Patent ID: 8689964

Claim:
A piece goods conveyor installation, comprising: a conveyor track with carrying and guiding elements; individual containers for a transportation of piece goods on said conveyor track; at least one drive element disposed on said containers; at least one unloading and loading station for emptying the piece goods out of said containers and for loading each of said containers with the piece goods; deflecting rollers; a load-bearing endless carrying belt defining a bearing surface and spanning each of said containers, said load-bearing endless carrying belt being drivably guided transversely with respect to a direction of transport of said containers around said deflecting rollers disposed on both sides of said containers; a stationary drive disposed in a region of said loading and unloading station, for driving said load-bearing endless carrying belt, said stationary drive which, at least during a loading or unloading operation, can be coupled to said at least one drive element for driving said load-bearing endless carrying belt; said at least one drive element disposed on said container has deflecting wheels and a toothless first flat belt which rotates endlessly around said deflecting wheels parallel to the direction of transport; a transmission belt; said stationary drive having a drive deflecting wheel and a toothless second flat belt rotating endlessly around said drive deflecting wheel parallel to the direction of transport; and at least one of said deflecting wheels of said drive element is operatively connected by said transmission belt to said load-bearing endless carrying belt with said transmission belt transmitting a rotation of said at least one of said deflecting wheels of said drive element parallel to the direction of transport to a rotation of said load-bearing endless carrying belt transverse to the direction of travel, and said first flat belt, in a region of said loading and unloading station, can be brought into frictional connection with said second flat belt, being endlessly drivable rotatably parallel to said first flat belt, and a rotational speed and direction of rotation of said second flat belt can be controlled.
