Abstract

Method of monitoring the production process of automatic winding machines includes forming and indicating, in predetermined time intervals, a handicap net efficiency from action of at least one of the winding stations of the winding machine, and an actual net efficiency actually resulting from running and shutdown of the winding machine, and system for carrying out the foregoing method.

Claims

1. Method of monitoring the production process of an automatic winding machine which comprises feeding to a data processing installation, measuring pulses corresponding to the times a knotting device is operated within a predetermined time interval, converting the pulses to a total operating time value, feeding to the data processing installation a time value corresponding to an average down time value for servicing the winding station so as to eliminate shutdowns thereof, and determining from the time values in the data processing installation average down time values for average servicing and forming a ratio of the average down time values to the total operating time values of the machine that is the handicap net efficiency to form the handicap net efficiency.

2. System for carrying out a method of monitoring the production process of an automatic winding machine, comprising knotter monitoring means, a pulse transmitter operatively connected to said knotter monitoring means for transmitting at least one measuring pulse for each operation of the knotter, a data processing installation having a converter connected to said pulse transmitter and adapted to convert said measuring pulses therefrom to total operating time values, means for feeding given down time values for servicing the winding machine to said data processing installation, said data processing installation including a device for determining from the time values fed to said data processing installation average down time values for average servicing and forming a ratio of the average down time values to the total operating time values of the machine that is the handicap net efficiency, and means for showing the handicap net efficiency.

3. System for carrying out a method of monitoring the production process of an automatic winding machine, comprising means for transmitting commands to a knotter, a knotter monitoring means, a pulse transmitter operatively connected to said knotter monitoring means for transmitting at least one measuring pulse for each operation of the knotter, a data processing instalLation having a converter connected to said pulse transmitter and adapted to convert said measuring pulses therefrom to total operating time values, means for feeding given down time values for servicing the winding machine to said data processing installation, said data processing installation including a device for determining from the time values fed to said data processing installation average down time values for average servicing and forming a ratio of the average down time values to the total operating time values of the machine that is the handicap net efficiency, and means for showing the handicap net efficiency.

4. Method of monitoring the production process of an automatic winding machine comprising the step of measuring at predetermined time intervals the down time and total operating time of said machine, determining from said down time and said total operating time the actual net efficiency, measuring during said predetermined time intervals the average down time for average servicing resulting from actual past experience and the total operating time of said machine, determining from said average down time and said total operating time a handicap net efficiency, and comparing in said predetermined time interval the actual net efficiency to the handicap net efficiency.
