Roller Conveyor and Method for Detecting Synchronization of Rollers

摘要

The present invention provides a roller conveyor device used for transferring glass substrates. The device includes a plurality of transaxles arranged in parallel to each other and located coplanarly are incorporated with at least a pair of rollers and each of the rollers is labeled with a mark on its side. The present invention further provides a method for detecting synchronization of rotating rollers. By way of detecting the synchronization or the side marks, each of the rollers can be determined whether it is synchronized with others so as to avoid any detrimental consequences, i.e. breakage or cuts resulted from the asynchronization.
