A weighing conveyor system, a checkweigher, and a method for weighing conveyed objects with a checkweigher comprising LIM-driven rollers positioned in a conveying line and position sensors for determining the objects' weights from the motion of the objects across the rollers. The LIM drives the rollers with a constant torque. The acceleration of an object driven by the rollers is inversely proportional to the object's weight. So an object's weight can be determined by the effect of the rollers on its motion. |
