Curvable conveyor roller support
View Patent ↗A curvable roller conveyor support, for supporting a longitudinally spaced apart array of transverse roller axles, the support comprising: a dentate elongate plate being laterally symmetric about a longitudinal centerline and having a plurality of lateral edge cutouts defining a plurality of longitudinally spaced apart opposing pairs of transverse arms, each arm having: a proximal end joined to an adjacent arm with a web having a plurality of central narrowed waist portions; and a distal end bent upwards defining a flange with a roller axle mount; and an elongate base secured to an underside surface of the dentate plate, whereby the central narrowed waist portions are bent and/or twisted during mounting to the base to follow a curved line in two or three dimensional space.
1. A curvable roller conveyor support, for supporting a longitudinally spaced apart array of transverse roller axles, the support comprising:
a dentate elongate plate being laterally symmetric about a longitudinal centerline and having a plurality of lateral edge cutouts defining a plurality of longitudinally spaced apart opposing pairs of transverse arms, each arm having: a proximal end joined to an adjacent arm with a web having a plurality of central narrowed waist portions; and a distal end bent upwards defining a flange with a roller axle mount; and
an elongate base secured to an underside surface of the dentate plate.
2. The curvable roller conveyor support according to claim 1 , wherein the plate is secured to the base and the waist portions of the web are bent in one of: the plane of the plate; and a plane orthogonal to the plane of the plate, whereby the longitudinal centerline of the plate follows a two dimensional shape.
3. The curvable roller conveyor support according to claim 2 , wherein the two dimensional shape has at least a part selected from the group consisting of: a straight line; a circular line having a constant radius of curvature; a spiral line having a varying radius of curvature; and a parabolic line.
4. The curvable roller conveyor support according to claim 1 , wherein the plate is secured to the base and the waist portions of the web are twisted about the centerline of the plate whereby the longitudinal centerline of the plate follows a three dimensional shape.
5. The curvable roller conveyor support according to claim 4 , wherein the three dimensional shape has at least a part selected from the group consisting of: a circular helix having a constant radius of curvature; and a spiral helix having a varying radius of curvature.
6. The curvable roller conveyor support according to claim 4 , wherein the arms are banked.
7. The curvable roller conveyor support according to claim 1 , wherein the web has a longitudinally spaced apart plurality of openings.
8. The curvable roller conveyor support according to claim 7 , wherein the openings have at least one notch aligned with the longitudinal centerline of the plate.
9. The curvable roller conveyor support according to claim 7 , wherein the openings have at least one notch aligned with a transverse centerline of an associated pair of arms.
10. The curvable roller conveyor support according to claim 7 , wherein the openings have diamond shape with points aligned with the longitudinal centerline of the plate and the transverse centerline of an associated pair of arms.
11. The curvable roller conveyor support according to claim 7 , wherein the web of the plate and the base are joined with welds in the openings.
