VarioStack
VarioStack is a high-throughput tote destacking solution powered by electronic motors delivering reliable, scalable automation without the complexity of pneumatics.
Autonomous, pneumatic-free tote handling
Benefits
Autonomous flow
Tote destacking operates continuously with limited manual intervention, reducing labor costs and improving productivity.
Predictable throughput
Automated destacking enables consistent throughput rates that match downstream automation demands.
Reduced labor dependency
Manual touchpoints are removed, lowering staffing requirements, training burden, and injury risk.
Reduced pneumatics
VarioStack features a fully electric architecture driven by precision electronic motors, eliminating pneumatic systems and reducing mechanical complexity.
Lower cost of ownership
Costs are kept low due to simpler maintenance, fewer wear components, no compressed air, and reduced energy and service requirements.
Reliable staging
VarioStack provides reliable staging, storage, and retrieval of accumulated empty totes in a single area.
Retrofit ready
Designed for seamless integration into existing brownfield systems or new greenfield installations, requiring only four connections.
Operator focus
Automated unstacking allows operators to shift focus to high-value product and inventory processes rather than manual handling.
Safety compliant
Equipped with safety light curtains and functional safety features, including safety-rated PLC and PROFIsafe motion control.
The Körber advantage
