Description

Three-dimensional storage system of transmission sorting car and realization method Technical field

The invention relates to a three-dimensional storage system, in particular, to a three-dimensional storage system of a transmission sorting vehicle and an implementation method thereof.

Background technique

In daily life, since the airport does not have large-scale luggage storage facilities for fast entry and exit, the checked-in luggage must immediately enter the departure transfer sorting area. Therefore, it is stipulated that the luggage check-in time is limited to 2 hours before the flight departure, which has many defects . For example, passengers arriving early at the airport need to wait for a long time with their luggage, which causes inconvenience to passengers; however, when checking in, passengers need to wait in long queues for check-in.

At the same time, there is no place to store some luggage at the existing airport, which forms a stack. For example, city check-in luggage is usually delivered to the airport early, and storage space for early luggage needs to be provided; when the flight is grounded due to weather or aircraft failure, It is also necessary to unload the installed baggage from the aircraft, and the unloaded baggage for multiple flights can only be temporarily stacked and stored.

In addition, because the airport occupies a large space, in order to reduce manual handling, it is necessary to use rollers and belts to drive luggage for transmission, which also has many defects. For example, the transmission of luggage requires a corresponding power system, coupled with the application of rollers and belts, resulting in high cost of the entire transmission system, and the turning radius of the belt (roller) transmission mechanism is mostly 2.2-2.55 meters, and the poor turning radius is large. The land area is large; only one piece of luggage requires the entire power system to operate, resulting in low efficiency and high cost; in addition, the entire storage structure is composed of "palletizer + rack" or "shuttle + rack" or "lift + elevator". "Shuttle + rack" structure, its structure is complex, the palletizing capacity is low, only 1200 pieces/hour; at the same time, the speed of baggage loading into the pallet is low, 1800 pieces/hour on the top, 90 pieces/hour on the side, and the pallet is changed. The speed of the baggage pallet is slow; the transfer or separation of the luggage pallet has a complicated structure and cannot cross on the same plane. The speed is low, 1800 pieces/hour, which results in low operating efficiency and high cost of the entire storage system.

In order to cope with special circumstances, the storage system also includes a process of calling out specific baggage in the orbital area 130.

1. Luggage climbs up the ascending track area 110

As shown in Figures 6 and 9, the transmission sorting vehicle enters the ascending track area 110 from the ground track. At this time, the vehicle RFID reader of the transmission sorting vehicle recognizes the information of the track node RFID tag 314 next to the ascending track area 110. By comparing the information of the RFID tag 314 of the track node with its own flight number, the transmission sorting car is then controlled to enter the flight separation track area 121 of different layers. specific:

(1) At the connection between the ground track and the first-level climbing track A1, the vehicle RFID reader/writer recognizes the information of the track node RFID tag 314. If it is the same as the flight instruction of the transmission sorting car, it will automatically control the transmission sorting car in the first Go straight at the climbing turn track A1 into the second climbing turn track C1, and then enter the storage area 120 on the first floor; if the information of the identified track node RFID tag 314 is not the same as the baggage flight number of the transmission sorting car, the sorting car is transmitted Turn at the first-level climbing track A1 to enter the second-level climbing track A2;

(2) When approaching the warehouse zone 120 on the second floor, the vehicle RFID reader/writer recognizes the information of the track node RFID tag 314. If it is the same as the flight instruction of the transmission sorting car, the transmission sorting car is automatically controlled to be on the second floor. Go straight on the climbing track A2 and enter the second climbing turn track C2, and then enter the second-level storage area 120; if the information of the identified track node RFID tag 314 is different from the baggage flight number of the transmission sorting car, the transmission sorting car is in At the second-level climbing track A2, turn to enter the third-level climbing track A3;

(3) By analogy, until the transfer sorting truck looks for the same storage area 120 as its own flight.

2. Baggage enters the flight storage track area 122 through the flight separation track area 121

As shown in Figures 8 and 10, each storage area 120 will have more than ten flight storage tracks. Therefore, after the transport sorting truck loads luggage into the entrance of the storage floor, it needs to find and identify its own baggage flight storage track.

The vehicle RFID reader recognizes the information of the track node RFID tag 314 next to the flight separation track area 121, and compares the information of the track node RFID tag 314 with its own flight number. If the information is the same, the transmission sorting vehicle automatically turns and enters the designated Flight storage track; if they are not the same, continue to execute, read the information of the next track node RFID tag 314, and finally find the same flight storage track as your own flight, and complete flight baggage sorting and storage.

3. Baggage enters the flight storage track

As shown in Figure 8 and Figure 11, the rail node RFID reader 317 next to the flight storage rail area 122 reads the information of the RFID tag of the vehicle in the sorting car, and reports to the data center 200 the code of the baggage entering the storage rail and the entry The data center 200 confirms the storage location of each piece of luggage, and the data center 200 masters the data of the baggage in and out of the warehouse track of each flight to ensure the accuracy of baggage operation.

If it is the first baggage that enters the track, the stop instruction pile 311 at the front end of the flight storage track instructs the transfer sorting car to stop, and then the transfer sorting car that enters the storage rail moves forward, and the speed control anti-collision bar touches the front The stopped sorting car will automatically brake to stop moving forward and automatically arrange in the storage track.

After the RFID reader 317 of the rail node at the front exit of the flight storage rail area 122 sends out the flight baggage out instruction in the data center 200, the stop instruction pile 311 is first closed, and the transmission and sorting truck automatically starts to move forward and passes through the front exit. When the time, the track node RFID reader 317 automatically records the outgoing baggage code and outgoing serial number, and outputs them to the data center 200, and the data center 200 confirms the information of each outgoing baggage.

4. Baggage enters and exits the warehouse and enters the track area 123

The transfer sorting car in the flight storage track area 122 receives the instruction to leave the warehouse, and the transmission sorting car enters the outgoing warehouse and enters the track area 123. Specifically, the transfer sorting car out of the flight storage track area 122 needs to be imported In the descending track, the multiple tracks are merged into one track. First, the steering instruction pile 312 at the side of the merging track is identified, and the turning is automatically controlled to enter the exit merging track.

5. Call out specific baggage in the circling track area 130

As shown in Figure 8 and Figure 12, because the passenger changes the flight or terminates the trip, he needs to retrieve his original stored luggage, or needs to retrieve the luggage of a certain passenger for safety reasons. during this process:

(1) First, determine the baggage code, transmission sorting vehicle code, and flight code that need to be called out, and the data center 200 starts to call out the transmission sorting vehicle in its baggage flight storage track.

(2) The RFID reader 317 of the orbit node in the flight storage track area 122 and the outbound track area 123 reads the information of the vehicle's RFID tag. When the code that needs to be retrieved is read, the data center 200 immediately shuts down.
