain parts of the system or the corresponding machine.
    [0006] Thus, during a start-up sequence of the system, the angular modification device can be used to obtain a configuration of the unbalance modules of the opposite-phase shaft lines. When the vibratory system comprises two lines of shafts, a phase opposition configuration corresponds to a difference in angular position of 180 ° between the two unbalance modules. According to another example, when the vibratory system comprises three shaft lines each provided with an unbalance module, a phase opposition configuration corresponds to a difference in angular position of 120 ° between the unbalance modules of the first and second lines. , and at an angular position difference of 120 ° between the two unbalance modules of the second and third lines. The static moment of all the unbalance modules is then zero, which reduces the energy required for the rotational drive of the shaft lines.
    [0007] During an operating sequence, also called production mode, the angular modification device can be used to modify the angular configuration of the unbalance modules of the shaft lines in order to adapt the vibration level to the quality and quantity of materials to screen and / or advance. In order to shut down the system, the angular modification device may be used to bring the unbalance modules into phase opposition and thus limit the risk that all or part of the system or machine will resonate. According to an advantageous characteristic of the invention, the drive device comprises: a motor, called a main motor, configured to rotate one of the shaft lines; a synchronous transmission mechanism configured to transmit the rotation of the shaft line driven by the main motor to the other one or more shaft lines so that said shaft lines rotate synchronously and in a synchronous manner; the same way.

    [0009] According to an advantageous characteristic of the invention, the control unit is configured to, when the rotation of the shaft lines is stopped, bring the unbalance modules into the first angular configuration.

    [0011] The invention also relates to a method for controlling a vibratory system as described above, characterized in that said method comprises at least one step of modifying the angular position of an unbalance module with respect to the position angular position of the other or the other unbalance modules.

Referring to the figures and as recalled above, the invention relates to a vibrating machine 6 for screening and / or moving materials, such as aggregates or ores. Screening is an operation of sorting materials according to their particle size. The vibrating machine can thus be used for particle size grading or for the supply of materials in various fields such as public works, buildings, mines or quarries. The machine 6 comprises a frame 60 and a surface 62 for screening and / or movement of materials carried by said frame 60. Said surface may be made in the form of panels or plates, for example of rubber, or of a stretched fabric . For screening, said surface has voids and / or perforated meshes of dimensions adapted to the type of screening desired. The frame 60 of the machine 6 is disposed on damping means such as springs 61. The springs 61 then act as suspension and vibratory isolator. In other words, the machine comprises a frame 60 with elastic mounting. The machine 6 comprises a vibratory system 7 which makes it possible to generate vibrations. The vibratory system 7 is arranged to vibrate the surface 62.
    [0016] In particular, the vibratory system comprises support elements (not shown) which are fixed on the frame 60 of the machine 6. The support elements carry bearings 56 through which the shafts of the unbalanced shaft lines vibratory system 7 described below.
    [0017] In the example illustrated in the figures, the vibratory system 7 thus includes two unbalanced shaft lines 1, 2. In a variant, the vibratory system may comprise a larger number of shaft lines, for example three or four lines. 3033270 9 trees, equipped with unbalance modules. The shaft lines are parallel and preferably horizontal. Each unbalanced shaft line 1, 2 comprises a shaft, or several shafts integral in rotation with each other, and one or more unbalance modules 12, 21 mounted to rotate with the shaft (s). of the corresponding line. Said shaft may comprise several shaft portions interconnected for example by universal joints as is the case in the example illustrated in FIG. 4. Unbalanced means a body mounted on a shaft line and whose gravity center 10 is off-center with respect to the axis of rotation of said shaft line. In the example illustrated in the figures, each unbalance module comprises a plurality of imbalances. Alternatively, an unbalance module may consist of a single unbalance.
    [0018] In the example illustrated in the figures, each unbalance module 12, 21 comprises two pairs of imbalances. The two pairs of each unbalance module 12, 21 are spaced apart from each other along the shaft. The two pairs of each unbalance module 12, 21 are separated from each other by a cardan link 130, 230.
    [0019] The two unbalances of a pair are separated from each other along the shaft line by a shaft bearing 56 fixed via a support member (not shown) on the frame 60 of the machine 6. In the example of Figure 3, a single bearing 56 per shaft line has been shown.
    [0020] In the example illustrated in FIG. 1, the screening and / or displacement surface 62 is inclined and offset with respect to the plane passing through the axes of rotation of the unbalanced shaft lines.
    [0021] Said vibratory system 7 also comprises a motor 3, called the main motor, engaged with the first shaft line 1. According to a variant not illustrated in the figures, the shaft line engaged with the main motor 3 may be the second shaft line 2. Said system also comprises a synchronous transmission mechanism 30 configured so that the rotation of the shaft line 1 whose rotation drive is controlled by the main motor 3, is synchronous and in the same direction as the direction of rotation of the second shaft line 2. Thus, the first and second shafts rotate at the same speed of rotation relative to each other, and in phase or not, depending on the operating steps of the machine as detailed below. The synchronous transmission system 30 is thus configured so that the unbalanced shaft lines are rotated by the motor 3 at the same speed and in the same direction. This synchronous transmission system 30 comprises a wheel 31 fixed on the output shaft of the main motor 3, a shaft 134 mounted to rotate with the shaft line 1, a wheel 13 integral with the shaft 134 and a belt 100 transmission between the wheel 31 and the wheel 13. The synchronous transmission system 30 also comprises a wheel 14 attached to the shaft 134, and a wheel 45 coupled by a belt 101 to the wheel 14. The wheel 45 is carried by , but able to rotate relative to the output shaft 400 of the motor 41 adjustment. The transmission system also includes a ring gear 424 rotatably coupled to satellite gears 423 carried by the wheel 45 which forms a carrier. The shaft 134 and the ring gear 424 of the synchronous transmission system are respectively connected to the shaft lines 1, 2 by the cardan links 130, 230.
    [0022] Crown 424, planet gears 423 and planet carrier 45 are part of an epicyclic gear train 42 described hereinafter. The epicyclic gear comprises a sun gear 421 connected to the output shaft of a motor 41, called the adjustment motor, presented hereinafter. The epicyclic gear also includes an outer ring gear 424 connected to the second shaft line 2, and satellites 423 meshing with the ring gear 424 and the outer sun gear 421 424. The epicyclic gear train 42 also includes a gear wheel 423. satellite carrier 45 which carries the satellites 423 so that the rotation of the planet carrier 45 causes the satellites 423 to rotate. The vibratory system 7 comprises an angular modification device 45 configured to modify the angular position of the unbalance module 21 of the second shaft line 2 relative to the angular position of the unbalance module 12 of the first shaft line 1. According to a variant not illustrated in the figures, the angular modification device can be configured to modify the angular position of the unbalance module of the first shaft line or each of said shaft lines. More generally, when the vibratory system 7 comprises a number n of shaft lines provided with an unbalance module, with n greater than or equal to two, it can be provided that the angular modification device is configured to modify the angular position of n-1 rows of trees to be able to modify the static moment of all the 15 unbalance modules as detailed below. In the example illustrated in the figures, the angular modification device 4 comprises the epicyclic gear train 42 and the adjustment motor 41. The motor 41 has an output shaft 400 on which the sun gear 421 is mounted to rotate. Preferably, the adjustment motor 41 is a geared motor, that is to say a motor equipped with a gearbox, which allows the output shaft of the adjustment motor 41 to rotate at a reduced speed, compared with the motor rotation speed 4, and with high torque. As detailed below, the adjustment motor 41 and the epicyclic gear train 42 make it possible to modify the angular position of the unbalance module 21 of the shaft line 2 and thus to introduce an angular phase shift between the unbalance module 21 of the the second shaft line 2 and the unbalance module 12 of the first shaft line 1, or bring them in phase, that is to say in the same angular position.
    [0023] In the following, the orientation axis 012, 021 of an unbalance of a shaft line 1, 2 is defined as being the axis perpendicular to the axis of the shaft line which passes through the center of gravity of the unbalance and the axis of said shaft line.
    [0024] The angular phase shift between the unbalance modules, or the difference in angular position between the unbalance modules, corresponds to the difference between the angular position of an unbalance module and the angular position of the other unbalance module.
    [0025] The angular position of an unbalance module is defined as the angle Al2, A21, called the orientation angle, formed, in one direction, between a given reference axis which perpendicularly intersects the axis of rotation of said unbalance module. (That is, the axis of the corresponding shaft line) on the one hand, and the orientation axis 012, 021 of said unbalance module defined above, on the other hand. Said orientation angle is in a plane perpendicular to the axes of rotation of the shaft lines. In the example illustrated in FIG. 4C, which is a front view of the shaft lines, that is to say in a plane perpendicular to their axes of rotation, the reference axis for each unbalance module 12 , 21 is selected as the portion of the vertical axis V12, V21 which intersects the axis of rotation of said unbalance module and extends below said axis of rotation. In addition, in the example illustrated in FIG. 4C, said orientation angle is defined, in the counterclockwise direction, from the reference axis to the unbalance orientation axis. In other words, the angular phase shift between the unbalance modules 12, 21 corresponds to the difference between their orientation angles Al2, A21.
    [0026] In the example illustrated in the figures, for a given shaft line, the imbalances of the line have the same angular position from one imbalance to another, so that the angular orientation of an unbalance of a shaft line corresponds to the angular orientation of the unbalance module of said line. In the case where an unbalance module comprises imbalances angularly out of phase with each other, it can be considered that the angular position of the unbalance module corresponds to the average unbalance orientation angles of the unbalance module. The angular modification device 4 thus makes it possible to bring the unbalance modules 21, 12 into a first angular configuration, for example in phase opposition, for which the set of unbalance modules 10 has a first static moment value. The angular modification device 4 also makes it possible to bring the unbalance modules into a second angular configuration, for example in phase, for which the set of unbalance modules has a second static moment value lower than said first value.
    [0027] For setting the angular position of the unbalance module 21, the motor 41 operates at low speed and high torque. The motor 41 is configured so that the rotation of its output shaft 400 is irreversible so that, when the desired angular phase shift between the unbalance modules is reached, preventing a rotation of the sun gear 421 which inadvertently changes the angular orientation of the unbalance module 21 of the line 2. The vibratory system 7 comprises a control unit 700. The processing and calculation unit is an electronic and / or computer type unit, comprising for example a microcontroller or an associated microprocessor. to a memory. Advantageously, the vibratory system also comprises a system for detecting the angular position of the unbalance modules of the shaft lines. The detection system may comprise one or more sensors connected to the control unit for determining the angular phase shift between the unbalance modules of the shaft lines. The one or more sensors may be configured to detect the relative angular position between the unbalance modules or to determine the pivot angle of the or each shaft line controlled by the angular modification device 4. Thus in the example illustrated in the figures, the motor 41 may be equipped with a system for measuring the pivot angle of its output shaft to deduce the angular phase difference introduced between the unbalance modules of the shaft lines. Thus, when it is specified that the unit or means of the unit are configured to perform a given operation, it means that the unit comprises computer instructions and the corresponding execution means that make it possible to perform said operation. In particular, the control unit 700 comprises instructions for controlling the speed of rotation of the main motor 3 and the angle of rotation of the output shaft 400 of the motor 41.
    [0028] When the vibration system is stopped and to operate, the control unit 700 is configured to perform the following steps. Initially, the unbalance modules 12, 21 of the first and second shaft lines 1, 2 are stationary and at the same angular position, that is to say in phase, and preferably in the low position as illustrated in FIG. 4. In a first step illustrated in FIG. 4A, the angular position of the unbalance module 21 of the second shaft line 2 is modified using the motor 41 so that the unbalance module 21 is brought into an angular position, called the angular starting position, which is different from that of the unbalance module 12 of the first shaft line 1. Thus the static moment of the set of unbalance modules, called total static moment, in the starting position is less than that corresponding to a configuration of the unbalance modules in which they have the same angular position. The values of total static moment are here considered in absolute value. The energy required for the rotational drive of the unbalanced shaft lines by the motor 3 is then reduced.
    [0029] The static momentum of the set of unbalance modules 12, 21, called the total static moment, is defined with respect to an axis parallel to the axes of rotation of the lines, coplanar and equidistant from these two axes of rotation. 5 rotation. In the case of a number n, greater than two, parallel and coplanar tree lines, the static momentum of the set of unbalance modules, called total static moment, can be defined with respect to an axis parallel to the axes. rotation of lines, coplanar and equidistant from the two furthest lines of trees.
    [0030] Preferably, the unbalance modules 12, 21 are brought in phase opposition as illustrated in FIG. 4B. The total static moment is then zero. The control unit 700 then controls the rotation of the first and second 1, 2 shaft lines with the motor 3 so as to reach a given speed, called the nominal operating speed, as illustrated in FIG. 4C. During this step, that is until they reach the nominal operating speed, the unbalance modules of the shaft lines are kept in phase opposition.
    [0031] The control unit then controls the motor 41 to, as illustrated in FIG. 4D, modify the angular position of the unbalance module 21 of the second shaft line 2 so as to bring them into an angular position, called angular position. vibratory, for which the total static moment is greater than that corresponding to said starting angular position. Preferably, as illustrated in FIG. 4E, the unbalance module 21 is brought into the same angular position as that of the unbalance module 12. Thus, at the operating step illustrated in FIG. 4E, the vibratory system operates at the speed of nominal rotation and with a maximum vibration amplitude because the unbalance modules of the two lines are in phase. The control unit 700 can control the modification of the amplitude of the vibrations by modifying the angular position of the unbalance module 21 of the second shaft line 2 with respect to the angular position of the unbalance module 12 of the first tree line 1.
    [0032] The vibratory amplitude of the vibratory system can be reduced, as illustrated in FIG. 5, by introducing an angular phase shift between the unbalance modules. As explained above, the angular phase shift is introduced by driving the motor 41 so as to rotate the desired angle of the sun gear 421 of the epicyclic gear. The vibration amplitude can thus be progressively adjusted to a value between 0 and 100%. To control the stopping of the vibratory system, whereas, as illustrated in FIG. 6, the two shaft lines are rotated by the motor 3 at the nominal operating speed and in phase, the control unit executes the 15 following steps, corresponding to the inverse steps described above in connection with Figures 4 to 4E. According to the step illustrated in FIG. 6A, the motor 41 modifies the angular position of the unbalance module 21 of the second shaft line 2 until the angular positions of the unbalance modules 12, 21 of the first and second lines 1,2 are opposite (Figure 6B). Thus, the amplitude of the vibrations is minimal. Then, as illustrated in FIG. 6C, the rotational drive of the shaft lines 1, 2 is stopped so that the shaft lines stop rotating without the risk of bringing all or part of the machine into resonance. .
    [0033] Then, as illustrated in FIGS. 6D and 6E, the unbalance module is pivoted by the motor 41 to modify its angular position and, preferably, as illustrated in FIG. 6E, bring it into the same angular position as that of the module of FIG. In particular, the unbalance modules are brought into the low position, so that the potential energy of these unbalance modules 30 is zero, which makes it possible to intervene in a secure manner on the system, for example in the event of maintenance.
    [0034] The present invention can be advantageously used for the screening of materials in mines and quarries and / or the processing machine feed of said materials.
