Unit and method for conveying workpieces along a processing run

Abstract

The invention relates to a unit and method for conveying workpieces along a processing run, comprising at least one transport car (10), moving along the processing run in a conveying direction (FR) and a rotating shaft (20), mounted on the transport car (10), close to a first of the ends thereof, to rotate about the axis thereof at right angles to the conveying direction (FR) and on which a mounting (40) for the workpiece to be processed is provided. The rotating shaft (20) is only mounted close to the first end thereof on the transport car (10) and may thus be driven in the conveying direction (FR), whereupon the second free end thereof is passively transported along in the conveying direction (FR). It is thus possible to pivot the rotating shaft (20) in a plane running at right angles to the conveying direction, in particular, to permit a space saving return.

Description

technical field

[0001] The invention relates to a device for conveying workpieces on a processing line.

[0002] Along such a processing line there is at least one, but mostly a plurality of processing stations arranged one behind the other, into which the workpieces for surface treatment are fed.

[0003] A treatment station can be, for example, an immersion tank with treatment liquid, but the term treatment station can also be understood to mean any other type of chamber or tank in which a workpiece is treated. This treatment can also include, for example, a cleaning process. Further examples for treatments are a dip phosphating, pretreatment for dip painting, powder coating, wet paint coating and similar processes. Background technique

[0004] The hitherto known devices for surface treatment of workpieces, such as motor vehicle bodies, in immersion tanks or treatment chambers are subdivided into continuously conveyed devices and discontinuously conveyed devices. [00...
