Abstract
A conveying system for crowns used to cap containers having a portion thereof adapted to detect and eject bent crowns comprising a conveyor chute for permitting the gravity feed of bent and unbent crowns therethrough, a conventional crown orienting apparatus for orienting each crown to be in the same relationship and a transfer system between the conveyor chute and the crown orienting apparatus for transferring crowns between the conveyor chute and the crown orienting apparatus and wherein the transfer system has a movable bent crown detecting apparatus for stopping the movement of bent crowns therethrough but permitting the movement of unbent crowns therethrough. A sensing device that is responsive to the stoppage of flow of the crowns through the bent crown detecting apparatus is provided and functions to signal appropriate apparatus to stop the flow of crowns into the transfer system, to move the detecting apparatus so that the bent crown may move therethrough and to activate a bent crown ejecting apparatus to remove the bent crown from the transfer system and to return the conveying system to normal operations.
