How RFID is Used in the Roving Bobbin Transport System

Over the past few years of textile development, roving frames have transitioned from traditional iron cannon speed adjustments to being dominated by computerized roving frames. With the rise of computerized roving frames, labor shortages and high labor costs have driven the rapid evolution of the roving bobbin transport system, providing equipment assurance for automated and continuous production in textile factories. However, the characteristics of multiple machines, different machine types, spinning differences, and product diversity between roving and fine spinning in spinning factories not only pose significant challenges to production management but also limit the improvement of production efficiency. Especially under the market pressure of multiple types, small batches, and short cycles, ensuring that the roving bobbin transport system meets the requirements of multiple varieties and small batches, preventing confusion in the spun varieties, ensuring traceability, enhancing intelligent management, and optimizing production in spinning factories are crucial. By leveraging the features of the roving bobbin transport system and employing RFID radio frequency identification technology, it’s possible to identify, track, and remotely monitor the transportation process, automatically optimize the demand allocation of each machine, automatically record and timely feedback monitoring information, and achieve the transmission and control of logistics and information flow between roving and fine spinning machines. This not only saves labor and improves efficiency but also provides strong support for managers to adjust production arrangements and achieve flexible production scheduling in real-time.

Roving Bobbin Transport System Control Solution Based on RFID Technology

The roving bobbin transport system is a process of exchanging logistics and information flow between roving and fine spinning machines. This process is not just a simple transportation process of full and empty tubes, but also requires reasonable transportation scheduling and variety scheduling based on roving storage time, roving variety, and real-time demand of fine spinning machines. Traditional roving bobbin transport products only solve the logistics transportation process, but variety identification and reasonable production arrangements require manual participation, which cannot achieve real-time tracking, precise management, and intelligent control of the production process. In response to the actual production needs of textile factories, the roving bobbin transport control system adopts advanced RFID technology, combined with computer communication technology and field bus control technology, with RFID and sensor networks at its core, to achieve real-time tracking and remote monitoring of every part of the transportation process, automatically optimize roving demand; achieve the first-in-first-out of full yarn in the yarn warehouse, the shortest storage time of roving in the yarn warehouse; achieve automatic yarn variety identification and automatic confirmation; meet the small batch and multi-variety needs of spinning factories, and ensure the correctness of yarn varieties. 

Roving Bobbin conveyor System Control

From above image it can be seen that the entire control system consists of the CC-LINK field bus network, RFID radio frequency identification network, and the main control center. The CC-LINK field bus mainly completes the entire action process of the roving bobbin transport system; RFID radio frequency identification mainly completes the information identification of roving and empty tubes and sends the identification information to the main control center for processing; the main control center, as the core of the entire control system, is responsible for the collection, analysis, and processing of information, issuing control commands, and completing the orderly, reliable, and efficient operation of the entire roving bobbin transport system through the CC-LINK bus. Because the number of roving and fine spinning machines in each factory’s roving bobbin transport system is different, and the equipment installation positions are different, the control system is divided into modular control, divided into roving machine control module, intelligent yarn warehouse control module, public transportation control module, and fine spinning machine control module. Each part serves as a control module, corresponding to a control program, and all program scheduling is coordinated by the main control center. The transportation of roving and empty tubes is achieved through the transportation chain, so in the implementation plan, each transportation chain is equipped with an electronic tag, and the electronic tag is given a different ID as the unique identification of each transportation chain. At the mechanical hand of the roving machine for changing yarn, the entrance and exit of the intelligent yarn warehouse, and the entrance and exit of each fine spinning machine, a card reader is installed to identify and collect information on the full and empty tubes of the entire roving bobbin transport system.
