Abstract
A product transport system which is located predominantly within a chamber 10 (for example, an industrial oven chamber) and which comprises a pair of parallel, spaced apart conveyor chains 19. The conveyor chains are arranged to convey a plurality of transversely extending product support trays 15 through the chamber 10. Pairs of transversely spaced carriers 31 are provided to carry respective ones of the trays 15. Chain sprockets 20 are located within the chamber in alignment with the respective conveyor chains and the sprockets 20 are arranged to direct the respective conveyor chains through changes in direction (including through forward-and-return horizontal passes) within the chamber 10. Rotatable guide members 28 in the form of toothed wheels are positioned laterally adjacent to but out of alignment with respective ones of the chain sprockets 20, and a subsidiary chain drive is provided for driving each guide member 28 in synchronism with an adjacent one of the chain sprockets 20. Each of the carriers 31 has a first spigot 34 that is connected to an associated one of the conveyor chains 19 and has a second (relatively shorter) spigot 38 that is positioned to engage with one o…
