Definitions

  • the invention relates to a training device for crowd for a loom.
  • the invention also relates to a loom equipped with such a device.
  • an eccentric is associated with at least one of the connecting rods, which allows transform a rotational movement of an electric motor in a movement of rising and falling of a frame.
  • an auxiliary clip must be provided on one of the connecting rods or one of the levers to allow a variation of the range of motion of a frame, that is, the adjusting the craft crowd.
  • the electric motor is animated by an oscillating rotary motion, this movement being transmitted to one of the control rods of a frame smooth without the use of an eccentric. It is possible to vary the amplitude of the crowd playing on the amplitude of the oscillating movement of the motor.
  • the known materials are bulky and the mounting a crowd training device is long and complex, especially as it requires the assembly of movement reduction devices and associated electric motors to transform the rotor movement of each motor in a movement whose speed and amplitude are consistent with the trajectory desired for heald frames.
  • the invention relates to a device for crowd training for a loom equipped with less a sleek frame that is operated by a system of drawing incorporating, for the or each frame, at least one connecting rod of a generated drive movement by an electric actuator with oscillating rotary motion.
  • the actuator includes a self-contained assembly incorporating an engine electric and a hollow-wheel gearbox, the output shaft the engine being equipped with a pinion engaged with a internal teeth of the hollow wheel, while this wheel hollow is able to drive in rotation, with a movement oscillations, a drive shaft of the connecting rod supra.
  • the actuator associated with each framework is a compact and be handled and installed autonomously, which facilitates the construction of a training device for crowd and maintenance operations of a loom equipped with such a device.
  • the invention also relates to a loom equipped with a crowd training device such as previously described. Such a job is more economical and easier to maintain than known trades.
  • the loom M shown in Figure 1 comprises a plurality of smooth frames, only one of which is shown in this figure with the reference C.
  • This frame C is equipped with rails 10 whose respective eyelets 11 are traversed by chain son 12 moving in the direction of the arrow F 1 .
  • the frame C is animated by a movement of vertical oscillations in the direction of the double arrow F 2 .
  • This movement is controlled by connecting rods, only one of which is visible in FIG. 1 with the reference 20, which are hitched in the lower part of the frame C as well as on two oscillating levers 22.
  • These levers 22 are interconnected by a connecting rod 24, while that one of the levers 22 is connected by a connecting rod 26 to a crankpin 28 mounted on a drive shaft 30 constituting the output member of an electric rotary actuator 40.
  • This actuator 40 is mounted on a support plate 80.
  • the plate In practice, and as shown in phantom Figures 1 and 2, the plate is provided wide enough to allow him to support one or more others actuators 40 'of the type of the actuator 40.
  • the number of actuators 40 is adapted according to the number of frames C to train.
  • the actuator 40 is provided with two orifices, only one of which is visible in FIG. 2 with the reference 41, which are aligned with orifices 81 provided on the plate 80, which allows the passage of fixing screws, of which only one is visible with the reference 43, the second being identified by its axis X 43 .
  • Nuts 43a are provided for immobilizing the screws 43 and the like in the orifices 41 and 81.
  • the actuator 40 comprises an elongate body 42 according to a direction A-A 'corresponding to an axis of rotation of a rotor 44 belonging to an electric motor 46.
  • the rotor 44 forms the output shaft of the motor 46.
  • stator 48 of the motor 46 the stator being arranged radially around the main part of the rotor 44.
  • the rotor 44 is supported relative to the body 42 through bearings 44 a and 44 b.
  • the rotor Relative to the middle part of the rotor 44 located between the bearings, the rotor extends to the level a brake system 50 electrically controlled and known in itself.
  • the rotor 44 is integral with a gear 52.
  • the pinion 52 may be attached to the rotor 44.
  • This pinion 52 is provided with an external toothing 52 is adapted to cooperate with an internal toothing 54 has a hollow wheel 54 which is integral with the drive shaft 30.
  • the teeth 54 a is formed on the inner radial surface of a sector 54 b fixed to the main part 54 c of the wheel 54 by means of screws, of which only one is visible in Figure 3, with reference number 55.
  • the hollow wheel 54 could be attached to the shaft 30 and assembled thereto by any suitable means.
  • the sector 54 b could be monobloc with the main part 54 c .
  • Bearings 30a and 30b support the shaft 30 and the ring gear 54 relative to the remainder of the actuator 40.
  • the elements 52 and 54 are disposed inside a housing 56 closed by a cover 58, so that it is formed, between the bearing 44 b and the cover 58, a closed volume V 56 in which is retained trapped a lubricant, such as oil, and in which the elements 52 and 54 constitute a reduction gear 60 of the oscillating rotary movement of the rotor 44, which makes it possible to control the oscillating rotary motion of the shaft 30 and thereby , that of the rocking levers 22 and the oscillating movement of the frame C in the direction of the double arrow F 2 .
  • the oscillating rotary movement F 3 of the rotor 44 is transmitted, thanks to the members 52 and 54, to the shaft 30 which is thus driven by a movement of the same nature F 4 .
  • This movement is transmitted by the crankpin 28 to the rod 26 which has a movement F 5 itself transmitted by the levers 22 and the rods 20 and 26 to the frame C which has the movement F 2 .
  • the amplitude and the speed of the movement F 2 are easily adjustable by varying the amplitude and the speed of the movement F 3 .
  • the actuator 40 is provided at this face 40a, a connector 72 intended to allow the connection of the actuator 40 on a connector 82 of form corresponding carried by the plate 80 and connected to a line 82a power supply of the actuator 40.
  • the connector 82 is provided on the face 80a of the plate 80 against which bears the face 40a when the actuator is mounted on the board.
  • the actuator 40 is equipped with a second connector 74 intended to be connected to a connector 84 corresponding shape, also provided on the face 80a of the plate 80.
  • the connector 84 is connected by a line 84a to unrepresented means of control / command of the actuator 40.
  • the connectors 72 and 74 are sufficiently distant from each other to avoid any risk of disturbance.
  • the connectors 72 and 74 could be grouped as a single connector, some wires drivers being then shielded to avoid disruptions.
  • the plate 80 is provided with a passage orifice 85 of the end of the shaft 30 on which is mounted the crankpin 28.
  • Two orifices 76 and 78 formed on the face 40a are intended to cooperate with male connecting members 86, respectively 88, provided on the face 80a of the plate 80 to allow circulation to the inside of the body 42 of a coolant coolant motor 46.
  • a fluid circulation circuit 46a coolant is provided in the housing 42, especially between the stator 48 and the body 42.
  • the arrows F 6 and F 7 represent the direction of circulation of the coolant.
  • the number of actuators can be easily and quickly adapted to the number of frames to train. Of even, the maintenance operations are facilitated, in particular the standard exchange of one or more actuators.
