Abstract
The invention relates to a device for the surface treatment of workpieces (12) such as vehicle bodies. One such device has a plurality of successive treatment stations (1-9), a guiding system (16, 17) having a first guiding section (16) extending in the region of the treatment stations (1-9), and a plurality of rotational mounts (13) which can move individually on said guiding system (16, 17). Each rotational mount (13) has a holding device (14) for at least one workpiece (12) and a rotational axis (15) which is arranged in such a way that the workpeice (12) in the holding device (14) can be brought into, or taken out of, one of the treatment stations (1-9) by rotation about the rotational axis (15).
Claims15
System for the surface treatment of workpieces (12), such as vehicle bodies, comprising:
- a plurality of successive treatment stations (1 to 9),
- a guiding system having a first guiding section (16) disposed in the region of the treatment stations (1 to 9), and
- a plurality of rotational mounts (13) which can move individually on the guiding system (16, 17), each of which is provided with a holding device (14) for at least one workpiece (12) and which has a rotational axis (15) which is arranged such that the workpiece (12) can be brought into one of the treatment stations (1 to 9) and moved out of it by turning about the rotational axis (15).
System according to any one of the preceding claims, characterized in that the guiding system has a second guiding section (17) which forms a closed loop with the first guiding section (16).
System according to any one of the preceding claims, characterized in that the guiding system is formed as a rail (16, 17).
System according to any one of the preceding claims, characterized in that each rotational mount (13) has a lever arm coupled with the rotational axis (15) which interacts with the stationary lever guidance such that the rotary motion is effected by a longitudinal travel of the rotational mount (13) in the guiding system (16, 17).
System according to any one of the preceding claims, characterized in that a feeding device, by which the workpieces (12) may be mounted on a rotational mount (13), and a take-up device are present, by which the treated workpieces (12) may be taken out from the rotational mounts (13).
System according to any one of the preceding claims, characterized in that the second guiding section (17) of the guiding system for returning the rotational mounts (13) runs from an output region to an input region of the system above, below or laterally to the treatment stations (1 to 9).
System according to any one of the preceding claims, characterized in that the rotational axes (15) of the rotational mounts (13) are arranged in parallel or vertically to the travel direction of the rotational mounts (13).
System according to any one of the preceding claims, characterized in that the rotational mounts (13) are equipped with a power accumulator which stores the energy required for driving the rotational mounts (13).
Method for the surface treatment of workpieces (12) such as vehicle bodies, wherein moveable rotational mounts (13) each having one holding device (14) for at least one workpiece (12) and a rotational axis (15) are independently of each other moved to a desired position on a plurality of successive treatment stations (1 to 9), and wherein the at least one workpiece (12) is brought into a treatment station (1 to 9) or moved out of it by turning a rotational mount (13) about the rotational axis (15) during the movement or after standstill of the rotational mount (13).
