Definitions

  • the invention relates to a machine for projecting coating products onto objects, such as, for example, motor vehicle bodies.
  • the industrial production rates and the annual operating plans for the use of the production lines are such that the periods planned for the start-up or maintenance of a coating product application installation are of short duration.
  • the assembly and adjustments of a body-coating installation must generally be completed within three weeks. It is therefore essential to prepare the installation as well as possible before the equipment arrives at the site of operation.
  • the usual technique is to provide, for each projection machine, a control cabinet containing all the control elements specific to the machine in question, in addition to a common cabinet, sometimes referred to as "wiring head cabinet” containing the elements of power and control elements common to all machines in a coating plant.
  • wiring head cabinet containing the elements of power and control elements common to all machines in a coating plant.
  • the invention aims to solve these problems. It relates to a coating product projection machine.
  • This arrangement makes it possible to assemble the machine and the housing and makes it possible to connect all the control elements to all the controlled elements of the projection machine before transporting the machine from the assembly site to the place of use.
  • the place of assembly that is to say generally the production unit of the manufacturer of the machine, is suitable for this type of operation and the staff is sufficient in number.
  • the assembly can be carried out several weeks before transport to the user and it is possible to systematically check all the electrical and fluidic connections.
  • the time of assembly and connection at the place of operation is therefore significantly reduced. Therefore, in a period of the order of three weeks as mentioned above, more time can be spent on fine-tuning the installation under the specific conditions of use.
  • the quality of the coating becomes optimal from the first days of use of the installation.
  • the new arrangement also allows easy maintenance since all the control elements, the controlled elements and the connection elements are accessible by simply opening the doors of the projection machine. Finally, this new arrangement is much more compact and allows significant space savings for the entire installation.
  • FIG. 1 represents a known installation intended for coating objects 1 of relatively large size, such as, for example, motor vehicle bodies, carried by a conveyor 2 moving in the direction of the arrow F.
  • the installation consists of six machines, 3, 4, 5, 6, 7 and 8 called “side machines", divided in equal number on the sides of the path of the objects 1 and each carrying an automatic spray coating product of the pneumatic or rotary type.
  • the installation also includes a machine called "roof machine” 9 for coating the horizontal surfaces of objects 1. This machine 9 carries three sprayers of the same type as those of the side machines.
  • the supply of coating and air products of the machines 3 to 9 is carried out in a manner known per se by bypass connections on paint circulation circuits and on an air supply circuit. She is not represented.
  • the power supply of the entire installation is made from the distribution sector through a so-called "wiring head" cabinet 11.
  • the central unit of the control unit and the flow controller 13 which controls all the coating product flows in the installation are also housed in this cabinet 11.
  • the information from the central unit 12 and the controller 13 and the necessary electrical power are transmitted to control cabinets 23 , 24, 25, 26, 27, 28, 29, 30 and 31 which respectively correspond to the lateral machines 3, 4, 5, 6, 7, 8 and 9 for the last three.
  • Each cabinet 23 to 31 contains the control elements necessary for the proper functioning of the corresponding machine 3 to 9, namely: the solenoid valves driving air, jet conformation, skirt and possibly turbine, the solenoid valves supply of coating product or rinsing product, the purge solenoid valves, the electrical control system of the turbine (if any), the positioner control systems according to the three axes of movement of the sprayer and the associated variators, the pressure switches, etc.
  • the devices contained in the cabinet 23 must control the associated piloted elements located in the machine 3, such as the motors, the turbine (if any), the variators, the positioners, the changeover blocks, Coating product, drive air feeds, skirt air feeds, conformation air feeds, etc ..., which requires many electrical conductors and fluidic conduits.
  • the beam 43 there are about thirty pneumatic tubes, represented by the beam 43 and thirty electric cables, represented by the beam 53 distributed between each cabinet, as the cabinet 23 and each machine, such as the machine 3.
  • An installation of this type includes therefore about 270 electrical cables and 270 air hoses between cabinets and associated machines. The length of these beams is very variable, as is clear from Figure 1.
  • housings 103 to 111 containing all the elements that were previously contained in the cabinets 23 to 31, respectively. These housings are integral with the bodies of the machines with which they are associated.
  • the "wiring head” cabinet 11 serves as a distributor for the electric power circuit and contains the regulation elements common to the entire installation such as the central unit 12 and the regulator 13. bundles of pipes and cables referenced 43 and 53 in FIG.
  • each box 103 to 111 may contain its own control unit 12 and / or its own flow controller 13. Each machine is then completely autonomous.
  • This variant can be designed according to the respective costs of the equipment concerned and their modularity. The electrical power can then be distributed to the different machines from the distribution network and the cabinet "wiring head" can be removed.
  • the housing 103 is pivotally mounted about a vertical axis 150, for example by hinges.
  • the housing 103 thus provides access to the interior of the machine 3. It is itself divided into two parts 103A and 103B which are connected by a pivoting joint about an axis 151. inside the housing 103 without detaching the portion 103A of the body of the machine 3.
  • the control elements are distributed between the parts 103A and 103B according to their size.
  • the housings 104 to 111 are similar to the housing 103 and mounted on their respective machines in the same way.
  • Each housing 103 to 108 is placed on the opposite side of the side machine 3 to 8 corresponding to the objects to be coated, which implies that it can be located outside the coating booth whose walls 120, 121 are generally erected in the vicinity of the front face of the lateral machine, ie the face of said machine located on the side of the objects to be coated.
  • These boxes 103 to 108 are thus easy to access, even during the operating phases of the installation. In addition, they are not immersed in a polluted atmosphere, which is important for the longevity of components, especially electronic cards. It is nevertheless true that this housing can be placed on any face of the machine, including the upper and lower faces, depending on the particular constraints of installation on the site of operation.
  • the axes 150 and 151 could thus be horizontal.
  • each housing 103 to 111 can be maintained in slight overpressure with respect to its ambient environment in order to further limit the pollution inside the housing.
  • a conventional ventilation system is provided in the housing.
