Abstract: 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.

Abstract: A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates that include openings for airflow and inner side plates that are solid to block airflow. The openings may include valves for selectively opening and closing the openings. A locking mechanism may lock two tiers together. A hold down may apply pressure to prevent destacking of the belt, or a guide may be disposed with the helical stack for preventing destacking.

Abstract: A rotatable retainer for hinge rods in modular conveyor belts. The rod retainer includes a plug that is rotatably received in a socket in the edge portion of a conveyor belt module. An aperture through the plug is adjustable between a first locked and operational position guiding a hinge rod obliquely into a hinge-joint passageway between adjacent rows of belt modules and an unlocked second position guiding the hinge rod straight into the passageway. A sideguard, such as for a stacker belt, can optionally be formed with the plug.

Abstract: A slat conveyor belt includes connected drive modules that can be easily disassembled and assembled. Each drive module comprises a slat portion connected to a drive portion forming a drive chain. A conveyor frame for the conveyor belt includes a dust cover for the drive chain and a separator for selectively separating a slat portion from an associated drive portion. A magazine automatically removes and stores separated slats.

Abstract: A conveyor belt and belt modules with plug-in accessories, such as sideguards. The accessories have plugs that plug into sockets in the belt or individual belt modules. Lugs and mounting slots and tabs and detents on the plugs and sockets help guide, register, and lock the accessories in place. The plugs and sockets allow the accessories to be locked and unlocked by twisting the plugs in the sockets.
