Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a liquid supply device in a reverse pressure type liquid filling machine.

In conventional counter-pressure liquid filling machines, the filling liquid in the rotating filling liquid pole is suppressed in the radial direction by centrifugal force, making it difficult to distribute the filling liquid to the filling section, and the filling section has more liquid than other sections. Not only does the surface drop and the head pressure fluctuates during filling, making it impossible to obtain accurate flavor, but it also tends to foam due to liquid level waves.
In addition, the liquid level control device operates frequently, causing the supply pump to start and stop frequently, making it difficult to maintain a constant pressure inside the filling liquid ball, and the filling valve protruding into the filling liquid ball. There is also a defect that the filling liquid cannot immediately follow the rotation or stoppage, and the filling liquid is agitated, causing turbulent flow and causing foaming.

In addition, air mixed in the exhaust gas from the container enters the upper space of the filling liquid ball and is absorbed into the filling liquid, which is particularly undesirable when the liquid is easily oxidized such as beer.

In order to improve these defects, filling pulp is attached to the outer surface of the filling liquid ball, and filling liquid is distributed from a distributor to each filling valve. Although it is possible to reduce the agitation of the filled liquid caused by the protrusion, the return gas containing the atmosphere from the container enters the space of the filled liquid ball or the destroyer, so it is difficult to maintain hygiene by absorbing air and introducing outside air. At present, the above problems are still unresolved.

The present invention has been made to improve these deficiencies by providing an upper part of a rotating distributor which is connected to a fixed filling liquid tank and is filled with filling BY and is separate and independent from said filling liquid tank. Connecting to the side of the rotating filling valve connects the upper end of the filling valve to a top counter channel having an exhaust valve, and further connects the top counter channel to a tank counter formed at the top of the filling liquid tank. The gist of this is that it is connected to a pressure chamber.

According to the drawings of the embodiment of the present invention, a rotating disk (2) to which a circumferential pressure casing (1) is fixed has an annular distributor (3) in its center that is filled with a filling liquid. ) and the substantially central portion of the casing (11) are connected by a conduit (4).

i r: A valve base (6) having a seal member (5) on the lower end surface is fixed to the lower part of the casing ill, and a flow valve (
a valve stem (9) having a spreader (8) and a spreader (8);
) supports Ell (10) and umbrella-shaped stopper +il
It is supported by l for vertical movement.

The valve base (

In addition, a vent valve (21+) is inserted into the upper part of the vent passage (20) extending through the center of the valve stem (9) so as to be openable and closable, and the upper end of the vent valve (21) has an engaging part at the upper part. (Pull-down camping member with 22
A flow valve is inserted into the pull-down cap member (231) and urged downward by spring C2 (a), and between the pull-down cap member (231 and the valve stem (9) is a flow valve that urges the valve stem (9) downward. Seal spring (251 is tensioned,
Furthermore, the valve spring +261, which is weaker than the Lupusir spring C251, is stretched over the valve stem (9) to urge it upward.

The upper end engaging part of the pull-down camp member (c) (2) is a lever shaft 0η pivotally supported on the upper part of the casing (1).
The outer lever (291) provided at the outer end of the lever shaft (2) is formed so that the Y-shaped lever (c) provided at The upper end is the conduit (to) and the annular top counter channel (to) above the center of the rotating disk.
311 and the top counter channel 3B
is connected to the atmosphere via an exhaust valve (321).

However, the 7th channel (161), the pre-counter channel α wing and the top counter channel (
31) are rotary joins - 311 + 3 bells 1
3! It is formed to rotate together with the rotating disk (2) via +1, and the sniff channel scream is connected to the conduit (
g), the center 1lII (37) communicates with the snift collection tank C39, which communicates with the atmosphere outside the filling chamber via a conduit (38), and pre-counter channel a! J is a conduit (4I,
The upper central pipe f41) is connected via a conduit (421) to a counterpressure supply device (not shown).

Further, the distributor (3) has a tank counter pressure chamber (43) formed in its upper part, and a central pipe (43) in the lower pressure part of a fixed filling liquid tank (44) which is controlled so that the liquid level is located higher than the distributor. 4 gulls are connected via a conduit (4G) and the filling liquid tank (
The tank counter pressure chamber G131 of 44J is connected to the top counter channel Ill via a conduit (471, upper central cylinder G+81 and a conduit (491), and is further connected to the tank counter pressure chamber (4th floor and the conduit +4).
2) is connected by a conduit 6 having a pressure reducing valve 50), a check valve 511 and a counter air supply valve.

The operation of the snift pulp 0, pre-counter valve aη, and outer lever (21) is performed by a cam whose tilting is also not shown.

Since the embodiment of the present invention is configured as described above, when the container to be filled comes into contact with the sealing part It (5) and is sealed, the pre-counter valve (171) is opened and the pressure in the tank counter pressure chamber (43) is opened. At the same time as higher pressurized gas is supplied into the container, the snift valve is also opened, and the air inside the container is pumped through the snift channel A61 to the collection tank (31) outside the filling chamber, and is exhausted to the atmosphere after pre-gunning. Valve an and Sniftbulg ([41 closes.

Next, the pre-counter valve a71 operates and opens again, supplying pressurized gas into the container, and then the outer lever (marked 2) operates and pulls up the pull-down cap member (c) with the Y-shaped lever (to) and pulls up the vent valve (2). ] When 1 is opened, the pressurized gas in the container flows from the vent passage (2 (11) to the upper part of the casing (1), and the upper part of the casing (1) is the filling liquid tank (4.
0 tank counter pressure chamber (4~), the pressure inside the container instantly becomes the same as that of the filling liquid tank (44).

Next, the flow valve (7) is pulled upward by the pulp stem (91) and opens to start filling the container, and as the filling liquid flows down, the pressurized gas in the container flows through the vent passage ( From 20I to the conduit!301, through the top counter channel Cl1l to the exhaust valve (321
released from.

However, at this point, 70-bulg seal spring (
25) is held in a free state.

In this way, the filling liquid is filled into the container, and the liquid level rises to the bottom of the vent tip (9) at the lower end of the valve stem (9), forming a taste line, and then further vent passage (2).
01 and reaches the level of the liquid in the filling liquid tank (44), filling stops.

Then, the outer lever (c) lowers the pull-down cap member and releases the flow valve seal spring (25).
), only the flow valve (7) is closed, and then the pre-counter valve (171) is activated again and opens, pressurizing the inside of the container with pressurized gas from the pre-counter channel 061 and draining the upper excess liquid from the vent tip (9)'. is pushed back from the vent passage (21) to the upper part of the casing (1), then closes the pre-counter valve (171) and closes the vent valve (
211 is also closed, and finally the sniff valve α is activated to open the container and release the inside of the container to the atmosphere through the snift channel (IG+) and the snift recovery tank GI to exhaust the air. 5).

The present invention provides a counter pressure type liquid filling machine in which one side of a filling valve provided independently of a filling liquid tank is filled with filling liquid and connected to the upper part of a distributor connected to the filling liquid tank, and the filling valve is filled with filling liquid. Since the upper end is connected to a top counter channel having an exhaust valve, and the top counter channel is connected to a tank pressure chamber formed at the upper part of the filling liquid tank, the filling liquid is not stirred and foamed as in the conventional case. Of course,
In particular, air mixed in the exhaust gas from the container is disposed of by the exhaust valve of the top counter channel to prevent it from being absorbed into the filling liquid, and even if there is a small amount of mixed gas in the filling liquid, it is prevented from accumulating in the distributor. It has one advantageous feature: the filling operation can be carried out without degrading the quality of the filling liquid.
