Abstract: A system for turning over a vehicle frame defining openings and having a longitudinal center axis includes first and second robots each having an end effector. Each end effector has a pair of oppositely-positioned locator pins, at least one of which is selectively moveable toward the other. A controller is used to control the positioning of the frame via the robots and end effector by executing method instructions to cause the robots to align the locator pins of the end effectors with the openings of the frame, and to insert the aligned locator pins into the openings toward the center axis from outside of the vehicle frame. The robots lift the frame from a first conveyor, with weight of the vehicle frame born by the locator pins during the lift. The robots also rotate the frame about the center axis and lower the vehicle frame onto a second conveyor.

Abstract: A method and a tool are provided for adjusting a skillet conveyor drive having a motor-driven drive wheel mounted on an adjustable mounting mechanism including a threaded rod that is biased toward the skillet by a spring mechanism and wherein the compression of the spring is adjusted by rotating an adjusting nut. The method includes pulling on the threaded rod, measuring the force required for the pulling by reading a load cell indicator, using a look up table to correlate the measured force with a desired force, and then adjusting the nut to achieve the desire force. The tool can be removed and then moved to another skillet conveyor drive.
