Abstract
Turnover apparatus for the controlled turning of a flat-sided article, such as a vehicle wheel-tire unit, from a horizontal outside-up position to a horizontal outside-down position includes a chain conveyor for conveying the article in a horizontal position. A turnover device employs two pairs of elongate arms mounted for rotation about respective, spaced, parallel axes from and to a normal rest position wherein the pairs of arms project horizontally in opposite directions from their axes below and parallel to the conveying chains. One pair of arms is coupled to a reversible drive to be rotated upwardly from its rest position through an angle greater than 90.degree. to tilt an article on the conveying chains upwardly to and past the vertical by an amount such that the article, if not restrained, would fall forwardly. Motion transmitting mechanisms couple the two pairs of arms to each other so that the other pair of arms engages the falling article to lower the article to the chains upon reversal of the drive. Various forms of motion transmitting mechanisms and a safety overload release are also disclosed. A production line system utilizing the turnover device in a wheel balancing …
