An automated system for transferring articles from a container. An item transfer system includes a frame configured to receive a first tray and a second tray, a movable paddle assembly, a frame, and a plurality of actuators. The system is configured to transfer articles from the first tray to the second tray by an automated process including securing the articles within the first tray with the paddle assembly, moving a lifting assembly or an item support platform such that the articles are in a slidable configuration relative to the first tray, moving the paddle assembly and/or the item support platform in one or more linear translations to remove the items from the first tray and place the items above the second tray, and releasing the items into the second tray.
