Abstract

A conveyor employs an infeed assembly and outfeed assembly, each comprising a nosebar assembly that may be mounted to a conveyor frame to transition a conveyor belt between a returnway and a carryway, a belt guiding roller, such as a sprocket or brake, a position limiter for ensuring proper engagement between the belt guiding roller and the conveyor belt and a connecting plate that ensures proper placement of the position limiter relative to the guide roller. The infeed assembly and outfeed assembly components may be easily moved into engagement and out of engagement to facilitate replacement, cleaning or maintenance.

First claim

What is claimed is:

1. An assembly for a conveyor, comprising:
a first side plate;
a second side plate opposing the first side plate;
a first roller extending between the first side plate and the second side plate for engaging a drive side of a conveyor belt;
a connecting plate mounted to the side plate and having a first seat for receiving an axle end of the first roller, and a second seat that is open;
a position limiter for ensuring proper engagement between the drive side of the conveyor belt and the first roller, the position limiter having a first end configured to be received in the open seat; and
a handle connected the position limiter, the handle movable between an operating position in which the position limiter end is mounted in the open seat and a nonoperating position, in which the position limiter end is unseated from the open seat.

2. The assembly of claim 1 , wherein the open seat faces a direction that is perpendicular to the axis of the first roller and the axis of the position limiter.

3. The assembly of claim 2 , wherein the open seat faces a direction that is perpendicular to a reference line between the axis of the first roller and the axis of the position limiter.

4. The assembly of claim 1 , wherein the position limiter is connected to an auxiliary component, such that movement of the position limiter translates into movement of the auxiliary component.

5. The assembly of claim 4 , wherein the auxiliary component is a scraper assembly comprising scraper blade mounted on a base and at a mounting arm connected to the base for mounting the scraper assembly to the position limiter.

6. The assembly of claim 5 , wherein the mounting arm comprises an outward extending protrusion that is received in an opening of the connecting plate.

7. The assembly of claim 1 , wherein the position limiter comprises a position limiter roller extending along a roller axis, the first end having a cylindrical shape, a mounting bar extending along an axis parallel to the roller axis, a mounting plate connecting the mounting bar to the first end and a protrusion extending outward of the mounting plate and into an opening in the connecting plate.

8. The assembly of claim 7 , wherein the handle connects to the protrusion on the mounting plate and the protrusion forma a pivot point for the handle.

9. The assembly of claim 4 , wherein the auxiliary component comprises a take-up roller and the connecting plate includes a slot for receiving an axle end of the take-up roller.

10. The assembly of claim 1 , further comprising a bearing for bearing connected to the connecting plate for receiving the axle end of the first roller.

11. The assembly of claim 1 , wherein the first roller is a brake for selectively tensioning a portion of the conveyor belt.

12. The assembly of claim 1 , wherein the first roller is a sprocket for driving the conveyor belt.

13. The assembly of claim 1 , further comprising a noseroller assembly mounted to the first and second plate, the noseroller assembly comprising:
a plurality of arms extending from a support, each arm including an opening aligned with openings in the other arms;
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.

14. The assembly of claim 13 , wherein each arm comprises a threaded base and an enlarged middle portion, and the support includes an opening having an upper chamfer for receiving the threaded base and enlarged middle portion.

15. The assembly of claim 14 , further comprising a fastener having a threaded opening for mating with the threaded base of an arm to secure the arm to the support, wherein the enlarged portion has a bottom surface that does not match the shape of the chamfered opening, so that tightening of the fastener causes the enlarged portion to deform to match the chamfered opening, thereby compressively sealing the first component to the second component.
