Abstract:
A valve stem installation system (10) includes a conveyor (24) for moving wheel (14). A controller (60) is adaptable for segmenting the wheel (14) into a plurality of sections (S1-S11). A detector (70) identifies and signals a general location of the aperture (12) to the controller (60) to identify a target section (S11) transmitted to the controller (60) by a first signal. A robotic manipulator (110, 112) is operably connected to the controller (60) and adaptable for inserting the valve stem into the aperture (12). A sensor (153) is connected to the robotic manipulator (110, 112) and is adaptable for visually identifying the target section (S11) and transmitting the general location of the aperture (12) within the target section by a second signal. The controller (60) generates a target signal transmitted to the robotic manipulator (110, 112) to increase the speed and accuracy of mating the valve stem into the aperture (12) in response to the target signal.
Abstract:
A valve stem installation system (10) includes a conveyor (24) for moving wheel rims (14). A detector (50) is cooperable with the conveyor (24) to detect size of the wheel rim (14) and a location of an aperture (12) of the wheel rim (14) to receive various valve stems (16, 18). Two robots (110, 112) are adaptable for matably moving the valve stem (16, 18) to the wheel rim (14). A controller (60) is operably communicated with the robots (110, 112) and the detector (50) for receiving a signal from the detector (50) as the detector (50) identifies configuration of the wheel rim (14) and then transmitting the signal to the robots (110, 112) thereby directing the robots (110, 112) to selectively engage the valve stem (16, 18) to be inserted into the aperture (12). An insertion tool (114) is connected to each robot (110, 112) to selectively engage the valve stem (16, 18) to interchangeably move and insert the valve stem (16, 18) into the aperture (12) in response to the signal received by the robot (110, 112) from the controller (60).
Abstract:
Universal vehicle tire valve core and cap removal installation tool includes a cap removal counterbore at one end of a cylindrical rod member and a reversible valve core engagement member positioned in a counterbore at the opposite end of the cylindrical rod member.
Abstract:
A tool for pulling a valve stem and removing the valve core of a Schrader-type pneumatic valve includes an elongate flexible shaft having opposite end portions and a handle affixed to one end portion and a valve-core engaging member including a threaded rear portion and an unthreaded forked front portion for cooperating with a flat member of a Schrader-type valve core for rotating the core to remove it from the valve. The threaded rear portion is threadable into interior threads of the valve when the core has been removed for allowing a user of the tool to pull the valve through a wheel rim opening. The front forked portion of the valve-core engaging member includes a recess formed therein for accommodating a plunger of a Schrader-type valve therein to allow the forked portion to be positioned over the plunger in the valve to provide for engagement of the cooperating forked portion of the valve core.
Abstract:
The present invention is a tire valve tool for use in servicing valve stems in tubeless pneumatic tire rims. The tool may be used to install a valve stem into a tire rim and may also be used to extract a valve stem from the tire rim. The tool includes a clamping jaw assembly at one end of an elongated handle. A lever arm attached to one of the clamping jaws serves to provide both a fulcrum point for accomplishing a mechanical advantage in pulling on the valve stem and as a lever for applying a closing force to the jaw assembly in order to grip the valve stem. The clamping jaw assembly is shaped so that valve stems in rims with recessed valve stem openings can be grasped below the main rim surface without causing damage to the rim surface. The tool preferably incorporates a non-marring material for the fulcrum end of the lever in order to minimize damage to the rim surface.
Abstract:
A method and apparatus for automatically inserting valve stems of varying sizes into wheels of various sizes in which the appropriate valve stem size is selected by analyzing images of the wheel detected by a camera. The camera is used to determine the diameter, width, and color or contrast of the wheel as well as to determine when a valve stem opening in the wheel is in a proper position for insertion of a valve stem.
Abstract:
A machine for inserting tire valves on wheel rims designed for receiving tubeless tires comprises pneumatic, electrical and/or electronic apparatus for logically programming a rim conveyor, apparatus for detaching a single rim and successively positioning same in waiting, operative and discharge positions, apparatus for exerting a pressure against the detached rim in the operative position for engagement with a rotary drive, apparatus for rotating the rim, apparatus for detecting the valve hole in relation to an axis ZZ of the emitting and receiving elements of a detection cell, apparatus for positioning the valve hole on an axis YY common to a centering spindle and to a cylinder carrying the valve to be inserted into the valve hole, apparatus for selecting a valve for each rim, apparatus for positioning the valve into the rim hole, and apparatus for holding the rim during the valve positioning operation.
Abstract:
A tool for the insertion of valve stems in the wheel rims for tubeless tires is disclosed. The tool avoids the common practice of removing the tire from the rim for replacement or insertion of the valve stem. The tool is entirely hand powered and operated and comprises a push rod slidably mounted in a body sleeve which has a tapered internal wall with a very slight included angle, less than 10*, so that the rod can be pushed with a minimum of force to compress the bulbous end of the stem until it is discharged into the hole of the rim. The discharge face of the sleeve has a tip that inserts into the hole with an outside shoulder that bears against the rim as the rod is pushed through the sleeve to steady the sleeve and hold it in place.
