  • Patent number: 4179025
    Abstract: A conveyor system consists of an endless loop of pallet assemblies linked together and mounted on a number of modules positioned end-to-end. One, at least, of these modules is a drive module but the remainder are non-powered. The drive module includes a pair of chains having links whose pitch is a sub-multiple of the pitch of the teeth on driving wheels. Teeth are provided on the pallet assemblies to engage the chains. A lateral guide roller has an axle which serves also as part of an articulated joint between successive pallet assemblies. The pallet assemblies can each be formed of a rigid portion linked to a flexible portion. Each pallet assembly has a pair of guide rollers to engage guide sections for vertical positioning. A single chain drive and pins on the pallet assemblies to engage the chain are alternatives.
