Innovation and development of intelligent spinning solutions

Milestone project （Jingwei Textile Machinery Co.， Ltd. under the command of CHTC）

In September 2014， Ningxia Ruyi Project realized the large-scale application of the linkage system of roving， spinning and winding for the first time， laying a foundation for the promotion of the linkage.

In October 2015， Jiangsu Dasheng Project realized the establishment and operation of the first digital spinning workshop in China， and successfully passed the acceptance of the national digital spinning project， promoting the promotion and development of digital spinning equipment.

In June 2016， the entire process of the XinjiangTexhong project was fully upgraded in terms of automation， production efficiency， equipment stability and other equipment performance， with a total scale of 450，000 spindles.

In June 2017， Nanyang Textile Project realized the application of the largest single-unit workshop of domestic linkage system of roving， spinning and winding for the first time. The total scale of the project was 200，000 spindles.

In October 2019， the project of Wuhan Yudahua full-process intelligent spinning realized the whole process of intelligent logistics， the whole process of reworkable waste collection， and the whole process quality traceability， laying the foundation for the unattended factory at night.

The features of intelligent spinning solutions

The whole process intelligent spinning solution includes the production pro- cess from raw material to the yarn， from the control of the workshop environment auxiliary equipment to the performance and maintenance of the host equipment； from the workshop material management， production management， equipment management， technology Management， digital and intelligent. From the quantitative combination of stereotypes to digital analysis. The control methods that rely on human tactics and uninterrupted roving can be maintained and guaranteed， and become standardized， systematic and digital work guarantee measures， reducing the fluctuations and instability caused by human factors， and the information that is hard for people to discover and provide is summarized and predicted through machine selflearning functions to achieve control. The visual observation system automatically recognizes and guides the accurate delivery and packaging of materials. Using digitalization， information technology instead of labor， beyond the manual， to achieve intelligence.

Yudahua project application case analysis

The intelligent spinning management system forms an intelligent analysis based on the real-time status of production operation and product quality， and a new collaborative manufacturing system based on logistics， dispatching and automatic cotton mixing. Through the automated collection of large amounts of data and traceability of production information， the control of information flow and logistics coordination has reached the intelligent spinning workshop with precision， and created a collaborative innovation and innovation control platform for intelligent manufacturing.

The module mainly includes： order management， spinning process design， online quality control， test data management analysis， production statistics analysis， output salary management， electric power management， production rate analysis， first-line employee APP， and component lifecycle management modules， etc..

Intelligent scheduling

Smart scheduling of orders - Realizing the automatic scheduling of orders in the whole process， and produce plans of various productions， making the plan more scientific， more efficient and more reasonable.

Intelligent scheduling - AGV-E System-WCS System Intelligent Scheduling： Intelligent Scheduling of AGV Handling between Carding Bars and Pre-Track Systems.

After the roving， the canister is intelligently prepared - Realizing the preparation of the finishing drum according to the production condition of the roving， so that the production between the processes is smoother.

The linkage of roving and spinning intelligent preparation - According to the actual production situation of the spinning frame， the roving full yarn library is arranged intelligently， which makes the production of the linkage smoother.

Cotton mixing - process - quality management

Process management： It is mainly divided into two parts. The first part is mainly to realize the informationization of the spinning process. Through reasonable demand analysis， the process parameter data dictionary of each model is formed， and the user can increase or delete the process parameters according to actual needs. Then， the finished product is the main line， and the process data of each process is connected to the system. The second part of the management system is to realize the functionalization of process management， and develop basic functions such as copying， editing， detailing， exporting， and deleting. Since there are some varieties or similar varieties that have been spun in the workshop， when the process parameters of the process change little， the function of the process single copy can be used， and then some parameters can be modified by editing.

Workshop logistics visualization

It can realize the production schedule of equipment， fault， real-time working conditions， dynamic handling process of AGV trolley， real-time dynamic handling process of rail system， display of semi-product quantity between processes， dynamic process of the linkage of roving and spinning and full yarn library.

Full process quality traceability

The quality traceability system records the actual data provided by the workshop automation logistics system， and records it in each production process of the spinning machine. For each finished product （bins， roving tube， spinning tube）， its production information is recorded： Including the machine number （ingot number） of the equipment produced， production time， vehicle handlers， production process， etc. Recorded into the database， these virtual data is synchronized with the product（semi-product）.

When it is necessary to trace back， it can be traced back through the flow data record to find out its production information， as well as the production information of the previous process， and provide data support for process optimization， single spindle maintenance of the spinning frame， and other management.

The quality traceability page is to show all the varieties and pre-spinning processes in the current workshop. When you select a certain variety， you can display the varieties of the pre-spinning processes corresponding to the variety， and realize the data from the single-spindle → spinning spindle → roving spindle → end machine side → front spinning production line →cotton mixing → raw cotton quality and process traceability.

Future development prospects

At the textile machinery technology upgrade seminar held in Wuxi in 2017， the technical upgrading route and development direction of the future spinning factory were basically verified in the Yudahua project. The next step is to optimize the overall system， improve operational efficiency， reduce investment and operating costs， improve the overall planning of project implementation， and form a complete intelligent spinning solution from the perspective of system engineering. Intelligent spinning equipment will soon be promoted to more Implemented and applied in many factories.

Realizing the visualization of the production process can improve the effect of man-machine cooperation and improve the use experience； digitally simulate the production process， which can reduce the product development cycle and improve the market reaction speed； realize the spinning through big data operation through the self-learning function of the machine equipment Process optimization and upgrading， etc..

The future spinning smart factory will not only remain in the imagination， but the application of intelligent equipment and systems will gradually complete the complete puzzle of the spinning smart factory. China Hi-tech Group Corporation will work together with textile enterprises to grow together and provide intelligent equipment support and services for the technological upgrading of textile enterprises.
