SKEWED SLAT CONTROL SYSTEM FOR ARTICLE CONVEYOR
First Claim
1. A method of monitoring a positive displacement article sorter, said article sorter including a frame, an endless web traveling in a longitudinal direction about said frame and an electric motor driving said endless web, said endless web defined by a pair of continuous chains and a plurality of cross members connected at opposite ends with said chains, said positive displacement sorter further including a plurality of pusher shoes, each laterally traveling along at least one of said cross members, said method comprising:
- providing a sensing assembly having first and second portions, positioning said first portion of said sensing assembly at said web, and positioning said second portion of said sensing assembly at a stationary location;
sensing said first portion of said sensing assembly with said second portion of said sensing assembly as said first portion of said sensing assembly travels about said frame; and
determining a parameter of said web from an output of said sensing assembly.

Abstract
A positive displacement article sorter and method of monitoring a positive displacement article sorter, wherein the article sorter includes a frame, an endless web traveling in a longitudinal direction about the frame and an electric motor driving the endless web. The endless web is defined by a pair of continuous chains and a plurality of cross members connected at opposite ends with the chain. The positive displacement sorter includes a plurality of pusher shoes, each laterally traveling along at least one of the cross members. A sensing assembly is provided that has first and second portions. The first portion of said sensing assembly is positioned at the web. The second portion of said sensing assembly is positioned at a stationary location. The first portion of said sensing assembly is sensed with the second portion of the sensing assembly as the first portion of said sensing assembly travels about the frame. A parameter of the web is determined from an output of the sensing assembly.
