Definitions

  • the invention relates to a warp let-off control device for weaving machines, in particular with two or more partial warp beams, with a stationary, rod-shaped deflecting element for the chain connected downstream of the warp beam in the warp running direction and a tensioning beam which is connected downstream and movable under spring action.
  • the warp let-off speed is controlled by the tension or position of the chain being sensed by the movable tensioning arm itself. According to the position of the spanning tree is a corresponding sensor a signal to do given Steuereinrich- g. From this the warp beam drive receives a corresponding signal, which adjusts the warp let-down speed.
  • the reaction speed of this known warp let-off control device is limited in that the entire spanning boom must follow the warp tension changes and a certain time is required for this; the warp let-off speed can therefore only be adjusted after this time has elapsed.
  • the invention has for its object to provide a control device which is particularly improved in this regard.
  • the invention relates to a probe (16) of the control device (16, 23, 25) being arranged on the chain (8) between the deflection element (13) and the tensioning tree (14), by means of which the tension or the respective deflection element ( 13) and tensioning tree (14) leading path of the warp threads (8) are scanned and the warp let-off speed is set accordingly.
  • the warp beam contains a plurality of sub-beams, each sub-warp beam being assigned a separate sensing element with associated part control device, and the deflecting element and tension beam are in one piece and extend over the entire website of the weaving machine.
  • a warp tension increase on one sub-warp beam a warp tension decrease occurs on the other sub-warp beam, because the continuous tensioning boom is pivoted further by the increase in one sub-warp beam.
  • 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 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 boom 14 is seated on a pivot lever 31, which is only indicated in FIG. 2 and which is connected at one end to a torsion spring bar 33 arranged in a stationary support boom tube 32.
  • 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 bar 33 twisted at one end.
  • the mode of action is as follows.
  • the spanning tree 14 can e.g. can be adjusted by appropriate pre-tensioning of the torsion spring rod 33 so that it is in the position shown in the extended position in FIG. 2.
  • 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 towards the sensor 23 arises. be about 20% of the magnitude of the voltage vectors E, F.
  • the tensioning tree 14 can be moved, for example by correspondingly stronger pretensioning of the torsion spring bar 33, into a work area which corresponds to the position 14a shown in broken lines.
  • the warp tension occurring at D and directed towards the tensioning tree in position 14a now corresponds to the vector E '. Therefore lies a much larger, corresponding to the vector G 'feel force of about 60 of the warp tension E'. This considerably increases the reactivity and thus the readjustment of the respective warp let-off speed.
  • the force relationships on the feeler roller 18 correspond to those on the feeler roller 16, as shown in FIG. 2.
  • the warp let-off control device can also be used in a continuous, single warp beam corresponding to the overall weaving width C. A single feeler roller 16 is then sufficient. On the other hand, the device can also e.g. can be used on weaving machines with three warp beams. Then three tracer rollers are required, one on each part of the warp beam.
  • the tensioning tree 14 can also be operated under the action of two laterally arranged spiral springs e.g. according to DE-PS 11 38 715.
