Definitions

  • the invention relates to a device of the type specified in the preamble of the first claim.
  • the object of the present invention is to remedy this situation and to design a device of the type mentioned at the outset such that adequate drying of the coated objects can be carried out with little space and time required even when using hard-to-evaporate solvents.
  • This object is achieved according to the invention by the characterizing features of the first claim.
  • the arrangement according to the invention creates a blowing tunnel, in which it is ensured in the first zone by the radiators that sufficient evaporation of the solvent is achieved and by the inflowing air that the removal of solvent is ensured.
  • the body surface is recooled to temperature values which enable the body to be further treated by additional painting processes without any loss of quality.
  • Infrared emitters have proven to be particularly suitable emitters. It is known to use infrared drying for accelerated film formation in painted workpieces. However, their use in large series systems has not previously been considered possible because the emitters feared that the painted workpieces would be heated up too much and therefore an increased space requirement and / or time required for the necessary cooling before the next processing steps was expected.
  • blow tunnel constructed in accordance with the invention is shown schematically in perspective.
  • the blow tunnel 1 consists of a first zone 2 and a second zone 3. These two zones 2, 3 represent the core zones of the blow tunnel.
  • an inlet area known per se can also be provided in the direction of flow in front of zone 2 and an outlet area adjoining zone 3.
  • a conveyor 4 is provided on the bottom of the blow tunnel 1 for transporting the workpieces, in particular the motor vehicle bodies.
  • Such conveyors are generally known and are therefore - since they do not fall under the subject of the invention - not described in detail.
  • the blowing tunnel 1 preferably has an octagonal cross section to ensure that all painted surfaces of the motor vehicle bodies can be dried uniformly and sufficiently quickly.
  • infrared emitters 5 and blowing nozzles 6 are alternately offset in zone 2 in the opposite wall areas and in the ceiling area.
  • the blowing nozzles 6 are connected to a known, not shown supply air delivery system.
  • the air emerging from the blowing nozzles can be tempered, depending on the requirements. Temperature ranges between 23 ° C and 70 ° C are preferred.
  • the infrared radiators 5 can be regulated and therefore emit a variable power.
  • Zone 2 it can make sense to divide Zone 2 into two sections of the same structure and to connect the blowing nozzles of the two sections to separate air delivery systems in order to achieve different blowing air temperatures and quantities and different levels of humidity in Zone 2.
  • Zone 3 connects seamlessly to Zone 2. This consists only of a plurality of blowing nozzles 6. This zone 3 serves to cool the heated motor vehicle body. This is therefore necessary in the subsequent processing step, e.g. B. when applying a clear coat to get a cheap, low sheet temperature.
  • the blow nozzles 6 provided there are therefore connected to a further air guidance system in order to obtain the necessary cold air. Air temperatures of approximately 10 ° C. to 23 ° C. are preferred.
