Tote-to-Person Automation

Tote-to-Person Automation

Taking vertical space utilization up a notch

So many SKUs to store, so little space. It’s a problem getting more difficult – and more expensive – by the day. 

That’s why many retailers and 3PLs are maximizing per-square-foot utilization by leveraging vertical storage space and increasing throughput from the forward-picking zone. 

GreyOrange Tote-to-Person (TTP) solutions provide the flexibility and vendor-agnostic foundation necessary to create truly omnichannel, agile fulfillment centers. Through the combination of tote/carton handling applications with real-time adaptability to dynamic channel and SKU popularity, warehouses and distribution centers (DCs) are able to:

  • Maximize vertical space utilization and storage density
  • Easily scale up or down for changes in throughput or footprint
  • Simultaneously use vertical tote mover (VTM) and horizontal tote mover (HTM) robots for increased performance and speed
  • Accommodate oversized inventory in a hybrid storage system

Ranger™ TTP: Reach new heights

Uniting vertical access and Autonomous Mobile Robot (AMR) flexibility, Ranger TTP optimizes high-density storage up to 33 feet, transforming your space and productivity.

  • Space utility: Vertical buffer and lifts for height utilization
  • High throughput: Up to 35 totes in and 35 totes out per hour, per bot
  • Flexible infrastructure: Fast setup and go live with minimal fixed infrastructure
  • Storage efficiency: Multilayer tote and carton picking of different sizes
  • World class safety: UL and CE Certified, obstacle detection, safety contact edges, sound alarm, emergency stop button, anti-collision lifting, and fall protection

Relay Pick: Dynamic duo for next-level vertical automation

Relay Pick harnesses the power of two agents to boost warehouse speed, density and scalability. VTMs and HTMs work in tandem for high-speed tote delivery to stations for fulfillment.

VTMs 

  • Transfer totes within aisles from storage to cantilevers
  • Rearrange totes within a storage bay based on popularity & available order

HTMs 

  • Transfer totes from cantilevers to stations and vice versa at a speed of 13 ft/s 
  • Auto-lift totes for improved operator ergonomics and experience

 

Relay Pick offers industry-aligned storage units and versatile station designs tailored to meet specific operational needs, reducing operator effort and maximizing efficiency at every step.

Relay Pick Benefits

Accelerate Fulfillment. Maximize Space.

  • High density, high performance: Relay Pick supports up to 5 deep storage while delivering 400 tote presentations and 650 lines per station per hour, maximizing throughput and space efficiency.
  • Cost-effective and scalable: Designed with a lower bill of materials, Relay Pick is a cost-efficient solution that easily expands to accommodate increased throughput and storage needs.
  • Fast deployment: With simpler infrastructure and faster solutioning, Relay Pick can go live in less than 9 months.
  • Reliable stability: Reduced complexity and streamlined design result in fewer faults, ensuring consistent performance and operational stability over the long term.
