Tolerance adjuster and wear device for sortation system

A positive displacement sorter comprising:

• a plurality of interconnected slats defining an endless web, said web defining a conveying surface;
• a plurality of pusher shoes gliding along at least some of said slats to laterally displace articles on said conveying surface;
• and
• a plurality of tolerance adjustment and wear clips disposed between at least some of said slats and some of said pusher shoes, each of said clips releasably coupled to one of said pusher shoes.

A method of biasing a pusher shoe to maintain a desired tolerance between the pusher shoe and a linear slat of a positive displacement sorter, said method comprising:

• providing a positive displacement sorter having a plurality of interconnected slats defining an endless web further defining a conveying surface of the sorter, and a plurality of pusher shoes configured to glide along at least some of the slats to laterally displace articles on the conveying surface;
• providing at least one biasing and wear device between at least some of the pusher shoes and at least some of the linear slats, wherein the biasing and wear device is removably coupled to the pusher shoe;
• and
• automatically biasing an interior surface of the pusher shoe away from an adjacent exterior surface of the linear slat with the biasing and wear device.

A pusher shoe for a positive displacement sorter in which the pusher shoe is configured to move along a slat of the sorter, said pusher shoe comprising:

• a base, wherein said base includes an interior surface at least partially defining an opening in said base for receiving a slat, and wherein said interior surface includes a receiving hole;
• and
• a clip removably inserted in said receiving hole;
• wherein an end portion of said clip extends from said receiving hole when said clip is inserted in said receiving hole, and wherein said end portion of said clip is configured to contact an outer surface of the slat when said pusher shoe moves along the slat.
