AGV creates flexible logistics solutions for Yizheng Factory, a wholly-owned subsidiary of Sinopec, one of the world's top 500 companies. Through on-site inspections, AGV learned that the company's logistics links involve a number of factories, and the handling process includes finished product warehouse loading and unloading/outdoor transshipment - automatic loading and unloading of three-dimensional warehouses/warehousing palletizing/buffer delivery, etc., AGV provides services from all aspects such as program planning, system integration, equipment selection, installation and commissioning, technical training, after-sales service, etc., and a complete set of unmanned and flexible turnkey projects to help enterprises promote system optimization, reduce costs and increase efficiency, and accelerate intelligent upgrading.
Solution
The core products provided by AGV include a number of outdoor unmanned tractor AGVs, stacking unmanned forklift AGVs, and smart logistics solutions composed of AGVS (dispatching system), WMS (warehouse management system) and WCS (warehouse control system) for smart logistics, helping the company build a benchmark for intelligence in the petrochemical industry.
1. Cross-plant outdoor transfer
The traction AGV adopts laser SLAM navigation technology to support the operation of open and dynamic scenes, and the vehicle body is equipped with an automatic decoupling function, which can efficiently complete the handling needs without manual intervention.
2. Unloading and warehousing in the unmanned forklift room
Under the task of the production system, the AGVS dispatching system communicates with WCS and WMS in real time, and intelligently schedules the interaction between different models in complex scenarios. After the outdoor traction AGV completes the front-end logistics distribution, the unmanned forklift linkage forklifts the goods on the outdoor traction AGV material rack, and docks with the roller line system in the three-dimensional warehouse to complete the stacking action of the goods on the roller line, and then the stacker receives the system instructions to complete the warehousing data chain of the one-trailer material.
3. Outbound delivery
The unmanned forklift completes the last mile handling task, transports the materials from the conveyor line to the shipping buffer area, and feeds back the working status to the system for storage and analysis in real time, that is, the "unmanned" logistics closed-loop mode is formed.
Benefits
The smart logistics solutions provided by AGV for the subsidiary optimize the actual logistics and information flow of the factory by 95%, reduce the comprehensive energy consumption by 5%, increase the logistics turnover efficiency by 13%-25%, and save the labor cost by 30%.
The project is innovative
1. Outdoor long-distance application, from indoor to outdoor
Outdoor scenarios mean that robots face more complex environments and need to have stronger communication capabilities, environmental adaptability, and perception capabilities. Based on mastering the core navigation and positioning technologies of mobile handling robots, AGV has continuously optimized the top-level technology, so that AGVs can complete scene recognition and mapping, pose positioning, and intelligent planning learning in an outdoor open environment, breaking through the technical difficulties of unmanned mobile robots in the outdoors.
2. The automatic loading and unloading accuracy of unmanned forklifts ±5mm
There can be no error in the parking accuracy of outdoor traction AGV and the forklift accuracy of unmanned forklifts, which requires the positioning accuracy of the model to be very accurate, and the positioning accuracy of AGV laser SLAM navigation technology can reach ±5mm. The unmanned forklift adopts image recognition and tracking technology, which can automatically correct the pallet; Traction AGV adopts repositioning technology to improve local positioning accuracy.
Industry influence
1. Expansion of handling robot scenarios
In the AGV industry, AGV took the lead in landing two types of application scenarios with greater technical difficulties, namely outdoor traction AGV and unmanned forklift automatic loading and unloading, and under the deployment of AGVS system, different AGV models completed high-efficiency operations across the plant. AGV's breakthroughs in key technologies and application scenarios expand the application of AGV in more complex and dynamic scenarios.
2. Model project in petrochemical industry
For the petrochemical industry, after achieving phased results in automation and digital construction, the company has gradually deepened the application of cost-reduction, quality and efficiency improvement measures such as production operation optimization, production operation optimization, energy management optimization and equipment asset optimization, so as to further enhance the comprehensive competitiveness of the enterprise.
