We recently undertook a comprehensive Automation Upgrade for a customer, enhancing their existing Schafer & Flottmann Case Packing machine originally built in 2008. The goal was to modernise the machine’s control hardware while maintaining operational continuity, as relocating the machine from the factory during the upgrade was not feasible.
The upgrade involved a complete overhaul of the control panel, replacing outdated Siemens components with advanced Rockwell Automation hardware. This conversion included installing a new gearplate that fits within the existing cabinet. Key components of the upgrade included:
- Drives Replacement: The aging Rexroth drives were substituted with modern Kinetix 5700 drives, coupled with Rockwell VPL servo motors. This alignment with newer technology improves efficiency and performance.
- PLC Upgrade: The Siemens PLC was replaced with a Rockwell CompactLogix processor (model 5069-L330ERM) to ensure compatibility with Westland’s newer SFS machine.
- Safety Improvements: A Sick Flexisoft Safety Controller was integrated to enhance operational safety protocols.
- User Interface Enhancement: A new PanelView Plus 7, featuring a 10” HMI, was installed, providing an updated and user-friendly interface for machine operators.
- Component Upgrades: Five Rockwell VPL servo motors and corresponding cables were installed, along with five new gearboxes to accommodate the new motor specifications. A servo transfer unit replaced an outdated cylinder, improving the machine’s capabilities.
- Valve System Modernisation: The old Festo Valve Profibus banks were upgraded to SMC Ethernet valve banks, enabling faster, more reliable communication.
The project encapsulated extensive mechanical and electrical design tasks, including the creation of updated electrical drawings and automation design that mirrored the current setup of the other SFS machine in operation.

We handled all electrical wiring for the new gearplate at their facility and managed the mechanical assembly of the servo transfer unit. The final stages of the project were executed onsite at the customer’s factory, involving mechanical fitting and electrical wiring of the new hardware, followed by thorough automation testing to validate performance.
This meticulous upgrade not only revitalised aging machinery but also aligned it with the customer’s operational standards, thereby fostering greater productivity and reliability in its production processes.
