ABSTRACT:
The automatic paint spray gun is for industrial applications involving use with industrial robots. The spray gun comprises a housing including a tubular extension; an air cap mountable onto the tubular extension of the housing; a nozzle disposed within the air cap; and a device for adjusting the flow of air through the housing independent of the air cap. The paint is supplied under pressure to a paint discharge orifice in the nozzle through a first passage. The first passages is essentially centrally disposed within the tubular extension. The atomizing air is supplied to the paint discharge orifice through a second passage to control the atomizing of the paint spray gun. The atomizing air is supplied to the nozzle through a second passage. The second passage is supplied through an annular chamber in the tubular extension, the annual chamber being disposed radially outwardly from the first passage. The fanning air is supplied to the fan discharge openings through a plurality of passages in the tubular extension, the fanning are controlling the fanning of the paint spray. The fanning air is supplied through the plurality of passages disposed radially outwardly from the annular chamber. In addition, the fanning of the paint spray may be regulated independently of the rotative position of the air cap with either turbine air or compressed air.
