Description

Technical Field

[0001] The invention relates to the technical field of glass sheet production, and in particular to a control method for uniformly controlling multiple types of vertical divisions of a flat glass production line. Background Art

[0002] In the intelligent and information-based cold-end production line of flat glass, there is a key link - the longitudinal breaking and splitting process. In this process, the glass is broken longitudinally (in line with the direction of the production line) and then separated for a short distance. With the development of upstream optimized cutting technology, the main line control technology needs to be improved accordingly, and the corresponding longitudinal breaking and splitting control technology also needs to be improved and optimized. With the introduction of various types of longitudinal breaking, the corresponding control methods also need to be improved.

[0003] In practice, it is found that if the control method of the longitudinal breaking and longitudinal division system is changed every time according to the change of longitudinal breaking type, the development of the control program will be cumbersome and error-prone, and repeated changes will take up a long development cycle of the entire line. Moreover, if the old line is cold repaired and rectified, it will incur a large cost to abandon the old equipment. At this time, it is necessary to improve the old equipment architecture and update the control program of the old equipment. Due to on-site reasons, there will be some equipment that cannot be carried out according to the normal process, and further corrections are required in the control, adding restrictions and more combined actions, which increases the difficulty of developing the control method. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0036] See also Figure 1 As shown, the present invention is a control method for uniformly controlling multiple types of vertical divisions of a flat glass production line, comprising:

[0037] S1. The longitudinal breaking and splitting system assigns longitudinal breaking and splitting tasks to different types of glass plates.

[0038] Among them, the longitudinal breaking and dividing system is an embedded system, which is embedded in the production line. The longitudinal breaking and dividing system is composed of a plurality of identical longitudinal breaking units and a plurality of identical longitudinal dividing units, and each longitudinal breaking unit is a group with the corresponding longitudinal dividing unit. The longitudinal breaking unit is used to perform tracking according to the arranged longitudinal breaking tasks, and to count the formula according to the type of glass plate. There are three types of longitudinal dividing actions of the longitudinal dividing unit, namely the first longitudinal dividing action, the second longitudinal dividing action, and the third longitudinal dividing action, and each longitudinal dividing action has a different angle. The first longitudinal dividing action is to separate the glass plate to the left at a preset angle and a preset distance, the second longitudinal dividing action is to separate the glass plate to the right at a preset angle and a preset distance, and the third longitudinal dividing action is to make the glass plate pass through the horizontal position without changing.

[0039] The vertical tasks are pre-set tasks. The pre-set tasks are to set the automatic control recipes in advance for different types of glass plates. Based on the movement of different glass plates, the glass information of the main line control system is connected to perform targeted actions.

[0040] The inventors found that the traditional control method is to fix the control process within the longitudinal breaking and dividing system. Each production line has a fixed plan, and the entire set of combined processes can be determined after production is started.

[0041] In this embodiment, the process control can be opened to the human-computer interaction interface, and the user can assign longitudinal breaking or longitudinal division tasks to the control system, split the single longitudinal breaking or longitudinal division links, and then distribute them according to actual needs to combine the required control process to avoid the fixation of the control process.

[0042] Take the production of three-point boards with two groups of longitudinal bending as an example:

[0043] Define four longitudinal breaking units:

[0044] The left side of number one is A, and the right side of number one is a.

[0045] B is on the left side of number two, and b is on the right side of number two.

[0046] There are two cuts on the three-point board:

[0047] Define the No. 1 cut mark as M

[0048] Define the cut mark No. 2 as N

[0049] According to the site, the required process is:

[0050] AM, BN (remove the 1st cut on the left side of the top three-point board for No. 1, and remove the 2nd cut on the left side of the top three-point board for No. 2)

[0051] AN, BM (No. 1 removes the No. 2 cut on the top three-point board on the left side, and No. 2 removes the No. 1 cut on the top three-point board on the left side.

[0052] And so on, there are aM, bN, or aN, bM, or AM, bN, or aM, BN.

[0053] In the prior art, the above-mentioned three-part board process is relatively complicated without nesting (i.e., producing two or more different types of board types at the same time). It is time-consuming and labor-intensive to develop all of them, and the workload is huge and prone to errors. If each site is developed once specifically, it will not only take up the debugging cycle, but also be difficult to expand and change.

[0054] In this embodiment, the No. 1 knife mark is opened with A or a, and the No. 2 knife mark is opened with B or b. The user can choose the arrangement and combination to meet the production needs.

[0055] S2. After the longitudinal breaking and dividing system detects that the glass sheet has entered the process area, it interacts with the main line tracking system to obtain online glass information.

[0056] S3. Analyze whether the online glass matches the assigned longitudinal bending and longitudinal splitting tasks, and read the knife mark position of the glass plate to determine whether the knife mark position is within the travel range.

[0057] S4, convert the knife mark position into the travel data of the transverse movement motor, and activate the cylinder action authority in the longitudinal bending and dividing system.

[0058] S5. Adjust the servo motor to make the glass reach the preset position, the cylinder lifts up, and falls down after the lifting time is reached.

[0059] S6. Check whether the servo motor and the cylinder have completed the action, and feed back the test results to the upper monitoring link.

[0060] In this application, the specific operations are as follows:

[0061] 1. Break the one-point board vertically

[0062] A one-piece large board has no middle knife marks and does not require longitudinal bending action, so there is no need to assign tasks. After detecting that it is a one-piece large board, the longitudinal bending maintains the original position and the cylinder action is not activated.

[0063] 2. Please refer to Figure 2-Figure 3 As shown, for the two-point board longitudinal break

[0064] There are 6 configurations for the two-part board vertical breaking task, as follows:

[0065] (1) "Not started", that is, when the two-piece glass is produced in this longitudinal bending area, the longitudinal top does not move and the transverse movement does not move.

[0066] (2) "Only the knife mark on the left side", that is, when producing two-piece glass, and the glass is a biased-split glass, and the left side of the glass is smaller and the right side is wider, at this time, the longitudinal breaking device moves horizontally from the previous working state to the position below the knife mark, and when the glass is completely inserted, it is longitudinally pushed up.

[0067] (3) "Left-biased and center-split", that is, move horizontally to the standard equally divided board, and the board type with a smaller width on the left and a larger width on the right (the knife mark is on the left), and then wait for an opportunity to lift it up.

[0068] (4) "All two-point boards" means that when all the two-point boards come, they are moved horizontally to the corresponding middle knife marks, waiting for an opportunity to lift them up.

[0069] (5) "Right-biased and center-split", which is the opposite of left-biased and center-split, the standard equally divided board, and the board type with a larger width on the left and a smaller width on the right (the knife mark is on the right), and then wait for an opportunity to lift it up.

[0070] (6) "Only right-biased knife mark" is the opposite of only left-biased knife mark. When the board is detected to be a two-part board, and the width of the left side is larger than that of the right side (the knife mark is on the right side), the longitudinal breaking device moves horizontally to the knife mark position and waits for an opportunity to lift it up.

[0071] 3. Please refer to Figure 4-Figure 5 As shown, for the three-point board vertical break

[0072] There are 3 configurations for the three-point board vertical breaking task:

[0073] (1) “Not started”: when the three-panel glass is produced in this longitudinal bending area, the longitudinal top does not move and the transverse movement does not move.

[0074] (2) “No. 1 knife mark”: when the three-piece glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 1 knife mark position, and then waits for an opportunity to lift it up.

[0075] (3) “No. 2 knife mark”: when the three-piece glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 2 knife mark position, and then waits for an opportunity to lift it up.

[0076] 4. Please refer to Figure 6-Figure 7 As shown, for the longitudinal bending of the four-point board

[0077] There are 4 types of configurations for the four-part board longitudinal breaking task:

[0078] (1) “Not Started”: When the production of quarter-panel glass comes to this longitudinal bending area, the longitudinal top does not move and the transverse movement does not move.

[0079] (2) “No. 1 knife mark”: when the quartered glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 1 knife mark position, and then waits for an opportunity to lift it up.

[0080] (3) “No. 2 knife mark”: when the production of quartered glass comes to this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 2 knife mark position, and then waits for an opportunity to lift it up.

[0081] (4) “No. 3 knife mark”: when the quartered glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 3 knife mark position, and then waits for an opportunity to lift it up.

[0082] 5. Please refer to Figure 8-Figure 9 As shown, for the five-point board vertical break

[0083] There are 5 configurations for the five-point board vertical breaking task:

[0084] (1) "Not started": when the five-point plate glass is produced in this longitudinal bending area, the longitudinal top does not move and the horizontal movement does not move.

[0085] (2) “No. 1 knife mark”: when the five-piece glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 1 knife mark position, and then waits for an opportunity to lift it up.

[0086] (3) “No. 2 knife mark”: when the five-piece glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 2 knife mark position, and then waits for an opportunity to lift it up.

[0087] (4) “No. 3 knife mark”: when the five-piece glass is produced in this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 3 knife mark position, and then waits for an opportunity to lift it up.

[0088] (5) "No. 4 knife mark": when the five-piece glass is produced and comes to this longitudinal breaking area, the system controls the longitudinal breaking device to move horizontally to the No. 4 knife mark position, and then waits for an opportunity to lift it up.

[0089] 6. Control of vertical division

[0090] There are three types of vertical division actions, namely three angles, as follows:

[0091] “\”: Move the glass a short distance to the left. The more the number, the greater the horizontal distance.

[0092] “ / ”: Move the glass a short distance to the right. The more the number, the greater the horizontal distance.

[0093] “—”: The glass moves along without changing its lateral position.

[0094] See also Fig.10 As shown, the vertical division direction and quantity suitable for production can be selected in the human-computer interaction interface. The present invention can be "pre-set" for vertical division, that is, the automatic control formula is set in advance for different boards. When different boards arrive, the system connects the glass information of the main line control system and performs intelligent targeted actions.

[0095] For example, when it comes to a two-splitting board, the vertical splits of No. 1, 1, 2, 3, and 4 from the left will perform the "\" left-biased action, and the vertical splits of No. 5, 6, 7, and 8 from the left will perform the " / " right-biased action, and the following vertical splits of No. 2 and No. 3 will return to the initial "—" state.

[0096] The same operation can be used to set the pre-allocated recipe to the vertical division units of the three-part board, four-part board, and five-part board. By coordinating them as a whole, intelligent multi-order production can be completed.

[0097] For the automatic lateral tracking control of longitudinal breaking, the traditional approach is to make fixed control according to the automation control requirements put forward by the process designers, that is, how the system will act is first written inside the PLC, and then executed according to the planned actions. However, due to the increasing demand for automation, the number of production arrangements and combinations, and the actual requirements for longitudinal breaking effects, process designers are unable to provide more optimized action plans, and the same is true for longitudinal breaking.

[0098] The present invention can effectively solve the inconvenience of use and programming caused by the fixed thinking of traditional longitudinal breaking and dividing. Each longitudinal breaking is divided into a single action unit, and the tracking task is performed in real time according to the task assigned by the user each time. For all types of boards, the formula is counted, and the task can be fully intelligently and automatically executed, so that the tracking of the knife mark is carried out when it should be tracked, and the tracking of the knife mark that should not be tracked is not carried out.

[0099] It is understandable that when producing a one-piece large board, it does not need to be separated, so there is no need for pre-allocation. When the system detects that it is a one-piece large board, it controls all longitudinal divisions to return to the initial "—" horizontal state.

[0100] Correspondingly, the method of vertical division is consistent with that of vertical breaking, that is, the automated action mode of vertical division control is decomposed and opened up for user customization.

[0101] In the present application, the control method for uniformly controlling various types of longitudinal splitting of a flat glass production line can effectively solve the problem of developing a special type of longitudinal breaking and splitting system, that is, a certain longitudinal breaking unit has limitations, such as: due to the influence of the roller base on the production line, the left side longitudinal break of No. 2 is moved horizontally to the position below the No. 1 knife mark of the 4-split board, and the traditional control method requires redevelopment of the control process of the No. 2 longitudinal break. If the present control method is used, it is sufficient to delete the No. 1 knife mark task of the left side longitudinal break of the 4-split board. As a unified control, it is more convenient.

[0102] In addition, this control method can effectively solve the problem of upgrading the control of old longitudinal breaking and dividing systems. There is no need to redevelop, and the upgraded equipment can complete the task in the task options. It not only reduces the system development cycle, but also simplifies the control process, so that a single set of programs can adapt to more longitudinal breaking and dividing processes. It only needs to turn off the longitudinal breaking and dividing equipment that is not actually needed on the human-computer interaction interface.

[0103] In addition, this control method can effectively solve the problem of targeted task allocation for users. For example, the No. 1 longitudinal bend of the top two-part board has a better effect, and the No. 2 knife mark of the top three-part board has a better effect. At this time, there is no need to change the original control process and it can be freely matched.

[0104] This application is based on the disassembly of longitudinal breaking and dividing action units, and the method of openly allocating tasks facilitates the continued expansion of production board types.

[0105] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the claims of the present invention.
