  • Particulate material supplying apparatus with a downwardly slanting discharge gutter which rotates side to side
    Patent number: 10059536
    Abstract: A particulate material supplying apparatus includes a hopper that stores a particulate material, a discharge gutter that dispenses the particulate material, a feeder that transports the particulate material to a weighing scale, the weighing scale that weighs the particulate material, a supply shutter that feeds the particulate material to a machine in the next process step at a predetermined timing, and a controller that controls the operations of these devices. The discharge gutter includes an inclined gutter portion having an opening in an upper surface thereof and a substantially U-shaped cross section. The controller controls the discharge gutter so that the particulate material in the hopper is dispensed to the feeder by causing the discharge gutter to perform a swinging motion in which a forward rotation and a backward rotation each to a predetermined angle are repeated while the opening in the inclined gutter portion faces upward.
