LIFTING FROM ROBOT WELDING JIGS - MATERIALS HANDLING
HOW AN AUSTRALIAN ENGINEERING COMPANY SOLVED HANDLING ISSUES OF LIFTING MANY TYPES OF WELDED ASSEMBLIES OFF A ROBOTIC WELDING JIG
PROBLEM: An Australian Engineering based company makes 52 varieties of tow-bar assemblies. These welded assemblies weighing up to 40kg have to be taken off the welding jigs after robotic welding, then rotated or inclined depending on type and positioned onto an overhead conveyor.
“Lifting each of the smaller parts onto the robot welding jig was not a problem for us” said the Project Manager. “The problem was lifting the heavier and more awkward completed pieces off the welding jig. The assemblies were long and heavy. Our concern was the health and safety of our people. Without lifting equipment, the completed assemblies needed 2 people to lift and with manual handling there is always the concern of accidents” said the Project Manager.
ANALYSIS: The job was given to Posilift Australia to solve. For product control, the task needed a rigid arm machine and a tooling with different gripping points. We could not use standard sliding grippers, because of all the clamps and other obstructions on a robot welding table. Finding a common gripping point for all 52 assemblies on a robotic welding jig full of clamps and other obstructions was the challenge.
SOLUTION: Posilift Australia Australia conceived a novel approach. “For this project we designed the gripper differently. We designed the gripper so it could slide to different positions on the one axis as is normal. But in addition, the gripper could also be rotated and totally re-positioned so it could also grip from many different axes. This allowed us to cover all the combinations on the welding table.” said Andy Heard, National Sales Manager. “Once the product was gripped, the rest was standard for Posilift Australia. The operator could turn or incline the product as needed. Also high and low controls were included so there is no stretching when positioning the product on the overhead conveyor.”
“We are very happy with the result” said the Project Manager. “We now have six Posilift Australia machines in operation – 4 taking the off the welding jigs and positioning onto the overhead conveyor for painting, and 2 taking finished products off the overhead conveyor and positioning into a carton.”
