[0001] The present invention relates to the technical field of spinning, and in particular to a yarn doubling method, a control device of a yarn doubling device, a storage medium and a yarn doubling device. Background Art

[0002] At present, in the relevant technology, when using a winding machine to wind the yarn, because the winding angle of the small diameter section of the precision winding is large, the density of the inner layer of the yarn tube is smaller than that of the outer layer. At the same time, the differential function is enabled, and the density of the outer edge of the yarn tube is even smaller and is not enough to support the pressure of the outer layer of yarn, which can easily cause the problem of mesh wire jumping. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a yarn doubling method.

[0005] A second aspect of the present invention provides a control device for a yarn doubling device.

[0006] A third aspect of the present invention provides a control device for a yarn doubling device.

[0007] A fourth aspect of the present invention provides a readable storage medium.

[0008] A fifth aspect of the present invention provides a yarn doubling device.

[0009] In view of this, the first aspect of the present invention provides a yarn doubling method for a yarn doubling machine, the yarn doubling machine includes a drum and a wire guide device, the yarn doubling method includes: controlling the rotation of the drum; controlling the wire guide device to reciprocate along the axial direction of the drum, the wire guide device cooperates with the drum to drive the yarn to be wound around the drum; according to the outer diameter of the drum wound with the yarn, the reversing point of the wire guide device is obtained; according to the reversing point, the reversing of the wire guide device is controlled.

[0010] In this technical solution, a doubling method is used on a doubling machine to enable the doubling machine to wind yarn, thereby achieving a doubling operation. The doubling machine includes a reel and a wire guide device. The doubling machine is also provided with a frame, and the reel and the wire guide device are mounted on the frame to facilitate the installation and fixation of the reel and the wire guide device. The doubling method includes: controlling the rotation of the reel, rotating the reel so that the reel can wind the yarn, thereby facilitating the winding of the yarn onto the reel. The wire guide device is controlled to reciprocate along the axis of the drum. The wire guide device cooperates with the drum to drive the yarn to be wound around the drum. Since the wire guide device reciprocates along the axis of the drum and the yarn is threaded through the wire guide device, the wire guide device can also drive the yarn to reciprocate. When the drum rotates, the yarn can be wound on the drum from one end to the other end. Since the yarn reciprocates, the yarn changes its direction of movement when it is wound on one end of the drum and is wound on the drum. According to the outer diameter of the drum on which the yarn is wound, the reversal point of the wire guide device is obtained. That is, during the winding process, the outer diameter of the drum on which the yarn is wound continuously increases. Then, the reversal point of the wire guide device can be changed according to the outer diameter of the drum on which the yarn is wound. According to the reversal point, the wire guide device is controlled to reverse, thereby achieving reversal of the wire guide device at the reversal point, thereby changing the reversal position of the yarn during the winding process. If the reversing point of the wire guide device is changed at the beginning of the rotation of the drum, due to the large winding angle of the small diameter section of the precision winding, the density of the inner layer of the yarn drum is smaller than that of the outer layer, and the density of the outer edge of the yarn drum is even smaller and cannot support the pressure of the outer layer of yarn, which is similar to an unstable foundation and can easily cause the problem of mesh wire jump. In the present application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the amount of yarn accumulated on the outer edge of the yarn drum, and changing the pressure of the outer layer of the inner layer of the yarn drum due to the smaller winding angle to the pressure of a certain area on both sides of the yarn drum, which can effectively reduce the deformation of the yarn drum and ensure that the yarn drum can be smoothly unwound in the subsequent doubling process. Moreover, compared with the method of changing the reversing position at the beginning of winding, the density of winding in the early stage of winding can also be guaranteed, which can effectively solve the problems of yarn drum deformation and mesh wire jump.

[0011] In addition, the yarn doubling method in the above technical solution provided by the present invention may also have the following additional technical features:

[0012] In one technical solution of the present invention, the reversing point of the wire guide device is obtained according to the outer diameter of the drum wound with the yarn, including: when the outer diameter of the drum wound with the yarn reaches a first preset outer diameter, the position of the reversing point is obtained.

[0013] In this technical solution, the reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, including obtaining the position of the reversing point when the outer diameter of the drum on which the yarn is wound reaches a first preset outer diameter. Since the winding angle decreases with the increase of the diameter during the process of the drum winding the yarn, the yarn turns slowly at the reversing points on both sides, and the yarn is excessively accumulated, causing the edge of the yarn drum to be compressed and deformed. Therefore, when the diameter reaches the first preset outer diameter, that is, when the edge of the yarn drum is compressed and begins to deform, the position of the reversing point is obtained, thereby avoiding excessive accumulation of yarn at the reversing points on both sides, and changing the pressure of the outer layer yarn on the outer point of the inner layer yarn drum due to the smaller winding angle into the pressure of a certain area on both sides of the yarn drum, which can effectively reduce the deformation of the yarn drum.

[0014] In one technical solution of the present invention, the distance between the reversing point and the end of the reel is greater than or equal to 2 mm and less than or equal to 20 mm.

[0015] In this technical solution, the distance between the reversing point and the end of the drum is greater than or equal to 2 mm and less than or equal to 20 mm. By changing the distance between the reversing point and the end of the drum, the reversing point of the wire guide device can be adjusted. By setting the distance between the reversing point and the end of the drum to 2 mm to 20 mm, the wire guide device can be avoided from reversing at the position of the end of the yarn drum, thereby effectively solving the problem of excessive accumulation of yarn at the reversing points on both sides, thereby avoiding deformation of the end of the yarn drum.

[0016] In one technical solution of the present invention, the reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, specifically including: obtaining the reversing point of the wire guide device according to the first outer diameter of the drum on which the yarn is wound; obtaining the second outer diameter of the drum on which the yarn is wound again after a preset time interval, and adjusting the reversing point according to the second outer diameter.

[0017] In this technical solution, the reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, specifically including: obtaining the reversing point of the wire guide device according to the first outer diameter of the drum on which the yarn is wound, obtaining the reversing point of the wire guide device according to the first outer diameter, and changing the reversing point of the wire guide device, thereby avoiding the yarn from piling up at the end of the drum and causing the yarn to deform. At intervals of a preset time, the second outer diameter of the drum on which the yarn is wound is obtained again, and the reversing point is adjusted according to the second outer diameter, that is, at intervals of a preset time, the reversing point of the wire guide device is obtained according to the second outer diameter, and the reversing point of the wire guide device can be adjusted. Therefore, during the process of winding the yarn on the drum, the reversing point can be adjusted at intervals of a preset time, thereby avoiding the yarn from piling up again at the end of the drum and causing the drum to deform after the first adjustment of the reversing point.

[0018] In one technical solution of the present invention, before obtaining the second outer diameter of the drum wound with the yarn, the yarn doubling method further comprises: controlling the yarn guide device to reverse at the end of the drum;

[0019] In this technical solution, before obtaining the second outer diameter of the reel wound with the yarn, the yarn doubling method also includes: controlling the wire guide device to reverse at the end of the reel. Since there is a certain distance between the first reversing point of the wire guide device and the end of the yarn drum, before adjusting the reversing point of the wire guide device for the second time, the wire guide device can be controlled to reverse again from the position of the end of the yarn drum, thereby ensuring the width of the yarn drum after winding the yarn.

[0020] In a technical solution of the present invention, the doubling machine further includes a tensioner, and the number of yarns is multiple. The doubling method further includes: controlling the tensioner to adjust the tension of the multiple yarns.

[0021] In this technical solution, the doubling machine further includes a tensioner, and the number of yarns is multiple, so that the doubling machine can doubling the multiple yarns. The doubling method further includes: controlling the tensioner to adjust the tension of the multiple yarns so that after the reel winds the yarn, the density of the yarn can be maintained after winding, and the yarn is prevented from becoming loose after winding, which is not conducive to yarn winding.

[0022] A second aspect of the present invention provides a control device for a yarn doubling device, the yarn doubling device comprising a winding drum and a yarn guide device, the control device comprising: a drive unit, a capture unit, and an adjustment unit. The drive unit is configured to drive the yarn guide device to cooperate with the winding drum to drive the yarn to be wound around the winding drum; the capture unit is configured to determine the outer diameter of the winding drum on which the yarn is wound; and the adjustment unit is configured to control the reversal of the yarn guide device based on the outer diameter of the winding drum on which the yarn is wound.

[0023] In this technical solution, the control device includes a drive unit, a capture unit, and an adjustment unit. The drive unit is used to drive the wire guide device to cooperate with the drum to drive the yarn to be wound around the drum. The capture unit is used to adjust the outer diameter of the drum on which the yarn is wound. The adjustment unit is used to control the direction of the wire guide device according to the outer diameter of the drum on which the yarn is wound. Specifically, by rotating the drum, the drum can wind the yarn, thereby facilitating the winding of the yarn onto the drum. The wire guide device is controlled to reciprocate along the axis of the drum. The wire guide device and the drum cooperate to drive the yarn to be wound onto the drum. Since the wire guide device reciprocates along the axis of the drum and the yarn is threaded through the wire guide device, the wire guide device can also drive the yarn to reciprocate. As the drum rotates, the yarn is wound onto the drum from one end to the other. Since the yarn reciprocates, the yarn changes direction when it is wound onto one end of the drum and is wound onto the drum. The reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, that is, during the winding process, the outer diameter of the drum on which the yarn is wound is continuously increasing, and then the reversing point of the wire guide device can be changed according to the outer diameter of the drum on which the yarn is wound. According to the reversing point, the reversal of the wire guide device is controlled, thereby realizing the reversal of the wire guide device at the reversing point, thereby changing the reversing position of the yarn during the winding process. If the reversing point of the wire guide device is changed at the beginning of the rotation of the drum, due to the large winding angle of the small diameter section of the precision winding, the density of the inner layer of the yarn drum is smaller than that of the outer layer, and the density of the outer edge of the yarn drum is even smaller and cannot support the pressure of the outer layer of yarn, which is similar to an unstable foundation and can easily cause the problem of mesh wire jump. In the present application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the amount of yarn accumulated on the outer edge of the yarn drum, and changing the pressure of the outer layer of the inner layer of the yarn drum due to the smaller winding angle to the pressure of a certain area on both sides of the yarn drum, which can effectively reduce the deformation of the yarn drum and ensure that the yarn drum can be smoothly unwound in the subsequent doubling process. Moreover, compared with the method of changing the reversing position at the beginning of winding, the density of winding in the early stage of winding can also be guaranteed, which can effectively solve the problems of yarn drum deformation and mesh wire jump.

[0024] The third aspect of the present invention provides a control device for a yarn doubling device, comprising a memory and a processor, wherein the memory stores programs or instructions that can be run on the processor, and when the programs or instructions are executed by the processor, the steps of the yarn doubling method in any of the above-mentioned technical solutions are implemented. Therefore, the control device of the yarn doubling device has all the beneficial effects of the yarn doubling method, which will not be repeated here.

[0025] The fourth aspect of the present invention provides a readable storage medium on which a program or instruction is stored. When the program or instruction is executed by the processor, the steps of the yarn doubling method in any of the above-mentioned technical solutions are implemented. Therefore, the readable storage medium has all the beneficial effects of the yarn doubling method, which will not be repeated here.

[0026] The fifth aspect of the present invention provides a yarn doubling device, comprising: the control device of the yarn doubling device in the above technical solution; or the control device of the yarn doubling device in the above technical solution; or the readable storage medium in the above technical solution. Therefore, the yarn doubling device has all the beneficial effects of the control device and the readable storage medium of the yarn doubling device, which will not be repeated here.

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] Refer to the following Figures 1 to 5 The present invention describes a yarn doubling method, a control device for a yarn doubling device, a storage medium, and a yarn doubling device according to some embodiments of the present invention.

[0037] In one embodiment of the present invention, a doubling method is provided for a doubling machine, the doubling machine comprising a winding drum and a wire guide device, such as Figure 1 As shown, the yarn doubling method includes:

[0038] S102, controlling the reel to rotate;

[0039] S104, controlling the yarn guide device to reciprocate along the axis of the drum, wherein the yarn guide device cooperates with the drum to drive the yarn to be wound around the drum;

[0040] S106, obtaining a reversing point of the yarn guide device according to the outer diameter of the drum wound with the yarn;

[0041] S108, controlling the reversal of the wire guide device according to the reversal point.

[0042] In this embodiment, a doubling method is used in a doubling machine to enable the doubling machine to wind yarn, thereby achieving a doubling operation. The doubling machine includes a reel and a wire guide device. The doubling machine is also provided with a frame, and the reel and wire guide device are both mounted on the frame to facilitate the installation and fixation of the reel and the wire guide device. The doubling method includes: controlling the reel to rotate, so that the reel can wind the yarn by rotating the reel, thereby facilitating the winding of the yarn onto the reel. Controlling the wire guide device to reciprocate along the axis of the reel. The wire guide device cooperates with the reel to drive the yarn to be wound onto the reel. Since the wire guide device reciprocates along the axis of the reel and the yarn is threaded through the wire guide device, the wire guide device can also drive the yarn to reciprocate. When the reel rotates, the yarn can be wound onto the reel from one end to the other end. Since the yarn reciprocates, the yarn changes its direction of movement when it is wound onto one end of the reel and is wound onto the reel. The reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, that is, during the winding process, the outer diameter of the drum on which the yarn is wound is continuously increasing, and then the reversing point of the wire guide device can be changed according to the outer diameter of the drum on which the yarn is wound. According to the reversing point, the reversal of the wire guide device is controlled, thereby realizing the reversal of the wire guide device at the reversing point, thereby changing the reversing position of the yarn during the winding process. If the reversing point of the wire guide device is changed at the beginning of the rotation of the drum, due to the large winding angle of the small diameter section of the precision winding, the density of the inner layer of the yarn drum is smaller than that of the outer layer, and the density of the outer edge of the yarn drum is even smaller and cannot support the pressure of the outer layer of yarn, which is similar to an unstable foundation and can easily cause the problem of mesh wire jump. In the present application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the amount of yarn accumulated on the outer edge of the yarn drum, and changing the pressure of the outer layer of the inner layer of the yarn drum due to the smaller winding angle to the pressure of a certain area on both sides of the yarn drum, which can effectively reduce the deformation of the yarn drum and ensure that the yarn drum can be smoothly unwound in the subsequent doubling process. Moreover, compared with the method of changing the reversing position at the beginning of winding, the density of winding in the early stage of winding can also be guaranteed, which can effectively solve the problems of yarn drum deformation and mesh wire jump.

[0043] Specifically, in the process of yarn doubling, the bobbin winding equipment usually adopts a lateral differential function. The lateral differential function changes the reversing position of the wire guide device to solve the problem of hard edges of the yarn bobbin caused by slow lateral reversing. Generally, if the process setting differential amplitude is not equal to 0, that is, the entire winding process from empty bobbin to full bobbin, the differential function is effective. However, in the actual yarn doubling and winding process, because the winding angle of the small diameter section of the precision winding is large, the density of the inner layer of the yarn bobbin is smaller than that of the outer layer. At the same time, the differential function is enabled, and the density of the outer edge of the yarn bobbin is even smaller and is not enough to support the pressure of the outer yarn. It is similar to a weak foundation, which can easily cause the problem of mesh wire skipping. Therefore, this application adopts the method of winding to a certain diameter and then enabling the lateral differential function to effectively solve the problems of yarn bobbin deformation and mesh wire skipping.

[0044] Specifically, there are three winding methods for yarn bobbin winding: random winding, precision winding and digital winding. The winding angle of random winding is constant, the yarn arrangement is random, the winding gap is large, and the yarn bobbin density is minimum; digital winding is layered precision winding, and different diameters use different winding ratios. The winding angle variation range is small, and the yarns are arranged regularly. The gaps between adjacent yarns can be controlled by selecting a suitable winding ratio, and the package density is at least 20% higher than that of random winding; precision winding uses a fixed winding ratio, and a special winding ratio can be selected according to the thickness of the yarn to achieve tight and precise winding of the yarn, which minimizes the gaps between adjacent yarns and increases the yarn bobbin density by at least 5% compared to digital winding; precision winding machines generally use a precision winding process with a fixed winding ratio. In order to increase the package density, it is necessary to select a winding ratio close to the traverse reversing point to ensure The yarns are arranged neatly and tightly; however, as the package diameter increases, the winding angle of precision winding decreases, which means that the yarn turns slowly at the reversing point when winding, resulting in excessive accumulation of yarn at the maximum travel range on both sides of the yarn tube. At the same time, the back pressure and winding tension used for yarn doubling are relatively large, and the outermost side of the yarn tube is compressed into a bulge shape. The deformed yarn tube can easily rub against the tank body in the doubling yarn tank, causing yarn breakage, which greatly affects the efficiency of the subsequent doubling process. In this application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the amount of yarn accumulated on the outer edge of the yarn tube, and changing the pressure of the outer yarn on the outer point of the inner yarn tube due to the smaller winding angle into pressure on a certain area on both sides of the yarn tube, which can effectively reduce the deformation of the yarn tube and ensure that the yarn tube can be smoothly unwound in the subsequent doubling process.

[0045] Specifically, precision winding machines generally adopt a precision winding form with a fixed winding ratio. In order to increase the density of the yarn bobbin, the winding ratio of the precision winding can be increased in theory, that is, the number of turns of the single-layer yarn can be increased. However, in view of the characteristics of precision winding, as the diameter increases, the winding angle decreases, the yarn turns slowly at the reversing points on both sides, and the yarn is excessively accumulated, causing the edge of the yarn bobbin to be compressed and deformed. In the two-for-one twisting yarn tank, the yarn breaks when the yarn bobbin contacts the tank body during unwinding, affecting the unwinding efficiency. In this application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the number of yarns accumulated on the outer edge of the yarn bobbin, and changing the pressure of the outer layer yarn on the outer point of the inner layer yarn bobbin due to the smaller winding angle into the pressure of a certain area on both sides of the yarn bobbin, which can effectively reduce the deformation of the yarn bobbin and ensure that the yarn bobbin can be smoothly unwound in the subsequent two-for-one twisting process.

[0046] This embodiment provides a yarn doubling method, such as Figure 2 As shown, the yarn doubling method further includes:

[0047] S202, controlling the reel to rotate;

[0048] S204, controlling the wire guide device to reciprocate along the axis of the drum, wherein the wire guide device cooperates with the drum to drive the yarn to be wound around the drum;

[0049] S206, when the outer diameter of the drum wound with the yarn reaches a first preset outer diameter, obtaining the position of the reversal point;

[0050] S208, controlling the reversal of the wire guide device according to the reversal point.

[0051] In this embodiment, the reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, including obtaining the position of the reversing point when the outer diameter of the drum on which the yarn is wound reaches a first preset outer diameter. Since the winding angle decreases as the diameter increases during the process of the drum winding the yarn, the yarn turns slowly at the reversing points on both sides, and the yarn accumulates too much, causing the edge of the yarn drum to be compressed and deformed. Therefore, when the diameter reaches the first preset outer diameter, that is, when the edge of the yarn drum begins to be compressed and deformed, the position of the reversing point is obtained, thereby avoiding the yarn on both sides

[0052] Too many reversing points are accumulated, and the pressure of the outer yarn on the outer point of the inner yarn tube due to the smaller winding angle is changed by 5% to the pressure of a certain area on both sides of the yarn tube, which can effectively reduce the deformation of the yarn tube.

[0053] This embodiment provides a yarn doubling method. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0054] The distance between the reversing point and the end of the reel is greater than or equal to 2 mm and less than or equal to 20 mm.

[0055] In this embodiment, the distance between the reversing point and the end of the reel is greater than or equal to 2 mm and less than or equal to 20 mm. By changing the distance between the reversing point and the end of the reel, the reversing point can be adjusted.

[0056] The reversing point of the wire guide device is adjusted. By setting the distance between the reversing point and the end of the drum to 2mm to 20mm, the wire guide device can be prevented from reversing at the end of the yarn drum, thereby effectively solving the problem of excessive accumulation of yarn at the reversing points on both sides, thereby avoiding deformation of the end of the yarn drum.

[0057] 5 This embodiment provides a yarn doubling method, such as Figure 3 As shown, the yarn doubling method further includes:

[0058] S302, controlling the reel to rotate;

[0059] S304, controlling the yarn guide device to reciprocate along the axis of the drum, wherein the yarn guide device cooperates with the drum to drive the yarn to be wound around the drum;

[0060] S306, obtaining a reversal point of the yarn guide device based on a first outer diameter of the drum on which the yarn is wound; 0S308, after a preset time interval, obtaining a second outer diameter of the drum on which the yarn is wound again, and adjusting the reversal point based on the second outer diameter;

[0061] S310, controlling the reversal of the wire guide device according to the reversal point.

[0062] In this embodiment, the reversing direction of the yarn guide device is obtained according to the outer diameter of the drum on which the yarn is wound.

[0063] The point position specifically includes: obtaining the 5-way point position of the wire guide device according to the first outer diameter of the reel wound with the yarn, obtaining the reversing point position of the wire guide device according to the first outer diameter, and the reversing point position of the wire guide device can be adjusted.

[0064] The yarn is prevented from piling up at the end of the bobbin and causing yarn deformation.

[0065] At intervals of preset time, the second outer diameter of the drum on which the yarn is wound is obtained again, and the reversing point is adjusted according to the second outer diameter. That is, at intervals of preset time, the reversing point of the wire guide device is obtained according to the second outer diameter, and the reversing point of the wire guide device can be adjusted. Therefore, during the process of winding the yarn on the drum, the reversing point can be adjusted at intervals of preset time to avoid the yarn piling up at the end of the drum again after the first adjustment of the reversing point, causing deformation of the drum.

[0066] This embodiment provides a yarn doubling method, such as Figure 4 As shown, the yarn doubling method further includes:

[0067] S402, controlling the reel to rotate;

[0068] S404, controlling the yarn guide device to reciprocate along the axis of the drum, wherein the yarn guide device cooperates with the drum to drive the yarn to be wound around the drum;

[0069] S406, obtaining a reversing point of the yarn guide device according to a first outer diameter of the drum wound with the yarn;

[0070] S408, controlling the wire guide device to reverse at the end of the reel;

[0071] S410, after a preset time interval, obtaining the second outer diameter of the drum wound with the yarn again, and adjusting the reversing point according to the second outer diameter;

[0072] S412, controlling the reversal of the wire guide device according to the reversal point.

[0073] In this embodiment, before obtaining the second outer diameter of the drum wound with the yarn, the yarn winding method also includes: controlling the wire guide device to reverse at the end of the drum. Since there is a certain distance between the first reversing point of the wire guide device and the end of the yarn drum, before adjusting the reversing point of the wire guide device for the second time, the wire guide device can be controlled to reverse again from the position of the end of the yarn drum, thereby ensuring the width of the yarn drum after winding the yarn.

[0074] This embodiment provides a yarn doubling method, such as Figure 5 As shown, the yarn doubling method further includes:

[0075] S502, controlling the tensioner to adjust the tension of the plurality of yarns;

[0076] S504, controlling the reel to rotate;

[0077] S506, controlling the yarn guide device to reciprocate along the axis of the drum, wherein the yarn guide device cooperates with the drum to drive the yarn to be wound around the drum;

[0078] S508, obtaining a reversing point of the yarn guide device according to the outer diameter of the drum wound with the yarn;

[0079] S510, controlling the reversal of the wire guide device according to the reversal point.

[0080] In this embodiment, the doubling machine further includes a tensioner, and the number of yarns is multiple, so that the doubling machine can doubling the multiple yarns. The doubling method further includes: controlling the tensioner to adjust the tension of the multiple yarns so that after the reel winds the yarn, the density of the yarn can be maintained after winding, and the yarn is prevented from becoming loose after winding, which is not conducive to yarn winding.

[0081] In one embodiment of the present invention, a control device for a yarn doubling device is provided. The yarn doubling device includes a winding drum and a yarn guide device. The control device includes a drive unit, a capture unit, and an adjustment unit. The drive unit is used to drive the yarn guide device to cooperate with the winding drum to drive the yarn to be wound around the winding drum; the capture unit is used to determine the outer diameter of the winding drum on which the yarn is wound; and the adjustment unit is used to control the reversal of the yarn guide device based on the outer diameter of the winding drum on which the yarn is wound.

[0082] In this embodiment, the control device includes a drive unit, a capture unit, and an adjustment unit. The drive unit is used to drive the wire guide device to cooperate with the drum to drive the yarn to be wound around the drum. The capture unit is used to adjust the outer diameter of the drum on which the yarn is wound. The adjustment unit is used to control the direction of the wire guide device according to the outer diameter of the drum on which the yarn is wound. Specifically, by rotating the drum, the drum can wind the yarn, thereby facilitating the winding of the yarn onto the drum. The wire guide device is controlled to reciprocate along the axis of the drum. The wire guide device cooperates with the drum to drive the yarn to be wound onto the drum. Since the wire guide device reciprocates along the axis of the drum and the yarn is threaded through the wire guide device, the wire guide device can also drive the yarn to reciprocate. As the drum rotates, the yarn is wound onto the drum from one end to the other. Since the yarn reciprocates, the yarn changes direction when it is wound onto one end of the drum and is wound onto the drum. The reversing point of the wire guide device is obtained according to the outer diameter of the drum on which the yarn is wound, that is, during the winding process, the outer diameter of the drum on which the yarn is wound is continuously increasing, and then the reversing point of the wire guide device can be changed according to the outer diameter of the drum on which the yarn is wound. According to the reversing point, the reversal of the wire guide device is controlled, thereby realizing the reversal of the wire guide device at the reversing point, thereby changing the reversing position of the yarn during the winding process. If the reversing point of the wire guide device is changed at the beginning of the rotation of the drum, due to the large winding angle of the small diameter section of the precision winding, the density of the inner layer of the yarn drum is smaller than that of the outer layer, and the density of the outer edge of the yarn drum is even smaller and cannot support the pressure of the outer layer of yarn, which is similar to an unstable foundation and can easily cause the problem of mesh wire jump. In the present application, when the diameter increases to a certain extent, the reversing position of the wire guide device is changed, thereby changing the reversing position of the yarn, reducing the amount of yarn accumulated on the outer edge of the yarn drum, and changing the pressure of the outer layer of the inner layer of the yarn drum due to the smaller winding angle to the pressure of a certain area on both sides of the yarn drum, which can effectively reduce the deformation of the yarn drum and ensure that the yarn drum can be smoothly unwound in the subsequent doubling process. Moreover, compared with the method of changing the reversing position at the beginning of winding, the density of winding in the early stage of winding can also be guaranteed, which can effectively solve the problems of yarn drum deformation and mesh wire jump.
