BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to airport baggage handling and, more particularly, to a baggage handling system and associated method for providing users with an efficient manner of sorting and processing baggage from air travel.
2. Prior Art
Travel, for much of human history, was a luxury and delight, an extravagance limited to the upper classes, or a hardship undertaken by poor but hopeful immigrants or refugees. Not so many generations past, people with the money and time could travel to Europe by ocean liner, hauling along three months worth of clothes in a couple of steamer trunks the size of office desks. No more. These days, travel is less pleasure than harrowing necessity for much of the working world, less high adventure than vocational ordeal.
Consider that in 2005, a total of 2.8 million articles of luggage were lost by airline travelers (which is to say lost by the airlines) leading not only to loss of valuables ranging from personal jewelry to business documents but inconvenience, delay, and frustration. Bags are x-rayed for security, sometimes opened and physically searched, and frequently lost or misdirected, causing us inconvenience at best and a ruined trip at worst. Nonetheless, we have to travel; it's part of contemporary business life, like the bizarre spectacle of airport terminals where thousands of harried people, chattering into headset cell phones, appear to be talking to themselves.
The amazing thing about airline baggage is not that so much is lost, but that the overwhelming majority of it gets to its destination, and is there to meet you at the baggage carousel. Sophisticated automated systems, “smart” conveyors; Destination Coded Vehicles or DCV's, which travel at high speed along complex webs within the heart of the terminal; and computerized tracking, sorting, and routing devices, play an ever larger part in handling and directing baggage. Unseen by travelers, these systems move baggage swiftly and efficiently through the underworld of the terminal. But in the end, sorting and loading your bags onto the right lane is the province of human baggage handlers, a labor force. Like any human labor force, baggage handlers can make mistakes, go on strike, and cost the airlines spiraling wages and health care expenditures, all expenses that automation would eliminate. Since the airlines underwent deregulation in 1978, profit margins have been thin, and cost-cutting measures constant. For the airlines and the airline travelers, then, complete baggage handling automation would appear to be highly desirable.
Accordingly, a need remains for a system in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a baggage handling system that is convenient and easy to use, lightweight yet durable in design, and designed for providing users with an efficient means of sorting and moving baggage throughout an airport.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide an automated airport baggage handling system. These and other objects, features, and advantages of the invention are provided by an automated airport baggage handling system including a mobile baggage transport can capable of being transported with baggage between remote locations, a stationary baggage transport conveyor adapted to transport the baggage in a predefined path, a communication link, a controller communicatively coupled to the baggage transport can and the baggage transport conveyor via the communication link, and a mobile robotic device remotely controlled by the controller via the a communication link.
The system may further include a stationary guide track located adjacent to the baggage transport can and the baggage transport conveyor, a plurality of first sensors removably located at the baggage transport can, the baggage transport conveyor, the robotic device and the guide track respectively. Notably, each of the sensors identify a location thereof relative to other the sensors respectively. A plurality of second sensors is capable of being removably attached to the baggage. In this manner, the controller causes the robotic device to be displaced along the guide track in such a manner that the robotic device accesses the baggage transport can and thereafter accesses the transport conveyor while remaining positioned along the guide track.
In one embodiment, the robotic device may be responsive to instruction signals transmitted by the controller. The controller may be responsive to feedback signals transmitted by the robotic device and the controller automatically modifies the instruction signals based upon a learned sequence of the feedback signals.
In one embodiment, the controller may include a hand-held user interface adapted to be worn by a user, a control center adapted to be operated by a non-user or a combination thereof respectively.
In one embodiment, the controller may include a processor, and a memory communicatively linked to the processor. Such a memory preferably includes a computer software program including a first executable control logic algorithm, when executed by the processor, causes the robotic device to load and unload the baggage from each of the baggage transport can and the baggage transport conveyor.
In one embodiment, the first executable control logic algorithm preferably includes the chronological steps of: registering an initial location of the first sensors relative to each other and thereby mapping a plurality of axes defining alternate travel paths for the robotic device; detecting an initial location of the second sensors relative to the first sensors; and instructing the robotic device to transport each of the second sensors from a first group of the first sensors to a second group of the first sensors such that the baggage is transported from the baggage transport can to the baggage transport conveyor.
In one embodiment, the robotic device may include a telescopic base, a plurality of telescopic armatures attached to the telescopic base, and a scanner located at the telescopic armatures. In this manner, the scanner is capable of scanning an identification barcode attached to the baggage.
In one embodiment, selected ones of the instruction signals cause the robotic device to move along the guide track to access the first and second sensors.
In one embodiment, selected ones of the feedback signals notify the controller whether the identification barcodes are recognized as one of authorized and unauthorized identification barcodes.

Thus, the following claims are incorporated into the Detailed Description, with each claim standing on its own as defining separately claimed subject matter.
The below disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments which fall within the true scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
The system of this invention is referred to generally in FIGS. 1-6 by the reference numeral 10 and is intended to provide an automated baggage transport system It should be understood that the automatic baggage transport system 10 may be used to transport luggage in many different types of baggage transport environments.
An automated airport baggage handling system 10 preferably includes a mobile baggage transport can 11 capable of being transported with baggage between remote locations such as from an airplane to a baggage retrieval location. A stationary baggage transport conveyor 12 is adapted to transport the baggage in a predefined path such as a linear conveyor 12 belt that displaces baggage from the can 11 to the baggage retrieval location, for example. A communication link 14 such as a dedicated wireless communication remotely couples a controller 15 to the baggage transport can 11 and the baggage transport conveyor 12. Such a communications link 14 may include various wireless protocols, the Internet, cellular network systems, etc. A mobile robotic device 16 is remotely controlled by the controller 15 via the communication link 14 base 25 on instructions transmitted from the controller 15. The combination of such claimed elements provides an unpredictable and unexpected benefit of automatically and remotely instructing the robotic device 16 to transport the baggage without direct human involvement, which solves the problem of paying several human employees to perform the baggage transporting tasks.
The system 10 may further include a stationary guide track 17 located adjacent to the baggage transport can 11 and the baggage transport conveyor 12. Examples of the guide track 17 may include magnetic and/or motorized guide tracks 17 that are activated and deactivated via the remotely located controller 15. A plurality of first sensors 18 may be removably located at the baggage transport can 11, the baggage transport conveyor 12, the robotic device 16 and the guide track 17 respectively. One skilled in the art understands such sensors 18 may be calibrated to detect and report the locations of the aforementioned components of the present invention. The locations may be reported to a GPS system 10 and monitored in real-time for tracking by the controller 15. Such locations may be displayed via a graphical user interface wherein a user may visually monitor movement of the aforementioned components without physically present at the job site, for example. Of course, such location reporting tasks may be performed in a manner well known by one skilled in the art.
Notably, each of the first sensors 18 identifies a location thereof relative to other first sensors 18 respectively. In this manner, the controller 15 receives and maps the GPS signals into a grid for each job site thereby enabling the user to learn the latitudinal/longitudinal size of the job site. A plurality of second sensors 19 may be removably attached to the baggage. Such sensors 19 may operate in a manner similar to the first sensors 18 for identifying and reporting the location of each baggage as it moves from one location to another. In this manner, the controller 15 causes the robotic device 16 to be displaced along the guide track 17 in such a manner that the robotic device 16 accesses the baggage transport can 11 and thereafter accesses the transport conveyor 12 while remaining positioned along the guide track 17. The combination of such claimed elements provides an unpredictable and unexpected benefit of remotely instructing the robotic device 16 to seek and retrieve each baggage within the can 11 or conveyor 12 such that no baggage is left behind, which solves the problem of human error that overlooks small bags during the baggage transport process.
In one embodiment, the robotic device 16 may be responsive to instruction signals transmitted by the controller 15. Such instruction signals are continuously transmitted by the controller 15 until each second sensor 19 is displaced from a starting zone to an ending zone. The controller 15 may be responsive to feedback signals transmitted by the robotic device 16 and the controller 15 automatically modifies the instruction signals based upon a learned sequence of the feedback signals. For example, during real-time baggage transport, the robotic device 16 notifies the controller 15 of the progress. When a predetermined number of bags are moved from the can 11 to the conveyor 12, a feedback signal may be transmitted to the controller 15 for visually depicting the real-time progress of the task. In this manner, the robotic device 16 may be retrofitted with communications devices 22 that are interfaced with the communications link 14, in a manner well known in the industry. The combination of such claimed elements provides an unpredictable and unexpected benefit of keeping real-time track of the baggage transport progress, which solves the problem of not knowing which bags are misplaced.
In one embodiment, the controller 15 may include a hand-held user interface 15a adapted to be worn by a user. Alternately, the controller 15 may include a control center operated by a non-user. Yet another embodiment may include a combination of the hand-held user interface 15a wherein a user may monitor the baggage transport process from a local site while the control center 15 monitors several baggage transport processes from a remote site.
In one embodiment, the controller 15 may include a processor 20, and a memory 21 communicatively linked to the processor 20. Such a memory 21 preferably includes a computer software program including a first executable control logic algorithm, when executed by the processor 20, causes the robotic device 16 to load and unload the baggage from each of the baggage transport can 11 and the baggage transport conveyor 12. Again, the robotic device 16 is controlled via the instructions signals transmitted from the controller 15. In addition, the robotic device 16 is capable of transmitting feedback signals in a manner well known in the industry such the user and/or control center maintains an up to date database of information associated with baggage transport.
In one embodiment, the first executable control logic algorithm preferably includes the chronological steps of: registering an initial location of the first sensors 18 relative to each other and thereby mapping a plurality of axes 23 defining alternate travel paths 13 for the robotic device 16. Such initial locations thereby define a grid, for example, wherein the controller 15 is able to learn the physical dimensions of the job site. Such dimensions may be identified along x, y and z axes, for example. Another step may include detecting an initial location of the second sensors 19 relative to the first sensors 18 whereby the controller 15 is able to calculate the distance and direction to move the robotic device 16 for accessing and retrieving the bags. Another step may include instructing the robotic device 16 to transport each of the second sensors 19 from a first group (located at the can 11) of the first sensors 18 to a second group (located at the conveyor) of the first sensors 18 such that the baggage is transported from the baggage transport can 11 to the baggage transport conveyor 12. Once the first sensors 18s are categorized into first and second groups, each being associated with either the can 11 or the conveyor 12, the controller 15 is able to calculate the estimated number of iterations necessary to transporting all the bags from the can 11 to the conveyor 12, for example. The combination of such claimed elements provides an unpredictable and unexpected benefit of understanding an estimated total time to finish the job, which solves the problem of not knowing how much time to allocate for baggage transport at the job site.
In one embodiment, the robotic device 16 may include a telescopic base 25, a plurality of telescopic armatures 26 attached to the telescopic base 25, and a scanner 28 located at the telescopic armatures 26. In this manner, the scanner 28 is capable of scanning an identification barcode 30 attached to the baggage. The telescopic base 25 and armatures 26 may be activated via conventional actuators and communication devices 22 incorporated within the robotic device 16, in a manner well known in the industry. Likewise, the scanner 28 may be interfaced with the communications link 14 for transmitting real time baggage data to the controller 15. As an example, selected ones of the feedback signals notify the controller 15 whether the identification barcodes 30 are recognized as one of authorized and unauthorized identification barcodes. Thus, the controller 15 quickly learns whether a bag has been accidentally misplaced or sent to a wrong can 11 and/or conveyor 12.
In one embodiment, selected ones of the instruction signals cause the robotic device 16 to move along the guide track 17 to access the first and second sensors 18, 19. As noted hereinabove, the robotic device 16 may be transported along the guide track 17 as needed to retrieve and transport the bags from the can 11 to the conveyor 12.
The user interface 15a may include a variety of stand-alone or shared devices that are capable of generating and transmitting a control signal upon receiving a user input. For example, exemplary user interface 15a devices may include a remote controller 15 employing RF, infra-red, acoustic or cellular technology, as well known in the industry. In alternate embodiments, the user interface 15a may include a handheld computer, a PDA, a cell phone, a keyboard, a mouse, etc. that may be comprised of commercially available hardware and software operating systems, for example. The aforementioned user interfaces are intended to represent a broad category of exemplary user interfaces capable of functioning in accordance with the present invention. Of course, the user interface 15 as may include other components, peripherals and software applications provided they are compatible and capable of cooperating with remaining devices of the present invention. In addition, the user interfaces may include information, documents, data and files needed to provide functionality and enable performance of methodologies in accordance with an exemplary embodiment of the invention.
As a non-limiting example, a user may instruct the controller 15 to program the robotic device 16 to load and unload bags out of various types of cans 11 and onto various types of conveyors 12. The controller 15 may then communicate with the robotic device 16 and relay commands. The robotic device 16 would then retrieve baggage from an airport luggage can 11 and sort the baggage. Finally, the baggage would be loaded onto the appropriate luggage conveyor 12. Some of the system 10 capabilities may include: loading a flight with multiple different destinations, scanning bags to determine weight and destination, loading up to four flights simultaneously.
In an alternative embodiment, the baggage handling system 10 could be designed to serve other types of infrastructure. The system 10 could be adapted to fit train stations, bus stations, and/or shipping ports. This would allow users to handle baggage for nearly any kind of transportation and ensure that the benefits would extend to the entire industry.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention. In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation.
