Automatic Belt Influence Compensation (BIC):
Not even the best of conveyor belts is perfectly even;
particulary in welding points, the belt will be heavier
and stiffer. The figure above shows the relations over
one belt circuit in exaggerated fashion.
Therefore, a high accuracy can normally be ensured
only over entire belt circuits, i.e. over the mean value.
INTECONT is able to acquire and correct this
influence with the use of a belt circuit sensor and a
metal belt mark.
This considerably increases the scale’s short-term
accuracy.
To enable variations to be considered during
operation, the belt influence is continuously
measured. The compensation adaptively follows up,
also if material is fed.
Measurement at the point of discharge (CPD):
For constructional reasons, the weighing platform is
not directly located at the point of material discharge.
Therefore, if belt load varies, the feed rate measuring
result does not exactly correspond to the current feed
rate at the point of discharge.
A special speed-dependent delay elements shifts the
measurement to the discharge point.
To do so, no special load transducers are required;
however, the additional use of the automatic belt
influence compensation is reasonable.
Batching:
In batching mode, a preselected material amount is
fed. When batch setpoint is reached, batching stops.
Batching can be controlled via conveyor belt drive or
material prefeeder.
Control via belt drive:
In this mode, the conveyor belt is still fully loaded after
complete batch.
