Definitions

  • the invention is directed to a pretreatment plant for spray pretreatment to be coated in a downstream coating plant Objects, each with a plurality of such items and holding device arranged on a transport device is and cyclically successively a plurality of the transport device of spray pre-treatment devices with drip pans for the Treatment medium is supplied, the drip pans immediately are arranged adjacent to each other, and wherein in the area of Edges between two trays one with release of the transport path is provided from this movable separating device.
  • Such a pretreatment plant is described in EP 0 505 694.
  • Winding shafts are with the opposite end portion connected to the separating elements and in turn in the area of the ceiling over Cables stored. The ends of the winding shafts are each on a horizontal Carrier rotatably arranged, with each two horizontal Carrier are guided on a holding device on both sides and by means of a Cable and an associated motor can be raised and lowered.
  • spray nozzles are arranged in the area of each tub, which at a rectangular, annularly closed line are formed, wherein each line has a central inflow.
  • the ring lines are about provided outside of the respective tub bearings on holding devices by means of motor drives in the vertical direction, so that the objects to be treated are viewed in the vertical direction from sprinkled on all sides and spray shadows are avoided in this way.
  • the originally intended foil-like separating elements can at some applications have the disadvantage that during winding the two sides of the film come into contact with each other, so that it for example in the separation of acidic versus basic baths for reactions, ie e.g. salt formation, comes, so that form deposits and functionality is impaired.
  • the invention is based on the object, a plant the type in question even more compact, simpler and cheaper build.
  • a spray nozzle assembly is integrated, which together with the Separating elements can be raised and lowered, the spray nozzles on Both sides of the separating elements are arranged when the separating elements not edge-sided, but arranged between two adjacent tubs are.
  • the spray nozzles on the height and Width of the dividers are largely evenly distributed to this way to ensure the most uniform possible spraying.
  • the spray nozzles can during the spraying - as conventionally the case is still moving up and down with a small amplitude become.
  • the separating elements are made of a Plurality of horizontally extending, accordion-like over joints formed slats.
  • a coating e.g. be provided with a plastic film, which on the one hand the lines for the spray nozzles and.die spray nozzles and at the same time also the articulated connection between produces the slats.
  • a pretreatment plant shown in the drawing comprises a Plurality of drip pans 1, wherein in the drawing of simplicity half only four tubs 1a to 1d are shown, although for most In practical applications, several such trays, e.g. seven such Tubs are provided.
  • a first tubs for pickling degreasing by means of a slightly alkaline solution, a second bath for rinsing with water, a third tray for decanting (neutralizing) for weak, e.g. 10% sulfuric acid, a fourth sink to rinse, a fifth pan to chromate with weak chromic acid, a sixth pan to Rinse with demineralized water and a seventh bath for rinsing be provided.
  • Rails 4 includes, on which motorized cyclically driven carrier. 5 run, on which also only schematically indicated holding devices 6 attached to the hanging, to be treated objects 7 are.
  • the transport device 3 transports the holding devices 6 in the direction of the arrow 8 in Fig. 1 intermittently such that the holding devices. 6 each above a tub 1 for the duration of a later to be described Spray treatment remain, then each one again further transport step, e.g. from the tub 1a to the tub 1b, further transported to become.
  • support rods 18 are concertina foldable separators 15 arranged, which are formed for example by a film, which bent under formation of fold lines and with a Weld is provided, it may also be provided that the Welds form a kind of hemstitch, in each of which a metal rod is inserted, so that due to the weight of these rods the automatic folding when lowering the support rods 19 favors becomes. Moreover, it can be provided that the individual slats have a bore through which a kind of guide thread is guided.
  • the separating elements 15 formed as films, again holding rods 18 to achieve a defined folding are provided. Also here are at the Separator 15 ring lines 10 with spray nozzles 11 over the height arranged distributed.
  • the transport device 3 can now have a further cyclic transport step cause.
