Abstract: A belt tension-reducing device is provided, which includes a support member; a pliable central wheel assembly configured to engage a both downwardly and upwardly moving portions of the conveyor belt; first and second outboard roller assemblies positioned to engage the downwardly and upwardly moving portions, respectively. A second effective rolling radius of the pliable central wheel assembly at a contact point with the upwardly moving portion of the conveyor belt can be greater than a first effective rolling radius of the pliable central wheel assembly at a contact point with the downwardly moving portion of the conveyor belt to reduce stresses on the belt in a vertical shaft. The belt tension-reducing devices can be arranged in a stacked configuration within the vertical shaft.

Abstract: A method for controlling tension in a belt of a conveyor system. The method involves: driving the belt along a path from an intake region to a discharge region using an intake motor adjacent the intake region and a discharge motor adjacent the discharge region; measuring a tension in the belt using an intake belt sensor that moves with the belt proximate the intake region to generate an intake belt signal; measuring a tension in the belt using a discharge belt sensor that moves with the belt proximate the discharge region to generate a discharge belt signal; monitoring the intake and discharge belt signals; and adjusting at least one of the intake motor and the discharge motor based on the intake and discharge belt signals to maintain the tensions in the belt within a pre-defined range.

Abstract: A self-aligning belt pulley, in various embodiments, includes a cylindrical roller having one or more concave portions formed in a circumferential rolling surface. In some embodiments, one or more raised peaks extend circumferentially along, and radially outwardly from, the circumferential roller surface. In various embodiments, a cylindrical roller couples with a pivoting mechanism having an elongated member that is offset and parallel to the circumferential rolling surface. The elongated member has a centrally located connection point that permits a pivoting bracket to be attached to it, thereby creating a pivot point that is anchored at an opposite end portion and automatically adjusts a position of the cylindrical roller. The pivoting mechanism may also function as a tensioning device.

Abstract: According to one embodiment, a diagnostic system includes a conveyor device first and second sensors and a diagnostic device. The conveyor device includes an endless chain having a plurality of rollers coupled at regular pitches and each fit into a bush, to circularly move between a first sprocket and a second sprocket. The first and second sensors diagonally are disposed apart from each other on a moving path of the chain, irrespective of an operating direction of the conveyor device, to detect a passage of each of the rollers of the chain. The diagnostic device measures an amount of elongation of the chain based on a first detection signal output from the first sensor and a second detection signal output from the second sensor according to movement of the chain during operation of the conveyor device.

Abstract: A conveyor construction for a continuous belt conveyor. The conveyor includes a conveyor frame assembly constructed from a plurality of separate extruded and joined frame sections. The frame assembly can include a pair of side frame extrusions joined to a center frame extrusion by a pair of attachment rails. The conveyor construction further includes a series of spindle mounting assemblies that support a tensioning spindle on opposite ends of the conveyor frame. Each of the spindle mounting assemblies includes a gear rack and a pinion head that is rotatable to move the gear racks. The gear racks contact one of a pair of head plates that support the tensioning spindle relative to the frame.

Abstract: A conveyor system that includes a sprocket, a conveyor element, a sensor, a tensioning system, and an electronic processor. The conveyor element is coupled to the sprocket to move around the sprocket. The sensor is positioned adjacent to the sprocket and configured to generate an output signal indicative of a detection of the conveyor element. The electronic processor is coupled to the sensor and to the tensioning system. The electronic processor is configured to receive the output signal from the sensor, estimate a trajectory of the conveyor element based on the output signal, determine a value for slack distance based on the estimated trajectory of the conveyor element, and control the tensioning system based on the value for slack distance.
