COCA-COLA® is a registered trademark of The Coca-Cola Company, Atlanta, Ga., U.S.A. Other names, symbols, designs, or logos used herein may be registered trademarks, trademarks or product names of The Coca-Cola Company or other companies.
This invention relates to product dispensers, and in particular, relates to systems and methods for providing individually monitoring and controlling the dispense of a plurality of product forming ingredients.
Conventional beverage dispensers can pour a beverage by combining a syrup, sweetener, and/or water. These conventional beverage dispensers generally offer a finite variety of beverage selections that incorporate different kinds of syrups. The offered beverage selections can include branded and non-branded beverage selections. As an example, a single conventional dispenser using several different kinds of syrup might be able to offer choices of COCA-COLA™, DIET COCA-COLA™, SPRITE™, and a few other branded or non-branded beverage selections.
In order to dispense a particular beverage, conventional beverage dispenses typically actuate one or more solenoids, switches and/or valves associated with the various ingredients of the beverage. The associated solenoids, switches and/or valves for each ingredient are typically actuated for a predetermined period of timer, thereby causing a predetermined amount of ingredients to be dispensed for the selected beverage.
One problem with these types of conventional beverage dispensers is that the dispense quality of a selected beverage can be lowered or degraded if one or more of the ingredients for the selected beverage are not being dispensed properly. For example, a conventional dispenser may dispense a low quality COCA-COLA™ beverage if the COCA-COLA™ syrup is not being dispensed properly and/or if the source for the COCA-COLA™ syrup is empty or approximately empty. Additionally, it can be difficult for a customer or user of the dispenser to identify the low quality beverage. Furthermore, as more and more ingredients are combined to form or dispense a selected beverage, it can be difficult for a customer to identify the one or more ingredients that are not dispensed properly and, therefore, are contributing to the lower beverage quality.
Accordingly, there is a need for improved systems and methods for monitoring and control the dispense of a plurality of product forming ingredients.
Some or all of the above needs and/or problems may be addressed by embodiments of the invention.

With regards to the ingredient matrix 112, there is illustrated in
For purposes of disclosure, beverage forming packages, such as 114A-114Q, may be collectively or generally referred to as beverage forming ingredient package 114. Each beverage forming ingredient package 114 may be manufactured as a pouch of liquid secured in a plastic ridged container to allow insertion into the ingredient matrix 112. When inserted into the ingredient matrix 112, the pouch may be pierced by at least one fitting or other suitable piercing device, allowing the liquid in the pouch to be pumped or otherwise metered by pumps 120 and/or valves 125 in precise ratios to form the desired beverage. Additionally, one or more sensors, such as sensors 127, may monitor the amount or volume of liquid that is pumped from a beverage forming ingredient package 114. One or more sensors 127 may also be utilized to aid in the detection of a beverage forming ingredient package 114 that is approximately empty and/or not flowing properly. For example, a capacitive sensor may be situated between a beverage forming ingredient package 114 and an associated pump 120. The capacitive sensor may detect each time that liquid is drawn into the pump 120. As an example, the capacitive sensor may detect the flexing of a metal strip each time that liquid is drawn into the pump 120. If no flex is detected by the capacitive sensor, then a determination may be made by a controller in communication with the capacitive sensor, such as controller 105 or node controller 310A shown in
In some instances, other ingredients, components, or beverage forming additives may be inserted or otherwise operatively connected with the ingredient matrix 112. For instance, a carbonated water supply 114O, a sweetener 114P, and a water supply 114Q may be operatively connected with the ingredient matrix 112. These ingredients, components, or beverage forming additives may be in the form of a pouch, or may be in another configuration suitable for access by the ingredient matrix 112. For example, one or more of these ingredients, components, or beverage forming additives may be supplied to the ingredient matrix 112 via suitable input tubing from respective beverage forming ingredient sources.
In the examples of the carbonated water supply 114O and the water supply 114Q, a continuous supply of liquid like carbonated water, water and/or other continuous ingredient supplies can be provided by a combination of pumps 120, valves 125, and/or variable orifice regulators to meter and/or control the flow of liquid, carbonated water, water, or other ingredient supplies during the formation of the beverage. In a continuous supply example, the carbonated water supply 114O and the water supply 114Q may be connected to the ingredient matrix 112. Additionally, in accordance with some embodiments of the invention, one or more beverage forming ingredients may be circulated through a prechiller (not shown) before being supplied to the ingredient matrix 112. For example, carbonated water and water may be respectively supplied from the carbonated water supply 114O and the water supply 114Q and circulated through one or more prechillers prior to being supplied to the ingredient matrix 112. Additionally or alternatively, one or more beverage forming ingredients may be supplied from refrigerated sources.
In one example, sweetener 114P may be a non-nutritive sweetener (NNS), high fructose corn syrup (HFCS), or other types or kinds of sweetener as may be required and/or desired in a particular embodiment. In this example, the sweetener 114P can be a pouch capable of being connected to the ingredient matrix 112. Additionally, in some embodiments, a plurality of sweeteners may be supplied to the ingredient matrix 112.
In one embodiment, some of the beverage forming ingredients 114 referred to as pungent may be limited to selected ingredient matrix 112 locations. In this regard, pungent ingredients are so strong that once a pungent ingredient is drawn through dispenser tubing in the beverage forming dispenser the tubing is permanently flavored and any fluids that pass through the tubing will be tainted with the pungent taste. As such, once a pungent ingredient is used in the matrix, it may be desirable to limit the replacement and/or addition of other pungent ingredients to certain of the ingredient matrix locations to maintain a premium quality beverage.
Also in one embodiment, certain of the beverage forming ingredient packages 114 may require agitation to keep the ingredient mixed. In these cases, the location of such ingredients in the ingredient matrix 112 may be limited to ingredient matrix locations that can be agitated as may be required and/or desired in a particular embodiment.
Additionally, one or more continuous ingredient supplies may be connected to the ingredient matrix 112 in respective locations in which the continuous ingredient supplies may be agitated. For example, a continuous supply of ice may be connected to the ingredient matrix 112, and ice may be agitated prior to, during, and/or after the dispense of a beverage.
Also in one embodiment, certain of the beverage forming ingredient packages 114 may require antimicrobial tubing and/or dispenser parts. These beverage forming ingredient packages 114 may include milk, dairy, soy, and/or other types and kinds of beverage forming ingredient packages. In these cases, the location of such ingredients in the ingredient matrix 112 may be limited to ingredient matrix locations that utilize the appropriate antimicrobial tubing and/or dispenser parts as may be required and/or desired in a particular embodiment.
In one embodiment, for the most part, there may be a relationship between a particular beverage forming ingredient package 114 and one or more respective pumps 120 and/or valves 125. For example, there may be a one-to-one relationship between a particular beverage forming ingredient package 114 and a pump 120 and/or valve 125. As another example, there may be a four-to-one relationship between a particular beverage forming ingredient package 114 and associated pumps 120 and/or valves 125. A wide variety of relationships between a particular beverage forming ingredient package 114 and associated pump(s) and/or valve(s) may be utilized as desired in various embodiments of the invention. The utilization of more than one pump 120 and/or valve 125 may facilitate the ability to draw a higher volume of a beverage ingredient from a beverage forming ingredient package 114 in a shorter period of time. In a few cases, it may be desirable to utilize a plurality of pumps and/or valves on a single ingredient to be able to draw a higher volume of liquid from the package in a shorter period of time. One such ingredient in which it may be desirable to use a plurality of pumps 120 and/or valves 125 to be able to draw a higher volume of liquid from the package 114 in a shorter period of time can be the sweetener 114P.

In one embodiment, correct beverage forming ingredient package 114 insertion into the ingredient matrix 112 may be double checked or otherwise verified by scanning a machine readable code on the package (illustrated as 118A) and scanning a machine readable code located on the ingredient matrix 112 at the point of insertion (illustrated as 118B). In this regard, the controller 105 may then check or verify that the beverage forming ingredient package 114 is correctly located in the ingredient matrix 112. Additionally or alternatively, a machine readable code reader 170A that is associated with a particular matrix location in the ingredient matrix 112, such as a radio frequency identification (RFID), may be utilized to read an RFID tag (illustrated as 118A) associated with the beverage forming ingredient package 114A prior to, during, and/or subsequent to its insertion into the ingredient matrix 112. In this regard, a controller, such as controller 105 may be used to obtain information related to or associated with the beverage forming ingredient package 114A, and use such information to identify or otherwise determine the location within the ingredient matrix 112 of the beverage forming ingredient package 114A.
A determination may also be made as to whether the beverage forming ingredient package 114A has been inserted into an appropriate location within the ingredient matrix 112. In accordance with one or more embodiments of the invention, a plurality of machine readable code readers may be associated with respective locations within the ingredient matrix 112. As beverage forming ingredient packages 114 are inserted into the ingredient matrix 112 and scanned, package installation personnel may be informed where the beverage forming ingredient package 114 is located in the ingredient matrix 112 by way of one or more suitable output devices 160, such as a light emitting diode (LED) display indicator. The package installation personnel may additionally or alternatively be informed by way of other types and kinds of output devices or display indicators as may be required and/or desired in a particular embodiment. Other embodiments can include output devices such as LCD screens, input/output (I/O) interfaces, and audio interfaces.
The package installation personnel may also be informed via one or more suitable output devices 160 of any determination(s) that a beverage forming ingredient package has been inserted into an incorrect location within the ingredient matrix 112. For example, if an optimal location in the ingredient matrix 112 has been determined for a beverage forming ingredient package, such as 114A, utilizing machine readable code reader 155, then the insertion into the optimal location may be verified by a machine readable code reader associated with the optimal location, such as machine readable code reader 170A. The package installation personnel may be informed of the correct insertion. If the beverage forming ingredient package is inserted into a different location than the optimal location, then a machine readable code reader associated with the different location may be utilized in a determination that the beverage forming ingredient package has not been properly inserted into the optimal location. The package installation personnel may then be notified of the improper insertion. As another example, if a beverage forming ingredient package, such as 114A, is replaced in the ingredient matrix 112 with a new beverage forming ingredient package, a machine readable code reader associated with the location in the ingredient matrix 112 may be utilized in association with a determination that the new beverage forming ingredient package may be inserted into the location. For example, if the location is associated with a cherry syrup, then a determination may be made as to whether the new beverage forming ingredient package is a cherry syrup.
Furthermore, in one embodiment, a RFID tag associated with a beverage forming ingredient package, such as 114A, may be written to and/or modified such that the beverage forming ingredient package 114A is prevented or otherwise limited from being inserted into a second or other beverage forming dispenser. In this regard, should service personnel attempt to read the RFID tag a second time in an attempt to relocate the package 114A into a second beverage forming dispenser it would be known to a controller associated with the second beverage forming dispenser that the package 114A has previously been inserted into a different beverage dispenser, and as such, would not allow the package 114A to be operated in a second ingredient matrix. In operation, this can prevent partially used beverage forming ingredient packages from being transferred between beverage forming dispensers. Similarly, a RFID tag associated with a beverage forming ingredient package, such as 114A, may be written to and/or modified such that the beverage forming ingredient package 114A is prevented or otherwise limited from being inserted into certain locations in the ingredient matrix 112 of a beverage forming dispenser, such as beverage forming dispenser 100.

Such information may be used to identify within the ingredient matrix 112 an optimum or desired matrix location for placement of the beverage forming ingredient package 114A. In this regard, information related to the beverage forming ingredient package 114A may be manually entered into the controller 105 such that an optimum or desired matrix location can be identified. Once identified, a service personnel may be informed of the optimum or desired location within the ingredient matrix 112 by way of a suitable output devices 160, such as a light emitting diode (LED) display indicator, and/or informed by way of other types and kinds of output devices or display indicators as may be required and/or desired in a particular embodiment. Other embodiments may include output devices such as LCD screens, input/output (I/O) interfaces, and audio interfaces.
Furthermore, in one embodiment, a RFID tag associated with a beverage forming ingredient package, such as 114A, may be written to and/or modified such that the beverage forming ingredient package 114A is prevented or otherwise limited from being utilized by a second or other beverage forming dispenser. In this regard, should service personnel attempt to read the RFID tag a second time in an attempt to relocate the package into a second beverage forming dispenser it would be known to a second controller, via tag information or a network component, that the package has previously been inserted into a different beverage dispenser and as such would not allow the package to be operated in a second ingredient matrix. In operation, this may prevent or otherwise limit partially used packages from being transferred between beverage forming dispensers by way of determining via tag information or a network component the amount of an ingredient remaining within a particular beverage forming ingredient package.
In one embodiment, information associated with an amount of an ingredient remaining in a beverage forming ingredient package 114 may be written to a RFID tag associated with a beverage forming ingredient package, such as 114A. Such information may be written to the RFID tag after each use or prior to removal of the beverage forming ingredient package 114A from the ingredient matrix 112.

An association between a plurality of beverage forming ingredient packages, such as 114A-114D, and a plurality of pumps, such as 120A-120D, may be stored as a last known good association such that each time the beverage forming dispenser is powered up and/or reset, a check for conflicts of the current association between the plurality of beverage forming ingredient packages and the pumps can be made. Such conflicts may include, for example and not as a limitation, a pungent beverage forming ingredient package being incorrectly located in the ingredient matrix, an agitation required beverage forming ingredient package being located in a non-agitated ingredient matrix location, at least two beverage forming ingredient packages being age and/or otherwise incompatible, and/or other types and kinds of conflicts, monitoring, and determination as may be required and or desired in a particular embodiment.
In one embodiment, as related to a service technician making repairs or a service person restocking the beverage forming dispenser, beverage forming ingredient packages and pumps may from time to time be removed, replaced, exchanged, or in other ways the dispenser and ingredients modified. In these conditions, it may be likely that beverage forming ingredient packages are moved to different slots and/or pump/valve assemblies are changed. As such, when the beverage forming dispenser is next powered up or reset only then will the changes be determinable and of operational consequence. For example and not as a limitation, if there is a beverage forming ingredient package in the incorrect or an unsuitable ingredient matrix location, the incorrect recipe may be poured. In addition, a replacement pump associated with an incorrect or unsuitable beverage forming ingredient package may cause the ratio of the pour to be incorrect resulting in poor beverage quality and/or taste. In this regard, often different ingredients have different viscosities. Furthermore, as viscosity of the ingredients change, from ingredient to ingredient, various characteristics of the pumps may be changed or otherwise adjusted in order to deliver the correct or suitable ingredient at a suitable ratio per the recipe.
Characteristics may be referred to herein as operational characteristics and may include, for example and not as a limitation, electrical and/or mechanical characteristics of at least one of the pumps to control or compensate for a viscosity of a particular ingredient being pumped.
An advantage of an embodiment of the invention is that once a known good association exists, the dispenser may obtain information related to a plurality of beverage forming ingredient packages located in the ingredient matrix, determine an association related to the operational relationship between each of the plurality of beverage forming ingredient packages and each of a plurality of pumps, determine if the association has changed by comparison to the last known good association, and modify the association if the association has changed to accommodate the new association.
In addition, another advantage of an embodiment of the invention can be that the plurality of said beverage forming ingredient packages configured within the ingredient matrix may be compared to a database of beverage recipes to form an available beverage menu.

In one embodiment, once a beverage is selected for dispense, the controller 105 may access a recipe to form the selected beverage from an associated database, such as database 130. The recipe may indicate the beverage forming ingredients that are needed to dispense the selected beverage and the ratio of the needed ingredients. The controller 105 may communicate information associated with a dispense of a needed beverage forming ingredient to a control node, such as 305A, associated with the beverage forming ingredient. The communicated information 105 may include information associated with the desired ratio, a desired flow rate of the beverage forming ingredient, a desired volume of the beverage forming ingredient, a desired cup size for the selected beverage, and/or other information as may be desired in an embodiment of the invention. The controller 105 may also communicate an order or command to the control node 305A to commence the dispense of the beverage forming ingredient utilizing the desired flow rate, ratio and/or volume. The commence order may be communicated concurrently with or subsequent to the communication of the information associated with the desired flow rate ratio and/or volume. In response to the commence order, the control node 305A may cause the beverage forming ingredient to be dispensed in accordance with the desired flow rate, ratio and/or volume. The control node 305A, in association with the pumping technology 325A and the measurement technology 330A may monitor and precisely control the dispense of the beverage forming ingredient. In this regard, each beverage forming ingredient for a selected beverage may be precisely monitored and controlled by associated control nodes, such as 305A-N.

Following the receipt of customer selections, processing then moves to block 415.
In block 415, a database, such as database 130, may be accessed to identify the ingredients of the selected beverage. The accessed recipe may indicate the beverage forming ingredients that are combined to form the selected beverage. Additionally, the accessed recipe may indicate a ratio of the various beverage forming ingredients for the selected beverage. For example, the ratio of the various beverage forming ingredients may be specify and/or be utilized to determine rates at which each of the beverage forming ingredients should be pumped or dispensed in order to form the selected beverage. The rates at which each of the beverage forming ingredients should be pumped or dispensed in order to form the selected beverage may also be referred to as flow rates. Following the accessing of the database 130, processing may move to block 420.
In block 420, the dispense of each of the beverage forming ingredients specified in the recipe may be directed in order to form the selected beverage. In certain embodiments of the invention, a central controller, such as 105, may direct one or more control nodes, such as 305, associated with the beverage forming ingredients to dispense the beverage forming ingredients in order to form the selected beverage. The one or more control nodes may then control the pumping of the beverage forming ingredients. In other embodiments of the invention, a central controller, such as 105, may directly control the pumping of the beverage forming ingredients. Following the directions of the dispense of each of the beverage forming ingredients, processing may move to block 425.
In block 425, the pumping and/or dispense of one or more of the beverage forming ingredients may be monitored. The monitoring of the beverage forming ingredients may be conducted by a central controller, such as controller 105, and/or by one or more control nodes, such as node 305. Additionally, suitable measurement technology, such as measurement technology 330A-330N, may be utilized in association with the controller 105 and/or the one or more control nodes in order to monitor the beverage forming ingredients.
Based at least in part on the monitoring of the pumping and/or dispense of one or more of the beverage forming ingredients, one or more determinations may be made as to whether the monitored beverage forming ingredients are dispensing properly and/or dispensing at a desired rate. If it is determined that a monitored beverage forming ingredient is not dispensing properly and/or is not being dispensed at a desired rate, the pumping of the monitored beverage forming ingredient may be adjusted as desired in an embodiment.
The example of a method for receiving customer input for a selected beverage and directed the dispense of the selected beverage may end following block 425.
According to certain embodiments of the invention, a beverage forming dispenser, such as dispenser 100, may be configured to dispense portion controlled amounts or volumes of selected beverages. The portion control dispenses may be configured according to input and/or preferences of a customer, consumer, or user of the beverage forming dispenser 100. The portion control dispenses may be quickly and easily programmed and configured for the beverage forming dispenser 100. In one embodiment, portion control dispenses may be calibrated or initialized for multiple beverage selections concurrently with one another.

In this regard, a portion control dispense may be performed by the beverage forming dispenser 100 in response to customer input that includes a beverage selection and a cup size selection.
In block 505, a dispense ratio for a beverage ingredient of a selected beverage may be determined. The dispense ratio for the beverage ingredient may be determined based at least in part on a recipe for the selected beverage, such as a recipe that is accessed from a suitable database of a beverage forming dispenser 100, such as database 130. The dispense ratio may define an amount of the beverage ingredient that needs to be dispensed relative to the dispense of amounts of one or more other ingredients of the selected beverage. For example, a selected beverage may be formed of approximately ten parts carbonated water and approximately one part flavor syrup. Thus, the dispense ratio for the selected beverage may be expressed as a 10:1 ratio. In this example, for any amount of syrup that is dispensed, approximately ten times that amount of carbonated water should be dispensed. Alternatively, for any amount of beverage that is dispensed, approximately one eleventh ( 1/11) of that amount of beverage should be syrup and approximately ten elevenths ( 10/11) of that amount of beverage should be carbonated water.
In block 505, the dispense ratio for a beverage ingredient of a selected beverage may be determined. Using the example above for the syrup, the ratio of syrup to carbonated water based at least in part on the recipe for the selected beverage may be expressed as 1:10. Accordingly, the dispense ratio for the syrup may be expressed as approximately 1:11. In other words, for an amount of beverage that is dispensed, approximately one eleventh ( 1/11) of that amount of beverage should be syrup. Once a dispense ratio has been determined for a beverage ingredient, processing may move to block 510.
In block 510, a flow rate for the dispense of the selected beverage may be determined or identified. The flow rate for the dispense of the selected beverage may be based at least in part on characteristics associated with the selected beverage, for example, foaming characteristics of the selected beverage. It may be desirable to dispense a beverage with higher foaming characteristics at a lower flow rate or dispense rate than a beverage with lower relative foaming characteristics. For example, it may be desirable to dispense a carbonated beverage at a lower flow rate than a non-carbonated beverage. Any characteristics associated with the selected beverage that are utilized in a determination of the flow rate for dispense may be stored in a suitable memory associated with a beverage forming dispenser 100, such as memory 180 or database 130. As an alternative to determining a flow rate for the selected beverage, a flow rate may be defined and pre-stored for the selected beverage in a suitable memory. For example, a default flow rate for the selected beverage may be stored in association with the recipe for the selected beverage.
The flow rate for the dispense of the selected beverage may be independent of a cup size that may be selected for dispense or, alternatively, the flow rate for dispense of the selected beverage may be determined and/or adjusted based at least in part on the cup size. In certain embodiments of the invention, it may be desirable to dispense a selected beverage at a higher flow rate if the selected beverage is being dispensed into a larger cup. Additionally, the flow rate of any beverage may be adjusted during the dispense of the selected beverage as the cup begins to fill up in order to minimize splash and/or splatter associated with the dispense.
Following the determination of a flow rate for dispense of the selected beverage, processing may move to block 515.

In one embodiment, the determined flow rate and/or the determined dispense ratio may be communicated to the control node 305. In certain embodiments of the invention, the control node 305 may be operable to determine or access information associated with the selected beverage, such as, the recipe for the beverage and/or a flow rate for the beverage, and the control node 305 may be operable to determine dispense parameters for the beverage ingredient.
Following the communication of the one or more dispense parameters associated with the dispense of a beverage ingredient to a control node, processing may move to block 520.
In block 520, an instruction to commence the dispense of the selected beverage may be communicated to the one or more control nodes associated with the dispense of the various ingredients of the selected beverage. Alternatively, respective instructions to commence the dispense of each of the beverage ingredients may be respectively communicated to the one or more control nodes associated with the pumping and/or dispense of the beverage ingredients. The one or more control nodes may be operable to initiate the pumping of the various ingredients of the selected beverage in response to the instruction(s) to commence the dispense. Operations may then move to block 525.
In block 525, an instruction to cease the dispense of the selected beverage may be communicated to the one or more control nodes associated with the dispense of the various ingredients of the selected beverage. Alternatively, respective instructions to cease the dispense of each of the beverage ingredients may be respectively communicated to the one or more control nodes associated with the pumping and/or dispense of the beverage ingredients.

Alternatively, the time of dispense for the selected beverage may be monitored and the communication of the instruction(s) to cease the dispense may be based at least in part on the monitoring of the time of dispense. Alternatively, the communication of the instruction(s) to cease dispense may be based at least in part on customer input received via one or more suitable input devices, such as input devices 165 shown in
The example of a method for directing a control node associated with a beverage forming ingredient to dispense the associated beverage forming ingredient may end following block 525.
Although the method of
In block 605, a control node associated with a beverage forming ingredient, such as node 305, may receive one or more dispense parameters associated with the dispense of a beverage forming ingredient. The beverage forming ingredient may be an ingredient of a selected beverage. The one or more dispense parameters may be received via a suitable network. A wide variety of dispense parameters may be received by the control node 305 as desired in embodiments of the invention including, but not limited to, a recipe of a selected beverage, a ratio of the ingredients of the selected beverage, a dispense ratio for the selected beverage, a flow rate for the selected beverage, a flow rate for the beverage ingredient, a cup size for the dispense, a type of ice for the dispense, and/or an amount, volume, or ratio of ice for the dispense. In one embodiment, the determined flow rate and/or the determined dispense ratio may be received by the control node 305. In certain embodiments of the invention, the control node 305 may be operable to determine or access information associated with the selected beverage, such as, the recipe for the beverage and/or a flow rate for the beverage, and the control node 305 may be operable to determine dispense parameters for the beverage ingredient. Once the one or more dispense parameters are received, operations may move to block 610.
In block 610, the control node 305 may configure the dispense of the beverage forming ingredient for the selected beverage. The control node 305 may configure the dispense of the beverage forming ingredient based at least in part on at least one of the one or more received dispense parameters. Additionally, the control node 305 may configure the dispense based at least in part on characteristics associated with the beverage forming ingredient that are stored in a suitable memory associated with the control node 305, such as a memory associated with a node controller of the control node 305. In certain embodiments, at least a portion of the characteristics associated with the beverage forming ingredient may be stored in a memory that is located remote to the control node 305 and communicated to the control node via a network. Many different characteristics associated with the beverage forming ingredient may be utilized as desired in accordance with embodiment of the invention including, but not limited to, one or more parameters associated with a pumping performance of the beverage forming ingredient, one or more parameters associated with fluid characteristics of the beverage forming ingredient, and/or one or more parameters associated with a flow rate or a flow rate range for the beverage forming ingredient and/or the pumping technology. An example of a parameter associated with a pumping performance is a viscosity of the beverage forming ingredient. Another example of parameters associated with pumping performance are parameters associated with the functionality, characteristics, and/or the capabilities of the pumping technology associated with the beverage forming ingredient. Examples of parameters associated with a flow rate or a flow rate range may include a target flow rate for the beverage forming ingredient and/or the pumping technology and one or more threshold values for the flow rate. For example, an acceptable flow rate range may be established for the beverage forming ingredient and/or the pumping technology. The characteristics stored by the control node 305 may be pre-stored, may be received from another component of the beverage forming dispenser 105, such as, a central controller or a RFID reader/writer, and/or may be received from an external component.
Additionally, the control node 305 may configure the dispense of the beverage forming ingredient based at least in part on the pumping technology associated with the beverage forming ingredient. The type of pumping technology and/or the quantity of pumps associated with the pumping technology may be taken into account. For example, if multiple pumps are associated with a beverage forming ingredient, the dispense may be configured differently than if only a single pump were utilized. If for example, four pumps are associated with a beverage forming ingredient, then each of the four pumps may be configured to pump approximately one-fourth of the amount or volume of a beverage forming ingredient that a single pump may be configured to pump if only a single pump is associated with the beverage forming ingredient.
In one embodiment of the invention, configuring the dispense of the beverage forming ingredient may include determining and configuring an expected flow rate for the beverage forming ingredient. The expected flow rate for the beverage forming ingredient may be determined based at least in part on the one or more received dispense parameters or, alternatively, the expected flow rate for the beverage forming ingredient may be received in conjunction with the one or more dispense parameters. The expected flow rate for the beverage forming ingredient may be determined based at least in part on the flow rate for the selected beverage and the dispense ratio for the beverage forming ingredient. For example, if the flow rate for the selected beverage is approximately three (3) ounces per second and the dispense ratio for the beverage forming ingredient is approximately one-eleventh ( 1/11), then the expected flow rate for the beverage forming ingredient may be determined to be approximately 3 times ( 1/11) ounces per second, or approximately 0.27 ounces per second.
The expected flow rate for the beverage forming ingredient may be utilized in a configuration of the pumping technology associated with the beverage forming ingredient. For example, if four pumps are associated with a beverage forming ingredient, then each of the four pumps may be configured to pump approximately 0.0675 ounces per second (or approximately 0.27 ounces per second divided by four).
Following the configuration of the dispense of the beverage forming ingredient, operations may move to block 615.
In block 615, the control node 305 may receive a command to commence a dispense of the beverage forming ingredient. Following the receipt of the command to commence a dispense of the beverage forming ingredient, operations may move to block 620.
In block 620, the control node 305 may commence pumping of the beverage forming ingredient by directing pumping technology associated with the beverage forming ingredient, such as pumping technology 325A, to commence pumping the beverage forming ingredient. The pumping of the beverage forming ingredient may be configured based at least in part on the dispense configuration of the beverage forming ingredient. Once the pumping of the beverage forming ingredient is commenced, operations may move to block 625.
In block 625, the control node 305 may monitor the pumping of the beverage forming ingredient. Suitable measurement technology, such as measurement technology 330A, may be utilized in association with the control node 305 in order to monitor the beverage forming ingredients.
Based at least in part on the monitoring of the pumping beverage forming ingredient, one or more determinations may be made as to whether the beverage forming ingredient is being dispensed properly and/or whether the beverage forming ingredient is being dispensed at a desired rate. If it is determined that the beverage forming ingredient is not dispensing properly and/or is not being dispensed at a desired rate, the pumping of the beverage forming ingredient may be adjusted as desired in an embodiment.
The monitoring and optional adjusting of the dispense of the beverage forming ingredient may be continued until a command is received to cease the dispense of the beverage forming ingredient. Following the monitoring of a beverage forming ingredient in block 625, processing may move to block 630.
In block 630, a determination may be made as to whether a command to cease the dispense of a beverage forming ingredient has been received. If a command to cease the dispense of a beverage forming ingredient has not been received, then operations may move to block 625 and the monitoring of the beverage forming ingredient may continue. If, however, a command to cease the dispense of a beverage forming ingredient has been received, then operations may end.
Various embodiments of the invention may control the dispense of a beverage forming ingredient in many different ways as may be desired in certain embodiments. For example, as an alternative to dispensing a beverage forming ingredient until a cease dispense command is received, a cup size selection may be utilized to determine an amount or volume of a beverage forming ingredient to include in a selected beverage. The determined amount or volume of the beverage forming ingredient may then be precisely dispensed. The use of a flow rate in an embodiment of the invention may provide for the dispense of a beverage forming ingredient that is independent of a cup size selection and may be desirable in certain situations, for example, when the dispense of a selected beverage is controlled manually by a customer.
The example of a method for controlling the dispense of a beverage forming ingredient by an associated control node may end once a command to cease the dispense of a beverage forming ingredient is received.
In block 705, one or more flow characteristic of a beverage forming ingredient that is being pumped may be measured and/or determined. For example, a flow rate of the beverage forming ingredient that is being pumped may be measured and/or determined utilizing suitable measurement technology, such as measurement technology 330A, and associated control logic. As another example, an amount or volume of a beverage forming ingredient that is being pumped may be measured and/or determined utilizing suitable measurement technology, such as measurement technology 330A, and associated control logic.
According to one embodiment of the invention, one or more flow characteristics of a beverage forming ingredient that is being pumped may be measured and/or determined for a predetermined time interval or a predetermined period of time. Many different predetermined time intervals may be utilized in accordance with embodiments of the invention, such as, a predetermined time interval of approximately 50 milliseconds (ms). For example, the flow rate of the beverage forming ingredient and/or the amount or volume of beverage forming ingredient that is pumped may be determined for the predetermined period of time. Once the one or more flow characteristics of a beverage forming ingredient are measured and/or determined, then processing may move to block 710.
In block 710, one or more of the measured and/or determined flow characteristics may be compared to one or more respective expected flow characteristics. For example, a measured or determined flow rate of the beverage forming ingredient may be compared to an expected flow rate of the beverage forming ingredient. As another example, a measured or determined volume or amount of pumped beverage forming ingredient may be compared to an expected volume or amount of pumped beverage forming ingredient.
According to an embodiment of the invention, one or more of the measured and/or determined flow characteristics for a predetermined time interval may be compared to respective expected flow characteristics for the predetermined time interval. For example, a measured or determined flow rate for the preceding 50 ms may be compared to an expected flow rate for the preceding 50 ms for the beverage forming ingredient. As another example, a measured or determined volume or amount of pumped beverage forming ingredient for the preceding 50 ms may be compared to an expected volume or amount of pumped beverage forming ingredient for the preceding 50 ms. In certain embodiments of the invention, each of the expected flow characteristics may be constant throughout the dispense of the beverage forming ingredient for the selected beverage; however, it will be understood that at least a portion of the expected flow characteristics may be dynamically changed or updated during the dispense of the beverage forming ingredient based at least in part on the measured and/or determined flow characteristics. Once one or more of the measured and/or determined flow characteristics are compared to respective expected flow characteristics, operations may move to block 715
In block 715, a determination may be made as to whether there is a difference between one or more of the measured and/or determined flow characteristics and respective expected flow characteristics. In certain embodiments, a tolerance and/or error factor may be incorporated into the determination of whether there is a difference as desired in embodiments of the invention.
As an example of determining whether there is a difference between a measured flow characteristic and an expected flow characteristic, a measured flow rate of a beverage forming ingredient for a predetermined time interval may he compared to an expected flow rate or target flow rate of the beverage forming ingredient for the predetermined time interval. For this example, it will be assumed that the measured flow rate of the beverage forming ingredient for the preceding 50 ms is approximately 0.8 ounces per second and the expected flow rate of the beverage forming ingredient for the preceding 50 ms is approximately one (1) ounce per second. Also, for this example, a tolerance of plus or minus ten percent may be included in the determination of whether there is a difference. In this example, it may be determined that there is a difference between the measured flow rate and the expected flow rate of the beverage forming ingredient. If the parameters set forth above are utilized, except the measured flow rate is approximately 0.95 ounces per second for the preceding 50 ms, then it may be determined that there is no difference between the measured flow rate and the expected flow rate.
As another example of determining whether there is a difference between a measured flow characteristic and an expected flow characteristic, a measured amount or volume of a beverage forming ingredient that is pumped in a predetermined time interval may be compared to an expected amount or volume or target amount or volume to be pumped in the predetermined time interval. For this example, it will be assumed that the measured volume of the beverage forming ingredient for the preceding 50 ms is approximately 40 microliters (mL) and the expected volume of the beverage forming ingredient for the preceding 50 ms is approximately 50 mL (mL). Also, for this example, a tolerance of plus or minus ten percent may be included in the determination of whether there is a difference. In this example, it may be determined that there is a difference between the measured volume and the expected volume of the beverage forming ingredient. If the parameters set forth above are utilized, except the measured volume is approximately 49 microliters (mL) for the preceding 50 ms, then it may be determined that there is no difference between the measured volume and the expected volume.
If it is determined that there is no difference between a measured or determined flow characteristic and an expected flow characteristic during the predetermined time interval, then operations may stop. One or more flow characteristics may be measured and compared to respective expected flow characteristics in one or more subsequent predetermined time intervals during the dispense of the beverage forming ingredient. In this regard, the monitoring of the beverage forming ingredient may continue during one or more subsequent predetermined time intervals and the beverage forming ingredient may be monitored during the course of its pumping and dispense.
If, however, it is determined that there is a difference between a measured or determined flow characteristic and an expected flow characteristic during the predetermined time interval, then processing may move to block 720.
In block 720, a determination may be made as to whether the flow rate of the beverage forming ingredient may be adjusted to compensate for the determined difference. In other words, a determination may be made as to whether the flow rate of the beverage forming ingredient may be increased or decreased in order to compensate for the determined difference. For example, if a measured flow rate for the beverage forming ingredient for the predetermined time interval is approximately 0.8 ounces per second and the expected flow rate for the beverage forming ingredient is approximately one (1) ounce per second, then a determination may be made as to whether the flow rate of the beverage forming ingredient may be adjusted to compensate for the determined difference. The adjustment of the flow rate may be limited by one or more threshold values associated with the flow rate and/or the pumping of the beverage forming ingredient. For example, a maximum flow rate or pumping rate may be associated with the beverage forming ingredient. If the flow rate cannot be adjusted to satisfy the one or more threshold values, then it may be determined that the flow rate cannot be adjusted to compensate for the determined difference. For example, if the measured flow rate is greater than the maximum flow rate and the flow rate cannot be adjusted to be less than the maximum flow rate, such as in a situation in which a valve or pump has malfunctioned, then it may be determined that the flow rate cannot be properly adjusted. As another example, if the measured flow rate is less than the expected flow rate and the flow rate would have to be adjusted to a value that is greater than the maximum flow rate in order to compensate for the difference, then it may be determined that the flow rate cannot be properly adjusted. Such a situation may occur, for example, when a beverage forming ingredient package, such as 114, from which the beverage forming ingredient is supplied is empty or essentially empty. Such a situation may also occur if at least a portion of the pumping technology is not operating properly.
If it is determined that the flow rate of the beverage forming ingredient may be adjusted to compensate for the difference in the measured flow rate and the expected flow rate, then processing may move to block 725. However, if it is determined that the flow rate of the beverage forming ingredient may not be adjusted to compensate for the difference in the measured flow rate and the expected flow rate, then processing may move to block 730.
In block 725, the flow rate of the beverage forming ingredient may be adjusted in order to compensate for the difference between the measured flow rate and the expected flow rate. In this regard, the flow rate may be increased or decreased in order to compensate for the difference.
For example, if the measured flow rate of the beverage forming ingredient is approximately 0.8 ounces per second and the expected flow rate is approximately one (1) ounce per second, then the flow rate of the beverage forming ingredient may be increased to compensate for the deficient dispense of the beverage forming ingredient during the predetermined time interval. The adjustment to the flow rate may result in the flow rate being a flow rate that is different from the expected flow rate. Using the current example, the flow rate of the beverage forming ingredient may be increased to approximately 1.2 ounces per second in order to compensate for the deficient dispense of the beverage forming ingredient during the predetermined time interval. Accordingly, during the next predetermined time interval, the flow rate of the beverage forming ingredient to be dispensed may be approximately equal to the expected flow rate plus the flow rate to compensate for the past deficiency. In certain embodiments of the invention, the expected flow rate may also be adjusted or updated as desired.
In one embodiment of the invention, the flow rate of the beverage forming ingredient may continually be adjusted in order to pump and dispense a precise amount of the beverage forming ingredient for the selected beverage. Additionally, information associated with one or more previous adjustments that have been made to the flow rate may be stored in an appropriate memory, and the information associated with the previous adjustments may be utilized in determining whether an adjustment should be made to the flow rate. Using the example above, if the flow rate for one predetermined time interval has been adjusted to approximately 1.2 ounces per second and the expected flow rate for the predetermined time interval and the next predetermined time period is approximately one (1) ounce per second, then it may be determined that the flow rate for the one predetermined time interval is greater than the expected flow rate for the time interval (1.2-1). Accordingly, the flow rate may be adjusted to compensate for the difference. However, the information associated with the previous adjustment may be utilized to determine that amount of the adjustment, if any, that will be made. In this example, because the adjustment to a flow rate of approximately 1.2 ounces per second was made to compensate for a previous flow rate of approximately 0.8 ounces per second, it may be determined that the flow rate should only be adjusted to approximately 1.0 ounces per second for the next predetermined time interval. If no information associated with previous adjustment is utilized, then the flow rate may be adjusted to approximately 0.8 ounces per second moving forward.
Although the adjustments to the flow rate in block 725 are described with reference to measured flow rates, in certain embodiments, the adjustments to the flow rate may be determined based on a comparison of a measured volume of dispensed beverage forming ingredient to an expected volume of dispensed beverage forming ingredient.
One or more components that monitor the dispense and/or pumping of a beverage forming ingredient, such as, a control node 305 and/or a central controller 105, may be responsible for pumping and/or dispensing the beverage forming ingredient within acceptable parameters for pumping and/or dispense. For example, the beverage forming ingredient may be monitored in order to determine whether the beverage forming ingredient is being pumped and/or dispensed within an acceptable range for pumping or dispense. In the event that a beverage forming ingredient cannot be pumped or dispensed within an acceptable range, then the flow rate of the beverage forming ingredient and/or the flow rates of one or more other beverage forming ingredients for the selected beverage may be adjusted as desired. For example, if a beverage forming ingredient is unable to be pumped at a target or expected flow rate during a predetermined time interval, then the flow rate of the beverage forming ingredient and/or the flow rates of the other beverage forming ingredients for the selected beverage may be adjusted. As an example, if the beverage forming ingredient is being pumped at a flow rate that is lower than an expected flow rate and the flow rate of the beverage forming ingredient cannot be adjusted, then the flow rates of the other beverage forming ingredients for the selected beverage may be decreased in order to accurately pump and dispense the selected beverage. The optional adjustment of one or more other beverage forming ingredients is illustrated in optional block 727.
According to one embodiment of the invention, the adjustment of the flow rate of one or more beverage forming ingredients may be based at least in part on a total accumulated dispense volume for a selected beverage that is being pumped and/or dispensed. For example, after a predetermined period of time, such as 50 ms, a total accumulated dispense volume for a selected beverage may be determined. The total accumulated dispense volume may be determined based at least in part on the total amount or volume that is dispensed for the selected beverage for each of the ingredients of the selected beverage. The total accumulated dispense volume may be utilized to adjust the flow rates of one or more of the beverage forming ingredients for the selected beverage. The determination of the total accumulated dispense volume may be made by a central controller, such as controller 105, and communicated to the control nodes associated with the beverage forming ingredients of the selected beverage, such as nodes 305A-N. The total accumulated dispense volume may then be utilized to adjust the flow rate at which the beverage forming ingredient is pumped and/or dispensed. For example, if a beverage forming ingredient is not being pumped at a desired flow rate, then the determined total accumulated dispense volume may reflect the disparate flow rate. The determined total accumulated dispense volume may then be utilized by an appropriate control device, such as controller 105 or control nodes 305A-N, to adjust the flow rates of one or more other beverage forming ingredients of the selected beverage. For example, if during the dispense of a selected beverage, approximately 0.2 ounces of the selected beverage should have been dispensed at a given point of time but only 0.15 ounces of the selected beverage has been dispensed at the given point of time because one of the beverage forming ingredients is not being dispensed properly, then the flow rates of the other beverage forming ingredients may be adjusted. For each of the other beverage forming ingredients, a determination may be made that a greater amount of the beverage forming ingredient has been pumped and/or dispensed than that specified in the recipe for the selected beverage, and the pumping of the beverage forming ingredient may be dynamically adjusted in accordance with the determination.
The total accumulated dispense volume may then be updated periodically during the dispense of the selected beverage as desired. For example, the total accumulated dispense volume may be updated every 50 ms.
According to another embodiment of the invention, the adjustment of the flow rate of one or more beverage forming ingredients may be based at least in part on an adjustment to the flow rate of the selected beverage. For example, if a beverage forming ingredient cannot be pumped and/or dispensed at an expected flow rate, then the flow rate of the selected beverage may be adjusted. The adjustment to the flow rate of the selected beverage may take the actual flow rate of the beverage forming ingredient that cannot be pumped and/or dispensed at an expected flow rate into account. For example, if the expected flow rate of the beverage forming ingredient is approximately 0.5 ounces per second but the beverage forming ingredient can only be pumped and/or dispensed at a flow rate of approximately 0.3 ounces per second, then the flow rate of the selected beverage may be adjusted based at least in part on the actual flow rate of approximately 0.3 ounces per second for the beverage forming ingredient. The flow rate of the selected beverage may be adjusted so that the other beverage forming ingredients are pumped and/or dispensed in accordance with the recipe for the selected beverage. In the example above, the flow rate of the selected beverage may be reduced to account for the actual flow rate of approximately 0.3 ounces per second for the one beverage forming ingredient, and the flow rates of the other beverage forming ingredients of the selected beverage may be reduced in accordance with the recipe for the selected beverage.
In block 730, one or more control actions may be implemented if the flow rate of the beverage forming ingredient may not be adjusted to compensate for the determined difference between a measured or determined flow characteristic and an expected flow characteristic. A wide variety of control actions may be taken as desired in embodiments of the invention. Examples of control actions that may be taken include, but are not limited to, ceasing the dispense of a beverage forming ingredient, limiting the dispense of a beverage forming ingredient, dispensing a beverage at a reduced speed or flow rate, outputting an appropriate error message, communicating an appropriate error message over a network, and/or switching to a second beverage forming ingredient package, such as 114, or beverage forming ingredient source to complete the dispense of the beverage forming ingredient.
One possible control action is ceasing the dispense of the beverage forming ingredient. If the beverage forming ingredient is not being dispensed properly, then a low quality beverage may be dispensed by a beverage forming dispenser 100. For example, a COCA-COLA™ beverage may be dispensed that does not have an appropriate amount of COCA-COLA™ syrup, leading to a beverage that is either too strong or too weak. Such a dispense may lead to customer dissatisfaction. Additionally, if continued dispense of the COCA-COLA™ beverage is allowed, then multiple beverages may be dispensed that lead to customer dissatisfaction. By ceasing the dispense of the beverage forming ingredient, then the dispense of an inadequate COCA-COLA™ beverage may be limited or prevented, thereby limited and/or limiting customer dissatisfaction. Additionally, by ceasing the dispense of the beverage forming ingredient, a customer may be notified of the inadequate dispense of the selected beverage and the inadequate dispense may be rectified. For example, one or more new beverage forming ingredient package, such as 114, may be inserted into the ingredient matrix, allowing the COCA-COLA™ beverage to be dispensed properly. As another example, the beverage forming dispenser 100 or components of the beverage forming dispenser 100 may be reset or default values may be restored by a customer or a technician. As another example, a service technician may be notified by the customer as a result of the control action.
In one embodiment of the invention, one or more tolerance settings may be utilized in conjunction with implementing a control action. In the example of a control action in which the dispense of a beverage forming ingredient is ceased, one or more tolerance settings may permit the dispense of the selected beverage to be completed prior to limiting the dispense of a beverage forming ingredient. For example, if the dispense of the selected beverage is approximately equal to or greater than a threshold completion value, such as 90 percent, then the dispense of the selected beverage may be allowed to be completed. Following the completion of the dispense, further dispenses of the beverage forming ingredient may be limited, prevented, or ceased.
Another possible control action is limiting the dispense of the beverage forming ingredient. For example, the dispense of the beverage forming ingredient may be prevented from an ingredient matrix location or beverage forming ingredient package associated with the control action.
Another possible control action is to dispense the beverage forming ingredient by utilizing another source of the beverage forming ingredient if another source is available. For example, the dispense of the beverage forming ingredient may be implemented by utilizing a second beverage forming ingredient package containing the beverage forming ingredient that is connected to or associated with an ingredient matrix, such as 112.
Another possible control action is to dispense the beverage at a reduced speed or flow rate. For example, if a beverage forming ingredient is not capable of being dispensed at a desired flow rate, a determination may be made as to a flow rate at which the beverage forming ingredient may be dispensed. The dispense of the beverage may then be implemented at a reduced flow rate based at least in part on the determination. Alternatively, a determination may be made as to whether the beverage forming ingredient may be dispensed in accordance with a predetermined minimum flow rate. If it is determined that the beverage forming ingredient may be dispensed in accordance with the predetermined minimum flow rate, then the dispense of the beverage may be implemented utilizing the predetermined minimum flow rate.
Another possible control action is to output and/or communicate an appropriate error message associated with the determination that the flow rate of the beverage forming ingredient cannot be adjusted. For example, an error message or error indication may be output utilizing one or more appropriate output devices associated with a controller, such as 105, or a control node, such as 305. Many different types of error messages or indications may be utilized as desired in embodiments of the invention such as, text messages that are output utilizing a suitable display and/or LED indicators.
One or more error messages may also be communicated in association with the determination that the flow rate of the beverage forming ingredient cannot be adjusted. The one or more error messages may be communicated via an appropriate network. The one or more error messages may be communicated to other components of the beverage forming dispenser 100 and/or to remote devices. For example, a control node, such as 305 may communicate an error message to a central controller, such as 105. As another example, a control node 305 and/or a central controller 105 may communicate an error messages to a remote device, such as, a server, processing center, customer support center, technical support center and/or a personal computer associated with a maintenance supervisor, a customer, a supervisor of the customer, or a technician associated with the beverage forming dispenser 100. The error messages may be communicated in any suitable form, for example, by e-mail over a LAN or WAN (e.g., the Internet).
The example of a method for monitoring the dispense of a beverage forming ingredient may end following either block 715 or block 730.
Additionally, at least one program storage device readable by a machine, tangibly embodying at least one program or set of instructions executable by the machine to perform the capabilities of the embodiment of the invention can be provided.
The flow diagrams depicted herein are examples. There may be many variations to these diagrams or the steps (or operations) described therein without departing from the scope of the invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted or modified. All of these variations are considered a part of the claimed invention.
