Definitions

  • the invention relates to a device for driving the boom of a movable barrier in rotation around an axis perpendicular to this boom, and between two extreme positions, one of which corresponds to the closure of a passage and the other corresponds to the opening of this passage.
  • an electric motor is generally used, the angular stroke of rotation of which can be less than one revolution, the output shaft of which can remain stationary while the motor is under tension without the latter being damaged, and which can operate in both directions of rotation at will.
  • a motor is known in itself and generally consists of a lockable single-phase motor with constant torque, commonly designated by the expression "torque-motor”.
  • the drive device generally comprises a driven shaft mounted on a frame so as to be able to pivot around the horizontal axis perpendicular to the heald, the heald being driven by one of its ends in rotation by this driven shaft which is itself driven in rotation by a driven rod pivoting about the same horizontal axis.
  • the output shaft of the electric motor is coupled to a connecting rod-crank system, and the crank has its free end connected to the free end of the driven connecting rod.
  • the motor drives the connecting rod of the connecting rod-crank system in rotation substantially through a half-turn between two elastic stops which limit the trajectory of this connecting rod.
  • the rail of such a movable barrier must, for safety reasons, be able to be locked in a horizontal position. It is generally necessary to prevent a user from being able to manually raise the boom.
  • the resistance of the motor alone is generally insufficient in this regard.
  • the connecting rod-crank system when the heald is in a horizontal position, the connecting rod-crank system is arranged so as to be at one of its top or bottom dead centers, thereby effecting mechanical locking of the heald in horizontal position. .
  • it turns out that with such devices it is difficult in practice to obtain a blocking of the arm in the vertical position, in particular taking into account the problems of space and the other constraints imposed elsewhere. Therefore, in a strong horizontal wind, the barrier of the barrier in the vertical position can be inadvertently brought back to its horizontal position and thus hinder the free passage of people or vehicles.
  • the elastic stops limiting the rotational stroke of the rod driven by the engine generate phenomena of vibration in the extreme positions of the heddle. These phenomena are obviously undesirable and in particular cause very rapid wear of the shaft mounting bearings and mechanical connections.
  • the invention aims to remedy simultaneously the aforementioned drawbacks of the drive devices of the prior art.
  • the object of the invention is therefore to propose a drive device which is simple to adjust, much faster, in particular allowing a passage of the beam between its two positions. extremes in less than 1 s-, incorporating a minimum number of parts, and which does not include an elastic end-of-travel stop generating untimely vibrations. More particularly, an object of the invention is to provide such a device in which the speeds and the resisting torque tend to be zero in the extreme positions, by geometric construction.
  • Another object of the invention is to provide such a drive device which can not only block the boom in an extreme position, in particular horizontal, but also block the boom in the other extreme position, in particular vertical , and this in a simple and economical way.
  • Another object of the invention is to provide such a drive device in which the electric motor operates with a rotation stroke of its motor shaft less than 120 °, in particular of the order of 90 °.

  • the orientation of the driving rod - defined by the direction passing through the axis of rotation of this driving rod and by the axis of the pivot connection -, and the orientation of the driven rod - defined by the direction passing through the axis of rotation of this driven connecting rod and by the axis of the pivot link, are generally perpendicular to each other in at least one of the two extreme positions of the heddle. In this position where the orientations of the connecting rods are perpendicular to each other, mechanical locking is achieved, since the driven connecting rod cannot rotate the driving connecting rod.

  • the means of association of the two driving rods and led to one another consist of a roller mounted free in rotation at the free end of the driving rod around a shaft parallel to the 'motor shaft and the driven shaft, and a radial groove of the driven rod in which the roller is engaged so as to cooperate by contact with the bearing surfaces of the groove.
  • These radial bearing surfaces of the groove allow the roller making the pivot connection to slide radially relative to the rod connected to the driven shaft.
  • the motor shaft extends under and vertically from the driven shaft, and the driving rod is in the form of a flywheel portion whose center of gravity is eccentric relative to the motor shaft and to the orientation of this driving rod, so as to form a return counterweight tending to drive this driving rod in rotation in one direction - in particular in the direction corresponding to the return or to the maintenance of the arm in the vertical position - in the absence of electrical power to the motor.
  • a return spring drives the driven shaft to assist this motor in the rise of the arm and to return the arm to the vertical position in the event of the power supply to the motor being cut off.
  • the invention also relates to a drive device incorporating the above characteristics, in combination, and more particularly suitable for driving a heald about a horizontal axis.
  • the invention solves the problem mentioned above.
  • the driving and driven connecting rods are perpendicular to each other, that is to say when the groove is perpendicular to the orientation of the driving connecting rod, the engine-resisting torque is , due to the geometry of the mechanism, which is extremely low or even zero when the engine is started. Therefore, the engine can, at startup, have a significant acceleration, acceleration which allows it to quickly take a speed of significant value.

  • An electric motor 7 rotates the driven connecting rod 6, the driven shaft 3, and the heddle 1.
  • This motor 7 is capable of being able to be stopped by force under tension without undergoing deterioration such as a burnout of its windings.
  • the electric motor 7 is chosen and controlled by an appropriate device so that it can rotate in one or the other direction of rotation depending on whether the heddle 1 must be raised from the horizontal position to the vertical position or lowered from the vertical position to the horizontal position.
  • Such a control device of such an electric motor is known in itself and therefore does not have to be described or shown.
  • the shaft 8 of the engine is arranged to extend parallel to the driven shaft 3.
  • the shaft 8 of the engine is connected to the driven connecting rod 6 by means of a driving connecting rod 9 driven in rotation by the shaft 8 of the motor, the two driving connecting rods 9 and driven 6 being associated with each other by means 10, 13 of association producing a connection of the pivot link type with axis 11 of parallel pivoting to the shaft 8 of the motor and to the driven shaft 3.
  • the pivot connection of the means 10, 13 of association is also capable of sliding in translation radially with respect to the driven connecting rod 6 and to the driven shaft 3 , that is to say perpendicular to its axis 11.
  • the means 10, 13 of association form a connection between the two connecting rods, 6, 9 with two degrees of freedom: a rotation around the axis 11 of the pivot connection, and a translation perpendicular to this axis 11 and in the stiff direction of the driven shaft 3.
  • the pivot link slides in translation along the driven rod 6 radially while driving this driven rod 6 in rotation around the driven shaft 3.
  • the axis of rotation of the driving rod 9 is parallel or coincident with the horizontal axis of rotation 14 of the shaft 8 of the engine.
  • the direction D2 passing through the axis of rotation of this driving rod 9 and through the axis 11 of the pivot connection of the means 10, 13 of association defines the orientation overall of the driving connecting rod 9.
  • the direction D1 passing through the axis of rotation of the driven connecting rod 6 and through the axis 11 of the pivot link of the association means 10, 13 defines the overall orientation of the driven rod 6.
  • these two orientations D1, D2 are generally perpendicular to one another in at least one of the extreme positions of the heald 1 -in particular at least in the horizontal position of the heald 1- .
  • these orientations D1, D2 of the connecting rods 6, 9 are perpendicular to each other in the two extreme positions of the heddle 1, that is to say in horizontal position and in vertical position.
  • the driven rod 6 cannot drive the driving rod 9 in untimely rotation.
  • the action of the driven rod 6 on the driving rod 9 can only be done on the pivot link by reaction of the means allowing the radial translation of this pivot link.
  • this reaction is perpendicular to the direction of translation, that is to say perpendicular to the driven connecting rod 6.
  • Reducing devices could be provided between the different elements of the connecting rod mechanism driven by each other. Thanks to such reducers, one could for example use rods driven 6 and driving 9 of different lengths and angular strokes.
  • the driven connecting rod 6 and the heddle 1 are mounted directly on the driven shaft 3 integral in rotation with the driven shaft 3 by means 15, 16 coupling.
  • the coupling 15 of the connecting rod driven on the shaft 3 can be a coupling by tightening, by geared tightening, or by crimping or the like.
  • the coupling 16 of the end 5 of the heddle 1 on the shaft 3 is located at a free end 17 of the shaft 3 opening out of the frame 4.
  • the driven shaft 3 is mounted on the frame 4 thanks to bearings or bearings 18, 19 one of which 18 supports one end 20 of the shaft 3 and the other of which 19 allows the free end 17 of the shaft 3 to exit outside the frame 4.
  • the coupling 16 of the heald 1 on the free end 17 can be made in any suitable manner, for example by means of a set of flanges 21 in the form of a band encircling the end 5 of the heald 1 and clamped to a plate 22 by means of screws or suitable tensioners, the plate 22 being mounted integral in rotation with the driven shaft 3 and extending perpendicular to the horizontal axis 2 of rotation of this shaft 3.
  • the driving rod 9 is mounted directly on the motor output shaft 8, integral in rotation with the motor shaft 8 by means of a rigid coupling 23 which can be produced by tightening, mesh tightening, crimping or the like ... If the motor 7 includes a reduction device which is incorporated therein, the driving rod 9 is then mounted directly on the output shaft of said reduction gear which is considered to be the output shaft of the motor.
  • the orientations D1, D2 of the two driving and driven connecting rods 6, 9 being generally at right angles to one another in these extreme positions of the arm 1, the stroke of the shaft 8 of the engine being 90 ° between these two extreme positions.
  • the drive device according to the invention is particularly simple, incorporates few parts, is reliable, easy to adjust, extremely fast, and optimizes the operating conditions of the electric motor 7.
  • the two connecting rods being at an angle right in each of the extreme positions, the torque resisting starting the engine is zero or almost zero.
  • blocking of the heddle 1 is carried out in the two extreme vertical and horizontal positions.
  • the means 10, 13 for associating the two connecting rods 6, 9 between them consist on the one hand of a roller 10 mounted free in rotation at the free end 24 of the driving rod 9 around a horizontal shaft 12 mounted fixed relative to the driving rod 9 parallel to the motor shaft 8 and to the driven shaft 3, and on the other hand to a radial groove 13 of the driven connecting rod 3 in which the roller 10 is engaged, the radial groove 13 forming bearing surfaces for the roller 10 which cooperates by contact with radial surfaces 25, 26 facing the groove 13.
  • the radial bearing surfaces 25, 26 of the groove 13 are placed parallel to each other, on either side and at equal distance from the radial direction of the axis 2 of the driven shaft 3, that is to say of the orientation D1 of the driven connecting rod 6.
  • the distance between the radial bearing surfaces 25, 26 corresponds, apart from the clearance allowing the rolling of the roller 10, to the external diameter of the roller 10. From the so, for any angular position of the driving rod 9, corresponds, apart from play, one and only one angular position of the driven rod 6, that is to say of the arm 1.
  • the groove 13 is closed at each of its ends, and, according to the invention, at the free end 27 of the driven rod 6 by cylindrical portions of revolution with horizontal axis 28, 29.
  • the cylindrical portions 28, 29 connect the radial bearings 25, 26 continuously at each end of the groove 13. In each extreme position of the heddle 1, the roller 10 comes into contact with the cylindrical portion 28 located at the free end 27 of the driven connecting rod 6.
  • This portion cylindrical 28 is therefore placed at such a distance from the axis 2 of the driven shaft 3 that when the roller 10 comes into contact it is equidistant from the axis 2 of the driven shaft 3 and the axis 14 of the shaft 8 of the engine, the orientations D1 and D2 of the two connecting rods 6, 9 being perpendicular to one another ( Figures 1, 2, 4 and 5).
  • the other cylindrical end portion 29 is located on the internal side close to the driven shaft 3 at a distance sufficient to allow the passage of the two connecting rods 6, 9 in alignment with each other midway between the two extreme positions and between the shafts 3, 8, that is to say when the heald 1 is at 45 ° relative to the horizontal. It should be noted that the other variant in which the groove extends towards the free end of the connecting rod 6 from internal cylindrical portions in the extreme positions, the driving rod 9 rotating under the shaft 8, would be feasible.
  • the shaft 8 of the motor extends under and vertically from the driven shaft 3.
  • This length L1, L2 is determined according to the gear ratio that we want to give to the device d 'drive, taking into account the characteristics of the motor 7 in particular.
  • the motor 7 is placed on a support 30 rigidly associated with the frame 4 by any appropriate means (welding, bolt, etc.).
  • the drive device comprises means making it possible to place the heald 1 in a vertical position and to maintain it in this position in the event of the power supply to the motor being cut off. Indeed, if the motor 7 is no longer supplied with electricity, safety standards require that the arm 1 automatically returns to the vertical position. In addition, it is desirable that the heald 1 remains in this vertical position. To do this, one can provide a return spring acting directly on the driving rod 9 or on the shaft 8 of the engine. However, such a spring would be difficult to assemble, adjust and maintain. This is why, the drive device according to the invention comprises a return spring 31 driving the driven shaft 3 to bring the heald 1 back to the vertical position in the event of the power supply to the motor being cut off.
  • the connecting rod 33 is angularly oriented relative to the driven shaft 3 and the driven connecting rod 6 to tension the spring 31 in the horizontal position of the arm 1 ( Figure 2) and return this arm 1 in position vertical ( Figure 1).
  • the spring 31 also has the function of compensating for the torque due to the weight of the stringer 1 on the rise by assisting the motor 7.
  • the driving rod 9 is a simple rod.
  • Figure 2 we can see ( Figure 2) that in the horizontal position of the arm 1, if the motor supply comes to be cut, the action 31 of the spring has no effect since, as has been explained, the driven connecting rod 6 cannot rotate the driving connecting rod 9, the groove 13 extending perpendicular to the direction D2 of the driving rod 9. It suffices for a slight movement of the roller 10 in the groove 13 towards the internal cylindrical portion 29 to get out of this blocking point and allow the effective lifting of the arm 1 under the effect of the spring 31.
  • the driving rod 9 is provided with a counterweight which can be of low value taking into account that the displacement of the roller 10 in the groove 13 from the extreme horizontal position of the heddle 1 requires little effort, thanks to the geometry of the mechanism.
  • This counterweight can be simply achieved by an extension of the driving rod 9 opposite or generally opposite with respect to the shaft 8 of the engine, or even by another connecting rod mounted integral with this shaft 8 of the engine in a appropriate direction, extension or other connecting rod to which a mass of determined value could be suspended.
  • the torque that this counterweight must exert must simply overcome the resistive torque of the motor not supplied with current increased by the torques due to friction in the extreme horizontal position.
  • the driving rod 9 is in the form of a flywheel whose center of gravity is eccentric relative to the shaft 8 of the engine and to the 'orientation D2 of this driving rod 9, so as to form a return counterweight tending to drive this driving rod 9 in rotation in one direction in the absence of electrical power to the motor.
  • the driving rod 9 consists of an angular sector of the disc extending generally on one side of the direction D2.
  • the angle formed by this sector is between 90 ° and 180 °, in particular is of the order of 120 °.
  • One of the sides of this angular sector of the flywheel portion is formed by the orientation D2 of the driving rod 9, that is to say by the direction passing through the axis 12 of the roller 10 and through the axis 14 of the motor shaft 8. This side is simply slightly extended beyond the direction D2 to allow the mounting of the driving rod 9 on the shaft 8 thanks to the coupling 23.
  • the engine torque supplied to the driven shaft 3 is maximum in the vicinity of the aligned position of the orientations D1 and D2 of the two driven and driving connecting rods corresponding to the position of the beam at 45 °. In this position, the boom rotation speed is also at its maximum.
  • the axis 2 of rotation of the barrier is perpendicular to the heald 1.
  • the heddle 1 pivots horizontally along an axis 2 disposed vertically.
  • the means 10, 13 of association can comprise an elastic stop system.
  • the cylindrical part 28 of the groove 13 is equipped with an elastic stop 280, 281.
  • This stop is such that in the closed closed end position, the motor being supplied, the roller 10 exerts a slight compression force f1 on the stop, to stress the latter.
  • the removal of the force f1 causes the release of the stress and the release of the stop which decompresses by causing the displacement along F2 of the roller 10.
  • This displacement has the effect of facilitating lifting of the barrier in the event of a power failure, the movement then being initiated and continued thanks to the shape of the driving rod 9 as has already been explained previously.
  • FIG. 11 shows a variant according to which the return spring is a compression spring whereas in the previous embodiments, the device was equipped with a tension spring.
  • a rod 310 connected to the free end 32 of the connecting rod 33, comprises at its lower end a stop 311 constituted by a nut 312.
  • the compression spring 313 being on the one hand bearing against this lower stop 311 and on the other hand, bearing on an upper stop 314 constituted by the support 30 of the motor 7.
