With the aim of increasing sorting capacity, we have introduced a shuttle rack as a packing system that can handle approximately 3,000 incoming and outgoing cases per hour. We have strengthened the shipping function for the last mile such as e-commerce. In the past, cargo that had been picked and packed and was waiting for shipment remained in the cargo handling area, hindering the effective use of the space in the logistics facility, but after the introduction of the Shuttle Rack, the shipping buffer function and transport control function have been improved, and the work has been streamlined.
