Vertical carousel and vertical lift module position indicator system

Abstract

A storage and/or retrieval system such as a Vertical Carousel (VC) or Vertical Lift Module (VLM), which has a common light source or light source grid, consists of LED's and the like incorporated into the body of the machine in proximity to the access point operator's workstation. When a storage carrier/tray is delivered to the access position, the common light source transmits light through one of a light transmitting element to an access face of the storage compartment position in relative proximity to the actual compartment's position. The light transmitting devices can be arranged in patterns dictated by the type of storage required (i.e., the number of compartments within the tray can vary in size and number) individually for different trays, and are delivered over a grid pattern of light sources for annunciation.
