Abstract:
Chain store comprising two continuous chains which together carry gondolas serving for holding goods and are driven together by gear wheels or chain wheels rigidly connected to one another, each chain being guided by means of upper and lower stationary deflection pulleys, on the one hand a loading station and on the other hand an unloading station being provided on the two outermost sides of the chain, and one drive device each being coordinated with the loading and unloading side, which device in each case drives the lower or upper stationary outermost deflection pulley coordinated with the loading or unloading side, whereineach chain is guided in the region of the loading station around two stationary deflection pulleys and over two deflection pulleys, each of which is mounted freely rotatably in a vertically displaceable carriage, in such a way that the chain passes in each case from the outermost, upper or lower deflection pulley mounted freely rotatably in the first carriage downwards or upwards, respectively, to a further stationary deflection pulley and from there perpendicularly upwards or downwards, respectively, to the next upper or lower deflection pulley mounted in a stationary manner, that it passes in each case from the second outermost lower or upper stationary deflection pulley perpendicularly upwards or downwards, respectively, to the deflection pulley of the second carriage and from there perpendicularly downwards or upwards, respectively, to the lower or upper outermost deflection pulley mounted in a stationary manner, the two carriages are arranged one on top of the other in a staggered manner and are additionally connected to one another by means of at least one chain, one belt or one tackle, which chain, belt or tackle is guided around an upper deflection pulley mounted in a stationary manner, and a drive device is provided for separating the movement of the chain during loading into a chain movement which has a high frequency in the region of the loading side and an adjacent continuous or low-frequency chain movement.
