10 is a cross-sectional view of the above-described beverage quantity supplying device in a suction stroke. 11 is a view showing the state of the valve unit when the suction stroke is performed.

First, in order to inject the solution into the container 2 in a fixed amount, the solution is first filled in the storage tank 10. 7, the user adjusts the stroke of the cylinder rod 240 through the rotation operation of the stroke adjusting unit 100 as shown in FIG. 7, The volume of the solution injected into the container 2 can be determined by adjusting the volume inside the space 411.

When the solution is filled in the storage tank 10 and the volume of the solution to be injected is determined, the beverage dosing device 1 is driven. The storage tank 10 is rotated together with the injection device 20 and the transfer device 30 so that the guide roller 251 rolls along the cam track 40.

Then, the spool lever 430 rotates counterclockwise through the second lever guide 52 immediately before proceeding to the suction stroke, and the state is as shown in FIG. In this state, the suction passage 422 is communicated with the inflow passage 412 by the rotation of the spool member 420.

The rotation of the injection device 20 causes the guide roller 251 to roll along the cam track 40 and move the guide block 250 upward. The piston unit 300 is also lifted in accordance with the upward movement of the guide block 250 and the suction force is generated in the inflow space 411 due to the upward movement of the piston 320. Therefore, the solution in the storage tank 10 can be continuously introduced into the inflow space 411 through the suction channel 422 and the inflow channel 412 in order.

Since the outflow channel 413 is blocked by the outer surface of the spool member 420, the inhaled solution can be collected in the inflow space without being discharged.

When the guide roller 251 is positioned at the uppermost end of the cam track 40, the piston 320 is in a state as shown in FIG. 10, and the solution flows into the inflow space 411 And the suction stroke is completed.

Although the filling passage 423 is in communication with the outflow passage 413, the nozzle 440 is kept closed by the check valve 441 in the nozzle 440, Can be prevented from flowing out through the nozzle (440).

Next, when it is sensed that the injection device 40 is further rotated by a predetermined angle or is located at a specific position, air is supplied to the cylinder block 230 for driving the cylinder assembly 210 do. When air is supplied to the cylinder block 230, the cylinder assembly 210 is driven. When the cylinder assembly 210 is driven, the cylinder rod 240 moves downward.

The guide block 250 and the piston unit 300 are moved downward by the downward movement of the cylinder rod 240 and the piston 320 is moved downward from the inside of the inflow space 411 . Accordingly, the pressure in accordance with the movement of the piston 320 is applied to the interior of the inflow space 411, and the check valve 441 of the nozzle is opened. When the check valve 441 is opened in the nozzle 440, the solution in the inflow space 411 is sprayed through the nozzle 440 and can be supplied to the inside of the container 2.

The downward movement speed of the cylinder rod 240 is controlled by the speed of the injection device 20 moved along the curvature of the cam track 40 so that the guide roller 251 and the cam track 40 do not interfere with each other. And can be set to move downward while maintaining a corresponding speed.

Of course, as soon as the guide roller 251 is positioned at the lowest level of the cam track 40, the cylinder assembly 210 instantaneously operates according to the need to pressurize the nozzle 440 ) To quickly spray the solution.

When the injection device 20 makes one full rotation, the suction stroke and the filling stroke are completed, and one cycle is performed per one rotation. Therefore, a plurality of containers 2 provided in the transfer device 30 are injected with a predetermined amount of solution into all of the containers 2 during one revolution of the injection device. When the filling operation is completed, the container 2 is separated from the conveying device 30 and is automatically discharged and conveyed toward the next operation, so that the new container 2 can be continuously supplied to the conveying device 30 do.

That is, the injection apparatus 20 is continuously rotated, and the procedure described above is repeated to inject a set amount of the solution into the new vessel 2 again, and this operation can be continuously and continuously performed.

Meanwhile, when it is desired to adjust the amount of the solution injected into the container 2, the injection amount of the desired solution can be set by operating the stroke adjusting unit 100.

When the operation of the beverage quantity feeder 1 is interrupted for a long period of time or maintenance and maintenance such as cleaning or sterilization of the valve unit 400 is required, And the piston 320 can be separated and operated.
