A machine for automatically positioning objects, comprising: - at least one inlet conveyor configured to transport a plurality of objects in a lying position; - a transfer conveyor with a plurality of transfer fasteners attached thereto, the transfer fasteners being movable along a closed loop in a plane tilted with respect to the horizontal, between an upper receiving region, where the transfer fasteners are movable in a first direction and configured to receive the objects held in a lying position, and a lower delivery region, where the transfer fasteners are movable in a second direction opposed to the first direction and configured to deliver the objects held in an upright position, transferring the objects from the lying position to the upright position due to the movement of the transfer fasteners along the close loop; - at least one outlet conveyor adjacent to the lower delivery region of the transfer conveyor and synchronized thereto for receiving the objects in the upright position; - a detector system configured to identify at least an orientation and/or a shape of the objects transported on the inlet conveyor; - at least one robotic collection device configured to collect the objects in the lying position from the inlet conveyor, to rotate along a vertical axis according to the information received from the detector system and to transfer the object to the upper receiving region of the transfer fasteners moving the object in the first direction in coordination with the movement of the transfer fasteners; the transfer fasteners are attached in fixed positions along a periphery of a transfer conveyor movable along the closed loop, the transfer fasteners being dragged by the transfer conveyor; each transfer fastener includes a suction nozzle, connected to a suction source, each suction nozzle defining a seat surface tilted with respect to the tilted plane of the closed loop and which is approximately horizontal when in the upper receiving region and which is approximately vertical when in the lower delivery region; and wherein the seat surfaces of all the transfer fasteners are exposed non-recessed surfaces, which are not contained within a housing or depression, at its bottom, but accessible exposed surfaces on top of which objects of any shape or size can be placed without requiring adaptation of the transfer fastener due to the lack of housing or depression adapted to contain said object, the seat surfaces being configured to retain the objects by suction, without confinement of the objects in the transfer fasteners. - at least one inlet conveyor configured to transport a plurality of objects in a lying position;
