Abstract

A conveyor system for transported goods which are transported with a preset transport speed and method for operating the conveyor system are described. The individual conveyers of the system are driven by asynchronous motors. Sensors associated with the conveyors measure the actual transport speed of the transported goods on conveyors to determine the dependence of the actual transport speed on the load, such as the weight of the transported goods. A controller adjusts the speed of the conveyors based on the signals received from the sensors.
