Embodiment 1

[0034] An embodiment of the present invention provides a method for order picking, which is applied to orders including various required goods, and the required goods are stored on the storage positions of the warehouse, and the vertical lanes and the horizontal lanes form nodes.

[0035] Such as Figure 4 As shown, the method includes:

[0036] Step 401, according to the placement of warehouse shelves, generate a warehouse floor plan; calculate and store the information of roadways and nodes; calculate and store the shortest path between each node in the warehouse; store the location information of the goods, the size of the goods and weight information.

[0037] Step 402, when picking an order, search for the location, size and weight of the goods required in the order from the pre-stored data; demand; and calculate the shortest path between any two required goods by using the shortest path between the nodes stored in advance;

[0038] Step 403, according to the capacity ...

Embodiment 2

[0043] An embodiment of the present invention provides a method for order picking, which is applied to orders including various required goods. The above method will be described in detail below on the basis of Embodiment 1, and the same content as Embodiment 1 will not be repeated.

[0044] Such as Figure 5 As shown, the above method of order picking includes:

[0045] Step 501, according to the placement of the warehouse shelves, generate a floor plan of the warehouse; calculate the information of the lanes and nodes; calculate the shortest path between the nodes in the warehouse.

[0046] In one embodiment, the access location of the required goods is in the roadway, and the longitudinal roadway and the transverse roadway form a node. For example, if Image 6 As shown, the roadway is the passage for the picking workers to access the goods, and it is assumed that there are only two straight roadways, longitudinal and horizontal. Nodes are the intersections of longitudina...

Embodiment 3

[0129] An embodiment of the present invention provides an order picking system, which is applied to order picking that needs to move horizontally in multiple lanes, such as Figure 12 As shown, the system includes: a server, a wireless local area network, and a mobile terminal; wherein,

[0130] Such as Figure 13 As shown, the server includes: a drawing unit 1301, a storage unit 1302, a computing unit 1303, and a solving unit 1304; wherein,

[0131] The drawing unit 1301 is used to generate the floor plan of the warehouse according to the placement of the warehouse shelves; calculate the information of the lanes and nodes; calculate the shortest path between the nodes in the warehouse;

[0132] The storage unit 1302 is used to store information on the location, size and weight of the goods, as well as the information on the lanes and nodes; store the shortest path between each node in the warehouse;

[0133] Calculation unit 1303 is used to search the location, size and wei...

Abstract

The embodiment of the invention provides order sorting method and system. The method comprises the steps of: generating a storehouse plane layout according to the putting condition of storehouse shelves; then computing the shortest path between nodes in a storehouse; finding out the positions, sizes and the weight of goods required for an order from pre-stored data; computing the shortest path and distance between any two pieces of required goods by using the shortest path between the nodes; and computing the optimal sorting path according to the capacity of sorting equipment and the required quantity of the required goods in the order so as to sort orders by the sorting equipment according to the optimal sorting path. The embodiment of the invention can effectively compute the sorting path, reduce the working cost, enhance the working efficiency, and solve the problems of inconsistent shelf arrangement, relatively small shelf height, and small expense difference caused by storing and taking the goods on different layers of shelves of the same goods position; and sorting workers mainly need to optimize order sorting problem in the horizontal movement distance for sorting work.

Description

technical field [0001] The invention relates to the field of warehouse picking operations in logistics warehousing, in particular to an order picking method and system that needs to move horizontally in multiple lanes. Background technique [0002] Warehouse picking operation is the core of modern logistics distribution, and the level of modernization of logistics distribution depends on the picking technology. Many large warehouses or distribution centers use high-rise shelf-type three-dimensional warehouses. There is an aisle between two adjacent rows of shelves, and each aisle has a stacker. The stacker can move along the vertical and horizontal directions at the same time. Goods on side vertical shelves. Such as figure 1 As shown, point 0 is the entrance and exit of the roadway, and a, b, c, d, e, f are several pick-up points on the vertical shelf. The stacker can pick up the goods on several positions at a time, and then return to point 0 Place the case on the convey...
