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 method and system for assembly line and intelligent scheduling, process path planning and scheduling. 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, the suspended conveyor line system faces several technical challenges, especially in the movement of the conveying mechanism. This system is generally driven by an electric chain, so that the items can only move in a single direction within a fixed track. Although this design promotes the continuity of the production process in some aspects, it presents several key inconveniences under the requirements of intelligent manufacturing.

[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-direction movement and fixed track design greatly reduce this flexibility.

[0005] Secondly, the fixed-speed movement mode does not match the demand for variable speed and dynamic adjustment in intelligent manufacturing. In intelligent production, different stages and workstations may require different processing speeds, and the fixed-speed conveyor system cannot meet this demand, which may lead to inefficiency and production delays.

[0006] In addition, the scheduling of items between multiple lines is also affected in this system. Intelligent industrial production requires the system to be able to quickly adjust and reorganize to optimize the production process, but the one-way and closed track design makes cross-line scheduling inefficient, limiting the flexibility and response speed of overall production.

[0007] In short, intelligent industrial production places high demands on the flexibility, adaptability and dynamic adjustment capabilities of system scheduling, while traditional suspended conveyor line systems have obvious limitations in these aspects, requiring 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.

Multiple technical solutions in the same embodiment, and multiple technical solutions in different embodiments, can be arranged and combined to form new technical solutions without contradiction or conflict, all of which are within the scope of protection claimed by the present invention.

[0054] Combination 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 plurality of workstations are distributed in the assembly line trough body, equipment is provided on the workstation, 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 workstation are provided with electronic tag readers, the equipment and the electronic tag reader are connected to the main control terminal, and the power supply is connected to 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, LF / HF tags. The corresponding electronic tag readers are: RFID reader, NFC reader, barcode scanner, Bluetooth reader, UHF reader, LF / HF reader.

[0056] The power supply is for 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 flow requirements of different items, which can meet the cross-line operation and cooperate with the self-driven hanging tool, which is conducive to improving the efficiency of the production link and has great adaptability to the production line.

[0057] An assembly line adopting the technical solution of this embodiment, 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, the item information carried by the hanging tool, the item processing status, 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 item 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 being offset or derailed during movement. The conductive belt 6 provides electric energy for the self-driving of the hanging tool by contacting with the hanging tool. The hanging tool can adjust its own moving speed and moving direction on the assembly line. When the items loaded by the hanging tool need to be dispatched from one production line to another, the hanging tool can realize cross-line operation at the shortest distance and the fastest speed because its moving speed and direction are adjustable, so as to improve the efficiency of the corresponding production link. In addition, the assembly line tank can be adjusted according to the needs of the production line, and has strong adaptability. The situation in the prior art that the movement state of the hanging tool is changed by relying on the assembly line is changed, and the structure of the assembly line is transformed. The assembly line provides electric energy for the self-driven hanging tool, so that the hanging tool can change its own movement state according to the production and processing needs of the loaded items, and is no longer restricted by the assembly line structure. The self-driving hanging tool of this embodiment 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. 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 part of the main assembly line in the hanging assembly line system. The assembly line trough is usually made of high-strength, corrosion-resistant materials such as carbon steel, stainless steel or aluminum alloy. These materials ensure the firmness and durability of the assembly line trough, and can withstand long-term heavy loads and various challenges in industrial environments.

[0059] The cross-sectional shape of the assembly line trough is usually rectangular or a special geometric shape, designed to adapt to different mounting requirements and space constraints. Its size will vary according to the load capacity and application scenario to adapt to different industrial applications and space layouts.

[0060] The interior of the flow line tank 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 overall assembly line.

[0062] In areas subject to greater loads, the flowline tank 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, such as special surface treatments such as galvanizing, spraying or anodizing, which not only improves the durability of the assembly line trough, but also helps reduce maintenance requirements; design easy-to-clean surfaces to ensure efficient and reliable operation of the hanging assembly line system.

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

[0065] The slideway 2 is a cavity located in the flow line trough body, which is used to guide and support the mounting parts or hanging tools such as hanging tools, pulleys or sliders moving along the flow line trough body to ensure its smooth operation. The slideway 2 can be square, concave or convex to adapt to the design of the hanging tool. The surface is smooth to reduce friction. Wear-resistant materials such as hardened steel or special alloys are used to resist wear and tear during 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 cooperating with the connecting rod of the hanging tool, and is a long gap so that the connecting rod can pass smoothly through it, allowing the hanging tool to run along a predetermined track to prevent derailment.

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

[0068] The conductive belt 6 is connected to the power supply, and the material of the conductive belt 6 can be known conductive materials such as aluminum and copper; the insulating layer 5 is made of known insulating materials such as rubber. In a specific embodiment, the conductive belt 6 is a protruding strip, and the insulating layer 5 wraps the conductive belt 6, leaving only the part that is in direct contact with the power supply terminal of the hanging tool drive unit exposed. The conductive belt 6 of the technical solution of this embodiment is reliably conductive, and no additional electrical lines and control lines need to be laid inside the assembly line tank, which is convenient for maintenance and repair.

[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 assembly line 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 of several of them, such as Figure 4-10 As shown, the curved line trough body and the straight line trough body intersect, and an electronic tag reader is provided on the straight line trough body at a set distance at the intersection.

[0071] The pipeline trough bodies of different shapes make the pipeline structure segmented and modular, which is convenient for assembly, installation and disassembly, so that it can flexibly adapt to the needs of different production lines and has strong adaptability. The linear pipeline trough body 11 is provided with a linear 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 assembly line tank body 1 indicated in the figure 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 the 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 is used to weigh the hanging tool, and is in direct contact with the conductive belt 6, so the conductivity is reliable. The conductive belt 6 is arranged on the bearing surface 4, which occupies a small space, reduces the contact area between the hanging tool and the assembly line, and reduces the energy consumption caused by friction. Depending on the design of the power supply terminal of the hanging tool, the conductive belt 6 can exist only on one side of the two sides of the guide groove, and not on the other side; or exist on both sides, which is within the general expression scope of the present embodiment.

[0073] In an optional embodiment, the conductive belt 6 is arranged on the inner side of the assembly line slot body opposite to the guide slot. The conductive belt 6 is arranged here, and when the hanging tool contacts the conductive belt 6 in the guide slot, the power supply terminal on the conductive belt 6 can contact the conductive belt 6 to directly supply power or charge the hanging tool to meet its own power needs.

[0074] As one of the implementation methods of this embodiment, when the assembly line tank 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 matching therewith are not shown in consideration of the simplified 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 line-shaped guide groove 32 and a straight line-shaped guide groove 31, the curved line-shaped guide groove 32 and the straight line-shaped 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 line-shaped guide groove 32. In a specific production environment, a hanging tool assembly warehouse, an article collection warehouse or a processing station for hanging tools to load articles is generally provided below the inlet and outlet. Through the inlet and outlet and the curved line-shaped 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 line-shaped guide groove 31 according to the set path. It can also come out from the slide 2 along the curved line-shaped guide groove 32 through the inlet and outlet, so as to perform corresponding production and processing operations on the articles.

[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 line shaped assembly line trough body 12 and a straight line shaped assembly line trough body 11, and the interface of the curved line shaped assembly line trough body 12 is connected to the side of the straight line shaped 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., turning from a straight-line assembly line trough 11 to another assembly line trough in the assembly line. The corresponding hanging objects enter the curved guide groove 32 from the straight-line guide groove 31 through the connection between the two, completing 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, such as Fig. 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 changed to 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, such as four, three, two or one curved assembly line troughs 12, depending on the specific production line processing flow requirements. In specific applications, the above-mentioned assembly line troughs of different shapes can be combined, not limited by the examples in this embodiment.

[0079] As one of the implementation methods of this embodiment, the curved guide groove 32 and the straight guide groove 31 intersect, and an electronic tag reader is provided on the straight line trough body 11 at a set distance at the intersection, which is not shown in the attached drawings. To optimize the wiring scheme, the electronic tag reader is provided on the straight line trough body 11, and the conductive strip 6444 is wrapped by the insulating layer 5 and extends to the installation position of the electronic tag reader, and is connected to the power line of the electronic tag reader. The electronic tag reader reads the code or identification code of the hanging tool with the electronic tag passing through its position, and the electronic tag reader transmits the signal to the external master control server, host computer, industrial computer, etc. through the wireless module. The electronic tag can choose to use RFID tags, NFC tags, barcode tags, etc., and the codes of these electronic tags can be read by the electronic tag reader provided on the assembly line, so as to accurately locate and track the location of the hanging tool. The electronic tag can be set on the inner wheel, tire, middle rod, etc. of the wheel, so as to facilitate the 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 the hanging objects. This setting ensures that electronic tag readers are installed at the entrance, exit and turning points of the assembly line. The identification code of the corresponding hanging tool can be read by the electronic tag reader. The system's master control server can locate the location of the hanging tool and plan the path of the hanging tool according to the type of items currently mounted on the hanging tool and the processing status.

[0081] A method for intelligent planning of a process path is executed by a general control end, comprising: S101. According to the style classification of an order model, determine whether there is an identical style classification. If so, determine the identical process path. If not, match the process flow of similar style classifications; S102. Match the production sequence of 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 in combination with the process of each section corresponding to the equipment station.

[0082] The order model mainly defines the following labels, which are formed by analyzing and classifying customers and their needs; that is, analyzing and classifying customers and their needs in detail to form the labels of the order model, and defining and assigning values ​​to the labels to form customized needs of different customers. In this way, an order model is established to digitize and vectorize the information about customers and their needs in the traditional model, which is convenient for intelligent and automated process path planning, saving manpower, and maximizing labor efficiency, thus facilitating the realization of intelligent factories. Among them, the order number is assigned by the production and processing party; the style classification can be obtained by the image acquisition device based on the samples provided in the customer demand information; the content of other labels can be obtained based on the customer and his demand information.

[0083] Table 1 Labels of the order model

[0084]

[0085]

[0086] According to the style classification of the order model, the order is divided into sections, mainly into cutting, sewing, special machine, tail and other stages. The process is divided into each section, such as sleeve center seam\side seam\sleeve seam, etc. The required equipment and the parts included in the style classification processed by the equipment are determined by completing the corresponding process. The parts are used to constitute the category of the style classification, such as the parts of men's work clothes include: sleeves, pockets, zippers, collars, hats, etc. The sections, processes, equipment and parts required to produce the order model are thus determined. In a specific implementation, 7 sections are defined, including: cutting, sewing, special machine, filling, quilting, tail, quality inspection; the process is divided into each section, and the process includes 150, such as: sleeve center seam\side seam\sleeve seam\shoulder seam, etc.; the equipment required for production, a total of 47 types of equipment, such as: cutting table, canning car, ironing table, cutting car, buttoning machine, etc.

[0087] After knowing the style classification of the order model, the process flow can be determined according to the work sections, processes, equipment and components for processing the style classification, that is, the process flow is used to determine the overall processing sequence of the style classification, including the execution sequence of the work sections, processes, equipment and components required for processing. To this end, analogous to the order model formed by the customer and its demand information, the process flow model is formed according to the work sections, processes, equipment and components determined by the style classification of the order 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 No. Mainly determine the sequence of the overall process flow 2 Style classification According to different styles, the corresponding process can be matched 3 Part Name Determine the name of the part in each process 4 Device Type Determine the type of equipment for each process

[0090] The process refers to the working order, which is the last level of component processing. The process refers to the process of putting on the sleeves first and then making the front piece. For the process of putting on the sleeves, it can include 1-N processes. The same part is processed in different processes on the same equipment. For example, the sleeves need to complete the processing of the sleeve center seam and sleeve seam on the sewing machine. They can be combined to form a process combination. If the same part needs to complete a certain process on the same / different equipment before other processes can be carried out, it is called a pre-process. For example, the sleeves need to complete the process of pressing the edge on the sewing machine, and then complete the processing of the sleeve center seam and sleeve seam on the same equipment, that is, the sewing machine. They can be combined together to form a pre-combination.

[0091] The equipment corresponding to the process of each work section is at different workstations. To complete the corresponding process flow for an order, it is necessary to carry out processing in a certain sequence on different equipment. Since different equipment is distributed at different workstations, processing needs to be carried out at different workstations. The corresponding process flow is completed according to the single piece in the order, and the route at different workstations forms a process path.

[0092] In the traditional mode, the process flow of an order is determined by manual planning; at the beginning of implementation, this intelligent planning method can be initialized and the historical order model and the historical process flow model can be pre-stored in the database; when a new order comes in, an order model is established, and the database is searched according to the style classification of the order model. If there is an order model with the same style classification, the process path of the new order model can be directly matched with the process path of the order model. In other words, the new order model does not need to be planned for the process path, and the process path of the order can be directly used for processing, which saves a lot of manpower, can achieve fast matching, and maximize labor efficiency. If there is no order with the same style classification, the process flow of similar style classification is matched; then, combined with the process sections, processes, equipment and components required by the process flow of the style classification of the new order model, the process path corresponding to the previous process flow is adjusted, and the processes are merged according to the same parts and the same equipment types, and the process combination and pre-combination sequence of the corresponding parts are generated. Combined with the process of each section corresponding to the equipment station, the process path is formed. In this way, the process path of the order model can be quickly determined, saving manpower investment and realizing the intelligence of the factory.

[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, thereby realizing a smart factory.

[0098] Standard working time of a process = process grade * basic working time * fabric grade * number of processes. In a specific application, the average working time of a process can be set to 120s. A process combination that can be combined refers to the principle of combining processes according to the same components and the same equipment type to generate process combinations and pre-combination sequences for the corresponding components. Taking the minimum standard working time variance as the optimal combination method can achieve a production balance rate of the factory production line close to 1, maintain the best production rhythm, and thus maximize the factory's energy efficiency.

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

[0100] Generally, a factory contains multiple production lines, each of which has its own order ranking. The order priority ranking can be determined based on the order model ranking, quantity, amount, etc. In a specific embodiment, a method for intelligent planning of a process path also includes obtaining the estimated starting idle time of the equipment corresponding to each section of the previous priority order model according to the priority of the order model as the start time, and generating a process path in each section for each hanging tool in combination with the process path.

[0101] Each hanging tool carries a component, and the hanging tool carries the component in the assembly line tank of a certain production line in the factory, and moves along the process path. At each station, the equipment completes the corresponding process of the component. The hanging tool carries a functional module with positioning or navigation, such as an electronic tag, which communicates with the master control end through the electronic tag reader on the waterline tank. The master control end can be located in the cloud, etc., and the travel path and position of the hanging tool are determined according to the information read by the electronic tag reader, so as to facilitate the master control end to control the hanging tool.

[0102] In addition, this embodiment also establishes a factory model and a production line model. The label of the factory model is shown in Table 4, and the label of the production line model is 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 end, including: S201. Obtain the estimated starting idle time of each work section corresponding to the equipment of the previous priority order model after completion, as the start time, and generate a process path in each work section for each hanging tool 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 section, process 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 making an order; obtain the route length of a product moving on the assembly line according to the process path, and calculate the hanging operation time in combination with the average speed of the hanging tool; add the processing time of a product to the hanging operation time to get the total time for processing a product; daily average output per person = total working hours per day / total working hours for making an order; daily output = daily average output per person * number of available workstations; the number of available workstations is determined according to the estimated 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 / daily output; among which, the total number of orders is the total number of products that need to be processed in the order model; take the delivery date of the order model as the end time; obtain the list of equipment expected to be put into the 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 in combination with the skill level and number of personnel corresponding to the workstation 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 integer, predict the production cycle, 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, which may be operated more than 2 times. 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 get the total working hours for order preparation. In the above way, intelligent scheduling of orders can be quickly realized, and the start and end times of the order model can be determined, so as to quickly feedback the corresponding scheduling information to customers, facilitate customer decision-making, and facilitate the factory's marketing and customer acquisition.

[0112] For some styles, in addition to working on the assembly line, some sections also need to process the corresponding processes outside the assembly line. Unlike processing on the assembly line, processing outside the assembly line does not need to consider the problem of production balance rate.

[0113] Combined with the order model, the time required for off-line processing is calculated based on the off-line processes, equipment, and number of workers. The same type of process corresponds to a workstation, and then a workstation corresponds 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 off-line idle workstations, then:

[0114] Calculate the number of people for each process = N*A%, and round the result. Among them, N is the number of available workstations, which is initially defaulted to all the workstations outside the current line; A% is the total working time ratio of each process outside the line, A% = standard working time of the process outside the line / total working time of the order outside the line, and the sum of the total working time ratio A% of all processes outside the line is 1. According to this formula, the number of workstations for each process outside the line can be calculated, and this result is the result of rounding the above formula.

[0115] Add up the number of workers in all off-line processing procedures and calculate the rounded sum. If the sum is ≤N, no processing is done; if the sum is =N+1, calculate the last rounded workstation number -1 as the number of workers for the process; if the sum is =N-1, the last rounded workstation number +1 is used as the number of workers for the process, and arrange the corresponding number of workers at the equipment at the workstation of the corresponding process, where the standard working hours of the off-line process = process level * basic working hours * fabric level * number of processes. Allocate workstations and the corresponding number of workers at the workstations according to the order of the processes, and allocate the next process after each process is fully allocated.

[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 personnel are arranged at the corresponding workstations; for process b, the total working time ratio A% = 0.27, 3 workstations and 3 personnel are arranged at the corresponding workstations.

[0119] One process is completed by one device. The process corresponds to the equipment. One device is set up at each off-line workstation. If the number of off-line processing processes is less than the number of off-line idle 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 type according to the process, that is, obtain it through the stage of the process model, process classification and equipment type.

[0121] Establish equipment models and workstation models, and the corresponding tags are shown in Tables 6 and 7. In this way, the equipment and workstations are digitized and vectorized, which improves the intelligence of the factory, reduces manpower, improves the labor efficiency, increases production capacity, and maximizes the energy efficiency.

[0127] Calculate the order start time: Calculate the time when all conditions are met to meet the minimum production unit, that is, to fully produce a piece of clothing, based on the resources required to produce a piece of clothing - the estimated idle time of all the equipment required. As the start time.

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

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

[0130] Calculate the number of personnel required: According to the personnel skill level and the workstation model, match the final workstation production resources and mark the resources. The resources cannot be occupied by other orders in other time periods, that is, define the equipment operation status of the equipment model and the operation status of the workstation model.

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

[0132] In an optional implementation scheme, if the order review is completed, then according to the type of work section included in the order, determine whether the corresponding work section is currently ranked first? If yes, then take the estimated completion time of the latest completed work section task in the ongoing state, and the estimated completion time = start time + production cycle; if no, then the planned end time of the work section task of the previous priority order model is used as the start time.

[0133] Through intelligent scheduling and optimized process paths, the suspended assembly line can use resources more efficiently, 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 flexible production processes.

[0134] The intelligent planning method and intelligent scheduling method of this embodiment can achieve more reliable predictability of the production plan and output of the factory production line through data analysis of customer and demand information, while improving the transparency of the entire production process; thereby optimizing the use of energy and materials, reducing production costs, and at the same time being conducive to sustainable development and improving energy and material efficiency. Through real-time data tracking, intelligent assembly lines can manage inventory more effectively, reduce the risk of excess and shortage, and optimize inventory management. With better supply chain data integration capabilities, suspended assembly lines can respond more effectively to changes in raw material supply and market demand.

[0135] like Fig.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, and 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, and the master control terminal marks the status of the hanging tool as having completed the corresponding process;

[0138] S104. The hanging tool comes out of the workstation, and 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 whether the process path of the current level is completed. If so, the hanging tool moves to the next level, selects the most idle station in the current level according to the station model, and performs scheduling. Repeat S201-S104, and the hanging tool moves to the station to complete the corresponding process processing;

[0140] If not, the idlest station in the current level is selected according to the station model for scheduling, and S301-S302 are repeated. The hanging tool is moved to the station to complete the corresponding process processing;

[0141] S106. The master control terminal receives the data read by the distance sensor on the hanging tool and the electronic tag reader on the assembly line tank body and makes a comprehensive judgment. If a certain 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 by setting a self-driving tire; and has the ability to communicate with the main control end, such as 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 according to the pre-stored assembly line trough body and the electronic tag reader layout diagram thereon; according to 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 at this location is far longer than other workstations, that is, the actual production balance rate does not match the target production balance rate. The specific difference level 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 workstations 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 errors, 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 master control end sends diversion information including the position of the universal workstation to the diverted hanging tools; after receiving the diversion information, the hanging tools move out of the congested workstation; the electronic tag reader reads the electronic tag of the hanging tools, marking the status of the hanging tools as outbound, and the corresponding processing step is not completed; the hanging tools enter the corresponding diverted universal workstation, and repeat S301-S302.

[0147] The status of the hanging tools is marked by the master control end, which facilitates the global control and coordination of production lines and orders, and strives to make the production balance rate approach 1 to achieve maximum efficiency of the factory production line.

[0149]

[0150] The above-mentioned all-round workstation, that is, the workstation has the skills of various types of workstations on the production line and can realize each process. The workstation contains the equipment required for each process, and the employees matched with the workstation also have the corresponding skills. In order to facilitate management and realize intelligent factories, this embodiment establishes an employee model, which includes a basic model, a skill model, and a value 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 electronic tag reader at the receiving station 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 end searches whether there is 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; wherein, 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 master control end sends diversion information including the position of the universal workstation to the diverted hanging tools; after receiving the diversion information, the hanging tools move out of the congested workstation; the electronic tag reader reads the electronic tag of the hanging tools, marking the status of the hanging tools as outbound, and the corresponding processing step is not completed; the hanging tools enter the corresponding diverted universal workstation, and repeat S301-S302.

[0157] Specifically, the diversion information sent by the master control terminal includes: the position of the universal workstation, the path of the hanging tool to the universal workstation, and the moving speed of the hanging tool to the universal workstation. If the processor of the hanging tool has a certain computing power, the master control terminal only needs to send the position of the universal workstation, and the latter two data are calculated by the hanging tool itself. Because the master control terminal has the ability of global coordination and control, this part of the content is generally implemented by the master control terminal.

[0158] This embodiment provides an intelligent system for storing or executing any 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.
