Description
Technical Field
[0001] This application relates to the field of textile engineering technology, and in particular to a yarn winding method, apparatus and electronic equipment. Background Technology
[0002] In the textile industry, a spinning frame is a type of textile machinery that twists and drafts roving yarn into fine yarn, which is then wound into a yarn tassel. Its operation can be divided into two parts: the outward twisting process and the return winding process. The outward process refers to the movement of the spinning frame from its starting position to its limit position at a constant speed. During this process, the yarn is twisted, transforming the roving yarn into a fine yarn. The return process refers to the return of the spinning frame from its limit position to its starting position. During this return process, the twisted fine yarn is wound onto an empty yarn bobbin to form a yarn tassel.
[0003] Currently, during the process of winding yarn into tassels, the rise of the guide bow is controlled according to the step-up curve so that the guide bow winds the yarn onto the empty yarn tube to form tassels.
[0004] However, after the yarn thickness is changed, the grade curve needs to be adjusted. The adjusted grade curve needs to be determined through multiple winding operations to determine whether it meets the requirements, and the grade curve that does not meet the requirements needs to be fine-tuned. Since the winding operation takes a long time, the adjustment of the grade curve takes a long time, resulting in low efficiency in winding the yarn on the empty yarn tube. Summary of the Invention
[0005] In view of this, the yarn winding method, apparatus and electronic equipment provided in this application can improve the efficiency of winding yarn on an empty yarn tube.
[0006] According to a first aspect of the present application, a yarn winding method is provided, comprising: determining a first radius based on the size information of an empty yarn tube and the relative position of the empty yarn tube and a guide bow, wherein the first radius is the radius of the empty yarn tube formed at the lower edge of a yarn tassel on the empty yarn tube; determining a second radius of the lower cone of the yarn tassel at the current winding position based on the distance between the current winding position and the lower edge of the yarn tassel in the axial direction of the empty yarn tube during the winding process of the lower cone of the yarn tassel; determining a step-up amount of the guide bow based on the first radius and the second radius, wherein the step-up amount is used to indicate the displacement of the guide bow relative to the empty yarn tube in the axial direction of the empty yarn tube after the current rotation cycle of the empty yarn tube ends; and controlling the movement of the guide bow according to the step-up amount to control the winding position of the yarn guided by the guide bow.
[0007] According to a second aspect of the present application, a yarn winding device is provided, comprising: a first determining unit, configured to determine a first radius based on the size information of an empty yarn tube and the relative position of the empty yarn tube and a guide bow, wherein the first radius is the radius of the empty yarn tube formed at the lower edge of a yarn tassel on the empty yarn tube; a second determining unit, configured to determine a second radius of the lower cone of the yarn tassel at the current winding position based on the distance between the current winding position and the lower edge of the yarn tassel in the axial direction of the empty yarn tube during the winding of the lower cone of the yarn tassel; a third determining unit, configured to determine a step-up amount of the guide bow based on the first radius and the second radius, wherein the step-up amount is used to indicate the displacement of the guide bow relative to the empty yarn tube in the axial direction of the empty yarn tube after the current rotation cycle of the empty yarn tube ends; and a control unit, configured to control the movement of the guide bow according to the step-up amount to control the winding position of the yarn guided by the guide bow.
[0008] According to a third aspect of the present application, an electronic device is provided, comprising: a processor, a communication interface, a memory, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other via the communication bus; the memory is used to store at least one executable instruction, wherein the executable instruction causes the processor to perform an operation corresponding to the yarn winding method provided in the first aspect.
[0009] According to a fourth aspect of the embodiments of this application, a computer-readable storage medium is provided, wherein computer instructions are stored on the computer-readable storage medium, and when executed by a processor, the computer instructions cause the processor to perform the operation corresponding to the yarn winding method provided in the first aspect.
[0010] According to a fifth aspect of the present application, a computer program product is provided, which is tangibly stored on a computer-readable medium and includes computer-executable instructions that, when executed, cause at least one processor to perform a yarn winding method as provided in the first aspect or any possible implementation thereof.
[0011] The above technical solution determines the first radius based on the size information of the empty yarn tube and the relative position of the guide bow and the empty yarn tube. The second radius is determined based on the winding position during the winding of the yarn tassel into the lower cone. Based on the determined first and second radii, the step-up amount of the guide bow can be determined. Since the first and second radii are determined in real time during the yarn winding process, the step-up amount is not determined based on a fixed curve. The step-up amount can change with the change of yarn or the empty yarn tube. Therefore, it is not necessary to redetermine the step-up curve after adjusting the yarn and / or adjusting the size of the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.

[0038] As mentioned earlier, in the textile industry, a spinning frame is a type of textile machinery that twists and drafts roving yarn into fine yarn, which is then wound into a yarn tassel. Its operation can be divided into two processes: the outward twisting process and the return winding process. The outward process refers to the movement of the spinning frame from its starting position to its limit position at a constant speed. During this process, the yarn is twisted, transforming the roving yarn into a fine yarn. The return process refers to the return of the spinning frame from its limit position to its starting position. During this process, the twisted fine yarn is wound onto an empty yarn tube to form a yarn tassel.
[0039] Currently, two main methods are used to control the step height of the yarn guide bow;
[0040] Method 1: Control the step-up of the yarn guide bow through a mechanical cam method. Specifically, the step-up of the yarn guide bow is controlled by a mechanical cam driven by a motor, thereby achieving the formation of yarn tassels.
[0041] However, changing the forming size of the lower cone of the yarn tassel requires changing different mechanical cams, which is a complicated process. This results in low efficiency in winding the fine yarn onto the empty yarn tube, and the mechanical meshing accuracy will decrease due to wear, which reduces the forming accuracy of the yarn tassel and makes it impossible to achieve the ideal forming effect.
[0042] Method 2: During the process of winding the yarn into a tassel, the rise of the guide bow is controlled according to the step-up curve. As the number of windings increases, the step-up curve gradually decreases, thereby controlling the guide bow to wind the yarn onto the empty yarn tube to form a tassel.
[0043] However, after the yarn thickness is changed, the grade curve needs to be adjusted. The adjusted grade curve needs to be determined through multiple winding operations to determine whether it meets the requirements, and the grade curve that does not meet the requirements needs to be fine-tuned. Since the winding operation takes a long time, the adjustment of the grade curve takes a long time, resulting in low efficiency in winding the fine yarn onto the empty yarn tube.
[0044] In summary, the yarn winding methods in related technologies have low efficiency in winding fine yarn onto empty yarn tubes.
[0045] In this embodiment, a first radius is determined based on the size information of the empty yarn tube and the relative position of the guide bow and the empty yarn tube. A second radius is determined based on the winding position during the winding of the yarn tassel into the lower cone. Based on the determined first and second radii, the step-up amount of the guide bow can be determined. Since the first and second radii are determined in real time during the yarn winding process, the step-up amount is not determined based on a fixed curve. The step-up amount can change with the change of the yarn or the empty yarn tube, thus eliminating the need to re-determine the step-up curve after adjusting the yarn and / or the size of the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0046] The yarn winding method, apparatus, and electronic equipment provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0047] Figure 1 This is a flowchart of a yarn winding method 100 provided in an embodiment of this application. For example... Figure 1 As shown, the yarn winding method 100 includes the following steps:
[0048] Step 101: Determine the first radius based on the size information of the empty yarn tube and the relative position of the empty yarn tube and the guide bow.
[0049] During yarn winding, the empty yarn tube rotates under the control of the machine, and the position of the guide bow relative to the empty yarn tube changes vertically, thereby winding the yarn onto the empty yarn tube. The first radius is the radius of the empty yarn tube at the lower edge of the yarn tassel formed on the empty yarn tube, that is, the radius of the empty yarn tube at the position of the bottom surface of the yarn tassel. During yarn winding, the base layer is first wound on the empty yarn tube from top to bottom. The base layer can prevent the yarn from falling off the empty yarn tube during the winding process. Then, the guide bow winds the yarn tassel from bottom to top, and the starting point of the winding is the lower edge of the yarn tassel formed on the empty yarn tube.
[0050] Step 102: During the winding of the lower cone of the yarn tassel, determine the second radius of the lower cone of the yarn tassel at the current winding position based on the distance between the current winding position and the lower edge of the yarn tassel along the axial direction of the empty yarn tube.
[0051] During the process of winding the yarn tassel from bottom to top, the lower cone of the yarn tassel is wound first. Based on the distance between the current winding position and the lower edge of the yarn tassel along the axial direction of the empty yarn tube, the current winding position of the lower cone can be determined. Thus, the second radius of the lower cone of the yarn tassel at the current winding position can be determined. It should be understood that the second radius is a real-time radius, which changes as the winding position changes.
[0052] Step 103: Determine the step height of the guide bow based on the first radius and the second radius.
[0053] The rise of the guide bow is calculated based on the first radius and the second radius. The rise indicates the displacement of the guide bow relative to the empty yarn tube in the direction of the empty yarn tube axis after the current rotation cycle of the empty yarn tube is completed. That is, the rise of the guide bow after the yarn is wound around the empty yarn tube once. The starting position of the rise for each winding of the yarn is usually achieved by adding a rise to the position of the previous rise.
[0054] Step 104: Control the movement of the guide bow according to the step height to control the winding position of the yarn guided by the guide bow.
[0055] Based on the determined rise of the guide bow, the movement of the guide bow along the axis of the empty yarn tube can be controlled, thereby controlling the winding position of the yarn guided by the guide bow.
[0056] In this embodiment, a first radius is determined based on the size information of the empty yarn tube and the relative position of the guide bow and the empty yarn tube. A second radius is determined based on the winding position during the winding of the yarn tassel into the lower cone. Based on the determined first and second radii, the step-up amount of the guide bow can be determined. Since the first and second radii are determined in real time during the yarn winding process, the step-up amount is not determined based on a fixed curve. The step-up amount can change with the change of the yarn or the empty yarn tube, thus eliminating the need to re-determine the step-up curve after adjusting the yarn and / or the size of the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0057] In one possible implementation, when determining the first radius based on the size information of the empty yarn tube and the relative position of the empty yarn tube and the guide bow, the top radius of the upper cone of the empty yarn tube and the top radius of the lower cone of the empty yarn tube can be determined. The top radius of the upper cone of the empty yarn tube is smaller than the bottom radius of the upper cone of the empty yarn tube, and the top radius of the lower cone of the empty yarn tube is smaller than the bottom radius of the lower cone of the empty yarn tube. Then, the position of the guide bow corresponding to the top of the lower cone of the empty yarn tube and the position of the guide bow corresponding to the lower edge of the yarn tassel are determined. The first radius is determined based on the top radius of the upper cone of the empty yarn tube, the top radius of the lower cone of the empty yarn tube, the position of the guide bow corresponding to the top of the lower cone of the empty yarn tube, and the position of the guide bow corresponding to the lower edge of the yarn tassel.
[0058] When the empty yarn tube is a double-cone empty yarn tube, the top radius of the upper cone and the top radius of the lower cone included in the empty yarn tube can be determined based on the size information of the empty yarn tube. The bottom of the upper cone and the top of the lower cone are connected to form the entire empty yarn tube. In this embodiment, the empty yarn tubes are placed with the upper cone on top and the lower cone on the bottom. At this time, the top radius of the upper cone is smaller than the bottom radius of the upper cone, and the top radius of the lower cone is smaller than the bottom radius of the lower cone.
[0059] Based on the relative positions of the empty yarn tube and the guide bow, the position of the guide bow corresponding to the top of the lower cone of the empty yarn tube and the position of the guide bow corresponding to the lower edge of the yarn tassel can be determined. It should be understood that the relative positions of the empty yarn tube and the guide bow can indicate the winding position of the yarn when the guide bow is in different positions. When the guide bow is located at the position corresponding to the top of the lower cone of the empty yarn tube, if the yarn is to be wound, the winding will start from the top of the lower cone of the empty yarn tube.
[0060] In this embodiment, the top radius of the upper cone and the top radius of the lower cone of the empty yarn tube are determined based on the size information of the empty yarn tube. Based on the relative position of the empty yarn tube and the guide bow, the position of the guide bow corresponding to the top of the lower cone of the empty yarn tube and the position of the guide bow corresponding to the lower edge of the yarn tassel are determined. Thus, the first radius can be calculated. When the size of the empty yarn tube changes and / or the yarn winding position changes, the first radius changes accordingly, realizing the real-time calculation of the first radius.
[0061] In one possible implementation, when determining the first radius based on the top radius of the upper cone of the empty yarn tube, the top radius of the lower cone of the empty yarn tube, the position of the guide bow corresponding to the top of the lower cone of the empty yarn tube, and the position of the guide bow corresponding to the lower edge of the yarn tassel, if the height of the guide bow corresponding to the top of the lower cone of the empty yarn tube is less than the height of the guide bow corresponding to the lower edge of the yarn tassel (i.e., the lower edge of the yarn tassel is located on the upper cone of the empty yarn tube), the first radius is calculated using the following first formula:
[0062]
[0063] Figure 2 This is a schematic diagram of the structure of an empty yarn tube 200 provided in an embodiment of this application, as shown below. Figure 2 As shown, R3 is used to characterize the first radius, R1 is used to characterize the top radius of the lower cone of the empty yarn tube, R2 is used to characterize the top radius of the upper cone of the empty yarn tube, Pos2 is used to characterize the height of the guide bow corresponding to the lower edge of the yarn tassel, Pos1 is used to characterize the height of the guide bow corresponding to the top of the lower cone of the empty yarn tube, and H1 is used to characterize the height of the upper cone of the empty yarn tube.
[0064] When the height of the guide arch corresponding to the top of the lower cone of the empty yarn tube is greater than the height of the guide arch corresponding to the lower edge of the yarn tassel, that is, when the lower edge of the yarn tassel is located on the lower cone of the empty yarn tube, the first radius is calculated using the following second formula:
[0065]
[0066] like Figure 2 As shown, R4 is used to characterize the bottom radius of the cone under the empty yarn tube, Pos3 is used to characterize the height of the guide bow position corresponding to the bottom of the cone under the empty yarn tube, and H2 is used to characterize the height of the cone under the empty yarn tube.
[0067] In this embodiment, when the lower edge of the yarn tassel is located on the upper cone of the empty yarn tube, the first radius is calculated using the first formula; when the lower edge of the yarn tassel is located on the lower cone of the empty yarn tube, the first radius is calculated using the second formula. This allows for the calculation of the first radius at different winding positions, thus making it applicable to different situations when the yarn is wound at different positions on the empty yarn tube, thereby improving the applicability of the yarn winding method.
[0068] In one possible implementation, when determining the second radius of the lower cone of the yarn at the current winding position based on the distance between the current winding position and the lower edge of the yarn tassel along the axial direction of the empty yarn tube, the second radius can be calculated using the following third formula:
[0069]
[0070] like Figure 2 As shown, R6 is used to characterize the second radius, R5 is used to characterize the set radius of the upper part of the lower cone of the yarn tassel when the winding of the lower cone of the yarn tassel is completed, H3 is used to characterize the distance between the current winding position and the lower edge of the yarn tassel in the axial direction of the empty yarn tube, and H4 is used to characterize the set height between the upper part and the bottom of the lower cone of the yarn tassel when the winding of the lower cone of the yarn tassel is completed.
[0071] In this embodiment of the application, the second radius can be calculated according to the third formula. Since the second radius is calculated based on the distance between the current winding position and the lower edge of the yarn tassel in the axial direction of the empty yarn tube, different winding positions correspond to different second radii. Thus, the step-up amount calculated based on the second radius is different at different winding positions, so that the yarn can be wound into a yarn tassel.
[0072] Figure 3 This is a flowchart of a step-up calculation method 300 provided in an embodiment of this application, as shown below. Figure 3 As shown, when determining the step height of the guide bow based on the first radius and the second radius, the following steps can be taken:
[0073] Step 301: Calculate the number of windings based on the first radius.
[0074] The number of windings is calculated based on the first radius. The number of windings corresponds to the number of turns of the yarn on the empty yarn tube. Each winding results in one turn of the yarn on the empty yarn tube. It should be understood that since the empty yarn tube rotates in a fixed position, the number of windings also corresponds to the number of turns of the empty yarn tube.
[0075] Step 302: Calculate the average grade rise based on the number of windings and the preset height of the cone under the yarn tassel.
[0076] The average grade rise is calculated based on the number of windings and the preset height of the lower cone of the yarn tassel. Specifically, the average grade rise can be calculated using the following formula: Average grade rise = Preset height of the lower cone of the yarn tassel ÷ Number of windings. The preset height of the lower cone of the yarn tassel is the total grade rise of the guide bow during the winding process. Dividing the preset height of the lower cone of the yarn tassel by the number of windings allows us to calculate the average grade rise of the guide bow during each winding.
[0077] Step 303: Calculate the initial level rise at the start of winding the lower cone of the yarn tassel, and the final level rise when winding the lower cone of the yarn tassel is completed, based on the average level rise and the first radius.
[0078] The initial rise is the first rise of the guide bow when the yarn starts winding from the lower cone of the tassel, and the final rise is the last rise of the guide bow when the lower cone of the tassel finishes winding.
[0079] Step 304: Determine the level rise based on the average level rise, initial level rise, final level rise, first radius, and second radius.
[0080] In this embodiment, the number of windings is calculated based on the first radius, and the initial and final level rises are determined based on the number of windings, thereby calculating the level rise. Therefore, the level rise can be determined based on the first and second radii, which are determined in real time during the yarn winding process. Thus, the level rise is not determined based on a fixed curve, but can change with the yarn and / or the size of the empty yarn tube. This eliminates the need to re-determine the level rise curve after changing the yarn and / or the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0081] In one possible implementation, when calculating the number of windings based on the first radius, the number of windings can be calculated using the following fourth formula:
[0082]
[0083] n represents the number of windings, T represents the preset yarn diameter fill factor, R0 represents the yarn radius; Trunc() represents the rounding function. P is used to characterize the preset yarn count.
[0084] In this embodiment, the number of windings is calculated using a fourth formula. Since the number of windings is calculated based on the yarn radius and the first radius, the number of windings changes when the yarn radius and / or the first radius changes, resulting in a change in the level rise. Therefore, the level rise is not determined based on a fixed curve. The level rise can change with the yarn or the size of the empty yarn tube, thus eliminating the need to redetermine the level rise curve after changing the yarn and / or the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0085] In one possible implementation, when calculating the initial grade rise at the start of winding the lower cone of the yarn tassel based on the average grade rise and the first radius, and the final grade rise when winding the lower cone of the yarn tassel is completed, the initial grade rise can be calculated using the following fifth formula:
[0086]
[0087] L1 is used to characterize the initial stage lift, and L0 is used to characterize the average stage lift;
[0088] The final stage lift can be calculated using the following sixth formula:
[0089]
[0090] L2 is used to characterize the initial stage rise.
[0091] In this embodiment, the initial level rise is calculated using the fifth formula, and the final level rise is calculated using the sixth formula. Since the initial and final level rise are calculated based on the average level rise and the first radius in the fifth and sixth formulas, and the number of windings is calculated based on the yarn radius and the first radius, when the yarn radius and / or the first radius changes, the number of windings changes, resulting in a change in the average level rise, which in turn causes a change in the initial and final level rise. Therefore, the level rise is not determined based on a fixed curve, but can change with the yarn and / or the size of the empty yarn tube. This eliminates the need to determine the level rise curve after changing the yarn and / or the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0092] In one possible implementation, when determining the level rise based on the average level rise, initial level rise, final level rise, first radius, and second radius, the level rise at the lower cone of the wound yarn tassel can be calculated using the following seventh formula:
[0093]
[0094] like Figure 2 As shown, L3 is used to characterize the amount of lift when the yarn is wound into the lower cone.
[0095] In this embodiment, the grade rise is calculated using the seventh formula. Since the grade rise is calculated using the initial grade rise and the final grade rise, when the yarn radius and / or the first radius changes, the number of windings changes, resulting in a change in the average grade rise, which in turn causes changes in the initial grade rise and the final grade rise, thus causing a change in the grade rise. Therefore, the grade rise is not determined based on a fixed curve. The grade rise can change with the yarn and / or the size of the empty yarn tube, thus eliminating the need to determine the grade rise curve after changing the yarn and / or the empty yarn tube, thereby improving the efficiency of winding the yarn onto the empty yarn tube.
[0096] In one possible implementation, the lift of the winding yarn core can be calculated using the following eighth formula:
[0097] L4 = L0 * K (Eighth Formula)
[0098] Wherein, L4 is used to characterize the lift amount when the yarn is wound to form the column in the tassel, and K is used to characterize the preset lift coefficient.
[0099] It should be understood that since the thickness of the central column is uniform, the lift is a fixed constant. K is a preset lift coefficient, which is generally in the range of [1, 1.5]. The finer the yarn, the closer the lift coefficient is to 1, which allows the central column to be wound into shape.
[0100] In this embodiment of the application, the step height when the yarn is wound to form the column in the tassel can be calculated according to the eighth formula. Therefore, the yarn can continue to be wound after the lower cone of the tassel is completed, so that the tassel can be wound into a preset shape. Therefore, this yarn winding method can be applied to the winding of columns and has high applicability.
[0101] Figure 4 This is a schematic diagram of a yarn winding device 400 provided in an embodiment of this application. Figure 4 As shown, the yarn winding device 400 includes:
[0102] The first determining unit 401 is used to determine the first radius based on the size information of the empty yarn tube and the relative position of the empty yarn tube and the guide bow, wherein the first radius is the radius of the empty yarn tube at the lower edge of the yarn tassel formed on the empty yarn tube;
[0103] The second determining unit 402 is used to determine the second radius of the lower cone of the yarn at the current winding position based on the distance between the current winding position and the lower edge of the yarn in the axial direction of the empty yarn tube during the winding process of the lower cone of the yarn.
[0104] The third determining unit 403 is used to determine the step lift of the guide bow according to the first radius and the second radius, wherein the step lift is used to indicate the displacement of the guide bow relative to the empty yarn tube in the direction of the empty yarn tube axis after the current rotation cycle of the empty yarn tube ends.
[0105] Control unit 404 is used to control the movement of the guide bow according to the step lift, so as to control the winding position of the yarn guided by the guide bow.
