Method for retrieving items from a storage system and storage system for storing and retrieving bins

摘要

A cooled storage system comprises a grid structure of storage cells, where each cell is arranged to accommodate a vertical stack of storage bins and having a top level, a plurality of remotely operated vehicles arranged to move at the top level of the grid structure and receive a bin from a storage cell at the top level of the grid structure, where there is provided thermal insulation between at least a section of the grid structure and the remotely operated vehicle, and said section of the grid structure has a temperature that is lower than the temperature of the remotely operated vehicle. The vehicles, upon receiving a signal to retrieve a bin, are commanded to form a train of vehicles that moves sequentially over a target stack, thereby essentially covering the open stack during the retrieval operation in order to reduce thermal losses during the retrieval operation.
