A conveyor path comprising three conveyors, namely, a first conveyor disposed at the delivery point, a second conveyor disposed on the build-up stretch, and a third conveyor disposed at the outlet or pick-up point; and further comprising a driving mechanism which enables the second conveyor to be driven independently of the two other conveyors in backward direction, or in conjunction with one of the other conveyors, or both of them, in forward direction; the driving mechanism controlled by a switching arrangement actuated by the passing goods so that, during delivery, the goods accumulate or "build-up" at the beginning of the build-up stretch and, during the release of goods, the goods accumulate at the end of the build-up stretch. In the case of alternating delivery-release operation with an incompletely occupied build-up section, all the goods accumulated at the end of the build-up stretch are shifted to the beginning of the build-up stretch when the delivery station is occupied, whereas the goods present in the above configuration are shifted to the end of the build-up stretch when the pick-up station has been cleared of goods. |
