ABSTRACT:
An apparatus for aligning nuclear fuel pellets includes an endless belt for advancing nuclear fuel pellets along a generally linear path in a direction generally coincident with their axes and a stopper element disposed in the linear path for stopping advancement of the pellets therealong for assembling pellets in a row. A detector device senses when advancement of a prescribed number of the pellets in a row have been stopped by the stopper element. A feed mechanism is operable for successively feeding pellet holding trays one at a time to a pellet receiving position along the linear path. A panel defines an inclined path extending from the linear path downward to the one tray disposed at the receiving position. An ejector mechanism disposed along the linear path is responsive to the detector device for pushing the assembled row of pellets sidewise from the linear path along the inclined path of the panel to a groove defined in the one tray. A guide mechanism provided adjacent the linear path is operable for guiding the row of pellets down the inclined path to the tray. A pellet grasping mechanism is disposed along the linear path for blocking advancement of more pellets along the linear path once the detector device has sensed when advancement of the pellets has been stopped by the stopper element.
