Detailed Implementation

[0012] Please refer to Figure 1 This illustration shows a schematic diagram of an online yarn tension detection system according to an embodiment of this application. The yarn tension detection system may include a spinning machine 10 and a computer device 20.

[0013] Spinning machine 10 refers to equipment used for spinning yarn. Exemplarily, in the embodiments of this application, spinning machine 10 is a rotor spinning machine.

[0014] The computer device 20 is used to detect the tension of the yarn during the spinning process of the spinning machine 10. Exemplarily, the computer device 20 can be an electronic device such as a mobile phone, tablet computer, wearable device, backend server, server cluster, PC (Personal Computer), or controller mounted on the spinning machine 10, and this application embodiment does not limit it.

[0015] In this embodiment, a tension sensor is provided between the yarn guide roller and the yarn bobbin. A computer device acquires a first yarn guide speed of the yarn guide roller, which is the speed at which the yarn guide roller draws the yarn out of the yarn guide opening. Further, a test speed is determined based on the first yarn guide speed, which is greater than the first yarn guide speed. Further, during the yarn guide roller's yarn guiding process, yarn tension data is acquired based on the test speed and the tension sensor. Then, if the yarn tension data meets the requirements, it is determined that the yarn meets the production needs.

[0016] Optionally, the spinning machine 10 interacts with the computer device 20 via a network.

[0017] Please refer to Figure 2 The diagram illustrates a flowchart of an online yarn tension detection method provided in one embodiment of this application. This method is applied to... Figure 1 The computer device 20 in the yarn tension detection system shown. The method may include the following steps (201-204): Step 201: Obtain the first yarn feeding speed of the yarn feeding roller.

[0018] The first yarn feeding speed refers to the speed at which the yarn feeding roller draws the yarn out of the yarn feeding opening. The yarn feeding roller is the mechanical device that draws the yarn out of the yarn feeding opening. In this embodiment, when detecting yarn tension, the computer device acquires the first yarn feeding speed of the yarn feeding roller.

[0019] In one possible implementation, the first yarn feed speed is a fixed value during a complete spinning process. Alternatively, for a given spinning process, the computer device can acquire the first yarn feed speed at the start of spinning.

[0020] In another possible implementation, to reduce the influence of external factors such as the environment and improve the accuracy of the first yarn feeding speed, the computer device acquires the first yarn feeding speed in real time before acquiring the test speed. For example, the computer device determines the length of yarn drawn out by the yarn feeding roller per unit time based on the radius and rotational speed of the yarn feeding roller, and then determines the length of yarn drawn out by the yarn feeding roller per unit time as the first yarn feeding speed. The unit time can be any value; operators can flexibly set and adjust the unit time according to actual conditions, such as 1 millisecond, 1 second, etc., and this embodiment does not limit this.

[0021] Step 202: Determine the test speed based on the first yarn feeding speed.

[0022] In this embodiment of the application, after obtaining the first yarn feeding speed, the computer device determines the test speed based on the first yarn feeding speed. The test speed is greater than the first yarn feeding speed.

[0023] In one possible implementation, the test speed is a preset fixed value, and there is a correspondence between the first yarn feeding speed and the test speed. Optionally, the computer device uses the first yarn feeding speed as an index to retrieve the test speed corresponding to the first yarn feeding speed from a pre-stored correspondence.

[0024] In another possible implementation, the test speed is calculated in real time. Optionally, the relative speed between the test speed and the first yarn feeding speed is equal to a preset value. The computer device determines the test speed based on this preset value and the first yarn feeding speed. Here, the relative speed refers to the absolute value of the difference between the test speed and the first yarn feeding speed; that is, the test speed is the sum of the first yarn feeding speed and the relative speed. Optionally, the preset value can be any value, and can be flexibly set and adjusted according to actual conditions. This application embodiment does not limit this. For example, different production requirements for yarn correspond to different preset values.

[0025] Step 203: During the yarn feeding process of the yarn feeding roller, yarn tension data is acquired based on the test speed and tension sensor.

[0026] Optionally, the lead-in roller guides the yarn from the lead-in nozzle to the yarn bobbin, which is a container for storing yarn. Generally, the process of winding yarn onto the yarn bobbin can be called the winding process.

[0027] In this embodiment, a tension sensor is installed between the yarn guide roller and the yarn bobbin. After acquiring the aforementioned test speed, the computer device acquires yarn tension data based on the test speed and the tension sensor during the yarn guide roller's operation. The yarn tension data refers to the peak tension the yarn experiences when it breaks. For example, the yarn tension data can be understood as the maximum tensile force the yarn withstands when it breaks.

[0028] It should be noted that when acquiring yarn tension data based on the test speed and tension sensor, the yarn guide roller is still in operation, meaning the spinning machine has not stopped.

[0029] Optionally, in order to improve the accuracy of yarn tension detection, during the yarn feeding process of the feed roller, the computer device performs more than one operation of "acquiring yarn tension based on test speed and tension sensor" to obtain more than one candidate yarn tension data. Then, the more than one candidate yarn tension data is averaged to obtain the average yarn tension value.

[0030] Step 204: If the yarn tension data meets the requirements, determine that the yarn meets the production needs.

[0031] In this embodiment of the application, after obtaining the above-mentioned yarn tension data, the computer device determines that the yarn meets the production requirements if the yarn tension meets the requirements.

[0032] For example, the requirement is greater than a preset threshold. Optionally, if the yarn tension data is greater than the preset threshold, the computer device determines that the yarn meets production requirements, that is, the yarn quality meets production requirements. The preset threshold can be any value, and can be flexibly set and adjusted according to actual conditions; this application embodiment does not limit this.

[0033] In summary, the technical solution provided in this application determines the test speed by using a first yarn-feeding speed. Then, based on this first yarn-feeding speed, a tension sensor located between the yarn-feeding roller and the yarn bobbin acquires yarn tension data. If the yarn tension data meets the requirements, the yarn is deemed to meet production needs, thus achieving automated online yarn tension detection, which helps save manpower. Furthermore, by detecting yarn tension during the yarn-feeding process of the yarn-feeding roller, online yarn tension detection is achieved. Timely detection of yarn quality during the spinning process helps to promptly identify yarn quality issues caused by sudden customer factors such as equipment or environment, thereby indirectly improving the quality of spun products. Moreover, real-time online yarn tension detection eliminates the need for additional spindle stop operations, avoiding capacity losses caused by spindle stoppages, saving time, and improving yarn spinning efficiency.

[0034] In addition, the relative speed between the test speed and the first yarn feeding speed is equal to the preset value. The test speed is easy to obtain and can be done in real time, which improves the timeliness and accuracy of yarn tension detection.

[0035] The following section provides a detailed introduction to the methods for obtaining yarn tension data.

[0036] In an exemplary embodiment, step 203 above includes the following steps: 1. During the yarn feeding process of the yarn feeding roller, increase the winding speed to the test speed.

[0037] In this embodiment, after obtaining the aforementioned test speed, the computer device increases the winding speed to the test speed during the yarn feeding process of the yarn feeding roller. Optionally, the winding speed is controlled by the winding roller, and the computer device controls the winding speed to be increased to the test speed based on a speed control command for the winding roller. This speed control command is generated by the computer device and is used to control the winding roller to increase the winding speed to the test speed; the winding roller is used to wind the yarn onto the yarn bobbin.

[0038] The winding speed refers to the speed at which the yarn is wound onto the yarn bobbin. Optionally, in this embodiment, the winding speed can be understood as the yarn extraction speed between the yarn guide roller and the yarn bobbin; correspondingly, the aforementioned first yarn guide speed can be understood as the yarn extraction speed between the yarn guide opening and the yarn guide roller. The winding speed is less than the test speed.

[0039] In one possible implementation, the winding speed is equal to the first yarn feeding speed.

[0040] In another possible implementation, to prevent excessive yarn entanglement between the yarn guide roller and the yarn bobbin, the winding speed is slightly greater than the first yarn guide speed. That is, the winding speed is greater than the first yarn guide speed, and the ratio between the first yarn guide speed and the winding speed is greater than a preset target value. For example, this preset target value can be any value, and operators can flexibly set and adjust it according to actual conditions, such as 0.97, 0.98, 0.99, etc. This application embodiment does not limit this.

[0041] Optionally, in this embodiment, the computer device increases the winding speed to the test speed when the duration between the current moment and the first moment is greater than the interval duration. For example, the computer device generates the aforementioned speed control command when the duration between the current moment and the first moment is greater than the interval duration. Here, the first moment refers to the moment adjacent in time when the winding speed was last increased to the test speed. That is, the computer device intermittently detects the yarn tension based on the interval duration. The interval duration can be any value, and operators can flexibly set and adjust it according to actual conditions, such as 30 minutes, one hour, 5 hours, 10 hours, etc. This embodiment does not limit this.

[0042] 2. The data recorded by the tension sensor when the yarn breaks between the yarn guide roller and the yarn bobbin is determined as the yarn tension data.

[0043] In this embodiment of the application, after the winding speed is increased to the test speed, the computer device determines the data recorded by the tension sensor when the yarn breaks between the yarn guide roller and the yarn bobbin as the yarn tension data.

[0044] For example, such as Figure 3 As shown, a tension sensor 33 and a winding roller 34 are arranged between the yarn guide roller 31 and the yarn bobbin 32. During the spinning process, the yarn guide roller 31 draws the yarn 35 out from the yarn guide opening at a first yarn guide speed. Further, the winding roller 34 winds the yarn 35 onto the yarn bobbin 32 at a winding speed (i.e., the yarn guide speed between the yarn guide roller 31 and the winding roller 34 is the winding speed). Furthermore, during the yarn guide process of the yarn guide roller 31, the computer equipment determines a test speed based on the first yarn guide speed and adjusts the winding speed to the test speed. Correspondingly, the winding roller 34 adjusts its winding speed to the test speed. Then, the data recorded by the tension sensor 33 when the yarn 35 breaks between the yarn guide roller 31 and the yarn bobbin 32 (i.e., the yarn guide roller 31 and the winding roller 34) is determined as yarn tension data.

[0045] In summary, the technical solution provided in this application embodiment increases the winding speed to the test speed during the yarn feeding process of the yarn feeding roller, and then determines the data recorded by the tension sensor when the yarn breaks between the yarn feeding roller and the yarn bobbin as yarn tension data, thereby realizing online automated yarn tension detection, which is simple to operate and saves manpower.

[0046] In addition, if the duration between the current moment and the first moment is greater than the interval duration, the winding speed is increased to the test speed. The first moment refers to the moment when the winding speed was last increased to the test speed, which is adjacent in time. In other words, the yarn tension is intermittently tested based on the interval duration, which further improves the accuracy of yarn tension testing.

[0047] Please refer to Figure 4 This illustrates a flowchart of an online yarn tension detection method provided in another embodiment of this application. The method is applied to... Figure 1 The computer device 20 in the yarn tension detection system shown. The method may include the following steps (401-406): Step 401: Obtain the first yarn feeding speed of the yarn feeding roller.

[0048] Step 402: Determine the test speed based on the first yarn feeding speed.

[0049] Step 403: During the yarn feeding process of the yarn feeding roller, yarn tension data is acquired based on the test speed and tension sensor.

[0050] Step 404: If the yarn tension data meets the requirements, determine that the yarn meets the production needs.

[0051] Steps 401-404 above and Figure 2 Steps 201-204 in the embodiment are similar; see details below. Figure 2 Examples are not detailed here.

[0052] Step 405: If the yarn tension data does not meet the requirements, determine the target length of the yarn that does not meet the production requirements from the yarn that has been wound onto the yarn bobbin.

[0053] In this embodiment of the application, after obtaining the above-mentioned yarn tension data, if the yarn tension data does not meet the above requirements, the computer device determines the target length of the yarn that does not meet the above production requirements from the yarn that has been wound onto the yarn bobbin.

[0054] Optionally, if the yarn tension data does not meet the above requirements, the computer device acquires a second moment. The second moment refers to the moment adjacent in time when it was previously determined that the yarn met production requirements. For example, for the first moment, if the yarn tension data obtained after increasing the winding speed to the test speed at the first moment meets the requirements, then the second moment is the same as the first moment.

[0055] Optionally, after obtaining the second moment mentioned above, the computer device determines the target length based on the duration between the current moment and the second moment, combined with the winding speed mentioned above. Here, the yarn that does not meet production requirements refers to yarn whose length, starting from the end of the yarn currently wound onto the bobbin, is equal to the target length.

[0056] Step 406: Issue a warning message.

[0057] In this embodiment of the application, after obtaining the target length, the computer device issues a warning message. This warning message is used to indicate that the yarn of the target length does not meet production requirements.

[0058] Optionally, the warning information can be sent to the spinning machine or to the operator's device (such as a mobile phone, walkie-talkie, etc.). In one possible implementation, the computer device sends the warning information to the spinning machine, and the spinning machine further issues a broadcast message based on the warning information. The broadcast message includes information related to the target length contained in the warning information. For example, the broadcast message is audio information. In another possible implementation, the computer device sends the warning information to the operator's device, and the operator further processes the yarn that does not meet the target length required for production based on the warning information.

[0059] In one possible implementation, the warning information includes the target length. For example, the target length-related information included in the warning information refers to the target length itself.

[0060] In another possible implementation, the warning information includes the starting position and target length of the yarn that has not met production requirements. Optionally, since workers cannot process the yarn that has not met the target length in a timely manner, the computer device calculates the length of the yarn wound at the second moment based on the winding time and winding speed, and then determines the length of the yarn wound at the second moment as the starting position. Based on this starting position and the target length, a warning message is generated and issued. For example, the information related to the target length included in the warning information refers to the starting and ending positions of the yarn that has not met production requirements.

[0061] In summary, the technical solution provided in this application, when the yarn tension data does not meet the requirements, determines the target length of the yarn that does not meet the production needs from the yarn already wound onto the yarn bobbin, and then issues an early warning message to indicate that there are yarns of the target length that do not meet the production needs. Timely recording and warning of the target length of the yarn that does not meet the production needs is beneficial for subsequent processing of the problematic yarn, and thus helps to retain as much yarn as possible that meets the production needs in the same yarn bobbin. The operation is simple and saves resources.

[0062] Furthermore, the target length is determined by combining the time between the current moment and the second moment with the winding speed. Moreover, the yarn that does not meet production requirements refers to the yarn whose length is equal to the target length, starting from the end of the yarn currently wound onto the yarn bobbin. In other words, even if the quality of some yarns changes due to machine failure or other reasons at the same spinning speed, the target length of the yarn that does not meet production requirements can be easily detected and marked based on the detection results. This approach is reasonable, simple, and retains as much yarn as possible that meets production requirements, which is beneficial for saving yarn resources.
