For convenience in storage and transportation, the strip needs to be coiled into a coiled material by coiling equipment after the strip processing is completed. Because the coiled material is cylindrical in shape and hollow in the interior, the coiled material can deform under the action of gravity, and the phenomena of flat rolling and even collapse can occur seriously.
In the prior art, measures for solving the problems of coiled material deformation, flat rolling and even collapsing mainly comprise two modes. The first mode is to increase the roughness of the surface of the strip, so that the friction between two adjacent layers of the coiled material is increased, and the sliding between the layers of the coiled material is prevented. The second mode is that a sleeve is additionally arranged on the inner ring of the coiled material, so that supporting force is increased, the coiled material is prevented from deforming, flattening and even collapsing, and the sleeve is generally a paper sleeve. However, in the first mode, the roughness of the surface of the strip is increased, so that new process demands are made on the grinding roller in the previous working procedure; the addition of a sleeve in the second mode requires additional costs.
In order to solve the above problems, embodiments of the present application provide a control method and apparatus for a winding apparatus, and a readable storage medium, which can increase the supporting strength of an inner coil of a coil, so as to avoid deformation, flat coil, and even collapse of the coil caused by sliding between coil layers. Various embodiments provided herein will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, wherein an abscissa in fig. 2 is a first outer diameter D of a target coil, and an ordinate is a winding tension F, an embodiment of a first aspect of the present application provides a control method of a winding apparatus, where the winding apparatus includes a winding machine and a tension roller, and a strip sequentially passes through the tension roller and the winding machine to be wound into a coil, including:
s1, acquiring a first outer diameter D of a target coiled material, wherein the target coiled material is wound on a reel of a coiling machine;
s2, controlling the coiling tension F of the tension roller according to the first outer diameter D, wherein the coiling tension F of the tension roller is controlled to be the first coiling tension F under the condition that the first outer diameter D is smaller than or equal to a first preset threshold value 1 The method comprises the steps of carrying out a first treatment on the surface of the Controlling the winding tension F of the tension roller from the first winding tension F in the case that the first outer diameter D is larger than a first preset threshold value and smaller than or equal to a second preset threshold value 1 Reduced to a second winding tension F 2 The method comprises the steps of carrying out a first treatment on the surface of the Controlling the winding tension F of the tension roller to be the second winding tension F under the condition that the first outer diameter D is larger than a second preset threshold value 2 The method comprises the steps of carrying out a first treatment on the surface of the The first preset threshold value is smaller than the second preset threshold value, and the first coiling tension F 1 Greater than the second winding tension F 2 。
Where the first outer diameter D of the target coil refers to the diameter of the outermost turn of the target coil, it will be appreciated that the reel of the coiler continues to rotate and the target strip continues to wind with it, the first outer diameter D increasing. Alternatively, the first outer diameter D may be obtained by direct measurement according to a distance meter, or may be obtained by obtaining the number of layers of the coiled material wound on the reel, and calculating the first outer diameter D according to the number of layers of the coiled material, the thickness of the target strip, and the diameter of the reel. Illustratively, in the case where the number of layers of the coil wound on the reel is 10, the thickness of the target strip is 0.9mm, and the second outer diameter D of the reel is 508mm, the first outer diameter D is 10×2×0.9+508=526 mm.
According to the control method of the coiling equipment, the coiling tension F of the tension roller is controlled according to the first outer diameter D, and the coiling tension F is the first coiling tension F when the first outer diameter D is smaller than or equal to the first preset threshold value 1 In the case where the first outer diameter D is greater than the second preset threshold value, the winding tension F is the second winding tension F 2 . And a first winding tension F 1 Greater than the second winding tension F 2 That is to say, the coiling tension F of the inner ring of the target coiled material is relatively large, and the interlayer gap of the inner ring of the target coiled material can be reduced, so that the adjacent two layers of the inner ring of the target coiled material are tightly attached. The closer the inner ring of the target coiled material is attached between two adjacent layers, the larger the pressure between the two adjacent layers is, and the larger the interlayer friction force is, so that the deformation, flat rolling and even collapse of the coiled material caused by interlayer sliding of the target coiled material are avoided.
In some alternative embodiments, the second outer diameter of the reel spool of the coiler is d, the first preset threshold is (d+80 mm) to (d+120 mm), and the second preset threshold is (d+180 mm) to (d+230 mm). Illustratively, the second outer diameter d is 508mm, then the first predetermined threshold is 588mm to 628mm and the second predetermined threshold is 688mm to 738mm. Specifically, the first preset threshold is 608mm, and the second preset threshold is 708mm. At this time, the winding tension F is a first winding tension when the first outer diameter D of the coil is 608mm or less, and the winding tension F is a second winding tension F when the first outer diameter D is 608mm or more and 708mm or less 1 Reduced to a second winding tension F 2 In the case that the first outer diameter D is larger than 708mmIn the case where the winding tension F is the second winding tension F 2 。
In some alternative embodiments, the winding tension F of the tension roller is controlled from the first winding tension F 1 Reduced to a second winding tension F 2 Comprising:
controlling the winding tension F of the tension roller from the first winding tension F at a first rate of change 1 Reduced to a second winding tension F 2 The first rate of change increases progressively with increasing first outer diameter D.
In these alternative embodiments, the first rate of change is increased stepwise, that is to say the winding tension F is increased from the first winding tension F 1 Reduced to a second winding tension F 2 In the process, the winding tension F is reduced more and more rapidly, and is reduced slowly and then is reduced rapidly. Compared with the condition that the first change rate is constant along with the increase of the first outer diameter D, the first change rate is gradually increased along with the increase of the first outer diameter D, the coiling tension F of the inner ring is larger, namely the number of layers of the large coiling tension F is more, the close fit between two adjacent layers of the inner ring of the target coiled material is more facilitated, the interlayer friction force is increased, and therefore the deformation, flat rolling and even collapse of the coiled material caused by interlayer sliding of the target coiled material are avoided.
Referring to fig. 3, in some alternative embodiments, the tension roller 100 includes a first roller set 110 and a second roller set 120, and the target strip 200 sequentially passes through the first roller set 110, the second roller set 120, and the coiler, S2 includes:
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.
The winding tension F provided by the tension roller 100 is obtained by a speed difference between the first roller group 110 and the second roller group 120, and the winding tension F is obtained by controlling the rotation speed of the second roller group 120 to be larger than that of the first roller group 110. The larger the speed difference between the first roller group 110 and the second roller group 120, the larger the winding tension F provided by the tension roller 100.
In the case where the first outer diameter D is greater than the first preset threshold value and less than or equal to the second preset threshold value, the rotational speed of the first roller group 110 may be controlled to 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 may be controlled to be reduced 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 be increased to reduce the speed difference between the first roller group 110 and the second roller group 120, both the winding tension F and the efficiency can be ensured.
The first set of rollers 110 is exemplified by a first speed, and the second set of rollers 120 is exemplified by a second speed, wherein the winding tension F provided by the tension roller 100 is the first winding tension F 1 Wherein the second speed is greater than the first speed. In the case where the first outer diameter D is greater than the first preset threshold value and less than or equal to the second preset threshold value, the rotational speed of the first roller group 110 is controlled to increase from the first speed to the third speed so that the winding tension F is reduced to the second winding tension F 2 Wherein the third speed is greater than the first speed and less than the second speed.
Referring to fig. 4, in some alternative embodiments, before S1, the method further includes:
s3, obtaining classification information and thickness information of the target strip;
s4, determining a preset coiling tension F corresponding to the target coiled material according to a preset mapping relation, wherein the preset mapping relation comprises mapping relation of classification information, thickness information and the preset coiling tension F;
s5, obtaining the distance between the tension roller and the coiling machine;
s6, determining a first coiling tension F according to the preset coiling tension F, the distance and the thickness information 1 And a second winding tension F 2 Second winding tension F 2 Is greater than or equal to the preset winding tension F.
The classification information of the target strip can be manually input, and the thickness information can be manually input or measured by a thickness gauge arranged on coiling equipment. The preset mapping relation can be preset by a craftsman and stored in a control system to be directly called. The determined classification information and thickness information correspond to a determined preset winding tension F. The preset coiling tension F is the minimum coiling tension F which is required to be achieved when the target strip is coiled and is smaller than the preset coiling tension F, and the possibility of deformation, flat coiling or collapse of the target coiled material is high.
In order to ensure the efficiency, at least two coiling machines are arranged, after the coiled material on one coiling machine reaches the preset diameter, the coiled material is required to be taken down, and the coiling machine is switched to other coiling machines to continue coiling. The distances between the different winders and the tension roller are different.
It will be appreciated that the greater the distance between the tension roller and the coiler, the smaller the thickness of the target strip, and that in order to prevent deformation, flat or collapse of the target coil, the greater the coiling tension F should be, the corresponding first coiling tension F 1 And a second winding tension F 2 The larger should be.
Specifically, S6 includes:
in the case that the distance is greater than the third preset threshold value and the thickness information is less than the fourth preset threshold value, the first winding tension F 1 The ratio of the second winding tension F to the preset winding tension F is 2.0-2.4 2 Is equal to the preset winding tension F;
in the case where the distance is greater than the third preset threshold value and the thickness information is greater than or equal to the fourth preset threshold value, the first winding tension F 1 The ratio of the second winding tension F to the preset winding tension F is 1.3-1.7 2 Is equal to the preset winding tension F;
in the case where the distance is less than or equal to the third preset threshold value and the thickness information is less than the fourth preset threshold value, the first winding tension F 1 The ratio of the second winding tension F to the preset winding tension F is 2.0-2.4 2 Is equal to the preset winding tension F;
in the case where the distance is less than or equal to the third preset threshold value and the thickness information is greater than or equal to the fourth preset threshold value, the first winding tension F 1 The ratio of the second winding tension F to the preset winding tension F is 1.1-1.5 2 Equal to the preset winding tension F.
In these alternative embodiments, the different first coiling tensions F are set according to the thickness information and the classification information of the target strip and the specifics between the coiler and the tension roller 1 And a second winding tension F 2 Ensuring the close enough adhesion between two adjacent layers of the inner ring of the target coiled material, increasing the interlayer friction force and avoiding the target coiled materialThe sliding between the layers causes deformation, flat rolling and even collapse of the coiled material.
Optionally, the third preset threshold is 12-15 m, and the fourth preset threshold is 0.8-1.0 mm. Illustratively, the third predetermined threshold is 14m and the fourth predetermined threshold is 0.9mm. The coiling equipment comprises two coiling machines, namely a first coiling machine and a second coiling machine, wherein the distance from the first coiling machine to the tension roller is 12m, the distance from the second coiling machine to the tension roller is 20m, and the preset coiling tension F corresponding to the target strip is F 0 . For the first coiler, in the case where the thickness of the target strip is less than 0.9mm, a first coiling tension F 1 Is 2.2F 0 Second winding tension F 2 Is F 0 The method comprises the steps of carrying out a first treatment on the surface of the In the case where the thickness of the target strip is greater than or equal to 0.9mm, a first winding tension F 1 1.3F 0 Second winding tension F 2 Is F 0 . For the second coiler, in the case where the thickness of the target strip is less than 0.9mm, the first coiling tension F 1 Is 2.2F 0 Second winding tension F 2 Is F 0 The method comprises the steps of carrying out a first treatment on the surface of the In the case where the thickness of the target strip is greater than or equal to 0.9mm, a first winding tension F 1 1.5F 0 Second winding tension F 2 Is F 0 . Of course, it should be appreciated that the first winding tension F 1 And a second winding tension F 2 Should not be greater than the maximum winding tension F of the winding device, avoiding damage to the winding device.
