Abstract
Abstract An object having three-dimensional surface such as an automotive vehicle body is painted by painting mechanisms movable along a transfer path near the object. Each of the painting mechansims has a plurality of paint spray guns displaceable dependent on the surfaces to be painted, the paint spray guns being adjustably located at optimum distances and angles with respect to the surfaces to be painted for applying a uniform paint coat to the object. No pain runs and sags will be formed on the coated surfaces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A method of painting an object having opposite side surfaces and an upper surface, comprising the steps of: positioning said body to remain at rest in a painting position; applying paint sprays ejected from a plurality of paint spraying means mounted on a plurality of arms to said opposite side surfaces and upper surface, wherein a plurality of paint spraying means are mounted on each said arm such that the paint sprays from each of said paint spraying means do not mutually interfere with each other; and moving said arms independently in mutually positionally displaced relation with respect to said body at rest to allow the paint spray from the paint spraying means to be coated on the surfaces of the object substantially without mutual interference of the paint sprays.
Claim 2
Independent Claim
130 words
A method of painting an object having opposite side surfaces and an upper surface, comprising the steps of: positioning said body to remain at rest in a painting position; applying paint sprays ejected from a plurality of paint spraying means mounted on a plurality of arms to said opposite side surfaces and upper surface, wherein a plurality of paint spraying means are mounted on each said arm such that the paint sprays from each of said paint spraying means do not mutually interfere with each other; and moving said arms independently in mutually positionally displaced relation with respect to said body at rest to allow the paint spray from the paint spraying means to be coated on the surfaces of the object substantially without mutual interference of the paint sprays.
Claim 3
Dependent Claim
50 words
A method according to claim 1, wherein surfaces of the object are painted in a first linear pattern by said paint spraying means while moving said arms, and unpainted areas of the surfaces of the object are subsequently painted in a second linear pattern by displacing said paint spraying means.
Claim 4
Independent Claim
152 words
An apparatus for painting an object having opposite side surfaces and an upper surface, comprising: a first painting mechanism movable along one of said side surfaces for painting said one side surface; a second painting mechanism movable along the other side surface independently of said first painting mechanism for painting said other side surface; a third painting mechanism movable along said upper surface independently of said first and second painting mechanisms for painting said upper surface; said first, second, and third painting mechanisms each includes paint spraying means for applying paint sprays to said object; and a plurality of paint spray means spaced at prescribed distances in a first direction normal to the direction in which said first, second, and third painting mechanism are movable, each of said first, second, and third painting mechanism having shifting means for shifting said paint spray means in said first direction in which they are spaced.
Claim 5
Independent Claim
152 words
An apparatus for painting an object having opposite side surfaces and an upper surface, comprising: a first painting mechanism movable along one of said side surfaces for painting said one side surface; a second painting mechanism movable along the other side surface independently of said first painting mechanism for painting said other side surface; a third painting mechanism movable along said upper surface independently of said first and second painting mechanisms for painting said upper surface; said first, second, and third painting mechanisms each includes paint spraying means for applying paint sprays to said object; and a plurality of paint spray means spaced at prescribed distances in a first direction normal to the direction in which said first, second, and third painting mechanism are movable, each of said first, second, and third painting mechanism having shifting means for shifting said paint spray means in said first direction in which they are spaced.
Claim 6
Dependent Claim
25 words
An apparatus according to claim 3, wherein said first, second, and third painting mechanisms are displaceable along independent paths, respectively, extending in said painting direction.
Claim 7
Dependent Claim
71 words
An apparatus according to claim 3, wherein said paint spray means comprises a first group of spray nozzles spaced at prescribed distances in a first direction normal to a second direction in which said first, second, and third painting mechanism are movable, and a second group of spray nozzles spaced at a prescribed distance from said first group of nozzles and displaced a prescribed interval from said first group of nozzles.
