In order to automate two injection moulding machines, Decuna installed a robot that unloads the parts from the moulds and layers them in a container.

The main advantage of this system compared to robot arms installed on each injection moulding machines is the cost save implied and simplicity. The robot is able to serve simultaneously both machines.

The injection moulding machines communicate with the robot, indicating when the parts are ready to be picked up from the mould.

A part presence check is performed once the plastic parts are picked up, in order to detect any possible error during injection moulding.

The cycle time was estimated with a computer simulation. The simulation also served as a starting point for robot programming.
