Smart Conveyance Systems Advance Packaging Automation

Consumer packaged goods (CPG) manufacturers operate under constant pressure to adapt to fluctuating market demands and product variations while maximizing throughput. To address these demands, Bosch Rexroth exhibits its comprehensive factory automation portfolio at Booth #S-1654 during PACK EXPO 2026 in Chicago, Illinois, scheduled from October 18 to October 21, 2026. The technical showcase focuses on smart transport systems, modular conveyor architectures, and decentralized drive electronics designed to streamline packaging workflows.

High-Speed Linear Motion and Modular Conveyance
Material handling forms the backbone of packaging efficiency, requiring precise synchronization between product flow and secondary operations. Bosch Rexroth addresses high-density routing and mass transport through its VarioFlow and ctrlX FLOWHS product lines.

The VarioFlow plus modular conveyor system is demonstrated via a spiraled configuration incorporating a downward slope leading directly to a buffer table. This layout highlights vertical space optimization and active accumulation management. Complementing this is the VarioFlow belt conveyor, which utilizes a fine-meshed, near-closed flat surface chain designed explicitly for bulk or unstable film-packaged items, such as small sealed-edge pouches. The modular architecture permits variable belt widths and custom track layouts to match existing factory footprints.

For integrated robotic handling, a VarioFlow plus unit operates in tandem with Bosch Rexroth aluminum structural framing and a Kassow Robots KR 1824 collaborative robot (cobot), illustrating the ongoing transition toward flexible human-robot coexistence in packaging cells.

At the upper performance tier, the smart linear transport system ctrlX FLOWHS delivers independent mover control with an acceleration capacity of up to 10 G and a maximum velocity of 5 m/s. Engineered with a minimal product spacing of 40 mm and small individual movers, the system allows dense product accumulation and rapid positioning within confined machinery modules.

Decentralized Servo Architecture and Control Integration
Traditional packaging lines rely heavily on centralized control cabinets that consume valuable floor space and complicate cable routing. Bosch Rexroth counters this limitation with the ctrlX AUTOMATION ecosystem and the cabinet-free ctrlX DRIVE system rated at IP65 and IP67 protection classes.

By mounting servo drives directly on or near the machine module, the IP65/IP67 ctrlX DRIVE eliminates the need for a traditional central control cabinet. This decentralization reduces wiring overhead, simplifies machine modularity, and scales across diverse multi-axis configurations. The architecture maintains open communication standards and high real-time servo performance, enabling CPG machine builders to design compact, easily reconfigurable packaging lines.

The ctrlX FLOWHS high-speed linear transport system competes in the intelligent track and planar mover segment against established multi-mover solutions such as the Beckhoff XTS (Extended Transport System) and Rockwell Automation Independent Cart Technology (ICT). While traditional loop conveyors rely on mechanical chain friction and fixed pitches, electromagnetic track systems like ctrlX FLOWHS use individual software-controlled movers to eliminate mechanical wear points and allow independent motion profiles per carrier.

In the decentralized drive category, cabinet-free servo solutions such as Bosch Rexroth’s ctrlX DRIVE IP65/IP67 and its predecessor IndraDrive Mi compete with modular decentralized drives like the Siemens SINAMICS G220 or Beckhoff AMP8000 distributed servo system. The primary engineering trade-off centers on thermal dissipation and ingress protection: decentralized IP65/IP67 units must sustain continuous root-mean-square (RMS) torque delivery in ambient plant environments without the active air-conditioning found inside sealed NEMA/IP54 floor-standing cabinets. Bosch Rexroth achieves this through direct metal-to-frame thermal coupling and localized electronic protection, reducing cabinet footprint requirements by up to 100% for designated servo axes.
