Definitions

  • This invention relates to conveyors .
  • This invention has arisen particularly in relation to so-called corner conveyors where a conveyor belt needs to negotiate a bend in the plane of the belt, or at least partially so. At and through such a bend, it is preferred for the edge of the belt that is outermost relative to the curvature of the bend needs to be accurately located and constrained during movement of the belt round the bend. It is known from German Auslegeschrift 2055682 to so locate and constrain by way of a bead along the outermost edge of the belt, which bead is engaged by rotary guidance/constraint means in the form of pairs of wheels or rollers having axes in outwardly divergent relation one to each side of the belt at its outer beaded edge. It is also known, indeed commonplace, for the belt to be driven by rotary drive applied to one or more support rollers for the belt, typically a said belt support roller about which the belt is returned.
  • drive means for a conveyor belt having beading at an edge of the belt comprising a drive element in driving engagement with the edge beading of the belt.
  • the drive element is conveniently adjacent to the outer edge of the conveyor belt.
  • the preferred rotary guidance/constraint means may provide reaction means for the drive element.
  • the preferred rotary guidance/constraint means typically acts to some extent to tension the belt across its width, indirectly locate the inner edge of the conveyor belt, which, if also beaded, can serve for engagement by the drive element .
  • drive engagement beading could be at either edge, or both edges,- and the drive element correspondingly located.
  • the beading affording a conveyor belt drive element engagement may conveniently correspond substantially with width of a drive belt, say of preferred drive means having rotary supports spaced along the conveyor bend in affording an advantageous compact arrangement .
  • bead edges nominally flush with the outermost edge of the conveyor belt may engage the drive element directly, or may serve as supports for wear/drive enhancing addition, even such as a toothed belt, say even to cooperate with a toothed drive belt .
  • the beading surfaces substantially match to the rotating edge surface shapes of wheels/rollers, of the guidance constraint means; and/or usefully further match to the drive element at engagement therewith.
  • radially inner guidance/constraint engaging surfaces and/or the drive element engaging surface of typically elastomeric beads can be treated, coated or laminated to improve wear resistance, or; or even include incorporated substantially rigid reinforcing structures that could further serve in secure attachment by such as rivets .
  • Figure 1 is an outline plan view of a small segment corner conveyor
  • Figure 2 is an outline part-sectional view showing conveyor belt guidance constraint
  • Figures 2A, B, C are scrap outline part- sectional views of bead and guidance constraint variations ;
  • Figure 3 is an outline sectional view showing conveyor belt drive. DESCRIPTION OF ILLUSTRATED EMBODIMENT
  • a conveyor belt is required to negotiate a bend in the plane of the belt, see Figure 1 for a module or segment of conveyor belt 10 between radial support rollers 11A,B end-journalled in frame 12.
  • the frame 12 is shown conveniently presenting sides 12A,B and upper support plate 12C extending between the rollers 11A,B.
  • the frame 12 is further shown affording a return run 10B for the conveyor belt 10 in the usual way, i.e. below its load-carrying run 10A.
  • the radially outer edge 10E of the conveyor belt 10 is shown with beads 14A,B affixed to each side of the belt 10, i.e. at upper and lower edge-adjacent positions for its load carrying run 10A.
  • the beads 14A,B are further shown with radially inward edge surfaces engaged by pairs of wheels or rollers 15A,B for the load-carrying run 10A and 16A,B for the return run 10B.
  • the pairs of wheels/rollers 15A,B and 16A,B are shown in opposing spaced relation with the conveyor belt runs 10A,B passing between them.
  • the pairs of rollers 15A,B and 16A,B are fixed relative to the conveyor belt 10 for guidance and constraint purposes, see Figure 2 and various fixing brackets 17 of the frame 12.
  • the brackets 17 are in registering pairs and have various registering journals 18 assuring alignment of the rotation axes of the wheels/ rollers 15A,B or 16A,B of each pair.
  • FIGS 2A Variations of the beading are shown in Figures 2A with an added outer strip 14C over the belt edge 10E; in Figure 2B as a unitary formation 14D encompassing the bead edge 10E and presenting inclined bearing surfaces 14E, F for inclined guidance/constraint rollers 15C, D; and in Figure 3 as other sectional shape of bead 14X that could be of circular or other conic section slotted at
  • the outer drive surface could be formed to aid drive by the drive belt, including centring relative thereto, say by curved or chevron shaped cooperating formations .
  • the radially outermost surfaces of the beads 14A,B preferably serve in driving the conveyor belt 10, conveniently on its load-carrying run 10A, and preferably by a drive belt 21 of an advantageously compact drive unit 20 shown in closely edge-adjacent relation with spaced rotary drive belt carriers 22A,B.
  • Drive is indicated applied from a motor 23 through a shaft 24 journalled at 25A,B between motor support flange 26 and bearing 27 on drive support flange 28, either directly to one of the drive belt carriers 22A,B or through suitable gearing (not shown) to both if desired.
  • the drive 20 has substantial compliance, conveniently by way of a self-aligning yoke-and-tapered stud bearing arrangement 28 that allows movement with alignment action; and further by way of at least one adjustable pressure spring 29, preferably two spaced provisions near the belt carriers 22A, B respectively, ' see threaded stud 29T welded to the outer frame side 12A, and passing strapping 29S between the flanges 26, 28 against which the spring 29 acts from adjustment wheel 29W.'
  • Beads hereof can be secured at or adjacent to the edges of belts by any affective means.
