Manual or automated format adjustment

Numerous possibilities

Still not sure how your lead screw actuator should be driven? We present you with various options:

Two manual drives, for example with position indicator and hand wheel
One manual and one electric drive
Two electric drives, e.g. with stepper motor

You can discover the respective advantages on the following slides.

Manual format adjustment

More sophisticated format adjustments are realized with torsion-resistant linear axes. On the one hand, these tolerate Higher forces and, thanks to the hand wheel and position indicator Precise fine adjustment of a desired control value. They are also quickly configured and implemented in the system. Since the operation of manual positioning systems without an actuator can still be time-consuming, this system is only worthwhile if format adjustments in the machine occur less frequently.

Automated format adjustment

Are Format adjustments regularly recurring and in many places In order to fulfil the requirements of the packaging machine, positioning systems with actuator connections become indispensable. Through the Time saving can quickly amortize the higher costs compared to manual systems. With the optional addition of a motor control unit Position several adjustment units synchronously. This also helps to avoid errors.
