Definitions

  • the invention relates to a method for controlling drive motors of a weaving machine with at least one first drive motor which drives at least one first element and is coupled to at least one first rotary encoder, a second drive motor which drives at least one second element and is coupled to at least one second rotary encoder. wherein the drive motors are controlled so that the elements are synchronized to each other in at least one predetermined rotational angular position, and a tolerance value is specified for an accuracy of the synchronization in the at least one rotational angular position.
  • WO 2004/092467 A1 discloses a method for operating a loom with a plurality of drive motors, wherein the elements driven by the drive motors are synchronized in each case in at least one predetermined rotational angle position to an imaginary synchronization shaft.
  • Each of the elements and also each of the drive motors need not be exactly synchronized to a predetermined rotational angular position of the imaginary synchronization shaft. Rather, they can be synchronized with a tolerance to the predetermined rotational angular position of the imaginary synchronization wave. A value for this tolerance can be set differently for each weft entry.
  • the invention has for its object to provide a method for driving the drive motors of a loom, through which energy consumption is optimized. It is a further object of the invention to create a corresponding control and / or regulating device and an associated loom.
  • This object is achieved by a method for driving drive motors of a weaving machine with at least one first drive motor which drives at least one first element and is coupled to at least one first rotary encoder, a second drive motor which drives at least one second element and coupled to a second rotary encoder is, wherein the drive motors are controlled so that the elements are synchronized in at least one predetermined rotational angular position to each other, a tolerance value is specified for accuracy of synchronization in the at least one rotational angular position, and the size of the tolerance value is set in dependence of at least one Webparameters.
  • These weaving parameters are in particular an available shot time, thread properties which affect a mean weft thread speed, a weave weave, a weaving machine speed or the like.
  • the elements driven by the drive motors are to be synchronized with each other as accurately as possible, such a synchronization is usually associated with a high expenditure of energy.
  • the invention is based on the recognition that an exact synchronization or a synchronization with only a very small deviation is not always necessary.
  • a weaving parameter such as available shot time, fabric weaves, weaving machine speeds or the like, it is possible to perform a synchronization only to the extent that is at least sufficient for a weaving process. This can optimize energy consumption.
  • a synchronization may be necessary only at a single rotational angle position.
  • the driven elements such as a sley and shedding facilities, are synchronized in a common zero point.
  • the shedding device is synchronized relative to the angle of the sley to the start and / or end of a weft insertion with the sley.
  • the tolerance value required at the further rotational angle positions can deviate from the tolerance value in the first, synchronized rotational angular position.
  • the rotary encoders measure angular positions of the driven elements in one embodiment.
  • an angular position of the driving motor is measured and the value converted, for example, taking into account a gear stage to an angular position of the driven element.
  • a shedding device is driven by the second drive motor.
  • the first drive motor drives, for example, a sley, wherein the second drive motor can be operated in slave mode to the first drive motor. In other embodiments, both drive motors are operated in slave mode.
  • a drive motor for example, a tissue receptacle, an edge forming device, such as a Kanteneinlegevorraum, or other devices of the loom, which must be at least partially synchronized with other elements, in particular with the main shaft or the Webladewelle, driven.
  • the size of the tolerance value is adjusted as a function of a weave weave to be woven, with a greater tolerance value being selected for uniform weave weaves than for uneven weaves.
  • uneven bonds are fabric weaves in which the number of warp threads to be moved and thus, for example, weaving shafts to be moved change in successive picking cycles. For example, to weave a 1/1 fabric weave, the same amount of warp threads are moved up and down in each pick cycle. Such a movement is relatively uniform and a drive motor for driving a shedding device, such as a heald, will run relatively smoothly without control and / or control interventions with a certain tolerance.
  • the number of warp threads to be moved changes for each weft insertion, and thus, for example, the number of heddles to be moved.
  • Such a movement of the shedding device is comparatively irregular, so that changing driving forces and / or more control or regulating operations are necessary in order to operate the shedding device uniformly.
  • a lesser tolerance to be maintained is set to ensure that the shedding means is operated correctly.
  • a larger tolerance value can be selected, since usually fewer interventions are necessary here.
  • Such an adaptation of the tolerance value makes it possible, on the one hand, to increase the reliability of the shedding device in order to achieve better weaving results and, on the other hand, to increase energy efficiency. consumption, because unnecessary control and / or regulating interventions are avoided.
  • the size of the tolerance value is set as a function of the material of the weft thread.
  • the material of the weft thread can exert a not insignificant influence on the entry speed of the weft thread. If the compressed air entrains the weft yarn very well, as is the case, for example, with spun fiber yarns, larger tolerances can be permitted at the start and on arrival at the maximum available shot time. With “slow" weft threads, on the other hand, the entire shot time available for a weft insertion is required, so that only small tolerance values can be admitted at the correct starting time and at the correct time of arrival.
  • the available weft insertion time is generally sufficient even if weft insertion is started at a time later than the correct time. With a slow weft, however, the entire available weft insertion time for weft insertion may also be required.
  • a strong energy saving is possible by adjusting the tolerance value to the weft type in air jet looms. So it is conceivable, for example, that for a very fast thread tolerance deviation in the rotational angle position is tolerated by 20 °, whereas for a slow thread a maximum deviation in the rotational angle position is required by 5 °.
  • the size of the tolerance value is set as a function of a (mean) weaving machine speed, wherein at low weaving machine speeds a larger tolerance value is selected than at high weaving machine speeds.
  • a weaving machine speed for example a speed of 1200 rounds per minute
  • a relatively exact synchronization is required for a successful operation of the weaving machine.
  • low weaving machine speeds for example at speeds of 600 rounds per minute
  • a greater deviation in the angular position is tolerable.
  • the tolerance value can be adjusted, for example, from weft to weft.
  • a tolerance value is infinitely variable to specific weaving parameters
  • certain weaving parameters and associated tolerance values can be determined beforehand and stored in a table.
  • the tolerance value can be set individually for each weaving cycle and / or each weft to be fed in. It is conceivable, even with unchanged weaving parameters, to set the tolerance values as a function of the weaving cycle For example, it is conceivable to store the tolerance values for ten consecutive shots in a tolerance value sequence and thus make them available.
  • the tolerance value is set in a forward-looking manner.
  • a weave pattern or a weft thread type to be introduced in regions can be taken into account and the drive of the second drive motor can thus be converted to the changed weaving parameters.
  • the tolerance value for a transitional period is set to a low value. Even if the change of the weave pattern allows a loosening of the tolerance limits, this ensures that in the transition area weaving errors are prevented.
  • a transitional period is provided in terry cloth weaving machines when transferring from terry cloth to a normal fabric.
  • An adaptation to the changed weave pattern preferably takes place only after the definable transitional period. This also prevents instabilities from rapid changes of the weaving parameters due to multiple adjustments.
