Description

Technical Field

[0001] The present application relates to the field of winding technology, and in particular to an oversized roll winding device, method, execution device, electronic equipment and storage medium. Background Art

[0002] In modern industrial production, winders are widely used in the winding of rolled materials such as strapping tape, flat belt, and round wire. Traditional winders are usually suitable for processing coils of smaller size and weight, and the winding weight is generally below 25KG. These winders are usually equipped with a tension control system, which uses a swing arm wheel structure combined with an angle displacement sensor to control the winder speed so that it is consistent with the production line speed, thereby achieving tension adjustment.

[0003] However, as the scale of production expands and the weight of coils increases, traditional winders gradually expose their limitations when handling super-large coils (weighing 350KG to 2.5 tons or even larger). The size and weight of super-large winders are several times that of conventional winders, resulting in a longer transmission path between "production line → tension control structure → winder" and requiring multiple turns. In this case, the coil is easily disturbed by external environmental factors (such as mechanical vibration, air flow, etc.) during transmission, resulting in tension fluctuations and affecting the winding quality.

[0004] As the weight of the coil increases, its rotational inertia increases significantly, which requires the winder to have longer soft start and soft stop times to avoid equipment damage or winding accidents caused by sudden start or stop. When the soft start and soft stop times increase, it means that the acceleration or deceleration time becomes longer, and the time to control the winder to reach the target speed will also become longer.

[0005] Existing technologies are difficult to effectively deal with the tension fluctuation problem caused by the winding process of super-large coils. Especially when encountering external interference or speed fluctuations, traditional tension adjustment devices are prone to violent swings or floating, and cannot stably control the tension, which leads to reduced winding quality or even equipment damage.

[0006] In view of the above problems, the existing technology needs to be improved urgently. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] As the scale of industrial production expands, the oversized coil winding device 200 faces many challenges when handling coils weighing 350KG to 2.5 tons or even larger. When traditional coils handle such oversized coils, the significant increase in volume and weight leads to a longer transmission path. The coils are easily disturbed by external environmental factors during transmission, causing tension fluctuations and affecting the winding quality. In addition, the rotational inertia of oversized coils increases significantly, requiring the coiler to have longer soft start and soft stop times to avoid equipment damage or winding accidents.

[0027] For these issues, refer to Figures 1 to 4 The present application proposes an innovative super-large roll winding device. The device comprises an unwinding device 100, a winding device 200 and a tension control device 300 arranged therebetween. The design of the tension control device 300 is the core innovation of the present application.

[0028] The tension control device 300 is provided with two key buffers: a first buffer and a second buffer. The first buffer is used to buffer the tension fluctuations between the unwinding device 100 and the tension control device 300, while the second buffer is used to buffer the tension fluctuations when the winding device 200 is adjusting the speed. This double buffer design can effectively cope with various tension changes during the winding process of super-large coils.

[0029] Specifically, the first buffer mainly solves the tension fluctuation problem caused by the longer transmission path in the super-large roll scenario. As the volume of the super-large roll winding device 200 increases, the distance from the unwinding device 100 to the tension control device 300 becomes longer. In this process, the coil is more susceptible to external factors such as mechanical vibration or air flow. The setting of the first buffer can absorb the tension fluctuations caused by these external factors and maintain the tension stability of the coil when it enters the tension control device 300.

[0030] The second buffer is mainly for tension fluctuations when the speed of the winding device 200 is adjusted. Due to the increase in weight, the rotational inertia of the oversized coil increases significantly, which requires the winding device 200 to take longer to adjust the speed. In this process, since the winding device 200 will reach the target speed more slowly, there will be a situation where the tension fluctuation cannot be fully buffered. In this case, the setting of the second buffer can effectively alleviate the residual tension fluctuation caused by the slow speed adjustment speed, ensuring the stability of the entire winding process.

[0031] For example, when tension fluctuation occurs during the winding process, assuming that the initial winding speed is a and the tension value is b, the system runs smoothly at this time. When the tension suddenly changes to c (c>b) at time t0, the tension control system calculates that the winding speed needs to be adjusted to d to adapt to the tension change. For ordinary coils (mass m), the winding device 200 can complete the speed adjustment within time t1; while for oversized coils (mass n, where n>>m), due to the significant increase in rotational inertia, the winding device 200 needs a longer time t2 (t2>>t1) to reach the target speed d. In this extended speed adjustment process, the tension value will continue to deviate from the target value b. If only relying on the emergency buffering effect of the first buffer amount, the tension control requirements cannot be met. Therefore, the present application sets a second buffer amount to provide additional buffer space during the process of adjusting the speed from a to d, ensuring that the tension value is always kept within the allowable range of [bx, b+x] during the entire speed adjustment process, where x is the allowable tension fluctuation value, thereby ensuring the winding quality.

[0032] Compared with the prior art, the super-large roll winding device 200 of the present application has significant advantages. The traditional tension control system usually only adopts a single swing arm wheel 340 structure, which is difficult to cope with the complex tension changes caused by super-large rolls. However, by introducing a double buffer design, the present application can not only effectively handle the tension fluctuations caused by the lengthening of the transmission path, but also cope with the tension changes when the unwinding device 100 adjusts the speed. This design greatly improves the stability and reliability of the super-large roll winding process.

[0033] Therefore, the super-large roll winding device 200 of the present application can effectively solve the problems existing in the prior art. Through the carefully designed tension control device 300, the device can maintain stable tension control when processing super-large rolls, significantly improve the winding quality, and reduce the risk of equipment damage. This not only improves production efficiency, but also extends the service life of the equipment.

[0034] It is worth noting that in the process of maintaining tension balance, a substantial solution needs to be achieved by adjusting the rotation speed of the winding device 200 to match the tension fluctuations that occur. The tension control device 300 actually serves as a temporary emergency buffer mechanism because, when the tension fluctuations persist for a long period of time, it is necessary to adapt to it by adjusting the rotation speed of the winding device 200. For example, when the unwinding speed of the unwinding device 100 becomes faster or slower, the winding device 200 needs to match it. In this case, the setting of the second buffer amount becomes crucial.

[0035] Furthermore, the present application also proposes that the tension control device 300 includes a front-stage buffer mechanism 310, a rear-stage buffer mechanism 320 and a swing arm adjustment mechanism. The front-stage buffer mechanism 310 is arranged between the swing arm adjustment mechanism and the unwinding device 100, and the first buffer amount is set by the front-stage buffer mechanism 310. The rear-stage buffer mechanism 320 is arranged between the swing arm adjustment mechanism and the winding device 200, and the second buffer amount is set by the rear-stage buffer mechanism 320.

[0036] This design effectively solves the tension fluctuation problem during the winding process of the super-large roll by introducing the front-stage and rear-stage buffer mechanisms 320 into the tension control device 300. The front-stage buffer mechanism 310 is mainly used to alleviate the tension fluctuation between the unwinding device 100 and the tension control device 300, while the rear-stage buffer mechanism 320 is mainly used to alleviate the tension fluctuation of the winding device 200 when adjusting the speed.

[0037] Specifically, the front-stage buffer mechanism 310 can effectively absorb and alleviate the tension fluctuations caused by the unevenness or external interference that may occur during the unwinding process by being arranged between the swing arm adjustment mechanism and the unwinding device 100. This design can prevent these fluctuations from being directly transmitted to the swing arm adjustment mechanism, thereby ensuring the stability of the entire system.

[0038] The rear buffer mechanism 320 is arranged between the swing arm adjustment mechanism and the winding device 200, and its main function is to alleviate the tension fluctuation of the winding device 200 when adjusting the speed.

[0039] As a preferred embodiment, the front-stage buffer mechanism 310 can use elastic elements or hydraulic buffer devices to achieve the buffering function. For example, a series of spring components or cylinder devices can be used, which can be extended and retracted according to the change of tension, thereby achieving a smooth transition of tension.

[0040] Similarly, the rear buffer mechanism 320 may also adopt a similar design. Thus, different buffer elements may be selected according to actual needs to adapt to different winding speeds and tension requirements.

[0041] The swing arm adjustment mechanism plays a key role in the entire system. It can adjust the position of the swing arm in time by sensing the change of tension, thereby achieving precise control of the tension. For example, a tension sensor can be installed on the swing arm to monitor the change of tension in real time and fine-tune the position of the swing arm through the control system.

[0042] The technical solution of the present application effectively improves the stability and reliability of the super-large roll winding device 200 by reasonably setting the front-stage buffer mechanism 310, the rear-stage buffer mechanism 320 and the swing arm adjustment mechanism. This design can not only cope with various tension fluctuations during unwinding and winding, but also adapt to super-large roll materials of different specifications and weights. Therefore, the present application solves the tension control problem faced by the traditional winding device 200 when processing super-large rolls, and significantly improves the winding quality and production efficiency.

[0043] Furthermore, the present application also proposes that the ratio of the length of the first buffer amount to the distance from the front-stage buffer mechanism 310 to the unwinding device 100 is 1:10.

[0044] This technical solution aims to optimize the design of the front buffer mechanism 310 in the tension control device 300. Specifically, by setting a specific proportional relationship between the length of the first buffer amount and the distance from the front buffer mechanism 310 to the unwinding device 100, the tension fluctuation generated between the unwinding device 100 and the tension control device 300 can be more effectively buffered.

[0045] In practical applications, the length of the first buffer can be adjusted according to the specific equipment size and production requirements. For example, if the distance from the front buffer mechanism 310 to the unwinding device 100 is 10 meters, the length of the first buffer should be set to 1 meter. The setting of this proportional relationship is not arbitrary, but is based on in-depth research on tension fluctuation characteristics and practical experience.

[0046] As a preferred embodiment, an adjustable mechanism can be provided on the front-stage buffer mechanism 310 so as to fine-tune the length of the first buffer amount under different production conditions. This adjustability can improve the adaptability of the device, so that it can maintain a good tension control effect during the winding process of oversized coils of different types or weights.

[0047] Therefore, by accurately controlling the length of the first buffer, the tension fluctuation during the unwinding process can be better absorbed and alleviated. This design can not only improve the quality of winding, but also reduce the risk of equipment damage caused by sudden tension changes. Compared with the prior art, the setting of this proportional relationship provides a more accurate and stable tension control solution for the super-large coil winding device 200, effectively solving the tension control problem faced by traditional winders when processing super-large coils.

[0048] Furthermore, the present application also proposes that the length of the second buffer satisfies: L>Vo t + a t2; wherein, L is the length of the second buffer; Vo is the initial velocity of the winding device 200 before acceleration or deceleration at the maximum diameter, Vo is the linear velocity; t is the first acceleration time or the first deceleration time; a is the acceleration.

[0049] This technical solution is intended to solve the tension problem caused by the slow speed adjustment of the winding device 200 during the winding of the super-large roll. By setting a suitable second buffer length, the tension fluctuation of the winding device 200 during the acceleration or deceleration process can be effectively buffered, thereby ensuring the winding quality.

[0050] Specifically, the length L of the second buffer needs to be greater than Vo t + a t2. This formula takes into account the initial linear velocity Vo, acceleration a, and acceleration or deceleration time t of the winding device 200. Among them, Vo t represents the distance that the winding device 200 runs at the initial velocity, and a t2 represents the additional distance during the acceleration or deceleration process. By ensuring that the length of the second buffer is greater than the sum of these two parts, sufficient buffer space can be provided for the winding device 200 to cope with the tension fluctuation caused by speed changes.

[0051] Thus, the length of the second buffer can be flexibly adjusted according to actual production requirements. For example, for a winding device 200 with a larger diameter, its initial linear velocity Vo may be higher, and a longer second buffer may be required. Similarly, if a larger acceleration or a longer acceleration time is required during the production process, the length of the second buffer should also be increased accordingly.

[0052] As a preferred embodiment, the optimal second buffer length can be determined by experiment or simulation calculation. Furthermore, it can be considered to add an automatic adjustment mechanism to the control system to calculate the required second buffer length in real time according to the current winding diameter, target speed and other parameters, and adjust the position of the buffer mechanism accordingly.

[0053] The advantage of this design is that it can effectively meet the special needs of the super-large coil winding process. Since the super-large coil has a large rotational inertia and requires a long acceleration or deceleration time, the traditional tension control method may not be able to respond in time. By reasonably setting the length of the second buffer amount, sufficient buffer space can be provided for the winding device 200, effectively reducing the impact of speed changes on tension, thereby improving winding quality and production efficiency.

[0054] Furthermore, the present application also proposes a swing arm adjustment mechanism of an oversized roll winding device 200. The mechanism includes a first mounting frame 330 and a swing arm wheel 340 disposed on the first mounting frame 330. The first mounting frame 330 is composed of two first vertical rods 331 spaced apart and vertically disposed and a first cross bar 332 transversely connecting the two first vertical rods 331. The swing arm wheel 340 is hinged on the first cross bar 332, and the first vertical rod 331 is provided with a first guide wheel 333 and a first driving mechanism 334. The first driving mechanism 334 is connected to the swing arm wheel 340, and can drive the swing arm wheel 340 to approach or move away from the first guide wheel 333.

[0055] The front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320 are respectively arranged on two first vertical rods 331. The front-stage buffer mechanism 310 includes a first mounting plate 311 connected to the first vertical rod 331, on which one or more spaced first fixed wheels 312 are fixedly arranged, and between the plurality of spaced first fixed wheels 312, a first floating wheel 313 capable of moving up and down is arranged. There is a height difference between the setting positions of the first floating wheel 313 and the first fixed wheel 312. A buffer member 314 for contacting the first floating wheel 313 is also arranged on the first mounting plate 311, and the buffer member 314 stores energy when the first floating wheel 313 moves up and down. The rear-stage buffer mechanism 320 adopts the same structure as the front-stage buffer mechanism 310.

[0056] Specifically, the structural design of the first mounting frame 330 provides stable support to ensure the normal operation of the swing arm wheel 340 and the buffer mechanism. The articulated setting of the swing arm wheel 340 and the cooperation of the first driving mechanism 334 enable the swing arm wheel 340 to flexibly adjust its position and effectively control the tension. The setting of the first guide wheel 333 further optimizes the transmission path of the coil.

[0057] The design of the front buffer mechanism 310 and the rear buffer mechanism 320 is a key innovation of the present application. The combination of the first fixed wheel 312 and the first floating wheel 313, and the height difference between them, provide a flexible buffer space for the coil. When the tension of the coil changes, the first floating wheel 313 can move up and down, and cooperate with the buffer 314 to achieve dynamic adjustment of tension and energy storage.

[0058] As a preferred embodiment, the buffer 314 can be in the form of a spring, a cylinder or a hydraulic cylinder. For example, when a compression spring is used as the buffer 314, a suitable spring stiffness can be selected according to the weight of the coil and the expected tension variation range. When the tension increases, the first floating wheel 313 moves upward; when the tension decreases, the first floating wheel 313 moves downward, thereby maintaining a relatively stable tension.

[0059] Therefore, the swing arm adjustment mechanism of the present application effectively solves the tension fluctuation problem during the winding process of the super-large roll by setting the front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320. This design can not only cope with external interference during the coil transmission process, but also provide additional buffering capacity when the winder accelerates or decelerates. This dual buffer mechanism significantly improves the stability and controllability of the winding process, and helps to improve the quality and efficiency of the winding of super-large rolls.

[0060] Different from the above scheme, in another embodiment, the present application further proposes that the tension control device 300 includes a second vertical rod 351, on which a second floating wheel 352 and a third floating wheel 353 are movably arranged in a vertically staggered manner, an elastic member 354 is arranged between the second floating wheel 352 and the second vertical rod 351, a rotating head 355 is arranged on the second vertical rod 351, a connecting rod 356 is arranged between the rotating head 355 and the third floating wheel 353, and an angle sensor is arranged on the rotating head 355 for detecting the rotation angle of the connecting rod 356.

[0061] Compared with the above solution, the solution of this embodiment can save space.

[0062] This design can respond to tension changes more sensitively by movably setting two vertically offset floating wheels on the second vertical rod 351. The elastic member 354 between the second floating wheel 352 and the second vertical rod 351 can provide preliminary tension buffering, and the third floating wheel 353 is connected to the rotating head 355 through the connecting rod 356, which can convert tension changes into angle changes. The angle sensor detects the rotation angle of the connecting rod 356, thereby realizing accurate monitoring of tension changes.

[0063] Specifically, the vertical offset arrangement of the second floating wheel 352 and the third floating wheel 353 can increase the sensitivity of tension detection. When the tension of the coil changes, the third floating wheel 353 will be displaced, and this difference can be converted into an angle change of the connecting rod 356. The elastic member 354 can be a spring, a cylinder or other components with elastic properties, and its stiffness can be adjusted according to actual needs to adapt to coils of different weights and materials.

[0064] The rotating head 355 can be mounted on the second vertical rod 351 by bearing support to ensure that it can rotate flexibly. The connecting rod 356 can be made of light and high-strength materials, such as carbon fiber or aluminum alloy, to reduce the influence of its own weight on the measurement accuracy. The angle sensor can use a high-precision photoelectric encoder or a magnetic angle sensor to ensure the accuracy and real-time performance of the angle measurement.

[0065] As a preferred embodiment, a data processing unit can be added to the system to convert the data of the angle sensor into an actual tension value, and automatically adjust the speed of the winding device 200 or other parameters of the tension control device 300 according to a preset tension range. In addition, it is also possible to consider adding a temperature compensation device to the second vertical rod 351 to eliminate the influence of ambient temperature changes on the measurement accuracy.

[0066] In some specific embodiments, with the horizontal direction as 0 degrees, the vertical direction as 90 degrees, and the horizontal position of the angle sensor as a reference, the buffer amount generated by the moving stroke of the third floating wheel 353 within a range of 59 degrees below the horizontal position is used as the first buffer amount, and the buffer amount generated by the moving stroke of the third floating wheel 353 within a range of 73 degrees above the horizontal position is used as the second buffer amount.

[0067] In the above scheme, since the structure occupies less space, in order to have sufficient buffering capacity, the second floating wheel 352 and the third floating wheel 353 can be arranged to extend in the horizontal direction and have winding tracks for multiple material belts, so that the material belts can be wound multiple times, thereby having sufficient buffering capacity.

[0068] Furthermore, the present application also proposes a super-large roll winding method, which is applied to the above-mentioned super-large roll winding device 200. The method includes two main steps: when a tension change occurs between the unwinding device 100 and the tension control device 300, a first buffer is used for buffering; when a tension change occurs between the winding device 200 and the tension control device 300, a second buffer is used for buffering.

[0069] Specifically, the method uses two buffers in the tension control device 300 to cope with tension changes in different situations. The first buffer is mainly used to handle tension fluctuations between the unwinding device 100 and the tension control device 300. When tension changes occur during the unwinding process, the first buffer can absorb these fluctuations and prevent them from being transmitted to the entire system. This helps maintain the stability of the coil during transmission and reduces the impact of external factors such as mechanical vibration, air flow, etc. on tension.

[0070] On the other hand, the second buffer is mainly used to cope with the tension fluctuations generated when the winding device 200 is adjusting the speed. Since the oversized coil has a large rotational inertia, the winding device 200 accelerates or decelerates slowly, and there are tension changes that are not buffered due to the slow speed to reach the target speed. The design of the second buffer can effectively alleviate this situation and ensure that a relatively stable tension is maintained during the speed adjustment process.

[0071] As a preferred embodiment, the first buffering amount can be achieved by the front-stage buffering mechanism 310, which is arranged between the swing arm adjustment mechanism and the unwinding device 100. The second buffering amount can be achieved by the rear-stage buffering mechanism 320, which is arranged between the swing arm adjustment mechanism and the winding device 200. This layout can effectively handle the tension changes during the unwinding and winding processes respectively.

[0072] In some specific embodiments, the first floating wheel 313 on the front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320 is provided with a driving mechanism, which can be a cylinder or a motor-screw transmission structure, and the tension can be adjusted in an active control manner. Specifically, for the super-large reel winding device 200 having the front-stage buffer mechanism 310, the rear-stage buffer mechanism 320 and the swing arm adjustment mechanism, the swing arm adjustment mechanism is the structure initially used to maintain tension balance, because it has a first driving mechanism 334. When tension fluctuations are detected, the balance can be maintained in the first time by active control. Its reaction speed is fast, however, its adjustment stroke is limited. In this regard, by providing a driving mechanism on the front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320, the front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320 can also be enabled to actively adjust the tension.

[0073] In some specific embodiments, when tension fluctuation occurs, the tension fluctuation amplitude is detected by a sensor, and then the tension adjustment amplitude of the current swing arm adjustment mechanism is obtained, and the remaining tension fluctuation fluctuation is calculated based on the tension fluctuation amplitude and the tension adjustment amplitude, and then the front-stage buffer mechanism 310 or the rear-stage buffer mechanism 320 is controlled to perform active tension adjustment based on the remaining tension fluctuation fluctuation. In this way, the swing arm adjustment mechanism can be protected for safety.

[0074] Furthermore, the present application also proposes an execution device, including a first control module and a second control module. The first control module is used to use a first buffer amount for buffering when a tension change occurs between the unwinding device 100 and the tension control. The second control module is used to use a second buffer amount for buffering when a tension change occurs between the winding device 200 and the tension control.

[0075] The actuator manages the tension changes at the unwinding end and the winding end respectively through two independent control modules, thus realizing precise control of the tension during the entire winding process. The first control module is mainly responsible for handling the tension fluctuation between the unwinding device 100 and the tension control device 300, while the second control module focuses on the tension changes between the winding device 200 and the tension control device 300. This design with clear division of labor helps to more accurately deal with tension problems that may occur at different stages.

[0076] As a preferred embodiment, the first control module and the second control module can be implemented by an electronic control unit (ECU) or a programmable logic controller (PLC). These controllers can quickly respond and adjust the working state of the buffer mechanism by real-time monitoring the data of the tension sensor. In this way, dynamic real-time control of the tension can be achieved, and the stability and reliability of the entire winding process can be improved.

[0077] In addition, the first control module and the second control module can exchange data and work together. For example, when the first control module detects a large tension fluctuation at the unwinding end, this information can be transmitted to the second control module so that it can prepare for the response in advance. This collaborative working mechanism can further improve the response speed and control accuracy of the entire system.

[0078] Furthermore, the present application also proposes an electronic device, including a processor and a memory, wherein the memory stores computer-readable instructions. When the computer-readable instructions are executed by the processor, the steps in the super-large roll winding method are executed.

[0079] The electronic device may be a dedicated control device or a general-purpose computer device. The processor may be a central processing unit (CPU), a graphics processing unit (GPU) or a dedicated digital signal processor (DSP), etc. The memory may include a random access memory (RAM), a read-only memory (ROM), a flash memory, etc.

[0080] Specifically, the computer-readable instructions stored in the memory include specific steps of the super-large roll winding method. When these instructions are executed by the processor, the electronic device will perform the following operations: when the tension between the unwinding device 100 and the tension control device 300 changes, the first buffer amount is used for buffering; when the tension between the winding device 200 and the tension control device 300 changes, the second buffer amount is used for buffering.

[0081] As a preferred embodiment, the electronic device can monitor the tension changes between the unwinding device 100, the winding device 200 and the tension control device 300 in real time through various sensors. For example, tension sensors can be installed at key positions to continuously collect tension data. The processor determines whether to start the buffer mechanism based on the collected data and controls the corresponding buffer device to work.

[0082] The first buffering amount and the second buffering amount can be achieved by adjusting the position of the floating wheels in the front buffering mechanism 310 and the rear buffering mechanism 320. The processor can accurately control the displacement of the floating wheel according to the detected tension change degree, so as to achieve the best buffering effect.

[0083] Therefore, the electronic device proposed in this application can effectively deal with various tension fluctuations in the process of winding super-large rolls through intelligent control, thereby improving the winding quality and equipment stability. This solution fully utilizes the advantages of computer technology, realizes precise control of complex winding systems, and solves technical problems that are difficult to overcome with traditional mechanical solutions.

[0084] Furthermore, the present application also proposes a storage medium on which a computer program is stored. When the computer program is executed by a processor, the steps in the super-large roll winding method are executed.

[0085] Specifically, the storage medium can be various types of computer-readable storage devices or memories, such as a hard disk, a solid-state hard disk, an optical disk, a USB flash drive, a memory card, etc. The computer program stored on the storage medium includes a set of instructions for executing the super-large roll winding method. When the computer program is loaded into the processor and executed, the processor will execute each step in the super-large roll winding method.

[0086] The method for winding a super-large roll includes two main steps: when a tension change occurs between the unwinding device 100 and the tension control device 300, a first buffer is used for buffering; when a tension change occurs between the winding device 200 and the tension control device 300, a second buffer is used for buffering. These two steps correspond to the tension control in the unwinding process and the winding process, respectively.

[0087] Thus, by storing a computer program including the above steps on a storage medium, automatic control of the super-large roll winding device 200 can be achieved. The processor can monitor the tension change between the unwinding device 100 and the winding device 200 and the tension control device 300 in real time according to the program instructions, and timely call the corresponding buffer amount to adjust the tension.

[0088] As a preferred embodiment, the computer program may further include instructions for controlling the front-stage buffer mechanism 310 and the rear-stage buffer mechanism 320. For example, the program may control the up and down movement of the first floating wheel 313 in the front-stage buffer mechanism 310 and the floating wheel in the rear-stage buffer mechanism 320 according to the detected tension change, thereby achieving more precise tension control.

[0089] Furthermore, the computer program may also include instructions for processing angle sensor data. By analyzing the rotation angle of the connecting rod 356 detected by the angle sensor, the program can more accurately determine the tension change, thereby making a more reasonable buffer adjustment decision.

[0090] The computer program stored on the storage medium effectively solves the tension fluctuation problem in the process of winding super-large coils by implementing the above-mentioned super-large coil winding method. Compared with the traditional technology, the method proposed in this application can better cope with external interference and speed fluctuations, avoid violent swinging or floating, thereby improving the winding quality and reducing the risk of equipment damage. In addition, the automated control realized by software also improves the convenience and accuracy of operation, providing strong support for the practical application of the super-large coil winding device 200.

[0091] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
