Description

Technical Field

[0001] The present invention relates to the technical field of automated production line production, and in particular to a production line feeding and replenishment method, system and computer equipment. Background Art

[0002] In the operation of manufacturing enterprises, there will be special warehouses for storing production packaging materials. As the products are produced and shipped, the inventory of packaging materials will be consumed. In order to meet the needs of continuous operation, packaging materials must be replenished. The circulation path of ordinary packaging materials is: supplier-three-dimensional warehouse-buffer area-production line, and the circulation path of glass bottles is: supplier-glass bottle warehouse-production line. The replenishment time and replenishment quantity at each stage are key decisions. If the replenishment is too much, it will increase capital occupation and the risk of inventory stagnation and explosion. If the replenishment is too little, it will lead to a lack of packaging materials and affect production efficiency, which is not good for the operation of the enterprise. The existing technical solutions usually replenish stocks based on human experience, but the replenishment time and replenishment quantity are not reasonable enough, resulting in the problem that the production line cannot produce continuously, wasting production line resources, reducing production efficiency, and failing to achieve refined management of the production line packaging material replenishment process. Summary of the Invention

[0003] In view of this, the present invention provides a production line material supply and replenishment method, system and computer equipment to solve the problem of unreasonable packaging material replenishment in existing production lines.

When a material request needs to be initiated, submit the material request information;

[0006] Receive material request information and create pallet material handling tasks based on the request information;

[0007] Issue handling instructions to automatic handling equipment based on pallet material handling tasks;

[0008] Based on the handling instructions, the automatic handling equipment is controlled to remove the required pallet materials from the preset buffer area, and based on the removed pallet materials, the automatic handling equipment is controlled to directly connect with the production line to complete the material replenishment and handover.

[0009] The present invention provides a production line material supply and replenishment method, which obtains production line cache information and a preset time period production work order, and uses an MES algorithm to determine whether to initiate a material request based on the production line cache information and the preset time period production work order, and submits the material request information when it is necessary to initiate a material request; then creates a pallet material handling task based on the material request information; then issues a handling instruction to an automatic handling device based on the pallet material handling task; finally, controls the automatic handling device to remove the required pallet material from a specified preset cache area based on the handling instruction, and controls the automatic handling device to directly connect with the production line to complete material replenishment and handover based on the removed pallet material, thereby generating a material request according to the actual material demand of the production line, and monitoring the entire process of task creation, instruction issuance, material removal and material loading according to the material request, thereby improving the accuracy and real-time performance of material replenishment, ensuring that production demand is met while reducing invalid inventory and reducing inventory resource waste, further improving production efficiency, preventing production line shutdowns, ensuring continuous output of the production line, making the replenishment process of each material more reasonable, and solving the problem of unreasonable replenishment of packaging materials in existing production lines.

[0010] In an optional embodiment, the production line includes a production chain, and a plurality of pallet positions are provided on the production chain as a pallet buffer area; obtaining the production work order and production line buffer information for a preset time period includes:

[0011] Obtain the production plan for the preset time period and collect the photoelectric signals transmitted by each pallet position on the production chain;

[0012] Generate production work orders based on the production plan for a preset time period;

[0013] The number of pallets on the pallet position is determined based on the photoelectric signal, and production line cache information is generated based on the number of pallets.

[0014] The present invention provides a production line material supply and replenishment method, which generates a production work order through a production plan for a preset time period, determines the number of pallets on the pallet position based on a photoelectric signal, and generates production line cache information based on the number of pallets. It can accurately obtain the production work order and the first-level cache information of the production line, providing conditions for subsequent initiation of material call requests.

[0015] In an optional embodiment, an MES algorithm is used to determine whether to initiate a material request based on the production line cache information and the production work order in a preset time period.

[0017] The MES algorithm is used to calculate the remaining completion quantity and the completed quantity based on the number of remaining pallets and the number of used pallets. The MES algorithm is an artificial intelligence-based calculation algorithm.

[0018] Material calculations are performed using an MES algorithm based on the planned completion quantity, completed quantity, and remaining completion quantity. When the sum of the completed quantity and the remaining completion quantity is less than the planned completion quantity and there are vacant pallet slots on the production chain, a material request is initiated and material request information is submitted based on the request. The material request information includes the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the required material number, and the required material quantity.

[0019] When the sum of the completed quantity and the remaining completed quantity is greater than or equal to the planned completed quantity, there is no need to initiate a material request.

[0020] The present invention provides a production line material supply and replenishment method, which adopts the MES algorithm and combines the available pallet positions of the production line and the planned completion quantity, completed quantity and remaining completion quantity of the production line to jointly judge whether the production line needs to call for materials. The demand for replenishment of the production line can be accurately judged based on the completion quantity and available pallet positions, and the situation where there are no storage pallets for replenishment can be avoided, thereby ensuring the normal operation of the production line replenishment process.

[0021] In an optional embodiment, creating a pallet material handling task based on the material request information includes:

[0024] The present invention provides a production line material supply and replenishment method, which determines the corresponding preset buffer area inventory location, the pallet number in the preset buffer area and the material number corresponding to the pallet based on the supplier and the required material number, which is beneficial for the supplier of the materials required by the production line and the material number to accurately find the inventory location, pallet number and material number corresponding to the preset buffer area, and accurately creates pallet material handling tasks based on the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the preset buffer area inventory location, the pallet number in the preset buffer area, the material number corresponding to the pallet and the required material quantity, thereby providing conditions for replenishing the preset buffer area to the production line.

[0027] Based on the pallet materials removed from the shelf, the automatic handling equipment is controlled to move the pallet materials to the queue position;

[0028] The automatic handling equipment at the control queue is directly connected to the production line to complete material replenishment and handover.

[0029] In an optional embodiment, the automatic handling equipment at the queue position is controlled to directly connect with the production line to complete material replenishment and handover, including:

[0030] Control the automatic handling equipment at the queue to apply for material loading to the production line;

[0031] When there is a vacant pallet position on the production line, the loading request is determined to be approved, and the automatic handling equipment is controlled to transport the pallet material to the loading point of the production line to complete the material replenishment and handover.

[0032] The present invention provides a production line material supply and replenishment method, which controls the automatic handling equipment based on the handling instructions, the supplier, the inventory location of the preset buffer area, the pallet number in the preset buffer area, the material number corresponding to the pallet and the required material quantity to adopt the first-in material first-out principle and / or the first-expired material first-out principle to remove the corresponding pallet material from the designated preset buffer area, thereby ensuring the first-in first-out principle of the pallet material and improving the availability of the material. The automatic handling equipment on the control queue position is directly connected to the production line to complete the material replenishment and handover without the need for step-by-step feedback, thereby improving the replenishment efficiency, providing conditions for the normal replenishment of the production line, and ensuring the continuity of the production line output.

[0033] In an optional embodiment, the production line supply and replenishment method further includes:

[0034] After the material replenishment handover is completed, the task handover results are fed back step by step;

[0055] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0056] According to an embodiment of the present invention, an embodiment of a production line material supply and replenishment method is provided. 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 a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0057] In this embodiment, a production line material supply and replenishment method is provided, which can be used in the above-mentioned computer equipment. A production line material supply and replenishment system is set in the computer equipment, such as Figure 4 As shown in the figure, the production line feeding and replenishment system includes the MES subsystem (Manufacturing Execution System, production management subsystem), EWM subsystem (Extended Warehouse Management, warehouse management subsystem), WCS subsystem (Warehouse Control System, warehouse control subsystem) and RCS subsystem (Robotic Control System, equipment scheduling subsystem), which communicate in sequence. Figure 1 FIG. 1 is a flow chart of a production line material supply and replenishment method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0058] Step S101, obtain the production line cache information and the production work order of the preset time period, and use the MES algorithm to determine whether to initiate a material request based on the production line cache information and the production work order of the preset time period, and submit the material request information when it is necessary to initiate a material request.

[0059] Specifically, in the operation of a manufacturing enterprise, the production line is located in the packaging material production department, and an MES subsystem is set up in the packaging material production department, where the production line cache information can be defined as first-level cache information. In this embodiment, the preset time period is set to daily, and the preset time period production work order refers to the production work order formed every day according to the enterprise's production plan, and the production work order formed every day according to the enterprise's production plan is stored in the MES subsystem.

[0060] The MES algorithm is not essentially a specific algorithm, but rather a software system used to optimize the manufacturing process. This software system utilizes a variety of algorithms and technologies to implement production plan execution, tracking, monitoring, and feedback. For example, an MES subsystem might use an AI-based algorithm to calculate the relationship between cached information and production order throughput to determine whether a material request is necessary. It might also employ machine learning algorithms for quality prediction and defect detection, or algorithms such as support vector machines (SVMs) for fault prediction.

[0061] The MES subsystem is a production information management system for the execution layer of the manufacturing enterprise's workshop. It connects upper-level management decisions with lower-level production operations. Its main purpose is to track and record the transformation of raw materials to finished products in real time. By capturing data from various sources (including machines, sensors, and operators), it provides accurate and up-to-date information on the status of production activities.

[0062] The MES subsystem obtains the first-level cache information of the production line and the production work order of the preset time period, and uses the MES algorithm to calculate whether the materials in the first-level cache information of the production line can meet the production volume on the daily production work order. When the materials in the first-level cache information of the production line can meet the production volume on the daily production work order, there is no need to initiate a material request. Otherwise, a material request needs to be initiated and the material request information needs to be submitted to the EWM subsystem, such as Figure 5 As shown, the MES subsystem calls the EWM subsystem for materials according to the production rhythm.

[0063] The material request information must include: the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the required material number, and the required material quantity, so that the EWM subsystem can accurately create material handling tasks.

[0064] Step S102: receiving material request information and creating a pallet material handling task based on the material request information.

[0065] Specifically, if Figure 4 and Figure 5 As shown in the figure, the EWM subsystem receives material request information, creates a pallet material handling task based on the information, including the production line loading point, production line name, supplier, required material number, and required material quantity, and sends the pallet material handling task to the WCS subsystem. The pallet material handling task must include information such as the production line's factory location, production line inventory location, production line loading point, production line name, supplier, pre-set buffer storage location, pre-set buffer pallet number, pallet-specific material number, and required material quantity, enabling the WCS subsystem to accurately issue handling instructions to the automated handling equipment.

[0066] Step S103: issuing a transport instruction to the automatic transport equipment based on the pallet material transport task.

[0067] Specifically, the automatic handling equipment is located in the RCS subsystem. The automatic handling equipment can be an Automated Guided Vehicle (AGV), which can realize pallet material handling and transportation.

[0068] The WCS subsystem (Warehouse Control System) is a warehouse control system, a management and control system between the EWM subsystem and the RCS subsystem. The core functions of the WCS subsystem include equipment control and management, task allocation and optimization, workflow control, and data integration and communication.

[0069] The WCS subsystem is used to issue handling instructions to automatic handling equipment based on pallet material handling tasks.

[0070] Step S104 , based on the transport instruction, the automatic transport device is controlled to remove the required pallet materials from the preset buffer area, and based on the removed pallet materials, the automatic transport device is controlled to directly connect with the production line to complete the material replenishment and handover.

[0071] Specifically, the RCS subsystem controls the removal of required pallets from a pre-set buffer based on handling instructions. This information includes the buffer's location, the corresponding pallet number, the material number, and the required quantity. The RCS subsystem is an equipment scheduling system primarily used to manage and optimize the scheduling and operation of automated guided vehicles (AGVs). The RCS subsystem includes a PLC controller, which controls the AGVs' handling and transportation of pallets.

[0072] The preset cache area can be defined as a secondary cache area for storing materials. The secondary cache area is mainly used to replenish the primary cache of the production line, that is, the method of this embodiment is used to carry out the production line replenishment process. When the material in the secondary cache area does not reach the preset threshold, materials can be called from the stereoscopic warehouse for replenishment. Please refer to the relevant technology and will not go into details here.

[0073] like Figure 4 As shown, when the required pallet materials are successfully taken off the preset buffer area, the RCS subsystem controls the unmanned transport AGV to transport the materials to the queue position, and the unmanned transport AGV is directly connected to the production line. When the production line meets the loading conditions, the unmanned transport AGV is controlled to transport the materials directly to the loading point of the production line, without the need to apply for loading step by step, thereby improving the replenishment efficiency.

[0074] The production line material supply and replenishment method provided by this embodiment obtains production line cache information and production work orders for a preset time period, and uses an MES algorithm to determine whether to initiate a material request based on the production line cache information and the production work orders for the preset time period, and submits the material request information when a material request needs to be initiated; then creates a pallet material handling task based on the material request information; then issues a handling instruction to the automatic handling equipment based on the pallet material handling task; finally, based on the handling instruction, controls the automatic handling equipment to remove the required pallet materials from a specified preset cache area, and controls the automatic handling equipment to directly connect with the production line to complete material replenishment and handover based on the removed pallet materials, thereby generating material request according to the actual material demand of the production line, and monitoring the entire process of task creation, instruction issuance, material removal and material loading according to the material request, thereby improving the accuracy and real-time performance of material replenishment, ensuring that production demand is met while reducing invalid inventory and reducing inventory resource waste, further improving production efficiency, preventing production line shutdowns, ensuring continuous output of the production line, making the replenishment process of each material more reasonable, and solving the problem of unreasonable packaging material replenishment in existing production lines.

[0075] In this embodiment, a production line material supply and replenishment method is provided, which can be used in the above-mentioned computer equipment. A production line material supply and replenishment system is set in the computer equipment, such as Figure 4 As shown in the figure, the production line feeding and replenishment system includes the MES subsystem (Manufacturing Execution System, production management subsystem), EWM subsystem (Extended Warehouse Management, warehouse management subsystem), WCS subsystem (Warehouse Control System, warehouse control subsystem) and RCS subsystem (Robotic Control System, equipment scheduling subsystem), which communicate in sequence. Figure 2 FIG. 1 is a flow chart of a production line material supply and replenishment method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0076] Step S201, obtain the production line cache information and the production work order of the preset time period, and use the MES algorithm to determine whether to initiate a material request based on the production line cache information and the production work order of the preset time period, and submit the material request information when it is necessary to initiate a material request.

[0077] Specifically, the production line includes a production chain, and a plurality of pallet positions are provided on the production chain as pallet buffer areas; the above step S201 includes:

[0078] Step S2011: Obtain a production plan for a preset time period and collect photoelectric signals transmitted by each pallet position on the production chain.

[0079] Specifically, the production plan for the preset time period of this embodiment is a daily production plan. Photoelectric sensors are installed on the production chain, which use the photoelectric effect to detect the existence of objects or measure the characteristics of objects, that is, use photoelectric signals to sense whether there are pallet materials on each pallet position.

[0080] Furthermore, the MES subsystem can obtain production plans for preset time periods: By connecting with an enterprise resource planning (ERP) system or production planning management system, it can obtain detailed production plans for preset time periods (such as daily, weekly, or monthly). This production plan includes key information such as product type and planned completion quantity, which serves as the basis for subsequent production activities. For example, the ERP system may obtain the planned completion quantity of product A for the next week: 1,000 units, and 800 units for product B.

[0081] Collecting photoelectric signals from each pallet position along the production chain: Photoelectric sensors are installed at each pallet position along the production chain. These sensors collect real-time information about the pallet position's status and transmit it to the MES subsystem in the form of photoelectric signals. When a pallet passes or stops at a position, the photoelectric signal status changes. By continuously monitoring these signals, the MES subsystem accurately grasps the real-time status of each pallet position.

[0082] Step S2012: Generate a production work order based on the production plan for the preset time period.

[0083] Specifically, a production work order is formed based on the company's daily production plan and stored in the MES subsystem.

[0084] Furthermore, the MES subsystem automatically generates production work orders based on the production plan for the preset time period. The production work order specifies the product type, quantity, estimated production time, and corresponding production line for each production batch. For example, based on the production plan for 1,000 units of product A and 800 units of product B, the MES system generates two production work orders: one for product A, scheduled for production line 1, with 10 batches of 100 units per batch and an estimated completion rate of 2 batches per day; and another for product B, scheduled for production line 2, with 8 batches of 100 units per batch and an estimated completion rate of 1.6 batches per day (this rate can be adjusted based on actual production conditions). Production work orders serve as the core instructions for production execution, guiding the orderly execution of subsequent production activities.

[0085] Step S2013: determining the number of pallets on the pallet position based on the photoelectric signal, and generating production line cache information based on the number of pallets.

[0086] Specifically, the number of pallets on the pallet position is determined based on the photoelectric signal: the MES subsystem analyzes and processes the collected photoelectric signals. By judging the state changes of the photoelectric signal of each pallet position, the number of pallets on the pallet position on the current production chain can be accurately determined. For example, after a period of data collection and analysis, the MES subsystem counts that there are 50 pallet positions on the production chain, of which 30 are occupied by pallets. Generate production line cache information based on the number of pallets: Based on the determined number of pallets, combined with the carrying capacity of each pallet and the status of the material on the current pallet (such as whether it is fully loaded, the type of material, etc.), the MES subsystem generates production line cache information. This information includes the current cache capacity of the production line, the occupied cache capacity, the remaining cache capacity, and the relevant information about the materials carried by each pallet. Assume that each pallet has a standard carrying capacity of 50 pieces. Currently, 20 of the 30 pallets are fully loaded with product A, each carrying 50 pieces, and 10 pallets are empty. Therefore, the production line's occupied buffer capacity is 20 × 50 = 1000 pieces, and the remaining buffer capacity is (30 - 20) × 50 = 500 pieces. This information allows production managers to intuitively understand the real-time status of the production line's buffer, providing an important basis for material scheduling and production arrangements.

[0087] Step S2014: determine the planned completion quantity based on the production work order in the preset time period, and extract the number of remaining pallets and the number of used pallets on the pallet position from the production line cache information.

[0088] Specifically, the types and quantities of products to be produced, known as the planned completion quantity, are determined based on daily production work orders. These products can include products from multiple suppliers. When the production line starts, the pallet slots are saturated, meaning each slot is occupied by pallets of material. After a period of production, the pallets corresponding to the used materials on the production lane are removed from the shelves. The remaining pallets represent the number of used pallets, while the remaining pallets represent the number of remaining pallets. The production line's first-level cache can be determined by the number of unused pallets on the production lane.

[0089] Furthermore, the planned completion quantity is determined based on the production work orders for a preset time period. Production work orders are generated based on the production plan for a preset time period, which clearly specifies the number of products to be produced for each production batch. The planned completion quantity can be determined by summing the production quantities of the corresponding products in the production work orders. For example, if a production work order for a product schedules 10 production batches, each with 50 units, the planned completion quantity for that product is 10 x 50 = 500 units.

[0090] Extract the remaining and used pallets on a pallet location from the production line cache: The production line cache details the usage of pallet locations along the production chain. By querying the production line cache database, you can obtain the remaining and used pallet numbers on the current pallet location. Assuming the production line cache shows that there are 80 pallet locations on the production chain, of which 50 are used, the remaining number of pallets is 80 - 50 = 30.

[0091] Step S2015: Based on the number of remaining pallets and the number of used pallets, the MES algorithm is used to calculate the remaining completion quantity and the completed quantity respectively; the MES algorithm is a calculation algorithm based on artificial intelligence.

[0092] Specifically, the raw materials required for each product are pre-set, and the correspondence between the products and the required raw materials is stored in the MES subsystem. Based on the correspondence, the number of remaining pallets and the number of used pallets, the MES algorithm is used to calculate the remaining completion quantity and the completed quantity respectively, that is, the remaining product categories and quantities that need to be produced and the product categories and quantities that have been produced.

[0093] Furthermore, an MES algorithm is used to calculate the remaining and completed quantities based on the number of remaining and used pallets, respectively. The MES algorithm employed here is based on artificial intelligence. It considers various factors, such as the typical material load per pallet, material loss during production, and production efficiency. For example, if each pallet carries an average of 10 items, and 50 pallets are used, assuming a 5% material loss rate, the completed quantity might be calculated as 50 × 10 × (1 - 5%) = 475 items. Regarding the remaining completed quantity, with 30 pallets remaining, using the same load capacity and loss rate, the remaining completed quantity might be 30 × 10 × (1 - 5%) = 285 items (the actual calculation will be refined based on more detailed parameters in the algorithm model).

[0094] In step S2016, the material calculation is performed using the MES algorithm based on the planned completion quantity, the completed quantity and the remaining completion quantity. When the sum of the completed quantity and the remaining completion quantity is less than the planned completion quantity and there are vacant pallet positions on the production chain, a material request needs to be initiated, and the material request information is submitted based on the material request; the material request information includes the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the required material number and the required material quantity.

[0095] In an optional implementation, the above step S2016 includes:

[0096] Step a1, material calculation basis:

[0097] During the production process, materials are calculated using MES algorithms. This involves three key data points: planned completion, completed, and remaining completion. Planned completion is the final quantity of a product, as determined by the production order or production plan; completed is the number of products already completed during the production process; and remaining completion is the difference between planned completion and completed, representing the number of products remaining to be completed.

[0098] Material calculations are performed using MES algorithms based on planned, completed, and remaining quantities. The MES algorithm comprehensively considers these quantities, along with the bill of materials (BOM) and production process requirements, to determine the types and quantities of materials required for the current production phase. For example, if the product's BOM indicates that the production of one item requires three items of material A and two items of material B, then the completed and remaining quantities can be combined to accurately calculate the required quantities of both materials.

[0099] Step a2, triggering conditions for material request:

[0100] When the sum of completed and remaining completed quantities is less than the planned completed quantity, this means that actual production progress is behind schedule, and there may be a material shortage. At the same time, if there are vacant pallets on the production chain, this indicates that the production line has the space to receive new materials. Only when these two conditions are met should a material request be initiated and submitted.

[0101] For example, a material request is required when the sum of the completed and remaining completed quantities is less than the planned completed quantity and there are available pallet slots on the production chain. For example, if the planned completed quantity is 600 pieces, the completed quantity is 475 pieces, and the remaining completed quantity is 285 pieces, the sum of these is 475 + 285 = 760 pieces, which is greater than the planned completed quantity. In this case, a material request is not required. However, if the planned completed quantity is 800 pieces, the completed quantity is 475 pieces, and the remaining completed quantity is 285 pieces, the sum of these is 475 + 285 = 760 pieces, which is less than the planned completed quantity. If there are available pallet slots on the production chain, a material request is required.

[0102] The call information is composed of the following:

[0103] Factory where the production line is located: Clarify the specific factory address and factory name to which the production line belongs. This will help to accurately locate the source factory of material demand in a group or multi-factory operation model.

[0104] Production Line Stock Location: Indicates the warehouse or inventory area where the production line stores materials so that materials can be retrieved from the correct inventory location.

[0105] Production line loading point: Indicates the specific loading location of the production line where the materials need to be transported to ensure that the materials can be accurately delivered to the production use point.

[0106] Production line name: Clearly identify the name of the production line that requires materials, making it easier for production management and material distribution personnel to quickly identify the corresponding production line.

[0107] Supplier: This means providing information on the supplier of the required materials, including the supplier's name, contact information, etc., to facilitate timely communication with the supplier regarding material supply matters.

[0108] Required material number: The unique number of the material. The material number can be used to accurately identify the specific type of material required to avoid material confusion.

[0109] Required material quantity: Based on the production progress and material consumption, calculate the specific quantity of materials that need to be replenished to ensure the accuracy of material supply, meet production needs and avoid excessive inventory backlogs.

[0110] When the triggering conditions for a material request are met, the relevant information will be organized and submitted in accordance with the above-mentioned material request information composition requirements to ensure the material supply of the production line and maintain normal production.

[0111] Step S2017: When the sum of the completed quantity and the remaining completed quantity is greater than or equal to the planned completed quantity, there is no need to initiate a material request.

[0112] Specifically, when the sum of the completed quantity and the remaining completed quantity is greater than or equal to the planned completed quantity, it indicates that the actual production progress has reached or exceeded the planned progress. At this time, the material supply can meet the production demand at the current stage, and there is no need to initiate a material request.

[0113] Step S202: receiving material request information and creating a pallet material handling task based on the material request information.

[0114] Specifically, the above step S202 includes:

[0115] Step S2021, based on the supplier and the required material number, determine the corresponding preset buffer area inventory location, the pallet number in the preset buffer area, and the material number corresponding to the pallet.

[0116] In an optional implementation, the above step S2021 includes:

[0117] Step b1, Determine the Preset Buffer Area Inventory Location: Companies typically establish a database that maps material supply and storage. This database pre-configures a corresponding pre-set buffer area inventory location for each type of material supplied by each supplier. Once the supplier and the required material number are determined, the database can be queried to quickly retrieve the corresponding pre-set buffer area inventory location for that material based on a combined index of the supplier name and material number. For example, supplier A, which regularly supplies parts with material number M001 to the production line, has its corresponding pre-configured buffer area inventory location pre-configured in the database as shelf A in warehouse area 3.

[0118] Step b2, determine the pallet number in the preset cache area and the material number corresponding to the pallet: within the preset cache area, materials are stored and circulated in units of pallets. Also with the help of the database, after obtaining the inventory location of the preset cache area, further query the pallet information related to the required material number under the inventory location. The database records the material number and pallet number carried by each pallet. For example, in the preset cache area corresponding to shelf A in area 3 of the above-mentioned warehouse, it can be found through query that the pallet with pallet number T005 carries material with material number M001, which determines the pallet number in the preset cache area and the material number corresponding to the pallet. In this way, after the material request is initiated, the storage location of the material in the preset cache area can be accurately located, the allocation and supply of materials can be accelerated, and the efficient operation of the production line can be guaranteed.

[0119] Step S2022: Create a pallet material handling task based on the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the preset buffer area inventory location, the pallet number in the preset buffer area, the material number corresponding to the pallet, and the required material quantity.

[0120] In some optional implementations, the above step S2022 includes:

[0121] Create a pallet material handling task, that is, plan the handling task, including:

[0122] Step c1: Determine the starting point of the transport: Determine the starting location of the pallet material based on the preset buffer storage location. For example, if the preset buffer storage location is shelf A in area 3 of the warehouse, then the transport starting point is that shelf.

[0123] In step c2, the transport destination is determined based on the production line's factory location, production line inventory location, and production line loading point. Assuming the production line is located in Factory X, the production line inventory location is the temporary material storage area in Workshop 1, and the production line loading point is the loading platform near workstation 3 of production line 1, the transport destination is the loading platform.

[0124] Create pallet material handling tasks based on the production line's factory location, production line inventory location, production line loading point, production line name, supplier, preset buffer area inventory location, pallet number in the preset buffer area, material number corresponding to the pallet, required material quantity, handling start point, and handling end point.

[0125] Step S203: Sending a handling instruction to the automatic handling equipment based on the pallet material handling task. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0126] Step S204: Based on the transport instruction, the automatic transport equipment is controlled to remove the required pallet materials from the preset buffer area, and based on the removed pallet materials, the automatic transport equipment is controlled to directly connect with the production line to complete the material replenishment and handover. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0127] The production line material supply and replenishment method provided in this embodiment generates a production work order based on a production plan for a preset time period, determines the number of pallets on a pallet slot based on a photoelectric signal, and generates production line cache information based on the pallet number. This method accurately obtains the production work order and the production line's first-level cache information, paving the way for subsequent material request initiation. The MES algorithm utilizes a combination of the production line's available pallet slots and the line's planned completion quantity, completed quantity, and remaining completion quantity to determine whether the production line needs to request material. This accurately determines the production line's need for replenishment based on the completion quantity and available pallet slots, and avoids situations where there are no pallet slots available for replenishment, ensuring the normal operation of the production line replenishment process. The corresponding preset cache storage location, pallet number in the preset cache, and material number corresponding to the pallet are determined based on the supplier and the required material number. This facilitates the precise identification of the supplier and material number of the material required by the production line's required material in the preset cache, the pallet number, and the material number corresponding to the pallet. Furthermore, pallet material handling tasks are accurately created based on the production line's factory location, production line storage location, production line loading point, production line name, supplier, preset cache storage location, pallet number in the preset cache, material number corresponding to the pallet, and required material quantity.

[0128] In this embodiment, a production line material supply and replenishment method is provided, which can be used in the above-mentioned computer equipment. A production line material supply and replenishment system is set in the computer equipment, such as Figure 4As shown in the figure, the production line feeding and replenishment system includes the MES subsystem (Manufacturing Execution System, production management subsystem), EWM subsystem (Extended Warehouse Management, warehouse management subsystem), WCS subsystem (Warehouse Control System, warehouse control subsystem) and RCS subsystem (Robotic Control System, equipment scheduling subsystem), which communicate in sequence. Figure 3 FIG. 1 is a flow chart of a production line material supply and replenishment method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0129] Step S301: Obtain the production line cache information and the production work order of the preset time period, and use the MES algorithm to determine whether to initiate a material request based on the production line cache information and the production work order of the preset time period. When a material request is required, submit the material request information. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0130] Step S302: Receive material request information and create a pallet material handling task based on the request information. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0131] Step S303: issuing a transport instruction to the automatic transport equipment based on the pallet material transport task.

[0132] Specifically, if Figure 4 and Figure 5 As shown, the pallet material handling task is based on the pallet material handling task to issue a handling instruction to the automatic handling equipment, that is, the pallet material handling task allocation process, step S303 includes the following steps:

[0133] Step S3031, Instruction Reception and Interpretation: The WCS subsystem receives the pallet material handling task sent by the EWM subsystem and interprets it. It identifies the specific tasks that the automated handling equipment needs to perform, such as where to move the pallets, where to move them, and the quantity to be moved.

[0134] Step S3032: Equipment Scheduling and Path Planning: The WCS subsystem schedules equipment based on the real-time status of automated handling equipment (e.g., equipment location, availability, etc.). For example, it selects the idle automated guided vehicle (AGV) closest to the starting point to perform the handling task. The WCS subsystem also uses its own path planning algorithm to plan the optimal path for the automated handling equipment, taking into account factors such as the warehouse aisle layout, other equipment, and personnel activity, to avoid collisions and congestion.

[0135] Step S3033: Collaboration with the RCS Subsystem: The WCS subsystem assigns the handling task to the selected automated handling equipment (i.e., sends handling instructions to the AGV) and collaborates with the RCS subsystem (Robot Control System, if the automated handling equipment is a robot). It sends the RCS subsystem equipment operating parameters and task instructions, such as the robot's operating speed and motion sequence, to ensure that the automated handling equipment can accurately execute the handling task.

[0136] For example, first designate handling personnel or equipment: Allocate handling resources appropriately based on the production line name and task urgency. If the material handling task is urgent and Line 1 is critical, assign an experienced forklift driver or automated handling equipment to handle the handling. For example, assign forklift driver Zhang San to carry out this pallet material handling task. When deciding to use automated handling equipment, ensure that the equipment is operating normally and that its task queue is conflict-free. Then, associate supplier information: Record the material supplier's information so that you can communicate with the supplier promptly if any issues arise during the handling process. If the supplier is Company A, clearly mark this in the handling task record to facilitate tracing the material source and related responsibilities.

[0137] Step S304 , based on the transport instruction, the automatic transport device is controlled to remove the required pallet materials from the preset buffer area, and based on the removed pallet materials, the automatic transport device is controlled to directly connect with the production line to complete the material replenishment and handover.

[0138] Specifically, the above step S304 includes:

[0139] Step S3041, based on the handling instructions, supplier, inventory location of the preset buffer area, pallet number in the preset buffer area, material number corresponding to the pallet and required material quantity, the automatic handling equipment is controlled to adopt the first-in-first-out principle and / or the first-out-expired principle to remove the corresponding pallet material from the designated preset buffer area.

[0140] In an optional implementation, the above step S3041 includes:

[0141] Determination and implementation of material removal principles:

[0142] First-in, First-out (FIFO) principle: The RCS subsystem controls the automated handling equipment, based on handling instructions and the inventory location information in the pre-set buffer area, to query the database for each pallet's entry date. For pallets from a specific supplier whose corresponding material numbers meet the requirements, the pallet with the earliest entry date is prioritized for removal from the shelf. For example, in the pre-set buffer area of ​​shelf A in warehouse area 3, there are three pallets (T005, T006, and T007), all carrying material number M001, which entered the warehouse three, five, and two days ago, respectively. Following the FIFO principle, the RCS subsystem controls the automated handling equipment, which will first select pallet T006 for removal.

[0143] First Expired, First Out (FEFO) principle: If a material has expiration dates, the RCS subsystem controls the automated handling equipment to query the database for the expiration date of each pallet. For pallets that meet the supplier and material number requirements in the handling order, the pallet with the earliest expiration date is prioritized for removal. For example, in the same buffer zone, pallet T005 has an expiration date of 5 days, pallet T006 has an expiration date of 3 days, and pallet T007 has an expiration date of 7 days. Based on the first expired, first out principle, the RCS subsystem controls the automated handling equipment to select pallet T006 for removal.

[0144] Mixed principle (if both are selected): If the company stipulates that both the first-in, first-out principle and the first-out, first-out principle should be followed, the RCS subsystem controls the automatic handling equipment to first select the set of pallets with the earliest expiration time, and then select the pallet with the earliest entry time from this set for destocking.

[0145] Step S3042: Based on the pallet materials removed from the shelves, the automatic handling equipment is controlled to carry the pallet materials to the queue position.

[0146] Specifically, the RCS subsystem controls the automated handling equipment to successfully remove pallets that meet the requirements. It then moves the pallets to the designated queue according to the path planning information in the handling instructions (planned by the WCS subsystem). The queue is typically an area near the production line used to temporarily store materials awaiting replenishment. During the handling process, the RCS subsystem controls the automated handling equipment to maintain continuous communication with the WCS subsystem, reporting its position and operating status in real time to ensure safe and accurate handling. For example, an automated guided vehicle (AGV) smoothly transports the pallet to the queue along the planned path and sends an arrival confirmation signal to the WCS subsystem upon arrival.

[0147] Step S3043: Control the automatic handling equipment on the queue to directly connect with the production line to complete material replenishment and handover.

[0148] In some optional implementations, step S3043 includes:

[0149] Step d1, controlling the automatic handling equipment at the queue position to apply for material loading request to the production line.

[0150] Step d2: When there is an empty pallet position on the production line, the loading request is determined to be approved, and the automatic handling equipment is controlled to transport the pallet material to the loading point of the production line to complete the material replenishment and handover.

[0151] Specifically, the RCS subsystem controls the automatic handling equipment on the queue to apply for a loading request from the production line. When the automatic handling equipment on the queue receives a replenishment request signal from the production line (for example, the production line detects a material shortage), the automatic handling equipment, according to the docking instruction, transports the pallet material to the designated loading point of the production line to complete the material replenishment handover. During the handover process, the automatic handling equipment precisely cooperates with the docking mechanism of the production line to ensure that the pallet material can be accurately received by the production line. For example, the automatic handling equipment accurately positions the pallet on the loading platform of the production line, and smoothly transfers the material to the production line through a robotic arm or other docking device. At the same time, it feeds back information on the completion of the material replenishment handover to the MES subsystem so that the MES subsystem can update the production progress and material inventory status.

[0152] Step S305: After the material replenishment handover is completed, the task handover results are fed back step by step; the preset buffer area inventory information is updated based on the task handover results, and posting information is generated based on the inventory information; the inventory information includes the inventory information of the preset buffer area warehouse transferred to the production line loading point warehouse at regular intervals; and the material voucher is generated based on the posting information.

[0153] Specifically, the production line's material supply and replenishment system also includes an SAP subsystem, which plays an important role in providing data in the foundational stages of material calculations. It stores the company's complete material master data, including basic material attributes, units, procurement information, and cost information. When performing material calculations, the MES subsystem obtains data such as the standard material usage and cost from the SAP subsystem. This data is the basis for accurately calculating the material quantity and cost required for the planned completion quantity. For example, if material A is required to produce a certain product, the MES subsystem obtains the standard usage of material A from the SAP subsystem as 5 units per product. Based on the planned completion quantity of 100 pieces, it can be calculated that the planned usage of material A required to produce the product is 500 units.

[0154] The above step S305 includes:

[0155] Step S3051: Feedback the task handover results step by step:

[0156] After completing the material replenishment handover, the automatic handling equipment first feedbacks the handover success information to the WCS subsystem, along with the handover time, detailed information about the handed-over material (such as pallet number, material number, quantity, etc.), and the equipment's own operating status data during the handover process.

[0157] After receiving the feedback, the WCS subsystem organizes and performs preliminary analysis on the data. It then forwards the handover results to the EWM subsystem. It also reports on equipment scheduling and route execution throughout the entire handling and handover process, including any route changes, any temporary equipment failures, and how they were handled. The handover results are then forwarded to the MES subsystem via the EWM subsystem.

[0158] The MES subsystem receives feedback from the EWM subsystem, records the task handover results in the production task management module, updates the production progress information, and sends a notification to the relevant production management personnel to inform them that the material replenishment handover has been completed.

[0159] Step S3052: Update the preset cache area inventory information:

[0160] After receiving notification from the WCS subsystem regarding the completion of a material replenishment handover, the EWM subsystem updates the inventory information in the pre-set buffer based on the material information in the handover result (such as the pallet number and corresponding material quantity). For example, if five pallets of material M001 are moved from the pre-set buffer on shelf A in warehouse area 3 to the production line, the EWM subsystem will reduce the inventory quantity of material M001 in that buffer accordingly, update the pallet occupancy status, and mark the moved pallets as "outbound."

[0161] At the same time, the EWM subsystem, according to scheduled execution rules, updates inventory information transferred from the pre-set buffer area to the production line loading point. Assuming an hourly update, the EWM subsystem counts the material types, quantities, and corresponding time periods transferred from the pre-set buffer area to the production line loading point during each update, generating detailed inventory transfer records. The EWM subsystem is integrated with the SAP subsystem, synchronizing the updated pre-set buffer area inventory information with the SAP subsystem in real time to ensure inventory data consistency.

[0162] This embodiment provides a production line replenishment method that updates inventory status in real time. The EWM subsystem, based on task completion information from the WCS subsystem, instantly confirms that materials have been moved from the pre-set buffer area to the production line and completed handover, thereby rapidly updating inventory data. Regular data transmission back to the SAP subsystem ensures overall data consistency: Inventory update data is transmitted back to the SAP subsystem daily, ensuring that inventory data across the entire enterprise supply chain management system remains synchronized.

[0163] Step S3053: Generate Posting Information: Based on the updated inventory information in the preset buffer, the EWM subsystem generates posting information. This posting information includes the material entry / exit type (e.g., this time, the material is being removed for production line replenishment), the material value (calculated based on the material cost and quantity), the change in inventory location (from the preset buffer to the production line), and the corresponding financial account. For example, if material M001, valued at 1,000 yuan, is transferred from the preset buffer on shelf A in warehouse area 3 to the loading point of production line 1, the EWM subsystem generates a corresponding posting record, recording the material's departure amount, the change in inventory location, and the corresponding production cost account. The EWM subsystem then sends the posting information to the SAP subsystem.

[0164] Step S3054, as Figure 5 As shown, the SAP subsystem automatically generates a material voucher based on the generated posting information. A material voucher serves as the official financial and business record of material inbound and outbound transactions and inventory changes. It contains detailed material information (material number, name, specifications, etc.), quantity, value, inbound and outbound date, inventory location changes, and related business document numbers (such as transfer order number and production order number). These material vouchers can be used for financial accounting, inventory audits, and subsequent business traceability. For example, a material outbound voucher numbered 20250312-001 records the outbound shipment of material M001 from the pre-set buffer area on shelf A in warehouse area 3 on March 12, 2025. The quantity consists of five pallets (each carrying a certain amount of material) and the value is 100 yuan. The corresponding transfer order number is BT-20250312-01 and the production order number is PO-202503-001.

[0165] The production line material supply and replenishment method provided in this embodiment controls the automatic handling equipment based on the handling instructions, supplier, inventory location of the preset buffer area, pallet number in the preset buffer area, material number corresponding to the pallet, and required material quantity to remove the corresponding pallet material from the designated preset buffer area using the first-in, first-out principle and / or the first-expired, first-out principle. This ensures the first-in, first-out principle of pallet materials and improves the availability of materials. The automatic handling equipment on the control queue is directly connected to the production line to complete the material replenishment handover without the need for step-by-step feedback, thereby improving replenishment efficiency, providing conditions for normal replenishment of the production line, and ensuring the continuity of production line output. By feeding back the task handover results step by step, unnecessary communication costs are reduced, replenishment information is shared at all levels, and work efficiency is improved. The inventory information of the preset buffer area is updated based on the task handover results, and posting information is generated based on the inventory information, realizing real-time updating of inventory information and ensuring the consistency between accounts and actuals. Material vouchers are generated based on posting information to ensure the consistency between accounts.

[0166] As one or more specific application embodiments of the present invention, combined with Figures 4 to 6 The present invention provides a production line feeding and replenishment method that is further described in detail as follows:

[0167] like Figure 4 and Figure 5 As shown in the figure, a production line material replenishment system is used to implement the production line material replenishment method. The production line material replenishment system includes the MES subsystem (Manufacturing Execution System, production management subsystem), EWM subsystem (Extended Warehouse Management, warehouse management subsystem), WCS subsystem (Warehouse Control System, warehouse control subsystem) and RCS subsystem (Robotic Control System, equipment scheduling subsystem), which communicate in sequence. The process of combining the MES subsystem, EWM subsystem, WCS subsystem and RCS subsystem to carry out production line material replenishment is as follows Figure 6 The steps are shown in Table 1 below:

[0168] Table 1 Production line feeding and replenishment process

[0169]

[0170] The production line material supply and replenishment method provided in this embodiment realizes efficient task execution. The EWM subsystem quickly creates a destocking task based on the material request of the MES subsystem and sends it to the WCS subsystem. The WCS subsystem can quickly dispatch the AGV to perform the handling task. This efficient task transfer and execution mechanism reduces the waiting time for materials. For example, on an electronic product production line, when the MES subsystem detects that a key component is insufficient in inventory and issues a material request, the EWM subsystem quickly responds by creating a destocking task, and the WCS subsystem dispatches the AGV to quickly transport the pallet carrying the component to the production line interface. The entire process may only take a few minutes, which greatly shortens the material supply cycle compared to manual processing and improves the overall production efficiency of the production line.

[0171] Reduced manual intervention: The entire process, from material ordering to inventory updating, is largely automated, reducing manual operations. Manual operations are prone to human errors, such as incorrectly removing materials from shelves or incorrectly transporting materials. Automated processes, through accurate command transmission between systems and precise execution by equipment, reduce the likelihood of these errors, making the production process smoother and more efficient.

[0172] Data Accuracy: The data exchange and feedback mechanisms between subsystems ensure data accuracy. The WCS subsystem reports task completion status to the EWM subsystem, which then confirms the task and updates inventory based on this information. This data undergoes multiple verifications during this process. For example, information such as pallet number, material type, and quantity reported by the WCS subsystem is compared with the data generated when the EWM subsystem created the task. Inventory updates are only performed after ensuring accuracy, reducing the possibility of data errors.

[0173] Enhanced material traceability: From the material request in the MES subsystem, to the task creation in the EWM subsystem, the AGV transportation scheduling in the WCS subsystem, and finally the inventory update and transmission back to the SAP subsystem, data from the entire process is fully recorded and traceable. When product quality issues or material supply anomalies arise, the source of the problem can be quickly traced back through the interconnected data between systems. For example, if a quality issue is discovered in a batch of products during production, detailed information such as the material's arrival time, storage location, and transportation process can be traced back through inventory data in the SAP subsystem, facilitating rapid resolution.

[0174] Optimizing internal enterprise processes: The collaborative work of the EWM, MES, WCS, and SAP subsystems optimizes the entire enterprise process, from production planning to material supply and inventory management. Seamless integration and information sharing between these systems enable better coordination among various departments. For example, the production department uses the MES subsystem to keep abreast of material supply status, the logistics department efficiently executes material handling tasks through the EWM subsystem and WCS, and the finance department uses the SAP subsystem to obtain accurate inventory data for cost accounting. These collaborative efforts improve overall operational efficiency.

[0175] Facilitates enterprise decision-making: Accurate and timely inventory data and relevant production process data are transmitted back to the SAP subsystem. Management can use this data to formulate more reasonable production plans, procurement plans, and resource allocation plans.

[0176] This embodiment also provides a production line supply and replenishment system for implementing the aforementioned embodiments and preferred implementations. Details already described will not be repeated. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. While the systems described in the following embodiments are preferably implemented using software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0177] This embodiment provides a production line supply and replenishment system, such as Figure 7 Shown, including:

[0178] MES subsystem 701 is used to obtain production line cache information and production work orders in a preset time period, and use MES algorithm to determine whether to initiate a material request based on the production line cache information and the production work orders in the preset time period, and submit the material request information when a material request needs to be initiated.

[0179] The EWM subsystem 702 is in communication with the MES subsystem. The EWM subsystem is used to receive the material request information transmitted by the MES subsystem and create a pallet material handling task based on the material request information.

[0180] The WCS subsystem 703 is in communication with the EWM subsystem. The WCS subsystem is used to issue handling instructions to the automatic handling equipment based on the pallet material handling task.

[0181] The RCS subsystem 704 is in communication with the WCS subsystem. The RCS subsystem includes automatic handling equipment. The RCS subsystem is used to control the automatic handling equipment to remove the required pallet materials from the specified preset buffer area based on the handling instructions, and to control the automatic handling equipment to directly connect with the production line to complete material replenishment and handover based on the removed pallet materials.

[0182] In some optional implementations, the MES subsystem 701 includes:

[0183] The production plan and photoelectric signal acquisition module is used to obtain the production plan for a preset time period and collect the photoelectric signals transmitted by each pallet position on the production chain.

[0184] The production work order generation module is used to generate production work orders based on the production plan of the preset time period.

[0185] The production line cache information generation module is used to determine the number of pallets on the pallet position based on the photoelectric signal and generate production line cache information based on the number of pallets.

[0186] The pallet quantity calculation module is used to determine the planned completion quantity based on the production work order in a preset time period, and to extract the remaining number of pallets and the number of used pallets on the pallet position from the production line cache information.

[0187] The module for calculating the remaining completion quantity and the completed quantity is used to calculate the remaining completion quantity and the completed quantity respectively based on the remaining number of pallets and the number of used pallets using the MES algorithm; the MES algorithm is a calculation algorithm based on artificial intelligence.

[0188] The material request judgment module is used to calculate materials based on the planned completion quantity, completed quantity and remaining completion quantity using the MES algorithm. When the sum of the completed quantity and the remaining completion quantity is less than the planned completion quantity and there are vacant pallet positions on the production chain, a material request needs to be initiated and the material request information is submitted based on the material request; the material request information includes the factory where the production line is located, the production line inventory location, the production line loading point, the production line name, the supplier, the required material number and the required material quantity; when the sum of the completed quantity and the remaining completion quantity is greater than or equal to the planned completion quantity, there is no need to initiate a material request.
