[0047] In the above description, inventory goods are in storage state, not matched order goods, inventory goods are generally stored by category, the same kind of goods is gathered and placed in the goods compartment of storage rack 1.The above order goods refers to the goods gathered according to order, when executing sorting operation, each compartment of distribution wall 2 will be bound with order, after binding, the goods corresponding to order are detected and gathered in the corresponding compartment, all goods in the same compartment are the goods in the same order, the goods in the compartment are called order goods.

[0048] For convenience of description, the storage rack 1 for storing inventory goods and the storage rack 1 constituting the distribution wall 2 are respectively called storage rack with storage function and storage rack with distribution function, the storage rack with storage function is represented by 1a in the drawing, the storage rack with distribution function is represented by 1b in the drawing, both of which adopt the same specification of storage rack 1, in this way, there is no need to specially customize distribution wall 2, the storage rack with storage function 1 and the storage rack with distribution function 1 can be converted to each other, which saves cost and is convenient for management.In addition, the storage rack with storage function 1 and the storage rack with distribution function 1 can be moved by the carrying device 4 with the same structure, which also facilitates the unified scheduling of carrying device 4 and does not need to be classified and scheduled.

[0049] In actual operation, all storage racks 1 have unique ID numbers, and the control system can define the attributes of a part of the ID numbers of the storage racks 1 as distribution purpose, that is, for storing order goods;The attributes of another part of the ID numbers of the storage racks 1 are defined as storage purpose, that is, for storing inventory goods.With the operation of the system, the control system can redefine the attributes of the ID numbers of the storage racks 1 as needed to complete the function conversion of the storage racks 1 with two functions.

[0050] The carrying device 4 can be existing carrying device such as jacking type handling robot, traction type AGV, forklift, etc., or new form of carrying equipment that will appear in the future.

[0051] Preferably, multiple sides of the storage rack 1 have storage positions, and the carrying device 4 can rotate the storage rack 1 so that different sides of the storage rack 1 become the working surface.

[0052] Preferably, a fixed label rack 5 is also arranged at the working station 3, as shown in Figure 3 The label rack 5 includes a frame 51 and multiple labels 52 arranged in an array on the frame 51, as shown in Figure 4 When the storage rack 1 constituting the pick wall 2 is docked to the working station 3, the position of each storage position (i.e. the compartment of the pick wall 2) of the storage rack 1 has a corresponding label 52. Preferably, when the pick task is performed manually at the working station 3, a prompt unit such as a prompt light is arranged at the position corresponding to each label 52. Taking the prompt light as an example, when the staff at the working station 3 checks out the goods corresponding to an order, the staff scans the goods, and the control system learns the compartment corresponding to the order of the scanned goods, and controls the prompt light at the corresponding compartment to light up, so that the staff can quickly find the target compartment and put the goods into it. When the pick task is performed by a mechanical hand or other picking equipment at the working station 3, the label 52 can be a two-dimensional code, an electronic tag or other machine-recognizable label, and the picking equipment has a recognition unit for recognizing the label 52. After the picking equipment checks out the goods from the storage rack 1 storing the goods, the control system can identify the label 52 of the compartment through the recognition unit before the picking equipment puts the goods into the corresponding compartment, so as to determine the compartment and prevent the goods from being put into the wrong compartment.

[0053] Preferably, a pick wall buffer area B and a packaging area C are further included; and the carrying device 4 can transfer the storage rack 1 for storing order goods between any two of the working station 3, the pick wall buffer area B and the packaging area C.

[0054] The application also provides a pick method based on the mobile pick wall, as shown in Figure 5 The method is based on the pick system described above, and includes the following steps S601-S606:

[0055] Step S601: scheduling the carrying device 4 to move the storage rack 1 for picking to the working station 3 to form the pick wall 2;

[0056] Step S602: allocating an order to an idle compartment of the pick wall 2;

[0057] Step S603, the carrying device 4 is scheduled to move the storage rack 1 with storage function from the storage area A to the workstation 3 for docking; the carrying device 4 performs the transfer operation on the storage rack 1 after docking with the storage rack 1, and then performs other carrying tasks after the carrying device 4 transports the storage rack 1 to the position and disengages from the storage rack 1.

[0058] Step S604, updating the order status corresponding to each slot of the distribution wall 2 according to the data generated by the distribution operation;

[0059] Step S605, judging whether the storage rack 1 for distribution meets the release condition, and if yes, releasing the storage rack 1;

[0060] Step S606, scheduling the carrying device 4 to transfer the released storage rack 1 out of the workstation 3.

[0061] In the above process, the carrying device 4 is scheduled to move the storage rack 1 with storage function and the storage rack 1 with distribution function to the workstation 3 for docking and leave the workstation 3, and the number of orders that can be processed by the workstation 3 at the same time is obviously increased. When multiple workstations 3 perform distribution operations at the same time, due to the increase in the number of orders processed at the same time, the storage rack 1 of the same storage function can match more orders in the same storage area A after leaving the storage area A, and more workstations 3 can complete the matching of goods. In this way, the order sorting efficiency can be obviously improved. Since the distribution wall 2 has the attribute of being detachable and movable, it is not necessary to obtain order goods from the distribution wall 2 by manually or by scheduling a bin robot or other equipment, and the carrying device moving the storage rack 1 with storage function in the traditional sorting system can detach and transfer the distribution wall 2. The order goods corresponding to the same storage rack 1 can be transferred at one time, which can improve the transfer efficiency of order goods and save costs. Since the distribution wall 2 can be detached and moved, the difficulty of moving the distribution wall 2 is reduced, and the flexibility is increased. The storage rack 1 corresponding to the completed orders can be transferred and replaced in time.

[0062] Preferably, the plurality of sides of the storage rack 1 have storage positions, and the method further comprises steps S701-S702:

[0063] Step S701, judging whether the order status corresponding to the slots on the working surface in the storage rack 1 constituting the distribution wall 2 is all in the completed state, to obtain a first judgment result;

[0064] Step S702, when the first judgment result is yes, scheduling the carrying device 4 to change the surface of the distribution wall 2, so that the other side of the carrying device 4 serves as the working surface.

[0065] Preferably, a fixed label rack 5 is also provided at the workstation 3, the label rack 5 comprising a frame 51 and a plurality of labels 52 arranged in an array on the frame 51; after the dispatching the carrying device 4 to move the storage rack 1 to the workstation 3 to form the dispatch wall 2 in step S601, the method further comprises the following step S801:

[0066] In step S801, the information of each storage location of the storage rack 1 is bound to the information of the label 52. In this way, when performing the dispatching operation, the information of the storage location of the storage rack 1, the order information and the information of the label 52 can be bound together. When the storage rack 1 for dispatching receives the order goods at the workstation 3, the staff or sorting equipment of the workstation can perform the dispatching operation according to the information of the label 52, without the need to identify the storage location of the storage rack 1, which can improve the efficiency and avoid errors; after the storage rack 1 for dispatching leaves the workstation 3, the goods can be extracted according to the correspondence between the storage location information and the order information. It can be seen that the combination of the label 52 and the storage rack 1 forms the dispatch wall 2, which can facilitate data management at each link.

[0067] Preferably, the dispatch system further comprises a dispatch wall buffer area B and a packaging area C; after the storage rack 1 whose each grid opening corresponds to an order state of the dispatch wall 2 is all in a completed state, and the carrying device 4 is dispatched to transfer the storage rack 1 out of the workstation 3 in step S605, the method further comprises the following steps S901-S905:

[0068] In step S901, it is determined whether the dispatch wall buffer area B has the storage rack 1 to be packaged; a second determination result is obtained.

[0069] In step S902, when the second determination result is yes, the storage rack 1 is transferred to the dispatch wall buffer area B.

[0070] In step S903, when the second determination result is no, it is determined whether the packaging area C has an empty packaging station C1, and a third determination result is obtained.

[0071] In step S904, when the third determination result is yes, the storage rack 1 is transferred to the empty packaging station C1.

[0072] In step S905, when the third determination result is no, the storage rack 1 is transferred to the dispatch wall buffer area B.

[0073] In the above step, the packaging station C1 in the packaging area C gives priority to meeting the packaging demand of the storage shelves 1 in the dispatch wall buffer area B. When there is no storage shelf 1 to be packaged in the dispatch wall buffer area B and there is still an empty packaging station C1 in the packaging area C, the processed storage shelf 1 in the storage area A can be directly transferred to the packaging area C without transferring to the dispatch wall buffer area B, which can improve the efficiency and make the process reasonable.

[0074] Preferably, the step S605 of judging whether the storage shelf 1 for dispatching meets the release condition and releasing the storage shelf 1 if yes includes the following steps A1-A5.

[0075] Step A1, judging whether the storage shelf 1 has a grid with an unmatched order, to obtain a fourth judgment result;

[0076] Step A2, when the fourth judgment result is no, when the status of all orders matched by the storage shelf 1 is complete, the storage shelf 1 is released;

[0077] Step A3, when the fourth judgment result is yes, judging whether there is a remaining order in the order pool to obtain a fifth judgment result;

[0078] Step A4, when the fifth judgment result is yes, assigning an order to the grid with an unmatched order;

[0079] Step A5, when the fifth judgment result is no, when the status of all orders matched by the storage shelf 1 is complete, the storage shelf 1 is released.

[0080] Preferably, the step S605 of judging whether the storage shelf 1 for dispatching meets the release condition and releasing the storage shelf 1 if yes includes the following steps A1-A5.

[0081] Judging whether a manual release instruction is received, if yes, no longer assigning an order to the corresponding storage shelf 1 or waiting to assign an order, and when all assigned orders are in a complete state, releasing the storage shelf 1.

[0082] The above is only the preferred embodiment of the present application. It should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered within the scope of protection of the present application.
