  • Method and apparatus for volume or size detection of a yarn package and for deriving confined control processes therefrom
    Patent number: 5142159
    Abstract: The method and apparatus optically scan the size of a yarn package of a spinning bobbin with a plurality of light transmitters and light receivers and derive defined control processes in accordance with the ascertained size. Bobbins with yarn packages are moved in a given direction of motion at a predetermined speed between a plurality of paired and mutually opposite light transmitters and light receivers disposed one above the other with respect to the given direction of motion for placing at least some of the light receivers into a shadow. At least one of the light transmitters and light receivers are switched on and off in cycles at a predetermined rhythm, order and duration. A signal is delivered to a computer from each of the light receivers placed into a shadow in each cycle by the bobbin. The volume of the applicable bobbin is calculated with the computer from a given time required for scanning one bobbin and from the signals from the shadowed light receivers delivered during the given time.
