Definitions

  • the invention also relates to a method for treating workpieces, in particular for coating and / or drying vehicle bodies, comprising guiding workpieces through a treatment room by means of a conveyor system which comprises a plurality of transport trolleys, each transport trolley having a chassis and a fastening device for at least comprises a workpiece, which are coupled to one another by means of a connecting device, and wherein outside the treatment room there is a guide area with a driving area for the chassis, which is connected to the treatment room via a connecting passage in such a way that the chassis of a transport vehicle is movable in the driving area and while the fastening device is carried along in the treatment room and the connecting device extends through the connecting passage.
  • treatment devices can be present, in particular in the form of coating booths or dryers.
  • coating booths the workpieces are provided with a coating and, for example, painted; the treatment room in this case is a coating tunnel or a painting tunnel.
  • the treatment room is accordingly a drying tunnel.
  • Treatment devices can also be present in the form of assembly devices and / or control devices in which the workpieces are assembled or assembly work is carried out on the workpieces or in which the workpieces are checked during the ongoing production process.
  • connection passage can cause the atmosphere of the treatment room to pass into the driving area.
  • this atmosphere is polluted with solvents, which can then condense out in the usually cooler driving area and be reflected on the components of the conveyor technology in the driving area.
  • the DE 20 2017 106 843 U1 proposes in a treatment system and a method of the type mentioned at the outset to supply a gas to the driving area so that gas always flows from the driving area into the treatment tunnel and not vice versa.
  • this has the considerable disadvantage that in this way impurities are brought into the treatment tunnel from the driving area.
  • contamination is in particular abrasion or lubricants of the components of the conveyor system in the driving area.
  • the DE 20 2017 106 843 U1 also suggests that the driving area has its own housing and that a gas is supplied to it under overpressure. But even then, relatively large volumes of gas have to be moved.
  • locks must be provided at the ends of the driving area in order to maintain the pressure in the driving area even when the trolleys are moving in and out; however, these locks are expensive to build simply because of the necessary cross-section of the driving space.
  • the gas device is set up in such a way that the gas flowing through flows through the driving space with a directional component transverse to a direction of movement of the trolleys.
  • the gas device is set up in such a way that the gas flowing through flows through the driving space with a directional component parallel to a direction of movement of the trolleys. This corresponds to an inclined flow guidance in relation to the direction of movement of the trolleys.
  • the driving compartment housing has one or more gas inlet openings and one or more gas outlet openings. In each case, several inlets and outlets are favorable, so that the flow gas can flow through the driving area in a targeted and controllable manner.
  • the gas device is preferably set up in such a way that the volume flow Q [m 3 s -1 ] of the supplied through-flow gas can be set at one or more gas inlet openings and / or that the volume flow Q [m 3 s -1 ] of the exhaust gas discharged at one or more several gas outlet openings is adjustable.
  • a conditioning device is present to which the exhaust gas can be fed, wherein the conditioned gas can be fed to a fresh air supply for the treatment device.
  • the object specified above is achieved in that the driving space is defined by a driving space housing; a gas device is present which is set up in such a way that a flow-through gas, in particular air, is fed to the driving area and at least a large part of the flow-through gas is discharged from the driving area as exhaust gas without this flow-through gas reaching the treatment room through the connecting passage.
  • a flow-through gas in particular air
  • the flow-through gas flows through the driving space with a directional component parallel to a direction of movement of the trolleys.
  • the driving space housing preferably has one or more gas inlet openings and one or more gas outlet openings.
  • the volume flow Q [m 3 s -1 ] of the supplied through-flow gas can be set at one or more gas inlet openings (92) and / or the volume flow Q [m 3 s -1 ] of the exhaust gas discharged can be set at one or more gas outlet openings (94 ) can be set.
  • exhaust gas is fed to a conditioning device and the conditioned gas is fed to a fresh air supply for the treatment device.
  • Ambient air from the vicinity of the treatment device is used as the gas flowing through. Since the gas flowing through cannot get into the treatment room, or only to a small extent, this ambient air does not have to be cleaned or otherwise processed.

  • the fastening device 56 in the present exemplary embodiment comprises a support profile 58 with bearing bolts 60, which cooperate in a manner known per se with counter elements on the vehicle body 14 so that the vehicle body 14 can be fixed on the fastening device 56 .
  • the fastening device 56 can also have several sets of such bearing bolts 60, which are adapted to different vehicle bodies 14 with different dimensions and configurations, so that the fastening device 56 can be used flexibly for different vehicle body types.

  • Both the precursor unit 66 and the follower unit 68 can each be connected to a strut 64 or to a joint strut.
  • the treatment device 16 and the conveyor system 34 are coordinated with one another in such a way that only part of the conveyor system 34 moves in the treatment room 20, ie in the treatment tunnel 22, while the other part of the conveyor system 34 is moved outside the treatment room 20.
