Abstract: A conveyor system and the operation of a conveyor system will convey articles such as baggage at airports. A buffer arrangement is provided for storing and pre-sorting at least a part of the article-flow through the system. A conveyor system for conveying and sorting articles for a number of different destinations may be operated with a much lower number of stations for discharging the articles if the possibility of pre-sorting and temporarily storing the articles exists within the system. In particular, a storage rack can be provided for storing articles and the conveyor system comprising such a storage rack.
