Abstract:
A system and method for selectively transferring storable units (10), particularly artillery propellant charge units, between a storage space (18) and a location outside of the storage space, the system including a storage magazine (12) having a plurality of parallel, axially elongated chambers (20) opening at an end of the storage magazine, a shuttle (14) having a transfer mechanism tube (50) movable relative to the storage magazine between positions of axial alignment with each of the plurality of elongated chambers and the location outside of the storage space, and a feed mechanism to move the units between the transfer tube (50) and the elongated chambers (20). Where the elongated chambers (20) are respectively centered on Z axes with open ends (18) presented at intersecting X and Y axes perpendicular to the Z axes, the shuttle (14) is translatable in an X direction and supports the transfer tube (50) on a Z-axis for movement in a Y direction relative to the storage magazine so that a combination of shuttle translation on the X axis and movement of the transfer tube on the Y axis positions the transfer tube in axial alignment with the respective open ends of each of the plurality of cylindrical tubes. The feed mechanism moves the charge units in the Z direction between the respective elongated chambers (20) and the transfer tube (50). A conveyor aligned with a Z axis delivers charge units to and from the storage magazine and is positioned for transfer of charge units to and from the shuttle mounted transfer tube (50).
