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 |
