Definitions

  • the present invention relates to a mobile machine for projecting onto a fixed surface a jet of liquid, for example paint, for the purpose of tracing a colored line. More specifically, the invention relates to a machine for drawing lines by spraying liquid paint and joint movement, mainly for tracing the boundaries of the playing areas of a sports field.
  • Patent is known EP 302,037 a machine for tracing bands on a sports field in order to delimit the playing areas, these strips being formed by projecting a liquid paint.
  • This scribing machine is manually movable and comprises a frame mounted on wheels, provided with an operating handle, on which are installed a paint tank and a pump in communication relation on the one hand with said tank and on the other hand with a spray nozzle installed at the front of the machine frame.
  • the pump of the peristaltic type, is engaged by its rotor with the axle of one of the chassis wheel trains.
  • the stator of this pump has, facing the rotor, an arcuate arcuate surface of circle circumference on which the rollers of the rotor compress a suction tube and discharge the paint.
  • a closed type expansion tank To absorb the pressure and the flow rate of the pump while the nozzle is still closed is provided upstream of the nozzle, a closed type expansion tank.
  • This expansion tank occupies a lower level with respect to the bottom of the paint tank and comprises a sealed chamber in which penetrates on the one hand the delivery tube of the pump and on the other hand the tube feeding the nozzle spray.
  • the spray nozzle When the spray nozzle is closed, the penetration of the paint into the vessel compresses the air mass contained therein. The energy thus accumulated is then returned to the spraying circuit with a view, for example, to spraying paint without actuating the pump.
  • This expansion vessel further comprises a manometer which informs the user on the pressure in the spraying circuit. In this way the user can know if the pressure is sufficient to start the marking.
  • stator is movably mounted and can be angularly removed from its normal position of use by a deactivation mechanism.
  • This mechanism essentially comprises a traction cable, sheathed, secured to an operating handle attached to the handle. The spacing movement of the stator is effected against the action of a return spring which tends to bring said stator back to its initial position, that is to say in the activation position of the pump .
  • This deactivation mechanism in practice, is also used to deactivate the pump when the machine is towed back which avoids any backflow of paint to the tank.
  • Another disadvantage of the machine is closely related to the nature of the paint used.
  • the latter is usually obtained by diluting in water a base paint in aqueous phase subject to sedimentation, so that a longer or shorter period of non-use of the machine results in a deposit of the paint on the bottom of the tank.
  • this machine has no means of automatic stirring of the paint before use so that if the user is not careful, only water with low paint and therefore poorly colored will be sprayed. The quality of the marking will be greatly affected.
  • Another disadvantage of this machine lies in the fact that lying on its side for the purpose of its maintenance for example, paint present in the expansion tank and in the spraying circuit can flow back to the manometer and close the latter. irreversible. This disadvantage results in the obligation to replace the manometer.
  • the object of the present invention is to overcome the drawbacks mentioned above by using a machine of the aforementioned type for which there is no need to disengage the pump when it is moving forward with the spray nozzle closed, the pump being then used to stir the paint contained in the tank.
  • Another object of the present invention is to provide a self-cleaning machine.
  • Another object of the present invention is to provide a machine with particularly simple means to prevent paint from flowing back to the manometer when lying on its side.
  • Another object of the present invention is to provide a machine with a simplified but solid chassis.
