ABSTRACT:
An improved spiral conveyor comprising a rigid integral central tubular core member which is arranged vertically dependent upon the desired height of the conveyor system. A continuous conveyor chain is moved over a pair of continuous spaced tracks which are mounted in a generally spiral path about the central member. The tracks are constructed and arranged to include flat surfaces disposed for minimizing frictional contact with the conveyor chain whereby the capstan affect is reduced. The chain is driven at its infeed and outfeed ends by an electric motor disposed at one of these locations and is reversible depending upon the desired direction of flow. The chain returns upon itself. The infeed and outfeed ends of the conveyor chain are arranged in tangential relationship with respect to the adjoining portion thereof to facilitate side transfer, if desired, of the conveyed product. The tracks are provided with a continuous channel for further reducing frictional contact with the adjacent overlying conveyor chain as well as providing a lubrication reservoir for receipt of grease dispersed from grease injectors disposed along the path.
