US Patent 10543989 Belt conveyor with automated in-line tension control system

A belt conveyor with automatic in-line tensioning. A tensioner bar is slidably received into a tensioning slot and guided by a plurality of rails. At least one air spring is positioned between the tensioner frame and the tensioner bar. The first air spring pushes the tensioner bar such that movement of the tensioner bar moves the end roller to affect a tensioning force upon the endless belt. An air pressure gauge can display an air pressure value corresponding to a tension force of the endless belt. A tracking assembly allows tracking of the endless roller independent of the tensioning. A controller can controls the tensioning and release of tensioning based on operational or environmental factors.
