When a buyer purchases an item online, the seller will feed back the information of the item to the large warehouse where the item is stored, and the warehouseman (or seller) will feed back the information of the item to the courier service station; the courier service station will send the item The information such as the name and mobile phone number of the recipient is encoded, and the edited item barcode has a single and unique information. The express service station personnel will store and input the information of the item barcode into the computer; thus, a huge Customer profile database. The courier service station personnel will pack a large number of courier items with recorded information on the day, and deliver them to the sorting center of the courier company within the specified time. The fully automatic express sorting system can be applied to large, medium and small sorting stations in the logistics center of express companies; it can also be expanded to sort items in laboratories or production workshops.

When the automatic express delivery sorting system is in use, firstly, a large number of disorderly express deliveries are dumped into the downhill dispersing device 1 at the input end of the sorting system, and the express items rely on the different gravitational forces they receive to pass through the downhill dispersing device 1. The toboggan ramp 21 performs preliminary dispersion; then, the initially dispersed express items enter the vibration dispersion device 2, and use the vibration of the vibration dispersion device 2 inclined vibrating table 25 to efficiently disperse the express items and avoid stacking and blocking of the express items. Then, through the efficiently dispersed courier, successively pass through the low-speed roller group 33, the medium-speed roller group 34 and the oblique high-speed roller group 35 of the ladder-speed separation device 3; The speed difference between them (the speed increases step by step) realizes the discreteness of express delivery. When the express delivery passes through the oblique high-speed roller group 35 at the end of the ladder-speed separation device 3, due to the joint action of the rollers with a certain arrangement angle in the oblique high-speed roller group 35 and the side baffles 37 on both sides, the The messy express items are straightened one by one; in addition, after passing through the ladder speed separation device 3, there is a certain distance between each express item, so it is convenient for subsequent scanning operations.

The courier that has been separated and straightened at the ladder speed takes photos of the five sides of the courier (front, top, back, left, right) through the first scanning gate 4, and then reads the detailed information on the courier (for example: barcode) , two-dimensional code, mobile phone number, mailing address, sender and recipient, etc.); after that, the photo information is transmitted to the control system host, and then the control system host performs data analysis and divides the area. After the express delivery passes through the first scanning gate 4, the following two situations will occur: 1. The first scanning gate 4 normally scans out the information of the express delivery; 2. The first scanning gate 4 fails to scan out the information of the express delivery (including information Incomplete courier).

When the courier belongs to the first situation, that is, the information of the courier is scanned by the first scanning door 4; the scanned information will be transmitted to the host of the control system, and the host will start to turn over the conveying roller after comprehensively analyzing the data of the courier The diversion mechanism I5 on 6 drives the diversion push plate 41 to quickly separate the express items whose information has been scanned out of the inverted conveying roller table 6, so that the express items enter the double-layer sorting through the upper conveying roller table 8 arranged in a downward slope. The upper layer sorting roller table 16 of the device 12 is transported; and then the corresponding distribution mechanism II11 on the upper layer sorting roller table 16 pushes the express delivery to the corresponding express delivery receiving device 15, so that the express delivery can be sorted by area and by area. bit sorting.

When the courier belongs to the second situation, that is, the first scanning gate 4 does not scan out the information of the courier; at this time, the diverting mechanism I5 on the turning conveyor roller 6 will not start, and the courier will be on the turning conveyor 6. move on. The courier item enters into the accommodating cavity between two adjacent flat plates of the cross turning plate 47 of the turning device 7, and touches the infrared sensor, and then drives the turning drive device to drive the cross turning plate 47 to rotate; the rotation of the cross turning plate 47 causes The courier is turned over, and the bottom surface (the side that cannot be scanned by the first scanning door 4) originally located in the lower part of the courier is turned over to be located on the top surface of the upper part, and the courier is allowed to slide down to the lower conveying roller table 10 by its own gravity. Conveying: the courier on the lower conveying roller table 10 passes through the second scanning gate 9 for secondary scanning. The second scanning door 9 can also realize the scanning of the front, upper, rear, left and right sides of the express delivery, and complete the uploading of information; Azimuth without dead angle, scan without omission.

The express items passing through the second scanning gate 9 continue to move forward on the lower conveying roller table 10, and finally enter the lower layer sorting roller table 14 of the double-layer sorting device 12 for conveyance; Through the comprehensive analysis of the data of the parcels, through the corresponding distribution mechanism III 18 on the lower sorting roller table 14, the express parcels whose information is scanned are pushed to the corresponding express receiving device 15 through the sorting outlet 13, so as to realize the sorting of express parcels by area, Sort by bit. However, some incomplete express items whose information cannot be scanned through the second scanning gate 9 are transported to the damaged express recovery device 17 at the end along the lower sorting roller table 14, and then enter the manual processing area. Implement manual scanning and distribution.
