Definitions

  • the invention relates to a method according to the preamble of patent claim 1 and a thread-processing system according to the preamble of claim 5.
  • the yarn feeding devices supplying the various channels conventionally operate as autonomous units.
  • the speed control unit of the yarn feeding device taking into account the instantaneous drive speed and with the aid of signals from several sensors scanning the yarn, calculates the amount of yarn required to cover the instantaneous consumption and therefrom deduces and sets the drive speed for the current consumption always provide a sufficient amount of thread in the thread supply. It is also possible to include the behavior of the yarn supply in the recent past and up to the current calculation time. The future consumption development can not be considered.
  • the yarn sensor device comprises at least two yarn sensors, which requires a high and cost-intensive equipment expense. Since in the autonomous operation of the yarn feeding device, the future, z. B.
  • the current thread consumption covering yarn amount is calculated on the basis of signals of the speed signal generator, a yarn supply sensor and a yarn withdrawal sensor and set the speed for the drive motor.
  • the delivery device works autonomously according to the current thread consumption by the loom and is not connected to the main control unit of the loom.
  • the speed signal generator supplies a speed signal corresponding to the incoming thread quantity.
  • the thread run sensor supplies signals for the amount of thread running.
  • the thread supply sensor signals the achievement of a maximum allowable and a minimum allowable thread size. From the comparison of the incoming thread amount and the amount of thread running a difference is determined whose sign is used to accelerate or retard the drive motor.
  • the signals from the yarn supply sensor override this speed control by stopping the motor at a maximum signal and bringing the motor to maximum speed with maximum acceleration at a minimum signal.
  • At one off EP-A-0458856 known thread-processing system of an air-jet weaving loom and at least one measuring delivery device data related to the weaving pattern data from the main control unit of the air-jet loom are transmitted in a fast communication bus system to a control of the measuring supply device.
  • several preparatory acceleration and deceleration routines for the drive motor are stored.
  • the control selects a suitable preliminary acceleration or deceleration routine depending on the information of the weave pattern and initiates it for the drive motor to allow the measurement delivery device to adjust to the operating phase in the channel for consumption-dependent drastic accelerations or deceleration To avoid delays of the drive motor.
  • the data transmitted to the control is not used to calculate a consumption-covering amount of thread.
  • the invention has for its object to provide a method of the type mentioned above and a yarn processing system, which make it possible to improve the performance of a yarn feeding device and to simplify its structure.
  • Speed control not only takes into account the recent past to the present, but also a section from the future.
  • the speed is already controlled in advance with a view to a possible drastic increase in consumption or consumption so that when the consumption change occurs no extreme acceleration or deceleration of the drive motor is required more.
  • the consumptive amount of thread is calculated for each future shot to derive therefrom the appropriate speed, or is alternatively calculated for several consecutive future shots. Then the speed is turned off.
  • the drive speed is controlled so that at a precalculated time a signal change of the thread sensor must occur, if the thread delivery is done properly.
  • a detected time deviation of the signal change from the predicted time can be used to derive speed corrections if the weaving machine is not operating according to the transmitted data or the drive motor should not run as controlled. It is a cost effective, easy to use drive motor usable. From the flexible and harmonic speed control results in a reduction in the risk of yarn breaks and thus improve the performance.
  • only one thread stock sensor means a considerable simplification.
  • the drive motor can be simpler.
  • the overhead of the data link from the main control unit of the rapier or projectile weaving machine to the speed control unit of the yarn feeding apparatus and the formation of the speed control unit for calculating the consumptive yarn amount from the entirety of the signals are negligible.
  • the data for the future working phase of the rapier or projectile loom in the respective channel are present with precise timing anyway, because they are used in this type of weaving machine for controlling the channel or color selection. It also does not pose a problem for a future data To program the working phase of the rapier or projectile weaving machine so that they represent timely, meaningful information for the speed control in each yarn feeding device.
  • the consumption and speed-dependent behavior of the yarn supply is monitored on the basis of the movement of its deduction-side limit at a reference position.
  • the sensor signals either change depending on whether the thread supply is present or absent at the reference position, or may even vary analogously. These sensor signals are used with the loom data to calculate the thread length, but optionally only to confirm the calculation and / or to correct the calculation. Since, thanks to the consideration of the future working phase in this channel, the speed of the drive motor of the yarn feeding device is flexibly and preparatory controlled, relatively small fluctuations of the yarn supply size to the reference position can be maintained, ie a permanently optimally small yarn supply size, the emptying of the storage body, or overfilling , avoids.
  • the data of the future working phase in the channel of the yarn feeding device can each be transmitted in the form of a time and / or a period of time.
  • these data could represent certain angles of rotation or ranges of rotation, for example, of the main source of the rapier or projectile weaving machine, which are transmitted to the speed control unit of the delivery device along with the incrementally subdivided rotation of the main shaft.
  • Data important for the correct calculation may be included in the following group: shot start time or time to shot start, shot end time; Shot duration, number of shots, pauses between consecutive shots, machine running speed, shot length, and the like; d. H.

  • the yarn supply sensor is arranged for example on the housing arm 12 and aligned with a scanning zone on the storage body 3, in which the withdrawal-side boundary of the yarn supply YS should be positioned approximately (reference position) when the yarn supply has an optimal size.
  • a thread amount is understood with the emptying of the storage body 3 is excluded even at maximum consumption by the loom L, but also overfilling at a consumption stop. That is, the optimum size of the yarn supply YS is as small as possible.
  • the yarn supply sensor S generates different signals depending on whether the discharge limit of the yarn supply YS is present in the scanning zone or not.
  • the thread supply sensor S even works analogously.
  • a data transmission path 5 is provided between the main control unit C and the speed control unit CU, via which data is transmitted to at least one future working phase of the loom L in information i '.
  • the data link 5 may be formed by cable or as a wireless radio link.
  • the transmission link 5 is part of a Bus system that transmits the data in the form of serial messages with a fast communication protocol (eg CAN bus system).
  • a fast communication protocol eg CAN bus system
  • the speed control unit CU and the main control unit C would be assigned to CAN interface processors. At least a majority of the data representing the future working phase of loom L should be included in the highest priority messages.
  • an input part 6 could be provided, with the information on the shot length or weaving width, the diameter or the circumferential length of the storage body 3, the weaving machine operating speed and the like. Entered to this information as data to the speed control unit CU to submit.
  • the input part 6 'could also be provided on the delivery device F, e.g. at the speed control unit CU, be provided.
  • the other weft threads Y ', Y ", Y"' are supplied in further channels of other delivery devices F, not shown, which are also each equipped with only one thread supply sensor S and connected to the main control unit C.
  • the loom L runs at a predetermined operating speed (rotational speed of its main shaft), wherein the weft threads are intermittently registered in the compartment, by means of grippers or projectiles R.
  • the respective entry member R takes over weft held in the channel or color selector A to register it before it is struck and cut off by the reed.
  • the weaving width and the working speed are set in advance, for example, in the input section 6.
  • the pattern-dependent sequence with which the weft threads are inserted is controlled by the main control unit C by the information i for the channel or color selector A.
  • the delivery device F holds on its storage body 3 the yarn supply YS ready, which serves to cover the consumption and is supplemented by the speed control of the drive motor M respectively so that the withdrawal-side boundary of the yarn supply is held at least approximately at the scanning position of the yarn storage sensor S.
  • the speed control unit CU receives data which is contained in information i 'for at least one future working phase of the loom L. On the basis of these data, also with data of the speed signal generator D and the data input at the input section 6 or 6 ', the speed control unit CU calculates, if necessary also considering the signal data of the yarn storage sensor, the amount of yarn required to cover the consumption on the storage body 3
  • the speed of the drive motor M is derived from the calculated amount of thread via a suitable algorithm and varied or adjusted accordingly.
  • the behavior of the thread stock in the past (before the calculation time, the size of the thread stock in the present) at the time of calculation, and also the future behavior of the thread stock in the future (for the future Working phase of the loom L) considered.
  • the signal changes of the thread storage sensor may be taken into account in the calculation, but may also be used mainly only for confirming the correctness of the calculation or for correcting the calculated thread quantity and for the speed control, if deviations between the calculated ratios and the actual conditions occur and should be determined ,
  • the data in the information i ' relates, for example, to the time of starting a shot in the channel of the yarn feeding device F according to the present, the duration of the shot or weft length for the shot, the end time of the shot, the pause to the subsequent shot, and the like. It is also possible to transmit the instantaneous working speed of the weaving machine, the weaving width and the like.
  • the speed control unit CU can first calculate the consumption-covering thread quantity and control the respective optimum speed of the drive motor from this. Since the data of the transmitted information i ' also represent at least one future working phase of the weaving machine L, the speed control can be adapted to the future consumption development.
  • the speed of the drive motor is reduced, because then in any case sufficient time will be available to the thread supply YS to the required Minimum size to bring.
  • the drive speed of the drive motor M is set higher from the outset to take account of the then high consumption in advance without any problems. This prepared speed control is also useful for a future consumption stop for a longer time, or in the case of a very high consumption, to avoid strong accelerations or delays of the drive motor, which could be harmful to the Y thread.
  • Fig. 2 schematically shows the behavior of the yarn supply YS over time t.
  • the speed control unit CU has, for example, stored information about the previous behavior of the yarn supply YS in the past P.
  • the horizontal, dashed line represents, for example, the scanning zone (reference position) of the yarn supply sensor S.
  • the discharge-side boundary of the yarn supply YS should expediently fluctuate only slightly in this scanning zone.
  • the speed control unit CU knows at time x (presence T) that the next shot P1 will start at time x1 and then last for a time x2 and end at time x3. Thereafter, a pause x4 will occur until the start time x5 of the next shot P2.
  • At least the data on the working phase, eg between times x to x3 are transmitted, expediently even up to the time x5 or even further into the future E.
  • the speed control unit CU knows exactly how the thread consumption will develop and how the consumption-covering thread quantity in the yarn supply YS, and from this the speed of the drive motor can be controlled.
  • each delivery device works as an autonomous unit that has no connection to the weaving machine except with the thread and reacts with multiple onboard thread sensors on the current consumption-dependent thread supply development and accelerates the drive motor according to the sensor signals or delayed or stopped, and so far without direct information about future work phases in the loom.
  • this autonomous principle is in the described yarn processing system S of Fig.
  • the delivery device F now works with a single yarn supply sensor S and in strict dependence on the operating phases of the loom L, because its speed control unit CU is functionally linked to the main control unit C of the loom L. Without the information i 'and the data contained therein, the delivery device F would not be able to function with only a single yarn supply sensor S, since the speed control device CU would then not be able to guarantee the necessary consumption cover.
  • the data transfer to the speed control unit CU, the software-side preparation and the processing of the data transmitted mean only a negligible overhead for the delivery device, compared to the structural simplification thanks to the single thread storage sensor.
  • the drive motor M with its control circuits can also be designed more simply, since the speed control is more flexible thanks to the forward-looking information about the working phases of the weaving machine and no extreme acceleration or deceleration phases have to be performed.
