Nord in Audi
Nord Gearmotors in Audi. A series of geared motors from Nord has been installed to drive a chain conveyor belt system in Audi’s advanced production facility in Ingolstadt, Germany, where the doors for the Audi A4 and A5 are produced.
Few people are visible in Audi’s large and highly automated production facility. Instead, large robot arms reach into special containers and remove sheet metal parts. Further along the production line, sparks fly where the welding robots do their work. The article being produced slowly takes shape: doors for Audi’s A4 and A5 models.
The parts are routed along a chain conveyor belt system powered by Nord drives. This branches into loading and unloading sections, which convey the vehicle component containers from work station to station.
The system is equipped with lifting equipment, transport carriages and elevating platforms. The complete system is driven by Nord components, mainly bevel gearboxes.
The chain conveyor belt and the rotary units for direction changes are controlled by almost 400 of Nord’s decentralised field I/O modules. The motor is connected to the field I/O module using Harting connectors, so that it – and the inverter drive – can be replaced quickly if necessary.
In addition, the system also uses decentralised reverse starters, which can be controlled via the outputs of the field I/O module. The reverse starters take over functions such as the centring of the containers for position-accurate transfer to the robots. They move the elevating platforms in the transfer section to the forklifts and lock the load in lift equipment.
The conveyor belt system is equipped with seven lift stations, which are controlled by frequency inverter drives from Nord’s SK 700E range. In lift stations that operate over more than two levels, the inverter is equipped with positioning control which takes over the dynamic positioning.
