Abstract: A system for automatically locating barrels at given positions in store-racks with their plugs positioned at the tops of barrels, includes: a pair of rails which may be inclined, and on which barrels are to be placed; a pair of stoppers, each of which may be pivotally movable within a vertical plane and which are adapted to hold a barrel therebetween in their raised portions; a pair of position-adjusting guides positioned externally of the rails; a set of barrel turning discs rotatably mounted on a support which is movable up and down, and by which discs barrels are supported in rotatable relation; a plug-detecting-photoelectric-tube switch; a roller for measuring a maximum circumference of a barrel and the circumference of a barrel at the points of the barrel contacting rails on which the barrel rolls to the given position on racks; and a barrel-position-calculating control circuit. The barrels are of a beer-barrel type and the plugs are sealingly embedded in the shell of a barrel.
