CONTROL TO OPTIMIZE ORDER OF JOINT CONVEYOR TO APPROACH TO MACHINE IN SPINNING PROCESS

PURPOSE: To provide a controlling method to determine the optimum order of a joint conveyor for approaching to each spinning machine based on a state of the bobbin of the spinning machine before full package and a moving distance from the present position of the joint conveyor to the spinning machine. CONSTITUTION: In a spinning process where a great number of spinning machines 1 are operated, automatic doffing is performed on a full-package spinning machine while plural automatic doffing machines 2 move and approach to spinning machines 1. Subsequently, the joint conveyor 3 approaches to the spinning machine 1 whose bobbin has been picked up and a bobbin is exchanged in the spinning machine 1. In this spinning process, the order for approaching to the machine is optimized.
