Krones has introduced Robobox SynFlow, a modular system that uses robotics to distribute containers into packer lanes, marking what it describes as the first use of robotic technology for container distribution.
The system, developed in Krones HQ in Neutraubling and launched on 5 May 2026, applies a tripod robot to group incoming containers and direct them into designated lanes before packing. It replaces conventional guide systems that operate on fixed patterns, which can result in uneven lane filling and gaps in container flow, sometimes requiring manual intervention during production.
Krones said the system uses “intelligent robotics” to monitor container volumes in real time and adjust distribution dynamically. This allows the system to “close gaps” and maintain a consistent supply of containers to the packer.
The Robobox SynFlow is available in two configurations. The smaller version uses a single tripod robot and can handle up to 55,000 containers per hour, intended for a single container flow into the packer. The larger version uses two tripod robots and can process up to 105,000 containers per hour, suitable for lines with two labellers. Both variants can serve between three and nine lanes in the Variopac Pro.
The system is designed for standard container types, including glass and PET bottles and cans, with diameters ranging from 40 to 125 millilitres. It is also intended for irregularly shaped containers, using positive-fit precision grippers to position and orient products, including label alignment within packs.
The system uses delta robot technology with parallel kinematics, allowing all axes to operate simultaneously. Drives are fixed in position rather than moving with the system, and conveyors are powered by permanent-magnet motors which Krones said use up to 50 per cent less energy than conventional asynchronous motors.
The system also includes safety functions that respond to operational disruptions. If containers fall or conditions change, the system detects the issue and triggers an emergency stop. Gripper guide paddles are magnetically attached and detach during collisions to reduce mechanical damage.
Krones said the system can reduce line footprint by up to 10 per cent. The smaller version can adjust container speed to as low as 16 per cent of line speed, reducing the need for additional conveyor systems. The larger version does not include variable speed control but eliminates the need for an inliner, allowing labellers, distribution and packing systems to be directly connected.
