Abstract
A transfer conveyor for transporting an object from an intake location to an output location according to the invention has a frame adjacent the locations, a planet carrier rotatable on the frame about a carrier axis, a wheel rotatable on the frame adjacent the carrier about the carrier axis, and at least one planet gear carried on the carrier and rotatable thereon about a planet axis parallel to but offset from the carrier axis. A ring gear meshing with the planet gear is centered on but not rotatable relative to the carrier axis. The gears have respective pitch circles and the circumference of the ring-gear pitch circle is a whole-number multiple of the circumference of the planet-gear pitch circle. A support carried on the wheel is coupled to the planet gear offset from the planet axis so that the support orbits about the planet axis as the planet gear rotates. A suction gripper mounted on the support moves jointly therewith at least radial of the carrier axis. A drive rotates the planet carrier about its axis and thereby displaces the suction gripper past the locations in a hypocycloid having cusps at the locations.
