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 put on the main structure for controlling the presence of packages in each module independently of the induction sensors. Presented examples of possible solutions for rack stores designed according to the described concept, reveal numerous advantages, and theseare listed below. The solutions allow for exploitation of repetitve elements (loadcarying structures, mechanisms and drives with the appropriate control systems), in the construction of the rack stores with varying size and application. The rack stores can be built as one-sided (no through) as well as two-sided (through) stores, with varying numbers of entry and exit levels. In case of failure (and also during maintenance), the structural solution of the one-sided rack store and its control system ensures access to the interior parts of this store and to the packages there present, and also allows to switch off the defective segment without disturbing the work of the remaining segments. Control systems , which are especially configured, enable the functioning of the rack stores in both partly and fully automated systems of flow of packages and materials.
