Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION The present invention relates to an improvement in a liquid filling valve, and an object of the present invention is to make it possible to efficiently fill liquids containing solid substances such as fruit grains and pulp.

Conventional technology Conventionally, a flow valve is provided on the top of a conical spreader fixed to a filling cylinder so as to be able to move up and down, and a conical liquid circulation gap formed between the two is opened and closed to transfer the liquid in the liquid storage tank into the filling container. Liquid filling valves that perform flow-down filling have the advantage of being able to form a large discharge port diameter and allowing smooth flow-down filling of liquid, but because the exhaust hole is located in the center of the spreader, it is difficult to add particles such as fruit grains and pulp. When a filling container is filled with a liquid or a liquid mixture of these particles, particles such as fruit particles enter the exhaust hole due to the flow of the filling liquid, causing a clogging phenomenon.

This is because the liquid filled in the conical liquid flow gap forms a conical thin film, flows down from the inner wall of the filling container to the center of the bottom, and then flows up the center of the container. This is because it is very easy for particles such as fruit grains to enter the open exhaust hole.

Structure of the Invention The present invention is designed to easily and reliably prevent clogging of the exhaust hole due to fruit particles, etc. in a liquid filling valve using such a conical spreader, thereby improving filling accuracy and obtaining high quality products. The first invention is a filling cylinder in which a rod having a conical spreader at the lower end is fixed to the center thereof, and a flow valve which is urged downward by a spring and whose lower end is supported on the upper part of the spreader is fitted. An exhaust pipe communicating with the gas phase portion of the liquid storage tank is provided on the peripheral side of the flow valve, and an annular flow passage formed between the shaft rod and the flow valve is provided on the exhaust pipe side of the lower part of the shaft rod. The gist is that the obstructing branch piece was fixed,
In the second invention, a flow valve, which is urged downward by a spring and whose lower end is supported on the upper part of the spreader, is fitted into a filling cylinder which has a rod fixed at the center and has a conical spreader at the lower end. An exhaust pipe communicating with the gas phase portion of the liquid storage tank is provided on the circumferential side of the valve, and a branch piece is provided on the exhaust pipe side of the lower part of the shaft rod for closing the annular flow passage formed between the shaft rod and the flow valve. is fixed, and a cross section is formed between the inner circumference of the lower end of the exhaust valve, which is supported by the lower part of the spreader support of the flow valve and the lower periphery of the conical spreader, and is urged downward by the spring, and the lower part of the conical surface of the spreader. forming a triangular annular gap,
The gist is that the annular gap is communicated with the exhaust pipe.

An embodiment of the present invention will be described with reference to the drawings. A filling cylinder 2 fixed to the lower part of an annular liquid storage tank 1 has an engaging portion 3, and a flow valve 5 is elastically biased downward by a spring 4. A conical spreader 7 is integrally formed at the lower end of the shaft rod 6 which is fitted into the upper part and fixed to the center of the filling cylinder 2, and the lower end of the flow valve 5 is closed and supported by the upper circumferential surface of the conical spreader 7. Furthermore, a fan-shaped branch piece 8 is fixed to one side of the lower part of the shaft rod 6 so as to close a part of the annular flow passage a formed between the shaft rod 6 and the flow valve 5.

Further, an exhaust valve 11 is fitted into the lower outer side of the flow valve 5 and has a locking part 9 that can be freely engaged with the engaging part 3 and has a container seal pad 10 at the lower end. It is biased downward by a spring 12 screwed onto the filling cylinder 2, and its lower end is supported by the lower peripheral edge of the spreader 7.

An exhaust pipe is provided on the circumferential side of the flow valve 5 located outside the fan-shaped branch piece 8 provided on the shaft rod 6, the upper end of which opens into the gas phase part of the liquid storage tank 1, and the lower end of which opens into the spretzder support. 13 is provided, and the lower end of the flow valve 5 in contact with the spreader 7 is cut obliquely to form an annular gap b having a triangular cross section between the exhaust valve 11 and the spreader 7. A notch 14 communicating with the annular gap b is provided at a position facing the exhaust pipe 13.

Further, at the upper end of the exhaust pipe 13, a screen 15 such as a mesh plate for preventing solid matter from entering is removably provided. Note that in the figure, A is a filling container, and 16 is a sealing member.

Since the embodiment of the present invention is constructed as described above, when the filled container A lifted up by a lifter (not shown) collides with the container seal pad 10 and causes the exhaust valve 11 to rise while compressing the spring 12, The locking part 9 collides with the engaging part 3 of the flow valve 5 and lifts up the flow valve 5, and the lower end part that collides with the spreader 7 separates upward from the spreader 7 and lifts up the flow valve 5. 1
The liquid inside passes through the annular flow passage a to the spreader 7.
The conical surface of the liquid is formed into a film and is filled into the filling container A, and a part of this flowing film-like liquid is separated by the fan-shaped branching piece 8 to form a vent in the downstream film. The air in the filling container A is exhausted through this vent into the gas phase of the liquid storage tank 1 through the annular gap b and the exhaust pipe 13, and then the filling liquid rises into the exhaust pipe 13 and exits the liquid storage tank 1. Filling is carried out until it matches the liquid level in the tank.

When filling is completed in this way, the filling container A begins to descend and as the exhaust valve 11 descends, the flow valve 5 descends and is supported by the spreader 7, and then the liquid in the exhaust pipe 13 also falls into the filling container A and is filled. The action ends.

Effects of the Invention The first invention is a conventional liquid filling method using a conical spreader, in particular, an exhaust pipe is provided on the circumferential side of the flow valve and opened on the lower end circumferential side, and a flow valve is provided on the exhaust pipe side of the shaft rod. Since a branch piece is provided that closes a part of the formed annular flow path, the opening of the exhaust pipe follows the flow direction of the filling liquid that flows inside the filling container along the peripheral wall, passes from the bottom through the center, and rises up the center. The container is located on the peripheral side in the downward flow direction of the filling liquid to prevent particles such as fruit particles and pulp from entering the exhaust pipe as much as possible, thereby causing clogging. On the other hand, the branch piece forms a vent in the part of the liquid film that flows down into the filling container in the form of a thin conical shape of the spreader, thereby smoothly and reliably exhausting the inside of the filling container. The filling operation can be performed easily and efficiently.

Further, the second invention forms an annular gap between the flow valve, the exhaust valve and the conical spreader,
Since this was connected to the exhaust pipe, the exhaust air
This is done smoothly and reliably without being blocked by particles such as fruit pulp, and since the pressure inside the container is reduced, when the container separates from the seal pad, the residue on the spreader surface is forcibly sucked into the container and the flow valve and The exhaust valve can perform a reliable opening/closing action on the spreader surface, which further promotes the formation of a ventilation section by the branch piece and the exhaust during filling of liquid containing seeds, fruit pulp, etc., and the filling action. can be done efficiently.

Therefore, the present invention can reliably prevent solids such as fruit particles and pulp from flowing back into the filling valve and liquid storage tank, and can also reliably open and close the flow valve and exhaust valve, allowing for highly accurate filling and filling. It has excellent features such as being able to produce high quality products and also being able to fill only liquid.
