Description

Technical Field

[0001] The invention relates to a spinning production statistics system and method based on spinning speed, belonging to the technical field of textile production statistics. Background Art

[0002] The production process of chemical fiber filaments is basically that the raw materials are heated by a screw extruder and the extrusion pressure is controlled to become a hot melt. The hot melt is measured by a high-precision metering pump and then spun. The spinning is cooled by side blowing and then wound up by a winder at high speed. At present, some chemical fiber filament spinning machines in use in China are relatively old, and the equipment monitoring system has no production statistics or the production statistics are inaccurate. During the process of information upgrading and transformation, it is impossible to accurately obtain production statistics data, and statistics need to be based on data collected on site. Summary of the invention

[0003] In view of the above-mentioned defects in the prior art, the present invention proposes a spinning production statistics system and method based on spinning speed, which can realize accurate statistics of spinning production data.

[0004] The spinning production statistics system based on spinning speed includes spinning production equipment, which includes a screw extruder, a melt pipeline, a metering pump, a spinning box, a spinning assembly, a side-blowing mechanism and a winder. The spinning raw material is heated by the screw extruder and the extrusion pressure is controlled to become a hot melt. The hot melt is connected to the spinning assembly of the spinning box after being metered by a high-precision metering pump through the melt pipeline. The spinning assembly is connected to the winder after being cooled by the side-blowing mechanism. The present invention also includes statistical equipment, which includes a data collector, a data server, a display and a client; the data collector is respectively connected to a pressure sensor, a winding machine speed sensor, and a metering pump frequency converter; the data collector transmits the collected information to the data server through a data line and displays it through a display; the data server is connected to the client through a data line.

[0005] Preferably, the spinning production equipment also includes a monitoring system, and the data collector is connected to the pressure sensor, the winding machine speed sensor, and the metering pump frequency converter through the monitoring system; wherein the pressure sensor is connected to the screw extruder and the melt pipeline, the speed sensor is connected to the winding machine, and the metering pump frequency converter is connected to the metering pump.

[0006] Preferably, the information collected by the data collector includes: pressure information of the screw extruder and the melt pipeline, motor speed information of the metering pump, and spinning speed information of the winding machine.

[0007] Preferably, the data server receives the data collected by the data collector to display and count the production information of the spinning production equipment on the production line.

[0008] Preferably, the client includes a PC, a mobile phone, or a tablet computer, and the client receives information processed and published by the data server.

[0009] The spinning production statistics method based on spinning speed of the present invention comprises a spinning production device and a statistics device. The statistics device judges the spinning production action according to the real-time spinning speed, the set spinning speed, the set spinning time, the melt pressure and the speed of the metering pump, and divides the spinning production action into: the starting stage, the spinning stage, the production stage, the doffing stage, the switching stage, the breaking and the end of spinning;

[0010] When the melt pressure and metering pump speed are greater than 0, it means that the sliced ​​raw materials in the spinning machine are melted and enter the spinning box for production. The statistical methods for each stage are as follows:

[0011] Start-up stage: the spinning speed increases from 0 to 1.01-1.02 times of the set speed;

[0012] Spinning stage: if the spinning speed drops from 1.01-1.02 times of the set speed to the set speed and is maintained for more than 5 minutes, it means that the spinning is successful. If the spinning speed drops to 0, it means that the spinning fails.

[0013] Production stage: The spinning speed is maintained at the set speed, and the deviation is kept within the set deviation value, indicating normal spinning production;

[0014] Fiber drop stage: When the spinning time reaches the set spinning time and the spinning speed increases to 1.01-1.02 times the set speed, it means that the fiber drop is completed. When the spinning time reaches and exceeds the set spinning time and the spinning speed does not increase to 1.01-1.02 times the set speed, it means that the fiber drop is completed.

[0015] Switching stage: after doffing, the spinning speed is maintained at 1.01-1.02 times the set speed for 5-30 seconds. If the spinning speed drops to the set speed and is maintained for 5-10 minutes, it indicates that the switching is successful. If the spinning speed drops to 0 or keeps the set speed for a short time, it indicates that the head switching has failed. When the collected spinning time exceeds the set spinning time, and the collected spinning speed does not increase to 1.01-1.02 times the set speed and then decrease to the set speed, it also indicates that the switching has been successful.

[0016] End breakage: The spinning time does not reach the set time, and the spinning speed drops to 0;

[0017] End of spinning: When the spinning time reaches the set time, the spinning speed drops to 0, and the melt pressure drops to 0, the spinning production ends.

[0018] The time from successful spinning to yarn drop or yarn breakage is the production time of the spun product, which is calculated by the following formula:

[0019] Yarn roll weight = adjustment coefficient * metering pump speed * pump supply * number of yarns * spinning production time

[0020] The weight of the yarn roll product is calculated, and the spinning time or the yarn roll weight is used to determine whether the spun product is a full roll, a small roll, a defective product, or waste yarn, and the spinning time and the number of the products are counted. The production time when the melt pressure and the metering pump speed are greater than 0 is counted to obtain the total output, and then the full roll rate and waste yarn rate data are calculated.

[0021] The beneficial effects of the present invention are: the spinning production statistics system and method based on spinning speed described in the present invention realize spinning production statistics through key parameters such as spinning speed, and the accuracy of statistical data reaches more than 99%, which can be used in production informatization to replace manual statistical records.

[0038] Embodiment 2:

[0039] like Figure 3 As shown, the statistical analysis method of the present invention is based on the principle of collecting as little data as possible. The on-site equipment collects the main parameters: real-time spinning speed, set spinning speed, set spinning time, melt pressure and metering pump 3 speed. The real-time spinning speed is used to judge the spinning production actions, such as starting, spinning, production, doffing, switching, and breaking. The specific judgment method is as follows:

[0040] When the melt pressure and the speed of the metering pump 3 are greater than 0, it means that the sliced ​​raw materials are melted in the spinning machine and enter the spinning box 4 for production. The specific judgment conditions for each production stage are as follows:

[0041] Start-up stage: The spinning speed increases from 0 to 1.01-1.02 times of the set speed. Figure 4 middle time periods t1-t2, t9-t10 and t13-t14;

[0042] Spinning stage: The spinning speed drops from 1.01-1.02 times the set speed to the set speed and is maintained for a certain period of time, generally more than 5 minutes, indicating that the spinning is successful. Figure 4 In the middle time period t2-t3 and t14-t15, if the spinning speed drops to 0, it means that the spinning has failed. Figure 4 Middle time period t10-t11;

[0043] Production stage: The spinning speed is maintained at the set speed, and the deviation is kept within the set deviation value, indicating normal spinning production. Figure 4 Time periods t3-t4, t6-t7 and t15-t17;

[0044] Fiber drop stage: When the spinning time reaches the set spinning time and the spinning speed increases to 1.01-1.02 times the set speed, the fiber drop is completed. Figure 4 In the time period t4-t5, when the spinning time reaches and exceeds the spinning setting time, the spinning speed does not increase to 1.01-1.02 times the setting speed. This situation is considered to be complete. Figure 4 If the time period t15-t16 exceeds the spinning setting time, it is considered that the spinning setting time has been exceeded and the doffing is completed;

[0045] Switching stage: After the spinning is dropped, the spinning speed is maintained at 1.01-1.02 times the set speed for a certain period of time, generally 5-30 seconds. If the spinning speed drops to the set speed and is maintained for a certain period of time, generally 5-10 minutes, it means that the switching is successful. Figure 4 In the time period t5-t6, if the spinning speed drops to 0 or keeps the set speed for a short time and drops to 0, it means that the spinning switch fails; when the collected spinning time exceeds the set spinning time, and the collected spinning speed does not increase to 1.01-1.02 times the set speed and then decreases to the set speed, this situation is also considered to have been switched successfully, such as Figure 4 If the time period t15-t16 exceeds the spinning setting time, it is considered that the switching is successful if the spinning setting time is exceeded;

[0046] End breakage: The spinning time does not reach the set time, and the spinning speed drops to 0. Figure 4 Time points t7 and t11.

[0047] The time from successful spinning to silk drop is the spinning production time. The weight of the silk roll product can be obtained by the calculation formula (silk roll weight = adjustment coefficient * metering pump speed * pump supply * number of heads * spinning production time). The spinning time or silk roll weight can be used to determine whether the spinning product is a full roll, small roll, waste, waste silk, etc., and count them.

[0048] By counting the production time when the melt pressure and metering pump speed are greater than 0, the total output can be obtained, and further production statistics such as full roll rate and waste wire rate can be calculated.

[0049] The method of the invention realizes spinning production statistics by utilizing key parameters such as spinning speed, and the accuracy of statistical data reaches more than 99%, and can be applied to production informatization to replace manual statistical records.

[0050] The invention can be widely used in textile production statistics.
