Apparatus for unloading pallets of building components from racks.

摘要

In a plant for making concrete roof tiles, the tiles are loaded on to racks (30) and cured in a curing chamber (6). Apparatus for unloading the tiles on their pallets (P) from shelves in the racks on to an outfeed conveyor (40) comprises a descending conveyor means (574, 576) having pairs of supports (598), the spacing of the pairs of supports being equal to the spacing of the shelves. A pusher (604) moves columns of tiles from the shelves on to the pairs of supports which engage the edges of the tiles. A cam (706) moves the descending conveyor away from the rack and the conveyor then is activated to deposit the tiles on to an outfeed conveyor in spaced relationship.
