Description

Technical Field

[0001] The present invention relates to the technical field of tire production and manufacturing, and in particular to a tire equipment edge end control system and method. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. The production process includes six steps: mixing, rubber component preparation, tire molding, vulcanization, and final inspection. The rubber component preparation process is to prepare all the semi-finished rubber components that make up the tire, including six main sections. The extrusion section is to mix the rubber to obtain the original sheet rubber, inject it into the rubber barrel, and then extrude it out of the die head under the push of the screw, and pass through the die plate determined by the process standards to obtain the semi-finished products such as tread, sidewall, cushion rubber, and filling rubber.

[0003] Manufacturing Execution System (MES) is a management system for workshop production. In the process from the issuance of work orders to the completion of finished products, the manufacturing execution system plays the role of transmitting information to optimize production activities. In the production process, with the help of real-time and accurate information, MES guides, initiates, responds to, and reports production activities. Make quick responses to changes, reduce production activities without added value, and improve the efficiency of operations and processes.

[0004] A programmable logic controller (PLC) is a type of programmable memory that is used to store programs internally, execute user-oriented instructions such as logical operations, sequence control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input / output.

[0005] At present, the tire manufacturing industry has linked the capabilities of PLC and production control system MES, using the MES system to drive the operation of the entire automated production line and the operation of PLC. Large-scale industrial control systems often use control devices from multiple manufacturers. Because there is no unified specification, each device needs to be driven separately, and barriers appear between the MES and equipment control layers, and information islands exist.

[0006] If traditional networks are used, there will be problems with latency and network bandwidth, resulting in low latency responses during the actual manufacturing process and the inability to process data in real time. Summary of the invention

[0007] The object of the present invention is to provide a tire equipment edge end control system.

[0008] A tire equipment edge control system, which consists of an MES, an MES and edge intermediate library, and a tire equipment edge, including a PLC formula parameter module, a cleaning head signal module, and a PLC production parameter module.

[0009] The MES system and the edge-end intermediate library use the SQL Server database as a data alternation transfer.

[0010] The tire equipment edge end includes a production equipment PLC and an edge end intelligent terminal.

[0011] The production equipment PLC has built-in OPC.

[0012] The PLC recipe parameter module includes a production statistics function, a product parameter trend function and a recipe switching function, wherein:

[0013] Production statistics function, by number of pieces, records total production, qualified production, unqualified production, scrap rate, qualified rate;

[0014] Product parameter trend function, the trend graph is displayed after the front and rear temperature, front and rear width, and front and rear weight per meter parameters are aligned, with 4 display screens on one screen.

[0015] The recipe switching function switches the recipe according to the position of the product tail. When the auxiliary line speeds of the front and rear recipes are inconsistent, the front product maintains the original recipe speed, and the rear product uses the new recipe.

[0016] The cleaning head signal module includes a glue cleaning report function, a head cleaning action feedback flag, and records the start and end time of each glue cleaning action to form a report.

[0017] The PLC production parameter module includes recipe management function, parameter warning function, cross-section graphics function and output data statistics and data packaging function, among which,

[0018] Recipe management function, including four secondary functions: recipe synchronization, recipe data management, recipe switching and distribution, and recipe parameter fine-tuning;

[0019] Parameter warning function, warning of formula parameter exceeding the limit;

[0020] The cross-section graphics function draws cross-section graphics in real time on the interface according to the cross-section scanning parameter coordinates;

[0021] The production data statistics and data packaging function records the data of each product of the tread line and sidewall line after it is produced from the extruder, including the extruder status data, product weight data, width data, length data and placement position. Each tread is made into four data packets, which are divided into four sections according to the proportion of the tread length. The data of each data packet is the average of the parameters to be packaged for each section.

[0022] The recipe synchronization function synchronizes the recipes of MES and the edge intermediate library;

[0023] The formula data management function performs formula query and formula secondary verification;

[0024] The recipe switching and sending function, the recipe is sent to the corresponding address of PLC, and parameter comparison and early warning are performed;

[0025] The formula parameter fine-tuning function sets reasonable steps for the formula parameters according to the upper limit and the upper upper limit. If the parameter adjustment exceeds the upper limit, a reminder will be given. After exceeding the upper limit for a certain period of time, early warning data will be written back to the intermediate library and fed back to MES. The upper limit is not allowed to be exceeded.

[0026] Another object of the present invention is to provide a tire equipment edge end control method, comprising the following steps:

[0027] The S10 MES system sends the recipe to the intermediate library between MES and the edge end;

[0028] S20 MES and the edge-end intermediate library pass the recipe to the production equipment PLC at the edge of the tire equipment;

[0029] The S30 edge intelligent terminal transmits production parameters and action signals to the MES system and the edge intermediate library;

[0030] The S40 MES system integrates and aligns data with the edge-end intermediate library, packages the data and sends it to the MES;

[0031] S50 realizes production statistics, product parameter trends, recipe switching, glue clearing reports, recipe management, parameter warnings, cross-section graphics and production data statistics and data packaging functions through data docking of S10-S40.

[0032] The specific functions are as follows:

[0033] Production statistics: PLC logic programming, determining the formula change logic, product cutting data time and process data of each production section, and logically programming the position sequence of the cross-section stored in the grid after cutting, etc., and recording it in the corresponding address. It is provided to the edge control system through the built-in OPC for further data processing and storage, and provides data support for subsequent data packaging.

[0034] Product parameter trends: PLC logic modification, die head extrusion time and temperature, downhill time and temperature, frequency, front and rear temperatures, front and rear widths, front and rear weight per meter, etc., are provided to the edge control system through the built-in OPC for data trend and presentation, with a total of 4 trend interfaces displayed on one screen.

[0035] Recipe switching: When switching recipes, it is possible that the previous recipe has not been completed. In this case, there will be multiple recipes. The PLC needs to add a new address to cache the old and new recipes. When switching recipes, the recipe is switched according to the position of the product tail. When the auxiliary line speeds of the two recipes are inconsistent, the PLC must ensure that the front-end product maintains the original recipe speed and the back-end product uses the new recipe speed.

[0036] Recipe management includes recipe synchronization, recipe data management, recipe switching and distribution, and recipe parameter fine-tuning.

[0037] Recipe synchronization: The recipe numbers used in equipment production are all sent down through the intermediate library between MES and the edge, and the edge of the equipment stores all synchronization history of the recipe. When synchronizing the recipe, the edge will compare the parameters of the same recipe number in the MES intermediate library based on the synchronized recipe number. If the recipe number has a parameter setting value that changes, the edge will synchronize, and if there is no change, synchronization is not required. The recipe originally stored on the edge is stored in the form of a historical version number. When the recipe is sent down to the PLC, the parameters are always sent down with the latest recipe number parameters.

[0038] Recipe data management: To ensure the consistency of recipe data, the recipe data source is only issued by MES. The edge does not allow the creation, modification, or deletion of recipe parameters. The edge provides the function of viewing recipe data. The recipe data contains various historical versions. For recipe numbers that require secondary process verification, the process personnel are required to check and verify them, and then feedback to MES to update the verification results. Only recipes that pass the secondary verification can have the equipment process parameters of the recipe sent to the PLC. Otherwise, it is not allowed to be sent.

[0039] Recipe switching and distribution. When the recipe is switched, the recipe number of the device's last production is verified with the recipe number of this production, and the difference parameters are verified. If the same recipe number and version number data were used last time, it is determined that there is no difference. If different version numbers of the same recipe are used, the difference parameters are filtered and marked in red or yellow for prompts. The edge end sends the recipe parameters to the device PLC, and the edge end also updates the latest recipe and version number used by the device.

[0040] Recipe parameter fine-tuning: Due to equipment factors, auxiliary fixtures, etc. during the production process, the standard process parameters of the recipe will be fine-tuned. The operator has the authority to directly fine-tune the standard process parameters of the recipe. The standard process parameters of the recipe that can be adjusted for different equipment are not fixed. After being configured by MES, they are sent to the intermediate table. The edge end updates the latest adjustable standard process parameters of the recipe in real time, and automatically increases or decreases the standard process parameters of the recipe according to the configuration. The standard process parameters of the recipe have upper / lower limits and upper / lower limits. When the value of the adjusted standard process parameter of the recipe exceeds the upper / lower limit, the interface pops up a window requiring the operator to fill in a random check code to authenticate that the adjusted parameter exceeds the upper / lower limit. The adjustable range of the standard process parameter of the recipe is not allowed to exceed the upper / lower limit. Parameter warning: Parameter warning is divided into two parts. One part is the warning that can be captured by PLC during the production process of the equipment, such as electrical machinery, and the other part is the warning of the over-limit of the standard process parameters of the recipe. For the PLC warning parameters, the edge end system collects them and writes the parameters to the intermediate library with MES in real time. If the standard parameters of the recipe process exceed the limit, the edge system will determine the exceeded parameters and write the parameters and parameter values ​​that have exceeded the limit for 5 consecutive minutes into the intermediate library with MES.

[0041] Glue cleaning report: The system obtains the glue cleaning action and time, glue cleaning team, glue cleaning action, glue cleaning action start time, and glue cleaning action end time from the PLC and records them. Finally, a local report is formed based on the data records, and the data is written back to the intermediate library with the MES.

[0042] Cross-sectional graphics: Based on the data from the cross-sectional scanning, the cross-sectional graphics are generated on the industrial computer. This has been realized on the cross-sectional scanning equipment. Jiekong provides the logic and algorithm for cross-sectional scanning to generate cross-sectional graphics, opens the data acquisition interface, and re-completes the cross-sectional graphics layer on the system. The addition of this function will extend the overall implementation cycle of the project.

[0043] Production statistics and data packaging: The system collects and stores PLC data through the existing OPC of the extruder, optimizes the method of discretion statistics through the production matching formula and cutting records, ensures that the products produced under a certain formula can be accurately counted, and will not be counted repeatedly with products of other formulas; when cutting sampling function, the current cut product is not included in the production, but the product data before, after or after cutting must be recorded. If the weight of the cut product exceeds 30% of the standard weight, it is 1 product, and if it is less than 30%, it is not counted as a product. This value is adjustable. Regardless of whether the product is qualified or not, it is required to record the product weight, length and width data. For tread line data, each confirmed product has a non-repeating number. The data can be displayed on the system interface, and the system will package and record various information during the production of each section of the formula product, including equipment speed, grille information, current, pressure, auxiliary line speed, weight, width, etc., to prepare the data basis for MES packaging data application. There are 4 data packages for one tread information, which are divided into 4 sections according to the tread interception length. The data of each section is the average value of the real-time data collected in each section.

[0044] The beneficial effects of the present invention are:

[0045] 1. The tire equipment edge control system provided by the present invention connects the formula management, integration and verification between MES and tire production equipment, eliminates the barriers and barriers between MES and equipment control layers, and eliminates the information island phenomenon.

[0046] 2. Realize automatic monitoring of formula parameters, product parameters, and production parameters in the tire production process, ensuring both the timeliness of monitoring and the production quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
