Definitions

  • the subject invention relates to the assembly of wheels, and more particularly to an apparatus and method for locating a valve stem aperture in a wheel and mounting the valve stem to the wheel.
  • U.S. Patent No. 6,481,083 teaches a valve stem assembly line that includes an input conveyor to supply wheels, a locator station positioned at the end of the input conveyor to locate the valve stem aperture defined by the wheel, and a robotic manipulator to grasp the wheel in the locator station and to move the wheel to the mounting station where a valve stem is inserted.
  • U.S. Patent No. 6,026,552 teaches a spinning device to spin the wheel, an optical sensor to locate the valve stem aperture while the wheel is spinning, and press fitting device that can slide relative to a wheel and insert a valve stem after the valve stem aperture has been located.
  • U.S. Patent No. 5,940,960 teaches and automatic valve stemming apparatus including a spinning device to spin the wheel, an optical sensor to locate the valve stem aperture, and a valve stem insertion tool to insert a valve stem after the valve stem aperture has been located.
  • the invention provides an apparatus and method for locating a valve stem aperture in a wheel and inserting the valve stem in the valve stem aperture.
  • the valve stem and the valve stem aperture are moved relative to one another at a predetermined relative speed in a first rotational direction along a curved path of the wheel perimeter to align the valve stem with the valve stem aperture.
  • the valve stem is supported with a pin and the pin is moved around the wheel with a robotic apparatus.
  • a first sensor locates the valve stem aperture when the valve stem and the valve stem aperture are a first angular distance from one another along the curved path.

  • a second sensor locates the valve stem aperture when the valve stem and the valve stem aperture are a first angular distance from one another along the curved path.
  • One of the advantages of the present invention is that processing time for inserting the valve stem in the valve stem aperture is reduced. Specifically, the relative movement between the valve stem and the valve stem aperture can be maximized prior to the locating step and the first and second sensor can be spaced from one another to accommodate the braking capacity of the system. In other words, the invention substantially eliminates time delays associated with confirming the location of the valve stem aperture that are common in prior art locating systems.

Abstract

L'invention concerne un système d'installation d'une tige de soupape, comprenant un bras de robot permettant le déplacement d'un dispositif d'insertion d'une tige de soupape autour du bord d'une roue. Le système comprend également une paire de détecteurs d'ouverture de tige de soupape, positionnée sur le bras du robot adjacent au dispositif d'insertion, et déplaçable autour du bord de la roue. Les détecteurs peuvent être positionnés sur les côtés opposés du dispositif d'insertion de tige de soupape. Lorsque le premier détecteur localise l'ouverture de la tige de soupape, le mouvement du bras de robot peut être ralenti. Lorsque le second détecteur localise l'ouverture de la tige de soupape, le mouvement du bras du robot peut être stoppé. L'unité convoyeuse peut comprendre un poste d'identification destiné à détecter la configuration de la roue. Un contrôleur peut sélectionner la tige de soupape appropriée qui doit être insérée dans l'ouverture de tige de soupape, en réponse à la configuration détectée de la roue.
