The Challenge: Demand Growth Led to Persistent End-of-Line Bottlenecks and Unreliability
A leading third-party logistics (3PL) provider specializing in the distribution of manufactured products with a core focus on repackaging and co-packing came to PACKPRO with a business growth challenge. Operating as a 3PL means performance is measured both internally and against the expectations of the manufacturers and brands they serve. This makes line reliability and throughput consistency business-critical. As production demands increased for the 3PL, the limitations of their existing process became harder to absorb. The operation was experiencing unreliable case erecting and case sealing, and manual product loading and end-of-line palletizing had become a persistent bottleneck. The downstream effects were real and compounding. Reduced line efficiency and inconsistent reliability meant the 3PL regularly needed to run longer production cycles just to fulfill standard orders. This consumed time, labour, and capacity that could have been directed elsewhere. For a co-packing operation where fulfilling client commitments on time is the core value proposition, these inefficiencies were both an operational and a competitive challenge.
The Solution: A Customized Integrated System Implementation
PACKPRO took a diagnostic-first approach to the customer’s challenge. Sales, engineering, and service teams worked directly alongside the customer’s production, operations, engineering, and maintenance teams to map the process. This helped identify exactly where the bottlenecks were and when they happened, compared to what the ideal output and process needed to achieve. With a clear picture of the requirements, PACKPRO engaged preferred equipment suppliers and developed a fully integrated, turnkey end-of-line system tailored to the customer’s operation. The scope of implementation included:
- Semi-Automatic Case Erector — bringing consistency and speed to case forming at the start of the line
- Automatic Top and Bottom Case Sealer — eliminating the variability and reliability issues that had been affecting downstream flow
- Automatic Conveyance — connecting the line and enabling controlled product movement between stations
- Automatic Robot Palletizing — replacing the manual palletizing process with a repeatable, high-throughput automated solution
- System Controls — providing unified control over line speed and throughput across all integrated components
From system design and development through to installation, operator training, and live deployment, PACKPRO’s engineering and service teams were embedded throughout the project. The upfront process review and planning paid off: the installation and transition proceeded smoothly, with only minor refinements needed along the way. A key area of learning through commissioning was optimizing the collaborative robot’s integration with the conveyor control system to dial in line speed and throughput performance.
The Results: Measurable Operational Impact and Future Roadmap
Since the system went live, the customer has seen improvements across the key areas that were driving the original challenge:
- Increased line efficiency — with automated case erecting, sealing, and palletizing running consistently, the line performs more reliably and requires less intervention to maintain throughput
- Reduced headcount at end-of-line — automation has taken on the manual palletizing work, freeing up personnel for other tasks
- Improved equipment reliability — the integrated, controlled system has reduced the unpredictability that previously forced longer production runs
The impact on workers has also been notable. Manual palletizing is physically demanding and repetitive, contributing to fatigue and ergonomic strain over time. With the robot palletizer handling that work, the customer has meaningfully improved day-to-day working conditions for their team. Perhaps the strongest signal of the project’s success is what the customer is planning next. With quantifiable throughput improvements now confirmed, they are actively looking to bring the same automation approach to additional lines as part of their long-term operational strategy.
