A programmable, robotic manipulator capable of compound, multi-axial movement and capable of engaging the valve stem is controlled by a controller to engage a valve stem, move the valve stem to the aperture in the wheel rim, coaxially align the central axis of the aperture with the longitudinal axis of the valve stem, and insert the valve stem through the aperture along the aligned central and longitudinal axes. Optionally, the robotic manipulator may include a nut runner to tighten a nut over the valve stem. Alternately, the gauging station may include a rotating table to rotate the vehicle wheel and an optical sensor for detecting the location of the aperture for the valve stem.

Abstract: A tire/wheel bead entrapment remover is disclosed. The tire/wheel bead entrapment remover includes one or more working assemblies having a circumferential perimeter that substantially engages a tire. The one ore more working assemblies axially-moves one of a wheel of the tire mounted to the wheel while axially-fixing the other of the tire or the wheel to remove one or more entrapments between a bead of the tire and a beat seat of the wheel. According to an embodiment, a tire/wheel bead entrapment remover includes one or more wheels that engages an outboard surface or an inboard surface of a tire mounted to a wheel. The radial axis extends through the one or more wheels. The radial axis traverses a radial line that radially extends from a common axis of rotation of the tire and the wheel. A method for removing an entrapment from a tire/wheel assembly is also disclosed.

Abstract: An inflator device is disclosed. The inflator device includes a seal assembly that maintains, while sealing from ambient pressure, an open air passageway between a tire bead and wheel bead seat during an inflation procedure. A seal for the inflator device is also disclosed. The seal includes a ring-shape having a flexible inner periphery that is adapted to maintain, while sealing from ambient pressure, an open air passageway between a tire bead and wheel bead seat during an inflation procedure.

Abstract: A tire-wheel assembly adjuster is disclosed. The tire-wheel assembly comprises a working assembly adapted to be adjustable along an axis relative a workpiece and a sub-assembly coupled to the working assembly that is adapted to be radially adjustable relative the axis. A method for assembling a tire-wheel assembly is also disclosed. The method includes the steps of providing a tire in an un-mounted state relative a wheel to a tire-wheel assembly adjuster; moving a sub-assembly connected to a working assembly in a radial direction relative an axis; moving the working assembly in a first direction about the axis toward the tire and wheel; and causing a wheel adjuster extending from the sub-assembly to circumferentially seat a bead of the tire into a bead seat of the wheel.

Abstract: An apparatus and method for mounting a valve stem to the rim of an vehicle wheel includes engaging a valve stem with a robotic manipulator, moving the valve stem relative to the rim along a programmable path of travel, coaxially aligning the valve stem with the aperture in the rim, and inserting the valve stem through the aperture in the rim. Preferably, the aperture location in the rim is determined at a gauging station by a machine vision system. If necessary, a power-actuated nut runner is used to tighten a nut over the valve stem. Alternately, the gauging station can use a table which rotates the wheel about a central axis, and an optical sensor detects the location of the aperture. Optionally, a probe mounted on the gauging station can be extended into the aperture to confirm the aperture position and to reposition the rim slightly if required.

Abstract: An apparatus and method for mounting a valve stem to the rim of an automotive vehicle wheel includes rims being supplied in series by a conveyor to a gauging station where the type and/or size of the rim and the location and alignment of an aperture for receiving the valve stem is determined by a machine vision system. An electronic control system directs a robotic manipulator to grasp either the valve stem or the rim, move the valve stem or the rim to a mounting station, position the valve stem or the rim with respect to the other such that the aperture in the rim is in coaxial alignment with the valve stem, and insert the valve stem through the aperture in the rim. If necessary, a power-actuated nut runner, mounted on the robotic manipulator or adjacent the mounting station, is used to tighten a nut over the valve stem.

Abstract: In an automated method for mounting a valve stem to the rim of an automotive vehicle wheel, rims are supplied in series by a conveyor to a gauging station where the location and alignment of a hole for receiving the valve stem is determined by a machine vision system. An electronic control system directs a robotic manipulator to grasp the rim, move it to a mounting station where a valve stem is retained, position the rim such that the hole is in alignment with the valve stem, and urge the rim toward the valve stem to insert the valve stem through the hole in the rim. If necessary, a power-actuated nut runner, mounted on the robotic manipulator or adjacent the mounting station, is used to tighten a nut over the valve stem to secure. As an alternative to the machine vision system, the gauging station may utilize a rotating table which rotates the wheel about its central axis, and an “electric eye” optical sensor which directs a beam of infrared light onto the rim.

Abstract: A system for accurately mixing two or more liquids and for dispensing the mixture. The system is generally adapted for use in paint spraying operations. The flow of one of the components is accurately measured by means of a flow meter and the measured value provides a signal to control a valve which, in turn, controls the flow of the other liquid. Periodically the volume of the first mentioned liquid is measured for a given time period so as to make necessary adjustments in the flow meter-valve interconnection. An improved arrangement is provided for purging a mixing manifold immediately prior to the completion of the dispensing cycle so that none of the mixture will be wasted. The control arrangement includes improved air operated two and three-way valves.
