Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management, and particularly relates to a method, device and equipment for realizing inbound storage in a buffer area based on an automated guided vehicle (AGV). Background Art

[0002] Currently, the warehousing inbound operation mainly adopts a manual operation method, which has a large workload, low work efficiency, repetitive and cumbersome work, and is prone to errors. Moreover, with the annual growth of the distribution network reserve and marketing reserve operations, the warehousing inbound operation cannot adapt to the increasing business scale; at the same time, the warehousing operation lacks information support means, and the statistical data mainly relies on manual operation. The inventory data and warehouse inbound and outbound documents cannot be accurately transmitted to the material management system, resulting in a large workload.

[0003] Specifically, the current warehousing inbound operation mainly has the following problems:

[0004] (1) The utilization rate of the high-level storage locations on the shelves is low. For example, the existing warehouse shelves are 6-story high racks. To place goods on the high-level storage locations, a reach truck needs to be manually driven, resulting in low efficiency for inbound storage on the shelves and outbound preparation, and there are significant operation risks.

[0005] (2) The degree of automation of the existing operation equipment in the warehouse is not high. The existing warehousing operation equipment in the warehouse mainly includes: shelves, diesel forklifts, electric forklifts, overhead cranes, pallets, storage cages, aerial work platforms, manual forklifts, etc. The material inbound and outbound mode remains in the traditional manual operation mode. The handling of palletized goods, bin goods, and yard goods relies on manual operation to design the handling mode, with low efficiency, large workload, and easy to make mistakes.

[0006] (3) Currently, the inbound and outbound of materials in the warehouse all rely on the material system module in the asset system. For the handling of warehousing operations, it is necessary to initiate data in the system and print paper documents → the warehouse keeper verifies the data on site → the material system confirms the completion of the data, etc. During the on-site operation process of warehousing management, business documents related to inventory such as inbound, outbound, transfer, and allocation are generated, and manual entry operations into the system are required. The system operation workload is large and prone to errors.

[0007] Therefore, there is an urgent need for a method that can automatically transport goods into the warehouse. Summary of the Invention

[0008] In view of this, the present invention provides a method, device and equipment for realizing inbound storage in a buffer area based on an automated guided vehicle (AGV) to solve the problem that traditional manual operation in warehousing inbound operations cannot achieve automatic handling of goods.

[0018] When there is a difference between the pallet list and the physical pallets, the review is unqualified, and the physical pallets or the pallet list are readjusted until there is no difference between the pallet list and the physical pallets.

[0019] The method for realizing buffer area warehousing based on an AGV provided by the present invention compares the pallet list with the physical pallets. When there is no difference between the pallet list and the physical pallets, the review is qualified. When there is a difference between the pallet list and the physical pallets, the review is unqualified, and the physical pallets are readjusted until there is no difference between the pallet list and the physical pallets, making the pallet list and the physical pallets correspond one by one, providing a non-differential data basis for the subsequent accurate warehousing of physical pallets.

[0020] In an alternative embodiment, after the physical pallet is wrapped with film, controlling the automated guided vehicle (AGV) to transport the physically pallet after film wrapping to the surplus material return port for scanning and storing it in the corresponding automated storage and retrieval system (AS / RS) includes:

[0021] Conduct an external inspection on the physically pallet after film wrapping at the surplus material return port to determine whether it is qualified.

[0022] When the external inspection is qualified, scan the physically pallet after the qualified external inspection, and control the AGV to transport the physically pallet to the corresponding AS / RS.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0052] According to an embodiment of the present invention, there is provided an embodiment of a method for realizing buffer area warehousing based on an automated guided vehicle (AGV). It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0053] In this embodiment, a method for realizing buffer area warehousing based on an AGV is provided, which can be used in a warehousing system. The warehousing system includes a stretch wrapping platform, a surplus material return port, and multiple automated storage and retrieval systems (AS / RS). Figure 1 is a flowchart of a method for realizing buffer area warehousing based on an AGV according to an embodiment of the present invention, as Figure 1 shown, the process includes the following steps:

[0054] Step S101, obtain a pallet list to be warehoused.

[0055] Specifically, taking the warehousing of finished wine as an example, the warehousing process of finished wine is as follows: The packaging production department initiates a warehousing application and transmits it to the packaging material procurement and supply control center for the warehousing of finished wine. After the finished wine is packaged, it is finally placed on pallets in the pallet buffer area in the form of whole cases. The warehousing of the packaged finished wine needs to meet the storage requirements of the AS / RS, including: the stack of finished wine turnover boxes (including the caps / handbags of finished wine, and the stack of turnover boxes needs to be stretch wrapped before warehousing), and the gift box stack needs to be capped (the gift boxes need to be stretch wrapped before warehousing). The packaged finished wine and the pallets together form pallet physical objects. It should be noted that each pallet is printed with a pallet barcode.

[0056] The pallet list to be warehoused can be sorted out by using the query system of the warehouse keeper in the packaging production department. Specifically, the query system of the warehouse keeper in the packaging production department is used to sort the pallet physical objects that need to be warehoused from the pallet buffer area into a pallet list to be warehoused according to the product name, product batch, and product warehousing quantity. The pallet list to be warehoused can be in electronic form or paper form. When the pallet physical objects need to be warehoused, the packaging production department initiates a pallet warehousing application and transmits the application and the pallet list to be warehoused to the packaging material procurement and supply control center. The packaging material procurement and supply control center includes an Extended Warehouse Management (EWM) system and a Warehouse Control System (WCS).

[0057] Step S102, review the pallet list to be warehoused based on preset review conditions.

[0058] Specifically, when the warehouse management system EWM of the packaging material procurement and supply control center receives a pallet inbound application initiated by the packaging production department, it audits the pallet list to be warehoused based on preset audit conditions. The preset audit conditions are set according to the actual situation. For example, the preset audit condition is whether the pallet list corresponds one-to-one with the physical pallets.

[0059] Step S103, when the audit is qualified, create a stock transfer task based on the qualified pallet list and send the stock transfer task to the automated guided vehicle; the stock transfer task includes moving the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform.

[0060] Specifically, when the audit is qualified, the warehouse management system EWM creates a stock transfer task based on the qualified pallet list and sends the stock transfer task to the warehouse control system WCS. The warehouse control system WCS controls the movement of the automated guided vehicle AGV (Automated Guided Vehicles, automated guided vehicle, abbreviated as AGV); the stock transfer task includes moving the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform. When creating the stock transfer task, the warehouse management system EWM needs to create the stock transfer task based on the product name, product batch, product inbound quantity listed on the pallet list, and the preset pallet owner comparison table in the warehouse management system EWM. The preset pallet owner comparison table includes warehouse numbers, bin numbers, and owner information corresponding to the pallet barcode, product name, product batch, and product inventory quantity, etc.

[0061] Step S104, control the automated guided vehicle to execute the stock transfer task, so that the automated guided vehicle moves the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform for pallet stretch wrapping.

[0062] Specifically, stretch wrapping, also known as stretch film, also called packaging film or shrink film, is a film material made of polyethylene (PE). It has high strength, flexibility, and ductility and is widely used for the packaging and protection of goods. The stretch film is tightly wrapped around the product / goods through the mechanical equipment on the stretch wrapping platform to protect the product from damage.

[0063] The warehouse control system WCS controls the automated guided vehicle to execute the stock transfer task under the control instruction of the packaging material procurement and supply control center, so that the automated guided vehicle moves the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform for pallet stretch wrapping.

[0064] Step S105, when the physical pallet stretch wrapping is completed, control the automated guided vehicle to move the physically pallet after stretch wrapping to the surplus material return port for scanning and then send it to the corresponding automated warehouse.

[0065] Specifically, after the physical pallet is wrapped with film, the Warehouse Control System (WCS) controls the Automated Guided Vehicle (AGV) to transport the physically wrapped pallet to the surplus material return port for scanning under the control instruction of the packaging material procurement and supply control center. The scanning is achieved by using a PDA (Personal Digital Assistant) barcode scanner to scan the pallet barcode. After the scanning is completed, the physical pallet is sent to the corresponding automated warehouse according to the product name, product batch number, product inbound quantity on the physical pallet, and the corresponding warehouse number, storage location number, and consignor information in the preset pallet consignor comparison table.

[0066] The method for realizing the inbound of the buffer area based on the Automated Guided Vehicle provided in this embodiment obtains the list of pallets to be inbound, and based on the one-to-one correspondence between the pallet list and the physical pallet, uses the Automated Guided Vehicle to automatically transport the physical pallets in the pallet buffer area to the film wrapping platform for pallet film wrapping, and scans and sends them to the corresponding automated warehouse, achieving the purpose of automatically transporting goods, improving the efficiency of the physical pallet inbound, improving the warehouse operation efficiency and reducing the labor cost, providing a basis for the efficient management of the warehousing system, and solving the problem that the traditional manual operation in the warehousing inbound business cannot realize the automatic transportation of goods.

[0067] In this embodiment, a method for realizing the inbound of the buffer area based on the Automated Guided Vehicle is provided, which can be used in a warehousing system. The warehousing system includes a film wrapping platform, a surplus material return port, and multiple automated warehouses. Figure 2 is a flowchart of the method for realizing the inbound of the buffer area based on the Automated Guided Vehicle according to the embodiment of the present invention, as Figure 2 shown, this process includes the following steps:

[0068] Step S201, obtain the list of pallets to be inbound. For details, please refer to Figure 1 step S101 of the shown embodiment, which will not be elaborated here.

[0069] Step S202, review the list of pallets to be inbound based on the preset review conditions.

[0070] Specifically, the preset review conditions include that there is no difference between the pallet list and the physical pallet. The above step S202 includes:

[0071] Step S2021, compare the pallet list with the physical pallet. When there is no difference between the pallet list and the physical pallet, the review is qualified.

[0072] Specifically, compare the product name, product batch number, and product inbound quantity listed on the pallet list with the physical product name, product batch number, and product inbound quantity on the physical pallet. When there is no difference, the review is qualified.

[0073] In step S2022, if there are differences between the pallet list and the physical pallets, the audit fails. The physical pallets or the pallet list shall be readjusted until there are no differences between the pallet list and the physical pallets.

[0074] Specifically, compare the product names, product batches, and product incoming quantities listed on the pallet list with the physical product names, product batches, and product incoming quantities on the physical pallets. If there are differences, the audit fails and the physical pallets shall be readjusted until there are no differences between the pallet list and the physical pallets.

[0075] In step S203, after the audit is qualified, a transfer task shall be created based on the qualified pallet list and the transfer task shall be sent to the automated guided vehicle (AGV); the transfer task includes moving the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform. For details, please refer to Figure 1 step S103 of the illustrated embodiment, which will not be elaborated here.

[0076] In step S204, control the AGV to execute the transfer task, so that the AGV moves the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform for pallet stretch wrapping. For details, please refer to Figure 1 step S104 of the illustrated embodiment, which will not be elaborated here.

[0077] In step S205, after the physical pallets are stretch wrapped, control the AGV to move the stretch wrapped physical pallets to the surplus material return port for scanning and then send them into the corresponding automated storage and retrieval system (AS / RS).

[0078] Specifically, the above step S205 includes:

[0079] In step S2051, perform an external inspection on the stretch wrapped physical pallets at the surplus material return port to determine whether they are qualified.

[0080] Specifically, the external inspection includes whether the packaging of the stretch wrapped physical pallets is neat and standard, and whether there is factory inspection and market supervision, etc. When the packaging of the stretch wrapped physical pallets is neat and standard and there is factory inspection and market supervision, it is determined that the external inspection is qualified.

[0081] In step S2052, when the external inspection is qualified, scan the physical pallets after the external inspection is qualified and control the AGV to move the physical pallets to the corresponding AS / RS.

[0082] Specifically, when the external inspection is qualified, use a PDA bar code scanner to scan the physical pallets after the external inspection is qualified, and the warehouse control system (WCS) controls the AGV to move the physical pallets to the corresponding AS / RS according to the control instructions of the packaging material procurement and supply control center.

[0083] Step S2053: Rectify the physical tray with unqualified appearance inspection until the appearance inspection is qualified, scan the physical tray after the appearance inspection is qualified, and control the automated guided vehicle (AGV) to transport the physical tray to the corresponding automated storage and retrieval system (AS / RS).

[0084] Specifically, rectify the physical tray with unqualified appearance inspection until the appearance inspection is qualified, use a PDA barcode scanner to scan the physical tray after the appearance inspection is qualified, and the warehouse control system (WCS) controls the AGV to transport the physical tray to the corresponding AS / RS according to the control instructions from the packaging material procurement and supply control center.

[0085] The method for realizing buffer area warehousing based on an AGV provided in this embodiment compares the tray list with the physical tray. When there is no difference between the tray list and the physical tray, the audit is qualified; when there is a difference between the tray list and the physical tray, the audit is unqualified, and the physical tray is readjusted until there is no difference between the tray list and the physical tray, so that the tray list and the physical tray correspond one by one, providing a non-differential data basis for the subsequent accurate warehousing of the physical tray. Conduct an appearance inspection on the physical tray after the winding film is completed at the surplus material return port to determine whether it is qualified, ensuring that the warehoused physical trays are neat and standardized. When the appearance inspection is qualified, scan the physical tray after the appearance inspection is qualified, and control the AGV to transport the physical tray to the corresponding AS / RS. The use of an AGV realizes the purpose of automatic warehousing and improves the efficiency of warehouse operation.

[0086] In this embodiment, a method for realizing buffer area warehousing based on an AGV is provided, which can be used in a warehousing system. The warehousing system includes a winding film platform, a surplus material return port, and multiple AS / RSs. Each AS / RS includes multiple shelves, and each shelf includes multiple storage locations. Figure 3 It is a flowchart of the method for realizing buffer area warehousing based on an AGV according to an embodiment of the present invention, as Figure 3 shown. This process includes the following steps:

[0087] Step S301: Obtain the tray list to be warehoused. For details, please refer to Figure 1 step S201 of the embodiment shown here, which will not be elaborated further.

[0088] Step S302: Audit the tray list to be warehoused based on preset audit conditions. For details, please refer to Figure 1 step S202 of the embodiment shown here, which will not be elaborated further.

[0089] Step S303: When the audit is qualified, create a transfer task based on the audited tray list and send the transfer task to the AGV; the transfer task includes transporting the physical tray in the tray buffer area on the tray list to the winding film platform. For details, please refer to Figure 1Step S203 of the illustrated embodiment will not be elaborated herein.

[0090] Step S304, control the automated guided vehicle (AGV) to perform the task of relocating the inventory, so that the AGV transports the physical pallets in the pallet buffer area on the pallet list to the stretch wrapping platform for pallet stretch wrapping. For details, please refer to Figure 1 Step S204 of the illustrated embodiment will not be elaborated herein.

[0091] Step S305, when the physical pallet stretch wrapping is completed, control the AGV to transport the physically stretch-wrapped pallets to the surplus material return port for scanning and then send them to the corresponding automated storage and retrieval system (AS / RS). For details, please refer to Figure 1 Step S205 of the illustrated embodiment will not be elaborated herein.

[0092] Step S306, allocate the AS / RS shelves for the physically scanned-in pallets and generate the inbound feedback result.

[0093] Specifically, the above step S306 includes: allocating the physically scanned-in pallets to the corresponding preset target storage locations and generating the inbound feedback result.

[0094] Specifically, the preset target storage locations are set according to the corresponding storage location numbers in the preset pallet owner comparison table. The packaging material procurement control center also includes a stacker crane. Under the control instruction of the packaging material procurement control center, the warehouse control system (WCS) controls the stacker crane to transport the physically scanned-in pallets to the corresponding target storage locations on the corresponding shelves according to the corresponding storage location numbers and owner information in the preset pallet owner comparison table. The warehouse control system (WCS) generates the inbound feedback result based on the target storage locations and transmits it to the warehouse management system (EWM).

[0095] Step S307, update the AS / RS inventory information based on the inbound feedback result.

[0096] Specifically, the warehouse management system (EWM) updates the product inventory information in the preset pallet owner comparison table according to the inbound feedback result transmitted by the warehouse control system (WCS), so that the product inventory is transferred from the pallet buffer area to the AS / RS, and the product physicals correspond one-to-one with the product inventory.

[0097] Step S308, clean the pallet buffer area and release the pallet positions in the buffer area.

[0098] Specifically, when all the physical pallets have been stored in the warehouse, inform the packaging production department to clean the pallet buffer area and release the pallet positions in the buffer area.

[0099] The method for realizing buffer storage into the warehouse based on an automated guided vehicle (AGV) provided in this embodiment allocates the physical pallets scanned for storage to the corresponding preset target storage positions on the shelves of the automated warehouse, generates an inbound feedback result, and achieves the purpose of accurately storing the physical pallets. Generating the inbound feedback result provides a data basis for subsequent product inventory counting, further improving the efficiency of warehouse operations. Updating the inventory information of the automated warehouse based on the inbound feedback result ensures that the inventory information of the automated warehouse is consistent with the physical inventory of the warehouse products. Cleaning the pallet buffer area releases the pallet positions in the buffer area, improving the utilization rate of the pallets.

[0100] As one or more specific application embodiments of the embodiment of the present invention, in combination with Figure 4 The method for realizing buffer storage into the warehouse based on an AGV of the present invention is further described as shown in Table 1 below:

[0101] Table 1

[0102]

[0103]

[0104]

[0105] The method for realizing buffer storage into the warehouse based on an AGV provided in this embodiment is initiated by the packaging production department for an inbound storage application. After the packaging material procurement control center verifies and approves, the warehouse keeper in the packaging material procurement center uses a handheld terminal or initiates a transfer requirement for inbound storage from the pallet buffer area on the computer side. The EWM (Extended Warehouse Management) creates a task and transmits it to the WCS (Warehouse Control System). After the AGV receives the handling instruction from the WCS and passes through the stretch wrapping machine according to the set path, it moves the pallet to the waste material return port. After the pallet passes the external inspection and scanning normally, it is transported to the first-floor inbound port for storage and shelving through the conveyor line. The EWM updates the inventory information according to the shelving result feedback by the WCS. Through the integration of the EWM system and the WCS system in the packaging material procurement control center, the automation of in-warehouse transfer in the warehouse is realized, improving the warehouse operation efficiency and reducing the labor cost.

[0106] In this embodiment, a device for realizing buffer storage into the warehouse based on an AGV is also provided. This device is used to implement the above-mentioned embodiment and preferred implementation manners, and those that have been described will not be repeated.
