Abstract

A fast, dynamic scale has a weighing unit formed by a weighing cell and a transport mechanism with a first motor to drive the transport mechanism. The transport mechanism) is arranged with the motor on the weighing cell, so the weighing cell is loaded with a preliminary load. A first sensor is located at the beginning of the weighing unit. This first sensor emits a first signal to a control unit to start the weighing process for a cargo piece B. A second sensor emits a second signal to the control unit that thereupon generates a communication that a cargo piece Bn following the cargo piece B can be supplied. A weighing unit with a shortened effective length for the weighing is provided. The shortened length allows the interval between successive cargo pieces to be correspondingly shortened. A switchable extraction device is arranged after the weighing unit in the transport direction. The control unit controls the cargo piece transport by means of a third motor of the extraction device and to control the extraction device depending on the length of the cargo piece and on the termination of the weight determination as a result of the weighing, with the extraction device being switche…
