Description

Technical Field

[0001] The invention belongs to the technical field of intelligent control, and in particular relates to a control system for a tubular textile yarn packaging and detection integrated machine. Background Art

[0002] Tubular textile yarn is widely used in various industrial and consumer products. Its advantage of being provided in the form of a reel allows textile machines to operate continuously without frequent yarn changes, which greatly improves production efficiency while reducing manual intervention, labor costs and operational complexity, making it play an important role in textile and industrial production.

[0003] At present, in order to save time in the production process of tubular textile yarn, synchronous integrated control of winding and packaging is usually adopted, which can reduce the frequency of stopping for shaft changing, thereby improving the continuity and efficiency of the production line. At the same time, it can simplify the operating process, reduce the workload of operators, and improve the accuracy and safety of operations.

[0004] Winding control is crucial in the integrated production control of tubular textile yarns, mainly because it directly affects the quality of the yarn, production efficiency and stability of the final product. In the prior art, although the Chinese invention patent with publication number CN117945226A provides an intelligent yarn winding system and method based on intelligent control, the solution uses a sensor group to monitor and collect yarn tension and winding speed in real time, and uses an artificial intelligence-based data processing and analysis algorithm to perform time series data correlation processing and analysis of the yarn tension and the winding speed, so as to adaptively adjust the winding speed value according to the time series coordinated correlation changes between the yarn tension and the winding speed, thereby realizing automatic adjustment of the winding speed.

[0005] Although the above scheme can realize automatic winding control of yarn without human intervention, it only relies on yarn tension to control the winding speed during winding control, ignoring the ambient temperature. Changes in ambient temperature will affect the physical properties of the yarn, causing changes in the tension of the yarn during the winding process, thereby affecting the control accuracy and control fluctuation of the winding speed. The winding speed that varies from time to time will lead to a decrease in production efficiency and an increase in the production cycle.

[0006] In addition, the winding control targeted by the above scheme belongs to the forward control based on the yarn tension, and lacks attention to the feedback control based on the yarn winding results, which means that the detection and control errors in the winding process cannot be detected and corrected in time, which will affect the forward control effect on the one hand, and on the other hand, the delay in processing the detection and control errors will lead to more waste and defective products, which will invisibly increase the production cost. Summary of the invention

[0007] In view of this, the present invention aims to propose a control system for a tubular textile yarn packaging and detection integrated machine, which optimizes the yarn winding control by adding feedback control based on ambient temperature and yarn winding results during the yarn winding process.

[0008] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a control system for a tubular textile yarn packaging and detection integrated machine, including a winding platform composed of a yarn supply device, a winding machine, a tubular reel, a winding detection terminal, an adjusting roller, and a winding control terminal, and a packaging detection platform composed of a packaging detection terminal and an alarm device. The specific module structure is as follows: a yarn supply module, which is used to fix the yarn material on the yarn supply device for yarn supply.

[0009] The yarn winding detection module is used to detect the yarn tension, winding speed and ambient temperature in real time during the yarn winding process using a winding detection terminal arranged on the winding platform.

[0010] The yarn winding associated control module is used to perform associated control using a winding control terminal based on yarn tension, winding speed and ambient temperature detection results during the yarn winding process.

[0011] The yarn winding area identification module is used to divide the winding area according to the length of the tubular reel and mark the boundary line, so as to identify the winding position of the yarn on the tubular reel in real time during the winding process, and use the winding area boundary line to obtain the winding area to which the winding position belongs.

[0012] The winding density analysis module is used to set the winding stage and focus the cylindrical reel on the winding area corresponding to the winding stage to perform winding density analysis.

[0013] The associated winding stage screening module is used to form a time series set of the winding speed and tension detected in the winding stage, and to construct a winding speed curve and a yarn tension curve based on this, and then to compare the winding speed curves and yarn tension curves constructed in adjacent winding stages for similarity, so as to screen out the associated winding stages.

[0014] The winding feedback control module is used to identify the deviation of the winding density in the associated winding stage and perform winding feedback control if there is a deviation.

[0015] The winding quality detection module is used to transport the finished yarn winding products to the packaging and testing platform, and the packaging and testing terminal performs winding quality detection.

[0016] The winding qualification evaluation module is used to perform qualification evaluation based on the winding quality detection results using an alarm device.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention detects yarn tension, winding speed and ambient temperature in real time during the production of tubular textile yarn, thereby identifying the winding control object and implementing the winding control based on the detection results. It is not limited to winding speed control. On the one hand, it realizes the refined and reasonable control of yarn winding, which can maximize the actual control needs of yarn winding. On the other hand, since it is not limited to winding speed control, it will greatly avoid the control fluctuation of winding speed, which is conducive to maintaining the stability of production efficiency.

[0018] 2. The present invention sets winding stages in yarn winding, thereby utilizing the tension and winding speed control of adjacent winding stages to identify related winding stages, and then performs feedback control based on the winding effect deviation of the related winding stage to form a closed-loop feedback of the yarn winding, thereby achieving both positive control based on yarn tension and feedback control based on yarn winding results in yarn winding. It can not only provide a supplement to the positive control effect and improve the control effect, but also can promptly identify detection control errors to avoid processing delays, thereby helping to reduce production costs.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention proposes a control system for a tubular textile yarn packaging and detection integrated machine, comprising a winding platform consisting of a yarn supply device, a winding machine, a tubular reel, a winding detection terminal, an adjusting roller, and a winding control terminal, and a packaging detection platform consisting of a packaging detection terminal and an alarm device. The specific operations include a yarn supply module, a yarn winding detection module, a yarn winding associated control module, a yarn winding area identification module, a winding density analysis module, an associated winding stage screening module, a winding feedback control module, a winding quality detection module, and a winding qualified judgment module.

[0025] See also Figure 1 As shown, the connection relationship between the modules included in the system is that the yarn supply module is connected to the yarn winding detection module, the yarn winding detection module is connected to the yarn winding associated control module, the yarn winding area identification module is connected to the winding density analysis module, the yarn winding detection module is connected to the associated winding stage screening module, the associated winding stage screening module and the winding density analysis module are both connected to the winding feedback control module, and the winding quality detection module is connected to the winding qualification evaluation module.

[0026] See also Figure 2 As shown, in the winding platform, the yarn supply device is used to fix the yarn material to ensure that the yarn is continuously supplied to the winding machine. The winding machine is a device used to wind the yarn provided by the yarn supply device onto a cylindrical reel. The winding detection terminal is used to detect the yarn tension of the yarn supply device, the winding speed of the winding machine and the ambient temperature during the yarn winding process. Specifically, the winding detection terminal can be composed of a tension sensor, a speed sensor and a temperature sensor, wherein the tension sensor is generally installed on the yarn supply device, the speed sensor is usually installed on the motor shaft or the winding wheel of the winding machine, and the temperature sensor is generally installed in the environment around the winding machine to ensure that accurate ambient temperature data is obtained. The adjusting roller is used to adjust the tension of the yarn. For example, the adjusting roller can be a tension roller. By setting the roller in the yarn supply path, the position or pressure of the roller can be adjusted to change the tension of the yarn. Specifically, by increasing or decreasing the pressure on the yarn, the tension of the yarn can be accurately controlled. In another example, the adjusting roller can be a guide roller. The angle and position of the guide roller are used to indirectly adjust the tension of the yarn. Specifically, by changing the position and angle of the guide roller, the supply path and tension distribution of the yarn can be affected. In another example, the adjusting roller can be a friction roller. The friction force of the friction roller can be adjusted to control the tension of the yarn. The winding control terminal is used to analyze the winding data detected by the winding detection terminal to achieve the purpose of controlling the adjusting roller and the winding machine.

[0027] The yarn supply module is used to fix the yarn material on the yarn supply device for yarn supply.

[0028] The yarn winding detection module is used to detect the yarn tension, winding speed and ambient temperature in real time during the yarn winding process using a winding detection terminal arranged on the winding platform.

[0029] The yarn winding associated control module is used to perform associated control using a winding control terminal based on yarn tension, winding speed and ambient temperature detection results during the yarn winding process.

[0030] In the innovative implementation of the above scheme, an associated control evaluation is required before the associated control operation. The specific operations are as follows: compare the real-time detected yarn tension with the reasonable tension range set by the system, and compare the real-time detected ambient temperature with the safe temperature range set by the system. If the yarn tension at a certain moment is not within the reasonable tension range set by the system or the ambient temperature is not within the safe temperature range set by the system, it is judged that associated control is required, and the winding control guide is determined. If the winding control guide is yarn tension, the tension detected at that moment is recorded as abnormal tension. If the winding control guide is ambient temperature, the ambient temperature detected at that moment is recorded as abnormal temperature. Otherwise, it is judged that associated control is not required.

[0031] It should be added that the above-mentioned reasonable tension range is largely determined by the type of yarn material and the diameter specifications of the yarn. Different materials (such as cotton, polyester, nylon, etc.) have different physical properties and tolerances. The same yarn material has different diameters and different tolerances. When determining the reasonable tension range, the tension should be kept within the maximum tolerance range of the yarn to avoid exceeding the tensile strength of the yarn. Excessive tension may cause yarn breakage, while too low tension may cause uneven winding or loosening. The specific information can be extracted from the technical manual based on the selected yarn material and diameter.

[0032] Another thing that needs to be added is that the safe temperature range is also largely determined by the type of yarn material. Different yarn materials have different temperature tolerance. When determining the safe temperature range, the safe temperature range should be determined based on the melting point, glass transition temperature or other thermal properties of the yarn.

[0033] In the preferred implementation of the above scheme, the winding control guide is determined specifically as follows: when the yarn tension at a certain moment is not within the reasonable tension range set by the system but the ambient temperature is within the safe temperature range set by the system, the winding control guide is determined to be the yarn tension; when the yarn tension at a certain moment is within the reasonable tension range set by the system but the ambient temperature is not within the safe temperature range set by the system, the winding control guide is determined to be the ambient temperature; when the yarn tension at a certain moment is not within the reasonable tension range set by the system and the ambient temperature is not within the safe temperature range set by the system, the winding control guide is determined to be the yarn tension and the ambient temperature.

[0034] Furthermore, the associated control specifically refers to the following process: S1 when the winding control guide is yarn tension, the abnormal tension is compared with the reasonable tension range set by the system. If the abnormal tension is less than the minimum value of the reasonable tension range set by the system, the winding control object is determined to be the winding speed, and the winding speed of the winding machine is increased by using the winding control terminal. If the abnormal tension is greater than the maximum value of the reasonable tension range set by the system, the winding control object is determined to be the yarn tension, and the yarn tension is reduced by using the adjusting roller to make it within the reasonable tension range set by the system.

[0035] It should be understood that when the winding control guide is yarn tension, it means that the current ambient temperature is suitable. At this time, if the abnormal tension is less than the minimum value of the reasonable tension range set by the system, it means that the tension is too loose. By increasing the winding speed of the winder to increase the yarn tension, it helps to restore it to the appropriate range. At the same time, increasing the winding speed can also improve the winding efficiency. If the abnormal tension is greater than the maximum value of the reasonable tension range set by the system, it means that the tension is too tight. At this time, using the adjusting roller to reduce the tension instead of reducing the winding speed can keep the speed of the production line unchanged and ensure that production efficiency will not be affected. In addition, the adjusting roller provides a more detailed tension adjustment method, which helps to reduce tension fluctuations and maintain the stability of the winding process.

[0036] S2 When the winding control guide is the ambient temperature, the winding control object is determined to be the winding speed. The winding speed of the winder is reduced by using the winding control terminal. At the same time, the yarn tension is detected. If the yarn tension is less than the minimum value of the reasonable tension range set by the system while the winding speed is reduced, the adjusting roller is used to increase the yarn tension so that it is within the reasonable tension range set by the system.

[0037] It should be understood that when the winding control guide is the ambient temperature, it means that the current yarn tension is normal and meets the requirements. When the ambient temperature is too high, the yarn may become softer, making it difficult to control the tension. If the yarn tension is controlled at this time, it will not only destroy the original normal yarn tension, but also may cause the yarn to deform and break. Therefore, by reducing the winding speed, the yarn processing speed can be slowed down, reducing the risk of tension instability and deformation caused by temperature increase. This helps prevent yarn deformation, breakage or other quality problems. When the ambient temperature is too low, the yarn may become more brittle and easy to break. At this time, yarn tension control will also cause yarn breakage. By reducing the winding speed, the risk of breakage caused by the hardening of the yarn can be reduced.

[0038] S3 When the winding control guide is yarn tension and ambient temperature, the abnormal tension is compared with the reasonable tension range set by the system. If the abnormal tension is greater than the maximum value of the reasonable tension range set by the system, the winding control object is determined to be the winding speed, and the winding speed of the winder is reduced by using the winding control terminal. If the abnormal tension is less than the minimum value of the reasonable tension range set by the system, the winding control object is determined to be the winding speed and yarn tension, and the winding speed of the winder is reduced by using the winding control terminal. At the same time, the adjusting roller is used to increase the yarn tension so that it is within the reasonable tension range set by the system.

[0039] It should be understood that when the winding control is guided by yarn tension and ambient temperature, it means that both the yarn tension and the ambient temperature do not meet the requirements. In this case, for the yarn tension, in the first case, if the abnormal tension is greater than the maximum value of the reasonable tension range set by the system, it means that the tension is too tight and the winding speed needs to be reduced or the yarn tension needs to be adjusted. For the ambient temperature, refer to S2 and the winding speed needs to be reduced. When both are considered at the same time, the winding speed needs to be reduced. In the second case, for the yarn tension, if the abnormal tension is less than the minimum value of the reasonable tension range set by the system, it means that the tension is too loose and the winding speed needs to be increased or the yarn tension needs to be adjusted. For the ambient temperature, refer to S2 and the winding speed needs to be reduced. When both are considered at the same time, the winding control is achieved by reducing the winding speed and adjusting the yarn tension at the same time.

[0040] It should be emphasized that the control of winding speed and yarn tension mentioned in the present invention mainly focuses on the control object and control direction, wherein the control direction is increase or decrease, and the specific control value is not the focus of the winding control of the present invention.

[0041] The yarn winding area identification module is used to divide the winding area according to the length of the tubular reel and mark the boundary line, thereby identifying the winding position of the yarn on the tubular reel in real time during the winding process, and using the winding area boundary line to obtain the winding area to which the winding position belongs.

[0042] In the specific implementation of the above scheme, when dividing the winding area of ​​the cylindrical reel, as many divisions as possible are made while ensuring uniform division, so as to provide refined winding areas, and ensure that different winding stages are in different winding areas when the winding areas of different winding stages are determined according to the winding position later. This helps to compare the winding density of different winding stages. At the same time, after the winding is completed, the winding status or quality problems of different areas can be easily identified and tracked according to the subdivided areas, which is convenient for subsequent quality control and inspection.

[0043] In a further specific implementation of the above scheme, the winding position of the yarn on the tubular reel can be identified by taking an image of the reel through a visual sensor, and analyzing the winding position of the yarn through image processing software. At the same time, the use of the visual sensor can not only determine the winding position but also perform winding density analysis.

[0044] The winding density analysis module is used to set the winding stage, wherein the winding stage can predict the winding time based on the historical winding records, and then divide the winding time into winding stages, and focus the cylindrical reel on the winding area corresponding to the winding stage for winding density analysis. The specific analysis is as follows: in the winding area of ​​the winding stage, the visual sensor is used to collect images, and the outline of each circle of the winding area is identified and tracked from the collected image, and the total number of winding circles is obtained by calculating the number of each winding circle.

[0045] The winding density is obtained by dividing the total number of winding turns on the winding area by the length of the winding area.

[0046] The associated winding stage screening module is used to form a time series set of the winding speed and yarn tension detected in the winding stage, and to construct a winding speed curve and a yarn tension curve based on this, and then to perform similarity comparison on the winding speed curves and yarn tension curves constructed in adjacent winding stages to screen out the associated winding stages.

[0047] Preferably, the winding speed curve and the yarn tension curve are constructed as follows: the winding speed and yarn tension time series formed in the winding stage are set and several points are marked in a coordinate system with time as the horizontal axis and the winding speed and yarn tension as the vertical axis to form the winding speed curve and the yarn tension curve.

[0048] Further preferably, the winding speed curve and yarn tension curve constructed in adjacent winding stages are similarly compared as follows: the winding speed curve and yarn tension curve of adjacent winding stages are overlapped and compared to obtain the winding speed overlapping section and the yarn tension overlapping section, and the total length of the winding speed overlapping section and the yarn tension overlapping section is counted, and the total length is divided by the length of the winding speed curve and the yarn tension curve of the previous winding stage in the adjacent winding stage to obtain the winding speed overlap degree and the yarn tension overlap degree corresponding to the adjacent winding stages.

[0049] In the overlapping comparison of the winding speed curve and the yarn tension curve in adjacent winding stages, the winding speed overlapping sections and the yarn tension overlapping sections are marked, and the marked overlapping sections are numbered according to the order in which the overlapping sections appear on the curve.

[0050] The numbered winding speed overlap sections and yarn tension overlap sections in adjacent winding stages are analyzed for continuity, and the winding speed overlap continuity and yarn tension overlap continuity of adjacent winding stages are obtained.

[0051] The winding speed similarity of adjacent winding stages is obtained by multiplying the winding speed coincidence degree and the winding speed coincidence continuity degree of adjacent winding stages and taking the percentage. Similarly, the yarn tension similarity of adjacent winding stages is obtained by multiplying the yarn tension coincidence degree and the yarn tension coincidence continuity degree of adjacent winding stages.

[0052] When comparing the similarities of winding speed and yarn tension in adjacent winding stages, the present invention combines the two dimensions of overlap and overlap continuity for evaluation. The overlap measures the overall similarity of the curves, while the overlap continuity focuses on the overlap coherence of the curves. Combining these two dimensions can more comprehensively evaluate the similarity of winding control in adjacent stages, making the evaluation more accurate.

[0053] Further preferably, the screening process of associated winding stages is as follows: the winding speed similarity and the yarn tension similarity of adjacent winding stages are respectively compared with the similarity threshold preset by the system. Exemplarily, the similarity threshold is 90%. If the winding speed similarity and the yarn tension similarity of certain adjacent winding stages both reach the similarity threshold, then the adjacent winding stage is used as an associated winding stage.

[0054] It should be noted that when performing a similarity comparison of the winding speeds and yarn tensions of adjacent winding stages according to the order of appearance of the winding stages, if no associated winding stages appear, the winding stages can be compared for similarity at intervals, that is, the winding speeds and yarn tensions of the first winding stage and the third winding stage can be compared for similarity, so as to screen out the associated winding stages.

[0055] The winding feedback control module is used to further identify the deviation of the winding density in the associated winding stage, and perform winding feedback control if there is a deviation.

[0056] Applied to the above scheme, the deviation identification operation of the winding density of the associated winding stage is as follows: the winding density of the associated winding stage is subtracted and the absolute value is taken, and the result of the absolute value is divided by the winding density of the previous winding stage in the associated winding stage to obtain the winding density deviation value, which is then compared with the allowable deviation value configured by the system. For example, the allowable deviation value can be 0.3. If the winding density deviation value is greater than the allowable deviation value, it is identified that there is a deviation.

[0057] It should be understood that the feedback control based on the winding density deviation in the associated winding stage takes into account that the winding speed and yarn tension control provided in the associated winding stage are similar, but the winding density has deviations, which suggests that there is an error in the detection terminal or the control terminal. In addition, by comparing the winding speed in the associated winding stage, it helps to ensure that the density deviation detected under similar operating conditions truly reflects the winding error, rather than the error caused by the change of operating conditions.

[0058] Further, the winding feedback control refers to the following process: the offset of the cylindrical reel in the front winding stage and the rear winding stage in the associated winding stage with the winding speed deviation is detected to obtain the offset of the cylindrical reel in the corresponding associated winding stage.

[0059] The control error and detection error of the winding control terminal and the winding detection terminal in the front winding stage and the rear winding stage in the associated winding stage where there is a winding speed deviation are measured to obtain the control error and detection error of the winding control terminal in the corresponding associated winding stage.

[0060] The control error amount and the detection error amount are compared with the permitted control error amount and the permitted detection error amount respectively, thereby determining the feedback control object, and then calibrating and adjusting the feedback control object in the next winding stage.

[0061] The above-mentioned allowable control error amount and allowable detection error amount are based on the specifications and models of the winding control terminal and the winding detection terminal, and are obtained from their instructions for use.

[0062] Furthermore, the feedback control object is determined as follows: when the control error is higher than the permitted control error, the feedback control object is determined to be a winding control terminal; when the detection error is higher than the permitted detection error, the feedback control object is determined to be a winding detection terminal.

[0063] See also Figure 3 As shown, the packaging inspection terminal is composed of a high-resolution camera, a diameter sensor, a thickness gauge, etc., wherein the high-resolution camera is used to identify the appearance defects of the finished yarn winding product, and the diameter sensor and the thickness gauge are used to detect the diameter, thickness and other dimensional indicators of the finished yarn winding product. The alarm device is used to alarm to remind the operator and display the specific quality defects when the finished yarn winding product is judged to be unqualified based on the winding quality inspection results, wherein the alarm device can be a combination of a warning light, a buzzer or other auditory alarm and a display terminal, wherein the warning light, buzzer or other auditory alarm is used for alarm, and the display terminal is used to display the specific quality defects.

[0064] The winding quality detection module is used to transport the finished yarn winding products to the packaging detection platform after winding, and the packaging detection terminal performs winding quality detection. The specific detection is: identifying appearance defects of the finished yarn winding products and extracting defect detection results therefrom.

[0065] In the specific implementation of the above scheme, appearance defect recognition uses a high-resolution camera and image processing software to identify appearance defects of the yarn on the reel, such as knots, tangles or uneven colors, and the defect detection results extracted therefrom include defect type, defect area, and defect distribution area.

[0066] The finished yarn winding product is measured by using a diameter sensor and a thickness measuring instrument to obtain the diameter and wall thickness of the finished yarn winding product.

[0067] The finished yarn winding product is focused on the wound winding area, which is recorded as the effective winding area, and then the winding density of each effective winding area is tested for uniformity. The specific detection method is to compare the winding density of each effective winding area, extract the maximum winding density and make a difference therefrom to obtain the maximum winding density difference.

[0068] The defect detection results, size detection results, and uniformity detection results constitute a winding quality detection result set for the finished yarn winding product.

[0069] The winding qualified evaluation module is used to perform qualified evaluation based on the winding quality test results using an alarm device. The specific evaluation is to compare the winding quality test results with the configured qualified winding quality test results. If any test result does not reach the qualified winding quality test result, the alarm device is used to issue an alarm and display the test result at the same time.

[0070] The present invention performs comprehensive quality inspections on the finished winding product in terms of appearance defects, size, and uniformity after the yarn is wound, which can avoid missed identification of quality defects in the finished winding yarn product, ensure the quality consistency of all wound finished products, and at the same time, can promptly discover and resolve quality problems, reduce subsequent rework and correction costs, and reduce overall production costs.

[0071] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
