Apparatus for automatically switching off and disconnecting an electric motor shaft drive accelerating a winding bobbin once a circumferential cylinder drive has become effective |
摘要 |
A circuit for automatically disconnecting a shaft drive spinning a textile winding bobbin and automatically substituting a circumferential cylinder drive for the shaft drive is disclosed. The cylinder drive becomes effective a short time after the start of the textile winding process. A signal proportional to the torque of the shaft drive motor is stored in a storage amplifier shortly after the start of the winding process. If the continuously measured instantaneous current value of the shaft drive exceeds, when both drives operate in parallel, the stored current value, a command to switch off the shaft drive is given.
