ABSTRACT:
There is provided a conveyor system for conveying items and including a carrier for such items to be moved between at least two spaced-apart stations and a first guide track extending between the spaced apart stations. A flexible drive tape having a leading edge and a trailing edge is reciprocably mounted within the first guide track for moving the carrier between the spaced-apart stations, wherein the flexible drive tape is attached to the carrier adjacent the leading edge by a plurality of connectors. At least one of the connectors allows controlled relative movement between the tape and the carrier. A toothed cog wheel is preferably provided around a substantial portion of the periphery of which the drive tape is wound within a cog surround which at least partly encloses the cog wheel and the wound drive tape. The surround further includes a pair of tape peeler tips oppositely disposed adjacent the cog wheel to peel the tape away from the cog wheel as the wheel is rotated in use. The carrier is supported adjacent the first guide track as it is conveyed by the drive tape between spaced apart stations, and a second guide track is provided for receiving the trailing edge of the drive tape. In a preferred embodiment, docking members provide additional support for said carrier at the stations.
