The empty roll containers are delivered and are manually unloaded. Then they are placed onto the conveyor system and are fully automatically stored into the buffer zone.
The 38 buffer lines, which have together an impressive length of 2 km, are connected to the two shuttle cars, which are situated at the both ends of the buffer zone. Total the buffer zone has place for 3‘420 roll containers. One shuttle car is able to handle 900 roll containers per hour.
With this buffer zone the commissioning hall remains free from shifting traffic and the valuable handling space can be used efficiently. On demand the buffer will forward the roll containers in the right picking and delivery area.
