[0018] When the distance is greater than the third preset threshold and the thickness information is greater than or equal to the fourth preset threshold, the ratio of the first winding tension to the preset winding tension is 1.3 to 1.7, and the second winding tension is equal to the preset winding tension.

[0019] When the distance is less than or equal to the third preset threshold and the thickness information is less than the fourth preset threshold, the ratio of the first winding tension to the preset winding tension is 2.0 to 2.4, and the second winding tension is equal to the preset winding tension.

[0022] According to any of the foregoing embodiments of the first aspect of this application, the second outer diameter of the winding machine's spool is d, the first preset threshold is (d+80mm) to (d+120mm), and the second preset threshold is (d+180mm) to (d+230mm).

[0023] A second aspect of this application provides a control device for controlling a winding device, the winding device including a winding machine and a tension roller. The control device includes a first acquisition module and a control module. The first acquisition module is used to acquire a first outer diameter of a target roll material, the target roll material being wound around the winding machine's reel. The control module is used to control the winding tension of the tension roller according to the first outer diameter, wherein, when the first outer diameter is less than or equal to a first preset threshold, the winding tension of the tension roller is controlled to be a first winding tension; when the first outer diameter is greater than the first preset threshold and less than or equal to a second preset threshold, the winding tension of the tension roller is controlled to decrease from the first winding tension to a second winding tension; when the first outer diameter is greater than the second preset threshold, the winding tension of the tension roller is controlled to be a second winding tension; when the first preset threshold is less than the second preset threshold, the first winding tension is greater than the second winding tension.

Through the control method of the winding equipment provided in this application, the winding tension of the inner ring of the target roll is relatively large, which can reduce the interlayer gap of the inner ring of the target roll, making the adjacent layers of the inner ring of the target roll adhere more tightly. The tighter the adhesion between the adjacent layers of the inner ring of the target roll, the greater the pressure between the adjacent layers, and the greater the interlayer friction, thereby avoiding the deformation, flattening, or even collapse of the roll caused by interlayer slippage.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] For ease of storage and transportation, the strip material needs to be wound into rolls using a winding machine after processing. Because the roll material is cylindrical in shape and hollow inside, it will deform under the influence of gravity, and in severe cases, it may flatten or even collapse.

[0038] In existing technologies, there are two main methods to address the issues of coil deformation, flattening, and even collapse. Method one involves increasing the surface roughness of the strip material, thereby increasing the friction between adjacent layers and preventing slippage. Method two involves adding an extra sleeve to the inner ring of the coil to increase support and prevent deformation, flattening, or collapse; this sleeve is typically made of paper. However, Method one, by increasing the surface roughness of the strip material, imposes new process requirements on the grinding rollers in previous steps; Method two, by adding a sleeve, incurs additional costs.

[0039] To address the aforementioned problems, embodiments of this application provide a control method, apparatus, winding device, and readable storage medium for a winding equipment, which can increase the support strength of the inner ring of the winding material, thereby preventing deformation, flattening, or even collapse of the winding material caused by interlayer slippage. The embodiments provided in this application will be described in detail below with reference to the accompanying drawings.

[0040] Please refer to Figure 1 and Figure 2 ,in, Figure 2 The horizontal axis represents the first outer diameter D of the target roll material, and the vertical axis represents the winding tension F. A first aspect of this application provides a control method for a winding device, which includes a winding machine and a tension roller. The strip material passes sequentially through the tension roller and the winding machine to be wound into a roll material, including:

[0041] S1. Obtain the first outer diameter D of the target roll material, and wind the target roll material onto the reel of the winding machine;

[0042] S2. Control the winding tension F of the tension roller according to the first outer diameter D, wherein, when the first outer diameter D is less than or equal to the first preset threshold, the winding tension F of the tension roller is controlled to be the first winding tension F1; when the first outer diameter D is greater than the first preset threshold and less than or equal to the second preset threshold, the winding tension F of the tension roller is controlled to decrease from the first winding tension F1 to the second winding tension F2; when the first outer diameter D is greater than the second preset threshold, the winding tension F of the tension roller is controlled to be the second winding tension F2; when the first preset threshold is less than the second preset threshold, the first winding tension F1 is greater than the second winding tension F2.

[0043] Here, the first outer diameter D of the target roll material refers to the diameter of the outermost layer of the target roll material. It should be understood that as the winding machine's spool rotates continuously, the target strip material is continuously wound around, and the first outer diameter D continuously increases. Optionally, the first outer diameter D can be directly measured using a rangefinder, or it can be obtained by acquiring the number of layers of the roll material wound on the spool and calculating the first outer diameter D based on the number of layers, the thickness of the target strip material, and the diameter of the spool. For example, if the number of layers of the roll material wound on the spool is 10, the thickness of the target strip material is 0.9 mm, and the second outer diameter d of the spool is 508 mm, then the first outer diameter D is 10 × 2 × 0.9 + 508 = 526 mm.

[0044] The control method of the winding device in this application embodiment controls the winding tension F of the tension roller according to the first outer diameter D. When the first outer diameter D is less than or equal to a first preset threshold, the winding tension F is a first winding tension F1; when the first outer diameter D is greater than a second preset threshold, the winding tension F is a second winding tension F2. Since the first winding tension F1 is greater than the second winding tension F2, the winding tension F of the inner ring of the target roll is relatively large, which can reduce the interlayer gap of the inner ring of the target roll, making the adjacent layers of the inner ring of the target roll adhere more tightly. The tighter the adhesion between the adjacent layers of the inner ring of the target roll, the greater the pressure between the adjacent layers and the greater the interlayer friction, thereby preventing the target roll from slipping between layers, causing roll deformation, flattening, or even collapse.

[0045] In some optional embodiments, the second outer diameter of the winding machine's spool is d, the first preset threshold is (d+80mm) to (d+120mm), and the second preset threshold is (d+180mm) to (d+230mm). For example, if the second outer diameter d is 508mm, then the first preset threshold is 588mm to 628mm, and the second preset threshold is 688mm to 738mm. Specifically, the first preset threshold is 608mm, and the second preset threshold is 708mm. In this case, when the first outer diameter D of the roll is less than or equal to 608mm, the winding tension F is the first winding tension; when the first outer diameter D is greater than 608mm and less than or equal to 708mm, the winding tension F decreases from the first winding tension F1 to the second winding tension F2; and when the first outer diameter D is greater than 708mm, the winding tension F is the second winding tension F2.

[0046] In some alternative embodiments, controlling the reduction of the winding tension F of the tension roller from a first winding tension F1 to a second winding tension F2 includes:

[0047] The winding tension F of the control tension roller decreases from the first winding tension F1 to the second winding tension F2 at a first rate of change, and the first rate of change gradually increases with the increase of the first outer diameter D.

[0048] In these alternative embodiments, the first rate of change gradually increases. That is, as the winding tension F decreases from the first winding tension F1 to the second winding tension F2, the rate of decrease of the winding tension F becomes faster and faster, decreasing slowly at first and then rapidly. Compared to a scenario where the first rate of change remains constant with the increase of the first outer diameter D, the case where the first rate of change gradually increases with the increase of the first outer diameter D results in a larger winding tension F in the inner ring. This means there are more layers with a large winding tension F, which is more conducive to ensuring a tighter fit between adjacent layers in the inner ring of the target roll material. This increases interlayer friction, thereby preventing the target roll material from slipping between layers, which could cause deformation, flattening, or even collapse.

[0049] Please refer to Figure 3 In some optional embodiments, the tension roller 100 includes a first roller group 110 and a second roller group 120. The target strip 200 passes sequentially through the first roller group 110, the second roller group 120, and the winding machine. S2 includes:

[0050] The rotational speeds of the first roller group 110 and the second roller group 120 are controlled according to the first outer diameter D to control the winding tension F of the tension roller 100.

[0051] The winding tension F provided by the tension roller 100 is obtained through the speed difference between the first roller group 110 and the second roller group 120. The winding tension F is obtained by controlling the rotational speed of the second roller group 120 to be greater than that of the first roller group 110. The greater the speed difference between the first roller group 110 and the second roller group 120, the greater the winding tension F provided by the tension roller 100.

[0052] When the first outer diameter D is greater than a first preset threshold and less than or equal to a second preset threshold, the rotational speed of the first roller group 110 can be increased to reduce the speed difference between the first roller group 110 and the second roller group 120, or the rotational speed of the second roller group 120 can be decreased to reduce the speed difference between the first roller group 110 and the second roller group 120. Preferably, by controlling the rotational speed of the first roller group 110 to increase the speed difference between the first roller group 110 and the second roller group 120, both the winding tension F can be reduced and efficiency can be maintained.

[0053] For example, when the rotational speed of the first roller group 110 is a first speed and the rotational speed of the second roller group 120 is a second speed, the winding tension F provided by the tension roller 100 is a first winding tension F1, wherein the second speed is greater than the first speed. When the first outer diameter D is greater than a first preset threshold and less than or equal to a second preset threshold, the rotational speed of the first roller group 110 is controlled to increase from the first speed to a third speed, so that the winding tension F decreases to a second winding tension F2, wherein the third speed is greater than the first speed and less than the second speed.

[0054] Please refer to Figure 4 In some optional embodiments, before S1, the following steps are also included:

[0055] S3. Obtain the classification and thickness information of the target strip;

[0056] S4. Determine the preset take-up tension F corresponding to the target roll material according to the preset mapping relationship. The preset mapping relationship includes the mapping relationship of classification information, thickness information, and preset take-up tension F.

[0057] S5. Obtain the distance between the tension roller and the winding machine;

[0058] S6. Determine the first winding tension F1 and the second winding tension F2 based on the preset winding tension F, distance and thickness information. The second winding tension F2 is greater than or equal to the preset winding tension F.

[0059] The classification information and thickness information of the target strip can be entered manually or measured by a thickness gauge installed on the winding equipment. Preset mapping relationships can be pre-defined by process engineers and stored in the control system for direct retrieval. Each defined classification and thickness information corresponds to a defined preset winding tension F. The preset winding tension F is the minimum winding tension F that should be achieved when winding the target strip; if it is less than the preset winding tension F, the target roll is more likely to deform, flatten, or collapse.

[0060] To ensure efficiency, at least two winding machines should be installed. Once the roll material on one winding machine reaches the preset diameter, it must be unloaded, and the machine should be switched to another winding machine to continue winding. The distance between the winding machine and the tension roller varies.

[0061] It should be understood that the greater the distance between the tension roller and the winding machine, and the smaller the thickness of the target strip, the greater the winding tension F should be to prevent the target strip from deforming, flattening, or collapsing. Correspondingly, the first winding tension F1 and the second winding tension F2 should also be greater.

[0062] Specifically, S6 includes:

[0063] When the distance is greater than the third preset threshold and the thickness information is less than the fourth preset threshold, the ratio of the first winding tension F1 to the preset winding tension F is 2.0 to 2.4, and the second winding tension F2 is equal to the preset winding tension F.

[0064] When the distance is greater than the third preset threshold and the thickness information is greater than or equal to the fourth preset threshold, the ratio of the first winding tension F1 to the preset winding tension F is 1.3 to 1.7, and the second winding tension F2 is equal to the preset winding tension F.

[0065] When the distance is less than or equal to the third preset threshold and the thickness information is less than the fourth preset threshold, the ratio of the first winding tension F1 to the preset winding tension F is 2.0 to 2.4, and the second winding tension F2 is equal to the preset winding tension F.

[0066] When the distance is less than or equal to the third preset threshold and the thickness information is greater than or equal to the fourth preset threshold, the ratio of the first winding tension F1 to the preset winding tension F is 1.1 to 1.5, and the second winding tension F2 is equal to the preset winding tension F.

[0067] In these alternative embodiments, different first winding tensions F1 and second winding tensions F2 are set according to the thickness and classification information of the target strip and the specific relationship between the winding machine and the tension roller, to ensure that the two adjacent layers of the inner ring of the target roll are bonded tightly enough, increase the interlayer friction, and thus avoid the target roll from sliding between layers, causing the roll to deform, flatten, or even collapse.

[0068] Optionally, the third preset threshold is 12m to 15m, and the fourth preset threshold is 0.8mm to 1.0mm. For example, the third preset threshold is 14m, and the fourth preset threshold is 0.9mm. The winding equipment includes two winding machines, a first winding machine and a second winding machine. The distance from the first winding machine to the tension roller is 12m, and the distance from the second winding machine to the tension roller is 20m. The preset winding tension F corresponding to the target strip is F0. For the first winding machine, when the thickness of the target strip is less than 0.9mm, the first winding tension F1 is 2.2F0, and the second winding tension F2 is F0; when the thickness of the target strip is greater than or equal to 0.9mm, the first winding tension F1 is 1.3F0, and the second winding tension F2 is F0. For the second winding machine, when the target strip thickness is less than 0.9 mm, the first winding tension F1 is 2.2F0, and the second winding tension F2 is F0; when the target strip thickness is greater than or equal to 0.9 mm, the first winding tension F1 is 1.5F0, and the second winding tension F2 is F0. It should be understood that neither the first winding tension F1 nor the second winding tension F2 should exceed the maximum winding tension F of the winding equipment to avoid damage to the winding equipment.

[0069] Please refer to Figure 5A second aspect of this application provides a control device for controlling a winding device, the winding device including a winding machine and a tension roller. The control device includes a first acquisition module and a control module. The first acquisition module is used to acquire a first outer diameter of a target roll material, the target roll material being wound around the reel of the winding machine. The control module is used to control the winding tension of the tension roller according to the first outer diameter, wherein, when the first outer diameter is less than or equal to a first preset threshold, the winding tension of the tension roller is controlled to be a first winding tension; when the first outer diameter is greater than the first preset threshold and less than or equal to a second preset threshold, the winding tension of the tension roller is controlled to decrease from the first winding tension to a second winding tension; when the first outer diameter is greater than the second preset threshold, the winding tension of the tension roller is controlled to be a second winding tension; when the first preset threshold is less than the second preset threshold, the first winding tension is greater than the second winding tension.
