Description

Baggage size measurement and automatic handling system {BAGGAGE SIZE MEASUREMENT AND AUTOMATIC HANDLING SYSTEM}

The present invention relates to a luggage size measurement and automatic handling system, and more particularly, by measuring the size of luggage using a plurality of sensors, and automatically transporting the luggage after the size measurement has been completed, the number of people and time required for luggage handling can be reduced. It relates to a new structure of luggage size measurement and automatic handling system configured to be shortened.

Existing Baggage Handling System (BHS) allows passengers departing, arriving, or transferring at an airport to quickly and accurately classify and transport baggage that they are not carrying on board, but checked into the aircraft on which the corresponding passenger is on board. It is a system that provides services.

In such a luggage handling system, when luggage is placed on a check-in counter by a passenger, the luggage is weighed and departed, the luggage is transferred to a conveyor, and a security check is performed on the luggage transferred to the collection conveyor.

Then, the baggage handling system loads the baggage that has passed the search into a tray and transfers it to the take-off site of the aircraft on which the passenger is boarding.

Normally, baggage consignment procedures are checked by a dedicated staff after moving to a designated area to determine whether to carry on board.The number of consignment gates is extremely insufficient compared to the number of overseas travelers, which increases the number of overseas travelers every year. In particular, the processing speed was slow due to the dependence on the dedicated staff, and the burden of additional charges due to inspection errors was operated as an irrational system that was added to the consumer's share.

Accordingly, in recent years, automatic baggage handling systems are being introduced for each airport, which quickly and accurately classifies baggage checked by departure, arrival, and transit passengers using the airport, without carrying them on board, into the aircraft on which the passengers boarded in the airport terminal. This is a system that provides a transport service, but even this is manually operated by the front-end staff, so a lot of time is wasted for luggage consignment.

Therefore, there is a limit to securing the increasing demand for passengers and efficiency compared to investment by simply expanding airport facilities, and thus, a highly efficient unmanned automation system is required.

In recent years, self-service is gradually expanding to reduce the waiting time when handling luggage.In case of overseas airports, the use of the self-check-in system is constantly increasing, but in case of domestic airports, the automatic luggage consignment processing system ( Due to the lack of connection of Self Bag Drop), the utilization rate is lower than that of other advanced overseas airports.

Accordingly, in Publication No. 10-2013-0123385 disclosed in the prior art, a container for forming a template for receiving the luggage while limiting the size of the luggage to be delivered within a predetermined limit, the container includes a receiving plate And a movable bogie supporting the vertical conveyor belt, two side portions integral with the chassis of the device, and a front band that is also fixed to the chassis, and luggage is disposed on the receiving plate, and the conveyor belt The luggage is leaned, and the movable cart is rotated and raised by a tilting mechanism by a single motor to tilt the luggage from a substantially vertical initial arrangement position to a horizontal transfer position toward the collecting conveyor, and close the container. Thus, a technology consisting of a closing device that isolates luggage during rotation of the movable cart has been previously disclosed.

However, the prior art is intended to provide an automated self-service luggage consignment device used in airports, but after the luggage is delivered on a conveyor, a dedicated staff must separately perform an inspection procedure including luggage size measurement, thus reducing the senior procedure at all. This was not helpful, and as a result of the delay in check-in time for passengers, the time for luggage to arrive at the take-off point of the aircraft was delayed, and this resulted in a deterioration in airport capabilities, such as delays until the departure time of the aircraft.

Therefore, there is a need for a new method to solve this problem.

Subsequently, when the rotation speed comparison result in the first step (S1) does not match the preset rotation speed, the control unit 200 goes through a process of resetting the rotation speed of the driving unit 110, and returns the sensor module to its original position. After that, the step (S1) is performed again, and when the rotational speed of the driving unit 110 matches a preset rotational speed, the driving unit 110 is turned ON and a second step (S2) of transmitting a sensor NO operation signal is performed.

After the second step (S2), the number of rotations of the driving unit 110 is counted from the start point to the end point at which the luggage C is detected while the X-axis, Y-axis, and Z-axis sensors 101, 102, and 103 are moving. Thus, a third step (S3) of detecting the length, width, and height size of the luggage C is performed.

Finally, after the third step (S3), the detected values for the length, width, and height of the luggage (C) are compared with the allowable size values of the luggage (C) set in the control unit 200, and if they fall within the range, the luggage (C) is ) If the carry-in is approved, and if the size exceeds the allowable size, the fourth step (S4) of rejecting the carry-in of the baggage (C) is carried out automatically, from the measurement of the size of the baggage to the consignment procedure for determining whether to carry in .

As described above, the luggage size measurement and automatic handling system according to the present invention has the advantage of reducing operating costs since it is possible for passengers using the airport to directly check in luggage without the assistance of airport staff.
