The opportunity to determine and evaluate the environmental sustainability of the “intralogistics” systems is the main common ecological aim of industry concerns, research institutes and associations. Although a standardized approach and transparency within the assessment process is essential. Based on the simulation models for almost every technological component, that are developed, validated, based on parameter and analyzed by the IFL, either the part systems or the coherent processes are able to be energetic quantified.

Those simulation models are for example rack feeder, continuous conveyor like roll-, belt- or chain conveyor or electric monorail conveyor, sorting system or driverless transportation systems.

Currently an ecological key figure model to evaluate the ecological efficiency is in process that enables a comparison to different “intralogistics” systems. The definition of “intralogistics” effort provides a benchmark for that. Possibly this benchmark should cover an abundance of requirements for the logistic system e.g. the capacity of the systems or the transported amount. Likewise the dimension of the conveyor unit, capacity utilization or as well the order structure or driving- and operation strategies shouldn’t be ignored. This and other benchmarks are a fundamental basis for the composition of “intralogistics” effort.

How efficient is your intralogistics process?

If the society shows more ecological consciousness and there are more strict guidelines given, the significance of energetic efficient “intralogistics” processes would rise. The processes would become a differentiation factor between the companies and at the same time would reduce the operating costs because of the saving of energy. The environmental compatability between different “intralogistics” processes can be compared by the key figure model that was developed by us.

Today the use of fully automatic single-mast stacker cranes (RBG) is common in automated high bay systems. The height of stroke of over 40 meters and the lifting capacity of over 1 ton is not unusual. To rise the efficiency of the storage, it is required to increase the throughput quantity that is achieved through an increasing dynamic of the RBGs. Through that there is a growing risk of a vibrational response of the systems “RGB”. Consequences are long waiting periods to swing out of the system and increasing demand of devices. Applied methods to eliminate or reduce the swinging as well the startup and braking with certain speedup profiles and a possibly high buffer offers in many cases no pleasant result. The application of a second impulse at the mast cap is in the most cases economically not realizable and brings new dynamic problems. The reason for that is the force transmission in the storage rack because it would require a very complex storage shelf construction.  

The state control of the RBG-drive that was developed by the IFL is not yet established industrial because of the required sensor- and control effort. With the help of modern engine control it is the aim of the project to operate the RBG-drive in dependence of the system status. Multiple parameter of the engine control are known.
