Definitions

  • the invention relates to a projectile brake for weaving machines, with a movable and a fixed brake shoe, and an actuator for controlling the braking action by means of an adjusting spindle driven by the actuator.
  • the invention has for its object to provide a projectile brake of the type defined, which does not have the disadvantages mentioned above. According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.
  • the subclaims relate to advantageous further developments.
  • a projectile brake 1 has an upper, movable brake shoe 2 and a lower, fixed brake shoe 3. Both brake shoes are provided with a brake pad 4 or 5.
  • the upper brake shoe 2 can be moved up and down in a guide 6.
  • the upper brake shoe 2 is connected via a lever system 8 to a slider 9 which can be moved up and down in a guide 10.
  • the slider 9 is guided with an oblique end face 9 'under the pressure of a spring, not shown, on a corresponding oblique side 11' of an actuator in the form of an adjusting wedge 11.
  • An opposite side 11 "of the setting wedge 11 is guided on the weaving machine 12.
  • the setting wedge 11 is provided with a threaded bore 13, in which a threaded adjusting spindle 14 of a servomotor 15 is screwed.
  • the lever system 8 consists of two levers 20 and 21, which are in one Joint 22 are connected to each other and to a brake lever 23 operated by the machine for closing and opening the projectile brake 1.
  • the extent of the braking effect of the projectile brake 1 is detected by means of two sensors 25 and 26 and a control device 27.
  • the sensors 25 and 26 are attached along the braking distance of a projectile 28 and are connected to the control device 27 via a line 29 and 30, respectively.
  • the output of the control device 27 is connected to the servomotor 15 via lines 31 and 32.
  • the control device 27 forms a corresponding actuating signal for the servomotor 15 in order to adjust the adjusting wedge 11.
  • the adjusting wedge 11 will be removed Motor 15 pressed to the left, so that the upper brake shoe 2 is slightly raised under the spring pressure, which is equivalent to a less strong braking effect when the brake is closed by the brake lever 23. If the projectile 28 penetrates too deeply into the brake, which means that the braking effect is insufficient, the servomotor 15 pulls the adjusting wedge 11 to the right, so that it moves the brake shoe 2 somewhat downwards, which results in a stronger braking effect. If the braking effect is correct, the control device does not form a control signal for the servomotor.
  • a right end face 35 'of a slide 35 is guided on a right side 36' of an adjusting wedge 36.
  • the adjusting wedge 36 is in turn guided with an opposite inclined surface 36 "on an inclined surface 37 of the weaving machine 38.
  • the mode of operation of the device is similar to that described for Fig. 1.
  • the advantage of this arrangement is that only axial positioning forces are applied to the slide 35 Effect come so that the friction in the guide 39 of the slider is only low and vibrations of the brake shoe 2 are avoided.
  • the adjusting wedges 11 and 36 are preferably made of a plain bearing material so that the required actuating force is small.
