Save Time and Floor Space with a Reliable Vertical Tool Change

Stamping Line Tool Change Application - Tool Changer PES

Stamping production lines are heavy industrial means that are expensive. To get the right return on investment those tools have to be used as much as possible and produce everything they can afford. That is the purpose of dies that are changed every time production flow needs to output different design of parts. Automation equipment such as robots has to adapt to these production changes and at PES, we know a way to give the robots the capabilities to adapt to this kind of change is to equip them with tool changers.


Stamping lines robots have to be lightweight to move fast and they generally handle large EOAT. Those large EOAT's have to be stored on docking stations when you use a tool changer and storing them horizontally can rapidly tend to take up large floor space areas. PES has developed the perfect tool changer solution that gives an answer to both issues. First, the tool changer on axis-6 comes with the minimum equipment that is the pneumatic and electrical interfaces, and the tool presence sensor, all the safe control equipment is placed on a dedicated box that aims at being installed on axis-3 to save robot payload. Second, the tool changer on the tool side is mounted so the EOAT can be uncoupled in a vertical position on a specially designed docking station. In conclusion, you give to the robot the tool change capability while keeping added payload at a minimum and saving floor space.
