Canline and NPB have unveiled a joint breakthrough: Dynamic Hopper Technology. Aimed squarely at the industry’s most persistent bottleneck—the stacking process—the solution promises to significantly boost conveying uptime and robustness.

Traditionally, vacuum hoppers and liner discharges have been the “weakest link” in high-performance lines. Even minor variations in end behavior or spacing can trigger jams and costly stoppages, a problem only magnified as production speeds climb.

The new patent-pending Dynamic Hopper takes a “forgiving” approach. Rather than requiring absolute precision, its geometry and operating principles are designed to absorb process disturbances and material variations.

Performance Highlights

After six months of field production, the data confirms a substantial leap in efficiency compared to traditional vacuum hoppers:

Engineering for the Future

While current high-speed lines typically operate around 2,600 ends per minute (EPM), the Dynamic Hopper is built for the next generation of manufacturing. The technology is already rated for speeds up to 3,500 EPM, ensuring that today’s investment remains relevant as industry demands evolve.

“The availability and efficiency of end conveying are ultimately defined by the system’s ability to stack ends reliably,” says Magnus Wigenstedt, Director of Sales and Technical Development at NPB. “By rethinking the weakest link in the chain, we have developed a solution that directly translates improved liner discharge performance into higher overall line uptime.”

A Smarter Design

The system achieves its results through three key pillars:

• Revised Downstacker Geometry: Optimised to handle ends more naturally.
• Controlled Vacuum Levels: Precision suction that adapts to conditions.
• Variable Conveying Speed: Automatically compensates for misalignments, reducing the need for constant operator intervention.

Scalability and Retrofits

The collaboration combines Canline’s specialised conveying expertise with NPB’s automation mastery. The technology is being launched initially for liner discharge conveying under the Liner Discharge Conveyor DH name.

Crucially for existing producers, the solution is not limited to new builds. The Dynamic Hopper LD is available as a retrofit, allowing manufacturers to upgrade existing lines and increase capacity without major layout overhauls.

“This technology sets a new standard for conveying uptime,” adds Eric Reinders, Sales Manager at Canline. The rollout is expected to expand soon to include Dynamic Hopper solutions for synchronizers and other critical end-line applications.
