Definitions

  • the invention relates to a device for tempering vehicle bodies according to the preamble of patent claim 1.
  • the term "tempering" of a vehicle body refers to the bringing about of a specific temperature of the vehicle body which it does not initially possess. It may be a temperature increase or a temperature decrease.
  • a "tempered air” is understood to mean that which has the temperature required for temperature control of the vehicle body.
  • the following description of the invention in detail is based on the example of such a dryer.
  • drying refers to all processes in which the coating, in particular a lacquer, of the vehicle body can be cured, be this by expelling solvent or by crosslinking the coating substance.
  • dryer designed devices of the type mentioned usually have both sides of the tempering tunnels designated in this case as drying tunnels a pressure chamber.
  • the nozzles which are housed in the walls separating the pressure chambers from the drying tunnel have different and often unadjusted distances from the areas of the vehicle body which they are to apply to them.
  • vehicle bodies have different masses in different areas; In particular, the lowest area, the threshold area or the floor area, is heavily massed. Accordingly, the heat capacities in the different vehicle body areas are also different and the times necessary to bring these areas to the temperature required for drying also differ.
  • the residence time of the vehicle body to be dried in the dryer must therefore be adapted to the longest time that the worst, most massively afflicted area of the vehicle body needs to dry.
  • a device of the type mentioned is, for example, from the US 2009/0017408 A1 known. There, in addition to heated air and radiant heat is still used for drying by the hot air, before it is directed through nozzles on the body to be dried, through cavities, which in turn then emit radiant heat.
  • Object of the present invention is to provide a device of the type mentioned in such a way that certain work, such as cleaning and maintenance, are easily possible on the device or the transport system and a conversion of the device.
  • the different areas must be subjected to different intensities of tempered air to a uniform temperature of the vehicle body in order to take into account the different local heat capacities.
  • the lower portion of the vehicle body, the sill area or the floor group requires special treatment with tempered air.
  • This is done with a special nozzle device, which is brought to one side particularly close to this lower region of the vehicle body and, in order to comply with the smallest possible distances, is also adapted in geometry to the geometry of the lower vehicle body area.
  • the massive lower region of the vehicle body comes to the desired temperature at about the same time as the higher-lying, less massive regions.
  • the temperature of the vehicle body is done overall faster and without unduly high or low local temperatures, which could damage the materials of the vehicle body. moreover This is an energy saving when used as a dryer connected, as with lower temperatures of the hot air could be worked.
  • the nozzle device is releasably attached to at least one opening in the wall between the pressure chamber and the tempering tunnel. It can be quickly removed if necessary. This is important because it extends relatively far into the tempering tunnel and could be in certain work such as cleaning and maintenance, and also on the transport system, outside of the actual tempering in the way.
  • the at least one opening to which the nozzle means is fixed is designed in the same way as the openings in which the other nozzles are fixed in the same wall.
  • the nozzle device can be retrofitted by removing one or more of the normal nozzles in the lower region of the wall between the pressure chamber and tempering tunnel in a conventional device and instead fixing the nozzle device according to the invention to this or these openings.
  • a retrofitting of an inventively designed device in a conventional device easily possible.
  • the nozzle device surrounds the vehicle body below, so is not only guided along the side surface of the lower vehicle body portion but formed down around the lower portion and still extends a certain distance under the vehicle body. Undercuts in the geometry of the nozzle body are possible.
  • the distance between the vehicle body facing side of the nozzle device and the vehicle body is suitably about 20 cm. At this distance, a good and fast tempering result is achieved with conventional materials, but without damaging these materials. In specially directed against the bottom of the vehicle body nozzles, the Absrand can also be smaller, in particular about 10 cm.
  • the nozzle body can be exchangeable. In this way, the device can be easily adapted to different vehicle bodies with different geometries in the lower area.
  • a dryer is schematically and collectively designated by the reference numeral 1, which serves as an example of a tempering. It comprises in a known manner a housing 2 whose interior is divided by two longitudinally extending walls 3, 4 in two lateral pressure chambers 5, 6 and a lying in the middle as a drying tunnel tempering 7.
  • a conveyor system 8 extends through the drying tunnel 7 and conveys the freshly coated vehicle bodies 9 to be dried, perpendicular to the drawing plane, through the drying tunnel 7.
  • At the inlet and at the outlet of the drying tunnel 7 are located in a known manner an inlet or an outlet lock, which are not shown and need not be described in detail.
  • nozzles 10, 11 are provided, which connect the pressure chambers 5, 6 with the drying tunnel 7.
  • These nozzles 10, 11 have conventional construction and need not be described in detail. They are called “normal” nozzles here. It is sufficient to know that the orientation of its axis within the walls 3, 4 is adjustable as needed.
  • nozzle devices 12, 13 are arranged, which also connect the pressure chambers 6 with the drying tunnel 7 and whose construction is now explained in more detail with reference to the nozzle device 12.
  • the nozzle device 13 basically has the same structure.
  • the nozzle device 12 has a middle, obliquely against both the vertical and the horizontal hired nozzle body 14, in which the vehicle body 9 side facing a plurality of individual nozzle openings 15 is provided.
  • This side of the nozzle body 14 is adapted at least approximately to the sill area 16 of the vehicle body 9 and engages around this sill area 16 below, where even an undercut can be seen.
  • the two opposite ends of the nozzle body 14 are approximately in the installed position horizontally extending connection channels 17, 18 connected to openings 19, 20 in the wall 3, which serve in conventional dryers receiving normal nozzles 10 and have for this purpose kugelkalottenförmige side surfaces.
  • the ends of the connection channels 17, 18 are each provided with spherical cap-shaped clamping plates 21, 22. In this way, the entire nozzle device 12 can be clamped by inserting the clamping plates 21, 22 in the openings 19, 20 on the wall 3.
  • the vehicle bodies 9 are located on their transport through the drying tunnel 7 by means of the conveyor system 8 on skids 23, as is well known in itself and have two running parallel to the direction of skids 24, 25. At these runners 24, 25, the transport system 8 is used for locomotion of the vehicle body connected to the skid 22. They are protected by a shielding plate 40 against the direct application of hot air.
  • the two pressure chambers 5, 6 are connected in known manner with a source of hot pressurized air; generally located in the lower part of the drying tunnel 7 are not shown suction, through which the air can be removed from the drying tunnel 7 again.
  • the dryer 1 is operated in recirculation mode; This means that the air extracted from the drying tunnel 7, cleaned and then reheated, is recirculated to the pressure chambers 5, 6 by means of a ventilator.
  • the vehicle bodies 9 are subjected to either continuous movement or at standstill via the normal nozzles 10, 11 in the lateral and upper regions with hot air. This will be dried the relatively less mass-containing lateral and upper portions of the vehicle body 9.
  • the hot air coming from the pressure chambers 5, 6 is relatively close to the surface of the vehicle body 9 by means of the nozzle devices 12, 13. in particular of the sill area 12, introduced, which is applied in this way there particularly intense hot air.
  • a favorable distance is about 20 cm, for the body floor acting nozzle openings 15 also only 10 cm. Due to the proximity between the nozzle openings 15 of the nozzle devices 12, 13 and the corresponding surface regions of the vehicle bodies 9, it is also possible to sufficiently heat the massive subregion of the vehicle body 9 in a time for drying which corresponds approximately to the time within which the normal nozzles 10 , 11 are capable of drying the upper portion of the vehicle body 9. In this way, the cycle times during drying of the vehicle body 9 can be reduced and overheating, which could not be excluded in the conventional dryer in the upper region of the vehicle body 9, avoided.
  • FIG. 3 is in a sectional view, which is the FIG. 2 corresponds, a variant of a dryer 101 shown in fragmentary form.
  • Corresponding parts in FIG. 3 are denoted by the same reference numerals as in FIG. 2 , but increased by 100, marked.
  • Recognition in FIG. 3 are the longitudinal wall 103, which separates the pressure chamber 105 from the drying tunnel 107, and a normal nozzle 110.
  • This nozzle 110 is located in an opening 119 of the wall 103, which in the embodiment of figure 2 the inclusion of a connection channel 17 of the nozzle device 12 has served.
  • FIG. 3 is in a sectional view, which is the FIG. 2 corresponds, a variant of a dryer 101 shown in fragmentary form.
  • Corresponding parts in FIG. 3 are denoted by the same reference numerals as in FIG. 2 , but increased by 100, marked.
  • Recognition in FIG. 3 are the longitudinal wall 103, which separates the pressure chamber 105 from the drying tunnel 107, and a normal
  • the nozzle device 112 has only one connection channel 118, at the ends of which two clamping plates 121, 122 are found, which are clamped in the opening 120 of the wall 103. Also, the nozzle body 114 of the nozzle device 112 has in the vehicle body 109 side facing a plurality of nozzle openings 115; this page is adapted in its contour of the contour of the sill area 116 of the body 109 to be dried.
  • the embodiment of the nozzle device 112, which in FIG. 3 is slightly cheaper than that of the FIG. 2 and is mainly used where the need for hot air to dry the sill area 116 of the vehicle body 109 is not so great.
