Arrangement for conveyor systems which are intended to transport objects (19) to particular places, for example work stations (4). The system comprises an upper transport level with conveyor arrangements which are so adapted as to transport the objects in an essentially horizontal direction and a lower level, at which the work stations are situated, with a second conveyor arrangement so adapted as to transport the objects between the upper level and the lower level for the transport of the objects to the work stations from the upper level and from the work stations to the upper level for onward transport in the latter. The second conveyor arrangement comprises a number of chains (28) which extend in the form of endless loops between the upper and the lower level. They are advanced by chain wheels (30) for the transport of the objects between the levels. Near the work stations are arrangements for transferring the objects from the first to the second conveyor arrangement (21) and, once they have been transported to and away from the work station, for returning them to the aforementioned conveyor track (23) with the help of arrangements (54) for the transfer of the objects between the conveyor arrangements. |
