  • Patent number: 5630495
    Abstract: A conveyor diverter system comprising one or more conveyors, components for diverter systems having friction-enhancing outer surfaces, friction-enhancing layers and compositions that provide such surfaces are disclosed. In addition, methods of reducing the frequency or occurrence of articles being misdiverted by use of such systems, components, layers and compositions are described. The preferred embodiment of the friction-enhancing layer and composition disposed on the outer periphery of the diverter components comprises grit materials dispersed in a metallic material such that a particular grit surface density is achieved and grit particles protrude above the uppermost surface of the metallic layer within a range of particular distances.

  • Patent number: 5415281
    Abstract: An article unscrambler and aligner is disclosed which receives articles of different sizes in random order and position, and using plural side-by-side lanes each of which lanes has driven article transport rollers at different speeds, which speeds are uniform for the length of the lane, but are progressively higher in each lane toward one side of the unscrambler in order to provide a lateral linear speed increase. This speed increase causes separation and rotation of the articles and also causes them to arrange in single file along one side of the unscrambler's surface and so discharge them onto a conveyor at the end of the unscrambler remote from that at which the articles were received. One or more lanes are composed of rollers of tapered diameter in order to make the lateral speed increase more uniform.

  • Patent number: 4878578
    Abstract: The specification discloses a split-cam conveyor roller assembly including a pair of eccentric rollers rotatable relative one another between transportation and accumulation positions. A pin fixed in one roller is received within a circumferential slot in the other roller. A magnet is fixed at one end of the slot, and the pin is made of a ferrous material to aid in retaining the rollers in the transportation position.

  • Patent number: 4738347
    Abstract: The operating characteristics of a diverter having a driven article conveying surface of parallel tubes on which article diverting shoes are caused to move across progressively because of contract between a depending drive pin on each shoe and a laterally inclined rail beneath the conveying surface by changing the shape of the rail contacting roller on the pin so that a downward force vector is created tending to hold the shoe down. Also, the shoe is supported on three rollers instead of two to prevent the tendency of the shoe to pivot about one tube due to article resistance to lateral movement. The design of the openings in the shoe through which the tubes pass are such that the shoe will not become bound between two tubes which are not entirely straight.

  • Patent number: 4564105
    Abstract: A transfer for conveyors has a spiral shaped sweep which is rotated to cause it to engage selected articles on a conveyor and push them off laterally. The sweep is supported on and rotated by a shaft which is inclined to the vertical and toward the conveyor whereby the circular path traced by its outer end is in an inclined plane and as it moves to its retracted position it moves upwardly. As it moves across the conveyor it has a zone of maximum approach to the conveyor surface which moves across the conveyor surface and outwardly along the sweep as the sweep rotates to its maximum extended position.

  • Patent number: 4458809
    Abstract: A conveyor drive chain is equipped with pads of a high friction, resilient material. Each pad has a body secured to and overlying one link of the chain and has an extension at each end overlying the adjacent chain link. The extensions are wedge shaped, lengthwise of the chain, having one side face extending at an angle to the axis of the chain whereby the extension portions of two adjacent pads are seated side-by-side with the line of separation between them laterally inclined across the chain.

  • Patent number: 4284186
    Abstract: A conveyor for sorting and arranging in single file randomly received articles is disclosed. The unscrambling device has an acticle conveying surface consisting of skewed rollers divided into a number of zones arranged in tandem along the conveyor. The rollers in each zone from infeed to discharge are driven at increasingly higher speeds with the zones overlapping in such a manner that abrupt speed changes occur in steps both lengthwise and laterally of the conveyor. The articles are biased to one side of the conveyor which side is equipped with an article contacting rail divided into segments at least some of which are inclined to impart a jostling effect to the articles.

  • Patent number: 4252234
    Abstract: A floating support for a pair of parallel conveyor propelling members provides propelling member supporting sheaves mounted in pairs at each end of a bracket. The bracket is seated on a plurality of resilient elements such as compression springs, each of which is free for independent reaction permitting the bracket to tilt either laterally or lengthwise of the propelling members to provide uniform pressure against them at each of the sheaves.

  • Patent number: 4241825
    Abstract: An improvement in conveyors is disclosed in which the conveyor rollers are mounted in bearing blocks designed to pivot about a vertical axis and, thus, adjust to the angular relationship between the rollers and their supporting frame. The bearing blocks also provide a wear resisting and noise suppressing support for the roller shafts.
