    Abstract: A spiral conveyor and a method for taking up slack in a modular conveyor belt traveling a helical path. The spiral conveyor includes a rotating cylindrical drive drum with parallel drive members extending from the bottom to the top of the drum on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the drum for engaging the inside edges of the belt. A motor-driven take-up shaft and shaft-mounted sprocket set takes up slack in the belt after its release from the drum. To control tension at the discharge of the belt from the drive drum, the take-up motor is normally operated in a closed-loop control mode, but switches to an open-loop constant-speed control mode when the take-up motor stalls.

    Abstract: A spiral conveyor for positively driving a conveyor belt (20) along a helical path. The spiral conveyor includes a rotating cylindrical tower (10) with parallel drive members (14) extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge (28) 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. In another version, a conveyor belt has teeth (62) with guide surfaces (78, 79 ) at the inside edge of the belt. The teeth guide the drive members between belt rows into driving engagement with drive faces at the inside edge of the belt.

    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 (50) that include openings for airflow and inner side plates (80) 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 magnetic conveyor belt module integrates a magnetic element into the body of the module to attract conveyed articles to the body. The magnetic conveyor belt module includes a recess for seating a magnetic element and a retention element for retaining the magnetic element within the recess. A cover encapsulates the magnetic element within the body of the module. A non-magnetic conveyor belt module is connected to the magnetic conveyor belt module to form a conveyor belt. The non-magnetic conveyor belt module has an upper surface that is flush with or above the upper surface of the magnetic conveyor belt module.
