I was recently working with an automation company who was looking for a way to remove reject blank keys from a 12″ conveyor. The keys are placed on the conveyor in single rows spaced roughly 1″ apart, As the keys travel down the line, occasionally there will be a key that was damaged during the stamping process and needs to be removed from the production run. We initially discussed our Super Air Knife to blow across the width of the conveyor but they wanted to focus on the various rows, providing a single blast of air to remove just single irregular keys, one at a time.
I recommended they use (6) of our Model # 1126 1″ Flat Super Air Nozzle and space the units 1″ apart to cover the width of the conveyor. The 1″ Flat Super Air Nozzle provides a 1″ wide, high velocity focused airflow. The unit is shipped with a .015″ shim installed, providing 9.8 ounces of force when operated at 80 PSIG. The shim can be changed to different thickness levels either opening or closing the gap, providing more or less force and flow to meet the demand of the application. They were also looking for a way to operate the units independently so the nozzle would only work when their sensor identified a reject key. For this independent control, I recommended they use a solenoid valve on each supply line, allowing them to operate the nozzles from their control system.
