A technique is provided for diagnosing deficiencies in a material handling system having a track and a material support member adapted to travel on the track. A diagnostic device travels with the material support member and includes one or more sensors that measure one or more parameters of the material support member. Such parameters may include an amount of force exerted laterally against one or more restraining members or the accelerations of the material support member. The material handling system may include a plurality of slats connected in an endless web that defines a conveying surface upon which articles are transported.

A method of reducing drag on the web of a positive displacement sorter is used with a web made up of a plurality of parallel slats interconnected at their opposite ends with chain assemblies in an endless loop. A plurality of pusher shoes each travel along at least one of said slats. The sorter further includes a driven sprocket assembly and a non-driven sprocket assembly. Each of the sprocket assemblies includes at least two sprockets on a shaft, each for engaging one of the chain assemblies. The sprocket assemblies support the chain assemblies at opposite ends of the web. The method includes auditing the sorter including determining if the slats are skewed with respect to the direction of travel of the web. If it is determined that the slats are skewed, then the chain assemblies and the non-driven sprocket assembly are modified. The chain assemblies are modified by adding side thrust wheels on opposite sides of the web. The non-driven sprocket is modified by locking the sprockets to the shaft such that the sprockets rotate together.

A conveyor system aligner, method of aligning and continuous aligning belt includes providing a belt support assembly having a generally vertical support surface and a channel defined in the support surface. A belt drive propels the aligning belt along the support surface and items, such as cartons, are conveyed past the aligning belt. A continuous aligning belt is provided that has a contact portion and a guide member. The contact portion has a contact surface and a glide surface. The glide surface is configured to travel along the support surface. The guide member is adapted to be captured by the channel and travels in the channel to support the aligning belt.

A paddle diverter assembly according to the present invention includes an arm and an actuator for actuating the arm to move toward a diverting position. The actuator is adapted to permit the arm to move away from the diverting position upon impact with the object to be diverted and then to return to the diverting position to thereby absorb at least some of the impact between the arm and an object being diverted.

A conveyor roller includes at least one axle cartridge and is mounted at opposite sidewalls of a conveyor. The axle cartridge includes a bearing assembly at an outer end and an inner support at an inner end. The bearing assembly provides rotational support of a roller portion about the axle portion, while the inner support is spaced from an inner end of the axle portion during normal use of the roller. The inner support may provide contact support at the inner axle portion in response to loading induced deflection of the roller, whereby the inner support limits flexing or bending of the roller portion and may limit binding of the bearing assembly during such loading conditions. The axle portion may include one or more guide members arranged along a generally tapered or conical-shaped axle end for guiding the axle portion into a correspondingly formed opening in the conveyor sidewall.
