ABSTRACT
Ring data system consists of a traveling sensor, known as traveler, runs continuously back and forth at the height of the ring rail on each side of the machine on a single machine (pilot unit) or on all machines in the mill. This generates a magnetic field that is affected by the rapidly rotating traveler. If a yarn break occurs, the traveler ceases to rotate and the sensor displays the resulting impulse as an end down, also recording the number of the spindle. As a result of its rapid motion back and forth it registers the spindle several times until the end down is repaired. Thus precise recording of spindle downtime becomes possible. Another sensor fitted on the front roller records the delivery speed and machine stoppages, thus gives exact record of production rate and loss of fibers in Bonda waste as per the count running on ring frame. One more sensor keeps the track for the number of doffs and their duration. All the information collected is ultimately transmitted to a computer with monitor and printer, which performs the necessary analysis and stores the data for preset periods. The following data are available via reports on individual machines, individual blends or the installation as a whole that are printed out or can be called up on the monitor any time:
• Machine number
• Date
• Time
• Period monitored
• Production period
• Spindle speeds
• Yarn twist
• Output in kg
• Output in g/spindle /hr.
