BACKGROUND
[0002] 1. Field
[0003] The present system relates generally to automated and
modularized vending machines that can be custom deployed in diverse
configurations. More specifically, the present system relates to
automated vending systems utilizing an improved robotic dispensing
module and associated inventory modules that can be assembled and
configured to create diverse vending arrangements, with components
linked together via a virtual integrated network.
[0004] 2. Description of the Related Art
[0005] Numerous vending machines exist for selling or vending
diverse products through an automated, or `self-service` format.
Vending reached popularity in the late 1800's with coin-operated
devices dispensing diverse merchandise. More recently vending
machines have evolved to include robotic dispensing components,
and/or PCs and virtual interfaces. These new vending platforms have
emerged in the marketplace under the popular descriptions
"automated retail," "interactive retail," and/or "interactive
retail displays." Such vending machines may be deployed within a
variety of commercial or public settings. They typically include
illuminated displays that seek to offer convenient purchasing.
[0006] In the vending arts, machines historically have a similar
design and orientation that make them unable to easily change
machine sizes and configurations, inventory storage sizes and
product form factors without rebuilding or redesigning the machine.
Typically machines are "one size fits all". There are some models
of traditional vending machines that allow additional inventory
areas to be added on, but these models do not utilize a robotic
dispensing unit to move the product from the shelf to the
collection area and rely on gravity (drop) systems. Because of the
expense of robotic delivery systems and the configuration of these
systems, these machines have been constrained to serving one user
at a time through one side of the machine. In addition the machines
come in a single size format and two machines have to be stacked
adjacently to expand site capacity. In more modern robotic
machines, the size of the machines tends to be larger than
traditional vending machines and units cannot be reduced based on
the robotic architecture and production of the machine. In all of
these machines, the robotic dispensing system is built as a
continuation of the inventory system and cannot be easily
separated.
[0007] The present system introduces a preferred mechanism for
dispensing items in a vending machine or automated retail store. It
is preferably used in conjunction with an isolated and centralized
robotic dispensing system that can support multiple inventory areas
and technologies within those areas. The present system provides
the ability to collect items delivered from a variety of inventory
dispensing systems from multiple sides. It also provides the
ability to deliver these collected items to users out of multiple
sides of the machine allowing more than one person to
simultaneously conduct transactions within the same machine, or to
function with one or more inventory cabinets without any major
modifications to the mechanism.
[0008] There is great value in having a common mechanism that can
handle receiving merchandise from multiple inventory cabinets with
various types of inventory tray dispensing mechanisms.
[0009] Being able to use multiple types of inventory tray
mechanisms with a single dispensing system allows a greater range
of possible inventory that can be dispensed. Specialized inventory
trays can be customized to fit merchandise of varying form factors
and still use the common centralized robotic dispensing system with
reliability. This allows the machine to adapt and evolve over time
without having to redesign the end dispensing system saving cost
and development time.
[0010] These various inventory areas can be used with the same
dispensing system allowing a great deal of flexibility in how the
machine is configured. A machine can be composed of inventory
elements, display units and a central dispensing area "strung
together" enabling the machine footprint to grow/contract depending
on environmental constraints. Inventory solutions can be updated
and reconfigured to work with the central dispensing mechanism
without significant customization of the dispensing mechanism,
allowing for rapid accommodation of new types and amounts of
merchandise for purchase or promotion.
[0011] This central dispensing system design allows greater
reliability of dispensing by providing a uniform broader surface
area (landing pad) for products to dispense. It also reduces axes
of motion by 1 (e.g. X, Y, and Z reduces to Y and Z motion) by
eliminating excess movement through inefficient placement of
inventory and robotic components. Elimination of excess movement
reduces potential points of failure and additional calibration and
programming, in addition to increasing power efficiency and
delivery speed. This design affords the ability to dispense out of
multiple sides of the machine allowing more than one user to use
the machine at the same time.
[0012] It is thus desirable to provide a method and mechanism that
enables a wide range of inventory to be dispensed to a user with a
common end dispensing system. It is also desirable to be able to
isolate this mechanism in a standalone structure that can be
attached to one or more inventory areas.
SUMMARY
[0013] The present system consists of a conveyor, product
collection wings, elevator mechanism, and supports that make up a
robotic gantry. In the present system's preferred configuration, it
is connected to a series of physical merchandise displays,
promotional/digital signage, automated mechanical/dispensing,
and/or transactional modules that can be assembled and configured
to create an automated retail store, vending unit, or interactive
retail display of any size and link together via a virtual
integrated network. The present system allows for a highly
customizable vending machine of different sizes and configurations
that can dispense a wide array of items all utilizing a common
robotic dispensing module.
[0014] In accordance with one aspect of the present system, there
is a robotic elevator operated by one or more motors that delivers
a landing platform to meet items that are located in various
inventories. The elevator positions itself at a close height
proximity that prevents items from being damaged as they are
dispensed from their holding area onto the robotic platform.
[0015] In accordance with another aspect of the present system, the
platform consists of a conveyor that can rotate in either direction
to move the collected item to a designated user collection
area.
[0016] In accordance with another aspect of the present system, the
conveyor delivers the item into a secure designated collection area
that consists of a space to receive the dispensed items and a
method to secure the internal dispensing mechanism in order to
prevent tampering by a user, or injury to the user.
[0017] In accordance with another aspect of the present system, the
inventory areas are attached to the centralized robotic dispensing
mechanism. These inventory areas can vary in size to accommodate
different product mixes but attach to the central robotic
dispensing system in the same manner.
[0018] In accordance with another aspect of the present system, the
display areas can vary in size, configuration and appearance to fit
the products or items being merchandised.
[0019] This system and design improves the efficiency of dispensing
items by allowing one or more inventory areas of various sizes to
be attached to a centrally located and common robotic collection
and dispensing system. Because of this design, there is no need for
redundancy of expensive robotic components when increasing
inventory size. By isolating the inventory retrieval and dispensing
mechanism from the inventory storage area, a multitude of different
inventory areas can be attached without the need to redesign this
subcomponent when altering machine size or configuration. These
inventory areas can employ various mechanisms that feed into the
dispensing mechanism. These inventory areas can also alter to
accommodate a wide range of items in quantity and size.
[0020] The present system provides a common robotic dispensing
system to service more than one user in parallel. By providing an
isolated and centrally located mechanism, multiple users can engage
with a system simultaneously. Purchased items are queued based on
time of transaction and dispensed accordingly. This provides a
great advantage by removing the constraint of one user at a machine
at one time. This is a pronounced advantage in crowded or popular
venues, where queues may form in front of machines. The dual-sided
machine allows for almost double the users to be serviced in the
same amount of time by providing two portals for transaction and
product dispensing within a single machine platform. It also
enables greater flexibility in merchandising/designing the machine
in that each side of the machine can take on a different look/feel,
but be accessed by the same robotic mechanism.
[0021] The present system enables separation of the
purchasing/transactional components of the vending platform with
the dispensing components, allowing inventory and completion of the
process to occur in a different location from the selection of
merchandise and payment transaction. One such scenario: a physical
space is inhabited by a central dispensing mechanism that attaches
to adjacent inventory dispensing towers; users retrieve their
purchases out of multiple sides of this mechanism after completing
the transaction at screens. These screens can be integrated within
this location or located remotely.
[0022] This new centralized robotic vending mechanism increases the
flexibility in dispensing capability in product size, shape, and
orientation. In addition, it decreases the axes of motion and
potential points of error by creating a more efficient mechanism
and process of dispense. As a result, the machine's size, capacity
and shape can change without duplication of expensive robotic
components. This design also allows multiple users to
simultaneously purchase items in the machine at two different
parallel locations at the machine, while utilizing the same robotic
dispensing mechanism. This doubles the service capacity of the
machine. This also establishes a modular machine assembly
convention whereby the robotic dispensing mechanisms are housed in
one distinct section of the machine (the totem) and the inventory
sections are separate segments that can affix to the totem to
expand or contract depending on space and business considerations,
without necessitating redesign of the machine's hardware or
software.
[0023] Objects of the present system are to provide a product
vending machine, automated retail machine, or self-service machine
where items are stored inside a secure area and delivered to a user
upon a successful transaction in an automated manner.
[0024] A basic object is to provide an improved design for product
dispensing that cost effectively increases versatility, efficiency,
and reliability of the system. This includes, improved product
containment systems to increase product storage capacity, ease and
efficiency of product handling, dispensing, structural integrity,
modularity, customization, shipping/assembly, access and loading of
the machine.
[0025] Another basic object of the present system is to provide a
more effective and flexible vending machine design that can be
adapted for its deployment environment by reusing a common
dispensing component.

for a single robotic dispensing system to support multiple
iterations of inventory/storage systems in a flexible and easily
configurable/alterable manner. [0031] e) To provide a design for a

shape, etc.) in an automated retail, vending or self-service system
based on optimizing the machine for the venue, or merchandising
program. [0033] g) To provide a design for a single robotic
system/machine platform to vend items out of multiple sides of a
machine enabling more than one user to use the machine
simultaneously. [0034] h) To build a system that can efficiently
and effectively allow more than one user to use a single automated
retail store machine (or vending machine or self service machine)
concurrently. [0035] i) To provide a cost-effective system design
that increases the efficiency of product delivery by opening
multiple transaction portals in a machine that utilizes the same

increasing the surface area for products to dispense and decreasing
physical barriers (probable jam locations) within the dispensing
mechanism. [0039] m) To design a system that reduces the number of
potential moves or axes of motion (e.g. reduces robotic movement to
Y and Z vs. X, Y and Z motion) that a product and or robot need to
make in order to dispense an object in a self-service, vending,
and/or automated retail platform utilizing robotic technology.

co-inventors Darrell Scott Mockus, Mara Segal and Russell
Greenberg, and priority based on said application is claimed.
[0074] With initial reference directed to FIGS. 1A-1E of the
appended drawings, a robotized gantry 100 is adapted to be
integrated into a multiple-module vending machine or automated
retail store (see vending machine 200, FIGS. 2A and 2B). Gantry 100
comprises a rigid, upright frame consisting of an upper square
portion 101, supported by vertical upright C-Channel support beams
102 attached to a gantry base 110. An internal elevator comprises a
transverse conveyor 105 resting upon an elevator conveyor tray 107
within the gantry 100. Conveyor 105 comprises a flexible sheet
looped and entrained about a pair of spaced apart rollers 105B that
are journalled in the frame at 120 (FIG. 1D). The elevator is
supported by two brackets 109 disposed on opposite ends of conveyor
tray 107. The elevator, and thus conveyor 105 and tray 107 can be
raised or lowered using pulleys 103 (FIG. 1A) that are attached
atop the vertical support beams 102 and which entrain 9 mm wide and
3605 mm long belts 104.
[0075] Preferably conveyor tray 107 has a pair of retractable,
product collection wings 106 that open in response to wing hinge
assembly 108 when the elevator is in place to collect items that
are dispensed from inventory area(s) in modules placed on either
side of the dispensing gantry 100. Wings 106 span the distance
between the conveyor and the inventory shelves caused by the
necessary existence of the frame structure to support the conveyor
elevator.
[0076] FIGS. 1C and 1D clarify how gantry components are driven.
The conveyor belt 105 is driven by a conveyor stepper motor 111
that uses a 9 mm. wide belt 121 (FIG. 1E) to power a drive pulley
connected to a roller bar 112 and feeds the conveyor belt around
the conveyor rollers 105B that are journalled at 120. The flexible
conveyor fabric is wrapped around the conveyor drive roller 112 and
the rollers 105B.
[0077] The generally rectangular product collection wings 106 are
disposed on either side of the conveyor 105 to direct selected
products upon the conveyor to vend. The retractable wings 106 are
actuated by the wing motor 113 (514 FIG. 5) connected to the wing
hinge assembly 108 (FIG. 1A) which comprises a wing drive shaft
(124 FIG. 1F) that distributes power from the motor to a series of
levers 114 and 115 that are connected to hinges 116 secured to the
product collection wings 106. As the motor turns from the closed
position, the support levers 115 are pulled downwardly, causing the
upper portion of the levers 115 to slide within stabilizer follower
slots (FIG. 1B) in hinges 116. This opens the collection wings 106
to a predetermined width that allows the conveyor 105 to collect
products from inventory areas attached to either side of the
central gantry dispensing assembly 100. The motor can be reversed
to close the product collection wings.
[0078] The elevator motor 117 (507 FIG. 5) is connected to a pulley
wheel and uses a 9 mm. wide belt to drive the elevator drive shaft
118 turning two pulleys 129 mounted on either side of the
subassembly that drives the elevator belt 104 which loops around
the top pulleys 103 thereby raising or lowering the elevator. After
a product is collected from the inventory shelf, the elevator is
aligned with the collection area compartment behind the collection
area opening 204 (FIG. 2A) in the totem door 211 (FIG. 2A).
[0079] FIG. 1E provides additional reference for FIGS. 1A through
1D in relation to the mechanisms that drive the conveyor belt in
the robotic gantry. Parts and components have been removed for
clarity. In this view, the belt 121 that drives the pulley 122
connected to roller bar 112 is illustrated. The conveyor 105 is
threaded under roller bar 112 and over auxiliary roller bars
123.
[0080] FIG. 1F provides additional reference for FIGS. 1A through
1D in relation to the mechanisms that operate the product
collection wings 106 in the robotic gantry. Parts and components
have been removed for clarity. When motor 113 is actuated from a
closed position, drive shaft 124 rotates causing levers 125 to
rotate. This causes levers 127 that are connected to levers 125 to
contract because of their connection to hinges 126. These levers
are connected to lever 115 at point 128 pulling down forcing the
lever connection point to slide in the slot in hinge 116. Crossbar
114 keeps the power distribution even. When the motor is reversed
back to the starting position, the levers move in the opposite
direction causing the product collection wings 106 to close.
[0081] FIG. 1G provides additional reference for FIGS. 1A through
1D in relation to the mechanisms that operate the elevator in the
robotic gantry. Parts and components have been removed for clarity.
Motor 117 is connected to pulley 130 which drives belt 131
connected to pulley 132. Pulley 132 is affixed with two set screws
driven into flat spots on elevator drive shaft 118. A support 135
provides additional shaft support between the couplers. The shaft
is connected at either end to couplers 119 that deliver power to
the belt pulley mechanisms 129. The couplers 119 each have two flex
points that allow the gantry to compensate for any torque on the
assembly. The couplers 119 are helical beam couplings that each
have two sets of spiral slots, a feature that provides compensation
for parallel misalignment, angular misalignment or axial motion
issues by flexing to these forces while maintaining a connection on
both ends without compromising the coupler integrity. This way, the
machine will continue to operate even if the drive shaft gets
pulled out of alignment due to natural forces attributed to the
installation environment or through warping due to age and wear.
This feature greatly increases the mechanism's ability to perform
under structure strain and natural wear. Both ends of the elevator
belt 104 are attached to clamp 136. There is one clamp on each side
of the gantry (only one side is visible in the diagram). These
clamps are attached to supports 134. This clamp pinches the ends
each belt 104 and causes the gantry to be attached to a fixed point
on the belt. As the pulley assemblies drive the elevator belt in
either direction, the gantry raises or lowers the entire elevator
assembly accordingly. Supports 109 keep the elevator platform
level. The elevator tray has a hinge coupler support 133 that
consists of a pin and a series of rubber O-rings that fit inside a
shaft. This mechanism allows the tray to have some flexibility to
compensate for irregular weight distribution of heavy products and
natural torque that can occur because of the installation location
of the machine and wear and tear on the components that will occur
over time. This feature is assisted by the design where the
supports only connect on one side of the gantry allowing for
additional stress on the frame to occur without impeding the
elevator. There is great advantage to having this flexibility built
into the gantry mechanism as the inability to compensate for these
common forces in automated retailing installations can cause the
dispensing mechanism to fail. The alternative of providing a very
rigid support structure is cost prohibitive and can add significant
weight to the machine that in turn causes logistic issues.
[0082] With additional reference directed to FIGS. 2A and 2B, a
vending machine constructed in accordance with the best mode of the
invention has been generally designated by the reference numeral
200 (FIG. 2A). Much of the hardware details are explained in the
aforementioned pending applications that have been incorporated by
reference herein. Display module 210 can be attached with a hinge
to an inventory area covered by control panel 211, comprised of a
rigid upright cabinet, or the module 210 can be mounted to a solid
structure as a stand-alone retail display. The display module 210
forms a door hinged to an adjacent cabinet such as an inventory
cabinet 212A adjacent gantry 100 that is covered by control column
211.
[0083] A variety of door configurations known in the art can be
employed. For example, the display doors can be smaller or larger,
and they can be located on one or both sides of the control column
211. The display doors can have multiple square, oval, circular,
diamond-shaped, rectangular or any other geometrically shaped
windows. Alternatively, the display area can have one large display
window with shelves inside.
[0084] A customizable, lighted logo area 201 (FIG. 2A) is disposed
at the top of column 211. Touch screen display 202 is located below
area 201. Panel 203 locates the machine payment system, coin
acceptor machine or the like. Additionally panel 203 can secure a
receipt printer, keypad, headphone jack, fingerprint scanner or
other access device. The product retrieval area 204 is disposed
beneath the console 211 in a conventional collection area
compartment (not shown). A key lock 205, which can be mechanical or
electrical such as a punch-key lock, is disposed beneath the face
of the module 210. One or more motion sensors 214 are disposed
within smaller display tubes within the console interior. A
plurality of generally circular product viewing areas 207 and a
plurality of generally diamond shaped viewing areas 206 are defined
upon the outer the face of the casing 208 that are aligned with
internal display tubes behind the product viewing surface areas,
though the shape of the viewing areas may alter with various
merchandising concepts. However, the convention of framing
merchandising offerings is consistent to enable intuitive
interfacing whether a physical or virtual representation of the
merchandise display. The reference numeral 209 designates an
exterior antenna that connects to a wireless modem inside the
machine providing connectivity. 213 shows inventory shelves which
may be mounted in the inventory cabinet 212. These inventory
shelves may contain any mechanism such as conveyors or spiral
vending systems as long as they can push a product off the edge of
the inventory tray.
[0085] Speakers 215 are mounted in the column 211. A camera 216
capable of capturing video and still images is also mounted in the
column 211. The machine components are set on casters 217 with feet
that can be retracted for moving or lowered to position a machine
in a deployed location.
[0086] FIG. 2B shows a standard configuration of the assembly. The
robotized modular gantry 100 is shown connected to an inventory
cabinet 212A by bolting the upright C-Channel structures 102 of the
modular gantry 100 to upright C-Channel beams 219 which are then
affixed to the upright C-Channel structures 220 of the inventory
cabinet using additional bolts. Power and controls are routed to
the modular gantry via a wiring harness (not depicted) located on
the bottom of the modular gantry. The CPU and power supplies
(detailed in FIGS. 4 and 5) are located in the bottom of the main
inventory cabinet that is attached to a modular gantry. A second
inventory cabinet 212B can also be attached to the other side of
the robotized modular gantry 100 using the same method of bolting
the upright supports of the inventory cabinets 220 and the upright
supports of the gantry 102 to a common upright C-Channel support
219. Power and control cables for the additional inventory system
modules and power and control cables for the additional lighting
modules can be connected via cables with standard connectors (not
pictured).
[0087] Display doors 210 can be attached to the inventory cabinets
via a piano hinge 218 running the full height of the door. The
necessary electrical and control wiring connects via a wiring
harness 221 located on the interior of the inventory cabinet near
the hinge connection. These piano style hinges are located on the
exterior corners of the inventory cabinets. They are covered with
simple metal paneling if they are not in use. The totem doors 211
are attached in a similar manner using a piano hinge 218. The
necessary electrical and control wiring connect to a wiring harness
located in the interior of the totem door (wiring harness not
depicted).
[0088] With primary reference directed to FIG. 3, a system
consisting of a plurality of automated retail machines connected
via a data connection to a centralized, backend operations center
system has been designated by the reference numeral 300. At least
one automated retail machine 301 is deployed in a physical
environment accessible by a consumer who can interact with the
machine 301 directly. There can be any number of machines 301, all
connected to a single, remote logical operations center 330 via the
Internet 320 (or a private network). The operations center 330 can
physically reside in a number of locations to meet redundancy and
scaling requirements.
[0089] The machine software is composed of a number of segments
that all work in concert to provide an integrated system. Logical
area 302 provides the interface to deal with all of the machine's
peripherals such as sensors, keypads, printers and touch screen.
Area 303 handles the monitoring of the machine and the
notifications the machine provides to administrative users when
their attention is required. Area 304 controls the reporting and
logging on the machine. All events on the machine are logged and
recorded so they can be analyzed later for marketing, sales and
troubleshooting analysis. Logical area 305 is responsible for
handling the machine's lighting controls.
[0090] Logical area 306 is the Inventory Management application. It
allows administrative users on location to manage the inventory.
This includes restocking the machine with replacement merchandise
and changing the merchandise that is sold inside the machine.
Administrative users can set the location of stored merchandise and
the quantity.
[0091] Logical area 307 is the retail store application. It is the
primary area that consumers use to interface with the system.
Logical area 308 handles the controls required to physically
dispense items that are purchased on the machine or physically
dispense samples that are requested by a consumer. This area reads
the data files that tell the machine how many and what types of
inventory systems are connected to the machine. Logical area 309
controls the inventory management system allowing authorized
administrative users to configure and manage the physical inventory
in the machine. Area 310 controls the payment processing on the
machine. It manages the communication from the machine to external
systems that authorize and process payments made on the machine.
Area 311 is an administrative system that allows an authorized user
to manage the content on the machine. This logical area handles the
virtual administrative user interface described previously. The
content can consist of text, images, video and any configuration
files that determine the user's interaction with the machine.
[0092] The latter applications interface with the system through an
application layer designated in FIG. 3 by the reference numeral
312. This application layer 312 handles the communication between
all of these routines and the computer's operating system 313.
Layer 312 provides security and lower level messaging capabilities.
It also provides stability in monitoring the processes, ensuring
they are active and properly functioning. Logical area 331 is the
user database repository that resides in the operations center 330.
This repository is responsible for storing all of the registered
user data that is described in the following figures. It is
logically a single repository but physically can represent numerous
hardware machines that run an integrated database. The campaign and
promotions database and repository 332 stores all of the sales,
promotions, specials, campaigns and deals that are executed on the
system. Both of these databases directly interface with the
real-time management system 333 that handles real-time requests
described in later figures. Logical area 334 aggregates data across
all of the databases and data repositories to perform inventory and
sales reporting. The marketing management system 335 is used by
administrative marketing personnel to manage the marketing
messaging that occurs on the system; messages are deployed either
to machines or to any e-commerce or digital portals. Logical area
336 monitors the deployed machines described in FIG. 2, and
provides the tools to observe current status, troubleshoot errors
and make remote fixes. Logical area 337 represents the general user
interface portion of the system. This area has web tools that allow
users to manage their profiles and purchase products, items and
services. The content repository database 338 contains all of the
content displayed on the machines and in the web portal. Logical
area 339 is an aggregate of current and historical sales and usage
databases comprised of the logs and reports produced by all of the
machines in the field and the web portals.
[0093] FIGS. 4 and 5 illustrate system wiring to interconnect with
a computer 450 such as Advantech's computer engine with a 3 Ghz
CPU, 1 GB of RAM memory, 320 GB 7200 RPM hard disk drive, twelve
USB ports, at least one Serial port, and an audio output and
microphone input. The computer 450 (FIGS. 4 and 5) communicates to
the lighting system network controller via line 479. Through these
connections, the lighting system is integrated to the rest of
system. Power is supplied through a plug 452 that powers an outlet
453, which in turn powers a UPS 454 such as TripLite's UPS (900 W,
15 VA) (part number Smart1500LCD) that conditions source power,
which is applied to input 455 via line 456. Power is available to
accessories through outlet 453 and UPS 454.
[0094] Computer 450 (FIG. 4) is interconnected with a conventional
payment reader 458 via cabling 459. A pin pad 485 such as Sagem
Denmark INT1315-4240 is connected to the CPU 450 via a USB cable.
An optional web-accessing camera 461 such as a LOGITECH webcam
(part number 961398-0403) connects to computer 450 via cabling 462.
Audio is provided by transducers 464 such as Happ Controls
four-inch speakers (part number 49-0228-00R) driven by audio
amplifier 465 such a Happ Controls Kiosk 2-Channel Amplifier with
enclosure (part number 49-5140-100) with approximately 8 Watts RMS
per channel at 10% THD with an audio input though a 3.5 mm. stereo
jack connected to computer 450. A receipt printer 466 such as
Epson's EU-T300 Thermal Printer connects to the computer 450 via
cabling 467. The printer is powered by a low voltage power supply
such as Epson's 24 VDC power supply (part number PS-180). A remote
connection with the computer 450 is enabled by a cellular link 470
such as Multitech's Verizon CDMA cellular modem (part number
MTCBA-C-IP-N3-NAM) powered by low voltage power supply 472. The
cellular link 470 is connected to an exterior antenna 209. A touch
enabled liquid crystal display 474 such as a Ceronix 22''Widescreen
(16:10) Touch Monitor for computer operation also connects to
computer 450. A Bluetooth adapter 487 such as D-Link's DBT-120
Wireless Bluetooth 2.0 USB Adapter is attached to the CPU allowing
it to send and receive Bluetooth communication. A wireless router
488 such as Cisco-Linksys' WRT610N Simultaneous Dual-N Band
Wireless Router is connected to the CPU to allow users to connect
to the machine via a private network created by the router.
[0095] Digital connections are seen on the right of FIG. 4.
Gantry-Y (conveyor elevator), stepper motor controller such as the
Arcus Advanced Motion Driver+Controller USB/RS485 (part number
Arcus ACE-SDE) connection is designated by the reference numerals
476. 477 connects to the conveyor motor controller which can also
be something similar to an Arcus Advanced Motion Driver+Controller
USB/RS485 (part number Arcus ACE-SDE). Dispenser control output is
designated by the reference numeral 478 which operates the product
collection wings motor 113 (FIG. 1B). The LED lighting control
signals communicate through USB cabling to a DMX controller 479
that transmits digital lighting control signals in the RS-485
protocol to the display tube lighting circuit board arrays. An
ENTTEC-brand, model DMX USB Pro 512 I/F controller is suitable.
Cabling 480 leads to vending control. One or more inventory systems
can be connected to the vending control depending on the
configuration. Dispenser door control is effectuated via cabling
481. Facade touch sensor inputs arrive through interconnection 482.
Motion sensor inputs from a motion sensor such as Digi's
Watchport/D (part number Watchport/D 301-1146-01) are received
through connection 483. A USB connection connects the product
weight sensor 484 such as Sartorius (part number FF03 VF3959) that
is located in the collection area to determine the presence of a
dispensed item.
[0096] FIG. 5 illustrates a detailed power distribution arrangement
500. Because of the various components needed, power has to be
converted to different voltages and currents throughout the entire
system. The system is wired so that it can run from standard 110
V.A.C. power used in North America. It can be converted to run from
220 V.A.C. for deployments where necessary. Power from line-in 455
supplied through plug 452 (FIG. 4) powers a main junction box 453
with multiple outlets (FIG. 4, 5) that powers UPS 454 which
conditions source power, and outputs to computer 450 line 456.
Power is available to accessories through main junction box 453 and
Ground-fault current interrupt AC line-in 455. An additional AC
outlet strip 501 such as Triplite's six position power strip (part
number TLM606NC) powers LED lighting circuits 502 and a touch
system 503. Power is first converted to 5 volts to run the lighting
board logic using a converter 540. Another converter, 541, converts
the AC into 24 Volt power to run the lights and touch system.
[0097] An open frame power supply 505 (FIG. 5) provides 24 VDC, 6.3
A, at 150 watts. Power supply 505 powers Y-controller 506 such as
the Arcus Advanced Motion Driver+Controller USB/RS485 (part number
Arcus ACE-SDE), that connects to Y axis stepper motor 507 (117
FIGS. 1C & 1D). A suitable stepper 507 can be a Moons-brand
stepper motor (part number Moons P/N 24HS5403-01N). Power supply
505 also connects to a conveyor controller 508, which can be an
Arcus-brand Advanced Motion Driver+Controller USB/RS485 (part
number Arcus ACE-SDE), that connects to a conveyor stepper 509 (111
in FIG. 1C and FIG. 1D). A Moons-brand stepper motor (part number
Moons P/N 24HS5403-01 N) is suitable for stepper 509.
[0098] Power supply 505 (FIG. 5) also powers dispenser controller
510, dispenser door control 511, and vending controller 512.
Controller 510 powers collection wing motor 514 (113 FIGS. 1C and
1D) and door motor 515. Motors 514 and 515 can be Canon-brand DC
gear motors (part number 05S026-DG16). Controller 512 operates
conveyor motors 516 such as Micro-Drives DC Gear Motor (Part Number
M32P0264YSGT4). The logo space 201 (FIG. 2) is illuminated by
lighting 518 (FIG. 5) powered by supply 505. Supply 505 also powers
LCD touch screen block 520 (FIG. 5) such as a Kristel
22''Widescreen (16:10) LCD Touch Monitor with USB connection for
the touch panel. UPS 454 (FIG. 5) also powers an AC outlet strip
522 that in turn powers a receipt printer power supply 523 such as
Epson's 24 VDC power supply (part number PS-180) that energizes
receipt printer 524 such as Epson's EU-T300 Thermal Printer, an
audio power supply that powers audio amplifier 527 such a Happ
Controls Kiosk 2-Channel Amplifier with enclosure (part number
49-5140-100), and a low voltage cell modem power supply 530 that
runs cellular modem 531 such as Multitech's Verizon CDMA cellular
modem (part number MTCBA-C-IP-N3-NAM). A proximity sensor 214 (FIG.
2) such as a Digi Watchport/D part number 301-1146-01 is connected
to the CPU 450. 532 is a door sensor and actuator such as Hamlin's
position and movement sensor (part 59125) and actuator (part 57125)
which are connected to the CPU 450.
[0099] Subroutine 600 (FIG. 6) illustrates the preferred method of
initializing the machine and inventory and dispensing system at
system runtime. The process begins at step 601 when the system
application is launched. Step 602 reads in and parses the lighting
XML file 603. The lighting file contains a sequence of lighting
sequences to be performed for various user actions on the system
such as selecting a product or category, adding to the virtual
shopping bag and removing it from the shopping bag. These lighting
sequences dictate both the onscreen coloring of products in the
virtual display and the lighting of products in the physical
display. These values are cached in local memory as an application
variable. Step 604 checks if there are any fatal errors. Fatal
errors are ones that prevent the system from allowing a user to
complete a transaction. All errors are logged using the reporting
and logging system 303 (FIG. 3). Non-fatal errors are noted in the
log file so they can be examined later to correct the issue. If the
error is fatal, the process goes to step 605 where the user is
notified of an error and given customer support information and an
alert notification is sent out to the notification system 303 (FIG.
3). The system is placed in an idle state where the touch screen
will display a message noting that the machine is currently not in
service. The system will attempt to recover in step 606 by
attempting to start the application process again and reinitialize
the system. If there are no fatal errors, the process continues to
step 607 that reads in and parses the planogram file 608. The
planogram file contains the product identification number, or item
identification number, a product name and a Boolean value if it is
active or not for each display slot number. These values are cached
in local memory as an application variable. Step 609 checks if
there are any fatal errors. If there are fatal errors, it routes to
step 605, otherwise the process continues at step 610. Step 610
reads in all of the inventory XML files. These files instruct the
system on what inventory cabinets are attached to the machine and
what inventory is in what inventory slots. Each inventory slot is
designated by the cabinet it is located in, the shelf it is on, the
size of the inventory slot and the motors that drive the dispensing
mechanism. Using this information, the application can determine
the shelf location (height). The XML file information is cached and
then accessed during product dispensing to guide the robotic gantry
elevator to the correct shelf height to collect a product.
[0100] The dispensing motor information is used by the dispenser
control to turn on the motor that dispenses the product until a
mechanical switch is activated determining the product has been
dispensed to the gantry elevator. Because of the centralized layout
of the robotic gantry, it does not matter which inventory system is
connected or even what side from which the product is being
dispensed. It only matters what shelf the product is on so the
elevator can move to the correct height to collect the product.
Step 610 reads in all of the screen templates 611 that determine
the layout of the visual selection interface. Step 612 checks if
there are any fatal errors. If there are fatal errors, it routes to
step 605, otherwise the process continues at step 613. Step 613
reads in all of the screen templates 611 that determine the layout
of the user interface and all of the screen asset files 614
associated with the screen templates 611.
[0101] These asset files can be images or extended markup files
that represent buttons, header banners graphics that fit into
header areas, directions or instructions that are displayed in
designated areas, image map files that determine which area on an
image corresponds represents which area on the physical facade or
images representing the physical facade. These assets are cached
into local memory in the application. Step 615 checks if there are
any fatal errors. If there are fatal errors, it routes to step 605,
otherwise the process continues at step 616. Step 616 reads and
parses the product catalog files 617. The product catalog stores
all of information, graphics, specifications, prices and rich media
elements (e.g. video, audio, etc.) for each item or product in the
system. Each element is organized according to its identification
number. These elements can be stored in a database or organized in
a file folder system. These items are cached in application memory.
Step 618 checks if there are any fatal errors. If there are fatal
errors, it routes to step 605, otherwise the process continues at
step 619. Step 619 reads in all of the system audio files 620 and
the file that the stores the actions with which each audio file is
associated. Audio files can be of any format, compressed or
uncompressed such as WAV, AIFF, MPEG, etc. An XML file stores the
name of the application event and the sound file name and location.
Step 621 checks if there are any fatal errors. If there are fatal
errors, it routes to step 905, otherwise the process continues at
step 622. Step 622 does a system wide hardware check by
communicating with the system peripherals and controllers 302 and
308 (FIG. 3). Step 623 checks if there are any fatal errors. If
there are fatal errors, it routes to step 605, otherwise the
process continues at step 624. Step 624 launches the application
display on the touch screen interface. The system then waits for
user input 625.
[0102] Subroutine 700 (FIG. 7) illustrates the preferred runtime
method the machine uses to dispense items to an end user during a
user session. The process begins at step 701 after a user completed
a transaction that purchases the merchandise about to be vended.
This process assumes that a separate process has already checked
that the inventory is available for vending and it has been paid
for. The routine is passed a list of items to be dispensed. For
items that have multiple quantities, each item is listed as a
separate item. Step 702 reads this list into the process memory.
Step 703 determines if the dispensing system is busy processing
another request. If the dispensing system is busy for any reason,
step 704 pings the resource until it is free and then directs the
process to step 708 where the first (or next) item in the list is
read. Step 705 is a timer that monitors step 704 to determine if
the wait for the resource times out to a preset time. If it does
time out, the process is considered to have an error and it directs
control to step 706 that sends out an alert using the notification
system designated by 303 (FIG. 3). Step 707 attempts the recovery
of the system by running any preprogrammed diagnostics and self
repairing routines that check and restart power and communication
links to the system. If the system cannot automatically recover,
the machines goes into an idle state and a message is displayed on
the main screen indicating the machine is currently out of service
preventing users from using the system. If the system resources are
free, step 708 reads the next item to be vended from the list and
retrieves its associative information into memory. This information
was originally loaded into the system as the inventory XML file 611
(FIG. 6) read into memory in step 610. The item, or product id is
used to retrieve this information. Information associated with the
identification number includes the item's location in the inventory
system (shelf height and corresponding elevator position
represented as the position the elevator needs to be in to properly
collect the dispensed product), the dispensing motors associated
with vending the item from the inventory shelf and item details
such as its name to prompt the user, and its weight and dimensions
which are used in conjunction with the product weight sensor 484
(FIG. 6) to determine a successful vend.
[0103] Step 709 uses this information to move the elevator tray
assembly 107 (FIG. 1A) to the correct shelf height for the current
item being vended. The elevator height is determined by preset
position values that tell the stepper motor where to position
itself on the vertical aspect of the gantry. The stepper motor has
an encoder that communicates with the controller to verify the
position. This combination of hardware allows the software to set a
height value and have the stepper motor and the stepper controller
ensure the correct position is attained. If there is a detectable
error with the elevator mechanics, an error message is generated
and sent out by step 706. Step 707 will again try to recover if
possible. If the elevator assembly reaches the correct height and
position as designated by the product information record, the
product collection wings 106 (FIGS. 1A and 1B) are expanded to
create an extended landing area that will catch products coming off
the inventory trays 213 (FIG. 2). If an error in this process is
detected, an error message is generated and step 706 will send out
an alert. Otherwise, if the elevator is in position and the
production collection wings are extended, step 711 will use the
information retrieved in the product record to activate the
motor(s) associated with that item of inventory. A mechanical
switch is used to indicate that the motor has revolved enough times
to properly dispense the product or item off the shelf at which
point it falls on to the product collection wings and into the
conveyor 105 (FIGS. 1A and 1B). Errors are again detected if
present and routed to the notification system in step 706. Step 712
retracts the product collection wings so the elevator can freely
move up and down in the dispensing assembly. This step also assists
in positioning the product on the conveyor where it can be
delivered to the user later in the process. Any detected errors in
this step are routed to step 706. If there are no errors, step 713
moved the elevator gantry to the user collection area. The movement
of the elevator mechanically opens up the product collection area
by activating levers that open the top and back of the area. If no
errors are detected, step 714 notes which control activated the
dispensing process. This is only relevant when the machine is
configured for dual sided vending (see FIGS. 9 and 11). Step 715
then spins the conveyor in the direction of the user that initiated
the dispensing process. If no errors were detected, step 716
repositions the elevator that reverses the mechanical operation
that opened the back of the collection area and closed it sealing
off the internal components of the machine from the user. If no
errors were detected, step 717 turns on the lights in the
collection area 204 (FIG. 2) and opens the exterior collection area
door. Step 718 prompts the user on the screen 202 (FIG. 2) to
collect their product. Step 719 monitors signals from the product
weight sensor 484 (FIG. 4) records the weight and matches it
against the product weight information stored in the inventory XML
file 611 (FIG. 6). This sensor could also be a motion or light
curtain sensor. If the item was not removed for a preset amount of
time, the user is prompted again to collect their item in step 718.
If user does not collect their product after a set number of
attempts, an error is generated. If the sensor determines the user
has removed their item, the process continues to step 720 where the
exterior door is closed and the product collection area lights are
turned off. The system again monitors for any mechanical errors in
this process (line to step 706 not shown). Step 721 determines if
there are any additional items in the list of items to be vended.
If there are additional items to be vended, the process routes back
to step 703 where it begins again for the next item. If there are
no more items to be vended, the process ends at step 722.
[0104] With reference directed to FIG. 8, an alternative vending
machine 800 constructed in accordance with the best mode of the
invention incorporates a variant on the display module designated
as 210 in FIG. 2A. In this version the display module has a
plurality of generally square product viewing areas 801 that
present an alternative display, different from the diamond and
circle display windows designated at 206 and 207 respectively in
FIG. 2A.
[0105] With reference directed to FIG. 9, an alternative 900 (FIG.
9) shows an alternative configuration of the machine where it has
been outfitted to dispense merchandise out of both the front and
back of the machine. This machine has display modules 210 affixed
to both sides of the inventory cabinet 212. It also has a vertical
control column 211 affixed to both sides of the central robotic
gantry 100. This configuration allows the unit to serve two people
at the same time.
[0106] With reference directed to FIG. 10, alternative machine 1000
represents a similar configuration but with only one inventory
cabinet 212 and display module 210. These are once again attached
to the common centralized robotic dispensing gantry 100. In this
configuration a simple metal plate 1001 (not shown) cut the size of
the dispensing system tower is affixed to the side where the
inventory cabinet was attached in FIG. 8 using the same bolts to
secure the system.
[0107] With reference directed to FIG. 11, another configuration of
a vending machine 1100 utilizes the centralized robotic dispensing
gantry 100 with one inventory cabinet and two display modules 210
and two vertical control columns 211. As in FIG. 9, this
configuration allows for two users to simultaneously interact with
the machine while using only one robotic dispensing mechanism and
sharing a common inventory cabinet.
[0108] It will be understood that certain features and
subcombinations are of utility and may be employed without
reference to other features and subcombinations. This is
contemplated by and is within the scope of the claims.
[0109] As many possible embodiments may be made of the invention
without departing from the scope thereof, it is to be understood
that all matter herein set forth or shown in the accompanying
drawings is to be interpreted as illustrative and not in a limiting
sense.
