Dubois Ltd of Corby is part of the AGI Media Packaging group and manufactures cases for video cassettes, CDs and DVD disks. Egemin creative technology was used within their warehouse, using four battery powered Egvs to handle the storage of 7,000 pallets of finished goods, which is managed by Egemins Ewms warehouse management software.
The vehicle movement is supervised and controlled by an Etricc computer system, which controls the assignment of orders to the vehicles and traffic control by radio data communication.
The Egvs follow pre-defined guidepaths as they transport pallets from production lines input locations to the warehouse. Each Egv is equipped with an onboard microprocessor which controls the vehicle and determines its location by taking input from encoders, steer potentiomenters and antennae.
When the pallets are ready to be despatched, the warehouse management software sends orders to the Egv system to bring pallets from the warehouse to the expedition lanes. To optimise the capacity of the system, the Egvs transport two pallets at once. The pallet fork lift are specially designed to handle two pallets, one behind the other. When the 660 Amp Hour vehicle battery is low or there are no orders to be executed, the Egv will move to the battery station to be automatically recharged (opportunity charging). Every Egv has a spare battery to guarantee 24/7 working time of the system.
