Overload sensor

To ensure screws feeding continuity

It is an important device to be applied to the circular feeder aluminium bowl in order to continuously ensure system operation. The control of the screw quantity on the feeder tracks is guaranteed by an optical fibre or sensor employed with the aim to prevent screws getting stuck in the selection duct as well as machine stop. As the optical fibre detects the screws, it activates an electro-valve which is producing an air flow eliminating the excess screws. For a greater reliability and improved effectiveness in the working cycle.
