The Middlesex Dynamic Tool Buffer is the natural evolution of material transport systems in production environments built on OHT (Overhead Hoist Transport) technology.
Its global mission in this industry is to correct the defects of existing AMHS (the discrete vehicle based material handling systems). These existing systems require the excessive accumulations of work in process, thus degrading factory cycle time efficiency.
The excessive work flow storage of the discrete vehicle based systems (central stockers and storage shelves in production bays) is reduced with Dynamic Equipment Buffers (DEB) based on our super conveyors.
The primary benefit in using DEBs is the increased utilization efficiency of the existing vehicle transport lines (defined as the number of transport moves with payload vs. the total number of vehicle moves)
This intelligent module, installed near the processing tools, replaces traditional high-cost stockers and dramatically improves FOUP (Front-Opening Unified Pod) flow management.
The Dynamic Tool Buffer’s primary function is to receive FOUPs from OHTs, dynamically store and prioritize them in a circular conveyor buffer, and then make them instantly available for OHT pickup and tool loading.
Unlike static systems, the Dynamic Tool Buffer introduces automated sorting and priority logic, ensuring FOUPs are always available where and when needed. The result is greater efficiency, lower costs, and improved FAB stability.
Once a FOUP is delivered by an OHT into the Dynamic Tool Buffer, the system automatically manages the following steps:
This enables:
The Dynamic Tool Buffer was developed as a core component of the Middlesex-patented Hybrid- AMHS system and is fully compatible with both existing and future OHT infrastructures
Optimized design for intelligent flow management, with savings on installation and maintenance.
Each FOUP is ordered and handled dynamically, improving time-to-process.
No reconfiguration required, works within existing infrastructure.
FOUPs are continuously managed in the circular conveyor buffer, ensuring they are always available for OHT pickup without congestion at the tool port.
Expand capacity by simply adding more buffers. This design eliminates the need for oversized, static stockers by creating a compact, tool-side buffer directly integrated with the OHT line.
Only Middlesex is legally authorized to design and install Dynamic Tool Buffers integrated with OHT systems.
