Abstract

A dynamic scale has multiple weighing units, each equipped with a weighing cell and a weighing pan, the weighing pan lying in an upper plane and the weighing cell between a lower plane spaced from the upper plane in the direction of gravity. A transport device has a motor encoder and sensors, with the encoder and sensors being electrically connected with the inputs of a control unit. The multiple weighing units are serially adjacent in a transport path, with simultaneous cascaded arrangement of the weighing cells in the direction of gravity. The control unit simultaneously starts the weighing processes in all weighing cells in a dynamic weighing mode and controls a transport motor depending on signals of the sensors and the encoder and controls the dynamic scale depending on signals from the weighing cells.
