Abstract

A transport system may include at least two conveyor sections and at least three cars that are moved individually in a cyclical operation. Each car may pass through a first conveyor section starting from a first start position and subsequently pass through a second conveyor section back to the first start position. At least one stopping point may be provided at least along a conveyor section, and one or more subsequent stopping points may respectively be assigned to a block. Travel of the cars may be controlled such that the cars successively approach a respective previously-specified block, and an equal cycle time is predefined for every car to pass through the first and second conveyor sections. A method for operating a transport system in this manner is also disclosed.
