COLUMN DRIVE FOR SPIRAL CONVEYORS

摘要

A center column drive for a spiral conveyor is used to rotate a drive tower to move a conveyor belt in a helical pattern. The drive tower is driven by the center column drive to cause rotation about a vertical axis. The center column drive includes a base having a platform and a plurality of support legs that support the platform. The center column drive also includes a slew ring that is secured to the platform at one end and to a center column of the drive tower and a second end. Rotation of an electric gear motor causes rotation of a portion of the slew ring, which, in turn, rotates the drive tower.

主权项

1. A center column drive spiral conveyor system comprising:
a rotating cylindrical drive tower having a lower end and a spaced apart upper end and having a central column, the drive tower adapted to rotate about a vertical axis of rotation; a plurality of parallel drive members coupled to the drive tower, the drive members extending in length from the lower end to the upper end of the drive tower; a conveyor belt extending helically around the drive tower, the drive members adapted to engage the conveyor belt; a center column drive that is adapted to rotate the center column, the center column drive including a drive ring having an upper ring coupled to the drive column and a lower ring, the upper ring adapted having a plurality of gear teeth and configured to rotate with respect to the lower ring; and a drive motor that is adapted to rotate the upper ring to cause the rotation of the drive tower and movement of the conveyor belt.
