  • Publication number: 20090057108
    Abstract: A conveyor belt for following a conveyance path with straight and curved conveyance path sections is constructed of module rows of a module (10) or a plurality of modules situated side by side in the transverse direction of the conveyor belt. Adjacent module rows are connected to each other by means of connecting pins (42). Each module comprises a set (15) of first aligned spaced fingers (16) with transverse aperture (40), and also a set (19) of second aligned spaced fingers (20) with transverse aperture (44), which in general are disposed in a staggered position relative to the first fingers (16). The mutual distance between at least the three outermost fingers of a set situated side by side and having the same width in a set is greater than the mutual distance between fingers situated side by side at a distance from the abovementioned at least three outermost fingers. A shorter run-in length and run-out length of a curved conveyance section of the conveyance path is achieved in this way.

  • Patent number: 7494006
    Abstract: A modular conveyor belt and belt attachment members that are retained by hinge rods. The attachment members have a body with opposite outer and base surfaces. Interaction elements, such as high-friction surfaces, plates, or holddown wings, extend from the outer surface. The base surface mounts flush against a conveying surface or an opposite surface of the belt. Legs extend directly from the base surface into gaps between hinge elements extending longitudinally outward of conveyor belt modules forming the belt. Feet at distal ends of the legs hook under hinge rods to retain the attachment member firmly in place. The lateral spacings between the legs are related to the geometry of the hinge elements to register the attachment element with respect to the belt.

    Abstract: A plate-link chain made up of a plurality of parallel plates arranged in rows extending in the running direction of the chain. The plates form chain links that are connected to adjacent chain links at a hinge joint. Elastically deformable damping plates extend parallel to the plates and interconnect adjacent chain links with each other elastically to allow bending movement of the chain as it passes around a wheel. The damping plates serve to damp strand vibrations that develop in the chain strand that extends between pulleys or gears about which the chain passes.

    Abstract: A unitary modular link or link section for use in forming a rodless conveyor belt or a section thereof is provided. The link section includes a plurality of laterally-repeating link-shaped portions, each including an apex portion and a pair of leg portions. Each apex portion includes a receiver for receiving an integral first connector extending between the leg portions of a next-adjacent link or link section, preferably in snap-fit engagement, such that relative pivoting movement is established. A second integral connector maybe provided between the leg portion of each adjacent apex portion to create an engagement surface for a tooth of a drive or idler sprocket. The underside surface of each link section may also be specially contoured or curved to facilitate smooth passage over a guide structure.
