Abstract

A wheel soaper for spraying soap on a wheel rim includes a conveyor for conveying wheels in a horizontal position in succession to a soaping station. A downwardly facing frictional drive disc is located above the conveyor at the soaping station clear of the path of movement of wheels and is mounted for rotation about a fixed vertical axis. A cone member is mounted beneath the disc in coaxial relationship with the disc for free rotation and is driven in vertical movement by a reciprocating air motor upwardly from and downwardly to a normally maintained rest position below the path of wheels on the conveyor. When a wheel is stopped on the conveyor at the soaping station, the cone is driven upwardly into the central opening of the wheel to lift the wheel from the conveyor until the upper rim of the wheel is firmly pressed against the drive disc which is then driven in rotation as soap is sprayed from a stationary nozzle onto the rotating wheel rim. The cone provides a self centering action and a pressure regulator connected to the air motor stops further elevating movement when the wheel is clamped against the disc to enable the apparatus to soap wheels of various diameters and axial widths.

Dependent claims

Wheel soaping apparatus for spraying a soap composition onto the rims of wheels having different outside diameters, axial widths, and central opening diameters fed to said apparatus in random succession, said apparatus comprising conveying means for conveying wheels in a horizontal position along a fixed path to and from a soaping station, downwardly facing rotary drive means located at said soaping station and mounted for rotation about a fixed vertical axis at a location spaced above the path of movement of wheels along said conveying means, a downwardly divergent cone member mounted for free rotation in coaxial relationship to said first axis, means for driving said cone member in vertical movement along said axis upwardly from and downwardly to a normally maintained rest position wherein said cone is spaced below the path of movement of wheels along said conveying means, retractable stop means on said conveying means operable to stop a wheel on said conveying means at a location where said vertical axis passing through the central opening in the wheel, control means operable when a wheel is stopped at said location by said stop means for elevating said cone member upwardly from said rest position into the central opening of the wheel and to lift the wheel upwardly from said conveying means until the uppermost rim of the wheel is frictionally clamped against said drive means, and spray means operable to spray a soap composition onto the uppermost rim of said wheel when said wheel is so clamped against said drive means.
