SG Holdings Group’s next-generation large-scale logistics center, ‘X Frontier,’ located on the 3rd floor of the Sagawa Express relay center (hereinafter referred to as ‘X Frontier’), introduced 12 units of ‘Lexx500’ from December 1, 2022, successfully achieving large-scale automation of irregular cargo transportation operations that had previously relied on manual labor.
By addressing the transportation tasks in environments where conventional AGVs were inadequate due to the presence of people and carts intermingling, we succeeded in ensuring stable processing capacity even during the late-night hours when manpower tends to be scarce.
The initiation of the project was triggered by our application to Sagawa Express’s open innovation program, ‘SAGAWA ACCELERATOR PROGRAM.’ After being selected for the program, we conducted demonstration experiments starting from whether automated transportation of irregular cargo by robots was feasible. Recognizing the practicality of our product, we were awarded the Special Jury Prize. This achievement led to the initiation of the current project.
At X Frontier, 90% of the processing is done by automatic sorting machines consisting of belt conveyors. However, irregular items that cannot be transported by the automatic sorting machines were still manually sorted and transported using carts. In the past, we attempted automation through robot introduction but faced challenges due to the constant flow of goods and people in the environment, leading to inflexible transportation processes.
Lexx500 combines AMR technology (Autonomous Mobile Robot) capable of autonomously detecting and bypassing obstacles like automatic driving, and AGV technology (Automated Guided Vehicle) capable of ensuring repetitive accuracy and operational speed. This enabled the automation of cart transportation to truck bays and the return of empty carts.
By continuously operating during the late-night hours when securing manpower is difficult, we increased the processing capacity during the same period and improved stays of cargo.
After the implementation, we received feedback from customers regarding both positive aspects and areas needing improvement. As positive points, they mentioned the ease of operation when starting the robots and task instructions on the tablet, as well as the excellent user interface that makes it easy to see the robots executing tasks and their current positions. Additionally, they appreciated the stable operation in handling transportation regardless of the volume or weight of the cargo.
On the other hand, there are strong demands for continued stable support systems, such as prompt responses and resolution of issues when problems occur. In response to these requests, LexxPluss will continuously improve its support system and response processes to ensure customers can use our services with peace of mind.
LexxPluss will continue to aim for further solving challenges in the logistics and manufacturing industries, which support Japan’s infrastructure
