At CE China, which opened on May 3, 2018 in Shenzhen, Suning Tesco demonstrated their logistics AGV robot work scene. This kind of logistics AGV robot can greatly reduce the manpower in the logistics warehouse.
According to the reporter's understanding, the size of the AGV robot is 1020X950X500mm, its own weight is 160KG, and it can walk freely on the shelf of 800Kg. When there is no power, the AGV robot can automatically return to the charging pile to charge itself. This function is very worry-free.
This robot has been officially launched at Shanghai Fengxian Logistics Base. The application of this robot makes the selection of goods no longer chasing the shelves, but waiting for the robots to hang up on the shelves, and to realize the "goods to people" selection by moving the robots to move the shelves, breaking the traditional "people" Arrival picking mode.
At present, there are a total of 270 robots in the Shanghai AGV robot warehouse. There are two combinations of the same robot, and the 200 sets are a combination of robot and shelf, mainly carrying 3C small pieces and disassembled parts. The average picking time of a single item is 10 seconds, the efficiency of picking small items is more than 5 times, and the picking accuracy is over 99.99%.
The 70 groups are robots and pallets, which are used for 3C merchandise and bulk handling. The AGV pallet robot has an overall product picking efficiency of more than 10 times. The average picking time of a single item is 10 seconds, and the picking accuracy is over 99.99%. Compared to the AGV robot that hauls the small commodity shelves, the pallet robot can carry up to 800 kilograms, which is equivalent to a performance of 200 computer monitors.
Therefore, to calculate the manpower of this kind of usage, an AGV robot can replace 10 workers, reducing the number of laborers in a warehouse from 50-70 people to only about 5 people to be responsible for the operation of the robot.
The use of a large number of AGV robots improves the efficiency of intelligent warehousing, speeds up logistics, and saves labor costs. At present, Jingdong, rookie, Suning and other warehouses are increasingly using such robots.
AGV: Automated Guided Vehicle (AGV), the most common applications such as: AGV handling robot or AGV car, the main function is concentrated in automatic logistics transfer, which is the application of warehousing logistics such as Suning and Jingdong mentioned above. The AGV handling robot automatically transports items to designated locations via special landmark navigation.
The three most common ways to boot are:Electromagnetic induction type: that is, our most common magnetic strip navigation. By attaching magnetic tape to the ground, the AGV automatic truck will be equipped with an electromagnetic sensor at the bottom of the vehicle to sense the ground magnetic stripe landmark to realize automatic driving and transporting goods. It depends on the different arrangement of the magnetic stripe polarity.
Laser-sensing: The laser scanner recognizes a number of fixed markers set within its range of motion to determine its coordinate position, thereby guiding the AGV operation.
RFID Inductive: Automatically detects coordinate positions through RFID tags and reading equipment, enabling automatic operation of AGV cars. Site definitions can be arbitrarily defined by chip tags, even the most complex site settings can be easily completed.
At present, the most advanced and most scalable is guided by UHF RFID developed by Microcree Technology.
With the development of industrial automation, computer integrated manufacturing system technology, and the wide application of flexible manufacturing systems and automated warehouses, AGV is the necessary automatic handling and handling method for contacting and regulating discrete logistics management systems to make their operations continuous. And the level of technology has developed rapidly.
However, the domestic AGV robot industry still faces some problems.
The core components mainly depend on foreign products: AGV robots are mainly composed of three parts, drive, system and guidance. Core components such as drive controllers, systems, and exciting navigation sensors are still the world of foreign brands. There are very few companies in China that can increase R&D investment, and high-end talents are hard to find. Compared with foreign giants, there is still a big gap in technology, and the localized supply chain is very weak.
The phenomenon of homogenization is serious: logistics storage machine technology, whether hardware or software, needs constant innovation and launches a trustworthy product. However, at present, domestic AGV enterprises basically have you and I have to develop a new product. Once it is introduced to the market, the second and third companies will change their appearances. They will be launched one after another. The patent is basically a waste paper. .
Industry standards are difficult to unify the industrial development: domestic AGV is still a relatively subdivided field, related industry standards and product standards are very scarce, product quality is uneven, and market applications are also difficult to achieve standard unification and price warfare.
