Definitions

  • the invention relates to a ring spinning machine according to the preamble of claim 1.
  • Ring spinning machines of this type where the production can be switched from one thread number to another in the short term, are particularly problematic in the event of a sudden power failure, which can occur several times a day in certain countries.
  • a central motor drives the common drive shaft of the spinning stations, which extends from the drive head, via a mechanical speed variator. Gears in the end head form the connection between the spinning unit drive shaft and the change wheels of the drafting systems. The drafting systems and spindles are thus directly mechanically connected. When the machine is at a standstill, all shafts of the drafting system are blocked by the self-locking of the coupled drives.
  • the single drive motors are fed together by one converter, while another converter supplies the drafting gear.
  • the division into two inverters is necessary because the spindle motors require a much higher frequency than the drafting drive motor due to their high speed.
  • the frequencies of the two inverters are determined by a common setpoint signal and are in a fixed relationship to one another, which determines the yarn twist. Changing the yarn twist is therefore no longer carried out on the gearbox, but purely electronically using the appropriate settings on the inverters.
  • all shafts of the drafting system are blocked by the self-locking of the coupled drafting system shafts.
  • a cross section through a drafting system 2 shows a feed roller 3, a center roller 4 and a take-off roller 5, which are driven together on each machine longitudinal side by corresponding shafts 8, 9, 10 which extend essentially over the entire length of the machine.
  • the non-driven pressure rollers 12 are in engagement with the rollers 3, 4, 5.
  • the embodiment shown allows the draft and thus the yarn number to be set electronically.
  • the incoming fuse 14 is warped in a pre-draft field between the rollers 3 and 4 with a fixed ratio, since the rollers 3, 4 are driven via a distribution gear 16.
  • the main warping occurs between the rollers 4 and 5 and is electronically adjustable by the speed ratio of the motors 19 and 20, so that the cross section of the yarn or thread 22 can be finally determined here.
  • Both motors 19, 20 are each supplied by individual inverters 24 and 25.
  • Another converter 26 jointly supplies the individual spindle drive motors 27.1-3 at the individual spinning stations 28.
  • the supply of all converters 24, 25, 26 takes place via a common DC intermediate circuit 30 (thick line), which is fed from the network 32 via a rectifier 33 .
  • the third embodiment is created by replacing the backstop 37 with a holding device 38.1, a conventional, mechanical single-disc spring pressure brake with an electromagnetic external trigger.
  • the preferred fourth embodiment variant is to electrically connect the holding device 38.1 to the intermediate circuit 30. As soon as the speed of all drives has dropped to zero, the voltage in the intermediate circuit 30 also disappears. Then the magnetic winding 40 of the holding device 38.1 is automatically de-energized, as a result of which the movable clutch disk 41 is pressed against the fixed clutch disk 42 by compression springs. The take-off rollers 5 are thus blocked.
  • a second, identical holding device 38.2 can be mounted on the shaft 9, also electrically coupled to the intermediate circuit 30.
  • FIG. 2 shows a further embodiment variant, in which one converter 45.1-3 is provided for each individual spindle drive motor 27. It would also be possible to arrange a converter for a group of individual spindle drive motors 27.1-3.
  • separate intermediate circuits can be provided on the one hand for the spindles and on the other hand for the drafting system, for example as shown in FIG. 2 of DOS 34 12 060.
  • a buffer battery and / or (according to CH 548941 or DE-A-34 42 080) flywheel can be provided in order to keep the parts with relatively high resistance in rotation.
  • the drafting system drive then also includes a direct current or direct voltage intermediate circuit and the triggering of the backstop or holding device can be made dependent on the state of these intermediate circuits.
  • the lock or holding device can be actuated (moved from the standby to the operating position) when the voltage in the intermediate circuit has reached a low level. This can take place automatically in that the lock or holding device can only be held in the standby position while the intermediate circuits have a predetermined energy state.
  • it can also be done indirectly via a sensor in that the sensor reacts to the state of the intermediate circuits and triggers the actuation of the lock or holding device.
  • Electrical energy for actuating the lock or holding device could be drawn from a memory or from another intermediate circuit. The necessary energy could also be available in non-electrical form, e.g. from a spring system or pneumatic energy storage.
