Definitions

  • the invention relates to a warp let-off control device for weaving machines with at least two partial warp beams, with a stationary rod-shaped deflecting element for the chain, which is connected downstream of the warp beams in the warp running direction, and a tensioning boom, which is connected downstream and movable under spring action.
  • the warp let-off speed i.e. the speed of the warp beam
  • the warp let-off speed is controlled by pressing the tensioning arm downwards counterclockwise, for example when the speed of the warp beam is too low, and thus the warp beam brake via a lever arm relieved, so that the warp beam can run faster under the increased warp tension.
  • a feeler roller is attached between the deflection beam and the warp beam, which is acted upon by the warp threads and changes its position as the warp beam diameter decreases, since the warp sheet in contact with it follows the circumference of the warp beam.
  • the feeler roller is connected to the above-mentioned lever via a linkage and, with a decreasing warp beam diameter, acts on the warp beam brake in a similar way to the tensioning beam with increasing warp tension.
  • the invention has for its object to provide a warp let-off control device which allows a single continuous spanning beam even when weaving several sub-warp beams and in which those elements which have to be arranged several times for each individual warp beam are designed as simply as possible.
  • This object is achieved according to the invention in that for the individual adjustment of the warp let-off speed of a part chain, depending on the thread tension in this part chain, a part warp beam is assigned to a control element arranged between the deflection element and the tensioning tree, by means of which the tension of the respective part chain is sensed.
  • Two partial warp beams 3, 4, which have partial weaving widths A, B, are arranged between the two machine cheeks 1, 2.
  • the partial warp beam 3 is driven by an electric motor 5, the partial warp beam 4 by an electric motor 6 each via a gear drive 7.
  • the overall weaving width of the machine is labeled C.
  • the two warp beams 3, 4 are supported on the inside by an intermediate support 12.
  • the weaving chains 8, 9 are guided over a fixed, arranged in the machine frame, the warp beams 3, 4 - in the warp running direction 11 - downstream, non-rotatable deflection roller 13 and a spreader beam 14 connected thereafter, whereupon they pass through the other parts of the weaving machine such as heald frames, reeds, etc. be directed.
  • the parts 13, 14 extend over the entire width C of the weaving machine.
  • a number, for. B. a hundred warp threads 15 guided over a feeler roller 16.
  • a number of warp threads 17 of the chain 9 are passed over a feeler roller 18.
  • Each roller 16, 18 is attached to a leaf spring 20, which is attached at 19 in a shoe 21.
  • the shoe 21 is fastened on the deflection roller 13 by means of a screw connection 22.
  • the shoe 21 also carries a sensor 23, which is connected via an electrical line 24 to a partial control device 25 assigned to the partial warp beam 3.
  • the feeler roller 18 is fastened on the deflection roller 13 and a control line 26 is guided to a part control device 27 assigned to the part warp beam 4.
  • the drive motors 5, 6 of the two warp beams 3, 4 are controlled by the control devices 25, 27 via lines 28 and 29, respectively.
  • the tensioning tree 14 is seated on a pivot lever 31, which is only indicated in FIG. 2 and which has a torsion spring bar 33 arranged at one end thereof in a fixed supporting tree tube 32 is bound.
  • the torsion spring rod 33 is connected at its other end to the machine frame 1, 2 (cf. CH-PS 631 756; EP patent application 82 / 810448.9).
  • the tension of the chains 8.9 is absorbed by the spring rod 33 twisted at one end.
  • the spanning tree 14 can e.g. B. can be adjusted by appropriate preloading of the torsion spring rod 33 so that it is in the position shown in FIG.
  • the warp threads of the chain 8 of the partial warp beam 3 run directly from the deflection roller 13 to the tensioning beam 14.
  • the warp threads 15 run at a certain angle over the feeler roller 16.
  • the two chain tension forces of the same size are designated E, F. From them, the resulting sensing force G directed toward the sensor 23 arises. B. about 20% of the amount of the voltage verifiers E, F.
  • the force relationships on the feeler roller 18 correspond to those on the feeler roller 16, as shown in FIG.
  • a correspondingly reversed signal is now sent to the part control device 27 via the feeler roller 18, whereby the warp let-off speed on the part warp beam 4 is immediately reduced.
  • the desired chain tension of the same size is therefore created again in the shortest possible time.
  • the device can also, for. B. can be used in looms with three warp beams. Then three tracer rollers are required, one on each part of the warp beam.
  • the spanning tree 14 can also under the action of two laterally arranged coil springs z. B. stand according to DE-PS 1 138 715.
