Figure 2-1 Example of an electronic cam control
Example: Press control
The automation of an eccentric press using a cam controller is another typical application.
Press operation is based on a rotary motion, i.e. the rotary axis moves by 360 degrees, and
then starts the next cycle at zero.
Typical tasks of an electronic cam controller:
● Switching a lubricating system on and off
● Enabling material feed and discharge (for example, gripper control)
● Stopping the press at the "upper dead center"
Example: Packaging unit
Preserves are packed on an automatic rotary turntable. The electronic cam controller
triggers actions at specific angular positions:
● Inserting and unfolding the cardboard box on the automatic rotary turntable
● Filling the preserves into the cardboard boxes
● Closing the cardboard boxes
● Transfer of the cardboard boxes to a conveyor
