<p>PURPOSE:To improve the efficiency of the captioned fluid shelf system by starting the operation of conveyor means with the aid of external operation on the side of delivery in said system with use of intermittent compressed air supply. CONSTITUTION:Optical sensors 27, 28 are provided on a warehousing port 12 and a delivery port 15, and an L level is ordinarily inputted into a control unit by outputting a H level when a fork lift approaches the sensor. Started delivery work owing to fork lift approaching the delivery port 15, the sensor 28 changes to the H level, whereby a S-RFF circuit 31 is set via an OR circuit. Then, changed the sensor 28 to the L level due to separation of the fork lift after completion of the delivery work, the control unit conducts a current through a solenoid coil 48 via inversion of the S-RFF circuit 31 from the H level and a NOT circuit 32 being kept at the H level for opening a compressed air control valve supplying compressed air and for thereby starting conveyance. With such arrangement, efficiency of the system can be improved.</p> |
