Device for painting, spraying, enamelling or tinting of manufactured articles in general

Device for painting, spraying, enamelling or tinting of manufactured articles in general, and for chairs in particular, comprising in combination:

• carrier means carrying a spraying element and guide means supporting said carrier means to run vertically thereon, the carriage having means for imparting to said spraying element an orbital motion;
• means for holding and moving the manufactured article in front of the spraying element, said article holding means including support means movable along a path past a spraying station at which said guide means is located, a positioning means supported for rotation on said support means and movable therewith along said path, said positioning means being arranged to support said manufactured article for rotation in front of said spraying element, motor means separate from said positioning means and fixedly located at said spraying station adjacent said spraying element guide means and having a rotatable drive member, said rotatable positioning means having a rotatable driven member engageable with said drive member when the support means moves the article and positioning means into said spraying station so as to impart rotation to said article to permit said spray gun to spray different sides thereof.

Device for painting, spraying, enamelling or tinting of manufactured articles in general, and for chairs in particular, comprising in combination:

• carrier means and guide means supporting said carrier means to run vertically thereon, said carrier means including orbital motion means carrying said spraying element and actuable for imparting to said spraying element an orbital motion with respect to an axis on said carrier means wherein said spraying element maintains a substantially constant orientation with respect to said carrier means and guide means as it orbits, said orbital motion being adjustable as to the diameter of the orbit of said spray element wherein said orbital motion means includes means adjustable for varying the average distance of the orbiting spray element from said axis;
• means for holding and rotating the manufactured article in front of the spraying element at a desired spraying distance, and including means for adjusting the orientation of said article with respect to the spraying element.

• carrier means and guide means supporting said carrier means to run vertically thereon, said carrier means including orbital motion means carrying said spraying element and actuable for imparting to said spraying element an orbital motion with respect to said carriage wherein said spraying element maintains a substantially constant orientation with respect to said carrier means and guide means as it orbits, said orbital motion being adjustable, said orbital motion means comprising an arm to which the spraying element is secured, said arm being fixed rigidly to a connecting element in turn articulated to the extremities of two parallel arms each fully rotatable on fixed centers on the carrier means for continuous orbiting of said spraying element, first-mentioned arm and connecting element;
• means for holding and moving the manufactured article in front of the spraying element at a desired spraying distance and for adjusting the orientation of said article with respect to the spraying element.
