Application
  • Motorola Microcontroller Technologies Group (MCTG) Distribution Center -- Austin, TX.
  • Tote buffer storing microprocessors, microcontrollers, and memory chips for distribution to customers worldwide.
Key Customer Benefits
  • Frees up 30% of available floor space.
  • Increases storage capacity to accommodate increasing shipping volumes.
  • Improves order-picking efficiency by 20%.
  • Supports initiative to eliminate corrugated packaging in manufacturing and test areas.
Material Flow Requirements
  • Increase storage capacity using less floor space.
  • Streamline the order-picking process.
  • Integrate material flow hardware and software with existing host computer.
Material Flow Hardware
  • Two-aisle mini load automated buffer with 2,244 storage locations.
  • Three Sorting Transfer Vehicles (STV) on a loop system.
  • Eight carousel storage buffers.
  • Eight ergonomic order-picking workstations.
Computer Control System
  • Real-time inventory control system with a real-time connection to Motorola's host computer.
Material Flow Process

Input
  • Totes are received at an input conveyor and picked up by an STV.
  • Host computer determines whether a tote's contents are to be shipped immediately or stored in the mini load.
  • STVs deliver totes to the mini load for storage or to a workstation for order picking.
  • Mini load receives up to 22 totes per hour.
Output
  • Host computer sends orders to inventory control software, which directs the mini load to pull the ordered totes.
  • Once retrieved from the mini load, totes are transferred to an STV, which delivers them to the assigned pick workstation.
  • Terminals at each workstation provide pick instructions and allow workers to update the host when the pick is completed.
  • If parts remain in the tote, it is returned to the mini load via STV.
  • Orders for parts stored in the carousels are processed at adjacent pick workstations.
  • When an order is complete, the order is returned to an STV, which delivers it to an output conveyor for consolidation and shipping.
