Definitions

  • the invention relates to a coating product spraying method and device used, in particular, in installations where the supply of a coating product sprayer is carried out from a piston tank.
  • the flow rate of coating product is sometimes controlled relative to the speed of the conveyor which transports objects to be coated, such as motor vehicle bodies.
  • a computer determines, at given time intervals, of the order of a few seconds, and as a function of the speed of the conveyor, a set value for the paint flow rate which must be delivered to a projector during the following time interval.
  • the speed of movement of the piston is thus controlled relative to the speed of movement of the objects.
  • the accuracy of the conveying speed of the bodies is as important for the surface finish obtained as the accuracy of the flow rate of coating product supplied to the headlight.
  • the invention solves all of these problems.
  • It relates to a method of spraying coating product by means of at least one sprayer supplied with coating product from a piston tank, characterized in that the position of the piston of the tank is controlled by the relative position of the sprayer with respect to the objects to be coated.
  • the invention also relates to a device suitable for implementing this method and more specifically a device for spraying coating product onto objects transported by a conveyor, said installation comprising a projector supplied with coating product from a piston tank, characterized in that it comprises means for controlling the position of the tank piston with respect to the relative position of the headlight with respect to the objects.
  • the invention applies equally well to the case where the objects to be coated pass in front of the projector, possibly mobile, or to that where the objects are fixed during the coating phases and where the projector is mobile, for example carried by the arm of 'a multi-axis robot.
  • the projector can be carried by a side machine or a roof machine.
