Definitions

  • the invention relates to an automatic membrane gun used for spraying products, in particular spraying abrasive or enamel paints, water-soluble or dissolved in a solvent.
  • Spray guns in which the spray of the product is obtained exclusively hydrostatically, that is to say by applying a pressure on the product and out through a nozzle at the front end of the gun.
  • Spraying can also be achieved pneumatically, but generally a combination of the two is used, which means that the hydrostatic spray is combined with jets of compressed air which, in addition to a jet of central air spraying, serve to adjust the shape and / or dimensions of the jet of sprayed product.
  • the invention relates more particularly to automatic membrane guns in which the membrane is controlled by pulsed air so that the product, which is fed into the gun under constant pressure, comes out of the nozzle by intermittent spraying.
  • the diaphragm is driven in an oscillation movement by pneumatic means for controlling the pulsed filling of the feed of the product comprising a pulsed air supply which communicates with an annular chamber formed in the gun body around the rod of a control piston which, when actuated by the pulsating air, is moved backwards against the action of an elastic return means.
  • the piston thus moves back and forth at the frequency of the pulsed air.
  • the forward end of the piston rod rests against the diaphragm in a central area thereof to impart an oscillating motion thereto.
  • the product to be sprayed is fed under pressure into a product receiving chamber which is immediately in front of the membrane and which towards the rear is delimited by it.
  • This receiving chamber communicates through a central opening with a central product supply channel arranged in the spray head and which opens directly into the nozzle.
  • the central opening is closed by intermittent sealing means constituted by the membrane itself which is then pressed by the end piston rod against the peripheral area around the opening which thus forms a seat.
  • the diameter of the end of the piston rod is substantially larger than the internal diameter of the opening.
  • this seat is thus at one end of the central channel whose opposite end opens into the nozzle, so that when the control means of the pulsed air are no longer actuated, that is to say ie when the spray is stopped, the entire volume of the central channel is a residue of the product whose flow through the nozzle can not be prevented, causing soiling.
  • This diaphragm spray gun further comprises pulsed supply means for spraying air opening near the spray nozzle to improve the spray and to form the jet of the product.
  • the atomizing air is supplied independently of the pulsed output of the product by means of a programmable controller which supplies the spray air into an annular chamber formed in the spray head and which communicates with a first set of orifices. or air nozzles opening close to the exit of the nozzle and with a second set of orifices located in a crown placed at the front end of the gun body. This arrangement allows the orifices of this second set of orifices to direct the spray air jets at a much greater angle to the jet of the product exiting the nozzle.
  • a general problem which affects membrane spray guns as well as the others which operate with a needle valve lies in the fact that some parts are very exposed to wear, especially when the product is an abrasive product such as a paint with enamel. This is primarily the nozzle, but also the membrane in the case of membrane spray guns and the needle in the case of needle spray guns. All these wear parts thus require a regular replacement that must be done more or less often depending on the abrasive nature of the product. It is therefore desirable to extend the life of these wear parts and / or to facilitate their replacement.
  • the object of the invention is to remedy all the drawbacks mentioned above by proposing an automatic membrane spray gun which avoids contamination by the flow of a residue of the product when the gun is stopped, which operates without problem at a high frequency with an immediate and integrity response to the pulsation of the diaphragm, which is provided with a simple supply of spray air and at least some of the wear parts of which are designed to allow increased service life and / or replacement ease.
  • the object of the invention is an automatic membrane gun for spraying a product such as a paint fed with constant pressure into the gun, comprising means for pulsed spraying of the product comprising an oscillation membrane associated with means for intermittently closing the supply of the product to a nozzle, and pneumatic control means of said pulsed product spraying means, characterized in that said sealing means comprise a punch integral with the oscillation membrane and passing therethrough so as to be connected to a pulsation control member comprising a piston rod connected to a piston controlled by pulsed air.
  • the automatic pistol shown in the drawings is a membrane gun of the type in which the product spray is obtained by pulsed spraying of the product fed into the constant pressure gun, in combination with a pulsed supply of atomizing air which in addition to spraying allows to adjust the shape and / or dimensions of the jet of sprayed product.
  • the process of spraying and adjusting the jet of product sprayed by the compressed air jets is well known and, not forming part of the invention, it will not be described in detail.
  • the gun comprises a body 1 which, preferably, is made of light metal.
  • This body is at its front and rear ends extended by a cylindrical protuberance before 2 and respectively a rear protrusion 3, which are threaded externally.
  • the front protuberance carries a spray head 4 and the rear protrusion carries a cap 5 inside which are housed intermittent output control means of the product to be sprayed.
  • the product is supplied under constant pressure by a pipe 6 in a product feed chamber 7 arranged in the front part of the gun and having a generally frustoconical shape with the smaller diameter end opening directly into a central channel 8 of the head 4.
  • the means for obtaining the pulsed spraying of the product comprise a membrane 10 disposed at the end of the larger diameter of the chamber of spray. brought frustoconical 7.
  • the periphery of the membrane 10 is clamped between a front portion 1 'and a rear portion 1 "of the body 1. These two parts 1' and 1" are assembled by screwing and must be separated for the change of the membrane. to wear caused by the product on the front side of the membrane.

  • the face exposed to this wear is according to the invention coated with a layer of polytetrafluoroethylene (PTFE), which substantially increases the life of the membrane.
  • PTFE polytetrafluoroethylene
  • the membrane 10 is according to the invention mounted oscillating with a needle 11 extending in a central through bore 12 of the second portion 1 "of the body 1 and which is connected to control means reciprocating at this needle
  • the needle 11 passes through the membrane 10 through a central hole (not shown) of the latter and is secured to the latter by clamping means consisting of flanges 13, 14 integral with the needle and disposed on either side of the membrane 10 in order to clamp them together.
  • the front end of the needle can, as shown in figure 1 , abut against a seat 15 immediately behind the nozzle to form together intermittent sealing means of the supply of the pressurized product into the nozzle.
  • the product passes from the product inlet chamber 7 to the nozzle 9 by an annular spacing defined between the inner wall of the central channel 8 and the outer face of the needle.
  • the space behind the membrane 10 in the product inlet chamber is vented through a conduit 16.
  • the needle 11 is guided in a guide sleeve 17 placed inside the central bore 12 and provided with seals 18.
  • the nozzle 9 thus constitutes, with the needle 11 and the membrane 10, pulsed atomization means for the product controlled by pneumatic control means comprising a forced air supply pipe 19 connected to a conduit 20 which opens into an annular chamber 21 formed around a piston rod 22 extending in the central bore 12 to be connected to its piston 23 which is guided in the cap 5.
  • pneumatic control means comprising a forced air supply pipe 19 connected to a conduit 20 which opens into an annular chamber 21 formed around a piston rod 22 extending in the central bore 12 to be connected to its piston 23 which is guided in the cap 5.
  • the pulsed air coming through the pipe 19 is fed into the annular chamber 21 so as to push the piston 23 against the effect of a return spring 24 bearing on one side against the piston and the on the other side against an inner wall of the cap 5. Reciprocating movement of the piston 23 and thus also the needle 11 which drives the diaphragm 10 in a swinging motion.
  • the figure 1 shows the advanced position of the needle between two pulses of the control air admitted into the annular chamber 21 by the air duct 20, this position also corresponding to the position of the needle when the gun is stopped. In the latter case, there is no product leakage through the nozzle 9, since the end of the needle is in abutment against the seat 15 immediately behind the nozzle.
  • the device Between two pulses of control air, the device returns to the position shown in FIG. figure 1 by a displacement of the piston 23 towards the front, under the effect of the action of the return spring 24, to thereby move the needle 11 forward by driving the membrane through the central zone thereof and that up to the needle presses against its seat 15 in order to close the access of the product to the nozzle.
  • spray gun is also provided with pulsed air supply means for spraying air opening near the spray nozzle 9.
  • spray air supply means comprise a compressed air pipe 25 connected to an air duct 26 opening into a generally circular air inlet chamber 27 arranged around the needle 11 in the rear part 1 "of the body 1 of the gun
