PURPOSE:To prevent wild flow of articles by appropriately controlling stoppage of compressed air supply to an air hose in the captioned system provided with a roller unit which appears or disappears, according to inflation or contraction of the air hose, in a groove of a longitudinally and slantingly provided rail. CONSTITUTION:A flow shelf system is composed of the plural number of slantingly laminated stages of rail 11 forming a groove 16 which is provided therein with an air hose 20 and a roller unit 19, composed of a roller group 17 and a supporting body 18 rotatably supporting said group 17. By inflating the air hose 20 by supplying compressed air, the roller unit 19 is pushed up and a pallet 14 is transferred along the slanting direction of the rail through the roller group 17 by means of gravity. In this case, as control devices for the captioned system, two timers setting a time for compressed air supply are provided. In case a time for compressed air supply set by the first timer exceeds the same set by the second timer, compressed air supply is stopped according to output of the second timer. |
