ABSTRACT:
A system for the continuous unloading of the containers of pneumatic tranrt vehicles to which an initial velocity is imparted by pneumatic displacement within a transport tube section, while the movement of the vehicles beyond the transport tube section is caused by inertia, the vehicle being suspended from an overhead rail.
The unloading of the vehicle container is performed by operating a latch which engages an uncoupling cam provided on the rail, thus causing the release of the container at its rear end and the pivoting of the container around its axis in the vertical plane while the container remains suspended at its front end. The emptied container is brought back to the initial position by allowing the vehicle to descend along a downward slope of the overhead rail by gravity, while the lower part of the container is lifted by riding on an upwardly inclined plane, so that the latches on the vehicle are coupled with pins provided at the tip of the container in order to hold the container in the initial load-carrying position.
