Description

Technical Field

[0001] The present application relates to the technical field of steel production, and in particular to a shearing control method, system, equipment and storage medium based on a cut-to-length shear. Background Art

[0002] Among the key links of the wide and thick plate production line, the segmented cut-to-length of the finished medium plate is of vital importance. It refers to a cutting process in the finishing area of ​​the wide and thick plate production line to accurately divide the finished medium plate according to the established length or size requirements. It is usually carried out in the final stage of the wide and thick plate production line to ensure that the size and quality of the product meet customer needs or production standards. The cut-to-length shear, as the core equipment in this link, is a large-scale equipment that integrates precision machinery and complex control systems. It has many internal interlocking mechanisms and extremely stringent requirements on control accuracy. In related technologies, the degree of automation of the production line is generally low, and the length is usually determined by manual marking. That is, when the steel plate is fed into the cut-to-length shear from the input roller, the length of the cut needs to be determined manually, and then it is cut by the cut-to-length shear and sent out by the output roller.

[0003] However, manual marking is not only labor-intensive, but also prone to human error and difficult to guarantee accuracy, which undoubtedly brings instability to the quality of finished steel plates. At the same time, this inefficient production method also seriously restricts the improvement of production line efficiency, putting enterprises at a disadvantage in market competition. Therefore, how to achieve efficient and accurate automated shearing is a problem that needs to be solved urgently. Summary of the invention

[0029] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the form, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0031] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0032] It should be noted that cut-to-length shears are widely used in wide and thick plate production lines to cut the rolled wide and thick plates into specific lengths that meet customer needs. The shearing process includes: first, the steel plate is fed into the cutting edge by the input roller, and the length size needs to be determined manually at this time; second, the pressing plate is pressed, that is, when the steel plate is fed to the predetermined position, the pressing plate device will press the steel plate to prevent the steel plate from moving during the shearing process; third, start shearing, use the shear blade of the cut-to-length shear to shear the steel plate horizontally, and after the pressing plate presses the steel plate, the swing roller descends to form a certain space so that the sheared steel plate can fall smoothly; fourth, the shearing is completed. When the shearing is completed, the shear blade returns to its position and waits for the next shearing. At the same time, the swing roller rises and the steel plate is sent out by the output roller.

[0033] Basic control system, process control system and production control system are different levels of control systems in the field of industrial automation, namely L1, L2 and L3. Among them, the basic control system is also called primary automation control or field-level control system, which mainly realizes direct monitoring and control of production equipment through programmable logic controller (PLC), and is usually directly connected to field equipment (such as cut-to-length shears, sensors, etc.) to ensure that the equipment operates according to the predetermined procedures and parameters; the process control system is also called secondary automation control or process-level control system, which is located above the basic control system. Its main functions include setting and adjusting the control parameters of each production equipment according to the production plan issued by the superior (L3) system, and tracking the flow of materials in the production process to ensure the smoothness of the production process. It also provides a human-machine interface (HMI) to facilitate operators to monitor and manage the production process; the production control system is also called the third-level automation control or production management level control system, which is at the highest level and is mainly responsible for the formulation and issuance of production plans, the scheduling of production resources, the monitoring of production processes, and the analysis of production data.

[0034] In addition, the types of finished boards generated mainly include full-length and fixed-length. The full-length length is a range of lengths, and all boards within this range can be cut and inspected before delivery; the fixed-length length is a fixed value, and cutting, quality inspection and delivery must be strictly carried out in accordance with this length.

[0035] See also Figure 1 , is a flow chart of a shearing control method based on a cut-to-length shear according to an exemplary embodiment of the present application. Figure 1 As shown, in an exemplary embodiment, the shearing control method based on the cut-to-length shear includes at least steps S110 to S140, which are described in detail as follows:

[0036] Step S110, obtaining a shearing plan and a target steel plate to be sheared, wherein the shearing plan includes the type and set length of the finished plate to be produced.

[0037] In one embodiment of the present application, at least the actual size and shearing plan of the target steel plate are obtained, and the shearing plan may also include the number of finished plates to be sheared from the target steel plate.

[0038] In one embodiment of the present application, the shearing plan is determined by a production control system, and the actual size of the target steel plate can be directly obtained by a process control system.

[0039] In one embodiment of the present application, if the shearing plan also includes a sampling position, the finished plate needs to be sampled and tested, and the process control system determines the sampling shearing length according to the sampling position, and sends it to the basic control system for execution, so as to reserve the shearing length when the pre-cutting process is sheared in sections, that is, before the cut-to-length shearing, the target steel plate is reserved with the sampling shearing length. In addition, the process control system can display the target steel plate to be sheared through the HMI (Human-Machine Interface) screen, and distinguish the target steel plates that need to be sampled and those that do not need to be sampled by color.

[0040] Step S120, matching the preset cutting rules according to the type of the finished board to determine the cutting rules that match the finished board, the preset cutting rules include a mapping relationship between the cutting rules and the type of the finished board, and the cutting rules are used to correct the set length of the finished board.

[0041] In one embodiment of the present application, the set length of the preset configuration in the shearing plan is usually a fixed length. Based on this, shearing cannot be applied to all situations and is likely to cause loss of steel plates. Therefore, different shearing rules are executed for different types of finished plates to automatically correct the set length of the preset configuration in the shearing plan according to the shearing rules. While meeting the actual production needs of the finished plates, production losses are reduced, thereby avoiding waste of steel plates and reducing the production costs of the enterprise.

[0042] In step S120, the shearing rules for different types of finished plates include: if the type of the finished plate is a through-length plate, when the effective shearing length is less than the set length and the effective shearing length is within the length range specified by the through-length plate, the effective shearing length is used as the set length, and the effective shearing length is the maximum length that the target steel plate can currently be sheared; if the type of the finished plate is a fixed length, when the effective shearing length is less than the set length, the effective shearing length is used as the set length, and the shearing plan of the finished plate is reallocated. In this way, the loss of steel plates is effectively reduced, especially the yield rate of through-length steel plates. In addition, when the shearing plan cannot be met through the shearing rules, that is, when the effective shearing length is less than the set length, the shearing order of the finished plate needs to be reallocated later. The shearing order is for the finished plates that meet the order specifications and quantity at the time of delivery to meet the actual production quantity of the finished plates, further improve the automation of shearing, and have high production efficiency.

[0043] In one embodiment of the present application, the actual size of the target steel plate includes data of multiple dimensions such as length, width, and height, so the actual length of the target steel plate can be determined. The actual length of the effective shearing length of the target steel plate minus the length of the head and tail to be sheared is the value. If the target steel plate reserves a shearing length for sampling, the value also needs to be minus the shearing length of the sampling to obtain the effective shearing length. The length of the head and tail to be sheared can be included in the shearing plan.

[0044] In one embodiment of the present application, the type of the finished plate is a through ruler, the set length is 12000mm (millimeter), and the specified length range is 9000mm to 12000mm. If the effective shearing length of the target steel plate is 10000mm, the set length is corrected from 12000mm to 10000mm. In addition, although the situation rarely occurs, if the type of the finished plate is a through ruler, and the effective shearing length of the target steel plate is less than the minimum value in the specified length range, the effective shearing length is used as the set length, and the finished plate sheared out is judged to be unqualified, and the shearing plan of the finished plate is reallocated.

[0045] Step S130, the set length is corrected in combination with the shearing rule and the target steel plate to determine the target set length of the finished plate.

[0046] In one embodiment of the present application, if the effective shearing length of the target steel plate can meet the set length, that is, the effective shearing length can be greater than or equal to the set length, the set length will not be corrected; if the effective shearing length of the target steel plate does not meet the set length, the set length will be corrected according to the shearing rules.

[0047] In step S130, the number of finished plates sheared from the target steel plate is obtained according to the shearing plan; if the number of finished plates is multiple, the finished plate sheared last is used as the target finished plate; the set length of the target finished plate is corrected based on the shearing rule, and the target set length of the target finished plate is determined; wherein, if the type of the target finished plate is fixed length, and the target set length of the target finished plate is less than the set length, it is determined that the target finished plate that is subsequently sheared is unqualified, and the shearing order needs to be reallocated based on the target finished plate.

[0048] In one embodiment of the present application, taking the number of finished plates that can be cut as N as an example, if the target steel plate is a single-size, N is 1, and the set length of the finished plate is directly corrected according to the cutting rule; if the target steel plate is a multiple-size, N is an integer greater than 1, and priority is given to not changing the set length of the finished plates cut in the first N-1 blocks, and then the set length of the finished plate cut by the Nth block is corrected based on the cutting rule.

[0049] Step S140, controlling the cut-to-length shear to shear the target steel plate based on the target set length to obtain a finished plate.

[0050] In one embodiment of the present application, when the target steel plate reaches the area of ​​the cut-to-length shear input roller, the target steel plate is centered, the steel is automatically fed and the length measuring roller is pressed down, the head is cut off and shearing is started according to the target set length to obtain a finished plate, and the actual length of the finished plate after shearing is measured by a cut-to-length machine. Finally, the cut-to-length shear completes the shearing action and transports the sheared finished plate to the next process through the output roller. Among them, the area of ​​the cut-to-length shear input roller is located at the entrance of the cut-to-length shear equipment, which is the conveying channel for the target steel plate before entering the cut-to-length shear for shearing, and the output roller is located at the exit of the cut-to-length shear equipment, which is the conveying channel for the finished plate after shearing. In addition, the above operations can be directly executed by the basic control system, and then the process control system automatically generates a unique steel plate number for tracking the finished plate according to the actual length of the received finished plate, so as to facilitate the subsequent tracking of the sheared finished plate.

[0051] In one embodiment of the present application, if the type of the finished board is fixed length and the actual length measured is not equal to the set length, the finished board is judged to be unqualified; if the type of the finished board is through-length and the actual length measured is not within the prescribed length range, the finished board is judged to be unqualified. In addition, the finished boards that are truly qualified need to be reassigned to the cutting order.

[0052] See also Figure 2 , for this application, the automated shearing based on cut-to-length shears in this application can be realized by the production control system (L1 system), the process control system (L2 system) and the basic control system (L3 system). Among them, the L3 system can exchange and integrate data with multiple L2 systems and external systems based on TCP / IP (Transmission Control Protocol / Internet Protocol); the L2 system can exchange data with multiple L1 systems based on TCP / IP, and has a high degree of integration and scalability; the L1 system is usually directly connected to field equipment (such as sensors, cut-to-length shears, etc.).

[0053] In one embodiment of the present application, the shearing plan of different production lines is determined by the production control system; then it is sent to the corresponding one or more process control systems, and the process control system responds to the shearing plan, executes steps S120 and S130, and then generates a one-to-one corresponding shearing instruction based on the target set length of the finished plate under each production line, and sends it to the basic control system corresponding to each production line; the basic control system responds to the corresponding shearing instruction and executes step S140, that is, calling the cut-to-length shear on the corresponding production line to shear the target steel plate of the production line to obtain the finished plate. In this way, through the coordination and cooperation between the three systems, a set of cut-to-length shearing automated shearing solutions is formed, which greatly improves the shearing efficiency of the production line and the stability of the quality of the finished plate.

[0054] See also Figure 3 , is a schematic diagram of a shearing process shown in an exemplary embodiment of the present application. Figure 3 As shown, the overall process of shearing includes: first, when the head of the target steel plate enters the entrance roller of the cut-to-length shearing area, the calculation of the target length of the finished plate by the L2 system is triggered, and the shearing plan issued by the L3 system is read, and then the type of the shearing mother plate (target steel plate) is determined to be single-length or multi-length, and the number of finished plates that can be generated by the shearing target is determined. The target set length of each finished plate is calculated according to the preset shearing rules, and the shearing setting is formed and sent to the L1 system. The L1 system controls the cut-to-length shear to automatically complete the shearing according to the shearing setting, and uploads the shearing performance (actual length) of the finished plate to the L2 system to generate a sub-plate impression, and the L2 system then uploads the shearing performance to the L3 system. In addition, the L2 system can also calculate the shearing setting in advance, and then send it to the L1 system when the head of the target steel plate enters the entrance roller of the cut-to-length shearing area. After the shearing of a single finished plate is completed, the process control system updates the shearing data of the sub-plate (including the actual length) and the mother plate (including the remaining actual length) to the corresponding database for easy data management.

[0055] In one embodiment of the present application, when the basic control system detects that the target steel plate enters the entrance roller of the cut-to-length shear, the target steel plate is tracked by the calculation method of the velocity integral, and is fed back to the process control system to generate a motherboard tracking impression on the HMI screen. At the same time, the process control system sends the target set length of the finished plate to the basic control system according to the shearing plan of the production control system. Among them, the velocity integral is related to time and is used to describe the displacement or position change of an object. The velocity is the derivative of the displacement or position with respect to time. Therefore, by integrating the velocity over time, the displacement or position of the object can be obtained.

[0056] See also Figures 4 to 6 , are schematic diagrams of shearing plan, setting and process respectively shown in an exemplary embodiment of the present application. Figure 4From the shearing plan displayed on the HMI screen shown, it can be seen that the type of finished board to be produced is through-length, the specified length range is 9000mm to 12000mm, and the set length is 12000mm. Figure 5 The shearing settings displayed on the HMI screen include: the length of the cutting head (i.e. the length of the target steel plate head to be cut) is 100mm, the length of the cutting tail (i.e. the length of the target steel plate tail to be cut) is 201,2832mm, and the set length of the middle segmented shearing (i.e. the set length of the finished plate) is 12000mm.

[0057] Combination Figure 4 and Figure 5 ,accomplish Figure 6 The shearing process of the target steel plate is as follows: Step 1, when Figure 6 When the target steel plate with the plate number of 12409262B11001 reaches the input roller of the cut-to-length shear, the process control system will read the shearing plan from the production control system and display it on the HMI interface synchronously, that is, Figure 4 Step 2: Calculate the shear setting according to the shear plan and the actual size of the target steel plate, including the target set length of the finished plate, and display it on the HMI interface, i.e. Figure 5 ; Step three, control the magnetic suction device through the basic control system to complete the roller edge action of the target steel plate 12409262B11001, receive the shearing setting, and start the steel feeding and shearing action; Step four, if the target steel plate is distinguished as a sampling plate according to the color and sampling is required, the sampling operation is completed according to the sampling position mark in the shearing plan; Step five, after the sampling is completed, the shearing of the finished plate begins. For each finished plate sheared, the basic control system will return the shearing performance corresponding to the finished plate. The shearing performance represents the completion of the shearing of the finished plate, which includes the actual length of the sheared finished plate to the process control system, so that the process control system generates a tracking impression of the finished plate according to the shearing performance, and stores the shearing performance in the database, wherein the HMI screen of the shearing process of the two finished plates 12409262B1100A and 12409262B1100B is displayed as follows Figure 6 As shown; Step 6, the cut-to-length shear completes the shearing action, and the output roller of the cut-to-length shear automatically transports the finished board to the next process; Step 7, the process control system uploads the shearing results of the finished board to the production control system.

[0058] After step S140, the sheared finished plate is transmitted by a roller; the position of the finished plate on the roller is tracked based on the speed integral, and the sub-plate tracking impression of each finished plate is determined; the mother plate tracking impression is updated according to the sub-plate tracking impression, and the mother plate tracking impression is obtained by tracking the position of the target steel plate.

[0059] In one embodiment of the present application, the position of the steel plate is tracked to obtain tracking information including the steel plate number, position and actual length of the steel plate, and an intuitive picture of the position, state and path of the steel plate is established in the HMI screen based on the tracking information, that is, the tracking information is intuitively displayed in the HMI screen in text form and / or graphical form, and is used as a tracking impression. In the present application, the tracking impression of the target steel plate is referred to as the mother plate tracking impression, and the tracking impression of the finished plate is referred to as the daughter plate tracking impression.

[0060] In one embodiment of the present application, during the shearing process of the target steel plate, the position and size of each finished plate sheared will be recorded, and the tracking impression of the sub-plate will be determined. The shearing of the finished plate will affect the position and size of the target steel plate. Therefore, the tracking impression of the target steel plate can be updated according to the tracking impression of the sub-plate of the finished plate. In this way, the demand for real-time tracking of steel plates of different specifications and sizes can be met. The whole process is highly automated, reducing manual intervention and errors, and improving production efficiency. In addition, through the tracking impressions of the sub-plates and mother plates, the traceability of the production process is achieved, which is helpful for quality control and troubleshooting.

[0061] See also Figure 7 , a schematic diagram of a steel plate tracking and correction process is shown in an exemplary embodiment of the present application. Figure 7 As shown, first, a coordinate axis is established with the position of the input roller of the cut-to-length shear as the origin, and then cold detection elements are set at fixed intervals on the rollers (including the output roller) in the cut-to-length shear area. When the steel plate (target steel plate or finished plate) enters the cut-to-length shear area, the speed integration method is used to track the position of the steel plate, and when the steel plate passes through the cold detection element, the position of the steel plate is automatically corrected and updated.

[0062] Specifically, updating the sub-board tracking impression of the finished board includes: setting a cold detection element on the roller; determining the actual position of the finished board according to the cold detection signal collected by the cold detection element; and correcting the position obtained by tracking the same finished board based on the actual position of the finished board to update the sub-board tracking impression.

[0063] In one embodiment of the present application, when the finished board passes through the cold detection element for detecting the existence and position of an object, the cold detection element will send a cold detection signal, indicating that the finished board has reached the position. According to the trigger time of the cold detection signal and the running speed of the roller, the actual position of the finished board can be calculated; the position of the finished board obtained based on the speed integral tracking is compared with the actual position determined by the cold detection signal. If there is a deviation, the tracked position is corrected to more accurately reflect the actual position of the finished board; finally, according to the corrected position information, the sub-board tracking impression is updated to ensure the accuracy and continuity of the tracking. In this way, the actual position of the finished board is determined by the cold detection signal, which greatly improves the accuracy and reliability of real-time tracking, is suitable for various production line scenarios, and the automation level of the production line is high.

[0064] Specifically, the finished plate is transmitted, including: determining the current roller area where the finished plate is located, the multiple roller areas are obtained by dividing the roller according to the preset roller length, and each roller area is provided with a cold detection element; if the cold detection signal of the next roller area is detected to be the preset first signal, the finished plate is transmitted from the current finished plate to the next roller area; if the cold detection signal of the next roller area is detected to be the preset second signal, the finished plate is stopped from being transmitted to the next roller area. In this way, the automatic transmission of the finished plate on the roller can be accurately controlled, the waiting time and transmission conflict are reduced, thereby improving production efficiency, and the roller state and the position of the finished plate can be monitored in real time to avoid safety hazards such as collision or stacking. In addition, the structure of the finished plate transmission is simple and low.

[0065] In one embodiment of the present application, the division of the roller area and the setting of the cold inspection element can be adjusted according to actual production needs to adapt to finished plates of different specifications and sizes.

[0066] In an embodiment of the present application, the preset first signal is usually set to 0, and the preset second signal is usually set to 1.
