Description
[0001] The present application claims priority from U.S.
provisional patent application Ser. No. 60/956,942, filed on Aug.
21, 2007.
FIELD OF THE INVENTION
[0002] The present invention relates to automatically fulfilling
beverage orders.
BACKGROUND TO THE INVENTION
[0003] Beverage orders, including orders for alcoholic drinks, are
traditionally fulfilled manually by bar or waiting staff. However,
there are some situations where this is a limitation on the number
of drinks that can be served, e.g. at large events, such as
concerts or race meets, where there may be hundreds or thousands of
potential customers.
[0004] An alternative known method of purchasing a drink is via a
vending machine. However, to date such machines are not widely used
for dispensing alcoholic drinks and are also limited to dispensing
cans of beverages and/or one drink at a time rather than orders
comprising more than one drink selected from a range. Thus,
currently available vending machines are not suitable for
fulfilling a large number of beverage orders, particularly
alcoholic drinks, quickly.
[0005] Embodiments of the present invention are intended to address
at least some of the shortcomings of existing techniques.
SUMMARY OF THE INVENTION
[0006] According to one aspect of the present invention there is
provided apparatus adapted to automatically fulfil a beverage order
including:

DETAILED DESCRIPTION OF THE DRAWINGS
[0059] Referring to FIG. 1, an example of the beverage order
fulfillment system is shown. The system illustrated includes a
beverage dispensing terminal 100 and a point of sale terminal 101.
It will be appreciated that this arrangement is exemplary only and
the number and locations of the terminals can vary according to
particular requirements. The point of sale terminal 101 is intended
to allow customers to order drinks and pay for them. The terminal
101 issues a ticket which the customer then takes to the dispensing
terminal 100 where the ordered beverage(s) is/are dispensed
automatically. Fencing 103 or the like may be provided to channel
customers to/from either or both of the terminals and assist with
orderly queuing.
[0060] In the illustrated embodiment, when a customer places an
order at the point of sale terminal 101 data representing the order
is communicated to the dispensing terminal 100. This communication
can be achieved by any suitable means, e.g. using wireless or
wire-based communications hardware. Details of the order placed are
then stored within a database in an electronic storage device, e.g.
a hard drive, that is in communication with a processor also
located within the dispensing terminal 100. When an order ticket is
presented to the dispensing terminal details of its order can be
cross referenced with the order data held in the database so that
the correct beverage(s) is/are automatically dispensed. In another
embodiment, data relating to the order may be stored in a storage
device within the point of sale terminal 101 and/or in another
separate device.
[0061] In some embodiments, the order database may be accessible to
other software/computers, e.g. by complying with Open Database
Connectivity standards. The database may also store information
that is not directly required for fulfilling a beverage order, but
which may be used for other purposes, e.g. obtaining statistics
regarding sales of various products, which can be useful for
marketing or re-stocking purposes. In some cases the database may
store information including a reference number unique to the order;
the beverage(s) specified in the order; the cost of the order; the
payment method and time/date that the order was made. Additionally,
the database may store data relating to the fulfillment of an
order, e.g. the time the order was fulfilled at the dispensing
terminal 100. Thus, the database may be used to gather/collate
information including the following: total sales; quantity of sales
of each type of beverage; card types used for payment; throughput;
average dispensing time (e.g. starting from order placement to
removal of filled cups from dispensing terminal); total takings
over a given period; profit over a given period; number of users;
most popular choice(s) of beverage. If the customer is using a "top
up"/reward card for payment then details of his previous order(s)
may be stored and retrieved to enable him to place a repeat order
quickly.
[0062] It will be appreciated that the point of sale terminal 101
can take various forms. In one example the terminal 101 includes a
cabinet housing a computer with a touch screen that presents a menu
of beverages and is capable of receiving payment in the form of
cash or a credit/bank card. Alternatively, if the system is only
configured to dispense one type of beverage then only the number of
drinks required may need to be specified in the order by the
customer, with the type of beverage being implicit in such an
order. The touch screen can display the cost of the order as it is
made by the customer and may allow the customer to cancel/modify
the order at any time before payment is made. A limit on the number
of (different) beverages that can be specified in a single order
may be put in place. The terminal can also include a numeric keypad
to allow entry of a PIN number when a card is being used to make
the payment. It will be apparent to the skilled person that many
variations are possible, e.g. the user interface could take a
different form, such as electro-mechanical buttons or speech
recognition, and different types of payment could be processed,
e.g. a "top-up" card with a magnetic strip or chip. In alternative
embodiments, the payment terminal may be integrated within the
dispensing terminal and so a step of producing a ticket and then
presenting it to the dispensing terminal may be omitted; however,
it has been found that having the point of sale and dispensing
terminals located remotely from each other can be beneficial in
terms of throughput and also offers more flexibility to customers.
It will also be understood that alternative payment schemes could
be implemented, e.g. a customer could pre-pay for drinks remotely,
e.g. via a website or telephone line, and print out/be posted a
ticket, or a customer could pre-order/pay-pay for drink at the time
of buying an event ticket, with a separate ticket being used at
that time (or the drink payment/order may be encoded on the event
ticket).
[0063] FIG. 2 is a perspective view of an example of the dispensing
terminal 100. The terminal 100 includes an outer shell 102 which
houses components for processing and fulfilling beverage orders. In
the illustrated example the terminal includes four service points
104A-104D, each of which includes/is located adjacent a respective
ticket reader 105A-105D. A video screen 106A-106D is located above
each service point and may display order-related information or
other material such as advertisements.
[0064] In use, a customer stands next to one of the service points
104 and presents the order ticket produced by the point of sale
terminal 101 and then waits for the ordered beverage(s) to be
dispensed. Each of the service points is associated with a separate
dispensing module inside the shell 102, which will be described in
detail below. Thus, the example dispensing apparatus is capable of
fulfilling up to four beverage orders at a time. However, it will
be understood that this number is exemplary only and alternative
versions of the terminal 100 can be built to fulfil different
numbers of orders simultaneously.
[0065] The terminal 100 further includes a first control cabinet
108 containing cooling apparatus (shown schematically at 108A) for
keeping beverages within the terminal 100 at a low temperature,
e.g. about 1-2.degree. C. The terminal 100 also includes a second
control cabinet 109 that contains computer equipment (shown
schematically at 109A), which can include a PC and circuit boards,
for controlling the dispensing system, processing orders and
maintaining the order database, etc. The locations of the cabinets
in the Figure is exemplary only and either or both could be
integrated within the main body of the shell 102 or be at least
partially separate from the main body.
[0066] FIG. 3 is an exploded diagram (rear perspective aspect)
showing an example of how the shell 102 of the dispensing terminal
100 can be constructed. The example shown in FIG. 3 shows a
slightly different construction to the example of FIG. 2, and it
will be understood that the appearance and construction of the
dispensing terminal 100 can vary and it need not have the same
shape, dimensions or configuration shown. The example shell of FIG.
3 comprises a set of floor panels 110 (e.g. 2.0 mm Aluminium 5 bar
sheets over 9 mm plywood) that, when assembled, are held between
floor beams 112. Internal skirting boards 113 may also be provided.
In use, the floor panels can be mounted upon chevrons 111 for
stability, as the terminal may be placed in use on an uneven lawn,
etc.
[0067] The side walls of the shell can be formed by a series of
vertical panels 116 held together between vertical beams 114.
Various construction techniques can be used to secure the various
panels together, e.g. they may include a tongue/groove formation.
The entire terminal may be constructed so that it can be easily
assembled/dissembled to make the system conveniently relocatable so
that it can be hired to/placed at different venues. The upper
surface of the terminal can be formed of a series of ceiling panels
120 fixed between elongate ceiling beams 122 and PVC external
corner pieces 124. Components 126 for suspending the ceiling from
an overhead construction may also be provided. A lockable,
insulated hinged door 118 (or other suitable sealable apparatus)
may be provided to allow access to the inside of the shell for
maintenance purposes.
[0068] As mentioned above, the external appearance and dimensions
of the shell may be selected on an individual basis, but the
external dimensions of the example shown in the Figures are: height
2,400 mm, width 3,460 mm and depth 2,160 mm, and the internal
dimensions are 2,240.times.3,000.times.2,000 mm (all approximate).
The dimensions of the apertures forming each of the service points
104 may be around 300.times.500 mm, with the apertures being spaced
apart by about 300 mm and the door 118 may have dimensions of
around 0.7 m.times.1.92 m.
[0069] The shell 102 in the example is intended to contain cooling
apparatus and so is insulated and effectively acts as a cool room.
At least some of the shell panels may be formed of pieces of rigid
material, e.g. a metal, such as aluminium or steel, that form a
sandwich with an insulating material filling, such as polyurethane
injected. The resulting thickness of such panels may be between
around 70 to 80 mm. The panels may have coatings, e.g. an external
finishing such as the "Colour Coat HPS 200" range produced by
Corus. The internal surfaces of the panels may have a food safe
finish.

is "MAS221N18S Uniblock Weather" produced by Zanotti Spa of Italy.
An associated control system will also be used to configure
settings such as the temperature, defrost management, time and
temperature termination, fan control and alarm function. The
cooling apparatus may be mounted through the wall or ceiling of the
shell and can include a compressor crank case heater, high pressure
switch for condenser fan control, and twin solenoid valves for hot
gas defrost and automatic condensate water evaporation. The power
source for the cooling apparatus and/or other electrical components
of the system may be external or the system may contain its own
power source, e.g. batteries, for at least some of the
components.
[0071] FIG. 4 includes a partial view of the shell 102 that
illustrates how an inner frame 130 and other components contained
inside it. The inner frame 130 and some of the components are also
shown in FIG. 5. The inner frame 130 can be formed of any suitable
rigid material, e.g. 80.times.40 steel box, connected together
using appropriate means, e.g. nuts/bolts, screws, adhesives or
welding. The frame comprises a lower framework 132 and a plurality
of upper frameworks. Each of the upper frameworks contain
components that can be considered to be dispensing modules
associated with each of the service points 104A-104D, each module
being capable of independently fulfilling different orders. For
clarity, only one of the upper frameworks 134A and dispensing
modules (located at the left hand end of the frame in FIG. 5) is
shown.
[0072] The lower framework 132 contains a plurality of storage
containers, e.g. kegs 502, that are used to supply the upper
dispensing modules. The various kegs 502 may contain one or more
different types of beverages, e.g. lager, bitter, cider or stout.
Pipes and pumping apparatus (not shown) connect some of the kegs to
dispensing nozzles that are part of the dispensing modules. These
components comprise ancillary dispensing equipment that can be
controlled by the system control computer and typically include
pressure regulators, pneumatic controllers/actuators, pumping
components, (automated) line cleaning components and in-line
cooling components (e.g. glycol based).
[0073] The system may incorporate an automatic keg changeover
arrangement (not illustrated) that enables more than one keg
(normally of the same product type) to be connected to a single
dispensing nozzle. When a detector (e.g. liquid level detector)
determines that a first keg is/approaching empty (e.g. only enough
fluid left in the keg to fulfil a certain number, e.g. one, of
further order(s)), the arrangement automatically changes to another
keg without user intervention, thereby ensuring continuous supply
of product. This can be achieved, for example, by pinch valves
mechanically closed with springs and opened by linear actuator, or
a manifold system, in communication with the detectors fitted to
the kegs. Components of the dispensing module within the upper
framework 134A can be seen in more detail in FIG. 6. The dispensing
module includes an access door 602 that, in use, opens/closes the
aperture in the shell 102 at the left-hand end service point 104A.
The door 602 can be slid open/closed in a vertical or horizontal
direction by virtue of being connected to a lifting device 604
(e.g. a roundline cylinder, cog, belt or pulley system or similar),
which is controlled by code executing on the computer 109A. The
access door 602 forms a front cover for a cuboid-shaped thermal
cut-off chamber 606 located within the framework 134A. The base of
the chamber is formed by an elongate platform 607. In use, a
customer retrieves dispensed beverage(s) from this chamber.
[0074] Part of the rear vertical wall of the chamber 606 is formed
by a vertical panel 608 that is mounted on a moveable tray 610. The
tray 610 is mounted on a set of rails 614 and can be moved
horizontally by means of actuators (under the control of the
computer 109A) away from/towards the thermal chamber 606 relative
to the opposite wall of the dispensing terminal. This direction
will herein be referred to as the X axis. It will be appreciated
that instead of a solid tray 610, a frame-type elongate member
could be provided, formed out of one or more pieces.
[0075] The rails 614 can also be moved vertically (this direction
will herein be referred to as the Y axis) by virtue on being
mounted on a set of lifting cylinders, with one cylinder located
at/adjacent each end of the rails. Cylinder 616A is visible on the
rear end of the left-hand rail 614 in FIG. 6. In the example four
25 mm bore double acting compact pneumatic cylinders (such as the
NZ series produced by Hoerbiger-Origa UK of Tewkesbury,
Gloucestershire, United Kingdom) are used to move the two rails
simultaneously over a vertical distance of around 30 mm, and so are
capable of adjusting the height of the rails and all attached
components, including the tray 610.
[0076] The dispensing module further includes a set of dispensing
nozzles 620. In the example three nozzles 620A-620C depend from the
lower surface of an elongate tubular bar 622. The nozzles
(approximately 245 mm in length) are arranged spaced apart by gaps
of around 40-45 mm in a line along the bar. The bar 622 contains
pipes that are connected to the kegs in the lower framework. The
bar is attached to a member 624 that is slidably mounted on a
vertical post 625. The member 624 is moveable up/down on that post
(i.e. along the Y axis) by means of actuators (not shown). The
pipes in bar 622 run through the inside of post 625, down out of
the bottom of the framework 134A and to the kegs. The post 625 (and
attached components) is moveable horizontally/sideways between the
ends of a pair of parallel rails 626A, 626B upon which it is
mounted. The rails extend in a direction substantially
perpendicular to that of the post 625. The horizontal directions
along which the post 625 can move over the rails 626 will herein be
referred to as the Z axis.
[0077] The example dispensing module of FIG. 6 also includes three
stacks of receptacles 630A-630C that are releaseably held by
respective dispensers 632A-632C; however, it will be understood
that this is exemplary only and different numbers/configurations of
receptacle stores could be provided, e.g. a 4.times.4
grid-arrangement of stacks (as in the alternative embodiment of
FIG. 11 discussed below). The receptacles can be open containers,
such as frusto-conical cups formed of any suitable material, e.g.
plastic, starch or cardboard. As will be described below, each
dispenser can release the lowermost cup in its respective stack
into the tray 610. The tray 610 is an elongate flat body including
three apertures 611, each aperture being located and dimensioned to
receive one of the cups from the stacks when the tray is correctly
positioned. The diameter of each aperture corresponds to the
diameter of an upper (wider) region of a cup. It will be
appreciated that the components of the dispensing module can be
modified so that a different number of cups, e.g. four, can be
processed.
[0078] The dispensing module further includes three weighing
devices (the leftmost one 640 visible in the Figure) connected to
computer 109A, each weighing device being located below the
operating location of a respective one of the three nozzles
620.
[0079] In an alternative embodiment, the system can include a
(fixed or proportional) flow regulator with electronic pressure
control (fixed or proportional). The flow rate is monitored with
one or more flowmeters per nozzle. In-line pressure and product
temperature is measured in order that an electronic adjustment may
be made if needed to ensure that the correct volume of beverage is
dispensed. Each of these elements is fed into the control system
and adjustments are made to ensure product is dispensed in the
appropriate quantity and quality, e.g. Pint (0.568 litre),
half-pint (0.284 litre), Litre or half-Litre, etc.
[0080] FIG. 7 is a perspective view of one example of the
mechanisms that are used to position the tray 610 and the set of
nozzles 620. The tray rails 614 can each include a toothed belt and
internal bearing guide (not shown) that are driven by actuators
(e.g. with 2:1 belt gear reduction gearbox) connected to a drive
shaft 703 operated by a stepper or servo or DC or linear motor 704.
This arrangement (or similar) can enable the tray, when it is
fitted on mountings 702A, 702B that are connected to the belt, to
travel along the X axis. Suitable components can be obtained from
Hoerbiger-Origa UK.
[0081] Similar suitable components for the traverse (over rails
626) and vertical (over post 625) movement may also be obtained
from the same manufacturer. For example, the vertical movement of
the member 624 on post 625 can be achieved by a Hoerbiger
"OSP-E32ST" trapezoidal screw drive linear actuator with an
internal bearing guide, driven by a stepper or servo or DC linear
motor. The skilled person will understand that alternatives to the
tray and nozzle positioning device described are available, which
may include electro-mechanical or hydraulic movement means. It will
be understood that the mechanisms for moving the nozzles and the
cups described are exemplary only. In alternative embodiments,
components may be provided that allow sets of cups to be moved
independently of other sets of cups, e.g. to different nozzles.
This means that in some cases the nozzles may not need to be
moveable/repositioned during a dispensing operation. Similarly,
components may be provided for moving sets of nozzles independently
of other sets of nozzles within a single dispensing module. In some
cases this can mean that the cups do not need to be moved in a
horizontal direction during a dispense operation, e.g. they are
filled at the service point. In some embodiments, the system may be
capable (in a single dispensing module) of dispensing more than one
beverage specified in an order. In this case more than one beverage
specified in the order will be selected for substantially
simultaneous dispensing.
[0082] An example of the operation of the dispensing system will
now be given. FIG. 8 illustrates exemplary steps that a customer
can perform in conjunction with the point of sale terminal 101. The
interaction begins at step 802, e.g. the customer touches a
"welcome" screen on the terminal, and at step 804 the customer
proceeds to select the type/quantity of beverage(s) required. At
step 806 the customer is given a chance to confirm his selection
and then at step 808 the chooses the payment method. If the chosen
payment method is cash then at step 810 the terminal 101 is
configured to accept bank notes and/or coins. This can be achieved
using known apparatus such as supplied by Money Controls of
Cleaveland Ohia, USA/Oldham, UK. If the money receiving component
indicates at step 812 that the required amount has been received
then at step 814 a ticket is printed (and change may be given if
appropriate). An Epic 950 device produced by Ithaca may be used for
this operation. At this point the system's order database can be
updated with details of the order placed.
[0083] It will be understood that a printed ticket is only one
example of a means of allowing a customer to present an order that
has been paid for to the dispensing terminal 100. The order details
may be encoded on the ticket, or the ticket may simply include a
reference number/code that acts as a key for looking up the order
details in the database of the dispensing terminal. The ticket may
be formed of any suitable material, such as card or lightweight
plastic, and the details may be formed on it by means of a printed
bar code or other suitable method, e.g. punch holes. Alternatively,
customers may be provided with a card (e.g. a "top up" card) having
a magnetic strip or a smart card that can be used for the
transaction.
[0084] If the payment method selected at step 808 is a
credit/debit/bank card then at step 816 a prompt is displayed for
the customer to insert his card into an appropriate card reader,
such as one supplied by YESPay International Limited of Barnet, UK
on the terminal 101. The card is then read and checked at step 818
and if the result is positive then control is passed to step 814,
where a ticket is printed as described above. If the card is
rejected then at step 820 an appropriate message is displayed to
the customer and the order is rejected. The customer interaction at
the ordering terminal 101 terminates at step 822, following step
814 or step 820.
[0085] FIG. 9 illustrates schematically exemplary steps that can
take place during user interaction at the dispensing terminal 100.
Reference will also made to the sequence of actions shown in FIGS.
10A to 10H, which illustrate the components of one dispensing
module in the terminal 100. The interaction begins at step 902,
which typically involves the customer presenting the printed ticket
to a ticket reading device 105A-105D at one of the service points
104A-104D. The position/configuration of some of the components of
the dispensing module at this point is shown in FIG. 10A. At this
stage, the door 602 is closed and the tray 610 is located adjacent
it (at a first position 1001 in the X axis), so that the panel 608
substantially seals the chamber 606.
[0086] At step 904 the ticket reading device either reads the
beverage order details from the ticket, or uses reference
information read from the ticket to obtain details of the order
from the database. After reading an order/reference from the
ticket, the database entry for that order may be deleted or flagged
so that it can only be fulfilled once.
[0087] At step 906 a number of cups corresponding to the number of
beverages specified in the order (or the maximum number that can be
filled in one dispensing sequence if the amount of beverages
specified in the order exceeds that) is/are placed in the tray 610.
In order to achieve this, the tray 610 moves from its first
location 1001 to a second location 1002 (see FIG. 10B) beneath the
cup dispensers 632. Up to three of the dispensers release the
lowermost cup from their respective stacks, as appropriate. As
FIGS. 10A-10H are side views, only the cup 631 nearest to the
viewer can be seen.
[0088] At step 908 the dispensing of a first beverage specified in
the order is commenced. The first beverage will typically be the
first one as entered by the customer on the point of sale terminal
101, although it could be selected in some other manner, e.g.
taking into account relative positions of nozzles associated with
the various types of beverages, a prior operation of the apparatus,
or the settling time of any particular beverage.
[0089] At step 910 the cup tray and nozzles are moved to
appropriate positions for dispensation of the first beverage.
Typically, the cup in the leftmost aperture in the tray 610 will be
the first to be filled, but it will be understood that this could
be varied. The three nozzles 620A-620C will normally be configured
to deliver different types of beverage, although in some cases at
least one of the nozzles could dispense the same type of drink as
another one of the nozzles, e.g. be connected to an additional keg
of a popular drink. Thus, three points/coordinates in the X axis,
labelled 1003A, 1003B and 1003C in FIG. 10C are associated with the
dispensing positions of nozzles 620A, 620B and 620C, respectively.
The computer 109A obtains the appropriate coordinate for the nozzle
that dispenses the specified beverage and transmits a signal to the
tray positioning components, e.g. motor 704 actuator, to move the
tray to the appropriate location. In the example of FIG. 10C, the
tray 610 moves so that cup 631 is positioned beneath the middle
nozzle 620B, i.e. at location 1003B.
[0090] The positioning of the tray/cup also involves placing the
cup to rest on the weighing device 640 associated with the nozzle
that performed the dispensing operation, which is used to check
that the correct amount of beverage has been dispensed. To achieve
this, the tray frame/rail 614 is moved, under the control of the
computer, downwards along the Y-axis (see arrows 1004 in FIG. 10D)
using the cylinders 616 so that the cup is no longer supported by
the tray 610 and instead rests directly on the weighing device
640.
[0091] The processor will also arrange for the appropriate nozzle
to be positioned above the cup that is to be filled. The locations
of the three cups/apertures in the tray beneath the appropriate
nozzle are associated with three respective coordinates in the
Z-axis. The computer obtains this coordinate for the cup that is to
be filled and transmits a signal to the nozzle positioning
components to move the nozzles along rails 626 to the appropriate
location above the cup. Thus, the cup and nozzle can be positioned
very precisely for dispensation of the beverage.
[0092] At step 912 the appropriate beverage is dispensed into the
cup 631. To achieve this, the bar 620 is moved downwards along the
Y-axis (by means of relative movement of member 624 on post 625
under the control of the computer) so that nozzle 620B is at least
partially positioned within the cup 631, as shown in FIG. 10E.
Having the nozzle in this position is particularly suitable for
dispensing alcoholic beverage such as bitter, but it will be
understood that in some cases the nozzle could be positioned above
the cup and need not be located within it. The nozzle 620B is then
actuated and fills the cup for a predetermined period of time. The
period of time will be determined by various factors, including the
temperature of the liquid, the specific gravity of the beverage,
the configuration of the dispensing pump, etc. This information can
be taken into account and a look-up table or the like can be stored
by the control computer, e.g. indicating the dispense time for each
type of beverage having a certain specific gravity. Typically, this
dispense operation will vary between 1.9 and 3.6 s. The components
in the example can dispense around 38 litres of beverage per minute
(in continuous use), which typically allows one pint (0.473 litres)
of beer to be dispensed in around 1.9 seconds. It will be
appreciated that the apparatus can be modified to dispense any
required volume of liquid.
[0093] FIG. 10E does not illustrate part of the tray rail 614 to
show the cup 631 resting directly on top of the weighing device
640. In order to ensure that the correct amount of liquid is
dispensed into the cup (e.g. to comply with UK Weights and Measures
regulations), the cup is then weighed using device 640, with the
measurement being relayed to the computer. Having the beverage in
the system maintained at a constant temperature by the cooling
apparatus, plus the ability to accurately position the empty cup
for filling means that the system can accurately fill a cup with
the correct amount of beverage. However, if the weighing operation
indicates that the cup is not sufficiently full (in the UK, for
example, it is not acceptable for the weight of an alcoholic
beverage sold as 1 pint (0.473 litres) to be outside a threshold
that corresponds to around 2.8 grams when weighed) then the nozzle
actuator is again activated to fill the cup with a predetermined
amount. Further weight checks may be performed, followed by further
refilling operations if necessary. Using the weight of a dispensed
beverage/cup is not commonplace for determining whether the correct
amount of beverage has been dispensed and it has been found to be
quicker (and requires less complex/costly components) than
attempting to measure the volume of liquid dispensed in the present
system.
[0094] At step 914 the dispensation of the next beverage (if any)
specified in the order for the current dispensation cycle is
commenced. The "next" order may be simply the next one in the
series as input by the customer at the payment terminal, or other
considerations, similar to the ones discussed above, may be used to
determine it. Steps 910-914 are repeated for this order (but not
described, for brevity), with the nozzles 620/bar 622 moving first
upwards in the Y direction (see FIG. 10F) to be clear of the cups
before moving across along the Z-axis to be positioned above the
next cup that is to be filled. The tray 610 is also moved back up
so that it holds the cup(s).
[0095] When all of the beverages specified in the order (or the
maximum that can be dispensed within a single dispensing cycle)
have been dispensed (step 916) then the tray 610 is moved (at step
918) along rail 614 back to position 1001 adjacent the access door
602, as shown in FIG. 10G. At this point the panel 608 attached to
the tray 610 substantially closes the gap in the rear wall of the
thermal chamber 606 to mitigate temperature increase from outside.
It will be understood that further temperature maintenance could be
achieved by blocking the aperture in the rear wall of the chamber
606 when the panel 608 is not present, e.g. by means of a further
moveable panel that slides up/down to fill the aperture.
[0096] The access door 602 is opened at step 920, as shown in FIG.
10H, and at step 922 the tray 610 moves down so that the cups rest
on platform 607, making them easier to collect. The user is then
allowed to take the filled cup or cups. At least one sensor
(illustrated schematically at 1010) may be provided to detect
removal of the cups from the tray 610 and/or that it is clear for
the door 602 to close again.
[0097] If there are more than three beverages in the order being
processed then at step 924 the dispensing cycle, e.g. steps 908
onwards, starting with the next beverage in the order that has not
yet been dispensed, will be performed for the next three (or less)
beverages, otherwise processing of the current order ends at step
926 and the apparatus is ready to receive another order ticket. It
will be appreciated that the sequence of operations described above
is exemplary only and it is possible that the order of some of the
steps could be varied and/or some could be omitted. For instance,
the nozzles could be moved to above the appropriate position for
filling a cup before the cup is positioned there.
[0098] FIG. 11 illustrates components of an alternative version of
the dispensing apparatus. In this version, the position of the cup
stacks 630' are substantially fixed in position and the cup holder
610' moves between the front and rear faces of the terminal in
order to fulfil the beverage orders. There is also a rear door 1102
for the cuboid shaped chamber 606' at the front of the device that
acts as safety device so that the operator/customer is not
endangered by any moving parts.
[0099] FIG. 12 shows an example of an outer shell 1202 that can be
fitted around the inner components shown in FIG. 11. It will be
understood that other components, e.g. kegs, will also be included
in use.
[0100] FIG. 13 details the cup holder 610' of the second
embodiment. The holder includes one or more (six in the example)
elongate members 1302 ("guide pegs") that extend upwardly and at an
outward angle from ring-shaped components 1304 that are configured
to hold the base of the receptacles. Each (of up to four) filled
receptacle is held within this arrangement ready for collection by
the customer from the chamber 606'. The cups with dispensed product
are presented on the members/pegs. There is one peg for each filled
cup, so in this embodiment four pegs are included.
