Definitions

  • the invention relates to a shedding device 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 makes it possible to transform a rotational movement of an electric motor into a movement of upward and downward movement 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 amplitude of the movement of a frame, that is to say the adjustment of the crowd of the job.
  • the invention more particularly relates.
  • the known materials are cumbersome and the assembly of a device for forming the crowd is long and complex, especially insofar as it requires the assembly of movement reduction devices and electric motors. associated to transform the rotor movement of each motor into a movement whose speed and amplitude are compatible with the desired path for the heald frames.
  • the invention relates to a shedding device for a loom equipped with a at least one stringer frame which is actuated by a pulling system incorporating, for the or each frame, at least one transmission rod of a driving movement generated by an oscillating rotary electric actuator.
  • the actuator comprises an autonomous assembly incorporating an electric motor and a hollow-wheel gear, the output shaft of the motor being equipped with a pinion meshing with an internal toothing of the hollow wheel, while that this hollow wheel is adapted to drive in rotation, with a movement of oscillations, a drive shaft of the aforementioned rod.
  • the actuator associated with each heald frame is a compact and can be handled and installed independently, which facilitates the construction of a crowd forming device and maintenance operations of a loom equipped with such a device.
  • the invention also relates to a loom equipped with a shedding device as previously described. Such a craft is more economical and easier to maintain than known trades.
  • the loom M represented at figure 1 comprises several frames of smooth, of which only one is shown in this figure with the reference C.
  • This frame C is equipped with rails 10 whose respective eyelets 11 are traversed by warp 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 at figure 1 with the reference 20 which are hitched in the lower part of the frame C and two oscillating levers 22.
  • These levers 22 are interconnected by a connecting rod 24, while one of the levers 22 is connected by a connecting rod 26 to a crank pin 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 with the figures 1 and 2 , the plate is provided wide enough to allow it to support one or more other actuators 40 'of the type of the actuator 40.
  • the number of actuators 40 is adapted according to the number of C frames to be driven.
  • the actuator 40 is provided with two orifices, only one of which is visible at the figure 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 X axis line 43 .
  • Nuts 43a are provided for immobilize the screws 43 and equivalents in the orifices 41 and 81.
  • the actuator 40 comprises a body 42 elongate in a direction AA '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.
  • the motor stator 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 With respect to the middle portion of the rotor 44 located between the bearings, the rotor extends to the level of a brake system 50 electrically controlled and known per se.
  • 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 the figure 3 , with the reference 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 within a housing 56 closed by a cover 58, so that it is formed between the bearing 44b and the cover 58, an enclosed volume 56 wherein V is selected 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 with a connector 72 intended to allow the connection of the actuator 40 to a connector 82 of corresponding shape carried by the plate 80 and connected to a supply line 82a. electrical current 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 plate.
  • the actuator 40 is equipped with a second connector 74 intended to be connected to a connector 84 of corresponding shape, also provided on the face 80a of the plate 80.
  • the connector 84 is connected by a line 84a to unrepresented means for controlling / controlling 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 together as a single connector, some of the conducting wires being then shielded to avoid disturbances.
  • the plate 80 is provided with an orifice 85 for the passage of the end of the shaft 30 on which the crankpin 28 is mounted.
  • a coolant circulation circuit 46a is provided in the housing 42, in particular between the stator 48 and the body 42.
  • the number of actuators can be easily and quickly adapted to the number of frames to train. Similarly, the maintenance operations are facilitated, including the standard exchange of one or more actuators.
