  • the speeds of the individual cylinders of the drafting system must also be in a defined relationship to one another.
  • the speed of movement of the ring rail and the ratio of this speed to the forward speed are important for the formation of twine on the tubes.
  • the kinetic energy of the spinning or twisting organs is used for energy recovery and for supplying the auxiliary units that normally come to a standstill more quickly in the event of a power failure.
  • the electric motors of the spinning or twisting organs act as a generator.
  • the invention has for its object to provide a textile machine of the type mentioned, in which the energy required for a defined spinning operation in the event of a power failure is provided with the least possible effort and in particular without special complex emergency units such as buffer accumulators of larger capacity.
  • the object is achieved according to the invention in that an additional buffer battery assigned to the electrical intermediate circuit is provided, and that this buffer battery can only be connected to the electrical intermediate circuit after the speeds or speeds have fallen below a predeterminable minimum value (n min ) in the lower speed or The speed range has dropped or the intermediate circuit voltage has reached a corresponding minimum voltage value, which is smaller in comparison to the voltage when the mains is supplied.
  • a drafting system that has a low effective persistence does not come to a standstill even in the event of a power failure, but at least for a defined spinning operation while maintaining predeterminable speed ratios down to the range of zero speed with the required speed Energy is supplied.
  • Such an automatically set emergency voltage supply can also be used to maintain a controlled movement sequence for other drives such as a ring bench or the like for a sufficiently long period of time.
  • the drive system supported by the intermediate circuit in generator mode in the event of a power failure comprises at least one frequency-controlled electric motor
  • the minimum voltage value or the battery voltage which determines the transition to battery buffering is dependent on the just permissible one Voltage / frequency ratio of the frequency-controlled electric motor is selected.
  • the backup battery is preferably connected to the intermediate circuit via a diode, a thyristor or the like.
  • the diode is polarized such that the backup battery is decoupled as long as the intermediate circuit voltage is greater than the battery voltage.

  • the lower rigidity of the drafting system does not come to a standstill in the event of a power failure, but is controlled and can be controlled down to zero speed, preferably in synchronism with the other drives in accordance with a predeterminable sequence control.
  • the respective speeds or speeds of the loads in question, as well as their respective speed or speed relationships, in particular also during spinning control in the event of a power failure, can only be predetermined by the electronic control.
  • the drive systems preferably include electric motors that can be controlled via frequency converters.
  • a frequency converter can be formed, for example, by a rectifier and an inverter.
  • the target frequency, to which the assigned electric motor adjusts itself accordingly, can then be specified via the electronic control, for example, to the relevant inverter.
  • the drive system assigned to the drafting system and / or the ring bench and that to the spindles assigned drive system is supplied with energy from the supply network by a common rectifier via a DC link, the emergency power supply being provided via this DC link in the event of a power failure.

  • the ring bench can be driven and controlled separately for variation, in particular of the spindle / ring bench speed ratio that can be predetermined.
  • the spindles can be driven in groups or by individual motors, with these individual motors or the motors of a group preferably being assigned common frequency converters.
  • the drafting system can be assigned its own drive system with several drives. It is conceivable to move the ring bench either together with the drafting system or with its own drive. While each spinning station is normally assigned its own spindle, the drafting system and the ring bench can each extend over several spinning stations, expediently over the entire length of one machine side.
  • Corresponding drafting system strands and the two ring banks can be controlled together.
  • the electronic control normally has a very low energy requirement, it can, for example, only be battery-backed in the event of a power failure. In principle, however, it is also conceivable to provide an emergency supply via the drive system which may be operating in generator mode and which is assigned to the loads with the greatest effective persistence.
  • the drive system associated with the drafting system and preferably the ring bench can only be reduced down to a predeterminable minimum drafting cylinder speed not equal to zero and then at least decoupled from the drafting arrangement. After this, the drafting system immediately comes to a standstill, the spindles in question can generally continue to turn slightly. Due to the relatively low speed, this has practically no effect. However, it is conceivable to additionally brake the spindles.
  • the embodiment of a ring spinning machine shown comprises two (only partially shown) drive systems 10, 12.
  • the first drive system 10 is used to drive the spindles of the ring spinning machine (not shown).
  • the second drive system 12 is assigned to two drafting systems and two ring banks on the two ring spinning machine sides and for this purpose comprises three drives.
  • the drive system 12 assigned to the drafting systems and the ring banks and the drive system 10 of the ring spinning machine assigned to the spindles are supplied with energy by a common rectifier 14 via a DC intermediate circuit 16 from a supply network indicated by a line 18.
  • the drive system 12 is first supplied with emergency power by energy recovered from the drive system 10 and then all systems 10, 12 are supplied with emergency power by a ground 62 on the one hand and a diode 60 to the DC link 16 on the other hand connected backup battery 58.
  • the drive system 10 has an asynchronous motor 24, 26 which is speed-controlled in normal operation via a supply frequency for each spindle (only two are shown in the figure).
  • the asynchronous motors 24, 26 for the spindles is a frequency converter 14, 28; 14, 30 assigned, which in addition to the rectifier 14 is also formed by an inverter 28 and 30, respectively.
  • An electronic control 56 is also provided, by means of which, in particular, the inverters 28, 30 of the spindle drive system and inverters 50, 52, 54 of the second drive system 12 assigned to the drafting systems and the ring banks can be controlled.
  • the control outputs of the electronic control 56 and the control inputs of the inverters are identified by the letter S.
  • asynchronous motors 24, 26 of the drive system 10 for the spindles are shown in the drawing, up to 600 spindles per machine side and a corresponding number of spindle motors 24, 26 can be provided in practical use with a ring spinning machine.
  • the individual motors can be connected to a common frequency converter in the machine end head via an energy distribution system.
  • the spindle can also be driven in groups or even by a single motor via tangential belts.
  • a mechanical coupling for determining the speed ratio between the spindles and the assigned drafting systems is missing. This ratio is only determined by the electronic control 56.
  • the second drive system 12 for the two drafting systems and the two ring banks on the two machine sides three different drives with the frequency converters 14, 50; 14, 52 and 14, 54, which are formed by the common rectifier 14 lying between line 18 and line 16 and the individual inverters 50 to 54. Accordingly, the three drives of the second drive system 12, like the spindle drives, are supplied with energy from the line or the network 18 by the common rectifier 14 via the direct current intermediate circuit 16.
  • the inverters 50, 52, 54 of the three drives of the second drive system 12 for the drafting systems and the ring banks are each connected to the line or the DC link 16. These inverters 50 to 54 can also be controlled by the electronic control 56, as indicated by the arrows S.
  • One inverter 54 is assigned to an asynchronous motor 48 for driving the two ring banks.
  • the speed of movement and the sequence of movements of the ring banks in relation to the spindles are important for the construction of the cop.
  • the respective coordination is carried out by the electronic control 56.
  • the two drives having the inverters 50 and 52 are drafting system drives.
  • the precise running of the drafting system cylinders in relation to each other and to the spindles is of crucial importance for warping and yarn counting.
  • synchronous motors 32 to 46 are preferably used as drafting system motors.
  • the structure of the two drafting system drives 50, 52 is explained in more detail below:
  • the ring spinning machine has two drafting systems, one on each machine side.
  • Each drafting system comprises a front or delivery cylinder, a central cylinder and a rear or input cylinder. Due to the specified length (eg over 300 spindles per machine side), the cylinders are driven from both ends in order to avoid yarn defects due to torsional effects in these cylinders along the machine. A division of the cylinders in the middle can also be provided everywhere. Accordingly, two electric motors, in the present case synchronous motors, are provided for each drafting system delivery cylinder.
  • the four motors 32 to 38 assigned to the inverter 50 are the following drafting unit drive motors:
  • the two synchronous motors 32, 34 are assigned to the two ends of the delivery cylinder on one side of the ring spinning machine, while the two synchronous motors 36, 38 are assigned to the two ends of the delivery cylinder provided on the other side of the ring spinning machine.
  • the common inverter 52 is provided for the four synchronous motors 40 to 46.
  • the two synchronous motors 40, 42 are assigned to the two ends of the rear or center cylinder on one side of the ring spinning machine, while the two synchronous motors 44, 46 are assigned to the two ends of the rear or center cylinder on the other side of the ring spinning machine.
  • Rear and center cylinders on each machine side are each one Cylinder group combined and connected to each other via a change gear.
  • separate drives can also be provided for central and rear cylinders.
  • the electric motor 48 assigned to the two ring banks can be an asynchronous motor, for example.
  • a toothed belt transmission, a clutch and a gear transmission can be provided between a respective motor shaft and a relevant drafting cylinder end.
  • the arrangement of a brake between the clutch and the gear transmission is also conceivable, for example to prevent the delivery roller from turning back after a spinning process.
  • the toothed belt transmission serves as a damping means which absorbs impacts emitted by the motor in question at low speeds and thus protects the sensitive gear transmission in the area of the drafting roller.
  • the toothed belt transmission is used for speed transmission in order to reduce the relatively high speed of the motor in question to a lower value at the input of a clutch in question.
  • the gear transmission is used together with the toothed belt transmission for torque transmission, so that when a respective clutch is engaged, the corresponding motor is not loaded with the high moment of inertia of the stationary cylinder.
  • the power supply during such a power failure is initially provided by the asynchronous motors 24, 26 of the spindles which operate in normal operation like the other motors via a supply frequency, but in the event of a power failure to supply the second drive system 12 via the DC link 16 in over-synchronous operation as generators. Accordingly, the fact is exploited that the spindles have a relatively large effective steadiness compared to, for example, the drafting system or the ring bench, and the kinetic energy available can be used to feed electrical energy back into the DC link.
  • the inverters 28, 30 are designed for such energy recovery.
  • the electronic control 56 comprises a spinning control, which is also activated in the event of a power failure, in order to drive the drive systems 10, 12 down to at least approximately the range of the speed or speed while maintaining defined speeds or speeds and speed or speed ratios.
  • the downward control to lower speeds must take place in such a way that the asynchronous motors 24, 26 can initially work as generators after the power failure occurs.
  • the electronic control 56 in contrast to the second drive system 12, requires only relatively little energy for the drafting systems and ring banks to be kept in operation, it can basically only be battery-backed. However, this is not absolutely necessary. Rather, this electronic control 56 can also be supported at least temporarily by the drive system 10 assigned to the spindles.
  • the speed or speed ratios can also be predetermined by the electronic controller 56 during the sequence control that begins, for example, in the event of a power failure.
  • the buffer battery 58 additionally assigned to the DC link 16 serves to support the DC link 16 in a lower speed range.
  • the negative pole of the buffer battery 58 is connected to ground 62 and its positive pole is connected to the DC link 16 via the diode 60 switched in the forward direction.
  • the voltage of the buffer battery 58 is selected such that this battery is only switched on via the diode 60 after the speeds or speeds, in particular of the drives of the drive system 12 to be supported, have dropped below a predeterminable minimum value n min (see also FIG. 2) . This means that the voltage of the buffer battery 58 is significantly lower than the voltage present at the DC link 16 with normal mains supply.
  • the voltage of the buffer battery 58 is to be selected such that, taking into account the voltage drop across the diode 60 at the DC link 16, it generates a voltage which is clearly above the critical voltage value, but on the other hand is so low that the capacity of the buffer battery 58 is kept relatively small can and in the event of a power failure before the backup battery 58 is switched on, the drive system 12 is first supplied by the energy recovered from the drive system 10 by the spindles.
  • the electric motors 32-48 and 24, 26 of the drive systems 12, 10 are generally operated at relatively high speeds, which is indicated in FIG. 2 by the speed value n0. While a single such speed value n0 is indicated in the diagram according to FIG. 2, the various Drive motors actually operated at least partially at different speeds.
  • n St is shown in the diagram according to FIG. 2 to represent the speed curve of the drafting system
  • the different drafting system cylinders of the drafting system actually rotate at different speeds in order to generate the respective distortion.
  • the drive system 12 assigned to the drafting system and preferably also to the ring bank is first supplied via the DC intermediate circuit 16 by the drive system 10 operating in generator mode, via which energy is returned to the DC intermediate circuit 16.
  • the asynchronous motors 24, 26 can operate as generators in the oversynchronous mode, their supply frequencies must be reduced accordingly.
  • the synchronous motors 32-48 must also be controlled accordingly.
  • the emergency power supply to the drafting system and preferably also to the ring bench associated drive system 12 by the energy recovered from the drive system 10 of the spindles does not follow until the machine comes to a standstill, but only up to a minimum speed n min at which the energy supplied from the drive system 10 is still sufficient for controllable operation of the synchronous motors 32-48.
  • the buffer battery 58 is switched on via the diode 60 (see FIG. 1). That is, the voltage of the buffer battery 58 is selected to be at least as large as the minimum voltage determined by the critical voltage / frequency ratio plus the voltage drop across the diode 60. A certain safety distance must be taken into account. On the other hand, the battery voltage should not, however, be much greater than the required voltage, so that at speeds greater than the minimum speed n min following the power failure that occurs, the emergency power supply takes place via the spindle drives 24, 26 which operate as generators in over-synchronous operation.
  • the battery backup takes place in the lower speed range BP, so that, as shown by the solid curve n1, during the entire spinning control until the machine finally comes to a standstill at time t St, it is possible to control all drives without problems and thus to maintain predetermined speed ratios.
  • the backup battery 58 can be connected to the DC link 16 instead of via the diode 60, for example also via a thyristor or otherwise.
  • provision can be made to uncouple at least the drafting system from the assigned drive system before the speed reaches zero.
  • FIG. 3 shows the possibility of connecting a buffer battery 58 ′ or generally an accumulator via a DC / DC converter, so that a higher voltage in the intermediate circuit 16 can be achieved.
  • Normal lead accumulators or capacitor batteries can be used as buffer batteries.
  • converter 54 ' the lower voltage of the backup battery is converted to a higher voltage in the intermediate circuit.
