[0002] With the rapid development of the e-commerce industry, consumers' demands for goods are becoming increasingly diversified, and the categories of goods are becoming more and more abundant; and the mail processing center, as a key link in the logistics chain, is responsible for sorting and delivering various types of mail accurately and efficiently to the destination.

[0003] However, today's sorting methods can no longer meet the needs of sorting all categories of small mail. On the one hand, there are a large number of small special-shaped items that are difficult to detect, transport and accurately sort due to thickness, weight and other reasons. These small special-shaped items cannot be included in the standard sorting process and need to be handled separately, occupying a large amount of work area. At the same time, for these small special-shaped items, most processing centers use manual belt conveyor sorting, sorting shelves and various small special-shaped automated equipment to handle them. This not only takes up a large amount of site area, but also has high labor costs, making it difficult to cope with the growing sorting needs. Utility Model Content

However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0022] Example:

[0023] Please refer to Figure 1 As shown, the utility model provides a small mail sorting system for all specifications, including a feeding system and a sorting system;

[0024] Among them, the feeding system adopts an integrated feeding form of disassembly and supply, which reduces the occupation of the working area; specifically, the feeding system includes two groups of first unpacking stations 11 for disassembling the general package into small pieces. One side of these two groups of first unpacking stations 11 is respectively connected to two groups of manual diversion and sorting feeding lines 12 to divert and disassemble some small general packages and loose parts to the lower-level small and special-shaped parts sorting machine, supplement the flow of the lower-level sorting machine, and reduce the pressure of the upper-level sorting machine; and sort out the loose and special-shaped parts to the lower-level small and special-shaped parts sorting machine.

[0025] The sorting system includes an upper-level sorting mechanism and a lower-level sorting mechanism. The upper-level sorting mechanism is responsible for quickly sorting standard small parcels, while the special-shaped small parcel sorting machine of the lower-level sorting mechanism specializes in handling special-shaped small parcels, thereby realizing efficient sorting of different types of small parcels. Specifically, the upper-level sorting mechanism includes a small parcel general package circulation line 21 and an upper-level standard small parcel sorting machine 23. The two groups of first unpacking stations 11 are respectively connected to the small parcel general package circulation line 21 through two groups of general package main lines; the lower-level sorting mechanism includes a special-shaped small parcel sorting machine 33. One side of the small parcel general package circulation line 21 is connected to the special-shaped small parcel sorting machine 33 and the upper-level standard small parcel sorting machine 23 through the feeding system.

[0026] One side of the two groups of manual diversion and sorting feeding lines 12 is connected to the lower-level special-shaped small-piece feeding line 13. Specifically, the two groups of first unpacking stations 11 dynamically divert and unpack the bulk packages to the manual diversion and sorting feeding line 12 and the small-piece bulk package circulation line 21 according to the total amount of mail of the rear-end special-shaped small-piece sorting machine; this dynamic diversion setting can divert standard small-piece bulk packages and a small number of special-shaped small pieces for external use, avoiding occupying the resources of the upper-level sorting machine and further improving the overall sorting efficiency; at the same time, the participation of manual diversion and sorting processes also ensures the identification and classification of special-shaped small pieces.

[0027] The lower-level sorting mechanism also includes two groups of large chutes 14 for feeding special-shaped small parts. The other ends of the two groups of lower-level special-shaped small part feeding lines 13 are respectively connected to two groups of large chutes 14 for feeding special-shaped small parts, and these two groups of large chutes 14 for feeding special-shaped small parts are connected to the special-shaped small part sorting machine 33 through the lower-level manual packaging station; ensuring that special-shaped small parts can be transported to the lower-level manual packaging station through the two groups of large chutes 14 for feeding special-shaped small parts, and then sorted and processed by the special-shaped small part sorting machine 33, avoiding occupying the resources of the upper-level standard small part sorting machine 23; the setting of the special-shaped small part sorting machine 33 further improves the sorting efficiency of special-shaped small parts.

[0028] The feeding system also includes two groups of semi-automatic feeding lines 15 and four groups of fully automatic feeding lines 16, which further enrich the feeding capacity of the system. Specifically, two groups of second unpacking stations 17 are provided on the small-part general contracting circulation line 21, and the two groups of second unpacking stations 17 are respectively connected to one end of the two groups of semi-automatic feeding lines 15; at the same time, four groups of third unpacking stations 18 are also provided on the small-part general contracting circulation line 21, and the four groups of third unpacking stations 18 are respectively connected to one end of the four groups of fully automatic feeding lines 16; the coexistence of such semi-automatic feeding lines 15 and fully automatic feeding lines 16 ensures that the system can adopt flexible feeding methods according to the characteristics of different types of small parts, thereby improving the overall feeding efficiency; the other ends of the two groups of semi-automatic feeding lines 15 are respectively connected to the four groups of semi-automatic feeding tables 32, while the other ends of the four groups of fully automatic feeding lines 16 are respectively connected to the eight groups of fully automatic feeding tables 31.

[0029] By directly connecting each unpacking station to the corresponding infeed table or infeed chute, the system effectively reduces the diversion process of small and bulk pieces, the conveying distance and the single-line conveying volume, thereby reducing the probability of mail damage and jams; at the same time, the two groups of manual diversion and sorting infeed lines 12 are connected to the small-piece general packaging circulation line 21, and the reasonable layout of different unpacking stations and infeed tables and infeed lines makes the entire sorting process more compact and efficient; in addition, the system is also equipped with a fully automatic infeed table 31 and a semi-automatic infeed table 32, combining the advantages of automation and manual assistance; this not only improves The feeding efficiency and accuracy are improved, and manual intervention can be carried out under specific circumstances to ensure the stable operation of the system. This solves the problem that the traditional sorting method occupies a lot of space and has high labor costs, making it difficult to meet the growing sorting needs. It not only improves space utilization, but also reduces operating costs, providing logistics centers and express sorting centers with more efficient and reliable solutions. It is an important technological breakthrough in the field of modern logistics automation; four groups of semi-automatic feeding tables 32 and eight groups of fully automatic feeding tables 31 are all connected to the upper standard small piece sorting machine 23 through the upper sorting loop to process standard small pieces.

[0030] After individual separation and visual identification, the small parts on the fully automatic feeding line 16 can be diverted according to their characteristics. Specifically, standard small parts will be diverted to the fully automatic feeding table 31 for subsequent automatic sorting processing; while special-shaped small parts will be diverted to the lower-level special-shaped small parts feeding line 13 for subsequent processing by a special special-shaped small parts sorting machine 33; this dynamic diversion mechanism based on automatic identification ensures that standard small parts and special-shaped small parts can be sorted and processed in a targeted manner, avoiding occupying each other's resources and further improving the processing efficiency of the sorting system.

[0031] On one side of the small parts general package circulation line 21, there is also a receiving and special-shaped parts rejection line 22. Through the combination of visual recognition and sorting of the front-end feeding line and manual rejection, special-shaped small parts can be accurately rejected, ensuring that standard small parts are fed to the upper standard small parts sorting machine 23 in an orderly manner, realizing accurate sorting; this rejection mechanism combining automation and manual collaboration ensures the efficient supply of standard small parts, laying the foundation for the stable operation of the upper sorting mechanism; in addition, small parts that fail to be fed by the fully automatic feeding table 31 are automatically returned to the receiving and special-shaped parts rejection line 22 for processing through the chute at the end of the feeding table, avoiding error accumulation and further improving the stability of the system; while the semi-automatic feeding table 32 cannot The upper parts are manually diverted to the receiving parts and special-shaped parts rejection line 22 through the chute; the received mails of the upper standard small parts sorting machine 23 are diverted to the receiving parts and special-shaped parts rejection line 22 through the chute. One end of the receiving parts and special-shaped parts rejection line 22 is connected to the lower special-shaped small parts feeding line 13 to transport the receiving parts and special-shaped small parts to the special-shaped small parts sorting machine 33 for processing. The special-shaped small parts sorting machine 33 adopts non-contact scanning and recognition technology, which can quickly and accurately sort special-shaped small items, reduce dependence on manual labor, and further reduce labor investment costs, so that the sorting system can comprehensively and efficiently handle various types of small parts, providing a more intelligent solution for logistics centers and express sorting centers.

[0032] The specific usage and function of this embodiment are as follows:

[0033] First, the specific feeding process of the feeding system. Before the mail enters the small-piece package circulation line 21, the total package is manually diverted to the manual diversion and sorting feeding line 12 based on the total amount of mail in the back-end sorting machine. At the same time, some special-shaped pieces that have escaped will be removed. After that, the mail enters the small-piece package circulation line 21, and after manual unpacking at the second unpacking station 17 and the third unpacking station 18, the small pieces are fed to the semi-automatic feeding line 15 and the fully automatic feeding line 16. After single-piece separation and visual identification, these small pieces will be intelligently diverted to the fully automatic feeding table 31 or the lower-level special-shaped small piece feeding line 13 at the back end. If the fully automatic feeding table 31 fails to feed, these small pieces will automatically return through the chute at the end of the feeding table. The small pieces are sent to the receiving and special-shaped piece rejection line 22 for processing; the semi-automatic feeding line 15 directly transfers the small pieces to the two-in-one manual semi-automatic feeding table 32 at the rear end. While feeding, some special-shaped small pieces are rejected by the manual feeding and sent to the receiving and special-shaped piece rejection line 22; the upper standard small piece sorting machine 23 will converge the rejected special-shaped small pieces and transport them to the receiving and special-shaped piece rejection line 22; the receiving and special-shaped piece rejection line 22 will converge the receiving pieces and special-shaped small pieces and transport them to the lower special-shaped small piece feeding line 13, and supply them to the special-shaped small piece sorting machine 33 for processing through the large special-shaped small piece feeding chute 14; and the standard parts successfully fed by the fully automatic feeding table 31 and the semi-automatic feeding table 32 will be processed by the upper standard small piece sorting machine 23.
