Abstract

<P>PROBLEM TO BE SOLVED: To accurately and simply detect running-out of a liquid. <P>SOLUTION: When a beverage container is connected, electric resistance value of a beverage fed and carried from this beverage container is detected by a sensor and a reference value rx to be used for judging the running-out of the liquid is set based on the detected value R by a reference value setting means. After the reference value rx is set, the detected value R detected by the sensor is successively compared with the reference value rx by a comparing means and when a result becomes to R≥rx, it is judged that the liquid runs out. Stopping injection and the like are performed thereby. When a new beverage container is connected, the reference value rx fitted to a new beverage is set by the reference value setting means started again through a reset means. On every connection of the beverage container, the reference value rx suitable for the new beverage is automatically set again based on kind and temperature of the beverage and running-out of the liquid is accurately detected. A complicated operation for resetting the reference value and an incidental installation for detecting temperature of the beverage can be made unnecessary. <P>COPYRIGHT: (C)2003,JPO

2. Description of the Related Art For example, in a draft beer server, when carbon dioxide gas pressurized from a carbon dioxide gas cylinder is supplied into a barrel storing beer and the pouring cock is opened in response to the operation of a pouring button, the carbon dioxide pressure is reduced. By this, beer is pressure-fed to a beer feeding pipe and is poured toward a jug or the like while being cooled through a cooling tank. Here, when the pouring operation is continued in a state where the beer in the barrel is exhausted, that is, when the liquid is exhausted, gas is pushed out together with beer, and there is a problem that beer is scattered. Therefore, a liquid shortage detection means is provided to stop the pouring operation when the liquid runs out. Specifically, an electrode-type sensor is provided in the beer feed pipe, and liquid shortage is detected from changes in the resistance value between the electrodes (generally, gas has a higher electric resistance value than liquid).

On the other hand, a sparkling beverage such as beer is likely to be in a "liquid / gas mixed state" before it runs out of liquid, and beer is likely to scatter even if it is poured out in this mixed state. It is desirable to regard it as a cut. The electric resistance value in such a "liquid / gas mixed state" takes a value between the liquid state and the gas state. Therefore, in a sparkling beverage such as beer, a value slightly higher than the electric resistance value in the liquid state is used as a reference value for determining that the liquid is exhausted.

However, the electric resistance value peculiar to a beverage such as beer to be detected depends on the type of beverage,
Since it varies depending on the beverage temperature at that time, if the reference value for determining that the liquid is running out is set to be constant, there is a risk of erroneous detection. Therefore, conventionally, it has been proposed to change the reference value each time the type of beverage to be poured changes, or to change the reference value by detecting the temperature of the beverage, but the operation is troublesome, and the beverage There is a need for a separate means for detecting the temperature of, and there is a dislike for the equipment to be complicated, and there has been a strong demand for improvement. The present invention has been completed based on the above circumstances, and an object thereof is to enable accurate and easy detection of liquid shortage.

The concrete pouring operation is performed by placing the jug J on the mounting table 12 and then pressing the pouring button on the operation board 39 to drive the mounting table 12 so that the jug J projects forward from the bottom side. He is brought to a slanting posture. Then, the operation lever 14 is tilted forward by the pouring portion drive mechanism 17, and is kept in the forward tilted position for a predetermined time after being detected by the sensor board 40. During this time, the beer receives the pressure of carbon dioxide gas and is supplied with beer. It is pressure-fed to the feed pipe 22, passes through the cold water tank 26 on the way, is cooled to an appropriate temperature, and is poured into the jug J from the beer pouring nozzle 15. When the beer pouring time elapses, the operation lever 14 is tilted rearward this time, and is kept in the same posture for a predetermined time after being detected by the sensor board 40.
The beer sent under pressure becomes fine bubbles due to the valve mechanism in the pouring unit 11, and is then poured from the foam pouring nozzle 16 to the draft beer in the jug J. When the bubble pouring time elapses, the operating lever 14 returns to the neutral position, the pouring portion 11 closes, and the mounting table 12, that is, the jug J returns to the upright posture, and one pouring is completed. Such a pouring operation is repeated.

The reference value setting means 52 is a liquid shortage sensor 42.
It functions to calculate the reference value based on the detected value from. The reference value is set to a value slightly higher than the electric resistance value of the beverage such as beer, but as described in the section of the prior art, the electric resistance value specific to the beverage such as beer is the type of the beverage, Since it varies depending on the beverage temperature at that time, if the reference value for determining that the liquid runs out is fixed and set, there is a risk of erroneous detection. Therefore, in this embodiment, when the liquid resistance sensor 42 detects the electric resistance value of a beverage such as beer that is actually poured, the reference value setting means 52 sets rx (reference value) = r (detection value) + α (constant). ) Is calculated and the reference value rx is output to the comparing means 53. At the same time, the switching means 51 switches to input the detection value of the liquid shortage sensor 42 to the comparison means 53.

As shown in FIG. 3, when comparing the electric resistance values according to the types of beverages, beer <happoshu <chuhai << water, the electric resistance value tends to increase as the proportion of water increases. , When comparing the electric resistance values according to the temperature of the beverage, it becomes high temperature <low temperature. For example, in the case of beer (A) at 30 ° C., if the reference value for liquid shortage determination is r1, the reference value is r2 which is higher than r1 for Chuhi at the same temperature. Even if the same beer (A) has a temperature of 5 ° C, the reference value is r
It is said to change to 3.

Then, in step S5, the detection value R detected by the liquid out sensor 42 is compared with the reference value rx calculated above, and if "R <rx" (step S6), the pouring out is performed. As a possible state, subsequently in step S5, the detection value R of the liquid out sensor 42 and the reference value r

7) In step S8, liquid shortage is detected. As a result, the pouring portion 11 is closed and the pouring is stopped, the warning lamp 56 is turned on and a warning that the liquid is running out is displayed, and it is urged to replace the beer barrel 20 with a new one. At the same time, the control returns to step S1, and when a beverage container such as the beer barrel 20 is newly installed, step S
4, new beverages (including the same types as before)
Is calculated and set again, and thereafter, the detection value R detected by the liquid shortage sensor 42 and the revised reference value rx are compared to determine whether or not there is liquid shortage. .

As described above, according to this embodiment, every time a beverage container such as the beer barrel 20 is newly connected, the reference value adapted to the new beverage is reset based on the type and temperature of the beverage. Therefore, the liquid outage can be accurately detected. Since the reference value is reset automatically, no special operation is required to reset the reference value. In addition, no additional equipment for detecting the temperature of the beverage is required.
