Induction Conveyor

Application

The process of inducting bags onto a tilt tray sorter is an arduous task that demands high levels of accuracy whilst performing thousands of cycles that may involve changes in loading, speed and direction. In order to survive in such a demanding environment Daifuku Logan induction conveyors are designed to meet and exceed the loading placed upon them. This approach ensures high system availability by minimising bag positioning errors and mechanical breakdown.

The Daifuku Logan induction conveyors are based on the proven Model 571 queue & Model 684 merge conveyors that have been in service in airport applications for many years. Each conveyor element in the induction line has its own drive and DCP complete with inverter for flexibility and performance. Provision can be made for ‘under scanners’ and hand safe devices within the design. The final merge conveyor is of the multi belt type and gives an injection angle of either 30° or 45° dependent upon application and sorter speed.

The induction conveyors are clad along their full length to prevent ingress of labels and other debris and to give a pleasing appearance.

Induction Conveyors are designed to operate in a stop
/ start or dynamic mode. The mode of operation is dictated by the throughput requirements.

General Description

Conveyor Construction

The Conveyor modules are constructed from fabricated, press formed, 2.5mm painted mild steel. They comprise of a formed bedplate bolted between two flanged side frames. The bedplate is reinforced by stiffeners across the width of the conveyor. The modules are mounted on purpose built rigid steel frames.

Drive Configurations

Drive is imparted to the drive pulley by an underslung geared motor, via a heavy duty timing belt (HTD). The drive components are totally enclosed within a sheet steel guard. The motor gearbox is normally supplied with an integral brake for this rapid stop/start application the brake is separately and directly excited.

Pulleys

The drive pulleys are of a fully fabricated construction for concentricity. Mounted between externally mounted bearings, which can be suitably adjusted to align the pulley and provide easy access for routine maintenance. Head and Tail pulleys and snubber Rollers with less than 45o of belt wrap are fitted with internal "sealed for life" bearings. Typical pulley diameters are:

Head & tail Pulley - 82.5mm O/D - 35mm Internal Bearing and Drive Pulley 124.5mm O/D   40mm Bearing Dia
Snubber Roller  76mm O/D     30mm Internal Bearing

Daifuku Logan Ltd, one of the World’s leading manufacturers of automated baggage handling systems, in partnership with Logan KSEC, is pleased to announce the successful delivery of its largest ever state-of-the-art BNP specification baggage handling system for the brand new T3 Terminal at Wuhan Tianhe Airport in China.

 

 The baggage system compromises of 6 check-in islands, each with 20 check-in desks, 18 arrivals carousels, 6 transfer baggage lines, 4 manual coding lines, 48 EBS lanes and 8 screening lines. The screening lines have 6 automatic MV Xray machines and 4 automatic CT Xray machines with additional explosive trace detection and level 5 baggage resolution areas.

 

 At the heart of the system lie 4 of Daifuku Logan’s leading edge tilt tray sorters consisting of 1462 trays with 30 induction points and over 400 chutes.

 

Baggage identification is realised by Radio Frequency Identification (RFID ) integrated seamlessly into all systems, this coupled with the end to end data tracking is reaching identification rates far beyond what is possible with standard optical systems. Each tilt tray sorter chute is fitted with a final RFID based bag information display system which automatically reads the bag as the bag is loaded into the unit loading device (ULD).

 

 Critical systems, such as the tilt tray sorters, utilise the latest Hot Standby PLC’s and full redundant power and network installations to ensure the highest availability possible.

Higher level systems supplied include SAC, 3D SCADA, CCTV, maintenance management and ATR management servers.

A tote return system delivers empty totes from the baggage hall back to each of the check-in desk positions.

 

Construction of the 220,000m2 Terminal started in June 2013 at an estimated cost of 40 billion yuan (£4.6 billion), and project delivery included a new runway, new control tower noted to be the tallest in Asia and a transportation hub connecting the airport to the city with intercity railway and metro line.

Starting from August 31st, all flights from T1 (international, Hong Kong, Macau and Taiwan) and T2 (domestic) were moved to Terminal 3, which is expected to accommodate 35 million passengers annually by 2020.

Daifuku Logan Ltd’s Managing Director, Ron Osborne stated:

“We are delighted with the new system, its leading edge, on time, on target delivery is a testament to the excellent working relationships and dialogue we have with the airport, the design teams for the terminal building, right down to all the sub-contracting companies since the projects conception.

We very much look forward to working closely with the airport on any of its future BHS project requirements”.
