Definitions

  • the loop-shaped channel is filled with the strap very quickly. It is known that the motor of the feed device is switched off by the fact that at the end of the channel the beginning of the belt abuts a limit switch. It is not sufficient if the power supply to the motor of the feed device is switched off by the limit switch, because the motor is still running and is conveying further belt that is jammed in the channel. For this reason, the motor is switched off by the limit switch and additionally mechanically separated from the wheels of the feed device by a magnetic coupling. It is disadvantageous that the tape can be easily bent by the impact of the beginning of the tape against the limit switch. The magnetic coupling also wears out. It must be overhauled after a certain period of operation. The purchase price of the magnetic coupling is also considerable.
  • the invention has for its object to avoid a hard striking of the belt at the limit switch and a wearing clutch or other wearing parts in an electric drive of the feed device and also in the motor of the tensioning device also by avoiding mechanical, moving wearing parts solely by adjusting electrical quantities to produce precisely reproducible clamping forces in the band.
  • the sensor 13 reports to a control computer 15 built into the frequency converter 14.
  • This message has the effect that the frequency for the feed current of the motor 16 of the feed device is considerably reduced.
  • a position measuring device is now switched on. This consists of the light barrier 17, the light beam shining through several bores 18 of the wheel 6 lying on a circular line. Each time the wheel 6 is turned further by the distance between the bores, an electrical impulse is given to the computer 15. A much smaller subdivision of the distances is achieved if the gaps between a drive gear of the drive of the feed device are taken instead of the bores.
  • Three-phase motors are used for the invention, as are commercially available for 50 Hz mains current. To increase performance, the motors are also operated briefly at frequencies up to 70 Hz and also with overvoltages.
