Storage Order Picking Handling & Automation 03 Case Study 026 Machinery BUFFER STORE WITH AN INNOVATIVE FIRE-EXTINGUISHING SYSTEM The Customer Knorr-Bremse is the world’s leading manufacturer of braking systems for rail and commercial vehicles. As a technological pacesetter the company has been promoting the development, production, distribution and servicing of modern braking systems for more than 100 years. Knorr-Bremse has more than 20,000 employees worldwide; around 3,800 of them work in the company’s four different locations in Germany. Apart from the company headquarters in Munich and the historic company site in Berlin Knorr-Bremse has also production facilities in Bavaria and a development centre in Baden-Württemberg.

Each assembly worker had access to the entire stock which lead to large numbers of misplaced items and incorrect stock levels. Knorr-Bremse had therefore decided to pool the buffers for the assembly components at one central location. The company also needed an effective fire-extinguishing system that would protect the stored parts. 2 Solution In 8 Shuttle XP units, more than 210,000 parts are now stored on a footprint of only 84 m² mostly in plastic bins. Order pickers place the parts on trolleys and transport them to the assembly sites. In this system, the innovative Kardex Remstar Fire Solution came into play. In the event of a fire, residue-free inert gas is used to extinguish the fire. The novelty about the solution presented by Kardex Remstar: along the entire height of the Shuttle units, nozzles distributed at a distance of 5 cm are ready to inject the gas with only 4 bar directly into the storage units. Gases are distributed over the whole system very fast, the oxygen concentration in the air is quickly reduced to below 8.8 percent, and a fire is extinguished in the shortest possible time. As a result of the low pressure, there is no damage to the stored components. However, a fire-extinguishing system is only as good as its fire warning system: at Knorr-Bremse plastic tubes continuously suck in air from the Shuttle interior and check the air for traces of smoke particles. If a limit value is exceeded, the fire warning signal is issued. 4 Advantages at a glance 3 – Substantial space savings: 1,000 m² of storage space on a footprint of only 84 m² Process description We would be delighted to explain the different processes – Lower error rates during order picking in detail in a personal consul- – Reliable fire warning system with fast detec- tation. tion of smoke particles in Shuttle interior – No damage to Shuttle or stored goods in the event of a fire 5 Scope of delivery – 8 x Shuttle XP 500 (W x D x H: 3,050 x 864 x 7,350 mm), installed in two 4-unit blocks – Gas extinguishing system with special fire alarm system – Main discharge: 18 gas bottles inergen gas – Discharge to maintain concentration: 16 gas bottles of nitrogen Further Information: www.kardex-remstar.com
