A method for picking and distributing goods in and out of a three-dimensional warehouse

Abstract

The invention relates to the technical field of stereoscopic warehouses, and provides a method for goods in-and-out warehousing and goods distribution based on stereoscopic warehouses. The method determines characteristic information of goods to be in-warehouse based on the type of goods, determines the position information of the goods to be in-warehouse, and divides the types of goods by the daily shipment quantity and the appearance and packaging information of the goods. The method matches the characteristic information of the goods to be in-warehouse with images of goods allowed to be in-warehouse, and can quickly and accurately locate the warehouse location corresponding to the warehousing operation, and instruct a robot to accurately sort and put the goods on the shelves. For the goods out of the warehouse location, the method generates goods out-of-warehouse attribute information by acquiring store order information. The method generates information of goods allowed to be out-of-warehouse, and uses a robot to transport the goods allowed to be out-of-warehouse to a warehouse out transit area, so as to realize the out-of-warehouse operation of the warehouse location. The entire in-and-out process uses the robot to automatically identify and transport the goods, thereby reducing the labor cost of the entire goods in-and-out process and improving the efficiency and accuracy of the goods in-and-out.

Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to a method for allocating goods for inbound and outbound distribution based on a stereoscopic warehouse. Background Art

[0002] At present, the only smart hardware used in store warehouses are electronic label shelves and turnover box conveyor roller conveyor lines, which are mainly semi-automated sorting equipment and heavily rely on manual labor, resulting in low efficiency in warehousing and outbound delivery of goods. Moreover, most of the current warehousing and outbound sorting operations are manually participated in, and each operation process requires the participation of multiple personnel. The overall error rate is about 1%-2%, which increases operating costs.

[0003] Therefore, it is necessary to propose further solutions to solve the problem that the warehousing and warehousing of goods are heavily dependent on manual labor and have low work efficiency. Summary of the invention

[0006] The warehousing method includes the following steps:

[0007] Step S1001, scanning the barcode of the goods to be stored, determining the characteristic information of the goods to be stored, the characteristic information of the goods to be stored includes the daily shipment quantity of the goods, the appearance and packaging information of the goods, and the type of the goods; based on the daily shipment quantity of the goods, if the daily shipment quantity of the goods is greater than or equal to a preset value, determining that the storage method of the corresponding type of goods is to stack multiple whole goods on a pallet and store the entire pallet on a shelf; if the daily shipment quantity of the goods is less than the preset value, determining that the corresponding type of goods needs to be stored on a shelf separately;

[0008] Step S1002: Based on the characteristic information of the goods to be stored, a storage instruction is generated and sent to the corresponding depalletizer, and the depalletizer obtains the position information of the goods to be stored that currently needs to be transported;

[0009] Step S1003: Based on the warehousing instruction, instruct the depalletizer to extract the goods to be stored according to the position information of the goods to be stored, and screen and locate the characteristic information of the goods to be stored, including instructing the depalletizer to shoot the goods to be stored to obtain images of goods allowed to be stored; matching the characteristic information of the goods to be stored and the images of the goods allowed to be stored, determining the storage location corresponding to the warehousing operation, and transporting the screened and located goods allowed to be stored to the corresponding location for storage;

[0010] Step S1004: The stacker puts the goods that are allowed to enter the warehouse and are screened and located in step S1003 on the shelves;

[0011] The outbound method includes the following steps:

[0012] Step S2001: Goods are shipped out, store order information is obtained, the goods shipping attribute information of the corresponding type of goods that need to be shipped out is obtained, and the goods shipping instruction is output; the goods name information, goods model information, and goods demand information of the corresponding type of goods that need to be shipped out are obtained, and this is used as the goods attribute information for replenishment operations on the store side;

[0013] Step S2002: Cargo verification: Based on the cargo outbound instruction, the robot is instructed to transport the cargo to the verification station along the outbound conveyor line; the cargo is scanned and tested to generate cargo information that is allowed to be outbound;

[0014] Step S2003: Cargo cache, obtain the vacancy signal of the outbound transit area, generate vacancy attribute information, match the vacancy attribute information with the information of the cargo that is allowed to be outbound, and obtain the position information of the cargo that is allowed to be outbound that the robot currently needs to transport; and transport the screened and located cargo that is allowed to be outbound to the corresponding position of the outbound transit area for storage; obtain the store information and the cargo name information and quantity of the corresponding type of cargo that the store needs to take for replenishment, and use this as the vacancy attribute information.

[0015] In an embodiment disclosed in the present application, step S1003 also includes the following steps: after the depalletizer transports the goods to the corresponding location, it returns along the way and continues to perform the next commodity warehousing task.

[0016] In one embodiment disclosed in the present application, based on the type of the goods, if the goods to be stored are fragile and easily damaged, it is determined that the storage method for the corresponding type of goods is to disassemble them into individual pieces and store them on shelves.

[0017] In one embodiment disclosed in the present application, based on the cargo packaging information, if the cargo packaging to be stored has a special design, it is determined that the storage method for the corresponding type of cargo is to manually disassemble and sort the cargo into warehouse.

[0018] The beneficial technical effects achieved by the present invention are:

[0019] The present invention has a high degree of automation. By establishing multiple storage locations in the stereoscopic warehouse, each storage location cooperates with the stacker and depalletizer RGV robots to realize different shelving storage methods for different goods in the warehousing operation link, and can automatically identify the type of goods, thereby reducing the number of people in the sorting link, improving the sorting accuracy and work efficiency when the goods are warehousing, and making the stereoscopic warehouse operation more efficient and low-cost.
