Baggage Tray System

ApplicationThe Daifuku Baggage Tray System (BTS) is designed to handle bags in their own individual tray throughout their entire journey through the Baggage Handling System. The trays are each equipped with RFID tags which carry a unique identity which allows each tray, and therefore the bag is contains, to be positively tracked through the system. Bags loaded into trays enjoy the physical protection of the tray as well jams of bags being virtually eliminated. The trays themselves are designed to carry bags through security screening machines thereby allowing the bag to remain in the tray for its whole journey through the handling system to its make up position. Standardised trays also provide the ideal unit load basis to permit use of a wide range of storage technologies most notably advanced crane systems.

The BTS consists of modules that allow an entire baggage handling system to be built that typically mirrors and builds on the type of module often seen in conventional conveyor based systems. The system has the capability to convey bags at up to 10m/s to ensure longer journey distances, such as transfers between terminals, are completed as quickly as possible.

BTS ComponentsTrayThe tray is manufactured from a composite material designed to allow security screening of the bag whilst on the tray. It carries an RFID tag for positive tray tracking and forms the basis for handling the bag throughout the system. There are also 2 Out Of Gauge Tray sizes.

Bag SizesThe range of bag sizes that can be handled in the standard and OOG1 and OOG2 trays is shown below. As bags are conveyed through the system in trays there is an inherent ability to handle bags with straps and stability issues which cannot normally be accommodated on conventional conveyor systems.

Curve ConveyorThe curve conveyor allows the BTS system to navigate through building spaces using proven driven roller technology.

Merge/DivergeThe merge and diverge units provide the main routing element with the system allowing flows to be combined and divided according to the flow requirements. It is primarily this unit which dictates the throughput achievable with the system and its class leading 2,700 tray/hour rate allows it to meet the demands of the most rigorous systems.

Straight ConveyorThe straight conveyor is the basic conveyor element within the system. The twin strand belt technology provides cost effective and efficient conveying of the standardised tray design.

Vertical Sorting UnitThe vertical sorting unit provides the same function as its counterpart in conventional systems, it allows a tray flow to be divided into 2 vertically separated streams based on individual tray selection or route selection. Its gentle action and space saving design maximises the system design potential.

Stacker/DestackerThe tray stacker

Right Angle TransferThe right angle transfer unit allows trays to be selected from the main line and removed at right angles onto a spur. This type of transfer has many applications in the BHS system but particularly suits the interface with cranes for advanced bag storage functions.

Inclined ConveyorThe inclined variant of the straight conveyor allows the BTS system to navigate through the inevitable height changes that will be required in a typical Baggage Handling system.

BaggageTray System

Tray LoaderThe tray loader is the primary means of placing bags into trays for their journey through the system. A top loading approach is selected for its reliable operation and gentle bag handling. Bags arrive at the loading station loose on conveyor and are dynamically inducted into trays which pass underneath the loading conveyor.

Static DischargeThe static discharge is the first of the two means of discharging bags from trays at the end of their journey through the BHS, typically at the make up position. This variant offers lower throughput by stopping the tray before tilting it to discharge the bag to a transition chute back to a conventional conveyor or other chute arrangement.

Dynamic DischargeThe dynamic discharge is the high performance form of discharge it achieves its performance by tilting the tray to discharge the bag whilst it is still moving thereby reducing the cycle time and enhancing the performance.
