A misaligned winding method for waste yarn at the bottom of a flyer roving bobbin

Abstract

This application relates to the technical field of spinning frames, and particularly to a misaligned winding method for waste yarn on the spindles of a spinning frame's doffing system. By setting M waste yarn winding positions and using different positions for misaligned winding of waste yarn from different doffing cycles, it is possible to ensure that the waste yarn from at least M doffing cycles does not overlap, reducing the problem of the waste yarn from the current doffing cycle bundling the waste yarn from the next doffing cycle, making the thickness of the waste yarn at the winding position thinner. In this way, when the spindle rotates at high speed, under the interference of air resistance, the waste yarn from the previous doffing cycle is more likely to fly off naturally, reducing the overlapping and piling up of waste yarn, thereby achieving both a reduction in broken ends and a reduction in waste yarn.

Description

Technical Field

[0001] This application relates to the technical field of spinning frames, and particularly to a misaligned winding method for the waste yarn at the spindle base of a spinning frame with a collective doffing system. Background Art

[0002] For a long time, all spindles with aluminum sleeves or polished rods have faced a structural problem that has troubled the industry, that is, it is difficult to remove the waste yarn at the spindle base after full bobbin doffing. The waste yarn at the spindle base is a key link for high-efficiency spinning at the beginning of the next doffing. If the waste yarn is wound tightly, the number of start-up breakages during the next spinning process will be reduced; otherwise, there will be more breakages. The tight winding is ensured by the number of winding turns. The more turns, the tighter. However, the contradiction is that the more winding turns, the more difficult it is to throw off the waste yarn during the spinning production process of the next doffing, resulting in more and more waste yarn accumulating. To a certain extent, it is necessary to stop the machine for manual cleaning, which is time-consuming and laborious, with low efficiency and affecting the workshop output.

[0003] In related technologies, generally, the number of winding turns is set to 3 - 5 turns based on empirical values, so that the waste yarn can be thrown off while being wound tightly. However, in fact, when the number of winding turns exceeds 3.5 turns, it is difficult to automatically throw off the waste yarn, and there is still a situation where the waste yarn accumulates more and more. In some foreign manufacturers, by setting a waste yarn clamping device, when the spindle speed is lower than the preset speed during doffing, the waste yarn clamping device is controlled to open, and after winding one turn, it automatically closes to clamp the waste yarn at the end of the yarn. When the machine starts up for the next doffing and the speed reaches a certain speed, the device opens again to make the waste yarn fly off automatically. However, after the device has been running for 3 to 4 years, its reliability decreases, and the spindle speed matching is poor. Some open and some do not open, resulting in a significant increase in breakages, and this situation needs to be further improved. Summary of the Invention

[0004] In order to solve the problem that it is difficult to balance reducing breakages and reducing waste yarn in the existing spinning production process, this application provides a misaligned winding method for the waste yarn at the spindle base of a spinning frame with a collective doffing system, and adopts the following technical solutions:

[0005] In a first aspect, this application provides a misaligned winding method for the waste yarn at the spindle base of a spinning frame with a collective doffing system, which is applied to a spinning frame. The method includes the following steps:

[0006] Judge whether N spindles are full of yarn in the current cycle, where N is an integer greater than or equal to 1;

[0007] If it is detected that the N spindles are full of yarn, determine the target winding position corresponding to the target doffing. The target doffing is the current doffing of any one of the N spindles, and the target winding position is any one of the M winding positions provided on the target waste winding part. The target waste winding part is the waste winding part corresponding to the target doffing among the N waste winding parts provided on the ring spinning frame. The waste winding part is provided on the spindle, and M is an integer greater than or equal to 2;

[0008] Wind the waste yarn corresponding to the target doffing to the target winding position.

[0009] By adopting the above technical solution, in the related art, all spindle feet have only one waste yarn winding position, which will not be changed after being adjusted. Compared with the related art where there is only one waste yarn winding position, the present application sets M waste yarn winding positions. When it is detected that the doffing is full of yarn, first determine a target waste yarn winding position from the M waste yarn winding positions. Since the waste yarns of different doffing times in the present application are wound in a staggered manner at different positions, at least M doffing times of waste yarns can be made non-overlapping, reducing the problem of the waste yarn of this doffing bundling the waste yarn of the next doffing, making the waste yarn thickness of each doffing thinner. In this way, when the spindle rotates at high speed, under the interference of air resistance, the waste yarn of the previous doffing is more likely to fly off naturally, reducing the accumulation of waste yarn, so as to reduce broken ends and waste yarn at the same time.

[0010] Optionally, the determining the target winding position corresponding to the target doffing includes the following steps:

[0011] Determine the waste yarn winding number corresponding to the target doffing;

[0012] Determine the winding position corresponding to the waste yarn winding number on the target waste yarn winding part;

[0013] Determine the winding position as the target winding position.

[0014] By adopting the above technical solution, the present application sets a waste yarn winding number for each target doffing, then determines the winding position corresponding to the waste yarn winding number on the target waste yarn winding part, and determines the winding position as the target winding position. Therefore, each target doffing can be wound at the corresponding target winding position according to the waste yarn winding number. For example, the waste yarn winding position of the first batch of doffing with the waste yarn winding number of 1 is set at -3 mm, the second batch of doffing with the waste yarn winding number of 2 is set at -6 mm, and the third batch of doffing with the waste yarn winding number of 3 is set at -9 mm (the spindle waste yarn range is usually 0~-11 mm); then cycle repeatedly, so as to realize the staggered winding of each batch of target doffing.

[0015] Optionally, the determining the target winding position corresponding to the target doffing includes the following steps:

[0016] Determine the free winding position of the waste yarn on the target waste yarn winding part;

[0017] Determine the free winding position as the target winding position.

[0018] By adopting the above technical solution, in an embodiment of the present application, the present application determines the free winding position of the waste yarn on the target waste yarn winding part and determines the free winding position as the target winding position. Therefore, when the yarn falling is wound on multiple winding positions, the waste yarn of the current lot can be wound on the free winding position, reducing the situation that some winding positions are free while the waste yarn of the current lot binds the waste yarn of the previous lot on some other winding positions.

[0019] Optionally, determining the target winding position corresponding to the target yarn falling includes the following steps:

[0020] Judge whether there is a free winding position of the waste yarn on the target waste yarn winding part;

[0021] If there is no free winding position of the waste yarn on the target waste yarn winding part, determine the waste yarn thickness of each winding position among the M winding positions on the target waste yarn winding part;

[0022] Determine the target winding position from the M winding positions according to the waste yarn thickness.

[0023] By adopting the above technical solution, when at least one cycle is completed and there is waste yarn remaining on each winding position that has not been thrown off, the present application first judges whether there is a winding position of the waste yarn on the target waste yarn winding part. When there is no free winding position of the waste yarn on the target waste yarn winding part, determine the waste yarn thickness of each winding position among the M winding positions on the waste yarn winding part, and then determine the winding position with the thinnest waste yarn thickness as the target winding position, thereby preventing the waste yarn thickness at a certain winding position from being too large.

[0024] Optionally, determining the target winding position corresponding to the target yarn falling includes the following steps:

[0025] Judge whether the number of waste yarn winding parts with the same free position among the N waste yarn winding parts reaches a preset number threshold, where the same free position is any one of the M winding positions;

[0026] If so, determine the same free position as the target winding position.

[0027] By adopting the above technical solution, since there are N spindles on the spinning frame, generally 500 - 1000 spindles, the degree of waste yarn shedding on different spindles is different. In this application, by judging whether the number of waste yarn winding parts with the same idle position among the N waste yarn winding parts reaches a preset number threshold, when the preset number threshold is reached, the same idle position is determined as the target winding position. For example, the preset number threshold is 150. Among the waste yarn winding parts of 500 spindles, 300 are idle at -3 mm, exceeding the preset number threshold, and the remaining 200 are idle at -6 mm and -9 mm. Then, the position of -3 mm is determined as the target winding position, so that the waste yarn on most spindles can be wound at the idle winding position.

[0028] Optionally, the steps for determining the waste yarn winding number corresponding to the target doffing include the following:

[0029] If it is detected that the N doffings are full of yarn, count the number of times of full - yarn doffing in the current operation process to obtain a counting result;

[0030] Determine the waste yarn winding number corresponding to the current target doffing according to the counting result.

[0031] By adopting the above technical solution, in this application, when it is detected that the doffing is full of yarn, the doffing in the current operation process is counted to obtain a counting result, and then the waste yarn winding number corresponding to the current target doffing is determined according to the counting result, so as to realize the automatic numbering of each batch of doffings.

[0032] Optionally, the method further includes:

[0033] Provide a first cutting device, which is arranged on the waste yarn winding part;

[0034] If it is detected that the waste yarn winding corresponding to the target doffing is completed, control the first cutting device to perform the operation of cutting the target doffing.

[0035] By adopting the above technical solution, this application provides a first cutting device, which is arranged on the waste yarn winding part. When it is detected that the waste yarn winding corresponding to the target doffing is completed, control the first cutting device to perform the operation of cutting the target doffing to complete the collection of a batch of doffings and start the spinning of the next batch of doffings.

[0036] Optionally, the method further includes;

[0037] Provide a target air outlet, which is arranged at the target winding position;

[0038] If it is detected that the current cycle is completed, or the thickness of the waste yarn at the target winding position reaches a preset thickness threshold, then control the target air outlet to operate so as to separate the waste yarn at the target winding position.

[0039] By adopting the above technical solution, the present application provides a target air outlet which is arranged at the target winding position. If it is detected that a cycle is completed, or the thickness of the waste yarn at the target winding position reaches a preset thickness threshold, then control the target air outlet to operate so as to separate the waste yarn at the target winding position, thereby preventing the thickness of the overlapping winding of the waste yarn from being too large.

[0040] In a second aspect, the present application provides a misaligned winding system for the waste yarn of the flyer frame doffer leg, including:

[0041] A judgment module, which is used to judge whether N spindles are full of yarn within the current cycle.

[0042] A determination module, which is used to determine the target winding position corresponding to the target doffing when it is detected that N spindles are full of yarn. The target doffing is the current doffing of any one of the N spindles, and the target winding position is any one of the M waste yarn winding positions arranged on the target waste yarn winding part. The target waste yarn winding part is the waste yarn winding part corresponding to the target doffing among the N waste yarn winding parts arranged on the flyer frame. The waste yarn winding part is arranged on the spindle, and M is an integer greater than or equal to 2.

[0043] In a third aspect, the present application provides a computer device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned misaligned winding method for the waste yarn of the flyer frame doffer leg are implemented.

[0044] In a fourth aspect, the present application provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the above-mentioned misaligned winding method for the waste yarn of the flyer frame doffer leg are implemented.

[0045] In summary, the present application includes at least one of the following beneficial technical effects:

[0046] Compared with the related art in which there is only one waste yarn winding position, the present application arranges M waste yarn winding positions. Since the waste yarn of different doffing times in the present application is misaligned and wound at different positions, at least M doffing times of waste yarn can be made non-overlapping, reducing the problem that the waste yarn of this doffing binds the waste yarn of the next doffing, making the thickness of the waste yarn at the winding position thinner. In this way, when the spindle rotates at a high speed, under the interference of air resistance, the waste yarn of the previous doffing is more likely to fly off naturally, reducing the accumulation of waste yarn, thereby reducing broken ends and waste yarn;

[0047] By determining the idle winding position on the target waste yarn winding part and designating it as the target winding position, when multiple winding positions are all wound with doffing yarns, the waste yarn of the current doffing can be wound on the idle winding position, reducing the situation where some winding positions are idle while on some other winding positions, the waste yarn of the current doffing binds the waste yarn of the previous doffing.

[0048] After at least one cycle, the application first checks whether there is a waste yarn winding position on the target waste yarn winding part. When there is no idle waste yarn winding position on the target waste yarn winding part, it determines the waste yarn thickness of each of the M waste yarn winding positions on the waste yarn winding part, and then designates the winding position with the thinnest waste yarn thickness as the target winding position, thus preventing the waste yarn thickness at a certain winding position from being too large.

[0057] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the", "above-mentioned", "said", and "this" are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in the present application refers to any or all possible combinations including one or more of the listed items.

[0058] Hereinafter, the terms "first" and "second" are only for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0059] In the related art, there is generally only one winding position for the waste yarn at the spindle base of the ring spinning frame. After being adjusted, it will not be changed anymore. The winding turns of the waste yarn are set to 3 - 5 turns through empirical values to ensure that the waste yarn is automatically thrown off during the rotation of the spindle while the winding is relatively tight. However, there is still a problem that it is difficult to be automatically thrown off in a short time, resulting in the accumulation of more and more waste yarn. To a certain extent, it is necessary to stop the machine for manual cleaning.

[0060] In view of this, the embodiments of the present application provide a misaligned winding method for the waste yarn at the spindle base of the ring spinning frame with a doffing system. By setting M winding positions for the waste yarn and adopting different positions for misaligned winding of the waste yarn in different doffing times, it is possible to achieve that the waste yarn of at least M doffing times does not overlap, reducing the problem of the waste yarn of this doffing bundling the waste yarn of the next doffing, thereby taking into account reducing breakage and reducing waste yarn.

[0061] The following will explain a misaligned winding method for the waste yarn at the spindle base of the ring spinning frame with a doffing system provided by the present application from the perspective of the ring spinning frame.

[0062] Please refer to Figure 1 , Figure 1 , which is an exemplary flowchart of a method for winding the waste yarn at the spindle base of the ring spinning frame with a doffing system according to an embodiment of the present application.

[0063] A misaligned winding method for the waste yarn at the spindle base of the ring spinning frame with a doffing system includes the following steps:

[0064] S110. Determine whether N spindles are full of yarn within the current cycle.

[0065] Among them, N doffings correspond to N spindles provided on the ring spinning frame, and N is an integer greater than or equal to 1; the spindles can be aluminum sleeve spindles, bare shaft spindles, etc., which are not limited here. Specifically, multiple spindles are provided on a ring spinning frame of general scale (for example, 500, and of course, it can also be adjusted according to actual situations, and no specific limitation is made). When each batch of doffings winds to a preset length, it is full yarn. At this time, the waste yarn of this doffing needs to be wound, and then this doffing is collected, and then the next doffing is wound.

[0066] S120. If it is detected that the N spindles are full of yarn, determine the target winding position corresponding to the target doffing.

[0067] Among them, the target doffing is the current doffing of any one of the N spindles, the target winding position is any one of the M waste yarn winding positions provided on the target waste yarn winding part, the target waste yarn winding part is the waste yarn winding part corresponding to the target doffing among the N waste yarn winding parts provided on the ring spinning frame, the waste yarn winding part is provided on the spindle, and M is an integer greater than or equal to 2.

[0068] Specifically, the target winding position can be processed through big data, select a waste yarn winding part with the worst waste yarn throwing from the N waste yarn winding parts, and determine the waste yarn winding part with the worst waste yarn throwing as the target waste yarn winding part. It can also be preset one, or receive the operation instruction of the user, and determine a target waste yarn winding part from the N waste yarn winding parts according to the operation instruction.

[0069] In the related art, there is only one waste yarn winding position, generally 5 mm below the zero position, and the zero position refers to the lowest winding position of the doffing. In this application, M winding positions are set. For example, M is equal to 3, that is, there are 3 waste yarn winding positions on the waste yarn winding part. For example, they are set at -3 mm, set at -6 mm, and set at -9 mm respectively (the waste yarn range of the spindle is usually 0~-11 mm). Then the first batch of doffings is wound at -3 mm, the second batch of doffings is wound at -6 mm, the third batch of doffings is wound at -9 mm, and then it circulates. The fourth batch of doffings is wound at -3 mm again, so that each batch of target doffings realizes staggered winding, reducing the problem of the waste yarn of this doffing bundling the waste yarn of the next doffing, making the waste yarn thickness of each doffing thinner. In this way, when the spindle rotates at high speed, under the interference of air resistance, the waste yarn of the previous doffing is more likely to fly off naturally, reducing the accumulation of waste yarn, so as to reduce broken ends and waste yarn at the same time.

[0070] To realize the M winding positions, a winding contact surface needs to be set and a certain friction force needs to be provided. Refer to Figure 2 , Figure 2 is a schematic understanding diagram of improving the spindle in the embodiment of this application. As Figure 2As shown in the figure, the existing spindle has only one winding position. A base is installed on the spindle of the spinning frame of the present application, and a steel sleeve (i.e., the waste yarn winding part) is installed on the base. Knurling is used on the steel sleeve to enhance the friction force. The steel sleeve is provided with a first waste yarn winding position, a second waste yarn winding position, and a third waste yarn winding position to achieve staggered winding of different batches of doffing; for easy understanding, Figure 2 The corresponding physical pictures are given in the following part.

[0071] In order to facilitate the collection of a batch of doffing after the waste yarn winding is completed, the present application also provides a first cutting device, which is arranged on the waste yarn winding part. When it is detected that the waste yarn winding corresponding to the target doffing is completed, the first cutting device is controlled to perform the operation of cutting the target doffing. Further, a protective cover is provided on the first cutting device to prevent the doffer from being cut when dealing with broken ends and waste yarn.

[0072] When the spinning frame determines the target winding position corresponding to the target doffing, it can be determined in a variety of ways, which are described separately below:

[0073] E1. Determine by the waste yarn winding number.

[0074] Refer to Figure 3 , Figure 3 This is an exemplary flowchart for determining the target winding position by the waste yarn winding number in an embodiment of the present application.

[0075] S121a. Determine the waste yarn winding number corresponding to the target doffing.

[0076] Among them, a waste yarn winding number is set for each batch of target doffing to control the winding position of the target doffing. For example, when it is detected that N doffings are full of yarn, the number of times of full doffing in the current operation process is counted, and the waste yarn winding number corresponding to the current target doffing is determined according to the counting result to achieve automatic numbering.

[0077] S121b. Determine the winding position corresponding to the waste yarn winding number on the target waste yarn winding part.

[0078] Among them, the winding position corresponding to the waste yarn winding number 1 is at -3 mm, the winding position corresponding to the waste yarn winding number 2 is at -6 mm, and the winding position corresponding to the waste yarn winding number 3 is at -9 mm (the waste yarn range of the spindle is usually 0~-11 mm); then it repeats, the winding position corresponding to the waste yarn winding number 4 is at -3 mm, and so on.

[0079] S121c. Determine the winding position as the target winding position.

[0080] In this embodiment, by pre-corresponding the numbers and winding positions, and determining the number corresponding to the target doffing, the corresponding winding position is determined as the target winding position, so as to realize the automatic and orderly misaligned winding of the waste yarn for each batch of doffing.

[0081] E2. Determine by the idle waste yarn winding position.

[0082] Refer to Figure 4 , Figure 4 which is an exemplary flowchart for the present application to determine the target winding position by the idle waste yarn winding position.

[0083] S122a. Determine the idle waste yarn winding positions on the target waste yarn winding part.

[0084] Wherein, the present application provides a camera for determining the idle waste yarn winding positions on the target waste yarn winding part. For example, when there is waste yarn winding at both -3 mm and -6 mm and it has not been thrown off, and there is no waste yarn winding at -9 mm, determine -9 mm as the idle waste yarn winding position.

[0085] S122b. Determine the idle waste yarn winding position as the target winding position.

[0086] In this embodiment, by determining the idle waste yarn winding positions on the target waste yarn winding part and determining the idle waste yarn winding position as the target winding position, when there is doffing wound at multiple winding positions, the waste yarn of this doffing can be wound on the idle winding positions, reducing the situation that some winding positions are idle while some winding positions have the waste yarn of this doffing bundling the waste yarn of the previous doffing.

[0087] E3. Determine by the waste yarn thickness.

[0088] Refer to Figure 5 , Figure 5 which is an exemplary flowchart for the embodiment of the present application to determine the target winding position by the waste yarn thickness.

[0089] S123a. Judge whether there are idle waste yarn winding positions on the target waste yarn winding part.

[0090] S123b. If there are no idle waste yarn winding positions on the target waste yarn winding part, determine the waste yarn thickness of each of the M waste yarn winding positions on the target waste yarn winding part.

[0091] S123c. Determine the target winding position from the M waste yarn winding positions according to the waste yarn thickness.

[0092] Among them, the winding position with the thinnest waste yarn thickness is determined as the target winding position from M waste yarn winding positions according to the waste yarn thickness. This application provides a thickness sensor for detecting the waste yarn thickness at the waste yarn winding position. For example, when at least one cycle is completed and there is waste yarn remaining at each waste yarn winding position, the waste yarn thickness at -3 mm and -6 mm is 1 mm, and the waste yarn thickness at -9 mm is 0.5 mm, then -9 mm is determined as the target winding position.

[0093] In this embodiment, by judging whether there is a waste yarn winding position on the target waste yarn winding part, when there is no idle waste yarn winding position, the waste yarn thickness at each waste yarn winding position is determined, and then the winding position with the thinnest waste yarn thickness is determined as the target winding position, thereby preventing the waste yarn thickness at a certain winding position from being too large.

[0094] E4. Determine by the number of waste yarn winding parts with the same position among multiple waste yarn winding parts.

[0095] Refer to Figure 6 , Figure 6 is an exemplary flowchart for determining the target winding position by the number of waste yarn winding parts with the same position in the embodiments of this application.

[0096] S124a. Judge whether the number of waste yarn winding parts with the same position among N waste yarn winding parts reaches a preset number threshold.

[0097] S124b. If so, determine the same idle position as the target winding position.

[0098] Among them, since there are N spindles on the spinning frame and the degree of waste yarn shedding on different spindles is different. For example, there are 500 spindles on the spinning frame, the preset number threshold is 150, and among the waste yarn winding parts of the 500 spindles, 300 are idle at -3 mm, exceeding the preset number threshold, and the remaining 200 are idle at -6 mm and -9 mm, then the position at -3 mm is determined as the target winding position.

[0099] In this embodiment, by judging whether the number of waste yarn winding parts with the same idle position among N waste yarn winding parts reaches a preset number threshold, when the preset number threshold is reached, the same idle position is determined as the target winding position, so that the waste yarn on most spindles can be wound at the idle winding position.

[0100] S130. Wind the waste yarn corresponding to the target doffing to the target winding position.

[0101] In some embodiments, the present application further provides a target air outlet, which is arranged at the target winding position. If it is detected that the current cycle is completed, or the thickness of the waste yarn at the target winding position reaches a preset thickness threshold, the operation of the target air outlet is controlled to separate the waste yarn at the target winding position, thereby preventing the thickness of the overlapping winding of the waste yarn from being too large. Specifically, the target air outlet can be a suction air outlet or a blowing air outlet to suck or blow the waste yarn away from the spindle.

[0102] It should be noted that the present application sets M suction air outlets / blowing air outlets for M waste yarn winding positions, so as to perform targeted suction / blowing on the waste yarn winding positions, and the target air outlet only operates when the conditions are met, reducing the situation of excessive machine power consumption caused by multiple suction air outlets / blowing air outlets running for a long time at the same time.

[0103] In some possible embodiments, the present application further provides a second cutting device, which corresponds to the target winding position. If it is detected that the current cycle is completed, or the thickness of the waste yarn at the target winding position reaches a preset thickness threshold, then when taking the yarn, when the spindle speed is lower than the preset speed threshold, the second cutting device is controlled to cut the waste yarn; when it is detected that the second cutting device cuts the waste yarn, the operation of the target air outlet is controlled, or the suction of the target air outlet is increased.

[0104] In the embodiments of the present application: the waste yarn at the target winding position is separated by the target air outlet, thereby preventing the thickness of the overlapping winding of the waste yarn from being too large.

[0105] In summary, in the embodiments provided by the present application, the flyer frame realizes that at least M waste yarns of M falling times do not overlap by setting M waste yarn winding positions, reducing the problem of the waste yarn of the current falling bundling the waste yarn of the next falling, making the thickness of the waste yarn at the winding position thinner. In this way, when the spindle rotates at a high speed, under the interference of air resistance, the waste yarn of the previous falling is more likely to fly off naturally, reducing the accumulation of waste yarn, and thus reducing both breakage and waste yarn.

[0106] In a second aspect, the present application provides a misaligned winding system for the waste yarn at the flyer frame doffer. The misaligned winding system for the waste yarn at the flyer frame doffer of the present application will be described below in combination with the above misaligned winding method for the waste yarn at the flyer frame doffer. Please refer to Figure 7 , Figure 7 which is a schematic diagram of the modules of a misaligned winding system for the waste yarn at the flyer frame doffer in an embodiment of the present application.

[0107] A misaligned winding system for the waste yarn at the flyer frame doffer includes:

[0108] A judgment module, configured to judge whether N spindles are full of yarn within the current cycle.

[0109] A determination module, configured to determine a target winding position corresponding to a target doffing when N spindles are detected to be full of yarn.

[0110] Wherein, the target doffing is the current doffing of any one of the N spindles, the target winding position is any one of the M winding positions provided on the target waste yarn winding part, the target waste yarn winding part is the waste yarn winding part corresponding to the target doffing among the N waste yarn winding parts provided on the spinning frame, the waste yarn winding part is provided on the spindle, and M is an integer greater than or equal to 2.

[0111] In one embodiment, the present application provides a computer device, which may be a server, and its internal structure diagram may be as Figure 8 shown. The computer device includes a processor, a memory, and a network interface connected through a system bus.
