Embodiments disclosed herein are directed to beverage formation systems, which in some embodiments include a beverage preparation machine capable of preparing a beverage with limited or no user intervention. For example, in some embodiments, a user, such as a customer, may place an order for a specific type and size of a beverage, and the beverage preparation machine will position a cup, add ice and various other ingredients, blend the contents directly in the cup, and then present the prepared beverage to the user in a pickup area.
In some embodiments, a robotic arm grips and moves a beverage container among several stations to prepare the beverage. More than one beverage may be prepared simultaneously in some embodiments. For example, while a first cup is having its contents blended by a blending station, a second cup may be receiving shaved ice at an ice station. Such an arrangement may permit a set of beverages to be prepared more quickly than serial preparation. In some embodiments, simultaneous preparation of multiple beverages with a single machine may allow for a higher utilization rate for various components of the machine.
Multiple robotic arms may be used in some embodiments, or a single robotic arm may be used to move the beverage containers through the beverage preparation process.
According to one aspect of the disclosure, a weight sensor may be incorporated within the robotic arm. In some cases, such an arrangement can facilitate control of the addition of ingredients to the beverage container. According to another aspect of the disclosure, the robotic arm could also include a volume sensor that measures an amount of liquid and/or ice inside the container.
According to another aspect of the disclosure, a rotary cup dispenser may be employed. The dispenser may release one cup at a time from a stack of nested cups by rotating the internal threads of an indexing wheel between cup rims.
The inventive concepts described herein can be implemented in any of numerous ways, and are not limited to any particular implementation techniques. Thus, while examples of specific implementation techniques are described below, it should be appreciated that the examples are provided merely for purposes of illustration, and that other implementations are possible. Any of the subassemblies described herein may be used in other machines and in any suitable combination.
Turning to the figures,

Under the control of controller 17, the container dispenser 16 is configured to separate a single container 28 from a stack of containers and deposit the container to one of two container drop positions (see
As will be discussed in greater detail below, the container movement and positioning assembly 18 includes a robotic arm which includes a gripper to grasp the container 28, and moves the container within the machine 10 among the different stations. The cubed ice dispenser 20 deposits cubed ice into the container 28 based on one or more options selected by the user. The ingredient dispenser 22 is configured to dispense one or more ingredients into the container 28 based on the one or more options selected by the user. The shaved ice dispenser and blending assembly 24 is configured to dispense shaved ice into the container and to blend the ingredients and shaved ice within the container 28. The container delivery assembly 26 is configured to present a prepared drink to the user. For purposes herein, the ice and water are considered to be an ingredient.
During beverage preparation, the container dispenser 16 deposits a container 28 to one of two positions 30, 32 associated with the container movement and positioning assembly 18. In one mode of operation, in which the beverage preparation machine 10 prepares an iced beverage, the container 28 is moved by the container movement and positioning assembly 18 to a cubed ice drop position 34 in which the cubed ice dispenser 20 deposits cubed ice into the container. Next, the container 28 is moved by the container movement and positioning assembly 18 to one of two positions 36, 38 associated with the ingredient dispenser 22 to dispense flavored product or products into the container. The container is moved by the container movement and positioning assembly 18 to the container delivery assembly 26 at one of three positions 44, 46, 48 in which the container is positioned to be accessible by the user. A user who retrieves the prepared beverage does not necessarily have to be the same user who input a beverage selection into the beverage preparation machine.
In another mode of operation, in which the beverage preparation machine 10 prepares a blended frozen beverage, the container 28 is moved by the container movement and positioning assembly 18 to one of two positions 36, 38 associated with the ingredient dispenser 22 to dispense flavored product or products into the container. Next, the container 28 is moved by the container movement and positioning assembly 18 to one of two positions 40, 42 associated with the shaved ice dispenser and blending assembly 24 to deposit shaved ice into the container and to blend the product(s) and shaved ice within the container. Once blended, the container 28 is moved by the container movement and positioning assembly 18 to the container delivery assembly 26 at one of the three positions 44, 46, 48 in which the container is positioned to be accessible by the user.
The controller may control the preparation of multiple beverages at the same time. For example the controller may instruct the robotic arm to move a first container from an ingredient addition station to a blending station, and while the first container is having its contents blended, the robotic arm may be moving a second container from a processing station to a serving area Before the blending of the first container has been completed, the robotic arm may move a third container to an ingredient addition station. In this manner, the robotic arm may be nearly continuously moving while multiple drinks are being prepared.

For each of tubes 64a, 64b, the containers are prevented from sliding out of the second, open end of the tube by one of two rotary container dispensers 70a, 70b. For example, rotary container dispenser 70a includes an internal screw thread which releasably engages a rim of the lowermost container within the stack of containers. As shown, for tube 64a, the rotary container dispenser 70a is positioned on an upper surface of the support plate 62 (
Each rotary container dispenser 70a, 70b includes a gear assembly 72a, 72b driven by an electric motor (e.g., motor 74b for gear assembly 72b) mounted on the support plate 62. Each gear assembly 72a, 72b is configured to index a single container 28 within the tube 64a, 64b to release the container. Once released, the container 28 travels through a bottom portion of the tube 64a, 64b to a container yoke 76a, 76b positioned underneath the bottom open end 68a, 68b of the tube. For each tube 64a, 64b, the container dispenser 16 further includes a refill detection switch 78a, 78b to detect whether the supply of containers needs to be refilled. The container dispenser 16 further includes a drop detection switch 80a, 80b to detect the presence of the container 28 within the container yoke 76a, 76b. Any suitable sensor may be used to detect the presence of the container to confirm that the container has been placed.
Each container yoke 76a, 76b is sized to receive and support the container deposited by its respective tube 64a, 64b. As shown, each container yoke 76a, 76b includes a curved structure having an inwardly projecting rim 82a, 82b sized to engage the rim of the container 28. The arrangement is such that when the lowermost container is lowered to the container yoke 76a, 76b, the rotary container dispenser 70a, 70b engages a rim of a next lowermost container to maintain that container in a supported position, thereby supporting the entire stack of containers within the tube 64a, 64b. In another embodiment, each container yoke 76a, 76b may be designed to accommodate containers of different sizes. For example, each container yoke 76a, 76b may include spring-loaded fingers which are configured to grasp containers having a variety of different diameters. During the initiation of a dispense operation, the container dispenser 16, under the control of the controller, dispenses a single container 28, e.g., a disposable cup, into the container yoke 76a, 76b of the container dispenser. As shown in
Some embodiments of a rotary container dispenser include a rotating ring 202 shown in
This rotary dispenser may be used in other systems or machines, and is not limited to use with beverage preparation machines described herein.
According to some embodiments, container dispensers are used which are not rotary dispensers. In still other embodiments, controlled dispensers are not used; instead, a user manually places cup at an initial station.

In some embodiments, the gripper 85 includes a pair of fingers 88, 90, which are moved toward and away from one another and radially in and out with respect to the central axis A by a motor 92 linked to the controller. The fingers 88, 90 grip a body of the container 28 with a force sufficient to support and move the container and its contents. During operation, for example when moving the container 28 from the container dispenser 16 to the cubed and shaved ice dispensing assembly 20, the fingers 88, 90 are moved away from each other and the robotic arm is extended from a retracted position to an extended position toward the container. Once the fingers surround the container 28, the fingers 88, 90 move toward one other to grip the container. The rotor assembly 86 then rotates the robotic arm 84 from the existing station, e.g., the container dispenser 16, to the next station, e.g., the cubed and shaved ice dispensing assembly 20. This process is repeated to move the container 28 from station-to-station until the beverage is prepared.

In some embodiments, assembly 20 may be capable of providing shaved ice to the beverage container 28. The assembly may include an ice shaver 96 which is positioned underneath the ice hopper 94 to deposit shaved ice into the container through an exit port 98. As shown, cubed ice is deposited into the ice shaver 96 through an opening 104 formed in the bin 100. The ice hopper 94 and the ice shaver 96 may be indexed to provide precise amounts of shaved ice to the container 28 in some embodiments. Once ice reaches the ice shaver 96, the ice shaver shaves the ice and deposits the ice in the container 28.
As shown in
The arrangement is such that the cubed and shaved ice dispensing assembly 20 is manipulated under the control of the controller to deposit cubed ice into the container 28 at the ice drop position 34 or deposit shaved ice into the container when the container reaches the shaved ice dispensing and blending assembly 24 at the two positions 40, 42 associated with the assembly 24. As with the amount of flavoring dispensed into the container 28, the amount of cubed ice or shaved ice deposited within the container may be selected based on the size of the container and the types of flavors added to the container. In some embodiments, an amount of cubed ice or shaved ice may be determined by an amount of time the cubed and shaved ice dispensing assembly 20 operates. In another embodiment, a weigh scale may be provided to measure the weight of the ice dispensed into the container 28 in a manner described below. When not operating, ice is retained within the ice hopper 94 by the rotatable blades 106 of the ice shaver.
As described above, the ingredient dispenser 22 is configured to dispense a quantity of a flavored product from among a variety of flavored products into the container 28. In some embodiments, the ingredient dispenser 22 is controlled by the controller. The ingredient dispenser 22 may include a pump that is supported by the housing 12 and several tubes or lines that are coupled to the pump to deliver flavored product to a nozzle. In a certain embodiment, containers of flavored fluids or products may be provided at a remote location and connected to one or more nozzles via the inlet connectors 58. In another embodiment, the containers of flavored fluids or products may be disposed within the machine 10 or within a cooling unit upon which the machine 10 rests. The flavor products may be stored in containers, with sensors being provided to indicate when a certain container is empty.

As shown, an ice chute 120 may be positioned to add ice to the container 28 with the container positioned in the blend position - without movement of the blender drive assembly or the chute. For example, the ice chute may be connected to the blender drive assembly such that ice exits an exit port 121 through which the blender blades 118 also exit. In this manner, the beverage preparation machine can direct ice (shaved, cubed, or other) from an ice source, such as the ice shaver 96, into the container 28 simultaneous with the operation of a blending step (or other processing step).
The shaved ice dispensing and blending assembly 24 further includes a first motor 122 coupled to a drive shaft 124 that supports the blades 118. The first motor 122 is configured to rotate the drive shaft 124 at a speed to blend the container contents with the blades 118. The shaved ice dispensing and blending assembly 24 may further include a second motor 126 coupled to a carriage 128 to move the drive shaft 124 (and therefore the blades 118) up and down within the container 28.
The entire assembly shown above the container in
With this arrangement, ice (whether cubed, shaved, or other) may be added to the container simultaneously with blending of the container contents. In some embodiments, instead of blending, other processing may take place simultaneously with the addition of ice.
The shaved ice dispensing and blending assembly 24 may also include a nozzle disposed within the drive shaft 124 of the blender drive assembly 116. In one embodiment, nozzles are connected to a water supply 130 provided within the housing 12 to perform a rinse and clean operation within the shaved ice dispensing and blending assembly 24, and a drain pan (see
The water used to rinse the drive shaft 124 and the blades 118 of the blender drive assembly 116 drains through the drain port 60 provided in the housing. In some embodiments, the nozzles may be positioned inside a base of the blender drive assembly 116 as a separate assembly. While water is being applied to the drive shaft 124 and blades 118 for rinsing, the blades may simultaneously be spun to improve rinsing effectiveness.
The beverage preparation machine may be configured to perform the rinse and clean operation described above automatically. For example, the controller 17 could control the nozzle to perform the rinse and clean operation every time after a beverage is prepared. Alternatively, the controller 17 could control the nozzle to perform the rinse and clean operation after a predetermined number (merely by way of example, five) of beverage preparation. Alternatively, the controller 17 could control the nozzle to perform the rinse and clean operation after a predetermined amount of time, such as every 24 hours.

Each container holder 132 includes a container nest 134, which is designed to receive and support a container 28, and a container platform cover 136, which is designed to support the container nest and secured to the housing by a magnet.
Each container holder may include a weigh scale, which, in some embodiments, includes a load cell mount 138 and a load cell printed circuit board 140 that is coupled to the controller. Each weigh scale may be configured to support and sense a weight of the container 28 and the contents therein. The arrangement may be such that when a container 28 is placed on the container holder 132, the weigh scale is able to weigh the container to determine whether an appropriate amount of ice (cubed or shaved) and/or other ingredients have been deposited into the container. Each container holder could also include a volume sensor that measures an amount of liquid and/or ice inside the container.
In some embodiments, the controller is configured to control the operations of the cubed and shaved ice dispensing assembly 20 and the ingredient dispenser 22 through feedback provided by the weigh scale. For example, the ingredient dispenser may add an ingredient until the weigh scale indicates a pre-selected weight. In some cases, the pre-selected weight may be set as a total weight of the container and its contents as compared to a starting weight of zero. In other embodiments, the pre-selected weight may be based on the starting weight of the container and its contents when the container arrived at the ingredient dispenser. That is, the container may arrive with a weight of 250 grams, and an ingredient may be added until the weight is 275 grams for an ingredient addition of 25 grams. If the container arrived at the ingredient dispenser with a weight of 247 grams, the preselected weight at which to stop adding the ingredient may be set at 272 grams.
The weigh scale is coupled to the controller and measurements may be displayed on the control panel or touch screen 14 to inform the user that the prepared beverage is ready or that an incorrect amount of shaved or cubed ice or other ingredient has been added to the container. The weigh scale may measure weight or mass and be considered a weigh scale or other type of weight sensor.
In some embodiments, the container delivery assembly includes a forwardly projecting platform 142 (see
In some embodiments, one, some, or all of the doors may include a lock to prevent the doors from being opened by a user. For example, a solenoid lock may be used to keep the door locked until a controller unlocks the door for beverage delivery.
While some embodiments illustrated herein show a radial arrangement where a centrally located robotic arm and gripper moves containers between container holders or stations that are radially positioned about a pivot axis of the robotic arm, other arrangements are contemplated. For example, in some embodiments, container holders may be positioned linearly and a gripper moves along a linear drive to pick and place containers. In other embodiments, containers may be held on a carousel, and the carousel may be rotated to position containers under different stations, such as ingredient addition stations and beverage processing stations. In still further embodiments, containers may travel on a conveyor (whether linear or otherwise) between various stations.
FIG, 32 illustrates a control algorithm for controlling the beverage preparation machine to produced an iced beverage according to one embodiment. one embodiment of a method of beverage preparation will now be described. The user may order a desired beverage to be prepared by embodiments of the machine 10 disclosed herein. The user may operate the control panel or touch screen 14 to select a size of beverage to be prepared and the type or types of flavored products to be added to the beverage.
When dispensing an iced beverage, a container 28 is deposited into one of the two container drop positions 30, 32 in step 322. The container 28 is deposited on the container holders 132 from the container dispenser 16 and moved by the container movement and positioning assembly 18 to the container holder associated with the cubed ice drop position 34 in which a predetermined amount of cubed ice is deposited into the container in step 323. The weigh scale of the container holder 132 is provided to facilitate the addition of a proper amount of cubed ice to the container in step 324. Alternatively, the robotic arm 84 could weigh the amount of cubed ice added.
The robotic arm 84 of the container movement and positioning assembly 18 is next rotated to a position in which the container 28 is placed on container holder 132 at one of two positions 36, 38 associated with the cubed and shaved ice dispensing assembly 20, where a predetermined amount of cubed ice is deposited into the container (step 323). The weigh scale of the container holder 132 is provided as part of controlling the amount of cubed ice deposited into the container.
Next, the robotic arm 84 moves the container 28 to one of the two positions 36, 38 associated with the ingredient dispenser 22 in step 325. At the ingredient dispenser 22, a predetermined quantity of a flavored product is dispensed into the container 28. The container is weighed by the weigh scale of the container holder 132 to help control the amount of flavored product or products being added to the container in step 326.
Once a desired quantity of flavored product or products is dispensed into the container 28, the robotic arm 84 moves the beverage container to a container holder 132 at one of three positions 44, 46, 48 associated with the container delivery assembly 26 where the user accesses the prepared beverage in step 327. After the beverage is removed, a rinse and clean operation may be initiated, either automatically or under the control of the user via the control panel or touch screen 14.
Once a desired quantity of flavored product or products is added to the container 28, the robotic arm 84 moves the beverage container to a container holder 132 at one of two positions 40, 42 associated with the shaved ice dispensing and blending assembly 24 in step 335, where shaved ice is added. The amount of shaved ice that is added could be weighed by the container holders 132 or the robotic arm 84 of the container movement and positioning assembly 18 (step 336). Next, the contents are mixed in the container 28 by the blades 118 of the blender drive assembly 116 in step 337.
Once the beverage is prepared, in step 338, the robotic arm 84 of the container movement and positioning assembly 18 moves the container 28 to a container holder 132 at one of three positions 44, 46, 48 associated with the container delivery assembly 26 where the user accesses the prepared blended frozen beverage.
In some embodiments, one or more sensors are provided to detect a rotational position of the robotic arm during operation of the machine 10. The sensors may embody an infrared detection system or any other suitable type of sensor.
In some embodiments, an electronics enclosure may be provided to house the electrical components of the machine 10, such as the controller.
