Definitions

  • the invention relates to a coating installation for coating components with a coating agent, in particular in the form of a painting installation for painting motor vehicle body components with a paint.
  • pneumatically driven paint supply pumps which are arranged in a paint supply space of the paint shop, are often used to convey the paint to be applied.
  • the drive of these paint supply pumps by means of compressed air, which is then discharged via an exhaust port of the ink supply pump.
  • One way of removing the exhaust air from the paint supply pumps is to deliver them via a silencer in the immediate ambient air.
  • Another way of removing the exhaust air from the paint supply pumps is to collect them via air ducts in the paint supply room and then to lead into the open. In both cases, however, the exhaust air of the pneumatically driven ink supply pumps is not used.
  • the invention is therefore based on the object to provide a correspondingly improved coating system.
  • the invention is based on the technical-physical knowledge that the exhaust air of the pneumatically driven ink supply pumps is relaxed and cools due to the expansion.
  • the cold exhaust air flow of the pneumatically driven pumps can therefore be used for cooling purposes.
  • the invention therefore provides a cooling device which cools a heating sensitive component (e.g., railhouse) of the coating equipment by means of the cold exhaust air flow of the pump.
  • a heating sensitive component e.g., railhouse
  • the cooling device has at least one first heat exchanger in order to transfer heat from the heating-sensitive component (eg paint line, railhouse) of the coating system to the cold exhaust air flow of the pump, whereby the heating-sensitive component of the coating system is cooled.
  • the heating-sensitive component eg paint line, railhouse
  • a plurality of heat exchangers are connected in series.
  • the first heat exchanger is an air / air heat exchanger, ie both the heat supply to the hot side of the heat exchanger and the heat removal on the cold side of the heat exchanger via an air flow.
  • the first heat exchanger is an air / water heat exchanger, d. H.
  • an air flow is passed through the heat exchanger, namely the cold exhaust air flow of the pump, whereas on the hot side of the heat exchanger, a water flow is passed through the heat exchanger.
  • the heat exchanger is preferably a recuperator, i. a heat exchanger with an indirect heat transfer between cold side and hot side and a material separation between cold side and hot side.
  • the cooling device has a cooling circuit, which connects the heating-sensitive component of the coating system with the first heat exchanger, the cooling circuit containing a cooling medium (eg air, water) to the dissipated heat from the heating-sensitive component of the coating system to the first heat exchanger to transport.
  • a cooling medium eg air, water
  • the cooling medium is preferably conveyed in the cooling circuit by a pump in circulation operation.
  • the heating-sensitive component of the coating installation can be, for example, a pipeline, for example a coating medium line or a paint guide line.
  • a pipeline for example a coating medium line or a paint guide line.
  • Such pipelines are known from conventional coating systems or paint shops and therefore need not be described in detail.
  • the cooling circuit is connected via a second heat exchanger with the respective coating medium line, wherein the second heat exchanger transfers the dissipated heat from the coating medium line to the cooling circuit, from where the dissipated heat from the first heat exchanger to the cold exhaust air flow of the pump is transmitted.
  • the warming-sensitive component of the coating system is a so-called “railhouse”, ie a protective housing which surrounds a travel axis of a robot (eg painting robot, handling robot).
  • a robot eg painting robot, handling robot.
  • Such "rail houses” are for example in DE 102 34 915 A1 described and also belong to the general expertise, so that in this respect can be dispensed with a detailed description.
  • the cooling circuit introduces cold air into the protective housing ("railhouse”) and removes warm air from the protective housing ("railhouse”) in order to lower the internal temperature of the protective housing ("railhouse”).
  • the cooling of the compressed air used to drive the pump can lead to the formation of condensation or ice formation (icing) on the components of the system which come into contact with the relaxed, cold exhaust air from the pump.
  • the connected to the exhaust port of the pump cold air line is therefore provided on its outside with a thermal insulation to avoid condensation or ice formation on the outside of the cold air line.
  • the inventive idea of thermal insulation of the cold air line is independent of a cooling device of its own worthy of protection.
  • the coating installation according to the invention preferably has a plurality of pneumatically driven pumps each having an exhaust air connection, the exhaust air connections of the pumps opening into a common cold air duct, which is preferably connected to the first heat exchanger.
  • the pneumatic pump may be designed as a piston pump or as a diaphragm pump, however, the invention is not limited to these designs of the pump.
  • pneumatically driven pumps are preferably arranged in a paint mixing chamber of the coating installation, which is known per se from the prior art and therefore need not be described in detail.
  • the heating-sensitive component of the coating installation can be, for example, a pipeline or a so-called "railhouse".
  • Another example of the warming-sensitive component of the coating system is a paint booth.
  • the interior of a paint booth usually has to be air-conditioned, so that the painting within the spray booth under constant climatic conditions takes place, which is important for an optimal painting result.
  • the cold exhaust air of the pneumatically driven pump can therefore also be used for cooling or air conditioning of the paint shop, which can significantly reduce the energy required for air conditioning of the paint booth. This is of particular importance because the energy consumption of a paint shop makes up a large proportion of the total energy consumption of a motor vehicle factory.
  • FIG. 1 shows a first embodiment of a painting according to the invention for painting of motor vehicle body components
  • the paint shop largely conventional is constructed so that can be dispensed with a detailed description of the structure and operation of the paint shop and in the following only the essential parts of the painting are described.
  • the paint shop has several colored lines 1-5, in which paints of different colors are circulating promoted to prevent settling of the paints in the loops 1-5.
  • the color guide lines 1-5 extend in each case through heat exchangers 6-10, which can be designed, for example, as a tube-in-tube heat exchanger and have the task of cooling the lacquer in the individual color guide lines 1-5.
  • the heat exchangers 6-10 are connected to a common cooling circuit 11, which contains water as a cooling medium, wherein the cooling water is conveyed in the cooling circuit 11 by a pump 12 in circulation operation.
  • the cooling circuit 11 extends through a further heat exchanger 13, wherein it is an air / water heat exchanger.
  • a cold air line 14 passes through the heat exchanger 13, wherein the cold air line 14 is supplied by exhaust air ports 15-21 of several pneumatically driven ink supply pumps 22-28 with cold air.
  • the paint supply pumps 22-28 can be designed conventionally as a diaphragm pump or as a piston pump, so that a detailed description of the ink supply pumps 22-28 can be dispensed with.
  • the ink supply pumps 22-28 are preferably arranged in a paint mixing room of the paint shop.
  • the compressed air supplied via the supply air connections 29-35 compressed air is relaxed and thereby cooled, so that is discharged via the exhaust ports 15-21 cold air into the cold air line 14.
  • the cold air then absorbs heat from the cooling water in the cooling circuit 11, whereby the temperature of the cooling water in the cooling circuit 11 is reduced.
  • the heat exchangers 6-10 then transfer heat from the paint in the color guide lines 1-5 to the cooling water in the cooling circuit 11, thereby cooling the paint in the color guide lines 1-5.
  • FIG. 2 shows a modification of the embodiment described above according to FIG. 1
  • FIG. 2 shows a modification of the embodiment described above according to FIG. 1
  • a special feature of this exemplary embodiment is that in this case a so-called railhouse 36 is cooled, ie a protective housing which surrounds a traveling axis of a robot (painting robot or handling robot) of the painting installation.
  • cooling medium in the cooling circuit 11 is air, so that can be dispensed with the additional heat exchanger 6-10 in the embodiment of Figure 1.
  • the circulating in the cooling circuit 11 cold air is introduced into the railhouse 36 and thereby heated.
  • the heated air is then returned to the cooling circuit 11 and cooled down again in the heat exchanger 13.
  • FIG. 3 a simplified cross-sectional view through the cold air line 14, which is provided on its outside with a heat insulation 37.
  • the thermal insulation 37 should achieve that the outside temperature on the lateral surface of the heat insulation 37 despite the low temperature of the cold air in the cold air line 14 is sufficiently large to prevent disturbing condensation or ice formation on the lateral surface of the heat insulation 37.
