5.1.2 Adjusting the required running behavior or the synchronism of the
linear feeder track
In order to achieve synchronism of the linear feeder track, the spring angle must be adjusted
the same as the gravity center angle. The gravity center angle is determined by the position
of the two gravity centers of oscillating and counterweight.
Example with a gravity center angle of 12.5 °
Spring angle equals gravity center angle
The force direction of the springs is initiated exactly on the gravity center of the vibrator.
Consequence: The height amplitude is the same at the feeding and at the discharge side.
Spring angle larger than the gravity center angle
The force direction of the springs is initiated before the gravity center of the vibrator.
Consequence: The height amplitude is higher in the feeding area than in the discharge area.
