     Specifically, as shown in  FIGS. 1 and 2 , a sorting device provided in an embodiment of the present disclosure comprises a sorting apparatus  10  movable along a predetermined path and a container delivering apparatus  11  located beneath the sorting apparatus  10 . The sorting apparatus  10  is used to classify and sort out the received goods in accordance with a preset classification rule, wherein the predetermined path is a path determined by the structure and profile of the sorting apparatus  10 , for example, a straight line, a curve, or even a closed ring. The container delivering apparatus  11  is located beneath the sorting apparatus  10 , and can collect and store goods belonging to various lists or categories, through the containers on the container delivering apparatus  11 . 
     The sorting apparatus  10  sorts goods belonging to the same list (e.g. order) into one or more containers, has a high sorting efficiency, and can solve the demand of sorting massive goods according to the list. The sorting apparatus  10  may be in an open linear structure with a linear shape or a curved shape, which is provided with a starting point and an end point, such as an L-shaped, U-shaped, or linear structure. Of course, the sorting apparatus  10  can also be a closed rotary cycle structure, that is, the beginning point and end point of the rotary cycle structure are connected together, making the sorting apparatus  10  be in a closed loop, for example, a circular rotary cycle structure, a rectangular rotary cycle structure or a rotary cycle structure in an irregular shape designed according to a device installation site. Compared with the open linear structure, the closed rotary cycle structure can sort goods continuously and cyclically, and maintain continuous movement to avoid parking of goods, thus improving sorting efficiency and saving device installation space. 
     Taking the rotary cycle structure as an example, a plurality of sorting stations  101  are distributed along a rotary cycle path of the sorting apparatus  10 . Each sorting station  101  is provided with a first discharge port  1011  and a second discharge port  1012  on two sides along the rotary cycle path respectively, and a plurality of containers are placed on the container delivering apparatus  11 , and arranged in a linear array whose direction is a direction of connecting line of the first discharge port  1011  and the second discharge port  1012 , and can reciprocate in the direction of the connecting line of the first discharge port  1011  and the second discharge port  1012 , so that two containers of the plurality of containers are aligned with the first discharge port  1011  and the second discharge port  1012 .

It is understood that the structure of the sorting apparatus  16  may also be a rotary structure of other shapes such as a rectangular shape, and then the sorting apparatus  16  may be in slidable or rolling connection with the bearing bracket  17 , and accordingly, the container delivering apparatus  11  may also be in slidable or rolling connection with the bearing bracket  17 . 
     Optionally, referring to  FIG. 9 , said bearing bracket  17  comprises support brackets  171 , a first rotary bearing  172 , and a second rotary bearing  173 ; 
     the sorting apparatus  10  is articulated with the support brackets  171  through the first rotary bearing  171 , and the container delivering apparatus  11  is articulated with the support brackets  171  through the second rotary bearing  172 . 
     Specifically, as shown in  FIG. 9 , in order to reduce the rotary resistance and improve rotational smoothness, the bearing bracket  17  may comprise support brackets  171 , a first rotary bearing  172 , and a second rotary bearing  173 . 
     The sorting apparatus  10  is articulated with the support brackets  171  through the first rotary bearing  171 , and the container delivering apparatus  11  is articulated with the support brackets  171  through the second rotary bearing  172 , which is thus helpful to improve the rotary efficiency of the sorting apparatus  10  and the container delivering apparatus  11  and facilitating the sorting efficiency. 
     In order to improve the safety of the above device and avoid contaminants from entering into the exposed parts, a main cover plate can be used to block a local area defined by the individual sorting stations along the rotary path. It is understood that in order to avoid interference, there is no need for the maximum size of the main cover plate to reach the discharge port near the rotary center. Similarly, a sorting cover plate can also be used to block a hollow area between each two adjacent sorting stations. 
     It is understood that in the description of the above embodiment, in order to realize the movement of each assembly or mechanism, the power source can be selected as an AC motor or a stepping motor according to actual needs. Of course, the power source of the linear reciprocating motion assembly may also be a telescopic cylinder, etc., which is not described repeatedly in the embodiment of the present invention. 
     The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. 
     It is easy for those skilled in the art to think that: any combination application of the above-mentioned various embodiments is feasible, so any combination of the above-mentioned various embodiments is the embodiment of the present disclosure, but the present specification will not detail those herein one by one due to length limit. 
     In the specification provided herein, a lot of specific details are explained. However, it can be understood that the embodiments of the present disclosure can be practiced without these specific details. In some instances, well-known methods, structures and technologies are not shown in detail, so as not to obscure the understanding of this specification. 
     Similarly, it should be understood that in order to simplify the present disclosure and help understanding one or more of the various aspects of the embodiments of the present disclosure, in the above description of the exemplary embodiments of the present disclosure, the various features of the present disclosure are sometimes grouped together into a single embodiment, figure, or description thereof. However, the disclosed method should not be interpreted as reflecting the intention that the claimed disclosure requires more features than those explicitly stated in each claim. More precisely, as reflected in the claims, the aspect of the present invention lies in that it is possible to use features less than all the features of a single embodiment disclosed above. Therefore, the claims following the specific embodiment are thus explicitly incorporated into the specific embodiment, wherein each claim itself serves as a separate embodiment of the present disclosure. 
     Those skilled in the art can understand that it is possible to adaptively change the modules in the device in the embodiment and set them in one or more devices different from the embodiment. The modules or units or components in the embodiments can be combined into one module or unit or component, and in addition, they can be divided into multiple sub-modules or sub-units or sub-components. Except that at least some of such features and/or processes or units are mutually exclusive, any combination can be used to combine all the features disclosed in this specification (comprising the accompanying claims, abstract and drawings) and all processes or units of any method or device disclosed in this way. Unless expressly stated otherwise, each feature disclosed in this specification (comprising the accompanying claims, abstract and drawings) may be replaced by an alternative feature providing the same, equivalent or similar purpose. 
     In addition, those skilled in the art can understand that although some embodiments described herein comprise certain features comprised in other embodiments but not other features, the combination of features of different embodiments means to be within the scope of the present disclosure and form different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination. 
     It should be noted that the above-mentioned embodiments illustrate the present disclosure, rather than limiting the present disclosure and those skilled in the art can design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference numerals placed between parentheses should not be constructed as a limitation to the claims. The word “comprising” does not exclude the presence of elements or steps not listed in the claims. The word “a” or “an” preceding an element does not exclude the presence of multiple such elements. The present disclosure can be realized by means of hardware comprising several different elements and by means of a suitably programmed computer. In the unit claims enumerating several devices, several of these devices may be embodied in the same hardware item. The use of the words first, second, and third, etc. do not indicate any order. These words can be interpreted as names.
