Vibration conveyor drives are magnetically propelled two-mass-oscillators with
The useful load and the leaf spring elements form a resonance system with a narrow band, the mechanical resonance frequency. Any change in the useful load or the leaf spring elements varies this resonance frequency.
The stable operation of a conventional vibration conveyor has tight operational limits, because
Any change of the useful load (e.g. a changed trough load) enforces an expensive adjustment (e.g. by installing add-on weights or exchanging the leaf spring elements). Any inadequate adjustment results in
Another disadvantage of the conventional technology: the flow rate is non-linear to the excitation voltage (corresponding to an exponential function with a very large gradient).
The company ARBO Systems now completely breaks with this tradition. The new vibration conveyor drive
Note: The vibration conveyor allows for dual- or multiple-drive arrangements, in which one tachometer generator usually is sufficient.
The linear tachometer generator
Note: The linear tachometer generator is ideal for retrofitting conventional vibration conveyors. They will considerably improve.
The frequency control loop synchronizes the drive frequency to the oscillating system (it is not the conventional way, where the resonance frequency has to be adjusted)
