Abstract
PURPOSE:To eliminate the waste of supplying volume by measuring aggregate volume to be supplied to aggregate storage bins and the aggregate volume to be delivered, computing the measuring difference value timely and supplying the volume covering the difference value. CONSTITUTION:In case the aggregate volume in aggregate storage bins 5a-5e is decreased by discharging aggregate and the storage is equalized to the set space volume value or less, a space signal is issued from a CPU 20, instructing to start the supply of aggregate. On the other hand, when the actual storage volume in the aggregate storage bins 5a-5e reaches a set space volume value in supplying the aggregate from an aggregate hopper, a space volume signal is issued from a main CPU 20 to open a gate for drawing out the aggregate onto a drawing conveyor 3 and sensed and measured by a load cell 17 and supplied. Thus, as the difference value of actually stored volume from the set volume value only is always supplied to the hopper, the aggregate can be supplied efficiently.
