Definitions
- the present invention is related to an apparatus for automatically dispensing different quantities of different liquids into a single container and may be used, for example, in the preparation of mixed alcoholic beverages.
- U.S. Patent Application Publication No. 2002/0060228 A1 describing an invention by Nicol and published on May 23, 2002, discloses a Programmable Beverage Dispensing Apparatus, comprising a solenoid valves that open to allow pressurized air to flow to the respective air pump, which uses air pressure as the motive force to propel a liquid into a container, with the amount of liquid being proportional to the length of time the solenoid is open.
- U.S. Pat. No. 6,600,969 B2 issued to Sudolcan et al. on Jul.
- U.S. Pat. No. 6,422,422 B1 issued to Forbes on Jul. 23, 2002, discloses an Automatic Bar comprising a pumping device which uses a suction pump to draw liquids from a container.
- Each of these systems delivers quantity of liquid by operating for a specific time, but the rate of flow in each case depends on the volume of liquid in the container, so the actual quantity delivered changes as the amount of remaining liquid in a container changes. Better accuracy in the amount of liquid delivered is desirable for better inventory control and for ensuring that customers consistently receive the full measure of the product they are paying for.
- U.S. Pat. No. 5,255,819 B1 issued to Peckels on Oct. 26, 1993, discloses a Method and Apparatus for Manual Dispensing from Discrete Vessels with Electronic System Control and Dispensing Data Generation on Each Vessel, Data Transmission by Radio or Interrogator and Remote Data Recording, a comprising a separate radio controlled valve on each separate bottle of liquor, which communicates with a central computer to allow liquor to be poured from each bottle in a predetermined amount as sent to it by the computer and which reports the consumption to the computer via radio waves.
- This reference is more related to inventory control than dispensing mixed drinks per se.
- U.S. Pat. No. 3,991,911 B1 issued to Shannon et al. on Nov. 16, 1996, discloses an Automatic Drink Dispensing Apparatus Having Programming Means, comprising a number of pressurized liquor containers connected by tubes leading to a connector unit for delivery to a pouring head, with the mix of liquors being controlled by the solenoid valves.
- a compressed air reservoir delivers air under pressure to the alcohol reservoir 40 , thereby using pressurized air as a means of moving liquor through the lines to the solenoid valves.
- This reference will also deliver different quantities of liquor when the amount of liquid in a container changes.
- solenoid valves provide a sure start and stop to the flow of liquid through a tube, with very brief opening and closing times. But any system that relies on keeping a solenoid valve open for a predetermined length of time will deliver a different quantity of liquid under different operating conditions, such as the inevitably different amounts of liquid in the liquor containers, the air pressure, whether compressed or atmospheric and so forth.
- Use of virtually any type of pump alone results in dripping because even when the pump is not operating, liquid can move through it. Dripping is undesirable because it leads to unsightly messes, which must be continually cleaned, and to inventory shrinkage, which often represents a significant loss and in the case of caustic materials, may present a danger. Further many types of pumps are primarily designed to move fluids and do not deliver accurately reproducible amounts during same running times.
- an apparatus for automatically dispensing single or mixed drinks or the like that accurately and repeatedly measures different amounts of different liquids into a single container; that can be programmed to mix liquids according to a large number of specific recipes; that provides a drip-free final delivery system; that can be readily adapted to mix new and different recipes; that is compact and self-contained; and that is economical to own and operate.
- a gear driven measuring pump utilizes meshed gears that permit a very precisely measured amount of liquid to pass between them per revolution or partial revolution of the axle shaft of the pump. Since the pump operates at a known highly consistent rate or revolutions per minute, the volume dispensed is directly proportional to the time the pump is running, which is precisely controlled by the programmable logic controller.
- a solenoid valve which is opened to allow liquid to flow through it and closed when the pump has completed pumping the desired amount of liquid. The solenoid valve is opened when the gear driven measuring pump is turned on and is closed when it is turned off.
- the basic flow of liquid is a gravity fed, with the rate of flow and the amount of the flow being determined by the time an individual gear driven measuring pump is pumping.
- any desired number of these separate systems can be joined together and are controlled by the programmable logic controller, which is readily programmed to allow quick user selection of a number of different mixtures of different liquids, for example, different liquors, from a user friendly touch screen menu on the front of the machine.
- the programmable processing controller also tracks a number of matters of interest, such as the day and time, the numbers of specific drinks prepared by the machine, and the days on which they were prepared, and a number of managerial functions, such as a drink container or tank cleaning cycle, programming in new drink recipes and the like.
- the programmable logic controller can be operatively connected to a remote access terminal or computer to allow a review of the drink history, the additional of new drink recipes, revenue generated, the need to clean the drink containers, the need to replenish the supply of liquors in the drink containers and so forth via the Internet, wireless networking or the like, either by the user or by a centralized office, such as a turnkey vending company that installs and services the machines.

- the cabinet 12 includes a front wall 20 , a left-hand side wall 22 , a rear wall 24 , which is removable to provide access to the mechanism inside the cabinet, and a right-hand side wall 26 , which define a trapezoidal horizontal cross sections.
- a transparent window 28 is fitted and fixed into the cabinet 12 in an upper portion of the front wall 20 and portions of the left-hand side 22 and the right-hand side wall 26 provide a view of the transparent drink containers 30 , 32 , 34 , 36 , 38 .
- Each drink container 30 - 38 is cylindrical and is closed with a circular vented lid 40 having a depending lip portion 42 seated about the top edge of the cylindrical side wall 41 of each drink container 30 - 38 . Vented lids 40 prevent the drink containers 30 - 38 from collapsing as liquid is removed from them.
- a computer controlled touch screen visual display unit (touch screen) 44 which also serves as an operator or user interface, is mounted on the front wall 20 of the cabinet 12 below the transparent window 28 .
- the touch screen 44 includes a computer port 49 , such as an RS232 port or other suitable access port. All materials used in construction of the drink dispensing machine that contact the drinks and the external cabinet 12 are governmentally approved for use with food material, for example, the cabinet 12 is stainless steel.
- the drink containers, or liquid containers, 30 - 38 are arranged in a back row 45 of the three drink containers 30 , 32 , 34 from left to right and a front row 47 of the two drink containers 36 , 38 , from left to right as shown.
- a different drink liquid or liquor can be stored in each drink container 30 - 38 , with all five drink containers 30 - 38 forming a trapezoidal pattern.
- Each drink container 30 - 38 is made from transparent food grade polyvinylchloride with a capacity of two liters each.
- the automatic drink dispensing machine 10 can be utilized with any liquids.
- a stop member 46 includes a downwardly depending stem 48 fixed to the bottom wall 14 and a pair of horizontally mounted arms 50 , 52 connected to its lower end, with the horizontally mounted left-hand arm 50 and the horizontally mounted and aligned right-hand arm 52 each curved and presenting a concave curve to toward the front of the automatic drink dispensing machine 10 .
- the stop member 46 is used only to locate a drinking glass under the tubes that dispense the drink and does not pivot or toggle to actuate the automatic drink dispensing machine 10 .
- each drink container 30 - 38 includes a bulkhead fixture 54 , that is inserted through an aperture 57 in the bottom wall 128 of each liquid container 30 - 38 , that includes a female quick disconnect fitting, that is inserted into an aperture in the bottom wall 128 of each drink container 30 - 38 , and further includes depending stem member 56 , that is, the mating male quick disconnect member 56 .
- the depending stem member 56 which is a male quick disconnect fitting, is received into a receiving aperture 58 in the female quick disconnect fitting 59 at its upper end and into a liquid intake fitting on a 24 volt electrically actuated gear driven measuring pump 60 at its lower end.
- the gear driven measuring pump 60 pumps liquor downward through the tube 62 , which are operatively connected to the intake fitting 64 of a three way normally closed solenoid valve 66 , which, when opened allows the liquor to fall through the liquor delivery tubes 68 and into a drinking glass located against the stop member 46 .
- a gear driven measuring pump 60 to dispense the volume of liquor provides very accurate and repeatable volume delivery, regardless of the volume, weight or viscosity of liquid in any container 30 - 38 , atmospheric air pressure, the amount of air in any drink or liquid container 30 - 38 or the volume or weight of any amount of liquid in any drink container 30 - 38 . It has further been found, however, that a gear driven measuring pump 60 does not precisely and completely shut off the flow of liquid through it, so using it alone along the liquor delivery path leads to small drips, which are unattractive, a disadvantage this is eliminated by placing the very sure open or closed solenoid valve 66 immediately downstream of the gear driven measuring pump 60 .
- the solenoid valves 66 are electronically opened whenever a particular gear driven measuring pump 60 is pumping and is otherwise closed. Once the liquor has passed through the gear driven measuring pump 60 , all further flow of the liquor due to the force of gravity, accounting for the upper to lower arrangement of all further components, required to conveniently induce the downhill flow of the liquor into the drink glass, as described below.

Abstract
Five cylindrical containers each having an aperture in its bottom wall, are housed in a cabinet. Each container is desirably filled with a different liquid. A tube passes though the bottom wall and into a gear driven electrically operated measuring pump for each container. The pump accurately meters out a desired volume of liquid in direct proportion to the time the pump is pumping. Located downward from each pump is a connected solenoid valve, which turns the liquid flow on and off rapidly and completely. A programmable logic controller (PLC) is operatively connected to the pumps and valves and can be programmed to dispense very precise different mixtures of different liquids. A touch screen visual display unit is operatively connected to the PLC to provide substantial data on a number of different screen displays.

- The present invention is related to an apparatus for automatically dispensing different quantities of different liquids into a single container and may be used, for example, in the preparation of mixed alcoholic beverages.
- Mixing different quantities of different liquids is required in many fields, such as the manufacture of antifreeze, windshield cleaner, pesticides, herbicides, medicines, and the like. It is also desirable in the field of alcoholic beverage preparation due to the desire for many mixtures of various liquors to form specific mixed drinks, many of which have widely accepted names, allowing standardization of them. Although the present invention is described below in connection principally with the mixed alcoholic beverage business, it can obviously be utilized in any field that requires precise mixing of various quantities of different liquids.
- In the drinking establishments it is customary to employ a bartender to mix various drinks. The ability to remember a large number of different drinks and to mix them quickly and accurately are essential and difficult bar tending skills. In some cases, it may not be possible to retain enough skilled bartenders to serve all the customers promptly. In other cases, perhaps peak demand cannot be well met with the available personnel. In certain social functions such as wedding receptions, club meetings and the like, it may be desirable to serve mixed drinks but may not be economically feasible to hire enough bar tenders to meet the demand promptly. Further, unfortunately, in some cases a significant inventory shrinkage occurs due to improperly measured drink portions. Even small discrepancies between the amounts of various liquors called for in a drink recipe and the amount actually served can have a significant impact on profits.
- Therefore, it would be desirable to have a machine that can reliably dispense the various liquors in precisely metered quantities, both to relieve pressure on bar tenders and to provide a more accurately calibrated mixed drink.
- Efforts to provide such a machine have led to a number of patents.
- For example, to control the amount of liquid dispensed, some inventors have relied upon opening a solenoid controlled valve for some time period and then closing it. U.S. Patent Application Publication No. 2002/0060228 A1, describing an invention by Nicol and published on May 23, 2002, discloses a Programmable Beverage Dispensing Apparatus, comprising a solenoid valves that open to allow pressurized air to flow to the respective air pump, which uses air pressure as the motive force to propel a liquid into a container, with the amount of liquid being proportional to the length of time the solenoid is open. U.S. Pat. No. 6,600,969 B2, issued to Sudolcan et al. on Jul. 29, 2003, discloses a Beverage Dispenser Including an Improved Electronic Control System comprising valves of any suitable design to allow syrup and carbonated water to flow and a solenoid operated valve interface. U.S. Pat. No. 6,422,422 B1, issued to Forbes on Jul. 23, 2002, discloses an Automatic Bar comprising a pumping device which uses a suction pump to draw liquids from a container. Each of these systems delivers quantity of liquid by operating for a specific time, but the rate of flow in each case depends on the volume of liquid in the container, so the actual quantity delivered changes as the amount of remaining liquid in a container changes. Better accuracy in the amount of liquid delivered is desirable for better inventory control and for ensuring that customers consistently receive the full measure of the product they are paying for.
- Some approaches to the problem addressed by the present invention may be too complex to be practical. For example, U.S. Pat. No. 5,255,819 B1, issued to Peckels on Oct. 26, 1993, discloses a Method and Apparatus for Manual Dispensing from Discrete Vessels with Electronic System Control and Dispensing Data Generation on Each Vessel, Data Transmission by Radio or Interrogator and Remote Data Recording, a comprising a separate radio controlled valve on each separate bottle of liquor, which communicates with a central computer to allow liquor to be poured from each bottle in a predetermined amount as sent to it by the computer and which reports the consumption to the computer via radio waves. This reference is more related to inventory control than dispensing mixed drinks per se.
- U.S. Pat. No. 3,991,911 B1, issued to Shannon et al. on Nov. 16, 1996, discloses an Automatic Drink Dispensing Apparatus Having Programming Means, comprising a number of pressurized liquor containers connected by tubes leading to a connector unit for delivery to a pouring head, with the mix of liquors being controlled by the solenoid valves. A compressed air reservoir delivers air under pressure to the
alcohol reservoir 40, thereby using pressurized air as a means of moving liquor through the lines to the solenoid valves. This reference will also deliver different quantities of liquor when the amount of liquid in a container changes. - Use of solenoid valves provides a sure start and stop to the flow of liquid through a tube, with very brief opening and closing times. But any system that relies on keeping a solenoid valve open for a predetermined length of time will deliver a different quantity of liquid under different operating conditions, such as the inevitably different amounts of liquid in the liquor containers, the air pressure, whether compressed or atmospheric and so forth. Use of virtually any type of pump alone results in dripping because even when the pump is not operating, liquid can move through it. Dripping is undesirable because it leads to unsightly messes, which must be continually cleaned, and to inventory shrinkage, which often represents a significant loss and in the case of caustic materials, may present a danger. Further many types of pumps are primarily designed to move fluids and do not deliver accurately reproducible amounts during same running times.
- Therefore, there is a need for an apparatus for automatically dispensing single or mixed drinks or the like that accurately and repeatedly measures different amounts of different liquids into a single container; that can be programmed to mix liquids according to a large number of specific recipes; that provides a drip-free final delivery system; that can be readily adapted to mix new and different recipes; that is compact and self-contained; and that is economical to own and operate.
- Accordingly, it is a primary object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that accurately and repeatedly measures different amounts of different liquids into a single container.
- It is another object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that can be programmed to mix liquids according to a large number of specific recipes.
- It is another object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that provides a drip-free final delivery point.
- It is another object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that can be readily adapted to mix new and different recipes.
- It is another object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that is compact and self-contained.
- It is another object of the present invention to provide an apparatus for automatically dispensing single or mixed drinks or the like that is economical to own and operate.
- These objects are achieved by providing a number of individual drink containers, each having an outlet aperture in its bottom wall, which is connected to a gear driven measuring pump to accurately and repeatedly measure the amount of liquid being dispensed. A gear driven measuring pump utilizes meshed gears that permit a very precisely measured amount of liquid to pass between them per revolution or partial revolution of the axle shaft of the pump. Since the pump operates at a known highly consistent rate or revolutions per minute, the volume dispensed is directly proportional to the time the pump is running, which is precisely controlled by the programmable logic controller. Physically below the gear driven measuring pump is a solenoid valve, which is opened to allow liquid to flow through it and closed when the pump has completed pumping the desired amount of liquid. The solenoid valve is opened when the gear driven measuring pump is turned on and is closed when it is turned off. The basic flow of liquid is a gravity fed, with the rate of flow and the amount of the flow being determined by the time an individual gear driven measuring pump is pumping.
- Any desired number of these separate systems can be joined together and are controlled by the programmable logic controller, which is readily programmed to allow quick user selection of a number of different mixtures of different liquids, for example, different liquors, from a user friendly touch screen menu on the front of the machine.
- The programmable processing controller also tracks a number of matters of interest, such as the day and time, the numbers of specific drinks prepared by the machine, and the days on which they were prepared, and a number of managerial functions, such as a drink container or tank cleaning cycle, programming in new drink recipes and the like. The programmable logic controller can be operatively connected to a remote access terminal or computer to allow a review of the drink history, the additional of new drink recipes, revenue generated, the need to clean the drink containers, the need to replenish the supply of liquors in the drink containers and so forth via the Internet, wireless networking or the like, either by the user or by a centralized office, such as a turnkey vending company that installs and services the machines.
- Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, the preferred embodiment of the present invention and the best mode currently known to the inventor for carrying out his invention.
