Definitions

  • the invention relates to an adjusting device in the connection path between the swinging swing arm of a dobby and a shaft of a loom according to the preamble of claim 1.
  • the object of the invention is to improve the known adjusting device so that this vertical force is considerably reduced while maintaining the undisputed advantages of the known device, in particular the accessibility of the adjusting and clamping screws from the front side in the effective direction of the lever force.
  • the clamping means are advantageously formed by a U-shaped clamping bracket, which is arranged with respect to the tensioning means on the opposite side of the swing arm between a plate and two support points on the swing arm, and which during tensioning under the action of the tensioning means with the ends of its two legs pressed onto the surface of the adjustment plate in order to transfer the forces mentioned directly to the swing arm.
  • the clamping bracket is made of elastically deformable material and, when deformed, presses the ends of its two legs with frictional engagement onto the surface of the adjusting plate.
  • the play existing to facilitate assembly between the clamping bracket and the guide tube is first eliminated.
  • the swing arm between the U-shaped clamping bracket and the bracing means which are expediently formed, as is known, from a four-part wedge package from mutually supported spreading and clamping wedges, transmit the vertical force component present on the pivot bearing to the clamping bracket and from it via the frictional connection of the clamping bracket-swing arm without play.
  • lever drives 1 are articulated on the one hand with the shaft 2 of a weaving machine and on the other hand via a connecting rod 3, a rotary bearing 53 and the adjusting member 5 sliding on the swing arm 6 with a dobby machine, the swing arm 6 forming part of the dobby machine .
  • the indicated swivel angle of the swing arm 6 about its pivot point 4 results in the path A of the shaft necessary for weaving, that is to say the shaft stroke. If the shaft stroke A is to be increased, the setting member 5 must be moved in the direction B on the swing arm 6. To reduce the shaft stroke A, however, the adjusting member 5 is to be moved in the opposite direction C. Adjustment of the shaft must also be possible with regard to its basic position. This is achieved in that the rotary bearing 53 is displaced in the setting member 5 with respect to the swing arm 6 in the direction D or E.
  • the setting member 5 comprises a guide tube 50 with a transverse guide 60, in which the swing arm 6 is located.
  • the swing arm 6 is wrapped in a guide plate 7, the so-called loop, arranged in the tube 50.
  • the guide plate 7 is connected at one end to a plate 70 and at the other to a block 80.
  • a U-shaped clamping bracket 10 made of elastically deformable material is used, its purpose and Function will be explained in detail later.
  • the end of the tube 50 located on the right in FIG. 2 has a spindle guide plate 8, while on the other end of this tube, on the left in FIG. 2, the rotary bearing 53 is located for the articulation of the connecting rod 3 to the shaft.
  • the spindle guide plate 8 has a central bore through which an adjusting screw 72 is guided, which is screwed into a continuous threaded bore in the block 80 up to the stop on the expansion wedge 97.
  • the spindle guide plate 8 and the block 80 also have an eccentric threaded bore for receiving an adjusting screw 73, which is provided with a left-hand and a right-hand thread.
  • the adjusting screw 73 which is provided with a left-hand and right-hand thread, is actuated, the position of the tube 50 and the fulcrum 53 relative to the swing arm 6 can be changed in order to adjust the basic position of the shaft.
  • the adjusting member 5 on the swing arm 6 must be able to be moved up or down.
  • the Set screw 72 loosened, whereby the tension is loosened by the wedges 95, 96 and 97 and the displacement is made possible.
  • the wedges 95, 96, 97 are braced when the adjusting screw 72 is actuated via this three-point support, they are deformed in such a way that the two ends of its legs 11 and 12 move towards one another and are pressed onto the surface 100 of the adjusting plate 98 with frictional engagement.
  • the guide tube 50 and the guide plate 7 are clamped to one another and as a whole to the swing arm 6 to form a rigid unit in order to transmit the forces between the connecting rod 3 and the swing arm 6.
  • the shape of the recess 14 can influence the deformation in a desired way.
