Description

[0002] The process of winding the slitting machine is to first hoist the steel core onto the unwinding seat through a crane, then the motor drives the chuck to tighten it through a screw rod, and then the conical surface of the chuck is used to squeeze the steel core to the center of the chuck.

[0055] Example 1

[0056] like Figure 1 FIG. 1 is a schematic diagram of the structure of a steel core automatic positioning system 100 in an embodiment of the present application. Figure 2 , which is a physical schematic diagram of a steel core automatic positioning system 100 in an embodiment of the present application, wherein the system includes a touch screen 110 , a PLC controller 120 and a lifting bracket device 130 .

[0057] In this embodiment, the touch screen 110 is used to obtain the bracket parameters input by the user, convert the bracket parameters into a first command signal, and send the first command signal to the PLC controller 120 .

[0058] In an optional embodiment, if Figure 3 As shown, the touch screen 110 includes a first acquisition unit 111, a second acquisition unit 112, a first conversion unit 113 and a first sending unit 114; the first acquisition unit 111 is used to obtain the steel core type selected by the user; the second acquisition unit 112 is used to obtain a preset process recipe, and generate a bracket parameter corresponding to the steel core type according to the preset process recipe, wherein the bracket parameter includes at least one of a preset bracket movement distance, a preset bracket speed and a preset bracket acceleration; the first conversion unit 113 is used to convert the bracket parameter into a first instruction signal; the first sending unit 114 is used to send the first instruction signal to the PLC controller 120.

[0059] Preferably, the steel core automatic positioning system 100 of this embodiment includes a preset process recipe, in which parameters such as moving distance, speed, acceleration, etc. corresponding to steel cores of various types and sizes have been pre-stored. Therefore, after the steel core type selected by the user is obtained through the first acquisition unit 111, the bracket parameters corresponding to the steel core type in the preset process recipe are obtained through the second acquisition unit 112, wherein the bracket parameters include at least one of the preset bracket moving distance, the preset bracket speed, and the preset bracket acceleration.

[0060] Further, the bracket parameter is converted into a first instruction signal by the first conversion unit 113 , and the first sending unit 114 sends the first instruction signal to the PLC controller 120 .

[0061] The introduction of the touch screen 110 in this embodiment greatly simplifies the process of switching steel cores. When different types of steel cores need to be replaced, the user only needs to select a pre-stored process recipe through the touch screen 110, and the system will respond immediately and automatically adjust the relevant parameters, eliminating tedious manual operations. This intelligent operation method not only improves work efficiency and production efficiency, but also significantly reduces operation errors, providing a solid guarantee for the smooth progress of the production process.

[0062] In this embodiment, the PLC controller 120 is used to analyze the first command signal to obtain motor parameters, convert the motor parameters into a second command signal, and send the second command signal to the lifting bracket device 130.

[0063] In an optional implementation, the motor parameters include a preset motor rotation angle, a preset motor speed, and a preset motor acceleration, such as Figure 4 As shown, the PLC controller 120 includes a first calculation unit 121, a second calculation unit 122, a third calculation unit 123, a second conversion unit 124 and a second sending unit 125; the first calculation unit 121 is used to obtain a preset reduction ratio, and calculate a preset motor rotation angle according to the preset reduction ratio and a preset bracket movement distance; the second calculation unit 122 is used to obtain a preset speed ratio, and calculate a preset motor speed according to the preset speed ratio and a preset bracket speed; the third calculation unit 123 is used to obtain a preset acceleration ratio, and calculate a preset motor acceleration according to the preset acceleration ratio and a preset bracket acceleration; the second conversion unit 124 is used to convert the motor parameters into a second command signal; the second sending unit 125 is used to send the second command signal to the lifting bracket device 130.

[0064] Preferably, after receiving the first command signal sent by the touch screen 110, the PLC controller 120 parses the first command signal. The preset reduction ratio is obtained by the first calculation unit 121, and the preset motor rotation angle in the motor parameters is calculated according to the preset reduction ratio and the preset bracket moving distance in the bracket parameters. Exemplarily, if the preset reduction ratio is 1:10, that is, the first calculation unit 121 only needs to multiply the moving distance of the lifting bracket 133 by 10 to obtain the number of rotations of the servo motor 131. For example, if the lifting bracket 133 moves 10 mm, the servo motor 131 rotates 100 times, that is, 36,000 degrees.

[0065] The preset speed ratio is obtained by the second calculation unit 122, and the preset motor speed in the motor parameters is calculated according to the preset speed ratio and the preset bracket speed in the bracket parameters. For example, if the preset speed ratio is 1:60, the second calculation unit 122 only needs to multiply the speed of the lifting bracket 133 by 60 to obtain the speed of the servo motor 131. For example, if the speed of the lifting bracket 133 is 10 mm / s, the speed of the servo motor 131 is 600 rad / s.

[0066] The preset acceleration ratio is obtained by the third calculation unit 123, and the preset motor acceleration in the motor parameters is calculated according to the preset acceleration ratio and the preset bracket acceleration in the bracket parameters. For example, if the preset acceleration ratio is 1:1, the third calculation unit 123 only needs to multiply the acceleration of the lifting bracket 133 by 1 to obtain the acceleration of the servo motor 131. For example, if the acceleration of the lifting bracket 133 is 500 mm / s 2 , then the speed of the servo motor 131 is 500 rad / s 2 .

[0067] Furthermore, the motor parameters are converted into a second command signal through the second conversion unit 124 , and then the second command signal is sent to the lifting bracket device 130 through the second sending unit 125 .

[0068] The PLC controller 120, as the core of the entire steel core automatic positioning system 100, can accurately control the movement of the lifting bracket device 130 according to the information received by the touch screen 110, thereby ensuring that the lifting bracket 133 can move according to preset requirements, ensuring the efficient, stable and reliable operation of the entire system.

[0069] In this embodiment, the lifting bracket device 130 is used to automatically position the steel core according to the second instruction signal.

[0070] In an optional embodiment, if Figure 5 As shown, the lifting bracket device 130 includes a servo motor 131, a lifting reducer 132 and a lifting bracket 133; the servo motor 131 is used to perform rotational motion according to the command signal; the lifting reducer 132 is used to convert the rotational motion of the servo motor 131 into the lifting motion of the lifting bracket 133 through a transmission mechanism; the lifting bracket 133 is used to drive the steel core to automatically position. The servo motor 131 includes a control unit 1311 and a motion unit 1312; the control unit 1311 is used to adjust the target voltage and target current of the servo motor 131 according to the second command signal; the motion unit 1312 is used to drive the servo motor 131 to perform rotational motion according to the target voltage and target current.

[0071] Preferably, after receiving the second command signal, the second command signal is first processed by the control unit 1311 and converted into a control signal that can be recognized by the servo motor 131 (generally involving steps such as signal decoding, amplification and conversion, which are not the invention points of this embodiment and will not be repeated here). These control signals include target voltage and target current (or pulses), etc., and then the motion unit 1312 drives the servo motor 131 to rotate according to the target voltage and target current.

[0072] It is understandable that the servo motor 131 is the core power source of the entire system. It generates rotational motion by receiving the command signal from the PLC controller 120. It has the characteristics of high precision and high response speed, and can ensure the accuracy and stability of the rotational motion. The servo motor 131 can improve the positioning accuracy of the steel core, ensure that the center of the steel core reaches the target position, and is at the same horizontal position as the center of the chuck. This precise positioning not only avoids the problem of unstable clamping, but also effectively prevents slippage between the steel core and the chuck, ensures the stability of the tension of the slitting machine, and improves the yield of the product.

[0073] Next, the high-speed rotational motion of the servo motor 131 is converted into a low-speed, high-torque motion through the transmission mechanism of the lifting reducer 132. The reducer outputs a rotational motion, while the lifting bracket 133 requires a vertical lifting motion. Therefore, a transmission mechanism needs to be provided between the output shaft of the servo motor 131 and the input shaft of the reducer. The transmission mechanism includes a mechanism that converts rotational motion into linear motion, such as a screw lift, a spiral transmission mechanism, etc. These mechanisms convert rotational motion into linear motion through specific mechanical structures (such as threads, gear racks, etc.).

[0074] The output shaft of the lifting reducer 132 drives the transmission mechanism (such as a screw lift) to rotate, and the nut or slider on the screw moves linearly along the screw under the action of the rotational force. The nut or slider is connected to the lifting bracket 133. When they move linearly, they will drive the lifting bracket 133 to achieve vertical lifting movement. Finally, the lifting bracket 133 drives the steel core to achieve lifting and positioning.

[0075] It can be understood that the motion conversion of the lifting reducer 132 is achieved by upgrading the precise gear transmission mechanism inside the reducer. The gear ratio determines the reduction ratio, thereby achieving a reduction in speed and an increase in torque, ensuring the stability and reliability of the automatic positioning process of the steel core.

[0076] The above method upgrades the original fixed bracket to a lifting bracket 133, and by first lifting the steel core to the target position, that is, the center position of the chuck, and then performing the clamping operation, the load on the clamping motor and the screw rod can be greatly reduced. This can not only extend the service life of the motor and the screw rod, reduce the maintenance cost of the equipment, but also reduce the equipment failure rate and improve production efficiency.

[0077] In an optional embodiment, the PLC controller 120 further includes a monitoring unit 126; the monitoring unit 126 is used to monitor the current carriage speed and the current carriage acceleration of the lifting carriage 133 in real time, and generate an alarm signal when the current carriage speed is not equal to the preset carriage speed, or the current carriage acceleration is not equal to the preset carriage acceleration. The monitoring unit 126 is also used to monitor the final carriage moving distance of the lifting carriage 133 in real time, and generate an alarm signal when the final carriage moving distance is not equal to the preset carriage moving distance.

[0078] Preferably, this embodiment can also monitor the current bracket speed, current bracket acceleration and final moving distance of the lifting bracket 133 in real time through the monitoring unit 126, and generate an alarm signal when an abnormal situation occurs, so that the PLC controller 120 can make timely adjustments as needed to ensure the accuracy and stability of the lifting of the lifting bracket 133.

[0079] It should be noted that, in this embodiment, the monitoring of the final moving distance can be achieved by connecting a position sensor (such as a photoelectric encoder, a rotary transformer or a Hall effect sensor, etc.), which can accurately feedback the current position information of the lifting bracket 133 to the monitoring unit 126. After receiving the signal of the position sensor, the monitoring unit 126 will perform data processing and analysis, convert the analog signal into a digital signal, and calculate the actual position of the lifting bracket 133. In addition, although the speed can usually be calculated by the rate of change of the position information, the speed of the lifting bracket 133 can also be directly monitored by connecting a special speed sensor. The acceleration can be obtained by performing a differential operation on the speed signal, or directly measured by an acceleration sensor. The monitoring unit 126 will calculate the acceleration of the lifting bracket 133 based on the real-time speed data or the acceleration sensor signal. The above-mentioned method of measuring position, speed and acceleration is only used as an example. The specific measurement method can be determined according to the actual situation, and the embodiment of the present application does not limit this.

[0080] The above method reduces production delays or errors caused by position deviation or speed instability through the monitoring function of the PLC controller 120, which helps to optimize the production process and improve overall production efficiency.

[0081] The steel core automatic positioning system 100 provided in the embodiment of the present application includes a touch screen 110, a PLC controller 120 and a lifting bracket device 130; the touch screen 110 is used to obtain the bracket parameters input by the user, and convert the bracket parameters into a first instruction signal, and send the first instruction signal to the PLC controller 120; the PLC controller 120 is used to parse the first instruction signal, obtain the motor parameters, convert the motor parameters into a second instruction signal, and send the second instruction signal to the lifting bracket device 130; the lifting bracket device 130 is used to automatically position the steel core according to the second instruction signal. The present application realizes the intelligent and accurate positioning of the steel core through the mutual cooperation between the touch screen 110, the PLC controller 120 and the lifting bracket device 130, and realizes an efficient and stable steel core rolling process.
