Description

Technical Field

[0001] The present invention relates to the technical field of warehousing and logistics, and in particular to a cargo space allocation method of a three-dimensional warehouse for storing automobile parts beside a production line. Background Art

[0002] In automobile manufacturing, the standardization and automation of parts transportation and distribution have always been the core key factors for the rapidity and low cost of automobile manufacturing. With the development of the automobile logistics industry, the demand for flexible production of workshop logistics processes has increased sharply. With the increase in the production of different models under a single production line, the limited storage area of ​​line-side parts has become the main factor restricting logistics costs. In the distribution process of the assembly line, in order to meet the needs of co-production of multiple models, major OEMs usually sort the parts that do not have sufficient line-side placement according to the scanning points under the coating, and then supply them to the line through tools or pallet trucks. The primary and secondary supply operations require a large number of operators to complete, and the repetitive operations and actions are simple, with low added value. At the same time, the physical operation links of logistics are increased, which lengthens the length of the entire logistics chain, resulting in high overall logistics costs.

[0003] The existing multi-layer inclined shelves are mainly limited by the height of workers picking up goods. The number of shelves is usually limited to 3 layers or less. The parts storage space and shelf depth are limited, and the utilization rate of the production line side space is poor. At present, there are some automated equipment, which are mainly used in the warehousing field. They are large in size, complex in structure, and inconvenient to operate. They can hardly be directly used on the production line side of the workshop. Personnel are required to carry out secondary distribution to the designated workstations of the production line. It cannot actually solve the problem of insufficient storage space on the line side, and the equipment cost is high.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0005] The embodiment of the present invention provides a method for allocating cargo space in a stereoscopic warehouse for storing automobile parts along a production line, so as to at least solve the technical problems of high logistics cost and low efficiency caused by poor utilization of space along the existing stereoscopic warehouse.

[0006] According to one aspect of an embodiment of the present invention, there is provided a method for allocating cargo spaces in a three-dimensional warehouse for storing automotive parts along a production line, comprising: acquiring data information of various instruments, wherein the instruments are used to transport materials to be shipped out of the warehouse and to be shipped in; determining the number and size of storage boxes corresponding to the various instruments based on the data information of the various instruments; and establishing a three-dimensional warehouse based on the number of storage boxes and the average value of the operating parts, combined with the rules for reserving cargo spaces for inverted boxes and cargo space address codes.

[0029] Figure 1 1 is a flow chart of a method for allocating cargo space in a three-dimensional warehouse for storing automobile parts along a production line according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0030] Step S10, obtaining data information of various tools, wherein the tools are used to transport materials to be shipped out of the warehouse and to be shipped in;

[0031] In step S10, it is necessary to collect information about all equipment used to transport materials, including but not limited to pallets, bins, mother equipment, and any other containers used to store and transport materials to be stored or shipped. Information collection should cover key attributes of the equipment such as size (length, width, height), load capacity, durability, material, shape, etc.

[0032] Step S12, based on the data information of various appliances, determining the number and size of storage boxes corresponding to various appliances;

[0033] In step S12, the data information of various utensils must first be carefully analyzed and processed. The data information includes but is not limited to the length, width, and height of the utensil, as well as the load-bearing capacity and shape characteristics of the utensil. The utensils are classified according to their size, for example, utensil length classification, utensil width classification, etc. For the original size of the carton 600<utensil length (mm) ≤ 800, the number of storage boxes is counted, and for each size classification, the number of utensils belonging to this category is counted. The size of the parent utensil (large storage container for loading multiple storage boxes) is clarified, for example, 800*650mm. The formula is used to calculate the number of storage boxes that each parent utensil can carry: (parent utensil long side size / utensil long side size) * (parent utensil wide side size / utensil wide side size), and the number of carrying boxes is rounded down. The size specifications of the storage boxes are determined by the calculated number of storage boxes and the size distribution of the utensils.

[0034] Step S14, based on the number of storage boxes and the average value of the operating parts, combined with the box reserving rules and the address coding of the storage location, a three-dimensional warehouse is established.

[0035] In step S14, the average value of the operating part generally refers to the average value of the size or weight of the tool that the operator can comfortably and efficiently handle when handling or operating the tool, taking into account ergonomic factors. For example, considering the width range of tools that workers can usually operate comfortably, 0-150mm is defined as the average size range of the operating part, which helps to design the size of the warehouse cargo space to ensure that workers can easily place or take out the tools.

[0036] According to the number of storage boxes, plan the overall number of cargo spaces in the stereoscopic warehouse. Taking into account the vertical space utilization of the stereoscopic warehouse, the cargo spaces are distributed on multi-layer shelves. Each shelf is designed into several rows and columns to accommodate storage boxes of different sizes and ensure sufficient storage space. Considering the average value of operating parts (such as the size of the mother device), the size and layout of the cargo spaces are designed to ensure that the mother device can be easily put in and taken out, while optimizing the internal space and reducing invalid space. According to the rules for reserving cargo spaces for box dumping, one-sixth or one-eighth of the number of cargo spaces on each layer of box dumping is reserved to ensure that there is enough space for operation when box dumping is required. The overall reservation of box dumping cargo spaces should be one-third of the overall planned number of cargo spaces. This reservation can ensure that the box dumping process will not be hindered due to insufficient cargo spaces during peak hours or when operations are complex.

[0037] The cargo location address coding is to create a unique address code for each cargo location in the stereoscopic warehouse. The coding rules are layer number / lane / group / location number. For example, the code 3 / 210112 means the 0112th cargo location on the third floor and lane 21. The address coding system should also include direction information, such as left 1 right 2, inside 7 outside 8, to facilitate operators and automated equipment to identify the specific location of the cargo location.

[0038] Based on the above steps S10 to S14, in the embodiment of the present invention, a data-driven approach is adopted to analyze and integrate the size and quantity information of various handling tools, combined with the box-turning cargo space reservation rules and cargo space address coding, to achieve the purpose of scientifically and rationally allocating cargo spaces in the stereoscopic warehouse, thereby achieving the technical effect of improving the production line storage efficiency and space utilization, optimizing the operation process, reducing the frequency of box-turning operations, thereby reducing manpower and equipment costs, and improving production efficiency. In addition, the technical problem of high logistics costs and low efficiency caused by poor space utilization of existing stereoscopic warehouses is solved.

[0039] Furthermore, based on the number of storage boxes and the average value of the operating parts, combined with the rules for reserving cargo spaces for box reversing and the cargo space address coding, a three-dimensional warehouse is established, including: obtaining at least one of the average width value, average height value and average thickness value in the average value when the operating parts perform material handling, wherein the operating parts include one of the palm of the operating object and the palm of the manipulator; based on the number of storage boxes and at least one of the average width value, average height value and average thickness value, combined with the rules for reserving cargo spaces for box reversing and the cargo space address coding, a three-dimensional warehouse is established.

[0040] Specifically, at least one of the average width value, average height value and average thickness value in the average value when the operating part performs the material handling state is obtained. According to ergonomic data, the average width of the operator's palm is about 70mm. The comfortable operating height range of human hands is generally below 800mm. Considering the convenience of manual operation, the average thickness value of the material should be considered to be around 100mm. Assume that the information of parts to be stored in a stereoscopic warehouse beside a production line has been collected, and the number of storage boxes is determined to be 34,560. According to statistics, the average size of the original box parts is 300mm wide, 200mm high, and 150mm thick, and the average size of the turnover box (used as a mother device) is 500mm wide, 400mm high, and 200mm thick. Based on the number of storage boxes and the size of parts, plan the number of layers, number of lanes, shelf depth and other parameters of the warehouse. Considering the average width of the human hand, design the width of the cargo space suitable for the worker's operation; based on the average thickness and height values, design the depth and height of the shelf to ensure that the worker does not exceed the comfort range when operating, while maximizing the space utilization. Reserve a cargo space for unloading containers on each floor to ensure that there is enough space for unloading containers in accordance with the rules. Assign a unique address code to each cargo space to facilitate accurate positioning and operation by automated equipment and workers.

[0041] In a specific embodiment, it is assumed that there are 4 floors in the warehouse, each floor has 6 lanes, each lane has 10 groups of cargo locations, and each group of cargo locations contains 100 cargo locations. Based on these parameters, the total number of cargo locations is 24,000 (4 floors * 60 lanes * 10 groups * 100 cargo locations / group), and the reserved cargo locations for unloading containers on each floor are one-sixth or one-eighth of the total number of cargo locations. Taking the third floor as an example, assuming that the number of cargo locations on each floor is 6,000 (60 lanes * 10 groups * 100 cargo locations / group), then the number of cargo locations reserved for unloading containers on the third floor is 750 (6,000 cargo locations / 8). In the overall planning, the reserved cargo spaces for unloading containers are one-third of the total cargo spaces, that is, 8,000 cargo spaces. According to the coding rules, for example, the first cargo space of the first group in the first aisle on the first floor is coded as 1 / 010001 to ensure that the cargo space width is suitable for manual operation. At the same time, the shelf height is designed to be below 800mm to accommodate the height range for workers to stand and operate, ensuring work safety and efficiency.

[0042] Through the above steps, combined with the average values ​​of the operating parts (width, height, thickness, etc.), the design of the three-dimensional warehouse can be more humane, which not only improves the effective utilization of the storage space, but also ensures the comfort and safety of the operators, thereby achieving the purpose of optimizing logistics costs and improving logistics efficiency.

[0043] Furthermore, data information of various instruments is obtained, and based on the data information of the various instruments, the number and size of storage boxes corresponding to the various instruments are determined, including: obtaining data information of various instruments, wherein the data information includes instrument length information and width information; grouping instruments of different lengths based on the instrument length information to obtain a plurality of groups of data of a first instrument group with different lengths, wherein the length values ​​of the instruments in each group of the first instrument group do not overlap with each other; grouping instruments of different widths based on the instrument width information to obtain a plurality of groups of data of a second instrument group with different widths, wherein the width values ​​of the instruments in each group of the second instrument group do not overlap with each other; determining the number and size of storage boxes based on the length information and quantity information of the first instrument group and the width information and quantity information of the second instrument group.

[0044] Based on the length information of the tools, tools of different lengths are divided into different length data first tool groups. For example, tools with a length of 0 mm to 200 mm can be grouped into one group, tools with a length of 201 mm to 400 mm can be grouped into another group, and so on, until the length range of all tools is covered. Make sure that the length values ​​in each group do not overlap, which means that each tool length belongs to only one group.

[0045] Similarly, based on the appliance width information, appliances of different widths are divided into different width data second appliance groups. For example, appliances with a width of 100 mm to 150 mm are divided into one group, appliances with a width of 151 mm to 300 mm are divided into another group, and appliances with a width of 301 mm to 500 mm are divided into a third group. Similarly, ensure that the width values ​​in each group do not overlap to avoid confusion of appliance size information.

[0046] For each length and width grouping, count the number of utensils in the group, which will determine how many storage boxes are needed to accommodate these utensils. For example, if there are 2,000 utensils with a length of 201mm to 400mm and a width of 151mm to 300mm, assuming that the size of the parent utensil (storage box) is 800mm*650mm, the maximum number of utensils that each storage box can carry is: in the length direction, 800mm / 400mm=2, rounded down to 2. In the width direction, 650mm / 300mm≈2, rounded down to 2. Therefore, each storage box can carry 4 utensils. In order to accommodate this batch of 2,000 utensils, 500 storage boxes need to be prepared (2000 / 4=500), and the specific storage box size is further calculated to ensure maximum space utilization and operator convenience. For example, the size of the storage box can be designed to be 400mm*300mm to adapt to the size of the utensils in the above grouping.

[0047] The above steps can be optimized by grouping to more flexibly adapt to the storage needs of appliances of different sizes and improve the adaptability and utilization rate of the warehouse.

[0048] Furthermore, based on the length information and quantity information of the first instrument group and the width information and quantity information of the second instrument group, the number and size of the storage boxes are determined, including: obtaining the maximum length value of each type of instrument in the first instrument group and the maximum width value of each type of instrument in the second instrument group; based on the maximum length value, maximum width value and quantity information of each type of instrument, determining the size range and the number and size of each type of storage boxes.

[0049] The tools are grouped according to the length information to obtain multiple sets of first tool groups with different length data. For example: Group 1: 0≤tool length≤200mm, tool quantity: 1000; Group 2: 200<tool length≤400mm, tool quantity: 2000; Group 3: 400<tool length<600mm, tool quantity: 1000.

[0050] The tools are grouped according to the width information to obtain multiple sets of second tool groups with different width data, for example: Group 1: 0≤tool width≤150mm, number of tools: 1000; Group 2: 150<tool width≤300mm, number of tools: 2000; Group 3: 300<tool width<500mm, number of tools: 1000.

[0051] Based on the above grouping, determine the maximum length and maximum width of each group of utensils: Maximum value of length group 1: 200mm; Maximum value of length group 2: 400mm; Maximum value of length group 3: 599mm (assuming it is close to 600mm); Maximum value of width group 1: 150mm; Maximum value of width group 2: 300mm; Maximum value of width group 3: 499mm (assuming it is close to 500mm). Set the size of the parent utensil to 800mm*650mm. For the utensils of length group 1 and width group 1, calculate the size and number of storage boxes: Storage box size: 200mm*150mm (based on the maximum length and width of the utensil) For group 1 utensils, due to size adaptation, directly use the number of utensils 1000 as the number of storage boxes. For utensils of length group 2 and width group 2: the maximum length value is 400mm, the maximum width value is 300mm, and the storage box size is designed to be 400mm*300mm. Calculate the number of storage boxes: 2000 The number of utensils is divided by the number of utensils contained in each box. Since the size of the storage box can accommodate 2 rows and 2 columns (a total of 4) of utensils, the number of storage boxes is 500 (2000 / 4=500). For utensils with 3 length groups and 3 width groups: the maximum length value is 599mm, and the maximum width value is 499mm. Considering the standardization of storage boxes and the convenience of operators, the design size of the storage box for larger-sized utensils is 600mm*500mm. Calculate the number of storage boxes: 1000 utensils divided by the number of utensils contained in each box. For utensils of this size, the storage box can only accommodate 1 utensil, so the number of storage boxes is 1000. Taking all groupings into consideration, the final number of storage boxes is 2500.

[0052] Through the above steps, combined with the maximum length value, maximum width value and quantity information of the equipment, the size range and specific quantity of each type of storage box can be scientifically and reasonably determined, thereby achieving efficient use of space and convenience of operation in the design of the stereoscopic warehouse.

[0053] Furthermore, before determining the number and size of storage boxes corresponding to various instruments based on the data information of various instruments, it includes: determining the mother box information based on the data information of various instruments, wherein the mother box information includes the inner edge size of the mother box, the mother box loading quantity and the mother box usage.

[0054] Specifically, the determination of the inner edge dimensions of the mother box refers to the available space dimensions inside the mother box, which is directly related to the number and size of storage boxes that the mother box can carry. When determining the inner edge dimensions of the mother box, the overall layout of the warehouse, the limitations of the handling equipment, and the convenience of the operator should be taken into account. The calculation of the mother box loading quantity is based on the inner edge dimensions of the mother box and the dimensions of the storage box, and the number of storage boxes that each mother box can carry is calculated. Determination of the mother box usage The mother box usage refers to the calculation of the total number of mother boxes that need to be used based on the number of utensils that need to be stored.

[0055] According to a specific embodiment, the size of the equipment is length ≤ 200mm, width ≤ 150mm, quantity: 5000, assuming 800mm*650mm, this size is based on the consideration of warehouse space utilization and the operating range of the handling equipment. For the above equipment, each mother box can load 6 storage boxes (2 rows and 3 columns layout), and the mother box usage of the equipment is 5000 / 6≈833. The mother box information can be determined based on the data information of the equipment, including the inner edge size of the mother box, the number of storage boxes that can be loaded in each mother box, and the overall mother box usage required, which provides a basis for the subsequent determination of the number and size of storage boxes. This not only ensures the efficient use of storage space, but also takes into account the convenience of operation of operators. At the same time, through the standardized mother box design, the standardization and automation level of logistics operations are improved.

[0056] Furthermore, based on the average value of the number of storage boxes and operating parts, combined with the rules for reserving cargo spaces for box dumping and cargo space address codes, a three-dimensional warehouse is established, including: obtaining the number of cargo spaces and the total number of cargo spaces on each layer of the pre-established three-dimensional warehouse; upon determining that the ratio of the number of reserved cargo spaces for box dumping on each layer to the number of cargo spaces on the corresponding layer meets a first preset value, based on the average value of the number of storage boxes and operating parts, combined with the cargo space address codes, a three-dimensional warehouse is established.

[0057] Specifically, the preliminary planning determines the number of layers of the three-dimensional warehouse, the number of lanes on each layer, and the number of cargo spaces in each lane. For example, assuming that the preliminary planning is 10 layers, each layer has 20 lanes, and each lane has 150 cargo spaces, then the total number of cargo spaces is 30,000 cargo spaces. According to the rules for reserving cargo spaces for inverted boxes, the number of inverted box cargo spaces that need to be reserved on each layer is calculated. For example, if the first preset value is one-sixth of the number of reserved cargo spaces on each layer, then the number of inverted box cargo spaces reserved on each layer is 500 of the 3,000 cargo spaces. The verification of the first preset value checks whether the ratio of the number of reserved inverted box cargo spaces to the number of cargo spaces on the corresponding layer meets the first preset value (one-sixth or one-eighth). If it meets the requirements, the next step of warehouse establishment can be entered; if it does not meet the requirements, the number of layers, lanes or cargo spaces of the warehouse needs to be adjusted to ensure that the number of reserved inverted box cargo spaces is consistent with the first preset value. On each layer and each lane of the warehouse, the shelves are built and the cargo spaces are divided according to the planned cargo space size and quantity. Ensure that the unloading location is reserved according to the rules, and implement address coding for each location to facilitate positioning of automated equipment and manual operations.

[0058] Through the above steps, combined with the number of storage boxes, the average value of the operating parts, the rules for reserving the cargo space for the box, and the cargo space address coding, a three-dimensional warehouse can be scientifically and rationally established to achieve high-density storage, efficient logistics operations, and precise cargo space management. In addition, this planning method can also adapt to possible changes in storage needs in the future and provide flexible adjustment space.

[0059] Further, when it is determined that the ratio of the reserved number of box dumping on each layer to the number of cargo locations on the corresponding layer meets the first preset value, a three-dimensional warehouse is established based on the average value of the number of storage boxes and the operating parts in combination with the cargo location address codes, including: when it is determined that the ratio of the reserved number of box dumping to the total number of cargo locations meets the second preset value, and the ratio of the reserved number of box dumping on each layer to the number of cargo locations on the corresponding layer meets the first preset value, a three-dimensional warehouse is established based on the average value of the number of storage boxes and the operating parts in combination with the cargo location address codes.

[0060] Specifically, the first preset value refers to the ratio of the number of cargo spaces reserved for unloading containers on each floor to the total number of cargo spaces on that floor, which is usually one-sixth or one-eighth; the second preset value refers to the ratio of the number of cargo spaces reserved for unloading containers in the entire warehouse to the total number of cargo spaces, which is usually one-third.

[0061] In a specific embodiment, it is assumed that the stereoscopic warehouse is designed as 10 layers, each layer has 60 lanes, and each lane has 50 cargo spaces, then the total number of cargo spaces is 30,000 (10 layers, 60 lanes, 50 cargo spaces / lane). According to the second preset value, one-third of the cargo spaces in the entire warehouse are reserved as reserved cargo spaces for box dumping, that is, 10,000 cargo spaces. The remaining 20,000 cargo spaces are used for storage. Further, according to the first preset value, one-sixth of the cargo spaces are reserved on each layer as reserved cargo spaces for box dumping. The total number of cargo spaces on each layer is 3,000 (60 lanes, 50 cargo spaces / lane), and the number of cargo spaces reserved for box dumping on each layer is 500 (3,000 cargo spaces / layer / 6). Therefore, the number of cargo spaces per layer used for storage is 2,500. Based on storage requirements, the total number of storage boxes that need to be stored is 10,000. The average palm width of the operator is 70 mm. According to the average size of the equipment, the storage box size is set to 350 mm, 250 mm, and 200 mm to ensure that all equipment can be adapted. A unique address code is assigned to each cargo location, such as the format of "layer number / aisle / group / location number".

[0062] This method further optimizes the warehouse layout by setting multiple layers of reservation rules, ensuring that the warehouse can maintain efficient operation under different operational requirements.

[0063] Furthermore, based on the average value of the number of storage boxes and operating parts, combined with the rules for reserving cargo spaces for box turnovers and cargo space address codes, a three-dimensional warehouse is established, including: based on the average value of the number of storage boxes and operating parts, combined with the rules for reserving cargo spaces for box turnovers and cargo space address codes, an execution system and a host system in the three-dimensional warehouse are established.

[0064] Execution System (WCS-Warehouse Control System): Responsible for specific operations, such as elevators, shuttles, etc. Ensure that they operate according to the predetermined logic and perform operations such as warehousing, outbound storage, and unloading.

[0065] Upper system (WMS-Warehouse Management System): performs task allocation and data management for the entire warehouse, processes instructions from PLP, and provides task and data support for WCS.

[0066] Figure 2 This is a schematic diagram of a three-dimensional warehouse system for storing automobile parts along a production line according to one embodiment of the present invention. The details are as follows:

[0067] As the task layer, FAW Logistics WMS receives PLP orders, issues task allocation, and connects to the box line WCS system, shuttle car WCS system, elevator WCS system, and ground AGV (Automated Guided Vehicle) regional WCS system. Tasks are issued to business execution equipment, and hardware equipment, collection equipment, and transportation equipment are controlled by the WMS system.

[0068] AGV (Automated Guided Vehicle) is an unmanned vehicle that can automatically complete material handling tasks. It is widely used in industrial automation, logistics warehousing, manufacturing plants and other scenarios. AGV receives material handling, storage, picking and other task instructions through the interface with the upper system (such as WMS, Warehouse Management System). According to the instructions, AGV can automatically go to the material location, load the material, and transport it to the specified target location.

[0069] PLP system (Production Logistics Planning), that is, production logistics planning system, is responsible for binding the mother device and the original box.

[0070] FAW Logistics WMS: PLP three-dimensional warehouse global data transmission, the received inbound and outbound orders are allocated to aisles, elevators, shuttles, storage locations, sorting tables, and picking ports.

[0071] Box line WCS: Execute tasks assigned by WMS, including weighing and abnormal port processing.

[0072] Elevator WCS: Executes tasks assigned by WMS and performs inbound and outbound tasks for parts assigned to this elevator.

[0073] Shuttle car WCS: executes the inbound and outbound tasks assigned by WMS and handles exceptions.

[0074] It needs to be further explained that Figure 4 This is an information flow chart of a method for allocating cargo space in a three-dimensional warehouse for storing automobile parts along a production line according to another embodiment of the present invention. The specific process steps are as follows:

[0075] Warehousing: The upper system PLP issues material warehousing instructions; the WMS system receives the warehousing instructions from the PLP system; the WMS system issues instructions to the WCS system; the materials are weighed at the entrance, and the materials with abnormal weighing (overweight) are bounced to the abnormal entrance. The PLP system is manually untied and re-tied and weighed again. If there is no abnormality, the material goes straight; if the scanning is abnormal - the kanban is damaged, the PLP will re-print the kanban, and if the scanning is abnormal - the kanban is not damaged, the WMS system will re-print the secret code; the WCS system issues instructions to the WCS system of the conveyor elevator and the WCS system of the shuttle car, and the materials are put into the designated warehouse location according to the aisle number and storage location issued by the WMS system.

[0076] There are two forms of parts entering the three-dimensional warehouse. One is to enter the warehouse in original boxes, that is, directly scan and enter the warehouse according to the arrival form. The other is to enter the warehouse in turnover boxes, which are used as mother equipment. That is, the arrived parts are bound to the turnover boxes before entering the warehouse, and the mother equipment circulates in the three-dimensional warehouse. Parts are transported in and out of the warehouse through four-way shuttles, material box elevators and conveyor lines. The three-dimensional warehouse involves the PLP system, WMS storage system, shuttle car WCS system, elevator WCS system, box line WCS system (including barcode readers). The PLP system is the main engine plant warehouse management system. The WMS storage system needs to be newly built for this project. It is used to undertake the entry and exit task information of the main engine plant PLP system, and transmit this information to the shuttle car WCS system and the box line WCS system after logical analysis, as well as the ground AGV area WCS system.

[0077] Large-item outbound delivery: The large-item area has a barcode reader, a weighing device, and a dimension measuring device. When a large-item box is put on the conveyor line, the box line WCS system scans the barcode of the goods and performs weight and dimension inspections. If the goods meet the transmission requirements, the conveyor line WCS system sends an application to the WMS system. The WMS system determines whether the goods are allowed to be transferred based on the outbound delivery task assigned by the PLP system, and feeds back the results to the box line WCS system. The box line WCS system transfers and diverts the goods according to the assigned destination address.

[0078] Ordinary outbound delivery: The upper PLP system issues outbound delivery instructions; the WMS system receives the instructions and determines the outbound delivery type (large items or vertical warehouse) based on the target address;

[0079] If it is a large item outbound, the box line will be directly transported to the final assembly exit; if it is a vertical warehouse outbound, the warehouse location will be allocated according to the outbound principle and transmitted to the shuttle car WCS system. The shuttle car will take the material out of the warehouse. At this time, it is necessary to feedback the outbound completion information of the WMS system. The conveyor line WCS system will transport the material to the designated location according to the picking platform issued by the WMS system; if the mother device has remaining parts that need to be returned to the warehouse after picking, the WMS system needs to issue a return instruction; if the mother device has remaining parts that need to be returned to the warehouse after picking, the WMS system needs to issue a return instruction; the mother device will be returned to the warehouse entrance empty. The mother device is scanned and unbound by the WMS system, and the mother device is sent back to the conveyor belt after picking, and the parts are sent to the outbound conveyor belt; the material determines the material's travel route according to the outbound path issued by the WMS system; the box line WCS system uses a barcode reader before the material enters the final assembly to determine which final assembly station to enter; if the code reading fails, it enters the abnormal exit.
