Claims (1)

[Claims for Utility Model Registration] (1) A stirring shaft that has an opening at the top, a discharge port connected to a plurality of ball sending pipes at the bottom, and is rotatable from the discharge port to a position longer than the diameter of the ball. In a hopper equipped with a hopper, the upper part is provided with a charging port for balls sent by a conveyor, and the lower part is provided with a ball receiving pit that opens in connection with the opening of the hopper,
a bulkhead with a plurality of windows at the bottom of the ball receiving pit;
A ball distributor characterized in that it is provided with a shutter for opening and closing the window. (2) The ball distribution device according to claim 1, further comprising an inclined portion inclined toward the window above the shutter and on both sides or one side of the window in the bulkhead. (3) The ball dispenser according to claim 1 or 2, wherein the surface of the stirring shaft is provided with a plurality of shallow grooves that are long in the axial direction. (4) A hopper sensor is provided above the hopper, a pit sensor is provided above the ball receiving pit, and a signal is received from the hopper sensor when the ball decreases from a predetermined level in the hopper. The shutter is closed and the conveyor that sends balls to the ball receiving pit is operated, and when the balls have accumulated above a predetermined level, the shutter is opened upon receiving a signal from the hopper sensor, the conveyor is stopped, and the ball is sent to the ball receiving pit. When the number of balls has decreased from a predetermined level inside, the shutter is closed in response to a signal from the pit sensor and the conveyor is operated, and when the balls have accumulated above a predetermined level, the shutter is opened in response to a signal from the pit sensor. Claims 1 to 3 further comprising a controller configured to stop the operation of the conveyor.
The ball distributor described in any of the above. (5) The sides and top plate of the ball receiving pit are sealed,
5. The ball distributing device according to claim 1, wherein the top plate is provided with a ball loading port and a ball exhaust port, and the conveyor is comprised of a pneumatic feeding device. (6) Claims 1 to 5, wherein a plurality of discharge ports connected to the ball sending pipe are arranged in two rows at appropriate intervals on the bottom of the hopper, and a stirring shaft is provided at the upper part between the two rows of discharge ports. A ball distributor as described in any of the above. (7) The ball distributor according to any one of claims 1 to 6, wherein the opening of the hopper is located between the two side walls. (8) The ball distribution device according to any one of claims 1 to 7, wherein the bottom plate of the hopper is made of a perforated steel plate having a large number of small holes.
