The loader 500 is used to receive the material boxes sorted by the sorting platform 100, transfer the material boxes to the storage robot, and return the sorted material boxes to the warehouse through the storage robot. The loader 500 includes a first loading port and a second loading port arranged in double layers, and the first loading port is located above the second loading port; when the loader 500 is working, two sorted material boxes can be transferred from the first loading port and the second loading port to the loader 500 at the same time, and the sorted material boxes can be further transferred to the transfer storage shelf through the storage robot.

The sorting platform 100 provided in the disclosed embodiment includes a support frame 101 and a transmission mechanism 102. Along the second direction, the support frame 101 includes a first side and a second side opposite to each other, wherein the first side is a side of the support frame 101 close to the sowing wall, and the second side is a side of the support frame 101 away from the sowing wall; along the first direction, the support frame 101 includes two opposite left and right ends.

The transmission mechanism 102 is arranged on the support frame 101. The transmission mechanism 102 is used to drive the material box to move on the support frame 101, so that the material box from the unloader 400 can move from the sorting entrance to the corresponding sorting position, and the sorted material box can move to the sorting exit and transfer to the loader 500.

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 respectively arranged at the second side of the support frame 101, and along the first direction, the first sorting inlet and the first sorting outlet are respectively arranged at the left and right ends of the support frame 101. The first sorting position 16 is arranged between the first sorting inlet and the first sorting outlet, that is, the material box to be sorted enters the first sorting line 10 from the first sorting inlet, and after being sorted by the first sorting position 16, it can be moved out of the first sorting line 10 from the first sorting outlet.

The second sorting line 20 includes a second sorting entrance and a second sorting outlet, wherein the second sorting position 26 is arranged between the second sorting entrance and the second sorting outlet, the second sorting entrance and the first sorting entrance are located on the same side of the support frame 101, and the first sorting entrance is located below the second sorting entrance; the second sorting outlet and the first sorting outlet are located on the same side of the support frame 101, and the second sorting outlet is located below the first sorting outlet.

In other words, an upslope is provided in the first sorting line 10 so that the first sorting entrance and the first sorting exit are located at different heights, and a downslope is provided in the second sorting line 20 so that the second sorting entrance and the second sorting exit are located at different heights.

On the basis of the above-mentioned embodiments, the sorting system provided by the disclosed embodiment further includes a server, which is connected to the unloader 400 and the loader 500 by signal, and the server is configured to determine the material box to be selected according to the cargo order information, so as to determine the selection position information of the material box, and send instructions to the unloader 400 and the loader 500; the unloader 400 is configured to transfer the material box to the sorting line corresponding to the material box after receiving the instruction, and the loader 500 is configured to return the sorted material box to the warehouse through the loader 500 after receiving the instruction.

Specifically, when the sorting system provided by the disclosed embodiment is used to sort goods, the server sends instructions to the unloader 400 and the loader 500, and the first unloading port of the unloader 400 is opposite to the first sorting entrance, so that the material box discharged from the first unloading port enters the first sorting line 10 through the first sorting entrance for sorting. The second unloading port of the unloader 400 is opposite to the second sorting entrance, so that the material box discharged from the second unloading port enters the second sorting line 20 through the second sorting entrance for sorting.

The first loading port of the loader 500 is connected to the first sorting outlet of the sorting platform 100, so that the material box after sorting at the first sorting position 16 flows out from the first sorting outlet and is transferred to the loader 500, and then returns to the warehouse. The second loading port is connected to the second sorting outlet of the sorting platform 100, so that the material box after sorting at the second sorting position 26 flows out from the second sorting outlet and is transferred to the loader 500, and then returns to the warehouse.

Compared with the prior art solution in which the first sorting line 10 and the second sorting line 20 are located at the same height and share a sorting entrance and a sorting exit, the sorting system provided by the disclosed embodiment includes a sorting platform 100 including two sorting entrances and two sorting exits located at different heights, so that a double-layer sorting line can be provided to cooperate with the double-layer supply box of the unloader 400 and the loader 500, and the maximum utilization rate of the unloader 400 and the loader 500 can be achieved, and the congestion of the material box when the sorting platform 100 moves can be avoided, so as to improve the flow rate and picking efficiency of the material box.

Furthermore, along the second direction, the first picking position 16 and the second picking position 26 can be arranged on the same side of the support frame 101, and the first sorting line 10 and the second sorting line 20 can be arranged at the same height by climbing and descending the slope; such a setting ensures the picking comfort of the sorting personnel, the smoothness of the operation process, and facilitates the reasonable layout of the sowing wall, thereby improving the picking efficiency.

It should be noted that in order to further improve the sorting efficiency of the sorting system, the sorting system in the disclosed embodiment also includes an auxiliary element connected to the server signal, and the auxiliary element includes a display, a scanner and a reader, wherein each material box is equipped with at least one label, and the label can be identified by the scanner and the reader.

For example, the first picking position 16 and the second picking position 26 are both provided with a display and a scanner, wherein the display is connected to the scanner signal. When the material box moves to the first picking position 16 or the second picking position 26, the sorter uses the scanner (for example, the scanner can be a barcode gun) to identify the label of the material box, and the information of the goods to be picked in the material box is displayed on the display. The sorter can quickly sort the goods in the material box according to the information of the goods to be picked; such a setting can improve the sorting efficiency.

The first sorting line 10 and the second sorting line 20 formed by the transmission mechanism 102 of the disclosed embodiment include multiple sections so that the material box 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 disclosed embodiment are described in detail as follows.

Referring to Figures 2 and 3, along the direction from the first sorting entrance to the first sorting exit, the first sorting line 10 includes a first introduction section 11, a first transmission section 12, a second transmission section 13, a climbing section 14 and a first export section 15 arranged in sequence; wherein one end of the first introduction section 11 is connected to one end of the first transmission section 12, and a right angle structure is formed between the two; the other end of the first introduction section 11 forms the first sorting entrance, and the first introduction section 11 is arranged in coordination with the first discharge port of the discharger 400, and the first sorting entrance and the first discharge port are located at the same height, so that the material box to be sorted enters the first introduction section 11 from the first sorting entrance, that is, the first introduction section 11 is used to lead the material box to the first sorting line 10.

Furthermore, one end of the first export section 15 is connected to one end of the climbing section 14, and a right angle structure is formed between the two; the other end of the first export section 15 forms a first sorting outlet, and the first export section 15 is arranged in coordination with the first loading port of the feeder 500, and the first sorting outlet and the first loading port are located at the same height, so that the material box to be sorted is transferred from the first export section 15 and the first sorting outlet to the feeder 500, that is, the first export section 15 is used to lead the material box out of the first sorting line 10.

The first transmission section 12, the second transmission section 13, and the climbing section 14 are located between the first inlet section 11 and the first outlet section 15. Along the second direction, the first transmission section 12 is located on one side of the second transmission section 13, that is, a right-angle structure is formed between the first transmission section 12 and the second transmission section 13. When the material box moves in the first transmission section 12, it needs to move sideways (for example, the sideways movement in the disclosed embodiment refers to the movement of the material box along the second direction) before it can be transferred to the second transmission section 13.

The length direction of the first transmission section 12 and the second transmission section 13 extends along the first direction. The end of the first transmission section 12 away from the first introduction section 11 is used to connect with the second transmission section 13. The second transmission section 13 and the climbing section 14 are both located on the same side of the first transmission section 12, and along the first direction, the projections of the first transmission section 12 and the climbing section 14 relative to the plane are located on the same straight line.

Based on the above embodiment, the first selection position 16 is formed on the first transmission section 12, and the transmission mechanism 102 has a plurality of transmission rollers on the first transmission section 12, and 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 material box to move on the first transmission section 12.

Furthermore, in order to facilitate the sorting personnel to select the material box, the multiple transmission rollers on the first transmission section 12 are arranged at an angle. Along the second direction, the height of one end of the transmission roller facing the sowing wall is lower than that of the other end, so that when the material box moves on the first transmission section 12, the box opening of the material box can be tilted outward, which can facilitate the sorting personnel to sort the goods in the material box and improve the sorting efficiency.

In the disclosed embodiment, the transmission mechanism 102 also 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 transmission section 12 close to the second transmission section 13, that is, the first transfer mechanism is arranged at the right angle structure formed between the first transmission section 12 and the second transmission section 13.

The first transfer mechanism is used to transfer the material box from the first transmission section 12 to the second transmission section 13. For example, the first transfer mechanism can be a lifting transfer mechanism. When the material box moves to the position of the lifting transfer mechanism, the lifting transfer mechanism is activated and provides a lateral force to the material box. The direction of the lateral force is from the first side of the support frame to the second side, so that the material box can be moved from the first transmission section 12 to the second transmission section 13 under the action of the lifting force.

After the material box is sorted at the first picking position 16, it is transferred to the second transmission section 13 after passing through the first transfer mechanism. The transmission mechanism 102 is provided with multiple transmission rollers at intervals on the second transmission section 13, and the transmission rollers have a power source that can drive the material box to move in the second transmission section 13, so that the material box can move to the climbing section 14 and move out of the first sorting line 10 through the first export section 15.

The first export section 15 and the second transmission section 13 are located at different heights, and the two lift the material box from the second transmission section 13 to the first export 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 equipped with a power source, which can drive the material box to climb the slope, so as to lift the material box from the height of the second transmission section 13 to the height of the first export section 15.

A connecting section is provided between the first outlet section 15 and the climbing section 14, and the connecting section can be regarded as a horizontal extension section of the climbing section 14. Since a right-angle structure is formed between the climbing section 14 and the first outlet section 15, the material box needs to be moved laterally here by the second transfer mechanism.

The second transfer mechanism is arranged at one end of the first export section 15 close to the climbing section 14, and the second transfer mechanism is used to change the moving direction of the material box, so that the material box can be moved from the climbing section 14 to the first export section 15.

Furthermore, the second transfer mechanism can be a right-angle transfer mechanism, which includes a plurality of rollers for turning, wherein the rollers arranged near the climbing section rotate in the same direction as the moving direction of the material box on the climbing section 14; the rollers arranged near the first export section 15 rotate in the same direction as the moving direction of the material box on the first export section 15. When the material box moves to the second transfer mechanism, the material box can move from the climbing section 14 to the first export section 15 under the action of the second transfer mechanism, thereby moving out of the first sorting line 10.

Referring to Figures 2 and 4, in the disclosed embodiment, along the direction from the second sorting entrance to the second sorting exit, the second sorting line 20 includes a second introduction section 21, a third transmission section 22, a downhill section 23, a fourth transmission section 24 and a second export section 25 arranged in sequence; wherein, the second introduction section 21 is located above the first introduction section 11, one end of the second introduction section 21 is connected to one end of the third transmission section 22, and a right angle structure is formed between the two. The other end of the second introduction section 21 forms a second sorting entrance, and the second introduction section 21 is arranged in coordination with the second discharge port of the discharger 400, and the second discharge port and the second sorting entrance are at the same height, so that the material box to be sorted enters the second introduction section 21 from the second sorting entrance, that is, the second introduction section 21 is used to lead the material box to the second sorting line 20.

The second export section 25 is located below the first export section 15. One end of the second export section 25 is connected to one end of the fourth transmission section 24, and the two form a right-angle structure. The other end of the second export section 25 forms a second sorting outlet, and the second export section 25 is arranged in coordination with the second loading port of the feeder 500. The second loading port and the second sorting outlet are located at the same height, so that the material box to be sorted can be transferred from the second export section 25 and the second sorting outlet to the feeder 500, that is, the second export section 25 is used to lead the material box out of the second sorting line 20.

The third transmission section 22, the downhill section 23 and the fourth transmission section 24 are arranged between the second introduction section 21 and the second export 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 both located on the same side of the third transmission section 22, and along the first direction, the projections of the fourth transmission section 24 and the downhill section 23 relative to the plane are located on the same straight line.

Furthermore, the third transmission section 22 and the first transmission section 12 are located at different heights. For example, the third transmission section 22 is located above the first transmission section 12. The end of the third transmission section 22 away from the second introduction section 21 is used to connect with the downhill section 23. The downhill section 23 is connected with the fourth transmission section 24. In this way, the height of the fourth transmission section 24 can be reduced.

On the basis of the above embodiment, the transmission mechanism 102 is provided with a plurality of transmission rollers on the third transmission section 22, and the plurality of transmission rollers are arranged horizontally and spaced along the first direction, and the transmission rollers have a power source, which can drive the material box to move on the third transmission section 22. A right-angle structure is formed between the third transmission section 22 and the downhill section 23, and when the material box moves to the end of the third transmission section 22, it needs to move sideways so that the material box is transferred from the third transmission section 22 to the downhill section 23.

For example, a right-angle transfer mechanism is provided between the third transmission section 22 and the downhill section 23. When the material box moves to the right-angle transfer mechanism at the end of the third transmission section 22, the right-angle transfer mechanism can change the moving direction of the material box so that the material box moves from the third transmission section 22 to the downhill section 23.

The transmission mechanism 102 is provided with multiple transmission rollers in the downhill section 23. The transmission rollers may be transmission rollers without power source. The multiple transmission rollers are arranged at intervals to form a guide slope. Under the action of gravity, the material box can move from the downhill section 23 to the fourth transmission section 24. It is understandable that the transmission mechanism 102 may also be provided with a second transmission belt in the downhill section 23, and this embodiment is not limited to this.

The second selection position 26 is formed on the fourth transmission section 24. The transmission mechanism 102 is arranged with multiple transmission rollers on the fourth transmission section 24. The multiple transmission rollers are arranged horizontally and spaced along the first direction. The transmission rollers have a power source and can drive the material box to move on the first transmission section 12.

Since a right-angle structure is formed between the fourth transmission section 24 and the second export section 25, the material box needs to move sideways when it moves to the end of the fourth transmission section 24. In the disclosed embodiment, a right-angle transfer mechanism is provided between the fourth transmission section 24 and the second export section 25, and the right-angle transfer mechanism is used to change the moving direction of the material box so that the material box moves from the fourth transmission section 24 to the second export section 25, thereby moving the material box out of the second sorting line 20.

It should be noted that in the sorting platform 100 in the disclosed embodiment, the first introduction section 11, the first transmission section 12, the second transmission section 13, the fourth transmission section 24 and the second export section 25 can be located at the same height; the second introduction section 21, the third transmission section 22 and the first export section 15 can be located at the same height.

Such a setting can make the first sorting position 16 of the first sorting line 10 and the second sorting position 26 of the second sorting line 20 at the same height, so that the sorting personnel can sort the goods, and the first sorting entrance and the second sorting exit are at the same height, and the second sorting entrance and the first sorting exit are at the same height, so that the unloader 400 can transfer the material box to the sorting platform 100 and transfer the sorted material box to the loader 500, thereby improving the picking efficiency.

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

For example, the third transfer mechanism can be a lifting transfer mechanism, and the third transfer mechanism can be set up with reference to the first transfer mechanism, which will not be described here. When the material box moves to the third transfer mechanism located at the second transmission section 13, the third lifting transfer mechanism moves and provides lateral force to the material box, so that the material box moves from the second transmission section 13 to the fourth transmission section 24, thereby realizing the transfer of the material box from the first sorting line 10 to the second sorting line 20.

If the sorting path of the material box needs to pass through the first picking position 16 and the second picking position 26, the material box enters the first introduction section 11 and the first transmission section 12 from the first sorting entrance, and enters the second transmission section 13 through the first transfer mechanism after being sorted by the first picking position 16. When the material box passes through the third transfer mechanism, the third transfer mechanism transfers the material box to the fourth transmission section 24 of the second sorting line 20. After the material box is sorted by the second picking position 26, it can be moved out of the second sorting line 20.

Further, referring to FIG. 1 and FIG. 4 , the fourth transmission section 24 of the disclosed embodiment is also provided with an abnormal material box outlet 27, and the fourth transmission section 24 is also provided with a fourth transfer mechanism, which is provided at the abnormal material box outlet 27, and the fourth transfer mechanism is configured to be able to transfer the abnormal material box from the fourth transmission section 24 to the abnormal material box outlet 27, and then move out of the first sorting line 10 and/or the second sorting line 20.

For example, the abnormal material box outlet 27 can be set on the fourth transmission section 24 and avoid the second selection position 26. The fourth transfer mechanism can be a top-up transfer mechanism. When the abnormal material box moves to the top-up transfer mechanism, the top-up transfer mechanism moves and provides lateral force to the abnormal material box. Under the action of this lateral force, the abnormal material box moves to the abnormal material box outlet 27.

Preferably, the abnormal material box outlet 27 can be set at the end of the fourth transmission section 24 and opposite to the second export section 25. In this way, a transfer mechanism can be set at the end of the fourth transmission section 24 to control the normal material box to move from the fourth transmission section 24 to the second export section 25, or control the abnormal material box to move from the fourth transmission section to the abnormal material box outlet 27. This setting can save the manufacturing cost of the sorting platform and optimize its layout.

It should be noted that the abnormal material box may be from the first sorting line 10. If the barcode reader installed on the first sorting line 10 fails to recognize the label of the material box, it is determined whether the material box is an abnormal material box. If the material box is determined to be an abnormal material box, when the abnormal material box passes through the third transfer mechanism, the third transfer mechanism can transfer the material box from the second transmission section 13 of the first sorting line 10 to the fourth transmission section 24 of the second sorting line 20; further, when the material box passes through the fourth transfer mechanism, the fourth transfer mechanism transfers the material box to the abnormal material box outlet 27, thereby moving the abnormal material box out of the sorting platform 100.

With this arrangement, the abnormal material box can be moved out of the sorting platform 100 from the abnormal material box outlet 27, which can avoid congestion when the material box moves on the sorting platform, further improve the flow of the material box on the sorting platform 100, and improve the sorting efficiency.

It should be noted that among the first transfer mechanism, the second transfer mechanism, the third transfer mechanism and the fourth transfer mechanism in this embodiment, the first transfer mechanism, the third transfer mechanism and the fourth transfer mechanism are lifting transfer mechanisms, and the second transfer mechanism is a right-angle transfer mechanism. This is only an example of the specific implementation scheme of this embodiment and does not represent a limitation thereto. For example, according to the turning requirements of the material box on the first sorting line 10 and the second sorting line 20 and the layout space at the turning point, a lifting transfer mechanism or a right-angle transfer mechanism can be selectively set at each turning point.

Implementation Example 2

As shown in FIG5 , the disclosed embodiment provides a picking method, which is implemented based on the sorting system in the first embodiment and includes the following steps:

Step S100: Determine the picking position corresponding to the sorting box.

Specifically, the sorting system obtains the order information of the goods to be sorted, and transmits the order information to the server of the sorting system. The server sends the order to the sorting position according to the order information, and then determines the sorting position corresponding to the material box to be sorted corresponding to the order. For example, the picking position of the material box to be sorted is the first picking position 16 and/or the second picking position 26.

Step S200: Determine the target discharge port corresponding to the material box to be sorted according to the sorting position.

Specifically, the server of the sorting system determines the sorting position of the to-be-sorted material box according to the cargo order information, and determines the target discharge port corresponding to the sorting position; the target discharge port includes a first discharge port and a second discharge port, the first discharge port can be connected to the first sorting entrance of the first sorting line 10, and the to-be-sorted material box is transferred to the first sorting position 16 and/or the second sorting position 26, and the second discharge port can be connected to the second sorting entrance of the second sorting line 20, and the to-be-sorted material box is transferred to the second sorting position 26.

It should be noted that when the target discharge port of the material box to be sorted is determined, the target loading port of the corresponding sorted material box is also determined accordingly. For example, if the target discharge port is the first discharge port, the corresponding target discharge port is the first loading port.

For example, in one embodiment, when the sorting position is the first sorting position 16, the target discharge port of the material box to be sorted is determined to be the first discharge port, and the target loading port corresponding to the material box after sorting is the first loading port of the loading machine 500, and the first discharge 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 to the first discharge port, and the first sorting outlet is connected to the first loading port.

For example, when the picking position is the first picking position 16, the moving route determined by the material box on the first sorting line 10 is: entering the first sorting line 10 through the first sorting entrance, and passing through the first introduction section 11, the first transmission section 12, the second transmission section 13, the climbing section 14 and the first export section 15 in sequence, and moving out of the first sorting line 10 through the first sorting outlet, so that the material box completes the sorting of the first picking position 16.

In another embodiment, when the picking position is the second picking position 26, the target discharge port of the material box to be sorted is determined to be the second discharge port; the target loading port corresponding to the material box after sorting is the second loading port of the loading machine 500, and the second discharge port and the second loading port correspond to the second sorting line 20 respectively, the second sorting entrance of the second sorting line 20 is connected to the second discharge port, and the second sorting exit is connected to the second loading port.

For example, when the picking position is the second picking position 26, the moving route determined by the material box on the second sorting line 20 is: entering the second sorting line 20 through the second sorting entrance, and passing through the second introduction section 21, the third transmission section 22, the downhill section 23, the fourth transmission section 24 and the first export section 15 in sequence, and moving out of the second sorting line 20 through the second sorting outlet, so that the material box completes the sorting of the second picking position 26.

In another embodiment, when the picking positions are the first picking position 16 and the second picking position 26, the target discharge port of the material box to be sorted is determined to be the first discharge port; the target loading port corresponding to the material box after sorting is the second loading port, wherein the first discharge port is connected to the first sorting inlet of the first sorting line 10, and the second loading port is connected to the second sorting outlet of the second sorting line 20.

For example, when the picking positions are the first picking position 16 and the second picking position 26, the moving route of the material box is: entering the first sorting line 10 through the first sorting entrance, and passing through the first introduction section 11, the first transmission section 12, the second transmission section 13 in sequence, and entering the second sorting line 20 from the second transmission section 13 through the third transfer mechanism.

The moving route on the second sorting line 20 is: passing through the fourth transmission section 24 and the second export section 25 in sequence, and moving out of the second sorting line 20 through the second sorting outlet, so that the material box completes the sorting of the first picking position 16 and the second picking position 26; that is, when the picking positions are the first picking position 16 and the second picking position 26, the running route of the material box to be sorted is to pass through the first introduction section 11, the first transmission section 12, the second transmission section 13, the third transfer mechanism, the fourth transmission section 24 and the second export section 25 in sequence.

Step S300: Control the unloader 400 to transfer the material box to be sorted through the target unloading port to the sorting entrance corresponding to the target unloading port.

Specifically, the unloader 400 is configured to align its target unloading port with the corresponding sorting port according to the instruction, so that the material box is transmitted to the corresponding sorting port through the target unloading port, so that the material box moves to the corresponding sorting position according to the set operation route.

On the basis of the above-mentioned embodiments, the picking method provided by the disclosed embodiments further includes: after the material box to be sorted is sorted at the first picking position 16, judging whether the material box to be sorted is the material box corresponding to the second picking position 26 according to the reading result of the code reader on the second transmission section 13, and controlling the material box to continue moving along the first sorting line 10 or transferring the material box to the second picking position 26 of the second sorting line 20 for picking according to the judgment result. With this arrangement, compared with the need for the material box to enter two different sorting positions from two sorting ports respectively, the disclosed embodiment allows the material box to enter the sorting port only once, and can realize the sorting of the material box at the first sorting position 16 and the second sorting position 26, thereby improving the sorting efficiency of the material box.

Specifically, after the material box to be sorted is sorted at the first picking position 16, it can enter the second transmission section 13 through the first transfer mechanism. The second transmission section 13 is provided with a code reader, which can be used to identify the label of the material box. According to the reading result of the code reader, it is determined whether the material box needs to be sorted through the second picking position 26.

When the material box needs to be sorted through the second picking position 26, when the material box moves to the third transfer mechanism, the third transfer mechanism moves to transfer the material box from the second transmission section 13 to the fourth transmission section 24. The material box continues to move in the fourth transmission section 24, and after being sorted through the second picking position 26, it moves out of the sorting platform 100 from the second sorting outlet and returns to the warehouse through the loader 500.

When the material box does not need to pass through the second picking position 26 for picking, the material box needs to continue to move along the first sorting line 10, that is, the material box needs to pass through the second transmission section 13, the climbing section 14 and the first export section 15 in sequence, and move out of the sorting platform 100 from the first sorting outlet and return to the warehouse through the loader 500.

The sorting method provided by the disclosed embodiment also includes using a barcode reader to identify the label of the material box. If the barcode reader cannot identify the label of the material box, the material box is determined to be an abnormal material box, and the material box is controlled to be transported to the abnormal material box outlet 27. In this way, the abnormal material box can be moved out of the sorting platform 100 from the abnormal material box outlet 27, which can avoid congestion when the material box moves on the sorting platform, further improve the flow of the material box on the sorting platform 100, and improve the sorting efficiency.

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. The abnormal material box outlet 27 is arranged on the fourth transmission section 24 of the second sorting line 20. For the material box located on the second sorting line 20, the code reader arranged between the second sorting entrance and the abnormal material box outlet 27 can be used to identify the label of the material box and judge whether the material box is an abnormal material box. If so, when the abnormal material box moves to the fourth transfer mechanism of the fourth transmission section 24, the fourth transfer mechanism is actuated and can transport the abnormal material box to the abnormal material box outlet 27.

Furthermore, for the material box located on the first sorting line 10, the label of the material box can be identified by using the barcode reader arranged between the first sorting entrance and the third transfer mechanism. For example, the label of the material box can be identified by using the barcode reader arranged on the first transmission section, and it can be determined whether the material box is an abnormal material box. If the material box is an abnormal material box, when the abnormal material box moves to the third transfer mechanism, the third transfer mechanism can move the abnormal material box from the second transmission section to the fourth transmission section, and the abnormal material box continues to move in the fourth transmission section. When the abnormal material box moves to the fourth transfer mechanism of the fourth transmission section 24, the fourth transfer mechanism moves and can transport the abnormal material box to the abnormal material box outlet 27.
