[0016] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the system modules of a roller separator correction control system and method in an embodiment of this application. Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example: like Figure 1 The purpose of this invention is to provide a method for corrective control of a roller separator.

[0020] Step S1: Obtain past factory operation data, analyze the past factory operation data to obtain past coil material demand and past roll separator operation data, and generate an operation mapping specification table based on the mapping relationship between past coil material demand and roll separator operation data.

[0021] Furthermore, the method of analyzing past factory operation data to obtain past roll material demand types and past roll sorting machine operation data, and generating an operation mapping specification table based on the mapping relationship between past roll material demand and roll sorting machine operation data includes matching past roll material demand and roll sorting machine operation data one by one to form a basic correspondence.

[0022] Based on the type of coil material, the demand for coil materials and the past operating data of the roll separator are classified and divided into several first coil material demand category identifiers and first past operating data.

[0023] Based on different size specifications, the demand for roll materials and the past operating data of the roll sorting machine are classified into several second roll material demand category identifiers and second past operating data.

[0024] The types and dimensions of the roll material are fitted to obtain fitted values.

[0025] Based on the fitted values, several first roll material demand category identifiers and several second roll material demand category identifiers are sorted and merged to obtain several conditional data groups, which are defined as the original image set.

[0026] Several sets of first and second past running data are filtered and integrated, and some duplicate data are removed to obtain several result data groups. These result data groups are defined as image sets.

[0027] Based on the mapping relationship between the original image set and the image set, a runtime mapping specification table is generated.

[0028] Understandably, fitting the types and sizes of rolled materials can narrow the data range, simplify the massive amount of data, and reduce the computational load of the system.

[0029] The method for fitting the types and dimensions of roll materials to obtain fitted values ​​includes collecting the mechanical properties of different types of roll materials and the dimensions involved in the roll materials. The mechanical properties include strength, stiffness, and stability.

[0030] The mechanical properties and dimensional specifications of any two types of roll materials are fitted to obtain the fitted values.

[0031] A standard fitting value is preset, and several first roll material demand category identifiers and several second roll material demand category identifiers that do not exceed the fitting value are merged to obtain several conditional data groups.

[0032] The formula for fitting calculation is as follows: ; in, The first conversion coefficient, This is the second conversion coefficient. For the strength of the first roll, For the strength of the second roll, For the first roll of material stiffness, For the stiffness of the second roll, For the stability of the first roll, For the stability of the second roll, The thickness of the first roll is... This refers to the thickness of the second roll.

[0033] It's important to understand that the mechanical properties to consider when manufacturing roll materials include strength, stiffness, and stability. Strength refers to the roll material's ability to withstand a specified load without failure; stiffness indicates that the roll material needs sufficient resistance to deformation; and stability means that the roll material should have sufficient ability to maintain its original equilibrium shape. Therefore, roll materials are categorized based on their strength, stiffness, and stability.

[0034] Step S2: Input the roll material task requirements, and find the initial roll separator operation data that matches the roll material task requirements in the operation mapping specification table according to the operation parameter mapping relationship. Based on the initial roll separator operation data, make preliminary settings for the roll separator.

[0035] Based on the mapping relationship of operating parameters, the method for finding the initial roll separator operating data that matches the roll material task requirements in the operating mapping specification table includes obtaining the roll material task requirement information under real-time conditions.

[0036] The real-time roll material demand category identifier is obtained by analyzing the roll material task demand information from two aspects: the type of roll material and the size specification.

[0037] The current real-time roll material demand category identifier is determined in the running mapping specification table, and the corresponding result data group is obtained in the image set according to the real-time roll material demand category identifier and its mapping relationship.

[0038] Understandably, by using the real-time roll material demand category identifier and its mapping relationship, the initial roll sorting machine operation data can be quickly and accurately obtained from the operation mapping specification table, thereby improving the system's operating efficiency.

[0039] Step S3: Determine the status acquisition devices set at different position nodes of the roller separator, and collect the operating status data of each status acquisition device in real time.

[0040] It is important to understand that the status acquisition device is used to observe the position and edge flatness of the roll material, and to analyze the edge data and edge wrinkles of the roll material to obtain data.

[0041] Step S4: Analyze the operating status data of different state acquisition devices, determine the first attitude data of different rollers of the roller separator, correct the first attitude data of different rollers to obtain the second attitude data, and combine the corrected second attitude data with the uncorrected first attitude data to generate the corrected operating data of the roller separator.

[0042] The method for analyzing the operating status data of different state acquisition devices, determining the first attitude data of different rollers of the roller separator, and correcting the first attitude data of different rollers includes presetting the standard roller separator operating timeline and different time scale limits under different roll material processing conditions.

[0043] The standard roller separator running timeline is copied to obtain several standard roller separator running timeline sub-lines.

[0044] Several standard roller separator running time sub-lines are divided into several time scale sub-lines according to different time scale constraints. The analysis period of the first attitude data of the roller is determined based on each time scale sub-line.

[0045] If the number of anomalies in the first attitude data corresponding to the time scale sub-line is less than the preset value, then the time scale sub-line will be expanded for analysis and correction.

[0046] Understandably, different time scales represent the analysis cycle of the first attitude data of the roller. If enough anomalies are detected within a shorter cycle, it means that the current time scale is just right as the detection cycle and can be corrected.

[0047] The method of analyzing the operating status data of different state acquisition devices, determining the first posture data of different rollers of the roll separator, and correcting the first posture data of different rollers also includes acquiring the operating status data of each state acquisition device, analyzing the operating status data, obtaining the current edge position information and the current edge wrinkle information of the roll, and calculating the centerline position information of the roll based on the current edge position information of the roll.

[0048] There is a pre-set table of standard centerline position information for different roll materials. The difference between the real-time centerline position information of the roll material at the current time scale and the standard centerline position information of the same roll material is calculated to obtain the centerline offset value. The roller displacement is corrected according to the centerline offset value.

[0049] The current information on edge wrinkles of the roll material is rated, and the roller angle is corrected based on the rating results.

[0050] It is understandable that the roll material may experience positional deviation during the production process, a situation known as misalignment. In addition, if wrinkles appear at the edge of the roll material, they can be addressed by adjusting the parameters of the rollers. Therefore, this application corrects the roller separator based on the centerline position of the roll material and the condition of edge wrinkles.

[0051] The centerline offset value is obtained by calculating the difference between the real-time centerline position information of the current roll material and the standard centerline position information of the same roll material. The specific method for correcting the roller displacement based on the centerline offset value is as follows: Obtain the current edge position information of the roll material and record the edge position information as follows: and .

[0052] according to and The current position of the centerline is calculated. The The calculation method is as follows: .

[0053] By calculating the current centerline position information The difference between the current centerline position and the standard centerline position information, along with the positive and negative values, yields the current centerline offset value.

[0054] If the centerline offset value is positive, the roller displacement is adjusted in the positive direction, with the value corresponding to the current centerline offset value. If the centerline offset value is negative, the roller displacement is adjusted in the reverse direction, with the value corresponding to the current centerline offset value.

[0055] The specific method for rating the current edge wrinkles of the roll material and correcting the roller angle based on the rating results includes obtaining the current edge wrinkle information of the roll material and judging the current edge wrinkle direction and degree of edge wrinkles of the roll material.

[0056] The rating result is positive or negative based on the direction of the edge wrinkles of the roll material, and the rating value is defined based on the degree of edge wrinkles of the roll material, thus obtaining the rating value.

[0057] An angle conversion factor is configured for the rating value to obtain the roller angle correction value, and the roller angle is corrected according to the roller angle correction value.

[0058] In addition, a method for correcting deviations in a roller separator also includes: evaluating the anomalies of the current timescale sub-line and determining the magnification factor of the timescale sub-line based on the anomaly evaluation, wherein the higher the anomaly evaluation value, the lower the magnification factor.

[0059] The number of times the centerline position of the roll material and the edge wrinkles of the roll material are generated on a defined time scale is defined as the number of anomalies.

[0060] Anomaly evaluation is performed on the sub-line at the current time scale based on the number of anomalies, the offset of the centerline position, and the wrinkling of the roll edge.

[0061] The formula for anomaly evaluation is as follows: .

[0062] in, This is an abnormal evaluation value. For the number of abnormal occurrences, The first conversion coefficient, This is the second conversion coefficient. This provides the midline position information corresponding to the i-th anomaly. This provides the standard midline position information corresponding to the i-th anomaly. This represents the rating result for the edge wrinkles of the roll material corresponding to the i-th anomaly.

[0063] Understandably, the amplification factor needs to be determined during the amplification correction process. The higher the anomaly evaluation value, the closer the time scale is to the standard value, and therefore the lower the amplification factor.

[0064] Step S5: Record the correction operation data of the roller separator and record the correction operation data of the roller separator into the operation mapping specification table.

[0065] This application discloses a method for correcting the deviation of a roller separator, which has the following advantages in the operation of roller separator deviation correction: 1. Based on the mapping relationship between past demand for rolled materials and past operation data of roll separators, this application generates an operation mapping specification table and fits the data, thereby reducing the data volume and improving the efficiency of confirming the initial operation data of the roll separator.

[0066] 2. This application is equipped with a status acquisition device to detect and acquire the position and edge wrinkles of the roll material, which facilitates the real-time correction of the first posture data of different rollers from the aspects of angle and displacement to obtain the second posture data, thus greatly improving the accuracy of the roller separator in terms of correction.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
