Conveyor technology for automated machining centres

Project description

A well-known automotive supplier from Austria expanded its production to include a fully automated machining area. Our engineering technology team provided the EI&C planning and other electrical service components.

Roller conveyors, paternoster lifts and automatic handling machines transport the workpieces between the machining centres, such as washing, drying, rough and fine machining. Automatic handling machines rotate and move the workpieces to the optimal positions for machining and quality assurance, and then back into the transport position.

By means of data tracking and identification, the workpieces can be continuously followed and assigned to the appropriate work areas and systems according to product type and batch. The system is monitored and controlled by a central S7-400 PLC. The IPC panels at information points in the production hall supplement the central visualisation in the control room. The eighteen machining stations are each equipped with an independent S7-300 PLC and communicate with the central PLC via Profibus.

System visualisation and coupling to the production control system is achieved via Industrial Ethernet.
