Title:
METHOD AND APPARATUS FOR CONTROLLING PRODUCTION AND QUALITY OF PRODUCTION UNIT IN MULTIPLE WEIGHT TYPE FIBER MACHINE
Document Type and Number:
Japanese Patent JPS63256732
Kind Code:
A
Abstract:
A common monitoring system with a light beam is provided for a group of two or more production units arranged in a row. The beam passes through the thread balloon formed by the moving thread of each of these production units and is intermittently interrupted or attenuated by the moving thread in each balloon. The resulting shading is converted into an electric signal in a receiver of the monitoring system. The threads of the individual production units can be identified by evaluating the relationships of amplitude, time and phase between the individual shading impulses. The process enables on-line production and quality control to be carried out on multi-spindle textile machines such as ring spinning machines at an acceptable cost.
