Abstract: A conveyor system includes a conveyor belt having a plurality of article-diverting conveyor belt rollers. An underlying drive roller assembly includes a plurality of pivotable rollers carriers, each having a freely rotatable drive roller that contacts the conveyor belt rollers from below. An actuator engages an orientation device to pivot the carriers and change the orientation of the drive rollers. The drive rollers may also move into and out of engagement with the conveyor belt rollers as their orientation changes. The orientation device is sandwiched between three-dimensional support plates to adjust the orientation of the drive rollers relative to the belt rollers. A top support plate includes corrugated vertical walls forming wearstrip holders. The orientation device may raise or lower the drive rollers during pivoting of the roller carriers. The drive roller assembly may be a modular assembly that can be customized for varying sizes, shapes and configurations.

Abstract: A system and method for detecting disengagement of a modular articulating conveyor belt from a toothed pulley with a laser beam. A laser transmitter and a laser detector are positioned at opposite sides of the modular conveyor belt wrapped around a toothed pulley. The laser beam is directed from the laser transmitter to the laser detector along a line that is intermittently intersected by radially outer structure on the belt as it advances fully engaged with the pulley. When the belt stretches with wear or when debris is trapped between the belt and the pulley, the belt starts to ride higher on the pulley in position to block the laser beam for longer time periods indicating disengagement of the belt from the pulley.

Abstract: A tracking system using a rangefinder, such as a Lidar sensor, to track objects conveyed on a belt conveyor. The rangefinder produces depth frames in a field of view encompassing a portion of a conveyor. The depth frames comprise an array of pixels whose values represent distances from the rangefinder to reflective surfaces in the field of view. The rectangular reflection surfaces of objects are identified and their dimensions and centroids are calculated so that the objects can be tracked from frame to frame. An object's trajectory angle Θi is computed and stored in a tracking buffer array. Conventional smoothing techniques can be used to convert the piecewise linear trajectory (30) into a smooth curved trajectory. If an object is being conveyed on a conveyor belt without slipping on the belt's surface, its component of velocity vx in the x direction can be used as an estimate of the speed of the conveyor belt. The orientation of the object can be tracked from frame to frame to reveal whether the conveyor belt is changing the object's orientation relative to the conveying direction.

Abstract: Apparatus and method for activating conveyor belt roller assemblies by lowering and extending wearstrips to selectively lower the conveyor belt to place the conveyor belt roller assemblies into contact with actuating rollers. A wearstrip module housing the wearstrips includes an upper support upon which the wearstrips are mounted that is longitudinally and vertically movable relative to a lower support fixed relative to the actuating rollers. Mounting brackets rotatably mount the lower support and actuating rollers in a fixed position and orientation.
