Abstract
A noseroller assembly for transitioning a conveyor belt at an end of a carryway comprises offset bearings for guiding a conveyor belt. A first set of bearings protrudes slightly from the end of the noseroller substrate to guide the conveyor belt around the noseroller and a second set of bearings in recessed from the end of the noseroller substrate to prevent wear.
Claims10
A noseroller assembly for transitioning a conveyor belt at an end of a carryway, comprising:
- a substrate having an upper surface upon which the conveyor belt rides and a rounded front edge marking the end of the carryway;
- a first set of bearings rotatably mounted to the substrate and rotatable about axles aligned along a first lateral axis, the first set of bearings having outer surfaces that protrude beyond the rounded front edge by a first selected distance;
- and
- a second set of bearings rotatably mounted to the substrate and rotatable about axles aligned along a second lateral axis spaced from the first axis, the second set of bearings alternating with bearings in the first set and having outer surfaces that are recessed from the rounded front edge by a second selected distance, wherein the first set of bearings and the second set of bearings have top surfaces that are substantially flush with the upper surface of the substrate.

A noseroller assembly, comprising:
- a substrate having a top surface, a pair of sloping recesses extending forward from the top surface at side edges of the substrate, and a rounded front edge;
- a first bearing slot in the substrate between the pair of sloping recesses for rotatably mounting a bearing;
- a substantially vertical axle slot intersecting the first bearing slot for receiving axle of the bearing;
- rounded lips between the first bearing slot and the rounded front edge, the rounded lips extending past the rounded front edge;
- and
- a first bearing mounted in the first bearing slot such that the front surface of the first bearing is recessed from the rounded front edge, wherein the first bearing has an axle received in the substantially vertical axle slot.

A noseroller assembly for a conveyor belt, comprising:
- a first bearing module having an upper surface, a first side edge, a second side edge, a rounded front edge, a rear edge, a bottom and an opening in the upper surface for receiving a bearing;
- a first bearing mounted in the opening of the first bearing module and protruding past the rounded front edge by a first selected distance;
- a second bearing module adjacent the first bearing module having an upper surface, a first side edge adjacent the second side edge of the first bearing module, a second side edge, a rounded front edge, a rear edge, a bottom and an opening in the upper surface for receiving a bearing;
- a second bearing mounted in the opening of the second module and recessed from the rounded front edge by a second selected distance;
- and
- a connector for connecting the first bearing module and the second bearing module so that the rounded front edges align with each other.
