Abstract: A conveying system may include a frame that supports a plurality of rollers which carry articles thereon. At least one of the rollers may be a motorized roller with first and second motors adapted to rotate an outer cylindrical shell of the motorized roller. A controller external to the motorized roller may send speed control commands to the motorized roller to control both the first and second motors in a manner that increases torque of the motorized roller. The motors may be controlled in four quadrant mode, or two quadrant mode, or a combination thereof. The motorized roller may be used in a right angle transfer mechanism, or in other components of a conveying system.

Abstract: An article singulating conveyor assembly and method of singulating articles includes providing a conveying surface defining a plurality of tandem zones. The conveying surface travels in a longitudinal direction. Each of the zones includes a pair of laterally spaced side frame members and a plurality of generally parallel elongated driven rollers that are supported at the side frame members. The driven rollers are adapted to provide lateral variation in the longitudinal speed of the conveying surface. Each of the zones includes at least one drive motor that is adapted to drive the driven rollers in that zone. At least one article sensor is provided that is adapted to sensing articles in the zones. The driven rollers may be divided into a plurality of segmented rollers that are separately rotatable with a separate drive motor to drive corresponding segments for a zone. The drive motors for adjacent zones may be activated in a manner that creates a longitudinal gap between longitudinally adjacent articles.

Abstract: An encoder is provided for a conveyor having a belt, a plurality of rollers supporting the belt and a motor for driving one of the rollers. The encoder includes a hall effect cartridge having at least one hall effect sensor. The hall effect cartridge is adapted to be mounted inside of one of the rollers supporting the conveyor. The encoder also includes a magnetic ring adapted to be mounted inside the roller and rotate with the roller, wherein the ball effect sensor monitors the rotation of the magnetic ring and generates a signal in the form of pulse data based on the rotation of the roller.

Abstract: An article-conveying system and method of conveying articles includes providing a conveying surface and conveying articles with the conveying surface. The conveying surface defines a series of tandem zones, each of the zones including an article sensor and an actuator. Articles are sensed with the article sensor in the respective zone and the portion of the conveying surface at that zone is driven when the corresponding actuator is operated. Inputs are received from the article sensors at the zones and the actuators for the zones are controlled as a function of the inputs. This includes defining objects, each of the objects corresponding to one of said zones. Virtual signals are enabled between the objects. The virtual signals relate to movement of articles along the conveying surface.
