Abstract

A tire mounting apparatus for mounting a flexible tire on a rim includes a robot having at least one articulated joint and a wrist. The robot is moveable with at least three degrees of freedom along a selectable one of a plurality of programmable predetermined paths. A central processing unit selectively executes any one of the plurality of paths stored in memory. A bead mounting tool is attachable to the wrist of the robot for movement along the selected one of the plurality of programmable predetermined paths of the robot. The tool is orientatable with at least three degrees of freedom independent of the selected one of the plurality of programmable predetermined paths. A workpiece support positions the rim in a predetermined location with respect to the robot and positions the tire in a predetermined orientation with respect to the rim. A signal is generated and sent to the robot corresponding to a size of the rim and tire combination to be assembled. The central processing unit selects one of the plurality of predetermined paths corresponding to the rim and tire size combination. The robot includes one or more sensors for measuring load on the articulated joint arid wrist during a tire mounting cycle. The control program includes a sensor monitoring function for stopping movement of the tool in response to a load greater than a predetermined value. A clamp member prevents rotation of the tire with respect to the rim as the tool works a bead of the tire over the rim.
