| 185 | External guide assembly for reducing conveyor belt drag | US09564906 | 2000-05-04 | US06298982B1 | 2001-10-09 | James L. Layne; Wendell S. Bell; Michael D. McDaniel; Mark T. Johnson |
| An external guide assembly for reducing the frictional drag force acting on a side-flexing modular link conveyor belt, particularly along curves or bends in the conveyor system. The guide assembly is formed from one or more roller assemblies, each having first and second rollers that provide external bearing surfaces for the forward and return runs of the belt. The rollers prevent the belt from drifting to the inside of the curve, and thus serve to reduce the frictional drag force between the belt and the guide rail on the outside of the curve. To form the guide assembly, pairs of articulated members interconnect the roller assemblies and allow the relative angular position of each to be selectively adjusted for mounting along any curve. The rollers may optionally include a peripheral lip which provides additional support for the guide links of the belt. | ||||||

| A power turn conveying apparatus and method of using same is provided which includes the use of a drive belt that extends in a horizontal plane and engages drive pulleys that rotate about vertical axes and are connected by 90 degree gear boxes to horizontally extending conveyor rollers. The drive belt cooperates with the drive pulleys and gearboxes to hold the conveyor rollers to the conveyor frame while the drive belt is tensioned, and easy removal of the conveyor roller assemblies is allowed while the drive belt is untensioned. Receptacles that receive the gearboxes and bearings at the opposite ends of the conveyor rollers extend vertically and define upwardly oriented openings, so that when the drive belt is untensioned the conveyor roller assemblies can be vertically lifted from or vertically dropped into their respective positions in the conveyor system. | ||||||
| 187 | Curved conveyor section | US228411 | 1999-01-12 | US06105755A | 2000-08-22 | Ivan Muchalov |
| A curved conveyor section comprises a generally flat substantially horizontally disposed curved belt-supporting bed having first and second opposite ends and first and second direction reversing members disposed at the first and second opposite ends, respectively. A continuous loop curved conveyor belt has arcuate inner and outer edges with a common substantially vertical centre axis and is mounted on the belt-supporting bed in looped relation around the direction reversing members so as to have an article carrying portion disposed above the belt-supporting bed and a return portion disposed below the belt-supporting bed, thus defining a looped path for the conveyor belt and presenting a substantially horizontal article carrying top surface. A motor driven continuous loop drive chain or belt is oriented in a substantially horizontal plane and has a plurality of driving members disposed along its looped length. A plurality of driven receptors are securely mounted on the curved conveyor belt along its looped path. The driving members drivably engage a consecutive subset of the plurality of co-operating receptors, which consecutive subset is disposed at one of the article carrying portion and the return portion of the curved conveyor belt, so as to thereby impart a driving force to the co-operating receptors, thus causing selective movement of the curved conveyor belt along its looped path. | ||||||

The powered belt turn (10) comprises a frustoconically shaped conveyor belt (15) which is supported for rotation through an arcuate path about angularly displaced end rollers (56). The conveyor belt is selectively and preferentially stiffened by reinforcing stays adapted to the conveyor belt structure. A motor (74) is operatively attached to an end roller causing the end roller to rotate thereby rotating the conveyor belt. The conveyor belt is supported on a belt support plate (28) and maintained in engagement with the end rollers by a belt retainer. In a first embodiment, the belt retainer is a sheave belt retainer (12) comprising sheaves (96, 98) adapted to engage an inner edge (36) of the conveyor belt and to urge the conveyor belt into engagement with the end rollers. In a second embodiment, the belt retainer is a track belt retainer (112) comprising an arcuate track (150) having a track groove (152). Ball casters (39) are adapted to the reinforcing stays (40) extending from the inner edge of the conveyor belt. The arcuate track is urged into engagement with the ball casters thereby causing a retaining force to be transmitted to the conveyor belt to urge the conveyor belt into engagement with the end rollers. | ||||||
| 191 | Arcuate path chain belt harvester | US152307 | 1993-11-12 | US5415273A | 1995-05-16 | Myron A. Peterson |
| A potato harvester having an infeed conveyor and a discharge conveyor includes a curved-path corner conveyor for conveying harvested potatoes along a continuously curved path from the infeed conveyor to the discharge conveyor. The corner conveyor includes an endless arcuate belt with upper and lower flights. A corner frame supports and guides the upper flight of the endless belt in an arcuate path from an infeed end which receives potatoes from the infeed conveyor to an outfeed end which delivers potatoes onto the discharge conveyor. Upstream and downstream lower idler assemblies are positioned to support the lower flight of the endless belt at spaced locations along its length, while allowing a belt loop to form between and beneath the lower idler assemblies. A drive wheel assembly within the belt loop is downwardly biased to frictionally engage and drive the endless belt. A driven slack take-up wheel frictionally engages the lower flight of the endless belt downstream from the drive wheel assembly and provides increased friction between the drive wheel assembly and the endless belt. | ||||||
