Patent number: 10427880Abstract: 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.Type: GrantFiled: September 5, 2018Date of Patent: October 1, 2019Assignee: Laitram, L.L.C.Inventors: Jeff Batchelder, Michael Hendrik DeGroot, Friso Antonius Maria Oonk, Laurentius G. J Wolters, Edward T. Mol, Ruizhe Ma

Patent number: 9840374Abstract: 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.Type: GrantFiled: June 15, 2016Date of Patent: December 12, 2017Assignee: Laitram, L.L.C.Inventor: Ruizhe Ma
