Reliability of evaluations for the choice of system solutions at the example of automated order-picking systems for bagged goods

There is a steadily increasing pressure on cost-savings and productivity growth in sectors of order-picking such that the wish for rationalization by automation is rising. Special problems are faced trying to automatize handling operations of order-picking articles packed in bags. The mechanical properties of the objects and their hard-to-predict shape and position represent obstacles and are complicating handling operations. A systematic approach in system design is required. This article deals with the properties of such products under aspects of difficulties arising in automated handling and points out a useful system development methodology.

Novel calculation method for chain conveyor systems

Sidexflexing plastic chains are used increasingly in material handling due to their highly flexible conveying design and layout options. These systems are often equipped with so called modular belts. Due to their specific force transmission, detailed calculation methods are not yet available. In the following, a generally valid calculation approach is derived and its difference to existing solutions shown by examples.
