This invention relates generally to the field of vending machines and more specifically to vending machines implementing means for a customer to select a product from a variety of frozen confectionery cups and to customize the selected cup from a selection of a variety of hard and liquid toppings.
Automated machines for dispensing frozen confectionery and other frozen confectioneries are known in the art. For example, Chirnomas (U.S. Pat. No. 5,027,698) discloses a frozen ice-cream vending machine wherein the machine dispenses pre-filled containers of ice-cream. Davis et al (United States Pat application 2004/0251270) describes an ice-cream dispensing machine for dispensing soft-serve ice-cream. Kateman et al (U.S. Pat. No. 7,052,728) describes a machine for vending single servings of different flavors, wherein selected flavorants are mixed into a base liquid prior to freezing. Jones et al (U.S. Pat. No. 7,896,038) discloses a confectionery vending machine that employs robotics to provide a customized frozen confection.
However, even though the above described devices deliver frozen confections in a somewhat custom manner, there are deficiencies in the prior technology. For example, in the Jones et al patent, an expensive robotic arm moves an ice-cream receiving cup to one of a variety of topping holding stations to have soft serve frozen confectionery delivered into the cup and then topping applied to the soft serve ice-cream. There is no ability to dispense standard frozen confectionery which tends to be harder and not suitable for dispensing through a tube. Second, there is no provision for applying the toppings in an evenly distributed manner within the cup. Third, the robotic arm is required to travel to each topping dispensing location. A simpler and more economical solution would be to have radially disposed toppings delivered to a centrally located frozen confectionery cup. Fourth, the frozen confectionery is stored in the top portion of the vending machine, requiring the entire top portion of the machine to be kept at freezing temperatures thereby incurring extra expense to maintain low temperature in an uninsulated environment, plus the likely event of excess moisture creating ice partials that can attach to the transparent front surface which defeats the intended viewing experience of the customer.
Primary aspect of the present invention is to enable a customer to interactively choose a frozen confectionery cup from multiple frozen confectionery flavors, the chosen frozen confectionery cup further to be customizable by the customer via a touch screen with selections from multiple hard topping choices and from multiple liquid topping choices.
Another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that uses a single rotatable carousel structure to store a plurality of stacked frozen confectionery cups in a freezer enclosure and to lift one cup at a time to a delivery and toppings dispensing enclosure.
Another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that uses a vertically oriented rotating arm to deliver liquid toppings to a frozen confectionery cup.
Another aspect of the present invention is to provide an interactive frozen confectionery vending machine that uses a centralized gear motor to power an arm and attached cup to receive toppings from radially placed topping canisters and deliver the toppings to a frozen confectionery cup.
Yet another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that dispenses eating utensils for use by customers.
Still yet another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that includes lockable hinged doors to allow authorized persons only access to allow machine maintenance and to enable authorized persons only to restock the frozen confectionery and toppings.
Another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that includes a backlit photo display which cycles on and off to notify the customer which liquid topping is selected to be dispensed.
Another object of the interactive frozen confectionery vending machine is to provide an interactive frozen confectionery vending machine that includes a rotatable customer access door that allows access to one cup of frozen confectionery only and closes after the customer removes the purchased cup to prevent customers from reaching inside the machine.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an exemplary embodiment of the present invention is disclosed.
In accordance with the exemplary embodiment of the interactive frozen confectionery vending machine, there is disclosed an interactive frozen confectionery vending machine comprising: a freezer enclosure, a delivery and toppings dispensing enclosure, a support equipment enclosure.
The support equipment enclosure further comprises cooling system components comprising a compressor, a condenser, coolant tubing and other standard and usual cooling system hardware. The support equipment enclosure further comprises a plurality of liquid topping canisters, an eating utensils storage and dispenser, customer selection hardware and a programmable control system.
The customer selection hardware, disposed on the front panel of the support equipment enclosure, comprises a toppings selection video display panel, customer payment processing module, the eating utensils dispenser and a customer interface touch screen.
The control system comprises a programmable digital control processing unit comprised of one or more microprocessors and other electronic and electrical components configured and programmed to process customer selections, converting the customer selections into control actions sequencing the activities of the interactive frozen confectionery vending machine. The programmable digital control processing unit further comprises customer selected payment method processing, including wired and wireless communication with payment centers.
The liquid topping canisters store liquid toppings, wherein the term liquid topping comprises any viscous liquid that can be moved by a pump, wherein the liquid topping is pumped via a viscous liquid pump, such as a diaphragm pump, a gear pump or a piston pump, to exit ports located at the distal end of a liquid topping dispensing arm via a plurality of flexible tubes.
The freezer enclosure comprises a plurality of frozen confectionery cups stored in a plurality of stacks on a rotating platform, wherein a mechanism controlled by the programmable digital control processing unit causes a customer selected frozen confectionery cup to be delivered to a frozen confectionery slidable cup retaining platform in the delivery and toppings dispensing enclosure, wherein the customer can remove the frozen confectionery cup, remove the lid of the frozen confectionery cup, then return the cup to the top surface of the frozen confectionery slidable cup retaining platform, wherein the rotatable customer access door closes, thereby initiating a sequence of dispensing the customer selected toppings.
The dispensing sequence depends on customer chosen topping, selected liquid toppings preferably dispensed first by a liquid topping delivery arm, followed by a rotatable arm's toppings dispensing motor causing a hard topping to be dispensed into the rotatable cup, the arm rotating so that the rotating cup is above the frozen confectionery cup, the rotating cup rotating one hundred and eighty degrees to drop the selected hard topping into the frozen confectionery cup, whereupon the customer removes the frozen confectionery from the frozen confectionery slidable cup retaining platform, causing the front rotatable customer access door to close.
The drawings constitute a part of this specification and include an exemplary embodiment of the interactive frozen confectionery vending machine, which may be embodied in various forms. It is to be understood that in some instances various aspects of the interactive frozen confectionery vending machine may be shown exaggerated or enlarged to facilitate an understanding of the interactive frozen confectionery vending machine.
Detailed descriptions of the exemplary embodiment of the principles of the invention are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art. It is also to be understood that the presented terminology is for the purpose of description and should not be regarded as limiting.
Referring now to

Front door 24 of the delivery and toppings dispensing enclosure can open via hinges 41. Front panel 56 of support equipment enclosure can be opened via hinges 58. Rotatable customer access door 16 of the delivery and toppings dispensing enclosure 4 is opened and closed by the programmable digital control system to allow a customer access to a purchased frozen confectionery cup as shown in the section view in
Furthermore,
The customer use experience is as follows: The customer presses a central graphic button on the touch screen 14. The customer is prompted by a visual prompt, a voice prompt or a combination of the visual and voice prompts, to choose from a plurality of frozen confectionery flavors. The customer is then prompted to choose none or one or more hard toppings by pressing on graphic buttons that are associated with each topping. Then the customer is prompted to choose from a plurality of liquid toppings by touching graphic buttons that are associated with each liquid topping. Then the customer is asked to pay for the frozen confectionery and toppings via the payment processing module 60 located at the front of enclosure 2. After successful completion of the payment process, the slidable cup retaining platform 44 opens and the selected frozen confectionery cup rises from the freezer enclosure 6. The rotatable customer access door then opens allowing the customer to remove the cup of frozen confectionery and remove the lid of the frozen confectionery cup and then replace the cup inside the delivery and toppings dispensing, a cup presence sensor will determine whether the frozen confectionery cup has been removed and replaced. The rotatable customer access door closes after the frozen confectionery cup has been replaced. Then the selected liquid toppings are dispensed, and then the selected hard toppings are dispensed. Finally, the rotatable customer access door opens again and allows the customer to remove the finished frozen confectionery treat. Upon removal, the slidable cup retaining platform closes and the rotatable customer access door also revolves to the closed position to wait for the next customer. It will be apparent to those skilled in the art that the cup presence sensor can be implemented by one or more of available means, such as a weight sensor, a photo sensor, or another proximity sensor.
The process of selecting frozen confectionery and toppings may also be facilitated wirelessly, such as by a phone app. Additionally, the amount of frozen confectionery and toppings stored within the interactive frozen confectionery vending machine at any time may be sensed by standard sensing devices located throughout the machine and wirelessly transmitted to a service person at a remote location.
If there is a malfunction of any of the electro mechanical features or of the compressor and condenser used to keep the freezer enclosure cold, the entire interactive frozen confectionery vending machine 100 will become inactive, and any attempt by a customer to operate the interactive frozen confectionery vending machine 100 will be unsuccessful until entire interactive frozen confectionery vending machine 100 is brought back to proper working order. The functional status of the interactive frozen confectionery vending machine may be wirelessly transmitted to a service person at a remote location.
In another embodiment, not shown, the shape of the frozen confectionery cup 26 may be rectangular or another geometrically irregular shape. Yet in another embodiment, not shown, the interactive frozen confectionery vending machine can be easily adapted to products other than the frozen confectionery presented in the exemplary embodiment of the invention, such as frozen savory meals and snacks.
