A conveyor system includes at least one conveyor table and an awareness flag mechanism. The awareness flag mechanism includes a support rod mounted to the at least one conveyor table and extending outwardly therefrom in a cross-conveying direction. A counterweight assembly includes a support shaft pivotally connected to the support rod. The support shaft has a resiliently flexible portion. Aa counterweight is located at a lower end of the support shaft. Aa flag is located at an opposite, upper end of the support shaft. The counterweight biases the counterweight assembly toward an upright, awareness configuration where the flag is located above a conveying surface of the at least one conveyor table.
