Definitions

  • the invention relates to a spray gun system for dispensing sprayed material according to the preamble of claim 1.
  • Spray gun systems in particular for water-dilutable and solvent-containing sprayed, such as paints, varnishes, glazes, primers, stains, wood preservatives or the like, are currently available in various designs.
  • the spraying method used is usually the low-pressure spraying method, which is a method in which sprayed material sprays at a low pressure of about 0.2 to about 0.5 bar and with a high volume of air at about 200 liters per minute becomes.
  • This HVLP spraying process achieves a low overspray, i. H. because of its low spray losses, coating levels up to about 65%, and thus superior to conventional processes that achieve coating levels between about 20 and about 35%.
  • Characteristic of the method is the air surrounding the spray material, which reduces overspray and color fog. This results in advantages such as paint savings and low solvent emissions, which have a particularly environmentally friendly effect.
  • both the switching mechanism for turning on and off the compressed air generating unit and the valve operating mechanism for opening and closing the valve unit must be operated.
  • the switching mechanism normally comprises a control element designed as a tilting, pushing or sliding switch, with the aid of which the motor of the compressed air generation unit, which is normally provided in the form of a compressor or a radial fan, is switched on and off can.
  • the valve operating mechanism usually has an operating switch in the form of a trigger-like switch trigger provided near the handle of the spray gun so that it can be operated by the operator while holding the handle.
  • the switching mechanism and the valve actuating mechanism are thus provided as independently operating units with separately arranged controls.
  • both controls must either be operated simultaneously, which usually requires a cumbersome two-handed operation by the user, or they are operated sequentially, which is also quite unwieldy.
  • the switching on and off sequences of the switching mechanism and the valve actuating mechanism by the user are arbitrary, which may involve the risk of malfunction with it.
  • Spray gun systems mentioned in the preamble of claim 1 are for example from the DE 20 2007 004 699 U1 , of the US-B1-7 303 149 and the EP-A-1 602 411 known.
  • the operation of the switching mechanism for turning on and off the compressed air generating unit as well as the valve actuating mechanism for opening and closing the valve unit via a common operating switch to facilitate operation and to avoid operator errors.
  • these spray gun systems are each operated such that the switching mechanism for switching on and off of the compressed air generating unit when switching on the spray gun system is always operated in front of the valve operating mechanism for opening and closing the valve unit, which is to ensure that sprayed is sprayed only if sufficient Air flow is available and that no drops are formed when switching on and off.
  • a compressed air reservoir in the form of a gas cartridge is provided instead of an electrically driven compressed air generating unit and it is the valve actuating mechanism for opening the valve unit when switching on the spray gun system before Switching mechanism for switching on the compressed air supply actuated. This in order to limit the action of the compressed air on the sprayed material on the period of spraying and to prevent in the intervening time, the absorption of compressed air by the Sprühgut.
  • the invention has for its object to further improve a spray gun system of the type mentioned in particular with regard to the handling conditions and the achievable work result.
  • both mechanisms are operated via a single control switch, which cooperates with both the switching mechanism and the valve actuating mechanism, a simple and convenient handling is ensured.
  • the determination of the timing of the operation of the mechanisms by the single control switch can be done for example via one or more lever systems that are operated simultaneously or sequentially and cause switching on and off of the compressed air generating unit and an opening or closing of the valve unit.
  • valve unit can also vary the amount of spray that flows through the valve unit per unit time, vary in a range between a minimum amount of spray and a maximum amount of spray, so that the sprayed amount of the user are flexibly adapted to a variety of applications as needed can.
  • control switch and the mechanisms according to the invention are matched in their design interpretation to one another such that the valve actuating mechanism is always actuated when switching on the spray gun system in time before the switching mechanism. In this way it can be ensured that when switching on the compressed air generating unit immediately sprayed material is discharged from the spray nozzle of the spray gun.
  • the adjusting device comprises at least one marking which defines a defined basic position corresponding to a given predetermined amount of sprayed material per unit time, and the adjustment is designed such that the spray quantity is increased starting from the basic position optionally or can be reduced while passing through the basic position emits a signal, the user is given an orientation aid with respect to the current setting of the adjustment.
  • the signal emitted during the passage through the basic position can expediently be generated by latching elements of the adjusting device coming into and out of engagement with each other, and the adjusting device advantageously comprises further markings which are designed to indicate to the user of the spray gun in which direction the adjusting device is to increase or to operate to reduce the amount of sprayed material per unit time.
  • Such further markings can be provided for example in the form of a plus and a minus sign.
  • the adjustment device is advantageously arranged on the handle of the spray gun, so that it is easily accessible to the user while he operates the control switch. Accordingly, the user can do the per unit time regulate the amount of sprayed material to be dispensed during the handling of the spray gun without any problems in accordance with the current requirements.
  • the setting device is positioned directly on the operating switch, so that the operating switch and the setting device form a common unit.
  • the adjustment device is preferably provided laterally on one or better still on both sides of the operating switch, whereby an optimal handling of the adjusting device is achieved.
  • the adjusting device comprises a displaceable regulator, which is preferably positioned such that it can be adjusted back and forth approximately in the dispensing direction of the injection molding material. In this way, a particularly ergonomic handling of the movable regulator is achieved.
  • the adjusting device comprises a rotatable regulator, which is preferably adjustable in an ergonomic respect in a direction transverse to the dispensing direction of the injection molding.
  • the adjusting device can be designed such that the amount of sprayed material which is to be dispensed from the spray nozzle per unit of time is adjustable in at least two stages or continuously.
  • the stepwise adjustment facilitates the operation of the adjustment device for a non-expert user or a user who rarely uses the spray gun.
  • a stepless adjustment is advantageous in terms of the flexibility of the spray delivery.
  • the adjusting device preferably has a stop which limits a movement path of a movably arranged lever of the valve actuating mechanism, wherein the stop is adjustably designed to vary the adjustment path of the lever.
  • the stop can be moved by operating the slidably or rotatably formed regulator so that the movement path of the lever is shortened or lengthened, whereby the amount of sprayed material which is discharged from the spray nozzle per unit time, is correspondingly reduced or increased. In this way, a structurally very simple adjustment can be realized.

  • the spray nozzle 30 is such that the user can set various beam shapes and beam directions in which the sprayed material is dispensed, such as a point beam, a horizontally extending elliptical beam, or a vertically extending elliptical beam. Accordingly, the jet shape of the injection molding can be adapted to a specific application.
  • a spray container 32 is releasably attached. This releasable attachment can be done for example by means of a screw, a connector, a snap-in connection or the like.
