ABSTRACT:
The mechanism accurately removes rounds of ammunition from a moving horizontal conveyor and places them into a stationary partitioned tray which is disposed below both the inventive mechanism and the conveyor. The mechanism comprises two counter-rotating dump bars driven by an indexing drive assembly which, in turn, comprises a combination of geneva-type indexing drive units and conventional gearing. The indexing drive assembly provides the dump bars with a 16-to-1 dwell-to-drive ratio, and rotates the bars 90.degree. each actuation. The dump bars have guiding surfaces across which the rounds of ammunition are moved by elements of the horizontal conveyor, while the dump bars are in the locked dwell position. When the dump bars are full of rounds, the bars index and transfer the rounds out of the conveyor elements and into the tray for subsequent operations, without interaction with, or interference by, the conveyor. Adjacent rounds that follow the original rounds then begin to fill the bars, and the operation is repeated in a cyclic manner.
