Definitions

  • the invention relates to a textile machine, in particular carding machine, track or combing machine, with at least two with respect to their speeds corresponding to a master functionality matched electrical drives for driving machine elements, in particular fiber material delay elements, measuring elements, transport elements and / or storage elements, and at least one measuring device for Actual value recording of drive and / or fiber material-related measured quantities.
  • DE 29 41 612 C2 discloses a Strekke for Doubling and warping of slivers with a drafting system, which has driven by separate electric motors pairs of rollers whose speed ratios are adjustable by means of frequency divider.
  • a central computer unit continuously calculates the sliver mass of the continuous sliver and specifies target speeds for the various pairs of rollers.
  • the master-slave principle is used.
  • single drive is to be understood here that a plurality of drives are provided, of which one drives one or more axes.
  • a real motor axis is defined as a master, with the remaining axes of the electric drives following the speed ratio specified by the master.
  • a virtual master is set up that generates setpoint values without any deviation from the theoretically ideal form.
  • all slaves are synchronized by a clock signal from the virtual master to the same sampling time.
  • Both the real and the virtual master poll the slave drives at regular intervals during operation (so-called polling), the corresponding data generally being transmitted via bus connections.
  • a disadvantage of these textile machines is that the use of the known master-slave principle can not ensure that all drives are operated in optimal synchronization with each other.
  • the master functionality can change according to the respective conditions.
  • the master function can be assigned by the at least one control and / or regulating unit according to the invention currently each one of several drives.
  • a virtual master can also specify the engine speeds. This results in the possibility that at different times different drives serve as the current master.
  • the master function can be passed on - and, if necessary, transferred to a virtual master.
  • the actual values are preferably transmitted to the control and / or regulating unit designed centrally or locally, which determines the instantaneous master on the basis of these values.
  • this unit also provides the corresponding new setpoint speeds-possibly taking into account further parameters-for the drives.
  • the values for measuring the strip cross-section before the drafting system flow into the calculation of the setpoint rotational speeds.
  • the determination of the master functionality on the one hand and the specification of the new setpoint speeds on the other hand can also be distributed to different units.
  • the momentarily weakest drive takes on the role of the master in order not to overload this drive, for example, or - for the example of a regulating section - to obtain a continuously good strip quality.
  • control and / or regulating unit receives the instantaneous actual values from the corresponding measuring device (or signals derived from these actual values or preprocessed signals).
  • the control and / or regulating unit receives the instantaneous actual values from the corresponding measuring device (or signals derived from these actual values or preprocessed signals).
  • the instantaneous band cross-section fluctuations Preferably from this - at a regulating distance, in particular taking into account the instantaneous band cross-section fluctuations - immediately calculated the target speeds for the other drives and passed on to the drives.
  • limit values makes sense, since, for example, when measuring the motor current consumption within certain actual value ranges of a currently functioning as a slave drive, there is no need to make this the master drive. Only on the other side of the corresponding limit value does the current consumption measuring element of this drive signal that this drive can not follow the current requirements and therefore usefully takes over the master function so that the other drives can follow it.
  • no continuous or periodic querying is performed by the control and / or regulating unit according to the invention.
  • the current master-slave distribution corresponds to the current drive requirements - is such a query by the control and / or regulating unit is not necessary.
  • instantaneous actual values recorded by a measuring device-if necessary after a preparation-are preferably only transmitted when they are outside a predetermined value range.
  • Different measured variables can be measured by means of suitable measuring devices whose actual values (or signals derived therefrom) are transmitted to the control and / or regulating unit determining the master functionality. So can In particular, measuring devices for measuring the rotational speeds of the drive axles or speed changes can be provided. Alternatively or additionally, torques, the motor currents of the drives, the phase shift and / or the phase angle of the drives, the rotational speed or its time derivative and the engine temperatures can be measured. Alternatively or additionally, for example, thick areas and / or fiber material properties are measured by means of measuring devices or sensors.
  • a touch roller signal to the sliver cross section (there are also the terms sliver mass, fiber sliver thickness or sliver volume known)
  • this signal can be used on the sensing roller to a virtual master, for example, in a control and / or Control unit can be integrated, which allows all drives and thus the entire machine to run slower to ensure a precise delay at the lower delivery speed. It is also possible to perform warpage measurements on the sliver (s) to be drawn. Generally speaking, actual values can be measured to measured variables that are related to the drives or the fiber material or the drawing.
  • the invention can be used in textile machines and in particular in Soinnereimaschinen with a drafting system, in which at least two drives are provided. These drives drive either a single or multiple elements. Such drives may be provided at a distance in particular for take-off rollers at the drafting input, input rollers, center rollers and / or output or delivery rollers of the drafting system, take-off rollers at the drafting system, a turntable above a can, and a rotating or iridescent can stand surface for a tray to be filled.
  • several of the aforementioned elements can be driven by a single motor. For example, a motor for the pair of output rollers and for the subsequent calender roller pair (take-off roller pair) can be used.
  • a second motor may drive a traction roller pair upstream of the drafting system as well as the input roller pair and the middle roller pair of the drafting system.
  • a third motor can act as a retraction drive, this drive is used in particular for removing the master tapes from the feed cans.
  • a fourth drive then drives, for example, the turntable and the can footprint. Various variations of such a construction are possible.
  • the strip cross-section measured values measured upstream of the drafting system are expediently transmitted to a regulating computer which calculates the setting values or setpoint values for the drafting system drives.
  • These target values are then forwarded within the scope of the invention to the control and / or regulating unit which, depending on the instantaneous actual values (ie of the current master), optionally adapts these setpoint rotational speeds and, if necessary, modifies the setpoint rotational speeds the drives pass on.
  • the control and / or control unit thus takes over the synchronization of the drives.

  • This situation can be interpreted in the context of the invention to the effect that the currently weakest drive briefly acts as a master, after which the other drives must be directed. If then the speeds are further reduced, it can be seen in a transfer of the master function by a virtual master.
  • the duration of the dynamic reduction can be based on the momentarily weakest drive as well as, for example, its degree of overload.
  • the dynamics of the machine is much higher, so that the delivery speed of the track leaving fiber sliver changes frequently, however, results in high productivity.
  • the communication between the individual drives with each other and / or with a central control and / or regulating unit takes place in a preferred embodiment by means of bus connections. It makes sense here to use a parallel or serial bus system, a CAN bus, a Profibus or an Interbus. Alternatively, individual connections are provided by the measuring device or devices to the at least one control and / or regulating unit, which can be designed both as digital and as analog lines.
  • this drive can take over the master function, so that the speeds of the other axles are matched to the mentioned limit:
  • this drive expediently also takes over The master function, so that the remaining drives are reduced to maintain the speed synchronicity according to their own capabilities.
  • the master may preferably be changed several times, this change advantageously being directed to the energy content of the respective driven machine parts.
  • the inventive assignment of the master functionality when starting and / or stopping the machine is made.
  • the master function can be assigned up to a certain delivery speed of the warped sliver or up to a certain power consumption of this drive to then leave the master functionality in normal operation to another drive or a virtual master.
