Abstract

The present invention is a system for the convenience of quality maintenance and management in selling a variety of draft beer so that customers can drink draft beer according to a desired amount in a self-styled manner. In an environment where many types of draft beer that have not been experienced before are sold, customers can drink a draft beer that suits their taste by discharging a small amount of draft beer and tasting it. The quality of draft beer can be maintained for a long time by preventing economical loss and environmental pollution of the beer, and the so-called overcarbonation phenomenon in draft beer by carbon dioxide for extraction is prevented, and when pouring draft beer, excessive foaming occurs when fertilizing with customers. It can prevent the formation of draft beer and the discarding of draft beer into bubbles.When draft beer in the draft beer barrel is exhausted, a trace amount of draft beer remaining on the bottom is bubbled and spewed out, preventing contamination of the surrounding area and abnormal measurement of the flow meter, and when replacing the draft beer barrel It allows normal draft beer to be discharged without performing a separate foam removal operation on the device, and employees and customers can easily recognize it when there is no measurement of the flow meter even though several tags have been performed. This is a draft beer dispensing system that allows the registration of the RF card to be automatically canceled when the calculation is completed in order to prevent reuse in case of loss and theft, and convenience of management, and the type and unit price can be entered and changed by the familiar POS system.

Description

Draft beet dispensing system

The present invention relates to a draft beer dispensing system, and more specifically, a customer can self-drink draft beer according to a cup, and can be discharged in an amount desired by the customer without being discharged to a predetermined sales unit. Considering that a variety of draft beer is sold, it is possible to taste draft beer in a small amount and to drink it in a small amount, so that you can drink a draft beer that does not suit your taste or throw it away without being able to drink it again due to the set sales amount. It relates to a draft beer dispensing system that can prevent economic loss and environmental pollution by eliminating this.

In addition, the present invention prevents the phenomenon of overcarbonic acid, which causes deterioration of the taste and excessive foaming due to the increase of the dissolved carbonic acid of the draft beer due to the excessively dissolved carbon dioxide for extraction supplied to the draft beer barrel. Draft beer that maintains the flavor and sells many types of draft beer, which lengthens the replacement cycle of draft beer, or reduces excessive foaming when inexperienced customers self-extract draft beer by maintaining the proper dissolved carbonic acid for draft beer. It relates to an exhaust system.

In addition, in the present invention, when the draft beer discharge tab is lowered while the draft beer in the draft beer barrel is exhausted, a trace amount of draft beer remaining on the bottom of the draft beer barrel is mixed with carbon dioxide gas for extraction to form bubbles, thereby preventing contamination of the surroundings. In addition, it relates to a draft beer dispensing system in which draft beer is always kept filled in the draft beer dispensing pipe, so that the draft beer can be discharged without preparing the same as at the beginning of business after replacing the draft beer container.

In addition, the present invention tags the RF tag to the tag reader provided at the counter when the customer enters, so that the table is designated and registered on the POS terminal, and the registration is automatically terminated when the calculation is completed in the POS terminal when the customer leaves. The present invention relates to a draft beer dispensing system that makes it easier to manage RF tags without resetting the device, and prevents deliberate reuse by allowing automatic reset by calculation even when the RF tag is lost or stolen.

In addition, the present invention relates to a draft beer dispensing system that allows the owner and the employee to input and change the unit price of the draft beer in a familiar POS system so that the owner or employee can easily use it.

In addition, the present invention makes it easy for the staff to find it when the draft beer in the draft beer barrel is exhausted and replace it with a new draft beer barrel, and the customer stops the sale (sold out) processing to prevent unnecessary tags on the exhausted draft beer tap. It relates to a draft beer discharge system.

Draft beer dispensing systems are provided in restaurants, taverns or beer specialty stores (hereinafter referred to as'stores') that handle draft beer.

As shown in FIG. 7, the conventional draft beer discharge system includes a draft beer barrel 10 in which draft beer is stored; A carbon dioxide gas container 20 filled with an extraction carbon dioxide gas for injection into the draft beer container 10; An extraction carbon dioxide gas injection means (30) for injecting the carbon dioxide gas for extraction from the carbon dioxide gas cylinder (20) into the draft beer barrel (10); It is configured to include; draft beer discharging means 40 for discharging the draft beer in the draft beer barrel 10.

The draft beer barrel 10 has a carbon dioxide gas injection valve 11 provided at an upper end, and is installed in the draft beer barrel 10, the upper end is connected to the carbon dioxide gas injection valve 11, and the lower end is the draft beer barrel 10 It includes a carbon dioxide gas inner injection pipe 13 located between the upper end of the draft beer barrel 10 and the maximum height of the draft beer.

The draft beer barrel 10 is installed in the draft beer barrel opening/closing valve 14 provided at the top, the draft beer barrel 10, and the top is connected to the draft beer barrel opening/closing valve 14, and the lower end of the draft beer barrel 10 It includes an internal discharge pipe 17 located close to the floor.

The carbon dioxide gas cylinder 20 includes a carbon dioxide gas cylinder opening/closing valve 21 provided at an upper end.

The carbon dioxide gas injection valve 11 and the draft beer barrel opening/closing valve 14 are closed when storing and transporting the draft beer barrel 10, before and after the start of business, to prevent leakage of draft beer, and start business. When opened, a conventional one is used to allow the injection of carbon dioxide gas and the discharge of draft beer.

The carbon dioxide gas cylinder opening/closing valve 21 is closed when storing and transporting the carbon dioxide gas cylinder 20 and before and after the start of the carbon dioxide gas business to prevent leakage of carbon dioxide gas, and is opened to prevent carbon dioxide gas from leaking. Conventional ones are used that allow the injection of

The carbon dioxide gas injection valve 11, the draft beer barrel opening/closing valve 14, and the carbon dioxide gas barrel opening/closing valve 21 are configured as manual valves provided with handles 12, 15, and 22, respectively. The handles 12, 15, 22 may be configured as a lever type or a circular handle type.

A pressure gauge 23 is connected to the carbon dioxide gas cylinder opening/closing valve 21.

The carbon dioxide gas injection means 30 includes a carbon dioxide gas external injection pipe 31 connected between the carbon dioxide gas supply valve 21 and the carbon dioxide gas injection valve 11.

The draft beer discharge means 40 includes a draft beer external discharge pipe 41 having a lower end connected to the draft beer barrel opening/closing valve 14 and connected to an upper portion, and a draft beer discharge tab installed at the end of the draft beer external discharge pipe 41 ( 42).

The draft beer discharge tab 42 is a conventional one including a tap lever 43 and a discharge port 44 is used.

In such a conventional draft beer discharge system, when the store starts business, the employee checks the remaining amount of draft beer in the draft beer barrel 10 and the remaining amount and pressure of the carbon dioxide gas for extraction in the carbon dioxide gas barrel 20, and opens the carbon dioxide gas cylinder opening and closing valve 21. By opening, the carbon dioxide gas for extraction in the carbon dioxide gas cylinder 20 is injected into the draft beer barrel 10 through the carbon dioxide gas external inlet pipe 31, and the carbon dioxide gas for extraction injected into the draft beer barrel 10 is the draft beer barrel 10 ) While forming a carbon dioxide layer for extraction on the surface of the draft beer inside, while maintaining the pressure on the surface of the draft beer, lower the tap lever 43 of the draft beer discharge tab 42 to test discharge, and then release the tap lever 43. Raise to close the draft beer discharge tab 42.

In this state, the draft beer discharge tab 42 is closed, the upper end of the draft beer discharge pipe 41 is closed by the draft beer discharge tab 42, and the lower end is immersed in the draft beer in the draft beer barrel 10, so the draft beer internal discharge pipe ( 17) and the draft beer external discharge pipe 41 is maintained in a state filled with draft beer.

When the tap lever 43 of the draft beer discharge tab 42 is lowered while the lower end of the draft beer inner discharge pipe 17 is sufficiently immersed in the draft beer in the draft beer barrel 10, the draft beer discharge tab 42 is opened and the draft beer barrel 10 The draft beer inside rises through the draft beer internal discharge pipe 17, the draft beer barrel opening/closing valve 11, and the draft beer external discharge pipe 41 and is discharged through the discharge port 44 of the draft beer discharge tab 42.

When the draft beer in the draft beer barrel 10 is exhausted and the lower end of the draft beer inner discharge pipe 17 is not sufficiently immersed in the draft beer, the carbon dioxide layer for extraction is formed up to the bottom of the draft beer barrel 10, so the draft beer discharge tab 42 When the tap lever 43 of is lowered, the draft beer discharge tab 42 is opened, and the carbon dioxide gas for extraction in the draft beer barrel 10 opens the draft beer internal discharge pipe 17, the draft beer barrel opening and closing valve 11, and the draft beer external discharge pipe 41. It rises through and is ejected through the discharge port 44 of the draft beer discharge tab 42.

At this time, a trace amount of draft beer remaining on the bottom of the draft beer barrel 10 is mixed with carbon dioxide gas for extraction and is ejected to form bubbles and pollutes the surroundings, as well as measuring the amount of draft beer discharged using a flow meter and operating in a self-styled manner. In the case of the system, the flow meter recognizes that a much larger amount than the actual flow rate has been discharged due to the ejection of carbon dioxide gas, and there is a problem that an excessively large amount is charged than the actual amount used. In addition, there is a dispute with the customer as an excessive amount is charged than the actual amount used.

In order to solve this problem, a first draft beer external discharge pipe 41a connected to the draft beer barrel opening and closing valve 11 and a second draft beer external discharge pipe connected to the draft beer discharge tab 42 Consisting of (41b), a carbon dioxide gas jet prevention means 50 is provided between the upper end of the first draft beer external discharge pipe 41a and the lower end of the second draft beer external discharge pipe 41b.

The carbon dioxide gas ejection preventing means 50 includes a chamber 51 connected between the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b, and the chamber 51 to be able to float and settle. It is configured to include a knitting (52) to be installed.

The chamber 51 has a lower end connected to the upper end of the first draft beer external discharge pipe 41a, and a side surface thereof connected to the second draft beer external discharge pipe 41b.

The knitting device 52 allows the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b to communicate through the chamber 51 when injured, and when settled, the first draft beer external discharge pipe 41a and The second draft beer external discharge pipe (41b) is configured to be blocked.

When the lower end of the draft beer inner discharge pipe 17 is sufficiently immersed in the draft beer in the draft beer barrel 10, the carbon dioxide gas ejection preventing means 50 includes a first draft beer external discharge pipe 41a and a chamber 51, and a second draft beer external discharge pipe. Draft beer is maintained in a state filled in (41b), and accordingly, the knitting device 52 is injured and the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b are maintained in a state in which the draft beer is discharged. When the draft beer in the draft beer barrel 10 is exhausted and the lower end of the draft beer internal discharge pipe 17 is not sufficiently immersed in the draft beer, the knitting 52 loses its buoyancy and descends, and the first draft beer external discharge pipe 41a and the second Blocking the draft beer external discharge pipe 41b prevents the extraction of carbon dioxide gas for extraction as described above.

However, even if the lower end of the draft beer inner discharge pipe 17 is sufficiently immersed in the draft beer in the draft beer barrel 10, the carbon dioxide gas pressure in the carbon dioxide gas barrel 20 decreases, so that the draft beer in the draft beer barrel 10 When the pressure of the carbon dioxide gas for extraction applied to the surface is lower than the head pressure of the draft beer filled in the draft beer internal discharge pipe 17, the first draft beer external discharge pipe 41a, the chamber 51 and the second draft beer external discharge pipe 41b, draft beer Draft beer filled in the internal discharge pipe 17, the first draft beer external discharge pipe 41a, the chamber 51, and the second draft beer external discharge pipe 41b flows back into the draft beer barrel 10, and the knitting 52 Draft beer in the draft beer barrel 10 even if the pressure of the carbon dioxide gas for extraction in the draft beer barrel 10 returns to normal by blocking the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b by falling after loss of buoyancy. Is not discharged.

In this state, in order to allow the draft beer in the draft beer barrel 10 to be discharged, the knitting 52 of the carbon dioxide gas ejection prevention means 50 is manually restored (raised), and the same preparation work as at the beginning of the first business is performed. There is a hassle to do.

Meanwhile, in general, the dissolved carbon dioxide gas pressure of draft beer to maintain the unique flavor of draft beer is 0.5 bar to 1 bar, depending on the type of draft beer, and the carbon dioxide gas pressure for extraction injected to extract draft beer in the draft beer barrel is the environment in which draft beer is discharged ( It is about 0.8~4bar depending on the refrigerator type or cooler type).

Stores employing the prior art and the prior art 1 and 2 generally open the carbon dioxide gas cylinder opening/closing valve 21 and the carbon dioxide gas injection valve 11 throughout business hours, and the carbon dioxide gas pressure for extraction on the surface of the draft beer in the draft beer barrel Since this is maintained in the state of being applied, the carbon dioxide gas for extraction continuously melts into the draft beer in the draft beer barrel 10, resulting in an overcarbonation phenomenon in which the dissolved carbonic acid of the draft beer increases, and thus the draft beer loses its own flavor. In addition, there is a problem that excessive foaming occurs when draft beer is discharged.

In order to suppress such overcarbonation, the carbon dioxide gas cylinder opening/closing valve 21 or the carbon dioxide gas injection valve 11 is closed while draft beer is not discharged, and the carbon dioxide gas cylinder opening/closing valve 21 or carbon dioxide gas injection only when the draft beer is discharged. A method of opening the valve 11 may be used, but in this case, there is a problem of being very cumbersome because it is necessary to open and close the carbon dioxide gas cylinder opening/closing valve 21 or the carbon dioxide gas injection valve 11 from time to time, and in general, a single draft beer Although a discharge system is installed, the draft beer specialty store that sells tens to hundreds of types of draft beer has to open and close tens to hundreds of carbon dioxide gas cylinder opening and closing valves 21 and carbon dioxide gas injection valves 11, so this method can be practically applied. none.

The draft beer discharging system described above is made by manual operation, and the draft beer container 10, the carbon dioxide gas container 20, and the draft beer discharging tab 42 are installed in the kitchen or counter of the store so that the employee can use the draft beer cup according to the customer's order. The draft beer discharged through the outlet 44 is placed in the lower portion of the outlet 44 and the tap lever 43 is lowered to provide the draft beer to the customer.

Customers who enter the store to which such a conventional draft beer dispensing system is applied immediately go to the table, and in order to order draft beer, wait for the employee to come to the table or press the call bell to call the employee.

In addition, if there are many customers and if the order is large, the employee is confused, and a draft beer other than the ordered draft beer comes out, which will offend the customer as well as the inconvenience of returning the wrong menu and waiting for the order menu to come out. Will suffer.

In addition, in a self-service store (hereinafter referred to as a'self-service store'), there is a hassle in that the customer has to go to the cash register to place an order and pay, pick up the draft beer according to the cup and return to the table. Problems in general stores also arise.

As a prior art that can solve these problems, Korean Patent Registration No. 10-0932034 (20)09.12.07. Registration) "Oaktong Draft Beer Supply Rate Calculation System" (hereinafter,'Prior Technology') is a draft beer discharging coke installed in an oak barrel when drinking draft beer on the spot, receiving the flow rate data detected by the flow sensor and being discharged. Disclosed is a technology that displays the amount of beer or the amount of draft beer accumulated so far to the consumer, and at the same time provides it to a POS terminal through a communication means for automatic calculation to provide convenience in use.

However, the prior art is to open the draft beer discharging cock attached to the oak barrel installed on each table to discharge draft beer.Since an oak barrel, a carbon dioxide gas container, a draft beer discharging cock, and a display panel must be installed for each table, one or two types of beer It may be applicable to the case of handling, but there is a limit in its application to a beer specialty store that handles a wide variety of beers from dozens to hundreds of types or more.

As a prior art that can solve the problems of prior art 1, Korean Patent No. 1511293 (20) 15.04.06. Registration) "Self-selling beer sales device and method" (hereinafter,'prior art 2') is installed with outlets, tag readers, and tag readers installed adjacent to each liquor or beverage, and when contacting the RF tag with the tag reader, liquor or beverage A display unit that displays the amount and cumulative amount of the product and selects the amount at the same time, a valve that regulates beverage or alcohol discharged through the outlet, a flow meter that measures the amount of beverage or alcohol discharged, and discharges a selected amount of beverage or alcohol Disclosed is a technology related to an apparatus and method for self-selling beer including a microcomputer so as to be possible.

Recently, as many small breweries have been created and the craze of draft draft beer has blown around the world, the popularity of beer specialty stores that handle a variety of beers is on the rise.There are many types of beer that customers have not experienced at these beer specialty stores, so the first beer to taste. There is a demand for the pleasure of tasting and choosing a beer that suits your taste.

However, in the prior art 2, since the amount of beer that can be discharged is determined in advance by sales units such as large, medium, small or 300cc, 500cc, 1000cc, the amount of sip that can be tasted, for example, about 10cc to 50cc, can be discharged. There is no choice but to select the amount of sales unit from the beginning, and as a number of beers with various flavors and aromas have been produced recently, if a customer discharges a beer that does not suit their taste, it is forced to drink the discharged amount or leave it without drinking. As a result, it not only causes economic loss, but also causes environmental pollution as beer is discharged to the effluent system.

In addition, prior art 2, when the customer exits, touches the RF tag back to the tag reader provided on the counter to display the type, price, and accumulated amount of beverages or alcohol on the monitor, and after calculating the accumulated amount, the RF tag ID The stored contents are reset so that the RF tag can be reused. For calculation, the process of contacting the RF tag to the tag reader provided in the counter again, and the process of resetting by using the keypad by looking at the monitor are required. There is a problem that the work of the employee increases.

In addition, in the prior art 1 and 2 above, since the carbon dioxide gas pressure for extraction is applied to the surface of the draft beer in the draft beer barrel from the beginning of the business to the end of the business, the carbon dioxide gas for extraction melts into the draft beer in the draft beer barrel and generates overcarbonic acid, resulting in the natural flavor of the draft beer. There is a problem in that when the draft beer is discharged, excessive bubbles are generated.

The draft beer discharge tab 42 is a conventional one including a tap lever 43 and a discharge port 44 is used.

Since the draft beer discharging system according to the present embodiment discharges the draft beer in the same manner as in the prior art described above, a detailed description thereof will be omitted.

The draft beer discharging system according to the present embodiment further includes an overcarbonation prevention means 100 for preventing an increase in carbon dioxide gas pressure inherent in the draft beer by melting the carbon dioxide gas for extraction injected into the draft beer barrel 10 into the draft beer.

The over-carbonic acid preventing means (100) is installed in the middle of the carbon dioxide gas external injection pipe (31) and closed when power is cut off, and an electronic carbon dioxide gas opening and closing valve (110) that is opened when power is applied; A flow meter 120 installed in the middle of the draft beer external discharge pipe 41; An electromagnetic contactor 130 for turning on/off power applied to the electronic carbon dioxide gas opening/closing valve 110 according to a flow measurement signal of the flow meter 120; And an initial carbon dioxide gas injection switch 140 connected in parallel with the electromagnetic contactor 130 to turn on/off power applied to the electronic carbon dioxide gas opening/closing valve 110.

Here, the initial carbon dioxide gas injection into the draft beer barrel 10 is sufficient so that the draft beer in the draft beer barrel 10 can be extracted for the first time, so the initial carbon dioxide gas injection switch 140 is turned on for about 5 to 10 seconds, and then, It is immediately turned off so that the electronic carbon dioxide gas on-off valve 110 is closed.

At this time, since the draft beer does not flow in the draft beer external discharge pipe 41, the flow meter 120 recognizes that there is no flow rate of the draft beer, and the electronic contactor 130 causes the power applied to the electronic carbon dioxide gas opening/closing valve 110. Is blocked, and the electronic carbon dioxide gas opening/closing valve 110 is closed, so that the carbon dioxide gas for extraction in the carbon dioxide gas container 20 is maintained in a state that is not injected into the draft beer container 10.

In this state, when the tap lever 43 is raised, the draft beer in the draft beer barrel 10 by the pressure of the carbon dioxide gas for extraction injected into the draft beer barrel 10 is discharged from the draft beer inner discharge pipe 17 and the draft beer outer discharge pipe 41 and the draft beer discharge tap. It is discharged through the discharge part 44 of 42, and in this process, the flow meter 120 installed in the middle of the draft beer external discharge pipe 41 measures the flow of the draft beer discharged through the draft beer external discharge pipe 41. And, the magnetic contactor 130 receiving the measurement signal from the flow meter 120 converts the current direction applied to the electronic carbon dioxide gas on/off valve 110 to the open operation direction by a control circuit (switching circuit) built in itself. , The electronic carbon dioxide gas opening/closing valve 110 is opened so that the carbon dioxide gas for extraction in the carbon dioxide gas container 10 is injected into the draft beer container 10 through the carbon dioxide gas external injection pipe 31 and the carbon dioxide gas internal injection pipe 13 The draft beer in the draft beer barrel 10 is discharged through the draft beer inner discharge pipe 17 and the draft beer external discharge pipe 41 and the discharge part 44.

On the contrary, when the tap lever 43 is lowered, the drainage of draft beer is blocked, and the draft beer does not flow through the draft beer outlet pipe 41, so the flow meter 120 measures that there is no flow of the draft beer, and the flow meter 120 measures The electronic contactor 130 receiving the signal converts the direction of the current applied to the electronic carbon dioxide gas open/close valve 110 to the closed operation direction by a control circuit (switching circuit) built in itself, and the electronic carbon dioxide gas open and close valve 110 Is blocked to cut off the supply of carbon dioxide gas for extraction in the carbon dioxide gas cylinder 20.

Therefore, according to the draft beer discharging system according to the present embodiment, the carbon dioxide gas for extraction in the carbon dioxide gas container 20 lowers the tap lever 43 of the draft beer discharging tap 42, so that the draft beer in the draft beer container 10 is discharged. It is injected into the barrel 10 and is not supplied while the draft beer in the draft beer barrel 10 is not discharged by raising the tap lever 43, so overcarbonation is prevented, and the dissolved carbonic acid in the draft beer is maintained as an appropriate dissolved carbonic acid. Unique flavor can be maintained.

The flow meter 120 may be replaced with a sensor or switch that senses the position of the tap lever 43, that is, the raised position and the lowered position.

When the lower end of the draft beer inner discharge pipe 17 is sufficiently immersed in the draft beer in the draft beer barrel 10, the carbon dioxide gas ejection preventing means 50 includes the first draft beer external discharge pipe 41a and the chamber 51 and the outside of the second draft beer. The discharge pipe (41b) is maintained in a state filled with draft beer, and accordingly, the knitting device (52) is injured so that the first draft beer external discharge pipe (41a) and the second draft beer external discharge pipe (41b) are in communication through the chamber 51. If the draft beer in the draft beer barrel 10 is exhausted and the lower end of the draft beer internal discharge tube 17 is not sufficiently immersed in the draft beer, the knitting device 52 loses buoyancy and settles outside the first draft beer. The discharge pipe 41a and the second draft beer external discharge pipe 41b are blocked to prevent the carbon dioxide gas from being ejected as described above.

In addition, even if the lower end of the draft beer inner discharge pipe 17 is sufficiently immersed in the draft beer in the draft beer barrel 10, the carbon dioxide gas pressure in the carbon dioxide gas barrel 20 decreases (it does not normally decrease, but the carbon dioxide gas in the draft beer barrel is discharged to prevent overcarbonation. In case of performing the function, the pressure in the draft beer barrel may decrease) and the carbon dioxide gas pressure for extraction applied to the surface of the draft beer in the draft beer barrel 10 is applied to the draft beer inner discharge pipe 17, the first draft beer outer discharge pipe 41a, and the chamber When the head pressure of the draft beer filled in (51) and the second draft beer external discharge pipe (41b) is lower, the draft beer internal discharge pipe (17), the first draft beer external discharge pipe (41a), the chamber 51 and the second draft beer external discharge pipe ( 41b) The draft beer filled in the inside of the draft beer barrel 10 reverses (falls down), and the knitting device 52 loses its buoyancy and descends to block the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b. Even if the pressure of the carbon dioxide gas for extraction in the draft beer barrel 10 returns to normal, the draft beer in the draft beer barrel 10 cannot be discharged.

Therefore, in the draft beer discharge system according to the present embodiment, the draft beer filled in the first draft beer external discharge pipe 41a and the second draft beer external discharge pipe 41b, the chamber 51 and the draft beer internal discharge pipe 17 is filled in the draft beer barrel 10.

The draft beer backflow prevention means 200 is a chamber of the draft beer internal discharge pipe 17, the first draft beer external discharge pipe 41a, and the carbon dioxide gas discharge preventing means 50 as the draft beer in the draft beer barrel 10 is discharged through a normal discharge process. (51), when the draft beer filled in the second draft beer external discharge pipe (41b) is lower than the head pressure of the draft beer in the draft beer discharge pipe (40), the draft beer filled into the draft beer barrel (10) Reverse flow is prevented, and accordingly, the draft beer filled in the first draft beer external discharge pipe 41a and the draft beer internal discharge pipe 17 is prevented from flowing backward to the draft beer barrel 10.

Therefore, when the draft beer in the draft beer barrel 10 is exhausted by the cooperation of the carbon dioxide gas ejection prevention means 50 and the draft beer backflow prevention means 200, the extraction of carbon dioxide gas for extraction and the bottom of the draft beer barrel 10 In addition to preventing the phenomenon of contaminating the surrounding by erupting a trace amount of draft beer remaining in the bubble, the pressure of carbon dioxide gas for extraction applied to the surface of the draft beer in the draft beer barrel 10 is applied to the draft beer in the draft beer discharge means 40 When the tap lever 43 is lowered when the pressure is lower than the head pressure of and returns to the normal pressure, the draft beer discharge cock 42, the second draft beer external discharge pipe 41b, the chamber 51, and the first draft beer external discharge pipe 41a And since the draft beer filled in the draft beer inner discharge pipe 17 is immediately discharged, and the draft beer in the draft beer barrel 10 is discharged thereafter, the draft beer can be discharged immediately without separate restoration work and business preparation work.

That is, when the draft beer is exhausted in the draft beer barrel 10, the gas is blocked by the sinking of the lower portion of the knitting 52 by the carbon dioxide gas ejection preventing means 50, and the draft beer is replaced. In order to prevent over-carbonation, the check valve 200 decreases and reverses flow even though the draft beer remains in the draft beer barrel 10 due to a decrease in the pressure of the carbon dioxide gas for extraction in the draft beer barrel 10 when the carbonic acid is controlled and discharged. There are cases, but this can be prevented.

In the above-described data storage and display process, the flow meter 46 for each type of draft beer for each recognition tag reader 320 tagged with an RF tag (TAG), and for each RF tag (TAG) tagged in the recognition tag reader 320 The total accumulated amount for each table, along with the amount of discharge measured in the discharge, the unit price previously stored in the discharge, and the accumulated amount are stored in the data storage unit 331 under the control of the POS terminal control unit 333 In addition, it is displayed on the display panel 332.

In the above-described payment process, when a table number to be calculated is selected by touching it among table numbers displayed on the display panel 332, the amount is displayed.

In this state, as in a typical POS terminal, the payment is completed by touching the payment button displayed on the display panel 332. Payment can be made by ordinary cash payment or card payment.

In the above-described payment process, when one RF tag (TAG) is registered in one table, the total accumulated amount per table can be collectively paid, and when a plurality of RF tags (TAG) are registered in one table, the table You can pay the total accumulated amount for each unit in bulk, or you can pay the accumulated amount for each RF tag (TAG) using Dutch Pay.

That is, when a plurality of RF tags (TAG) are registered in one table, if the table number field displayed on the display panel 332 is touched, draft beer type and discharge amount, amount, and accumulated amount for each RF tag (TAG) are listed. In addition to being displayed in a form, it can be configured to switch to a list display screen in which the accumulated amount of the entire table is displayed, so that a Dutch pay payment is possible.

When the payment is completed, the unique RF tag number stored for each table number stored in the data storage unit 332 under the control of the POS terminal controller 333 is deleted under the control of the POS terminal controller 333 and the corresponding table The registration of the RF tag (TAG) registered to the number is canceled.

The unregistered RF tag (TAG) cannot be used arbitrarily, and if the customer loses the registered RF tag (TAG), the lost RF tag (TAG) becomes an unregistered RF tag when payment of the amount in the table is completed. Lost RF tag can be prevented from being arbitrarily used.

In addition, since the registration of the corresponding RF tag (TAG) is automatically terminated when the calculation of the amount of each table is completed, the hassle of unregistering by tagging the RF tag to the tag reader for deregistration can be avoided.

The unregistered RF tag (TAG) can be re-registered and used by the method described above.
