  • Publication number: 20090095599
    Abstract: A belt module with embedded rollers retained in cavities in the module by retention structure insertable into the module. The rollers and cavities are elongated in the direction of belt travel and closely separated by narrow dividers that form outward-facing surfaces that can serve as bearing surfaces for a belt made of the modules when the rollers are inactivated. When activated, the rollers, which rotate on axles parallel to the direction of belt travel, are supported directly on conveyor rolling surfaces. The dividers also carry the belt tension and stiffen the module.

  • Patent number: 7021452
    Abstract: Apparatus for diverting a stream of articles from one conveyor to another parallel conveyor moving in an opposite direction in a conveyor bed. A diverter element is attached to a carrier that is driven along a path parallel to the two conveyors by a differential drive mechanism coupled to the drive mechanisms of the two conveyors. The differential drive mechanism responds to the difference in the speeds of the two conveyor drive mechanisms to drive the carrier and position the driver element along the parallel conveyors. The diverter element extends at least partway across the widths of the two conveyors to guide articles on one conveyor to the other. In a preferred version, the carrier is an endless conveyor belt to which the diverter element is attached, and the differential drive mechanism includes a shaft arranged coaxially with drive or idler sprocket shafts of the conveyor belts at each end of the bed.

  • Patent number: 6601693
    Abstract: A belt conveyor with a surface layer transferred onto its article-carrying or other surface to impart certain effective properties to the surface. The belt conveyor comprises a conveyor belt driven by a belt drive along a belt-conveying path. A transfer element transfers a coating material to a belt surface along a section of the belt-conveying path. Metallic bearing surfaces in contact with the belt surface act as transfer elements from which an oxidizable metal is rubbed by the relative motion of the belt to form a high-friction metallic oxide layer on the belt surface. Another transfer element is realized by an applicator with a reservoir for storing a coating material. The applicator is positioned close to the belt surface to dispense a layer of coating material with properties that mask the inherent surface properties of the belt. In yet another version, the conveyed articles themselves serve as transfer elements.

  • Patent number: 6119848
    Abstract: A conveyor drive unit is provided for engaging and driving a belt type conveyor. The unit includes a motor drive unit and drive chain assembly having a drive chain driven by the motor along a drive path. The drive chain has drive lugs configured thereon to engage with drive dogs on the conveyor as the drive chain is driven along the drive path. The drive path defines the drive angle with respect to a straight path of the conveyor along the drive path. An adjustable positioning device is disposed relative to the drive chain assembly such that upon variable positioning of the drive chain assembly, the drive angle defined between the drive path of the chain and the straight path of the conveyor along the drive path varies. In this manner, the degree of engagement of the drive lugs with the drive dogs of the conveyor along the drive path can be adjusted by varying the drive angle.

  • Patent number: 5850902
    Abstract: This invention provides improvements in modular links and conveyor belt systems for transferring moving articles from one conveyor belt to another disposed at ninety degrees. Thus a transferring belt has specially constructed links with two integrally formed portions across the width, one for pivotable connection in a moving belt configuration and the other specially constructed with features for more effective transfer of articles from the edge of a transfer belt to a moving belt disposed at ninety degrees which excludes inter-link pivoting structure. Thus with specially formed belt edge transfer modular links, a planar edge transfer platform is formed by the upper surfaces of a series of link end and belt edge planar conveyance surfaces located on the respective belt links.

  • Patent number: 5597063
    Abstract: An article removal platform assembly with laterally movable finger plate is provided particularly suitable for abutting a conveyor belt as it passes over a sprocket wheel to remove glass articles and broken glass fragments from the belt. The generally rectangular finger plates are mounted in a lateral sliding configuration to a planar platform by at least three fasteners extending through mounting apertures through the finger plates 50, spaced to prevent lateral or longitudinal tilt. The mount has elongated fastening members adjustably aligned to let fingers mate in a conveyor belt and freely slide laterally a limited amount in either direction. Thus, the finger plates can slide side-to-side to follow belt wander when the fasteners engage ridges of the apertures through the finger plates. Also provided are snap-in caps for the apertures for maintaining a planar discharge surface having a constant coefficient of sliding friction that does not accumulate residue.
