Description

Technical Field

[0001] The invention relates to the technical field of cable cabling control, and in particular to a yarn binding tension control method for a cable cabling machine. Background Art

[0002] When producing cable cores, the yarn tension is usually controlled by the equipment control program. The control program of the existing cable production equipment is relatively complicated to control the yarn tension, and has the following defects: First, the number of parameters is too large and complicated: Seven parameters need to be adjusted for just one yarn: yarn tension correction, front-end yarn tension, yarn tension compensation coefficient at different speeds, yarn ball real-time coefficient, yarn tension compensation coefficient at start-up, yarn tension compensation coefficient at speed reduction, and yarn tension compensation coefficient at emergency stop. Among them, the yarn tension compensation coefficient at different speeds alone requires adjustment of dozens of parameters, which greatly increases the complexity and time cost of adjustment; Second, it is difficult to verify the adjustment effect: Due to the large number of parameters and their complex interactions, the effect of the adjustment is difficult to verify immediately in an intuitive way. As a result, when the yarn tension becomes abnormal, it takes a lot of time to adjust the parameters, test run and re-verify. Multiple parameters must be checked and adjusted one by one, forming a lengthy cycle, which greatly affects production efficiency. Summary of the invention

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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. Example

[0016] See also Figure 1 The present embodiment relates to a method for controlling the tension of a cable cabling machine, the method comprising the following steps: S1. Determine the tension correction coefficient A, which is used to adjust the basic tension setting value. The setting range of A is 0.1-3.0.

[0017] The tension correction coefficient A is set according to the outer diameter of the optical cable. The size of the tension correction coefficient A is proportional to the size of the outer diameter of the optical cable. The larger the outer diameter of the optical cable, the larger the tension correction coefficient A.

[0018] When the setting value of the tension correction coefficient A increases, the tension at the start-up (i.e. the initial stage of equipment startup) or low-speed operation will increase accordingly, which can ensure that the equipment maintains stable tension output during the startup stage and low-speed operation, and help reduce tension fluctuations caused by speed changes; At the same time, the tension correction coefficient A has a relatively small effect on the tension under high-speed operation, which can maintain the tension stability of the equipment during high-speed operation and avoid production problems caused by excessive or insufficient tension; This ensures that the cable cabling machine can maintain stable tension output under different operating conditions.

[0019] S2. Set the initial tension setting value B as the basis for subsequent tension calculation. The setting range of B is 0.1-300 to ensure the stability of tension control.

[0020] The tension setting value B is set according to the outer diameter of the optical cable. The size of the tension setting value B is proportional to the size of the outer diameter of the optical cable. The larger the outer diameter of the optical cable, the larger the tension setting value B.

[0021] When the setting value of the tension setting value B increases, the tension at the start-up (i.e. the initial stage of equipment startup) or low-speed operation will also increase accordingly, which can ensure that sufficient tension is maintained during the equipment startup stage or low-speed operation to avoid relaxation or deviation caused by insufficient tension; At the same time, the tension setting value B has a relatively small effect on the tension under high-speed operation. In this way, when the equipment reaches high-speed operation, even if the value of B is large, it will not cause a sharp increase in tension, thereby avoiding the risks caused by excessive tension.

[0022] S3. Calculate the static tension of the equipment when it is stationary or running at low speed by using the tension correction coefficient A and the tension setting value B. The calculation formula is: A×B×17.5, so as to ensure the precise control of the tension when it is stationary or running at low speed.

[0023] S4. Set the production speed C of the yarn binding to reflect the operating status of the equipment. It is set according to the characteristics of the equipment itself. The setting range of C is 2-100m / min. The faster the production speed, the greater the value of the production speed C, which provides a key basis for the adjustment of dynamic tension. S5. Determine the tension speed coefficient D so that the tension can be dynamically fine-tuned with the speed change. The setting range of D is 0.1-3.0.

[0024] The tension speed coefficient D is set according to the outer diameter of the optical cable. The size of the tension speed coefficient D is proportional to the size of the outer diameter of the optical cable. The larger the outer diameter of the optical cable, the larger the tension speed coefficient D. When the setting value of the tension speed coefficient D increases, the tension of the equipment will increase accordingly when it is running at high speed, which helps to maintain stability and tension consistency during high-speed production, thereby avoiding the problem of tension drop caused by increased speed; at the same time, since the tension speed coefficient D has little effect on low-speed operation, it will not interfere with the tension control of the equipment at low speed or startup stage.

[0025] S6. Calculate the dynamic tension of the equipment when it is running or accelerating by using the production speed C and the tension speed coefficient D. The calculation formula is: C×D×0.15, to ensure accurate control of the tension when running at high speed or accelerating.

[0026] S7. Set the yarn length coefficient E according to the actual length of the yarn to adapt to different yarn lengths: the output range of E is 0.7-1.1 to ensure the comprehensiveness and adaptability of tension control.

[0027] Preferably, when the yarn binding length is 35 km, the yarn binding length coefficient E is set to 1.1; when the yarn binding length is 30 km, the yarn binding length coefficient E is set to 1.0.

[0028] The yarn length coefficient E is dynamically adjusted according to the actual yarn length: when there are more remaining yarns, the value of coefficient E will increase accordingly, resulting in increased tension, which helps to ensure that the tension can be kept within the appropriate range at different stages of yarn production, thereby avoiding excessive or insufficient tension from adversely affecting the production process and product quality.

[0029] S8. Calculate the final output tension of the yarn binding by using the static tension, the dynamic tension and the yarn binding length coefficient E, and the calculation formula is: [(A×B×17.5)+(C×D×0.15)]×E.

[0030] In the initial stage, the tension correction coefficient A, tension setting value B, and tension speed coefficient D are preliminarily set according to the optical cable specifications and production conditions. These settings are based on empirical values ​​and standard operations and provide a benchmark for subsequent fine-tuning.

[0031] After the initial setup, precise tension control can be achieved by fine-tuning the various parameters. This fine-tuning is based on real-time feedback and observation to ensure that the yarn tension remains within the ideal range at high speeds and when speeds are increased or decreased.

[0032] Treatment of abnormal yarn binding tension at high speed: When abnormal yarn binding tension is detected during high-speed production, it is optimized by adjusting the tension speed coefficient D. If the yarn is too tight, reduce the value of the tension speed coefficient D; if the yarn is too loose, increase the value.

[0033] Handling of abnormal tension during low-speed operation / start-up: If the tension is abnormal during low-speed operation or startup, it is necessary to adjust the tension correction coefficient A and the tension setting value B. If the tension is too tight, reduce the tension correction coefficient A and the tension setting value B. If the tension is too loose, increase the tension correction coefficient A and the tension setting value B.

[0034] This sophisticated and efficient tension control method ensures the quality stability of cable products at different production speeds, while significantly improving the operating efficiency of technicians and the response speed of the production line: A fiber optic cable of a certain specification usually only needs to be fine-tuned 2-3 times to find the appropriate tension setting. The effect can be quickly verified after each adjustment to ensure the accuracy of tension control. This adjustment process greatly shortens the debugging time, which usually does not exceed 5 minutes, greatly improving the work efficiency of technicians and the overall production process efficiency. Example

[0035] Taking the production of GYTS-24 core optical cable as an example, the specific tension control parameters are set as follows: According to the production requirements and equipment capacity of GYTS-24 core optical cable, the production speed C is determined to be 70 m / min; Set the tension correction coefficient A to 1.8-3.0 to meet the specific tension requirements of GYTS-24 core optical cable during the production process and to fine-tune the tension setting value B; The tension setting value B is 60-90 to ensure that when producing GYTS-24 core optical cable, the cable will not be damaged due to excessive tension, nor will the cable shape be unstable due to too little tension; Set the tension speed coefficient D to 0.5-1.5 to fine-tune the tension according to the production speed C to maintain tension stability and consistency during high-speed production; The yarn binding length coefficient E is set to 1.1, which is usually applicable to the case of full yarn balls. It reflects the influence of the actual yarn binding length on the tension and ensures that the appropriate tension is maintained during the yarn binding process. Example

[0036] Taking the production of GYTS-288 core optical cable as an example, the specific tension control parameters are set as follows: The production speed C is set to 30 m / min, which is suitable for the production of GYTS-288 optical cable; Set the tension correction coefficient A to about 2.5 to meet the specific tension requirements of GYTS-288 core optical cable during the production process, and to fine-tune the tension setting value B; The tension setting value B is 240 to ensure that when producing GYTS-288 core optical cable, the cable will not be damaged due to excessive tension, nor will the cable shape be unstable due to too little tension; The tension speed coefficient D is set to 0.5-1.5, which is used to fine-tune the tension according to the production speed C to maintain tension stability and consistency during low-speed production. It is suitable for the production of GYTS-288 optical cable; The yarn binding length coefficient E is set to 1.1, which is usually applicable to the case of full yarn balls. It reflects the influence of the actual yarn binding length on the tension and ensures that the appropriate tension is maintained during the yarn binding process.

[0037] The beneficial effects of the cable cabling machine yarn tension control method of the present invention are: The program control is simple and easy to operate and debug. The operator only needs to make a small correction to the key parameters to achieve precise control of the yarn tension, which simplifies the operation process, reduces the complexity of operation, and is suitable for all types of optical cables; The equipment debugging time is greatly shortened, and technicians can quickly complete the tension control settings for the speed increase and decrease stages, the low-speed start-up stage, and the high-speed operation stage, which improves the debugging efficiency and thus improves the overall production efficiency; Precise tension control reduces cable damage or defective products caused by improper tension, helping to ensure consistency and stability of product quality.
