<Overall structure>
FIG. 1 is an overall perspective view showing a carbonated content adjustment type beverage providing device (1) (hereinafter, abbreviated as device (1)) according to a first embodiment of the present invention.
The device (1) includes at least a main body section (4) as shown in FIG. 1, a piping machine section shown in FIG. 2, and a control section (100) shown in FIG. The main body part (4) includes a beverage container setting part (5) for placing a beverage container, an input part (20) for various information, a designation part (19) and a display part (60) such as various display devices. In the configuration shown in FIG. 1, a carbonated beverage of a predetermined type and a predetermined concentration is supplied to the beverage container (3) like a tap of a water supply by operating a discharge opening/closing valve (54) provided near the discharge opening (51). It is possible to configure a carbonated beverage supply device capable of supplying.
The beverage container (3) may provide carbonated beverages in containers such as wine glasses, cups, jugs, tumblers and the like.

The device (1) is provided with one outlet (51) for the plurality of beverage tanks (50), and the carbonated beverage can be provided from the outlet (51) to the beverage container (3).
In a store that sells carbonated drinks, the main body part (4) and the discharge port (51) can be installed at positions separated by piping.
The device (1) comprises two or more beverage tanks (50) in which carbonated beverages are stored. The beverage tanks (50) are detachably attached to the device (1) and can be replaced with different beverage tanks (50).

<Structure of piping machinery section>
FIG. 2 is a schematic view showing a piping mechanical part of the device (1) according to the first embodiment of the present invention.
The piping of the piping machine section includes a carbon dioxide gas supply path (11) to which carbon dioxide gas is supplied from a carbon dioxide gas cylinder (12) and a beverage supply path (53) to which carbonated drinks are supplied from each beverage tank (50). ) Is roughly divided into two.
The beverage supply passage (53) is provided with a beverage opening/closing valve (22) for each beverage tank (50), and a common passage (52) is provided for the supply passage having the plurality of beverage opening/closing valves (22). Is provided.
Further, there is only one pipeline on the downstream side of the discharge port (51) side from the connection position (55), and the flow rate detection sensor (30) is provided in the pipeline. Discharge of the carbonated beverage having passed through the flow rate detection sensor (30) is operated by the discharge port opening/closing valve (54).
The outlet opening/closing valve (54) is a valve that is configured by a cock or the like and that is operated by an operator. However, it may be a valve that is automatically operated by the control unit (100).

When the beverage opening/closing valve (22) of each beverage tank (50) is opened, the pressure of the carbon dioxide gas applied to the beverage tank (50) exerts a water pressure on the discharge port (51) in the direction of pushing the carbonated beverage. The beverage supply paths (53) of the beverage tanks (50) are connected in parallel, and the beverage opening/closing valves (22) are located closer to the beverage tank (50) than the connection position (55). For example, by opening the open/close valve of one beverage tank (50) and closing the open/close valves of all other beverage tanks (50), only carbonated beverages having a predetermined carbonate concentration can be supplied.
It is preferable that the two or more beverage tanks (50) respectively contain different types of carbonated beverages, but a plurality of beverage tanks (50) containing the same type of carbonated beverage may be present at the same time. That is, it is possible to previously provide a plurality of beverage tanks (50) that store carbonated beverages that are popular and are provided many times.

The flow rate detecting means (30) includes a positive displacement flow meter, a turbine flow meter, a mass flow meter, a vortex flow meter, an ultrasonic flow meter, an electromagnetic flow meter, a diaphragm flow meter, an optical flow meter, and the like. A type that can be measured by directly contacting the carbonated drink can be used, but a sensor that is not in contact with the carbonated drink is more preferable. Even if a flow sensor of the type that comes into contact with a fluid is sufficient to measure the flow rate, in the case of a sensor of the type that comes into contact with the sensor, the fluid adheres to the sensor part, so droplets may remain in that part. Therefore, it may become a source of bacteria and the like. Further, it is necessary to maintain the cleanliness by regularly cleaning the beverage supply path and the like, but in the case of the contact type, there is a risk that the cleaning may be hindered because some terminal or the like projects in the pipe. As the contact type, it is preferable that there is no terminal or the like in the pipe and the structure does not interfere with cleaning or the like.
Some of the flow rate detecting means (30) that are not in contact with the carbonated beverage use ultrasonic waves, but a non-contact laser sensor which is one of optical flow meters can also be used.
A sensor that uses ultrasonic waves utilizes the fact that ultrasonic waves that flow in a fluid travel slowly when countering the flow and travel quickly when riding on the flow. There are various methods, such as a Doppler method and a sing-around method, in which a receiver is installed and the time difference of ultrasonic waves when transmitting alternately is converted as a flow rate.
As the non-contact laser sensor, there is an optical sensor that measures the flow rate by analyzing the reflected light when the laser is irradiated. In this type of sensor, it is known that the frequency of light reflected by a moving object changes according to the speed of the object (laser Doppler phenomenon). The optical non-contact laser sensor measures the flow velocity of a fluid by analyzing the frequency change of emitted light and reflected light.

When an optical system is adopted as the non-contact laser sensor, since it is light, it can respond at high speed to a fluid (that is, a carbonated drink) and can measure the flow rate with high accuracy.
Furthermore, if a non-contact laser sensor is used instead of the contact type, not only the flow rate can be measured by analyzing the reflected light intensity, but also bubbles and foreign substances in carbonated drinks and the concentration change of carbonated drinks can be detected. is there. Therefore, the quality control of the carbonated drinks provided is facilitated.
Since the device (1) is provided with one flow rate detecting means (30) arranged between the discharge port (51) and the common path (52), the measurement error of each beverage tank derived from the measuring device is eliminated. Can be reduced.

The second function is a function of pushing out the carbonated beverage in the beverage tank (50) by the supplied carbon dioxide gas pressure and providing it from the discharge port (51).

  Moreover, in this embodiment, the gas opening/closing valve (21) for each beverage tank (50) is provided on the beverage tank (50) side of the connection position (32) of the carbon dioxide gas cylinder (12) to each beverage tank (50 ). ) Is provided and the pressure of the gas pressure adjusting unit (10) is applied to make the gas pressure on the downstream side of each gas on-off valve (21) different from one another, thereby constituting the carbon dioxide concentration adjusting means (110). is there. With this configuration, the gas pressure can be adjusted by one gas pressure adjusting unit (10) for the plurality of beverage tanks (50).

A carbon dioxide gas cylinder (12) filled with carbon dioxide gas is detachably connected to the beverage tank (50) via a carbon dioxide gas supply passage (11). The carbon dioxide gas cylinder (12) can be replaced with another carbon dioxide gas cylinder (12) when the filled carbon dioxide gas becomes empty.

(3) In a predetermined carbonated beverage, various methods are conceivable as the configuration produced by adjusting the mixing ratio. As described above, it is easy to manufacture from the two beverage tanks (50) having the closest carbonate concentration, but each carbonate concentration is based on the control program provided in advance in the control unit (100) or the operator's input. It is also possible to manufacture a beverage having a predetermined carbonic acid concentration in consideration of information such as the remaining amount of the beverage tank maintained at. Further, the number of the beverage tanks (50) that realizes the predetermined mixing ratio is not limited to two, and it is also possible to make a plurality of three or more.
Further, in the gas supply path and the like, the structure is such that one gas tank supplies gas to the beverage tank in parallel, but it does not necessarily have to be in parallel, for example, carbon dioxide gas is supplied from two or more gas tanks to different beverage tanks. It may be a structure that does. In that case, the gas supply paths from the respective gas tanks may not be in parallel, but it is substantially the same as controlling in parallel by managing the supply amount and the like by the control unit (100). Furthermore, after branching from one gas tank at the connection position (32), instead of directly connecting to the beverage tank (50) via the gas on-off valve (21), the beverage tank (via the other device, etc. 50) may be connected.

  The present invention comprises a plurality of carbonated beverage tanks, carbon dioxide concentration adjusting means for adjusting the carbon dioxide concentration of the beverage tank to a plurality by changing the pressure of the carbon dioxide gas supplied from the carbon dioxide gas cylinder to the beverage tank, the carbon dioxide It is equipped with a mixing ratio setting means for adjusting the mixing ratio from a plurality of beverage tanks with different concentrations, and since it is configured to adjust the carbonate concentration by mixing beverages with different carbonate concentrations, it is possible to use multiple types of carbonates. It is possible to provide a device that can easily provide a concentrated beverage. Further, since it is a useful invention that may meet the needs of a wide variety of customers, it is obvious that it has industrial applicability.
