Abstract
An autonomous grid storage system (1) with a foam based fire prevention system. The autonomous grid storage system is in the form of a grid storage structure (104) dived into sub grids (10A, 10B, 10C) separated by firebreak or firebreaks (12). A foam dispensing system (20) dispenses a fire-retardant foam into the firebreak or firebreaks in the event of fire.
Claims9
An automated grid storage and retrieval system comprising:
- a storage grid structure comprising a rail system comprising a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and a second set of parallel rails arranged in the horizontal plane and extending in a second direction which is orthogonal to the first direction, which first and second sets of rails form a grid pattern in the horizontal plane comprising a plurality of grid cells, each grid cell comprising a grid opening defined by a pair of rails of the first set of rails and a pair of rails of the second set of rails;
- a plurality of vertical members defining a plurality of storage columns arranged into a storage grid, each storage column being arranged to store a respective stack of storage bins, wherein the storage columns are located beneath the rail system, wherein each storage column is located vertically below a respective grid opening;
- wherein the storage grid structure is arranged such that a plurality of bin handling vehicles are operable on the rail system for collecting and returning the storage bins to and from the storage columns, said bin handling vehicles being controllable by a control system for monitoring and controlling the automated grid storage and retrieval system,
- wherein the storage grid structure comprises a plurality of sub grids and one or more firebreaks, wherein the sub grids are separated by the one or more firebreaks, and
- wherein the one or more firebreaks each comprise a set of storage columns, of the plurality of storage columns, that are devoid of storage bins and that form an entire row of the storage grid, and that are structurally identical to storage columns, of the plurality of storage columns, arranged to store the respective stacks of storage bins;
- and
- a foam dispensing system arranged in connection with the one or more firebreaks and configured for dispensing a fire-retardant foam into the one or more firebreaks in an event of a fire.
