The invention relates to a spiral conveyor construction comprising an endless conveyor belt assembled from a plurality of substantially identical modular belt links, where the endless conveyor belt is guided on a conveying path, where at least a part of the conveying path is surrounding a drive tower, where the drive tower can rotate around a vertical axis, such that the drive tower engages a side surface of the endless conveyor belt thereby propelling the endless conveyor along the conveying path characterized in that spaced along the periphery of the drive tower are arranged vertical engagement members, where at least some of these engagement members has a vertically arranged rib projecting radially away from the drive tower, and where on a lower section of the drive tower adjacent at least some of the engagement members with projecting ribs, blocks are provided, said blocks near the bottom of the drive tower radially project further from the drive tower that the engagement members, and where the blocks are provided with a radially extending secondary rib which secondary ribs extend from the block and increases their extend upwards from zero extend to an extend corresponding to the radially extend of the rib on the adjacent engagement member near the upper end of the block, and where the secondary ribs and/or the ribs on the engagement members engages and propels the endless conveyor belt along the conveying path.

A sortation system uses short conveyors or transporter units on a lift to move products or packages to totes in a storage rack. The lift may be a carousel. Automated components remove the totes from the rack and place them on outfeed conveyors. The system to remove the totes can include a transfer vehicle. The sortation system may be modular.

A spiral conveyor system including a tank for containing a liquid at a predetermined temperature therein. A conveyor conveys items through the liquid. A guiding structure is disposed in the tank for guiding the conveyor in a spiral-type fashion. The spiral conveyor system further comprises means for securing the items while being conveyed through the liquid.

A spiral chute assembly for moving packages from an upper level to a lower level of sort facility includes a first slide inlet and an opposing second slide inlet opposite the first slide inlet. The first slide has an outlet that is above the second slide outlet in the spiral chute. The front walls of the first and second slides are angled in the direction of the approaching package to facilitate receiving the package while moving.

The present invention relates to a flexible conveyor belt assembly (100) with a chain traction system for moving products/raw materials in bulk, which comprises a support structure extending in a straight or curved manner (105), to which are fixed the rails (102), the toothed actuating wheel (103) and the toothed return wheel (106), which additionally comprises deflection wheels (109), a flexible conveyor belt (101), with a pleated profile, produced with metallic inserts (108), a chain (107) and pulleys (104) that move along the structure, in which traction is exerted on the chain (107).

A longitudinally curved support rail (56) for supporting and moving a drive chain assembly (52) at the base of a spiral conveyor belt (34) to drive the bottom tier (30) of the spiral conveyor belt while being supported by the support rail. The support rail including an upright web section (80) and a support flange (78) cantilevered outwardly from the web section to provide a platform or shelf to support a chain drive assembly (52), thereon during travel of the chain drive assembly along the support rail.

A spiral conveyor 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.
