Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to improvements in a beer metering device for pouring a fixed amount of beer into a container such as a jug.

(Prior Art) As shown in FIG. 1, the conventional beer metering dispensing device A usually includes a dispensing faucet c assembled to a column b that stands up and supports a support base a such as a counter.
Inside the spout c, a lever d provided on the outer surface of the spout c is rotated back and forth (left and right in Fig. 1) to form a lever d on the base end side of the spout c. There is a state in which the valve body 2 inserted into the valve chamber 1 is abutted against the valve seat 3 and blocks communication between the spout conduit 4a in the spout c and the valve chamber 1, and a state where the valve body 2 is inserted into the valve chamber 1. A valve mechanism e is provided which switches to the state shown in FIG. 2 in which the spouting conduit 4a and the valve chamber 1 communicate with each other apart from the valve seat 3, and furthermore, the valve body 2 of the valve mechanism e is connected to the lever d. Valve shaft 20 that moves back and forth
The valve shaft 20 is fitted so as to slide in the axial direction, and is biased forward by a spring 22 provided between the valve shaft 20 and a screw 21 provided at the rear end of the valve shaft 20. When the lever d, which is in an upright position at the part that fits with the valve body 2, is tilted backward and the valve shaft 20 is moved forward, leaving the valve body 2 in the closed position in that position, the lever d shown in FIG. As shown in FIG.
A small hole 23 is opened in the area exposed to the side,
By making the small hole 23 communicate with a communication path established inside the valve stem 20 and in the center of the screw 21 at the rear end of the valve stem 20, beer can be squirted from the small hole 23 by tilting the lever d backward. By doing so, the device is switched to a foaming device that turns into fine foam and discharges it from the spout c.

Therefore, in this conventional means, a container f such as a brewer is placed below the pouring faucet c, the lever d is pushed forward, and when the beer has been poured to a predetermined level in the container f, the lever d is returned. The foam is then poured onto the beer by pushing the lever d back.

However, with this method, when the lever d is tilted forward to pour out the beer into the container f, foam inevitably begins to be generated, and the liquid level of the beer under the foam in the container f becomes constant. There is a problem in that it is difficult to pour out a certain amount of beer so that it reaches a certain level.

The present invention has been made in order to solve this problem that occurs in conventional means, and it is possible to accurately store beer in a container as liquid beer up to a certain level with fine foam rising above it. The purpose is to provide a new means for pouring a fixed amount into

(Means for Solving the Problems) The present invention has been completed based on knowledge obtained through various studies and experiments for the above-mentioned purpose. That is, using the beer quantitative dispensing device A, first, the valve mechanism e in the dispensing faucet c is opened and beer is poured into the container f from the dispensing pipe 4 of the dispensing faucet c, and then the foaming device By opening the small hole 23 in the barrel and pouring the foam generated as the beer gushes out from the hole so as to be on top of the liquid level of the beer poured into the container f, a certain amount of dirt, etc. in the container f is released. When pouring beer, the foaming device is separated from the spouting faucet c, and the spouting faucet c does not have a foaming function, and the foaming device generates foam through the small hole 23. If the foam is placed directly into the container f from the foaming nozzle made of a thin tube without passing through the spouting pipe 4 of the spouting faucet c,
The foam produced by the foaming device and poured out no longer adheres to the inner surface of the vessel wall of the spouting faucet c, and the foam is called foam, causing foaming in the beer passing through the spouting faucet c. This eliminates the bubbles inside the spout c, and also eliminates the small gaps and irregularities that tend to generate bubbles from the inner surface of the spout c.
When the valve mechanism e inside the spouting faucet c is opened and beer is poured from the spouting pipe 4 of the spouting faucet c into the container f, the generation of foam is extremely suppressed, and the beer is kept in its liquid form. It has been found that it becomes easier to pour the beer until the surface reaches a predetermined level, and that it also becomes possible to properly arrange the foam to the level of the beer.

Then, the spouting pipe 4 of the spouting faucet c is poured into the container f using the inner wall surface of the container f, such as a pot, which is placed in a fixed position below the spouting faucet c. The pouring pipe 4 is tilted so as to protrude toward the area where the liquid level will be when the desired amount of beer is poured, so that the open end of the pouring pipe 4 is connected to the open opening at the upper end of the container f in plan view. When the beer is deviated in the direction of the inclination, the inner wall surface of the container f is deflected while the beer discharged from the tip opening of the spouting pipe 4 of the spouting faucet c is poured into the container f by a predetermined amount. The new beer collides with the surface of the beer that has already been poured into the container f, and the foam that is generated disappears, so that the beer can be poured without foam, just like pouring water. The results obtained were as follows. After dispensing a certain amount of beer into the container f in this way, in order to place the foam from the foaming nozzle on the surface of the beer in the container f, the tip opening of the foaming nozzle is By positioning it above the center of the upper opening of the upper opening rather than deviating to one side with respect to the upper opening of This is due to the effect that the group of foam can be raised above the liquid surface of the beer without flowing out from the rim of the container f.

For this reason, in the present invention, as a means for achieving the above-mentioned object, beer is filled with beer that is supported at the upper end of a column installed on a support stand and whose base end is pressurized. A first valve mechanism is provided inside the spouting faucet connected to the tank via a conduit, and the dispensing pipe on the distal end side is switched between a state in which it communicates with the conduit and a state in which it is cut off. A foaming conduit equipped with a second valve mechanism is branched, and a foaming nozzle made of a thin tube is provided at the tip of the conduit, and the tip of the foaming nozzle is connected to the spout of the spouting faucet. The dispensing pipes are arranged in parallel along the outer surface of the dispensing faucet, and the distal ends of the dispensing pipes of the dispensing faucet are extended obliquely toward a predetermined level position on the inner wall surface of the container placed at a fixed position on the upper surface of the support base. , a beer dispensing device comprising: a tip opening of the foaming nozzle being deviated to one side of the opening of the container so that the tip of the foaming nozzle faces the center of the opening of the container placed in the fixed position; This is to raise the following.

(Example) Next, an example will be described in detail with reference to the drawings. Note that the same reference numerals in the drawings as in the previous means are used for components having the same effect.

It is incorporated. Further, on the base thereof, there is provided a regulating member k serving as a ruler for placing a container f such as a pot at a predetermined position located below the spout c in front of the support column b.

The support column b is formed into a hollow tower shape and stands upright on the above-mentioned support base a, and a spout c and a foam nozzle h are mounted on the top of it on the front side (as shown in Fig. 4). It is assembled so that it protrudes from the left side. Also,
A solenoid g is installed on the upper surface of the support column b to operate a lever d connected to a valve shaft 20 of a first valve mechanism e (described later) provided inside the spout c. , is surrounded by a cover j attached to the top of the support column b so as to cover the upper half of the spout c. A switch S1 for starting the control operation of the control circuit in the control box, a cancel switch S2, and a manual control switch S3 are provided on the front side of the cover j. Also, inside the support column b, there is a conduit P connecting the spout c to the tank T, and a conduit i for the foaming nozzle h branched from the conduit P.
Also, a second valve mechanism V for bubbling is housed.

As shown in FIG. 7, the spouting faucet c has a valve chamber 1 connected and communicated with the conduit P on its internal proximal end side, and a valve body provided in the valve chamber 1 on its distal end side. 2
A piston 2 integrally formed on the front end side of the valve shaft 20 of
0a is fitted so as to be slidable back and forth, and a first valve mechanism e consisting of the aforementioned valve body 2 and a valve seat 3 with which the valve body 2 abuts against the valve chamber 1 is provided on the lower surface side. The dispensing pipe 4 is formed with a dispensing pipe 4a inside which communicates with the dispensing pipe 4a, and the dispensing pipe 4 is provided with a lever d for operating the first valve mechanism e on the distal end side, unlike the conventional dispensing pipe 4. It is the same as the faucet c, but the valve body 2 of the first valve mechanism e is fixedly provided to the valve shaft 20, and the first valve mechanism e is connected to the valve body 2 of the faucet as shown in FIG. The valve is only switched between two states: a closed state in which the valve body 2 abuts against the seat 3, and an open state in which the valve body 2 is separated from the valve seat 3 as shown in FIG. The ends are shaped into a smooth cone. and,
As a result, the spout c has a configuration in which it does not include a foaming device that spews beer from the small hole to generate foam. Also, the pouring faucet c
, the tip side of the spouting tube 4 provided on the bottom side of it is
As shown in FIG. 4, with respect to a container f such as a potter placed in a fixed position on the upper surface of the support stand a below the spout c, an inner wall surface 70 of the container f is inserted into the container f. The dispensing pipe 4 is inclined downwardly toward a portion w that is at the liquid level when filled with a specified amount of beer, and the tip opening 40 of the spouting pipe 4 is placed in the fixed position. It is arranged to be offset in the direction of the downward slope in plan view with respect to the upper end opening 71 of the container f to be placed.

The valve body 2 of the first valve mechanism e is operated to operate the first valve mechanism e.
In this example, the lever d connected to the valve shaft 20 is rotated not by manual operation but by a solenoid g operated by energization. That is, the lever d is connected to the other end side of a coil spring 51 whose one end side is connected to the body 50 of the solenoid g, to the intermediate portion in the longitudinal direction of the lever d, so that the valve shaft 20 is normally pushed forward, and the valve body 50 is connected to the lever d. 2 is kept in the closed state where it abuts against the valve seat 3, and the upper end side is connected to the operating rod 52 of the solenoid g via a connecting link 53, so that the solenoid g is activated by energization. By pushing the rod 52 forward (leftward in FIG. 5), the upper end rotates forward about the ball bearing 54, and the lower end rotates backward, thereby pushing the front end of the valve stem 20. piston 20
A is pushed backwards to separate the valve body 2 from the valve seat 3, resulting in the open state shown in Fig. 8. Also, by the control operation of the control circuit provided in the support stand a, the energization to the solenoid g is turned off. As a result, the coil spring 51 is biased to restore the valve to the closed position shown in FIG. 7. However, there are cases where the lever d is operated manually and the solenoid g is omitted.

The foaming nozzle h is formed into a thin tubular shape, and the base end of the foaming nozzle h is connected to the conduit P which is disposed within the pillar b and connected to the base end of the spouting faucet c described above. It is connected to the conduit i for the nozzle h, and its tip side is on the rear side of the spouting pipe 4, which is vertically inclined toward the bottom side of the spouting faucet c, as shown in FIG. The tip opening 90 is positioned above the center of the upper opening 71 of the container f, which is placed at a fixed position on the upper surface of the support stand a. Note that the pipe i is a normal pipe with an inner diameter of 6 mm.

A second tube installed in the middle of the conduit i for the bubble nozzle
The valve mechanism V substantially constitutes a bubbling device, and as shown in FIG. A valve chamber 63 communicating with the inlet 60 via a large-diameter passage 62 is provided in the valve box 6 provided with an outlet 61 connected to the tip side of the pipe i, and a valve chamber 63 with a diameter of 1 is provided on the bottom wall of the valve chamber 63. A passage 64 is provided which is extremely narrow to the order of millimeters, and communicates with the outlet 61 through the narrow passage 64, and a valve seat 65 is provided around the opening of the passage 64 on the valve chamber 63 side. A valve body 66 facing this is provided to be movable up and down, and a spring 67 is applied to the valve seat 6.
5, and an operating rod 69 made of an iron piece that is pulled up by the excitation of an electromagnet 68 assembled on the upper surface side of the valve body 6 is connected to the valve body 66. Then, when the valve body 66 separates from the valve seat 65 by energizing the electromagnet 68, the beer that had flowed into the valve chamber 63 from the primary side (inlet 60 side) passes through the narrow passage 64 to the secondary side ( By ejecting it to the outlet 61 side), it becomes extremely fine bubbles, and the inside of the secondary side pipe i is filled with fine bubbles up to the foam nozzle h. . In addition, in the above-mentioned embodiment, the second valve mechanism V that substantially constitutes the foaming device is turned on and off when energized.
Although this is a solenoid valve that operates an electromagnet 68 when turned off, the operating rod 69 of the valve body 66 may be moved by a manually operable member such as a lever to manually control opening and closing. .

Next, FIG. 10 is a developed wiring diagram of the control circuit of the control box installed in the support stand a, and in the same figure, S1 is the beer dispenser installed on the front of the cover j at the top of the support stand b. A start switch S2 is a cancel switch S3 provided on the front surface of the cover i in parallel with the start switch S1.
Similarly, g is a manual control switch provided on the front surface of cover j, and g is valve chamber 1 in spout c.
68 indicates an electromagnet of the second valve mechanism V for bubbling.

Further, CR1 is a relay provided in the circuit of the starting switch S1, CR1 and CR1 are relay contacts that are kept closed when the relay CR1 is turned on, and CR2 is closed when the relay contact CR1 is turned on. A relay installed in the circuit that becomes
CR2 is a relay contact that is turned on when the relay CR2 is activated and closes the circuit of the solenoid g, CR2 is a relay contact that is turned off when the relay contact CR2 is turned on, and TR1 is the aforementioned relay contact. A timer is provided in the circuit of the relay CR2, which is closed when CR1 is turned on, and TR1 is a contact provided in the circuit of the relay CR2, which is closed when the timer TR1 times out. The contact that turns on, CR3, is a relay installed in the circuit that closes when contact TR1 turns on. CR3 is the relay
A relay contact that is turned on by the operation of CR3 and closes the circuit of the electromagnet 68 of the second valve mechanism V for foaming;
TR2 is a timer provided in a circuit parallel to the circuit of the electromagnet 68, and TR2 is a contact provided in the circuit of the starting switch S1 so as to be turned on by the operation of the timer TR2.

The timer TR1 is set to a time when the amount of beer flowing out reaches a predetermined amount when the valve body 2 is opened by the operation of the solenoid g and beer is discharged from the spout c. , timer TR2
When the second valve mechanism V is opened by the operation of the electromagnet 68, the foam discharged from the foam nozzle h flows into the container f.
The amount of time required for the amount of beer poured into the container to rise above the liquid level is set.

The thus constructed embodiment apparatus operates as follows.

Place a container f such as pottery on the upper surface of the support stand a below the spout c and press the start switch S1, the relay CR1 will be energized and the relay contact CR1 will be activated.
is turned on and self-maintained, and at the same time, relay contact CR1 is turned on and solenoid g, timer TR1 and relay CR2 are activated. Then, the activation of the solenoid g opens the valve body 2, and beer is poured out from the pouring faucet c into the container f.As the activated timer TR1 times up, the excitation of the relay CR2 is cut off, and the contact CR2 is turned on. By turning off, the solenoid g returns to its original state, the valve body 2 closes, and beer discharge stops.

At this time, the timer contact TR1 is turned on at the same time, so that the electromagnet 6 of the second valve mechanism V for bubbling is turned on.
8 operates, and timer TR2 also starts operating. Then, the bubble nozzle h is activated by the operation of the second valve mechanism V.
Bubbles are discharged from the bubble, and timer contact TR2 is turned off due to the time-up of timer TR2.
The excitation of relay CR1 is cut off, and one cycle of beer pouring comes to an end.

Also, during this process, cancel switch S2
If you press , the excitation of relay CR1 will be cut off,
The state is the same as the time up of timer TR2, and beer dispensing stops.

Also, if you press the manual control switch S3, the circuit of the solenoid g will be closed via the normally closed contact CR2 for the time you press it, and the valve body 2 will open and start dispensing beer. .

Therefore, each time the switch S1 is pressed, the amount of beer accumulated by the time and flow rate set in the timer TR1 is weighed out into the container f, and foam is added to the surface of the beer. The foam discharged from the nozzle h will be piled up for the time set in the timer TR2.

In this way, when pouring a certain amount of beer into the container f placed at a fixed position on the base surface of the support stand a, first, the first valve mechanism e is opened and the pouring faucet c is turned off. In the first step of discharging beer from the pipe 4, the spout c is separated from the second valve mechanism V and the foaming nozzle h, which is a foaming device, so that there is no air inside the spout c. Due to the phenomenon that bubbles call bubbles, the adhesion of bubbles generated by the bubble generating device, which causes bubbles, is eliminated, and the springs 22 and screws 2 of conventional means, which cause small bubbles, are eliminated.
Due to the absence of the first beer, the beer discharged from the pouring pipe 4 has almost no foam. At this time, if the beer is sufficiently cooled by the cooler 80, the beer will be discharged without foaming.

When the non-foaming beer discharged from the spouting pipe 4 is poured into the container f placed at a predetermined position, the beer discharged from the spouting pipe 4 is poured into the container f. This is because beer collides with a portion of the wall surface 70 that reaches a specified level, which is the liquid level when a predetermined amount of beer is poured into the container f, and the beer flows along the inner wall surface 70 and fills the container f. , until a predetermined amount of beer is poured into the container f without colliding with the surface of the beer already poured into the container f. As a result, the foaming that occurs when beer is poured onto the liquid surface of the beer is properly suppressed, and a specified amount of beer is poured into the container f with the liquid level at a specified level without foaming. Become poured into it.

In addition, the process of stacking the foam discharged from the foaming nozzle h, which is performed after this state is reached, is performed at the center of the upper end opening 71 of the container f where the tip opening 40 of the spouting pipe 4 is displaced. From the tip opening 90 of the foaming nozzle h located above the container, foam is discharged in the form of a mass of extremely fine creamy foam, which falls onto the surface of the beer in the container f and gradually spreads in all directions. Since the foam swells and becomes able to be placed in the opening of the container f, the foam can be placed in the container without causing the mistake of causing the foam to overflow from the rim of the container f.

(Effects of the Invention) As explained above, the beer quantitative dispensing device according to the present invention has a dispensing faucet c provided with the first valve mechanism e.
A conduit i for foaming, which is equipped with a second valve mechanism V, is branched from the conduit P that leads beer to the
A foaming nozzle h made of a thin tube is provided on the tip side of the foaming nozzle h, and the tip side of the foaming nozzle h is arranged in parallel along the outer surface of the spouting pipe 4 of the spouting faucet c. The tip end side of the tube 4 is extended obliquely toward a specified level position on the inner wall surface of the container f placed at a fixed position on the upper surface of the support base a, and the tip opening 4 is opened.
0 is shifted to one side of the opening of the container f, and the tip of the bubbling nozzle h is made to face the center of the opening of the container f placed in the fixed position.
The pre-stage operation of pouring the beer into the container f placed in a predetermined position without foaming, and the operation of placing beer foam on the liquid surface of the beer poured into the container f are performed by the dispensing faucet c and the foaming nozzle. h and the inner surface of the vessel wall of the dispensing faucet c is cleaned with a narrow gap in which there is no adhesion of bubbles that can cause foaming, and where foaming can occur. Since there are no small protrusions or small protrusions, foaming can be prevented when beer is poured out from the spout c.

Since the pouring faucet c discharges the beer poured out from the pouring pipe 4 toward the inner surface of the container wall of the container f, the beer collides with the surface of the beer already poured into the container f, causing foaming. No more tightening. In addition, the foaming nozzle h drops a mass of fine bubbles into the center of the open mouth of the container f, so that the foam can be placed without causing the mistake of overflowing the foam to the outside of the container f. I'll be able to go.

Therefore, the beer in the first stage without foaming can be poured into the container f placed at a predetermined position from the spout pipe 4 of the faucet c without foaming, and the beer in the second stage can be poured without foaming. The foam can now be placed on the liquid surface without causing the foam to flow out from the rim of the container.
Beer can be accurately poured into a container f in a certain amount at a time, with the beer being liquid up to a certain level and fine foam rising above it.
