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: An edge module for a modular conveyor belt. The edge module includes a rod-retention plug that is pivotably mounted in a socket that opens onto the module's bottom. The plug has a bore that receives an axle in the socket on which the plug can be rotated. An arm attached to a main body of the plug by a living hinge allows the arm to flex from a relaxed state occluding a hinge-rod passageway at the belt's hinge joints to a flexed state allowing a hinge rod to be inserted into or removed from the passageway. Locking structure on the plug and in the socket engage to lock the plug in place. A sideguard mounted in the edge module is locked in place by locking structure in the edge module. Locking structure on both the sideguard and the plug engage to lock the sideguard and the plug in place.

Abstract: Belt modules with wear pads for constructing modular plastic conveyor belts. A conveyor belt made of the modules is supported in the carryway of a conveyor atop linear wearstrips along which the belt's wear pads slide as the belt advances.

Abstract: An omnidirectional anemometer and a method for using such an anemometer to measure the airflow along a conveying path, such as a helical path through a processing chamber. The anemometer is a low-profile, omnidirectional, three-axis anemometer with minimal airflow-occluding structure. Because of its low profile, the anemometer can fit in spiral conveyors with a short tier pitch.

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 conveyor control system detects imbalances in a multi-drive conveyor belt and institutes a corrective action to rectify the imbalances. A sensor detects imbalances by measuring gaps between consecutive conveyor modules near a drive for the conveyor belt. A controller can initiate an alarm or automatically modify one or more drives to correct a detected imbalance.

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.
