ABSTRACT:
A transport system for articles includes an upper conveyor and a lower conveyor, and an elevator having an elevator conveyor and movable in a vertical direction between a lower end position in which the elevator conveyor is in alignment with the lower conveyor, and an upper end position in which the elevator conveyor is in alignment with the upper conveyor. The transfer of the articles between the conveyors and the elevator conveyor is controlled by a control unit which cooperates with a signaling assembly including a first signaling member associated to one plane for indicating that the elevator has reached an upper trigger position during movement from the lower end position to the upper end position, and a second signaling member associated to the other plane for indicating that the elevator has reached a lower trigger position during movement from the upper end position to the lower end position.
