Concept for one-sided modular FIFO rack stores
Języki publikacji
The concept for modular rack stores with one-sided access, which allow therealisation of the „fi-fo" principle of package flow in partly or fully automated storage systems is presented. In accordance with the modular assumption, the storage system consists of repeatitive segments possessing independent load-carrying structures, mechanisms for horizontal and vertical transport of packages, drives, sensor and control systems, which ensure independent functioning of these segements as one-sided „fi-fo" rack store, or group functioning as the appropriately larger „fi-fo" rack store. The individual parts of these segments (the load carrying structure, mechanisms, etc) also have, to a certain degree, a modular structure, which allows them to be made larger by assem-blying additional segements. The smallest basic segment contains a 2-level rack (an upper level for entry and a lower one for exit of packages) as well as a lift for lowering the packages to the exit level. Such a segment can contain 4 packages maximum, including 2 packages in the lift and 2 inside the entry and exit racks. An extension of the segment in legth and in depth, i.e., an increase in the number of levels and lengths of rack channels, means an increase in the volume of the store segment due to the newly created spaces in increased rack and in lift shaft, which is equipped with transposeable supporting elements and can accommodate packages followly lowered by the lift table located under them. For a given strength of the foundation, the maximum height and depth (length of the channels) of an individual store segment is limited by the size of the total mass (brutto with packages) of the part that is transported in order to gain access to the interior of the rack store. All mechanisms that transport packages in the modules of the store are electricaly powered and are equipped with pneumatically driven blocades of packages, as well as strain gauges
