Abstract

The present invention addresses the problem of making it possible to dispense a bottled beverage into a glass without compromising the flavor. Provided is a beverage dispensing device in which, when an operation indicating that wine is to be dispensed is performed, an inert gas is guided into a wine bottle via a first flow path (CH1) and causes wine that is inside the bottle to flow from a hole in an anchor section (ANCH-k) into a tube (TUB-k). The wine rises within the tube (TUB-k) and is poured into a glass via a second flow path (CH2) and a nozzle (NZL-k). The inert gas is subsequently guided to a part between a second valve (921) in the second flow path (CH2) and the nozzle (NZL-k) via a third flow path (CH3), and the wine that remains in the part between the second valve (921) in the second flow path (CH2) and the nozzle (NZL-k) and in the nozzle (NZL-k) is discharged.

Description

Beverage dispenser

This invention relates to a technique for dispensing a beverage in a bottle into a glass.

Some beverage dispensing devices, such as servers and dispensers, hold bottles with their bottle mouths facing down, and drink the beverage that falls from the bottle mouths when the lid that closes the bottle mouths is opened. A type to pour, a type that pierces two pipes into a stopper that closes the bottle mouth of a bottle, fills the bottle with gas from one pipe, and then draws out the beverage from the other pipe and pours it into the glass There is. The latter type of beverage pouring device is suitable for dispensing fruit wine such as wine, because the starch accumulated at the bottom of the bottle is difficult to be mixed into the pouring solution.

Patent Document 1 is a document disclosing a technique related to the latter type of apparatus. The wine server described in Document 1 has a main body attached to the upper surface of a wine bottle spout, a gas conduit and a wine conduit penetrating the main body.

Is being poured into.

Japanese Patent Application Laid-Open No. 2012-197081

This type of beverage dispensing device controls the start and stop of the pouring of the beverage in the bottle into the glass by opening and closing the valve of the conduit. For this reason, in this type of beverage dispensing device, a small amount of wine that cannot be completely discharged out of the conduit is left in the conduit every time a glass of wine has been poured. If wine remains in the conduit, there is a problem in that the remaining wine is oxidized and the taste of the next poured is deteriorated.

This invention is made | formed in view of such a subject, and it aims at enabling it to dispense to a glass, without impairing the taste of a bottled beverage.

In order to solve the above problems, the present invention provides a lift part for lifting a beverage-containing bottle upward, a tube inserted into the bottle mouth of the bottle lifted by the lift part, and a seal surface against the bottle mouth. A pouring block that holds the bottle in an airtight state so that it comes into contact, and pours the beverage that rises in the tube by filling an inert gas into the glass through a nozzle into the glass, One of the two openings inside the portion in contact with the bottle mouth is used as a gas outlet, and the other opening and the opening into which the upper end of the tube is fitted is used as a beverage distribution inlet. A first flow path from the connected gas source connection port to the gas outlet, a second flow path from the beverage distribution inlet to the nozzle, the first flow path, and A third flow path connected to both of the second flow paths, a first valve provided between the first flow path and the third flow path, and the second flow path. A second valve provided in the second flow path, and a third valve provided between the second valve and the nozzle in the second flow path and the third flow path. A dispensing block; and a controller that controls opening and closing of the first valve, the second valve, and the third valve, wherein the third flow path is more than the first flow path. The controller has a narrow section, and when an instruction to inject a beverage is given, the controller closes the first valve, opens the second valve, and closes the third valve. In this way, the inert gas supplied from the inert gas source to the gas source connection port is guided into the bottle through the first flow path, and the beverage that rises in the tube is introduced into the bottle. The glass is poured into the glass through the flow path and the nozzle, and after this treatment, the first valve is opened, the second valve is closed, and the third valve is opened. Accordingly, the flow of the beverage from the tube to the second flow path is blocked, and the inert gas supplied from the inert gas source to the gas source connection port is passed through the third flow path. To the portion of the second flow path between the second valve and the nozzle, and the beverage remaining in the nozzle and the portion of the second flow path between the second valve and the nozzle Provided is a beverage dispensing device characterized by performing a process of discharging a product.

In the present invention, when an instruction for dispensing one beverage is given, the control unit supplies the inert gas supplied from the inert gas source to the gas source connection port via the first flow path. Then, the beverage is introduced into the bottle, and the beverage rising in the tube is poured into the glass through the second flow path and the nozzle. Thereafter, the control unit guides the inert gas supplied from the inert gas source to the gas source connection port via the third channel to the portion between the second valve and the nozzle in the second channel, The portion of the second flow path between the second valve and the nozzle and the beverage remaining on the nozzle are discharged. Therefore, according to the present invention, it is possible to prevent the occurrence of a situation in which a beverage remains in the nozzle every time one cup is dispensed, and the taste of the next poured is deteriorated. In the present invention, the third channel has a narrower section than the first channel. For this reason, in this invention, when the intensity | strength of the inert gas supplied to a gas source connection port from an inert gas source is the same, the pressure in the flow path of 1st flow path-> 2nd flow path-> nozzle Rather, the pressure in the flow path of the first flow path → the third flow path → the portion between the second valve and the nozzle in the second flow path → the nozzle is weaker. Therefore, according to the present invention, the beverage remaining in the nozzle can be put in the glass without being scattered around.

In FIG. 1, the control unit 79 performs three processes: a bottle loading process, a wine dispensing process, and a bottle releasing process. The contents of each process are as follows.
a1. Bottle Loading Process In this process, when an operation for placing a bottle on the placement surface of the lift unit LFT-k of the wine server SV-k and instructing the loading of the bottle is performed, the control unit 79 performs the wine server SV-k. The lift part LFT-k is raised. When the lift part LFT-k rises, the bottle mouth of the bottle on the placement surface comes into contact with the seal surface 651 of the bottle mouth holding part 6 of the wine pouring block EXB-k and moves the bottle mouth holding part 6 upward. When the bottle mouth holding part 6 moves upward, the rectangular plate part 66-1 of the bottle holding part 6 moves the snap part 118 of the micro switch 18 of the base part 1 upward, and the micro switch 18 is switched on. When the micro switch 18 is turned on, an ON signal (a signal for opening the gas valve GVL-k) is supplied from the micro switch 18 to the gas valve GVL-k. When the ON signal is supplied to the gas valve GVL-k, the gas valve GVL-k is opened.

b1. Wine Dispensing Process In this process, the control unit 79 closes the valve 827 (first valve) in the diaphragm type electromagnetic valve 8 when an operation for instructing the pouring of wine is performed. Further, the valve 921 (second valve) in the diaphragm type electromagnetic valve 9 is opened, and the valve 926 (third valve) is closed. As a result, the inert gas supplied from the gas cylinder BMB to the gas source connection port 114 is guided into the wine bottle via the first flow channel CH1 (FIG. 14), and the wine in the bottle flows into the anchor portion ANCH-k. The hole 77-m (m = 1 to 2) is pushed into the tube TUB-k. This wine rises in the tube TUB-k and is poured into the glass through the second channel CH2 (FIGS. 15A and 15B) and the nozzle NZL-k. The controller 79 opens the valve 827 (first valve) in the diaphragm type electromagnetic valve 8 after a time T1 (for example, T1 = 10 seconds) required for pouring one glass is passed. Further, the valve 921 (second valve) in the diaphragm type electromagnetic valve 9 is closed, and the valve 926 (third valve) is closed. As a result, the flow of wine from the tube TUB-k to the second channel CH2 (more specifically, the portion ahead of the valve 921 in the second channel CH2) is blocked. In addition, the inert gas supplied from the gas cylinder BMB to the gas source connection port 114 passes through the third flow path CH3 (FIGS. 16A and 16B) to the valve 921 ( The portion between the second valve) and the nozzle NZL-k (the hole 914 of the electromagnetic valve 9 → the hole 314 of the upper plate portion 3 → the annular portion 43 of the packing 4 → the hole 115 of the base portion 1 → the nozzle connection port 116 The wine remaining in the nozzle NZL-k and the portion between the valve 921 (second valve) and the nozzle NZL-k in the second channel CH2 is discharged. After the time T2 (for example, T2 = 0.5 seconds) required for discharging the residual wine has passed, the control unit 79 sets the valve 827 (first valve) in the diaphragm type electromagnetic valve 8 and the diaphragm type electromagnetic valve 9 inside. The valve 921 (second valve) and the valve 926 (third valve) are closed.

c1. Bottle Release Processing In this processing, the control unit 79 lowers the lift unit LFT-k of the wine server SV-k when an operation for instructing the removal of the bottle on the placement surface of the wine server SV-k is performed. When the lift part LFT-k is lowered, the bottle mouth holding part 6 pushed upward is moved downward, and the micro switch 18 is switched off. When the micro switch 18 is turned off, an OFF signal (a signal for closing the gas valve GVL-k) is supplied from the micro switch 18 to the gas valve GVL-k. When an OFF signal is supplied to the gas valve GVL-k, the gas valve GVL-k is closed.

Thereafter, the control unit 79 supplies the inert gas supplied from the gas cylinder BMB to the connection port 114 via the third channel CH3 between the second valve 921 and the nozzle NZL-k in the second channel CH2. Then, the wine remaining in the portion between the second valve 921 and the nozzle NZL-k and the nozzle NZL-k in the second channel CH2 is discharged. Therefore, according to the present embodiment, it is possible to prevent the occurrence of a situation in which wine is left in the nozzle each time one cup is dispensed and the taste of the next poured is deteriorated. In the present embodiment, the third channel CH3 has a narrower section (specifically, holes 316 and 317 having a diameter of 0.6 mm) than the first channel CH1 and the second channel CH2. ing. Therefore, in the present embodiment, when the strength of the inert gas supplied from the gas cylinder BMB to the connection port 114 is the same, the flow path of the first flow path CH1 → second flow path CH2 → nozzle NZL-k. In the flow path of the first flow path CH1 → the third flow path CH3 → the second flow path CH2 between the second valve 921 and the nozzle NZL-k → the nozzle NZL-k. The pressure is weaker. Therefore, according to the present embodiment, it is possible to put the remaining wine in the nozzle NZL-k into the glass without scattering the surroundings with almost no change in the time required for dispensing one cup.

Secondly, in the present embodiment, a diaphragm type electromagnetic valve 8 and a diaphragm type electromagnetic valve 9 are provided. Then, the control unit 79 supplies control signals to the diaphragm type electromagnetic valve 8 and the diaphragm type electromagnetic valve 9 so as to open and close the first valve 827, the second valve 921, and the third valve 926.

When the bottle on the bottle mounting surface comes into contact with the seal surface 651 of the bottle mouth holding portion 6 and moves the bottle mouth holding portion 6 upward, the micro switch 18 is turned on, and the micro switch 18 turned on is turned on. The gas valve GVL-k is supplied with an ON signal (a signal for opening the gas valve GVL-k). Therefore, according to the present embodiment, it is not necessary to perform a troublesome operation such as closing the gas valve GVL-k each time an empty wine bottle is removed.

Fourth, in the present embodiment, the anchor portion ANCH-k is fixed to the lower end of the tube TUB-k, and the wine is placed at a position higher than the lower surface 75D that is a surface in contact with the bottom of the bottle in the anchor portion ANCH-k. A suction hole 77-m (m = 1 to 2) is formed. Therefore, it is possible to make it difficult to mix the starch accumulated in the bottom of the bottle into the pouring liquid.

As mentioned above, although one Embodiment of this invention was described, you may add the following modifications to this embodiment.
