High-speed packaging line control retrofit
Line master PLC implementation across conveyors, labellers, checkweighers and palletising, including zone-based diagnostics and coordinated recovery logic.
Industry · 03
Packaging Line Automation (PackML)
Metromotion Controls automates packaging lines across Melbourne and Victoria, integrating fillers, sealers, labellers, conveyors, inspection systems, palletising and packaging OEE data into one line control strategy.
Packaging lines need reliable states, fast changeovers and clear fault recovery. Metromotion Controls integrates fillers, sealers, labellers, conveyors, inspection systems, case packing, pallet handling, line control systems and packaging OEE data to improve visibility of line losses.
Sector Challenges
Problems we solve
01
Micro-stops and cascading faults on high-speed lines
Small interruptions can quickly escalate across infeed, process and end-of-line zones. Teams need clear fault hierarchy and buffer-aware control to stabilise throughput.
02
Frequent SKU and format changeovers
Short runs require rapid, repeatable setup changes across machine parameters, label data and inspection limits. Manual setup increases variation and startup scrap.
03
Vision and print verification integration
Inspection and coding systems are often bolted on rather than integrated. This can lead to inconsistent reject handling and poor root-cause visibility.
04
Limited OEE signal quality
Many lines collect runtime states without standard reason coding or context. This limits improvement programs because losses are not measured consistently.
Our Approach
How we deliver
We structure packaging line control around equipment states, coordinated handshakes and accumulation logic that protects throughput under variable downstream demand. Line control includes deterministic start, stop and recovery sequences with clear operator guidance.
For changeovers, we deploy recipe parameter packs across PLC, HMI, vision and printer systems, with role-based permissions and confirmation workflows. This reduces setup errors and improves first-pass quality after product transitions.
Vision and labelling systems are integrated into core line control rather than isolated at machine level. Reject confirmation, recirculation strategies, ejection timing and rework capture are implemented to support compliance and reduce unexplained losses.
We implement OEE architectures with ISA-95 aligned reason trees, standardised downtime events and contextual production counts. Data is available in real time and historically, so operations teams can target the highest-impact throughput and uptime gains by verified loss category rather than by assumption.
Typical Work

Packaging OEE and performance dashboard rollout
Plant-wide data model with runtime states, reason coding governance and management dashboards for shift and weekly performance review.
Platforms
Technology we work with
Packaging plants benefit from controls that can integrate OEM machine controllers, third-party inspection equipment and enterprise reporting tools without compromising line speed.
01
Automation platforms: Rockwell Logix, Siemens TIA, Beckhoff and Schneider depending on line architecture.
02
Inspection and coding: Cognex, Keyence, SICK, Markem-Imaje, Domino and Videojet integrations.
03
Robotics and motion: ABB, FANUC, KUKA and servo control systems for palletising and pick-and-place operations.
04
Data standards: OPC UA, PackML concepts, MQTT gateways and SQL-based event storage for OEE.
AS/NZS 4024 and ISO 13849 for machinery safety implementation.
GS1-aligned labelling and traceability data structures where required.
Site quality requirements for print verification and reject accountability.
Structured FAT/SAT documentation for packaging line acceptance.
Common Questions
Frequently asked
Can you integrate multiple OEM machines into one line control strategy?
Yes. We commonly implement a line master layer that coordinates machine states and handshakes while preserving OEM controller responsibilities. This improves startup behaviour, reduces fault propagation and gives operators one consistent view of line status.
How do you reduce changeover time on packaging lines?
We standardise product recipes across all relevant subsystems and include guided setup workflows on HMIs. Combined with validation checks and role-based access, this reduces manual parameter entry and shortens time to stable production.
What level of OEE reporting can be delivered?
We provide real-time dashboards, shift summaries and historical analysis by line, machine and reason code. The architecture supports both daily operational decisions and longer-term loss elimination programs with verifiable data quality.
Can you deliver conveyor automation and packaging OEE systems?
Yes. We integrate conveyors, line control, machine states, production counts and downtime reasons so packaging OEE systems reflect what is happening across the whole line.
