Definitions

  • the invention relates to 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, and 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 for tolerance of the synchronization in the at least one rotational angular position, a tolerance value is specified.
  • a control and regulating device in such a way that can be switched between a hard and a soft control.
  • the hard control which is used during the start of the loom, follows the second drive motor of the shedding device with precise synchronization of the first drive motor.
  • the soft control in which the drive motor of the shedding device may advance or lag the first drive motor with deviations from the synchronous operation.
  • a method for operating a weaving machine with a plurality of drive motors wherein the elements driven by the drive motors are each synchronized in at least one predetermined rotational angular 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.
  • 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, and a second drive motor which drives at least one second element and with a second rotary encoder is coupled, wherein the drive motors are controlled so that the elements are synchronized to each other in at least one predetermined rotational angle position, for a precision of the synchronization in the at least one rotational angular position a tolerance value is specified, and the size of the tolerance value is set in dependence of at least one Webparameters.
  • weaving parameters are available shot time, thread properties that affect average weft thread speed, weave weave, 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, for example, 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 operation. This can optimize energy consumption.
  • the driven elements such as a sley and shedding facilities
  • the driven elements are synchronized in a common zero point. If a first element passes through the zero point, then the second element may already have passed through it or lag behind the first element. For the advance or lag certain accuracy is required, which is determined by the tolerance value.
  • 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.
  • 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 set at least in accordance with a weave weave to be woven, with a greater tolerance value is selected for uniform weaves, as with 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 weave, the same amount of warp is 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.
  • the size of the tolerance value is also 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 the weft insertion is started at a later time 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 also 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 from shot to shot, for example.
  • At least three levels of tolerance values "low", “medium” and “high” are predefined.
  • a selection of the level of the tolerance value takes place as a function of one or more weaving parameters.
  • a tolerance value can be continuously adapted to specific weaving parameters. For example, certain weaving parameters and associated tolerance values can be determined in advance and stored in a table. The tolerance value is set individually in one embodiment for each weaving cycle and / or each weft thread to be inserted. It is conceivable to vary the tolerance values depending on the weave pattern, even with unchanged weaving parameters, in order to intercept fluctuations of the weaving machine. Thus, it is conceivable, for example, to store the tolerance values for ten successive shots in a tolerance value sequence and thus to make them available.
  • the tolerance value is set in a forward-looking manner.
  • a weave pattern or additionally, a weft thread type to be introduced in regions can be taken into account and the drive of the second drive motor can be converted to the changed weaving parameters in this way.
  • 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.
  • the first element and / or the second element are synchronized to form an imaginary synchronization wave.
  • the imaginary synchronization wave is thereby "operated" with nominal values.
  • a control and / or control device for driving drive motors of a weaving machine with at least one first drive motor which drives at least a 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 control and / or control means comprises means by which the drive motors are controllable such that the elements are synchronized with each other in at least one predetermined rotational angle position, a tolerance value can be predetermined by the regulating and / or control device for accuracy of synchronization in the at least one rotational angular position and the regulating and / or control device Has means by which the size of the tolerance value in dependence of at least one web parameter can be determined.
  • Information about a weave to be woven is present in the control and / or regulating device, so that the size of the tolerance value can be determined as a function of the weave weave to be woven, with a greater tolerance value being selected for regular weaves than for irregular weaves.
  • the control and / or control device is also used, for example, to control the drive motor for the shedding device.
