Abstract
A method and apparatus of unloading a container having shelves at different levels, each shelf being filled with at least three adjacent stacks of trays filled with a product, such as eggs. The container is comprised of four vertical angle sections connected by horizontal sections which support the stack carrying shelves. The middle stack of trays is always removed first, after loosening that stack by moving it slightly sideways to prevent jamming with the outer adjacent stacks of trays. In one embodiment, a fork-shaped unloading device is used for the unloading, which device can be inserted under tunnel-shaped openings of the lowermost tray of a stack of trays, and the points of which are provided with switch elements or sensors to sense the edge of the shelf. A beam, with electromagnets, is used to lift a superadjacent shelf so that stacks of trays can be unloaded from a subadjacent shelf.
