Nozzle unit for cleaning workpieces

摘要

A nozzle unit is provided which is adjustable by means of servo motors and in which an independent servo motor is provided for each adjustment coordinate. These servo motors can be controlled independently of one another. The servo motors can thereby be connected to a process computer programmed for adjusting the respective coordinate values. Preferably the nozzle unit is designed for displacement to change the distance from the surface of the mould to be cleaned, for pivoting movement of its nozzle carrier through 360 DEG and adjusting the nozzle radially to the pivot axis of the nozzle carrier by means of a feed rod.
