The machine has a gripper (8) supported on a base plate, and rotatably driven around an axle (9) in a rotating direction (45) by a gripper drive shaft (10). A capsule lifter (33) comprises a lifter arm (32) installed opposite to lifter cams (31), and a push button (36) loaded by a spring (37). The push button is installed on a rotatably driven radial cam (40), which is directly arranged at a lower side (38) of the gripper and opposite to the gripper in a non-rotatable manner. The radial cam comprises a thickness in a direction of the axle of the gripper drive shaft.
