An upper inlet 110 of the gate cylinder 20 is formed with a suction port 110 directly connected to an inlet nipple 75 connected to a contents storage tank and a tube, and an outlet 120 of the contents is formed at a lower surface of the gate cylinder. This outlet is directly connected to the filling nozzle 70 penetrating the table 80, and the container 90 supplied by the container conveying apparatus is located below the filling nozzle. In addition, a suction port 130 is formed at a side surface of the gate cylinder 20, and is directly connected to the head of the charging cylinder 30.

In addition, the gate cylinder 20 is provided with a gate piston 25 rotating around a cylinder axis, one end of the gate piston is connected to the rotary pneumatic cylinder 10 and the other end is inserted into the gate cylinder. Two circular holes 140 and 150 are formed at a predetermined angle from the surface of the gate piston to the center of the shaft, and the suction through-hole 140 that meets the inlet 110 of the gate cylinder when the gate piston rotates is formed. And a discharge through-hole 150 that meets the outlet 120 of the gate cylinder.

In addition, a filling piston 35 of a no-packing type is inserted into the filling cylinder 30 to which the side portion and the head portion of the gate cylinder 20 are connected, and an adjustment handle provided at the rear portion of the filling piston is movable plate 45.

Therefore, the vertical reciprocating motion generated by the cam drive device (not shown) causes the vertical drive shaft to reciprocate up and down, resulting in a cycle in which the table 80 moves up and down.

The automatic filling apparatus of the present invention configured as described above can fill a quantity of contents in a container of a small capacity continuously supplied. First, the filling step is as follows.

That is, when the container 90 is supplied to the predetermined position by the container transfer device, the upper and lower drive shafts 95 supporting the table 80 of the automatic filling device 100 are lowered by the cam drive to fill the filling nozzle. 70 approaches the bottom surface of the vessel 90. At this time, the rotary pneumatic cylinder 10 connected to one side of the gate piston 25 starts the rotational movement to rotate the gate piston 25 by a predetermined angle to align with the outlet 120 formed in the gate cylinder 20. In accordance with this, a passage for discharging is formed. The alignment operation with the outlet port and the suction port of the gate piston 25 will be described later in detail. Thereafter, the filling pneumatic cylinder 40 moves forward to move the filling piston 35 toward the head of the filling cylinder 30, and as a result, the contents sucked into the filling cylinder are discharged formed in the gate piston 25. The filling process of discharging to the passage is performed. While the filling is in progress, the cam driving device installed at the lower side is driven to move the upper and lower driving shafts 95 to the upper side, and the contents of the liquid sucked into the filling cylinder 30 are filled in the container through the discharge port. The charging cycle ends immediately before the rise of 80) reaches a peak.

When the filling cycle is finished and the table 80 is raised to the highest point through the ascending operation, the filling nozzle 70 comes out of the container 90 and a new suction cycle is started. That is, when the table 80 is raised to the highest point, the rotary pneumatic cylinder 10 connected to the gate piston 25 starts the reverse rotation movement to rotate the gate piston 25 in the reverse direction, the gate piston 25 is The rotational movement forms a passage for suction by aligning with the suction port 110 formed in the gate cylinder 20. After the suction passage is formed in this manner, the filling pneumatic cylinder 40 moves backward to move the filling piston 35 toward the rear of the filling cylinder 30, and as a result, the contents of the contents storage tank are gate pistons. A suction cycle for suctioning into the empty space in the filling cylinder 30 is performed through the suction passage formed by 25. At the end of the suction cycle as described above, the above-described filling cycle can be started again, so that the suction and filling can be automatically and continuously performed to quantitatively fill the contents in the container 90 conveyed by the transfer device. do.
