Inventors:

- Harahan LA, US
Michael Hendrik DeGroot - Rockford MI, US
Ruizhe Ma - Grand Rapids MI, US

International Classification:

B65G 15/62
B65G 45/16

Abstract:

A conveyor employs a low-tension, direct drive conveyor belt, and a snap-on position limiter for ensuring proper engagement of the belt and a drive sprocket. The position limiter includes a body, a limiting surface and a snap clap opposite the limiting surface for snapping the position limiter to a mounting shaft. The position limiter may include a mounting arm for mounting a conveyor belt scraper at the front of the position limiter. Mounting plates at the end of the conveyor support a mounting shaft for mounting the position limiter or other conveyor components in place relative to the drive sprocket.

Inventors:

- Harahan LA, US
Ruizhe Ma - Grand Rapids MI, US

International Classification:

B65G 45/16

Abstract:

A self-biasing conveyor belt scraper for a conveyor belt trained around a sprocket includes a base mounted on a shaft below the sprocket and a tapering scraper tip extending from the base. The top of the base contacts the conveyor belt at a first location. The conveyor belt pushes against the top of the base to bias the tapering scraper tip into contact with the conveyor belt at a second location.
