Control system for conveyor technology for a container washing system

Staedler Automation AG designed, developed and commissioned the control system for this plant of a major distributor.

The plant consists of two lines with a capacity of 1500 containers/h each.

Different types of containers are unstacked and then transported to the washing machine by the conveyor system. After the washing machine, the containers are taken over, pre-stacked and prepared for the robot.

The existing S5 control system in the robot cell was integrated into the main control system, which is taken over by a Siemens safety PLC. This is connected to the servo inverters and IO modules via Profinet. All safety components are read in and controlled directly by the PLC.
