1. An automated spraygun, comprising:
a spraygun body including
a plurality of first feed conduits for feeding a product to be sprayed and a pressurized gas, anda rest face into which said first plurality of feed conduits issue in the form of first orifices; a foundation including
a seating face which said rest face is to be forced against,a plurality of second feed conduits that are complementary to said plurality of first feed conduits and terminate, on one hand, into connection elements to spray product and pressurized gas feeds and, on the other hand, into second orifices in said seating face,said first and second orifices being configured in a manner that each first rest orifice coincides with a respective one of the second orifices when said rest face of the spraygun body is forced against said seating face of the foundation; seals to be inserted between said seating face and said rest face and peripherally located at each junction between the respective first and second orifices; and assembly and locking means for quick assembly and locking of said spraygun body to said foundation; wherein said assembly and locking means comprises: means for positioning said spraygun body on said seating face, said positioning means projecting perpendicularly from one of said rest and seating faces and translating orthogonally into the other of said rest and seating faces in a manner to position said rest face relative to said foundation face in a plane; a locking stub projecting perpendicularly from one of said rest and seating faces and orthogonally translating into the other of said rest and seating faces; and a barrel member for applying an axial pull on said locking stub to keep said rest and seating faces forced against each other,
wherein said barrel member is rotatable about an axis substantially perpendicular to said locking stub,wherein the rotation of said barrel member about said axis translates into said axial pull on said locking stub,wherein said barrel member comprises
an axial cavity that runs offset and parallel to the axis of the barrel member,a radial cavity intersecting with the axial cavity and having a width larger than that of a head of said locking stub,a slot disposed transverse to said barrel member and communicates with said axial and radial cavities, and wherein said slot includes a width larger than that of a rod of said locking stub but less than that of the head of said locking stub,an annular recess disposed into a circumference of said barrel in which a set screw is engaged, thereby allowing the rotation of said barrel by a fraction of one revolution. |
