Description

[0001] The application number of the original application is: 202410209250X, the application date is: February 26, 2024, and the name of the invention is: A production line and intelligent scheduling, process path planning and scheduling method and system. Technical Field

[0002] The present invention relates to the technical field of automated material handling and transportation, and in particular to a production line and intelligent scheduling, process path planning method and system. Background Art

[0003] In intelligent industrial production, overhead conveyor systems present several technical challenges, particularly regarding the movement of the conveyor mechanism. These systems typically utilize an electric chain drive, limiting the movement of items along a fixed track to a single direction. While this design facilitates continuous production processes in some respects, it presents several key inconveniences in the face of intelligent manufacturing demands.

[0004] First, intelligent manufacturing requires a high degree of flexibility and adaptability, but the limitations of fixed tracks and one-way movement make it difficult for the system to quickly adjust to changing production needs. Intelligent industrial production needs to be able to quickly respond to market changes and the diversity of production needs, but the single-directional movement and fixed track design greatly reduce this flexibility.

[0005] Secondly, fixed-speed movement is inconsistent with the variable speed and dynamic adjustment requirements of intelligent manufacturing. In intelligent production, different stages and workstations may require different processing speeds, and fixed-speed conveyor systems cannot meet this demand, potentially leading to inefficiencies and production delays.

[0006] Furthermore, this system also impacts the scheduling of items across multiple lines. Intelligent industrial production requires systems that can quickly adjust and reorganize to optimize production processes. However, the one-way and enclosed track design makes cross-line scheduling inefficient, limiting overall production flexibility and responsiveness.

[0007] In short, intelligent industrial production places high demands on the flexibility, adaptability and dynamic adjustment capabilities of system scheduling. Traditional suspended conveyor line systems have obvious limitations in these aspects and require further technological innovation and improvement to adapt to the development trend of intelligence.

[0008] Due to the above-mentioned technical problems of the existing suspended assembly line system, it is difficult to fully understand the production process, which affects the effect of intelligent scheduling. It also has deficiencies in data processing speed and real-time response capabilities. The degree of automation and flexibility may not be sufficient to support complex intelligent scheduling and rapidly changing process paths, especially when dealing with personalized and small-batch orders.

If it is, the estimated completion time of the latest completed work section task in the ongoing state is used, where estimated completion time = start time + production cycle time.

Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances. Multiple technical solutions in the same embodiment, as well as multiple technical solutions in different embodiments, can be permuted and combined to form new technical solutions that do not conflict or contradict each other, and all of these solutions are within the scope of protection claimed by the present invention.

[0054] Combine Figure 1 This embodiment proposes an assembly line, including: an assembly line trough body, a slide 2, a bearing surface 4, a power supply and a conductive belt 6, the slide 2 is located in the assembly line trough body, the assembly line trough body is provided with a bearing surface 4, the conductive belt 6 is provided in the assembly line trough body, an insulating layer 5 is provided between the conductive belt 6 and the assembly line trough body, a number of workstations are distributed in the assembly line trough body, equipment is provided on the workstations, the assembly line trough body is provided with an inlet and an outlet extending to the equipment, the inlet and outlet of the assembly line trough body and the workstations are provided with electronic tag readers, the equipment and the electronic tag reader are both connected to the main control end, and the power supply is connected to both the conductive belt 6 and the electronic tag reader.

[0055] Electronic tags can be RFID tags, NFC tags, barcode tags, QR code tags, Bluetooth tags, UHF tags, and LF / HF tags. The corresponding electronic tag readers are: RFID reader, NFC reader, barcode scanner, Bluetooth reader, UHF reader, and LF / HF reader.

[0056] The power supply is used to power the conductive belt 6 and the electronic tag reader. Through the above-mentioned modular assembly line trough, the corresponding assembly line can be matched according to the production and processing needs of different items, which can meet the cross-line operation and cooperate with the self-driven hanging tool. It is beneficial to improve the efficiency of the production link and has great production line adaptability.

[0057] An assembly line adopting the technical solution of this embodiment, wherein the assembly line trough is the basic structure of the assembly line, which is in the shape of a long strip and can be straight, curved or have a specific shape to adapt to a specific path; it provides a moving path for the hanging tool. An electronic tag that matches the electronic tag reader is set on the hanging tool, and the electronic tag information includes the hanging tool code, information about the items carried by the hanging tool, the processing status of the items, the item code, etc. The electronic tag information is read by the electronic tag reader to locate the position of the hanging tool carrying the corresponding items on the assembly line. The slide 2 inside the assembly line trough is used to guide the hanging tool to move smoothly along the assembly line trough, the bearing surface 4 is used to bear the weight of the hanging tool, and the guide groove plays a guiding role to ensure the stable operation of the hanging tool and prevent it from offsetting or derailing during movement. The conductive belt 6 contacts the hanging tool, providing electrical energy for its self-drive. The hanging tool can adjust its own speed and direction of movement on the assembly line. When the items loaded by the hanging tool need to be dispatched from one production line to another, the adjustable speed and direction of the hanging tool can achieve cross-line operation at the shortest distance and fastest speed, thereby improving the efficiency of the corresponding production link. In addition, the assembly line trough can be adjusted according to the needs of the production line, which has strong adaptability. This changes the existing situation of relying on the assembly line to change the movement state of the hanging tool. The assembly line structure is modified to provide electrical energy to the self-driven hanging tool, allowing the hanging tool to change its own movement state according to the production and processing requirements of the loaded items, and no longer being restricted by the assembly line structure. In the self-driven hanging tool of this embodiment, it can be imagined that the driving part of the hanging component is located in the slide 2 and moves along the guide groove. The part of the hanging tool that loads the object is located below the assembly line groove body. The conductive belt 6 is in direct contact with the driving part to provide the driving part with the electric energy required for movement, or directly charges it, thereby realizing the autonomous movement of the driving part in the guide groove without interruption of power supply.

[0058] The assembly line trough is the core component of the main assembly line in a suspended assembly line system. It is typically made of high-strength, corrosion-resistant materials such as carbon steel, stainless steel, or aluminum alloy. These materials ensure the trough's strength and durability, enabling it to withstand long-term heavy loads and the various challenges of industrial environments.

[0059] The cross-section of a pipeline trough is typically rectangular or has a special geometric shape, designed to accommodate different mounting requirements and space constraints. Its dimensions vary depending on load capacity and application scenarios to accommodate different industrial applications and space layouts.

[0060] The interior of the flow line body is designed to support and guide the mounted parts or hanging tools (such as hanging tools, pulleys or slides). This usually includes one or more smooth internal flow lines to reduce sliding friction and ensure smooth operation of the mounted parts.

[0061] The ends of the assembly line trough are usually designed with interfaces for connecting with other assembly line parts, or cooperating with other structures such as corners and branches. These interfaces are precisely docked to maintain the continuity and stability of the entire assembly line.

[0062] In areas subject to greater loads, the conveyor belt may have additional reinforcements, such as thickened walls or reinforcing ribs, to provide additional support and stability.

[0063] In addition, the design of the assembly line trough must take into account strength, durability, precision and applicability. For example, special surface treatments such as galvanizing, spraying or anodizing will not only improve the durability of the assembly line trough, but also help reduce maintenance requirements; the design of easy-to-clean surfaces ensures the efficient and reliable operation of the hanging assembly line system.

[0064] The bearing surface 4 directly bears the weight of the mounted items. This part needs to be specially strengthened to withstand long-term repeated loads. Reinforced metal materials can be used for thickening or adding reinforcement ribs.

[0065] The chute 2 is a cavity within the assembly line trough, used to guide and support the mounted components or hanging tools, such as hanging tools, pulleys, or sliders, that move along the trough, ensuring smooth operation. The chute 2 can be square, concave, or convex to suit the design of the hanging tool. Its surface is smooth to reduce friction. Wear-resistant materials, such as hardened steel or special alloys, are used to withstand the wear and tear of long-term use.

[0066] The guide groove can be a hollow long gap or an embedded or raised edge, which cooperates with the corresponding part of the hanging tool, such as the connecting rod of the hanging tool. It is a long gap so that the connecting rod can pass smoothly through it, allowing the hanging tool to run along the predetermined track to prevent derailment.

[0067] In one embodiment, the slideway 2, bearing surface 4, and guide groove inside the assembly line trough are integrally formed, corresponding to different functional areas, and only need to meet common and different design requirements. For example, the bearing surface 4 needs to have characteristics such as smooth surface and low friction, strong pressure bearing capacity and wear resistance.

[0068] The conductive strip 6 is connected to the power supply and can be made of known conductive materials such as aluminum and copper. The insulating layer 5 is made of known insulating materials such as rubber. In one embodiment, the conductive strip 6 is a protruding strip, and the insulating layer 5 encases the conductive strip 6, leaving only the portion that directly contacts the power supply terminals of the hanging tool drive unit exposed. The conductive strip 6 of this embodiment provides reliable electrical conductivity, eliminating the need for additional electrical and control wiring within the assembly line trough, facilitating maintenance and inspection.

[0069] When multiple assembly line troughs are combined, they are fixedly connected at the interfaces of the assembly line troughs by welding, screws, bolts, etc., so as to ensure the stability of the overall structure.

[0070] Optionally, the pipeline tank body is in a straight line shape, a curved line shape, an inlet and outlet shape, a Y shape, a cross shape, or a combination thereof, such as Figure 4-10 The curved line trough and the straight line trough intersect, and an electronic tag reader is provided on the straight line trough at a predetermined distance from the intersection.

[0071] The different shapes of the pipeline trough body make the pipeline structure segmented and modular, which is convenient for assembly and disassembly, so that it can flexibly adapt to the needs of different production lines and has strong adaptability. The straight-line pipeline trough body 11 is provided with a straight-line guide groove 31, such as Figure 2 As shown; in order to avoid contradictions in the accompanying drawings, it should be noted that Figure 1 The pipeline trough body 1 marked in the middle is also in a straight line shape, and the corresponding guide groove 3 is also in a straight line shape.

[0072] As one of the implementation methods of this embodiment, the assembly line trough body is provided with a guide groove, and a conductive belt 6 is provided on the bearing surface 4 on both sides of the guide groove, and an insulating layer 5 is provided between the conductive belt 6 and the bearing surface 4; Figure 1-4 ,as well as Figure 7-10 As shown. The bearing surface 4, while simultaneously weighing the hanging tool, directly contacts the conductive strip 6, ensuring reliable electrical conductivity. Furthermore, placing the conductive strip 6 on the bearing surface 4 occupies minimal space, reduces the contact area between the hanging tool and the assembly line, and reduces energy loss caused by friction. Depending on the design of the hanging tool's power supply terminals, the conductive strip 6 may be present on only one side of the guide slot, or on both sides, all within the scope of this embodiment.

[0073] In an optional embodiment, the conductive belt 6 is disposed on the inner side of the assembly line trough body opposite the guide trough. When the hanging tool contacts the conductive belt 6 in the guide trough, the power supply terminals on the conductive belt 6 can directly connect to the conductive belt 6 to supply power or charge the hanging tool, thereby meeting its own power needs.

[0074] As one of the implementation methods of this embodiment, when the pipeline trough body is in a curved line shape, the guide groove, the slideway 2 and the bearing surface 4 are all in a curved line shape, such as Figure 5 and 6 As shown. The adaptable hanging tool moves along the corresponding curved line path in the curved line trough 12. Figure 5 and 6 In the figure, the conductive tape 6 and the insulating layer 5 matched therewith are not shown in order to simplify the wiring of the conductive tape 6.

[0075] In an optional embodiment, when the assembly line trough body is in the shape of an inlet and outlet, the assembly line trough body 15 in the shape of an inlet and outlet is provided with a curved guide groove 32 and a straight guide groove 31, the curved guide groove 32 and the straight guide groove 31 intersect, and an inlet 151 or an outlet 152 is provided on the side of the assembly line trough body in the bending direction of the curved guide groove 32. In a specific production environment, a hanging tool assembly warehouse, an item collection warehouse, or a processing station for hanging tools to load items is generally provided below the inlet and outlet. Through the inlet and outlet and the curved guide groove 32, the hanging tool can enter the slide 2 of the assembly line trough body of the assembly line and move along the straight guide groove 31 according to the set path. It can also exit from the slide 2 along the curved guide groove 32 through the inlet and outlet so that the items can be subjected to corresponding production and processing operations.

[0076] In an optional embodiment, when the assembly line trough body is in a Y shape, the Y-shaped assembly line trough body 13 includes a curved assembly line trough body 12 and a straight assembly line trough body 11, and the interface of the curved assembly line trough body 12 is connected to the side of the straight assembly line trough body 11, such as Figure 7 and 8 shown.

[0077] This design can meet the needs of hanging tools, such as hanging tools, sliders, etc., to turn from a straight-line assembly line trough 11 to another assembly line trough in the assembly line. The corresponding hanging items pass from the straight-line guide groove 31 through the connection between the two and enter the curved guide groove 32 to complete the above-mentioned turning process.

[0078] As one of the implementation methods of this embodiment, when the assembly line trough body is in a cross shape, the cross-shaped assembly line trough body 14 includes a curved line shaped assembly line trough body 12 and a straight line shaped assembly line trough body 11, and the two straight line shaped assembly line trough bodies 11 are connected and distributed in a cross shape, and the curved line shaped assembly line trough body 12 is located at the angle presented by the adjacent straight line shaped assembly line trough bodies 11 distributed in a cross shape, and the interfaces at both ends of the curved line shaped assembly line trough body 12 are respectively connected to the side of the straight line shaped assembly line trough body 11, as shown Figure 9 and10 As shown. On the one hand, it can meet the demand for the straight-line movement of the hanging tool on the assembly line. On the other hand, when it needs to be transformed into the slideway 2 of another assembly line trough, the turning process is completed by the curved assembly line trough 12 arranged at the angle of the cross shape. The four angles of the specific cross shape can be selectively provided with curved assembly line troughs 12. For example, four, three, two or one curved assembly line troughs 12 can be selected, depending on the specific production line processing requirements. In specific applications, the above-mentioned assembly line troughs of different shapes can be combined and are not limited to the examples listed in this embodiment.

[0079] As one implementation of this embodiment, a curved guide groove 32 intersects a straight guide groove 31. An electronic tag reader (not shown in the accompanying drawings) is installed on the straight assembly line trough 11 at a predetermined distance from the intersection. To optimize the wiring scheme, the electronic tag reader is installed on the straight assembly line trough 11. Conductive strips 6444, wrapped in an insulating layer 5, extend to the electronic tag reader installation location and are connected to the electronic tag reader's power cord. The electronic tag reader reads the code or identification code of the electronically tagged hanging tools passing through its location. The electronic tag reader transmits this signal to an external master control server, host computer, industrial computer, etc. via a wireless module. Electronic tags can be selected from RFID tags, NFC tags, barcode tags, etc. By reading the codes of these electronic tags with an electronic tag reader installed on the assembly line, the location of the hanging tools can be accurately located and tracked. Electronic tags can be installed on the inner wheel, tire, intermediate rod, etc., facilitating intelligent control and management of the entire suspension system.

[0080] There are usually workstations under the entrance and exit of the assembly line to process hanging items. This setting can ensure that electronic tag readers are installed at the entrance, exit and turning points of the assembly line. The electronic tag reader can read the identification code of the corresponding hanging tool. The system's master control server can locate the location of the hanging tool and plan the path of the hanging tool based on the type of items currently mounted on the hanging tool and the processing status.

[0081] A method for intelligent process path planning is executed by a general control end, including: S101. Based on the style classification of the order model, determine whether the same style classification exists. If so, determine the same process path. If not, match the process flow of similar style classification; S102. Match the production sequence of the sections, processes, equipment and components of the order model according to the process flow; merge processes according to the same components and the same equipment types, generate process combinations and pre-combination sequences of corresponding components, and form a process path by combining the processes of each section with the corresponding equipment stations.

[0082] The order model primarily defines the following tags, which are formed by parsing and classifying customers and their needs. Specifically, detailed analysis and classification of customers and their needs form the individual tags of the order model, and by defining and assigning values ​​to these tags, the customized needs of different customers are determined. This approach establishes an order model, digitizing and vectorizing traditional customer and demand information, facilitating intelligent and automated process path planning, saving manpower and maximizing human efficiency, thereby facilitating the realization of smart factories. The order number is assigned by the manufacturer; style classification is captured by image acquisition equipment based on samples provided in the customer's demand information; and all other tag content can be derived based on the customer and demand information.

[0084]

[0085]

[0086] Based on the style classification of the order model, the order is broken down into sections, primarily categorized into cutting, sewing, special machine tools, and finishing. Each section is broken down into process steps, such as sleeve center seam, side seam, and sleeve seam. The required equipment for completing the corresponding process is determined, along with the components within the style classification that the equipment processes. These components comprise the product categories within that style classification, such as sleeves, pockets, zippers, collars, and caps for a men's work jacket. This determines the sections, processes, equipment, and components required to produce the order model. In one specific implementation, seven sections are defined, including cutting, sewing, special machine tools, filling, quilting, finishing, and quality inspection. Each section is broken down into 150 process steps, such as sleeve center seam, side seam, sleeve seam, and shoulder seam. 47 types of equipment are required for production, including cutting tables, carts, ironing tables, cutting machines, and button presses.

[0087] Once we know the style classification of the order model, we can determine the process flow based on the work sections, processes, equipment, and components required to process that style classification. Specifically, the process flow determines the overall processing sequence for that style classification, including the order in which the required work sections, processes, equipment, and components are executed. To this end, we use the order model formed by the customer and their demand information as an analogy. Based on the work sections, processes, equipment, and components determined by the style classification of the order model, we form a process flow model, including several tags, as shown in Table 2.

[0088] Table 2 Label description of process flow model

[0089] Serial number Label illustrate 1 Process number Mainly determine the order of the overall process flow 2 Style Classification According to different styles, the corresponding process can be matched 3 Part Name Determine the part name in each process 4 Device Type Determine the type of equipment corresponding to each process

[0090] A process refers to the order of work, which is detailed to the final level of component processing. A technique refers to the process of applying the sleeves first and then the front piece. For the sleeve application process, this can include 1-N processes. The same component can undergo different processes on the same equipment. For example, a sleeve on a sewing machine requires the sleeve center seam and sleeve seam to be processed. These processes can be combined to form a process combination. If a component must complete a certain process on the same or different equipment before proceeding to other processes, this is called a pre-process. For example, a sleeve must complete the hemming process on a sewing machine before completing the sleeve center seam and sleeve seam on the same equipment. These processes can be combined to form a pre-process combination.

[0091] The equipment corresponding to the processes in each section is located at different workstations. To complete the corresponding process flow for an order, it is necessary to perform processing in a certain sequence on different equipment. Because different equipment is distributed at different workstations, processing is required at different workstations. The corresponding process flow is completed according to the individual pieces in the order, and the routes at different workstations form a process path.

[0092] Traditionally, order process flows are manually planned and determined. However, this intelligent planning method, when initially implemented, performs initialization, pre-storing historical order and process flow models in a database. When a new order arrives, an order model is created and the database is searched based on the style classification of the order model. If an order model with the same style classification exists, the process path for the new order model is simply matched to that of the order model. In other words, the new order model eliminates the need for process path planning and can simply be processed using the order's process path, saving significant labor and enabling rapid matching and maximizing human efficiency. If an order with the same style classification does not exist, a process flow with a similar style classification is matched. The process path corresponding to the previous process flow is then adjusted based on the process sections, processes, equipment, and components required by the new order model's style classification. Processes are merged based on the same components and equipment types, generating a process combination and pre-combination sequence for the corresponding components. The process path is then formed by combining the corresponding equipment locations for each process section. This approach allows for rapid determination of the order model's process path, saving labor and achieving factory intelligence.

[0093] For process merging, in an optional implementation, if A, B, C, D…N is a combination of processes that can be merged, the standard working hours corresponding to each process are recorded as X1, X2, X3, X4, X5…Xn respectively, where the standard working hour variance after any N process combination = (1 / n)[(x1-M)^2+(x2-M)^2+.......+(xn-M)^2], the average working hour of the process is set to M, unit: s; N and n are both integers, and the one with the smallest standard working hour variance is taken as the optimal combination.

[0094] Each work section is split into different processes. Each process includes a number of equipment. A process model is established based on the process information. The labels included in the process model are shown in Table 3.

[0095] Table 3 Labels of process models

[0096]

[0097] By establishing a process model in this way, the process can be digitized and vectorized, which facilitates the intelligent planning of process paths and the intelligent scheduling of orders, thus realizing a smart factory.

[0098] Standard process time = process grade * basic time * fabric grade * number of processes. In a specific application, the average process time can be set to 120 seconds. A combinable process combination adheres to the principle of combining processes for the same components and equipment types, generating corresponding process combinations and pre-combination sequences. The optimal combination with the smallest standard time variance is selected to achieve a production balance rate close to 1 for the factory production line, maintaining an optimal production rhythm and maximizing factory energy efficiency.

[0099] Standard labor price = price per second * process level * basic labor hours * fabric level * number of processes. This is used to calculate the total cost required to complete an order, making it convenient to quickly issue quotations to customers.

[0100] Typically, a factory contains multiple production lines, each with its own order ranking. Order priority can be determined based on a combination of factors, such as order model ranking, quantity, and amount. In one embodiment, a method for intelligent process path planning further includes obtaining, based on the order model priority, the estimated idle time of the equipment corresponding to each work section of the previous priority order model, using this as the start time. This is then combined with the process path to generate a process path for each hanging tool in each work section.

[0101] Each hanging tool carries a component and moves it along the assembly line trough of a factory production line, following the process path. At each workstation, the equipment completes the corresponding process step of the component. The hanging tool is equipped with a positioning or navigation module, such as an electronic tag. This module communicates with a central control system (e.g., a cloud-based system) via an electronic tag reader on the trough. The information read by the electronic tag reader determines the hanging tool's path and position, facilitating its control.

[0102] In addition, this embodiment also establishes a factory model and a production line model. The labels of the factory model are shown in Table 4, and the labels of the production line model are shown in Table 5.

[0106]

[0107]

[0108] By establishing factory models and production line models, it is easier to realize factory intelligence.

[0109] In addition, this embodiment proposes an intelligent scheduling method, which is executed by the master control terminal, including: S201. Obtain the estimated starting idle time of the equipment corresponding to each work section of the previous priority order model after completion as the start time, and generate a process path for each hanging tool in each work section in combination with the process path;

[0110] S202. Match the corresponding process flow according to the style classification of the order model, and match the work sections, processes, and equipment of the order model according to the process flow; calculate the processing time of a product, which is recorded as the total working hours for order production; obtain the route length of the movement of a product on the assembly line according to the process path, and calculate the hanging operation time based on the average speed of the hanging tool; add the processing time of a product and the hanging operation time to obtain the total time for processing a product; daily average output per person = total daily working hours / total working hours for order production; daily output = daily average output per person * number of available workstations; the number of available workstations is determined based on the expected idle number of equipment corresponding to each work section of the previous priority order model at the start time; production cycle = total number of orders produced / daily output; where the total number of orders produced is the total number of products that need to be processed in the order model; the delivery date of the order model is used as the end time; obtain a list of equipment expected to be put into production of the current order model after the corresponding equipment of each work section of the previous priority order model is completed, match the workstation production resources of the order model based on the skill level and number of personnel corresponding to the workstations of the equipment, and mark the start time and end time of the corresponding order model for the equipment and workstation.

[0111] Production cycle = total number of orders / daily output, remove the decimal point and add 1 to the result, round it up, and predict the production cycle to facilitate adjustment of the production line and control the production cycle forecast within the production line. Standard working hours for each process = process level * basic working hours * fabric level * number of processes, where the number of processes refers to the same process that may be operated more than twice. Add the standard working hours corresponding to each process required to process the order model, and then multiply it by the number of orders in the order model to obtain the total working hours for order preparation. Through the above method, intelligent scheduling of orders can be quickly realized, and the start and end times of the order model can be determined, so that the corresponding scheduling information can be quickly fed back to customers, which is convenient for customers to make decisions and facilitates the factory's marketing and customer acquisition.

[0112] For some styles, in addition to working on the assembly line, some sections also require off-line processing. Unlike on-line processing, off-line processing does not require consideration of production balance.

[0113] Combined with the order model, the off-line processing time is calculated based on the off-line process, equipment, and number of workers. The same type of process corresponds to a workstation, and each workstation is then assigned to a person. For off-line processing processes, as an optional implementation, the corresponding workstation matching method includes: If the number of off-line processing processes is greater than the number of idle off-line workstations, then:

[0114] Calculate the number of people required for each process by N*A%, rounding the result. N is the number of available workstations, initially defaulting to all off-line workstations. A% is the total man-hour ratio for each off-line process: A% = standard off-line process hours / total off-line order hours. The sum of the A% ratios for all off-line processes is 1. This formula calculates the number of workstations for each off-line process, rounding the result to the nearest integer.

[0115] Add the number of workers for all off-line processing steps and calculate the rounded sum. If the sum ≤ N, no action is taken. If the sum = N + 1, calculate the number of workers for that step minus 1, and if the sum = N - 1, calculate the number of workers for that step plus 1. Assign the corresponding number of workers to the equipment at the workstations of the corresponding steps. The standard working hours for off-line steps = step level * basic working hours * fabric level * number of steps. Assign workstations and the corresponding number of workers to each step according to the order of the steps. Once each step is fully assigned, assign the next step.

[0116] For example, the processes that need to be processed off-line include two processes, a and b, in the order of a and b. The number of available off-line workstations is N, where N is 10. For process a, the total working time ratio A% = 0.5, and 5 workstations and 5 personnel are arranged at the corresponding workstations; for process b, the total working time ratio A% = 0.5, and 5 workstations and 5 personnel are arranged at the corresponding workstations.

[0117] If for process a, the total working time ratio A% = 0.42, after rounding, 4 workstations and 4 personnel are arranged at the corresponding workstations; for process b, the total working time ratio A% = 0.58, 6 workstations and 6 personnel are arranged at the corresponding workstations.

[0118] If for process a, the total working time ratio A% = 0.73, after rounding, 7 workstations and 7 people are arranged at the corresponding workstations; for process b, the total working time ratio A% = 0.27, 3 workstations and 3 people are arranged at the corresponding workstations.

[0119] One process is completed by one device. The process and the device correspond to each other. One device is set up at each off-line workstation. If the number of off-line processing processes is less than the number of idle off-line workstations, the off-line workstation is directly allocated to the corresponding process.

[0120] Calculate the required resource types: Split the work section into processes, such as splitting the sewing section into processes, and match the required production equipment types according to the processes. This is obtained through the process model's stage, process classification, and equipment type.

[0121] Establish equipment and workstation models, and include corresponding tags, as shown in Tables 6 and 7. This approach digitizes and vectorizes equipment and workstations, improving factory intelligence, reducing manpower, improving labor efficiency, increasing production capacity, and maximizing energy efficiency.

[0127] Calculate the order start time: Calculate the time it takes for all conditions to be met, assuming the minimum production unit (i.e., the minimum production unit required to produce a complete garment) to be met. This is calculated based on the estimated idle time of all equipment required to produce a garment. This is used as the start time.

[0128] Calculate the order end time: start time + order model delivery time.

[0129] Calculate the number of required resources: Based on the delivery period of the order model and the required resource types, use the workstation model to obtain a list of equipment that can be put into production. Based on the daily working hours of the equipment, while excluding rest time, the specific number of resources required to produce this order can be determined.

[0130] Calculate the required number of personnel: Based on the personnel skill levels and the workstation model, match the final workstation production resources and mark the resources. The resources cannot be occupied by other orders during other time periods. In other words, define the equipment model's operating status and the workstation model's operating status.

[0131] Other calculations: If the existing resources do not meet the production requirements or partially meet the production requirements, the calculation will be based on the existing resources, and the order end time will be based on the calculated end time.

[0132] In an alternative implementation, if the order is reviewed, the order is then ranked first based on the work stage type. If it is, the estimated completion time of the latest completed work stage task in the ongoing state is used (estimated completion time = start time + production cycle time). If it is not, the planned end time of the work stage task in the previous priority order model is used as the start time.

[0133] Through intelligent scheduling and optimized process paths, the suspended assembly line can more efficiently utilize resources, reduce waste, speed up production, and improve production efficiency. The intelligent scheduling method of this embodiment can quickly adapt to changes in market demand, support personalized and small-batch production, and provide more flexible production options and agile production processes.

[0134] The intelligent planning and scheduling methods of this embodiment, through data analysis of customer and demand information, achieve more reliable predictability of production plans and outputs for factory production lines, while also improving transparency of the entire production process. This optimizes energy and material usage, reduces production costs, and promotes sustainable development by improving energy and material efficiency. Through real-time data tracking, intelligent assembly lines can more effectively manage inventory, reduce the risk of oversupply and shortages, and optimize inventory management. With improved supply chain data integration capabilities, suspended assembly lines can more effectively respond to changes in raw material supply and market demand.

[0135] like Figure 12 ,This embodiment proposes an intelligent scheduling method, which is executed by a hanging tool terminal, including: S101. The hanging tool receives its own process path sent by the master control terminal, executes the process path in sequence, and automatically moves to the corresponding workstation;

[0136] S102. The hanging tool enters the workstation, the electronic tag reader reads the electronic tag of the hanging tool and sends it to the master control terminal, marking the status of the hanging tool as entering the station;

[0137] S103. After the hanging tool completes the corresponding process at the station, the station electronic tag reader feeds back to the master control terminal, which marks the status of the hanging tool as having completed the corresponding process;

[0138] S104. The hanging tool comes out of the workstation, the electronic tag reader reads the electronic tag of the hanging tool and sends it to the master control terminal, which marks the status of the hanging tool as outbound;

[0139] S105. Determine if the process path for the current level is complete. If so, the hanging tool moves to the next level. Based on the workstation model, the least busy workstation in the current level is selected for scheduling. Repeat S201-S104, and the hanging tool moves to that workstation to complete the corresponding process.

[0140] If not, the most idle workstation at the current level is selected according to the workstation model, and scheduling is performed. S301-S302 are repeated, and the hanging tool is moved to the workstation to complete the corresponding process processing;

[0141] S106. The master control terminal receives data from the distance sensor on the hanging tool and the electronic tag reader on the assembly line tank, and makes a comprehensive judgment. If a station is congested, the master control terminal searches for a universal station in the hierarchy of the current process path. If so, the hanging tool is diverted and S301-S302 are repeated. If not, a warning message is issued;

[0142] Among them, S106 is not limited by the execution order of the above steps.

[0143] The hanging tool involved in this embodiment has a self-driving function, such as achieved by setting a self-driving tire; and has the ability to communicate with the main control end, such as achieved by setting a processor, a wireless communication module and other conventional communication devices. The main control end receives the data read by the distance sensor on the hanging tool and the electronic tag reader on the assembly line trough body, and can determine the position of each hanging tool based on the pre-stored assembly line trough body and the electronic tag reader layout diagram thereon; based on the information sent back by the distance sensor of each hanging tool, it can be determined whether the hanging tool parked at a certain workstation is in a congested state. The judgment standard for the congestion state here is: the time it is expected that the workstation will take to complete the components loaded by each hanging tool there is much longer than other workstations, that is, the actual production balance rate and the target production balance rate do not match. The specific level of the gap between the two can be preset at the main control end and is not limited by this embodiment. If congestion occurs, the master control end adjusts the hanging tools to other idle workstations. When selecting the most idle workstation, it makes a judgment based on the operating status of the workstation model and the expected idle time. If the operating status of the current workstation is not idle, the workstation with the earliest expected space time is determined to be the workstation with the most space. During the order production and processing process, this step is controlled in real time by the master control end and is not restricted by the aforementioned processing sequence to achieve the best production balance rate, thereby ensuring the maximum energy efficiency of the factory production line. The scheduling method of this embodiment is applied to a suspended assembly line, which integrates big data and intelligent analysis tools, can monitor the production process in real time, perform real-time data analysis, quickly identify and solve problems, and improve production quality. The assembly line to which the scheduling method of this embodiment is applied has the characteristics of automation and intelligence, reduces dependence on manual operation, reduces manual intervention and errors, reduces the possibility of human error, and improves overall operational safety.

[0146] Optionally, the method for diverting hanging tools includes: based on the total balance calculation of congested hanging tools, the main control end sends diversion information including the position of the universal workstation to the diverted hanging tool; after receiving the diversion information, the hanging tool moves out of the congested workstation; the electronic tag reader reads the electronic tag of the hanging tool, marking the hanging tool status as outbound, and the corresponding processing step is not completed; the hanging tool enters the corresponding diverted universal workstation, and repeats S301-S302.

[0147] The status of the hanging tools is marked by the master control end, which facilitates the master control end to globally control and coordinate the production lines and orders, and strives to achieve a production balance rate close to 1 to maximize the efficiency of the factory production line.

[0149]

[0150] The aforementioned all-round workstation possesses the skills of various types of workstations on the production line and can perform each process. This workstation includes the equipment required for each process, and the employees assigned to this workstation also possess the corresponding skills. To facilitate management and the implementation of smart factories, this embodiment establishes an employee model. The employee model includes a basic model, a skills model, and a values ​​model. The labels corresponding to each model are shown in Tables 8, 9, and 10.

[0153] This embodiment proposes an intelligent scheduling method, which is executed by the master control end, including: S301. Sending the corresponding process path to the hanging tool; that is, the master control end sends the planned process path of each component to the hanging tool that uniquely matches each component, and the hanging tool loads the component to execute the corresponding path.

[0154] S302. The electronic tag reader at the receiving entrance reads the electronic tag of the hanging tool, marking the status of the hanging tool as inbound; the receiving station electronic tag reader reads the electronic tag of the hanging tool, marking the status of the hanging tool as having completed the corresponding process; the electronic tag reader at the receiving exit reads the electronic tag of the hanging tool, marking the status of the hanging tool as outbound;

[0155] S303. If a certain workstation is congested, the master control terminal searches for an all-purpose workstation in the hierarchy of the current process path. If so, the hanging tools are diverted and S301-S302 are repeated. If not, a warning message is issued. S106 is not restricted by the execution order of the above steps.

[0156] Optionally, the method for diverting hanging tools includes: based on the total balance calculation of congested hanging tools, the main control end sends diversion information including the position of the universal workstation to the diverted hanging tool; after receiving the diversion information, the hanging tool moves out of the congested workstation; the electronic tag reader reads the electronic tag of the hanging tool, marking the hanging tool status as outbound, and the corresponding processing step is not completed; the hanging tool enters the corresponding diverted universal workstation, and repeats S301-S302.

[0157] Specifically, the traffic information sent by the master control terminal includes the location of the universal station, the path the hanging tool will take to reach it, and the speed at which the hanging tool will move to it. If the hanging tool's processor has sufficient computing power, the master control terminal only needs to send the universal station location; the hanging tool will calculate the remaining two items. Because the master control terminal possesses global coordination and control capabilities, this information is generally handled by the master control terminal.

[0158] This embodiment provides an intelligent system for storing or executing any one of the methods described above, which can be set on a hanging tool, or on a master control terminal, as well as a work station and an assembly line tank to cooperate in implementing the corresponding method content.

[0159] The technical solution of the embodiment of the present application realizes intelligent process flow planning, intelligent path design and scheduling, which can greatly improve the production efficiency of the factory and maximize the factory's production capacity.

[0160] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
