Track frame assembly in conveyor system

Abstract

A track frame assembly is provided which includes a frame member formed from an elongated metallic channel, a pair of elongated synthetic resin-made track rail members each fixed in place on a predetermined surface of the frame member, and a plurality of rail fixtures with which the pair of track rail members can removably be fixed to the frame member. Each of the track rail members includes a retaining projection having a retaining recess formed therein, the pair of track rail members is disposed for the retaining recesses to be opposite to each other and each chain element of the conveyor chain has a pair of engaging projections which are formed to slide in contact in the respective retaining recesses in the track rail members in pair, thus the conveyor chain being smoothly movable without disengagement from the pair of track rail member. Thus, the track frame assembly can be formed from a reduced number of parts and designed lightweight because of its structural simplicity, is easy to assemble, can retain ample strength and precision, is easy to handle and maintain and inexpensive.
