Definitions

  • the invention relates to a weft thread storage device for a weaving machine, with a winding body for winding up the weft thread, which winding body consists of a drum-shaped part arranged eccentrically to the drive axis of the storage device and a plurality of brackets forming a radially adjustable winding part, which has a leg radially to the winding body the drum-shaped part are held, while the other leg, which runs essentially axially parallel to the storage axis, runs against a base plate of the winding body.
  • each radial leg of the bracket is held in a bore in the drum-shaped part by means of a clamping screw.
  • the axial leg runs directly against the base plate. If necessary, he can touch it without being attached to it.
  • the clamping screw must be loosened for each radial leg and the Push in the bracket more or less by hand and clamp it in a new position using the screw.
  • This adjustment of the bracket requires relatively great skill from the operator of the weaving machine. As a rule, the new position of the hanger which corresponds to the desired weaving width must be found out by trying.
  • the invention has for its object to provide a particularly improved device in this regard.
  • the invention consists in that the base plate is designed to be rotatable and is provided with at least one spiral groove, into which the axial limbs of the bracket project.
  • the adjustment of the stirrups as a fine adjustment for the weft insertion length, to which a corresponding rough adjustment belongs.
  • the coarse setting can be achieved, for example, by choosing a suitable number of turns on the winding former, which lead to the same weft insertion heard length.
  • the associated fine adjustment can be achieved by adjusting the bracket as described.
  • a schematically indicated drive shaft 2 of the storage device 3 is arranged in a cylindrical housing 1 and is driven via a toothed belt drive 4 according to arrow 5.
  • a thread feed tube 6 is attached, which is driven according to arrow 7.
  • the weft thread designated 8 is fed according to arrow 9 and wound in the form of windings 11 onto a winding body designated as a whole as 12.
  • a rod 51 is provided for mass balance with respect to the tube 6.
  • the winding body 12 consists of a drum-shaped winding part 19 arranged with its axis 18 eccentrically with respect to the axis 2 of the store 3 and, for example, seven stirrups 21 attached in the lower region of the part 19.
  • Each stirrup contains a leg 22 directed essentially radially to the part 19 and an axial leg 23 running essentially parallel to the axes 18, 2.
  • Each leg 22 projects into a recess 24 in the winding part 19, each leg 23 extends up to a base plate 26.
  • Disc 26 is rotatably supported on the winding part 19 with the interposition of a ball bearing 60.
  • Disc 26 has a curved slot 62 through which a clamping screw 61 is screwed into the winding part 19. After loosening the screw 61 /, the washer 26 can e.g. rotated by hand and clamped in a new position by means of screw 61.
  • the disk 26 contains a plurality of radially directed grooves 27 and a continuous, spiral-shaped groove 28.
  • the ends 29 of each axial leg 23 protrude into the spiral groove 28 and into an associated radial groove 27. Through ends 27, the ends 29 are guided during their radial movement.
  • the ends 31 of the radial legs 22 are clamped with the interposition of a rubber ring 32 by means of an end disk 33 using a clamping screw 34.
  • An angular guide part 41 is fastened to the housing 1 and has a slot 42 into which the teeth 40 of the separating disk 13 protrude. This will the winding body 3 consisting of the cylindrical part 19 and the brackets 23, which is rotatably mounted on the shaft 2, secured against rotation.
  • the arrangement is made, for example, in such a way that five turns 11a each enter one and the same tooth space 15a of the separating disk 13 and are axially transported therefrom in FIG. 1 to the right.
  • the five turns 11a can be pulled off overhead to the right.
  • the five turns Ila contain, for example, a length of 1.40 m, which is equal to the desired weaving width.
  • the screw 34 is loosened so that the stirrups 21 are loosened in the slots 24.
  • the screw 61 is then loosened and the disk 26 is rotated by hand in such a way that the brackets 21 are moved further outwards due to the spiral groove 28 in FIG. 2.
  • Each end 29 runs outward in the associated radial groove 27 by a corresponding amount, which can be read from the marks 44 of the legs 22.
  • the screws 61, 34 are tightened again, so that the washer 26 and the stirrups 21 are firmly seated again. Now the weaving operation can be continued with the new weaving width.
  • Further partial grooves 28, d, e are expedient mounted in the disc 26a as blind grooves so that the disc 26a can be used easily in any rotational position.
  • no temple ends 29 are guided in the grooves 28d, e.
