1. Expansion of Large-scale E-commerce Distribution Warehouse that Takes Advantage of Extensibility of AGVs
In March 2017, Hitachi received an order for the system expansion of an e-commerce distribution warehouse to which it had previously delivered 154 automatic guided vehicles (AGVs) due to an increase in warehouse scale. Starting in April 2019, the warehouse began operations as a distribution base that can handle an inventory of 350,000 items while making up to 40,000 deliveries (orders) per day.
This system expansion work took advantage of the “phased equipment capability improvement” feature of AGVs, leading to improved distribution capabilities through the implementation of the following three items:
- Increased number of AGVs
- Expansion of storage area for AGVs and storage racks
- Expanded picking stations*
In addition, Hitachi adopted a picking method utilizing projection mapping technology that can visualize the positions and quantities of items to pick, to improve work productivity.
Although it is generally necessary to halt the use of previously installed equipment during on-site construction work, this expansion project was completed without interfering with operations due to the flexible extensibility of AGVs.
