Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a beverage dispenser, and more particularly to a beverage dispenser that dispenses a beverage into an inclined drinking container.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, beverage dispensers that automatically pour beverages such as soft drinks and carbonated beverages into drinking containers such as paper cups, glasses, and mugs are known. The beverage dispenser is configured to open and close a dispensing valve provided at a dispensing outlet to which a beverage is supplied, thereby allowing a predetermined amount of beverage to be placed on a drinking container placed on a placing table disposed below the dispensing outlet. It is configured to dispense beverages.
[0003]
By the way, when a beverage is poured into a drinking container placed upright on a mounting table by such a beverage dispenser, the beverage is foamed uselessly in the drinking container, and the appearance of the beverage poured into the drinking container The impression may be impaired, or the beverage itself may be impaired. Also, in sparkling beverages such as beer and sparkling liquor, foam is also intentionally formed. Even in this case, the beverage supplied into the drinking container is directly on the surface of the beverage in the container. When poured, the foaming gas such as carbon dioxide contained in the beverage is excessively liberated, resulting in coarse foam (natural foaming). This natural foaming causes uneven beverage capacity, allowing natural foaming. It is required to reduce as much as possible.
[0004]
Therefore, in a beverage dispenser that is required to suppress excessive foaming, when a beverage is poured, the container is inclined by a predetermined angle from the upright position by the table tilting means on the table on which the drinking container is placed. In this way, the beverage supplied from the spout is poured out so as to flow downward along the inclined inner wall surface of the container. By pouring the beverage with the container tilted in this way, the dispensed beverage does not directly collide with the liquid level of the beverage in the container, so that shocking stirring is suppressed and While releasing can be suppressed, the drop which pours a drink can be made small, and this can also suppress release of foaming gas.
[0005]
On the other hand, in a beverage dispenser, after a predetermined amount of beverage has been supplied into the drinking container, the dispensing valve is automatically closed to stop the supply of the beverage and prevent the excessively supplied beverage from overflowing from the container. Various methods have been proposed, such as a method of detecting the liquid level of the beverage poured into the container and stopping the supply when it reaches a predetermined position (Japanese Patent No. 2933530). Yes.
[0006]
Thus, by automatically quantifying the amount of beverage dispensed, the operator of the beverage dispenser does not have to perform an operation to stop the beverage supply, so the operator is an unskilled person such as a part-time employee. However, after the operation linked to the opening of the dispensing valve, such as pressing the dispensing start button, can be kept away from the beverage dispenser. These operations can be performed in parallel, and the operation workability is improved.
[0007]
By the way, as described above, in a beverage dispenser that dispenses a beverage while tilting the drinking container, it is necessary to finally return the tilted drinking container to an upright position. This makes it easy to take out the beverage container from the beverage dispenser, and cannot supply a sufficient amount of beverage to the tilted container, and returns the container to the upright position to allow more beverage to be consumed. It is for supplying to.
[0008]
And in this type of beverage dispenser, there is a demand for automation. In this case, it is necessary to automate the operation of returning the tilted drinking container to the upright position. To meet this demand, to the tilted drinking container, A technique for controlling the table tilting means so as to return the container to an upright position is proposed (Japanese Patent No. 2933370).
[0009]
According to this technology, after a predetermined time has elapsed since the start of the supply of beverage, by returning the inclined drinking container to an upright position, it is possible to prevent the beverage from overflowing from the inclined drinking container, Supplying a sufficient amount of beverage to the drinking container returned to the upright position, and finally detecting the liquid level of the beverage in the drinking container and stopping the supply of the beverage Makes it possible to automatically supply a fixed amount of beverage.
[0010]
[Problems to be solved by the invention]
However, the technique (patent No. 2933370) for changing the inclination angle of the drinking container according to the beverage dispensing time described above is the beverage dispensing amount (cm ^Three ), Flow rate (cm ^Three / Sec) and the extraction time (sec), which is established on the assumption that the extraction flow rate is always constant.
[0011]
Therefore, according to this technique, when the dispensing flow rate changes, the beverage dispensing amount fluctuates, and the amount of beverage supplied to the container varies according to the change in the dispensing flow rate. If it is large, the timing of returning the container to the upright position is delayed, and there is a problem that the beverage overflows from the container and the supplied beverage is wasted or the container is soiled by the overflowing beverage.
[0012]
On the other hand, in an actual beverage dispenser, the beverage dispensing flow rate may fluctuate greatly depending on various factors. For example, in a beverage dispenser that supplies and distributes sparkling beverages such as beer, a beer container containing beer is placed in a cylinder. The carbon dioxide gas is pumped from the bottom and the carbon dioxide gas is dissolved in the beer, but the amount of carbon dioxide gas dissolved in the beer varies greatly depending on the temperature of the beer, so depending on the environmental temperature where the beer container is placed It is necessary to adjust the pressure of carbon dioxide. If the pressure of carbon dioxide gas changes at this time, the supply pressure of beer also fluctuates and the beer dispensing flow rate fluctuates greatly. For this reason, the above technique for changing the inclination angle of the drinking container according to the dispensing time has a problem in practice.
[0013]
The present invention has been made in view of the above circumstances, and it is possible to obtain a beverage dispenser in which the tilt angle of a drinking container is always changed in a timely manner without being influenced by the environment, thereby eliminating the waste of the beverage to be supplied. Objective.
Another object of the present invention is to obtain a beverage dispenser in which the dispensing of beverages to the drinking container is always stopped in a timely manner regardless of the environment, thereby eliminating the waste of beverages to be supplied.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the beverage dispenser of the present invention (Claim 1) is placed on a placement table disposed below the nozzle by opening and closing a dispensing valve provided in the beverage conduit. In a beverage dispenser that dispenses and supplies a predetermined amount of beverage to a drinking container, The nozzle has a beverage nozzle for dispensing beverage and a foam nozzle for dispensing foam, Beverage dispensing start means for starting the dispensing of beverage, and table tilt driving means for tilting the placing table so that the drinking container placed on the placing table is tilted from a substantially upright position to a predetermined angle position; Flow rate detecting means for detecting the flow rate to be dispensed into the beverage container; pouring valve driving means for opening and closing the pouring valve; control means for controlling the table tilt driving means and the pouring valve driving means; And the control means controls the dispensing valve by driving the dispensing valve driving means according to a signal from the beverage dispensing start means, and on the mounting table inclined to a predetermined angular position by the table inclination driving means. On the drinking container placed on Beverage Beverage is dispensed from the nozzle, the table tilt driving means is driven in accordance with the detection signal from the flow rate detection means, and the mounting table is controlled to return to a substantially upright position, and further according to the detection signal from the flow rate detection means Control the dispensing valve driving means When it is detected that foam has been poured out from the foam nozzle and foamed after stopping the dispensing of the beverage from the beverage nozzle by switching the dispensing valve, the dispensing valve is detected. Control the foam dispensing to stop It is characterized by that.
[0015]
According to the beverage dispenser according to claim 1, the control means controls the table tilting means according to a physical quantity called a flow rate that is the amount (volume) of the beverage already poured into the drinking container. Regardless of environmental fluctuations such as fluctuations in the beverage dispensing flow rate, the change timing of the tilt angle of the drinking container can be managed with higher accuracy than in the past.
In addition, in the case where the change timing of the tilt angle of the conventional drinking container is controlled by time, the dispensed flow rate of the beverage fluctuates in accordance with the environmental change, so the time of the change timing of the tilt angle is corrected based on the temperature or the like. Although it is necessary, according to the beverage dispenser according to the present invention, in order to control the table tilting means in accordance with the flow rate that is the amount of beverage dispensed itself, the calculation for performing time correction of the change timing of the tilt angle as in the prior art Is no longer necessary.
[0016]
Further, by controlling the dispensing valve driving means according to the detection signal from the flow rate detecting means and stopping the dispensing of the beverage from the nozzle, the quantity of the beverage dispensed is directly constant according to the flow rate. Therefore, the amount dispensed can be automatically quantified regardless of environmental fluctuations such as fluctuations in the beverage dispensing flow rate. Moreover, since the valve driving means is controlled in accordance with the flow rate that is the amount (volume) of the beverage to be dispensed into the drinking container, it is not necessary to make a correction according to the environmental change or the like.
[0017]
Here, the control for returning the mounting table to the substantially upright position by driving the table tilt driving unit in accordance with the detection signal from the flow rate detecting unit is, for example, the setting of the mounting table based on the flow rate at which the beverage does not overflow. Control to return to a substantially upright position is performed. In addition, when the beverage is a sparkling beverage, the dispensing flow rate may be determined in consideration of the foam so that the foam due to natural foaming generated when the beverage is poured into the drinking container does not overflow from the drinking container, On the contrary, since the foam by natural foaming impairs the flavor, the foam may be determined to overflow. This flow rate may be a flow rate obtained experimentally or empirically in advance, and can be set according to the type of beverage to be dispensed, the installation environment, and the like.
[0018]
Further, in the control to return to the substantially upright position (inclination angle within a range of about ± 10 degrees), the inclination angle may be changed small stepwise or continuously until returning to the substantially upright position. That is, at the beginning of beverage pouring, for example, an inclination angle of 45 degrees is set as a predetermined angle, and thereafter, an inclination angle of 30 degrees, an inclination angle of 15 degrees, and an inclination angle of 5 degrees (substantially upright position) are changed stepwise. Alternatively, it may be continuously returned to a substantially upright position from a predetermined angle. The inclination angle may be an angle obtained in advance by experiment or experience, and can be set according to the type of beverage to be dispensed.
[0019]
On the other hand, controlling the dispensing valve driving means according to the detection signal from the flow rate detecting means to stop the dispensing of the beverage from the nozzle means, for example, the beverage dispensing based on the flow rate at which the beverage does not overflow from the drinking container Is to stop. In the same way as for the tilt back, when the beverage is an effervescent beverage, the beverage is stopped so that bubbles caused by natural foaming generated when the beverage is poured into the drinking container do not overflow from the drinking container. In consideration of the above, the flow rate of pouring may be determined, and conversely, the foam by natural foaming impairs the flavor, so that the foam may be determined to overflow. This flow rate may also be a flow rate obtained in advance by experiment or experience, and can be set according to the type of beverage to be dispensed, the installation environment, and the like.
[0020]
In addition, it is necessary to incline the drinking container to the predetermined angle position before starting the dispensing of the beverage, but the control means controls the table tilting means to incline the drinking container to the predetermined angle position. In addition, the beverage dispensing start means is provided with a separate operation for opening the dispensing valve, a dispensing start button for performing this opening operation, etc., and depressing the dispensing start button. Detecting that an empty drinking container is placed on the placing table may be used as a trigger.
[0021]
Further, as the flow rate detecting means, a non-contact type flow sensor such as an ultrasonic type, an electromagnetic type, a Coriolis type, a contact type flow rate sensor such as an impeller type having an impeller that directly contacts a beverage, or the like is known. Various flow sensors can be applied. The drinking container includes a paper cup, a plastic cup, a glass, a cup, a mug, and the like, and also includes a pitcher for further distribution to a mug or the like, although not directly used for drinking.
[0023]
further, Since foaming is performed after the beverage is stopped to be dispensed, it is possible to add smooth and fine creamy foam, and it becomes easy to control the ratio of liquid to foam to a predetermined ratio.
[0025]
Also, If the same nozzle is used to pour out the beverage and the foam, the remaining foam will remain in the valve body or nozzle and when the beverage is poured into the next drinking container. It is first extracted into the drinking container and disrupted in the drinking container, which may induce spontaneous foaming But By having a beverage nozzle that pours out a beverage and a foam nozzle that pours out a bubble, the sull can suppress natural foaming when the beverage is poured out.
[0027]

[0029]
As shown in FIG. 2, a beer barrel 40 that is a beverage container is connected to the beer dispenser 1 shown in FIG. 1 by an external conduit, and a gas cylinder 30 that supplies carbon dioxide gas is connected to the beer barrel 40. It is connected. The inside of the beer barrel 40 is pressurized by the carbon dioxide gas supplied from the gas cylinder 30, and a part of the supplied carbon dioxide gas dissolves in the beer 41 that is a beverage accommodated in the beer barrel 40. At this time, the pressure of the carbon dioxide gas supplied from the gas cylinder 30 to the beer barrel 40 is appropriately adjusted according to the temperature of the beer 41 in the beer barrel 40 by the pressure reducing valve attached to the gas cylinder 30.
[0030]
The beer 41 accommodated in the beer barrel 40 is pressurized by the supplied carbon dioxide gas and supplied to the beer dispenser 1. The beer 41 supplied to the beer dispenser 1 passes through the inside of the conduit 22 of the beer dispenser 1, is poured out from the beer nozzle 6, and is set on the mug support 4 (mounting table 4). The beer mug 50 is poured. The conduit 22 of the beer dispenser 1 passes through the cooling water tank 23 cooled by the cooling unit 24 in a spiral spiral shape, and the beer 41 passing through the conduit 22 passes through the cooling water tank 23. In the meantime, it is configured to be cooled to a predetermined temperature.
[0031]
At the discharge end of the conduit 22, a nozzle composed of the beer nozzle 6 and the foam nozzle 2 and a substantially inverted V-shaped dispensing tap composed of the dispensing valve 20 are attached, and a jug is placed below the dispensing tap. A support base 4 is provided. The beer nozzle 6 of the pouring tap is a nozzle for pouring out the beer 41 that has passed through the conduit 22, and the foam nozzle 2 allows the beer 41 that has passed through the conduit 22 to pass through the pores formed in the inside thereof to be predetermined. It is a nozzle which pours beer 41 into a fine creamy foam shape by vigorously colliding with the wall surface.
[0032]
The extraction valve 20 is a valve for switching between the extraction of the beer 41 from the beer nozzle 6, the extraction of the foam from the foam nozzle 2, and the stop of the extraction of the beer 41 and the foam. The opening / closing switching of 20 is performed by the driving force transmitted from the dispensing valve driving unit 12.
[0033]
Reference numeral 60 denotes a flow rate sensor for detecting the flow rate of the beer 41 passing through the conduit 22. In the drawing, the flow rate sensor 60 is provided in the conduit 22 between the cooling water tank 23 and the dispensing valve 20, What is necessary is just to provide in the appropriate locations of the conduit | pipe 22 between the beer barrel 40 and the extraction | pouring valve | bulb 20, such as the conduit | pipe 22 in the beer dispenser 1 between the beer barrel 40 and the cooling water tank 23. As the flow rate sensor 60, there are various types such as a non-contact type flow rate sensor such as an ultrasonic type, an electromagnetic type and a Coriolis type, and a contact type flow rate sensor such as an impeller type having an impeller directly contacting a beverage. A flow sensor can be applied.
[0034]
The mug support 4 provided below the dispensing tap includes a substantially disc-shaped bottom plate that supports the bottom surface of the beer mug 50, and a flat abutting plate that supports a part of the peripheral surface of the beer mug 50. The hook plate is engaged with a tip receiving portion 19 of a rod 15 for inclining the mug support 4 to be described later, and is formed in an approximately L-shaped cross section as shown in FIG. Centered on the upper end portion (upper right corner portion in FIG. 1) A of the inverted L shape, a substantially upright position (angle α (0 ° ≦ α ≦ 10 °) with respect to the vertical direction) and an inclined position ( In the angle range (α ≦ θ ≦ β) with respect to the angle β (β≈60 °) with respect to the vertical direction, the beer dispenser 1 is pivotally supported by the main body case. The shaft portion on the side of the main body case that pivotally supports the upper end portion A is disposed so as to be horizontally movable rightward in the drawing.
The mug support 4 may be capable of selectively using a plurality of bottom plates having different heights according to the size of the beer mug 50 (for example, a small mug, a large mug, etc.). Moreover, it may have a bottom plate that can be raised and lowered according to the size of the beer mug 50.
[0035]
Further, the beer dispenser 1 is provided with a support table driving unit 3 as a table tilting means for tilting the beer mug 50 by rotating the mug support table 4 within the above-described angle range. More specifically, the support base drive unit 3 includes a rod 15 that presses the abutting plate of the mug support base 4 and tilts the mug support base 4, a support base drive motor 14, and a driving force of the support base drive motor 14. 15 and a link mechanism 13 that moves the rod 15 in its extending direction. A tip receiving portion 19 is provided at the tip of the rod 15.
[0036]
Furthermore, although the beer dispenser 1 is provided with the control apparatus 7, this control apparatus 7 respond | corresponds to the input from the flow sensor 60 and the extraction button 11, as shown in the control block diagram shown in FIG. The dispensing valve drive unit 12 and the support base drive unit 3 are controlled. Here, although only one dispensing button 11 is shown in FIGS. 1 and 3, a plurality of dispensing buttons (for example, a small jug dispensing button, a middle jug dispensing button, a large mug dispensing button, etc.) ) May be provided. The control device 7 receives the signal input from the dispensing button 11 that gives a signal for starting the dispensing of the beer 41 from the beer nozzle 6, switches the support base drive unit 4 to the ON state, and moves the rod 15 to the solid line position. To the position of the two-dot chain line, tilt the mug support 4 to the tilted position (θ = β), switch the pouring valve drive unit 12 to the ON state, open the pouring valve 20 and open the beer nozzle 6. The beer 41 is started to be dispensed from the beer mug 50, and the jug support 4 is tilted according to the amount of beer dispensed to the beer mug 50 detected by the flow sensor 60 (flow rate passing through the conduit 22). The support driving unit 3 is controlled so as to return to the original substantially upright position (θ = α) from the inclination angle θ = β).
[0037]
Further, the control device 7 controls the dispensing valve according to the dispensing amount to be poured into the beer mug 50 detected by the flow sensor 60 after the mug support 4 is returned to the substantially upright position (θ = α). The extraction valve drive unit 12 is controlled so that the drive unit 12 is turned off and the extraction of the beer 41 from the beer nozzle 6 is stopped.
[0038]
Next, the operation of the beer dispenser 1 of this embodiment will be described with reference to the flowchart shown in FIG. First, the conduit 22 of the beer dispenser 1 is filled with the beer 41 that has been pumped from the beer barrel 40 and cooled by the cooling water tank 23, and the supply is stopped by the closed dispensing valve 20. It has become a state.
[0039]
Here, the operator places an empty beer mug 50 on the mug support 4 that is set at the substantially upright position (inclination angle α), which is the initial state, and presses the dispensing button 11. By this operation, a signal indicating that the dispensing button 11 is in the ON state is input to the control device 7 (step 1 (S1)).
[0040]
In response to the input of this signal, the control device 7 switches the support base drive unit 3 to the ON state (S2), and the support base drive unit 3 in the ON state is rotationally driven by the support base drive motor 14. The rotation of the drive motor 14 is transmitted to the link mechanism 13 and further transmitted to the rod 15, and the rod 15 is linearly moved from the illustrated solid line position to the position of the two-dot chain line. By this movement, the tip receiver 19 provided at the tip of the rod 15 presses the back side of the abutting plate of the jug support base 4 in the substantially upright position, and the jug support base 4 has the upper end A as the center of rotation. As described above, the tilting is performed up to the tilted position (tilt angle β; indicated by the two-dot chain line) corresponding to the position after movement of the rod 15 (two-dot chain line).
[0041]
Next, the control device 7 drives the dispensing valve drive unit 12 to switch the dispensing valve 20 provided in the dispensing tap to beer dispensing from the beer nozzle 6 (S3). As a result, the beer 41 pumped through the conduit 22 is poured out from the beer nozzle 6 of the pouring tap and poured into the beer mug 50 in the inclined position. The beer 41 poured at this time collides with the inner wall surface of the beer mug 50 and flows to the bottom along the inner wall surface, but the drop from the open end of the beer nozzle 6 to the inner wall surface of the beer mug 50 is Since the drop to the bottom of the beer mug 50 when the beer mug 50 is in the substantially upright position is sufficiently small, the impact force when the beer 41 is poured is reduced, and the carbon dioxide gas dissolved in the beer 41 is reduced. It is difficult to release from the beer 41 itself, and thus the natural foaming amount in the beer mug 50 is suppressed.
[0042]
By continuing to pour out beer 41, the amount of beer 41 poured into beer mug 50 gradually increases. During this time, flow rate sensor 60 dispenses into beer mug 50. (S4), and the detected flow rate is continuously input to the control device 7. The control device 7 waits for the flow rate input from the flow rate sensor 60 to reach the predetermined flow rate (S5), and when it reaches the predetermined flow rate, switches the support base drive unit 3 to the OFF state (S6).
[0043]
Here, the flow rate is set in advance as the flow rate of the beer 41 in a range where the beer 41 poured into the beer mug 50 in the inclined position does not overflow from the beer mug 50.
[0044]
The support drive unit 3 switched to the OFF state rotates the support drive motor 14 in the direction opposite to the initial direction, and this reverse rotation operation is transmitted to the link mechanism 13 and further transmitted from the link mechanism 13 to the rod 15. Thus, the rod 15 moves to the solid line position which is the initial position. At this time, since the tip receiver 19 of the rod 15 engages with the hook 18 of the mug support 4, the jug support 4 is pulled by the rod 15 and returned from the inclined position to the original substantially upright position.
[0045]
The beer 41 is continuously poured from the beer nozzle 6, and in this substantially upright position, the newly poured beer 41 directly collides with the liquid level of the beer 41 already poured into the beer mug 50. However, the drop from the open end of the beer nozzle 6 to the liquid level of the beer 41 at this time is sufficiently smaller than the drop to the bottom of the empty beer mug 50, so that the impact is applied when the beer 41 is poured. Is small and natural foaming is suppressed.
[0046]
Even after the mug support 4 is returned to the substantially upright position, the flow rate sensor 60 continues to detect the amount poured out to the beer mug 50 (S7), and the detected flow rate continues to the control device 7. Have been entered. The control device 7 waits for the flow rate input from the flow rate sensor 60 to reach a predetermined flow rate (S8), and when it reaches the predetermined flow rate, the discharge valve drive unit 12 is switched to the OFF state and the discharge valve 20 is turned off. Is closed to stop beer pouring from the beer nozzle 6 (S9).
[0047]
Here, the predetermined flow rate is set in advance as a predetermined amount of flow to be poured into the beer mug 50, and the creamy foam that is additionally poured out from the foam nozzle 2 later is the beer mug 50. The flow rate corresponds to the liquid level of the beer 41 so as not to overflow. Specifically, the liquid surface position of the beer 41 is set so that the beer 41 and the foam divide the height of the beer mug 50 into about 7 to 3 to 8 to 2, and the liquid surface position. The flow rate of the beer 41 when the beer 41 is poured becomes the predetermined flow rate.
[0048]
Next, the main body case side shaft portion that pivotally supports the mug support 4 at the upper end A is moved to the right in the illustrated horizontal direction by a mechanism (not shown), and further in conjunction with this movement, The link mechanism 13 moves so as to maintain the tilt angle at the substantially upright position of the mug support 4, and as a result, the mug support 4 is shifted in parallel to the right in the figure while maintaining the tilt angle. The beer mug 50 placed on the support base 4 is disposed immediately below the foam nozzle 2 (S10).
[0049]
When the beer mug 50 placed on the mug support 4 moves directly below the foam nozzle 2, the control device 7 drives the dispensing valve drive unit 12 to dispense the dispensing valve 20 provided in the dispensing tap. Is switched to the dispensing of foam from the foam nozzle 2 (S11). As a result, foam is poured out from the foam nozzle 2 of the pouring tap, and creamy foam is added on the liquid surface of the beer 41 of the beer mug 50.
[0050]
The amount of creamy foam gradually increases on the liquid level in the beer mug 50 by continuing to dispense the foam, but during this time, the flow sensor 60 continues to detect the flow rate (S12). The flow rate is continuously input to the control device 7.
The control device 7 waits for the flow rate input from the flow rate sensor 60 to reach the predetermined flow rate (S13), and when it reaches the predetermined flow rate, the discharge valve drive unit 12 is switched to the OFF state and the discharge valve 20 is turned off. Is closed and the dispensing of the foam from the foam nozzle 2 is stopped (S14).
The predetermined flow rate is set experimentally or empirically in advance as the flow rate of the beer 41 in a range where the foam poured into the beer mug 50 does not overflow from the beer mug 50.
[0051]
Further, the shaft portion on the main body case side supporting the mug support 4 at the upper end A is moved in the leftward horizontal direction by a mechanism (not shown), and further in conjunction with this movement, The link mechanism 13 moves so as to maintain the tilt angle at the substantially upright position of the mug support 4, and as a result, the mug support 4 is shifted in parallel in the left direction in the figure while maintaining the tilt angle, and the beer 41 and the beer mug 50 placed on the mug support 4 after the foam is dispensed are placed at the initial standby position (S15).
[0052]
As described above, according to the beer dispenser 1 of this embodiment, the control device 7 controls the mug support 4 by the timing according to the amount of extraction extracted by the beer mug 50 detected by the flow sensor 60. In order to control the support base drive unit 3 so as to return from the inclined position to the substantially upright position, the beer 41 poured into the beer mug 50 in the inclined position is returned to the original substantially upright position before overflowing from the beer mug 50. Since the physical quantity of the flow rate which is the pouring amount (capacity) of the beer 41 poured into the beer mug 50 is used as a reference of timing for changing the tilt angle, the tilt angle of the beer mug 50 The optimal timing for changing the temperature can always be kept almost constant regardless of environmental changes. It is not necessary to change the ring, it is possible to improve the operability and reliability.
[0053]
Moreover, according to the beer dispenser 1 of this embodiment, the control device 7 controls the dispensing valve 20 at a timing according to the amount of dispensing that is detected by the flow sensor 60 and is dispensed from the beer nozzle 6 into the beer mug 50. The beer 41 poured into the beer mug 50 in the substantially upright position is stopped before the beer mug 50 overflows. Since the physical quantity of the flow rate which is the pouring amount (capacity) of the beer 41 poured into the beer mug 50 is used as a reference for the timing of stopping the pouring, the beer 41 is stopped from being dispensed. The optimal timing can be kept almost constant regardless of environmental changes, and this timing can be changed according to changes in temperature, etc. No necessity, it is possible to improve the operability and reliability.
[0054]
Furthermore, according to the beer dispenser 1 of this embodiment, the control device 7 controls the dispensing valve 20 at the timing according to the dispensing amount that is detected by the flow sensor 60 and is dispensed from the foam nozzle 2 into the beer mug 50. Since the pouring valve drive unit 12 is controlled so as to close, the pouring of the foam can be stopped before the foam poured into the beer mug 50 in the substantially upright position overflows from the beer mug 50. As a reference for the timing of stopping the foam pouring, a physical quantity called a flow rate that is the pouring amount (capacity) of the beer 41 passing through the conduit 22 itself is used, and the foam amount corresponding to the flow rate is obtained in advance through experiments or the like. It is possible to keep the optimal timing for stopping the dispensing of the bubbles, regardless of the environmental changes, and it is not necessary to change this timing due to changes in temperature, etc. The operability and reliability can be improved.
In addition, when foam is poured out from the foam nozzle 2, natural foaming may occur to some extent when the beer 41 is poured out, but occurs when the beer 41 is poured out based on the temperature, the elapsed time since the last pouring, or the like. It is also possible to predict the natural foaming amount and to correct the extraction amount extracted from the foam nozzle 2 based on the predicted natural foaming value.
[0055]
Moreover, according to this embodiment, since the flow rate sensor 60 is provided in the conduit 22, the beer running out of the beer barrel 40 and the carbon dioxide in the gas cylinder 30 can be provided without newly providing the beer running out detecting means and the carbon dioxide running out detecting means. It is also possible to detect out of gas.
That is, the flow rate per unit time is significantly different between the liquid and the gas (the gas has an overwhelmingly larger flow rate than the liquid), so that the flow rate sensor 60 pressurizes the beer 41 in the conduit 22. If it is detected that the beer has flown, it is possible to confirm that the beer barrel 40 is out of beer. Also, if the gas cylinder 30 runs out of gas, the flow rate of the beer 41 in the conduit 22 decreases until it becomes almost zero, so if the flow sensor 60 detects this state, it is confirmed that the gas cylinder 30 has run out of carbon dioxide gas. can do.
[0056]
The beverage dispenser is regularly cleaned. In this cleaning, a cleaning tank filled with cleaning water is set in place of the beer barrel 40, the inside of the cleaning tank is pressurized with carbon dioxide gas supplied from the gas cylinder 30, and the cleaning water is discharged from the nozzle through the conduit 22. In this way, the dispenser conduit 22 and the nozzle are cleaned. Conventionally, the cleaning water in the cleaning tank runs out and carbon dioxide is discharged, and blowing with carbon dioxide (gas blowing) is performed for a predetermined time. Later, it was necessary to stop the supply of carbon dioxide gas manually.
On the other hand, according to this embodiment, by providing the flow rate sensor 60 in the conduit 22, the inside of the conduit 22 is changed from a liquid to a gas, that is, the cleaning water in the cleaning tank disappears and the cleaning water is supplied into the conduit 22. It can be detected that the carbon dioxide gas to be pressurized flows. Therefore, according to this embodiment, after the flow rate sensor 60 detects the end of the washing with the washing water, the carbon dioxide gas is automatically supplied after blowing in the conduit 22 with the carbon dioxide gas for a predetermined time. It is also possible to stop automatically. Thus, at the time of washing, simply by setting the washing tank and operating the washing start button, washing with washing water and stopping of gas blowing can be performed automatically, so you can keep an eye on the beverage dispenser. Well, other work can be done in parallel.

Further, in this embodiment, the angular position at which the mug support 4 is stationary is only two positions, that is, the inclined position and the substantially upright position, but the beverage dispenser of the present invention is not limited to this form. One or more stationary tilt angle positions are set between the tilt position and the substantially upright position in the embodiment, and control is performed to change the tilt angle according to the flow rate for each tilt angle position. Alternatively, control may be performed in which the inclination angle is continuously changed according to the flow rate.

[0060]
In addition, there are a plurality of types of beer mugs 50 that can be placed on the mug support 4 such as a large mug, a medium mug, and a small mug, and when these flow rates are different from each other, the flow rate sensor 60 detects them. Depending on the amount poured into the beer mug 50, the LUT referred to by the control device 7 may be switched to one corresponding to each size mug.
[0061]
