Abstract: A loading machine for cartridges with metal cases receives the empty cases provided with primer, prepares them and provides them with the components to produce the cartridges. The loading machine includes first and second operating beams, each having alternating vertical translation movement coordinated with one another; a continuously rotating motor activating kinematic mechanisms; a gearbox transmitting motion from the motor to the first and the second operating beam. The gearbox includes: a drive shaft; at least a first and the second connecting rod and crank kinematic mechanism connected to the first operating beam and the drive shaft respectively by a first and second cams; third and fourth connecting rod and crank kinematic mechanisms connected to the second operating beam and to the drive shaft respectively by third and fourth cams. The alternating vertical translation movement of the first beam is independent from the alternating movement of the second beam.

Abstract: Disclosed is a loading machine for cartridges with a metal case including a frame structure; a feed unit for a plurality of cases having a longitudinally extending axis; a first operating beam having an alternating vertical translation movement, provided with working tools having a vertical axis, adapted to load the cases; feed and a conveyor of the cases and element for ejecting the loaded cartridges; a motor and a control unit. The feed unit includes a race and a conveyor guide comb defining a plurality of seats, containing the cases conveying them along the race. The conveyor guide includes bushings, each including at least a first conical surface and a hole to house one of the bushings and being housed in one of the seats. The machine includes a second operating beam, having an alternating vertical translation movement, provided with a plurality of hollow centering cylinders having a vertical axis.
