Abstract
This is an improved retrieval mechanism for vending machines that includes a sophisticated positioning system, gripper and trays for improved efficiency in product retrieval and delivery. Following product selection, the positioning system quickly transports the gripper through the X-Y plane to the front of a tray queue containing the selected product. The gripper is extended in the Z-direction, and its fingers grasp the foremost product container in the queue. The gripper is raised in order to clear a retaining lip in the queue and then retracts, and the positioning system transports the gripper carrying the product container to a delivery port. The gripper then releases the product which slides down a chute into a delivery port for customer pick up. Unique product storage trays are provided which work in conjunction with the gripper to allow only the foremost product to be removed from a tray queue. Related methods are also disclosed.
