[0002] After the strip product is produced, it usually needs to enter the winder to be collected and rolled.

[0003] In the actual production process, when the side guide plate clamps the edge of the strip product in the pressure ring state, it is very easy for the side guide plate to fail to reach the set target pressure value and continue to clamp inward due to insufficient rigidity in the width direction of the strip product, which will cause edge defects of the strip product, seriously affecting product quality and production progress.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] See below Figure 1 , Figure 1 A flow chart of a coiler control method provided in an embodiment of the present application.

[0047] Specific steps may include:

[0048] S101: Detecting the working state of the reel;

[0049] Among them, this embodiment can be applied to a coiler, which includes a reel and a side guide plate, wherein the reel is used to collect the coiled object into a coil, and the side guide plate is used to guide the coiled object into the reel and ensure that the edges of the coiled object are neat after being coiled. The coiled object can be a strip product that needs to be coiled, such as a steel strip, an iron strip, an aluminum strip, a plastic strip, a paper strip, etc., which is not specifically limited here.

[0050] The working state of the reel may include a loaded state and an unloaded state. The loaded state refers to a state where the object to be rolled has entered the reel, and the unloaded state refers to a state where the object to be rolled has not entered the reel. In this embodiment, the working state of the reel may be detected based on devices such as a pressure sensor, a light sensor, and a distance sensor.

[0051] S102: If the working state of the reel is a loaded state, controlling the hydraulic cylinder corresponding to the side guide plate to enter a pressure ring control mode so that the side guide plate clamps the reeled object;

[0052] Among them, this step is based on the fact that the reel is already in a loaded state. At this time, the hydraulic cylinder corresponding to the side guide plate can be controlled to enter the pressure ring control mode so that the side guide plate can clamp the edge of the winding object under the pressure ring control mode.

[0053] S103: Detecting the winding width of the winding object, and calculating a locking trigger value according to the winding width and the anti-folding coefficient;

[0054] Among them, this embodiment can detect the winding width of the winding object, and the winding width is the width of the winding object in the direction perpendicular to the winding direction; after obtaining the winding width, the product of the winding width and the anti-folding coefficient can be used as the locking trigger value.

[0055] The anti-folding coefficient can be a parameter input by the user on the coiler, or a parameter determined by the coiler according to the product model of the coiled object. Specifically, the anti-folding coefficient is related to the thickness, material type, shape and other parameters of the coiled object. This embodiment can determine the anti-folding coefficient corresponding to each product model based on the above parameters.

[0056] S104: Determine whether the current stroke length of the side guide plate is greater than or equal to the locking trigger value; if so, proceed to S105; if not, end the process;

[0057] Before this step, there may be an operation of obtaining the stroke length of the side guide plate according to a preset period, and the stroke length obtained in the current period may be used as the current stroke length of the side guide plate. This step compares the current stroke length with the locking trigger value. If the current stroke length is greater than or equal to the locking trigger value, it means that in the current state, the cross section of the winding object may be arched or the edge may be raised due to insufficient rigidity in the width direction of the winding object, so the relevant operation of S105 can be performed. If the current stroke length is less than the locking trigger value, this operation can be terminated; as a feasible implementation method, if the current stroke length is less than the locking trigger value, after a preset delay, the step of re-entering S104 to determine whether the current stroke length of the side guide plate is greater than or equal to the locking trigger value can be performed, thereby realizing the periodic judgment of the current stroke length of the side guide plate.

[0058] S105: Control the hydraulic cylinder corresponding to the side guide plate to exit the pressure ring control mode, and lock the position of the side guide plate.

[0059] Among them, this step is based on the fact that the current stroke length of the side guide plate is greater than or equal to the locking trigger value. At this time, in order to avoid the edge bending phenomenon during the coiling process, the hydraulic cylinder corresponding to the side guide plate can be controlled to exit the pressure ring control mode and lock the position of the side guide plate so that the stroke length of the side guide plate no longer increases until the current operation of the coiler is completed.

[0060] This embodiment controls the hydraulic cylinder corresponding to the side guide plate to enter the pressure ring control mode after the reel is in the loaded state, thereby causing the side guide plate to clamp the edge of the winding object. This embodiment calculates the locking trigger value according to the winding width and the anti-folding coefficient of the winding object. When the stroke length of the side guide plate is greater than or equal to the locking trigger value, the cross-section of the winding object will be arched or the edge will bulge due to insufficient rigidity in the width direction of the winding object. This embodiment exits the pressure ring control mode and locks the position of the side guide plate after the current stroke length of the side guide plate is greater than or equal to the locking trigger value, which can effectively avoid the side guide plate from constantly clamping inwards because it has not reached the set target pressure value. Therefore, this embodiment can avoid the folding phenomenon in the winding process and improve the control accuracy of the winder.

[0061] As for Figure 1 Further introduction to the corresponding embodiment, in this embodiment, a pressure sensor can be set on the reel, and accordingly, the working state of the reel can be determined in the following manner: the pressure value of the pressure sensor is obtained, and the working state of the reel is determined according to the pressure value; wherein, when the pressure value is greater than a preset value, the working state of the reel is a loaded state; when the pressure value is less than or equal to the preset value, the working state of the reel is an unloaded state.

[0062] As for Figure 1 Further introduction to the corresponding embodiment, the correspondence between each product model and the anti-folding coefficient can be pre-stored in the winder. Before calculating the locking trigger value according to the winding width and the anti-folding coefficient, the anti-folding coefficient corresponding to the product model of the winding object is selected according to the above correspondence.

[0063] As for Figure 1 Further introduction to the corresponding embodiment, after the position of the side guide is locked, the stroke length of the guide will no longer change, so that the reel can perform the reeling operation when the side guide is in the locked position. When the reeling operation is completed, the reeling object completely leaves the reel, and the side guide can change the stroke length to perform the next reeling operation. Therefore, after locking the position of the side guide, this embodiment can determine whether the working state of the reel is an unloaded state; if so, release the position lock of the side guide; if not, continue to lock the position of the side guide.

[0064] As for Figure 1 Further introduction to the corresponding embodiment, before determining whether the current stroke length of the side guide plate is greater than or equal to the locking trigger value, the magnetic scale stroke value of the hydraulic cylinder corresponding to the side guide plate can also be obtained, and the current stroke length of the side guide plate is determined according to the magnetic scale stroke value. The above magnetic scale stroke value is the absolute value of the current position of the hydraulic cylinder magnetic scale minus the zero position.

[0065] As for Figure 1 According to the further introduction of the corresponding embodiment, the winder also includes an operation display screen for displaying and inputting the anti-folding coefficient, and can also be used to select to activate or disable the pressure ring control locking function. Therefore, before detecting the working state of the reel, the pressure ring control locking function of the winder can also be controlled to be in an activated state.

[0066] The process described in the above embodiment is explained below through a solution for preventing the hot-rolled steel strip from bending in a hot-rolled steel strip production line.

[0067] In the hot-rolled steel strip production line, the steel strip must enter the coiler to be collected and coiled after the rolling production is completed. The side guide of the coiler is a part of the coiler. Its main function is to guide the head of the steel strip into the coiler drum and clamp the edge of the steel strip after the head of the steel strip enters the drum to ensure that the edge of the steel strip is neat after the steel strip is coiled. Figure 2 and Figure 3 , Figure 2 The present invention provides a schematic diagram of a process in which a coiler collects a steel strip during a steel strip production process. Figure 3 This is a schematic diagram of a control form of a steel strip and a side guide provided in an embodiment of the present application. In the figure, 1 represents the steel strip, 2 represents the side guide of the coiler, 3 represents the coiler drum, 4 represents the width gauge, and 5 represents the hydraulic cylinder of the side guide. The figure also shows the rolling direction of the strip and the clamping direction of the side guide. Figure 2 As shown in the figure, after the hot-rolled steel strip is rolled, it needs to be collected into coils by a coiler. Figure 3 As shown, the head of the hot-rolled steel strip needs to be guided by the side guide plates, and the side guide plates on both sides are driven by hydraulic cylinders to clamp the sides of the steel strip.

[0068] The control mode of the side guide plate of the coiler is generally divided into two stages of control. The first stage of control is that before the head of the steel strip enters the reel, the side guide plate is in the position loop control mode, that is, the side guide plate is positioned according to the width specification of the steel strip to guide the head of the steel strip; the second stage of control is that after the head of the steel strip enters the reel, the side guide plate is in the pressure loop control mode, that is, at this time the side guide plate clamps the steel strip inward and keeps the oil pressure sensor of the side guide plate hydraulic cylinder at the set constant pressure value, so as to dynamically clamp the edge of the steel strip.

[0069] In the actual production of some extremely thin steel strips, when the side guides clamp the edge of the steel strip in the pressure ring state, it is very easy to have insufficient rigidity in the width direction of the steel strip, and the side guides cannot reach the set target pressure value and continue to clamp inward, resulting in the cross section of the steel strip being arched or the edge bulging, which in turn causes the edge folding defect of the steel strip. When the side guides squeeze the edge of the steel strip heavily, the steel strip may even break and pile up, seriously affecting product quality and smooth production. Figure 4 , Figure 4 This is a schematic diagram of a steel strip cross-section being squeezed and bulged by a side guide plate provided in an embodiment of the present application. Figure 4 As shown, when producing thin-gauge steel strips, due to insufficient rigidity in the cross-sectional direction of the steel strips, bulging of the edges is likely to occur during the clamping process of the side guide plates, thereby causing folding defects. The figure also shows the clamping direction of the side guide plates, 1 represents the steel strip, and 5 represents the hydraulic cylinder corresponding to the side guide plates.

[0070] In order to solve the technical problems existing in the above-mentioned related technologies, this embodiment provides a solution to prevent the hot-rolled steel strip from being folded. The coiler used in this solution includes: a width gauge, a control unit, a coiler side guide plate hydraulic cylinder, a coiler drum pressure sensor, and an operation display screen; the control unit is respectively connected to the width gauge, the coiler side guide plate hydraulic cylinder, the coiler drum, and the operation display screen.

[0071] Specifically, the width gauge is used to send the actual width information of the steel strip to the control unit. The control unit is used to read the steel strip width information of the width gauge, calculate the side guide locking trigger value X according to the anti-folding coefficient input on the operation display screen, read the side guide hydraulic cylinder stroke value Y, and issue instructions to the side guide hydraulic cylinder according to the comparison result of the two values. The side guide hydraulic cylinder of the coiler is equipped with a displacement sensor and an oil pressure sensor, which are used to send the stroke value of the side guide to the control unit, and at the same time, it is used as an actuator to implement functions such as side guide pressure ring control and side guide position locking according to the instructions issued by the control unit. The coiler drum is equipped with a pressure sensor, which is used to determine the position of the steel strip head, and serves as a trigger signal for the control unit to determine the side guide to open the pressure control ring. The operation display screen is used to display and input the anti-folding coefficient, and select the "pressure control locking function" to be used or disabled.

[0072] See also Figure 5 , Figure 5 This is a schematic diagram of the function activation and anti-folding coefficient input interface in an operation display screen provided in an embodiment of the present application. The operator can select the ON state of the coiler side guide pressure ring control locking function, the steel strip head enters the coiler reel, and the coiler side guide enters the pressure ring control state. At this time, the control unit receives the steel strip width information L provided by the width gauge and reads the following information: Figure 6 The operator enters the anti-folding coefficient x% (such as 0.8%) in the operation display screen, and the locking trigger value X=L*x%; at this time, the control unit reads the side guide plate hydraulic cylinder stroke value Y according to a certain period T and compares it with the trigger value. When X≤Y, it is considered that the steel strip has a high risk of occurrence of Figure 4The control unit issues a command to let the side guide plate exit the pressure ring control and lock the position, and maintain the current clamping state until the steel strip is coiled. When X>Y, it is considered that the risk of steel strip folding is low, and the side guide plate pressure ring control is maintained and the value Y and trigger value X are judged until X≤Y is locked or the steel strip is coiled. In this embodiment, a "pressure control ring locking function" is added to the front side guide plate control module of the coiler of the hot-rolled strip production line, and an "anti-folding control coefficient" function block is set, and the program module is linked. By using the "pressure control ring locking function", after the strip is bitten into the coiler and the side guide plate is in the pressure ring control mode, when the magnetic ruler detects that the side guide plate displacement Y exceeds the anti-folding control coefficient, the side guide plate exits the pressure ring control and locks the position, thereby preventing the folding problem caused by the excessive extrusion of the side guide plate stroke on the edge of the strip, improving the quality assurance capability of the strip edge and the stability of hot-rolled strip production.

[0073] See also Figure 6 , Figure 6 A flowchart of a method for preventing hot-rolled steel strip from folding provided in an embodiment of the present application may specifically include the following operations:

[0074] Step 1: The "pressure control lock function" on the operating display is in use.

[0075] Step 2: When the coiler drum pressure sensor is in a loaded state, the control unit determines that the steel strip head enters the drum and issues a first instruction to control the coiler side guide plate hydraulic cylinder to enter the pressure control loop control.

[0076] Step 3: The control unit reads the actual width value L of the steel strip transmitted by the width gauge of the production line and the anti-folding control coefficient x% input in the operation display screen, and calculates the side guide plate locking trigger value X=L*x%.

[0077] Step 4: The control unit reads the magnetic scale stroke value Y of the side guide plate hydraulic cylinder according to a certain time period T; Y∈{Y1, Y2, ..., Yn}; Y1~Yn is the absolute value of the current position of the hydraulic cylinder in each cycle minus the zero position.

[0078] Step 5: The control unit compares the Y collected in each cycle with the locking trigger value X in turn.

[0079] Step 6: When X>Y, the control unit returns to step 4 until the drum pressure sensor is in an unloaded state. The control unit determines that the steel strip leaves the drum and the winding operation is completed, and the control process ends.

[0080] Step 7: When X≤Y, the control unit issues a second instruction to control the coiler side guide plate hydraulic cylinder to exit the pressure control loop control, and lock the coiler side guide plate hydraulic cylinder so that the side guide plate remains in the current position until the drum pressure sensor is in a no-load state. The control unit determines that the steel strip leaves the drum to complete the coiling operation, and the control process ends.

[0081] In this embodiment, a conditional exit and locking position mechanism is added to the original coiler side guide in the pressure ring control mode, so as to solve the problem of squeezing and folding the edge of the steel strip caused by insufficient rigidity of the coiler side guide in the width direction of the steel strip when the steel strip is extremely thin. On the basis of ensuring a certain coil shape of the steel strip, serious quality defects that may cause the steel strip to be scrapped are avoided. At the same time, production accidents such as steel piling caused by serious folding are avoided, thereby improving product quality and production stability.

[0082] The embodiment of the present application also provides a coiler control device, wherein the coiler includes a reel and a side guide plate, and the device may include:

[0083] A state detection module, used for detecting the working state of the reel;

[0084] A side guide plate control module, used for controlling the hydraulic cylinder corresponding to the side guide plate to enter a pressure ring control mode if the working state of the reel is a loaded state, so that the side guide plate clamps the reeled object;

[0085] A trigger value calculation module, used for detecting the winding width of the winding object, and calculating a locking trigger value according to the winding width and the anti-folding coefficient;

[0086] The anti-folding module is used to determine whether the current stroke length of the side guide plate is greater than or equal to the locking trigger value; if so, the hydraulic cylinder corresponding to the side guide plate is controlled to exit the pressure ring control mode and lock the position of the side guide plate.

[0087] This embodiment controls the hydraulic cylinder corresponding to the side guide plate to enter the pressure ring control mode after the reel is in the loaded state, thereby causing the side guide plate to clamp the edge of the winding object. This embodiment calculates the locking trigger value according to the winding width and the anti-folding coefficient of the winding object. When the stroke length of the side guide plate is greater than or equal to the locking trigger value, the cross-section of the winding object will be arched or the edge will bulge due to insufficient rigidity in the width direction of the winding object. This embodiment exits the pressure ring control mode and locks the position of the side guide plate after the current stroke length of the side guide plate is greater than or equal to the locking trigger value, which can effectively avoid the side guide plate from constantly clamping inwards because it has not reached the set target pressure value. Therefore, this embodiment can avoid the folding phenomenon in the winding process and improve the control accuracy of the winder.

[0094] Furthermore, it also includes:
