Basic skeleton of warehousing intelligent equipment
According to the height, the height of 5 meters, 5-15 meters, and 15 meters or more are called low, medium and high-rise shelves. In 1963, the United States invented an automated stereo library; in the mid-1960s, Japan began to build an elevated warehouse; in 1980, China’s first automated stereo library was put into operation. This three-dimensional library developed by Beijing Crane Transportation Machinery Design Research was highly Has reached 15 meters.
In the early days, the three-dimensional shelves were mainly used in manufacturing, port and other scenes. Because the goods were mostly large items, in order to save warehouse space and reduce costs, the shelf design was relatively large and went straight to the top. After the development of e-commerce, the height of the shelves has also changed.
From 2000 to 2009, e-commerce gradually entered a stable period of sustainable development. In 2003, Taobao was founded. Most of the warehouse goods in the e-commerce and retail scenes were small pieces. In the past, the shelves were too high. The speed of such warehouses could not be met, and the height of the shelves dropped to less than 5 meters to meet the surge in orders for e-commerce platforms.
Shelves are one of the basic facilities of the warehouse, and in addition to the shelves, conveyors, high-speed sorting systems also occupy an important position in the warehouse.
The conveyor can be classified according to the presence or absence of gravity. Gravity conveyors can be divided into three types: roller type, drum type and ball type due to different rolling elements. Power conveyors are generally powered by electric motors, depending on the driving medium. It can be divided into a roller conveyor, a belt conveyor, a chain conveyor, and the like.
It should be noted that although the conveyor can transport large items, there are also problems that the transportation route is not easy to change and the floor space is too large.
The high-speed sorting system generally consists of a control device, a sorting device, a conveying device, and a sorting port. The goods on the main conveyor are automatically classified by the control device by identifying, receiving and processing the sorting signals, and then according to the sorting instruction issued by the control device, the sorting device can change the running direction of the goods on the conveying device.
It is worth mentioning that there are many types of sorting devices, such as push-type, floating-out, tilt-type, etc., just open the video about the automatic sorter, and the floating block placed on the conveyor belt is gently tweeted, the main The items on the conveyor quickly slide into the next sorting lane.
It is understood that manual labor can only sort about 150 pieces per hour, while pure manual sorting labor intensity is extremely high, and the automatic sorting system can run continuously for more than 100 hours, sorting 7,000 pieces of packaged goods per hour, and improving efficiency. The reduction in labor costs is self-evident.
