After a buyer purchases an article on the internet, a seller feeds back information of the article to a large warehouse for storing the article according to the information of the article, and a warehouseman (or the seller) feeds back the information of the article to an express service station again; the express service station encodes information such as names and mobile phone numbers of the article addressees, the edited article bar codes have single and unique information, and express service station personnel store and input the information of the article bar codes into a computer; thus, a huge customer data database is built. The express delivery service station personnel can package the express delivery pieces with large batch of recorded information on the same day and convey the express delivery pieces to a sorting center of an express company in specified time. The full-automatic express item sorting system can be suitable for large, medium and small sorting stations of a logistics center of an express company; the utility model can also be used for sorting articles in a laboratory or a production workshop.
When the full-automatic express item sorting system is used, firstly, large and disorderly express items are poured into the slipping dispersion device 1 at the input end of the sorting system, and the express items are primarily dispersed by the slipping inclined plates 21 of the slipping dispersion device 1 according to different gravity borne by the express items; then, the preliminarily dispersed express items enter the vibration dispersing device 2, and the vibration of the inclined vibration table 25 of the vibration dispersing device 2 is utilized to efficiently disperse the express items and avoid the stacking and blocking of the express items. Then, the high-efficiency dispersed express delivery pieces sequentially pass through a low-speed roller group 33, a medium-speed roller group 34 and an oblique high-speed roller group 35 of the gradient separation device 3; and the speed difference (the speed is gradually increased) existing between the three sections of roller shaft groups of the gradient speed separation device 3 is utilized to realize the dispersion of the express items. When the express delivery passes through the inclined high-speed roller shaft group 35 at the tail end of the gradient separation device 3, the disorderly express delivery is aligned and aligned one by one due to the combined action of the rollers with certain arrangement angles and the side baffles 37 arranged at two sides of the inclined high-speed roller shaft group 35; in addition, after passing through the gradient speed separation device 3, each express delivery piece is separated by a certain distance, so that the subsequent scanning operation is facilitated.
The express delivery piece which is separated and straightened at the speed of gradient is photographed on five faces (front, upper, rear, left and right) of the express delivery piece through a first scanning door 4, and then detailed information (such as bar codes, two-dimensional codes, mobile phone numbers, mailing addresses, senders, receivers and the like) on the express delivery piece is read; and then, transmitting the photo information to a control system host, and performing data analysis and division of the affiliated area by the control system host. After the express item passes through the first scanning gate 4, the following two situations occur: 1. the first scanning door 4 scans the information of the express items normally; 2. the first scanning gate 4 fails to scan out the information of the courier (courier including information missing).
When the express delivery belongs to the first condition, namely the first scanning door 4 scans the information of the express delivery; the scanned information can be transmitted to a control system host, after the host comprehensively analyzes the express delivery data, a shunting mechanism I5 on the turnover conveying roller way 6 can be started, a shunting push plate 41 is driven to rapidly separate the express delivery scanned with the information from the turnover conveying roller way 6, and the express delivery enters an upper-layer sorting roller way 16 of a double-layer sorting device 12 through an upper-layer conveying roller way 8 which is arranged in a downward inclination manner and is conveyed; and then the corresponding distribution mechanism II 11 on the upper-layer sorting roller way 16 pushes the express delivery to the corresponding express receiving device 15, so that the zone-based and position-based sorting of the express delivery is realized.
When the express delivery belongs to the second condition, namely the first scanning door 4 does not scan the information of the express delivery; at this moment, the shunting mechanism I5 on the overturning conveying roller way 6 cannot be started, and the express delivery piece continues to move forwards on the overturning conveying roller way 6. The express delivery piece enters an accommodating cavity between two adjacent flat plates of the cross turnover plate 47 of the turnover device 7, and touches the infrared sensor, so that the turnover driving device is driven to drive the cross turnover plate 47 to rotate; the rotation of the cross-shaped turnover plate 47 causes the express delivery piece to turn over, the bottom surface (the surface which cannot be scanned by the first scanning door 4) which is originally positioned at the lower part of the express delivery piece is turned over to be positioned at the top surface of the upper part, and the express delivery piece slides to the lower-layer conveying roller way 10 by the gravity of the express delivery piece to be conveyed; and the express delivery piece on the lower layer conveying roller way 10 passes through the second scanning door 9 to carry out secondary scanning. The second scanning door 9 can also realize the scanning of the front, upper, rear, left and right surfaces of the express delivery piece and finish the uploading of information; the second scanning door 9 is matched with the first scanning door 4 for use, so that the omnibearing dead-angle-free and omission-free scanning of the express delivery piece is realized.
The express delivery piece passing through the second scanning door 9 continues to move forward on the lower layer conveying roller way 10, and finally enters the lower layer sorting roller way 14 of the double-layer sorting device 12 to be conveyed; the host computer of the control system comprehensively analyzes the data of the scanned express items again, and pushes the scanned information express items to the corresponding express receiving device 15 through the sorting outlet 13 through the corresponding flow distribution mechanism III 18 on the lower-layer sorting roller way 14, so that the regional and position sorting of the express items is realized. However, some defective express delivery items whose information cannot be scanned through the second scanning door 9 are conveyed along the lower sorting roller way 14 to the damaged express delivery recycling device 17 at the end, and then enter the manual processing area to be manually scanned and distributed.
