Abstract: A directional discharge wing pulley having a plurality of wings that discharge material in a single direction while properly tracking the conveyor belt. The directional discharge wing pulley may include a plurality of directional discharge wings, which are generally angled in a single or primarily in single direction across the entire face of the pulley. When pulley is operated a reverse rotation direction, the conveyor belt continues to properly track and the material is discharged in the opposite direction. The wings may have bends to create flat sections, or formed in a multiple arc pattern to create smoother changes in geometry or increased wing angle near the ends of the pulley, while generally maintaining a single direction wing through the entire pulley. Strengthening rib bends may be added near the end of a straight wing to add rigidity reducing the likelihood of wing fold over. The wings may include secondary wings, for example, in a Herringbone pattern.

Abstract: A conveyor pulley design incorporates a plow design that forces tramp material away from the belt and discharges material down and away from the belt, bearings, take-up assembly, maintenance equipment and personnel. The pulley uses a modular construction that allows for optimized manufacture and inventory processes and reduces the materials cost in the pulley.

At the end of each painting cycle, clean solvent is made to flow into the solvent vessel and the cleaning cylinders and the conveyor belt of the painting machine are temporarily kept active so that they clean themselves.

Abstract: This invention relates to a seal for protecting an end of an idler roll against contaminants. The seal includes a fastener engageable with the end of the idler roll and an integral first sealing member molded onto the fastener and extending radially outward from the fastener. A second sealing member is integrated with the first sealing member. The first sealing member and the second sealing member project into frictional engagement with the end of the idler roll. When assembled with the end of the idler roll, the first sealing member and the sealing member are biased into frictional engagement with the end of the idler roll, thus protecting the end of the idler roll from contaminants in wet environments.

Abstract: An idler roller assembly for a belt conveyor includes a fixed shaft, a roller mounted for rotation about the shaft, and a housing mounted in each end of the roller for rotation therewith. The shaft has a hub portion adjacent each end which hub portion is disposed adjacent the housing. A bearing has an inner race secured to the shaft and an outer race secured to the housing. A unitary co-injected annular seal having a first labyrinth seal portion and a contact seal portion composed of a different material than the first labyrinth seal portion is provided between the bearing and hub portions. The contact seal portion is preferably resiliently deformable and is less rigid than the first labyrinth seal portion. A second labyrinth seal portion cooperates with the first labyrinth seal portion to define a labyrinth passageway which is sealed by the contact seal.

Each roller includes, at each of its ends, a metal end plate and an end bearing, received in the end plate, for rotatably supporting the roller relative to the shaft. To protect against the entry of contaminants, an end seal assembly, including an inner seal member mounted to the roller, and an outer seal member, mounted to the stationary shaft, is provided at each end of the roller. The inner and outer seal members are formed of molded plastic and co-operate with each other, and with the roller end plate, to form a labyrinth-like passageway leading from the end bearing to the exterior of the roller. The outer seal further includes a metallic nut for facilitating mounting to the stationary shaft.

Abstract: An idler roll assembly for conveyors is provided which is particularly adapted for one-shot lubrication. The assembly includes roll mounting bearings having inner races which are mounted on a tubular roll mounting shaft and inner and outer grease seals which define a bearing chamber. Lubricant is admitted to the bearing chamber from a bore in the tubular roll mounting shaft and through a radial passageway which communicates with another passageway defined by the inner bearing race and a channeled portion of the shaft. The outer grease seal is a labyrinth seal comprising a first labyrinth portion fixed with respect to the roll and a second labyrinth portion fixed with respect to the shaft. A grease release lubricant passage is defined between the second labyrinth portion and the shaft.

Abstract: A conveyor belt advances over an assembly of cylindrical idler rollers. Each idler roller includes a cylindrical body rotatable about an axially disposed tubular shaft. Air under pressure enters the proximal end of the tubular shaft and advances through the tubular shaft to be discharged through openings in the distal end of the tubular shaft. The air under pressure leaving the distal end of the tubular shaft advances through the space between the inner wall of the cylindrical body of the idler roller and the outer wall of the tubular shaft to be vented to atmosphere for reducing heat build-up in the idler roller.

Abstract: A series of flexible, substantially cylindrical tubes communicates with the hollow central bores of shafts of adjacent idler rolls to form a conduit so that lubrication introduced through a fitting at one end of the idler roll assembly can be distributed in sequence to all of the rolls. Opposite ends of each tube are secured in position by insertion into an axial passageway in the end caps secured to the ends of the shafts. In the preferred embodiment, each passageway has a tapered entrance to facilitate the insertion of a tube, and a radially inwardly extending knife edge at the inner end remote from the entrance. The diameter of the passageway along its axial extent is slightly larger than the external diameter of the tube, while the diameter of the passageway at the knife edge is smaller than the external diameter of the tube to deform same and secure it in fixed position.

Abstract: An improved lubrication connector for roller conveyors of the type which includes a pair of idlers positioned end-to-end, each idler being rotatably mounted on a hollow shaft through bearing assemblies. The shafts communicate with associated bearing assemblies which are lubricated by forcing lubricant through the hollow shafts. A flexible tube connects adjacent portions of the hollow idler shafts for transporting lubricant from one shaft to the other. The improvement includes one end of the tube being resiliently held in place relative to one of the hollow shafts so that the interior of the tube will communicate with the interior of said hollow shaft, the other end of the tube being sized and shaped slightly smaller than the interior of the other hollow shaft for allowing the tube to be inserted in the shaft yet large enough to prevent lubricant under pressure from leaking between the tube and shaft.

Abstract: The invention is a unique connector for joining the juxtaposed ends of the shafts of two adjacent conveyor idler rolls. The shaft ends are provided with diametrically extending pivots. The connecting link comprises a continuous or endless loop of relatively rigid high strength material folded over to form two pairs of spaced but parallel gudgeons, each pair of gudgeons forming a clevis. One clevis loopingly or pivotably engages the pivots attached to one idler shaft, and the other clevis similarly engages the perpendicularly aligned pivots attached to the other shaft. In one embodiment, a trunnion nut having colinearly extending pivot stubs and a threaded central opening, is screwed onto the end of each shaft. Optionally, a flexible grease tube can be passed from one shaft end through the connector to the other shaft end to provide flow-through lubrication capability.

Abstract: A series of conveyor idler roll shafts in end-to-end relation supported by bearings provides a pressurized chamber for the flow of grease or oil to the bearings from a reservoir, which is capable of pumping the lubricant into the axial bore of each shaft. Small, radially directed holes connect the shaft bores to the bearings by providing a restricted passage having across it a suitable pressure drop capable of allowing lubricant to flow in sufficient quantities to each bearing regardless of its distance from the reservoir pressure source. Adjacent shaft ends are connected with a resilient cylindrical tubular coupler to provide the requisite flow passage continuity. A labyrinth seal provides a continuous path for lubricant to flow through the bearings, the seal and ultimately to the exterior of the system, where its appearance is visible and indicative of adequate lubricant flow to each bearing along the shaft assembly.
