Definitions

  • the invention relates to a holding device for the rails, in particular contact rails of the warp thread monitor of a weaving machine, with a plate-shaped part encompassing the rails, which is arranged displaceably on a fixed support.
  • the plate-shaped part on the carrier is adjustable and fixable by means of an elongated hole and associated clamping screw. If the weaving machine has a large weaving width, several such carriers with displaceable, plate-shaped parts are needed in order to hold the rails of the warp thread monitor which extend over the entire weaving width. With the known adjusting device, it is difficult to bring about the same height position in the individual holders and plate-shaped parts, so that the rails of the warp thread monitor have exactly the same position over the entire weaving width and generally run horizontally. The drop height of the associated parking slats depends on the position of the contact rails of the warp thread monitor.
  • the invention consists in that an essentially wedge-shaped sliding element is connected between the plate-shaped part and the carrier and can be adjusted in stages along a slope located on the plate-shaped part and / or the carrier.
  • the weaving machine frame contains a rod 1 of oval cross-section running in the weft direction, to which several U-shaped holders 2 are fastened by means of screws 3 and clamping wedge 4. 1 and 2, a support 5 is inserted into each frame 2 from above. In its lower part it contains a sloping bar 5a, while in the upper part it consists of two parallel walls 5b.
  • a plate-shaped part 6, which has feet 7, is pushed between the walls 5b.
  • the lower end of the feet 7 in FIG. 1 lies on a straight line 10, which is indicated by dashed lines in FIG. 1.
  • the strip 5a has a toothing 8 in which teeth 9 engage, which are attached to the lower end of a sliding wedge 11.
  • the upper end 12 of the sliding wedge 11 forms a guide for the feet 7 arranged on the straight line.
  • the sliding wedge 11 has a nose 12 which projects between the two walls 5b.
  • the sliding wedge 11 is connected as a molded body in the gear connection (operative connection) between the carrier 5 and the plate-shaped part 6.
  • the wedge 11 When the wedge 11 is moved to the right in FIG. 1, it is expediently lifted out of the toothing 8 by inserting a tool into a bore 15 and pushed to the right according to arrow 16. He moves under the feet 7, so that the plate 6 is raised.
  • contact rails designated as a whole by 18, are guided in slots 17, while guide rails 19 are held in slots 21 of the carrier 5.
  • the contact rails 18 serve to shut down the weaving machine when a parking slat 22 falls as a result of breakage of a warp thread 23.
  • the guide rails 19 serve to keep the slats 22 lined up on the contact rail 18 at a distance from one another by holding the slat feet 24 between two guide rails 19 each .
  • the distance of the warp threads 23 above the rod 1 corresponding to the shed 51 is designated by A.
  • the wedge 11 After moving the wedge 11 in the frame of the opening 26 made in the carrier 5, the wedge 11 reaches e.g. 3, in which the plate 6 is positioned in the higher position 6a. This corresponds to the larger distance B of the warp threads 23 assumed in FIG. 3 with a larger shed 52.
  • the contact rails are in position 18a.
  • the fall time of a slat 22 in the event of a warp thread break is the same as in the position according to FIG. 1, since in both positions the fall height of the slats 22 has the same distance C between the contact rail 18 and the upper end of the associated slot of the slats 22.
  • the frame 2 consists, for example, of a metallic material, for example cast aluminum
  • the support 5 and the plate 6 are made of plastic, for example made of polyamide or polytetrafluoroethylene. Both the carrier 5 and the plate 6 are held at 31 in a guide of the frame 2. The parts in the drawing are pressed downward by the weight of the rails 18, 19, so that the teeth 9 are also constantly held in the toothing 8 and the wedge 11 cannot slide to the left.
  • the arrangement is such that both the wedge 11 on the bevel 29 or the toothing 8 and the plate 6 rest on the wedge 11 in a form-fitting manner. Clamping parts such as screws or the like are not required.
  • the arrangement is particularly easy to adjust and adapt to the prevailing conditions. With a modified design, e.g. the bevel 29 on the carrier 5 is omitted.
  • the toothing 8 then runs horizontally.
  • the slope formed by the feet 7 corresponding to the straight line 10 will then have a suitable, different slope.
  • the wedge 11 can be designed differently. At least one of the parts 5, 6 must be provided with an incline, by means of which the height of the plate 6 is adjusted when the sliding element 11 acting between the parts 5 and 6 is moved.
