Title:
SINGLE SPINDLE ON-LINE DETECTION SYSTEM FOR SPINNING FRAME
Document Type and Number:
WIPO Patent Application WO/2021/128625
Kind Code:
A1
Abstract:
A single spindle on-line detection system for a spinning frame, the system comprising a main control panel for single spindle detection, spindle speed acquisition panels and a control panel for stopping roving feeding; the spindle speed acquisition panels are connected to the main control panel for single spindle detection by means of a CAN bus, and each spindle speed acquisition panel is mounted on the CAN bus, or two or more spindle speed acquisition panels are connected in series before being mounted on the CAN bus; the spindle speed acquisition panels are each used to acquire the rotational speed of a spindle as well as the status of yarn and use the CAN bus to send to the main control panel for single spindle detection a data message that contains the rotational speed of the spindle and the status of the spindle; the main control panel for single spindle detection is used to identify the spindle speed acquisition panel that sends the data message when two or more spindle speed acquisition panels are connected in series before being mounted on the CAN bus and send to the control panel for stopping roving feeding an instruction to stop roving feeding when the yarn has broken ends so as to stop the feeding of roving. The described single spindle on-line detection system for a spinning frame features good adaptability to work conditions.
