The outfeed assembly further includes a drive sprocket and a limiter to ensure engagement of drive elements on the conveyor belt with the drive sprockets. A limiter plate ensures proper placement of the limiter relative to the drive sprocket. The infeed assembly and outfeed assembly components may be easily mounted to and removed from the conveyor frame to facilitate replacement, cleaning or maintenance. ## Claims ### Claim 1 A conveyor, comprising: a frame including opposing side plates at an end of the conveyor, each side plate including at least one outward-facing protrusion; and a removable belt-guiding assembly mounted to the opposing side plates, the belt-guiding assembly comprising a support beam extending from a first side to a second side, arms extending from the support beam, an axle having a curved end and supported by the arms, and a rotatable nosebar mounted on the axle, wherein the removable belt-guiding assembly is mounted to the frame using the outward-facing protrusion. ### Claim 2 (depends on 1) The conveyor of claim 1, wherein the removable belt-guiding assembly comprises a first mounting plate connected to the first side of the support beam and second mounting plate connected to the second side of the support beam, each mounting plate including a slot for engaging the outward facing protrusions to integrate the belt-guiding assembly into the conveyor. ### Claim 3 (depends on 2) The conveyor of claim 2, wherein the curved end extends between a front edge of one of the side plates and the first mounting plate when the belt-guiding assembly is mounted to the opposing side plates. ### Claim 4 (depends on 1) The conveyor of claim 1, wherein the rotatable nosebar comprises a plurality of toothed, rotatable nosebar segments arranged in series on the axle. ### Claim 5 (depends on 4) The conveyor of claim 4, wherein the arms extend between the nosebar segments and each arm includes an opening for receiving the axle. ### Claim 6 (depends on 4) The conveyor of claim 4, further comprising an opening each of the side plates below the protrusions for receiving a drive shaft having at least one drive sprocket mounted thereon for driving a conveyor belt. ### Claim 7 (depends on 6) The conveyor of claim 6, further comprising a roller position limiter mounted a fixed distance away from the drive shaft to ensure engagement of the conveyor belt with the drive sprocket. ### Claim 8 (depends on 7) The conveyor of claim 7, further comprising a limiter plate connecting the drive shaft with the roller position limiter. ### Claim 9 (depends on 8) The conveyor of claim 8, wherein the limiter plate includes an upper opening for receiving the drive shaft, a lower opening for receiving an axle end of the roller position limiter and a radial slot between the upper opening and the lower opening for receiving a protrusion to selectively secure the limiter plate to a side plate. ### Claim 10 (depends on 9) The conveyor of claim 9, further comprising a handle for selectively releasing the axle end from the lower opening. ### Claim 11 (depends on 10) The conveyor of claim 10, wherein the handle comprises a pin that extends through an opening in the axle end, whereby retraction of the pin releases the axle end. ### Claim 12 A belt-guiding assembly for guiding a conveyor belt around an end of a conveyor frame, comprising: a support beam extending from a first side to a second side; a plurality of arms extending from the support beam, each arm including an opening; an axle passing through the openings, the axle having a curved end; a plurality of rotatable nosebar segments inserted in spaces between the arms and mounted on the axle. ### Claim 13 (depends on 12) The belt-guiding assembly of claim 12, further comprising: a first mounting plate including at least one slot; a second mounting plate opposing the first mounting plate and including at least one slot, wherein the support beam extends between the first mounting plate and the second mounting plate. ### Claim 14 (depends on 13) The belt-guiding assembly of claim 13, wherein the first mounting plate includes an upper slot and a lower slot for engaging first and second protrusions on the conveyor frame. ### Claim 15 (depends on 12) The belt-guiding assembly of claim 12, wherein the nosebar segments each include a plurality of peripheral teeth for engaging a conveyor belt. ### Claim 16 A conveyor, comprising: a frame; a positive-drive, low tension conveyor belt trained around an infeed portion and an outfeed portion, the outfeed portion comprising: a belt-guiding assembly comprising a rotatable nosebar for guiding the conveyor belt from a carryway to a returnway; a drive mounted on a drive shaft below the belt-guiding assembly; a roller limiter mounted a fixed distance away from the drive to ensure engagement of the conveyor belt with the drive; and a limiter plate for connecting the roller limiter to the drive, the limiter plate comprising an upper opening for receiving the drive shaft, a lower opening for receiving an axle end of the roller limiter and a radial slot between the upper opening and the lower opening that engages a protrusion in the frame to allow radial adjustment of the roller limiter. ### Claim 17 (depends on 16) The conveyor of claim 16, further comprising a handle for selectively securing the limiter plate to the roller limiter. ### Claim 18 (depends on 17) The conveyor of claim 17, wherein the handle includes an eccentric pin and the axle end of the roller limiter includes a vertical slot that receives the eccentric pin. ### Claim 19 (depends on 17) The conveyor of claim 17, wherein the handle includes a first pin that passes through the limiter plate and a second pin that engages an opening in roller limiter. ### Claim 20 (depends on 19) The conveyor of claim 19, wherein the handle includes a third pin that cradles the bottom of the limiter plate.
