| 摘要 |
The invention relates to a pneumatic conveyor essentially comprising upstream (1) and downstream (2) tubular transport channels which are interconnected by means of a switch device (3) and a support infrastructure (4). The inventive conveyor is characterised in that the switch device (3) takes the form of a transport and guiding means which is flexible in relation to the longitudinal axis thereof and which consists of a flexible blade. Said flexible blade supports a means (10) for propelling products or bottles (6) to be transported or conveyed, which essentially consists of individual rigid parallelepiped elements (18). One end (3') of the flexible transport and guiding means is fixed to the support infrastructure (4) or to an upstream (1) or downstream (2) transport case, such that the guide part thereof corresponds to that of a downstream (2) or upstream (1) transport case, while the other end (3) of said flexible transport and guiding means is guided with possible angular displacement on the support infrastructure (4) or on an upstream (1) or downstream (2) transport case and is connected to a reciprocating displacement means (5). The invention is particularly suitable for use in the field involving the transport of loads using overhead pneumatic conveyors.
