Siemens Automates high-bay warehouse at Audi

October 22, 2013 - At the Audi factory in Győr, Hungary, Siemens constructed a fully automated high-bay warehouse that acts as a central body buffer and occupies a key position within the production logistics of the plant. Equipped with Siemens drives technology, it is extremely energy-efficient in operation.

Siemens developed the controller of the storage and retrieval machines and the conveyor system for the body buffer on the basis of its Simatic S7 controllers. The bodies are conveyed by means of 350 Siemens electric motors together with frequency converters. The integrated drive system is equipped with energy-saving motors and is capable of recovering and storing kinetic energy. This means that it captures braking energy, stores it and makes it available to other drives. The result: fewer undesirable network perturbations and lower power consumption. In addition, Siemens has set up an RFID system that uniquely identifies each body stored in the body buffer and on its way through production.

The solution created by Siemens is centrally located in the production at the Audi plant in Győr and acts as a hub between the individual production stations. By the time they reach the final assembly, all bodies have passed through the high-bay warehouse twice – once as unpainted and once as painted bodies. With the aid of the central body buffer, Audi can optimize its production, despite the wide variety of models and versions, by returning the bodies each time to the appropriate sequence for the individual stages of production. This sequencing of bodies results in greater flexibility and higher productivity at the Audi plant.

AUDI AG is one of the fastest growing car manufacturers in the world. The establishment of AUDI HUNGARIA MOTOR Kft. in Győr in 1993 was the starting signal for the construction of this state-of-the-art factory. Since then, the company has advanced to become one of the largest exporters in Hungary and one of the largest companies overall in terms of turnover. In 2012 Audi Hungaria produced a total of 1,648,030 engines and 38,541 cars.
