Description

Technical Field

[0001] This invention relates to the field of hygiene product production line control technology, specifically a flexible production control system and method based on intelligent manufacturing. Background Technology

[0002] In today's rapidly developing industrial sector, the hygiene products manufacturing industry, as one of the most important sectors in the entire industrial production, is facing unprecedented challenges and opportunities. With the increasing demand for product diversification and customization, the traditional large-scale, single-product production and packaging model can no longer meet market demand. This market trend has led to orders trending towards small batches and multiple varieties. This not only requires production lines to be highly flexible to adapt to the production and packaging of different products, but also requires the ability to quickly adjust production and packaging strategies to meet the increasingly shorter delivery time requirements.

[0003] Flexible co-line production, a key component of intelligent manufacturing, offers significant advantages in more precisely meeting consumer needs, thereby improving production and packaging efficiency. However, in hygiene product manufacturing, traditional assembly lines typically employ fixed layouts optimized for specific products, making it difficult to adapt to changing production demands. Each hygiene product processing location has different components with varying functions, resulting in different packaging protection requirements. Furthermore, existing packaging equipment requires frequent changes in packaging configuration at each processing location, leading to varying degrees of downtime for multiple hygiene products and consequently, low production efficiency. Therefore, designing a flexible production control system and method based on intelligent manufacturing, offering strong packaging control and enhanced hygiene product protection, is essential.

The sanitary products are conveyed by a unified tooling plate, and the conveying path to the target workstation is determined by the host computer management software. The management layer uses Ethernet, and the equipment layer samples the PROFIBUS-DP network, integrating standard-compliant production models and leaving room for secondary upgrades and expansion.

[0021] In some preferred embodiments, the detection module includes: An importance detection module is used to analyze the importance of the processing positions of the sanitary products. The importance of each processing position includes the importance of an individual processing position and the importance of adjacent processing positions. The importance between adjacent processing positions is obtained based on an algorithmic analysis of the connection between the importance of two processing positions. Based on the target production model positioning information, the target production model position data is extracted, and the sanitary product processing positions are located and recorded in the target production model position data. All target production models appearing in the production line adjacent to their processing positions are retrieved from the target production model position data, and the adjacent sanitary product processing positions are located and recorded. The individual sanitary product processing position and the adjacent sanitary product processing positions are recorded using their ranking values. The importance of an individual sanitary product processing position is... Where η is the repetition rate of the processing position of the sanitary products in multiple orders, S is the positional ranking value of the processing position of the sanitary products in the sanitary products production line; and the importance between adjacent processing positions of the sanitary products. ; Demand detection module, the demand detection module is used to detect the demand for hygiene products at the target location.

Both K1 and K2 are variable values.

[0022] In some preferred embodiments, the control module includes: The output module is used to detect the protection level of the target location of the sanitary product based on the analysis results of the demand for the target location of the sanitary product, and output an instruction to protect the target sanitary product. The packaging control module is used to control the hygiene products to be conveyed into the packaging equipment via a conveyor belt. The packaging equipment is equipped with an automatic splicing mechanism, an ultrasonic outer diameter sensor, and a PLC controller. The automatic splicing mechanism is used to automatically complete the splicing of packaging and dispensing materials and the sanitary products. The automatic splicing mechanism includes a feeding device and a pressing mechanism. The ultrasonic outer diameter sensor is a sensor that converts ultrasonic signals into energy signals and issues an alarm signal when a preset detection value is reached. The PLC controller is used to receive information from the ultrasonic outer diameter sensor, trigger output actions, execute instructions for logical operations, sequential control, timing, and counting operations, and control the packaging equipment through digital or analog inputs and outputs. When the ultrasonic outer diameter sensor on the packaging equipment detects that the outer diameter of the hygiene product has reached the alarm range of the ultrasonic outer diameter sensor, the PLC controller counts down for X (X≤60) seconds, and at the same time, the storage rack with storage function begins to store packaging materials; when the PLC controller counts down to Y (Y≤5) seconds, the storage rack begins to release packaging materials, and according to the extraction and recording of multiple components of the hygiene product, the packaging materials are packaged from the inside out. At the same time, the PLC controller controls the speed of the conveyor belt to decrease. After the PLC controller counts down, the sensor starts to work.

After the splicing is completed, the storage rack gradually returns to its original state, and the control conveyor belt gradually speeds up to match the speed of the hygiene product conveying mechanism production line.

[0023] Please see Figure 2 Based on the same concept as the above embodiments, embodiments of the present invention also provide a flexible production control method based on intelligent manufacturing, including: Step S1: Collect production data and online order information of the target hygiene product. The production data of the target hygiene product includes the components and functional components of the target hygiene product. Step S2: Extract and record multiple components of the sanitary product based on the constituent parts and functional parts of the sanitary product in the online order information, and detect the importance of the processing location of the sanitary product based on the production data of the sanitary product; wherein, the components of the sanitary product are extracted by disassembling the sanitary product from the inside out according to the constituent parts and functional parts of the sanitary product; Step S3: Based on the detection results of the importance of the processing location of the hygiene products, obtain the degree of importance of protecting the target location of the hygiene products, and control the packaging equipment to package and protect the hygiene products.

[0024] In this embodiment, the collection of production data and online order information for the target hygiene products includes: Step S101: Set up production models, conveying equipment, and packaging equipment in the production line. The production models and packaging equipment are capable of processing different hygiene products simultaneously. Match the hygiene products with the production models in the database and mark the production data of the target hygiene product with the production models in the production line accordingly. The production models include multiple production models. Each production model has the processing function of processing the components or functional parts of the target hygiene product. The production model controls the robot to execute the processing function. The processing functions of different production models are different. Step S102: Extract the online order information, break down the online order information, and locate the target production model in the online order information among multiple production models based on the production data of the target sanitary products in the online order information; wherein, the target production model is the processed target sanitary products in the online order, and the number of target production models is at least one, and record the positioning information of the target production model, which includes the position data of the target production model and the ranking value of the target production model in the production process of the target sanitary products. The ranking value in the production process of the target sanitary products is the position of the target sanitary products in the positioning information of the production model, including the first value, the second position, ... the nth position.

[0025] In this embodiment, setting up production models, conveying equipment, and packaging equipment in the production line includes: Step S1011: Control the robot to perform loading and unloading operations sequentially between all adjacent production models and packaging equipment in the production line using the production model; Step S1012: The transmission equipment is responsible for transporting the sanitary products to each sanitary product processing position according to different processing paths. The production model control robot is responsible for picking up the sanitary product parts transported to the workstation and placing them into the corresponding sanitary product processing position. The sanitary products are transported by a unified tooling plate. The transport path to the target workstation is determined by the host computer management software to achieve traceability management. Step S1013: The management layer adopts Ethernet, and the device layer samples the PROFIBUS-DP network to integrate the standard-compliant production model, leaving room for secondary upgrades and expansion.

[0026] In this embodiment, detecting the importance of the processing location of the hygiene product includes: Step S21: The importance of the hygiene product processing location includes the importance of a single hygiene product processing location and the importance of adjacent hygiene product processing locations. The importance between adjacent hygiene product processing locations is obtained by algorithm analysis based on the connection between the importance of two hygiene product processing locations. Step S22: Based on the target production model positioning information, extract the target production model position data, locate the sanitary product processing position in the target production model position data, record the individual sanitary product processing position, retrieve all target production models that appear in the production line adjacent to the processing position in the target production model position data, locate the sanitary product processing position adjacent to the processing position and record it, the individual sanitary product processing position and the adjacent sanitary product processing position are recorded using the order value of the sanitary product processing position; Among them, the importance of a single processing location for the hygiene products Where η is the repetition rate of the processing position of the sanitary products in multiple orders, and S is the positional order value of the processing position of the sanitary products in the sanitary products production line; The greater the importance of a single hygiene product processing location, the fewer the types of hygiene product processing locations that are optimal in the preset location, and the greater the probability of finding the optimal solution; the less important the location, the more types of hygiene product processing locations that are optimal in the preset location. The repetition rate of the sanitary product processing position in multiple orders represents how many times the sanitary product processing position is used in the sanitary product production line. The higher the repetition rate, the stronger the irreplaceability of the sanitary product processing position; conversely, the lower the repetition rate, the weaker the irreplaceability of the sanitary product processing position. Therefore, the repetition rate of the sanitary product processing position in multiple orders is directly proportional to the importance of the individual sanitary product processing position. The priority value of a hygiene product processing location within the hygiene product production line indicates whether the hygiene product is processed first or last in the production line. This priority value reflects the underlying logical importance of the processing function corresponding to that location within the production model. A low priority value suggests that the hygiene product needs to perform the processing function first, and placing it later is more likely to increase processing difficulty. Conversely, a high priority value indicates that the hygiene product can perform the processing function later, and placing it later is less likely to increase processing difficulty. Therefore, the priority value of a hygiene product processing location within the hygiene product production line is inversely proportional to the importance of that individual hygiene product processing location. Step S23: The importance of the adjacent processing locations of the hygiene products .

[0027] The higher the total importance value after aggregation, the greater the importance between adjacent sanitary product positions, and the more inseparable the adjacent sanitary product positions are; conversely, the lower the total importance value after aggregation, the less important the adjacent sanitary product positions are, and the more separable the adjacent sanitary product positions are. In this embodiment, the determination of the importance of protecting the target location of the hygiene product includes: Step S301: Demand for hygiene products at target locations Where α is the importance reference level, and the importance reference level is a preset value α, which can classify... The result multiplier is adjusted so that Q0 is a preset reference value for the importance of a single processing position of the sanitary product, and the optimal solution is obtained. K1 is the importance of a randomly selected single processing position of the sanitary product, and K2 is the importance of locating adjacent processing positions of the randomly selected single processing position of the sanitary product. Both K1 and K2 are variable values.

[0028] If the total importance value after superposition is greater than or equal to twice the preset reference value for the importance of a single hygiene product processing position, and the excess value includes the importance that can replace the importance of other hygiene product processing positions, it is used to ensure that the superposition total value of the hygiene product processing positions in the entire production line can exceed the preset minimum value. Whether to add a single hygiene product processing position on the basis of exceeding the preset minimum value is only a further optimization of the hygiene product and will not affect the completion of the hygiene product or the production logic.

[0029] In this embodiment, controlling the packaging equipment to package and protect the hygiene products includes: Step S311: Based on the analysis results of the demand for the target location of the sanitary product, detect the protection level of the target location of the sanitary product and output an instruction to protect the target sanitary product; Step S312: Control the hygiene products to be conveyed into the packaging equipment via a conveyor belt. The packaging equipment is equipped with an automatic splicing mechanism, an ultrasonic outer diameter sensor, and a PLC controller. The automatic splicing mechanism is used to automatically complete the splicing of packaging and dispensing materials and the sanitary products. The automatic splicing mechanism includes a feeding device and a pressing mechanism. The ultrasonic outer diameter sensor is a sensor that converts ultrasonic signals into energy signals and issues an alarm signal when a preset detection value is reached. The PLC controller is used to receive information from the ultrasonic outer diameter sensor, trigger output actions, execute instructions for logical operations, sequential control, timing, and counting operations, and control the packaging equipment through digital or analog inputs and outputs. Step S313: When the ultrasonic outer diameter sensor on the packaging equipment detects that the outer diameter of the hygiene product has reached the alarm range of the ultrasonic outer diameter sensor, the PLC controller counts down for X (X≤60) seconds, and at the same time, the storage rack with storage function begins to store packaging materials; when the PLC controller counts down to Y (Y≤5) seconds, the storage rack begins to release packaging materials, and according to the extraction and recording of multiple components of the hygiene product, the packaging distribution materials are packaged from the inside to the outside. At the same time, the PLC controller controls the speed of the conveyor belt to decrease until the PLC controller finishes counting down. Then, the sensor starts working. When the sensor detects that the automatic splicing mechanism splices the packaging materials to the processing position of the hygiene product, the virtual model of the packaging distribution materials being conveyed is cut off, and the automatic splicing is completed. After the splicing is completed, the storage rack gradually returns to its original state, and the control conveyor belt gradually speeds up to match the speed of the hygiene product conveying mechanism production line.

[0030] The level of protection for the target location of the hygiene product includes the packaging protection location of the target hygiene product during the packaging process and the packaging integrity of the target hygiene product during the packaging process. The packaging protection of the hygiene product includes scope protection and specific protection. Scope protection means protecting the entire hygiene product, while specific protection means providing specific protection for a certain location of the hygiene product. in, The packaging protection locations of the target hygiene products during the packaging process include: The demand for the target locations of the hygiene products is sorted in descending order, and the target locations of the hygiene products are marked according to the descending order. Based on the packaging material allocation data of a single hygiene product preset by the packaging equipment, the packaging material allocation of the single hygiene product is allocated to the target locations of the hygiene products in descending order according to the proportions of W1%, W2%, and (100-W1-W2-G)%, corresponding to the protection level. Wherein, W1 is the preset proportion value of the first importance location area of ​​the hygiene product, W2 is the preset proportion value of the second importance location area of ​​the hygiene product, W1>W2>100-W1-W2, and G is the preset proportion value of the connecting packaging material allocation. The packaging integrity of the target hygiene products described in the packaging process includes: Obtain the difference in importance between adjacent processing locations of the target hygiene products. If R > R0, mark it as the specific protection, and package the target position of the sanitary product according to the packaging protection position of the target sanitary product in the packaging process; otherwise, mark it as range protection, identify the connection area between adjacent processing positions of the sanitary product, control the packaging equipment to package the connection area, and the maximum packaging material allocation ratio value of the connection is G.
