Definitions

  • the invention relates to a coating system for workpieces, in particular for vehicle bodies, comprising a coating application section, a subsequent coating dryer section comprising a dryer cabin arranged higher than the coating application section, a skid conveyor on the input side passing through the coating application section, with which workpieces mounted on skid frames are passed through the coating application section at a process feed rate can be moved through to apply the coating, and a dryer conveyor which runs below a skid frame path and conveys the skid frame with the coated workpieces mounted thereon along the skid frame path at the process feed rate through the dryer cabin.
  • the dryer conveyor device is designed such that it has a lifting device which lifts the skid frames coming from the input-side skid conveyor so that they can then pass through the dryer cabin.
  • a dryer conveyor is provided in the dryer cabin, which conveys the skid frames with the workpieces mounted thereon at the process feed speed through the dryer cabin. After completion of the passage through the coating dryer section, the skid frames are lowered again by a lifting device.
  • Such a coating system is complex to design, since acceleration sections are required to load the lifting device in order to separate between the skid frames successively conveyed by the skid conveyor at a process feed speed and to gain the necessary time for the lifting process.
  • the invention is based on the object of improving a coating system of the generic type in such a way that it is constructed more simply than the known coating systems.
  • the coating system according to the invention is structurally simpler and therefore less susceptible to failure.
  • the configuration of the coating system according to the invention is particularly suitable when the coating system comprises a reworking section adjoining the coating dryer section with a skid conveyor on the output side.
  • a reworking section can include any type of reworking, but also, for example, the simple further transport of the skid frames to a subsequent processing station, which does not result in any coating process or work involved, but the further assembly of a vehicle.
  • the dryer conveyor conveys the skid frames in an end region of the coating dryer section over an inclined plane downwards to a skid conveyor on the output side.
  • skid frame used in connection with the solution according to the invention encompasses all transport devices for the workpiece which have at least two skid runners which are arranged at a distance from one another transversely to the transport direction, in particular rigidly connected to one another. These are connected to one another, for example, by at least two transverse struts and are kept at a distance from one another.
  • the skid runners directly on the workpiece, for example on a vehicle body, so that the workpiece itself takes over the connection of the skid runners to one another.
  • Such a skid frame is preferably conveyed on skid conveyors which have two sets of rollers for the skid runners which are arranged at a distance from one another and between them a drive, for example a clock drive for feeding the skid frames at the process feed speed, which ensures stable and wobble-free transport of the mounted on the skid frame Ensure workpiece, in particular also for position-sensitive machining processes, such as the application of a coating.
  • skid conveyors which have two sets of rollers for the skid runners which are arranged at a distance from one another and between them a drive, for example a clock drive for feeding the skid frames at the process feed speed, which ensures stable and wobble-free transport of the mounted on the skid frame Ensure workpiece, in particular also for position-sensitive machining processes, such as the application of a coating.
  • skid frames in the area of the dryer conveyor are guided along the skid frame track with their skid runners free of skid guide tracks.
  • This has the great advantage that with regard to the skid frame track, along which the skid frame is transported with the dryer conveyor, there is no need to take into account the conditions of a skid conveyor and the conditions given by running the skid runners on sets of rollers.
  • the skid frames can be moved on narrower arc radii than would be the case with skid conveyors, which generally only allow movement of the skid frames in one direction or with slight deviations from this direction.
  • the skid conveyor brings the skid frame into a transfer station and the dryer conveyor picks up the skid frames in the transfer station and thus preferably transports them free of the usual runner tracks from this transfer station.
  • the dryer conveyor in the transfer station approaches and takes up the respective skid frame from below with a skid frame pickup, so that especially after the transfer station the skid frame is complete is carried by the dryer conveyor.
  • skid frame pickup With regard to the inclusion of the skid frames by the skid frame pickup, no further details have so far been given.
  • the skid frame receiver supports the skid frame in each case at two points spaced apart from one another in the conveying direction, each with a support element. This ensures, in particular, a secure receptacle against tipping about an axis running transversely to the conveying direction.
  • the skid frame pickup With regard to the support of the skid frame by the skid frame pickup, it would be possible, for example in an advantageous embodiment, for the skid frame pickup to support the skid frame on a cross brace thereof in the area between the skid runners. Still It would be more advantageous if the skid frame receiver supports the skid frame on two cross struts of the skid frame which are arranged at a distance from one another in the conveying direction.
  • skid frame pickup supports the skid frame on its skid runners, since this provides a broad and therefore secure support of the skid frame itself, which thus has a quality that matches the quality of the support in the skid conveyor itself corresponds.
  • Such support of the skid frame by the dryer conveyor can be realized particularly simply in that the dryer conveyor supports the skid frame with its two support elements, the support elements each having support surfaces for the respective skid frame.
  • the support elements have guide surfaces on which, for example, the skid runners rest and are thereby secured against displacement transversely to the conveying direction.
  • the carriages are preferably guided in the guide rails with two pairs of supporting rollers arranged at a distance from one another, so that safe and reliable guidance of the carriages, which prevents them from tilting relative to the guide rails, is provided.
  • a preferred embodiment provides that the support elements each sit on their own carriages and that the carriages are connected to one another in particular in the simplest case via a conveyor run.
  • the conveyor run is formed by a chain, the links of which can preferably be moved relative to one another only about an axis, so that this exemplary embodiment of the conveyor chain only allows the same to be guided in arches lying in one plane.
  • This is preferably a substantially vertical plane, so that the conveyor chain only describes arches in this plane and, on the other hand, has the property of guiding the support elements parallel to one another transversely to the conveying direction, in particular transversely to the vertical plane, so that apart from the connection the conveyor chain requires no further connection between the two support elements.
  • the support element preferably has a support roller.
  • An advantageous exemplary embodiment provides that one of the carriages is rigidly connected to the conveyor strand and the other carriage is freely movable relative to the conveyor strand.
  • the two support elements are preferably arranged on the side member.
  • the longitudinal beam is connected to each of the carriages via at least one joint, in particular if the carriages have two sets of idler rollers arranged at a distance from one another.
  • the two joints are then arranged in such a way that their joint axes are parallel to one another and preferably perpendicular to the plane in which the conveying run is to describe an arc.
  • the carriages are each connected to the longitudinal member via two joints, the two joints pivoting about two perpendicular to one another and transversely to the conveying direction allow extending axes and on the other hand the axes of the two joints between the two carriages and the side member are preferably aligned parallel to each other.
  • the conveyor strand can be any type of element that is suitable for describing an arc in the desired levels.
  • a conveyor chain has proven to be particularly reliable and with sufficient accuracy and simplicity as a funding strand.
  • the conveyor chain is designed in such a way that it has chain links which can be moved relative to one another at least about one axis, this axis being perpendicular to the plane in which the arc to be described by the conveyor chain lies.
  • the embodiment described above is particularly suitable for the conveyor chain to be able to describe an arc in several, for example at least two, levels.
  • the chain links can be pivoted relative to one another about two axes, the two axes each being perpendicular to the planes in which the conveyor chain describes an arc.
  • the two axes about which the chain links can be pivoted relative to one another run parallel to the two axes of the joints between the carriage and the longitudinal member.
  • the chain can also be designed so that it provides an even greater mobility between the individual chain links.
  • Such an embodiment of a dryer conveyor according to the invention makes it possible, for example, to place the conveyor strand in the coating dryer section in a substantially horizontal plane and then also to place the conveyor strand in a horizontal plane in the area of the transfer stations, in particular the conveyor strand between the transfer stations and the coating dryer section is led over an inclined plane.
  • An advantageous embodiment provides that the dryer conveyor engages the respective skid frame with a driver that can be detachably connected to the skid frame.
  • the driver is expediently designed such that it engages on a driver element arranged on the skid frame.
  • the driver element it would be possible to design the driver element as an independent element suitable for the driver.
  • the driving element is formed by a cross strut of the ski frame.
  • An advantageous exemplary embodiment provides that the driver fixes the skid frame against a relative movement in the conveying direction or against the conveying direction.
  • the driver has a driver surface arranged behind the driver element in the conveying direction and a driver surface arranged in front of the driver element in the conveying direction.
  • the driver can be brought into engagement with the driver element in a wide variety of ways.
  • An advantageous exemplary embodiment provides that the driver can be fixed on the driver element by latching.
  • the driver surface is seated on a latch.
  • Such a fixing of the driver on the driver element is particularly advantageous when the front driver surface in the conveying direction is seated on the latch, since in this case there is the possibility of moving in the conveying direction with the driver in the conveying direction by relative movement to the skid frame and thereby doing so to pivot the locking pawl so that the front driver surface can pass the driver element in its pivoted position and then, after pivoting the locking pawl back, can be brought into a position in front of the driver element in which it fixes the driver element.
  • the latch can be operated in a variety of ways. It is particularly advantageous if the latch has a run-up slope with which it can be moved against the driver element itself.
  • the driver can be brought into engagement with the driver element in that the driver from an underside of the driver element can be moved up, in which case the skid frame carrying the driver element and the driver are moved at the same speed and the driver increasingly approaches the driver element from below.
  • a particularly advantageous exemplary embodiment provides that the driver is arranged on a support element.
  • two drivers are provided next to one another at a transverse distance on a support element, which ensure reliable fixing and tilt-free driving of the ski frame.
  • An advantageous exemplary embodiment provides that the conveyor run runs between the guide rails for the carriages.
  • the conveyor run is offset in height from the plane in which the carriages run on the guide rails, that is to say above or below this plane, which has proven to be particularly advantageous if one of the carriages is free relative to the conveyor run movable, that is not rigidly connected to it.
