[0060] As described in the background, the existing sorting platform is usually a single-sided double-station sorting platform. When the above sorting platform is used to sort goods, there is a problem of small flow of material boxes and low sorting efficiency. The inventor found that the reason for the above problem is that the existing sorting platform includes two carrier frames arranged side by side and a transmission mechanism arranged on the two carrier frames. The transmission mechanism is used to transfer the material boxes and form a first sorting line and a second sorting line. A transfer mechanism is arranged between the first sorting line and the second sorting line to transfer the material boxes between the first sorting line and the second sorting line. The first sorting line and the second sorting line are located at the same height and share a sorting inlet and a sorting outlet.

[0061] However, the loading machine and the unloading machine have double-layer inlets and outlets. If the sorting platform only has one sorting inlet and one sorting outlet, the maximum utilization of the loading machine and the unloading machine cannot be achieved. Further, the material boxes are prone to congestion on the sorting platform, resulting in small flow of material boxes and low sorting efficiency of the sorting platform.

[0062] To solve the above technical problems, the present disclosure provides a sorting platform, a sorting system and a sorting method, wherein the sorting platform comprises a bearing frame and a transmission mechanism arranged on the bearing frame, the transmission mechanism is used to move the material box on the bearing frame, and forms a first sorting line and a second sorting line. The first sorting line comprises a first sorting inlet, a second sorting outlet and a first sorting position between the two; the second sorting line comprises a second sorting inlet, a second sorting outlet and a second sorting position between the two.

[0063] The first sorting inlet is arranged below the second sorting inlet, and the first sorting outlet is arranged above the second sorting outlet, so that the sorting platform comprises two sorting inlets at different heights and two sorting outlets at different heights; the sorting platform is arranged in this way to provide a double-layer sorting line matched with a double-layer box supply of the unloading machine and the feeding machine, to realize the maximum utilization rate of the unloading machine and the feeding machine, and to avoid congestion of the material box when moving on the sorting platform, so as to improve the flow and sorting efficiency of the material box.

[0064] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all.

The feeding machine 500 includes a double-layer arranged first feeding port and a second feeding port, and the first feeding port is located above the second feeding port. When the feeding machine 500 works, two sorted containers can be transferred to the feeding machine 500 from the first feeding port and the second feeding port at the same time, and the sorted containers are further transferred to the storage rack by the storage robot.

[0072] The sorting platform 100 provided by the embodiment of the present disclosure includes a bearing frame 101 and a transmission mechanism 102. In the second direction, the bearing frame 101 includes opposite first and second sides, wherein the first side is the side of the bearing frame 101 close to the seeding wall, and the second side is the side of the bearing frame 101 away from the seeding wall. In the first direction, the bearing frame 101 includes opposite left and right ends.

[0073] The transmission mechanism 102 is arranged on the carrier frame 101, and the transmission mechanism 102 is used to drive the movement of the box on the carrier frame 101, so that the box from the unloading machine 400 can be moved from the sorting inlet to the corresponding sorting position, and the sorted box can be moved to the sorting outlet and transferred to the feeding machine 500.

[0074] The transmission mechanism 102 includes a first sorting line 10 and a second sorting line 20, the first sorting line 10 includes a first sorting inlet and a first sorting outlet; along the second direction, the first sorting inlet and the first sorting outlet are arranged on the second side of the carrier frame 101, and along the first direction, the first sorting inlet and the first sorting outlet are respectively located at the left and right ends of the carrier frame 101. The first sorting position 16 is arranged between the first sorting inlet and the first sorting outlet, that is, the box to be sorted enters the first sorting line 10 from the first sorting inlet, and after sorting through the first sorting position 16, it can be moved out of the first sorting line 10 from the first sorting outlet.

[0075] The second sorting line 20 includes a second sorting inlet and a second sorting outlet, wherein the second sorting position 26 is arranged between the second sorting inlet and the second sorting outlet, the second sorting inlet is located on the same side of the carrier frame 101 as the first sorting inlet, and the first sorting inlet is located below the second sorting inlet; the second sorting outlet is located on the same side of the carrier frame 101 as the first sorting outlet, and the second sorting outlet is located below the first sorting outlet.

[0076] In other words, the first sorting line 10 is provided with an uphill to make the first sorting inlet and the first sorting outlet located at different heights, and the second sorting line 20 is provided with a downhill to make the second sorting inlet and the second sorting outlet located at different heights.

[0077] On the basis of the above-mentioned embodiment, the sorting system provided by the embodiment of the present disclosure further includes a server, the server is in signal connection with the unloading machine 400 and the feeding machine 500, and the server is configured to determine the box to be sorted according to the goods order information, to determine the sorting position information of the box, and to send instructions to the unloading machine 400 and the feeding machine 500; the unloading machine 400 is configured to transfer the box to the corresponding sorting line after receiving the instructions, and the feeding machine 500 is configured to make the sorted box return to the warehouse through the feeding machine 500 after receiving the instructions.

[0078] Specifically, when the sorting system provided by the embodiment of the present disclosure is used to sort goods, the server sends instructions to the unloading machine 400 and the feeding machine 500, the first unloading port of the unloading machine 400 is opposite to the first sorting inlet, so that the box guided from the first unloading port enters the first sorting line 10 through the first sorting inlet for sorting. The second unloading port of the unloading machine 400 is opposite to the second sorting inlet, so that the box guided from the second unloading port enters the second sorting line 20 through the second sorting inlet for sorting.

[0079] The first feeding port of the feeding machine 500 is connected with the first sorting outlet of the sorting platform 100, so that the bin sorted by the first sorting position 16 flows out from the first sorting outlet and is transferred to the feeding machine 500, and then is returned to the warehouse. The second feeding port is connected with the second sorting outlet of the sorting platform 100, so that the bin sorted by the second sorting position 26 flows out from the second sorting outlet and is transferred to the feeding machine 500, and then is returned to the warehouse.

[0080] Compared with the prior art that the first sorting line 10 and the second sorting line 20 are located at the same height and share one sorting inlet and one sorting outlet, the sorting system provided by the embodiment of the present disclosure includes two sorting inlets located at different heights and two sorting outlets located at different heights, so that a double-layer sorting line cooperating with the double-layer bin supply of the unloading machine 400 and the feeding machine 500 can be provided, the maximum utilization rate of the unloading machine 400 and the feeding machine 500 can be realized, and the congestion phenomenon of the bin when moving in the sorting platform 100 can be avoided, so as to improve the flow and sorting efficiency of the bin.

[0081] Further, along the second direction, the first sorting position 16 and the second sorting position 26 can be arranged on the same side of the carrier frame 101, and the first sorting line 10 and the second sorting line 20 can make the first sorting position 16 and the second sorting position 26 located at the same height by climbing and descending slopes; in this way, the sorting comfort of the sorting personnel, the smoothness of the operation process, and the reasonable arrangement of the sowing wall can be ensured, so as to improve the sorting efficiency.

[0082] It should be noted that, in order to further improve the sorting efficiency of the sorting system, the sorting system in the embodiment of the present disclosure further includes an auxiliary component connected with a server, the auxiliary component includes a display, a code scanner and a code reader, wherein each bin is provided with at least one label, and the label can be recognized by the code scanner and the code reader.

[0083] For example, the first sorting position 16 and the second sorting position 26 are each provided with a display and a code scanner, wherein the display is connected with the code scanner, when the bin moves to the first sorting position 16 or the second sorting position 26, the sorting personnel uses the code scanner (for example, the code scanner can be a code scanner gun) to recognize the label of the bin, the information of the goods to be sorted in the bin is displayed in the display, and the sorting personnel can quickly sort the goods in the bin according to the information of the goods to be sorted; in this way, the sorting efficiency can be improved.

[0084] The first sorting line 10 and the second sorting line 20 formed by the transmission mechanism 102 in the embodiment of the present disclosure include multiple sections, so that the bin has different moving paths when moving on the transmission mechanism 102; the first sorting line 10 and the second sorting line 20 provided by the embodiment of the present disclosure are described in detail as follows.

[0085] Referring to Figure 2 and Figure 3 In the direction from the first sorting inlet to the first sorting outlet, the first sorting line 10 comprises, in sequence, a first leading-in section 11, a first conveying section 12, a second conveying section 13, a climbing section 14, and a first leading-out section 15. The first leading-in section 11 is connected to one end of the first conveying section 12, and the two form a right angle structure. The other end of the first leading-in section 11 forms the first sorting inlet, and the first leading-in section 11 is arranged in cooperation with the first unloading port of the unloading machine 400. The first sorting inlet and the first unloading port are at the same height, so that the to-be-sorted container enters the first leading-in section 11 from the first sorting inlet, i.e., the first leading-in section 11 is used to guide the container to the first sorting line 10.

[0086] Further, one end of the first leading-out section 15 is connected to one end of the climbing section 14, and the two form a right angle structure. The other end of the first leading-out section 15 forms the first sorting outlet, and the first leading-out section 15 is arranged in cooperation with the first loading port of the loading machine 500. The first sorting outlet and the first loading port are at the same height, so that the to-be-sorted container is transferred from the first leading-out section 15 and the first sorting outlet to the loading machine 500, i.e., the first leading-out section 15 is used to guide the container out of the first sorting line 10.

[0087] The first conveying section 12, the second conveying section 13, and the climbing section 14 are located between the first leading-in section 11 and the first leading-out section 15. In the second direction, the first conveying section 12 is located on one side of the second conveying section 13, i.e., the first conveying section 12 and the second conveying section 13 form a right angle structure. When the container moves in the first conveying section 12, it needs to move laterally (exemplarily, the lateral movement in the embodiment of the present disclosure refers to the movement of the container in the second direction), so as to be transferred to the second conveying section 13.

[0088] The length direction of the first conveying section 12 and the second conveying section 13 extends along the first direction. One end of the first conveying section 12, which is away from the first leading-in section 11, is used to connect the second conveying section 13. The second conveying section 13 and the climbing section 14 are located on the same side of the first conveying section 12, and along the first direction, the projection of the first conveying section 12 and the climbing section 14 on the same plane is located on the same straight line.

[0089] On the basis of the above embodiment, the first sorting position 16 is formed on the first conveying section 12. The transmission mechanism 102 has a plurality of transmission rollers on the first conveying section 12. The plurality of transmission rollers are arranged at intervals along the first direction, and the transmission rollers have a power source, which can drive the container to move on the first conveying section 12.

[0090] Further, in order to facilitate the sorting personnel to sort the material box, the plurality of transmission rollers on the first conveying section 12 are all arranged in an inclined manner, and the height of one end of the transmission roller towards the seeding wall is lower than that of the other end in the second direction, so that when the material box moves on the first conveying section 12, the box opening of the material box can be inclined outward, which can facilitate the sorting personnel to sort the goods in the material box and improve the sorting efficiency.

[0091] The transmission mechanism 102 in the embodiment of the present disclosure further includes a first transfer mechanism and a second transfer mechanism, wherein the first transfer mechanism and the second transfer mechanism are used to change the moving direction of the material box. The first transfer mechanism is arranged at one end of the first conveying section 12 close to the second conveying section 13, i.e., the first transfer mechanism is arranged at the right angle structure formed between the first conveying section 12 and the second conveying section 13.

[0092] The first transfer mechanism is used to transfer the material box from the first conveying section 12 to the second conveying section 13. For example, the first transfer mechanism can be a jacking transfer mechanism, when the material box moves to the position of the jacking transfer mechanism, the jacking transfer mechanism acts and provides a lateral force to the material box, the direction of the lateral force is from the first side of the carrier frame to the second side, so that the material box can move from the first conveying section 12 to the second conveying section 13 under the action of the lifting force.

[0093] After the material box is sorted by the first sorting position 16 and transferred to the second conveying section 13 through the first transfer mechanism, the transmission mechanism 102 is provided with a plurality of transmission rollers on the second conveying section 13, and the transmission rollers have a power source capable of driving the material box to move on the second conveying section 13, so that the material box can move to the climbing section 14 and be moved out of the first sorting line 10 through the first guide-out section 15.

[0094] The first guide-out section 15 and the second conveying section 13 are located at different heights, and the material box is lifted from the second conveying section 13 to the first guide-out section 15 through the climbing section 14. Specifically, the climbing section 14 can be provided with a first transmission belt, and the first transmission belt is configured with a power source capable of driving the material box to climb to lift the material box from the height of the second conveying section 13 to the height of the first guide-out section 15.

[0095] An adapter section is arranged between the first guide-out section 15 and the climbing section 14, and the adapter section can be regarded as a horizontal extension of the climbing section 14. Since the climbing section 14 and the first guide-out section 15 form a right angle structure, the material box needs to be moved laterally at this position through the second transfer mechanism.

[0096] The second transfer mechanism is arranged at one end of the first guide-out section 15 close to the climbing section 14, and is used to change the moving direction of the bin, so as to move the bin from the climbing section 14 to the first guide-out section 15. Further, the second transfer mechanism can be a right-angle transfer mechanism, which includes a plurality of rollers for turning, wherein the rollers arranged close to the climbing section rotate in the same direction as the moving direction of the bin on the climbing section 14; the rollers arranged close to the first guide-out section 15 rotate in the same direction as the moving direction of the bin on the first guide-out section 15. When the bin moves to the second transfer mechanism, the bin can be moved from the climbing section 14 to the first guide-out section 15 under the action of the second transfer mechanism, so as to be moved out of the first sorting line 10.

[0097] Referring to Figure 2 and Figure 4 , in the direction from the second sorting inlet to the second sorting outlet, the second sorting line 20 includes a second guide-in section 21, a third transmission section 22, a downhill section 23, a fourth transmission section 24 and a second guide-out section 25 arranged in sequence; wherein the second guide-in section 21 is located above the first guide-in section 11, one end of the second guide-in section 21 is connected with one end of the third transmission section 22, and a right-angle structure is formed between the two. The other end of the second guide-in section 21 forms the second sorting inlet, and the second guide-in section 21 is arranged in cooperation with a second unloading port of the unloading machine 400, the second unloading port and the second sorting inlet are at the same height, so that the bin to be sorted enters the second guide-in section 21 from the second sorting inlet, that is, the second guide-in section 21 is used to guide the bin to the second sorting line 20.

[0098] The second guide-out section 25 is located below the first guide-out section 15, one end of the second guide-out section 25 is connected with one end of the fourth transmission section 24, and a right-angle structure is formed between the two; the other end of the second guide-out section 25 forms the second sorting outlet, and the second guide-out section 25 is arranged in cooperation with a second feeding port of the feeding machine 500, the second feeding port and the second sorting outlet are at the same height, so that the bin to be sorted is transferred from the second guide-out section 25 and the second sorting outlet to the feeding machine 500, that is, the second guide-out section 25 is used to guide the bin out of the second sorting line 20.

[0099] The third transmission section 22, the downhill section 23 and the fourth transmission section 24 are arranged between the second guide-in section 21 and the second guide-out section 25, along the second direction, the third transmission section 22 is arranged on one side of the first transmission section 12, that is, the third transmission section 22 is arranged on the same side as the second transmission section 13. The fourth transmission section 24 and the downhill section 23 are located on the same side of the third transmission section 22, and along the first direction, the projection of the fourth transmission section 24 and the downhill section 23 on the plane is located on the same straight line.

[0100] Further, the third conveying section 22 is located at a different height from the first conveying section 12, for example, the third conveying section 22 is located above the first conveying section 12, and the third conveying section 22 is away from one end of the second leading-in section 21 for connecting with the downhill section 23, and the downhill section 23 is connected with the fourth conveying section 24, so that the height of the fourth conveying section 24 can be reduced.

[0101] Based on the above embodiment, the transmission mechanism 102 is provided with a plurality of transmission rollers on the third conveying section 22, the plurality of transmission rollers are horizontally and interval arranged along the first direction, and the transmission rollers have a power source to drive the material box to move on the third conveying section 22. The third conveying section 22 and the downhill section 23 form a right angle structure, and the material box needs to move laterally when moving to the end of the third conveying section 22, so as to transfer the material box from the third conveying section 22 to the downhill section 23.

[0102] For example, a right angle transfer mechanism is arranged between the third conveying section 22 and the downhill section 23, when the material box moves to the right angle transfer mechanism at the end of the third conveying section 22, the moving direction of the material box can be changed by the right angle transfer mechanism, so as to move the material box from the third conveying section 22 to the downhill section 23.

[0103] The transmission mechanism 102 is provided with a plurality of transmission rollers on the downhill section 23, the transmission rollers can be unpowered transmission rollers, and the plurality of transmission rollers are interval arranged and form a guide slope, and the material box can move from the downhill section 23 to the fourth conveying section 24 under the action of gravity. It can be understood that the transmission mechanism 102 can also be provided with a second transmission belt on the downhill section 23, which is not limited in the embodiment.

[0104] The second picking position 26 is formed on the fourth conveying section 24, and the transmission mechanism 102 is provided with a plurality of transmission rollers on the fourth conveying section 24, the plurality of transmission rollers are horizontally and interval arranged along the first direction, and the transmission rollers have a power source to drive the material box to move on the first conveying section 12.

[0105] Since the fourth conveying section 24 and the second leading-out section 25 form a right angle structure, the material box needs to move laterally when moving to the end of the fourth conveying section 24, and the right angle transfer mechanism is arranged between the fourth conveying section 24 and the second leading-out section 25, and the moving direction of the material box is changed by the right angle transfer mechanism, so as to move the material box from the fourth conveying section 24 to the second leading-out section 25, thereby moving the material box out of the second sorting line 20.

[0106] It should be noted that in the sorting platform 100 in the embodiment of the present disclosure, the first leading-in section 11, the first conveying section 12, the second conveying section 13, the fourth conveying section 24 and the second leading-out section 25 can be located at the same height; the second leading-in section 21, the third conveying section 22 and the first leading-out section 15 can be located at the same height.

[0107] In this way, the first sorting position 16 of the first sorting line 10 and the second sorting position 26 of the second sorting line 20 are at the same height, facilitating the sorting personnel to sort the goods, and the first sorting inlet and the second sorting outlet are at the same height, and the second sorting inlet and the first sorting outlet are at the same height, facilitating the unloading machine 400 to transfer the box to the sorting platform 100 and transfer the sorted box to the loading machine 500, thereby improving the sorting efficiency.

[0108] In other embodiments, a transfer mechanism is arranged between the first sorting line 10 and the second sorting line 20, so that the box moving on the first sorting line 10 can be transferred to the second sorting line 20. For example, the transmission mechanism 102 further comprises a third transfer mechanism arranged on the second transmission section 13, and the third transfer mechanism is opposite to the fourth transmission section 24, and the third transfer mechanism is used to transfer the box from the second transmission section 13 to the fourth transmission section 24.

[0109] For example, the third transfer mechanism can be a jacking transfer mechanism, which can be arranged in the same way as the first transfer mechanism, which will not be described here. When the box moves to the third jacking transfer mechanism on the second transmission section 13, the third jacking transfer mechanism acts and provides a lateral force to the box, so that the box moves from the second transmission section 13 to the fourth transmission section 24, thereby realizing the transfer of the box from the first sorting line 10 to the second sorting line 20.

[0110] If the sorting path of the box needs to pass through the first sorting position 16 and the second sorting position 26, the box enters the first guide-in section 11, the first transmission section 12 from the first sorting inlet, and after being sorted by the first sorting position 16, it enters the second transmission section 13 through the first transfer mechanism. When the box passes through the third transfer mechanism, the third transfer mechanism transfers the box to the fourth transmission section 24 of the second sorting line 20, and after being sorted by the second sorting position 26, the box can be moved out of the second sorting line 20.

[0111] Further, referring to Figure 1 and Figure 4 The fourth transmission section 24 of the embodiment of the present disclosure further comprises an abnormal box outlet 27, and the fourth transmission section 24 further comprises a fourth transfer mechanism arranged at the abnormal box outlet 27, and the fourth transfer mechanism is configured to transfer the abnormal box from the fourth transmission section 24 to the abnormal box outlet 27, and then move out of the first sorting line 10 and / or the second sorting line 20.

[0112] For example, the abnormal box outlet 27 can be arranged on the fourth transmission section 24 and away from the second sorting position 26. The fourth transfer mechanism can be a jacking transfer mechanism, and when the abnormal box moves to the jacking transfer mechanism, the jacking transfer mechanism acts and provides a lateral force to the abnormal box, and the abnormal box moves to the abnormal box outlet 27 under the action of the lateral force.

[0113] Preferably, the abnormal bin outlet 27 can be arranged at the end of the fourth conveying section 24 and opposite to the second leading-out section 25. In this way, a transfer mechanism can be arranged at the end of the fourth conveying section 24, and the normal bins can be controlled to move from the fourth conveying section 24 to the second leading-out section 25, or the abnormal bins can be controlled to move from the fourth conveying section to the abnormal bin outlet 27. In this way, the manufacturing cost of the sorting platform can be saved, and the layout thereof can be optimized.

[0114] It should be noted that the abnormal bin can be a bin from the first sorting line 10, and the label of the bin cannot be recognized by the code reader arranged on the first sorting line 10. If the bin is determined to be an abnormal bin, when the abnormal bin passes through the third transfer mechanism, the third transfer mechanism can transfer the bin from the second conveying section 13 of the first sorting line 10 to the fourth conveying section 24 of the second sorting line 20; further, when the bin passes through the fourth transfer mechanism, the fourth transfer mechanism transfers the bin to the abnormal bin outlet 27, so as to move the abnormal bin out of the sorting platform 100.

[0115] In this way, the abnormal bin can be moved out of the sorting platform 100 from the abnormal bin outlet 27, so as to avoid congestion of the bins on the sorting platform, further improve the flow of the bins on the sorting platform 100, and improve the sorting efficiency.

[0116] It should be noted that, in the first transfer mechanism, the second transfer mechanism, the third transfer mechanism and the fourth transfer mechanism in the embodiment, the first transfer mechanism, the third transfer mechanism and the fourth transfer mechanism are jacking transfer mechanisms, and the second transfer mechanism is a right-angle transfer mechanism, which is only an example of the specific implementation scheme of the embodiment and does not represent a limitation. For example, according to the turning requirement of the bin on the first sorting line 10 and the second sorting line 20 and in combination with the arrangement space of the two turning positions, a jacking transfer mechanism or a right-angle transfer mechanism can be selectively arranged at each turning position.

[0117] Embodiment Two

[0118] As shown in FIG. 1, the sorting method provided by the embodiment of the present disclosure is based on the sorting system in Embodiment One, and includes the following steps: Figure 5

[0119] Step S100: determining the sorting position corresponding to the sorting bin.

[0120] ​Specifically, the sorting system obtains the to-be-picked order information of goods, and transmits the order information of goods to the server of the sorting system. The server determines the picking position of the to-be-picked order of goods according to the order information of goods, and further determines the picking position corresponding to the to-be-picked bin corresponding to the to-be-picked order of goods. For example, the picking position of the to-be-picked bin is the first picking position 16 and / or the second picking position 26.

[0121] Step S200: determining the target unloading port corresponding to the to-be-picked bin according to the picking position.

[0122] Specifically, after the server of the sorting system determines the picking position of the to-be-picked bin according to the order information of goods, the target unloading port corresponding to the picking position is determined. The target unloading port includes a first unloading port and a second unloading port. The first unloading port can be connected with the first sorting inlet of the first sorting line 10, and the to-be-picked bin is transmitted to the first picking position 16 and / or the second picking position 26. The second unloading port can be connected with the second sorting inlet of the second sorting line 20, and the to-be-picked bin is transmitted to the second picking position 26.

[0123] It should be noted that when the target unloading port of the to-be-picked bin is determined, the target loading port of the sorted bin is also determined accordingly. For example, if the target unloading port is the first unloading port, the corresponding target unloading port is the first loading port.

[0124] For example, when the picking position is the first picking position 16, the target unloading port of the to-be-picked bin is determined to be the first unloading port, and the target loading port of the sorted bin is the first loading port of the loading machine 500. The first unloading port and the first loading port correspond to the first sorting line 10 respectively. The first sorting inlet of the first sorting line 10 is connected with the first unloading port, and the first sorting outlet is connected with the first loading port.

[0125] For example, when the picking position is the first picking position 16, the moving route of the bin on the first sorting line 10 is: entering the first sorting line 10 through the first sorting inlet, and sequentially passing through the first guide-in section 11, the first transmission section 12, the second transmission section 13, the climbing section 14 and the first guide-out section 15, and moving out of the first sorting line 10 through the first sorting outlet, so that the bin completes the sorting of the first picking position 16.

[0126] In another embodiment, when the picking position is the second picking position 26, the target unloading port of the to-be-picked bin is determined to be the second unloading port. The target loading port of the sorted bin is the second loading port of the loading machine 500. The second unloading port and the second loading port correspond to the second sorting line 20 respectively. The second sorting inlet of the second sorting line 20 is connected with the second unloading port, and the second sorting outlet is connected with the second loading port.

[0127] For example, when the sorting position is the second sorting position 26, the determined moving route of the bin on the second sorting line 20 is: entering the second sorting line 20 through the second sorting inlet, and sequentially passing through the second guide-in section 21, the third conveying section 22, the downhill section 23, the fourth conveying section 24 and the first guide-out section 15, and moving out of the second sorting line 20 through the second sorting outlet, so that the bin completes the sorting of the second sorting position 26.

[0128] In another embodiment, when the sorting position is the first sorting position 16 and the second sorting position 26, it is determined that the target unloading port of the bin to be sorted is the first unloading port, and the target loading port corresponding to the sorted bin is the second loading port, wherein the first unloading port is docked with the first sorting inlet of the first sorting line 10, and the second loading port is docked with the second sorting outlet of the second sorting line 20.

[0129] For example, when the sorting position is the first sorting position 16 and the second sorting position 26, the determined moving route of the bin is: entering the first sorting line 10 through the first sorting inlet, and sequentially passing through the first guide-in section 11, the first conveying section 12 and the second conveying section 13, and entering the second sorting line 20 from the second conveying section 13 through the third transfer mechanism.

[0130] The moving route on the second sorting line 20 is: sequentially passing through the fourth conveying section 24 and the second guide-out section 25, and moving out of the second sorting line 20 through the second sorting outlet, so that the bin completes the sorting of the first sorting position 16 and the second sorting position 26; that is, when the sorting position is the first sorting position 16 and the second sorting position 26, the running route of the bin to be sorted is sequentially passing through the first guide-in section 11, the first conveying section 12, the second conveying section 13, the third transfer mechanism, the fourth conveying section 24 and the second guide-out section 25.

[0131] Step S300: controlling the unloading machine 400 to convey the bin to be sorted to the sorting inlet corresponding to the target unloading port through the target unloading port.

[0132] Specifically, the unloading machine 400 is configured to, according to the instruction, oppositely arrange the target unloading port and the corresponding sorting inlet, so as to convey the bin to the corresponding sorting inlet through the target unloading port, thereby enabling the bin to move to the corresponding sorting position according to the set running route.

[0133] On the basis of the above-mentioned embodiments, the sorting method provided by the embodiments of the present disclosure further comprises:

[0134] When the to-be-picked bin is picked at the first picking position 16, whether the to-be-picked bin is the bin corresponding to the second picking position 26 is determined according to the reading result of the code reader on the second conveying section 13, and the bin is controlled to continue moving along the first picking line 10 or is transferred to the second picking position 26 of the second picking line 20 for picking according to the determination result. In this way, compared with the bin needing to enter two different picking positions from two picking ports respectively, the bin only needs to enter the picking port once in the embodiment of the disclosure, the bin can be picked at the first picking position 16 and the second picking position 26, and the picking efficiency of the bin is improved.

[0135] Specifically, when the to-be-picked bin is picked at the first picking position 16, the bin can enter the second conveying section 13 through the first transfer mechanism, the second conveying section 13 is provided with a code reader, the label of the bin can be identified by using the code reader, and whether the bin needs to be picked at the second picking position 26 is determined according to the reading result of the code reader.

[0136] When the bin needs to be picked at the second picking position 26, when the bin moves to the third transfer mechanism, the third transfer mechanism acts, the bin is transferred from the second conveying section 13 to the fourth conveying section 24, the bin continues to move on the fourth conveying section 24, is picked at the second picking position 26, and is moved out of the picking platform 100 from the second picking outlet, and is returned to the warehouse through the feeding machine 500.

[0137] When the bin does not need to be picked at the second picking position 26, the bin needs to continue to move along the first picking line 10, that is, the bin needs to pass through the second conveying section 13, the climbing section 14 and the first leading-out section 15 in turn, and is moved out of the picking platform 100 from the first picking outlet and is returned to the warehouse through the feeding machine 500.

[0138] The picking method provided in the embodiment of the disclosure further includes identifying the label of the bin by using the code reader, if the code reader cannot identify the label of the bin, determining that the bin is an abnormal bin, and controlling the bin to be transported to the abnormal bin outlet 27. In this way, the abnormal bin can be moved out of the picking platform 100 from the abnormal bin outlet 27, the congestion phenomenon of the bin moving on the picking platform can be avoided, the flow of the bin on the picking platform 100 is further improved, and the picking efficiency is improved.

[0139] Specifically, a plurality of code readers are arranged on the first sorting line 10 and the second sorting line 20, and the plurality of code readers are arranged on the first sorting line 10 and the second sorting line 20 at intervals, respectively. The abnormal bin outlet 27 is arranged on the fourth conveying section 24 of the second sorting line 20. For the bins located on the second sorting line 20, the code readers arranged between the second sorting inlet and the abnormal bin outlet 27 can be used to identify the labels of the bins, and determine whether the bins are abnormal bins. If the bins are abnormal bins, when the abnormal bins move to the fourth transfer mechanism of the fourth conveying section 24, the fourth transfer mechanism acts and can transport the abnormal bins to the abnormal bin outlet 27.

[0140] Further, for the bins located on the first sorting line 10, the code readers arranged between the first sorting inlet and the third transfer mechanism can be used to identify the labels of the bins, for example, the code readers arranged on the first conveying section can be used to identify the labels of the bins, and determine whether the bins are abnormal bins. If the bins are abnormal bins, when the abnormal bins move to the third transfer mechanism, the third transfer mechanism acts and can transfer the abnormal bins from the second conveying section to the fourth conveying section, and the abnormal bins continue to move on the fourth conveying section. When the abnormal bins move to the fourth transfer mechanism of the fourth conveying section 24, the fourth transfer mechanism acts and can transport the abnormal bins to the abnormal bin outlet 27.
