You keep saying that. It would not be simple or cheap. At the moment
you just need a crude set of rollers and bearings, and a sufficiently
powerful motor to overcome limiting friction at maximum torque. You
would need some combination of better bearings for the belt rollers,
more precision and rigidity of the whole conveyor structure, a much
larger motor with either a variable frequency inverter or a continuously
variable gearbox. And a control system to replace the current on/off
switch in the mains supply. If you don't believe me, try and make one
yourself.
All you need is a sort of visvoius clutch, or possibly a flywheel, to
smooth out jerkiness. And then move the sensor a bit upstream


BUT how will that improve profits?
