Abstract:
Conveyor weighing unit for weighing objects transported along a conveyor, comprising:a frame, a conveyor belt forming an endless loop, a first guiding unit defining a first conveying direction extending in-between the top sides of two opposite arranged rollers, a weighing device being a part of the first guiding unit, said belt being driven in a revolving manner by a driving unit and transported over said weighing device in said conveying direction, said weighing device including: two or more side by side, in said conveying direction arranged weighing platforms, each platform having a pre-defined platform length, each weighing platform continuously weighing the conveyor belt section placed thereover and the object transported thereon, wherein one or more adjacent arranged weighing platforms constitutes at each time a weighing unit having a total platform length equal or greater than the object length to be weighed, said weighing platforms being operatively connected to a data processing unit, said data processing unit receiving and processing data from said weighing platforms, and based thereupon, the weight of the object is determined and an accordingly appropriate number of adjacent platforms selected, having an added length at least equal to the length of the object to be weighed and thereby enabling minimal spacing between adjacent objects and maximum operational capacity.
