As the parts rotate along the circuit, electropneumatic regulators set, and PLC-controlled pressure switches confirm pressure settings on every staking cycle, ensuring that the proper pressure is applied each time, as specified by the product number. Variables that can’t be verified electronically are verified by the vision system, preventing the introduction of human error. 

Robot Always Focused

The next step in preventing errors is off-loading via the robot. The PLC analyzes feedback from every measured variable and provides the robot with good/bad part information. The robot then discards any bad parts first, virtually eliminating mishap potential as a bad part is never carried over the conveyor leading to the finished-parts container. Should a sensor fail, multiple layers of programming back-checks stop production and automatically signal the robot to discard any suspect product.

Cell designers included the robot as an additional means to eliminate human error.

“A person might make errors due to the repetitive nature of the off-loading task,” says Volz. “The robot doesn’t lose focus or become fatigued.” MF
