Yarn Feeder Stack Position Learning via Secondary Optical Channel

The yarn feeders automatically perform the identification code assignment themselves through mutual communication via the BUS. Each feeder determines its own position in the stack by receiving signals from feeders above it and transmitting signals to feeders below it, eliminating the need for manual operator intervention and ensuring accurate, error-free numbering.

The identification code assignment is performed automatically during the initial stacking configuration before production begins. The feeders establish their identification codes and positional relationships in advance through self-communication, so that when production starts, the central control unit already has accurate information about each feeder's position without requiring any manual setup time.

The error management communication is segmented into two paths: routine error status data is handled locally between adjacent feeders through direct BUS communication, while only critical error information requiring central intervention is transmitted to the main control unit. This segmentation reduces the overall data flow burden on the central BUS during weaving operations.

Adjacent yarn feeders act as intermediaries for error management communication. When an error occurs, the affected feeder communicates with its neighbors through the BUS, allowing local error handling and coordination without requiring all data to traverse the entire central communication network, thereby reducing data transmission load.
