Abstract: A spiral conveyor having a self-stacking conveyor belt positively driven on a helical path up or down a drive drum. Stacker supports at opposite sides of the belt support the tiers above. Locking structure on the outer stacker supports interlock consecutive tiers. Drive members on the drive drum have a belt entrance segment and a positive-drive segment. The positive-drive segment has ridges that engage the inner side of the belt without slip. The entrance segment provides a smooth reduction in drum diameter without drive ridges to multiple belt tiers entering the helical path.

Abstract: A spiral conveyor and methods for positively driving a conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower.

Abstract: A spiral conveyor for positively driving a hinged, modular conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the tower for engaging the inside edges of the belt. In one version, the ridges at the entrance end of the spiral are movable to provide a gradually decreasing spacing between consecutive ridges as the belt enters the spiral. In another version, alignment elements at the entrance end align belt-edge structure with the tip ends of associated ridges to help engagement. In another version, the ridges at a discharge end of the tower are retractable between an extended position driving the belt and a retracted position.
Abstract translation: 螺旋输送机，用于沿着螺旋路径正向驱动铰接的，模块化的输送带。 螺旋输送机包括旋转的圆柱形塔架，其平行驱动构件在其周边从塔的底部延伸到顶部。 每个驱动构件包括从塔的底部延伸到顶部的向外突出的脊，用于接合带的内边缘。 在一个版本中，当螺旋带进入螺旋时，螺旋入口端处的脊可移动以在连续脊之间逐渐减小间隔。 在另一个版本中，入口端处的对准元件将带边缘结构与相关脊的尖端对准以帮助接合。 在另一种形式中，塔的排出端处的脊可以在驱动带的延伸位置和缩回位置之间缩回。

Abstract: Overlapping cage-bar caps in a spiral belt conveyor. The cage bars of a spiral-conveyor cage are covered along the majority of their length by a main cage-bar cap fastened to the cage bar at the exit of the belt from the spiral. At the belt's entrance to the spiral, an entrance cage-bar cap overlaps a portion of the main cage-bar cap and the cage bar. The overlap is great enough to prevent a gap from forming along the length of the cage bar between the main cage-bar cap and the entrance cage-bar cap.
