Abstract: A food storage and delivery device is formed of a reservoir for food items, a holding and transferring section situated adjacent to the reservoir, an ascending section for moving the holding and transferring section, and a controlling section for controlling the device. After positioning the holding and transferring section to one side of the storage and delivery sections at a predetermined vertical level by means of the ascending section based on a delivery command, the food item is delivered from the storage and delivery section to the holding and transferring section to hold the food item temporarily. After positioning the holding and transferring section to a vertical level corresponding to a delivery portion, the temporarily held food item is delivered to the delivery portion. The food items can be automatically and quickly delivered.

Abstract: A storage and delivery device for packed foods retained in containers is formed of a plurality of shelf cases each having a plurality of vertically oriented shelves for retaining the containers thereon, a storage shed for retaining the shelf cases therein and having a cyclic-moving device for cyclically moving the shelf cases horizontally along a horizontal closed loop, a processing device for processing the packed foods in the containers, and a robot. When an order is received, the robot takes out the container from the shelf of the shelf case and transfers the container to the processing device for processing the packed food. A storage room retains the storage shed, the processing device and the robot. The containers with the foods can be stored and automatically delivered after processing.
