A freestanding conveyor personnel gate includes a support or base portion and a conveyor portion, which is pivotable and movable relative to the support between a closed position and an open position. The gate includes a latch mechanism which is operable to latch the gate in both the open and close positions. The latch mechanism is operable via a handle which is movable in either direction to disengage the latch mechanism and to raise or lower the conveyor portion toward its open or closed position. The conveyor portion is balanced and supported via a strut member which is pivotally mounted at the conveyor portion and the support portion. A biasing member is provided to bias the conveyor portion toward its closed position when the conveyor portion is moved past a neutral point between the open and close position. The biasing member is further operable to bias the conveyor portion toward its opened position when the conveyor portion is moved past the neutral position toward the open position of the gate. The biasing member thus self propels the gate toward its opened or closed position, while the latch mechanism locks the gate in the respective position once that position is reached by the conveyor portion.

Conveyor personnel gate

The present invention relates to a bi-directional transfer mechanism which is driven by the drive shaft of a conveyor system. The transfer mechanism includes a pair of vertically displaceable lift tables with a conveying member reeved thereon such that the conveying member is driven in one direction on the first lift table and in a different direction on the second lift table. By selectively displacing the first and second lift tables between an engaging position whereby the conveying member is displaced above the conveying surface of the conveyor system and a non-engaging position whereby the conveying member is displaced below the conveying surface of the conveyor system, the transfer mechanism can transfer articles in two directions.
