Abstract
Abstract An automatic system for painting the interiors of vehicle bodies having a large opening at the rear, particularly industrial vehicles, including a mechanism which supports two electrostatic paint sprayers and which is designed to move these according to three movements which respectively modify their spacing, their distance from the axis and their overall position relative to the axis. Handling equipment produces a fourth movement consisting of a controlled backward and forward movement of the vehicle body along the vehicle axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
285 words
An apparatus for painting the interiors of vehicle body enclosures, comprising: first means for supporting a vehicle and moving said vehicle along a first axis; two electrostatic paint sprayers; second means for supporting said sprayers along a second axis transverse to said first axis; third means for varying the relative mutual positions of said sprayers; fourth means for varying the distance of said sprayers relative to said first axis; and fifth means for varying the angular circumferential position of said sprayers about said first axis, whereby said sprayers may be positioned so as to paint the entire interior of said vehicle, wherein said second means comprises a fixed support; said fifth means comprises a cradle mounted on said fixed support for rotation about said first axis; said fourth means comprise a box beam pivotally mounted on said cradle about a third axis transverse to said first and second axes, and means for controlling the angular position of said box beam about said third axis; wherein said third means comprise a cross piece mounted parallel to said third axis on an end of said box beam opposite said cradle, two arms, one end of each said arm pivotally mounted on each end of said cross piece about parallel fourth axes, said arms extending in a common plane and said sprayers mounted on the other end of each said arm, and servomotor means for pivoting each said arm about a respective fourth axis, and wherein said cross piece is rotatable about a fifth axis parallel to the length of said cross piece, said apparatus including an articulated link pivoted between said cradle and said cross piece, wherein said common plane is always parallel to said first axis.
Claim 2
Independent Claim
285 words
An apparatus for painting the interiors of vehicle body enclosures, comprising: first means for supporting a vehicle and moving said vehicle along a first axis; two electrostatic paint sprayers; second means for supporting said sprayers along a second axis transverse to said first axis; third means for varying the relative mutual positions of said sprayers; fourth means for varying the distance of said sprayers relative to said first axis; and fifth means for varying the angular circumferential position of said sprayers about said first axis, whereby said sprayers may be positioned so as to paint the entire interior of said vehicle, wherein said second means comprises a fixed support; said fifth means comprises a cradle mounted on said fixed support for rotation about said first axis; said fourth means comprise a box beam pivotally mounted on said cradle about a third axis transverse to said first and second axes, and means for controlling the angular position of said box beam about said third axis; wherein said third means comprise a cross piece mounted parallel to said third axis on an end of said box beam opposite said cradle, two arms, one end of each said arm pivotally mounted on each end of said cross piece about parallel fourth axes, said arms extending in a common plane and said sprayers mounted on the other end of each said arm, and servomotor means for pivoting each said arm about a respective fourth axis, and wherein said cross piece is rotatable about a fifth axis parallel to the length of said cross piece, said apparatus including an articulated link pivoted between said cradle and said cross piece, wherein said common plane is always parallel to said first axis.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 including: an enclosure housing said apparatus; sixth means for moving said vehicle onto, and off of said first means; and control means for controlling the operation of said first through sixth means.
Claim 4
Independent Claim
100 words
An apparatus for painting the interiors of vehicle body enclosures, comprising: first means for supporting a vehicle and moving said vehicle along a first axis; an electrostatic paint sprayer; second means for supporting said sprayer; third means operable on said second means for moving said sprayer in a direction transverse to said first axis between a first position coincident with said first axis and a second position spaced from said first axis and lateral to the sides of said vehicle; and fourth means operable on said second means for moving said sprayer in a direction parallel to said first axis.
Claim 5
Independent Claim
100 words
An apparatus for painting the interiors of vehicle body enclosures, comprising: first means for supporting a vehicle and moving said vehicle along a first axis; an electrostatic paint sprayer; second means for supporting said sprayer; third means operable on said second means for moving said sprayer in a direction transverse to said first axis between a first position coincident with said first axis and a second position spaced from said first axis and lateral to the sides of said vehicle; and fourth means operable on said second means for moving said sprayer in a direction parallel to said first axis.
Claim 6
Dependent Claim
52 words
The apparatus of claim 3 wherein said second means includes a first portion positioned lateral to said sides of said vehicle and having a second axis parallel to said first axis, and wherein said first portion is rotatable about said second axis to move said sprayer between said first and second positions.
