Abstract: A trap door system for receiving a plurality of articles from a pick and place mechanism, moving those articles to the vicinity of an underlying tray on a conveyor, and dumping those articles on said conveyor in a pre-arranged layout, forming loaded trays, which loaded trays may then be positioned in a frame to form a cube for retort processing of the contents of the articles. The preferred embodiment of the invention contemplates a horizontally situated product gate for receiving a plurality of pouches which are received upon four side-by-side holding slots running the length of the pouch gate by a pick and place mechanism.

Abstract: A system for loading retorts, sterilization systems, and the like. The preferred embodiment of the present system provides both loading and unloading modules, the loading module designed to automatically load fragile containers, in mass and layer by layer into a self-supporting cube array of stacked trays nested in a basket frame. The unloader module automatically unloads the cube array layer by layer after the contents of the cube array are processed in mass. The stack of trays, or batch cube remain as an intact, stacked unit throughout the entire retort process. A hydraulic ram which is associated with each the loader and unloader, lifting the batch cube from the basket frame and indexing the batch cube vertically during the loading/unloading process, respectfully. Each layer in the stack is either loaded or unloaded as that layer is positioned in the home position.
