A CONVEYOR UNIT FOR USE IN A CLOSED LOOP CONVEYOR SYSTEM AND A CONVEYOR SYSTEM

摘要

A conveyor unit for use in a closed loop conveyor system for transportation and/or sorting of goods comprises a frame structure (2, 3) having at least two pairs of caster wheels (4). Each pair of wheels is mounted on a wheel mounting member (5), at least one of which is connected to another part of the frame structure pivotally around a substantially vertical axis (6), so as to allow mutual displacement of two or more sub-trolleys or sub-wagons comprised in each conveyor unit. One or more receptacles comprising tiltable trays or cross-belts for carrying articles may be comprised in the conveyor unit. The conveyor unit may have a relatively long receptacle and/or relatively long common goods supporting surfaces constituted by a plurality of receptacles. Improved track-holding qualities and high capacity and/or flexibility may be achieved.
