Definitions

  • the invention relates to a hand-dispensing gun for dispensing multicomponent masses such as, for example, two-component adhesives or two-component assembly foams.
  • the hand-dispensing gun has a handle for holding and a valve arrangement with at least one first and one further closure valve arranged adjacently in a housing.
  • the shut-off of the shut-off valves are at the same time by a single operating lever from a closed position in an open position movable.
  • the number of shut-off valves corresponds to the number of individual components and a separate shut-off valve is provided for each individual component.
  • Disposed on the valve arrangement is a removable mixing chamber nozzle which has a mixing chamber for mixing individual components flowing out of the shut-off valves and a nozzle for exiting the multicomponent mass adjoining the mixing chamber.
  • Such a device is known commercially under the name "Froth-Pak TM".
  • the hand dispensing gun is connected via hoses with pressurized aerosol cans that contain the individual components.
  • the aerosol cans are worn on the body with a shoulder strap.
  • the known device operates when using various individual components substantially reliable.
  • the invention has for its object to provide a Handdosierpistole of the type mentioned with improved properties.
  • the invention is achieved by a hand dispensing gun of the type mentioned above with the features of the characterizing part of claim 1 and with a device according to claim 10 comprising such a hand-dispensing gun.
  • Advantageous embodiments of the invention are the dependent claims 2 to 9 can be removed.
  • a first and a further receiving device for receiving aerosol cans filled with the individual components and arranged under pressure are arranged directly on the hand-dispensing gun.
  • the aerosol cans are thus not carried over long hoses separated from the hand dispensing gun, but they are used directly in the receiving devices of Handdosierpistole.
  • the receiving devices are part of the hand dispensing gun and form a unit with this. The structure of the device is thereby kept very compact, so that the handling of the hand dispensing gun is simplified due to the lack of long hoses in the application.
  • the receiving means are designed such that in these recorded aerosol cans in a horizontal working position of the hand-dose gun upside down, with a valve opening downwards can be fixed.
  • the working position an operator has enclosed the handle of the hand dispensing gun with one hand, the opening of the nozzle of the hand dispensing gun points in extension of the Gripper arm away from the body of the operator and the handle protrudes at the free end down between the little finger and the palm out of the gripping hand, while the other end of the handle is connected to other elements of the hand dispensing gun.
  • the receiving devices with aerosol cans fixed upside down are in this working position above the operating arm of the operator.
  • a direct feed connection each with only two openings, is arranged between the first shut-off valve and the first receiving device and between the further shut-off valve and the further receiving device.
  • the first opening is in this case directly connected to the respective shut-off valve and the second opening directly to the receiving device.
  • the now mixed multicomponent mass is passed on via a nozzle adjoining the mixing chamber, from where the multicomponent mass exits from the hand-dispensing gun.
  • the shut-off valves by the operating lever is in each of the inlet connections to the respective shut-off valve always only one single component.
  • a thorough mixing of the individual components takes place only in the mixing chamber nozzle, which is removable according to the invention.
  • the hand dispensing gun can be left unused for a long time before further use.
  • the mixing chamber nozzle is removed and replaced with a new mixing chamber. The hand dispensing gun is then immediately ready for use again.
  • the lengths of the feed connections differ by less than 5% from each other.
  • the feed connections are of the same length.
  • the feed connections are less than 20 cm, in particular less than 15 cm and particularly preferably less than 10 cm long. Due to this short design of the feed connections, friction losses are minimized and also the influence of external temperature conditions on the viscosity of the individual components contained in the aerosol cans and supplied via the feed connections of the mixing chamber nozzle is influenced as little as possible. As a result, the desired mixing ratio of the individual components in the mixing chamber nozzle can be set exactly.
  • the hand dispensing gun is less dependent on external thermal conditions.
  • the receiving devices are arranged mirror-symmetrically to the central longitudinal axis of the hand-dispensing gun.
  • the hand dispensing gun with the attached aerosol cans is particularly easy to perform, since the focus of Handdosierpistole with the attached aerosol cans in the working position described above is in a vertically disposed plane that passes through the central longitudinal axis of the hand dispensing gun.
  • the hand dispensing gun is balanced overall.
  • the receiving devices have threads for screwing in an aerosol can with a corresponding mating thread.
  • the first receiving device has an internal thread and the further receiving device has an external thread.
  • the aerosol cans to be inserted into the receiving devices accordingly have an external thread for the first receiving device and an internal thread for the further receiving device. If one or both aerosol cans are emptied while working with the hand dispensing gun with aerosol cans attached and must be replaced by full aerosol cans to continue work, is ensured by the above-mentioned embodiment that in the first receiving device with the internal thread again the same aerosol can with the External thread is screwed and not about that aerosol can of the type or with the single component, which was previously used in the other receiving device. This ensures that different individual components do not mix with one another in the case of two-component systems inside the hand-held metering gun before the mixing-chamber nozzle and react there.
  • the receiving devices each have a stop on which a valve rod of a solids valve of an aerosol can to be received in the receiving device, the solid valve is openable pressing.
  • the valve rod is pressed against the stop, whereby the solid valve of the aerosol can is opened.
  • the shut-off of the shut-off valves are designed as a single shaft which has a plurality of bores guided parallel to one another, in which case each bore is assigned to a shut-off valve.
  • the shut-off may also be formed as mutually firmly connected balls, each ball having a bore which is guided parallel to the other holes.
  • the shut-off can be spent simultaneously by the operating lever from a closed position to an open position.
  • the design of the shut-off valves is also very stable with simple means, so that no kickback and a concomitant, unwanted material entry from the mixing chamber via a shut-off valve in the feed connections. When the shut-off valves are closed by means of the shut-off bodies, this ensures in each case that there is always only one individual component in each of the feed connections so that they can not react with other components and thereby block the feed connection.
  • the invention is further realized by a device for dispensing multicomponent masses comprising a hand dispensing gun of the aforementioned type, comprising at least a first and another aerosol can, each having a solids valve, which has a valve plate which is completely against a valve spring against the force of a spring Valve seat, the content of the aerosol can releasably wegbewegbar is.
