Description

Technical Field

[0001] The invention belongs to the technical field of glass manufacturing, and in particular is a one-key board changing control system based on WINCC. Background Art

[0002] Usually in float glass production, the thickness and width of the glass plate are adjusted mainly by adjusting the speed, angle, travel and pressing depth of the edge drawing machine. The glass produced during the adjustment period is basically waste, so the length of the plate change time directly determines the quality rate of glass production. Since the float glass production line is a super-large inertia system, it usually takes tens of minutes from adjusting the edge drawing machine state to the changed glass coming out of the cold end. The classic control method of input, adjustment, feedback and multiple cycles is obviously not practical.

[0003] In the prior art, the glass plate is modified by obtaining the steps and adjustment data table that need to be adjusted according to the target modification specifications, and the changes of the glass plate after adjustment are observed through small experiments according to the adjustment data table, and the glass plate is modified by multiple experiments. Such a method requires multiple experiments and comparison of the results to finally obtain the modified glass plate. Due to the physical properties of the glass liquid, it is necessary to wait for the glass liquid to stabilize before the adjustment effect can be obtained after adjustment. Therefore, multiple operation steps will make the operation process cumbersome and the modification time long, thereby affecting work efficiency.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0048] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 3 , the first aspect of the present invention provides a one-key board modification control system based on WINCC, including: a data preparation module, a side edge machine adjustment module, a correction fine-tuning module and a database;

[0050] Data preparation module: used to obtain the modified board data and existing data; obtain the adjustment range based on the modified board data and existing data; obtain grouped data based on the adjustment range; construct an initial Excel table, enter the grouped data into the Excel table to obtain an adjusted data table; collect the real-time status data of the glass plate in the tin plate through sensors.

[0051] Exemplarily, the plate modification data in the production plan is extracted from the database, requiring that the glass plate with an original length of 25 mm, width of 10 mm and thickness of 1 mm be modified to a glass plate with a length of 45 mm, width of 30 mm and thickness of 2 mm; the plate modification specifications are input into the historical plate modification data with the same plate modification specifications in the database to obtain the expected speed, expected swing angle, expected left travel distance and expected right travel distance required for each pair of edge drawing machines for the plate modification; in this embodiment, there are 10 pairs of edge drawing machines, and the current speed and current swing angle of each pair of edge drawing machines are still set according to the original plan; the current speed of the first pair of edge drawing machines is 10 meters per hour, and the current swing angle of the clamping device is 1.2 degrees; the expected speed is 12 meters per hour, the expected swing angle is 2.0 degrees, the expected left travel distance is 15 mm, and the expected right travel distance is 12 mm; the current expected speed is subtracted from the current speed to obtain a plate modification speed difference of 2 meters per hour, and the expected swing angle is subtracted from the current swing angle to obtain a plate modification swing angle difference of 0.3 degrees; through the formula TZX=(e |XV| -1)+BJ×2π+|ZJ|+|YJ|The calculated modified board amplitude value is TZX=35.28.

[0052] In this embodiment, the expected threshold is set to 10. The expected threshold is used to obtain the approximate adjustment range of each operation step based on historical data. If too much adjustment is made at one time, it may cause a long adjustment time, and the glass liquid cannot be stable in a flowing state for a long time, resulting in poor effect after adjustment; if too little adjustment is made at one time, it will cause a long time for changing the board; the integer of the board changing amplitude value and the expected threshold entropy value plus 1 is taken to obtain 4 adjustment steps in this embodiment, and the adjustment step number, board changing speed difference, board changing swing angle difference, expected left distance and expected right distance are combined to obtain the adjustment amplitude.

[0053] The adjustment amplitude was divided into four groups. The first group's group adjustment speed was 0.5 meters per hour, the group adjustment swing angle was 0.075 degrees, the group adjustment left line distance was 3.75 millimeters, and the group adjustment right line distance was 3 millimeters. The adjustment amplitudes of the other three groups were the same, and four groups of group data were obtained.

[0054] Construct an initial Excel table, create a sheet for each set of grouped data in order and input the grouped data into it, to obtain an adjustment data table with a total of 4 sheets; and place a position sensor on the tin plate carrying the glass liquid to collect the real-time thickness, real-time length and real-time width of the glass liquid in real time.

[0055] Edge drawing machine adjustment data table: used to input the adjustment data table into WINCC to obtain the adjustment file, and perform real-time adjustment and control of the edge drawing machine based on the adjustment file.

[0056] Exemplarily, an adjustment data table is added to WINCC (process monitoring system), and the delay period is set to 1 second in WINCC; an execution flag is assigned to each group of grouped data, the execution flag of the first group is 1, the execution flag of the second group is 2, the execution flag of the third group is 3, and the execution flag of the fourth group is 4; the grouped data with execution flags are marked as step group data.

[0057] Eight pairs of side pulling machines are needed to complete the adjustment task of the first set of step group data. They are assigned unit numbers 1 to 8 in the order of work, and the remaining two teams of side pulling machines are assigned unit number 0; the starting time of the side pulling machine with unit number 1 is 15 seconds, and the pairing delay of the side pulling machine with unit number 1 is 15 seconds, and the delay period is 1 second. The pairing delay of the side pulling machine with unit number 2 is 16 seconds, and the pairing delay of the side pulling machine with unit number 3 is 17 seconds. The pairing delays of the side pulling machines for the first set of step group data are obtained in sequence.

[0058] Determine whether the average value of the expected speed in the step group data is greater than the current speed. In this embodiment, the average value of the expected speed of the first group of step group data is 10.25 meters per hour, which is greater than the current speed. The current speed is divided by the expected speed average value to obtain a pulling coefficient of 0.97; the delay of the largest unit number for the edge drawing machine is 22 seconds, and the step delay is 47.3 seconds. The WINCC file containing the adjustment data table is marked as an adjustment file.

[0059] It should be noted that the purpose of setting the step delay is that after each step of operation, the glass liquid needs time to make corresponding changes and stabilize, so as to avoid bubbles and cracks in the glass plate due to instability of the glass liquid, and at the same time ensure that the effect of each adjustment step is fully manifested; and the step delay obtained in each group needs to be greater than the delay in the step group data. Equipment adjustment requires a certain amount of time, and it is also necessary to ensure that each change can be adjusted in place, so sufficient space needs to be left for equipment adjustment.

[0060] It should be noted that the stabilization time of the glass liquid depends on factors such as the viscosity, temperature and pulling speed of the glass liquid. However, during the production process, no other additional substances will be added to the glass liquid, so the viscosity of the glass liquid will not change, and the glass liquid will be kept at a constant temperature during the production process. However, if the thickness needs to be changed, the pulling speed of the edge drawing machine needs to be changed, and the pulling speed will affect the stabilization time of the glass liquid. The faster the pulling speed, the longer the stabilization time of the glass liquid, and the slower the pulling speed, the faster the glass liquid can stabilize.

[0061] After starting to change the board, match the step group data with the current execution flag of 1 for adjustment, and judge in real time whether the step delay of the current step group data is 0 after deducting 1. If the step delay of the current step group data is 0 after deducting 1, it means that the current step group data has been adjusted and the outgoing step delay has also been reached. Mark the execution flag of the next group of step group data as 1, and mark the execution flag of the adjusted step group data as 0; if the step delay of the current step group data is not 0 after deducting 1, it means that the current step group data has not been adjusted, and repeat it. The pair delay of the side-pull machine in the current step group data is judged whether it is greater than 0 after the pair delay is reduced by 1. If it is greater than 0, the pair delay is reduced by 1; if the pair delay is not greater than 0 after the pair delay is reduced by 1, there are only two cases where the pair delay is 0 or -1. When the pair delay of the side-pull machine is 0, it means that the corresponding side-pull machine needs to be adjusted. After the adjustment, the pair delay of the side-pull machine is marked as -1; if the pair delay is -1, it means that the side-pull machine has been adjusted, and the corresponding side-pull machine is marked as an adjusted side-pull machine.

[0062] It should be noted that the delay can not only control the adjustment of the edge pulling machine, but also control the edge pulling machine to work in an orderly manner according to the working sequence, thus ensuring the orderliness of the work.

[0063] Correction and fine-tuning module: used to adjust WINCC according to real-time status data and grouping data to obtain correction data, and save the correction data in the database.

[0064] Exemplarily, during the step delay period after each set of step group data is adjusted, the real-time status data collected by the position sensor is compared with the group status data to obtain the adjustment effect. If the group status data does not match the real-time status data, it means that the adjustment effect has not achieved the expected effect. The difference between the group status data and the real-time status data is marked as correction data, and the correction data is input into the database to obtain the correction speed, correction swing angle, correction left distance and correction right distance that need to be adjusted by the edge pulling machine, and the correction plan is integrated to obtain the correction plan. According to the correction plan, the parameters of the edge pulling machine are adjusted, and the edge pulling machine is controlled to be adjusted so that it can achieve the expected effect, and the correction data is recorded in the database; if the same type of correction data appears multiple times, it means that the equipment may be damaged or there is a problem with the equipment parameter settings.

[0065] It should be noted that if the edge drawing machine needs to be adjusted, the step delay of the corresponding step group data needs to be extended to ensure the adjustment effect.

[0066] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.
