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.

Conveyor belt edge module

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.

Positive-drive spiral conveyor

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.

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.

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.

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.

A modular conveyor belt constructed of a series of hingedly interconnected belt modules, one or more modules comprises a base conveyor belt module and an insert for integrating a side wall and drive structure. The insert is received in a socket of an associated module. The insert comprising a plug portion received in the socket, a planar portion extending up from the plug portion to form a side guard above the top surface and drive structure for engaging a drive.

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.
