US 2002/0162504 A1 · Method for introducing and removing workpieces into or from a surface treatment area, a surface treatment device and an arrangement for surface treatment

Abstract

The invention relates to a method for introducing and removing workpieces, especially vehicle bodies, into or from a treatment area (20) by rotational movements, whereby the treatment area serves for treating surfaces of the workpieces (1). A workpiece (1) is detachably fixed at a holding frame (2) which is moved together with at least one workpiece that is situated thereon at an essentially constant speed and by a continuous translation. The workpiece (1) is rotated around a rotational axle (6) at least at the beginning and end of the treatment area (20) and simultaneously with the translation movement. The rotational axle (6) is orientated vertically in relation to the moving direction of the holding frame (2) and is lifted and lowered during rotation.

Method for introducing and removing workpieces, especially vehicle bodies, into or from a treatment area (29), whereby said treatment area serves for treating the surfaces of the workpieces (1) by an introduction operation or a removal operation, wherein

at least one workpiece (1) is detachachably fixed at a holding frame (2),
the holding frame (2) is moved together with the at least one workpiece (1) that is situated thereon at an essentially constant speed and by means of a continuous translation,
the workpiece (1) is rotated around a rotational axle at least at the beginning and the end of the treatment area (20) and simultaneously with the translational movement, with the rotational axle being oriented vertically in relation to the moving direction of the holding frame (2),
characterized in that
the rotational axle (6) is lifted and lowered during rotation.

2 more elements

Apparatus for surface treatment of workpieces (1) in one or a plurality of treatment areas (20), in particular for surface treatment of vehicle bodies in treatment baths or treatment cabins, including

at least a holding frame (2) for picking-up one or a plurality of workpieces (1) which comprises:
a pick-up device by means of which the workpiece (1) is detachably fixable to the holding frame (2), and
a rotational axle (6) around which the holding frame (2) is rotatable,
a holding frame guide device (7) which extends along the one or a plurality of treatment areas (20) and wherein the holding frames (2) are movable in a guided manner,
a rotary device (8, 9, 10) for rotating the holding frame (2) around its rotational axle (6),
a drive mechanism by which the holding frame (2) is movable in the holding frame guide device (7) by means of a continuous translation,
characterized in that
one rotational axle height adjustment (11, 12) each is provided at least in the area of introduction and removal of the treatment area (20), by means of which the rotational axle (6) of a holding frame (2) can be lifted and lowered, and
the rotary device (8, 9, 10) in the area of the rotational axle height adjustment (11, 12) can be activated.
