ABSTRACT:
The specification discloses an apparatus (10) for handling and spraying a fluid on a tire (12) in which a plurality of arms (32, 33, 34 and 35) rotate about a center axis with a head (46, 48, 118 and 176) mounted on the distal end of each arm. A tire grasping finger set (56) is mounted on each head. The finger set (56) is operable to grasp a tire, move it in a circular path into a spray station, spin the tire while spraying the interior and exterior thereof, move the tire to an idle station, move the tire to a discharge station and then discharge the tire onto a conveyor table (114). A rotary indexer (32) is used to rotate the radial arms (32, 33, 34 and 35) with the indexer causing the arms to pause at 90 degree intervals. When the rotary indexer causes a pause, a clutch is disengaged to disengage the drive of an electric motor (26) from the rotary indexer, and a brake is applied to hold the position of the arms fixed for a time interval. After such time interval, the brake is disengaged and the clutch is reengaged so that the motor (26) will drive the radial arms 32, 33, 34 and 35 through a radial distance of 90 degrees before pausing again.
