Abstract
The present invention relates to a loom control system operable to stop a loom in the presence of a yarn breakage. This loom comprises a feeding device having a yarn storage drum for temporarily storing the yarn and a yarn store sensor for sensing the quantity of yarn stored on the drum of the feeding device and for transmitting an electric sensor signal representing the quantity of yarn stored on the drum to the feeding device to control the operation of the feeding device and to thereby control the quantity of yarn stored on the drum. A monitor circuit is electrically connected to the yarn store sensor for receiving the sensor signal, wherein the monitor circuit derives information on yarn breakage before and/or after the feeding device from the sensor signal or its variation with respect to time to generate a stop signal for the loom.
Claims6
A loom control system operable to stop a loom in the presence of a yarn breakage, said loom including a feeding device having a yarn storage drum for temporarily storing the yarn, and yarn store sensor means for sensing the quantity of yarn stored on said drum of said feeding device and for transmitting an electric sensor signal representing the quantity of yarn stored on said drum to said feeding device to control the operation of said feeding device and to thereby control the quantity of yarn stored on said drum, said loom control system including monitor means for detecting a yarn breakage and for stopping the loom in the event of a yarn breakage, wherein the improvement comprises said monitor means being electrically connected to said yarn store sensor means for receiving said sensor signal therefrom, and said monitor means being responsive to said sensor signal representing the quantity of yarn stored on said drum for detecting a yarn breakage and said monitor means generating a stop signal for the loom in response to detection of a yarn breakage.
