RINGDATA by Zellweger

Index

A traveling sensor 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. The spindle downtime is therefore also recorded. Another sensor fitted on the front roller records the delivery speed and machine stoppages, and another 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:

  • machine number
  • date
  • time
  • period monitored
  • production period
  • spindle speeds
  • yarn twist
  • output in kg
  • output in g/spi.h
  • efficiency
  • downtimes
  • doffing times
  • number of cops doffed
  • number of ends down
  • ends down per 1 000 spindle hours
  • mean duration of ends down
  • preset maximum number of ends down
  • number of spindles with ends down exceeding this limit.
