Abstract
A pneumatic tube conveyor station serves for receiving conveying cases (12)rriving from a forwarding tube (11) and having a high weight of, for example, 12 kg and a high travelling speed of, for example, 7 m/s. The conveying cases (12) are initially braked in a rotatable intermediate store (15) and are then transferred, after the intermediate store (15) has been rotated, to a unloading position (56). The intermediate store (15) is arranged in a position above the forwarding tube (11) and the unloading position (56). The intermediate store (15) and the unloading position (56) are connected one with the other by a substantially vertical tube section (40, 41, 55).
