Monorail jig box loader

摘要

An automated system is provided for stacking brick in monorail jig box stacking systems. The apparatus includes a plurality of loader subassemblies which sequentially position layers of brick in a jig box supported by a monorail. Each loader assembly includes a supply conveyor operable to consolidate spaced groups of brick in one direction and a marshaling conveyor operable to consolidate groups of brick in a direction perpendicular to such one direction. The two conveyors operate to rearrange the brick so that groups or layers are produced which are sized to provide one full layer in the jig box. A transfer tray receives the layers from the marshaling conveyor and extends to carry such layers into the jig box. A stripper retains the layers in the jig box as the transfer tray is retracted. Camming surfaces carried by the transfer tray ensure that the jig box is properly positioned with respect to the tray before the layer of brick enters the jig box.
