Claim:
A transport system for articles, in particular containers for baggage pieces, comprising: at least two conveyors disposed in vertically spaced-apart planes to define an upper conveyor and a lower conveyor; an elevator having an elevator conveyor and movable in a vertical direction along a travel path between a lower end position in which the elevator conveyor is in alignment with the lower conveyor to form a lower transport path for transfer of articles between the lower conveyor and the elevator, and an upper end position in which the elevator conveyor is in alignment with the upper conveyor to form an upper transport path for transfer of articles between the upper conveyor and the elevator; and a control unit to control the transfer of the articles from the upper and lower conveyers to the elevator and from the elevator to the upper and lower conveyors in dependence on a vertical position of the elevator, said control unit including a signaling assembly having a first signaling member rendered operative to initiate movement of the elevator conveyor, when during movement from the lower end position to the upper end position the elevator has reached an upper trigger position which is defined in the travel path below an upper one of the planes, and a second signaling member rendered operative to initiate movement of the elevator conveyor, when during movement from the upper end position to the lower end position the elevator has reached a lower trigger position which is defined in the travel path above a lower one of the planes.
