Definitions

  • the invention relates to a method for operating a cheese-producing textile machine and a cheese-producing textile machine with a plurality of jobs, wherein at each workstation a single drive is formed by an electric motor and an associated control unit and the electric motor passes in the generator operation in case of failure of the supply voltage.
  • the DE 10 2005 035 055 A1 discloses a method according to the preamble of claim 1 and a textile machine with individual drives at each workstation according to the preamble of claim 6.
  • individual drives that operate in the generator mode after failure of the supply voltage occur in particular the rotor drives into consideration, which drive the spinning rotor at each workstation of an open-end rotor spinning machine. Due to the high rotational speeds of such a spinning rotor, the rotor drive, despite the relatively small rotating mass in case of power failure can apply enough electrical energy to at least temporarily supply its own control unit and a magnetic bearing often used in rotor drives.
  • the rotational speed of the rotor continuously decreases because the mechanical rotational energy is converted into electrical energy.
  • the generated electric power decreases.
  • the magnetic bearing function and the operation of the control device when passing a limit value of the generated power of the electric motor in the generator mode are no longer guaranteed.
  • the electric motor is short-circuited and thus braked. In this way, the electric single drive can be safely put out of service in case of power failure without damage.
  • the single drive has its own control unit that allows a substantially independent of a workstation control, not shown.
  • the WO 2007/085280 describes an electric motor drive a textile machine with a variety of electric motor driven workstations.
  • This drive is to enable a continuous recording of operating state data in order to be able to derive an error history from the stored data independently of its use on the textile machine.
  • Such operating status data can also be information about power failures or voltage drops.
  • the control of the drive not only has a RAM, that is a volatile memory, but also a flash memory, ie a nonvolatile memory in which the operating state data is stored.
  • the DE 10 2005 035 055 A1 and the WO 2007/085280 consider only the single drive and give no indication as to how to proceed with respect to the individual jobs of the textile machine in case of power failure.
  • a workstation control of each work site stores the production data of the workstation in a volatile memory. If the supply voltage fails, a backup of the production data is initiated. For this purpose, the individual drive supplies the workstation control with voltage until the production data from the volatile memory is saved in a non-volatile memory.
  • a volatile memory for example a RAM
  • a backup of this data took place in a non-volatile memory
  • the current production data would nevertheless be lost in the event of a voltage drop.
  • a fuse If the data is not detected until the power failure is detected, the time available for the backup is usually no longer sufficient for reliable data backup. Therefore, according to the present invention, the single drive energizes the workstation controller until the production data from the volatile memory is secured in a nonvolatile memory. In this way, the backup of the current data can be reliably guaranteed.
  • the production data are available on recommissioning, so that it can be carried out automatically.
  • the workstation control no longer immediately detects the power failure. Only the retroactive effect of the power failure on the production process can be detected for the workstation control on the basis of recorded production data. However, this is only possible with a certain time delay.
  • the control unit of the individual drive of the workstation controller advantageously signals the failure of the supply voltage and thus triggers the data backup process.
  • the control unit of the single drive detects the power failure without delay, since the single drive merges with this in the generator mode.
  • the production data can be saved in any non-volatile memory of the textile machine.
  • this may be an individual memory at each workstation associated with the workstation controller, or it may be a central memory for multiple workstations.
  • Autonomous individual drives of textile machines, as used in the WO 2007/085280 already have a non-volatile memory, preferably a flash memory. That is, an existing nonvolatile memory can be used, eliminating the need for additional hardware to back up the production data.
  • the electric motor of the single drive drives the spinning rotor of an open-end rotor spinning machine.
  • Such a single drive can provide sufficient electrical power for the method according to the invention, since sufficient kinetic energy is present due to the high rotational speeds of such spinning rotors.
  • Such production data can be the diameter of the cheese, the wound thread length, winding parameters, spinning parameters and / or details of the spin agent.
  • each workstation has a workstation controller with a volatile memory for storing production data, there is a nonvolatile memory for securing the production data in the event of power supply failure and signal means for initiating the backup, and the single drive is designed to supply the workstation controller with voltage for so long until the production data is saved from the volatile memory in the nonvolatile memory.
  • Fig. 1 an inventive cross-wound producing textile machine 1 is shown having a plurality of jobs 2.
  • the textile machine is designed as an open-end rotor spinning machine 1, in which each workstation 2 is equipped in each case with an open-end spinning device 3 and a winding device 4.
  • a sliver initially placed in sliver cans 5 is spun into threads, which are wound on the winding devices 4 to cheeses 8.
  • the winding devices 4 are equipped with a coil frame for rotatably supporting an empty tube or a cross-wound bobbin 8 and with a winding drum for rotating these elements.
  • the Fig. 2 2 shows a workstation controller 20 and a plurality of sensors and actuators, which are indicated by the symbol 22 and are in communication with the workstation controller 20 via communication lines 23.
  • the sensors detect state data of the workstation 2, such as the wound-up yarn length or the actual diameter of the cross-wound bobbin 8.
  • the condition data is continuously transmitted to the workstation controller 20 and stored in the RAM 21.
  • all data required for production at the respective workstation, such as spinning and winding parameters are stored in the RAM.
  • information on the spin agent which is mounted in the spinning device 3, stored in the RAM 21.
  • the spin agent in the case of the present rotor spinning machine a spinning rotor, is rotated by a single drive in rotation.
  • the individual drive has an electric motor 33, which is operated by means of its own control unit 30.
  • the electric motor 33 is magnetically supported.
  • the storage is indicated by the symbol 34 and is also controlled by the control unit 30.
  • the control unit 30 has a RAM memory 31 and a flash memory 32. In the flash memory 32 control programs and operating data of the drive are stored fail-safe. For ongoing operation, the RAM 31 is used.
  • the control unit 30 stands via the communication line 24 to the workstation control 20 in conjunction.
  • the textile machine 1 has a central power supply 10.
  • the sensors and actuators 22 of the workstation 2 are connected via the line 15 to the power supply 10.
  • the workstation control 20 is connected via the line 12 and the control unit 30 of the single drive via the line 11 to the supply voltage.
  • the line 14 should symbolize the connection of other jobs.
  • the switch 13 is closed during normal operation.
  • the electric motor 33 goes into generator operation.
  • the control unit 30 detects the power failure and opens the switch 13 via the control line 35.
  • a switch 13 is preferably a semiconductor switch, for example, a transistor used.
  • the electric motor supplies the control unit 30 with electric power, so that the magnetic bearing 34 can be maintained.
  • the work control is supplied via the lines 11 and 12 with voltage.
  • the control unit 30 signals the workstation controller 20 the power failure via the communication line 24.
  • the switch 13 can also be activated by the workstation controller 20. This then opens the switch 13 as soon as it was signaled the power failure.
  • the workstation controller 20 initiates the backup of the production data from its RAM 21 into the flash memory 32 of the control unit 30.
  • the single drive has enough energy to maintain the supply voltage until complete data backup. Only when the Speed of the electric motor has fallen below a predefined value, the electric motor is short-circuited by means of the control unit and shut down the job. When the voltage returns, the production data from the flash memory 32 is again loaded into the RAM 21 of the workstation controller 20. The workplace can thus resume production automatically.
