The present application and the resultant patent relate generally to beverage dispensing systems and more particularly relate to an automated beverage dispensing system with ice and beverage dispensing stations using a weight sensor for fast and efficient service.
Beverage dispensers traditionally combine a diluent such as water with a beverage base such as a syrup and the like. These beverage bases generally have a dilution or a reconstitution ratio of about three to one (3:1) to about six to one (6:1). The beverage bases usually come in large bag-in-box containers that require significant amounts of storage space and may need to be refrigerated. These storage requirements often necessitate the need to position these bag-in-box containers away from the dispenser in a backroom with a long supply line. Each bag-in-box container usually only holds a beverage base for a single type or flavor of beverage such that multiple bag-in-box containers may be required to provide the consumer with a variety of beverage options.
Resent improvements in beverage dispensing technology have focused on the use of micro-ingredients. With micro-ingredients, the traditional beverage bases may be separated into their constituent parts at much higher reconstitution ratios. These micro-ingredients then may be stored in much smaller packages and stored closer to, adjacent to, or within the beverage dispenser itself. The beverage dispenser preferably may provide the consumer with multiple beverage options as well as the ability to customize his or her beverage as desired.
Beverage dispensers incorporating such highly concentrated micro-ingredients have proven to be highly popular with consumers. One example of the use of such micro-ingredients is shown in commonly owned U.S. Pat. No. 7,757,896 B2 to Carpenter, et al., entitled “BEVERAGE DISPENSING SYSTEM.” U.S. Pat. No. 7,757,896 B2 is incorporated herein by reference herein in full. Likewise, such micro-ingredient technology is incorporated in the highly popular “FREESTYLE®” refrigerated beverage dispensing units provided by The Coca-Cola Company of Atlanta, Ga. The “FREESTYLE®” refrigerated beverage dispensing units can dispense over 125 brands without the need for extensive storage space.
There is now a desire to incorporate such micro-ingredient technology for behind the counter or crew serve applications in venues such as quick service restaurants and the like. The use of such micro-ingredient technology would allow the venue to offer dozens of different beverages without significant storage requirements in a fast and efficient manner.
The present application and the resultant patent thus provide an automated beverage dispenser for dispensing a beverage and ice into a cup. The automated beverage dispenser may include an ice dispensing station with an ice auger and a weight sensor, a beverage dispensing station, and a control device. The control device instructs the ice auger to fill the cup with a predetermined amount of ice and instructs the beverage dispensing station to fill the cup with a predetermined amount of the beverage in response to a weight of the cup as determined by the weight sensor.
The present application and the resultant patent further provide a method of filling a cup with ice and a beverage in an automated beverage dispenser. The method may include the steps of positioning the cup about a load cell, weighing the cup while filling the cup with a predetermined amount of ice, and filling the cup with a predetermined amount of the beverage based upon the weight of the cup and the ice as determined by the load cell.
The present application and the resultant patent further provide an automated beverage dispenser for dispensing a beverage and ice into a cup. The automated beverage dispenser may include a dispensing conveyor, a load cell positioned about the dispensing conveyor, an ice auger positioned about the dispensing conveyor, a dispensing nozzle positioned about the dispensing conveyor, and a control device. The control device instructs the ice auger to fill the cup with a predetermined volume of ice and instructs the dispensing nozzle to fill the cup with a predetermined volume of the beverage in response to a weight of cup as determined by the load cell.
These and other features and improvements of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.
Referring now to the drawings, in which like numerals refer to like elements throughout the several views,
Generally described, the beverage dispensing system 100 may include a cup placement station 120 with a number of cups 125, an ice dispensing station 130, a beverage dispensing station 140, a cup lidding and removal station 150 with a number of lids 155, and a printing station 160. Other stations 110 and other components may be used herein. Some or all of the stations 110 may be positioned about a dispensing conveyor 170. An outgoing staging conveyor 180 also may be used. Each of these stations 110 and the other components used herein may be in communications with a control device 190. The control device 190 may be a conventional micro-computer and the like capable of executing programmable commands. The control device 190 may be internal to or removed from the beverage dispensing system 100. The control device 190 may be responsive to instructions or requests from a number of input devices 200. The input devices 200 may be any type of user interface, such as conventional cash registers, order monitoring systems (bump screen), touch screen, and similar types of order input devices typically found in quick service restaurants and other types of retail establishments. Instructions or requests may be entered by a crew member, a consumer, or anyone else. Any number of input devices 200 may be used herein. Other components and other configurations may be used herein.
The cups 125 may be transported from station to station herein via the dispensing conveyor 170. The dispensing conveyor 170 may be a conventional timing belt or other types of transport devices. A number of cup holders 210 may be positioned on the dispensing conveyor 170. The cup holders 210 may include a number of walls 220 extending in a direction perpendicular to that of the advance of the dispensing conveyor 170. The walls 220 may be spaced apart so as to accommodate cups 125 of varying sizes. As will be described in more detail below, the walls 220 may have a number of slots 230 therein. Advancement of the dispensing conveyor 170 may be controlled by the control device 190. Multiple dispensing conveyors 170 may be used herein. Other components and other configurations may be used herein.
The cup placement station 120 may include a cup storage turret 240 or other type of cup storage device. The cup storage turret 240 may include a number of cup sleeves 250. The cup sleeves 250 may be sized for differently sized cups 125. Any number and any size of the cup sleeves 250 may be used herein with any number or any size of the cups 125. The cup sleeves 250 may rotate about a turret pin 260 in a conventional manner in communication with the control device 190. A release mechanism 270 may be positioned about the cup sleeves 250 so as to release an appropriately sized cup 125 into one of the cup holders 210 located in the cup placement station 120 on the dispensing conveyor 170 as instructed by the control device 190. Multiple cup storage turrets 240 may be used herein. Other components and other configurations may be used herein.
The ice delivery tube 310 may extend over the dispensing conveyer 170 so as to dispense ice 290 into a cup 125 located in the cup dispensing station 130. The auger 320 drives the ice 290 through the ice delivery tube 310 and into the cup 225. The flow of ice 290 is controlled by the auger 320 and the auger motor 330 in communication with the control device 190. The amount of ice dispensed may be determined by a combination of the rotational rate of the auger 320 with respect to time. The control device 190 may have a look-up table or other types of data structures and associated software so as to provide a targeted, predetermined amount of the ice 290 for a given cup size. Moreover, modifications also may be requested, i.e., no ice, light ice, normal ice, or extra ice as directed by the input devices 200. The auger motor 330 may dynamically adjust the torque on the auger 320 so as to overcome ice jams and blockages therein while maintaining the correct rotational rate. The ice delivery tube 310 and the auger 320 may be removable for cleaning. Other components and other configurations may be used herein.
The ice dispensing station 130 also may include a weight sensor 335. In this example, the weight sensor 335 may be in the form of a load cell 340 although any type of weight sensor 335 may be used. The load cell 340 may be positioned about the dispensing conveyor 170 adjacent to the ice delivery tube 310. The load cell 340 may include a cup interface block 350 with a number of fins 360 extending therefrom. The fins 360 may extend upwardly into the dispensing conveyor 170. The fins 360 may be sized to accommodate the slots 230 in the walls 220 of the cup holders 210. As a cup holder 210 with an empty cup 125 moves into the ice dispensing station 130, the slots 230 slide through the fins 360 of the cup interface block 350. The fins 360 may slightly elevate the empty cup 125. The load cell 340 then may determine the tare weight of the empty cup 125. The load cell 340 subtracts the tare weight of the empty cup 125 as the ice 290 is dispensed therein. The load cell 340 may provide feedback to the control device 190 to ensure that an accurate predetermined volume of the ice 290 is dispensed therein for a given cup size. Likewise, the correct volume ensures that the ice 290 reaches a correct fill height within the cup 125. Other components and other configurations may be used herein.
The micro-ingredients 380, the macro-ingredients 390, and the diluents 400 may be mixed at the dispensing nozzle 370 or elsewhere. Example of suitable dispensing nozzles 370 include those described in commonly owned U.S. Pat. No. 7,866,509 B2 to Ziesel, entitled “DISPENSING NOZZLE ASSEMBLY” and commonly owned U.S. Pat. No. 7,578,415 B2 to Ziesel, et al., entitled “DISPENSING NOZZLE ASSEMBLY.” U.S. Pat. Nos. 7,866,509 B2 and 7,578,415 B2 are incorporated herein by reference in full. Multiple dispensing nozzles 370 may be used herein. Conventional dispensing nozzles with conventional beverage ingredients also may be used herein. Other components and other configurations may be used herein.
The dispense of the beverage 410 from the dispensing nozzle 370 may be controlled by the control device 190. The timing of the dispense may vary with the nature of the beverage 410, the amount of the ice 290 within the cup 125, and other parameters. For example, the control device 190 may determine the target volume of the beverage 410 so as to provide the correct fill level. Specifically, the total volume of the cup contents equals the volume of the beverage plus the volume of ice. If the weight of the ice is known, the volume of the ice may be calculated for each cup size. The total volume of the beverage therein thus may be determined by subtracting the dispensed ice volume from the total target cup contents volume. For example, if at the end of the ice dispensing the load cell 340 detects that too much or too little ice has been dispensed into the cup 125, the control device 190 might adjust the amount of the beverage dispensed via an ice dispensing error amount signal to compensate for any inaccuracy in the ice amount to insure that the cup 125 is filled to the correct fill level, i.e., the adjusted target amount of the beverage 410. Other components and other configurations also may be used herein.
The dispense also may be momentarily paused one or more times so as to accommodate foaming of the beverage therein in the case of a carbonated beverage and the like and then resumed to provide the correct predetermined volume of the beverage therein without spillage. Different beverages 410 may have different foaming characteristics. For example, lemonade (a non-carbonated beverage) may have no foam, a carbonated diet soft drink may have a medium level of foam, and a carbonated soft drink with flavoring may have an extreme level of foam. The same beverage 470 also may foam differently depending on how much ice 290 is in the cup 125. The more ice 290 in the cup 125, the less foam may be created. Cup size also may affect the dispensing parameters. A larger cup 125 with a larger volume of beverage 470 may generate a larger volume of foam as compared to a similar beverage in a smaller cup 125 and may thus require a longer wait time for foam dissipation. A non-foaming beverage such as a lemonade thus may be dispensed in one continuous pour. A medium foaming beverage may be dispensed with an initial partial pour, a wait time for the foam to dissipate, then a final top-off. An extreme foaming beverage may need to be dispensed in three or more pours with a longer wait times in between each pour to allow the foam to dissipate. An extreme foaming beverage also may require time to allow the foam to dissipate after the final top-off before moving the cup 125.
Each beverage 410 may be characterized by the level of foam generated such that the beverage dispensing parameters may be set according to the foam level of the beverage 410, the level of ice 290 in the cup 125, and the size of the cup 125. Beverage dispensing parameters may include but are not limited to: (1) the number of pours; (2) the percent of the volume of the cup 125 filled by the initial pour; (3) waiting time between pours; (4) and waiting time after the last pour before the cup begins moving. Other parameters may be used herein. By setting the beverage parameters properly, a beverage 410 may be poured in a minimum amount of time without foaming-over.
Specifically, each beverage 410 may be assigned a level of foaming. Any number of levels of foaming may be created. For the purposes of example six (6) levels of foaming may be used from “1”: non-foaming, to “6”: extreme-foaming. The level of foaming may be included in a master recipe data base in the control device 190.
The cup lidding and removal station 150 also may include one or more lid stacks 450. The lid stacks 450 may have a stack of the lids 155 therein. The lid stacks 450 may include a number of posts 460 to support the lids 155 therein while providing access thereto. Although three (3) posts 460 are shown, any number of the posts 460 may be used. The lid stack 460 also may include one or more springs 470 positioned underneath the lids 155. The springs 470 may allow a reasonable degree of over travel. Any number of the lid stacks 450 may be used. Specifically, the lid stacks 450 with differently sized lids 155 may be positioned adjacent to each other. Other components and other configurations may be used herein.
The cup lidding and removal station 150 may include a lidding mechanism 480. The lidding mechanism 480 may include a base 490 with a number of spring clips lid retention members 495 extending therefrom. In this example, the lid retention members 495 may be in the form of a number of spring clips 500. Each of the spring clips 500 may include a base portion 510, a narrowing attachment portion 520, and an expanding centering portion 530. The spring clips 500 may be made out of any type of flexible material with a sufficient amount of memory so as to resist permanent deformation while accommodating lids 155 of differing sizes. Any number of the spring clips 500 may be used herein. The spring clips 500 may be adapted for use with lids 155 having a top portion 540 and an indented bottom portion 550. Other shapes and other types of lid retention members 495 may be used herein. A proximity switch 555 and the like may be positioned about the base 490 between the spring clips 500. The proximity switch 555 may be in the form of a contact switch 560. The contact switch 560 may be in communication with the control device 190. Other components and other configurations may be used herein.
The cup lidding and removal station 150 also includes a positioning device 565 for maneuvering the lidding mechanism 480. The positioning device 565 may include a vertical linear actuator 570 and a second horizontal linear actuator 580. The actuators 570, 580 may be in communication with the lidding mechanism 480. The actuators 570, 580 may be any type of movement device that provides substantially vertical and/or horizontal motion. The base 490 of the lidding mechanism 480 may be attached to the vertical linear actuator 570 for vertical motion while the vertical linear actuator 570 may be attached to the second horizontal liner actuator 580 for horizontal motion. The second horizontal linear actuator 580 may be positioned above the first horizontal linear actuator 440. Other components and other configurations may be used herein.
When the dispensing conveyor 170 delivers a full cup 125 to the griper mechanism 420, the griper jaws 430 engage and center the cup 125 therein with respect to the cup lidding mechanism 480. At any point in the dispensing process, the lidding mechanism 480 may be maneuvered by the second horizontal linear actuator 580 and the vertical linear actuator 570 to the lid stack 450 with the appropriately sized lids 155 therein. As is shown in
If the lid 155 is successfully engaged as indicated by continued actuation of the contact switch 560, the vertical linear actuator 570 and the second horizontal linear actuator 580 of the positioning device 565 may maneuver the lidding mechanism 480 over the cup 125 within the gripper mechanism 420.
Once the lidding mechanism 480 is clear of the cup 125, the first horizontal linear actuator 440 may move the gripper mechanism 420 with the cup 125 to the staging conveyor 180. The gripper jaws 430 of the gripper mechanism 420 may release the cup 125 such that the cup 125 may move out of the gripper jaws 430 as the staging conveyor 180 advances. A number of dispensed, lidded, and identified beverages may be stored on the staging conveyor 180 for order fulfillment. The staging conveyor 180 may advance by one cup pitch each time a finished beverage is delivered to the staging conveyor 180 so as to efficiently space the staged beverages. The staging conveyor 180 may advance by more than one cup pitch to create a relatively larger space between cups 125 to segregate cups 125 from one customer order to cups 125 from a subsequent order. There may be a sensor 640 at the far end of the staging conveyor 180 to detect when the staging conveyor 180 is full to prevent cups 125 from falling off of the end of the staging conveyor 180. The overall cycle then may be repeated. Other components and other configurations may be used herein.
After the lidding mechanism 480 attaches the lid 155 to the cup 125 as described above, the vertical linear actuator 570 raises the lidding mechanism 480 to a predetermined height so as to accommodate the printing head 590. As the first horizontal linear actuator 440 and the gripper mechanism 420 move the cup 125 towards the staging conveyor 180, the lid 155 may pass underneath the printing head 590. The printing head 590 then prints one or more messages 610 thereon. The message 610 may include a brand or other beverage identifier 620 and an order number 625. The message 610 also may include any type of information such as an advertisement, refill information, nutritional information, a coupon, a prize, and the like. Any type of information, designs, or other indicia may be printed thereon.
Although the printing head 590 has been described in terms of being positioned about the lidding mechanism 480, the printing head 590 may be positioned anywhere along the travel path of the lid 155. Further, the printing head 590 also may be positioned so as to print the message 610 on the side or even the bottom of the cup 125. Multiple printing heads 590 may be used herein. Other components and other configurations may be used herein.
The various stations 110 of beverage dispensing system 100 located about the dispensing conveyor 170 and the staging conveyor 180 may be located above a drain pan 650 so that drips and spills may be appropriately routed to a drain 660. The staging conveyor 170 and the dispensing conveyor 180 may be mounted to a deck 670 so as to be removable for cleaning. Moreover, a motor 680 powering the dispensing conveyor 170 may be located above the deck 670 so that drips and spills will not land on the motor 680. The disengagement of the motor 680 from the staging conveyor 170 may be a simple, passive process when the deck 670 is removed for cleaning.
Although the beverage dispensing system 100 has been described in the context of a behind the counter or a crew serve environment, the beverage dispensing system 100 also may be used in a freestanding or customer serve mode. For example,
The beverage dispensing system 100 thus automates the beverage dispensing process. In response to a request for a beverage at the input device 200, the cup placement station 120 selects the appropriately sized cup 125 and places the cup 125 within the cup holder 210 of the dispensing conveyor 170. The dispensing conveyer 170 advances the cup 125 to the ice dispensing station 130. The ice dispensing station 130 dispenses the appropriate predetermined volume of ice 290 therein via feedback from the load cell 340. The dispensing conveyor 170 then advances the cup 126 to the dispensing nozzle 370. The dispensing nozzle 370 fills the cup 125 with the appropriate predetermined volume of the desired beverage 410. The controller 190 also may adjust the amount of the beverage dispensed to compensate for any inaccuracies in the dispensed ice as detected by the load cell 340 so that the proper fill level in the cup 125 may be achieved. The beverage dispensing station 140 may pause during the dispense so as to accommodate foaming. The dispensing conveyor 170 may maneuver the cup 125 to the cup lidding and removal station 150. The gripper mechanism 420 may grab and center the cup 125. The lidding mechanism 480 may be maneuvered by the vertical linear actuator 570 and the second horizontal linear actuator 580 of the positioning device 565 to select and remove the appropriately sized lid 155 from one of the lid stacks 450. The lidding mechanism 480 may be maneuvered so as to attach the lid 155 to the cup 125. The lidding mechanism 480 then may be raised and the cup 125 may begin to maneuver towards the staging conveyor 180 via the first horizontal linear actuator 440. While doing so, the cup 125 passes under the printing head 590 of the printing station 160 such that a message 610 may be printed on the lid 155 or elsewhere.
As described above, the various stations 110 of the beverage dispensing system 100 need not all be used herein together. Likewise, additional stations and additional components also may be used herein. Components may be substituted for other known components that may carry out the function of the components described herein. The beverage dispensing system 100 thus provides a lidded and identified beverage in a fast and efficient manner. Given the high volume of beverages and the large variety that may be produced herein, the use of the brand identifier 620 is helpful to ensure that the consumer receives the correct beverage—particularly with beverages of a similar color. The beverage dispensing system 100 also ensures that the correct amount of ice 290 is added to the beverage 410 so as to limit premature melting with too little ice or an inadequate volume of the beverage 410 therein with too much ice. Other types of additives or other types of ingredients in liquid, solid, or gaseous form also may be added to the cup 125 in additional stations 110. Multiple beverage dispensing systems 100 also may be used herein and may share certain stations 110 or other components.
It should be apparent that the foregoing relates only to certain embodiments of the present application and the resultant patent. Numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
The present application is a non-provisional application claiming priority to U.S. Provisional Patent Application No. 61/603,403, filed on Feb. 27, 2012. U.S. Provisional Patent Application No. 61/603,403 is incorporated herein by reference in full.
