TITLE: BAGGAGE CHECKING DEVICE AND METHOD

The invention relates to a baggage checking device and method for checking a piece of baggage.

BACKGROUND

5

Airport passenger check-in procedures generally involve the checking and handling of baggage prior to flight boarding. This transaction usually involves interaction between a passenger and an airline representative. It is also possible that the transaction be fully automated, thereby obviating the need for an airline representative. During baggage 10 checking, the baggage may be measured and weighed by sensors configured thereto. Further, the baggage is also registered to the passenger and a label or tag affixed to it having the information to link the specific piece of baggage to a specific passenger, and to enable its routing through a baggage collection element.

Once a piece of baggage is placed on the baggage collection element, it is routed and 15 loaded into the correct cart for subsequent loading into the corresponding plane. The routing is highly automated, scanners read the baggage-identifying tags to effect the routing and therefore supervision is minimal or non-existent.

Access to the baggage collection and routing area is restricted to personnel associated with the baggage handling and checking procedure. However, incidents may occur in which an 20 individual is able to access and remain on the baggage collection area without being noticed by airline staff or airport security officers. It is possible that a child or infant or any other individual may step on an infeeding belt and be inadvertently taken to the main baggage conveyor area.

This can lead to dangerous situations, such as an individual being conveyed by a baggage 25 conveying system into automated baggage handling, checking and sorting facilities, where the baggage may be subjected to X-ray scanning, automated handling by mechanical devices, et cetera, where overexposure to X-rays or accidents may occur once the individual reaches, for example, a hydraulics area or a chute area of the conveyor belt.

Furthermore, such security weaknesses could be exploited by individuals with criminal intent 30 to gain access to the baggage collection element area or to the checked bags being transported thereon.

Therefore, a need exists for a baggage checking system that addresses said security deficiencies.

SUMMARY OF THE INVENTION 5

It is an object of the present invention to provide a device and method for safely checking baggage at an airport baggage checking station.

According to the present invention, a checking device and method are provided for checking baggage presented by a passenger or individual to an airline representative at a baggage 10 checking station. Once an airline representative or other authorized individual approves a piece of baggage for checking, the piece of baggage is placed on a baggage presentation area. The baggage presentation area may be an area on an infeeding conveyor. The airline representative or authorized individual submits a command input at an input device having an input mechanism, which input device is arranged to, in response to the command input, 15 send an instruction signal to a controlling device. Upon receipt of the instruction signal, the controlling device sends a signal for actuating the infeeding conveyor and baggage access gate. The piece of baggage is then conveyed on the infeeding conveyor, and the baggage access gate is opened, allowing passage of the piece of baggage and permitting its transfer onto the baggage collection element. The baggage collection element may be a baggage 20 collection conveyor belt, a series of conveyor belts, or any other element suitable for collection and transfer of baggage from infeeding conveyor to a destination in the airport.

Because of controlled timing and duration of the opening and closing of the baggage access gate and of the infeeding conveyor, as provided by the baggage checking device, it 25 becomes very difficult for an individual to gain unauthorized access, whether intentional or not, to a restricted area behind the baggage access gate.

Because of controlled timing and duration of the opening and closing of the baggage access gate and of the infeeding conveyor as provided by the baggage checking method, as with 30 the baggage checking device, the same or similar effects may be achieved and it becomes very difficult for an individual to gain unauthorized access, whether intentional or not, to a restricted area behind the baggage access gate.

In accordance with an embodiment of the invention, a device for checking baggage is 35 provided, comprising an infeeding conveyor having a direction of conveyance and arranged to convey a piece of baggage from a baggage presentation area to a baggage collection element, a baggage access gate movable between an open position and a closed position -3- and arranged to control passage of a piece of baggage from the infeeding conveyor to a baggage collection element, an input device having an input mechanism and configured to send an instruction signal, a controlling device connected to the input device and arranged to send signals to the infeeding conveyor and a baggage access gate, wherein, in response 5 to the instruction signal from the input device, the controlling device sends an activation signal to the infeeding conveyor and the baggage access gate, which activation signal actuates the infeeding conveyor and baggage access gate, thereby causing the piece of baggage to be conveyed from a baggage presentation area through a baggage access gate and onto a baggage collection element.

10 The input device, which is activatable by an operator and receives commands from an operator such as an airline representative and may be located at passenger check-in station or baggage checking station and may be stationary, or portable and remotely operated. The input mechanism of the input device may be a push button, a foot pedal, a touch-activated element, a key on a keyboard, a vision-based input interface, a voice-, 15 speech- or sound-activated interface arranged to respond to spoken commands, or any other element arranged to effect sending of an instruction to a controlling device when activated by the operator. The input device may be configured so that only an authorized individual is able to operate it. Generally, a passenger check-in station is enabled once an authorized individual logs into the particular check-in station with his or her credentials. The 20 input device may be automatically enabled upon login of the authorized individual. The controlling device may be any control device, such as an electronic control device, an electronic data processing device provided with suitable software instructions in order to perform the stated functions, etc. The term baggage checking may be understood so as to comprise baggage check-in, such as for example baggage check-in at an airport. The 25 baggage access gate may comprise a door or panel or other element suitable for forming a barrier, of any suitable material, and fitted with a mechanism such as sliding or pivoting, which is arranged to move from an open position permitting passage therethrough to a closed position restricting passage therethrough, and vice versa. The baggage access gate, may, for example, be a two-part gate wherein the parts slide in opposite directions to create 30 an opening, or it may be a pivoting panel or door, which pivots from a pivoting point to open or close.

The infeeding conveyor may comprise a conveyor belt or any other suitable conveyor type, such as a gravity roller conveyor, gravity skatewheel conveyor, lineshaft conveyor, chain conveyor, overhead conveyor, bucket conveyor, vertical conveyor, pneumatic conveyor, 35 belt-driven or chain-driven live-roller conveyor, flexible conveyor, plastic belt conveyor, vibrating conveyor, spiral conveyor, Auger conveyor, or wire mesh conveyor, et cetera.

In an embodiment, a sensor is a arranged to determine the weight of the piece of baggage or to determine whether the piece of baggage exceeds a weight limit. Alternatively or additionally, a sensor may be configured to detect the presence of a living being such as a human being, 5 for example, through infrared sensing or carbon dioxide sensing. Alternatively or additionally, a sensor may be configured to perform a 3-dimensional or 2-dimensional scan of the piece of baggage. This may be done in order to determine or approximate the size of the piece of baggage, to determine transportability, or to determine whether the baggage poses potential safety hazards. For example, the 3-dimensional scan may determine that 10 the baggage has loose straps that may interfere with operation of the baggage collection element, and alert the controller or personnel thereto, while blocking or disabling further transport of the piece of baggage. Alternatively the sensor may be configured to detect the location of a piece of baggage on the infeeding conveyor. All sensors are arranged to send a sensor signal to the controlling device. In an embodiment, the controlling device is 15 arranged to override an actuation instruction based on a sensor signal. For example, the controlling device may override the actuation instruction if the sensor signal indicates that the piece of baggage exceeds a weight limit.

The sensor may be an approach sensor arranged to detect approach of the piece of 20 baggage to the baggage access gate. The approach sensor signal is communicated to the controlling device. In an embodiment, the controlling device is configured to send an actuation signal to the baggage access gate based on the approach sensor signal, causing the baggage access gate to move from a closed position to an open position if the approach sensor signal indicates that the piece of baggage is approaching. The controlling device may 25 be configured to wait for an approach sensor signal indicating that the piece of baggage is at a predetermined distance from the baggage access gate in order to send a baggage access gate actuation signal for opening the baggage access gate. The controlling device may be arranged to maintain the actuation signal causing the baggage access gate to remain in the open position for as long as the piece of baggage is detected to be on the 30 infeeding conveyor. The approach sensor may comprise a detector array arranged substantially parallel to the direction of conveyance.

An approach sensor or sensor array, may detect movement of a piece of baggage along a direction of -5- conveyance and towards the baggage access gate by, for example, scanning an area by emitting signals, such as but not limited to, laser beams, along a direction of conveyance and evaluating the return signals or echoes.

5 In another embodiment, the device further comprises a passage sensor, which passage sensor is arranged to sense passage of the piece of baggage through the open baggage access gate. The passage sensor signal is sent to the controlling device, and if the signal indicates that the piece of baggage has passed through the baggage access gate, the controlling device is arranged to send an actuation signal to the baggage access gate 10 causing it to move from an open position to a closed position. Further, the controlling device may be arranged to deactivate the infeeding conveyor and baggage access gate upon detection of transfer of the piece of baggage from the infeeding conveyor to the baggage collection element. The passage sensor may comprise a detector array arranged substantially perpendicular to a direction of conveyance. The passage sensor may comprise 15 an optical detector array, a motion detector array, an ultrasonic transceiver array, a proximity sensor array, a laser scanner, a reflector array, or other type of sensor or sensor array, or combination thereof, which extends along a direction substantially perpendicular to the direction of conveyance and which is suitable for detecting passage of a piece of baggage through the baggage access gate area. A passage sensor or sensor array, may detect 20 passage of a piece of baggage through the baggage access gate area by, for example, scanning an area by emitting signals, such as but not limited to, laser beams, and evaluating the return signals or echoes.

In one embodiment, the device comprises both an approach and a passage sensor. The 25 controlling device is arranged to receive both the approach and the passage sensor signals and to control actuation of the infeeding conveyor and the baggage access gate based on the content of both sensor signals.

In an alternative embodiment, the device may further comprise a sensor for detecting an 30 illegal substance or unauthorized content, wherein the controlling device is arranged to override the instruction signal based on a received sensor signal indicating presence of an illegal substance or unauthorized content in the piece of baggage.

In another embodiment, the controlling device is arranged to send, after a specific time 35 period has lapsed after receiving the instruction signal, deactivation signals to the baggage access gate and to the infeeding conveyor, causing the infeeding conveyor to stop running and the baggage access gate to move from an open position to a closed position.

-6-

The baggage checking device may be arranged to hold the piece of baggage on the infeeding conveyor until it receives a signal of an available slot in the baggage collection element. For example, the controlling device may be arranged to receive a direct input or signal from the baggage collection element indicating availability of a window or windows for 5 transfer of the piece or pieces of baggage. The baggage collection element signal or input may give indication as to the timing and number of the window or windows. With this information the controlling device coordinates the actuation signal to actuate the infeeding conveyor and baggage access gate accordingly.
