Abstract: A tracking apparatus and method for urging a mistracking conveyor belt back towards a correct travel path are provided. The apparatus and method both utilize downstream shifting of an end portion of an idler roller due to mistracking of the conveyor belt for directing or steering the belt back toward its correct travel path and a reaction force from the belt due to the steering thereof for energizing a tilting action of the idler roller to raise the downstream end portion thereof. In this manner, the tilting of the idler roller is not mechanically coupled to the downstream shifting of the roller end portion allowing the belt tracking apparatus herein to be bi-directional for use with conveyor belts that may be run in opposite travel directions.

Abstract: A conveyor belt tracking apparatus is provided for correcting the travel path of a laterally mistracking conveyor belt. In one form, an elongate tracking roller is rotatably mounted at end portions thereof to a pivotal support frame and extends across and below the belt. The pivotal support frame is mounted to a downstream pivot member so that belt mistracking toward one end portion of the tracking roller causes the one end portion to shift downstream and laterally outwardly to urge the belt toward the correct travel path. In one approach a downstream pivot connection between the pivot member and pivotal support frame is inclined upstream so that the end portion also shifts upwardly as it shifts downstream to urge the mistracking belt edge toward the correct travel path.

Abstract: A removable cartridge cleaner assembly is provided that allows for faster and easier removal of the belt cleaner blades out from under a conveyor belt. In one aspect the assembly includes a biasing surface of one of an elongate support assembly and a channel member configured to be engaged by a securing member and urge distal ends of legs of the channel member into tight engagement with the elongate support assembly and minimize debris accumulation therebetween. In another aspect, the elongate base member and rail member each include lateral portions configured to slidably engage corresponding wedge portions to urge the rail member toward the base member. A method of installing a belt cleaner assembly is also provided which includes camming a rail member downwardly toward the support member upper surface.

Abstract: Spring tensioner devices are provided for biasing scraper blades toward a conveyor belt. The spring tensioner devices generally are constructed to be easily reconfigurable between a push-up and pull-up configuration while minimizing their space requirements.

Abstract: Compact spring tensioner devices are provided for biasing scraper blades toward a conveyor belt. The spring tensioner devices generally are constructed to have a reduced operational envelope and be reconfigurable for providing a selected one of opposite rotary bias forces.

Abstract: A removable cartridge cleaner assembly is provided that has an insertion device for ease in installing an elongate cartridge assembly carrying belt cleaner assemblies onto an elongate support extending across a conveyor belt in an operative position thereon. In one form, an elongate lever handle pivotally connected to the elongate cartridge assembly can be used to generate a leveraged insertion force, preferably by an operator that does not need to reach into the operating envelope of the conveyor system, e.g, beyond tensioning mechanisms or under the belt. The handle and the cartridge assembly can have an over center locking mechanism therebetween for providing the operator tactile feedback as to when pivoting of the lever handle has caused the cartridge assembly to be shifted to its operative position on the support.

Abstract: A belt scraper assembly having a blade holder and a scraper blade disposed therein, wherein a stiffener extending in a longitudinal direction with respect to the belt is provided in the blade body to resist bending of the blade. A scraper blade having a body with a rigid plate member connected thereto and a stiffener disposed in the body of resilient material above a base portion and below a tip portion of the plate member and extending generally transversely with respect to the length of the scraper body.

Abstract: Impact bed assemblies are provided, both static and dynamic, for absorbing impact forces taken by conveyor belts. The static and dynamic bed assemblies generally are constructed to optimize their impact absorption capacities while minimizing their space requirements under the belt.
