Abstract

Systems and methods for filling a customer order. An automated label and verification machine is used to print and apply patient labels to products containing medical items and then verify the product label and patient label on each of the products. In order to supply the automated label and verification machine with a batch of different products making up the customer order, a user is sent to a storage carousel and prompted to pick the products from storage locations rotated into location adjacent to a door in the cage surrounding the storage carousel. The use of the storage carousels maximizes the number of distinct products and amount of those products that may be stored in close relation to the automated label and verification machine, thereby making the process more space and time efficient.
