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.

Abstract: An apparatus and method is disclosed for lubricating the spaced apart beads of a pneumatic tire prior to mounting of the tire on a wheel. A conveyor is provided for moving the tires having different outside diameters, axial widths, and central opening diameters fed in random succession along a fixed path through a lubrication station. An interceptor is positioned in proximity to the station and is moveable between a first position where tires delivered to the station by the conveyor move freely through the station, and a second position where tires delivered to the station by the conveyor engage the interceptor to stop the tires on the conveyor at the station. The interceptor stops successive tires of varying sizes to perform a lubrication operation on the tires of varying sizes when intermixed on the conveyor in random order. The interceptor is selectively moveable between the first and second position. At least one longitudinally extending, lubricating member is provided having a first axis.

Abstract: An apparatus and method for inflating a tire mounted on a wheel having first and second rims spaced apart from one another includes a reciprocal inflation head moveable along a fixed path between a first position spaced from the wheel and tire, and a second position in operable engagement with a sidewall of the tire. The inflation head has an annular sealing surface engageable with the sidewall of the tire to provide a sealed passage for introducing compressed fluid between the tire and the wheel for inflating the tire on the wheel. A floating connection allows passive angular orientation of the inflation head with respect to the sidewall of the tire as the head moves between the first and second positions to achieve sufficient contact between the sealing surface of the head and the sidewall of the tire for creating the sealed passage and for maintaining sufficient contact during inflation of the tire on the wheel to maintain the sealed passage.

Abstract: An apparatus and method for lubricating a wheel having a predetermined wheel diameter and width includes a lubricating head for encircling the wheel to be lubricated. First and second lubricating rings are supported on the head. The first and second rings have a common axis and are spaced apart an axial distance from one another complementary with respect to the predetermined width of the wheel to be lubricated. Each of the first and second rings has a diameter greater than the predetermined diameter of the wheel to be lubricated. A mechanism is provided for driving the wheel to be lubricated into operable engagement with the first and second rings of the head, such that the first and second rings of the head operably engage along an entire periphery with respect to the first and second rims of the wheel. Preferably, the mechanism rotates the wheel through at least 360.degree.

Abstract: An improved wheel alignment apparatus having a fixed support structure and a pair of cylindrical rollers communicating with the support structure, wherein the rollers support the wheels of a motor vehicle and allow rotation of the wheels while maintaining the motor vehicle in an essentially stationary position. The rollers are supported on a float plate utilizing a layer of pressurized air pumped below the float plate to allow the float plate to move along a substantially flat horizontal surface to allow the vehicle to settle into a steady rotational mode. The front of the float plates are connected through a series of linkages and a connecting rod to a linear actuator pivoting about a vertical axis. The linear actuator retracts to straighten the connecting rod which centers the float plate to a limited motion along the horizontal surface, and extends so that the connecting rod may pivot about a longitudinal axis and turn with the float plate and wheels of the vehicle.
