Apparatus and method for weighing moving objects |
摘要 |
Apparatus and method for measuring the weight of an object such as a letter, magazine or parcel, while the object is in motion, without using a weighing scale. The apparatus and method disclosed make use of moving, preferably vertically-oriented transport belts driven by a constant velocity, closed-loop feedback system which includes an electric motor. An object to be weighed is engaged and lifted upwards by the moving belts, increasing the load on the motor as a function of the weight of the object. The increased motor current evoked by the lifted object can be processed to extract the object's weight.
