Definitions
- the invention relates to a switch-off device for an electric axle drive used to start up a winding spool, which can be detached after the run-up and after the start of the winding-up process by a drive roller drive which is synchronized in peripheral speed and which becomes effective as a result of the increasing winding diameter.
- Circumferential drives with drive rollers are very often used to drive the winding spools in the chemical fiber industry, since this makes it relatively easy to maintain constant thread take-off speeds.
- these circumferential drives are not always able to move the empty winding spool from standstill to nominal speed in a relatively short time. Additional axle drives are therefore used, which are switched off again after the drive roller drive takes effect.
- the change in power of the start-up motor caused by the drive roller motor becoming effective can be used as a criterion for the switch-off command.
- the problem arises here that the power (torque) at which the command would have to be given depends on numerous technological parameters, such as, for example, B. the number of threads to be wound up simultaneously, the thread thickness, the thread speed and the air gap between the bobbin and the drive roller is dependent.
- the object of the present invention is to design the arrangement of the type mentioned at the outset such that the criterion for the switch-off command is automatically adapted to the different parameters.
- This object is achieved according to the invention in that after the run-up and start of the winding process and before the drive roller drive takes effect, a measured value proportional to the torque of the axle drive can be stored and the switch-off command can be triggered when the measured instantaneous value for the moment after the drive roller drive takes effect has the stored value by a predetermined amount.
- the value resulting after the run-up and the thread lying on the bobbin is stored as the switch-off setpoint. This value takes account of the current conditions.
- the storage command is advantageously only issued shortly after the start of the winding process.
- the conditions for the switch-off command are advantageously checked for presence only after a predetermined time.
- the arrangement can be realized particularly simply by taking the actual current value after the thread is placed in a memory amplifier, the output signal of which is compared with the instantaneous value of the current in a comparator, which in turn triggers the switch-off command when the measured value matches the stored setpoint.
- the coil is hereby at nominal speed - which, for. B. can correspond to a peripheral speed of 4000 meters per minute -, ramped up.
- the z. B. is withdrawn from an extruder, not shown, placed on the winding spool 1.
- the motor current J which is proportional to the torque of the motor 4 increases to the static value J a after short-term dynamic processes have subsided.
- This measured value is fed to a memory amplifier 91 via a filter 92.
- the application device 3 generates a signal which, via the contact 31 and a delay element 99 with the duration t v1, disconnects the memory amplifier 91 from the actual current value J at the time t a by opening the switch 911.
- the current actual value present at this time which is proportional to the torque, is retained in the memory amplifier 91.
- the drive 5 is also a synchronous motor, which is fed from the converter 7. If the gap s is filled at the time t 2 , there is circumferential contact between the winding spool and the drive roller. Since the peripheral speeds of the winding bobbin and the drive roller are well synchronized, the motor 4 is first relieved by the motor 5, so that the measured current J of the motor 4 decreases in accordance with FIG. With increasing winding diameter, the peripheral speed of the winding drive increases, so that the motor 5 from the motor 4 is dragged along; the current J of the motor 4 increases again.
- this current again reaches the stored output value J a at time t 3 .
- this value is exceeded by an experimentally determined adjustable amount AJ and the triggering command is thus formed.
- this is done in that the output of the memory amplifier 91 and the instantaneous instantaneous value J of the motor 4 taken from the filter 92 via line 93 are connected to a comparator 94 which emits a signal if the two values match.
- the adjustable value AJ can be taken into account by a corresponding design of the comparator 94 or the memory amplifier 91.
- the output signal of the comparator 94 is linked to the output signal of a delay element 98, which is also triggered when the switch 31 closes and which fulfills a further AND condition on a logic element 95 after the time t v2 so that no switch-off commands which are too early and thus incorrect are triggered .
- the signal caused by the closing of the switch 31 is applied to this link 95. If all logic conditions are met, the signaling relay 96 sends the switch-off command A to the converter 6 via line 97 and the motor 4 is mechanically separated from the winding coil 1 by the coupling 41.
